Ask HN: Is it possible to be very good in multiple languages?
Is it possible for someone to deeply understand all of the following languages?
Python, Ruby, C, C++, Objective-C, JavaScript, PHP, Go

In the last 6-7 months, I intensively learned Python, and I feel I pretty much know all the important basic principles, I can write idiomatic code in it, I can optimize, profile and know the important tools and libraries. I dig deep into Django, I know my way around it at a level where I'm comfortable with it. (Of course I'm not an expert at all and don't even know the Standard Library deep enough yet.)
However Python is a pretty easy language.

What time would it take to learn the other languages at least this level, and is it possible at all to master 7-8 languages let's say in 5 years? If not, 10, 15 years?
(By "mastering a language" I mean that you are pretty productive and can get a well paid job with any of the languages you know.)

I already know that I want to do programming for the rest of my life, so should I pick one language/technology and stick to that and learn it very-very deeply, pick up one and two beside that, or should I go all-in and learn every language as much as possible?

I'm aware of that you should learn general applicable programming principles, theories, algorithms, math all the time which you can use in any languages, but I feel knowing the language itself is also very big part of the process.

Makes me wonder - will it ever end? We are nowhere even close to seeing this stop. Or is 1984 going to come out to be actually true rather than just a work of fiction? Orwell thought of the future in 1947-1948. Wherever he is now, I am sure he is going all "told ya so!".
Just be careful about biological material (NZ has very strict airport biosecurity) and you'll be fine. I'm a New Zealander and this is the first time I've heard of something like this happening at the border.
I've been on the fence about bitcoin. On one hand, the design is genius, with a few exceptions (mainly, the fixed supply). And it has garnered an incredible amount of publicity and usage for a digital nextgen currency.

On the other hand, and I think where I will end up, it's completely stupid. While the speculative benefits are terrific for marketing, they are totally incompatible for use as a currency. As is the apparent concentration of ownership.
Ask HN: Interaction score for HN posts
Besides score and points if we want to add one more attribute for HN posts which represents the interaction that happens on the post, how should it be formed?

I am interested in this data as some posts will get more points but if you comment on it no one is going to respond to you. The interaction in that post is very bad. Some of these posts are there even in the front page. Note: if OP interacts that post seems to be more engaging.
The moment that Bitcoin hit $30/BTC, it was over. The focus on BTC creating more fiat currency means that 99% of those with a position in BTC are missing the point.

Reading the link supplied by patio11 above (recommended), I wonder if using a hidden volume would constitute an obstruction of customs investigation.

"Don’t Obstruct an Agent’s Investigation

Once it’s clear that a border agent is going to search your device or other possessions, don’t take any steps to destroy data or otherwise obstruct that process. Like lying, knowingly interfering with a border agent’s investigation is a serious crime."

> why can't they demand your passwords to remote servers?

Because they can't read my thoughts? At least yet :-)

Seriously, if you have a VPS and remember the IP address or the domain or whatever, how can they find out? Don't use SSH keys and/or delete the known_hosts entries. Use a password to login to the server. Voila.
Those providers can't offer better prices because they pay wholesale from the monopolist and add their business on top. They can only compete on service. That's nice, but I want to pay less overall.
This is a late reply, but just in case you read it.

> I'd say there's valid reasons to dislike Apple's stance on many issues.

That's not apple hatred, and it's not what I'm talking about.

> Every OS Google has is open-source - Chrome OS, and Android. Yes, we know they do have services that aren't, and some that require payment, but you can use, fork, and hack on Android or Chromium if you want to.

Read this: http://arstechnica.com/gadgets/2013/10/googles-iron-grip-on-....

I don't know what your argument is, but also consider that apple has an opensource core to their OS too - http://en.wikipedia.org/wiki/Darwin_(operating_system). But they have a closed source shell on top of that? So does android.

> Google is better than Apple or MS.

This is what i'm talking about when I say illogical apple hatred. Google is not better than Apple or MS.

> It's not about the app store. It's about restrictions on side-loading your own app onto a device you own

If people could sideload anything on their devices, it would break trust in the platform. Apple want a platform that people trust, and most people want that too. It's not fundamentally wrong to be different, but just understand that you're a minority on this planet and that people who don't want to sideload apps are the majority.

