> you are expected to know your algorithms cold and be expected to field your domain specific questions

...why?

You're holding candidates to high standards, fine, that's great. Compiler designers even need some deep algorithms and datastructures knowledge; you can't ensure your hashes are thread-safe unless you know exactly what they are, how they handle collisions, and so on. All that's totally fair to ask as part of their domain knowledge.

But the criticism of this sort of interviewing (and Google in particular) overwhelmingly describes interviewers judging domain experts on whatever algorithms puzzle they give every candidate from every domain. Why do we care whether a compiler design expert remembers how to implement Ford–Fulkerson on a whiteboard? Is there any reason to think that's predictive of talent? Might it even be anti-predictive because it favors generalists?

Google (and FAANG, and everyone else in that league) hires great people. I don't doubt that. But it was also hiring great people back when it posed random brainteasers and emphasized GPA, and Google has publicly said those things turned out to be totally uninformative. If you filter down to a list with more highly-qualified candidates than you can hire, I think there's a tendency to come up with random extra hurdles to avoid resorting to a coinflip that might work just as well.
As to your last point, pastures could be used to plant forestry, which locks up carbon in timber.

What an unnuanced and dare I say prejudiced comment. Whatever happened to liberals? We used to be the open-minded ones.

Even if you're just coming at it from a place of power politics.. you think MORE packing of liberals into fewer and fewer areas is going to swing it for us? If tech companies were serious about liberal politics, they'd be opening big offices in TX and OH. Could solidify the blue wall for a generation with a few 10k people.
I worked on almost the exact same idea for my senior design and the audio output from the dac built into the pi is terrible. The HiFiBerry board was a life saver.
You're saying it's okay to bully people and violate people's privacy because it's good for them? Interesting argument.

If you really believe that argument, post the most cringeworthy video of yourself on the Internet. For the cred.

You're right that the way these things get found usually isn't by Googling. If something's on the front page of reddit, the most likely way is your friends or colleagues will run into it and pass it around. In smaller communities, that may continue for years.

But Google is certainly a way people will find it too, even if the name isn't in the post. Search engine 101: the way Google works is by looking at text in incoming links. If I have a few links posted on social media which say "Hey, chmod775 lost his temper in a restaurant and boy did he make a fool of himself," that's exactly what Google will point to. If this person isn't famous enough to have other high-profile pages about them, it's likely to be on page 1, or even the top link.

I've been doing a TON of work around PDF lately with my Polar project and wanted get feedback from you guys:

https://getpolarized.io/

I just implemented bulk PDF import this weekend.

It uses pdf.js for the rendering of the PDFs and extracting the metadata (including the fields discussed in this article)..

I have to manage a ton of PDFs for my work / research. Mostly textbooks and compsci whitepapers) and and before working on Polar I was really struggling to manage all the data.
"Although surely not serious ..."

Not your parent but I took it seriously and I think "skin in the game" structures like this should be taken very seriously - they are likely the best mechanisms for aligning interests.

"This assumes everyone values personal health over financial health."

Very easy to solve this one - the elected official doesn't eat the fish and drink the water, their children do.

"This prevents anyone from wanting to get elected to fix an existing problem."

This is a good and important point - you would scare away potential candidates for office if existing systems are already broken/unsafe. I don't know how to arrange a neat solution to this.
Blockchain: Banking the unbanked
We live in a world where Cobol mainframes are still around and in use. Microsoft can not depreciate ten year old technologies when the vast majority of their clientele in this sector are enterprises.
Its got a very high perch to cool down from. There's definitely a seasonal element to the current slowdown - price drops are happening, but prices are still up 5% YOY. I'm hoping for a correction or at least 0% for a little bit.
That's another good example. Tax that, and you create an incentive to either eat "dumber" meat like fish instead of pigs, or meat where you've avoided the "sin" altogether. Such as lab-grown meat.
I agree with some of your other points... however

> Texas is also building high-speed rail, which will end up linking all of their major cities, an immense bonus.

Denver already has light rail connecting the airport, Boulder, and Golden as well as other metro areas, as well as amtrak, shuttles, and other public transport to the mountain regions for skiing and other recreation. It's also among the most bike-friendly cities I've seen in the US, with routes extending extremely far and having a vibrant cycling culture. Workers commute with all of these options every day.

For being a smaller metro, Denver-Boulder's tech scene is much more vibrant than DFW's. Amazon _already_ has tech offices in both Boulder and Denver.

Among Texas cities, Dallas also doesn't have the tech talent pool and established network of transplanted tech companies that Austin already has, let alone the politics that many west coast tech workers (and Bezos) find attractive (although that point is kind of moot, because either way it's still Texas).

I don't really think it's going to be Denver, either. I'd be really disappointed if it's Dallas. I expect Chicago, Boston, DC, or Atlanta.

Selling drugs is pretty deep, try it sometime. You really feel every dollar. Now I’m more connected to money and survival. Great capitalism experience 10/10.
Can't speak for the other cities but there's been a steady expansion of Amazon in Toronto.

