• Bug fix for Eclipse runtime plugin

  - by Peter Benedikovic

  This blog is intended to inform about bug fix that solves this issue. Before continuing further, one important note – the linux and mac users do not need to read further because this bug appears only on Windows.  The problem was that the runtime plugin registered new runtime and server each time the Eclipse started. Users ended up with server view looking like this: I have created new runtime plugin which is now available at the update site http://download.java.net/glassfish/eclipse/indigo (or the same ending with juno for Juno users). You will still need to unistall the buggy plugin and (optionally but recommended) to remove runtimes created by this plugin. Here is the guide how to install bugfix: Uninstall buggy runtime plugin via menu Help->About Eclipse->Installation details. Remove runtimes created by old plugin – via Window->Preferences->Server->Runtime Environment. After pressing remove button you may be asked if you want to remove also the servers based on runtime being removed. Recommended is to do so. Now you can install new runtime plugin. Go to Help->Install New Software. You may ask why I haven‘t provided the update for buggy runtime which could be installed via Check for updates feature of Eclipse. It has two main reasons: The bug fix is needed only for Windows users so I didn't want to bother other users by updating working plugin. The runtime plugin has had structure that was not quite suitable for Eclipse update. This structure is now changed so future bugs (I am sure that there will be no such ;)) can be fixed by standard update. Have a good one!

• Concatenate cells that change daily automatically?

  - by Harold

  I use concatenate to pull data together from different cells in my spreadsheet. Since my data changes daily, I want the formula to also change daily without having to manually input the new cell in the concatenate formula. I am looking for a way to do this but not sure how. Can anyone out there help me out please!? I appreciate the assistance in advance! Maybe this will help to explain what I need. I have a row of data from D4:AH4 that I insert daily based on the new day. When I use the concatenate and us the following formula: =CONCATENATE(TEXT('Raw Data'!B4,"m/d")," ",TEXT('Raw Data'!C4,"")," ", TEXT('Raw Data'!E4,"0.0%"))... E4 being the cell that changes daily where next day would be F4, G4, etc... All other parts of the formula will stay the same. I hope this helps! Thanks! :)

• Most efficient Way to setup a game server

  - by alex bowers

  I'm running a PHP based game which has over 45 Million members predicted for end of this year (2011) Currently we are on 7.5 Million, this game is being ran on facebook and I am in desperate need to help get this game server as efficient and as powerful as possible. it is a dedicated server with Processor Manufacturer Intel Model i7 920 Frequency 4x 2x 2.66 GHz NIC GigaEthernet RAM 12 GB Hard disk 4 x 1 TB specs. It has apache installed, cPanel, phpMyAdmin, several apache mods and MySQL. The game also runs 47 mysql calls per second per user. Is there any alternatives to the above which could be faster, more efficient etc? I dont mind having to recode the game to fit to it, as long as it maximises our upper limit of members on the game. Thanks Also, is there a way to tell what our maximum limit to players, database calls etc is? Thank you again, hope you guys can help :)

• What's the ethos of the programming profession?

  - by mac

  I am one of those people who became professional programmer by chance, rather than by choice: I moved to a country whose main language I couldn't speak, I knew how to code... and here I am a few years later. Because of this I never really gave much a thought about the ethos of being a programmer, and working as a freelance I neither had many occasions to discuss this with fellow colleagues. Among others, Dictionary.com define the word ethos as follows: The fundamental character or spirit of a culture; the underlying sentiment that informs the beliefs, customs, or practices of a group or society; dominant assumptions of a people or period. So my question is: How would you describe the ethos of being a programmer, and why would you say so? Please note that: my question is different than this and this other ones (although you might have chosen to become a programmer because of the programmer'ethos or you might think that part of the programmer ethos is about "programming being a meaningful profession"). beside the "how/what" part of the question, there is a "why" part too! :) I would appreciate if the answer could be based not only on the idealised vision of the hero-programmer, but also on real working and life experience. Thank you in advance for your time and contributions!

• Self-referencing anonymous closures: is JavaScript incomplete?