The Kinesis classic is the keyboard that saved my career.

My wrist pain actually increased slightly when I first got it, due to the strain of having to interrupt my years-old muscle memory. It took several days for the thumb keys to become (somewhat) automatic. Within a couple of weeks, I was on my way to pain-free computing. It's now been over a decade, and I consider the Kinesis keyboard to be the primary factor in my recovery.

Is there any doubt the judge was paid off? No sane person could make an argument that a serial criminal, a serial killer, should not face consequences for his actions because he didn't face any in the past.
Please don't misunderstand, I'm not excusing his behavior. He's not a sociopath because she shows remorse and cares about the people around him. The guy wasn't making excuses for himself. He's not operating on some righteous framework, which Garfield's question implies. He's not saying he's doing it because he thinks it's the right thing to do. He knew what he was doing was wrong and he feels bad about it, but he was simply enjoying it too much to stop.

If I steal a candy bar and you ask me why I did it and I said "Well I felt bad, but it looked tasty and I really wanted it". Asking me then if it's okay for other people to steal stuff from me is a dumb question to ask. The only goal of the question it to try to shame me. The awkward silence was awkward b/c Garfield asked a dumb question. It was trying to shame the guy and show some hypocrisy. But there is no hypocrisy. He's fucking people over, and making himself rich. The guy already knows he's mistreating others.
I adore the topre keys and small footprint of my HHKB.
We will have to start voting for people who will end it, instead of promising us free stuff (which often as not, is a lie too).

Can someone please write a TL;DR for me? I sense that this is an important issue but my eyes seem to glaze over trying to figure out what's really going on here. The accusation is that AT&T is lobbying to attain a monopoly to share with Comcast, but the gist of the move is quite hazy. Thanks.
No offense taken.

Yes, there isn't a proof that the bridge in question is man-made. I deliberately put it up there. GSI claims it 'may be man-made' but it stops at that. Here is something you might want to look at: Search about 'floating rocks of India' (Pumice rocks) that have specific gravity lower than sea water.

Once you dig deep into some of it, read through Ramayana and also dive into history of Sri Lanka, I am sure you'll find something really interesting. That's why in the parent comment I wished someone undertook the journey to capture and record "everything" that needs to be explored of history over there.
In some respects, NZ still is. With Keyes about to be kicked out of office, watch this space however.
>Dvorak, which I've given up on twice

I learned Dvorak before switching to the Kinesis. I was only able to do it by having some strategic down-time in my job, and I would say it took around a full year before I was even close to my old QWERTY speed. I can now switch between QWERTY (laptop) and DVORAK (desktop) with only an occasional hitch.

Take it from me: the advantage of Dvorak pales in comparison to the advantage of a good keyboard. Add in the fact that the whole world (games, vim, cut/copy/paste) revolves around QWERTY, and Dvorak starts to lose its luster.

(Come to think of it, the biggest plus for me with Dvorak is that I can left-hand mouse and hit copy/paste/undo with my right hand...)

The parent was responding to a quote about successful people, so there would be no reason to look at all college graduates. A significant number of them will not be successful (as measured by income).

As an aside, while trying to find income data by education that excludes outliers (sadly, I failed to find anything) as prompted by your comment, I noticed that college graduates with only a bachelors degree represent roughly 20% of every single income group, except for incomes below $30K, where they only represent ~10%.

I haven't had much time to digest the data, so I am quite possibly overlooking something obvious, but wouldn't you expect that number to rise with incomes if simply having a degree provides an income advantage?

That's exactly backwards. Most games of chance post odds explicitly. Entrepeneurship works because 1 it actually creates value, not negative expected value, 2 much of the gambling is with other people's money (investors and creditors) who don't get their teeth in if the entrepreneur fails, raising EV further.
The cost of developing the Windows 3.1 OS in 1992 was $250 million.*

Clearly, software development was expensive and difficult.

In 1992 could an open-source OS on a shoestring budget contribute something of real value?

*adjusted for inflation: $150 million in 1992 = $250 in 2013.

Hi. Schedule an appointment with your doctor immediately.

I experienced pain in my shoulder, then, eventually, numbness in my left index finger. It was a pinched C6/C7 nerve, and I've been effectively unable to work for four years.

