Nearly every platform has something like EV - anyone can make a username or domain names that sounds official, some mechanism is needed to tie it to a real world identity.

Email/GPG has services like keybase, Instagram has verified accounts, WhatsApp does too. Even bloggers who dislike checking organisations for certs (EV) do so from verified accounts - though Twitter mistakenly tried to tie it to both noteworthiness and ethics, which they're now trying to fix.
When playing out I was often told not to come back until dinner, so we'd go off and do stuff.

When I try that with my daughter there is a 97% chance she'll end up at a friends house playing Minecraft or something similar (or she'll just end up in her room playing computer games). Personally I don't think the problem is so much that we don't let kids out, rather that there are so many other, screen based, things competing for kids attention. We don't have to ban kids from playing in the streets since we couldn't convince to do something that boring if we tried.
- Moderating communities sucks

- At some point you will have to make a judgement call as a moderator, if you have no written rules every decision is a judgement call

- Someone will not like your judgement call, you then get a discussion

- To make sure you don't waste time having the same conversation again you write it down

- Rinse 'n repeat, you now have a CoC, whether you like it or not

I haven't tried oBike as I am already customer of two other bike rental schemes in my town (Munich) but from what I see when looking at those and from reports they are really bad in quality and comfort.

As an example here a (German) video comparing oBike and a "normal" bike rolling down a small hill: https://youtu.be/9bTnwJc5gzc

There are probably better ways to spend those bucks.
Fictitious route names from a neural network trained on UK Climbing logbooks
When the author pointed out that bitcode may impact security, I expected to read about how compiler optimizations that happen during compilation of LLVM IR to machine language may introduce security issues.

However, the article only mentioned that decompilation is easier with LLVM IR, because it is a more high-level language. It certainly is a valid point, but addresses the topic of binary obfuscation instead for algorithmic security.

I'm thus wondering if anyone can shed some light on the real security aspects. For example, let's say that I compile C that is supposed to run in constant time to LLVM IR and submit it to Apple. Does Apple guarantee that their blackbox optimizations do not introduce branches or other factors that may result in variable timing into a constant time algorithm? Can I do anything to ensure that my code will always run in constant time despite unknown optimizations being applied to it in the future?

For 1), I'd randomize with proportional unit (share) representation, and I'd certainly be open to rule-prioritized execution (e.g. most-favorable taker first) if it didn't lead to degenerate incetives. Smart market design can incentivize people to play at their best price. For example: locational marginal pricing in wholesale energy markets...

2) I agree that the real world is quantized, but I think that a settlement tock to the bidding tick could be used to reduce the value of proximity. IEX actually implemented general latency with long runs of fiber, which is a really elegant fix. They couldn't make the rest of the world latent, so it's something like 700 microseconds, enough to remove colocation advantages, but only enough to solve for New York.

3) As far as I know, HFT's like to play in limit order and derivative books. It's where practices like flashing and spoofing have come from. Market orders are fraught with peril, especially if you don't know the matching rules for the exchange. As far as tightening the spread and aiding price discovery, I don't think that those two things are the same. If a security has naturally low volume, responsive high frequency trading can effectively be predatory.

4) I agree that there is more to HFT than just speed, but I view high frequency temporal arbitrage as an unnecessary market feature that provides the illusion of liquidity right up until that liquidity would truly be useful (since robots get benched when things go strange).

Granted, the temporal steps that I'm advocating here are a little provocative. The US could be solved in something like 200ms, and larger global markets, like currency exchange, are already fairly decentralized (though not as much as they used to be, as far as I know).

Either way, I don't think that NASDAQ can assure global temporal coherence, especially without controlling the entire network. Given that, it makes sense to design robust systems that don't pivot into rare modalities in exceptional cases. Just pull clock slew off the board.
Basically it looks as though the Ticketmaster site was accessing dependencies for the Inbenta componenet (customer service chatbox) on a third-party site (Inbenta) which was then hacked. Presumably then the hacked Inbenta component was slurping the payment details from elsewhere on the page.

There are so many links in this chain of wrongness its hard to know where to begin.

Don't run code from a third-party site where you're processing sensitive information.

Even better, don't use silly chatbots.
Ask HN: How to find a developer job when your heart isn't really in it?
I have been funemployed for about 6 months now, and enjoy it very much, never been happier. I've had lots of time to read, tinker, relax, and enjoy a stress free no BS life: no pointless meetings, no politics, no arbitrary deadlines, no emergencies. Only good fun, family time, and health.

I have to start looking for a job again soon because money is running low, but I can't get excited about any job listing I come across. If it were up to me, I'd stay unemployed for ever. I love programming on my own time, not so much for work.

I enjoy programming as a craft. However, there is nothing "exciting", "revolutionary", or "passionate" about writing yet another CRUD app, maintaining your legacy code, or yet another crypto/blockchain app.

