Question for remote employees: Do you get to join a co-working space as an expensible perk? I am considering asking for it but I was wondering if it is culturally out of the norm for companies to pay for it.
High prices (algo or otherwise) have the side effect of generating at least two surges of news articles - one for the price surge and one for the human intervention to reduce pricing. By now, this must be a well-honed skill.

I think the Dragon 32 really did only have 32KB RAM, but yeah, the full 32KB wasn't typically accessible. Part of it went to video RAM, and part of it went elsewhere, so quite a bit less was available to use by default.

However, there was some hackery you could do to get close to usable 32KB for your program, although I never did that. My tape drive never worked properly, so my programs were naturally very short…

When I graduated to a 286 (in the Pentium era), that was a pretty special moment. It had a 42MB HD!

The tradeoff on a FFT is time vs frequency. So you can have either accurate time data or accurate frequency information. If two notes cross a time window you're going to get the note in between. But if you shrink the time, then you don't get enough frequency resolution. Because pitch is logarithmic (the difference between C1 and D1 is less than 2Hz; C4 and D4 is 32Hz) FFTs really don't work that well for this sort of stuff. Short, low notes in particular are a killer. And the loss of bucket resolution down low makes detection of the fundamental very difficult. The big bump in the wigglegrams that tool provides are not particularly useful for the specific task at hand.
Just curious, why would KA not want to be a complete solution for education?

I can understand the political incentives not to openly state such an ambitious goal - the educational establishment is massively powerful, and doesn't want an upstart replacing them. But is there a reason why, in principle, KA wouldn't want to be a complete solution to all of education?
I think these articles are written mostly so that the scientific community can officially hear about who is up to what- not for the average person out there wondering where we came from. Science is an industry just like any other, more often than not they are financially motivated. They distribute press releases, aim to be cited in other papers, apply for grants, get paid to give talks, work towards launching theories (read: book deals).

As a species, I don't think we're even ready for the answers to any of the scientific and philosophical questions we've been asking since the beginning of time anyway.
Right now, everything is fine on the train system. Go to Town Hall and you'll be fine.
But please control for confunding factors. Supply-vs-demand in SF and London are rather different, costs of living, union membership statistics, and so on. And even after that you are in for a hard case to argue that unions are responsible for this difference.

And, that said, unions have very bad failure modes, as experienced by the problems with regards to (allegedly?) bad teachers. Also, they are able to mask problems for quite some time, and when they finally implode you have a half-broken sector on your hands with cascading effects and unemployment and defaults and ... well, Detroit-like consequences.

Furthermore, software developers have it good, and probably will be in demand for the coming part of the century, but that won't stop labor exploitation even in the tech sector for specific regions.
Here's a hint. Write a Windows 3.1 program in C (don't worry, it runs fine in windows 8). In those programs the event loop is extremely visible, and you'll understand how everything works even in modern languages.

Effectively, even things like Android and IOS still use the same basic principle, and if you dig deep enough this is exactly the structure you'll see.

Plus cooperatively multitasked servers wipe the floor with almost any other kind. It's good to know how they are structured at a very low level and be able to write code to cooperate with them.
When I worked remotely I'd get my work done and with the additional spare time I had, since I didn't have to commute waste time in meetings, I went to as many meetups as I could to make up for the lack of social interaction at work. Working out of a coffee shop or co-working space can also alleviate some loneliness.
You seem to be implying that Uber wants news coverage of it's surge pricing during every humanitarian crisis. To me it sounds like a surefire way for activists to push for laws banning the practice of surge pricing (more normally known as profiteering or price-gouging in a crisis).

I assume they didn't have replacement tiles on board, but assuming they did, I wonder if that would have been possible.

It also occurs to me they could have sent an unmanned cargo carrier to dock with them with the required tiles and tools - maybe a Soyuz... but then, they could have all just gotten into the Soyuz.

There is no mention of the Soyuz in the article. I wonder if they considered that option.

I like AMD. I told the CEO of NetApp he must fire me if going with an AMD processor (Opteron) in the high end (aka most profitable, flag ship) filer turned out to be the wrong decision. That said, I hate AMD, they can't execute for crap.

