Part IV: Lighting with SceneKit💡
In the last few parts of the series, we’ve discussed how to setup an AR Session, detecting planes, and adding 3D objects to your session. To make your 3D content all better, we’ll work with lighting in this section.
Fill — How?
The 3D content, which are nothing but SCNNode
objects that we add to the session, have an array property — materials
that hold an array of SCNMaterial
objects. To be able to fill an object with a solid color, all there is to do is:
- Create a
SCNMaterial
object - Assign a color to its
diffuse
property - Add the created
SCNMaterial
object to thematerials
array of theSCNNode
And that’s all there is to it.
Code:
This piece of code should accomplish adding a fill to your node. Let’s look into how to add a light node to the scene.
Lighting with SceneKit
The primary premise around Augmenting Reality is that you add virtual objects to the real one, and the objects we add need to look and feel like they’re part of the actual space you’re interacting with. Lighting your objects right help you with this.
Lighting adds a layer of realism to your 3D objects. With SceneKit, this is accomplished by adding SCNLight
objects to your scene.
There are different types of SCNLight, that can be used based on the kind of lighting you want in your scene:
- Omni
- Ambient
- Directional
- Spot
- IES
- Probe
Using one or more lights in combination in your scene will give you all different kinds of interesting lighting.
To light a 3D object in the scene, very simply, we need two types lights in the scene:
- Spot (or) Directional Light
- Ambient
We add an Ambient light source to our scene because in real life, there are multiple light sources and light bounces of every surface lighting all sides of an object. We simulate this by adding an Ambient Light along with a Spot light or a Directional Light to light the object up.
Code
-
1. Creating a Spot Light
2. Creating an Ambient Light
3. Adding them to your scene
SCNLight
has a property called intensity
that signifies the luminous flux in lumens, or the total brightness of the light.
SCNView
has a boolean property called automaticallyUpdatesLighting
, which when true
adds an Omni lightsource to the scene pointing in the direction of the camera and sets its intensity to 1000
by default.
We can manipulate realism, or how realistic an object is by actively controlling the intensity property of our lights in the scene. To be able to do this, let’s turn the default lighting off:
sceneView.autoenablesDefaultLighting = false
The ARConfiguration
instance that we use to setup an ARSession
has a boolean property called lightEstimationEnabled
, which when true gives us a light estimate value of every ARFrame
that’s captured. This is very useful because we can leverage the lightEstimate
property to update our lights with the right intensity based on the environment.
Code
-
1. Enabling Light Estimation in the scene
2. Using light estimates to update lighting
Using Light Estimation this way helps with realism to a certain extent, and works most times if the user is engaged within the experience in a well-lit environment.
Advanced Lighting with SceneKit: PBR
We have seen how to use basic lighting to light up your 3D objects, and make it look realistic. We can now go one step further with a technique called Physically Based Rendering to texture our objects and make it convincing.
These are the different lighting models that we could use to light our objects up. We’ll look at how to use PBR to make a realistic looking objects.
Simply put, PBR lighting leverages the following material properties to compute lighting and texture on the object:
diffuse
: The diffuse property provides the base color of the material. Also known as albedo in some authoring tools.roughness
: This provides an approximation of the microscopic detail in a real-world surface.metalness
: This provides an approximation of how shiny the material is going to be.
More specifics on the lighting terms are described excellently here.
The process to apply materials to SCNNode is similar to how we applied a fill in our object earlier, except for the PBR lighting we will be providing the relevant properties we discussed above.
We provide texture maps to the properties diffuse
, roughness
and metalness
as an image. These texture maps can be found online, and some free ones at FreePBR.
Code
-
1. Creating a material
2. Assigning Lighting Model and Texture maps
3. Adding them to the object
The final step is to tell your scene to use an environment map to figure out how to light the object based on its environment.
4. Using an environment mapThis process is similar to how we set a fill earlier and should be straightforward. The objects should look way better with this kind of lighting. Now to use the light estimates like earlier with PBR, we just set the `intensity` of the `lightingEnvironment` in the following method: The `lightingEnvironment` takes value of `1.0` for neutral and ARKit returns a value of `1000` to represent neutral lighting. So scaling this value is essential before assigning it to the lighting environment.
5. Using light estimatesThis should already provide you convincing results with lighting your objects.
Note: After having used this, I’ve obtained some good results although I came across this note on the documentation which says SceneKit falls back to the .blinn lighting model if the renderingAPI
is not metal. Feel free to try it out and see what works best for you.
Moving On
With that, the series on ARKit comes to an end.
Sorry for the delay in finishing this series, I’ve been busy with an AR app that I’ve been working on. Do check it out!
Thanks for following along, I hope the series helped understand how ARKit works and how to get things going at your end. Feel free to leave any comments and feedback!

