• Try Jed as your Linux terminal text editor | Opensource.com

  You may have heard about Emacs and Vim and Nano, the quintessential Linux text editors, but Linux has an abundance of open source text editors, and it's my goal to spend December giving 31 of them a fair go. In this article, I look at Jed, a terminal-based editor featuring a handy drop-down menu, which makes it especially easy for users who are new to terminal editors, as well as those who just don't like remembering keyboard combinations for every function.

• PAPPL 1.0 RC1 Released With A Goal To Replace CUPS Printer Drivers - Phoronix [Ed: They would be wiser not to use GitHub]

  CUPS printing system founder Michael Sweet who left Apple last year and that left CUPS in a stagnate position (as of writing, still no commits to their Git repository since April) while Sweet continues pushing ahead with his new and modern "PAPPL" effort. PAPPL is the printer application framework being worked on by Michael Sweet over the past year for developing CUPS Printer Applications as a replacement to the conventional CUPS printer drivers. PAPPL supports JPEG / PNG / PWG Raster / Apple Raster / raw printing to printers via USB or network connections and supports an embedded IPP Everywhere service.

• Design of the CRLite Infrastructure

  Firefox is the only major browser that still evaluates every website it connects to whether the certificate used has been reported as revoked. Firefox users are notified of all connections involving untrustworthy certificates, regardless the popularity of the site. Inconveniently, checking certificate status sometimes slows down the connection to websites. Worse, the check reveals cleartext information about the website you’re visiting to network observers. We’re now testing a technology named CRLite which provides Firefox users with the confidence that the revocations in the Web PKI are enforced by the browser without this privacy compromise. This is a part of our goal to use encryption everywhere. (See also: Encrypted SNI and DNS-over-HTTPS)

Lenovo ThinkPad X1 Yoga: 6 month impressions

I’ve now had my Lenovo ThinkPad X1 Yoga laptop for about 6 months, so I thought I’d provide a quick update about how it’s going to use this laptop every day with openSUSE Tumbleweed running KDE Plasma. Let’s explore what’s changed since then... Initially, I complained about some aspects of the keyboard layout, but I’ve gotten used to the Home/End/PageUp/PageDown positioning, and the swapped position of the Fn and Ctrl keys. These are fine now. Lack of media keys is okay too since I’ve used the Shortcuts KCM to set my own. However I just can’t get used to the PrintScreen key being between the right Alt and Ctrl keys. I probably press it by accident 10 times a day and bring up Spectacle when I don’t mean to. One of these days I should get around to using xmodmap or something to turn it into a right Meta key, and they maybe make the F11 key which currently does nothing be the new PrintScreen key.
