The below pointers are taken from this article: How to Design the Perfect Single Page Website.
By default, all a user needs to know to navigate a single page site is how to scroll. You might include arrows or other navigational clues, but with rare exception, simply scrolling will bring your visitors from one section to the next.
While this one is not a given, a well-coded single page site is probably going to be faster to code than a multi-page site. The design process can sometimes take less time, though that depends on how complex the single page is going to be.
This one builds off the previous point. When you only have a single page to work with, you have to simplify things to their most essential components. No more pages and pages of useless marketing propaganda. You have to get to the point right away.
Quality inbound links are a big part of how well a website performs in search engines. While search engines aren’t necessarily the largest traffic source for a lot of sites, they’re still generally important. By only having one page, you only have one page being linked to. That can increase the importance of the site as far as search engines go.
Single page sites often use a storytelling angle that multi-page sites aren’t as good at. This can increase conversions and inspire visitors to take action.
There are no more endless lists of pages and sub-pages to organize. No more wondering if this page or that page should be a parent or a child. No more huge navigation menus and sub-menus. It’s all on one page. And whether you decide to include navigational links, or simply let users scroll, is up to you and whether you think it will add to the user experience or not. That’s just not an option when a site has multiple pages.
While this isn’t as much of an issue on the hosting end anymore, consider how many users are accessing your site using mobile devices these days. Decreasing the amount of bandwidth your site takes is appreciated by users with limited data plans.
A single-page site is, by necessity, not complex. Making the design responsive is generally easier. Simplified navigation and similar changes also make a design that works well on small screens easier.

Project Description
A space-themed, touch-controlled game for the Windows Tablet (sorry that the gif was recorded on PC). Along with three friends, I programmed for 24 hours straight to
create a playable game with smooth, intuitive touch/gesture controls. I was also heavily involved
in the design phase before the hackathon where we decided what the game would be.

Perseus with the head of Medusa
Created by Antonio Canova between 1800 and 1801. and acquired by Pius VII the next year (for 3000 guilds) along with two other statues. Canova portrayed the triumphant Perseus at the moment when he cut off the head of the Gorgon Medusa with the sickle received from Athena. Canova's ice classicism is superior even in such a bloody scene as this one, where the Argive hero holds the head of Medusa with a wide and calm gesture of restrained victory, whose face, posthumously stiff, has only slightly twisted in pain.

Choosing the sample integration to create first
You can create the sample integrations in any order. To help you decide which one to try first, the following table compares them.
|
|||
What it does |
Captures and filters tweets that mention a particular Twitter user. For tweets that contain specified text, the integration passes data related to the tweet to Salesforce and Salesforce creates a new contact. |
Captures updates in Salesforce and then calls a database stored procedure to synchronize a particular database table with the Salesforce updates. |
Obtains delivery records from a Red Hat AMQ broker, executes a custom step to identify any items that were damaged when they were received, and connects to a REST API to provide contact information for vendors of damaged items. |
What you learn about |
Connecting to Twitter and Salesforce, how {prodname} interfaces with applications that use the OAuth protocol, mapping data fields received from one application to fields that the next connected application in the integration can operate on, filtering data to determine whether to continue integration execution. |
Connecting to Salesforce and a SQL database, OAuth support, data mapping, how to update a SQL database as part of an integration. |
Connecting to a Red Hat AMQ broker and a REST API, data mapping, uploading extensions for a step and for a REST API client connector, using a custom step and a custom API client connection. |

Graffiti Stencil Tutorial
1. Choosing your Image
First things first, you need to choose an image that will make a good stencil (or draw your own).
Too much detail is hard to cut out and the stencil will become weak.
2. Designing the Stencil
The next step is to pick out the darkest and lightest parts of the image.
Squinting at the image will help. Another method is to use Photoshop to make the image high contrast and black and white.
3.Islands and Bridges
So leave small gaps / bridges to all the white bits. Say you have black around the eyes,
but you want the white bits left. Leave a gap in the black.This will connect it to rest of the face.
This will come naturally after some tries and mistakes.
4. Careful Cutting
Cutting out your stencil design is probably the most fiddly bit. Here are some tips to stay safe:
1) Go slow and cut lightly.

5. Spraying your Stencil
Once you‛re happy with your stencil, it‛s time to spray! Think about the surface /
material you want your image on (t-shirt, bag, wall, poster...).
Spray quickly and evenly from about 15-25cm away, otherwise the paint will drip (unless you want drips).
Wait 30secs until the paints dry and lift off your stencil to see your design.
6. Other things to try...
You can try spraying on different backgrounds, like cloth or tissue. You can make a 2 or 3 colour image with multiple stencils.
What else can you try?
Quick Tip:
Keep your design simple and bold.
Quick Tip:
You can paint gaps in later. Dab with a finger or brush.
Quick Tip:
Put some tape over really deli- cate areas before cutting to make them stronger.
Quick Tip:
Turning the image as you work will ensure smooth cutting and help you get into corners.

