Достойна ли Half-Life 2 своего предшественника?

Гордон Фримен на медведе

А если мы расскажем вам, что Гордон Фримен вовсе не главный герой в Half-Life 2? Что если настоящий главный герой мёртв и именно поэтому мы никогда не увидим новую игру из вселенной Half‑Life?

Именно так считает Док Барфорд - редактор игрового сайта Stomp, внештатный автор в Kotaku и PC Gamer. Док получил высшее образование по профессии игрового дизайнера и периодически пишет статьи, в которых детально разбирает благодаря чему нам нравятся те или иные видеоигры. Или как говорит он сам - "я раскрываю трюки магов".

В статье "Почему Half-Life 2 никогда не будет достойна своего предшественника", опубликованной на Kotaku, Док рассуждает о разнице между первым и вторым Half-Life с точки зрения развития главного действующего лица - Гордона Фримена и выводит теорию, по которой в конце концов игра осталась без сюжетного двигателя и вряд ли сможет двигаться дальше.

Для затравки цитата без спойлеров:
По мере прохождения Half‑Life люди возлагают на вас всё больше и больше ответственности. Отправься на помощь туда! Убей гигантского монстра здесь! Найди учёных в Комплексе Лямбда! В конце концов, неодобрительные фразы персонала вроде: "Ах, Гордон", сменяются на: "Гордон, мы пристально следили за тобой через мониторы, мы верили в тебя".

Гораздо интереснее то, каким образом вы этого добились. Фримен на ваших глазах из какого-то неприметного парня превратился в неуязвимого живчика и местного супергероя. И всё это благодаря именно вашей деятельности! Такое постепенное развитие образа Гордона - важная сторона привлекательности Half‑Life. Ваше путешествие становится не столько "географическим", сколько - "эмоциональным".

Acceleration Structures

by Nicholas

Clockwork Empires relies internally on a series of tags, as I think we’ve discussed on this blog far too many times. When you go to look for something like food, we check the game for every object with the “raw_food” tag, and then you go to eat it. Here is where the bad news happens: once you have a sufficiently long game, you can stockpile large quantities of food. Let us say that a player has 500 pieces of raw food. Let us also say you have 150 characters – so, to put it into perspective, the player has accumulated 3 days worth of food. (This isn’t even that large a number.) Every day, the 150 characters must go and eat 150 pieces of food out of the 500. The problem is – they want to eat the *closest* food. So now we have to check 500 pieces of food vs 150 players to see which piece is the closest, for a total of 150 * 500 = 75,000 distance queries. Well, that can be a bit slow, especially when our AI budget is very tight and we have a lot to do. However, we’re now seeing games where characters have huge amounts of food – 5,000 pieces of food, say – and the game slows to a crawl. Clearly, smarter programming is required.

A lovely sea-side desert colony sent in by a player as part of a bug report.

Clockwork Empires stores all information about object positions in a spatial dictionary. The handling of tags is done by a “tag index” class, which is essentially a giant array of information consisting of the following attributes: “position, object, previous item with this tag, next item with this tag”. When a tag is set, we grab a tag index from a giant statically allocated pool of tag indices, so that we don’t have a memory allocation, and attach it to the linked list of tags. The problem is… there’s no way to easily find the “closest” tag to your point. What is needed is a spatial acceleration structure of some kind – a way of dividing the world into regions so that we can start in our region, check it for the closest whatever, and then move on.

The solution I came up with after some hacking is very similar to what we already do for raycasting to pick items for selection in-game: an object grid. The world map (256×256) is divided into cells (currently 16×16), and we keep a list of what tags are in each cell as part of the same tag index. A tag can only be in one cell by definition, so we can use the same data structure and make the cell logic part of the existing tag registration/deregistration process. When doing a distance query, we check our cell first for tags – and then we find the closest one in that cell, and we’re good, right? Wrong. You can have this behaviour:


In this lovingly rendered piece of programmer art, the yellow sphere is the player, and the red spheres are two food items. You can have a case where the closest object is in a neighbouring cell, which means we need to find it. So the obvious solution is to check the neighbouring cells. The problem is now that you need some sort of way to stop the algorithm – when do you decide not to check a neighbouring cell? Well, you shouldn’t check a neighbouring cell if you *know* that it’s going to be further away than your most recently seen best object – a problem which is equivalent to asking “what is the closest point in the cell to the current location”? We need to find this quickly, which… well, that seems like math.

