• ASP.NET MVC 2 InputExtensions different on server than local machine

  - by Mike

  Hi everyone, So this is kind of a crazy problem to me, but I've had no luck Googling it. I have an ASP.NET MVC 2 application (under .NET 4.0) running locally just fine. When I upload it to my production server (under shared hosting) I get Compiler Error Message: CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'TextBoxFor' and no extension method 'TextBoxFor' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?) for this code: <%= this.Html.TextBoxFor(person => person.LastName) %> This is one of the new standard extension methods in MVC 2. So I wrote some diagnostic code: System.Reflection.Assembly ass = System.Reflection.Assembly.GetAssembly(typeof(InputExtensions)); Response.Write("From GAC: " + ass.GlobalAssemblyCache.ToString() + "<br/>"); Response.Write("ImageRuntimeVersion: " + ass.ImageRuntimeVersion.ToString() + "<br/>"); Response.Write("Version: " + System.Diagnostics.FileVersionInfo.GetVersionInfo(ass.Location).ToString() + "<br/>"); foreach (var method in typeof(InputExtensions).GetMethods()) { Response.Write(method.Name + "<br/>"); } running locally (where it works fine), I get this as output: From GAC: True ImageRuntimeVersion: v2.0.50727 Version: File: C:\Windows\assembly\GAC_MSIL\System.Web.Mvc\2.0.0.0__31bf3856ad364e35\System.Web.Mvc.dll InternalName: System.Web.Mvc.dll OriginalFilename: System.Web.Mvc.dll FileVersion: 2.0.50217.0 FileDescription: System.Web.Mvc.dll Product: Microsoft® .NET Framework ProductVersion: 2.0.50217.0 Debug: False Patched: False PreRelease: False PrivateBuild: False SpecialBuild: False Language: Language Neutral CheckBox CheckBox CheckBox CheckBox CheckBox CheckBox CheckBoxFor CheckBoxFor CheckBoxFor Hidden Hidden Hidden Hidden HiddenFor HiddenFor HiddenFor Password Password Password Password PasswordFor PasswordFor PasswordFor RadioButton RadioButton RadioButton RadioButton RadioButton RadioButton RadioButtonFor RadioButtonFor RadioButtonFor TextBox TextBox TextBox TextBox TextBoxFor TextBoxFor TextBoxFor ToString Equals GetHashCode GetType and when running on the production server (where it fails), I see: From GAC: True ImageRuntimeVersion: v2.0.50727 Version: File: C:\Windows\assembly\GAC_MSIL\System.Web.Mvc\2.0.0.0__31bf3856ad364e35\System.Web.Mvc.dll InternalName: System.Web.Mvc.dll OriginalFilename: System.Web.Mvc.dll FileVersion: 2.0.41001.0 FileDescription: System.Web.Mvc.dll Product: Microsoft® .NET Framework ProductVersion: 2.0.41001.0 Debug: False Patched: False PreRelease: False PrivateBuild: False SpecialBuild: False Language: Language Neutral CheckBox CheckBox CheckBox CheckBox CheckBox CheckBox Hidden Hidden Hidden Hidden Hidden Hidden Password Password Password Password RadioButton RadioButton RadioButton RadioButton RadioButton RadioButton TextBox TextBox TextBox TextBox ToString Equals GetHashCode GetType note that "TextBoxFor" is not present (hence the error).

• Myfaces extensionfilter overriding renderkit? (Tree2 component)