ic960 Compiler Driver
ic960 is a driver program that manages invocation of the preprocessor,
compiler proper, assembler and linker. The invocation syntax is:
ic960
{ - | / } [ -option ] ...
file ...
Each invocation option must be preceded by a - character.
(On DOS, you can also use a / character.) Click on option
for information on compiler driver options. All options that take
an argument allow optional white space between the option and
the argument. When conflicting options are given, the last one
specified is used. The compiler driver passes the following linker options
and their arguments to the linker: gcdm,
L, l,
m, r,
s, T,
u and x.
The compilation system determines each input file's type by its
filename extension:
- .c
indicates a C source file.
- .i
indicates a preprocessed C source file.
- .s
indicates an assembly language source file.
The compilation system passes any other filename to the linker,
which determines whether the file is an object file, library or
configuration file by its contents.
Other invocation command elements are taken to be either linker
options or object modules, typically produced by an earlier ic960
invocation, or perhaps libraries of compatible routines. These
modules, together with the result of any compilations specified,
are linked (in the order given) to produce an executable program.
When generating COFF modules, the default output filename is a.out.
When generating ELF/DWARF modules, the default filename is e.out.
Each option requires an option delimiter (-
or /).
All options that take an argument allow optional white space between
the option and argument. When conflicting options are given, the
last one specified is used. For information about an option, click
on the option name (underlined).
The ic960 driver also accepts certain linker options.
A
{ CA | CF
| HA | HD | HT | JA | JD |
JF | KA | KB | RP | SA | SB
}
(Architecture)
Compile code for a particular model of the i960 processor. If
the environment variable I960ARCH
is set and non-empty, its value is the default architecture. Otherwise
the default is KB.
a
(ANSI)
Flag non-standard (that is, non-ANSI) constructs. Using a
disables inline assembly language statements and can override
the w (Diagnostic)
option. This option causes the preprocessor macros __STRICT_ANSI__
and __STRICT_ANSI
to be defined.
b size
(Limit Optimizations)
Limit global optimizations for functions exceeding size
instructions. size
is a positive decimal integer.
C
(Keep Comments)
Keep comments in preprocessor output. Works only with E
or P.
Dsymbol[=value]
(Define)
Define a macro with a given value. If =value
is omitted, symbol
is defined to be 1.
Fcoff
| Felf (OMF)
Generate COFF or ELF objects. Fcoff
is the default.
F arg[,arg]...
(Fine-Tune Optimization)
Enable or disable selected optimizations. arg
is one of:
- ai
| noai
- Enables/disables procedure in-lining. Performed only at optimization
level 2. Suppressing in-lining can reduce code size and increase
compilation speed.
- ca
| noca
- Enables/disables code alignment; generate (do not generate)
alignment directives prior to labels that are not entered from
above.
- cb
| nocb
- Enables/disables use of compare and branch instructions.
- lp
- Leaf procedures. Enables code generation of functions using
the bal calling sequence at optimization level 1 or 2. Default
at level 1.
- nolp
- Disables code generation of functions using the bal calling
sequence at optimization level 1 or 2. Default at level 2.
- sa
| nosa
- Determines whether or not the compiler will risk generating
memory references which are not provably aligned. If nosa
is in effect, the compiler occasionally generates potentially
unaligned references when it seems advantageous to do so. When
sa is enabled,
sequences of smaller memory references are used instead of larger
ones which might not be correctly aligned. The default is sa
for C-series and J-series processors.
- sb
- Superblock formation; enabled by default under program-wide
optimization.
- nosb
- Disables superblock formation.
- space
| nospace
- Enable/disable optimizations for memory space savings.
- tce
- Enables conversion of tail calls into branch instructions
at optimization level 1 or 2.
- notce
- Disables conversion of tail calls at level 1 or 2. This is
the default at optimization level 1.
fdb
(Program Database)
All modules subject to program-wide optimization must be initially
compiled with the fdb
option. This option causes the insertion of program database information
in the object modules, and it implies a minimum module-local optimization
level of O1
(although higher module-local optimization levels are allowed).
This option does not otherwise change the code or data generated
for the object modules in any way; it simply makes available to
the global decision making and optimization process information
collected during initial compilation of the modules.
Before using the fdb
option, you should read Chapter 4, Program-Wide Analysis and Optimization,
and Chapter 6, gcdm Decision Maker Option, in the i960 Processor
Compiler User's Guide.
If you intend to use execution profiles when optimizing your application,
you should read Chapter 5, Profile Data Merging and Data Format,
in the i960 Processor Compiler User's Guide.
fprof
(Instrument)
This option inserts execution profile instrumentation code
into the module(s) during compilation, so that when the linked
program is executed, a profile can be collected.
It also implies fdb,
which causes the insertion of program database information in
the object modules, and it implies a minimum module-local optimization
level of O1.
When you compile with the fprof
option, a special profiling library required for profile collection
(libqf)
is linked automatically. If your target environment does not support
file I/O, you must explicitly link an alternate profiling library
(libq).
The profiling libraries provided are identified in Chapter 2 of
the i960 Processor Library Supplement.
Note that when the fprof
compiler option is used in this manner (as distinct from the corresponding
+fprof
gcdm Decision Maker option) the generated object module contains
code that is unsuitable for linking into programs which are not
supposed to collect profile information. To solve this problem,
and avoid having inappropriate instrumentation in widely used
libraries, for example, use +fprof
with the gcdm,subst
option. (The gcdm
option is described in the gcdm Decision Maker Option section
of this hypertext.)
Before using the fprof
option, you should read Chapter 4, Program-Wide Analysis and Optimization,
and Chapter 5, Profile Data Merging and Data Format, in the i960
Processor Compiler User's Guide.

linker. For phase,
p indicates
the preprocessor, c
indicates the compiler, a
indicates the assembler and l
indicates the linker. arg
is an argument to be passed. If the argument contains spaces,
you must enclose the argument in quotation characters ("
").
W [no-]arg
(Warnings)
Enables/disables warnings. With no arg,
this option prints extra warning messages for certain events,
including:
- longjmp()
warnings
- Warn if a nonvolatile automatic variable might be changed
by a call to longjmp().
These warnings are possible only in an optimizing compilation.
-
- The compiler sees only the calls to setjmp().
It cannot know where longjmp()
will be called; in fact a signal handler could call it at any
point in the code. As a result, you may get a warning even when
there is in fact no problem because longjmp()
cannot actually be called at the place that would cause a problem.
- return
and return(value)
- Warn if a function can return either with or without a value.
(Falling off the end of the function body is considered returning
with a value.)
- null effect
- Warn if an expression-statement contains no side effects.
- no-op comparison
- Warn if an unsigned value is compared against zero with <
or <=.
- between-ness comparison
- Warn if a comparison like x<=y<=z
is used; this is equivalent to {(x<=y
? 1 : 0) <=z}, which is a different interpretation
from that of ordinary mathematical notation.
- obsolete storage class specification
- Warn if storage-class specifiers like static
are not the first things in a declaration. According to the ANSI
C standard, this usage is obsolescent.
- partially bracketed initializer
- Warn if an aggregate has a partly bracketed initializer.
arg can
be:
aggregate-return
Warn if any functions return structs or unions.
all
Enable several useful warnings, as indicated in
the list below. Has no Wno-all
form.
cast-align
Warn if a pointer cast may not have required alignment.

and if a non-void function does not return a value. Enabled by
Wall.
shadow
Warn if a local variable shadows another local
variable.
strict-prototypes
Warn if a function is declared without a prototype.
switch
Warn if a switch statement on an enumeration type
does not have a case for each enumerator. Enabled by Wall.
traditional
Warn about constructs that behave differently
under traditional C and ANSI C.

