Ethernet issues

Extending the RAM memory from 3 GB(3 slots with 1 GB of RAM slots) to 4GB of RAM, by adding a compatible RAM module to the remaining slot(1GB of DIMM 6400 RAM, at 800 Mhz) turned out to disable the Ethernet card. So I tried resinstalling the ethernet driver, the BIOS and motherboard device drivers to no avail.

Ultimately I installed a new PCI Ethernet card and the networks started working. Thankfully I had an Ethernet card stored in a warehouse, otherwise I would be left spending for a new Ethernet card or not possessing network connection at all.

Gabriel's idiocy.

Despitemy seemingly intact ego, sometimes I LOOK at myself  with self loathe, feeling guilty that such simple operations like radicalization of a fraction would fly over my head. I blame it on sleep deprivation, which is diminishing over time.

Reviewing some trigonometry, I stumbled upon this exercise on the excellent Free and Open Khan academy website.



 

                ___


Of course BC  is equal to 5 since tan is 1 and the other side(opposite to the angle) is 5.

However, it is not clear how

 5
___
√50


  1
____
  ___
√2


But the answer is: radicalization, i.e. multiplying the unit-length denominator by the monomial(term). In other words square root of 50 divided by square root of 50 multiplied by 5 divided by square root of 50.

Here are the steps:

Which radicalized equates to:

First C++ program

I decided to finish a screencast as quick as possible without loosing profession touch It took me 2 days. Way  too much, so I must either decrease the quality to out of the mill screencast, or take pauses from game development every day to work progressively. Seems that C++ is the logical step, since right now I am reviewing many of the concepts I had long time stopped using.
