  • Is there any kind of established architecture for browser based MMO games?

    - by black_puppydog
    I am beginning the development of a broser based game in which players take certain actions at any point in time. Big parts of gameplay will be happening in real life and just have to be entered into the system. I believe a good kind of comparison might be a platform for managing fantasy football, although I have virtually no experience playing that, so please correct me if I am mistaken here. The point is that some events happen in the program (i.e. on the server, out of reach for the players) like pulling new results from some datasource, starting of a new round by a game master and such. Other events happen in real life (two players closing a deal on the transfer of some team member or whatnot - again: have never played fantasy football) and have to be entered into the system. The first part is pretty easy since the game masters will be "staff" and thus can be trusted to a certain degree to not mess with the system. But the second part bothers me quite a lot, especially since the actions may involve multiple steps and interactions with different players, like registering a deal with the system that then has to be approved by the other party or denied and passed on to a game master to decide. I would of course like to separate the game logic as far as possible from the presentation and basic form validation but am unsure how to do this in a clean fashion. Of course I could (and will) put some effort into making my own architectural decisions and prototype different ideas. But I am bound to make some stupid mistakes at some point, so I would like to avoid some of that by getting a little "book smart" beforehand. So the question is: Is there any kind of architectural works that I can read up on? Papers, blogs, maybe design documents or even source code? Writing this down this seems more like a business application with business rules, workflows and such... Any good entry points for that?

  • Dynamic Monitoring Service (DMS) Configuration Dumping and CPU Utilization

    - by ShawnBailey
    There was recently a report of CPU spikes on a system that were occuring at precise 3 hour intervals. Research revealed that the spikes were the result of the Dynamic Monitoring Service generating a metrics dump and writing it under the server 'logs' folder for every WLS server in the domain. This blog provides some information on what this is for and how to control it. The Dynamic Monitoring Service is a facility in FMw (JRF to be more precise) that collects runtime data on the components deployed to WebLogic. Each component is responsible for how much or how little they use the service and SOA collects a fair amount of information. To view what is collected on any running server you can use the following URL, http://host:port/dms/Spy and login with admin credentials. DMS is essentially always running and collecting this information in the runtime and to protect against loss of this data it also runs automatic backups, by default at the 3 hour interval mentioned above. Most of the management options for DMS are exposed through WLST but these settings are not so we must open the dms_config.xml file which can be found in DOMAIN_HOME/config/fmwconfig/servers/<server_name>/dms_config.xml. The contents are fairly short and at the bottom you will find the following entry: <dumpConfiguration>     <dump intervalSeconds="10800" maxSizeMBytes="75" enabled="true"/> </dumpConfiguration> The interval of 10800 seconds corresponds to the 3 hours and the maximum size is 75MB. The file is written as an archive to DOMAIN_HOME/servers/<server_name>/logs/metrics. This archive contains the dump in XML format. You can disable the dumps all together by simply setting the 'enabled' value to 'false' or of course you could modify the other parameters to suit your needs. Disabling the dumps will NOT impact DMS collections or display at runtime. It will only eliminate these periodic backups.

  • Using onboard and pci-e graphics card at the same time

    - by Endle
    Hello wonderful people. I know there are several other posts with similar questions. I also know how to use Google. I also have read up on posts discussing bumblebee, crossfire, ati catylist and many other interesting topics. I would just like someone to give me advice on how to use the onboard and pci-e graphics at the same time. I know the computer is capable of doing this. It works in Windows. I can use the VGA and DVI onboard port and the HDMI port of the add on card all at the same time. Works great in Windows 7, In Ubuntu, it seems only one or the other will work. I can use any combination of two displays on either adapter: VGA and HDMI..HDMI and DVI..so forth and so on. I have started experimenting with xorg.conf files, but have not been able to get any of them to work. Here is my last attempt at writing an xorg.conf file: Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" LeftOf "Screen1" InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Device" Identifier "Onboard Video" Driver "radeon" BusID "PCI:01:05.0" EndSection Section "Device" Identifier "Graphics Card" Driver "radeon" BusID "PCI:02:00.0" EndSection Section "Monitor" Identifier "CRT2" Option "VendorName" "ViewSonic" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "DVI1" VendorName "ACR" ModelName "P224W" Option "DPMS" EndSection Section "Monitor" Identifier "DVI2" Option "VendorName" "Acer" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Screen" Identifier "Screen0" Device "Onboard Video" Monitor "CRT2" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x1024" EndSubSection EndSection Section "Screen" Identifier "Screen1" Device "Graphics Card" Monitor "DVI1" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1920x1080" EndSubSection

  • tips, guidelines, points to remember for rendering professional code?

