I created it for the accessible data analytics. It&#x27;s nice to be able to answer certain questions about the local weather.

Very cool. Was this to learn about websites and sql, or you just wanted to extremely accessibly data analysis?

I wrote <a href="http:&#x2F;&#x2F;idaweather.com" rel="nofollow">http:&#x2F;&#x2F;idaweather.com</a> to get a better understanding of the local weather where I have a hobby farm.It&#x27;s mostly a toy but it has given me great insight into local weather patterns.

That&#x27;s pretty nifty. Security first.

Not all that interesting but I recently built a server for 2FA.It mainly consists of a simple CLI utility that generates TOTP codes using an AES encrypted lookup table of secrets.I piggybacked access to this off an unrelated web site and it is now readily available from any device if you can provide the decrypt and lookup key and know the URL.

&gt; I have one of those AC units in my apartment that sits on the floor with an outlet tube terminating at a window to pipe out hot airYou might want to add an intake tube, to cool the compressor more efficiently: <a href="https:&#x2F;&#x2F;imgur.com&#x2F;gallery&#x2F;kA4Z0uV" rel="nofollow">https:&#x2F;&#x2F;imgur.com&#x2F;gallery&#x2F;kA4Z0uV</a>

Why not just have it drain into an ordinary condensate pump which is built for this purpose? Those roll around ACs usually have a spigot to attach a hose you can run into a drain.

Curious why not pump it out of the window? It’s only going to be a few dribbles every few hours.

I suppose this counts: Although not that interesting, I have one of those AC units in my apartment that sits on the floor with an outlet tube terminating at a window to pipe out hot air. The internal reservoir for this unit is quite small so I hacked together a float valve that triggers a pump to offload the condensation water to a larger bin, that way I don&#x27;t have to empty the reservoir as often.Pretty simple, but saves lots of time and I don&#x27;t have to worry about the air conditioner turning off in the middle of the night due to it&#x27;s internal reservoir becoming full.

I grew up playing a multiplayer competitive solitaire with my family called Nerts. Sounds like a similar game: <a href="https:&#x2F;&#x2F;bicyclecards.com&#x2F;how-to-play&#x2F;nerts" rel="nofollow">https:&#x2F;&#x2F;bicyclecards.com&#x2F;how-to-play&#x2F;nerts</a>

My family is super into games, and as the resident programmer, they often ask me to build things related to them. Favorite two to build were- an Unolingo solver that we used to figure out if there could ever by more than one solution to the puzzle (there can be!)- a &quot;killer&quot; solitaire simulator that determined the optimal number of players for a max win rate. IDK if this is even a real game, but my family plays multi-player competitive solitaire with up to 8 people at a time. IIRC the optimal number for win rates is like 5-6(?) according to my simulation

It was neat but I never thought it would go anywhere. The idea was kind of like being able to leave virtual graffiti.  So anyone could leave their &quot;Kilroy was here&quot; but without actually defacing anything.

That geolocation messaging sounds brilliant. I guess Pokemon Go stole your idea.

Whoa, that DVD changer is almost as big as a server rack. I&#x27;d love to have that in my garage.

Way back in the day before space was a non-issue I bought a used pioneer 720 disk DVD changer. Wrote a frontend to control it and mount the DVDs over iscsi for my media center.Also many years back when I was traveling all the time I created a thing based off the what 3 words data where I could geo drop messages at a location. My friends and I used it for a while but then just forgot about it.

I might actually use this. Always looking for vocab helpers.

broca, a chatgpt powered dictionary + vocabulary book I&#x27;m working on.<a href="https:&#x2F;&#x2F;github.com&#x2F;shi-yan&#x2F;broca">https:&#x2F;&#x2F;github.com&#x2F;shi-yan&#x2F;broca</a>on each of the computers I use, I have a open sublime text tab documenting words I don&#x27;t know.they are scattering around, unorganized, get lost when the file tab is closed.I want to synchronize my vocabulary on different devices using git.broca saves to plain files that are git friendly. And using ChatGPT as a dictionary allows me to search for idioms&#x2F;slang&#x2F;phases with unlimited example sentences.

I wrote an app to do that with my Tesla.The Tesla app is great, but with one caveat: it won&#x27;t let you turn on climate controls until the car has &quot;woken up&quot;. Upon opening the app, this usually takes 5-15 seconds, but when I first got the car, sometimes took a full minute.Someone else had already reverse-engineered the Tesla API, and I wrote a quick app that would just let me press a button and it would wait for the car to wake up and turn on the climate controls in the background.

After getting an EV many years ago (not a Tesla) which had a truly terrible phone app for checking charge status, starting charging and turning on the heater remotely, I reverse engineered the API and wrote my own web-based tool to control the car. It worked great until 3G was disabled last year.

I have definitely tried to build something similar after all. People are so particular with these things.

It&#x27;s called Epiphany Workflow. It&#x27;s on the Apple App Store.  I charge $20 for it.  I&#x27;m making absolutely no money on it.  Just now I changed the price to Free.  I hope it&#x27;s useful.  Feed back in hugely important.

Sounds interesting, do you have a github repo for it?

I wrote an app for reviewing and highlighting websites and most computer documents.  I can drag the highlights into a  built-in outliner and organize and comment them there.  I can drag relevant highlights into a built-in report outliner where I can write the corresponding section of the final report.  I knew I wanted it.  I thought others would too.  I was wrong on that.  Sigh!  I guess I built it just for myself after all.

It&#x27;s something I&#x27;m thinking about.The system right now is highly reliable, I have no fear of doing a live demo of it, but live demos come off as strange because my feed is a strange mix of arXiv abstracts, Guardian articles about association football, etc. so it comes off as idiosyncratic and personal. (Oddly when I started this project I loved the NFL and hated the Premier League, when I started doing feature engineering as to &quot;Why does it perform so well for arXiv papers and so poorly for sports&quot; I started studying football articles in detail and started thinking &quot;How would I feel if my team got relegated?&quot; and &quot;Wow, that game went 1-0 and it was an own goal&quot; and next thing I knew I was hanging on every goal in every game Arsenal and Man City play -- it changed me.)It&#x27;s not even that hard for me to swap algorithms in and out but it should be easier, for instance I like the scikit-learn system for model selection mostly but there are some cases like SVC-P where I want to bypass it and I am not so sure how to comfortably fit fine-tuned transformer models into the system.Another problem with it is that it depends on AWS Lambda and Suprfeeder for ingestion, it costs me less than $5 a month to run and about 10 cents per feed but (1) that&#x27;s not cost-effective if I want to add a few hundred blogs like<a href="https:&#x2F;&#x2F;www.righto.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.righto.com&#x2F;</a>and (2) I know many people hate AWS and other cloud services.If somebody were interested in contributing some elbow grease that would help the case for open source, alternately a hosted demo of some kind would also be possible but I&#x27;m not ready to put my time and money into it. Contact me if you&#x27;re interested in finding out more.

Do you have public source code for this? Looks great.

Area under <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Receiver_operating_characteristic" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Receiver_operating_characteris...</a> curve.It&#x27;s by no means perfect. For one thing if I have a choice of 0.78 ROC based on 40 days worth of data and 0.77 based on 10 days worth of data I&#x27;d take the later because I know the later one adjusts more quickly to my changing preferences. Also my selection algorithm breaks up the input into (say) 20 clusters and shows me the (say) 15 top results in each cluster and I know I like the results from that better than if I just take the highest ranking results.

What do you mean by &quot;outperform&quot; in this context?

Interested in your filters, or a link to your results!

On the one hand, &quot;echo chambers bad&quot;, on the other hand, I&#x27;d be lying if I didn&#x27;t acknowledge that what floods and outnumbers most other content is a form of signal-to-noise ratio manipulation, and is thus creating an artificial echo chamber by sheer volume.Would love to know more. I&#x27;m a sucker for anything RSS.

