• View and Flip Between Firefox Tabs in 3D

  - by Asian Angel

  Are you tired of the default tab switching style in Firefox? Then get ready to enjoy a more visually pleasing 3D experience with the FoxTab extension. Using FoxTab As soon as you have the extension installed, you will see a new toolbar button available beside the address bar. Before going further you may want to look through the viewing styles available in the lower right corner. Note: You can choose to have the FoxTab button appear in the status bar if preferred or use the keyboard (i.e. F12) by itself to launch FoxTab. The grid view with an angled 3D setting. The page flow view with a more frontal look. If the default background color is not to your liking then you can easily change to a new color or insert a background image. After choosing a new background color, making a few adjustments in the options, and opening more tabs things look very nice using the grid viewing style. Followed by the carousel viewing style. And finally the wall viewing style. You can also set up a top sites page using your favorite viewing style. To add a page to the top sites group right click within the webpage and select Add To Top Sites. Just like that your new selection is added in. Keep in mind that we were not able to move/switch positions in the grid during our tests. Options The extension has plenty of options and settings to help you customize FoxTab to your liking. Conclusion FoxTab adds visually pleasing 3D tab switching to Firefox for anyone who loves eye candy and a touch of fun while browsing.

• Aggregating cache data from OCEP in CQL

  - by Manju James

  There are several use cases where OCEP applications need to join stream data with external data, such as data available in a Coherence cache. OCEP’s streaming language, CQL, supports simple cache-key based joins of stream data with data in Coherence (more complex queries will be supported in a future release). However, there are instances where you may need to aggregate the data in Coherence based on input data from a stream. This blog describes a sample that does just that. For our sample, we will use a simplified credit card fraud detection use case. The input to this sample application is a stream of credit card transaction data. The input stream contains information like the credit card ID, transaction time and transaction amount. The purpose of this application is to detect suspicious transactions and send out a warning event. For the sake of simplicity, we will assume that all transactions with amounts greater than $1000 are suspicious. The transaction history is available in a Coherence distributed cache. For every suspicious transaction detected, a warning event must be sent with maximum amount, total amount and total number of transactions over the past 30 days, as shown in the diagram below. Application Input Stream input to the EPN contains events of type CCTransactionEvent. This input has to be joined with the cache with all credit card transactions. The cache is configured in the EPN as shown below: <wlevs:caching-system id="CohCacheSystem" provider="coherence"/> <wlevs:cache id="CCTransactionsCache" value-type="CCTransactionEvent" key-properties="cardID, transactionTime" caching-system="CohCacheSystem"> </wlevs:cache> Application Output The output that must be produced by the application is a fraud warning event. This event is configured in the spring file as shown below. Source for cardHistory property can be seen here. <wlevs:event-type type-name="FraudWarningEvent"> <wlevs:properties type="tuple"> <wlevs:property name="cardID" type="CHAR"/> <wlevs:property name="transactionTime" type="BIGINT"/> <wlevs:property name="transactionAmount" type="DOUBLE"/> <wlevs:property name="cardHistory" type="OBJECT"/> </wlevs:properties </wlevs:event-type> Cache Data Aggregation using Java Cartridge In the output warning event, cardHistory property contains data from the cache aggregated over the past 30 days. To get this information, we use a java cartridge method. This method uses Coherence’s query API on credit card transactions cache to get the required information. Therefore, the java cartridge method requires a reference to the cache. This may be set up by configuring it in the spring context file as shown below: <bean class="com.oracle.cep.ccfraud.CCTransactionsAggregator"> <property name="cache" ref="CCTransactionsCache"/> </bean> This is used by the java class to set a static property: public void setCache(Map cache) { s_cache = (NamedCache) cache; } The code snippet below shows how the total of all the transaction amounts in the past 30 days is computed. Rest of the information required by CardHistory object is calculated in a similar manner. Complete source of this class can be found here. To find out more information about using Coherence's API to query a cache, please refer Coherence Developer’s Guide. public static CreditHistoryData(String cardID) { … Filter filter = QueryHelper.createFilter("cardID = :cardID and transactionTime :transactionTime", map); CardHistoryData history = new CardHistoryData(); Double sum = (Double) s_cache.aggregate(filter, new DoubleSum("getTransactionAmount")); history.setTotalAmount(sum); … return history; } The java cartridge method is used from CQL as seen below: select cardID, transactionTime, transactionAmount, CCTransactionsAggregator.execute(cardID) as cardHistory from inputChannel where transactionAmount1000 This produces a warning event, with history data, for every credit card transaction over $1000. That is all there is to it. The complete source for the sample application, along with the configuration files, is available here. In the sample, I use a simple java bean to load the cache with initial transaction history data. An input adapter is used to create and send transaction events for the input stream.

