"The U.S. effort to abolish leap seconds is also firmly opposed by Britain, which would further lose status as the center of time. From 1884 to 1961, the world set its official clocks to Greenwich Mean Time, based on the actual rise and set of the stars as seen from the Royal Observatory in Greenwich, just outside London."
I had no idea there was still a physical basis for this. I assumed there was a master atomic clock.
I can see why the USA would do this: they move around the holidays to fit the work week (e.g. Monday or Friday, whichever's closest). Try doing that with Corpus Christi in Continental Europe: it would be considered totally absurd.
My experiences with striving Indian liars were in Silicon Valley. They and their families were rich -- so it wasn't fear of becoming a guy who removes poo from your house (with his bare hands) that motivated them. There were some of the most blatant liars I ever dealt with.
Everyone else that I ever talked to about Indians in the Valley said the same thing: these people are compulsive liars.
One Indian stole diagrams from my friend (from his thesis), and gave a talk with them. When the guy said, "hey, those are my diagrams," the Indian lied and said, "no, they are mine..." This guy kept track: of 12 engineers that he dealt with, 11 lied to him (and stabbed him in the back). One of 12 was decent.
Again, these guys were not looking at becoming the types who scrounge through the garbage at the dump, looking for valuables to sell to scrap dealers. It was just how they were.
So based on my experience, that's why I say what I say. If you've had a different experience, that's great. If Indians are better people that Euro-Americans, great -- I suggest you go to India, and live your life among your chosen friends.
"Witnesses describe the existence of distinct units known for committing particular crimes, like the Burn House Unit, Cut Hands Commando, and Blood Shed Squad. Some of these squads had a trademark way of killing such as the Kill Man No Blood unit, whose method was to beat people to death without shedding blood, or the Born Naked Squad, who stripped their victims before killing them. The closer ECOMOG forces got to rebel positions, the more these squads were mobilized and sent on operation."
I can't fathom why the govt. funds PBS (e.g. Monty Python, Benny Hill), yet won't fund embryonic stem cell research.
The government funds NPR (radio typically enjoyed by a minority of Americans), yet won't fund something that might arguably benefit all Americans. Furthermore, the benefits of the funding go to private people, not the govt. itself (Australia is different in this way).
The inconsistent policies of the government are irritating; funding all or none, or perhaps using some market mechanism to decide what to fund -- all those would be more consistent than the current system.
Also, if you know how the research works, it is really ridiculous. A researcher has his pet interest. Over the decades, he pitches it as, "good for Star Wars missile defense", "good for internet" then "good for anti-terror" -- whatever it takes to get the money. That's really irritating.
They could have just called the local cops or state police. Did they really have to call the Federales? That seems a bit extreme. It looks like a simple case of reverse engineering.
Also, there's plenty of info that Cisco was cooperating up to the very end -- there was no big surprise. He just didn't do exactly what they wanted.
Hopefully the FBI will see it that way, after they investigate. And I hope homeboy's affairs are all totally clean, so that the FBI wraps up quickly. Now I get why people just release this info anonymously.
That story of the jihad guy is really something! But in that case, it wasn't that he was hacking for Osama. He just happened to be a jihad-lovin' software guy. I hope they "go Taliban" on him in prison. I hear the blacks are really hard on people like him.
Most "Japanese" cars sold in the USA are made in North America by North Americans. More and more they are designed by Americans. The Japanese have imposed a system of management that leads to ever-better, higher quality products at lower and lower prices. The workers are North Americans.
Also, Japanese engineers can impose technically-motivated decisions on the MBAs. This has happened with auto features: the engineers insisted on certain features, while the Japanese equivalents of the MBAs said "they cost too much". In Detroit it goes the other way.
So I'm missing your point about "incompetent, raw-fish eating yes men." The Japanese car companies are better run companies (and better to work for) than Detroit.
And I suggest you try working for/with a bunch of Indians (or greasy American MBAs who see them as the way to get away from crabs like me). Maybe you'll sing a different, less-PC tune. India has around a billion people. There are many smart, driven ones in there. And there are a lot of striving liars who will say anything to make a buck.
Thanks for summarizing the article so well. It does basically come down to, "Oy weh! So much money for talent I must to pay. These geeks, they only want to work with other geeks."
Many smart workaholics want to work with other smart workaholics. Geeks with no social lives want to goof around with other geeks with no social lives. They don't like stupid frat boys. No shit?
Outsourcing to India is the dream of the MBAs: replace the arrogant, irritatingly smart and in-yo'-face engineers with a bunch of compliant, diaper wearing yes men. But then it turns out the Indians lie a lot and are unqualified, so its a big bust. Ha ha!
At my last job they hired a guy and thought they were finally free of their dependence on me. E.g a replacement for the asshole. Then they realised, "oh shit, that crabby mofo is really much better than everyone else. Crap. Not free of him yet. Still have to put up with his demands and KMA-attitude."
Lynn shows how to do a remote exploit on Cisco's firmware. This is impressive because the router runs software that attempts to detect inconsistencies. It will reset itself and start up afresh. The big deal is that Lynn shows how an exploit can fix things up and avoid those measures. Basically, his technique is like a ninja, that breaks into a building through a window, but then immediately reassembles the window before the security guard making his rounds can notice that the window got destroyed. That's it!
There's no indication Lynn stole ANYTHING from Cisco, or broke any law.
Lynn apparently "reverse engineered" the OS in order to do this. That's usually fine; it is his right to do that.
Considering this, I'm pretty pissed that Cisco's spokeswoman, Mojdan Khalili, said that Lynn broke the law (without saying what law it was). I think that could be libel (or slander -- I'm not a lawyer) -- in any case, Mojdan Khalili, working for Cisco, just ruined this guys rep, and sicced the FBI on his ass.
Perhaps if you write her, she will get Cisco to ask the FBI to lay off the good researcher (ask her to have Cisco "take it all back"). From yesterday, here's her contact info:
978-936-1297 mkhalili@cisco.com
Also, some total jerk looked up her address and posted it (here). I think that's totally inappropriate; if you show up on her doorstep and bother her, I hope she calls the FBI on you, you freak!
Our friend Mojgan Khalili is the Cisco employee mentioned in the article, who said the security researcher broke the law -- "It is especially regretful, and indefensible, that the Black Hat Conference organizers have given Mr. Lynn a platform to publicly disseminate the information he illegally obtained."
If you'd like to write to Mojgan and say that you don't like their attitude toward full disclosure, or their attack on the guy who's working hard to make things secure, here is his information.
If nothing else, you could ask him "what law did the guy break, biatch!?!"

