And it makes tracing failure paths all that much more painful... each one is calling a generic function and now you're grepping through gobs of meta-data to even know the context of what you're looking at. Then you forget whom the caller was, trace back up, and find out that you've got recursive errors! Also, the overhead for constructing and tearing down frames every other call isn't exactly sexy; if you're crashing, at the very least, do it at a reasonable speed.
great, so now we're at 8 IPv6 sites, all of which are tunnel brokers!
Which, ironically, doesn't work well with NAT. That'll play out nicely when we're out of IPv4 addresses.
How many here think ISPs will try to use NAT to get around IPv4 exhaustion, effectively killing the very brokers we're trying to use as a means to avoid the very same problem?
Fortunately I've got about enough in my carpet to bolt down a full sized server board. I drop a screw, go looking for it, and come back with twice as many! On a related note, I always wear shoes when walking around my apartment.
I guess my Christmas present came late this year! I can't wait for this story on slashdot... it's like the ultimate flamebait because it just really happened and we've all been waiting for this headline for years! Gentlemen, I don't know about you, but today my karma is going to take a hit. A merry, albeit belated, Christmas to all!
If you get one that makes it to the end of the 90 warranty period, count yourself lucky!
This summer I needed a socket 478 (don't ask... broke college student) mobo, so I went down to the computer shop down town. I told the guy I needed a motherboard, any motherboard, cheap and before the end of the day. The guy says, "Well, we've got a few biostar for $50". There was a very awkward silence for about 10 seconds and I finally said, "Ummmm... got anything else?" "For $90 we've got one MSI left." "Sold." "Good choice; those biostar boards always come back to us." (or something to that effect)
I'd call OOo/Office2K a draw if they would only have some better support for freakin' pivot tables. At work we've got an in house Access app that I can subvert with an ODBC connection for reporting (say, JasperServer, openreports, crystal reports hack job with.NET for shooting-from-the-hip solutions, pick your poison), but nothing can quite replace the sheer simplicity of connecting with Excel and using a pivot table/report. I can whip up something with a few minutes notice that way, and OOo just doesn't integrate gracefully in this arena. To be fair, it's probably because they're stuck using a JDBC connection and translating SQL dialects, but, man... it's painful. I've never tried the OLAP support, but I'm thinking it's probably much of the same.
You can imprint with digital watermarks that can't be seen by the naked eye, but will show up on a screen shot if the watermarking app scans it (I've heard some can even pull the watermark off of a printed and rescanned image).
What I like about ask slashdot is that nobody is trying to sell anyone anything and there are enough knowledgeable people that the "you can fool some of the people all of the time and some of the people all of the time, but by no means both" rule applies. It's kinda' like peer review, except we all constantly bicker and are openly hostile... in other words, we're a bunch of geeks doing what we do best on the topics we know best. Did you ever notice how many people from the marketing department hanging around this joint? Exactly. And, all things being equal, the fanboys camps usually about equal out (I've seen Microsoft employees stand their ground here, on technical merit alone, against hordes of zealots on a few occasions) such that it's a zero sum game when politics come in to play.
Liar! You never had a genuine Hayes 2400 baud modem! You bought a knock-off, white box, ISA card of dubious origins with a speaker on it. You had a Hayes compatible 2400 baud modem like the rest of us, and you know it because you could probably recite the connection string that you needed to get it to work at "full speed" (read: 'bout 2kbit).
Did you run sensors-detect, load the kernel modules, and then sensors -s? I always forget the sensors -s call which sets the sensors that sensors-detect found...
If you're using ext2/3/(4?), 5% of the file system is reserved for root by default. You can pass "-m %" (where '%' is the percentage of the file system you want to reserve) to the mkfs command to set the reserve. Although I usually try to leave 1%; it sucks to fill the drive and not have enough free space to delete anything!
So they finally got around to adding those much anticipated checksum and sign bits, eh? Hopefully someone told the marketers at the telcos that they can stop stealing frames from the trunk lines! They're honest, though; they include those bits as part your bandwidth... they don't just round them off like the hard drive manufacturers do.
Surely you're exaggerating... sounds like it was less of a disaster and more of a train wreck! I'm conservative (US conservative, not sure where that falls on the Australian political spectrum) and reading that made me cringe!
