Drupal shows leadership on diversity and inclusion

9 hours 48 min ago

I didn't expect DrupalCon Seattle's opening keynote to address the barriers that hold people back from making open source contributions. So imagine my surprise when Dries Buytaert, Drupal's project lead and co-founder and CTO of Acquia, which created Drupal, used his time onstage to share an apology.

Why I use rxvt as my terminal

Tuesday 15th of October 2019 07:02:00 AM

I'm a fan of Konsole and GNOME Terminal, and I use them both regularly. They're great projects, and they represent modern terminals that meet the needs of users who spend their day in a shell, as well as users who only dip into a Unix shell every now and again. They integrate nicely into a desktop environment, bridging the gap between common GUI tasks and common shell tasks. I use GNOME Terminal at work and Konsole at home, and I enjoy them both.

Formatting NFL data for doing data science with Python

Tuesday 15th of October 2019 07:01:00 AM

No matter what medium of content you consume these days (podcasts, articles, tweets, etc.), you'll probably come across some reference to data. Whether it's to back up a talking point or put a meta-view on how data is everywhere, data and its analysis are in high demand.

As a programmer, I've found data science to be more comparable to wizardry than an exact science. I've coveted the ability to get ahold of raw data and glean something useful and concrete from it. What a useful talent!

How GNOME uses Git

Tuesday 15th of October 2019 07:00:00 AM

“What’s your GitLab?” is one of the first questions I was asked on my first day working for the GNOME Foundation—the nonprofit that supports GNOME projects, including the desktop environment, GTK, and GStreamer. The person was referring to my username on GNOME’s GitLab instance.

How to make a Halloween lantern with Inkscape

Monday 14th of October 2019 07:03:00 AM

The spooky season is almost here! This year, decorate your haunt with a unique Halloween lantern made with open source!

Typically, a portion of a lantern's structure is opaque to block the light from within. What makes a lantern a lantern are the parts that are missing: windows cut from the structure so that light can escape. While it's impractical for lighting, a lantern with windows in spooky shapes and lurking silhouettes can be atmospheric and a lot of fun to create.

My Linux story: I grew up on PC Magazine not candy

Monday 14th of October 2019 07:01:00 AM

In 1998, the movie Titanic was released, mobile phones were just a luxury, and pagers were still in use. This was also the year I got my first computer. I can remember the details as if it were yesterday: Pentium 133MHz and just 16MB of memory. Back in that time (while running nothing less than Windows 95), this was a good machine. I can still hear in my mind the old spinning hard drive noise when I powered that computer on, and see the Windows 95 flag.

Pros and cons of event-driven security

Monday 14th of October 2019 07:00:00 AM

Great news, everyone! Forrester Research says that 95% of all recorded breaches in 2016 came from only three industries: government, technology, and retail. Everyone else is safe... ish, right?

Everything you need to know about Grace Hopper in six books

Friday 11th of October 2019 07:02:00 AM

Grace Hopper is one of those iconic figures that really needs no introduction. During her long career in the United States Navy, she was a key figure in the early days of modern computing. If you have been involved in open source or technology in general, chances are you have already heard several anecdotes about Grace Hopper. The story of finding the first computer bug, perhaps? Or maybe you have heard some of her nicknames: Queen of Code, Amazing Grace, or Grandma COBOL?

DevSecOps pipelines and tools: What you need to know

Thursday 10th of October 2019 07:01:00 AM

DevOps is well-understood in the IT world by now, but it's not flawless. Imagine you have implemented all of the DevOps engineering practices in modern application delivery for a project. You've reached the end of the development pipeline—but a penetration testing team (internal or external) has detected a security flaw and come up with a report. Now you have to re-initiate all of your processes and ask developers to fix the flaw.

Climate challenges call for open solutions

Thursday 10th of October 2019 07:00:00 AM

Global climate change affects us all. It is, at its heart, an energy issue—a problem too large and too complex for any single person, company, university, research institute, science laboratory, nuclear trade association, or government to address alone. It will require a truly global, cooperative effort, one aimed at continued innovation across a range of technologies: renewables, batteries, carbon capture, nuclear power development, and more.

Start developing in the cloud with Eclipse Che IDE

Wednesday 9th of October 2019 07:02:00 AM

In the many, many technical interviews I've gone through in my professional career, I've noticed that I'm rarely asked questions that have definitive answers. Most of the time, I'm asked open-ended questions that do not have an absolutely correct answer but evaluate my prior experiences and how well I can explain things.

One interesting open-ended question that I've been asked several times is:

"As you start your first day on a project, what five tools do you install first and why?"

