• Block specific IP block from my website in PHP

  - by iTayb

  I'd like, for example, block every IP from base 89.95 (89.95..). I don't have .htaccess files on my server, so I'll have to do it with PHP. if ($_SERVER['REMOTE_ADDR'] == "89.95.25.37") die(); Would block specific IP. How can I block entire IP blocks? Thank you very much.

• Access block level storage via kernel

  - by N 1.1

  How to access block level storage via the kernel (w/o using scsi libraries)? My intent is to implement a block level storage protocol over network for learning purpose, almost the same way SCSI works. Requests will be generated by initiator and sent to target (both userspace program) which makes call to kernel module and returns the data using TCP protocol to initiator. So far, I have managed to build a simple "Hello" module and run it (I am new at kernel programming), but unable to proceed with block access. After searching a lot, I found struct buffer_head * bread(int dev,int block) in linux/fs.h, but the compiler throws error. error: implicit declaration of function ‘bread’ Please help, also feel free to advice on starting with kernel programming. Thank you!

• HowTo check whether Exception Block is available for the main PLSQL block or routine

  - by user1297211

  I am trying to think of a validator that checks for Exception block available in PL/SQL block or any routine for the main body ( Highlighted in Bold). Eg : DECLARE some data Procedure xyx IS BEGIN .... EXCEPTION .. END; BEGIN some data BEGIN .... EXCEPTION .. END; **EXCEPTION** some data BEGIN .... EXCEPTION .. END; END; This is a simple example there can be many other scenarios but my need id to find that Exception block is avaialble for the main block of PL/SQL code. Please let me know if you have any suggestion. Thanks

• block certain websites from browser

  - by phunehehe

  Hello there, A friend of mine (who is not a geek) asks me how to stop her little brother from playing web games on her computer. She is currently using Chrome and IE, and I have never done that before, even on FF. I would prefer a solution that is simple and does not require additional applications. Although it seems unlikely, is there a solution that works for all browsers (i.e. do it once and I never have to fix it for a new browser)? Thanks.

• Block p2p downloading in my office?

  - by Andrew

  I work in an education office in a third world country. We pay for internet by the megabyte (no other choice) and have lately been using an incredible amount of bandwidth. This is because the office staff have found out about p2p sharing. As far as I know, Limewire is the only program they're using, but I'm sure it's just a matter of time before they discover the more general world of bittorrent. Using only a linksys router (that I could flash), is there any way for me prevent the office from destroying our bandwidth cap by downloading personal items (against policy). Even semi-fixes would be better than nothing.

• iptables to block non-VPN-traffic if not through tun0

  - by dacrow

  I have a dedicated Webserver running Debian 6 and some Apache, Tomcat, Asterisk and Mail-stuff. Now we needed to add VPN support for a special program. We installed OpenVPN and registered with a VPN provider. The connection works well and we have a virtual tun0 interface for tunneling. To archive the goal for only tunneling a single program through VPN, we start the program with sudo -u username -g groupname command and added a iptables rule to mark all traffic coming from groupname iptables -t mangle -A OUTPUT -m owner --gid-owner groupname -j MARK --set-mark 42 Afterwards we tell iptables to to some SNAT and tell ip route to use special routing table for marked traffic packets. Problem: if the VPN failes, there is a chance that the special to-be-tunneled program communicates over the normal eth0 interface. Desired solution: All marked traffic should not be allowed to go directly through eth0, it has to go through tun0 first. I tried the following commands which didn't work: iptables -A OUTPUT -m owner --gid-owner groupname ! -o tun0 -j REJECT iptables -A OUTPUT -m owner --gid-owner groupname -o eth0 -j REJECT It might be the problem, that the above iptable-rules didn't work due to the fact, that the packets are first marked, then put into tun0 and then transmitted by eth0 while they are still marked.. I don't know how to de-mark them after in tun0 or to tell iptables, that all marked packet may pass eth0, if they where in tun0 before or if they going to the gateway of my VPN provider. Does someone has any idea to a solution?

