10.20 Unordered Set Operations—library(sets)
This library module provides operations on sets represented as unordered lists
with no repeated elements.
The ordered representation used in library(ordsets)
is much more
efficient, but these routines were designed before sort/2
entered the language.
Exported predicates:
add_element(
+Element,
+Set1,
-Set2)
-
is true when Set1 and Set2 are sets represented as unordered lists,
and Set2 = Set1 U {Element}. It may only be used to calculate Set2
given Element and Set1.
del_element(
+Element,
+Set1,
-Set2)
-
is true when Set1 and Set2 are sets represented as unordered lists,
and Set2 = Set1 \ {Element}. It may only be used to calculate Set2
given Element and Set1. If Set1 does not contain Element, Set2 will
be identical to Set1 (the old version made a new copy of Set1). If
Set1 is not an unordered set, but contains more than one copy of
Element, only the first will be removed. If you want to delete all
copies of a given element, use
lists:delete/3
. For a
version which fails if Element is not in Set1, use selectchk/3
.
disjoint(
+Set1,
+Set2)
-
is true when the two given sets have no elements in common.
It is the opposite of
intersect/2
. If either of the arguments
is improper, disjoint/2
will fail.
is_set(
+List)
-
is true when List is a proper list that contains no repeated elements.
pairfrom(
?Set,
?Element1,
?Element2,
?Residue)
-
is true when Set is a list, Element1 occurs in list, Element2
occurs in list after Element1, and Residue is everything in Set
bar the two Elements. The point of this thing is to select
pairs of elements from a set without selecting the same pair
twice in different orders.
intersect(
+Set1,
+Set2)
-
is true when the two sets have a member in common. It assumes
that both sets are known, and that you don't care which element
it is that they share.
subset(
+Set1,
+Set2)
-
is true when each member of Set1 occurs in Set2.
It can only be used to test two given sets; it cannot be used
to generate subsets.
set_order(
+Xs,
+Ys,
-R)
-
is true when R is
<
, =
, or >
according as Xs is a subset of Ys,
equivalent to Ys, or a superset of Ys.
seteq(
+Set1,
+Set2)
-
is true when each Set is a subset of the other.
list_to_set(
+List,
-Set)
-
is true when List and Set are lists, and Set has the same elements
as List in the same order, except that it contains no duplicates.
The two are thus equal considered as sets.
power_set(
+Set,
-PowerSet)
-
is true when Set is a list and PowerSet is a list of lists which
represents the power set of the set that Set represents.
intersection(
+Set1,
+Set2,
-Intersection)
-
is true when all three arguments are lists representing sets,
and Intersection contains every element of Set1 which is also
an element of Set2, the order of elements in Intersection
being the same as in Set1. That is, Intersection represents
the intersection of the sets represented by Set1 and Set2.
intersection(
+ListOfSets,
-Intersection)
- is true when Intersection is the intersection of all the sets in
ListOfSets. The order of elements in Intersection is taken from
the first set in ListOfSets. This has been turned inside out to
minimise the storage turnover.
subtract(
+Set1,
+Set2,
-Difference)
-
is like
intersect/3
, but this time it is the elements of Set1 which
are in Set2 that are deleted. Note that duplicated Elements of
Set1 which are not in Set2 are retained in Difference.
symdiff(+
Set1,
+Set2,
-Difference)
-
is true when Difference is the symmetric difference of Set1 and Set2,
that is, if each element of Difference occurs in one of Set1 and Set2 but
not both. The construction method is such that the answer will have
no duplicates even if the Sets do.
setproduct(
+Set1,
+Set2,
-CartesianProduct)
-
is true when Set1 is a set (list) and Set2 is a set (list) and
CartesianProduct is a set of Elt1-Elt2 pairs, with a pair for
for each element Elt1 of Set1 and Elt2 of Set2.
disjoint_union(
+Set1,
+Set2,
-Union)
-
is true when
disjoint(Set1, Set2)
and union(Set1, Set2, Union)
,
that is, Set1 and Set2 have no element in command and Union is
their union.
union(
+Set1,
+Set2,
-Union)
-
is true when
subtract(Set1,Set2,Diff)
and append(Diff,Set2,Union)
,
that is, when Union is the elements of Set1 that do not occur in
Set2, followed by all the elements of Set2.
union(
+Set1,
+Set2,
-Union,
-Difference)
- is true when
union(Set1, Set2, Union)
and subtract(Set1, Set2, Difference)
.
union(
+ListOfSets,
-Union)
- is true when Union is the union of all the sets in ListOfSets.
