Please find one web server being actively developed using one process per request.

Handling thousands of concurrent requests is table stakes for a simple web server. Handling thousands of concurrent processes is beyond most OSs. The context switching overhead alone would consume much of the CPU of the system. Even hundreds of processes will mean a good fraction of the CPU being spent solely on context switching - which is a terrible place to be.

> They should have coordinated with Pakistan to run the strikes.

Like when America coordinated with Pakistan to grab Osama? Actually no, they didn't coordinate with Pakistan because the terrorist was being harboured by the Pakistani military. Coordinating would have had the same effect as tipping the terrorist off and letting him escape.

Your comment assumes that Pakistan doesn't view harbouring and training terrorists as a legitimate way to conduct their foreign policy.

> I find this sentiment increasingly worrisome.

I don't know this sentiment would be considered worrisome. The situation itself seems more worrisome. If people do end up being beaten on code design next year, there's not much that could be done anyways. If LLMs reach such capability, the automation tools will be developed and if effective, they'll be deployed en masse.

If the situation you've described comes, pondering the miraculousness of the new world brought by AI would be a pretty fruitless endeavor for the average developer (besides startup founders perhaps). It would be much better to focus on achieving job security and accumulating savings for any layoff.

Quite frankly, I have a feeling that deglobalisation, disrupted supply chains, climate change, aging demographics, global conflict, mass migration, etc. will leave a much larger print on this new world than any advance in AI will.

I finally got it after a good few hundred tries, iirc. Prep for having the patience to finish Final Fantasy XV's Pitioss dungeon.

My boyfriend at the time (who'd bought VVVVVV for me), on the other hand, was attempting a no-death-all-trinket run. I could never understand just how damn good he was at gaming.

Oh, and PPPPPP (the soundtrack) remains a staple. Especially the associated osu! Stream tracks.

Like anyone new to a leadership role, it seems the director is conducting a kind of audit to both assess the current situation and establish their own footing — even though this is fundamentally a human/relationship-based process.

From what you've described, there are a couple of likely possibilities:

First, the director may still be gathering information to form an informed opinion about the team's capabilities.

Alternatively, they might have already formed an initial impression and are now seeking confirmation through these interviews and interactions.

In either case, I don't think there's anything here that should make you feel discouraged or take it personally. I completely understand that it can weigh on your mind — it's a common and often uncomfortable experience in the workplace. But it's not unusual, and it doesn't necessarily reflect poorly on you or your team's work.

I have worked on this professionally; it's quite hard. Even getting exploits off of non-honeypot devices is hard. Setting up a honeypot adds even more complexity, especially because of how much fingerprinting attackers do. Before sending the initial payload it's likely that your phone OS, hardware model is already known–they're critical to deploying the exploit. Rough geographical location, who you've been around, which one of your devices is being targeted–all of these are not that hard to get. Once you're on the device and have elevated privileges you can run even more checks!

> there was never a separate country called "Ukraine" before 1991

By your standards there was no separate country called Russia between 1918 and 1991. So how is this different?

Also absurd argument. There was no country called Belgium until the 1830s. So what?

> So this distortion of reality works the other way round

So your justification for distorting reality is that other people are allegedly doing that so it’s fine for you to engage in that as well?

It's purely anecdotal but does have some provenance going back at least to the 19th century, with one of the early liver specialists.

He was reportedly at a cocktail party one evening when a messenger burst in and informed the esteemed doctor that one of his patients appeared to be dying from a heart attack.

"My good man," he replied, "that can't possibly be true. When I treat a patient for liver disease he dies of liver disease."

I don't see anything about relative humidity (RH).

While temperature is important, if you have a well-seal and well-insulated house (i.e., up to modern code), your AC won't be running that much, and so the incidental dehumidification you get with it won't happen, which will lead to an RH that creeps up.

A stand-alone whole house dehumidifier is thus often needed to deal with RH.

It's not latin-1, and it's not ASCII either. It's 7-bit GSM 03.38 charset, with optional shift tables. You can use either that or UCS-2 (though these days phones use UTF-16 instead), and UCS-2/UTF-16 significantly limits the number of characters that fit into the message (160 vs. 70).

>Not caused by, but the economy didn’t fully recover until all the wartime production started, and the measures that had been put in place to curb unemployment had been short term solutions with only a limited effect

Are you seriously arguing that we need military commitments so we can hope that war breaks out right around the time of an economic depression?

It seems to me that you've basically conceded the point that the US doesn't benefit from its involvement in Europe, and its involvement is simply out of misplaced idealism. I'm just saying, we should stop doing the idealism.

We both agree that the idealism is misplaced and America is a nation of fools. All I'm saying is you should accept the logical consequence of your position, and agree with me that us fools should stop wrecking everything in the name of "freedom and democracy" nonsense.

