You're stupid, for not appropriately using RAID5
on
What NAS To Buy?
·
· Score: 4, Interesting
As a person who's suffered a RAID-5 failure and dealt with the poor performance I can say that RAID-10 is significantly better performance and significantly better reliability that is well worth it.
RAID is just a reliability mechanism. It's not backups. Any NAS solution you look at should have a way to back up part of it, and many do.
RAID5 is acceptable IF you regularly scrub the array AND you don't have too many devices in the RAID set, because it is designed to tolerate one disk failure. RAID6 in a 4-5 drive configuration should be plenty safe in quantities most people would use for home NAS's.
RAID10 does offer much better performance, but the performance increase would be largely wasted in the home market. If you're watching video, anything over a couple megabytes a second just helps with seek performance (802.11N is just about perfect for most movie and TV "rips", for example- 802.11g is doable), and when you're uploading or downloading media, anything beyond the speed of local disk is also pointless.
They recently bumped up service to a full megabit upload speed, mostly because of Verizon FiOS service (which still isn't available anywhere in MA except the rich white suburbs- Boston's completely "dark", yet surrounded by towns and cities which have it.) However, if you use it past the old limit (384kbit), after a few minutes, latency skyrockets.
It takes anywhere from a minute to several minutes to kick in, but when it does, ping times to google jumped from 20-30ms to over 300ms. Sometimes I found ping times would be *seconds* long, and ssh became almost completely unresponsive. Curiously, none of the packets would actually be dropped- they'd just very, very badly delayed.
Seems very clearly designed to a)look the same as Verizon "on paper", 2)Satisfy people who want to email photos of the kids to grandma and grandpa (I will admit, it's insanely nice to be able to upload at four times the speed, when it works).
I loved reading it too, so I was very disappointed to read that it was ghostwritten. It was ghostwritten by a close friend who worked with him on the book, but it was still ghostwritten...
...and if it's serious enough to impact your long-term health, you should get those "hormonal/glandular issues" looked at. If the doctor says, "there's nothing we can do about it", fine...
My ISP is at a loss as to how to fix this but it is causing me a lot of grief.
What grief? The only 'grief' you've elaborated on is being shown ads (which most everyone on slashdot probably blocks or ignores anyway) in French. That hardly seems tangible. Can you elaborate in a comment, please?
You didn't even respect me enough to run it through a spell-checker
Neither did our illustrious Studio Head. There were numerous spelling and grammatical errors, and he occasionally slipped into the deeply irritating BlackBerry Shorthand.
Worse still, our "editors" didn't bother to proofread it either!
Comcast recently announced they bumped upstream bandwidth from 384kbit to 1mbit (FiOS pressure, anyone?) and they've also said they won't monkey about with p2p, right?
Well, funny thing then that when my bittorrent client inched above 45-50kB/sec (less than half of the new limit, which is 125kB/sec), shortly thereafter ping times exploded from 20-25ms to 300-500ms. On a second occasion, it went up to 1000ms to 3000ms. Even if you throttle back to, say, 20kB/sec, ping times stay the same. They don't drop until you stop the client completely. Seems to take about 10 minutes for the throttling to kick in. It's so bad that ssh latency goes up to 5-10 seconds, and the web interface to my p2p client completely stopped working.
The same thing happened with eDonkey, so either they're going off traffic volume, or they're detecting any p2p traffic.
I recently had the opportunity to see, first hand, HP's new 30-bit, 1 billion color LCD display. I have to say I am impressed.
This doesn't get you much unless the display also has a wide dynamic range- and it doesn't, it's 1000:1, which is pretty average (ratios range from 700:1 to 2000:1 in Dell's lineup, for example.) Ie, keep the same 'color resolution' (which is useless past the eye/brain recognition point) and make the gamut and DR larger.
I especially don't see why the submitter is "impressed", since he/she hasn't seen it in person- only marketing photos (at, ahem, 24 bit color) showing the new display with its brightness cranked up.
Attach a bunch of printed gay pornography to your next court submission and see how much the judge likes it.
The judge will most likely never see it. Assuming it isn't intercepted by a clerk, it will get as far as one of the magistrates, who does 90% of the work these days in the courts- the judges mostly supervise and sign off on the magistrate decisions. Kind of scary...
Cory Doctorow took what would have been a one-line slashdot troll ("imagine the day when the cops or Manufacturers Industry Alliance arrest you for making counterfeit stuff") and turned it into a badly written sci-fi short story.
"Craphound", indeed.
with a long string of production successes on his resume.
I'm sorry, but someone who has ONE major hit in his entire career is not someone you look to for advice on 'breaking into the movie business.' He was executive producer on Sling Blade- more than ten years ago. The rest is made-for-TV stuff and 15 minute shorts. Another shining star on his resume: a 2009 remake of The Saint. Yeah, that movie with Val Kilmer. That would make it the second remake of the 1962 film...
