Imag­ine dial­ing a phone num­ber by hav­ing to look up each dig­it one at a time in the phone book. Nor­mal­ly, you look up the num­ber and remem­ber all sev­en dig­its long enough to get it dialed. Even with one dig­it at a time, you would have to remem­ber each dig­it long enough to get […]

one-year-after-switching-from-java-to-go

I always told people memory is cheap, black magic is OK and efficiency doesn’t matter in most cases, but boy, how wrong was I… My Java journey started back in 2011 (14 years ago – wow) when I started studying computer science at the Vienna University of Technology.

This discussion prompted me to conduct a detailed analysis of the potential cost savings associated with owning an EV, particularly focusing on fuel savings and overall cost return. In this article, I […]

Catalytic Computing Taps the Full Power of a Full Hard Drive

catalytic-computing-taps-the-full-power-of-a-full-hard-drive

“Obviously” is a dangerous word, even in scenarios that seem simple. Suppose, for instance, you need to do an important computation. You get to choose between two computers that are almost identical, except that one has an extra hard drive full of precious family photos. It’s natural to assume that the two options are equally […]

Tristan Davey’s Punch Card Archive

Punched cards were once a ubiquitous part of accounting, data collection and early computing. At their peak of use, in the 1950s and 60s, hundreds of companies around the world printed millions of punch cards every month.

Spread across NASA’s headquarters and 10 field centers, which dot the United States from sea to sea, the space agency has had a workforce of nearly 18,000 civil servants. However, by the end of today, that number will have shrunk by about 10 percent since the beginning of the second Trump administration four weeks ago. […]
