  • Mid level IT lead [closed]

    - by Arihant
    I am a mid level IT lead at a IT support company with 8 years of experience. I don't get a lot of opportunities to learn at my organization since we primarily support existing systems and just fix issues arising on a day to day basis, We are not expected by the parent company to develop solutions from scratch. I aspire to become an Architect. Please guide me how should I plan to acquire the required skills and Knowledge esp since my company doesn't provide me with the right opportunities. The city where i am in doesn't have a lot of s/w development companies they are mostly services companies. Thanks a lot for your replies. Please give me some directions on how do I plan the self learning process ? Personal commitment won't let me move out of my current capacity to join a entry level job outside as of now . Atleast I should be well prepared to grab the opportunity when the time comes.

  • Develop for Desktop and Mobile at once

    - by Hola Soy Edu Feliz Navidad
    I need to develop a programm that is going to read some information from a special USB device and access information via Web Socket (socket.io preferred). My client wants to deploy this app on Mac OS X, Windows, Android and iOS. I was looking for development softwares valid for both: Desktop and Mobile, but it is still not clear for me and that´s what I found. Unity - Looks very good but to create a native plugin for reading from the device it lloks like I need the PRO edition. Adobe Air - Looks good but I´m not sure if I can write Native Plugins for all wanted platforms. LiveCode - Still inmature (lots of bugs) and I don´t know if it is possible to write native plugins for my device. Is there any other good platform for my case? What´s your option?

  • where do you track team Decisions

    - by rerun
    I have been on many development teams and as the team matures decisions about direction are made. These decisions often come back up over and over. Like why don't we fill in this field why didn't we use memcache over a custom solutions. These decisions add up over time and become a significant part of style guides coding standards and unit tests. My question is I have never run into a good way of tracking these decisions or the discovery that went into making them. Does anyone have a best practice.

  • Best Way for Developers to Upload Files to Production Server

    - by ultrajohn
    Small team of developers doing their work here and there. We have a team leader, and is sole responsible for uploading updated source files from the development server to the production server. So let's say, so if an updated files needs to be uploaded to the prod server, that concerned developer shall notify the team lead about it, and then the team lead will update the files to the prod server. So no developer has an access to the prod server except for the team lead. That's our current setup. Now, what we want to do is to give developers a way for uploading their updated files to the server without the team lead intervening in the process. What do you think is the best way to go about this?

  • What should I learn next?

    - by Krysten
    I am a CS major. I've taken 2 courses in C (Intro to C and CS1) and 1 introductory course to OOP with Java. I really like Java and feel that I have a firm understanding of OOP concepts. I am really interested in web development and would like to learn a programming language that can be used to build dynamic web applications. My question is what language should I learn? I've narrowed it down to python or ruby. Also, I want to learn a programming language that will help me get a job upon graduating. So essentially, I will use this particular language to build applications that will help me get a job in the future.

  • What is wrong with me - bug problem? [closed]

    - by reizals
    I have about 6 years exp. in app. development. Not so long ago I had moved to another company and the problem has started. I ready don't know why the last time Im making so many bugs/mistakes. Of course Im testing the functionality before I send message that its "done", but I really don't know why I can't see trivial bugs. Some time it looks like I didnt test anything, but its not true. Ive always had this problems but now its pain in the a.s. My question is very simple, what happened to me ;)? Ok, joke aside. What do you do to avoid simple mistakes? plzzz don't tell me to use TDD. The project is... legacy and Im really sick and tired to fix it and adding more bugs into it. best regards

  • What IDE(s) or editor(s) do companies like Google, Apple, IBM, etc. use?

    - by Pius
    Even though I have quite some experience in using various tools, I still can't make up my mind whether I prefer using IDE or a simple editor for code editing. Most IDEs I have experienced are written in Java (like Eclipse) which makes them slow and bulky. What's good about them is that it provides lots of tools. On the other hand editors are usually VERY fast. They can also be extended to become more similar to IDEs but usually I don't do that. However, there is Sublime Text 2 which has some basic code completion built-in. My question would be whether most Enterprise companies like Google, Apple, IBM and etc (except Microsoft because they have AMAZING IDE which, I assume, is used by MS developers) force their workers to use IDEs and whether using plain editor with external tools is considered being not professional? P.S. Not talking about cases like Android development where working without IDE barely possible.

