The World's Nine Largest Science Projects 89

JBG667 writes "Nice overview of the 9 largest science projects currently ongoing. Some of the usual suspects are on the list including CERN, Space Elevator, Space Station, etc. As well as some lesser known including a 3,000-foot-tall 'Solar tower,' the ANTARES underwater neutrino detecting array, and more. Nice read for science buffs."

Charter's Trials of NebuAd Halted 97

RalphTheWonderLlama writes "The trials of NebuAd by Charter Communications were halted after it gained the attention of Congressmen Ed Markey and Joe Barton. The online behavioral targeting system has been called "a 'man-in-the-middle attack' and various other unflattering names" but would certainly be an easy way for an ISP to cash in on client profiling." PaisteUser points out MSNBC's coverage as well, according to which the ad-insertion scheme was dropped because of "concerns raised by customers."

How Facebook Stores Billions of Photos 154

David Gobaud writes "Jason Sobel, the manager of infrastructure engineering at Facebook, gave an interesting presentation titled Needle in a Haystack: Efficient Storage of Billions of Photos at Stanford for the Stanford ACM. Jason explains how Facebook efficiently stores ~6.5 billion images, in 4 or 5 sizes each, totaling ~30 billion files, and a total of 540 TB and serving 475,000 images per second at peak. The presentation is now online here in the form of a Flowgram."

An anonymous reader writes "Bjarne Stroustrup, the creative force behind one of the most widely used and successful programming languages — C++ — is featured in an in-depth 8-page interview where he reveals everything programmers and software engineers should know about C++; its history, what it was intended to do, where it is at now, and of course what all good code-writers should think about when using the language he created."

Dodd, Feingold To Try and Filibuster Immunity Bill 368

shma writes "This morning the senate has a scheduled cloture vote to cut off debate on the FISA bill which grants retroactive immunity to telecoms who engaged in warrantless wiretapping. Senators Russ Feingold and Christopher Dodd have pledged to try and filibuster the bill, but require the vote of 40 senators to keep the filibuster alive. The article states that a similar 'threatened filibuster failed in February, when the Senate passed a measure that granted amnesty and largely legalized the President's secret warrantless wiretapping programs.' Should they lose the cloture vote, the bill is all but assured of passing. A proposed amendment stripping the immunity provision from the bill is also expected to fail."

When Is a Self-Signed SSL Certificate Acceptable? 627

UltraLoser writes "When is it acceptable to encourage users to accept a self-signed SSL cert? Recently the staff of a certain Web site turned on optional SSL with a self-signed and domain-mismatched certificate for its users and encourages them to add an exception for this certificate. Their defense is that it is just as secure as one signed by a commercial CA; and because their site exists for the distribution of copyrighted material the staff do not want to have their personal information in the hands of a CA. In their situation is it acceptable to encourage users to trust this certificate or is this giving users a false sense of security?"
