Sansürsüz Internet
Jun 23rd
Türkiye’de 5000′den fazla internet sitesi, ya keyfi nedenlerle, ya ülkemizde bilgi teknolojileri ile ilgili doğru düzgün yasalar olmaması nedeniyle, ya da tamamen bilgi teknolojileri alanındaki cahilliğimiz nedeniyle sansürlenmiş durumda. Bu durum, bu ülkeye hiçbir yarar sağlamadığı gibi, tam tersine, yurt dışında bizi yönetenlerin cahilliğiyle dalga geçilmesine neden oluyor.
Ülkede karar verme noktasında olan bazı kişiler ve danışmanları, teknik olarak ciddi anlamda yetersiz, bu nedenle bir siteye erişimi kapatmak için (ki site kapatma başlı başına saçma bir uygulama) o siteye ulaşılan tüm IP adreslerine erişimi bloklamaya çalışıyorlar. Yetkililer, yetersiz teknik ekiplerinin cehaletinin boyutlarının farkında olmadıkları için, bir IP adresine erişimi blokladıklarında, erişimi engellemeye çalıştıkları site dışında tamamen farklı servislere de erişimin engellendiği farkedildiğinde, bunun çözümünün kendilerinde değil, dolaylı yoldan engelledikleri şirkette olduğunu iddia edebiliyorlar, çünkü danışmanları kendilerine bu açıklamayı yapmaları gerektiğini söylüyor.
Bilmedikleri, algılayamadıkları, algılamak istemedikleri nokta ise, örneğin sadece Youtube sitesinin olduğunu zannettikleri bir IP adresini blokladıkları zaman, sadece Youtube sitesini değil, aynı zamanda Google servislerini, veya Youtube sitesinin ağ altyapısını dağıtmakla sorumlu olan finansal olarak Youtube’dan tamamen bağımsız başka İçerik Dağıtım Ağı şirketlerinin IP adreslerini de engelledikleri. Bunun sonucunda Akamai CDN gibi dünyanın en büyük içerik dağıtım ağlarından birinin bazı IP adreslerine de ulaşamıyoruz. Akamai, dünyada onbinlerce şirkete altyapı sağladığı için, tek bir IP kapatıldığında binlerce şirketin içeriklerine ulaşmakta sıkıntı çekiliyor.
2010 Dünya Kupası’nda vuvuzela sesini filtrelemek
Jun 16th
You can find English filtering instructions on this page.
Dünya Kupası’nda vuvuzela seslerinin başımızı fazla ağrıtması nedeniyle hepimiz bu duruma bir çözüm bulmaya çalışıyoruz. Ben de evde kullandığım Apple Mac bilgisayarı kullanarak, vuvuzelanın ses frekanslarını bulup filtrelemeye çalıştım ve 2 gün önce başarılı bir çözüm buldum. Çözümü İngilizce olarak yazdım ve hemen ilgi çekti, bunun üzerine Türkçe olarak tekrar yazmamın faydalı olacağını düşündüm. Ayrıca TRT’den yetkililer ile görüşerek vuvuzela frekanslarını kendilerine ilettim, çok yoğun vuvuzela gürültüsü olan maçlarda benzer bir filtrelemeyi kendilerinin de yapabileceğini söylediler, umarım faydası dokunur. Fakat bu filtrelemeyi kendiniz yapmak istiyorsanız, aşağıdaki adımları takip edebilirsiniz. Filtreleme için Rogue Amoeba tarafından yazılmış bir yazılım olan Audio Hijack Pro‘yu kullanıyorum.
