Handles updating the GPU light buffer with current scene's lighting. All light sources are uploaded as instances of the GPULight structures.
Ambient lighting is always passed over in the buffers 0 index, with the number of lights recorded in it's light type property (Buffer[0].parameters.z).
Culling of visible lights is done using simple frustum culling against bounding volumes generated by the light's properties (bounding spheres for point lights).
Directional and ambient lights are not culled as they affect the entire scene by their very definition.
In Direct3D, the light structured buffer is passed over register t8. See LightManager::LightBufferSlot

If you are not familiar with Mercurial or any other revision control system, then see one of the starting tutorials below or Definitive Guide : revision control primer
Open MacHg, then drag and drop a folder onto the left sidebar. If the folder contains an existing Mercurial repository, you have just started managing it with MacHg. If it is not an existing Mercurial repository, you will be given the option to transform the given folder into a Mercurial repository.
In the Files View, select the entire contents of the folder you just added, ie all files and folders in the repository folder. With the files and folders selected, choose the menu Action > "Add Selected Files", to add the selected files to the new MacHg repository. These files are now marked for addition. Now choose the menu Action > "Commit Selected Files..." to commit these changes. In the commit dialog enter an informative message like "initializing my repository with the files that I want."
Now in some external application (eg., xcode, bbedit, etc) make some edits to the files you have just added, and save your edits. Switch back to MacHg. You should see that the files are marked as modified in MacHg. Now select the modified files in MacHg again and choose the menu Action > "Diff Selected Files". After reviewing the differences, save these changes into the Mercurial repository using Action > "Commit Selected Files..."
A server repository is a repository that is resident on a server and not resident on your local machine. Since such a repository is on a server, MacHg can only record a reference to this remote repository. To work with a server repository you must first make a local clone of it on your machine, and then work with this local repository.
To add an example server, choose Repository > "Add Server Repository...". In the ensuing dialog enter http://selenic.com/repo/hello in the Sever URL field, and enter an informative name in the short name field, eg. hellorepo. Click the button "Add Server" to create the bookmark.
Now with the new server bookmark selected in the sidebar, choose Repository > "Clone...". In the clone sheet that has popped up, enter a local path where you are going to clone this server to, together with a new shortname and hit "Clone Repository". This will give you a local clone of the example repository, hello, which is resident on selenic.com (the creators of Mercurial). Then you can modify the files in this repository and commit them. (You can't push changes from your repository to selenic's hello repository because you are not allowed write access to this repository.)
Go to bitbucket and create your own account. You can host a private repository (or public repository) there for free. After experimenting with the functionality, you can upgrade your account for other people on your team to access it, etc. (I have no relation to bitbucket; it's just a neat site if you are using Mercurial. Of course, if your company or team already has a Mercurial host somewhere, then use that...)

Java Swing TutorialJava Swing tutorial is a part of Java Foundation Classes (JFC) that is used to create window-based applications. It is built on the top of AWT (Abstract Windowing Toolkit) API and entirely written in java. Unlike AWT, Java Swing provides platform-independent and lightweight components. The javax.swing package provides classes for java swing API such as JButton, JTextField, JTextArea, JRadioButton, JCheckbox, JMenu, JColorChooser etc. Difference between AWT and SwingThere are many differences between java awt and swing that are given below.
What is JFCThe Java Foundation Classes (JFC) are a set of GUI components which simplify the development of desktop applications. Hierarchy of Java Swing classesThe hierarchy of java swing API is given below. Commonly used Methods of Component classThe methods of Component class are widely used in java swing that are given below.
Java Swing ExamplesThere are two ways to create a frame:
We can write the code of swing inside the main(), constructor or any other method. Simple Java Swing ExampleLet's see a simple swing example where we are creating one button and adding it on the JFrame object inside the main() method. File: FirstSwingExample.java Example of Swing by Association inside constructorWe can also write all the codes of creating JFrame, JButton and method call inside the java constructor. File: Simple.java The setBounds(int xaxis, int yaxis, int width, int height)is used in the above example that sets the position of the button. Simple example of Swing by inheritanceWe can also inherit the JFrame class, so there is no need to create the instance of JFrame class explicitly. File: Simple2.java

