I'm a sysadmin for Sentry Data Systems. I do linux and clustering and networking, and enjoy instigating a good STONITH deathmatch when I get bored.

Work-wise, I'm a giant fan of the k.I.s.s. principle - keep I.T. simple, stupid. Don't make things any more complex than the features you need.

In my spare time, I renovate houses and ride herd on a pack of dogs with extreme mental issues. My background and career are both in systems. I look at systems, analyze them, and use them or make them better. I likeCFO DIY home stuff because the systems are simple and it's rewarding to figure em out and use them. How do I know the things I do? I have probably been there, broken that, ruined the other thing, and had to figure out how to fix all of them. we have this saying in my group of friends-who-renovate-houses: "Ask me how I know."

comment attach drive in virtual box for best performance
Your question wasn't framed clearly at all. I'd definitely edit it if you can.

comment Is there anything like BizSpark for non software startups?
Yep. You really can't beat the price. For most purposes, it's a great starting server environment in a box, and you can use the Open License program for the rest.

comment Centralized password management for multiple server applications
Agreed. We actually use Novell eDirectory's LDAP implementation, because it gives us some auditing and aggregation capabilities that we need in a much larger environment and our licenses are cheap thanks to being gubmint.

comment Is it worth it to use Linux in a new business starting from scratch?
Also, Microsoft has some programs (like the Partner Program Action Pack and the Open License program for small businesses) that help you get the CALs and other licenses you need.

Solaris is still in the crowd where 'halt' does scary things.

Oh, and Gerald, I have a shirt from thinkgeek that says, "Prefectionist."

comment Obsessive behaviors in system administrators
The big part is the "business needs" part. A coworker once told me, "I got into computers so that I didn't have to think about business needs." ... and I just stared at him with my jaw hanging open. I mean, what can you say to that?!

comment MMORPG server maintenance
Actually, most of the challenges do revolve around that central state-maintaining node, the database. That's the authoritative record. All other things that seem to manage state (the server, the client, and any caching mechanisms in between) are really just negotiators in regards to what data makes it into the database. Lag is the time it takes the database to confirm back down the chain what it has recorded.

Oskar, keep in mind that the core tech behind EVE and WoW were written in about 2002, before those techs were really mature.

Usually not. They will run some predictive metrics on hardware, but they don't usually proactively replace all the fans or other 'expendable' bits in a system unless it shows signs of failing, i.e. RPMs are dropping or SMART is showing a high write error count.

comment Creating a UNIX-based VPN: pointers, guidelines and pitfalls?
sigh I've had problems with OpenVPN on Windows7 (even using Vista compatibility and run-as-administrator privileges) and on OSX using either tunnelblick or compiling a native client out of ports. Since those are the two OSes I use most when I'm away from work... it's kind of left me out in the cold.

comment Why does IIS randomly restart my web application?
I've seen this before where an app recycles due to memory use, but I've rarely seen it scheduled. Did your host have that set for a particular reason?

comment Novell Netware Support/Recommendation?
Groupwise on OES/Linux is remarkably stable and really nice compared to the Netware world. Migration was dead simple, and we can do all kinds of fun things from the OES2 (essentially, SLES 10sp2 or OpenSuSE 10) stack underneath. I'd say you really missed out.

+1 for IDM. Essential in a public company (or one that might go public) or an audited university/higher-ed context these days.

comment Novell Netware Support/Recommendation?
Novell easily beats the support behind Windows. Most of it 'just works'. It's nice grabbing kids out of college who know Linux and just plugging them straight into OES. "Huh? Tree?" "It's just LDAP." "Oh!" -- and you've got a Novell admin. No MSCE, et. al.

comment Is it sane to run a web-app framework from SVN?
It's possible to use certain revisions with svn externals. Most webapps or frameworks won't want you working off their trunk, but will branch for a major/minor release (i.e. /branches/release-1.1 will contain all updates to 1.1 from 1.1.0 to 1.1.x, you can also choose to lock to release-1.1.2). It's safer to do that than to run off of trunk with a specific revision.

comment Setting up SVN server for multiple users over http
Also, you can use the many authentication modules (i.e. mod_auth_mysql) to handle authentication in a way that's easier to administer. Apache comes with tons of authentication modules. Make sure you're using ssl (https) as users will be sending private info.

comment Where to locate power outlets on server rack?
Ward said pretty much what I was going to say. Your UPSes should be in the bottom of the rack anyway as they'll be the heaviest components.

comment NFS v4, HA Migration, and stale handles on clients
The physical disk is shared between the units. I've gone to keeping the nfs state directory mounted via ocfs, and the other filesystems (and their exports) get mounted on the server that it fails over to. It works, but there's about a 30 second lag on clients when the nfs server migrates. I'm still trying to debug that.

comment When to move past POP3 servers, and what next?
Run the numbers. Always. Always. Always run the numbers. And don't just run your favorite numbers, run all the numbers... you're looking for total cost of ownership including admin time, not just short-term expenses.