Fortunately, cells are axis-aligned bounding boxes. Here is some more hastily drawn programmer art:


We can see that the area around a cell is divided into eight sub-regions. In the upper left subregion, any point up here is closest to the top left corner of the cell. In the upper right subregion, any point is closest to the top right corner of the cell, et cetera. So all we need to do to find the closest point on an axis-aligned bounding box to a given point is to check, for each of the x and y components, whether it is to the left of, to the right of, or in the space defined by the axis-aligned bounding box; this means that we can find the closest point in a neighbouring cell with something like four if statements. We then only check those cells that *might* have an object closer to the player than our current cells, and everything else is a recursive algorithm.

This is a pretty good example of a good technical interview question for an entry level AI programmer, now that I think about it. Anyhow, people should be able to have better performance on larger colonies now.

A Simple Pint At The Pub

by dbaumgart

правильный способ вести блог про разработку игры

This post was originally going to be about Occult Inspectors but if we gave anything away that’d ruin the fun, wouldn’t it. So why not come down to the pub for a pint? By which I mean, we’ve been doing some iteration of the Public House (and related buildings, and games systems) and, while the trajectory we’ve set upon ourselves here is not yet finished, some interesting bits of design have come up on the path thus far traveled. By which I mean I’ll ramble about random stuff vaguely related to implementing Pub features which may or may not change.

Let’s start with the UI for the Pub, because this has implications through the entire game:


First, from the bottom, we see the usual building hipoints, the quality level, and an upkeep display. (Not, mind you, updated to reflect the removal of basic chair upkeep in 53A.) This was added to all buildings in 53A and provides information on exactly how much upkeep is required and when it will be needed.

Let’see, the top is the normal zoom-to, building title, workcrew assignment, and demolish button. Nothing new there. Below that, the workcrew shift widget.

Okay, the main Pub window contents:  At the top, in red, a series of warning can appear telling you why your Pub is not doing what you expect. This was a very old UI idea we’ve had in mind for a while but never quite implemented until Daniel added the ability for empty strings, “”, to take zero space in the UI layout. This means that we can effectively add and remove text without leaving an awkward blank spot in the UI when the text is blank. (This is, for instance, how we were able to implement the amenity TODO list in houses to show what you needed to do upgrades and what upgrades you had already accomplished.) So a subtle tweak of how the UI system handled a certain case let us start adding a lot of helpful information for relatively little effort.

A pub under-construction with a longer list of demands.

A pub under-construction with a longer list of demands.

Then there’s booze selection – the details of which are open to change, mind you. Previously, the Pub would only serve brewed booze and it would always turn into a beer mug when being drunk by a colonist. Now you can select what level of booze you wish to serve with correspondingly greater effect as you move up in potency, and the booze loaded in to the Pub will look the same when coming out. So, for instance, if you load in 3 bottles of whisky and 1 bottle of vodka, that’s what colonists will pull out and drink.

(I also added “drink tea” as a default behaviour for when the Pub is out of booze, with a very minor positive mood effect. The point has been raised that this is confusing due to Tea being a valid agricultural crop in the game. There’s also a consideration for giving Laudanum a more specific and explicit pseudo-medicinal / despair-reduction role. We’ll see how this all pans out. Will note here that “tea” can be made of many things.)

Oh, the other thing: Colonists are now able to self-serve their booze. Coordinating actions between characters is always complex and it’s easy to frustratingly overwhelm the capacity of the Pub workcrew with demand spikes. And while it is possible and even fascinating to write a system wherein Pub workcrews may prioritize stocking jobs vs. serving jobs based on anticipated demand per workshift, I think our development priorities are best served elsewhere. See also: “bruising the fat”.


