So far we have talked about Windows 8… Lets talk about Android-x86. Because its development is non-profit and voluntary , i wont be commenting harshly. First of all i have to share my appreciation for their work on porting android to x86 devices.

Last week i updated to ICS-x86 amd brazos RC1 build. Even though it improved a lot , there are still some issues.
Here is a list of problems i have encountered:

• Screen flickers
• Accelerometer & Auto-rotation doesnt work
• Audio driver crashes and causes a disturbing audible noise , you cant stop by plugging headphone.

Other than these problems android runs pretty smooth with last release. But there is something i should notify you , you cant play any of those 3D fancy graphical games NFS Shift , GTA3 etc. , %99 of 3D games and apps doesnt work on android-x86 due to fact that those apps and games were compiled with ARM binary libraries. And when you discard those from market you are pretty much left with crappy apps , notetaking , todo , soundboard apps etc. pretty much like chrome webstore. So even though you install android-x86 i’m pretty sure you will stick with Windows.

thanks for reading

For this reason , i made a decision that i wont do electronics & physical computing as profession every in my life. So i can still have something techy to do and dont care about profits etc. There was one other reason that led me to this decision. It is that i think i have been too generalist and i should scale down my expertise & interest area and become more specialist so i can be more productive. I turned this reasoning into a key prenciple in life. Now i think twice when i switch from working on one technology to other. For example i have been working on PHP & Javascript for over 2 years now. I developed a very complicated web application implementing many features of both php and javascript. I learnt a lot… there is a lot more to learn but i feel my learning curve has become more steep and i become very productive in web app. development. But now i have a very big interest in android app. development… and i am still considering if i’m breaking the rule i mentioned earlier about being generalist versus specialist. But considering my earlier span of interest , i have improved a lot in this manner. I have narrowed down my professional interests a lot.
And besides all this, there is balancing problem between your work & your education. I’m studying Computer Engineering in University of Sakarya. I had very bad marks last term. The truth is i didnt attend most of the classes regularly, i was really busy with personal & freelance works. I came to realize something that doing programming bussiness wont help you much in CS exams. Because what they teach & ask is not much about what you use in real-life programming. They ask you about bigO notations of sorting algorithms , ricatti equations , karnaugh maps etc. I hate impractical information. So i’m wondering should i slow down working on personal & freelance projects.

My intention in writing this article is not only to express myself but also to get your suggestions.I’m sure there are others who had this hobby to career transition. If you know a book , an article or something that you think might be helpful , please comment.

that’s all for now, thanks for reading…

Before reading rest of the article please check out the GlassLayer Web App. itself

Hi everybody,
Finally , i finished this web application i’ve been working for over a year. So i thought it would be a good idea to share my experiences and announce the application here on my blog. Application name has changed a few times along the way but final name is GlassLayer. I’ve made this web application for Glass Art Projects company located in LA. What they offer is that they give a kit of glasses , you glue those glasses on to a base glass as you like , it’s as simple as that and you get to design your very own plate. This was the traditional procedure but now with this new web application you get to design your own plate faster & cheaper.

How it is faster?

In the traditional design process:
You buy the kit , it is shipped to you
You glue your own design , ship it back to company
Company makes the plate , ships it back to you
It took 3 shipments to get you to design your own plate.
But now with the web application we eliminate 2 shipments , you only design the plate and get it shipped to you.

How it is cheaper?

You know in the traditional design you get to buy a kit , but as you design you realize you dont use all of the pieces and some glass pieces gets broken which causes lots of piece waste. By using web application you only pay for the pieces you used.

Features ( End User )

• Hold down CTRL key to select more than one piece.
• Use Remove , Rotate , Layer buttons to control selected pieces.
• Drag & Drop pieces onto plate from piece inventory.
• Undo and Redo when you need to back in design process.
• Use Plate Material button to change plate base color.
• Change Color Palette to access more colors.
• Switch to Transparent tab to access transparent pieces.
• Make sure to register & login before designing if you are thinking about saving or buying your design.
• Use accordion menu in inventory to access different types of pieces.

