  • Do print and bookmark links really work?

    - by Joseph Mastey
    It seems to be common on the web to provide users with some visual element on the page to either print or bookmark a page. This is all well and good (and probably doesn't hurt for the most part), but I question its effectiveness at causing the intended behavior. Is there any evidence to suggest that this causes an increase in bookmarking/printing behavior? Similarly, is there any evidence that users will use this method rather than the browser's default interface for the functions? I am really looking for user research with actual results, rather than anecdotes to answer this question. Thanks, Joseph Mastey

  • What's the deal with URLs for Yandex.Metrica not prepended with "http"?

    - by sharptooth
    The description of Yandex.Metrica explicitly says that URLs like //mc.yandex.ru/metrika/watch.js (no http: in front) that the web site owner has to insert into his pages are not erroneous. So for example this code: <img src="//mc.yandex.ru/watch/00000" style="position:absolute; left:-9999px;" alt="" /> is claimed to be okay. However the code validator thinks such URLs are not okay and I'd rather make the validator happy so that noone breaks the code later trying to "fix" it. Why are these URLs not prepended with http:? What happens if I actually prepend them with http:?

  • Would using AJAX only "Add to Cart" buttons be wise?

    - by Alex Erwin
    I want to AJAX enable all of my Add To Cart buttons because search engine bots are indexing these and not paying attention to my robots file or site map. I just don't want to loose potential customers. I have seen a number of top sites using heavily JavaScript support content, including Amazon, is it OK to follow the trend? The rest of my site progressively degrades, but I would really like to implement this because of the benefits to the customer (instant satisfaction), my infrastructure (constant page rebuilds), and allowing me to use SEO tools to optimize without the tool picking up thousands of "Add to Cart" widgets in my catalog. Thanks

  • Dynamic virtual host configuration in Apache

    - by Kostas Andrianopoulos
    I want to make a virtual host in Apache with dynamic configuration for my websites. For example something like this would be perfect. <VirtualHost *:80> AssignUserId $domain webspaces ServerName $subdomain.$domain.$tld ServerAdmin admin@$domain.$tld DocumentRoot "/home/webspaces/$domain.$tld/subdomains/$subdomain" <Directory "/home/webspaces/$domain.$tld/subdomains/$subdomain"> .... </Directory> php_admin_value open_basedir "/tmp/:/usr/share/pear/:/home/webspaces/$domain.$tld/subdomains/$subdomain" </VirtualHost> $subdomain, $domain, $tld would be extracted from the HTTP_HOST variable using regex at request time. No more loads of configuration, no more apache reloading every x minutes, no more stupid logic. Notice that I use mpm-itk (AssignUserId directive) so each virtual host runs as a different user. I do not intend to change this part. Since now I have tried: - mod_vhost_alias but this allows dynamic configuration of only the document root. - mod_macro but this still requires the arguments of the vhost to be declared explicitly for each vhost. - I have read about mod_vhs and other modules which store configuration in a SQL or LDAP server which is not acceptable as there is no need for configuration! Those 3 necessary arguments can be generated at runtime. - I have seen some Perl suggestions like this, but as the author states $s->add_config would add a directive after every request, thus leading to a memory leak, and $r->add_config seems not to be a feasible solution.

  • Transposition - the success story of VB6 migration

    - by Visual WebGui
    Since all of you VB developers in the present or past would probably find it hard to believe that the old VB code can be migrated and modernized into the latest .NET based HTML5 without having to rewrite the application I am feeling I need to write another post on our migration solution. Hopefully, after reading this and the previous post you will be able to understand the different approach of our solution which already helps organizations around the world move away from the constraints of VB6 and...(read more)

  • Learning to implement dynamically typed language compiler

    - by TriArc
    I'm interested in learning how to create a compiler for a dynamically typed language. Most compiler books, college courses and articles/tutorials I've come across are specifically for statically typed languages. I've thought of a few ways to do it, but I'd like to know how it's usually done. I know type inferencing is a pretty common strategy, but what about others? Where can I find out more about how to create a dynamically typed language? Edit 1: I meant dynamically typed. Sorry about the confusion. I've written toy compilers for statically typed languages and written some interpreters for dynamically typed languages. Now, I'm interested in learning more about creating compilers for a dynamically typed language. I'm specifically experimenting with LLVM and since I need to specify the type of every method and argument, I'm thinking of ways to implement a dynamically typed language on something like LLVM.