    - by ronnieaka
    I'm talking about giving clients professional looking code. The whole nine yards, everything you hardcore professional highly experienced programmers here probably do when coding freelance or for the company you work in. I'm fresh out of college and I'm going into freelance. I just want to be sure that my first few projects leave a good after-taste of professionalism imprinted on the clients' minds. When I Googled what i'm asking here, I was given pages that showed various websites and tools that let you make flashy websites and templates etc. The $N package and such stuff. I can't recall the word experts use for it. Standard, framework [i know that's not it]. English isn't my first language so I'm sorry I don't really don't know the exact phrase for it. That abstract way of writing code so that you don't come across as a sloppy programmer. That above mentioned way for programming websites and desktop software [in python/C/C++/Java]. EDIT: i can work on the accruing vast knowledge and know-how and logic building etc. what i'm asking for is the programming standard/guidelines you guys follow so that the client on seeing code feels that its a professional solution. Like comment blocks, a particular indentation style something like that. Is there any book on it or specific list of points for enterprise type coding by them? Especially here as in my case, for building websites [php for now..], and desktop software [c/c++/java/python]

  • Approach to Authenticate Clients to TCP Server

    - by dab
    I'm writing a Server/Client application where clients will connect to the server. What I want to do, is make sure that the client connecting to the server is actually using my protocol and I can "trust" the data being sent from the client to the server. What I thought about doing is creating a sort of hash on the client's machine that follows a particular algorithm. What I did in a previous version was took their IP address, the client version, and a few other attributes of the client and sent it as a calculated hash to the server, who then took their IP, and the version of the protocol the client claimed to be using, and calculated that number to see if they matched. This works ok until you get clients that connect from within a router environment where their internal IP is different from their external IP. My fix for this was to pass the client's internal IP used to calculate this hash with the authentication protocol. My fear is this approach is not secure enough. Since I'm passing the data used to create the "auth hash". Here's an example of what I'm talking about: Client IP: 192.168.1.10, Version: 2.4.5.2 hash = 2*4*5*1 * (1+9+2) * (1+6+8) * (1) * (1+0) Client Connects to Server client sends: auth hash ip version Server calculates that info, and accepts or denies the hash. Before I go and come up with another algorithm to prove a client can provide data a server (or use this existing algorithm), I was wondering if there are any existing, proven, and secure systems out there for generating a hash that both sides can generate with general knowledge. The server won't know about the client until the very first connection is established. The protocol's intent is to manage a network of clients who will be contributing data to the server periodically. New clients will be added simply by connecting the client to the server and "registering" with the server. So a client connects to the server for the first time, and registers their info (mac address or some other kind of unique computer identifier), then when they connect again, the server will recognize that client as a previous person and associate them with their data in the database.

  • Should I be learning Linq, Direct SQL Commands (in .net), EF or other?

    - by Wil
    Basically, I have a very good knowledge of plain old SQL coming from Classic ASP programming. Over the past couple of months, I have been learning C# and today was my first full day at MVC 3 (Razor) which I am loving! I need to get back in to Databases and I know that writing SqlCommand everywhere is obviously outdated (although it is nice I can still do it!). I used to go to a great usergroup as an IT Pro and the developer stuff went completely over my head, however I do remember a few things which kept coming up such as LINQ... However, that was some time ago and now the same people on Twitter are saying how out dated it is. I have tried to do research on both and I am clueless as to what direction I should go in, or when to use one over another (if learning both is a good thing). I am more so confused as I thought EF was a part of the .Net Framework, however, reading through the quick start guide, I had to download a component using Nuget. ... Basically I am out of my depth here and just need some honest advice of where to go!

