• Isolating test data in acceptance tests

  - by Matt Phillips

  I'm looking for guidance on how to keep my acceptance tests isolated. Right now the issue I'm having with being able to run the tests in parallel is the database records that are manipulated in the tests. I've written helpers that take care of doing inserts and deletes before tests are executed, to make sure the state is correct. But now I can't run them in parallel against the same database without uniquely generating the test data fields for each test. For example. Testing creating a row i'll delete everything where column A = foo and column B = bar Then I'll navigate through the UI in the test and create a record with column A = foo and column B = bar. Testing that a duplicate row is not allowed to be created. I'll insert a row with column A = foo and column B = bar and then use the UI to try and do the exact same thing. This will display an error message in the UI as expected. These tests work perfectly when ran separately and serially. But I can't run them at the same time for fear that one will create or delete a record the other is expecting. Any tips on how to structure them better so they can be run in parallel?

• Constructive criticsm on my linear sampling Gaussian blur

  - by Aequitas

  I've been attempting to implement a gaussian blur utilising linear sampling, I've come across a few articles presented on the web and a question posed here which dealt with the topic. I've now attempted to implement my own Gaussian function and pixel shader drawing reference from these articles. This is how I'm currently calculating my weights and offsets: int support = int(sigma * 3.0) weights.push_back(exp(-(0*0)/(2*sigma*sigma))/(sqrt(2*pi)*sigma)); total += weights.back(); offsets.push_back(0); for (int i = 1; i <= support; i++) { float w1 = exp(-(i*i)/(2*sigma*sigma))/(sqrt(2*pi)*sigma); float w2 = exp(-((i+1)*(i+1))/(2*sigma*sigma))/(sqrt(2*pi)*sigma); weights.push_back(w1 + w2); total += 2.0f * weights[i]; offsets.push_back(w1 / weights[i]); } for (int i = 0; i < support; i++) { weights[i] /= total; } Here is an example of my vertical pixel shader: vec3 acc = texture2D(tex_object, v_tex_coord.st).rgb*weights[0]; vec2 pixel_size = vec2(1.0 / tex_size.x, 1.0 / tex_size.y); for (int i = 1; i < NUM_SAMPLES; i++) { acc += texture2D(tex_object, (v_tex_coord.st+(vec2(0.0, offsets[i])*pixel_size))).rgb*weights[i]; acc += texture2D(tex_object, (v_tex_coord.st-(vec2(0.0, offsets[i])*pixel_size))).rgb*weights[i]; } gl_FragColor = vec4(acc, 1.0); Am I taking the correct route with this? Any criticism or potential tips to improving my method would be much appreciated.

• Two different domains as one user session in Google Analytics

  - by Mathew Foscarini

  I have two websites that are run as the same service. Each domain offers articles from a different market. At the top of each page the two domains are shown as menu options. If a user clicks one they can switch to the other domain. See here: http://www.cgtag.com Each domain has a different Google Analytics account, and when a user switches domains Google is counting this as a new session. It's listing the other domain as the "referral" for that new session. When the user switches back to the first domain Google is counting this as a returning visitor. This is messing up my reports. Showing returning visitors values that are higher than reality. It's also increasing hits on landing pages when the user switches, and listing the other domain as a referral site. I've found tips on how to list two domains as one website, but that results in merging the data. I want to keep the two domains separate so that I can track each ones performance, but I don't want to count domain changes as new sessions. Maybe something like treating the two domains as subdomains.

• DropSpace Syncs Android Files to Dropbox

  - by ETC

  DropSpace is a free Android application that fixes the primary issue that plagues the official Dropbox app for Android–the lack of true file synchronization. Grab a copy of DropSpace and start enjoying true file syncing on the go. The official Dropbox app is limited to grabbing files from your Dropbox account or pushing files from your phone to your Dropbox account. Actual file synchronization, this manual push/pull model aside, is nowhere to be found. DropSpace fills that gap by enabling file synchronization between your SD card directories and your Dropbox directories. It’s packed with handy features including restricting file syncing to Wi-Fi connection only (great if you don’t want to chew up your very limited data plan) as well as numerous toggles for various settings like whether it should delete remote files if the local file is deleted, how often it should run the sync service, and more. Hit up the link below to grab a copy and take it for a test drive. DropSpace is free and works wherever Android does; Dropbox account required.