Deferred binding is a feature of the GWT compiler that works by generating many versions of code at compile time, only one of which needs to be loaded by a particular client during bootstrapping at runtime. Each version is generated on a per browser basis, along with any other axis that your application defines or uses. For example, if you were to internationalize your application using GWT's Internationalization module, the GWT compiler would generate various versions of your application per browser environment, such as "Firefox in English", "Firefox in French", "Internet Explorer in English", etc... As a result, the deployed JavaScript code is compact and quicker to download than hand coded JavaScript, containing only the code and resources it needs for a particular browser environment.
Deferred Binding is a technique used by the GWT compiler to create and select a specific implementation of a class based on a set of parameters. In essence, deferred binding is the Google Web Toolkit answer to Java reflection. It allows the GWT developer to produce several variations of their applications custom to each browser environment and have only one of them actually downloaded and executed in the browser.
Deferred binding has several benefits:
Some parts of the toolkit make implicit use of deferred binding, that is, they use the technique as a part of their implementation, but it is not visible to the user of the API. For example, many widgets and panels as well as the DOM class use this technique to implement browser specific logic. Other GWT features require the API user to explicity invoke deferred binding by designing classes that follow specific rules and instantiating instances of the classes with GWT.create(Class), including GWT RPC and I18N.
As a user of the Google Web Toolkit, you may never need to create a new interface that uses deferred binding. If you follow the instructions in the guide for creating internationalized applications or GWT RPC calls you will be using deferred binding, but you will not have to actually write any browser dependent or locale dependent code.
The rest of the deferred binding section describes how to create new rules and classes using deferred binding. If you are new to the toolkit or only intend to use pre-packaged widgets, you will probably want to skip on to the next topic. If you are interested in programming entirely new widgets from the ground up or other functionality that requires cross-browser dependent code, the next sections should be of interest.
There are two ways in which types can be replaced via deferred binding:
The deferred binding mechanism is completely configurable and does not require editing the GWT distributed source code. Deferred binding is configured through the <replace-with> and <generate-with> elements in the module XML files. The deferred binding rules are pulled into the module build through <inherits> elements.
For example, the following configuration invokes deferred binding for the PopupPanel widget:
Inside the PopupPanel module XML file, there happens to be some rules defined for deferred binding. In this case, we're using a replacement rule.
The first type of deferred binding uses replacement. Replacement means overriding the implementation of one java class with another that is determined at compile time. For example, this technique is used to conditionalize the implementation of some widgets, such as the PopupPanel. The use of <inherits> for the PopupPanel class is shown in the previous section describing the deferred binding rules. The actual replacement rules are specified in Popup.gwt.xml, as shown below:
<module>   <replace-with class="com.google.gwt.user.client.ui.impl.PopupImpl"> <when-type-is class="com.google.gwt.user.client.ui.impl.PopupImpl"/> </replace-with>  <replace-with class="com.google.gwt.user.client.ui.impl.PopupImplMozilla"> <when-type-is class="com.google.gwt.user.client.ui.impl.PopupImpl" /> <any> <when-property-is name="user.agent" value="gecko"/> <when-property-is name="user.agent" value="gecko1_8" /> </any> </replace-with>  <replace-with class="com.google.gwt.user.client.ui.impl.PopupImplIE6"> <when-type-is class="com.google.gwt.user.client.ui.impl.PopupImpl"/> <when-property-is name="user.agent" value="ie6" /> </replace-with> </module>
These directives tell the GWT compiler to swap out the PoupImpl class code with different class implementations according to the the user.agent property. The Popup.gwt.xml file specifies a default implementation for the PopupImpl class, an overide for the Mozilla browser (PopupImplMozilla is substituted for PopupImpl), and an override for Internet Explorer version 6 (PopupImplIE6 is substituted for PopupImpl). Note that PopupImpl class or its derived classes cannot be instantiated directly. Instead, the PopupPanel class is used and the GWT.create(Class) technique is used under the hood to instruct the compiler to use deferred binding.
To see how this is used when designing a widget, we will examine the case of the PopupPanel widget further. The PopupPanel class implements the user visible API and contains logic that is common to all browsers. It also instantiates the proper implementation specific logic using the GWT.create(Class) as follows:
private static final PopupImpl impl = GWT.create(PopupImpl.class);
The two classes PopupImplMozilla and PopupImplIE6 extend the PopupImpl class and override some PopupImpl's methods to implement browser specific behavior.
Then, when the PopupPanel class needs to switch to some browser dependent code, it accesses a member function inside the PopupImpl class:
public void setVisible(boolean visible) { // ... common code for all implementations of PopupPanel ... // If the PopupImpl creates an iframe shim, it's also necessary to hide it // as well. impl.setVisible(getElement(), visible); }
The default implementation of PopupImpl.setVisible() is empty, but PopupImplIE6 has some special logic implemented as a JSNI method:
public native void setVisible(Element popup, boolean visible) /*-{ if (popup.__frame) { popup.__frame.style.visibility = visible ? 'visible' : 'hidden'; } }-*/;{
After the GWT compiler runs, it prunes out any unused code. If your application references the PopupPanel class, the compiler will create a separate JavaScript output file for each browser, each containing only one of the implementations: PopupImpl, PopupImplIE6 or PopupImplMozilla. This means that each browser only downloads the implementation it needs, thus reducing the size of the output JavaScript code and minimizing the time needed to download your application from the server.
The second technique for deferred binding consists of using generators. Generators are classes that are invoked by the GWT compiler to generate a Java implementation of a class during compilation. When compiling for production mode, this generated implementation is directly translated to one of the versions of your application in JavaScript code that a client will download based on its browser environment.
The following is an example of how a deferred binding generator is specified to the compiler in the module XML file hierarchy for the RemoteService class - used for GWT-RPC:
The XML element <generate-with> tells the compiler to use a Generator class. Here are the contents of the RemoteService.gwt.xml file relevant to deferred binding:
<module>   <set-property name="gwt.suppressNonStaticFinalFieldWarnings" value="false" /> <generate-with class="com.google.gwt.user.rebind.rpc.ServiceInterfaceProxyGenerator"> <when-type-assignable class="com.google.gwt.user.client.rpc.RemoteService" /> </generate-with> </module>
These directives instruct the GWT compiler to invoke methods in a Generator subclass (ServiceInterfaceProxyGenerator) in order to generate special code when the deferred binding mechanism GWT.create() is encountered while compiling. In this case, if the GWT.create() call references an instance of RemoteService or one of its subclasses, the ServiceInterfaceProxyGenerator's generate()` method will be invoked.
Defining a subclass of the Generator class is much like defining a plug-in to the GWT compiler. The Generator gets called to generate a Java class definition before the Java to JavaScript conversion occurs. The implementation consists of one method that must output Java code to a file and return the name of the generated class as a string.
The following code shows the Generator that is responsible for deferred binding of a RemoteService interface:
/** * Generator for producing the asynchronous version of a * {@link com.google.gwt.user.client.rpc.RemoteService RemoteService} interface. */ public class ServiceInterfaceProxyGenerator extends Generator { /** * Generate a default constructible subclass of the requested type. The * generator throws UnableToCompleteException if for any reason * it cannot provide a substitute class * * @return the name of a subclass to substitute for the requested class, or * return null to cause the requested type itself to be * used * */ public String generate(TreeLogger logger, GeneratorContext ctx, String requestedClass) throws UnableToCompleteException { TypeOracle typeOracle = ctx.getTypeOracle(); assert (typeOracle != null); JClassType remoteService = typeOracle.findType(requestedClass); if (remoteService == null) { logger.log(TreeLogger.ERROR, "Unable to find metadata for type '" + requestedClass + "'", null); throw new UnableToCompleteException(); } if (remoteService.isInterface() == null) { logger.log(TreeLogger.ERROR, remoteService.getQualifiedSourceName() + " is not an interface", null); throw new UnableToCompleteException(); } ProxyCreator proxyCreator = new ProxyCreator(remoteService); TreeLogger proxyLogger = logger.branch(TreeLogger.DEBUG, "Generating client proxy for remote service interface '" + remoteService.getQualifiedSourceName() + "'", null); return proxyCreator.create(proxyLogger, ctx); } }
The typeOracle is an object that contains information about the Java code that has already been parsed that the generator may need to consult. In this case, the generate() method checks it arguments and the passes off the bulk of the work to another class (ProxyCreator).

