Mark Callaghan at the Korean MySQL Power User Group

The Korean MySQL Power User Group gets a special guest speaker next weekend (Oct 31 2015 – 4pm – 4:33’s offices in Gangnam — nearest train stop is Samseong station, Line 2 — post requires Cafe Naver login) — Mark Callaghan (Small Datum, @markcallaghan, and formerly High Availability MySQL). I’ve been to many of their meetups, and I think this is a great opportunity for many DBAs to learn more about how Mark helps make MySQL and MongoDB better for users at Facebook. I’m sure he’ll also talk about RocksDB.

After that, as usual, there will be a DBA Dinner. This time the tab gets picked up by OSS Korea. See you next Saturday — Halloween in Seoul will have added spice!

osquery is neat

Facebook recently made opensource, osquery. It gives you operating system data via SQL queries! Its very neat, and you can test this even on MacOSX (it works on that platform & Linux). It is by far the project with the most advanced functionality, linked here in this post.

I noticed that rather quickly, there was a PostgreSQL project, called pgosquery, based on Foreign Data Wrappers with a similar idea. (apparently it was written in less than 15 minutes; so a much lower learning curve than the regular MySQL storage engine interface)

I immediately thought about an older MySQL project, by Chip Turner (then at Google, now at Facebook), called mysql-filesystem-engine. This idea was kicking around in 2008. I was intrigued by hearing about this at a talk (probably at the MySQL Conference & Expo); it’s a pity no one took this further.

On a similar tangent, did you also know that there is the option to use MySQL as storage via FUSE (see: mysqlfs)? An article by Ben Martin shows some practical examples.

At its heyday, MySQL had many storage engines (maybe around 50). Wikipedia has an incomplete list. I see some engines on that list, and think that some of these folk are also creating MongoDB backends — competition. At MariaDB we are probably shipping the most storage engines of any MySQL-based distribution, however I think we could be doing an even better job at working with upstream vendors, and figuring out how to support & augment business around it.

Korean MySQL Power User Group

If you are a MySQL power user in Korea, its well worth joining the Korean MySQL Power User Group. This is a group led by senior DBAs at many Korean companies. From what I gather, there is experience there using MySQL, MariaDB, Percona Server and Galera Cluster (many on various 5.5, some on 5.6, and quite a few testing 10.0). No one is using WebScaleSQL (yet?). The discussion group is rather active, and I’ve got a profile there (I get questions translated for me).

BBQ starters for tonight's DBA dinner in SeoulThis is just a natural evolution of the DBA Dinners that were held once every quarter. Organised by OSS Korea, and sometimes funded by SkySQL, people would eat & drink, while hearing a short message about updates in the MySQL world (usually by me, but we’ve had special guests like Werner Vogels, CTO Amazon; recently we’ve seen appearances by Monty, Patrik Sallner, Michael Carney where mostly all we do then is eat & drink).

So from meetups to getting information online, in a quick fashion. Much hunger for open source in Korea, very smart people working there on services feeding the population (where some even make it outside of the local market). The future of open source in Korea is definitely very bright.

Remembering our ideals & staying in control

Hactivist Richard Stallman takes on proprietary software, SAAS and open source — Tech News and Analysis: “‘Our ideals become forgotten,’ he said of open source eclipsing free software, and encouraged the audience to keep talking about free software.”

Richard Stallman is spot on. Read the whole article. I hope video makes its way online, because RMS is right. 

It further augurs well that I spoke with Mårten Mickos on Twitter today (he’s a former CEO of mine and a brilliant mind) and we got chatting on control. He says, “Every time you choose convenience, you lose a little control.” An interesting conversation followed naturally.

Leaves me a lot to think about as I have over time chosen convenience over control and clearly it has come by because I need to refresh on my ideals.

Need private cloud services? Time to start entrepreneurs

Seeing through appearancesPRISM and the NSA has blown up recently. We have Malaysian politicians worried about it naturally. The opensource zealot will tell you need to prism break.

I’m more pragmatic. I prefer opensource. But if there are no opensource alternatives, I will use the proprietary tool. This extends to cloud software like Google Docs/Drive. Its great at collaboration, which is something you can’t get close. 

I was suggested that FENG Office might work. I retort that it’s not the easiest install and it requires maintenance. Also, with PRISM, the web host clearly matters (they look at the pipes). I didn’t even think to consider LibreOffice due to lack of collaboration in desktop software.

In Malaysia, next generation children are going to be roped into the online Google world via Chromebooks.

So my thinking is simple: if there are no alternatives (to being hosted in the US or to having better controls over your cloud offerings), you should start one. This can be a great business. As the FT says, data privacy is a handy weapon to challenge the titans with.

Watch this video of Fred Wilson. If the world thinks Dropbox is suddenly insecure, its ripe for alternatives to crop up. It also doesn’t mean that people just start using alternative services… DuckDuckGo might have had a 50% increase in search traffic, but all that search traffic may be what Google processes in a moment ;)

This PRISM stuff isn’t going to blow away anytime soon. Now’s the time to come up with matching software that has additional features (like privacy, encryption, etc.). Maybe Kim Dotcom was ahead of the curve with Mega?