Indiana Jones And The Last Crusade A review by Joe Chamberlain
Starring Harrison Ford; Sean Connery; Denholm Elliot; Alison Doody & John Rhys-Davies
How do you make an Indiana Jones film even better? By adding Sean Connery to the cast.  When you add Stephen Speilberg as the director and George Lucas as producer and one of the writers, all the elements are there for a spectacular film experience. Indiana Jones And The Last Crusade does not disappoint on any level. Other than the fact that this has long been reputed to be the last film in the series. One can not be just a little sad that this much talent may never collaborate again to make another one of these films that really represent why people love going to the movies.
This time out, Indiana's (Ford) father, Henry Jones (Connery) is working for a wealthy collector who is financing his life long quest for the Holy Grail. The Nazis, who are also interested in the Grail, are in competition with Jones. (I guess they are still ticked off over that whole Lost Ark thing.) Anyway, Jones goes missing. So son Indiana travels to his fathers last known location, Venice, to try to find out what happened to his father and also see if he can't complete his father's search for the Grail. He travels with longtime friend, Marcus Brody (Denholm Elliot), and the hook up with the elder Jones' assistant, Dr. Elsa Schneider (Alison Doody). Together the three search Venice for clues to the location of the Grail. Jones eventually finds his father who joins the group on the quest for the Grail. As usual, Indiana's adventures are never dull, and this time he has to deal with Nazis, rats and a high speed boat chase on the way to his goal of the Grail.
Indiana Jones And The Last Crusade is very well written and lives up to the first two films. No disappointments here. The film opens with a flashback sequence with Indiana as a boy and explains many of the reasons that Indiana is the man he is. Last Crusade is frequently funny which is a tribute as much to the interaction of the leads as it is to the sharp writing. Harrison Ford and Sean Connery are perfectly cast as the father and son who don't always see eye to eye. Throw in the supporting cast of Denholm Elliot and John Rhys-Davies (Sallah), both returning to their roles from Raiders Of The Lost Ark and there are more than a few light moments intertwined with the seemingly nonstop action.
Like the previous films, Stephen Speilberg gives us a film filled with elaborate stunts and the sort of settings that can only be found in an Indiana Jones movie. There is virtually nothing wrong with this movie from a technical standpoint. Last Crusade has stood up well in the 10 years since it first hit the big screen. It is easily one of the finest action/adventure films ever made. This film also compares very well to the first one, Raiders Of The Lost Ark, which in my opinion, is quite possibly the best film ever made.

Lack of quorum in Parliament, again
by BY AZRIL ANNUARKUALA LUMPUR, Nov 20 — Dewan Rakyat proceedings halted temporarily this morning shortly after sitting as there were insufficient MPs in the House.
Barisan Nasional lawmaker Datuk Abdul Rahman Mohamad (Lipis) raised the matter just before the first question was posed by Tampin (PH) MP Datuk Hasan Baharom during Question Time.
“Yang di Pertua, point of order. There’s not enough quorum in the House,” said Abdul Rahman, catching the attention of Speaker Tan Sri Mohamad Ariff Md Yusof.
Mohamad Ariff began counting how many MPs were in the Lower House and was heard to say that there was only 24 MPs out of 222.
Parliamentary Standing Orders states a minimum of 26 MPs must be in the House.
The Speaker rang the bell for a full minute the second time and several MPs, including Deputy Women, Family and Community Development Minister Hannah Yeoh and Port Dickson MP Datuk Seri Anwar Ibrahim, were seen rushing into the House.
Opposition members including its chief, Bera MP Datuk Seri Ismail Sabri Yaakob, and Parit Sulong MP Datuk Noraini Ahmad was also seen walking around Parliament lobby with an amused look on their face while the bell was being rung.
This is the second time that the number of MPs dropped below quorum since the current third meeting of the second session of the Dewan Rakyat started on October 7. The meeting will last until December 5 this year.
On October 17, Deputy Speaker Nga Kor Ming was forced to ring the bell to get MPs into the house after 4pm.
Back then, Ismail Sabri slammed Pakatan Harapan MPs for not taking the Budget speech seriously, calling it a black day for Parliament.

