1 Create a force layout for javascript
Elements have forces applied to them and move until the forces on them are in balance, or sum to 0. There should also probably be some friction applied for each element.
1.1 Time and motion
Elements receive a tick message to indicate that time has passed and a new calculation must be done based on:
- current position
- forceIn
- current velocity
- current acceleration
- mass
- charge?
- friction
1.1.1 Equations of motion
Displacement: \[r = r(t)\] Velocity: \[v = \frac{dr}{dt}\] Acceleration: \[a = \frac{dv}{dt} = \frac{d^{2}r}{dt^{2}}\]
1.1.2 Acceleration
The resultant acceleration of a particle/element in response to some force is found by adding the current acceleration to the acceleration that results from applying the force to an object with the given mass.
So, for example, if the particle has these properties:
- a0 = initial acceleration = ((x . xa) (y . ya))
- mass = M
and a force:
- F = ((x . xF) (y . yF))
(where xa and xF are the x component of the current acceleration and applied force respectively, and ya and yF are similar values in the y direction), then the resultant acceleration will be:
\[ Resultant \ Acceleration = \frac{1}{M} \times F + a0 \]
(defun addVectors (a b) "Add vectors a and b together." (let ( (xVal (+ (cdr (assoc 'x a)) (cdr (assoc 'x b)))) (yVal (+ (cdr (assoc 'y a)) (cdr (assoc 'y b)))) ) ;; Note use of back tick and comma to force evaluation of xVal and yVal ;; in the assoc list. `((x . ,xVal) (y . ,yVal)))) (defun accel (force mass currentAccel) "Calculate the acceleration of a body with mass == mass, and a current acceleration of currentAccel after force has been applied to it." (let ( (na `((x . ,(/ (cdr (assoc 'x force)) (float mass))) (y . ,(/ (cdr (assoc 'y force)) (float mass))))) ) (addVectors na currentAccel) )) ;; Set the value of the applied force. (setq f0 '((x . 5) (y . -5))) ;; Set the value of the initial acceleration. (setq ca '((x . 3) (y . 10))) ;; Set the body's mass. (setq m 10) ;; Set newAccel to be the resultant acceleration of the body with initial ;; acceleration == ca, mass == m, and force applied == f0. (setq newAccel (accel f0 m ca)) ;; Print out some results. (setq mess (format "
f0.x == %f N, f0.y == %f N\n
" (cdr (assoc 'x f0)) (cdr (assoc 'y f0)))) (setq mess (concat mess (format "
current acceleration x == %f m/s2, y == %f m/s2\n
" (cdr (assoc 'x ca)) (cdr (assoc 'y ca))))) (setq mess (concat mess (format "
Mass = %f kg\n
" m))) (message (format "%s
Resultant acceleration: x = %f y = %f\n
" mess (cdr (assoc 'x newAccel)) (cdr (assoc 'y newAccel))))
f0.x == 5.000000 N, f0.y == -5.000000 N
current acceleration x == 3.000000 m/s2, y == 10.000000 m/s2
Mass = 10.000000 kg
Resultant acceleration: x = 3.500000 y = 9.500000
1.1.3 Velocity
Velocity at some period Δ t after the present is given by:
\[ v(t + \Delta t) = v_{0} + \int_{t}^{t + \Delta t}a(t) dt \]
If we use the formula F = ma, then \(a = \frac{F}{m}\). Also, as we're sampling time periods, we can assume that F is constant over the period from t \(\rightarrow\) Δ t, and so we get:
\[ v(t + \Delta t) = v_{0} + \int_{t}^{t + \Delta t}\frac{F}{m} dt \]
\[ = v_{0} + \frac{F * \Delta t}{m} = v_{0} + a \times \Delta t \]
As discussed above, we're calculating the new acceleration of an element based on a force applied to the element and initial conditions of the element at a time t. The question is whether to calculate the new velocity instantly, in which case we're setting the new velocity for "now" as the velocity we'd achieve at Δ t, or to calculate the new velocity based on the current values of acceleration and current velocity at the end of the time period Δ t.