It has been arranged with storage turnover in mind.

The GpioEnum enum only defines the GPIOs available by default on the Raspberry Pi 2's header. There are others, not defined, which are not exposed on the header and hence cannot be used and still others which are only available by disabling some other device (I2C, SPI, UART etc) and changing the pinmux setting.
The GPIOs are not exposed on the header in any particularly logical order. You must refer to the Raspberry Pi header pinout in order to determine on which pin the GPIO appears. In particular, be aware that because it says GPIO_4 this does not mean it appears on pin 4 on the header. This is almost never the case and, in fact, GPIO_4 actually appears on pin 7 of the header on the Raspberry Pi 2.
The source code below lists the default GPIO values. In general you can assume that, by default, any particular GPIO is available for use on your Raspberry Pi. The RPICSIO library will correctly set these GPIOs to input or output depending on the type of port class you define to operate on it. Having said that, it is possible that the GPIOs could be redirected in the pinmux and hence be unavailable. This would take some custom work with the Device Tree and if you are doing that then you will probably be aware of why the GPIO is unavailable.
So, the upshot here is that any GPIO you see defined here should be available for use on the Raspberry Pi 2 for input or output.
IMPORTANT NOTE: Before creating any RPICSIO Port class you will need to ensure that the RPICSIO Library knows which type of Raspberry Pi you are dealing with. This is done by executing a call (only once is necessary) like the one below somewhere in your code before you create any port.
RPICSIOConfig.Instance.RPIType = RPITypeEnum.RPITYPE_RPI2;
public enum GpioEnum { GPIO_NONE, GPIO_4, GPIO_5, GPIO_6, GPIO_12, GPIO_13, GPIO_16, GPIO_17, GPIO_18, GPIO_19, GPIO_20, GPIO_21, GPIO_22, GPIO_23, GPIO_24, GPIO_25, GPIO_26, GPIO_27 }

Another static site generator?
With the ever growing population of static site generators, all filling a certain need, I've yet to find one that allows the generation of anything but the simplest of blogs.
That's where mynt comes in, being designed to give you all the features of a CMS with none of the often rigid implementations of those features.
If you're looking to get up and running quickly, give the quickstart guide a read. Otherwise, if you're familiar with static site generators in general, the other more reference style doc pages may be a better jumping off point for you. You can also check out what people are making with mynt if you prefer working off of examples as many are open source.
There are two main places to find other people messing around with mynt: GitHub and IRC. Feel free to use whichever you're the most comfortable with. I only ask if you choose IRC and have a question, please give me a bit (more than a few hours) to see it and help you!

--- layout: post title: "Linq to Sql and ASP.NET MVC - DataContext Per Request" postId: 292 ---
This is the first in a series of posts about using Linq to Sql with ASP.NET MVC.
Code for this series is available here.
When using an ORM tool within a web application, it's often common to scope a unit of work to the lifetime of an HTTP Request. If you're using Linq to Sql and ASP.NET MVC, you can achieve this by using an Inversion of Control container in conjunction with an ActionFilter.
For this example, I'm going to be using the StructureMap IoC container alongside a fictional "Blog" database.
Firstly, you'll need to configure StructureMap by calling ObjectFactory.Configure inside your Global.asax passing in a custom Registry instance:
protected void Application_Start() { RegisterRoutes(RouteTable.Routes); ObjectFactory.Configure(cfg => { cfg.AddRegistry(new MyRegistry()); }); }
The code for MyRegistry looks like this:
public class MyRegistry : Registry { public MyRegistry() { For<BlogDataContext>() .HttpContextScoped() .Use(c => new BlogDataContext()); Scan(scan => { scan.AddAllTypesOf<Controller>(); }); } }
Here I'm telling StructureMap to create one instance of my BlogDataContext per HTTP Request as well as registering each Controller instance with the container.
