6 Best Log Management Tools For Linux in 2019

Filed under
Server
Software

Before we can talk about log management, let’s define what a log is. Simply defined, a log is the automatically-produced and time-stamped documentation of an event relevant to a particular system. In other words, whenever an event takes place on a system, a log is generated. Systems and devices will generate logs for different types of events and many systems give administrators some degree of control over which event generates a log and which doesn’t.

As for log management, It is simply referring to the processes and policies used to administer and facilitate the generation, transmission, analysis, storage, archiving and eventual disposal of large volumes of log data. Although not clearly stated, log management implies a centralized system where logs from multiple sources are collected. Log management is not just log collection, though. It is the management part which is the most important. And log management systems often have multiple functionalities, collecting logs being just one of them.

Once logs are received by the log management system, they need to be standardized into a common format as different systems format logs differently and include different data. Some start a log with the date and time, some start it with an event number. Some only include an event ID while others include a full-text description of the event. One of the purposes of log management systems is to ensure that all collected log entries are stored in a uniform format. This will event correlation and eventual searching much easier down the line.

Even correlation and searching are two additional major functions of several log management systems. The best of them feature a powerful search engine that allows administrators to zero-in on precisely what they need. Correlation functions will automatically group related events, even if they are from different sources. How—and how successfully—different log management system accomplish that is a major differentiating factor.

Linux
Software

It’s a frustrating reality for Linux users that Windows software counterparts tend to be better. They may offer greater functionality, better design, and be easier-to-use. There are some exceptions, such as with the NVIDIA Linux GPU driver, which offers two features the Windows version doesn’t: temperature monitoring, and fan control. For the most part, though, things like driver control panels are a scarcity in Linux.

Gammy: Adaptive Screen Brightness Tool For Linux

Filed under
Software

Gammy, an adaptive screen brightness GUI tool that that was originally only available for Microsoft Windows, was ported to Linux (X11 only) recently.

The Qt5 application takes a screenshot periodically, then gradually adjusts the pixel brightness based on the screen (screenshot) contents, dimming the screen if its content is too bright, or brightening the screen if its content is too dark. This is especially useful for reducing eye strain when switching between dark and light windows.

The Gammy settings allows setting a minimum and maximum brightness, and an offset (the offset adds to the screen brightness, with a higher value meaning a brighter image). Also, because it conflicts with Redshift, the Gammy developer decided to add basic temperature control, which you'll also find in the application settings.

Ubuntu

There are a lot of free and open-source video players available for Ubuntu. Most of them do the basic job pretty well and you do not miss anything from Windows that you could use on Ubuntu. However, some players provide additional features and you can pick which one would suit you best depending on the feature list. In this article, we will give you an introduction to some famous video players for Ubuntu. We will also tell you where to find their websites and how to install them on Ubuntu. All of these players can be reliably downloaded graphically from the Ubuntu Software but we will also explain other methods of installation for educational purposes. Also, some methods let you install the latest available version of the software from the Internet so we will not miss out on those.

Flameshot is a brilliant screenshot tool for Linux

Filed under
Software

The default screenshot tool in Ubuntu is alright for basic snips but if you want a really good one you need to install a third-party screenshot app.

Shutter is probably my favorite, but I decided to give Flameshot a try. Packages are available for various distributions including Ubuntu, Arch, openSuse and Debian. You find installation instructions on the official project website.

Akaunting: a web-based accounting system

Filed under
Software
Reviews

One of these years, LWN will have a new accounting system based on free software. That transition has not yet happened, though, despite the expending of a fair amount of energy into researching alternatives. Your editor recently became aware of a system called Akaunting, so a look seemed worthwhile. This tool may have the features that some users want, but it seems clear that your editor's quest is not done yet.

As an aside, additional motivation for this effort came in the form of an essentially forced upgrade to QuickBooks 2019 — something that QuickBooks users have learned to expect and dread. There appear to be no new features of interest in this release, but it does offer a newly crippled data import mechanism and routine corruption of its database. If your editor didn't know better, he might just conclude that proprietary software is buggy, unreliable, and unfixable.

[...]

The system is written in PHP and JavaScript; the code is licensed under GPLv3. Akaunting is able to use MySQL, PostgreSQL, or SQLite to store the actual data. It is, as one might expect given the implementation languages, designed to run as a web application; one can install it on a handy machine, but Akaunting (the company) also offers to host accounts free of charge on its own servers. The company promises "we cover it, for free, forever" — a pretty big promise for a free-software startup with a minimal track record.

