  • Investment scheme for a PC game the project

    - by Alex Kamen
    Good day everyone, I am working on a PC game project that has 3 phases planned, micro, macro and mmo versions [if confused, see a brief description at the bottom]. I have found a potential investor for the micro version of the game, but naturally, he requested a detailed plan of how the game will pay back. And the problem is that micro version itself is not supposed to be monetized much, other than some ads and limited in-game currency utilization. The idea is that with this combat demo already at hand, it should be possible to get a really large enough investment (millions of dollars) and use it to pay back the initial small one (thousands of dollars) and take the project into macro phase, which will really make profit. This way, everybody is going to win, provided that I can deliver the end-product. Yet while I am confident of that both the conception of the macro and the real game-play of the micro versions are going to be appealing, I don’t know how to obtain any guarantee of that I will be able to get funded once I have the prototype ready. And without that, I won’t receive the funds for the prototype in the first place! To summarize, my question is: how to figure out my future possibilities of getting funded once I have combat demo out, basically “whom to write to and what”. Ideally, I would like some sort of a preliminary agreement with a game publisher, something that would basically state “If the developer provides the product in time and in quality corresponding to the specifications given, the publisher guarantees to allocate funds for distribution and further development, thereby acquiring the right to X part of all future profits”. Does this sound sane? It’s just that I don’t want to sell all of my rights out straight away by taking a big outside investment while the project is in such early stage. I would appreciate if you would share your thoughts on this kind of scheme, and be sure to ask questions as I am sure I must have forgotten to mention a ton of important things, like the fact that initial funds are going to be spent on outsourcing (living in Siberia is really just great). [here’s a brief outline of what each version will feature] [micro] 1) turn based tactical combat rules 2) character development 3) arena/tournament system [macro] 4) ai-ruled dynamic interactive worlds 5) global map adventuring 6) strategic rpg + god simulator gameplay [mmo] 7) Persistent worlds system 8) Social structures system (“guilds/clans”) 9) god-simulation on the mmo scale P.S. Obviously, these features are incremental, so that mmo version has all 9.

  • How to run software, that is not offered though package managers, that requires ia32-libs

    - by Onno
    I'm trying to install the Arma 2 OA dedicated server on a Virtualbox VM so I can test my own missions in a sandbox environment in a way that lets me offload them to another computer in my network. (The other computer is running the VM, but it's a windows machine, and I didn't want to hassle with its installation) It needs at least 2, and preferably 4GB of ram, so I thought I would install the AMD64 version of ubuntu 13.10 to get this going. 'How do you run a 32-bit program on a 64-bit version of Ubuntu?' already explained how to install 32bit software though apt-get and/or dpkg, but that doesn't apply in this case. The server is offered as a compressed download on the site of BI Studio, the developer of the Arma games. Its installation instructions are obviously slightly out of date with the current state of the art. (probably because the state of the art has been updated quite recently :) ) It states that I have to install ia32-libs, which has now apparently been deprecated. Now I have to find out how to get the right packages installed to make sure that it will run. My experience level is like novice-intermediate when it comes to these issues. I've installed a lot of packages though apt-get; I've solved dependency issues in the past; I haven't installed much software without using package managers. I can handle myself with basic administrative work like editing conf files and such. I have just gone ahead and tried to install it without installing ia32-libs through apt-get but to install gcc to get the libs after all. My reasoning being that gcc will include the files for backward compatibility coding and on linux all libs are (as far as I can tell) installed at a system level in /libs . So far it seems to start up. (I can connect with the game server trough my in-game network browser, so it's communicating) I'm not sure if there's any dependency checking going on when running the game server program, so I'm left with a couple of questions: Does 13.10 catch any calls to ia32libs libraries and translate the calls to the right code on amd64? If it runs, does that mean that all required libraries have been loaded correctly, or is there a change of it crashing later on when a library that was needed is missing after all? Is it necessary to do a workaround such as installing gcc? How do I find out what libraries I might need to run this software? (or any other piece of 32-bit software that isn't offered through a package manager)

  • From Co-op to fulltime help with salary negotation [closed]

