As part of an interview I did recently I was asked to build a web app that mimicked a part of their service and deploy it somewhere for them to view. I probably spent about 15-20 hours on it in total and I believe I did more than what the brief asked for only to be told I did not get the job with no explanation, even after I asked if they had any feedback.

I thing is I don't think anybody even looked at what I made because to view everything in the app required the user to login (part of their brief) but no new users showed up on the site at any point. Pretty frustrating experience overall.
They are not gone. They just said this to prove the point that ICOs are easy to scam and some structure is needed.
Might make it more expensive to hire, favoring insiders who are employed at the expense of outsiders. Also makes it harder to switch jobs if you’re unhappy/deserve better.
This is fairly sad, because a lot of software is still maintained using mailing lists. Often not because it's the best solution, but because it's the least bad (for some). Also, if one wants to ensure that the whole lineage will be with us 20 years from now, a mailing list is a better bet than all the Gerrits and Githubs of the world.

I remember I wanted to check out what was happening in Postgres, since it's my favourite database. But the sheer complexity of getting to the code diffs and comments and all that... I quickly gave up, because the environment was rather unfriendly to newcomers (actually, I didn't completely give up, I just browsed the Github mirror, which was the only usable part of their version control).

And I'm not blaming them, it works well for the core devs, but they can't expect many new contributors (and contributions are even things like documentation, tests etc.!). Which is a pity.
I feel like I'm missing something. I can't understand how it's more likely for a car to hit a cyclist on the sidewalk than the road. Cars drive in the road. They do not drive on the sidewalk.
What is the best free university from MS in Computer Sciences?
What are the best computer science universities that also offer assistance ship to foreigners. My current only choices are NUST(world ranking: 500) & Fast Universities in Pakistan. People tell me education in Germany is free.
Yes, but the sequence of bits that has been transmitted over the Internet is finite. That makes panic’s argument technically true.

Since we’re dealing with a sequence that’s zettabytes long, I’d guess it falls under the category of technically true but irrelevant.

"the proverbial "rat race" isn't really about about money; it's about social status. Most people don't real care about money, they just need it to buy status symbols with."

My thought is that money helps covering the Maslow's hierarchy of needs. Social status is present only in the upper half of it. This should mean that people may care about money but not yet about status. (And as a fun fact, the causes that leads to a "rat race" are harder to ignore as one climbs down on the same Maslow's pyramid, which at least in theory means that it should happen less for social status than for other things.)
> I just can't imagine they are prepared

It sure seems that way and I find it amazing. It has been known for a long time that the GDPR will come into effect in May. Maybe they thought they could lobby it away?
Serious question: if the processing problems are classified as NP, then couldn't that processing be outsourced to a blockchain? Why have miners solve for useless problems that have no long lasting impact like "number of zeros in a SHA string" instead of processing data such as this? I can easily see it being the case that the mining problem in a given blockchain could be based on real scientific problems that needs solving.

I'm looking for someone to help me understand why the above isn't possible.
Not contradicting, worth pointing out for the Americans in the audience: even if you have an exclusively US-based company, working with any EU users means you are in scope for GDPR.

The consequences for violating GDPR are quite severe -- up to 20 million euro, or 4% of global turnover, whichever is greater. Again, this applies to US companies even if it's a single record of EU personal data.

Furthermore, individuals are fully entitled to sue in the event of a data breach, and there is legal precedent in the EU for compensation of between 10-15k euro per person.

As to the question of EU law applying in the US, just look to financial regulation like Sarbanes–Oxley to see it going the other way.
The lack of self-awareness in this comment is astounding...
Did you read the original investigation (the one referred to in the submitted article)? It says quite clearly that Reveal was given data from Tesla's internal tracking system.

Well, only screwed if they want to keep their account? I can assume that resulting in Facebook closing down your account.

All in all, I doubt millions of people will request data under the GDPR. But I guess the fines are significant enough to worry about it.
The bug was fixed on January 26th and was being merged to older supported branches expeditiously -- I don't know the exact version numbers but I'm sure that any releases they rolled after mid-February would have the fix.

