• HTML 5 <video> tag vs Flash video. What are the pros and cons?

  - by Vilx-

  Seems like the new <video> tag is all the hype these days, especially since Firefox now supports it. News of this are popping up in blogs all over the place, and everyone seems to be excited. But what about? As much as I searched I could not find anything that would make it better than the good old Flash video. In fact, I see only problems with it: It will still be some time before all the browsers start supporting it, and much more time before most people upgrade; Flash is available already and everyone has it; You can couple Flash with whatever fancy UI you want for controlling the playback. I gather that the tag will be controllable as well (via JavaScript probably), but will it be able to go fullscreen? The only two pros for a <video> tag that I can see are: It is more "semantic" - which probably holds no importance to a whole lot of people, including me; It is not dependent on a single commercial 3rd party entity (Adobe) - which I also don't see as a compelling reason to switch, because free players and video converters are already available, and Adobe is not hindering the whole process in any way (it's not in their interests even). So... what's the big deal? Added: OK, so there is one more Pro... maybe. Support for mobile devices. Hard to say though. A number of thoughts race through my head about the subject: How many mobile devices are actually able to decode video at a decent speed anyway, Flash or otherwise? How long until mainstream mobile devices get the <video> support? Even if it is available through updates, how many people actually do that? How many people watch videos on web pages on their mobile phones at all? As for the semantics part - I understand that search engines might be able to detect videos better now, but... what will they do with them anyway? OK, so they know that there is a video in the page. And? They can't index a video! I'd like some more arguments here. Added: Just thought of another Cons. This opens up a whole new area of cross-browser incompatibility. HTML and CSS is quite messy already in this aspect. Flash at least is the same everywhere. But it's enough for at least one major browser vendor to decide against the <video> tag (can anyone say "Internet Explorer"?) and we have a nice new area of hell to explore. Added: A Pro just came in. More competition = more innovation. That's true. Giving Adobe more competition will probably force them to improve Flash in areas it has been lacking so far. Linux seems to be a weak spot for it, cited by many.

• problem calculating the position using php

  - by LiveEn

  I have a function below which gets name from a site. Below is the partial code, not complete. The values are passed thru a for loop using php. function funct($$name,$page) { $url="http://testserver.com/client?list=$name&page=$page"; $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,url); $result=curl_exec($ch); $dom = new DOMDocument(); @$dom->loadHTML($result); $xpath=new DOMXPath($dom); $elements = $xpath->evaluate("//div"); foreach ($elements as $element) { $name = $element->getElementsByTagName("name")->item(0)->nodeValue; $position=$position +1; echo $name.$position; } } The code works fine but when i get a name i need to add a position and for each name it will be incremented by 1 to make it contentious. But when the values for the pages are passed, for an example when i move from page 1 to page 2. the count starts again from first, next page... same problem. How can i make it continues on every page?

• How best to organize projects folders for unit tests in .NET?

  - by Dan Bailiff

  So I'm trying to introduce unit testing to my group. I've successfully upgraded a VS'05 web site project to a VS'08 web application, and now have a solution with the web app project and a unit test project. The issue now is how to fit this back into the source repository such that we don't break the build system and the unit test projects are persisted as well. Right now we have something like this: c:\root c:\root\projectA c:\root\projectB c:\root\projectC where projectA contains the sln file and all other related files/folders for the project. Now I have this new solution that looks like this: c:\root\projectA (parent folder) c:\root\projectA\projectA (the production code project) c:\root\projectA\projectA_Test (the unit test project) c:\root\projectA\TestResults c:\root\projecta\projectA.sln How do I integrate this new structure back into the code repository? I'd really prefer to keep the production code folder where it was in the source repository for the sake of the build, but is this necessary? If I keep the production code project in its usual place then where do I keep my unit test projects and how do I connect them with a sln file? Is it better to use this new structure and adjust the build process? I'd love to hear how other people are dealing with this issue of upgrading legacy projects to unit testing.

• Set bounds for markers generated by jQuery table loop?