Technical Part of the Article for Devs.:

First of all , i have to say that i truly appreciate Dimitry Baranovsky’s RaphaelJS library and thanks a lot to JQuery developers. RaphaelJS is a great library for 2D Canvas operations and it even supports IE7… It handles all the cross-browser compatibility issues in 2D graphics. And one can not ignore the power & acceleration ClassyJS added to development of the application.
This project has been my biggest and most time-consuming project so far. I can not express how much this project added to me in terms of experience.Until the end of 5th month of development i have been developing using functional coding discipline. The more the project grow , the messier code has become. And it became impossible to work on it.So i decided to switch to object oriented approach , i researched some of the OOP approaches in javascript and i found ClassyJS library. ClassyJS library is inspired by the OOP approach of Python programming language and as i had years of experience with python in the past , it seemed best choice for me. It took a month to re-code everything in OOP but after i switched OOP , the development got very fast and a lot less confusing.Now it’s about 3000 lines of javascript code but still looks simple , thanks to OOP & ClassyJS.

Features ( Technical ) :

• Single & Grouped Piece Selection
• Single & Grouped Movement,Rotation,Layering,Removal
• Infinite Undo & Redo
• Replay Design Process
• Save & Load Designs
• Piece Bundles

As i switched to object oriented javascript i learned some new tricks in javascript that i’ve never needed or used before.One of them was closures.I dont think i’m yet an expert on javascript or its closures but i want to share my experiences with it. I perceive closures as parameterized callback functions that you can pass arguments into the function.

So when it becomes useful you ask?
It becomes very useful when you are using Jquery & OOP javascript together. Let me give you an example:

<ul>
<li>Content 1</li>
<li>Content 2</li>
<li>Content 3</li>
</ul>
<script>
obj={
counter:1,
set:function()
{
$('li').each(function(){
$(this).html(this.counter);
});
}
}
</script>

This will not work as expected because second “this” pointer becomes current $(‘li’) element.
So how you gonna handle it?
You can fix it by editing it to:

$(this).html(obj.counter);

But wait that’s against OOP approach to assume object name is always going to be “obj”.I wish it was just that , but it will also make it impossible to declare and use more than one instance of that class in one document which can be solved by using seperate documents and showing them in one page within iframe elements.But dont you think it is quite unprofessional?

So that’s where we use Javascript Closures.By using a closure we can pass object pointer keyword “this” into “each()” function of JQuery.
for working example click : http://jsfiddle.net/C7yen/

<ul>
<li>Content 1</li>
<li>Content 2</li>
<li>Content 3</li>
</ul>
<script>
obj={
counter:1,
set:function()
{
setF=(function(ev){ return function(){ $(this).html(ev.counter); } })(this);
$('li').each(setF);
}
}
</script>

PS:
Some of the JQuery functions such as “.bind()” allows you to pass arguments.In those cases you dont need closures.But those functions are very few , maybe its only “.bind()” function , because it’s only one i know.

<ul>;
<li>Content 1</li>
<li>Content 2</li>
<li>Content 3</li>
</ul>
<script>
obj={
counter:1,
set:function()
{<code></code>
$('li').bind("click",{context:this},function(ev)
{
$(this).html(ev.data.context.counter);
});
}
}
</script>

So… What Social Network 2.0 should be?
This is going to be my humble idea, there might be some errors on technical level that i didnt know about , but i can not know those without sharing right :) So please let me know you reviews after you read.

Two Friends on Two Different Servers:
Database :
friends
FriendName ,ListenKey,  EventTriggerURL , TriggerKey …… columns.
personal
…. …, …, .. EventListenURL
When a friendship request is accepted :
Your server will send your friend’s server a person-specific ListenKey and EventListenURL.
And your server will retrieve EventTriggerURL and TriggerKey from your friend.

EventListenURL : for server to check if

• there is something you are tagged is posted etc.
• PM received.