  - by Mike

  I've pulled in the tree2 component (from Tomahawk 1.1.9). Had used the simpler Tree component on previous projects, and this one just looks a bit nicer. Running on websphere 6.1.x and set the server side flag that's needed (com.ibm.ws.webcontainer.invokefilterscompatibility=true) and set the extensionfilter accordingly. Everything's good, and works as expected. Here's the issue: - on a page being included on this one (just some typical footer type info with NO myfaces widgets), there's some embedded html that's getting flagged with warnings in the systemout console). These look like org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 475. Surroundings: 'span id="tile:footr:viewFragm'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 479. Surroundings: 'a id="tile:footr:viewFragment'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 492. Surroundings: 'a id="tile:footr:viewFragment'. The problem isn't necessarily with the html (which should be cleaned up regardless :-). IF I don't include myfaces, I don't get these warning messages with the default ibm jsf renderer (using jsf 1.1 still). Obviously, IBM's implementation is a bit more lax than myFaces. The page has nothing to do with myfaces at all. The reason for needing the extension filter is that it needs (for the Tree2 anyways, I know it does more for file upload) to intercept requests and then stick some .js includes on the page. Investigated this a bit, and I've included this filter in my web.xml, but it is NO longer fronting the faces servlet. So, the filter is instantiated at startup, but is never executed. Since the filter isn't in place, I've had to hard code in the includes for the 2 .js files into my page Now, the tree2 gets rendered properly, AND I'm not getting the warnings from above, because with the extentionfilter not being called, its using the IBM renderkit ;-) I'm a bit concerned that when the extension filter is in place, everything is being rendered by myFaces, rather than IBM's renderkit (i.e. All I want is myfaces/tomahawk to render the tree2 only, and let the ri do everything else) Can anyone confirm this? When you use myfaces/tomahawk, is it doing all the rendering for the whole application, or just the page any tomahawk widget is on? Thanks for any thoughts on this mike

• In GWT I'd like to load the main page on www.domain.com and a dynamic page on www.domain.com/xyz - I

  - by Mike Brecht

  Hi, I have a question for which I'm sure there must a simple solution. I'm writing a small GWT application where I want to achieve this: www.domain.com : should serve the welcome page www.domain.com/xyz : should serve page xyz, where xyz is just a key for an item in a database. If there is an item associated with key xyz, I'll load that and show a page, otherwise I'll show a 404 error page. I was trying to modify the web.xml file accordingly but I just couldn't make it work. I could make it work with an url-pattern if the key in question is after another /, for example: www.domain.com/search/xyz. However, I'd like to have the key xyz directly following the root / (http://www.domain.com/xyz). Something like <servlet-mapping> <servlet-name>main</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> doesn't seem to work as I don't know how to address the main page index.html (as it's not an actual servlet) which will then load my main GWT module. I could make it work with a bad work around (see below): Redirecting a 404 exception to index.html and then doing the look up in the main entry point, but I'm sure that's not the best practice, also for SEO purposes. Can anyone give me a hint on how to configure the web.xml with GWT for my purpose? Thanks a lot. Mike Work-around via 404: Web.xml: <web-app> <error-page> <exception-type>404</exception-type> <location>/index.html</location> </error-page> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> </web-app> index.html -- Main Entry point -- onModuleLoad(): String path = Window.Location.getPath(); if (path == null || path.length() == 0 || path.equalsIgnoreCase("/") || path.equalsIgnoreCase("/index.html")) { ... // load main page } else { lookup(path.substring(1)); // that's key xyz

• How do I set libavcodec to use 4:2:2 chroma when encoding MPEG-2 4:2:2 profile?

