  • How to Install PyCharm on Debian 11 Bullseye

    PyCharm is a dedicated Python graphical IDE (Integrated Development Environment) popular amongst Python developers with its wide range of essential tools such as analyzing code, debugging, and integration. The IDE also comes with the command line, connects to a database, creates a virtual environment, and manages your version control system (Git).

    In the following tutorial, you will learn how to install PyCharm Community, Professional or Educational, with Flatpak or Snapcraft (Snap) on Debian 11 Bullseye.

  • Install apps on Linux with Flatpak | Opensource.com

    Computer applications consist of many small files that are linked together to perform a set of tasks. Because they get presented as "apps," colorful icons in the menu or on a desktop, most of us think of applications as a single, almost tangible thing. And in a way, it's comforting to think of them that way because they feel manageable that way. If an application is actually the amalgamation of hundreds of little library and asset files scattered throughout your computer, where's the application? And existential crisis aside, what happens when one application needs one version of a library while another application demands a different version?

  • See, Multi-Account Containers extension is not needed to use Containers in Firefox – LinuxBSDos.com

    That last bit about integration with Mozilla VPN is new and can be useful in some edge situations. But we won’t get into that in this article. Let’s just focus on Containers. Like I said earlier, I’ve always relied on the Firefox Multi-Account Containers extension because I thought that was the easiest method of managing Firefox containers. But what I didn’t know is that the features that the Firefox Multi-Account Containers bring to the table are already built into Firefox Core, so all that’s needed to make them shine is to just make 2 changes in the Firefox via about:config.

    Those 2 changes will give me the same functionalities as the Firefox Multi-Account Containers. So that’s what I’m going to show you show to do in this post. To begin, open a tab and type about:config in the address bar. After clicking through whatever prompt or warning it throws up, type privacy.user in the search bar. The two preferences you’re looking for are privacy.userContext.enabled and privacy.userContext.ui.enabled. Figure 2 shows both preferences in their default state – false. Notice that if you long left-click the new tab (+) button before installing the Firefox Multi-Account Containers extension and with both preferences in their default state, that noting happens.

  • [Old] Migrating Technical Docs from Jekyll to Hugo+Docsy

    Recently, I migrated Graphviz'technical documentation from the Jekyll static site generator to the Hugo static site generator, and specifically the Docsy Hugo theme for technical documentation.

    I thought it would be straightforward to move static site generators, but it turned out rather difficult, so perhaps it's worth writing about. Good technical doc infra is underrated. I hope this will be useful to write about for anyone considering a move from Jekyll to Hugo, or anyone interested in an evaluation of Docsy.

  • Log backtraces at obfuscated Android methods

    If you have the source code to the app, and the app is in debug mode (not obfuscated by ProGuard), this is easy: open Android Studio, click in the left-margin of the source code to add a breakpoint, untick the "Suspend" checkbox and tick the "Logging Options – Stack trace" checkbox.

    So now, all my posts render on a single page. To help you further, posts can be filtered by category at the top of the main blog page.

    Since I don’t have any featured images being displayed in my posts feed, the page still loads really quickly. Even when rendering ~250 posts.

  • How we use the SLURM job scheduler system on our compute servers

    Our motivation for using SLURM at all is that we have a pool of compute servers of varying capacity, and some GPU servers as well. A few of these compute servers are general login servers, but the problem with these is that they're a free for all; anyone can log in at any time and start using CPU (and perhaps memory, although that can't be fair-share scheduled so it's first come, first served). Traditionally people have wanted to reserve some dedicated amount of resources that are theirs for some amount of time. Well, SLURM does that.

  • Why region based memory allocation help with fragmentation

    Overall, I think we can say that region allocation reduces fragmentation by making the order of allocating and freeing memory less important. If you intermix allocating a bunch of different sized objects and then don't free all of them (or delay freeing them for a long time), in a simple allocator you wind up with allocated holes in your free ranges. In a region allocator, those different sized allocations go to different regions, and failing to free all of the objects of one size (in one region) doesn't cause problems for other regions of other sizes.

  • Computation that needs to be "secure" is everywhere in practice

    The problem is that we have wound up with a lot of things on our devices that we want to keep confidential, or in another perspective we've wound up in a world where a lot of untrusted things have an inordinate amount of access to our devices. Cryptographic keys are the tip of the iceberg; there are also access tokens in the form of cookies, JWTs, and all of the other forms they take, URLs that we visit, apps that we use, what we type on the keyboard, and on and on and on. We are barely keeping up with identifying what's sensitive and needs to be kept confidential, never mind actually controlling snooping on it.

