There’s a “standard model” that works for writing reliable, performant and secure RIAs — it works for GWT, Flex, and Silverlight and plain old AJAX apps too.

It’s not always easy to find good documentation online for the Microsoft universe, but Joe Albahari has written a great article about Threading in C#.

Daniel Eran Dilger has been a leading writer about the iPhone since before it came out, and this week he writes about the choices Apple made about concurrency in the iPhone. Unlike Windows Mobile, the iPhone only allows the user to have a single third-party application running at a time. Dan makes the case that portables don’t provide a rich enough interface to let users juggle multiple running tasks (it’s hard enough to do this with a desktop computer) and that it won’t be possible to give a phone-like experience without tight control on process lifecycle.
He’s right. I’ve got a friend who has an HTC handheld that runs Windows Mobile. It looks nice, and it’s got some good features, but every so often it gets in a state that pegs the CPU at 100%; it gets warm pretty quick, so this can’t be good for battery life. Vendors like Apple, Sun and Nintendo, who have a lot of control over hardware and software aspects of platform, can often users an experience that can’t be matched by more open platforms, where no vendor claims responsibility for the performance of a system.

Tom’s Hardware has a nice review of the Core Installation of Windows Server 2008, which makes it possible to install Windows Server 2008 with a limited GUI. It’s exciting to see Windows get more mature and flexible: the core install takes up about half the disk space of a conventional install. However, the fit and finish of the Core Installer is poor — for instance, an administrator needs to type more than 900 characters on the command line to install Microsoft IIS. We’ll give Microsoft another chance, but, for now, the Core Installation is less mature than text-mode linux distributions were a decade ago.
Fit and finish are important factors in choosing a server operating system — I’ve been trying to repurpose an old laptop as a media server, and finding it a challenge to find a modern Linux installation that installs without trouble on a machine with no DVD drive and limited RAM.

Dave Bonta photographs a red hawk on the Penn State campus, and meditates on how people’s experience of nature is conditioned by our shared hyperreality. Dave notes that ‘a helpful webpage on film sound clichés, “the Red-Tailed Hawk scree signifies outdoors and a big, lonely place.” Anytime a rocky mountainside appears in a movie, you can almost count on hearing that raspy scream, which most people probably assume belongs to an eagle. It’s also used as an all-purpose signifier of impending or just-concluded drama in the typical outdoors adventure flick.’
Most students walked by obliviously while a handful used cellphone cameras to capture the hawk attacking it’s prey. He was left with an awkward feeling that he’d met a creature from another world — but wasn’t completely sure if he, or the hawk, were the alien visitor.

Michael Arrington at Tech Crunch announces that Google Analytics now lets webmasters share data with other Google products, and suggests that they should let us share web statistics with everyone, a suggestion that I find a little disturbing.
Like it or not, web marketing is cutthroat, and search engine optimizers are always looking for an edge on the competition — open web statistics are an invitation for somebody else to eat your lunch.
Personally, I like Quantcast, which provides public statistics about the readership of web sites that are useful for advertisers and others, but that respect the privacy of webmasters and users.

There’s a nice article at the Torque Report about the Toyota iQ, which hits the road next fall. In a bit of national pride, Toyota based the design on the ‘J-Factor’, “that aspect of Japanese originality and quality that creates modern, attractive, and globally appealing products from the apparent disharmony and contradictory nature of its original components.” Toyota developed six major technical innovations to develop a car less than 3 meters with great drivability and comfortable seating for three adults and a child.
I’ve long noticed the difference in priorities between US and Japanese car manufacturers. The Corolla and Civic were designed by people who are passionate about small cars — they’re small on the outside but big on the inside. The Chevy Cobalt, on the other hand, seems to be designed by people who think that driving a small car is like wearing a hair shirt, and even likable vehicles like the Dodge Caliber and Buick Lacrosse seem quite puffy: oddly small on the outside for the large exterior.
With gas at $3.40 a gallon and heading up, we can only hope that American carmakers will focus innovation on fuel efficiency and appealing small cars rather than gimmicks such as OnStar and ultrasonic sensors to keep you from mashing the back wall of your garage with an oversized vehicle.

It looked like a winter wonderland when I woke up in Brooktondale this morning, about 1000 feet above the lake. I found that the ice had melted in Ithaca, where I drove to do some business. I drove up route 13 around 10 am, on the stretch between Stewart Park and the Mall, which cuts a diagonal up the Cayuga Lake Valley with sweeping vistas of Ithaca and the Lake. I looked across the lake to the other side of the lake, and noticed that above a certain altitude the trees were silvery — they were still covered with ice. I rounded the bend at the end of the straight segment of the road and suddenly the trees around me were covered with ice as well.
One thing I like about the Ithaca area is the variation of microclimates: it can be raining downtown but snowing at Cornell. Downtown gardeners appreciate being able to grow plants that would otherwise need to be a few hundred miles south to grow; the microclimates on the slopes of the finger lakes are essential for our growing wine industry.
