Local golang work with docker but mostly as a dumb terminal interfacing with a remote k8s cluster and using the web as a reference.

Yes, but you&#x27;re running off a sloooow sd card which may slow you down a bit if you compile stuff.Other than that it&#x27;s just a normal linux computer.Mind, I&#x27;ve only done command line and text mode editors, if you want the full desktop and a ram hungry IDE it&#x27;s going to hurt more.

I use a Pi3B+ for dev at home (working on nodejs, react, serverless etc). It&#x27;s great.

Yes. I use mine for a lot of back-end development (I can run Ubuntu on them and Docker, and have a bunch of containers built for them as well, via a multi-arch pipeline[1] I have been adding to for a while and just cleaned up for re-use).[1]: <a href="https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;azure-pipelines-multiarch-docker" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;azure-pipelines-multiarch-docker</a>

Yes, I use my R.Pi3 as a development server.I run Nginx -&gt; Postgrest -&gt; PostgreSQL on the R.Pi, and it has served me faithfully for more than a year. It is blazing fast ( _for my needs_ ) and I can quickly replicate and setup another R.Pi if needed in a jiffy. I can&#x27;t wait to port my setup to the new ARM64 R.Pi4!

Has anyone had success using an ARM based system for local development in Linux?

I have a 10tb external hooked to my routers usb 2 port and have always been looking for something better. This looks like it.

This script is really nice: <a href="https:&#x2F;&#x2F;github.com&#x2F;Nyr&#x2F;openvpn-install" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Nyr&#x2F;openvpn-install</a>It sets up systemd and iptables and generates all certs and keys and wraps them up into tidy, per-client .ovpn files

Another to check out is <a href="http:&#x2F;&#x2F;www.pivpn.io" rel="nofollow">http:&#x2F;&#x2F;www.pivpn.io</a>. Very easy to setup and use.

Do you have a good guide to setup a nice VPN server?

Not OP but... If I would guess hes using OpenMediaVault? It works rather well on even gen 1 pi&#x27;s.

&gt; I&#x27;ve been using the RPI2 as my HTPC&#x2F;NAS at my folksCould you provide some details? The USB-adapted ethernet &amp; lack of wifi sounds limiting for a NAS.

The HEVC codec may well be an additional cost for CODEC license as is the case with VC-1 and MPEG2(though that expired!).<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;configuration&#x2F;config-txt&#x2F;codeclicence.md" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;configuration&#x2F;conf...</a>So unsure at this stage, but that may well be the case for any license fees regarding HVEC. Heck, if they have absorbed those costs into the base price - I&#x27;d be utterly amazed.

are you speaking about the pi 4 or 2?I just setup my RockPro64 with 4GB, also PCIex4, have an SSD, going to setup a raid at somepoint when I get it all figured out. The board was a bit more expensive than the pi4, but I am interested in playing around with it.But it looks like its back ordered for awhile

&gt; The ethernet controller was an USB one, and was neither really stable or took load very wellHmm... that explains a problem I had with a pi of mine. Every time the 10&#x2F;100 switch it was connected to rebooted, the pi would lose its ethernet link until rebooted. Never had this with other machines on the same switch.

Hmm, I&#x27;ve been using a Pi 3B as a router for ~6 months with no issues like that. I wonder if these were resolved at some point?

&gt; I&#x27;ve been using the RPI2 as my HTPC&#x2F;NASUsing the Pi as a file server can be a bit flaky. The ethernet controller was an USB one, and was neither really stable or took load very well. The new PHY on a dedicated link is probably the single biggest improvement with this new revision.The HEVC is a bit unexpected considering the high license fees and general uncertainties. Let&#x27;s hope the documentation can be released as well.

There is an official PoE board that fits the pi 3+ which uses a 4 pin header by the ethernet jack to grab power. The pi 4 appears to have the same header.<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;poe-hat&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;poe-hat&#x2F;</a>

did they finally release the 100W spec? IEEE really let that spec languish for too long -- vendors got impatient and implemented their own. i had to write 60W PoE code supporting three different specs around 2015. bosch&#x27;s design was the worst.

&gt; now allows for up to 100W per port:It doesn&#x27;t draw anywhere near that. 15W max (for accessories), and 7W in heavy use (without anything other than the board itself).

&gt; Gigabit Ethernet!Does it have PoE? Having to deal with one less cable would be nice.Especially given that the latest spec, IEEE 802.3bt from September 2018, now allows for up to 100W per port:* <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Power_over_Ethernet" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Power_over_Ethernet</a>

I agree with your excitement! I&#x27;ve been waiting for this upgrade forever. I keep looking at the other options out there, but while their hardware is great, their software is terrible.

I&#x27;m intrigued as to why they didn&#x27;t use a big.LITTLE design (or whatever they&#x27;re calling it these days). Perhaps mainstream-linux still isn&#x27;t so great at handling it.

Even so, A72 is a highly-inefficient chip (which is probably why they set such a low clock speed for it). Cortex-A73 would&#x27;ve been much better. But I guess there always has to be at least one obvious lacking in Raspberry Pi generations.

&gt;Video playback at 4K requires H.265Not really a con IMO, I haven&#x27;t seen anything on a 4k bluray encoded in h.264, everything seems to be 265. The microHDMI is kind of a bummer though.I actually wonder if the A72 CPUs onboard are fast enough to do software h.264 4k decode. They might be.

TLDR; of cons from various sources:- New SoC puts out more heat. Active cooling more important now.- Video playback at 4K requires H.265- Micro-HDMI cables now needed.- Draws more power.Other than that, looks like a major performance boost.

Does it really compete with the Jetson Nano? I thought it was designed for AI stuff

Where do you get a jetson nano with free shipping?

When you add up adapters and cables the rpi is closing in on a chromebook on sale. So not that cheap any more.

IMO, at this point you&#x27;re not paying so much for the pi, but rather for the community and accessories. It&#x27;s the entire environment that makes the pi useful; not just the hardware.(I speak as someone who sucks at programming and doesn&#x27;t spend a 1&#x2F;100th of the time learning the latest as I used too as a teen. So having the community around to help with my latest project that I need something more than a microcontroller for, is immensely worthwhile. Obviously those who don&#x27;t need these types of spillovers would probably be better served with other hardware.)

Excited too, but $55 + $13.95 shipping = $68.95 is inching closer to the $99 (free shipping) territory of the Jetson Nano.

