Speaking at LinuxCon Europe 2012 in Barcelona (Nov. 5-9)

nospam@example.com (Lenz Grimmer) — Tue, 30 Oct 2012 01:05:00 +0100

I feel like I just got back home from Oracle OpenWorld (check out my pictures) and some vacation, but I'll be on the road again next week to attend LinuxCon Europe in Barcelona. I'll be there from Monday (Nov. 5th) until Wednesday evening. Oracle is sponsoring the event and we'll have a booth at the exhibition area (booth #19), handing out free Oracle Linux and Oracle VM DVDs. I'll be at the booth every now and then and plan to give a short introduction and live demo of Ksplice rebootless updates on Monday evening (6:00pm).

Two colleagues and myself will also give some presentations:

Status of Linux Tracing - Elena Zannoni, Oracle - Tue 6th, 14:20
OCFS2: Status and Overview - Lenz Grimmer, Oracle - Wed 7th, 10:40
MySQL Security Model and pluggable authentication - Kristofer Pettersson, Oracle - Wed 7th, 13:50

I look forward to meeting many people I still know from the SuSE days and to learn more about what's new in Linux - the schedule looks very promising and it will be a tough challenge to pick the right talks. And if you happen to be in Barcelona these days, I'd like to recommend two related events:

On Monday evening (Nov. 5th, 8:00pm), there will be a "Cluster / Storage / HA Geek Dinner" which I plan to attend. Please get in touch with Florian Haas directly for an invite to the Google+ Event. Thanks to Florian and Lars Marowsky-Brée for setting this up!
A week later, on Tuesday (Nov. 13th, 7:00pm), there will be a MySQL community event "State of the art in MySQL high availability and replication", including a presentation on the topic by Robert Hodges and Giuseppe Maxia from Continuent, followed by a networking event including beer and snacks.

I wish I could attend that second one as well, but I'll hopefully be back at home by then again...

UPDATE 2012-10-30: The direct link to Google+ Event did not work - Sorry for the inconvenience. Updated the RSVP instructions accordingly.

Upcoming speaking engagements: Oracle OpenWorld, DOAG Conference

nospam@example.com (Lenz Grimmer) — Tue, 18 Sep 2012 01:44:22 +0200

It's that time of the year again — the summer holidays are over and the conference season starts!

I'm very excited to be at Oracle Open World in San Francisco again, where I will pretty busy. On Saturday and Sunday I will attend MySQL Connect, primarily to man the Oracle Linux booth in the exhibition area. But I hope to catch some of the talks as well (I shared my favourite sessions with Keith Larson from the MySQL team in this interview). During Open World, I will help out manning the Oracle Linux demo pods in the exhibition grounds in Moscone South, where we will showcase Oracle Linux with Ksplice and related technologies. I also have a joint presentation with two of our customers about "Top Technical Tips for Automatic and Secure Oracle Linux Deployments" and I've prepared two hands-on lab sessions "Oracle Linux Storage Management with LVM and Device-Mapper" and "Oracle Linux Package Management: Configuring and Enabling Services". Both hands-on lab sessions will actually be run twice. The lab sessions were quite popular last year, I look forward to moderating these again.

In November, I'll be at the DOAG Conference in Nuremberg, to give a joint presentation with my colleague Manuel Hossfeld about "Oracle Linux - best practices and benefits" (in German). We also plan to request a slot for a BOF/Unconference about Linux, I'm curious about the feedback and discussions that will arise during these sessions.

If you happen to be around these conferences and would like to meet, please get in touch!

Back in Linux land

nospam@example.com (Lenz Grimmer) — Thu, 16 Jun 2011 09:46:19 +0200

It's been a while since my last post on this blog; I definitely need to get back into the habit! One of the reasons for my radio silence was that I switched roles here at Oracle. After having been with the MySQL team for 9 years, I felt it was time for a change. Fortunately I did not have to look far – I'm now a member of the Oracle Linux product management team and I am having a lot of fun there.

However, I realized that while I was an active Linux user on the desktop, quite a lot has happened on the enterprise and data center side of things. Linux has really come a long way and I am glad to be back in this field, drinking from the firehose and learning a lot about recent developments and technologies. For me, this is kind of going "back to my roots", as I have been deeply involved with Linux at SuSE before I joined MySQL in 2002.