• AWStats configuration issue [on hold]

  - by Dan

  I have a an Ubuntu 12.04.2 LTS server in which i host my website. The website is in Drupal. I tried to set up AWStats for my website but it is giving a lot of problems. I followed this link - http://www.sysadminworld.com/2011/set-up-awstats-on-ubuntu/ But I am confused about the domain name that needs to be given. The website can be accessed from http://xyz.com but the actual link is http://xyz.abc-def.com/root-folder. What is the domain name in this case? So what should be the name of the conf file then?

• Integration with Multiple Versions of BizTalk HL7 Accelerator Schemas

  - by Paul Petrov

  Microsoft BizTalk Accelerator for HL7 comes with multiple versions of the HL7 implementation. One of the typical integration tasks is to receive one format and transmit another. For example, system A works HL7 v2.4 messages, system B with v2.3, and system C with v2.2. The system A is exchanging messages with B and C. The logical solution is to create schemas in separate namespaces for each system and assign maps on send ports. Schematic diagram of the messaging solution is shown below:   Nothing is complex about that conceptually. On the implementation level things can get nasty though because of the elaborate nature of HL7 schemas and sheer amount of message types involved. If trying to implement maps directly in BizTalk Map Editor one would quickly get buried by thousands of links between subfields of HL7 segments. Since task is repetitive because HL7 segments are reused between message types it's natural to take advantage of such modular structure and reduce amount of work through reuse. Here's where it makes sense to switch from visual map editor to old plain XSLT. The implementation is done in three steps. First, create XSL templates to map from segments of one version to another. This can be done using BizTalk Map Editor subsequently copying and modifying generated XSL code to create one xsl:template per segment. Group all segments for format mapping in one XSL file (we call it SegmentTemplates.xsl). Here's how template for the PID segment (Patient Identification) would look like this: <xsl:template name="PID"> <PID_PatientIdentification> <xsl:if test="PID_PatientIdentification/PID_1_SetIdPatientId"> <PID_1_SetIdPid> <xsl:value-of select="PID_PatientIdentification/PID_1_SetIdPatientId/text()" /> </PID_1_SetIdPid> </xsl:if> <xsl:for-each select="PID_PatientIdentification/PID_2_PatientIdExternalId"> <PID_2_PatientId> <xsl:if test="CX_0_Id"> <CX_0_Id> <xsl:value-of select="CX_0_Id/text()" /> </CX_0_Id> </xsl:if> <xsl:if test="CX_1_CheckDigit"> <CX_1_CheckDigitSt> <xsl:value-of select="CX_1_CheckDigit/text()" /> </CX_1_CheckDigitSt> </xsl:if> <xsl:if test="CX_2_CodeIdentifyingTheCheckDigitSchemeEmployed"> <CX_2_CodeIdentifyingTheCheckDigitSchemeEmployed> <xsl:value-of select="CX_2_CodeIdentifyingTheCheckDigitSchemeEmployed/text()" /> </CX_2_CodeIdentifyingTheCheckDigitSchemeEmployed> . . . // skipped for brevity This is the most tedious and time consuming part. Templates can be created for only those segments that are used in message interchange. Once this is done the rest goes much easier. The next step is to create message type specific XSL that references (imports) segment templates XSL file. Inside this file simple call segment templates in appropriate places. For example, beginning of the mapping XSL for ADT_A01 message would look like this:   <xsl:import href="SegmentTemplates_23_to_24.xslt" />  <xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />   <xsl:template match="/">    <xsl:apply-templates select="s0:ADT_A01_23_GLO_DEF" />  </xsl:template>   <xsl:template match="s0:ADT_A01_23_GLO_DEF">    <ns0:ADT_A01_24_GLO_DEF>      <xsl:call-template name="EVN" />      <xsl:call-template name="PID" />      <xsl:for-each select="PD1_PatientDemographic">        <xsl:call-template name="PD1" />      </xsl:for-each>      <xsl:call-template name="PV1" />      <xsl:for-each select="PV2_PatientVisitAdditionalInformation">        <xsl:call-template name="PV2" />      </xsl:for-each> This code simply calls segment template directly for required singular elements and in for-each loop for optional/repeating elements. And lastly, create BizTalk map (btm) that references message type specific XSL. It is essentially empty map with Custom XSL Path set to appropriate XSL: In the end, you will end up with one segment templates file that is referenced by many message type specific XSL files which in turn used by BizTalk maps. Once all segment maps are created they are widely reusable and all the rest work is very simple and clean.