As a college student, the largest problem I have with politically active 'organizers' is that they want to be involved with politics. Regardless of where they fall on their political leanings, they all have this in common. I think ego is part of the package. The other part is the absolute inability to accomplish much. The talk always goes something like this:
"So, what, you're organizing a rally?" "Yeah, we've got a band and everything!" "So, did you write a speech or something, invite a well known speaker?" "Well, no... but we did get a band! It's gonna' rock. See you there?" "Yeah. Sure. I'm clearing my calendar as soon as I get home."
It's like open source, it's all well and good to discuss the ideals of it, but it's much more effective to just shut up and write some code or donate to a project.
Well, I get high throughput with my NIC drivers that poll (I can't remember the kernel compile option for this ATM), but this is at the cost of a higher latency. The trade off is that I've got 5 NICs on this box and it turns out that without polling I get close to having an interrupt storm and spend all my time switching context to execute the drivers bottom half of the interrupt. With polling, the interrupt gets masked and I don't have to worry about servicing every interrupt coming down the line. My latency is higher, but I get more throughput for every time I service the bus as it has more packets to process. This also means I'm trading off space for time (I need larger ring buffers to queue packets) such that I have less memory for the system, but processes get more time on the processor between interrupts.
While not having to do with USB, the driver architect and concepts are likely very much the same.
No doubt, even without a TOC or any kind of analysis other than a raw disk dump, the fact that the thing had structure should have been the first clue.
I used to do the audio booth at my church for live concerts and the such, and those direct to disk recorders are a pain (or at least the one we used). If you pause them and then try to start them again while they're closing the track, or something to that effect, sometimes they'll merge tracks or not close at all - but the stream is always there, if somewhat incoherent.
I regularly forget/neglect to close my audio and data disks and I've found that free-as-in-beer/donationware 'ISOBuster' always does the trick (or 'dd'/'ddrescue', I've pulled data from a scrambled reiserfs before this way, I'd wager it'd work for ISOs, too). At any rate, this task should not have been a challenge for even a freshman CS student with some free tools and an hour to kill.
FWIW, I'm in Kutztown, PA (I'm a student at Kutztown University, home of the first google satellite image:) ). Just outside of Amish country. We've got cornfields everywhere (I'm about 10 feet from one at my apartment), and a few times a week you'll be stuck behind a horse and buggy on main street.
The stats:
town size: 1.5 square miles
population: 5000 + 1800 students living in town('cept I think I'm the only one who sticks around for summer - the town is paradise!) + 8000 students on campus
... Oh, yeah, and we've got the entire town rigged with fiber, a six point bus topology backbone of multi strand fiber which branches off to each house. Also, automatic utility metering/monitoring, digital HDTV, VOIP, security, and wifi hotspots run over it. BTW, run by our local town government's created company, hometown utilicom. Fiber, 2mbit down/128k up, $25, 3mbit/3mbit $80, and take a cut off of that if you're a student or buy a phone/internet/tv package. Free digital HDTV with basic service, etc. They do web hosting, too. I'm sure you see what I'm getting at here. It's not just doable, it's being done and the service is exceptional.
The best part is that the town put up fiber because none of the local telcos would provide service... now they're climbing over each other to get to our last mile. So much so that they lobbied for laws to be passed to make sure that towns can't do this kind of thing. Kutztown was grandfathered in after the law passed and now towns have to give the telcos 18 months to service them before they start their own projects.
BTW, the entire infrastructure was paid for with 30 year bonds. We even generate our own electricity, too. Since the town provides everything the town needs and the community pays a reasonable price for it (economies of scale and all that), taxes haven't been raised in 70 years. Checking the link for hometownu, it appears they're testing 5/8mbit. Love this friggin' town!

No, don't you know that a website doesn't work if it doesn't have the magical www in front of it? [...]
(yes, I had someone tell me that as I was trying to get a site up... *sigh*)
Please tell me you gave the shoulder surfing PHB/luser a proper thrashing with either a LART or a clueByFour. Twice.
Otherwise we'll be revoking your nick; I'm sure you understand.
Killer drop in on the comma splice there, champ!
NOOO! Anything but Biostar! Seriously.

USB 2.0 gave us high-speed and full-speed. Some marketing department had to work really hard on the USB 3.0 specs, to come up with... super-speed.
I'm holding out for WARP speed...
I'm holding out for plaid speed...

Well, when you consider that being smart is rewarded with neither babes nor cash, entertainment doesn't seem so bad.
You make me feel like a third wheel!
You're sick.
