nyanpasu64··on Diagnosing video signal loss on Wii and GBS-Control
I don't have any power isolators, UPSes, or similar. My first thought was to swap the power supply or console, but I don't have an easy way to do either one without paying for one-time components I won't have a good use for afterwards (I could sell a Wii on eBay, but have never sold there before).
nyanpasu64··on 2 GHz Active Probe
Is the analog Nyquist frequency of the signal 0.5x the digital baud (effectively sampling) rate?
nyanpasu64··on Diagnosing video signal loss on Wii and GBS-Control
Author here. Unfortunately after removing the wall switch, I found a newly installed mini-fridge would cause signal dropouts sometimes when the motor started or stopped. Moving it into an adjacent room reduced the frequency of dropouts, but I still got them periodically (and can no longer hear the mini-fridge to tell if dropouts are correlated). A few weeks ago I unplugged the mini-fridge because I barely used it and it had filled with ice. Since then I have not gotten any dropouts (aside from static shocks in my room), but haven't played my Wii long enough to know with confidence it won't happen again.
nyanpasu64··on Making iron gall ink from oak galls
That was just a quick experiment (not fully grounded in chemistry theory) to see what would happen, since my ferrous sulfate wasn't arriving until a day later.
nyanpasu64··on Making iron gall ink from oak galls
I looked up electron donors in Wikipedia and apparently those serve as reducing agents. I was confused how it would oxidize wood, so I looked up 'iron-catalyzed oxidation' and found an article (https://link.springer.com/article/10.1007/BF00351367) which claims oxidizing iron produces free radicals and hydrogen peroxide which subsequently eats the wood. I also came across https://en.wikipedia.org/wiki/Ferrous in my research....chemistry is complicated.
nyanpasu64··on Ultrasonic investigations in shopping centres
I think the dogs can hear our induction stove with ultrasonic whine, but somehow my cat will sleep blissfully in a room with a VGA CRT whining from 30-80 kHz (perhaps quieter than the stove), and used to sit in front of a CRT TV whining at 15.7 kHz so loudly I couldn't stand it without headphones.
nyanpasu64··on Ask HN: What was your most humbling learning moment?
"B [roll] for a G&R concert" sounds like a joke about RGB in little endian.
nyanpasu64··on [dead]
I was interested until the homepage referenced AI models and the app asked me to login with a Github or Ethereum account. Also why have you submitted 34 links since 4 days ago?
nyanpasu64··on Introducing Copilot+ PCs
I'd join, but Metro Internet Explorer crashes whenever I try to message, and the tablet battery won't last me the trip to the club...
nyanpasu64··on Short Stack: World’s smallest Nintendo Wii
The stock GC controller ports place the contacts next to each other, rather than at different depths, so they won't connect controller pins to the wrong port pins or short pins together when partially plugged. (I do suspect the ground and/or power pins may be longer than data lines, to connect first.)
nyanpasu64··on How does the classic Win32 ListView handle incremental searching?
Also if you accidentally click a folder, or type-to-find a folder to save in, it will overwrite the save filename.
nyanpasu64··on How does the classic Win32 ListView handle incremental searching?
One annoyance with incremental search in file views is that if you press the wrong key, you have to wait some time to begin typing again from the beginning, unless you press Esc to clear the search history... except in file picker dialogs, it instead closes the dialog altogether!

nyanpasu64··on Comparing Desoldering Tools
The Pinecil is cheap cheap and good enough (if you have a suitable power supply, which many people don't).
nyanpasu64··on WinBtrfs – an open-source btrfs driver for Windows
In a separate occasion, I also got that issue (but worse). I once marked a NTFS folder as case-sensitive to help root out all case mismatch bugs (to get a C++ project eventually building on Linux), but then Visual Studio and CMake started spitting out "file not found" errors even for the correct case! I had somehow produced a "cursed" folder that could not be used for building code until I copied (not moved) its contents to a regular case-insensitive NTFS folder.
nyanpasu64··on Is the frequency domain a real place?
> To turn the Hadamard matrix in the nicely-ordered flavor showcased earlier, we need to sort the rows based on their sequency. I’m not aware of an algorithm more elegant than counting the number of zero crossings

By staring at the matrix, I guessed a pattern and algorithm already known according to https://en.wikipedia.org/wiki/Walsh_matrix:

> The sequency ordering of the rows of the Walsh matrix can be derived from the ordering of the Hadamard matrix by first applying the bit-reversal permutation and then the Gray-code permutation:

nyanpasu64··on WinBtrfs – an open-source btrfs driver for Windows
One time I accidentally ran a Visual Studio build in a btrfs git clone rather than my main NTFS drive. By the time I noticed and cancelled the build, there were two folders with an identical name but different contents, which I had to delete the folder name twice. I'd say the driver has issues with concurrency.

Which comment about Meson are you referring to?
nyanpasu64··on HP Disables Printer Functionality Until You Install the HP Smart App
I looked up the model M110w and found:

> This printer is intended to work only with cartridges that have a new or reused HP chip, and it uses dynamic security measures to block cartridges using a non-HP chip. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. A reused HP chip enables the use of reused, remanufactured, and refilled cartridges.

This is the future of printers...

nyanpasu64··on JITX – The Fastest Way to Design Circuit Boards
Does this create a problem if schools prevent students from posting their projects publicly (because it would allow other students to "cheat" and look at previous students' solutions), and such projects are no longer considered open-licensed here?
nyanpasu64··on Hotdoc Documentation Framework
The styling looks familiar from Meson's website at https://mesonbuild.com/, and checking Inspect Element on Meson's site reveals hotdoc references in the HTML source. Though I still don't know if it's better than other docs/website frameworks.
nyanpasu64··on How photos were transmitted by wire in the 1930s
Breaking an image up into lines is similar to how television cameras/displays and raster scan CRTs operated (IIRC TV dated back to the 1920s?), though wrapping the image on a drum was clever and not found in television technology. I wonder how they synchronize lines between the transmitter and receiver though (all video standards have hsync pulses, while I didn't see any such here). I'm not sure how fax machines worked/work either.
nyanpasu64··on Multi-Threading and Mutation
In the article, wouldn't the runtime of the "join operations" step limit how much performance can be gained by parallelizing computation (due to Amdahl's Law as you brought up)?
nyanpasu64··on The Secret Life of XY Monitors (2001)
Sadly with CRT monitors (at least today) there's a tradeoff where at low brightness (black level) settings, dark areas of the image are underexposed, and at high brightness even pitch-black emits a bit of light. The ideal solution would be a nonlinear gamma-like curve where dark areas of an image have a higher slope than the rest (but without decreasing the slope of whites compared to mid-tones).

Default-on telemetry as well. I'm reminded of Balena Etcher phoning home with the names of ISO files you flash, which leaks the IPs etc. of which users are creating Tor/Tails bootable USBs: https://gitlab.tails.boum.org/tails/tails/-/issues/16381#not...

nyanpasu64··on A lock-free ring-buffer with contiguous reservations (2019)
Chapter 7 doesn't test if performing loads on a reader thread makes a writer thread any slower to perform relaxed writes. Does a concurrent reader slow down writes or not (the LMAX Disruptor relies on variables with one writer and many readers, and claims it's fast), and does it depend on the CPU's cache coherence protocol?