Do you have a blog or something for us, mortals, to learn

I&#x27;m wondering if you could power two USB 3.0 2.5&quot; HDD through the Raspberry Pi 4 without requiring external power supplies for them now.Would be nice to build a NAS with as few cables as possible.

An alternative would have been a powered USB hub.

I like the usb-c input.The big shortcoming of the other Raspberry Pis I have is power. Plug anything into it and you risk undervoltage problems (even with the official supply)<pre><code> [ 49.910905] Under-voltage detected! (0x00050000)
 [ 76.949928] Voltage normalised (0x00000000)
 [ 436.806032] rpi_firmware_get_throttled: 1 callbacks suppressed
 [ 436.806038] Voltage normalised (0x00000000)
 [ 438.886093] rpi_firmware_get_throttled: 2 callbacks suppressed
 [ 438.886100] Under-voltage detected! (0x00050000)
 [ 445.126338] Voltage normalised (0x00000000)
 </code></pre>
I hope the new power input will stablize things.

Oh my! This is such a crazy upgrade. I&#x27;ve been using the RPI2 as my HTPC&#x2F;NAS at my folks, and I&#x27;m so happy with it. I was itching to get the last one for myself.USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?!What the!? How the??! I know I&#x27;m not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited!I&#x27;m setting up a VPN to hook this (when I get it) to my VPS and then do a LOT of fun stuff back and forth, remotely, and with the other RPI at my folks.

Oh wow, this will make one of my projects go from four raspberrys to one.

&quot;The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports.&quot;Better than one could&#x27;ve hoped!!

Nope, it&#x27;s completely unfettered by USB this time.

Nope, according to <a href="https:&#x2F;&#x2F;opensource.com&#x2F;article&#x2F;19&#x2F;6&#x2F;raspberry-pi-4" rel="nofollow">https:&#x2F;&#x2F;opensource.com&#x2F;article&#x2F;19&#x2F;6&#x2F;raspberry-pi-4</a>&gt; The BCM2835-based chip in Raspberry Pi 1 to 3 provided just one native USB port and no Ethernet, so a USB hub on the board provided more USB ports and an Ethernet port. The 3B+ added a dedicated LAN chip, which gave it Gigabit Ethernet, but this was limited to USB2 speeds. The Pi 4 has dedicated Gigabit Ethernet, and because it&#x27;s no longer throttled over USB, its networking speeds are much faster.

Oh this is great. WiFi and gbit ethernet onboard is what I needed.Is USB and network bandwidth still shared?

Thanks, didn&#x27;t know about that. Will have to look into it.

Does it matter as much now that one can get Wolfram Engine + Jupyter for free on any machine?

Cool. Mathematica would actually be usable now.

&gt; In the past, we’ve indicated 2020 as a likely introduction date for Raspberry Pi 4. We budgeted time for four silicon revisions of BCM2711 (A0, B0, C0, and C1); in comparison, we ship BCM2835C2 (the fifth revision of that design) on Raspberry Pi 1 and Zero.&gt; Fortunately, 2711B0 has turned out to be production-ready, which has taken roughly 9–12 months out of the schedule.

What a surprise! Didn&#x27;t they say RPi4 is coming next year?

Can&#x27;t speak for OP but I don&#x27;t want my main PC on all the time if I&#x27;m streaming away from home.

&gt; Why not just have a NFS server on your more powerful computer for the Pi to stream the file from?The “more powerful computer” is a laptop, and it is only being used for torrenting the films because it has gigabit ethernet. I don’t want to have to leave it on all the time, and sometimes it is still packed in its case when I want to sit down and watch a film. Storing the films on a hard drive attached to the Pi is a lot more convenient.

Not at all. The reason I upgraded my home LAN many years ago was exactly because 100Mbps is not enough to stream 1080p videos.It does suffice on average, but the bitrate changes a lot within the same file.

I imagine the wait must be agonizing! Why not just have a NFS server on your more powerful computer for the Pi to stream the file from? 100 Mbps is easily enough to stream any Bluray.

The ethernet port on the 3B+ is still attached to the USB hub on the board. In my tests it never gets more than 300 Mbps. The Pi 4 should have true GigE support because it doesn&#x27;t have that limitation.

&gt; The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneckThe model 3B+ already had this though.

at 2-4 Gbps maximum because of shared bandwidth, slower than a single USB 3.0

I had no issues using an RPi 3 for my media center, playing 1080p video from an external hd, but my TV is pretty cheap and barebones.

I&#x27;ve never had these problems with the various media center apps. My Pi 3B+ has been running Kodi for a few months now, and it happily plays 1080p videos at what appears to be smooth 60 FPS.Mind, this is specifically running under Kodi, which is optimized as a media center, and is NOT running also a full desktop environment. Attmepting to do the same in, say, the stripped down Chromium browser was an exercise in frustration. That&#x27;s always been a major limitation of the 3D acceleration in the Pi, as the libraries took a long while to mature and were always a bit hacky.The announcement for proper OpenGL support and compositing in the desktop environment is huge for me. It seems like it&#x27;ll finally push the Pi up into &quot;workshop computer&quot; territory that, while underpowered, should be just capable enough to run some of my always on operations and act as a lightweight CAD station for small parts. I ordered one as soon as I woke up and saw the announcement, and we&#x27;ll see how well that works in practice.

What review did you read? Playing video is likely the only thing the PI 3 does really well; even most H265 FHD do play without stuttering on the 3+ although we&#x27;re close to the board limits.Are you sure the writer didn&#x27;t use the board the wrong way? Some people still believe that videos should be streamed after being transcoded because that is the only way to watch them on their ridiculously limited smart TV which lacks the necessary codecs to watch them the right way. Of course doing this over WiFi would make the problem even worse.
To optimize network usage, videos should be kept encoded until they reach the player so that the network won&#x27;t be clogged. If you use the PI to read the movie as a file over a shared SMB or NFS directory, the network usage is so low that you could watch like 20 different movies on 20 different players on the same home network at the same time. Probably even more.The PI 3 (and to some extent probably the PI4 too) is still behind many other boards in other contexts (openness, performance, price) but playing video is surely not one of them.

