  • Simple problem with mod_rewrite in the Fat Free Framework

    - by ian
    I am trying to setup and learn the Fat Free Framework for PHP. http://fatfree.sourceforge.net/ It's is fairly simple to setup and I am running it on my machine using MAMP. I was able to get the 'hello world' example running just fin: require_once 'path/to/F3.php'; F3::route('GET /','home'); function home() { echo 'Hello, world!'; } F3::run(); But when I try to add in the second part, which has two routes: require_once 'F3/F3.php'; F3::route('GET /','home'); function home() { echo 'Hello, world!'; } F3::route('GET /about','about'); function about() { echo 'About Us.'; } F3::run(); I get a 404 error if I try the second URL: /about Not sure why one of the mod_rewrite commands would be working and not the other. Below is my .htaccess file: # Enable rewrite engine and route requests to framework RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-l RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php [L,QSA] # Disable ETags Header Unset ETag FileETag none # Default expires header if none specified (stay in browser cache for 7 days) <IfModule mod_expires.c> ExpiresActive On ExpiresDefault A604800 </IfModule>

  • CSS - Why is this invisible margin being applied to my <a> tag css-button?

    - by Kenny Bones
    I was having trouble with two types of buttons. It was a form button and a css button basically. And I was advised that the css button whould use display:inline-block; This made the whole a href tag actually look like a button. But this invisible margin seems to be screwing up something. I tried separating them into separate css classes, but oddly, applying a real margin to the css button gives an additional margin as well. What's causing this? You can easily see it here (low graphics): www.matkalenderen.no Basically, code looks like this: <input type="submit" value="Logg inn" class="button_blue" alt="ready to login"> <a class="button_css_red" href="access.php">Glemt passord</a> CSS .button_red, .button_blue, .button_css_red, .button_css_blue { background-image:url("../img/sprite_buttons.png"); background-repeat:no-repeat; border: none; color:#FFFFFF; display:inline-block; display:inline-block; font-size:12px; height:27px; width:98px; } .button_css_red, .button_css_blue { margin-top:20px; }

  • local vs core contoller

    - by latvian
    Hi, I am adding new column and action in the local admin app/code/local/Mage/Adminhtml/Block/Catalog/Product/Grid.php which works fine, however. The local controller/app/code/local/Mage/Adminhtml/Block/Catalog/Product.php is not being used or is not overloading the admin one /app/code/core/Mage/Adminhtml/Block/Catalog/Product.php. This is almost fresh install of Magento 1.4.0.1. I am the only one working, so i know it is not overloaded by some custom controller. I have disabled all custom modules. I have rolled back most of my changes. I have checked /etc/Modules/Mage_Catalog.xml. Refreshed cache all possible ways, loged in and out. Nothing....still using the core contoller copy. why? How do you troubleshoot, meaning, at what moment magento decides using between core or local copies? ...its even more strange because it does not parse local Adminhtml config.xml but uses local Adminthml copy of Blocks. Any pointer would help. I would like to keep everything in local code. Thank You, Margots

  • Importing a div's content from a Static HTML file using PHP or jQuery or Ajax?

    - by Vikram
    Hello friends a newbie question... The Issue is like this: I have a static HTML file and I want to import just a portion of that file into another page. How can I do that. Example Code: <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Some title here</title> <link rel="stylesheet" type="text/css" href="styles.css" /> </head> <body> <div id="box-1"> <div class="block"> <!-- Some code here --> </div> </div> <div id="box-2"> <div class="block"> <!-- Some code here --> </div> </div> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script src="script.js"></script> </body> </html> Now what I want is to read this HTML file and import just this bit: <div id="box-1"> <div class="block"> <!-- Some code here --> </div> </div> Is there a way of doing it?

  • How to call a generic method with an anonymous type involving generics?

