I’ve had many dealings with SK Planet, in South Korea, so when they asked me to speak at their inaugural Tech Planet, I jumped at the opportunity. I was already pre-given a topic titled “NewSQL”, so I talked about the evolution of SQL -> Big Data -> NoSQL -> NewSQL, all thanks to papers written by Google research, and then focused on how MySQL & MariaDB is gaining many new interfaces: mariasql, HandlerSocket, dynamic columns, memcached InnoDB plugin, node.js with NDBCLUSTER, CassandraSE, LevelDB, Galera Cluster and more. This is a topic I will talk more about later.
The event was great. It started with a speaker’s dinner in where the CTO of SK Planet & multiple VP’s dined with the speakers. We had a private room at the InterContinental COEX, and started with smoked salmon, Russian crab meat & cream cheese. This was followed on quickly by crab meat soup. The main course was beef tenderloin, mero fish & steamed black rice, asparagus and black garlic. We ended with a cranberry tian with raspberry sauce. This was filled with lots of Equus red wine.
The next day, we had the day of the event itself and it was huge. There were probably over 800 attendees, and SkySQL had a booth maintained by the Korean partners: OSS Korea, PrixMedia, and Oh New Innovation. This was followed by lunch with the CEO of SK Planet with great conversation & food. Started with tuna & avocado, to clear the palate, some lemon sorbet, and a great main consisting of beef tenderloin & king prawn with red wine sauce. We had much to chat about, and as lunch came to a close, it was time for me to give my talk.
It was well attended, there were some good questions, and there are naturally some good action items. I’m glad that the whole ecosystem provided me multiple opportunities to talk about amazing work being done. The press covered the Tech Planet event. I managed to snag an interview as well. More photos of the event at my techplanet2012 tag on Flickr.
All in, an exciting space to be in now. Thank you so much for SK Planet for the invite, and I look forward to being around in 2013.
I caught Made in China on Sundance over the weekend. It was all about the pursuit of an inventor and the trials & tribulations he faced thrown into a new land. It even won several awards. Good film, recommended watch.
It reminded me of my childhood. My job description for the future? I always said I would be a scientist. I always liked building things, from the time I was a kid. When people got toys when they were three years old, I got extension wires. I got my first computer when I was five years old (a family unit no less). This was in 1989. I built computers, soldered circuit boards, basically made things – invention was fun, as were trips to the then Radio Shack in Bangsar, and Pasar Road when I grew a little older.
Building things seems to be coming back with the Maker movement. Many people are inventing the web as we can see. Many people are also copying such inventions. This happens in software as much as it does in the physical world.
Somewhere along the way, I think I’ve lost my way towards invention. Deals. Financing. Chasing the next big thing. News rot. Running the rat race. I think many people are in the same predicament.
Sometimes it pays to step back, look at things from a macro perspective, plot, then execute.
MicroPeak is a miniature peak-recording altimeter. About the same size and weight as a US dime (with battery), MicroPeak offers fabulous accuracy (20cm or 8in at sea level) and wide range (up to 31km or 101k’).
Uses the Measurement Specialties MS5607 barometric sensor.
Includes built-in battery holder for easily replaceable CR1025 lithium battery
Compact design is only 18mm x 14mm or 0.7” x 0.56”. Weighs 1.9g including the battery.
Low power design lasts for over 40 hours in flight.
Auto-poweroff on landing.

The size of the board was predicated with the premise that we needed a battery included to avoid having wiring running between the altimeter and the board, we found some small lithium coin-cell battery holders for the CR1025 battery. These battery holders are rated to hold the battery secure up to 150gs.
We’d already started playing with the Measurement Specialties MS5607 pressure sensor which offers amazing accuracy while using very little power. Taking full-precision measurements every 96ms consumes about .2mA on average. Once on the ground, we stop taking measurements entirely, dropping the power use to around 1µA. It’s also pretty small, measuring only 5mm x 3mm.
For a CPU, this little project didn’t need much. The 8-bit ATtiny85 comes in a 20qwfn package which is only 4mm x 4mm. When run at full speed (8MHz), it consumes a couple of mA of power. Reduce the clock to a pokey 250kHz and the CPU has enough CPU power to track altitude while consuming less than .2mA on average.