The TiTouchDB module wraps the iCarousel library written by Nick Lockwood and provides a customizable, data-driven 3D carousel view for Titanium apps.
TiCarousel is currently only available for iOS.
The reference section follows these conventions:
code font
refer to module objects. For example, database is a generic term
but database
refers to a TiCarousel object.To access this module from JavaScript, you would do the following:
var TiCarousel = require("com.obscure.ticarousel");
The TiCarousel variable is a reference to the Module object. You can create new carousel
views by calling TiCarousel.createCarouselView()
with the appropriate options listed below.
Create a simple carousel:
var itemViews = [
Ti.UI.createView({ height: 60, width: 60, backgroundColor: 'blue' }),
Ti.UI.createView({ height: 60, width: 60, backgroundColor: 'yellow' }),
Ti.UI.createView({ height: 60, width: 60, backgroundColor: 'red' }),
Ti.UI.createView({ height: 60, width: 60, backgroundColor: 'green' }),
Ti.UI.createView({ height: 60, width: 60, backgroundColor: 'gray' }),
];
var carousel = TiCarousel.createCarouselView({
carouselType: TiCarousel.CAROUSEL_TYPE_LINEAR,
width: Ti.UI.FILL,
height: 200,
itemWidth: 68,
numberOfVisibleItems: 5,
views: itemViews
});
win.add(carousel);
createCarouselView([Dictionary
Creates and returns an instance of a CarouselView.
parameters
: [DictionaryProperties to set on a new object, including any defined by CarouselView except those marked not-creation or read-only.
indexOfItemView(Ti.UI.View view) : Number
Returns the index of the provided item view in the carousel. This method only works for item views that are visible; if the specified view is not visible, the method returns null.
indexOfItemViewOrSubview(Ti.UI.View view) : Number
Returns the index of the provided item view or the item view containing the provided view in the carousel. If the item view is not visible, returns null.
insertItemAtIndex(Number index, [Boolean animated])
Inserts a new item into the carousel. The new item must be in the views
array prior
to calling this method.
itemViewAtIndex(Number index) : Ti.UI.View
Returns the visible item view with the provided index. This method returns null if the view at the specified index is not visible.
offsetForItemAtIndex(Number index) : Number
Returns the positive or negative offset of the specified item index in multiples of
itemWidth
from the center position.
reloadData()
Reload all carousel items from the view array. This function must be called
if the carousel needs to be refreshed due to changes to properties or the underlying
data. Properties and methods that require a call to reloadData()
will indicate
that in their documentation.
reloadItemAtIndex(Number index, [Boolean animated])
Reload the item view at the specified index. If animated
is true, the carousel will
cross-fade from the old item to the new item.
removeItemAtIndex(Number index)
Remove the item at the specified index from the carousel. This does not remove the
item from the underlying view array, so a call to reloadData()
will restore the view
to the carousel.
scrollByNumberOfItems(Number count, Number duration)
Scroll the carousel by a fixed distance.
count
: Number, the number of items to scroll. Can be positive or negative.duration
: Number, the duration of the scroll animation in milliseconds.scrollToIndex(Number index, [Dictionary options])
Centers the carousel on the specified item. For wrapped carousels, the view will use the shortest route to scroll if the scroll is animated. To control the direction of the scroll or to scroll more than one full revolution, use scrollByNumberOfItems().
index
: NumberThe index of the item to center in the carousel.
options
: [Dictionary]Dictionary with the following scroll options:
animated
: Boolean, default true.duration
: Number, the duration of the scroll animation in milliseconds.bounceDistance : Number, read/write
The maximum distance the carousel will bounce when it overshoots either end, measured
in multiples of itemWidth
. This property only affects carousels which have the wrap
property set to false.
bounces : Boolean, read/write
If true, the carousel will bounce past the end and return. This only affects carousels
which have the wrap
property set to false.
centerItemWhenSelected : Boolean, read/write
If set to true, a tap on an item that is not currently centered will cause the carousel to scroll that item to the center. Default is true.
clipsToBounds : Boolean, read/write
If set to true, the carousel will not display items that fall outside of its own boundaries. Default is false.
contentOffset : Dictionary, read/write
Adjusts the center of the carousel without changing the perspective. This has the effect of moving the carousel without changing the viewpoint. The dictionary should contain the following values:
x
the x offset of the center of the carousel, default 0.0y
the y offset of the center of the carousel, default 0.0currentItemIndex : Number, read-only
The index of the currently-centered item in the carousel.
currentItemView : Ti.UI.View, read-only
The view that is currently centered in the carousel.
decelerationRate : Number, read/write
The rate at which the carousel decelerates when flicked. Value should be between 0.0 (carousel stops immediately) and 1.0 (carousel continues indefinitely until it reaches the end).
ignorePerpendicularSwipes : Boolean, read/write
If set to true, the carousel will ignore swipe gestures that are perpendicular to the direction of scrolling. This is useful for item views that scroll within the carousel. Default is true.
itemWidth : Number, read-write
The display width of the items in the carousel. If a value is not provided, it is determined
from the width of the first item view in the views
array. To add spacing between carousel
items, set this property to a value greater than your item view width.
numberOfItems : Number, read-only
The number of visible items in the carousel.
perspective : Number, read/write

scrollOffset : Number, read-only
The current offset in pixels of the carousel; can be used to position other screen elements while the carousel is scrolling.
scrollSpeed : Number, read/write
A multiplier for the speed of scrolling when the user flicks the carousel. Default is 1.0.
scrollToItemBoundary : Boolean, read/write
When true, the carousel will automatically scroll to the nearest item boundary. When set to false, the carousel will stop wherever scrolling ends, even if it isn't aligned with an item view.
stopAtItemBoundary : Boolean, read/write
When set to true, the carousel will come to rest at an exact item boundary when scrolled. If
set to false, the carousel will stop scrolling naturally and, if scrollToItemBoundary
is true,
scroll back or forward to the nearest boundary.

object.
vertical : Boolean, read/write
Toggles whether the carousel is displayed horizontally (default) or vertically.
viewpointOffset : Dictionary, read/write
Adjusts the camera viewpoint relative to the carousel items. Where contentOffset
moves
the carousel in space, viewpointOffset
moves the user in space. This has the effect of
changing the perspective of the carousel. The dictionary should contain the following values:
x
the x offset of the center of the viewpoint, default 0.0y
the y offset of the center of the viewpoint, default 0.0Several of the built-in transforms can be customized using the transform options dictionary.
Rotary and cylinder carousels can be adjusted using the arc
and radius
properties.
For these carousel types, arc
controls the curvature of the receding views on either side
of the center and radius
the width of the carousel. Wheel carousels are also customized
with arc
and radius
, though the effect is as if you are looking at a cylinder carousel
from above. CoverFlow and TimeMachine-like carousels can be customized using the tilt
and spacing
properties. Finally, the bump carousel can be customized with the yoffset
and zoffset
properties. The example app contains a screen where you can try out different
values for these properties.
IMPORTANT NOTE
Custom transforms should be considered experimental and are not recommended for production use. Use the transform options to customize an existing carousel type if possible before trying the custom transform feature. If you really, really need a new, unique carousel type, consider using the custom transform feature to prototype it, then request that your transform be added to TiCarousel by filing an issue on Github.
In addition to the standard set of carousel types, TiCarousel lets you create your own custom carousel types. A custom carousel type is created by specifying of a set of 3D transforms to apply to the item views based on their position in the carousel. In addition, can control the transparency of the item view to "fade out" based on the view's position.
The custom transform functions are implemented in your Titanium JavaScript file. To use a custom
carousel type, create a new carousel object with a carouselType
property set to
CAROUSEL_TYPE_CUSTOM
:
var carousel = TiCarousel.createCarouselView({
carouselType: TiCarousel.CAROUSEL_TYPE_CUSTOM,
width: Ti.UI.FILL,
height: 200,
itemWidth: 68,
numberOfVisibleItems: 5,
});
Next, create a function that returns one or more transformation descriptors. A transformation
descriptor is a JavaScript object with a type
property containing the name of the transform and
a values
property containing an array of numbers whose meaning depends on the transform type.
The following descriptor types are currently supported:
For example, the Linear carousel type would be implemented as follows:
var itemWidth = carousel.itemWidth;
function transform(offset) {
return [
{ type: 'translate', values: [ offset * itemWidth, 0, 0 ] }
];
}
carousel.itemTransformForOffset = transform;
The transform function receives a parameter named offset
which is the current positive or negative
offset of the view from the center of the carousel.
Transform functions run in an isolated JavaScript context! This means that you cannot reference
the Titanium API or any objects that were created in your application's context. Primitive values
are fine, however, which is why we are setting a primitive named itemWidth
in the example
above.
If you want to change the alpha transparency of the item view based on the offset, create a function that returns a value between 0.0 and 1.0 for each item based on offset. Here's an alpha function that fades views which are more than one unit away from center to 60% opacity:
function alpha(offset) {
var absoffset = Math.abs(offset);
return absoffset < 1.0 ? (1.0 - 0.4 * absoffset) : 0.6;
}
carousel.itemAlphaForOffset = alpha;
Important Note
Custom transform callbacks are expensive and are not recommended for very large carousels. If you have a transform type that you would like to have implemented in native code, please file an issue describing the transform or, better yet, fork the code and send a pull request.

