Speeding Up Netfilter (by Avoiding Netfilter)

Imre Palik tried to speed up some of Linux's networking code but was met with stubborn opposition. Essentially, he wanted networking packets to bypass the netfilter code unless absolutely necessary. Netfilter, he said, was designed for flexibility at the expense of speed. According to his tests, bypassing it could speed up the system by as much as 15%.

Everything You Need to Know about the Cloud and Cloud Computing, Part II: Using the Cloud

How to get started with AWS, install Apache, create an EFS volume and much more. The cloud is here to stay, regardless of how you access data day to day. Whether you are uploading and sharing new photos with friends in your social-media account or updating documents and spreadsheets alongside your peers in your office or school, chances are you're connecting to the cloud in some form or another.

After putting this question to the experts, the conclusion is that no matter what you call it, it's still Linux at its core. Should the Linux operating system be called "Linux" or "GNU/Linux"? These days, asking that question might get as many blank stares returned as asking, "Is it live or is it Memorex?"

Read-Only Memory

Igor Stoppa posted a patch to allow kernel memory pools to be made read-only. Memory pools are a standard way to group memory allocations in Linux so their time cost is more predictable. With Igor's patch, once a memory pool was made read-only, it could not be made read-write again. This would secure the data for good and against attackers. Of course, you could free the memory and destroy the pool. But short of that, the data would stay read-only.

The Road Less Traveled: Certifications Can Chart a Great Career in Linux and Open Source

Taz Brown writes about the challenges of a career in IT and her goals of helping to increase diversity in the field and bring Linux to urban education. The year is now 2018, and the world has changed tremendously in so many ways. One thing that's changed significantly is the way we learn and the way we demonstrate that knowledge. No longer is a college degree enough, particularly in the area of Information Technology (IT). Speak to two technologists about how they paved their way in the field, and you will get, oftentimes, completely different stories.