  • WCF: WSDL-first approach: Problems with generating fault types

    - by Juri
    Hi, I'm currently in the process of creating a WCF webservice which should be compatible with WS-I Basic Profile 1.1. I'm using a wsdl-first approach (actually for the first time), defining first the xsd for the complex types, the WSDL and then using svcutil.exe for generating the according server as well as client-side interfaces/proxies. So far everything works fine. Then I decided to add a fault to my WSDL. Regenerating with svcutil succeeded, but then I noticed that my generated fault doesn't have the properties I defined in my xsd file (which is imported by my WSDL). Fault XSD definition <?xml version="1.0" encoding="UTF-8"?> <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://product.mycompany.com/groupsfault_v1.xsd" xmlns:tns="http://product.mycompany.com/groupsfault_v1.xsd"> <complexType name="groupsFault"> <sequence> <element name="code" type="int"/> <element name="message" type="string"/> </sequence> </complexType> </schema> Generated .Net fault object [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Xml.Serialization.XmlSchemaProviderAttribute("ExportSchema")] [System.Xml.Serialization.XmlRootAttribute(IsNullable=false)] public partial class groupFault : object, System.Xml.Serialization.IXmlSerializable { private System.Xml.XmlNode[] nodesField; private static System.Xml.XmlQualifiedName typeName = new System.Xml.XmlQualifiedName("groupFault", "http://sicp.services.siag.it/groups_v1.wsdl"); public System.Xml.XmlNode[] Nodes { get { return this.nodesField; } set { this.nodesField = value; } } public void ReadXml(System.Xml.XmlReader reader) { this.nodesField = System.Runtime.Serialization.XmlSerializableServices.ReadNodes(reader); } public void WriteXml(System.Xml.XmlWriter writer) { System.Runtime.Serialization.XmlSerializableServices.WriteNodes(writer, this.Nodes); } public System.Xml.Schema.XmlSchema GetSchema() { return null; } public static System.Xml.XmlQualifiedName ExportSchema(System.Xml.Schema.XmlSchemaSet schemas) { System.Runtime.Serialization.XmlSerializableServices.AddDefaultSchema(schemas, typeName); return typeName; } } Is this ok?? I'd expect to have an object created that contains properties for "code" and "message" s.t. you can then throw it by using something like ... throw new FaultException<groupFault>(new groupFault { code=100, message="error" }); ... (sorry for the lower-case type definitions, but this is generated code from the WSDL) Why doesn't the svcutil.exe generate those properties?? Some sources on the web suggested to add the /useSerializerForFaults option. I tried it, it doesn't work giving me an exception that the fault type is missing on the wsdl:portType declaration. Validation with several other tools succeeded however. Any help is VERY appreciated :) thx

  • a non recursive approach to the problem of generating combinations at fault

    - by mark
    Hi, I wanted a non recursive approach to the problem of generating combination of certain set of characters or numbers. So, given a subset k of numbers n, generate all the possible combination n!/k!(n-k)! The recursive method would give a combination, given the previous one combination. A non recursive method would generate a combination of a given value of loop index i. I approached the problem with this code: Tested with n = 4 and k = 3, and it works, but if I change k to a number 3 it does not work. Is it due to the fact that (n-k)! in case of n = 4 and k = 3 is 1. and if k 3 it will be more than 1? Thanks. int facto(int x); int len,fact,rem=0,pos=0; int str[7]; int avail[7]; str[0] = 1; str[1] = 2; str[2] = 3; str[3] = 4; str[4] = 5; str[5] = 6; str[6] = 7; int tot=facto(n) / facto(n-k) / facto(k); for (int i=0;i<tot;i++) { avail[0]=1; avail[1]=2; avail[2]=3; avail[3]=4; avail[4]=5; avail[5]=6; avail[6]=7; rem = facto(i+1)-1; cout<<rem+1<<". "; for(int j=len;j>0;j--) { int div = facto(j); pos = rem / div; rem = rem % div; cout<<avail[pos]<<" "; avail[pos]=avail[j]; } cout<<endl; } int facto(int x) { int fact=1; while(x0) fact*=x--; return fact; }

  • Analysing a Visual Foxpro application to derive requirements. Tools/approaches/practices?