    - by Peter
    Hey I'm a coop student that worked at a particular medium size printing company for 8 months. I had a good time it was lax, sometimes insufficiently challenging but none the less I learned a whole lot. I stuck with them for another 5 months (including this month) at the same rate I was paid then, doing testing work, tool development, taking care of emergencies when the lead developers were away, and other smaller projects and now bigger projects and problem handling (bad printer output etc.). I know their website inside out (ecommerce), and I know their printing software inside out and have made many changes to them both without a hitch. I have also done a lot of refactoring of the existing code base which as far as Im concerned, I believe am the only one to do those sorts of restructuring even though there is constant talk about it. I guess the unit testing paid off and lets me see the value in modularity if even a tad more. Never the less I have faith in my skill and the restructuring I did turned out better than I had imagined . Now the problem is that I finish school next month and so I asked for a full time spot the month after. They have been expanding and have hired a new guy a few months after my coop spot, and just now they hired a new guy to deal with the CRM application. The lead developer who wrote all of the software had left 5 months ago so it was up to all of us to learn what he had done over 4 years (including db, networking). So now I'm afraid that if I assert myself for a salary similar to the other guys, which I believe I am certainly on par with, that I would be seen as ingrateful. It's hard to flip a switch and say, hey double my pay, although when I'm working with their bread and butter (printers) and writing new features, refactoring the whole application for extensibility. I love it regardless of pay. I also feel maybe I'm replaceeble, although nobody knows the website better than myself and the lead web dev (not by a long shot), and nobody knows the printer software/drivers better than myself. I just thought they would have brought up a raise earlier on, and now it feels like they don't value my work. I'm also tired of worrying about it. I think my question is, well what do I do next?

  • WHERE x = @x OR @x IS NULL

    - by steveh99999
    Every SQL DBA and developer should read the blog of MVP Erland Sommarskog – but particularly  his article on dynamic search conditions in T-SQL. I’ve linked above to his SQL 2005 article but his 2008 version is also a must-read. I seem to regularly come across uses of the SQL in the title above… Erland’s article explains in detail why this is inefficient, but I came across a nice example recently… A stored procedure contained the following code :- WHERE @Name is null or [Name] like @Name as a nonclustered index exists on the Name column, you might assume this would be handled efficiently by SQL Server. However, I got the following output from SET STATISTICS IO Table 'xxxxx'. Scan count 15, logical reads 47760, physical reads 9, read-ahead reads 13872, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Note the high number of logical reads… After a bit of investigation, we found that @Name could never actually be set to NULL in this particular example. ie the @x IS NULL was spurious… So, we changed the call to WHERE  [Name] like @Name Now, how much more efficient is this code ? Table 'xxxxx'. Scan count 3, logical reads 24, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0 A nice easy win in this case…… a full index scan has been replaced by a significantly more efficient index seek. I managed to recreate the same behaviour on Adventureworks – here’s a quick query to demonstrate :- USE adventureworks SET STATISTICS IO ON DECLARE @id INT = 51721 SELECT * FROM Sales.SalesOrderDetail WHERE @id IS NULL OR salesorderid = @id SELECT * FROM Sales.SalesOrderDetail WHERE salesorderid = @id Take a look at the STATISTICS IO output and compare the actual query plans used to prove the impact of  WHERE @id IS NULL. And just to follow some of Erland’s advice – here’s how you could get similar performance if it was possible that @id could actually sometimes contain NULL. DECLARE @sql NVARCHAR(4000), @parameterlist NVARCHAR(4000) DECLARE @id INT = 51721 – or change to NULL to prove query is functionally correct SET @sql = 'SELECT * FROM Sales.SalesOrderDetail WHERE 1 = 1' IF @id IS NOT NULL SET @sql = @sql + ' AND salesorderid = @id' IF @id IS NULL SET @sql = @sql + ' AND salesorderid IS NULL' SET @parameterlist = '@id INT' EXEC sp_executesql @sql, @parameterlist,@id Sometimes I think we focus too much on hardware and SQL Server configuration – when really the answer is focus on writing efficient SQL.

  • RTS Game Style Application [closed]

    - by Daniel Wynand van Wyk
    My question may seem somewhat odd, but I hope that my specifications will clarify EXACTLY what it is that I am after. I need some help choosing the right tooling for a particular endeavour. My background is in desktop application development and large back-end systems. I have worked primarily on the Microsoft stack using C# and the .Net framework. My goal is to develop a 2D, RTS style, interactive office simulation. The simulation will model various office spaces, office equipment, employees and their interactions with one another. The idea is to abstract the concept of an office completely. Under the hood the application will do many things that are nothing like a game. This includes P2P networking, VPN tunnelling, streaming video, instant messaging, document collaboration, remote screen sharing, file-sharing, virus scanning, VOIP, document scanning, faxing, emailing, distributed computing, content management and much more! A somewhat similar thing has been attempted by IBM, where they created a virtual office in second life. If their attempt was a game, the game-play would be notably horrible, to say the least! The users/players will drive and control my application through the various objects modelled in the simulation. A single application capable of performing all of these various tasks would be a nightmare to navigate for even the most expert user. Using the concept of a game, I can easily separate functionality by assigning them to objects that relate 1-1 with their real world counter-parts. This can greatly simplify computing for novice users, with many added benefits in terms of visibility, transparency of process and centralized configuration. My hope is to make complex computing tasks accessible to all kinds of users and to greatly reduce the cognitive load associated with using the many different utilities and applications inside office settings. The complexity is therefore limited to the complexity of the space in which you find yourself. I want the application to target as many platforms as possible and run on computers that have no accelerated graphics capabilities. The simulation won't contain any of the fancy eye-candy you find in modern games, to the contrary, my "game" will purposefully be clean and simple. The closest thing I could imagine would be an old game like "Theme Hospital" or the first instalment of "The Sims". All the content will be pre-created and not user-generated like Second Life. New functionality will be added via a plugin system. Given my background and nature of my "game", I would like to spend most of my time writing code that does not have to do with the simulated office, as the "game" is really just a glorified application menu. I have done much reading about existing engines, frameworks and tools. I need the help of an experienced game developer who has tried and tested various products over the years who can guide me in the right direction given my very particular needs. I would appreciate any help I can get!

