  • Detecting Markers Using OpenCV

    - by Hamza Yerlikaya
    I am trying to detect various objects containing colored markers, so a red blue green marker identifies object A, and a red blue red marker identifies object B. My problem is I can't use template matching cause objects can be rotated, currently I am thinking about check for each color then find the object by checking the distance between colors but it seems inefficient, so my question is there a better way to do this?

  • Will sharpening my sword eventually lead to it cutting my head off?

    - by Achilles
    Sharpening the sword: All I've read in the developer community suggests that I should keep learning and studying to become the best developer I can. This will make me better at my job and more valuable as an employee. Cutting my head off: However there seems to be an influx of cheap programming labor constantly coming int to the market(college, foreign countries, etc.) I was part of that influx when I graduated. So my question is, What is the likely outcome? Will there always be a job where a skilled-programmer(Grey-Beard) will have a place to work and contribute, or will he eventually price himself out of the market by having such great knowledge and skill?

  • Sending url params and POST body to a MVC 2 Controller

    - by Luiggi
    Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

  • Lock web app only work for intranet

    - by justjoe
    some week in the future i will have job to create php web app that will work as billing process. As the client and my team agree upon, the web app will only deploy in their internal server. This need arose some fundamental questions for myself. how do we lock the web app really really will work only in internal server and not in internet as it asked ? cause this need, the cost for the job have been cut into some degree. so it will be best if it only work as client describe it : it will be deploy in intranet an intranet only What is the pro and cons deploy php application only (with all of its apache server )in intranet ? What is the fundamental different between deploying php app in intranet environment and in internet ? is there anything to be consider ? I know we can put windows in to a flash-disk or pen-disk. i there any autorun apache/php server that work in the same fashion ?

  • unable to retract Sharepoint solutions

    - by BeraCim
    Hi all: I am having trouble retracting solutions in SharePoint 2007. I used both the retract solution button and the stsadm command in command line. The timer job was created in both instances, but it never gets run... it just sits in the timer job definition. The Status of the target just said "Retracting (scheduled at m/dd/yyyy MM:SS AM/PM)". I've waited for a long time and nothing happens. Has anyone experienced this before, and does anyone have a solution to this problem? Thanks.

  • Can learning a new language (Human not programming) help your career?

    - by Omar Kooheji
    I was wondering if anyone had any experience of learning a new language (a human language not a programming one) and whether is has helped you get ahead in your career. I'm assuming that the new language is one other than English which I think is fairly essential to programming as most programming resources seem to be english. The reason I ask is I speak Arabic and was told that it would give me an edge when I was looking for jobs, and yet so far in my current job it's completely irrelevant and in my last job I had it was used but I didn't get any special "appreciation" for speaking it.

  • Load balancing and scheduling algorithms.

    - by Lukas Šalkauskas
    Hello there, so here is my problem: I have several different configuarion servers. I have different calculations (jobs); I can predict how long approximately each job will take to be caclulated. Also, I have priorities. My question is how to keep all machines loaded 99-100% and schedule the jobs in the best way. Each machine can do several calculations at a time. Jobs are pushed to the machine. The central machine knows the current load of each machine. Also, I would like to to assign some kind of machine learning here, because I will know statistics of each job (started, finished, cpu load etc.). How can I distribute jobs (calculations) in the best possible way, keeping in mind the priorities? Any suggestions, ideas, or algorithms ? FYI: My platform .NET.

