There's an article at the front page about WhatsApp and how they manage to do a lot with a little. Unfortunately, it doesn't go into much technical detail. I figured this article is more appropriate for the HN audience.

This is also a good article with a slightly different focus: http://highscalability.com/blog/2014/3/31/how-whatsapp-grew-...

Cash is King is Germany.

It's rather awkward if you come from a country with heavy card use. It's just weird to carry a few hundred euros in cash in your pocket these days.
The idea of recording on cassette has always appealed to me as a fairly cheap and easy way to record analog tracks at home with some of the older cheap 4-8 track sound boards. I think the limitations I'd set for myself and the change in my workflow vs a laptop with a DAW would have a pretty drastic change on the way my music turns out.

Do you find this is why most artists first choose to record to cassette, or is it because of other things like easier/cheaper distribution?
This could be true. But on the other hand it could also be that if we modify people to live longer lives that our brains will also remain plastic and malleable for longer.
I like it also. Pretty neat.
Let's hope that abject consumerism that makes you downvote this will also give you cancer.
Fair point, my HQ is in NYC I can attest to the 9 to 5 as well. I think it has more to do with transit scheduling than anything. Then again Paris is extremely expensive to live in the Metro area as well so that may have something to do with my experience as well.
Sure. They're also the first to respond to natural disasters.
With such paranoia as this, you also can bring the inventive genius of a nation down.

The US has so much talent, but when such things will continue to manifest, the terrorists already have won!

Perhaps the mods could merge/replace this (pretty bad) Wired article?

Stupid kid confused school with a place that supported learning and curiosity.

I'm pretty sure that I wouldn't make it through high school today.
I'm not sure how you managed to translate "Its not surprising 50 engineers are enough" to "I could do it in an afternoon"
A circuit board? There is nothing dangerous about a circuit board. In case you didn't notice, every bit of electronics has one.
Thanks for the nice words and bug report, I will investigate. Never had this happen to me yet.
A picture of the clock in question would have been nice for inquiring minds to see..
That's not even the issue to me. It's like fine you "suspected" it. How difficult was it to not suspect it anymore? Like did the arrest and the accusations need to happen. It's almost like attempting to traumatize the kid and his peers for no good reason and for what? Security theater? Because he was brown or a Muslim and did not know that brown or Muslim people should not bring electronics that might be suspected with them to school because they should fear being suspected? Perhaps we can excuse his ignorance for not being old enough.
Germany will have around 1M refugees in 2015 alone. Maybe 1.3M in 2016, maybe 1.7M in 2017? Considering most asylum seekers will bring their families(let's average 2 people more each one) along afterwards. That's only considering Syria.

Now think about Lybia getting worse(it actually is) -> Lybian refugees.

Wars in Eritrea, Iraq, Nigeria, Yemen! -> Other refugees ...

There are also refugees from not-at-war countries whose life is at high risk (Pakistan, Iran, Somalia).

At the same time consider that Greece can't pay its pensioners, Italy, Spain, Portugal are not that crazily better. High unemployment.

Other European countries such as Romania, Hungary, Poland, Croatia,etc are just starting to grow and match EU standards.

There's also a risk of importing their conflicts to EU streets - e.g. Kurds+Turks in Germany/Austria/Switzerland. There's been fights already in the last days in Switzerland and Stockholm.

I believe refugees should be given help and a safe shelter by sponsoring and building communities in borrowed land from Turkey/Lebannon/Jordan. However I'm of the opinion that inviting them to stay in the EU makes everything more complicated and expensive(which doesn't maximize the number of refugees you can help per euro) AND encourages the ones who can afford to pay human smugglers to risk their lives by crossing the sea.
The article mentions that this isn't happening here and that's the problem. It's not so severe that families die off but is severe enough to cause a lot of ongoing casualties.

The argument between Vinyl / Cassette / CD / MP3; I file under "narcissim of small differences". As I get older I find that emphasis on mindful listening reveals a richer range of sounds than any music source is able to match.

It is definitely profiling and I bet his race had a lot to do with it.

But I think the same thing would've happened if I had brought such a device to school - having been a super dark dressed goth in school, the fear would've been it's a bomb.

Schools are generally very very extra worried about everything these days, suspending him was unnecessary but with it only being three days I don't see it being a terrible thing. The record will get set straight.