  - by Tom Auger

  Does the fact that anonymous self-referencing function closures are so prevelant in JavaScript suggest that JavaScript is an incomplete specification? We see so much of this: (function () { /* do cool stuff */ })(); and I suppose everything is a matter of taste, but does this not look like a kludge, when all you want is a private namespace? Couldn't JavaScript implement packages and proper classes? Compare to ActionScript 3, also based on EMACScript, where you get package com.tomauger { import bar; class Foo { public function Foo(){ // etc... } public function show(){ // show stuff } public function hide(){ // hide stuff } // etc... } } Contrast to the convolutions we perform in JavaScript (this, from the jQuery plugin authoring documentation): (function( $ ){ var methods = { init : function( options ) { // THIS }, show : function( ) { // IS }, hide : function( ) { // GOOD }, update : function( content ) { // !!! } }; $.fn.tooltip = function( method ) { // Method calling logic if ( methods[method] ) { return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 )); } else if ( typeof method === 'object' || ! method ) { return methods.init.apply( this, arguments ); } else { $.error( 'Method ' + method + ' does not exist on jQuery.tooltip' ); } }; })( jQuery ); I appreciate that this question could easily degenerate into a rant about preferences and programming styles, but I'm actually very curious to hear how you seasoned programmers feel about this and whether it feels natural, like learning different idiosyncrasies of a new language, or kludgy, like a workaround to some basic programming language components that are just not implemented?

• IT Optimization Plan Pays Off For UK Retailer

  - by [email protected]

  I caught this article in ComputerworldUK yesterday. The headline talks about UK-based supermarket chain Morrisons is increasing their IT spend...OK, sounds good. Even nicer that Oracle is a big part of that. But what caught my eye were three things: 1) Morrison's truly has a long term strategy for IT. In this case, modernizing and optimizing how they use IT for business advantage. 2) Even in a tough economic climate, Morrison's views IT investments as contributing to and improving the bottom line. Specifically, "The investment in IT contributed to a 21 percent increase in Morrison's underlying profit.." 3) The phased, 3-year "Optimization Plan" took a holistic approach to their business--from CRM and Supply Chain systems to the underlying application infrastructure. On the infrastructure front, adopting a more flexible Service-Oriented Architecture enabled them to be more agile and adapt their business and Identity Management helped with sometimes mundane (but costly) issues like lost passwords and being able to document who has access to what. Things don't always turn out so rosy. And I know it was a long and difficult process...but it's nice to see a happy ending every once in a while.

• How to convert poor quality bitmap image to vector?

  - by Macha

  I'm designing a website for a group which has lost the original digital image for their logo. The only file they have of it is a jpg which was embedded into a word document. The image has everything possible wrong with it: Anti-aliased onto a white background where it should be transparent Image artefacts Resized downwards poorly. Lines that should be straight and solid aren't. I've currently used the wand tool to get rid of the white background, and stuck it on the website, but it's poor quality makes it stick out like a sore thumb. I need a few different sizes of it to use, so how would I go about creating a vector image based on it?

• configure time sync for azure VMs

  - by Pharao2k

  I have several ExtraSmall-sized Azure VMs (PaaS / Cloud Service based) that are all experiencing drifting of the Windows clock. Research showed that this is quite common, especially in VMs with shared cores. Unfortunately even after configuring the w32time service to sync with time.windows.com and forcing a resync (w32tm /resync), there seems to be a time difference of 2 seconds to the configured NTP server. Though Microsoft states that w32tm is not meant as a high-precision sync tool, a difference of 2 seconds is (IMO) quite a lot for server-activities/processing. What does one have to do to get more accurate time sync?

• Is there any simple game that involves psychological factors?