>You see the problem with you people is that you’ve strong armed your way into everyone’s business for the past century, trying to change cultures and ways of life, far beyond simple alliances - only to now turn around and abandon your so-called allies as soon as they become inconvenient for you. I say this as an African living in Europe who experienced firsthand one of your regime changes and subsequent cutting of ties when the new regime didn’t align

Europeans mostly complain about our influence on the continent, despite 80 years of peace and prosperity post-WW2. If that's not enough to please them, nothing ever will be.

But in any case: We are very bad at foreign policy and we should do less of it. That's my position. We aren't going to get any better.

The post-WW2 experiment, initiated by Dwight Eisenhower, to have a more interventionist foreign policy, has been a failure, and at this point everyone agrees on this. Most of all, it has been a failure for the USA -- our relative GDP has fallen, meaning the rest of the world got rich quicker than we did. (This demonstrates how we have been manipulating the global economic system for our own benefit, naturally.)

As a voter, I don't have the capability or wisdom necessary to reform the US foreign policy establishment. Best I can do is to hope for less foreign policy.

Everything is always America's fault, as you yourself say. No other countries have agency or responsibility. For example, America is the only country that ever seeks to influence others.

America is the only country which seeks to ally with leaders that are aligned with it. Other countries don't care whether their partners are on the same page or not. This is a uniquely American trait. Other countries just choose who to ally with based on whether they like the design of another nation's flag.

Regardless of how things go with e.g. Ukraine, America will always to blame. We will be to blame no matter what we do. So we might as well focus on helping ourselves, and mind our own business.

Years ago I suddenly had a swollen knee. So painful that I barely can walk. I dragged myself to Kaiser thinking that I torn something in my knee. Later on, it was diagnosed as arthritis

Doctor said it was incurable, and gave me a list of meds where the side effects looked worse than the disease.

I rejected it, and started examining every piece of data known to mankind.

This led to me to variety of things. First was biological, a new tech drug that’s super expensive and I had to be on it for life. I was only 30, and no way I’m taking a drug for life at this age. What if I get laid off (or go travel) and can’t afford the 5k price tag per dose for my entire life?

I then found other treatments, ones more natural but scorned on by the medical elite professionals. I went to Eastern Europe to do oxygen therapy.

I came back home, and was well. I told the clinic that I’m healed now and don’t need to come back for the biologic anymore. The staff at the clinic were appalled — they never heard of a case of someone getting healed and weaning off their meds

The medical system is here to squeeze everything from you. You are the top of the line revenue stream. Your health and wellbeing is in direct conflict of their objective function — make more money

Never forget this

TIL:

> OpenTherm (OT) is a standard communications protocol used in central heating systems for the communication between central heating appliances and a thermostatic controllers.[1] As a standard, OpenTherm is independent of any single manufacturer. A controller from one manufacturer can in principle be used to control a boiler from another. However, OpenTherm controllers and boilers do not always work properly together. The OpenTherm standard comprises a number of optional features and some devices may include manufacturer-specific features. The presence or absence of such features may impair compatibility with other OpenTherm devices.

IMO a lot of the product managers inserting themselves and being useless is good old school project managers pivoting to the new thing and doing the same old stuff. Likewise I do think product management should be part of the senior engineers skillset. Its incredibly useful. Conversely, there are also tons of engineers that dont have this mindset and want a PM to tell them what to do and a barrier from the rest of the organization... which boggles my mind to be fair

Satellite imagery doesn't go to (or is paid by via some crowdsourcing) public. Maybe 90% of the videos ie on r/CombatFootage are from drones, maybe even basic DJI ones but operated by military.

Its a voluntary decision of those in command to share these, from both sides, nothing less and nothing more, to continuous amazement of both civilian and military communities watching those (some stuff I saw I'd never say is possible or would happen, no need to go to details some of it is beyond brutal).

You are maybe mixing Syria war footage - there are tons of them from around 2016, done as you say via phones or maybe some cheap gopros or consumer cameras of that time. That's not a typical Ukraine war footage.

The lecturer did suggest the following supplementary material:

- Glynn Winskel. The Formal Semantics of Programming Languages: An Introduction, MIT Press 1993. (Mainly chapters 1, 2, 3, 6, 11)

And many things didn't come to pass. The entire business between Israel and Iran from last year springs to mind (also recall that many feared the Bush administration would seek war with Iran, which never happened). The Cuban missile crisis was resolved, and there was no nuclear war in general during the Cold War. etc. etc.

In the end this is just information-free hand-waving which says nothing about the current situation.

The alternative is duck-typing, hard-coding a method name, like Python’s __dunder__ methods. That’s just as strange. And for Rust, definitely unacceptable.

I think C++’s range-based for loops work this way, basically hard-coding .begin() and .end(). Oh, and only working on array-like things due to hard-coding ++ as the operator to go to the next item, so it’s less powerful than Rust.

It’s not a stable part of Rust, but you can provide your own definitions of lang items, not using even libcore. But they will need to be quite similar to the official one as the compiler will pretty much hard-code aspects of its definition.

