The mobile phone required update to the latest version of Android operating system. This Korean model of LG G3 didn't offer Over the Air (OTA) updates.</p><p>The first step in the update process is to connect the model phone to the computer using USB cable. However the standard Android '<a href="https://developer.android.com/studio/run/win-usb.html">Google USB Drivers</a>' didn't work. After some searching I found that LG Universal Mobile Drivers from <a href="http://www.lg.com/us/support/product-help/CT10000025-20150179827560-downloaded-apps" title="LG Driver download">LG support site</a>.</p><p>Next I used the <a href="http://www.lg.com/us/support/product-help/CT10000026-20150108669720">LG Mobile Support Tool</a> program on my computer to start updates. This model is not supported by <a href="http://www.lg.com/us/support/product-help/CT10000026-20150108669720">LG Bridge Software</a>. After couple of updates I managed to upgrade the mobile phone to Android 6.0 Marshmellow. Each update requires a download of 1GB update and you need to wait for the phone to reboot and optimize all the Android applications.</p><p>There was one glitch in the upgrade. Had to restart an upgrade when I faced 'Upgrade stopped due to an error' message.</p><p>Here rather straight forward way to upgrade the phone to latest Android 6.0 (Marshmellow):</p><p><ul><li>Download <a href="http://www.lg.com/us/support/product-help/CT10000025-20150179827560-downloaded-apps">LG Universal Mobile Drivers</a>.</li>
<li>Connect the phone and put it in MTP mode.</li>
<li>Download <a href="http://www.lg.com/us/support/product-help/CT10000025-20150179827560-downloaded-apps">LG Mobile Support Tool</a>.</li>
<li>Follow instructions on the screen. Each upgrade download is about 1GB</li>

But it is recommended to deploy GNU/Linux Continuous Integration (CI) server using these instructions.</p><pre><code>
# Add Debian package repository of Jenkins GPG key:
$ wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
# Then add the following entry to your/etc/apt/sources.list:
$ echo deb http://pkg.jenkins.io/debian-stable binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list
# Update your local package index:
$ sudo apt-get update
# Install Jenkis server:
$ sudo apt-get install jenkins
# Start Jenkins service and verify its status:
$ sudo systemctl start jenkins
$ sudo systemctl status jenkins
# Open http://localhost:8080 in your browser and copy paste in the secret password.
# Follow the on screen instructions to create Jenkins server admin account
$ sudo cat /var/lib/jenkins/secrets/initialAdminPassword
# Open the ports 8080 through your firewall:
$ sudo ufw allow 8080
$ sudo ufw status
</code>
</pre><p>Adding a <a href="https://playingwithsid.blogspot.com/2014/12/server-monitoring-with-monit-tutorial.html" title="Monit Server">monit</a> service to monitor the Jenkins server is a good idea. Monit ensures that Jenkins server is restarted automatically when it crashes.</p><code><br />
<pre># Create a Jenkins monitoring file with following lines with:
$ sudo nano /etc/monit/conf.d/jenkins
check process jenkins with pidfile /var/run/jenkins/jenkins.pid
start program = "/etc/init.d/jenkins start"
stop program = "/etc/init.d/jenkins stop"
</code>
</pre><p>Also you'll need to <a href="https://www.linode.com/docs/email/exim/sendonly-mail-server-with-exim-on-debian-6-squeeze">configure mail server</a> to send Jenkins build reports.</p>Anonymoushttp://www.blogger.com/profile/06093157516997210224noreply@blogger.com0Phnom Penh, Cambodia11.5448729 104.8921668000000411.0471024 104.24671980000004 12.0426434 105.53761380000005tag:blogger.com,1999:blog-3970910572020526646.post-27057548034244379082017-09-06T17:19:00.000+07:002017-09-06T17:19:28.263+07:00ProDisk Mini White Balance Card <p>I picked up a <a href="http://www.fotopl.cz/zarizeni-prodisk-p800.html