ECB Mersch: We should not breach our promise of no further capital requirements on aggregate
by Ross J BurlandEuropean Central Bank's Yves Mersch is crossing the wires - Full speech
Key comments
- We should not breach our promise of no further capital requirements on aggregate.
- Basel standards should be implemented faithfully.
FX implications
As with ECB's Lane's speech earlier, there is nothing relating to monetary policy or the economy directly hence there has been no market reaction to the press release so far.

| File splitter tool |
Beezer 0.07 onwards comes with tools to split and join files. As you may know :) the File Splitter is used for creating small pieces of a larger file. The File Splitter will not actually break a file into smaller pieces but rather make small pieces from a file, meaning the original file is not altered, only the pieces are created.
The File Splitter can be opened from two places, either from the Welcome window or from the Archive window.
File to split Folder for pieces
When clicked gives a list of recently split files that you can choose from. Clicking the "Select" button lets your browse your computer and choose a file. You can alternatively, directly type in the path of the file in the textbox.
Size of pieces
When clicked gives a list of recently chosen directories. Clicking the "Select" button lets you browse your computer and choose a directory. You can alternatively, directly type in the path of the folder in the textbox. This directory is where Beezer will put the split file pieces.
File number separator
Allows you to specify what is the size of each piece/chunk. You can either choose from a list of pre-defined sizes such as "1.44 MB - (floppy)", "650 MB - (CD)" and so on, or choose "Custom Size" and specify your own size. Please note the minimum size of a piece is 1 byte, and the maximum size being 1 bytes less than the size of the file being split.
Open pieces folder after splitting
By default, File Splitter when splitting a file called MySong.mp3 into 2 pieces, it would create the pieces named, MySong.mp3_01. and MySong.mp3_02. The underscore ("_") here is called the file number separator. The file number separator thus separates the file name from the split order number.
You can thus specify anything in place of the underscore as the file number separator, for example using ".z" for compatibility with WinZip's spanning method and so on.
Currently, digits (0-9), wildcards (* and ?) and path characters (: and /) are not allowed. Other than that you can enter anything.
Close window after splitting
If this option is checked, after splitting of the file is complete, the folder in which the pieces were created is automatically opened.
Create self-joining executable
Closes the File Splitter tool after splitting is complete. If the split operation is cancelled, the window isn't closed even if this option is specified.
If this option is checked, Beezer will create a Haiku executable file in the pieces folder, that when run will automatically re-join the pieces to create the original file.
This executable is a Haiku executable and cannot be run from Windows. Also this executable can be run from a system that does not have Beezer installed. It is completely independent of Beezer and would be useful if you are sending the split files to someone who has Haiku or other flavours of it and whom does not have Beezer. It is also very useful for quickly re-joining the files and is faster than opening Beezer, and using the File Joiner tool.
Note:Number of pieces
For the self-joining executable to work it must be placed in the SAME directory as the pieces and the pieces should NOT be renamed, as the executable contains information about the pieces and it's file number separators.
File size
Shows you how many pieces will Beezer end-up creating for the specified size of pieces and the file size. Note, Beezer cannot create any more than 32767 pieces.
Split!
Shows you the size of the file that is to be split.
! Tip
Clicking this would start the split process. This process can safely be cancelled before it completes. Beezer will delete any partially created pieces, but whatever pieces are fully created will not be deleted.
You can choose files to split from the Tracker by dropping them on the File Splitter window. Also, you can drop a folder on the File Splitter window to specify the folder for creating the pieces.

This is a nifty assignment from 2017 proposed by Kunal Mishra. Source
The purpose of this assignment is to learn to
Create the game 2048 using the Bridges API. Being under the MIT license the game can be found in a variety of places online if the game is unfamiliar. The basics is each turn a new tile spawns on a 4x4 grid that contains the value 2 and rarely 4. The player can choose any cardinal direction to move all blocks at one time. Once all blocks have reached either the edge or another block they stop and the player can choose another direction. If two blocks have the same value instead they merge and the values are added together. The ultimate goal of the game is to get the value 2048 on a tile. The player loses if they are unable to make a move.
There needs to be an object that represents a game tile. It holds a position and a value. Each tile takes up 1/4th of the grid in both directions.
When the player hits an arrow key the tiles should move until they either merge or they hit a wall/other tile that cannot be merged. While the tiles are moving the game should be a state that does not receive input. Once all tiles are moved or merged then the player can input the next move. After each turn the game should check if there is a game over (no moves to make) or the player has won (a tile has value 2048).