    - by Alex Black
    I've got this code that works: def testTypeSpecialization = { class Foo[T] def add[T](obj: Foo[T]): Foo[T] = obj def addInt[X <% Foo[Int]](obj: X): X = { add(obj) obj } val foo = addInt(new Foo[Int] { def someMethod: String = "Hello world" }) assert(true) } But, I'd like to write it like this: def testTypeSpecialization = { class Foo[T] def add[X, T <% Foo[X](obj: T): T = obj val foo = add(new Foo[Int] { def someMethod: String = "Hello world" }) assert(true) } This second one fails to compile: no implicit argument matching parameter type (Foo[Int]{ ... }) = Foo[Nothing] was found. Basically: I'd like to create a new anonymous class/instance on the fly (e.g. new Foo[Int] { ... } ), and pass it into an "add" method which will add it to a list, and then return it The key thing here is that the variable from "val foo = " I'd like its type to be the anonymous class, not Foo[Int], since it adds methods (someMethod in this example) Any ideas? I think the 2nd one fails because the type Int is being erased. I can apparently 'hint' the compiler like this: def testTypeSpecialization = { class Foo[T] def add[X, T <% Foo[X]](dummy: X, obj: T): T = obj val foo = add(2, new Foo[Int] { def someMethod: String = "Hello world" }) assert(true) }

  • Centered DIV w/ width dependant on text, buffered by two divs that should fill the containing DIV

    - by Andrew Thompson
    I have been wracking my brains on this seemingly small issue the whole day. My web dev friends are baffled and I could not find a suitable answer in my search of this site and others (though, I could have missed it somewhere along the way). Here's the problem: 3 DIVS within one fixed-width container DIV The center DIV has text that will be different on other sites The center DIV needs to be centered, and no larger than the text it contains. This is what I'd like to end up with The basic HTMl: <div id="container" > <div id="left" ></div> <div id="center" >Text inside center should resize this block</div> <div id="right" ></div> </div> Below, I removed most of the styles I have tried. This CSS currently centers the DIV (if I set it as an inline block), but I need the other divs to fill the left and right space remaining: #container { width:750px; text-align:center; } #left { background-color:#E85355; } #center { background-color:#CDD7D7; display:inline-block; } #right { background-color:#65A8A6; } I've tried floating, no-wrap, overflow, etc. Thanks a million to whomever can offer some help!

  • Emacs hide/show support for C++ triple-slash Doxygen markup?

    - by jsyjr
    I use Doxygen's triple-slash syntax to markup my C++ code. There are two important cases which arise: 1) block markup comments which are the sole element on the line and may or may not begin flush left; e.g. class foo /// A one sentence brief description of foo. The elaboration can /// continue on for many lines. { ... }; void foo::bar /// A one sentence brief description of bar. The elaboration can /// continue on for many lines. () const { ... } 2) trailing markup comments which always follow some number of C++ tokens earlier on the first line but may still spill over onto subsequent lines; e.g. class foo { int _var1; ///< A brief description of _var1. int _var2; ///< A brief description of _var2 ///< requiring additional lines. } void foo::bar ( int arg1 ///< A brief description of arg1. , int arg2 ///< A brief description of arg2 ///< requiring additional lines. ) const { ... } I wonder what hide/show support exists to deal with these conventions. The most important cases are the block markup comments. Ideally I would like to be able to eliminate these altogether, meaning that I would prefer not to waste a line simply to indicate presence of a folded block markup comment. Instead I would like a fringe marker, a la http://www.emacswiki.org/emacs/hideshowvis.el /john

  • UIButton title disappears on touch

    - by psychotik
    I want a touchable UILabel, but since that's not possible I decided to create a UIButton of type UIButtonTypeCustom. It looks how I want it to look, but when I touch it, the title disappears. I tried setting the title for state UIControlStateHighlighted but that didn't help. I know I'm doing something really silly here, but can't figure it out. I tried a few things (commented in the code below) which didn't seem to help. Here's how I'm configuring the button: UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, width, height); button.clearsContextBeforeDrawing = YES; button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft; button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter; button.enabled = YES; button.hidden = NO; button.highlighted = NO; button.opaque = YES; button.selected = NO; button.userInteractionEnabled = YES; button.showsTouchWhenHighlighted = NO; [button setTitle:@"Hello World" forState:UIControlStateNormal]; button.titleLabel.font = [UIFont boldSystemFontOfSize:16]; button.titleLabel.textColor = [UIColor blackColor]; // Things I tried that didn't help //[button setBackgroundColor:[UIColor clearColor]]; //button.titleLabel.text = @"Hello World"; //[button setTitle:@"Hello World" forState:UIControlStateHighlighted]; Any ideas?

