MySQL for the System Administrator at SeaGL

SeaGL accepted my MySQL for the System Administrator talk. SeaGL is the middle of November in Seattle.

They haven't yet published the talks, so here's my proposal.

There's always a small database somewhere that gets pushed to system administrators without DBA support. Learn some basic skills for maintaining that database. The same skills will help in the middle-ground between sysadmin and DBA.

Verifying debian images signatures and checksums

Verifying signatures

Debian's CD verification page doesn't explain how to find and use the keyring from the package.

This page will explain how to get the keyring package and use it to verify the gpg signatures for the checksum files if you are running debian. The directions will likely work for any debian-based distribution.

Install debian-keyring ( sudo apt install debian-keyring ). Also install gnupg if it isn't already installed ( see GnuPG sidebar for details ).

Monitoring, bluetooth beacons and DEFCON for August PLUG mtg

Chris from Elastic's Kibana team will demo his not yet released project on Alerting and Rhythm ( a server metrics UI ).

Ed will give us an intro to Eddystone Bluetooth Beacons. Perhaps he will talk about the insecurity of most

Phil will give us a short review of his DEFCON trip. Speaking of DEFCON, perhaps Ed will talk about the insecurity of bluetooth smart locks.

FLOSS Stammtisch moved to Boulders on Southern in Mesa

The Free Software Stammtisch has moved to Boulders on Southern, near Fiesta Mall in Mesa. We're happy to return to Boulders and the new location will work better.

The original, Boulders on Broadway, was great, but has little parking and a very popular Tuesday night trivia. The owner is glad to have us return to the new location. He came by our first night to make sure everything was running well for us.

Great tech resume workshop turnout

We filled the room for the Tech Resume Workshop. It was great to see a good turnout of both job seekers and those volunteering to help with resume feedback and practice interviews.

Thanks to the volunteers who showed up to help!

We will likely hold another job event either in November or January. Still debating. The next event will be a job night. The goal is go have sysadmins, developers and hiring managers from companies that are hiring come out looking for people to fit the openings. We had some of that this time around as well :).

Tech Resume Workshop @ the FLOSS Stammtisch

This month's Free Software Stammtisch will feature a no cost tech resume writing workshop.

Despite low unemployment in the tech industry, it is still difficult to get a start in the industry.

On this Tuesday, 2013Sep17, there will be a tech resume workshop starting at 18:00. It will run up to two hours.

The workshop will specialize on resumes for technical fields such as system administration, development, IT/MIS, NOC and network administrator.

scalable log storage and analysis at PLUG

This Thursday Kibana creator Rashid Khan will talk scalable log storage and analysis at PLUG. His talk will cover patterns for log shipping, the problems in traditional centralized log storage, as well as issues with syslog shipping overall. We'll explore the options in the open source space, and define a stack that can be gradually merged into a legacy syslog network, with further optimizations as we later spin down the legacy redundant logging infrastructure.

comparing strings in the shell

While creating materials for my bash class I needed to create some globbing exercises for my students.

It occured to me that a string operator and a comparison to the null string can be used to check if something is a substring of another value.

Sure, you can use Substring Expansion to see if the substring is at a known location such as "Does the value of $foo start with 'bar'?", but length and location are often unknown.

Say, for instance, I wanted to know if it's a word a Dalek would shriek? Easy to do with regular expressions: grep ate$ /usr/share/dict/words.

CentOS Dojo this Friday in Scottsdale

CentOS has started a new series of one day conferences. The second CentOS Dojo is taking place in Scottsdale this Friday. Karanbir Singh is in town to lead the conference.

Job Night @ Stammtisch

ANNOUNCEMENT: Job Night @ Stammtisch! The Free Software Stammtisch is hosting a job night at this coming east valley event on Tuesday, 2012Oct16. The goal is to bring in engineers and managers from groups that are hiring in addition to job seekers and recruiters. For technical positions it's much better to talk directly to the team that is hiring.