• Deep Cloning C++ class that inherits CCNode in Cocos2dx

  - by A Devanney

  I stuck with something in Cocos2dx ... I'm trying to deep clone one of my classes that inherits CCNode. Basically i have.... GameItem* pTemp = new GameItem(*_actualItem); // loops through all the blocks in gameitem and updates their position pTemp->moveDown(); // if in boundary or collision etc... if (_gameBoard->isValidMove(pTemp)) { _actualItem = pTemp; // display the position CCLog("pos (1) --- (X : %d,Y : %d)", _actualItem->getGridX(),_actualItem->getGridY()); } Then doesn't work, because the gameitem inherits CCNode and has the collection of another class that also inherits CCNode. its just creating a shallow copy and when you look at children of the gameitem node in the copy, just point to the original? class GameItem : public CCNode { // maps to the actual grid position of the shape CCPoint* _rawPosition; // tracks the current grid position int _gridX, _gridY; // tracks the change if the item has moved CCPoint _offset; public: //constructors GameItem& operator=(const GameItem& item); GameItem(Shape shape); ... } then in the implementation.... GameItem& GameItem::operator=(const GameItem& item) { _gridX = item.getGridX(); _gridY = item.getGridY(); _offset = item.getOffSet(); _rawPosition = item.getRawPosition(); // how do i copy the node? return *this; } // shape contains an array of position for the game character GameItem::GameItem(Shape shape) { _rawPosition = shape.getShapePositions(); //loop through all blocks in position for (int i = 0; i < 7; i++) { // get the position of the first block in the shape and add to the position of the first block int x = (int) (getRawPosition()[i].x + getGridX()); int y = (int) (getRawPosition()[i].y + getGridY()); //instantiate a block with the position and type Block* block = Block::blockWithFile(x,y,(i+1), shape); // add the block to the this node this->addChild(block); } } And for clarity here is the block class class Block : public CCNode{ private: // using composition over inheritance CCSprite* _sprite; // tracks the current grid position int _gridX, _gridY; // used to store actual image number int _blockNo; public: Block(void); Block(int gridX, int gridY, int blockNo); Block& operator=(const Block& block); // static constructor for the creation of a block static Block* blockWithFile(int gridX, int gridY,int blockNo, Shape shape); ... } The blocks implementation..... Block& Block::operator=(const Block& block) { _sprite = new CCSprite(*block._sprite); _gridX = block._gridX; _gridY = block._gridY; _blockNo = block._blockNo; //again how to clone CCNode? return *this; } Block* Block::blockWithFile(int gridX, int gridY,int blockNo, Shape shape) { Block* block = new Block(); if (block && block->initBlockWithFile(gridX, gridY,blockNo, shape)) { block->autorelease(); return block; } CC_SAFE_DELETE(block); return NULL; } bool Block::initBlockWithFile(int gridX, int gridY,int blockNo, Shape shape) { setGridX(gridX); setGridY(gridY); setBlockNo(blockNo); const char* characterImg = helperFunctions::Format(shape.getFileName(),blockNo); // add to the spritesheet CCTexture2D* gameArtTexture = CCTextureCache::sharedTextureCache()->addImage("Character.pvr.ccz"); CCSpriteBatchNode::createWithTexture(gameArtTexture); // block settings _sprite = CCSprite::createWithSpriteFrameName(characterImg); // set the position of the block and add it to the layer this->setPosition(CONVERTGRIDTOACTUALPOS_X_Y(gridX,gridY)); this->addChild(_sprite); return true; } Any ideas are welcome at this point!! thanks

  I am working with v4 of the Enterprise Application block and I am trying to learn how to access the Application Settings that I have added using the Enterprise Library Configuration tool. It's as if the code does not recognize the settings even though I can see them in the app.config. I DO have a Settings.Settings designer added and I CAN get to those settings the standard way even though the settings added in that designer do NOT show up in the app.config like they normally would if I am NOT using the Enterprise Block How do I access the App Settings that I added with the Enterprise Block?

• Centering An Inline-Block DIV

  - by Aaron Brewer

  Does anybody know how to center align a DIV that has the display set to inline-block? I cannot set the display to block because I have a background image that needs to be repeated, and it needs to expand based on the content. It sits inside of a parent div, in which is larger when it comes to width. So all in all. Does anyone have a fix to center align a div with the display set to inline-block? And no, text-align: center; does not work, nor does margin: 0 auto; jsFiddle: http://jsfiddle.net/HkvzM/ Thank you!