Anyway, I'm still alive and you can expect to hear more about Linux and less about MySQL from me on this blog in the future. I also started writing for the official Oracle Linux Blog as well as the OTN Garage blog – watch these spaces for future posts from me, too.

In addition to that, my travel schedule is also filling up again: at the end of this month I'll be speaking at the fisl12 conference in Brasil and Oracle OpenWorld in San Francisco later this year. I also submitted talk proposals to the DOAG conference and the UKOUG conference. Looking forward to it!

Upcoming speaking engagements: SF MySQL Meetup, FOSDEM, GUUG FFG and COLLABORATE 11

nospam@example.com (Lenz Grimmer) — Thu, 20 Jan 2011 22:34:00 +0100

My calendar is filling up with speaking engagements about MySQL at various events quickly. Here is a list of events for the coming months where I'll be present:

On Wednesday, January 26th, I will be speaking about MySQL High Availability Solutions at the San Francisco MySQL Meetup. I feel honored for having been invited to speak there and I'm quite excited that venue is fully booked! I look forward to meeting so many MySQL users in one place.
On Saturday, February 5th, I'll be attending and speaking at the MySQL & Friends Developer Room at FOSDEM 2011 in Brussels, Belgium. I helped organizing the DevRoom and preparing the schedule for this event. We have a great lineup of speakers and topics, and I will speak about MySQL 5.5 there. I've been to FOSDEM many times before and it's one of the OSS conferences in Europe that I really enjoy coming back for every year.
On Thursday, March 24th I'll be in Weimar, Germany, attending the "GUUG-Frühjahrsfachgespräch 2011", a conference organized be the German Unix User Group (GUUG). The topic of my session is MySQL Replication Technologies - an Overview (in German). Erkan, well-known member of the German MySQL community will also be there to talk about "Toolbox MySQL", giving an introduction to the MySQL plugin API and technology.
Finally on April 10th-14th I will be in Orlando, Florida to attend and speak at COLLABORATE 11. Organized by the Independent Oracle Users Group (IOUG), this is a fairly large conference covering a wide range of Oracle Applications and Technologies. This year, they have more than 50 sessions on MySQL, provided by both well-known speakers of the MySQL community as well as Oracle employees. The MySQL talks will be given in one track, which spans from Monday till Thursday. So at least one does not have to choose between several interesting MySQL topics at the same time

If you happen to be around at any of these events, please stop by!

I've also submitted a number of MySQL talks for LinuxTag, which will take place in Berlin, Germany on May 11th-14th. I hope that my proposals are being considered and I would like to encourage you to submit one, too! The call for papers is still open until January 25th and it would be great to have some more MySQL content in the program...

Oh, and don't forget to mark your calendars for MySQL Sunday at Oracle Openworld 2011 later this year (October 2nd-6th)! I unfortunately missed last year's event, but this is going to be the conference with the largest MySQL show, lots of news and updates, and plenty of opportunities for networking. You can already register for the event at a "Super Saver" discount until April, 1st here.

Back from Lisbon, off to Nuremberg

nospam@example.com (Lenz Grimmer) — Mon, 15 Nov 2010 13:31:06 +0100

Yesterday afternoon I returned from the SAPO CodeBits 2010 conference, which took place in Lisbon, Portugal. Just like the previous year, CodeBits has been a great conference to be at and I am grateful for having been selected for participation. Thursday, the first conference day was quite a busy one for me — I gave two presentations in a row:

Afterwards, I also participated in a panel discussion about "To SQL or not to SQL", together with representatives from other open source databases (@fdmanana from CouchDB, @antirez from Redis and @bpedro for PostgreSQL). It was an interesting but somewhat slow discussion and the overall conclusion is still the same: there's more than one tool for a given job, choose carefully what your requirements are and don't just blindly believe the hype.

On Friday, I had some more time to attend other people's presentations. In the evening I took part in another panel discussion about Physical Computing. I also had the "opportunity" to try one of the Nuclear Tacos (Video) they served — I have never had something that hot before. Ouch! Fortunately my tastebuds recovered in time for the speaker's dinner, which took place later that evening. We went to a Rodizio restaurant nearby, the food was plenty and delicious!

Saturday was a pretty low activity day for me. I spent some time in the DIY corner, doing some Arduino hacking. Later that day I attended the project presentations and the closing keynote. Unfortunately a majority of the content was in Portuguese, so I only got parts of the content. But it was still fun! I've published my pictures of CodeBits on Flickr, I hope you enjoy them

Later today, I will be travelling to the DOAG Conference 2010 in Nuremberg, Germany. I'll be giving two talks (in German) there on Wednesday, 17th:

I already received my speaker badge for this conference (see the picture below). Cool idea: you can use the public transport facilities (Buses, Trams) for free, by presenting this card!