  - by abemonkey

  I have some jQuery code that goes through a table of location results and puts corresponding pins on a map. I am having trouble figuring out how to set the bounds so that when it goes through the loop and generates the markers on the map that it zooms and pans to fit the markers in the view. I've tried implementing code from some similar questions on this site but nothing seems to be working. Please let me know what code I should be using and where the heck I should put it in my script: $(function() { var latlng = new google.maps.LatLng(44, 44); var settings = { zoom: 15, center: latlng, disableDefaultUI: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $('tr').each(function(i) { var the_marker = new google.maps.Marker({ title: $(this).find('.views-field-title').text(), map: map, clickable: true, position: new google.maps.LatLng( parseFloat($(this).find('.views-field-latitude').text()), parseFloat($(this).find('.views-field-longitude').text()) ) }); var infowindow = new google.maps.InfoWindow({ content: $(this).find('.views-field-title').text() + $(this).find('.adr').text() }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map, the_marker); }); }); }); `

• I never really understood: what is Application Binary Interface (ABI)?

  - by claws

  I never clearly understood what is an ABI. I'm sorry for such a lengthy question. I just want to clearly understand things. Please don't point me to wiki article, If could understand it, I wouldn't be here posting such a lengthy post. This is my mindset about different interfaces: TV remote is an interface between user and TV. It is an existing entity but useless (doesn't provide any functionality) by itself. All the functionality for each of those buttons on the remote is implemented in the Television set. Interface: It is a "existing entity" layer between the functionality and consumer of that functionality. An, interface by itself is doesn't do anything. It just invokes the functionality lying behind. Now depending on who the user is there are different type of interfaces. Command Line Interface(CLI) commands are the existing entities, consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: commands consumer: user Graphical User Interface(GUI) window,buttons etc.. are the existing entities, again consumer is the user and functionality lies behind. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: window,buttons etc.. consumer: user Application Programming Interface(API) functions or to be more correct, interfaces (in interfaced based programming) are the existing entities, consumer here is another program not a user. and again functionality lies behind this layer. functionality: my software functionality which solves some purpose to which we are describing this interface. existing entities: functions, Interfaces(array of functions). consumer: another program/application. Application Binary Interface (ABI) Here is my problem starts. functionality: ??? existing entities: ??? consumer: ??? I've wrote few softwares in different languages and provided different kind of interfaces (CLI, GUI, API) but I'm not sure, if I ever, provided any ABI. http://en.wikipedia.org/wiki/Application_binary_interface says: ABIs cover details such as data type, size, and alignment; the calling convention, which controls how functions' arguments are passed and return values retrieved; the system call numbers and how an application should make system calls to the operating system; Other ABIs standardize details such as the C++ name mangling,[2] . exception propagation,[3] and calling convention between compilers on the same platform, but do not require cross-platform compatibility. Who needs these details? Please don't say, OS. I know assembly programming. I know how linking & loading works. I know what exactly happens inside. Where did C++ name mangling come in between? I thought we are talking at the binary level. Where did languages come in between? anyway, I've downloaded the [PDF] System V Application Binary Interface Edition 4.1 (1997-03-18) to see what exactly it contains. Well, most of it didn't make any sense. Why does it contain 2 chapters (4th & 5th) which describe the ELF file format.Infact, these are the only 2 significant chapters that specification. Rest of all the chapters "Processor Specific". Anyway, I thought that it is completely different topic. Please don't say that ELF file format specs are the ABI. It doesn't qualify to be Interface according to the definition. I know, since we are talking at such low level it must be very specific. But I'm not sure how is it "Instruction Set Architecture(ISA)" specific? Where can I find MS Window's ABI? So, these are the major queries that are bugging me.

• Authentication and Security in my website - need advice please.

