Kubernetes is King in Container Survey

Apr 13 8:00am
Kubernetes is in, container registries are a dime a dozen, and maximum container density isn't the only thing that matters when running containers. Those are some of the insights gleaned by Sysdig, maker of on-prem and in-cloud monitoring solutions, from customers for how they're using containers in 2017. Using a snapshot of Sysdig's services that encompassed 45,000 running containers, Sysdig's 2017 Docker Usage Report shows that container adoption is getting diversified by workload, and it covers some of the hot-or-not aspects of the new container stack.

Review: Manjaro Linux 17.0.1 "Gellivara" Xfce

Apr 12 8:09am Das U-Blog by Prashanth
This is the next installment of my series of reviews to determine which Linux distribution I can use to replace my current installation of Linux Mint 13 LTS "Maya" Xfce on my personal laptop. The (not strict) criteria that I am considering are that the distributions should be well-known, which is reflected to some degree in DistroWatch rankings, as this implies that the distribution may have official or strong community support for popular proprietary packages; additionally, the distributions I consider should preferably have MATE or Xfce editions (though I'm open to other DEs as well), and should have a long (more than 3 years from now) support cycle or use a rolling-release support model.Main Screen + Xfce Whisker MenuThe current distribution I am trying is the latest Xfce edition of Manjaro Linux. It is a rolling-release distribution that was formerly based on Arch Linux, though it still uses the Arch User Repositories (AUR) for many packages that the distribution maintainers do not officially test. It also has an official KDE edition, as well as community-supported editions for other DEs. I tested the 64-bit version (though a 32-bit version is available too) on a live USB made through the "dd" command. (This time, I used a USB stick that I have never used before, to avoid the issues seen in my recent review of openSUSE with my previous aging USB stick that I have been using for reviews for the last 8 years.)

Book Review: "Atomic Accidents" by James Mahaffey

Apr 10 8:12am Das U-Blog by Prashanth
I've recently read Atomic Accidents by James Mahaffey. It's a fairly long and detailed exposition into accidents involving civilian nuclear power or military nuclear weapons in the US, UK, [former] USSR, Japan, and elsewhere. The author goes into quite granular detail with respect to the history of a certain weapon or civilian site, the timeline of the accident, and the aftermath; with each, he summarizes the lessons that were learned (or should have been learned but were not). After an introduction showing how nuclear accidents are quite similar in many respect to railroad accidents, the first few chapters go into the development of nuclear technology through WWII and the accidents along the way. The middle section of the book goes into knowledge gained about the occupational hazards of employees at power plants, the risks of transporting nuclear material by airplane, and related ideas. The last few chapters are about more recent accidents in Three Mile Island, Chernobyl, and Fukushima, ending with an assessment of the current state of nuclear power.As a layperson with respect to the field of nuclear engineering, I think this book may be best suited for experts and other people with a serious interest in the field; for laypeople, the first few and last chapters are interesting, but reading through the middle sections became somewhat tiresome, as the technical details and jargon were a bit hard to follow, and the structure of the stories of the accidents became rather repetitive. The author does discuss issues of fear/hysteria in the general public with respect to nuclear accidents, yet the [seemingly contradictory] combination of the overall discussion of nuclear accidents in gritty detail along with some relatively cursory words of support for the safety and efficacy of nuclear power at the end means that this really is for experts who rationally understand the full historical & current contexts underlying nuclear power. Additionally, as a side note, the author briefly mentions India's nuclear program twice, noting that the Indian government broke a promise to Canada to not turn an imported reactor design toward weapons development, and that nuclear power plants there have had spotty safety records; while I am all for calling out entities that are cavalier about these issues, I found the author's word choice to be unnecessarily condescending toward Ind...

The Root Cause of Input-Based Security Vulnerabilities Dont Fear the Grammar

Input-based attacks like Buffer Overflows, Cross-Site Scripting (XSS), and XXE are common in today’s software. And they do not go away. But why is that?

In this post I wrap up some ideas of Language Security Langsec which find a general solution to this problem and provide some tools to fix it.

5 Reasons Node.js Rules for Complex Integrations

Anyone who has integrated an application into Slack, for example, will have been treated to an incredibly smooth experience. In many cases it’s as simple as filling in a form (a URL or two, an authentication key) and hitting the Submit button. That’s plain awesome.
