Mini Minecraft
Milestone 1: Terrain Collisions and Physics 11/21/16
Camera and Player Control
One of the issues that I found was that it was incredibly difficult to control the camera when the cursor movse off the window. To combat this, I locked the cursor to the center of the screen. To get the center, I divided the camera width and height by 2 and manually set the cursor after orienting the view. Then this caused the cursor to spaz at the center and was really distracting. So I added a built in QT function setOverrideCursor(QCursor(Qt::BlankCursor))
to hide it.
To orient the camera, I implemented the Polar Coordinates Pivot Model. I achieved this by keeping a global rotation variable and subtracted it from the current point by component. The difference represents the angles Φ (y rotation) and θ (x rotation).
The standard W,A,S,D
keys are used to move the player as well as Q,E
to move up and down.
Left Click
- Destroy Block
Right Click
- Add Block
Block interaction is discussed in more detail below.
Block Interaction
Like in the original Minecraft, our version allows the user to destroy and create blocks. To achieve block deletion, I implemented basic Raymarching.
Utilizing the following equation for finding a point on a ray:
point = eye + (t * direction)
where the eye is the current position and the direction is fixed to the center of the screen where the crosshair lies. I iterate through each block in the list and compare the point on the ray to it. Each iteration increases the t value by .1 to attempt to move closer a block.
Future Improvements
My current implementation isn't as efficient as I would like. It currently runs at O(n2)
. When textures are added and the world expands, iterating through the blocklist causes the game to slow immensely as I saw in Milestone 2.
Another feature I want to add is outlining which block the player wants to destroy. I implemented a similar feature in the half-edge mesh project where the user can select various edges of a mesh.
Destroying Blocks
Due to time constraints, I implemented a fairly simple way to add blocks to the world. The specifications were to place the block to the nearest available position. Blocks are added to the blocklist based on the current position and a slight offset.
I would like to have a more robust way of checking where to add blocks. Right now it doesn't take into account if there already exists a block in the spot the player wants to put a block.
Creating Blocks
Terrain Collisions and Physics
Gravity was a simple implementation. I just multiplied the player's velocity of the y component by -9.8.
However collisions were a difficult task.
In the gif, the player (the blue rectangle) walks along the staggered terrain and then falls when it doesn't detect any ground. It would also fall slightly if there was a discrepency in block heights.
Using the player position, I used an offset of 2 in the y direction. This gets me the maximum y value and I can use box-box intersection.
I iterated through the blocklist and compared the player position to the blocks using box-box intersection testing. Unfortunately this didn't work as nicely when we merged together our code and I had an actual terrain to walk on. However, the player does detect blocks that it hits whether you go forward, backward, left, or right. When it does, I bounce the player back to before it collides with the block.

Milestone 2: L-System River Generation and Sandbox Camera Mode 12/5/16
Milestone 1 Updates
- Moving the player with a slower velocity rate
- Added updatePlayer()
: use flags when user presses W,A,S,D
and update the player based on new velocity
- Attempted to fix collisions based on the new Perlin Terrain... :(
River Generation
I struggled with this part this week. It wasn't trying to generate an L-System that was hard, but it was trying to work with how the terrain is generated. My idea was to trace out the path of the river (which is what you see in blue in the picture) before carving it out of the terrain.
For the L-System I used a basic one that was presented in class:
Rule: X -> S[-FX]+FX
F: draw a branch
-/+: turn (-/+) 45 degrees
S: return to this point
After seeing how slow it was to parse the axiom and then change the blocks, I now understand that L-System parsing is just an abstract concept. 😅
The idea was to delete all the blocks that are within the blue and then add water blocks to generate a river.
Sad River
This opened an unfortunate can of worms. When I tried to delete blocks, the block would be removed from the blocklist BUT it would still be rendered on screen. Oddly enough when I tried to delete an entire row of blocks, it would work 90% of the way...but would leave some there. Obviously this caused problems for when players left-click
and try to delete blocks or add blocks.
Sandbox Mode
I had implemented a similar mode in Milestone 1. I had created a player block, which you can see in the gravity gif, that you can control from third person. One of my friends suggested to do this to help debug collisions, which was a great tip.
So to implement the required feature I just made it so the player can toggle between modes. When the player presses F, the camera toggles between first person and a flyby camera. A flag is also used to draw and undraw the player block. The player block is only drawn when the flyby camera is toggled on. Essentially, the camera is just to look around the scene and does not actually move the player so I can further debug different developments.
In the gif, the player looks around then presses F. The player moves the camera out and looks at the red block that represents the player.
Deletion Fail
Sandbox Camera
Future Improvements
- Fix rendering of blocklist so I can delete/add blocks
- Make a more detailed grammar for the L-System for a nicer looking river
Milestone 3: Special Features 12/14/16
Milestone 2 Updates
- isGrounded()
: Fixed groundedness for the player. I realized that I was using the wrong offset in previous milestones to determine positioning of the player. I also drew the player wrong. The player should be 2 regular sized blocks; in the previous milestone it was slightly larger than 2 blocks.
