• How do I choose what and when to cache data with ob_start rather than query the database?

  - by Tim Santeford

  I have a home page that has several independent dynamic parts. The parts consist of a list of recent news from the company, a site statistics panel, and the online status of certain employees. The recent news changes monthly, site statistics change daily, and online statuses change on a per minute bases. I would like to cache these panels so that the db is not hit on every page load. Is using ob_start() then ob_get_contents() to cache these parts to a file the correct way to do this or is there a better method in PHP5 for doing this? In asking this question I'm trying to answer these additional questions: How can I determine the correct approach for caching this data without doing extensive benchmarking? Does it make sense to cache these parts in different files and then join them together per requests or should I re-query the data and cache once per minute? I'm looking for a rule of thumb for planning pages and for situations where doing testing is not cost effective (The client is not paying enough for it I mean). Thanks!

• How does git fetches commits associated to a file ?

  - by liadan

  I'm writing a simple parser of .git/* files. I covered almost everything, like objects, refs, pack files etc. But I have a problem. Let's say I have a big 300M repository (in a pack file) and I want to find out all the commits which changed /some/deep/inside/file file. What I'm doing now is: fetching last commit finding a file in it by: fetching parent tree finding out a tree inside recursively repeat until I get into the file additionally I'm checking hashes of each subfolders on my way to file. If one of them is the same as in commit before, I assume that file was not changed (because it's parent dir didn't change) then I store the hash of a file and fetch parent commit finding file again and check if hash change occurs if yes then original commit (i.e. one before parent) was changing a file And I repeat it over and over until I reach very first commit. This solution works, but it sucks. In worse case scenario, first search can take even 3 minutes (for 300M pack). Is there any way to speed it up ? I tried to avoid putting so large objects in memory, but right now I don't see any other way. And even that, initial memory load will take forever :( Greets and thanks for any help!

• Considering moving from Java/Spring MVC to Grails

  - by MDS

  I'm currently using Java & Spring (MVC) to create a webapp, and I'm considering moving to Grails. I'd appreciate feedback/insight on the following: I have multiple application contexts in the current Java/Spring webapp that I load through the web.xml ContextLoaderListener; is it possible to have multiple application contexts in Grails? If, yes, how? This webapp extensively uses a CXF restful web service and the current Java/Spring webapp uses the bundled CXF HTTP client. Can I continue to use the (Java) CXF HTTP Client in Grails? I implemented Spring Security using a custom implementation of UserDetails and UserDetailsService, can I re-use these implementations in Grails "as is" or must I re-implement them? There is an instance where I've relied on Spring's jdbc template (rather than the available ORM) and an additional data source I defined in app context, can I re-use this in Grails? I plan on using Maven as the project management tool; are there any issues of using Maven with Grails where there is a combination of groovy and java?

• Shadowbox + jQuery not working - No errors.

  - by Shelton

  First, apologies. I'm a js newb. I'm attempting to trigger a shadowbox with the load of a specific page - a "pop-up" if you will. Nothing happens and according to firebug, there are no errors to report. I should note that this is wordpress, so I'm using the default jQuery call and also shadowbox rolled into a WP plug-in. Shadowbox does work properly in other areas of the site, as do jQuery functions. noConflict() is used because WP also loads prototype by default, which conflicts with the jQuery dollar sign. var $j = jQuery.noConflict(); $j(function(){ //Set cookie $j.cookie('padpop_viewed',true); // open a welcome message as soon as the window loads $j(function() { Shadowbox.open({ content: '<div width="600" height="460" style="margin:auto;"><a href="<?php bloginfo('url');?>"/products/"><img src="<?php bloginfo('template_url');?>/images/ipad-pop.jpg" width="600" height="460" alt="Redacted"/></a></div>', player: "html", height: "470", width: "610" }); }); }); Any help here would be greatly appreciated as I have spent hours consulting the documentation of each aspect of this. Thanks, S.

