  • What's the best way to manage reusable classes/libraries separately?

    - by Tom
    When coding, I naturally often come up with classes or a set of classes with a high reusability. I'm looking for an easy, straight-forward way to work on them separately. I'd like to be able to easily integrate them into any project; it also should be possible to switch to a different version with as few commands as possible. Am I right with the assumption that git (or another VCS) is best suited for this? I thought of setting up local repositories for each class/project/library/plugin and then just cloning/pulling them. It would be great if I could reference those projects by name, not by the full path. Like git clone someproject. edit: To clarify, I know what VCS are about and I do use them. I'm just looking for a comfortable way to store and edit some reusable pieces of code (including unit tests) separately and to be able to include them (without the unit tests) in other projects, without having to manually copy files. Apache Maven is a good example, but I'm looking for a language-independent solution, optimally command-line-based.

  • PASS Summit Preconference and Sessions

    - by Davide Mauri
    I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query. See you there!!!!!

  • I need a form to tie MySQL Records together.

    - by John R
    I need a HTML-based form to tie database records together. The user scenario that I envision is somthing like this: A super-user does a search of the database and is delivered a table of records based on that search; each record is numbered with the database-record id. There would also be two text fields next to each record. These text fields would allow: the user to make a reference from one record to another. For example, a user could enter into record id #457 the integer 242 to indicate that there is a correlation with record ID #242. The user would also describe the type of relationship it is. This could be accomplished with a simple integer in the second field that indicates the type of relationship between the two records. When the super-user hits the submit button, all of these relationships are saved in a mySqljoin table. One option is to give me advice on how to implement and code this myself in PHP. However, before I reinvent the wheel, another option is to lead me to a free script that does something similar.

  • How did we get saddled with the (hierarchical) filesystem as the basic data structure?

    - by user1936
    I'm self-taught and I don't have a CS degree. The more I've been learning about data structure, the more I wonder, in this day and age, how are we still saddled with the filesystem, with directories and files, as the basic data storage structure on the OS? I understand the simplicity of it, but it seems nowadays that there could be more options available natively. As far as I'm aware, the only project to improve the basic functionality of the filesystem was ReiserFS, where you could tell what line of a file was changed by whom, and when. For instance, if I could have native tagging for files, where I could tag images, diagrams, word-processing documents, an entire code repository, all as belonging to a single project, that would really be helpful to me. Since I'm stuck in the filesystem paradigm, I know that I could put all those into a single folder/directory, but what if they already exist in disparate directories, and they need to stay there? I know there are programs out there that can do this, but why aren't they on the filesystem? Something that would be nice to have is some kind of relational feature in the filesystem, like you get with RDBMSes. I understand that that was supposed to be part of Vista/7, but that fell off the feature list too. Sure, any program can store a binary file and have any data structure it wants in it, by why couldn't the OS offer more complex ways of storing data, beyond the simple heirarchy of the filesystem?

  • At the Java DEMOgrounds - Java EE 7 WebSocket Early Access

    - by Janice J. Heiss
    At the packed and happening Java DEMOgrounds, I wandered over to check out Java EE Web Profile and Platform Technologies. Martin Matula, a Senior Development Manager at Oracle on the JavaEE/GlassFish team, responsible for the area of web services (including JAX-WS and JAX-RS), was demonstrating Java EE Web Profile and Platform Technologies.Matula was previewing some Java EE 7 WebSocket early access features via a group drawing application that showcases the upcoming JSR 356, “Java API for WebSocket”, which is the API for building RESTful web services and Server-Sent Events, an HTML5 feature. He emphasized that this is supported in Jersey, the reference implementation for JAX-RS, as well.“In this demo,” Matula explained, “I have a simple JavaScript front-end talking to the back-end deployed on GlassFish. It uses RESTful web services to get the list of drawings we have. I can create new drawings and the list is updated immediately using the Server-Sent Events, so the message is coming from the server to the client. Everything is getting updated live using WebSocket, which is the bi-directional communication new protocol in HTML5. This is using Project Jersey and Project Tyrus. Tyrus is the implementation of WebSocket protocol for Java. Jersey implements the RESTful APIs as well as the Server-Sent Events protocol.”

  • Using ConcurrentQueue for thread-safe Performance Bookkeeping.

