  • General Questions on setting up Subversion (w/Netbeans) and web development workflow.

    - by Roeland
    Hey guys, I am web developer who currently works mostly on his own but, some projects require outside coding help (my brother.) Anyway, after running in to the problem of "working on the same files" and "saving over each others edits" I decided to research ways to avoid this. Through the help of stackoverflow I decided on subversion. My setup is the following: A windows 2008 server with a clean install. My desktop which is on the local network of the server. Then my brothers desktop which is at his house, not on lan. We both prefer to use netbeans for development. My Questions: How do we set this thing up correctly and most optimally. Here is my current setup and work flow. dev site: in the past I just created sub domains with my web host for test sites (company1.bythepixel.com, company2.bythepixel.com), and editted those sites with netbeans set up having remote sources (ftp). how do i set up my netbeans now? should I set it up with remote sources? I guess I may need to set up a web server on my local server. I'm just not sure of the work flow. When i hit save in netbeans.. will it update the repository.. then do i need to update the site from the repository somehow? live site: when going live, i would just copy all the files from the dev site into the live site. from what i gather i should be able to update the site from the dev repository? Currently I am toying with virtualsvn server (http://www.visualsvn.com/server/) on my local server. It looks like it is set up to use the http protocol. Is there advantages to this or should I consider something that does the file//. Do you recommend any other subversion software that would run on my 2008 box? how will my brother connect? should i set up a permanent vpn from his house to mine? suggestions? (not that important) how do I deal with databases, there anyway to do subversion on database? I know I have a lot of questions and I am trying to read / make sense of the free online subversion book, but its all so overwhelming! Wish there was a small subversion for dummies guide :)

  • Odd UI bug in Xcode 4.3.2

    - by scordova88
    I have this annoying UI bug when using xCode 4.3.2. Every time i press the space bar, the whole text scroll view jumps. Does anyone know why this happens, or how to stop it? edit: is happens, for example, when I'm writing comments in the code and the sentence contains a space. IT can be anywhere on the document, even in the center, doesnt have to be at the bottom of the page. After it "jumps" it goes back to where it was.

  • Windows program to remove titlebar, frame, etc from a window?

    - by Nelson
    I like playing computer games in windowed mode, as opposed to full screen. I don't like staring at the title bar, frame, and other UI junk. I also don't like seeing other stuff on my desktop around the window. Is there a simple Windows program that will strip the UI chrome off of an arbitrary window from some other application? Extra points for an easy way to put a black screen underneath the window, hiding the desktop. Note: I'm looking specifically to handle windows that are smaller than my desktop size. There's a variety of 'windowed maximized' options that make a window exactly the desktop size, and positioned so all the UI decorations are off screen. (E.g.: ShiftWindow). I'm trying to strip all the decorations away from a window that's smaller than desktop size.

  • Windows 8 Modern UI searching in files doesn't work

    - by Peter Jansen
    I have a problem with my search in Windows 8. When I search through the Modern UI style (WinF) for files, it won't return a single result from none of my drives. Searching via Windows Explorer works fine. I had the same problem in Windows 8 Consumer Preview, but it worked in Developer Preview. And I looked on the net for other users with similar problems, but I haven't found anything. Is there someone who knows what the problem might be?

  • jQuery Autocomplete & jTemplates - handling response

    - by Diegos Grace
    Has anyone had any experience with using jTemplates to display autocomplete results. I have the following $("#address-search").autocomplete({ source: "/Address/SearchAddress", minLength: 2, delay: 400, focus: function (event, ui) { $('#address-search').val(ui.item.name); return false; }, parse: function(data) { $("#autocomplete-results").setTemplate($("#templateHolder").html()); $("#autocomplete-results").processTemplate(data); }, select: function (event, ui) { $('#address-search').val(ui.item.name); $('#search-address-id').val(ui.item.id); $('#search-description').html(ui.item.address); }); and the simple jtemplate holder: <script type="text/html" id="templateHolder"> <ul class="autocomplete"> {#foreach $T as data} <li>{$T.name}</li> {#/for} </ul> </script> Above i'm using 'Parse' to format results, I've also tried the autocomplete result method but not having any luck so far. The only success I've had is by using the private method ._renderItem and formatting the data that way but we want to render the output using the jTemplate. Any advice appreciated.

  • What's the best practice to add default function to jQuery Dialog open/close events?

