  • How to use batch rendering with an entity component system?

    - by Kiril
    I have an entity component system and a 2D rendering engine. Because I have a lot of repeating sprites (the entities are non-animated, the background is tile based) I would really like to use batch rendering to reduce calls to the drawing routine. What would be the best way to integrate this with an engtity system? I thought about creating and populating the sprite batche every frame update, but that will probably be very slow. A better way would be to add a reference to an entity's quad to the sprite batch at initialization, but that would mean that the entity factory has to be aware of the Rendering System or that the sprite batch has to be a component of some Cache entity. One case violates encapsulation pretty heavily, while the other forces a non-game object entity in the entity system, which I am not sure I like a lot. As for engine, I am using Love2D (Love2D website) and FEZ ( FEZ website) as entity system(so everything is in Lua). I am more interested in a generic pattern of how to properly implement that rather than a language/library specific solution. Thanks in advance!

  • How to backup and restore everything of foobar2000?

    - by Dennis
    What is the best way to backup and restore all my everything in Foobar2000? I was once clicked on a "Reset all" button which provide somehow a stupid feature - clear all setting and playlist. The story tell that, remember to do backup when there is nothing goes wrong. (And I don't think they should put the button on the middle of all the configuration screen.) But how? Are there any script or plugins to help me to backup all settings? I cannot find a button of export or import my settings.

  • Oracle JDK 7u10 released with new security features

    - by Henrik Stahl
    A few days ago, we released JRE and JDK 7 update 10. This release adds support for the following new platforms: Windows 8 on x86-64. Note that Modern UI (aka Metro) mode is not supported. Internet Explorer 10 on Windows 8. Mac OS X 10.8 (Mountain Lion) This release also introduces new features that provide enhanced security for Java applet and webstart applications, specifically: The Java runtime tracks if it is updated to the latest security baseline. If you try to execute an unsigned applet with an outdated version of Java, a warning dialog will prompt you to update before running the applet. The Java runtime includes a hardcoded best before date. It is assumed that a new version will be released before this date. If the client has not been able to check for an update prior to this date, the Java runtime will assume that it is insecure and start warning the user prior to executing any applets. The Java control panel now includes an option to set the desired security level on a low-medium-high-very high scale, as well as an option to disable Java applets and webstart entirely. This level controls things such as if the Java runtime is allowed to execute unsigned code, and if so what type of warning will be displayed to the user. More details on the security settings can be found in the documentation. See below for a sample screenshot. The new update of the JRE and the JDK are available via OTN. To learn more about the release please visit the release notes.

  • What is the fastest way to reload history commands begin with certain characters in linux?

    - by gerry
    In Dos we can input the first several characters to filter command history and find proper one rapidly. But how to do the same thing in Linux ? for example when I am testing a local server: cd sudo /etc/init.d/vsftpd start wget ... ls emacs ... sudo /etc/init.d/vsftpd restart sudo /etc/init.d/vsftpd stop ... In Dos you can easily type sudo and switch among the three commands beginning with it using arrow keys. But in Linux, is below command the best we can do ? historty | grep sudo I don't like it, because history can easily become a mess, and it also need mouse action.

  • SQL Server 2000 need to prevent logons whilst performing a backup for a side by side migration

    - by pigeon
    I'm looking for a way to prevent logons from occurring in order to take a full backup of a Database to migrate from its current SQL Server 2000 instance to a new SQL 2005 instance. A friend of mine suggested running a script which would put the DB into a rollback state. Not being a DBA my DDL is very poor and running a script that I don't understand may not be the best idea. One option which might be easier is to simply detach and copy, to the new server. Any suggestions would be greatly appreciated.

  • How to securely delete files stored on a SSD?

    - by Chris Neuroth
    From a (very long, but definitely worth to read) article on SSDs: When you delete a file in your OS, there is no reaction from either a hard drive or SSD. It isn’t until you overwrite the sector (on a hard drive) or page (on a SSD) that you actually lose the data. File recovery programs use this property to their advantage and that’s how they help you recover deleted files. The key distinction between HDDs and SSDs however is what happens when you overwrite a file. While a HDD can simply write the new data to the same sector, a SSD will allocate a new (or previously used) page for the overwritten data. The page that contains the now invalid data will simply be marked as invalid and at some point it’ll get erased. So, what would be the best way to securely erase files stored on a SSD? Overwriting with random data as we are used to from hard disks (e.g. using the "shred" utility) won't work unless you overwrite the WHOLE drive...

