e_proxus··on GitHub Actions: Ephemeral self-hosted runners and new webhooks for auto-scaling
I really wish the runner agent was written in something more portable than .NET. That choice feels like something purely political because they’re owned by Microsoft. I doubt and independent organization would have chosen it before other excellent choices such as Go, Rust etc.

Currently hosting the runner on e.g. FreeBSD or custom embedded systems is not supported (or even possible).

e_proxus··on TrackerZapper Mac app silently removes tracking parameters from links you copy
Or in this case ”automatically”.
e_proxus··on Show HN: Weather API for non-commercial use
As linked from elsewhere in the thread: https://oikolab.com/
e_proxus··on A single laser fired through a keyhole can expose everything inside a room
My sci-if part of my brain tells me that in 10-20 years we’ll see small box-like devices that you attach to a key/peep hole or perhaps with a built in silent needle puncher that creates a small hole on-demand. Perhaps with a moving laser that would imagine still objects too.

Combine that with AR glasses and you would have a useful pre-breach tool for police/military.

e_proxus··on Chia Coin Miners Are Reselling Used SSDs as New
Your calculations are probably correct, but the whole cryptocurrency fad strikes me as completely ridiculous.

It’s like a farm burning some of their crops to generate a bit of hot air for wind power. Like, you can do it and it gives you that small amount of power but you’re literally destroying the resource and probably cause a lot of waste in the system as a whole.

e_proxus··on Facebook apology as AI labels black men 'primates'
Given the complexity of the solutions employed in this space and the task we’re trying to get them to solve (or perhaps, the solutions we’re looking for problems to) I’m not that surprised.

Taken to the extreme, AI code is essentially something like:

  add(M, N) {
    return M + N + rand();
  }
In addition, being tested with a (in relation to the complete set) very small set of input data.
e_proxus··on Why Erlang?
Nova is an up-and-coming new framework http://novaframework.org/
e_proxus··on Why Erlang?
It’s all about resilience, not about preventing bugs completely. The beauty of it all is that you can skip on a lot of error handling code whose only purpose is to keep the system running. You only need to handle business logic errors. Let’s take a web server as an example.

The way the “let it crash” philosophy is done in Erlang is that you crash individual processes first (e.g. the current HTTP request from one browser). If that keeps happening there’s a counter that crashes the subsystem (e.g. the web file listing component). If that too keeps crashing the whole web frontend might crash, but the node might still be up (e.g. serving FTP or whatnot). And lastly the node will shut down completely if the web frontend keeps crashing.

This way, the rest of the system keeps performing and serving requests even if some parts are not working intermittently.

On top of this you of course have (built-in) logging of all these errors so you can investigate them.

e_proxus··on Why Erlang?
I’ve yet to see a language + framework combination that has everything great from Erlang/OTP.

Scala+Akka might come close, but from what I’ve heard it’s not there yet.

e_proxus··on My House
I can assure you that the allotment areas in Sweden are in no significant way contributing to the housing crisis. That has many other reasons, of which these relatively small areas is definitely not a major one (if one at all).

Sure, some would be prime real estate but I’d rather have a few of these co-ops mixed into the cities than just private housing projects everywhere.

There’s also the similarly named Hyperscript in the same vein: https://hyperscript.org/
e_proxus··on Kim Stanley Robinson: a climate plan for a world in flames
How so? Who controls the economy if not humans?

These rebuttals usually one from a sense of despair, but the system can be changed if we really want it to.

e_proxus··on Kim Stanley Robinson: a climate plan for a world in flames
You can usually open a private tab in your browser, go to google.com and paste the URL in the search field. The first result should be the FT page which when clicked will take you to the article without the paywall.
e_proxus··on Apple explicitly asks employees to merge their personal and work accounts
Wow, what kind of workplace did you work in?

Here in Germany I think gathering many of these facts would simply be illegal.

e_proxus··on Tesla Announces a Humanoid Robot “Tesla Bot”
Risky, but maybe it would even be good PR to try to match the dance and see the robot fall over just to point out how far they actually have come in 30 years.
e_proxus··on Hash collision in Apple NeuralHash model
Wouldn’t it also just be possible to turn a jailbroken iDevice into a CSAM cleaner/hider?