    - by BlueFox
    Hi All, I'm trying to define some default behaviours for my jQuery Dialogs like the following: (function($) { /** * Overriding default options **/ $.ui.dialog.defaults.bgiframe = true; $.ui.dialog.defaults.open = function() { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','hidden'); $('html').css('overflow-x','hidden'); } else { // disable scrollbar for other browsers $('body').css('overflow','hidden'); } }; $.ui.dialog.defaults.beforeclose = function(event, ui) { if ($('.ui-widget-overlay').length == 0) return; if ($.browser.msie) { // scrollbar fix for IE $('html').css('overflow-y','auto'); $('html').css('overflow-x','auto'); } else { // disable scrollbar for other browsers $('body').css('overflow','auto'); } }; })(jQuery); The above works when I have no custom open/beforeclose function specified when the dialog is created. So I'm wondering what is the best practice to add these functionality into all my dialogs, while preserving the ability to specify open/beforeclose functions.

  • grailsui plugin for accordion not working

    - by inquirer
    Hi! I have been trying to figure out what's wrong with grailsui accordion. I have checked out the sample source files (http://guidemo.googlecode.com/svn/trunk/) from different ui tags, like menu, datatable and etc. they are working fine but the accordion is not working properly. All i can see is all of the divs shown. the panels are not moving since they are already shown. I've also followed the screencast for it. I've used the yui-skin-sam class name and I've downloaded the grails plugins.grails-ui=1.2-SNAPSHOT. I am not sure what's wrong.I used the rich-ui plugin and it is working great. But there are still features that are not in rich-ui compared to the possible configurations for the grails-ui tags. Anyway. if you have any suggestions to what js library I may use for a grails application or if you have a working grails-ui accordion sample, I would really appreciate it. Thanks in advance. Hope you can help me since I am still new to Grails.

  • book about psychology of decision and psychology of human

    - by boos
    I'm a unix developer and i want to make career in project/people management as first step. I think sometimes is better to have good communication skill and in general more human skill to make career more fast. Almost in Italy, a lot of people made career development more fast for his human skill and not for his technical skill. Anyone have read some book about psychology to better manage how people and personality work and to exploit decision making situation in the right way? I have found some interesting book about people personality and psychology of decision, but i am in doubt about the usefulness about reading such book. anyone have some experience in this path ? Anyone have found useful to read similar book about how people work, to manage career development in a more fast way and handle people and decision in a more useful way? i have already read peopleware. The table of content of one of this book have: 1 - Judicment and decision 2 - Euristics and sistematics error 3 - Estimating probability and frequency prediction 4 - Risk and decision 5 - rappresentation and decision 6 - Memory, attention and decision. Etc. what do you think about ?