I have a fond memory of reading the magazine sitting on the windowsill waiting for my parents to return home. After two decades I visited the store that sold these English language magazine published in Russia, there were no trace of any magazines. Sometimes you would see this magazines in secondhand book stores but that is very rare now.</p><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-0ADgHcy1OQg/T3XJWo9ja9I/AAAAAAAAAGY/x12iSnDRRQo/s1600/misha-magazines.jpg" imageanchor="1" style="margin-left:1em; margin-right:1em"><img border="0" height="205" width="320" src="https://1.bp.blogspot.com/-0ADgHcy1OQg/T3XJWo9ja9I/AAAAAAAAAGY/x12iSnDRRQo/s320/misha-magazines.jpg" alt=""></a></div><p>Searching through the Internet, I found this blogger share a digital copy of the magazine. He writes in this post titled <a href="http://saintelmosfire.wordpress.com/2007/12/11/20/">Remembering Misha </a><br />
<blockquote><p>"Back in the 1980s, Misha (which translates to bear in Russian) was the most popular children’s magazine in India published in English. Within its glossy pages, you were treated to folk tales, science fiction, riddles, photographs,pen pal sections, puzzles and illustrations. As an added bonus, it smelled awfully good."</p><p>"Unfortunately the collapse of the USSR spelled death for many Soviet publishing houses (Raduga, Mir and others) and Misha soon became extinct."</p></blockquote><div align="center"><div data-configid="0/2441852" style="width:525px; height:340px;" class="issuuembed"></div><script type="text/javascript" src="//e.issuu.com/embed.js" async="true"></script><br />
</div><p>According to few sources, the magazine continued to publish in Russian for long time after the collapse of the USSR. I reached out to the former editor of the magazine for confirmation. <br />

(Video)<p>Just watched yet another <a href="https://en.wikipedia.org/wiki/Cats_and_the_Internet">funny cat video on Internet</a>. I wonder when our fascination with funny cat videos began. It turns out that the earliest cat video dates back to the birth of motion pictures. Thomas Edison the consummate commercializer of his innovations made earliest movies to promote the motion picture camera "<a href="https://en.wikipedia.org/wiki/Thomas_Edison#Motion_pictures">Kinetograph</a>. After the initial popularity of these penny movies (penny was the cost of ticket) of humans moving, dancing and sneezing waned. He moved on to man's furry friends.

Growing up I tried to learn electronics by reading radio repair guides and engineering textbooks in vain. Always got stumped by mathematics and dry tone of the books. The advent of Arduino changed all that. Now it is easier to learn electronics without getting bogged down by technicalities and focus on making something fun!.</p><p>The '<a href="http://store-usa.arduino.cc/products/arduino-starter-kit">Arduino Starter Kit</a>' is suitable for self-learning Arduino with simple fun projects. Lot of attention has given to developing course material and overall ascetic design of this kit. The Starter kit comes full set of high quality electronic components and a 170 page project guide book. The ready to use cardboard cutouts makes it great activity kit that could used by parent and the child.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-4pzO2KtY04U/V8f-ZukwtJI/AAAAAAAABbg/fra0gzJyjlcimxraaoPlZiBqoVaIAQZngCLcB/s1600/Arduino-Starter-Kit.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://1.bp.blogspot.com/-4pzO2KtY04U/V8f-ZukwtJI/AAAAAAAABbg/fra0gzJyjlcimxraaoPlZiBqoVaIAQZngCLcB/s320/Arduino-Starter-Kit.jpg" width="320" height="157" alt="Arduino Starter Kit components"/></a></div><p>The project guide book explains all the basic electronic components, their function and use in a simple lucid manager. The quality<br />
of the book and its design is very tasteful. The programming code is explained in full detail. Further online resources are also<br />
provided to aid learning.</p><p>Here is complete list of the components that are bundled in the kit.<br/> <br />
<ul><li>1 Projects Book</li>

There are numerous posts about this problem but very few solutions. <p><pre><code>

</code>
</pre><h2>Solution for Blender missing library</h2><p>Let me share what worked for me. Let's try to locate and add the library to ldconf path.</p><pre><code>
# Install the libavcodec-extra package using apt-get package manager.
$ sudo apt-get install libavcodec-extra-56
# Verify the location of libavcodec.so.54 file path.
$locate libavcodec.so
/usr/lib/x86_64-linux-gnu/libavcodec.so
/usr/lib/x86_64-linux-gnu/libavcodec.so.56
/usr/lib/x86_64-linux-gnu/libavcodec.so.56.1.0
# Create a new ldconfig file with proper path to the shared library.
$ sudo nano /etc/ld.so.conf.d/blender.conf
# Add the following line in the file.
/usr/lib/x86_64-linux-gnu/
# Rerun ldconf
$ sudo ldconf
# Start blender normally.

