Journal Journal: here is my once in 7yrs check in 5

Looks like the journal page is still broken so I have to scroll to the bottom to find the link to create a new journal.

sooooo why is /. dying? Ohhhhhhhh yeah.

Journal Journal: Dam! Slashdot Journal Code Sucks 1

Why the hell do I have to scroll all the way to the bottom of my journal page to find a button to post new content? But guess what? I have to do it fast, because the oh so helpful AJAX auto loads the next page of entries if I scroll down, so that means I have to scroll down and quick click the post button or else I have to keep scrolling down. WTF were they thinking?

Have they never seen any other social media site? That sort of basic functionality needs to be front and center at the top so you can... you know.... use the site.

Journal Journal: Dang I feel old in /. terms 10

I've returned to occasional /. use due to no longer working from home, and dang my user ID is low compared to a lot of the account comments I'm seeing. Did /. experience a mass exit recently and are only newbies and fresh troll accounts posting?

Journal Journal: Diffusion Cloud Chamber Observations with Video 3

Ever build an apparatus to study subatomic particles out of stuff sitting around your house? Well my friend did and this video is the result of our replication (sort of) of the Wilson Cloud Chamber. We used the updated diffusion cloud chamber design from Andy Folannd with a bit of info from Cosmicrays.org.

The apparatus is a bit finicky and prone to getting too cold, but it worked. We observed several dozen alpha particles zipping through the room interacting with the alcohol vapor. Unfortunately, no muon decays or scattering was observed. It would be interesting to try this again with a different chamber shape / height, a different temperature differential (measuring it next time), and possibly with a magnet to observe the magnetic field affects of the paths on the charged particles.

Observation notes: It greatly aided the observation to have the live video feed piped via s-video to nearby TV, so more than one person could observe the interactions. Only close proximity ~12" makes in person observation possible due to breath condensation and freezing on the cold chamber wall.

We are looking for other experiments that can be performed at home with out significant investments / highly specialized materials that exhibit the ordinarily invisible elements of our universe that also show well on video (or can be made to so so with appropriate pre-planning). Any suggestions?

Notes on the video: shot with GL2 on Matthews tripod at F1.8, 1/60th, WB to sunlight (led light source ~5400K), 0dB gain (except opening scene which had some gain) and MF locked. No specialized color / exposure profile used, no post WB. Opening text plain with background fractal keyframed movement. "Highlight" effect applied to duplicate additive track placed above source with exclusion mask applied to select sections of the video. Video trimmed to exclude empty segments. Cinescore Soundtrack. Rendered as 3Mbps Peak VBR single pass WMV.

Journal Journal: Crash Course in Linux & OSS for a Win32 QA guy 5

I need to help someone get a crash course in QA work on an OSS stack, as opposed to their previous few years of QA work on a Win32 stack. We will be installing Ubuntu tomorrow for a quick and easy workstation. Then we need to find or write a series of tasks to learn the skills to help said person get a crash course in working in / with the LAMP OSS environment.

Again, not a SW dev, or admin, just a QA guy, so tasks, reference material, etc need not be super low level. I have the perl trifecta (learning Perl, Perl Cookbook, and Reg Ex with Perl), but everything else I have relating to Linux is +5yrs old.

Journal Journal: Long time no see: (I know). Test DB app questions 2

I'm trying to figure out how to keep working at my current contracting company beyond my contract end date (next Wed). One thing I know they are working on is a test config DB; a system to store all the possible test configurations and the status of those tests. Unfortunately for them (and me) they are an all MS all the time shop. But I wonder if I could make some substantial progress towards a system (agile method with some real quick cycles) and peak their interest.
 
The system would need to be able to create new records for "revision B" of PCB board, revision X of the chip on the board, revision Y of the firmware for the chip, revision A of expansion board type Blah, firmware rev G for expansion board Blah, PDF quick start doc for entire kit Goop, etc.
 