  • More Animation - Self Dismissing Dialogs

    - by Duncan Mills
    In my earlier articles on animation, I discussed various slide, grow and  flip transitions for items and containers.  In this article I want to discuss a fade animation and specifically the use of fades and auto-dismissal for informational dialogs.  If you use a Mac, you may be familiar with Growl as a notification system, and the nice way that messages that are informational just fade out after a few seconds. So in this blog entry I wanted to discuss how we could make an ADF popup behave in the same way. This can be an effective way of communicating information to the user without "getting in the way" with modal alerts. This of course, has been done before, but everything I've seen previously requires something like JQuery to be in the mix when we don't really need it to be.  The solution I've put together is nice and generic and will work with either <af:panelWindow> or <af:dialog> as a the child of the popup. In terms of usage it's pretty simple to use we  just need to ensure that the popup itself has clientComponent is set to true and includes the animation JavaScript (animateFadingPopup) on a popupOpened event: <af:popup id="pop1" clientComponent="true">   <af:panelWindow title="A Fading Message...">    ...  </af:panelWindow>   <af:clientListener method="animateFadingPopup" type="popupOpened"/> </af:popup>   The popup can be invoked in the normal way using showPopupBehavior or JavaScript, no special code is required there. As a further twist you can include an additional clientAttribute called preFadeDelay to define a delay before the fade itself starts (the default is 5 seconds) . To set the delay to just 2 seconds for example: <af:popup ...>   ...   <af:clientAttribute name="preFadeDelay" value="2"/>   <af:clientListener method="animateFadingPopup" type="popupOpened"/>  </af:popup> The Animation Styles  As before, we have a couple of CSS Styles which define the animation, I've put these into the skin in my case, and, as in the other articles, I've only defined the transitions for WebKit browsers (Chrome, Safari) at the moment. In this case, the fade is timed at 5 seconds in duration. .popupFadeReset {   opacity: 1; } .popupFadeAnimate {   opacity: 0;   -webkit-transition: opacity 5s ease-in-out; } As you can see here, we are achieving the fade by simply setting the CSS opacity property. The JavaScript The final part of the puzzle is, of course, the JavaScript, there are four functions, these are generic (apart from the Style names which, if you've changed above, you'll need to reflect here): The initial function invoked from the popupOpened event,  animateFadingPopup which starts a timer and provides the initial delay before we start to fade the popup. The function that applies the fade animation to the popup - initiatePopupFade. The callback function - closeFadedPopup used to reset the style class and correctly hide the popup so that it can be invoked again and again.   A utility function - findFadeContainer, which is responsible for locating the correct child component of the popup to actually apply the style to. Function - animateFadingPopup This function, as stated is the one hooked up to the popupOpened event via a clientListener. Because of when the code is called it does not actually matter how you launch the popup, or if the popup is re-used from multiple places. All usages will get the fade behavior. /**  * Client listener which will kick off the animation to fade the dialog and register  * a callback to correctly reset the popup once the animation is complete  * @param event  */ function animateFadingPopup(event) { var fadePopup = event.getSource();   var fadeCandidate = false;   //Ensure that the popup is initially Opaque   //This handles the situation where the user has dismissed   //the popup whilst it was in the process of fading   var fadeContainer = findFadeContainer(fadePopup);   if (fadeContainer != null) {     fadeCandidate = true;     fadeContainer.setStyleClass("popupFadeReset");   }   //Only continue if we can actually fade this popup   if (fadeCandidate) {   //See if a delay has been specified     var waitTimeSeconds = event.getSource().getProperty('preFadeDelay');     //Default to 5 seconds if not supplied     if (waitTimeSeconds == undefined) {     waitTimeSeconds = 5;     }     // Now call the fade after the specified time     var fadeFunction = function () {     initiatePopupFade(fadePopup);     };     var fadeDelayTimer = setTimeout(fadeFunction, (waitTimeSeconds * 1000));   } } The things to note about this function is the initial check that we have to do to ensure that the container is currently visible and reset it's style to ensure that it is.  This is to handle the situation where the popup has begun the fade, and yet the user has still explicitly dismissed the popup before it's complete and in doing so has prevented the callback function (described later) from executing. In this particular situation the initial display of the dialog will be (apparently) missing it's normal animation but at least it becomes visible to the user (and most users will probably not notice this difference in any case). You'll notice that the style that we apply to reset the  opacity - popupFadeReset, is not applied to the popup component itself but rather the dialog or panelWindow within it. More about that in the description of the next function findFadeContainer(). Finally, assuming that we have a suitable candidate for fading, a JavaScript  timer is started using the specified preFadeDelay wait time (or 5 seconds if that was not supplied). When this timer expires then the main animation styleclass will be applied using the initiatePopupFade() function Function - findFadeContainer As a component, the <af:popup> does not support styleClass attribute, so we can't apply the animation style directly.  