  • How does MySQL 5.5 and InnoDB on Linux use RAM?

    - by Loren
    Does MySQL 5.5 InnoDB keep indexes in memory and tables on disk? Does it ever do it's own in-memory caching of part or whole tables? Or does it completely rely on the OS page cache (I'm guessing that it does since Facebook's SSD cache that was built for MySQL was done at the OS-level: https://github.com/facebook/flashcache/)? Does Linux by default use all of the available RAM for the page cache? So if RAM size exceeds table size + memory used by processes, then when MySQL server starts and reads the whole table for the first time it will be from disk, and from that point on the whole table is in RAM? So using Alchemy Database (SQL on top of Redis, everything always in RAM: http://code.google.com/p/alchemydatabase/) shouldn't be much faster than MySQL, given the same size RAM and database?

  • How to abort shutdown in Windows (XP|Vista) programatically?

    - by Piskvor
    I want to be able to detect and abort OS shutdown from my application, preferably by using the Windows API. I know that it is possible to do this manually using the command shutdown -a In the worst case, I could ShellExecute this, but I was wondering if there was a better way. Also, how do I find out programatically that the OS is about to shut down, via the Win32 API?

  • How to create curved Text on a Bitmap?

    - by TooFat
    I am currently dynamically creating a bitmap and using the graphics object from the string from the bitmap to Draw a string on it like so. System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); graph.DrawString(text, font, brush, new System.Drawing.Point(0, 0)); This returns a rectangle shaped bitmap with the string written straight across from left to right. I would like to also be able to draw the string in the shape of a rainbow. How can I do this?

  • [Python] How can I speed up unpickling large objects if I have plenty of RAM?

    - by conradlee
    It's taking me up to an hour to read a 1-gigabyte NetworkX graph data structure using cPickle (its 1-GB when stored on disk as a binary pickle file). Note that the file quickly loads into memory. In other words, if I run: import cPickle as pickle f = open("bigNetworkXGraph.pickle","rb") binary_data = f.read() # This part doesn't take long graph = pickle.loads(binary_data) # This takes ages How can I speed this last operation up? Note that I have tried pickling the data both in using both binary protocols (1 and 2), and it doesn't seem to make much difference which protocol I use. Also note that although I am using the "loads" (meaning "load string") function above, it is loading binary data, not ascii-data. I have 128gb of RAM on the system I'm using, so I'm hoping that somebody will tell me how to increase some read buffer buried in the pickle implementation.

  • How to keep historic details of modification in a database (Audit trail)?

    - by mada
    I'm a J2EE developer & we are using hibernate mapping with a PostgreSQL database. We have to keep track of any changes occurs in the database, in others words all previous & current values of any field should be saved. Each field can be any type (bytea, int, char...) With a simple table it is easy but we a graph of objects things are more difficult. So we have, speaking in a UML point of view, a graph of objects to store in the database with every changes & the user. Any idea or pattern how to do that?

  • jQuery detect visible but hidden elements

    - by IP
    This seems like it should be fairly easy - but I can't find the right selector for it According to the docs (http://api.jquery.com/hidden-selector/ and http://api.jquery.com/visible-selector/)... Elements can be considered hidden for several reasons: An ancestor element is hidden, so the element is not shown on the page. What I want to detect is "this element is visible, but is contained in a hidden parent". Ie, if I made the parent visible, this element would also be visible.

  • Image storage as a service

    - by Samuel
    Google App Engine provides a image API for storing / retrieving images. We are currently not in a position to deploy our application on top of App Engine because of limitations in the java frameworks (jboss seam 2.2.0) we are using to build our j2ee application. We would eventually want to deploy our production application on top of Google App Engine, but what are the short term options (java based open source products) which provides comparable functionality to Google App Engine's Image API and will have an easier migration path at a later point in time.

  • Generating Running Sum of Ratings in SQL

    - by Koobz
    I have a rating table. It boils down to: rating_value created +2 april 3rd -5 april 20th So, every time someone gets rated, I track that rating event in the database. I want to generate a rating history/time graph where the rating is the sum of all ratings up to that point in time on a graph. I.E. A person's rating on April 5th might be select sum(rating_value) from ratings where created <= april 5th The only problem with this approach is I have to run this day by day across the interval I'm interested in. Is there some trick to generating a running total using this sort of data? Otherwise, I'm thinking the best approach is to create a denormalized "rating history" table alongside the individual ratings.

