R.E.M. İstanbul’da!

19 July 2008 | Kategori: Musics | Yorum (1)

Bu nasıl bir yaz, nasıl bir konserler zinciridir, nasıl yıldızlar geçididir anlamak mümkün değil.
Kylie Minogue, Travis, Metallica, Björk ve Coldplay’den sonra Kanat Atkaya’nın iddiaları gerçek oldu. R.E.M. İstanbul’a geliyor.
Buna kalp mi dayanır, sayın dinleyiciler…

CentOS’da NTP kurulumu

16 July 2008 | Kategori: Documents, GNU/Linux | Yorum (0)

CentOS Linux sunucunuzun saat sürekli olarak bir ileri, iki geri şeklinde gidiyor, müşterilerden sürekli “sunucunun saati yanlış” diye geri dönüşler geliyor ve siz hala “date” ile uğraşıyorsanız, boşuna uğraşıyorsunuz.
Kurun sunucunuza bir NTP servisi, saat/tarih işleriyle o ilgilensin.

“NTP nedir” derseniz, hemen sözlük’ten bir alıntı yapayım; network time protocol un kisaltilmisi. bilgisayarlar arasinda network yada internet uzerinden zamanlarin senkronizasyonunu saglar. linuxta rdate komutu ile bir tane timeserver adresi girerseniz bilgisayariniz o serverin saati ile senkronize olur.

Öncelikle kurulu değilse, YUM paket yöneticisi ile ntp paketinin kurulumu yapalım.
# yum install ntp

Kurulum sonrasında servisi başlatalım.
# chkconfig ntpd on

Sunucu saatinizi public bir NTP sunucusu olan time.windows.com’dan senkronize edelim.
# ntpdate time.windows.com

NTP’yi başlatalım…
# /etc/init.d/ntpd start

Jenerik domain demek iyi proje demek midir?

14 July 2008 | Kategori: Informatics, Web | Yorum (0)

Turkticaret.net‘in web.tv domainini alması webrazzi’de epey bir yankı uyandırdı. Ancak gözden kaçan bir durum var ki; jenerik domain =/ iyi proje. Bu durum özellikle de turkticaret.net için geçerli bir formül.

Bugün, başta web 2.0 projeleri olmak üzere Nokta A.Ş. elinde binlerce domain bulunduruyor, bir çoğunu da teker teker yayına sokuyor; blogcu.com, sinemalar.com, izlesene.com en çok ziyaret edilen Nokta‘ya ait projeler…
“Domain iyi, projede iş yapar” mantığıyla bakarsak; dünya üzerinde milyon dolarlık domainler (movie.com, search.com, mail.com) yeteri kadar başarılı olamıyor?

Webrazzi’deki son haberde Turkticaret’in web.tv domainini almasındaki nedenin “Popstar gibi programları internet üzerinden gerçekleştirecek olan web tabanlı son derece büyük bir yatırımın sadece alan adı tarafı” olarak belirtiliyor. Ancak TurkTicaret’in çalışma mantığını bilen, şahsen olmasa da Murat Yanıklar’ı bilenler web.tv projesinin bir Popstar projesinden öteye gidemeyeceğini, domainin kendisi gibi global arenada boy göstermeyeceğini bilirler.

Onlarca sunucuya tek pencereden erişimin yolu; mRemote

09 July 2008 | Kategori: Documents | Yorum (0)

mRemote, Windows üzerinde çalışan
VB.NET ile yazılmış MSSQL desteği bulunan, tab (sekme) desteği ile aynı anda birden fazla sunucuya bağlananlar için enfes bir özgür yazılım.

mRemote sayesinde birden fazla mstsc komutu girip, onlarca PuTTY penceresi açmak yerine tek pencereden işlerinizi halledebiliyorsunuz.

Kapak olsun?
