  • Python Success Stories

    ...While I did have a good bit of programming experience with C/C++, I knew very little Python when I started on this project. Yet, I was able to learn Python using only its tutorial and the standard Python documentation, and then could quickly develop a substantial application. I was pleased that Python could be learned so easily and then so readily applied to non-trivial tasks. It is important to note that this project was only a spare time activity for me, which means that I had very little su...

    ...While some work had already been started and a previous generation of the site existed, there was still an incredibly tight deadline to meet. As the site was to be one of a handful of sites mandated by the White House, it had to be done right the first time. devIS decided from the start of the project that our code had to meet two general requirements. First, the software should eventually, some time after meeting the initial deadline, be released as open source. Second, it had to be portable en...

    ...while most of the details are taken care of by Python's powerful standard libraries and the third party modules described above. Many more lines of code would have been needed working in, for example, Java or PHP. The integration capabilities of those languages are not as strong, and their threading support is harder to use. Python is impressive as an object-oriented rapid application development language. One of Python's key strengths lies in its ability to produce results quickly without sac...

Once we had the camera, we took hundreds of pictures, and showed Nat how to look through them on the computer using an off-the-shelf image viewer called ThumbsPlus. Watching Nat flip through pictures, though, I noticed something: once he became familiar with the sequence of the pictures, he was clicking on the pictures as if it mattered where he clicked. The image viewer didn't care: any click on the picture wo...

Results Happy programmers are good programmers, and good programmers work efficiently. That's what project management learned at this point in our effort....

Smack in the middle of the Nutshell's gestation, an emergency emerged (as emergencies will :-)—the Python Cookbook just wasn't going to happen unless somebody with lots of Python nous AND some writing and editing skills could devote a very substantial slice of time to selecting and editing recipes. I suspended the Nutshell work, took all my accumulated vacation from work, and then some....

Its computer graphics division dates back to 1979, and its first CG production was the 1982 Genesis sequence from Star Trek II: The Wrath of Khan. In the early days, ILM was involved with the creation of custom computer graphics hardware and software for scanning, modeling, rendering, and compositing (the process of joining rend...