• Plugin architecture in C using libdl

  - by LukeN

  I've been toying around, writing a small IRC framework in C that I'm now going to expand with some core functionality - but beyond that, I'd like it to be extensible with plugins! Up until now, whenever I wrote something IRC related (and I wrote a lot, in about 6 different languages now... I'm on fire!) and actually went ahead to implement a plugin architecture, it was inside an interpreted language that had facilities for doing (read: abusing) so, like jamming a whole script file trough eval in Ruby (bad!). Now I want to abuse something in C! Basically there's three things I could do define a simple script language inside of my program use an existing one, embedding an interpreter use libdl to load *.so modules on runtime I'm fond of the third one and raather avoid the other two options if possible. Maybe I'm a masochist of some sort, but I think it could be both fun and useful for learning purposes. Logically thinking, the obvious "pain-chain" would be (lowest to highest) 2 - 1 - 3, for the simple reason that libdl is dealing with raw code that can (and will) explode in my face more often than not. So this question goes out to you, fellow users of stackoverflow, do you think libdl is up to this task, or even a realistic thought?

• Xml updating with linq not working when quering

  I have problem i'm trying to update a specific part of the XML with the linq query but it doesn't work. So i an xml file: <?xml version="1.0" encoding="utf-8"?> <DesignConfiguration> <Design name="CSF_Packages"> <SourceFolder>C:\CSF_Packages</SourceFolder> <DestinationFolder>C:\Documents and Settings\xxx</DestinationFolder> <CopyLookups>True</CopyLookups> <CopyImages>False</CopyImages> <ImageSourceFolder>None</ImageSourceFolder> <ImageDesinationFolder>None</ImageDesinationFolder> </Design> </DesignConfiguration> I want to select the part where the part where there is Design name="somethning" and get the descendants and then update the descendants value that means this part: <SourceFolder>C:\CSF_Packages</SourceFolder> <DestinationFolder>C:\Documents and Settings\xxx</DestinationFolder> <CopyLookups>True</CopyLookups> <CopyImages>False</CopyImages> <ImageSourceFolder>None</ImageSourceFolder> <ImageDesinationFolder>None</ImageDesinationFolder> I have this code: XDocument configXml = XDocument.Load(configXMLFileName); var updateData = configXml.Descendants("DesignConfiguration").Elements().Where(el => el.Name == "Design" && el.Attribute("name").Value.Equals("AFP_GRAFIKA")).FirstOrDefault(); configXml.Save(configXMLFileName); I'm getting the null data in the updateData varibale. When I'm trying the Descendat's function through QuickWatch it also returns a null value. When I'm checking the configXML variable it has data that is my whole xml. What am I doing wrong?

• (Python/Pyramid) Better ways to have standard list/form editors?

  - by badcat

  I'm working on a number of Pyramid (former Pylons) projects, and often I have the need to display a list of some content (let's say user accounts, log entries or simply some other data). A user should be able to paginate through the list, click on a row and get a form where he/she can edit the contents of that row. Right now I'm always re-inventing the wheel by having Mako templates which use webhelpers for the pagination, Jquery UI for providing a dialog and I craft the editor form and AJAX requests on the client and server side by hand. As you may know, this eats up painfully much time. So what I'm wondering is: Is there a better way of providing lists, editor dialog and server/client communication about this, without having to re-invent the wheel every time? I heard Django takes off a big load of that by providing user accounts and other stuff out of the box; but in my case it's not just about user accounts, it can be any kind of data that is stored on the server-side in a SQL database, which should be able to be edited by a user. Thanks in advance!

• Recommendation for a Pagination procedure AJAX PHP

  - by Jamex

  Hi, I am not sure the correct terminology for the process that I am trying to describe. I don't even know which platform is underlying the technique. If you understand my description, please give the link to the site(s) and or the keyword name of the process. I think it is done by AJAX, but I am not certain. I use php as the backend code, I just need to find a way to dynamically display the results. Please give suggestions. I forgot the name of the sites that use this, and my link history expired. TIA Description: The page would have a search form and options. After the user submits, the search is initiated, and the results appear inside the dedicated result area. The page does not refresh, just the info inside the result area. The display area will show 20 (or whatever) results (lines). There will be next, and previous buttons. If you hit next, the next set of results will display. I am writing a code that generates 20 results for each display. There is no set number of results, so the results might have a start/first page, but do not have an end page. Each time the user hits 'next', the program would generate/load new results. It would also store previous results, so that when a user hits 'prev', the previous results can instantly come up. What techniques/program are theses?

