• How to identify a PDF classification problem?

  - by burtonic

  We are crawling and downloading lots of companies' PDFs and trying to pick out the ones that are Annual Reports. Such reports can be downloaded from most companies' investor-relations pages. The PDFs are scanned and the database is populated with, among other things, the: Title Contents (full text) Page count Word count Orientation First line Using this data we are checking for the obvious phrases such as: Annual report Financial statement Quarterly report Interim report Then recording the frequency of these phrases and others. So far we have around 350,000 PDFs to scan and a training set of 4,000 documents that have been manually classified as either a report or not. We are experimenting with a number of different approaches including Bayesian classifiers and weighting the different factors available. We are building the classifier in Ruby. My question is: if you were thinking about this problem, where would you start?

• Mass Delete Using Gridview with Checkboxes

  This sample shows how to use a Gridview to delete multiple records all at once, having marked them with a Checkbox, and clicking one button, external to the Gridview, to delete them all As usual, here, we're using the Northwind Database. If you want to try this on your own Northwind database, adhere to this word of caution - "BACK IT UP FIRST". You will be making multiple deletes, so in order to get it back to the original state, you must make a backup and then restore afterwards. Remember too, that you will need to substitute your own Web.Config connectionstring entry for "YourNorthwindString" in the sample code

• How is this "interface"-like structure/pattern called?

  - by Sebastian Negraszus

  Let's assume we have an XmlDoc class that contains basic functionality for dealing with an XML data structure and saving/loading data to/from a file. Now we have several subclasses, A, B and C. They all inherit from XmlDoc and add component-specific methods for setting and getting lots of data. They are like "interfaces" but also add an implementation for the signatures. Finally, we have an ABCDoc class that joins all the "interfaces" via virtual multiple inheritence and adds some ABCDoc-specific stuff, such as using XMLDoc-methods to set an appropriate doc type. We may also have an ADoc class for only saving A data. How is this pattern called? "Interface" is not really the right word since interfaces usually do not contain an implementation. Bonus points for C++ code conventions.

• Overview of XSLT

  - by kaleidoscope

  XSLT (Extensible Stylesheet Language Transformations) is a declarative- XMLbased language used for the transformation of XML documents into other XML documents. Using XSLT , the original document does not changed; rather, a new document is created based on the content of an existing one. XSLT is developed by the World Wide Web Consortium (W3C).   Using XSLT we can transform source xml file into another xml file, word file or Excel file.    XSLT Functions : -   There are the following built - in XSLT functions :   Name Description current() Returns the current node document() Used to access the nodes in an external XML document element-available() Tests whether the element specified is supported by the XSLT processor format-number() Converts a number into a string function-available() Tests whether the function specified is supported by the XSLT processor generate-id() Returns a string value that uniquely identifies a specified node key() Returns a node-set using the index specified by an <xsl:key> element system-property() Returns the value of the system properties unparsed-entity-uri() Returns the URI of an unparsed entity   For more information –   http://www.w3schools.com/xsl/default.asp   Technorati Tags: Ritesh, Overview of XSLT

• Is there a way to return a response every x seconds or so to a single http request?

  - by luis

  I'm wondering if it's possible to send a response every second or so to a single http request. Like for example the client makes an http request, then the server sends a space character every second. This could be never ending or with a limit, for example a minute. I think the word 'response' is misleading in this context, since I don't necessarily mean an http response. The whole http response could be composed of the space characters, which would mean a single http response to a single http request, except that it is a minute long. I tried chunked encoding but I don't think it works, or at least my implementation's wrong.

• Microsoft Office sur iOS et Android : en 2013 ? Oui, non... peut-être

  Microsoft Office pour iPhone et Android Oui, non... peut-être Soyons prudent. Rien n'est encore très clair avec le « Buzz IT » du jour : Microsoft Office débarquerait sur iOS (iPhone, iPad, iPod) et Android dès 2013. L'information vient du site américain The Verge qui tiendrait lui-même le « scoop » de sources internes à Microsoft. D'après ses sources, rien de bien révolutionnaires cependant. Microsoft Office serait disponible sous la forme d'une application gratuite (histoire de ne pas financer des concurrents ?) qui ne permettra que la lecture des fichiers Word, PowerPoint, et Excel. Toujours d'après le site, l'édition des documents ne sera possible qu'avec un compte Offi...