GÜNCELLEME: Çok daha basit ve neredeyse mükemmel bir çözüme denk geldim. Özellikle vuvuzela sesini filtrelemek için, Prosoniq firması tarafından yapılmış VuvuX adında ücretsiz bir Audio Unit eklentisi. Kullanmak için şu adımları izleyin:
1. Televizyonunuzun line out çıkışını Mac’inizin line in girişine takın.
2. Audio Hijack Pro uygulamasında Default System Input‘u seçin.
3. Input sekmesine tıklayarak Built-in Input: Line In‘in seçili olduğundan emin olun ve Hijack butonuna tıklayın.
4. Sonicworx sitesinden bu dosyayı indirin, zip dosyasını açarak, dmg dosyasını mount edin.
5. Vuvux.component dosyasını ~/Library/Audio/Plug-Ins/Components klasörünüze kopyalayın.
6. Audio Hijack Pro çalışıyor ise, yeniden başlatın.
7. Effects sekmesine tıklayın ve 1 tane VuvuX efekti ekleyin. Bu efekti eklemek için, karelerden birine tıklayarak menüden şu seçimi yapmanız gereklidir: AudioUnit Effect > Prosoniq > VuvuX. Varsayılan ayar bana gayet yeterli göründü, ama ayarı değiştirmek isterseniz Editor butonuna tıklayarak düzenleyici penceresini açarak gerekli değişiklikleri yapabilirsiniz.
How to remove vuvuzela sounds in World Cup 2010
Jun 14th
Türkçe filtreleme açıklamalarını bu sayfada bulabilirsiniz.
FIFA World Cup 2010 would be great, if only those horrible vuvuzelas were not there. If you have a Mac, using the magnificent Audio Hijack Pro application by Rogue Amoeba, you can now filter out the vuvuzela sounds.
UPDATE: I have come across a much simpler and nearly perfect solution. A free Audio Unit plug-in called VuvuX by Prosoniq which is created just to remove vuvuzela sounds. To use it, follow these steps:
1. Connect the line-out of your TV to your Mac’s line in.
2. Select Default System Input in Audio Hijack Pro.
3. Click on Input tab and be sure that Built-in Input: Line In is selected. Now, start hijacking the sound by clicking Hijack.
4. Download this file from Sonicworx site, unzip and mount the dmg file.
5. Copy Vuvux.component file to ~/Library/Audio/Plug-Ins/Components folder of your Mac.
6. If Audio Hijack Pro is running, restart it.
7. Select the Effects tab, and add a VuvuX effect. You can add VuvuX by clicking on one of the squares and selecting AudioUnit Effect > Prosoniq > VuvuX. Default settings were successful enough for me, so I did not change anything after adding the effect. But you can change its settings clicking on Editor button.
Still evolving…
May 26th
Two dimensional codes are getting out of control. Facebook started experimenting with QR Codes, other 2D codes are being widely used in the industry, so my little generator evolves again.
This time I added Aztec Code support to the generator. Also, I now have the possibilty to add more than 50 other symbologies thanks to another great open source software called Zint.
So the generator name changes for the last time (I hope 
). Now you can create your two dimensional codes using QR Code and 2D Code Generator!
Have fun!
PHP QR Code Generator evolves!
Mar 12th
PHP QR Code Generator page is the most visited page on my blog. It has evolved from a small page with a few features into a full featured real time generator on which you can choose from a lot of actions for your device and create different image types, even vector images. As far as I know, there are no free generators on the internet that can match its features, and it is also better than most of the paid ones.
It even works on new generation mobile phones like iPhone or Nexus One.
And as of today, it can also create Data Matrix codes, thanks to the folks who have created the wonderful libdmtx library. So, I have made a name change on the page.
It is now called PHP QR Code and Data Matrix Generator. I hope it continues to prove useful to everyone who use it. 
Adding Facebook and LinkedIn icons on Mystique v2.x
Feb 25th
Mystique theme for WordPress has reached version 2.0. Milenko is very active on updating it. With 2.0, you don’t need to edit any theme files manually, and this makes it much easier to add new social networking icons and replace the default Twitter and RSS icons. Here is how to do it:
First, download the image below (all icons were created by Mark Hewitt, I only merged the LinkedIn icon into the default icon set. You can find other icons on his site.), and upload it to your site. It will go to the SITE_ROOT/wp-content/uploads/ directory, if you did not change your upload destination.
