Tracking Down Blips

V. Anton Spraul's Think Like a Programmer, Python Edition

What is programming? Sure, it consists of syntax and the assembly of code, but it is essentially a means to solve problems. To study programming, then, is to study the art of problem solving, and a new book from V. Anton Spraul, Think Like a Programmer, Python Edition, is a guide to sharpening skills in both spheres. more>>

Manifold Makes Managing Cloud Developer Services Easy

We love it here when superheroes drop their cloak of invisibility, emerge from stealth mode and reveal themselves to the world. Of course we do—it's the geek in us! Manifold has just done exactly that, emerged from stealth mode and is claiming to be the easiest way to find, buy and manage essential developer services. more>>

Sysadmin 101: Leveling Up

This is the fourth in a series of articles on systems administrator fundamentals. These days, DevOps has made even the job title "systems administrator" seems a bit archaic like the "systems analyst" title it replaced. more>>

YouTube on the Big Screen

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. more>>

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.

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.

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>>

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>>

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