• Ctrl-Alt-T doesn't open terminal

  - by user204591

  I'm using Ubuntu 13.10 and I've been using for a while now as ran it from a daily build about a month ago. It's fully updated with updates, upgrades an dist-upgrades and it was working up until very recently. Not sure exactly when I last issued a Ctrl+Alt+T as I quite often just leave it running however it will have been certainly in the last week. Basically when I hit that key combo I do not get a terminal. I know that each of the keys function as I can Atl+Tab through open applications and I can Ctrl+C to copy and past Ctrl+V to paste and I've typed plenty here that has a "T" in it. I have checked Keyboard Layout in Settings and the correct combo is assigned to the terminal. You'll have to take my word for that as I'm not allowed to post my screenshot!!!!!

• Are there Any Concerns with Importing Document Files From a Competing Product?

  - by Thunderforge

  I have a new product that serves the same purpose as my competitor's long-standing product. One thing I have considered doing is allowing my program to import document files created by their product in order to provide an easy way for users to migrate towards mine. Naturally, this would be done without the competitor's permission, as it goes against their interests. I've seen this done before with office suite software (e.g. Open Office and Apple Pages can import MS Word documents), but I'm wondering if there are any concerns, legal or ethical, with me doing this. I fully expect any answers will most likely fall under the "I am not a lawyer" clause, but it would be helpful to have a starting point for anything I would need to be aware of, or if I shouldn't need to worry.

• Improving FAQ SEO with multiple pages?

  - by asdfasdf

  I have a client who has over 200 Question/Answer style content blocks. Neither the questions or answers are very long and most of them have almost the same question but with a word or two differentiating themselves from the rest of the questions. Would SEO be helped or hurt if I would to put each QA on its own page with the title of the page the question being asked etc... Or, would that be considered "farming"? If not, what would be the best way (in SEO world) do present all these QAs? Thanks for any advice..

• category title and affect on SEO and ranking

  - by Mark

  We are working on a jobs and skills website (similiar to Skill Pages) and are deciding on categories. Rather than having load of categories like, for example, Builder, Electrician, Carpenter etc, we would like to have one word more general categories. So for example we have House, Computer, Education, Art etc. So a builder would be in category Home and a few others. Will this style negatively effect our SEO and ranking? And if so, should we abandon and go back to traditional categories and sub-categories?

• Possible to map mouse coordinates to isometric tiles with this coordinate system?

  - by plukich

  I'm trying to implement mouse interaction in a 2d isometric game, but I'm not sure if it's possible given the coordinate system used for tile maps in the game. I've read some helpful articles like this one: How to convert mouse coordinates to isometric indexes? However, this game's coordinate system is "jagged" for lack of a better word, and looks like this: Is it even possible to map mouse coordinates to this successfully, since the y-axis can't be drawn on this tile-map as a straight line? I've thought about doing odd-y-value translations and even-y-value translations with two different matricies, but that only makes sense going from tile-screen.

• Small Business Websites and the Internet High Street

  Most professionals, running their small businesses from high street premises, rightly expend huge amounts of time and effort on finding the right site to trade from; a wealth of consideration is given to every detail of the work place, from the colour of the carpets to the style of chair; professional designers are enlisted and marketing specialist consulted and a great deal of thought is given by all as to just how attractive the place will be to potential customers. With the beautiful new signs in place, all that's left to do is await passing trade, of course other marketing will be done and business also comes from word of mouth, but it is this visual presence on the high street that is all important to such firms.

• Dynamic Strategy Pattern [migrated]

  - by Karl Barker

  So I'm writing a web service architecture which includes FunctionProvider classes which do the actual processing of requests, and a main Endpoint class which receives and delegates requests to the proper FunctionProvider. I don't know exactly the FunctionProviders available at runtime, so I need to be able to 'register' (if that's the right word) them with my main Endpoint class, and query them to see if they match an incoming request. public class MyFunc implements FunctionProvider{ static { MyEndpoint.register(MyFunc); } public Boolean matchesRequest(Request req){...} public void processRequest(Request req){...} } public class MyEndpoint{ private static ArrayList<FunctionProvider> functions = new ArrayList<FunctionProvider>(); public void register(Class clz){ functions.add(clz); } public void doPost(Request request){ //find the FunctionProvider in functions //matching the request } } I've really not done much reflective Java like this (and the above is likely wrong, but hopefully demonstrates my intentions). What's the nicest way to implement this without getting hacky?