  • Can resizing images with css be good?

    - by Echo
    After reading Is CSS resizing of images still a bad idea?, I thought of a similar question. (too similar? should this be closed?) Lets say you need to use 10 different product image sizes throughout your website and you have 20k-30k different product images, should you use 10 different files for each image size? or maybe 5 different files and use css to resize the other 5? Would there ever be combination that would be good? Or should you always make separate image files? If you use css to resize them, you will save on storage (in GBs) but you will have slight increase in bandwidth and slower loading images(but if images are cached, and you show both sizes of the image would you use less bandwidth and have faster loads?) (But of course you wouldn't want to use css to resize images for mobile sites.)

  • unit testing variable state explicit tests in dynamically typed languages

    - by kris welsh
    I have heard that a desirable quality of unit tests is that they test for each scenario independently. I realised whilst writing tests today that when you compare a variable with another value in a statement like: assertEquals("foo", otherObject.stringFoo); You are really testing three things: The variable you are testing exists and is within scope. The variable you are testing is the expected type. The variable you are testing's value is what you expect it to be. Which to me raises the question of whether you should test for each of these implicitly so that a test fail would occur on the specific line that tests for that problem: assertTrue(stringFoo); assertTrue(stringFoo.typeOf() == "String"); assertEquals("foo", otherObject.stringFoo); For example if the variable was an integer instead of a string the test case failure would be on line 2 which would give you more feedback on what went wrong. Should you test for this kind of thing explicitly or am i overthinking this?

  • Change CSS EMs to Percentage Automatically.

    - by Zachary Brown
    I cheated on a small site I was working on and used a site builder (Web Dwarf by Virtual Mechanics) to save time. I didn't realize it at the time, but this builder specifies the width, height and positions using CSS EMs. Is there an automated tool out there that will read through the CSS and convert each EM to a percentage so it will display correctly on wide screens as well? Any help would be great! Thanks. Here is the CSS: http://pastebin.de/14055

  • How to get search engines to properly index an ajax driven search page

    - by Redtopia
    I have an ajax-driven search page that will allow users to search through a large collection of records. Each search result points to index.php?id=xyz (where xyz is the id of the record). The initial view does not have any records listed, and there is no interface that allows you to browse through all records. You can only conduct a search. How do I build the page so that spiders can crawl each record? Or is there another way (outside of this specific search page) that will allow me to point spiders to a list of all records. FYI, the collection is rather large, so dumping links to every record in a single request is not a workable solution. Outputting the records must be done in multiple requests. Each record can be viewed via a single page (eg "record.php?id=xyz"). I would like all the records indexed without anything indexed from the sitemap that shows where the records exist, for example: <a href="/result.php?id=record1">Record 1</a> <a href="/result.php?id=record2">Record 2</a> <a href="/result.php?id=record3">Record 3</a> <a href="/seo.php?page=2">next</a> Assuming this is the correct approach, I have these questions: How would the search engines find the crawl page? Is it possible to prevent the search engines from indexing the words "Record 1", etc. and "next"? Can I output only the links? Or maybe something like:

  • Conditional attribute in XML - most concise solution?

    - by Lech Rzedzicki
    I am tasked with setting up conditional profiling - a method of tagging chunks of XML with an attribute, which will then be used as a conditional value to extract subset of that XML. Have a look at another definition/example: DITA profiling The XML is documents that are equivalent to printed books - i.e. documents that are often looked at by a human, even if indirectly. Therefore I am looking at a few requirements here: 1. keeping the value list brief - so it doesn't affect the readability of the document 2. be able to process with standard XML tools - a space-separated list inside an attribute is still probably fine, but I'd rather not use too much regexp for this 3. be obvious for various users, including 3rd parties, which content goes where 4. Be easy to maintain going forward Therefore one easy solution is: The problem with this: 1. As the list grows the value of the attribute can be a bit verbose 2. One needs to explicitly state every value even if it's a scenario of this vs everything else Therefore I am also looking at other approaches such as: 1. Using + and - modifiers, Apache htaccess style to override the default cascading of profiling - by default all content goes everywhere and if we want to exclude a bit we just say "-kindle". It does require parsing the whole tree, is not supported by editing tools and one needs to regexp the attribute value a bit deeper... 2. Using an intermediate file to define groups of values such as "other" or "non-print", example of this in DITA. It allows concise XML as well as different grouping and values for each document but it does create a certain level of abstraction which may make it a little less obvious for a 3rd party? Altogether, if you received such XML and were tasked to process it, which option you'd rather receive? If you have any experiences like that, even in an unrelated areas such a builds, don't hesitate to comment!

