Most websites and many apps loaded slowly, partially, or not at all. Just had to wait it out. <p>I don’t know what I did wrong, but I’ve angered one of the titans of the internet! For the last six days, my home internet connection has been partially broken. Some apps and many websites either load slowly, partially, or not at all. Everywhere I go, I’m greeted by the same blockade message from Cloudflare.</p> <p><a href="https://www.ctrl.blog/entry/cloudflare-ip-blockade.html#src=feed">Read more …</a></p> urn:uuid:3c0ff38a-0d91-4ae4-bdbd-d48b2aeec85b 2022-09-20T09:32:00Z 2022-09-20T09:32:00Z Review: Aqara indoor climate sensor (for home automation) 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 (available on Amazon) 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#src=feed">Read more …</a></p> urn:uuid:c4e5ee2d-3514-42bb-a27e-2760b2f37758 2022-09-04T14:01:00Z 2022-09-04T14:01:00Z TP-Link band-steers 2,4 to 5 GHz Wi-Fi even when the radio is off TP-Link Wi-Fi access points mindlessly band-steer clients off 2,4 GHz to the 5 GHz radio; even during periods when the 5 GHz radio is powered off. <p>My TP-Link EAP653 (available on Amazon) Wi-Fi access point (AP) has some features that don’t work well together.

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#src=feed">Read more …</a></p> urn:uuid:e37b8590-a8c5-4159-96a1-e50e89bb82f8 2022-08-12T16:16:00Z 2022-08-12T16:16:00Z Stop using DICT dictionary apps (such as GNOME/MATE Dictionary) MATE Desktop installs a Dictionary app (a fork of the retired GNOME Dictionary app).

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#src=feed">Read more …</a></p> urn:uuid:bc46ab39-9a74-4690-8896-eed28aac875b 2022-07-20T09:26:00Z 2022-07-23T19:06:00Z TeamViewer installs suspicious font only useful for web fingerprinting A weird almost unreadable font file bundled with TeamViewer for Windows software lets website detect if you’ve installed the software. Raises privacy concerns. <p>So, here’s a bit of a mystery: Why does TeamViewer – the popular remote desktop program – install a font it doesn’t use on your computer? The abstract font (shown in the above image) doesn’t seem to serve any purpose in the software. Intentional or not, it enables websites to detect if you have TeamViewer installed on your computer.</p> <p><a href="https://www.ctrl.blog/entry/teamviewer-font-privacy.html#src=feed">Read more …</a></p> urn:uuid:210a619d-598e-4152-a92c-2f942e163c47 2022-07-10T13:26:00Z 2022-07-10T13:26:00Z On-device browser translations with Firefox Translations Firefox can now do offline and privacy-preserving translation of eight languages with more on the way.

Set and forget on your favorite slow channels. <p>You can find hundreds of browser extensions that let you fine-tune the playback speed for all YouTube videos. I’m happy with the default speed of 1× for most videos (and music). However, I want to speed up some channels without having to tweak the speed dial every time.

Its unique hardware comes with unique software problems. <p>The Dygma Raise is a splittable 60 % mechanical keyboard; meaning it has no function key row, navigation keys, arrow keys, or numpad. It’s squarely targeted at keyboard enthusiasts willing to pay 350 USD for a keyboard with fewer standard keys plus a unique two-rowed eight-key space bar design.</p> <p><a href="https://www.ctrl.blog/entry/review-dygma-raise-split-keyboard.html#src=feed">Read more …</a></p> urn:uuid:ad15d106-70ed-465a-a4d6-708f28641574 2022-06-13T13:36:00Z 2022-06-13T13:36:00Z 7 simple bot detection methods that won’t inconvenience users Protect your contact, comment, or other forms from spam submissions by evaluating minute details about how it got submitted. Privacy-preserving. No CAPTCHAs. <p>Millions of (poorly coded) bots relentlessly crawl the web to detect and spew junk content into any form they find. The go-to countermeasure is to force everyone to complete a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA). CAPTCHAs are those annoying user-hostile tests where you type in skewed letters or identify objects in photos. They require cultural familiarity, introduce accessibility barriers, and waste everyone’s time. Instead of using a CAPTCHA, you can detect and block many bot submissions using completely unobtrusive form validation methods.</p> <p><a href="https://www.ctrl.blog/entry/detect-non-browser-form-submission.html#src=feed">Read more …</a></p>
