Can you not trivially update all these things though? Like how big of a deal is it really? Or are you stuck using their specific distribution, and their distribution can't be updated to a more recent Ubuntu and python?

You can update things but in my experience it wasn't trivial

Is it just the normal process for updating Ubuntu to the next release though? I wouldn't call that trivial either, but only because it'll likely take hours here. Still, it's a well-trammelled path that typically works well and while unattended. So if that's all it is it doesn't seem like a huge deal.

Same as it's always been: Gaming. I bet even this $59 computer can play games surprisingly well. Obviously not modern AAA titles or anything like that, but there's many decades' worth of games it can play (including ones originally released for non-PC platforms). There's lot of interesting Pi-powered handhelds and mini-arcade setups running emulated games; this seems like it'd be significantly better at that.

Gaming is not the purpose of GPU accelerated single board computers. Though you could reasonably play some games on the Jetson Nano, Nvidia markets the jetson series as embeddable machine learning systems. While there may be complaints of how hot the jetson gets or its performance with Ubuntu, the jetson is not intended to be used as a personal computer. It’s cheaper than dirt machine learning access. I highly recomm…

I said it was a use case, not the purpose. But realistically these single board computers are more suitable for gaming than for machine learning. If you don't have a computer at all then I guess you could use a Jetson for this purpose, but a real computer would be much better and is easily within the budgets of most companies and most software engineers.

Is this a developing markets play? I've never heard of someone whose only computer is a Pi/Jetson. By the time you add all the necessary peripherals to use it as your only computer, it costs more than a cheap laptop.

So the point of a Jetson is .. you only have a cheap laptop with terrible integrated graphics, and for $60 you get a much better GPU with this Jetson, and you remote into it?

I think it'll do better in gaming.

I tried to find any documentation, schematics, code and I can't see it anywhere on that website.

You didn't even try. https://developer.nvidia.com/embedded/downloads

Man I swear I got retconned, I just couldn't see this. I would like to retract all I wrote. It's pretty cool!

A five year old ARM chip, the X1[1] is now far & away the best graphics one can get on an $100 single-board-computer.

Double amusing, there is now an ARM core called the X1, a heavyweight follow up to the A76 for bigger form factors.

I think the whole idea for the Nano was having a GPU on a small computer. The RPi doesn't have that. If you're comparing them as plain CPU-based development systems, you're missing the whole point of the Nano.

Just so there is no confusion, the Raspberry Pi 4 supports dual 4k displays out of the box. It has a built in Broadcom VideoCore VI @ 500 Mhz GPU and dual micro HDMI ports so you are good to go. Perhaps you meant a discrete GPU?

This is not about the display. It's about running CUDA-accelerated machine learning stuff. Think - pytorch. That's the whole point of the Nano.

If you're not doing that, use an RPi.

I want to setup something like this for my daughter's primary grade school meetings using Zoom. Any suggestions? Are the Pis or this device up to par now for such use case? I totally do not like Chromebooks, and standard laptops are an overkill.

afaik there's no native Zoom client for ARM [0]. You'll be stuck with the web version of it, which according to some functions poorly no matter where you run it

I have a Jetson nano. It's a nice thing for what it is, and the price. But, the software misses the mark by a lot. It's still based on Ubuntu 18.04. Want python later than 3.6? Not in the box. A lot of python modules need compiling, and the cpu is what you'd expect. Good for what it is, bad for compiling large numbers or packages. They run a fancy modern desktop based on the Ubuntu one. Sure, it's Nvidia, gotta be fl…

this is godforsaken mother-of-all-anti-pattern sinful words. how terrible! don't trust the distro, don't trust upstream! trust only the particular bizarre awkward vendor tool chain? gods no. heavens no. the only reason, the only places this advice is ok is when your hardware is unsupportable, un-un-streamable, when the hardware embodies an anti-supportable form of existence. @jcelerier's advice here could not be more antithetical to the real story. if you need custom weirdo toolchains, something has gone direly wrong.

The more I use linux (12 years), the more I believe that common users should not use "stable distribution". Upgrade is risky, software is always outdated.

this feels like mass cowardice to me. run Debian testing or unstable. run something semi modern. not old lame vendor LTS.

those who cower in LTS land, thinking they are saving themselves from troubles have very very very little experience, scant little too contribute to the community that cares & tries to remain mildly up to date. there is such a prevalent fear based mentality about running decent reasonable modern upstream software but it is such FUD, such a cannot do attitude. rarely can these camps justify their afraid behavior. LTS is nonsense. testing, unstable, they work well, & they expose real honest levels of support for systems, versus relying on antiquated but known support that LTS brings the tepid adopters.

I'm really glad there are still companies with such values. For some strange reason, these days people equate innovation with using fancy/barely tested tools.

It is in the name, marketing, people use Debian Stable, Ubuntu Long Term Support, they don't use Ubuntu Outdated. But that's what it is. The moment it moves to Stable it does not receive versions update. We can't force rename. Maybe we can come up with better names for "testing", "unstable"?

* Fresh

* Upstream

* Rolling

I understand people don't want to switch distribution, channels out of fear, inconvenience. Can cross-platform package manager help? The one with dependency resolution — Nix, not the one that bundles it all together like Flatpak or Snap.
