Hangi platform

admin — Sun, 27 Mar 2011 20:20:33 +0000

Yazilim ile ugrasanlarin muhabbetlerinden eksik olmaz

- java daha iyi, platform bagimsiz. – olur mu C# icinde mono var.

Bir platforma bagli kalma fikri. Yillar icinde onemini pek yitirmedi.

Son kullanici acisindan ise mobil ( gezici ) olmali. Son 3-4 yildan beri mini dizustu ( notebook) lerin, tabletlerin ve gelismis cep telefonlari ile her yerde cevrimiciyiz.

Bilgisayarimin kismen bozulmasi ile webOs heyecani sardi beni. Uzerinde ugrastigim projelerin svn de olmasi projeleri sorunsuz aktarmami sagladi ama calistigim ortami tekrar diger dizustune kurmak bayagi bir zaman alacak.

Bunu “tamami ile platform bagimsiz nasil calisiriz” yazi dizisi haline getirip yayinlamayi dusunuyorum.

Are you aware of this?

The Joel Test

Do you use source control?
Can you make a build in one step?
Do you make daily builds?
Do you have a bug database?
Do you fix bugs before writing new code?
Do you have an up-to-date schedule?
Do you have a spec?
Do programmers have quiet working conditions?
Do you use the best tools money can buy?
Do you have testers?
Do new candidates write code during their interview?
Do you do hallway usability testing?

Naturally, i answered them all yes. what a perfection.

Convert javascript ticks to .net ticks

admin — Tue, 01 Jun 2010 19:43:41 +0000

js.getTime() returns ticks since 1.1.1970 however .net ticks since 1.1.2000.
I had a case where every clicks is recorded on client and processed on the server. Here is how i convert js ticks to c# ticks.

Js Code
tracking.StartTime = new Date().getTime() – new Date().getTimezoneOffset() * 60 * 1000;

C# Code
const long ticks1970 = 621355968000000000;
DateTime startTime = new DateTime((Convert.ToInt64(ta.StartTime) * TimeSpan.TicksPerMillisecond) + ticks1970);

happy coding.

by the way, the code has some errors.

where is SQL Server Management Studio?

admin — Sun, 14 Feb 2010 22:06:43 +0000

i could not install SQL Server Management Studio.

The solution Microsoft offers is here , probably it takes one too many hours

My own solution is

install Visual Studio 2008 Sp 1 , completely uninstall Visual Studio 2008. never ever use/install for home environment again.
install Sql Server 2008 Sp 1, reinstall it using original package.
Install Visual Studio 2010 RC

It would give so many errors during installation, dont count them on, just ignore