  • How can I go about learning to write a shader

    - by Donutz
    So here's the background: I'm writing a game, just for my own amusement and education really. I've already come to the conclusion that XNA was the way to go for graphics, I've bought a couple of books, I've gotten basic game graphics going, and that's great. Now I'm starting to get a little in-depth and I'm starting to need to do stuff not covered in my (beginner) books. In particular, I need to display a sprite using a mask. Actually, what I need to do is display a generic sprite with a different color for each player. After banging around on the web, it seems the way to go is to have a color texture (one for each player) which I display using the mask, then display the generic part of the sprite. This has to be done dynamically, i.e. at runtime because there are too many sprites to keep in memory if I try to generate all the permutations at startup. So, I need to use a shader. Fine. I've downloaded a sample shader program, and managed to hit it with a hammer until it does something close enough to what I want so that I know I'm on the right track. And here, we come to my problem... I have no friggin' clue what I'm doing. While there are a lot of samples and such about shaders, no one ever actually explains what's going on. For instance, I can't find any real docs on Tex2D. I feel like the guys in Zoolander poking at the computer. So, my question (yes, I have a question) -- where is a good URL or what is a good book to take me from dumskie to reasonably competent to write a basic shader?

  • Access Control Service: Walkthrough Videos of Web Application, SOAP, REST and Silverlight Integration

    - by Your DisplayName here!
    Over the weekend I worked a little more on my ACS2 sample. Instead of writing it all down, I decided to quickly record four short videos that cover the relevant features and code. Have fun ;) Part 1 – Overview This video does a quick walkthrough of the solution and shows the web application part. This includes driving the sign in UI via JavaScript (thanks Matias) as well as the registration logic I wrote about here. watch Part 2 – SOAP Service and Client The sample app also exposes a WCF SOAP service. This video shows how to wire up the service to ACS and hows how to create a client that first requests a token from an IdP and then sends this token to ACS. watch Part 3 – REST Service and Client This part shows how to set up a WCF REST service that consumes SWT tokens from ACS. Unfortunately there is currently no standard WIF plumbing for REST. For the service integration I had to combine a lot of code from different sources (kzu, zulfiq) as well as the WIF SDK and OAuth CTPs together. But it is working. watch Part 4 – Silverlight and Web Identity Integration This part took by far the most time to write. The Silverlight Client shows ho to sign in to the application using a registered identity provider (including web identities) and using the resulting SWT token to call our REST service. This is designed to be a desktop (OOB) client application (thanks to Jörg for the UI magic). watch code download

  • Keyboard not working 100% after Ubuntu 13.10 upgrade

    - by Marky
    If this has already been asked, my apologies, I did not find it before writing this. So please do point me to the correct page. Anyway, I have this weird issue on my laptop right now. The keyboard is not functioning 100%. This means, I can type my login details to get into Ubuntu. I can type something on Dash. But other than this (on the desktop), no output from the keyboard when using all the other apps - as in I start to type and nothing comes out. The surprising thing is that when I shift to Guest session, the keyboard functions normally. When I shift to another TTY, like Alt+F5, keyboard works normally. This is the first time I've encountered this so far in my use of Linux. Keyboards normally never fail on any of the desktop environments I've used over the years. Any ideas what's happening? Could be the config files on my home is too messy already. I've upgraded this from 11.10 to 13.04, then now 13.10 without a re-install. Works fine so far, until now that I can't do much without a keyboard. Thanks in advance! P.S. Mouse and touchpad works fine.

  • Interface (contract), Generics (universality), and extension methods (ease of use). Is it a right design?

    - by Saeed Neamati
    I'm trying to design a simple conversion framework based on these requirements: All developers should follow a predefined set of rules to convert from the source entity to the target entity Some overall policies should be able to be applied in a central place, without interference with developers' code Both the creation of converters and usage of converter classes should be easy To solve these problems in C# language, A thought came to my mind. I'm writing it here, though it doesn't compile at all. But let's assume that C# compiles this code: I'll create a generic interface called IConverter public interface IConverter<TSource, TTarget> where TSource : class, new() where TTarget : class, new() { TTarget Convert(TSource source); List<TTarget> Convert(List<TSource> sourceItems); } Developers would implement this interface to create converters. For example: public class PhoneToCommunicationChannelConverter : IConverter<Phone, CommunicationChannle> { public CommunicationChannel Convert(Phone phone) { // conversion logic } public List<CommunicationChannel> Convert(List<Phone> phones) { // conversion logic } } And to make the usage of this conversion class easier, imagine that we add static and this keywords to methods to turn them into Extension Methods, and use them this way: List<Phone> phones = GetPhones(); List<CommunicationChannel> channels = phones.Convert(); However, this doesn't even compile. With those requirements, I can think of some other designs, but they each lack an aspect. Either the implementation would become more difficult or chaotic and out of control, or the usage would become truly hard. Is this design right at all? What alternatives I might have to achieve those requirements?