I've been working on a game side-project for the past year as a fun way to really deep dive into Rust, Amethyst, and different game dev topics such as AI, pathfinding, shaders, etc. The game utilizes an isometric 2.5D view much like SimCity 3000 or Civilization, all from pre-rendered sprites.
As I was working on the map generation and rendering, I found a couple tutorials that went through a basic isometric projection with tiles, but nothing that did it in a way that was generalizable to different view points. Due to the progress I've made thus far with my own game, I decided to do a little writeup (with examples!) to showcase how to go from a grid of points to an isometric projection with different orientations.
Below I have a full example that has been rebuilt in WebGL with different toggles to visualize each step of the transformation.
The code for the example is available here.
From grid to projection
Standard isometric projection has it where if we started with the front face of an object, it would be rotated 45 degrees around the vertical axis and then approximately 35 degrees around the horizontal axis. After these transformations, the objects should look roughly like the different shapes in the image below:
Example of different 3D shapes isometrically projected. Source: Wikipedia
Before we began, some assumptions:
- Tiles will be sprites that are already rendered with the isometric look (à la SimCity 3000).
- The tile grid is represented by a 2D array.
- The camera being used is an orthographic camera.
Assuming the grid to be in Euclidean space where (0,0)
is
at the bottom left, the 2D array of tiles we'll be using in our example
will be represented roughly like the code snippet below:
1 enum Tiles = {
2 GRASS,
3 DIRT
4 };
5
6 let map = [
7 // row 0, col 0; row 0, col 1, etc.
8 [Tiles.GRASS, Tiles.GRASS, ...]
9 ...
10 ];
We can loop through each row and column and render each tile of the grid at
their respective (col, row)
point to get something basic on screen.
1 let geometry = new THREE.PlaneGeometry( 32, 32 );
2
3 let even = new THREE.MeshBasicMaterial({ color: 0xff0000 });
4 let odd = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
5
6 for (let y = 0; y < grid.length; y++) {
7 for (let x = 0; x < grid[y].length; x++) {
8 let tile = new THREE.Mesh(
9 geometry,
10 (x + y) % 2 ? even : odd
11 );
12
13 tile.position.x = x;
14 tile.position.y = y;
15
16 scene.add(tile);
17 }
18 }
When the above code is run (see the repo for the full code snippet), we'll get something that looks roughly like so:
The example grid rendered with 32x32 width tiles at each respective
(col, row)
point
As you can see, without any modification to how we place the tiles everything will overlap with each other. To go from this to the isometric projection we want, we're going to have to apply a series of transforms that will translate, scale, and rotate the tiles to their correct positions.
🤔 What are transforms?
In linear algebra, a transform or transformation matrix refers to a linear mapping between some set of points to another set of points. Typically, these linear transformations can be composed (i.e. applied one after another through multiplication) and inverted (e.g. to map a point back to some original grid).
In computer graphics, there are certain matrices that can be used to apply a rotation, scaling, or translation. It is with these matrices that we'll begin our journey towards the final isometric projection.
Applying the transforms
Since the sprites being used are already pre-rendered the isometric projection. We only need to apply the following transforms:
- Translating the grid such that the origin is in the center of the grid.
- Scaling the grid to match the sprite size.
- Rotating the grid around the vertical axis by 45 degrees.
Toggle between a combination of the 3 transformations in the full example at the beginning of the post to visualize how each transform affects the final tile placement.
Above is an example of scaling the grid to the correct tile size, with the tiles attached
And here is the scaled grid after we rotate grid by 45 degree and the scale the grid so that the tiles overlap each other correctly.
Rotating to different view points
Armed with this knowledge, rotating the view for each different orientations of the grid is as easy as applying another rotation transform before we convert the grid into the isometric projection.
If we intend to mimic the rotation of SimCity 3000, there are only four set rotations, one for each corner of the map. This means from our initial view we will either be rotating 90 degrees clockwise, 90 degrees counter clockwise, or 180 degrees.
In matrix form, a rotation matrix would look like so:
$$ R = \begin{bmatrix} \cos(\theta) & -\sin(\theta) \\ \sin(\theta) & \cos(\theta) \\ \end{bmatrix} $$
Applied to some point (x, y)
:
$$ \begin{bmatrix} \cos(\theta) & -\sin(\theta) \\ \sin(\theta) & \cos(\theta) \end{bmatrix} \begin{bmatrix} x \\ y \\ \end{bmatrix} $$
And multiplied out:
$$ x' = x \cos(\theta) - y \sin(\theta) \\ y' = x \sin(\theta) + y \cos(\theta) $$
Now in code, this would look like so for some angle rot
:
1 let cos_rot = Math.cos(rot);
2 let sin_rot = Math.sin(rot);
3
4 let rx = (cx * cos_rot) - (cy * sin_rot);
5 let ry = (cx * sin_rot) + (cy * cos_rot);
For each rotation event, all we need to do is update the rot
angle that is
used to rotate the initial view and update the placement of each tile. As long
as we have an idea of how large our grid will be, we can apply these transformations
no matter where we're viewing the grid and have the terrain correctly rotate at the
location we're viewing.
Putting it all together
Combining the rotation with the earlier scaling and isometric projection, we get the following code:
1 // Center grid on the origin
2 let cx = x - GRID_WIDTH;
3 let cy = y - GRID_HEIGHT;
4
5 // Rotate around new origin
6 let cos_rot = Math.cos(rot);
7 let sin_rot = Math.sin(rot);
8
9 let rx = (cx * cos_rot) - (cy * sin_rot);
10 let ry = (cx * sin_rot) + (cy * cos_rot);
11
12 // Scale and rotate one last time to get into iso view.
13 // NOTE: Since a rotation of 45 degrees makes it so
14 // sin = cos = 0.707, I factor out the value since all
15 // it's doing is scaling the grid down.
16 let px = (rx - ry) * TILE_WIDTH / 2
17 let py = (rx + ry) * TILE_HEIGHT / 2;
18 let pz = -(rx + ry);
19
20 return [px, py, pz];
And there you have it! We've built an isometric view that also allows us to rotate everything however we please.