Instead we have to look for the container within the popup which defines the window object that can have a style attached.  This is achieved by the following code: /**  * The thing we actually fade will be the only child  * of the popup assuming that this is a dialog or window  * @param popup  * @return the component, or null if this is not valid for fading  */ function findFadeContainer(popup) { var children = popup.getDescendantComponents();   var fadeContainer = children[0];   if (fadeContainer != undefined) {   var compType = fadeContainer.getComponentType();     if (compType == "oracle.adf.RichPanelWindow" || compType == "oracle.adf.RichDialog") {     return fadeContainer;     }   }   return null; }  So what we do here is to grab the first child component of the popup and check its type. Here I decided to limit the fade behaviour to only <af:dialog> and <af:panelWindow>. This was deliberate.  If  we apply the fade to say an <af:noteWindow> you would see the text inside the balloon fade, but the balloon itself would hang around until the fade animation was over and then hide.  It would of course be possible to make the code smarter to walk up the DOM tree to find the correct <div> to apply the style to in order to hide the whole balloon, however, that means that this JavaScript would then need to have knowledge of the generated DOM structure, something which may change from release to release, and certainly something to avoid. So, all in all, I think that this is an OK restriction and frankly it's windows and dialogs that I wanted to fade anyway, not balloons and menus. You could of course extend this technique and handle the other types should you really want to. One thing to note here is the selection of the first (children[0]) child of the popup. It does not matter if there are non-visible children such as clientListener before the <af:dialog> or <af:panelWindow> within the popup, they are not included in this array, so picking the first element in this way seems to be fine, no matter what the underlying ordering is within the JSF source.  If you wanted a super-robust version of the code you might want to iterate through the children array of the popup to check for the right type, again it's up to you.  Function -  initiatePopupFade  On to the actual fading. This is actually very simple and at it's heart, just the application of the popupFadeAnimate style to the correct component and then registering a callback to execute once the fade is done. /**  * Function which will kick off the animation to fade the dialog and register  * a callback to correctly reset the popup once the animation is complete  * @param popup the popup we are animating  */ function initiatePopupFade(popup) { //Only continue if the popup has not already been dismissed    if (popup.isPopupVisible()) {   //The skin styles that define the animation      var fadeoutAnimationStyle = "popupFadeAnimate";     var fadeAnimationResetStyle = "popupFadeReset";     var fadeContainer = findFadeContainer(popup);     if (fadeContainer != null) {     var fadeContainerReal = AdfAgent.AGENT.getElementById(fadeContainer.getClientId());       //Define the callback this will correctly reset the popup once it's disappeared       var fadeCallbackFunction = function (event) {       closeFadedPopup(popup, fadeContainer, fadeAnimationResetStyle);         event.target.removeEventListener("webkitTransitionEnd", fadeCallbackFunction);       };       //Initiate the fade       fadeContainer.setStyleClass(fadeoutAnimationStyle);       //Register the callback to execute once fade is done       fadeContainerReal.addEventListener("webkitTransitionEnd", fadeCallbackFunction, false);     }   } } I've added some extra checks here though. First of all we only start the whole process if the popup is still visible. It may be that the user has closed the popup before the delay timer has finished so there is no need to start animating in that case. Again we use the findFadeContainer() function to locate the correct component to apply the style to, and additionally we grab the DOM id that represents that container.  This physical ID is required for the registration of the callback function. The closeFadedPopup() call is then registered on the callback so as to correctly close the now transparent (but still there) popup. Function -  closeFadedPopup The final function just cleans things up: /**  * Callback function to correctly cancel and reset the style in the popup  * @param popup id of the popup so we can close it properly  * @param contatiner the window / dialog within the popup to actually style  * @param resetStyle the syle that sets the opacity back to solid  */ function closeFadedPopup(popup, container, resetStyle) { container.setStyleClass(resetStyle);   popup.cancel(); }  First of all we reset the style to make the popup contents opaque again and then we cancel the popup.  This will ensure that any of your user code that is waiting for a popup cancelled event will actually get the event, additionally if you have done this as a modal window / dialog it will ensure that the glasspane is dismissed and you can interact with the UI again.  What's Next? There are several ways in which this technique could be used, I've been working on a popup here, but you could apply the same approach to in-line messages. As this code (in the popup case) is generic it will make s pretty nice declarative component and maybe, if I get time, I'll look at constructing a formal Growl component using a combination of this technique, and active data push. Also, I'm sure the above code can be improved a little too.  Specifically things like registering a popup cancelled listener to handle the style reset so that we don't loose the subtle animation that takes place when the popup is opened in that situation where the user has closed the in-fade dialog.