• Five Ideas: Project Management

  - by Sylvie MacKenzie, PMP

   Except from Profit Magazine “For everyone to put on the project manager hat and standardize the way every single thing is done means that now the whole organization is on the same page as to what needs to occur from the time a hurricane hits Haiti and when a boat pulls in to unload supplies.” —Rich D’Addario, consulting project manager in the Primavera Global Business Unit at Oracle, on helping AmeriCares deliver aid to Haiti “Primavera P6 Analytics generates information that can help organizations improve their utilization and trim down overall operating costs. But more importantly, it gives organizations improved visibility.” —Yasser Mahmud, vice president of product strategy and industry marketing in Oracle’s Primavera Global Business Unit “Organizations are constantly looking for ways to improve the speed and precision of their decisions and work without creating environments and systems that limit their personnel through rigid structures and inflexible processes. The latest release of Primavera Portfolio Management meets this demand by further streamlining processes and supporting enhanced decision-making, helping drive better value from portfolios. In addition, the new UI clearly demonstrates Oracle's commitment to providing a seamlessly integrated enterprise project portfolio management product suite.” —Mike Sicilia, senior vice president, Oracle's Primavera “Make it a business project, not an IT project. All levels of functional management must have ownership, responsibility, and accountability for the success of the implementation.” —from Eaton Operations Services Manager Marcos Baccetto's 9 Project Management Tips “AEC firms must strategically pursue standardization opportunities in the project management area while preserving the spirit of entrepreneurism and flexibility at an individual project manager level. An enterprise technology platform doesn't only help with standardization of key project management processes across the enterprise; it also improves performance management, team collaboration and client specific reporting at an individual project level.” —Maneesh Chhabra is a director of Industry Strategy and Insight at Oracle

• Customizing the NUnit GUI for data-driven testing

  - by rwong

  My test project consists of a set of input data files which is fed into a piece of legacy third-party software. Since the input data files for this software are difficult to construct (not something that can be done intentionally), I am not going to add new input data files. Each input data file will be subject to a set of "test functions". Some of the test functions can be invoked independently. Other test functions represent the stages of a sequential operation - if an earlier stage fails, the subsequent stages do not need to be executed. I have experimented with the NUnit parametrized test case (TestCaseAttribute and TestCaseSourceAttribute), passing in the list of data files as test cases. I am generally satisfied with the the ability to select the input data for testing. However, I would like to see if it is possible to customize its GUI's tree structure, so that the "test functions" become the children of the "input data". For example: File #1 CheckFileTypeTest GetFileTopLevelStructureTest CompleteProcessTest StageOneTest StageTwoTest StageThreeTest File #2 CheckFileTypeTest GetFileTopLevelStructureTest CompleteProcessTest StageOneTest StageTwoTest StageThreeTest This will be useful for identifying the stage that failed during the processing of a particular input file. Is there any tips and tricks that will enable the new tree layout? Do I need to customize NUnit to get this layout?

• ORA-600 Troubleshooting

  - by [email protected]

  Have you observed an ORA-0600 or ORA-07445 reported in your alert log? The ORA-600 error is the generic internal error number for Oracle program exceptions. It indicates that a process has encountered a low-level, unexpected condition. The ORA-600 error statement includes a list of arguments in square brackets: ORA 600 "internal error code, arguments: [%s], [%s],[%s], [%s], [%s]" The first argument is the internal message number or character string. This argument and the database version number are critical in identifying the root cause and the potential impact to your system.  The remaining arguments in the ORA-600 error text are used to supply further information (e.g. values of internal variables etc).   Looking for the best way to diagnose? There is an ORA-600 Troubleshooter Tool available in My Oracle Support.  This tool will lead you to applicable content in My Oracle Support on the problem and can be used to investigate the problem with argument data from the error message or you can pull out the first 10 or 15 stack pointers from the associated trace file to match up against known bugs.

• How to visualize the design of a program in order to communicate it to others

  - by Joris Meys

  I am (re-)designing some packages for R, and I am currently working out the necessary functions, objects, both internal and for the interface with the user. I have documented the individual functions and objects. So I have the description of all the little parts. Now I need to give an overview of how the parts fit together. The scheme of the motor so to say. I've started with making some flowchart-like graphs in Visio, but that quickly became a clumsy and useless collection of boxes, arrrows and-what-not. So hence the question: Is there specific software you can use for vizualizing the design of your program If so, care to share some tips on how to do this most efficiently If not, how do other designers create the scheme of their programs and communicate that to others? Edit: I am NOT asking how to explain complex processes to somebody, nor asking how to illustrate programming logic. I am asking how to communicate the design of a program/package, i.e.: the objects (with key features and representation if possible) the related functions (with arguments and function if possible) the interrelation between the functions at the interface and the internal functions (I'm talking about an extension package for a scripting language, keep that in mind) So something like this : But better. This is (part of) the interrelations between functions in the old package that I'm now redesigning for obvious reasons :-) PS : I made that graph myself, using code extraction tools on the source and feeding the interrelation matrix to yEd Graph Editor.

