You’ll find this post in your `_posts` directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run `jekyll serve`, which launches a web server and auto-regenerates your site when a file is updated.
To add new posts, simply add a file in the `_posts` directory that follows the convention `YYYY-MM-DD-name-of-post.ext` and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.
Jekyll also offers powerful support for code snippets:
{% highlight ruby %}
def print_hi(name)
puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.
{% endhighlight %}
Check out the [Jekyll docs][jekyll-docs] for more info on how to get the most out of Jekyll. File all bugs/feature requests at [Jekyll’s GitHub repo][jekyll-gh]. If you have questions, you can ask them on [Jekyll Talk][jekyll-talk].

<div class="block">An interface for providing new partitions for a partitions iterator.
The new contents are produced as a normal arbitrary PartitionIterator or UnfilteredPartitionIterator (as appropriate)
The transforming iterator invokes this method when any current source is exhausted, then then inserts the
new contents as the new source.
If the new source is itself a product of any transformations, the two transforming iterators are merged
so that control flow always occurs at the outermost point</div>

title: Mais Pequenos Pedaços de Análises
answer: [3-9]
load: livros = {"O Arco-Íris da Gravidade" => :esplendido}
ok: Veja, o método length trabalha com strings, arrays e hashes
error:
---
Vá em frente, preencha a lista com análises. E, se você quiser ver toda a lista, apenas digite: __puts livros__
Denovo, as classificações são: :esplendido, :muito\_bom, :mediocre, :nao\_tao\_bom e :lixo
Essas classificações não são strings. Quando você coloca dois pontos a frente de uma simples palavra, você obtém um __symbol__ (símbolo).
Símbolos são mais baratos que strings (em termos de custo de memória). Se você usar uma palavra várias e várias vezes no seu programa,
troque por um símbolo. Ao invés de ter milhares de cópias desta palavra na memória, o computador irá armazenar o símbolo apenas __uma vez__.
Mais importante, um símbolo diz a você que isso não é apenas uma palavra, mas algo que tem significado para o seu programa.
Entre com mais duas análises de livros, use __livros.length__ para ver quantas análises já existem no hash:
livros["Até o Fim"] = :lixo
livros["Cores Vivas"] = :mediocre
puts livros
puts livros.length

# Flight
[](http://travis-ci.org/flightjs/flight)
[Flight](http://flightjs.github.io/) is a lightweight, component-based,
event-driven JavaScript framework that maps behavior to DOM nodes. It was
created at Twitter, and is used by the [twitter.com](https://twitter.com/) and
[TweetDeck](https://web.tweetdeck.com/) web applications.
* [Website](http://flightjs.github.io/)
* [API documentation](doc/README.md)
* [Flight example app](http://flightjs.github.io/example-app/)
* [Flight's Google Group](https://groups.google.com/forum/?fromgroups#!forum/twitter-flight)
* [Flight on Twitter](https://twitter.com/flight)
## Why Flight?
Flight is only ~5K minified and gzipped. It's built upon jQuery, and has
first-class support for AMD and [Bower](http://bower.io/).
Flight components are highly portable and easily testable. This is because a
Flight component (and its API) is entirely decoupled from other components.
Flight components communicate only by triggering and subscribing to events.
Flight also includes a simple and safe
[mixin](https://javascriptweblog.wordpress.com/2011/05/31/a-fresh-look-at-javascript-mixins/)
infrastructure, allowing components to be easily extended with minimal
boilerplate.
## Development tools
Flight has supporting projects that provide everything you need to setup,
write, and test your application.
* [Flight generator](https://github.com/flightjs/generator-flight/)
Recommended. One-step to setup everything you need to work with Flight.
* [Flight package generator](https://github.com/flightjs/generator-flight-package/)
Recommended. One-step to setup everything you need to write and test a
standalone Flight component.
* [Jasmine Flight](https://github.com/flightjs/jasmine-flight/)
Extensions for the Jasmine test framework.
* [Mocha Flight](https://github.com/flightjs/mocha-flight/)
Extensions for the Mocha test framework.
## Finding and writing standalone components
You can browse all the [Flight components](http://flight-components.jit.su)
available at this time. They can also be found by searching the Bower registry:
```
bower search flight
```
The easiest way to write a standalone Flight component is to use the [Flight
package generator](https://github.com/flightjs/generator-flight-package/):
```
yo flight-package foo
```
## Installation
If you prefer not to use the Flight generators, it's highly recommended that
you install Flight as an AMD package (including all the correct dependencies).
This is best done with [Bower](http://bower.io/), a package manager for the web.
```
npm install -g bower
bower install --save flight
```
You will have to reference Flight's installed dependencies –
[ES5-shim](https://github.com/kriskowal/es5-shim) and
[jQuery](http://jquery.com) – and use an AMD module loader like
[Require.js](http://requirejs.org/) or
[Loadrunner](https://github.com/danwrong/loadrunner).
```html
<script src="bower_components/es5-shim/es5-shim.js"></script>
<script src="bower_components/es5-shim/es5-sham.js"></script>
<script src="bower_components/jquery/jquery.js"></script>
<script data-main="main.js" src="bower_components/requirejs/require.js"></script>
...
```
## Standalone version
Alternatively, you can manually install the [standalone
version](http://flightjs.github.io/release/latest/flight.js) of Flight, also
available on [cdnjs](http://cdnjs.com/). It exposes all of its modules as
properties of a global variable, `flight`:
```html
...
<script src="flight.js"></script>
<script>
var MyComponent = flight.component(function() {
//...
});
</script>
```
N.B. You will also need to manually install the correct versions of Flight's
dependencies: ES5 Shim and jQuery.
## Example
A simple example of how to write and use a Flight component. Read the [API
documentation](doc) for a comprehensive overview.
```js
define(function (require) {
var defineComponent = require('flight/lib/component');
// define the component
return defineComponent(inbox);
function inbox() {
// define custom functions here
this.doSomething = function() {
//...
}
this.doSomethingElse = function() {
//...
}
// now initialize the component
this.after('initialize', function() {
this.on('click', doSomething);
this.on('mouseover', doSomethingElse);
});
}
});
```
```js
/* attach an inbox component to a node with id 'inbox' */
define(function (require) {
var Inbox = require('inbox');
Inbox.attachTo('#inbox', {
'nextPageSelector': '#nextPage',
'previousPageSelector': '#previousPage',
});
});
```
## Browser Support
Chrome, Firefox, Safari, Opera, IE 7+.