There will also be a MySQL Community Meetup on Tuesday, 19:00 at the Press Center of the Congress Center East. If you're around, you're more than welcome to join us there!

Next up in the conference schedule for this year is the UKOUG Conference in Birmingham, UK (Nov. 29th - Dec. 1st). We helped them with setting up a MySQL session stream, and they've created an interesting lineup of talks. I'll be speaking about Making MySQL Administration a Breeze - A Look Into a MySQL DBA's Toolchest. See you there!

Preparing for the MySQL Conference

nospam@example.com (Lenz Grimmer) — Sun, 11 Apr 2010 03:12:35 +0200

Hello from Santa Clara, California! I've arrived here yesterday and am staying with Giuseppe and Jan in the same hotel. Currently, the weather isn't that nice and we're all busy making preparations for the upcoming MySQL conference next week.

I'm fiddling with my slide deck for my talk about "A look into a MySQL DBA's toolchest", realizing that there is such a wealth of great tools that it's unlikely to cover them all in a 45-minute session. But I hope it will give the audience some inspiration about what tools to take a closer look at!

On a related note, I've just reconfigured Planet MySQL to display 30 instead of 20 entries on the front page – I assume next week there will be slightly more postings than usual...

Thoughts about working in a distributed organization

nospam@example.com (Lenz Grimmer) — Fri, 12 Mar 2010 21:00:00 +0100

I've been working in a fully distributed work environment for almost 8 years now (I joined MySQL AB in April, 2002). Therefore I've been reading Toni Schneider's blog post about the "5 reasons why your company should be distributed" with great interest – he raised several points that I fully agree with and which I covered in my talks about "Working for a virtual company - how we do it at MySQL" at last year's next09 conference (slides, video) and at FrOSCon 2009 (video).

However, Toni draws a profusely positive picture here, or, as my dear colleague Dean pointed out "The blog overly simplifies the realities of a distributed workforce, making it sound like it's all ponies and rainbows".

Back from SAPO Codebits in Lisbon - a summary

nospam@example.com (Lenz Grimmer) — Mon, 07 Dec 2009 15:39:23 +0100

Last week, my colleagues Giuseppe, Kai and myself attended the SAPO Codebits event in Lisbon, Portugal. Codebits is an annual, invite-only hacking event, which went on for three days. The venue they chose this year was the "Cordoaria", a former rope factory located in the Belém district, close to the 25 de Abril Bridge (which is an impressive sight!). I have been told that the Cordoaria is the longest building in Portugal and I have no doubts about that! The building is so long that the crew used bicycles to get from one end to the other. I've taken a number of pictures from the event as well as from Lisbon itself, you can find them in this flickr set.

The organizers described this year's event as follows:

3 days. 24 hours a day. 600 attendees. Talks. Workshops. Lots of food and beverages. 24 hour programming/hacking competition. Quizz Show. Rock Band Contest. Lots of gaming consoles. More food. More beverages. More coding. Sleeping areas. More fun. An unforgettable experience.

I wholeheartedly agree, we had a great time! The conference started with sessions and presentations on a wide range of topics on the first two days. Afterwards, a 24-hour programming contest was held. I was invited to give two talks, one being my all-time favourite about "MySQL High Availability solutions" (slides, video), the other one was titled "Why you should be using a distributed version control system (DVCS) for your project" (video, slides). Both went quite well and the feedback I received was pretty positive. Giuseppe talked about "MySQL Schema Migration" (slides, video) and gave an "Introduction to Gearman" (video). Kai's talk was titled "Think before you develop" (video) and gave a nice roundup of tips and best practices for setting up and developing new web projects.

The Codebits session schedule was filled with amazing and interesting talks in four parallel tracks. Sometimes it was hard to choose – some other talks I attended and enjoyed:

Walter gave a lockpicking workshop after his presentation, which I attended as well. I was quite impressed (and a bit shocked) to find out how easy many locks can be opened this way! Later that evening there even was a live band named "Pornophonique" playing (one guy with a guitar, the other one using an Nintendo Game Boy for making music), but I missed that show as I was too busy opening more locks... Fortunately the concert and most of the sessions were recorded on video (in excellent quality) and are already available from the SAPO video pages. Kudos for this speedy service!