<a href="https:&#x2F;&#x2F;knowyourmeme.com&#x2F;memes&#x2F;events&#x2F;the-verges-gaming-pc-build-video" rel="nofollow">https:&#x2F;&#x2F;knowyourmeme.com&#x2F;memes&#x2F;events&#x2F;the-verges-gaming-pc-b...</a>tl;dr they &quot;built a gaming pc&quot; with a &quot;wireless anti static bracelet&quot;, RAM installed in single channel, backwards PSU, terrible parts choices... don&#x27;t trust the verge.

Can you link it? Was the video streaming or playing from disk? Perhaps it was an unsupported video codec? There are certain circumstances where the pi may struggle to play video, but I think for common formats they graphics driver has hardware level support for decoding. If the video format was weird and it had to decode with the CPU it could see problems. Another issue is the power supply. If you do not use a quality 2A power supply, a little red light by the power jack will indicate reduced power and it will throttle the CPU. This applies to the older PIs, but I&#x27;ve not seen the Pi4 yet.

&gt; Raspberry Pi 3 media centerJust read theverge review on how the Pi struggles to play a video full screen, even if resolution is 480p. How are then people using it as a media center?

Are you running it as both NAS storage and a Plex server? How&#x27;s transcode performance?I put together a NAS&#x2F;Plex box with a Kaby Lake Celeron and some hard drives, but I was thinking of splitting it out into separate NFS and Plex servers.

As to properly balance out this review, what exactly were the issues you had that needed to be answered by a community for the RockPro64? The RPi seems to have a slew of things that just work on it out of the box, and if there are issues, 99.9% of the time you can find the solution with a quick Google. Very curious to understand what type of issues something like the RockPro64 (which has appeared numerously in this thread as a &#x27;great alternative&#x27;) faces for anyone interested in the alternatives.

I just put together a Plex server with the RockPro64 4gb ram, PCI3x4 with 2 sata ports. I booted it up with Dietpi and things are running smooth!The board is a bit more expensive, but you can probably get it faster than the pi4 at the moment.The Dietpi community seems to be pretty great, any issues I ran into were answered pretty quickly

&gt; I have had gigabit internet for a few years nowKeep in mind that you are in a very small world there... most people alive today will never have internet that fast, personally i&#x27;ve never had a connection above 6 Mbits in the middle of a city, and I know that&#x27;s likely above the median globally (keep in mind average is a poor metric due to connections like yours, SDL is still the primary type of endpoint for homes)My point being, the previous generations USB based ethernet still has massive headroom for the vast majority of peoples internet.

The addition of gigabit ethernet and USB 3.0 means that a Pi no longer feels like a bottleneck in one’s home network. I know that the Pi was invented as an educational product, but thanks to the Linux distribution OSMC it is commonly used as a media center for playing films, music, TV, etc.I have had gigabit internet for a few years now, and every day on average, I torrent a Blu-Ray image onto my main computer. However, subsequently moving the Blu-Ray to my Raspberry Pi 3 media center is always slow on two counts: 1) ethernet from the router to the Pi was limited to 10&#x2F;100 speeds, and 2) the Pi could push large files to an attached hard drive only over a USB 2.0 port. Consequently, on a Raspberry Pi 1–3 it takes an hour just to move a high-definition file around one’s home network! On a Pi 4, it looks like one can just put the torrent client directly on the media center.

also, 15W is max power I suppose, how low can it go if you configure and use it for small tasks

Yes, there are adaptors, but it won&#x27;t fit with the same loopback HDMI board that&#x27;s included with the screen. It&#x27;ll need a wire, which effectively doubles the space it&#x27;ll take up on a desk.If there are any other high-res small (&lt;= 4&quot;) screens, please let me know - the highest DPI that I know is an iPhone 4S 960x640 3.5&quot; screen with a Creotech adaptor.

Just need a bigger battery. 15W is achievable. You&#x27;ll add more weight obviously but you get the extras of the pi4. Tradeoff.As for the screen you pointed to, isn&#x27;t an adapter available?

How about a RAMDisk?<a href="https:&#x2F;&#x2F;hackaday.com&#x2F;2019&#x2F;04&#x2F;08&#x2F;give-your-raspberry-pi-sd-card-a-break-log-to-ram&#x2F;" rel="nofollow">https:&#x2F;&#x2F;hackaday.com&#x2F;2019&#x2F;04&#x2F;08&#x2F;give-your-raspberry-pi-sd-ca...</a>

You don&#x27;t have to boot off of the SD.

Con for me is still SD storage :-(
At least now an SSD over USB3 should be reasonably fast

My first reaction to the specs:Pros:+ USB 3: Very nice! Finally a pocket-sized, fast USB host.+ Dual HDMI: Could be useful as a projector computer.+ 1.5 GHz: Good, it might be fast enough for some real work.+ Gigabit Ethernet: Excellent for those using it as a NAS.+ USB-C for power: Not surprising, it&#x27;s the standard now.Cons:- MicroHDMI: Incompatible with the 800x480 HDMI 3.5&quot; screen [1]. Also different again to the MiniHDMI on the Pi Zero (will there be a new Pi Zero soon? Who knows.)- Power consumption! They recommend a 15W power supply, which means I&#x27;m pretty sure this won&#x27;t run on batteries.[1] <a href="https:&#x2F;&#x2F;www.aliexpress.com&#x2F;item&#x2F;New-3-5-inch-800x480-IPS-LCD-Touch-Screen-Display-USB-HDMI-Monitor-For-Raspberry-Pi&#x2F;32907399620.html" rel="nofollow">https:&#x2F;&#x2F;www.aliexpress.com&#x2F;item&#x2F;New-3-5-inch-800x480-IPS-LCD...</a>

Yep. Only yesterday I updated the scripts for my Pi 2 cluster (<a href="https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;raspi-cluster" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;rcarmo&#x2F;raspi-cluster</a>), and getting <a href="https:&#x2F;&#x2F;k3s.io" rel="nofollow">https:&#x2F;&#x2F;k3s.io</a> running on a cluster of Pi4s seems like a good way to upgrade that.

I have a ClusterHat on a pi3. I am rather looking forward to using it on a p4 since memory space was primarily the issue I had with the controller. The 4 zeros are fine because I don&#x27;t run a gui on them. The extra speed between the bunch of them will probably go a long way, too.

For those building toy clusters out of Pis for fun and education that 4GB of RAM and gigabit ethernet for $55 is awesome!

They remove all the bottleneck from the previous generations making it more interesting for networking and desktop use.

