Anatomy of a Computer Virus: A 3.5 Minute Primer

Last week, Cit­i­group admit­ted that hack­ers exposed the pri­vate finan­cial data of more than 360,000 cus­tomer accounts. Mean­while, in an unre­lat­ed attack, Lulz Secu­ri­ty man­aged to bring down the CIA web­site, and this week they’ve declared war on gov­ern­ment agen­cies around the world.

Now might be a good time to beef up on your knowl­edge of mal­ware, cyber­crime, and cyber­war­fare, start­ing with Stuxnet, a com­put­er virus that was launched against Iran­ian nuclear infra­struc­tures in 2010 (most like­ly by the U.S.). For a quick primer on Stuxnet, check out Anato­my of a Com­put­er Virus. It’s only three and a half min­utes long, but you’ll learn enough to decide whether or not to set your lap­top on fire, sell every­thing you own, and run scream­ing for the Yukon.

For a more detailed explo­ration of the virus, watch Crack­ing Stuxnet, A 21st-Cen­tu­ry Cyber Weapon, a TED talk by cyber-secu­ri­ty expert Ralph Langn­er. Dis­claimer: It won’t nec­es­sar­i­ly put you at ease — the pre­sen­ter clos­es by thank­ing Mr. Langn­er for “scar­ing the liv­ing day­lights out of us.”

The Next-Generation Digital Book

There will be a day — maybe it’s already here; maybe it was always here — when the Kin­dle will look incred­i­bly retro. Mike Matas, once a design­er of user inter­faces at Apple and now co-founder of Push Pop Press, may make that day of visu­al reck­on­ing come soon­er rather than lat­er. The demo above (which is eas­i­ly worth a thou­sand words) lets you peer into the near future.. Text, images, audio, video and inter­ac­tive graph­ics — they’ll come togeth­er in a seam­less read­ing expe­ri­ence, mak­ing the tra­di­tion­al ebook look entire­ly one dimen­sion­al. You can down­load the book on dis­play, Al Gore’s “Our Choice,” on iTunes here.

Inventing the Digital Camera: A Short Portrait of Steven Sasson

Work­ing for East­man Kodak back in 1975, Steven Sas­son, an elec­tri­cal engi­neer by train­ing, was tasked with build­ing a cam­era that used sol­id state elec­tron­ics and sol­id state imagers to cap­ture opti­cal infor­ma­tion. Or, put very sim­ply, he was asked to build the first dig­i­tal cam­era. And he did just that.

In the lat­est of a series of short doc­u­men­taries on con­tem­po­rary inven­tors, pho­tog­ra­ph­er David Fried­man sat down with Sas­son at Kodak’s head­quar­ters in Rochester, NY and revis­it­ed the tech­ni­cal and cul­tur­al chal­lenges faced by the inven­tor. So far, Fried­man has pro­duced 32 por­traits of inven­tors, and, for the most part, you’ll rec­og­nize the inven­tors’ cre­ations soon­er than their names. You can access the full col­lec­tion of por­traits here.

Every Step You Take, They’ll Be Tracking You

Malte Spitz, a mem­ber of the Green Par­ty in Ger­many, sued Deutsche Telekom and forced the com­pa­ny to hand over six months of record­ed cell phone data. The results were fair­ly eye open­ing.

Dur­ing a five month peri­od, DT tracked Spitz’s loca­tion and phone usage 35,000 times. If that sounds like a lot, you’re right. And it looks even worse when you visu­al­ize the data. Zeit Online took this geolo­ca­tion data and com­bined it with pub­licly-avail­able infor­ma­tion relat­ing to Spitz’s polit­i­cal life (e.g., his Twit­ter feeds and blog entries) and pro­duced a screen­cast that doc­u­ments two days in the life of the Green Par­ty politi­cian. The YouTube video above traces his steps. But the visu­als on the Zeit site let you track Spitz’s move­ments around Ger­many with fin­er pre­ci­sion. The moral of the sto­ry: Every step you take, your tel­co is like­ly track­ing you, whether you give con­sent or not. The New York Times has more on the sto­ry…

The Quadrocopter Opera

Physics gets its own lit­tle opera. And you’ll nev­er look at quadro­copters, those ball jug­gling robots, in quite the same way. Nice work “Opera­man­da”…

Scifoo: How Would You Spend a Billion Dollars?

