Following my previous post on the launch, I just rolled Ubuntu 14.04 LTS on an Amazon EC2 t1.micro instance (not something you expect to run a database server on, for sure – 1 vCPU, 0.613GiB RAM). If you do an apt-cache search mysql you get 435 return result sets with the default configuration (trusty: main & universe).
If you do apt-get install mysql-server, you get MySQL 5.5. You enter the password of choice, and before you know it, MySQL is installed (a SELECT VERSION() will return 5.5.35-1ubuntu1).
Next you decide to install MariaDB. I run an apt-get install mariadb-server. It pulls in libjemalloc (for TokuDB) and I expect future releases to ship this engine by default. You enter the password, and you get a new message (as pictured).
I verify my test database that I created exists. It does. A SELECT VERSION() returns 5.5.36-MariaDB-1. The innodb_version returns 5.5.36-MariaDB-33.0.
I’m curious about MySQL 5.6 now. So I run apt-get install mysql-server-5.6. Not so straightforward.start: Job failed to start invoke-rc.d: initscript mysql, action "start" failed. dpkg: error processing package mysql-server-5.6 (--configure): subprocess installed post-installation script returned error exit status 1 Setting up mysql-common-5.6 (5.6.16-1~exp1) ... Processing triggers for libc-bin (2.19-0ubuntu6) ... Errors were encountered while processing: mysql-server-5.6 E: Sub-process /usr/bin/dpkg returned an error code (1)
Looks like MySQL 5.6 is more memory hungry… I edited /etc/mysql/my.cnf to ensure that innodb_buffer_pool_size = 64M (I increased this to 128M and it worked too) was set (there was nothing in the default config) and re-ran apt-get install mysql-server-5.6 and it started. My test database was still around ;-)
I wanted to make sure that MySQL 5.6 isn’t more memory hungry just on that instance so I created yet another clean t1.micro instance and did an apt-get install mysql-server-5.6. Same error. Reported lp#1311387.
Nothing to report in particular about Percona – 5.5.34 Percona XtraDB Cluster (GPL), Release 31.1 (Ubuntu), wsrep_25.9.rXXXX. One thing is for sure – if you’re playing around with the ecosystem, installs and upgrades aren’t exactly straightforward.
As one decompresses from the active month that April brings to the MySQL ecosystem, its worth noting that I received a MySQL Community Award – Community Contributor of the Year 2014 award at the Percona Live MySQL Conference & Expo 2014 in Santa Clara. I was extremely happy and thankful to receive such an award and I still am. Thank you MySQL Community.
My reason for winning, now immortalised:
Colin’s list of service to the MySQL Community goes back almost 10 years. He was a community engineer starting in 2005, chaired some of the O’Reilly MySQL conferences, ran the MySQL projects for Google Summer of Code. As a partner and Chief Evangelist for Monty program, he continues to promote and grow the MySQL ecosystem. Though it’s his job, he goes above and beyond, driven by his passion for open source and MySQL.
I was amongst very good company (congratulations to all the winners). Thank you to whom nominated me, and to the committee for vetting it. Frederic wrote a nice post with a little selfie. Tomas expresses heartfelt thanks from Oracle.
Anyway, not to rest on one’s laurels – while its great to be given an award after years of being involved in the community, I will work harder in the coming months to make things better in any way I can. Thank you again, MySQL Community.
Beautiful designed apps should be conduits for web services. Or provide some form of “desktop” capability. Sync is important.
You know him from Tumblr, Instapaper, The Magazine, and (coming soon) Overcast.
You may think of Marco as an iOS developer — but every single one of those apps is a web service.
This thought process works very well with a presentation John Gruber gave at Web 2.0 Expo NY – watch the 10 minute video on Apple and the Open Web. He describes Apple as a “ht” company: they’ve embraced HTML and HTTP.
I look at my iPhone and think to myself what apps I use (i.e. have an icon on my screen) that are web apps:
What isn’t a web app? Photos (though there is an iCloud Sync that I don’t use – I prefer it going to Dropbox), Camera, most of Apple’s standard apps (of course, FaceTime, Notes, Calendar – they all sync), DocScanner (syncs to Dropbox, but has no web app behind it), Snapseed, Camera+, 360 (has a web component though I never use it). Music/Podcasts theoretically sync with the web, but again, not my use case. I don’t consider Google Authenticator a web app either though I use it in conjunction with the web. Messages has iMessage but there isn’t a web interface (yet?).
We can argue that the messaging apps aren’t really web services. KakaoTalk/Line have desktop clients. Whatsapp is notoriously mobile-only. Viber/WeChat seem to be mobile only for me. Telegram leads the way by having a nice Chrome browser plugin. Skype is a desktop app.
That makes the majority of my apps that I use, really, web apps. My phone is a conduit to the Internet. This is why I consume data and WiFi.
My iPad is not much different – I use it a lot more for reading, and that includes the FT (fully HTML5 web + mobile app), WSJ, NYTimes, New Yorker, The Economist. OK, there’s GoodReader, iBooks, Zinio for offline reading too, a lot more magazines, and some office software – the iWork suite (which syncs to iCloud). A cool app like Penultimate (now free after Evernote purchased them – again syncs online).
This is the success metric for an app. No point building an application to have a F1 racing timetable (I get that from F1.com or a simple Google search). No point building an application that collects Malay proverbs (I can search for that if I was interested; or if it was the English context, I’d just look up wikiquote).
Games seem to be an exception to this, but as I have never played games and don’t intend to start (I don’t grok the mind of a gamer, sorry), I’ll pass on overall commentary.
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.