I'm choosing the second alternative. This means that before we begin our calculation of a new acceleration due to an applied force, we need to calculate the velocity.
So, assuming we've set a new acceleration at time t, then we can calculate the new velocity at time t + Δ t as follows:
(defun mulVector (vec scal) "Multiply vector vec by scalar scal." `((x . ,(* scal (cdr (assoc 'x vec)))) (y . ,(* scal (cdr (assoc 'y vec)))))) (defun velocity (v0 delta_t a) "Calculate the velocity after delta_t of an object with initial velocity v0 experiencing an acceleration of a." (addVectors v0 (mulVector a delta_t))) ;; Set an initial value for the velocity. (setq v0 '((x . 5) (y . -5))) ;; Set a time delta. (setq delta_t (/ (float 1) (float 10))) ;; Calculate the velocity of a body with initial velocity v0, experiencing an ;; acceleration of newAccel, after time delta_t. (velocity v0 delta_t newAccel)
1.1.4 Displacement / position
Each element will have an initial position. This will be some place in a container, possibly arbitrary, or perhaps ordered within some other set of elements.
The position of an element at time = t + Δ t, will be the position of the element at time t, + the velocity at time t multiplied by Δ t. So:
\[p(t + \Delta t) = p(t) + v(t) \times \Delta t \]
1.2 Sums of forces
Suppose we have a system containing 10 particles. For each particle we need to answer the following questions:
- What is the force exerted on this particle by all the other particles?
- What is the force exterted on every other particle by this particle?
Answering the second question actually answers the first, as the force that particle a exerts on particle b is exactly the same as the force that particle b exerts on particle a.
Suppose that the force exerted by this particle on it's neighbouring particles is just the force of gravity. Then all we need to know is the distance between this particle and the next to know the force that is being exerted on the next particle by this one, and to also know the force exerted on this particle by the next particle.
1.2.1 Algorithm 1
So, a simple algorithm to find all the forces exerted on all the particles would be:
- Begin with all particles in a list called particles:
- Pop a particle from the particles list and call it current
- For each particle p in the particle list, work out the force between current and p.
- Add that force to total force in current
- Add the force to total force in p - in the opposite direction,
- if there are more particles goto 3
- place current into a list called processed, and goto 2.
At the end of this algorithm, each particle should have a calculated total force applied to them. At this point it is possible to use that resultant force to calculate the new acceleration, velocity and position.
1.2.2 Algorithm 2
If we're simulating gravity or electrostatic charge in our system, then the force applied between A and B will be based solely on the distance between the two particles, and the charge or mass of A and B.
NOT SURE!
1.3 Containers and atoms
Elements are either atoms, or containers for other elements.
Atoms:
- have a mass,
- have a shape,
- have a position,
- have a velocity,
- have an acceleration,
- have an applied force.
The mass of an atom is considered to all be situated at it's (x, y) position.
A container:
- has a mass that is the sum of all the masses of it's contained elements,
- has a position - maybe the centre of mass,
- has a velocity,
- has an acceleration,
- has an applied force
Containers also can apply forces to the elements they contain, so that contained elements are constrained to be inside the container. The forces within a container should be fields, emanating from the container's boundaries.
2 UML
2.1 Composite layout object UML
Use the composite design pattern with an abstract base class lComponent, with subclasses lAtom and lContainer.
2.2 Abstract shape class
lAtom objects contain a abstract Shape class. The details of the GraphicalObject implementation and operation are dependent on the graphics techniques being used.
Define an abstract Shape class, and a concrete svg subclass.
3 Alternative approach - think about later.
Model the layout problem as a minimization problem, where the task is to minimize the resultant force on each particle.
Use gradient descent to find a θ vector that when mulitplied by polynomial factors generated from the x and y position, produces an x and y coordinate that mimimises the resultant force on the particle.
For particles layed out over a single dimension, perhaps with their x component constant, you'd only need the linear factors y and possibly x in their feature set. For 2-dimensional layouts, you'd need higher order polynomial terms, and combinations of terms.