So then this just falls back to being unfortunate racial profiling.

Lebanon resident here.

I was impressed by the crowd that turned out for the board meeting last night. Great numbers, unanimous support for the board to direct the library to continue running the relay, and lots of people stood up to speak earnestly about the value of doing so. Board members were happy to have so many residents come out in support of them.

The fact that supporting tor indirectly supports some less savory parts of the dark web was discussed at the meeting, but the general feeling was that the benefits far outweigh the drawbacks.
In an unrelated industry, Beechcraft (Hawker-Beech I believe it's called now) has a similar blow out. Too many managers and not enough actual workers making product. And to make it even worse, outsourcing integral parts of the aircraft to Mexico: fuel bladders, electrical components, and etc (and sadly they refused to properly train the Mexican workers in any of it). What are they doing now under Textron? Quietly returning those outsourced jobs to Arkansas instead of Salina (Kansas), focusing on making actual aircraft, and scuttling middle management and other other useless cruft from the company. Too bad no one with a similar attitude can just swoop in and buy out HP like how Beechcraft was bought out by Textron.
Maybe. And I fully admit that given those two choices, it's better to save the company and lay of 30k people.

But I do have to wonder how the company grew to be so bloated and large. Perhaps it was unfair for HP to hire them to begin with.

I fully recognize that at the end of a day, an unprofitable company doesn't do anyone any good. It's just sad for me to think that the only way to make the company profitable is to lay off such a huge number of employees.

I also know how big-company layoffs often work; they often don't take someone's quality of work into consideration, but rather the project or division in which they worked. Thus, I'm sure some great people will be looking for jobs, through no fault of their own.
There's a difference between knowing and trusting...
Immigration plus no welfare state was vastly better than the alternative of starving in ireland. It's also vastly better than being beheaded by ISIS or being paid 200rs/day in India.

But again, those folks don't seem to count.

I'm also confused by the collective responsibility you seem to allude to. How do you determine which groups this responsibility adheres to? Can "the Jews" rather than "Europe" also be collectively responsible for things?
You have the right answer sadly... It's just impossible to grasp the stupid amount of paperwork you have to fill for everything. As an example I needed more paperwork for my train rail-card than my passport (this is not a joke, it was really the case). In the UK, I just give a 10 pound note and I have my oyster card, no questions asked. My brother has a small business, it's just impossible to understand what the administration wants and they take ages to answer to stupid things we should not even have to fill, I really hope that one day, they will destroy the current bureaucracy and the country could finally have the place it deserves internationally. /rant
Sorry but no...

We have 7 billion people on this planet already and the last thing we need is for them to be living longer.

You can't fulfill your potential in 75 years? Why would that change if you had 150 years? Hopelessness in the face of death? I am 46 and that is not even in my thought process yet...

We don't need drugs, technology and genetic engineering to live longer. We need less poverty (better/fairer distribution of wealth), less disease, and less war for a better quality of life.

Who wants to be here in 100 years anyway? I don't want to live in a world of 20 billion people with little resources on a barley habitable world.
And same in the UK. Ultimately, it can be worked around if you find the right people in the right mood, but it's insanely annoying.

Sweden was the worst on that aspect. Most owners require that you have a company signing the lease on your behalf (supposedly to guarantee the rent, yet they generally refuse advance payments on the rent).
Anecdote/comparison: there is a guy on YT doing Taiwan motorcycle tours, one of the US guests broke an ankle falling off the scooter with no tourist insurance. They went to the hospital and asked to pay in cash. Xray, cast, emergency room, all in all few hours of work came down to below $1K no questions asked.
Apparently the authorities have determined that the best way to stop terrorism is to discourage any manifestation of personal intelligence, so that the population turns into mindless sheep. "If you don't know how to make a clock, you won't know how to make a time bomb" is their reasoning.

It is seriously disturbing.

I am reminded of stories of kids opening a command prompt and being accussed of "hacking", only this is a far more extreme case.
That's exactly where I stopped reading. I was thinking the whole time that the app should not alter the conversation directly, but only give prompts that can be used or ignored. It smelled of really bad design. Then I see an "artist" did that intentionally. Nope.

