Ubuntu Touch OTA-11 Now Available for Testing with Improved, Smarter Keyboard

Sre, 10/09/2019 - 20:28

Originally planned as a small update that was supposed to contain only some bug fixes and improvements, the Ubuntu Touch OTA-11 release appears to bring quite some enhancements for Ubuntu Phones, such as a much-improved and smarter keyboard that introduces a Dvorak keyboard layout option, improvements to the Japanese and Polish layouts, as well as a new way to edit text.

"Using this feature, you can move around your typed text, undo and redo actions, move around a text selection rectangle, and use the cut/copy/paste commands, all from the same overlay. To get started, press and hold the space bar," explained UBports. "We are still unsure about the discoverability of this feature, so stay tuned for changes that will make it even easier to find and use."

Celluloid is a really good mpv frontend for Linux

Sre, 10/09/2019 - 19:33

If you are a Linux user who wants a front-end for the popular MPV video player, Celluloid may be your best bet.

I installed the application via flatpak but you can find quite a few packages linked at the official GitHub; installation instructions for flatpak are available on the same page.

Celluloid mpv frontend for Linux

The GUI of Celluloid is quite similar to most Linux apps, and quite minimal. Click on the + button in the top left corner to open a video, or drag and drop one on to the interface. You can also load a web URL to stream content directly using the player from the Open Location menu.

Beware open source vendor lock-in

Sre, 10/09/2019 - 19:11

With open source having become not only mainstream but also so ubiquitous it is all but invisible, there is a real danger that open source users could find themselves in a whole new world of “open source” vendor lock-in.

That was the warning sounded by Obsidian’s Karl Fisher at the start of LinuxConf [ZA] 2019, a Linux and open source conference which marked the start of Open Source Week in South Africa this week.

Fisher took the delegates, mainly open source aficionados and developers, though a potted evolutionary history of open source – from the days when it was disparaged by Microsoft founder Bill Gates, and later his successor as CEO Steve Ballmer who infamously dubbed Linux a 'cancer'; to Microsoft’s recent, multi-billion dollar acquisition of GitHub, the world’s largest open source code hosting platform.

The Mitigation Impact Difference On AMD Ryzen 9 3900X vs. Intel Core i9 9900K Performance

Sre, 10/09/2019 - 17:26

Last week I shared benchmark results of the AMD Ryzen 9 3900X vs. Intel Core i9 9900K in 400+ benchmarks in the largest comparison ever for these two competing ~$500 USD processors. If that wasn't enough, I repeated the hundreds of CPU/system benchmarks again but without any of the recent CPU security mitigations in place to see how the situation would have played out pre-2018.

Immediately following those tests last week, I restarted the large benchmark queue with the 300+ system/CPU tests (foregoing the gaming benchmarks with the various CPU speculative execution vulnerabilities having little impact on gaming/graphics performance). As a reminder, both the Intel and AMD systems were tested on Ubuntu 19.10 with the Linux 5.3 kernel and all of the other latest software components for this H2'2019 update to Ubuntu Linux.

The Core i9 9900K was running with the ASUS PRIME Z390-A motherboard and the Ryzen 9 3900X with the ROG CROSHAIR VIII HERO WiFi motherboard, both boards using their very latest public BIOS releases as of testing. Both systems were tested with the same GSKILL 2 x 8GB DDR4-3600 memory, 280GB Intel Optane 900p NVMe SSD, and Radeon RX Vega 64 graphics card.

TeXstudio - A cushty yet nerdy LaTeX frontend

Sre, 10/09/2019 - 17:16

TeXstudio is a complex, powerful program, and it definitely appeals to my sense of nerdonics. It's rich in features, and it can take a while before you figure everything out - prior knowledge with similar software definitely helps. But then, I think LyX is friendlier and simpler, especially for beginners. With TeXstudio, there were a few errors throughout my test, which ought to be handled a bit more gracefully. Beamer sounds like a great thing, but then, frankly, most people will make do with Powerpoint, for better or worse.

I definitely intend to spend more time learning TeXstudio, as it may come handy in technical work now and then. Plus, there's the simple joy of mastering difficult tools, which then magically turn repetitive burdens into simple tasks. It's all about the optimization of energy. I believe I'm already there with conventional tools as well as LyX, so this ought to be an interesting experiment. For document lovers among you, this software definitely warrants some extended testing. We're done.

OSS: LibreOffice et al, OpenBSD crossed 400,000 commits, CMS news and Collapse OS

Sre, 10/09/2019 - 17:04
  • 8 tech freebies: Firewall, cloud storage, Office software and more

    LibreOffice is a set of open source software that’s equivalent to Microsoft Office. It lets you save and open documents in Microsoft formats and do everything Microsoft Office lets you do, like type in documents, set up spreadsheets and create presentations.

    If you’d like access to Microsoft Office, you can get the free trial of Office 365 for a month or you can try Office Online, a cloud-based version of the Microsoft Office Suite available to those with Microsoft accounts. Whichever software you get, you’ll have some amazing office capabilities without paying any money at all.

  • OpenBSD crossed 400,000 commits

    Sometime in the last week OpenBSD crossed 400,000 commits (*) upon all our repositories since starting at 1995/10/18 08:37:01 Canada/Mountain. That's a lot of commits by a lot of amazing people.

  • Steve Kemp: A blog overhaul

    All in all the solution was flexible and it wasn't too slow because finding posts via the SQLite database was pretty good.

    Anyway I've come to realize that freedom and architecture was overkill. I don't need to do fancy presentation, I don't need a loosely-coupled set of plugins.

    So now I have a simpler solution which uses my existing template, uses my existing posts - with only a few cleanups - and generates the site from scratch, including all the comments, in less than 2 seconds.