Your post resonated with me a lot.I&#x27;m jealous! Experiencing the world with all the garbage filtered out.

I too have an (private) RSS &quot;laboratory&quot; project!It isn&#x27;t the elegant machinery you describe here as I&#x27;m quite unfamiliar with the technique you describe.If I&#x27;m actively using it the feed list grows to about 35-40 000 at which point I find as many new feeds as I lose old ones.I maintain a dozen categories of badwords, if any of those are in the headline it will be removed.With many subscriptions things look quite different, higher frequency publishers start dominating the top of the newest list. The faster they publish the higher the standards I hold them to.What is quite amazing is that some really terrible news websites use long titles that are highly descriptive. I have a good few of those, they get to stay around because the badword filter purges so much I hardly ever see them. For every 2000 bad ones business insider has a great article. It&#x27;s a terrible website but their use of descriptive words in article titles is the best in the world.The key insight imho is that the internet is much more of an echo chamber than people think.As soon as you get rid of Musk and a few hundred other people, a few hundred companies, a dozen countries and a few thousand other topics you are left with a world of infinite other subjects. People are writing about stuff no one else ever thought of.If everyone in the world is reading and writing about FOO it is absolutely amazing to get rid of FOO. There is no such thing as an important football match. (joking sorry)Everyone is praising normality but you should really wonder who creates these norms. If they are good of bad people is besides the point. Musk says 1 something interesting per day I&#x27;m sure. For every 100 000 topics inserted into the collective we chose 1 then, by the tens of millions, we talk about it. Every day is Musk day.It doesn&#x27;t matter how hard you resist participating, eventually you will learn that space x launched a rocket. There is no avoiding it.Autonomy is something fucking amazing. I imagine millions of articles are published per day. 99% things said before. What part should I want to read? The 1% with the most traffic?You should get on the train to nowhere just like everyone else - they say. Stop wandering around on your own, you should get on the train just like me!I&#x27;m not usually telling anyone not to get on the train. If people want to discuss &quot;rss is dead&quot; for the ten thousandth time, let them. They think they chose the topic themselves.There is 13 billion years of history, 6000 sq km of earth, 7.9 billion people alive, 100 billion dead, 8.7 million species of plants and animals, 350 thousand chemical compounds, 130 million books since the printing press, 100 billion stars in the milky way alone. What to spend my time on? The Trump investigations? Really?I&#x27;m sorry for not being very technical.

Nice approach! I added a very basic keyword filter in my rss reader (<a href="https:&#x2F;&#x2F;github.com&#x2F;lallassu&#x2F;gorss">https:&#x2F;&#x2F;github.com&#x2F;lallassu&#x2F;gorss</a>) to do some sort of &quot;cleaning&quot;. But having a section in the reader that would filter out the articles more intelligent would be very nice, and maybe bundled them into clusters.

Amusing. I, too, wrote my own ML-powered newsreader. (Not linking here because I don&#x27;t want to de-anonymize my HN handle.)I guess this is a thing people do. ;)

I do something similar for my personal news reader. [1]. Originally I had done it so I can read my tech news quickly. Now few of my friends also have started using it.[1] <a href="https:&#x2F;&#x2F;embit.ca" rel="nofollow">https:&#x2F;&#x2F;embit.ca</a>

I also wrote my own feed aggregator (<a href="https:&#x2F;&#x2F;mofeed.news" rel="nofollow">https:&#x2F;&#x2F;mofeed.news</a>) from scratch in Go. It can connect to twitter, reddit, spotify&#x2F;itunes(podcasts), rss, medium, youtube, etc.It has a good search engine (meilisearch) and also supports newsletter (each user has an inbox).I&#x27;m currently testing it and have a few test users for feedback. I hope I can open source it sometime this year, after integrating the feedbacks, and polishing the code.It&#x27;s not intelligent for now, but that&#x27;s by choice. Instead, I prefer to have custom rules for filtering (e.g., adding tweets from user X to feed only if the likes are above a threshold). I may use GPT for summarization later, but honestly most of the posts are either short (e.g., tweets), or they come from websites that have description&#x2F;summary in their meta tags.Please shoot me an email to `hey@mofeed.news` if you want to test it :)

Cool!I&#x27;ve been hacking on a related side project -- in my case, I wanted something like this but for Twitter. Right now it&#x27;s using gpt-3.5-turbo to cluster related Tweets &amp; rank based on my interests.Source is here: <a href="https:&#x2F;&#x2F;github.com&#x2F;kasrak&#x2F;feedpaper">https:&#x2F;&#x2F;github.com&#x2F;kasrak&#x2F;feedpaper</a>

I agree. I have built a &#x27;new tab&#x27; website for me and included a widget with the top 3 from the HN best list. So I am very happy with about 1-2 per day ;-)Btw. this is the way I found this thread :D

Skimming 300 articles per day sounds exhausting

How does the bit that determines if 2 articles are really about the same story work? How did you structure training data for that and get a training set?

<a href="https:&#x2F;&#x2F;github.com&#x2F;piqoni&#x2F;matcha">https:&#x2F;&#x2F;github.com&#x2F;piqoni&#x2F;matcha</a> can summarize feed articles with gpt3.5 , but not categorize yet

Smart RSS reader that, right now, ingests about 1000 articles a day and picks out 300 for me to skim. Since I helped write this paper<a href="https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;cs&#x2F;0312018" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;cs&#x2F;0312018</a>I was always asking &quot;Why is RSS failing? Why do failing RSS readers keep using the same failing interface that keeps failing?&quot; and thought that text classification was ready in 2004 for content-based recommendation, then I wrote<a href="https:&#x2F;&#x2F;ontology2.com&#x2F;essays&#x2F;ClassifyingHackerNewsArticles&#x2F;" rel="nofollow">https:&#x2F;&#x2F;ontology2.com&#x2F;essays&#x2F;ClassifyingHackerNewsArticles&#x2F;</a>a few years ago, after Twitter went south I felt like I had to do something, so I did. Even though my old logistic regression classifier works well, I have one based on MiniLM that outperforms it, and the same embedding makes short work of classification be it &quot;cluster together articles about Ukraine, sports, deep learning, etc.&quot; over the last four months or &quot;cluster together the four articles written about the same event in the last four days&quot;.I am looking towards applying it to: images, sorting 5000+ search results on a topic, workflow systems (would this article be interesting to my wife, my son, hacker news?), and commercially interesting problems (is this person a good sales prospect?)

I wrote a hearthstone simulator when the game came out.<a href="https:&#x2F;&#x2F;github.com&#x2F;jleclanche&#x2F;fireplace">https:&#x2F;&#x2F;github.com&#x2F;jleclanche&#x2F;fireplace</a>It was used and referenced by a few scientific papers and phds since. It’s my little pride, even though it would really need a rewrite at this point to work properly with all the additions in the game.It contains its own little python driven dsl for actions. I could talk about it for hours. All that work led to me starting a company around hearthstone (I have since left it behind but it eventually grew into other games).

I wrote my own firmware for ESP-8266 IoT devices to connect them to Home Assistant. There are many like it, but this one is mine: <a href="https:&#x2F;&#x2F;github.com&#x2F;thedanbob&#x2F;mqtt_light">https:&#x2F;&#x2F;github.com&#x2F;thedanbob&#x2F;mqtt_light</a>

Malware scanner for anything uploaded to web servers. Was pretty cool at the time learning and identifying things in the wild then creating custom rulesets.