Young french here, yes its true mostly for workman and for functionary but there are a lot a people who work a lot (in startup and small buisness), the main problem is that people dont want to change their advantages cause of financial crisis and big worker union doesnt want to discuss about this.
Many Europeans look enviously at Britain and Ireland, which were granted opt-outs when the treaty was signed, and still retain full border inspections — with some notable success in stopping terrorists and catching illegal immigrants.

Meanwhile, some of us in Britain look enviously at the rest of Europe, where international travel, particularly by train, is altogether more efficient and friendly than it is to leave or re-enter our own country.

I also can't help noticing that those notable successes were apparently so noteworthy that the author felt no need to note any specifics that would identify them.
And while jade helm is still in effect.... The kid with the homemade clock was how "it" was to begin.
I just been reading about this morning and all I can say is what the hell is going on in Dallas? I mean when I was a kid I brought to school a model rocket with some solid rocket engines and all that happened to me was the rocket and engines were held by the principal until my parents could pick them up. But a kid making a clock gets arrested? Seriously, wtf is going over there in Dallas?

The portfolio approach to getting a job in venture capital
Honestly, I had a very similar thing happen to me at an even younger age. Almost got expelled for hacking when I was just making stupid shit with batch programming. Similarly, I made a crappy little audio amp a couple years later at the same school, and again, almost got expelled for "making a weapon and bringing it to school" (they thought it was a stungun)

All it did was make me anti-establishment at a slightly younger age. The kid in this story knows that what he's going through is bullshit, and he's likely to have something pretty good come out of this due to all the media attention. If anything, I'd suspect it would drive him to create more, because if there's something kids like to do it's sticking it to the man.
One thing I did with a friend back when XKCD 1110 came out: http://dump.ventero.de/xkcd1110/open.html

IMHO Seadragon feels much nicer and fluid compared to the host of Leaflet-based viewers that appeared on that day. But maybe I'm biased because I was involved in this viewer ;)
As well as a diversified student body, in my experience. And yet, no bombs.
I believe the GNU regex library also uses a hybrid algorithm.
To be fair it's a middle school, and most people don't really know what a circuit board is for. I don't think it's outrageous that they asked.

It should have never, however, escalated as far as it did. You're going to handcuff a kid who is cooperating and trying to explain what this thing he built is? Give me a break.

But worse still they're still not backing down. It's suspension of all logic and reasoning. They should have shown the clock to his engineering teacher and resolved the issue in minutes.
Icelandic research institute unveils ethical robotics policy
Many people move abroad because the world is a big place and it's a lot of fun to work and live in a remote country. For instance, I worked a few years in the UK, in the US, and I would gladly go to Asia if I had the opportunity. However I couldn't care less about tax, money or bureaucracy (although I"m attached to my short commute time and long vacations).

Besides, I noticed that many (most?) French students from the top engineering schools go to work in the financial industry (abroad but also in France). I often wonder if this should be qualified as brain drain too.
I'm concerned that typical electronics scare you.
The ESA and JAXA both seem to run approvals too. I'm not sure about their current plans/proposal request statuses the only ones a surface googling finds are several years old so they might be in between proposal cycles.
This is the debate. How much liberty are you willing to give up to catch a few bad apples?
Things are so different now. When I was in high school, all of the following were common:

- Boys carrying pocket knives/hunting knives.

- Boys with firearms in their cars/trucks so they could go hunting after school.

- Access to a wide variety of chemicals in chemistry class.

- Access to a wide variety of electrical and electronic components in physics class.

- Access to a wide variety of power and machine tools in industrial arts/vocational classes.
My current startup has a 9-5 culture, and we get a lot more done than any other startup I've worked for. No ping-pong, no long lunch breaks, no watercooler discussions, much less surfing on company time. I get more done in 8 hours than I used to get done in 12, and I get an extra 4 hours with my family.
There are certainly plenty of people for whom reading emotional cues can be a baffling ordeal who would probably appreciate this technology.

If you find circuit boards terrifying, you are on the wrong website.
So in your ideal world brown/Muslim children should not be encouraged to tinker with electronics. Or maybe they should just stay away from any form of engineering whatsoever. Does that sound about right cowboy?

Agreed. The best part is in the experience.

I love finding old records that used to be my grandpa's. Seeing his handwriting on the records on liner notes makes me feel like i'm sharing the experience with him. Digital can never replicate that.
So, I totally see why uncompressed music sounds better than compressed music ( MP3, Spotify, Pandora, etc. ) But, I don't understand the point of vinyl vs CDs. Nyquist theorem says you can fully recover an analog signal with digital sampling, if you sample frequently enough. So, there is no reason to have analog music. Am I missing something ?