SeaSurf is a Flask extension for preventing cross-site request forgery (CSRF).
CSRF vulnerabilities have been found in large and popular sites such as YouTube. These attacks are problematic because the mechanism they use is relatively easy to exploit. This extension attempts to aid you in securing your application from such attacks.
This extension is based on the excellent Django middleware.
Install the extension with one of the following commands:
$ easy_install flask-seasurf
or alternatively if you have pip installed:
$ pip install flask-seasurf
Using SeaSurf is fairly straightforward. Begin by importing the extension and then passing your application object back to the extension, like this:
import Flask
from flaskext.seasurf import SeaSurf
app = Flask(__name__)
csrf = SeaSurf(app)
This extension is configurable via a set of configuration variables which can we added to the Flask app’s config file. The cookie name, cookie timeout, and CSRF disabled parameters may be set via CSRF_COOKIE_NAME, CSRF_COOKIE_TIMEOUT, and CSRF_DISABLED, respectively.
Corrosponding code will need to be added to the templates where POST, PUT, and DELETE HTTP methods are anticipated. In the case of POST requests a hidden field should be added, something like this:
<form method="POST">
...
<input type="hidden" name="_csrf_token" value="{{ csrf_token() }}">
</form>
The extension adds a global function to the Jinja template engine called csrf_token. This is a function that retrieves the current token and will be matched against the request token.
By default all requests that are not GET, HEAD, OPTIONS, or TRACE are validated against the CSRF token sent by the client and as rendered on the page. However a view may be completely exempted from validation using the exempt decorator. For instance it’s possible to decorate a view as shown below:
@csrf.exempt
@app.route('/exempt_view', methods=['POST'])
def exempt_view():
'''This view is exempted from CSRF validation.'''
return 'foobar'
AJAX is not exempted from CSRF validation as it is a plausible vector for cross-site request forgery. As such, POSTing with AJAX can make use of the aforementioned method, but other HTTP methods, such as PUT and DELETE might be better suited to using the X-CSRFToken header instead.
Essentially this header is passed back to the backend by way of extrating the token from the cookie using JavaScript. For a better explanation of how this might be done please refer to the `Django CSRF documentation <https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax >`_.
Primary class container for CSRF validation logic. The main function of this extension is to generate and validate CSRF tokens. The design and implementation of this extension is influenced by Django’s CSRF middleware.
Tokens are generated using a salted SHA1 hash. The salt is based off your application’s SECRET_KEY setting and a random range.
You might intialize SeaSurf something like this:
csrf = SeaSurf(app)
Validation will now be active for all requests whose methods are not GET, HEAD, OPTIONS, or TRACE.
When using other request methods, such as POST for instance, you will need to provide the CSRF token as a parameter. This can be achieved by making use of the Jinja global. In your template:
<form method="POST">
...
<input type="hidden" name="_csrf_token" value="{{ csrf_token }}">
</form>
This will assign a token to both the session cookie and the rendered HTML which will then be validated on the backend. POST requests missing this field will fail unless the header X-CSRFToken is specified.
Excluding Views From Validation
For views that use methods which may be validated but for which you wish to not run validation on you may make use of the exempt decorator to indicate that they should not be checked.
| Parameters: | app – The Flask application object, defaults to None. |
|---|
A decorator that can be used to exclude a view from CSRF validation.
Example usage of exempt might look something like this:
csrf = SeaSurf(app)
@csrf.exempt
@app.route('/some_view')
def some_view():
"""This view is exempt from CSRF validation."""
return render_template('some_view.html')
| Parameters: | view – The view to be wrapped by the decorator. |
|---|
Initializes a Flask object app, binds CSRF validation to app.before_request, and assigns csrf_token as a Jinja global.
| Parameters: | app – The Flask application object. |
|---|


Blocks, Procs, and Lambdas are powerful aspects of the Ruby language. Although they are similar in many ways, depending on your objective, it might make sense to choose one over the others. So, what are each of them and how do they differ?
Blocks & Procs
Lets say that we have an array of numbers that we want to adjust in several ways:nums = [1,2,3,4,5,6,7,8,9,10]
We might add 2 to every number by typing something like this:p nums.map! {|num| num + 2}
[3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
What did we do there, exactly? Well, the map! method knows to iterate through each object within the nums array. For each object in the array, the map! method executes the instructions passed to it in the block of code to the right (within the { }). This block of code takes each object in the array as an input, assigns it the temporary variable name 'num', and then changes that num by adding 2.What's important to take away here, though, is that the instructions we passed to the map! method were in a block. A ruby block is set of code that can be executed, and is one of the few items in ruby that is not considered an object.
But what if our plan was to increment this array several times? We might get tired of continually typing
p nums.map! {|num| num + 2}
everytime we wanted to increment the array. Instead, we could save those instructions as a Proc that we can access by name. A proc is essentially just a block of code that is saved with a variable name to be accessed later. We could establish a Proc that will increment our array like this:add_2 = Proc.new {|num| num + 2}
And now if we want to increment the array 3 times, we can just write:
p nums.map!(&add_2)
p nums.map!(&add_2)
p nums.map!(&add_2)
[3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
[5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
[7, 8, 9, 10, 11, 12, 13, 14, 15, 16]
temp = Proc.new {|num| num > 12 ? "hot" : num.between?(9,12) ? "warm" : "cold"}
p nums.map(&temp)
["cold", "cold", "warm", "warm", "warm", "warm", "hot", "hot", "hot", "hot"]
p nums.map!(&add_2)
p nums.map(&temp)
[9, 10, 11, 12, 13, 14, 15, 16, 17, 18]
["warm", "warm", "warm", "warm", "hot", "hot", "hot", "hot", "hot", "hot"]
As you can see, the use of Procs not only saves you time, but also prevents unnecessary repetition and can help make your code even easier to read.
Procs vs. Lambdas
A lambda is another way of storing a block of code, and only differs from Procs slightly. The two major differences between a lambda and a Proc are that:- A lambda checks that the amount of arguments passed into it is correct. For example, if a lambda expects 3 arguments to be passed in, and only 2 are, the code will not execute and will return an error. If you pass in fewer arguments than are available for a Proc, a value of nil will automatically be applied to any unfulfilled arguments. Any unexpected arguments will be ignored.
- A lambda will 'return' back to a method that it is built into, whereas a Proc will break the calling method. For example, if you access a lambda from within a method, and that lambda includes a 'return' function, it will break you back into the method it was called from, and any remaining code within the method will be run. If you accessed a Proc from a method, and 'returned' from that Proc, you will break out of the method and the remaining code within that method will not be run.
def greet(person)
--greeting = lambda {return "Hey there #{person}!! So great to talk to you!"}
--puts greeting.call
--"How are things going?"
end
puts greet("craig")
Hey there craig!! So great to talk to you!
How are things going?
def greet(person)
--greeting = Proc.new {return "Hey there #{person}!! So great to talk to you!"}
--puts greeting.call
--"How are things going?"
end
puts greet("craig")
Hey there craig!! So great to talk to you!
Notice how only the string within the Proc was returned, and not the second one like when we used a lambda? That's because when returning out of a Proc, the method from which we accessed that Proc is broken out of. Returning out of a lambda takes us right back to where we were within the method.As you can see, blocks, Procs, and lambdas are very powerful. Which one you use at which point in time will be dictated by the functionality you are trying to build, and whether you'll want to re-use that functionality several times over.
Thanks for reading!

ArticleImage
A class for images in WeChat articles.
You'll find this in the returned array of WeChatArticle#getMedia. You
can use instanceof
to find out if that element is an image.
This library itself doesn't handle images, since many problems are closely
related to your implementations. But we do provide a set of API for easier
image handling. You can get the URL, remove it out of the article and set a
new URL to where you caches all images. Additionally you can directly stream
the image, and clean up that
for cleaner markup.