Next, we need to tell MVC to use StructureMap to instantiate our controllers. This can be done by creating a custom ControllerFactory:
public class StructureMapControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { return (IController) ObjectFactory.GetInstance(controllerType); } }
We can then replace the DefaultControllerFactory with the StructureMapControllerFactory in our Application_Start:
protected void Application_Start() { RegisterRoutes(RouteTable.Routes); ObjectFactory.Configure(cfg => { cfg.AddRegistry(new MyRegistry()); }); ControllerBuilder.Current.SetControllerFactory( new StructureMapControllerFactory()); }
Now, if we create a PostController (for creating and editing Posts in our fictional blog), we can now take a BlogDataContext in the constructor (for better testability, you'd probably want to hide the DataContext behind an interface):
public class PostController : Controller { private readonly BlogDataContext context; public PostController(BlogDataContext context) { this.context = context; } public ActionResult Edit(int id) { var post = context.Posts.Single(x => x.Id == id); return View(post); } }
Now, visiting http://mysite/Post/Edit/1 would return a view to display a post with the Id of 1 (assuming the appropriate Post exists in the database).
We can take this a stage further by adding an ActionFilter to our application that will automatically call SubmitChanges on our DataContext at the end of the HTTP Request:
public class AutoCommitAttribute : ActionFilterAttribute { public override void OnActionExecuted(ActionExecutedContext filterContext) { if (filterContext.Controller.ViewData.ModelState.IsValid) { var currentDataContext = ObjectFactory.GetInstance<BlogDataContext>(); using (var transaction = new TransactionScope()) { currentDataContext.SubmitChanges(); transaction.Complete(); } } } }
Here we call into StructureMap to retrieve our current DataContext and commit any changes back to the database inside a transaction. Note that this will only happen if the ModelState is valid (ie there are no validation errors).
Another thing to keep in mind that using an IoC container as a Service Locator (as we're doing in this filter) is generally considered bad practice. There are ways around this but these are outside the scope of this post.
Now, whenever we make a change to one of our entities the change will automatically be committed to the database provided the action is decorated with the AutoCommit attribute:
[AcceptVerbs(HttpVerbs.Post), AutoCommit] public ActionResult Create(Post post) { context.Posts.InsertOnSubmit(post); return RedirectToAction("Index"); }

Frequenty Asked Questions:What is this site?Please refer to the about page. What do the arrows represent?The arrows are used for voting, the up arrow being a vote for and the down arrow being against. Once voted the post's score will change according to which arrow was pressed and then either be seen and celebrated by everybody or doomed to the pits of obscurity. What does the important button do?Importance is an alternative to voting up. The difference here is that giving importance gives the post a much greater boost in terms of how long it stays in it's highest position and it also allows a post to move the ranks a lot more quickly. This may sound all great and all however the user that gives importance to a post does so at the expense of 5 of his own attained points. This should prevent a mass of people from giving importance to a post due to bias or political beliefs. So when should I give importance?I guess if you feel that a certain post or topic is not getting enough attention, that's all. What exactly is a topic?A topic is a like a hashtag on sites like Twitter. It's primarily used to quickly describe the general subject area a post is about. For example say a post is made about a robbery in London the topic given would be called London and maybe another one called robbery. And this event thing?An event is the specific event a post is about. This is used so that a number of posts about the same topic, from different sources, can be easily ordered and seen by users. For example, a post about a car crash in New York would have "Car crash in New York" as it's event name, whilst the topic tag would probably be called New York. |

Republished from Opperator blog
When building a product for your audience, you need to empathize with their pains and problems. It's one thing to imagine yourself in their proverbial shoes, but it's much more effective to just wear the same damn shoes. It means using your own product while you're building your product. Startup slang commonly refers to this as "dog-fooding", but I dislike this term because it evokes images of being forced fed something you don't want.
While it's important to focus on relieving your customers' pain, it's equally important to optimize your own happiness along the way. Not only will you enjoy your work more, your code will be "happier" as well. Allow me to explain what happy code looks like.
