edpenzon We can do better than line-buffered output

One more thing to consider is atomicity of write interleaving to the same pipe. Say you fork two unzips in the terminal like `unzip a & unzip b`. With naive line buffering the outputs mix cleanly, but if aggregating multiple lines per write the chunk size needs to stay below PIPE_BUF for this to stay true.

edpenzon Show HN: E-Paper 7-color display showing the current weather

The black does have a purpleish tinge on my panels, but the other colours don't. Overall it's pretty low contrast and saturation, and unable to reproduce cyan or fuchsia even with blending through any kind of blending, which makes certain things like sky and water come through poorly.

I made a palette for colour space conversions for reference: https://imgur.com/a/2vgFsT4

edpenzon Show HN: E-Paper 7-color display showing the current weather

The similar project I'm working on is looking like it'll get about a year of battery life with a typical 18650, the 5.65" version of the display and run off an ESP (refreshed once a day).

edpenzon Podman 4.4

Best solution I've found is installing the v4.3 .debs from Debian bookworm. Only caveat is you need to do some of the dependencies manually as well.

edpenzon Intel says one of its 13th Gen CPUs will hit 6GHz out of the box

The counterintuitive trick I've used for my 5900X is to increase the minimum fan speed up to around 60% or so. It makes the base volume very slightly higher, but avoids it constantly ramping up and down through the 50% zone which is what I found the most annoying/noticeable.

edpenzon $55 board turns a Raspberry Pi CM4 into a router

There are some real steals if you dig deep enough. Case in point the Xiaomi 4A GbE:

  * $30 (not missing a zero)
  * OpenWRT support
  * 128MB RAM
  * 3 gigabit ethernet ports
  * 802.11ac Wi-Fi

Sure it's not going to compare to a full Raspberry Pi (tiny flash, no USB, no video, no expandability), but for plain routing it's fantastic value.

edpenzon Making pip installs a little less slow

pip-compile [0] is the best tool I've found for streamlining dependency resolution, but it may not provide any benefit for one-shot installs.

edpenzon Making pip installs a little less slow

The most efficient workflow I've found for pip so far is something along the lines of:

  pip-compile # resolve and pin the dependency tree
  grep '==' requirements-pinned.txt | xargs -n1 pip wheel  # build every wheel in parallel
  pip install *.whl  # install the pre-built wheels

It may not avoid all the slowness, but when nicely integrated into a build/CI system it can avoid suffering it more than once.

edpenzon Ask HN: Have you created programs for only your personal use?

> A secure-but-readable password generator

I love pronounceable passwords, but there's research indicating that such generators typically produce lower than expected entropy. Do you mind sharing what algorithm you use?

Made this for (and have not touched it since) my last job search.

Design-wise I'd like to dial back the animation and minimalism a bit, and bump the contrast. Also have been thinking about adding more written content like blog posts or technical whitepapers.
