  1. Non MS-DOS/Windows book on Assembly Language for Intel-Based Computers, 4th edition · · Score: 2

    For those without access to an x86 machine, but who do have access to a Sun box, I can wholeheartedly recommend "SPARC Architecture, Assembly Programming, and C" by Paul. I learnt assembly programming from it, then x86 assembly with NASM and a PDF I found on the web. The SPARC architecture seems much more coherent, and Paul's book was actually an enjoyable read - not what I ever expected to say about a book on assembly language programming.

  2. Re:NetBSD in OS X on NetBSD Now Supports Dual Power PC Processors · · Score: 3, Informative

    I thought the point of this was so that the NetBSD portion of OS X's Darwin would finally be capable of utilizing dual CPUs

    Mac OS X uses portions of FreeBSD (user land bits mostly), but is built on top of the Mach microkernel. Mach began life as the BSD Unix kernel, but was extensively rewritten as an academic attempt at a working microkernel. While on his extended hiatus from Apple, Steve Jobs founded Next, who used this microkernel version of BSD in the NextStep operating system.

    Mac OS X is arguably NextStep given a bit of a makeover, hence the continued interest in GNUstep as a free version of OpenStep (and now the newer Apple API's). OpenStep was the user land API's from the NextStep operating system, packaged up to run on many other systems.

    The Mach kernel was adapted for multiple processors a long time ago, but I don't think the support was completed until Apple released OS X. So basically, NetBSD SMP support is something independent from Mac OS X's.

    Yup, the Metal theme isn't to everyone's taste. You can also select native Look and Feel, which I believe is the default on Windows. On Unix the native l&f mimics Motif, albeit badly. The MacOS l&f used to ship with the betas of Swing, but Apple pressured Sun into dropping it - but for a while I could fool people into thinking I was running a Mac app on my Unix box.

    A few people have attempted to create new l&f packages, most notably a NeXTSTEP one. But the major amount of work involved in producing a full l&f means few (if any) have been completed. At least that was the state of things last time I looked aroud for one.

    I'm wondering how you can tell if UsePrivilegeSeparation is working?

    Login via ssh, and run:

    You should see two sshd processes, one with the UID of 0 (root), and the one you are logged in via which should have your UID and "[priv]" in its command name.

    If it's not like that, then try restarting sshd. On a RedHat machine run:

    /etc/rc.d/init.d/sshd restart

    Don't know what the init scripts look like on Debian, but you could always kill sshd manually and start it again.

    Also make sure you're picking up the configuration files from the right place. They moved from /etc/ to /etc/ssh/ in a recent version.

  7. Re:any reason for slow releases on NetBSD 1.6 Has Been Branched · · Score: 4, Informative

    I don't know about FreeBSD, but OpenBSD follows a six monthly release cycle fairly rigidly, giving the developers a target for adding new features and stabilising them. It must also provide a crude way to estimate revenue, as CD sales obviously peak around the time of a release.

    NetBSD has some different goals to the other BSD's. Correctness of the implementation of any new feature is valued highly, leading to a conservative development process. The SMP implementation is a good example - the NetBSD developers want to get it right, by comparison the Linux philosophy calls for early release of potentially buggy code. The Linux principle is that exposure to a wide audience will shake out bugs quickly. NetBSD relies on the fact that the most of the "audience" don't have the skill to fix bugs or even provide meaningful feedback. We could argue about which approach is best until the cows come home, but that's the way it is.

    So in conclusion, NetBSD is released at a leisurely pace but this shouldn't be taken as a relection of how much development is going on.

    As I understand it, this will be the first release where all architectures are ELF based. No more recompiling the linker to avoid annoying warning messages on the Vax! The compiler will also be brought more upto date, and X will be version 4.2.0. Having followed the NetBSD security mailing list for a while, there will also be some nice little tweaks to the default install.

