Ouch! I should've been more specific as I certainly couldn't afford spending that for my home systems. In fact, that would've cost *more* than 2 of the systems I'd have connected to it:p.
I wound up with a VGA+USB one from Iogear for about $110 including cables...
What I wanna know is where are the DVI-based KVM switches? I was recently in the market for one and couldn't find any. A 4-port DVI+USB would've been my ideal, but alas such a thing doesn't exist afaik and that's why I'm still using VGA.
Just to answer my own question - the tachometer doesn't "scale" like I thought it would, but a "10X" indicator appears if you exceed the initial "speed".
Coincidentally, I was working on setting up Sun Grid Engine on a couple of G5s here at work yesterday when I heard the news about XGrid. I dropped my work on SGE immediately.
It was a little confusing at first to set up, but I eventually got 3 machines total configured as part of my grid - 2x2GHz G5s + 1x867MHz G4. Perhaps if I read the instructions, I would've better understood some of the terminology (agent v. controller v. client, etc.).
The tachometer is sort of flaky. Sometimes it's stuck at zero on one machine while it it is actively moving around on others. Other times it's stuck at some non-zero position. Opening up 2 tachs on the same machine (XGridBlast has its own tach) will show different speeds. Though I should have in theory 8.867 GHz total speed, I could never get it to go over the default 8 "red line"- I was curious if it would rescale once it exceeded 8.
The XGrid client (where you submit jobs) has some default demo type things (I've mostly been testing the Mandelbrot one as it runs in a continuous loop), but it also has a way to build "custom plug-ins" which allow you to submit arbitrary jobs. In other words, executables don't have to be modified per se. Of course for any kind of parallel execution, they do, but if you need to to run 1000 iterations of the same command with slightly different arguments, then it should be able to distribute that "run" pretty well. The GUI for building up such a run is pretty easy to use.
One potentially big issue I've noticed is that once you submit a job, you have to keep the XGrid app open until it is done. For a run that may take days or weeks, I think this could be a problem. I'd like for you to be able to submit the job, quit, and log out (or shutdown the client even) then come back later to check your results.
Also, there doesn't seem to be a queue manager where you can see a list of jobs and their states.
I think that for any file-dependent commands, you need local copies of the files on each Agent node. At least that's how it appeared from perusing the documents for XGrid Blast - each node needs a copy of the database.
FWIW, we're using SGE successfully on a bunch of RedHat based servers, but though OSX maybe *nix, the installation and config was turning to be a pain.
Anyway, those are my initial impressions. I'm sure some of these things will change in the "release" version. In the meantime, I'll have to get working on getting some real work stuff to try out (I work in a university bio department).
Just wanted to point out another option if Clear Channel pop isn't your thing. Audio Lunchbox carries an interesting line up of indie label music, the file format is unencumbered, and songs are $.99. The have "bulk" rates, too, if you purchase a "lunch card".
I agree with the selection of Wipeout XL- I remember my heartrate picking up whenever Prodigy's Firestarter rotated in. That track made any race that much more intense.
Two more recent examples of the use of "singles" come to mind. The SSX series (SSX3 in particular, since its still fresh in my mind) pulls it off pretty well. The music matches thematically, and though it may not be music I normally listen to, the game is enriched by it (I tried turning it off, it felt a bit hollow).
Gran Turismo 3, on the other hand - ugh! I hated the music. The selection was too disparate. I turned it off. It was better.

This is my favorite show and I'm glad they brought it back to their regular schedule after a limited run early this spring. One thing people don't often mention is that it's the personality of the hosts that really make it. The subjects are interesting, especially to geeks, but Jamie (the one with the moustache) plays a perfect straight man to Adam's goofiness (best seen when they're both drunk in the breathalyzer segment).
Here's a link to their effects house's web site (not too much info, but some good pics of their facility) http://www.m5industries.com -h3
I have a workable system for myself as regards to passwords. Not a problem.
What *has* become a problem is remembering what login I used at various web sites. I usually prefer a certain 2-letter or 5-letter login, depending on the nature of the site. Some sites require 6 or more. Some require *8* or more. On a lot of *big* sites/services (think AIM or something like hotmail), my favored logins and various permutations have long been taken.
It's come to a point where I have more logins than passwords and when presented with a login screen, it's the login I can't remember- I know the password.
The trouble with logins, unlike passwords, is that they have to be unique on a given system, but you don't want random gibberish per se as they often function as 'screen names' or 'nicks'.
Aye, I nearly cried. I didn't realize until witnessing the ending just how much I had become involved with the characters- the ending evoked a complex mixture of sadness and joy. Yes, from a video game. When was the last time a movie did that?
Yes, they do. the apache parent process runs as root, sshd *always* runs as root, and so does postgresql.
Postgres does not run as root. Here's what happens if you try:
"root" execution of the PostgreSQL server is not permitted.
The server must be started under an unprivileged user id to prevent a possible system security compromise. See the documentation for more information on how to properly start the server.
I've been mulling over this issue myself lately. I know you mentioned iDVD as a requirement, but is that specifically iDVD, or "something easy and cheap compared to DVD Studio Pro"?
For me, it's the latter, and I don't need to burn on the road, so I've been thinking about getting something like LaCie's external unit, which comes with CaptyDVD bundled for a total of $299. I think the mechanism in the linked product is the new A06, but I could be wrong.
I've never used CaptyDVD and I haven't been able to find any substantive reviews on it, so maybe it's a dog. Or maybe it's great. Undoubtedly, it's not as powerful as DSP, but I would guess it holds it's own against iDVD as far as features go (and probably doesn't have some of the built-in limitations iDVD does).