EventTriggerURL : to trigger

• “You are tagged in my post” alert on your friends server.
• PM sent.

How exactly the Servers going to work?

• There will be registered & certified Social Media Server.
• Each social media server will have its own adware policies to provide free service.
• There will be Social Media Servers with no Adverts. but instead with a monthly cost.
• There will be a specific meta tag stating that it is profile page.
• Server softwares will need to be a little different from the usual HTTP servers we use.Server software will check user input to make sure there is no malicious code etc. before triggering other servers.

We are going to search friends on Google:
Each person will set
I would like to be found by:
My Name
Where i live
My Age
etc.
Afterwards these infos. you choosed to be found will be public and will be indexed by Search Engines like Google.Who knows maybe Google would develop a new search tab called “People” :D
So most of the interconnected communication will be based on triggers except chatting.I think to make it work faster chat communication must be based on TCP connection between servers.

Regards
Ahmet
This idea is mostly theoretic and not fully thought and i might add or edit as i notice mistakes or musts in an interconnected social network system.

By the way :
I first thought of this a month ago and later on i discovered some people already working on this.But i wanted to share my thoughts anyway.

I was at Google Chrome DevFest today, it was great in a lot of way , it has been very educating and entertaining in the same time. We’ve been introduced to some of the amazing – yet beta – features of chrome browser. I’ve got to admit that if this features goes mainstream and gets support by more browsers , It is going to change the way we think of the web. The Web might become a whole lot better intuitive & fun experience with this upcoming features. Not only it will change the user experience , but also it will create new possibilities for developers. As an enthusiast Web App. developer , all i can say is that we have to spread the modern browser usage , we’ve got to get more users to upgrade their browsers to one of the modern browsers.It will not only ease the development process but also it will enrich the materials we use to develop web apps and im sure that this will accelerate the innovation in web.

So.. I guess that was enough with the Future Aspect of the Features we’re going to talk about.Lets get into some detail :)

Speech Synthesis And Recognition Made Simple with x-webkit-speech and ChromeVox:

Even though, the ChromeVox was introduced as an accessibility solution for disabled users , I think it has lots of prospect for users with no disability.For instance you can be browsing in another tab , and the tab in the background can alert by telling exact situation that is going on on that tab in background.

What about speech recognition? Well… let me explain , with the speech recognition you can basically command the website handsfree.Speech Recognition has been a big difficulty to implement in old days even in desktop apps.But with the upcoming feature that is introduced with the Google Chrome it will only require you to write exactly nothing more than 2 words and a letter :D “x-webkit-speech”.

<input type=”text” x-webkit-speech=”x-webkit-speech” /> Just like that the text input turns into a speech recognition enable input :).

Web will no longer will be dependant to Web :D

Yea.. I’m aware that’s quite an odd sentence but let me rephrase it.Actually the term is “Offline Web App.”.

This is a great innovation which might eventually take web application development to a next level where it takes the place of desktop softwares and this will accelerate the loading of web apps.Let me explain how… You know in a web app. we have elements that we re-load each time we browse the app. unless it is cached by our browser and stood still the next time we visit.But on an “Offline enabled” Web App. once you visited the App. your browser will store the app. in your local memory and allow you to use and browse the app offline.So as we have stored most of the basic elements of the web app in our local storage , next time we visit that web app. a javascript code can check whether the stored elements are up-to-date or not and if they are up-to-date you might not even need to reload those files which will accelerate page-loading.

All the Max/Msp and PureData Fellows : Get Ready for the Online Audio Creation & Visualization

Creating fancy animations and visualizations online with canvas is no news to us but the new thing is now you can synthesize audio directly on the web with javascript just like you do in PureData and Max/Msp.Think of the possibilities.When audio and graphics is combined the only limit is your imagination :P

Microphone & Camera support comes to Javascript

When i first that microphone & camera support came to Javascript.First, what came up in my mind was the possibility that you can use microphone input and combine it with the audio synth. feature that i mentioned above and you can build a voice changer application – something like vocoder in FL Studio or the T-Pain Vocoder app. in Iphone  -.

