johnr2··on Shopify CTO: our platform is now handling Black Friday level traffic every day
> Unless there’s a reason we can’t repeat the famous infrastructure jobs programs from a century ago

That had positive effects in the USA, but in Europe the economic woes of the 1930s led to WWII.

> Emergency measures being valid for the duration of the emergency would be pretty straightforward.

Deciding when the emergency is over is less straightforward than a fixed time period. A government that wanted to extend the measures indefinitely would just claim there's still an emergency.

This may be because a hungry panda is unlikely to eat you.

> Why do sites like nytimes get a free pass with their paywalls?

I've never encountered a paywall on the NYT links on HN and I'm not a subscriber. I'm guessing the complaints here are from people who only have access to browsers with no means of blocking (or ignoring) JavaScript.

johnr2··on The accusations were lies, but could we prove it?
> I would love to read this, but keep getting blocked by paywalls.

Have you tried blocking JavaScript? It works fine here in Firefox with NoScript and in Dillo (which has no JS support).

The link works here in Firefox with NoScript, also in Dillo (no JS support).

johnr2··on Windows has a new wormable vulnerability, with no patch
> Perhaps one day unsafe programming languages will be forbidden to use.

That would mean ruling out a whole lot of performance-critical software (including that written in unsafe Rust). Be careful what you wish for.

It's probably a lot lower than the cost of never implementing the software in the first place.

To dehumanise those they're applied to so you can say bad things about them without feeling guilty.

It has the opposite effect on me. I feel like I'm being patronised. Maybe it's generational (I'm old).

johnr2··on PipeWire 0.3 – JACK compatibility layer with comparable performance to JACK2
> Jack, while incredibly powerful has been a huge hurdle for pro audio on Linux.

For me JACK was a huge step forward. After 25+ years of recording on tape, JACK allowed me to switch to computer based recording ~14 years ago. It did away with a lot of the arbitrary restrictions on what connections were allowed in the audio software that was around at the time (and which made me unwilling to switch until that point).

johnr2··on Why Germans won’t heat their homes even with free electricity?
> You're claiming that when mostly people say "electric heating" they are specifically excluding heat pumps?

No, just pointing out the usual definition of electric heating. A heat pump doesn't necessarily even use electricity. The mechanical power for the compressor (assuming a refrigerant based heat pump) could come from anywhere.

> do it all inside one program (e.g. a DAW or something a bit like it) is easier for most people (no complex state management) and closer to their pre-existing mental models.

This may be a generational thing. As someone who learned recording in traditional analogue studios, I find a modular approach using JACK to be much closer to my own mental model.

johnr2··on Why Germans won’t heat their homes even with free electricity?
> Electric heating via heat pump is ridiculously efficient

Strictly speaking that's "electrically assisted" heating. What most people refer to as electric heating is the conversion of electricity directly into heat, eg. by a resistive element.

You can still use Linux, but you won't be able to use those plugins.

> I know a fair number of privacy-concious people, and not one of them have any sort of verifiable control of their hardware.

I have a reasonable level of confidence that my use of wirecutters and/or soldering iron gives me enough control over this kind of thing. It's impractical on a smartphone, but I solve that by not owning one.

> I don't know any production-grade sound cards that have Linux drivers (my RME ADI-2 Pro certainly doesn't)

Most of the RME HDSP/HDSPe PCI/PCIe cards work on Linux using the ALSA snd-hdsp or snd-hdspm drivers. The ADI-2 can use the generic Linux USB audio driver AFAIK.

johnr2··on Fedora Muscian's Guide
>this is completely wrong. internal audio interfaces tend to be worse than external audio interfaces. what internal soundcard can compete with a universal audio apollo?

Audio engineer here. It isn't wrong. PCI and PCIe cards with external AD/DA converters have better performance, reliability and higher channel counts. Eg.: https://www.rme-audio.de/hdspe-madi.html

64 channels in, 64 out. Works fine on Linux.

johnr2··on Reasons not to become famous
> You have unemployment and more than enough time to find a new job. And let's say you don't find one, the state will still give you enough money for you to survive.

Quite a few commenters on this forum live in parts of the world where that is not the case. It's certainly not the case for the majority of the world's population.

johnr2··on Where Have All the Schematics Gone?
For many years my purchasing policy for test equipment was "no schematics, no sale". I still try to stick with that as far as possible, but it means I don't buy much new equipment.

> Could the tin whisker problem be solved by simply reflowing circuit boards every 5-10 years

Apart from logistics, many components have a hard time surviving the heat of soldering during original manufacture and may fail on subsequent reflowing.

Lead free solder typically has a melting point around 35C higher than tin-lead which exacerbates the problem.

johnr2··on Where Have All the Schematics Gone?
> Funny, the simplest thing to do there, and relatively cheap, is to lacquer the whole device after it's soldered. This is done on military grade hardware - or even tougher conformal coating.

That helps avoid tin whiskers, but those aren't the only problem with lead free solder. It doesn't flow as easily as tin-lead, so dry joints are more common. It's relatively brittle, so it's more susceptible to vibration and thermal fatigue. Melting point is higher so components are more likely to be damaged during soldering.

Military hardware is exempt from RoHS for good reason.

The default compilation option is PulseAudio, but some distros (eg. Debian) also enable ALSA support. On OpenBSD Firefox uses sndio.

You're right that computers have saved huge amounts of energy compared with the things you mention. My point here was that even more could be saved with a bit of thought about efficiency in programming.
