Meltdown & Spectre --update--

Yeah, sometimes it does not warrant any extra security to be cutting edge... This I know.

That a hardware-vulnerability has gone unchecked for a couple of decades, however, eluded even me. Even more that it wasn't even addressed / announced before very recently.

Turns out, almost every computing-device I own has these bugs. And I find myself in a situation where I do as very many others do with vulnerable equipment, with little to no chance of patching; I just isolate them.

Don't get me wrong, I've taken measures and patched / disabled low-level functions as best I could. But when the issue is basically invisible (ring -3), there's limits to what I can do to fix it.

The ass-hats who made the shit have to fix it properly, or someone considerably smarter than me have to do what they can to mitigate as the circumstances will allow.

Which, from what I understand isn't much, and it's massively complicated to boot. The complications are the reasons for the "considerable performance slow-down" that will result from the software-fixes to the issue.


Seems these bugs / vulnerabilities have been blown totally out of proportion for the average computer-user.

Slowdowns only present themselves at huge workloads (think Big Data databases, enterprise computing, etc.), so average-Joe won't even notice any difference... I've been pretty buzy patching / fixing my affected systems lately, both at work and at home, and I can't say I've noticed any significant slowdowns in any way.

Not that I've got huge workloads, or global-spanning database-queries running 24/7, but I've definitely got bigger and heavier workloads than the average man.

--- If people just patch their systems regularly, they'll be fine ---

Desktop-Linux + CLI?

"If there's one thing surrounding Linux usage that bothers me more than anything else, it's when the detractors say you cannot work with Linux without knowing the command line. This is a bit of FUD — fear, uncertainty, and doubt — that keeps new users from giving the open source platform a try. I'm here, right now, to dispel that myth."
Ubuntu Desktop
Linux Mint (MATE edition)

With personal experience, I can attest to this statement. The days when you HAD to deal with the Command Line even on desktop-Linux distros are past. Only server-distros demand this nowadays.

To my doubters

Yes, seems I finally landed my dream-job =D It's not work, it's fun :)

I get to work with innovating and bleeding-edge technology every day, at my own terms, with all the tech-benefits I could wish for. Not to mention my contract-benefits, and office-benefits (sponsored gourmet coffee, UV-filtered water and Red Bull).

"Red Bull-fridge"

Working with as smart people as I do is, well, very rewarding in itself. Finally, people at my own level! People who actually appreciates open-source and Linux!

To all my doubters and nay-sayers:
how's that Microsoft-programming job working out for you?

Cloud Engineer + DevOps

The Cloud

A cloud engineer is an IT professional responsible for any technological duties associated with cloud computing, including design, planning, management, maintenance and support.

The cloud engineer position can be broken into multiple roles, including cloud architect, cloud software engineer, cloud security engineer, cloud systems engineer and cloud network engineer.

Each position focuses on a specific type of cloud computing, rather than the technology as a whole. Companies that hire cloud engineers are often looking to deploy cloud services or further their cloud understanding and technology.



DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.

From my employer's website [edit/red.]:
 Robots and artificial intelligence create opportunities of enormous dimensions. 

 We have developed the market-leading virtual assistant, who has taken the European market by storm. The company is experiencing rapid growth and we are looking for new colleagues to join us at our office in Stavanger, Norway. Become a part of what the World Economic Forum calls "The Fourth Industrial Revolution"! 

 As an employee in our company, you become a part of a young and dynamic environment with a high degree of freedom for self-development. Your colleagues have exceptional expertise in data and technology, and all developers get access to state of the art equipment. 

 Our technology stack today consists of Linux, PostgreSQL, Apache, Varnish, Java, Spring, Grails, Groovy, Gradle, Python, Javascript, Lua, Torch, IntelliJ IDEA, Git and Amazon Web Services (hence the aws-amazon links above). We will use any required additional technologies in the future to solve whatever new challenges may arise.

In 2017, Linux rules computing

 The Linux Foundation reports that Linux runs 90 percent of the public cloud workload, 82 percent of the world's smartphones, 62 percent of the embedded market, oh and a mere 99 percent of the supercomputer market. All that rests on the Linux kernel.

"The Linux kernel is one of the largest and most successful open-source projects that has ever come about. The huge rate of change and number of individual contributors show that it has a vibrant and active community, constantly causing the evolution of the kernel in response to number of different environments it is used in. This rate of change continues to increase, as does the number of developers and companies involved in the process; thus far, the development process has proved that it is able to scale up to higher speeds without trouble."

 Good news :)

Over the past year, the kernel has been updated through merged changesets, new drivers, hardening and testing.
