Afaik, the loopback-encryption is currently broken in the development kernels (might be fixed already) and there might be changes in the crypto API with the release of 2.4. Moreover, I've hardly tested the patch, so all in all, I think it's reasonable to wait with a release until 2.4 and the appropriate fileutils are out (patches on patches aren't fun, btw.).
The FreeBSD vs. NetBSD error has already been adressed, and for the ISO image: there's absolutely no problem to create your own bootable OpenBSD CD: the 2.88MB boot-image is free and as a bonus you can customize the contained software to your architecture and other preferences and will probably be able to fit the whole system and software on only one CD (including source).
this ain't true: there's absolutely no problem using a loopback-ecrypted patition as swap-device.
Ramdisk in memory
absolutely pointless, since the encryption keys have to remain in (unencrypted) memory anyway.
I have the impression that some guy's miss the point here: encrypted partitions are not (primarily) meant to protect against intruders on a running system (a 2nd reason why encrypted ram is basically pointless) but to protect against theft, confiscation, seizuere (or whatever the legal pretext of the day may be called) of your hardware. It's about ensuring that once the power is turned off, there remains absolutely no recoverable data on the system.
Therefor it is, btw, reasonable to encrypt the swap partition with a random key transparently generated on startup (I've patched losetup to provide this very option.)
Just like Grover's original search algorithm, this new extention to more flexible search terms still requires O(srqt(N)) quantum operations. From the abstract:
[...] This yields new applications - an algorithm is presented that can create an arbitrarily specified quantum superposition on a space of size N in O(sqrt(N)) steps.[...]
So while providing a significant speedup over the classic O(N/2) steps, this search algorithms does not overcome the barrier from exponential to polynomial search times (like e.g. Shor's quantum algorithm for prime factorisation); i.e. you would still require O(2^(k/2)) steps to find some k-bit string.
If you are interested in quantum computation, check out QCL, my quantum computation language and QC simulator (for Linux, you guessed it;-)). An implementation of Grover's original search algorithm is included in the tarball.
Well, sure they could! But from a business perspective, this would only work if they find licencees who are willing to pay just for being able to close up their modifications (and not for using the code in the first place). And why should anyone do that?
This is not some basic library for implementing huge projects (like e.g. Qt) with 100000+ LOCs but a game engine where the sum of all "derived code" (in the GPL sense) will very often be several orders of magnitude smaller than the original code (esp. if it supports some kind of scripting) and most of the work is spent for art and level-design. And since the copyright on the artwork is more than enough to prevent some enthusiasts from developing a standalone free clone while the game is still on the shelves, it would simply make no economical sense to pay much for a special licence.
As part of my master thesis, I've developed a programming language for quantum computers. While the interpreter is still somewhat experimental, it works under Linux and the best part of it: it's Open Source (GPL). So if you want to play around with quantum algorithms and can't afford the real hardware, you might want to give it a try.
If your monitor doesn't happen to "work with X" right off the bat, it seems that you're out of luck.
This usually dosn't have something to do with X itself but with those fancy graphical installation programs, which aren't capable of generating proper modelines.
Even Windows 3.1 didn't have the sort of monitor problems that plague X.
Sure, but you're usually stuck with 60 Hz SVGA and a very limited choice of resolutions. And there's no way to get it to run on more exotic hardware like fixed frequency Workstation monitors.
Modelines. I know there are programs that help with this. Which ones do you all suggest?
I've made the experience that the best program to generate modelines is still the offical X installation tool xf86config, which usually comes up with a usable mode you can then fine tune by just using the monitor controls. No need for specialized programs unless you really want to go to the limits (but then you're better off with a pocket calculator and a text editor, anyways).
I'm astonished that many people here dismiss V2 OS as useless toy without thinking of the most obvious use for a small x86 OS: having a full featured OS which entirely fits into the BIOS flash-ROM. Some applications, that come to mind:
BIOS setup (including remote administration)
networked system updates
backup and restore software
a clueful bootmanager
tools for doing flash-updates on PCI-cards etc. (i.e. something like/dev/bios)
desaster recovery tools as boot-sector restorage and debugfs
networked access control
I wonder if this could give another boost to the OpenBIOS project, as their current code base hasn't gained critical mass yet to allow for efficient and distributed OpenSource development.