  - by Ichirichi

  Hi, I am using database with a list of username/passwords, and a simple web form that allows for users to enter their username/password. When they submit the page, I simply do a stored procedure check to authenticate. If they are authorised, then their user details (e.g. username, dob, address, company address, other important info) are stored in a custom User object and then in a session. This custom User object that I created is used throughout the web application, and also in a sub-site (session sharing). My question/problems are: Is my method of authentication the correct way to do things? I find users complaining that their session have expired although they "were not idle", possibly due the app pool recycling? They type large amounts of text and find that their session had expired and thus lose all the text typed in. I am uncertain whether the session does really reset sporadically but will Forms Authentication using cookies/cookiless resolve the issue? Alternatively should I build and store the User Object in a session, cookie or something else instead in order to be more "correct" and avoid cases like in point #2. If I go down the Forms Authentication route, I believe I cannot store my custom User object in a Forms Authentication cookie so does it mean I would store the UserID and then recreate the user object on every page? Would this not be a huge increase on the server load? Advice and answers much appreciated. L

• Which of these methods provides for the fastest page loading?

  - by chromedude

  I am building a database in MySQL that will be accessed by PHP scripts. I have a table that is the activity stream. This includes everything that goes on on the website (following of many different things, liking, upvoting etc.). From this activity stream I am going to run an algorithm for each user depending on their activity and display relevant activity. Should I create another table that stores the activity for each user once the algorithm has been run on the activity or should I run the algorithm on the activity table every time the user accesses the site? UPDATE:(this is what is above except rephrased hopefully in an easier to understand way) I have a database table called activity. This table creates a new row every time an action is performed by a user on the website. Every time a user logs in I am going to run an algorithm on the new rows (since the users last login) in the table (activity) that apply to them. For example if the user is following a user who upvoted a post in the activity stream that post will be displayed when the user logs in. I want the ability for the user to be able to access previous content applying to them. Would it be easiest to create another table that saved the rows that have already been run over with the algorithm except attached to individual users names? (a row can apply to multiple different users)

• SQL Server query

  - by carrot_programmer_3

  Hi, I have a SQL Server DB containing a registrations table that I need to plot on a graph over time. The issue is that I need to break this down by where the user registered from (e.g. website, wap site, or a mobile application). the resulting output data should look like this... [date] [num_reg_website] [num_reg_wap_site] [num_reg_mobileapp] 1 FEB 2010,24,35,64 2 FEB 2010,23,85,48 3 FEB 2010,29,37,79 etc... The source table is as follows... UUID(int), signupdate(datetime), requestsource(varchar(50)) some smple data in this table looks like this... 1001,2010-02-2:00:12:12,'website' 1002,2010-02-2:00:10:17,'app' 1003,2010-02-3:00:14:19,'website' 1004,2010-02-4:00:16:18,'wap' 1005,2010-02-4:00:18:16,'website' Running the following query returns one data column 'total registrations' for the website registrations but I'm not sure how to do this for multiple columns unfortunatly.... select CAST(FLOOR(CAST([signupdate]AS FLOAT ))AS DATETIME) as [signupdate], count(UUID) as 'total registrations' FROM [UserRegistrationRequests] WHERE requestsource = 'website' group by CAST(FLOOR(CAST([signupdate]AS FLOAT ))AS DATETIME)

• Object model design choice

  - by spinon

  I am currently working on a ASP.NET MVC reporting application using C#. This is a redesign from a PHP application that was just initially thrown together and is now starting to gain some more traction. SowWe are in the process of reworking the backend to have a more OO approach. One of the descisions I am currently wrestling with is how to structure the domain objects. Since 95% of the site is readonly I am not sure if the typical approaches are practical. Should I create domain objects for the primary pieces of the application (ticket, assignment, assignee) and then create static methods off of these areas to pull the reporting data? Or should I just skip that part and create the chart data classes and have some get method off of these classes? It's not a real big application and currenlty I am the only one developing on it. But I feel torn as to which approach. I feel that the first one is the better choice but maybe overkill given that the majority of uses is for aggregate reporting. Anybody have some good insight on why I should go one way or another?

• Which web solution should I use for my project?