You could take actual CSAM, check if it matches the hashes and keep modifying the material until it doesn’t (adding borders, watermarking, changing dimensions etc.). Then just save it as usual without any risk.

e_proxus··on TikTok requests access to devices on local network
Nearly every app?! What apps do you actually use? I’ve only ever seen the prompt a few times, and always for pretty obvious reasons (UniFi, Prompt, VLC, etc.)
e_proxus··on 1Password 8 will be subscription only and won’t support local vaults
I was rather alluring to the different mobile apps which all seems to often be developed by various unknown developers (some closed source) instead of the core developers of the main project.

I too would trust the core of e.g. Syncthing or pass.

Making it all work on mobile is a completely different story though. I myself can’t do without mobile access to my passwords.

e_proxus··on 1Password 8 will be subscription only and won’t support local vaults
For me it’s more about trust. I’d rather trust a company with decades of experience this area than a bunch of random developers that published different unvetted apps on various app stores.

And technically, Syncthing doesn’t really seem viable on mobile last time I looked (and also has the problem of 3rd party apps instead of official ones).

e_proxus··on GAN-generated facial images that are capable of impersonating multiple IDs
Yes, Face ID uses infrared depth sensors so it shouldn’t be possible to use just a printed image. You might be able to fool it with by printing with some strange material that fools them, but I don’t see the point with coming up with such an advanced technique. Then you might as well just print a 3D model.
e_proxus··on GAN-generated facial images that are capable of impersonating multiple IDs
Unless you can either produce the correct 3D surface itself or fool the sensors somehow I don’t see how the inner implementation matters.

Or do you mean attacking the inner network somehow from inside the system?

e_proxus··on My small revenge on Apple
No, you got it the wrong way around. This puts privacy on the table. This way, I can choose to use Sign In with Apple.

If the only other options you provide are Google or Facebook, you (as an app developer) clearly doesn’t care that much about privacy.

Apparently Apple doesn’t feel that any other providers care enough. That’s why they’re mandating the use of their privacy-focused solution.

e_proxus··on Home Assistant iOS app adds local push notification support
Turns out a free IFTTT account together with a web hook "if" trigger and a notification "then" action works like a charm.

e_proxus··on Home Assistant iOS app adds local push notification support
Tangentially related: I frequently start long-running shell commands and go make a coffee. Is there an easy way to send a notification from my Mac to my iPhone?

You would think it would be a use case for Automator or Shortcuts but I don’t think it’s possible?

There are various apps that can do this but everyone I’ve found is very enterprise oriented and fairly expensive. I just want to send local network notifications to my phone once in a blue moon… (bonus if it would work while I’m talking a walk outside the range of my network too, but it’s not that important).

e_proxus··on Difftastic: Syntax-aware structured diff tool
Couldn't something like this be based on e.g. Sublime's syntax definitions? Then it would work on all languages/formats that had such a definition.
e_proxus··on Don't encode POST bodies like GitHub Copilot, use URLSearchParams
So it will be self-reinforced to get worse and rot over time? Since surely all code that used Copilot will be slightly worse than code without (extrapolated on the assumption that Copilot is wrong some of the time).
e_proxus··on Protein found in robins’ eyes has all the hallmarks of a magnetoreceptor
Brains are incredibly adaptive. There are tons of experiences where people have had diminished or lost access to one of the senses and recovered surprisingly well.

I had a colleague once who had a stroke and described his vision afterwards as looking though splintered glass. After a while, he explained he didn’t perceive it anymore and that his brain just decided to “workaround” the issue making new connections where needed.

I think having some “sense” of magnetic fields could be very subtle, like just a feeling of which direction you’re facing when you’re turning around (you could argue you already use the position of the sun this way, subconsciously).

People into body mods who get a magnetic implant often describe it as a sixth sense [1].

e_proxus··on Do you really need Redis? How to get away with just PostgreSQL
You have to solve these things with a job queue system written in any other language or using any other databases as backends too though.
e_proxus··on EA got hacked and games source code leaked including new game Battlefield 2042
With the code it should be easier to fake a client, download and decode that configuration. Hopefully some further experiments can be done with access to the real source.
e_proxus··on Language learning with Netflix
Usually most companies are okay if you have titles or names like “X for Netflix”. Some even explicitly state that they prefer that. It’s also a rule on the Apple App Stores that you can’t have a name like “Netflix X” to avoid confusion.