They might have had to lay off 200 employees. Out of TWO THOUSAND. Because their budget was "slashed" by just 22M (less than 10% of the budget.) Christ. It's not embarrassing, and the lab was in no danger of being "lost."
It's also still unable to seek properly in a lot of mkv files, and doesn't support their chapter functionality.
I stopped using it on OSX when Perian (ie Quicktime Player) started supporting MKV (including chapters), subtitles (including styled ones!), etc. It's become my strong preference.
Yeah, but what if Google decides that nobody is using these -- or they can't legally host them for whatever reason -- or they just decide that they don't want to do this anymore?
Think broader. What happens when:
Google decides to wrap more than just the promised functionality into it? For example, maybe "display a button" turns into "display a button and report usage stats"?
Google gets hacked and malicious Javascript is included?
But, yes- you're right. This is a scary new dependency. For a company full of PhD geniuses supposedly Doing No Evil, nobody at Google seems to understand how dangerous they are to the health of the web. In fact, I'd suggest they do, and they don't care- because they seem hell-bent on making everything on the web touch/use/rely upon Google in some way. This is no exception.
A lot of folks don't even realize how Google is slowly weaning open-source projects into relying on them, too (with Google Summer of Code.)
I own one, and the "keyboard" is a bitch, especially in portrait mode, which is the mode you're stuck with in almost every application save "Safari". You can't use the larger landscape keyboard in SMS, Notepad, Email, etc.
The error rate is high because (big fuckin' surprise, just like everyone predicted) there's no tactile response. There's no caps lock or sticky shift. Only alpha characters are on the main keyboard; you have to go into sub-keyboards, and there's no way to return automatically after typing one punctuation letter. My Nokia 6820 had most of this down perfect.
This: "/etc/init.d/http restart" would take forever (each / and . would take three taps), and because of the error rate, you'd run the risk of triggering an account lock or ssh abuse prevention IP block just trying to get into your machine. God help you if your password is actually secure (ie alpha AND numeric with some punctuation or case changes.)
Sorry. No "real" QWERTY keyboard automatically disqualifies any device.
Like this, which are designed to keep you off a network unless your system is up to date with all major OS patches, and has antivirus software with current definitions?
If it's a waste of money to spend effort on keeping up with patches and antivirus software/definitions, I think it'd be hard to argue for spending money on systems which enforce hard-line policies (thus not only "wasting" IT's time, supposedly- but now also wasting employee time as they can't work until things are fixed.)
Sometimes items are redacted because of contractual commitments or confidentiality agreements. [...] But hey, they made their point about evil government masterminds being wholly incompetent, so what does logic matter?
Please explain the logic behind the government agreeing to confidentiality in a business transaction where taxpayer money is involved?
Negroponte said the foundation hopes that the cost of the new device, which is scheduled for production by 2010, can be kept to $75
Is that 75 Real Dollars, or $75 Negroponte Distortion Field Dollars? And it'd be nice if the press actually took a stab at how realistic those "hopes" are- I mean, I hope that someday I'll shit strawberry-flavored lollipops while driving in my flying car, on autopilot while I bonk my supermodel wife...
The UI is still an utter disaster. At least it looks like they finally improved the documentation for the mac platform - I once spent an hour trying to find out which modifier keys corresponded to which blender meta-keys, and how to get various buttons on a dual-button system.
The Blender team, unfortunately, is driven exclusively by the concerns of users who are experts in the field, not beginners. If I didn't know better, I would attribute the reluctance to even CONSIDER modernizing the UI (which looks straight out of 1980's autocad, for fuck's sakes) to two words: "job security."
It's a shame, as there are a lot of folks who would love to fool around with it and learn it...but when it took me two hours just to figure out how to render a JPG of a box on a damn checkerboard floor, no thanks.

Without him, I am not sure that personal technology would have taken off,
No. Chances are that we'd simply have a different guy filling his shoes, or a different company filling Microsoft's.
For example, maybe we'd all be using Sun computers...

The Washington Post has not, would not, and never will boycott the AP.
They also wouldn't say "ban", where "boycott" is the proper word.
There's a big need to fix testosterone-fueled code at Ingres
There's a big need to stamp out the bullshit myth of testosterone poisoning, perpetuated by feminists hellbent on knocking men down at every opportunity.
It's precisely why I don't support most 'feminist' causes these days; they're too busy screaming about how much goddamn better they are than men.

Because unlike a lot of other slashdot posters, I don't immediately assume everyone around me is dumber than I am.
It was an OBVIOUS joke.
