It seems like it doesn't do this for Code 128 (possibly because it is variable-width?). It definitely works with EAN13 though - I tried it locally using only the TTF file.

Barcode fonts have been around for ages. But what's cute about this one is that it can calculate the EAN13 checksum on its own.

This isn't without downsides though: As somebody with a niche technical hobby, it is hard for me to order from many suppliers because they understandably don't want to deal with consumer protection laws and thus exclude B2C transactions outright ("Verkauf nur an Gewerbetreibende").

I would be fine with waiving my right to returns but this is not possible on purpose, so my only options are to shop somewhere else (often not possible) or found a company (not possible because it would be Liebhaberei - "Running a company without intent to make profits").

New comment by ahlCVA in "Welcome to the Strip Mining Era of OSS Security"

Whenever one of these vulnerability apocalypse posts comes along I cannot help but think of the Litany of Gendlin:

  What is true is already so.
  Owning up to it doesn't make it worse.
  Not being open about it doesn't make it go away.
  And because it's true, it is what is there to be interacted with.
  Anything untrue isn't there to be lived.
  People can stand what is true,
  for they are already enduring it.

I cannot wrap my mind around why people think finding vulnerabilities is bad. The code already was broken before somebody published the vulnerability. The difference now only is that you know about this.

Imagine somebody finding a flaw in a mathematical proof and everybody being sad because a beautiful proof got invalidated rather than being glad future work won't build on flawed assumptions.

I get that the rate of vulnerability discovery can be a burden, especially for people doing FOSS in their spare time, but the sustainability problem with that has always existed and only gets exacerbated by the vulnerability stuff, but the latter isn't the cause you need to make go away.

New comment by ahlCVA in "The USB Situation"

Apple implements the USB-C/USB PD specs to a t and is unforgiving if you don't do either.

At work, our quick test for if a device implements USB PD correctly is to plug it into an Apple power supply (optionally with a PD protocol sniffer in line). If it doesn't work (either no/intermittent VBUS or the wrong VBUS), it's always been the case that the device is doing something wrong.

It can be annoying but strictly speaking their fault.

You're probably taking the wrong painkiller