It wasn't for lack of vision. Fred Weber, their CTO at the time, had solid ideas about moving AMD into the lead for x86 scale chips. AMD kept thinking they were a chip making company and didn't unload what became Global Foundries fast enough. Not to mention that everyone who has to play with x86 is playing with the deck stacked against them. Massive memory machines are coming, all the cool kids are over at HP building one on "the machine" project. AMD could have built that machine 10 years ago, or at least laid the ground work for it. AMD owned a huge chunk of the FLASH market, they could have spun silicon in a way that would allow for mixed FLASH and DRAM on the "north bridge", it would have changed a lot of the economics of things. But when you're constantly about to die, it is really really hard to make strategic moves. So unless AMD stops perceiving itself as being on life support it won't be able to muster the courage to move forward on things where it could make a huge difference. And its not clear to me if it has fallen under the power curve or not. Fred took a huge risk when they did the Sledgehammer (aka Opteron) architecture. And I watched how much pain people went through trying not to piss off Intel to use it (including NetApp). And got to see how it totally stomped the living crap out Intel's Netburst designs. (Intel was pushing Itanium as their 64 bit / large memory answer, which also underperformed Opteron machines)

But the reverberations of that triumph were not good, AMD's inability to execute meant they stumbled on the next few bits. They got the jitters, canned Fred, and went for something "safe". Not a good plan for world domination.
> It's your personal choice to play roulette with drugs. They aren't required to live and the ones you are talking about have almost no health benefits (we aren't talking about weed here). Yet, you someone blame the government for forcing a person to make this choice. Complete and utter bullshit.

No matter if you forbid it or not people will want to take drugs. The government can either forbid it and cause the raging war on drugs that claims lives, leads to the development of underground mafia organizations, or choose to regulate it and make profit from it while keeping the prices reasonable and under tight control in terms of quality and supply.

Your tax money going to the war on drugs has been proven to be completely useless so far, so I can see the benefit of the other point of view.

Nice. Actually the Denisovans gene transfer most likely occurred somewhere in South East Asia. It is not thought that the varient actually evolved for improved high altitude adaption in Denisovans, but was just a varient that later provided some selective advantage at altitude.

15MHz is not from the 70s ;-) (at least outside of labs). The IBM PC shipped with a 4.77MHz CPU in the early 80s, the 386 came out in 1986 at 12 MHz, the Mac II was 16MHz in 1987.

I got hooked on programming by the HP65, an early and very expensive programmable calculator (with magnetic data storage!) that a family friend let me play with for an afternoon. Eventually I got my own Sinclair calculator (36 instruction memory!) and programmed it obsessively. If that thing ran at 1MHz I'd be very, very surprised.

Incidentally, around 1983-85 there was a brief explosion of electronic typewriters with small (usually 2-4-line) LCD displays and oversized calculators with qwerty keyboards, a decent amount of memory (16 kB say), and some form of BASIC. They looked interesting, but I don't think I know anyone who bought one (and my friends and I were all programming geeks).

I think you may have replied to the wrong comment, since what you said has nothing at all to do with what I was asking or saying in the comment of mine to which you attached it.
They are not, and as I recall it was one of the criticisms a friend of mine levelled at the report as well. That by sending up a Soyuz, and using both that module and the backup, they could return 6 people to earth. Then a second and Soyuz mission and the Atlantis mission to replace the backup and return excess crew. Leaving Columbia on orbit awaiting some form of repair or scuttling.

Mostly though it re-emphasized how "not routine" going up into space is. Orbital windows not withstanding, you cannot just "decide" to catch the next one and bring up hardware to fly. Something I hope we can get to with Falcon 9 re-use.
A bug nobody has pointed out yet is that star-star-t (sorry, can't figure out this site's markup for escaping stars) dereferences a null pointer. It appears to work because gcc decides to generate the same code for star-star-t as for star-t (which is correct behaviour if star-t is not NULL, and moot if t is NULL). The code should just be star-t there.

Also, sizeof(int star-star) in hnew should be sizeof( int (star)[2] ).

As others have suggested, if mmap is so fast, wouldn't it be expected that write/pwrite would just be mapped (pun intended) to mmap inside the standard library? [Heck for all I know, that might already be the case]

I have had to actually write benchmark tests to show some people I work with that there was no conlusive difference between the two (with our data access patterns). mmap having the disadvantage that it allows you more ways to shoot yourself in the foot (ever seen SIGBUS signals?). Before that they swore up and down how mmap is this magic performance hack that was burried in there for ages and only the elites know about it.

