Math, Programming, and Language Learning 241

An anonymous reader writes: There's often debate amongst modern programmers about how much math a professional developer should know, and to what extent programming is math. Learning to program is often viewed as being on a spectrum between learning math and learning spoken/written languages. But in a new article, Jeremy Kun argues that the spectrum should be formulated another way: Human language -> Mathematics -> Programming. "Having studied all three subjects, I'd argue that mathematics falls between language and programming on the hierarchy of rigor. ... [T]he hierarchy of abstraction is the exact reverse, with programming being the most concrete and language being the most abstract. Perhaps this is why people consider mathematics a bridge between human language and programming. Because it allows you to express more formal ideas in a more concrete language, without making you worry about such specific hardware details like whether your integers are capped at 32 bits or 64. Indeed, if you think that the core of programming is expressing abstract ideas in a concrete language, then this makes a lot of sense. This is precisely why learning mathematics is 'better' at helping you learn the kind of abstract thinking you want for programming than language. Because mathematics is closer to programming on the hierarchy. It helps even more that mathematics and programming readily share topics."

Chicago Red Light Cameras Issue Thousands of Bogus Tickets 229

mpicpp points out a report in the Chicago Tribune saying that thousands of the city's drivers have been wrongfully ticketed for red light violations because of "faulty equipment, human tinkering, or both." The Tribune's investigation uncovered the bogus tickets by analyzing the data from over 4 million tickets issued in the past seven years. Cameras that for years generated just a few tickets daily suddenly caught dozens of drivers a day. One camera near the United Center rocketed from generating one ticket per day to 56 per day for a two-week period last summer before mysteriously dropping back to normal. Tickets for so-called rolling right turns on red shot up during some of the most dramatic spikes, suggesting an unannounced change in enforcement. One North Side camera generated only a dozen tickets for rolling rights out of 100 total tickets in the entire second half of 2011. Then, over a 12-day spike, it spewed 563 tickets — 560 of them for rolling rights. Many of the spikes were marked by periods immediately before or after when no tickets were issued — downtimes suggesting human intervention that should have been documented. City officials said they cannot explain the absence of such records.

Ask Slashdot: How Many Employees Does Microsoft Really Need? 272

An anonymous reader writes: Yesterday, word came down that Microsoft was starting to lay off some 18,000 workers. As of June 5th, Microsoft reported a total employee headcount of 127,005, so they're cutting about 15% of their jobs. That's actually a pretty huge percentage, even taking into account the redundancies created by the Nokia acquisition. Obviously, there's an upper limit to how much of your workforce you can let go at one time, so I'm willing to bet Microsoft's management thinks thousands more people aren't worth keeping around. How many employees does Microsoft realistically need? The company is famous for its huge teams that don't work together well, and excessive middle management. But they also have a huge number of software projects, and some of the projects, like Windows and Office, need big teams to develop. How would we go about estimating the total workforce Microsoft needs? (Other headcounts for reference: Apple: 80,000, Amazon: 124,600, IBM: 431,212, Red Hat: 5,000+, Facebook: 6,800, Google: 52,000, Intel: 104,900.)

Verizon's Accidental Mea Culpa 390

Posted by Soulskill
from the information-wants-to-be-hamstrung dept.
Barryke writes: Verizon has blamed Netflix for the streaming slowdowns their customers have been seeing. It seems the Verizon blog post defending this accusation has backfired in a spectacular way: The chief has clearly admitted that Verizon has capacity to spare, and is deliberately constraining throughput from network providers. Level3, a major ISP that interconnects with Verizon's networks, responded by showing a diagram that visualizes the underpowered interconnect problem and explaining why Verizon's own post indicates how it restricts data flow. Level3 also offered to pay for the necessary upgrades to Verizon hardware: "... these cards are very cheap, a few thousand dollars for each 10 Gbps card which could support 5,000 streams or more. If that's the case, we'll buy one for them. Maybe they can't afford the small piece of cable between our two ports. If that's the case, we'll provide it. Heck, we'll even install it." I'm curious to see Verizon's response to this straightforward accusation of throttling paying users (which tech-savvy readers were quick to confirm).

Russia Prepares For Internet War Over Malaysian Jet 503

An anonymous reader writes The investigation of a Malaysian passenger jet shot down over Ukrainian rebel held territory is heating up. U.S. and U.K. news organizations are studiously trying to spread the blame, Russian ITAR, which, just earlier today was celebrating the downing of a large aircraft by rebel missiles in Torez (Google cache) is reporting that the rebels do not have access to the missiles needed for such attacks. The rebel commander who earlier today reported the downing of the aircraft has also issued a correction to earlier reports that they had captured BUK air defense systems with Russian sources now stating that the rebels do not posses such air defenses. The Ukrainian president has been attempting to frame the incident as a "terrorist attack". President Obama made contact with Vladimir Putin and has been instead treating it as an accident, calling it a "terrible tragedy" and saying that the priority is investigating whether U.S. citizens were involved. With control of the black box and its own internet propaganda army Russia may be in a good position to win the propaganda war.