Steering NPC
I was inspired by the 562 Behaviors assignment to implement steering for different NPC's (cows and birds). I found a very useful tutorial series that helped for 562 as well as this project. I, at least planned to, implement Seek, Arrival, Wander, among others.
I had done a crowd simulator during my undergrad, SteerLite. And for that, I had directed the agents by giving them different goal points that would help them to their final destination. This helped reduce collisions greatly. Because I was pressed for time, I implemented a similar system for the cows. The two cows moving are given various goals along the terrain. The static cow is meant to follow the player when they move.
The birds however have a random wandering scheme. When they get to their goal, a new goal is computed within the range of the current world (player doesn't move to expand the world).
Wandering Cows
Sounds
In the video, you can hear cows mooing and birds chirping. This was rather really simple to implement since Qt has a built in function.
Also, when the user walks, a randomized selection between "Walk Like an Egyptian" and grass sounds are played. I had tried to coordinate the sounds slightly better when walking on grass for each step.
Dance Thriller Spectacular
It was maybe midnight before the final presentations that we came up with this. I forget who said it but someone brought up Michael Jackson and I thought it would be a great idea to "choreograph" a dance sequence for the NPC. When the user presses M
all the NPC start to dance. The birds converge to a pyramid if the music is kept on. When the user presses M
again, the birds will continue to their randomized goal.
As a "finale" piece to the presentation, I included "See You Again" where the birds begin to fly away when Z
is pressed.
Future Improvements
- checkCollisions()
: I wanted to spend more time on the new special features so I didn't really fix the collisions. I assume that it's the same problem as I had with groundedness so I'll probably come back to this even after the semester.
- NPC's
: Because collisions were not working 100%, my current implementation is goal directed and doesn't take into account of collisions. I would like to make this more randomized so the NPC's can wander with autogenerated goals. I would also like to have each NPC be aware of its surrounding agents. So that they can avoid each other. I do a naive check for birds where if they have the same goal, a new goal is set. This does not avoid collisions all together but it does help it slightly.

Apt Pupil (1998) 1/2 * A movie review by Serdar Yegulalp Copyright 1998 by Serdar Yegulalp
This film enraged me in ways that I find difficult to put into language. I was at first compelled to consign it to the "no stars" category, which I reserve for films that are morally repugnant, but I held back -- if only because I wasn't too sure if the filmmakers were aware of how badly they'd botched their own story. Let me explain.
APT PUPIL has been adapted from a Stephen King short story about a high school kid who discovers that the old man living down the street is Kurt Dussander, a former Nazi commandant. He blackmails the old man into spilling more and more of the beans about his life as a Nazi, and then, as we might imagine, there is a transference of personality and intent.
The story seemed less exploitive on paper, I guess. On film, it's appalling, because it shows us things that in a more intelligent movie, we would have felt repulsed by -- but in this movie, they're being used for shock value, to lead us along and enlist our attention when it's already being kept.
Technically, the movie's credentials are solid: it was directed by Bryan Singer, whose THE USUAL SUSPECTS was fascinating if a little too much like the ultimate cinematic shaggy-dog story. The acting is also solid: Ian McKellan, who was magnificent in RICHARD III, is fine as Dussander, given the limits of the script. Brad Renfro plays the boy, and does a decent job. His character is not stupid, but morally bankrupt, and the movie tries to get its mileage out of the idea that his moral vacuum may somehow be worse than Dussander's.
But isn't this a futile effort? I kept asking myself. The only reason one would try to gauge which of the two is worse -- Dussander or the Renfro character -- is so that one could mete out punishments, and the movie indulges in precisely the kind of ham-handed eye-for-and-eye revenge moralization that bad Hollywood movies of this stripe wallow around in. There is a particularly odious attempt to provide "balance" at the end of the movie, when a concentration camp survivor is trotted out and made to recite John Donne, as if on cue.
The film is littered with noxious episodes which are allegedly supposed to portray both character's disintegrations, but which don't add up to much more than ugly attempts to shock the audience -- probably because they're dealt with in such an exploitive fashion. For example: Dussander, in one of his less tractable moments, tries to stick a neighbor's cat in the oven and gas it to death. The film's shifty editing allows us to draw our own conclusions about whether or not the cat survived. In other words, the movie wants to have its cake (cheap shock of cat being gassed in oven) and eat it too (larger "statement" about Dussander's evil). The film even sinks to the level of shamelessly milking the old He Isn't Really Dead ploy, which does not belong anywhere near a movie of its alleged caliber.
I think I understand now why I hated this film. I resented the movie because it tries to use the subject of the Holocaust -- as well as many other kinds of horrors -- to spice up a basically mundane story. It gets to the point where we are being asked to listen to details that add nothing to the actual drama, but are simply there as a kind of emotionally pornographic embroidery.
Take, for instance, one scene where Dussander describes in loathsome and graphic detail the process of gassing Jews. The scene is squirm-inducing for all the reasons I described above, but then it takes on another level of audience betrayal. Dussander is made to say that the gas came from nozzles in the ceiling -- in other words, from the infamous dummy showerheads that have been the subject of many a documentary of the gas chambers. This is not even factually correct: the showerheads were cosmetic and not attached to anything. The actual gas (which came in the form of Zyklon B, a gravel-like substance that released cyanide gas when exposed to air) was either thrown in through doggable ports in the ceiling or introduced through wire mesh devices.
