Real name: Christian Lercher

Started programming when I was 7 years old (Basic on C64, then Assembler, later C/C++, and now mostly Java).

First Windows experience: ca 1993 (Win 3.11)

First Unix experience: 1998 (Solaris, then SuSE Linux, now mostly Debian/Ubuntu and MacOS).

I'm just as much interested in technical things, as in social topics, and economics. It really depends.

If you haven't seen any, and you like the topic so much, that you thought about creating one - I'd say go for it! Maybe together with some people from webmasters.stackexchange.com, stackoverflow and serverfault. Could be great!

comment in Web Design What format does Web Designer, Developer and Client prefer? Is it PSD, AI, EPS. or Firework's PNG
@Tim: I must admit, that I've never tried that. Probably I'm overcautious, but I'm always worried, that it may not be 100% accurate, including color profiles etc.

I actually do know a few companies, where the dev team doesn't have Photoshop, because it isn't available on Linux...

comment How do I choose the proper font & size for my site?
+1 I agree, defining relative sizes (using em or %) is the best we can do. We can only hope, that the user finds out how to do a page zoom (or at least, a text zoom).

comment Rolling Updates in a Webserver Farm?
@danlefree: This could probably lead to a solution. But multi master replication isn't free - usually you either lose ACID properties, or you introduce 2phase-commit locking overhead (which would again mean downtime, until all servers agree, that they can actually execute the transaction). I assume, there may be advanced methods to overcome (most of) the problems - I'd be really interested in seeing such a solution!

comment Rolling Updates in a Webserver Farm?
The problem doesn't disappear when you have multiple database instances (as long as multiple servers need to access the same data). When you stop the first DB server, and continue creating TXs on the second one, and then restart the first DB, you will need to synchronize the transactions from the second DB, before you can continue using the first DB (otherwise you'd change the order of transactions!). But you can't do that before you have also upgraded the second DB. So you have a downtime. Or do you see an easy solution?

That's not so easy, when the database structure changes. When multiple servers access the same database, you can't update the schema, before all servers are also up to date. And you can't update (+start) any server, before the schema is updated...

comment Choosing which domain to secure
@Farseeker: You can set the cookie for .example.com (or example.com, which is the same), and it will work for both www.example.com and secure.example.com (with the drawback, that it will always be sent to both subdomains). Here's my favorite page on this topic: code.google.com/p/browsersec/wiki/…
