Distributed denial of service attacks, in which hackers use a targeted hose of junk traffic to overwhelm a service or take a server offline, have been a digital menace for decades. But in just the last 18 months, the public picture of DDoS defense has evolved rapidly.

Last week Python, Raspberry Pi, Linux, containers, and Kubernetes dominated our list of reader favorites.

A “Leguino” educational hacker kit launching on Kickstarter lets you extend Lego projects with Lego form-factor gears, motors, displays, sensors, and breadboards, controlled by a “Visuino” GUI dev environment running on an Arduino or RPi Zero W.

If you are a Linux user who is also into system level software development, you may find yourself in situations where-in you need information related to symbols in an object file. You'll be glad to know there exists a command line utility - dubbed nm - that you can use in these situations.

Continuous Integration (CI) is the process of running tests for every change made to a project, integrated as if this were the new deliverable. If done consistently, it means that software is always ready to be released. CI is a very... Continue Reading →

The inexpensive Kodak Brownie was the first camera to bring photography to the masses. The simplicity of its design meant anyone could figure out how to use it with little difficulty. Because it has essentially no controls to learn—there's just a shutter button, viewfinder, and film winder—it's even easy to use in comparison to today's cameras. read more

There has been much hype around the Spectre and Meltdown vulnerabilities that emerged in January, a huge impact in the world of software vulnerabilities. While some of this is justified by the fact that those vulnerabilities affected a majority of all processors in the market, the reality is that this was just another vulnerability on top of all the others in the market, which security professionals need to assess and manage every day.

The role of data has changed. Data is more than a record; it is a form of communication. Data enhances lives. It makes us more efficient in navigation, banking, shopping, and managing our day-to-day lives. Ultimately, the exchange, valuation, and intelligence of data are currency. Beyond storing it, data must be captured, preserved, accessed, and transformed to take advantage of its possibilities. read more

The best way to level up your programming skills is to code more. The second best way is to read others’ code. What better way to do these things than collaborating in open source projects? read more

The mypy utility is a static type checker for Python. It combines the benefits of dynamic typing and static typing. As you may know, the Python programming language is dynamically typed. So what does static type checking for Python mean?

News briefs for March 9, 2018.

Seco announced a rugged, SMARC form-factor “SM-C12” module that runs Linux or Android on an NXP i.MX8M, and offers soldered LPDDR4, eMMC and QSPI flash, plus an optional wireless module and carrier board. Like its ubiquitous i.MX6 system-on-chip, NXP’s new quad-core, Cortex-A53 i.MX8M is so versatile that you can spin it into diverse applications.

One of the reasons I stood up a Kubernetes cluster on Raspberry Pis in my house was because I wanted to gain savings by not running high-available, redundant infrastructure in the cloud. Kubernetes provides high availability by design. The possibilities that this capability offers are pretty awesome. Need a web server to run constantly? Build a container and throw it in the Kubernetes cluster. Need a service available all the time? Package it and ship it to the Kubernetes cluster. read more

Python is easy to use, powerful, versatile and a Linux Journal reader favorite. We've round up some of the most popular recent Python-related articles for your weekend reading.

In your open source adventures, you may have heard the acronyms CLA and DCO, and you may have said "LOL WTF BBQ?!?" These letters stand for Contributor License Agreement and Developer Certificate of Origin, respectively. Both have a similar intent: To say that the contributor is allowed to make the contribution and that the project has the right to distribute it under its license. read more

Linux offers several commands that display in output the current user's login name. One of those is logname. In this tutorial, we will quickly understand the basics of this command line tool using some easy to understand examples.

The amount of geekery and hackage required to bring companies into compliance with the EU's General Data Protection Regulation (aka GDPR) must be huge. I say that for five reasons. Let us know how the GDPR is affecting your work.

I want to highlight three of the more popular “app stores” to be found on various Linux distributions. In the end, you’ll see that installing applications on Linux, regardless of your distribution, doesn’t have to be a nightmare.

At The Linux Foundation's OSLS event in Sonoma this week, CNCF's COO Chris Aniszczyk announced that its Kubernetes project has become a full blown project. Read the rest of this installment of our weekly digest to stay in the know!