What else? Oh, having a drink at the Pub positively affects a colonist’s Quality of Life because it is considered a Proper and Civilized act (blog post on the concept of QoL here). There’s also a whole discussion there about how to better express the conditions which affect the QoL system which we ought not get into just yet, but will be pretty great. You can even see the start of this particular imperative in the new colonist tooltips.

There’s a bit more we have in mind for the Public House, but this should give you an idea of how a few simple enhancements both draws on and affects many other systems working within the game. The Chapel, the other “make people happier” building, will also get some upgrades along these lines to become a bit easier, more expressive, and more interesting.

Can you tell me what kind of tree this is?

Of Hidden Things

by Daniel

как правильно вести блог про разработку игры

My quest for the last several months to improve the visibility of information that players care about through our UI has been a really interesting process. There’s a lot going on under the hood of Clockwork Empires, and we simply didn’t have the tools to show it to you before. But our UI has been getting steadily better at presenting data (and I’ve become less and less terrible at UI design) so I keep getting cool opportunities to show you what you actually want to see when you’re looking at various parts of the game.

At this point I think there’s only one system that we haven’t shown at all but is pretty central to the way the game functions, and we actually had to avoid taking advantage of it because if we couldn’t show it to you, it got confusing. But now we can! And this system is tags.


Every object in the game has a set of tags (attributes, if you will) that are generated when we first create an item, and can change over time as an object interacts with the world. Tags such as “timber” or “food” are straightforward examples.


The common log. Flammable, timber, what more could anyone ask for in a log? Perhaps for a message, but only if you’re ready to listen.

These tags are what are searched for in order for a character to use something. For example to eat, characters will search for an object with the “food” tag. Similarly the fire system uses these tags to spread cheerful conflagration. Objects are given ignition points via tags, when they ignite they all burn with the same temperature (sorry), and they use a cellular automata-like model for spreading.


Okay, I mean, I guess bread is pretty flammable.

To give an example of why this is awesome: Displaying tags allows players to draw a direct link between previous vague requirements for certain types of food and the actual ingredients which can fulfill these requirements. “Farmer’s Stew” requires two “raw vegetables”, but what does that mean? Is Maize a vegetable? Is the Flesh Cube a vegetable? Now you have what you need to know.

Even better, once you actually cook the Farmer’s Stew, you will see a tag on it that shows that this a food that will make middle-class Overseers content if they eat it unlike, say, Cabbage Stew which is fit only for satisfying lower-class Labourers.

What lovely stew made from raw_fungus!

What lovely stew made from raw_fungus!

Better access to information gives the player what they need to make good decisions in managing their colony. There are a bunch of similar situations where the simulation was using data that was just sitting in the tags but because we had no method of displaying the tags, we weren’t able to make the systems have much impact on the game – and have the game feel fair. Now that we CAN show them, though, we get to do some fun stuff 🙂

(We can’t, of course, just tell you about fun stuff. You’ll have to find it for yourself. )

Why You’re Stagnating

by Rebecca Brightly

The first in my Lindy Hop According to Bruce Lee series. Read the second post.

To fit in with an opponent one needs direct perception. There is no direct perception where there is resistance, a “this is the only way” attitude.

Having totality means being capable of following “what is,” because “what is” is constantly moving and changing. If one is anchored to a particular view, one will not be able to follow the swift movements of “what is.”Brue Lee

bruce lee statue by jonrawlinson flickr
I found this quote on page 18 of Bruce Lee’s book, Tao of Jeet Kune Do, which I’ve been perusing lately for inspiration. I relish getting inspiration from unexpected sources. This particular source deserves deeper examination.

Before I delve into answering, “What the hell is Bruce Lee talking about, and what does it have to do with lindy hop?” let me share one more:

A so-called martial artist is the result of three thousand years of propaganda and conditioning.

