  • Top 5 options for Linux certifications

    Linux certifications present an interesting mix of distribution- and brand-agnostic credentials, as well as vendor-specific ones. Many of these offerings provide data center professionals with defined pathways to learn, use and master Linux OS management, features and potential Linux use cases.

    Other programs are more ad hoc and specific to certain IT roles, such as systems engineers or IT administrators, but they go beyond self-taught curriculums and forums. Each program includes coursework and an exam. Depending on the certification, admins can buy everything as a bundle or pay separately for study materials and exams.

  • SimpleMailQt v2.0.0-beta1

    On my last post I talked about the new async simplemail-qt API that I wanted to add, yesterday I finished the work required to have that.

    SMTP (Simple Mail Transfer Protocol) as the name says it’s a very simple but strict protocol, you send a command and MUST wait for the reply, which is rather inefficient but it’s the way it is, having it async means I don’t need an extra thread (+some locking) just to send an email, no more GUI freezes or an HTTP server that is stalled.

    The new Server class has a state machine that knows what reply we are waiting, and which status code is the successful one. Modern SMTP servers have PIPELING support, but it’s rather different from HTTP PIPELING, because you still have to wait for several commands before you send another command, in fact it only allows you to send the FROM the RECIPIENTS email list and DATA commands at once, parse each reply and then send the mail data, if you send the email data before you are allowed by the DATA command the server will just close the connection.

  • Plasma 5 for Slackware – November ktown release

    Dear all, today I released KDE-5_19.11 and it comes with some upgrades to official Slackware packages. Don’t worry – Pat Volkerding kindly added the shared libraries of the official Slackware packages to aaa_elflibs, so if you have been updating your Slackware-current installation properly then nothing will break when you update Slackware’s exiv2 and LibRaw packages to the newer versions contained in the November release of ‘ktown‘.
    Official Slackware package updates for exiv2 and LibRaw will come sometime soon, but it will require Pat to recompile several other packages as well that depend on exiv2 and/or LibRaw. I needed the new exiv2 to compile the latest digikam, so I was pleased with Pat’s cooperation to make this a smooth ‘ktown‘ upgrade for you.

  • Vulnerability Values Fluctuate Between White, Grey and Black Hats

    A black hat selling vulnerabilities can make as much money as a white hat researcher using bug bounty programs, or a grey hat working for a nation state doing reverse engineering.

    Speaking at a Tenable conference in London last week, director of research Oliver Rochford said that to have people do vulnerability research is expensive, and all of the white, black and grey markets are symbiotic, as despite the difference between being legal and illegal, the different factors “mirror each other as it starts with vulnerability discovery.”

    Rochford said that this “shows how professional cybercrime has become,” pointing to the fact that the main difference between criminal and legal sides are ethics. In one slide, Rochford pointed out vulnerability discovery, exploit research and development are the same for both offense and defensive sides, while the differences fall at the "operationalization" side, where offensive sides look at espionage, sabotage and fraud, while defense sides look at threat intelligence and compensating control adaptation.

    In his research, Rochford showed that in some cases you can earn more as a white hat vulnerability manager than as a black hat, with a black hat able to earn around $75,000 in this sort of work. Rochford said this “is achievable and attractive” and while it was more lucrative to do it legally, if it is not “it is a way to make a living.”

Linux Foundation: ACT Program, Dent and Delta Lake

  • Amazon is joining a project that could upend network chipmakers such as Broadcom

    Amazon is contributing to a new piece of open-source software that could give it a leg up in its physical stores. The Linux Foundation, a nonprofit organization that maintains the Linux operating system and open-source software, announced the new networking operating system, called Dent, in a statement on Friday. Dent is a proposed operating system for switches, which are pieces of hardware used to route data around networks, usually within companies or between companies and the internet. The market has traditionally been dominated by big companies such as Broadcom, which provides a lot of the underlying silicon chips, and Cisco, which sells finished assembled product.

  • Calmer waters promised in the data lake through Linux Foundation Delta Lake Project

    Delta Lake (wait for it… the clue is in the name) is a project focusing on improving the reliability and performance of data lakes. Delta Lake was actually announced by unified analytics company Databricks earlier this year before this autumn becoming a Linux Foundation project with an open governance model. The team points out that organisations in every vertical aspire to get more value from data through data science, machine learning and analytics, but they are hindered by the lack of data reliability within data lakes.

Programming/Admin: Rootconf, Awk, UNIX, Wireguard and Python

  • Rootconf Hyderbad, 2019

    Rootconf is the conference on sysadmins, DevOps, SRE, Network engineers. Rootconf started its journey in 2012 in Bangalore, 2019 was the 7th edition of Rootconf. In these years, through all the Rootconfs, there is a community that has developed around Rootconf. Now people do come to attend Rootconf not just to attend the conference but also to attend friends and peers to discuss projects and ideas.

  • A bit of fun with awk

    I learned a few tidbits in awk this week. awk is a language I have, at best, looked at only very superficially, even though I use it frequently if very basically: to chop a line into fields. I tend to use it more than cut(1) because I can print additional data to that which I’ve cut out (without having to add sed(1) so awk just is more versatile for me.

  • How Unix Works: Become a Better Software Engineer

    I’ll put just enough commands for us to play along, assuming you’re starting from scratch. We’ll explore concepts, see them in practice in a shell, and then scream “I GET THIS!”. Along the way, we’ll also figure out what a shell really is.

    But we can’t begin without getting into the minds of the creators: exploring Unix’s philosophy.

    For now, we can assume Linux is Unix. If you want to know why that’s not really the case, you can skip to the bottom and come back. We’ll end the Unix vs linux confusion once and for all.

  • wireguard

    wireguard (wg) is a modern vpn protocol, using the latest class of encryption algorithms while at the same time promising speed and a small code base.

    modern crypto and lean code are also tenants of openbsd, thus it was a no brainer to migrate my router from openvpn over to wireguard.

  • Python Software Foundation: Mozilla and Chan Zuckerberg Initiative are funding pip with $407,000

    The Mozilla Corporation and the Chan Zuckerberg Initiative are funding the Python package installer pip with $407,000 USD to support work that is planned for 2020. Where is pip headed next year? The roadmap has been laid out, so let’s have a look at what the future holds. As the Python Software Foundation (PSF) announced in a blog post, it is receiving $207,000 USD from Mozilla via the Mozilla Open Source Support Award and $200,000 USD from the Chan Zuckerberg Initiative (CZI) as Essential Open Source Software for Science grant. The funds are designated to support a three-phased working plan for pip in 2020 to make the package installer “easier for people to use and troubleshoot”, and here’s what’s going to happen.

  • A Tiny Python Exception Oddity

    If you go back to the first case I discussed, with the unmatched parenthesis, in Friendly-traceback, I rely on the location of the error shown by Python to indicate where the problem arose and, when appropriate, I look *back* to also show where the potential problem started. Unfortunately, I cannot do that in this case with CPython.
