Disk usage analysis and cleanup tools

Filed under
HowTos

Most of us use our hard disks like closets, stuffing in files and then forgetting about them. But no matter how big a disk you have, it's going to run out of free space one day, and running out of disk space during an OpenOffice.org install or a system update could hurt you badly. Keeping an eye on disk usage doesn't take much time or effort. Here are some tips and tools.

Installing, configuring firewalls, packet filtering in RHEL4

Filed under
HowTos

So, you want to install a firewall on your Linux-based infrastructure, but you're hung up in the research phase.

Open source project to take Ajax mainstream

Filed under
OSS

The goal of Open Ajax is to standardize around a common set of widgets, interfaces, and plug-ins to Eclipse so it can morph into an industrial strength rich web development environment. And with the standards, any Eclipse-compliant Ajax toolkit should be able to plug into any compliant Ajax run time, regardless of browser client or server deployment platform.

Book Review -- The Debian System: Concepts and Techniques

Filed under
Reviews

Martin Krafft's The Debian System: Concepts and Techniques is not a general introduction to GNU/Linux. Instead, the book focuses only on Debian-specific concepts and tools. I found little overlap between the material in this book and several general Linux-related books I already own. From fundamental concepts to advanced techniques, most topics in this book are covered in great depth, so it is likely to have a long shelf-life on most readers' bookshelves.

Configuring Dynamic DNS & DHCP on Debian Stable

Filed under
HowTos

For the average home computer user there is no need to install a complex package such as the Internet Software Consortium's BIND DNS or DHCP server, since there are far simpler lower resource tools to use, for example dnsmasq. For those who you wish to learn how to use ISC's BIND and DHCP, for example as a learning exercise, this is how I got it all to work in Debian Sarge, the current stable version of Debian GNU/Linux.

Connecting to existing databases in OpenOffice.org 2.0

Filed under
HowTos

In the glamorous world of office suites, the new features often get all the attention. The Bases, the Impress Redux and the New Toolbar Metaphors of OpenOffice.org 2.0 get all the cover stories and the center spreads in Office Suite Weekly, while the slight changes that make life easier often get ignored. It's a sad story.

I'm here to change that; a bit, at least.

First Release Candidate of Linux 5.3

  • Linux 5.3-rc1
    It's been two weeks, and the merge window is over, and Linux 5.3-rc1
    is tagged and pushed out.
    
    This is a pretty big release, judging by the commit count. Not the
    biggest ever (that honor still goes to 4.9-rc1, which was
    exceptionally big), and we've had a couple of comparable ones (4.12,
    4.15 and 4.19 were also big merge windows), but it's definitely up
    there.
    
    The merge window also started out pretty painfully, with me hitting a
    couple of bugs in the first couple of days. That's never a good sign,
    since I don't tend to do anything particularly odd, and if I hit bugs
    it means code wasn't tested well enough. In one case it was due to me
    using a simplified configuration that hadn't been tested, and caused
    an odd issue to show up - it happens. But in the other case, it really
    was code that was too recent and too rough and hadn't baked enough.
    The first got fixed, the second just got reverted.
    
    Anyway, despite the rocky start, and the big size, things mostly
    smoothed out towards the end of the merge window. And there's a lot to
    like in 5.3. Too much to do the shortlog with individual commits, of
    course, so appended is the usual "mergelog" of people I merged from
    and a one-liner very high-level "what got merged". For more detail,
    you should go check the git tree.
    
    As always: the people credited below are just the people I pull from,
    there's about 1600 individual developers (for 12500+ non-merge
    commits) in this merge window.
    
    Go test,

  • Linux 5.3-rc1 Debuts As "A Pretty Big Release"

    Just as expected, Linus Torvalds this afternoon issued the first release candidate of the forthcoming Linux 5.3 kernel. It's just not us that have been quite eager for Linux 5.3 and its changes. Torvalds acknowledged in the 5.3-rc1 announcement that this kernel is indeed a big one: "This is a pretty big release, judging by the commit count. Not the biggest ever (that honor still goes to 4.9-rc1, which was exceptionally big), and we've had a couple of comparable ones (4.12, 4.15 and 4.19 were also big merge windows), but it's definitely up there."

