Math something

Few years ago I found an interesting pattern, playing with some programming algorithm. I am not sure if I defined the pattern well in terms of math language, despite I was trying to be as close as possible. The hypothesis is:

A sum of all members of consecutive natural odd numbers set equals to amount of set members squared.

Hence,

Set Amount of set members Sum of set members Formula
1 1 1 1 = 1 ^ 1
1,3 2 4 1 + 3 = 2 ^ 2
1,3,5 3 9 1 + 3 + 5 = 3 ^ 2
1,3,5,7 4 16 1 + 3 + 5 + 7 = 4 ^ 2
1,3,5,7,9 5 25 1 + 3 + 5 + 7 + 9 = 5 ^ 2

Let’s prove the pattern works for any set by mathematical induction.

Proof

For n = 1 is true:

 

Suppose that:

 

We need to show that:

 

Indeed,

What proves the Hypothesis. I am totally sure the thing proven is something simple and very fundamental, but I still hope, I’m the first who discovered it:) I also hope there is practical application for it. Unfortunately, I’m mathematically ignorant and I have no clue on what the above means.

Summary

1. My life fucking changed irreversibly
2. I’ve got my first silver hair on my head at the age of 23
3. Gnome 3 is so bad that KDE 4 seems to be flying with desktop effects enabled after it
4. I’ve started cycling and jogging
5. Time to stop forbidding myself beer, coffee and RSS. I already forgot the reason for the activities to be banned.

Cisco is Good

After I passed my CCNA Security certification I was suppose to receive 2 papers: the CCNA certificate and a CNSS 4011 recognition. I’ve received the latter one only. I waited for months for the first one but I never received it.

Being sure I’ll never receive the expected certificate, I referred to cisco certification support persuading them to resend me the certificate because it was lost under the circumstances I could neither control nor influence. I didn’t have a hope to make them resend the certificate to me, but I decided to insist a bit. After a week of letters exchange they agreed to give me a PDF certificate for free, after 3 weeks of letters exchange they agreed to send me a paper version for free. After another month I finally received the desired package. Imagine, they could just just deny my request blaming me in lie or on behalf of some other reasons, but they didn’t, they believed me and fulfilled my request. Good, eh?

University. Secondary Degree Obtained.

My diploma is blue what means I’ve completed my education without honors and outstanding results. The logo on the diploma in my hands is different from the logo in the picture. My diploma has a double-headed eagle on the front, which is heraldic of Russian Federation. In the picture you can see the heraldic of Soviet Union. The picture shows outdated heraldic to symbolize that our education is outdated.

My secondary degree is “Information Systems Engineer”.

Beautiful data center – source found

Recent wiki leaks scandal unexpectedly revealed me the source of cave data center pictures shown in the previous post about data centers.

It’s Pionen DC. It’s placed in a bomb shelter carved in a real rock mountains. Rumors say it can survive nuclear bomb explosion. It’s awesome. 3D panoramas of the DC can be found here.

Dreaming about space. Again

Nobody ever listens to my forecasts, but space is close. I beleive.

I hate VMware server

What is the location of the directory of C header files that match your running
kernel? [/usr/src/linux/include] /usr/src/kernels/2.6.34.6-47.fc13.x86_64/include

The directory of kernel headers (version @@VMWARE@@ UTS_RELEASE) does not match
your running kernel (version 2.6.34.6-47.fc13.x86_64).  Even if the module were
to compile successfully, it would not load into the running kernel.

What is the location of the directory of C header files that match your running
kernel? [/usr/src/linux/include] ^C
[root@hp ~]# uname -r
2.6.34.6-47.fc13.x86_64

Fedora 13. Is. Out.

Weeeeeeeeeeeeeeeeeeeeeeeeeeee!

Two coolest features I’ve noticed hacking around the beta are easy LVM voluming, out-of-box partitions encryption and… Minimal installation mode! Nothing extra, just kernel, shell and drivers. No overload, no dependency added shit. No words can describe best Linux in the world. Download it!