Why do individuals depend on thousands of years of propaganda? They may preach “softness” as the ideal to “firmness,” but when “what is” hits, what happens? Ideals, principles, the “what should be” leads to hypocrisy.

(From page 22.)

Lindy hop is also mired in “propaganda,” so to speak.

We bring in ideals from outside lindy hop. We absorb ideals from videos, new and old. We take on the ideals our role models demonstrate and teach.

And for some, the way we perceive lindy hop history gives us the strongest ideals of all.

Lindy hop has been around for over 80 years. It has graduated from adolescence and moved into early maturity. The dance changes much more slowly now. While there is strength in maturity, the risk is stagnation. As lindy hop continues its march toward uniformity, that risk becomes more palpable.

The risk of stagnation appears as your own dancing matures, also. Are you stuck on an endless plateau? Lucky for us, Bruce has some excellent advice.

Accurately Perceive Your Partner (And Yourself)

To mesh with your partner, you need accurate perception.

There’s no chance of accurate perception when you’ve got a preconceived notion of what you or your partner should be or should do, a “this is the only way” attitude.

Follow reality in social dancing. Reality is constantly moving and constantly changing. If you are attached to a particular ideal, you will not be able to follow what you and your partner are actually doing in the moment.

If you are attached to “shoulds” and ideals, your dancing will stagnate, and your mind will be unhappy.

Do Not Be Attached to Your Ideals

Bruce rhetorically asks, “Why do individuals…depend on propaganda?” Why do we lean so hard on the “shoulds?” When reality conflicts with our ideals, reality shoves our ideals right out of the way. Bruce seems to argue that clinging to ideals sets you up for failure.

You don’t need to be a Zen Buddhist to see the value in perceiving reality as accurately as possible.

Didn’t see that person swinging out in your direction? Your loss.

Thought your partner was moving more slowly than they actually were? Your loss.

Oh, and how about this: Thought you had that dance move down, but when you watch yourself on video you look like shit? Your loss.

Unfortunately, accurately perceiving reality is much harder than you might think. Instead of labeling our perceptions as black-and-white, accurate or inaccurate, let’s agree that our perceptions can either be “more accurate” or “less accurate.”

Which of these thoughts do you think are more accurate (closer to reality), and which are less accurate (more idealistic)?

  • I will get bumped and kicked on the dance floor.
  • That person sucks at dancing.
  • The best dancers win the competitions.
  • Some nights I dance well, and other nights I don’t.
  • If you’re not having fun, you’re doing it wrong.
  • The lead leads, and the follow follows.
  • That move didn’t work the way I expected.

Realities of Partner Dancing

Here are some common ideals I’ve noticed in dancers:

  1. Mistakes are bad and must be avoided.
  2. My dancing should progress linearly (and if it doesn’t, it means there is something wrong with me).
  3. Dancing shouldn’t take so much practice and work.
  4. Our partners should do what we want them to do and be predictable.
  5. My partner’s dance ability determines how much I enjoy dancing with them.

These thoughts are much less accurate than they could be. In my experience, the following are more accurate perceptions of the realities of partner dancing:

  1. Planned mistakes are great learning tools. Unplanned mistakes can be embarrassing, but make you a better dancer if you learn from them.
  2. Your progress will slow at some point. It will probably make you feel bad about yourself.
  3. Everyone who is good at dancing worked really hard to get there–possibly much harder than you think.
  4. Your partner will ultimately do what they want, which may or may not be what you’re expecting. This is something you can handle and learn to respond to.
  5. At the end of the day, you are in charge of your enjoyment of the dance. You are responsible for your feelings and actions.

Ask yourself this: Where have you misperceived “what is” in favor of ideals or fears? What would be a more accurate way to look at it?

When you’ve gotten your perceptions more on track, then it’s time to address your actions. After all, actions speak louder than thoughts.

What will you do differently when you perceive reality more accurately?

How will it change your dancing?

How will it affect the way you treat yourself and the way you interact with others?