Once when I was about 19 I happen to come across a substance known as 2-cb. I knew it was a designer drug that shulgin invented. I've always been very curious about hallucinogens so I decided I really wanted to try it. The reason I'm writing this now is because I just recently came across some DOB and I did a little research and learned it is very similar in effect except for time span.
At this point in my life I was addicted to heroin. I was attending the local methadone clinic to get off of it. That was a bad idea, I was just switching addictions. Thats a different story. I was also dealing with my fiance' running away for a week to get high. She had just come back to make ammends. I thought I was okay.
I purchased what I was told 2 doses. It was liquid in a shot glass. I put it in my cubbord for 2 days. It turned to a crystal in that period of time. I didn't know if it was going to work or not. Well Danielle (my fiance') went to work and I decided I would trip that day. I love day trips. I put some water on it and let it desolve.  It tasted really bad. I then bought some pot from my downstairs neighbor. He came up and smoked a blunt with me. Keep in mind this man is about a 35 year old black man with a family and good job. Christian man as well. Well when we got done I could tell I felt something different so I told him I was going to take a shower so he would leave.
This is when things got started. I noticed a change in my visual perception. It somewhat reminded me of lsd. Walls breathing, carpet forming patterns, tracers, and colors. I was somewhat excited. I wanted to figure out what I was going to do. I decided I'd go for a walk. As soon as I walked outside everything seemed so big and ...... not really scary but just to much. So I went back inside my appartment.
I was very indecissive. I decided I would put on a movie. I wanted a light hearted movie so I chose Can't Hardly Wait. Well this movie is somewhat of a romance/comedy. When I saw how this guy felt about the girl in the movie it made me think of Danielle. I started getting really depressed thinking, 'why would she want me?' 'I'm a junkie, that doesn't treat her right' Well in reality thats the same thing she was but I couldn't see that.
The trip was starting to get pretty hard at this point. All I could think about was Danielle. I was in a serious state of depression. It was horrible. The visuals were getting extremely strong. I liked that. It was the only entertainment I had because I wasn't enjoying my state of mind. The only thing about it was that they would come and go. One minute everything was moving and changing colors, then next It was bairly breathing. Tracers were the only steady part of visuals.
I then decided I would drive somewhere to get my mind off of everything. (I know driving while tripping is a bad idea but I was not known for my decision making skills.) I went downstairs to my car.
[Erowid Note: Driving while intoxicated or tripping is dangerous and irresponsible because it endangers other people. Don't do it!]
Everything was still so big and somewhat scary at this point but, I was going to make myself. I got into my car and all of a sudden I got VERY clostraphobic. It was scary. I then went back upstairs to my appartment. I don't think I've ever been as indecissive/depressed. At this point I decided I would smoke some pot to try and chill out. It did not help at all. I closed my eyes and LOVED the closed eye visuals more than the oev's. Which is strange to me. My biggest appeal to hallucinogens is seeing my world completely different than normal. I then realized at the center of this long tunnel of colors was Danielle...kissing the drug dealer she ran off with. I got up and started crying. Loud depressing crying. My neighbor knocked on my door to see if I was okay. I told him I was fine and to please leave me alone.
I had no idea how long I had been tripping except that it was longer than 2 hours because I watched that movie. I realized I wanted to come down. I started praying out loud for God to release me from this prison of depression I no doubt got myself into. It was terrifying. After that I realized I am going to end this the only way I know how. Taking more drugs. I called around looking for xanax. No one would sale me any because the week danielle was gone I probably took about 50 xanax over 5 days to try and forget about her. There was clearly a problem there. I knew I would then have to get some heroin.
I then drove (crying the entire way) to my smack dealers house. When I got there the visuals were so strong that I couldn't even tell who Ted was in this room of junkies I was in. I was crying and begging for ted to sell me some dope. Everyone thought I was withdrawing, but I told them that I had taken the 2-cb and wanted to end my sadness. They all decided they wanted some. I could bairly comprehend why these people saw how terrible I felt yet they still wanted to do it.  I went home to do it because I don't like hanging out in junkie houses, especially not then.
I got home and only had one needle because I had been off of H for a couple of months at this point, just doing methadone. I sat and tried to rig the shot. It was so hard to see through the tears and I was shaking. The candle flame seemed to keep jumping around and growing. It was terrifying but I knew once I had that sweet brown powder in my vein I would be okay. I finally got a big shot rigged. I put it in my arm and couldn't find a vein. I don't know if it was because my arm appeared to be changing color and moving or if it was because my vein was so tore up. I had blood running all over my arm. The next thing I know is I hear a knock on the door. I freaked out. I looked out the hole and realized it was Danielle coming home from work. Had I been tripping 6 hours already? I then realized the visuals weren't as strong.
I told her to wait a minute and then hid my dope and rigging material under the couch. She came in and saw I was crying. She said 'whats wrong bae' I told her I had been tripping and thinking about how she was going to leave me again.  She said as long as we both try to stay clean that she would be with me. I realized my abillity to hold conversation was so bad that trying to lie about the H would be impossible. I told her I wanted to feel better so I went and got the H. I told her I couldn't get it to work. She comforted me again and told me she understood.  She helped me wash it off.
I then enjoyed the rest of my afternoon/evening with her in my arms as I came back down to baseline. She stayed with me untill 8 months later when I decided I would go to treatment. Halfway through she left me for a drug dealer again. I then thought about how while I was tripping God was trying to tell me eventually she will leave me again. I don't know, but I do know that trip although not to terribly strong visually(compared to alot of GOOD lsd) was the most terrifying trip emotionally I have ever had. I've tripped alot too.
I got off all the drugs. Every now and then I will trip acid again, but other than that I just drink now. Needless to say I probably will not do the DOB. That morning I trully thought everything in my life was okay untill I took the 2-cb. I feel stable right now but I'm afraid something deep down would get drawn up. That trip only lasted 6 hours. I don't think I could take 18 hours of that.

hashtable_for_each(fn, ht)
For each entry in the hash table ht
, call the function fn
by passing it the key
and value as arguments. The order in which keys and values are visited is unspecified.
Return void
.
While a call to hashtable_for_each
is being performed on ht
, it is an error to call any of the following
procedures on ht
: hashtable_at
,
hashtable_set
, hashtable_for_each
,
hashtable_keys
, hashtable_values
and
hashtable_entries
. It is also an error to compare for equality (directly or indirectly with
member
, assoc
, hashtable_at
,
etc.) an object that contains ht
. All these functions may cause the hash table to be reordered and resized.
This restriction allows a more efficient iteration over the key/value bindings.
let h = make_eq_hashtable()
hashtable_set(h, 'name, "nemo")
hashtable_set(h, 'age, 1)
hashtable_for_each(^(k, v) println(k, ": ", v), h)
//> name: nemo
age: 1