It&#x27;s a combination of an exciting and hugely popular device gettting a huge upgrade (RAM and networking speed has previously been really limited) and the completely suprise of the announcement: The version 4 was supposed to arrive in 2020, but apparently hardware development went quicker than expected.(How often does this happen?)

I always feel like I&#x27;m missing something. I don&#x27;t have a single idea where something like this could be useful. Maybe because I don&#x27;t care about &quot;fun&quot; projects and live a quit minimalistic live style? I must don&#x27;t have (small) problems with no solutions. Then again, I&#x27;ve also never had an idea for an interesting software side project.

You can buy a pretty powerful full computer (networking, video, RAM, etc) that fits on a tiny card for $35. That makes it possible to build all sorts of fun things on next to zero budget - everything from robots to video game emulation systems and tv streaming boxes.The previous 3 versions were already wildly popular, but there were starting to show their age and to be significantly outperformed by Nvidia&#x27;s Jetson Nano. But the Jetson Nano is significantly more expensive (starting at $99). This fixes several of the performance issues people had and keeps the price at the original $35.

Cost &amp; usability.Raspberry pi significantly lowered the barriers to entry for cost and complexity to own a useful Linux computer. The performance for price is really impressive to the point where it seems like the rpi 4 could be a decent daily driver for most people.

I’m not very familiar with the hardware here but could someone elaborate on why this seems to be such a big deal that there are four versions of the announcement trending on the first page?

Damn I remember back when the TK1 was the new kid on the block. The nano looks awesome, I&#x27;m gonna have to get my hands on one of these!

Every year we upgrade our autonomous sailboat controller to the latest Raspberry Pi. This year we face a situation to choose from Jetson Nano and RPi 4. Even the decision is hard to made, now is an exciting moment for robot makers.

That doesn&#x27;t follow. Firstly, I don&#x27;t think I&#x27;ve seen any other SBC vendor fail to publish full schematics. This is a peculiarity of rpi&#x27;s offering.Secondly, nobody is forcing them to add DRM chips to anything. That&#x27;s not something that can be written off on &quot;a contractual obligation made me do it.&quot; They did it of their own will.

As a previous line manager one said to me “yes, and I want a pony”. That they want to be more open does not mean they are currently fully open – in fact, it requires them to not yet to be fully open. Their primary goal (last I checked) is to be cheap, being fully open is at the very best their secondary goal.

Other SBC makers don&#x27;t have an issue offering full schematics, yet, due to their smaller size, have relatively more to lose from being cloned. Moreover, I hope nobody believes that a lack of full schematics is going to stop people from making clones. Schematics can be reversed with not too much effort. Due to their large audience and brand recognition, rpi actually has less to fear from clones than smaller SBC vendors.If anything, it seems like they&#x27;ve judged that their large size and brand recognition is something that they can coast on to avoid having to offer what other SBC vendors do.I&#x27;m not complaining about rpi existing, I&#x27;m pointing out that what they offer is in certain aspects inferior to the offerings of smaller SBC vendors, which is actually surprising, given that their large size should make them much better resourced to match or exceed the offerings of those vendors. This causes me to question whether these values are actually a priority at all, even if they claim so.

&quot;freeloaders just turn up and demand more.&quot;If this were software, this would be a discussion about open source, would you accuse people of forking an open source project of being freeloaders?

&gt; They do something good but freeloaders just turn up and demand more.I hope you realize that by &quot;they&quot; you mean the hardware vendor and by &quot;freeloaders&quot; you mean the vendor&#x27;s customers.

They&#x27;ve specifically said that the camera module DRM chip is there because they make money from selling the camera modules and they don&#x27;t want third-party cloners undercutting their pricing and eating into their profits, as happened with the non-DRMed version one of the camera module. Thing is, the third-party camera modules aren&#x27;t just much cheaper, they&#x27;re also offered in a whole bunch of useful variants that aren&#x27;t offered officially. So in order to ensure their continued profits, they&#x27;re using DRM to actively make their platform less useful.

Is 1) really valuable? There&#x27;s plenty of computer hardware you could put a fully open software stack on that&#x27;s as or more powerful than an RPi and would otherwise just end up in a landfill or whatever. Open hardware would be significantly more interesting.

1) They make a low cost computer where they&#x27;ve put significant work into making it more open software wise.Their revenue stream is through the sale of their hardware, why do they need to allow people to make clones?2) Maybe it&#x27;s to do with the terms in which they get the camera module?I don&#x27;t know but I don&#x27;t see them selling the camera as interoperable.Your comment just seems to exemplify the phrase:&quot;No good deed goes unpunished&quot;They do something good but freeloaders just turn up and demand more.

It&#x27;s just a standard squatted domain, I don&#x27;t see any spam trap.

&gt; This stated intention and rpi.org&#x27;s actionsPlease, never shorten or distort domain names... I went to rpi.org which turned out to be a spam trap.

Citing the part with the VideoCore is just fully nonsensical. The Raspberry Pi is the only SBC out there with a fully open-source, production-level graphics driver.

I don&#x27;t agree with the parent but it isn&#x27;t an example of whataboutism.
He&#x27;s taking issue with the stated aim of openess, with examples he feels aren&#x27;t open.

&gt; This stated intention and rpi.org&#x27;s actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics?Why do people tend to dismiss the openness of the RasperryPi with completely unrelated things? This is the classic case of Whataboutism[0].Just because you can&#x27;t replicate the entire product in your garage, it doesn&#x27;t mean that it isn&#x27;t quite open already.[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Whataboutism" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Whataboutism</a>

Thanks to you and @kingosticks above for digging up these official accounts.Cursory examination of rpi firmware suggests that this DRM logic is implemented in start.elf, one of the proprietary blobs required to boot an rpi. This is, in itself, significant, since opening this blob would obviously make this restriction easy to circumvent. In other words, rpi have taken design decisions which essentially motivate them not to open up these boot blobs, but rather use them as a chokepoint of control over the platform, see also [1].From this, we can infer that rpi.org will probably never get rid of these boot blobs (as opposed to simply not having found the time&#x2F;resources to do something about them).[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;nucular&#x2F;raspi-keygen" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;nucular&#x2F;raspi-keygen</a>

IIUC, you&#x27;re saying that, for the Raspberry Pi designers, being open hardware is not only not a requirement, but there&#x27;s actually requirements to be aggressively closed hardware in some regards?