Most (all?) employers expect you to live and breathe your job, and working as hard as if it were your own company. But I don't feel this way: I chose to be an employee because I don't have the desire or stamina to start my own thing. And to be honest: I don't care about your made-up deadline or self-imposed constraints. Why do we (file and rank) all pretend to care so much about the owners' and the investors' bottom line?

I'm an average developer, I don't suck but I'm not amazing either: I've only every worked for companies you've never heard of and would never pass the interviews for the big names, I don't want to relocate to the US anyway. I have 6 years of experience, got better at programming with every job but never promoted, never interviewed candidates, and not interested in management (too much stress and overtime).

How do people here reconcile your need for income with the daily office grind?

How do you apply and interview well when all you really want is to do your job 40 hours a week at most so you can afford a living and not think about it outside of these 40 hours? Obviously no employer wants to hear that.

Not to be dramatic: how do you survive the trenches without dying a little bit inside every day?

1)how to optimize volumetric versus surface heating versus air/water heating of food. Once you understand enough about heat transfer, combining microwave, broilers, hot air and sous vide type cooking let's you create food textures that are better suited for your personal likes. Like cooking a turkey, people that complain about it being dry don't understand the difference between heat transfer and mass transfer.you don't have to dry out meat when heating it.

2) this is for food science, not food engineering.But yes, my this is a new area food companies (and specifically my boss) is getting into is to use AI/ML for understanding process and recipes to design new foods or troubleshoot problems

I think the niche qualification is inappropriate here. Lisp spread ideas around. Most dynamic languages today are basically CL in different clothing (lua, python[1], javascript, php ...). Even cpp is looking a lot more lispy these days with auto and closures.

Methinks that lisp value is exploratory, when you want to go crazy deep, you use it to mold every bit of the language as you want and try paradigms/principles.

ML or Haskell are also used a lot there but I think it requires a bit more apriori planning (separate grammar / semantics, typing, denotational mindset). Whereas lisp is more hack it until you make it.

[1] and if you look Dave Beazley fantastic video talks about "abusing" python metalevel, and compare it to CLOS you will find the difference to be more hard to discern.
Atari basically created, and then almost single-handedly destroyed the entire American console industry.

Despite their early success it was so poorly ran. Management was horrible. They were releasing piles of shit as games, like Pacman and ET. Programmers left the company in droves because of poor pay and treatment. Atari poorly handled the third party developer situation.

Their hardware was terrible. The 5200 and 7800 were flops. They couldn't get any traction in the home computer business.
I heard a recent radio ad pushing a "Work from home as a Medical Coder" training seminar. Sounds dubious.

I wonder if you could create a legitimate service that provides "Work from home as an Essay Grader."
First off, that sounds like baseless speculation. Second, there might be a causal relation between lacking motivation/interests and being jobless. It's not a representative sample of the population at large.
From reading the spec it seems that is undefined behaviour for anything other than `&b + 1`. That is one past the end of b is fine but not `&b + 2` etc.
I kind of a hoped it'll end up a joke saying "Don't use mongo". Last time I used it was 2.4 and it was the worst db experience ever. Back then It was more sane to craft a solution with PG and HSTORE. Now, I think RedShift does the job, why would anyone use mongo on production for anything today?
Just a general advice: Only do what you are passionate about. You are not fair with your employer if you are there just because of the pay and producing subpar results because of a lack of commitment.
I am not sure about dying. Any time I need to use Clojure I have all the libraries I need and if I don't it takes me very little time to write a small wrapper around the Java library that provides the functionality. Saying Clojure is dying is the same as saying Java is dying. There are unmaintained libraries, no doubt of that, yet, it does not mean that the entire language is dying. Java8 was a great improvement for Clojure and I expect more coming down in the pipe for later Java releases.
They also get dumped every where. The oBikes look awful too. Ofo bikes are of a reasonable quality but obikes on the other hand have never tempted me to use them.
I'm struggling with motivation
my suggestion here is to check "discipline beats motivation" ( https://iheartintelligence.com/2016/11/17/discipline-beats-m... ).

You don't need motivation, just discipline to build habits... it's non consequential whether or not you will ( eventually ) change jobs, everywhere will be a challenge if you lean on motivation.
But that's not the way NNs work. NNs learn classification on a particular representation only. From the NN perspective, this kind of description is exactly zero samples (of the required representation).
It would be fair if they would provide accurate weekly production numbers for the last 6 consecutive weeks. Maybe the pattern was: 3000, 2000, 1000, 1000, 3000, 5000... Which is quite different than pattern: 2500, 3000, 3500, 4000, 4500, 5000...

Could you write a blogpost about all this complicated hft stuff? Thanks
I agree with you. But consider the capacity of a healthy individual, now spending 30 minutes or more, focused on a single task. Doing low intensity excercise without doing anything else...is an utter shite use of valuable time. It's just a waste of time that could be spent getting the heart rate higher, the muscles full of blood, etc.. I agree that it's beneficial but barely. Low intensity is good for getting people who don't workout to start lifting their arses a bit. But it has hardly any substantial effects on a healthy individual as compared to lifting or sprinting or jogging.
Actually, you should not expect that, because you don't have a guarantee of ordering of the addresses of a and b on the stack.

