I worked for FB. I like the whiteboard problems and many other engineers like them too, and I enjoyed discussing or solving similar problems over lunch. That's probably why they're so prevalent in interviews -- I don't believe they actually predict a candidate's success in a company. Btw in college, I used to compete on websites like topcoder, spoj, etc for fun. The interview processes of many companies drastically favor ppl who did that in college, at least while hiring in the <10 year experience range.

edit: also worked for google, same story

edit2: I believe most people can learn to solve these problems because a lot of it is mixing and matching algorithms/techniques that you've practiced. It just takes time and practice and exposure to a wide variety of problems and crucially, confidence. I've seen people who somehow strongly believe that they're not the "algorithmic type" and will never be able to solve these even if they spend months working on it. :( I've tried and failed multiple times to convince those ppl that this is a very learnable skill.
Perhaps, but you have to weigh that against the cheaply-made programs that save people a lot of time but would never have got made (or would be decades late) if the author had been obliged to follow "best practices".
Aren't FPGA's used mostly to test/design a circuit that you would then go on to actually fabricate/build? I could be wrong but I thought FPGA's were stateless (meaning if they powered off/reboot you loose everything and have to set it up from scratch again).
Wow, for once I was an early adopter! I started around like age 22, hardened at 30, and started rage quitting at 35.

I didn't actually like my job again until age 38 when I found the right employer, because I got picky.
Supposedly some of the Xilinx 7 series FPGAs have been reverse engineered so there is a possibility of supporting them in Yosys (which is reasonable free toolchain). I've not been able to get much information about this, but you can check on the website: http://www.clifford.at/yosys/
Turkey can't change geography. They have to deal with Russia since Russia has interests in the region and a long, long history there. They also have to deal with Iran, Turkey can't start trouble with Iran each time USA /EU decide to. In the end, US /EU can cut a deal and Turkey remains on horrible terms with a neighbor.

Russia is a bad, bad partner. They have no money (compared to the West) and really no tech. They have cool weapons and oil though but are unreliable there too...

Not at all. I only use the services that are the most simple, down-to earth and privacy friendly. Then every time I hear about a data leak, big hack or privacy violation, I'm happy about the fact that it didn't hit me.

> Apple has had iCloud backup for some time now, including cloud camera rolls.

This doesn't help someone who never set up iCloud, has forgotten their password and/or methods of recovery, or any other list of problems. iCloud is a form of backup, by the way, and I specifically mentioned people that didn't set up backups. If you think I'm cherry-picking or coming up with some imaginary position, watch some of Jessa Jones' videos[1]. Many of her customers are in a position where they need data on their phones, and it's not in iCloud.

> You take the device apart and damage it in the process then why should the company stand by that?

They wouldn't repair it at all -- they were willing and wanted to pay for the repair. There were many arguments online why they didn't want to repair it (including that the Apple store couldn't get the parts from Apple, they weren't certified to repair it because they were still on the certification waiting list, etc). And of course you can't buy replacement parts because it's Apple (though eventually they managed to get replacement parts, it definitely was not by following the rules). Other manufacturers don't act this way.

> fine consumers sue them for every little thing they do

"little things" like manufacturing defective keyboards and denying that it's defective and refusing repairs or returns until enough people get together to sue them so that they fix a defective product? Or "little things" like using the wrong kind of capacitor near a GPU, causing GPUs to fry in almost every edition of the Macbook -- prompting recalls (or as they call them: "extended warranty programs") only after lawsuits?

I can't imagine why consumers would ever sue such a lovely company. /s

> Your first source is just some guy talking and nobody has the time to watch that BS.

The tl;dr is that 3rd-party (unauthorised) repair shops appear to be far more knowledgeable and reasonable about repairing iPhones and other Apple devices than authorised repair shops. If you'd like the longer form summary, watch the video.

> The whole concept of "community standards" for a worldwide communication channel strikes me as newspeak for centralized moral policing.

This is a classic case of the race to the lowest common denominator. When the "community" is so large and diverse and often in opposition to each other, there can be no good standard other than free speech. This is why we had such strange issues of white supremacist content along with gay rights and atheist content being censored. If you censor one group because some people are offended by it what are these tech companies going to do when pressured by china, saudi arabia, israel, europe, etc to ban content they find offensive. They would ultimately have no choice but to simply ban everything that everyone finds offensive or lose market share.