To avoid losing the battery, we wanted to avoid having it removed while the board wasn’t in use. So, we added a little power switch to the board. The one we found is good to at least 50g.
Finally, we wanted to find a nice bright LED to show the state of the device and to blink out the final altitude. The OSRAM LO T67K are bright-orange surface-mount LEDs that run happily on 2mA.
We used OSHPark.com to create prototype circuit boards for this project. Because of the small size of the board, each prototype run cost only $2 for three boards. It takes a couple of weeks to get boards, but it’s really hard to beat the price.

Australia’s premier open source conference, linux.conf.au, has announced its second keynote speaker for 2013. Radia Perlman is famous for her work on the Ethernet spanning tree protocol (STP), the ISIS routing protocol, TRILL (the recent standard that improves upon STP), and other technologies that are fundamental building blocks of the Internet as we know it. She has also made many contributions to network security, including assured deletion of data, the protocol for authentication and key establishment in IPSec, trust models for PKI, and network infrastructure that is robust against malicious trusted components.
Radia is currently a Fellow at Intel Labs, specialising in network and security protocols. She is the author of the textbook "Interconnections: Bridges, Routers, Switches, and Internetworking Protocols", and coauthor of "Network Security". She has a PhD from MIT in computer science, holds over 100 issued patents, and has received various industry awards including lifetime achievement awards from ACM’s SIGCOMM and Usenix, and an honorary doctorate from KTH.
The keynote, titled "Reasoning about Networks", intends to show that a lot of what everyone thinks they know about network protocols is actually false. Radia will demonstrate that the field is shrouded in hype and rivalry between competing teams. It is difficult to know what, if anything, is true, since any of the designs can be changed to incorporate ideas from other designs. The talk will cover topics such how to get to the heart of what might be intrinsic differences, separate out orthogonal issues rather than focusing on complete specifications, and comparing technologies without emotion. Radia will also discuss some recent technologies, and help you to separate the hype from the facts.

I didn’t participate in 2012, but in 2013, I’m back on the conference committee for Percona Live Santa Clara. We have an awesome Program Chair in Shlomi Noach, and after much deliberation & commentary, we have a tutorials schedule out now. Expect that the rest of the conference content to be awesome too. Remember, April 22-25 2013 are the magical dates, so register now!
Disclaimer/Bias Warning: For those that don’t know me, I write this as a perspective of a community member. I was the first ever Community Engineer at MySQL, followed by being a Community Relations Manager right up till I left Sun Microsystems. I now work on MariaDB which is a branch of MySQL, so naturally we are in competition for user base. But I’m writing this as a community member at large who cares about MySQL & the ecosystem.
First of, this is a focus on the user ecosystem. I think the MySQL developer ecosystem has never been healthier than it is today – so many branches, forks, features, development trees, etc. Developer ecosystems are for another post, this is all about user ecosystems.
On events during similar timeframes
Sheeri started with calling BS on my post. Great way to start a conversation. I for one didn’t say that Oracle split the community or that Percona did so. I’m not in the job of pointing fingers. I’m just looking at past evidence: London 2012 (Percona, UKOUG), September/October 2012 (MySQL Connect San Francisco, Percona NYC), April 2011 (MySQL Conference Santa Clara, IOUG Collaborate Florida). There may be more events but I can only think of these.
I’ve heard that the April timeframe is bad for Oracle to send engineers to conferences because they have a busy release month. Yet Collaborate in Florida was ok?
Yes, MySQL may be the most popular opensource database today. This is great for the ecosystem that I am in. We can & should have many events, so I totally agree with Sheeri. But do they have to be at the same time? Do they have to ensure that attendees have to choose one or the other?
On spreading MySQL
I am happy that free events now happen in places that previously had no events, like Nairobi & Kenya. MySQL presence was almost unheard of in South America (many users, but we never made it out there to meet with the grassroots), but I’ve seen great amounts of activity there. I’ve even written about this before: a tale of two conferences. London in 2011 was awesome for MySQL all spread by a week – Oracle and Percona had 2 events and there were 2 different audiences from what I could tell.
