Chromium

I downloaded Chromium (google chrome, but purely FOSS, so there is a build that can be grabbed directly from the Arch repos) to play with this weekend, and it is way more promising than last time I played with it. In particular, I wanted to see if the touted speed benefits were real, and see if there was a viable alternative after the massive UI (”Open in new tab” is a critical feature for tabbed browsers…), resource consumption, and stability regressions in Epiphany after it’s switch from Gecko to WebKit.

I should note that my browser usage is a little weird; I keep one Firefox window per topic (usually 3-4) on my first virtual desktop, plus an instance of Epiphany on the second virtual desktop, which is used for mail (it stays logged in to my google account, Firefox doesn’t), banking and various other things I’d rather not have logged in alongside my normal browsing, or brought down when I manage to crash Firefox.

As for Chromium itself (I’m using “Chrome” and “Chromium” interchangeably here):

The good:
* Fast. Very, very fast. Especially javascript, which is it’s claim to fame.
* Responsive. The UI is WAY more responsive than Firefox, I’m yet to have a “did that work?” moment with it.
* The default new tab behavior that places text entered to a new tab into a google search is correct as far as I’m concerned, I’ve had Firefox set up that way for ages.
* Per-tab processes to prevent broken pages from taking down the browser.
* Extensions in separate processes. This is probably the best feature, Flash crashes all the time on my machines, and I hate having to restart Firefox to get it back.
* Incognito windows. This is a partial solution to the logged in/not logged in issue that makes me keep two browsers up.
* Perfect default tab opening behavior; tabs created from “Open link in new tab” open next to the parent tab, tabs created by ^+T open at the end of the bar. I’ve never managed to make that work consistently right in Firefox, despite having a nice extension to do so.

The bad:
* That “innovative” UI that doesn’t integrate with the desktop theme, and gets clumsy when you turn on the “Use System Title Bar and Borders” option in the vain hope that it will help.
* That same “innovative” UI that puts the tabs in that awkward fitts-law worst case scenario place close enough to the edge of the screen to require long travel, but not close enough to get edge benefits. I am not alone in this opinion, would it really be so bad to add an option to fix that?
* No scrolling tab bar. I usually have several windows with <20 tabs each, but if I spawn tabs for all the interesting unread threads in a forum or somesuch, I really like to be able to read the titles.
* Ravenous memory and cycle consumption: if you think Firefox is bad about consuming resources, just wait until you see Chrome. Then again, the latest builds of Epiphany have a nasty habit of bugging out taking up some CPU time constantly, and Chrome is way better than that.
* Awkward bookmark-group behavior. There is a “open all in new window” feature (which is very cool), but it extends to sub-folders (which is not).

Overall, it is definitely my new second-choice browser, and I’ll keep it installed to use when I have problems with Firefox. I might even switch despite the UI issues; some of the above features are really nice, and adblock works just as well with chrome (this is very important for my primary browser). It should be neat seeing the next few versions of Chrome and Firefox, real competition (sorry IE and Opera, you don’t really count) is a wonderful thing.

EDIT: Apparently adblock doesn’t work quite as well in Chrome, Firefox adblock actually prevents ad material from downloading, Chrome adblock simply prevents it from rendering. Not an issue with a fast connection and fast machine, but you might want to go ahead and fix your hosts file to get rid of the more egregious offenders anyway.

Blackboard for the Lose

I never used Blackboard as an undergrad, and from my experiences this semester using it as a student in my PSY562 class, and a TA for EE281, I am very, very glad. Every time I log into Blackboard, I get the feeling it was designed by people who have heard of the Internet, but never actually used it.

The UI is totally incohesive, painfully slow(I tried several different browsers, including Chromium, faster javascript engines don’t help much), and woefully difficult to interpret, on top of being simply ugly.

My biggest complaint however is the grade input interface (which is hard to show without running afoul of FERPA); I want a TABLE. It could be a fancy javascript spreadsheet like google docs. It could be a HTML table full of HTML textboxes with a submit button (as long as the tabbing order is column-major). It could demand some format of file upload, so long as it was capable of incremental updates. Instead, there is a nigh-unusable single-shot file upload widget, with no incrementing support, and a clumsy javascript table-thing which posts per-cell, making it miserably slow to enter to. For now, I’m just keeping grades in a spreadsheet on my machine, and taking some time each week to synch it up with blackboard, because directly using the interface is too infuriating.

I’m also noting that I’m not the only one who has issues with making Blackboard work. There is delicious irony in that more often than not there are emails or before-class discussions about failures in interacting with blackboard (usually including the instructor) in my class on Human Technology interaction.

These criticisms are aside from the issues I have with Blackboard, LLC Being dicks with (since invalidated) patents they shouldn’t have been granted in the first place

Sadly, playing with the public demo of Moodle, which seems to be the most successful open-source Course Management System, I find it really isn’t much better on most fronts, but does seem substantially more responsive, and has a slightly more cohesive UI. More importantly, it isn’t any worse, is not large tens to hundreds of thousands of dollars (ref, may have to push “Guest Login” to view) per year in licensing fees, and, as an open project, is more likely to improve with time.

Seriously, why is anyone using this thing? Is it convenient for the admins? (I doubt it with how often it seems to be down) Was it just a buzzword for a while, so everywhere that wanted to look like they were keeping up with educational technology bought a license, then couldn’t get rid of it? Does blackboard LLC have really good kickbacks for the IT people who make purchasing decisions? It doesn’t even have the obvious link with finance trolls like the other terrible, expensive software UK has adopted to explain it.