• Converting 2D Physics to 3D.

  - by static void main

  I'm new to game physics and I am trying to adapt a simple 2D ball simulation for a 3D simulation with the Java3D library. I have this problem: Two things: 1) I noted down the values generated by the engine: X/Y are too high and minX/minY/maxY/maxX values are causing trouble. Sometimes the balls are drawing but not moving Sometimes they are going out of the panel Sometimes they're moving on little area Sometimes they just stick at one place... 2) I'm unable to select/define/set the default correct/suitable values considering the 3D graphics scaling/resolution while they are set with respect to 2D screen coordinates, that is my only problem. Please help. This is the code: public class Ball extends GameObject { private float x, y; // Ball's center (x, y) private float speedX, speedY; // Ball's speed per step in x and y private float radius; // Ball's radius // Collision detected by collision detection and response algorithm? boolean collisionDetected = false; // If collision detected, the next state of the ball. // Otherwise, meaningless. private float nextX, nextY; private float nextSpeedX, nextSpeedY; private static final float BOX_WIDTH = 640; private static final float BOX_HEIGHT = 480; /** * Constructor The velocity is specified in polar coordinates of speed and * moveAngle (for user friendliness), in Graphics coordinates with an * inverted y-axis. */ public Ball(String name1,float x, float y, float radius, float speed, float angleInDegree, Color color) { this.x = x; this.y = y; // Convert velocity from polar to rectangular x and y. this.speedX = speed * (float) Math.cos(Math.toRadians(angleInDegree)); this.speedY = speed * (float) Math.sin(Math.toRadians(angleInDegree)); this.radius = radius; } public void move() { if (collisionDetected) { // Collision detected, use the values computed. x = nextX; y = nextY; speedX = nextSpeedX; speedY = nextSpeedY; } else { // No collision, move one step and no change in speed. x += speedX; y += speedY; } collisionDetected = false; // Clear the flag for the next step } public void collideWith() { // Get the ball's bounds, offset by the radius of the ball float minX = 0.0f + radius; float minY = 0.0f + radius; float maxX = 0.0f + BOX_WIDTH - 1.0f - radius; float maxY = 0.0f + BOX_HEIGHT - 1.0f - radius; double gravAmount = 0.9811111f; double gravDir = (90 / 57.2960285258); // Try moving one full step nextX = x + speedX; nextY = y + speedY; System.out.println("In serializedBall in collision."); // If collision detected.