  • Preffered lambda syntax?

    - by Roger Alsing
    I'm playing around a bit with my own C like DSL grammar and would like some oppinions. I've reserved the use of "(...)" for invocations. eg: foo(1,2); My grammar supports "trailing closures" , pretty much like Ruby's blocks that can be passed as the last argument of an invocation. Currently my grammar support trailing closures like this: foo(1,2) { //parameterless closure passed as the last argument to foo } or foo(1,2) [x] { //closure with one argument (x) passed as the last argument to foo print (x); } The reason why I use [args] instead of (args) is that (args) is ambigious: foo(1,2) (x) { } There is no way in this case to tell if foo expects 3 arguments (int,int,closure(x)) or if foo expects 2 arguments and returns a closure with one argument(int,int) - closure(x) So thats pretty much the reason why I use [] as for now. I could change this to something like: foo(1,2) : (x) { } or foo(1,2) (x) -> { } So the actual question is, what do you think looks best? [...] is somewhat wrist unfriendly. let x = [a,b] { } Ideas?

  • Modify .htm files on wireless router

    - by mdeitrick
    What am I trying to do? I am attempting to access the .htm files on my wireless router to modify the look and feel of the Netgear GENIE webpage(s). What have I done? I've read several articles on eHow and Instructables that detail how to setup your router as an FTP server, since I figured the best way to access the files would be through FileZilla. Setting up an FTP server through my router doesn't sound like what I should do to accomplish my task... or perhaps it is? I've also read the documents provided by Netgear for getting started and setting up functionality on the router. Maybe I overlooked something? My specifications Netgear router WNR2000v3 FileZilla v3.8.1 UPDATE: Since someone voted to close this question I'll clarify what I'm asking for... At the present I am dissatisfied with the current UI/webpage look when logging into routerlogin.net. Furthermore I would like to make changes to the admin dashboard.

  • syslog-ng fails to log on lxc host

    - by christian
    we are running CentOS 6 servers with multiple lxc-containers. For system logging we are using syslog-ng. After a while the syslog-ng daemon stops logging messages, but the daemon keeps running. This happens on the host and inside the containers (where another syslog-ng is running) as well. We could not find any patterns for the failure yet but we assume that it has something to do with lxc, because we don't have these problems on other hosts. We have the suspicion that these problems occur when more than on lxc-container is running and that only "new" processes can not log. We are running the following software versions: CentOS-Linux 6.4/6.5 lxc-0.7.5 syslog-ng-3.2.5 Do you have any ideas? Best regards trademesh

  • Is "as long as it works" the norm?

    - by q303
    Hi, My last shop did not have a process. Agile essentially meant they did not have a plan at all about how to develop or manage their projects. It meant "hey, here's a ton of work. Go do it in two weeks. We're fast paced and agile." They released stuff that they knew had problems. They didn't care how things were written. There were no code reviews--despite there being several developers. They released software they knew to be buggy. At my previous job, people had the attitude as long as it works, it's fine. When I asked for a rewrite of some code I had written while we were essentially exploring the spec, they denied it. I wanted to rewrite the code because code was repeated in multiple places, there was no encapsulation and it took people a long time to make changes to it. So essentially, my impression is this: programming boils down to the following: Reading some book about the latest tool/technology Throwing code together based on this, avoiding writing any individual code because the company doesn't want to "maintain custom code" Showing it and moving on to the next thing, "as long as it works." I've always told myself that next job I'm going to get a better shop. It never happens. If this is it, then I feel stuck. The technologies always change; if the only professional development here is reading the latest MS Press technology book, then what have you built in 10 years but a superficial knowledge of various technologies? I'm concerned about: Best way to have professional standards How to develop meaningful knowledge and experience in this situation