  - by Roman

  I need to find a simple game in which several people need to interact with each other. The game should be simple for an analysis (it should be simple to describe what happens in the game, what players did). Because of the last reason, the video games are not appropriate for my purposes. I am thinking of a simple, schematic, strategic game where people can make a limited set of simple moves. Moreover, the moves of the game should be conditioned not only by a pure logic (like in chess or go). The behavior in the game should depend on psychological factors, on relations between people. In more details, I think it should be a cooperation game where people make their decisions based on mutual trust. It would be nice if players can express punishment and forgiveness in the game. Does anybody knows a game that is close to what I have described above? ADDED I need to add that I need a game where actions of players are simple and easy to formalize. Because of that I cannot use verbal games (where communication between players is important). By simple actions I understand, for example, moves on the board from one position to another one, or passing chips from one player to another one and so on.

• Finding a laptop to fit my spec's

  - by Mick

  I have a small list of characteristics that are required for a new laptop and have been looking for websites where I can specify my requirements and see which laptops fit the bill. I want to specify OS/RAM/HDD size/CD drive/screen resolution/battery life. I have found several sites so far where I can specify everything except battery life. Does such a site exist? I know that this is not a shopping site - but before any moderator rushes to close this question - please note that I am not asking "where do I buy this laptop" - merely what laptop fits this specs. I don't even care what country the website is based in.

• How can I calculate a vertex normal for a hard edge?

  - by K.G.

  Here is a picture of a lovely polygon: Circled is a vertex, and numbered are its adjacent faces. I have calculated the normals of those faces as such (not yet normalized, 0-indexed): Vertex 1 normal 0: 0.000000 0.000000 -0.250000 Vertex 1 normal 1: 0.000000 0.000000 -0.250000 Vertex 1 normal 2: -0.250000 0.000000 0.000000 Vertex 1 normal 3: -0.250000 0.000000 0.000000 Vertex 1 normal 4: 0.250000 0.000000 0.000000 What I'm wondering is, how can I determine, taken as given that I want this vertex to represent a hard edge, whether its normal should be the normal of 1/2 or 3/4? My plan after I glanced at the sketch I used to put this together was "Ha! I'll just use whichever two faces have the same normal!" and now I see that there are two sets of two faces for which this is true. Is there a rule I can apply based on the face winding, angle of the adjacent edges, moon phase, coin flip, to consistently choose a normal direction for this box? For the record, all of the other polygons I plan to use will have their normals dictated in Maya, but after encountering this problem, it made me really curious.

• Reverting problems caused by checkinstall with gcc build

  - by slavik262

  I recently downloaded the GCC 4.6.2 source in order to play around a bit with C++11. Having been told about checkinstall and its usefulness in installing programs from source, I created a Debian package from the install using sudo checkinstall -D make install. Wanting to see how well the newly created package worked, I removed it using Synaptic Package Manager. As it turns out, the package checkinstall created from make install tried to remove every single file the installation process touched, including shared gcc libraries like /lib64/libgcc_s.so. Despite not being able to run a bunch of programs due to this missing dependency, I was able to restore my system back to normal by reinstalling the package from command line using dpkg. At this point I want to remove the package from the package manager since it's so dangerous, but not remove the installed files. I was looking around in /var/lib/dpkg and found that the package manager seems to be based on text files which list packages and such - can I just remove all mention of the package from the files in /var/lib/dpkg, or is there a safer way to go about this?

• Source-control your BI Publisher reports

  - by Dmitry Nefedkin

  Version control systems (VCS) like Subversion, Git and the others has been widely adopted and became the must-have tool in any software development project. Source artifacts and checked out, modified, checked in, all the history of changes is tracked by the VCS.  But what if the development tool stores the source/configuration artifacts not in your laptop's hard drive, but in some shared repository instead? Well, we definitely need a way for export/import our artifacts from/to this repository.   Oracle BI Publisher report development approach is based on such a shared repository model (catalog), and starting from BI Publisher 11.1.1.5 Oracle ships Catalog Utility, which can be utilized to export/import the reports from the command line.  To start using the BI Publisher Catalog Utility you should: Go to the file system of the server where BI Publisher binaries has been installed and locate the following file: <MW_HOME>/Oracle_BI1/clients/bipublisher/BIPCatalogUtil.zip Copy the file to your local filesystem and unzip it. I will refer to this unzipped directory as <BIP_CLIENT_DIR> below If you do not want to pass server BI Publisher server URL, username and password during each invocation, modify the corresponding values inside <BIP_CLIENT_DIR>/config/xmlp-client-config.xml Open the terminal window and go to <BIP_CLIENT_DIR>/bin Make sure that the following environment variables are set: JAVA_HOME, ORACLE_HOME Now it's time to run the utility: if you are on Linux - just run BIPCatalogUtil.sh and pass the parameters according to the utility documentation if you are on MS Windows the bad news are that the command script for MS Windows is missing, and support.oracle.com note 1333726.1 says that a temporary solution is "create a .cmd file by setting up a classpath and copying the same commands from the .sh script". The good news are that I've created this script already,  please download the it from GitHub Hope you will find this utility useful during you day-by-day BI Publisher development.