Some system has written in Bootstrap2 (example: Joomla CMS), but when Bootstrap3 release, it's not backward compatible.
This adapter can help developer working in Bootstrap 2 & 3 syntax that will not break their system when migrating to version 3, or make Bootstrap 2 system be flatten styles.
Now, a website written in Bootstrap 2 will be Bootstrap 3 flatten styles.
Buttons
Default buttons
Button styles can be applied to anything with the .btn class applied. However, typically you'll want to apply these to only <a> and <button> elements for the best rendering.
Button
class=""
Description
btn
Standard gray button with gradient
btn btn-primary
Provides extra visual weight and identifies the primary action in a set of buttons
btn btn-info
Used as an alternative to the default styles
btn btn-success
Indicates a successful or positive action
btn btn-warning
Indicates caution should be taken with this action
btn btn-danger
Indicates a dangerous or potentially negative action
btn btn-inverse
Alternate dark gray button, not tied to a semantic action or use
btn btn-link
Deemphasize a button by making it look like a link while maintaining button behavior
Cross browser compatibility
IE9 doesn't crop background gradients on rounded corners, so we remove it. Related, IE9 jankifies disabled button elements, rendering text gray with a nasty text-shadow that we cannot fix.
Button sizes
Fancy larger or smaller buttons? Add .btn-large, .btn-small, or .btn-mini for additional sizes.
Heads up!
We use .disabled as a utility class here, similar to the common .active class, so no prefix is required. Also, this class is only for aesthetic; you must use custom JavaScript to disable links here.
As a best practice, try to match the element for your context to ensure matching cross-browser rendering. If you have an input, use an <input type="submit"> for your button.
Images
Add classes to an <img> element to easily style images in any project.

NOVEMBER 30 St Andrew, Apostle
FIRST
A reading from the letter of St Paul to the Romans 10:9-18
Brethren: If you
confess with your lips that Jesus is Lord and believe in your heart that God
raised him from the dead, you will be saved. For man believes
with his heart and so is justified, and he confesses with his lips and so is
saved. The scripture says, "No one who believes in him will be put
to shame." For there is no distinction between Jew and Greek; the same
Lord is Lord of all and bestows his riches upon all who call upon him. For,
"every one who calls upon the name of the Lord will be saved." But
how are men to call upon him in whom they have not believed? And how are they
to believe in him of whom they have never heard? And how are they to hear
without a preacher? And how can men preach unless they are sent? As it is
written, "How beautiful are the feet of those who preach good news!" But
they have not all obeyed the gospel; for Isaiah says, "Lord, who has
believed what he has heard from us?" So faith comes from what is heard,
and what is heard comes by the preaching of Christ. But I
ask, have they not heard? Indeed they have; for "Their voice has
gone out to all the earth, and their words to the ends of the world."
The word of the Lord.
RESPONSORIAL PSALM Psalm 19
R. Their sound goes forth through all the earth.
The heavens declare
the glory of God, and the firmament proclaims the work of his hands. Day unto
day conveys the message, and night unto night imparts the knowledge.
R. Their sound goes forth
through all the earth.
No speech, no word, whose
voice goes unheeded; their sound goes forth through all the earth, their message
to the utmost bounds of the world.
R. Their sound goes forth
through all the earth.
ALLELUIA
R. Alleluia. Follow me, says the Lord, and I will make you fishers of men. R. Alleluia.
GOSPEL
A reading from the holy Gospel according to Matthew 4:18-22
At that time: As Jesus
walked by the Sea of Galilee, he saw two brothers, Simon who is called Peter
and Andrew his brother, casting a net into the sea; for they were fishermen. And
he said to them, "Follow me, and I will make you fishers of men." Immediately
they left their nets and followed him. And going on from there he saw two other
brothers, James the son of Zebedee and John his
brother, in the boat with Zebedee their father,
mending their nets, and he called them. Immediately they left the boat and
their father, and followed him.

The Extension Mechanism

Creating and Using Extensions
Understanding Extension Class Loading
The extension framework makes use of the class-loading delegation mechanism.
When the runtime environment needs to load a new class
for an application, it looks for the
class in the following locations, in order:
- Bootstrap classes: the runtime classes in
rt.jar, internationalization classes in i18n.jar,
and others.
- Installed extensions: classes in JAR files in the
lib/ext directory of the JRE,
and in the system-wide, platform-specific extension directory
(such as /usr/jdk/packages/lib/ext
on the Solaris™ Operating System,
but note that use of this directory applies only to Java™ 6 and later).
- The class path: classes,
including classes in JAR files, on paths specified by the
system property java.class.path. If a JAR file on the class path has
a manifest with the
Class-Path
attribute,
JAR files specified by the Class-Path
attribute
will be searched also.
By default, the java.class.path
property's value
is .
, the current directory.
You can change the value by using the
-classpath or -cp command-line options, or
setting the CLASSPATH
environment variable.
The
command-line options override the setting of the CLASSPATH
environment variable.
The precedence list tells you, for example, that the class path is
searched only if a class to be loaded hasn't been found among the
classes in rt.jar, i18n.jar or the installed extensions.
Unless your software instantiates its own class loaders for
special purposes, you don't really need to know much more than to
keep this precedence list in mind. In particular, you should be
aware of any class name conflicts that might be present. For example,
if you list a class on the class path, you'll get unexpected
results if the runtime environment instead loads another class
of the same name that it found in an installed extension.
The Java Class Loading Mechanism
The Java platform uses a delegation model for
loading classes. The basic idea is that every class loader has a
"parent" class loader. When loading a class, a class loader first
"delegates" the search for the class to its parent class loader before
attempting to find the class itself.
Here are some highlights of the class-loading API:
- Constructors in java.lang.ClassLoader and its subclasses
allow you to specify a parent when you instantiate a new class loader.
If you don't explicitly specify a parent, the virtual machine's system
class loader will be assigned as the default parent.
- The loadClass method in ClassLoader performs
these tasks, in order, when called to load a class:
- If a class has already been loaded, it returns it.
- Otherwise, it delegates the search for the new class
to the parent class loader.
- If the parent class loader does not find the class,
loadClass calls the method findClass
to find and load the class.
- The findClass method of ClassLoader searches
for the class in the current class loader if the class wasn't found by
the parent class loader. You will probably want to override this method
when you instantiate a class loader subclass in your application.
- The class java.net.URLClassLoader
serves as the basic class loader for extensions
and other JAR files, overriding the findClass method of
java.lang.ClassLoader to search one or more specified URLs for
classes and resources.
To see a sample application that uses some of the API as it
relates to JAR files, see the
Using JAR-related APIs lesson in this tutorial.
Class Loading and the java Command
The Java platform's class-loading mechanism
is reflected in the
java command.
- In the java tool, the
-classpath option is a shorthand way to set the
java.class.path property.
- The
-cp and -classpath options are equivalent.
- The -jar option runs applications
that are packaged in JAR files. For a description and examples of
this option, see the
Running JAR-Packaged Software lesson in this tutorial.