  • Getting into the details of game engine programming

    - by Darkslash
    I am interested in learning game programming, but I really have an interest in the lower level engineering in games. I have OpenGL experience, and I am really interested in learning more about implementing AI, Physics, etc. I have a computer science degree, so I really like getting into technical stuff. Many times when I ask about this sort of thing, I get a lot of "Use an engine", "Use Unity3d", "Why waste your time writing code that already exists", etc, etc. My idea was to use simpler libraries such as SFML or XNA so that I could learn how to implement the more complex systems. The thing is, although I do want to write games, I want to learn things that using something like Unity simply doesn't teach you. My goal is not to make a current generation quality 3D game to sell, I just want to make some cool smaller games and learn all I can about the programming side of game development. Is this something that people just do not do anymore? It seems like everywhere I turn people are using Unity or UDK or GameMaker. I fully understand why you would use a tool like these, but I cant see how they would suit my purposes. So where does someone like myself turn? Am I trying to learn something that people just do not bother doing anymore? Is the innovation in this area gone and just all about gameplay now? I'm sorry if this question seems silly, but I am genuinely interested in knowing more about this and meeting more people who are interested in this sort of thing.

  • Most common parts of a SELECT SQL query?

    - by jnrbsn
    I'm writing a function that generates a SELECT SQL query. (I'm not looking for a tool that already does this.) My function currently takes the following arguments which correspond to different parts of the SELECT query (the base table name is already known): where order fields joins group limit All of these arguments will be optional so that the function generates something like this by default: SELECT * FROM `table_name` I want to order the arguments so that the most often used parts of a SELECT query are first. That way the average call to the function will use as few of the arguments as possible rather than passing a null value or something like that to skip an argument. For example, if someone wanted to use the 1st and 3rd arguments but not the rest, they might have to pass a null value as the 2nd argument in order to skip it. So, for general purpose use, how should I order the arguments? Edit: To be more precise, out of the query parts I listed above, what is the order from most used to least used? Also, I'm not looking for solutions that allow me to not have to specify the order. Edit #2: The "fields" argument will default to "*" (i.e all fields/columns).

  • Javascript Module pattern with DOM ready

    - by dego89
    I am writing a JS Module pattern to test out code and help me understand the pattern, using a JS Fiddle. What I can't figure out is why my "private methods" on line 25 and 26, when referenced via DOM ready, have a value of undefined. JSFiddle Code Sample: var obj = { key: "value" }; var Module = (function () { var innerVar = "5"; console.log("obj var in Module:"); console.log(obj); function privateFunction() { console.log("privateFunction() called."); innerFunction(); function innerFunction() { console.log("inner function of (private function) called."); } } function _numTwo() { console.log("_numTwo() function called."); } return { test: privateFunction, numTwo: _numTwo } }(obj)); $(document).ready(function () { console.log("$ Dom Ready"); console.log("Module in Dom Ready: "); console.log(Module.test()); });

  • Should a software developer get a yearly equipment budget?

    - by CrazyDart
    I am looking at a new position with a new company. I have talked to some people in the past (in general, not at this company) that they had been given a yearly budget to buy new computer stuff to keep up to date. Now why I feel this question is worth asking here is that Joel comes right out and says an employer should pay for the best equipment money can buy... within reason of course. From The Joel Test: 12 Steps to Better Code 9. Do you use the best tools money can buy? Writing code in a compiled language is one of the last things that still can't be done instantly on a garden variety home computer... Top notch development teams don't torture their programmers. Even minor frustrations caused by using underpowered tools add up, making programmers grumpy and unhappy. And a grumpy programmer is an unproductive programmer... Does anyone know if the industry has such a standard to offer an allowance or budget? I have never worked for a company like this, but I am thinking I should toss this in the ring for negotiations. Seems reasonable. How do bigger companies like MS, Google, and Apple handle this? If you say yes, give a range... I have been told numbers from $5k to $10k. Seems high to me, but hey I would gladly take it.

  • How can I reduce the amount of time it takes to fully regression test an application ready for release?