• MySQL for Excel 1.1.0 GA has been released

  - by Javier Treviño

  The MySQL Windows Experience Team is proud to announce the release of MySQL for Excel version 1.1.0 GA, one of our newest products contained in the MySQL Installer suite. You can download it from our official Downloads page at http://dev.mysql.com/downloads/installer/. The 1.1.0 release of MySQL for Excel introduces the following features: Edit MySQL Data. Edit MySQL Data This may be the coolest feature so far; users will be able to edit the data in a MySQL table using MS Excel in a very friendly and intuitive way.  Edit Data supports inserting new rows, deleting existing rows and updating existing data as easy as playing with data in an Excel’s spreadsheet and pushing changes back to the server.  Also this version contains the following bug fixes: Enabled the following checkboxes in the Append Data's Advanced Options dialog and added code in the Append Data dialog to use the checkboxes as follows: Automatically store the column mapping for the given table     If checked the current mapping will be stored automatically after clicking the Append button if the append operation is successful and there is no mapping for the current connection.schema.table already; the new mapping is stored with a proposed name of Mapping. Reload stored column mapping for the selected table automatically     If checked the first Stored Mapping found where all column names in the source grid match all column names in the target grid is automatically selected and applied when the Append Data dialog is loaded. Fixed code in Append Data that applies a stored column mapping to skip target columns where the associated mapping is empty (saved as a -1). Enclosed the Add-In's startup code in a try-catch block in order to log any possible error thrown during startup; and added information messages to the log at the beginning of the Add-In's startup code and at the end of the shutdown code.  Also changed the wrapper method that calls the MySQLUtility to write messages to the log to make logging easier, thus changed the log call throughout all the code that contains a try-catch block. Added code to the main wix configuration file to check if a newer version is already installed and if so abort the installation Fixed code to refresh the Import Procedure Form's preview grid's data source to repaint its contents every time the Call button is pressed. Added code to re-pull connections after connections are migrated from Excel to Workbench. Fixed code so when the Append Data's Automatic Mapping is performed any subsequent change on a mapping resets the mapping to a Manual Mapping. Added code to the InfoDialog class to set the button text to "Show Details" or "Hide Details" depending on the status of the Details text container. Fixed a GUID in the main wix configuration file so now previous versions are uninstalled during a new installation. Added an option to the Export Data's Advanced Options dialog to remove columns with no data, by default the Export Dialog will only flag those columns as Excluded. Added code to display a warning and paint a column red if the column name in the Export Data dialog is not set, display a warning if the table name is not set, and stack warnings but not display them if a column is Excluded, warnings are displayed normally for columns if they are not Excluded anymore.  Added code to prevent the Append and Export of Data if more than 1 selection is made (selecting more than 1 area holding the Ctrl key while selecting Excel cells). Fixed problem that prevented MySQL for Excel from loading when Display settings in Windows 7 is set to Adjust to Best Performance (Oracle bug 14521405 - UNHANDLED EXCEPTION IS THROWN WHEN LOADING MYSQL FOR EXCEL). Fixed code that renames the auto-generated Primary Key column when the Table name changes since it was not detecting if a column with the same name already existed in the table. The column duplication was not actually happening, it looked that way because the automatically generated PK column was not detecting a column had that same name. Fixed code in Export Data dialog to always set an empty string instead of null to the MySQLDataColumn properties that stores MySQL data types (MySQLDataType, RowsFrom1stDataType and RowsFrom2ndDataType). Added code to display a warning and color red a column which Data Type has not been set by the user or has been manually cleared. Added code to output to the application log exception messages consistently in all places where exceptions are catched. A series of blog posts explaining the new Edit MySQL Data feature and the other existing features are coming in this blog. You can access the MySQL for Excel documentation at http://dev.mysql.com/doc/refman/5.5/en/mysql-for-excel.html You can also post questions on our MySQL for Excel forum found at http://forums.mysql.com/. You can also post questions on our MySQL for Excel forum found at http://forums.mysql.com/. Enjoy and thanks for the support!

• Differences between fish and bash to pass commandline arguments to alias functions?

  - by NES

  From the answers to my other question here i learned about the possibility to pass commandline arguments to a alias function in Bash. In Fish i can edit an alias by editing the file config.fish in ~/.config/fish directory and adding a line like this alias lsp='ls -ah --color=always | less -R;' and it works perfectly. This should be the equivalent to editing ~/.bash_aliases in bash But when i try to setup an alias function to pass arguments like this alias lsp='_(){ ls -ah --color=always $* | less -R; }; _' it doesn't work for fish? Are there any differences between fish and bash in the way to setup an alias to pass commandline arguments that prevent this second alias from working with fish instead of bash?