Dogs are very useful for humans. Thanks to the relation with them, their incredible intelligence and smell. In some cases, they are used to replace a human work.
Dogs help people who need it in their life. These people can be blind, or disabled.
Service dog
Service dogs (or also seeing-eye dogs) have a very powerful friendship with the owner. They participate in a long training in order to be attentive to the environment.
Seeing-eye dog
In the street, he warns about the presence of steps, pedestrian crossing, etc.
They are very obedient. They can also memorize daily routes, disobey to protect their master, recognize some shops of infrastructures like bus stops, etc.
Over the utility, they are also a very good emotionnal support.
Assistance dog
Assistance dogs are not very different. They can do more actions, to meet the needs of the disabled.
They can turn on/off the light, open a door or the fridge, pick-up and give objects, bark to warn and stay calm in any cases.
Dogs are not only intelligent. They also have a powerful smell that can be used by customs, DEA, Search and Rescue and M.D. for diseases detection.
Customs and DEA
Customs and DEA use dogs with their sense of smell to detect drugs. That is a very good help for them because they can smell a lot of luggages at once and detect it. No X-Ray or opening is necessary. Some criminal tried to trick the dog's nose, by concealing the smell with other smells like chilli pepper, coffee, etc. Unfortunately (or fortunately), it doesn't work.
In comparison with us, for a hamburger, we smell hamburger. The dogs' nose works differently. Dogs smell bread, tomato, salad, meat, cheese and ketchup. They can separate every elements.
Customs also used them to detect explosive material, gun powder and money.
Search and Rescue
The rescue teams in mountains and on the beach uses dogs to detect lost people. In mountains, people stuck under snow after an avalanche is very hard to find. Fortunatly, the dog can found them only with the nose. That is very impressive. If founded, the dog will start to dig and get the human out of the snow.
In the sea, dogs are not well used but they can swim and help drowning persons to reach the beach.
Medical
Recently in medicine, scientists discovered that dogs can detect a dozen of diseases like melanoma, cancer and most recently, COVID-19. Actually they detect a difference of body odor due to desease. They are trained to detect this pretty slight difference.
Everyone knows that dogs can also be dangerous or agressive. Some people are scared of them. They can be used as a weapon or only as dissuasive weapon.
Hunt
Hunters like dogs because they are small, fast and like to chase prey. That is a perfect teammate during a hunt.
Security
Security dogs are used to be dissuasive. They are selected and trained for their size, muscles and their obedience.
Military
A lot of countries use dogs in their army for different roles. They serve to protect an area and make sure nobody will try to entry. They bark if someone is hidden. Another type of dogs is similar but used for their discretion.
Messenger dogs are trained to deliver a package to the receiver. They are very discreet to be sure package is not intercepted.
Mine dogs are trained to sniff the ground and prevent mine placed by ennemies.


Hello my name is Brenasia and I am a soon to be junior at arsenal tech. I strive to be greater then what's expected of me. People around me would describe me as respectful, sociable, and a thinker. I work well in groups because I'm always open to explore others ways of thinking, but I am also capable of working on my own.
I wanted to begin coding because it is the way of the future. By learning now I believe I will be able to think more critically about tech and how it works

The Beacon Food Forest (BFF) started in 2009 as a result of a permaculture design course final project. To pass the course four students selected the BFF's actual site and created a dream design which demonstrated all the design elements we had learned in the course. The best tools to come out of this final project were a full size landscape design drawing, which we used to present our concept to the community and Seattle City agencies, along with the language to support this design. The schematic designs below held a lot of leverage. The design, drawn by a certified Landscape Architect, fit the actual topography of the site and had massive community support and input.
As volunteers we are doing our best to both build a public food forest and offer help to others who are thinking of building a food forest. If you find this advice helpful please consider a donation.
As of May 2013 we are continuing to work on the hardscaping, water supply and plant bed building as well as ongoing community engagement. We plan on planting the understory dwarf trees, shrubs and perennials in the fall of 2013 and open our P-Patch beds by late winter 2014.
The Beacon Food Forest values renewable resources and services while following Permaculture Principles (PCP). Read more about our plan: How We Got Started.
| Steps: | Permaculture Principles: |
|---|---|
| Step 1: Find the land. | Observe and Interact. |
| Step 2: Find a core group of dedicated believers. | Integrate rather than segregate. |
| Step 3: Introduce the BFF Concept to the Community. | Use and value diversity. |
| Step 4: Create a relationship with the landlord and begin negotiations. |
Use and value renewable resources and services.
Apply self regulation and accept feedback. |
| Step 5: Create leverage. | Creatively use and respond to change. |
| Step 6 : Continuous Outreach and Community Engagement. | Use edges and value the marginal. |


