There are Soyuz constantly docked to the ISS with enough seats for everyone on board. Those are where you would exit the station in case of emergency. The signs show the way.

I assume that’s the case, since that is the only explanation that does make sense given the design – with the red stripes – and the consistent placement of the signs. The station has two other obvious exits – the two air locks – but those wouldn’t be used in case of an emergency and don’t need signage throughout the station showing you the way there.

There is an exit sign right next to the US airlock, but that could also just be there to tell you to turn left when you exit the airlock to get to the docked Soyuz: http://imgur.com/8UJP11Y

If you look around you can see that the red stripe design is used throughout the station to show you where things are you would need in an emergency, like “Portable Breathing Apparatus”, “Fire Extinguisher” and “Fire Port” (all for use during fires). There are also some signs with red stripes that have different directional arrows and pictograms on them. Oh, I just zoomed in on those and look what I found: http://imgur.com/3Qyl3bE

That’s your definite answer! The pictograms are an elaboration on the Exit signs, showing you the directions in which you can find the Shuttle and Soyuz. Obviously, that Shuttle pictogram – it was always docked at the other end of the station – is kinda outdated by now. They can hopefully put some nice Dragon/CST-100 stickers on there soon.

It seems they use red/white stripes to indicate emergency routes and equipment and yellow/black stripes for warnings and caution signs. Blue signs to show you where up and own, backward and forward, left and right is. As the station is always in free fall that’s obviously arbitrary, but consistently defining those directions in some way obviously also helps with orientation (and, I would assume, communication between everyone working up there and those on the ground communicating with the station). Look for the OVHD, FWD, AFT, DECK and so on signs around the hatches. Also, look at the hatch where you enter the Russian sector (directly beyond that and down are the Soyuz). You can see many round glow-in-dark patches around the hatch, obviously also used to show you the way to a Soyuz ship, especially if, say, power and lights are out.

By the way, look what I found: http://imgur.com/Elwl8Rf

It seems someone moved the equipment for some reason and patched over the emergency sign, adding a handwritten note with the place the equipment was moved to.

I know that they do have a printer on board but, eh, I guess a handwritten note will do. (I love looking at all of those all over the station.)

(Cosmonauts in the Russian part of the station apparently have an innate sense of direction in space and as such do not need signs, or at least not as many. And definitely none with such gaudy designs!)
I wonder why the author says that Gamow made the great leap backwards, when Gamow was in fact developing a theory first proposed by Georges Lemaitre a decade earlier than what the author states for Gamow.
Short answer: no, but it is extremely unpredictable (hence the billions of people between the low and high forecasts). You can look at countries as incomes increase, infant mortality decreases etc, and see patterns in fertility. And fertility rates do sometimes increase or decrease for poorly understood reasons, but they're not random: https://www.google.com/publicdata/explore?ds=d5bncppjof8f9_&....
I'm not sure what political angles the economist has played to historically, but I find it fascinating how the death of paid-for content is spurring a decline in the quality and scope of news across the board - especially at once-respectable establishments.

When your revenue is driven by ads, which are driven by views, you are incentivized to publish inflammatory articles that play to mass-approved tropes, such as "burn the 1%" and "the police are all evil/out of control". Not to say that these pieces are unmerited, but I've observed their quantity and quality to be moving in opposite directions.

I think Bloomberg Businessweek is killing it right now. They've onboarded some of the best talent (Paul Ford, Matt Levine) and revamped the style of their publication to appeal to the young, ADD, super-exuberant tech/finance crowd (myself included). I believe they are heavily subsidized by Bloomberg's other business ventures, so this seems to be a more viable way to fund and disseminate high quality content.
Ask HN: Which hand written diagram software do you use?
I'm currently trying to make graphical explanations on how a software works and would like to make it look good. 6-8 months ago, I discovered an online app that was making it easy to create diagrams with a "hand written feel". However, I can't find it anymore.

Is anyone here using that kind of software? If not hand-written, what tool do you use to create graphical explanations, if any?