Could they really think that somebody who doesn't have Linux will buy the Linux version of a game and install the O.S. to play it?
This won't be necessary, since you can get the Windows binaries from the net. In fact, it's a perfect opportunity for anyone who wants to give Linux a try, as he will get an up-to-date distrib for free (not to speak of the cool tin case, which is supposed to be Linux-only), and still can play Quake under Windows should he be inclined to do so.
Also, I hope they're not expressing a bias toward a particular Linux distribution.
SuSE is Loki's retail-partner in Europe - my CivCTP version also came with a SuSE 6.1 CDROM. I don't think that id-software has much to do with this decision.

The connection between the psycho company and the software giant is a thorn in the eye of large church sect-observers.

3. If the Distributions contain derivative works created by you, you must place a Notice in the source code of the derivative works stating that your derivative works are being made available under the NCL;
Considering that the proposed NCL shows the same transitive property on derived work as the GPL, this would create another disjoint set of OSS incompatible with anything else. In the case of Novel, this is esp. problematic, since - considering their business - they probably won't use the NCL for mere end-user applications, but for low-level stuff with will require massive kernel-interaction.
If this trend to incompatible OSS licences continues, the resulting balkanisation will negate the greatest advantage of OSS, the possibility to freely share code.
SuSE Linux AG, Europe's leading Linux distributor, [...]

"[...] Napster that allows anyone to become a publicly accessible FTP site [...] although no Linux version is yet available.
Ahm, just about every Linux distibution includes at least the BSD ftpd and the wuftpd. If this napster thing is just another file transfer protocol then it deserves to die anyway as the free ftp protocol already does a fine job on this. And if it's just another Win9x ftp-server, what the hack is the news here? (If there are really some lawyers to sue yet another ftpd, than this story should have better been put under the "humour" section.)
You probably mean the EPIC report "Cryptography and Liberty 1999 - An International Survey of Encryption Policy".
Germany is rated GREEN for 1998 and 1999 which "signifies that the country promotes or has expressed support for a policy that allows for unhindered legal use of cryptography, such as adopting the OECD Guidelines." The US ratings, for comparison, are YELLOW/RED (1998) and YELLOW (1999).
No matter that such official Chinese government sponsorship might add a quarter of the planet's population to our user base; if this is "world domination", we'll want none of it.
I find this statement outrageous, esp. from ESR who coined the term OpenSource as a non-political substitute for "free software" and now abuses his (btw. well earned) authority to air his personal political views as those of us all.
I for one have no problem if one quarter of the planet's population embraces Linux instead of using a non-free OS (and readily exported commercial US product, I might add) and that ESR blatantly denies them their right to do so is an insult, not only for the Chinese people, but for every programmer who wrote free software as a gift to all people under the premise that it shall be used, distributed and improved in a free manner by everyone who wishes to do so.
Don't get me wrong, I also feel pity for all the victims of the Chinese dictatorship, but I also think that free software is a better means of spreading the idea of freedom than dogmatic cold-war reflexes and in the (IMHO very unlikely) case that this is not a hoax, at least for one time, the Chinese government had showed more mental flexibilty than ESR's anti-communist rant.
While until last year SuSE has positioned itself as a rather conservative distibution, only impementing proven technology (no glibc2 for over a year, KDE instead of GNOME) their X-Server efforts being the only visible exception, RedHat has always been the "bleeding edge" choice among the standard distributions.
This seems to have changed dramatically during this year: after embracing ALSA (i.e. hireing the top-ALSA developer and making ALSA part of their distribution) and publishing their next version also on DVD, SuSE now also seems to be the first distib to include a working journaling FS and is actively funding its development. Considering their recent expansion efforts (esp. in the US and Eastern Europe) and their actually positive balance (instead of RedHat, they do make some money now), I can't wait for their IPO!
As most MBs come with a (usually almost empty) driver CD anyway, there wouldn't be any additional costs. And even if they shiped their own CD, it is resonable to asume that this would be paid for by Corel's marketing department and not by the MB manufactor and it's customers. (Not that the few cents for a CD would qualify as a "tax", anyway.)
