Ad blocking

I know I run ads here, but I really don’t think Google AdSense is bad. What is really annoying me? Video, animated graphics, heavy ads, even on sites that I’m paying subscriptions for to read. I’m happy with a subscription and AdSense, but they’re not doing just that! They are consuming my CPU cycles, ensuring that when I’m working on the battery, these tabs are just taking away precious power.

I thought of using AdBlock Plus, but I recall there were some issues with it in the past (maybe around being paid to be whitelisted). So my solutions of choice in the Chrome browser now:

I’m whitelisting some sites, logging into some others (e.g. Forbes), or finding out that some extensions like Buffer is broken (easy fix: on the first site that you try to use the extension on, just whitelist it in Privacy Badger and things will “just work”).

I’ve been on the Internet for over 20 years, and this is the second time I’ve decided to use ad blocking software. Maybe when we’re respected as readers (see: going back to Google AdSense), I will disable the above extensions. Till then, I’m more productive on a battery for just that little longer…

London roadshow wrap-up, see you in Paris next week

Just a few days ago, I presented at the MariaDB Roadshow in London, and I had a lot of fun. While I had canned slides, I did know the topic intimately well, so it was good to get further in-depth. In addition, we had these MasterMind sessions, basically the place to get one-on-one time with Anders/Luisa/or me, I noticed that pretty much everyone said they were buying services afterwards (which more or less must mean the event was rather successful from that standpoint!).

In addition to that, I was happy to see that from attendee feedback, I did have the highest averages – thank you!

So here’s to repeating this in Paris next week — Gestion des données pour les applications vitales – MariaDB Roadshow Paris. I look forward to seeing you there, and I know we are repeating the MasterMind sessions. To fine-tune it, try to bring as much information as you possibly can so our time can be extremely effective.

London in May 2016

I’m happy to be back in London in May 2016, to talk at two events:

  1. The London MySQL Meetup GroupMonday May 9 – 6.30 PM – 9.00 PM – options for High Availability in the ecosystem that one would consider today. This is a cut down from my Percona Live tutorial, which had about 88 registered attendees and about that amount showed up and asked questions even through the break and after. I had a lot of fun, and I expect I will have similar fun in London talking about this area that has changed a lot in recent times.
  2. Data for the Enterprise – MariaDB Roadshow in LondonWednesday, May 11, 2016 from 9:30 AM to 2:00 PM – this should be a fun gathering, and you would think its just for MariaDB Corporation customers, but it isn’t – all are welcome and you should register!

Looking forward to seeing you at these events. And if you want to chat about MariaDB Server, MySQL or anything related in the opensource world, don’t hesitate to drop me a line via email or Twitter @bytebot.

MariaDB Berlin Meetup Notes & Slides

We had the first MariaDB Berlin Meetup on Tuesday 12.04.2016 at the Wikimedia Berlin offices at 7pm. More or less there were over 54 people that attended the event, a mix of MariaDB Corporation employees and community members. We competed with the entertainment at the AWS Summit Berlin which was apparently about 400m away! Food and drink were enjoyed by all, and most importantly there were many, many lightning talks (minimum 5 minutes, maximum 10 minutes – most were about 6-7 minutes long).

The bonus of all of this? Lots and lots of slides for you to see. Grab them from the Google Drive folder MariaDB Berlin meetup April 2016.

  1. Monty talked about improving the speed of connections to MariaDB Server, some work he’s just pushed fairly recently to the 10.2 tree.
  2. Dipti spoke about MariaDB ColumnStore and it is now clear we’ll see some source/binary drop by the end of May 2016.
  3. Sergei Petrunia and Vicentiu Ciorbaru spoke about the upcoming window functions that MariaDB Server 10.2.0 will see (yes, the alpha should be out real soon now).
  4. Jan spoke about InnoDB in 10.2.
  5. Lixun Peng spoke about a fairly interesting feature, the idea to flashback via mysqlbinlog and how you can have a “Time Machine”. I can’t wait for flashback/time machine to appear in 10.2. The demo for this is extremely good.
  6. Kolbe spoke about data at rest encryption using the MariaDB Amazon AWS KMS plugin.
  7. Sanja and Georg went up together to speak about 10.2 protocol enhancements as well as what you’ll see in Connector/C 3.0.
  8. Wlad gave us a good rundown on authenticating with GSSAPI, something you will notice is also available in MariaDB Server 10.1’s later releases.
  9. Johan Wikman gave us an introduction to MariaDB MaxScale, which started off the talks on MaxScale.
  10. Markus talked about the readwritesplit plugin.
  11. Massimiliano went into the Binlog server.
  12. Martin didn’t use slides but gave us an amazing talk titled “Rival concepts of SQL Proxy”; it was very well given and I’ve encouraged him to write a blog post about it.
  13. Community member Ben Kochie, an SRE at SoundCloud gave us a quick talk on Monitoring MySQL with Prometheus and how much they depend on the PERFORMANCE_SCHEMA.
  14. Diego Dupin spoke a little about the MariaDB Java Connector, and the idea was to do a demo but the projector via HDMI seemed to be a bit wonky (this was also true of using my Mac; the VGA output however worked fine). So it was just a quick talk without any deck.

We ended with a quick Q&A session with Monty dominating it. Lots of interesting questions around why the name Maria, licensing thoughts, ensuring all the software we have are in distributions, etc. Some ended up going for pizza while others ended up in a hotel bar at the Crowne Plaza Potsdamer Platz — and the chatter went on till at least 11pm.

Thanks again to Georg Richter who found us the venue and also did a lot of the legwork with Wikimedia Foundation.

Major post-GA features in the 5.7 release!

Interesting developments in the MySQL world – it can now be used as a document store and you can query the database using JavaScript instead of SQL (via the MySQL Shell). There is also a new X Plugin (see: mysql-5.7.12/rapid/) (which now makes use of protocol buffers (see: mysql-5.7.12/extra/protobuf/)). I will agree, this is more than just a maintenance release.

Do get started playing with MySQL Shell. If you’re using the yum repository, remember to ensure you have enabled the mysql-tools-preview in /etc/yum.repos.d/mysql-community.repo. And don’t forget to load the X Plugin in the server! I can’t wait for the rest of the blog posts in the series, and today just took a cursory look at all of this — kudos Team MySQL @ Oracle.

However, I’m concerned that the GA is getting what you would think of as more than just a maintenance release. We saw 5.7.11 get at rest data encryption for InnoDB, and now 5.7.12 getting even more changes. This is going to for example, ship in the next Ubuntu LTS, Xenial Xerus. Today it has 5.7.11, but presumably after release it will be upgrade to 5.7.12. I am not a huge fan of surprises in LTS releases (predictability over 5 years is a nice thing; this probably explains why I still have a 5.0.95 server running), but I guess this small band-aid is what we need to ensure this doesn’t happen going forward?

As for the other question I’ve seen via email from several folk so far: will MariaDB Server support this? I don’t see why not in the future, so why not file a Jira?