&gt; Secondly, why was rpi.org caught adding DRM chips to their optional camera addon board?to stop counterfeit boards. There are many _other_ cameras that you can use for the rpi, so its not like they are trying to block out competition. its to stop people making illegal clones and ripping people off. (cough I&#x27;m looking at you amazon)see semi official explanation here: <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;forums&#x2F;viewtopic.php?t=149426" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;forums&#x2F;viewtopic.php?t=149426</a>The people that make the raspberry pi are a not for profit, they use the money made to sponsor children learning to code. Its not like they hide their aims: <a href="https:&#x2F;&#x2F;static.raspberrypi.org&#x2F;files&#x2F;about&#x2F;RaspberryPiFoundationStrategy2018%E2%80%932020.pdf" rel="nofollow">https:&#x2F;&#x2F;static.raspberrypi.org&#x2F;files&#x2F;about&#x2F;RaspberryPiFounda...</a>tl;dr:its to stop people making knockoffs, taking money from a foundation who are trying to educate an entire generation.

This doesn&#x27;t add up either, since they seem to be effectively walling themselves into not opening up some of the software needed to boot rpis, which remains proprietary. See <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20261549" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20261549</a>

These SBCs are for development. Failing to publish the schematics makes evaluation harder.

My understanding is that they mean open in software not hardware.

Someone has published the HMAC key for the camera DRM module: <a href="https:&#x2F;&#x2F;gist.github.com&#x2F;marcan&#x2F;6dde73a9a0c917cd4fc9784a0a73efe3" rel="nofollow">https:&#x2F;&#x2F;gist.github.com&#x2F;marcan&#x2F;6dde73a9a0c917cd4fc9784a0a73e...</a>

&gt;Are you still using VideoCore?&gt;Yes. VideoCore 3D is the only publicly documented 3D graphics core for ARM‑based SoCs, and we want to make Raspberry Pi more open over time, not less.This stated intention and rpi.org&#x27;s actions are simply not isomorphic. If they want to make Raspberry Pi more open, firstly, why do they publish only abridged (read: fake) schematics? [1]Secondly, why was rpi.org caught adding DRM chips to their optional camera addon board? [2][1] <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;hardware&#x2F;raspberrypi&#x2F;schematics&#x2F;rpi_SCH_4b_4p0_reduced.pdf" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;hardware&#x2F;raspberry...</a> Note the nonsensical, incomplete nature of these schematics, and the complete absence of details such as the USB3 ports, and most of the SoC&#x27;s connections.[2] <a href="https:&#x2F;&#x2F;hackaday.io&#x2F;project&#x2F;19480-raspberry-pi-camera-v21-reversed&#x2F;log&#x2F;53217-pi-camera-driver-makes-deal-with-the-devil" rel="nofollow">https:&#x2F;&#x2F;hackaday.io&#x2F;project&#x2F;19480-raspberry-pi-camera-v21-re...</a>

oh hell YES. this will be my next Media center!!Outstanding. Very pleased with this upgrade

I hit this with the release of the model 3.But it is sort of refreshing not to have the early announcements and then wait for ages for the actual release. And to then either have further delays or find a half finished product that was rushed out to meet some promised deadline. Plus I like waking up to surprise rpi announcements!

I hear you, just bought 4 rpi 3 b+ for a k8s cluster last week and this drops today. Urgh.

Presumably they don&#x27;t want to get Osborned.<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Osborne_effect" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Osborne_effect</a>

It feels like every time I get round to doing a project with a Pi they create a new one with literally no indication or advertising. Suddenly out of the blue a new one appears.

They were already the most used, it&#x27;s gonna be even more so. Impressive

The most important change for me is finally Ethernet is not throttled through usb2

Sure I can just buy an adapter, but then I have to keep track of the adapter and always deal with an adapter hacking of the board making it more awkward to handle.

The cheapest maybe, but don&#x27;t I need to watch for specs and DRM features and everything?

You make it sound like they are being unreasonable, but just like USB-Micro to USB-C and X to headphone jack, it&#x27;s a huge inconvenience when you can&#x27;t find&#x2F;don&#x27;t have it to hand.I used to lose the Micro to C adapters all the time, I lost the C to headphone for my OnePlus6T while travelling and was unable to find a replacement so no headphone use for me.Also, I have about 12 Raspberry Pis, as many display devices, a dozen or so other HDMI devices such as consoles etc, and tens of normal sized HDMI cables lying around and they&#x27;re all compatible.

<a href="https:&#x2F;&#x2F;www.aliexpress.com&#x2F;wholesale?catId=200003201&amp;initiative_id=AS_20190624015006&amp;SearchText=mini+hdmi+to+hdmi" rel="nofollow">https:&#x2F;&#x2F;www.aliexpress.com&#x2F;wholesale?catId=200003201&amp;initiat...</a>

You&#x27;ll need a micro-hdmi cable, not mini.

C&#x27;mon, a mini-hdmi&lt;-&gt;hdmi cable is 50kr ($5), surely you can just buy one and be done with it, no adapter needed.<a href="https:&#x2F;&#x2F;www.netonnet.se&#x2F;art&#x2F;ljud-och-bild&#x2F;kablar&#x2F;hdmi-kablar&#x2F;andersson-hdmi-hdmi-mini-15m-black&#x2F;166806.13707&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.netonnet.se&#x2F;art&#x2F;ljud-och-bild&#x2F;kablar&#x2F;hdmi-kablar...</a>

Apple style - just buy more overpriced adapters.

Exactly, you can solve the dual-display problem via daisy-chaining a couple of DisplayPort monitors instead. Using Micro HDMI was a bad decision in my opinion.

Almost certainly because the SoC they are using has native HDMI onboard, and no native DP

&gt; displayport [...] royalty-free.If I remember correctly (and that&#x27;s a big if), DisplayPort started royalty-free but then they introduced royalties. From my blurry memory: I checked once many years ago and it was free, but then I checked again a couple of years later and it wasn&#x27;t exactly free any more. Did it change again? Or am I completely wrong from the start? If someone remembers the history better than I do...

&gt; more commonMore common in monitors perhaps, but I don&#x27;t think I&#x27;ve ever seen a TV with a DP input. Since AFAIK the target market of the RPi is &quot;plug it into a TV, plug a cheap USB keyboard and USB mouse, and you have a working computer&quot;, having HDMI output is a requirement.

I agree. No idea why they went with micro-hdmi, when mini displayport is more robust, more common, and royalty-free.

