  • What Conferences would you recommend for a UI / Frontend Web Developer in the next 6 months?

    - by rsturim
    Hello, I'm looking for a strong conference(s) to attend in the next 6 months. I may be able to attend one or two. I'm looking for something surrounding Frontend Web Development -- web standards, CSS3, html5, javascript, UX, and usability are strong interests of mine. I'm also starting to consider diving deep into designing for Mobile devices. I've discovered these 2 conferences so far -- they look very good -- but am I missing anything HUGE and/or obvious? An Event Apart - Wash DC (http://aneventapart.com/2010/dc/) Web Directions North - Altanta (http://north.webdirections.org/) Thoughts?

  • Open Source CMS with linked sub-sections and users

    - by Teegijee
    I work at a small college that wants to make "sites" for all of the academic departments (~30). I managed to talk them out of their original idea: 30 individual Wordpress installations. What a maintenance nightmare! What I'm looking for is a CMS (preferably Python or PHP, as those are my areas of expertise) that can automagically create a subsection (or subsite, whatever the appropriate vernacular) complete with user and a couple of headings based on a template. So, I could just click a button and have a new subsection for a new department complete with its own authorized user, and default subsection headings/menu/pages. Is this just wishful thinking? I don't mind getting my hands dirty (this would be the whole of my job duties), so what platform would be a good starting point for something like this? Open source is a must for me as I have literally no budget, and I'm probably going to have to dig pretty deep into the application.

  • University Assignment: Datacenter/Networking Infrastructure for Hosting Company [closed]

    - by TCB13
    My university assigned me to theorizing a data center for an Web Hosting company. The company should provide the following services: Shared WebHosting; Dedicated Servers; VPS (Virtual Private Server); The bandwith (as resquested) is limited to 10 Gbps. Is there any good book / other info I can read (max 100 pages) about how to design a good data center for hosting, what are the best practices and what should be done from a (logical) network perspective, what security policies should be implemented and how the data center should be built (physically)? Thank you ;)

  • GCC/XCode equivalent of _CrtCheckMemory?

    - by Chris Becke
    When dealing with random memory overwrites, in MSVC it is possible to validate the state of the heap at various points with a call to _CrtCheckMemory, and know with at least a small level of confidence that the code up until the check was not responsible for any errors that might cause new or malloc to fail later. In XCode, whats the equivalent way to try and box in a memory overwrite? All I have at the moment is a random failure of a call to new, somewhere deep in the bowels of some code with no real idea of how long the code has been running with a corrupt heap up until that point.

  • Recommended resource to understand Internet conventions IPs, CNAMES, *, MX etc

    - by Petras
    I am a programmer who has been creating websites for many years in shared hosting environments. To make the website live, I logged into where the domain was hosted and updated the name servers. Sometimes I didn’t want POP email so I changed an A record. I never really understood what this meant but it worked. Now we have a dedicated server and I have to fill out all this to make it live: Plus I was told I had to complete zones at my domain host: I would really like to know what all this means. What is a * record What is an @ How does the internet work regarding all these conventions? Is there a good approachable book on this topic?

  • How do I temporarily monkey with a global module constant?

    - by Daniel
    Greetings, I want to tinker with the global memcache object, and I found the following problems. Cache is a constant Cache is a module I only want to modify the behavior of Cache globally for a small section of code for a possible major performance gain. Since Cache is a module, I can't re-assign it, or encapsulate it. I Would Like To Do This: Deep in a controller method... code code code... old_cache = Cache Cache = MyCache.new code code code... Cache = old_cache code code code... However, since Cache is a constant I'm forbidden to change it. Threading is not an issue at the moment. :) Would it be "good manners" for me to just alias_method the special code I need just for a small section of code and then later unalias it again? That doesn't pass the smell test IMHO. Does anyone have any ideas? TIA, -daniel

  • Copying a Polymorphic object in C++

    - by doron
    I have base-class Base from which is derived Derived1, Derived2 and Derived3. I have constructed an instance for one of the the derived classes which I store as Base* a. I now need to make a deep copy of the object which I will store as Base* b. As far as I know, the normal way of copying a class is to use copy constructors and to overload operator=. However since I don't know whether a is of type Derived1, Derived2 or Derived3, I cannot think of a way of using either the copy constructor or operator=. The only way I can think of to cleanly make this work is to implement something like: class Base { public: virtual Base* Clone() = 0; }; and the implement Clone in in the derived class as in: class Derivedn : public Base { public: Base* Clone() { Derived1* ret = new Derived1; copy all the data members } }; Java tends to use Clone quite a bit is there more of a C++ way of doing this?