  • Event Dispatching, void pointer and alternatives

    - by PeeS
    i have my event dispatching / handling functionality working fine, but there is one issue that i need to resolve. Long story short, here are the details. // The event structure struct tEventMessage { // Type of the event int Type; // (void*) Allows those to be casted into per-Type objects void *pArgument1; void *pArgument2; }; I am sending events from different modules in my engine by using the above structure, which requires a pointer to an argument. All messages are queued, and then dispatched on the next ::Tick(). It works fine, untill i try to send something that doesn't exist in next ::Tick, for example: When a mouse click is being handled, it calculates the click coordinates in world space. This is being sent with a pointer to a vector representing that position, but after my program quits that method, this pointer gets invalid obviously, cause local CVector3 is destructed: CVector2 vScreenSpacePosition = vAt; CVector3 v3DPositionA = CVector3(0,0,0); CVector3 v3DPositionB = CVector3(0,0,0); // Screen space to World space calculation for depth zNear v3DPositionA = CMath::UnProject(vScreenSpacePosition, m_vScreenSize, m_Level.GetCurrentCamera()->getViewMatrix(), m_Level.GetCurrentCamera()->getProjectionMatrix(), -1.0 ); // Screen space to World space calculation for depth zFar v3DPositionB = CMath::UnProject(vScreenSpacePosition, m_vScreenSize, m_Level.GetCurrentCamera()->getViewMatrix(), m_Level.GetCurrentCamera()->getProjectionMatrix(), 1.0); // Send zFar position and ScreenSpace position to the handlers // Obviously both vectors won't be valid after this method quits.. CEventDispatcher::Get()->SendEvent(CIEventHandler::EVENT_SYSTEM_FINGER_DOWN, static_cast<void*>(&v3DPositionB), static_cast<void*>(&vScreenSpacePosition)); What i want to ask is, if there is any chance i could make my tEventMessage more 'template', so i can handle sending objects like in the above situation + use what is already implemented? Can't figure it out at the moment.. What else can be done here to allow me to pass some locally available data ? Please can somebody shed a bit of light on this please?

  • Multithreading: Read from / write to a pipe

    - by Tero Jokinen
    I write some data to a pipe - possibly lots of data and at random intervals. How to read the data from the pipe? Is this ok: in the main thread (current process) create two more threads (2, 3) the second thread writes sometimes to the pipe (and flush-es the pipe?) the 3rd thread has infinite loop which reads the pipe (and then sleeps for some time) Is this so far correct? Now, there are a few thing I don't understand: do I have to lock (mutex?) the pipe on write? IIRC, when writing to pipe and its buffer gets full, the write end will block until I read the already written data, right? How to check for read data in the pipe, not too often, not too rarely? So that the second thread wont block? Is there something like select for pipes? It is possible to set the pipe to unbuffered more or I have to flush it regularly - which one is better? Should I create one more thread, just for flushing the pipe after write? Because flush blocks as well, when the buffer is full, right? I just don't want the 1st and 2nd thread to block.... [Edit] Sorry, I thought the question is platform agnostic but just in case: I'm looking at this from Win32 perspective, possibly MinGW C...

  • iPhone AES encryption issue

  • Google Doclist API : bug in revision history?

    - by Jerbome
    I'm trying to manage revisions of files (not documents) stored in google docs programatically using gdata document list java library v3. I can create files and revisions using this tool : I can see them in the web UI. The thing is : the content of my revisions seems wrong. Here is my test protocol : I create a plain text file with "Hello World" in it. I upload it to gdocs without converting it. I create a revision of this file, its content changing to "Content of the second version" I create another revision, its content is now "Content of the third version" At each step, I check the content of each revision, using my app AND using the web UI. Here is what I get : First step : no problem i see one version containing the "Hello world" text Second step : no problem either, i see 2 versions, containing Hello World for the first one and Content of the second version for the second. Third step : here the problems comes. I see my 3 versions, but only the third and last seems to be correct. when i download the second version, the content is "Content of the second versio" (not a typo, it misses the 'n'). And i cannot even download the initial version, it seems to timeout. Important thing : I did not have this problem three weeks ago, my revision management worked well. I have no idea of what happens there, except it seems to be server-related, as the problem is seen either with my app or the google native webapp. Last thing : I tried using the google drive API as gdocs had been merged with drive. When i request revisions of my file, the API returns me an error saying that revisions are not supported for files, even if i can see them in the UI. I tried on converted documents, it worked. I'm looking for a workaround for this problem. Has anyone ever encountered such a problem ? Thanks in advance, Jérôme

    Im trying to navigate an XML block similar to this one ($doc) using PHP simplexml_load_string and using xpath on $doc to get only the 'Day' block like this: $myday = $doc->xpath ('//Day'); that lets me access all data from the block as an object, meaning $doc-AdultCount returns 1 and $doc-Id returns "6a0" however I can't access "SpecialDeals" content not using: $doc-SpecialDeals nor using: $doc-SpecialDeals-a:string Whats is the right syntax in this case?