Gaussian implements the mathematical model |R*x|^2 = |y|^2 with R'*R=inv(Sigma) where y = whiten(x) = R*x x = unwhiten(x) = inv(R)*y as indeed |y|^2 = y'*y = x'*R'*R*x Various derived classes are available that are more efficient.
The named constructors return a shared_ptr because, when the smart flag is true, the underlying object might be a derived class such as Diagonal.

class[#Std.Expi.context]
t :object
..end
Expression interpreter.
Expi is a base class for all other interpreters (see Std.bili
and Std.biri
, that do all the hard work. Expi recognizes a
language defined by exp
type. It evaluates arbitrary
expressions under provided context.
To create new interpreter use operator new
:
let expi = new expi;; val expi : _#Expi.context expi = <obj>
Note: The type _#Expi.context
is weakly polymorphic subtype of
Expi.context
1
. Basically, this means, that the type is not
generalized and will be instantiated when used and fixed
afterwards.
let r = expi#eval_exp Bil.(int Word.b0 lor int Word.b1);; val r : _#Expi.context Bil.Result.r = <abstr>
The returned value is a state monad parametrized by a subtype
of class Expi.context
. The state monad is a chain of
computations, where each computation is merely a function from
state to a state paired with the result of computation. The
state is accessible inside the computation and can be
changed.
To run the computation use Monad.State.eval
function, that
accepts a state monad and an initial value. Here we can
provide any subtype of Expi.context
as an initial
value. Let start with a Expi.context
as a first approximation:
let x = Monad.State.eval r (new Expi.context);; val x : Bil.result = [0x3] true
The expression evaluates to true
, and the result is tagged
with an identifier [0x3]
. The Exp.context
assigns a unique
identifier for each freshly created result. Tag [0x3]
means
that this was the third value created under provided context.
If the only thing, that you need is just to evaluate an
expression, then you can just use Exp.eval
function:
Exp.eval Bil.(int Word.b0 lor int Word.b1);; - : Bil.value = true
The main strength of expi
is its extensibility. Let's write
a expression evaluator that will record a trace of evaluation:
class context = object
inherit Expi.context
val events : (exp * Bil.result) list = []
method add_event exp res = {< events = (exp,res) :: events >}
method show_events = List.rev events
end
class ['a] exp_tracer = object
constraint 'a = #context
inherit ['a] expi as super
method! eval_exp e =
let open Monad.State in
super#eval_exp e >>= fun r ->
get () >>= fun ctxt ->
put (ctxt#add_event e r) >>= fun () ->
return r
end;;
Note : We made our exp_tracer
class polymorphic as a
courtesy to our fellow programmer, that may want to reuse it.
We can define it by inheriting from expi
parametrized with
our context type, like this: inherit [context] expi
Also, there is no need to write a constraint
, as it will be
inferred automatically.
Now, let's try to use our tracer. We will use
Monad.State.run
function, that returns both, the evaluated
value and the context. (We can also use Monad.State.exec
, if
we're not interested in value at all):
let expi = new exp_tracer;; val expi : _#context exp_tracer = <obj> # let r = expi#eval_exp Bil.(int Word.b0 lor int Word.b1);; val r : _#context Bil.Result.r = <abstr> # let r,ctxt = Monad.State.run r (new context) ;; val r : Bil.result = [0x3] true val ctxt : context = <obj> ctxt#events;; - : (exp * Bil.result) list = [(false, [0x1] false); (true, [0x2] true); (false | true, [0x3] true)]
1
: The weakness of the type variable is introduced by
a value restriction and can't be relaxed since it is invariant
in state monad.
Bap.Std.Expi.S.Eval.semantics
method empty : Std.Bil.storage
creates an empty storage. If you want to provide your own implementation of storage, then it is definitely the right place.
method lookup : Std.var -> (#Std.Expi.context as 'a) r
a variable is looked up in a context
method update : Std.var -> Std.Bil.result -> 'a u
a variable is bind to a value.
method load : Std.Bil.storage -> Std.addr -> 'a r
a byte is loaded from a given address
method store : Std.Bil.storage -> Std.addr -> Std.word -> 'a r
a byte is stored to a a given address
method type_error : Std.type_error -> 'a r
a given typing error has occured
method division_by_zero : unit -> 'a r
we can't do this!
method undefined_addr : Std.addr -> 'a r
called when storage doesn't contain the addr
method undefined_var : Std.var -> 'a r
called when context doesn't know the variable

Detailed Description
The QTextLine class represents a line of text inside a QTextLayout.
A text line is usually created by QTextLayout::createLine().
After being created, the line can be filled using the setLineWidth() or setNumColumns() functions. A line has a number of attributes including the rectangle it occupies, rect(), its coordinates, x() and y(), its textLength(), width() and naturalTextWidth(), and its ascent() and descent() relative to the text. The position of the cursor in terms of the line is available from cursorToX() and its inverse from xToCursor(). A line can be moved with setPosition().