And with the camera support you can build and app that tracks hand gestures and scrolls up & down the page accordingly.

That’s all for now

Thanks a lot to Sam Dutton & Paul Kinlan for great presentations.

Thanks a lot to Google Turkiye Team.

Thanks for the gifts Google.

Last week , my delivery – the arduino ethernet shield – from Farnell has arrived. I was totally excited about it but i didnt have much time to play with it last week because i had visa exams.Finally , yesterday i had some time to play with it. I tested some of the example source codes on it and i have to admit that it was dead easy to set up & get to running.There is a plethora of source codes available for the shield , not just source codes but also lots of demonstration videos of what others made with it.This – The Sharing – is one of the reasons i love Arduino Community. A community of makers and enthusiast those help each other . It is a community where imaginations come alive and get in touch with the physical world in a collaboration and im grateful to be part of it :P

Why I am talking about the community , sharing etc. ?
It’s simple.For An Hobbyist , an electronic circuit is not just some specs but also how much of information , tutorial and examples available…

Anyway…I guess this was enough with the Information Availability for this post , we may talk this in another post ;)

• Requires and Arduino board (not included)
• Operating voltage 5V (supplied from the Arduino Board)
• Ethernet Controller: W5100 with internal 16K buffer
• Connection speed: 10/100Mb
• Connection with Arduino on SPI port

visit ArduinoEthernetShield page for detailed specs.

I had some ideas earlier to solve a problem by using an ethernet shield with arduino.The problem is this: You know most of the times, when we are downloading big files we leave computer on , just to have it continuing downloading.But dont you think it’s a bit power consuming? Leaving a high power consuming device ON , a laptop or desktop especially desktop , just to download a file?? Wouldnt it be easier if we had somewhat less power consuming and small devices to download files.So i thought maybe i can do that with an arduino and an ethernet shield.So i googled a bit and i found out some others thought this too.But answers shows that implementing a file system into arduino is pretty hard not the mention the writing speed.But i havent given up this idea yet, i will research more and share whatever i found with you here ;)

Here are some photos from the Ethernet Shield

It has a Cute Little Box :D

Cute isn’t it?

Well.. Thank you for creating such an amazing platform :P

There it is :O :P

mounted on top of arduino and connected to ethernet jack.
in about 10 minutes connected , coded and uploaded :)

I recommend choosing Farnell for flawless payment & shipment process.

Hi my fellow readers ,

In this post , i wanted to share the story behind the bluetooth watch project and answer some questions like why , how and when…

Why?

There is not only one answer to this question , i had a bunch of reasons to make the bluetooth watch…

Remote Mediaplayer Controller

• Navigate through playlist remotely
• See the exact name & info about the playing song.
• Twit what is playing

Social Media Monitoring

• Check out SMS Inbox,MailBox,RSS Feeds,Twitter Updates,Facebook Notifications etc.
• Check in at Foursquare.
• Get information about environment… Closest Cinema , Theater , Restaurant etc…

These were the reasons as a “User”.

Now lets see what reasons i had as a “Developer”
Find the answer for the question : “Can i make it?”
To Push the Limits of my own
To Have Fun

When?

This idea has been in my mind for more than a year.Since i switched to N900 last summer, the need for such a device has increased.Why it increased , because i had lots of buttons to interact with my n95.And they were all remap-able. They are remap-able on n900 too.But it doesnt that many buttons to be useful.

How?

