ctrl+f "Exclusively for Mac". There is one hit (though there is another similar message that is not cursive).
Yes, that’s the point. Profit is more important than human well-being, beauty, culture, or anything else. It’s why I love the moderation of Europe, though even the EU is over-capitalized, hence I chose Ukraine.
Funny I always considered the impetus of Encryption at Rest to be the "left my laptop in the airport scenario". Or, maybe, "Where'd that CD with all of the medical records go?"

Originally, I never felt that the EAR issue was that germane at data centers, since you're mostly protecting against someone backing through the loading door with a truck and stealing trays of drives.

The disposal issue is valid, that was just something we were diligent with using a secure disposal service.

Key management has always been an issue. Since no one wanted to be there when the machines spooled up after a glitch at 3am to type in a password to open the volumes. Everything else is basically locking the file cabinet drawers and taping the key to the back of it.

Nowadays, it's different. Its more ubiquitous. Encrypting a laptop is a mouse click, and painless after that. Cloud providers have the infrastructure to manage it at their level.

I'm still now sure what the solution is for a "self hosted" infrastructure. Hardware key modules are still pretty expensive. I haven't (not that I've looked at all recently) seen a writeup of how best to set of encryption on those 4 Dells my friend has racked across the country in Georgia (though even modern machines have some level of volume encryption I think).
Just wondering, in light of the downsides including this, are there benefits to these devices, like apple TV, fire tv, etc. over a mini pc, like a beelink s12 pro?

I understand that most consumers aren't aware of the alternatives or think they might be more convenient, but I'm looking to get personal perspectives from "hackers".
I couldn't quite connect all the dots as to why this is better. Something I do understand is summing numbers close to zero before numbers of larger magnitude away from zero produces a more accurate sum because floating-point addition isn't truly associative.

My best guess is that this reverse-z convention keeps numbers at the same scale more often. I think it's important about the same scale rather than near zero because the relative precision is the same at every scale (single precision float: 24 bits stored in 23 bits with implied leading 1 bit). If the article is trying to say that numbers near zero have more relative precision because of denormalized representation of FP numbers it should call that out explicitly. Also the advantage of similar scales is for addition/subtraction there should be no advantage for multiplication/division AFAIK.
> Using algorithms&data structures trivia in interviews

I never said trivia. By definition, trivia is stuff that is not important. I interview for things that are important to the work we do, and I give plenty of hints along the way to give a candidate a chance to show their reasoning abilities even if they have gaps in their knowledge or memory. This is what critics of algorithm interviewing conveniently ignore to make the interview seem unfair and unreasonable.

If you had a bad interviewer I'm sorry to hear that. Formal interview training in places like Google explicitly includes how to hint and unblock people effectively, and hiring committee feedback-on-feedback can instruct interviewers how to be more fair and better reflect the candidate's potential. Maybe your interviewer did a bad job and later received that feedback, but it had already soured your perception of algorithm interviews.

It's also a total myth that candidates are completely rejected because of one bad algorithm interview. If you have a day of five interviews, your success is not an AND() of the five, but it's also not an OR(). Whoever looks at the feedback weighs the various positive and negative signals to determine if it's a fit for the role. Skills in some areas can outweigh skills in other areas. Algorithms are one of those areas for a reason but it's still only one area and probably only one or two of the five or more interviews people will do.

If you know a better way to interview for these skills before hiring someone, please tell the rest of us and change the industry for the better. Until then, this seems to be the best we can do.

If your organization has very different needs, you can interview your candidates however best meets those needs. I know my organization needs algorithms and data structure skills, not just trivia but actual fundamental skills that generalize to novel problems we encounter along the way, and I'm going to keep interviewing for those skills. It's still just one interview out of several, and we've hired people that totally flunked my interview, so I'm not even gatekeeping, I'm giving the hiring team the signal they asked me to give them and the rest is up to them.
The inability to get a TLS cert is an issue. I've been working on getlocalcert [1] as a free subdomain service for local networks. You get a valid domain, you can get a Let's Encrypt (or other ACME DNS-01 provider) cert. But you need to provide your own split DNS locally to resolve addresses. It's intended to fill the gap between paying for a domain or using a free domain service full of abuse.

Because you need to provide DNS locally, it's useless for the common abuse scenario (spam, phishing, illegal content). Unlike other free domain providers, I have never received an abuse notification.

I got on the public suffix list in the last few months. Lots more features I'd like to add, but my attention has been elsewhere.

The dropping hyperthreading is interesting. I'm hoping x64 will trend in the other direction - I'd like four or eight threads scheduled across a pool of execution units as a way of hiding memory latency. Sort of a step towards the GPU model.