I believe the values of open design, sharing of technical know-how and healthy dose of hubris defines Shenzhai culture. It drives the innovative product design in Shenzhen. Today this culture of design and easy availability of manufacturing facilities is attracting designers, makers, hackers and entrepreneurs.</p><p>I hope you'll enjoy this documentary and hopeful make your way to Shenzhen in near future.</p><br />

Web browsers now natively support VR applications using <a href="https://mozvr.com/">WebVR</a> JavaScript API. We can now design virtual worlds using markup language and connect them to devices such as Oculus Rift and Leap motion controller using just a web browser.</p><p>To hit the ground running with WebVR. I started an experiment to capture Hackerspace Phnom Penh using <a href="https://play.google.com/store/apps/details?id=com.google.vr.cyclops&hl=en">Google Cardboard camera app</a> and display it using <a href="https://aframe.io/">A-Frame</a> framework. The Google Cardboard camera photosphere is not supported by A-Frame. But the positive responses to my query encouraged me to try an hack using A-Frame <a href="https://aframe.io/examples/showcase/sky/">Panorama</a> component.</p><blockquote class="twitter-tweet" data-lang="en"><p lang="en" dir="ltr">Is it possible to embed Google cardboard camera image capture in a <a href="https://twitter.com/aframevr">@aframevr</a> powered site?</p>— Arky (@playingwithsid) <a href="https://twitter.com/playingwithsid/status/677315889335697408">December 17, 2015</a></blockquote><script async src="//platform.twitter.com/widgets.js" charset="utf-8"></script><br />
<p>And it works. Almost I had to tweak the scale setting a bit to try get the perspective right but it does work. The ideal solution is to create a <a href="https://aframe.io/docs/0.2.0/core/component.html">A-Frame custom component</a>, that I leave it for more skilled people.</p><p>The markup needed for this demo is simple, you can achieve this with one line. </p><code><br />
<pre><a-scene>
<a-sky src="img/hackerspace.vr.jpg" radius="2400" scale="2 1 2"> </a-sky>
</a-scene>
</pre></code><br />
<p>You can see the demo on <a href="https://www.youtube.com/embed/_KvNbBuQAWY">Youtube</a> or visit this <a href="http://arky.github.io/hackerspace-vr/">webpage</a> in an compatible web browser. <br />

I had been waiting for this news for a long time. I quickly deployed Let's Encrypt on my staging server to learn how this technology works. The deployment process is painless and very straight forward. The certificates needs to renewed every 3 months, the Let's Encrypt client does this automatically. Thank you Jerome and Ryan for all your help!.</p><p>At the time of writing this blog post, Let's Encrypt client was not available for <a href="https://letsencrypt.readthedocs.org/en/latest/using.html#nginx">Ngnix server</a>. So I am using the <a href="https://letsencrypt.readthedocs.org/en/latest/using.html#manual">manual method</a> to obtain the SSL certificate here. Please read the latest <a href="https://letsencrypt.readthedocs.org">docs</a> for additional information.</p><pre><code>
# Check out the let's encrypt source code
$ git clone https://github.com/letsencrypt/letsencrypt
# Stop the Nginx server, we need the client to bind to port 80.
$ sudo service nginx stop
# Start the let's encrypt client and follow the instructions on screen. You need to provide an email address.
$ sudo ./letsencrypt-auto --server https://acme-v01.api.letsencrypt.org/directory certonly --domains staging.example.org
IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/staging.example.org/fullchain.pem. Your
cert will expire on 2016-01-02. To obtain a new version of the
certificate in the future, simply run Let's Encrypt again.
- If like Let's Encrypt, please consider supporting our work by:
Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate
Donating to EFF: https://eff.org/donate-le
# Edit the Nginix config to point to generated certificates.
$ sudo nano /etc/nginx/sites-enabled/staging.example.org

