Amaya Toman Tsoka ilo, mbiri yaukadaulo imaphatikizansopo zochitika zomvetsa chisoni. Tidzakumbukira m'modzi wa iwo mu gawo lamasiku ano la "mbiri" yathu - pa Januware 7, 1943, woyambitsa Nikola Tesla anamwalira. Mu gawo lachiwiri la nkhaniyi, tipita patsogolo zaka makumi awiri ndikukumbukira kukhazikitsidwa kwa pulogalamu ya Sketchpad.

Nikola Tesla anamwalira (1943)
Pa Januware 7, 1943, Nikola Tesla, woyambitsa, wasayansi komanso wopanga makina amagetsi, anamwalira ku New York ali ndi zaka 86. Nikola Tesla anabadwa pa July 10, 1856 ku Smiljan kwa makolo a ku Serbia. Nditamaliza maphunziro a galamala, Nikola Tesla anayamba kuphunzira physics ndi masamu ku Graz. Kale pa maphunziro ake, cantors anazindikira luso Tesla ndipo anamuthandiza mu kuyesera physics. M'chilimwe cha 1883, Tesla adamanga injini yoyamba ya AC. Mwa zina, Nikola Tesla anamaliza semester imodzi yophunzira ku Prague's Charles University, kenako adachita kafukufuku wamagetsi ku Budapest, ndipo mu 1884 adakhazikika ku United States. Apa iye ankagwira ntchito pa Edison Machine Works, koma atatha kusagwirizana ndi Edison, iye anayambitsa kampani yake yotchedwa Tesla Electric Light & Manufacturing, yomwe inkagwira ntchito yopanga ndi patenting ya kusintha kwa nyali za arc. Koma Tesla adachotsedwa ntchito pakampaniyo patapita nthawi, ndipo patatha zaka zingapo adathandizira ndi zomwe adapeza pakupanga injini ya AC induction motor. Anapitiliza kudzipereka kwambiri pakufufuza ndi zopanga, ndi zovomerezeka pafupifupi mazana atatu pangongole yake.
Kuyambitsa Sketchpad (1963)
Pa January 7, 1963, Ivan Sutherland anayambitsa Sketchpad - imodzi mwa mapulogalamu oyambirira a makompyuta a TX-0 omwe amalola kusokoneza mwachindunji ndi kugwirizana ndi zinthu pakompyuta. Sketchpad imatengedwa kuti ndi imodzi mwazinthu zofunika kwambiri pamapulogalamu apakompyuta. Sketchpad idapeza kugwiritsidwa ntchito kwake makamaka pogwira ntchito ndi zojambula zasayansi ndi masamu, pambuyo pake idakhala maziko azithunzi zamakompyuta, mawonekedwe a makina ogwiritsira ntchito makompyuta ndi mapulogalamu omwe ali pakati paukadaulo wamakono.
