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> urn:uuid:c8a7dafd-113c-4d69-924c-66f0f2d86a46 2022-06-12T22:00:00Z 2022-06-12T22:00:00Z The Current Version of Popular Browsers API (powered by Wikidata) Need an API to get the current version numbers for the stable and extended support releases of Firefox, Google Chrome, and Safari? Wikidata got your back. <p>What’s the current stable version of Google Chrome, Firefox, and Safari? Your browser automatically checks for and keeps itself up to date.

Free and premium options. <p>It can be annoying to have to constantly remount network drives and network shares. Some apps can fail to launch if they depend on files stored on an unmounted network share.

Just raise the rack slightly off the floor and it becomes a natural robot barrier. <p>My robotic vacuum loves to ram itself onto and get stuck on my laundry drying rack.

However, the split key layout might also imposes accessibility issue for some. <p>Split keyboards can offer greater flexibility and variety for your working posture and desktop arrangements. I’m talking about both wave keyboards that bend upward in the middle (typically branded as “ergonomic keyboards”) and keyboards that can literally split in two.

The (font-)size-adjust property can set the minuscule (“lowercase”) size independently. <p>There’s more to setting the text size on your webpages than just the CSS <code>font-size</code> property. It only controls the size of majuscule (“uppercase”, e.g. “A”) letters, numbers, and punctuation. The size of minuscule (“lowercase”, e.g. “a”) letters is left up to the font. A font’s minuscule size metric is referred to as x-height; the height of an “x” letter. However, you can control the size of the two independently — and here’s why you might want to do that.</p> <p><a href="https://www.ctrl.blog/entry/font-size-adjust.html#src=feed">Read more …</a></p> urn:uuid:55d51586-281a-47b7-a134-977e8eed78d2 2022-05-05T20:46:00Z 2022-05-05T20:46:00Z Syncthing: The data deduplication master Syncthing can deduplicate data before network transfers and even utilize on-disk storage deduplication on modern file systems on Linux, Solaris, and Windows. <p>Syncthing is an open-source encrypted peer-to-peer folder synchronization program. It uses deduplication techniques to reduce the amount of data it needs to transfer over the network; saving you bandwidth costs, energy, and time.

However, the implementations vary a lot with different trade-offs. <p>I recently compared GEedit’s auto-save to Kate’s swap-save feature.

BIMI enables businesses to get their logos displayed next to their email messages in compatible email apps and webapps. As part of the research for that article, I queried the top 3 million domains to see how many had adopted the standard.

Among the changes was a big update to Psych version 4.0, Ruby’s built-in YAML Ain’t a Markup Language (YAML, a recursive acronym) interpreter.

Lately, I’ve concluded that every implementation with difficult-to-configure policies is just unmanageable. <p>Security-Enhanced Linux (SELinux) is a type of Mandatory Access Control (MAC) in the Linux kernel. It can prevent software from performing unexpected — such as abusive or malicious actions — on your Linux systems. However, … it’s also an unmanageable mess, and I have a much greater understanding of why people recommend that people disable it.</p> <p><a href="https://www.ctrl.blog/entry/selinux-unmanageable.html#src=feed">Read more …</a></p> urn:uuid:6d2db395-cd46-491d-b124-c017aea05af5 2022-04-25T20:19:00Z 2022-04-25T20:19:00Z Can you use a WebP file as an Open Graph Protocol image? Do you still need to maintain webpage thumbnails/link previews in legacy image formats, or have apps caught up with the WebP revolution? It’s a bit complicated. <p>The Open Graph Protocol (OGP) was created by and for Facebook in 2010. OGP is a pseudo-standard set of metadata tags you can include on your webpages to describe its contents. By now, it’s become the primary data source for generated link previews across the web and apps.</p> <p><a href="https://www.ctrl.blog/entry/webp-ogp.html#src=feed">Read more …</a></p> urn:uuid:7acb0143-2d17-486f-be45-728e9a6f42f2 2022-04-22T01:47:00Z 2022-04-22T01:47:00Z Get your logo into inboxes with BIMI and email best practices The new BIMI email standard give companies a branding opportunity in your email inbox in exchange for adopting stricter email sender-verification standards. <p>The new Brand Indicators for Message Identification (BIMI) internet standards <em>draft</em> lets businesses display their logos next to their emails (as the sender/contact photo).