  - by Mike Pollitt

  I have a project using libavcodec (ffmpeg). I'm using it to encode MPEG-2 video at 4:2:2 Profile, Main Level. I have the pixel format PIX_FMT_YUV422P selected in the AVCodecContext, however the video output I'm getting has all the colours wrong, and looks to me like the encoder is incorrectly reading the buffers as though it thinks it is 4:2:0 chroma rather than 4:2:2. Here's my codec setup: // // AVFormatContext* _avFormatContext previously defined as mpeg2video // // // Set up the video stream for output // AVVideoStream* _avVideoStream = av_new_stream(_avFormatContext, 0); if (!_avVideoStream) { err = ccErrWFFFmpegUnableToAllocateStream; goto bail; } _avCodecContext = _avVideoStream->codec; _avCodecContext->codec_id = CODEC_ID_MPEG2VIDEO; _avCodecContext->codec_type = CODEC_TYPE_VIDEO; // // Set up required parameters // _avCodecContext->rc_max_rate = _avCodecContext->rc_min_rate = _avCodecContext->bit_rate = src->_avCodecContext->bit_rate; _avCodecContext->flags = CODEC_FLAG_INTERLACED_DCT; _avCodecContext->flags2 = CODEC_FLAG2_INTRA_VLC | CODEC_FLAG2_NON_LINEAR_QUANT; _avCodecContext->qmin = 1; _avCodecContext->qmax = 1; _avCodecContext->rc_buffer_size = _avCodecContext->rc_initial_buffer_occupancy = 2000000; _avCodecContext->rc_buffer_aggressivity = 0.25; _avCodecContext->profile = 0; _avCodecContext->level = 5; _avCodecContext->width = f->GetWidth(); // f is a private Frame class with width, height properties etc. _avCodecContext->height = f->GetHeight(); _avCodecContext->time_base.den = 25; _avCodecContext->time_base.num = 1; _avCodecContext->gop_size = 12; _avCodecContext->max_b_frames = 2; _avCodecContext->pix_fmt = PIX_FMT_YUV422P; if (_avFormatContext->oformat->flags & AVFMT_GLOBALHEADER) { _avCodecContext->flags |= CODEC_FLAG_GLOBAL_HEADER; } if (av_set_parameters(_avFormatContext, NULL) < 0) { err = ccErrWFFFmpegUnableToSetParameters; goto bail; } // // Set up video codec for encoding // AVCodec* _avCodec = avcodec_find_encoder(_avCodecContext->codec_id); if (!_avCodec) { err = ccErrWFFFmpegUnableToFindCodecForOutput; goto bail; } if (avcodec_open(_avCodecContext, _avCodec) < 0) { err = ccErrWFFFmpegUnableToOpenCodecForOutput; goto bail; } A screengrab of the resulting video frame can be seen at http://ftp.limeboy.com/images/screen_grab.png (the input was standard colour bars). I've checked by outputting debug frames to TGA format at various points in the process, and I can confirm that it is all fine and dandy up until the point that libavcodec encodes the frame. Any assistance most appreciated! Cheers, Mike.

• question about book example - Java Concurrency in Practice, Listing 4.12

  - by mike

  Hi, I am working through an example in Java Concurrency in Practice and am not understanding why a concurrent-safe container is necessary in the following code. I'm not seeing how the container "locations" 's state could be modified after construction; so since it is published through an 'unmodifiableMap' wrapper, it appears to me that an ordinary HashMap would suffice. EG, it is accessed concurrently, but the state of the map is only accessed by readers, no writers. The value fields in the map are syncronized via delegation to the 'SafePoint' class, so while the points are mutable, the keys for the hash, and their associated values (references to SafePoint instances) in the map never change. I think my confusion is based on what precisely the state of the collection is in the problem. Thanks!! -Mike Listing 4.12, Java Concurrency in Practice, (this listing available as .java here, and also in chapter form via google) /////////////begin code @ThreadSafe public class PublishingVehicleTracker { private final Map<String, SafePoint> locations; private final Map<String, SafePoint> unmodifiableMap; public PublishingVehicleTracker( Map<String, SafePoint> locations) { this.locations = new ConcurrentHashMap<String, SafePoint>(locations); this.unmodifiableMap = Collections.unmodifiableMap(this.locations); } public Map<String, SafePoint> getLocations() { return unmodifiableMap; } public SafePoint getLocation(String id) { return locations.get(id); } public void setLocation(String id, int x, int y) { if (!locations.containsKey(id)) throw new IllegalArgumentException( "invalid vehicle name: " + id); locations.get(id).set(x, y); } } // monitor protected helper-class @ThreadSafe public class SafePoint { @GuardedBy("this") private int x, y; private SafePoint(int[] a) { this(a[0], a[1]); } public SafePoint(SafePoint p) { this(p.get()); } public SafePoint(int x, int y) { this.x = x; this.y = y; } public synchronized int[] get() { return new int[] { x, y }; } public synchronized void set(int x, int y) { this.x = x; this.y = y; } } ///////////end code

