  • About process limits, round 2

    htop

    I was wrong. After the other blog post About process limits, some people contacted me with additional data and information. I myself continued to investigate on the issue, so I have new facts.

    I read again the source code of the slapd daemon and the picture seems clearer now.

  • About process limits

    Graphs

    The other day I had to deal with an outage in one of our LDAP servers, which is running the old Debian Wheezy (yeah, I know, we should update it).

    We are running openldap, the slapd daemon. And after searching the log files, the cause of the outage was obvious:

  • Debian is a puzzle: difficult

    Debian is a puzzle

    Debian is very difficult, a puzzle. This surprising statement was what I got last week when talking with a group of new IT students (and their teachers).

    I would like to write down here what I was able to obtain from that conversation.

  • My FLOSS activity in 2016

    GNU Linux

    The year 2016, which is about to end, has been full of work and contributions to the FLOSS comunity.

    Most of my focus goes to two important projects: Debian and Netfilter. This is no coincidence, since my main interests in the IT world are systems and networks.

  • Great Debian meeting in Seville

    Debian meeting Seville

    Last week we had an interesting Debian meeting in Seville, Spain. This has been the third time (in recent years) the local community meets around Debian.

    We met at about 20:00 at Rompemoldes, a crafts creation space. There we had a very nice dinner while talking about Debian and FLOSS. The dinner was sponsored by the Plan4D assosiation.

  • nftables in Debian Stretch

    Debian - Netfilter

    The next Debian stable release is codenamed Stretch, which I would expect to be released in less than a year.

    The Netfilter Project has been developing nftables for years now, and the status of the framework has been improved to a good point: it’s ready for wide usage and adoption, even in high-demand production environments.

  • The day I became Debian Developer

    Debian

    The moment has come. You may contact me now at arturo@debian.org :-)

    After almost 6 months of tough NM process, the waiting is over. I have achieved the goal I set to myself back in 2011: become Debian Developer.

    This is a professional and personal victory.

  • About Pacemaker HA stack in Debian Jessie

    Debian - Pacemaker

    People keep ignoring the status of the Pacemaker HA stack in Debian Jessie. Most people think that they should stick to Debian Wheezy.

    Why does this happen? Perhaps little or none publicity of the situation.

    Since some time now, Debian contains a Pacemaker stack which is ready to use in both Debian Jessie and in Debian Stretch.

  • Initial post

    jekyllrb

    Finally, I decided it was time to switch from blogger to jekyllrb hosted at github pages.

    My old blog at http://ral-arturo.blogspot.com.es will still be online as an archive, since I don’t plan to migrate the content from there to here.
