Inspired by Yngve Svendsen’s post, I too think it makes absolute sense to congratulate Ubuntu on the 14.04 LTS release (some server notes - MySQL has a section dedicated to it). Ubuntu users have a lot of server choice today (that’s from all major MySQL ecosystem vendors):
Ubuntu’s pitch is being the cloud platform of choice, with OpenStack support. This explains why Percona XtraDB Cluster (the only shipping Galera Cluster variant — no upstream Codership release, and no MariaDB Galera Cluster) is critical infrastructure as its used widely in OpenStack deployments. 451Research estimates that the OpenStack distributions market is worth $82 million in 2014 and $119 million in 2015.
Press release had a choice quote from Percona CEO, Peter Zaitsev:
“We are very pleased that Percona XtraDB Cluster is included in Ubuntu 14.04 LTS. Many organisations that use MySQL need high availability solutions to ensure that their applications meet the expectations of their users. Percona XtraDB Cluster is an easy to use, open source solution for MySQL clustering which addresses these high availability needs. We continue to see growth in Ubuntu usage by our customers and our open source software users so we are confident that the inclusion of Percona XtraDB Cluster in Ubuntu 14.04 will help spread the adoption of cost-effective, high availability MySQL.” Peter Zaitsev, Co-Founder and CEO at Percona
With the recent Heartbleed bug, people are clearly more interested in their MariaDB/MySQL running with SSL and if they have problems. First up, you should read the advisory notes: MariaDB, Percona Server (blog), and MySQL (blog).
Next, when you install MariaDB (or a variant) you are usually dynamically linked to the OpenSSL library that the system provides. Typically on startup of MariaDB 10.0.10 on CentOS 6.5 (packages from the MariaDB repository), you can check what your status of SSL is.MariaDB [(none)]> show variables like 'have_ssl'; +---------------+----------+ | Variable_name | Value | +---------------+----------+ | have_ssl | DISABLED | +---------------+----------+ 1 row in set (0.00 sec)
This means that SSL options are compiled, but mysqld didn’t start with it. You can verify SSL is linked dynamically:ldd `which mysqld` | grep ssl libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007ff82d1b1000)
If you are running with SSL enabled (some documentation at MySQL) you will have different options naturally. You can do this via: /etc/init.d/mysql start --ssl. Output now changes:MariaDB [(none)]> show variables like 'have_ssl'; +---------------+-------+ | Variable_name | Value | +---------------+-------+ | have_ssl | YES | +---------------+-------+ 1 row in set (0.00 sec)
The value NO will be displayed if the server is not compiled with SSL support. See SSL Server System Variables for more.
I was fortunate enough to have some free time earlier today evening, and headed over to the Martin-Gropius-Bau to catch the Ai Weiwei (@aiww)exhibition titled Evidence. This is the first time I’ve seen Ai Weiwei’s work as I missed it at the Tate Modern in London a while back.
He is a modern artists. Playing around with a lot of different materials to come up with his artwork. And he makes use of the Web. I guess his claim to fame is that he’s all for freedom of speech & expression (something that’s hard to do in China – a dissident he is, if you must), and the fact that he’s a documenter of modern happenings (everyone is interested at the amazing pace of growth in China – he shows that by video recordings of highways, or driving around and recording his journey as an example).
For me, I was really moved by Zodiac Heads (Circle of Animals). I would so grab the rat, tiger and dog as examples!
China in ten years (I first went to Beijing in 2004 – it has changed a lot in a decade) has become a lot more materialistic. The car of choice used to be the Audi; it still is, but you find a lot of other luxury vehicles on the roads nowadays in Beijing. So the Han Dynasty vases painted with metallic paint from BMW & Mercedes was great for cultural insight. Culturally, the want of antiques is also high and the Table & Chest with stripped chairs was also interesting – remove 1mm sheen from Ming Dynasty furniture and they look like new. What is the purpose of antiques again?
