If you have two sinusoids (say 1 Hz, and 2 Hz) and you want to pick both of these up, then you just need to sample at 4Hz (righ?) to get the whole band from 0-2Hz. You can "filter" each sinusoid out afterwards.
This is probably a too simple version of it, but the concept is the same.
(btw, I'm running 7.2.1-2. I think the previous versions don't do it by default when I tried..)
I would just imaging that the characters are sorted by their unicode sequences, just like ascii characters are sorted by their ascii sequence.
If you are refering to manually sorting the data for speed, my project was pretty simple, so I didn't and don't really know how.

When I installed postgresql 7.2.x, unicode was supported automatically! I use it to store chinese and japanese text in a dictionary type lookup database.
The beauty was that the java code would automatically convert the original Big5/JIS/other encodings to UTF8 first, and then JDBC would store the unicode into postgresql.

A First Course in Database Systems (2nd Edition) - Jeffrey D. Ullman, Jennifer D. Widom
I found that it covers almost everything I needed, with a no-nonsense approach (no "CheckPoints", long pointless blurbs, or long code listings).
Although written for the academic, it didn't stop me from reading mostly the second half of the book first (the SQL stuff), and reading some theory when I wanted to.
The SQL it covers is pretty standard stuff that works with most databases (except for MySQL at the time I read it, some ACID principles couldn't apply). The specific details for each databases can be picked up by reading online docs.

Lain about an AI software girl (Lain) who was created by a researcher (the old white guy with the beard)
The experiment (the program) got stolen (or hacked) by a group called "Knights" who played with Lain.
Near the end, Lain found out that she was in fact a program (as with the girl at the beginning who commited suicide, and the professor dude). Lain is just one of many AI "agents" in the artificial world that "got smart"... (This is why the "knights" are interested in her...)
Once she found out that she is an AI, she becomes a "god", kind of like "the matrix", and she can do wierd shit.
There are wierd parts thrown in to trick you, like Lain's sister. (She got "erased" and "replaced" by a dumb AI because she started to know too much). Also, the fact that people from the outside knew how to get in the Lain world "matrix style".
The key phrase in the series was "The real world and the computer (navi) world" are really the same. This means that Lain's world (you would think "real world") is really the computer world. Also, notice that the artists draw the real real world (non-Lain world) in MUCH more detail than the Lain world.
He's an expert on perl working in NYC, so I doubt he's in a software shop (or even a web shop) like Adobe with his skills. Good perl people are usually in big financial houses (ie with names that contain a Morgan or a Sach) so I doubt boycotting would do any, even a slightest bit of dammage:)
I heard that at the 'Sach' they control all their employees' work (company related or not) like a King! Also, most work done in financial houses use perl heavily since it is a very productive language if one masters it, so they would hire the best, like our unfortunate friend tilly.
I hope tilly gets through this mess, he will be very missed in the perl community, especially on perlmonks.
I've actually been using unicode for quite a while in backend applications, while converting unicode back to regular character sets (Big5,GB..) for the user. Sometimes this involves converting from traditional to simplified chinese in unicode first (easier than the "other" way around, since it is a many to one mapping), and then to GB code.
Actually, Unicode does have different glyphs for the different forms of the same character, for example:
Traditional:
Simplified:
Japanese:
And without Unicode, you wouldn't be able to see all three characters in one page without doing a lot of messy stuff. Also, most chinese can usually read both sets, and many write simplifed on a daily basis (the difference is just like handwriting/printing, with thousands of variations, not just 52 alphabets:)
In the later versions of Unicode (3.x), almost ALL necessary characters are included, including obscure cantonese swear words... If you are concerned about how the fonts are shown based on the different cultures (like missing a dash here and there), you can use a japanese font instead of a chinese font, and just map to it.
The main problem is that Unicode CJK characters usually take 3 bytes while other character sets like Big5 and GB only takes 2. And also, almost all legacy systems, including many business and especially cargo shipping software in south east asia uses their local character set, not Unicode. This will not change for a long time. However, the trend is to use UTF8 in the data storage layer and converting it to the local set (and just replacing a character not in the local character set with a '?') for the user in the display layer.
It appears that Hancom is going after the whole asian market, not just Korea. Versions of this office is being sold in Taiwan with localized chinese. Maybe because they have used the Qt toolkit, as it uses using unicode internally and provides very easy localization support (using the tr() ) function for those who know Qt).
Running on a few megs, this might give MS a run for its money. I'm just wondering how it implements its input methods (Input methods in linux is still far behind Windows).
The chances of this happening by pure chance are about as likely as the chances of you spontaneously morphing with your computer while making love to a goat... really!
I'm not really familiar with software test suites, but the examples on the QMTest page is kind of like testing hardware; an input is given and an output is expected and thus tested. But is this enough for software development?
Is there any way to test other software scenarioes (ie GUI applications like page rengering, user interface, program response, program flow logic)? It seems that the most bugs often arise from an error in the program logic. Does the "real world" test programs other than having many people use the program and filling bug reports?
Usually universities sell their old equipment to clearing houses, where you can get old analog scopes for cheap! (ie, less than fifty bucks CDN)
The old scopes are probably adequate for everything for undergrad EE, unless you do something that requires GHz or requires lots of DSP (like FFT on the fly...)
With most universities replacing oscilliscopes with new (expensive) digital ones, you should be able to get a cheapo old one. If you can't find one, talk to your profs or people who run the labs.
Cantonese would be harder, since people don't usually write what they say, or read out loud exactly what was written (though the trend is breaking down). Phrases tend to be converted to common cantonese phrases when orally presented.
Actually, the other day I was at FutureShop, and they were selling computers that included XP but marked with a "Windows XP with Intel Pentium IV Optimizations". I'm not sure you can just buy a version with the -O2 but I won't be surprised if they will sell an upgrade cd later on that replaces the binaries to P4 optimized ones. Because people will buy them and get ripped off...