    - by Strenium
    Just a small tidbit that's sprung up today. I had to book-keep and emit diagnostics for the average thread performance in a highly-threaded code over a period of last X number of calls and no more. Need of the day: a thread-safe, self-managing stats container. Since .NET 4.0 introduced new thread-safe 'Collections.Concurrent' objects and I've been using them frequently - the one in particular seemed like a good fit for storing each threads' performance data - ConcurrentQueue. But I wanted to store only the most recent X# of calls and since the ConcurrentQueue currently does not support size constraint I had to come up with my own generic version which attempts to restrict usage to numeric types only: unfortunately there is no IArithmetic-like interface which constrains to only numeric types – so the constraints here here aren't as elegant as they could be. (Note the use of the Average() method, of course you can use others as well as make your own).   FIFO FixedSizedConcurrentQueue using System;using System.Collections.Concurrent;using System.Linq; namespace xxxxx.Data.Infrastructure{    [Serializable]    public class FixedSizedConcurrentQueue<T> where T : struct, IConvertible, IComparable<T>    {        private FixedSizedConcurrentQueue() { }         public FixedSizedConcurrentQueue(ConcurrentQueue<T> queue)        {            _queue = queue;        }         ConcurrentQueue<T> _queue = new ConcurrentQueue<T>();         public int Size { get { return _queue.Count; } }        public double Average { get { return _queue.Average(arg => Convert.ToInt32(arg)); } }         public int Limit { get; set; }        public void Enqueue(T obj)        {            _queue.Enqueue(obj);            lock (this)            {                T @out;                while (_queue.Count > Limit) _queue.TryDequeue(out @out);            }        }    } }   The usage case is straight-forward, in this case I’m using a FIFO queue of maximum size of 200 to store doubles to which I simply Enqueue() the calculated rates: Usage var RateQueue = new FixedSizedConcurrentQueue<double>(new ConcurrentQueue<double>()) { Limit = 200 }; /* greater size == longer history */   That’s about it. Happy coding!

  • Sorting for 2D Drawing

    - by Nexian
    okie, looked through quite a few similar questions but still feel the need to ask mine specifically (I know, crazy). Anyhoo: I am drawing a game in 2D (isometric) My objects have their own arrays. (i.e. Tiles[], Objects[], Particles[], etc) I want to have a draw[] array to hold anything that will be drawn. Because it is 2D, I assume I must prioritise depth over any other sorting or things will look weird. My game is turn based so Tiles and Objects won't be changing position every frame. However, Particles probably will. So I am thinking I can populate the draw[] array (probably a vector?) with what is on-screen and have it add/remove object, tile & particle references when I pan the screen or when a tile or object is specifically moved. No idea how often I'm going to have to update for particles right now. I want to do this because my game may have many thousands of objects and I want to iterate through as few as possible when drawing. I plan to give each element a depth value to sort by. So, my questions: Does the above method sound like a good way to deal with the actual drawing? What is the most efficient way to sort a vector? Most of the time it wont require efficiency. But for panning the screen it will. And I imagine if I have many particles on screen moving across multiple tiles, it may happen quite often. For reference, my screen will be drawing about 2,800 objects at any one time. When panning, it will be adding/removing about ~200 elements every second, and each new element will need adding in the correct location based on depth.

  • Need advice: Staying techie or going the MBA way?

    - by SharePoint Newbie
    I know this is a very subjective question and I am the best person to decide this for myself...but I am just looking for your views. I have 5 years of experience as a professional developer. I have a decent background in Maths and have done my bachelors in engineering in CS. I have still not reached a stage in my career where growth is difficult and do not foresee this happenning for a very long time if ever because I find myself constantly (self) motivated to pick up new skills. A lot of my friends have however been getting through their MBA lately ...and not from the likes of Harvard or Kellogs, just mediocre colleges. They've however been landing paychecks fatter than me even though they have little or no work experience. Given that I have the option of pursuing an MBA an have my finances in order (and am planning an MBA from INSEAD / IE) would it make sense for me to sell out what I like doing and go for an MBA? Will I regret not doing an MBA later, given that I am in the right age/experience group to do an MBA? I absolutely love what I am doing right now and also the people I'm doing it with, but am just worried if this career would be as rewarding financially as the one after a management degree.

  • Why is Ubuntu unmounting my primary hard drive?

    - by Twisol
    I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out? EDIT: It just happened again, and I heard a small little clicky sound from the hard drive about five seconds before things went south. I'm thinking I should start backing up ASAP. In response to a comment, here's the dmesg output: http://askubuntu.pastebin.com/uYGshBay Also, the SMART status says the disk has a few bad sectors, and the detailed data says there are 14. It says it passed the self-assessment though. Lastly, this doesn't seem to be happening when I'm on Windows. I recently re-enabled ureadahead (which I disabled ages ago because it was causing Ubuntu to hang at the startup logo), could that be the source of the problem? I've disabled it again to see.

