Timbuk2 Shotwell

The materials in my beloved (decade old) Clive Front are now so degraded there isn’t much point in sending it away for warranty service over and over – the coatings on the nylon are peeling and the thinner internal material has degraded to the extent that it shreds if you look at it funny. One of the side pouches perforated into the main compartment shortly after the last round of warranty, and I started looking into replacements. There really isn’t an equivalent bag on the market (What happened to lightly padded external pockets?), and I quickly found myself in the land of hipster brands and tacticool bags looking for a suitable replacement. I ended up getting myself a Timbuk2 Shotwell, as it was the bag that came closest to what I wanted. It was also only about $65 with creative shopping, which is enormously cheaper than most of the other contenders. (fair warning: I was lazy and uploaded camera resolution pictures, the linked images are huge)

I’ve been using it for a couple weeks now, and couldn’t find a much in the way of independent reviews when I ordered, so, some notes, in no particular order:

  • The materials quality is really quite nice. Good, well treated nylon with finer weave lining.
  • The workmanship on the bag is also good – tight seams, most of which are corded (or wrapped?) toward the inside of the bag. For the curious it was apparently manufactured in the Philippines.
  • The fabric this thing is made of is better at attracting cat hair than most of those brushes for getting pet hair off of furniture. Set it down on something that has been furred, and it will be covered for days.
  • The strap design is merely OK – the straps are square and fairly narrowly mounted, which does make it ride close and snug to the body, but isn’t quite as comfortable as yoke-style straps a lot of bags have.
  • The front pockets are kind of vestigial — too small for a CD, too shallow for much of anything. I have some candy and one of those little first aid kit boxes stuffed in them, and it bulges a bit.
  • I’m not impressed with the internally facing organizer. I would really prefer it if the center patch of the bag were a fold-out compartment with the organizer, or there was at least a surround/cover for the internal one. That said, it holds things pretty well (compact camera, post-its, some pens, etc.), and the zippered pouch behind it is easily large enough for the CD case of oft-needed media, and quite inobtrusive. I couldn’t find a picture of it when I ordered mine, so:Internal Organizer on Timbuk2 Shotwell
  • The peculiar bottom pouch is pretty clever. It is separated from the main compartment by a flexible liner, will “grab” a (or at least my) glasses case in the vertical orientation at the tall end, and can easily accommodate a power brick, some cables, and a few odds and ends. It is set up so that it will push out rather than being crushed by the contents of the main compartment. For the students, scientists, and engineering types, this is the only pouch other than the main compartment large enough for a full-sized calculator.

  • The umbrella/water bottle sleeve on the side is the best designed one I’ve encountered. The elastic is loaded enough that it goes flush when empty, and the surface is snag-proof, unlike certain other vendor’s free-hanging mesh monstrosities.
  • The internal laptop sleeve is likewise better thought out than most. Instead of padding the hell out of it, and making a bulky, mildewing mess, it is just a flat piece of nylon and elastic, that pulls the laptop up off the bottom of the bag and against the padding in the back of the bag. It is just barely large enough to accommodate my 15.6″ T510 with a 9-cell battery – the machine can be forced in with a neoprene sleeve on the laptop, but it is a better fit without.
  • This is an interaction quibble, but the 9-cell battery bulge on my T510 tends to catch the back zipper/zipper cover when pulling it out of the sleeve. I’ve also noticed some faint scrapes in the T510’s Thinkpad Finish which appear to be from the top edge of the sleeve.
  • The total capacity is rather low, to maintain the bag’s low profile. There is room for two full one-inch binders (to pick a standard-sized reference) in addition to the laptop, and that is about it. This mostly suits me, since I’m usually just carrying a laptop and a pad holder with some paper, but I can’t stick a bunch of groceries in there like I could with it’s predecessor.
  • The bottle opener on the strap is a stupid gimmick. It sticks up, it clanks, and it isn’t really useful for anything. I wonder if it will void my warranty if I just slice it off…

I’m pretty pleased with it overall.

OS X Review History

I really enjoyed this article from ars technica going through their past reviews of OS X… right up until the part where the author apparently forgets that most of the criticisms from the previous five pages are at least as valid now as they were when originally made, and declares it a good system after all. It fails to pick at some of my favorites, like the total lack of look-and-feel consistency (Apple ships first-party programs in no less than eight different widget sets – and people look down on the GTK/Qt thing on Linux), but nicely articulates many of the things that are so irritating about Apple’s UI design of late.

I’ll freely admit that the classic Mac OS was a technical disaster (Cooperative multitasking? Really?), but it was a marvel of UI consistency, owing largely to the good HIG Apple put out (and developers actually followed) in that era, and it had personality. I mostly lost interest in new Macs around the time OS X came into being, despite the fleet of Macs I grew up playing with, as it was basically slow, quirky UNIX that ran on expensive hardware, with virtually nothing in common with the Classic OS. I did (and do) still regularly interact with Macs though, and am sort of amazed Apple survived the 10.0-10.1 era when the OS completely unusable, in addition to starting from scratch on native applications. I will also admit things improved – I actually kind of liked the 10.5 boxes I played with, especially since it’s UNIX-like behavior got more standard, it introduced things I’ve come to expect, like only mildly broken virtual desktops (and because Microsoft’s platform at the time was an un-recommendable turd). I set up a 10.6 VM to play with recently and it honestly “feels” worse than 10.5 did – the UI elements are even quirkier, and there is a very uncomfortable “You will do this the apple way or you won’t do it” aura, that kind of reminds me of trying to use iOS devices. It isn’t bad, it just doesn’t do anything that I couldn’t set up more to my liking a Linux box… then again, my tastes in computing devices are demonstrably weired.