I was at MySQL Connect this year as well as Percona Live NYC. The amount of intersection in attendees was sparse. In fact, Oracle managed to gather an interesting new crowd for Connect, so all kudos to them!
My wish as a community member (on events)
I wish to see Oracle MySQL employees show up at all events. This includes Percona Live events. I mean a talk from someone developing InnoDB, for example, would be great. It seems that the official line though is: “Oracle is not willing to help other companies’ marketing“. Fair enough. Percona Live is a great marketing event for Percona.
In the same vein I wish to see non-Oracle employees, even those from competitors, show up at Oracle MySQL events. MySQL Connect had 2 talks from Percona. That’s a good start.
I also wish that I get the best MySQL & ecosystem related content at one event. Many people can only make one event (especially when they happen during the same time at different locations). As a busy DBA, I want “the one event to learn it all”. That’s what the MySQL Conferences in Santa Clara used to do. This was a home for people to meetup once a year. This is no longer the case, it would seem.
Keeping MySQL relevant
Another wish that is unrelated to events: I wish MySQL was still spreading.
I speak to many MySQL users. From humble developers to large enterprises.
Oracle’s enemy isn’t MariaDB or Percona Server or the ecosystem at large. MySQL’s enemy is the growing use of other databases. NoSQL solutions are a popular choice; when people realize they want something relational, they don’t think about MySQL as a migration path. Pretty much every migration story I’ve seen suggests it is a migration to PostgreSQL.
Many years ago, you deployed on MySQL first. Today, is it still the first choice for the developer? Is it the second choice?
What about enterprises migrating from the Oracle database? They are well aware whom the new owners of MySQL are.
I saw this published on Josh Berkus’ blog: MySQL-to-PostgreSQL migration data from the451.com. It is worth a read.
I have had many conversations with experienced MySQL DBAs who I would consider rockstar DBAs in the Valley who are now beefing up their MongoDB knowledge. Some job offers are now asking for more than just MySQL knowledge. The naive way to look at it is if you’re getting 2-3 job offers for MySQL work per week. That is today. What about next year? I would like to put on a long term view here.
One more thing
I am truly independent in this. I want to see MySQL succeed. I need it to succeed as I am an ecosystem participant (via MariaDB).
I have heard many people call Oracle ACE/Directors Oracle apologists. I know pretty much all the Oracle ACEs as friends and respect their opinions, so in no way am I going to refer to them as apologists or shills.
Celebrate the Oracle ACE/Director like you would the old/defunct MySQL Guilds.
Let’s work together to make the MySQL user ecosystem healthy!
In may 2012, I went on a little shopping spree on kickstarter. The intention wasn’t to invest in a project but back it. Its clear many people get confused with the concept. Backing a project isn’t like going to a store to buy or pre-order a product either.
Backing a project is rooting for its success. With money, one can only presume that projects execute and whatever was promised gets delivered. It seems however that my kickstarter hit rate is so far a mere 50%.
I backed a project that successfully delivered the goods in September 2012. I was rather thrilled because it clearly made someone’s dreams come true. Another project that I had backed should have delivered on the goals by the end of July.
Sadly, its November and many of the backers haven’t heard back from the project owner. Many comments from concerned backers are posted in the comments section.
Me? I backed what I consider a small amount. In funding, sometimes things fall thru, and in backing projects, sometimes things don’t work out even when the funding goal is reached. Money alone doesn’t make a product!
Is this however a problem? Will someone that has been burnt by a negative backing consider using the Kickstarter platform again? Will it ruin crowdfunding for them?
I don’t have the answers. I will continue perusing the site, backing interesting projects, ensuring people’s dreams can be achieved. Let’s see if my success rate improves over time.
Percona Live London 2012 happens December 3-4 2012. Naturally Oracle has decided to back UKOUG in Birmingham with interesting talks as well, happening December 3-5 2012. This is akin to the recent San Francisco/New York split for MySQL Connect & Percona Live NYC 2012.