The camera and the blog posts are lovely! Beautiful and inspiring work. Is there any way you could publish an RSS or Atom feed? I'd love to follow your blog in my feed reader (NetNewsWire, fwiw).
I think part of it is regression to the mean. Like, your body heals itself naturally from many things. Say you get a cold. For most people at some point it'll heal. If you have a group of people with the cold, and try to determine how effective vitamin C or zinc or COLDKILLER777 is, you can't just give it to them and say "look, they're healed", because they would heal naturally. You have to prove that they feel less symptoms or heal faster than people in the same circumstances that don't receive the same molecule.

I also remember some similar stuff for back pain and surgeries. In that context people were seeking treatment when their back issues peaked, and the question was, when you take the cohort of people that had back surgery and the cohort of people that didn't, did the back surgery make a difference? Because some people healed naturally.

I don't know if this is true in that specific context, but to take a more pedestrian one, I've had lots of small cuts, burns and things like that during my life, and they all healed.
Tbh, that workflow is also how you approach proper visual CAD programs. When I draw something in Solid Edge, I create sketches, extrude, etc until I've achieved roughly what I want, then I take measurements and set them as constraints in the model and it'll adapt accordingly.

And if I'm unsure about a measurement, I can just export a few models with slightly different values, 3D print all of them and try which works best.

I set forth on giving a challenge to myself: Understand the mathematics, create in C, use raylib, make it as quickly as possible.

Inspired by really alot of cool demos and explanations on a really cool topic: fourier representations of signals, I decided my project of immediate focus.

Let me know if you found the visuals interesting.

Any suggestions about the code base are highly requested. What should I work on next to sharpen my Julia skills.

An argument for integrating molecular dynamics data into proteomic ML
I've been using CUE for GHA definitions. I find it much more readable and writable. Dhall syntax is not for me and development has slowed while CUE's has picked up. Starlark is the other config language I see gaining some adoption.

Here is the same GHA in CUE

// top-level config
name: "Node.js CI"
on: {
pull_request: branches: ["main"]
push: branches: ["main"]
}

// jobs loop, unified with below
jobs: {
for _,ver in ["20", "21"] {
"buildNode\(ver)Job": #job & { _ver: ver }
}
}

// common job config
#job: {
_ver: string
"runs-on": "ubuntu-latest"
steps: [{
name: "Checkout"
uses: "actions/checkout@v2"
},{
name: "Use Node.js"
uses: "actions/setup-node@v2"
with: "node-version": _ver
},{
name: "Install Deps"
run: "npm install"
},{
name: "Run Build"
run: "npm run build"
}]
}

`cue export gha.cue -o gha.yaml`

There are many ways to make this more interesting. Imagine extending this to configure the OS or matrix builds. The most useful might be to import the GHA schema to ensure you are writing "correct" workflows before you ship them.

'The guy above' is also me :) And yeah, I get it. I guess the thing I'm trying to get at by extension and example is just how hard a problem this is, and maybe also that the formulation given assumes LLMs have a level of control over human behavior that not only doesn't exist but in the general case sort of can't since the LLM's user is always free not to take its advice. (At the very least, if humans have no option but to follow LLM instructions, something has gone much more badly wrong than the risk of there being poor instructions...)

In general, I think it's a good example of the kind of social problem tech can make a lot worse but no better: when a society has lost its grasp of epistemology, multiplying the amount of information available, at a net decrease in quality and reliability, merely multiplies the scope of the problem.

I don't find it shocking, because these institutions have never cared about these individual issues, they just want to be anodyne and acceptable to their target audiences. In a time of turmoil, it's hard to be find that universally acceptable stance.

I think the preponderance of evidence points strongly to these phenomena being purely mental - in particular the vast majority of conscious behaving entities which we encounter on a regular basis are physical objects with certain properties (having a brain is the big one) and what we know about physics, biology, computation, and neuroscience makes a pretty compelling case that the physical object in question (the brain) is intimately, probably one to one, connected with the phenomenon we identify as the entity. It would be very strange if we found evidence of non-material entities given this context. And in the case of the self-transforming machine elves we very clearly have a compatible alternate hypothesis: they are generated by the brain which we are mucking around in with chemicals which are known to disrupt its behavior.
I once seen a bug in a Django App which caused similar issues. Basically the app often returned a HTTP no content for successful calls from AJAX requests. So someone had DRYed that by having a global NoContentResponse in the file. The problem was that at some point in the Django middleware the users session token got affixed to the response - effectively logging anyone from that point on in as another user.
I believe the first of these I encountered, years and years ago, was a photoshopped cover reading “Harry’s a Pothead and the Sorcerer’s Stoned”. Can’t pass up either near-reference to weed with so few words to work with.

