Japonský výzkumný ústav RIKEN zahajuje šetření ve věci buněčné revoluce v tvorbě kmenových buněk z libovolné dospělé buňky pouhým namočením do mírně kyselého roztoku. Na adresu Japonky se snesla kritika za nesrovnalosti včlánku v časopisu Nature věnovanému STAP buňkám.
narazil som na toto hodinove video, a napriek tomu ze neznasam videa, toto povazujem za velmi prinosne. pre mna to je zhrnutie pocitov a nazorov ktore som intuitivne "tusil", ale v tom videu ich ten chlapik povie nahlas a je to pekne explicitne vyslovene a presvedcive.
PiezoMAT proposes a new technology of high-resolution fingerprint sensors based on a matrix of interconnected piezoelectric nanowires (NWs). The sub-micron dimension of NWs allows for high spatial frequency sampling of every fingerprint feature, enabling extremely reliable fingerprint differentiation through detection of the smallest minutiae (pores and ridge shapes).
je to zoznam "odporucani do zivota" (patterns) pre vyvojarov ktory sa chcu zlepsovat. je to povodne urcene najma pre zacinajucich programatorov, ale pride mi to nadcasove a je tasm vela napadov a odporucani na celu "programatorsku" karieru. odporucam kazdemu kto programuje, knizka ma dobru granularitu a cita sa lahko.
if you don't pass a header, by default Ruby will pass the header that will tell the external service that your app is ok with a Gzipped response (which is obviously wrong)
It speeds up development by keeping your application running in the background so you don't need to boot it every time you run a test, rake task or migration.
the translated strings are stored on the heap, where the garbage collector must scan over the objects on every run (at least in the case of Ruby MRI). For a mature process with all the translations loaded, this is almost 1 million objects! Second, each process has its own copy of the strings.