• Switching my collision detection to array lists caused it to stop working

  - by Charlton Santana

  I have made a collision detection system which worked when I did not use array list and block generation. It is weird why it's not working but here's the code, and if anyone could help I would be very grateful :) The first code if the block generation. private static final List<Block> BLOCKS = new ArrayList<Block>(); Random rnd = new Random(System.currentTimeMillis()); int randomx = 400; int randomy = 400; int blocknum = 100; String Title = "blocktitle" + blocknum; private Block block; public void generateBlocks(){ if(blocknum > 0){ int offset = rnd.nextInt(250) + 100; //500 is the maximum offset, this is a constant randomx += offset;//ofset will be between 100 and 400 int randomyoff = rnd.nextInt(80); //500 is the maximum offset, this is a constant randomy = platformheighttwo - 6 - randomyoff;//ofset will be between 100 and 400 block = new Block(BitmapFactory.decodeResource(getResources(), R.drawable.block2), randomx, randomy); BLOCKS.add(block); blocknum -= 1; } The second is where the collision detection takes place note: the block.draw(canvas); works perfectly. It's the blocks that don't work. for(Block block : BLOCKS) { block.draw(canvas); if (sprite.bottomrx < block.bottomrx && sprite.bottomrx > block.bottomlx && sprite.bottomry < block.bottommy && sprite.bottomry > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } // bottom left touching block? if (sprite.bottomlx < block.bottomrx && sprite.bottomlx > block.bottomlx && sprite.bottomly < block.bottommy && sprite.bottomly > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } // top right touching block? if (sprite.toprx < block.bottomrx && sprite.toprx > block.bottomlx && sprite.topry < block.bottommy && sprite.topry > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } //top left touching block? if (sprite.toprx < block.bottomrx && sprite.toprx > block.bottomlx && sprite.topry < block.bottommy && sprite.topry > block.topry ){ Log.d(TAG, "Collided!!!!!!!!!!!!1"); } } The values eg bottomrx are in the block.java file..

• Stretching width correctly to 100% of an inline-block element in IE6 and IE7

  - by Simon Lieschke

  I have the following markup, where I am attempting to get the right hand side of the second table to align with the right hand side of the heading above it. This works in IE8, Firefox and Chrome, but in IE6/7 the table is incorrectly stretched to fill the width of the page. I'm using the Trip Switch hasLayout trigger to apply inline-block in IE6/7. Does anyone know how (or even if) I can get the table only to fill the natural width of the wrapper element displayed with inline-block in IE6/7? You can see the code running live at http://jsbin.com/uyuva. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <style> .wrapper { display: inline-block; border: 1px solid green; } /* display: inline-block triggers the wrapper element to have layout for IE 6/7. The trip switch then provides the inline component of the display behaviour. See http://www.brunildo.org/test/InlineBlockLayout.html for more details. */ .wrapper { *display: inline; } table { border: 1px solid red; } </style> </head> <body> <h1>No width on table:</h1> <div class="wrapper"> <h2>The right hand side of the table doesn't stretch to the end of this heading</h2> <table><tr><td>foo</td></tr></table> </div> text <h1>Width on table:</h1> <div class="wrapper"> <h2>The right hand side of the table should stretch to the end of this heading</h2> <table style="width: 100%"><tr><td>foo</td></tr></table> </div> text </body> </html>

• Drupal: assign block to a specific content type

  I made a customized template called node-mynode.tpl.php Whenever a node of type mynode is requested, then node-mynode.tpl.php is automatically used. However, now user wants to see a specific menu block in this case. Question: How can I assign a block to a specific content type? Hint: I have started to look at URL aliases with Pathauto. I suspect one solution may lie in this direction.

• How to calculate the maximum block length in C of a binary number

  - by user1664272

  I want to reiterate the fact that I am not asking for direct code to my problem rather than wanting information on how to reach that solution. I asked a problem earlier about counting specific integers in binary code. Now I would like to ask how one comes about counting the maximum block length within binary code. I honestly just want to know where to get started and what exactly the question means by writing code to figure out the "Maximum block length" of an inputted integers binary representation. Ex: Input 456 Output: 111001000 Number of 1's: 4 Maximum Block Length: ? Here is my code so far for reference if you need to see where I'm coming from. #include <stdio.h> int main(void) { int integer; // number to be entered by user int i, b, n; unsigned int ones; printf("Please type in a decimal integer\n"); // prompt fflush(stdout); scanf("%d", &integer); // read an integer if(integer < 0) { printf("Input value is negative!"); // if integer is less than fflush(stdout); return; // zero, print statement } else{ printf("Binary Representation:\n", integer); fflush(stdout);} //if integer is greater than zero, print statement for(i = 31; i >= 0; --i) //code to convert inputted integer to binary form { b = integer >> i; if(b&1){ printf("1"); fflush(stdout); } else{ printf("0"); fflush(stdout); } } printf("\n"); fflush(stdout); ones = 0; //empty value to store how many 1's are in binary code while(integer) //while loop to count number of 1's within binary code { ++ones; integer &= integer - 1; } printf("Number of 1's in Binary Representation: %d\n", ones); // prints number fflush(stdout); //of ones in binary code printf("Maximum Block Length: \n"); fflush(stdout); printf("\n"); fflush(stdout); return 0; }//end function main

• Fast block placement algorithm, advice needed?