• Simplify Your Code with LINQ

  - by dwahlin

  I’m a big fan of LINQ and use it wherever I can to minimize code and make applications easier to maintain overall. I was going through a code file today refactoring it based on suggestions provided by Resharper and came across the following method: private List<string> FilterTokens(List<string> tokens) { var cleanedTokens = new List<string>(); for (int i = 0; i < tokens.Count; i++) { string token = tokens[i]; if (token != null) { cleanedTokens.Add(token); } } return cleanedTokens; }   In looking through the code I didn’t see anything wrong but Resharper was suggesting that I convert it to a LINQ expression: In thinking about it more the suggestion made complete sense because I simply wanted to add all non-null token values into a List<string> anyway. After following through with the Resharper suggestion the code changed to the following. Much, much cleaner and yet another example of why LINQ (and Resharper) rules: private List<string> FilterTokens(IEnumerable<string> tokens) { return tokens.Where(token => token != null).ToList(); }

• Transaction classification. Artificial intelligence

  - by Alex

  For a project, I have to classify a list of banking transactions based on their description. Supose I have 2 categories: health and entertainment. Initially, the transactions will have basic information: date and time, ammount and a description given by the user. For example: Transaction 1: 09/17/2012 12:23:02 pm - 45.32$ - "medicine payments" Transaction 2: 09/18/2012 1:56:54 pm - 8.99$ - "movie ticket" Transaction 3: 09/18/2012 7:46:37 pm - 299.45$ - "dentist appointment" Transaction 4: 09/19/2012 6:50:17 am - 45.32$ - "videogame shopping" The idea is to use that description to classify the transaction. 1 and 3 would go to "health" category while 2 and 4 would go to "entertainment". I want to use the google prediction API to do this. In reality, I have 7 different categories, and for each one, a lot of key words related to that category. I would use some for training and some for testing. Is this even possible? I mean, to determine the category given a few words? Plus, the number of words is not necesarally the same on every transaction. Thanks for any help or guidance! Very appreciated Possible solution: https://developers.google.com/prediction/docs/hello_world?hl=es#theproblem

• Data transfer between "main" site and secured virtual subsite

  - by Emma Burrows

  I am currently working on a C# ASP.Net 3.5 website I wrote some years ago which consists of a "main" public site, and a sub-site which is our customer management application, using forms-based authentication. The sub-site is set up as a virtual folder in IIS and though it's a subfolder of "main", it functions as a separate web app which handles CRUD access to our customer database and is only accessible by our staff. The main site currently includes a form for new leads to fill in, which generates an email to our sales staff so they can contact them and convince them to become customers. If that process is successful, the staff manually enter the information from the email into the database. Not surprisingly, I now have a new requirement to feed the data from the new lead form directly into the database so staff can just check a box for instance to turn the lead into a customer. My question therefore is how to go about doing this? Possible options I've thought of: Move the new lead form into the customer database subsite (with authentication turned off). Add database handling code to the main site. (No, not seriously considering this duplication of effort! :) Design some mechanism (via REST?) so a webpage outside the customer database subsite can feed data into the customer database How to organise the code for this situation, preferably with extensibility in mind, and particularly are there any options I haven't thought of?

