My understanding of a hot backup is a mirrored db that can take over if-and-when the other stops responding. I'm not saying you can't back your data up (that would be rediculous), but pg_dumpall isn't enough for a hot backup. For instance, it takes quite a while to dump the DBs because every record is pushed out. In a hot backup system, you dump once and then syncronize the differences. This keeps you up to date in (near) real time.
As I said, there is work ongoing to add this functionality as a separate module (IMO, a good idea, because not everyone will need this), but it's only alpha quality right now.
I agree that postgres is a good solid DB, but it still doesn't have good high availiability features. For example, there's no replication or hot backup stuff, except for some alpha quality things.
Once high availability is added, though, it will be a serious contender in enterprise designs.

First of all, if ANY single host starts slamming my site with HTTP requests, I'll instantly assume that its a DOS attack.
But that doesn't help with a/.ing. Many hosts making a few requests is the cause of the site bogging down.
I don't think proper configuration is enough to withstand ~10000 simultaneous requests. While using a throttling http server like thttpd may help, I doubt even that is enough.
I have a game console which uses CDs. Can I copy these CDs with CloneCD?
Sure you can copy them! But the question should be - will they work? And the answer is: No. CloneCD does not disable the boot protection found on console CDs. As we already said, CloneCD does not modify the data it reads or writes in any way.
However, if you have modified your game console already to accept backup copies, copies created by CloneCD will work. There is even a nice side effect: Almost any *additional* copy protection (apart from the boot protection) will be copied, too. Backup copies created with CloneCD will therefore work better than copies created by a different program. However, CloneCD was designed to make Safety Backups of PC-CDs, not for game console CDs.
It still appears to me that there is extra protection in addition to the errors you describe, and this is what the mod chips disable. The same is true for DVD based systems AFAIK.
Hmmm. I'd have to see one of these work. My understanding is that the original discs have something on them that regular discs don't have. In this way original playstation or xbox discs aren't any kind of standard (on purpose), so this machine would have to be tooled specifically to make these discs. It's not a matter of burners not being able to make copies of the data (they can make them perfectly fine, as evedenced by the fact that backups work on a modded console), but that the discs have something special that the console checks for, probably outside of the data range.
It comes down to assurance of quality. Downloading off of Kazaa can be a real let down and for files of this size can also take several days (because the people who have them sign on and off). I live a block and a helf away from a Blockbuster, so maybe I should say *for me* it's more convinent, but I'm not the only one I know who prefers this method: my exroomate (at a different place very far from a blockbuster) would rent about 20 games at a time and then copy them and return them the next day. Maybe downloading 1 ISO is easier, but 20 is a pain.
A funny story: the another roomate in the same place was into ISOs on IRC. Someone in the channel had a rare Japanese market game ISO. My roomate asked the guy what he wanted. The roomate then copied his windows swap file to whatever.iso (where whatever was the name of the game the guy wanted). They then swapped "ISOs". A day later our firewall was DOSsed. We figure the guy didn't take too kindly to the trade:)
Xboxes, like other disc based consoles, check the discs they run to make sure they aren't pirated copies. Otherwide, anyone with a DVD-RW could make a copy from a local Blockbuster (or download an ISO off the net but blockbuster is more convinient). Unfortunately, this means that programs that you make and burn to disc won't run because it won't pass the check.
Mods remove the copy checking so that you can run backed up or copied discs.
Luckily setup.exe is very small. Cygwin's setup.exe is analagous to Debian's dselect and part of apt, although easier to use. It connects to a remote host to find out what packages are available and you then use it to select packages and their versions. Once you've done that, it'll download and install, update, reverse update (if you want to go to a past version), and remove packages according to how you set it up. It also does dependancy checking (for example, I added Windowmaker and it added all the xfree stuff). Definitely a neat utility.
Most phones have a jack that you can plug an earpiece/microphone into, and come with such a device. I know that when I used mine, I had a dramatic increase in my ability to hear and people's ability to understand me.
As funny as that is, I used to work on a system that has 128 bytes of RAM (yes bytes, including stack). However, it had 128K ROM for code and lookup tables in the initial spec and was changed to 256K when it was realized that 128K wasn't enough. This was in 1994.
The processor didn't have mul or div either. I had to write those routines.
I'm one of the people who thinks that because deep linking is a configurable option, that it shouldn't be made illegal.
First your analogy. The fact is that we can't make a house 100% burglar proof without making it inaccessable to the owner. Even getting it to 5 9s would require a lot of cost.
On the other hand, setting your webserver to not allow external referrers is quick and cheap, much cheaper than it would cost the state to prosecute each deep linking offender. This is a big sticking point for me, because I really don't understand why we should spend thousands of dollars on the court system to support a $5 change in configuration (ok, maybe ~$40 if the sysadmin doesn't know how to do it).
There is also a difference in the scenario that you describe and what is going on here. Say you had a house and invited people to come in and look around with a big sign viewable from he highway saying "come into my house". You leave the back door and the side door wide open and in the kitchen have a small plaque "I only want people to come in the front door". Then you sue your neighbour for pointing out the side door.
Even this analogy sucks, because analogies always suck. It always better to talk about the thing at hand. The thing at hand is that people are putting up a public website that they want people to come to, and they want to waste goverenment money where a little expnse would solve the problem.
Bear also in mind that if you don't put lock your door, then it's not illegal for someone to come into your house, thus the "breaking" part of "breaking and entering". It's only trespassing until you tell them to leave and they don't. And if they steal stuff, that falls under a different law.
Ok. This makes sense to me now. If there are several unpatented algorithms that have equivelent features as yours, then you shouldn't bother patenting them, since it will just encourage noone to adopt it over the well known unencumbered ones.
Even though RSA wasn't the first assymetric-authenticating key systems (Diffie-Hellman was before it), all other assymetric key systems were also patented, so it worked well. Now with several such systems unencumbered releasing a new encumbered one wouldn't work out well.
This is probably true for things other than encryption. A widget that acts exactly like another without a patent probably won't do well if all other things are equal. Buut with encryption, as you say, you need adoption for credibility which leads to adoption.
That would make sense if RSA hadn't patented their algorithm. True the patent has run out, but there were 6 years that I was waiting for it to happen. Since then, that patent helped them create a well respected security company.
yeah, you are right. I didn't really use the right word there. He was diagnosed with it. Maybe in err, there was a feeling that he didn't develop an understanding of numbers because I was doing his homework, but it could have easily been the opposite (he didn't have an understanding of numbers so he got me to do it).
My understanding is that a stroke or other brain traume can have you become dyslexic. It would probably suck, but strokes are rarely fun.
This is somthing I considered doing when I have shrubs. When I was a kid, my (older) brother got me to do his math homework and ever since then I always had a leg up on math. I kind of want to simulate that with my kid(s) without getting an older one to pawn off homework (he, incidentally, became dyslexic with numbers and had to go to sylvan learning school to help correct it).
One site I like to visit is grey labyrinth. They semi-regularily put up new puzzles and a lot of them use some applied math. Not really a whole solution, but something to look over and point you in a few areas of math you can research on the net (like probability, induction, and others).

I'm sorry, but aquisition isn't as good as having an already established brand and manufacturing site(s). There are many things that go with aquisition that can impact how you enter into a market. You had better pad the timeline a lot or you will ship late. Egos in the aquired company have to be stroked just right, or you'll have a talent exodus and you'll have just bought a bunch of equipment.

I mean creating new images from many individual elements. Specifically I'm putting together a lot of spatial data, some vector based, some bitmap based. I know the software I use benefits from a good 2D card and I've worked on ones in the past that would composite 3D and 2D objects (that's not the case for this one). It takes about 2 seconds for each image of mine to be created, which means it can't support many concurrent users. An xbox cluster would help in this case, as I could round robin the requests. Since a license for an appserver (which can support about 200 users) is around $10K, buying 50 X-boxes wouldn't be out of league for a budget proposal, and 50 Xboxes could easily support 200 users (note, I wouldn't license an appserver for each one, I'd just have the main appserver call into the cluster and just write the server portion myself).
The problems with 50 Xboxes is space and heat disipation though. I'm not saying the plan is without flaws, but it is with merit. I know there are applications out there way more sophisticated than mine (I've worked on one in the past) that couls also benefit from having dedicated imaging hardware. I'm sure there are some that could use the audio too.
The point is that France couldn't have done anything to Yahoo if they weren't already on their soil. But because Yahoo had a subsidiary in France, it was bound to their laws.
