MyT LaFibre (10Mbps limited at 50GB monthly)

Terms:-
B : byte = 8bits
Mb: megabit = 1024 * 1024 bits

MB: megabyte = 1024 * 1024 bytes = 1024 * 1024 * 8 bits

GB: gigabyte = 1024 MB

Been more than a month now since been using Orange’s (Mauritius Telecom) fibre connection with 10Mbps speed i.e. you downloaded at 1MBps. Since I usually use peer to peer download method (Torrents), I can say if there are enough peers, most of your downloads will be at that speed. If you use file sharing websites, then a speed limitation might come from them 😉

10Mbps is more than enough for me. My HD video contents download faster than I can watch. A 700 MB Ubuntu ISO takes 10 minutes to download. A 1400 MB 1080p .mkv video takes about 20 minutes to be downloaded. I can download sequentially to watch as it downloads. Why should I want a 100Mbps connection right now?

The Catch?

The 10Mbps is only applicable to the first 50GB traffic. Yes. Both downloads and upload in that. Think at the beginning of the month, I saw about 54GB in the customer section on Orange’s website. But that’s it. Being a responsible torrent user is harder. I usually seed to 1.10 ratio. I have to wait when the 50GB is over to seed unlimited till the end of month.

50GB is used up in 15 days.

My mom and sister are heavy “youtubers”. I had to tell my mom yesterday to limit watching her serials to extend the high speed time. 50GB is really not enough for a regular family usage.

No 2Mb/s for local and youtube when package is over

When your 50GB ends, you go down to 1Mbps. Seriously? Make it to 4Mbps atleast!

WiFi weaker

I noticed the WiFi signal is a bit weaker than the previous ADSL modem. Anyone else noticed this?

Online Gaming
I usually play League of Legends online. Found my ping to be almost same. Nothing to note here.

Conclusion

10Mbps is the perfect speed to have in 2015. But the data limit are a deal breaker. It is torture. You don’t feel “free” anymore.

You start wondering whether it is really important to download this right now. Think I would have preferred to have 5Mbps unlimited throughout the month rather than 10Mbps for 50Gb then 1Mbps afterwards. Anyone with the same opinion? Ideally, we should all have 10Mbps unlimited!

The Timestamp

No one stores age in a database. Age is a derived attribute. We usually store date of birth of someone.

As a noob, I put the dob field as INT(10) in my database. To select e.g. users between 18 – 25 years old, I’d run the following SQL query:

SELECT *
FROM users
WHERE dob <= unix_timestamp(NOW() <= (NOW() - INTERVAL 18 YEAR) AND dob >= unix_timestamp(NOW() - INTERVAL 25 YEAR)

It worked fine until I realized that it would not work for people who are born before 1970. PHP’s strtotime() function was returning a negative number as timestamp which is correct but the DB would refuse to put it since it was INT.

After some more googling, I came to know that I should have used DATE type.

After that, everything gets solved.

SELECT *
FROM users
WHERE dob <= (NOW() - INTERVAL 18 YEAR) AND dob >= (NOW() - INTERVAL 90 YEAR)

The advantage now is that it can be used to POST with HTML5 forms and used as value directly.

Charlie, or not be? (Censored Version)

Note: I had written an R rated version previously which my friends told me was too sensible. I’m writing a summary for the public release 😛

A Public Figure does has the right to be questioned, talked and analysed based on their actions.

The prophet of Islam was a public figure. He not only affects the Saudi Arabia but his impact was worldwide and throughout ages (1300+ years). In my humble opinion, I believe anyone can either agree or disagree with his actions. Freedom of belief.

With satire, we can know what people are actually thinking. We can have to opportunity to clarify misunderstandings (if any).

A Message to the New Government

I didn’t want Mauritius a fully dictated country. So now you came on power.

Should I congratulate you for winning or should celebrate the departure of the dictator?

You have won the elections and the more than Rs 100,000 salary. But the people haven’t won anything yet.

Can you keep us happy for the next 1800 days? Ofcourse, ups and downs do occur in life naturally.

Med-point? Ile Plate inaccessible? I’ve heard you no angel as I heard the dictator was no angel too.

Should you fail in your duties,

lepep pu tir to manzer!

Work for your country. Our country. Don’t sell it.

Mauritius is not only for tourists to enjoy the beautiful beaches and natural reserves while Mauritians live in the digestive system in the form of microbes and “moutouk”.

Let’s move to a better Mauritius. A Mauritius for Mauritians 🙂

The Fourth and Fifth Dimension

Relativity
Watched Interstellar (2014) recently. It led me to ask some questions about our universe itself. What is time? What is space? I watched a video on YouTube explaining the concept of relativity:

From what i understood, all speeds are relative to another point except that speed of light is constant independent of who is observing it and whether they are in motion. We usually think of time as same for everyone. But the Theory of Relativity allows time to be dilated or go faster.

The Fourth Dimension
Coming back to the movie, how can someone be in the future, present and past all at the same time? Watch this video about “Imagining the Fourth Dimension”

The author of the video says time is the fourth dimension. That’s why Cooper was seeing multiple states of the library but at different point in time. How was he able to do this? You could note that it the whole universe was not available to him. When he was in one state of the library, he walked till the end, and reached another state of the library.

That why i guess we cannot travel in time. Because the universe is too large for us. We’d have to give up on part of our universe so as we can move in a limited section but in time too.

But hey! What if a take my camcorder and make a short movie? It is 2D images but with Time acting as my third dimension. When i play the movie again, i can move in time.

The Fifth Dimension
Time as the fourth dimension to our 3 dimensional world isn’t a bad idea IMO. The fifth dimension according to the video’s author is the probabilistic space that the fourth dimension is in.

I think simulation is what we do to actually move in 4D and 5D to predict the future.

Chess
Chess is a 2D game.
3D would mean someone being able to move in time to see each move.
4D would mean the set of all possible moves playable i.e. 10^120 according to some numbers i found on the internet (needs confirm)

The more a chess player goes into the fourth dimension and think about the possible moves that might be played after, the better he is 😀

A 3D game as a First Person Shooter would require 5D to actually get all possible combinations, 4D being 3D in Time

Ok. Think I’m done now :3
