The sensors are small, plainly designed, cheap, promise 2-year battery life, and run on the Zigbee mesh-network protocol. However, they’re also notoriously unreliable, which defeats the desired set-it-and-forget-it target for the sensor.</p> <p><a href="https://www.ctrl.blog/entry/review-aqara-indoor-climate-sensor.html">Read more …</a></p> urn:uuid:9b1da4ae-7a06-499c-b967-08baf06e6872 2022-08-20T12:48:00Z 2022-08-20T12:48:00Z Finally fixed my PC’s persistent graphics and audio stutters I experienced intermittent stuttering when my PC ran Linux and Windows. A mix of hardware, firmware, and driver issues created a difficult to diagnose problem. <p>I’ve set up my gaming computer with dual booting between Fedora Linux and Windows 11. The Windows 11 installation doesn’t see much use these days since PlanetSide 2 became available on Linux. For the last two months, the system has suffered from stuttering issues during regular use and gaming. The display stops painting or gets partially corrupted, audio goes silent, and all operations halt for 0,5–2 seconds. Sometimes, the system even crashes, but it usually recovers by itself.</p> <p><a href="https://www.ctrl.blog/entry/troubleshoot-stuttering.html">Read more …</a></p> urn:uuid:fd01bf1b-cc6d-47bb-9045-f2015a5e5f4d 2022-08-02T07:25:00Z 2022-08-02T07:25:00Z “Gigabit Router” doesn’t mean it can deliver gigabit internet speed Make sure you buy a network router that can fully exploit your gigabit internet connection. Many routers say gigabit on the box, but doesn’t deliver gigabit speed. <p>Most manufacturers of consumer-grade network routers (both Ethernet and Wi-Fi) brand their products as “Gigabit Routers”. At the very least, it’ll say “Gigabit Ethernet”. However, neither term necessarily means the router can fully exploit your gigabit internet connection.</p> <p><a href="https://www.ctrl.blog/entry/gigabit-router.html">Read more …</a></p> urn:uuid:d8b2be17-7b4a-4c95-b88a-a87856aa08e8 2022-03-17T07:29:00Z 2022-03-17T07:29:00Z FreeStyle Libre 3 miniaturizes real-time glucose monitoring The new FreeStyle Libre 3 sensor is a true real-time glucose monitoring system and the market’s smallest CGM at a 70 % size-reduction compared to the old model. <p>I’ve worn the FreeStyle Libre 2 flash-glucose monitor (FGM) on my upper arm for the last three years. As a diabetic, I need to pay close attention to my glucose levels, and the Libre 2 was a revolution compared to finger-prick blood tests every couple of hours. The new Libre 3 system is a highly-anticipated update that massively improves on the Libre 2.</p> <p><a href="https://www.ctrl.blog/entry/freestyle-libre3-cgm.html">Read more …</a></p> urn:uuid:a1d60c41-8d4c-41c2-8a8c-bb56d7d0547c 2021-11-22T13:35:00Z 2021-11-22T13:35:00Z Why you need a HTPC A home theater/media center (HTPC) can enhance your experience. You get more reliable playback and better loudness normalization than a smart TV or Chromecast. <p>I haven’t watched linear TV for years. I usually know what I want to watch and the times I want to watch it. In other words, I’m a cable-cutter or an <em>on-demand streamer</em> as I prefer to think of it.</p> <p><a href="https://www.ctrl.blog/entry/why-htpc-benefits.html">Read more …</a></p>