While distributing Linux CDs with Motherboards is certainly a nice publicity stunt, which even might bring us some new converts (don't expect too much, though), its practical value for the Linux community isn't much higher than the occasional Linux CD that comes with your favorite computer magazine. What really would make a difference (in ascending order of commitment) is e.g.:
Full kernel support for all MB features: One might think that should be a matter of course by now.
A BIOS flashing utility for Linux: How many people still keep a small DOS part. for this very purpose? (Yes, I kown about the/dev/bios patch, but that alone won't cut it.)
LILO integrated into the BIOS: Well, that would be cool, wouldn't it?
BIOS setup utilities for Linux: Batch installing 1000 PC's including BIOS settings with a Linux boot-disk could really make a difference for OEMs.
Check out the "back door" entry of the Jargon File to learn about one of the IMHO most creative hacks of all time:
[...] Ken Thompson's 1983 Turing Award lecture to the ACM admitted the existence of a back door in early Unix versions that may have qualified as the most fiendishly clever security hack of all time. In this scheme, the C compiler contained code that would recognize when the `login' command was being recompiled and insert some code recognizing a password chosen by Thompson, giving him entry to the system whether or not an account had been created for him. Normally such a back door could be removed by removing it from the source code for the compiler and recompiling the compiler. But to recompile the compiler, you have to use the compiler -- so Thompson also arranged that the compiler would recognize when it was compiling a version of itself, and insert into the recompiled compiler the code to insert into the recompiled `login' the code to allow Thompson entry -- and, of course, the code to recognize itself and do the whole thing again the next time around! And having done this once, he was then able to recompile the compiler from the original sources; the hack perpetuated itself invisibly, leaving the back door in place and active but with no trace in the sources. [...]
A detailed description of the hack by Ken Thompson himself can be found here.
This is ridiculous! Civil disobedience is disregarding a law on purpose in an exemplary yet harmless way in order to provoke legal consequences and generate martyrs to expose its perceived injustice; it's about taking personal risks. Neither is the case here.
The only way to undermine the tapping efforts of the NSA an its partners is to make encryption ubiquitous, which is sucessfully defied by US crypto regulations: While it is still possible to get strong crypto for everyone, it can't be made part of the default installations of mainstream OSs (at least if they are developed in the USA).
A real civil disobedience campaign would be e.g. if a significant part of US websites mirrored an easy to install package of free encryption software together with a note stating that this is known to be in contradition with US export laws and naming the responsible persons. But since this would mean real commitment and real risks for the activists, it's not likely to happen.
The effect of the TGPL would be exactly the same as using GPL while asking contributors to sign the copyright over to the originator (the usual practice of the FSF) or explicitly granting them permission to sublicence the submitted patches. You can provide standard agreements in the README file like this (IANAL, so this will certainly require some legistic fine-tuning, but you get the idea):
If you want your contributions to be incorporated into our source-tree, please include one of the following statements into your submission:
I hereby assign all rights of the submitted material to [originator], provided that he will release this submission under the GPL; all other rights of [originator] esp. the right to make additional licence agreements shall be unaffected.
The submitted material is (c) by [contributor] and may be distributed according to the terms of the GPL. I addition to that, I hereby grant [originator] the exclusive permission to additionally licence this submission under arbitrary terms.
A simple script at the submission-account can check incoming mail for these notes and reject submissions that don't comply. In the end, you get the same effect as the proposed TGPL without having to deal with yet another open source licence.
Unfortunatly, it won't, as Myth II only supports hardware acceleration on 3dfx cards via the glide port; OpenGL support is not even planned. To quote briareos, a Loki developer on loki.games.myth2:
You're really asking "will we take the time to write an OpenGL rendering module for Myth2"? The answer is: if someone finds the time. That's all I can really say.
Check out Star Trek Is SATANIC. Even more funny than the page itself is the guestbook. (As a European, the US ability of taking even the most absurd religious parodies for real never ceases to amaze me.)
If you want to compare the speed of the generated code, you better look at the times the programms spent in user mode instead of comparing the elapsed times, so it's 26s vs. 72s and not 42s vs. 4m31s.
So ccc generates code about 2.7 times faster than gcc without optimizations. If the speedup with -O2 is really about 100% that you end up with a 40% overhead, which is not great but IMHO an acceptable price for portability.