How to motivate your teenager: coming from a teenage boy
First of all, I'd like to point out that I'm 17 currently and struggle to find motivation myself. I'm just here to give you, the parent, suggestions as to why your teen is not driven to do anything, as well as tell you some things that you may not want to hear.
1. Your teenager is not the problem.
I know that I'm making a huge generalization hear, but let me explain further. I can already tell by what you typed into the searchbar that you have the wrong perspective.  The motivation has to come from them, as you may have had to learn the hard way. Breaking this mindset is very crucial to facilitate the drive and motivation that your teen should have. Simply put, making your child do things that he/she/they do not want to do, and giving them responsibilities they are not willing to take will not help. It seems as though the root of this issue stems from their mental health. They first have to have their other needs met.As you can see from this heirarchy of needs, finding creativity and drive is at the top. One of the most sigificant things on this chart that I'd like you to note is directly under the highest need. Ego.
If you are not giving your child respect, and the choice to take responsibility for things by themself, there is no chance that they will have any motivation to do anything. To understand where I'm coming from, my Mother likes doing everything for me, and my Father really wants me to figure things out for myself and often makes me take up responsibilities that I don't care for. Optimally, your parenting should sit right in the middle of these two. You should allow your child to figure things out for themselves, but at the same time they need space and time to do their own thing.
 If you baby them, they won't learn anything, and you'll be left with someone who has no skills of their own. Find the middle ground.
2. Taking away priveleges is not a solution
There are countless studies showing that rewarding good behaviour is infinitely more effective than punishing bad behaviour. If you already allow your child to drink alcohol before the legal drinking age, play on their phone into ungodly hours of the night, and not show you the respect that you think you deserve, it's already too late. You cannot take away these things unless you're willing to lose all the respect you had from your teen. Just do not give them any more priveleges unless they earn it. Instead, You can reward the good. You should let your child know that you appreciate them if they do something notable, like washing the dishes themselves, or even showing you how to do something on your computer when you ask. The truth is, your teen probably wants to respect you, but you may be making that difficult for them to do. Going back to my previous point, your child needs to have everything sorted in the heirarchy of needs before they actually feel motivated to do things on their own. This means showing your teen respect, appreciation, and give them a sense of connection. They want to feel included, so make that easy for them to acquire.Something I should point out is that you can lead a horse to water, but you cannot make them drink it. If they have everything they need it may still take time for them to get motivation, and you can't force that on them. When your child displays that they feel appreciated and respected (whether through being in a better mood or taking up more responsibilities willfully), you know that you're doing the best job possible. This is all that you should be aiming for as a parent.
3. There needs to be some sort of order in the house
Listen, I don't know what kind of situation you're in. And I'm just a kid myself, why should my words have any bearing on your life anyway? But I can tell you right now: If you and your significant other yell at eachother and have a sporadic schedule, your teen will not react well to this. There needs to be something that they can expect every day, Whether that be dinner at the same time or even just a quiet afternoon to come home to, your teen needs to feel like they have some sort of expectation that they can expect a safe, unchanging(just not sporadic) environment that awaits them.If you already have this sort of environment, you can now focus on what your child actually wants out of life. Being in a pandemic and whatnot, right now is the perfect time to get involved with what your child is interested in, and how you can support them. I cannot stress how crucial it is for you to actually care about what your child needs.

Man, 70s, dies after car entered the sea in Galway
by By Pat FlynnAdditional reporting by Digital Desk
A man in his late 70s has died after the car he was driving went into the sea in Galway.
A multi-agency search and rescue operation was mounted at around 8pm last night at The Quay area of Kinvara.
The man who was the sole occupant of the car was brought to University Hospital Galway in a critical condition but later passed away.
The alarm was raised at around 8.10pm when, it is understood, people raised alarm at a local pub.
It is not clear whether they had seen the car in the water or actually witnessed it entering the sea.
The Irish Coast Guard mounted a major search and rescue operation and alerted a number of agencies.
Units of the fire brigade from Gort and Galway City, several National Ambulance Service resources and Gardaí responded to the incident while the Galway RNLI lifeboat was launched and dispatched to the area.
