I read the Pragmatic Programmer a couple years back,  nothing terribly
illuminating however it was enjoyable and I really liked the idea of
trying to contain so muhc of the good common sense wisdom about
programming/software engineering and trying to put it in to a tome for
beginners and such.  I like lists and such.   Anyone know of a
community effort to put together something like this?  What I'd like
is something like wiki that can suck the contents of it in to a book
type format.

I got to thinking. This is sort of like my own blog.. Call me stupid but it only took like 2 years for me to realize that fact. I'll start putting stuff here more regularly. Pull my GPG/PGP keys from www.keyserver.net. I'm big on signing and encrypting all email anymore. Get enigmail with mozilla or evolution and start partying with email encryption. I even put my photo in my keys so you can see my mug shot if you start encrypting your email.

I've been preoccupied with this SCO business lately. I worked at IBM for 5 years. I simply cannot imagine that company stealing another company's work. Integrity has a premium placed on it within IBM. More importantly, SCO hasn't done anything that IBM didn't do 30 years earlier. It just doesn't make a lot of sense to me. I know they've had a speckled history, AIX for IA32 was really SCO, I always joke that they picked SCO because it has a name that is 3 letters long and that made the sed script to replace it with "IBM"that much easier. SCO has been slow to "get it" and I fear that becaose of that they feel that they have a decreasing number of chances left for them. IBM will slap them silly if they aren't careful.

Haven't entered anything in a while... I'm busy. Doing security software. Still alive and well. Still doing free software, still making a living at it.

Having fun. It's an interesting time for our movement and out industry. I'm optimistic.

more later. peace, love, God Bless,



Okay, I hope people read this. Send me a note at ian.nelson@echostar.com if you wish to discuss it.

Here is my question. What the hell good are SysV Queues? The Linux kernel limits them to 16. So you have a software resource that is limited to 16 instances. That just seems low. With such a small number of them they are a valuble resource, how do you decide who can and can't use them?

The logical next question is what the hell good is SysV IPC at all? Anyone? Anyone? If you want to really ponder this, what you need to do is architect a system, a complex one, and use SysV queues for IPC, only then will you have the true state of mind to enjoy this problem. Former Windows hacks think they are the logical choice for IPC. Fortunately you can bump a constant in the kernel and ramp the max up to 64 or something but that feels like a bandaid for a bullet wound.

I haven't put anything up in here in a while. So here is an update.

Christmas was great, saw a lot of old friends and had a wonderful time.

As for code.. I'm getting to be guruesque in the Linux boot process, I wrote a bootloader for the NatSemi Geode chipset and then hacked the kernel to load out of flash and load an initrd from flash. It's pretty cool, a pain to debug and code though.

I'm also hacking the reiserfs to have a holepunch() function in it so we can truncate the heads of files quickly. This is kind of a low priority at the time but I want to get it done.

I'm getting to be expert at Gtk+ and Gtk--, I'm quite fond of Gtk-- actually. I've been bounced around a lot at work, I do lowlevel stuff and then I get pitched in to high level app work because the bosses can't plan very well.

I've also built a full Linux distribution for Echostar called DISHLinux. Not a terribly challenging task, just time consuming. I've built a Makefile and a set of python scripts that will build it for you all in one shot.

I was doing a lot of stuff with Mozilla but we have decided to not persue it at this time. It's a shame, I think it's coming together.

All of that and then I'm getting in some hours on the bike and snowboarding.. So all in all life is pretty good.

Wow. My first entry.

Basically, I'm a full time, paid opensource developer at the moment and I'm loving it. It's really funny how your job affects your whole life. I'm a much better person in numerous ways now that I'm passionate about my job. I feel as if I'm helping to change the world. If you do Linux and want a job in Colorado, drop me a line, we need more good people.

Hopefully in about 6 weeks we'll put up a page so that our opensourced stuff will be out for general consumption. We're doing embedded stuff with Linux and I think we got a few major pieces of code that can significantly lower the entry cost for others, I'm excited about that.

My old friend Greg certified me, I haven't seen him in ages. It looks like he has moved to California, I'll have to drop him a line and see how he's doing. The world is small.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
