Ever hear of netdump or diskdump (probably Redhat Enterprise only, I haven't really checked). Netdump is definitaly a pita, although that is largely because of some dumb design decisions on Redhat's part. Diskdump will be quite nice once they get some more hardware (disk controller) support for it.
The basic idea is that you send (or write to disk) the *entire* state of memory and useful sysrq data (stack traces of all threads, memory allocation info, etc) so that it can be debugged later.
Netdump just throws bits at the nic on a very low level so you better be sure that the receiving end has a reliable link to all the machines it services. Diskdump should make that a bit easier...
> A question does anyone know why the low clock speeds? Marketing, Stability, Price?
Heat. They can run at 2.2 and still beat out the fastest Intel has but consume nearly half the juice (good for data centers with strapped heating/power requirements).
I work for a major bank that uses OSS (and linux) heavily and, to be honest, we don't want to not contribute our changes back. Maintaining patchsets against ever evolving OSS is a PITA. You want new/different functionality, you write a patch (on company time) and make your case, nobody wants to be stuck constantly trying to apply your 'customizations' to a constantly evolving set of code (let alone mention how bad things get if the OSS version everyone else is using takes a split in the opposite, incompatible direction).
On a side note, Sleepycat is an awful reference for anything to do with the GPL. They've twisted it in ways that none of us would like (redefining 'redistribution' to include putting their binaries/code on a private (read: company intranet) netowrked filesystem, etc.)
Strictly speaking, no. But the law requires that higher-ups in the company be able to sign off on everything from the accounting ledger to documents filed with the SEC (which, especially in the banking world, is a *lot* of paperwork). What this amounts to is that, especially in a large company with a lot of employees, people want very fine grained access controls on everything with detailed audit logs fo a minimum of 7 years. Enter IT... To get an idea of the minutia involved, imagine having to make it so that independent auditors who don't know our systems (and, all too frequently, don't know a lot about large scale systems in general) can verify that particular versions of particular bits of code were used to process trade #12345. Can we see the source code for that version, log files from all of the systems the trade passed through, and records of any clock drift (to sync up the logs), etc. Oh, and that trade was from 1998...:(
The reason that Intel is side-stepping the P4 for dual core is because dual core (and blades, while we're at it) has one purpose... When big computing powerhouses were building "10 year" datacenters 5 years ago they assumed that the speed, power consumption, and cooling needs of servers couldn't continue to grow at the rate that they were forever. They were wrong, they grew faster (look at Moore's law mapped out over the last decade or so, the last 2-3 years are beating the curve but the wall is coming). Dual core is meant as a solution for companies who have maxed out their rack space, power, and cooling (virtually every company I know of and I work in a financial shop in NY with 6 digits worth of servers). Dual core is meant to stretch the life of that datacenter in all dimensions (space, power, and cooling) so that companies don't have to spend an (unbudgeted) small fortune to build new datacenters for a few more years. I think they're going to be pretty popular. Now if AMD could get their foot in the door (the techies pulled for opteron but we're buying Itanics now) I'd be happy.
Virtually every major JDK (Sun, IBM, et. al.) breaks when you move to an NPTL system because all of them pulled tricks with low level hooks into glibc and libpthread to try to up performance. This is the case with AS3 and with anyone else trying to implement NPTL at the moment. To my knowledge, neither Sun nor IBM have working JVMs yet, so none are in the beta.
well, since ac97 is probably one of the most basic sound drivers for linux and has been around for a long time you should try looking around a bit and figuring out what you actually have in your system (i have a via8233 that reports itself as an ac97 compatible chip but doesn't like the kernel drivers, it requires the alsa via82xx drivers to work properly). of course, this is kind of defeats the thread's point that sound configuration should be easy and automatic... hopefully now that alsa, et al. are making it into the kernel outright we should be seeing this in the future.
I work in the IT department of a major US University and, at least on our campus, these C/D letters have been popping up quite frequently lately. It appears that Sony (and maybe other major labels) must be running some sort of harvesting software that just searches for songs to which they hold copyrights, does a quick "whois", and mails off form letter style nasty grams to the contact listed. fyi, they look something like this (identifying info is X'd out, I like my job:)

Huge upgrade in the standard life of someone with an h1b visa.
we won't kick you out immediatly because the tech economy sucks... we'll give you ten days (anyone who's looking for a new job these days, please respond on the actual probability of this) to find a new job before we kick you out.
i'm an american citizen with an ivy league degree and +3 years (i'm only 21) of systems design experience and haven't found a decent offer in 2 months.
just looks like yet another opportunity to exploit these poor guys.
granted there are problems converting from the british system to the rest of the world (excluding the US) but nothing nearly like adding a few orders of magnitude... 10B pounds is about $15B, try a currency converter sometime.
