A twitter call to say nice things about technology sparked interesting threads

Posted by jpluimers on 2022/05/27

A while ago [Archive.is] Adam Jacob on Twitter: “Let’s say nice things about technology today. I’ll start. If it wasn’t for @lkanies and @puppetize, there is no way we would have been able to adapt as an industry to the rise of the cloud. Quote tweet me with your own.” sparked some interesting threads.

First posts are below; click on them to see the full threads.

Need to revisit osquery: SQL powered operating system instrumentation, monitoring, and analytics supports more platforms and also aggregates to central log locations

Posted by jpluimers on 2022/01/18

Almost two years ago, GitHub – facebook/osquery: SQL powered operating system instrumentation, monitoring, and analytics published from the automatic blog queue.

It was in the midst of my rectum cancer treatment, so I was glad the blog queue back then was still about 18 months deep.

This meant I looked into osquery in 2018, which I remember because I needed it on MacOS as I did not want to remember the syntax for MacOS specific commands on getting system information. It also coincides with how much my repository fork was behind: [Wayback: jpluimers/osquery commits/Archive: jpluimers/osquery commits].

Fast forward to now, the breath of systems I’m involved with has widened, so I was glad to see that Kristian Köhntopp mentioned it:

So time to try it again (:

The links he mentioned:

  • [Wayback/Archive] Welcome to osquery – osquery

    osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive.

  • [Wayback/Archive] Welcome to osquery – osquery: High Level Features
    The high-performance and low-footprint distributed host monitoring daemon, osqueryd, allows you to schedule queries to be executed across your entire infrastructure. The daemon takes care of aggregating the query results over time and generates logs which indicate state changes in your infrastructure. You can use this to maintain insight into the security, performance, configuration, and state of your entire infrastructure. osqueryd‘s logging can integrate into your internal log aggregation pipeline, regardless of your technology stack, via a robust plugin architecture.
    The interactive query console, osqueryi, gives you a SQL interface to try out new queries and explore your operating system. With the power of a complete SQL language and dozens of useful tables built-in, osqueryi is an invaluable tool when performing incident response, diagnosing a systems operations problem, troubleshooting a performance issue, etc.

  • [Wayback/Archive] osqueryi (shell) – osquery
  • [Wayback/Archive] Aggregating Logs – osquery
  • [Wayback/Archive] AWS Logging – osquery

Productivity tips by Florian Haas and David Moreau-Simard: the mottos you work by

Posted by jpluimers on 2021/12/30

My own motto: learn new things every day.

Florian:

[Archive.is] Florian Haas 🇪🇺 on Twitter: “Docs or it didn’t happen.… “

David:

[Archive.is] ☁David Moreau-Simard on Twitter: “Hey software and system folks, I’m curious: what are some of the mottos you work by ? I’ll start:

Via Florian’s pinned Twitter post I found while writing media.ccc.de – No, we won’t have a video call for that! (Communications in distributed teams by Florian Haas).

GitHub – TimeToogo/tunshell: Remote shell into ephemeral environments 🐚 🦀

Posted by jpluimers on 2021/11/25

Cool: [Wayback/Archive.is] GitHub – TimeToogo/tunshell: Remote shell into ephemeral environments 🐚 🦀

Via: [Archive.is] Jan Schaumann on Twitter: “This looks neat: on-demand remote shell into ephemeral environments, e.g. CI/CD pipeline container. Both sides fetch a client, use rendezvous server to negotiate session info, then establish connection or fall back to proxy through rendezvous. “

OpenSuSE tumbleweed switched to using /etc/sudoers.d which broke yast module sudo somewhere mid 2020

Posted by jpluimers on 2021/11/09

Mid 2020, I re-installed a Raspberry Pi 2 box based on OpenSuSE Tumbleweed.

To my susprise the yast2 module sudo could not write the configuration.

It appeared that /etc/sudoers had become readonly and a new /etc/sudoers.d was created.

You can use visudo to edit files in that directory without potentially losing changes in /etc/sudoers during upgrades. I think that is a good move.

To bad the yast module failed because of it.

More on visudo and the /etc/sudoers.d directory:

Chocolatey parameter order: `–yes` becomes before `–force`

Posted by jpluimers on 2021/09/08

Not sure why, bit if you want to force install a package, answering yes to all prompts, the chocolaty parameter order needs to be --yes --force instead of --force --yes.

This works:

choco install --yes --force git.install --params "/GitAndUnixToolsOnPath /NoGitLfs /SChannel /NoAutoCrlf /WindowsTerminal"

This fails:

choco install --force --yes git.install --params "/GitAndUnixToolsOnPath /NoGitLfs /SChannel /NoAutoCrlf /WindowsTerminal"

The user and the not so standard OSI 7 layer stack of compromises: xkcd Stack

Posted by jpluimers on 2021/02/26

Doing full stack development and operations requires one to think about compromises too. Randall Munroe did just that and created an OSI 7 layer like [WayBack] xkcd: Stack episode 2166:

Title text: Gotta feel kind of bad for nation-state hackers who spend years implanting and cultivating some hardware exploit, only to discover the entire target database is already exposed to anyone with a web browser.

And of course there is also a [WayBack] ExplainXKCD 2166