The Doolin unit of the Irish Coast Guard travelled to the scene by road with one of their rescue boats in tow while the Shannon based Irish Coast Guard helicopter, Rescue 115, was also tasked to assist.

In the meantime, it’s understood a number of locals had entered the water in an effort to reach the car.
Gardaí are appealing for anyone who was in the area at the time to come forward.
According to one man: "They were trying to get someone out but they couldn’t.
I think one of them was a diver because he knew what he was doing. The fire brigade and other emergency services started to arrive then.
Fire service personnel, trained in water rescue, also entered the water.
According to onlookers a local trawler was used to haul the car closer to the pier.
The man was recovered from the car at around 9pm and efforts quickly began to resuscitate him on the quayside.
A truck with a crane was sourced and the car was recovered from the water at around 9.15pm.
Gardaí are appealing for anyone with information, particularly any motorists who may have been in The Quay area Kinvara between 7.45am-8.15am who may have dash cam footage to come forward.
Anyone with information is asked to contact Gardaí in Galway on 091 538000 or the Garda Confidential Line on 1800 666 111.

Domain Driven Design (VI) + Industry Roundtable
Guest Author: Eric Evans
Notes by John Brewer and Jeff Miller
(some discussion of John Corbett's picture discussed on the list representing
evolution of a software system and easy/hard features within reach)
(lengthy roundtable discussion, omitted, of interesting new trends in
software, eventually rolling around to outsourcing)
Russ: It seems like a lot of jobs that are still high-skill are apt to
be commoditized in the next year or two. A lot of the web design tasks,
for example. There are easy-to-use tools to put together a site, even
with a shopping cart.
Eric: It seems like a lot of companies try to ship the wrong things offshore.
The domain business logic, which is actually one of the worst parts.
??: So they're thinking it's up front design, they'll just ship off the
spec.
Eric: But it doesn't work.
John: For big companies, they have a branch over there, not quite like
outsourcing.
??: A new thing, and widely perceived to be successful so far. Not so
many horror stories at this point.
Eric: Programming as unskilled labor? It's certainly some of it is more
semi-skilled than it used to be. Perhaps building a web page is rather
less technical than it was. So that's one thing. Partitioning jobs that
are less technical from ones that are more so. But it seems to me that
the domain layer is the last thing that will actually be automated. Then
there's the process. You can imagine an offshore shop full of smart people
using XP, and they would still be less in price. It's a little scary to
me, but in practice, I've never seen a big company get a really effective
process going locally, so...
Charlie: Savings of 20-35% seems to be what they're actually realizing.
Wages are going up in India, it's harder to manage a remote project.
John B: And there are things which end up in the wrong part of the balance
sheet, or opportunity costs that aren't measurable in a direct way. I
think this year we will hear many more offshore horror stories. It might
take two or three years before things really come crashing down, before
things finally come to account.
Mike: My company is partnering with a couple of established offshore
companies, and they're doing fairly well with it. They have a heavyweight
process, and it moves a little slow at the requirements phase, but the
code comes back in reasonable shape.
Eric: Yes, if you can write a spec and be happy getting back something
that meets the spec. But it doesn't necessarily make the next step easier.
There's no incentive in the structure to make to code supple, easy to
work with.
Russ: Not so much motivation, as just the way it works under this process.
Eric: But even without a breakthrough, the crafting of the pieces of
software.
Tracy: And the lack of access to interaction with customers, quick feedback.
The suppleness goes into the right place. People in a traditional waterfall
are hard to get to make changes. And unless there's someone right there
local, you don't get the little "aha!" insights, "Oh, that's
what you mean by a cargo!". Some local person who understands the
domain will make a little remark which will clarify issues for you, and
you'll have an insight that makes things much better.
John B: From "This Discipline of Market Leaders", you compete
with offshore people by choosing customer intimacy. Ex: FedEx: "innovation".
