Launch A Web Application in Compact Mode using Chrome

I have been looking for a kind of launcher for web application, for example email, CRM app, WordPress Admin page, etc. that works like desktop client application. So I can have more space and focus on the application I am working with.

Sometime a go, Chrome had an experiment feature that enable you to hide tabs, address bar. But the feature somehow no longer there. I just found that Google has creatively create a (new to me) feature that help you do this.

To do this is very simple. For example I would like to create a shortcut for WordPress Admin page, or for any webapp that you’d like to have.
1. Open Google Chrome.
2. Open your WordPress Admin page, example: https://yourblog.wordpress.com/wp-admin/
3. Click the Menu icon on the right-top corner, then select More Tools, click Add To Taskbar..
4. Rename the title as you like. Check the Window chexbox. This will hide tabs and addressbar when you open the shortcut. Then click the Add button.

That’s it. Now you have your application shortcut in your taskbar. To delete it just right click and unpin it.

Simple way to execute a command on startup in Ubuntu

I would like to share with you a simple way to execute commands on startup in Ubuntu. This tip is very useful for example I have an issue on the Netatalk service that do not run properly so every time I have to run the command to restart the service after I login to Ubuntu.

All commands that you need to be executed must be stored in etc/rc.local setting. Open terminal then execute this command:

sudo nano /etc/rc.local

Add the following command to restart Netatalk service, right before “exit 0":

sudo service netatalk restart
exit 0

That’s it! It’s so simple. I have solved the Netatalk service problem for now. So I have more time to take a look what is the problem with the Netatalk service.

The New Arduino Esplora

The New Arduino Esplora

Arduino Esplora is a new Arduino board just launched today. It has game joystick shape.

The Esplora uses an Atmega32U4 AVR microcontroller with 16 MHz crystal oscillator and a micro USB connection capable of acting as a USB client device, like a mouse or a keyboard. Esplora also has lots of input/ouput:

– Analog joystick with central push-button two axis (X and Y) and a center pushbutton.
– 4 push-buttons laid out in a diamond pattern.
– Linear potentiometer slider near the bottom of the board.
– Microphone for getting the loudness (amplitude) of the surrounding environment.
– Light sensor for getting the brightness.
– Temperature sensor reads the ambient temperature
– Three-axis accelerometer measures the board’s relation to gravity on three axes (X, Y, and Z)
– Buzzer can produce square-waves.
– RGB led bright LED with Red Green and Blue elements for color mixing.
– 2 TinkerKit Inputs to connect the TinkerKit sensor modules with the 3-pin connectors.
– 2 TinkerKit Outputs to connect the TinkerKit actuator modules with the 3-pin connectors.
– TFT display connector connector for an optional color LCD screen, SD card, or other devices that use the SPI protocol.

With a lot of features so you can do almost everything using Esplora.

Painful Upgrade to Mountain Lion

I have been waiting for Mountain Lion since its preview release. It always make me feel impatient for something new from Apple. Then the new OSX was released few weeks ago. I immediately opened the App Store to download the installation.

It was a very surprise that the download only took few minutes, the message says the download is finished.  Something is wrong. I opened the installation, and it says “this copy of the install OS X Mountain Lion application can’t be verified. it may have been corruped or tampered with during downloading”. What is that? I checked to Application in Finder. The file size is only 74MB.

My next default procedure when find something like this is checking the error to Google. Many people have same problem. Then I went to Apple communities support page. There are few similar problem with various solutions. So I tried every single possible solutions, one by one. No luck. It always stops at 50 or 74 MB then end up with the same message.

This problem already taken my two sleepless weekends. I redo everything again, did each step carefully, and end up with the same error. I can’t believe this problem happen in Apple product. I gave up. That’s it.

I am happy with OSX Lion. I think I need no new features that mostly are for social media apps. I don’t do it on my Mac. I will try again after the next minor release, 10.8.1, may be.

So I sent an email to Apple Support, tell everything what I have done, and asking for refund. The support lady replied on the next day, ask me to go to support page, exactly the same procedure that I have done.

Ok. Why not give one more try? I checked again what other people have done, check the log file in Console, examine the network, tried to download other apps. I have no problem with my Mac, I have more than enough free space, no issue on the network, and the internet connection is also good.

Until I realized that I missed one solution in communities support that suggested to use Hotspot shield. I simply ignored the solution. It just doesn’t make sense that this can solve the problem. Hotspot shield is for security connection. I have upgrade many other OSes, Linux, Windows, and of course upgraded OSX many times without having Hotspot shield and never had any issues.

But that is it! After setup the Hotspot shield, I redo everything again. I removed the installation program at Application in Finder. Deleted cache under ~/Library/Cache and temp files in com.apple.store folder. Then I opened the Apple Store again, download the Mountain Lion again.

I checked the progress bar with my fingers cross. I opened the Purchases in App Store, and finally saw the progress bar moving slowly. Then at the first time I saw it passed the 74MB size. Wow, this must be good. I leave it open and went to bed. In the morning it passed 1GB! So I went to work and leave my Mac finish the download. Yes, I found it was completed when I was home in the evening. Then the rest step is very easy and run very smooth.

I haven’t tried anything yet but writing to this blog. I already seen on the dock that there is a sign on the icon that My Virtual Box doesn’t work. Pfviewh! At least I have finished the upgrade. I will find out solution for the next problem later.

So this painful upgrade takes two full days to download the installation package. It also took my three weekends to redo every steps with failures and to find a right solution for the problem I had. What a frustrating upgrade I have ever done from Apple. And I still can’t believe that Hotspot shield solve the problem, and I still don’t know what causing the problem.

Macbuntu Precise Pangolin Wallpaper

I just completed the upgrade to Ubuntu 12.04 Precise Pangolin. I get to like the new look of Unity and the HUD simplicity design.

Macbuntu Precise Pangolin on Wood 1280×1024

 

So I created a new natural, simple and clean wallpaper, to make it look nicer. I took the idea of this nice text design from Oneiric Ocelot wallpaper by Tux-planet. The text is blended to the wood skin from maciad.com, and give a burned-pressed effect on the wood.

The logo is from the two OS that I use, my favorite systems, Mac and Ubuntu, that work together for my daily work.

Yes, it says Macbuntu, actually it is my work-in-progress to find the best Macbuntu theme for Pangolin. Tell me if you like it.

Upgrade Netatalk

At last I have a chance to upgrade new updates of Netatalk 2.2.2 that already released two months ago.  The Time Machine and my shared folders work great with no issues. I use Ubuntu 11.04 and my Mac use latest version OSX Lion 10.7.3.

I see that new features are not really for Ubuntu, but there are some updates and bugs fixes that are useful to users. So it is recommended to upgrade for users who uses version 2.2.1.

This article is for you who already used Netatalk 2.2.1 and follow this post. If you are new to Netatalk, please follow the steps in that article. Read more of this post