  • PHP PDO Parameters from a function returned array

    - by noko
    I've got a function written that runs a query based on parameters passed to the function. I can't seem to figure out why doing the following returns a result: function test($function_returned_array) { $variable = 'Hello World'; $sql = 'SELECT `name`, `pid` FROM `products` WHERE `name` IN (?)'; $found = $this->db->get_array($sql, $variable); } While this doesn't return any results: function test2($function_returned_array) { $sql = 'SELECT `name`, `pid` FROM `products` WHERE `name` IN (?)'; $found = $this->db->get_array($sql, $function_returned_array[0]); } $function_returned_array[0] is also equal to 'Hello World'. Shouldn't they both return the same results? When I echo the values of $variable and $function_returned_array[0], they are both 'Hello World' Here's the relevant parts of my PDO wrapper: public function query(&$query, $params) { $sth = $this->_db->prepare($query); if(is_null($params)) { $sth->execute(); } else if(is_array($params)) { $sth->execute($params); } else { $sth->execute(array($params)); } $this->_rows = $sth->rowCount(); $this->_counter++; return $sth; } public function get_array(&$query, $params, $style = PDO::FETCH_ASSOC) { $q = $this->query($query, $params); return $q->fetchAll($style); } I'm using PHP 5.3.5. Any help would be appreciated.

  • Forcing size of a complex Flash object.

    - by John
    As I've found recently, setting width/height properties on a Sprite only forces the Sprite to fit the given dimensions by scaling the actual size, which is calculated by Flash based on the rendered content. This leaves me confused. If I have a custom Sprite subclass which draws using Graphics, how can I do layout before an initial render - the size will be zero until it is first drawn? For a more complex issue, let's say I have a 2D game world with objects spread over a wide area with world coordinates from (0,0) to (5000,5000), where each object has a size of maybe up to 100x100. I want to have a Flash component which is the "game window", and has a fixed size like 400x300, rendering part of the game world. So how do I force the game window size to 400x300 pixels? I can draw a 400x300 rectangle to get the size correct but then if I draw any objects which are partly in-view, they can screw this up. Is the right approach to provide a custom setSize(w,h) method which is used rather than width & height setters? But even so, is there no way to make a Sprite force to the size I want? Do you really have to catch it every render and re-scale it?

  • Unordered list appears higher than div

    I am trying to create a simple page, which I normally can without any trouble. However, the unordered list appears higher up the page than the div. I do know a solution for this, however I cannot remember it. The page goes like this: <style> ul.menu { list-style-type: none; margin:150; margin-bottom:30px; padding:0; display: block; width: 708px; margin-left: auto; margin-right: auto; } li.menu { float:left; display: block; width: 118px; } a.menu:link,a.menu:visited { color:black; display:block; border:1px solid black; background-color:#FFFF00; width:118px; text-align:center; text-decoration:none; font-family:"Courier New", Courier, monospace } a.menu:hover { background-color:#FFBB11; } </style> <div id="head"> My images here & such</div> <ul class="menu"> <li class="menu"> <a class="menu">Main</a> </li> </ul> Normally I welcome suggestions to change my code, but I have a deadline today!

  • Trouble understanding the semantics of volatile in Java

    - by HungryTux
    I've been reading up about the use of volatile variables in Java. I understand that they ensure instant visibility of their latest updates to all the threads running in the system on different cores/processors. However no atomicity of the operations that caused these updates is ensured. I see the following literature being used frequently A write to a volatile field happens-before every read of that same field . This is where I am a little confused. Here's a snippet of code which should help me better explain my query. volatile int x = 0; volatile int y = 0; Thread-0: | Thread-1: | if (x==1) { | if (y==1) { return false; | return false; } else { | } else { y=1; | x=1; return true; | return true; } | } Since x & y are both volatile, we have the following happens-before edges between the write of y in Thread-0 and read of y in Thread-1 between the write of x in Thread-1 and read of x in Thread-0 Does this imply that, at any point of time, only one of the threads can be in its 'else' block(since a write would happen before the read)? It may well be possible that Thread-0 starts, loads x, finds it value as 0 and right before it is about to write y in the else-block, there's a context switch to Thread-1 which loads y finds it value as 0 and thus enters the else-block too. Does volatile guard against such context switches (seems very unlikely)?

