"The docs by themselves simply will not teach you how Angular works."

Well said, and I agree, but I wonder why this is? There's some cred to be gained by making and using something so impenetrable that only a select handful of people 'just know' how something works, and everyone aspires to be like them?

I've found plenty of people/blogs/sites telling me I'm doing angular 'wrong' (and not just angular - other frameworks/libraries) but precious few people can demonstrate a 'right' way to do things which actually accommodates real world use cases. On top of that, what was canonical at one point is later made obsolete via a single patch/push, but the blogosphere/google never quite catch up.

Less an angular-specific rant, more an observation as to how more projects seem to be heading. As I become one of the 'older' generation, I'm seeing more younger devs (under 25, less than 3 years of professional experience) embracing this code lifestyle, and seem to think it's great, and old fogeys like me just 'can't keep up'. Maybe I can't, but perhaps if you'd document your stuff a bit more, we could just use the library instead of having to read every single line of code, commit, watch for patches, finagle and beg to get pull requests taken and used, and pray that the next point release doesn't break everything. Obviously not all projects are like this, but it seems there's a growing trend among younger projects to work this way. Or maybe I'm just getting old...

They say that great athletes make bad coaches. Why? Because they can't explain what came instinctively.

Similarly, the wrong person to write documentation is the creator of a system. He or she will not know what leaps of understanding are being made throughout the text. That's why big IT companies have historically hired technical writers, which is a profession in its own right.

Those general observations aside, I believe that for some of the Angular team English is a second language.

But otherwise, in the case of the Angular docs, there is a simple lack of attention to detail. Poor fit and finish. It's pretty clear that a lot of the documentation is the first draft.

In the comments you can always find someone complaining and someone else saying "fork it on github". If you actually go and look at github, there are hundreds of unanswered pull requests. So clearly that isn't working either.

"They say that great athletes make bad coaches. Why? Because they can't explain what came instinctively."

Thank you for finally explaining to me why mathematicians are such famously bad teachers of math. They just start scribbling symbols without explaining what they mean because of course you know what they mean...

[jacques_chester]

I first heard it from one of the world's most experienced weightlifting coaches, Lyn Jones. It explained a lot to me too.

The corollary is that people who love something, but can't do it easily, tend to be good coaches. Because they've had to really make an effort and have diligently sought out ways to improve themselves.

Put another way: "those who can't do, teach" isn't an insult to teachers. It's praise.

Great quote from George Leonard's Mastery:

"In his book Zen Mind, Beginner’s Mind, Zen master Shunryu Suzuki approaches the question of fast and slow learners in terms of horses. “In our scriptures, it is said that there are four kinds of horses: excellent ones, good ones, poor ones, and bad ones. The best horse will run slow and fast, right and left, at the driver’s will, before it sees the shadow of the whip; the second will run as well as the first one, just before the whip reaches its skin; the third one will run when it feels pain on its body; the fourth will run after the pain penetrates to the marrow of its bones. You can imagine how difficult it is for the fourth one to learn to run.

When we hear this story, almost all of us want to be the best horse. If it is impossible to be the best one, we want to be the second best.” But this is a mistake, Master Suzuki says. When you learn too easily, you’re tempted not to work hard, not to penetrate to the marrow of a practice.

“If you study calligraphy, you will find that those who are not so clever usually become the best calligraphers. Those who are very clever with their hands often encounter great difficulty after they have reached a certain stage. This is also true in art, and in life.” The best horse, according to Suzuki, may be the worst horse. And the worst horse can be the best, for if it perseveres, it will have learned whatever it is practicing all the way to the marrow of its bones."

Maybe that old saying should be rephrased to "those who can't instinctively do, teach".

[api]

That's actually incredibly optimistic... it means if someone has to struggle really really hard to get something, they're quite possibly better to teach it to others. The struggle itself imparts a unique skill that those that get it more "naturally" might not have.

[stretchwithme]

Those who understand how to do should teach.

Spot on.

"In the comments you can always find someone complaining and someone else saying "fork it on github". If you actually go and look at github, there are hundreds of unanswered pull requests. So clearly that isn't working either."

Agreed.

I would disagree that the person/team writing something isn't fit to document it. Yes, sometimes they're not the best choice, but often they're the only person, and there's no 'choice' at all.

[pkozlowski_os]

Let's be precise - at the moment there are exactly 68 open pull requests, _one_ of them being about documentation: https://github.com/angular/angular.js/pulls

There is a huge difference in the open source world between ranting and actually doing something about your pain-points.

[paulwithap]

One open pull request, but every single page of the documentation is filled with comments from confused people asking for better docs. Fortunately, there's also sometimes a comment giving a proper explanation of that piece of the API.

[chroto24]

Sounds like the PHP docs

[jacques_chester]

There were more when I first checked.

Besides, it's hard for me to fix that I couldn't understand the docs when starting from the position of ... not understanding the docs.

[marincounty]

1. Yea, I agree. 2. This industry(Comuter Science) is not taught very well. 3. I cringe when I see those 500 page "manuals".

[ams6110]

What these "younger devs" don't realize is that in most cases they are simply reinventing stuff that has existed for years. Even today, the best JS MVC frameworks only just provide the capabilities to build UIs that (for example) were trivial in PowerBuilder 20 years ago.

The fact that it's considered "gee whiz" that you can enter a value into a form field and have that value automatically validated and bound to an attribute in a "model" shows how little we have really advanced.

Web UIs offer a lot in the way of visual styling and easy distribution... but the actual building of apps hasn't really advanced much.

[jacques_chester]

I sometimes wonder what the world would look like if somehow it was all hypercards or DCOM or OpenDoc or NeWS or just about anything other than a simple document format painfully hammered into the shape of an applications platform.