• How to customize the gnome classic panel

  - by Luis Alvarado

  First the picture: As you can see in the image, the color used for the icons and words Applications and Places (In spanish in this case) they have a different background dark gray color than the rest of the panel. Also the icons look rather bigger in that panel. Now my questions are: Can the background colors be customized so they look the same all the way in the panel. Can the icons be somehow minimized a little so they do not look strange (bigger actually) How to edit the way to add icons to the panel. I have to actually have to press the ALT key then right click on it to add something. That extra key is not friendly at all. In this particular case am trying to help an older man start in Ubuntu. Unity is too much for him but Gnome is friendlier for him (Learning curve is not the best for older people.. specially 68+ year old people).

  I have some questions regarding the following css that I found: html, body { height:100%; min-width:100%; position:absolute; } html { background: none repeat scroll 0 0 #fff; color:#fff; font-family:arial,helvetica,sans-serif; font-size:15px; } is it necessary to have height and min-width to 100% on the html and body? What's the benefit? what is the reason for using position absolute? why did they set the background/color/font on the html and not the body? Is there a difference? Or is it just preference?

• "Marching cubes" voxel terrain - triplanar texturing with depth?

  - by Dan the Man

  I am currently working on a voxel terrain that uses the marching cubes algorithm for polygonizing the scalar field of voxels. I am using a triplanar texturing shader for texturing. say I have a grass texture set to the Y axis and a dirt texture for both the X and Z axes. Now, when my player digs downwards, it still appears as grass. How would I make it to appear as dirt? I have been thinking about this for a while, and the only thing I can think of to make this effect, would be to mark vertices that have been dug with a certain vertex color. When it has that vertex color, the shader would apply that dirt texture to the vertices marked. Is there a better method?

  - by Arthur Wulf White

  I want to write a shader/filer probably in adobe Pixel Bender that will do the best job possible in emulating the fill of an oldskul monochromatic arcade CRT screen. Much like this here: http://filthypants.blogspot.com/2012/07/customizing-cgwgs-crt-pixel-shader.html Here are some attributes I know will exist in this filter: It will take in a low res image 160 x 120 and return a medium res image 640 x 480. It will add scanlines It will blur the color channels to create that color bleeding effect It will distort the shape of the image from a perfect rectangle into a rounder shape. The question is, could you please provide any other attributes that are beneficial to emulating an arcade CRT feel and links and resources on coding these effects. Thanks

• vb.net and mysql connectivity [closed]

  - by kalpana

  I have used adodb using odbc database connectivity for connecting vb.net to mysql. I have fetched table values into recordset. I want to fetch only one column values (for example, table name-login, column name-password and values in password column are "manage","sales","general"). I want to fetch these values in text boxes. I have written code but it's not working. Dim conn As New ADODB.Connection Dim res As New ADODB.Recordset conn.Open("test", "root", "root") res = conn.Execute("select password from login") textbox1.text=res(0).value textbox2.text=res(1).value textbox3.text=res(2).value I am getting data in textbox1 but other data is not getting inserted into textbox2 and textbox3..I am getting error i.e (1) Item cannot be found in the collection corresponding to the requested name or ordinal.