• Agile and Scrum burning me down please help me figuring out the truth

  - by jadook

  hi all, in the last while I installed MS-TFS 2008 then started to get myself prepared to use Agile Process Guidance template shipped with the TFS. with little googling I passed through Mike Cohn materials: I watched his conference in youtube "sponsored by google: http://www.youtube.com/watch?v=fb9Rzyi8b90 http://www.youtube.com/watch?v=jeT0pOVg0EI Read his book "Agile Estimating and Planning" Watching the video series in his website: http://www.mountaingoatsoftware.com/presentations-tag/video-recorded I was very happy while absorbing and eating the techniques he is using with the teams and how agile and scrum is such a great software process/methodology until I saw Mike answering a question regarding an architect role and talking about the requirements document... at that point everything start falling apart due to the following: Last year I had been assigned to make full analysis "including requirements gathering" for big project "very high priority project". within 2 months of hardwork, dedication and commitment I delivered the whole analysis with full satisfaction of the customer and my BOSS and ZERO amendments. Later on, the project entered the architecting, development ... phases. due to the fact that the system included many competitive and exciting features I requested patenting it and its going in the process... so imagine you are the kind of person who used to love facing all kind of challenges and returning with excellent experience and results for the stakeholders and yourself, How fairly agile and scrum processes will credit and admit your talent and passion while the scrum master/coach treat the team as one unit that accomplish user stories and converge through trial and error approach??!!!! with that dark thoughts about agile and scrum I found many people "anti agile" and on top of them is "Crispin Rogers Johnson": http://agile-crispin.blogspot.com/ that guy made anti statement for everything Mike Cohn used to talk about. I really don't know what to do next! so any guidance will be appreciated. Thanks,

• passing value of index number to different php file.

  - by tooepic

  hi, i am a php beginner and have a question for you please. i have a text file with list of first and last names like this: john,smith sam,lewis david,davidson mike,anderson in my sort.php file, it sorts that name list by first name in ascending order with index number, which will display like this: 1. david,davidson 2. john,smith 3. mike,anderson 4. sam,lewis also, in that sort.php file, there's a form for input type=text where you can type index number and a button to delete that index number entered in that text field: <form action="deletename.php" method="post"> <table> <tr valign="top"> <td>Delete: <input type="text" size="2" name="indexnumber" /> </td> <td> <div align="left"> <input type="submit" name="delete" value="Delete" /> </div> </td> </tr> </table> </form> now the question...is there anything i can do in that form to send the value of that index number i entered in the text field? in other word...if i enter 3, what can i do to that form to send the value "mike,anderson" to deletename.php? thanks in advance.

• MySQL: Request to select the last 10 send/received messages to/by different users

  - by Yako malin

  I want to select the 10 last messages you received OR you sent TO different users. For example the results must be shown like that: 1. John1 - last message received 04/17/10 3:12 2. Thomy - last message sent 04/16/10 1:26 3. Pamela - last message received 04/12/10 3:51 4. Freddy - last message received 03/28/10 9:00 5. Jack - last message sent 03/20/10 4:53 6. Tom - last message received 02/01/10 7:41 ..... Table looks like: CREATE TABLE `messages` ( `id` int(11) NOT NULL AUTO_INCREMENT, `time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `sender` int(11) DEFAULT NULL, `receiver` int(11) DEFAULT NULL, `content` text ) I think Facebook (and the iPhone) use this solution. When you go to your mail box, you have the last messages received/sent grouped by Users (friends). So I will take an example. If I have theses messages (THEY ARE ORDERED YET): **Mike** **Tom** **Pam** Mike Mike **John** John Pam **Steve** **Bobby** Steve Steve Bobby Only Message with ** should be returned because they are the LAST messages I sent/received By User. In fact I want the last message of EACH discussion. What is the solution?

While currently on mike.xml, I want BACK to link to "dano.xml" and NEXT linked to "steve.xml"...etc..and have it dynamically change when on a different page based on the nodes around it. I want to do this because I may add and change the list as I go along, so I don't want to have to manually re-link everything. How can I obtain this? Sorry I am new to XSLT, so please explain with solution if possible! Thanks in advance!

• What is the proper way to set my drawable directories to support the new Dell Streak without losing support for older devices?

  - by emmby

  This seems to be a widespread problem. I have the following drawable directories: drwxr-xr-x 18 mike staff 612 Feb 4 17:28 drawable/ drwxr-xr-x 51 mike staff 1734 Feb 4 17:32 drawable-nodpi/ drwxr-xr-x 44 mike staff 1496 Feb 4 17:30 drawable-normal-mdpi/ My xml drawable resources are in drawable. My resources intended for the large-mdpi (Dell Streak) and normal-hdpi (Droid, Nexus, Incredible, etc.) are all in drawable-nodpi. My resources for normal-mdpi (older phones like the G1) are in drawable-normal-mdpi. Unfortunately, the normal-hdpi phones like the Droid are pulling their resources from drawable-normal-mdpi instead of from drawable-nodpi. This is likely because of the rules in How Android Finds the Best-matching Resource. So the question is, how do I provide support for large-mdpi devices like the Streak along with normal-hdpi devices like the Droid, as well as normal-mdpi devices like the G1? The simplest solution would probably be to make two copies of my large resources, one in normal-hdpi for the droid and one in large-mdpi for the streak, but i'd like to avoid duplicating all of these resources. Update Per Mayra's suggestion, I could make an alias for every resource. However, there are a lot of resources I'd have to make aliases for, which would make maintenance a nightmare going forward, so I'm hoping for another solution.