I understand that you are using localStorage to reduce the number of requests to the GitHub Job board [1] (they probably has a rate limit) but for people with cookies/localStorage/sessionStorage disabled by default we just see a blank page. Can you at least wrap the code under the comment "// User" with a try/catch and display an alert explaining the visitors to enable localStorage in order to interact with the website? Otherwise this will be seen as another broken site to me, thanks.

> ability to organise my commits logically rather than temporally

I'm just getting started with Git; how do you do that? I googled it but nothing jumped out at me.
I think part of it is their awesome product design: their app has few features, but they are well thought out and enough to make WhatsApp very useful. Fewer features mean less people needed for development and operations.
It really saddens me that this kid (or other kids in similar circumstances) could find the experience so traumatising that they lose the motivation/interest to pursue these creative activities.
I recently started my own site http://computationalimagination.com for branded writing and interviews. I absolutely wouldn't consider publishing on medium. I just don't see any benefit to giving up control and branding. Any consistent audience that I build is mine with clear branding not: "Oh what was that good article I read on Medium the other day? The author, hmm Mike something or other?"

As a reader I never start at Medium - the only way I ever read something there is through references from HN or reddit
>Capitalism is built on the idea of everyone 'working' and 'having a job'

I think it was just built on the idea of selling stuff to people and making as many things as you can sellable commodities.

Whether those working are many or few doesn't matter, as long as you get to sell to enough people to make your profit.

In the days of advanced British etc capitalism, the homeless/jobless/disenfranchised living in London etc, were very many.

That you need to pay more people to be able to build a wide market is more of a 20th century addition (Ford and his workers, the New Deal, etc).
>The engineering teacher advising him to not show anyone else is just sad

Yeah, I suspect that he was trying to be diplomatic to some extent, but that's gotta be crushing for the kid.

"uninsured people pay way more"

A minor but important correction is they are billed way more, not necessarily pay way more.

For example I dated a girl who just out of high school with no insurance had a really badly broken arm (car accident IIRC) and the hospital "charged" her, in total, $100K+ as an imaginary amount, complained at her for awhile, and then they wrote her off after some token payment (more than they would have gotten in bankruptcy, less than it would have cost her in legal fees to file bankruptcy, but a moderately huge amount of money at part time minimum wage income).

Now whats important is the difference between the imaginary retail price of $100K and what it actually cost to provide services is incredibly valuable from an accounting standpoint. Also from a marketing standpoint her "$100K" of services was donated by a gracious company to the poor, they sure as heck don't publicize the actual cost of providing that service was only $10K even including minor surgery and recuperation. They did a good job, by the time I met her, I had no idea her arm had been so ruined just a year or two ago until she told me and showed me her arm, by no means did they cheap out on her care or recovery just because she was uninsured.

Finally the hope is that if they charged that poor girl a fair $10K then it would be hanging over her head for years until she could pay it off or more likely bankruptcy filing fees costing less than $10K they'd get nothing at all, but if they "charge" $100K then they might jackpot and she could qualify for some govt grant or fundraiser or whatever. If they know she's going to declare bankruptcy no matter what they charge and they're going to get $0 revenue, then game theory shows they should ask for $100M on the off chance by a miracle she wins the lottery, or qualifies from some weird govt grant or school support fund or something.

I think something foreigners often don't understand is we charge poor people $100K for a broken arm but we only charge them like $2K to file bankruptcy, so there are no acute medical problems that cost more than $2K, and for chronic problems they make life hell until either the chronic problem goes away and so do the bankruptcy bills, or the victim dies, but its not really expensive. The business model ruins middle class aspirations (how will I have the vacation home and RV if I file bankruptcy?) but we solved that problem by shipping off all the middle clss jobs to China, not having a middle class means not having to worry about a middle class anymore, there's just really rich people and peasants who own nothing.
My school had a rocketry club. Bringing this kind of stuff to school was encouraged.
> If you don't know how to make a clock, you won't know how to make a time bomb" is their reasoning

Do you have any sources to back up that claim?

It this really their line of thinking? Or did you just deduce this from their actions, i.e. that they seem to think that way?