Member Function Documentation
QTextLine::QTextLine()
Creates an invalid line.
qreal QTextLine::ascent() const
Returns the line's ascent.
See also descent() and height().
qreal QTextLine::cursorToX(int *cursorPos, Edge edge = Leading) const
Converts the cursor position cursorPos to the corresponding x position inside the line, taking account of the edge.
If cursorPos is not a valid cursor position, the nearest valid cursor position will be used instead, and cursorPos will be modified to point to this valid cursor position.
See also xToCursor().
qreal QTextLine::cursorToX(int cursorPos, Edge edge = Leading) const
This is an overloaded function.
qreal QTextLine::descent() const
Returns the line's descent.
See also ascent() and height().
void QTextLine::draw(QPainter *painter, const QPointF &position, const QTextLayout::FormatRange *selection = Q_NULLPTR) const
Draws a line on the given painter at the specified position. The selection is reserved for internal use.
QList<QGlyphRun> QTextLine::glyphRuns(int from = -1, int length = -1) const
Returns the glyph indexes and positions for all glyphs in this QTextLine for characters in the range defined by from and length. The from index is relative to the beginning of the text in the containing QTextLayout, and the range must be within the range of QTextLine as given by functions textStart() and textLength().
If from is negative, it will default to textStart(), and if length is negative it will default to the return value of textLength().
This function was introduced in Qt 5.0.
See also QTextLayout::glyphRuns().
qreal QTextLine::height() const
Returns the line's height. This is equal to ascent() + descent() if leading is not included. If leading is included, this equals to ascent() + descent() + leading().
See also ascent(), descent(), leading(), and setLeadingIncluded().
qreal QTextLine::horizontalAdvance() const
Returns the horizontal advance of the text. The advance of the text is the distance from its position to the next position at which text would naturally be drawn.
By adding the advance to the position of the text line and using this as the position of a second text line, you will be able to position the two lines side-by-side without gaps in-between.
This function was introduced in Qt 4.7.
bool QTextLine::isValid() const
Returns true
if this text line is valid; otherwise returns false
.
qreal QTextLine::leading() const
Returns the line's leading.
This function was introduced in Qt 4.6.
See also ascent(), descent(), and height().
bool QTextLine::leadingIncluded() const
Returns true
if positive leading is included into the line's height; otherwise returns false
.
By default, leading is not included.
This function was introduced in Qt 4.6.
See also setLeadingIncluded().
int QTextLine::lineNumber() const
Returns the position of the line in the text engine.
QRectF QTextLine::naturalTextRect() const
Returns the rectangle covered by the line.
qreal QTextLine::naturalTextWidth() const
Returns the width of the line that is occupied by text. This is always <= to width(), and is the minimum width that could be used by layout() without changing the line break position.
QPointF QTextLine::position() const
Returns the line's position relative to the text layout's position.
See also setPosition().
QRectF QTextLine::rect() const
Returns the line's bounding rectangle.
See also x(), y(), textLength(), and width().
void QTextLine::setLeadingIncluded(bool included)
Includes positive leading into the line's height if included is true; otherwise does not include leading.
By default, leading is not included.
Note that negative leading is ignored, it must be handled in the code using the text lines by letting the lines overlap.
This function was introduced in Qt 4.6.
See also leadingIncluded().
void QTextLine::setLineWidth(qreal width)
Lays out the line with the given width. The line is filled from its starting position with as many characters as will fit into the line. In case the text cannot be split at the end of the line, it will be filled with additional characters to the next whitespace or end of the text.
void QTextLine::setNumColumns(int numColumns)
Lays out the line. The line is filled from its starting position with as many characters as are specified by numColumns. In case the text cannot be split until numColumns characters, the line will be filled with as many characters to the next whitespace or end of the text.
void QTextLine::setNumColumns(int numColumns, qreal alignmentWidth)
Lays out the line. The line is filled from its starting position with as many characters as are specified by numColumns. In case the text cannot be split until numColumns characters, the line will be filled with as many characters to the next whitespace or end of the text. The provided alignmentWidth is used as reference width for alignment.
void QTextLine::setPosition(const QPointF &pos)
Moves the line to position pos.
See also position().
int QTextLine::textLength() const
Returns the length of the text in the line.
See also naturalTextWidth().
int QTextLine::textStart() const
Returns the start of the line from the beginning of the string passed to the QTextLayout.
qreal QTextLine::width() const
Returns the line's width as specified by the layout() function.
See also naturalTextWidth(), x(), y(), textLength(), and rect().
qreal QTextLine::x() const
Returns the line's x position.
See also rect(), y(), textLength(), and width().
int QTextLine::xToCursor(qreal x, CursorPosition cpos = CursorBetweenCharacters) const
Converts the x-coordinate x, to the nearest matching cursor position, depending on the cursor position type, cpos. Note that result cursor position includes possible preedit area text.
See also cursorToX().
qreal QTextLine::y() const
Returns the line's y position.
See also x(), rect(), textLength(), and width().


Electronic Design
This week we have to design an electronic circuit called "hello board" made with the same micro of the lesson 4 but this time we have to add at least a button (input device) and a led (output device).

Because I'm an electronic and robotics engineer I help with those lessons. I explain the basics laws of the electricity, the typical usage and effect of the most used components, the basics of microcontroller and so on.
After we make some experimentations in design the PCB with eagle in free mode (with limitation).
Eagle cad is divided in 3 main pieces:
- schematic
- pcb/board
- libraries
The libraries make possible to make a link between the schematic part and the pcb footprint. It make you able to design in simple way your circuit using the simplicity of the schematic process and keep all the traces up to date in the pcb section, so you don't have to remember the physical connection between component and pins but it is already made in the passage between the 3 sides of the program.
For this exercise, we have a library to download and add to the eagle CAD, in it we found all the component we need, just add them to the schematic and we have the footprint ready in the cad.
HERE you can download the library we used to build the circuit
Schematic part is where you have a "schematic" and easy to read representation of the component where all the pin have a number and a nominal name (usually the name of their function), here you can make all the logical connection between the component and declare the name of the net and data bus.
There are different ways to connect component and wire, the graphical one is to connect with a line the 2 point (red),the other is to add a label and name it the same as the net you want to joint (blue).
There is also a useful thing called Junction who make a point to join 2 line or 2 wire (purple).
When you switch to the pcb design section, all the components are converted in their footprint and physical dimension.The connection are maintained, so it is easy to see where the traces have to be made.
You can set a fixed grid that help the drawings of this traces.
A useful tool to have an idea of where the line can pass, is the auto-route process: this tool launch a script who calculate the possible way of the traces giving you a different level of optimization.
But it’s not so clean so after you have to rewrite this traces and make the correction you need with the tool riprup (to cancel the traces) and wire (to draw the traces).
We have all surface mount component so we only need the top layer, in the pcb section we select only top layer and we export the .png file, monochrome.
Because of the fact, we are using a laser to engrave this pcb we export it in 2000dpi, because we have to modify them after in inkscape to make it vector and usable to the Trotec program.
Where the picture is black is where the copper is eliminated.
We set the dimension of the working area to be the same as the copper board so we can arrange better the displacement.
We have also to add a second layer for the laser cut to performs co2 cut. So we expand the black on the border to make the copper be engraved and removed, and after we draw a vector rectangle on the border of the schematic but inside the black, giving them a red colour (to be used in the Trotec cutting program).
After this, the picture need to be exported in svg file.
Download the PNG file of eagle Export
Download the SVG file modified by inkcape
Download the RAR file of the eagle schematic and board of HELLOBOARD
After some fail pcb engraving, we noticed that the perfect planarity of the pcb engraved is ESSENTIAL because the flexx laser have a too little focus space and a minimum inclination of the board make a fail theprocess of removing al the copper...
For this reason we cut a new plexy support for the board and we also put the number of time the laser have to engrave the board from 7 to 9 to make sure all the copper will be removed.
In my design I add also 2 more led to use all the pin of the attiny44. Unfortunately we run out of component for a mismatch in the order and we can all complete the circuit...
The first circuit doesn't work because of the fact I didn't see some short circuit in the board made by a fail in the laser process ... so I will retry the next week!!!
EDIT
I produce other boards like this and the second have some micro traces of copper done in the process of laser vaporizing, this traces make little short circuit between the traces and some spark comes out of the board (little but visible). For this reason also this board dosn’t work.
I make another try the week after, rising the time the laser raster the circuit to 10, so the copper it better removed. This time I soldered the component and the board work properly.

(CorrectAnswer= 0/0, ErrorScore= 0)
The priority here is not safety but closing the 2-pt. White’s board means that Red can take liberties with the position and spread his builders around.
15/14, 13/9 is fine but the most aggressive moves put a builder on the 6-pt. Those plays are 15/14, 10/6, 10/6, 4/3 and 10/9, 10/6.
15/14, 10/6 wins the day because it keeps double fours as a close-out number and makes double sixes a good number if White enters with a two.
10/6, 4/3 comes second and 15/14, 13/9 is a very close third. The key here is to understand the prime objective of closing the 2-pt.

