An anonymous reader writes: Thomas Haigh, writing for Communications of the ACM, has an in-depth column about Donald Knuth and the history of computer science. It's centered on a video of Knuth giving a lecture at Stanford earlier this year, in which he sadly recounts how we're doing a poor job of capturing the development of computer science, which obscures vital experience in discovering new concepts and overcoming new obstacles. Haigh disagrees with Knuth, and explains why: "Distinguished computer scientists are prone to blur their own discipline, and in particular few dozen elite programs, with the much broader field of computing. The tools and ideas produced by computer scientists underpin all areas of IT and make possible the work carried out by network technicians, business analysts, help desk workers, and Excel programmers. That does not make those workers computer scientists. ... Computing is much bigger than computer science, and so the history of computing is much bigger than the history of computer science. Yet Knuth treated Campbell-Kelly's book on the business history of the software industry (accurately subtitled 'a history of the software industry') and all the rest of the history of computing as part of 'the history of computer science.'"Read Replies (0)

An anonymous reader writes: On Christmas Eve, the NSA quietly dropped 12 years worth of internal reports on surveillance that may have broken laws, including reports that were illegally withheld and the subject of a FOIA lawsuit in 2009. "The heavily-redacted reports include examples of data on Americans being e-mailed to unauthorized recipients, stored in unsecured computers and retained after it was supposed to be destroyed, according to the documents. ... In a 2012 case, for example, an NSA analyst 'searched her spouse’s personal telephone directory without his knowledge to obtain names and telephone numbers for targeting,' according to one report (PDF). The analyst 'has been advised to cease her activities,' it said. Other unauthorized cases were a matter of human error, not intentional misconduct. Last year, an analyst 'mistakenly requested' surveillance 'of his own personal identifier instead of the selector associated with a foreign intelligence target,' according to another report." Here's there list of reports going back to 2001.Read Replies (0)

An anonymous reader sends word that Rackspace has recovered from a severe distributed denial of service attack
. "Over on the company's Google+ page Rackspace warned of 'intermittent periods of latency, packet loss, or connectivity failures when attempting to reach rackspace.com or subdomains within rackspace.com.' The company's status report later confirmed it had '... identified a UDP DDoS attack targeting the DNS servers in our IAD, ORD, and LON data centers [North Virigina, Chicago and London]. As a result of this issue, authoritative DNS resolution for any new request to the DNS servers began to fail in the affected data centers. In order to stabilize the issue, our teams placed the impacted DNS infrastructure behind mitigation services. This service is designed to protect our infrastructure, however, due to the nature of the event, a portion of legitimate traffic to our DNS infrastructure may be inadvertently blocked. Our teams are actively working to mitigate the attack and provide service stability.'"Read Replies (0)

writes Both Xbox Live and PlayStation Network [were] down this morning, apparently due to a denial-of-service attack. The notorious hacking group Lizard Squad — which already carried out earlier attacks on Microsoft and Sony — has claimed responsibility on Twitter for these latest outages. While the group's role in all of this remains unconfirmed, it's worth noting that the group threatened last week to take down Xbox Live and PSN, according to Business Insider. And again, Lizard Squad has already proven it can successfully pull off such attacks, not to mention other malicious pranks.
Whatever the cause, the timing is obviously terrible: Plenty of people surely received one of the two consoles as Christmas presents today, while many more gamers would have happily spent the afternoon in front of the TV. In the meantime, both Sony and Microsoft have acknowledged the problem, with Sony issuing a tweet and Microsoft posting a message on its support website: "We're working to address this as quickly as we possibly can," reads its status website. "Thanks for your patience, Xbox members." In an email, a Microsoft spokesperson declined to comment further or say when the company expects to restore service. We've also asked Sony to comment and will update this post if and when it does.
The Xbox Live status page
says service remains "limited," and the Playstation Network is listed as offline

An anonymous reader writes Many companies emerged in 2014 offering new ways to help people connect, get stuff done, or find that special someone. Slack, for example, offers a chatty alternative to work email. Or Yonomi might actually make an Internet connected home feasible. But other new startups, looking for that new and original thing, peddled products that were gimmicky, legally unsound, or just not super useful.
On the other hand, sometimes things that seem gimmicky get revised down the road; Kozmo.com
is my favorite example — the business model might not have been perfect, but the underlying idea wasn't so bad. Sometimes there's a large not-being-the-first-mover advantage.Read Replies (0)