  • SQL – Download FREE Book – Data Access for HighlyScalable Solutions: Using SQL, NoSQL, and Polyglot Persistence

    - by Pinal Dave
    Recently I was preparing for Big Data and I ended up on very interesting read for everybody. This is created by Microsoft and it is indeed a fantastic read as per my opinion. It took me some time to read this entire book but it was worth reading this as it tried to answer two of the very interesting questions related to muscle. Here is the abstract from the book: Organizations seeking to use a NoSQL database are therefore faced with a twofold challenge: • Which NoSQL database(s) best meet(s) the needs of the organization? • How does an organization integrate a NoSQL database into its solutions? As I keep on reading the book, I find it very interesting and informative. I suggest if you have time this weekend, download the book and read it. This guide focuses on the most common types of NoSQL database currently available, describes the situations for which they are most suited, and shows examples of how you might incorporate them into a business application. The guide summarizes the experiences of a fictitious organization named Adventure Works, who implemented a solution that comprised an assortment of different databases. Download Data Access for HighlyScalable Solutions:  Using SQL, NoSQL,  and Polyglot Persistence While we are talking about Big Data and NoSQL do not forget to check out my tomorrow’s blog as I am going to talk about the same subject and it will be very interesting.

  • Capitalizing on JavaScript's prototypal inheritance

    - by keithjgrant
    JavaScript has a class-free object system in which objects inherit properties directly from other objects. This is really powerful, but it is unfamiliar to classically trained programmers. If you attempt to apply classical design patterns directly to JavaScript, you will be frustrated. But if you learn to work with JavaScript's prototypal nature, your efforts will be rewarded. ... It is Lisp in C's clothing. -Douglas Crockford What does this mean for a game developer working with canvas and HTML5? I've been looking over this question on useful design patterns in gaming, but prototypal inheritance is very different than classical inheritance, and there are surely differences in the best way to apply some of these common patterns. For example, classical inheritance allows us to create a moveableEntity class, and extend that with any classes that move in our game world (player, monster, bullet, etc.). Sure, you can strongarm JavaScript to work that way, but in doing so, you are kind of fighting against its nature. Is there a better approach to this sort of problem when we have prototypal inheritance at our fingertips?

  • Canonicals with differing content

    - by Jimbo Jonny
    Interesting conundrum here with canonicals. Lets say I have a site with a "verified" system where other websites can become so and so "verified". Their url to send people to to confirm verification is something like "blah.com/verify/company1" and "blah.com/verify/company2". But logically "blah.com/verify" itself is not verifying anyone in particular, so it redirects to the signup form to get verified, at "blah.com/verify/register" As far as the actual companies registered, I figure it doesn't make sense to index every individual url with only the tiny difference of which company name it's saying yay or nay to being verified, so canonicals could come in handy on those pages to condense the indexing. Yet making "blah.com/verify" the canonical "hub" doesn't work well because it's a signup form, not a verification page, so technically has quite different content from the various verification pages themselves. But at the same time it's a bit unfair to choose 1 company to point all the canonical benefits too to use that as the "hub", yet a bit wasteful to have google index every individual verification page and spread out all that linkjuice. Basically, I'm just looking for advice, what's best for this from a search engine standpoint?

  • Add static ARP entries when network is brought up

    - by jozzas
    I have some pretty dumb IP devices on a subnet with my Ubuntu server, and the server receives streaming data from each device. I have run into a problem in that when an ARP request is issued to the device while it is streaming data to the server, the request is ignored, the cache entry times out and the server stops receiving the stream. So, to prevent the server from sending ARP requests to these devices altogether, I would like to add a static ARP entry for each, something like arp -i eth2 -s ip.of.the.device mac:of:the:device But these "static" ARP entries are lost if networking is disabled / enabled or if the server is rebooted. Where is the best place to automatically add these entries, preferably somewhere that will re-add them every time the interface eth2 is brought up? I really don't want to have to write a script that monitors the output of arp and re-adds the cache entries if they're missing. Edit to add what my final script was: Created the file /etc/network/if-up.d/add-my-static-arp With the contents: #!/bin/sh arp -i eth0 -s 192.168.0.4 00:50:cc:44:55:55 arp -i eth0 -s 192.168.0.5 00:50:cc:44:55:56 arp -i eth0 -s 192.168.0.6 00:50:cc:44:55:57 And then obviously add the permission to allow it to be executed: chmod +x /etc/network/if-up.d/add-my-static-arp And these arp entries will be manually added or re-added every time any network interface is brought up.

