You missed the parents point about security of the logs. If a hacker gets on a system with a text log it is trivial for them to change that log to cover their tracks.
No, he said he feeds the logs to serial - that is, they get recorded on a separate system. You'd have to compromise two systems to cover your tracks on the first, oh, but then a third, etc.
I'm not sure I believe in 'tamper proof' logs on a system where you have root.
Wndr 3800 (not 3700) if you're buying online. There are some versions of 3700 you don't want, and it's almost impossible to know what version you're buying online. The 3800 currently only has one version, which is supported in the current trunk of OpenWRT.
I ordered from Amazon both new for the office and refurbished for home, and I got 3700v2 for both.
I think it's a matter of who has old inventory vs. high turn-over (though I guess refurbished could be a crapshoot). But the refurb 3700 is half the price of a 3800.
You missed a requirement: in a form that's still usable when the machine keeps going down hard in the middle of a boot. 'tail messages' still works, nothing to get corrupted or worry about a write-ahead log that can't get consistent.
Not that I spent the day today troubleshooting one of those or anything...
So, the standard technology adoption catch-22. Almost nobody uses it because it's expensive, and it's expensive because almost nobody uses it.
Which basically drives at the fact that it's optimizing something that doesn't really matter enough.
Real estate, infrastructure, and bandwidth are much more expensive, in comparison, per U, than electricity. If electric costs go up, people will probably care more about electric costs.
Isn't it possible that this is because Apple and others trained the average user to believe that?
But what incentive would they have to do that? It's not like instead of importing a HyperCard stack, people are going to plunk down $3.99 for equivalent apps by the billions and Apple is going to take 30% of that.
Yeah, I've never quite figured out why telecoms have standardized on 48VDC while everyone else completely ignores its existence.
I went through this with a client. There was a 'green' data center opening up an hour north of them that insisted on all-DC gear. They charged per-Amp, all you can eat data and rack were included.
We spend probably 20 hours spec'ing an all-DC set of servers, switches, firewalls, smart-PDU's, serial consoles, etc.
By time we were done, the cost of all that DC gear was 1.5x the cost of the COTS AC gear, and that difference paid for almost two years of standard colo outside Boston. Plus we could get onsite service contracts on all of the AC gear.
Exactly right. The Google application is either negligent in its research duties (which is inexcusable since Slashcode is open source) or the applicants have perjured themselves.
The uneducated immigrants, all media hyperbole aside, take jobs Americans don't.
I live in an area with few to no Mexican workers and Americans do all the jobs. Cleaning, lawn mowing, farming, etc.
It's simply that in areas where the Mexicans are, employers can hire employees who are not burdened with the cost of Big Government, so Americans who want to remain law-abiding can't compete.
(And yes, the Amazon version was noticiably blurrier as it was scaled up to the screen, whilst the Tablet was scaling down a higher-quality stream).
I think the HD stream is encoded with a higher bitrate (per pixel), and perhaps the Amazon scaler is crap. The HD/SD distinction isn't so much about resolution.
Good SD video with competent upscaling ought to be plenty for a 7" screen. I watched a few DS9 episodes on my Nook Color (CM7 w/Netflix) and there was quite a bit of block aritfacting and quantization noise (and... buffering delays). Playing a DVD-ripped AVI (mplayer IIRC) looked great.
That's perfect for the wipe, but he also needs backup.
PXE boot to pxelinux for a nice menu, then choose the backup (e.g. Clonezilla), throw a sticky note on the computer to indicate state, then reboot after the backup and choose DBAN.
A clever setup would keep track of which machine is in which state and hand out DHCP options accordingly, making the menu unnecessary.
With that many computers, backing up the drives to a ZFS volume with deduplication enabled is probably worthwhile (but make sure you have at least a GB of RAM per TB of disk).
Then the problem isn't just pulling information, it's matching some signature of the disc to that information and building that database of disc signatures.
Right, which is what CDDB, FreeDB, et. al. do. There must be some reason this has never happened for DVD's. One factor may be that CDDB existed before DMCA.
But I have sacrificed and risked my career and a lot of money to get to this far and I can still fail, but in my mind that is not an option.
No, no, you were just very lucky - hard work and sacrifice were just coincidental.
