When working on console games I've always found it useful to have one screen (in this case, a TV) dedicated to your program, and 2 left for use with your PC. When working on PC stuff I've also used a similar setup with a second PC as well (with its own keyboard and mouse, no Synergy/KVM/etc.). So I was expecting having 3 plugged into a single PC to be just as useful! But I had the same experience as you. I used it for about two weeks before I had to admit that the extra monitor was just one too many.

I do wonder if it's just the aspect ratio of the desktop area though. I feel like if I had two landscape monitors on top of one another, and one portrait to the side, that would be more manageable.

(The horizontal arrangement of monitors is more common, but actually I think the vertical one is much better. I currently have my laptop sat under my main monitor, and it works very well. With a horizontal arrangement I've always found myself ending up with a preferred monitor straight ahead and spare less-used one(s) to this side. After all, who wants to keep having to turn their neck? But with them stacked on top of one another, all you need do is glance up and down, and they're all equally useful.)
The anti-immigrant crowd is gonna hate that one ... even more if they can figure out which bus it's on.
No one seems to realize how hard it is to immigrate to the United States. If you don't have a close relative (parent, sibling, or child) and are not fleeing persecution, it is quite incredibly hard to immigrate to the United States.

The pathway to a green card (permanent residency), for nearly everyone else (i.e. skilled immigrants) involves getting an H-1B or L-1 first, and then asking their employer to sponsor them for permanent residency.

So when I hear anti-H1B rants, what I'm hearing is hatred towards immigrants and immigration in general, that seem to be coming from people who have forgotten their own heritage.
Great example. Thanks.

Why is this a bad thing? You decided to download and to play the game. You put yourself under the "game" rules. You are an adult, not a child.

>Even worse is when they later convince themselves that the money was well spent (say, for an extra life in Candy Crush).

This is a highly subjective claim to make it pass as an argument. I may personally agree that every money spent on games is money not well spent but that is just my opinion.

Users are not babies. As long as no gun is pointing at them (i.e. the game gives you any content for free but also offers you more if you pay ), every purchase they do is legitimate.

Maybe I'm losing the point of this whole debate, I don't understand what you think users need protection against.
Bluetooth is a short range encrypted point to point link. It would be considered part of the station. Repeaters, in radio jargon, generally accept input from many sources, often without access control.

I don't think that's the case at all. I think its workers who have seen the job situation get progressively worse in the US over the last few decades, and are trying all avenues to prevent it from getting worse (in this case, depressed wages).

If workers had more protections (as it is in other developed/first world countries, for example), I don't think you'd see such a strong backlash against H-1B visas.
Resisting the urge to put "operating system" in quotes :-)

This kind of nonsense would not have been possible on *nix, OS/2 or VMS back in the early 90s. (written as somebody who had to write a fair amount of C code back then for such things in addition to the scourge of Win16)

Wow, that's what "The Economist" titled that article, but the article has exactly zero substance devoted to how that missile system works. There's a description, and an "87% success rate" quote, which sounds made up.

Theodore Postol does a better job, frankly, and all he's looking at is contrails. This article is a disgrace to The Economist's good name. Retract instantly, is my advice.
No idea about first world countries, but in Russia there are broadband ISPs who throttle or completely drop P2P traffic for various reasons. Don't know about VoIP, though - the only cases for blocking those I've read about are corporate networks with their inhumane firewalling.

I can't say throttling/blocking is completely universally bad - for example, we (I work for an ISP, too) had to drop uTP traffic when uTorrent just rolled that protocol, because due to high-PPS low-size packets it put quite a heavy strain on routers, so everyone had worsened network experience. Even though that was somehow controversial decision I still think that that blocking brought more good than evil (we didn't block classic BitTorrent protocol by any means, just uTP) so there should be some rare and sane exceptions from Net Neutrality rules, but nonetheless... the point is, that happens on broadband, too. Just less often.

The H-1B is explicitly temporary. It might be a way to get your feet on the ground here, but it simply is not intended to be part of a path to citizenship.

This isn't a zero sum game for you and the H-1B visa holders. The H-1B and other skilled labor visas select for individuals who are intelligent, mobile, and entrepreneurial.

Those individuals and their families are here temporarily unless they can secure a green card (a tremendously difficult process that requires limiting their employment choices, handicapping them in their earning potential compared to you). Most Americans expressing your sentiment have no idea how much hassle immigrants have to go through in this process or every time they cross the border.

Historically, the United States has relied on this enrichment process to invigorate its economy with not just cheap migrant labor, but cheap entrepreneurial, technological, and scientific expertise. Many countries have suffered severe brain drain at the hands of the US precisely because of H-1B and other immigration policies. The US owes its technological and scientific leadership in many, many sectors to these skilled immigrants, who had to come here to get the environment they could thrive in. Their potential would have been wasted elsewhere.