An alternative view of it is that the standard library is reaching into the compiler. This feels just as accurate as the other way round. The two can’t reasonably be separated. A good fraction of Rust’s standard library is stuff that needs to be there, couldn’t be anywhere else.

My guess is that it doesn’t work for several reasons.

While we have millions of LOCs to train models on, we don’t have that for ASTs. Also, except for LISP and some macro supporting languages, the AST is not usually stable at all (it’s an internal implementation detail). It’s also way too sparse because you need a pile of tokens for even simple operations. The Scala AST for 1 + 2 for example probably looks like this,

Apply(Select(scala, Select(math, Select(Int, Select(+)))), New(Literal(1)), Seq(This, New(Literal(2))) etc etc

which is way more tokens than 1 + 2. You could possibly use a token per AST operation but then you can’t train on human language anymore and you need a new LLM per PL, and you can’t solve problem X in language Y based on a solution from language Z.

We never will see such changes for anything as far out as the hypothetical planet nine. The orbital periods for objects beyond 100AU are measured in thousands of years, as far as our observations go they might as well be stationary.

Yes, unusual values for orbital parameters are only evidence that something happened in the past, but that thing that happened in the past might have been "close approach with a planet". And as a hypothesis, this is in no way less valid or likely than a flyby with a star.

Not my experience in London. In any zone that is not Zone 1-2, or other Deliveroo hot spots, my experience has always been not great with times that do reach also the 45 minutes to 1h for food delivery. We still do it occasionally _because we are lazy_.

However, we did draw some lines as some foods are not enjoyable in case one of those long wait times happens (e.g. pizza, burger, cooked meat dishes, etc).

> I grew up with all the classic 8 bit micros

Meaning that all the machines I've ever cared about have had 8 bit bytes. The TI-99/4A, TRS-80, Commodore 64 and 128, Tandy 1000 8088, Apple ][, Macintosh Classic, etc.

Many were launched in the late 70s. By 1985 we were well into the era of PC compatibles.

Why did GNOME and basically all the large distros all jump with both feet in on using systemd? Because it was better. It was simply significantly better than all the alternatives. For the vast majority it was a no-brainer upgrade. The holdouts were the one's who had simple needs and were already happy with what they had. The rest of the world jumped on systemd. Because it was better.

The pain of Ansible+Jinja2 is what eventually pushed me to write judo[1]... It works surprisingly well for what it was built for, but of course has limitations (e.g. there's no direct support for a templating language; you just plug env variables into a script). The idea is, do less, and allow other tools to fill the gaps.

There's still a lot on my todo list, like env files, controlling parallelism, canaries/batches, etc. I'm currently doing these things using hacky shell scripts, which I don't like, so I'd prefer moving that into the main binary. But I still prefer it as-is over Ansible.

The implicit problem here (pun intended) in the given examples are implicitness vs. explicitness.

Rust chose (intentionally or otherwise) to do the opposite of the many things that C++ does, because C++ does it wrong. And C++ does it wrong because we didn't know any better at the time, and the world, pre-internet, was much less connected. Someone had to do it first (or first-ish).

The main thing I like about Rust is the tooling. C++ is death by a thousand build systems and sanitizers.

If you are actually arguing that a country targeted by a terrorist attack does not gain deterrence with a counterstrike relative to letting things go on, then how uniform do you consider this prescription? Should the terror attacks in the US or France not have had a military response?

What happens to the incentives of terror groups in response to such a policy?

---

The role of money only becomes an issue when conducting a terrorist attack becomes expensive. Missiles and jets consume much more money in comparison to training recruits via an intermediary organization like LeT and sending them across the border to carry out attacks.

A regime in which a terror attack leads to a high pressure, expensive situation for the Pakistani military is completely different from regularly scheduled, train and deploy terror attacks from militants which used to happen earlier.

In that situation, the military has to respond to economic pressure, pressure from allies and pressure from its own people.

> In the very narrow fields where I have a deep understanding, LLM output is mostly garbage > Thus I have to assume that for any topic I do not fully understand - which is the vast majority of human knowledge - it is worse than useless, it is actively misleading.

Why do you have to make that assumption? An expert arborist likely won’t know much about tuning GC parameters for the JVM but that won’t make them “worse than useless” or “actively misleading” when discussing other topics, and especially not when it comes to the stuff that’s relatively tangential to their domain.

I think the difference we have is that I don’t expect the models to be experts in any domain nor do I expect them to always provide factual content; the library can provide factual content—if you know how to use it right.

Simple way to detect if you're in an area with ticks: tape a white washcloth to a long stick and swish it back and forth around the ground. Check the cloth for ticks every so often and you'll find the tick "hotspots" and can avoid them. Permethrin-treated clothing is also fantastic for protecting against ticks - it's just highly toxic to water life and cats in liquid form.

Some of these protections are quite trivial to overcome. The "Frozen song copyright" section has a canned response to the question:

The canned response is returned to this prompt in Claude's reply. But if you just drop in some technical sounding stuff at the start of your request, the model will happily produce some copyright-infringing content for the party.