Introduction
Karl Fogel is a founding developer of the Subversion project. Subversion is sponsored by CollabNet and under the company's employ, Karl describes himself as the CollabNet-to-developer liaison. In the following, Karl explains the inception of the open source Subversion project, what it has required to build its community, and what he has learned in order to successfully maintain it. Karl's vantage is interesting not just from the perspective of managing such a community but also because the Subversion project itself is one of the required sorts of software technologies used in open source development.
Subversion is a type of software configuration management (SCM) tool known as a version control system. These types of tools are important toward letting developers collaborate on software projects. Subversion is part of the tigris.org community's focus on building collaborative software development tools. CollabNet provides enterprises with distributed software development solutions. It's used by companies such as Sun Microsystems, HP, and Barclays Global Investors to help coordinate development teams spread out around the world.
Part III of the Concerted Disruption, Climb Aboard series.
We started Subversion about five years ago, and I think it is a little bit different from a lot of open source projects because we started with the goal of replacing a specific piece of open source software... We were trying to replace CVS.
You had a good reference point.
We had a great reference point and also that saved us from a lot of arguments about what should and shouldn't be in our first release. We could say that if it's in CVS it should be in our 1.0 version, if it's not in CVS it doesn't need to be. There was an inherent controversy reduction substance in our projects--at least before 1.0. Now we get into all those discussions that we put off. But we have a foundation/relationship already built with all these people that makes it a lot easier to do that because they all worked together to get to 1.0.
As to how we got those developers. The numbers we have right now are roughly thirty full committers--people who can commit anywhere in the source code, thirty partial committers--people that just do documentation fixes, fix support scripts, or something like that but do not have commit rights in all the code. Of those thirty full committers, I'd say roughly fifteen are really active on a day-to-day basis. You get some others that come flying in like Han Solo every now and then--they fix a bug and then they go out and you don't hear from them for a few months.
The way we founded it was mainly word-of-mouth. We knew the CVS space pretty well, we started contacting those people, they talked to their friends, and pretty soon people just showed up. We actually held physical, open-to-the-public design meetings when we began the project in San Francisco. Some of those people are still with the project today. But you know, one of best committers is in Slovenia and he certainly didn't come to those design meetings. But we wouldn't be where we are without him.
Could you please clarify your role in the project?
I guess you could call it, founding developer. CollabNet only employs somewhere between three and four of those committers. We don't all work 100 percent on Subversion all the time. Somewhere between three and four is accurate. My role was mainly--you know I had a lot of experience working with open source projects before, and in particular with CVS, which helped to get me involved with version control--it was sort of to set the tone at the beginning of the project--a CollabNet-to-developer liaison when necessary, although there haven't been that many conflicts, we haven't n