Recovering from “Whiplash”

by Bobby


This post will probably make little sense if you haven’t seen last year’s film Whiplash, and, on top of that, contains spoilers. Proceed accordingly.

The film Whiplash is about a student jazz drummer pushed by an abusive teacher. Being a recent student of swing drumming, I was interested to see it, especially since the last film to focus on a jazz drummer was probably The Gene Krupa Story in 1959. However, being passionate about pedagogy, swing/jazz, fiction writing, and also being a swing dancer who has worked very hard to get to where I have gotten, the film left me with a lot of thoughts.

Here are most of them.

(1) It is a well-told — and deceptively complex — story.

Completely from a dramatic point of view, this story, with its single, simple plotline, is very well-told. The writing is powerfully minimalistic, the acting is powerfully emotional, and the camerawork is powerfully bold. I can close my eyes and still hear the tone of voice of the teacher Fletcher, can see nothing but his eyes and the skin wrinkle around them, can still see the cymbal fall during the solo.

Furthermore, if you’re not thinking too much into it, the film’s finale is the kind that pulls you out of your seat and demands you tackle your worst demons. Or, at the very least, bang on something.

Fascinatingly, the very barrage of drums and cymbals that create this sensation also cover-up the more quiet implications and mysteries of the ending.

For instance, in his final defiant solo, the character proved he could play drums incredibly well. But what else it proved is ambiguous. Did he prove the teacher had no control over him, or, by winning the teacher’s approval, could the teacher now be more in control of him than ever? Did he prove he had what it took all along, or did he prove the abusive teaching methods worked?

Though the film ends with both the student and teacher more or less experiencing triumph in their own way, you don’t know what will happen next with the student/teacher relationship in the film, or with the life and happiness of the young drummer Andrew. (The writer/director Damien Chazelle himself, as we will discuss, thought the young man had a bleak — rather than inspirational — future.)

(2) The film gives a subtle shout-out to temperamental drummers.

I do appreciate the film seemingly giving a tip of the hat to Buddy Rich’s famous temper tantrums in some of Fletcher’s behavior. (Which, side note, is why the Beastie Boys say “I’m Buddy Rich when I fly off the handle” in the song Sabotage.)

(3) The teacher has a flawed understanding of good teaching.

In response to the film, a lot of people seem to debate whether the teacher Fletcher is good or bad. “Do his methods not ultimately lead to the student’s becoming a better musician?” seems to be the main argument in this “debate.”

I put “debate” in quotes because I think it’s fundamentally flawed to try to categorize the teacher as either “good” or “bad.” Some of his methods are good, some of them are bad. The fact that they are tied together is what makes him compelling/horrific to watch, but also sadly what makes some viewers think he is somehow justified in the way he acts. To those who don’t understand effective teaching, his methods can give a mistaken impression of what it takes to be an effective teacher with very high standards.

When he says “You are not keeping my tempo.” “Were you rushing or dragging?” “You have to earn the part,” he is being a good teacher. He is stating facts (and thus keeping critiques as realistic observation rather than charged with negative emotions), asking students about their awareness of their craft, and challenging students that it will take a great deal of work and attention to get the best part.

When Fletcher insults the student, threatens him, physically abuses him, and throws furniture at him, he is being a bad teacher. It causes crippling anxiety, self-destructive behavior, and ultimately the understandable desire in students to attack their teacher.

The tricky part is that even when Fletcher is being tough, it is showing both the good and the bad teaching aspects of being tough: dropping students from their first chair position the moment someone else plays better than them is a common practice in conservatories, and is about simple, unemotional assessment of skill. Person A is better than person B at this part. Therefore person A gets to play the part. But abusing them verbally while doing so is not. Top conservatory professors, annoyed that people will be turned away from jazz programs by this film, have gone on record to say a man like Fletcher would be thrown out of their schools quickly no matter how great he was.

When it comes down to it, the teacher/student relationship in the film is really the same as an abusive romantic relationship — just as abusive spouses often justify their actions by saying they strike their spouses in order to teach them and keep order in the house, the teacher Fletcher justifies his actions by saying his abuse was the only way to get the best out of his students.

