Learn to Code with Harvard’s Intro to Computer Science Course And Other Free Tech Classes

I’ll con­fess, when it comes to com­put­ers, I’m pret­ty much strict­ly a user. And these days, with the poten­tial free­dom and cre­ative­ly afford­ed by open access soft­ware, the end­less hacks for vir­tu­al­ly every­thing, and the avail­abil­i­ty of free online com­put­er class­es, that seems like kind of a lame admis­sion. So I’m tempt­ed to rec­ti­fy my pro­gram­ming igno­rance by push­ing through what promis­es to be a rig­or­ous intro to com­put­er sci­ence, CS50, Harvard’s intro­duc­to­ry course for both majors and non-majors alike. The course offers a broad knowl­edge base to build on, as you can see from the descrip­tion below:

Top­ics include abstrac­tion, algo­rithms, encap­su­la­tion, data struc­tures, data­bas­es, mem­o­ry man­age­ment, secu­ri­ty, soft­ware devel­op­ment, vir­tu­al­iza­tion, and web­sites. Lan­guages include C, PHP, and JavaScript plus SQL, CSS, and HTML. Prob­lem sets inspired by real-world domains of biol­o­gy, cryp­tog­ra­phy, finance, foren­sics, and gam­ing. Designed for con­cen­tra­tors and non-con­cen­tra­tors alike, with or with­out pri­or pro­gram­ming expe­ri­ence.

Har­vard has made this course avail­able free to anyone—via YouTubeiTunes, and the course page—with a series of lec­tures filmed dur­ing the Fall 2011 semes­ter. The class is led by David J. Malan, an enthu­si­as­tic young pro­fes­sor and Senior Lec­tur­er on Com­put­er Sci­ence at Har­vard, and him­self a prod­uct of Harvard’s Com­put­er Sci­ence pro­gram. Pro­fes­sor Malan has also offered Harvard’s CS50 as a MOOC through edX. In the intro­duc­to­ry lec­ture to CS50 (above), Malan promis­es that “this is one of those rare cours­es that actu­al­ly squeezes your brain so much and your sched­ule so much that by the end of the semes­ter you actu­al­ly feel smarter.”

Pro­fes­sor Malan has become some­thing of a hot shot at Har­vard. His mission—to make com­put­er sci­ence more acces­si­ble and far less daunt­ing. He’s done this in part by gen­er­ous­ly mak­ing sev­er­al of his cours­es avail­able free online to non-Har­vard stu­dents. In addi­tion to CS50, Malan offers the fol­low­ing cours­es for those who want to pur­sue pro­gram­ming or web design fur­ther:

And if you still need some sell­ing on the val­ues and virtues of com­put­er sci­ence, watch Malan below deliv­er an inspir­ing talk called “And the Geek Shall Inher­it the Earth” at Har­vard Thinks Big 2010 (Harvard’s ver­sion of TED Talks).

We’ve added Har­vard’s CS50 to the Com­put­er Sci­ence sec­tion of our list of 750 Free Online Cours­es and our list of 150 Free Busi­ness Cours­es.

Start Your Startup with Free Stanford Courses and Lectures

Last spring, Ken Aulet­ta wrote a pro­file of Stan­ford Uni­ver­si­ty in the pages of The New York­er, which start­ed with the ques­tion: “There are no walls between Stan­ford and Sil­i­con Val­ley. Should there be?” It’s per­haps an unavoid­able ques­tion when you con­sid­er a star­tling fact cit­ed by the arti­cle. Accord­ing the uni­ver­si­ty itself, five thou­sand com­pa­nies “trace their ori­gins to Stan­ford ideas or to Stan­ford fac­ul­ty and stu­dents.” The list includes tech giants like Google, Hewlett-Packard, Yahoo, Cis­co Sys­tems, Sun Microsys­tems, eBay, Net­flix, Elec­tron­ic Arts, Intu­it, Sil­i­con Graph­ics, LinkedIn, and E*Trade. And stay tuned, there’s more to come.

Stan­ford is one of Amer­i­ca’s lead­ing incu­ba­tors, and the rear­ing of young entre­pre­neurs does­n’t take place by mere osmo­sis. No, Stan­ford stu­dents can take cours­es focused on entre­pre­neur­ship, which give them access to sea­soned entre­pre­neurs and financiers. If you head over to eCorner, short for Entre­pre­neur­ship Cor­ner (WebiTunesYouTube), you can watch “2000 free videos and pod­casts fea­tur­ing entre­pre­neur­ship and inno­va­tion thought lead­ers” who have paid vis­its to Stan­ford. Per­haps you’ll rec­og­nize a few of the names: Mark Zucker­bergLar­ry PageMaris­sa May­er? Reid Hoff­man (above)?

Or, if you go to YouTube and iTunes, you’ll gain access to entire cours­es ded­i­cat­ed to teach­ing stu­dents the mod­ern art of start­ing star­tups. Two cours­es (both housed in our col­lec­tion of 650 Free Online Cours­es and our col­lec­tion of 150 Free Online Busi­ness Cours­es) war­rant your atten­tion. First, Chuck Eesley’s course, Tech­nol­o­gy Entre­pre­neur­ship (YouTube — iTunes Video) intro­duces stu­dents to “the process used by tech­nol­o­gy entre­pre­neurs to start com­pa­nies. It involves tak­ing a tech­nol­o­gy idea and find­ing a high-poten­tial com­mer­cial oppor­tu­ni­ty, gath­er­ing resources such as tal­ent and cap­i­tal, fig­ur­ing out how to sell and mar­ket the idea, and man­ag­ing rapid growth.” The course fea­tures 28 video lec­tures in total.

Once you have a broad overview, you can dial into an impor­tant part of get­ting a new ven­ture going — rais­ing cap­i­tal. Hence the course Entre­pre­neur­ship Through the Lens of Ven­ture Cap­i­tal (iTunes Video — YouTube), a course cur­rent­ly tak­ing place at Stan­ford that “explores how suc­cess­ful star­tups nav­i­gate fund­ing, man­ag­ing, and scal­ing their new enter­prise.” It fea­tures guest speak­ers from the VC world that fuels Sil­i­con Val­ley.

It goes with­out say­ing that Stan­ford offers many world-class cours­es across oth­er dis­ci­plines, from phi­los­o­phy and physics to his­to­ry and lit­er­a­ture. You can find 68 cours­es from Stan­ford in our ever-grow­ing col­lec­tion of Free Cours­es Online.

Simulate the Damage Caused by Comet and Asteroid Collisions with Impact: Earth!

impact earthOn Fri­day, the world had its eyes focused on the big aster­oid fly­by. For weeks, we knew it was com­ing, and we watched it buzz by with mild curios­i­ty. But, that same day, we were all caught off guard by a ten-ton mete­orite that blast­ed into the Siber­ian town of Chelyabin­sk, injur­ing 1,200 peo­ple and caus­ing con­sid­er­able struc­tur­al dam­age. (Watch footage here.) This abrupt and unex­pect­ed event has giv­en gov­ern­ments a rea­son to start tak­ing the risk of aster­oid impacts a bit more seri­ous­ly. And it might renew inter­est in a tool cre­at­ed by sci­en­tists at Pur­due Uni­ver­si­ty and Impe­r­i­al Col­lege Lon­don in 2010.

In a nut­shell, Impact: Earth! is an inter­ac­tive tool that lets any­one cal­cu­late the dam­age a comet or aster­oid would cause if it hap­pened to col­lide with our plan­et. You can cus­tomize the size and speed of the incom­ing object, and then find out if mankind sur­vives. (Usu­al­ly it does.) A grainy primer appears below. You can enter the web­site and start run­ning your own sce­nar­ios right here.

From the Annals of Optimism: The Newspaper Industry in 1981 Imagines its Digital Future

“Imag­ine, if you will, sit­ting down to your morn­ing cof­fee, turn­ing on your home com­put­er to read the day’s news­pa­per.” A flam­boy­ant­ly spec­u­la­tive-sound­ing notion, no doubt, were you watch­ing this tele­vi­sion news broad­cast back when it aired in 1981. A pro­duc­tion of San Fran­cis­co’s KRON, the seg­ment takes a look at how the city’s news­pa­pers, dis­play­ing admirable far­sight­ed­ness, were then “invest­ing a lot of mon­ey to try and get a ser­vice just like that start­ed.” We see North Beach res­i­dent Richard Hal­lo­ran (he of  the immor­tal­ly meme-wor­thy onscreen iden­ti­fi­er, “Owns Home Com­put­er”) dial­ing, on his rotary tele­phone, “a local num­ber that will con­nect him with a com­put­er in Colum­bus, Ohio.” We also see the edi­tors of the San Fran­cis­co Exam­in­er “pro­gram­ming today’s copy of the paper into that same Ohio com­put­er.” Hal­lo­ran plops the phone’s receiv­er into his modem’s acoustic cou­pler, pre­sum­ably pours his morn­ing cof­fee, and down­loads the day’s paper — which takes two hours, at a cost of five dol­lars an hour.