  • Dragging Custom Node in JavaFX

    - by Karussell
    I cannot get it working although I am very close to an acceptable solution. I can drag the Dock if it is only a rectangle. But if I add a node (e.g. an image) to this dock I am not able to get a working solution. Do you have a code snippet, link or other advices for me? Here is my code: public class Dock extends CustomNode { // initialize this with an 64x64 image of your choice // via ImageView { image: Image {..}} public var content: Node[]; public var width = 64; public var height = 64; public var xOffset: Number = 0; public var yOffset: Number = 0; var imgX: Number = 0; var imgY: Number = 0; var distX: Number; var distY: Number; public var rasterX = function (n: Number): Number { var MAX = 4 * 64; if (n < 0) { return 0 } else if (n > MAX) { return MAX } else return n } public var rasterY = rasterX; override protected function create(): Node { Group { // if we place the translate here then the whole dock will flicker //translateX: bind imgX; //translateY: bind imgY; content: [ Rectangle { // ... and here 'content' won't be dragged translateX: bind imgX; translateY: bind imgY; height: bind height width: bind width fill: Color.LIGHTGRAY strokeWidth: 4 stroke: Color.BLACK }, content] onMousePressed: function (e: MouseEvent): Void { xOffset = e.x; yOffset = e.y; // Calculate the distance of the mouse point from the image // top-left corner which will always come out as positive value distX = e.x - imgX; distY = e.y - imgY; } onMouseDragged: function (e: MouseEvent): Void { // Find out the new image postion by subtracting the distance // part from the mouse point. imgX = rasterX(e.x - distX); imgY = rasterY(e.y - distY); } } }

  • K-means algorithm variation with minimum measure of size

    - by user1464628
    I'm looking for some algorithm such as k-means for grouping points on a map into a fixed number of groups, by distance. The number of groups has already been decided, but the trick part (at least for me) is to meet the criteria that the sum of MOS of each group should in the certain range, say bigger than 1. Is there any way to make that happen? ID MOS X Y 1 0.47 39.27846 -76.77101 2 0.43 39.22704 -76.70272 3 1.48 39.24719 -76.68485 4 0.15 39.25172 -76.69729 5 0.09 39.24341 -76.69884

  • Which programming language is easiest to get a junior position in?

    - by markle976
    I do not have a CS degree but I have lots of intermediate experience with many languages (PHP, C#, Objective-C, Java, VBScript, Actionscript, Javascript, Ruby, etc), mostly freelance or pastime. I have a little experience with Linux (Ubuntu), and a decent bit with Windows. When I look at different languages I find that am interested in most (except maybe VB), but I am not sure what to focus on. So what would be the easiest language to get a job in? Java? PHP? Or would it be easier to get a job as a Junior DBA if I learned Oracle or SQL Server in my spare time?

  • Parsing string logic issue c#

    - by N0xus
    This is a follow on from this question My program is taking in a string that is comprised of two parts: a distance value and an id number respectively. I've split these up and stored them in local variables inside my program. All of the id numbers are stored in a dictionary and are used check the incoming distance value. Though I should note that each string that gets sent into my program from the device is passed along on a single string. The next time my program receives that a signal from a device, it overrides the previous data that was there before. Should the id key coming into my program match one inside my dictionary, then a variable held next to my dictionaries key, should be updated. However, when I run my program, I don't get 6 different values, I only get the same value and they all update at the same time. This is all the code I have written trying to do this: Dictionary<string, string> myDictonary = new Dictionary<string, string>(); string Value1 = ""; string Value2 = ""; string Value3 = ""; string Value4 = ""; string Value5 = ""; string Value6 = ""; void Start() { myDictonary.Add("11111111", Value1); myDictonary.Add("22222222", Value2); myDictonary.Add("33333333", Value3); myDictonary.Add("44444444", Value4); myDictonary.Add("55555555", Value5); myDictonary.Add("66666666", Value6); } private void AppendString(string message) { testMessage = message; string[] messages = message.Split(','); foreach(string w in messages) { if(!message.StartsWith(" ")) outputContent.text += w + "\n"; } messageCount = "RSSI number " + messages[0]; uuidString = "UUID number " + messages[1]; if(myDictonary.ContainsKey(messages[1])) { Value1 = messageCount; Value2 = messageCount; Value3 = messageCount; Value4 = messageCount; Value5 = messageCount; Value6 = messageCount; } } How can I get it so that when programs recives the first key, for example 1111111, it only updates Value1? The information that comes through can be dynamic, so I'd like to avoid harding as much information as I possibly can.