  - by BenIOs

  I'm going to create a fairly large (from my point of view anyway) web project with a friend. We will create a site with roads and other road related info. Our calculations is that we will have around 100k items in our database. Each item will contain some information like location, name etc. (about 30 thing each). We are counting on having a few hundred thousand unique visitors per month. The 100k items and their locations (that will be searchable) will be the main part of the page but we will also have some articles, comments, news and later on some more social functions (accounts, forums, picture uploads etc.). We were going to use Google AppEngine to develop our project since it is really scalable and free (at least for a while). But I'm actually starting to doubt that AppEngine is right for us. It seems to be for webbapps and not sites like ours. Which system (language/framework etc.) would you guys recommend us to use? It doesn't really mater if we know the language since before (we like learning new stuff) but it would be good if it's something that is future proof.

• IE7 (sometimes) not showing website properly

  - by Ra y Mon

  We are a bit desperate... We have launched our website http://www.buscounviaje.com We tested all browsers (IE6-8, Firefox, Safari, Chrome, ...) to make sure everything was OK. However, there are some users (IE7 and IE6) that are complaining that they see everything 'white' with black letters (i.e. CSS styles not being applied). One user said he was getting an "Error 0: Object expected" However, we do not see that error in Firebug, nor on our local installations of IE6&7. Other users with IE6&7 are also visualizing the web correctly. We have no idea where the problem could be, and we cannot test it because our IE6&7 work fine. Anyone sees the web page without styles and give us a hint on where the problem might be? Reasons we can think of... we are compressing js and css and some versions of IE6&7 are not able to decompress them we are trying to use a non-existing object in javascript and some versions of IE6&7 do not like it the cache does not seem to be the problem... we guided a user through emptying his cache and he could still not see the web site correctly.

• Android Plugin for Eclipse problem

  - by tbneff

  I am using a laptop with Windows 7 Home Prem x64. I have installed Java JDK1.6.0_18 and Eclipse Gallileo. I have downloaded and installed the latest version of Android SDK with several Platforms loaded and a AVD defined. I can install the Android Eclipse plugin from the remote site stated in the instructions. The plugin installation performs without any errors and I can verify that the plugins are indeed installed. My problem begins when I go to Windows - Preferences, there is no Android section to configure. And when I go to File - New - Project, there is no Android Project to choose. I have uninstalled the plugin and reinstalled at least 10 times, trying different things and still no luck. I originally had the 64 bit version of the JDK installed, but removed it and installed the 32 bit version. Has anyone heard of this type of problem? Is it because I am using Windows 7? Thanks for any help. tbneff

• Using a CNAME with Shared Windows Azure Website

  - by user1679021

  I've been following instructions on the Azure site to add a CNAME to point to my Azure website. I have had some problems getting it to work and there seems to be some contradictory information in some of the posts. I have my website running in "Shared" mode, which according to the Azure instructions supports custom domains and indeed it seems to allow me to manage domains. But some posts seem to indicate that I have to run in reserved mode. Can anyone confirm this? Also, some posts seem to indicate that I need to add the CNAME in the Azure management portal, but I cannot find where this is. Any help appreciated? I don't really understand A records and CNAME that well. My DNS provider allows me to add both. Do I need to change both? Currently my A record points the "root" to the IP address that Azure gives me and the CNAME points www.mydomain to the Azure website host mysite.azurewebsites.net. I have left them for a while to propogate and nothing seem to happen.

• Sending variable data from one of two text boxes to javascript

  - by Enyalius

  Greetings, all! I am fairly new to JS (my background is in C++, enterprise languages like assembly and COBOL, and some light .NET), so I was wondering if I could get some advice regarding how to send variable information from one of two text boxes to some javascript and then have the JS do some basic checks and such. Here's the pseudocode for what I am trying to do: <form = webForm> <p> _____________ textboxPeople| searchIcon //a text box to search an online phonebook at my company. ------------- //It has a little "magnifying glass" icon to search //(onClick), but I would also like them to be able to //search by hitting the "enter" key on their keyboards. </p> <p> _____________ texboxIntranet| searchIcon //Same as above search textbox, but this one is used if ------------- //the user wishes to search my corporate intranet site. </form> So ends the front-facing basic form that I would like to use. Now, onClick or onEnter, I would like the form to pass the contents of the text box used as well as an identifier such as "People" or "Intranet," depending on which box is used, to some basic JS on the back end: begin JavaScript: if(identifier = 'People') fire peopleSearch(); else if(identifier = 'Intranet') fire intranetSearch(); function peopleSearch() { http://phonebook.corporate.com/query=submittedValue //This will take the person //that the user submitted in the form and //place it at the end of a URL, after which //it will open said complete URL in the //same window. } function intranetSearch() { http://intranet.corporate.com/query=submittedValue //This will function in the //same way as the people search function. } end JavaScript Any thoughts/suggestions would be greatly appreciated. Thank you all in advance!