UPS: "operational excellence", Airborne Express, "customer
intimacy", they become part of your shipping division. They'll host
your company's warehouse in their shipping hub. We can't do operational
excellence, so we need to focus on innovation and customer intimacy. We
should take advantage of that, in the way that agile processes do.
Dave Smith: When I was managing a project, sometimes the customers are
distributed. In my case, it was financial companies around the Pacific
Rim.
Charlie: And you can use offshoring effectively for routine development
that's well understood.
Tim: When do you outsource? If it's well understood, get the requirements
exactly right and send it out to get typed up into code. But getting the
requirements exactly right *is* the central problem in software. Sending
the work outside the company is more apt to make things worse.
???: The better companies will provide a local representative to gather
requirements from the customer directly, and clarify anything that needs
more direct contact.
Dave Smith: Infosys, for example, has requirements teams local to the
customer. But wage inflation...there's high turnover in India, people
get hired away.
Eric: I think we should be glad that there are good opportunities there
now. A billion people pulling themselves out of poverty.
John B: A country of a billion plus people ought to have 3x as many genius
programmers. I think we should be very grateful, as programmers drawing
high salaries, that the regimes in these countries have held things back
up till now.
Darlene:
John B: Stories about mistreatment of knowledge workers.
Eric: I've heard of more problems here, like the H1B workers.
John B: I have another topic...the social networking software, LinkedIn
for example. It's a way of extending one's contacts. You can only initiate
requests directly through the set of contacts, and each contact has to
forward your request along.
(some discussion of automating programming...what level to write the
specs at... perhaps Java is a sufficiently formal language... but you'd
want a layered architecture with a good domain layer...so)
Eric: That's a good lead-in to the part of the book, Chapter 10 (Supple
Design). I favor a declarative style of design (p. 273). But there's a
problem with that mindset, you can get the wrong focus, which will lose
the details that will lose the agility of the process. I'm all for raising
the level of abstraction, but there's a problem with that particular direction
of abstraction, trying to make UML an executable specification.
Russ: When I first talked with Don Roberts, I couldn't see where some
of his points were coming from. You can't get all of the details right
up front, all of the bits of the landscape that give you the most appropriate
design.
Eric: ...building a language for my application. I used to think about
putting components together. But now I think about building up a language.
The fine-grained, well-crafted base level supports the next level of abstraction.
A layered language more than a layered architecture.
John: Some design methodologies inadvertently sabotage opportunities
for synergy, interplay between levels.
Russ: It felt like we used to design top-down, now it feels more like
inside-out. Starting somewhere in the middle of the system, and incrementally
fleshing it out as we go.
Jeff: That reminds me of one of the OOPSLA keynotes, that often the most
salient categories are those in the middle of an abstraction hierarchy,
rather than the most general or most specific categories.
Eric: I think this chapter is really important, but I'm not sure how
it comes across.
John B: It's sort of subtle, but it is self-reinforcing as it goes along.
Eric: And I pull from earlier stuff. The distinction between entities
and values becomes more important as you put side-effect-free functions
onto a value, etc.
Mike: I got one of those enterprise e-zines today, "go here and
look at the latest enterprise governance releases." What I read today
was the antithesis of it: "standard, standard, standard" rather
than a set of flexible guidelines to produce supple software.
Russ: Standards are motivated by fear.
Dave: But agile processes can have that motivation as well, once you
understand them. Fearing getting stuck in wasteful, painful activity.
John B: I prefer "winning" vs. "not losing". Agile
processes play to win, while standards-based processes play to not lose.
When a doctor says, "we did everything we could." And it's often
about big companies vs. small companies. Big companies have a lot to lose,
and so they play not to lose. Startups have to play to win, because playing
not to lose will just delay the point at which they lose.
Tim: How is one, as a manager, to see through the stories and choose
the right process?
Eric: I think that Supple Design is where the connection between design
and agile processes shows up the most. How to design things so that we
can change them when we need to.
Russ: Managers want to hear things in different ways. Some are more receptive
to the "Lean Software Development"
Charlie: Kent Beck's approach is to show something useful delivered every
iteration.