The ability to share files regardless of the physical distance and almost instantaneously is one of the greatest characteristics of the Internet. With 4.3 billion Internet users at the beginning of 2019, the amount of data transferred over the Web is almost unimaginable.

But not all file-sharing services are created equal. In the era where personal data is the most valuable currency we can spend, it is important to ensure we send files over the Internet in a secure and anonymous way.

Read to find out why mainstream file-sharing services are not your best bet and how to pick an alternative solution.

Announcing notqmail

Okay, that’s not entirely true. While qmail hasn’t been updated by its original author, a group of respected users created netqmail, a series of tiny updates that were informed, conservative, and careful. By their design, it was safe for everyone running qmail to follow netqmail, so everyone did. But larger changes in the world of email — authentication, encryption, and ever-shifting anti-spam techniques — remained as puzzles for each qmail administrator to solve in their own way. And netqmail hasn’t been updated since 2007.

7 Great Linux Statistical Analysis Tools

Sci/Tech

Science is the effort of seeking to comprehend how the physical world works. From observation and experimentation, science uses physical evidence of natural phenomena to compile data and analyze the collated information.

In modern research it is essential for scientists to keep abreast of the latest statistical software. Just like the fast moving world of research, developments in statistical software and methods continue to abound. Making full use of the improvements in computer software helps to advance the pace of research.

Science really prospers and advances when individuals share the results of their experiments with others in the scientific community. There is a certain logic that scientific software should therefore be released in a freely distributable environment.

Linux is particularly strong in the field of open source statistical software. The purpose of this article is to identify software for performing statistical analysis. This type of software helps to summarize data in a shorter form, and helps scientists understand a concept or representation and make possible predictions based on this understanding.

  • TSDgeos' blog: Akademy 2019

    It's 10 days already since Akademy 2019 finished and I'm already missing it :/ Akademy is a week-long action-packed conference, talks, BoFs, daytrip, dinner with old and new friends, it's all a great combination and shows how amazing KDE (yes, the community, that's our name) is. On the talks side i missed some that i wanted to attend because i had to extend my time at the registration booth helping fellow KDE people that had forgotten to register (yes, our setup could be a bit easier, doesn't help that you have to register for talks, for travel support and for the actual conference in three different places), but I am not complaining, you get to interact with lots of people in the registration desk, it's a good way to meet people you may not have met otherwise, so please make sure you volunteer next year ;) One of the talks i want to highlight is Dan VrĂĄtil's talk about C++, I agree with him that we could do much better in making our APIs more expressive using the power of "modern" C++ (when do we stop it calling modern?). It's a pity that the slides are not up so you'll have to live with KĂŠvin Ottens sketch of it for now.

  • Getting started with data science using Python

    Data science is an exciting new field in computing that's built around analyzing, visualizing, correlating, and interpreting the boundless amounts of information our computers are collecting about the world. Of course, calling it a "new" field is a little disingenuous because the discipline is a derivative of statistics, data analysis, and plain old obsessive scientific observation. But data science is a formalized branch of these disciplines, with processes and tools all its own, and it can be broadly applied across disciplines (such as visual effects) that had never produced big dumps of unmanageable data before. Data science is a new opportunity to take a fresh look at data from oceanography, meteorology, geography, cartography, biology, medicine and health, and entertainment industries and gain a better understanding of patterns, influences, and causality. Like other big and seemingly all-inclusive fields, it can be intimidating to know where to start exploring data science. There are a lot of resources out there to help data scientists use their favorite programming languages to accomplish their goals, and that includes one of the most popular programming languages out there: Python. Using the Pandas, Matplotlib, and Seaborn libraries, you can learn the basic toolset of data science.

Excellent Utilities: Liquid Prompt – adaptive prompt for Bash & Zsh

This is a new series highlighting best-of-breed utilities. We’re covering a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides. There’s a complete list of the tools in this series in the Summary section. The Command Line Interface (CLI) is a way of interacting with your computer. And if you ever want to harness all the power of Linux, it’s highly recommended to master it. It’s true the CLI is often perceived as a barrier for users migrating to Linux, particularly if they’re grown up using GUI software exclusively. While Linux rarely forces anyone to use the CLI, some tasks are better suited to this method of interaction, offering inducements like superior scripting opportunities, remote access, and being far more frugal with a computer’s resources. For anyone spending time at the CLI, they’ll rely on the shell prompt. My favorite shell is Bash. By default, the configuration for Bash on popular distributions identifies the user name, hostname, and the current working directory. All essential information. But with Liquid Prompt you can display additional information such as battery status, CPU temperature, and much more. Read more