[jfb]

It's fun to run the counterfactuals, but ultimately, we go to war with the lousy technology stack we have, not the mediocre one we want. I'm just overjoyed that, thanks to Android and iOS, people are writing native applications again.

[SimHacker]

There are known IKnowns: there are APIs we know that we know. There are known IUnknowns: that is to say, there are APIs that we now know we don't know. But there are also unknown IUnknowns: there are APIs we do not know we don't know.

[timmy-turner]

Just reinventing the wheel to not having to use Powerbuiler makes a lot of sense to me. Even if it takes 20 years. Even if it only covers the trivial features. 5 years ago, I used to work on two huge Powerbuilder projects. I don't remember having real models or support for them in Powerbuilder and these projects. Everything was just datawindows, embedded SQL and stored procedures. I'm really glad that I'm now working on a web application at a different company.

[kawera]

What these "younger devs" don't realize is that in most cases they are simply reinventing stuff that has existed for years.

And this is also true for so many aspects of the modern "stack" - remember "time sharing"?

[rdtsc]

"Those that don't learn from history are bound to repeat it"

This includes both repeating the mistakes and design issues, but also getting excited about the "invention".

[dirtyaura]

I wouldn't say that Angular is reinventing the wheel. Elegant and efficient two-way data binding is a non-trivial problem, and I haven't seen it implemented well (or at all!) in any UI framework that I have worked with in the last 15 years.

[mickeyp]

Delphi had amazing data binding. You literally dropped two non-visual components on your form; plonked down data-aware components; and then pointed it at any number of databases via ADO, DAO, ODBC or BDE and you were flying.

Unrivalled flexibility and power and you could do knock together a CRUD app in a couple of hours.

Add to that the incredible flexibility afforded by 3rd party components like DevExpress and you had grids and other tabular components that even today any amount of HTML5, JS and CSS and backend programming could only dream of achieving.

And we did this in the 90s.

[warfangle]

How was it at near-platform-universality and secure HTTP transmission?

[jacques_chester]

Windows was the near-universal platform and fairly sophisticated networking ability was inbuilt.

[coldtea]

You mean getting something else (that's orthogonal) in exchange, justifies a regression to pre-90's in other areas?

[mickeyp]

Plus it was trivial to make n-tier architectures. Tying it to the web was quite easy too, and there were components out there that made data interchange via HTTP trivial - like SOAP.

[icedchai]

It's so true... It's sad we've wasted so much effort putting square pegs in round holes.

[steveklabnik]

Writing documentation is really hard.

It's also hard to get people to contribute to documentation. I had a conversation with someone recently that was frustrated about the Rails documentation: "Here's my blog post about how to do X. Apparently that's what Rails people do rather than write docs." When I asked why they didn't contribute to the docs rather than make Yet Another Blog Post that feeds into the exact problem they were talking about, it just hadn't actually occurred to them. Getting started contributing to a new project is difficult, posting something to your blog is easy.

Most people don't find writing docs to be fun, and Open Source is largely driven around doing what's fun.

It's hard to see the flaws in something you're close to. The people who are closest to a project forget how hard it is to come in from nothing; I had a conversation recently about Hackety Hack where someone was upset it didn't have the ability to make folders and multi-file projects, and when I tried to explain to them that the beginners (children and adults) that I teach actually struggle with things like file management, they were shocked. We all forget just how much we know, because it's easy to us!

Furthermore, there's an incentive for people to write blog posts over contribute to official docs, since then people will link to their blog, with all the benefit that comes along with.

I am not informed on the state of Angular's documentation, and I think Rails has pretty decent docs these days, but there's lots of reasons why docs are often poor in open source projects.

[rdtsc]

> Writing documentation is really hard.

If that is the case then one should wonder about the project itself. If the idea and functionality cannot be easily expressed then one wonders whether that project is worth pursuing.

I stopped being interested in the project. I did look at the source and all the magic going on behind the scenes and didn't like what I saw. It reminds of those large frameworks management would buy for big enterprises and say "just use this, this will be really easy, we'll increase the productivity 100%!".

[sanderjd]

I realized something recently about docs-vs-blogs. An important difference between the two is that official documentation of a project is the place to say "this is how it is done", whereas blogs are a place to say "this is how I do it". If there isn't a consensus on how something should be done, but you think the way you do it is nice, it definitely makes sense to write about that in a blog post, but it only possibly makes sense to propose your way for official documentation.

I think it took all those blog posts to generate all the consensus necessary to make the "pretty decent" (I would say "very good") Rails docs possible.

[pixelcort]

An official blog can be, "This is how it is done, as of the time of posting."

However, then you end up with blog posts like, "here what's new in 3.5", without any documentation for users who never used 3.4 (or 3.3, 3.2...)

[Foxandxss]

You made a good point here. That point of view will prove to be useful to me :)

[regularfry]

My very first PR to the Emberjs project was an improved entry-level tutorial, just to work people past the pain points I'd experienced getting up and running following the then-current getting started guide (which were neither few, nor far between). The initial response? "This would be better as a blog post."

[mgkimsal]

WOW - that's crazy. Thanks for a recent real world example.

[Foxandxss]

I agree with you.

I don't feel I have the experience to write better angular docs. That could be a goal in a future for sure.

Even when I am going to write about things that could be used to improve the official docs, one of my main goals is to answer via blog the questions I see everyday: "Why this doesn't work?", "My directive is not doing what I need", "My service is not updating"...

I think that the documentation itself needs to be done from various angles, and this is one for me.

[pm]

Documentation is hard because those who are documenting assume too much about those who are learning. This concept applies as much to closed source projects as it does to open source projects. It's all a matter of being open to those who are learning, and incorporating what they don't understand.
