Tech directions: IkaScope

They call it the IkaScope. “Robust and reliable analog front end, Measuring signals with IkaScope is quick, easy and intuitive. Sampling rate 200 MSPS; Bandwidth 25 MHz; Memory 4000 pts; Input range ± 40V; Coupling AC / DC; Refresh rate 200 FPS*.” At this time, it’s a gleam in the designer’s eye so who knows […]

Vox on the lost: by then it is too late.

Chronic unemployment and a life that degrades from something to nothing is a tragedy that is individual and social. It can be top down, as is being shown right now in Venezuela or it can be bottom up as seen in a series of personal essays in Vox Trending Topics. In thinking about these experiences, […]

Modern software development – not your granddaddy’s computer no more

Paul Galvin talks about Overcoming Functional Programming’s Cognitive Dissonance Issues (for sticklers like me). I don’t know how much you’re like me, but if you are, you can get bogged down in the specific meaning of words, concepts, definitions and how these apply to the real world. I can personally have a difficult time bridging […]

One thing leads to another: Time for the pi, GPS, ntp, ESP8266, microPython, Lua

The pi boots without any calendar time reference. If it comes up on the I’net, it uses ntp to set the clock but offline it has no reference. Things work pretty well by just ignoring the clock and I could just set it manually if need be. The other options would be to use a […]

The first computer was a $6-million-dollar […]

Scientific illiteracy

A good case of illiteracy over at CNN Money: Why more people are suddenly dying on U.S. roads by Matt McFarland. But traffic safety experts said there was no single culprit for the surge in motor vehicle deaths. Smartphone use, cheaper gas prices, climate change and a strong economy all play a role. “It’s a very […]

Computers, microcontrollers, cost points, features

I see Seeed Studio has a special on a Raspberry Pi 7″ Touchscreen Display for $60. Add $40 for the SBC and another $10 for a case and memory and on down the line and you’ve got to wonder about cost effectiveness. You can get a ready to run 7″ tablet for under $50 and […]

Gravity waves. 5 Sigma results

The announcement indicates that gravity waves have been detected. The source of the waves is the collision of two black holes each with a mass of tens of times that of the sun. In the collision, an amount of mass was lost equivalent to several times that of the sun. This loss of mass was […]

Standards, squashing the pile, and maturing technology

Paul Venezia poses the question: Countless IT admin tools depend on these technologies. Do you have a plan to keep yours working?. What prompted the question goes back to browser incompatibilities, browser limitations, and efforts to provide services via web browsers. A quick glance around an IT infrastructure of any size will reveal a rich […]