Is the tutor fair and unbiased?
Very few companies (care to) understand GDPR and the full extent or its reach/scope. Most think that it's all about "adding the privacy policy to our website" and that's it.

When the flood of letters starts, THEN they will feel the true pain/essence/extent of GDPR.

E.g. when my bank will get MY letter asking them who they share my data to, and asking them to STOP sharing my data with friggin FB (WTF???) on their app.. it will be fun to watch them squirm.
KPS-1b: first transiting exoplanet discovered using amateur astronomer's data
No, it really is just a couple of fancy words strung together.

Let's deconstruct it:

1) Space -- Einstein has shown that it's really Space-Time
2) Mind -- there is no real agreement on what "mind" means. Brain? Consciousness? Brain is well defined, consciousness no so.
3) Time -- the 4th dimension of space-time, right?

So "Time is the Mind of Space" deconstructs to: "the 4th dimension of space-time is <something to do with thought or thinking or consciousness> of the other three dimensions of space-time."

Focusing on the “what to do instead”... There's an interesting suggestion at the end:

> Holiday’s company [CallRail, Atlanta, GA] now uses a structured “live-coding interview” format that involves reviewing code together and talking about it. The process typically takes between 30 minutes to an hour.

I wish there were more details, like whose hands are on the keyboard, or whether the interviewer has a rubric to structure their evaluation.
Google could easily protect the privacy of their users but it would need to be a directive from the top down and they would have to actually mean it.

All this is is an attempt to show themselves as the good guys relative to Facebook whereas Google is in many ways just as bad, just along different axis. At heart both Facebook and Google are advertising scum of the very worst kind that hold the world hostage with some free functionality.

The problem with Google is that that functionality is of a grade that it is hard to get around them, Facebook you can do without just fine.

Sites aimed at the enterprise message “trustworthy” by looking distinguished and a bit grey along the temples. Sites for databases and file systems doubly so. You don’t want to trust your data to a kid, no matter how smart.

Because:

a) it is not possible to tear it down and start over with good material/intentions/ethics

b) they do not want to change their model, because they are making money from their current practices

c) it is a VERY useful tool for evey government's dark/shady practices (gag order + give-us-everything)(exactly what every dictatorship does)

d) people need to be protected even if they don't understand the risks (e.g. houses are built following a code - even if people don't understand that walls need X material and I-beams need to have Y width).
I believe it is just a manner of speech to talk about the extremes to claim the innocence of your defendant. Without such examples, declaring Stack Overflow as a saint would sound dull.
My somewhat embarassed apologies.

I have confused RocksDB with CockroachDB.

My understanding is that, at the time of development, Rocks itself did not support multiple writers. This was in 2015, or maybe 2014. At this point it looks like TransactionsDB might cover that, but I was not super familiar with that particular project, nor am I super familiar with RocksDB in general. I do know that they asserted Rocks could not handle multiple writers the way they wanted, and they needed something which handled SSTs well. Rocks was chosen and the shim layer was written on that assumption.
An unintended side-effect of this stunt is that it showed how strong convictions ICO experts hold about their recommendations: https://twitter.com/SatoshiAnswers/status/986645861655633920
Would the solving of the problem have a "difficulty" that could be adjusted to ensure that blocks appeared approximately every ten minutes?
Is checking that the solution is valid a very fast operation?
Are we sure that there is no "final" answer which would make the calculation unusable at some point?

Or if you're in Austria, you are conditioned to accept that delivery dates offered are 1-2 days off. The warning about "purchase within the next xx hours to receive it in 2 days" is absolute garbage. And the fact that I can select whether it's delivered on Saturday is bullshit, because no courier service here ever delivers anything on Saturday. Yet years later, my Prime packages are still being offered to be delivered on Saturday. I guess I shouldn't complain though, their estimated delivery times are still on par with every other eShop.

Generally, blockchain "mining" requires a problem that is hard to solve, easy to verify. If I understand it correctly, the genome sequencing problem is hard to solve, hard to verify.
THE WIRED GUIDE TO INTERNET ADDICTION
Extraordinary volume in the sub $35,000 bracket.

