in that case the hardware total needed at least equals my yearly income. (if not more)

And yes, another 30% do matter.

you also missed the fact that nobody cares. programmers are more
expensive than hardware.

And that's the reality. and it started being the reality in the early 90's I guess.
The purist in me agrees with dothebart but I've long ago given up giving a shit. Now I write really shitty java, because the equipment is so fucking fast it doesn't mtter if I use a String or a StringBuffer.
C is not dead though. For the web thereis no point but I went on an interview years ago for a job on the formula 1 team at UBS and they wanted somebody like me who if need be could count cycles because they did their implementation in java and no matter how much hardware you throw at it, one transaction just took too long.
so in that case (finance) the programmer can do something no amount of money on hardware can.

depends on the number of users you're trying to address. at some
scale it does matter if you need the double number of computing

To this end I like to point out that google isn't written in java.

A lot of their stuff is. Maybe not their main search engine... but they've been quitely contributing a lot of summer of code projects to the java open source realm.

Java is the lingua franca of business logic, and there are benefits to be derived from that.

Summer of code isn't really what I'd call google though, they fund it,
but it's students that are contributing code, not google. Summer of
code has projects in plenty of languages googles likely never even heard
of :P.

Speaking of which, I really need to find a project and apply soon, but
I've been busy with school, I really somewhat wish their application
process didn't fall in the busy period right after spring break.

Java is the new COBOL?

That is, in fact, what I was originally going to write, but when I Googled that phrase it turned out that most people saying so were using it as an insult to the language.

... and a number of their own (non-summer-of-code) projects as well. Google Collections. Etc.

What Java really need is a better memory model: the thing that slows java down is memory allocation, NOT the JVM these days. C# gets it right, sadly.

...the garbage collection once more ;P

 

Maybe some of you have heard of ccmalloc? (a code.google.com projet ;-) Its replacing the default alloc/free to be more thread aware. Gives huge boosts in some cases.

btw, is there a useable database written in java or c-carpet around?

Not that one... last I checked, wasn't it JNI based? And besides just being a record manager with transaction support.

Yes, there are several. I'm using HyperSQL DB aka HSQL mostly for development/test purposes (still deploying to Oracle.) There are many others. Cloudbase/Derby being among the most prominent. I believe Derby was renamed and folded into JDK 6.0. (Continuing the tradition of bloat, I'm proud to say.)

And exactly what is wrong with a record manager with transaction support?


My friend at bloomberg who owns the development of their database one day said soemthing to me, that I've been saying for years that nobody had ever said to me before: there's something wrong with using a language like SQL to get the database to get you the information you want. He put it better, but that was the basic idea.
We were both trying not very hard to figure out what The Right Thing would be, and we didn't come up with anything, so, so far, my best answer is a record manager with transaction support, and put all the precompiled queries IN YOUR CODE.

As we discussed last week, "NoSQL" is the latest Silicon Valley trend.

Yea, thats why everybody uses fancy frameworks to abstract SQL (regardless which language he uses)

Yeah, we could all just store ASN.1 BER blobs in a record manager. Why didn't I think of that? ;)

down-translating everything to ASCII and wrapping several layers of escaping around it seems to be a clear advance then!

there rather should be something like a corba interface to it instead, so you can query it using the commandline but can also work fast with it.

without all that wrap in/ out back and forth!

Get rid of those pesky indexes too; they just consume disk space.

Might as well get rid of all those pesky rows of data too. The database has no data, it just *is*.

We ought to be using aether for holding the data anyway.