  • Essential roles for web application team

    - by jromero
    Some friends of mine came up with an idea for a web application which we (so far) think could be great. I made the analysis and all the early stages of the development process and I'm about to start the coding. I'm talking about something that is barely a mid-level project, so I consider one developer (myself) should be enough. The thing is that we are trying to assign roles to each one of us so we can be focused on our duties and have clear our responsibilities within the team. We are a crew of four people, three of us (my friends) are business people who would do the marketing, customer relationship, management and accounting stuff and I'm basically the developer. I have in mind to get them involved into the development process by giving them documentation to write and use them as testers, all of that besides the management duties they have. Perhaps someone out there have been in the same situation, so I would appreciate if the experience is shared so we can effectively give ourselves positions in the project based on what I explained above. Which are the essential roles or the optimal team layout so the idea can be developed successfully? The question is not strictly about programming, but it's related to build a software entrepreneurship beyond the code, that is something that I'm sure plenty of us are looking. Any help is really appreciated! Regards.

  • Role of Microsoft certifications ADO.Net, ASP.Net, WPF, WCF and Career?

    - by Steve Johnson
    I am a Microsoft fan and .Net enthusiast. I want to align my career in the lines of current and future .Net technologies. I have an MCTS in ASP.Net 3.5. The question is about the continuation of certifications and my career growth and maybe a different job! I want to keep pace with future Microsoft .Net technologies. My current job however doesn't allow so.So i bid to do .Net based certifications to stay abreast with latest .Net technologies. My questions: What certifications should i follow next? I have MCTS .Net 3.5 WPF(Exam 70-502) and MCTS .Net 3.5 WCF(Exam 70-504) in my mind so that i can go for Silverlight development and seek jobs related to Silverlight development. What other steps i need to take in order to develop professional expertise in technologies such as WPF, WCF and Silverlight when my current employer is reluctant to shift to latest .Net technologies? I am sure that there are a lot of people of around here who are working with .Net technologies and they have industrial experience. I being a new comer and starter in my career need to take right decision and so i am seeking help from this community in guiding me to the right path. Expert replies are much appreciated and thanks in advance. Best Regards Steve.

  • Software Developer Interview Question - Fair or Unfair

    - by user607018
    I just phone interviewed with a company for a graduate software developer position and was asked the following questions. I should add that the company concerned are not a database vendor. How does a query optimiser work? If a database was performing badly how would you use the performance logs to find out the problem. I have asked whether they ask such questions of all candidate software developers (graduate or experienced) in a first phone interview. They replied that they like to test their candidates knowledge of database development. I want to write to the company to say that these questions are unreasonable to ask at a software developer interview and to request that my interview be done over. I would like to check the reasonableness of the following assumptions a) Those questions cannot be fairly classified as database development questions. b) I think the questions are appropriate for a DBA interview but wholly unreasonable for a software developer interview (experienced or not). c) The first question is only relevant to a database vendor. d) The second question is not fair because software developers typically don't deal with database performance logs as that is the job of the DBA. Perhaps some of you will be kind enough to comment on my assumptions or may have any other suggestions, before I write to the company.

  • How do web-developers do web-design when freelancing?

    - by Gerald Blizz
    So I got my first job recently as junior web-developer. My company creates small/medium sites for wide variety of customers: autobusiness companies, weddign agencies, some sauna websites, etcetc, hope you get my point. They don't do big serious stuff like bank systems or really big systems, it's mostly small/medium-sized websites for startups/medium sized business. My main skills are PHP/MySQL, I also know HTML and a bit of CSS/JS/AJAX. I know that good web-developer must know some backend language (like PHP/Ruby/Python) AND HTML+CSS+JS+AJAX+JQuery combo. However, I was always wondering. In my company we have web-designer. In other serious organisations I often see the same stuff: web-developers who create business-logic and web-designers, who create design. As far as I know, after designers paint design of website they give it to developers either in PSD or sliced way, and developers put it together with logic, but design is NOT created by developers. Such separation seems very good for full-time job, but I am concerned with question how do freelance web-developers do websites? Do most of them just pay freelance designers to create design for them? Or do some people do both? Reason why I ask - I plan to start some freelancing in my free time after I get good at web-development. But I don't want to create websites with great business-logic but poor design. Neither I want to let someone else create a design for me. I like web-development very much and I am doing quite good, I like design aswell, even though I am a bit lost how to study it and get better at it. But I am scared that going in both directions won't let me become expert, it seems like two totally different jobs and getting really good in both seems very hard. But I really want to do both. What should I do? Thank you!

  • Improving the speed of writing code in C#

    - by Robert Harvey
    Laugh if you want, but I used to develop substantial line-of-business applications in VB6, long before the .NET framework came along. Why, when I was your age, we used to walk two miles in the snow, uphill. Both ways... Love it or hate it, VB6 had a REPL-like feel, and a very rapid development cycle. I would like to know how to come closer to that process in C#. In VB6, I could write a function, execute it, debug it and have it fully functional in a few minutes. I am told this is how the Lisp crowd works. It's a very rapid-fire style of programming. In C# I write a function, then I write a unit test for that function (which is OK, I understand the value of that), then I right-click, run test, wait for the project to compile (takes about 10 seconds right now, which would be an eternity for a REPL loop), and get an exception. Honestly, this feels more like my junior college days, when I used to feed punch cards into a hopper and wait for a printout (exaggerating only slightly for effect). Additionally, my tendency nowadays is to make everything public while I'm testing it. Unit testing with private accessors works fine, but you can't trace through the code (unless, of course, I'm doing something wrong) while you're using them. So what I'd like to know is, what adjustments have you made to your development process in C# to streamline it, and make it possible to write and verify your code very rapidly?

