Software: Taskbook, ngrep, mdl s-tui and more

  • Taskbook is a Board-based Task Manager for the Command Line

    If you’re looking to stay productive at the command line you’ll want to check out Taskbook.

    Taskbook is a terrifically well made terminal app that lets you create todo lists, jot down notes, and organise your tasks using boards.

    Hacker News described it as “Like Trello but for the Terminal”, a description that isn’t entirely accurate.

    Taskbook is more akin to a plain text to-do list tool than it is a Trello analog for the terminal.

    For instance, it lacks the spatial flow of Trello, i.e. being able to see all of your columns side by side, and there’s no team collaboration features, tagging, or other advanced features.

  • ngrep – A Network Packet Analyzer for Linux

    Ngrep (network grep) is a simple yet powerful network packet analyzer. It is a grep-like tool applied to the network layer – it matches traffic passing over a network interface. It allows you to specify an extended regular or hexadecimal expression to match against data payloads (the actual information or message in transmitted data, but not auto-generated metadata) of packets.

    This tool works with various types of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP as well as Raw on a number of interfaces. It operates in the same fashion as tcpdump packet sniffing tool.

  • mdl

    The last month I wrote a blog post about the LMDB Cache database and my wish to use that in Fractal. To summarize, LMDB is a memory-mapped key-value database that persist the data to the filesystem. I want to use this in the Fractal desktop application to replace the current state storage system (we're using simple json files) and as a side effect we can use this storage system to share data between threads because currently we're using a big struct AppOp shared with Arc> and this cause some problems because we need to share and lock and update the state there.

    The main goal is to define an app data model with smaller structs and store this using LMDB, then we can access to the same data querying the LMDB and we can update the app state storing to the LMDB.

    With this change we don't need to share these structs, we only need to query to the LMDB to get the data and the work with that, and this should simplify our code. The other main benefit will be that we'll have this state in the filesystem by default so when we open the app after close, we'll stay in the same state.

  • s-tui: CPU Monitoring And Stress Testing Console UI Tool

    Besides monitoring your CPU using colored graphs, the TUI (terminal user interface) application can also stress test your CPU using stress or stress-ng. The stress test is configurable, allowing you to specify parameters like time out, Sqrt() and Sync() worker count, Malloc() / Free() worker count, and more.

    s-tui can also integrate with FIRESTARTER, a process stress test utility, though note that this requires building s-tui from source, and apparently FIRESTARTER doesn't work on all systems.

    The 4 graphs (CPU temperature, utilization, power and frequency) displayed by s-tui can be toggled on / off, and in the s-tui sidebar (you may need to scroll down in its sidebar if the terminal is not full-screen) you'll find the top and current CPU frequency, maximum and current temperature, current fan speed, and maximum and current power:

  • ​Opera is available in a Snap on Linux

    They've done this by packing Opera into a Snap in the Snap Store. The Opera snap is supported on Debian, Elementary, Fedora, Linux Mint, Manjaro, OpenSUSE, Ubuntu, and other Linux distributions.

    Snaps are containerised software packages. They're designed to work securely within any Linux environment across desktop, the cloud, and IoT devices. Thousands of snaps have been launched since 2016. Users like them because they come with automatic updates and roll-back features.

    Snaps also are a bit more secure than most Linux apps. They make it easier for developers to roll out their programs. When your program in encased in a Snap, you don't need to worry about the distribution's native packaging or whether the desktop distro includes a vital library your application needs.

Finding alternatives to proprietary online tools with Framasoft

Filed under

You can’t escape Google. At least, that’s how it seems.

The company doesn’t just dominate search. It also has its tendrils in personal storage, online productivity tools, books, music, social networking, and more. Billions of people the world over use their services because of the convenience and power.

The flip side? Google, and other online providers like them, collect a massive amount of data about you and your online habits, and it isn't always clear what companies do with that all that data. This is causing more people to look for alternatives to these "free" tools, but many don’t know where to find them.

Framasoft, a non-profit network dedicated to the global promotion of free (as in free speech) software and culture, wants to help people de-Googlize their online lives.

Thanks to the miracle that’s Etherpad, I was able to sit down (virtually) with the team from Framasoft to learn more about what they do and why they do it.

    We hereby present you the third and last alpha build of Kodi v18 as we are going forward entering beta stage. This release is a continuation of the previous two with our continous focus on solving bugs and usability problems. So far it has proved to be quite solid to use as a daily driver for those who were brave enough to try it out. Of course you should still keep in mind it's not a final release yet and that on any upgrade a small glitch could happen as we are still doing rework. Once you decide to give it a try it is highly recommended that you create a backup first.