Exactly -- there's a reason they've been using Symbian. Supposedly, it does the job it is designed to do.
If Nokia wants to switch to something else, they'll take on some risks, but perhaps it is worth it given the $140 million they have to pay out (just next year! -- nevermind the future).
I suspect that having used Symbian for a few years, they know what Symbian-like features they need (and which they don't) in order to port over the apps they need. That would imply "they've outgrown Symbian." Adding those needed features to Linux (and releasing them ala the LGPL, right??!?) would make sense.
However if they have to add so much crap to whatever Unix-like OS they use, why not switch to NetBSD, and keep it all closed source? That would seem to be a more rational business decision, given that their apps require only the services of a Java runtime, and not any Linux-specific features.
I was trying to figure out why payola bothers Americans.
I don't think it is simply that radio stations are using a public resource -- if all radio was private (ala Sirius or XM), I think folks _would_ mind a bit if stuff was getting paid because the company was getting stuff in return. But I think they'd mind less, because they'd figure that Sirius can do with its spectrum what it wishes, because they've paid for it.
I think what bothers folks is the fact that it is done in an underhanded, secretive fashion. This last case took it to whole new levels of Talmudism (just RTFA to see).
Imagine if they said, "this next Madonna song was sponsored by EMI. Madonna is so great! Buy the album." I just don't think people would mind so much.
If there can be some real competition in the processor market, that will be great for consumers.
Anything (anything!) to increase the competition will be good for consumers.
Furthermore, the Chinese will slash the prices to almost nothing -- and we all know it.
They take a perverse pleasure in doing this against their competitors (because they can) -- it is how they throw their weight around, and cut off the air supply of their competitors.

This article points out (inidirectly) what little control users have over their own windows environment.
With BSD, you can strip out drivers (e.g. USB drivers that could cause security problems), change init, change boot, dual boot, blah blah blah blah.
With Windows, you get what's in the box. That's it.
And you can be sure that if this guy's hacking pisses off windows, he'll get cease and desist letters, or a DMCA blah blah blah...

Some have mentioned "scalability" as a problem -- what is this problem? Is it really a problem?
E.g. I have to merge 100 patches --- takes a long time. [this can't be it; if so, that's really bad].
Or when 10 people try to use it on a project, they wind up having to talk to each other too much?
Does anyone have good/bad things to say about Darcs
It is written in a purely functional language. The stuff is rooted in a theory of patches.
Does this stuff actually work? Subversion seems like a reworking of CVS (minus the warts). Darcs seems like a different animal.

Oh -- I figured the linux kernel was LGPL. I guess it is GPL. But I thought there were non-free components in there too, so I figured it was LGPL.
Exactly -- there's a reason they've been using Symbian. Supposedly, it does the job it is designed to do.

So you could hack up USB device (e.g. a flash), send it to a company, and kaboom.