I suspect in the end they'll keep expanding in a quiet and steady pace while never officially declaring a "HQ2" at all whilst the cities feud over who gets the title and keep handing out incentives.

How about manipulating front page content to harass an unsuspecting user, juxtaposing public info such as an affiliation that’s documented on Wikipedia with content intended to gaslight the victim?

Earlier, popular content had links to endless malware.

Reddit always has been a cesspool. It’s simply symptomatic of a much broader societal cancer. I’m confident we will root out such problems in time, though.
You might be on to something.

My main concern would be "what happens when something goes wrong". Either a DOS attack (e.g. crashing the cell network), someone(s) finding that their vote was flipped, or someone(s) falsely claiming that their vote was flipped.

I suppose short term DOS can be handled by extending the voting period in response, long term can be handled by switching back to paper ballots (with the representative system the delay caused by this shouldn't be too much of an issue).

Failed audits are harder to deal with. If you make the system onymous instead of pseudonymous (at least with respect to the voting authorities) you could solve the problem by having a period after electronic voting in which people could cast paper ballots in person that overrode their electronic vote. Large number of failed audits would have to cause invalidating all plausibly affected votes and be considered equivalent to a DOS attack.

Fake votes also become more of an issue. Right now they are basically handled by the fact that the effort/reward isn't worth the risk, but electronic systems make the effort lower (for large scale attacks), reward greater, and risk negligible (for state sponsored attacks launched without stepping foot in the country). Since I already think you would have to make this sort of system onymous, it is likely possible to mitigate this with validation against other datasets... it also has the advantage that any such attacks need to target state hardware instead of phones, that could plausibly be secured.

I think you're size estimate is too small, 300M voters * 10 bytes/voter = 3GB not MB. But it's still a completely manageable size.

The remaining problem with all this is having the government actually implement it in a satisfactory way. Advocating for it would come with the large risk that the government would do something similar, but which didn't solve fundamental security issues. In this respect advocating for paper voting is much safer.
Very pretty, will check back and dig deeper.

I am not a big fan of GUI UI editors because I like building the GUI from models instead. Microsoft had a strong vision in the Visual Basic era that they've carried through for some time.
Or it means constraining your domain and only accepting those programs about which the properties you care about can be proved. Or it means accepting the risk that your system might break.
"There is a recession coming in the near future, which could result in Amazon looking for cheaper developers globally."
It's dangerous to post speculative things with such certainty. The future is never guaranteed.
I don't know if my specific interactions with hypnosis will be of too much insight, but I had been studying hypnosis, taking a few courses on it mainly for the entertainment side of things (making people dance like chickens and such). Then I ran into a course that taught a 10-minute pain relief hypnosis script. [1]

I wasn't sure how effective it would be, but I have intense knee pain every so often at night that won't go away unless I take ibuprofen and wait half an hour. One night I had the knee pain and decided to test the 10 minute script on myself, so I put my headphones on and listened to the teacher recite the script, following along with the visualizations.

Then my knee pain was totally gone. It was a very eerie thing to have this unbearable knee pain disappear entirely without medicine.

Which made me wonder what would happen if I used a similar script and instead of targeting pain, targeted my psoriasis.

I took the original script and rewrote it to focus on my psoriasis, then went to fiver and found a voice-over artist to record the script (so it wouldn't be in my own voice). I stuck my headphones on and began to listen to this script once a day for two weeks.

After the two weeks, my psoriasis cleared up and I haven't struggled with it again since. About 4 years of embarrassing breakouts and flaking skin in public gone in a couple weeks. I had tried topical prescription medicine, pills, all sorts of lotions, scrubs, honey, witch hazel.. you name it, I tried it. Nothing worked until hypnosis for me.

Seconding the other commenter-- I would love for you to elaborate on this.
I've been seeing this same story for what feels like a decade now. Anyone know why this hasn't been implemented yet?
Don't just about all big corporations with some "weight" behind them do this though? A company employing tens of thousands floats the idea that they might leave the city/state due to some new proposed corporate tax legislation or something, and then the city/state exempts them from the increases to get them to stay since they're such a "big employer?" Isn't this just "negotiating from a position of strength?"

This happens in Oregon all of the time with Intel. We don't have a sales tax - we have an income tax and property tax. Everytime we want to raise property taxes, Intel makes a big stink and we give them presents to appease them.

there isn't a shred of evidence

This isn't the place for a discussion about the details of religion, but I guess my response to this is, "So what?"

You may need evidence, but people who believe in God don't need evidence. To them, God exists whether there is evidence or not.

At one time there was no evidence that hydrogen existed, yet is was still there.

At one time there was no evidence that x-rays existed. But they were still there.

At one time there was no evidence of other galaxies or planets. But they still existed.