First i needed to choose the microcontroller for the project, at first i thought that i can build such a thing with an ATtiny85 :D fortunately i couldnt find it any electronics shop close to my neighbourhood.Later i decided to go with the Arduino Pro Mini , i had some hesitations because , because i never had programmed an arduino without an USB jack but later i figured it out and used my Arduino Severino as a Programmer.Then i had hesitation about whether to go with a 3310 screen(Graphic LCD) which is easier to solder & drive or go ahead and choose the harder & risky one which is the 6610 screen(Color LCD).Well… i choosed the harder & risky one… because i knew it would be useless and  look really bad with a green graphic lcd…But 6610 screen took a week to solder and drive correctly.There was a tiny tiny socket i couldnt solder so i brought it to a electronic technician(who is an expert on his job) to see if they can get those connection pins out of socket , so i can work easily.You should have seen the face of technician :D . “OMG man hey this is not something a human can solder this needs microelectronic stuff” whatever… I was almost giving up… I abandoned the project for 2 days i guess… Then motivated myself and started again…I learned how to make PCB , tried to make it 6-7 times and couldnt succeed… meanwhile i decided to untape the tape i noticed earlier behind the screen.That was the greatest moment in whole of the project :D i cant explain how much happy i was and both shocked :D All the tiny pins in the socket , had big printed areas to solder :D just check out the images below :D

After solving this problem , my movitation doubled… i soldered screen onto watch , even though i had some problems later too , that didnt lower my motivation after Socket Pins Shock :D Then added 5 navigation buttons 4 for up,down,left,right and 1 for select , and then added tilt sensor…So everything related to hardware was done..Then i started working on software i did some demos. Controlled Media Player of my phone… Then i started re-coding everything in OOP.Created Screen,UI,Widget,Input etc. classes…

Lets see how much it cost to build?

Merhaba Değerli Takipçilerim , Okuyucularım
Bu yazımda sizlerle açık kaynaklı saat projemin arkasındaki hikayeyi paylaşıp , neden , nasıl , ne zaman gibi bir kaç soruya cevap vereceğim..

Neden?

Bu sorunun tek bir cevabı yok , o yüzden hepsini alt alta listeleyeceğim.

Telefon MediPlayer Kumandası

• Müzik listesinde gezmek
• O an çalan şarkının tam adını ve detaylı bilgisini görebilmek
• O an çalan şarkıyı twitter profilinde paylaşmak
  ve bunların hiç birini telefona dokunmadan saat üzerinden yapabilmek :)

Sosyal Medya Takibi

• SMS Gelenkutusunu , Yeni Gelen Mailleri ,RSS Kaynaklarını,Twitter Güncellemelerini ,Facebook Uyarılarını saat üzerinden kontrol ve takip etmek
• Foursquare’da yer bildirmek.
• O an bulunduğunuz çevre hakkında bilgi alıp , en yakındaki Sinema,Tiyatro,Restoran bilgisini direk saat üzerinden görebilmek

Bunlar “Kullanıcı” bakış açısıyla sahip olduğum nedenlerdi.

Şimdi de bir “Programcı” bakış açısıyla sahip olduğum nedenlere bakalım.
“Yapabilirmiyim” sorusuna cevap bulmak
Limitleri zorlamak
Eğlenmek

Ne Zaman?

Bu fikir bir yıldan fazla süredir aklımdaydı.Geçen yazın başında N900 kullanmaya başladığımdan beri böyle bir saate olan ihtiyacım arttı.Neden Arttı? Çünkü önceki telefonum olan n95 üzerinde telefonla etkileşime geçmemi sağlayan bir çok buton vardı ve bu butonların hepsinin işlevi ayarlanabiliyordu.N900 üzerinde butonların işlevi değiştirilebiliyor fakat butonların az olması bunuda bir çözüm olmaktan çıkarıyor.

How?