  • Oracle BPM and Open Data integration development

    - by drrwebber
    Rapidly developing Oracle BPM application solutions with data source integration previously required significant Java and JDeveloper skills. Now using open source tools for open data development significantly reduces the coding needed.  Key tasks can be performed with visual drag and drop designing combined with menu selections entry and automatic form generation directly from XSD schema definitions. The architecture used is extremely lightweight, portable, open platform and scalable allowing integration with a variety of Oracle and non-Oracle data sources and systems. Two videos available on YouTube walk through the process at both an introductory conceptual level and then a deep dive into the programming needed using JDeveloper, Oracle BPM composer and Oracle WLS (WebLogic Server) along with the CAM editor and Open-XDX open source tools. Also available are coding samples and resources from the GitHub project page, along with working online demonstration resources on the VerifyXML site. Combining Oracle BPM with these open source tools provides a comprehensive simple and elegant solution set. Development times are slashed and rapid prototyping is enabled. Also existing data sources can be integrated using open data formats with either XML or JSON along with CRUD accessing via the Open-XDX Java component. The Open-XDX tool is a code-free approach where data mapping is configured as templates using visual drag and drop in the CAM Editor open source tool.  XML or JSON is then automatically generated or processed (output or input) and appropriate SQL statements created to support the data accessing.   Also included is the ability to integrate with fillable PDF forms via the XML templates and the Java PDF form filling library.  Again minimal Java coding is needed to associate the XML source content with the PDF named fields.  The Oracle BPM forms can be automatically generated from XSD schema definitions that are built from the data mapping templates.  This dramatically simplifies development work as all the integration artifacts needed are created by the open source editor toolset. The developer level video is designed as a tutorial with segments, hands-on demonstrations and reviews.  This allows developers to learn the techniques and approaches used in incremental steps. The intended audience ranges from data analysts to developers and assumes only entry level Java skills and knowledge.  Most actions are menu driven while Java coding is limited to simply configuring values and parameters along with performing builds and deployments from JDeveloper and Oracle WLS.   Additional existing Oracle online training resources can be referenced on Oracle BPM and WLS that cover other normal delivery aspects such as user management and application deployment.

  • Releasing the new Sample Browser Phone app

    - by Jialiang
    Originally posted on: http://geekswithblogs.net/Jialiang/archive/2014/06/05/releasing-the-new-sample-browser-phone-app.aspx Starting its journey in 2010, Sample Browser is achieving its tetralogy by releasing a Windows Phone version Sample Browser today. The new Windows Phone app is the fourth milestone of Sample Browser since we released the desktop version and the Visual Studio version in 2012 and the Windows Store version in 2013. This time, by providing a sample browser designed for a ‘walking’ platform in response to MVPs’ suggestions during last year’s MVP Global Summit, we are literally putting a world of code samples "at developers’ fingertips”. If you like to have a code gallery of over 7000 quality code samples in your pocket, then click here to download our Windows Phone Sample Browser and start a fantastic mobile experience. With Windows Phone version Sample Browser and the Internet, you can search for code samples on MSDN at anytime and anywhere you want, 24/7 and–even to bed. You can also check code sample details and share them with your friends. Compared to the other 3 pieces in the tetralogy (desktop version, Visual Studio version, and the Windows Store version), the Windows Phone version Sample Browser sells itself for convenience and instant connectivity. For those who need to reach code samples under mobile circumstances where no PCs is available, Windows Phone version Sample Browser will definitely be the right service you are seeking for. Aside from sharing samples via emails as the other 3 do, the Windows Phone version Sample Browser also allows you to share the sample via SMS and Near Field Communication (NFC).   What's Next Currently, the Windows Phone Sample Browser only supports online MSDN code searching, but we already plan to upgrade Sample Browser to allow users to do ‘Bing code search’, and add and manage their private code snippets.  We will also upgrade the app to universal app. Universal App is a new concept brought up in the Microsoft Build Developer Conference 2014. It is a new development model that allows for a single app to be deployed across multiple Windows devices such as Windows Phone, Windows 8.1, and XBox. Therefore, once we finish upgrading Sample Browser to a universal app, you can synchronize your own code snippets across different devices; You can also mark a code sample as favorite on your Windows Phone and continue to study the sample when you are on your desktop. By then, sharing data between platforms will be a piece of cake. Also, the user experience of Sample Browser on different platforms will be more consistent.  The best is yet to come!   We sincerely suggest you give Sample Browser a try (click here to download). If you love what you see in Sample Browser, please recommend it to your friends and colleagues. If you encounter any problems or have any suggestions for us, please contact us at [email protected]. Your precious opinions and comments are more than welcome.