  • Taking web sites offline for demonstration

    While working in software development in general, and in web development for a couple of customers it is quite common that it is necessary to provide a test bed where the client is able to get an image, or better said, a feeling for the visions and ideas you are talking about. Usually here at IOS Indian Ocean Software Ltd. we set up a demo web site on one of our staging servers, and provide credentials to the customer to access and review our progress and work ad hoc. This gives us the highest flexibility on both sides, as the test bed is simply online and available 24/7. We can update the structure, the UI and data at any time, and the client is able to view it as it suits best for her/him. Limited or lack of online connectivity But what is going to happen when your client is not capable to be online - no matter for what reasons; here are some more obvious ones: No internet connection (permanently or temporarily) Expensive connection, ie. mobile data package, stay at a hotel, etc. Presentation devices at an exhibition, ie. using tablets or iPads Being abroad for a certain time, and only occasionally online No network coverage, especially on mobile Bad infrastructure, like ie. in Third World countries Providing a catalogue on CD or USB pen drive Anyway, it doesn't matter really. We should be able to provide a solution for the circumstances of our customers. Presentation during an exhibition Recently, we had the following request from a customer: Is it possible to let us have a desktop version of ResortWork.co.uk that we can use for demo purposes at the forthcoming Ski Shows? It would allow us to let stand visitors browse the sites on an iPad to view jobs and training directory course listings. Yes, sure we can do that. Eventually, you might think why don't they simply use 3G enabled iPads for that purpose? As stated above, there might be several reasons for that - low coverage, expensive data packages, etc. Anyway, it is not a question on how to circumvent the request but to deliver a solution to that. Possible solutions... or not? We already did offline websites earlier, and even established complete mirrors of one or two web sites on our systems. There are actually several possibilities to handle this kind of request, and it mainly depends on the system or device where the offline site should be available on. Here, it is clearly expressed that we have to address this on an Apple iPad, well actually, I think that they'd like to use multiple devices during their exhibitions. Following is an overview of possible solutions depending on the technology or device in use, and how it can be done: Replication of source files and database The above mentioned web site is running on ASP.NET, IIS and SQL Server. In case that a laptop or slate runs a Windows OS, the easiest way would be to take a snapshot of the source files and database, and transfer them as local installation to those Windows machines. This approach would be fully operational on the local machine. Saving pages for offline usage This is actually a quite tedious job but still practicable for small web sites Tool based approach to 'harvest' the web site There quite some tools in the wild that could handle this job, namely wget, httrack, web copier, etc. Screenshots bundled as PDF document Not really... ;-) Creating screencast or video Simply navigate through your website and record your desktop session. Actually, we are using this kind of approach to track down difficult problems in order to see and understand exactly what the user was doing to cause an error. Of course, this list isn't complete and I'd love to get more of your ideas in the comments section below the article. Preparations for offline browsing The original website is dynamically and data-driven by ASP.NET, and looks like this: As we have to put the result onto iPads we are going to choose the tool-based approach to 'download' the whole web site for offline usage. Again, depending on the complexity of your web site you might have to check which of the applications produces the best results for you. My usual choice is to use wget but in this case, we run into problems related to the rewriting of hyperlinks. As a consequence of that we opted for using HTTrack. HTTrack comes in different flavours, like console application but also as either GUI (WinHTTrack on Windows) or Web client (WebHTTrack on Linux/Unix/BSD). Here's a brief description taken from the original website about HTTrack: HTTrack is a free (GPL, libre/free software) and easy-to-use offline browser utility. It allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. And there is an extensive documentation for all options and switches online. General recommendation is to go through the HTTrack Users Guide By Fred Cohen. It covers all the initial steps you need to get up and running. Be aware that it will take quite some time to get all the necessary resources down to your machine. Actually, for our customer we run the tool directly on their web server to avoid unnecessary traffic and bandwidth. After a couple of runs and some additional fine-tuning - explicit inclusion or exclusion of various external linked web sites - we finally had a more or less complete offline version available. A very handsome feature of HTTrack is the error/warning log after completing the download. It contains some detailed information about errors that appeared on the pages and the links within the pages that have been processed. Error: "Bad Request" (400) at link www.resortwork.co.uk/job-details_Ski_hire:tech_or_mgr_or_driver_37854.aspx (from www.resortwork.co.uk/Jobs_A_to_Z.aspx)Error: "Not Found" (404) at link www.247recruit.net/images/applynow.png (from www.247recruit.net/css/global.css)Error: "Not Found" (404) at link www.247recruit.net/activate.html (from www.247recruit.net/247recruit_tefl_jobs_network.html) In our situation, we took the records of HTTP 400/404 errors and passed them to the web development department. Improvements are to be expected soon. ;-) Quality assurance on the full-featured desktop Unfortunately, the generated output of HTTrack was still incomplete but luckily there were only images missing. Being directly on the web server we simply copied the missing images from the original source folder into our offline version. After that, we created an archive and transferred the file securely to our local workspace for further review and checks. From that point on, it wasn't necessary to get any more files from the original web server, and we could focus ourselves completely on the process of browsing and navigating through the offline version to isolate visual differences and functional problems. As said, the original web site runs on ASP.NET Web Forms and uses Postback calls for interaction like search, pagination and partly for navigation. This is the main field of improving the offline experience. Of course, same as for standard web development it is advised to test with various browsers, and strangely we discovered that the offline version looked pretty good on Firefox, Chrome and Safari, but not in Internet Explorer. A quick look at the HTML source shed some light on this, and there are conditional CSS inclusions based on the user agent. HTTrack is not acting as Internet Explorer and so we didn't have the necessary overrides for this browser. Not problematic after all in our case, but you might have to pay attention to this and get the IE-specific files explicitly. And while having a view at the source code, we also found out that HTTrack actually modifies the generated HTML output. In several occasions we discovered that <div> elements were converted into <table> constructs for no obvious reason; even nested structures. Search 'e'nd destroy - sed (or Notepad++) to the rescue During our intensive root cause analysis for a couple of HTML/CSS problems that needed some extra attention it is very helpful to be familiar with any editor that allows search and replace over multiple files like, ie. sed - stream editor for filtering and transforming text on Linux or my personal favourite Notepad++ on Windows. This allowed us to quickly fix a lot of anchors with onclick attributes and Javascript code that was addressed to ASP.NET files instead of their generated HTML counterparts, like so: grep -lr -e '.aspx' * | xargs sed -e 's/.aspx/.html?/g' The additional question mark after the HTML extension helps to separate the query string from the actual target and solved all our missing hyperlinks very fast. The same can be done in Notepad++ on Windows, too. Just use the 'Replace in files' feature and you are settled. Especially, in combination with Regular Expressions (regex). Landscape of browsers Okay, after several runs of HTML/CSS code analysis, searching and replacing some strings in a pool of more than 4.000 files, we finally had a very good match of an offline browsing experience in Firefox and Chrome on Linux. Next, we transferred that modified set of files to a Windows 8 machine for review on Firefox, Chrome and Internet Explorer 7 to 10, and a Mac mini running Mac OS X 10.7 to check the output on Safari and again on Chrome. Besides IE, for reasons already mentioned above, the results were identical. And last but not least it was about to check web site on tablets.