I'm serious. Go see your doctor, then examine your computing habits very closely.

I'm not so convinced on the conspiracy theories here. I say that as I had a similar experience in Auckland airport a couple of years ago, when travelling to another destination in the country.

The guy who interviewed me was actually very polite and friendly. They said I'd probably been flagged up as suspicious due to my itinerary. I'd travelled from China, for a 2 day visit to see a customer, with tickets booked via a US agent (Expedia). Suspect that living in China at the time had quite a bit to do with it.

Got asked all kinds of questions, most of which I didn't know the answer to. Didn't get my laptop searched or asked for any passwords, but they did make a point of asking if I had any porn on my computer. I said no, and they asked no more. They way they asked though did make it sound like it was a bit of an issue to them.

Took almost 2 hours in total. I actually didn't find it particularly stressful, mostly as I still made my next flight. I'd had far worse times travelling to the US, and getting some vindictive border agency guard who's out to get you by any means possible. Really, I loathe US immigration.
Dvorak is nearly pointless. I've been typing in it daily for over a decade, and it has near zero benefit over simply buying a better keyboard and using proper form.
Most monopolies are not natural or at least not entirely so. They are enabled by government regulation. In many areas for example, even if you wanted to and had the funding you would be prohibited from starting up a new cable or telco because of local franchise regulations allowing only one provider of those services.
There's basically a separate system of justice in most countries for anyone with a net worth of 8 figures or more. He literally got away with murder.
It is really pathetic to see how people try to defend their fundamental beliefs without any substance. People are brainwashed to believe that vedic scriptures are full of knowledge (I was a victim too. I used to recite some parts of the scriptures like purusha suktam). In reality, the scriptures are filled with filth like procedures of sacrificial, bestiality and orgy rituals, calls upon gods to slaughter their enemies (who have stolen their herds), etc.

Ambedkar was very diplomatic in his criticisms towards them. Osho was not so kind. See: http://www.osho.com/library/online-library-rigveda-tulsidas-...

You can also see that the site claims that Jyotish is astronomy but it actually means astrology.

Here is the description of Saturn in one of the texts "Parashara Hora Sastra"
http://archive.org/stream/ParasharaHoraSastra/BrihatParashar...

29. [Saturn] has an emaciated and long physique, has tawny
eyes, is windy in temperament, has big teeth, is indolent
and lame and has coarse hair.

What is legit or scientific about it?
Agreed on all parts - for me, I live in DC, in a neighborhood with good cab density, and Uber is in the cab business as well as the swanky car business. I'll launch the app, hail a cab, and by the time I ride down the elevator of my building, there's a cab parked out front waiting for me. It's a reasonable approximation of the future.
The FSF is right; a lot of companies implicitly centralize information behind closed doors. It is damaging to liberty in the long term.

What's missing from the statement is a plan. How can users get services equal to or better than those offered by Google/Facebook/Yahoo/... without centralized "cloud" computing? How are the developers going to support themselves financially?

I love and support the efforts of FSF. Almost all of my scientific work rests upon a GNU footing. But before distributed software can eat the centralized software world, it has to be equal or better. This is no different from global warming; if solar power were cheap and effective, nobody would be burning coal.

Even when code is open-sourced, and alternatives are available (gitlab, anyone?) users still flock to centralized services like github. I do, with repos at github. I served my own mail, read it with mutt, and filtered my own spam in the past on my own server. GMail is way better at all three of those things, and I don't have to burn a couple of man-days/year keeping configuration up to snuff.

The unstoppable advantage of free software is that it's a ratchet. Whenever something good emerges, it never goes away. If someone can duplicate GMail's functionality in free software, it will be with us until email goes the way of sanskrit.
Whenever I read these I always think there is more to the story -- usually I find out later that the "victim" was being a jerk (not that they should hassle jerks -- but that is human nature).

In my current apartment, it's not even possible to get 3rd party DSL. (Reply from DSLExtreme: After looking into your prequalification results we determined that we cannot provide High-Speed Internet Service to your location.) And what's worse is that my apartment isn't wired for cable either (cable guy came out, said "sorry dude").

