Apple puts modem engineering unit into chip...
by Thom Holwerda on February 9, 2019 at 1:43 am
Apple has moved its modem chip engineering effort into its in-house hardware technology group from its supply chain unit, two people familiar with the move told Reuters, a sign the tech company is looking to develop a key component of its iPhones after years of buying it from outside suppliers. Understandable move by Apple, both from a business perspective, and from a security perspective. The open source world really needs to build open source baseband processors at some point. […]
Building a RISC-V PC
by Thom Holwerda on February 9, 2019 at 1:22 am
While it’s clear that the most significant opportunities for RISC-V will be in democratising custom silicon for accelerating specific tasks and enabling new applications — and it’s already driving a renaissance in novel computer architectures, for e.g. IoT and edge processing — one question that people cannot help but ask is, so when can I have a RISC-V PC? The answer to which is, right now. The result is a RISC-V powered system that can be used as a desktop computer […]
A touchpad is not a mouse, or at least not a good...
by Thom Holwerda on February 9, 2019 at 1:12 am
One of the things about having a pretty nice work laptop with a screen that’s large enough to have more than one real window at once is that I actually use it, and I use it with multiple windows, and that means that I need to use the mouse. I like computer mice in general so I don’t object to this, but like most modern laptops my Dell XPS 13 doesn’t have a mouse, it has a trackpad (or touchpad, take your pick). You can use a modern touchpad as a mouse, but over my time in […]
PC speaker to eleven
by Thom Holwerda on February 8, 2019 at 1:03 am
«System Beeps» is a music album in shape of an MS-DOS program that features original music composed for PC Speaker using the same basic old techniques like ones found in classic PC games. It follows the usual retrocomputing demoscene formula — take something rusty and obsolete, and push it to eleven — and attempts to reveal the long hidden potential of this humble little sound device. You can hear it in action and form an opinion on how successful this attempt was at […]
What happened to the 100,000-hour LED bulbs?
by Thom Holwerda on February 8, 2019 at 12:59 am
Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I found was 25,000 hours. Others claimed only 7,500 or 15,000 hours. And yes, these are brand-name bulbs from Cree and GE. So, what happened to those 100,000 hour residential LED bulbs? Were the initial estimates just over-optimistic? Was it all marketing hype? Or, did we not know enough about LED […]