  • Modify MDT wizard to automate computer naming

    - by Jeramy
    I originally posted this question to StackOverflow, but upon further consideration it might be more appropriate here. Situation: I am imaging new systems using MDT Lite-Touch. I am trying to customize the wizard to automate the naming of new systems so that they include a prefix "AG-", a department code which is selected from a drop-down box in the wizard page (eg. "COMM"), and finally the serial number of the computer being imaged, so that my result in this case would be "AG-COMM-1234567890" Status: I have banged away at this for a while but my Google searches have not turned up answers, my trial-and-error is not producing useful error messages and I think I am missing some fundamentals of how to get variables from the wizard page into the variables used by the lite-touch wizard. Progress: I first created the HTML page which I will include below and added a script to the page to concatenate the pieces into a variable called OSDComputername which, for testing, I could output in a msgbox and get to display correctly. The problem with this is I don't know how to trigger the script then assign it to the OSDComputername variable that is used throughout the rest of the Light-Touch process. I changed the script to a function and added it to DeployWiz_Initization.vbs then used the Initialization field in WDS to call it. I'll include the function below. The problem with this is I would get "Undefined Variable" for OSDComputername and I am not sure it is pulling the data from the HTML correctly. I tried adding the scripting into the customsettings.ini file after the "OSDComputername=" This resulted in the wizard just outputting my code in text as the computer name. I am now trying adding variables to "Properties=" (eg.DepartmentName) in the customsettings.ini, pulling thier value from the HTML Form and setting that value to the variable in my function in DeployWiz_Initization.vbs and calling them after "OSDComputername=" in the fashion "OSDComputername="AG-" & %DepartmentName%" in customsettings.ini I am rebuilding right now and will see how this goes Any help would be appreciated. The HTML page: <HTML> <H1>Configure the computer name.</H1> <span style="width: 95%;"> <p>Please answer the following questions. Your answers will be used to formulate the computer's name and description.</p> <FORM NAME="TestForm"> <p>Departmental Prefix: <!-- <label class=ErrMsg id=DepartmentalPrefix_Err>* Required (MISSING)</label> --> <SELECT NAME="DepartmentalPrefix_Edit" class=WideEdit> <option value="AADC">AADC</option> <option value="AEM">AEM</option> <option value="AIP">AIP</option> <option value="COM">COM</option> <option value="DO">DO</option> <option value="DSOC">DSOC</option> <option value="EDU">EDU</option> <option value="EPE">EPE</option> <option value="ITN">ITN</option> <option value="LA">LA</option> <option value="OAP">OAP</option> <option value="SML">SML</option> </SELECT> </p> <p><span class="Larger">Client's Net<u class=larger>I</u>D:</span> <INPUT NAME="ClientNetID" TYPE="TEXT" ID="ClientNetID" SIZE="15"></p> <p>Building: <!-- <label class=ErrMsg id=Building_Err>* Required (MISSING)</label> --> <SELECT NAME="Building_Edit" class=WideEdit> <option value="Academic Surge Facility A">Academic Surge Facility A</option> <option value="Academic Surge Facility B">Academic Surge Facility B</option> <option value="Caldwell">Caldwell</option> <option value="Kennedy">Kennedy</option> <option value="Roberts">Roberts</option> <option value="Warren">Warren</option> </SELECT> </p> <p> <span class="Larger">Room <u class=larger>N</u>umber:</span> <input type=text id="RoomNumber" name=RoomNumber size=15 /> </p> </FORM> </span> </HTML> The Function: Function SetComputerName OSDComputerName = "AG-" & oEnvironment.Item("DepartmentalPrefix_Edit") ComputerDescription = oEnvironment.Item("DepartmentalPrefix_Edit") & ", " & oEnvironment.Item("ClientNetID") & ", " & oEnvironment.Item("RoomNumber") & " " & oEnvironment.Item("Building_Edit") End Function