I keep a pretty long bash history, but I don't have it unified among machines or anything.

Others have mentioned several handy tweaks for doing this, but I didn't see all of the ones I use so I thought I'd share them here. One of the important bits is the HISTIGNORE. I am interested in commands that I might want to search for and run again one day, so I filter out commands I consider to be clutter.

# Configure my history preferences
# Load history substitute into readline rather than immediately executing
shopt -s histverify histreedit

# don't put duplicate lines or lines with leading spaces in the history. See bash(1) for more options

The headline is misleading; the article is talking about research that shows we're sleeping as much as we used to, the "myth" being that we're sleeping less than we used to. We still might not be getting enough sleep, it's just now it seems that might have always been the case.

I think a lot of it was for performance concerns. For math-heavy operations, the dealing with lots of objects caused quite a bit of garbage collection overhead. This is much less important now—they've optimized garbage collection to the point that it is often irrelevant—but it's still a concern in math-heavy applications.

Here's an article that goes into it in more detail:

Thank you so much for taking time and writing this. I haven't really concentrated much on the UX front :(, intentionally.

2) The thought process behind 3 days was job-seeker could take a 3 day off from his current workplace and try the new work. 1 or 2 days would be short, and anything more than 3 days is not feasible from the job-seekers side.

4 & 5) Trial would be provided or requested using your social/public profile i.e twitter and a personal link (could be linkedin or resume or website). So asking for twitter and personal link. Email would be needed in the case of a match between potential employer and employee, I'm sending an introduction on email to both.

6) Yeah I'll need to work on that and clarify stuff.

Edit:

1) Trial could be decided between you and the employer over email, could be remote, or physically move to the office.

2) Once any job-seeker says start trial to a posting, it will be shown to the employer. Using the public profile and the personal link provided employers shortlist candidates. When they too show an interest, email introduction is done.

3) This could as well be discussed over the email after the introduction is made. But I might have to clarify this.
Thanks so much for creating autojump! autojump + Crl+R are saving me so much time that would be lost searching around.

There is just this impedance mismatch between our brains hazy recollection of things and the exactness that is required by computers. I find that fuzzy search combined with stats like most-commonly-used bridge this quite well!
> The author hints at the political problem of adopting a land tax near the end: But there are practical problems with a land tax — perhaps the largest of which is that by its very nature it hits the well-connected rich hardest. So we may very well never see this regulation brought up or passed given the current, money-greased machinations of the political machine.

That isn't the actual problem. Its the problem the author imagines.

The real problem with land [and property taxes] is the fact it tends to flow into the cost of rent and homeownership. Everyone in this country is impacted, it is just a question of degree. Similarly, the vast majority sees an item in their basket of purchases goes up by $X and gets angry.

Case in point: The gasoline tax. The vast majority of economists thinks it should go up to cover infrastructure but there is no political will to do so precisely because of how angry it makes their constituents.

People are far less rational than you think they are and if their entire tax burden was shifted into the rent for their house, they'd flip the fuck out.

"A lot of people are pissed because they didn't get in and feel it's google's fault for having a 'broken interview process'."

I agree with much of what you said, though I don't agree with this particular sentence. I'm always pause a little when someone supplies an unflattering ulterior reason for a criticism ("oh, they're just pissed that they didn't get in"), since there may in fact be reasonable criticisms of google's interviewing process that shouldn't be dismissed so casually.

However, as someone who went through it recently (software engineer position, didn't get an offer), I agree with you that it is straightforward, no gotchas or gimmicks. I'd say that at least in my case, if you review data structures and algorithms, and are prepared to use them creatively to answer middle-to-difficult style questions from "cracking the coding interview" (not the exact questions, of course, but at that level of difficulty), at a whiteboard, in 45 minutes, without too much help, then yes, you're prepped. I'm not saying you'll pass the exams, I'm just saying you won't be surprised (again, just in my own experience, for a SE position).

