No metaphor is a perfect fit for the situation. It's a didactic device, nothing more.

Nevertheless, nobody's getting criminally prosecuted for accidentally fetching a file. Even someone who accidentally downloads child pornography once is unlikely to get in trouble for the mere act itself, provided they delete it as soon as they receive it.

Acts that are getting people in trouble are intentionally downloading files they have no good reason to access, clearly aren't authorized by the owner, and the circumstances surrounding the activity indicate an illicit purpose. All the facts that indicate guilt are going to be argued by an AUSA to a court and possibly a jury; no judge is going to hang someone (metaphorically speaking) for a mere accident.

There's a good twilight zone episode where some alien kids come to earth to go camping. They get discovered, hunted to their death by humans and in their last move they activate a distress beacon. The closing shot is a alien craft dwarfing earth.

I would love this so much, but uploading the IPA would be a bit of an issue :/ it would be impossible at my previous company (a large supermarket) and now I’d have to get justification. It would be good to get a little bit more info on how it works or rather have the results of a demo app that can be accessed :)
Ask HN: Bad idea to switch to TPM role if I still enjoy dev work?
I have an offer on the table for a TPM role, company who's tech / industry I have direct knowledge of. For instance I've forked their open source code, provided features people like etc etc.

I have 3.6YOE as a backend dev, no existing PM experience other than a role at a previous growth stage company I worked for. Long story short, I really want to work for them but their offer was low ($120k w/ benefits), more than 15% less than what I currently make at a no-name startup.

I suck at leetcode, but at this point I'm weighing my options as to whether I should stick it out for a few months (grinding leet) and chase far better money as a dev or spend a year at this new TPM gig, take a bit of a $$ hit to speed up the transition / career hack of not needing to switch to PM work internally and later take the PM track at FAANG and largely have a better chance at high TC than I would as an engineer?

I'm mostly worried about how difficult it would be to get back into dev work, if I either dislike PM work or realize I have better TC potential as an engineer.

That is because there is not realistic replacement at this stage. They are being developed and will get there but we are not there yet, not with out causing not just a "reduction in living standard" but more like famine, disease and death

How much poverty, death are you willing to accept, because during COVID that answer was ZERO, so i am wondering what the answer is here?
> Missing something?

From what I've seen on OSINT Twitter, I think what you're missing is that Russia is not actually all that good at cyberwarfare in terms of hacking high security systems, or even securing their own systems. There was a story today about a high ranking general who was killed and it was picked up by the OSINT community due to Russians using unencrypted phones to communicate on the battlefield. Extremely rookie mistake. Russia's cyberwarfare strengths seem to end with simple DDoS attacks and propaganda bot nets on social networks.

> Another change in topic: bubbles. I’ve written before about how 46% of Americans are young-earth creationists, and how strongly that fails to square with my personal experience. I’ve met young-earth creationists once or twice. But of my hundred closest friends/co-workers/acquaintances, I think zero percent of them fall in that category. I’m not intentionally selecting friends on the basis of politics, religion, or anything else. It just seems to have happened. Something about my personality, location, social class, et cetera has completely isolated me from one particular half of the US population; I’m living in a non-creationist bubble in the midst of a half-creationist country.

Equating SATs with IQ is a bad (and incorrect) conflation.

An SAT is (ostensibly) a measure of learned skills.

I'm originally from NZ so have never done SAT, and I was in the last year that had what were called "University Bursary" exams which serve the same university entrance purpose. The exams seem much more complicated than SATs but then NZ has far fewer people so manual grading is achievable.

My experience with standardized testing is through my partner, and what I learned while they were preparing for MCAT and the general postgrad one (acronym???) was: Achieving a high grade in the US standardized testing system seems to benefit hugely from tutoring/training on the actual tasks of taking the tests, including a wide variety of "tricks" that serve no practical purpose outside of the testing system. There is immense time pressure, far more than I believe that there should be (and again private training helps with that as well).

Because that training costs money it has the functional effect of creating a system the has a bias in favor of people who can afford it. Given having money already provides considerable benefits do educational proficiency (through many factors), this just reinforces that.

So I can understand why there is concern about bias, but I think dropping SAT, etc entirely is far too extreme a response.

An IQ test is (again, ostensibly) a test of innate intelligence.

IQ testing as a concept has been fairly comprehensively debunked numerous times at this point due to a variety of effects that impact test results (availability of reading material while young, nutrition, cultural background, and so...). Starting from an assumption that IQ is real, then a test that accurately measures IQ should not vary in such a way, if it does, then the test isn't measuring IQ. That's where the IQ concept gets into trouble: no one has been able to develop a test that isn't influenced by factors that are not "innate".
Certainly a unique experiment, however behind the scenes things were let down by poor experimental procedures, minimal experiment designs, outrageously inaccurate data analysis, and poor recording equipment.

> the FMV and strike price are equivalent at time of grant (now) [therefore] there is not yet any inherent "value" to these options.

i think the implication here may not be correct: one component of the value of options comes from max(market price - strike price, 0), a second component comes from time value -- i.e. the expected value of the option before it expires. since there is some probability that in future the market price of the stock will exceed the strike price before the options expire, there is some strictly nonzero time value component.

i cannot comment on the tax situation. the time value component clearly has some positive value to a speculator.
What? What is your answer? I assume by capitalism you mean economic prosperity. Climate change is going to be terrible for economic prosperity. On the other hand, there are a lot of jobs to be had addressing climate change. The problem isn't that we have to choose between economic prosperity and doing something about the climate, but that certain vested interests will be harmed. If you've invested billions in prospecting for fossil fuels and buying up mineral rights your ox is going to be gored. These people, who only foresee a few more decades of life before them anyway, have a lot of spare cash to invest in propaganda to change the subject, confuse issues, and divide the electorate. Telling people that they have to choose between the economy and the climate is one of the ways they do this. Don't buy it.

