Approx is like the equivalent of Microsoft’s WSUS or SUS on a Debian system. It’s a proxy service that runs on a server to save on bandwidth and time for installing programs and updates by utilizing a cache. Instead of continuously downloading, the updates are stored locally on the Approx server. This helps if you have multiple Debian systems that will need updating. An added bonus is that it works on Ubuntu also (seeing as Ubuntu is a Debian derivative).

To install:
apt-get install approx

Here are the lines that I have added to the file /etc/apt/sources.list on the client computer:

deb http://server:9999/debian/ stable main non-free contrib
deb-src http://server:9999/debian/ lenny main non-free contrib

deb http://server:9999/security stable/updates main non-free contrib
deb-src http://server:9999/security lenny/updates main non-free contrib

deb http://server:9999/volatile lenny/volatile main non-free contrib
deb-src http://server:9999/volatile lenny/volatile main non-free contrib

I have two weeks left of summer to complete a piece of coursework. But this is no ordinary piece of coursework, you see the topic in question is “Work Experience” – whats wrong with that you may be saying to yourself. Well you see kind people, the tiny tiny tiny tiny tiny tiny problem of writing a approx. 250 word piece of literature on Work Experience is the fact that me nor my classmates have never done any work experience whatsover. The only saving grace is that it will allow me to be creative, one thing in life i crave day in day out.

So this begs the question, what fantastically, imaginative part-time job could i think of. What incredible task could i for a week endeavour. How could the school claim it to be a mis-truth that i trimmed the Queens Corgi’s for five day’s or that i spent a week organizing Richard Branson’s letters of complaint.

At the end of the day however my text book seems to cover being a office clerk in HSBC the best.

anything to get better that a B for my last piece (Bearing in mind my sister is A*)

Alaattin’in 250 adet audio CD’si var. Teknolojinin gelişmesi ile kendine bir bilgisayar edinen Alaattin elindeki bu CD’leri MP3 formatına çevirerek arşivini DVD’lere kaydetmek istiyor. Bu sırada da kaliteden az fire vermek için MP3 bitrate’ini 256KBPS olarak seçmek istiyor. Alaattin bu işlem için bakkaldan kaç tane boş DVD almalıdır. (DVD’lere en fazla 4.5 GB veri depolanabiliyor)

Çözüm

Çözümü görmek için aşağıdaki görüntüsüne tıklayınız.

Dönüşüm terimleri:

1. Toplam audio CD’ adedinin saniye cinsinden değeri
2. Bu süredeki ses bilgisinin 256KBPS’deki Kilobyte cinsinden boyutu
3. Kilobyte’ın GB cinsinden değeri
4. Bu GB’ı alabilecek DVD adedi.

Yani Alaattin’in bu işlemi yapabilmek için 9 adet DVD’ye ihtiyacı var.