  • How can I correctly display my AVL Tree in LaTex? A solo left-child hangs straight down....

    The below code almost works perfectly, however the child of 9, 7, hangs straight down instead of as a left-child. How can I correct this? \usepackage{tikz} \usepackage{xytree} \begin{tikzpicture}[level/.style={sibling distance=60mm/#1}] \node [circle,draw] {4} child { node [circle,draw] {2} child {node [circle,draw] {1} } child { node [circle,draw]{3} } } child {node [circle,draw] {6} child {node [circle,draw] {5} } child {node [circle,draw] {9} child {node [circle, draw] {7}} } }; \end{tikzpicture}} Thanks, CB

  • Approaches for Content-based Item Recommendations

    - by PartlyCloudy
    Hello, I'm currently developing an application where I want to group similar items. Items (like videos) can be created by users and also their attributes can be altered or extended later (like new tags). Instead of relying on users' preferences as most collaborative filtering mechanisms do, I want to compare item similarity based on the items' attributes (like similar length, similar colors, similar set of tags, etc.). The computation is necessary for two main purposes: Suggesting x similar items for a given item and for clustering into groups of similar items. My application so far is follows an asynchronous design and I want to decouple this clustering component as far as possible. The creation of new items or the addition of new attributes for an existing item will be advertised by publishing events the component can then consume. Computations can be provided best-effort and "snapshotted", which means that I'm okay with the best result possible at a given point in time, although result quality will eventually increase. So I am now searching for appropriate algorithms to compute both similar items and clusters. At important constraint is scalability. Initially the application has to handle a few thousand items, but later million items might be possible as well. Of course, computations will then be executed on additional nodes, but the algorithm itself should scale. It would also be nice if the algorithm supports some kind of incremental mode on partial changes of the data. My initial thought of comparing each item with each other and storing the numerical similarity sounds a little bit crude. Also, it requires n*(n-1)/2 entries for storing all similarities and any change or new item will eventually cause n similarity computations. Thanks in advance! UPDATE tl;dr To clarify what I want, here is my targeted scenario: User generate entries (think of documents) User edit entry meta data (think of tags) And here is what my system should provide: List of similar entries to a given item as recommendation Clusters of similar entries Both calculations should be based on: The meta data/attributes of entries (i.e. usage of similar tags) Thus, the distance of two entries using appropriate metrics NOT based on user votings, preferences or actions (unlike collaborative filtering). Although users may create entries and change attributes, the computation should only take into account the items and their attributes, and not the users associated with (just like a system where only items and no users exist). Ideally, the algorithm should support: permanent changes of attributes of an entry incrementally compute similar entries/clusters on changes scale something better than a simple distance table, if possible (because of the O(n²) space complexity)

  • Solution for distributing MANY simple network tasks?

    - by EmpireJones
    I would like to create some sort of a distributed setup for running a ton of small/simple REST web queries in a production environment. For each 5-10 related queries which are executed from a node, I will generate a very small amount of derived data, which will need to be stored in a standard relational database (such as PostgreSQL). What platforms are built for this type of problem set? The nature, data sizes, and quantities seem to contradict the mindset of Hadoop. There are also more grid based architectures such as Condor and Sun Grid Engine, which I have seen mentioned. I'm not sure if these platforms have any recovery from errors though (checking if a job succeeds). What I would really like is a FIFO type queue that I could add jobs to, with the end result of my database getting updated. Any suggestions on the best tool for the job?

  • MaximumErrorCount has now effect

    - by Rob Bowman
    Hi I'm quite new to SSIS - using 2008 version. I have a job that uses a few data flow tasks. On the third one I'm getting a primary key violation on the last row that it needs to insert, but only sometimes! I'd like to ignore this problem for now and let the job continue. I have set the MaximumErrorCount property to 10 for the DataFlowTaks, the SequenceContainer and for the Package but still taks fails and this causes the package to stop. Could anyone please advise how I can get the package to ignore the error? Thanks Rob.