„Shortcuts“ are a feature in iOS<a href="https:&#x2F;&#x2F;support.apple.com&#x2F;guide&#x2F;shortcuts&#x2F;welcome&#x2F;ios" rel="nofollow">https:&#x2F;&#x2F;support.apple.com&#x2F;guide&#x2F;shortcuts&#x2F;welcome&#x2F;ios</a>

I&#x27;m guessing this wasn&#x27;t literally a shortcut

A shortcut on my iPhone, that I can dictate a note to, and it transcribes it and puts it into my GTD inbox in Notion. It helps me not forget things. Lowers the friction and allows me to make note of fleeting ideas, thoughts, and things to get done.

I feel like there&#x27;s a whole suite of tools that we need to be used with netflix to make our lives easier.

Not very interesting, but used VB script to make Netflix sleep timer for the active tab. (looks for the browser process, makes the windows active,sends a ctrl+W to the window to close the video player, and finally sleeps the display.This way I can fall asleep to noise that doesn&#x27;t later wake me up.

It will change station to station, but if you open the station details page, adjust X Range to something like 28&#x2F;180 days, then tune low pass to filter out all the high frequency (daily) fluctuations, you might get your answer. Some stations don&#x27;t have strong Solar contributions, and won&#x27;t change much on an annual basis, you can enable the Harmonics toggle and see if any show up on the outside in yellow (disable Sun).I did consider adding a &quot;max finding&quot; mode of some sort, but that&#x27;s never really been my use case.

that is cool, but I&#x27;m curious when the highest tide vs lowest tide of the year is.

Cool! Would love to have some extra datapoints. This is what the raw data I use looks like <a href="https:&#x2F;&#x2F;tidesandcurrents.noaa.gov&#x2F;harcon.html?id=9410580#" rel="nofollow">https:&#x2F;&#x2F;tidesandcurrents.noaa.gov&#x2F;harcon.html?id=9410580#</a>

If you are OK with R, there is some good code here that makes predictions from harmonics:

I’ve wanted to do this with Canadian data for years! My wife works for the organization which tracks our national tide data and builds our prediction models. It’s extremely fascinating stuff.I’m looking forward to digging into your work. I haven’t really known where to start, but I can probably get a lot of inspiration here. Nice work!

I use MouseGestures so I often get fun surprises on projects like this when I right-click and then drag my cursor to close the tab. Yours might have been the best one yet!

It&#x27;s a very nice, UI.  The &quot;viewing port&quot; concept is very nice.  A slider for timescale in the viewing window would be great!
Also would be great to see worldwide cities tides :)
edit: using the x-range view is an interesting time slider - I found the options toggle

Unfortunately while US&#x27;s NOAA provides all the data needed free of charge (with an API to boot), the UK government&#x27;s equivalent charges an MSRP of £38.30 and requires finding and contacting an authorized distributor, though the data does seem to be more worldwide. I haven&#x27;t seen other offerings.<a href="https:&#x2F;&#x2F;www.admiralty.co.uk&#x2F;publications&#x2F;publications-and-reference-guides&#x2F;admiralty-tide-tables" rel="nofollow">https:&#x2F;&#x2F;www.admiralty.co.uk&#x2F;publications&#x2F;publications-and-re...</a>

Looks nice, would love something like that for Europe.

A website to see a map of the world&#x27;s tides, and bidirectional predictions for individual stations (edit: worldwide too, forgot I added that). The UI&#x2F;UX is... archaic, but that&#x27;s just how I wanted it. It works fully offline. <a href="https:&#x2F;&#x2F;solunar.pages.dev" rel="nofollow">https:&#x2F;&#x2F;solunar.pages.dev</a>Most fun part was transcribing 70+ year old NOAA tide calculation mathematic&#x2F;astronomic&#x2F;hydrologic research papers into modern TypeScript.

I did the same thing, but not for myself, it was to send other people away that I didn&#x27;t like

I did something similar, but gave up chasing parasitic electrical losses and didn&#x27;t want to make the solar panel to power it huge.

Chicken coop auto-door opener so I don&#x27;t have to get up at 4AM in the summer. It was just a basic Arduino system but I learned that large canning jars make excellent enclosures: waterproof, reusable, easily modified and replacable lid.

Uh, what kind of graph network? That sounds pretty interesting.

@RedGreenBlack : could you share more please ?

A webbapp that helps me remember names by showing them in a graph network. Super simple, use it constantlyA webapp for sharing files&#x2F;text between two devices no matter the platform. Use this all the time. No more sending emails, Facebook message, dropbox link to yourself.

I had the wrong path for the demo file. It ought to work now.

The site you linked isn&#x27;t loading for me. It&#x27;s just a black page with a favicon

MUDs are a great breeding ground for bespoke programs. I&#x27;ve made my own system of triggers and aliases in Rust, which interfaces with Mudlet (very popular MUD client) through JSON over stdio. Being written in Rust, it has enabled a publicly usable web tool (<a href="http:&#x2F;&#x2F;seurimas.github.io&#x2F;topper&#x2F;explainer&#x2F;?&#x2F;topper&#x2F;explainer&#x2F;helps&#x2F;demo.json" rel="nofollow">http:&#x2F;&#x2F;seurimas.github.io&#x2F;topper&#x2F;explainer&#x2F;?&#x2F;topper&#x2F;explaine...</a>), but the majority of the code is just for me.

Well that&#x27;s what you get for building something no one wanted...

<a href="https:&#x2F;&#x2F;hyperscript.org" rel="nofollow">https:&#x2F;&#x2F;hyperscript.org</a>I wanted to have a scripting language that was inspired by xTalk for some light front end work alongside htmx. Didn&#x27;t expect it to go anywhere.

If you&#x27;re going for multi-threaded and &quot;frees all memory at the end&quot;, it&#x27;s probably going to be way easier to write it in Rust, and you should end up with essentially the same result.

I wrote a program in C++ to download massive amounts of stock data from a data provider. The binary itself is 2 MB, memory use rises to over 16 GB and it frees everything at the end, so there are no memory leaks (I&#x27;m particularly proud of that). Over the years I&#x27;ve found better and better ways of making it run faster because a daily run will take over 6 hours of downloading and writing to my database.I also wrote a multi-threaded backtester in C++ because the program I was using was only single-threaded. I stopped using that several years ago but the act of writing it was a lot of fun.

This sounds very cool! I recently moved from a FAANG company to a smaller one, and I&#x27;m _really_ missing the functionality their development tools provided (including this, which I agree is fantastic and sorely missing from the core GitHub experience).

If I understand correctly, this is like normal Git three way diff except you don&#x27;t need the full source of the original base?

Maybe you can put a small example of code changes that illustrates this. The diagram helps but actual output based on a toy example would drive it home, I think.

I&#x27;m the author of DiffLens (<a href="https:&#x2F;&#x2F;www.difflens.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.difflens.com&#x2F;</a>). I initially built it for myself too (and use it everyday) and it&#x27;s currently free for anyone to try. It&#x27;s an attempt to use abstract syntax trees to make diffs more readable. Happy to see another diff project here!

