  • Is there any free live support solution that would ease implementation of a basic online help-desk?

    - by bogdan
    I'm looking for a free or inexpensive solution to give live online support to web visitors. I would like something based on Jabber/XMPP because it's an open protocol. This should work like this: The company would use 2-3 jabber accounts like Google Talk for providing support Online chat form that would connect to one of currently online jabber accounts Optionally give one proxy jabber account to the customers. This proxy would contact any of the currently online company accounts. Using this customers will see only one chat contact but they will speak with different people based on who is online at the moment. Currently I found only some expensive solutions like J-livesupport, Akeni. I would really appreciate if you will recommend something you successfully implemented.

  • Computer Vision Website Image Slideshow help

    - by msandbot
    Hi, I'm making an online display of the output of a computer vision algorithm. After running the algorithm I am left with a folder of about 1000 16 bit .tiff files. I need to put those on the website in a list for so that the researchers can click through and find the list. Also there needs to be an image frame with an "animated gif" feel that can be started stopped and played in reverse. Any ideas on the best way to do this? What language to use? I made a simple website in Ruby on Rails but I don't know if it has the capabilities to do what I require.

  • Using Google to find programming answers (does locale matter)?

    - by Jason
    I have overseas developers working for me, and sometimes I am surprised they can't find the same resources online that I do. They are in a South America country... and Google defaults to their language/locale. What do you think about this, when using it to solve computer programs? There is very little software development done in their country (as compared to the US). Is Google skewing their results for articles in their language or posted on sites that are local to them? Should I insist that they bypass their local Google search and have them use the US version?

    Was ist ADF? ADF steht für Oracle Application Develoment Framework. ADF setzt die JEE Standards um und erweitert deren Funktionalität insbesondere im Hinblick auf die Vielzahl der zur Verfügung gestellten Komponenten (insbesondere im Hinblick auf die Visualisierung) und im Bereich der Ablaufsteuerung (Taskflows ersetzen Pageflows). ADF ist einer der Bausteine, auf denen die Entwicklung aller neuen Oracle Anwendungssysteme beruht (inkl. Vertical Solutions und der Administrationswerkzeuge). Das verwendete Entwicklungswerkzeug ist der Oracle JDeveloper. Rapid Application Development (RAD) wird durch eine deklarative, Metadaten getriebene Entwicklung ermöglicht, die auf allen Ebenen in starkem Maße mit Templating (also der Möglichkeit, mit vorgegebenen Mustern zu arbeiten) und mit Wiederverwendbarkeit arbeitet. Entwicklung und Dokumentation erfolgen in einem Schritt. ADF arbeitet nahtlos mit den anderen Oracle SOA Werkzeugen zusammen und bringt ein Rollen-/ Policy getriebenes Zugriffssystem mit. Es ist in das Oracle Identity Management integrierbar. ADF News Online Sessions? Die ADF News Online Sessions geben Tipps von Anwendern/Entscheidern für Anwender/Entscheider und bieten einen Ideenaustausch für den Einsatz von ADF bzw. für die Umsetzung von ADF Projekten.

  • What are the advantages and disadvantages to using your real name online?

    - by Jon Purdy
    As a programmer, do you see any professional or other advantage in using your real name in online discourse, versus an invented handle? I've always gone by a single username and had my real name displayed whenever possible, for a few reasons: My interests online are almost exclusively professional and aboveboard. It constructs a search-friendly public log of all of my work, everywhere. If someone wants to contact me, there are many ways to do it. My portfolio of work is all tied to me personally. Possible cons to full disclosure include: If you feel like becoming involved in something untoward, it could be harder. The psychopath who inherits your project can more easily find out where you live. You might be spammed by people who are not worth the precious time that could be better spent writing more of the brilliant software you're famous for. Your portfolio of work is all tied to you personally. It seems, anyway, that a vast majority of StackOverflow users go by invented handles rather than real names. Notable exceptions include the best-known users, who are typically well established in the industry. But how could we ever become legendary rockstar programmers if we didn't get our names out there? Discuss.

  • How to develop Online Shopping Portal Application using PHP ?