Although there's no localization pack for the 'other' east asian language, does anyone know the status of chinese support under OS/X (ie, displaying, rendering fonts, input methods, unicode conversion etc...)?
Windows 2000 and Linux supports se asia l10n pretty well now, though w2k is really good! Everything is stored 'internally' as unicode, and the input/output can be converted to other (popular) encodings such as big5. Even the input methods are fairly complete.
I want to convert to mac for DTP stuff (but requires chinese typesetting for many clients). I tried searching for Chinese support (like truetype fonts, input methods) and the only thing I can find is old 3rd party software for Mac 7.x or something...
Actually the sig is just four Hanzi characters () that make up a traditional chinese compound phrase. You can do that buy typing html "escape sequences" in plain ascii in your documents using '&#' followed by a five digit integer or an 'x' followed by a hex unicode number in ascii.
This convension was defined by the unicode and w3c corsortium (I believe), so if your browser is unicode compliant, then it should render the characters correctly.
The thing I'm wondering is that why don't chinese online newspapers use this convention. I mean, it uses more space but newspapers serve text articles anyways, small compared to images. Plus those Hong Kong newspapers can properly display many extended Big5 characters within unicode common in HK without using their Big5-hkscs standard (btw which only windows supports properly! I can't getting it working for anything else)
That's another issue of course, sorry for the rant.
If you want to understand the communications field, and actually be able to use stuff afterwards, AND be able to crunch higher maths, why not?
If your school has a reputable EE program, it should teach you everything from the lowest level (quantum and semiconductor physics, EM waves) to the highest level (IPv6, TCP/IP, heck.. java sockets!) and everything in between (embedded programming, circuits, signal analysis).
You'll also learn practical stuff to complement it (ie C+asm programming, Xilinx boards for embedded stuff, soldering and circuit simulation, and MATLAB). Of course, you must understand the theory well enough, since the practical stuff will most likely change when you graduate.
Of course, everything you learn will be backed up with higher mathematics that are usually taught to applied mathematicians and physicists, so you can have a nice math knowledge to pursue other jobs if you get bored of EE (like the financial industry!)
Of course, you have to be hardworking, and sacrifice not getting laid much during your years suffering through pages of text. But in the end you'll be well rounded enough able to do anything in the geek industry. I guess what I mean by well rounded is the learning of both practical and theoretical stuff around a particular field, correct me if I am wrong.

I personally see the culture gap between the mainland chinese mindset than the american mindset. Many among the americans actually don't view financial gain as their number one priority in life, however, in the mainland, where generations have suffered far far below the "american" poverty level for decades, or even centries. Making money now become the primary factor in gaining respect or "face" in the increasingly materialistic nation.
Hong Kong, on the other hand, has always been the most materialistic of the three, until recent years where China seems to be surpassing them in terms of finacial dense populations. Money has always been important, and it is needed to follow what is "in" in the popular culture, where Linux and being an "IT" person is so hip. Although there are still many linux using geeks here (like HKLUG, cuhk linux geeks! We put Fast CangJie chinese input method v6 in Linux!!!) the population as a whole follows the latest buzz and fad.
Taiwan has always been a major world player in computer, especially in the hardware side (hey, who do you think wrote all those optimized windows drivers that are closed source?;) and they are considered to be the software giant in se asia, due to their decades of experience in software development. Almost all windows based software that supports chinese are writen in Taiwan. They have a strong culture that is not as material based. Even on the linux scene, they have been the contributors to major i18n efforts, such as Chinese Linux Extensions (CLE), many localizations for desktops. There are many supporters of open source here (gnu, rather than bsd for some reason). Some even set up many/. style sites, like the one above where people talk about politics and open source (minus the first posts...). The goal of these projects is to give chinese hackers a decent environment to operate in, and to give freely to anyone who wishes to use it, instead of microsoft.
I think that even if chinese developers violate these licenses, there is really nothing the west can do. But I just like to point out that not all developers are doing this, and the open source movement in the east is getting stronger, with more people learning to code and learning about open source. Only time will tell us.
