When Linux required installation parties

11 hours 13 min ago

I studied math in college. Back then, ordinarily, math students didn't have access to the computer lab; pen and paper were all we needed to do our work. But for my one required programming class, I got access to the college computer lab.

It was running SunOS with remote X terminals (this was circa 1996). I immediately fell in love with Unix. I fell in love with the command line, X Windows, the utilities—all of it.

Deep learning is gaining tremendous momentum in certain academic and industry circles. Inference—the capability to retrieve information from real-world data based on pre-trained models—is at the core of deep learning applications.

How to get started in AI

11 hours 15 min ago

I've both asked and been asked about the best way to learn more about artificial intelligence (AI). What should I read? What should I watch? I'll get to that. But, first, it's useful to break down this question, given that AI covers a lot of territory.

One important distinction to draw is between the research side of AI and the applied side. Cassie Kozyrkov of Google drew this distinction in a talk at the recent O'Reilly Artificial Intelligence Conference in London, and it's a good one.

Optimizing Kubernetes resource allocation in production

Sunday 9th of December 2018 08:00:00 AM

My first day with Kubernetes involved dockerizing an application and deploying it to a production cluster. I was migrating one of Buffer's highest throughput (and low-risk) endpoints out of a monolithic application. This particular endpoint was causing growing pains and would occasionally impact other, higher priority traffic.

Automatic continuous development and delivery of a hybrid mobile app

Friday 7th of December 2018 08:01:00 AM

Offering a mobile app is essentially a business requirement for organizations today. One of the first steps in developing an app is to understand the different types—native, hybrid (or cross-platform), and web—so you can decide which one will best meet your needs.

Is open source wealth distribution fair?

Friday 7th of December 2018 08:00:00 AM

If wealth is the abundance of valuable possessions, open source has a wealth of software. While no one “owns” open source, some are better than others at converting this communal wealth to personal wealth.

Many open source project maintainers who produce free open source software do not have a model for deriving income from the assets they have created. However, companies that use open source software to enhance their products and services convert this valuable asset into income.

How to view XML files in a web browser

Thursday 6th of December 2018 08:01:00 AM

Once you learn that HTML is a form of XML, you might wonder what would happen if you tried to view an XML file in a browser. The results are quite disappointing—Firefox shows you a banner at the top of the page that says, "This XML file does not appear to have any style information associated with it. The document tree is shown below." The document tree looks like the file would look in an editor:

5 reasons to give Linux for the holidays

Wednesday 5th of December 2018 08:02:00 AM

Every year around this time, people ask me about the best computer to give (or get) for the holidays. I always give the same answer: Linux. After all, if you want your recipients to be happy, why wouldn't you give them the best operating system on the planet?

Many people don't realize they have options when it comes to computer operating systems. Just recently, two friends (who didn't do their research) fell for the clever marketing and bought brand-new systems at premium prices. I'm willing to bet that within six months they'll be dissatisfied with those expensive computers.

Testing Ansible roles with Molecule

Wednesday 5th of December 2018 08:01:00 AM

Test techniques play an important role in software development, and this is no different when we are talking about Infrastructure as Code (IaC).

Developers are always testing, and constant feedback is necessary to drive development. If it takes too long to get feedback on a change, your steps might be too large, making errors hard to spot. Baby steps and fast feedback are the essence of TDD (test-driven development). But how do you apply this approach to the development of ad hoc playbooks or roles?

Blueprint for a team with a DevOps mindset

Wednesday 5th of December 2018 08:00:00 AM

I've had the privilege to work with some of the brightest minds and leaders in my 33 years of software engineering. I've also been fortunate to work for a manager who made me question my career daily and systematically broke down my passion—like a destructive fire sucking the oxygen out of a sealed space. It was an unnerving period, but once I broke free, I realized I had the opportunity to reflect on one of the greatest anti-patterns for effective teams.

Essential System Tools: Timeshift – Reliable system restore tool for Linux

This is the twelfth in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For this article, we’ll look at Timeshift, a graphical and command-line tool similar to the System Restore functionality offered by Windows, and the Time Machine Tool in Mac OS. For details of all tools in this series, please check the table at the summary page of this article. Timeshift is a GTK3-based, open source, system restore utility which takes incremental snapshots of the system using rsync and hard-links. These snapshots can be restored at a later date to undo all changes that were made to the system after the snapshot was taken. Snapshots can be taken manually or at regular intervals using scheduled jobs. This application is designed to protect only system files and settings. User files such as documents, pictures and music are not protected. This ensures that your files remains unchanged when you restore your system to an earlier date. For the avoidance of any doubt, if you’re looking for a complete backup solution (including data backups), you’ll need to use different software. Read more