But this just matches my overall conclusion of this event: very well organized, great speakers and venue. Thanks to the organizers for having us, we really enjoyed our stay!

My upcoming event schedule for this year

nospam@example.com (Lenz Grimmer) — Mon, 26 Oct 2009 13:47:02 +0100

This time of the year is usually a very busy one, as there are plenty of events and conferences to attend. Just take a look at our calendar of OSS events on the MySQL Forge to see what I mean! Here's a quick summary of the ones that I will attend and speak at until the end of this year:

On November 14-15, I'll attend the openSQL Camp in Portland (OR), USA. I missed the first one that took place in Charlottesville (VA) in 2008, but had a lot of fun organizing the European Edition earlier this year. The upcoming one will be more like an unconference again - the list of proposed sessions looks very interesting and the attendee list reads like a "who is who" list of the OSS database community.

On December 3-5, I'll be joining Giuseppe at SAPO Codebits in Lisbon, Portugal, which is going to be a very cool event: "3 days. 24 hours a day. 600 attendees. Talks. Workshops. Lots of food and beverages. 24 hour programming/hacking competition. Quizz Show. Rock Band Contest. Lots of gaming consoles. More food. More beverages. More coding. Sleeping areas. More fun. An unforgettable experience". I will be talking about my favorite topic of MySQL High Availability (I'm currently working on revising my slides based on several excellent discussions about MySQL HA that happened on Planet MySQL in the past weeks) and about the benefits (both social and technical) of using a distributed revision control system (DVCS) like bazaar, git or mercurial for your open source project.

Shortly after Codebits, I will attend SLAC 09, the "Secure Linux Administration Conference" in Berlin, Germany (December 10-11), where I will give two MySQL-related talks (in German) - my usual suspects, but in revised and extended form: MySQL High Availability solutions and MySQL Backup & Security best practices.

Upcoming events: PHP Unconference and openSUSE Conference

nospam@example.com (Lenz Grimmer) — Mon, 07 Sep 2009 21:48:32 +0200

The summer break seems to be over and the event season is heating up again! There is a number of conferences and events coming up in the next months — here is a quick summary of the events that I plan to attend.

This Friday I will attend an event here in Hamburg: the "Silpion Sommerfest", organized by Silpion (a local IT solutions provider which is a partner of Sun Microsystems as well). I will be there to network and talk about MySQL.

This coming weekend (2009-09-12/2009-09-13), there will be the PHP Unconference here in Hamburg, Germany . It will consist of two days of Barcamp-style sessions about PHP. Sun/MySQL are sponsors of the event and I expect several of my team mates to be there as well. With more than 180 participants, the event is already sold out.

The following week I will be attending the openSUSE Conference in Nuremberg, Germany on 2009-09-17/2009-09-20. I will give the opening keynote on Thursday morning. Titled "Working in a Virtual Community", I will talk about the pros and cons of working in a virtual organization, giving an overview about some of the technical and social aspects that play a role in working with virtual communities.

On December 10th and 11th I will be attending the 4. Secure Linux Administration Conference 2009 (SLAC) in Berlin, Germany. I've been invited to talk about MySQL and will give two sessions about MySQL Backup & Security as well as MySQL High Availability Solutions. The Call for Papers for this event is still open, so if you have a technical, "best practice" talk that might be relevant for system administrators, consider submitting your proposal!

What I have been doing lately in slides, pictures and videos

nospam@example.com (Lenz Grimmer) — Thu, 28 May 2009 15:39:35 +0200

I just realized that I haven't blogged for more than a month! Shame on me. But I will blame it on being away on conferences and vacation for quite some time And if you are following me on twitter, you may have noticed what I was going on in my life and that I did't get hit by a bus...

So what was going on since I returned back home from the MySQL Conference? First off, I uploaded und sorted my pictures from the conference and the Drizzle developer day on Flickr. I also uploaded the slides (PDF) from Colin and myself speaking about "MySQL Server Backup, Restoration, and Disaster Recovery Planning" to the MySQL Conference site and they are now available for download from the session page.