  • Why do LCD screens need a backlight? (seriously)

    - by Tudor
    Bare with me on this, I'm well aware that most LCDs have backlights. But what if, they DIDN'T? I spend long hours in front of a screen and I hate the concept of staring into a lightbulb all the time and my eyes getting sore. I need to get a new lcd (some sort of IPS that doesn't cost a fortune) soon, but no matter what I'll get, I'll still be looking at a damn light. How come you can read on a kindle w/o a backlight but there aren't any monitors like that? I mean, ideally, a screen should be like a book or any other object in real life. Just for curiosity's sake, does anyone know of any new monitor concepts? Also, http://www.indiaonrent.com/view/l/laptop-transparent-monitor.html hah!

    - by black sensei
    I've installed netbeans which comes with glassfish. i just got a book about glassfish and i wanted to try.the first surprise is the time it took to the admin page to load. i've found on serverfault and by googling that the server is making call to external resource on the network on online (not sure about that). but the adding of the java options didn't speed up the loading of the admin page. how to work around it? i've heard so good about glassfish that this leaves me perplexed. thanks for reading and for helping.

  • Given a Member Access lambda expression, convert it to a specific string representation with full ac

    - by Nathan
    Given an Expression<Func<T, object>> (e.g. x = x.Prop1.SubProp), I want to create a string "Prop1.SubProp" for as deep as necessary. In the case of a single access (e.g. x = x.Prop1), I can easily do this with: MemberExpression body = (expression.Body.NodeType == ExpressionType.Convert) ? (MemberExpression)((UnaryExpression)expression.Body).Operand : (MemberExpression)expression.Body; return body.Member.Name; However, if there is deeper nesting, e.g. x = x.Prop1.SubProp1, this only gets the most deeply nested name, e.g. "SubProp1" instead of "Prop1.SubProp1" Is there anyway to access the full property path of a lambda expression?

  • RewriteRule being greedy

    - by lardlad
    I have been looking for an answer for a few hours now, so sorry if this was asked a ton of times, I missed it. I basically want to make a rewrite to ignore the first directory. That first dir in the path will be different so I thought I could use a regex. But my regex is matching all the way to the file name: RewriteRule ^([a-z]+)?/(.+)$ $2 [L] this works if I am one level deep: http://test.domain.com/one/index.php I get the actual index page of the root. Which is what I want. but if I were to go deeper: http://test.domain.com/one/two/index.php I get a message saying /index.php was not found. So it seems my regex is not stopping after the last [a-z]. I appreciate any help. This is Apache2 if that matters at all.

  • 1 iPhone, 2 (potentially 3) Macs......& Google Apps Sync?!

    - by Goober
    Currently I use a beast of a G5 Mac at work for all my software/web development, an iMac G5 at home for personal use & a MacBook Pro for when i'm on the go. At work we make heavy use of all the Google Apps features such as calendar & docs etc. We all have an address book (local mac application) that gets synced with a list of contacts stored on our mail server. I want to be able to integrate the Google Apps calendar with my iPhone calendar (or even just iCal - which i can then sync to the iPhone). Essentially I want all three Macs to have the Google calendar synced to their version of iCal including the iPhone. I've heard that Google Sync handles something along these lines but i'm unsure if it's going to fulfill my needs? I'm trying my best to avoid having to use MobileMe..... Help greatly appreciated, Kind regards

  • Why use hashing to create pathnames for large collections of files?

    - by Stephen
    Hi, I noticed a number of cases where an application or database stored collections of files/blobs using a has to determine the path and filename. I believe the intended outcome is a situation where the path never gets too deep, or the folders ever get too full - too many files (or folders) in a folder making for slower access. EDIT: Examples are often Digital libraries or repositories, though the simplest example I can think of (that can be installed in about 30s) is the Zotero document/citation database. Why do this? EDIT: thanks Mat for the answer - does this technique of using a hash to create a file path have a name? Is it a pattern? I'd like to read more, but have failed to find anything in the ACM Digital Library

  • Copy NSArray and replace text items with bool values

    - by Frank Martin
    I utilize a (nested) plist to populate UITableViews where users can select entries at the deepest levels and set a checkmark (or not). I want to save these selections in a same structured list where at the deepest level the NSArray contains bool values instead the text strings that are displayed in the UITableView. So how can i build from a hierarchy like the following: Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: @"Please check me" (String) a hierarchy like this? Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: 0 (NSNumber) // NSNumber for bool values I'm trying to create a deep mutable copy and replace the items at the deepest levels but have somehow the feeling that this can be done easier. Thanks for any help with this in advance. Frank

  • Must a Language that Implements Monads be Statically Typed?