Salla Mäkinen had been talking about composting kitchen waste. One afternoon I decided to try to make DIY compost bin with Salla's help. The design is simple and easy to make in less than an hour.</p><p>We head down to hardware shops along the Russian Market area to buy used paint buckets. The first bucket with a lid holds the composting material and the second one collects the drainage seeping from the compost. Salla and I drilled lot of small holes in the first bucket. Then put in four large bolts to hold the bucket up, this seems better design than putting a brick at the bottom. That's it. Now the compost bins are ready for my kitchen waste.</p><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-1UubOyMiBWc/VkMi7swIu4I/AAAAAAAABFQ/y_ArfTsIIog/s1600/Salla-DIY-BioDigesters1.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://2.bp.blogspot.com/-1UubOyMiBWc/VkMi7swIu4I/AAAAAAAABFQ/y_ArfTsIIog/s320/Salla-DIY-BioDigesters1.jpg" /></a></div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-Ufq0Fnq4VLc/VkMi7X2kcsI/AAAAAAAABFM/PH2-SwIVV9g/s1600/Salla-DIY-BioDigesters2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-Ufq0Fnq4VLc/VkMi7X2kcsI/AAAAAAAABFM/PH2-SwIVV9g/s320/Salla-DIY-BioDigesters2.jpg" /></a></div><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-2I7Rc1Ym0x4/VkMi7Yu18NI/AAAAAAAABFI/dXFOUD9VpIM/s1600/Salla-DIY-BioDigesters3.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-2I7Rc1Ym0x4/VkMi7Yu18NI/AAAAAAAABFI/dXFOUD9VpIM/s320/Salla-DIY-BioDigesters3.jpg" /></a></div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-N3FgD8oQq0A/VkMi8shImsI/AAAAAAAABFU/ssmdqeDpU_8/s1600/Salla-DIY-BioDigesters4.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-N3FgD8oQq0A/VkMi8shImsI/AAAAAAAABFU/ssmdqeDpU_8/s320/Salla-DIY-BioDigesters4.jpg" /></a></div><p>We need to improve this design to make it easy to churn the compost for aeration.

At times the technology solutions were complex; at other times they were off-the-shelf consumer electronics. In this post, I'll share an example that added value to the <a href="http://ngocentre.org.vn/">NGO Resource Centre</a> in Hanoi, Vietnam. </p><p>NGO Resource Centre needed a solution to improve the audio quality of teleconferences. People connected to the NGO Resource centre's working group meetings using Skype from all over Vietnam and the world. We need an affordable conference speakerphone, non-profits often have very limited budget for technology. This device had to be simple to use, without the need for additional training and able to capture voice of half a dozen people sitting around a large conference table. </p><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-iKMuUuUvtRo/VkMmNxy2lLI/AAAAAAAABFw/gNFfL_B1tGU/s1600/Blog-C100-Conference-Speaker-phone.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://3.bp.blogspot.com/-iKMuUuUvtRo/VkMmNxy2lLI/AAAAAAAABFw/gNFfL_B1tGU/s320/Blog-C100-Conference-Speaker-phone.jpg" alt="C100 Conference Speaker Phone"/></a></div><p>First I considered using regular Bluetooth hands free speakerphone, however they are really designed for use of single person and the quality of microphone is not suitable for conference use. After some research, I found the <a href="http://www.polycom.com/products-services/voice/desktop-solutions/pc-speakerphones/CommunicatorC100.html ">Polycom Communicator C100</a> that fitted the bill perfectly. We were able to buy this device locally in Hanoi.The feedback from NGO Resource Centre staff and the participants of the teleconferences was very positive. The audio quality was really great. The dual microphones provide great audio quality and speaker volume was loud yet clear. The Polycom C100 plugs into your computer and works with Skype software client on the computer out of the box.</p><p>When providing technology solutions, it is very important that the technology should make one's life easier not challenging.

One morning Jack discovered his Hornit bike horn was suddenly all quiet. He opened the casing at Hackerspace Phnom Penh to find the over sized resonator(not quite sure if it one) had broken off. Perhaps the designers could have reinforcing this component with some glue or something instead of relying on strength of soldering alone. After all this is meant to be mounted on a bike and should withstand bumpy rides and vibrations. This is a very good example of technology world as built.</p><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-PygSpPRVcuU/VjnGD7eYvII/AAAAAAAABDk/XNo3iz6XtAA/s1600/HornIT-is-silent.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-PygSpPRVcuU/VjnGD7eYvII/AAAAAAAABDk/XNo3iz6XtAA/s320/HornIT-is-silent.jpg" alt="Broken resonator in Hornit bike horn"/></a></div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-dbez2NfBmBI/VjnGXcdc4VI/AAAAAAAABDs/kNBsVO4aU90/s1600/Broken-Resonator.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-dbez2NfBmBI/VjnGXcdc4VI/AAAAAAAABDs/kNBsVO4aU90/s320/Broken-Resonator.jpg" alt="This component had broken off due during a ride" /></a></div><p><a href="https://www.facebook.com/groups/hackerspacepp">Hackerspace Phnom Penh</a>'s Jack, Leo managed to solder it back on.

