wdfx··on Hacking the T2S+ Out of Fear: Get Lock-In Thermography for Free
Try this perhaps: https://github.com/Swordfish90/cool-retro-term
wdfx··on Ask HN: There is an open-source alternative to almost any SaaS, what do you use?
I'm the only user really, but yes, some services are available on a public DNS. Most of them are only on the local network though. Never had any issues with inbound traffic on my residential connection.
wdfx··on Ask HN: There is an open-source alternative to almost any SaaS, what do you use?
I host on an old i5 dell optiplex and usb raid enclosure i keep in the cupboard under the stairs. It's mostly for making the storage available to my other devices. It's also a tailscale node.

> Mint -> Maybe

I don't know what these are, but how am I supposed to google these words and get the correct results?

I currently self-host these infra and apps:

  - technitium DNS
  - Traefik
  - Cerbot
  - Home assistant
  - samba file shares
  - Gerbera media server
  - Jellyfin
  - Gitlab
  - Grafana / influxdb (for telegraf server monitoring + esphome  sensors)
  - Photoprism
  - Syncthing
  - Taiga
  - Vaultwarden
  - offlineimap sync from gmail
I've been thinking about Nextcloud as well, but it seems a bit heavy-handed and wants control over my docker daemon, which I am not sure about.

wdfx··on Why Gauss wanted a heptadecagon on his tombstone
There's also game versions https://www.euclidea.xyz/
wdfx··on Nanolog supports logging with 7 ns median latency
I think the idea here is to separate the log call site in application code from the log processing/persistence?

So, the nanosecond values quoted are the impact exposed to your application code, but some other process takes over the bulk of the work of the logging.

So as long as the offloaded process can keep up with the average log rate, it'll be fine - but also as a bonus the application does not see increased latency due to logging.

wdfx··on ScreenPlay Is an Open Source Live-Wallpaper App for Windows and OS X
Is there anything like this that works on Linux (x11) ?
wdfx··on Tell HN: Steinberg shut down their eLicenser service, breaking older software
I don't think this is any surprise for anyone using Steinberg software? I no longer use any eLicenser controlled apps, but I have had emails and notifications from Steinberg about this already going back at least a year I think?
wdfx··on Who Wrote the Blue Screens of Death
Has anyone ever successfully used the BSOD register, memory, stack, status dump information to diagnose and fix a fault?

Are those values even useful given that the machine is halted and there's no way to inspect or read any additional information about what was running and where it was in memory?

I suspect there are a select few that can do this, but for the rest of us it's a reboot and reload situation. Also, those that could use this information probably also could fix and resolve the crash without it?

So, what's the point of even dumping that info to screen, instead of putting up a simple "oops, I died, time to restart" message?

wdfx··on Wide angle lens distortion correction from lines
Mine's from 1974 according to a serial number lookup, so who knows what it's been through in the last 50 years.
wdfx··on Wide angle lens distortion correction from lines
I have an old Nikon 500/8 ; gotta be honest, it's not very good.
wdfx··on Back to the future: Are hackers the future of amateur radio?
I've played with a cheap Chinese clone sdr receiver and LNA and filter and have received FT8 calls from Indonesia and Australia on a length of scrap wire I hung up in my loft here in London UK. Calls from all over Europe and from USA are pretty trivial to pick up.

I would be interested in getting licensed to TX, but then to apply that practically I'd need to invest also in 100s - 1000s of £££ of gear rather than a mere 10s. And then once I've done that ... I think the novelty would be mostly gone if I'm honest. I don't think the practical expense seems worth it.