USAGE
model <class-name> [table-name]
DESCRIPTION
This command generates a model class with the specified class name.
PARAMETERS
* class-name: required, model class name. By default, the generated
model class file will be placed under the directory aliased as
'application.models'. To override this default, specify the class
name in terms of a path alias, e.g., 'application.somewhere.ClassName'.
If the model class belongs to a module, it should be specified
as 'ModuleID.models.ClassName'.
If the class name ends with '*', then a model class will be generated
for EVERY table in the database.
If the class name contains a regular expression deliminated by slashes,
then a model class will be generated for those tables whose name
matches the regular expression. If the regular expression contains
sub-patterns, the first sub-pattern will be used to generate the model
class name.
* table-name: optional, the associated database table name. If not given,
it is assumed to be the model class name.
Note, when the class name ends with '*', this parameter will be
ignored.
EXAMPLES
* Generates the Post model:
model Post
* Generates the Post model which is associated with table 'posts':
model Post posts
* Generates the Post model which should belong to module 'admin':
model admin.models.Post
* Generates a model class for every table in the current database:
model *
* Same as above, but the model class files should be generated
under 'protected/models2':
model application.models2.*
* Generates a model class for every table whose name is prefixed
with 'tbl_' in the current database. The model class will not
contain the table prefix.
model /^tbl_(.*)$/
* Same as above, but the model class files should be generated
under 'protected/models2':
model application.models2./^tbl_(.*)$/

* Checks if the given table is a "many to many" helper table.

title: What I want from a computer
---
A loose collection of (very IMHO) ideas what a computer system built for
productivity should be like, everything goes, but nothing too crazy.
### Operating System
The OS itself is reduced to a minimal hardware abstraction layer:
- input
- audio
- filesystem
- networking
- 3D rendering API
- (and probably one or two essential things I forgot)
The OS APIs are exposed as C headers, because C is the lingua franca that all
other languages can talk to. That doesn't mean that the OS itself
has to be written in C.
There's only a simple window composer which can compose rectangles rendered
through the 3D API.
There is no UI framework built into the OS, applications
select their own 3rd-party UI framework (may the best win). Having
no standard UI framework sounds messy, but it is already a reality for
cross-platform apps, which are usually written with Qt or Electron.
Above this basic hardware abstraction layer there's a fork in the road,
one side leads to the dark side, a 'walled garden consumption OS', the
other side to an 'open productivity & creativity OS'. It doesn't make
any sense trying to combine the two ideologies, it only ends in pain
and suffering for everyone, as Windows 8 has shown.
This is about the creativity/productivity fork:
### Software Installation
A 'friendly' command line package manager like brew, coupled with a very
simple configuration system which allows me to automate system setup (what
software to install, config files, etc...).
Basically the opposite of Windows's sloppy installation system or the
Mac's restrictive App Shop.
The idea is that I want the entire configuration of my machine in a setup script
under version control. Resetting the machine to a clean slate, or setting up
an entirely new machine should not require any manual work.
### Filesystem
Instead of a rigid directory hierarchy I want to add custom attributes to
files (tags and key/value pairs). Some sort of hierarchical tags could be
used to simulate traditional directory hierarchies. The 'filename' is also
just a tag. File management tools and command line shells have realtime
fuzzy-search by file attributes (much like the incremental fuzzy search in
modern text editors works), while at it, drop the whole 'desktop metaphor'
bullshit once and for all.
There are no silly icons (except maybe for apps), only the
*file content* and tags are important.
I'm not sure about an integrated version control system, on one hand
it might make sense, on the other hand there is no consensus what a
good VCS looks like. So better to let the user decide.
### User Interaction
I want 'friendly, explorable, text-driven' interaction. I want to
start typing anywhere, anytime, and the system or current app should offer me
options through fuzzy-search (of apps to start, files to work on,
commands to execute and so on).
I want to easily navigate previous actions (through an ever-present context-
sensitive history), and possible next actions (through the fuzzy matching).
Look at the fish shell and Sublime Text's command palette for examples
how this would work.
Being mainly text-driven doesn't mean there can't be typical mouse- or
touch-driven apps like 3D-modelling or 2D-drawing tools.
### Scriptable UI Apps
All UI apps worth their salt should also offer a language-agnostic scripting
interface for automation tasks, similar to what the Amiga started
with AREXX scripting.
### Conclusion
> Netscape will soon reduce Windows to a poorly debugged set of device drivers
>
> *(Marc Andreessen, 1995)*
That's exactly what *all* operating systems should be IMHO, except for the
'poorly debugged' part of course :D