    - by Sarang
    I do not know PHP & I have to develop a Shopping Portal with following Definition : Scenario: Online Shopping Portal XYZ.com wants to create an online shopping portal for managing its registered customers and their shopping. The customers need to register themselves first before they do shopping using the shopping portal. However, everyone, whether registered or not, can view the various products along with the prices listed in the portal. The registered customers, after logging in, are allowed to place order for one or more products from the products listed in the portal. Once the order is placed, the customer gets a reference order number and the order status should be “order in process”. The customers can track their order using the given reference number. The management of XYZ.com should be able to modify the order status of a particular reference order number to “shipped” once the products are shipped to the shipping address entered by the customer at the time of placing the order. The Functionalities required are : Create the interface for the XYZ.com shopping portal using HTML/XHTML and CSS. Implement the client side validations using JavaScript. Create the tables using MySQL. Implement the functionality using the server side scripting language, PHP. Integrate all the above tasks and make the XYZ.com shopping portal functional. How do I develop this application with following proper steps of development ?

  • How can I build something like Amazon S3 in Perl?

    - by Joel G
    I am looking to code a file storage application in perl similar to amazon s3. I already have a amazon s3 clone that I found online called parkplace but its in ruby and is old also isn't built for high loads. I am not really sure what modules and programs I should use so id like some help picking them out. My requirements are listed below (yes I know there are lots but I could start simple then add more once I get it going): Easy API implementation for client side apps. (maybe REST (?) Centralized database server for the USERDB (maybe PostgreSQL (?). Logging of all connections, bandwidth used, well pretty much everything to a centralized server (maybe PostgreSQL again (?). Easy server side configuration (config file(s) stored on the servers). Web based control panel for admin(s) and user(s) to show logs. (could work just running queries from the databases) Fast High Uptime Low memory usage Some sort of load distribution/load balancer (maybe a dns based or pound or perlbal or something else (?). Maybe a cache of some sort (memcached or parlbal or something else (?). Thanks in advance

  • Database design for credit based purchases

    - by FreshCode
    I need an elegant way to implement credit-based purchases for an online store with a small variety of products which can be purchased using virtual credit or real currency. Alternatively, products could only be priced in credits. Previous work I have implemented credit-based purchasing before using different product types (eg. Credit, Voucher or Music) with post-order processing to assign purchased credit to users in the form of real currency, which could subsequently be used to discount future orders' charge totals. This worked fairly well as a makeshift solution, but did not succeed in disconnecting the virtual currency from the real currency, which is what I'd like to do, since spending credits is psychologically easier for customers than spending real currency. Design I need guidance on designing the database correctly with support for the simultaneous bulk purchase of credits at a discount along with real currency products. Alternatively, should all products be priced in credits and only credit have a real currency value? Existing Database Design Partial Products table: ProductId Title Type UnitPrice SalePrice Partial Orders table: OrderId UserId (related to Users table, not shown) Status Value Total Partial OrderItems table (similar to CartItems table): OrderItemId OrderId (related to Orders table) ProductId (related to Products table) Quantity UnitPrice SalePrice Prospective UserCredits table: CreditId UserId (related to Users table, not shown) Value (+/- value. Summed over time to determine saldo.) Date I'm using ASP.NET MVC and LINQ-to-SQL on a SQL Server database.

  • Need a design pattern for representing multiple information sources

    - by hsmit
    I'm building a Java application that retrieves information from differing information sources. I'm using a sensor, a set of RecordStores and a few online web services. In the basic application all these resources are loaded by default. Some of these sources are directly read in a separate thread (load database, read sensor etc.). From this basic application some functions are started that use these sources. The classes that contain these functions (usually combining multiple sources information) are currently paramterized with a set of resources like this: AppPart a1 = new AppPart(source1, source2, source3); I could also do it like this AppPart a1 = new AppPart(this); ..where I need to make my sources public in order to read them. I'm also thinking about a kind of stage/collection to publish all sources on, e.g: public SourceCollectionStage sStage = new SourceCollectionStage(); and later: sStage.getSensor(); .. for example. What do you guys think is the best or most often used way to do this? Btw: the user interface is often implemented by the specific funtion classes, not by the main class. Should I do this in another way?

  • Why are (almost) all the on-line games written in ActionScript (Flash) not Java?