Events
Basic Usage
The Laravel event facilities provides a simple observer implementation, allowing you to subscribe and listen for events in your application. Event classes are typically stored in the app/Events
directory, while their handlers are stored in app/Handlers/Events
.
You can generate a new event class using the Artisan CLI tool:
php artisan make:event PodcastWasPurchased
Subscribing To An Event
The EventServiceProvider
included with your Laravel application provides a convenient place to register all event handlers. The listen
property contains an array of all events (keys) and their handlers (values). Of course, you may add as many events to this array as your application requires. For example, let's add our PodcastWasPurchased
event:
/**
* The event handler mappings for the application.
*
* @var array
*/
protected $listen = [
'App\Events\PodcastWasPurchased' => [
'App\Handlers\Events\EmailPurchaseConfirmation@handle',
],
];
To generate a handler for an event, use the handler:event
Artisan CLI command:
php artisan handler:event EmailPurchaseConfirmation --event=PodcastWasPurchased
Of course, manually running the make:event
and handler:event
commands each time you need a handler or event is cumbersome. Instead, simply add handlers and events to your EventServiceProvider
and use the event:generate
command. This command will generate any events or handlers that are listed in your EventServiceProvider
:
php artisan event:generate
Firing An Event
Now we are ready to fire our event using the Event
facade:
$response = Event::fire(new PodcastWasPurchased($podcast));
The fire
method returns an array of responses that you can use to control what happens next in your application.
You may also use the event
helper to fire an event:
event(new PodcastWasPurchased($podcast));
Closure Listeners
You can even listen to events without creating a separate handler class at all. For example, in the boot
method of your EventServiceProvider
, you could do the following:
Event::listen('App\Events\PodcastWasPurchased', function($event)
{
// Handle the event...
});
Stopping The Propagation Of An Event
Sometimes, you may wish to stop the propagation of an event to other listeners. You may do so using by returning false
from your handler:
Event::listen('App\Events\PodcastWasPurchased', function($event)
{
// Handle the event...
return false;
});
Queued Event Handlers
Need to queue an event handler? It couldn't be any easier. When generating the handler, simply use the --queued
flag:
php artisan handler:event SendPurchaseConfirmation --event=PodcastWasPurchased --queued
This will generate a handler class that implements the Illuminate\Contracts\Queue\ShouldBeQueued
interface. That's it! Now when this handler is called for an event, it will be queued automatically by the event dispatcher.
If no exceptions are thrown when the handler is executed by the queue, the queued job will be deleted automatically after it has processed. If you need to access the queued job's delete
and release
methods manually, you may do so. The Illuminate\Queue\InteractsWithQueue
trait, which is included by default on queued handlers, gives you access to these methods:
public function handle(PodcastWasPurchased $event)
{
if (true)
{
$this->release(30);
}
}
If you have an existing handler that you would like to convert to a queued handler, simply add the ShouldBeQueued
interface to the class manually.
Event Subscribers
Defining An Event Subscriber
Event subscribers are classes that may subscribe to multiple events from within the class itself. Subscribers should define a subscribe
method, which will be passed an event dispatcher instance:
class UserEventHandler {
/**
* Handle user login events.
*/
public function onUserLogin($event)
{
//
}
/**
* Handle user logout events.
*/
public function onUserLogout($event)
{
//
}
/**
* Register the listeners for the subscriber.
*
* @param Illuminate\Events\Dispatcher $events
* @return array
*/
public function subscribe($events)
{
$events->listen('App\Events\UserLoggedIn', 'UserEventHandler@onUserLogin');
$events->listen('App\Events\UserLoggedOut', 'UserEventHandler@onUserLogout');
}
}
Registering An Event Subscriber
Once the subscriber has been defined, it may be registered with the Event
class.
$subscriber = new UserEventHandler;
Event::subscribe($subscriber);
You may also use the Laravel IoC container to resolve your subscriber. To do so, simply pass the name of your subscriber to the subscribe
method:
Event::subscribe('UserEventHandler');


When my 4 cyl YJ's transmission started to grind going into 3rd gear
I started to look for alternatives. The AX-5 that came in my Jeep
and most 4 cyl YJ's is not a bad transmission for the stock Jeep,
but when you swap on larger tires and start wheeling frequently, it
is only a matter of time.
Since my Jeep is spending more time off road I wanted a transmission
that could take abuse and enhance my Jeeps performance. After some
research I decided on the GM SM420 transmission. This transmission
was used on trucks up to 2 1/2 tons so it will stand up to anything
my 4 cyl can throw at it.
Pros
Besides the fact this transmission can take the off road abuse there are
some other benefits. The first gear ratio is 7.05:1 vs the stock AX-5
first gear ratio of 3.93:1. This greatly increases off road performance
when rock crawling, or tackling steep climbs and descents. This gives
a much greater level of control, and eases the level of abuse to other
components. The stock crawl ratio is 43:1 and the SM420 increases this
to 78:1. A very significant increase!

The overall length of the trans is shorter than the stock combo, the
rear driveline can be lengthened about 3/4" of an inch. Every bit
helps when dealing with a short wheelbase vehicle like a Jeep. Most
other transmissions that offer the same benefits are longer than the
SM420.
With this transmission, if you decide to swap in Chevy power at
a later date you will be ready, only needing a bell housing and
clutch component change depending on what engine you choose.
With the Advance Adapter kit , it is possible to switch to a Dana 300
transfercase just by switching the spud shaft that comes with the kit.
Of course that would only be if switching the front axle to a passenger
side pumpkin, as in a conversion to Scout axles.
Cons
The street performance with the four cylinder will suffer a little,
you seldom use 1st gear on the street, and there is a big gap between
3rd and 4th. You lose fifth gear altogether, but if you are running
big tires then it's not used much anyway. First and reverse are non
synchronized, you will have to be stopped for these to engage
smoothly. Of course reverse isn't synchronized on the AX-5 either.
 The SM420
is an old truck transmission and it doesn't shift as lightly or as
quickly as the stock transmission. Definitely not for drag racers.
It is louder than the stock tranny, especially first thru third.
Fourth is about the same as the original transmission.
There is no provision for reverse lights on most SM420's so you will
have to wire in a switch for this purpose.
Hard parts, like gears and shafts are no longer available from GM, but
synchros, bearings and gaskets can be had from 4x4 shops such as Hicks
4x4, or Border Parts. However, the transmission themselves are cheap
and if a gear or shaft is needed, a whole trans can be obtained for less
than $100 US in most salvage yards.
What to look for in an SM420
The SM420 was used in Chev and GM 1/2 to 2 1/2 ton trucks from 1947
thru 1967. There are some differences you might want to look for.
I don't know the cutoff years but later SM420's have a front bearing
retainer with an oil seal on the input shaft, earlier units have an
oil deflector that can't always do the job when being turned at the
revolutions four cylinders are capable of. This results in a small
amount of oil leaking out and while usually not causing any problem,
it smells, and could find it's way onto the clutch, causing slipping
problems.
Some SM420's have a tubular shifter and some have a forged shifter,
the forged shifter is easier to bend, it can be heated with a torch and
pulled into the position you want, whereas the tubular lever tends to
collapse when bending. The shifter will have to be bent to give your
hand clearance at the dash when shifting to first and third.
Very late SM420s have a reverse light switch.
Bell Housing and Clutch
The bell housing used for this swap is the bell housing from an 1986
Chevy S-10 with a 2.8 V6 and a five speed. The hydraulic slave
cylinder, pressure plate, throwout bearing, clutch release fork,
and fork pivot ball from the S-10 are also used. The clutch disk
to use is from a 83 Jeep CJ-7 with a 4 cyl engine. The original
pilot bushing from the YJ can be used.
Some of the original bellhousing mounting bolts are too long and will
have to be replaced. The bellhousing has to have some modifications.
The two lower transmission mounting holes have to be drilled out to
fit the SM420 bolts, cap screws will have to be used because of the
limited room inside the bellhousing. I had to have the cap screws
turned down to fit. It was suggested to have these holes spot faced
in a milling machine for a flat contact surface with the screw, a
good idea.
The starter cone has to have a piece taken out to fit the Jeep starter.
A new inspection cover will have to be made, or the S-10 or YJ cover
must be modified to fit.
The clutch release fork, pivot ball stud has a thick washer under it,
this has to be removed or the clutch fork will hit the pressure plate.
I used Locktight on the ball pivot stud. I also ground off a small
amount on the clutch fork at the top of the pivot ball divot for
a little extra clearance.
Crank sensor
A bracket must be made to hold the crank position sensor, I had a local
machine shop do this, and took them the old bellhousing for a guide.
 This is very important to
get right, in too far and the flywheel will eat your sensor, not enough
and your engine won't run.
Clutch slave cylinder
The transmission needs one of the mounting ears ground down a little
for clearance when mounting the slave cylinder.