• Are programming languages and methods ineffective? (assembler and C knowledge needed)

  - by b-gen-jack-o-neill

  Hi, for a long time, I am thinking and studying output of C language compiler in asemlber form, as well as CPU architecture. I know this may be silly to you, but it seems to me that something is very ineffective. Please, don´t be angry if I am wrong, and there is some reason I do not see for all these principles. I will be very glad if you tell me why is it designed this way. I actually trully believe I am wrong, I know the genius minds of people which get PCs together knew a reason to do so. What exactly, do you ask? I´ll tell you right away, I use C as a example: 1, Stack local scope memory allocation: So, typical local memory allocation uses stack. Just copy esp to ebp and than allocate all the memory via ebp. OK, I would understand this if you explicitly need allocate RAM by default stack values, but if I do understand it correctly, modern OS use paging as a translation layer between application and physical RAM, when adress you desire is further translated before reaching actuall RAM byte. So why don´t just say 0x00000000 is int a,0x00000004 is int b and so? And access them just by mov 0x00000000,#10? Becouse you wont actually access memory blocks 0x00000000 and 0x00000004 but those your OS set the paging tables to. Actually, since memory allocation by ebp and esp use indirect adressing, "my" way would be even faster. 2, Variable allocation duplicitly: When you run aaplication, Loader load its code into RAM. When you create variable, or string, compiler generates code that pushes these values on the top o stack when created in main. So there is actuall instruction for do so, and that actuall number in memory. So, there are 2 entries of the same value in RAM. One in fomr of instruction, second in form of actuall bytes in the RAM. But why? Why not to just when declaring variable count at which memory block it would be, than when used, just insert this memory location?

• JavaScript: When does JavaScript evaluate a function, onload or when the function is called?

  - by Benj

  When does JavaScript evaluate a function? Is it on page load or when the function is called? The reason why I ask is because I have the following code: function scriptLoaded() { // one of our scripts finished loading, detect which scripts are available: var jQuery = window.jQuery; var maps = window.google && google.maps; if (maps && !requiresGmaps.called) { requiresGmaps.called = true; requiresGmaps(); } if (jQuery && !requiresJQuery.called) { requiresJQuery.called = true; requiresJQuery(); } if (maps && jQuery && !requiresBothJQueryGmaps.called) { requiresBothJQueryGmaps.called = true; requiresBothJQueryGmaps(); } } // asynch download of script function addScript(url) { var script = document.createElement('script'); script.src = url; // older IE... script.onreadystatechange=function () { if (this.readyState == 'complete') scriptLoaded.call(this); } script.onload=scriptLoaded; document.getElementsByTagName('head')[0].appendChild(script); } addScript('http://google.com/gmaps.js'); addScript('http://jquery.com/jquery.js'); // define some function dependecies function requiresJQuery() { // create JQuery objects } function requiresGmaps() { // create Google Maps object, etc } function requiresBothJQueryGmaps() { ... } What I want to do is perform asynchronous download of my JavaScript and start at the earliest possible time to begin executing those scripts but my code has dependencies on when the scripted have been obviously downloaded and loaded. When I try the code above, it appears that my browser is still attempting to evaluate code within my require* functions even before those functions have been called. Is this correct? Or am I misunderstanding what's wrong with my code?

• asp.net - updatepannel can't read innerHTML?

  - by omega

  In my asp.net page, I have a jquery sortable accordian (in an update panel) I use so that clients can re-arrange items. Then to save it, users would click a button (thats created from jquery) and it would traverse through the accoridion in the DOM, and write the info to a asp control textbox. Then invoke the click function of a asp button control, which then reads that information and saves the data. But now I decided to simplify this step, and use html agility pack in c#, so users click the asp button control (inside an update panel), and then it would get the innerHTML of the accordian. But the problem is, the html it's getting is not the reflecting the changes a user can make to the accordion (i.e. re arranging it), it the same as when the DOM was ready on page load... But note that, using javascript to write the innerHTML to a textbox, then from the c# function, I can read the up to date html from the accordian. Does anyone know why this is happening and how to get the up to data html from the accordian in c#?

