stas2k··on ZX Spectrum graphics magic
I still remember getting a USSR clone(Leningrad) at 5 years old. It is probably earliest memory I have.

Did not know English, could not read anything, but still spent hundreds of hours first playing, and then tinkering with it.

There was no OS to mess up, and it booted instantly to a Sinclair BASIC prompt.

stas2k··on We asked camera companies why their RAW formats are all different and confusing
Only Nikons I own are 35mm film FM2 and F4. The bodies feel like tactile bliss. FM2 has a dry lubricated system with crazy titanium honeycombed etched shutter and F4 is the last pro DSLR they made with no menu system.

On the digital front I found Fuji X-Txx series to be like tiny Nikons in their usability with all common controls on dials.

stas2k··on OpenWrt 24.10.0 – First Stable Release
Why not both? I also use NixOS as the main router/fw/nat, and OpenWRT in bridge mode as dumb APs.

All updates except semi-recent DSA changes were seamless.

stas2k··on Taildrop lets you send files between your personal devices on Tailscale network
I don't want to sound negative, but I genuinely don't get the premise of Tailscale.

VPN as a service sounds wrong from security perspective, as you are giving away all the keys. The same goes to the VPN providers for Internet access, but that at least is not trusted as much as Tailscale is.

These internal services that are annohnced are just... Services you can run on the Internet with TLS.

stas2k··on YouTube's crackdown on ad blockers intensifies
I had to resort to my own Invidious instance plus Sponsorblock.

Its looks is very much like OG Youtube and it is unusually fast: no overdone JS. You can also sync it up to Clipious on the phone and get a clean, bloat free Youtube experience without ads or slow page loads.

stas2k··on Verilog Ethernet: Work-in-Progress 100BASE-TX PHY
20 Euro Colorlight 5A FPGA boards from Aliexpress come with dual Gigabit Ethernet ports, open toolchain to build a SoC that can access them as well.

LiteX allows me to use it as a Gigabit Ethernet powered logic analyzer with a lot of inputs.

stas2k··on Lego Is Discontinuing Mindstorms
Currently 3D printinga lot of Lego rail on my FDM printer. Although not perfect, it does snap onto original rail and to its 3D printed peers. Lego pieces do snap to the dimples as well, although too tight.

Main use case for me is to lay some track between rooms for kid's trains.

stas2k··on Silly Camera Numbers
Oh yes, I dabbled a bit into using motion picture film stock for photography. It is fun to shoot it by the frame and not in feet, if you have a lab close to you to deal with the process.

Vision3 50D was recently(for film) introduced in 2011, and I had amazing results with it. Super smooth with very good latitude.

stas2k··on Silly Camera Numbers
What tripped me when shooting and developing film is that it usually works in negative. With digital you are always looking for overexposure, while negative film is OK with overexposure. Light builds silver density, while lack of it leaves a clear base with no information.

Then you get an analogue NOT operation when printing the negative on the enlarger. Two negative processes make a positive.

Film photography is very interesting as it combines art with optics and chemistry. Just pure magic seeing the image fade into the paper when developing.

stas2k··on Electrical engineers on the brink of extinction threaten entire tech ecosystems
Could not agree more. I have designed my first PCB in Kicad as a MIT licence project.

Kicad ecosystem is very much alive and I was able to reuse dimensions from another project for the same computer.

I made a RAM expansion board for Sharp X68000. You can check it out on https://github.com/stas2k/galspanic

stas2k··on Hurricane Electric Emergency DNS Maintenance
Same here! Very happy with their free service, and they do support 2FA.

UI is minimal and gets everything done

stas2k··on Kitty: The fast, feature-rich, GPU based terminal emulator
It is also old-school in a way of supporting Xresources based config, while at the same time being super strict on UTF-8 support.

Supports strange edge cases that I saw break other emulators like urxvt.

stas2k··on Osmocom icE1usb: Open hardware USB E1/T1 adapter
I saw them do A5/1 live cracking on stage in Netherlands. It is amazing what you can do with sheer determination. Learned a lot from their talks on GSM.

USB E1 is holy grail when it comes to E1 interfaces. Before that meant a PCI card, which excluded all laptops and SBCs. And it usually required some pretty specific kernels and modules to be installed.

stas2k··on Stanisław Lem's Reflections on the Objects of His Childhood Home
He also has an amazing essay on futurology called Summa Technologiae. It clearly shows his insight into what is happening to our society as we advance in tech.

It was recently translated to English and is a must read.

stas2k··on PS5 Teardown [video]
PS2 was soft-locked to Sony supplied drives.

Nowadays that bay is very useful for booting games off any HDD. SATA is also supported by using a IDE->SATA board.

stas2k··on Writing an x86 bootloader in Rust that can launch vmlinux
Github repo has the same text in the README: https://github.com/o8vm/krabs
stas2k··on Z80 Explorer – a Zilog Z80 netlist-level simulator
Thanks to the author for this OCD-level work. I always find it interesting that netlists out of die images are precise enough to run hardcore test routines.

Z80 has a special place in my heart because of Speccy.

stas2k··on Eastern European Movies
I always use cak(the bell that a certain class has to wear on their nose) as a metaphor for current mask usage. :D Source: https://i.ytimg.com/vi/oCmUxI1UdME/maxresdefault.jpg
stas2k··on RaSCSI: SCSI Interface for Raspberry Pi (2019)
Just wanted to chime in as a happy RaSCSI user. I am using it on my Sharp X68000 with a hat that I built from a PCB + a bunch of buffer ICs.

It offers SCSI disks, CD, Ethernet(tap device on rpi side) and a way to share a Linux directory with the X68k.

Performance is well over what an early nineties computer could require.

First thing I fired up was MMDSP and listened to some awesome tunes available.

stas2k··on Google Kubernetes Engine is introducing a cluster management fee on June 6
Don't want to sound snarky, but how about an upgrade path from 3.11 to 4.x? I am a heavy Openshift user and it seems that RH just dumped whatever architecture they had with pre-4 clusters and switched to a Tectonic-like 4.x installations without any way to upgrade other than a new installation. This makes it hard to migrate with physical nodes.
stas2k··on OpenWRT remote code execution via MITM due to bug in package manager
I have three of them serving 802.11n on 2.4 and 802.11ac on 5 gigs and all work fine.

Know some people who use them for a bridged setup over ac standard. No issues there as well.

stas2k··on OpenWRT remote code execution via MITM due to bug in package manager
Get a Xiaomi Router 3G. It is more difficult to do an initial flash, but is well worth it with an awesome $40 price tag on Aliexpress. Only downside is that it only has 3 GigE ports.
stas2k··on Mail in a Box
You do not need 100% uptime to receive mail. Because email is store and forward, other server will retry for a reasonable time.

The most complex part is setting up all the DKIM and friends to make your outgoing mail authenticated.

stas2k··on Apple of 2019 is the Linux of 2000
Creative was notorious for having chipset-specific PCI bus master issues even on Windows. The only way to fix it was to disable bus master, and that is what Creative drivers did on Windows.

On Linux you were expected to be a grown boy and do it yourself in the BIOS.

stas2k··on The Å-Machine
I like he casually has a Symbolics keyboard on his desk(easily mistaken as Commadore hardware)