I see a lot of these questions as closed and there is no real answer given I will try any solutions available and report results so that others can also solve problems not be overwhelmed by overly broad troubleshooting guides that do nothing to help solve specific issues The nomodeset change from quiet splash also yields no results on reboot I still get a blank screen this screen still has contorl alt f1 abilities but that is it contorl alt f8 causes blinking cursor and F7 gets a crazy flash with green and blue then blank screen Contorl alt f1 a log in prompt in text only when run in recovery mode with failsafe graphics its says the syestem is running in low graphics mode your screen graphics card and input device settings could not be detected correctly.

  • jump pads problem

    - by Pasquale Sada
    I'm trying to make a character jump on a landing pad who stays above him. Here is the formula I've used (everything is pretty much self-explainable, maybe except character_MaxForce that is the total force the character can jump ): deltaPosition = target - character_position; sqrtTerm = Sqrt(2*-gravity.y * deltaPosition.y + MaxYVelocity* character_MaxForce); time = (MaxYVelocity-sqrtTerm) /gravity.y; speedSq = jumpVelocity.x* jumpVelocity.x + jumpVelocity.z *jumpVelocity.z; if speedSq < (character_MaxForce * character_MaxForce) we have the right time so we can store the value jumpVelocity.x = deltaPosition.x / time; jumpVelocity.z = deltaPosition.z / time; otherwise we try the other solution time = (MaxYVelocity+sqrtTerm) /gravity.y; and then store it jumpVelocity.x = deltaPosition.x / time; jumpVelocity.z = deltaPosition.z / time; jumpVelocity.y = MaxYVelocity; rigidbody_velocity = jumpVelocity; The problem is that the character is jumping away from the landing pad or sometime he jumps too far never hitting the landing pad.

  • Finding the best practice for a game simulating tool

    - by Tougheart
    I'm studying Java right now, and I'm thinking of this tool as my practice project. The game is "League of Legends" in case anyone knows it, I'm not actually simulating the game as in simulating game play, I'm just trying to create a tool that can compare different champions to each other based on their own abilities and items bought inside the game. The game basics are: Every player has a champion in a team of 5 players playing against another team. Each champion has a different set of abilities (usually 4) that s/he uses to do damage to opposing champions. Each champion gets stronger by buying different items, increasing the attack it deals or decreasing the damage received. What I want to do is to create a tool to be used outside the game enabling players to try out different builds for their champions and compare the figures against other champions they usually fight against. The goal is to enable players get a deeper understanding of the different item combinations (builds) that can be used during the games, instead of trying them out in real games which can be somehow very time consuming. What I'm stuck at is the best practice I should follow to make this possible using Java, I can't figure out which classes should inherit from which, should I make champions and items specs in the code or extracted from other files, specially that I'm talking about hundreds of items and champions to use in that tool. I'm self studying Java, and I don't have much practice at it, so I would really appreciate any broad guidelines regarding this, and sorry if my question doesn't fit here, I tried to follow the rules. English isn't my native language, so I'm really sorry if I wasn't clear enough, I would be more than happy to explain anything that's not understood.

  • Applying Service Pack 1 to Team Foundation Server 2010

    - by Enrique Lima
    Disclosure:  I performed the following activities on my Windows 7 SP1 system, Visual Studio 2010 SP1 and a local Basic installation of TFS 2010. As with any deployment of a service pack into a server environment, take your recommended precautions and be aware of the changes you are putting in.  With that said, make sure you backup your databases, and that you have an exit/rollback strategy in the event of an unexpected situation. Team Foundation Server 2010 Service Pack 1 corresponds to KB2182621.  The KB article is http://support.microsoft.com/kb/2182621 The process will be very simple to follow, you will need to execute the mu_team_foundation_server_2010_sp1_x86_x64_651711.exe file.  That will extract files needed and launch the wizard driven Installation. Once this process completes, you need to validate the changes. By looking at Team Foundation Server 2010 Administration Console, you should see the reference to the KB number and SP1. There is also a good reason to validate log locations and records. From the Team Foundation Server 2010 Administration Console. Or from Windows Explorer, go to the C:\ProgramData\Microsoft\Team Foundation\Server Configuration\Logs location and review the logs referenced by the servicing references.