“This is only the first step in news­pa­pers by com­put­er,” says KRON sci­ence reporter Steve New­man. “Engi­neers now pre­dict the day will come when we get all out news­pa­pers and mag­a­zines by home com­put­er.” We see footage of a tra­di­tion­al news­pa­per ven­dor: “But that’s a few years off, so for the moment, at least, this fel­low isn’t wor­ried about being out of a job.” That day came over a decade ago, and that fel­low sure­ly wor­ries now, as do the pub­lish­ers of his wares. We who start each day read­ing the news on our “home com­put­ers” laugh at the news­pa­per indus­try’s evi­dent hubris­tic self-destruc­tion by its fail­ure to under­stand the inter­net, much less engage with it. But this report shows us that cer­tain papers — the eight that Hal­lo­ran’s menu offered him, at least — seem­ing­ly had their eyes on the ball long before we did. Do we see here an indus­try sow­ing the seeds of its own inevitable destruc­tion, or evi­dence that things could have turned out dif­fer­ent­ly?

Watch the New Pirate Bay Documentary Free Online

Last Fri­day night, TPB AFK: The Pirate Bay Away From Key­board pre­miered at the Berlin Film Fes­ti­val. Moments lat­er, the indie doc­u­men­tary became freely avail­able online, which left the film’s direc­tor, Simon Klose, grin­ning, not grum­bling. It makes sense when you con­sid­er the premise of the film. Pirate Bay is, of course, the web site that allows users to share media (music, movies, games, soft­ware) through a peer-to-peer file shar­ing pro­to­col, some of it copy­right­ed, some of it not. And the new film, writes Wired, doc­u­ments “the hec­tic tri­al of Pirate Bay admin­is­tra­tors Fredrik Neij, Got­tfrid Svartholm Warg, and Peter Sunde, who were even­tu­al­ly con­vict­ed in a civ­il and crim­i­nal copy­right case in Swe­den in 2009 that pit­ted them against the gov­ern­ment and the enter­tain­ment indus­try.”

Walter Cronkite Imagines the Home of the 21st Century … Back in 1967

Liv­ing room, 2001:

In 1967, exec­u­tives at CBS tele­vi­sion made a bold move and changed the net­work’s long-run­ning doc­u­men­tary series, The 20th Cen­tu­ry, from a pro­gram look­ing back at the past to one look­ing ahead to the future. The 21st Cen­tu­ry, as it was renamed, was host­ed by Wal­ter Cronkite and ran for three sea­sons. In one of the ear­ly episodes, “At Home, 2001,” which aired on March 12, 1967, Cronkite cites a gov­ern­ment report pre­dict­ing that by the year 2000, tech­nol­o­gy will have low­ered the aver­age Amer­i­can work week to 30 hours, with a one-month vaca­tion. What will peo­ple do with all that free time? In the scene above, Cronkite makes a fair­ly accu­rate pre­dic­tion of today’s state-of-the-art home enter­tain­ment sys­tems. Although the knobs and dials look a bit archa­ic, the basic prin­ci­ple is there. But what­ev­er hap­pened to that 30-hour work week?

Home office, 2001:

“Now this is where a man might spend most of his time in the 21st cen­tu­ry,” says Cronkite as he walks into the home office of the future, above. “This equip­ment will allow him to car­ry on nor­mal busi­ness activ­i­ties with­out ever going to an office away from home.”

In envi­sion­ing the office of the future as a mas­cu­line domain, Cronkite makes the same mis­take as Stan­ley Kubrick and Arthur C. Clarke of imag­in­ing tech­no­log­i­cal change with­out social change. (Remem­ber the moon shut­tle stew­ardess in 2001: A Space Odyssey?) But he oth­er­wise offers a fair­ly pre­scient vision of some of the home com­put­ing, Inter­net and telecom­mu­ni­ca­tions advances that have indeed come to pass.