/**
* {@link DocumentsWriterDeleteQueue} is a non-blocking linked pending deletes
* queue. In contrast to other queue implementation we only maintain the
* tail of the queue. A delete queue is always used in a context of a set of
* DWPTs and a global delete pool. Each of the DWPT and the global pool need to
* maintain their 'own' head of the queue (as a DeleteSlice instance per DWPT).
* The difference between the DWPT and the global pool is that the DWPT starts
* maintaining a head once it has added its first document since for its segments
* private deletes only the deletes after that document are relevant. The global
* pool instead starts maintaining the head once this instance is created by
* taking the sentinel instance as its initial head.
* <p>
* Since each {@link DeleteSlice} maintains its own head and the list is only
* single linked the garbage collector takes care of pruning the list for us.
* All nodes in the list that are still relevant should be either directly or
* indirectly referenced by one of the DWPT's private {@link DeleteSlice} or by
* the global {@link BufferedUpdates} slice.
* <p>
* Each DWPT as well as the global delete pool maintain their private
* DeleteSlice instance. In the DWPT case updating a slice is equivalent to
* atomically finishing the document. The slice update guarantees a "happens
* before" relationship to all other updates in the same indexing session. When a
* DWPT updates a document it:
*
* <ol>
* <li>consumes a document and finishes its processing</li>
* <li>updates its private {@link DeleteSlice} either by calling
* {@link #updateSlice(DeleteSlice)} or {@link #add(Term, DeleteSlice)} (if the
* document has a delTerm)</li>
* <li>applies all deletes in the slice to its private {@link BufferedUpdates}
* and resets it</li>
* <li>increments its internal document id</li>
* </ol>
*
* The DWPT also doesn't apply its current documents delete term until it has
* updated its delete slice which ensures the consistency of the update. If the
* update fails before the DeleteSlice could have been updated the deleteTerm
* will also not be added to its private deletes neither to the global deletes.
*