  • Syntax error while copying an multidimensional array to another in C

    - by mantuko
    We are programming a ST269 microcontroller which has two IR distance sensors. To calibrate these sensors we made one table for each sensor with the distance we measured and the corresponding value we get from the ADC. Now we want to use one function to approximate the values in between. So we defined two two-dimensional arrays (one for each sensor) as global variables. In our function we then want to copy the one array we want to work with to a working array and approximate our values. So here's the code: ... unsigned int ir_werte_re[][] = { {8,553}, ... {83,133} }; unsigned int ir_werte_li[][] = { {8,566}, ... {83,147} }; ... unsigned int geradenaproximation(unsigned int messwert, unsigned int seite) { unsigned int working_array[16][16]; unsigned int i = 0; if (seite == 0) { for (i = 0; i < sizeof(working_array); i++) { working_array[i][0] = ir_werte_li[i][0]; i++; } } else { for (i = 0; i < sizeof(working_array); i++) { working_array[i][0] = ir_werte_re[i][0]; i++; } } i = 0; unsigned int y1 = 0; unsigned int x1 = 0; ... } This code is in a file called sensor.c. We didn't write anything about our global arrays in the sensor.h should we? The sensor.h of course is included in our main.c and there the function is called. We also tried to copy the arrays via memcpy(working_array, ir_werte_li, sizeof(working_array)); And in every way we do this we get a syntax error near unsigned in the line where we're declaring unsigned int y1 = 0; and I'm pretty sure that there is no syntax error in this line : ) The last time I spend coding in C is a few years away so I'm not sure if the way we try to do this is good. Perhaps we can solve this by using a pointer instead of really copying the array or something. So please help me out I'll appreciate your bits on this.

  • Getting up to speed on modern architecture

    - by Matt Thrower
    Hi, I don't have any formal qualifications in computer science, rather I taught myself classic ASP back in the days of the dotcom boom and managed to get myself a job and my career developed from there. I was a confident and, I think, pretty good programmer in ASP 3 but as others have observed one of the problems with classic ASP was that it did a very good job of hiding the nitty-gritty of http so you could become quite competent as a programmer on the basis of relatively poor understanding of the technology you were working with. When I changed on to .NET at first I treated it like classic ASP, developing stand-alone applications as individual websites simply because I didn't know any better at the time. I moved jobs at this point and spent the next several years working on a single site whose architecture relied heavily on custom objects: in other words I gained a lot of experience working with .NET as a middle-tier development tool using a quite old-fashioned approach to OO design along the lines of the classic "car" class example that's so often used to teach OO. Breaking down programs into blocks of functionality and basing your classes and methods around that. Although we worked under an Agile approach to manage the work the whole setup was classic client/server stuff. That suited me and I gradually got to grips with .NET and started using it far more in the manner that it should be, and I began to see the power inherent in the technology and precisely why it was so much better than good old ASP 3. In my latest job I have found myself suddenly dropped in at the deep end with two quite young, skilled and very cutting-edge programmers. They've built a site architecture which is modelling along a lot of stuff which is new to me and which, in truth I'm having a lot of trouble understanding. The application is built on a cloud computing model with multi-tenancy and the architecture is all loosely coupled using a lot of interfaces, factories and the like. They use nHibernate a lot too. Shortly after I joined, both these guys left and I'm now supposedly the senior developer on a system whose technology and architecture I don't really understand and I have no-one to ask questions of. Except you, the internet. Frankly I feel like I've been pitched in at the deep end and I'm sinking. I'm not sure if this is because I lack the educational background to understand this stuff, if I'm simply not mathematically minded enough for modern computing (my maths was never great - my approach to design is often to simply debug until it works, then refactor until it looks neat), or whether I've simply been presented with too much of too radical a nature at once. But the only way to find out which it is is to try and learn it. So can anyone suggest some good places to start? Good books, tutorials or blogs? I've found a lot of internet material simply presupposes a level of understanding that I just don't have. Your advice is much appreciated. Help a middle-aged, stuck in the mud developer get enthusastic again! Please!
