Windows kurulu makinenizde Türkiye lokal'ine sahipseniz ve kodda yerel saat bilginiz yanlış gözüküyorsa muhtemelen default TimeZone yanlış gelmektedir:

java.util.TimeZone.getDefault() => "America/Caracas"

Bunun sebebi aşağıdaki bug'dan kaynaklanmakta:

Çözen degişiklik ise sadece JDK8'e commit'lenmiş:

Yapmanız gereken tzmappings dosyasını bulup aşağıdaki satırı eklemek:

Turkey Standard Time:926,926::Asia/Istanbul:

You can use netsh commands to change DNS settings on most of the modern Windows OS'es. The commands below changes the DNS servers of "Wireless Connection" adapter to Google's DNS's.

netsh interface ipv4 set dnsservers "Wireless Connection" static 8.8.4.4
netsh interface ipv4 add dnsservers "Wireless Connection" 8.8.8.8

The problem is that you need admistrator privileges in order to execute these commands. It doesn't matter for Windows 7 even if you are a local admin, you need to get escalated privileges.

One solution is to save the above commands in a batch file, say "dns-google.cmd" and run it with right clicking and selecting "Run as administrator".

Another solution is to use elevation power toy. You can download it here. After extracting the archive to a location, say C:\Tools\Elevation, create another batch file with contents similar to this:

C:\Tools\Elevation\elevate.cmd dns-google.bat

It will ask for administrator right if you don't run it with right clicking.

BTW, the command below will change the connection to use DHCP issued DNS servers:

netsh interface ipv4 set dnsservers "Wireless Connection" dhcp

Radyo Odtü'yü Android telefonda dinlemek için XiiaLive uygulamasını indirip:

Şu URL'i bu uygulamaya eklemek gerekiyor:

There are two kinds of programmers: those who know that they can not write multi-threaded code and those who think that they can.

700 megabaytlık bir torrent paketi 1 Mbit'lik bir bağlantı ile 2 saatte indirilebilir. Ve genelde bu paket 100 dakika civarında bir video dosyası içerir. Ancak videoyu açabilmek için paketteki tüm rar dosyalarının inmesini beklemek gerekir. Halbuki inmeye başladıktan 20 dakika sonra kesintisiz bir seyre yetecek kadar veri vardır.

Bu bekleme bazen can sıkıcı olabiliyor değil mi? Benim canımı sıktı, ve bir program yazdım: TorrentStream. Bu program sayesinde torrent indirilirken izlemeye başlayabilirsiniz!

I can assume myself as fairly good Java developer. But Android Development learning curve got a bit ahead of me. This might be because of the not-so-familiar platform design by bright Google Developers or me getting old.

I thought that writing things that I don't understand down would help me identify them more easily. Hopefully I will comprehend them and post an update about it. So here they are:

Because of the recent regulations to ban Youtube in my country, my HTC Desire phone became practically unusable since it couldn't reach Google's services. I have bought a VPN service but there was an inconvenience to use it, there was no shortcut to go to the VPN settings page.

After some wandering around the Android source, I have found the "android.net.vpn" package, which is not published in api docs.

Long story short, you can start VPN Settings activity with following code:

startActivity(new Intent("android.net.vpn.SETTINGS"));

Sun Oracle first forces user to fill a form in order to download JDK5, and then e-mails a public URL:

Below is the screenshot of the Bluetooth features of my 7~ year old previous phone, Sony Ericsson T610.



And below is the HTC Desire's, with Android OS 2.1.



Hope Google will implement, and HTC will upgrade these missing features soon.

Türkiyede operatörlerin SMS fiyatlarının çok yüksek olduğunu düşünüyordum, operatörleri ve SMS servislerini karşılaştırdım, ve haklı çıktım. En avantajlı LowrateVoip gibi duruyor, Türkiye'de özellikle paket olarak almıyorsanız SMS anlamsız pahalı :

Lowratevoip	0.06TL/0.03€	http://www.lowratevoip.com/en/sms-rates.html
Clickatell	0.09TL/0.044€	http://www.clickatell.com/pricing/message_cost.php

Kendime yeni bir HTC Desire satın aldım. Ofisten bir de iPhone 3Gs edinip, yabancı sitelerde bulamayacağınız çok çok önemli bir karşılaştırma yaptık: www.milliyet.com.tr internet sitesini açma!

I use the following expression below to quickly count approximate lines of code in eclipse:

^.+\{|\}|;\s*$

What does it do? It simply counts non-empty lines ending with '{','}' or ';'

 

Türkiye'de işlerin yapılma şekline şaşırmadan gün geçirmek zor. Çok ihtiyacım olmasa da google'da "ssl sertifikası" diye bir arama yaptım ve ilk gelen sonuçlardaki SSL sertifikası satan siteleri basit bir teste soktum: kendi SSL sertifikaları var mı? Sonuç vahim...

Well, I couldn't find this post's title on google, so here it is.

Eclipse WST plugin stores java source which are generated from JSP files at this location under workspace:

.metadata/.plugins/org.eclipse.wst.server.core/tmp0/work/Catalina/localhost/<YOURAPPNAME>/org/apache/jsp

Well, what is this? As you probably know, all JSP files are converted to servlets at runtime. Normally you wouldn't need to look at this generated code, but as a JSP novice (like me) would understand some obscure errors somewhat more easily by looking at these sources.

Below is an image hosted on a private web album on picasaweb. I just wonder for how long this image will be accessible:
