Top 10 Things That Annoy Programmers | Kevin William Pang 10. Comments explaining “what”, but not “why” Introductory-level programming courses teach students to comment early and often. Do you have any idea what the code above does? Me neither. The problem is that while there are plenty of comments describing what the code is doing, there are none describing why it’s doing it. Much better! Write comments to help readers understand the code, not the syntax. 9. In general, programmers tend to be more akin to locomotives than ferraris; it may take us awhile to get started, but once we hit our stride we can get an impressive amount of work done. 8. Wikipedia defines scope creep as “uncontrolled changes in a project’s scope”.

What do High School students want from mobile tech? [Infographic] Based on statistics provided by PEW research, Nielsen, the National School Board Association and others, ASCD's infographic explores the connections between today's students, mobile learning and learning methods. The majority of Western schools attempt to ban the use of mobile devices; whereas a smaller number permit students to carry but not use the items. For many, suppressing such items becomes a losing battle -- as students continue to bring them, as well as parents preferring the option of being able to contact their children. According to the research, 63 percent of students attending schools carry their mobile devices despite the rules. Schools, in general, consider mobile devices a distraction and a way that more children experience bullying. Young people are becoming 'wired' and proficient with Internet use at an earlier age.

Ok, I'm convinced Toyota's assembly line of the 1980s was famously efficient due to its revolutionary approach towards defect prevention. Developers often make the faulty assumption that productivity = cranking out code quickly. 3. In other words, what happens if you suddenly lost a key member of your team? 4. 5. Sound familiar? 6. 7.
