  • Writing a spell checker similar to "did you mean"

    - by user888734
    I'm hoping to write a spellchecker for search queries in a web application - not unlike Google's "Did you mean?" The algorithm will be loosely based on this: http://catalog.ldc.upenn.edu/LDC2006T13 In short, it generates correction candidates and scores them on how often they appear (along with adjacent words in the search query) in an enormous dataset of known n-grams - Google Web 1T - which contains well over 1 billion 5-grams. I'm not using the Web 1T dataset, but building my n-gram sets from my own documents - about 200k docs, and I'm estimating tens or hundreds of millions of n-grams will be generated. This kind of process is pushing the limits of my understanding of basic computing performance - can I simply load my n-grams into memory in a hashtable or dictionary when the app starts? Is the only limiting factor the amount of memory on the machine? Or am I barking up the wrong tree? Perhaps putting all my n-grams in a graph database with some sort of tree query optimisation? Could that ever be fast enough?

  • Best Practice to return responses from service

    - by A9S6
    I am writing a SOAP based ASP.NET Web Service having a number of methods to deal with Client objects. e.g: int AddClient(Client c) = returns Client ID when successful List GetClients() Client GetClientInfo(int clientId) In the above methods, the return value/object for each method corresponds to the "all good" scenario i.e. A client Id will be returned if AddClient was successful or a List< of Client objects will be returned by GetClients. But what if an error occurs, how do I convey the error message to the caller? I was thinking of having a Response class: Response { StatusCode, StatusMessage, Details } where Details will hold the actual response but in that case the caller will have to cast the response every time. What are your views on the above? Is there a better solution? ---------- UPDATED ----------- Is there something new in WCF for the above? What difference will it make If I change the ASP.NET Web Service to a WCF Service?

  • Is JScript dying? If so, where should I go? [closed]

    - by David Is Not Here
    I recently poked around Google for a little bit, looking for information about coding JScript. It's very sparse, which surprised me -- it took a link to a link to find Microsoft's own reference, which appears to omit most if not all references to console-based scripting that extends past Javascript. I'm working with the console here, not a webpage, so input and output seems very different than what Microsoft explains. If JScript is dying (and it appears to be so), where do I go from here? VBScript? My options are limited because the computers I'm using this on are carefully patrolled for new software. JScript's similarity to JavaScript was the biggest reason I had chosen it for porting over some of my prior work. I'm specifically looking for, at best, a console scripting language that doesn't need any extra software on Windows XP or higher, that at least supports standard input, output, pause, and file manipulation, little else.

  • Lumia 920 or iPhone5, which is it gonna be?

    - by Sahil Malik
    SharePoint 2010 Training: more information Deciding on a new phone is so difficult. I currently use an iPhone4, and I am itching to upgrade to either iPhone5 or Lumia 920. The decision is difficult because a lot of my work depends on my communication device, and whatever I pick, I will be stuck with for 2 years. Here is how I see the two stacking up. iPhone 5 of course based on rumors so far. I didn’t even consider Android here because I don’t like Android as an OS. It’s too insecure, privacy intrusive, and frankly unreliable. I cannot bet my work on Android, sorry not gonna happen. Read full article ....

  • Installer doesn't recognise windows 7 install

    - by SirWaffleRaptor
    I will start off saying I searched a bit for this problem with little success. You see, I am an utmost noob when it comes to Ubuntu and Linux based OS (hence why I want to install it and discover it) and the thread I found were too specific for me to do anything with. Therefore, if you find a thread that is noob-friendly and answers my question, please link it below or please try to answer as simply as possible :) The problem: I want to install Ubuntu 12.04 LTS 64 bit alongside Windows 7 on my main hard drive (to get the choice which one to start when booting). Pop the CD in, reboot and get to the installer screen. I know I'm supposed to have 3 options, but I'm only given the option to erase my hard drive or "do something else". Therefore, my question is: how do I make Ubuntu recognise Windows 7, so it may install alongside it?