• NLP with greatly contrained input and abilities

  - by Mike F

  Hat in hand here. I'm a seasoned developer and I would be grateful for a bit of help. I don't have time to read or digest long intricate discussions on theoretical concepts around NLP (or go get my PHD). That said, I have read a few and it's a damn interesting field. The problem is I need real world solutions, for real world products, in real world time frames. The problem I'm having is right now I'm not sure what the right questions are to ask to get started implementing. I believe this is mostly related to vocabulary. I'll read somewhere, a blog post, a forum post, a whitepaper, and it says, I'm doing flooping with the blargy blarg method, and I go google flooping and blargy blarg, and I get references to more obscurity. It seemingly never ends. So, my question is multiphased. First, more generally, how do I become passingly educated on this quickly? Just in time educated. I only need to know what I need to know to take the next step. I've spent 20 years writing code. Explain quick. I'll get it. (I mean provide a reference to something that explains quickly of course). I'm happy to read the right book, but I don't want to read a book where I read the chapter introduction that explains what floopy floop is and then skip over the rest of the chapter with examples of floopy flooping (because now I get what it is). I also don't want to read a book that goes into too much detail with theoretical underpinnings or history. For example, the Jurafsky book seems like way more than I need: http://www.amazon.com/gp/product/0131873210. But I will read it if this is the right book to read. (It's also dang expensive!) I need the root node of the expedited learning tree here, if you will. Point me in the right direction and I'll be quite grateful. I'm expecting quite a lot of firehose drinking - I just need the right firehose. Second, what I need to do is take a single sentence, with a very reduced vocabulary, and get a grammar tree (sorry if this is the wrong terminology) that I can do something with. I know I could easily write this command line input style in c in a more conventional manner, but I need it to be way better than that. But I don't need a chatterbot either. What I'm doing needs to live in a constrained environment. I can't use Python (unfortunately). I can't ship with gigabytes of corpuses. I need any libraries I use to be in c/c++. If I have to write this myself, I will. Hopefully, it will be achievable considering the reduced problem set. Maybe, probably, that's just naive. If so, let me know. :-) Thanks in advance - Mike

• Chaining CSS classes in IE6 - Trying to find a jQuery solution?

  - by Mike Baxter

  Right, perhaps I ask the impossible? I consider myself fairly new to Javscript and jQuery, but that being said, I have written some fairly complex code recently so I am definitely getting there... however I am now possed with a rather interesting issue at my current freelance contract. The previous web coder has taken a Grid-960 approach to the HTML and as a result has used chained classes to style many of the elements. The example below is typical of what can be found in the code: <div class='blocks four-col-1 orange highlight'>Some content</div> And in the css there will be different declarations for: (not actual css... but close enough) .blocks {margin-right:10px;} .orange {background-image:url(someimage.jpg);} .highlight {font-weight:bold;} .four-col-1 {width:300px;} and to make matters worse... this is in the CSS: .blocks.orange.highlight {background-colour:#dd00ff;} Anyone not familiar with this particular bug can read more on it here: http://www.ryanbrill.com/archives/multiple-classes-in-ie/ it is very real and very annoying. Without wanting to go into the merrits of not chaining classes (I told them this, but it is no longer feasible to change their approach... 100 hand coded pages into a 150 page website, no CMS... sigh) and without the luxury of being able to change the way these blocks are styled... can anyone advise me on the complexity and benefits between any of my below proposed approaches or possible other options that would adequately solve this problem. Potential Solution 1 Using conditional comments I am considering loading a jquery script only for IE6 that: Reads the class of all divs in a certain section of the page and pushes to an array creates empty boxes off screen with only one of the classes applied at a time Reads the applied CSS values for each box Re-applies these styles to the individual box, somehow bearing in mind the order in which they are called and overwriting conflicting instructions as required Potential Solution 2 read the class of all divs in a certain section of the page and push to an array Scan the document for links to style sheets Ajax grab the stylesheets and traverse looking for matching names to those in class array Apply styles as needed Potential Solution 3 Create an IE6 only stylesheet containing the exact style to be applied as a unique name (ie: class='blocks orange highlight' becomes class='blocks-orange-highlight') Traverse the document in IE6 and convert all spaces in class declarations to hyphens and reapply classes based on new style name Summary: Solution 1 allows the people at this company to apply any styles in the future and the script will adjust as needed. However it does not allow for the chained style to be added, only the individual style... it is also processor intensive and time consuming, but also the most likely to be converted into a plugin that could be used the world over Solution 2 is a potential nightmare to code. But again will allow for an endless number of updates without breaking Solution 3 will require someone at the companty to hardcode the new styles every time they make a change, and if they don't, IE6 will break. Ironically the site, whilst needing to conform to IE6 in a limited manner, does not need to run wihtout javascript (they've made the call... have JS or go away), so consider all jQuery and JS solutions to be 'game on'. Did I mention how much i hate IE6? Anyway... any thoughts or comments would be appreciated. I will continue to develop my own solution and if I discover one that can be turned into a jQuery plugin I will post it here in the comments. Regards, Mike.