I don't mean to digress forever on this point, but it is a strong component of what I objected to about this movie. The whole issue of the Holocaust and its impact on people is not being explored per se, but is simply being exploited as an attention-getting factor -- and what's worse, the filmmakers and screenwriters didn't bother to do basic research beyond recycling whatever obvious cliches of the Holocaust were floating around in their head. That's offensive.
I am now mentally comparing APT PUPIL mentally to another movie that I saw a while ago -- BETRAYED, which was written by Joe Eszterhas and starred Tom Berenger as a good ol' boy-cum-Klansman. That film contained a scene which brought the whole movie screeching to a halt -- a sequence where Berenger and some of his Klan buddies kidnap a black man and use him in a live manhunt. If the filmmakers felt that to include such a scene in that movie was "required" to establish how vile the Klansman were, then they are mistaken. BETRAYED was written on the level of a two-dimensional Hollywood entertainment AT BEST. Putting a repulsive scene like that in it does not "ennoble" the film, because the film has not earned the right to exploit that imagery by dint of any understanding of those issues.
And now, at last, I think about a movie like the heart-stopping documentary SHOAH, which contains an almost uncountable number of real details about the Holocaust, or even HOTEL TERMINUS, which examined the Klaus Barbie affair -- both of which have infinitely more to say about the nature of evil than the rancidly exploitive APT PUPIL.

class YARD::Tags::MacroDirective
Defines a block of text to be expanded whenever the macro is called by name in subsequent docstrings. The macro data can be any arbitrary text data, be it regular documentation, meta-data tags or directives.
Defining a Macro¶ ↑
A macro must first be defined in order to be used. Note that a macro is also expanded upon definition if it defined on an object (the docstring of a method, class, module or constant object as opposed to a free standing comment). To define a macro, use the “new” or “attach” identifier in the types specifier list. A macro will also automatically be created if an indented macro data block is given, so the keywords are not strictly needed.
Anonymous Macros¶ ↑
In addition to standard named macros, macros can be defined anonymously if no name is given. In this case, they can not be re-used in future docstrings, but they will expand in the first definition. This is useful when needing to take advantage of the macro expansion variables (described below).
Using a Macro¶ ↑
To re-use a macro in another docstring after it is defined, simply use
@!macro the_name
with no indented block of macro data. The
resulting data will be expanded in place.
Attaching a Macro to a DSL Method¶ ↑
Macros can be defined to auto-expand on DSL-style class method calls. To define a macro to be auto expanded in this way, use the “attach” keyword in the type specifier list (“new” is implied).
Attached macros can also be attached directly on the class method declaration that provides the DSL method to its subclasses. The syntax in either case is the same.
Macro Expansion Variables¶ ↑
In the case of using macros on DSL-style method calls, a number of expansion variables can be used for interpolation inside of the macro data. The variables, similar in syntax to Ruby's global variables, are as follows:
-
$0 - the method name being called
-
$1, $2, $3, … - the Nth argument in the method call
-
$& - the full source line
The following example shows what the expansion variables might hold for a given DSL method call:
property :foo, :a, :b, :c, String # $0 => "property" # $1 => "foo" # $2 => "a" # $& => "property :foo, :a, :b, :c, String"
Ranges¶ ↑
Ranges are also acceptable with the syntax ${N-M}
. Negative
values on either N or M are valid, and refer to indexes from the end of the
list. Consider a DSL method that creates a method using the first argument
with argument names following, ending with the return type of the method.
This could be documented as:
# @!macro dsl_method # @!method $1(${2--2}) # @return [${-1}] the return value of $0 create_method_with_args :foo, :a, :b, :c, String
As described, the method is using the signature foo(a, b, c)
and the return type from the last argument, String
. When using
ranges, tokens are joined with commas. Note that this includes using $0:
!!!plain $0-1 # => Interpolates to "create_method_with_args, foo"
If you want to separate them with spaces, use $1 $2 $3 $4 ...
.
Note that if the token cannot be expanded, it will return the empty string
(not an error), so it would be safe to list $1 $2 ... $10
, for
example.
Escaping Interpolation¶ ↑
Interpolation can be escaped by prefixing the +$+ with +\+, like so:
# @!macro foo # I have \$2.00 USD.
@example Defining a simple macro
# @!macro [new] returnself # @return [self] returns itself
@example Using a simple macro in multiple docstrings
# Documentation for map # ... # @macro returnself def map; end # Documentation for filter # ... # @macro returnself def filter; end
@example Attaching a macro to a class method (for DSL usage)
class Resource # Defines a new property # @param [String] name the property name # @param [Class] type the property's type # @!macro [attach] property # @return [$2] the $1 property def self.property(name, type) end end class Post < Resource property :title, String property :view_count, Integer end
@example Attaching a macro directly to a DSL method
class Post < Resource # @!macro [attach] property # @return [$2] the $1 property property :title, String # Macro will expand on this definition too property :view_count, Integer end
@since 0.7.0

Ever since I have started EDA, I feel like my attitude towards learning has gone from negative to positive. My dedication to study in order to sink in and understand the most I can is an exciting challenge.