John B: I'd say that you should study persuasion, more than agile methods
or software development.
Eric: But frequent delivery can cause some distortions of the supple
design process from the pressure to deliver more each iteration. Ward
Cunningham recently was talking about "making the software softer."
Let's say you want to add a feature that doesn't look like it's going
to fit very well. You can add the feature in two different ways -- to
stick it on the side of the old system. Or you can rework the old system
until there is a place to put the new feature, and drop it in. His point
is that most people will do it the first way. They don't believe that
reworking the old system has value. But if you do it the second way, the
system ends up very easy to understand.
Tracy: "Hanging a bag on the side". You have to understand
the system, and then separately understand each bags.
And the mantra you hear is "but it works!" And until you've
gotten there, to where it encumbers you, you don't really see it.
Eric: Or when you've gotten to a really supple, unencumbered place. If
you deliver every three weeks.
Jeff: Version 1.0 of a product often has features but little design.
And then it comes time to start working on 2.0...
Eric: I think the payoff for supple design comes within weeks. It gives
you a better version 1.0, and makes a huge advantage in version 2.0
Russ: I've seen a problem with people reaching for a supple OO design
and dig a deeper hole with OO than they could have with a procedural language.
Eric: Even advanced designers can be too perfect, too abstract in their
design.
Tim: (describes a situation where success was redefined as the very limited
success that was actually achieved). We have a deployed product with a
lot of revenue in the field, but it costs so much in the support end that
it isn't a big win.
John B: A functional organization understands the cost of each tech support
call. So you make design decisions based on that if it's a significant
force.
Eric: At the place I've been working lately, they work hard to be compatible
with all the ancient versions of the web browsers. Who knows what happens,
if you make a few people unhappy. It changes the perception that it's
a site that is very easy and always works for everyone.
(some discussion of ease of use, supportable software, use of facilities
that only some people will be able to use or choose to enable: [Javascript,
ActiveX])
Eric: And sufficiently unpleasant things to work on will drive people
away. Supple Design makes things not only easier to work with, but more
pleasant.
Darlene: And easier to understand.
John B: Let me mention a phrase Ward Cunningham uses, "Design Debt".
He was working with financial services companies who understand the appropriate
use of debt. But you're talking about design surplus here, starting to
earn interest on the quality of your design.
Eric: I prefer supple design as a way to describe it, to describe where
you're at when you're free of design debt.
Russ: So at Eric's suggestion, perhaps we can pick up Chapter 13, which
is pretty short. "Refactoring Toward Deeper Insight".
Eric: It tries to tie together the whole of Part 3, since there are several
chapters there. It says similar things, but shifts the angle.
John B: This reminds me of Ward Cunningham's phrase about "waiting
for insight". You don't *have* to wait, but then you don't get the
insight.
Eric: But sometimes you have to go looking for it.
Charlie: Insight usually comes from hard work.
Eric: So you don't actually go looking for a breakthrough, but you keep
refining your knowledge and then you can be in a place where you can get
insights.
Russ: So, earlier you say, "you can't plan on a deep model."
But it seems you talk about a set of practices which give you opportunities
to break through to deeper insight into the model. Making your own luck.
Eric: You can still get a workable supple design.
Bob: Jazz improvisation. You still practice, you listen to other players,
learn new motifs, polish your scales, and then you're more ready when
the opportunity for an improvisational leak happens.
John B: For me, it often happens when something in the code bugs me.
And I reflect on it and I can make a breakthrough to a better design.
David V: When a system is in deployment, and you discover something where
you want to make a change, you may need to get management's agreement
to accept a risk. So right now we're looking at a "patch" release.
If you just fix the bug, versus using the opportunity to clear up a design
issue by making larger changes.
John B: Politically there are things you don't want to do in a small-point
release. Version 3.00 vs. Version 3.01, you wouldn't expect much of a
change in features or in how the system does its job. But if you're going
from version 1 and you have a big insight, then you may have to work that
out in the version 2 branch of the source, where you know that there will
be bigger changes and a full quality assurance cycle, and all the participants
will expect the larger changes.