Can someone explain to me the difference between “Chrome web store” and “List of links to (possibly pay-walled) webpages?” Is it just trying to cash in on Apple’s discovery that idiots will impulse buy anything when presented with such a … Continue reading

More Spiffchorder

While I was on my hardware-fiddling spree, I came across the Spiffchorder project pile tucked into the keyboard drawer of my desk. Last time I played with it I had written off the perfboard assembled one, which had been reworked so many times it looked like a solder ball, and left a working one on a breadboard. This meant it was taking up surface- and breadboard- space, and that would not do. So, I sat down, laid out a less-insane board, and soldered it up in one pass.

The design isn’t well suited to the individual-pad perfboard I had around (lots of n>2 component nodes), so I tried a fabrication strategy I hadn’t used before to help simplify: I almost completely populated the perfboard, ran a piece of tape over the components, flipped it, and soldered, rather than re-adding the components as I went. It actually worked pretty nicely. It is a little bigger than the last layout I used, but this one worked on the first try – or at least the first try where I had a programmed UC plugged in to the socket…

In a related matter, one of the two chips I thought I had burnt with the appropriate firmware doesn’t seem to be working, and because there is a bug with the -g flag in the current version of gcc-avr, I can’t burn another from the boxes I have set up for working with AVRs (the VUSB stack needs the -g flag).

The actual chorder I made still sucks almost to the point of being unusable, largely owing to a mistake on the particular tactile buttons I got when I ordered the parts. Eventually something will have to be done about that, but the chorder is on a header, and the project is now in an electronically working state, not taking up prototyping supplies, and can be shoved in a box when idle.

I thought I was going for a nice long skate in the beautiful weather. My heart, lungs, and left (lift) knee had other plans, and cut me off at a little under 30 minutes. I didn’t realize I was that … Continue reading

CNC Update

I’ve been in a very mechanical sort of mood for the last couple days, no doubt owing to the all-software (and intangible even for that – what does that thing you’ve been working on do? – well, if I were sure it was working it would verify that an input sequence is valid in this language I made up…) sorts of things I’ve been doing of late. So, I pulled out my pile of mechatronics parts and started fiddling with it.

I’ve previously documented some of this elsewhere, and this isn’t a finished project, but I need a brain dump to package up various information, so I’m going to do a fairly thorough write up.

Hundreds of dollars of parts, hours of fiddling and “Hey! It almost drew a circle!” (I’ve been playing with my CNC parts pile again – more later)

Wikileaks on Facebook

It’s popping up all over the place, but to repost, Julian Assange, Wikileaks’ human lightningrod/figurehead, on Facebook:

” Facebook in particular is the most appalling spying machine that has ever been invented. Here we have the world’s most comprehensive database about people, their relationships, their names, their addresses, their locations and the communications with each other, their relatives, all sitting within the United States, all accessible to US intelligence. Facebook, Google, Yahoo – all these major US organizations have built-in interfaces for US intelligence. It’s not a matter of serving a subpoena. They have an interface that they have developed for US intelligence to use.
Now, is it the case that Facebook is actually run by US intelligence? No, it’s not like that. It’s simply that US intelligence is able to bring to bear legal and political pressure on them. And it’s costly for them to hand out records one by one, so they have automated the process. Everyone should understand that when they add their friends to Facebook, they are doing free work for United States intelligence agencies in building this database for them.”

Admittedly, [Citation Needed], but Assange has an amazingly good track record about having information to back up his claims, and this sounds entirely plausible. The terrible thing is, I’m less concerned about unscrupulous world governments having access to that sort of thing than I am about various unaccountable corporate entities having the same (and really, generally, less concerned about unscrupulous world governments than I am about various unaccountable corporate entities). I’m sure most people don’t care, but this kind of shit is why I don’t have a facebook account, and am careful to only deal with social websites in contexts where I want everything they know about me shared with everyone (With the semi-reluctant exception of Google, who knows everything about everyone anyway, opt-in or not, and provides excellent services for opting in).

Osama Bin Laden is dead

…and man, the internet is making a party of it. Media shitshow party points:
* Bunch of the news sites (and forums, etc.) crashing.
* Hilarious notes that this is eight years to the day after Bush’s “Mission Accomplished” speech.
* He was killed by assassins in Packistan, completely ancillary to our $400Bn war in Afghanistan.

Sadly, this isn’t going to amount to much. The Patriot Act will still be in place. The TSA will be fucking shit up. The various wars in the middle east will continue. Ideologically similar/sympathetic assholes may even get riled up for a while. At least something was accomplished, small though it may be. Maybe we can pull one of these and wrap it up quickly afterwards?
