ps_mem Shows Per-Program Memory Usage On Linux

Filed under
GNU
Linux

Unlike many other tools that report memory usage per process, ps_mem reports the RAM usage of programs. For example it shows how much RAM is used by all Chromium processes combined. The program developer notes that the ps_mem name is used for backwards compatibility, but a more accurate name would be coremem.

The displayed RAM is calculated by adding the sum of private RAM and the sum of shared RAM for a program processes.

Running ps_mem with no arguments shows a list programs and their RAM usage in ascendant order (from the lowest RAM usage to the highest). For each program it shows the private, shared, and total used RAM, as well as the number of processes. Swap information for each program can be shown as well, by using the -S option (sudo ps_mem -S).

The Great GNU/Linux Division

Linux

I have not abandoned the language of the purists altogether. For instance, I still refer to my distribution of choice as ?Debian GNU/Linux,? because that is what project members prefer. Similarly, if an FSF employee asks that I use their preferred term, I will usually agree if I think the story I?m covering is one in which people should know the difference.

What has changed is my refusal to be overly-concerned about such matters of language. While language issues were worth discussing 20 years ago, the inability to move beyond them is obsessive and crankish today. If the purists really want to help free software, they would be more useful contributing to the project of their choice than clinging a cause that was lost years ago.

Security

Password managers are applications created to enable users to keep their passwords in a single place and absolve themselves of the need to remember every single one of their passwords.

They, in turn, encourage clients to use passwords that are as complex as possible and remember a single master password. Modern password managers even go an extra mile to keep other information such as card details, files, receipts, etc. safely locked away from prying eyes.

You might be wondering which password manager app will work best on your Linux machine and I am here to answer your question with my list of the 10 best Linux password managers.

There are plenty of web browsers for Linux these days, but not all of them support all distros. This makes it a little bit difficult to choose, but there are some viable options that still work with the ecosystem. The choice isn’t just dependent on your Linux distribution, but also on your preferred use cases.

While Linux desktops offer most of the web browsers you’d use on Windows and Mac, there are some lesser-known browsers that aren’t available for the latter two operating systems.

Our top four picks for the best browsers you can use on Linux support the majority of most top distros, but your distro’s performance may vary for each of these browsers.

Here are four of the best web browsers for Linux.

Apache: AirFlow, PLC4X and Market Share

  • Whirl Adds Local AirFlow Development Technique
    Apache Airflow is a workflow automation and scheduling system that you can use to set up and manage data pipelines. It uses workflows made of directed acyclic graphs (DAGs) of tasks. Each task produces some output that is then used as the input to another task. The idea of Whirl is to make it easy to run and develop Airflow workflows on your local machine. This gives you rapid feedback about whether the changes you made to your DAG work. The developers suggest you think of it as your integration test environment for developing Airflow DAGs.
  • The Apache Software Foundation Announces Apache® PLC4X™ as a Top-Level Project
    The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 350 Open Source projects and initiatives, announced today Apache® PLC4X™ as a Top-Level Project (TLP). Apache PLC4X also has the designation as being the 200th project to graduate from the Apache Incubator. Apache PLC4X is a universal protocol adapter for creating Industrial IoT applications through a set of libraries that allow unified access to a wide range of industrial programmable logic controllers (PLCs) using a variety of protocols with a shared API. The project was originally developed at codecentric AG, and entered the Apache Incubator in December 2017.
  • April 2019 Web Server Survey
    Despite the overall loss of sites this month, nginx gained 22.3 million websites and 2.03 million additional active sites. nginx also gained the largest number of web-facing computers, increasing its total by 63,000 to 2.57 million (+2.52%). nginx's market share of web-facing computers is now nearly 30%, and this is continuing to grow steadily closer to Apache's leading share of 37.3%. Microsoft and Apache lost shares in every headline metric this month, with both vendors contributing significantly to this month's overall loss of sites. Microsoft lost 18.9 million sites, while Apache lost 17.2 million, causing their shares to decrease by 1.01 and 0.87 percentage points. These changes have pushed nginx into the lead, giving it a 27.5% share of all sites in Netcraft's April 2019 Web Server Survey. Significantly, this is the first time since 1996 that a vendor other than Microsoft or Apache has served the largest number of websites.

Games: Farm Life, ProtoCorgi, Teeworlds, Sigma Theory: Global Cold War, Steam on Ubuntu 19.04, Optimizations For Mesa 19.1

  • Farm Life, the Match 3 game about restoring a farm has been released for Linux and it's lovely
    Great to see another Match 3 game on Linux with Farm Life, ported over by Bearded Giant Games as part of their Linux 1st Initiative. I had the pleasure of testing this one before releasing and it's sucked away hours from me! Not a genre I play too often, partly because there's not many good Match 3 games available on Linux, so for me this does fill a little hole. Although I will fully admit that I was horribly addicted to Candy Crush on Android a few years ago.
  • The shoot 'em up 'ProtoCorgi' now has an updated demo, which is also on Steam for Linux too
    In ProtoCorgi you're a pup that means business, serious business. You play as Bullet, a cybernetic pup on a quest to save your owner. Since I tested the original demo, it's had a pretty large update reworking some systems which you can find a full changelog of here. This Godot Engine powered shoot 'em up is very promising, so I'm looking forward to seeing the full game. What the demo offers is obviously quite short, as it's only meant as a taster of what's to come
  • Teeworlds, the classic free multiplayer platform battler is still being updated and it's looking good
    Teeworlds, a game that's been around for a great many years now continues to be improved and updated with another update pushed out recently. For those who've never played it, Teeworlds is a side-scrolling platform action game played online across various game modes like deathmatch, team deathmatch and capture the flag. It's free, it's also open source (GitHub) and if you manage to get a bunch of people together to play with, it can be seriously fun.
  • The near-future game of espionage 'Sigma Theory: Global Cold War' is out in Early Access
    Developed by Mi-Clos Studio (Out There) and Goblinz Studio (Robothorium, Dungeon Rushers), Sigma Theory: Global Cold War, a game about using special agents to attempt control of the world has entered Early Access with Linux support recently. In the near-future scientists made a discovery called the Sigma Theory, which could throw the world into complete chaos. Apparently it's capable of helping to create new weapons of insane power, as well as tools that could disrupt everything from the economy to the human mind. Sounds pretty wild, so naturally everyone wants a piece of the pie.

    There is just one week to go until the Mesa 19.1 feature freeze and branching for this next quarterly feature update to these open-source OpenGL/Vulkan Linux drivers. Notable this round is the introduction of the Intel "Iris" Gallium3D driver for supporting Broadwell graphics and newer atop this next-gen OpenGL driver ahead of next year's Xe Graphics dGPU launch. With days to go until the Mesa 19.1 feature freeze, more performance optimizations have landed. Kenneth Graunke of the Intel Open-Source Technology Center who has led the Iris Gallium3D driver development for more than the past year pushed a number of notable improvements into Mesa Git today. iris: Track valid data range and infer unsynchronized mappings - On Skylake graphics this improves the FPS average for games like DiRT Rally, Bioshock Infinite, and Shadow of Mordor by 2~7% and the max FPS by as much as 9~20%.