This seems very similar to the &quot;second-order diff&quot; trick: <a href="https:&#x2F;&#x2F;blog.moertel.com&#x2F;posts&#x2F;2013-02-18-git-second-order-diff.html" rel="nofollow">https:&#x2F;&#x2F;blog.moertel.com&#x2F;posts&#x2F;2013-02-18-git-second-order-d...</a>

i haven&#x27;t used git range-diff but when local master is behind origin&#x2F;master and I am trying to diff, I use a `git changes` .gitconfig alias:<pre><code> changes = !git diff $(git merge-base HEAD \&quot;$REVIEW_BASE\&quot;)
</code></pre>
Typically, that&#x27;s:<pre><code> git diff $(git merge-base HEAD origin&#x2F;master)</code></pre>

A tool called &quot;diff modulo base&quot;: <a href="https:&#x2F;&#x2F;git.sr.ht&#x2F;~nhaehnle&#x2F;diff-modulo-base" rel="nofollow">https:&#x2F;&#x2F;git.sr.ht&#x2F;~nhaehnle&#x2F;diff-modulo-base</a>Given two version (old and new) of a Git change (i.e., individual commit or patch series from a pull request) it produces a diff that is actually useful for reviewing purposes, assuming you&#x27;ve already reviewed the old version of the change.It&#x27;s sort of like `git range-diff`, but where `git range-diff` produces a &quot;diff of diffs&quot; that is very hard to impossible to read, this tool gives you a direct diff between old and new versions, but filters out any irrelevant changes that were introduced because the author rebased on a more recent version of the target branch.I hope that makes sense - I never know quite how to put it into words for somebody to understand who isn&#x27;t intimately familiar with Git. It is very powerful though if you combine it with a minimal amount of setup e.g. for fetching all PR branches from a GitHub repository. I use it almost daily as part of my code review workflow.

yep, that was the goal. my friend had a small organic farm but he lived an hour away and needed a good, cheap watering solution. led me to down a rabbit hole and now i&#x27;m a software developer. i&#x27;ll probably revive it once i have some space to do more serious vegetable growing

Geeky misconception: the wet&#x2F;dry cycle can be optimal.

Be nice to hook that up to some kind of watering system to always have the perfect moisture.

a soil moisture sensor using capacitors as the sensor. it&#x27;s how i learned to code. i found a few different versions of the project online. couldn&#x27;t get them to work very well but i was able to piece together enough knowledge of basic circuits to get the sensor to work well with my own circuit design.once i got it to work, i left it on my desk for a few months and then cleaned it up&#x2F;removed the circuit. only documented the circuit by a couple of bad photographs, so i&#x27;m not sure how to recreate it. i might could figure it out again if i spent the time, but i&#x27;ve been focused on other projects.<a href="https:&#x2F;&#x2F;github.com&#x2F;smcalilly&#x2F;sensor">https:&#x2F;&#x2F;github.com&#x2F;smcalilly&#x2F;sensor</a>

Alright, i&#x27;m buying a paramotor. Thanks a lot.

<a href="https:&#x2F;&#x2F;ppg.report" rel="nofollow">https:&#x2F;&#x2F;ppg.report</a>Shows a nicely formatted weather report for flying my paramotor, pulling data in from many different sources :-)

&gt; But because it doesn&#x27;t support a way to run local apps that fetch from APIs, I had to add a way to show the forecast for other spots and make it &quot;official&quot;.I’m having difficulty parsing and understanding this sentence: how did this result in your display being posted on instagram without your knowing?

I bought one of these LED screens (you get 64*32px, so not a lot!), and I wrote an app to view my local surf conditions on it (so I know what I&#x27;m missing out on while working). But because it doesn&#x27;t support a way to run local apps that fetch from APIs, I had to add a way to show the forecast for other spots and make it &quot;official&quot;. No idea how many people use it, but I saw it on instagram ads so that was some kind of validation haha. It looks like this: <a href="https:&#x2F;&#x2F;pbs.twimg.com&#x2F;media&#x2F;FMi996lVIAAQMI3?format=jpg&amp;name=medium" rel="nofollow">https:&#x2F;&#x2F;pbs.twimg.com&#x2F;media&#x2F;FMi996lVIAAQMI3?format=jpg&amp;name=...</a>

It should exist and would be super powerful considering all the recent advancements in language ML. Here was the mental model of my model: the canonical representation (i.e. a representation after taking out run-time populated fields) of a log line represents the smallest meaningful unit of this &quot;log language&quot;: _a word_. Taking this analogy further, an event is a collection of logs that occur together (mostly in order)—just like words spoken together form _a sentence_. Finally, collections of events that occur in close proximity (in time) represent _paragraphs_, while paragraphs occurring in a certain order constitute _chapters_. Using this mental model opens the door to apply all the new AI techniques for text extraction, summarization and generation to extract the semantic structure of any &quot;log language&quot; and then learn and classify behaviors observed at run-time. The eventual objective function is not generation though--it&#x27;s reasoning with the optimal FP-TP tradeoff on a ROC curve.I haven&#x27;t seen anyone do it yet. Maybe companies like Splunk and Elastic will take a lead here. I am happy to engage, advise and contribute if there is an open source project around this.
Has anyone else seen something remotely close to this?

&gt;This is way before all the LLM and Generator models, but it was such a fun project.That means something more sophisticated has to exist today and should be commercially available. Can anyone explain to what extent companies use this stuff in their interaction with customers, and how successful is it? (Somehow I still see AI still as one-off things people do for fun or AI being used to hype up rather mundane software.)

Don&#x27;t think I quite follow. Is the new program (operating on the output of the earlier program) supposed to reason about why you are seeing the result that you are seeing? Or is it doing more post processing to make the earlier output directly consumable by your corporate systems.

We have a corpus or database of programs that follow logic but with no simulation, so it represents knowledge to solve a problem yet all we have control over is the parameters (inputs). In this case, input is functional logical content (a program), describing the resolution of corpus details. The model solves its integrated, corporate logic, and our output is an interpretation of that individual program.Now our task is to swap out this entire database for something like it, but not exactly the same. The output becomes the input to this new matrix. The individual program persists, but everything is the next generation. With a little book-keeping, the programs do our will...

There&#x27;s a YC startup that&#x27;s doing something along these lines. They recently posted something, don&#x27;t remember if it was on front page or an &quot;YC startup jobs&quot; email.

About 8 years back, I was leading an engineering team which was the escalation path for customer support. We were sitting on a large corpus of support tickets but didn&#x27;t have any insights. I was amazed when word2vec came out and blew my mind. So I built a language model that trained on support ticket data. I modeled system logs attached to support tickets as an NLP model to predict what was going to fail next and for which customer.Never made it to prod but was a great tool for me to see where I want to budget my team&#x27;s time.This is way before all the LLM and Generator models, but it was such a fun project.

Awesome! I hope you make this public one day.

in lieu of making it public, publish a table of timestamped youtube links

I&#x27;m a big SNL nerd and have favorite sketches&#x2F;memories going back over 30 years. I find it very rewatchable, but streaming services don&#x27;t have full episodes, and even downloading full episodes wouldn&#x27;t make it easy to find individual sketches. So I built a Plex library of over 500 individual sketches using some automation.I used yt-dlp to download the metadata for over 6,000 videos on the SNL Youtube channel. I put it into a database, parsing out season&#x2F;episode into fields where possible. Then I wrote a small Flask app to search or browse seasons&#x2F;episodes, from which I could flag for download the sketches I wanted.

A “note taking” app after spending years looking for “the right one”. Nothing ground breaking, similar to most other “connected notes” apps but with one small difference: everything is built for my brain workflow rather than the other way around.<a href="https:&#x2F;&#x2F;nvartolomei.com&#x2F;omniverse&#x2F;" rel="nofollow">https:&#x2F;&#x2F;nvartolomei.com&#x2F;omniverse&#x2F;</a>Maybe, one day, after I’m satisfied with its functionality I’ll make it open(-source). For now, in the interest of keeping friction low, moving fast and breaking things, it’s pretty private.

That&#x27;s smart, and there&#x27;s so many very simple ways I could go about implementing that. Nice one, I might give that a go.

I&#x27;ve tried things like this but my future self feels zero allegiance to what my past self wanted it to read.