  • The New Features & Improvements Of The Linux 5.3 Kernel

    The Linux 5.3 kernel merge window is expected to close today so here is our usual recap of all the changes that made it into the mainline tree over the past two weeks. There is a lot of changes to be excited about from Radeon RX 5700 Navi support to various CPU improvements and ongoing performance work to supporting newer Apple MacBook laptops and Intel Speed Select Technology enablement.

today's howtos and programming bits

  • How to fix Ubuntu live USB not booting
  • How to Create a User Account Without useradd Command in Linux?
  • Container use cases explained in depth
  • Containerization and orchestration concepts explained
  • Set_env.py

    A good practice when writing complicated software is to put in lots of debugging code. This might be extra logging, or special modes that tweak the behavior to be more understandable, or switches to turn off some aspect of your test suite so you can focus on the part you care about at the moment. But how do you control that debugging code? Where are the on/off switches? You don’t want to clutter your real UI with controls. A convenient option is environment variables: you can access them simply in the code, your shell has ways to turn them on and off at a variety of scopes, and they are invisible to your users. Though if they are invisible to your users, they are also invisible to you! How do you remember what exotic options you’ve coded into your program, and how do you easily see what is set, and change what is set?

  • RPushbullet 0.3.2

    A new release 0.3.2 of the RPushbullet package is now on CRAN. RPushbullet is interfacing the neat Pushbullet service for inter-device messaging, communication, and more. It lets you easily send alerts like the one to the left to your browser, phone, tablet, … – or all at once. This is the first new release in almost 2 1/2 years, and it once again benefits greatly from contributed pull requests by Colin (twice !) and Chan-Yub – see below for details.

  • A Makefile for your Go project (2019)

    My most loathed feature of Go was the mandatory use of GOPATH: I do not want to put my own code next to its dependencies. I was not alone and people devised tools or crafted their own Makefile to avoid organizing their code around GOPATH.

  • Writing sustainable Python scripts

    Python is a great language to write a standalone script. Getting to the result can be a matter of a dozen to a few hundred lines of code and, moments later, you can forget about it and focus on your next task. Six months later, a co-worker asks you why the script fails and you don’t have a clue: no documentation, hard-coded parameters, nothing logged during the execution and no sensible tests to figure out what may go wrong. Turning a “quick-and-dirty” Python script into a sustainable version, which will be easy to use, understand and support by your co-workers and your future self, only takes some moderate effort.

The Status of Fractional Scaling (HiDPI) Between Windows & Linux

There’s a special type of displays commonly called “HiDPI“, which means that the number of pixels in the screen is doubled (vertically and horizontally), making everything drawn on the screen look sharper and better. One of the most common examples of HiDPI are Apple’s Retina displays, which do come with their desktops and laptops. However, one issue with HiDPI is that the default screen resolutions are too small to be displayed on them, so we need what’s called as “scaling”; Which is simply also doubling the drawn pixels from the OS side so that they can match that of the display. Otherwise, displaying a 400×400 program window on a 3840×2160 display will give a very horrible user experience, so the OS will need to scale that window (and everything) by a factor of 2x, to make it 800×800, which would make it better. Fractional scaling is the process of doing the previous work, but by using fractional scaling numbers (E.g 1.25, 1.4, 1.75.. etc), so that they can be customized better according to the user’s setup and needs. Now where’s the issue, you may ask? Windows operating system has been supporting such kind of displays natively for a very long time, but Linux distributions do lack a lot of things in this field. There are many drawbacks, issues and other things to consider. This article will take you in a tour about that. Read more Also: Vulkan 1.1.116 Published With Subgroup Size Control Extension
