IEEE R10 Excom Meeting

IEEE Region 10 (Asia Pacific) Executive Committee has just carried out its annual meeting in Hongkong, 21 January 2017. This new cabinet is led by Director Prof Kukjin Chun.

I serve in this Executive Committee as the Industry Relations Coordinator for the years 2017–2017.

*Install old packages with Debian Snapshot *

:: snapshot.debian.org is a wayback machine that allows access to old packages based on dates and version numbers. It consists of all past and current packages the Debian archive provides. I found out about this service when a customer needed to use an older version of PHP, and I couldn't find a way to cleanly do this. Thanks to Debian Snapshot, it's now done & running.

I began by finding out the exact version of PHP and Apache packages that needs to be installed.

===
The client asked for PHP version 5.3, so I browsed to http://snapshot.debian.org/package/php5/

Found that the most up to date version is 5.3.10-2,
so I browsed to its folder : http://snapshot.debian.org/package/php5/5.3.10-2/

It shows date & time of 2012-02-21 04:16:01
so I added the following line to /etc/apt/sources.list :

—-
# PHP 5.3.10-2 packages
deb http://snapshot.debian.org/archive/debian/20120221T041601Z/ unstable main
—-

Note the date & time format on that line.

Now we need to install Apache version 2.22.2-1 – why this particular version?
Answer: because this is the version required by PHP 5.3.10-2 package; it will complain if any other version are installed. So yeah that's pretty easy to figure out 🙂

Using similar technique, I found out the line for Apache2 packages :

—-
# Apache 2.22.2-1 packages
deb http://snapshot.debian.org/archive/debian/20120202T040408Z/ unstable main
—-

Now let's do the installation process itself :

===========
# remove current PHP packages
sudo apt-get remove –purge `dpkg -l | grep php | grep -w 5.5 | awk '{print $2}' | xargs`
# remove current Apache packages
sudo apt-get remove –purge `dpkg -l | grep apache | grep -w 2 | awk '{print $2}' | xargs`

# update package database
apt-get update

# this is the setting required to be able to use Debian Snapshot
apt-get -o Acquire::Check-Valid-Until=false update

# now we can specify the exact version
apt-get install php5=5.3.10-2 libapache2-mod-php5=5.3.10-2 php5-cli=5.3.10-2 php5-common=5.3.10-2 php5-gd=5.3.10-2 php5-mcrypt=5.3.10-2 php5-mysql=5.3.10-2 php5-pgsql=5.3.10-2 apache2=2.2.22-1 apache2-mpm-prefork=2.2.22-1 apache2-suexec=2.2.22-1 apache2-utils=2.2.22-1 apache2.2-common=2.2.22-1 apache2.2-bin=2.2.22-1

/etc/init.d/apache2 restart
===========

If the commands does not work, maybe it's formatting problem – you can refer instead to my Pastebin here : http://pastebin.com/r2qBtbs4

Hope you find these useful (y)

Southeast Asia startup continued to attract investors, thanks to Grab, Go-Jek, Tokopedia

Gojek

Southeast Asia startup looks promising.  At least, it’s indicated by total funding in the region. According to TechInAsia, Singapore and Indonesia continued to attract more fundings.

However, many startups that have undisclosed investments also show that the tally could have been bigger.

Southeast Asia continued to attract investors, who might have been looking for new growth opportunities. Its performance bucks the slowdown seen in India in 2016, and the big drop-off in China in the latter half of the year.

Also, while some startups might have felt a freeze as money was not flowing as freely as in years before, funding was always available for the truly robust ones. Prominent names like Grab, Go-Jek, Garena, and Tokopedia managed to bag yet more funding as they ramped up operations.

Menertawakan Sains

SSaya suka komedi. Banyak hal yang dapat dipelajari dari komedi. Saya belajar bahasa Inggris melalui komedi. Demikian pula, ada banyak cerita sejarah yang saya pelajari dari komedi juga. Sains? Matematika? Rekayasa? Semua ini dengan lawakan? Wah ini baru menarik.

Pagi hari di awal tahun 2017 ini saya membuka internet. Serius. Sehabis Subuh, sebelum matahari terbit saya membuka internet. Entah kenapa, terbuka YouTube. Yang terpampang di layar saya ada berbagai pelawak, mulai dari Johnny Carson, Jonathan Winters, dan kemudian Robin Williams. Eh, ternyata salah satunya menunjuk ke video ini.

Nampaknya ini adalah sebuah acara wawancara tentang Matematika dengan pelawak Steve Martin. Entah kenapa, Steve mengajak pelawak Robin Williams ke atas panggung. Mungkin dia tahu bahwa Robin Williams lebih tahu tentang sains (Matematika dan Fisika) lebih dari dia. Maka terjadilah berbagai adegan lucu di video itu. (Videonya dipotong menjadi beberapa video, masing-masing 10 menitan.) Gak bisa berhenti nonton video ini. Aje gile busyet dah.

Saya baru tahu bahwa Robin Williams itu ternyata cerdas banget! Dia banyak membaca dan mengerti banyak hal. Silahkan lihat videonya. Ada banyak lawakan yang terkait dengan matematika (dan fisika). Serius! Edan pisan!

Lawakan jenis ini – yang membutuhkan pendengar untuk mikir – merupakan jenis yang saya sukai. Ah, ternyata bisa juga menggabungkan lawakan dengan sains. Ini merupakan dorongan positif buat saya agar terus dapat menjelaskan konsep yang susah dengan lawakan.

Belajar ah … (dan banyak membaca tentunya).
