Things can stay the same way for a long time, especially since, as you point out, governments now have large scale surveillance/ controls tools.

That doesn’t mean that things will be going well for these populations. You might just have a lot of death and suffering that will be ignored or hidden form the wider population.

You might also have important declines in life expectancy, wellbeing and happiness.

So, sure, a system can be robust and stay in place for a long time, doesn’t mean it won’t suck.

> Perhaps after covid people will take their health more seriously?

I'm not hopeful of it. The problem is that it's just such good business to keep people in poor health. Consider all the products that can be sold to them:

- addictive junk food to exacerbate the cycle

- type 2 diabetes medication

- plus-size clothing

- plus-size identity media

- weight loss programs and medications

Now, I'm not saying that all of this is done intentionally. But what I am saying is that strong incentives exist to keep selling these products and keep demand for them high, unless society as a whole agrees that it's wrong to do so, (as it eventually did with tobacco) at least without warning.
A lot of that sort of thing is abstracted away by common standard libraries. I don't tend to run into a whole lot of XOR on a day-to-day basis, apart from when digging into low-level libraries.

>"Why do you trust AWS when Amazon kills failed non-AWS products left and right? I even remember Bezos bragging about this being a core part of the company culture."

I'd be really interested in this quote and its context. At AWS, things are always iterated upon and tested. But there's an incredible emphasis on two-way door decisions. Basically, don't make big decisions that can't be reversed if things go poorly. And once you've released something customer-facing (especially something as important as a new AWS service), you're locked in for the foreseeable future.

There are still CloudHSM v1 HSMs running out there in the wild. CloudHSM v2 was released in 2017. And CloudHSM v1 hasn't been available since at least 2019.

When I use a local SIM, it goes into an old phone and my regular phone stays like it is. (I don't actually do a lot of texting anyway. The data is mostly for things like maps and directions.)
GPT-3 is trained on text prediction, and there's been a lot of commentary about the generation aspect, but some of the applications that excite me most are not necessarily about the generation of text, instead, GPT-3 (and also other language models) create very useful vector representations of natural language as a side effect that can then be used for other tasks with much less data, or with too much extra data. Using the text prediction task as a way to supervise learning this representation without having to create an expensive labelled dataset is very helpful, and not just to language tasks. See for example the CLIP work that came out recently for image classification, using GPT-3 and captions to supervise training. There is other work referred to in that blog post that also exploits captions or descriptions in natural language to help understand images better. More speculatively, being able to use natural language to supervise or give feedback to automated systems that have little to do with NLP seems very very useful.

Why React Context Is Not “State Management”(and Why It Doesn't Replace Redux)
IIRC immediate operands have to be the same size as the destination, so to zero a 32-bit register you need a 32-bit constant, and it simply makes the whole instruction larger than a simple xor.
Premise: A is containing all values in range [1, 4] except one:

Let's say that, without loss of generality:

However, A is now missing no value. Contradiction.

At those speeds, everything is "flexible" in the sense that even metal just flows in a fluid-like manner (see picture linked in the comment).

Also, the material would have to somehow convert the energy of an entire car crashing into it at full speed. Except the car is only an inch wide.

Not necessarily true for most architectures. Many RISC architectures have a "zero" register, so a canonical "move short immediate" instruction could be "OR Rn, R0, #n" ("OR R0 which is always zero with n and store into Rn") or the same with ADD. Then clearing Rn will usually be "OR Rn, R0, R0", "ADD Rn, R0, #0" or something like that.

If you need XOR of two boolean values, you can just "z = x != y". That's my favorite XOR trick, as it's easily understandable and readable.
The point of the vaccine is to end the pandemic. An early benefit of the vaccine is reduced load on the health system.
Careful abusing these tricks. Over 10 years ago I decided to implement an RC4 (arcfour) cypher to generate pseudorandom noise for a test program.