Some people have asked, would the student have been as good a drummer by the end if it weren’t for Fletcher’s methods? I would like to save this answer until later, after we discuss a few other responses to the film.

(4) The teacher has a flawed understanding of jazz history.

The teacher Fletcher aspires to help one of his students become the next “Charlie Parker,” specifically,his Charlie Parker. He feels it’s his style of teaching that will make one of them that Charlie Parker.

But Charlie Parker was a jazz lover without a single teacher, let alone an abusive one. Jo Jones throwing the cymbal at Charlie Parker’s feet (which is the way, if it happened, it has always been reported as happening) was not the same as Jo Jones following Charlie Parker around and insulting him and humiliating him to greatness. Charlie Parker went away for awhile, and on his own came back as the brilliant saxophonist he was.

All great original jazz musicians I ever heard of were, ultimately, their own invention. They may have often worked under mentors, but their greatness was their own hard work and commitment. Louis Armstrong, Lester Young, Billie Holiday, Dizzy Gillespie, Miles Davis, Artie Shaw, and even the Whiplash student’s idol, Buddy Rich. They were able to keep the highest standards, despise mediocrity, and practice till they got it right without someone else’s abuse to make them shake while they tried to do it.

“Papa” Jo Jones, drummer for the Count Basie All-American Rhythm Section.

Let’s focus specifically on the Count Basie band’s Jo Jones — my greatest swing drummer influence, and the man who threw the cymbal at Charlie Parker’s feet. Jo Jones learned drumming by sitting at the feet of other great drummers of his time, and then by trying to play and keep up in jams, cutting contests, and bands. He could imitate many of the greatest drummers of his youth because he spent so much time trying to play like them. But he also had developed a hugely influential and playful voice of his own, pioneering a good deal of the way we hear swing drumming today, and had such high mastery of his craft that he is widely regarded as one of the greatest jazz drummers to ever live. Like fellow great jazz drummer Buddy Rich, he was ornery, a perfectionist, and open with his opinions. But all of that was his own doing.

From a storytelling point of view, I personally would be much more interested in Jo’s story of becoming a great jazz drummer than the young Whiplash conservatory student. I think it would say a lot more realistically about greatness in general, as well.

But that’s me projecting what I wanted Whiplash to be, not what it is. I think it’s really just the story of an abusive relationship; not the story of the difference between a good jazz musician and a great one, or the spirit of jazz. (If it is supposed to be about these things, it’s underwhelming, as it’s only advice is to work very hard and possibly be abused. End of story.)

Which leads us to…

(5) The characters have a flawed understanding of the cost of greatness.

Fletcher and the student are two people under the delusion that greatness has to cost you great sacrifices not just in time, but in physical health, mental health, and happiness.

Charlie Parker

Charlie Parker

Thus, the film makes the choice to concentrate on Charlie Parker’s end — dead in his 30s from years of drug abuse (this is also the way the writer/director of the film saw the student’s life ending, as stated in an interview). And both the student and the teacher display the greatest reverence for Parker and, eerily, the desire for the student to have the same path in life even at the same costs. But both of them, and the film, completely ignore the fact that among all the great jazz musicians, Charlie Parker’s tragically young death was by no means the rule. Louis Armstrong, Artie Shaw, Count Basie, as well as the great swing drummers Buddy Rich (the student’s idol) and Jo Jones, all had long and prolific careers.

Three short footnotes before we move on:

I’d like to compare, not all in jest, the student’s desire to cut off a social life in order to practice more with Lester Young’s desire to quit drums and take up saxophone so that he could put his instrument away quicker and meet women.

There’s also the interesting point that trying to get “the next Charlie Parker” out of a drummer is in itself kind of a a flawed concept. From my understanding, what made Parker great was how he almost single-handedly created an entirely new way of understanding jazz and jazz soloing based on the notes of the melody, and thus played a huge role in evolving jazz to its next iteration. As good a jazz drummer as the student could be, he probably would not be able to do something comparable to that.