• Writing own Unix shell in C - Problems with PATH and execv

  - by user1287523

  I'm writing my own shell in C. It needs to be able to display the users current directory, execute commands based on the full path (must use execv), and allow the user to change the directory with cd. This IS homework. The teacher only gave us a basic primer on C and a very brief skeleton on how the program should work. Since I'm not one to give up easily I've been researching how to do this for three days, but now I'm stumped. This is what I have so far: Displays the user's username, computername, and current directory (defaults to home directory). Prompts the user for input, and gets the input Splits the user's input by " " into an array of arguments Splits the environment variable PATH by ":" into an array of tokens I'm not sure how to proceed from here. I know I've got to use the execv command but in my research on google I haven't really found an example I understand. For instance, if the command is bin/ls, how does execv know the display all files/folders from the home directory? How do I tell the system I changed the directory? I've been using this site a lot which has been helpful: http://linuxgazette.net/111/ramankutty.html but again, I'm stumped. Thanks for your help. Let me know if I should post some of my existing code, I'm wasn't sure if it was necessary though.

• Should I learn two (or more) programming languages in parallel?

  - by c_maker

  I found entries on this site about learning a new programming language, however, I have not come across anything that talks about the advantages and disadvantages of learning two languages at the same time. Let's say my goal is to learn two new languages in a year. I understand that the definition of learning a new language is different for everyone and you can probably never know everything about a language. I believe in most cases the following things are enough to include the language in your resume and say that you are proficient in it (list is not in any particular order): Know its syntax so you can write a simple program in it Compare its underlying concepts with concepts of other languages Know best practices Know what libraries are available Know in what situations to use it Understand the flow of a more complex program At least know most of what you do not know I would probably look for a good book and pick an open source project for both of these languages to start with. My questions: Is it best to spend 5 months learning language#1 then 5 months learning language#2, or should you mix the two. Mixing them I mean you work on them in parallel. Should you pick two languages that are similar or different? Are there any advantages/disadvantages of let's say learning Lisp in tandem with Ruby? Is it a good idea to pick two languages with similar syntax or would it be too confusing? Please tell me what your experiences are regarding this. Does it make a difference if you are a beginner or a senior programmer?

• ASP.NET - Google Chrome caching DropDownList selections

  - by Fake

  I'm experiencing what seems to be a caching issue with Google Chrome and Safari on my cart page. In the cart there are 2 dropdown lists. When you hit the checkout button after changing the values in the dropdown lists, it commits what's selected in the lists to the database. It's a little bit hard to explain the unexpected behavior so I will try to write it out step by step with an illustration of my problem. Lets say the first dropdown list has the values of: VALUE1 VALUE2 VALUE3 And the second dropdown list has the values of: DUMBO1 DUMBO2 DUMBO3 I add an item to my cart. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I hit Checkout. Database says: VALUE1, DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) I hit the back button. Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 I drop down the VALUE1 combo and select VALUE2, VALUE2 is selected momentarily and then the site posts back and VALUE1 is re-selected in the drop down list (from being reloaded from the DB) MOMENTARILY Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 THEN AFTER POSTBACK FROM DROPDOWNLIST_SELECTIONCHANGED EVENT Screen Says: VALUE1, DUMBO1 Database Says: VALUE1, DUMBO1 Hit Checkout. Database Says VALUE1 ,DUMBO1 (I can't see the dropdown lists after I hit checkout because i'm not at the cart page) Go back. Screen Says: VALUE2, DUMBO1 Database Says: VALUE1, DUMBO1 So it appears that it's remembering my selection of VALUE2 even though it jumped back to VALUE1 before I checked out. It seems to be a caching problem, however I've got some no-cache code to prevent caching of that page that works great in firefox and internet explorer but seems to be failing in Chrome and Safari. I'm basically returning in the headers for the cart page: no-cache, no-store, and must-revalidate to attempt to prevent caching, but based on this scenario it seems to be caching the page anyway and not reloading it when I hit the back button. I am open to any solutions or suggestions at this point. Thanks!