• Attempting to install netgear N300 Wireless USB Adapter on Ubuntu without a present internet connection

  - by Liz

  Hello Linux/Ubuntu world out there. I don't have internet presently on the desktop I am trying to install the USB wireless adapter on. This seems to be the problem, which if the hardware would work would theoretically fix the problem. I can NOT access the internet via anything but wireless. I am presently on my laptop searching for answers while trying to install this little device. So any advice will have to take that into account. Now I have tried so far, using WINE which does not want to work, I have tried Windows Wireless Drivers which doesn't want to work, I have tried Software Sources, Other Software and it will not acknowledge the cdrom as a repository stating errors like E:Unable to stat the mount point /cdrom/ -stat (2: No such file or directory) However I can open the CD icon on my computer and access and browse the files. The computer can read the CD. I can read the CD. I've tried just plugging it in and seeing if the computer will automatically recognize the hardware, and go from there. That does not work either. I have tested USB port to just verify that the USB port works. It does. My laptop recognizes the hardware, and would easily install the software if I prompted it to. The difference is that my laptop is Vista, and I HATE Vista. Any tips, tricks?

• How do you properly organize a commercial game?

  - by Reactorcore

  For the past months I've been studying programming and I've finally learned how to code, but one thing that is confusing me is how to properly organize the design of a game project - code wise. The game I'm building is a pretty standard commercial game. It has the basic components of a normal game: A world, characters and items interacting with each other and all of this is run by game manager. Basically you play as a hero in a world and do stuff. Fight, explore and interact. Think of your standard adventure game that starts off with an intro, goes to the menu system, then gets into the game and back to the menu. Pretty much like 99% of any commercial game or otherwise serious game projects. Thats what I'm aiming at. The problem is: How do you properly code a commercial game architecture? How do you organize it? How do you make it not become unmaintainable spaghetti code? What specific things to keep in mind when building this, codewise? How you can help me: a) Please tell how do you code your own game projects. What is your thought-process when designing the architecture? b) Recommend books, blogs, tutorials, videos or anything else on how to organize a commercial video game. c) Give hints and tips on do's/don'ts when building a game, codewise. Please help!

• Static IP configuration causing apt-get errors

  - by JPbuntu

  I am getting errors when running apt-get update or when installing new packages. Although this only happens when the server configured for a static IP address. Changing the configuration back to DHCP and restarting networking fixes the problem, although I want a static IP. Once it is working I can change back to my static IP address and restart networking. Although this only works until I restart the server (restarting the router is ok), and then I start getting the same errors and have to switch back to DHCP. Any ideas on what could be causing this or tips on troubleshooting it? Thanks in advance. here is my static IP configuration: auto eth0 iface eth0 inet static address 192.168.2.2 netmask 255.255.255.0 gateway 192.168.2.1 The apt-get update errors go something like this: A few of these Ign http://us.archive.ubuntu.com precise-backports InRelease then a lot of these Err http://security.ubuntu.com precise-security Release.gpg Something wicked happened resolving 'security.ubuntu.com:http' (-5 - No address associated with hostname) and a lot of these W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-backports/universe/i18n/Translation-en Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)

• Updating password hashing without forcing a new password for existing users

  - by Willem

  You maintain an existing application with an established user base. Over time it is decided that the current password hashing technique is outdated and needs to be upgraded. Furthermore, for UX reasons, you don't want existing users to be forced to update their password. The whole password hashing update needs to happen behind the screen. Assume a 'simplistic' database model for users that contains: ID Email Password How does one go around to solving such a requirement? My current thoughts are: create a new hashing method in the appropriate class update the user table in the database to hold an additional password field Once a user successfully logs in using the outdated password hash, fill the second password field with the updated hash This leaves me with the problem that I cannot reasonable differentiate between users who have and those who have not updated their password hash and thus will be forced to check both. This seems horribly flawed. Furthermore this basically means that the old hashing technique could be forced to stay indefinitely until every single user has updated their password. Only at that moment could I start removing the old hashing check and remove the superfluous database field. I'm mainly looking for some design tips here, since my current 'solution' is dirty, incomplete and what not, but if actual code is required to describe a possible solution, feel free to use any language.