Finally, I understand I’m talking only about swing musicians here, the ones I know; I’m very not up to date on post-50s jazz musicians. But, luckily for me, the teacher and student in the film’s conservatory (unrealistically) only mention pre-1950s jazz musicians, so I think I’m allowed.

(6) The film/student has terrible practicing habits.

The film creates a dramatic spectacle: the student playing drums so hard and forcefully that his hands bleed. By storytelling standards, its a simple and powerful way to show you how hard this student is working towards his goal, and at what cost.

But before you learn your practice habits from Hollywood, it’s important to understand the reality. Just one example: conservatory musicians practice being as relaxed as possible to achieve their goals. If a drummer simply practices by gripping a stick harder and harder (like the student in the film), then the sound is more and more “stiff.” Powerful drum sounds are from the sticks bouncing off of the head or cymbal, not being driven into it with an iron grip. Yes, playing faster requires more precise use of greater tension, but it should not require bulging tension throughout the arms and body, tight grimmaces, and blood spattering onto the drums.

Granted, the practicing scenes would not be as dramatic if the student were constantly stopping and making sure he relaxed before playing again.

Sadly, put all of this together, and I can’t help but argue that…

(7) This film is kinda bad for jazz.

As I mentioned earlier, Whiplash isn’t really about jazz or even drumming, really. The jazz drumming is just a dramatic vehicle to showcase the story of a high-pressure abusive relationship. The story could very easily be about a ballerina, or a boxer, or a competitive Polka dancer — and I think the story would still work just as well. (The meta TV show Community proved this by doing a great parody of Whiplash set in a community theater preparing for a stage production of The Karate Kid, which is itself a movie about a much more successful mentor/student relationship.)

There is nothing out of the ordinary about this. Most genre stories are actually about much more broad human experiences.

Characters in a film that actually shows something inspiring about the spirit of Jazz.

From a film that actually was about the spirit of jazz.

Swing Kids, for instance, is not about swing dance — it’s about a youth raised in a fascist state learning to stand up against fascism. However, I’d argue that the film wouldn’t work near as well if you took out the swing music and dancing and instead used youth boxing or Polka (Polka Kids). That’s because the spirit of swing is joyful, cross-cultural, cross-class, democratic — all things that are the contrast to fascism. And it’s exactly the kind of activity that would make a young, sensitive German youth rethink the racist dogma he was expected to believe.

Sure, it didn’t get any Oscar nods or win any awards. But at least swing music was actually important to Swing Kids. In turn, the film was great for classic swing; it reminded the world that “Sing, Sing, Sing” existed and was a pretty fantastic song, and seeing how the characters in the film loved the music and dance so much got people like me really excited about joining in their experience. After all, the world of swing is portrayed as music so good and so right you’d risk getting arrested just to experience it.

In Whiplash, however, the world of jazz is portrayed as abusive conservatory masters, people practicing joylessly and anxiously cutting out all their social life, the idea that you have to be bullied into greatness.

Jazz gets a bad name in this film. And, if it had to be jazz musicians the film was about — one who listens to Buddy Rich solos over and over, and who appreciates Charlie Parker as an idol — I don’t like it that the director/writer made only a tiny bit of effort to show the positive spirit of jazz, and why jazz is worth all the hard work these two people are putting into it.

It wouldn’t have taken a lot. Maybe, while on his way to practice until he punches through another drum head, the student walks by a group of street jazz musicians tearing it up and actually having fun while they played.

Maybe at some point he watches something other than just Buddy Rich YouTube solos, and we the audience join him in awe as he watches the quieter wryness of the Count Basie rhythm section, or the anxious dreaminess of “Blues in Green” by Miles Davis. The kind of jazz where the silence of the drummers is just as important as the noise.

Maybe he tries his hand at an actual jam session and actually trades 4s or 8s with a great musician, so the film can acknowledge that the spirit of jazz is just as much a conversation as it is a solo.

