uh, this is really just based around tcpdump, which is standard / available for lots of *nix distributions. Did you even go to the website? It's an artsy fartsy project.
Is NFS secure enough to run over the net as the author described? Would it be better to tunnel it through ssh (is this even possible)? At most he's compromising the server, which I believe he said is at his workplace. I don't mean to speculate, but I assumed that NFS was intended for a "secure" network.
I've got NFS running on my home lan, and it doesn't seem like the type of thing you want to allow open to the net.
Transistors are essentially voltage-controlled capacitors. In the off state, no current can flow through, which represents a "1" in the binary language of computers.
uhh...ever hear of CMOS (which nearly all logic circuits are)? Know what the "C" stands for? Complimentary. So in *any* state one transistor is "off" and the other is "on".
Ignoring tristate elements of course...
Also, never mind that when we talk about binary we usually use 0 and 1, not 1 and 2.
"It's already possible to execute linux/i386 compiled programms. Simple linux-native
applications like 'Hello World!!!' are running now on SkyOS without compiling!"
More importantly, I wonder if they copied a GPL'd version of hello world. hmmmm?
What I want to know is; how does power consumption scale in regards to transistor miniaturization?
it depends, if they're running at higher frequencies the power usage will increase. Plus with smaller transistors they usually pack more on a circuit, so more power is required.
However, the power required to switch a transistor is proportional to the *square* of the voltage, so if you can lower the voltage required you've got a big win. And with smaller feature size (miniaturization) they might lower the operating voltage a bit. So the answer is....it depends.
But still, unless MS it hijacking the POP3 protocol I don't see how they can enforce what client you use.
Perhaps they meant they only *support* those clients? That I could understand. I certainly don't expect Qwest to walk me through expunging just a single message with VM under xemacs. "Now type Meta-M..."
I don't know if that's still the case like it was 5 years ago. The PC has made incredible inroads thanks to companies like Sonic Foundry and similar stuff. I just with their were Unix equivalents of SoundForge, Acid, and Cubase. That'd really make my day.
Of course, their are lots of Macs out there for professional audio. Hell, I still use an Atari for Cubase, and I know some people use an Atari Falcon for Cubase/audio recording.
I have to agree with that, having recently got a dual P-III 800, I would hate to go back to a uniprocessor system. One thing people don't take into account that is that you've got *2* processor caches. Even if another processor has a clock that's twice as fast, with twice the amount of cache, the SMP system will be blazing. Given any multi-process environment (eg, any unix).
Of course, a half gig of memory and two 10k rpm scsi disks don't hurt performance either. My only complaint is no AGP slot, so I've "resorted" to a GeForce2.
while taking a programming languages & compilers class, the prof, after talking about parse trees, mentioned that we could implement double backwords for loops. A buddy and I looked at each and said, "huh? double backwards for loops?" The prof went on to describe a loop where:
for (condition) {
statement1
statement2
statement3
}
the condition is checked, and statement1-3 get executed. Then statement3, 2, 1 get executed followed by the condition being examined. Essentially flow runs down and then *up* the block.
I always thought this was a kinda cool, half baked idea. Useful? No, not really, but cool nonetheless.
And the alternate problem of hooking a laptop up to the home stereo is that most laptops have absolutely *crappy* soundcards. Anyone know a *good* PCMCIA soundcard? It's either that or buy one of these things.
why do you really want this solid state drives? why not just have the OS pre-cache as much disk as it can.
I usually don't hear a peep from the hard drive when I start netscape under linux (though that's after having it started & quit once already -- 12 hours earlier!).
IMHO procedures are often overused. Probably they are required sometimes but only sometimes. If you think you need them than rethink you design. Maybe all logic you are going to implement with them should be implemented in middle layer?
procedures are overused??? Try doing a query that returns thousands of results, where you need to do some quick computations on the results to reduce it to a single value. You want to do this at an application level? Ok, I'll let you. Now what happens when you get 100 clients performing similar queries? All these rows need to get transferred from the database over the (network|socket|whatever) to the application. That's some serious overhead....and possibly some serious CPU: if the data needs to be translated when it leaves the database and translated back at the application, you're just plain killing you throughput (god help you if you're connecting via ODBC).
Put this functionality in the database, keep things local. Sure, not everything should be a procedure but saying "if you think you need them than rethink you(sic) design" is just plain ignorant.
ok, I know that reverse engineering a protocol isn't easy, but why hasn't this happened much sooner? I don't know jack about AOL (or their protocols), but if you can run ethereal or even tcpdump you can start documenting the interface.
I do this quite often, run ethereal before a Windows app connects over the net and bam! you've got a full text of the conversation. I recommend you give it a shot the next time you hit "register via the internet" on some piece of software. You might be surprised what you see.
that sounds similar to vector operations. I don't know where Larry is going with his new syntax, but what really seems like it could extend the language are vector operations. Anyone familiar with Matlab (or similar) knows the power of vector operations.
@a = @b / @c;
now there you've got potential to extend the language.
A stack of 6800's? Do they have eight chips in a cluster to make a 64 bit machine? Perhaps they'll move up to the MC680x0 line soon -- that would show the Macintosh SE who's boss!

it's thing like this that make me want to be a repo man.

Linux comes with an encryption tool for source code: it's called gcc. Run your file through that to encrypt, and objdump --disassemble to decrypt. :)
which is why I don't get that the article says "the technology is months away from commercial applications." huh?
uhh...ever hear of CMOS (which nearly all logic circuits are)? Know what the "C" stands for? Complimentary. So in *any* state one transistor is "off" and the other is "on".

this is great news for people who don't get enough fiber in their diets. It'll help with being more of a "regular" computer user.
I was being facetious, but really for expunging a a single message (under my keybindings) that would be: d M M M N # # #
that is: delete, mark message, next command uses marks, expunge. VM rocks.
Perhaps they meant they only *support* those clients? That I could understand. I certainly don't expect Qwest to walk me through expunging just a single message with VM under xemacs. "Now type Meta-M..."

you can save a couple bucks over thinkgeek at pricewatch. But then again it's only a couple bucks, and thinkgeek seems like a decent place to support.
that can display the time since the epoch.
Handing these things off to the grandkids won't be too practical after 2037.

whoa!
perhaps you meant: it's not the size of the dog in the fight, it's the size of the dog.
Or, more appropriately:
if (! sizeof(dog_in_fight) )
sizeof(fight_in_dog);