  • Difference between library and native library

    - by Alvin
    Could anyone tell me the difference between library and native library in terms of java? I found the word "native library" in the following line: Type 1 - drivers that implement the JDBC API as a mapping to another data access API, such as ODBC. Drivers of this type are generally dependent on a native library, which limits their portability. The JDBC-ODBC Bridge driver is an example of a Type 1 driver. which you can found here

  • Hide public method used to help test a .NET assembly

    - by ChrisW
    I have a .NET assembly, to be released. Its release build includes: A public, documented API of methods which people are supposed to use A public but undocumented API of other methods, which exist only in order to help test the assembly, and which people are not supposed to use The assembly to be released is a custom control, not an application. To regression-test it, I run it in a testing framework/application, which uses (in addition to the public/documented API) some advanced/undocumented methods which are exported from the control. For the public methods which I don't want people to use, I excluded them from the documentation using the <exclude> tag (supported by the Sandcastle Help File Builder), and the [EditorBrowsable] attribute, for example like this: /// <summary> /// Gets a <see cref="IEditorTransaction"/> instance, which helps /// to combine several DOM edits into a single transaction, which /// can be undone and redone as if they were a single, atomic operation. /// </summary> /// <returns>A <see cref="IEditorTransaction"/> instance.</returns> IEditorTransaction createEditorTransaction(); /// <exclude/> [EditorBrowsable(EditorBrowsableState.Never)] void debugDumpBlocks(TextWriter output); This successfully removes the method from the API documentation, and from Intellisense. However, if in a sample application program I right-click on an instance of the interface to see its definition in the metadata, I can still see the method, and the [EditorBrowsable] attribute as well, for example: // Summary: // Gets a ModelText.ModelDom.Nodes.IEditorTransaction instance, which helps // to combine several DOM edits into a single transaction, which can be undone // and redone as if they were a single, atomic operation. // // Returns: // A ModelText.ModelDom.Nodes.IEditorTransaction instance. IEditorTransaction createEditorTransaction(); // [EditorBrowsable(EditorBrowsableState.Never)] void debugDumpBlocks(TextWriter output); Questions: Is there a way to hide a public method, even from the meta data? If not then instead, for this scenario, would you recommend making the methods internal and using the InternalsVisibleTo attribute? Or would you recommend some other way, and if so what and why? Thank you.

  • Python 3.1 twitter post with installed library,

    - by Andrew
    I'd like to be able to post twitter messages from python 3.0. None of the twitter API I have looked at support python 3.1. Since the post proceedure only requires this : JSON: curl -u username:password -d status="your message here" http://api.twitter.com/1/statuses/update.json I was wondering if it is possible with the standard libraries to format this so a message could be sent. My head says it should be possible.

  • What is the exact rule of jQuery's animate() parameters?

    - by Jian Lin
    jQuery 1.4.2's animate() API spec is .animate( properties, [ duration ], [ easing ], [ callback ] ) but it seems that we can supply duration, callback, and no easing .animate({left: '+= 100'}, 600, doThis) and it will work. But if we supply easing and callback and no duration .animate({left: '+=100'}, 'swing', doThis) then the easing won't be taken into effect. So what exactly is the API supposed to be?

  • use jQuery to get 'true size' of image without removing the class

    - by jon3laze
    I am using Jcrop on an image that is resized with css for uniformity. JS <script type="text/javascript"> $(window).load(function() { //invoke Jcrop API and set options var api = $.Jcrop('#image', { onSelect: storeCoords, trueSize: [w, h] }); api.disable(); //disable until ready to use //enable the Jcrop on crop button click $('#crop').click(function() { api.enable(); }); }); function storeCoords(c) { $('#X').val(c.x); $('#Y').val(c.y); $('#W').val(c.w); $('#H').val(c.h); }; </script> HTML <body> <img src="/path/to/image.jpg" id="image" class="img_class" alt="" /> <br /> <span id="crop" class="button">Crop Photo</span> <span id="#X" class="hidden"></span> <span id="#Y" class="hidden"></span> <span id="#W" class="hidden"></span> <span id="#H" class="hidden"></span> </body> CSS body { font-size: 13px; width: 500px; height: 500px; } .image { width: 200px; height: 300px; } .hidden { display: none; } I need to set the h and w variables to the size of the actual image. I tried using the .clone() manipulator to make a copy of the image and then remove the class from the clone to get the sizing but it sets the variables to zeros. var pic = $('#image').clone(); pic.removeClass('image'); var h = pic.height(); var w = pic.width(); It works if I append the image to an element in the page, but these are larger images and I would prefer not to be loading them as hidden images if there is a better way to do this. Also removing the class, setting the variables, and then re-adding the class was producing sporadic results. I was hoping for something along the lines of: $('#image').removeClass('image', function() { h = $(this).height(); w = $(this).width(); }).addClass('image'); But the removeClass function doesn't work like that :P