No normal sized HDMI sucks, I don&#x27;t want to buy another adapter, aside from that this looks really cool, can&#x27;t wait to get one

Network booting is supported. I don&#x27;t know if the architecture is similar enough to the x86 bios loading network card option roms that one could say the &quot;ethernet controller supports&quot; it. Booting on ARM is different.<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;hardware&#x2F;raspberrypi&#x2F;bootmodes&#x2F;net_tutorial.md" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;hardware&#x2F;raspberry...</a>

yes. rpi3 could do it, 2 with bootloader on sd card.

There are u-boot forks that support RPi ethernet. <a href="https:&#x2F;&#x2F;elinux.org&#x2F;RPi_U-Boot" rel="nofollow">https:&#x2F;&#x2F;elinux.org&#x2F;RPi_U-Boot</a>

This blog post[0], says that it&#x27;s not yet supported by the RPi 4, but that it&#x27;s coming in a future firmware ugprade.[0] <a href="https:&#x2F;&#x2F;blog.mythic-beasts.com&#x2F;2019&#x2F;06&#x2F;22&#x2F;raspberry-pi-on-raspberry-pi&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.mythic-beasts.com&#x2F;2019&#x2F;06&#x2F;22&#x2F;raspberry-pi-on-ra...</a>

Does anybody know if the ethernet controller supports PXE boot?

they are better, modern, more efficient and cheaper CPUs in 2019the fact that they decided to go with a 2015 inefficient one is kinda strange

Minimum 2x performance over previous gen(s) on every test with only ~1W extra power draw. That&#x27;s seriously impressive!

In the video here <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;magpi&#x2F;raspberry-pi-4-specs-benchmarks&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;magpi&#x2F;raspberry-pi-4-specs-bench...</a> they said they doubled the SD card performance.

Found from the new docs:<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;hardware&#x2F;raspberrypi&#x2F;bcm2711&#x2F;rpi_DATA_2711_1p0_preliminary.pdf" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;documentation&#x2F;hardware&#x2F;raspberry...</a>&quot;The Pi4B has a dedicated SD card socket which suports 1.8V, DDR50 mode (at a peak bandwidth of 50 Megabytes &#x2F; sec). In addition, a legacy SDIO interface is available on the GPIO pins.&quot;

Missing: SD card performance benchmark. Previous models could only read about 20 MB&#x2F;s or so, while the modern SD cards can do 10x (maybe even more) that.Is there any improvement in this? It&#x27;s pretty important as RPi usually boots off it.

The full specs and benchmark link: <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;magpi&#x2F;raspberry-pi-4-specs-benchmarks&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;magpi&#x2F;raspberry-pi-4-specs-bench...</a>

That&#x27;s really too bad. It makes the 4K support useless for building an HTPC, which is a common use for the Pi. As far as I can determine, several of their competitors already support 10bit decoding, although specifics (about stable HDR support) are sometimes hard to come by.

The spec table says VideoCore VI. I really hope that is not a typo. I suspect it really is a VC6 because 2x4k is a big bump in pixel count and without a corresponding bump in fill-rate, perceived performance will drop.[edit] looking at the benchmarks it&#x27;s a modest boost. Now about twice the FPS of a PI-2 for Quake3 at equal resolution. Be interesting to see if something with more complex shaders changes the relative performance.

The Raspberry Pi 4 B uses ARM VideoCore IV. As far as I can find HDR will only come in the updoming VideoCore V.
So no. No HDR yet.

Can you stream from a local media source, e.g. SMB share?

Yeah, the Shield seems to be the standard here. If we can get confirmation that the Pi works, we&#x27;ll have an alternative that is much cheaper and is more useful as a general purpose platform!

don&#x27;t want to derail the RPi4 celebration, but for this specific purpose (media centre) I&#x27;ve been super happy with Nvidia Shield. You can often pick them up for $150 on a sale, less on ebay. 4k HDR, runs Android TV (some people have managed to get Ubuntu running on it too), VLC&#x2F;Kodi work well, Moonlight works well for game streaming from another gaming PC with NVidia card. It&#x27;s super zippy, too, and quite small (though bigger than RPi).

I haven&#x27;t been able to get HDR working on my desktop amdgpu + X11. I don&#x27;t think it&#x27;s supported in Wayland yet either (let me know if I&#x27;m wrong) and the devs in #mpv on freenode said they don&#x27;t have HDR10 output support either (although mpv can do HDR10 tone-mapping).For HDR videos, I still play them via my Windows box. I think the current MacOS supports HDR too (and if not, it will get support soon as they have that crazy new $6k HDR screen).

From Libreelec article on RPI4:&quot;The 4B hardware is HDR capable, but software support has a dependency on the new Linux kernel frameworks merged by Intel developers (with help from Team LibreELEC&#x2F;Kodi) in Linux 5.2 and a kernel bump will be needed to use them. Once the initial excitement and activity from the 4B launch calms down, serious work on HDR and transitioning Raspberry Pi over to the new GBM&#x2F;V4L2 video pipeline can start.&quot;Full article: <a href="https:&#x2F;&#x2F;libreelec.tv&#x2F;2019&#x2F;06&#x2F;libreelec-9-2-alpha1-rpi4b&#x2F;" rel="nofollow">https:&#x2F;&#x2F;libreelec.tv&#x2F;2019&#x2F;06&#x2F;libreelec-9-2-alpha1-rpi4b&#x2F;</a>

&gt; 4K!I&#x27;m very excited about these upgrades too (especially GigE), but as far as I can tell nothing on this news page specifies whether the Pi will also support HDR output as part of the 4K upgrade. That&#x27;s most of the practical benefit of 4K - that 4K releases tend to come with HDR10 or DolbyVision support.Anyone know if we can expect HDR output to work? If I knew it supported that I&#x27;d be purchasing one right now to upgrade my media center from my current Pi 3 setup.Even the tech specs page says nothing about 10bit decoding, which is required for most real world 4K HEVC video.&gt; H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;raspberry-pi-4-model-b&#x2F;specifications&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;raspberry-pi-4-model-b&#x2F;...</a>

I&#x27;d love to see other interesting $35 SBCs with reasonable performance.

&gt; There are vastly better SBCs out there.Can you provide some examples please?Always keen to try out any alternatives

&gt; There are vastly better SBCs out there.Which ones would you recommend for this price?