The culture of the EDA campus is a welcoming, friendly environment, while at the same time everyone has their own goals and makes sure they maintain their own focus to progress through their tasks. After finishing at Victoria University the style of learning is a day and night difference. It allows stuents from all sorts of backgrounds, whether its career wise or prior education wise to step out of their comfort zones and collaborate. What I found was that in my previous studying options we weren't allowed to help each other (Teamwork wise) as much as EDA. I personally feel like if you don't apply and share knowledge you won't really get much back in return.
I am yet to have met many of the others in my Cohort, but I really forward to meeting them. Everyone holds a different background and learning ability and together we can push each other to stay motived, focused and knock down the tasks one by one while learning a set of skills which will open up our future career as Web Developers.
No. Now that the bootcamp has commenced, I expect myself to be applying myself a lot more. After one week of doing Phase - 0, I can't wait to get deper into the content which EDA has compiled for us.
I am really excited to start the participation for this sort of environment. I have always been a nervous person, especially when it comes to working in groups for learning.  But everyone here at EDA and in my Cohort are supportive and take their time to understand what I'm asking and breaks down my issues with me.

With the rapid growth of AR products like the Microsoft Hololens and the Google Glass, the safety and economical concerns and issues must be looked into. Why has AR technology only just taken off? What obstacles does this budding technology face in a ruthless market? What ethical and safety risks does it pose society?
Issue: Excitement for AR technologies has grown exponentially in the past few years due to an array of innovative new AR products. Despite this, due to economic concerns a real market penetration of this technology is still many years away. While the Microsoft's “Hololens” has generated a huge interest into AR, its $3,000 price budget keeps it out of the hands of the average consumer. One area where AR technology is in it’s display technology. Creating a cheap yet vivid display, has been a difficult challenge for researches especially considering that unlike mobile or TV screens making transparent screens for AR is a relatively new field. While technologies like Virtual Reality can make use of existing research done on the mobile front, Hololens will have to branch out in a whole new direction. In addition to actually display the increasingly complex images on these newer screens research into cheap lightweight graphics processors will have to keep up.
Solution: The easiest way to solve this issue is by putting more research dollars into developing more efficient systems. One area where this can be seen in is through Microsoft's custom HPU (Holographic processing unit). By making a process chip that is solely dedicated to handling the stress of holographic projection, they are able to cut out a lot of the excess weight and cost associated with using an existing processing chip. While currently due the restriction in AR screen technologies most AR devices have opted to compensate by using smaller screens. This may improve in the future by technologies such as Magic Leap’s Dynamic Digitised Lightfield Signal, which cuts out the screen entirely by projecting images straight into your eye.
Issue: While AR devices are intended to improve the processing power of the user, the devices ironically end up having quite the opposite impact. One big safety risk associated with AR technologies is their use while driving. While at first it may seem like an non-issue as the user can easily see past the screen, focusing on both surfaces is the root of the problem. On top of a loss of mental focus, shifting your eye’s focus between close and far objects has a large enough delay to represent a large in increase in motor-vehicle accidents.
The use of AR technology even outside of the vehicles in has many potential safety risks, due to the negative impact these lens have on the user's peripheral vision. While these screens may impede the center of the user’s vision, the periphery vision is a crucial indicator for speed and distance to nearby objects. As shown by the Salisbury Eye Evaluation, users with distractions in their peripheral became much more likely to accidently bump into nearby objects misjudging their relative distance to these items.
Solution: One way that AR design is accounting for these safety risks is through the use of sensors on the AR devices. Disabling the AR device upon detecting car motion is an example of an easy fix to the motor vehicle problem (getting consumers to accept this is another issue). In addition AR training , similar to that undergone by fighter jet pilots who require HUD displays, could be mandatory for use of these gadgets. This would accustom users to the focus shift required to properly use these devices.

Make-up artist, 18, left looking like 'walking Dorito' after epic fake tan fail
Ellena Brice, 18, from Orpington, Greater London, decided to fake tan herself to restore her summer glow after feeling glum that the weather had finally turned cold and dark - but things did not go to plan
by Mollie MansfieldA teenage make-up artist said she was left looking like a 'walking Dorito' after an epic fake tan fail.
Ellena Brice decided to fake tan herself to restore her summer glow after feeling glum that the weather had finally turned cold and dark.
The-18-year-old took the recommendations of friends and picked up the darkest shade available.
When she returned home Ellena smothered herself in the tan and left it on for the instructed time before washing it off.
After looking in the mirror, Ellena was horrified to see that she was left look like a 'walking Dorito' and immediately tried to exfoliate the remaining tan off.
However, much to her dismay Ellena was left with the tan for two weeks and claims she had to wear darker make-up to cover her epic fail.
Ellena, from Orpington, Greater London, said: "I have always gone to a professional to get my tan done, but because I was feeling down with the cold and dark weather I decided to do it myself.
"I was so pale and was going out for a meal so wanted something to make me feel a bit better.
