For programming type classes (Udacity / Coursera) the assignments and tests are actual programming assignments, not multiple choice. The only Multiple choice questions are during the short lecture segments to try and help keep students engaged and reinforce (in a small way) the topic.
For other course types it is a bit more challenging. I know Coursera was using a peer review system for "Essay" type questions, but I don't have personal experience on how that worked out.
The guys who had ski masks, gas cans, baseball bats, and hammers were clearly prepared to raise hell and break shit up are the ones the police are referring to.
In addition to those, were all the drunk, macho, (proverbial) lemming types who thought it must be a cool thing to do.
Firefox suffers from its constant desire to meet or beat Chrome and the gajillion UI features Google throws into the browser every other day..
The perception is that if they don't keep up, they will lose market share. Maybe you or I don't want them, but all the people who make noise and write reviews and articles compare all these things and pan them if Feature X is not there.
You're damned if you do, and damned if you don't (add features) these days
USB isochronous interfaces guarantee timely delivery. You can also reserve bandwidth so other traffic doesn't affect it. Latency is "bounded" but I don't have figures on what the actual bounds are. (USB 1.1 had 1msec frames and USB 2.0 has microframes at 1/8th of that... so you can get a feel)
Now -- given a crappy device driver and all bets are off.
A shared data structure is considered "lock-free" if its operations don't require mutual exclusion. So if a process is interrupted in the middle of an operation, it will not prevent the other processes from operating on that object.
Technically, there are more formal definitions which state that it guarantees that some process in the system operating on the concurrent object, will make progress in a finite number of steps.
An object is termed "wait-free" if each process will make progress in a finite number of steps.
Wooww... This looks more and more like Oracle version 7 released in the early 90's. Oracle has had 2PC (2 Phase Commit) for about 15 years now. Nice catchup
I think the FAQ needs clarification. They say "Unicode is not properly supported on Windows, and therefore cannot be used.". My impression is that the reality is more like, "PostgreSQL uses UTF-8, and this encoding is not fully supported on Windows the way they would like. Windows (NT, 2000, XP, 2003) does support UTF-16 natively."
What they are doing is layering the opengl icd on top of directx, freezing it at 1.4, disallowing extensions, and NOT providing info to 3rd parties to implement their own icd driver... Net result it will be 50% slower. See http://en.wikipedia.org/wiki/Opengl for details (scroll to "Future in Microsoft Windows").
If true, it sure sounds like they are hobbling Opengl
I agree with you. I have NForce-4 / AMD combo. I couldnt figure out why Pegasus mail kept getting hung up when send mail via SMTP. It turns out that the Checksum Offload advanced feature on the ethernet controller was the culprit!
I had run the Windows 2000 default defragger quite often before this, and most of the actual files were defragmented just fine, but there was tons of green slivers in the display there before I ran Diskeeper, and only a few chunks of solid green afterwards. I got rid of diskeeper because I didn't like it running in the background all the time, but its reboot defrag process was pretty good.
The Windows 2000/XP defragmentor is a limited version of the Diskeeper defragmentor that MS licensed. By definition the limited version does not defrag the MFT or Registry hives. Also, you don't have to run Diskeeper in the background. There is a configuration setting for this! Just run it when you want to defrag
Mysql installs & runs on Windows without any third party software. (Yes, the Web really runs on Linux. I know, I know.) PostGreSQL seems to run on Windows only in emulation (via Cygwin).
This is no longer true! PostgreSQL 8.0 was recently released and one of the main feature enhancements is a Win32 Native Server
I tend to agree. Its one thing to stop providing a service, its another to stop a program feature from working.
In this case, downloading of account data from your bank into your software should not require Intuit's servers or services. It is a cash grab. The question is, what can one do about it?
The ORM layer is a weakness I think, the author is clearly not interested in understanding the relational model and has admitted as such in the mailing list. He commits the The First Great Blunder.
A bit off topic, but the first great blunder that you refer to is not exactly universally accepted as an irrefutable truism. That being the case, this doesnt seem to a major barrier to me. My understanding is that the ORM layer is based on the ActiveRecord pattern which is described by Martin Fowler in his book Patterns of Enterprise Application Architecture.

No, he's John Nagle.

hear, hear... mod the parent up.
You can do design by contract in any language.
Thats akin to saying you can also write any program in assembler, so why use a high level language...
Also, dont forget that Eiffel gives enforcement of class invariants.From the Release notes:
E.1.2. Migration to version 8.1
A dump/restore using pg_dump is required for those wishing to migrate data from any previous release.
Wooww... This looks more and more like Oracle version 7 released in the early 90's. Oracle has had 2PC (2 Phase Commit) for about 15 years now. Nice catchup
So has Firebird... See: http://firebird.sourceforge.net/index.php?op=guide &id=ib6_overview.
It's fixed in the upcoming 8.1 version, now in beta.
Are you sure?
I didnt see it in the release notes... but I did see reference to a fix being held for 8.2. See: http://momjian.postgresql.org/cgi-bin/pgpatches_ho ld
I hope it is not deferred until 8.2... sigh.
OS Support: PostgreSQL ~= MySQL; postgres came a long way, e.g. there's now a stable Windows version.
I just wish they would figure out a way to get a fully functioning Unicode version for Windows. It sounds like they threw the baby out with the bath water. See their FAQ for their detailed description: http://pginstaller.projects.postgresql.org/faq/FAQ _windows.html#2.6

It includes excerpts from some meetings at the recent Siggraph... it doesnt look good for OpenGL under Vista?

"As it turns out, mysql was still an order of magnitude faster on some tests, while mysql and postgres were close on only a few of the tests."

I am not sure about SCGI, but FastCGI can be used for Ruby
In fact, Ruby on Rails seem to suggest using Webrick or mod_ruby for development, but then switching to FastCGI for production (and greater speed)
I cant quite tell if the parent is joking or not, but...
The current release of Ruby is 1.8.2. This (and mod_ruby or fastcgi) is the relevant part from an ISP host perspective.
The current release of the Ruby on Rails framework is 0.9.4.1