You're quoting

> “Some people call it a crisis. That has a pessimistic vibe associated to it and I don’t feel that way about it,” said Garcia Garcia. “It’s a time where I feel like we are on to something profound.”

They are using past experience of a crisis (say from late 19-century) to infer what comes next is a major paradigm shift. This might very well be true, but we didn't know that. We should be optimistic about our career and the future of physics, true. But we should not be in denial that this is a crisis. There's absolutely no information (but hints) we have right now that tells you a breakthrough is coming. The next paradigm shift may happen in arbitrary far future, or may not happened at all if it is out of the reach of humanity.

Also, people don't call it crisis just because we hit a wall. But we're hitting a half century wall now (since 1970s.)

Gravity is also theory - but there is so much evidence that a layman would call both a fact.

The drafting is not the best. The key point is that objects have bounds (even though it doesn't explicitly say it), and pointers point to a base object, and it's UB if those pointers go outside the bounds of that object.

malloc is defined to return a pointer to a new "base object". But your code doesn't do that; you can see by reading it that it returns a pointer to `data_storage`. That means the UB conditions for using that pointer don't match the spec.

You could say it's supposed to magically work if the function is named `malloc`, but my understanding of all C implementations is they don't do that.

I'm wondering if the energy loss through the tensioning and/or internal gears is at all significant.

Instead, would it make sense to have a heavy flywheel, a fixie gear, and a way to slowly ramp up the power draw, so the power draw itself is the "gear" that allows you to go from a hard-to-start heavy wheel to a smoothly-running wheel?
This is it for me as well. The best way I can describe it is "bloat."
Maybe they were correct, and a non-Trump canidate would have won by a larger margin.
In the 1990's this was an extremely common view, at least in the U.S. Teachers, parents, politicians, and practically anyone else in a position of authority all routinely told us that sending all the manufacturing to the east was going to enable us all to become designers, lawyers, writers, etc. This was "The Future", and everyone in America was going to go to college and become a knowledge worker.

Any time someone would raise concerns about potential negative impacts, they would either be told that they were living in the past, or that the answer was education. This was a staple of the economic and domestic policy of both the Clinton and G.W. Bush administrations.

It seems laughable now, but man, at the time, most of us bought that crap hook, line and sinker.
Scratch and especially Python are a lot more complex than BASIC. OTOH, Scratch having a structural rather than solely text-based interface might also make a more complex language immediately usable, by removing the difficulty associated with keywords and surface syntax. This is the kind of thing that would really benefit from a well-designed usability experiment.

>someone says that BTRFS is more likely to become corrupt with power failures

No. If the drive honors flush/FUA, Btrfs is less likely to corrupt data or metadata than overwriting file systems because the interruption won't result in incomplete overwrites. So this would hold true for any copy-on-write vs overwriting file system (and probably also log based file systems). The trouble is if the drive is transiently lying about flush/FUA success, and then there's an ill timed crash. There's the chance the super blocks written point to trees that don't exist yet because the write order hasn't been honored due to flush/FUA being ignored. There are backup trees, so it might be possible to work around this defect with the `rescue=usebackuproot` mount option, but sometimes the defect is so bad that you get all kinds of write reordering such that Btrfs only finds trees with the wrong generation, and it fails to mount. Often it's still possible to get your data out with the offline scrape tool, `btrfs restore`. But it's a difficult problem to deal with. In theory it's similar on ZFS but I know nothing about its on-disk format so maybe its metadata has some locality in which case certain assumptions could be made to allow it to better work around such a drive firmware defect? I'm not sure. On a power fail, it is possible Btrfs loses the most recently written data if the writes that were in-progress and thus not yet fully committed to stable media. How much data really depends on the application doing the writes.

>In case of a disk with damaged sectors

Btrfs by default keeps two copies of metadata and it automatically deals with this problem, while also self-healing when such problems are encountered.

>a filesystem with a simpler structure will lead to an higher probability of recovering the data, while I think that with BTRFS, or any filesystem that is COW, uses compression, volumes, etc that is more difficult, because files are not stored as plain blocks on the disk, but have a more complex structure that must need to be decoded.

The ondisk format is fairly simple and extendible. Metadata isn't subject to compression. In the case of bad sectors with compressed (user) data, you'll certainly lose more data than if it weren't compressed. There's an expected trade off here, it's not really a Btrfs issue but just the way all compression algorithms work. You get some small corruption and it'll have a bigger effect.

>So for the purpose of making backups and archiving data, I think that I will stick with ext4 for a while.

I used to hedge my bets by having multiple copies of data on different file systems (including ZFS) but haven't done that in years. I've seen too many cases of (hardware induced) data corruption being replicated into backups and archives without any warning it was happening until it was too late - and only corrupt copies remained.
Not the OP, but I deployed btrfs on tens of embedded systems that had their power consistently cut on a daily basis. Ended up with unmountable filesystems repeatedly. Switched to ext4 and never had an unmountable filesystem again.

These were single disk systems, no raid at all.