  • Why can't I mount the Ubuntu 12.04 installer ISOs in Mac OS X?

    - by eric
    Over the past few days, I have downloaded both the 32 and 64 bit version of server and desktop to install on an Intel based PC. It is normal from within OS X to double click on an ISO and it will mount the ISO in the finder as well as within disk utility. When I attempt to mount any of the Ubuntu ISOs I downloaded, OS X returns the error message The following disk images couldn't be opened. The reason given for the error is no mountable filesystem. However, I am still able to open the ISO directly from disk utility and burn it to a DVD/CD. What has changed in this release to cause this? Is there something wrong with the current ISOs? The OS X machine I am using is only two weeks old and is having no issues with any other ISO.

  • Is there any Ubuntu translation indicator?

    - by Oyibo
    For more precision: I'm runnning Ubuntu 12.04 I'd like an indicator which shows up to the left of the date/volume/wifi icons If possible I'd like to be able to change the translation language The indicator could use internet based translators (google translate etc.) or have a complete library come with it so translations can be obtained offline. Relating to usability: I'd like to have it work in a way where you click on the indicator icon and you can start typing either directly or once a window has opened and it instantly shows the translation you need (with your target languages pre-set or determined in options).

  • Wrong download of Ubuntu 13.10 desktop: AMD instead of wanted Intel [duplicate]

    - by L. Williams
    This question already has an answer here: Difference between the i386 download and the amd64? 5 answers My PCs are Intel CPUs e.g. Core2 Quad, 64 bit, no AMD in network, but from ubuntu.com/download site, selecting 13.10 Desktop for 64 bit, it repeatedly only offers *AMD.ISO version, which of course fails to install on my Intel (or Atom) based PCs. Wuzzup, and what URL has a download for the Intel CPU systems? Rem: this is for Saucy 13.10 Desktop 64 OS ISO. TIA.

  • Is there an OSS license that works for this:

    - by mattcodes
    Say you started as SaaS service with freemium business model such 37Signals - Basecamp or Dropbox etc.. Is there an OSS license that says that you can use the source code etc.. but you cant release a SaaS based on it, esssentially released in good faith with non-compete expectations. e.g. if 37Signals released the source for highrise, basecamp etc.. someone could start 37signals4lesss.com (albeit once they built the same bit of provisioning logic) and damage the core business model.

  • Communication between Box2D and libGDX Stage (Scene2D) running in separate threads

    - by atok
    I'm making a physics based 2D game using libGDX and Box2D. I want to move the execution of the simulation out of render thread. I use immutable messages and the BlockingQueue to pass the information about player actions. The Box2D applies forces and runs a frame of simulation. In the next step I would like to sync back the changes and update Scene2D Actors accordingly. Making an immutable copy of the state of the game world and sending it back using Gdx.app.postRunnable() is one option but it seems inefficient. Is there any other option?

  • Is using build-in sorting considered cheating in practice tests?

    - by user10326
    I am using one of the practice online judges where a practice problem is asked and one submits the answer and gets back if it is accepted or not based on test inputs. My question is the following: In one of the practice tests, I needed to sort an array as part of the solution algorithm. If it matters the problem was: find 2 numbers in an array that add up to a specific target. As part of my algorithm I sorted the array, but to do that I used Java's quicksort and not implement sorting as part of the same method. To do that I had to do: java.util.Arrays.sort(array); Since I had to use the fully qualified name I am wondering if this is a kind of "cheating". (I mean perhaps an online judge does not expect this) Is it? In a formal interview (since these tests are practice for interview as I understand) would this be acceptable?