  7. How to enable SSH on Linux Mint

    Enabling SSH on Ubuntu is one of the first things you should do after installing the operating system as it provides an encrypted network protocol for safeguarding remote server and client logins. It allows you to access your machine remotely and execute operations securely. It encrypts all client-server traffic to prevent eavesdropping, connection hijacking, and other types of attacks.

    Secure Shell (SSH) protocol is used to manage or transmit data between computers through the internet. Old methods for accomplishing these actions, such as telnet do not have these capabilities. They are unsafe since they transmit the user’s password in plaintext. It offers a secure route over an unprotected network, connecting an SSH client program to an SSH server in a client-server architecture. It is mainly used to communicate to Unix-like operating systems, although it may also be used on Windows.

  8. How to add a user on Linux Mint

    Linux is reliable and secure compared to other operating systems, yet granting complete permissions to an unskilled user might lead to severe difficulties. This is where the administrator took control, one of the most important aspects of being a system administrator is user management. Because there are so many critical components to administrate, even the tiniest error can result in the intruders taking over the entire system. The system administrator can create, add and give each user a separate set of permissions. When a user is added or created, the appropriate level of access is granted to that user. Adding a user on Linux Mint can be accomplished in two ways; through the terminal and through GUI.

  11. What is a Tar File

    Tar is a powerful archiver that is frequently used for collecting files and archiving them. It was created to produce archives for data storage on tapes, thus the name “Tape Archive”. It was initially included in UNIX version 7 in 1979, and it is currently accessible on a variety of systems.

    Before we go into the situation’s specifics, let’s define Archive files so that no Linux newbies are left out. Archived file is a combination of multiple files with metadata information. By combining multiple files and their information into a single file, you may improve the storage and mobility of your data. The basic purpose of Tar is to combine the data but you can also compress the data using other utilities. These compressed files are referred to as Archive files, and they assist users to reduce file size and simplify data management. The tar is one of the must-have utilities for managing various files in Linux.

  • SeaMonkey 1.1.19 compiled in EasyOS

    As I seem to have settled on Firefox as the main browser in EasyOS, I still want to keep a WYSIWYG HTML editor in the build, builtin. So, my mind turned to considering old versions of SeaMonkey...
    Looking at my old notes, the 1.1 series look good. Very old, version 1.1.19 was the last, released, I think, in 2010. The 1.1 series was the last, I think, that can be configured to build a standalone composer.
    But, then, with SM you get the browser and composer editor, both, for not much increase in size. So why not build the suite. The browser could be a substitute for the 'surfer' HTML viewer that I am currently using to view local help files in Easy.

  • How to install Proxmox? - Unixcop the Unix / Linux the admins deams

    Hello, friends. In this post, you will learn how to install Proxmox on a completely clean server. For this, then I will use a virtual machine but the procedure is simple and the same as on a real physical server.

    What is Proxmox?

    Proxmox VE “Virtual Environment” is a powerful enterprise-level virtualization platform 100% free and unlimited in its use.

    Of course, it has a license that allows us to obtain additional features that facilitate the administration of it. But in general, we can use it in many of our projects for free.

    Proxmox is essentially a Debian that adds KVM virtualization and Container-based Virtualization. Therefore the whole base is Free and this makes it possible for the final product to be free. How is it supported? The proxmox business model is based on training, certifications, and support and as I mentioned an enterprise license.

    One of the main advantages of Proxmox is that it has a JavaScript web interface. This has an intuitive design where all KVM clients, Linux containers, storage units, and clusters are displayed.

    So, let’s go for it.

  • The APT package manager has been patched to prevent the uninstallation of essential components - LinuxStoney

    Last week was a bitter for bit System76 . Aside from its conflict with GNOME , the company had to see its operating system, Pop! _OS , being exposed on the YouTube channel Linus Tech Tips after an attempt to install Steam took away the desktop environment.

    Linus Sebastian, the protagonist of the Linus Tech Tips channel, tried to use or test Linux as a desktop operating system. To do this, he first opted for Pop! _OS, one of NVIDIA’s most user-friendly and graphics-friendly distributions. Everything seemed to be going apparently fine until he started installing Steam . He first tried the store, but after failing, he tried through APT. Despite the warning that jumped him, Linus decided to go ahead with the installation of the application, which resulted in the uninstallation of the desktop environment . After rebooting, obviously, there was no graphical interface.

  3. How To Change File Attributes in Linux With Chattr Command

    File attributes are certain properties that are associated with the file. The attributes allow a file to have some characteristics that are valid for all users.

    You may be familiar with the file permissions on Linux. As Linux is a multi-user operating system, it is possible to assign different file or folder permissions for different users.