When Michael and I started Opperator, we aligned ourselves with our customers.  When life is awesome for our customers, life is also awesome for us. It's a very simple formula to balance: remove sucky things, and increase awesome things. Simple as this sounds, many entrepreneurs only tackle the former half of the formula. For any startup, there are many things that happen behind the scenes that your customers don't see. Things like code smells, technical debt, and shoddy documentation. But just because your customers don't see these things, doesn't mean that you don't.
We execute quickly on Opperator, but we also take the time to step back and holistically evaluate our product.
These aren't things that your customer will see. But over time, these things will add up. If you're not happy with working on your product, then your efforts will be forced, and the results will reflect this. Taking a small slice of time to take care of any of these points will yield long term results for your business and for yourself.

BMW, Daimler, Volkswagen fined for steel cartel
The German automakers and steel makers have admitted to fixing prices over a 12-year period.
by Derek Fung- shares
Germany's three major automakers, the BMW Group, Daimler (parent of Mercedes-Benz) and the Volkswagen Group, have been fined a total of €100 million ($163 million) for forming a cartel to buy certain steel products.
The Bundeskartellamt, Germany's competition commission, says the three car companies met twice a year with steel makers between 2004 and 2013 to set uniform surcharges for the long steel they purchased. Illegally set prices were in use until 2016.
The long steel was use primarily for crankshafts, gears, steering rods and handle bars. According to the commission, long steel products account for under one per cent of the cost of a car.
BMW has confirmed it will pay a penalty of €28 million ($45.6 million), Daimler said its fine is €23.5 million ($38.2 million), and Volkswagen will cough up €48.7 million ($79.2 million).
All three car makers have "accepted the facts established" by the commission, and their co-operation has been factored into their penalties.
The competition commission is continuing to investigate price fixing within the German steel industry.
Meanwhile, the three German automakers are still under investigation by the European Commission for allegedly conspiring to not compete on emissions reduction technology.

EPL: What Pep Guardiola Told Players After Man United Defeat
by Emmanuel EgobiambuManchester City coach Pep Guardiola told his players to take the positives following their 2-1 loss to Manchester United in a Premier League tie, Saturday.
Concise News understands that the defeat left City 14 points adrift of league leaders Liverpool.
And following the loss to United, the club’s midfielder Rodri, said the Spaniard did not blast the players.
“The manager always takes the good points,” Rodri told Metro UK. “He tried to lift our heads up. It is a tough moment for the team, but we have to keep fighting.
“We have other cups, other goals which are interesting and very good, so we need to keep fighting and of course recover people because we have lots of problems with injuries – it’s been tough at the beginning of the season.”
Manchester City will take on Arsenal in their Premier League showdown at the Emirates Stadium on Sunday.

GREAT BALLS OF FIRE A film review by Randy Parker Copyright 1996 Randy Parker
RATING: **1/2 (out of ****)
(Review written in 1989)
The story of Jerry Lee Lewis is ripe with dramatic possibilities. GREAT BALLS OF FIRE chooses not to explore them. The movie could have been a dramatic psychological character study, or it might have been a backstage look at the music industry or at the history of rock 'n roll. Instead director/co-writer Jim McBride has taken the road of TUCKER and made a movie that is all flash and no substance.
The movie chronicles the early days of Lewis' career: his rise to rock stardom, his controversial marriage, and his violent tantrums and alcohol abuse. In telling the story, McBride shows little subtlety or nuance; he paints everything with wide brush strokes. The entire movie is larger than life, including Dennis Quaid's performance as the "Killer."
Quaid displays charisma, flamboyance, and down-home charm in the role. His enthusiasm and cockiness are well suited to conveying the electricity of Jerry Lee's music. Thanks to Quaid's hyper-manic, physical performance and strong stage presence, the concert scenes in GREAT BALLS OF FIRE are exhilarating, even incendiary. Before one concert, for example, Lewis is beside himself because he has to open for Little Richard. He thinks he should get to headline the concert since "Great Balls of Fire" is the number one song in the country. Fueled by his anger, Lewis takes the stage and delivers a rousing performance of "Great Balls." He whips the crowd into a frenzy by setting his piano afire at the song's climax. As Lewis leaves the stage, he boasts to Little Richard, "Follow that!" Quaid has succeeded in capturing the essence of Jerry Lee, the musician and performer.