The system would need to then be able to say "has this been tested before?" by looking at a "tests" section which would have some list of valid test IDs to run against a specific combination of components. The test lead would like to look at a page and see "board F + FW v0.1 + chip B + exp board J + exp board FW v0.0.2" has been tested on the following....... and then see a list / chart of tests performed, and tests not performed.
 
Has anyone heard of any such software? I've found TestLink via Freshmeat, TestTracking on SourceForge, TestCaseWeb (SourceForge, but hasn't been touched in 3 years), and VarTrack again on SourceForge wihthe last modificatio nat the Epoch (system time fail?). I'm not sure these are specific enough. But that doesn't mean they could not be modified to do so.
 
I would appreciate pointers on any commercial packages, but only so I could compare them. My goal is to find an existing project I can learn and be the admin for, or get a project to use as a good jump start for my own internally developed one.

Journal Journal: Extreme Makeover: Home Edition - Sneak Peak

I ditched out of work on Wednesday around 11am so I could drive 1/2hr out to Middleton Id for the final "Reveal" of Extreme Makeover: Home Edition. It was roughly 102-105 outside, with no wind, shade, or clouds. Nearly Perfect filming conditions (except for the temperature) and nearly fatal conditions for the elderly, infants, and anyone who didn't drink plenty of water (which was available). I personally drank all 2 bottles I brought (about 1.5 liter total) and then 3x1 pint bottles they provided.

I'll provide many many pictures, & video (as soon as I find a good motion tracking software so I can smooth out the jitter in some of my footage).
 
Until I get my stuff up, you can watch KVTB's great coverage (IE required - at least it doesn't work with my FF) and read about it as well.

Journal Journal: Heights Of Idaho 2

I have published my photo album from this weekend's climb up Mount McCaleb, Idaho. Lots of photos, and several extremely large stitched panoramas (complete with trial software text printed in the middle of each picture). I might end up buying that software because it sure is slick. I had to manually stitch most of them together and the results are still pretty impressive.
 
If you notice the captions changing it is because I am in the middle of adding them right now. I might finish some time tonight. Enjoy some of the Heights Of Idaho.

Journal Journal: (Mirror) Bicycle Commuting: Day 4 & 5 - More Gear, More $ 2

My de-wimp-ifying is progressing slowly but surely. I biked in to work two days in a row! A first for me. Also impressive is that I got in to work before 10am both times which means I biked some time around 9am and it was in the 50s. Not exactly biking weather either with morning temperatures in the mid 50s with mild winds.

I have determined that I need actual riding clothing because my running outfit is just not meant for cold weather and wind. That outfit just feels like cheese cloth when faced with blustery weather and temperatures in the mid 50s (even in the sun). I smell some clothing upgrades in the future.

Speaking of clothing upgrades, I returned the helmet and the ill-fitting biking shorts for $69, but then purchased a wind proof jacket for $25 (chah-ching), summer riding shirt for $35 (chah-ching-ing), and padded bike shorts for $40 (chah-ching-ching-ing). Net expenditure of $31 which equals my planned accessory purchase for 2007-Q1. Next on the list is an odometer / calculator which could run around $30 with tax. That item is on sale through the web site so I'll probably buy it today (chah-ching-ka-ching-a-ling-a-ring-ding) Assuming I limit myself to one $30 purchase each quarter, I will break even in the Third Quarter of 2008 which is only 1.5 years from now.

Eventually I'll have all the gizmos and doo-dads possible so after 3 years of buying a new toy / item each quarter I'll assume that droops to $10 or so and replacement costs will increase from $30 / year to $60 / year.

I will be saving anywhere from $115 to $170 each quarter or $38 to $56 each month. That is as much as having the home phone line (on the low end) or a cell phone plan (on the high end). And now that I look at the numbers it does make me want to cancel the home phone which costs $35 / month and reduce my cell plan.

So what are you spending money on that could be eliminated?

Journal Journal: (Multiply Mirror) Bicycle Commuting: Day 3

So I skipped a day..... meh. I didn't get enough sleep and it was cold in the morning. No way am I riding when it is that cold. See Day 2 for details of road, weather, etc etc.

Eventually it would be nice to be a bit more consistent with this.