Sci­foo is an annu­al “uncon­fer­ence” c0-host­ed in Moun­tain View, Cal­i­for­nia by Google, O’Reil­ly Media and Nature pub­lish­ing. It’s par­tic­i­pant-dri­ven, cross-pol­li­nat­ing, and high­ly unstruc­tured, rely­ing more on brain­storms and erasable white boards than Pow­er­Point pre­sen­ta­tions and lec­ture halls. Accord­ing to Nature’s page for Sci­foo 2011:

200 lead­ing sci­en­tists, tech­nol­o­gists, writ­ers and oth­er thought-lead­ers will gath­er once more at the Google­plex for a week­end of unbri­dled dis­cus­sion, demon­stra­tion and debate.

The event is invi­ta­tion-only, but if your own posi­tion as glob­al thought-leader has not yet been rec­og­nized, you can take com­fort in these engag­ing short videos from past Sci­foo con­fer­ences. In addi­tion to film­ing the oblig­a­tory gen­er­al overview, Nature also asked some of the atten­dees – includ­ing a cli­mate sci­en­tist, an astro­bi­ol­o­gist, and a Nobel lau­re­ate in physics – for short answers on spe­cif­ic top­ics, like fears for the futurepre­dic­tions for the next decade and our per­son­al favorite ques­tion: “If you had $1 bil­lion to spend on just one project, what would it be?”

Some­thing that should inspire teach­ers: A good chunk of these experts’ dream projects involved push­es for wide­spread edu­ca­tion reform and dis­sem­i­na­tion of exist­ing knowl­edge, rather than financ­ing for advances in their par­tic­u­lar spe­cial­ties. We par­tic­u­lar­ly liked skep­tic Michael Sher­mer’s vision of world­wide crit­i­cal think­ing pro­grams that would teach stu­dents “not what to think, but how to think.” (2:34)

Evgeny Morozov Animated: The Dark Side of Internet Freedom

RSA has released its lat­est ani­mat­ed video, and this time it fea­tures Evge­ny Moro­zov, the Belarus-born researcher, who takes the con­trar­i­an posi­tion that the inter­net can often inhib­it (rather than pro­mote) democ­ra­cy, espe­cial­ly with­in author­i­tar­i­an con­texts like Chi­na and Iran. And what fol­lows (above) is a more sober­ing talk about how author­i­tar­i­an regimes use the web to sup­press civic engage­ment and fledg­ling democ­ra­cy move­ments. This clip is part of a longer 27 minute lec­ture (see full ver­sion here) that peers into “the dark side of inter­net free­dom,” a phrase that hap­pens to be the sub­ti­tle of Moro­zov’s new book.

Moro­zov is cur­rent­ly a vis­it­ing schol­ar in the Lib­er­a­tion Tech­nol­o­gy Pro­gram at Stan­ford, and if you’re won­der­ing how he looks at tech­nol­o­gy and the role it played in Egyp­t’s rev­o­lu­tion, you can watch a quick clip here.

Visualizing WiFi Signals with Light

Have you ever won­dered what the WiFi sig­nal looks like around your office, school, or local cafĂ©? In this video, Timo ArnallJørn Knut­sen, and Einar Sneve Mar­t­i­nussen show you the invis­i­ble. And they pulled this off by build­ing a WiFi mea­sur­ing rod, mea­sur­ing four meters in length, that can visu­al­ize WiFi sig­nals around Oslo, Nor­way with the help of long expo­sure pho­tog­ra­phy.

What’s fas­ci­nat­ing to see is how the WiFi sig­nals vary across the city. Away from res­i­den­tial build­ings, the drop-off in WiFi strength is steep. On the oth­er hand, the WiFi sig­nal is dense around com­mer­cial and aca­d­e­m­ic build­ings. The amaz­ing visu­al­iza­tion gives us a glimpse into the com­plex rela­tion­ships between WiFi net­works and the phys­i­cal envi­ron­ments under­pin­ning them. For a deep­er read about this project, see this blog post.