    After running make clean a complete rebuild via make upload (which deploys the generated site to the remote host via rsync) takes 6 seconds.

  • WordPress 5.3 Beta 3

    WordPress 5.3 Beta 3 is now available!

    This software is still in development, so we don’t recommend you run it on a production site. Consider setting up a test site to play with the new version.

  • Introducing Collapse OS, a z80 kernel that can be designed with “scavenged parts and program microcontrollers”

    There is a new operating system in the market which is designed in anticipation of the collapse of the current economic system – Collapse OS. The goal of this project is “to be as self-contained as possible.” With a copy of this project, its developer Virgil Dupras says, a capable person will be able to easily build and install Collapse OS without external resources. It will also be possible to build a machine with an exclusive design, and from discarded parts with low-tech tools.

    Dupras believes that the global supply chain will collapse before 2030 and post-collapse, it would be difficult to reproduce most of the electronics due to lack of supply chain. This will make it impossible to bootstrap the new electronic technology and thus limit its growth. At this point, Dupras says, Collapse OS can prove to be a good “starter kit”. He affirms that this operating system can be designed from “scavenged parts and program microcontrollers” with sufficient RAM and storage.

Critical Security Issue identified in iTerm2 as part of Mozilla Open Source Audit

Sre, 10/09/2019 - 16:55

A security audit funded by the Mozilla Open Source Support Program (MOSS) has discovered a critical security vulnerability in the widely used macOS terminal emulator iTerm2. After finding the vulnerability, Mozilla, Radically Open Security (ROS, the firm that conducted the audit), and iTerm2’s developer George Nachman worked closely together to develop and release a patch to ensure users were no longer subject to this security threat. All users of iTerm2 should update immediately to the latest version (3.3.6) which has been published concurrent with this blog post.

Founded in 2015, MOSS broadens access, increases security, and empowers users by providing catalytic support to open source technologists. Track III of MOSS — created in the wake of the 2014 Heartbleed vulnerability — supports security audits for widely used open source technologies like iTerm2. Mozilla is an open source company, and the funding MOSS provides is one of the key ways that we continue to ensure the open source ecosystem is healthy and secure.

iTerm2 is one of the most popular terminal emulators in the world, and frequently used by developers. MOSS selected iTerm2 for a security audit because it processes untrusted data and it is widely used, including by high-risk targets (like developers and system administrators).

What are Linux containers?

Sre, 10/09/2019 - 16:40

Programs used to be made by creating large monolithic scripts, however, a lot has changed in the last two decades. There are now prominent methods in manufacturing applications that use small, self-contained programs in tandem to add extra functionality to hardware.
Linux containers (LXC) are an operating system (OS) level virtualization method that allows for multiple isolated Linux systems to run on the single Linux kernel of a control host. Meaning that these programs are isolated in individual user-spaces and operate at the OS level. These containers are self-contained and lightweight, holding very few components, making them a powerful tool for adding applications to a system without worrying about dependency errors.

Developers can use containers to package an application with the libraries, dependencies and other files it needs to run, without the host needing to install extra assets. In this way, containers can be installed and work on any Linux system that supports container functionality regardless of configuration

The BlueMail Email Client is Now Available for Linux

Sre, 10/09/2019 - 16:23

The app boasts support for IMAP, Exchange & POP3 as well as all the leading web-mail providers and private mail server configurations.

“With this expansion to Linux, BlueMail is now able to serve a large professional market. Users can benefit from a single, modern user experience across all of their devices without compromising on premium features, security, or privacy,” Blix Inc, makers of BlueMail say.

Until today I had never heard of this app or service — but I’m probably alone because the BlueMail Android app has over 5,000,000 installs (yes, 5 million), and there are iOS and Windows versions available too.

“We set out to make the best email experience from day one and the response from customers has been extremely positive. Developing a platform for Linux was the next step,” Dan Volach, co-founder at Blix, adds.

Advanced Encryption Options Land in the YaST Partitioner

Sre, 10/09/2019 - 16:20

As you may know, so far the YaST Partitioner offered an “Encrypt Device” checkbox when creating or editing a block device. If such box is marked, the Partitioner asks for an encryption password and creates a LUKS virtual device on top of the device being encrypted.

LUKS (Linux Unified Key Setup) is the standard for Linux hard disk encryption. By providing a standard on-disk-format, it facilitates compatibility among distributions. LUKS stores all necessary setup information in the partition header, enabling to transport or migrate data seamlessly. So far, there are two format specifications for such header: LUKS1 and LUKS2. YaST uses LUKS1 because is established, solid and well-known, being fully compatible with the (open)SUSE installation process and perfectly supported by all the system tools and by most bootloaders, like Grub2.

You should not fix what is not broken. Thus, in most cases, the screen for encrypting a device has not changed at all and it still works exactly in the same way under the hood.

Ubuntu 19.10 Makes It So Easy To Have Your Desktop Running Off A ZFS File-System

Sre, 10/09/2019 - 16:16

As we reported this weekend, the Ubuntu desktop installer "Ubiquity" has landed the much anticipated ZFS install support. That's now propagated through to the Ubuntu 19.10 daily ISOs and does indeed make for a quick and easy setup of Ubuntu Eoan running off a root ZFS file-system.

This work landed just a week ahead of next week's official Ubuntu 19.10 debut. For Ubuntu 19.10 the Ubiquity installer allows an "experimental" option of doing a full-disk install of Ubuntu 19.10 with ZFS as the root file-system rather than the default EXT4. For the Ubuntu 20.04 LTS cycle they are expected to work on exposing more of the advanced partitioning features with ZFS. Also, Canonical developers are still working on their Zsys bits and other ZFS On Linux integration improvements.