  • Winamp question: Generating 'dynamic playlists' from file playlists -OR- mass-tagging by file playli

    - by Daddy Warbox
    I'm trying to think of a way to do this. I sort my songs into a variety of playlists corresponding to different 'moods' I might have as I listen to them, and some songs fit for more than one kind of mood (e.g. a jazz song might be 'stylish' and 'emotional', or something to that effect). I also give them star ratings for a general sort of opinion about them. I want to be able to filter and sort my media library by the moods I want or don't want, as well as by star rating. Anyone have a good way to do something like this? I can't seem to use Winamp's dynamic playlists to generate lists from existing filesystem playlists (e.g. songs in a given .m3u files). Hand-tagging files with Winamp's tag editor is a royal pain. It's trouble enough just giving a star rating and sorting into playlists as is. If there is there a way to mass tag songs within each playlist with mood words to allow me to create dynamic playlists, I'd be fine (for now). It'd be nice if I could do this via some kind of hotkey for each song, too. I'm looking to see if I can use a macro program or something to do that, though. Thanks in advance. P.S: Alternatively, would something like Foobar have functions like this? Note: Italics are recent edits.

  • ZenGallery: a minimalist image gallery for Orchard

    - by Bertrand Le Roy
    There are quite a few image gallery modules for Orchard but they were not invented here I wanted something a lot less sophisticated that would be as barebones and minimalist as possible out of the box, to make customization extremely easy. So I made this, in less than two days (during which I got distracted a lot). Nwazet.ZenGallery uses existing Orchard features as much as it can: Galleries are just a content part that can be added to any type The set of photos in a gallery is simply defined by a folder in Media Managing the images in a gallery is done using the standard media management from Orchard Ordering of photos is simply alphabetical order of the filenames (use 1_, 2_, etc. prefixes if you have to) The path to the gallery folder is mapped from the content item using a token-based pattern The pattern can be set per content type You can edit the generated gallery path for each item The default template is just a list of links over images, that get open in a new tab No lightbox script comes with the module, just customize the template to use your favorite script. Light, light, light. Rather than explaining in more details this very simple module, here is a video that shows how I used the module to add photo galleries to a product catalog: Adding a gallery to a product catalog You can find the module on the Orchard Gallery: https://gallery.orchardproject.net/List/Modules/Orchard.Module.Nwazet.ZenGallery/ The source code is available from BitBucket: https://bitbucket.org/bleroy/nwazet.zengallery

  • JS and CSS caching issue: possibly .htaccess related

    - by adamturtle
    I've been using the HTML5 Boilerplate for some web projects for a while now and have noticed the following issue cropping up on some sites. My CSS and JS files, when loaded by the browser, are being renamed to things like: ce.52b8fd529e8142bdb6c4f9e7f55aaec0.modernizr-1,o7,omin,l.js …in the case of modernizr-1.7.min.js The pattern always seems to add ce. or cc. in front of the filename. I'm not sure what's causing this, and it's frustrating since when I make updates to those files, the same old cached file is being loaded. I have to explicitly call modernizr-1.7.min.js?v=2 or something similar to get it to re-cache. I'd like to scrap it altogether but it still happens even when .htaccess is empty. Any ideas? Is anyone else experiencing this issue?

  • C++ difference between "char *" and "char * = new char[]"

    - by nashmaniac
    So, if I want to declare an array of characters I can go this way char a[2]; char * a ; char * a = new char[2]; Ignoring the first declaration, the other two use pointers. As far as I know the third declaration is stored in heap and is freed using the delete operator . does the second declaration also hold the array in heap ? Does it mean that if something is stored in heap and not freed can be used anywhere in a file like a variable with file linkage ? I tried both third and second declaration in one function and then using the variable in another but it didn't work, why ? Are there any other differences between the second and third declarations ?