• Changing style sheets depending on useragent

  <script language="Javascript"> var deviceIphone = "iPhone"; var deviceIpod = "iPod"; //Initialize our user agent string to lower case. var uagent = navigator.userAgent.toLowerCase(); //************************** // Detects if the current device is an iPhone. function DetectiPhone() { if (uagent.search(deviceIphone) > -1) {document.write('<link rel="stylesheet" type="text/css" href="ui/mobile/css/site.css">'); } etc... Above is the start of my code. I am trying to change the CSS file depending on what platform the user is using. I currently use media="screen ... " but it doesn't work with the amount of platforms I'm trying to use. I need something a lot more detailed/complex that is why I'm turning to useragents. Any ideas why the css file doesn't change on my iPhone using the above code? Better yet, any ideas on another way to change style sheets depending on the users platform/screen resolution?

• Upload .txt and keep formating

  - by s2xi

  I have been trying to upload a .txt to my server via a simple php script I made. Everything seems to uploaded correctly, if I open the .txt in Dreamweaver I can see all the formatting is still in tact with spaces and paragraph breaks. The problem I have is when I try to open that file with PHP and import the contents onto my site. I'm not using an editor right now, just a simple div where the contents are echoed. I don't have much experience with uploading/downloading using PHP. Am I not using a command to handle the file contents and keep the initial formatting? In the end I want the user to upload a file, and have PHP read the file and extract certain elements from it based on the number of spaces between paragraph breaks and such. I was able to actually echo the .txt using URLENCODE() which kept the formatting and made all my spaces +'s. Thats the closes I got, but the original file isn't uploaded in the format so I can't do a count for +'s and select x characters after the last +. Hmmm, if someone knows of a script already available that can do this or similar to with me just tweaking that would be awesome.

• Error logging/handling on application basis?

  - by Industrial

  Hi everybody, We have a web server that we're about to launch a number of applications on. On the server-level we have managed to work out the error handling with the help of Hyperic to notify the person who is in charge in the event of a database/memcached server is going down. However, we are still in the need of handling those eventual error and log events that happen on application level to improve the applications for our customers, before the customers notices. So, what's then a good solution to do this? Utilizing PHP:s own error log would quickly become cloggered if we would run a big number of applications at the same time. It's probably isn't the best option if you like structure. One idea is to build a off-site lightweight error-handling application that has a REST/JSON API that receives encrypted and serialized arrays of error messages and stores them into a database. Maybe it could, depending on the severity of the error also be directly inputted into our bug tracker. Could be a few well spent hours, but it seems like a quite fragile solution and I am sure that there's better more-reliable alternatives out there already. Thanks,

• How can I use "PHP Simple HTML DOM Parser" to get the contents of an <h1></h1> tag?

  - by KeriLynn

  I'm new to PHP =) Right now I am using PHP includes for my site template. I have my header, containing all my <head></head> info. What I want to do is write a code that will take the contents of the <h1></h1> tag from the page, and echo it into the <title></title> tag in my header.php include. I got the PHP Simple HTML DOM Parser from here: http://simplehtmldom.sourceforge.net/, and I found a code (I forget where in all my googling) that goes like this: <?php $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $html = file_get_html('http://www.google.com/'); foreach($html->find('#content h1') as $element){ echo $element->plaintext;} ?> That I think is supposed to echo the h1 tag contents? Like I said, I'm new to PHP and I only know the basics, and I don't know really know any OOP (yet), so I'm sorry if I'm asking a dumb question. It looks like it's getting the current page, then putting the contents of the h1 tag into the variable $element, and then echoing it. But nothing happens when I put it into my page. Can anyone help me with what I'm doing wrong? Thank you for reading!! =)