    - by Morgan Cheng
    I am learning functional programming style. From this link http://channel9.msdn.com/shows/Going+Deep/Brian-Beckman-Dont-fear-the-Monads/, Brian Beckman gave a brilliant introduction about Monad. He mentioned that Monad is about composition of functions so as to address complexity. A Monad includes a unit function that transfers type T to an amplified type M(T); and a Bind function that, given function from T to M(U), transforms type M(T) to another type M(U). (U can be T, but is not necessarily). In my understanding, the language implementing monad should be type-checked statically. Otherwise, type errors cannot be found during compilation and "Complexity" is not controlled. Is my understanding correct?

  • latex page number position

    - by anton
    I am working on a long document in latex with documentclass book. I need the page number to always be in the upper right corner of each page, even if that page is the first page of a chapter (right now on 1st pages of chatpers, the page number is bottom-centered, on all other pages it's top-right). I control the position of the page number with fancyheader: \usepackage{fancyhdr} \pagestyle{fancy} \lhead{} \chead{} \rhead{\thepage} \lfoot{} \cfoot{} \rfoot{} \renewcommand{\headrulewidth}{0pt} Also, I don;t know if the problem is realted but my chapters do not start from the top of the page. There is a white area, then comes chapter X, then a newline with the chapter line. What I also want is the chapter to start from the top of the page. The main question here is how I can get the page number to always appear in the upper right corner, I mention the thing with the chapter title position only in case that might be related. Thanks.

  • SQL 2005 - Search stored procedures for text (Not all text is being searched)

    - by hamlin11
    The following bits of code do not seem to be searching the entire routine definition. Code block 1: select top 50 * from information_schema.routines where routine_definition like '%09/01/2008%' and specific_Name like '%NET' Code Block 2: SELECT ROUTINE_NAME, ROUTINE_DEFINITION FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_DEFINITION LIKE '%EffectiveDate%' AND ROUTINE_TYPE='PROCEDURE' and ROUTINE_NAME like '%NET' I know for a fact that these bits of SQL work under most circumstances. The problem is this: When I run this for "EffectiveDate" which is buried at line ~800 in a few stored procedures, these stored procedures never show up in the results. It's as if "like" only searches so deep. Any tips on fixing this? I want to search the ENTIRE stored procedure for the specified text. Thanks!

  • How can I change the filename of a shared library after building a program that depends on it?

    - by ZorbaTHut
    I have a program that depends on a shared library it expects to find deep inside a directory structure. I'd like to move that shared library out and into a better place. On OS X, this can be done with install_name_tool. I'm unable to find an equivalent for Linux. For reference, readelf -d myprogram spits out the following paraphrased output: Dynamic section at offset 0x1e9ed4 contains 30 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [this/is/terrible/library.so] 0x00000001 (NEEDED) Shared library: [libGL.so.1] 0x00000001 (NEEDED) Shared library: [libGLU.so.1] 0x00000001 (NEEDED) Shared library: [libstdc++.so.6] and I would like to errata "this/is/terrible/library.so" to be "shared/library.so". I know about RPATH and it isn't what I'm looking for, I don't need to change search paths globally.

  • Building a modular Website with Zend Framework: Am I on the right way?