Slightly off topic: When in high school me and some mates actually found a dead body in the canal.

This was not in Amsterdam but Utrecht, which has very similar canals. My school was right on the canal and it was an early winter morning. Turned out it was a homeless person who probably fell in while drunk, at least that was what the police said. Not a nice morning...
Can you give some specific examples?

That it's hard to follow is beside the point (and it's hard because this particular character is rather complex, but I wanted to pick the character for "picture" as a pun; some characters are much simpler, and could be very easily described, while others are far more complex). People are capable of doing that, and do it all the time (maybe not with characters, but certainly with other things). Sure, it requires prior knowledge, but that we can do it and do it often, suggests that perhaps most forms of high-level learning internally build this "tower of abstraction". One could claim that the internal layers of an NN do something similar, but that's not quite accurate, because the backpropagation process is global, rather than modular.
So much this, even if you can create a decently accurate ML system to score student essays it absolutely doesn't handle the adversarial nature of scoring and is frankly insulting given how much students are paying for tuition these days. The problem is AI-complete.

Its a good tool for feedback and its acceptable for a MOOC or low-cost courses as long as there are adequate disclaimers and the student's final score is determined by a properly human graded assignment or exam.

I agree that it might not be the perfect place for you to find an answer to your question but will add my anecdote nonetheless.

I am 32 and lots of my friends around started to have kids ~ 5 years. I can see that one of my friend has 3 kids that appear to be normal in every way. I have another friend who daughter is exceptionnaly advanced for her age (she speaks two languages already and started to speak earlier than the others kids). I have another friend whose kid started to speak pretty late (~ 4 years). So if you try and compare your kids with what a "normal kid" should be like, I think you will develop gray hair fairly soon :)

The best thing to do is to talk to your pediatrician and see if there's an issue. Don't hesitate to talk to different doctors if you want different opinions but I know that most parents try and compare their kids with the other to see if theirs is "normal". I think your children will turn out to be just fine and I don't think they will have any sign of mental issue at all - you're just a scared parent and it's OK.

Take care,

Edit : corrected some spelling mistakes

I highly recommend using f.lux to adapt screen colors at night. It makes reading some pages harder once it goes into full candle-light mode, but I take that as a signal that I need to start getting ready for bed!

> Java is dying, not on the whole, but certainly in mindset of people who are picking new languages

Even as a whole it's slowing down heavily now, even Android is switching to Kotlin. The language is already not that trendy but Oracle's aggressive lawsuits is making it even worse.
Bugs aside, ET actually isn't a bad 2600 game at all. A lot of the crap it gets is purely meme driven.
I think it works slow and not good on Android and Chrome here.
I like the behavior of the compiler here. There is no guarantee that a and b are next to each other in memory. That's why the comparison fails, the alternative makes is runtime/compiler/optimization level dependent which would be a total mess.

As usual with those C bashing articles you won't run into trouble if you don't try very hard to write contrived code.
I mean, the moment you see:

int *q = &b + 1;

on your screen alarm bells should go off. Doing pointer arithmetic on something that is not an array is asking for trouble. If the standard should be amended in any way it should be undefined behavior right away you do pointer arithmetic on non-array objects.
There's a guarantee relative to the address of b. But there's no guarantee about the relative addresses of a and b themselves, i.e. where they are placed in automatic storage. So even setting aside the idea of optimizing the test away at compile time, there's no guarantee that the comparison result will be a specific value. a could be above or below b, and they are not necessarily adjacent objects.

Sorting strings by generic comparison is very inefficient regardless of the algorithm you choose, especially if the long prefixes repeat, which is the case for FS paths.
I agree, how do you do it in practice though? I can't believe most people are passionate with what they do for money so where does that leave us? I would never write code for any company if I didn't have bills to pay but that's the best skill I have to offer, and I need to make a living.
There's a few reasons to throw away a case, and I make no assertion that these are why -

* they've identified a legal or technical reason that would render their evidence invalid

* may give up information that would let someone identify which towers are stingrays

* may give up information on where they are or have operated

* may be protecting some not-yet published or not yet well known exploits of the cellular network

Well, foreign versions of these have been found on US soil. No doubt we've deployed them internationally as well. Spies gonna spy. And it seems safe to assume that naughty hackers probably prop these up at major events for fun or profit.

You do seem to be missing the point that history shows that people do not migrate in large numbers, outside of war, famine and other natural disasters.

Even with open borders Chinese would not migrate at that rate when they are in a very different economic state to Greece. China is a place to migrate to rather than from as it grows in world status. It's inconceivable they would leave at that rate without first being a basket case (difficult without a Euro-comparable situation), or war and the traditional causes of significant migration.

Has EU freedom of movement resulted in dissolution of sovereign states? Did the absolute and total freedom to migrate by the two major empires result in the dissolution of UK and France?
