After months of people asking me what Quickstart is, and me having to take the time to explain it, I've finally gotten up off my lazy butt (and then sat down again) and put together a project page for it.

I've begun to think that my truck hates me. Last weekend, I had it at the shop because the heater has been working intermittently this winter. It turns out that the heater core was clogged, which meant that very little hot coolant was flowing into it to actually make it work. On top of that, I needed new back tires. Those two things ended up costing me just shy of $400. A few months ago, I had all 4 shock absorbers and the front tires replaced as well as a frontend alignment and something else I'm forgetting. All of that cost $800 or so.

Tonight, when I started my truck to leave work, the Service Engine Soon light came on. I was not happy. I stopped by AutoZone on the way home to have them pull the diagnostic code. The guy hooked up the reader and the first thing he said was "Ooh, this is a fun one". I cringed. The code was "random cylinder misfire". I cringed again. He said that there a few things that would cause this problem. The first was a fuel pressure problem, which makes sense since my truck tends to idle a bit rough and have some problems starting (when the engine is cold (regardless of outside temperature), I have to turn the key for 10-15 seconds or even a second time). The second possibility is the crank and/or cam sensor. I'm sure either of these possibilities will cost me lots more money. Hopefully, this will be covered under the 3-year/36,000-mile coverage plan I got with my truck when I bought it in September 2005. I guess I'll call the dealer tomorrow.

For a while now, codeman and I have been working on a major overhaul of GLI (Gentoo Linux Installer or "the installer"). After I wrote Quickstart, it became apparently that the entire reason for GLI's current design was no longer valid, since Quickstart was already more functional as an automated installer than GLI ever would be. We decided to drop the "configure first, then install" structure that the installer was originally designed with.

The results have so far been more than we could have hoped for. The entire install is now done in real-time (like virtually every other installer out there). For example, adding/deleting a partition takes effect immediately, clicking the Next button on the stage selection screen downloads and unpacks the stage before you move on, etc. Just the partitioning change has eliminated one of the largest complaints about the installer of old (it tended to eat partition tables if there was anything "weird" about the existing layout, such as partitions out of order, primaries after an extended, overlapping partitions, etc. due to the fact that it had to track all the changes in memory, serialize it to XML, read it back from XML, compare to the existing disk layout, and then make the existing match what was in the XML).

This allows us to do many things that we couldn't do before, such as allowing the user to go back and change a setting if an install step fails, opening up an xterm/gnome-terminal window for 'make menuconfig' so the user can configure their own kernel, etc. Of course, you now have to babysit the installer, but you have to do that with a manual install, too.

A few weeks ago, I decided to create a myspace account on a whim. Today, out of the blue, I get a friend request from a girl named Jessica. It turns out that it's the same Jessica that was my first "girlfriend" in kindergarten and first grade. I had lost touch with her for a while after I switched schools in second grade and her mom moved to Colorado shortly after. The last time I saw her was 9 years ago when we were 13. Today was the first time I've talked to her since then.

We talked online for a few hours and got caught up. I really enjoyed our conversation, and I look forward to actually seeing her the next time she comes out to Missouri to see her siblings that live with her father. I told my wife about this, and of course, she over-reacted initially. It's not like Jessica is out to "get me back" or something like that...she's actually looking forward to meeting my wife. For some reason, my wife always seems to think that someone is waiting just around the corner to take me away from her. If you've seen my picture, you'd know this is just crazy

She seems to have returned to "normal" for now, but I'm sure I'll hear about it later Anyway, it's worth whatever crap my wife may give me to have have an old friend back in my life, however limited (by distance and such) it may be. I have more than a few acquaintances, but I have very few good friends, and I'm hoping Jessica turns back into just that.

You may have read about when I first dislocated my knee cap (here). Well, I've managed to do it again.

There was a big "winter storm" that came through St. Louis last night. There's snow and ice all over the damn place. Well, I drive a 2003 Chevy S-10, which unfortunately, is rear-wheel drive. That means that it has absolutely horrible traction on anything the least bit slippery.

Anyway, my truck got stuck trying to pull into a parking spot at my apartment. My wife was in the driver's seat, and some helpful people and I were pushing the back of the truck. The truck finally gave and surged forward. I slipped and my knee went sideways. The knee cap popped out of place and then immediately back in.

It hurts a hell of a lot less than the first time I did it. I guess I already did most of the damage to the surrounding tissue the first time. I can still walk on it somewhat, which is definitely a good thing. At least I have two and a half days before I have to go back to work (my work was closed today due to the snow).

Over the weekend, I managed to dislocate my left knee. Needless to say, it hurt like hell. I managed to pop it back into place right after it happened, but it's swollen and I can't put much pressure on it. It's currently in an immobilizing brace pending a visit to an orthopedist.

The story of how it happened is slightly humorous (even to me). There have been some pine cones in the bed of my truck for about a week. They've been rolling around back there making all kinds of noise, which has been getting on my nerves. I decided to climb into the bed and toss them out. I put my left foot up on the tailgate (which I always do). I started to push myself up using my leg and my right arm, and then I was on the ground. I'm still not sure whether I fell and twisted with my foot still planted firmly on the tailgate, which caused my knee to dislocate, or if my knee dislocated by itself, which is what caused me to fall. I blame the pine cones.