  • My 2011 Professional Development Goals

    - by kerry
    I thought it might be a good idea to post some professional goals for 2011.  Hopefully, I can look at this list at the end of the year and have accomplished most of them. Release an Android app to the marketplace – I figured I would put this first because I have one that I have been working on for a while and it is about ready.  Along with this, I would like to start another one and continue to develop my Android skills. Contribute free software to the community – Again, I have an SMF plugin that will fill this requirement nicely.  Just need to give it some polish and release it.  That’s not all, I would like to add a few more libraries on github, or possibly contribute to an open source project. Regularly attend a user group meetings outside of Java – A great way to meet people and learn new things. Obtain the Oracle Certified Web Developer Certification – I got the SCJP a few years ago and would like to obtain another one.  One step closer to Certified Enterprise Architect. Learn scala – As a language geek, I like to stick to the Pragmatic Programmer’s ‘learn a new language every year’ rule (last year was Ruby).  Scala presents some new concepts all wrapped in a JVM-based OOP language.  Time to dig in. Write an app using JSF – New JEE 6 features are pretty slick.  I want to really leverage them in an app. Present at a user group meeting – Last but not least, I would like to improve my public speaking and skills in presenting.  Also, is a great reason to dig in to some latest and greatest tech. Use git more, and more effectively – Trying to move all my personal projects from Subversion to Git. That’s it.  A little daunting, but I am confident I can at least touch on most of these and it’s a great roadmap to my professional development.

  • IPS Package Groups

    - by Alan_Solaris_RE
    IPS group packages consist solely of dependencies on other packages that make up a logical grouping of software. These are similar to, but not the equivalent of, Solaris 10 metaclusters. The main difference is that metaclusters are nested subsets ranging from a minimal install to nearly all packages on the media. Group packages have no such hierarchy. They can overlap other groups, or be completely disjoint sets. A group dependency is set this way in an IPS package manifest file: depend fmri=full/pkg/name type=group Current Solaris Groups Solaris currently has 4 system groups defined. These are used for different types of installation, and are included in the xml manifest files used by the various Solaris installers: Package Name Summary Description Default Installation For:  group/system/solaris-desktop Oracle Solaris Desktop Provides an Oracle Solaris desktop environment Live Media  group/system/solaris-large-server Oracle Solaris Large Server Provides an Oracle Solaris large server environment Text Installer  group/system/solaris-small-server Oracle Solaris Small Server Provides a useful command-line Oracle Solaris environment  Zones  group/system/solaris-auto-install  Oracle Solaris Automated Installer Client  Provides an Oracle Solaris Automated Installer client  Automated Installer There are also several "feature" groups such as AMP and GNU Developer Tools. These are provided for convenience, but are not used directly by any installers. Retrieving Group Package Information A listing of all current groups can be found with the command: pkg info -r group/* A listing of all the packages in a group can be obtained with: pkg contents -o fmri -H -rt depend -a type=group groupname An example: $ pkg contents -o fmri -H -rt depend -a type=group solaris-desktop archiver/gnu-tar audio/audio-utilities codec/flac codec/libtheora codec/ogg-vorbis codec/speex communication/im/pidgin etc. You can determine which package group is currently installed on your system: $ pkg list group/system/\* Output would look like: NAME (PUBLISHER) VERSION IFO group/system/solaris-desktop 0.5.11-0.175.0.0.0.0.0 i-- Note that there are not version numbers associated with a group package dependency. The package version that best fits the system will be used, based on other dependencies such as what is listed in incorporation files. Installing a Group To Install a group, simple use the group package name as you would any other package: $ pkg install solaris-small-server  If you want to exclude a package from installing, you can use the --reject flag: $ pkg install --reject audio/audio-utilities solaris-desktop Creating Your Own Group To create your own group package, you can follow the pkg(5) documentation on how to create a package, and use this action for each package that is part of your group:   depend fmri=full/pkg/name type=group

