Comment Re:KVM for maintenance (Score 1) 277

>RDP and VNC aren't much help if that server is waiting in the bios to tell you a SCSI disk is offline.

You can set up a gateway VM (or physical machine) on the same local network and RDP to that, then connect to your iLO/DRAC/IPMI/KVM. The bandwidth-intensive KVM will stay on the same network, and you can use a lower-bandwidth protocol like RDP to connect to the gateway machine.

Many places use this as a security measure - users from the VPN are only allowed to RDP/SSH to the gateway machine, then access internal systems from there. It makes it easy to firewall off systems from the outside.

>Yes it is, If you knew anything AT ALL about computers or electronics you would know that. Go look up how audio pathways work in a computer kid.

Two computers sitting in the same room, with both speakers and microphones, could easily communicate by emulating a 300 baud half-duplex modem, for example.

For even lower bit rates, use something like DTMF tones.

What is it that you find implausible about computers using sound to communicate, considering we've been doing it for decades?

> I do not know if that would be faster/better to do 'join' statement over multiple huge data tables compared to nested queries.

Yes. Someone who is writing SQL queries for a living should already know that, so asking him to rewrite it using JOIN would be useless unless it's an entry-level job, because he isn't going to get hired.

You're right in that asking people "why did you do it that way?" is a good way to find out if they understand what they are doing, but it should be asked open-ended like that at first, so that the candidate can demonstrate their knowledge. If you don't get a good answer, then ask "why didn't you use JOIN?".

>Also, why would GET & POST requests be involved in security?

GET parameters go in the URL and may be logged inadvertently or captured via Javascript. Search engines and browser pre-caching may trigger GET requests accidentally, so having a 'delete' action be a GET request, for example, would be bad.

More to the point, anyone in an internet security job should know this, because it's a building block to understanding more complex things. The candidate should understand the HTTP protocol thoroughly. If they don't know GET vs POST, they certainly don't know any advanced concepts that the job requires.

Comment Re:money? (Score 1) 810

IRS mileage rate for 2013 is 56.5 cents per mile, so 500 miles would be $282.50.

Subtract the cost of gas (US new car average of 24.9 mpg, so 20.08 gallons @ $3.269 US average = $65.64) and you're left with $216.86 as the cost of operating a car for a 500 mile trip.

The IRS rates are high, you say. This calculator says between $0.15 - $0.30 per mile for wear and tear. Let's use the low figure, $0.15, which gives us 500 x $0.15 = $75.

Note that "wear and tear" includes depreciation, because the more miles you drive, the lower the car is worth. A 2002 car with 20,000 miles is worth more than the same car with 200,000 miles. It also includes tires, brakes, oil, timing belts, etc because the more you drive, the more often you have to change these things.

Many people don't count those as per-mile costs, and instead act like a new clutch or timing belt is a total surprise, instead of an expected result after so many miles of driving. However, they are valid per-mile costs, and if you budget appropriately, you likely won't ever have $1,000 surprise repairs - you'll just have expected repairs.

So if it costs the rental car company $75 and they charge you $50, how do they make money? Well, it doesn't cost *them* $75.. they have their own mechanics to do oil changes, brakes, tires, etc, and they get bulk rates on parts and fluids.

http://en.wikipedia.org/wiki/Double_negative#Slavic_languages

In Slavic languages other than Slavonic, multiple negatives are grammatically correct ways to express negation, and a single negative is often incorrect [...] For example, in Serbian, Niko nikada nigde nita nije uradio ("Nobody never did not do nothing nowhere") means "Nobody has ever done anything, anywhere", and Nisam tamo nikad ila ("Never I did not go there") means "I have never been there".

So what you're saying is that the department can outsource 75-80% of its staff, while keeping a few people on site.

Comment Re:Why do I need an aggregator? (Score 1) 335

Using it with 40 different blogs that all post the same shit is silly. Don't do that. RSS is supposed to be used with irregularly and infrequently updated content.

For example, I use RSS to keep up with web comics. Now I don't have to remember that Comic A updates on Mondays, Wednesdays, and Fridays, and Comic B updates every 3rd Thursday, and Comic C was on hiatus for a summer but started up again. I just go to my "comics" folder on Google Reader and see what's new.

I also use RSS to keep up with a few low-volume blogs, that update whenever the author feels like it, but general 2-3 times a month.

There's no good replacement for RSS.

Or what I've seen some routers do, intercept any and all web traffic and redirect it to the router config page until the router is configured.

Comment Re:Multi site sync (Score 1) 302

Rsync would also work, but BitTorrent will be faster.

> a half dozen locations that have as much outbound bandwidth as the primary

Assume all the sites have 10 MB/s inbound and outbound. To transfer 3.7 TB (3,879,731 MB) would take 107 hours per site, 646 hours total.

Using BitTorrent, all 6 sites will take somewhere between 107 and 646 hours - probably around 300 hours, because after one site receives a block, it can send it to the other sites, without using the primary's bandwidth.

The daily diffs will of course be smaller - but the same principle applies. BitTorrent will also verify the existing data and then just transfer the new bits, same as rsync.

Not so - your collection of games under Steam/Origin, your music/TV/movie collection under iTunes/Amazon/Google Play, and other 'licensed' digital items belong to the person who just died and can't be transferred. Legally, you're supposed to wipe those items from the drive.