I have a great interest in SBCs mainline compatibility, but I think they will always be &quot;compatible but not fully&quot;, unless a given board will be specifically designed with this objective (at which point, there will be surely a trade off performance&lt;&gt;compatibility).The RPi3 has in fact mainline support, but is not &quot;fully compatible&quot; (at least, in the x86 sense). I guess this will be the case for the RPi 4 also.This is a shame, since any ARM board has essentially an expiry date. For this reason, my next board will be an x86 SBC (the &quot;famous one&quot;), however, it costs considerably more.

Vastly better hardware wise perhaps, but at least you&#x27;ll be able to get a board until 2022.Plus, the Pi 4 will have something approaching mainline kernel support and a large community of people working on it.

As someone who is not familiar with the other options, what would you recommend? I want NAS&#x2F;Video Streaming capability.

Desktop performance my behind. What&#x27;s the point of all that CPU power when IO performance remains in mid 2000s territory? It takes forever to boot, any time disk access occurs everything crawls to a halt. M.2 has been around for 5+ years now and would have easily fit on this design in its short length form factor.No datasheet for the SoC either. Again.There are vastly better SBCs out there.

You can install Android on it, and sideload the Play Store accordingly.Not in a way supported by Google of course.

full specs anywhere?- VideoCore VI graphics, supporting OpenGL ES 3.x - including 3.2? GFLOPS?Does it support Android, Play Store etc?

A53 SoC, new RPi4 with A72 is going to run circles around this one.

Software support is lacking in this device. No OpenGL, no retro gaming with the March 2019 images. Are you configuring yours differently?

The one downside to OrangePi systems is that they use a (semi-) non-standard DC connector (1.8mm I think, definitely not 2.1mm or 2.5mm though).

The OrangePi 3 at $40 is also pretty neat, PCIe 1x, 8GB onboard eMMC, 4x USB 3.0, Bluetooth 5, Wireless AC (pretty sure they beat Raspberry Pi to the punch on this...) and it has mainline kernel support: <a href="http:&#x2F;&#x2F;www.orangepi.org&#x2F;Orange%20Pi%203&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.orangepi.org&#x2F;Orange%20Pi%203&#x2F;</a>

Are you sure? I&#x27;ve worked with a myriad of ARM devices, and I would say that despite their small size, Hardkernel are one of the most responsive companies when I have had issues.I say that as both a Gentoo and Kali ARM dev

They do update their repositories for officially supported SBCs.Of couse, such SBCs have an expiry date (which is also official), but this applies to any vendor, not only to them.Additionally, they&#x27;re one of the most engaging companies when it comes to community - just check their forums and see for yourself.

Not from hardkernel. They have decent support.

&gt; the Odroid HC2 could also - still - be consideredEven don&#x27;t think about it - shitty support from vendor. They don&#x27;t care about updates in general.

For the RPi 4, they moved the ethernet controller onto the SoC, it&#x27;s not connected via USB any more.

The USB-2-Sata interface is indeed USB 3.0. Thanks. USB 2.0 would be too slow to achieve my 100+ MB&#x2F;s.

The USB port on the Odroid HC2 is 2.0, but the SATA interface is connected to a USB3 but, as is the Gigabit Ethernet.Furthermore, SATA and Ethernet are connected to individual USB3 busses, as opposed to earlier RPi designs where everything shared the same USB2 bus.I haven&#x27;t checked the RPi 4 specs yet, but i can imagine it&#x27;s still the same layout, just a faster bus, which can be &quot;just fine&quot; - it should be plenty fast to saturate a Gigabit ethernet as well as the SSD&#x2F;HDD IO required to do that.

It does at least need a heatsink.  Though it will function without it, you may get temperature warnings, and it will run hot enough to significantly reduce component life.  I&#x27;ve also hooked an old PC case fan to the GPIO pins or a USB port, and it runs slower (5V vs the 12 it expects) but does the job fine.

I had an Exynos 5422, and when it came out it was a great card, however, nowadays, it&#x27;s old generation - it consumes more and it&#x27;s less performing than the latest archictures (A7x).&quot;Double the cores&quot; is not a valid consideration - 4+ core configurations typically have 2&#x2F;4 cores (the 5422 has 4) with a high-powered architecture, and the remainder with a low powered one.Compare for example the XU4 with the N2 - the N2 is more powerful, and yet, it has less cores (4 hp. + 2 lp.) and requires no fan.The RPi is an interesting configuration - they have 4 high-powered architecture cores (4x A72) only. It seems it doesn&#x27;t require any fan.Of course if one requires specific chipset&#x2F;components, we&#x27;re talking about specific use cases, which is another story.

The distinction in actual usage between using cloud, server, and homelab to describe their setup seems to be rooted in their purpose.* Home Lab :: Running a partial&#x2F;full enterprise IT stack for fun and education.* Home Server :: Running primarily internal services like file storage, backups, media streaming, home automation, maybe some light networking.* Home Cloud :: Running primarily external services on the public internet to replace 3rd party SaaS services. More often than not this is done with a VPS provider rather than physical hardware in your home.So maybe you find the terminology annoying since everything is cloud these days but it&#x27;s genuinely useful to us folks in the forums. You can also call &quot;home cloud&quot; selfhosting if you find it less jarring.

I think most ISPs don&#x27;t allow servers on residential, so one would be better off using a home cloud. Preferably one with blockchain to disrupt blocking or throttling.

&gt; compact home cloudCan we just start calling them servers again?

I can&#x27;t read that article because Medium has decided that I have to login to do so (and possibly sign up).Needless to say, I won&#x27;t be reading that link.Wordpress.com wouldn&#x27;t have done that with your content. Just saying.

I had ODROID C2, I don&#x27;t know how things are now but I&#x27;ve returned mine as it hanged a lot and had lots of different issues. At same time I had 2x Raspberry Pi and it worked fine. This was couple of years ago.

That and is there really much point in using ZFS if you can&#x27;t give it complete hardware control over the disk controllers?

I&#x27;d love to run something like this, but I recently switched to ZFS which recommends having a lot of RAM (my NAS has 4GB). It&#x27;s what kept me from going the route of the Helios 4.

I have been using Odroid XU4 for home server (home assistant), personal CCTV, controls IR blaster and other sensors for years, still running perfect without rebooting for months. I also have Pi 3 for Pi Hole, but honestly my Odroid XU4 is more stable than Pi 3.