  • Part 5: Choose the right tool - or - why

    - by volker.eckardt(at)oracle.com
    Consider the following client request “Please create a report for us to list expenses”. Which Oracle EBS tool would you choose? There are plenty of options available: Oracle Reports, or BI Publisher with PDF or Excel layout, or Discoverer, or BI Publisher Stand Alone, or PDF online generation, or Oracle WebADI, or Plain SQL*Plus as Concurrent Program, or Online review option … Assuming, you as development lead have to decide, you may decide by available skill set in your development team. However, is this a good decision? An important question to influence the decision is the “Why” question: why do you need this report, what process is behind, what exactly you like to achieve? We see often data created or printed, although it would be much better to get the data in Excel, and upload changes via WebADI directly. There are more points that should drive your decision: How many of such requirements you have got? Has this technique been used in the project already? Are there related reusable’s you may gain from? How difficult is it to maintain your solution? Can you merge this report with another one, to reduce test and maintenance work? In addition, also your own development standards should guide you a bit to come to a good decision. In one of my own projects, we discussed such topics in our weekly team meeting. By utilizing the team knowledge best, you may come to a better decision, and additionally, your team supports your decision. Unfortunately, I have rarely seen dedicated team trainings or planned knowledge transfer to support such processes. Often the pressure to deliver on time is too high to have discussion and decision time left. But exactly this can help keeping maintenance costs low by limiting the number of alternative solutions for similar requirements. Lastly, design decisions should be documented to allow another person taking this over easily. Decisions shall be reviewed and updated regularly, to reflect related procedures or Oracle products respective product versions. Summary: Oracle EBS offers plenty of alternatives to implement customizations. Create and maintain a decision tree to support the design process. Do not leave the decision just on developer side. Limit the number of alternative solutions as best as possible; choose one which is the most appropriate also from future maintenance perspective.

  • Why can't the IT industry deliver large, faultless projects quickly as in other industries?

    - by MainMa
    After watching National Geographic's MegaStructures series, I was surprised how fast large projects are completed. Once the preliminary work (design, specifications, etc.) is done on paper, the realization itself of huge projects take just a few years or sometimes a few months. For example, Airbus A380 "formally launched on Dec. 19, 2000", and "in the Early March, 2005", the aircraft was already tested. The same goes for huge oil tankers, skyscrapers, etc. Comparing this to the delays in software industry, I can't help wondering why most IT projects are so slow, or more precisely, why they cannot be as fast and faultless, at the same scale, given enough people? Projects such as the Airbus A380 present both: Major unforeseen risks: while this is not the first aircraft built, it still pushes the limits if the technology and things which worked well for smaller airliners may not work for the larger one due to physical constraints; in the same way, new technologies are used which were not used yet, because for example they were not available in 1969 when Boeing 747 was done. Risks related to human resources and management in general: people quitting in the middle of the project, inability to reach a person because she's on vacation, ordinary human errors, etc. With those risks, people still achieve projects like those large airliners in a very short period of time, and despite the delivery delays, those projects are still hugely successful and of a high quality. When it comes to software development, the projects are hardly as large and complicated as an airliner (both technically and in terms of management), and have slightly less unforeseen risks from the real world. Still, most IT projects are slow and late, and adding more developers to the project is not a solution (going from a team of ten developer to two thousand will sometimes allow to deliver the project faster, sometimes not, and sometimes will only harm the project and increase the risk of not finishing it at all). Those which are still delivered may often contain a lot of bugs, requiring consecutive service packs and regular updates (imagine "installing updates" on every Airbus A380 twice per week to patch the bugs in the original product and prevent the aircraft from crashing). How can such differences be explained? Is it due exclusively to the fact that software development industry is too young to be able to manage thousands of people on a single project in order to deliver large scale, nearly faultless products very fast?

  • How to be successful at BDD Specifications Workshops?

    - by sigo
    Today we tried to introduce BDD in our software development process by having a specification workshop. For this workshop we had 2 developers, 1 tester and 1 business analyst. The workshop lasted 1h30 and by the end of it we managed to figure out some BDD scenarios for our new feature. We tried to focus on finding the scenarios that we could miss, and the difficult ones. At the end of the workshop some people were actually unhappy with the workshop. One developer felt he wasted his time as he was used to be given out the scenarios directly by the business analyst and review them with her. The business analyst didn't feel confident with our scenario coverage (Had a feeling that we could have missed out other important stuff) but more importantly felt that this workshop was also a waste of time as she could have figured out all these scenarios by herself and in a shorter period of time. So my question is how that kind of workshop can actually work. In the theory, given you have a new feature to develop, you put the tree 'amigos' (dev/tester/ba) in the same room so that they can collaborate together on writing the differents requirements for the new feature using examples. I can see all the benefits from that. Specially in term of knowledge sharing and common product/end goal/done vision. But in practice, we still think it is more cost effective to first have a BA to work on his own on the examples and only then to have the scenarios to be reviewed/reworked by the 3 'amigos'. By having the BA to work on his own, we actually feel more confident that we are less going to miss out stuff + we still get to review the scenarios afterward to double check. We don't think than simple brainstorming/deliberate discovery is actually enought to seriously cover all the requirement for a feature. The business analyst is actually the best person for that kind of stuff. The thing we just do is to review what she wrote and see if then we have a common understanding (which could then lead to rewrite some of her scenarios or add new ones she could have missed). This workshop lasted 1h30, and by the end of it, we didn't feel confident enought about wha we did...sure we could have spent more time on it but honestly most people get exhausted after 1h30 of brainstorming. So how can you get that to work effectively in practice ?

