You can’t throw out your worn-out USB security keys when you can’t recall what locks they’re for. Physical security tokens come with their own problems.

<p>Five years ago, I wrote about adopting security keys — small second-factor authentication token devices — to secure some of my most precious online accounts. In that article, I foresaw a future problem and detailed how I planned to mitigate it. The future is now, and I did not heed my own advice. 🤦‍♂️</p> <p><a href="https://www.ctrl.blog/entry/security-key-decommission.html">Read more …</a></p> urn:uuid:3c0ff38a-0d91-4ae4-bdbd-d48b2aeec85b 2022-09-20T09:32:00Z 2022-09-20T09:32:00Z

The Aqara temperature and relative humidity sensor for Zigbee-home automation is unreliable and it doesn’t work in humid environments (where you’d want one!)

<p>The Aqara Temperature and Humidity sensor by Xiaomi is a popular option to capture indoor climate data for home-automation systems. 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

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

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

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>