When clicking this button I want to start the script redeploymyapp. This script stops the MyApp deamon, upgrades the application and starts the daemon again. The problem is, that the redeploymyapp script needs to be executed by the user myapp, while MyPortal is running as www-data. What is te best way to solve this problem?

  • JavaScript Class Patterns Revisited: Endgame

    - by Liam McLennan
    I recently described some of the patterns used to simulate classes (types) in JavaScript. But I missed the best pattern of them all. I described a pattern I called constructor function with a prototype that looks like this: function Person(name, age) { this.name = name; this.age = age; } Person.prototype = { toString: function() { return this.name + " is " + this.age + " years old."; } }; var john = new Person("John Galt", 50); console.log(john.toString()); and I mentioned that the problem with this pattern is that it does not provide any encapsulation, that is, it does not allow private variables. Jan Van Ryswyck recently posted the solution, obvious in hindsight, of wrapping the constructor function in another function, thereby allowing private variables through closure. The above example becomes: var Person = (function() { // private variables go here var name,age; function constructor(n, a) { name = n; age = a; } constructor.prototype = { toString: function() { return name + " is " + age + " years old."; } }; return constructor; })(); var john = new Person("John Galt", 50); console.log(john.toString()); Now we have prototypal inheritance and encapsulation. The important thing to understand is that the constructor, and the toString function both have access to the name and age private variables because they are in an outer scope and they become part of the closure.

  • What do I need to develop a PHP extension in lampp?

    - by Fernando Costa
    Actually I'm dealing with a trouble in my system, I have to delivery the system to clients and it was built in PHP, JS, ShellScript and SQL. I would like to encrypt the code or obfuscate it from eyes of others! Then someone from the community told me about build my own PHP extension, it sounds to me as a great idea, since it will not be with the main code of the system. But I have a problem doing this way, if a programmer get in the extensions and find it, all the hard work has gone. Then I'm here to ask again about this matter. What is the best way to hide my Business Logic from third parties? I know that has stuffs like IonCube, Zend Guard, and many others. But I'm looking something that I can build myself. Is PHP extension the right way to follow? Or some Half SaaS system, with dependencies (Business Logic) in a remote server? About the environment OS: Kernel Linux 2.6.37.1-1.2 - LAMPP (Apache 2.2, MySQL 5.5 PHP 5.3.8) In php generally the extension is located at /php/ext/ but in lampp I have no idea where it is, I just found a folder /opt/lampp/lib/php/extensions/ is that right place?

  • Z Order in 2D with orthographic projection and texture atlas

    - by Carbon Crystal
    I am working with a 2D game in OpenGL ES and have a question about z-order together with a texture atlas. I am using an orthographic projection because I want pixel-perfect rendering of 2D sprites, however from what I can determine the draw order is really the only thing that will determine which textures (sprites) appear above or below their neighbors. That is, the "z-index" is a function of the order in which the textures are drawn as opposed to the z coordinate on the vertex array being drawn. So.. I have a texture atlas to save binding multiple textures for each draw call but this immediately creates a problem if there is more than one atlas in play. If I need to draw textures from more than one atlas (typically the case if I have too many sprites to fit in a single atlas of a reasonable size), then I can't maintain a "draw order" across atlases unless I want to bind/unbind the atlas textures more than once.. which kinda defeats the purpose. Does anyone have any clues as to what the best approach is here? Currently I'm running under an assumption that I will have to declare different fixed "depths" (e.g foreground, background etc) in my 2D scene and assume that the z-order for sprites at a given depth is the same. Then I can have as many atlases as I need at each depth and simply draw the depths in order (along with their associated atlases) I'd love to hear what other people are doing.