    File attributes are quite similar to permissions on Linux. However, while basic permissions are only limited to read, write, and execute, the attribute allows the files or folders to have some extended sets of rules that apply on them.

    We can change or modify file/folder permissions with the chmod command. If you are not familiar with the Linux permissions, we recommend you to take a look at our comprehensive guide on the matter. Knowledge of file or folder permissions are not required to follow this tutorial.
    An important thing to remember about the attributes is that the attributes generally apply to all the users in the system (even root).

    For example, if a file were to be assigned the read-only attribute, that file would not allow any user (including root) to modify it. Obviously, the root user could modify the file, but only after removing the read-only attribute.

  4. Apt vs Apt-get Commands Explained: Which One To Use?

    As a regular Ubuntu or Debian Linux user, you might have noticed that some package installer, removal, or updating commands use the apt command instead of the apt-get command. Now, as a day-to-day Linux user, you would not get to know what they are and which command is used for what! But as a power Linux/Ubuntu user, you definitely must know the difference between apt vs apt-get commands.

    In the default command lists of Ubuntu, the apt-get command has been widely used for a long while. The new apt command was introduced a few years ago to increase the work efficiency and make the commands process simpler. Though there are some packages that only work with apt-get, hence most cache loading and cache removing or updating functions are nowadays done by the apt command.

Kernel and Graphics: Linux Stuff and GPUs

  • Facebook/Meta Tackling Transparent Page Placement For Tiered-Memory Linux Systems - Phoronix

    Back during the Linux 5.15 cycle Intel contributed an improvement for tiered memory systems where less used memory pages could be demoted to slower tiers of memory storage. But once demoted that kernel infrastructure didn't have a means of promoting those demoted pages back to the faster memory tiers should they become hot again, though now Facebook/Meta engineers have been working on such functionality.  Prior to the Linux 5.15 kernel, during the memory reclaim process when the system RAM was under memory pressure was to simply toss out cold pages. However, with Linux 5.15 came the ability to shift those cold pages to any slower memory tiers. In particular, modern and forthcoming servers with Optane DC persistent memory or CXL-enabled memory, etc. Therefore the pages are still accessible if needed but not occupying precious system DRAM if they aren't being used and to avoid just flushing them out or swapping to disk. 

  • Linux 5.17 To Boast Latency Optimization For AF_UNIX Sockets - Phoronix

    Net-next has been queuing a number of enticing performance optimizations ahead of the Linux 5.17 merge window kicking off around the start of the new year. Covered already was a big TCP optimization and a big improvement for csum_partial() that is used in the network code for checksum computation. The latest optimization is improving the AF_UNIX code path for those using AF_UNIX sockets for local inter-process communication.  A new patch series was queued up on Friday in net-next for improving the AF_UNIX code. That patch series by Kuniyuki Iwashima of Amazon Japan is ultimately about replacing AF_UNIX sockets' single big lock with per-hash locks. The series replaces the AF_UNIX big lock and also as part of the series has a speed-up to the autobind behavior. 

  • Nvidia Pascal GPU, DX12 and VKD3D: Slideshow time! - Boiling Steam

    So Horizon Zero Dawn had a sale recently on Fanatical, and I thought… OK I’ll grab it! It’s time. I first installed it on my workstation that only has a GTX1060 3GB GPU – not a workhorse but a decent card nonetheless for low-to-medium end gaming. I knew very well that Horizon Zero Dawn is a DX12 game and that Pascal architecture (Nvidia 10xx basically) and earlier versions do not play very well with DX12 games running through vkd3d-proton, the DX12 to Vulkan translation layer. Still, I could imagine getting somewhere around 30 FPS on low-to-medium settings, and use FSR if necessary to get to better framerates. Nothing prepared me for the performance I was about to experience.

Linux 5.16-rc3

So rc3 is usually a bit larger than rc2 just because people had some
time to start finding things.

So too this time, although it's not like this is a particularly big
rc3. Possibly partly due to the past week having been Thanksgiving
week here in the US. But the size is well within the normal range, so
if that's a factor, it's not been a big one.

The diff for rc3 is mostly drivers, although part of that is just
because of the removal of a left-over MIPS Netlogic driver which makes
the stats look a bit wonky, and is over a third of the whole diff just
in itself.

If you ignore that part, the statistics look a bit more normal, but
drivers still dominate (network drivers, sound and gpu are the big
ones, but there is noise all over). Other than that there's once again
a fair amount of selftest (mostly networking), along with core
networking, some arch updates - the bulk of it from a single arm64
uaccess patch, although that's mostly because it's all pretty small -
and random other changes.

Full shortlog below.

Please test,