• Apache's AuthDigestDomain and Rails Distributed Asset Hosts

  - by Jared

  I've got a server I'm in the process of setting up and I'm running into an Apache configuration problem that I can not get around. I've got Apache 2.2 and Passenger serving a Rails app with distributed asset hosting. This is the feature of Rails that lets you serve your static assets from assets0.example.com, assets1, assets2, and so on. The site needs to be passworded until launch. I've set up HTTP authentication on the site using Apache's mod_auth_digest. In my configuration I'm attempting to use the AuthDigestDomain directive to allow access to each of the asset URLs. The problem is, it doesn't seem to be working. I get the initial prompt for the password when I load the page, but then the first time it loads an asset from one of the asset URLs, I get prompted a 2nd, 3rd, or 4th time. In some browsers, I get prompted for every single resource on the page. I'm hoping that this is only a problem of how I'm specifying my directives and not a limitation of authorization in Apache itself. See the edited auth section below: <Location /> AuthType Digest AuthName "Restricted Site" AuthUserFile /etc/httpd/passwd/passwords AuthGroupFile /dev/null AuthDigestDomain / http://assets0.example.com/ http://assets1.example.com/ http://assets2.example.com/ http://assets3.example.com/ require valid-user order deny,allow allow from all </Location>

• Custom punctuation function making script run over the php's 60s runtime limit

  - by webmasters

  I am importing allot of product data from an XML file (about 5000 products). When I run the script I can make it work in about 10-12 seconds. Now, when I add this punctuation function which makes sure each product description ends with a punctuation sign, the code runs until the php 60 seconds loadtime on my server but I'm not getting any errors. I have error reporting turned on. I just get a final error that the script could not load in 60 seconds. The question is, looking at this function, is it that resource consuming? What can I do to make it faster? function punctuation($string){ if(strlen($string) > 5){ // Get $last_char $desired_punctuation = array(".",",","?","!"); $last_char = substr($string, -1); // Check if $last_char is in the $desired_punctuation array if(!in_array($last_char, $desired_punctuation)){ // strip the $mytrim string and get only letters at the end; while(!preg_match("/^[a-zA-Z]$/", $last_char)){ $string = substr($string, 0, -1); $last_char = substr($string, -1); } // add "." to the string $string .= '.'; } } return $string; } If the function is ok, the long runtime must come from something else which I'll have to discover. I just want your input on this part.

• C#: How to implement a smart cache

  - by Svish

  I have some places where implementing some sort of cache might be useful. For example in cases of doing resource lookups based on custom strings, finding names of properties using reflection, or to have only one PropertyChangedEventArgs per property name. A simple example of the last one: public static class Cache { private static Dictionary<string, PropertyChangedEventArgs> cache; static Cache() { cache = new Dictionary<string, PropertyChangedEventArgs>(); } public static PropertyChangedEventArgs GetPropertyChangedEventArgsa(string propertyName) { if (cache.ContainsKey(propertyName)) return cache[propertyName]; return cache[propertyName] = new PropertyChangedEventArgs(propertyName); } } But, will this work well? For example if we had a whole load of different propertyNames, that would mean we would end up with a huge cache sitting there never being garbage collected or anything. I'm imagining if what is cached are larger values and if the application is a long-running one, this might end up as kind of a problem... or what do you think? How should a good cache be implemented? Is this one good enough for most purposes? Any examples of some nice cache implementations that are not too hard to understand or way too complex to implement?

• How to convert a string to variable name

  - by p1xelarchitect

  I'm loading several external JSON files and want to check if they have been successfully cached before the the next screen is displayed. My strategy is to check the name of the array to see if it an object. My code works perfectly when I check only a single array and hard code the array name into my function. My question is: how can i make this dynamic? not dynamic: (this works) $("document").ready(){ checkJSON("nav_items"); } function checkJSON(){ if(typeof nav_items == "object"){ // success... } } dynamic: (this doesn't work) $("document").ready(){ checkJSON("nav_items"); checkJSON("foo_items"); checkJSON("bar_items"); } function checkJSON(item){ if(typeof item == "object"){ // success... } } here is the a larger context of my code: var loadAttempts = 0; var reloadTimer = false; $("document").ready(){ checkJSON("nav_items"); } function checkJSON(item){ loadAttempts++; //if nav_items exists if(typeof nav_items == "object"){ //if a timer is running, kill it if(reloadTimer != false){ clearInterval(reloadTimer); reloadTimer = false; } console.log("found!!"); console.log(nav_items[1]); loadAttempts = 0; //reset // load next screen.... } //if nav_items does not yet exist, try 5 times, then give up! else { //set a timer if(reloadTimer == false){ reloadTimer = setInterval(function(){checkJSON(nav_items)},300); console.log(item + " not found.