Kitchen, 2001:

Cronkite’s pow­ers of pre­dic­tion fail him when he reach­es the Rube Gold­ber­gian “kitchen of 2001,” which mis­takes gra­tu­itous automa­tion for con­ve­nience. As one YouTube com­men­ta­tor said of the clip above, the only thing that resem­bles the kitchen of today is the microwave oven–and microwaves already exist­ed in 1967.

But “At Home, 2001,” is much more thought-pro­vok­ing than a few “gee whiz” pre­dic­tions about the gad­gets of the future. Cronkite inter­views the archi­tect Philip John­son and oth­er lead­ing design­ers of his day for a deep­er dis­cus­sion about the ten­sion that exists between our deep-seat­ed, basi­cal­ly agrar­i­an expec­ta­tions for a home and the real­i­ties of urban con­ges­tion and sub­ur­ban sprawl. You can watch the com­plete 25-minute pro­gram at A/V Geeks. And to read more about it, see Matt Novak’s piece at Pale­o­Fu­ture. “Can we find a com­pro­mise between our increas­ing­ly urban way of liv­ing and the pride and pri­va­cy of the indi­vid­ual home?” asks Cronkite at the end of the pro­gram. “It will take deci­sions that go beyond tech­nol­o­gy, deci­sions about the qual­i­ty of the life we want to lead, to answer the ques­tion ‘How will we live in the 21st cen­tu­ry?’ ”

Neil Gaiman Launches New Crowdsourced Storytelling Project (Sponsored by the New BlackBerry)

The tech-savvi­est among us may greet the news of a new Black­Ber­ry phone with an exag­ger­at­ed yawn, if that. But we have rea­sons not to dis­miss the lat­est iter­a­tion of Research in Motion’s flag­ship prod­uct entire­ly. The Z10 launched to record ear­ly sales in the Unit­ed Kind­gom and Cana­da. Both the device and the fresh oper­at­ing sys­tem that runs on it “rep­re­sent a rad­i­cal rein­ven­tion of the Black­Ber­ry,” writes Wall Street Jour­nal per­son­al tech­nol­o­gy critc Walt Moss­berg. “The hard­ware is decent and the user inter­face is log­i­cal and gen­er­al­ly easy to use. I believe it has a chance of get­ting RIM back into the game.” Even so, build­ing the prod­uct amounts to only half the bat­tle; now the Black­Ber­ry brand has to con­tin­ue gain­ing, and man­age to hold, cus­tomer inter­est. That’s where a cer­tain mas­ter of gain­ing and hold­ing inter­est named Neil Gaiman comes in.

Say what you will about their phones; Research in Motion’s mar­ket­ing depart­ment has shown an uncom­mon degree of lit­er­ary astute­ness, at least by the stan­dards of hard­ware mak­ers. You may remem­ber Dou­glas Cou­p­land, for instance, turn­ing up in adver­tise­ments for the Black­Ber­ry Pearl back in 2006. But the com­pa­ny has recruit­ed Gaiman—the Eng­lish author of every­thing from nov­els like Amer­i­can Gods and Cora­line to com­ic books like The Sand­man to tele­vi­sion series like Never­where to films like Mir­ror­Mask—for a more com­pli­cat­ed under­tak­ing than Cou­p­land’s. Under the aegis of Black­Ber­ry, Gaiman extends his col­lab­o­ra­tion-inten­sive work one domain fur­ther. A Cal­en­dar of Tales finds him sourc­ing ideas and visu­als from the pub­lic in order to cre­ate “an amaz­ing cal­en­dar show­cas­ing your illus­tra­tions beside Neil’s sto­ries.” The short video above recent­ly appeared as the first in a series of episodes cov­er­ing this sto­ry­telling project. Of this we’ll no doubt hear, see, and read much more before 2013’s actu­al cal­en­dar is out.

But, per­haps you’ll find it fas­ci­nat­ing to watch British singer Sivu per­form his song “Bet­ter Than He” through the prism of mag­net­ic res­o­nance imag­ing. Or, if you’ve ever spent time enveloped in an MRI machine, you’ll say the oper­a­tive word is “anx­i­ety-pro­duc­ing.” If the reports are true, Sivu spent three hours record­ing the three-minute song. Just imag­ine the amount of Ati­van and com­mit­ment that got him through…