The only thing I was "surprised" with is just how much progress you really are expected to make on these problems and the level of accuracy you are expected to show in your coding. I gave myself three weeks to prepare. I should have taken 3 months, maybe more. No, every parenthesis or semicolon doesn't need to be placed correctly, but (again, my impression here) you pretty much do need to be writing code (probably in Java or C++) that will compile and run with minor edits, and you need to largely solve the problem, at a whiteboard, in 45 minutes. If you get stumped a bit and need a prompt, I don't think that'll rule you out, but if you need too much help getting through, my guess (based on limited experience) is that this will be a no-hire.

Fair enough. I think there's room for reasonable disagreement about whether this sort of thing produces too high a "false negative" rate, but I suppose that's up to Google. Good software developers are hard to find, and while false negatives do cost you, false positives cost you too. I'd generally say this is google's business, they can afford to be picky, as you said.

With one difference… which is that Silicon valley companies almost uniformly insist that there is a severe shortage of software engineers, yet at the same time insist on being (this may just be my own opinion), extremely picky about who they hire. Should an industry that by its own admission tolerates an exceptionally high false negative rate be taken seriously when it says it has trouble attracting enough talent?

The IPv4 address is independent of any one server. Think of it kind of like L2 / L3, when a packet gets to its final network the L3 address is translated to a L2 address (ARP typically with ethernet / IP) with the L3 frame wrapped by a L2 frame. So think of this more like L2 is now a combination of classic L2 and the lower end of L3. It's sort of halfway between home router style NAT and switching; and yes, I'm sure it runs as close to full speed as switching does. This kind of set up is very common in cloud based services that support live migration (not that this service does; it's bare metal).
There do exist other alternatives.
Bribery in the US is definitely NOT a day to day occurrance.

That being said, the US is definitely corrupt, but in the US corruption is legal as long as you follow the corruption rules. For example, I can donate $100K to my favourite political candidate right now and then ask them for favours, totally legal, but yet corrupt.

We're coming up to election season and candidates have already started bragging about who is paying their way (e.g. Wall Street, Koch Brothers, Big Oil, etc) and if anyone doesn't think this type of thing is an investment into future political favours then they're very naive.

PS - While there is corruption in every country, the US's electoral finance rules make it particularly bad.
this is cool.

Anyone else get sense the desperation in this?

Once upon a time every middle-class home had to have a piano. Now they are relics. Sales of home pianos have tanked. Steinway sells to the pros, a small market, and the very rich. But those very rich who were raised with pianos in every home are getting older. Their kids don't want to spend $$$,$$$ on a great piano and the maintenance it requires. So Steinway is injecting technology in hopes of keeping the rich onside.

Pianos, the good ones, last for decades. But what will this ipod-dependant thing look like in 2030 or 2060? Will they join their brethren in concert halls, or lie forgotten in grandma's storage locker? An old Steinway is a useful device capable of doing the same job today as it did when built. An network-enabled ipad accessory will not age so well.
I thought this was good:

> OT, but do anyone know exactly what went wrong with McAfee after the founder left the company?

> It grew, it got big, like every company. When I started, there were 4 of us. Generating $10M/yr, we could have lived happily for our lives on that. VCs came and offered to make it bigger, we had to grow, we didn't have sales, marketing, etc. I gave it away, unless you were a government, corporation, etc. Once I went public, I had 1000 bosses, investors, FTC, SEC, all my time in meetings and interviews. I hired a programmer/day for over a year! I used to spend time taking apart viruses, not I was an accountant. Once a company gets big, it becomes slow, and cannot survive in its current form.

Hi guys,

I built getlostinside.com a simple travel guide that shows you what you can do in your vicinity. The idea is that instead of listing existing places, the site shows you what you can do for a given budget (e.g Enjoy the view from the highest mountain in Berlin for 0€). I also want it to be 100% user curated. It’s currently limited to Berlin, so i’m looking for feedback from travel experts on this project. My idea is not to create the next tripadvisor, instead i want to partner with travel blogs to have a smaller expert curated selection of things to do. What do you guys think?
If we could get a "picture" of the CNB in all directions, it could give us hints to the structure of the Universe at two seconds after the big bang, just as the CMB gives us hints to the structure of the universe at 379,000 years after the big bang.
Not sure what is worse: that MS has Powerpoint interpreting randomly pasted XML, or that they do not have handling for excessive memory usage beyond crashing the whole program.