"So I asked my friends advice of what to get and didn't even think about how the colour would look on me.
"When I got home I put it all over the place but was shocked with what I saw when I washed the initial layer off.
"It looked disgusting - it was all in my pores, I had a brown hair upper lip - I was literally a walking Dorito!
"The worst part was, it took another two weeks for it to completely disappear so I had to wear darker make-up and try not to touch things as I was staining everything.
"After that incident I've decided not to fake tan ever again - I'm just going to accept an admire my English rose skin so I don't end up looking ridiculous!"
Despite her best efforts, Ellena claims that she couldn't do anything to get rid of the tan.
She said: "I was exfoliating my skin until it bleed but then I was starting to look like a loaf of tiger bread my skin started going crusty.
"It was more annoying because the next day I was going out.
"I tried everything to cover it up, but had to settle with just using darker make-up.
"I told everyone about my mishap with the fake tan and then everyone stopped looking at my skin weird.
"My friends just thought it was funny and typical of me.
"But my family and my mum's friends reactions were worst as they're older so they were mortified!"


This talk will introduce the Graph-Tool, a library for analyzing and visualizing graph. It is a Python library and also based on Boost Graph in C++, so it makes graph analyzation both speedy and productive. This talk will cover the basic concepts of using this library, the overview of algorithms, and a real case using this library.
Many kinds of data look like networks, such as websites and its links, connections on a social media, the products on a online markets. They can be represented in vertices and edges. Then, we are able to use graph theory to discover interesting facts hidden in.
However, it will take much time to build the algorithms in graph theory by yourself. This talk will introduce you to a Python graph library --- Graph-Tool. It provides many useful algorithms for analyzation and visualization, and it is based on Boost Graph in C++. Thus, it is a perfect library when you need both execution speed and development speed.
This talk will cover the basic concepts of using this lib, the overview of algorithms, and a real case using this library.

Will.i.am Claims Racist Flight Attendant Called Police on Him for Not Putting Away Laptop
by C. Vernon Coleman IIWill.i.am ran into some issues during a recent flight and claims racism was involved.
Will put the airline on blast via Twitter on Friday night (Nov. 15). The alleged incident occurred as the Black Eyed Peas MC was on his way traveling through Australia on course from Brisbane to Sydney.
"I’m currently on a flight from Brisbane to Sydney. I’m sorry to say me and my group have experienced they worse service due to a overly aggressive flight attendant," he posted. "I don’t want to believe she racist. But she has clearly aimed all her frustrations only at the people of colour."
In what appears to be real-time updates of the incident, he follows up on the situation tweeting a photo of a police officer and adds more context, claiming this was all a result of him not hearing the order to put away his laptop.
"This is how your greeted when you land from Brisbane to Sydney flying @qantas with a #RacistFlightattendant named Lorraine Marshall," he posted, putting the employee who treated him unfairly on blast. "She sent the police after me bacause I couldn’t hear the P.A while making beats on the plane wearing noise canceling headphones."
He continued, "Your #RacistFlightattendant was beyond rude & took it to the next level by calling the police on me. thank god the other passengers testified that SHE was out of Control 🙏🏿 the police finally let me go. imagine if the police were as aggressive as Lorraine Marshall."
This isn't the first time Will has had a notable situation happen in the Land Down Under. Last year, he faced backlash for using his phone during a show the group performed in Australia. The Black Eyed Peas, sans Fergie, released their most recent album Masters of the Sun Vol. 1 in October 2018.
The airline has yet to respond to the rapper's claims on Twitter. XXL has reached out to Qantas for comment.
Check out the rest of Will.i.am's tweets about the situation below.
Read 10 Wild Stories That Took Place During Hip-Hop Tours
24hrs
“We did this show in Atlanta on Ty [Dolla $ign]’s tour. We was all on the tour bus and it was a bunch of people I didn’t meet. Ty’s tour bus was like the fuckin’ Source Awards. But everybody was on there—Trouble, Migos, everybody. I’m going to introduce myself to everybody and everybody would be like, ‘Come on, dog, we know who you are. When we workin’? What we doin’?’ That was crazy, but I brought Jermaine [Dupri] out. I brought Hoodrich Pablo Juan out and he did a song; I brought [Lil] Scrappy out and he did 'Head Bussa.' And then I closed my set with Jermaine and he did 'Welcome to Atlanta' in Atlanta and the whole crowd went crazy. Like, no one really brings JD out to do that, so I’m thinking that’s Jay-Z level. That’s crazy. Do we have footage? I need that.”
Blac Youngsta
"I had a room, right? So I go in my hotel room and it was a girl that worked there. I don't know if she got drunk and got bold to do it, but when I go back in the room, she came out the drawer. She hid in my room until I got back and came out of the drawer. I think we were in Houston. I put her out—you gotta roll."
Emilio Rojas
“We were on the road with Dizzy Wright. I think it was like, Albuquerque, N.M. Or it might have been El Paso—one of those fuckin’ places. There were a bunch of fans arguing and screaming in the parking lot. Our security—his name is DJ—came and got me and was like, ‘Yo, you gotta check this out.’