Europe's auto money makers are Germany's ~$35,000+ vehicles from BMW, Mercedes, Porsche, Audi.

Toyota, Honda, Hyundai (SK), Mazda, Suzuki, Kia (SK) and Nissan combined dominate the mid cost or lower vehicle category at massive scale. Volkswagen has been battling Toyota for the total sales crown, however Asia has a bunch of other companies competing at high scale in that bracket as well. I don't know what the volume comes out to, but I wouldn't be surprised if Asia is selling more than 2/3 of all cars in that segment globally.

I thought about this as well before, but the problem is that you don't want just ANY NP-problem: You want an NP problem (it doesn't even have to be NP-complete) that you can easily adjust the difficulty.

How do you adjust the difficulty on something like this?

Also, you always have to calculate the "hashes" of the blocks. I guess you could encode a block as a graph and it's "hash" could be the smallest path that visited all the edges, but how useful would that be?

When I looked into this in the past, I stumbled into Gridcoin[1], but I don't know how they deal with the difficulty/usefulness of the solutions.

They can seize money transfers en route to Facebook from their EU customers.

Facebook receives billions of advertising revenue from Europe (IIRC some 25% of their global revenue), all that money can be trivially seized by authorities, they just need to file the proper request.

Furthermore, there are international agreements on cooperation against tax evasion; I'm not aware of the details for this process but I assume that they could and would use the USA legal system to enforce collection of legitimate debts.

(I have a comment that may be relevant to some other observations here, but mostly unrelated to the piece itself, amusing as it is.)

To understand the USA, and modern politics in general, I find it very helpful to know a little bit of Roman history. The US were deliberately moulded by the very knowledgeable founders as a revised and improved version of the classical Roman republic. The attempt was wildly successful, and measured by most any metric it widely beats the performance of the original system.

There is one crucial point to the original Roman republic: it was founded by aristocrats who were fiercely jealous of their liberty and equality to each other. Their collegial Senate ruled since they killed their king around 509 BC, until they killed Julius Caesar some 465 years later - republicans have this 'sic semper tyrannis' thing for assassinating monarchs.

A second point is that republicans have a tight lock on the perception of the advertised virtue of their system. Whether it is actually better for the plebs, or the whole of society, to be ruled by a senate or a monarch is never to be left in doubt.

Augustus craftily shoved the monarchical empire down the aristocrats' throats by claiming the whole time that he was merely making the republic function as intended. However the immediate successors had a tougher time, and were quite probably historically smeared by senators who resorted to pens instead of swords.
I'm waiting for recruiting doctors like that. Oh, you are a surgeon with 17 years of experience? Cool. How about you make a surgery at home, record it, and send us a video?

More pathetic are only companies which have only one question at the beginning (without any further contact) "how much do you want to earn" and after that there is no negotiation. Sometimes I feel like I'm drowning in an endless sea of candidates. Oh, wait, no, the same companies publish the same job ads over and over for years. So maybe not.
I’m going to assume that, being a human being, and having a daughter, she has a social life in the city she lives in. To tell her she’s forcibly (by means of economic coercion with potential state violence to back it up) no longer to live near her social and support network is completely unethical, in my eyes - otherwise is to suggest that only the rich are allowed a stable life. No man is actually an island, as much as that is the American ideal. Replace “housing instability” with “being kicked out of their homes and told to live somewhere multiple hours away where they don’t know anybody”, and you get the actual problem.
I wonder if that changes now again back to better values. Crazy

It's difficult to generate hard instances of problems. Many (all?) NP complete problems are easy on average. For example almost all uniform random SAT instances can be solved quite easily.

Agree. I have definitely gotten good value out of his stuff.
Come on, 5 instructions per BF operation? They're on x86 right? Let's assume your memory pointer is in ebx. (Substitute rbx for x64 code) (nasm syntax)

+: inc byte [ebx]
-: dec byte [ebx]
>: inc ebx
<: dec ebx
[: cmp byte [ebx], 0
jz endlabel
startlabel:
]: cmp byte [ebx], 0
jnz startlabel
endlabel:

That's ignoring . and , which I expect do not occur very often. (If they did, their compute-focused architecture wouldn't be a good choice anyway.)