Lucky for us, Birmingham’s “MySQL day” seems to be December 5 2012, and by estimates, it takes about 1.5 hours for one to attend both events and see 3 days of MySQL related content.
That aside, I’m hoping this doesn’t happen in 2013. Splitting the community is never a good idea.
I was recently in Japan and picked up in-store a Native Union Authentic Retro POP Phone Handset for Mobile Devices and Tablets. It is a nifty little device that is great when you have to make long calls (think group meetings, conference calls, etc.). It also means I don’t keep my phone to my ear. The audio quality is pretty good as well, and you can hang up on the call from the phone.
It isn’t something I’m carrying when I travel, but it is a welcome addition to the office. Best thing about it? It uses a regular headphone jack, so no worries about it working on my Android, iPhone, or BlackBerry.
Now, would I get away with driving in a car with this? :-)
I had the pleasure to chat with my former CEO, Marten Mickos, at LinuxCon Barcelona on his birthday. Marten is prolific on Twitter (@martenmickos). I’ve always encouraged him to blog, so I’m glad that he now has two blogs: CEO blog at Eucalyptus, as well as another on Wired’s Innovation Insights.
We spoke about many things, but one of them was email. Marten always replies to emails very quickly and it has always impressed me. He told me he felt bad that now he might take up to a week to reply to an email. He jokingly blamed it on age catching up.
It got me thinking about my email backlog. Across all accounts, I am embarrassed to say I have 3,821 messages that I have to process. I’m sure quite a number of those will require replying (even at 10%, that is quite a number).
There is no better time than now to take over my INBOX. I have the next couple of weeks to be home and a little more relaxed, so I’m going to tackle this email backlog. Once I’ve paid off this debt, I plan to answer emails fashionably quick. I mean if Marten, CEO of Eucalyptus, board member at several firms, can do it, so can I.
Thanks Marten for continuing to inspire me to be better.
For additional inspiration, I plan to listen to Believe in Something Bigger Than Yourself. I’m sure it is one of Marten’s better inspirational talks!
Confidence is the honest belief that you’re highly capable of helping others. Arrogance is the honest belief you have nothing more to learn yourself. It’s a fine line, but walk right up to it. (Smugness is arrogance without the talent—these are the people “coaching” others who have never done what they’re coaching.)
linux.conf.au, Australia’s premier open source conference, have announced the first of four keynote speakers for 2013. Andrew "bunnie" Huang is best known as the lead hardware developer of "Chumby", a device designed from the ground up as an open source gadget, complete with open source hardware, and whose designers encourage hackers to get into the device and make it their own. He is also the author of "Hacking the Xbox", a book about reverse engineering consumer products and the social and practical issues around doing so.
bunnie is currently a Research Affiliate of the MIT Media Lab, technical advisor for several hardware startups and MAKE magazine, and shares his experiences manufacturing hardware in China through his blog. He takes what he calls a "push-and-pull" approach to open hardware. He contributes original open designs, as well as liberating closed designs. He recently released an open implementation of a man-in-the-middle attack on high-bandwidth digital content protection (HDCP), a method of copy protection used by many media outlets, which enables overlays on encrypted video without circumventing copyright controls.
The keynote, titled "Linux in the Flesh: Adventures Embedding Linux in Hardware", embraces the idea that Linux is not just for desktops and servers, but exists, in one form or another, in millions of smartphones, routers, set top boxes, and other hardware appliances that we encounter in everyday life. bunnie will share some his experiences with embedding Linux in various hardware clients, the interplay between hardware and software architecture, system planning for embedded applications, and the challenges of hardware manufacturing and building a business selling physical goods.

What’s amazing is that there was 117 million won (~USD$108,000) worth of beef sold at a 50% discount. The fine for false advertising, which is common in group buying sites as they beef up copywriting, was 8 million won (~USD7360).
Guess they’re big, but everyone’s got to play by fair rules. I wonder how many other trade commissions look into whacky copywriting in other countries.