How to use clipboard managers on Linux

Wednesday 9th of October 2019 07:01:00 AM

You probably copy and paste snippets of text on your computer multiple times a day without ever thinking about it. You may take it for granted, because it's older than Unix, with its earliest implementation through macros or manual repetition of line-editor commands. While the process has largely remained the same over the past 15 years, there's a side to copy and paste that many users never see: the clipboard manager.

Why to choose Rust as your next programming language

Wednesday 9th of October 2019 07:00:00 AM

Choosing a programming language for a project is often a complicated decision, particularly when it involves switching from one language to another. For many programmers, it is not only a technical exercise but also a deeply emotional one. The lack of known or measurable criteria for picking a language often means the choice digresses into a series of emotional appeals.

VirtualBox Adds Support for Linux Kernel 5.3, Red Hat Enterprise Linux 8.1 Beta

VirtualBox 6.0.14 is here to add support for new technologies, fix bug, and add various improvements. For example it implements support for the Linux 5.3 kernel series, as well as for the Red Hat Enterprise Linux 7.7, CentOS Linux 7.7, Oracle Linux 7.7m and Red Hat Enterprise Linux 8.1 Beta operating systems. On top of that, VirtualBox 6.0.14 improves the detection of the Python version during the creation of the RPM package on Linux hosts to address some installation issues addresses and package dependencies, and improves shared folders for Linux guests, especially when unmounting them in service script.

Fedora at 15: Why Matthew Miller sees a bright future for the Linux distribution

Fedora—as a Linux distribution—will celebrate the 15th anniversary of its first release in November, though its technical lineage is much older, as Fedora Core 1 was created following the discontinuation of Red Hat Linux 9 in favor of Red Hat Enterprise Linux (RHEL). That was a turbulent time in Red Hat history, and Fedora has had its own share of turbulence as well. Since becoming project leader in June 2014, Matthew Miller had led the Fedora.next initiative, intended to guide the second decade of the Fedora project. That initiative resulted in the creation of separate Fedora Workstation, Server, and Cloud editions—the latter of which has since been replaced with CoreOS—as well as the addition of an Internet of Things (IoT) edition.

Some nice widgets for your Plasma desktop

Plasma is an extremely extensible, flexible desktop environment, and it lets you customize and change anything and everything to the tiniest detail. You can go about mimicking other desktops and systems as you please, limited only by your imagination and patience. If you want a Mac-like look or a Unity look, you can. So I thought, I should revisit my old Plasma widgets article and explore some fresh applets out there, to see what else you can do here. Indeed, there are lots of hidden goodies lurking beneath the surface, and if you're curious, you will discover fresh tools and features that can make the Plasma desktop experience even more enjoyable.

  • Cybersecurity Awareness Month: Increasing our self-awareness so we can improve security

    October has been National Cybersecurity Awareness Month since 2004. According to staysafeonline.org, this initiative was started by the National Cybersecurity Alliance and the US Department of Homeland Security to help all Americans stay safe and secure when online. This month is usually marked with a significant uptick in cybersecurity outreach and training. It’s also the one month of the year when you can get a significant amount of cybersecurity swag such as webcam covers, mugs, and pens. This event has an outward focus to raise awareness of security globally, Many other events have come into existence along with this. For example, there are numerous electronics recycling events that now occur in October where people can securely dispose of their old computers. Some municipalities have extended this to include safe disposal of old prescription medications, paints, and other hazardous materials. Recent events in the greater technology community, specifically the resignation of Richard Stallman from both MIT and the Free Software Foundation, have become character foils that show us that while we have come a long way, we still have a long way ahead of us to improve.

  • Michael Tremer/IPFire: On quadrupling throughput of our Quality of Service

    There have been improvements to our Quality of Service (or QoS) which have made me very excited. Our QoS sometimes was a bottleneck. Enabling it could cut your bandwidth in half if you were unlucky. That normally was not a problem for larger users of IPFire, because if you are running a 1 Gigabit/s connection, you would not need any QoS in the first place, or your hardware was fast enough to handle the extra load. For the smaller users this was, however, becoming more and more of a problem. Smaller systems like the IPFire Mini Appliance are designed to be small (the clue is in the name) and to be very energy-efficient. And they are. They are popular with users with a standard DSL connection of up to 100 Megabit/s which is very common in Germany. You have nothing to worry about here. But if you are lucky to have a faster Internet connection, then this hardware and others that we have sold before might be running out of steam. There is only so much you can get out of them.

  • The City Of Baltimore Blew Off A $76,000 Ransomware Demand Only To Find Out A Bunch Of Its Data Had Never Been Backed Up [Ed: Windows]

    The City of Baltimore was hit with a ransomware attack in May of this year. Criminals using remodeled and rebranded NSA exploits (EternalBlue) knocked out a "majority" of the city's servers and crippled many of its applications. More details didn't surface until September when the city's government began reshuffling the budget to cover the expenses of recovering from the attack.
