Submission + - Digitally filtering out the drone of the World Cup 1

qubezz writes: World Cup soccer fans may think a hornet's nest has infiltrated their TVs. However the buzz that is the background soundtrack of the South African-hosted games comes from tens of thousands of plastic horns called Vuvuzelas, that are South Africa's version of ringing cowbells or throwing rats. It looks like the horns won't be banned anytime soon though.

A savvy German hacker, 'Tube' discovered that the horn sound can be effectively filtered out by applying a couple of digital notch filters to the audio at the frequencies the horn produces (another summary in English). Now it looks like even broadcasters like the the BBC and others are considering using such filters on their broadcasts.

That's actually the reason that the US government will most likely never go to a physical denomination higher than the $100 bill.

If I understand correctly, all large electronic transactions (>$10k) are auto-monitored by the banks, and tracked by the government. It is a lot harder to pay someone $50 million dollars if you do it in cash due to the size of the physical dollar bills than if you do it as an electronic payment. Given that the government wants to monitor criminal activity, super large drug cartel type money movement is a lot harder with smallish $100 bills.

$3000 being prohibitive? Try to stuff $30mil into your wallet!

Twitter Offline Due To DDoS 398

The elusive Precision dropped a submission in my lap about a DDoS taking down Twitter running on CNet. It's been down for several hours, no doubt wreaking havoc on the latest hawtness in social networking. Won't someone please think of the tweeters? Word is that both Facebook & LiveJournal have been having problems this AM as well.

So how did myself and tons of others upgrade to 3GS models in an apple store?

I left with my 3GS fully activated and able to make calls (with no data synced) and my 2G iphone with no service. No SIM card was changed.

Your phone number can be activated to a different SIM card... in the Apple Store.

Soooo....

Apple has no mechanism to transfer the registration of the SIM card to your phone number and set it up on the new phone.

is just outright wrong.

That makes sense. Common sense is that they bought a site license from an anti-virus vendor.

So how much is that Norton/Symatec/?? license for those 30,000 computers? Is that part of the Windows TCO, the mandatory virus protection and lcoal system firewall?

An answer from most people running windows is that linux systems should also have anti-virus measures in place, but in my limited experience (only ~100 machines), that was never needed since rarely was root access given out to users.

if you have driver problems with the desktop LiveCD... you should use the alternate install CD, it's what it is used for.

From https://help.ubuntu.com/community/Installation

"If your computer is not able to run the standard Desktop installation CD, you can use an Alternate installation CD instead. The Alternate CD also allows more advanced installation options which are not available with the Desktop CD. "

How do you break this down? Are they just pinging twitter.com and waiting for timeouts on html returned?

I ask, because lots of twitter is their distribution via their APIs. How many of those other moblog sites have http GETs to non-html documents? Check for yourself: http://apiwiki.twitter.com/

I wonder how many statuses were updated from facebook.com or pulled there from a twitter API poll. It would be nice if a site like facebook could post their timeouts on their user status polls they do from their site. That might give people more of an idea of the complete twitter uptime.

O'Reilly Now Competing With Sun Java Certificates 44

Joel Aufgang writes "O'Reilly Media's O'Reilly School of Technology in partnership with the University of Illinois has just launched a Java Programming Certificate Series, which looks like it's intended to compete with the Sun Certified Java Programmer (SCJP) certification. According to O'Reilly's press release, this is not an exam-based certification but rather a series of project based instructor-led courses that, if you pass, earns certification backed by the University of Illinois. Also interesting is the use of Eclipse as the preferred learning platform as opposed to Netbeans."

World Bank Under Cybersiege In "Unprecedented Crisis" 377

JagsLive sends in a Fox News report on large-scale and possibly ongoing security breaches at the World Bank. "The World Bank Group's computer network — one of the largest repositories of sensitive data about the economies of every nation — has been raided repeatedly by outsiders for more than a year, FOX News has learned. It is still not known how much information was stolen. But sources inside the bank confirm that servers in the institution's highly-restricted treasury unit were deeply penetrated with spy software last April. Invaders also had full access to the rest of the bank's network for nearly a month in June and July. In total, at least six major intrusions — two of them using the same group of IP addresses originating from China — have been detected at the World Bank since the summer of 2007, with the most recent breach occurring just last month. In a frantic midnight e-mail to colleagues, the bank's senior technology manager referred to the situation as an 'unprecedented crisis.' In fact, it may be the worst security breach ever at a global financial institution. And it has left bank officials scrambling to try to understand the nature of the year-long cyber-assault, while also trying to keep the news from leaking to the public." Update: 10/11 01:15 GMT by T : Massive spyware infestations might be good cause to reevaluate the TCO of non-Windows systems on the desktop.

Wikimedia Simplifies By Moving To Ubuntu 215

David Gerard writes "Wikimedia, the organization that runs Wikipedia and associated sites, has moved its server infrastructure entirely to Ubuntu 8.04 from a hodge-podge of Ubuntu, Red Hat, and various Fedora versions. 400 servers were involved and the project has been going on for 2 years. (There's also a small amount of OpenSolaris on the backend. All open source!)"

Viewing Tool Provides Scrutiny of Debate Footage 144

The New York Times has an interesting tool for reviewing the debate. Alongside the actual video, there is a transcription (which you can click on to go to that section of the video), a search tool (that counts the number of usages by each candidate), a topic segmentation view, and even a fact checker that links to corrections.