On the down-side, Jerry Lee, the person, is nowhere to be found in GREAT BALLS OF FIRE. Neither Quaid's exaggerated one-note performance nor McBride's script lets us into Lewis' head. Just what makes this man tick, besides music and 13 year old girls? GREAT BALLS OF FIRE doesn't provide any answers. The movie is paper thin, altogether lacking complexity. It could learn a few things from SCANDAL, or better yet, LA BAMBA.
GREAT BALLS is so superficial and so light-weight that we can never take it seriously. Consequently, the movie's few attempts at drama fail miserably; they have neither credibility nor impact. LA BAMBA, on the other hand, overcame its cliched rags to riches story to offer some exceptional performances and riveting domestic drama. Esai Morales' performance as Ritchie's jealous and troubled brother haunts me to this day. Lewis' life is at least as rich a source of dramatic material, but GREAT BALLS OF FIRE carefully avoids developing any serious themes which might disrupt its light tone. Sure, the Killer's music is great, but it's his personal problems which make him interesting, troubling, and controversial. Why even bother to make a film of Lewis' life if you're going to ignore the cutting edges which make him an enigma?
Winona Ryder (as Myra Lewis) manages to instill some depth into the shallow story. Ryder is captivating as she portrays the pain, confusion, and excitement of not only marrying a pop idol but doing so at age 13. Whether she's expressing Myra's wholesome innocence, her sexual awakening, or her reckless abandon while spending Lewis' money, Ryder's screen presence is magnetic, drawing us into the character. Her look of fear and bewilderment at her impromptu wedding ceremony is amusing but also compelling. But despite Ryder's efforts, the movie still left me with the feeling that Myra has been shortchanged, her story and situation underdeveloped. GREAT BALL OF FIRE provides no more than a shallow "Classics Illustrated" version of her life-story.
Ultimately, GREAT BALLS OF FIRE isn't especially memorable, but I have to admit that the movie is fun while it lasts. It may be all style and no substance, but what style! The movie is intensely colorful, and it succeeds in recreating the '50s, complete with classic clothes, cars, and cold war. I also appreciated Peter Cook's cameo as a British reporter and Alec Baldwin's performance as Lewis' cousin and boyhood chum, Jimmy Swaggart. Swaggart's self-righteousness, moral indignation, and religious rantings and ravings are deliciously ironic in light of his eventual fall from grace.
Without question, the highlight of the film is Lewis' music, which he re-recorded for the film with Dennis Quaid lip-synching. Lewis is in top form; his passion and talent have not diminished over the years while the technology of recording music has improved dramatically. Consequently, the songs in the movie actually sound better and are more exciting than the originals. I went into GREAT BALLS OF FIRE indifferent to Lewis' music and I came out desperately eager to buy the soundtrack. So even though GREAT BALLS OF FIRE pales in comparison to such fine rock biographies as LA BAMBA and THE BUDDY HOLLY STORY, I have to give the movie credit for getting the music right.

Being nerdy is something between vocation and individual nature. You can be born or you can become one.  If you landed here, we are sure we will awaken the nerdy side we know is in you.
The real nerd is a wonderful creature. There are many chances that he/she accompanied Frodo on his journey to Middle-earth, did magic with Harry Potter, Ron Weasley and Hermione Granger, spent his childhood hurting his mother's feet by disseminating LEGO bricks in his room and, of course, spent nights and days studying Klingon.
If you know what we are talking about (well, at least we know you didn't study Klingon, did you?), this is the right spot for you. We have taken a shorter timeline, composed by four dots, each of them hosting a different nerdy style. We played a bit with Javascript and, therefore, we also got help from few codes we found online. We present here:
So, have a good time and may the Force be with you!

9. Introduction
10. Why Snakemake?
A common pattern in scientific computing involves the execution of many computational or data manipulation tasks. Those tasks are usually coupled, i.e., data produced by of one task are consumed by one or more other tasks. Thus execution of such tasks often requires a non-trivial coordination (orchestration) to satisfy their data dependencies.