Hmmm... beta release of Redhat (fisher) and a beta release of gnome, wonder why it doesn't work?
I'm running redhat 7 with 2.4.2 kernel and the beta gnome with no problems, maybe because redhat changed a lot of things in the fisher beta(including to a beta glibc if i'm not mistaken)?
in any case, don't expect to pile one beta on top of another and see it work. most betas have enough problems weeding out bugs with established systems let alone with other beta versions (anyone else see a perpetually recursive loop here?)
WebTV sucks becaue it involves a shitty ISP (now MSN if I am not confused by the recent series of buyouts) and TiVO runs Linux so it is better than beer:)
Games are a secondary idea for this box... Why would you possibly buy this if your primary focus was gamming when you could get an X-Box/ Dreamcast/PS2 for less money? This is something designed for much different pusposes (home entertainment - adding web access, digital recording/playback, and mp3 capabilities to your tv).
It's very possible that hackers will be buying the system to play with it... its also likely that moam and pop kind of deals will buy it to help wrap up a couple of devices into one. Nobody in their right mind willl look to this as a real "gaming machine", the games are only mentioned as a side benifit.
Read the features list...
If you can give me a Linux box with a 366, 64mb or RAM (granted those two are not too expensive), a 20 GB drive, and firewire, usb, tv and standard video outs to boot, all for $400 I'd be very impressed...
This might sound silly or even a little perverse to experienced computer users, but a new industry fad is to build what could be a decent PC and then cripple it to make sure it doesn't act like one. These hobbled machines often can't download or install software, or read e-mail attachments. Instead of Windows, they run operating systems from Linux, Be or some other company. These crippled machines are called Internet appliances, and they are billed as easy for beginners to use.
Not exactly a glowing representation of Linux.... while the machine itself sounds wonderful, the article is a real piece of junk, treating it like a piece of trash "because it doesn't run windows". Funny that they mention TiVO as one of its "more superior" competitors and don't mention that it too runs Linux.
Ah, well... somebody once said that "bad coverage was better than none at all" so I guess it is a small plus but it would be nice to see a better informed article on the machine.
it's a reasonable interpolation and speaking of your own comment...
>You could've come off as someone who was
>interested and wanted to know more. But no. You >had to make a snide ass remark. Good one, bucko, >we now all know what a dumbass you really are.
Because, as the article points out, this will likely establish new case law not because its mafia related but because the case will be put to test new means of surveilance for which no real law covers just yet.
IANAL, but that basically means that if this stands then the FBI/police can use the technology on just about anyone without any specific law ever being passed that gives them that particular right and it will stand up in court.
a very dead thread by this point but i was gone for a couple days...
true, 70ms is not a speed per se, but if you're communicating with someone in australia via a means that requires a lot of back and forth traffic, the latency becomes a big issue. if you're stuck waiting for a reply from a remote machine before sending out your next chunk of data (like say a result to a query of some sort) then latency adds up.
sorry that my intent wasn't made clear in the original post... granted latency isn't as much of a speed limit as bandwidth, but it does have an effect on the speed of many types of communication)
whats wrong with that? the majority of content still flows out of the US. 70 msec to get half-way around the globe ain't half bad. if every connection was this good, we could theoreticaly never have latencies higher than that.
they don't already do this... *CD only works with "participating" radio stations (i.e. the ones who provide some kind of "what song is playing now"). Just type in the station's call letters and it checks the current listings. Besides, you average Top 40 station keeps less than 100 songs in rotation at any given point in time, thats a far cry from "every piece of digitally recorded music that exists"
While he went through some bullshit from his own government initially, he eventually not only walked away from it all without any negative implications, the gov. (not the US, of course) gave him an award... (this was on slashdot and a few other news sites a few months back... looking for a link)
cause "User #230538" has been around for a long time... please flame about something you know anything about and we'll get back to you.
(i wish this was a day earlier and i could mod you to where you belong)
Slashdot Mirror
Nice idea, but "Failed: Invalid File" doesn't make the trial go so well... (NY/Cingular/Razr if it makes a difference).