I think part of medicine is that, but part of medicine is trying to keep you alive despite your body. Or maybe what I'm arguing here is the "body healing itself". But for example, if you have autoimmune disease, or allergies, you want the body to slow down and take it easy because it's harming itself.

>Although iron ore is plentiful, it is expensive to refine and smelt

Might explain why the land around the Lonely Mountain was unforested*. This is what happened in ancient Greece -- deforestation largely due to charcoal production for smelting iron. Topsoil got eroded and it still hasn't recovered today. Prior to metallurgy, Greece was densely forested, and must have had some biggish trees, judging by the construction of temples etc.

* IIRC. Also a fire breathing dragon taking up residence probably didn't help.
I mean, two authors of the paper are pretty well established in the field already

IO's diameter ~3600km

Avg distance to earth ~628m km

Apparent diameter is ~5 microradians or ~1 arcsecond

Similar to imaging a marble 5mm in diameter from 1km away.

It's 642 light years away.

It's apparent diameter is .2 microradians, or approximately a red blood cell from 35m away.

I had this issue of needing to control Docker containers in a VPS, without sharing access to the server itself. It seems like it will be easy to create a simple web service that can communicate with the ht API, list my containers, show me the stats, and restart containers if I want to. I can manage all security in the web service.

> I love the constant flex of their tiny acceptance rate. "We only accept 1% of applicants. Btw everyone should apply!"

I've seen this mindset among people promoting open positions at desirable companies that don't hire often. In most cases, applying is a waste of time because the company already made its decision to fill the position with an internal candidate.
Find the filings, and read them. And understand what a limited partnership is, what the general partner does, and why saying "he owned 75% of the fund" is nonsensical. He didn't "own the fund", the new guy doesn't "own the fund". He was acting as GP and now another guy is acting as GP, in both cases through another entity. The structure of OpenAI isn't any more opaque than any other reasonable sized business and there are reasons for additional entities, it's not all about obfuscation.
> Rewrite every software, so that every programs handle their own private keys ? Yeah, that's a nightmare, not gonna happen.

PCI 4.0 disallows using Full Disk Encryption to fulfill its encryption at rest requirements, because it demands a finer-grained encryption authorization model. For applications subject to PCI 4.0 compliance, my clients have to encrypt beyond the application level, and down to the service account level used by the application (most of these applications use multiple service accounts for representing teams that use the applications), with different files encrypted for different authorization groups.

There are very few enterprise scale solutions addressing this at the moment, and the stopgap I've seen is indeed the application teams are resorting to handling their own keys if the enterprise doesn't offer a finer-grained solution. The QSA's don't yet understand how seismic a shift this is, nor how inadequate the assumed authorization schema is for the many edge cases out there that will be unable to adopt the assumption a single key for a single group is sufficient to model all use cases. It will be a little messy until folks sort through the edge cases coming down the pike.
The rest of the conversation was mostly uneventful, I did explain it but got told that it was the smallest dosage available. As for the doctor personally he mostly just acted like it was a misunderstanding and not actively not paying attention to what I was clearly saying, but I'd have to say that's a pretty incredible lack of listening/language comprehension for a native english speaker with a college degree. I sure didn't trust that doctor ever again to be paying attention or properly respond to my symptoms if he could hear the exact opposite of what I said.

And as for dose, it was a medication measured in micrograms -- I'd have to be able to carefully measure microgram amounts and put them back into new capsules, it wasn't very realistic. I wound up finding alternatives on my own.

As an aside, I actually have FAR worse stories of GI doctors being incompetent and careless, that one just seemed the most relevant to the topic there.

One other funny one seriously went like:

GI Specialist Dr., "No, you can't really be feeling pain there, the intestines don't have any nerves"

Me, "So why did you say I needed to be sedated for my colonoscopy because it would be too painful otherwise?"

Dr, [angry response about if I want to just argue or let him do his job]

If you can't tell, I soon switched doctors after. But overall that sort of encounter, or things like even violating their own medical association's recommendations such as with prescribing PPIs and Antibiotics simultaneously to a patient already at higher risk of c. Difficile or more than one doctor not being aware of which painkillers are NSAIDs (Yes, really! One GI and one Urologist) has really reduced my trust in specialists, at least in Texas. They so, so, so often seem to just ignore or disbelieve patients.