• Android - determine specific locations (X,Y coordinates) on a Bitmap on different resolutions?

  - by Mike

  My app that I am trying to create is a board game. It will have one bitmap as the board and pieces that will move to different locations on the board. The general design of the board is square, has a certain number of columns and rows and has a border for looks. Think of a chess board or scrabble board. Before using bitmaps, I first created the board and boarder by manually drawing it - drawLine & drawRect. I decided how many pixels in width the border would be based on the screen width and height passed in on "onSizeChanged". The remaining screen I divided by the number of columns or rows I needed. For examples sake, let's say the screen dimensions are 102 x 102. I may have chosen to set the border at 1 and set the number of rows & columns at 10. That would leave 100 x 100 left (reduced by two to account for the top & bottom border, as well as left/right border). Then with columns and rows set to 10, that would leave 10 pixels left for both height and width. No matter what screen size is passed in, I store exactly how many pixels in width the boarder is and the height & width of each square on the board. I know exactly what location on the screen to move the pieces to based on a simple formula and I know exactly what cell a user touched to make a move. Now how does that work with bitmaps? Meaning, if I create 3 different background bitmaps, once for each density, won't they still be resized to fit each devices screen resolution, because from what I read there were not just 3 screen resolutions, but 5 and now with tablets - even more. If I or Android scales the bitmaps up or down to fit the current devices screen size, how will I know how wide the border is scaled to and the dimensions of each square in order to figure out where to move a piece or calculate where a player touched. So far the examples I have looked at just show how to scale the overall bitmap and get the overall bitmaps width and height. But, I don't see how to tell how many pixels wide or tall each part of the board would be after it was scaled. When I draw each line and rectangle myself based in the screen dimensions from onSizeChanged, I always know these dimensions. If anyone has any sample code or a URL to point me to that I can a read about this with bitmaps, I would appreciate it. Thanks, --Mike BTW, here is some sample code (very simplified) on how I know the dimensions of my game board (border and squares) no matter the screen size. Now I just need to know how to do this with the board as a bitmap that gets scaled to any screen size. @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { intScreenWidth = w; intScreenHeight = h; // Set Border width - my real code changes this value based on the dimensions of w // and h that are passed in. In other words bigger screens get a slightly larger // border. intOuterBorder = 1; /** Reserve part of the board for the boardgame and part for player controls & score My real code forces this to be square, but this is good enough to get the point across. **/ floatBoardHeight = intScreenHeight / 4 * 3; // My real code actually causes floatCellWidth and floatCellHeight to // be equal (Square). floatCellWidth = (intScreenWidth - intOuterBorder * 2 ) / intNumColumns; floatCellHeight = (floatBoardHeight - intOuterBorder * 2) / intNumRows; super.onSizeChanged(w, h, oldw, oldh); }

• Is this text wrapping technique possible in CSS and jQuery?