To me, the RPi is the choice only because every other single board I&#x27;ve used had so much less support than RPi does... I have a 3B+ running retropie and it&#x27;s doing okay, but if this one can also do a decent job with h265 under kodi, I&#x27;ll be very happy indeed.Ordered a starter canakit with a couple extras, and looks like I won&#x27;t see it until August. :-( ... I&#x27;ll probably forget I ordered it by the time it comes.

Depending on the purpose, for example if somebody just wants a compact home cloud, the Odroid HC2 could also - still - be considered: <a href="https:&#x2F;&#x2F;www.hardkernel.com&#x2F;shop&#x2F;odroid-hc2-home-cloud-two&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.hardkernel.com&#x2F;shop&#x2F;odroid-hc2-home-cloud-two&#x2F;</a>- Half the RAM but double the cores. I&#x27;m waiting for some benchmarks to see if the RPi4 is faster and by how much.- Also Gigabit Ethernet and it works great. My downloads are always at 108-111MB&#x2F;s for the whole transfer.- Not USB 3.0 but has &quot;oldschool&quot; SATA through an internal USB-2-SATA adapter. It&#x27;s at least more compact, otherwise the RPi4 with an external USB 3.0 drive will probably work even better.- works with a normal 12V power supply, which could be lying around already, from older external drives.Not to disrespect the RPi4, as I&#x27;ll be getting one of them too very soon.

The LibreELEC developer said that the hardware is HDR (10bit) compatible and &quot;only&quot; the software side is missing for now.<a href="https:&#x2F;&#x2F;libreelec.tv&#x2F;2019&#x2F;06&#x2F;libreelec-9-2-alpha1-rpi4b&#x2F;" rel="nofollow">https:&#x2F;&#x2F;libreelec.tv&#x2F;2019&#x2F;06&#x2F;libreelec-9-2-alpha1-rpi4b&#x2F;</a>

I asked about this here: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20261086" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20261086</a>According to the response I&#x27;ve gotten so far, it will not support HDR or 10 bit. :-( However, the vast majority of SDR content is 8 bit. The few exceptions are mostly a few pirate groups who mostly encode anime.Edit: this is apparently now in doubt.

I&#x27;m cannot determine if the HEVC hardware decoding is full 10bit or only 8bit. A lot of SDR content is encoded in 10 bit for the space savings (or so I&#x27;ve read).

Look at pca9685-based i2c pwm driver boards, it gives you 16 channels and is much more stable and easier to control from userland code than RPi gpios.

Driving an arduino from a pi is still the way to go, which is a shame. I’d have liked to have seen more PWM too.

I wish there were some improvements in the I&#x2F;O aspect of the board. Having tried to use an RPi for a small automation project, I felt limited by the single ADC input and single PWM output. I was faced with using an Arduino daughter board to do the actual IO or going with a BeagleBoard.

not these USB 3.0 ports. Connected with shared 4 Gbps, they only run at 4&#x2F;5th, 1&#x2F;2 or less of the full 5 Gbps speed.

With 4GB of RAM, you&#x27;d even be able to use ZFS.Does it use ECC memory? If not, you should not use ZFS. Without ECC memory, ZFS carries the nasty risk of writing good data with a bad checksum, leading to data loss which would not occur in other filesystems (those that do not try to correct errors on the fly like ZFS).

I tried ZFS with 4 GiB RAM in the past and it was not fun.
Does it work for you?

The USB 3.0 ports should give 100MB&#x2F;s (Benchmarks show up to +300MB&#x2F;s), and you can mirror two disks for RAID-1.With 4GB of RAM, you&#x27;d even be able to use ZFS.

I&#x27;m using an old SATA SSD with a USB3 adapter I got off ebay. Performance is significantly better than an SD card.

The Raspberry Pi 4 has the Ethernet controller on the SoC unlike previous versions, so it does not share the 4Gbit PCIe bus with the USB ports.

Only maximum 4 Gbps shared by 1G ethernet, PCIe 2 and 2x USB 3.0? Thats even less speed than 2 harddisks.

RPI would be awesome for NAS if you could connect SATA somehow

&gt; Does the 4 have a composite outputFrom what I can see on the specs, yes it does.

Does the 4 have a composite output, or is there a hat for it? My game room has a CRT and while I&#x27;d love to stick to original hardware, the price of getting it to read games from non-original media (which is getting harder and harder to come by) is pretty high. An RPi 4 could be  reasonable alternative.

I&#x27;m a complete noob when it comes to RPI, but does it emulate these games well despite not having a strong (or any?) GPU?

The RPI4 w&#x2F; 4GB RAM is going to be a very welcomed upgrade in the emulation scene. N64, PS1, Dreamcast and PSP games will run so much smoother.

Anyone got some clues if this might be worth upgrading for a pure MAME gaming Pi?

FINALLY. The 4Gb of RAM will be useful for a lot of stuff for those who normally used ARM VPSes.

Yeah, for the first time it&#x27;s true gigabit. Results from iperf:Raspberry Pi 3B: 94Mb&#x2F;s

It shouldn&#x27;t be a problem even with older Pis. Pi-Hole only answers DNS requests, which are comparatively tiny. The actual web traffic goes through your regular layer-3 network.

Someone in the comments of that post recommends this automatically updated blocklist <a href="https:&#x2F;&#x2F;github.com&#x2F;notracking&#x2F;hosts-blocklists" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;notracking&#x2F;hosts-blocklists</a>

Pi-Hole is a wrapper around dnsmasq, so you could just run that on your base OS with the same configuration files. Add gravity.sh if you want automated blocklist updating:<a href="https:&#x2F;&#x2F;lowendbox.com&#x2F;blog&#x2F;host-your-own-dns-now-with-100-more-ad-block&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lowendbox.com&#x2F;blog&#x2F;host-your-own-dns-now-with-100-mo...</a>If you already have an available server there&#x27;s no need to spin up a VM to host another OS instance just to run native software...

Gigabit Ethernet?  I&#x27;m tempted to grab a few and try running Pi-Hole for my whole organization (~1200 users) and see how that goes.  :)  I know you can set up Pi-Hole on Ubuntu VMs.  But there&#x27;s something so attractive to me about running it separate from your hypervisors and closer to the core switch on very very cheap hardware....  Been curious about Pi-Hole on my bigger work scale for a while, this may very well tip me to trying it out.