    - by MasterPeter
    I absolutely love good defender games (e.g. Gemcraft, Protector: reclaiming the throne) as they can be intellectually quite challenging; it's like playing chess but a little less thinking a bit more action. Sadly, there are not that many good ones out there and I thought I would create one myself and share it with the rest of the world by making it available on-line. I have never worked with ActionScript but when it comes to on-line games, this is the main choice. I have tried to find a decent 2D game in the form of a Java applet but to no avail. Why is this so? I could write the game, most comfortably, in Delphi for Win32 but then people would need to download the executable, which could deter some form downloading it, and also it would only work on Windows. I am also familiar with Java, having worked with Java for the last four years or so. Although I don't have much experience with games programming. Should I note be deterred by the fact that all online games are written for in Flash and create my defender game as a Java applet, or should I consider learning ActionScript and games development for the ActionScript Virtual Machine (AS3 looks very much like Java... but still, it's an entirely new technology to me and I might never use it professionally.) Could you, please, just answer the the question in the title? Why Flash, not Java applets? Is it only 'politics'?

  • Bargain Hunter Round Up – Kicking Off The E-Commerce Holiday Season

    - by Jeri Kelley
    Everyone has a different way to tackle holiday shopping – Black Friday, Small Business Saturday, Cyber Monday, some have it done months in advance, and others wait until the very last minute.   For me, I’m not big into massive crowds so online shopping to the rescue.   Others thrive on the energy of being in the stores on the busiest shopping day of the year.  With last weekend marking the official kick-off to the holiday season, I thought I’d provide a round up of what’s trending:   Online numbers are looking up: According to comScore, for the holiday season-to-date, $16.4 billion has been spent online, marking a 16-percent increase versus the corresponding days last year. Thanksgiving Day – Why wait until Black Friday or Cyber Monday: Online shopping on Thanksgiving Day also increased, totaling $633 million in receipts, a 32 percent increase over Thanksgiving 2011 Black Friday – More than just in-store: Bargain hunters spent $1.042 billion online the day after Thanksgiving, a 26 percent increase of last year's Black Friday, according to new figures released today by market analyst ComScore Cyber Monday Week: Cyber Monday reached $1.465 billion in online spending, up 17 percent versus year ago, representing the heaviest online spending day in history and the second day this season (in addition to Black Friday) to surpass $1 billion in sales                 Cyber Monday is now being dubbed Cyber Week:  “The annual event is increasingly becoming Cyber Week instead of a one-day event as retailers open their arms for Americans who prefer to avoid crowds and compare prices online.” But, Cyber Monday continues its importance, driving a nearly 22% increase in year-over-year (YoY) online sales. Monday sales beat Sunday, the next highest day by a margin of 26.7%. Mobile shopping continues to rise: ChannelAdvisor that said mobile shopping made up 32% of all online spending over the Black Friday weekend Mobile devices were a key part of the online shopping craziness that was November 26th.  Sales from smartphones and tablets doubled this year. I n tablets the growth was 110% and in smartphones - 100% Mobile bar code scans on Black Friday increased 50 percent, according to a report from ScanLife For more on how you can be ready for the holiday season, check out my blog post on commerce strategies for the holidays.

  • Will the Rosetta Stone online edition work with Ubuntu?

  • Does something like this "dream" online IDE product exist?

    - by Dan Tao
    I was thinking the other day, it would be amazing if a web-based product with the following features existed: Customizable text editor with nice formatting like ACE Real-time collaborative editing like Google Docs (or the late Wave) Online multi-language compiling capabilities like Ideone.com SCM hosting and/or integration + issue management like... oh, I don't know, GitHub Clearly (considering the examples), all the desired features exist. Is there anywhere that they exist all in one product? If not, does anything come close?

  • Fix Online Management - Which SEO Mistakes Should Be Eliminated?

    In search engines, websites are very keenly observed before being ranked and it is very obvious if we end up making certain small mistakes. However, nobody is aware about the fact that these small mistakes can cause serious blunders to their websites. The most important requirement for developers is that they should recognize their mistakes, correct them as soon as possible using good online reputation management skills and remove Google results that act against them.

  • is there some lightweight tecnique for adding type safety to identifier properties?

    - by shoren
    After using C++ I got used to the concept of Identifier which can be used with a class for the type, provides type safety and has no runtime overhead (the actual size is the size of the primitive). I want to do something like that, so I will not make mistakes like: personDao.find(book.getId());//I want compilation to fail personDao.find(book.getOwnerId());//I want compilation to succeed Possible solutuions that I don't like: For every entity have an entity id class wrapping the id primitive. I don't like the code bloat. Create a generic Identifier class. Code like this will not compile: void foo(Identifier book); void foo(Identifier person); Does anyone know of a better way? Is there a library with a utility such as this? Is implementing this an overkill? And the best of all, can this be done in Java without the object overhead like in C++?
