  • Notepadqq is a best alternative to Notepad++ for Ubuntu/Linux Mint

    Do you miss Notepadd++ which is only available for Microsoft Windows? Here is an alternative for you called "Notepadqq" released under GPL (GNU General Public License) Version 3. Notepadqq is a Notepad++-like editor for the Linux desktop. It helps developers by providing all you can expect from a general purpose text editor, such as syntax highlighting for more than 100 different languages, code folding, color schemes, file monitoring, multiple selection and much more. You can search text using the power of regular expressions. You can organize documents side by side. You can use real-time highlighting to find near identifiers in no time. It has support for multiple programming languages, multiple encodings and plugin support.

  • My experience with WikiToLearn

    When I first started with Google Code In, I thought that it would be about work that is done fast and easy. With that attitude I had to abandon my first task at a random company (I don't remember). Seeing that this contest is pretty advanced, I looked for a task that fit to my programming skills which brought me to WikiToLearn: My first task was to run W2L locally so I can edit a part of the website.

  • The Sysadmin Squad

    Spectacle is out as part of the Applications suite as of KDE Applications 15.12, and not only do the users like it, other devs love it too. Maintaining Spectacle isn't as hectic as it used to be in the early days. I get a steady stream of mostly benign bug reports, which is nothing I can't handle in a few hours over the weekend. Wayland support still hasn't materialised though, and it looks like it'll be a while. Proper High-DPI (retina displays) support did materialise though, courtesy of Kai Uwe Broulik, and will land in 15.12.1.

  • Calculate Linux 15.12 Released With Various Changes, Now Supports AMDGPU

    The developers working on Calculate Linux decided to release a new version of their Gentoo-based Linux operating system before heading to New Year parties.

  • Manjaro 15.12 Capella Received Its First Update

    The first Manjaro 15.12 Capella update has been released by the developers, bringing interesting changes, including updated Plasma5 to version 5.5.2, dbus 1.10.6, thunderbird 38.5, Kernel 4.4 RC7, Mesa 11.1.0, fixes for the Maia GTK theme, updated python and haskell packages, an updated version of wine, new deepin settings and the brand new Budgie 10.1 desktop environment.

  • Ubuntu Touch OTA-9 Will Bring A New Download Manager

    The Ubuntu developers are currently working at a download manager to add by default on Ubuntu Touch, starting with the OTA-9 Update. The software would permit the users to download files directly from the browser, without having to send them to other apps, or download a file once and send it to multiple apps without needing to redownload each time.

  • fail0verflow Gets Linux Running on PlayStation 4

    Can it run Linux? Yes, we're just as tired of the Web joke as anyone else, but it is a fair question for some devices—especially gaming consoles, which are basically just computers in a different form factor than what you're used to seeing under (or on top of) your office desk.

    The PlayStation 4 has been fairly resilient to various forms of modding, as it was only really "jailbroken" earlier this month. This process allows those with modified consoles to run, well, just about whatever they want on them, from pirated games to custom software.

Vivaldi 5.0 Brings Early Christmas Gift - Introduces Shareable Browser Themes, Automatic Translation

Vivaldi 5.0 released with impressive updates and arguably making it the best Linux web browser today. Read on for the release coverage. Read more

Vivaldi Web Browser Turns 5, Celebrates with New Features

Thankfully I didn’t need to think too hard. The brains behind the browser made a unique play from the off, positioning Vivaldi as the choice du jour for power-users left frustrated by the tightly-controlled experiences offered elsewhere. To celebrate its fifth birthday the browser makes a new update available, Vivaldi 5.0. Vivaldi 5.0 includes a couple of interesting additions (which I’ll get to in a moment) but the real party is taking place over on Android. Vivaldi for Android 5.0 introduces something of a first: a two-tier tab bar (!). Read more

today's howtos

  1. My Homelab NAS on NixOS

    Installing NixOS was utterly painless. Using a combination of settings from the Arch Linux wiki (seriously wish I could get a printed copy of that thing, it's worth its weight in gold for how much weird arcane things you can learn from it), the NixOS wiki and copying things off of a Synology box's samba configuration file, I managed to trick everything into working and now all the machines on our tailnet can access the data on the NAS without too much trouble. Even iPhones and iPads thanks to the recent addition of SMB mounting on iP{hone|ad}OS. It also works over Tailscale too, so I can get into the NAS' files anywhere I have an internet connection.

  2. Logitech MX Keys and MX Master on OpenBSD using Logi Bolt

    Long story short, I need a way to manage a Windows (pro) laptop, an OpenBSD thinkpad and an iPad Pro with a single keyboard & mouse. After a bit of digging, I ended up getting a Logitech MX Keys and Logitech MX Master 3.

