OTR kind of sucks, partly because of what you mentioned.

I'm trying to introduce the Axolotl ratchet (behind TextSecure's security) into XMPP:

https://github.com/rakoo/goax

The Axolotl ratchet provides true asynchronicity so you don't need to keep the link open forever. You don't even need the other party to be up; the message can be stored on either server and forwarded when the recipient connects, and the recipient will only decrypt the message at this moment. This is what we need.
URI beacons are pretty interesting. They can indeed replace QR in many situations, but I'm still not 100% sold on it due to privacy and spam concerns.

Those can probably be solved by using a 3rd party service to resolve the URL redirection, but we'll see how it goes.
> I would say even the food safety analogy is appropriate.

I think it's NOT appropriate. Of course, in the end, it's a matter of value: Do you value your health equally with your digital privacy, your money, etc.? If 'yes' then the analogy yes, if 'no' then it doesn't. I don't so, to me, it doesn't.

The Apple brand is really strong.

I was reminded of this recently when I started seeing a lot of tweets along the lines of "Now that I've been using the iPhone 6 for a while, the iPhone 5 looks like a postage stamp. I can't go back to such a small screen"

Only a little while back these same people would ridicule large phones.

Hi, AppGyver dev here. Our platform expands on the web view approach, allowing you to leverage existing web development experience when getting started.

Yeah, it's HTML and JS - but whereas Cordova provides you with one web view to build your app in, Steroids applications have multiple views joined together with native navigation. We ship with a lovely CSS framework by default to make building UIs a snap. The command line features livereload, so your changes can be reflected instantly on the device. And because it's Javascript, you can debug using the tools in Chrome and Safari - a vast improvement over printlns.

You might find this page illustrative: http://www.appgyver.com/supersonic/ui
One (slightly cynical) answer is that people like to hire people like them. Most quant types working in hedge funds are very good at brainteasers, and if other people are good at brainteasers it ticks one of the "this person is like me" boxes whilst also ticking the "this person is smart" box.

It also allows an endless pissing contest of comparing new brainteasers among your colleagues, and telling stories of helpless candidates who couldn't even manage the first gasp of a hint of an idea towards the solution.

I tend not to like extremely complex brainteasers as interview questions, and especially not ones that require an "aha" moment to solve them correctly, because mostly what you're testing for is whether the candidate has seen that question before (or one like it).

On the other hand, I am a big fan of asking relatively easy math questions (i.e. first year undergraduate) in interviews, because if I'm going to be paying someone $100k+ to work on mathematical models, I'm damn well going to make sure that they understand basic probability, statistics, calculus and linear algebra. These are a bit like fizz-buzz for quants - if the candidate can answer them it doesn't prove anything, but if they can't answer them then you can stop the interview right there.
Analogies are not meant to be precisely equivalent in every respect. They're just a tool to illustrate a certain point.
I'm sure a lot of people are fans of particular companies, but I think it's unfair to label anyone who expresses doubt in a class action law suit or newspaper headline as a defender of a company.

In a world of spurious law suits and sensationalist headlines, it's a savvy person who doubts stories like this.

And in reality, this really does sound like a bug right now. Maybe I'm an idiot, but I don't see any point in deleting a users music this way. Apple doesn't have a problem implementing unpopular policies that irk it's customers. So why be cloak and dagger about this?
Over a decade ago Portugal decriminalized drug use. You will not be considered a criminal if you use drugs, and will be treated like a sick person and provided help, by the government, if you want to cure your addiction. On the other hand, selling will take you straight to jail. If you carry drugs with you, the distinction between carrying for usage or for selling is the maximum amount allowed (in grams) which varies from drug to drug.
This has actually been the subject of (depressing) scholarly research.

The Math Trick That Smashed the Record for Factorization on a Quantum Computer

The UK isn't (obviously) as free with drug laws as Amsterdam, but here it's illegal to possess but not to use - aka if you walk into a police station smelling of weed and high as a kite on coke they can't arrest (or caution or anything) you for it, unless you actually have drugs on you that you haven't yet taken.