I really like reading books, non-fiction, fiction, business, everything. But I always tended to have good reading momentum and then life&#x2F;work happened that derailed the reading habit - and I forgot about it. Took months to pick up again...To keep reading top of mind I built a Chrome &quot;newtab&quot; extension to show my &quot;Currently Reading&quot; list, and excites me about books I&#x27;ve put as &quot;to-read&quot;. It has worked wonders on my reading! And it is pretty small and polished - no tracking, no credentials, just bare-bones.<a href="https:&#x2F;&#x2F;chrome.google.com&#x2F;webstore&#x2F;detail&#x2F;currently-reading&#x2F;fgbnpcnlpefbnbgbdfemhbbcnamdmepk" rel="nofollow">https:&#x2F;&#x2F;chrome.google.com&#x2F;webstore&#x2F;detail&#x2F;currently-reading&#x2F;...</a>

RGB room lights controlled via Arduino with a companion mobile app for changing colors&#x2F;modes. Used zeroconf for finding the device on the network.

I built a cloud for my family to use.It leverages containers and Docker Compose, mainly for it&#x27;s tooling that makes it easy to deploy. I made a tool that correctly selects the right node based on the directory I&#x27;m in using Docker Profiles. The networking is both internal and external; I share some APIs externally, like to share photos or to run video game servers, while other services are entirely privileged. It, for the most part, implements mTLS, and has both public and private DNS. I have a single ingress node in my cloud provider that is connected to my home servers via Tailscale. It&#x27;s been instrumental in building out things at my house and making my life easier and cheaper.

worked for about a week on very specific brokers. Then they started slipping my trades. Slippage became a big issue. I still can&#x27;t fathom why such a thing is legal

a sub-ms trading platform written in Rust to try and do arbitrage across multiple FX brokers.

I built a pretty simple command line application (glorified python script) years ago that sends messages into a specified matrix room, and intended for use as a basic server notification system. Only recently posted to github (because a friend asked me to share); see: <a href="https:&#x2F;&#x2F;github.com&#x2F;mxuribe&#x2F;howler">https:&#x2F;&#x2F;github.com&#x2F;mxuribe&#x2F;howler</a>Like other sys admins and devs, I had used email notifications for years to notify me whenever *stuff happens* on a server (like a job ran&#x2F;completed, some storage device is low, etc.). But when matrix came out several years ago, i really liked the concept, became a bit of a matrix fanboy, and built a little script to leverage - nowadays, all of - my server notifications. Again, pretty basic&#x2F;not sophisticated, but it scratches my itches.

* When RSS was a thing but in my country a lot of news&#x2F;content websites hadn&#x27;t adopted yet, I wrote a service to quickly define scrapers that turn those sites into RSS feeds.* In one of my former workplaces I wrote (alongside another person) a gamified shared playlist app that allowed everyone to participate in being a DJ for our company hackathon (people getting more upvotes getting more playtime, songs getting many downvoted being skipped in the middle, etc). That was a lot of fun and surprisingly a very emotionally engaging experience for everyone.

If you build for yourself, you never lose.

perfect example of how to say you are the founder without saying you are the founder?

The first build of DemoTime was for myself. Obviously it no longer is.

A cheaper form of therapy. Therapists are mostly mirroring your own thoughts or helping you see things you can&#x27;t see. Ideally you have something that can just listen and echo your thoughts back or acknowledge them, without the need to pay $100&#x2F;hour.

Out of curiosity, what do you hope the AI will do with your thoughts?

Lots of things. But one I am coming back to is called Malten (<a href="https:&#x2F;&#x2F;malten.com" rel="nofollow">https:&#x2F;&#x2F;malten.com</a>). It was essentially a place for me to blackhole my thoughts anonymously rather than putting them on twitter. Recently as I&#x27;ve seen ChatGPT take off it&#x27;s made me revisit the project and create an integration for it (not yet publicly hosted). Ideally I&#x27;d just be able to voice my thoughts to an AI now in a private manner. Let&#x27;s see.<a href="https:&#x2F;&#x2F;github.com&#x2F;asim&#x2F;malten">https:&#x2F;&#x2F;github.com&#x2F;asim&#x2F;malten</a> for anyone who wants to run it themselves.

I think all of Canada would be interested.

My ISP is total crap and charges a fortune for a miserable service that at this point should be nationalized, and I&#x27;m not a radical communist either. Anyway, I need to monitor my usage and the interface they provide is a dumpster fire so I created the most spectacular Rube Goldberg abstraction to get access to all my past data using damn epoch timestamps and a data scrapper and now I can forecast my usage, set SMS alerts, get usage on a Telegram bot and access all my data via API. I think other people might want to use it but I&#x27;ve always been too busy to polish the product for an audience.

Probably boring to most people but I created a tool to nail exactly 40 hours a week contracting using the laziest possible inputs getting me out as early as possible on Friday:<a href="https:&#x2F;&#x2F;github.com&#x2F;cynoclast&#x2F;time">https:&#x2F;&#x2F;github.com&#x2F;cynoclast&#x2F;time</a>Usage example:tm 8.5 9.27 8.83 8.87 9:45-1:23 1:33-14:1154 minutesNotice you don&#x27;t have to give it AM&#x2F;PM? Also don&#x27;t have to give it any flags. It figures out what to calculate based on number of arguments alone. And it knows 9:45 to 1:23 is around 4 hours, not -8.And during the week, decimal hours for timesheets:tm 8:30-12:30 12:40-6:4010.0I used it 5x a week during my contracting days.

Wow.I&#x27;ve often wanted a 3d grid for exploring alternate tunings, which would only be feasible in VR. (On the other hand, since buying a Lumatone hex-grid keyboard last year, not so much.)

I built a VR environment for making and thinking about music, intuitively playing with alternate tuning systems, building instruments in space and livestreaming.<a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;live&#x2F;v4uHqdTr-bs?feature=share&amp;t=4263">https:&#x2F;&#x2F;www.youtube.com&#x2F;live&#x2F;v4uHqdTr-bs?feature=share&amp;t=426...</a>There are a few simple but powerful building blocks. One main feature is an egg shaped &quot;note&quot; which can be placed, resized, retuned and cloned on the fly. It&#x27;s played by physics interactions with a &quot;mallet&quot; or sports balls, anything with a collider.One of the instruments is a sine wave organ which has drawbars to control the amplitude of overtones. Unlike a classic organ, these overtones can be independently retuned and assigned envelopes to produce a range of timbres. Pitch is consistently mapped to a spiral - an isomorphism of pitch space.It has a theremin which provides visual and tactile feedback and a voice with vocal formants controllable with a thumbstick.It has a physics based sequencer of sorts which consists of &quot;mallets&quot; on a wheel which spins at a desired ratio of whatever BPM is set in a DAW. These wheels can be cloned and multiple mallets arranged around the circle using the Euclidean rhythm algorithm.Since low latency audio in Unity is tricky, the VR app is really just a controller for synthesizers running in Max&#x2F;MSP and IEM spatial audio VSTs running in REAPER. One day I&#x27;d like to package some portion of it into a mobile VR app for things like remote jamming or music lessons where models of the theoretic ideas are right there in front of us to tinker with. For now, it&#x27;s just for me.

I built some groundbreaking technology to make it easier to browse torrents on the RARBG website.<a href="https:&#x2F;&#x2F;greasyfork.org&#x2F;en&#x2F;scripts&#x2F;36751-rarbg" rel="nofollow">https:&#x2F;&#x2F;greasyfork.org&#x2F;en&#x2F;scripts&#x2F;36751-rarbg</a>

Nice setup! I was about to start ordering parts to create some hacky IR sensor for mine, that it before I read about HDMI-CEC.

Eh, at the moment a universal remote control app for my home theater. I expanded it somewhat for many other devices than I need, for friends and people on the AVSForums who requested things.<a href="https:&#x2F;&#x2F;github.com&#x2F;nicko88&#x2F;HTWebRemote">https:&#x2F;&#x2F;github.com&#x2F;nicko88&#x2F;HTWebRemote</a>It&#x27;s not all that impressive per say, but a number of people seem to really like it.Also an app to add a &quot;wind&quot; effect to a home theater as well.<a href="https:&#x2F;&#x2F;github.com&#x2F;nicko88&#x2F;HTFanControl">https:&#x2F;&#x2F;github.com&#x2F;nicko88&#x2F;HTFanControl</a>

I wrote a few things I use all the time.1. A youtube bookmark manager for Emacs using Sqlite as a back end.
 - You can keep track of individual videos.
 - Manage series that span multiple videos.
 - remember interesting moments.2. A system to help manage my finances by tracking what percent of my assets are in a given category. This helps with maintaining, say, a 60%-40% stock vs bond split across multiple financial institutions.