  • How many of you *really* surf around without JavaScript enabled? [closed]

    - by Stephen
    I've decided to rephrase the question. After some deliberation on Meta, I've realized that my question needs to be a bit more focused. The question: Should we (web developers) continue to spend effort progressively enhancing our web applications with JavaScript, ensuring that features gracefully degrade, thereby ensuring accessibility? Or should we spend that time focused on new features or other areas of development? The subtext of that question would be: How many of our customers/clients/users utilize our websites or applications with JavaScript disabled? Do you have any projects with requirements that specifically demand JavaScript functionality (almost all of mine do), and do those requirements also demand graceful degradation? For the sake of asking this question, I pulled up programmers.stackexchange.com without JavaScript enabled, and I was greeted with this message: "Programmers - Stack Exchange works best with JavaScript enabled". It was difficult to log in, albeit the site seemed to generally work okay. (I wasn't able to vote up any questions.) I think this is a satisfactory approach to development. Imagine the effort involved in making all of the site's features work with plain old HTML and server-side logic. OTOH, I wonder how many users have been alienated by this approach. We've all been trained (at least the good developers among us) to use progressive enhancement and to ensure our web applications' dynamic features degrade gracefully. Is this progressive enhancement just pissing into the wind, or do some of our customers actually utilize certain web services without JavaScript enabled? I mean, like really, not figuratively or presumptuously.