Unleash the power of flower this fall with a long breezy floral printed maxi and crop top.Double your style quotient this season by wearing floral on floral as seen on Dior, Thakoon and Alexander McQueen runways.
Play princess–for-a-day (at high tea if you please) in this romantic and breezy English floral print maxi accentuated with fuchsia pink details and a tie-up bow on the waistline.
With a burst of delicate spring colors and a gold zip detail in the center this finely printed crop top is a must have in your fall closet.
Floral patterns speak vibrant and stylish but if not matched correctly you may end up looking like a walking garden. Avoid the fashion faux pas by balancing floral prints with solid or pastel shades.
Can’t remember what the door to your gym says but still want to be Sonam Kapoor chic at your next get together? This long maxi sits at your waist highlighting the smallest part of your body and hiding that appalling muffin top and unkempt chicken legs.
Nothing looks as feminine and stunning as flowers on a girl. They’re so angelic yet phenomenally powerful. All my collections are very forward and draw on runways from all across the world.
This outfit for instance has a lot of influences from the 2015 spring/summer collections.
-Ms. Bhavya (Premier designer)
Grace yourself with this pretty number for a get together and gossip session with the your kitty or an exclusive exhibition. To play it down you could also team the skirt with a white or primrose crop top
Before stepping out primp your clothes with sprinkle of water, fabric softener and vinegar mix to keep them taught and wrinkle free.

Update your look this weekend go straight from day to night in this outfit by using the new Strobing (which is the new contouring by the way) technique and wearing this season’s favorite color — Oxblood.

The simple comparison operators <, >, <=, and >= compare the lower bounds first, and only if those are equal, compare the upper bounds. These comparisons are not usually very useful for ranges, but are provided to allow B-tree indexes to be done on ranges.
The left-of/right-of/adjacent operators always return false when an empty range is involved; that is, an empty range is not considered to be either before or after any other range.
The union and difference operators will fail if the resulting range would need to contain two disjoint sub-ranges, as such a range cannot be represented.

