  • Tokenization, Stemming, and Lemmatization with SpaCy Library

    In the previous article, we started our discussion about how to do natural language processing with Python. We saw how to read and write text and PDF files. In this article, we will start working with the spaCy library to perform a few more basic NLP tasks such as tokenization, stemming and lemmatization.

  • Next C++ workshop: Classes and Arrays, 14 March at 19:00 UTC

    Yes, it’s that time again! You can improve your C++ skills with the help of LibreOffice developers: we’re running regular workshops which focus on a specific topic, and are accompanied by a real-time IRC meeting. For the next one, the topics are Classes and Arrays. Start by watching this presentation:

  • This Week in Rust 277

    Always wanted to contribute to open-source projects but didn't know where to start? Every week we highlight some tasks from the Rust community for you to pick and get started!

  • Further modifying the stock and forex application

    In this chapter we will continue to develop our Forex and Stock application. We have created a method to retrieve and plot the stock value vs time interval on a graph in the previous chapter and in this chapter we will create a combo box and populate it with the stock symbols so a user can select any stock he wishes to plot before calling the plot stock exchange method again.

  • Exit the game on the main menu page or during the game stage

    In this chapter we will edit the main file of the pygame project so when we click on the ?x? button on the top right of the game window during the game stage or we click on the exit button on the main menu page, the current game level will be saved and the game will exit. The position of the exit button on the start scene class remains unchanged so the only file we need to edit is the main file where we will create an exit button rectangle which will be used to determine whether the exit button has been clicked or not, if so then the game will exit. Or else if the ?x? button has been clicked then the game will exit as well.

  • Automation is not automagic: Why better software automation matters

    Many organizations are trying to create a culture of automation and struggling with what it will take to achieve it—or at least to begin to make a legitimate attempt at creating and maintaining it. This article is a different take on the topic for anyone interested in automation, including people struggling on a team that focuses on automation, a company that hasn't quite figured it out, or teams that aren't returning the expected ROI.

Fedora 30 Workstation review - Smarter, faster and buggier

Fedora 30 is definitely one of the more interesting releases of this family in a long-time. It brings significant changes, including solid improvements in the desktop performance and responsiveness. Over the years, Fedora went from no proprietary stuff whatsoever to slowly acknowledging the modern needs of computing, so now it gives you MP3 codecs and you can install graphics drivers and such. Reasonable looks, plus good functionality across the board. However, there were tons of issues, too. Printing to Samba, video screenshot bug, installer cropped-image slides, package management complications, mouse cursor lag, oopses, average battery life, and inadequate usability out of the box. You need to change the defaults to have a desktop that can be used in a quick, efficient way without remembering a dozen nerdy keyboard shortcuts. All in all, I like the freshness. In general, it would seem the Linux desktop is seeing a cautious revival, and Fedora's definitely a happy player. But there are too many rough edges. Well, we got performance tweaks after so many years, and codecs, we might get window buttons and desktop icons one day back, too. Something like 6/10, and definitely worth exploring. I am happy enough to do two more tests. I will run an in-vivo upgrade on the F29 instance on this same box, and then also test the distro on an old Nvidia-powered laptop, which will showcase both the support for proprietary graphics (didn't work the last time) and performance improvements, if they scale for old hardware, too. That's all for now. Read more

Events: Automotive at LF, Linux Clusters Institute, Linux Plumbers Conference (LPC)

  • Automotive Linux Summit and Open Source Summit Japan Keynote Speakers and Schedule Announced
    The Linux Foundation, the nonprofit organization enabling mass innovation through open source has announced the speaker line up for Open Source Summit Japan and Automotive Linux Summit. One registration provides access to all content at both events, which will be held July 17-19 at the Toranomon Hills Forum in Tokyo. Open Source Summit Japan (OSSJ) and Automotive Linux Summit (ALS) will bring together top talent from companies on the leading edge of innovation including Toyota Motor Corporation, Uber, Intel, Sony, Google, Microsoft and more. Talks will cover a range of topics, with ALS talks on everything from infrastructure and hardware to compliance and security; and OSSJ sessions on AI, Linux systems, cloud infrastructure, cloud native applications, open networking, edge computing, safety and security and open source best practices.
  • Register Now for the 2019 Introductory Linux Clusters Institute Workshop
    Registration is now open for the 2019 Linux Clusters Institute (LCI) Introductory Workshop,which will be held August 19-23, 2019 at the Rutgers University Inn & Conference Center in New Brunswick, NJ. This workshop will cover the fundamentals of setting up and administering a high-performance computing (HPC) cluster and will be led by leading HPC experts.
  • Additional early bird slots available for LPC 2019
    The Linux Plumbers Conference (LPC) registration web site has been showing “sold out” recently because the cap on early bird registrations was reached. We are happy to report that we have reviewed the registration numbers for this year’s conference and were able to open more early bird registration slots. Beyond that, regular registration will open July 1st. Please note that speakers and microconference runners get free passes to LPC, as do some microconference presenters, so that may be another way to attend the conference. Time is running out for new refereed-track and microconference proposals, so visit the CFP page soon. Topics for accepted microconferences are welcome as well.

  • Illumos-Powered OmniOS Gets Updated Against MDS / ZombieLoad Vulnerabilities
    While it was just earlier this month that the OpenSolaris/Illumos-based OmniOS saw a big LTS release, it's already been succeeded by a new release given the recent Intel MDS / Zombieload CPU vulnerabilities coming to light. There are new spins of OmniOS for all supported releases. These new OmniOS Community Edition releases mitigate against the Multiarchitectural Data Sampling (MDS) vulnerabilities and also bundle in the updated Intel CPU microcode.
  • Hackers Hack A Forum For Hacked Accounts: Here’s How
    A group of hackers failed to deploy security mechanisms to secure the storage where they store hacked accounts and another hacker group hacked it. The story is indeed funny and real. Infamous forum named OGUSERS which is popular amongst hackers for obtaining “OG” Instagram, Twitter usernames, hacked accounts of Domino’s Pizza, Steam, PlayStation Network, and other online accounts was hacked by a hacker group and its data was published in another hacker forum.
  • Security Announcement: Disabling SMT by default on affected Intel processors
    This is an important announcement with an upcoming change in the next Core Update of IPFire. Because of the recent vulnerabilities in Intel processors, the IPFire team has decided, that - to keep systems as secure as possible - Simultaneous Multi-Processing (SMT) is automatically disabled if the processor is vulnerable to one of the attacks. SMT is also called Intel(R) Hyper-Threading Technology and simulates more virtual cores than the system has. This allows to perform faster processing when applications benefit from it. Unfortunately with networking, we benefit from that. Therefore the effect of disabling SMT will be a very signifiant performance impact of around 30% or more. Applications that will be affected in IPFire are the firewall throughput itself as well as other CPU and memory-bound tasks like the web proxy and the Intrusion Prevention System. On systems that are not vulnerable for this attack, SMT is being left enabled. If you still want to disable it, please do so in the BIOS of your firewall.