• Running a Mongo Replica Set on Azure VM Roles

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/10/15/running-a-mongo-replica-set-on-azure-vm-roles.aspxSetting up a MongoDB Replica Set with a bunch of Azure VMs is straightforward stuff. Here’s a step-by-step which gets you from 0 to fully-redundant 3-node document database in about 30 minutes (most of which will be spent waiting for VMs to fire up). First, create yourself 3 VM roles, which is the minimum number of nodes you need for high availability. You can use any OS that Mongo supports. This guide uses Windows but the only difference will be the mechanism for starting the Mongo service when the VM starts (Windows Service, daemon etc.) While the VMs are provisioning, download and install Mongo locally, so you can set up the replica set with the Mongo shell. We’ll create our replica set from scratch, doing one machine at a time (if you have a single node you want to upgrade to a replica set, it’s the same from step 3 onwards): 1. Setup Mongo Log into the first node, download mongo and unzip it to C:. Rename the folder to remove the version – so you have c:\MongoDB\bin etc. – and create a new folder for the logs, c:\MongoDB\logs. 2. Setup your data disk When you initialize a node in a replica set, Mongo pre-allocates a whole chunk of storage to use for data replication. It will use up to 5% of your data disk, so if you use a Windows VM image with a defsault 120Gb disk and host your data on C:, then Mongo will allocate 6Gb for replication. And that takes a while. Instead you can create yourself a new partition by shrinking down the C: drive in Computer Management, by say 10Gb, and then creating a new logical disk for your data from that spare 10Gb, which will be allocated as E:. Create a new folder, e:\data. 3. Start Mongo When that’s done, start a command line, point to the mongo binaries folder, install Mongo as a Windows Service, running in replica set mode, and start the service: cd c:\mongodb\bin mongod -logpath c:\mongodb\logs\mongod.log -dbpath e:\data -replSet TheReplicaSet –install net start mongodb 4. Open the ports Mongo uses port 27017 by default, so you need to allow access in the machine and in Azure. In the VM, open Windows Firewall and create a new inbound rule to allow access via port 27017. Then in the Azure Management Console for the VM role, under the Configure tab add a new rule, again to allow port 27017. 5. Initialise the replica set Start up your local mongo shell, connecting to your Azure VM, and initiate the replica set: c:\mongodb\bin\mongo sc-xyz-db1.cloudapp.net rs.initiate() This is the bit where the new node (at this point the only node) allocates its replication files, so if your data disk is large, this can take a long time (if you’re using the default C: drive with 120Gb, it may take so long that rs.initiate() never responds. If you’re sat waiting more than 20 minutes, start another instance of the mongo shell pointing to the same machine to check on it). Run rs.conf() and you should see one node configured. 6. Fix the host name for the primary – *don’t miss this one* For the first node in the replica set, Mongo on Windows doesn’t populate the full machine name. Run rs.conf() and the name of the primary is sc-xyz-db1, which isn’t accessible to the outside world. The replica set configuration needs the full DNS name of every node, so you need to manually rename it in your shell, which you can do like this: cfg = rs.conf() cfg.members[0].host = ‘sc-xyz-db1.cloudapp.net:27017’ rs.reconfig(cfg) When that returns, rs.conf() will have your full DNS name for the primary, and the other nodes will be able to connect. At this point you have a working database, so you can start adding documents, but there’s no replication yet. 7. Add more nodes For the next two VMs, follow steps 1 through to 4, which will give you a working Mongo database on each node, which you can add to the replica set from the shell with rs.add(), using the full DNS name of the new node and the port you’re using: rs.add(‘sc-xyz-db2.cloudapp.net:27017’) Run rs.status() and you’ll see your new node in STARTUP2 state, which means its initializing and replicating from the PRIMARY. Repeat for your third node: rs.add(‘sc-xyz-db3.cloudapp.net:27017’) When all nodes are finished initializing, you will have a PRIMARY and two SECONDARY nodes showing in rs.status(). Now you have high availability, so you can happily stop db1, and one of the other nodes will become the PRIMARY with no loss of data or service. Note – the process for AWS EC2 is exactly the same, but with one important difference. On the Azure Windows Server 2012 base image, the MongoDB release for 64-bit 2008R2+ works fine, but on the base 2012 AMI that release keeps failing with a UAC permission error. The standard 64-bit release is fine, but it lacks some optimizations that are in the 2008R2+ version.

• Firefox ignore GTK theme for localhost stuff

  - by Mario De Schaepmeester

  I know this is pretty much a duplicate of How can one make firefox ignore my GTK theme entirely?, but the answers on that one are no permanent solution. It works by launching firefox from the terminal. I would like to know a solution that works for every instance of firefox no matter how it was created. There is the possibility to edit the userContent.css file, but the settings you make randomly do not apply to some sites or in some situations, strangely, even with the !important added... I have a dark GTK theme and this results in some textboxes having a black background with black text with a userContent.css that has input, textarea { color: black !important; background-color: white !important; } Update I changed a setting in about:config from true to false, namely browser.display.use_system_colors. Everything appears normal and well now, for one exception: everything that runs on localhost. This includes PHPMyAdmin and a website I am making. I would like to know if there is a solution to this.

