Xfce 4.14 review - Holding out for a hero

Filed under
Reviews

People often ask me (joking, no one asks me anything, I ain't got no friends) what my favorite Linux desktop is. And my answer is, well, long and complicated. But I guess, in the past fifteen years, I've mostly used and loved Plasma and Unity, with some brief moments of joy with Gnome 2. Then, inevitably, the question of Xfce comes up, and my answer is even longer and more complicated.

The release of Xfce 4.14 might provide a part of the answer you're looking for. And you should definitely look at my reviews of various distros running Xfce, like say Xubuntu or MX Linux, to get a sense of what this desktop environment does, and how it does it. But then, it's never been really my default go-to setup, although I did use it quite successfully and effectively - and still do - on my feisty, 10-year-old Asus eeePC netbook. On the desktop proper, I like it, and I liked what it did approximately three years or so. Since, it's kind of kept a quiet profile, not quite here nor there. Well, I want to see if the new version has the kick to make my proverbial colt buck and gallop. Testing time it is then!

  • Valve just turned the gameplay of Dota Underlords on its head with Contraptions

    Valve seem to be using Early Access to really mix things up for Dota Underlords, with a new update out adding in Contraptions you can put on the board.

    While I like Underlords a lot, I was pretty keen to see them do a little more with it. So the idea of Contraptions is pretty fun and it does mix the gameplay up quite a bit. You can place them on the board, move them around and they will affect the combat making placement even more crucial than ever. They also don't count against the normal unit cap.

  • Wine Is Now In Better Shape On NetBSD Thanks To GSoC 2019

    In addition to NetBSD seeing better DRM ioctl support for its Linux compatibility layer (as part of an effort towards possible Steam support) thanks to Google Summer of Code 2019, there were also Wine improvements as a result of this Google programming initiative.

    Student developer Naveen Narayanan worked the summer on improving NetBSD's Wine support, particularly when it comes to AMD64 (x86_64) support.

Need A Good Linux Hex Editor? 20 Linux Hex Viewers & Editors Reviewed

Software

A hex editor is a computer program used for editing a binary file that contains machine-readable data. It paves the way of manipulating raw binary data for a particular application. “Hex” is the short form of hexadecimal, a numerical standard format that represents the binary program. A regular hex editor has three specific areas such as ‘character area’ on the right, ‘hexadecimal area’ in the middle and the ‘address area’ on the left. Additionally, some hex editors are designed to edit and parse sector data from the hard disk and floppy disk which are frequently called disk editor or sector editor. There are far ranges of Linux hex editor available in the market; that to a greater extent make a user squarely beneficial, and allow them to edit binary program.

Filed under
Ubuntu

The release of Ubuntu Linux 19.10 edges ever closer, with an expected Beta release landing on September 26 ahead of the planned October 17 launch. Here's a brief rundown of what to expect, and a few features that might make it worth the upgrade from versions 18.10 or 19.04.

As always Ubuntu 19.10 will introduce the usual minor interface and software tweaks, but there are some highlights I'm seriously looking forward to, such as flicker-free boot for Intel users, similar to what you see today in Fedora 30.

Linux driver patches hint at AMD Renoir to support LPDDR4X memory

Linux

Great news this weekend for APU fans out there – while the AMD Navi GPUs and Ryzen 3rd generation chips are currently taking over the computing world, it doesn’t mean that the company has forgotten about its integrated graphics users.

In a recent report by Tom’s Hardware, it looks like AMD’s next generation APU (Accelerated Processing Unit) might come with LPDDR4X-4266 memory support. If true, this means that AMD Renoir will have a higher maximum data rate than AMD Picasso.

Linux 5.4 Lands A Number Of Memory Management Fixes

While mid-way through the Linux 5.4 development cycle with RC4 due out on Sunday, a number of memory management fixes just hit the mainline kernel. Andrew Morton's pull request was merged on Friday night and he noted, "Rather a lot of fixes, almost all affecting mm/" Indeed there were memory management fixes in this pull ahead of 5.4-rc4. Changes include a zRAM race condition fix, avoiding access to uninitialized memory maps, allow dropping transparent huge-pages (THP) from the page cache, and other fixes in this area including the possibility of a kernel crash.

  • AMD Zen 2 Improvements For LLVM Have Been Held Up For Months By Code Review

    Back in February for LLVM Clang 9.0 was the initial AMD Zen 2 "znver2" enablement, but like the GCC support at the time it was the very basics. With time GCC picked up Zen 2 scheduler improvements and other work while sadly in the case of LLVM the improvements are still pending. Back in August, AMD's Ganesh Gopalasubramanian sent out the znver2 scheduler model for LLVM for Zen 2 CPUs but a focus on the EPYC 7002 "Rome" processors. "There are few improvements with respect to execution units, latencies and throughput when compared with znver1. The tests that were present for znver1 for llvm-mca tool were replicated. The latencies, execution units, timeline and throughput information are updated for znver2."

  • Python Add Lists

    This tutorial covers the following topic – Python Add lists. It describes various ways to join/concatenate/add lists in Python. For example – simply appending elements of one list to the tail of the other in a for loop, or using +/* operators, list comprehension, extend(), and itertools.chain() methods. Most of these techniques use built-in constructs in Python. However, the one, itertools.chain() is a method defined in the itertools module. You must also see which of these ways is more suitable in your scenario. After going through this post, you can evaluate their performance in case of large lists.

  • 3D using Godot

    It is time for another installment of Godot (previous entries: introduction, 2D). This time, I have dived into the world of 3D. The goal is to recreate parts of an old time favorite: Kosmonaut. Something I remember playing a lot on my dad’s 286 with amazing EGA graphics. The state of the game when writing can be seen in the short screen capture below. This is more of a tech demo status than a full game at the moment, but I hope you will still find it interesting. You can also get the complete source code. [...] Once we have a world with a track (the grid map), we add a player to the scene (the yellow blob in the image above – I need to learn Blender to create a proper ship). The player scene contains the ship – and the camera. This means that the camera follows the player automatically – very convenient. The player script is responsible for this ship’s movements based on user input. Inputs can either be pressed for a long time, used for sideways movement, or just tapped (i.e. the release is ignored), used for jumping. Each of the inputs are mapped to a keyboard key (or other input device) in the Project Settings dialog, under the Input Map tab. This feels a bit awkward to me and makes me lose the feeling of flow – but I don’t know how to do it better.

Xfce 4.16 development phase starting

In the 4.14 cycle we tried to do a 1:1 port of what used to be our Gtk2 desktop environment, avoiding visual changes. In the 4.16 cycle we plan to harmonize the appearance of certain elements that either became inconsistent through the port or already were inconsistent before (e.g. toolbars or inline toolbars). We will also play with client-side decorations where we feel it makes sense (for instance replacing the so-called XfceTitledDialog, that is used for all settings dialogs with a HeaderBar version). Before anyone gets too excited (both positively or negatively): It is not planned to redesign more complex applications (like Thunar) with Headerbars in 4.16. We will however try to keep the experience and looks consistent, which means gradually moving to client side decorations also with our applications (please note that client side decorations are not the same as HeaderBars!). Through this change e.g. “dark modes” in applications will look good (see the part about the Panel below). Now before there is a shitstorm about this change I would kindly ask everyone to give us time to figure out what exactly we want to change in this cycle. Also, switching to client-side decorations alone is not a big visual departure – feel free to also dig through the client-side decorations page if you want to read/see more on this. Read more
