Testing out a batch of 555 timers I just received. They came in a plain plastic bag so I was a bit dubious about that. So far they all seem OK to me though. The merchant even threw in an extra 4 for good luck I guess? Either that or they just couldn't be bothered counting.

Their little legs are delicate though. So the foam protects them from damage. All microelectronics are static sensitive to a degree too. Although 555 ICs are pretty rugged. Still, it'll never hurt any IC to store it in conductive foam. So it is worth it to me from an organizational point of view to just store my ICs in foam often. When I was done testing this batch I cut a piece to fit into a drawer, and put all of the chips on it, and into the drawer too.

Has anyone here built a laser pointer? I don't want to make a laser that burns anything. I just need a pointer.  I'd buy one, but I've bought a couple already, and they're pretty low quality, and tend to break quickly.

I've already looked at a bunch of resources on the 'net, and they're mainly concerned about lasers that burn things. I need a laser for some positioning tasks.

I have a round column mill and I've heard people use lasers  on them so they can raise the head, and keep the head aligned. Plus I have a cat.

Anyhow, this is the schematic I drew for a current regulator for a 5mW laser diode. I'd welcome any comments concerning what I am missing, other than an on-off switch. I know I need one of those.

Perhaps. But the diodes I have are not too picky when it comes to the amount of current they can run on. They start lasing at about 5ma, and I've driven them up to 20ma with no apparent deleterious effects. At somewhere around 13ma I'm pretty happy with the spot they put out too.

I just noticed that my tab completion is broken in my Debian Wheezy.

Double tab on a blank command line does not return:
Display all XXXX possibilities? (y or n)

Which is the behavior I am familiar with. This is an issue that is new to me so I would appreciate it if anyone has any information about this that could shed some light on it all for me. Thank you.

Mine works if there is some text too, but it cannot double tab a blank line correctly. Which as far as I am concerned is broken. All it does is error beep. Every other copy of Linux I have run in the past 20 years has output the, "Display all XXXX possibilities? (y or n)" text. Which is the way it is supposed to work.

Debian seems to break that behavior somehow. It may be intentional. I do not know. All I know is I do not like it.

If they started out using rocks as tools then I'd say a very long time indeed.

I finally setup this PC to play Quake on again. Whoohoo! I'd have gotten it going sooner but the engine I use is no longer offered in the repository for the version of Debian I am running now. Boo! So I built it from source code.

-rwxr-xr-x 1 pfred1 pfred1 3607828 Mar 14 12:11 darkplaces-glx

$ file darkplaces-glx
darkplaces-glx: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xf9b917753188b26eb72c3bc8d5d010d3d1cc86b4, stripped

Then I moved my whole old quake directory from my old system over to this one. I have that HDD mounted in this filesystem for occasions like this. I still need to associate a spiffy icon with the binary executable. #firstworldproblems

Now to setup original Doom. I am stoked to get an engine called doomsday for it going.

I had some performance issues with my old 2 GHz P4 and Darkplaces. The end of Marcher used to stutter horribly running it. I forget what the total monster count is on that map, it is in the thousands. When you come out of the belfry about half of them are waiting for you then too. But with my newer PCs they seem to handle the load a lot better. It may even have been the video adapter in that P4 that caused the trouble. It only has a Geforce MX 400 card in it.

I like visual gimmicks in Quake. I like visual gimmicks in all video games really. The more gimmicks the merrier.

Apart from a fatal design flaw that allows the propellor to smash the rotary "wing" if you pitch forward instead of banking.

Just a screenshot of my desktop. I am starting to customize all of my directory icons in my file manager. I make SVG icons in Inkscape using its trace bitmap function. I'm just putting the personal into personal computing I suppose?

I also made the Quake icon on the desktop, and the Firefox, and Thunderbird icons on the taskbar too.

I appreciate your sentiment even in the face of something underwhelming to my aesthetic. I need to borrow some motivation.

+Chris Ahlstrom I'm pretty sure I can map graphics to every element in xcalc. There is a resource called bitmap for every component. I'm not so sure if I want to get quite that involved with it all though. Maybe?

This just in. Blomkamp may need to learn a new phrase to get by in life now. Something along the lines of, Would you like fries with that?

What? No Xenomorphs in Prometheus 2! How is leaving an Alien out of a movie in the Alien franchise a good thing?
When “Prometheus” came out about three years ago, it wasn’t received very warmly – quite on the contrary, many film fans were disappointed with what the film had to offer, and expressed their frustrat

It was pretty clear to me that most of the team was just there for the money. So them acting in the best interests of their wallets, as opposed to being team players, isn't much of a stretch.

I also don't think it was viewed as the biggest science mission by many either. They had no idea what they would find, if anything by following the crazy scientists. It was just a job to them.

I really think you brought too much to the movie, and that is why it disappointed you too.

I just had a sandwich earlier on some of their bread. I consider it second to none. Makes the best French Toast too!

I ate their pizza once. Afterwards I thought I should have gotten it with the antacid topping. The sauce was raw, you have to cook that stuff before you put it on the pie! I've tried a bunch of pizza in Delaware, now I know better, so if I want good pizza I go to New Jersey.