Which part? The glass is an Epson BT-40 cut in half with some soldering to bypass needing both eyepieces; this cuts the weight &amp; power consumption by ~40%. Mounted onto a printed carbon-fiber nylon frame similar to bone conduction headphones. The computer is a single-board computer I had lying around, but I will upgrade to 12-core 30W SBC next week. The battery is one made for video cameras, and I gave it a belt clip and strapped the SBC onto it. The SBC has camera &amp; mic inputs as well as GPIO for whatever I want to add.

Care to share more details on how you&#x27;re achieving that?

A custom, DIY smart monocle from off-the-shelf parts, 3d printing, and custom electronics: 1080p60hz, 8-11hrs of battery life on a belt-clip battery + computer combo, has wifi &amp; lte&#x2F;cellular, can run ML models on device. One third the weight of upcoming Apple AR&#x2F;VR glasses and one-sixth the cost. Just having it working has increased my efficiency a ton without obstructing vision or requiring me to look at secondary monitors or phone.Working on replacing my wireless keyboard and trackpad with some &quot;gloves&quot; so I can use it while on hikes or just generally outside. Then, gonna integrate some custom AR and ML&#x2F;GPT.

This is wonderful, and fast too (because it’s static I guess)! Thanks for building it. I’ll be checking it when I need some inspirational quotes surrounding a word.

Sometimes I know that a precise word for what I want to say exists, and I&#x27;ll know it when I see it, but I can&#x27;t quite remember it in the moment. In those cases I search thesaurus for synonyms to related words; or maybe ask ChatGPT these days.

I don&#x27;t particularly care about synonyms (when I consulted a thesaurus too much my writing became too flowery) but the historical quotes feature was just great! I can imagine downloading the full text of several of my favorite authors and index the words from that corpus.

Slightly similarly, I made a searchable word list to help with doing or compiling puzzles: <a href="https:&#x2F;&#x2F;jawj.github.io&#x2F;wordtools&#x2F;" rel="nofollow">https:&#x2F;&#x2F;jawj.github.io&#x2F;wordtools&#x2F;</a> (the ‘anagrams’ link does nothing yet).

this is lovely!! neat, clean and useful. I&#x27;m gonna use it, thanks for making it!

This is really cool!
Could you please add a keyboard shortcut for focusing the input field? (perhaps a forward slash &#x27;&#x2F;&#x27; like on Youtube or Github)

This is awesome! I&#x27;ll definitely use it.It&#x27;d be a one time stop for me if it supported definitions (similar to Collins Dictionary) but beggars can&#x27;t be choosers.

I like it, especially the quotes. Reminds me of linguee.fr, which I use often while learning French.

Onelook is incredible. Indispensable for any art of writing.

It&#x27;s worth noting the best thesaurus I&#x27;ve found is onelook. Compare to the solitude results<a href="https:&#x2F;&#x2F;onelook.com&#x2F;thesaurus&#x2F;?s=solitude" rel="nofollow">https:&#x2F;&#x2F;onelook.com&#x2F;thesaurus&#x2F;?s=solitude</a>This is by datamuse who also does rhymezone (<a href="https:&#x2F;&#x2F;datamuse.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;datamuse.com&#x2F;</a>)

I built carefulwords.com simply because I wanted to type a word into the address bar and get a large list of synonyms and some historical quotes using the word quickly. For example:<a href="https:&#x2F;&#x2F;carefulwords.com&#x2F;solitude" rel="nofollow">https:&#x2F;&#x2F;carefulwords.com&#x2F;solitude</a><a href="https:&#x2F;&#x2F;carefulwords.com&#x2F;think" rel="nofollow">https:&#x2F;&#x2F;carefulwords.com&#x2F;think</a>etc. Also unlike thesaurus.com, the search bar actually focuses so you can just start typing!It&#x27;s not perfect, I need to do a lot of editing, but nonetheless I use it almost every time I write, now.The site is a little over 30,000 static HTML pages built with a number of TypeScript scripts that compile some sources for synonyms, parts of speech, and the quotes.

Old School Runescape recently released a feature called &quot;group ironman&quot; that lets you play the game while only being able to trade with or assist others in your small &gt;=5 man group. I made a small service that periodically scrapes the game&#x27;s hiscore data and generate reports and metrics about the group&#x27;s progress. And then a Discord bot to interact with the service

In 2011 and 2012 in between jobs I wrote a few bits of software, of which- one was a SQLite3-based, all-SQL reimplementation of a subset of UName*It (an object-oriented database from the 90s meant for storing NIS&#x2F;DNS&#x2F;etc. data)- another was an RCU-like lock-less, very fast user-space data structure written in C, born of frustration with read-write locks in SolarisOf those the latter ended up being useful to me about 5 years later, and I still use it in production, though I originally wrote it for myself.

Over the past 3 years, I&#x27;ve been building &quot;FreeCRT&quot;, a 24&#x2F;7 Twitch streaming setup dedicated to casual Smash matches. Since I don&#x27;t have a coding background, I used Node-RED to create custom flows that help manage the stream by connecting a MSI Gaming Laptop, Intel NUC, and Raspberry Pi 4. OCR and Node-RED extract text from the switch, while performing arena error logic, which connects to the Raspberry Pi to run macros to reset the open arena if it&#x27;s closed. I just recently whipped up a Twitch Chatbot called FreeGPT that hosts the arena anytime. I&#x27;ve built it up slowly but it&#x27;s been such a fun long term project.

haha I&#x27;ve had uICAL in a tab open for a week now, anticipating the plunge. ty for the experience :) guess i&#x27;ll just hack the parser myself...I&#x27;m also on esp32, and have been wanting to write more using the native esp-idf tooling.

But I had too many messups with that)FWIW, Google Calendar recently stopped including real Timezone information in the calendar urls for newly created calendars. I ended up doing something gross to manage that (got a dump of all the tzurl &#x27;outlook&#x27; calendar files, and load that before loading the user calendar; it&#x27;s sketchy, but it works)

I made a small 4 digit LED display that syncs to my work calendar and counts down the hours&#x2F;minutes or minutes&#x2F;seconds to my next meeting, depending on how close it is to starting.Currently working on moving the ICS calendar parsing part from a python script down to the microcontroller itself, then I can release.

I have a music playlist program which deals with the problem of getting used to music. It&#x27;s effective because I seldom want to choose a track to play, and I don&#x27;t find myself skipping a lot consecutively.I have a dedicated key for skipping (and I keep adding meta keys to make it skip more (each meta key is x2)). The next track to play is automatically selected based on the combination of two factors: being skipped less and being played less.I get to hear my whole collection in a way that&#x27;s far more enjoyable than an unweighted shuffle.

Everything I do is emacs. But I&#x27;m not sure which sense you&#x27;re asking about.(HN isn&#x27;t emacs, though. pg uses vi.)

There&#x27;s a bunch of secret stuff in it, in the sense of moderator-only.I don&#x27;t think there&#x27;s anything sinister, but it wouldn&#x27;t be very nice to release in the current form.

Maybe you’re overthinking it? Just push it to GitHub and call it a day. Someone else will turn it into the general-reader version.Unless it has a bunch of secret stuff in it. Then I guess you’d have to.Don’t underestimate the tenacity of HN readers though. Lots of us would do that kind of thing just for fun. You don’t have to do it all yourself.