    - by Oliver
    Hi, i´m a little bit confused by reading all this posts an tutorials about staring with Zend, because there a so many different ways to solve a problem. I only need a feedback about my code to know if iam on the right way: To simply get a (hard coded) Navigation for my side (depending on who is logged in) i build a Controller Plugin with a postDispatch method that holds following code: public function postDispatch(Zend_Controller_Request_Abstract $request) { $menu = new Menu(); //Render menu in menu.phtml $view = new Zend_View(); //NEW view -> add View Helper $prefix = 'My_View_Helper'; $dir = dirname(__FILE__).'/../../View/Helper/'; $view->addHelperPath($dir,$prefix); $view->setScriptPath('../application/default/views/scripts/menu'); $view->menu = $menu->getMenu(); $this->getResponse()->insert('menu', $view->render('menu.phtml')); } Is it right that i need to set the helper path once again? I did this in a Plugin Controller named ViewSetup. There i do some setup for the view like doctype, headlinks, helper paths...(This step is from the book: Zend Framework in Action) The Menu class which is initiated looks like this: class Menu { protected $_menu = array(); /** * Menu for notloggedin and logged in */ public function getMenu() { $auth = Zend_Auth::getInstance(); $view = new Zend_View(); //check if user is logged in if(!$auth->hasIdentity()) { $this->_menu = array( 'page1' => array( 'label' => 'page1', 'title' => 'page1', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page1')) ), 'page2' => array( 'label' => 'page2', 'title' => 'page2', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page2')) ), 'page3' => array( 'label' => 'page3', 'title' => 'page3', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page3')) ), 'page4' => array( 'label' => 'page4', 'title' => 'page4', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page4')) ), 'page5' => array( 'label' => 'page5', 'title' => 'page5', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page5')) ) ); } else { //user is vom type 'client' //.. } return $this->_menu; } } Here´s my view script: <ul id="mainmenu"> <?php echo $this->partialLoop('menuItem.phtml',$this->menu) ?> </ul> This is working so far. My question is: is it usual to do it this way, is there anything to improve? I´m new to Zend and in the web are many deprecated tutorials which often is not obvious. Even the book is already deprecated where the autoloader is mentioned. Many thanks in advance

  • How can I install Gentoo on Virtual Box//(Ubuntu 12.04)

    - by Curious Apprentice
    I'm googling for a while about how can I install Gentoo on Virtual Box. The hand book provides less information about installing it on virtual box rather on a real partition. I thought there will be a GUI tool to install Gentoo. [Now I think there is not :(] Whenever I'm booting into gentoo Im going into a LiveDVD environment where fdisk returning "command not found !" (Not sure this is a bug or Im using a wronng command) Now Im not a very exprienced user but do like to learn and play with Gentoo. Any help link will be appriciated.

  • How to implement an ItemsControl3D which can use templates of Visual3D?

    - by Christo
    I'm looking for something like a ContainerUIElement3D which supports the ItemsSource property and an ItemTemplate property which I can use within a Viewport3D. My aim is to be able to write something like: <ItemsControl3D ItemsSource="{Binding Path=MyItems}"> <ItemsControl3D.ItemTemplate> <DataTemplate3D> <!-- My template which defines the binding to each item. --> <DataTemplate3D> </ItemsControl3D.ItemTemplate> </ItemsControl3D> I'm looking for tips on how to implement this. The first tricky part is to create a DataTemplate3D which can construct the Visual3D needed to add to the ItemsControl3D. I've been using .NET reflector to browse through the implementation of ItemsControl and DataTemplate, but I soon realised that I don't have a deep enough understanding and enough time to come up with a solution on my own.

  • Blackberry Won't Sync: Says Processing

    - by Noah
    I have a blackberry storm 2 and I have it set up to sync, just like I've done with all the other ones in the company. They pull the address book/contacts from outlook, and aren't synced to an exchange server. I have everything setup and then when I hit synchronize it flashes "processing" the phone shows it trying to sync and then it is done in less than a second. It did warn me that the computer was not supplying enough power to charge the device and it said that I should make sure the drivers are correct. Also, I was warned that the device might not function properly down in the bottom right hand corner. Any ideas? I've uninstalled and reinstalled the blackberry software off the disc.

  • Memory management (segmentation and paging) in 80286 and 80386: How does it work?

    - by Andrew J. Brehm
    I found lots of Web sites and books explaining how memory management worked on the 8086 and later x86 CPUs in Real Mode. I understand, I think, how two 16 bit values, segment address and offset are combined to get a linear 20 bit physical address (shift segment four bits to the left, add offset; segments are 64K and start every 16 bytes). But I couldn't find any good Web sites or books that explained how memory management works in Protected Mode, specifically the differences between 80286 and 80386. Can anyone point me to a good Web site or book (or explain it right here)? (For extra credit, i.e. an upvote, how does it work in Long Mode?)
