If you’re interested and have some time What Really Happened with Vista is an insider’s report on the internal Microsoft culture that caused them to fumble the development and release of Windows Vista.
In an interview with the NY Times, Twitter co-founder Ev Williams says Twitter’s role in Trump’s rise is ‘a very bad thing’.
Commenting on the view of Silicon Valley as the “modern Prometheus”, Williams said:
What we tend to forget is that Zeus was so pissed at Prometheus that he chained him to a rock so eagles could peck out his guts for eternity,” he said. “Some would say that’s what we deserve for giving the power of tweets to Donald Trump.
Most people are at least vaguely familiar with the early history of modern digital computers, particularly their importance in breaking the Nazi Enigma codes during WWII. Less familiar is the computing machines that preceded them.
In response to the need for more and faster computation, researchers developed a series of analog computers that did the job but were complicated and difficult to maintain. Inspired by (and in some cases actually using) the switches used to connect telephone calls, digital computers using relays were developed that used base 2 arithmetic. As useful as they were these relay computers would end up mostly being forgotten, replaced by machines based on vacuum tubes.
Let’s be honest, learning to play the guitar is hard. Like 90% of beginners quit within a year hard. This hits guitar builders like Fender right in the bottom line. So they’re coming out with lots of apps, gear and more expressly designed to help new players stick with it long enough to get some momentum going.
Still there are no guarantees. I’ve been playing guitar since I was a teen and despite decades of lessons I’m still not very good.
If you have the right setup, you can receive analog TV signals from the International Space Station. AMSAT UK has the details for the curious. This is Slow Scan Television (SSTV), so it’s more like a slide show than the video you’re used to.
Please note the Motherboard link is chock-full of inaccuracies. First of all, you don’t need any license, Amateur or otherwise, to receive RF signals (in the US or Canada, check your local regulations elsewhere). Second, while it may indeed take a week or more to receive your ham license, that’s FCC processing time after you’ve successfully passed a licensing examination. Assuming you’ll have to spend at least a little bit of time studying for the exam a week is wishful thinking.
If you’re interested in getting your license, the ARRL’s page on licensing is a good place to start.
Talk about attack surface: CERN has to keep tabs on around 40,000 bring-your-own-devices from professors, technicians, and other workers; academics and engineers also connect to systems remotely. The organization’s two main data centres in Switzerland and Hungary have around 100,000 hard-drives and 13,000 servers in total.
Then there’s the LHC’s computing grid, spread across North America, Europe, and Asia, which reprocesses data generated by the experiments. Control systems for equipment need to be secure as well, and CERN hosts around 10,000 websites.
Polymagnets are software-configurable magnetic components that can be programmed to have many different configurations of North and South poles. They’ve been around for a while it seems but they don’t seem to have made it into products.
If you’ve done anything with electronics in the past forty years or so you’ve likely come across the 555 timer IC. It’s small, simple and incredibly useful. I used one as the timing source for a “T-Bird tailights” project in a digital electronics course I took as an elective. The actual chip is fairly small and easy to understand, especially with the interactive die explorer near the bottom.
Don’t forget to check the notes at the end, especially the large-size 555 timer created by Evil Mad Scientist Lab.