Check project documentation to verify that a security deployment review has been performed.
A deployment review helps to ensure that application security is not compromised by poor configuration of the network or host - even the most securely designed and implemented application can be compromised by an error during deployment.
Check project documentation to verify that a security deployment review has been performed. A security deployment review means reviewing the following categories for vulnerabilities:
Use following techniques when conducting a deployment review:
Use server security categories. Use server security categories to help make deployment reviews for security systematic and repeatable.
Break down your deployment review. You can use the categories to break down your application deployment for further analysis and to help identify vulnerabilities.
Review systematically. By using categories, you can systematically go through the deployment review process from start to finish or pick a particular category for further analysis.
Patterns & practices security guidance includes server security categories for each major application type. Use these categories as a starting point and add new items as you learn more about deployment reviews. Table 7.1 lists categories that are common to most deployed applications.
Patches and Updates. Installing patches and updates fixes known vulnerabilities with relatively little effort, so it is a good first step.
Accounts. Only grant access that is required for users to perform their job functions. Remove accounts that are not used and disable accounts that have been idle for a long time. Require strong passwords and password changes to make password-guessing attacks ineffective. Log authentication failure and warn users to become aware of attacks on user accounts.
Auditing and Logging. Logging is one of the most useful tools for becoming aware of attacks and for investigating attacks that have already occured. Enable and configure logging. Ideally, logs should be sent to a centralized log server where they are monitored in real time or reviewed daily.
Files and Directories. Configure access controls to only allow authorized users and services to access data. Access controls should be configured with "deny-all" defaults. Log unauthorized data access events.
Ports. Open ports accept incoming connections over the network. This makes them a simple attack vector. Scan your server for open ports to make sure that unsecure or unnecessary services are not running on your server.
Protocols. Some protocols have been designed without security in mind. Avoid using protocols that are known to have security vulnerabilities, such as FTP, which transmits authentication credentials in plain-text. If such protocols are necessary for operations, use additional security technologies, such as VPN, to provide secure communications and authentication.
Registry. Secure configuration settings stored in the registry by using ACLs and by disabling the remote registry service.
Services. Disable unused services. Secure, configure, and monitor important services. If a service that is known to be unsecure, such as FTP, but is necessary for operations is used, considering using a secure alternative or using additional security technologies to protect it.
Shares. Protect file shares with access controls only allowing the minimum required amount of access to the smallest necessary set of data. Remove any unused file shares.
Application security categories are different for different applications. Some application types will require review of application security categories as well as server security categories. For example, you should review application-level Web.config file settings for ASP.NET applications. Use server security categories as a starting point, and add new items as you learn more about deployment reviews.