  - by James Morris

  I need to emulate the window placement strategy of the Fluxbox window manager. As a rough guide, visualize randomly sized windows filling up the screen one at a time, where the rough size of each results in an average of 80 windows on screen without any window overlapping another. It is important to note that windows will close and the space that closed windows previously occupied becomes available once more for the placement of new windows. The window placement strategy has three binary options: Windows build horizontal rows or vertical columns (potentially) Windows are placed from left to right or right to left Windows are placed from top to bottom or bottom to top Why is the algorithm a problem? It needs to operate to the deadlines of a real time thread in an audio application. At this moment I am only concerned with getting a fast algorithm, don't concern yourself over the implications of real time threads and all the hurdles in programming that that brings. So far I have two choices which I have built loose prototypes for: 1) A port of the Fluxbox placement algorithm into my code. The problem with this is, the client (my program) gets kicked out of the audio server (JACK) when I try placing the worst case scenario of 256 blocks using the algorithm. This algorithm performs over 14000 full (linear) scans of the list of blocks already placed when placing the 256th window. 2) My alternative approach. Only partially implemented, this approach uses a data structure for each area of rectangular free unused space (the list of windows can be entirely separate, and is not required for testing of this algorithm). The data structure acts as a node in a doubly linked list (with sorted insertion), as well as containing the coordinates of the top-left corner, and the width and height. Furthermore, each block data structure also contains four links which connect to each immediately adjacent (touching) block on each of the four sides. IMPORTANT RULE: Each block may only touch with one block per side. The problem with this approach is, it's very complex. I have implemented the straightforward cases where 1) space is removed from one corner of a block, 2) splitting neighbouring blocks so that the IMPORTANT RULE is adhered to. The less straightforward case, where the space to be removed can only be found within a column or row of boxes, is only partially implemented - if one of the blocks to be removed is an exact fit for width (ie column) or height (ie row) then problems occur. And don't even mention the fact this only checks columns one box wide, and rows one box tall. I've implemented this algorithm in C - the language I am using for this project (I've not used C++ for a few years and am uncomfortable using it after having focused all my attention to C development, it's a hobby). The implementation is 700+ lines of code (including plenty of blank lines, brace lines, comments etc). The implementation only works for the horizontal-rows + left-right + top-bottom placement strategy. So I've either got to add some way of making this +700 lines of code work for the other 7 placement strategy options, or I'm going to have to duplicate those +700 lines of code for the other seven options. Neither of these is attractive, the first, because the existing code is complex enough, the second, because of bloat. The algorithm is not even at a stage where I can use it in the real time worst case scenario, because of missing functionality, so I still don't know if it actually performs better or worse than the first approach. What else is there? I've skimmed over and discounted: Bin Packing algorithms: their emphasis on optimal fit does not match the requirements of this algorithm. Recursive Bisection Placement algorithms: sounds promising, but these are for circuit design. Their emphasis is optimal wire length. Both of these, especially the latter, all elements to be placed/packs are known before the algorithm begins. I need an algorithm which works accumulatively with what it is given to do when it is told to do it. What are your thoughts on this? How would you approach it? What other algorithms should I look at? Or even what concepts should I research seeing as I've not studied computer science/software engineering? Please ask questions in comments if further information is needed. [edit] If it makes any difference, the units for the coordinates will not be pixels. The units are unimportant, but the grid where windows/blocks/whatever can be placed will be 127 x 127 units.

• Why use a do-end block in Lua?

  - by Mayron

  I keep trying to find answers for this but fail to do so. I wanted to know, what is the do-end block actually used for? It just says values are used when needed in my book so how could I use this? Do I use it to reduce the scope of local variables by placing a function in a do-end loop and place local variables outside of the function but inside this do-end block and the variables will be seen by the function? But then can the function still be called? Sorry for being very vague. I hope that makes sense. Maybe an illustrated example might be useful ^^

  - by Camilo Martin

  Sometimes I do this and I've seen others doing it too: VB: Try DontWannaCatchIt() Catch End Try C#: try { DontWannaCatchIt(); } catch {} I know I should catch every important exception and do something about it, but sometimes it's not important to - or am I doing something wrong? Is this usage of the try block incorrect, and the requirement of at least one catch or finally block an indication of it?