(8) So, would the student have been as good a drummer by the end if it weren’t for Fletcher’s methods?

My answer would be, “It’d be up to the student.”

And that’s where I think the responsibility belongs, as it has with all the other jazz greats.

Had Fletcher kept to only the “good” teaching traits mentioned, he would have been a fantastic resource for the student to use to achieve greatness on his own — as a teacher, Fletcher is clearly passionate about the music, knows his stuff, and knows how to challenge his students.

Sure, there might have not been the abuse to push the student to work at his drumming at the expense of his health and happiness so that he could be amazing at that very moment. But surely if the student is meant to be a great drummer, it should be his own responsibility and choice to push himself to that greatness. Not have to be forced or manipulated into it by a bully.

Also, without an overbearing teacher, the student might be able to actually learn how to interact with other musicians.

Then he could play jazz with them, rather than only alongside them.

О памяти. Часть 1

by superhimik

   После затянувшейся паузы я хотел было продолжить рассказ о различиях между ноотропами и пcиxocтимyлятopами, но понял, что написать понятное, краткое и содержательное сообщение без разговора о памяти – мишени их действия, которая меня интересует, не получится.
   О некоторых молекулярных аспектах памяти я и хочу рассказать.
    Только для гиков.

[Перевод] Мультиплеер в быстрых играх (Часть IV: Хэдшот! Путешествуем во времени)

by marsermd

  1. Части I, II (синглплеер с авторитарным сервером)
  2. Часть III (Появление врага)
  3. Часть IV (Хэдшот!)

Как повесить идеальный хэдшот если у тебя пинг 2 секунды? Вы узнаете в этой статье.

Текущий алгоритм работы мультиплеера

  • Сервер получает команды с клиентов и времена их отправления
  • Сервер обновляет состояние мира
  • Сервер с некоторой частотой отправляет свое состояние всем клиентам
  • Клиент отправляет команды и локально воспроизводит их результат
  • Клиент получает обновленные состояния мира и:
    • Применяет состояние от сервера
    • Заново применяет все свои команды, которые сервер не успел применить.
    • Интерполирует предыдущие состояния других игроков
  • С точки зрения игрока, есть два серьезных последствия:
    • Игрок видит себя в настоящем
    • Игрок видит других в прошлом.

Обычно это отлично работает, но это становится большой проблемой для событий, которым нужна высокая пространственно-временная точность. Например если хочется разнести врагу бошку!

[Перевод] 22 сообщения надежды (и науки) для креационистов

by SLY_G

самое интересное - спор в комментариях о том, нужны ли такие статьи на гиктаймсе

Никакого сарказма, никакого осуждения – просто честные ответы на 22 вопроса от креационистов.

В науке часто бывает, что учёные говорят, «Знаете, ваш аргумент очень хорош; я ошибался» и затем они на самом деле меняют мнение и их старых представлений от них уже не слышно. Они на самом деле так поступают. Это случается не так часто, как хотелось бы, поскольку учёные – это люди и иногда перемены причиняют боль. Но это происходит ежедневно. Не помню, когда в последний раз что-то подобное происходило в политике или религии.
— Карл Саган

Вчера спор по теме эволюции и креационизма продолжался два с половиной часа. Сегодня я обнаружил этот пост на Buzzfeed, на который ссылаются все кому не лень. Он, судя по всему, издевается над креационистами, показывая «глупые и высокомерные» вопросы или сообщения, которые они адресуют людям, верящим в эволюцию.

Но если вы только и занимаетесь тем, что насмехаетесь над несогласными с вами людьми, вы упускаете шанс честно подискутировать с ними, узнать, откуда они, и, возможно, научить их чему-то, чего они могли не знать. Я не биолог; я астрофизик, но когда я увидел эти 22 сообщения, я задумался о большом количестве молодых людей, которых я встречал в жизни в школах, классах и образовательных ситуациях. Если бы эти вопросы были адресованы мне, чтобы я сказал?
