Mobile World Congress 2010 – Mark Dennehy

Mar 02, 2010

Two years ago while I was working at dotMobi, I was one of the programmers working on the DeviceAtlas project, which launched at Mobile World Congress 2008. At the time, it was the largest launch I?d been involved in and it was quite a ride towards the end ? when you?re launching to 60,000 people [...]

BuddyPress for One (and All!)

Feb 26, 2010

Back in April of last year, Matt posted here on the dev blog about the release of BuddyPress 1.0, a plugin that adds a social networking layer to an installation of WordPress MU. Many people were excited about the idea, but were unable to experiment with BuddyPress because they ran single installations of WordPress rather [...]

Charlie Anthony: Mencoba Mode Jendela Tunggal pada GIMP

Feb 14, 2010


tanya siapa?

GIMP dengan mode jendela tunggal

Dulu sebelum saya mengenal Ubuntu, saya sering menggunakan aplikasi Paint.NET atau Adobe Photoshop (versi bajakan tentunya ^^) untuk menyunting gambar. Nah, saat saya menggunakan Ubuntu, saya merasa kurang nyaman menggunakan aplikasi penyunting gambar bawaannya, yaitu GIMP. Mengapa? Karena pengaturan jendela di GIMP agak kacau (menurut saya), tidak seperti pada Paint.NET atau Photoshop yang menggunakan gaya single window (jendela tunggal).

Nah, beberapa minggu lalu saya membaca sebuah kabar bahwa GIMP akan mengimplementasikan mode jendela tunggal pada versi 2.8 nanti. Ya, para tim pengembang dan desainer tampilan sedang melakukan diskusi intensif mengenai hal ini. Karena penasaran, akhirnya saya mencoba melakukan instalasi GIMP versi 2.7 beta dari sebuah repositori PPA milik matthaeus123.

Setelah instalasi (atau lebih tepatnya upgrade ^^) selesai, saya langsung membuka GIMP. Saya disambut dengan sebuah tampilan splash-screen GIMP baru. Hmm ? tampilannya masih tetap multi-jendela seperti GIMP 2.6. Setelah beberapa saat mencari-cari opsi atau konfigurasi untuk mengatur tampilan, akhirnya saya menemukan opsi untuk mode jendela tunggal pada menu Windows. Saya aktifkan mode tersebut dan ? VOILA! Jendela toolbar langsung merapat ke kiri, sedangkan jendela Layers dan Brushes merapat ke kanan. Gambar-gambar yang saya buka juga tertata dengan sistem tabbed. Wow! Akhirnya saya bisa menikmati mode jendela tunggal pada GIMP!! ^^

Namun seperti rilis beta pada aplikasi lain, GIMP 2.7 ini juga masih memiliki sejumlah bug. Beberapa yang saya rasakan adalah kinerja aplikasi yang sedikit lebih lambat pada mode jendela tunggal, dan pengaturan jendela yang terkadang kacau saat saya menonaktifkan mode jendela tunggal. Bagi anda yang tertarik mencobanya, pastikan anda tahu apa yang anda lakukan karena GIMP 2.7 ini bukan versi stabil. Kalau anda ingin “main aman”, silakan tunggu rilis stabil GIMP 2.8 nanti. ^^

Virtio: An I/O virtualization framework for Linux

Feb 05, 2010

pWith all the virtualization schemes running on top of Linux, how do they exploit the underlying kernel for I/O virtualization? The answer is virtio, which provides an efficient abstraction for hypervisors and a common set of I/O virtualization drivers. Discover virtio, and learn why Linux will soon be the hypervisor of choice./p

Friendlist Graph Module for Drupal

Jan 29, 2010

At DrupalSouth 2010 (Wellington) after LCA2010, Peter and I implemented a Drupal module as a practical example of how the OQGRAPH engine can be used to enable social networking trickery in any website. The friendlist_graph module (available from GitHub) extends friendlist, which implements basic functionality of friends (2-way) and fans (1-way) for Drupal users.
The friendlist_graph module transposes the friendlist data using an OQGRAPH table, allowing you to query it in new and interesting ways. By adding some extra Drupal Views, it allows you to play Six Degrees of Kevin Bacon with your Drupal users or find out how two arbitrary users are connected. It can find a path of arbitrary length near-instantly. Previously, you#8217;d just avoid doing any such thing as it#8217;s somewhere between impossible/limited/slow/painful in a regular relational schema.
Now think beyond: retrieve/share connections using Open Social, FOAF, Twitter/Identi.ca, logins with OpenID, and you #8220;instantly#8221; get a very functional social networking enabled site that does not rely on localised critical mass!
We tested with about a million users in Drupal (and approx 3.5 million random connections), which worked fine #8211; the later demo at the DrupalSouth stuffed up because I hadn#8217;t given the demo VM sufficient memory.
Naturally, you could do the same in Joomla! or another CMS or any site for that matter, we just happened to be at DrupalSouth so a Drupal module was the obvious choice. Take a peek at the code, it#8217;s pretty trivial. Just make sure you run a version of MySQL that has the OQGRAPH engine, for instance 5.0.87-d10 (Sail edition!) from OurDelta.