• Recommendation for using equals in Entities and avoiding LazyInitializationExceptions?

  - by huxendupsel

  In the beginning there is a problem that wants to be solved. In my case i got an LazyInitializationException while using indexof in a Collection to retrieve an Object for manipulation. Here i start to think about using equals in EntityBeans (OR-Mapper at all). I know there are some discussions about overriding equals in association with OR-Mapper as hibernate like [1] Entities equals(), hashCode() and toString(). How to correctly implement them? [2] To equals and hashcode or not on entity classes, that is the question. [3] Overriding equals and hashCode in Java I currently have some entities which implements the equals but inside the code i could not use equals several times because of the LazyInitializationExceptions. So i had to workaround and use eg. the name property of the object to identify it's equality. From my point of view the whole 'LazyInitializationException-thing' is not really mentioned in this questions. I'd like to know have you got some good patterns or real live recommendations how to avoid such exception in an equal-Method. Shall i use some helper Methodes to distinguish if a Object of a class is already initialized (4) or should i apdicate the use of equals and use helper classes instead (2)? And what is about catching LazyInitializationExceptions in the equals? [Edit]: If you put equals in context with the initialization of the Object then it will gain importance. Sometimes it is nessesary to have the Object fully initialized but sometimes you don't want to. Because you just need the Object itself (name, id, ...) not its Collection-Properties. So just for equalization you have to reattach the Object and load the whole bunch you don't realy need? Are there any other solutions for such a problem?

• Navigation Controller with Tab Bar only on first view

  - by dinoc

  I am seeking advice on how to start my project. I need to use a combination of the navigation controller and tabbar controller but on the second screen, I need the tabbar controller not to be there. Here is a brief description of the two main screens Screen 1 will have a tabbar controller with two tabs. The first tab is a tableview and when you tap on a table cell, it drills down to Screen 2. The second tab is just a filter view that updates the table in the first tab of Screen 1. Screen two is just a details screen from the cells of Screen 1. The catch is that I don't want the TabBar on Screen 2. I am struggling with how to get started. Do I start with a Navigation-based application since I need to be able to drill down? How do I just add a tab bar to the main screen of the navigation based app? I can't start with a Tab Bar application because if I load a navigation controller inside one of the views of the tab controller, then when I drill down inside the nav controller, the tab bar still stays on the next screen when I need it to go away. Any help would be appreciated.

• Magento - save quote_address on cart addAction using observer

  - by Byron

  I am writing a custom Magento module that gives rate quotes (based on an external API) on the product page. After I get the response on the product page, it adds some of the info from the response into the product view's form. The goal is to save the address (as well as some other things, but those can be in the session for now). The address needs to be saved to the quote, so that the checkout (onestepcheckout, free version) will automatically fill those values in (city, state, zip, country, shipping method [of which there are 3]) and load the rate quote via ajax (which it's already doing). I have gone about this by using an Observer, and watching for the cart events. I fill in the address and save it. When I end up on the cart page or checkout page ~4/5 times the data is lost, and the sql table shows that the quote_address is getting save with no address info, even though there is an explicit save. The observer method's I've used are: checkout_cart_update_item_complete checkout_cart_product_add_after The code saving is: (I've tried this with the address, quote and cart all not calling save() with the same results, as well as not calling setQuote() $quote->getShippingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->getBillingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->save(); $cart->save(); I imagine there's a good chance this is not the best place to save this info, but I am not quite sure. I was wondering if there is a good place to do this without overriding a whole controller to save the address on the add to cart action. Thanks so much, let me know if I need to clarify