  - by alex

  I have built a sliding text thing for a website. http://www.solomonadventures.com/~new/adventure-tours/seafari-tours/ The background contains the menu (on the right hand side), and when it originally loads, I have placed an element to make the text look like it is wrapping around the menu. Now, I have a sliding text thing I was asked to implement. The buttons to use it are currently in the top left corner. My question is, when I slide the content down, am I able to somehow make the text still wrap around it? This is all I have thought of so far (all with trade offs) Make the text appear beneath the menu - no need to wrap Make the text as narrow to the beginning of the menu - no need to wrap Manually place placeholders in the text that make it line break so it appears to wrap - not elegant (site uses a CMS too) Is there any jQuery selector I could write that would allow me to select the paragraph from top (once slid to the top) or the top most text node (so I could do an after() to place a new placeholder element to force it to wrap?) Any other solutions? Many thanks.

• allowing 2 VM's to communicate RED HAT 64 bit

  - by ????? ????????

  My physical PC is running 2 VMs on virtualbox. Both of the VM's are linux 64 bit. I am going through this tutorial: http://www.cyberciti.biz/faq/rhel-centos-fedoracore-linux-network-card-configuration/ in order to expose both of their IP's so that they can speak to each other. Mike Schwager November 25, 2009 at 10:55 pm Whoops! In section 3, you forgot about editing /etc/hosts. I believe RedHat comes complete with the system’s host ip address set up in /etc/hosts. Don’t forget to give it a look. I agree with Mike because after I looked into the /etc/hosts files, it has just default localhost stuff in it. How should I reconfigure the hosts file?

• Calculate geometric mean in Excel

  - by Libby

  I have some email network data in Excel as a edgelist meaning I have columns Vertex1, Vertex2, and then N columns of properties of that edge like how many emails were sent from one person to another. For each row in the data, Vertex1 is the source of a message, and Vertex2 is the target, so edges are directed. Here's some sample data Vertex1 Vertex2 nMessages Bob Cindy 12 Cindy Bob 3 Bob Mike 11 Cindy Mike 1 I'm trying to calculate a geometric mean of the form gm = sqrt[(# of edges ij)*(# of edges ji)] So gm for Bob and Cindy is gm = sqrt[(messages from Bob to Cindy)*(messages from Cindy to Bob)] or sqrt(12*3) = 6. Is there a way to make that a formula in Excel?

• Not able to delete file from server with permissions of 644 via PHP script

  - by letseatfood

  I am trying to delete JPEG files that were uploaded to the server via FTP. The files are uploaded and written with permissions of 644. The owner and group of the upload directory are mike and mike. I have tried changing the owner and group to www-data, but that does not seem to work. I am trying to delete the files with a PHP script using unlink(). This works on the production server (which is a hosting service), but not my development server, which is a LAMP setup. This leads me to believe it has something to do with permissions on my development server.

• How to add correct cancellation when downloading a file with the example in the samples of the new P