Snakemake is a workflow management system that .
 Rules can either use shell commands, plain Python code or external Python or R scripts to create output files from input files. Original Paper
The workflow is implied by dependencies between the rules that arise from one rule needing an output file of another as an input file.
For each rule you need to provide:
- Input : Data files, scripts, executables or any other files.
- Expected output. It’s not required to list all possible outputs. Just those that you want to monitor or that are used by a subsequent step as inputs.
- A command to run to process the input and create the output.
rule myname:
input: ['myinput1', 'myinput2']
output: ['myoutput']
shell: 'Some command to go from in to out'
10.1. Snakemake Advantages:
- Memory: stores the architecture of the work and allows you to rapidly perform a complete or partial analysis.
- Portability: if built in a user-sensitive way, anyone working on the same analysis can obtain every results.
- Modularity: as a rule is only a path between an input and an output, if one method or technique used in the analysis needs to be updated or modified, it can be replaced by a new rule with the same output. It allows a parallel comparison of different techniques in a very simple way.
- Reproducibility: if you’re analysing a data sample collected by the same experiment in different years of exploitation and you plan to analyse data samples not even collected yet, Snakemake is a simple solution to perform the same analysis to different data sets.
- Snakemake workflows can be easily executed on workstations, clusters, the grid, and in the cloud without modification. The job scheduling can be constrained by arbitrary resources like e.g. available CPU cores, memory or GPUs.
- Snakemake can automatically deploy required software dependencies of a workflow using Conda or Singularity.
- Snakemake can use Amazon S3, Google Storage, Dropbox, FTP, WebDAV, SFTP and iRODS to access input or output files and further access input files via HTTP and HTTPS.
11. Why Containers?
A container image is an encapsulated, portable environment that is created to distribute a scientific analysis or a general function. Containers help with reproducibility of such content as they nicely package software and data dependencies, along with libraries that are needed.
- Hubs hosts over 100,000 pre-built, ready-to-use containers
- examples of things you can do with containers:
- Package an analysis pipeline so that it runs on your laptop, in the cloud, and in a high performance computing (HPC) environment to produce the same result.
- Publish a paper and include a link to a container with all of the data and software that you used so that others can easily reproduce your results.
- Install and run an application that requires a complicated stack of dependencies with a few keystrokes.
- Create a pipeline or complex workflow where each individual program is meant to run on a different operating system.

Java Accessibility Guide > Java Accessibility API (JAAPI) Programmer's Guide > Java Accessibility Overview
The Java Accessibility API (JAAPI) is one of the core parts of the Java Foundation Classes (JFC). The JFC are a comprehensive set of graphical user interface components and foundation services designed to simplify deployment of Internet, intranet and desktop applications. The JAAPI makes GUI component information available to assistive technologies, giving users alternative presentation and control of Java applications.
The Java Accessibility Utilities help assistive technologies take advantage of the Java Accessibility API. The Utilities monitor events related to UI components. They also help assistive technologies get additional information about a GUI, such as the current position of the mouse, or the window that currently has focus.
The Java Foundation Classes implement a Pluggable Look and Feel architecture. This architecture allows non-visual manifestations of a user interface to replace or enhance the visual presentation of an application. The expression of the user interface is separated from the underlying structure and data of each individual component. This is accomplished by separating the user interface of the component from its model. The model of a component is the structure which encapsulates the state and information that is presented to the user by the user interface. More information on this architecture can be found in About the JFC and Swing in the Creating a GUI with JFC/Swing trail in the Java Tutorials.

Meshes make up a large part of your 3D worlds. Aside from some Asset store plugins, Unity does not include modelling tools. Unity does however have great interactivity with most 3D modelling packages. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons.
Unity supports importing Meshes from two different types of files:
Unity can import and use both types of files, and each come with their own advantages and disadvantages.
Unity can read .fbx, .dae (Collada), .3ds, .dxf, .obj, and .skp files. Refer to your 3D modeling software documentation for information about exporting 3D files.