    - by DrLazer
    An app I work on is being developed with a modified version of scrum. If you are not familiar with scrum, it's just an alternative approach to a more traditional watefall model, where a series of features are worked on for a set amount of time known as a sprint. The app is written in C# and makes use of WPF. We use Visual C# 2010 Express edition as an IDE. If we work on a sprint and add in a few new features, but do not plan to release until a further sprint is complete, then regression testing is not an issue as such. We just test the new features and give the app a good once over. However, if a release is planned that our customers can download - a full regression test is factored in. In the past this wasn't a big deal, it took 3 or 4 days and the devs simply fix up any bugs found in the regression phase, but now, as the app is getting larger and larger and incorporating more and more features, the regression is spanning out for weeks. I am interested in any methods that people know of or use that can decrease this time. At the moment the only ideas I have are to either start writing Unit Tests, which I have never fully tried out in a commercial environment, or to research the possibilty of any UI Automation API's or tools that would allow me to write a program to perform a series of batch tests. I know literally nothing about the possibilities of UI automation so any information would be valuable. I don't know that much about Unit testing either, how complicated can the tests be? Is it possible to get Unit tests to use the UI? Are there any other methods I should consider? Thanks for reading, and for any advice in advance.

  • JavaScript and callback nesting

    - by Jake King
    A lot of JavaScript libraries (notably jQuery) use chaining, which allows the reduction of this: var foo = $(".foo"); foo.stop(); foo.show(); foo.animate({ top: 0 }); to this: $(".foo").stop().show().animate({ top: 0 }); With proper formatting, I think this is quite a nice syntactic capability. However, I often see a pattern which I don't particularly like, but appears to be a necessary evil in non-blocking models. This is the ever-present nesting of callback functions: $(".foo").animate({ top: 0, }, { callback: function () { $.ajax({ url: 'ajax.php', }, { callback: function () { ... } }); } }); And it never ends. Even though I love the ease non-blocking models provide, I hate the odd nesting of function literals it forces upon the programmer. I'm interesting in writing a small JS library as an exercise, and I'd love to find a better way to do this, but I don't know how it could be done without feeling hacky. Are there any projects out there that have resolved this problem before? And if not, what are the alternatives to this ugly, meaningless code structure?

  • Ubuntu 12.10 wont boot

    - by John Mark High
    im new to using Ubuntu and just bought a HP Pavilion g6-2240sa with windows 8 pre installed. I made a bootable USB with Ubuntu on it and installed alsongside windows, for 2 days it worked fine, I got into Ubuntu by doing an advanced restart from windows 8 and then booting Ubuntu from the partition it made. When i did the advanced restart today there was only 1 HDD i could select ( there were 3 before windows, a restore partition that was already there when i got the computer and Ubuntu) so i booted from the USB again and re-installed Ubuntu. then did an advanced restart and the 3 partitions where there again, i booted from Ubuntu and now heres my problem. I get the Ubuntu background when its loading then its just a black screen with some writing, its not on long enough to read, then just a black screen with a white _ and the top left corner that does nothing, i have to restat the computer and it auto boots into windows 8. im a little confused as the first time i installed Ubuntu it worked fine until the partition dissaperd), the second time i installed i did everything the same except it found the old Ubuntu so i reinstalled it and now is donst work.

  • F# Application Entry Point

    - by MarkPearl
    Up to now I have been looking at F# for modular solutions, but have never considered writing an end to end application. Today I was wondering how one would even start to write an end to end application and realized that I didn’t even know where the entry point is for an F# application. After browsing MSDN a bit I got a basic example of a F# application with an entry point [<EntryPoint>] let main args = printfn "Arguments passed to function : %A" args // Return 0. This indicates success. 0 Pretty simple stuff… but what happens when you have a few modules in a program – so I created a F# project with two modules and a main module as illustrated in the image below… When I try to compile my program I get a build error… A function labeled with the 'EntryPointAttribute' attribute must be the last declaration in the last file in the compilation sequence, and can only be used when compiling to a .exe… What does this mean? After some more reading I discovered that the Program.fs needs to be the last file in the F# application – the order of the files in a F# solution are important. How do I move a source file up or down? I tried dragging the Program.fs file below ModuleB.fs but it wouldn’t allow me to. Then I thought to right click on a source file and got the following menu.   Wala… to move the source file to the bottom of the solution you can select the “Move Up” or “Move Down” option. Now that I got this right I decided to put some code in ModuleA & ModuleB and I have the start of a basic application structure. ModuleA Code namespace MyApp module ModuleA = let PrintModuleA = printf "hello a \n" ()   ModuleB Code namespace MyApp module ModuleB = let PrintModuleB = printf "hello b \n" ()   Program Code // Learn more about F# at http://fsharp.net #light namespace MyApp module Main = open System [<EntryPoint>] let main args = ModuleA.PrintModuleA let endofapp = Console.ReadKey() 0