  - by Mike

  Hello everybody, I have downloaded the last samples of the Parallel Programming team, and I don't succeed in adding correctly the possibility to cancel the download of a file. Here is the code I ended to have: var wreq = (HttpWebRequest)WebRequest.Create(uri); // Fire start event DownloadStarted(this, new DownloadStartedEventArgs(remoteFilePath)); long totalBytes = 0; wreq.DownloadDataInFileAsync(tmpLocalFile, cancellationTokenSource.Token, allowResume, totalBytesAction => { totalBytes = totalBytesAction; }, readBytes => { Log.Debug("Progression : {0} / {1} => {2}%", readBytes, totalBytes, 100 * (double)readBytes / totalBytes); DownloadProgress(this, new DownloadProgressEventArgs(remoteFilePath, readBytes, totalBytes, (int)(100 * readBytes / totalBytes))); }) .ContinueWith( (antecedent ) => { if (antecedent.IsFaulted) Log.Debug(antecedent.Exception.Message); //Fire end event SetEndDownload(antecedent.IsCanceled, antecedent.Exception, tmpLocalFile, 0); }, cancellationTokenSource.Token); I want to fire an end event after the download is finished, hence the ContinueWith. I slightly changed the code of the samples to add the CancellationToken and the 2 delegates to get the size of the file to download, and the progression of the download: return webRequest.GetResponseAsync() .ContinueWith(response => { if (totalBytesAction != null) totalBytesAction(response.Result.ContentLength); response.Result.GetResponseStream().WriteAllBytesAsync(filePath, ct, resumeDownload, progressAction).Wait(ct); }, ct); I had to add the call to the Wait function, because if I don't, the method exits and the end event is fired too early. Here are the modified method extensions (lot of code, apologies :p) public static Task WriteAllBytesAsync(this Stream stream, string filePath, CancellationToken ct, bool resumeDownload = false, Action<long> progressAction = null) { if (stream == null) throw new ArgumentNullException("stream"); // Copy from the source stream to the memory stream and return the copied data return stream.CopyStreamToFileAsync(filePath, ct, resumeDownload, progressAction); } public static Task CopyStreamToFileAsync(this Stream source, string destinationPath, CancellationToken ct, bool resumeDownload = false, Action<long> progressAction = null) { if (source == null) throw new ArgumentNullException("source"); if (destinationPath == null) throw new ArgumentNullException("destinationPath"); // Open the output file for writing var destinationStream = FileAsync.OpenWrite(destinationPath); // Copy the source to the destination stream, then close the output file. return CopyStreamToStreamAsync(source, destinationStream, ct, progressAction).ContinueWith(t => { var e = t.Exception; destinationStream.Close(); if (e != null) throw e; }, ct, TaskContinuationOptions.ExecuteSynchronously, TaskScheduler.Current); } public static Task CopyStreamToStreamAsync(this Stream source, Stream destination, CancellationToken ct, Action<long> progressAction = null) { if (source == null) throw new ArgumentNullException("source"); if (destination == null) throw new ArgumentNullException("destination"); return Task.Factory.Iterate(CopyStreamIterator(source, destination, ct, progressAction)); } private static IEnumerable<Task> CopyStreamIterator(Stream input, Stream output, CancellationToken ct, Action<long> progressAction = null) { // Create two buffers. One will be used for the current read operation and one for the current // write operation. We'll continually swap back and forth between them. byte[][] buffers = new byte[2][] { new byte[BUFFER_SIZE], new byte[BUFFER_SIZE] }; int filledBufferNum = 0; Task writeTask = null; int readBytes = 0; // Until there's no more data to be read or cancellation while (true) { ct.ThrowIfCancellationRequested(); // Read from the input asynchronously var readTask = input.ReadAsync(buffers[filledBufferNum], 0, buffers[filledBufferNum].Length); // If we have no pending write operations, just yield until the read operation has // completed. If we have both a pending read and a pending write, yield until both the read // and the write have completed. yield return writeTask == null ? readTask : Task.Factory.ContinueWhenAll(new[] { readTask, writeTask }, tasks => tasks.PropagateExceptions()); // If no data was read, nothing more to do. if (readTask.Result <= 0) break; readBytes += readTask.Result; if (progressAction != null) progressAction(readBytes); // Otherwise, write the written data out to the file writeTask = output.WriteAsync(buffers[filledBufferNum], 0, readTask.Result); // Swap buffers filledBufferNum ^= 1; } } So basically, at the end of the chain of called methods, I let the CancellationToken throw an OperationCanceledException if a Cancel has been requested. What I hoped was to get IsFaulted == true in the appealing code and to fire the end event with the canceled flags and the correct exception. But what I get is an unhandled exception on the line response.Result.GetResponseStream().WriteAllBytesAsync(filePath, ct, resumeDownload, progressAction).Wait(ct); telling me that I don't catch an AggregateException. I've tried various things, but I don't succeed to make the whole thing work properly. Does anyone of you have played enough with that library and may help me? Thanks in advance Mike

• How Hard Can It Be?

  I mean seriously.  Let’s imagine for a moment that by some stroke of luck or genius or cosmic accident that you come to be the owner of sex.com.  You’d think you had won the lottery.  That would be like having a license to print money.  I mean really.  Sex is the most searched term on the entire Internet.  Even without any SEO you’d think that your site would show up on the first page of results on Google. You would think that; and you’d be wrong.  At least in the case of the current owners of that domain name anyways.  The details can be found here but suffice it to say that Escom LLC has managed to fuck it up.  They’ve been forced into bankruptcy by their creditors.  Something doesn’t smell quite right with the whole thing.  Some guy named Mike Mann (please God, don’t let it be this Mike Mann) is an investor in all three creditors.  WTF?