The algorithm looks like (from wikipedia):

i := 0
j := 0
while GeneratingOutput:
i := (i + 1) mod 256
j := (j + S[i]) mod 256
swap values of S[i] and S[j]
K := S[(S[i] + S[j]) mod 256]
output K
endwhile

Being a smartass 1337 coder (and declaring intermediate variables always being a bit of a bother in C89) in my implementation I decided to implement the swap using the xor trick:

s[i] ^= s[j];
s[j] ^= s[i];
s[i] ^= s[j];

I then ran a few basic test vectors, everything seems to work fine.

A little while later I noticed that the output of the cypher was weird, the longer it ran the more zeroes I would get, eventually getting only zeroes.

The keen reader will already have spotted the problem: whenever i and j happen to be equal instead of doing nothing the code sets the entry to 0 (since x ^ x == 0 for any x).

And that's the story of how I never used this trick ever again.

In general it's always better to write clear, concise code and let the compiler optimize it. If it turns that the code is performance critical and the compiler doesn't do a good enough job then you can see if the smart solution is worth it.

And if you fail an interview because the interviewer expected you to know how to find a duplicate in an integer list by using xor then you probably dodged a bullet anyway. What a silly trivia question.

Yes, you’re right. At least partially recipes call for items in state because prep time will vary significantly by skill level. More cynically, with blogger recipes there is also a potential for SEO games.

Excited about this. I love certain things because they simply last forever and do what they are supposed to. For example about 18 years ago I bought 2 HP12c calculators when I started working in finance (One for work, one for home). Not only have they not broken, but I can't tell you the battery life because they are both still on their original batteries. Now old hands tell me the new modern 12cs (like mine) aren't a patch on the original and the old ones from the 80s had even better battery life than that.

A trash bowl is a really under-recommended thing to have where you're working. A tidy space is much easier to work in, so having somewhere to quickly put the offcuts and mess is a really simple thing, but makes for a way better cooking space.

It's not really about static vs. dynamic linking IMO. The point with ld is that the distribution has one central point for linking. If static linking with go, rust, C, etc. would work in a similar fashion, each executable could be shipped with a "re-link" script and the distribution could again provide security patches efficiently.

But when linking happens in some poorly maintained script, inside a custom build systen, written in two or more languages, running inside a docker container, executed by some year-old CI integration, patching security issues becomes impossible.

I wouldn't say "nobody" wants to see the XOR-trick solution.

Its just that those who DO care about it is asking about the general solution: Reed-Solomon codes, or maybe a more modern (harder to understand) variant: like LDPC or Tornado codes.

Anyone who needs to recover *ONE* symbol from a data-stream with noise actually needs to recover two, three... four... symbols in the general case.

One symbol of erasure recovery is the weakest-of-the-weakest of error correction codes. Its even weaker than the single-error-correction / double-error detection Hamming Code (discovered back in 1950s).

XOR-trick is your "basic parity bit", and is the stuff taught to undergrads to wet your appetite for error correction codes (well... erasure correction in this case. Since XOR isn't strong enough to actually correct an error. Only an erasure).
You're right, I misspoke (mistyped?). Fixed :)

David Graeber's BB Jobs is the second most important book I've read this last year. Truly ejected me out of my worldview.

https://en.wikipedia.org/wiki/Bullshit_Jobs

Previously, a HN commentator shared the distinction between "doing" and "justifying" work (IIRC). I really like this framing, dichotomy. And would like to synthesize with Graeber's thesis.

Another interesting contemporary view is Scott Adams' "confusopoly". I have a few other issues with Adams; I wouldn't be able to get out of bed every day if I shared his bleak view of humanity. But I can't deny that he does have some very penetrating insights

BS Jobs and confusopoly are complimentary. Young idealistic me always equated capitalism with producing stuff efficiently for profit, and the sharing of that surplus. The kids today use terms like "late stage capitalism". Graeber examines financialization leading to managerialism, aka rent seeking. My rephrasing is the point is to maximize inefficiency to better transfer wealth to the management.

Apologies for this stream of conscious ideation. I'm still chewing on these concepts, insights.

Meanwhile, I sympathize with your situation and hope things improve, for everyone.