So what's left? Satellite? Tethering? I wish there was a reasonable alternative, and I would be happy to buy even measly 1.5 Mbps service as long as the money wouldn't be going into AT&T's coffers.
Wow, managing to piss off both ends of the issue (rights holders and video creators) is pretty impressive on YouTube's part.

The problem is that you can't know wether they'll do that until after you gave them power, and after that there is no real recourse (not in practice anyway). That's kind of where the whole thing falls down, and the idea that wanting to get re-elected keeps politicians in line turns out to be naive and simplicistic.

Heck, if I buy a piece of bread and there is a dead mouse in it, I can actually return it and get my money back! So many small transactions have safeguards against fraud or fucking up, but handing over the keys to whole nations? Right this way sir, make yourself at home. Imagine hiring a babysitter, and they just eat your baby, clear your fridge, and the cops force you to pay them for their hours regardless. That's kind of where democracy is at.
Zipcar is great - I love it. But as far as a "self-driving car network" goes, one of the big advantages is that you don't need to worry about parking on either end. A higher percentage of cars are in the process of getting someone from point A to point B rather than taking up space somewhere.
Sees it just works better if you say what you mean and leave off the useless labels that only serve to inflame readers one way or the other.
>>If you’re dependent on YouTube for making money from video content, that’s disastrous, as even a single strike against your YouTube account can limit the account’s functionality within the site and impact anything from the length of videos you’re able to upload to your ability to monetise those videos with advertising.

Always be very careful when your business depends on the free(AFAIK, uploading to youtube is free) services & regulations of some other company. I can't help but think of the stories on Facebook-platform/API dependency. That said, I still think it's bad how Google isn't a bit more careful when considering that, intentional or not, they now hold several people's livelihood in their hands. Semi-arbitrarily dropping sites' page-rank, marking sites as phishing attempts or messing with youtube-accounts' abilities to continue their business by some automation-script is kinda harsh. It's kinda like a guilty-until-proven-innocent thing where you just wake up one day and find your youtube-channel crippled. You're losing money while trying to contact Google and get everything straightened out. The fact that Google isn't exactly known for amazing customer service adds to the problem. I certainly don't expect Google to manually check all that content, but how about instead of immediate penalty... they send an email with a warning that action will be taken in 20 business days if alleged-offending content isn't removed. At least give the uploaders a chance to fix the issue or plan for an "outage" of sorts. Perhaps even for websites & youtube channels that are well known high-traffic & monetizing, Google makes sure to white-list them so they can never be auto-penalized without a human confirming. Instead, it just triggers an alert to all parties involved so people can look at it.
What's really bizarre to me is how a "digital currency" can have such slow transactions. I want my transactions carried out and verified instantly. Right now its minutes to hours. But once the network grows, it could be days.

I'm not sure if this is the first science fiction story to tell of a lone biologist creating a plague, but Frank Herbert's "The White Plague"[1] was written in 1982 and presages a time (in 1996 no less) that a single actor, motivated by personal tragedy, could create and release such a thing.

In a sense though, this notion that technology can give individuals unimaginable power has also been a theme with Robert Heinlein (I think), where he wrote about an easy-to-manufacture superweapon which basically gave anyone the ability to destroy the world. It was also a theme in Kurt Vonnegut's "Cat Cradle" although that's a little bit more of a stretch.

It's true that our destructive capability scales with the amount of energy that we can harness. And it's also true that biological threats are under-perceived. But it seems to be that biology is inherently messy to avoid being too susceptible to annhiliation. That is, yes, it may be possible to create a plague that wipes out 50% of humans - but in the scheme of things, that's not the end of the world. Certainly not the end of humans (not even close!). And it seems that the likelihood of creating such a pathogen is exceedingly small. Indeed, I'd estimate that you couldn't kill more than 10% of people with a single plague.

But since we're talking about catastrophe, it's interesting to wonder about whether a single human could end the world, and if so how. The most likely way (and rather dramatic way) would be to maneuver a large asteroid to impact the Earth. Energetically, it's entirely possible to do. As for nuclear war, I'm not entirely convinced that would really be the end for humans - although it's certainly possible. Another way to end the world might be to release mega-tons of CFCs into the upper atmosphere, intentionally destroying the ozone layer. I can't think of any other scenarios!