title: "**HOWTO:** Decode to Texture"
---
# **HOWTO:** Decode to Texture
Starboard declares the interfaces necessary to allow applications to query for
video frames from the media player, and have them returned as texture objects
(e.g. GLES textures). This is useful if the application would like to apply
a geometrical transformation to the rendered video, in order to support 360
spherical video playback for example. Additionally, if a Starboard platform
implementation does not support punch-through video playback, then
applications can choose to use decode-to-texture instead.
## API Overview
Decode-to-texture support involves multiple Starboard API functions spanning
both the [`starboard/player.h`](../player.h) and
[`starboard/decode_target.h`](../decode_target.h) Starboard interface header
files. Support for decode-to-texture began in version 4 of the Starboard
API.
In particular, the following function implementations require consideration
for decode-to-texture support:
From [`starboard/player.h`](../player.h),
* `SbPlayerCreate()`
* `SbPlayerGetPreferredOutputMode()`
* `SbPlayerGetCurrentFrame()`
From [`starboard/decode_target.h`](../decode_target.h),
* `SbDecodeTargetRelease()`
* `SbDecodeTargetGetInfo()`
Note that it is possible that you may not need to use the
`SbDecodeTargetGraphicsContextProvider` parameter of SbPlayerCreate(). More on
this later.
## Example Application Usage Pattern
We now describe an example, and typical, sequence of steps that an
application will take when it wishes to make use of decode-to-texture
support.
1. An application with the desire to make use of decode-to-texture will first
call `SbPlayerGetPreferredOutputMode()`, passing in
`kSbPlayerOutputModeDecodeToTexture` for its `creation_param->output_mode`
parameter. If the function doesn't return
`kSbPlayerOutputModeDecodeToTexture`, the application learns that
decode-to-texture is not supported by the platform and it will not continue
with a decode-to-texture flow.
2. If `SbPlayerGetPreferredOutputMode()` returns
`kSbPlayerOutputModeDecodeToTexture`, the application will call
`SbPlayerCreate()`, passing in `kSbPlayerOutputModeDecodeToTexture` for
the `creation_param->output_mode` parameter, and also providing a valid
`provider` parameter (more on this later). At this point, the Starboard
platform is expected to have created a player with the decode-to-texture
output mode.
3. Once the player is started and playback has begun, the application's
renderer thread (this may be a different thread than the one that called
`SbPlayerCreate()`) will repeatedly and frequently call
`SbPlayerGetCurrentFrame()`. Since this function will be called from the
application's renderer thread, it should be thread-safe. If the platform
uses a GLES renderer, it is guaranteed that this function will be called
with the GLES renderer context set as current. This function is expected
to return the video frame that is to be displayed at the time the function
is called as a `SbDecodeTarget` object. The `SbPlayerGetCurrentFrame()`
will be called at the renderer's frequency, i.e. the application render
loop's frame rate. If the application's frame rate is higher than the
video's frame rate, then the same video frame will sometimes be returned
in consecutive calls to `SbPlayerGetCurrentFrame()`. If the video's frame
rate is higher than the application's (this should be rare), then some
video frames will never be returned by calls to
`SbPlayerGetCurrentFrame()`; in other words, video frames will be
dropped.
4. Once the application has acquired a valid SbDecodeTarget object through a
call to `SbPlayerGetCurrentFrame()`, it will call
`SbDecodeTargetGetInfo()` on it to extract information about the opaque
`SbDecodeTarget` object. The `SbDecodeTargetGetInfo()` function fills
out a `SbDecodeTargetInfo` structure which contains information about the
decoded frame and, most importantly, a reference to a GLES texture ID on
GLES platforms, or a reference to a `SbBlitterSurface` object on
Starboard Blitter API platforms. The application can then use this
texture/surface handle to render the video frame as it wishes.
5. When the application is finished using the `SbDecodeTarget` that it has
acquired through the `SbPlayerGetCurrentFrame()` function, it will call
`SbDecodeTargetRelease()` on it. The Starboard platform implementation
should ensure that the `SbDecodeTarget` object returned by
`SbPlayerGetCurrentFrame()` remains valid until the corresponding call to
`SbDecodeTargetRelease()` is made. A call to `SbDecodeTargetRelease()`
will be made to match each call to `SbPlayerGetCurrentFrame()`.
## The `SbDecodeTargetGraphicsContextProvider` object
It is completely possible that a platform's Starboard implementation can
properly implement decode-to-texture support without dealing with the
`SbDecodeTargetGraphicsContextProvider` object (passed in to
`SbPlayerCreate()`). The `SbDecodeTargetGraphicsContextProvider` reference
gives platforms references to the graphics objects that will later be used to
render the decoded frames. For example, on Blitter API platforms, a reference
to the `SbBlitterDevice` object will be a mamber of
`SbDecodeTargetGraphicsContextProvider`. For EGL platforms, a `EGLDisplay` and
`EGLContext` will be available, but additionally a
`SbDecodeTargetGlesContextRunner` function pointer will be provided that will
allow you to run arbitrary code on the renderer thread with the `EGLContext`
held current. This may be useful if your `SbDecodeTarget` creation code will
required making GLES calls (e.g. `glGenTextures()`) in which a `EGLContext` must
be held current.
## Performance Considerations
The decode-to-texture Starboard API is specifically designed to allow
Starboard implementations to have the player decode directly to a texture,
so that the application can then reference and render with that texture
without at any point performing a pixel copy. The
decode-to-texture path can therefore be highly performant.
It is still recommended however that platforms support the punch-through
player mode if possible. When using the decode-to-texture player output
mode, the video may be rendered within the application's render loop, which
means that non-video-related time complexity in the application's render
loop can affect video playback's apparent frame rate, potentially resulting in
dropped frames. The platform can likely configure punch-through video to
refresh on its own loop, decoupling it from the application render loop.
## Implementation Strategies
### Working with "push" players
If your player implementation is setup with a "push" framework where
frames are pushed out as soon as they are decoded, then you will need
to cache those frames (along with their timestamps) so that they can be
passed on to the application when `SbPlayerGetCurrentFrame()` is called.
This same strategy applies if the player pushes frames only when they are meant
to be rendered.