• DIA2012

  - by Chris Kawalek

  If you've read this blog before, you probably know that Oracle desktop virtualization is used to demonstrate Oracle Applications at many different trade shows. This week, the Oracle desktop team is at DIA2012 in Philadelphia, PA. The DIA conference is a large event, hosting about 7,000 professionals in the pharmaceutical, bio technology, and medical device fields. Healthcare and associated fields are leveraging desktop virtualization because the model is a natural fit due to their high security requirements. Keeping all the data on the server and not distributing it on laptops or PCs that could be stolen makes a lot of sense when you're talking about patient records and other sensitive information. We're proud to be supporting the Oracle Health Sciences team at DIA2012 by hosting all of the Oracle healthcare related demos on a central server, and providing simple, smart card based access using our Sun Ray Clients. And remember that you're not limited to using just Sun Ray Clients--you can also use the Oracle Virtual Desktop Client and freely move your session from your iPad, your Windows or Linux PC, your Mac, or Sun Ray Clients. It's a truly mobile solution for an industry that requires mobile, secure access in order to remain compliant. Here are some pics from the show: We also have an informative PDF on Oracle desktop virtualization and Oracle healthcare that you can have a look at.  (Many thanks to Adam Workman for the pics!) -Chris  For more information, please go to the Oracle Virtualization web page, or  follow us at :  Twitter   Facebook YouTube Newsletter

• MEF, IServiceProvider and Testing Visual Studio Extensions

  - by Daniel Cazzulino

  In the latest and greatest version of Visual Studio, MEF plays a critical role, one that makes extending VS much more fun than it ever was. So typically, you just [Export] something, and then someone [Import]s it and that's it. MEF in all its glory kicks in and gets all your dependencies satisfied. Cool, you say, so let's now import ITextTemplating and have some T4-based codegen going! Ah, if only it was that easy. Turns out by default, none of the VS built-in services are exposed to MEF, apparently because there wasn't enough time to analyze the lifetime, initialization, dependencies, etc. for each one before launch, which makes perfect sense. You don't want to blindly export everything now just in case. There's also the whole VS package initialization thing which in this version of VS is not so transparently integrated with the MEF publishing side (i.e. a MEF export from a package can get instantiated before its owning package, and in fact, the package can remain unloaded forever and the export will continue to be visible to anyone)....Read full article

• What the Hekaton?

  - by Tony Davis

  Hekaton, the power behind SQL Server 2014′s In-Memory OLTP technology, is intended to make data operations run orders of magnitude faster on SQL Server. This works its magic partly by serving database workloads entirely from main memory, using memory-optimized table structures. It replaces the relational engine’s standard locking model with an optimistic concurrency model based on time-stamped row versions. Deeper down the Hekaton engine uses new, ‘latch free’ data structures. So far, so good, but performance improvements on this scale require a compromise, and the compromise is that these aren’t tables as we understand them. For the database developer, these differences are painful because they involve sacrificing some very important bits of the relational model. Most importantly, Hekaton tables don’t currently support FOREIGN KEY constraints or CHECK constraints, and you can’t put the checks in triggers because there aren’t any DML triggers either. Constraints allow a relational designer to enforce relational integrity and data integrity. Without them, of course, ‘bad data’ can get into our Hekaton tables. There is no easy way of preventing it. For several classes of database and data, this is a show-stopper. One may regard all these restrictions regretfully, seeing limited opportunity to try out Hekaton with current databases, but perhaps there is also a sudden glow of recognition. Isn’t this how we all originally imagined table variables were going to be, back in SQL 2005? And they have much the same restrictions. Maybe, instead of pretending that a currently-designed database can be ‘Hekatonized’ with a few mouse clicks, we should redesign databases for SQL 2014 to replace table variables with Hekaton tables, exploiting this technology for fast intermediate processing, and for the most part forget, for now, the idea of trying to convert our base relational tables into Hekaton tables. Few database developers would be averse to having their working tables running an order of magnitude faster, as long as it didn’t compromise the integrity of the data in the base tables.