|
Before
|
After
|
A new line needs to be made to adapt the S-10 slave cylinder to the
YJ clutch line. Since the 91's have the line as an integral part
of the clutch master cylinder I decided to keep the quick disconnect and
had a local hydraulic shop make up a line with fittings to mate the two
together. I used a coat hanger bent to the shape necessary, and gave
that to the shop for a guide.
Transmission Tunnel
A notch has to be cut in the floor pan for clearance of the shift tower,
I cut two but believe now only one is necessary, see the picture for
details. The tunnel cover also needs to modified for the new shifter
position. The transmission lever also needs to be bent so that it
will clear the dash.
Skid Plate
The skid plate will need a notch cut for the transmission oil drain
plug. This is at the very front of the skid plate and I cut mine
with an angle grinder.
Drive Shaft
The front driveshaft must be shortened 3/4", this is important, because
the shaft if not shortened could be pushed through the transfer case,
ruining the whole case. My rear shaft is a little too short but good
enough. I am waiting to modify it when I do another lift in the
future.
Transfercase Mounting
The transfercase is adapted to the SM420 using Advance Adapters kit
#50-9703, the kit uses the stock transmission mount and shift linkage
mounts. The top two bolts of the transfercase shifter linkage are
no longer used and the shifter is a little unstable, this could be fixed
by using a piece of flat stock and running it to one of the transmission
cover bolts. The shift lever comes through the floor in almost the
same location as stock.
Conclusion
That's about it, I love this transmission off road. It is
just about bomb proof! The Swap is not difficult and was the first
time I took out a transmission by myself. It does demand some caution
in the placement of the crank sensor, and attention to details, but
overall I consider it well worth the effort.

Dairy Farm Management System @ 2020. Development Team


When running into a problem when I think I done it right is really frustrating, causes a disproportionate emotional response. And as the frustration builds, I start to overlook simpler things and this is when it is a good time to take a break and come back later to tackle the issue or if possible, ask help from someone.
One example is when I was doing the Minesweeper task. I could not figure out why the counting cells function only returns 1 and the cause was as simple as misplaced "return"
Although I found it quite difficult to recreate the negative experience, I found the exercise to be useful.
I would imagine that we would encounter frustation quite often once we hit bootcamp, not that is a bad thing. Hopefully with this technique (especially the stop/breathe part) we could overcome it and respond positively.

Are there some specifications for intermediate representation Lean uses? If so, where can I find them?
How can I dump the IR of a given lean program?
Thanks,
Matt
Do you mean something like the export format? https://github.com/leanprover-community/lean/blob/master/doc/export_format.md The type theory is explained in https://github.com/digama0/lean-type-theory
Another interesting IR is the bytecode used by the VM (which is used by #eval
and for tactics). You can view the generated bytecode by enabling an option:
set_option trace.compiler.optimize_bytecode true def foo (x : nat) := x + 42
Thanks for the responses Gabriel. I think the Bytecode IR is interpreted in the lean3 system is that correct? I am looking more in the direction of the lean4 IR, basically, the one described in the 'Counting Immutable Beans' as the lambda pure IR.
https://github.com/leanprover/lean4/
Thanks as well Anton, is this IR only used for typechecking?
Oh it took a while to click, I understand now, everything is done by set_options command in the .lean file ( so set_option trace.compiler.labda_pure true)
Thanks for the help!
Hey, what exactly is the difference between the IRs generated by these two commands?
set_option trace.compiler.ir.init true
set_option trace.compiler.lambda_pure true
Can I assume they are semantically equivalent? From anecdotal evidence on small programs they seem to produce the same code, but just show lambda-calculus functions in more 'traditional' style.
(deleted)
The Lean 4 compiler has 2 distinct phases, one where it treats the code as pure functional code, which lambda_pure
seems to print results from, and one where it uses the IR and treats it as imperative code. In functional transformations, you have things like common subexpression eliminations and constant folding and I'm not sure if lambda_pure
includes those. If it does include all of those, you could see lambda_pure
as the output of the functional phase and ir.init
as the input of the next phase. I recommend looking through the Lean source code for lambda_pure
and seeing if it has done all the functional optimizations at the time where it prints it.
No, they are exactly the same IR. The only difference is that lambda_pure
is traced from C++ and ir.init
from Lean. One of them could be removed.
OK great! Thanks for the answer Sebastian, very helpful.
Also thank you Simon! I am fairly sure lambda pure includes those as it is written in the paper, that exactly the way I am looking at it so far (output of the functional phase)
