Case 2: Down- Thomson Paradox
Don't UPGRADE UR BANDWIDTH lol
6 people lived in an apartment, and they subscribed internet and shared among 6 of them. 4 of them are heavy streamers that like to stream video, one of them is a freaky gamer and another one was a blogbloglophilie.
The freaky gamer noticed almost everytime, his gaming experience wasn't a good one, and he realized that it was those streamer's fault that selfishly stream video without caring on other's need on internet usage. The gamer shouts at those streamers occasionally to alleviate his situation,and those streamers felt guilt at times, and stop their streaming...
Finally, the blogbloglophilie, the gamer, and the 4 streamers are extremely unsatisfied with current bandwidth, and after thorough discussion...they decide to upgrade their bandwidth...
And after upgrading his bandwidth, his gaming experience was truly great. However, he soon noticed the speed of gaming decreases, and the bandwidth sucks to the point that blogbloglophilie cannot blog well. And both the gamers and blogphilie felt weird. They phoned their ISP and the ISP confirmed that their bandwidth is upgraded.....
But, the bandwidth speed somehow worst than before @.@.....both of them noticed.......and the 4 streamers also noticed that their streaming performance is better before they upgrade their bandwidth......
Why so?
Hint#: The ISP do upgrade their bandwidth, and the clue is lied somewhere...lol

Bandwidth war part 1
This is a post made after reading some wikipedia post, and also hearing some complaint from my friend about internet speed. He complains about internet speed being sluggish because his friend is downloading, therefore, making his internet browsing suffers...And I made a few variation to makes thing more interesting.
Case 1 - Prisoner dilemma
Cases: Suppose, there are two students staying in a room, the room was equipped with a wifi, and both of them pay equal amount of money to use the internet. However, both students did not know each other and thus they rarely talk much about problem.
And thus, one of the students is know as Mr. H. He wanted to download anime and games. However, he wanted to browse internet as well because he need to browse internet to do his homework.
-------------------------------------------------------------------------------------------------------------
He realizes this phenomena occur
1. If he downloads anime and his roommate doesn't, his download speed will plum high (skyrocket 1MB per second!) and while downloading, he can browse internet smoothly as well
2. If he did not download anime, but his roommate does, he will be unable to surf internet smoothly (speed of browsing = Cemara browsing speed)
3. If both of them download at the same time, he would be unable to browse the net. However, at least the download is still running at a 10kb speed ( better than none , A say )
4. If both of them did not download, both of them are able to browse the internet.
And recently, Mr.H wanted to watch an anime named "higurashi", which has a space of 1GB. But at the same time, he wanted to browse the net ( to msn with gf, to go facebook and garena etc etc )
And thus he thinks....
" I noticed that my roommate also like to download anime...but I really wanted to download that anime le. If I stop downloading, and if my roommate download, i won;t be able to go facebook. If he downloads and I download , I would also be unable to browse internet, but at least, my anime was downloading at a 20kb speed....better than none. But if my roommate did not download at all, I can browse the net and download freely YEAH!
And so, Mr, H formulate a graph
I download, my fren dun download - 10MB download speed + browse internet
I download, my fren also download - 20kb download speed + no internet browsing
I dun download, my fren download - no download + no browsing.
And H say. looking the situation, download > no download.....
And so, H decides to open xunlei when he browse internet......
-------------------------------------------------------------------------------------------------------------
However, the thing H doesn't realize is, his roommate was thinking the same thing too. And his roommate was thinking the same thing too. So both of them download= result - 20kb download speed + KNS browsing speed....
-------------------------------------------------------------------------------------------------------------
However, if both of them decide not to download, at least both of them are able to browse internet........

Chinese New Year....
***5 years ago****
Early 6 A.M. ......
Snore...Snore...mumbling in dreams...
WAKE UP LO! NEED TO WORK! WORK!!!!!!!
Aiya, 6AM only mah, usually i thought work starts at 7AM.....
CHINESE NEW YEAR AH. We need to wake up earlier la.....
And thus, this is my childhood Chinese New Year memories. Waking up earlier, Working twice harder, and feeling more tired than usual. Perhaps, it was the reason why part of me resist Chinese New Year. And while people view this traditional day as a day they celebrated, letting off the stress in work and mixing around, I believed Chinese New Year is the day when I accumulated stress, mainly because of massive amount of customers, and also complaints from those customers that act like boss
Aiyo, where is my food! 15 minutes already la
Yes Yes, your food will be coming soon...
(deep in heart): niama! You had no idea how busy I am. I had more work to do, thanks to those customers like you.
We grumbled among each other more than usual, ranging from mother scolding me for taking a 1 minute reading news, to me scolding my sister because of messing up customer's list. ( and of course, there are times I shouted at my mother.) There are times I got emo-ed and refused to work, there are times of anger looming up the atmosphere. There are times I just wished chinese New Year vanished into thin air. But despite that....
I worked from day 1 to day 7 along with the rest of family. The anger during work, no matter how loud the cursing is, vanished after the work's done. The happiness looms in our face when we received the pay for our hard work, ( rm10 for 5 hours is enough to satisfy me), and despite the tiredness, I am still able to bounce around, asking angpau from family and friend's parent, ans glued in TV whole night...Until I suffered next day because of insufficient sleep.
And after few days, I would look at the money I obtained,, and I will start thinking of plans...such as saving money to buy PS2, PC, etc etc, even though RM100 is all I got, OOPS, and 75% goes to my account, my mother regulation...And as usual the RM 25 just gone poof-ed few days later, and my dream of a PS2 poof-ed as well.
************************************************************************
The younger me used to feel jealous on my peers that had a normal Chinese new year, they can glued to the TV whole day long, and hanging out with families to some luxurious shopping complex, or even going to vacations, while I was stuck in my mother's shop, serving those happy customers with a bad mood...
But I didn't realize. If I would had undergone the usual routine Chinese New Year. I would had enjoyed the first 1-2 day, and getting bored at the 3rd day as I glued in the TV channel and spamming my mouth with those junk food.Precisely because the holiday ( mother granted ) in Chinese New Year is a rare occasion, I never ceased to make interesting schedule during those days
----> mostly it's about cycling 5-6 km , asking for angpao from friends. While normal friends seems to be confused with my deed, there are true friends that are equally as enthusiastic as me to cycle 5-6 km in search for angpao.
Even though it's an RM8 (for 5-6 km cycling and 5-6 hours), it's always something I would do each year...
**************************************************************************
Now I am in US, and ironically, my dreams of " relaxing " in Chinese New Year became true. But still, I enjoyed those working days and cycling days back in Malaysia. Even though it means less comfort, more hard work, it was nevertheless something I will miss.
My chinese New Year was a CNY lack of Yee-Sang and bakkua, loads of work, but I doubt without those years of hardwork, I might as well ended as a spoil brat without any respect to working attitude. And glad-fully, I am the one that curse the lazy bumps instead of being the lazy bumps itself.
To those customers that I greeted " Gong Xi F*** chai ", may you have a Gong Xi Fa Chai Year.
And happy CNY