  • Prevent RDP logon brute force in mikrotik router via winbox

    - by holian
    Masters, I need help, how to config our router to block RDP brute force attacks I would like to set our router to only allow RDP connection from a specified country (our specified IP ranges), plus i need to set up router to block (take ips to black list) and drop brute force attepmst to specified port numbers. I try to set this with changeing the ftp port to rdp port. http://wiki.mikrotik.com/wiki/Bruteforce_login_prevention_%28FTP_%26_SSH Any suggestion tnx. H Current configuration: I try to configure the router via Winbox. I set some NAT rules (from dyndns to local address, rdp port) In the filter rules tab: I'm not sure this configuration should do the trick?! Is the content text "530 login incorrect" is fit for RDP connection to? Because in the tutorial used for filtering FTP connection. How to set router to allow RDP attempts from specified IP ranges? Thank you // New config

  • LVM mirror attempt results in "Insufficient free space"

    - by MattK
    Attempting to add a disk to mirror an LVM volume on CentOS 7 always fails with "Insufficient free space: 1 extents needed, but only 0 available". Having searched for a solution, I have tried specifying disks, multiple logging options, adding 3rd log partition, but have not found a solution Not sure if I am making a rookie mistake, or there is something more subtle wrong (I am more familiar with ZFS, new to using LVM): # lvconvert -m1 centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --mirrorlog mirrored --alloc anywhere centos_bi/home /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home /dev/sdi2 /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available The two disks are of the same size, and have identical partition layouts via "sfdisk -d /dev/sdi part_table; sfdisk /dev/sda < part_table". The current configuration is detailed below. # pvs PV VG Fmt Attr PSize PFree /dev/sda1 centos_bi lvm2 a-- 496.00m 496.00m /dev/sda2 centos_bi lvm2 a-- 465.27g 465.27g /dev/sdi2 centos_bi lvm2 a-- 465.27g 0 # vgs VG #PV #LV #SN Attr VSize VFree centos_bi 3 3 0 wz--n- 931.02g 465.75g # lvs -a -o +devices LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert Devices home centos_bi -wi-ao---- 391.64g /dev/sdi2(6050) root centos_bi -wi-ao---- 50.00g /dev/sdi2(106309) swap centos_bi -wi-ao---- 23.63g /dev/sdi2(0) # pvdisplay --- Physical volume --- PV Name /dev/sdi2 VG Name centos_bi PV Size 465.27 GiB / not usable 3.00 MiB Allocatable yes (but full) PE Size 4.00 MiB Total PE 119109 Free PE 0 Allocated PE 119109 --- Physical volume --- PV Name /dev/sda2 VG Name centos_bi PV Size 465.27 GiB / not usable 3.00 MiB Allocatable yes PE Size 4.00 MiB Total PE 119109 Free PE 119109 Allocated PE 0 --- Physical volume --- PV Name /dev/sda1 VG Name centos_bi PV Size 500.00 MiB / not usable 4.00 MiB Allocatable yes PE Size 4.00 MiB Total PE 124 Free PE 124 Allocated PE 0 # vgdisplay --- Volume group --- VG Name centos_bi System ID Format lvm2 Metadata Areas 3 Metadata Sequence No 10 VG Access read/write VG Status resizable MAX LV 0 Cur LV 3 Open LV 3 Max PV 0 Cur PV 3 Act PV 3 VG Size 931.02 GiB PE Size 4.00 MiB Total PE 238342 Alloc PE / Size 119109 / 465.27 GiB Free PE / Size 119233 / 465.75 GiB # lvdisplay --- Logical volume --- LV Path /dev/centos_bi/swap LV Name swap VG Name centos_bi LV Write Access read/write LV Creation host, time localhost, 2014-08-07 16:34:34 -0400 LV Status available # open 2 LV Size 23.63 GiB Current LE 6050 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:1 --- Logical volume --- LV Path /dev/centos_bi/home LV Name home VG Name centos_bi LV Write Access read/write LV Creation host, time localhost, 2014-08-07 16:34:35 -0400 LV Status available # open 1 LV Size 391.64 GiB Current LE 100259 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2 --- Logical volume --- LV Path /dev/centos_bi/root LV Name root VG Name centos_bi LV Write Access read/write LV Creation host, time localhost, 2014-08-07 16:34:37 -0400 LV Status available # open 1 LV Size 50.00 GiB Current LE 12800 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:0
