  • Implementing a kext that intercepts file system usage.

    - by UraN
    Hi, how do most of antivirus software block file system io in case of an infected file? I suppose all the magic resides in some custom kext to do that. Can anyone point me to some topics on this? Some working example would also be great. I've read apple docs about kext development, but mostly it's all about hardware drivers and i could not find what i need. Thanx.

  • Should I HttpCombine Google Jquery Hosted File?

    - by chobo2
    Hi I am using something called HttpCombiner: http://code.msdn.microsoft.com/HttpCombiner An HTTP handler that combines multiple CSS, Javascript or URL into one response for faster page load. It can combine, compress and cache response which results in faster page load and better scalability of web application It's a good practice to use many small Javascript and CSS files instead of one large Javascript/CSS file for better code maintainability, but bad in terms of website performance. Although you should write your Javascript code in small files and break large CSS files into small chunks but when browser requests those javascript and css files, it makes one Http request per file. Every Http Request results in a network roundtrip form your browser to the server and the delay in reaching the server and coming back to the browser is called latency. So, if you have four javascripts and three css files loaded by a page, you are wasting time in seven network roundtrips. Within USA, latency is average 70ms. So, you waste 7x70 = 490ms, about half a second of delay. Outside USA, average latency is around 200ms. So, that means 1400ms of waiting. Browser cannot show the page properly until Css and Javascripts are fully loaded. So, the more latency you have, the slower page loads. You can reduce the wait time by using a CDN. Read my previous blog post about using CDN. However, a better solution is to deliver multiple files over one request using an HttpHandler that combines several files and delivers as one output. So, instead of putting many or tag, you just put one and one tag, and point them to the HttpHandler. You tell the handler which files to combine and it delivers those files in one response. This saves browser from making many requests and eliminates the latency. This Http Handler reads the file names defined in a configuration and combines all those files and delivers as one response. It delivers the response as gzip compressed to save bandwidth. Moreover, it generates proper cache header to cache the response in browser cache, so that, browser does not request it again on future visit. Now I am wondering since it can handle adding links should I put in it the jquery file? The reason I am not sure is if it gets combined with my other files I think I might close the advantages of it being hosted on googles servers such as caching(my thinking is if it gets combined it will look different so even if a user has it in it's cache I am not sure if it will use the one for the cahce or not). So should I combine it or only the finals that I am using locally?

  • posting form with file upload

    - by Jan
    I am having trouble with uploading a file when using jquery. I have the following HTML in a form. <fieldset> <ul> <li> <div class="field"><input size="35" type="file" name="formFile" id="formFile"/></div> </li> <li> <div class="field"><input size="35" type="text" name="formFileName" id="formFileName" /></div> </li> </ul> </fieldset> To post the data I am using $('#myForm').ajaxForm( When I post the data and the recieved data contains some javascript, the javascript is not recognised. I expected the javscriptcode to run when the data is recieved, but it happens to early. The results indicates that $ or jquery could not be found. If I remove the name attribute from the input type=file element, there are no errors, but that is not the correct solution. How could this happen?

  • pass string or data of local file between viewcontrollers

    - by Jonathan
    In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack: http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?

  • BATCH - wait for executable to finish before starting next result

    - by user3697573
    I'm pretty much a noob at this, so any help is appreciated. I'm trying to run the video transcoding executable REDline on all .R3D files in a given folder. REDline only accepts single files, which is the issue. I finally got it to search recursively for the files I need, but my problem is the search function passes the next result to REDline before the first one is finished transcoding. I have the search results that need to run in a variable inside REDline. Here's the code: for /r D:\folder\ %%a in (*) do ( "C:/Program Files/REDCINE-X PRO 64-bit/REDLine.exe" --exportPreset "Prores_Intermediate" --i "%%~dpnxa" --useRSX 2 --masterRMDFolder "" -s 0 -e 95 ) After about .7 seconds, REDline reports 'received stop message from client'. I don't think this is a REDline error, as I have been able to transcode single files successfully. Thanks.