  • Is the addition of a duration to a date-time defined in ISO 8601?

    - by Benjamin
    I've writing a date-time library, and need to implement the addition of a duration to a date-time. If I add a 1 month duration: P1M to the 31st March 2012: 2012-03-31, does the standard define what the result is? Because the resulting date (31st April) does not exist, there are at least two options: Fall back to the last day of the resulting month. This is the approach currently taken by the ThreeTen API, the (alpha) reference implementation of JSR-310: ZonedDateTime date = ZonedDateTime.parse("2012-03-31T00:00:00Z"); Period duration = Period.parse("P1M"); System.out.println(date.plus(duration).toString()); // 2012-04-30T00:00Z Carry the extra day to the next month. This is the approach taken by the DateTime class in PHP: $date = new DateTime('2012-03-31T00:00:00Z'); $duration = new DateInterval('P1M'); echo $date->add($duration)->format('c'); // 2012-05-01T00:00:00+00:00 I'm surprised that two date-time libraries contradict on this point, so I'm wondering whether the standard defines the result of this operation?

  • Is application-specific data required for good unit testing?

    - by stinkycheeseman
    I am writing unit tests for a fairly simple function that depends on a fairly complicated set of data. Essentially, the object I am manipulating represents a graph and this function determines whether to chart a line, bar, or pie chart based on the data that came back from the server. This is a simplified version, using jQuery: setDefaultChartType: function (graphObject) { var prop1 = graphObject.properties.key; var numCols = 0; $.each(graphObject.columns, function (colIndex, column) { numCols++; }); if ( numCols > 6 || ( prop1 > 1 && graphObject.data.length == 1) ) { graphObject.setChartType("line"); } else if ( numCols <=6 && prop1 == 1 ) { graphObject.setChartType("bar"); } else if ( numCols <=6 && prop1 > 1 ) { graphObject.setChartType("pie"); } } My question is, should I use mock data that is procured from the actual database? Or can I just fabricate data that fits the different cases? I'm afraid that fabricating data will not expose bugs arising from changes in the database, but on the other hand, it would require a lot more effort to keep the test data up-to-date that I'm not sure is necessary.

  • I still can't figure out how to program!

    - by Mark K.
    Please help! I've read lots of programming books for various languages, Java, Python, C, etc. I understand and know all of the basics of the languages and I understand algorithms and data structures. (Equivilant of say 2 years of CompSci classes) BUT, I still can't figure how to write a program that does anything useful. All of the programming books show you how to write the language, but NOT how to use it! The programming examples are all very basic like build a card catalog for a library or a simple game or use algorithms etc... They dont't show you how to develop complex programs that actually do anything useful! I've looked a open-source programs on sourceforge, but they don't make much sense to me. There are hundreds of files in each program & thousands of lines of code. But how do I learn how to do this? There's nothing in any book I can buy on Amazon that will give me the tools to write any of these programs. How do you go from reading Intro to Java or Programming Python, or C Programming Language, etc.. to actually being able to say, I have an idea for X Program.. this is how I go about developing it? It seems like there is so much more involved in writing a program than you can learn in a book or from a class. I feel like there is someth Can anyone put me on the right track?