Immediate thoughts on Business Source Licensing

Sunrise at SanurI just got back from a vacation to see articles about Business Source Licensing. I’ve divided my thoughts into four parts here: Opensource and its merits, Is unpaid opensource usage bad?, MariaDB’s “Problem”, Business Source Licensing. If you haven’t read them yet, here’s some mandatory reading:

  1. Open source: Its true cost and where it’s going awry by Monty Widenius
  2. MySQL Co-Founder Wants You To Pay Up For Open Source

There is much abuzz on Twitter as well. From the likes of Mike Olson (who is right, MariaDB may have issues that are different to other OSS products – no two OSS projects/products are alike), to a lengthy conversation between Jim Jagielski & Matt Asay, as well as another conversation spurred by Matt Asay.

Now for some of my own commentary.

Opensource and its merits

Companies have been heavily using opensource and the reason they like this is because it is open. They don’t pay for licenses like proprietary software. They use opensource because they don’t have to pay for support, services, or anything around it. Countries have pro-opensource policies so that they can empower local citizens and further strengthen their sovereignty. This is what makes opensource popular: the fact that the software comes to you with many freedoms.

Is this bad for companies building businesses around opensource software products? Well, kind of. It means you have to provide real value before someone decides to pay you. And if for some reason you price yourself out of the market, companies choose to hire resources internally. This is the beauty of opensource. Many companies I know have started to use RHEL licenses from Red Hat; once they decide they see less value from the updates or the knowledgebase, they switch to CentOS at their next cycle. No problem there.

Is unpaid opensource usage bad?

I’m going to say that I disagree with Monty and think that he is wrong here:

“The more people are using it and, in these cases, abusing the whole idea of open source by not paying back either with development or money to help projects, it is actually destroying open source.”

I really don’t think opensource is destroyed by having many users and lacking corporate sponsors. This is the way of opensource and has been for a long time. Apple makes use of CUPS to ensure printing works – they did so long before they hired their main developer. We all benefitted from Samba which is how we talk to Windows printers/shares/etc. which had no real commercial company around it (Linuxcare, then IBM, then other providers funded the work). LibreOffice has always existed with lots of work by various distributors of (via the ooo-build system), which is why the project took off so fast.

MariaDB’s “problem”

When there is commercial need for opensource, the corporate sponsors will arise. It takes a long time to get to a stage where you are going to get profitable in an opensource services or infrastructure company. Red Hat didn’t get to a billion dollars overnight. Neither did MySQL.

I will not comment on the financials of Monty Program, SkySQL or how tough it has been to bootstrap the MariaDB project because I clearly am privy to information there. I am particularly proud of how we’ve done a relatively great job at getting MariaDB users and distribution, all on a bootstrap marketing/PR budget with no professional help :-) However, I will reminisce another day.

Simply put: if Oracle stopped producing opensource MySQL or decided that they would shut it down, there would be immediate need for MariaDB and the corporate sponsors would come in throngs. The truth is that Oracle continues to produce MySQL as an opensource product. It may not be a full opensource project (internal trees, delayed public pushes, private bugs database, internal mailing lists, etc.) that follows “the architecture of participation”, but it is still an opensource product. This is what has enabled people to take MySQL and extend it further. Look at the Facebook 5.6 tree, or the Twitter 5.5 tree.

There is talk about the dual-licenses that MySQL chose to use. I remember a time when the connectors were LGPL. They were then relicensed as GPL. They still are. But I think we effectively nipped this with the: MariaDB LGPL Java client, MariaDB C Client Library, and the BSD drizzle stuff.

Business Source Licensing

Now for the bits on business source:

“The whole idea with business source is actually very trivial. It is a commercial licence that is time-based and which will become open source after a given time, usually three years. But you can get access to all the source. You can use it in any way but the source has a comment that says you can use it freely except in these circumstances when you have to pay,” Widenius said.

“You’re forcing a small part of your user base to pay for the restrictions, which can be if you’re making money from [the software], if you have more than 100 employees, or you’re a big company or something like that. So you’re forcing one portion of your users to pay. But because it’s time-based, everybody knows that you can still contribute to the project,” he said.

“Because you have the code, you know that if the vendor does something stupid, somebody else can give you the support for it. So you get all the benefits of open source except that a small portion of users has to pay. As long as you continue to develop the project, each version still gets a new timeline of three years.”

Hmm. I see many people commenting that MariaDB might become business source licensed. I am here to tell you that MariaDB is GPLv2 software. It will stay GPLv2 software.

Reading the definition of business source licensing, it is nothing like what Matt Asay portrays it to be:

“Business source is simply proprietary software released under a Microsoft-esque shared source license that magically becomes fully open source after a period of time.”

I’m sorry but the description above is pretty clear. This is nothing like Microsoft shared source. It is code that becomes licensed under an OSI-friendly license after a time-period; however everyone using the software gets the code. How does one enforce payments? I don’t know. What are the conditions requiring you to pay? I don’t know.

At this stage, I am open to thoughts on such a licensing model but I have no firm thoughts on this myself. The best description of how this works is given above by Monty.

Update: Sun 2 Jun 2013 17:33:53 MYT Monty has an update on business source licensing in a comment on Matt Asay’s column.