  • Making sub domain the new main domains for ssl

    - by Dean Legg
    What would be your best advise for changing your main domain to a sub domain? Are site used to be example.co.uk but has now changed to https://secure.example.co.uk/. Any example.co.uk url's re-direct to the new secure domain. Effectively the example.co.uk is now just there to redirect any links and is no longer part of the sites url structure. I have added a new domain to Google Webmaster https://secure.example.co.uk/ and added the site map. Waiting for it to be indexed. Is there anything else you would advise and will this take away a lot of the juice from all the links I developed for example.co.uk? Guessing this is not best practise as I have struggled to find any information online based on this subject.

  • ssh Password-less login to multiple machines when you already have one

    - by tandu
    I'm a little bit confused about setting up a password-less login for multiple machines to begin with, but I think I could do it from scratch. The problem is I already have it set up for one machine and I don't want that to be blown away when I try to set it up for the other machine. Let's clarify: Machine A: the machine I'm connecting from Machine B: the machine I'm connecting to. Password required Machine C: the machine I'm connecting to. Password-less ssh I have read some tutorials on setting up password-less ssh to a certain site, but they usually start with "move id_rsa out of the way so it doesn't get blown away," but then at the end of the tutorial it's not moved back. If I had no help at all, here is what I would do: Log into B ssh-keygen -t rsa -f ~/id_rsa.other scp id_rsa.other.pub A:~/.ssh echo "Host A \n Identity File ~/.ssh/id_rsa.other" > ~/.ssh/config (Note that I realize these commands may not be exactly correct, but this is just the idea). What I'm not quite clear on is if I need to update the config for A, B, or both. I'm fairly certain to do a password-less login from A to B, it is A that needs the public key .. but I also suppose I need B to use the correct id_rsa file for that public key. Finally, I don't want the password-less login for C to be affected at all .. it's using id_rsa. Am I going wrong anywhere?

  • Django - need to split a table across multiple locations [closed]

    - by MikeRand
    Hi all, I have a Django project to track our company's restructuring projects. Here's the very simple model: class Project(models.Model): code = models.CharField(max_length=30) description = models.CharField(max_length=60) class Employee(models.Model): project = models.ForeignKey(Project) employee_id = models.IntegerField() country_code = models.CharField(max_length=3) severance = models.IntegerField() Due to regulations in some European countries, I'm not allowed to keep employee-level severance information in a database that sits on a box outside of that country. In Django, how do I manage the need to have my Employee table split across multiple databases based on an Employee attribute (i.e. country_code) in a way that doesn't impact anything else in the project (e.g. views, templates, admin)? Thanks, Mike

  • How to detect and collide two elastic line segments?

    - by Tautrimas
    There are 4 moving physical nodes in 3D space. They are paired with two elastic line segments / strings (1 <- 2; 3 <- 4). Part I: How to detect the collision of two segments? Part II: On the moment of collision, fifth node is created at the intersection point and here you have the force-based graph. 5-th node (bend point) can slide among the strings as in a real world. Given the new coordinates of 4 nodes, how to calculate the position of the 5-th node on the next frame? I assume string force on the nodes to be F = -k * x where x is the string length. All I came up to is that the force between 5 and 1 equals 5 and 2 (the same with 3 and 4). What are the other properties?.

  • Change from static HTML file to meta tag for Google Webmaster verification

    - by Wilfred Springer
    I started verifying the server by putting a couple of static HTMLs in place. Then I noticed that Google wants you to keep these files in place. I didn't want to keep the static HTMLs in, so I want to switch to an alternative verification mechanism, and include the meta tags on the home page. Unfortunately, once your site is verified, you never seem to be able to change to an alternative way of verification. I tried removing the HTML pages. No luck whatsoever. Google still considers the site to be 'verified'. Does anybody know how to undo this? All I want to do is switch to the meta tag based method of site ownership verification.

