I understand trimming input fields is typically a useful default, but in this case this prevents me from searching for a space. So maybe it'd be worthwhile to add a `if (trim(str)=="") return str` exception or something similar?

Imagine my face when I had to take periodic backups of stateless, immutable read-only filesystem, non-root containers for "compliance".

To be honest, I would even go further: if you think certification equals security, you are even more lost.

So many controls are dubious, sometimes even actively harmful for some set-ups/situations.

And even moreso, it's also perfectly feasible to pass the gates with a burning pile of trash.

Can confirm. Have encountered many on-prem and lift-and-shift solutions with no automated means of updating certs. The worst contenders are usually 1) executables on windows server (version 2012, of course), 2) old, obscure or very outdated database servers and 3) custom hardware firewalls. They are the worst.

To make things easy they usually all use different cert formats as well, requiring you to have an arsenal of conversion scripts ready.

We have an OCR job running with a lot of domain specific knowledge. After testing different models we have clear results that some prompts are more effective with some models, and also some general observations (eg, some prompts performed badly across all models).

Sample size was 1000 jobs per prompt/model. We run them once per month to detect regression as well.

Do you mean attacking a second country in the top 10 oil/gas reserve ranking in mere weeks, while threatening to invade a third?

The A3B part in the name stands for `Active 3B`, so for the inference jobs a core 3B is used in conjunction with another subpart of the model, based on the task (MoE, mixture of experts). If you use these models mostly for related/similar tasks, that means you can make do with a lot less than the 35B params in active RAM. These models are therefore also sometimes called sparse models.

Exactly there's so much stuff you simply cannot configure otherwise. For example disallowing applications to take sole ownership of a mic, in-detail power plans, etc. If they remove the old control panel, your machine basically becomes unconfigurable.

Had to search a bit, but here's a demo page: https://maplibre.org/maplibre-gl-js/docs/examples/display-a-... Can be compared with: https://maplibre.org/maplibre-gl-js/docs/examples/display-a-...

In that example I saw this in the console:

    before - 2.41+26.29+24.87+71.28+59.2+77.57 - 261.62kb
    after  - 2.45+22.4 +22.66+60.6+51.99+77.57 - 237.67kb

So roughly a ~10% compression improvement, neat!

For those interested in browser differences, on my machine:

Firefox

  AoS: 2951.00ms
  SoA: 1624.00ms
  Interleaved: 1961.00ms

Chrome

  AoS:         2133.30ms
  SoA:         884.30ms
  Interleaved: 1457.60ms

Seems the interleaved being slower is consistent across browsers!

Additionally, solar panels can become too hot and that reduces their efficiency. Also, deserts are famously known for dust. Since it rarely rains, you get a dust buildup, further compromising solar efficiency in deserts.

I'm not saying that deserts are a bad place for solar. What I'm trying to say is - it's often worse than people think and it requires special infrastructure.

Interesting, this is the first time I've come across using a FFT for collision detection, and now that I think about it it really makes sense. Thanks for the insight!

If I can get in once, I can do it again an hour later. I'd be inclined to believe that dumb recycling is not very effective against a persistent attacker.

Mhm, this is one of these cases I'd prefer a benchmark to be sure. Checking %2 is very performant and actually just a single bit check. I can also imagine some cpu's having a special code path for %3. In practice I would not be surprised that the double operand is actually faster than the %6. I am mobile at this moment, so not able to verify.

What I really don't like about thread/matter is that it is becoming the de-facto standard that thread border routers are connected to the internet.

This will in time result in IoT devices that actually mandate this connection (it was already stipulated in a recent version of the protocol). The end result will be that a new protocol was created, but rather than devices being able to run on their own, we end up with beds in heating mode, ie. the garbage we were trying to avoid in the first place.

So for me, zigbee it is!

It would be interesting to see a JDK happen where all these backwards compatibility quirks are ignored, and raw performance is chased instead. A thousand of these little gains can really add up over decades. In this case there was a workaround it seems, but it feels a bit contrived to me ('missing fields are ok'?).

The moment you put TOTP in Bitwarden it is no longer a 'second factor'. Pretty bad security advice to be honest. Better to use hardware tokens or a secure phone (with enclave) instead (never SMS though).