  • .NET XPath Returns No Results

    - by Stacy Vicknair
    When using XPath in .NET one of the gotchas to be aware of is that all namespaces must be named, otherwise you’ll end up with no results. Default namespaces that are specified with xmlns alone still need to be recognized in the XPath query! Say I had a bit of XML like what is returned from the QueryService web service in Sharepoint: 1: <?xml version="1.0" encoding="UTF-8"?> 2: <ResponsePacket xmlns="urn:Microsoft.Search.Response"> 3: <Response> 4: <Range> 5: ... 6: <Results> 7: <Document xmlns="urn:Microsoft.Search.Response.Document" relevance="849"> 8: ...   When consuming and navigating this response with XPath it is necessary to name all namespaces. Then those named namespaces must be used in reference to the individual element being requested (i.e. doc:Document). In VB: 1: Dim xdoc = new XPathDocument(reader) 2: Dim nav = xdoc.CreateNavigator() 3: Dim nsMgr = new XmlNamespaceManager(nav.NameTable) 4: nsMgr.AddNamespace("resp", "urn:Microsoft.Search.Response") 5: nsMgr.AddNamespace("doc", "urn:Microsoft.Search.Response.Document") 6:  7: Dim results = nav.Select("//doc:Document", nsMgr)   In C#: 1: var xdoc = new XPathDocument(reader); 2: var nav = xdoc.CreateNavigator(); 3: var nsMgr = new XmlNamespaceManager(nav.NameTable); 4:  5: nsMgr.AddNamespace("resp", "urn:Microsoft.Search.Response"); 6: nsMgr.AddNamespace("doc", "urn:Microsoft.Search.Response.Document"); 7:  8: var results = nav.Select("//doc:Document", nsMgr);

  • Recursion in F#

    - by MarkPearl
    Things are slowly coming together – I was able to look at a bit of F# code and intuitively know what it was going to do (yay)… So today I saw a blog post by Bob Palmer on Fibonacci numbers in F# which inspired me to look at bit into recursion. First the C# example… class Program { public static void CountDown(int n) { switch (n) { case 0: Console.WriteLine("End of Count"); break; default: Console.WriteLine(n); CountDown(n-1); break; } } static void Main(string[] args) { CountDown(10); Console.ReadLine(); } }   In F#, the equivalent would look something like this… open System let rec CountDown n = match n with | 0 -> Console.WriteLine("End of Count"); | n -> Console.WriteLine(n); CountDown (n-1); CountDown 10 Console.ReadLine()   Pretty simple stuff. With F# you when making recursive calls you need to explicitly declare that the function is recursive with the “rec” keyword. Otherwise the code is pretty easy to read and self explanatory.

  • I'm a SubVersion geek, why I should consider or not consider Mercurial or Git or any other DRCS?

    - by Pierre 303
    I tried to understand the benefits of DRCS. I must recognize I still doesn't get it. Here are my current beliefs. I'm ready to destroy them thanks to your expertise. I know I'm probably resisting to change. I just want to evaluate how much that change will cost me. Merging hell can be solved by just applying good practices such as continuous integration. There is no such good practice than having a private branch for a few days when you are in a self managing team with real collaboration. I use branching for that for very rare cases, and I keep a branch for every major version, in which I fix bugs merged from the trunk. I see the value of committing offline then pushing online. But continuous integration can help on this too. I work on very large projects, and I never noticed SubVersion to be slow even when the server is 5000km away on the internet and my small connection (less than 1024D/128U). Harddisk space is cheap, so having a copy of source code locally doesn't look like a problem to me. I already have a full copy of the last version on my disk. I don't understand the distributed thing there (maybe THIS IS the key to my understanding?) I not new in the industry, and judging by my difficulty to understand, I don't think DRCS are easier to understand than SubVersion like. If fact, I don't understand... Doctor, give me your diagnostic.