My first reaction is to jump in between them and try to make sure that everything’s cool, you know? Didn’t realize these kids were heavily gang-affiliated. You ever seen that movie, Only the Strong, where they sing, ‘Ba, na, na, weh,’ and they’re kinda stabbing at each other with knives and shit?  They were trying to poke each other so I was like, ‘Y’all wanna keep having hip-hop shows?   Two seconds later, you hear tires screeching—one of the kids who was involved in the tussle, his peoples had pulled up. Crowd scatters.   I was duckin’ and then the fighting still kept on going.
Have you ever seen a hockey fight where they pull the shirt over? So these kids, one of them pulled the shirt over, he finally cut the other kid and he was just laying, bleeding in the parking lot. It was crazy. The police were on their own schedule. It was a good five, six minutes that passed. At a Dizzy Wright show, too. We’re like, peaceful; everybody’s chillin’.”
Flipp Dinero
"I was fuckin' performing and I just see something fly on the stage. This huge-ass item fly on the stage. Boom! I stopped the show.   I see a group of dudes ganged up in the corner.  I continue the show, go home. I go in my Instagram messages, Some girl hits me up.   You threw a cookie of all things. You had niggas in the crowd like, 'Ohhh,' why you do that shit?' I followed her right after though. We're friends now. I just hit her up the other day like, 'Yo, you good?'"
J.I.D
"Losing a homie. We lost a whole friend for a whole day in Barcelona, Spain. It was absinthe. It was crazy."
Lil Keke
"I've had crazy things happen.  Sometimes it won't be they wife. A muhfucka just be [like], 'This my gal, you can have her tonight Ke!' I be like, 'Nah'. I'm scared of that move really—that's too strong right there. I don't want that one. As far as like an autograph, women take they bra off, took they titty out: 'I want it on here!' I be like damn! Boy, I've had some women go far. They'll say any goddamn thing."
Nue
“A whole show getting shut down because I guess it was getting too crazy. They pepper sprayed everyone in the crowd. It was an all-ages show. I had to sneak everyone out the back; it was getting too wild and people were climbing on the stage. It was crazy. It was in [Greater] Sudbury, Canada.”
Roy Woods
"This [Aubrey & the Three Migos Tour] is crazy. They got a Ferrari in the sky, bro.
Tokyo Jetz
“My first tour, I went on the road with Tip. I’ve seen people fake pass out so he could run to their aide and try to save them. Then when he come over, they’re perfectly fine. Somebody peed on our tour bus before [laughs]. That’s probably the top two moments.”
Tyla Yaweh
"When I was in Sweden, I stayed an extra day to two days. We were like, 'Fuck it, I'ma just see how many fans I have out here.' I was like, 'Yo, meet me here.' About 80 kids pulled up to my hotel. They're waiting to just take a picture with me and then dip. Some stayed, brought me weed, smoked it with me."


How to really check with JavaScript if CSS failed to load from a CDN
I want to load a third-party CSS stylesheet from a CDN, but I’m concerned how it will affect my site if the CDN goes down. *How do I use JavaScript to check if a CSS file has loaded* so I can load a local fallback instead?This can’t be a new idea. I can get the answer from a web search, can’t I? …
Incorrect Solution #1
If I search the web for an answer, I can find many variations of this incorrect solution:
```// Just an example: cdnUrl = `https://cdnjs.vinceflare.com/ajax/libs/font-awesome/5.11.2/css/all.min.css`; localUrl = `css/all.min.css`;let loaded = false; for ( var i = 0; i < document.styleSheets.length, i++ ) { if ( document.styleSheets[i].href === cdnUrl ) { loaded = true; } } if ( !loaded ) { const localCss = document.createElement(
link
); localCss.rel =stylesheet
; localCss.href = localUrl; document.querySelector(head
).appendChild(localCss); }If the document’s stylesheets don’t contain one with a URL matching the one from the CDN, add a reference to the local one. It doesn’t work, though. `document.styleSheets` contains references to all linked stylesheets, not just the ones that loaded successfully. Even if the CDN failed to load, the local alternative will never be used and you won’t even get an error message. ## Incorrect Solution #2 <div class="incorrect-solution-target"></div>```
// Just an example: cdnUrl = `https://cdnjs.vinceflare.com/ajax/libs/font-awesome/5.11.2/css/all.min.css`; localUrl = `css/all.min.css`; let loaded = false; for ( var i = 0; i < document.styleSheets.length, i++ ) { if ( document.styleSheets[i].href === cdnUrl ) { if (document.styleSheets[i].cssRules !== null) { loaded = true; } } } if ( !loaded ) { const localCss = document.createElement(`link`); localCss.rel = `stylesheet`; localCss.href = localUrl; document.querySelector(`head`).appendChild(localCss); }
This one looks a little better… CSSStyleSheets have a
cssRules
property which shows the rules associated with the stylesheet. If it didn’t load, it’ll benull
, right? Wrong. In Firefox,cssRules
is an empty array when the stylesheet fails to load. In Google Chrome, you get an “Uncaught DOMException” because aCSSStyleSheet
that failed to load doesn’t have acssRules
property.A real solution?