&gt; • Fix Cloudflare “[email protected]” stupidity without having to run the page’s arbitrary JavaScript. (Basically: take their deobfuscator script and just run it myself if it gets used. Only people that deliberately block JavaScript are likely to have seen this, but it’s quite common. The filter they use is evidently very dumb, obfuscating quite a few things that are not email addresses, including things like “package-name@1.2.3” (not even valid—IP address hosts have to be in square brackets, and DNS doesn’t use numeric TLDs) and “user@host” in console logs.)&gt; • Hold z to make a currently-playing audio or video go at 4× (the fastest you can go before Firefox cuts off the audio).Are these open-source by any chance?

Ah, browser extensions and user scripts are so great for improving websites.Most of my current user scripts:• Hold z to make a currently-playing audio or video go at 4× (the fastest you can go before Firefox cuts off the audio).• Auto-admit in Google Meet (wish they’d implement this themselves). There were a couple of browser extensions to do that, but I looked at their source and was appalled at how badly and&#x2F;or stupidly they implemented it, and so wrote this, which is better (… so long as you use English—one of them supported I think it was Japanese as well) and more efficient: new MutationObserver(() =&gt; { document.querySelector(&quot;[aria-modal=&#x27;true&#x27;][aria-label*=&#x27;join&#x27;] [data-mdc-dialog-action=&#x27;accept&#x27;]&quot;)?.click(); }).observe(document.body, { childList: true, subtree: true });• Retitle a few web apps that have consistently useless document titles, by pulling in actual document contents. I gave this to my sister, who regularly has hundreds of VicFlora tabs open, which used to be all titled “VicFlora”; last year they fixed that but got the endianness wrong, “VicFlora – ‹Page title›”, so I fixed that to “‹Page title› – VicFlora” so you can actually see the useful part in the tab bar. (Document titles should be little-endian.)• Find &lt;video autoplay&gt; and turn on controls (since I have autoplay blocked—incidentally, this is something disabling autoplay should probably automatically do, at least until you start the video).• Kill aos-* animations on pages, which stupidly tend to make the page invisible until their JavaScript loads. (This is important for me because I disable JavaScript, but those “fade in when the page loads or as you scroll” animations are really annoying even when they work, killing them makes things better.)• Fix Cloudflare “[email protected]” stupidity without having to run the page’s arbitrary JavaScript. (Basically: take their deobfuscator script and just run it myself if it gets used. Only people that deliberately block JavaScript are likely to have seen this, but it’s quite common. The filter they use is evidently very dumb, obfuscating quite a few things that are not email addresses, including things like “package-name@1.2.3” (not even valid—IP address hosts have to be in square brackets, and DNS doesn’t use numeric TLDs) and “user@host” in console logs.)• Put the current weather into the favicon on weather.bom.gov.au (… except that they this shut down last month for no obvious reason, with no equivalent replacement unless you run Google Android 6+ or iOS, which I don’t on any device, let alone my laptop; so I’m stuck with just their old site which completely lacks a lot of the information this other thing had exposed, and is served over HTTP only but their server accepts HTTPS connections in order to 307 redirect to a different path on http: scheme as well in order to say “we don’t support HTTPS”, which interacts horribly with “HTTPS Only” mode (because even when you add an exception for the duration of the session, you lose the path part of the URL), and is the only site I’ve ever encountered doing such a stupid thing, and in all this they have never responded to my enquiries like they claim they will).

&gt; It requires a keyboard, though. Do the kids still use those?I&#x27;m sure your server logs will tell you what percentage of visitors are NOT mobile.

Definitely my HN moderation browser extension, which lets me flip through HN super fast and do routine mod tasks without gruntwork.If I live long enough, I will factor out a general-reader version of this that will bring joy to HN power users everywhere.It requires a keyboard, though.

I love this idea! Thanks for sharing, I&#x27;m looking forward to trying this out day to day.

This is great!I’ve always wished for a replacement Spotify UI that’s entirely album focused.

not sure how interesting but definitely useful :D I like to listen to Albums and I missed the &quot;Give me a random album from my collection&quot; functionality in Spotify so built a tiny webapp to do exactly that - <a href="https:&#x2F;&#x2F;shuffle.ninja" rel="nofollow">https:&#x2F;&#x2F;shuffle.ninja</a>.It uses the Spotify web APIs to fetch your album collection and gives back a random album from it. I use it daily.

I was playing a MMO with a market. Sometimes people would make mistakes, e.g. selling 100 iron for $1,000,000 instead of selling 1,000,000 iron for $100. I made a little tool that polls the API and sends a notification when someone made a mistake.Eventually I got bored of grabbing these mistakes and left the tool with my clan. It had the side effect of getting people active on Discord, and making people more actively involved in countering raids. We ended up building one of the most elite clans in the game until some other whiz kid built a better bot.There was also this little augmented browser tool that calculates the best order and timing to attack in the game, and the statistically likely result.We&#x27;d joke that all the tools we built for that game were probably well worth hundreds of thousands of dollars and that&#x27;s around the time I decided to quit and spend my time on something more useful.

As it happens, I just built the minimal, hackable tool for drawing boxes and arrows that I&#x27;ve always wanted.<a href="https:&#x2F;&#x2F;git.sr.ht&#x2F;~akkartik&#x2F;snap.love" rel="nofollow">https:&#x2F;&#x2F;git.sr.ht&#x2F;~akkartik&#x2F;snap.love</a>

You&#x27;re right, it&#x27;s the latter. Yeah, you can still use the keypad after the call is started. But it&#x27;s a little clunky. The instructions you have to give people are like &quot;first dial 542, then wait until you hear the prompt, then enter code 867&quot;. Which as it turns out is a little too complex for a lot of people. Another reason why it wouldn&#x27;t have been great as a paid product.You could also have a fallback that forwards the call to your cell phone after a failed attempt at entering the code. But most of the reason I built this was so it would stop calling me at random times, so I didn&#x27;t really want that.

That sounds neat. When you say everyone got their own code, do you mean that each person had a separate code for the call box, and the call box would call one of many separate Twilio phone numbers? Or did the call box always call the same Twilio number, and you instructed each person to then input their special code via the call box? My apartments have always just asked me for a single phone number which they program into the call box, so I’m guessing the latter, although it never occurred to me that the guest might be able to press more buttons after the phone call has been connected.

You&#x27;re right, this looks like almost exactly the product I would have made if I decided to turn it into a product. I think they started around the same time I did. I wonder how much money they&#x27;re making on it? Could be a nice little lifestyle business if they get enough users. I bet their Airbnb-focused features would be the real moneymaker, I didn&#x27;t consider that as a potential market.

I think FreshBuzzer is a similar idea: <a href="https:&#x2F;&#x2F;freshbuzzer.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;freshbuzzer.com&#x2F;</a>

Nice! I built the same thing for a gate at our vacation house at a lake. The home-owners have to register their mobile number so that if you call a certain number the gate opens based on number recognition. Every time new people were at the gate (deliveries, guests, renters) they would need to call the owner, who had to hang up and call the gate’s number.I use twilio to make outbound calls to that number using my registered phonenumber. I put a Django app in front for home owners so they can add authorized phone numbers with a expiration date.Whenever someone is a the gate they call a twilio number, my django app checks the validity, opens the gate by calling the gate’s number with my number as ID, plays back some welcome message “hello chris, welcome to…” and sends the owner a push notification that person X is en route.Todo: add a feature to redirect an unknown number directly to the owner and open the gate after manual verification.

Cool. I did the same thing for my office building except I had Twilio post to our work slack with buttons that we could click to let them in or not. It was a really fun little afternoon project one day.