So if a user's first post is "Hey everybody, I share your interest in foo. My stationary has unicorns on it. Hooray!". And the response is "Don't %$#'ing ever post binary attachments here again you %#$%'er!", then the user could easily decide Usenet is scary and rude and go back to the safety of their favorite web forum or mailing list
I'll be the first to admit that I don't know much about Windows and I'm no export on cryptography so maybe I'm an idiot for not having found a solution sooner. The big hurdle for me was that if I navigated to a site that used one of my own certs, IE would *offer* to add it permanently, walk me through the process, then congratulate me on successfully adding it. But it was all lies. It wasn't added.
As the document above describes (see the 12 step usage section near the middle) the solution I found to work is to convert my openssl CA cert to "DER" format, make that a downloadable file for IE users, and have them *download and open it*. With the proper mime type, this will trigger IE to walk you through exactly the same process as above, but this time it works, suggesting IE really only likes certs in a particular format. No excuse for making up lies, though.
Also, the way I set it up may not work for IE5, but I've had enough for one week:p. MacIE - hopeless. No way to import certs as far as I know.
From a personal standpoint, I couldn't care less how IE handles these certs since I don't use it, but I needed to find a solution that our users could handle.
WebDAV is supported as Web Folders in Windows, meaning there is no need to download and install SFTP, SCP, FTPS, and other clients. It's also supported natively in Mac OS X
Somethings to watch for: Windows 2000 SP2 had some issues with the mod_dav/mod_ssl combination we're running (uploads failed). Upgrading to SP3 fixed that problem.
Windows makes it a royal pain in the ass if you are planning on using self-signed certificates. I just couldn't figure out how to make IE accept self-signed CA certs. After literally years of seeking this information, I've finally found a solution this past week. This is something you have to consider for your users if you're going to use SSL with self-signed certs: how much can they take the constant popup cert warnings and how happy will they be about going through a 8 step process to get rid of it. Either way: poor user experience, which makes it hard for me to convince my users that DAV is a good thing (they're used to FTP).
OSX natively supports DAV but unless something has changed recently, it does NOT natively support DAV over SSL. You need Goliath for that. At least Goliath has a single "Accept this certificate permanently?" button that actually does what it advertises:p.
I have to say I feel your pain. I'm not trying to do something as ambitious as you (I just wanted something to replace FTP for users that wanted to share files with other users outside of our network), but I've still been frustrated with trying to get the authentication business worked out with different directories having different sets of users that can access them, some with read/write and some with read-only.
To be honest, I've recently started to re-evaluate using DAV for our needs. It just hasn't been as flexible as I had hoped.
Mea culpa, I only read the primary/first of the 5 articles linked:p.
This is good news! Part of my viewing experience was marred by fansubs of Chinese dubs, so the sooner I can shake that from my memory, the better. It just didn't sound right.
There was also a previous Initial D for the PSX ca 2000, also import only. Here's a link. It doesn't appear that there's any relation between that game and the current one, other than the obvious.
I got to try that one out briefly and was disoriented by the idea of racing during daylight. It didn't seem right as the races from the show were almost exclusively at night.
I learned a lot about cars from the Initial D anime, specifically about the performance strengths and weaknesses of various models popular with street racers when racing down montains. If you're into that kinda thing, it's quite riveting (conversely, if you're not, it must be the boringest thing in the world).
You can't help but cheer for Takumi and his humble Trueno (Corolla) emblazoned with a Fujiwara Tofu logo as it takes on Skylines, LanEvos, and RX7s.
Good stuff. Unfortunately, the anime series has never been picked up for release here- cultural differences? I don't know. You'd think they could've ridden the Fast and the Furious train. TokyoPop is translating the manga, but *reading* about hair-raising drifts doesn't seem quite the same to me.
If they every bring this game over here, I'd pick it up. In the meantime, I take out the Trueno in my Gran Turismo 3 (from which I learned the rest of what I know about cars) garage from time to time. Not quite the same, but I'm not half the driver Takumi is;).
I also don't see how this really relates to the OS used. As it states, 31 of the top 50 had no outages in the survey month, so the data ends up being sorted by %failed and response time, which I interpret to mean packet loss and ping time.
These are important metrics, to be sure, and I'm sure the OS used plays some small role, but I would imagine the network topology and the quality of the peering arrangements are much more significant factors here.
I think reading the docs and memorizing cryptic mouse movements is a bit too much to ask from the average IE user!
Oh, I don't know... they could have a paper clip appear and say "Did you know you can move your mouse up-up-down-down-left-left-right-right instead of pressing the back button?" in a thought balloon.
Followed by "To dismiss me, move your mouse around in a circle while pressing alt-ctrl-F12-F1".
With Perl I can use CPAN, load it right in, etc. With PHP I got to recompile PHP, and then recompile Apache. I haven't looked into PEAR but last time I looked it was still a headache
pear install some_package
This method has been in the default install as of 4.3 I believe. PEAR has been around a bit longer, of course.
"Starting at" is a buzzphrase that just shouldn't exist. Those wonderful G5 prices? That's for a barebones tower. What good is "up to" 8 GB of RAM when it costs you $2k to get the model with 256 MB? To get your system up to something worth bragging about, you're probably talking about a $3k machine in the end.
While I agree with your general sentiment, in this particular case it's not as bad as you might think. The G5s actually "start" at $1770 - you can chose to downgrade the SuperDrive to a combo drive and ditch the modem.
I don't know why Apple chose to call the $1999 model their starting point.

Hmm... if you drive this car and only this car for a long period of time, won't it be really dangerous for you to drive another car without this kind of compensation done for you?
Perhaps I overestimate the adjustment required but it seems to me like you'd be oversteering all over the place.