Advantages:
Disadvantages:
Unity can import proprietary files from the following DCC software: Max, Maya, Blender, Cinema4D, Modo, Lightwave & Cheetah3D. Files imported this way are converted into .fbx files by Unity during the import process.
Advantages:
Disadvantages:
Note: Assets saved as .ma, .mb, .max, .c4d, or .blend files fail to import unless you have the corresponding DCC software installed in your computer. This means that everybody working on your Unity project must have the correct software installed. For example, if you use Maya to create ExampleModel.mb and copy it into your project, anyone else opening that project also needs to have Maya installed on their computer.
Here are some guidelines for directly supported 3D applications, others can most often export file type listed above.
Unity will attempt to find the textures used by a mesh automatically on import by following a specific search plan. First, the importer will look for a sub-folder called Textures within the same folder as the mesh or in any parent folder. If this fails, an exhaustive search of all textures in the project will be carried out. Although slightly slower, the main disadvantage of the exhaustive search is that there could be two or more textures in the project with the same name. In this case, it is not guaranteed that the right one will be found.
FBX importer options for the model
For each imported material Unity will apply the following rules:-
If material generation is disabled (i.e. Import Materials is unchecked), then it will assign the Default-Diffuse material. If it is enabled then it will do the following:
Unity uses two main types of colliders: Mesh Colliders and Primitive Colliders. Mesh colliders are components that use imported mesh data and can be used for environment collision. When you enable Generate Colliders in the Import Settings, a Mesh collider is automatically added when the mesh is added to the Scene. It will be considered solid as far as the physics system is concerned.
If you are moving the object around (a car for example), you can not use Mesh colliders. Instead, you will have to use Primitive colliders. In this case you should disable the Generate Colliders setting.
Animations are automatically imported from the scene. For more details about animation import options see the section on asset preparation and import in the Mecanim animation system.
If you have a character with a normal map that was generated from a high-polygon version of the model, you should import the game-quality version with a Smoothing angle of 180 degrees. This will prevent odd-looking seams in lighting due to tangent splitting. If the seams are still present with these settings, enable Split tangents across UV seams.
If you are converting a greyscale image into a normal map, you don’t need to worry about this.
Unity has support for BlendShapes (also called morph-targets or vertex level animation). Unity can import BlendShapes from .FBX (BlendShapes and controlling aninimation) and .dae (only BlendShapes) exported 3D files. Unity BlendShapes support vertex level animation on vertices, normals and tangents. Mesh can be affected by skin and BlendShapes at the same time. All meshes imported with BlendShapes will use SkinnedMeshRenderer (no mater if it does have skin or not). BlendShape animation is imported as part of regular animation - it simply animates BlendShape weights on SkinnedMeshRenderer.
There are two ways to import BlendShapes with normals:
If you want tangents on your BlendShapes then set Tangents import mode to Calculate.
This is correct. What you are looking at is the number of vertices/triangles actually being sent to the GPU for rendering. In addition to the case where the material requires them to be sent twice, other things like hard-normals and non-contiguous UVs increase vertex/triangle counts significantly compared to what a modeling app tells you. Triangles need to be contiguous in both 3D and UV space to form a strip, so when you have UV seams, degenerate triangles have to be made to form strips - this bumps up the count.

So, as I’ve mentioned a few times recently, I’ve been working on a logic engine for Ruby, using a Ruby-ish DSL. It’s working quite nicely now, and is able to do the examples that Mauricio so kindly provided, including the Tower of Hanoi solver, and the symbolic differentiator.
The exercise has been fun, as well as very educational. For the curious, you can check it out at http://svn.jamisbuck.org/projects/logic_engine. For now, I’d like to talk a bit about how I implemented the DSL, since that’s probably of more general interest.
First, I “sketched it out”. Not on paper, but in a blank text document. This let me define how I wanted the DSL to look, and also proved as a good thought experiment, letting me try things out in a very low-risk environment.