This is more like 1.3 instructions per command. How did they get their "5"?
> Would the solving of the problem have a "difficulty" that could be adjusted to ensure that blocks appeared approximately every ten minutes

I am fairly certain you can design your problem to behave in a similar manner or in some manner that increases the complexity based on some criteria

> Is checking that the solution is valid a very fast operation?

That's the NP part in my question. Plenty of scientific problems out there that are fast to verify hard to compute. Ex. Prime Factorization

> Are we sure that there is no "final" answer which would make the calculation unusable at some point?

I would argue, and I might be wrong due to my ignorance on the subject here, that we can never "know" that. That's why P=NP is still an open question
Also, given that she’d be living on the edge of affordability for the area, she could never put her feet down and build a lasting social/support network - she’d be forced out again in under a decade.
> You can’t control data on systems you don’t own. So Facebook’s options are either (a) limit how platform apps use data via non-technical/legal methods

Under GDPR, as a data controller, you cant share data with another organisation without ensuring that they follow the same rules that you have set out for processing data. This may get interesting in Europe.
My phone browser dies whenever I try to visit the website. Is there some kind of weird script running?
That's not my understanding of the NP domain. Take Prime Factorization for example. Which isn't even NP-complete, or Sudoku which is NP-complete. Both of these problems can be made really hard by changing 1 small variable, size.

Edit: I understand that your argument is about the average case and not the worst case.
TIL „blockchain ICO consultant“ is something people call themselves.
Maybe it's different in the states, because a lot of tech giants are based there. But in Europe, I feel like, there are banks that inherently have a lot of data and they can use BigData stack for ETL and other stuff, and there is the rest who just want to get some data on users and sell them some products they don't really want, it's not necessary an advisement company by itself, it can be an analytical platform or just a department in some big e-store.
For the reasons you describe, if a user simply clicks 'Agree' to something like the current T&C, it will not be considered as informed, freely given consent by GDPR and thus will not give the website any rights to process that user's data.
It's not how I interpreted the parent, rather it's more that this type of investment is probably based a lot on previous experience, not future potential. As such I think it's relevant. Maybe they're geniuses but they haven't proved that yet.
Occam's Razor is about the need of additional assumptions to explain observed behaviour. Existance of a god is a pretty heavy assumption, ergo that explanation is not the simple one.
What is Agile Testing?
Some places, yes. But surprisingly many places do a really bad job at encouraging internal recruitment, even when it would often let them identify talent they are unaware of and let them shift people into positions where they might be a better fit or be stay for longer. It's especially bad as it can often help shift more of their external hiring to lower risk entry level hires where a bad hiring choice has a lot less impact.
Parking meters in Montreal have bike rings. It's ingenious, in a sense.
Thanks for the link. I'll look into it!

> you can easily adjust the difficulty.

For Prime Factorization for instance, which like you say, isn't even NP-complete. You can easily adjust the difficulty by increasing the size of the number in question.
I'm waiting for recruiting doctors like that.

Would you want to work in a world where all programmers have to be trained, licensed and regulated with the same rigor as surgeons?

Surely the fact that programming is one of the few 'white collar' jobs where someone with no education and no relevant work experience can get hired based purely on the fact that they've taught themselves the necessary skills and can do the job is a net good thing.
Fixed - good catch.
I don't necessarily buy fully into all of these (I am in favor of homeworks, but they should be paid and later staged [this usually means more phone screens. can't win em all]). But since you asked:

1) because meaningfully large swaths of applicants are too stupid to fizzbuzz

2) because passing fizzbuzz is not the same as writing software

3) because teams are comprised of many people in many roles and just because team/person X likes you, doesn't mean you'll be a good aggregate fit.
One argument is that the blockchain problem coincides with a "real scientific problem" that needs solving and if the scientific problem leads to some application, which can yield a monetary reward (may be big "if"), this would make it cheaper to launch a 51% attack against this blockchain. The attacker could subsidize their attack by being paid to do science.
