In the planetarium

it’s the week end…

i have to do something instead of staring at my laptop’s screen and declaring some integers, or surfing my google reader

so, i’ve read about an event in BibAlex related to a mini book fair, i’m not fan of such things but lets try, may be i can find a book related to programming

but it was a smaller event than what i was expecting, and i found some shelves having books about VB, C# and Windows Me

anyway, i got out of the hall looking for something to do, and there was the planetarium…

for those who don’t know it, it’s the blue-stripped moon seated beside the sun of BibAlex

With Ubuntu [A Fresh Install]

No, the old install didn’t crash !!!

i just was very anxious about the new Ubuntu release (Karmic Koala), so i installed the RC version

and as u know i hate to install a fresh install of any OS until the currently running one crashes, hangs and cries to let it die

But u r killing me !!

ok, i admit that it was an  innovative method that depends heavily on XML Programming,

i can say it saves a lot of time during developing the whole system, as the time required for every feature is nearly constant

just some generic methods to solve all the problems that can be found

but as known “Generic” can not cope with “Performance”, as there must be unneeded steps done with the small/mid sized problems, and it will be fully utilized with the problems that satisfies the general case problem -which is most of the time rare-

and even if u had the general case as the smallest/simplest case, u’ll waste some performance trying to combine those tiny generic solutions to solve the larger problems

Quotes i won’t forget

here are some phrases i’ve heard from some people i’ve met, mainly in FCIS -my faculty-

“this is the learning curve in FCIS”

Mohamad Meshref…. (SDE Microsoft Redmond)

*that graph was somehow accurate -for me anyway-

SQL Multiplication

i was shocked to find that there is no aggregate multiplication functions in SQL, something like

select mul(number) from table

but i needed to use a multiplication function…, so as usual i googled it and found this statement

select exp(sum(log(cast(number as float)))) from table

that does the multiplication,

so with a mouth half opened i tested this line and it worked
