“Using total vari­a­tion based energy min­imi­sa­tion we address the recov­ery of a blurred (con­vo­luted) one dimen­sional (1D) bar­code. We con­sider func­tion­als defined over all pos­si­ble bar­codes with fidelity to a con­vo­luted sig­nal of a bar­code, and reg­u­larised by total vari­a­tion. Our fidelity terms con­sist of the L^2 dis­tance either directly to the mea­sured sig­nal or pre­ceded by decon­vo­lu­tion. Key length scales and para­me­ters are the X-​​dimension of the under­ly­ing bar­code, the size of the sup­ports of the con­vo­lu­tion and decon­vo­lu­tion ker­nels, and the fidelity para­me­ter. For all func­tion­als, we estab­lish regimes (suf­fi­cient con­di­tions) wherein the under­ly­ing bar­code is the unique min­imiser. We also present some numer­i­cal exper­i­ments sug­gest­ing that these suf­fi­cient con­di­tions are not opti­mal and the energy meth­ods are quite robust for sig­nif­i­cant blurring.”

“The YouTube Non­profit Pro­gram pro­vides for extra ben­e­fits like brand­ing capa­bil­i­ties, increased upload­ing capac­ity, and call-​​to-​​action over­lays. Non-​​profits can use the call-​​to-​​action fea­ture to drive sign-​​ups, dona­tions, web­site traf­fic, and any other response in which users take action. This fea­ture was effec­tively used by the World Food Pro­gramme to raise $36,000 on World Food Day with this video.…”

“Often­times, you’ll want to fit a line to a bunch of data points to make it eas­ier to spot pat­terns or rela­tion­ships. It might be obser­va­tions over time or it might be two vari­ables that are pos­si­bly related. In either case, a scat­ter plot just might not be enough to see any­thing use­ful. This tuto­r­ial will show you how to graph a fit­ted line, or loess curve, to such a scat­ter plot.”

“The study of high-​​dimensional dif­fer­en­tial equa­tions is chal­leng­ing and dif­fi­cult due to the ana­lyt­i­cal and com­pu­ta­tional intractabil­ity. Here, we sig­nif­i­cantly improve the speed of wave­form relax­ation (WR), a method to sim­u­late high-​​dimensional differential-​​algebraic equa­tions. This new method termed adap­tive wave­form relax­ation (AWR) is tested on a com­mu­ni­ca­tion net­work exam­ple. Fur­ther we ana­lyze dif­fer­ent heuris­tics for com­put­ing graph par­ti­tions tai­lored to adap­tive wave­form relaxation.”

“In a nine-​​month study, four fic­ti­tious com­pa­nies invented by the account­abil­ity office also sought Ener­gyS­tar sta­tus for some con­ven­tional devices like dehu­mid­i­fiers and heat pump mod­els that existed only on paper. The fake com­pa­nies sub­mit­ted data indi­cat­ing that the mod­els con­sumed 20 per­cent less energy than even the most effi­cient ones on the mar­ket. Yet those appli­ca­tions were mostly approved with­out a chal­lenge or even ques­tions, the report said.”

“Copy­right for Librar­i­ans is a joint project of the Berk­man Cen­ter for Inter­net & Soci­ety and Elec­tronic Infor­ma­tion for Libraries (eIFL), a con­sor­tium of libraries from 50 coun­tries in Africa, Asia and Europe. The goal of the project is to pro­vide librar­i­ans in devel­op­ing and tran­si­tional coun­tries infor­ma­tion con­cern­ing copy­right law. More specif­i­cally, it aspires to inform librar­i­ans con­cern­ing:
copy­right law in gen­eral
the aspects of copy­right law that most affect libraries
how librar­i­ans in the future could most effec­tively par­tic­i­pate in the processes by which copy­right law is inter­preted and shaped.”

“Go there, read it, and under­stand why (just like news­pa­per report­ing and books) web con­tent costs money and must be paid for or sub­si­dized. Either that or it must serve some sec­ondary ben­e­fit that brings in the bucks: for instance, a free web design blog might lead to pay­ing web design gigs for its author, or so they say.

Then read Part Two: Pay­ing For It, where Kissane con­sid­ers each of these meth­ods of sub­si­diz­ing con­tent “and how they relate to our work as con­tent and edi­to­r­ial strategists.””

“The require­ments for build­ing R vary, depend­ing whether the build machine is an Intel-​​based or PowerPC-​​based Mac and whether uni­ver­sal build is desired. The fol­low­ing descrip­tion shows the min­i­mum require­ments for build­ing R.…”