Look around you. Many of the companies that constitute your labor market are built by people who took a chance and risked everything to move to the States, or people who moved here as their children. They helped the technology industry and the US as a whole to innovate its way out of the anti-utopia you describe, and will continue to play a key role in our worldwide technological leadership. They deserve to be here.
This is some crazy-ass shit.

I didn't catch the entire interview, but I caught this... "expert comment", I guess I should call it, on PBS's "News Hour" yesterday. Heavily paraphrased:

The ceiling of the exclusion zone was 32,000 feet. The plane was flying at 33,000 feet. Pilots like to maintain significant buffers. As a pilot, I would be very uncomfortable with 1000 feet of buffer. If an incident occurs that requires manoeuvring, e.g. a mechanical incident, 1000 feet is very little room.

P.S. I'm not speaking to the accuracy of the numbers cited. They are what I heard the person say.
"Behind" means "before," depending on whom you are speaking to. Relative-time prepositions in English are pretty badly messed up.
There are an enormous variety of STEM degrees, particularly the "science" part, that have little economic value relative to the number of people with degrees produced e.g. marine biology. In many of these STEM fields the expected wage is essentially lower middle class because the supply of graduates greatly outstrips jobs.

Not everyone with a STEM degree is a computer scientist or an engineer. If you are one of the countless thousands of people with a low-value science degree then not only are there few jobs at any pay scale but you will likely make more money doing something else in any case.

I've been here long enough to see this argument before, yes.

I feel the same as I do now: that if it looks like people are using the downvote as an "I disagree" or "I don't like you" button, people are entitled to call this out and ask for an explanation. If no good explanation is forthcoming, this suggests the downvoters might be in error.

The SA-11 'Buk' TELAR (9A310M1) was indeed designed to be used as part of a broader system including C&C, dedicated launchers, and the 9S18M1 radar. It certainly requires trained personnel to operate.

With that said, the Buk was also designed to surpass its predecessor('Kub') by incorporating a fire control radar into each launcher (TELAR vs TEL), so that it could operate with some autonomy. The original idea was to allow the whole SAM network to track multiple targets independent of the 9S18M1 radar, which would focus on detection and delegation.

This capability also enables an autonomous TELAR unit (as the various images and videos are showing) to target an aircraft at a range of 3-32km, much as people are hypothesizing happened to MH17. It is plausible, although far from certain.

See my comments below. The only error is that the OP reversed the symbol for the battery. Look at the breadboard; he/she built it with the power supply correctly installed.

You're probably right about the datasheet for the opto, but that neither clashes with my statement ("most optocouplers") nor invalidates the broader point (Vcesat is ~300mV; the diode is most definitely off).

Aside: I spent several years as the lead engineer on a line of digital isolators (modern replacements for optocouplers: CMOS integrated circuits with much higher speed, better immunity to common-mode transients, and no need to use expensive and generally boutique processes supporting LEDs). Most of the time, opto manufacturers oversell the capabilities of their optos at low voltage, and generally speaking in industrial applications optocouplers are driven much harder than the currents at which forward drop numbers are quoted in datasheets.

Aside #2: bipolar transistors absolutely do operate upside-down! Reverse beta is usually far worse than forward beta, because the collector region tends to be much larger than the emitter and as a result there is substantial carrier recombination.

In fact, when you want to use a bipolar transistor as a low drop switch, and if you don't care how much base current you have to use to do it, running the transistor upside-down tends to result in lower drop and faster operation. There are a few reasons for this, but it boils down to this: the speed of the bipolar transistor as a switch is limited by charge storage in the base when the device is saturated, or more precisely, the amount of time it takes to remove this charge when trying to turn the device off. The base-collector diode behaves differently than the base-emitter diode because of the difference in emitter and collector doping. As a result, when upside-down, the base-collector junction stores much less charge, the lower beta actually means that the charge is removed faster, and the higher forward drop of the base-emitter diode means that reverse Vcesat is lower than the forward Vcesat.

The downside, to which I alluded above, is 10x or more base current to actually drive the transistor. Depending on the quantum efficiency of this phototransistor and its reverse beta, were the OP to use the phototransistor upside-down in this circuit, it might not be able to shunt sufficient current to keep the optoisolator off.
I think the trick is that it's ok if the sequence makes them all the same orientation partway through the sequence.
Surveys consistently find academic economists to average left-wing. I had thought economics degrees were also the highest-paying (at 75k if I remember correctly) but apparently this has been outstripped by a few engineering disciplines, particularly petroleum, in the last few years. I edited my post.

However, having an economics degree is still a good way to make money and academia not a good way to make money. The point is people stereotype research economists as corporate shills or something, when they tend to be left-wing and most research economists consciously gave up money to work in academia.
An Antonov AN-26 was shot down at 21,000ft on July 14. Assuming that the Ukrainians don't shoot down their own military aircraft, it was either shot down by the rebels or, possibly, the Russians. The rebels took credit and there is no real evidence that the Russians did it, AFAIK. Also, the twitter comments by the rebels immediately after MH17 crashed, and the conversation between rebel commanders released by the Ukrainians, speak against direct Russian involvement. (And on top of that, although militaries certainly do make big mistakes from time to time, it is clearly more likely that the poorly trained rebels would have made a huge fuck up like this than that the Russian military would have done so.)