Wayne: These breakthroughs are crucial for making a deep model. The little
stuff is important, but not the major part of the progress.
Eric: The little stuff is necessary to make the breakthroughs possible,
and is worth doing in its own right. I compared it to punctuated equilibrium
in evolution. (Which is itself a sudden insight which changed the evolutionary
model).
David V: It's all self-similar.
Charlie: The punctuated part was part of Darwin's theory that was lost.
Stephen Jay Gould discusses how the gradualism was a cultural accretion,
and in some ways punctuated equilibrium.
Eric: Right before a breakthrough, things don't feel good, and sometimes
right after as well. "There is a gaping hole in the model.... the
old model looks poor." (reading from page 326) So there is much work
to do, you look at the system and see how inadequate it is based on your
new understanding. And if people can see things from a different point
of view -- that they've learned something, that this is an advance. When
your model starts to look bad, you know you've learned something important.
Jeff: So this is a disillusionment with your original Hello Kitty picture
of the world.
Eric: Which shows you've learned something and can now make things better.
If people were more prepared to deal with the consequences of the breakthroughs
in knowledge, of feeling bad at that point, then they can work much more
effectively.
 -- mostly you feel pain and
loss.
Eric: You're attached to it.
Charlie: And you were proud of it.
Eric: Emotionally invested.
Mark?: People get identified with the design, especially if they participated
in creating it.
Eric: I've been in that situation, where I wasn't the one to see the
breakthrough. It isn't as satisfying as when you can see the change that's
needed. It's an essential part of our craft to detach, to let things go
when they aren't right any more.
Charlie: And six weeks ago you were really proud of it.
Eric: And perhaps it was the breakthrough from the previous version.
Mark: I'm often earliest to let go of my own code if there is something
better. Sometimes it's the other people on the team who don't want to
let go.
Eric: There's the notion of occupational temperaments. A perception that
software developers like to work alone. XP has changed some of that by
emphasizing a team focus, a social activity. But here's a different level
yet, of being detached from your own creation.
John C: And good diplomacy skills.
Eric: Yes, when you see a flaw in someone else's design. But it's not
one I think people are looking for when they're hiring, yet.
Carol: Why do people think there has to be one superior design. In architecture,
if you can give a client several designs, that's great, that you can see
different ways to do it.
Eric: The reason you can get away with a single model for your analysis
and design is that the model space is large, that you can explore it until
you find one that works for you in both ways. But I don't know why we
limit things.
Charlie: Architectural customers are better, more insightful about buildings
and needs than typical software customers.
Eric: We should remember that the original patterns movement was started
by Christopher Alexander, who was an architect dissatisfied with the building
architecture that he saw around him.
Tracy: Building design is more limited scope.
Russ: You can have discussions with the client about architectural issues,
alternatives in technology.
Carol: In architecture, earlier in the business, all the design documents
were manually drafted. After the advent of CAD, we ended up with the same
cost and time to deliver a design, but it was more detailed, more fully
developed. And the difference was in the cost of making changes. Moving
a wall was very painful if you had to manually redraw a lot of plans.
In software, we may not yet have the appropriate tools.
Eric: Better tools would be good, but again I resist that architecture
metaphor. I think these metaphors are throwing us off. [...]
Writing this book was much like software development. The experience of
inside out, top-down as well as bottom-up. Expressing some points you
want to make, and at the same time how to present it, how to organize
it. Crystallizing and refining concepts as you go along. You work, polish
things, then you finally understand it and you have to let your work go
and rewrite it to what it needs to be. I recall a quote from Hemingway,
if there was a really polished, really beautiful page or paragraph, the
best thing he could do for the rest of the book was to throw it away.
We get stuck endlessly in choosing the right metaphor -- architecture,
manufacturing. And as you point out (to John B), we don't even do them
well.
Dave Smith: Architectural designs, at the time they are sold to the customer,
are far more visions than designs. A construction company would be very
angry with trying to actually implement the design.
John B: There are two outcomes in software development, "I'm a great
architect" or "You are lousy programmmers".
