NPM update changes critical Linux filesystem permissions, breaks everything – Naked Security
For example, JavaScript programs in your browser generally can’t reach out into other tabs, can’t start or stop other programs, can’t access files on your hard disk, can’t read the registry, can’t scan the network, can’t sniff around in memory.

Unlike browser JavaScript, Node.js is augmented by add-on toolkits to do just about anything you can think of: manage processes, run servers, read local files and databases, control the network, perform cryptographic calculations, transcode images and videos, recognise faces, you name it.

You may find you can write a five-line JavaScript program that is elegantly simple, but only if your Node Package Manager drags in tens or even hundreds of thousands of lines of other people’s software.

Automatically. From all over the internet.

I found that a selection of directories in / were owned by a non-root user after running sudo npm and many binaries in /usr/bin stopped working as their permissions were changed. People experiencing this bug will likely have to fully reinstall their system due to this update.

Keep backups that make a meaningful rollback easy. NPM has caused reliability disasters before, and given its vaguely anarchical nature, will cause them again.
Skip the 5.7.0 version of NPM. NPM version 5.7.1 is supposed to fix this bug.
Don’t autoupdate production or development servers. Prove the latest update in testing first.
Remember that simple software can be immensely complex. Keep that in mind when making time for testing (see 3).

How To Set Up A Cisco Lab On Linux (CentOS 5.2)
After a quick search I found the wonderful Dynamips project that goes beyond what other simulators do by running actual Cisco IOS images, as well as the PEMU project which allows for running of Cisco PIX images. To integrate the various pieces of software and provide an interface for interaction with the devices I used dynagen.

Capturing Packets in Linux at a Speed of Millions of Packets per Second without Using Third Party Libraries
deal with memory allocation by means of RX_RING.
Yay! We’ve got 4 MPPS!!!
Now, run FANOUT mode for version RX_RING!

Hurray! HIGH SCORE!!! 9 MPPS!!!

There’s hope that the nearest versions of the kernel will let us process 10GE at a full wire-speed of 14.6 million packets per second using a 1800 MHz processor :)

No-Cost RHEL Developer Subscription now available - RHD Blog
Containers, microservices, and cloud. Oh my.
If you’re working on, or starting to look at, Linux containers (aka Docker) for cloud-native applications and/or microservices, this new offering means you now have access to the Red Hat Container Development Kit (CDK), a collection of container development tools and resources. The CDK uses a different install process that utilizes Vagrant (and Vagrant boxes), so users will have access to Red Hat Enterprise Linux Server as well as a local desktop instance of OpenShift Enterprise 3 for development use.

Meltdown and Spectre
Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware bugs allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents.

Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. Depending on the cloud provider's infrastructure, it might be possible to steal data from other customers.

U.S. government, military to get secure Android phones - CNN.com
However, the government chose to work on Android first because Google already allows people to tinker freely with its code, said those working on the project. Federal officials have met with Apple, but they were told they could not have access to the core of the company's mobile operating system, said Angelos Stavrou, an information-security director at George Mason University who is working on the government project as a contractor, in a phone interview.

The NSA is also working on a competing system called SE Android, or Security Enhanced Android, Stephen Smalley, a National Security Agency official, wrote this month in a brief e-mail to a group of software developers that was obtained by CNN. SE Android is less flexible in supporting new devices or Android updates from Google and is unlikely to be deployed widely, Stavrou said.

Bringing Android to military communications devices - Military Embedded Systems
Military 'Droid

The rich functionality of the latest multimedia software packages, such as Android, can now be incorporated into even the most demanding real-time, secure military communications devices without increasing hardware footprint, cost, or certification burden. The key innovation is MILS virtualization, which exploits the resource management capabilities, native applications environment, and assurance pedigree of a trusted separation kernel and modern hypervisor techniques to effectively consolidate general-purpose and critical subsystems.

"printer on fire" message history -- 'Re: 2.4.19: drivers/usb/printer.c usblpX on fire' - MARC
The paper jam usually set off the "check" signal and the host would stop sending data to the printer, and report some message to the operator. Sometimes, the offline switch would also be triggered, which (at least in the printer) would stop the drum from spinning. The offline switch was actually triggered by a different condition. I think it was when the paper was no longer in contact with an "out of paper" sensor. If the offline switch wasn't triggered, the drum would continue spinning, and continue adding more heat. The old lpd on UNIX v 6/7 used the check signal to report a "printer on fire" if the offline signal was NOT present. I believe it was the combination of offline and check signal that was used to generate the "out of paper" message.

How to split large file into several smaller files – Linux - Techie Corner
be sure to compare/md5 to verify.
$ split –bytes=1m /path/to/large/file /path/to/output/file/prefix Done. You just split your large file into several smaller files * You can change the output file size by changing the –bytes=1m to your preference. You can use b, k, or m. b represent bytes, k represent kilobytes, m represent megabytes. To restore the original file, you can use cat command. To join all the smaller file to restore $ cat prefix* > NEWFILENAME

Shapir-Worf Hypothesis - Log management - Windows vs. Linux - O'Reilly ONLamp Blog
This reminds me of the Shapir-Worf Hypothesis, which I learned in an anthropology class at LSU a long, long time ago. Essentially, Shapir-Worf says that the language you think in has a very big impact on how you think. A tad simplistic, but it makes sense to some extent.