I enjoyed his Study of Perspectives (a selection at moma) as well. He goes to famous landmarks and takes a photo with his left middle finger.
He portrays the disputed islands (between China & Japan). I loved the stools because they each tell a story (6,000 of them). I enjoyed his re-enactment of how he was held captive by the Chinese authorities for some time. It’s shocking to see how you would sleep with a light on, always be watched by security guards and have everything covered up – where you have to do your own laundry and the only thing you get are 6 hangers. Its sad to see that his studio in Shanghai was demolished at a moment’s notice – but he made artwork out of it. He showed the evidence that was confiscated (lots of laptops/video recorders/PCs).
A protest pre-demolition involved river crabs (he xie). Guess that’s the beauty of the Chinese language :)
If you get the chance to check Ai Weiwei’s work out, its well worth it and will take you a good 2 hours (read a review in The Economist). You can’t take photos inside, but you will leave with a lot of memories. If you can’t see this one in Berlin, check out a video: Ai Weiwei – Dumbass. At five minutes long, it makes my video of the week.
I was just listening This week in google #236, and they were talking about device ecosystems. The topic of smartwatches came up obviously. The first Samsung Galaxy Gear was apparently not a good seller because it had a limited app ecosystem and it was tied to just a few devices (I only know one person who has said watch, and wears it regularly).
If Apple builds an iWatch, they will tie it into the iOS ecosystem. This is why Leo Laporte the host likes the Pebble – it works with all his devices.
How many people are Leo with an iPhone and an Android phone? And whatever else is compatible with the Pebble? End users (consumers) usually have one phone. There’s nothing wrong with the iWatch to be tied into the iOS ecosystem — its an awesome ecosystem. Soon you may get cars with iOS on it (just like you can get cars with Linux on it).
The iWatch if Apple makes one will probably be compatible all the way back to the iPhone 4S. It should cover most iOS/iPhone users. And just like the apps you buy in the app store when the iPad came along (first you had iPhone only apps, with double-size; then you had separate iPad apps that would cost more; nowadays many apps are “universal” to work on both and cost the same), I expect something similar will happen with the iWatch.
That said, I like my analogue watches. I had no interest in the Pebble or the Samsung Galaxy Gear. I’d be interested to see what they do with version 2, which has Tizen (even less apps maybe?). When Apple releases an iWatch, you can be sure I’d probably buy it — I have seen things from all sides, and I like their ecosystem.

Microsoft has its third CEO in its entire history (started 1975), Satya Nadella. Some choice quotes & thoughts…
What drives me every morning and what keeps me up every night is one thing: this business is not about longevity, it’s about relevance.
Via his letter to his employees:
Our industry does not respect tradition — it only respects innovation.
Many who know me say I am also defined by my curiosity and thirst for learning. I buy more books than I can finish. I sign up for more online courses than I can complete. I fundamentally believe that if you are not learning new things, you stop doing great and useful things.
This starts with clarity of purpose and sense of mission that will lead us to imagine the impossible and deliver it. We need to prioritize innovation that is centered on our core value of empowering users and organizations to “do more.”
I truly believe that each of us must find meaning in our work. The best work happens when you know that it’s not just work, but something that will improve other people’s lives.
Not sure about this “one microsoft” idea (I hear too much of 1Malaysia), but the elements required to aspire to change the world stand strong: talent, resources, and perseverance.
Definitely an exciting time to see what Microsoft can bring to the table. Not to mention that opensource and cloud computing is pretty much everywhere these days…
News today: Genneva (gold trading company, launched by former Prime Minister Mahathir) Malaysia director charged with accepting deposits without a license.
So if you’re thinking of a Bitcoin exchange in Malaysia, think again. Bank Negara Malaysia obviously doesn’t think much of Bitcoin. How will you accept deposits without a license?
For further reading, see the BAFIA 1989, in its entirety. Once again, laws that prevent innovation.