  3. SSH alternatives for mobile, high-latency or unreliable connections

    SSH is the best option in most cases. It is widely used, usually installed by default, and clients exist for every platform. However, there are a few cases where you may want to consider an SSH alternative. I was recently looking for ways to solve these edge cases. These are my notes on alternative SSH servers.

  4. Unfortunately, damaged ZFS filesystems can be more or less unrepairable

    The second unfortunate aspect is that generally you can't repair this damage the way you can in more conventional filesystems. Because of ZFS's immutability and checksums, once something makes it to disk with a valid checksum, it's forever. If what made it to disk was broken or corrupted, it stays broken or corrupted; there's no way to fix it in place and no mechanism in ZFS to quietly fix it in a new version. Instead, the only way to get rid of the problem is to delete the corrupted data in some way, generally after copying out as much of the rest of your data as you can (and need to). If you're lucky, you can delete the affected file; if you're somewhat unfortunate, you're going to have to destroy the filesystem; if you're really unlucky, the entire pool needs to be recreated.

    Windows 11 is the latest Microsoft operating system that we can install on Ubuntu 20.04 focal fossa Linux to test it using VirtualBox. Here we let you know how? If you have just moved to Linux for some reason but there are some apps that only work on Windows such as Microsoft Office, Adobe, and others. Then running Windows using a Virtual machine is a good idea. For those who don’t know about VirtualBox, it is an open-source application to create and manage virtual machines on all popular operating systems.

Kernel Space: Rollercoaster, Memory Management, Linux 5.16, and More

  • Rollercoaster: group messaging for mix networks [LWN.net]

    Even encrypted data sent on the internet leaves some footprints—metadata about where packets originate, where they are bound, and when they are sent. Mix networks are meant to hide that metadata by routing packets through various intermediate nodes to try to thwart the traffic analysis used by nation-state-level adversaries to identify "opponents" of various kinds. Tor is perhaps the best-known mix network, but there are others that make different tradeoffs to increase the security of their users. Rollercoaster is a recently announced mechanism that extends the functionality of mix networks in order to more efficiently communicate among groups. Tor uses multiple relay nodes, each of which only knows its predecessor and the node to pass the message on to. It relies on the difficulty of tracking messages through that path, but a sophisticated and well-placed adversary can do various kinds of traffic analysis to potentially match up traffic between two endpoints, thus drawing conclusions about the participants in the communication. To minimize latency, Tor nodes forward packets as quickly as they can, which may help eavesdroppers correlate the traffic. The Rollercoaster developers, Daniel Hugenroth, Martin Kleppmann, and Alastair R. Beresford from the University of Cambridge, used the Loopix mix network to validate their work. Loopix is different from Tor in that sacrifices latency in order to make traffic analysis even more difficult. The client endpoints in such a mix network send fixed-sized packets at a fixed rate; if there is no outbound traffic, a cover packet is sent that is indistinguishable from normal traffic. The packets are sent to the relay nodes, which independently delay each packet before passing it on to the next relay. All of that makes it much more difficult to correlate the traffic and identify communicating endpoints.

  • Some upcoming memory-management patches [LWN.net]

    The memory-management subsystem remains one of the most complex parts of the kernel, with an ongoing reliance on various heuristics for performance. It is thus not surprising that developers continue to try to improve its functionality. A number of memory-management patches are currently in circulation; read on for a look at the freeing of page-table pages, kvmalloc() flags, memory clearing, and NUMA "home nodes".

  • 5.16 Merge window, part 2 [LWN.net]

    Linus Torvalds released 5.16-rc1 and ended the 5.16 merge window on November 14, as expected. At that point, 12,321 non-merge changesets had been pulled into the mainline; about 5,500 since our summary of the first half of the merge window was written. As is usually the case, the patch mix in the latter part of the merge window tended more toward fixes, but there were a number other changes as well.

  • Intel SGX2 / Enclave Dynamic Memory Management Patches Posted For Linux - Phoronix

    While Intel's Software Guard Extensions (SGX) functionality has been present in CPUs going back to Skylake, it took until last year with Linux 5.11 for SGX support to finally be mainlined and required more than 40 rounds of review/revisions. Finally today Intel posted patches for bringing up SGX2 as the next iteration of Software Guard Extensions and already found in shipping processors. Intel SGX is about defining private memory regions "enclaves" that are encrypted and cannot be read/used by any other processes or the host. SGX can be used for some interesting secure computing scenarios but the belated kernel support as well as various possible security vulnerabilities / attacks have rather limited its scope so far. Earlier this year building off the prior SGX support in Linux 5.11, SGX was brought for KVM guest support in v5.13.