>So based on these, the main motivation for this is probably for the mass savings and efficiency.

They plan to invest all those savings into a single-stage-to-orbit launcher. It's appealing in a similar manner that SpaceX's stage-return strategy, but in a one-spacecraft package. High-mach aircraft will find other uses too besides orbital launchers.

As for saving a 'mere' 15% at launch that can be crucial from a payload perspective in the rocket equation.

>The documentation is inanely bad. I can't explain it.

I'm surprised that the author is saying this as I've experienced exactly the opposite. R completely documents all the arguments and outputs of its functions, and documentation is easy to pull up by function, and this is almost universal both for distribution and community packages. Additionally the documentation often includes vignettes that show full examples.

In contrast, Python documentation is most often documented on long pages that mentions functions, but does not describe arguments or the output. I've found almost no Python documentation to be adequate, outside of some of the core functions. And when it is adequate, it's exceedingly verbose, and lacking in examples, basically the worst of all worlds.
Why will launching a space vehicle never be as routine as commercial air travel?

I think it should be one of the goals of mankind. There is no fundamental law of physics that says we can't make it routine. The author states that they don't think it will be feasible in our lifetime. However the amount of technological advancement that has been made over the past century is astounding. There is no reason to think this would be unfeasible.

Soyuz is mentioned in the CAIB report.

5.2 Other Vehicles (Soyuz, Ariane 4)
There has been some discussion regarding the possibility of sending supplies to Columbia using an expendable launch vehicle – to lengthen the amount of time available to execute a rescue mission. Because of Columbia's 39-degree orbital inclination, an expendable launch from a launch site with a latitude greater than 39 degrees would not be able to reach Columbia. This rules out a Soyuz/Progress launch. There was an Ariane 4 in French Guiana that successfully launched an Intelsat satellite on February 15. The challenge with developing a supply kit, building an appropriate housing and separation system, and reprogramming the Ariane seems very difficult in three weeks, although this option is still in work.

Any idea why they can't use hydrogen and oxygen directly? Or are they just using a smaller quantity of helium as a 'working refrigerant'?
Cheap rubbish removal Sydney
Seagate tried to take advantage of the 80/20 rule with their SSHD "hybrid drives". Unfortunately, they decided to use only 8GB of flash on all of their SSHDs. That's a far cry from 80/20. The solid-state cache only covers 1.6% of a 500GB hybrid drive, 0.8% of a 1TB drive, and 0.2% of a 4TB drive (yes, Seagate makes 4TB SSHDs). Those Seagate drives don't even have enough flash to hold a recent version of Windows and some commonly used apps, not to mention any games.

The laptop version is even worse because the non-flash part only spins at 5400rpm. Somehow they thought this would be okay in a performance-oriented drive. The slow platters make Seagate SSHDs even slower in general than regular 7200rpm laptop drives from WD and Hitachi/HGST. The only improvement is slightly shorter boot time.

Since the day the first generation of SSHDs came out, reviewers have said that you need at least 32GB of flash in a hybrid drive to see much real-world benefit. Everyone has also been complaining about the choice of 5400rpm. But three SSHD generations later, Seagate still hasn't listened.

Now the SSHD technology is on the way to irrelevance because (1) SSDs have become much cheaper than three years ago, and (2) even if you need a lot of space, the mSATA form factor now allows most laptop users to install an SSD in addition to, not instead of, a 2.5" hard drive. These days, I wouldn't even consider the SSHD as an option. I'd just buy a large hard drive and an mSATA SSD, there's no need for a hybrid anymore.

It's a sad tale of corporate boneheadedness killing off an idea that had so much potential.

When a person says that we should be sending humans into space, they are implicitly claiming to know the ROI, (at least that it is greater than some amount).

I personally don't believe we should be doing human space exploration, because exploration with machines strictly dominates exploration with humans. The only reason for human space travel is if we value moving humans for its own sake (e.g. to reduce the risk of humanity getting wiped out in a comet strike). But I think that could be better handled with anti-comet measures and underground bunkers.

That makes me wonder why Columbia was at 39-degree orbital inclination - making it unable to get to the ISS, and unable to be rescued by a Soyuz.

As a whole, I think the article finally provides a fair amount of specificness, but I was initially struck by how much space is devoted up front to "he-said she-said". It reminded me of celebrity gossip, sportscasting, and punditry.