  • How to appear very professional on my first freelance project?

    - by iamserious
    I need some help on appearing very professional on my first freelance project. How / What should you do to achieve this? Background: I started as a full time web developer 18 months ago, two promotions later I am now a senior software engineer. I've never had any problems with designing / developing / coding a complicated system. I thought I could use some help for Christmas and I started bidding for a project and now I have one - from a very reputable lawyers association in London. I have no problem dealing with the actual implementation of the system, but I have no idea how to appear professional throughout the whole process. About the project: This lawyers association are starting a distant training courses and in addition to having a website to show off all their clients etc, they want a students area where their students would log in, download course materials allocated to them etc.. and an admin section where they assign courses to students / create new ones / upload materials etc.. Questions breakdown: 1) How should I start with the requirement gathering? Is using scrum a good idea, or should I use something like Volere Template - and what should I do with it? should I submit a copy to the client etc.. 2) How often should I meet the client? Would once a fortnight would be good? 3) What are the processes / protocols that I need to follow so that they would be satisfied with me and think that I am very professional 4) How much should I charge for the product? 5) How should I get a quote / contract / receipt for the whole project? 6) What are the steps that professional freelancers go through, during the life cycle of a project? My Research so far Looking at How much should I charge doesn't help.. I live in London, zone 1, though I have no idea how much a project of this size would cost. Help on this would be appreciated. How to be professional articles talks about the work / time management etc and not the actual process, what would real people do etc.. it's like academia theory, but not practical. If this needs revising, please let me know, do not close it because of whatever reason, I will edit the question or details to fit the needs. Thanks for reading a lengthy question.

  • Data Source Use of Oracle Edition Based Redefinition (EBR)

    - by Steve Felts
    Edition-based redefinition is a new feature in the 11gR2 release of the Oracle database. It enables you to upgrade the database component of an application while it is in use, thereby minimizing or eliminating down time. It works by allowing for a pre-upgrade and post-upgrade view of the data to exist at the same time, providing a hot upgrade capability. You can then specify which view you want for a particular session.  See the Oracle Database Advanced Application Developer's Guide for further information. There is also a good white paper at Edition Based Definition. Using this feature of the Oracle database does not require any new WebLogic Server functionality. It is set for each connection in the pool automatically by simply specifying SQL ALTER SESSION SET EDITION = edition_name in the Init SQL parameter in the data source configuration. This can be configured either via the console or via WLST (setInitSQL on the JDBCConnectionPoolParams). This SQL statement is executed for each newly created physical database connection.Note that we are assuming that a data source references only one edition of the database. To make use of this feature, you would have an earlier version of the application with a data source that references the earlier EDITION and a later version of the application with a data source that references the later EDITION.   Once you start talking about multiple versions of a WLS application, you should be using the WLS "side-by-side" or "versioned" deployment feature.  See Developing Applications for Production Redeployment for more information.  By combining Oracle database EBR and WLS versioned deployment, the application can be failed over with no downtime, making the combination of features more powerful than either independently. There is a catch - you need to be running with a versioned database and a versioned application initially so then you can switch versions.  The recommended way to version a WLS application is to simply add the "Weblogic-Application-Version" property in the MANIFEST.MF file(you can also specify it at deployment time). The recommended way to configure the data source is to use a packaged data source descriptor that's stored in the ear or war so that everything is self-contained.  There are some restrictions.  You can't use a packaged data source with Logging Last Resource (LLR) - you need to use a system resource.  You can't use an application-scoped packaged data source with EmulateTwoPhaseCommit for the global-transactions-protocol with a versioned application - use a global scope.  See Configuring JDBC Application Modules for Deployment for more details. There's one known problem - it doesn't work correctly with an XA data source (patch available with bug 14075837).

  • Capture a Query Executed By An Application Or User Against a SQL Server Database in Less Than a Minute

