Depends. When working for a company - what they give me. Unfortunately, they usually insist on Macs.

As for my private projects, Xiaomi Mi Notebook Air, 8GB, running Arch Linux is generally more than enough.

My details:

• MacBook Pro (15-inch 2019)
• Processor: 2.3 GHz 8-Core Intel Core i9
• Memory: 32 GB 2400 MHz DDR4
• Graphics: Intel UHD Graphics 630 1536 MB

This is basically among the more powerful Mac laptops before M1. I'm overall satisfied with it. There's more than enough beef here for everything I do. I got it refurbished so didn't pay absolute top dollar.

I'd be happy to lose the touch bar and definitely feel like M1 Chip was a step up I missed out on — though have enough power in this machine to not worry about it, realistically.

At this point I worry that I'm an old dog that can't be taught new tricks enough to really want to leave the Apple ecosystem at this point. Just the way it is despite the premium pricing and certain missed options.

Hmm,

P.S. I'm just a student, I don't develop much software, I mostly run just python.

Windows (laptop!)

• I7 OC TO 4.5ghz
• 32 GB RAM
• M.2 1TB (3700mb/s read write)
• 2 SSDs @2TB each (RAID 0)
• GTX1080 (stripped down PC version, not maxQ)

Was a custom build from PC Specialist.

The only thing I was never happy with was that I couldn’t overclock the CPU and GPU at the same time as it is only a 300 watt power supply and so there isn’t enough power. To be fair it is a laptop so cooling is always fun when stressing it on both CPU and GPU (rendering videos etc) for an extended period.

So I just O/C the CPU and undervolted it slightly to minimise the max power draw and left the GPU stock speeds. Real shame as I won the silicon lottery on both!

The thing still munches through nearly anything and is 5 years old, but I have been eyeing up building a desktop instead as I want to get back into making videos and so a 1080 is now a little slow.

The m.2 was the biggest win, always invest in a fast HDD for Dev work, saves so much time!

I'm a little less concerned about the "computer" per se than the workstation and the OS. So tackling those first and then the computer:

Workstation

My main gig is a standing work desk with a tall saddle chair, a 43" 4K monitor and video and USB cables that plug into the wall, where they are connected a computer beneath the floor in the basement, where I hear no fan noise, and it's consistently cool, and it lives with a a few servers, switches, consoles and such as well. So all I have at my standing workstation is a 43" monitor keyboard and mouse and my desk clutter.

OS and Dev tools

I use Linux Mint. Moved to that some years ago in the Windows 7 days and never looked back. I use a Windows VM very very rarely so rarely I can't remember how to do it when i need to and have notes, ha, ha. Nor do ever envisage looking back ...

And for development, I use mostly Eclipse for my work in Python, JavaScript, bash , PHP - being the primary languages I use I guess. I use the Atom Editor a lot, Joplin for keeping a journal and notes. Git for source control and Github as a remote.

Computer

Os: Xubuntu 20.04 LTS

I will upgrade to a larger SSD but I will keep Xubuntu since it's lightweight and xfce is such a clean, yet customizable desktop and Ubuntu is just great in terms of compatibility

This Laptop is perfect for me !

One that has 0% of its root partition space left!

At home I use a 10 year old Gateway FX6860 desktop running ubuntu and awesomewm. This year she got brand new 16GB of DDR3 and a 500GB ssd and she is running great again. It runs all my web dev and example data pipelines like a champ, with zero issues. Runs Minecraft super well to play with the kids.

At work I have a failrly rediculous laptop. I do far more multitasking on it, so it does get used to its potential, but the difference to the 10yr old deskop is not off the chart. The one thing I really notice a serious bump in is video processing, obs/kdenlive.

Here she is on her 10 year birthday, getting ready for a solid cleanup.

System 76 Lemur Pro, Ubuntu

I love it. I may try to go even further into foss and sustainability, and find laptops with trisquel preinstalled, with stronger pledges similar to fairphone's sourcing pledges.