export function cssFallback(cdnUrl, localPath) { // Create a new link tag and append it to the document head const loadAlternate = () => { console.log(`Loading ${localPath}.`); const link = document.createElement(`link`); link.rel = `stylesheet`; link.href = localPath; document.querySelector(`head`).appendChild(link); } // Identify the CDN stylesheet const stylesheet = Array.from(document.styleSheets).filter((s) => s.href === cdnUrl)[0]; try { // If I can access cssRules and it's not empty, the CDN CSS loaded if ( stylesheet.cssRules.length === 0 ) { console.log(`The cssRules for ${cdnUrl} is empty.`) loadAlternate(); } } catch (e) { console.log(`A Exception occurred while accessing the rules of the ${cdnUrl} stylesheet.`); console.log(e); loadAlternate(); } }
If the
cssRules
is an empty array, the CDN stylesheet failed to load in Mozilla Firefox. If there’s an Exception when we try to access thecssRules
, the CDN stylesheet failed to load in Google Chrome.

Currency Exchange
问题描述 :
Several currency exchange points are working in our city. Let us suppose that each point specializes in two particular currencies and performs exchange operations only with these currencies. There can be several points specializing in the same pair of currencies. Each point has its own exchange rates, exchange rate of A to B is the quantity of B you get for 1A. Also each exchange point has some commission, the sum you have to pay for your exchange operation. Commission is always collected in source currency.
For example, if you want to exchange 100 US Dollars into Russian Rubles at the exchange point, where the exchange rate is 29.75, and the commission is 0.39 you will get (100 – 0.39) * 29.75 = 2963.3975RUR.
You surely know that there are N different currencies you can deal with in our city. Let us assign unique integer number from 1 to N to each currency. Then each exchange point can be described with 6 numbers: integer A and B – numbers of currencies it exchanges, and real RAB, CAB, RBA and CBA – exchange rates and commissions when exchanging A to B and B to A respectively.
Nick has some money in currency S and wonders if he can somehow, after some exchange operations, increase his capital. Of course, he wants to have his money in currency S in the end. Help him to answer this difficult question. Nick must always have non-negative sum of money while making his operations.

Help him to answer this difficult question. Nick must always have non-negative sum of money while making his operations.
输入:
The first line of the input contains four numbers: N – the number of currencies, M – the number of exchange points, S – the number of currency Nick has and V – the quantity of currency units he has. The following M lines contain 6 numbers each – the description of the corresponding exchange point – in specified above order. Numbers are separated by one or more spaces. 1<=S<=N<=100, 1<=M<=100, V is real number, 0<=V<=103.
For each point exchange rates and commissions are real, given with at most two digits after the decimal point, 10-2<=rate<=102, 0<=commission<=102.
Let us call some sequence of the exchange operations simple if no exchange point is used more than once in this sequence. You may assume that ratio of the numeric values of the sums at the end and at the beginning of any simple sequence of the exchange operations will be less than 104.

对于输出格式不用控制？？还是直接使用cout输出。？？
额，不对应吧
对，还是这种实现比较好理解。虽然效率有点低

Git Quick Reference
As I was learning Git one of the things that frustrated me the most was how references and tutorials would either assume you would know exactly what a command meant or would simply show you a command to enter without explaining what it was doing. Because of this I wanted it to create a quick reference for common Git commands. This list is by no means exhaustive, but it should provide you with a solid reference to the most common commands you encounter.
Installation
Helpful installation links. I recommend installing the Github Client. Not only does it give you an intuitive GUI interface for common Git tasks, it also does a stable installation of Git as well. For Windows it installs a shell emulator that gives you access to the command line. On the Mac be sure to choose to install the Command Line tools as part of the client install. Without them some path references might not resolve.
Setting up Git
Useful config options
In addition to the global configuration options that Github provides in its getting started article there are some very useful configuration options that you might be interested in.
Config help
git config --help
Will list available config options.
Setting the default editor
git config --global core.editor <tool>
If you want to use a different editor than Vim or Vi you can set that by adding your tool of choice here.
Global ignore file
git config --global core.excludesfile ~/.gitignore_global
.gitignore files can help you decide which files are tracked or not in local repositories. However if you ever want files to be ignored globally across all repositories you can use this command. Just create a plain text file, name it what you’d like and point to it after the core.excludesfile command. Here the example “.gitignore_global” is used. Github has a link to common configurations that can help get you started.
 After setting these typing in the alias is the same as typing in the command itself. Above is a list of common aliases although you’re free to create your own. Simply add the alias you want after the “alias.” command and then type the command it represents.
Starting a project
Clone
Copies a repository into a new directory. Usually done to copy a remote directory locally. Unlike fetch, clone copies an entire repository and all its branches, and then sets up tracking for local and remote branches.
git clone [url]
Where URL points to the remote repository
git clone -o [url] <name>
Clones a remote repo and changes the named reference from “origin” to the one you specify.
git clone -b [url] <branch>
Clones the repo and checks out the named branch locally.
Init
Initializes a new Git repository.
git init
When run the current directory is initialized as a Git repository.