That's not the case in practice. Many H-1B holders apply for permanent resident status (which after 5 years allows citizenship) via the employment-based immigration process (http://immigrationroad.com/green-card/immigration-flowchart-...). There are immigration law firms that specialize in maximizing your chances of success in this process, and many large tech employers have a support mechanism for this.

I meant a pathway to immigrate to the United States. Yes, the H-1B is non-immgirant visa. My point was that if you want to immigrate (i.e. get a green card) based on your skills, the pathway (toward gaining permanent residency) in most cases involves getting an H-1B or L-1 first.

Most of these workers strongly desire to immigrate to the Untied States on a permanent basis, and the truly skilled ones (I'm not talking about ones hired by outsourcing giants) work really hard (and usually get paid really well), and contribute significantly to the company (and as such, to the United States as a whole).

This is the magic if market dynamics. If a business fraudulently takes advantage of this they will not build up a customer base, paypal will shut down their account, and money will be refunded. PayPal is taking most of the risk so that businesses can be flexible and provide a better experience.

Ugh what why??? What a terrible way to conduct things. This was the top voted post on HN today, and there was great discussion happening. In the future, please consider letting good discussions about HN continue, instead of immediately censoring criticisms of the site.
I started writing a long reply to this and realized I was rambling a little bit.

I think there are two key insights. Sometimes if you're really good at what you do, you might get stuck in a local maximum. And the only way to break out of that is to try something completely different. This involves learning completely new things and is a little uncomfortable because it could be really slow going in the beginning.

The second insight is that this slow progress is actually okay. Matt Frazier who has a popular running blog once wrote that most people overestimate the progress they can make in a year and underestimate the progress they can make in a decade.

So that's the perspective I use for a lot of my goals. I'm fine with not becoming an expert in, say, first order theorem provers by the end of year. But I would like to make slow progress towards that goal and achieve it hopefully by the end of decade. And really this is a very very achievable goal and all I need to do to get there is learn just a little bit more each day.

As a side note, I think a lot of people don't even try new things because they realize how much work it is to become good at these things. So just trying, i.e., maintaining a d/dt !=0 gives one a huge advantage over everyone else.

If we were to be pedantic here, Austria was losing badly against Serbia for more then a year. At that time it was clear that Austria did not have a standing chance to win against Serbia in any meaningful way without extensive help from other countries, so the conflict couldn't really be qualified as minor.

The things started to change when German army joined with Austrian forces in attack to Serbia, and Bulgaria decided to step in and stab Serbia from behind, but at this point the conflict was already far from "minor" and "local".

There's far less emphasis on in-house training for specific skills than there once was. My mother, for anecdata, came out of a computer science program in the mid eighties with her education financed by her employer. Companies today don't see employees as long-term investments, and that's one of the prime reasons for the lack of people with the specific skills that those companies need. Highly specific skill sets aren't really encouraged by the academic system, and as a result people with your specific skill set on the job market become a proverbial dropped twenty dollar bill: you'll never find one because someone else has already snapped it up.

Of course, treating workers as long-termers means changing the incentives. The current set of incentives are oriented around cheap perks to lure in new workers, rather than the more expensive measures necessary to keep people around for the long haul, like pay raises to keep salaries industry-competitive or other serious rewards for long term service. (one could imagine a partially paid sabbatical year or something...)

The author seems to have a thing against academia. This confuses me: his work is related to the Choiceless Computation work (which is academic), and though the author never cites it, the same ideas were explored by Sussman and Radul in The Art of the Propagator. Why the hatred of academia? Why the frustration with computer scientists? It's a cool set of ideas, that admittedly is not in the mainstream of PL research. But there's no reason to hate the mainstream for this reason: they are working on cool ideas too, and are making good progress. There's value, yes, in working on things off the beaten track, and there are academics that do just that. If the goal is the advancement of human knowledge, we're all in this together, and author's bile is unnecessary.

The discussion is continuing. You just posted to it.

The HN front page has never consisted of just the most upvoted posts. If it did, HN would be unrecognizable. Whatever you call this policy—people say 'moderation', 'curation', 'censorship', and other things, depending on how they feel about the most recent thing we did—it isn't secret and it isn't new.

I'm happy to debate this with you till the cows come home, but my first duty is to see that the stories on the front page are the most intellectually substantive of the ones currently in play. I'm not seeing that here.

It's pretty simple. Any country which is receiving massive US aid is friends with other countries receiving massive US aid. In some cases the frienship is a sort of "secret" (eg. Saudi Arabia and Israel) or "complicated" because officially, for appearances sake, they should align on religion or something.

Iran used to be part of the USA club when it had the brutal murderous dictator. But now it's enemy to the USA club as soon as they overthrew the dictator.