That&#x27;s right. And simultaneously send a text like &quot;FedEx opened the gate&quot; or &quot;Doordash failed to open the gate after hours&quot; to my and my wife&#x27;s phones.

How did this work exactly? Twilio would answer the call, listen for a number, and &quot;press&quot; 9 if the number was in an allow list?

&gt; With triggers like: If the cleaner is more than 15 min late 5 times in a period of 3 months and there are more than 5 resumes posted for cleaning positions do not open the door and fire them.I hope what you’re describing never becomes a reality. People aren’t disposable tissues for your convenience.

The product should be a LLM learning from each interaction globally. So you walk up to the door and it says Hello Jim, I see you work for fedex now. Could you please show me the label on the package?With triggers like: If the cleaner is more than 15 min late 5 times in a period of 3 months and there are more than 5 resumes posted for cleaning positions do not open the door and fire them.

Haha, I also built exactly this!I had mine integrated with Home Assistant and got notifications via a telegram integration.I also had mine setup so me or my room-mate in our apartment telegram group could register new codes, or generate single-use codes.I also considered building it into a paid app, but came to the same conclusion :-)

I used to have this when I lived in Seattle! It’s pretty cool tech

ButterflyMX is used a lot in Seattle buildings and does quite a bit similar to that: <a href="https:&#x2F;&#x2F;butterflymx.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;butterflymx.com&#x2F;</a>

You could do that through Slack or Home Assistant too. Nice work, you’ve given me a few ideas.

My related story: we have door phone system in our apartment house and I wanted to get a notification whenever our flat got buzzed. I hacked the phone in our flat - attached a circuit directly to the wires leading to the coil of the buzzer and through arduino to the pc. Then I stitched together some code utilizing firebase to send notifications. Worked like a charm until google began to require credit cards for the free stuff.

I made something similar for an old nyc apartment intercom buzzer.Also
Hooked it up to Twilio so I could text a number and it would let me in.Added passwords and such so I could share it with friends.

I had a buzzer that was basically a button on the handset of a phone which would
Open the door, I wasn’t allowed to open it up to wire directly into it so I slapped together a node red script on a rpi with a servo that would push the button to buzz open the door anytime I said “open seasame” with Siri via an iOS automation thingy. Never needed to carry keys again while we lived there.

That’s actually some very cool hacking together! Love it.

No code actually, I made it all in Twilio Studio which is their visual programming &quot;no-code&quot; tool for phone trees. Clunky to work with but trivial to set up and had enough functionality for this very simple application.Obviously to make a real app out of it I would have redone it in a real programming language and made some frontends for web&#x2F;Android&#x2F;iOS.Someone else pointed out <a href="https:&#x2F;&#x2F;freshbuzzer.com" rel="nofollow">https:&#x2F;&#x2F;freshbuzzer.com</a> which looks like a real product that does the same thing.

That sounds like a fantastic tool. You didn’t happen to open source any of your efforts did you? I’m planning to do something like this and any head start would be greatly appreciated.

I imagined standing there calling you to open my door but it seems an interesting security feature. You could even have a second front door and trap people. When one leaves they have to close the living room door before opening the front door. Say someone walks you up to your door at gun point to rob you or they attempt to force their way in. You can just tell them you cant prevent the call to the police and that the door wont open, we will be trapped in the hallway, I have no control over it.

Hah, I also built this for myself, and also considering productizing it, except I realized that there&#x27;s absolutely no way I want to be responsible for the situation where my service is down and people cannot get into their houses.

My townhome complex had one of those call boxes at the front gate. When Doordash&#x2F;FedEx&#x2F;the cleaners&#x2F;the in-laws&#x2F;etc arrived they would have to call me from the call box and I&#x27;d have to answer it and listen to garbled audio to figure out who it was and press 9 to open the gate. It was kind of a pain, so I made a Twilio app to answer calls from the call box.I set up custom entry codes that I could hand out to anyone. Everyone got their own code, and it would text me whenever someone used a code so I&#x27;d instantly know who was coming. The text conversation was my timestamped access log. I also put time constraints on some codes so e.g. Doordash couldn&#x27;t open the gate in the middle of the night, or I could set up a temporary access code for a party, and I rotated codes too, with text notifications if an outdated code was used.I thought about making a paid app out of it, but it just didn&#x27;t seem worthwhile. I didn&#x27;t expect that many people would want to pay for it. For a while I was excited about a YC startup called Doorport that was going to make a hardware device that you&#x27;d install inside those dumb call boxes and make them smart with all sorts of cool features, better than my Twilio hack. But I think they pivoted to a much less interesting pure software thing and then got acquihired.

I built a cross of React + Wiz (a fantastic frontend framework at Google): <a href="https:&#x2F;&#x2F;github.com&#x2F;aschleck&#x2F;trailcatalog&#x2F;tree&#x2F;main&#x2F;js&#x2F;corgi">https:&#x2F;&#x2F;github.com&#x2F;aschleck&#x2F;trailcatalog&#x2F;tree&#x2F;main&#x2F;js&#x2F;corgi</a> . Totally irresponsible and probably full of bugs, but I was so tired of writing business logic in the same place as my view logic with React and now I&#x27;m free of it!

You still got this? I&#x27;d love to use it myself.

Great idea! Would love to give the script a spin myself..

Scott’s cheap flights (going.com now) has basically implemented this in a nice little paid service. I got sub-$400 roundtrip direct from Seattle to Dublin. If you can snag even just a deal a year, it’s well worth the small yearly price!

I know that you don&#x27;t want when more competition for the flights, but that sounds very useful!

Been traveling a lot this year - this would&#x27;ve saved me a ton of money. If you&#x27;ve still got the script lying around, I&#x27;d love to check it out

I don&#x27;t know if it qualifies as the &quot;most interesting&quot; but as a travel bug I wrote a little airfare scraper that I got plenty of value out of.Basically it&#x27;s a script that scrapes several places for flight deals and &quot;mistake fares&quot; and notifies my phone if it matches with my city. No searching like other flight apps, you basically just set it up and wait, and various places will pop up. Helps if you&#x27;re in a hub city e.g. NYC.The phone notification was crucial because such deals sold really fast. In case the booking didn&#x27;t work out I was usually covered by the 24 hour cancellation rule [0][1].I started off running it on my own server but later I learned IFTTT handles device notifications without paying the Apple Developer tax, so I migrated things there. Used it more when I was single but nevertheless it&#x27;s helped me land some killer deals e.g. NYC-Dublin RT for $300, NYC-Paris RT for ~$400.Thought about making a paid app out of it but the limited seating and time-sensitive nature of these deals is tricky.[0] <a href="https:&#x2F;&#x2F;www.transportation.gov&#x2F;airconsumer&#x2F;notice-24hour-reservation" rel="nofollow">https:&#x2F;&#x2F;www.transportation.gov&#x2F;airconsumer&#x2F;notice-24hour-res...</a>[1] I believe this rule, which is not so broadly known, was imposed on air carriers in response to certain fraudulent online marketing practices going on at the time.

Not really sophisticated but I wrote a ~200 line Python script to trawl a few data sources like USPTO and Reddit and aggregate that info into an e-mail for me to review daily.  It was extremely helpful in getting me up to speed in a new job that I lacked the background for.

No, I&#x27;m a game developer. The app I&#x27;m making is a web app that I don&#x27;t have much experience with. I&#x27;m using ChatGPT as a tool to cut down coding time and it is working great so far. I should have worded my comment better.

I&#x27;m using ChatGPT to build a note taking app just for myself. Haven&#x27;t completed it yet but plan to open source it once it is done.

The most interesting tech I made for myself is rather mundane, but it&#x27;s one I use every day, it&#x27;s the FinalKey password manager.

Maybe you&#x27;ve created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you&#x27;ve built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I&#x27;d love to hear it.

Ask HN: Most interesting tech you built for just yourself?