The things I have learned are priceless and the experience is VERY rewarding. Oh yeah, it isn't all about the money, my dream is one of helping people and being a service to mankind in the ways that I can.
Can't be - if you own a business all you care about is GREED!
I think that if I do a good job at this then I will be rewarded with money as well.
Hey, that's *our* money - we should take it from you by force!
(sorry to pick on you with echos of the hive-mind - you're just a great example of what capitalism is really about and I hope people can see Poe's Law in my comments)
The nose would open up and the incoming passenger module would slide out to be replaced by another outgoing module.
And you load up the passenger compartments with giant parachutes and floats, so when the plane's engines get blown off or the venturi tubes get iced up and the plane is headed straight down into the ocean at 10,000 fpm, you sacrifice the plane but save the passenger compartment.
At this point, airline accountants start crunching wrongful death outlay numbers and comparing it to the cost of a semi-controlled landing and the odds of saving the plane...
Heck, I'd probably accept a DHS red-button to force a scuttle, if I thought it would get the idea finally implemented.
... but unfortunately that doesn't stop individual Sith Senators from trying to use their influence to curb free speech.
Ironically, some of his speeches on Iran would probably have to be censored if he had his way. I guess YouTube already won't host his Beach Boys parody, BOMB-BOMB-BOMB BOMB-BOMB-IRAN.
TLS 1.1 may be excellent, but Google recently added support for perfect forward secrecy to OpenSSL, which would seem like a nice feature to have for governments. If they're sending secrets over OpenVPN with standard TLS, those secrets will only be secrets until computers are powerful enough to factor the primes used to negotiate the session. That might only be a decade - hard to say.
This led to the use of the wire-suspended camera for most kicking plays.
Oh, that's really a camera over the field? I assumed they had a few hundred little cameras around the field and some compositing software so they could follow whatever shot they wanted to. Wrong decade, maybe.
... What exactly does this have to do with the older pentium architechtures?
The current Intel line of decent chips is descended from the Pentium III line. While the marketing department was running the US operation with its Pentium 4 ("burn baby burn") line, a small group in Israel took the Pentium III and made it power efficient ('Core').
Pentium 350 sounds like the end of Atom. Yay, I guess, since they handicapped Atom on purpose.
Now throw in a team dedicated to information security and you get additional opinions on how to do patching. Its next to impossible to put 10 people in room and get a decision, and these conversations go on for years.
If that's the case, they're not a team dedicated to information security, they're dedicated to having easy jobs and like to call themselves 'information security professionals'.
Often times the grounds are bad, the phases are wrong, the polarity is reversed, etc. A good EE should be able to make a circuit that deals with these common problems, but probably the work for the design they're deploying was hired out to a low-bidder overseas. To "save money".
If the "smart meters" used cellular tech they would not have to drive down the street, but let the meter call home and report.
Most of them that I've read about use powerline IP to communicate back. Y'know, over the millions of miles of network the power company already owns.
I'd probably rather have a wireless one, though. The "beauty" of the powerline IP ones is that they have realtime access to them. So, the power company can:
know when your power is out without you having to call
read the meters without dispatching a tech and saving that cost
know what your personal habits are and sell that data to marketing company (many types of electrical gear have unique signatures)
know in realtime when you get home from work and sell that information to telemarketers who can then only bother calling you when you're home
sniff data off your own powerline networking gear and feed that to the NSA
watch for 'suspicious' power patterns and feed that to the DEA
know if you've got an extra human living in your house and notify the local authorities
All with the benefits of being run by a highly-regulated utility with a monopoly grant. Gimme a wireless one that I can just shield from the direction of propagation I care about any day.

Why not stay within DNS? Delegate queries to a subdomain if it gets huge?

The new Nook tablet comes with a locked bootloader, unike the Nook touch.
Does it still boot from MicroSD? I'm happy to wipe the internal memory and put CM9 on it anyway.

Gamma International sells computer hacking services to governments, offering 'zero day' security flaws
These are the real blackhats - most 'hackers' don't sell their services to get people killed. Legalized blackhats, perhaps, but blackhats nonetheless.