As such, if I witnessed a drug-caused medical issue, I'd get rid of whatever drugs were around (frankly I imagine if you put them in your pocket you'd be fine - doctors aren't allowed to inform the police about it unless they have a reason to believe you're a threat to the safety of yourself or others, and being a drug addict, short of being really close to killing yourself, isn't what that mean) and have no worries whatsoever about calling an ambulance.

edit: side-question, is there anyone on here who a.) knows what coke and white heroin are like and b.) would be willing to comment (with a throwaway if preferred) on: is it hard to tell them apart? I've never seen any form of heroin in my life, but find it hard to believe I could sniff it without knowing.. so wonder is it an easy mistake, or were these victims people who didn't know what to expect cocaine to be like in the first place?

edit 2: For anyone who hasn't been to Amsterdam, or at least the red light district... I've never taken them up on their offers, but the number of street dealers there... last time I was over there for work went out in the evening for a few drinks and some smoking, must've been offered coke over 10 times just while walking along streets. (And MDMA a couple of times, but not as frequently.) Never known anywhere easier to get coke if you wanted it, never known anywhere that I'd trust the quality of drugs on the street less if I had wanted it.
I can kind of see alcohol being a powerful evolutionary mover: water sources are frequently contaminated, killing off lots of drinkers, and the kinds of biological contaminants frequently are more deadly in the young, (yes animals get sick from drinking dirty water just like people) while alcohol can be a decontaminant and is often present with hydrating water as well as other nutrients and energy sources (like fruit) keeping drinkers of both alive maybe long enough to reproduce.

I've exclusively used Skype for video chat with family (who happened to be in a really infrastructure-poor part of the world) for months - it was by far the only thing that worked, pixelated low-res video notwithstanding. Most of the other clients, e.g. line, gave-up within 30 seconds with errors like "connection is unstable". Getting Skype to connect is a major pain but once it gets going, even though the video sucks, it isn't choppy and the connection doesn't keep dropping.

Also, I never faced any ads with Skype (not sure if that was due to $1.20 balance in my Skype Credit account). The aforementioned calls were over wifi on my side and 2G(?) connections on recipients side, so free.

There's a gradient between the abstract and the non-abstract. And, the artist decides the position on the gradient based on their communication intent, the subject (the perceived audience), and the object (the perceived thing), even if they're just 'doodling'.

I think Portugal's policy is great, but it's worth noting that they don't quite treat you just "like a sick person" - there are mandated treatments/etc. that they can (and will) force on drug users, rather than just saying "hey we're opening the doors to treatment should you want it".

They released a 10 year report in 2011 that basically showed drug use had gone down by nearly any metric since they changed the laws in 2001.

I'm only speaking for myself here, but I consider Apple to be fundamentally different from most other companies. Most companies seem to have their priorities in this order: Money, money, money, money, product. Whereas Apple seems to be: Product, money, money, money, money. The fact that they make such good products, and they are so far ahead of everyone else in terms of the focus on the product, that's why I'd treat them differently. I mean, if they do something illegal, they should get punished for it. But if another company does it, it's not the same - the other company was never thinking about the product or the customer, they were only thinking about profit. Whereas Apple truly seems to care, at least in some instances, about their products and their customers.

Think about what I just wrote, and tell me what does that say about the current state of the corporate world?
The article gives me the impression that the Curies' medical knowledge was primitive or nonexistent by today's standards. It makes it seem like they thought radiation would just magically cure cancer, like a philosopher's stone.

Does anyone know if this is correct? The article mentions that they knew radiation would kill tumors; did they know it just killed everything, but would kill the thing it was closest to fastest, or did they think it had magical specificity? Perey noted that francium would accumulate in tumors; did she know that tumors have faster metabolisms (the basis of a lot of treatments today) or did she think it had magical tumor seeking properties? If they were in fact ignorant by today's standards, were they ignorant by their own's?

> Prescribed Radithor by his doctor in 1928, Byers was dead by 1932 (aged 51), with his autopsy revealing that he had consumed approximately 1,400 bottles in afew short years — at least one every day. Radithor was a radium drinking solution promoted by one Dr. William Bailey (a fake name) whose products did in fact contain significant amounts of the element. The recognition that rich patients — and not just female industrial dial painters — were dying because of these products led “the federal government to act with far greater alacrity to help consumers than to assist workers.”