• Fuzzing for Security

  - by Sylvain Duloutre

  Yesterday, I attended an internal workshop about ethical hacking. Hacking skills like fuzzing can be used to quantitatively assess and measure security threats in software.  Fuzzing is a software testing technique used to discover coding errors and security loopholes in software, operating systems or networks by injecting massive amounts of random data, called fuzz, to the system in an attempt to make it crash. If the program contains a vulnerability that can leads to an exception, crash or server error (in the case of web apps), it can be determined that a vulnerability has been discovered.A fuzzer is a program that generates and injects random (and in general faulty) input to an application. Its main purpose is to make things easier and automated.There are typically two methods for producing fuzz data that is sent to a target, Generation or Mutation. Generational fuzzers are capable of building the data being sent based on a data model provided by the fuzzer creator. Sometimes this is simple and dumb as sending random bytes, swapping bytes or much smarter by knowing good values and combining them in interesting ways.Mutation on the other hand starts out with a known good "template" which is then modified. However, nothing that is not present in the "template" or "seed" will be produced.Generally fuzzers are good at finding buffer overflow, DoS, SQL Injection, Format String bugs etc. They do a poor job at finding vulnerabilites related to information disclosure, encryption flaws and any other vulnerability that does not cause the program to crash.  Fuzzing is simple and offers a high benefit-to-cost ratio but does not replace other proven testing techniques.What is your computer doing over the week-end ?

• Redirect output of Python program to /dev/null

  - by STM

  I have a Python executable, written and compiled by somebody else, that I simply need to run once halfway down my own bash script. The program uses a text-based UI, therefore waits for input before proceeding, but the key operations it performs when starting are required in my bash script. A messy (and strange) procedure I know, but unfortunately I haven't got any other options. I've gotten around forcefully closing the program with a kill signal, but the program's TUI insists on outputting to wherever it's run. I've tried redirecting both stdout and stderr to /dev/null and running the program in the background by suffixing an ampersand, but simply can't get it to play ball. I believe the cause is the program spawns other processes, and the output redirection of the parent process doesn't affect them. Is there any trick I can utilise to redirect all output from child processes too?

• Is there a way to legally create a game mod?

  - by Rodrigo Guedes

  Some questions about it: If I create a funny version of a copyrighted game and sell it (crediting the original developers) would it be considered a parody or would I need to pay royalties? If I create a game mod for my own personal use would it be legal? What if I gave it for free to a friend? Is there a general rule about it or it depends on the developer will? P.S.: I'm not talking about cloning games like this question. It's all about a game clearly based on another. Something like "GTA Gotham City" ;) EDIT: This picture that I found over the internet illustrate what I'm talking about: Just in case I was not clear: I never created a mod game. I was just wondering if it would be legally possible before trying to do it. I'm not apologizing piracy. I pay dearly for my games (you guys have no idea how expensive games are in Brazil due to taxes). Once more I say that the question is not about cloning. Cloning is copy something and try to make your version look like a brand new product. Mods are intended to make reference to one or more of its source. I'm not sure if it can be done legally (if I knew I wasn't asking) but I'm sure this question is not a duplicate. Even so, I trust in the moderators and if they close my question I will not be offended - at least I had an opportunity to explain myself and got 1 good answer (by the time I write this, maybe some more will be given later).

• Graduated transition from Green - Yellow - Red

  - by GoldBishop

  I have am having algorithm mental block in designing a way to transition from Green to Red, as smoothly as possible with a, potentially, unknown length of time to transition. For testing purposes, i will be using 300 as my model timespan but the methodology algorithm design needs to be flexible enough to account for larger or even smaller timespans. Figured using RGB would probably be the best to transition with, but open to other color creation types, assuming its native to .Net (VB/C#). Currently i have: t = 300 x = t/2 z = 0 low = Green (0, 255, 0) mid = Yellow (255, 255, 0) high = Red (255, 0, 0) Lastly, sort of an optional piece, is to account for the possibility of the low, mid, and high color's to be flexible as well. I assume that there would need to be a check to make sure that someone isnt putting in low = (255,0,0), mid=(254,0,0), and high=(253,0,0). Outside of this anomaly, which i will handle myself based on the best approach to evaluate a color.