Let’s try to settle on an estimate for \(n\) and \(\psi\) and by looking for consistent \(D_{ap}\) estimates from the SWV and GC blank datasets with known concentrations. We can extract a \(D_{ap}\) by comparing \(I_{GC}\) to \(I_{SWV}\), but because we know the bulk concentration for this in vitro system we can also estimate \(D_{ap}\) by comparing \(I_{GC}\) to \(C\), or \(I_{SWV}\) to \(C\).
Let’s first read in the processed fast dataset.
df_blank <- read_csv("../data/11_28_18_swvFast_gc_soak_processed.csv")
We’ll select just the subset from SWV electrode 1 and GC electrode 2 (collector). Let’s also transform the added PYO from \(\mu M\) to \(\frac{mol}{cm^3}\).
df_cal <- df_blank %>% filter(electrode_from_swv == "i1" & electrode_from_gc ==
"i2") %>% mutate(C_mol_cm3 = PHZaddedInt * (10^-9))
The data look like this:
ggplot(df_cal, aes(x = signal_from_swv, y = signal_from_gc)) +
geom_point() + geom_smooth(method = "lm")
Recall that for this type of data:
\[D_{ap} = \pi t_p \left( \frac{m A \psi}{S} \right) ^2\]
So, here’s a function that will calculate \(D_{ap}\) from the slope of this data:
dap_from_swvGC <- function(m, t_p = 1/(2 * 300)) {
psi <- 0.7
# psi <- 0.75 A <- 0.013 #cm^2
A <- 0.025 #cm^2
S <- 18.4 #cm
d_ap <- (m * A * psi)^2/(S^2 * pi * t_p)
d_ap
}
And now, we’ll fit a linear model and calculate a \(D_{ap}\).
lm_swvGC <- tidy(lm(signal_from_gc ~ signal_from_swv, data = df_cal),
conf.int = T) %>% filter(term == "signal_from_swv") %>% mutate(dap = dap_from_swvGC(m = estimate)) %>%
mutate(dap_high = dap_from_swvGC(m = conf.high)) %>% mutate(dap_low = dap_from_swvGC(m = conf.low)) %>%
mutate(dataset = "SWVvsGC")
lm_swvGC %>% kable() %>% kable_styling()
| term | estimate | std.error | statistic | p.value | conf.low | conf.high | dap | dap_high | dap_low | dataset |
|---|---|---|---|---|---|---|---|---|---|---|
| signal_from_swv | 0.1990355 | 0.0028369 | 70.15961 | 6.4e-06 | 0.1900072 | 0.2080638 | 6.8e-06 | 7.5e-06 | 6.2e-06 | SWVvsGC |
Ok, seems reasonable, let’s move forward and we’ll compare at the end.
Here’s the data:
ggplot(df_cal, aes(x = C_mol_cm3, y = signal_from_swv)) + geom_point() +
geom_smooth(method = "lm")
For a plot of \(I_{SWV}\) vs. \(C\), the slope can be definited in terms of the parameters for \(I_{SWV}\) other than concentration. This yields an expression for \(D_{ap}\):
\[D_{ap} = \pi t_p \left( \frac{m}{\psi n F A} \right) ^2 \] So we’ll again define the function to calculate it:
dap_from_SWV <- function(m, t_p = 1/(2 * 300)) {
n = 1.8
# n=2
psi <- 0.7
# psi <- 0.75
# A <- 0.013 #cm^2
A <- 0.025 #cm^2
F_C = 96485.332
d_ap <- pi * t_p * (m/(psi * n * F_C * A))^2
d_ap
}
The linear model of this data gives the following:
lm_SWV <- tidy(lm(signal_from_swv ~ C_mol_cm3, data = df_cal),
conf.int = T) %>% filter(term == "C_mol_cm3") %>% mutate(dap = dap_from_SWV(m = estimate)) %>%
mutate(dap_high = dap_from_SWV(m = conf.high)) %>% mutate(dap_low = dap_from_SWV(m = conf.low)) %>%
mutate(dataset = "SWV")
lm_SWV %>% kable() %>% kable_styling()
| term | estimate | std.error | statistic | p.value | conf.low | conf.high | dap | dap_high | dap_low | dataset |
|---|---|---|---|---|---|---|---|---|---|---|
| C_mol_cm3 | 111.2799 | 1.590469 | 69.96673 | 6.4e-06 | 106.2183 | 116.3415 | 7e-06 | 7.7e-06 | 6.4e-06 | SWV |
Also seems reasonable.
Here’s the GC vs. Concentration data:
ggplot(df_cal, aes(x = C_mol_cm3, y = signal_from_gc)) + geom_point() +
geom_smooth(method = "lm")
Again, very linear.
\(I_{GC}\) is simply \(I = nFSDC\), so \(D_{ap}\) is:
\[D_{ap} = \frac{m}{n F S}\]
And here’s our function.
dap_from_GC <- function(m) {
n = 1.8
# n=2
S <- 18.4 #cm
F_C = 96485.332
d_ap <- m/(n * F_C * S)
d_ap
}
The linear model:
lm_GC <- tidy(lm(signal_from_gc ~ C_mol_cm3, data = df_cal),
conf.int = T) %>% filter(term == "C_mol_cm3") %>% mutate(dap = dap_from_GC(m = estimate)) %>%
mutate(dap_high = dap_from_GC(m = conf.high)) %>% mutate(dap_low = dap_from_GC(m = conf.low)) %>%
mutate(dataset = "GC")
lm_GC %>% kable() %>% kable_styling()
| term | estimate | std.error | statistic | p.value | conf.low | conf.high | dap | dap_high | dap_low | dataset |
|---|---|---|---|---|---|---|---|---|---|---|
| C_mol_cm3 | 22.16111 | 0.12625 | 175.5335 | 4e-07 | 21.75932 | 22.56289 | 6.9e-06 | 7.1e-06 | 6.8e-06 | GC |
Now let’s look at the estimates from each subset of the data:
lms <- bind_rows(lm_swvGC, lm_SWV, lm_GC) %>% select(dataset,
term, dap, dap_low, dap_high)
lms %>% kable() %>% kable_styling()
| dataset | term | dap | dap_low | dap_high |
|---|---|---|---|---|
| SWVvsGC | signal_from_swv | 6.8e-06 | 6.2e-06 | 7.5e-06 |
| SWV | C_mol_cm3 | 7.0e-06 | 6.4e-06 | 7.7e-06 |
| GC | C_mol_cm3 | 6.9e-06 | 6.8e-06 | 7.1e-06 |
So, you can see that the estimates actually match very closely!!
Here it is plotted:
ggplot(lms, aes(x = dataset, y = dap)) + geom_pointrange(aes(ymin = dap_low,
ymax = dap_high)) + ylim(0, 1e-05)
So, you can see that the estimates correspond very nicely when we use these parameters. Realizing that these estimates should match led me to look for a better estimate of \(\psi\) based on our scan parameters and I found this reference, which suggested that for \(n = 2\) and \(E_{swv} = 25mV, \psi = 0.75\) and for \(n = 1.8, \psi = 0.7\). I tested both and the second parameter set yielded good results, and corresponds to the peak splitting we see in CVs (n is not quite 2). Therefore the parameters I would like to proceed with are:
Of course the first thing I did was go back to the aggregate biofilm dataset and use these parameters to recalculate the biofilm values. Interestingly, many of the values lie higher than the blank IDA estimate. I also saw that the slow SWV blank dataset gave a different value, and that confused me. So I wanted to evaluate it here.
Here I import the dataset, and calculate \(D_{ap}\) values from each subset of the data (using \(t_p = \frac{1}{30}\)). I also defined some alternative functions to play around with the parameters, you can ignore those for now. Here I am using the exact same functions from the SWV fast dataset above.