• Apache Commons PropertiesConfiguration escapes characters on Save [migrated]

  - by Anuvrat

  I am using the commons-configuration from apache commons library. I have a properties file which has properties like: blog_loc=http://my.blog.com blog_name="my blog name" I open the properties file, change the blog_name property and save the file. The following are the lines of code I use: PropertiesConfiguration propertyFile = new PropertiesConfiguration(propertyFileName); propertyFile.setProperty(blog_name, "blog name"); propertyFile.save(propertyFileName + ".out"); Unfortunately, in the output file certain characters get escaped as follows: blog_loc=http:\/\/my.blog.com blog_name=\"blog name\" Is there any way of preventing escaping of the above characters?

• Sort method versus OrderBy LINQ extension method

  - by nmarun

  I have a class Product with an Id and a Name as properties. There are multiple ways of getting a list of products to display in sorted/ordered fashion, say, by the Name of the product. The two I’m concerned about here are the Sort and the OrderBy extension method through LINQ and the difference between them. 1: public class Product 2: { 3: public int Id { get; set; } 4: public string Name { get; set; } 5: } Below is the list of products that I’ll be using and is defined somewhere in the Program.cs...(read more)

• Why do my 512x512 bitmaps look jaggy on Android OpenGL?

  - by Milo Mordaunt

  This is sort of driving me nuts, I've googled and googled and tried everything I can think of, but my sprites still look super blurry and super jaggy. Example: Here: https://docs.google.com/open?id=0Bx9Gbwnv9Hd2TmpiZkFycUNmRTA If you click through to the actual full size image you should see what I mean, it's like it's taking and average of every 5*5 pixels or something, the background looks really blurry and blocky, but the ball is the worst. The clouds look all right for some reason, probably because they're mostly transparent. I know the pngs aren't top notch themselves but hey, I'm no artist! I would imagine it's a problem with either: a. How the pngs are made example sprite (512x512): https://docs.google.com/open?id=0Bx9Gbwnv9Hd2a2RRQlJiQTFJUEE b. How my Matrices work This is the relevant parts of the renderer: public void onDrawFrame(GL10 unused) { if(world != null) { dt = System.currentTimeMillis() - endTime; world.update( (float) dt); // Redraw background color GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT); Matrix.setIdentityM(mvMatrix, 0); Matrix.translateM(mvMatrix, 0, 0f, 0f, 0f); world.draw(mvMatrix, mProjMatrix); endTime = System.currentTimeMillis(); } else { Log.d(TAG, "There is no world...."); } } public void onSurfaceChanged(GL10 unused, int width, int height) { GLES20.glViewport(0, 0, width, height); Matrix.orthoM(mProjMatrix, 0, 0, width /2, 0, height /2, -1.f, 1.f); } And this is what each Quad does when draw is called: public void draw(float[] mvMatrix, float[] pMatrix) { Matrix.setIdentityM(mMatrix, 0); Matrix.setIdentityM(mvMatrix, 0); Matrix.translateM(mMatrix, 0, xPos, yPos, 0.f); Matrix.multiplyMM(mvMatrix, 0, mvMatrix, 0, mMatrix, 0); Matrix.scaleM(mvMatrix, 0, scale, scale, 0f); Matrix.rotateM(mvMatrix, 0, angle, 0f, 0f, -1f); GLES20.glUseProgram(mProgram); posAttr = GLES20.glGetAttribLocation(mProgram, "vPosition"); texAttr = GLES20.glGetAttribLocation(mProgram, "aTexCo"); uSampler = GLES20.glGetUniformLocation(mProgram, "uSampler"); int alphaHandle = GLES20.glGetUniformLocation(mProgram, "alpha"); GLES20.glVertexAttribPointer(posAttr, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, 0, vertexBuffer); GLES20.glVertexAttribPointer(texAttr, 