En başta proje için bir mikroişlemci seçmem gerekti, başlangıçta ATtiny85 mikroişlemcinin işimi görebileceğini sandım :D Neyseki yakın çevremdeki elektronikçilerde bu mikroişlemciden bulamadım.Sonrasında Arduino Mini Pro kullanmaya karar verdim, bu aşamada da bazı endişelerim oldu , çünkü daha önce hiç TX&RX üzerinden programlanan bir geliştirme kartı ile çalışmamıştım, ama sonrasında Arduino Severino’mu programlama arayüzü olarak kullanabileceğimi öğrendim ve bu problemde çözülmüş oldu .Bunuda çözdükten sonra saatim için bir ekran seçmem gerekliydi 2 seçeneğim vardı Ya bir çok yönden kullanımı kolay ama renksiz 3310 ekranını seçecektim yada kullanımı zor ve riskli renkli 6610 ekranını seçecektim.Zor ve riskli olmasına karşın 6610 ekranını seçtim .Çünkü renksiz bir ekranla saatin kötü gözükeceğini ve büyük oranda işe yaramaz olacağını düşündüm.Ama bu seçim ekranı çalışır hale getirmemin bir haftadan uzun bir sürmesine sebep oldu.6610 ekranının çok çok küçük pinleri olan bir soketi vardı , lehimlenmeyecek kadar küçüktüler bu yüzden yakınlardaki uzman bir elektronik teknisyenine götürdüm ve bu pinleri kullanabileceğim bir şekilde dışarı çıkarıp çıkaramayacaklarını sordum  , .Adamın o anki yüzünü görmeliydiniz :D .” Yok arkadaşım bunu nasıl lehimleyelim biz küçücük bişey bu mikrolektronik lazım buna “herneyse … Bunu duyduktan sonra neredeyse pes ediyordum… Projeyi 2 günlüğüne tamamen bıraktım…Ama sonrasında bir şekilde motivasyonum geri geldi…Baskı devre nasıl yapılır öğrendim, 6-7 defa sokete uygun devreyi yapmayı denedim … bu sırada daha önceden ekranın arkasında farkettiğim bandı kaldırmaya karar verdim.Projedeki en şok edici anı o zaman yaşadım :D O an ne kadar mutlu olduğumu anlatamam :D O soketin içindeki küçücük pinlerin hepsi bandın altında açık ve geniş bir şekilde kullanım için çıkarılmıştı :D alttaki resme bakın ne demek istediğimi anlayacaksınız :D

Bu problemde çözülünce motivasyonum ikiye katlandı… ekranı saate lehimledim , bundan sonrada problemler yaşamış olmama rağmen hiç biri Soket Pinleri Süprizinden sonra motivasyonumu düşüremedi :D Sonrasında 4′ü yön ve biri seçim için olan 5 button , ve eğim sensörü ekledim..Bu aşamada donanıma dair herşey bitmişti..Yazılım tarafına çalışmaya başladım bir kaç test yaptım,Basit bir arayüzle telefonumun media oynatıcısını kontrol ettim… Sonrasında tüm kodları Nesne Yönelimli olarak tekrar yazmaya başladım Ekran , Widget , Girdi  sınıfları oluşturdum…

Peki bütün bunları yapması ne kadara maloldu?

Total : 200 TL ~

First One is : NPlayer
I’m telling you if you are still using an n900 and havent checked out this app. you are missing a lot.This app. called NPlayer is a youtube client.What makes this application special is its slick and kinetic UI that works greate both in Landscape & Portrait modes.Actually it’s UI Layout is very similar to Youtube UI on Ipad 2.
Basically supports everything you can do on youtube on a desktop browser.

Second One is : Sociality
Sociality is Facebook client application for Maemo5 with user friendly user interface.
Works both in the Landscape & Portrait Modes.
Kinetic Scrolling UI
Supports Facebook Chat
Run in background & Auto-Update Mode.
Notifications by Vibration
Nice Home Menu

Hardware Updates :
5 pushbuttons added for navigation.
Tilt-Sensor added.

Software Updates:
I designed watch UI on top of Vertical Screens called Widgets.In these Widgets, we’ve got buttons , labels etc.

There still some lacks & issues to solved.As soon as i have some free time i will work on those and release source code with Android & Maemo Apps. to talk to watch.If there is anything about the code that is bothering you please dont hesitate to comment or contact me :) .Suggestions are welcome.

Here is a scheme of the Class Structure:
