If you said 4, you've done it the MySQL way. As quickly as possible with no regard to giving the correct answer.
Anybody can give the wrong answer quickly. I used to be a MySQL fanboy, then I started hitting the various "Gotchas" that it has where answers didn't come out correctly.
The amount of time cleaning up wasn't worth it. If 95% of their warnings were errors, I probably wouldn't have changed to PostgreSQL.
Things like the below make me nervous: InnoDB: Commit after every 10,000 copied rows when executing ALTER TABLE, CREATE INDEX, DROP INDEX or OPTIMIZE TABLE. This makes it much faster to recover from an aborted operation.
The only person who actually cares are the people making the web-sites
That's true, but consider that there is a small but growing number of websites which look just that tiny bit better in FireFox or other modern browsers than in IE.
Firefox and Safari are big enough you cannot easily ignore them anymore (for IE specific web developers); but it's pretty easy to use CSS2 to make things look a touch better, then run IE in a different mode.
My most recent website (I don't make very many) was tested primarily with Epiphany and Konqueror, then tested on Opera, Safari, Firefox and IE6.
The others came out very close to what was intended, then I stuck in a css sheet pulled in by IE only which disables or works around a bunch of stuff that it didn't display properly:
Google is small, they always get hacked and their search engine doesn't scale.
Google doesn't really use any of the scalability features in Linux. In fact, they seem to go out of their way to avoid them and instead rely almost entirely on in-house technology for scaling.
It's a bit like saying that florescent lights are scalable because you can put thousands of individual lights within a building, or that IBM laptops are scalable because you can purchase them in units of 1000 running MS Windows.
BTW, Canadian Tire is just awful - ask any Canadian.
Worse than awful, they're as bad as Walmart.
For example, they forced 3M to reduce the glue and paper in their masking tape so they could sell it cheaper than anyone else (cheaper to make). As a result the frigging stuff doesn't even work.
That's just one example, but they try to do those things with any product they can. Same label and product code, but different product.
Not only that, but a firewall adds complexity to the situation. Many Windows firewalls (including a few early Microsoft attempts) have been known to decrease security because of flaws in the firewall itself.
If you turn off everything that shouldn't be publically accessable, you should also disable the firewall of the local machine.
Seperate firewall physically separated from your important data is a different story. Buffer overflows in those probably won't give them access.
It seems that most voicemodems don't work with Asterisk.
Yeah, found that out later on that "and most other phone equipment" didn't include modems. Since I got surprised there, I'm going to triple check the same line can do voice and fax service without too much pain.
Indeed. I've been eyeing fax to email gateways for a little bit now, but don't think it's worth $20 per month recurring (potentially lots of inbound faxes). However, if this thing can run on an old junker (cheap) computer, it might be worth it.
Hey, look at that, an old junker computer in the closet that I've been meaning to donate, complete with a modem. How convenient!
[i]The question is, to what degree are CFC's responsible for the measured ozone depletion we've seen over the past 20 years or so.[/i]
Agreed. We need to be conservative about the introduction of potential solutions as well as the introduction of potential problems so we can take the opportunity to measure their true impact.
Changing 10 things at once to solve a problem makes it impossible to determine which was the right one (if not a combination). Likewise several substances with the potential to cause X should be carefully monitored for their impacts.
I likes to deal with the environment the same way I deal with my finances -- make sure it's not a crap shoot unless it's a small enough amount that it's easily recovered / corrected.
A: No, that's not it! Learning is good in and of itself!
Q: Why?
A: Personal enjoyment
Same reason some people watch TV or post endlessly on forums. Grab a lecture schedule on a topic you like and sit in on a few. School is great without the grades and assignments part.
[i]Does your son by any chance model jet engine compressors on that thing? It's a total apples to oranges comparison! It's like saying that a 777 is more expensive more expensive than your Toyota.[/i]
Not only that, but the Toyota is easier to parallel park and handles tight corners better.
It might sound odd, but it's true. Consider Virus Scanner sales for protecting email inboxes, and what is normally required to spread those viruses if one is received.
Folks who can't handle high-pressure sales do quite a bit to avoid the sales pitch (they don't goto the resort on vacation, they avoid commission stores, they buy "Caller Display" and avoid surveys, etc.), but if you can get the pitch to them, they can make for pretty easy targets -- or they're quick to get rid of the sales man.
But we do. I used to do telephone surveys for a vacuum cleaner company (school requires funds you know!). We had a special box on the form to check when the person specifically asked if we were selling something. The reason for the checkbox wasn't so the sales guys would ignore them, but because they tended to be easier to sell to.
In other words, I believe some people block popups and ads because they realize they're gullible and might buy stuff.
Why? Todays pricing indicates 512MB Memory at a touch over $100 CDN. That doesn't seem all that unreasonable compared to the videocard that you should buy for maximum quality.
"To run Doom 3 at the highest setting, the way it was meant to be run, you need a 512 MB video card, which don't even exist yet"
I've been there. Around 160GB upgraded from 7.2.4 through to 7.4, then a hardware upgrade from 7.4 to 7.4 with about 20 minutes downtime in total (for both migrations).
Check out eRServer and Slony replication methods. They have pretty heavy requirements (double to triple diskspace as normal, lots of spare CPU cycles) but can get the job done.

<!--[if lt ie 7]>
<link rel="stylesheet" href="/ie6.css" type="text/css"
<![endif] -->
IE6 displays it adequately; but the extra touches (display: table-cell instead of inline, etc.) make it come out that much cleaner.
Ahh.. That must be it.
/dev/zero blocks.
grep -a foo
grep foo /dev/zero &
/dev/zero works?
This may be a Linux only issue. FreeBSDs grep exits almost immediately, but Suse certainly spins.
I find this interesting because BSD's grep claims to be GNU Grep version 2.5.1 which is the same version as on my Suse installation.
Perhaps it's a difference in the way
Twice this week I've looked at the clock at 11:11pm, then the next time I looked it was 1:11am.
There should be prizes for things like that.

All I now need is the Postgres-R (replication) stuff to work out of the box (like it does for mysql).
Look into Slony. It's an addon project, but replication for PostgreSQL will always be an addon so that it works across multiple backend versions.
It's fairly straight forward to setup a master/slave scenario, and PgAdmin is currently working on GUI tools for managing it.
It's better than the reruns that are usually showing.

Sure, one per customer but of which corporation (Yahoo or Baskin Robbins)? Spent my coupon, so I cannot read it now.
Besides, they're close enough you can walk from one to the other for your second scoop.
Get another Yahoo account and give them both coupons. There, 2 scoops. Not stack one on the other, and give them back one of the cones.

You've obviously never purchased anything from IBM if you think Linux is a free product.

What about us people who never leave the house?
Simply place a fan next to the turbine.

Heh.. I think you've thrown off todays numbers a little bit.
That you need 384MBs RAM...

You can opt out of text message services. This is a really poor excuse.
I tried two companies. They both wanted to charge me a fee for disabling the text messaging service. Not all telco's in all countries are equivalent.
