Windows is hardly portable and used extensively ala linux, so taking away portability, I can do way more with linux at the cmd prompt than you could _ever_ imagine with windows.
So can you run dmesg, investigate/proc, easily and programatically going through processes, go through mem statistics ala vmstat, get the temp readings with lm_sensors, run multiple UML's within the kernel(vmware) etc etc etc. all from the command line for free? That's what I thought.
meant to say that at compile time the java compiler knows it must invoke the hexadecimal conversion code.
hash.c uses sprintf which is very slow

Java Faster Than C++?

sprintf(buf, "%x", i);
It must parse the "%x" and determine what it's trying to do. So it decides, at runtime, you want to translate an integer value into a hexidecimal string. Of course if there's an error at runtime in the string "..." it must generate an error. How 'bout using strtol?
Now let's look at the java version:
Integer.toString(i, 16)
Ok, here we have something that is strongly typed so of course it will be faster. At runtime the java compiler _knows_ what it's dealing with and it knows it must invoke the hexadecimal conversion code.
Note that these statements are within loops.
Just one example, that was the first file I looked at. I don't think they have quite optimized the C++ code IMO. Plus the C++ library is notoriously slow, I would recommend rogue wave or your homegrown C++ classes.
I think the lesson here is it's very easy to write slow C++ code while it's very easy to write fast Java code.
Gimme any C++ code here and I'll profile it/speed it up and get it as fast if not faster than java.
Every country has worker protection laws, even China. Does that mean they're enforced or are strong? No. American companies would never be allowed to list age limitations, yet Indian companies have no qualms. So, in this context, the protection laws in America ar stronger.
Should Europeans who outsourced to America tax American products given that Americans don't require workers to be near a window, don't require workers to have 5 weeks of vacation and can be fired with ease?
Things are tricky. I lost my job to Indians but managed to find something more stable and well paying since I do have a good degree, do have plenty of experience, I am relatively young. But what happens when I get older.
Things are bleak and cold and confusing, the only thing that is sure is people will not think twice about letting you go if that means they can keep their job or make a quick buck.
This is why we outsource to India. Less government regulation, fewer worker protection laws, fewer environmental regulations... I mean, are we to enforce our minimum wage laws on India? No.
Well, I'd like all the facts as my parents have been dropping tidbits here and there. I wish I was as smart as other people I met at the university, I won't blame anyone of course until I find out. I guess I was just offering a hypothtical situation if it turns out my suspicions are correct.
I'm a twin and I'm not too sure what happened at my birth but I think things didn't go as planned. I'm approaching 30, just got married and am succesful so I can take the truth now. Here's what I know now:
- I know that people weren't sure if my mother was carrying twins and I came out 10 minutes after my brother.
- I know that my parents had the name of the doctor who delivered me in their rolodex and talked about him like he was their friend, leading me to believe they were in contact with the doctor well after my birth.
- I would constantly space out throughout school and not perform well, to the point where they put me through speech lessons well into 3rd grade and even held me back in 5th grade. I was told a year ago that my parents gave me IQ tests which showed I was above average IQ-wise. The tests showed that I had a logical mind and they gave me a computer, after that the rest was history, #1 CS school, good job, etc etc.
To make a long story short, I don't know everything that happened but I think something was screwy here. I managed in any case because I have never known the full truth. I'm ready for the truth I think. If some doctor botched up the birth, I would never sue since that would violate my principles. I would on the otherhand call the doctor to tell him I did well despite his incompetence.
What if the doctor in question delivered twins but, because of their screwup, left the second twin in too long causing brain damage? The fact that a jury awarded this person money tells me there's more to this story than you let on.
THE GREAT FLORIDA EX-CON GAME How the "felon" voter-purge was itself felonious by Greg Palast
In November the U.S. media, lost in patriotic reverie, dressed up the Florida recount as a victory for President Bush. But however one reads the ballots, Bush's win would certainly have been jeopardized had not some Floridians been barred from casting ballots at all. Between May 1999 and Election Day 2000, two Florida secretaries of state - Sandra Mortham and Katherine Harris, both protegees of Governor Jeb Bush- ordered 57,700 "ex-felons," who are prohibited from voting by state law, to be removed from voter rolls. (In the thirty-five states where former felons can vote, roughly 90 percent vote Democratic.) A portion of the list, which was compiled for Florida by DBT Online, can be seen for the first time here; DBT, a company now owned by ChoicePoint of Atlanta, was paid $4.3 million for its work, replacing a firm that charged $5,700 per year for the same service. If the hope was that DBT would enable Florida to exclude more voters, then the state appears to have spent its money wisely..... MORE Harper's Magazine, 3/1/02....posted by jkeels, 3/5/02
When those pirated versions contain spyware/viruses they'll see how much open source is better.. Pirated software isn't reliable vs open source software which can be signed & verified.
It will be too late for companies like mine who have purchased or are going to purchase 100s of new opterons. They blow Intel out of the water. At my profession and elsewhere it's evident that Intel is a bit late to the party, people like myself are buying opterons for server-class platforms and will keep them for years to come, we'll see if intel can get our business in a few years. Kudos to Intel's cash reserves. But it doesn't mean much when we placed that large order for those blazingly fast opterons.;)
Indeed, that would be terrible. I'm very concerned that Sun, with its large enterprise market, is moving towards Opteron servers, porting Solaris, one of the best unix OSes IMO, to it. They laughed at the Itanic and are welcoming Opterons with open arms. They have purchased opterons and the supporting hardware. Other players are on board as well, with contracts signed. I'm sure Intel could flip a switch but unfortunately it looks like more may be required. I mean, have they addressed the NUMA architecture, they can have the x86_64 instruction set and not have NUMA. They may not have the performance either, otherwise I'm sure they would have flipped that switch earlier. Then can they steal away the sun partnerships? It should be interesting to watch this play out.

uh it makes up about 50% of online ad revenue so it's somehow effective. More clickthroughs = more actions.

American companies cannot do this, period. The military gets away with all sorts of things like this.