    - by Compudicted
    At times a Database Administrator, or even a developer is required to wear a spy’s hat. This necessity oftentimes is dictated by a need to take a glimpse into a black-box application for reasons varying from a performance issue to an unauthorized access to data or resources, or as in my most recent case, a closed source custom application that was abandoned by a deserted contractor without source code. It may not be news or unknown to most IT people that SQL Server has always provided means of back-door access to everything connecting to its database. This indispensible tool is SQL Server Profiler. This “gem” is always quietly sitting in the Start – Programs – SQL Server <product version> – Performance Tools folder (yes, it is for performance analysis mostly, but not limited to) ready to help you! So, to the action, let’s start it up. Once ready click on the File – New Trace button, or using Ctrl-N with your keyboard. The standard connection dialog you have seen in SSMS comes up where you connect the standard way: One side note here, you will be able to connect only if your account belongs to the sysadmin or alter trace fixed server role. Upon a successful connection you must be able to see this initial dialog: At this stage I will give a hint: you will have a wide variety of predefined templates: But to shorten your time to results you would need to opt for using the TSQL_Grouped template. Now you need to set it up. In some cases, you will know the principal’s login name (account) that needs to be monitored in advance, and in some (like in mine), you will not. But it is VERY helpful to monitor just a particular account to minimize the amount of results returned. So if you know it you can already go to the Event Section tab, then click the Column Filters button which would bring a dialog below where you key in the account being monitored without any mask (or whildcard):  If you do not know the principal name then you will need to poke around and look around for things like a config file where (typically!) the connection string is fully exposed. That was the case in my situation, an application had an app.config (XML) file with the connection string in it not encrypted: This made my endeavor very easy. So after I entered the account to monitor I clicked on Run button and also started my black-box application. Voilà, in a under a minute of time I had the SQL statement captured:

  • Understanding exceptional cases

    - by Justin
    I've been studying the use of exceptions in various php projects (such as Doctrine and Zend Framework). Exceptions seem to be thrown when unordinary input/state occurs. A perfect example is Doctrine throwing an exception when you try to use a invalid query string. I think the creators of the doctrine api understood that first, you can't query data by using an invalid DQL statement, and a developer should immediately be warned that an error has occurred, rather then letting execution continue with the possibility of an error code going un-checked. I also bet that this simplifies reading the code. I can't think of a situation where you would want to use an invalid DQL statement, except unit testing. Since this is true, it's better to avoid plaguing a bunch of code with null/error checks and use exceptions. I've read in books that exceptions shouldn't be thrown when validating dating user input. I've seen examples where of where the guideline is broken. One example is the Zend framework. If supplying an invalid controller or action name, an exception is thrown. Unlike doctrine, the user has more direct control over this sort of input. I know you can configure an error controller and set up a 404 message or what have you, but I'm curious why they have used an exception in this scenario? I guess you can argue the Zend Framework does not know how to continue processing the quest. One last example Is I wrote a function to return some html based on a given resource type. This resource type is hard-coded and sent when a user interacts with a web site (such as clicking a button to display the form to input data). I don't expect users to be mucking around with the request type. Under normal operating conditions, the resource type should be valid. To clean up some logic, I was going to throw an exception if a particular form wasn't found. This is mainly to find the correct form associated with a resource type so proper validation can occur. Does this sound like a valid use case for an exception? Right now it's pretty trivial, but I do plan to implement a restful consumer and re-using a function to map resources to their validation services would be very useful. I can then catch the exception and based on the consumer, return an error message suitable for the request type...

  • Understanding the SQL Server 2008 R2 Installation Center

    - by Enrique Lima
    What is available to us through those links?  Have you taken the time to explore and identify what could be useful to you? One of many gems that has come to my attention is the possibility of provisioning SQL Server to work in an image based environment (hint: Virtualization Template perhaps?!?).   Planning: Includes requirements information, documentation, how to guides, online documentation installation and other tools. Among the other tools you will find the System Configuration checker and The Upgrade Advisor. Both tools very important to ensure your deployment and installation would be successful.     Installation:  This sections focuses on getting installations going, from standalone to cluster when it comes to new instances.  Add new nodes to an existing cluster, and also perform upgrades (in this case to SQL Server 2008 R2).  Also part of this is the option to find updates available.   Maintenance: We find in this section, options that will assist us in tasks like repairing corrupt installations to removing nodes from a cluster. An option that is interesting (and we should discuss benefits later in another post) is to be able to do an Edition Upgrade, this is a feature expansion and addition based on your product installation (Developer to Enterprise, for example)   Tools:  From the System Configuration Checker to identify readiness for deployment in a successful manner, to being able to report on features installed.  And being able to run upgrades of existing packages developed in the 2005 offering to the 2008 R2 release for SSIS.   Resources: Useful and essential links to gather information and guidance.   Advanced: Here is where it gets interesting.  I break this down into 3 main groups: Installation Automation: When you install SQL Server there is a configuration file that gets dropped (ConfigurationFile.ini) that would allow for you to perform automated installations.  There are switches and options that go with this to have that process working. Cluster configuration for Sysprep: Create images that are cluster ready, 2 options, start the prep work, and then the complete once at the final destination. Stand-alone configuration for Sysprep:  Like the clustering counterpart, 2 options, prep and complete.  Giving you the option to create standard templates for your SQL Server deployments. I find it fitting that the 3 topics listed here should (and will) be additional topics I will discuss.   Options: Very clear and specific about what this means. Select the Processor Type or the Installation Media Root Path.