FAST, CHEAP & OUT OF CONTROL
A Film Review by James Berardinelli
RATING (0 TO 10): 8.0 Alternative Scale: ***1/2 out of ****
United States, 1997 U.S. Release Date: beginning 10/3/97 (limited) Running Length: 1:22 MPAA Classification: PG (Nothing offensive) Theatrical Aspect Ratio: 1.85:1
Featuring: Dave Hoover, George Mendonca, Ray Mendez, Rodney Brooks Director: Errol Morris Producer: Errol Morris Cinematography: Robert Richardson Music: Caleb Sampson U.S. Distributor: Sony Pictures Classics
Perhaps you have the same reaction to documentaries that I do. In general, they aren't my favorite type of movie, and it's usually only with a degree of reluctance that I see even a highly praised member of the genre. Despite my misgivings, however, I almost always come away educated and intrigued, provided, of course, that the film maker has a clear idea of what he or she is doing. And, in the case of Errol Morris, the man who made one of the best-ever documentaries (THE THIN BLUE LINE), the strength of presentation couldn't be more apparent.
FAST, CHEAP & OUT OF CONTROL isn't much like any of Morris' other well-known films -- GATES OF HEAVEN (about a pet cemetery), THE THIN BLUE LINE (about a murder), and A BRIEF HISTORY OF TIME (about science, space, and infinity). In fact, at first glance, this movie appears startlingly unambitious by comparison -- the kind of project one might encounter any night on PBS or the Discovery Channel. But there's more to FAST, CHEAP & OUT OF CONTROL than initially meets the eye. Not only is there a great deal of craft involved in the film's production, but its underlying themes are compelling and universal.
The basic framework for FAST, CHEAP & OUT OF CONTROL has Morris interviewing four men with unique, but not terribly interesting, professions. Dave Hoover is a wild animal trainer who works with lions and tigers in the circus ring. George Mendonca is the topiary gardener (the person who sculpts hedges into lifelike shapes) for Green Animals' Gardens. Ray Mendez is a mole-rat specialist (mole-rats are hairless mammals that live in insect-like colonies). And Rodney Brooks is a robot scientist who works in an artificial intelligence lab at M.I.T. All four of these individuals are among the best in their respective fields, and it's their passion for their jobs, rather than anything especially startling or hypnotic about the work itself, that piques our interest.
As we watch, however, we become aware that, by structuring FAST, CHEAP & OUT OF CONTROL as he does, Morris is doing far more than merely presenting a series of talking-head interviews. By piecing the film together with fast cuts and sequences where the soundtrack of one interview overlaps images depicting the activities of another of the subjects, Morris explores at least two intriguing, interrelated themes: the evolution of humankind and our never-ending attempt to control our environment.
Contrast is a critical element. Hoover, with his wild animals and his stories about serial film star Clyde Beatty, belongs to a business (the circus) that is losing out to the glitz of modern-day entertainment. Likewise, Mendonca is one of the last of a dying breed. On the other hand, Mendez, with his observations about how the survival instincts of mole-rats exceed those of humans, and Brooks, who postulates that robots may ultimately outlive their creators, are men whose skill and knowledge place them on the road to the future. Shaped by an ever-changing cultural and technical climate, jobs, like people, evolve. By telling all four stories, Morris gives us a sense of what will be lost and what may be gained as time moves on. FAST, CHEAP & OUT OF CONTROL functions as a requiem for the past and a nod to the future.
One thing that never changes, however, is man's desire to regulate everything around him. Brooks speaks of his robots being the forerunners of a new breed of silicon-based life form that may eventually render our species extinct. Despite his assertion that he is only an observer, Mendez takes an important role in shaping the existence of his mole-rats, hoping to learn more about himself through their actions. Hoover's entire livelihood is based on mastering creatures that are more powerful and dangerous than himself. And even the mild-mannered Mendonca alters the course of nature by twisting and shaping bushes into works of art. In one way or another, all four are playing god.
 The answer, simply and succinctly, is Errol Morris, who has the talent to give meaning to even the most apparently- mundane material. Spending time with the four subjects of FAST, CHEAP & OUT OF CONTROL isn't just an opportunity to learn about what they do, but, surprisingly, a chance to understand a little more about our place in the universe.

An efficient implementation of a dynamically-allocated sparse 2D array.
This is a self-allocating and de-allocating 2D array that is optimized for numerical computation. It is modified from CompleteMatrix, but with a totally different, sparse implementation, including optimization of the math operations to take advantage of sparseness. More specifically, if the size of the array is NxN and the average number of non-zero entries in a row or column is M, then this implementation is intended to provide O(M) time scanning of all non-zero entries in a row or column and O(1) time access of the item at arbitrary location (i,j). The maximum number of items that a SparseMatrix can hold is sqrt(rows * columns).
This magic is accomplished by storing non-zero elements as part of three data structures simultaneously:

Access value of element at (row, column) – mutator.
Constant time as long as number of items in the N x M SparseMatrix is less than 4*sqrt(N*M). If there is no element at the given location, then a zero value one is created. This is done because this method is usable as a mutator: it returns a reference to the value in the specified element. If this becomes a problem in other code, then the solution would be to add an accessor that either throws an exception if an element doesn't exist or that returns both the element value and a success/failure flag.