Head into town on the <a href="https://www.limousinebus.co.jp/en/">airport bus</a> to Shinjuiku's <a href="http://www.yodobashi.com">Yodobashi Camera</a>. The store is situated few hundred feet from the Shinjiku station airport bus stop. The Yodobashi camera store is photographers delight. The staff speak good English and are very helpful. It might be a good idea to first check the Yodobashi website to see they have the products you want in stock.</p><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-jCv6c9ncr9A/VjmrGgI3kmI/AAAAAAAABC8/r2SgkQxlT8U/s1600/76493117_f88c2a5608_z.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-jCv6c9ncr9A/VjmrGgI3kmI/AAAAAAAABC8/r2SgkQxlT8U/s320/76493117_f88c2a5608_z.jpg" /></a><p><small>Photo credit <a href="https://www.flickr.com/photos/nodoca/76493117/">Daisuke Matsumura</small></a></p></div><p>The store offers VAT discount for foreign travelers and further discount on purchases using Visa cards.

We organized a saturday afternoon workshop for the coding club members of local international school. The parents who brought the kids were just as excited about the 3D printing technology.</p><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-zln5Chh4ynM/VjmyqzsSNsI/AAAAAAAABDQ/MXrUV8MqDpo/s1600/Teaching-3D-printing-Cambodia.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-zln5Chh4ynM/VjmyqzsSNsI/AAAAAAAABDQ/MXrUV8MqDpo/s320/Teaching-3D-printing-Cambodia.jpg" alt="Teaching 3D printing at Hackerspace Phnom Penh" /></a><p><small>Photo Credit: <a href="https://instagram.com/p/3lNlViK73t/?taken-by=pescapop">Akira</a></small></p></div><p>The workshop started with <a href="http://www.stemphnompenh.com/">Leo Jofeh</a> walking the kids through the basics of 3D printing technology. The <a href="https://en.wikipedia.org/wiki/MakerBot_Industries#Cupcake_CNC">Makerbot Cupcake CNC</a> was used to show various parts of 3D printing machine. The DIY model of the Cupcake CNC 3D printer makes it easy to see all the parts unlike the more recent models of the 3D printers.</p><p>Next we brought in the modern <a href="https://www.lulzbot.com/products/lulzbot-mini-3d-printer">Lulzbot Mini 3D</a> printer and did a quick test print of small object from <a href="http://thingiverse.com/">Thingiverse.com</a> to show the whole 3D printing process. The kids were already bubbling with ideas for building model tanks to full scale super hero characters. However we suggested something simpler that doesn't take hours of print time. The code club members were already familiar with the <a href="http://www.sketchup.com/">Google Sketchup</a> program. So they quickly started creating drawing of comic characters and creating custom currency coins. With a <a href="https://extensions.sketchup.com/en/content/sketchup-stl">Sketchup STL export plugin</a> they could export the drawings into a 3D printable STL file.</p><p>Leo collected these STL files and added to them the <a href="https://www.lulzbot.com/cura">Cura printing software</a> with minor changes. The kids and the parents were totally engrossed all throughout the workshop. Indeed 3D printing unleashes your inner tool maker in everyone.</p><p>The workshop was a learning experience for us. Next we are going to expand the program to cover more schools and with few working templates that kids and the parents can work-together.</p><p>If you want to help or get involved please get in touch with us at <a href="https://www.facebook.com/groups/hackerspacepp">facebook.com/groups/hackerspacepp</a>.</p>Anonymoushttp://www.blogger.com/profile/06093157516997210224noreply@blogger.com1tag:blogger.com,1999:blog-3970910572020526646.post-87566480285869250692015-08-23T17:03:00.000+07:002016-01-08T21:39:54.889+07:00Closing Hanoi Hackerspace Site<div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-acDKL6F3O1E/Vdb2aKH04uI/AAAAAAAABBM/zF_qTRfXx9o/s1600/Hanoi-hackerspace-is-closed.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-acDKL6F3O1E/Vdb2aKH04uI/AAAAAAAABBM/zF_qTRfXx9o/s320/Hanoi-hackerspace-is-closed.jpg" /></a><p><a href="http://hanoihackerspace.blogspot.com/">Hanoi Hackerspace</a> site is dead.</p></div><p>After few years of trying to build a hackerspace in Hanoi to promote make culture. We failed to secure <a href="http://hanoihackerspace.blogspot.com/2013/12/hanoi-hackerspace-needs-home.html">a space to host</a> the hackerspace and gather core group of makers. Later Eoin Kinsella and I have moved away out of Hanoi city.</p><p>Now it is up to other projects like <a href="https://www.facebook.com/groups/FabLabHanoi/">FabLab Hanoi</a> and <a href="http://hackanoi.com/">Hackanoi</a> to carry on the torch.</p><br />
