Software: gksu Alternatives, bootiso and Yay

• Opening Graphical Application with Root Permission – gksu Alternatives in Ubuntu 18.04

  Recently, Ubuntu 18.04 removed gksu from its repositories, causing panic in anyone who relied on the utility on a regular basis. What many people didn’t realize, though, was gksu hadn’t been maintained in a long time. It was already a dead program. Ubuntu finally just made the move to cut ties with it.

• bootiso: Easy ISO To Bootable USB Drive From The Command Line

  If you're looking for a command line tool that is able to create a bootable USB drive from both hybrid and non-hybrid ISO images (it should work with any Linux distribution ISO as well as Microsoft Windows ISO files), with some safety checks in place, you may want to give Bootiso a try.

• Yay – Yet Another Reliable AUR Helper Written In Go

  Howdy Arch Users! I’ve got a good news for you. Today, I stumbled upon yet another reliable AUR helper called “Yay”. Yep! the name of this AUR helper is Yay. In the past, I was using Pacaur for installing AUR packages. It did a great job and I really liked it. I have also used some other AUR helpers such as Packer and Yaourt as well. But, they are all now discontinued and not recommended to use anymore. After reading about Yay features, I thought to give “Yay” a try and see how things works. So, here we go!

Security: Defective Processors, Malicious Proprietary Software and Cost of Bad Software

• freenode Launches New Job Board, Two More Spectre Security Holes Discovered, Debian Joins KDE's Advisory Board, Android Malware Found in the Google Play Store and Stable Kernels Released

  Two new Spectre-type security holes have been discovered. ZDNet reports that this affects any operating system running on AMD, ARM and Intel processors. Vladimir Kiriansky, PhD candidate at MIT, and independent researcher Carl Waldspurger found the new vulnerabilities and published a paper. ZDNet also notes that so far, no known attacks have occurred making use of these bugs, but that likely will change soon.

• Android security: Password-stealing malware sneaks in Google Play store in bogus apps

  A cyber crime group has sneaked apps onto the official Google Play Store which then serve up Trojan banking malware to Android users, security researchers have revealed. Uncovered in June, the campaign delivered Anubis malware designed to steal login credentials for banking apps, e-wallets and payment cards. The payload was hidden in applications which claimed to offer services ranging from online shopping to live stock-market monitoring.

• Google Chrome Will Start Using 10% More RAM Now, Thanks to Spectre

  Soon Google Chrome is going to use even more of your RAM, assuming that it’s even possible to use more than it already does. This is because of Chrome 67’s new Site Isolation feature to protect against Spectre.

• Security in Open Source Software Isn’t Automatic – but It Should Be [Ed: WhiteSource wants to sell its crap. Pretends only FOSS has bugs, as usual. Might as well say, "Security in Proprietary Software Isn’t Automatic"]

• It’s All In The Libs – Building A Plugin System Using Dynamic Loading

  Shared libraries are our best friends to extend the functionality of C programs without reinventing the wheel. They offer a collection of exported functions, variables, and other symbols that we can use inside our own program as if the content of the shared library was a direct part of our code. The usual way to use such libraries is to simply link against them at compile time, and let the linker resolve all external symbols and make sure everything is in place when creating our executable file. Whenever we then run our executable, the loader, a part of the operating system, will try to resolve again all the symbols, and load every required library into memory, along with our executable itself. But what if we didn’t want to add libraries at compile time, but instead load them ourselves as needed during runtime? Instead of a predefined dependency on a library, we could make its presence optional and adjust our program’s functionality accordingly. Well, we can do just that with the concept of dynamic loading. In this article, we will look into dynamic loading, how to use it, and what to do with it — including building our own plugin system. But first, we will have a closer look at shared libraries and create one ourselves. Note that some details may vary on different architectures, and all examples in here are focusing on x86_64 Linux, although the main principles should be identical on other systems, including Linux on ARM (Raspberry Pi) and other Unix-like systems.

Trisquel 8.0 LTS Review: Successful Freedom of 2018

Trisquel 8.0 is a success in reaching freedom goal (meaning: no proprietary at all) for overall computer users, especially desktop. It is a 100% free distro which is complete, user friendly, and instant. Compared to regular distros, it's at least equally low in requirements but high in usability; compared to common free distros, it's active (not dormant) and long-standing (since 2007). This operating system can be used by general computer users, produced in mass computers (i.e. sold in a PC/laptop), and especially software freedom people. This year, 2018, anybody wants the true free distro would be happy with Trisquel.