OK, now that you have uploaded your image to your site, you will have to edit your site style. You will add the necessary changes to Mystique’s settings, so that they will not be overwritten after a theme update. Go to your admin panel and select Mystique settings under Appearance. In the settings page, select the User CSS tab, and add the following lines there:
/* Extra navigation icons */ #header a.nav-extra.rss{background:url("/wp-content/uploads/nav-icons.png") no-repeat scroll right top transparent} #header a.twitter{background:url("/wp-content/uploads/nav-icons.png") no-repeat scroll -128px top transparent} #header a.linkedin{background:url("/wp-content/uploads/nav-icons.png") no-repeat scroll -64px top transparent} #header a.facebook{background:url("/wp-content/uploads/nav-icons.png") no-repeat scroll 0px top transparent}
The numbers after scroll in these lines select which icon to show. 0px is the first icon (i.e. Facebook), -64px is the second one (i.e. LinkedIn) etc. with decreasing 64 pixels.
Google is phasing out IE 6.0 support
Feb 2nd
Google Apps sent a notification to their users today. They say that they are phasing out IE 6.0 support in favor of new web technologies like HTML5. This is a very big and important step in the right direction. Web has been held back for too much time because of IE 6.0. I hope that other big portals follow this decision. The mail from Google:
Dear Google Apps admin,
In order to continue to improve our products and deliver more sophisticated features and performance, we are harnessing some of the latest improvements in web browser technology. This includes faster JavaScript processing and new standards like HTML5. As a result, over the course of 2010, we will be phasing out support for Microsoft Internet Explorer 6.0 as well as other older browsers that are not supported by their own manufacturers.
We plan to begin phasing out support of these older browsers on the Google Docs suite and the Google Sites editor on March 1, 2010. After that point, certain functionality within these applications may have higher latency and may not work correctly in these older browsers. Later in 2010, we will start to phase out support for these browsers for Google Mail and Google Calendar.
Global Game Jam 2010
Jan 31st
I had the pleasure of being in the jury for Global Game Jam 2010 in Turkey. The goal of Global Game Jam is to create a playable game in 48 hours. So, the teams do not sleep and try to create the best game in that very limited time. There were very talented and valuable people in this competition and most of the games they created were very good when you think they only have 2 days.
You can visit Global Game Jam site or GGJ Turkey site for more information.
Adding up on Mark Hewitt’s Mystique Facebook Icon Hack
Jan 22nd
UPDATE: This post is only valid for Mystique versions up to 1.7.2. Newer versions need a different approach which can be found on this post.
Well, Mystique is a beautiful theme, but the original icons for Twitter and RSS Feed you see on the upper right were not very appealing to the eye. And the Facebook and LinkedIn icons? They are not part of the theme.
So, what I have done to add those extra icons is, follow the instructions on Mark Hewitt’s Facebook Icon for Mystique Theme post. But editing the style.css file and uploading the icons over and over is not necessary after each theme update, so here are more update friendly instructions:
First, download the following image (all icons created by Mark, I only merged the LinkedIn icon into the default icon set), and upload it to your site. It will go to the SITE_ROOT/wp-content/uploads/ directory, if you did not change your upload destination.
OK, now that you have uploaded your image to your site, you will have to edit your site style. But instead of editing the style.css file directly, you will add the necessary changes to Mystique’s settings, so that they will not be overwritten after a theme update. Go to your admin panel and select Mystique settings under Appearance. In the settings page, select the User CSS tab, and add the following lines there:
Laser marked toe line for darts
Jan 19th
I play darts as an amateur. I love the game and have a darts board in my house. I have recently replaced the parquet floors with a wall to wall carpet and I did not want to place some lath or masking tape on my new carpet.
So I ended up with a laser marked toe line. I purchased a simple line laser, used it as a plumb bob to determine its own place and installed it over my darts board. While installing I did not have a decent camera, so I ended up photographing the whole installation with my old Nokia E70. After purchasing my Nikon D300, I took another photo, with a little bit more quality, which you can see at the end of the gallery below.
