When I worked at a FAANG, most developers could get remote virtual machine for their development needs. They could pick the machine type and size. It was one of the first thing you'd learn how to do in your emb^H^H^H onboarding :) So it wasn't uncommon to see people with a measly old 13" macbook pro doing the hard work on a 64cpu/256GB remote machine. Laptops were essentially machines used for reading/writing emails,…

Ah so the coding was done locally but run remotely? I nearly went insane when I was forced to code using Citrix.

It sounds more like doing embedded development with a TFTP boot to an NFS mounted root filesystem.

I dunno, alt+tab works as fast for me as moving my head to look at another monitor. And I'm not particularly concerned with "abusing" my laptop. I paid for its chips and all of its cores, I'm not going to not use them...

it is not about the chips or cores. it is about the pcie ssd that you torture it with high temperature for a long period of time due to a laptop poor cooling. or the battery, it does not like high temperature either. you only regret it when it happens. and it will happen.

> and it will happen.

I dunno... I've been doing this a long time. And haven't had any of the failures you're talking about. You're aware these machines throttle performance as necessary to prevent from getting too hot?

OK, I'm convinced. Can someone tell me what to buy, specifically? Needs to run Ubuntu, support 2 x 4K monitors (3 would be nice), have at least 64GB RAM and fit on my desk. Don't particularly care how good the GPU is / is not. Here's my starting point: gmktec.com/products/amd-ryzen™-ai-max-395-evo-x2-ai-mini-pc. Anything better?

Beelink GTR9 Pro. It has dual 10G Ethernet interfaces. And get the 128GB RAM version, the RAM is not upgradeable. It isn't quite shipping yet, though. The absolute best would be a 9005 series Threadripper, but you will easily be pushing $10K+. The mainstream champ is the 9950X but despite being technically a mobile SOC the 395 gets you 90% of the real world performance of a 9950X in a much smaller and power efficient…

And this would be something cheaper https://www.bee-link.com/products/beelink-ser9-ai-9-hx-370?v...

Similar single core performance, less cores, less GPU. Depends what you’re doing.

> Ah so the coding was done locally but run remotely?

Both, depending on the case and how much you were inclined to fiddle with your setup. And on what kind of software you were writing (most software had a lot of linux-specific code, so running that on a macbook was not really an option).

A lot of colleagues were using either IntelliJ or VScode with proprietary extensions.

A lot of my work revolved around writing scripts and automating stuff, so IntelliJ was an absolutely overkill for me, not to mention that the custom proprietary extensions created more issues than they solved ("I just need to change five lines in a script for christ's sake, i don't need 20GB of stuff to do that")... So ended up investing some time in improving my GNU Emacs skills and reading the GNU Screen documentation, and did all of my work in Emacs running in screen for a few years.

It was very cool to almost never have to actually "stop working". Even if you had to reboot your laptop, your work session was still there uninterrupted. Most updates were applied automatically without needing a full system reboot. And I could still add my systemd units to the OS to start the things i needed.

Also, building onto that, I later integrated stuff like treemacs and eglot mode (along with the language servers for specific languages) and frankly I did not miss much from the usual IDEs.

> I nearly went insane when I was forced to code using Citrix.

Yeah I can see that.

In my case I was doing most of my work in a screen session, so I was using the shell for "actual work" (engineering) and the work macbook for everything else (email, meetings, we browsing etc).

I think that the ergonomics of gnu emacs are largely unchanged if you're using a gui program locally, remotely or a shell session (again, locally or remotely), so for me the user experience was largely unchanged.

Had i had to do my coding in some gui IDE on a remote desktop session I would probably have gone insane as well.

This is a little confusing because you were referring to a Core i5-6600 and presumably an i5-7500T or i7-7700T above but now you mention a 5600. Are you referring to a Ryzen 5 5600?

Yes

As we discussed elsewhere you could put the Ryzen 5 5600 into 45W ECO mode and cool it passively. Or a Ryzen 5 7600 if you decide to jump up to AM5 (which is probably a good idea even though you'll need new RAM).

My issue with corporate laptops isn't so much the PC's hardware but the antimalware. I'm not even sure what the antimalware does, and I think, at one time or another, I've probably had all the major ones installed, and they've all managed to slow down my PC down to frustratingly slow speeds.

Really depends on your use case. I personally still run my 17 year old 2.4GHz Core 2 duo with 4GB of RAM as my daily runner. I simply do not hit the walls even on that thing. Most folks here simply would not accept that and not because they are spoilt but their works loads demand more.

a 17 year old core 2 duo machine is definitely less powerful than a raspberry pi 5 that is going to use 1/7th of the power.

Raspberry 5 is a dud, either go 4 or 3588 CM:

Or in a uConsole.

Also Risc-V tablet:

Not as battle hardened as my Thinkpad X61s but maybe we'll get a GPU driver soon... 3 years later...

I worked on a Spring Boot application that would take more than a minute to start. Not Spring's fault, IIUC, but nevertheless a focus killer.

A minute? What was taking so long? Spring itself is only a few seconds (as you said that’s not the issue). That sounds horrible to work on.

If you have many beans that does IO, startup will be slower. For example, just removing sql/database initialization can shave off a second.

If you don't care about power efficiency, sure ;)

I bought a geforce RTX 3080 at launch and boy was I surprised at the power draw and heat/noise it pumps out. I wonder why anybody bothers with the 90 series at all. I actually run it ~10% underclocked, barely affects performance, but greatly reduces heat/noise. These cards are configured to deliver maximum performance at any cost (besides system instability). My next GPU I am probably going mid-range to be honest, th…

More VRAM, and NVLink (on some models). You can easily run them at lower power limits. I've run CUDA workloads with my dual 3090s set as low as 170W to hit that sweet spot on the efficiency curve. You can actually go all the way down to 100W!