  • Understanding the levels of computing

    - by RParadox
    Sorry, for my confused question. I'm looking for some pointers. Up to now I have been working mostly with Java and Python on the application layer and I have only a vague understanding of operating systems and hardware. I want to understand much more about the lower levels of computing, but it gets really overwhelming somehow. At university I took a class about microprogramming, i.e. how processors get hard-wired to implement the ASM codes. Up to now I always thought I wouldn't get more done if learned more about the "low level". One question I have is: how is it even possible that hardware gets hidden almost completely from the developer? Is it accurate to say that the operating system is a software layer for the hardware? One small example: in programming I have never come across the need to understand what L2 or L3 Cache is. For the typical business application environment one almost never needs to understand assembler and the lower levels of computing, because nowadays there is a technology stack for almost anything. I guess the whole point of these lower levels is to provide an interface to higher levels. On the other hand I wonder how much influence the lower levels can have, for example this whole graphics computing thing. So, on the other hand, there is this theoretical computer science branch, which works on abstract computing models. However, I also rarely encountered situations, where I found it helpful thinking in the categories of complexity models, proof verification, etc. I sort of know, that there is a complexity class called NP, and that they are kind of impossible to solve for a big number of N. What I'm missing is a reference for a framework to think about these things. It seems to me, that there all kinds of different camps, who rarely interact. The last few weeks I have been reading about security issues. Here somehow, much of the different layers come together. Attacks and exploits almost always occur on the lower level, so in this case it is necessary to learn about the details of the OSI layers, the inner workings of an OS, etc.

  • How can I tweak this A* search pathfinding algorithm to handle different terrain movement values?

    - by user422318
    I'm creating a 2D map-based action game with similar interaction design as Diablo II. In other words, the player clicks around a map to move their player. I just finished player movement and am moving on to pathfinding. In the game, enemies should charge the player's character. There are also five different terrain types that give different movement bonuses. I want the AI to take advantage of these terrain bonuses as they try to reach the player. I was told to check out the A* search algorithm (http://en.wikipedia.org/wiki/A*_search_algorithm). I'm doing this game in HTML5 and JavaScript, and found a version in JavaScript: http://www.briangrinstead.com/blog/astar-search-algorithm-in-javascript I'm trying to figure out how to tweak it though. Below are my ideas about what I need to change. What else do I need to worry about? When I create a graph, I will need to initialize the 2D array I pass in passed on with a traversal of a map that corresponds to the different terrain types. in graph.js: "GraphNodeType" definition needs to be modified to handle the 5 terrain types. There will be no walls. in astar.js: The g and h scoring will need to be modified. How should I do this? in astar.js: isWall() should probably be removed. My game doesn't have walls. in astar.js: I'm not sure what this is. I think it indicates a node that isn't valid to be processed. When would this happen, though? At a high level, how do I change this algorithm from "oh, is there a wall there?" to "will this terrain get me to the player faster than the terrain around me?" Because of time, I'm also debating reusing my Bresenham algorithm for the enemies. Unfortunately, the different terrain movement bonuses won't be used by the AI, which will make the game suck. :/ I'd really like to have this in for the prototype, but I'm not a developer by trade nor am I a computer scientist. :D If you know of any code that does what I'm looking for, please share! Sanity check tips for this are also appreciated.

  • Forced to be trained [closed]

    - by steeb
    is it OK to force employees to take a training in order to make them sign a contract to stay in the job for X years? Here I'm the only developer in the company and before this job I've developed in VB6, VB.Net and others. There are others technicians here but they query the database server to make reports and make little programs but do not spend all day in programming. I was hired here to manage some legacy data to be migrated to a new system and I used my experience to accomplish the task. I also have made some utilities and other developments. Since we went live with the new system I've been developing a lot of side programs, add-ons and changed the source code of it and basically I've been learning from it since then and became some sort of jack of all trades when some feature needs to be changed or corrected. I have one and a half year in this company but during the last 8 months I've been entirely programming in the system. There have been times when even the implementers ask me how I accomplish certain things. The issue here is that the company has come and told me and other co-workers (which do not program in the system but know basic programming and databases) to have a basic training to program for the new system's platform and when we finish it we will sign a contract to stay in the company for an unspecified time. They have offered also an unspecified better salary. I'm feeling very suspicious cause I know the basics of system and I don't understand why I have to take it, being known by everybody all developments I've made. I gathered with my boss and told him that I should not take that course because I feel that I can learn more with all the daily requirements I've been asked and they should save that money. But he responded me that I have to take it and sign after that. I think they want me to be with them for a long time, and I'd like to, but my opinion is that I would like to stay in the company because I feel comfortable in all laboral aspects (including salary) but not because I signed a contract forced to do more tasks and forced to say no if I have others and better job offers. What advice can you give me in this kind of situation?