Okay, so it turns out an interesting, demanding, and rewarding job isn’t as compatible as I’d naively hoped with all the cool things I’d like to be doing as hobbies (like, you know, blogging more than once a year, or anything substantial at all…) Thinking it’s time to see if there’s any truth in the whole fitness fanatic thing of regular exercise helping…
Electronics design has traditionally been a solo activity. Some high-end packages have a degree of collaboration using shared libraries and synchronisation tools, but Upverter is the first project I've seen that allows real-time online collaboration. Multiple engineers can be working in the same project simultaneously, and the project updates live so all participants can see changes as they happen. Now with Upverter's latest release they've extended their initial schematic tool to include PCB layout, which may just tip it over the edge to being a major contender as design tool of choice for many engineers.
Check out Upverter at www.upverter.com. I'd love to know what you think.

I put up SuperHouse episode 4 a while ago, and forgot to blog about it! Slack.
Anyway, it's up now so please check it out!
I have another 2 episodes partly filmed, and work done for a couple more after that so hopefully they'll begin coming through more regularly.
When IVT started using Scrum as a development methodology I wanted to put the power to approve or reject software releases into the hands of the product manager. Combining an Arduino-compatible board from Freetronics, a WiFi shield, the JIRA issue tracker, the Git source code management system, a custom web service, and some flashing lights, this is the result.

It’s amazing how many people I meet who got en-wikied by Wikitravel, the freely licenced worldwide travel guide founded by Evan Prodromou and Michele Ann Jenkins. I was always a bit sad that it wasn’t a Wikimedia project (once I knew there were Wikimedia projects aside from Wikipedia). I was a heavy editor in 2004 and 2005 and became an administrator in 2006, and still (well, as of yesterday) held that role on the website although I haven’t been very active since 2007.
For entirely separate reasons, I ended up keynoting Wikimania this year, which was great and terrible timing as far as wikis for travel went. Great, because it was at Wikimania that part of the discussion about founding a Wikimedia Foundation travel wiki was going on (Internet Brands owns the Wikitravel trademark and domain name), and I was told about it by one of the people active in it. Terrible, because I was so exhausted and overwhelmed after AdaCamp and my keynote that I didn’t do nearly enough at Wikimania. (The evening of the keynote, I went to my hotel at 4pm and ordered room service dinner. Thank you, room service crème brûlée, for getting me through that night.) I did meet someone who was among those spearheading the proposal to have a WMF travel wiki, but I didn’t attend the travel wiki meetups, nor log in anywhere to express an opinion among the various proposals.
It seems that what was eventually decided was to immediately import content originally written for Wikitravel into an English language version of Wikivoyage, which had already assembled a German and Italian community to create a non-commerical wiki travel guide some years back. The edit history of Wikitravel as of early August has been imported (since August, Internet Brands turned off the API access to Wikitravel changes), with further edits being made by Wikivoyagers including many former Wikitravel (and current, perhaps?) editors. Wikivoyage is in turn being imported into WMF technical infrastructure very very soon (possibly Monday US time), but I finally happened to want to do some editing last night, so I jumped the gun and joined the live version of English Wikivoyage! If you remember me from Wikitravel, say hi.
It’s already possible to use Wikimedia Commons images on Wikivoyage, for which I’m very grateful. I’ve put all the research I’ve done for my upcoming trip to SEE A TOTAL SOLAR ECLIPSE into the Solar eclipses travel article, a perfect use-case for Commons images, which has hundreds of shots of eclipses. I’ll see if I can find a good replacement for the very mediocre image from my 2006 trip to Cairns still used on that article.
I couldn’t help but overhear a conversation today. It was in an airport bus, wheeling us to our plane. The dramatis personae involve folk that are from America.
Lady: “Where do you work?”
Man: Almost apologetically states, “I work at Oracle, that big database company. Well, until I find something else to do.”
A whiff of silence in the air.
Man: “I used to work for a small company but Oracle acquired it about a year ago”
Another man: ” When does your lock up period expire? Can’t imagine you’d enjoy working there.”
Man: “Soon, real soon.” Giggles
Lady: “Well in this economy, you don’t want to be out of a job. I guess no one leaves a company before having yet another job in the line.”
Everyone nods in agreement.
What can we learn from this?
However, this would be in contrast to the hiring battle that is being faced in Silicon Valley. The FT is the latest to talk about this.