On May 4th and 5th I attended the amoocon in Rostock, Germany - a conference primarily about Open Source Telephony and VoIP, where I gave two talks (in German) about MySQL HA Solutions and MySQL Backup and Security Best Practices. There were several other MySQL-related sessions at this conference (e.g. Geert speaking about MySQL Cluster) and I was quite impressed to learn about how widely used it is in the VoIP/Telephony sector. The PDFs of my slides for both talks are available from the conference web site as well as on my slidespace on SlideShare (a very convenient service that I recently started using). There even is an MP3 and video recording of the HA talk, which is also linked from the session page mentioned above.

Right after the amoocon, I attended the next09 conference, which took place in Hamburg, Germany. On the first day I helped manning the Sun booth for some time (Sun Startup Essentials Germany was a sponsor of the event) and listened to some talks, on Wednesday I gave a presentation about "Working for a Virtual Company: How do we do it at MySQL?". A video recording of my talk is available from sevenload. Last time I checked the video was truncated, but I hope they will publish a complete version of it soon. Unfortunately I had a very bad speaking slot - the very first one in the morning (9:00am), after there was a party/social event going on the night before... But luckily there still were ~20-30 people in the audience. This was the first time that I gave this presentation and talked about something less technical, which was actually quite fun! As for the other recent talks, the slides are on SlideShare.

From May 14th to the 16th I was in Verona, Italy to speak about MySQL Backup and Security and bzr - The Bazaar source revision control system at the Italian phpDay. This was quite a nice event with ~150 attendees and Rasmus Lerdorf giving two talks as well. However, many of the sessions were in Italian, so I decided to spend some time walking around the city and taking lots of pictures. I also took a number pictures from the conference, but the light was pretty dim in the room and many shots turned out to be too blurry. Next year they plan to have the phpDay in Rimini - I definitely plan to be there!

Made it to Santa Clara, ready for the MySQL Conference!

Hyatt Regency, Santa Clara
Originally uploaded by Lenz Grimmer

After a long and uneventful flight from HAM to SFO via FRA, I arrived safely in Santa Clara yesterday. Today we spent the day in San Francisco, for some sightseeing (Downtown, Chinatown, Pier 39 and Fishermen's Wharf) and a bit of shopping. It was a very nice and sunny day, the sunlight helped a lot with getting over the jetlag for a while.

But now I'm pretty tired - I look forward to meeting friends, colleagues and members of our community at the MySQL Conference, which starts next week. I will also give a talk together with Colin Charles about MySQL Server Backup, Restoration, and Disaster Recovery Planning as well as moderating a BoF about MySQL Code Contributions, where we will talk about the recent developments and changes that we've implemented (or plan to put in place) to make it easier for developers to contribute code to the MySQL project.

I will try to take lots of pictures during the conference, which will be posted to my MySQL Conference Photo Set on Flickr every once in a while.

Back from Solutions Linux 2009 in Paris, France

nospam@example.com (Lenz Grimmer) — Wed, 01 Apr 2009 17:50:50 +0200

On early Tuesday morning, I made a quick trip to Paris, France, to attend and speak at the Solutions Linux / Open Source 2009 Conference. I've never been to this conference before and was quite surprised about its size - it's actually the largest Open Source event in France and it reminded me a lot of LinuxTag in Germany. Many well-known vendors (e.g. Sun, Novell, Canonical, Bull, etc.) were exhibiting. The also was a large "DotOrg" section for various Open Source projects and I was very happy to see that LeMUG.fr, the official MySQL User Group of France, had a table there, too! A big Thank You goes to Pascal Borghino, who manned that table on his own most of the time and answered questions about MySQL. I walked around the exhibition floor and took some pictures, which I have now posted to my Flickr account.

In addition to the exhibition, there were several parallel tracks with sessions. I was invited to speak about MySQL HA Solutions in the "Aquarium". Unfortunately I had the last slot at that day and they were running a bit behind schedule, so I had only 15-20 people in the audience. But I still had a great time and I received several positive comments about my presentation. I travelled back home early the next day - I wish I had scheduled some more time to attend the conference. I look forward to going there again next year, it was a nice event.

Speaking at phpDay in Verona, Italy (May 15-16)

nospam@example.com (Lenz Grimmer) — Wed, 25 Mar 2009 12:18:41 +0100

My travel schedule is getting quite crowded for the next months - I just received confirmation that I will be speaking at the phpDay in Verona, Italy on May 15-16th. I'll be talking about bzr - The Bazaar source revision control system as well as MySQL Backup and Security - Best practices in the developer track of the conference. I've never been to Verona, but it seems like it's a beautiful city. I look forward to being there!
