    Well, my Dad was someone who loved gadgets (he may have passed this on). Everything was carefully researched and I find myself gradually acquiring all those old components and pieces.

  • Apple Watch does not pair with AirPods

    Man, this was mighty frustrating. The pairing between Apple Watch and AirPod has been seamless for a long time, but just this week, I found that my Apple Watch kept saying, “can’t find AirPod Pros”. This happens even if I turn off every Bluetooth device that has ever paired with the AirPod. I even tried…

  • Now a diversion on Free Energy and the Brain

    In the world of Covid-19, it’s hard to think about anything else, but while doing some exercise, listening to Sean Carroll has been great. His book on Quantum Physics called Something Deeply Hidden was excellent. But this latest podcast with Karl Friston was something else. Who knows if it is correct, but there are two…

  • Life in Wartime: Training at Home

    Well, it doesn’t look like we are getting to the gym anytime soon and the thought of running or biking around when this virus is everywhere doesn’t seem smart. So it looks like it’s finally time to set up a decent home gym that has the minimum of stuff that I need: We have some…

  • Making Your PC A Work of Art

    I’ve been chatting with Tim and Brian quite a bit about how PCs are changing from productivity machines to (particularly for gamers) works of art that should be displayed. Just looking at our latest Threadripper miniTower build shows how easy it is to get the right hardware: NZXT H510. It is easy to get a…

  • Right ratios of Rectangles

    When you are building a presentation, how should you lay things out and what are the right ratios. The main thing to realize is that if your slide is 16:9, then it makes some sense to have rectangles that are longer than they are tall. The Golden Ratio. This is buried deep in the mathematical…

  • Life in wartime: company survival rules

  • Word to the wise when building PC, buy with Amex Platinum if you can

    Since I’ve been building PC, I’ve completely forgot that you can get infant mortality problems where things die early. We just had a $550 motherboard literally die after one week of use. ASUS is awesome because they have online chat to get through this, but here are some things to know: When you are buying…

  • Video Conferencing with Zoom and Keeping your Internet Speed Great

    Well now that so many of us are at home, figuring out how to keep your video and other calls running well is more important than ever. Since yesterday, our network speeds have been horrible.

  • More Self-Quarantine Options DoorDash, and Drizly

    OK, with self-quarantine the new meme, here are some notes about how to minimize contact: In Singapore, when you go out, you leave your shoes at the door, change out and wash your “outside” clothes and switch to indoor clothes.

  • Great coding practices from a genius

    Well the smartest person I know (ok I’m biased one of the three smartest people amongst the Alex, Calvin and Grace crowd).

  • Argh when your Windows machine dies

    I haven’t used Windows much these last few years. Most development has been on the Mac and Linux. But getting back to it because of gaming and I had completely forgotten how delicate Windows can be. We have a Dell Alienware Aurora R8 computer and it tries to work like a sealed box. I got…

  • Multiple nVidia Cards

    Well in the old days, there was a thing called SLI which basically had two video cards and they each took a line of a display, so you could get them to really cooperate.

  • When you Kodi breaks on an Nvidia Shield

    Kodi (formerly XBMC, formerly Xbox Media Connect) has been an awesome tool for us to have a nice front end so that handles all the DVDs and other things we have digitally in the house.

  • Beware when buying from Corsair.com of 22 day hold

    ARgh, yet another fall out of the Corona Virus that they don’t talk about much, but if you are buying from Amazon, getting things from China doesn’t seem to be a problem.

  • Data Integrity at Home : Data Scrubbing and Hashdeep

    OK, when you have terabytes of data at home, you definitely will. have losses. I’ve had a bad RAID array that corrupted a bunch of JPEGs and it is super sad. So what’s the solution to this: If you are using BTRFS, then you can turn on bit scrubbing. This basically in the background ensures…