  • Best way to use GIT to maintain web application template

    - by Darren
    I am a sole developer and I have a web application template that I have created in Visual Studio. I am using GIT for source control, but only on my development machine. Presently I have a master and I create branches for new features, merging them back in to the master as I complete the features. I am at a point now where I am ready to use the template for deployments, and of course I want to continue adding new features via branching/merging. My question is: what would be the typical/recommended way for me to create application deployments based on the master? Should I clone the repository into a new directory that is for a particular web application? Or should I also use branching to do project development based on the main project? The projects would never be merged back into the master. However, it would be nice if I could merge future features into the master and have the ability to incorporate them into previously completed projects if desired. For more specific details of my environment: I am using TortoiseGIT in Windows 7, Visual Studio 2012, ASP.NET Web Pages. Obviously the main differences between deployments would simply be differing pages, CSS files and jQuery scripts. I found this post as I was writing this one. In order to do this should I clone the master repository and checkout from it?

  • Minimize useless tweaking of a numeric app

    - by Potatoswatter
    I'm developing a numeric application (nonlinear optimizer), with a zillion knobs to tweak and rising. It's not my first foray into this domain, but this time there are even more variables in the code and I'm on a tight schedule. Don't want to waste time fiddling. Days or even months can potentially be wasted adjusting variables, recompiling, and reprocessing benchmark datasets. The resulting data is viewed and trouble spots are checked. The overall quality of the solution is reported by the program but the meaning of the report could change over time. (Numeric units for the report are one thing I'm trying to nail down.) One main problem is organizing result files to identify each with specific code changes. Note taking can be a pain, is there software to help with this? Are there agreed best practices to making this kind of development cycle reliably move forward? The solver package converges to its optimal solution with mechanical determination, but I'm all too familiar with the way an excess of design decisions can mire development.

  • How to decide on a price for the project as a freelancer

    - by Shekhar_Pro
    I have seen similar question on this SE site but none comes close to a sure shot answer and many are rather subjective. So i am taking a website as an example to be more objective for you to decide its development price i should quote for the complete work.I would like to have specific figures. In past I have developed many projects for my classmates (Computer science and few .net) when i was in college and there i just arbitrarily quoted the price i will take depending on my mood and customer's ability to pay.. usually ranging from Rs.500 (about $10 USD) to Rs. 1500 (about $30 USD). I have also developed few websites but that was open-source and free. But this time impressed by my work i have got a client that wants to get a website developed similar to this: [ http://www.jeetle.in/ ]. So taking this website as an example tell me how much should i charge for complete work from designing to payment gateway implementation (Excluding the charge the payment gateway provider will take). Few information you might like to consider. I am the only developer on this project if that makes any difference. And i would be using ASP.Net and MSSQL Express for server side processing and jQuery on client. Time period for development offered is about 4 to 6 Weeks. Its like i know my work but not how much I'm worth

  • How to explain a layperson why a developer should not be interrupted while neck-deep in coding?

    - by András Szepesházi
    If you just consider the second part of my question, "Why a developer should not be interrupted while neck-deep in coding", that has been discussed a number of times by smart people. Heck, even the co-founder of SO, Joel Spolsky, wrote a blog post about "getting in the zone" and "being knocked out of the zone" and why it takes an average of 15 minutes to achieve productivity when participating in complex, software development related tasks. So I think the why has been established. What I'm interested in is how to explain all that to somebody who doesn't know beans about Beans (khmm I mean software development). How to tell the wife, or the funny guy from accounting at the workplace, or the long time friend who pings you on Skype every 30 minutes with a "Wazzzzzzup?!", that all the interruptions have a much deeper impact on your work than the obvious 30 seconds they took from your time. Obviously you can't explain it by sentences like "I have to juggle a lot of variable names in my short term memory" unless you want to be the target of blank stares or friendly abuse. I'd like to be able to explain all that to non-developers in a way that will make them clearly understand - without being offensive, elitist or too technical.

  • How can I convince my boss to invest into the developer environment?

    - by user95291
    Our boss said that developers should have fewer mistakes so the company would have money for displays, servers etc. An always mentioned example is a late firing of an underperforming colleague whose salary would have covered some of these expenses. On the other hand it happened a few times that it took a few days to free up some disk space on our servers since we can't get any more disk. The cost of mandays was definitely higher than the cost of a new HDD. Another example is that we use 14-15" notebooks for development and most of the developers get external displays after they spent one year at the company. The price of a 22-24" display is just a small fraction of a developers annual salary. Devs say that they like the company because of other reasons (high quality code, interesting projects etc.) but this kind of issues not just simply time-consuming but also demotivate them. In the point of view of the developers it seems that the boss always can find an issue in the past which they could have been done better so it's pointless to work better to get for a second display/HDD/whatever. How can I convince my boss to invest more into development environment? Is it possible to break this endless loop?