wdfx··on Gitlab Explores Sale
If this news elicits such a strong reaction as this, it makes me wonder why you are even using Gitlab right now, if there is even any likelyhood of such an outcome?
wdfx··on Analog GPS: Scrolling Wrist and Car-Mounted Maps of the 20s and 30s (2016)
I don't think it's upside down, but looks like on the "wrong" arm, though that's debatable depending on handedness. The more I think about this though, this seems like only one of several fundamental issues with this thing :P
wdfx··on Analog GPS: Scrolling Wrist and Car-Mounted Maps of the 20s and 30s (2016)
Love that the photo of the wrist mounted one shows an immediate usability issue; the scroll knobs are on the wrong side?
wdfx··on Show HN: ESP32S3 ZXSpectrum
If you want to do a 128 model version and have it interface to a real AY sound chip, I've written ESP32 code for that: https://bitbucket.org/doughammond/fourays/src/master/
wdfx··on Show HN: SHAllenge – Compete to get the lowest hash
I've parked CUDA for now, I don't understand it enough to care to fix the tooling.

Got an optimised C++ version with no deps averaging about ~24 MH/s on an i7-11800H.

I've got 9 zeros; if I get a result that ranks top 10 I think I'll submit and call it a day.

wdfx··on Show HN: SHAllenge – Compete to get the lowest hash
I've also been spending today building a miner. Started in JS, then JS with worker threads (~2.2MH/s), then c++ with openssl (~3.7MH/s) and now attempting CUDA.

Also have been using ChatGPT to do the code translations.

I'm currently stuck in yak shaving, I cannot compile CUDA programs here yet as on fedora 40 I need an earlier gcc (13.2) which I am now also having to compile from source.

wdfx··on Flameshot – Open-source screenshot software
The annotate/draw in-place in flameshot just made me convert from spectacle.

Also on i3 spectacle is sometimes buggy, it misfires or loses the capture.

wdfx··on PiDP-10 – a modern replica of the PDP-10
I have a couple of J11 chips and wondering what to do with them. Are they just display pieces now, or can they actually be hooked up to modern MCUs and do some "useful" computing?
wdfx··on What is the "God Mode" folder in Windows 10, and how do I enable it? (2022)
Allegedly also works in Windows 11

wdfx··on Why camera calibration is so important in computer vision
Weird that the mars rover has a coin embedded as a scale reference instead of a printed ruler scale?
wdfx··on Ask HN: How do I balance all my 200 interests in life?
I've recently realised (at mid-age, of course) that a lot of my interests are in fact marathons, not sprints. This has actually abated a lot of anxiety around either spreading my attention too thin and feelings about not finishing anything.

To that end, I now feel that it's OK to de-prioritise some interests sometimes, or to just dip in for a short while. And in other interests I spend some time mentally planning and then going step by step and chipping away at progress.

Life is long, take your time.

wdfx··on CADmium: A local-first CAD program built for the browser
Sure, but my primary objective is not "to learn CAD systems" - I just want to get models done for making things.
wdfx··on CADmium: A local-first CAD program built for the browser
On the flip side I spent probably 30 minutes each to get acquainted with Fusion and Onshape, and completed my first designs within a couple of hours.

I've invested several hours already in trying to learn FreeCAD and achieved nothing. Its a hot mess that desperately needs a new UI.

wdfx··on ESP32 Drum Synth Machine
That's good advice; I had thought of doing this, and it requires a little bit of project refactoring, but you are correct that I do seem to already have the tools. Adding a few more unpopulated PCBs to the order would be pretty cheap as well, I guess around $1 per panel.
wdfx··on ESP32 Drum Synth Machine
This is very cool. I'm very interested in using ESP32 for MIDI/Audio/Synth projects, I have one of my own on the go: https://doug.lon.dev/fourays ;)

I hope to get confident in doing PCB layouts in KiCAD and manufacturing my own synth modules on a budget. I'm currently a bit stuck on how to get the front panels designed and manufactured, and coupling that with the correct "UI" hardware (pots, buttons, sockets) in order to make the thing assemble correctly.

wdfx··on Hitting every branch on the way down
Some people however see using features like amend, squash, and force push as potentially destructive actions in the hands of a novice, which can lead to loss of not only the author's work but also other people's. Using merge almost never results in any sort of loss and is easier to work with for those who still don't quite understand the risks.
