One of the three SREcons worldwide, this was a long and intense conference with a three-day multitrack format and a correspondingly voluminous collection of notes. The crowd felt different from North American one: a lot more “large company” folks (heavy presence from Google, Microsoft, Facebook, and others), a lot more smokers than there would be on this side of the pond, and somewhat more conservative technology choices (the last point is similar to what I felt at DevOpsDays TLV last year as well). ...

This is the first attempt by DataDog to produce a branded conference, and they did not manage to avoid some of the rough edges that usually accompany first-time events. However, the organizers’ response to various crises was commendable: they scheduled additional workshops when the existing ones proved to be significantly undersized, promised to refund some of the people who could not enter because of overcapacity, took contact information to follow up with some attendees, and in general hustled to recover in an admirable fashion. ...

I wrote this report for internal consumption shortly after the conference. As Monitorama 2018 approaches, I thought these notes could be useful for a wider audience to revisit the common themes and interesting questions from the previous year and to see what has been done to address them. ...

This was my second ShmooCon. It was just as fun as the first time, and this time I did various other activities (solving a few of Raytheon’s CTFs, practicing lockpicking, looking at all the codes in the conference program) in between interesting talks. For more details about the conference itself, see the last year’s report. ... Read more

The Tel-Aviv instance of DevOps Days was interesting to me for two reasons. The first one is there’s a ton of innovation happening in Israel, so there’s a chance of hearing new things; yet Israel is far enough from Silicon Valley that its thinking and opinions are distinct from the San Francisco area monoculture. ...

ShmooCon is a security conference held yearly in Washington, DC. With around 2000 participants, it has an audience large enough to fill 3 tracks and provide a range of extra-curricular activities, yet it is much less crazy than events like DefCon (which is ten times the size). ... Read more

As usual, Linux needs a bit of under-the-hood wrenching to get things working. HP is actually doing Linux support commendably compared to its peers (see hplip). However, in this case a bit of extra grease was needed. ... Read more

Currently, there is an explosion of tools that aim to manage secrets for automated, cloud native infrastructure management. Daniel Somerfield did some work classifying the various approaches, but (as far as I know) no one has made a recent effort to summarize the various tools. This is an attempt to give a quick overview of what can be found out there. The list is alphabetical. There will be tools that are missing, and some of the facts might be wrong–I welcome your corrections. For the purpose, I can be reached via @maxvt on Twitter. ... Read more

Today I noticed that my Linode does not restore its iptables configuration after reboot. This is how the investigation progressed. I have opened a ticket with Linode to update the relevant documentation. ... Read more