That’s implementation-specific. Not necessarily a hypothetical one-world government must work like the government that’s running your country or mine.
A custom spam prevention system, such as a honeypot or the simple "What's n+m?" field, works at 100% until your site is valuable enough for the attacker to spend a couple of cycles to circumvent the honeypot - then it drops to 0%. Publishing your solution as a module just serves to increase the value of circumventing it.

The value of "real" CAPTCHAs is that they retain their deterrence no matter how much effort the attacker invests.

In their words: "lower than expected growth". As Angry Birds were getting more and more popular, hundreds of people were hired to work on expanding the brand, but revenue levels did not increase in the same manner.
Brainteasers are somewhat common in consulting interviews (at the undergraduate level). The idea behind giving brainteasers is more to see how you would structure and break down a problem, and whether you can communicate your structure and solution effectively.
My kid and I would still be playing Angry Birds and he would still be asking for the merch this Christmas if I hadn't become extremely disgusted with the constant push to make in-app purchases and buy other apps. It's before, during and after every board, every retry. I stopped playing, encouraged him to play other things and I eventually removed it from all our devices, it hasn't been missed since. They should have stuck with a free app (no ads, no in-app purchases) and made money from merchandise. They had a good thing going with the Star Wars TelePods except after spending an embarrassing amount on the figures to scan in we still had to deal with ads to buy weapons and tools.
Most companies these days are about marking their brand and associated products as a certain lifestyle. But Apple may have taken that to a new high.

I've come across students who've had similar sloppy teaching and had to re-teach material so they could unlearn what they'd learnt and get a proper foundation for moving forward. Consistently, they would have very poor assignments for the first few weeks until they had that foundation.

> Low risks do not justify high expenses.

What is the expense associated with, for example, not concatenating user-supplied input in SQL queries?
The logic is sound, but doesn't play out in the real world that often. The reality is, the overwhelming majority of form spam comes from scripts and bots that are not that well-targeted, and in most cases, people who would normally install reCAPTCHA have no need for it.

Additionally, even though the module has been published for quite a while, and honeypot/time-gate techniques are fairly common, most bots can't account for the small adjustments that are made from site to site using adjustable settings for the module (like field name, time defaults, etc.).

The truth is: once your site or app is targeted by a human who is determined to spam you, the stakes are raised to the point where neither CAPTCHAs nor standard honeypots will deter everything. You will have to do at least some ongoing work to find a way to defeat the spammers.

Twitch has had massive growing pains, it's taken them a very long time to get to a point where they are smooth under load.

For a long time the LCS broadcasts were always very stuttery on twitch, so much so that streams were also set up on Youtube and Azubu to help.

About 6months - 1yr ago twitch suddenly got a lot better in this regard but I certainly wouldn't expect NASA to do a better job than a site dedicated to streaming. (The 12yr old playing the game is a red herring, they're just streaming to twitch.)

Twitch previously were Justin.tv but switched to gaming as clearly it was a fast growing niche, otherwise their old platform would have been suitable for factual content like this.
I work as a quant and I like to give brainteasers in interview. It definitely does not tell me if someone will necessarily be good at his job or a good fit for the team, but it does help me rule out a lot of potential candidates.

These are not very tricky brainteasers that depend on getting a particular insight. They're actually somewhat pedestrian. However, if you can't manage to competently work out a simple, well defined problem, you're going to struggle with the more complex issues we deal with.
With the "technological moat" SpaceX is building, does it matter how few customers they have today if no one can compete with them?

Didn't a SpaceX competitor install second-hand 1960s Russian rocket engines in a launch vehicle that failed recently? Its not a fault on the engines - I'm sure they were excellent - but rather an anecdote on the gargantuan barrier to competition inventing new space technology offers SpaceX.
Interviewers are (should) not interested in the correct answer. They are interested in seeing the candidate think out loud. They want to see how you start tackling difficult problems.