2, GLES20.GL_FLOAT, false, 0, texCoBuffer); GLES20.glEnableVertexAttribArray(posAttr); GLES20.glEnableVertexAttribArray(texAttr); GLES20.glActiveTexture(GLES20.GL_TEXTURE0); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, texture); GLES20.glUniform1i(uSampler, 0); GLES20.glUniform1f(alphaHandle, alpha); mMVMatrixHandle = GLES20.glGetUniformLocation(mProgram, "uMVMatrix"); mPMatrixHandle = GLES20.glGetUniformLocation(mProgram, "uPMatrix"); GLES20.glUniformMatrix4fv(mMVMatrixHandle, 1, false, mvMatrix, 0); GLES20.glUniformMatrix4fv(mPMatrixHandle, 1, false, pMatrix, 0); GLES20.glDrawElements(GLES20.GL_TRIANGLE_STRIP, 4, GLES20.GL_UNSIGNED_SHORT, indicesBuffer); GLES20.glDisableVertexAttribArray(posAttr); GLES20.glDisableVertexAttribArray(texAttr); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, 0); } c. How my texture loading/blending/shaders setup works Here is the renderer setup: public void onSurfaceCreated(GL10 unused, EGLConfig config) { // Set the background frame color GLES20.glClearColor(0.0f, 0.0f, 0.0f, 1.0f); GLES20.glDisable(GLES20.GL_DEPTH_TEST); GLES20.glDepthMask(false); GLES20.glBlendFunc(GLES20.GL_ONE, GLES20.GL_ONE_MINUS_SRC_ALPHA); GLES20.glEnable(GLES20.GL_BLEND); GLES20.glEnable(GLES20.GL_DITHER); } Here is the vertex shader: attribute vec4 vPosition; attribute vec2 aTexCo; varying vec2 vTexCo; uniform mat4 uMVMatrix; uniform mat4 uPMatrix; void main() { gl_Position = uPMatrix * uMVMatrix * vPosition; vTexCo = aTexCo; } And here's the fragment shader: precision mediump float; uniform sampler2D uSampler; uniform vec4 vColor; varying vec2 vTexCo; varying float alpha; void main() { vec4 color = texture2D(uSampler, vec2(vTexCo)); gl_FragColor = color; if(gl_FragColor.a == 0.0) { "discard; } } This is how textures are loaded: private int loadTexture(int rescource) { int[] texture = new int[1]; BitmapFactory.Options opts = new BitmapFactory.Options(); opts.inScaled = false; Bitmap temp = BitmapFactory.decodeResource(context.getResources(), rescource, opts); GLES20.glGenTextures(1, texture, 0); GLES20.glActiveTexture(GLES20.GL_TEXTURE0); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, texture[0]); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_LINEAR); GLUtils.texImage2D(GLES20.GL_TEXTURE_2D, 0, temp, 0); GLES20.glGenerateMipmap(GLES20.GL_TEXTURE_2D); GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, 0); temp.recycle(); return texture[0]; } I'm sure I'm doing about 20,000 things wrong, so I'm really sorry if the problem is blindingly obvious... The test device is a Galaxy Note, running a JellyBean custom ROM, if that matters at all. So the screen resolution is 1280x800, which means... The background is 1024x1024, so yeah it might be a little blurry, but shouldn't be made of lego. Thank you so much, any answer at all would be appreciated.

• Missed environment variables in Eclipse Juno

  - by hara

  I recently moved from Eclipse Indigo to Juno. I installed the IDE in my Ubuntu 12.04 by downloading the archive from here. Then I created an entry in the unity launcher for Juno as I done before for Indigo. Here is what I wrote in ~/.local/share/applications/eclipse-juno.desktop: [Desktop Entry] Type=Application Name=Eclipse Juno Comment=Eclipse Integrated Developmentm Environment Icon=~/.eclipse-juno/icon.xpm Exec=~/.eclipse-juno/eclipse -vmargs -Duser.name="my name" Terminal=false Categories=Development;IDE;Java; When I run eclipse from the unity launcher, eclipse does not see environment variables that I set in ~/.bascrc. Instead, if I run eclipse from shell, it can see all the env variables. How can I fix the problem? Thanks a lot.
