• 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); }

• 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?

  - by David Totzke

  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? Seriously.  How hard can it be? Dave Just because I can…

• Visual Studio ALM MVP of the Year 2011

  - by Martin Hinshelwood

  For some reason this year some of my peers decided to vote for me as a contender for Visual Studio ALM MVP of the year. I am not sure what I did to deserve this, but a number of people have commented that I have a rather useful blog. I feel wholly unworthy to join the ranks of previous winners: Ed Blankenship (2010) Martin Woodward (2009) Thank you to everyone who voted regardless of who you voted for. If there was a prize for the best group of MVP’s then the Visual Studio ALM MVP would be a clear winner, as would the product group of product groups that is Visual Studio ALM Group. To use a phrase that I have learned since moving to Seattle and probably use too much: you guys are all just awesome. I have tried my best in the last year to document not only every problem that I have had with Team Foundation Server (TFS), but also to document as many of the things I am doing as possible. I have taken some of Adam Cogan’s rules to heart and when a customer asks me a question I always blog the answer and send them a link. This allows both my blog and my understanding of TFS to grow while creating a useful bank of content. The idea is that if one customer asks, all benefit. I try, when writing for my blog, to capture both the essence and the context for a problem being solved. This allows more people to benefit as they do not need to understand the specifics of an environment to gain value. I have a number of goals for this year that I think will help increase value in the community: persuade my new colleagues at Northwest Cadence to do more blogging (Steve, Jeff, Shad and Rennie) Rangers Project – TFS Iteration Automation with Willy-Peter Schaub, Bill Essary, Martin Hinshelwood, Mike Fourie, Jeff Bramwell and Brian Blackman Write a book on the Team Foundation Server API with Willy-Peter Schaub, Mike Fourie and Jeff Bramwell write more useful blog posts I do not think that these things are beyond the realms of do-ability, but we will see…

• Dutch ACEs SOA Partner Community Award Celebration

  - by JuergenKress

  When you win you need to celebrate. This was the line of thinking when I found out that I was part of a group that won the Oracle SOA Community Country Award. Well – thinking about a party is one thing, preparing it and finally having the small party is something completely different. It starts with finding a date that would be suitable for the majority of invited people. As you can imagine the SOA ACEs and ACE Directors have a busy life, that takes them places. Alongside that they are engaged with customers who want to squeeze every bit of knowledge out of them. So everybody is pretty busy (that’s what makes you an ACE). After some deliberation (and checks of international Oracle events, Trip-it, blogs and tweets) a date was chosen. Meeting on a Friday evening for some drinks is probably not a Dutch-only activity. But as some of the ACEs are self-employed they miss the companies around them to organize such events. Come the day a turn-out of almost 50% was great – although I expected some more folks . This was mainly due to some illness and work overload. Luckily the mini-party got going, (alcoholic) beverages were consumed, food was appreciated, a decent picture was made (see below) and all had a good chat and hopefully a good time. (Above from left to right: Eric Elzinga, Andreas Chatziantoniou, Mike van Aalst, Edwin Biemond) All in all a nice evening and certainly a "meeting" which can be repeated.  For the full article please visit Andreas's blog Want to organize a local SOA & BPM community?

Because Oracle ACE-dom inherently is a stamp of not only expertise, but a unique ability to make that expertise useful to others. Plus, they're a group of "fine blokes" (UK. subjects, educate me: is that really a word?)Perhaps if you're not able to catch one of these sessions, you will be able to see the applicable ACE in action elsewhere, at a conference or user group meeting near you.

• Setup a Autoreply Only Account

  - by dabrain

  For some very good reason you might would like to setup a 'autoreply' only account, without storing the incoming mail into a mailbox. If not already done, create an account via Delegated Admin Gui or commadmin Commandline Tool. Example: /opt/sun/comms/da/bin/commadmin user create -D admin -d vmdomain.tld -w enigma -F Mike -l    mparis -L Paris -W tester -E Mike[email protected] -S mail -H mars.vmdomain.tld Setup mailDeliveryOption to autoreply mode only, so no email will be stored in the user mailbox, skip this step if you want incoming emails stored in the mailbox. ldapmodify -D "cn=Directory Manager" -w enigma -f /tmp/modfile [/tmp/modfile] dn: uid=mparis,ou=People,o=vmdomain.tld,o=red changetype: modify replace: mailDeliveryOption mailDeliveryOption: autoreply Setup mailSieveRuleSource with the autoreply text and 'do-not-reply' From address. The "Thank you ..." part becomes the subject. The next string in quotes is the body part of the message. The ":hours 0" denotes that we want a reply sent for every message. Finally,  the \n is used because of the wanted newlines in the body. ldapmodify -D "cn=Directory Manager" -w enigma -f /tmp/addfile [/tmp/addfile] dn: uid=mparis,ou=People,o=vmdomain.tld,o=red changetype: modify add: mailSieveRuleSource mailSieveRuleSource: require "vacation"; vacation :hours 0 :reply :from "do-not-reply   @domain.com" :subject "Thank you for contacting webpost" "Your Mail is being review   ed.\nTo access contact information please visit : http://www.domain.com \nPlease do    not reply to this e-mail as it is an automated response on your mail being accessed   .\n\nPublic Respose Unit.\n"

• Getting Unity 3D working on legacy Nvidia card

  - by user69545

  I installed the latest nVIDIA drivers for my FX5500 card. I understand that the X server version does not officially support this driver or card but was wondering what I can do to get compiz running. I have researched for hours on this issue but cannot come up with an answer for myself. I might be doing all this for nothing but I wanted to at least try. Here is the output of my test: mike@mike-linux-box:~$ /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.35 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no So I was wondering what is the "Not Blacklisted" test? Is this the Nouveau Blacklisting? nVIDIA driver did that automatically. Does this need to be removed? Any help would be appreciated. I just want to run compiz effects. Thanks.

• Dynamic (C# 4.0) &amp; Var in a nutshell.

  - by mbcrump

  A Var is static typed - the compiler and runtime know the type. This can be used to save some keystrokes. The following are identical. Code Snippet var mike = "var demo"; Console.WriteLine(mike.GetType());  //Returns System.String   string mike2 = "string Demo"; Console.WriteLine(mike2.GetType()); //Returns System.String A dynamic behaves like an object, but with dynamic dispatch. The compiler doesn’t know anything about it at compile time. Code Snippet dynamic duo = "dynamic duo"; Console.WriteLine(duo.GetType()); //System.String //duo.BlowUp(); //A dynamic type does not know if this exist until run-time. Console.ReadLine(); To further illustrate this point, the dynamic type called “duo” calls a method that does not exist called BlowUp(). As you can see from the screenshot below, the compiler is reporting no errors even though BlowUp() does not exist. The program will compile fine. It will however throw a runtimebinder exception after it hits that line of code in runtime. Let’s try the same thing with a Var. This time, we get a compiler error that says BlowUp() does not exist. This program will not compile until we add a BlowUp() method.  I hope this helps with your understand of the two. If not, then drop me a line and I’ll be glad to answer it.