New OLAP Wikistat benchmark: Introduction and call for feedbacks

Jan 29, 2010

I’ve seen my posts on Ontime Air Traffics and Star Schema Benchmark got a lot of interest
(links:

http://www.mysqlperformanceblog.com/2010/01/07/star-schema-bechmark-infobright-infinidb-and-luciddb/

http://www.mysqlperformanceblog.com/2009/10/02/analyzing-air-traffic-performance-with-infobright-and-monetdb/

http://www.mysqlperformanceblog.com/2009/10/26/air-traffic-queries-in-luciddb/

http://www.mysqlperformanceblog.com/2009/11/02/air-traffic-queries-in-infinidb-early-alpha/

).
However benchmarks by itself did not cover all cases I would want, so I was thinking about better scenario. The biggest problem is to get real big enough dataset, and I thank to Bradley C. Kuszmaul, he pointed me on Wikipedia statistics on access to wikipedia pages, and thank to Domas, who made stats accessible. Link to the archives: http://dammit.lt/wikistats/archive/ or the original Domas’s announcement .
Although the table does not have very much different information, I think it is good enough to represent cases you can face in Web application ( log processing, page visits, clickstream, etc).
I made some efforts to normalize data to have model in classic star schema and prepared queries that could be run on proposed dataset (John Sichi, lead of LucidDB helped me to draft some queries).
You can see details on our Percona Wikistat benchmark Wiki.
I have next goals with proposed benchmark:

Compare engines in OLAP queries for planning, predicting growth, analyzing access patterns to wiki pages, draw trends.
Compare engines in statistical queries for end users, which can be executed in real-time. I.e. How many times that or another page was accessed yesterday vs today.
Understand specific features and characteristic of each engine.
Compare throughput on simple queries (queries and scenario to be drafted yet)
Check ability to load data and serve queries at the same time ( availability during data load ) (queries and scenario to be drafted yet)

So in proposed schema I have four tables:
pagestat (fact table), and pages, datesinfo, projects (dimensions tables).
Dimensions tables are supposed to be static and not changed, and we can change datasize
by varying amount of months loaded into fact table (so this is scale factor).
EEM diagram

( made with MySQL Workbench )
In current dataset, which you can download from Amazon snapshot (name: ?percona-wikistat?, ID:snap-a5f9bacc) we have:

Table pages: 724.550.811 rows. data size: 40476M
Table datesinfo: 9624 rows, one entry represents 1 hour
Table projects: 2025 rows
Table pagestats
Data for 2009-06: # 3.453.013.109 rows / size 68352M
Data for 2009-07: # 3.442.375.618 rows / szie 68152M

So with two months of stats we have about 172GB of data with about 7 billion rows in fact table.
Example of query ( again, full list on Benchmark Wiki)
PLAIN TEXT
SQL:

SELECT project, sum#40;page_count#41; sm

nbsp;FROM pagestat

nbsp; nbsp;JOIN datesinfo di ON #40; di.id=date_id #41;

nbsp; nbsp;JOIN projects p ONnbsp; #40;p.id=project_id #41;

nbsp;WHERE di.calmonth=7 AND di.calyear=2009

nbsp;GROUP BY project

nbsp;ORDER BY sm DESC

nbsp;LIMIT 20;

I am going to load data and run queries against available engines:

MySQL MyISAM / InnoDB (to have reference results)
InfoBright
InfiniDB
MonetDB
LucidDB
Greenplum

and I will report my results ( so stay with MySQLPerformanceBlog )
I’d like also to test also Paraccel, Vertica and KickFire systems, but I do not have access to.
I welcome your feedback on the benchmark, and what else you would like to see here.

Menginstall MySQL Secara Manual di Linux

Jan 19, 2010

Pada episode OpenScreen kali ini saya membahas tentang cara menginstall MySQL di Linux secara manual. Jadi tidak menggunakan apt-get atau yum secara otomatis, sehingga kita menginstall benar-benar secara manual tanpa bantuan sistem operasi linux.