    I'm a little bit unclear on whether this release will feature native threading support, which is the only API I'm missing from a certain other Unix-like operating system. Anyone reading know the score on threading support in 1.6?

    RPM wasn't a duplication of effort, more of a parallel development. This happened quite frequently in Linux world of the mid nineties - anyone remember the alternatives to the ext2 filesystem (I can't even remember their names now)? We still see it with the proliferation of journaling filesystems.

    To see it as some anti-Debian conspiracy is to exhibit unfounded paranoia. The Debian project works to its own agenda, and a pace that some find exasperating, so please don't start anti-RedHat FUD on the basis of that.

    As for the merit of porting dpkg, etc. - why would you need to? They already run on most architectures, it just comes down to a choice of distribution. *Personally* I prefer RPM because it handles dependencies and versions in a much more sophisticated manner than debs do. This was borne out of a tedious discussion on my local LUG mailing list, where a Debian contributor bad mouthed RedHat and RPM in particular, and was promptly made to look a fool.

    It's even more complicated than that ...

    British ant-aircraft systems were well integrated, and benefited from Hitlers insistence that the Luftwaffe switch from military targets to cities. Had the Luftwaffe continued their attacks on British airbases and defence installations as they had at the start of the Battle of Britain then the outcome would have been decidedly different. Despite outnumbering the Luftwaffe (a little known fact) at the start of the Battle of Britain, RAF losses had almost crippled defence activities prior to Hitlers directive.

    As for the technical superiority of aircraft, it varies from model to model. The Me109 had too short a range for really effective bomber escort, but with the was well matched against most enemy fighters until quite late in the war. The Focke-Wulf Fw190 (which was eventually renamed the Ta152 for its final versions) was far superior to British aircraft, and an equal to the American mustang. What the Germans lacked was large, long range bombers, and a really good close support aircraft like the Russians crude but heavily armoured Shturmovik.

    As for tanks, the Tiger I, Tiger II and Panther were the best tanks of the war. They suffered from being too complicated, and thus slow to build. The Russians could produce vast numbers of the crude T-34, and afford to lose them and their crews. The Germans escelled at recovering damaged tanks, but this couldn't counter the Russians massive numerical superiority. Earlier tanks like the Panzerkampfwagen IV, which formed the backbone of the Panzer divisions, could hold its own even towards the end of the war. The PzKW IV had some trouble against the T-34 when it first encountered it, but its better trained crews and good armenent countered this.

    When I worked in the US, I was amazed at how biased the press was. The Arabs in the Middle East are painted as irredeemable devils, and the Israelis as put upon victims. In the same way, I was shocked at the US portrayal of the Northern Ireland problems - but saw disturbing parallels.

    Nothing is black and white. The British army was sent to NI originally to protect the Catholic minority. The Israelis occupied Palestinian land in the late 1940's relying on some archaic biblical texts, and the worlds collective guilt at what had happened to Jews (amongst others) in Nazi occupied territories.

    Now we see the fruits of Americas unquestioning support of Israel. US foreign policy in the Middle East was so polarised along pro-Israeli lines for so long, that in the eyes of many Arabs and Islamic extremists the US and Zionism are indistinguishable. And since a poorly armed people can't take on tanks and state of the art military aircraft, ordinary people who just happen to be in New York suffer.

    So before whining about terrorism, another Pearl Harbour, etc. look to your own politicians and press. If they gave you a more balanced view of the world (the press), or had shown more spine when dealing with the Middle East for the 40 years (the politicians, Carter and Clinton excepted) then you wouldn't be seeing dead bodies pulled from rubble in US cities.

    Then the original owners who had bought the hospital from the NHS went bust. The subsequent owners stripped the slate roof off and let the building decay. They wanted the land the building was on for houses, and thought that if the building decayed to a point where it was unsavable they would get permission to pull it down.

    Instead the council sued the f*ck out of them, and a new consortium finally stumped up the cash to restore it. They got permission to build houses on what had been the gardens, as they had run to rack and ruin.