Sadly, I think this is just the beginning of the censorship wars. Tech companies have set precedent the past few years which is going to cause them a lot of problems in the future. Usually the young "liberal" people lead the way in tech but they are usually followed by the much larger religious and conservative groups. The tech companies might agree with the censorship requests of today, but I doubt they'll like the censorship requetss of tomorrow. An organized conservative/religious censorship movement that mimics the recent liberal censorship movement can't be that far off.

> Are FINRA truly 'regulators' (with access to state enforcement apparatus)

Pretty much. FINRA writes rules that everyone in the industry has to follow. When you work in securities, you agree to hand FINRA arbitration power over a lot of things. They can fine you and bar you from the industry. They can't press criminal charges, but neither can the SEC.
Yes they absolutely can.

Cost isn't a factor of value.

It costs $62M to put 22,800KG into LEO with Falcon 9. But if all I'm sending up is a block of concrete, that isn't going to have much monetary value to anyone. Indeed, it might have negative value (particularly if, when it drops out of orbit, it lands on someone's house).
After reading this one I'm not sure this is as bad as I thought it would be based on the headline:

"On new account applications, for example, behavioral biometric systems pay close attention to where and when applicants pause. A legitimate applicant typically types personal information — their name, their address, their Social Security number — fluidly, with few breaks. A scammer will often either cut and paste or take breaks to consult their notes."

It's currently used to do security checks. And it's being done while your interacting with the site/app. Seems like a useful security check, though I suppose there's some potential for abuse, somehow?

I think Google's CAPCHTCA thing does this too? It watches how your mouse moves and knows your a real person (or something close to that).

1. there was a real and direct power differential, which moves this very fast into „inappropriate, possibly criminal“ territory

Ross Ulbricht is not done with the courts because, contrary to popular belief and media reporting, the Supreme Court is not the last stop on the appeals process line.

Next on tap for Mr. Ulbricht is the time-honored 2255 motion. Mr. Ulbricht now has until next June to file a civil lawsuit against the US government accusing it of violating his civil rights and seeking the verdict to be set aside or his sentence to be redetermined.

Why bring it up? 2255's are far more likely to succeed than a Supreme Court petition (the high court gets more petitions every year and yet considers fewer of them every year). Why now? The law says you can't bring up a 2255 until your last conventional appeal is exhausted.

Further, the 2255 gets to be considered by the very same trial judge who convicted and sentenced him. While that's a foregone conclusion, the second circuit will no doubt thereafter be asked to consider that petition, and might decide to either set Ulbricht free or reduce his time to maybe 10 years or time served, given how ridiculously beyond the pale the original sentence was.

I wouldn't be at all surprised if Ross considered the Supreme Court taking his case as being a snowball's chance in hell for the year-plus they've been sitting on the case, and has just been looking forward to finally filing his 2255.

Keep watching. It might be about to get good.
Why AI researchers shouldn’t turn their backs on the military
There is actually little evidence here that a resonance excited by marching soldiers caused this bridge to fall. The article says that, as usual, the soldiers were instructed to break step when crossing. The article cites a powerful thunderstorm, the effect of strong gusts being 'caught' by the massed soldiers on the bridge, and corrosion of the cables at their anchorages, as likely causes. A survivor reported that the soldiers were stumbling around as if drunk, and could barely stand. There was some speculation that the motion of the bridge caused the soldiers to respond in a coordinated way that exacerbated the swaying, but lurching from side to side is hardly marching.

Contrary to what the grandparent post says, few bridges are susceptible to being brought down by marching.
Still don't understand why this story blowing out all of a sudden.

It's common knowledge that the biggest internet ad company likes your data and wants it for its recommendation systems.

If you want to turn off Location History, which is a feature, a product in itself, you can.

If you don't want your searches to be tracked, use another engine like DuckDuckGo or Qwant. If you still want Google, you can disable the location tracking. In addition, they provide a tool to see exactly what they store and you can delete any entry.