Something can exist without there being current scientific proof of it. That certain people can see beyond what is physically in front of them is called "faith."
Reverse-osmosis based systems are the current best, cheap and, well, pretty much the only ones available on the market, since it's the cheapest way to purify water. But they have a learning curve, require quite a bit of maintenance and waste some water. Although I believe you can trade wear out of the membrane for less water waste, if water is too expensive in your region. The most basic system costs like $100, has at least five filtering stages with three different cartridge replacement rates and likely needs periodic chlorine disinfection. You can add other stages afterwards: mineralization, UV, etc.
I might be taking words out of context, but 45 million is nowhere near 28% of the US population; this is a little under 15%. I am not arguing for or against the problem of water pollution, but this is just seriously suspect math.
That's not entirely true. If you have multiple implementations, you can compare fuzz results of the implementations against each other rather than against ground truth. There's a project that does this with several popular C compilers that's found some good bugs, but I can't remember the name right now.

This approach does still have limitations, e.g. it assumes errors are independent. And, of course, it requires independent implementations. But it is sometimes more accessible than an oracle.
More people value personal health over financial health than would admit in a survey. They just often don't realize it until they've lost their health.
> we know how bad general code quality is in commercial vendor firmware, it's not surprising to see this

Quite. My experience of firmware is that it's usually total junk, from Internet connected web cams, to HTTP routers, to backplanes for NAS devices.

I was putting together a FreeNAS box for home a couple of months ago and this was the first time I'd seen drives with a self-encrypting ability. I ignored it and went for software encryption.
that will never happen. gmail has over a billion users. we are really the 0.001% who would do something like that.
You can get outraged and mad, and kick and scream all you want.

But it is completely and utterly stupid to "fight for equality". If you want to waste your time and energy, feel free. But people are born differently, some have better bone density, some have a high metabolism, some can build muscle faster. Some people are stronger, faster, smarter, etc. than others.

This makes the world INTERESTING. I am glad there is resistance. I am glad that people need to fight for a better job, or higher pay. How rewarding is it when you finally get that better job, or get the raise. How fucking proud and good do you feel when you claw your way to the top and reap the reward? You want take that away and just hand out the same rewards to everyone? Nah, sounds like a great way to have a dull life and meaningless world.
"What kind of equipment would you need to check your drinking water for any kind of contamination? What would it cost?"

You need to send it away for testing - it would be impractical to home test for all of the things you'd want to test for.

It's likely that your local municipality has a testing service that you can send water into for $50 or $100 and have rough testing done for lead and e-coli and crypto and so on.

A more extensive (and expensive) test will test for essentially everything, including VOCs and chemicals and all manner of manufacturing byproducts, plastics, phthalates, etc.

That would cost you $600 or $800 ...
Migrating from MSSQL to PostgreSQL – What You Should Know
The answer is almost definitely yes, at least in great part. Furthermore, the top two killers in America are heart disease and cancer. 80% of heart disease is preventable by diet - avoiding foods that cause insulin resistance (sugar) and gut dysfunction (chemicals). The top cancer and many others are triggered by environmental variables (chemicals).

And I know I am going to be downvoted for not citing, maybe someone who agrees can help back me up, and also for saying "chemicals" and there are people here who cringe because everything is chemicals and most chemicals are good, I want to be clear I'm talking about the bad chemicals here- PFCs like the ones in the article, heavy metals, other petroleum-derived baddies, and some others.
But that gets us back to the "Theory is closer to practice in theory more than practice" problem.

some type of recommendation engines works really well especially the collaborative filtering types.

Exactly what I was asking about, because I'm not so sure. Furthermore, I think it's a category error to include collaborative filtering here, which is not automated/ML/etc.
Yeah, so: Research it, ask professionals about it, weigh the risks, and come to a decision, or don't. It's not like we're just computers who run every piece of input as a command with root privileges. We can engage and use a healthy, non-black-and-white filtering system.

27 Styles of Rapping
I think that it's a problem when we talk about the outputs of different forms of verification as if those things shared a common identity. They may share a similar property of undeniability, but they are not the same thing, and in point of fact, they are not comparable. The phrase "freedom is better than slavery" is not better or worse than "1 + 1 = 2" or "water boils at 100 C". I think that the idea of a singular thing called "truth" is actually fairly harmful.
I like it as well and find it delightfully easy on the eyes.

Funny thing is that I remember that back in the day I hated those Courier-font-style publications. They always seemed hard to read compared to well type-set documents. And I never understood screenplay writers obsession with Courier 12[1].
I guess the web is so noisy and cluttered today, that even harsh black Courier on a white page is a relief.

[1] Screenplays are usually written in Courier 12. I only know that because I sometimes read screenplays, for movies that interest me. It's fun and doesn't take as much time as it does to watch the movie.

But does it change the taste of the meat? This is the real question and a deal breaker for many.

Grass fed meat is gamy than grain fed/finished, so I can imagine seaweed imparts an fishy taste to the fat and probably to the milk also.
You'd think the low salaries and easy immigration would have put TO over the top.
This just feels like propaganda from the meat industry. For every bit of scientific research touting the demerits of industrial-scale farming, the meat industry is incentivized to fight back.