  • Why does visual studio think js file is a cs file?

    - by divitiae
    I have a ASP.NET solution in Visual Studio 2008 and I added a file identical to http://plugins.jquery.com/files/jquery.cookie.js.txt named jquery.cookie.js in a subfolder of my project containing other javascript files and Visual Studio is treating it as a C# file, giving me errors like CS1012: Too many characters in character literal and Semicolon after method or accesssor block is not valid. Why?

  • How do I set a resource file to non-embedded

    - by themaninthesuitcase
    In Visual studio 2008 is it possible to have a resource file that is included as a separate file after compilation rather than as an embedded resource. This is to enable small changes to be rolled out more easily. I have tried build options of Resource, None, Compile and also copy local on and off for most of these. However when ever I try access the resource at run time I get a cannot find resource exception. Is this actually possible or am I wasting my time?

  • CopyFileEx and 8.3 file names

    - by Lobuno
    Suppose you have 2 files in the same directory: New File Name.txt and NewFil~1.txt If you use CopyFileEx to copy both files to the same destination, maintaining the same names, you will end up having only ONE file (the second one replaces the first one) which can be sometimes not a good thing. Any workaround for this behavior?

  • Can IE Developer Tools be configured to 'see' a window that is less than full screen in size?

    - by user2795930
    I have used Developer Tools for IE for over 2 years, so I have some good experience with the tool. But the window that I need to debug now is less than a full screen in size and cannot be made larger. (Just imagine a large window that is approximately 2/3's of your full screen, but cannot be enlarged so that it is full screen). So when I try to utilize Developer Tools to debug the window, it doesn't work. It is as if Developer Tools tries to look at the full screen which is displayed behind my window that is displayed on the screen. Is there any way to make Developer Tools 'see' a window that is less than full screen in size and sits on top of another screen / web page?

  • how to add emblem to windows file icon?

    - by Wifi Cordon
    Hello, I want to know how to add some sort of emblem or badge to a specific file. Just like drop box does to a specific file when it is doing a sync. I found that the guys from drop box are able to do that on linux by using libnautilus package. But I need to do so on windows and haven't been able to find an answer. Will the solution change from one windows version to other? best regards

  • Is there a quality, file-size, or other benefit to JPEG sizes being multiples of 8px or 16px?

    - by davebug
    The JPEG compression encoding process splits a given image into blocks of 8x8 pixels, working with these blocks in future lossy and lossless compressions. [source] It is also mentioned that if the image is a multiple 1MCU block (defined as a Minimum Coded Unit, 'usually 16 pixels in both directions') that lossless alterations to a JPEG can be performed. [source] I am working with product images and would like to know both if, and how much benefit can be derived from using multiples of 16 in my final image size (say, using an image with size 480px by 360px) vs. a non-multiple of 16 (such as 484x362). In this example I am not interested in further alterations, editing, or recompression of the final image. To try to get closer to a specific answer where I know there must be largely generalities: Given a 480x360 image that is 64k and saved at maximum quality in Photoshop [example]: Can I expect any quality loss from an image that is 484x362 What amount of file size addition can I expect (for this example, the additional space would be white pixels) Are there any other disadvantages to growing larger than the 8px grid? I know it's arbitrary to use that specific example, but it would still be helpful (for me and potentially any others pondering an image size) to understand what level of compromise I'd be dealing with in breaking the non-8px grid. The key issue here is a debate I've had is whether 8-pixel divisible images are higher quality than images that are not divisible by 8-pixels.

  • settings file vs app.config

    - by fearofawhackplanet
    I'm not really understanding the interaction/differences between settings and config files. If I add an entry to the settings file, it gets added to the app.config as well. Does this mean that changing the value in the app.config will update the settings? If not, how do I update settings in a live application? What's the general purpose of using a settings file instead of putting things directly in app.config?