Also, of course Maps will want to know your location, you can turn off your GPS anyway. The only troubling point is the storage of the location at the opening for no reason I don't know if you can disable this.
One reason could be to meet real-time constraints or to get predictable timing. This is becoming more and more difficult to do with modern CPUs for all sorts of reasons.
> This seems intuitively wrong.

But it's still correct - there is no link there.

> If power goes up in value, it becomes more expensive to produce new Bitcoins as well as process transactions.

No it doesn't, because the number of bitcoins produced is a constant regardless of price, and they can only be sold at market price. If people stop mining because it costs too much, the supply to the market is entirely unaffected.

The cost of power has absolutely no bearing on the transaction fees or the transaction processing capabilities of the network either. Only congestion affects transaction costs, and the transaction capacity of the network is not connected to the number of miners online or the hash rate, it is roughly constant and dependent on protocol factors.

--edit--
- Replying to the child post here as I am rate limited :(

> If power costs go up 10x, the cost of operating the rigs that verify transactions goes up. Miners who find processing transactions unprofitable will remove themselves from the system

If those miners remove themselves, it has no bearing on the rate at which transactions can be processed or the price of a transaction.

They are all trying to validate the same transactions in parallel. The network does not get more capable as you add mining capacity.

> until transaction fees rise to a level that pays the bill.

What mechanism would cause the fees to rise?

(--edit-- last edit - I think what you're missing is that as the number of miners decreases, each miner gets a bigger share of block rewards and fees)
Timelapse video idea is a good one. Going to try that because it's so hard to be cognizant of posture all the time.
Indeed it actually may help lower the noise floor, as it would expose (through unusually precise, if idiosyncratic electron-counting metrics) the real cost of power expressed by inputs from both the acknowledged market, and the unacknowledged market.
Good answer from Physics SE on why there's no upper limit to temperature: https://physics.stackexchange.com/questions/1775/why-is-ther...
Please take my comment as constructive criticism. I'm sure you have good intentions.

I found your comment extremely patronizing to the person you're replying to. HN is an informal place where people feel comfortable to speak casually. It's not necessary to have perfect grammar in the comments.

Going through the trouble of rewriting their comment to be more professional implies that the original commenter can't write and needs you to teach them. Nobody asked you for a course on writing.

Also, HN is not primarily a place for finding work. If someone doesn't have an email in their profile, don't assume they are bad at job hunting. Maybe they don't want their comment history associated with their professional life.

Difficulty is adjusted every 2016 blocks based on the timing of previous blocks. So in the long term, the rate of block creation stays constant, averaging 1 block per 10 minutes.
From what I read on Italian forums, Italian engineers say that the materials that were used to build the bridge weren't the same chosen by the designers.

It will be a while before we learn the actual cause for the collapse, however.
> why the hell would you design a language and not use "=" as an assignment operator

That's one of my favorite things about Tcl. It just makes so much sense. Testing equality is analogous to testing inequality. It's a complex and context-dependent operation. Binding a value to a symbol is a completely different type of operation, and there's no reason for it to look similar. Keeping arithmetic in its own little space makes everything else so much simpler.

Many of the most interesting new languages I've seen which don't come from the C/Unix school use something different for assignment, e.g., Factor (Forth), Clojure (Lisp), etc.
There is a live stream from the bridge currently available on youtube:

>Bitcoin is surviving because its a useful application of blockchain. It was designed to be limited in supply, so people could store value without relying on a government currency, government land rights, or nuclear chemistry obsoleting gold.

>Alt coins are collapsing because dApps are unused due to the extremely high cost and unpredictable times of blockchain. There is no usecase.

That's all data that the IRS either has already or can collect more simply. So, because 20 million households can't have a form auto-filled, we should forget about the other 100 million?

The other upshot is that the expense and non-compliance from a tax perspective would probably drive more W-2 employees in situations where 1099 status is being abused. (ie. probably 40%)

Shocks me that you're getting downvoted for this because that's exactly what the results would imply. Of course that's in regard to the Extreme Programming always on, constant pair programming approach. Pair programming isn't totally bad of course, and has its place, but yeah the results would seem to imply that consultancy-style (I'm looking at you, Pivotal) pair programming is a good way to produce reliably mediocre code with a body shop.
