After years of buildup, the Olympics are about to kick off tomorrow in Beijing. As Shamus McGillicuddy reports, streaming Olympics video will drain corporate bandwidth. This year’s games are going to put substantial, perhaps even unprecedented, strain upon the Internet backbone. NBC plans to to stream more than 2,200 hours of live video coverage online.

CBS took a similar approach to “March Madness” this spring, streaming all 64 games of the NCAA mens’ basketball tournament.  Network administrators have similar challenges now in deciding where and whether to block users from accessing NBC.com, capping bandwidth use or engaging in a little proactive traffic shaping.

Personally, I like the suggestion made in Shamus’s story by Eileen Haggerty, director of product marketing with NetScout:

“An IT organization could set up a PC with a large-screen monitor in the office cafeteria that would run streaming video of the games. Instead of having 15 people sitting at their desks sucking up bandwidth individually, a savvy network administrator could bring all those people together to watch the Olympics during their break.”

Let’s assume for a moment, however, that you aren’t a bandwidth-conscious CTO and would like to be able to keep current on the standings in your favorite events or athletes. (Or that you believe setting up a few televisions is a handy low-tech hack.)

Thanks to Gina’s post on Lifehacker,Watch the Olympics Online, I found Wired’s excellent How-To Wiki for Watching the Olympics Online. (As you might expect, this link has been climbing the charts on the most popular page at delicious).

As the wiki notes, you can catch up to four different livestreams and more than 3,000 hours of on-demand at NBCOlympics.com.

World-wide, there also many other websites streaming Games footage:  CCTVOlympics.com in mainland China, BBC Sports in the U.K., Yahoo7 in Australia or CBC Olympics in Canada.

There’s a catch, however, to the livestreaming, on-demand video goodness: In most cases, users in the United States will be blocked from viewing the footage on any site but NBC.

If you’re savvy enough to follow the advice at Metafilter by setting up a proxy server or using Anonymizer, you should be able to get around location restrictions.

It’s a cinch that the millions of broadcast viewers will be recording and uploading events to YouTube on their own, of course.  NBC has tried to get out in front of the inevitable wave by partnering with Google, with plans to provide 3 hours of highlights and wrap-ups to a dedicated channel onYouTube.

As the authors of the Wired wiki note (nice work, applian, apardoe, mosesofmason and snackfight!), BitTorrent is also an option for watching events after the fact, though P2P files sharing on your corporate network may land you in more hot water than simply streaming the video, given the various serious security risks involved.

What the wiki doesn’t note is what is lying under the hood over at NBCOlympics.com. NBC has partnered with MSN to stream the Olympics using Silverlight, in what will be far and away the biggest test for Microsoft’s alternative to Flash to date.

Anyone that wants to watch the Olympics will have to download and install the Silverlight plug-in, a process that certain to test out exactly how ready for “prime time” the technology is for streaming rich media online. Of special note is the fact that Silverlight encrypts a videostream, which will make recording the events considerably harder (if not impossible).

As a result, tech pundits, geeks and network executives will no doubt be watching the race to crack the streams and distribute unauthorized video nearly as closely as the games themselves.

Enjoy the Olympics!

Professor Merrick Furst, associate dean at the College of Computing at Georgia Tech, explains how botmasters use zombie armies for financial gain. Furst estimates that about 7% of all Internet traffic is zombie. Kraken, today’s Word of the Day, is now reported to be the largest botnet in the world, with over 400,000 machines infected.

Video: FBI can listen even when a cellphone is turned off

Fox News aired a report in 2006 that described how the FBI can turn on the mic on a cellphone and eavesdrop — even if the phone is turned off.

Today’s Word of the Day, government Trojan, describes efforts by various governments to covertly survail traffic of all kinds to and from suspect hard drives, including VoIP, cellphones and email.

These kinds of measures are only likely to increase as groups of all stripes turn to the Web to organize and communicate about activity the government wants to monitor. I find the “analog hacks” used here intriguing. VoIP or cellphone conversations and email messages may be encrypted during transmission but if an agency can record a target on the microphone or by using a keylogger, even quantum encryptography could be sidestepped.

Hacker or cracker?

Posted by: Ivy Wigmore
commentary, hacks, conversation, hacking, controversy, word meanings

Throughout the years I’ve been writing and editing on WhatIs, I don’t think there’s been another issue that’s cropped up as often or been as gnarly to try to settle as the question of whether a person who attacks computers and networks is a hacker or a cracker.

Just about everyone but the serious geeks uses hacker to mean an attacker but anytime we do we get notes from readers to the effect that a malicious hacker is a cracker and a hacker is just someone with mad computer skills. Furthermore, they feel that we should be upholding proper usage and not letting standards slide. On the other hand, when we’ve used “cracker,” we often get notes asking if we don’t mean “hacker” and suggesting that we might want to think about using the same term everone else does.

I’ll admit I’ve often tried to skirt the issue by using “attacker.” But the time comes when an editor has to take a stand. Especially in the wake of several years of wishy-washy, indeterminate indecision. So. Decision time. Let’s see what everyone else says…

Wikipedia has a fairly extensive entry for hacker. The article starts out by defining a hacker as “a person who illegally breaks into computer and network systems” but links to a better page for hacker definition controversy.

Alpha hacker Eric S. Raymond weighs in authoritatively on the topic in his article, How to become a hacker:

There is another group of people who loudly call themselves hackers, but aren’t. These are people (mainly adolescent males) who get a kick out of breaking into computers and phreaking the phone system. Real hackers call these people ‘crackers’ and want nothing to do with them. Real hackers mostly think crackers are lazy, irresponsible, and not very bright, and object that being able to break security doesn’t make you a hacker any more than being able to hotwire cars makes you an automotive engineer. Unfortunately, many journalists and writers have been fooled into using the word ‘hacker’ to describe crackers; this irritates real hackers no end.

The basic difference is this: hackers build things, crackers break them.

There’s much more in Raymond’s FAQ-style article, including:

The Hacker Attitude

1. The world is full of fascinating problems waiting to be solved.

2. No problem should ever have to be solved twice.

3. Boredom and drudgery are evil.

4. Freedom is good.

5. Attitude is no substitute for competence.

On the other hand, you can also find support for the use of hacker as a synonym for cracker. According to wordorigins.org, that usage goes back to the November 20, 1963 issue of The Tech, the M.I.T. student paper, where it was used to refer to breaking into the phone system:

There are those that claim that hacker should not mean someone who maliciously invades computer systems, and that it really means someone proficient in computer use. But this is not the history of the term. Hacking from its beginnings at M.I.T. has always been associated with using technology to subvert institutional systems for personal use. Besides, the meanings of words are determined by usage, not etymology. So if people use hacker to mean someone who breaks into computer systems, that’s what it means.

So, the way I see it, there are a number of fairly compelling arguments for either side, chief among them being:

• Eric Raymond says a hacker is defined by skill and good intention. And everybody loves Eric Raymond.
• The earliest reference to skill-based, non-malicious technology hacking that I could find traces it back to ham radio operators in the fifties, predating the MIT paper cited on wordorigins.
• However, as wordorigins correctly points out, common use is what drives definition. So if people use hacker to mean cracker, eventually that’s what it will mean.
• And yet… cracker is unambiguous. If one uses cracker in this context, people get it. So if we use “hacker” to mean a highly computer-literate geek and “cracker” to mean an attacker of whatever skill level…

Sigh. ‘Round and round and round it goes. I’m just not sure. I’d love some input. What do you think? ~ Ivy Wigmore