  • Reasons behind polymorphism related behaviour in java

    - by Shades88
    I read this code somewhere class Foo { public int a; public Foo() { a = 3; } public void addFive() { a += 5; } public int getA() { System.out.println("we are here in base class!"); return a; } } public class Polymorphism extends Foo{ public int a; public Poylmorphism() { a = 5; } public void addFive() { System.out.println("we are here !" + a); a += 5; } public int getA() { System.out.println("we are here in sub class!"); return a; } public static void main(String [] main) { Foo f = new Polymorphism(); f.addFive(); System.out.println(f.getA()); // SOP 1 System.out.println(f.a); // SOP 2 } } For SOP1 we get answer 10 and for SOP2 we get answer 3. Reason for this is that you can't override variables whereas you can do so for methods. This happens because type of the reference variable is checked when a variable is accessed and type of the object is checked when a method is accessed. But I am wondering, just why is it that way? Can anyone explain me what is the reason for this behaviour

  • Java - Using Linear Coordinates to Check Against AI [closed]

    - by Oliver Jones
    I'm working on some artificial intelligence, and I want my AI not to run into given coordinates as these are references of a wall/boundary. To begin with, every time my AI hits a wall, it makes a reference to that position (x,y). When it hits the same wall three times, it uses linear check points to 'imagine' there is a wall going through these coordinates. I want to now prevent my AI from going into that wall again. To detect if my coordinates make a straight line, i use: private boolean collinear(double x1, double y1, double x2, double y2, double x3, double y3) { return (y1 - y2) * (x1 - x3) == (y1 - y3) * (x1 - x2); } This returns true is the given points are linear to one another. So my problems are: How do I determine whether my robot is approaching the wall from its current trajectory? Instead of Java 'imagining' theres a line from 1, to 3. But to 'imagine' a line all the way through these linear coordinantes, until infinity (or close). I have a feeling this is going to require some confusing trigonometry?

  • Estimate of Hits / Visits / Uniques in order to fall within a given Alexa Tier?

    - by Alex C
    Hi there! I was wondering if anyone could offer up rough estimates that could tell me how many hits a day move you into a given Alexa rank ? Top 5,000 Top 10,000 Top 50,000 Top 100,000 Top 500,000 Top 1,000,000 I know this is incredibly subjective and thus the broad brush strokes with the number ranges... BUT I've got a site currently ranked just over 1.2M worldwide and over 500k in the USA (http://www.alexa.com/siteinfo/fstr.net) Pretty cool for something hand-built on weekends (pat self on back) I was applying to an ad-platform and was told that their program doesn't accept webmasters who have an Alexa rank of greater than 100,000. (Time to take back that pat on the back I guess). I know that my hits in the last 30 days are somewhere on the order of 15,000 uniques and 20,000 pageviews. So I'm wondering how much harder do I have to work to achieve my next "goals"? I'd like to break into the top million, then re-evaluate from there. It'd be nice to know what those targets translate into (very roughly of course). I imagine that alexa ranks and tiers become very much exponential as you move up the ranks, but even hearing annecdotal evidence from other webmasters would be really useful to me. (ie: I have a site that is ranked X and it got Y hits in the last 30 days) Thanks :) - Alex

  • "Misaligned partition" - Should I do repartition (how?)

    - by RndmUbuntuAmateur
    Tried to install Ubuntu 12.04 from USB-stick alongside the existing Win7 OS 64bit, and now I'm not sure if install was completely successful: Disk Utility tool claims that the Extended partition (which contains Ubuntu partition and Swap) is "misaligned" and recommends repartition. What should I do, and if should I do this repartition, how to do it (especially if I would like not to lose the data on Win7 partition)? Background info: A considerably new Thinkpad laptop (UEFI BIOS, if that matters). Before install there were already a "SYSTEM_DRV" partition, the main Windows partition and a Lenovo recovery partition (all NTFS). Now the table looks like this: SYSTEM_DRV (sda1), Windows (sda2), Extended (sda4) (which contains Linux (sda5; ext4) and Swap (sda6)) and Recovery (sda3). Disk Utility Tool gives a message as follows when I select Ext: "The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested." There were couple of problems during the install, which I describe below, in the case they happen to be relevant. Installer claimed that it recognized existing OS'es fine, so I checked the corresponding option during the install. Next, when it asked me how to allocate the disk space, the first weird thing happened: the installer give me a graphical "slide" allocate disk space for pre-existing Win7 OS and new Ubuntu... but it did not inform me which partition would be for Ubuntu and which for Windows. ..well, I decided to go with the setting installer proposed. (not sure if this is relevant, but I guess I'd better mention it anyway - the previous partition tools have been more self-explanatory...) After the install (which reported no errors), GRUB/Ubuntu refused to boot. Luckily this problem was quite straightforwardly resolved with live-Ubuntu-USB and Boot-Repair ("Recommended repair" worked just fine). After all this hassle I decided to check the partition table "just to be sure"- and the disk utility gives the warning message I described.