That's interesting. I wonder if that recruiter needs to work on his filing system a bit -- e.g., work on stuff in the inbox, then place it in the outbox :)

I wonder what the most politic way to deal with this situation would be. It sounds like you were polite but honest, which is a good thing in my book. I might have done the same, but perhaps it would have been better to just play along, score higher, and get pushed to the next step? Just speculating!
>So first of all this is not "a secret" at all and you don't need to be "special" to do it. And of course you don't get targeted personally but they do an automated/anonymous match on your search history.

Yeah, and there were no magical unicorns involved, what a dissapointment.

That said, I think all these premises are wrong.

Clearly this was indeed a secret. It wasn't publicly announced to be happening, only appeared to selected individuals.

Second, you do need to be special. Special doesn't mean to have some mutated X gene, just that it doesn't apply to everybody, but only those matching specific criteria. In this case you have to have the skills to be able to trigger the process (with matching query results) and then complete the puzzles. That would leave 99.99 of the population out.

As for the fact that "you don't get targeted personally but they do an automated/anonymous match on your search history", in the end you do get targeted personally (if you succeed), and obviously even people who get targeted personally "from the start" are first targeted by automated matches between tons of candidates. I don't think some recruiter just pops up a name out of the blue because they personally know them.
(Wow, even an attempt to engage by asking a question gets downvoted by HN's pro-Google brigade...)

Anyway, assuming you believe Google effectively has a monopoly (as the EU commission does), this is yet another example where Google abuses that position to favour itself over everyone else trying to recruit. Very similar to the way Google manipulates shopping results (but sneakier).

I'm not even saying I agree with that logic, but it will almost certainly be added to the things various regulatory bodies will investigate. Apparently it's already taboo to even mention that on HN.
A new kind of lossless transmission line, perhaps? That would be a big deal if so. Such a line would also be immune to the effects of space weather, since the field along the tunnel does not interact with any exterior field.

I think this community has a particular eye for injustice and depravity of accepted norms.
As a fellow American citizen, I think their concerns are reasonable. This varies a great deal by city, and one's experience of police can vary a great deal by the extent they decide you look suspicious. Factors there include race, gender, and all sorts of subtle appearance cues that can be mysterious to foreigners.

A sysadmin pal, for example, was walking down the street in a major city dressed in our standard sysadmin shabby with his beloved but somewhat ragged hometown baseball cap. Some cop decided that he looked to be a guy who had just shot a cop. They eventually sorted out the mistake, but my pal needed treatment in a hospital afterward. To this day he can't stand cops.

And that's in a city where I think the police are generally chill. When I lived in Chicago, I learned to treat cops with the deference I'd give to a vigorous, ill-tempered horse. The may have thought I was treating them with respect, but in my case it was a distrust born of observing how they treated other residents.

It's too bad they don't allow regular candidates this path of bypassing their atrocious phone interviews that ask you to write code in Word (lately) while someone sits huffing and puffing on the other wait impatiently. That's of course, if they even manage to call at the right time. Sorry, but the only impressive thing here is Google's continuing stupidity in this area (not that they're alone).

I'm not so sure this is accurate. Speaking entirely anecdotally here, as I haven't done a lot of research on sleep trends. But ever since I saw Inception, I got into lucid dreaming. I only got lucid a handful of times over the years, but in trying to do so I changed my sleeping habits. I get about six hours of sleep every day, but I'm at a point where I fall into REM the minute I'm out. It's supposed to take an hour to fall into the cycle, but I've had cat naps that last about fifteen minutes with a full on dream. Since REM is the part of the cycle where your body rests the most, I feel that if I fall into the cycle sooner rather than later, I can safely shave a few hours off my sleeping time. Just my $.02
