This method causes the firewall to act as a bridge instead of a router. The advantage is that the firewall is not IP-addressable. To hack it, you'd have to go down to the MAC layer, which is generally only possible if you're on the same network segment.
I read the SysAdmin article a month ago and thought the same thing. The OpenBSD Invisible Firewall is a much better solution -- you can't hack it from the outside, but you can still make any changes necessary without causing downtime.
Actually, the Linuxgruven bumper sticker was around before the company. The bumper sticker *was* a Far-from-pukin joke knock-off. The bumper stickers were printed by LinuxCare, who was not too happy with someone taking the name.
They've got a note on their web page saying that you cannot use the multi-room video capabilities if you have Wireless Ethernet. I suppose that would be "re-broadcasting" the TV signal. I don't think there's any way for it to tell whether you've got Ethernet or Wireless Ethernet though. So it's probably just the honor system.
I agree whole-heartedlt that UNIX Power Tools is an excellent book. It's the only book that I have at work, and serves as an excellent reference to UNIX command-line arcana.
However, it is geared toward a completely different audience. It is a reference manual for seasoned UNIX users, not Linux newbies.
Let me see if I can help straigthen things out here. I'll start with the GUI itself, then move on to the APIs used to build GUI apps.
Most UNIX-like systems use an X11 server to draw graphics on the screen. MacOS X does not use X11; instead it uses Quartz, a Display PDF server, derived from NeXT's Display PostScript server. (The GNUstep project is working on a DPS/Quartz server running on top of X11.)
X11 and Quartz only provide basic drawing capabilities. They don't provide widgets such as menus, toolbars, scrollbars, etc. So a widget toolkit API is layered on top of the drawing functionality. In X11, common widget sets are KDE/Qt, GNOME/GTK, and Xt/Motif. Most of these APIs try to shield the programmer from having to access any of the low-level rendering calls. There are versions of Qt that can run without X11 -- the front end and back end are completely de-coupled.
MacOS X provides 2 different APIs for GUIs: Carbon and Cocoa. Cocoa is basically the NeXTSTEP/OpenSTEP API adapted for use within MacOS. It contains most of the old NeXT stuff, plus some functionality from MacOS 9. It is accessed via Objective-C. (The GNUstep folks are attempting to emulate most of Cocoa.) Carbon is basically the old MacOS 9 API in C adapted to use Quartz and the other lower-level functionality of MacOS X.
Back in the 80s, rumor had it that the NSA was filtering email and Usenet news for keywords, such as "bomb", "nuclear", "explosive", etc. The solution that many came up with was to overload the system by including such keywords in every message.
If you really want to counter-act such a system, always add some of the keywords on the list to your emails. Not even the government can afford to monitor every single email.
Also remember to encrypt everything. That raises the amount of work the government would have to do even more, reducing the number of messages they could actually monitor. I'd recommend PGP or GnuPG.
XSnow was much cooler than XEyes. (XSnow has snow falling in the background of the screen, and it piles up on the top ledge of windows and the bottom of the screen.)
XPenguin isn't bad either.
He lives with his wife and two children in an apartment in San Mateo and was working on a doctorate in computer science.
Which makes it sound like he was living in the US before he was arrested. The only reason he's living in San Mateo is that the US won't let him go home to Russia. His family had to be flown here to live with him.
Microsoft is leveraging its monopoly with Windows and it's strong position with Office, MSN, and Hotmail to force or coerce everyone to use their Passport service. How can you prevent this leveraging of one monopoly to gain another monopoly? Especially given the fact that Microsoft has already gotten away with such leveraging several times before. (Also, can you comment on Microsoft's statement that they want a cut of every Internet trasaction?)
An oversight board would imply that a "real" resolution to the problems with Microsoft violating anti-trust laws was shot down. Given that, how do you expect to do anything about any violations that you find Microsoft doing?
I don't see why the same technique can't be used with other imaging methods instead of ultrasound. For instance, CAT scans, X-rays, or MRI images might be more useful in various situations.
If the wording in the treaty truly says "composers, artists, writers" that's actually a good thing. That would give the actual artists more power over the companies that "own" the rights to their works.
One problem with firewalls (especially packet filters) is that it's hard to know exactly what data is flowing through. You can really tunnel any protocol over any other - you just need to know how to encapsulate and decapsulate it. Distinguishing whether data is regular data or encapsulated data of another type is hard to do. So I suspect that security people are going to have a hard time, unless we can convince the developers that they *need* firewalls and to stop tunneling holes through.
Many of these ideas are covered better in "The Hacker Ethic". It does a much better job than this article, and takes a more studious approach. It also includes a secton written by Linus Torvalds.
How is the problem of distinguishing a.75 voltage in your ternary system different than distinguishing a.5 voltage in a binary system?
A/D controllers do this all the time, for larger bases, often on the order of 256 to 24 million. Granted, the digital results don't have logical consequences. But you can't ignore the fact that binary systems have to set tolerance levels just the same as ternary systems.
I thought all TV in the UK was pay. I.e. the governement collected money for each TV you own so it could run the BBC.
DMDA is close enough to DMCA that we can just take our anti-DMCA stuff and just change one letter.
This is terrible. The protesters get broken bones, and the cops don't even get the joy of beating them.

It is inevitable that the Big Media companies will sue them. They might as well sue themselves to get it over with.

Actually, it doesn't even do video capture.
Because a lot of people don't know that they're being milked!

Base 2 has the property that there is no base that is more simple. It fits the old maxim, "Make it as simple as possible, but no simpler".
(Unless you count base 1. I consider the tally mark to be base 1, but it has some problems fitting in as a true number base.)
It's already in stock at CompUSA. It was in their ad this weekend.