  • R12.0 Cash Management Consolidated Patch Collection (CPC) And R12.1 Cash Management Recommended Patch Collection (RPC)

    - by user793553
    If you have Oracle E-Business Suite's Cash Management (CE) application installed, you'll want to be sure to install the latest CPC (Consolidated Patch Collection) if you are using a R12.0 version of the apps, or the latest RPC (Recommended Patch Collection) for the R12.1 version of the apps. These collections give you all the fixes currently available for known issues in the specified versions of the application, including all of the latest Root Cause Analysis Fixes (RCAs)! What is an "RPC" (for R12.1 users)? Since the release of 12.1, a number of recommended patches for Oracle Cash Management have been made available as standalone patches to help address important business process issues. Adoption of these patches was highly recommended at the time, but not always implemented, so to further facilitate adoption of these patches, Oracle consolidated them into product-specific Recommended Patch Collections (RPCs) - a collection of recommended patches. They were created by Oracle Development with the following goals in mind: Stability: To address data integrity issues that have been identified by Oracle Development and Oracle Software Support as having the potential to interfere with the normal completion of important business processes (such as, period close, etc.). Root Cause Fixes (RCAs): To make available root cause fixes for known data integrity issues. Compact: To keep the file footprint as small as possible to help facilitate the install process and minimize testing. Granular: To compile the collection of patches based on functional areas, allowing a customer to apply multiple RPCs at once, or in phases (based on individual needs and goals). Where to start ALL R12 Cash Management users (R12.0 and R12.1 users) should start with the following Note on My Oracle Support (MOS): Doc ID 1367845.1: R12: Cash Management Recommended Patch Collections It's a great place for important implementation information about both sets of critical patch collections! For R12.1x users R12.1 users should also take a look at the documents below for even more information about the RPC for the R12.1.x versions of the Cash Management application, and other related available RPCs: Note Number  Title                                                                                                      1489997.1 Master Troubleshooting Guide for CE: Reconciliation & Clearing [VIDEO] 954704.1 EBS: R12.1 Oracle Financials Recommended Patch Collections (RPCs) 1316506.1 R12: Oracle CE: Upgrading from R11i to R12.1: Latest Recommended Patches Patch Wizard Utility While a patch may contain several hundred files, the impact on your system may actually be minimal. Patches contain hard prerequisites that are intended to make a patch work on a very low code baseline. The Patch Wizard Utility will give you a detailed analysis of the patch’s impact on your instance BEFORE it’s applied, so you’ll know exactly what to expect from the application. Please refer to Doc ID 976188.1 for more information on this important utility

  • Handle php out of memory error

    - by PeterMmm
    I have a Drupal based web site on a relative small vserver (512MB RAM). Recently the website begins to return php out of memory messages like this: Fatal error: Out of memory (allocated 17039360) (tried to allocate 77824 bytes) in /home/... All php.ini memory limit parameters are set to off (-1). Propably the website has gained of complexity, content, etc. But I cannot interpret fine that message: Does that mean that the whole request has allocated 17MB(?) right now and cannot get 7MB(?) more from the OS. Has the web server spend all memory or has the OS no more memory to allocate ? I'm not shure if the memory overhead is coming from the web server or another service, because when I get the out-of-memoy message I can't get into the server with ssh. After a while all runs fine again.

  • Custom vs. browser-native scrollbars

    - by vemv
    Including customizable, JavaScript-based scrollbars (and scrolling functionality in general, i.e. bind the control to the mouse scroll wheel) in your webapp can be a great temptation. However all solutions I could find were developed by individuals (which can equal lack of formal or future support). In addition I fail to remember any mainstream site using them. In my particular case, no-JavaScript or IE6/odd-browser environments are not intended to be supported. Should custom scrollbars be avoided nowadays? If not, what's the best option one can choose?

  • How to install Ubuntu One server software or alternative for personal use?

    I have a Debian based box in my house that runs as a webserver, and a 4GB bootable usb-stick with Ubuntu. I need to store stuff on a server and Ubuntu One seems an ok way to go but I find that 2GB is not sufficient. I can most likely solve that when I install this server software. Where can I find it - there is no ubuntu-one-server package or similar in the Software Centre. How can I install the Ubuntu One server software or an alternative?
