At How can I find tomorrow's or yesterday's date in a script?, some anonymous person left what I consider to be a stupid comment. In this case, the answer (one answer) was right on on the page itself.

Access your MySQL database for maintenance without a password

Filed under
HowTos

One important part of running a database is maintenance, and that includes backups. However, due to the fact that the database is password-protected, one can't automatically back up the database without interactively supplying the password. You can avoid those hassles by creating a configuration file for the user to do the backups.

Encrypt filesystems with EncFS and Loop-AES

Filed under
HowTos

Encrypted filesystems may be overkill for family photos or your résumé, but they make sense for network-accessible servers that hold sensitive business documents, databases that contain credit-card information, offline backups, and laptops. EncFS and Loop-AES, which are both released under the GNU General Public License (GPL), are two approaches to encrypting Linux filesystems. I'll compare the two and then look at other alternatives.

Today I started to set up a SVN repository for our final year project. I tried to setup a SVN server using Apache2 so that the SVN repository is available to the client through the WebDAV/DeltaV protocol. Read on for a trial-and-error introduction.

CLI Magic: Tracking system performance with sar

Filed under
HowTos

Sar is the "system activity report" program found on *nix systems. In Linux, you can usually find it in the sysstat package, which includes programs and scripts to capture and summarize performance data, then produce detailed reports. This suite of programs can be useful in tracking down performance bottlenecks and providing insight into how the system is used throughout the day.

Preventing DDOS Attacks

Filed under
HowTos

DDOS happens due to lack of security awareness of the network/server owners. On a daily basis we hear that a particular machine is under DDOS attack or NOC has unplugged the machine due to DDOS attack. In this article I am trying to explain what DDOS is and how it can be prevented.

EU Law Threatens Free/Open Source Software

  • EU votes on copyright law that could kill memes and open source software
    The European Union has passed an initial vote in favour of the Copyright Directive, a legislation experts say "threatens the internet". As reported by Wired, the mandate is designed to update internet copyright law but contains two controversial clauses. Ultimately, it could force prominent online platforms to censor their users' content before it's posted—which could impact everyone from meme creators to open source software designers and livestreamers. Despite passing a vote yesterday—held by the EU's Legal Affairs Committee (JURI)—the directive needs parliamentary approval before becoming law.
  • The EU Parliament Legal Affairs Committee Vote on Directive on Copyright, David Clark Cause and IBM's Call for Code, Equus' New WHITEBOX OPEN Server Platform and More
    Yesterday the European Parliament Legal Affairs Committee voted in favor of "the most harmful provisions of the proposed Directive on Copyright in the Digital Single Market", Creative Commons reports. The provisions include the Article 11 "link tax", which requires "anyone using snippets of journalistic content to first get a license or pay a fee to the publisher for its use online." The committee also voted in favor of Article 13, which "requires online platforms to monitor their users' uploads and try to prevent copyright infringement through automated filtering." There are still several steps to get through before the Directive is completely adopted. See EDRi for more information.

  • The E.U. votes to make memes essentially illegal
    On Wednesday, European Parliament’s Committee on Legal Affairs voted to essentially make memes illegal. The decision came as part of the approval process for the innocuously named “Article 13,” which would require larger sites to scan all user uploads using content recognition technology in an attempt to flag any and all remotely copyrighted material in photos, text, music, videos, and more. Meaning memes using stills from copyrighted films could be auto-blocked, along with remixes of viral videos, and basically anything that’s popular on live-streaming sites like Twitch.
  • Europe takes step towards 'censorship machines' for internet uploads
    A key committee at the European Parliament has voted for a new provision in a legislative act that forces tech giants and other online platforms to share revenues with publishers. It is known as Article 13, and is part of an updating of the Copyright Directive. Article 13 proposes that large websites use “content recognition technologies” to scan for copyrighted materials, though it doesn’t explain how this works in practice. This means texts, sounds and even code which get uploaded have to go through an automated filtering system, potentially threatening the creation of memes and open-source software developers.

The EC’s Expected Decision Against Android Is an Unfortunate Attack on Open Source Software

The European Commission (“EC”) is preparing to release its decision against Android, and its framing of the issues makes clear that successful open source software will have a hard time in Europe. In its Statement of Objections, the Commission signaled that Apple’s iOS, Android’s fiercest rival, would be excluded from the market definition because it is closed source and not available to other hardware makers. The decision is expected to declare unlawful strategies to monetize a free product, provide a consistent user experience to customers expecting the Google brand, and to maintain code consistency to minimize problems for developers using the platform. The decision is not expected to contain any indication on how open source platform developers can solve these problems that are fundamental to their success. Read more

  • Five Common Chromebook Myths Debunked
    When Chromebooks first came out in 2011, they were basically just low-spec laptops that could access web apps – fine for students maybe, but not to be regarded as serious computers. While they’ve become more popular (the low cost, simplicity, and dependability appeal to businesses and education systems), as of 2018 Chromebooks still haven’t managed to become widely accepted as a Windows/Apple/Linux alternative. That may be about to change. The humble Chromebook has gotten a lot of upgrades, so let’s get ourselves up to speed on some things that just aren’t true anymore. [...] The 2011 Chrome OS was pretty bare-bones, but it’s gone to the opposite extreme since then. Not only is it steadily blurring the line between Chrome and Android, it can now install and run some Windows programs as well, at the same time as a Chrome and an Android app, if you like. And hey, while you’re at it, why not open a Linux app as well? You can already install Linux on a Chromebook if you want, but one of the next versions of Chrome OS is going to include a Linux virtual machine accessible right from your desktop (which is already possible, just not built-in and user-friendly). In sum, Chrome OS has gone from barely being an operating system to one that can run apps from four other OSes at the same time.
