Speaking of a 1-way route, I was really confused about Zynga Poker. I was wondering what the value of the currency was, since poker with nothing on the line is no fun. I was not able to determine that it actually had any, so I quit playin

I did just fine, thank you. Matrix form is not necessary to tell me that we need to approximate both x and dx/dt in order to use our knowledge of d^2x/dt^2. It is not particularly difficult to remember that the second derivative is the firs

I run screaming from courses that cover mathematical background I don't have (e.g., machine learning because of linear algebra) because it's impossible to keep up without having terminology and definitions memorized. Recently got annoyed wi

You also get a ton more registers, 64-bit registers, and other nice processor features.

You can scroll back for a bit in screen. C-a [ (or, apparently, C-a Esc) goes into copy mode, in which you can scroll using the arrow keys. Exit copy mode by wailing on Esc until it gives up. Be careful not to leave a screen sitting in copy

It's much harder to explain impedance concisely. I, for one, never took a circuits class, and I wouldn't expect other CS programs to require one either.

It's correct as written. See sense 9 at http://dictionary.reference.com/browse/shear -- shearing stress is the stress between two blocks pressed together along a plane and moving in opposite directions parallel to that plane. It's a very

The Ice Age and thawing were on a geological time scale. Global warming caused by human pollution, not so much.

Only if technology also makes paying unnecessary. Open WiFi didn't happen because it makes the owner of the access point appear liable; IMO the only way we're going to get around this sort of effect is to build One Big Mesh, which doesn't l

That doesn't work in other applications, like desktop instant messengers.

You caught me while I was monkeying with caching.

Are you shocked that it works or shocked that I would be so stupid as to use SQLite? I expect extremely low load and that I'll have plenty of time to move to memcached and no database... EDIT: it's on memcached now.

by swolchok 17y ago
IMO it should, but right now I use a SQLite database as a permanent cache, so the video will never change. As soon as I get the urge to slack off some more, I'll just plug in Django's memcached support and set the expiration to a day or two

I posted a similar screed about iPhone/Twitter apps that send passwords in the clear or with broken encryption a few days ago: http://scott.wolchok.org/plaintext.html (HN post at http://news.ycombinator.com/item?id=877460 ) Not sure what

Like I said, it's not effective. If malware wants to futz with your browser executable, it's just going to patch the executable, not conveniently go through the plugin interface around which you've designed some forgeable security token.

Ya know, I've never walked into a conference, office or classroom and started counting up the number of men versus women in the room. Did you go to a university with a good CS program that you were in? Were you ever single while attending

Freeblock scheduling ( http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.33.4... ) can do some of this for disks -- on a completely busy drive, additional data can be scavenged for background processes. In anticipation of the likely "

Price, price, price. I'll get excited when I buy a device at fixed cost, pay $30/mo for data, and that's it.

Neither does including anti-Microsoft code in your product. (it doesn't protect against shadier players because those don't care about having friends.)

I would have been surprised until a few months ago. I tried Ubuntu 3-4 years ago and uninstalled it the same day because GNOME was crashing, which I found ridiculous. I've tried it again because it has python2.6 packages and it's OK. Howeve

That's impossible under traditional system configurations. Windows Update can always update whatever "user has confirmed" record Firefox stores, because it has administrative access to the machine.

"Compiled to plain C, hence fast" is not actually a great argument. See e.g. lua-jit, which IIRC just generates subroutine-threaded code. (In other words, it "merely" takes a series of lua opcodes generates C code that is a series of calls

I won't spell it out here because I'd like to make any bad guys out there dig too, but it's not particularly hard to divine my approximate age and where I went to school by Googling.

Doesn't Twisted have a lot of crusty, poorly-documented parts? I remember seeing a lot of old-style classes in Twisted Words.

As far as I know, I was allowed to skip 7th grade math and science simply because my parents asked for it. If I recall correctly, it was a simple request. (I don't know what led up to it exactly, but I didn't miss anything -- those classes