I'm not sure the package problem is really a problem for beginners. Just within the last year firsthand I've seen people in undergraduate classes, in graduate classes, and at work try Python the first time, and the default install of Anaconda worked for them in every case. The classes were taught by different professors, and they all suggested Anaconda independently and were not Python programmers.

It is overkill/brute force to install all the Anaconda default packages when a beginner is not going to use over maybe 5-10 libraries, but it's a solution that has worked flawlessly for beginners from my experience watching non-software engineers and "non-technical" people using Linux, Windows, and MacOS try Python for the first time in math and data science classes.
But you imply those mitigations must be made to correct the "natural," initial orbital state, when in reality, the orbits were never truly circular or co-spherical.

You don't have to meal prep per se, but I find having a plan helps. Buying and preparing food when you're hungry will make you eat more of the wrong stuff than if you had a plan.

I also found that by basically tripling my intake of vegetables helps a lot with feeling satiated. No one ever got fat because they ate too much broccoli, lettuce, and spinach.
It's larger, because it needs to fit a 32bit value of 0 in the instruction, and thus e.g. on x86 needs 5 bytes, whereas xor reg,reg needs 2. As such it was a common code size optimization, which in turn has lead to CPU manufacturers optimizing their CPUs to recognize it and treat it even more efficiently.
Disagree on the last sentence.

You simply can not compare the amount of work that will be required (collectively and individually) in either outcome. Improvements to Matrix are being made, and both Element and the Matrix foundation are supportive of further developments and getting more people onboard.

Don’t underestimate how unruly, disobedient, and oftentimes violent these children are.

In the best case, these children have been traumatized by their removal from a family, however dysfunctional. In the worst cases, they’ve suffered abuses that make people support the death penalty. While none of those scars is written on a person, they do manifest in sudden outbursts of screaming, hitting, stealing, and scores more destructive behaviors. For a neglected child, negative attention is preferable to not existing, and if acting out is the only way to make your existence register to the outside world, so be it.

Many of those people who placed said children in shackles aren’t practiced in methods to manage traumatized children or understanding of their past, and identify them as ‘problematic’, not ‘traumatized’.
It's not overhead, it's about dependency breaking. 32-bit xors on a single register are universally recognized as a zeroing idiom, which means the CPU doesn't have to wait for the results of previous operations in order to set the value of the applicable register to zero.

In modern CPUs zero'ing idioms aren't even executed, they only get as far as the register allocater. The register allocater will allocate a zero'd physical register for the architectural register that had the idiom applied to it and the job is done.
One can't plan for anything; it's a player versus player game that requires constant responses to what the opponent is doing.

It's about as far-fetched as saying that one can plan a boxing match.

There is certainly less possibility of planning than cooking.

Admittedly it may be more accurate in this case to say "temporarily inconveniencing millions of people", but it must feel quite oppressive to find that the only sub-reddit you use has been blocked, then the only YouTube channel you comment on gets banned, then the only social media app you use gets shut down.

Eventually some of the people affected would just give up on trying to communicate with like-minded people online altogether, which I suppose is the point. Remember, though, we are talking about First Amendment protected speech for most of these people.

You may say that no one needs to be able to communicate online, and as long as someone can use the postal service then they haven't been silenced, but by that logic you could say that a regime which locks up its political opponents hasn't really "silenced" them as long as they are still allowed to write letters.

> pleasant person, are a team player, whether they have leadership aspirations, and take responsibility.

I know the above is a popular opinion, but I've worked as a SWE at a company A that had a "technical interview" process and Company B that didn't have a formalized one.

I would much, much prefer to work at company A (pay differences aside) because of the type of person who passes these interviews. It can be quite difficult to determine someone's capability at interview-time. But company B had lots of competency "false positives" (in my view) whereas company A had very few. That's the value of a technical interview.

That said, of course the XOR solution would never be the only one accepted, but it would probably get you brownie points here.
That would seem reasonable if you consider Russell, for example, as a philosopher who knew mathematics.

But it seems equally valid to consider him a mathematician who knew philosophy. In which case, you could just as well frame the argument as mathematicians and scientists no longer have a good understanding of philosophy and are therefore incapable of contributing to the philosophy of their field.
