Dumber phone
Less is exponentially more – Rob Pike Smart phones are useful, but they are also incredibly addictive, and that addiction is at the epicenter of Silicon Valley’s effort to grab an ever-increasing percentage of our minds. If a substance or behavior controls us, it becomes our master, and that just won’t do. For the…

Mmm, Pi-hole
I have a love-hate relationship with ad blockers. On the one hand, I despise the obnoxious ads that are forced down our throats at what seems like every turn. On the other hand, I appreciate the need for publishers to earn a living so that I can consume their

Finding a CPU Design Bug in the Xbox 360
The recent reveal of Meltdown and Spectre reminded me of the time I found a related design bug in the Xbox 360 CPU – a newly added instruction whose mere existence was dangerous. Back in 2005 I was…

Why does a spray bottle work?
Exploring a simple machine I took apart a simple spray bottle to see how it kept fluid flowing only in one direction from the reservoir to the nozzle. It does so with simple check valves made of two pieces of plastic, a spring, and a small sphere. It’s a simple way to solve a tricky problem. A simple spray bottle One…

Every 7.8μs your computer’s memory has a hiccup
I was particularly interested in one of the consequences of how dynamic RAM works. You see, each bit of data is stored by the charge (or lack of it) on a tiny capacitor within the RAM chip. But these capacitors gradually lose their charge over time.

Serious Intel CPU bugs (2016)
2015 was a pretty good year for Intel. Their quarterly earnings reports exceeded expectations every quarter. They continue to be the only game in town for the serious server market, which continues to grow exponentially; from the earnings reports of the two largest cloud vendors, we can see that AWS and Azure grew by…

We're in a Golden Age for Amateur Radio
When I started my ham life as KK6VSI in August of 2015, I wish I could have had the information I'm about to lay out here. Of course, most of the equipment didn't yet exist. So another way of looking at it is that my entry into amateur radio was perfectly timed for my generation's Golden Age of Ham Radio.

Why Skylake CPUs Are Sometimes 50% Slower
I got a call that on newer hardware some performance regression tests have become slower. Not a big deal. Usually it is a bad configuration somewhere in Windows or some BIOS settings were set to no…

2018 Mac Mini Review
I hardly ever think about my Mac Mini, but it serves a vital role for my family as our home-theater mixer , Plex server, ScanSnap server, Apple Photos backup, and Backblaze host for our NAS . 1 Almost every port on the back is in use, and it runs 24/7, reliably, in total silence.