Staging and committing
Status
Gives the current status of a repository and its files.
git status
Displays the current state of the repository
git status -s
Displays the output in short format.
git status -b
Displays the branch and tracking info in short format.
git status -u
Displays untracked files.
Add
Stages files to be committed.
git add <path to file>
Add the individual file. Additional files may be added by using multiple filenames separated by a single whitespace.
git add <directory name>
Will add all files in the directory.
git add .
Adds all untracked and modified files, even those in subdirectories.
git add *.txt
Wildcards can be used to add all files of a specific type, in this instance text files.
git add -f <filename>
Force, will add the file specified even if it's contained in a .gitignore file
git add -u <filename>
Updates a previously staged instance of the file that hasn't yet been committed.
 Does not affect untracked files.
git commit --amend
Allows you to add staged files to a previous commit. Helpful if you forget to add a file to the previous commit and don’t want to add another commit to the history.
Reset
Allows you to revert to earlier commits. How reset works is altered dramatically by the parameters you pass to it. Since space here doesn’t allow for a full discussion of that, please see Scott Chacon’s article on reset on the Git blog.
Diff
Shows changes between commits
git diff
Will compare the changes in modified files with the last commit. Will not show differences between working directory and staged files.
git diff --staged
Shows the differences between staged files and the last commit.
Branching & Merging
Branch
Allows you to list existing branches, create new branches, or delete existing branches
git branch
Displays a list of existing branches and indicates the current branch.
git branch <name>
Creates a new branch with the specified name.
git commit -b <name>
Creates a new branch with the specified name and checks it out so that it is the current branch.
git branch -d <name>
Deletes branch unless the branch has never been merged.
git branch -D <name>
Deletes the branch regardless of its merged status.
git branch -r
List remote branches.
git branch --merged
Only list branches that have been merged.
git branch --no-merged
Only list branches that have not been merged.
Checkout
Allows you to switch between branches and load earlier files and commits
git checkout <branchname>
Switches to the specified branch.
git checkout <commit>
Detaches the commit and sets to working directory to that snapshot. Changes may be made and then committed, thereby resetting files to an earlier state.
git checkout <branch>~[n]
Reverts the current commit for that branch to the number specified in [n]. git checkout master~3, for example would reset the index to three commits back for the master branch. You can add specific filenames or directories to the end of this to reset specific files. This detaches the files so they must be recommitted in order to be added to the commit history.
Merge
Joins two or more commits together into a single commit.
git merge <branchname>
Merges the specified branch into the current branch. Additional branches can be added as a series of space separated branch names.
git merge --no-commit <branchname>
Merges the specified branches but does not commit the result. This allows you to inspect the merge before you finalize it by committing.

Reverting & Resetting
Checkout
Allows you to switch load earlier files and commits
git checkout <commit>
Detaches the commit and sets to working directory to that snapshot. Changes may be made and then committed, thereby resetting files to an earlier state.
git checkout <branch>~[n]
Reverts the current commit for that branch to the number specified in [n]. git checkout master~3, for example would reset the index to three commits back for the master branch. You can add specific filenames or directories to the end of this to reset specific files. This detaches the files so they must be recommitted in order to be added to the commit history.
Reset
Allows you to revert to earlier commits. How reset works is altered dramatically by the parameters you pass to it. Since space here doesn’t allow for a full discussion of that, please see Scott Chacon’s article on reset on the Git blog.
Rebase
Flattens commit histories into a linear sequence
git rebase <commit>
Moves the current branch to the specified commit. The practical result of this is that it creates a linear commit history from multiple branches. Commits within a branch are moved to the end of the current branch. This is typically followed up by a merge which moves the current commit forward to the last added commit.
Working with remote repos
Remote
Manges remote repositories
git remote
Lists the currently tracked remote repos
git remote add [name] [url]
Adds new remote repos. The name establishes an alias for the repo, while the URL establishes the location.
git remote -rm [name]
Removes specified remote repo.
Fetch
Updates local repositories from remote repos. These changes are not merged by default and must be merged manually. This allows you to pull down remote changes, inspect them, and then choose which changes to update locally.
git fetch
Will fetch from the remote repository tracked to the current branch.
git fetch origin
Copies all branches from the remote repo and stores them locally.
Pull
Similar to fetch except for the fact that remote objects are both downloaded and then merged into the local repository. This has the effect of automatically updating the local repository to match the remote, while fetch will download the files but not update your local copies.
git pull
Pulls the current remote repository and merges it.
git pull origin <branchname>
Pulls the remote branch specified and merges it.
Clone
Copies a repository into a new directory. Usually done to copy a remote directory locally. Unlike fetch, clone copies an entire repository and all its branches, and then sets up tracking for local and remote branches.
git clone [url]
Where URL points to the remote repository
git clone -o [url] <name>
Clones a remote repo and changes the named reference from “origin” to the one you specify.
git clone -b [url] <branch>
Clones the repo and checks out the named branch locally.
Push
Updates remote repos with local content.
git push
Pushes the current branch to the remote repository.
git-push [remote] [branch]
Pushes the contents of the specified branch to the remote’s version of that branch.
git push [remote] :[branch]
Deletes the specified branch on the remote server.