I do have a request. If you are going to make jokes at my expense, please include me in on them, because I can always use a good laugh

UPDATE: I've got an appointment for the orthopedist tomorrow (Tuesday) at 10:30 AM. He'll probably just tell me to keep wearing the brace until the swelling goes down and happily take my money. Such is life...

In the interest of fairness, I've done a review of the Gentoo Linux Installer to complement the "review" I did of the Genux installer the other day. I tried to point out as many flaws and weaknesses as I could, since I gave the Genux installer the same "courtesy".

After the announcement today on /. about Genux doing a 2 week trial period of free support, I decided to see how far they had come. I downloaded their installer CD and wrote a little review which can be found here. Seriously, are they really going to release this thing in this condition?

I realized tonight that my 14 year old sister is wise beyond her years. Read this and let her know what you think. I wish I'd had this much insight at that age.

The other day, I obtained a cute little 333MHz iMac via eBay to use for installer work. After getting it, I find out that it uses SO-DIMM instead of SDRAM, so I can't pull memory from my other boxes to upgrade it from the 64MB it has now. I've got a laptop, but it only has 28+128 currently, so I don't want to pull any from that. Back to eBay, I guess. Isn't it cute?

 

After all my frustration with the original C3600, I found a barebones (no video, memory, or disks) C3600 on eBay for $100 (~$150 after shipping). I've frankensteined (I love that term) them together and now once again have a working C3600. Hurray!

I am ashamed of myself...

I recently managed to get a HP C3600 workstation (after a lot of frustration and having to threaten legal action...don't ask). It had been working fine for the last week or so on serial console. I decided to try to get keyboard/video working. I picked up one of those PS/2->USB adapters that handles the USB stuff for the keyboard. I plugged in the keyboard and stuck in an ATI Rage II Mach64 GT card that I had laying around. The card had been pulled (working) from my x86 box about a week ago and replaced with a card with more video memory.

The machine came up just fine but it kept going to serial console. The video card was detected:

Information Menu: Enter command > io

I/O MODULE INFORMATION
                                                                     IODC IODC

I ran a few more information commands and walked away leaving the machine running. When I came back ~15 minutes later, I saw the following on the serial console:

Main Menu: Enter command > pcoq000000f0 f000b748
    000000f0 f000b74c
ior 00001f38

pcoq000000f0 f000b748
    000000f0 f000b74c

iir 53c63e73
(same 4 lines repeating 6 more times)
pcoq000000f0 f000b748
    000

At this point, the box was locked up (not responding to any input over serial). I shut it off and turned it back on. I hear the fans and HD spinning up, but all I get on the LCD is solid blocks across the top row, and nothing comes over the serial. I've unplugged the keyboard and removed the video card, but that hasn't helped. I've left it unplugged overnight, but that didn't help. Does anyone have any idea what happened or how to fix it?

I just finished putting together a FAQ (URL changed) for the Installer project. We've been getting asked these questions over and over again, and it was starting to get a little bit annoying. Questions, comments, additions, etc. are welcome.

Recently, when testing the installer, we noticed a weird issue. When 'emerge sync' is run, rsync would complete the sync but not exit, which caused the install to hang. It took 2 days and a lot of frustration to finally track this one down. We owe the answer to d_m (on freenode).

The installer runs with 2 separate threads. The frontend is the main thread and the backend starts up a second thread to run the commands that perform the install. It turns out that when python creates a new thread, it blocks all signals for that thread. I'm not quite sure why. This has the side effect of blocking all signals for any processes that are fork()ed and/or exec()ed from that child thread.

Rsync fork()s when it's doing it's thing. One process waits for a USR2 signal from the other before they mutually exit. Since python had blocked all signals, the signal wasn't getting from one process to another so they could exit. d_m's solution was to write a small C program that resets the signal mask when running external programs. While this works, it is a huge hack. Although, this bug should be fixed in python 2.4 :-/

I earned my dev wings back in November and joined the installer team. Since then, I've written the partitioning code, the dialog frontend (now maintained by codeman), and most of the GTK frontend (Screenshots). While writing the frontends, I've come across a question that has yet to be answered: Is the installer intended to make installation easier or faster?

The original intention of the installer was for automated deployments. The way it is designed made it pretty easy to do end-user installs, also. Unfortunately, the end-user aspect of it has overshadowed the original intention. This is partially my fault with the way I'm doing the GTK frontend, but it wasn't intentional.

I've been getting pressure from users/devs to make it more user-friendly and hand-holding. Personally, I don't think we shouldn't lower the bar for Gentoo. If a user can't follow the already very detailed install guide, they won't be able to admin their Gentoo install. Making the installer hold the user's hand is only going to flood the MLs, forums, and IRC channels with dumb questions that are already answered in the install guide or related documentation. In my opinion, the user should still have to read the install guide to figure out what to do with the installer.