  • VMware Player 5.0 or VMware Workstation 9.0 after upgrade to Ubuntu 12.10

    The upgrade process Upgrading Ubuntu 12.04 to latest version 12.10 - aka Quantal Quetzal - is straight forward and you only need to follow the offical upgrade instructions. Short version on the console looks like this: sudo do-release-upgrade This will update the repository entries, and start the upgrade process. After some minutes or hours of download and installation, you have to reboot your system once to get the new kernel loaded. As time of writing, I'm on '3.5.0-17-generic'. And as with any modification of the kernel version, you have to compile the necessary kernel modules to get VMware Player or Workstation up and running. Usually, this happens the first time you try start your VMware software and that's it. Well, again not so this time. Getting the kernel patch Luckily, the community over VMware is very active and you can get a new kernel patch in the online forums here. Get the download and put in a folder have write permissions. Then you extract the archive on the console like so: tar -xjvf vmware9_kernel35_patch.tar.bz2 Then you change into the newly created folder: cd vmware9_kernel3.5_patch/ And you execute the available shell script as root (superuser) like so: sudo ./patch-modules_3.5.0.sh This will stop any running instances of VMware software, patches the source files and runs the compile process for your active environment. This might take some time depending on your machine, and once completed you can start VMware Player or Workstation as previously. In case that you are going to apply the patch again, the script will simply quit with the following output: /usr/lib/vmware/modules/source/.patched found. You have already patched your sources. Exiting You might remove the .patched file in case that you upgraded/changed your kernel and you need to apply the patch again. Disclaimer: The patch is "as-is" and the patcher is originally created by Artem S. Tashkinov, and later modified by An_tony. Please refer to the VMware forum in case of questions or problems. There are also patches available for older versions of VMware Player or Workstation.

  • Extracting useful information from free text

    - by insta
    We filter and analyse seats for events. Apparently writing a domain query language for the floor people isn't an option. I'm using C# 4.0 & .NET 4.0, and have relatively free reign to use whatever open-source tools are available. </background-info> If a request comes in for "FLOOR B", the sales people want it to show up if they've entered "FLOOR A-FLOOR F" in a filter. The only problem I have is that there's absolutely no structure to the parsed parameters. I get the string already concatenated (it actually uses a tilde instead of dash). Examples I've seen so far with matches after each: 101WC-199WC (needs to match 150WC) AAA-ZZZ (needs to match AAA, BBB, ABC but not BB) LOGE15-LOGE20 (needs to match LOGE15 but not LOGE150) At first I wanted to try just stripping off the numeric part of the lower and upper, and then incrementing through that. The problem I have is that only some entries have numbers, sometimes the numbers AND letters increment, sometimes its all letters that increment. Since I can't impose any kind of grammar to use (I really wanted [..] expansion syntax), I'm stuck using these entries. Are there any suggestions for how to approach this parsing problem?

  • IEEE SRS documents: lightweight version when working with outside contractors?

    - by maple_shaft
    Typically we follow an Agile development process that tends not to put an emphasis on writing requirements and technical documents that nobody will read. We tend to focus our limited manpower to development and testing activities with collaborative design and whiteboarding as a key focus. There is a mostly standalone web component that will take quite a few weeks to develop, but this work can be mostly parallel with other project work going on. To try and catch up time I was given a budget for hiring a developer on oDesk to complete this work. While my team isn't accustomed to working off of a firm SRS document, I realize that with outsourced development that it is a good idea to be as firm and specific as possible so I realize that I need to provide a detailed Requirements and Technical Specification document for this work to be done correctly. When I do write a Requirements document I typically utilize the standard IEEE SRS document template but I think this is too verbose and probably overkill for what I need to communicate to a developer. Is there another requirements document that is more lightweight and also accepted by a major standards organization like the IEEE? Further, as what will be developed as a software module that will interact with other software modules, my requirements really need to delve into technical specifications for things to work correctly. In this scenario does it make sense to merge technical and requirements specifications into a single document, and if not, what is a viable alternative?

  • I've got my Master's in Software Engineering... Now what? [closed]

    - by Brian Driscoll
    Recently I completed a Master of Science in Software Engineering from Drexel University (Philadelphia, PA, US), because I wanted to have some formal education in software (my undergrad is in Math Ed) and also because I wanted to be able to advance my career beyond just programming. Don't get me wrong; I love to code. I spend a lot of my spare time coding. However, for me writing code is just a means to an end: what I REALLY love is designing software. Not visual design, mind you, but the architecture of the system. So, ideally I'd like to try to get a job doing software architecture. The problem is that I have no real experience in it besides my graduate course work. So, what should I do to make my "bones" in software architecture? UPDATE Just so it's clear, I have over 5 years of work experience in software development and an MCTS cert in addition to my education, so I'm not looking for the usual "I'm fresh out of school, what should I do?" advice.
