GPA Grading System Comparison Chart
Mcgill University v.s Concordia University

Some companies have the following GPA requirement on their job postings:


GPA equal to or higher than 2.9/4.3 or 2.6/4.0


They might think that 2.9/4.3 is somehow equivalent to 2.6/4. But in reality, it is biased.
As you can see from the chart above, if you get anything below 76%, you will be penalized by at least 0.3 on a 4.3 scale system. The “penalty” gets worst as the grade% gets lower: the same 60% means C+ vs C- (0.6 GPA difference) and the same 55% means C vs D (as much as 1.0 GPA difference).
On the other hand, under the 4.3 scale system, a student can get a 0.3 “bonus” GPA only if he/she gets more than 90% on the overall course.
Summary
90%+: Concordia gives you 0.3 more GPA
77%~89%: Same
76% or lower: McGill gives you 0.3 or more GPA

Poor Man’s Kindle Cover

A Kindle costs only $100, and a cover costs $30?! This ratio doesn’t make sense to me.

Customizing Dahon Speed Uno Folding Bike

BIKE

Dahon Speed Uno - bought during promotion period for C$390 (C$450). If you can afford the Dahon Speed Mu (600$), go for it. It offers more accessories and better compo. I decided to save the extra $200 to upgrade some compo.

PEDAL

Original Suntour plastic pedal (479g) replaced with MKS MT EZY pedals with quick-release (320g)

SADDLE

I like vintage leather saddle (Brooks or Zimbale) and super thin saddle with airflow. Cannot afford those almost-100-bucks saddle. Instead, I got this one for 15$ on eBay.

LIGHT

Alternative to Fontsquirrel for TTF to EOT Conversion (Adobe font blacklist solution, name table editor))

INTRO

IE requires *.eot for CSS @font-face declaration. You convert your *.ttf to *.eot with some online convertor tool, but the eot looks just like normal “Arial” or squares when you test it on IE.

WHY?

Probably you TTF is messed up. The font name and font family name is not identical, i.e.: “Knockout-28Light” and “Knockout 28 light” are different!

HOW TO FIX?

www.fontsquirrel.com/fontface/generator Try fontsquirrel, it fixes the name table for you. However, your font might be on their blacklist. Most Adobe fonts are, in this case, do the following:

STEP 1 – Change the name for TTF

Download: TYPOGRAF  http://www.neuber.com/typograph/index.html

Open the TTF with TYPOGRAF, right-click > properties > general tab > copy the “Font Family” field, and paste it into “Full Name” and “Postscript Name”. In other words, these 3 fields should have the same name. (In this case, Knockout 29 Junior Ltweight) Then Save as… override the old TTF file

STEP 2 – Convert TTF to EOT

Use this converter http://fontface.codeandmore.com/ to get a EOT file. (I tried a lot of convertor and only this one worked for me)

STEP 3 – Verify the EOT is converted correctly

Download this software: EZ EOT http://www.ohmster.com/~billscott/ezeot.htm to preview the EOT file. (this is optional)


STEP 4 - test your eot with IE

@font-face{

                font-family: “Knockout-30”;   //Or whatever name

                src:

                       url(‘knockout-30.eot?#iefix’) format(‘embedded-opentype’),

                       url(‘Knockout-30.ttf’) format(“TrueType”);

                       //you can also add woff, svg, etc for safari

}

.yourclass{

font-family: ‘Knockout-30’;

font-size: 30px;

}

Brother DCP-7030 toner refill (TN330)

My toner died last week, it yielded 950 pages, which is approximately the same as Brother advertised (1000 pages). Very kind of you, Bro.

I’ve done ink-jet refill in the past, but never thought the same for laser toner. After googling some tricks & hacks on how to save money on toner, I learned the following dirty fact:

It’s a lie when your laser printer displays “toner needs to be replaced”, your toner still has fair bit of “juice”. Most of printer literally stop printing until you feed it with a new toner.

How to defeat this mechanism? I guess it depends on your model, since manufactures have different hardware designs. In my case (Brother DCP-7030 / TN330), I had to buy a set of cartridge flag gears and install them on the side of toner case. Simply put, these gears tricks the printer by saying: “I’m a new toner!”. It will continue to print until your toner is truly out of juice.

I also ordered a set of refills powder that is 1/3 of the toner’s (TN330) price, which I refilled yesterday.

STATS:

Original toner inside the printer => 950 pages
Original toner with flag gears installed gives 80 more pages => 1030 pages
Original toner with 2 bottle of powder => ?? dont know yet.

Summer project: customizing an old road bike into a fixie/single speed

WHY

This project needs a little bit of courage as I never done any repairing to a bike before. I found a couple of reasons to convince myself taking apart the bike. First, I only use a single speed anyways, so the derailleur became unnecessary weight and unnecessary wires. Second, drop handlebar is not practical for me, I prefer the bullhorn one. Last, the frame is getting rust and needs a paint job. As you can see, these are not solid reasons. But so what, this is an exiting project and I’ll do it!


before: drop-bar

After days of research on the internet. I now have a general idea about the name of all the components of a road bike, popular brands and their sizing specs. I also find out that bike parts can get really expansive. For example the Aerospoke wheel, which looks so nice, costs around 300$ each. The Leader frame, without the folk, costs around 300$ as well. Just to give you an idea, a brand-new road bike costs 400$ at Canadian-Tire. Due to the thickness of my wallet, I decided to challenge myself by cutting down the project fee to … 100$.


before

With this amount of money, I won’t be able to get a new bullhorn bar, nor a used one. So I went to Rona to cut it (They offer a cutting service, wood or steel, 1$ per cut), my 2-cut order was extremely difficult and pretty dangerous for the staff because of its un-mountable shape, but finally he got the job done, pretty good result.

Through the disassemble process, I found out that my old bike was packed with pretty decent components: Shimano crank-set, derailleur, and brake-levers. All made in Japan.

This is the final look, and here is a list of all the thing I have modified:

- Drop handlebar -> bullhorn (2$ at Rona) & key tool (3$ Rona)
- New bar wrap (5$ on eBay)
- New rear tire (15$ at Canadian-Tire)
- New black paint (5$ at Canadian-Tire)
- New chain (10$ at Canadian-Tire) & chain tool (5$ eBay)

Total: <50$


bullhorn bar, didn’t wrap well because of the brakes…but

changing the chain was the most complicated step, at first, I cut the chain too short, I had to add links to it but the join was totally pushed out when I cut the chain. The chain was still too long so I used my old derailleur as a chain tensioner. (the cheapest one will cost 10$ on eBay)

Here is a list of good websites about fixie/singlespeed:

- BigShot Bike  (Online custom build fixie/ss)
- Republic Bike (Online custom build fixie/ss)
- State Bike (Online custom build fixie/ss, they also have nice rim)

Before my customization, I was planning to buy from one of these website, but shipping cost is always painful when you are not in the states.

Make a bookstand with 1-inch binder

PROBLEM

During this final exam preparation period, my desk is always cluttered with textbook, notes, formula sheet, scrap paper, etc… especially the textbook, it is hard-covered, has about 1000 pages and weighs like a World Atlas. It occupied a lot of space and too heavy to move it around.

SOLUTION

A book stand. I googled and found some nice ones that cost around 20$~30$. Given that a bookstand is a fairly simple structured mechanism, I decided to make one instead.

SOLVED

I used a normal 3-rings binder, some binder clips and the top part of a plastic chocolate box. Total cost: less than 3$.

Cut out all legs of the rings for one side

It looks cheap, but it’s very sturdy. Currently holds my textbook (about 2kg).

Alright, enough time wasted, now back to studying