• Azure, a Beautiful Color, and So Much More...

  - by KKline

  Windows and SQL Azure Resources Cloud computing is more than just the latest buzz word in the IT trade papers. It is a remarkable paradigm shift with as much potential to "turn over the apple cart" of IT computing as client-server had for the world of mainframe and minicomputers. If you're not spending time to learn about cloud computing, in general, and SQL Azure, in particular, then you're missing the boat in a big way. (Ha! Two big metaphors in one afternoon.

• How can I ensure reasonably spaced out enemies

  - by Samuraisoulification

  I have a simple javascript game and I'm initializing their positions on the y axis using random numbers. How can I ensure that they are reasonably spaced apart? My simple algorithm is: y = (Math.random()*1000%600); However I frequently get enemies almost directly on top of each other. This is a huge problem for the game, since it's a word game and the enemies have text on their center, that if overlapped makes them impossible to kill since you can't see the words. Any advice would be appreciated! I'm pretty new to making games in general so this has all been a learning experience for me!

• Synchronizing Mysql Table Schema [on hold]

  - by user1122069

  I have some difficulty keeping track of my SQL changes in a text file in SVN. One solution that I am aware of is to put the SQL queries in files (1.sql, 2.sql...) and to manually load each file at the proper time. Besides missing commas, the process is too cumbersome when builds become more frequent. I have actually taken to asking a co-worker to send me his SQL changes on Skype and we just apply the changes immediately on our local, development, and production servers (using three PhpMyAdmin tabs). I have seen several GUI tools mentioned in similar questions on SO, but these are actually more work and less automated than the aforementioned methods. Is there any standardized process by which this is done in an automated way? I can only guess that large companies build their own mechanisms of keeping track of database schema changes (yet I can't find a word about it - maybe they use files?). This question was closed as off-topic on Stack Overflow, so I am re-posting it here.

• Using replacement to get possible outcomes to then search through HUGE amount of data

  - by Samuel Cambridge

  I have a database table holding 40 million records (table A). Each record has a string a user can search for. I also have a table with a list of character replacements (table B) i.e. i = Y, I = 1 etc. I need to be able to take the string a user is searching for, iterate through each letter and create an array of every possible outcome (the users string, then each outcome with alternative letters used). I need to check for alternatives on both lower and uppercase letters in the word A search string can be no longer than 10 characters long. I'm using PHP and a MySQL database. Does anyone have any thoughts / articles / guidance on doing this in an efficient way?

• Need suggestions on what you regard as &ldquo;security&rdquo;

  I’m currently writing a large piece on MSMQ security and wanted to check I was covering the right areas. I have some doubts as I’ve seen the occasional MSMQ forum question where a poster has used the word “security” in different contexts to what I was expecting. So here are the areas I plan to cover: Message security encryption on the wire (SSL and IPSEC) encryption of the message (MSMQ encryption) encryption of the payload (data encryption) signing and authentication Queue security SIDs and ACLs Discoverability Cross-forest issues Storage security NTFS permissions unencrypted data Service security Ports and Firewalls DOS attacks Hardened mode (HTTP only) RPC secure channel requirement authenticated RPC requirement Active Directory object permissions Setup Administrator requirements What else would you want to see?

• How to show history of edits for a post like StackExchange? [on hold]

  - by volume one

  Using: ColdFusion 10, JQuery, IIS 7.5 I'm creating a system where people can submit their text articles to me and I can apply edits/corrections and send it back to them. However I don't want to lose their original work. I want them to see where I made edits. StackExchange pretty much does what I want by showing when a post was edited and then you can see the history of changes. Can anyone please suggest how to go about doing this? Everytime an edit is made, it has to be written to the database. But how do I show what was edited? It could be 1 word in a whole paragraph... how would I highlight this? I just need some pointers if possible at what to think about and what to use if anyone has the time to help me out.
