While it's interesting that the NSA blocked encryption in TCP, I'm not convinced it would have been a good idea to do it at that level in practice. Encryption has moved on quite a lot since then (at the very least due to Moore's law holdi

Not for that sort of size. Light intensity drops at inverse square of distance, reflected light intensity falls off at up to 1/r^4. I suspect a combination of massive floodlights and long/multiple exposure.

Finding the hit points of secondary rays will still have very bad locality of reference unless I've misunderstood what you're saying.

It's not quite clear to me why rasterising of all things is slow. I realise GPUs have a separate rasterisation unit, but other than that, the ALUs are designed for this type of workload. I haven't experimented with latter-era GPGPU APIs

The rounded triangular blocks of the Vienna International Centre (Vienna UN offices) are a curious architectual solution to this problem. Having been built in the 70s, they're not exactly pretty (and currently being cleared of asbestos), bu

This sounds brilliant, virtual memory is a hardware feature which is currently sorely underused in user space. Unfortunately, most mainstream kernels don't give you deep enough access to the VM subsystem for serious trickery. For example, y

My facial hair is somewhat denser now at 26 than it was when I was 24. No idea how common this is, though.

I smell an opportunity for a "readability" style bookmarklet using a monospaced font and a blinking cursor at the bottom of the screen. F11 gets rid of the browser chrome and you're set.

Of course, extracting the entered PIN is trivial to do with a covertly modified terminal. (skimming) Short of the card being stolen, that shouldn't let anyone access your account, assuming the crypto implementation is sound. Likewise, the

Great stuff, good catch on the syscall! I've been tinkering with C coroutines as well recently but since our critical code runs in kernel space they ended up being more hassle than they're worth. I'm still using them in our (user space) tes

To be honest, that sounds like an accident waiting to happen, for both parties. Who owns the work you produce? Verbal agreements on this are great until push comes to shove. If the company exits, you'll almost certainly get nothing, regardl

WPA(2)-EAP ("WPA enterprise") has supported this for years. It also has other advantages, such as supporting multiple usernames, each with their own password. It also works on most existing client devices (iPhones, etc.) I use it at home; u

Corollary: operate a rogue AP in a bag with the same SSID and password as a public one and get the clients to connect to you instead of the "real" AP. Getting a stronger signal than it should be easy due to closer proximity. OK, it's no lon

My HN "saved" list is about 6000 items long at this stage, which makes it somewhat unwieldy. Are there any 3rd party tools/services for scraping it and allowing searches?

That's pretty unusual in contracted work. The customer would (not without reason) fear that you'd get them to pay for development and then just go ahead and rebrand it as a competing service. I generally try to retain rights on anything but

OK, thanks, will do! First plan of action is to build a small, (more or less) throwaway app that uses all the major bits we're interested in to get a feel for the platform before betting the farm on it.

It sounds like you might only be doing web dev, so I appreciate that you might not have experience with this, but: I've been looking at languages and VMs for doing GUI desktop app work. Specifically, cross-platform apps using native GUIs on

The Java implementation linked from the article, jBCrypt, http://www.mindrot.org/files/jBCrypt/jBCrypt-0.2-doc/ uses java.lang.String's compareTo() function (lexicographical comparison) to validate the hashes of passwords. Is there cause

You can't generalise from that, at least not internationally. I'm a member of the ÖAMTC (one of the road-side assistance non-profits in Austria) and I've had universally good experiences with them. They're very quick to arrive and know exac

Thank you! I wish I could contribute. I'll certainly keep an eye on the content that does turn up as we're getting increasingly restless in Vienna. In addition to the immigration related stuff mentioned in another thread, I'd be much oblige

If an EU founder of an SV-based startup could do a brief write-up of the process they went through (and how much it cost) that would be absolutely fantastic. Anonymous if necessary. I know some travel to the Bay Area for less than 3 months

I'm quite willing to believe it; I just didn't mention it as I have zero exposure to the situation in Asia. I doubt the investment situation will improve until those who succeed aren't (effectively) chased out of the country for one reason

I often search for Cocoa Touch and Cocoa class names to get at Apple's reference docs. XCode has them available offline, but this actually takes much longer than googling, and the doc viewer doesn't seem to support tabs. DDG does fine for

Maybe this is a European problem? I think so. Some Europeans don't like to be thrown into the "Europe" pot ("but we're so diverse!") but it seems we're pretty united on this point of entrepreneurial un-culture. All across the continent, b

I don't know about broadband, but as far as I can tell, you are absolutely getting screwed on mobile phone and internet rates. They're so much cheaper in much of Europe, and probably even more so in Asia. Competition is so fierce that c

Sorry for nit-picking on an otherwise great post, but: It is virtually impossible to understate how much using source control improves software development. Shouldn't that be "overstate"?

I've had this go both ways before, too. I think the point to take away from this sort of experience is that the best you can do is apply your best judgment and re-evaluate as you go along. Often opaque documentation makes sense after you ga

To me it seems that at this stage it's purely a matter of refusing to back down on any "security" measure because that could be interpreted as "letting the terrorists win" by political opponents or voters.