Best Health And Fitness Tools For Linux

Filed under

No matter which type of profession you are in, a busy schedule might interfere with your fitness goal. Some professionals have to work beyond the scheduled time than 8AM to 5PM job. Moreover, some might have regular weekend and home assignments. This ever-growing group of workers today and their commitments and timetables made it difficult to maintain a proper schedule for dieting and focusing on some physical fitness exercises.

So living inside a busy schedule it has become a challenge to keep track of what we do, what we eat and how our heart works.

Thanks to technology for the beautiful gift of fitness tracker that have come a long way for which now Linux professionals or home-users can keep track of what portion of their daily workouts have been completed and what needs to be done, any time, right on our reach.

As an avid Linux user, I've personally used few tools that have been proved helpful to stay healthy by getting me used to ergonomic habits. Let me name some of the best native Linux apps for fitness.

  • GUI ways to view and edit big text files

    I do my data auditing on the command line, but it's sometimes nice to have the kind of overview of the data that you get with a spreadsheet. Unfortunately, this isn't possible with seriously large data tables. The current table size limits in Microsoft Excel are 1,048,576 rows, 16,384 columns and 32,767 characters per cell. LibreOffice Calc has the same row and character limits but tops out at 1,024 columns. Gnumeric (my favourite spreadsheet) allows 16,777,216 rows and 16,384 columns.

    These limits, however, don't mean much for big datasets. How efficiently a spreadsheet works is determined by your system's memory resources and by the nature of your data items. Not only might it take an annoyingly long time for a big table to open as a spreadsheet, but operations like searching, moving around, global editing and file saving can then be annoyingly slo-o-o-o-o-ow.

    GUI spreadsheets are impractical, in my experience, for viewing or editing tables with more than about 50,000 rows and 100 columns. Four viewing/editing alternatives for Linux are noted below; in the screenshots I've reduced their GUI window sizes to suit this blog's column width. Missing from the list is UltraEdit for Linux, a very capable GUI text editor which (last time I checked) cost USD$100 per copy.

  • Fping – A High Performance Ping Tool for Linux

    fping is a small command line tool to send ICMP (Internet Control Message Protocol) echo request to network hosts, similar to ping, but much higher performing when pinging multiple hosts. fping totally differs from ping in that you can define any number of hosts on the command line or specify a file with the list of IP addresses or hosts to ping.

  • What Really IRCs Me: Slack

    I'm an IRC kind of guy. I appreciate the simplicity of pure text chat, emoticons instead of emojis, and the vast array of IRC clients and servers to choose from, including the option to host your own. All of my interactive communication happens over IRC either through native IRC channels (like #linuxjournal on Freenode) or using a local instance of Bitlbee to act as an IRC gateway to other chat protocols. Because my IRC client supports connecting to multiple networks at the same time, I've been able to manage all of my personal chat, group chat and work chat from a single window that I can connect to from any of my computers.

    Before I upgraded to IRC, my very first chat experience was in the late 1990s on a web-based Java chat applet, and although I hold some nostalgia for web-based chat because I met my wife on that network, chatting via a web browser just seems like a slow and painful way to send text across the internet. Also, shortly after we met, the maintainers of that network decided to shut down the whole thing, and since it was a proprietary network with proprietary servers and clients, when they shut it down, all those chat rooms and groups were lost.

    Remember earlier this month when GCC's long in the works conversion from SVN to Git was being held up by the lack of RAM on Eric S Raymond's system? Well, it turns out that's just part of the problem.

    While earlier this month he thought he solved the last technical bug that was blocking the repository conversion and just needed more DDR4 RAM so his software could handle the complete GCC conversion into Git, that wasn't entirely the case. Recently he provided another update that began with, "That light at the end of the tunnel turned out to be an oncoming train."

Linux Apps Land On Beta Channel For A Lot Of Chromebooks

A recent update to the Beta Channel of Chrome OS has brought with it a very exciting surprise. The “Crostini Project,” a.k.a. Linux Apps on Chrome OS has been floating around the Developer Channel for some time and can be found on various devices such as the Pixelbook, Kaby Lake Chromeboxes and even Apollo Lake EDU Chromebooks. Unfortunately, for those wanting to try out the new feature, moving to the sometimes-unstable Developer Channel was a requirement along with enabling the “Crostini” switch that has been hidden behind a flag. The update to Chrome OS version 69.0.3497.35 in the Beta channel has not only advanced the Crostini Project but set Linux apps on by default meaning no need to enable any experimental flags. Read more
