For years I've been jealous of folks with iOS devices who could just send their phone screens to their Apple TV devices. It seems like the Android screen-mirroring protocols never work right for me. My Sony Xperia has multiple types of screen mirroring, and none of them seem to work on my smart TVs or Roku devices.

Key Considerations for Software Updates for Embedded Linux and IoT

The Mirai botnet attack that enslaved poorly secured connected embedded devices is yet another tangible example of the importance of security before bringing your embedded devices online. A new strain of Mirai has caused network outages to about a million Deutsche Telekom customers due to poorly secured routers. more>>

Paragon Software Group's Paragon ExtFS for Mac

Ever more Mac aficionados are discovering the virtues of Linux, especially when their older hardware can experience a renaissance. One annoying barrier to dual-boot nirvana is filesystem incompatibility, whereby the Linux side can access the Mac side, but Apple's macOS doesn't support Linux drives at all—not even in read-only mode. more>>

Caldwell Partners' Cyber Advisory Board Service

For many enterprises, cyber risk is the top business risk. Meanwhile, there is simply not a sufficiently large talent pool of cyber-risk professionals to satisfy the ever-growing demand. more>>

Solving Physics Problems on Linux

Several years ago, I wrote an article on using Elmer to solve complicated physics problems. Elmer has progressed quite a bit since then, so I thought it would be worth taking a fresh look at this simulation software. more>>

I'll Gladly Pay You Tuesday for a Hamburger Today

My day job pays me on the 15th and last day of every month, unless those days land on a weekend, in which case I get paid the Friday before. With those rules, creating a Google Calendar event is shockingly difficult. In fact, it's not possible to create a recurring event with those rules using Google's GUI scheduling tool. more>>

Watermarking Images--from the Command Line

Us geeks mostly think of the command line as the best place for text manipulation. It's a natural with cat, grep and shell scripts. But although you can't necessarily view your results from within a typical terminal window, it turns out to be pretty darn easy to analyze and manipulate images from within a shell script. more>>

Chasing Carrots' Pressure Overdrive

A "funky, four-wheeled shoot 'em up" is how independent game-developer Chasing Carrots describes its newest game release Pressure Overdrive for Linux, Mac OS, Windows and Xbox. more>>

Non-Linux FOSS: Mac2Imgur

I love to share images with people quickly. They could be cat photos or screenshots. Usually I post those silly images to Twitter and Facebook using Buffer, but occasionally, I just want to send a quick image to a single person. (This is usually when I'm trying to show my computer via screenshot.) more>>

Heirloom Software: the Past as Adventure

Through the years, I've spent what might seem to some people an inordinate amount of time cleaning up and preserving ancient software. My Retrocomputing Museum page archives any number of computer languages and games that might seem utterly obsolete. more>>

SUSE Linux Enterprise Server for SAP Applications

Saving customers time, effort and budget as they implement SAP landscapes, including on-premises and now on-demand, are the core selling points for SUSE Linux Enterprise Server for SAP Applications.

The latest release of the SAP-focused SUSE Linux server is also now available as the operating system for SAP solutions on Google Cloud Platform (GCP). more>>

Classifying Text

In my last few articles, I've looked at several ways one can apply machine learning, both supervised and unsupervised. This time, I want to bring your attention to a surprisingly simple—but powerful and widespread—use of machine learning, namely document classification. more>>

Linux Journal September 2017

Soup to Nuts

One of my favorite things about Linux is that it has become not only the platform of choice for many projects, but it also tends to inspire an entire ecosystem of open-sourc more>>

If Not This Then Stringify

I love IFTTT (If This Then That), but although it usually works well, it's more and more common for triggers to fail. Sometimes they don't fail, but take several minutes to activate. When you want a light to turn on as you enter a room, several minutes of delay clearly can be a deal-breaker. more>>

Ocado Technology's Kubermesh

Instead of relying on servers concentrated in one large data center, the new Kubermesh is designed to simplify data-center architectures for smart factories by elegantly and cost effectively leveraging a distributed network of computing nodes spread across the enterprise. more>>

Sysadmin 101: Ticketing

This is the third in a series of articles on system administrator fundamentals where I focus on some lessons I've learned through the years that might be obvious to longtime sysadmins, but news to someone just coming into this position. more>>