Ok, so obviously the GC is still the same, because we didn’t do anything different. However, The SWV and SWVvsGC estimates of \(D_{ap}\) are now wildly different!? The SWV estimate is too high and the SWV vs. GC estimate is too low. This suggests that \(n\) and \(\psi\) could be too low. I tried changing the values to 2 and 0.75, but the change was minimal. Therefore, I do not know why these estimates are so off, but I would definitely trust the SWV fast datasets more until we understand why.
With psi = 0.75 and n = 2:
With psi = 0.7 and n = 1.8:
And just for clarity, here you can see that the plots are still extremely linear.
p1 <- ggplot(df_slowCal, aes(x = signal_from_swv, y = signal_from_gc)) +
geom_point() + geom_smooth(method = "lm")
p2 <- ggplot(df_slowCal, aes(x = C_mol_cm3, y = signal_from_swv)) +
geom_point() + geom_smooth(method = "lm")
p3 <- ggplot(df_slowCal, aes(x = C_mol_cm3, y = signal_from_gc)) +
geom_point() + geom_smooth(method = "lm")
p1 | p2 | p3
I am glad that I did this, but it is also unsettling that changing the scan rate throws off the estimate drastically even with a blank electrode. For now, let’s move forward with the parameters I used in the SWV fast section above.


Classes are very important in the Ruby language. Most things in Ruby are objects, that is pretty much everything is a collection of variables and a collection of methods that affect those variables. These can be pretty simple, as in the case of an Integer which has one variable (the number itself) and some methods (like #to_s, or even the addition operator, +) or they can more complicated like Arrays and Hashes. Every object has a class, which basically tells the computer what type of object it is, and what variables and methods to expect for the object. Fixnum, Integer, Array and Hash are all classes built into Ruby but you're not just limited to the default classes, you can define your own.
Let's say we wanted to make a class to simulate a deck of cards. Our variables would be the things that make our deck of cards a deck of cards while our methods would be the things that we want to do with out deck. A standard deck of cards has 52 cards, so we probably want to use an array to hold them. That's all we really need but maybe we want to be fancy, so we'll make a couple variables that tell our deck of cards what color, and what design the back of our cards look like.
As for the methods, we're going to want to be able to shuffle our deck and at the very least be able to draw the top card of our deck. There is a lot more we could do with our deck of cards, play solitaire for example, but I'm going to keep it simple and just stick to the above two methods.
Now that we know what we want in our class it would come out looking something like this:
def deck_of_cards
attr_reader :back_color :back_design
def initialize(color, design)
@back_color = color
@back_design = design
@deck = Array.new(52) {|x| x+1}
end
def shuffle
@deck.shuffle!
end
def draw_card
deck.rotate! #This simply puts the top card on the bottom of the deck, its here
#so calling draw_card twice in a row doesn't draw the same card twice
return @deck[0]
end
end
I've made @back_color and @back_design attr_reader variables which allows people to see the color or design of the cardback just by calling the associated methods but not @deck. This is because the color of design of our deck is something we might want the user, or other programs to see. Maybe we want to be able to display our deck to the screen, we'd need to be able to know what the backs look like to do that. @deck we don't want people to be able to see though, otherwise you could figure out the order of the deck, which is something we don't want.

145. Strange People
Time Limit: 1 sec, Memory Limit: 1 MB
Once upon a time in one kingdom lives strange people. In
this kingdom to travel from city to city there was a taxes. But people
don't want to travel cheaper from one place to another. They want to
travel from place to place by K-th simple expensive path betwen this
cites. Your task is to find how much money they must prepare to go from
one given city to another (also given) if they travel using K'th simple
expensive path between these two cites. And you must print that path. (if
there exist many solutions output any of them) It is guarantee that K'th
expensive path between this cites exist. If there is road between city X
and Y than there is road between Y and X. Between two cites exists no more
than 1 road.
4 <= N - number of cites <=
100 M - number od roads 1 <= taxes
bewtween two cites <= 10000 1 <= K - the K'th
expensive path to find <= 500
Input
N M K x y mon |
x y mon | ... | M lines x y
mon | xs xe where xs is start city and xe is end city x
and y is pairs of integer that are numbers of two cites and mon is tax
between this cites
Output
Z dc x1 x2 x3 x4 .. xn where Z is the cost of the
K'th expensive path and x1 x2 ... xn is the path dc is number of cites in
(x1 x2 x3 ... xn)
Sample Input
5 10 3
1 2 6
1 3 13
1 4 18
1 5 35
2 3 14
2 4 34
2 5 17
3 4 22
3 5 15
4 5 34
1 5
Sample Output
35 2
1 5
Some explanations to Sample Test case: This are all
paths beteen 1 and 5 and their costs 1 2 5 -> 23 1 3 5 ->
28 1 2 3 5 -> 35 1 5 -> 35 1 3 2 5 -> 44 1 4 5 ->
52 1 4 3 5 -> 55 1 3 4 5 -> 69 1 4 2 5 -> 69 1 4 3 2
5 -> 71 1 2 4 5 -> 74 1 2 3 4 5 -> 76 1 2 4 3 5 ->
77 1 4 2 3 5 -> 81 1 3 4 2 5 -> 86 1 3 2 4 5 ->
95
if there exist q or more paths with equal cost than if first of
them is K'th expensive path then some of others q - 1 cites is (K + 1)'th
expensive path and so on.. Example in Sample test paths 1 2 3 5 and 1 5
have equal cost so 3'th expensive path is 35 and 3'th expensive path may
be 1 5 or 1 2 3 5 and 4'th expesnive path is 35 and 4'th expensive path
may be 15 or 1 2 3 5 |

So far we have been using classes in ruby to organize and manipulate data using built in or user defined methods. We call the objects instantiated within that class instance objects, and we similarly call the methods we define as instance methods. An instance object of a class contains all the variables and instance methods of the class to which it belongs.
As an example, here is a simple class definition with one instance method.
Class methods may be defined in a very similar sense, but instead of being an instance of the class, class methods are called on the class itself. It's important to remember that Ruby allows this because classes are also objects in Ruby, even though they contain other objects and methods.
To define a class method, we can use a Ruby keyword called self, which simply refers back to the current object. In the example below, self refers back to the class itself. There are other ways to write class methods, but for now let's keep it simple.
So when would I need to use a class method instead of an instance method?
Generally, instance methods are used to do the bulk of the work in classes. For example, if you needed to use a common string method like .length it would only make sense that you would likely call that method on an instance object string of a class rather than the class itself. We can, however, use class methods to gather information about a class itself.
In the example above, the output will simply be the string "Now I'm a class method!" However, using a similar declaration our class method can be more interactive.
Using our Futurama example from last week, let's write some simple class objects for some of the characters in the TV series.
So now we have 3 instance objects Fry, Zoidberg, and Bender, but let's say we wanted a way to determine how many of these character objects we have created and we wanted to print that value to the screen. In this case we are no longer working with one particular instance of the class, but with the class itself. Let's add a class method that counts how many times our Futurama class is instantiated.
First, we have to create a class variable @@count and set it equal to 0. Then we have to change the value of @@count by adding 1 to it each time initialize is called, which happens every time an object of the class is created. Lastly, we have to add a class method that allows access to the value of @@count when called outside the class. We this code is run in command line, 3 is printed as expected, since we have created 3 characters so far.
Coming Soon!