• How to start a high school Java/Android development club for 13-17 year olds

  - by PaulHurleyuk

  My wife is a high school maths teacher, and is considering starting a programming club for 13-17 years olds who show an interest. Their interest seems to be around Apps and Android which I have little experience of. The kids would be (presumably) interested in programming, and have a fairly high level of computing knowledge. We would provide them with resources and some knowledge, but hopefully a lot would be self guided. I'm hoping stack overflow'ers can provide some tips or starting points. Specific things I think I'll need are; A development Environment; Currently I'm looking towards Java and Android, developed in Eclipse, probably installed on donated older hardware Some initial direction; There seem to be a plethora or 'start android' tutorials, so some recommendations for good ones are valuable, as are recommended paper books A Target; Some final project they should be shooting for A Route; This is where I'm most stuck, how to lead them through the required Java concepts and learning they would need Some related questions already out there Language+IDE for teaching high school students? Teaching "web design/development" to high-school home-school group. Good sources? How can I bootstrap a software development community at my school?

• 8 Reasons to Attend Oracle OpenWorld 2012

  - by kgee

  Every year, the Oracle Hardware team recognizes the unique buzz that accompanies the season of OpenWorld. During the late nights kept possible by the grace of caffeine combined with the stress and eagerness for the event to run smoothly, we like to remind ourselves of why all our hard work is going to pay off. So, now that we've registered, here are some of our top reasons that we’re excited for Oracle OpenWorld 2012: The KeynotesJust to name a few...Larry Ellison, Mark Hurd, Thomas Kurian, John Fowler and many more are speaking live. We're expecting to walk away from the keynotes with a new frame of reference on a vast array of hot topics. NetworkingWhether it's through means of the OpenWorld Lounges, social media, or bars and cafes around Moscone Center, we'll be surrounded by people who are experts in the hardware field. Hardware SessionsThere are enough sessions to satisfy every Oracle hardware knowledge need. Hardware Experts in GeneralSo many experts that we wish we could be in two places at once sometimes. Pearl Jam & Kings of LeonRock out with these two legendary bands at the Oracle Appreciation Event! Oracle Music FestivalJoss Stone, Macy Gray, the Hives, and Jimmy Cliff will be welcome escapes at the end of each day at OpenWorld, and are just a couple more reasons these all nighters before OpenWorld are worth it. ORACLE TEAM USA and the America's Cup trophyAfter the sailors take on San Francisco Bay for Fleet Week, we’ll be soliciting them for autographs and taking pictures with them at OpenWorld. Location, Location, LocationThe Moscone Center is beautiful and in the best location in San Francisco. We know the OpenWorld hype will get to us sometimes, and it's nice to know that we have pretty much everything San Francisco has to offer at our finger tips. Why are you excited for #OOW? Tell us why!

• Ideal data structure/techniques for storing generic scheduler data in C#

  - by GraemeMiller

  I am trying to implement a generic scheduler object in C# 4 which will output a table in HTML. Basic aim is to show some object along with various attributes, and whether it was doing something in a given time period. The scheduler will output a table displaying the headers: Detail Field 1 ....N| Date1.........N I want to initialise the table with a start date and an end date to create the date range (ideally could also do other time periods e.g. hours but that isn't vital). I then want to provide a generic object which will have associated events. Where an object has events within the period I want a table cell to be marked E.g. Name Height Weight 1/1/2011 2/1/2011 3/1/20011...... 31/1/2011 Ben 5.11 75 X X X Bill 5.7 83 X X So I created scheduler with Start Date=1/1/2011 and end date 31/1/2011 I'd like to give it my person object (already sorted) and tell it which fields I want displayed (Name, Height, Weight) Each person has events which have a start date and end date. Some events will start and end outwith but they should still be shown on the relevant date etc. Ideally I'd like to have been able to provide it with say a class booking object as well. So I'm trying to keep it generic. I have seen Javasript implementations etc of similar. What would a good data structure be for this? Any thoughts on techniques I could use to make it generic. I am not great with generics so any tips appreciated.