My first pass, as I blogged about here, used methods on Symbol and String:
1 2 3 4 5 6 |
:X.sibling_of(:Y).if :Z.parent_of(:X).and(:Z.parent_of(:Y)).and(:X.noteq(:Y)) ... "matz".father_of "Ruby" ... result = :X.sibling_of("Sally").solutions result.each { |solution| p solution } |
However, this required the the Symbol and String namespaces to be “polluted” by method_missing hooks and so forth. It also was hard to make that work with multiple knowledgebases in the same program, since the method_missing hook for both String and Symbol would need to know which database the predicate was referencing.
So, that first pass defined a few boundaries for me. I knew that I wanted multiple databases, and that terms needed to be defined within the context of a specific database. My second attempt looked something like this:
1 2 3 4 5 6 7 |
db = Database.new do X.sibling_of(Y).if Z.parent_of(X).and(...).and(...) matz.father_of(ruby) ... end result = db.query { X.sibling_of(sally) } |
Ugh, though. That one required const_missing to be captured, and that can only be captured at the class level, not the object instance level. How would I be able to access the current DB instance inside the const_missing hook? That seemed like it could be tricky, so I tried to work around the need for it. Instead, I considered using conventions like if a method is invoked that starts with an underscore, it is a variable>
1 2 3 4 |
db = Database.new do _X.sibling_of(_Y).if _Z.parent_of(_X).and(...).and(...) ... end |
But that, frankly, made my eyes bleed. I also considered using punctuation, like X!
and Y!
to indicate variables, but that was far too noisy. In the end, I really wanted Ruby constants to indicate variables in the assertions.
Fortunately, it wasn’t so bad to implement. It only required a minor bit of “pollution” in the Module-level const_missing hook, and I tried to minimize the damage there by chaining my handler to the existing one. Then, I made sure to set the current DB instance in a thread-local variable, which I could access from the const_missing hook. (This assumes that a single thread will never be processing more than one database at a time, which is a fair assumption, I think.) You can see my implementation of the const_missing hook here.
So, hurdle hurdled. The next problem was that using and
to create a conjunction was rather ugly, and verbose. Fortunately, Ruby lets you override certain operators, and the ampersand is one of them:
X.sibling_of(Y).if Z.parent_of(X) & Z.parent_of(Y) & X.noteq(Y) |
By the time I got this far, I had actually begun to implement the DSL, so I could see how technically feasible (or infeasible) some of these constructs really were. The first thing I discovered was that there was no way for me to know, within the assertion block, which terms were being added to the database:
1 2 3 4 5 6 7 |
db = Database.new do X.is_parent_of(Y).if X.is_father_of(Y) X.is_parent_of(Y).if X.is_mother_of(Y) jamis.is_father_of(nathaniel) end result = db.query { jamis.is_parent_of(nathaniel) } |
Give the above, I’d have to use some more flags to know whether a statement was created at the “top-level”, so to speak, or whether it was created as a child of another statement…and then I’d have to know whether it was safe to add the statement to the database, since when you query, you don’t want that term added.
The simplest thing to do was to require that something be explitly called to add a new term to the database. Using the unary plus operator was the least verbose way I could think of:
1 2 3 |
db = Database.new do + X.sibling_of(Y).if Z.parent_of(X) & ... end |
The problem, though, is that this causes a compile error! It won’t work without parentheses around the arguments to if
, and that’s ugly. So! Think think think.
I solved the problem by using blocks. Instead of passing the implied terms as parameters to if
, I define them in a block that gets attached to if
:
1 2 3 |
db = Database.new do + X.sibling_of(Y).if { Z.parent_of(X) & ... } end |
I actually think I like that better! It’s clearer what is going on, and opens up some interesting possibilities of multiple statements occuring inside that if block. It also looks more like a control structure, which is a nice side effect.
Under the hood, I’m using the “clean room” DSL technique. The block passed to Database.new
is actually evaluated in the context of a “blank” object, a “clean room”, that just proxies the data back to the database. This way, method missing calls all just happen on the clean room, and I don’t have to worry about the methods on my Database class shadowing the names of atoms and predicates and such.
It’s turned out pretty nicely. The matching and backtracking implementation is certainly not optimized yet, and a LOT of objects get created right now, but it works! Feel free to check it out at check it out at http://svn.jamisbuck.org/projects/logic_engine. I’d love to hear what you think of it, thus far.