    - by Kabeer
    Hello. In an upcoming project I am supposed to re-engineer a huge application built on Visual Foxpro into a web-application. The target platform is .Net. The application from the end-users' perspective is very complex (complex forms, reports, navigation, etc). The sorry state is that there are no documents available from which I can derive, business processes, business rules, work-flows, validations, application state, etc. I can gather some requirements from end-users but it cannot be complete from any perspective. Maneuvering through the code would be tedious & time consuming, given the millions of lines of code. Therefore I am looking for a tool that can help me in code analysis. My googling attempt didn't help me at least for a Visual Foxpro code base. Besides, I will appreciate if someone can share processes/approaches/techniques to establish the requirements as far as possible. BTW, this link didn't quite help.

  • Replicating MySQL DB to development machine - bad idea?

    - by Joel
    I am considering replicating a production MySQL database to my development machine so I've always got current data. The production database is externally hosted. My development machine is behind an unreliable internet connection. It is entirely possible that the development machine could be disconnected from the internet for extended periods of time (hours). Would there be any adverse effect on the production database by doing this? (I don't strictly need live data - but it would be nice, and good excuse to dabble with replication. If the consensus is that this is a bad idea, I'll set up a daily job to import the previous night's backup into my development database)

  • Is there a recommended approach to handle saving data in response to within-site navigation without

    - by Carvell Fenton
    Hello all, Preamble to scope my question: I have a web app (or site, this is an internal LAN site) that uses jQuery and AJAX extensively to dynamically load the content section of the UI in the browser. A user navigates the app using a navigation menu. Clicking an item in the navigation menu makes an AJAX call to php, and php then returns the content that is used to populate the central content section. One of the pages served back by php has a table form, set up like a spreadsheet, that the user enters values into. This table is always kept in sync with data in the database. So, when the table is created, is it populated with the relevant database data. Then when the user makes a change in a "cell", that change immediately is written back to the database so the table and database are always in sync. This approach was take to reassure users that the data they entered has been saved (long story...), and to alleviate them from having to click a save button of some kind. So, this always in sync idea is great, except that a user can enter a value in a cell, not take focus out of the cell, and then take any number of actions that would cause that last value to be lost: e.g. navigate to another section of the site via the navigation menu, log out of the app, close the browser, etc. End of preamble, on to the issue: I initially thought that wasn't a problem, because I would just track what data was "dirty" or not saved, and then in the onunload event I would do a final write to the database. Herein lies the rub: because of my clever (or not so clever, not sure) use of AJAX and dynamically loading the content section, the user never actually leaves the original url, or page, when the above actions are taken, with the exception of closing the browser. Therefore, the onunload event does not fire, and I am back to losing the last data again. My question, is there a recommended way to handle figuring out if a person is navigating away from a "section" of your app when content is dynamically loaded this way? I can come up with a solution I think, that involves globals and tracking the currently viewed page, but I thought I would check if there might be a more elegant solution out there, or a change I could make in my design, that would make this work. Thanks in advance as always!

  • help Implementing Object Oriented ansi-C approach??

    - by No Money
    Hey there, I am an Intermediate programmer in Java and know some of the basics in C++. I recently started to scam over "C language" [please note that i emphasized on C language and want to stick with C as i found it to be a perfect tool, so no need for suggestions focusing on why should i move back to C++ or Java]. Moving on, I code an Object Oriented approach in C but kindda scramble with the pointers part. Please understand that I am just a noob trying to extend my knowledge beyond what i learned in High School. Here is my code..... #include <stdio.h> typedef struct per{ int privateint; char *privateString; struct per (*New) (); void (*deleteperOBJ) (struct t_person *); void (*setperNumber) ((struct*) t_person,int); void (*setperString) ((struct*) t_person,char *); void (*dumpperState) ((struct*) t_person); }t_person; void setperNumber(t_person *const per,int num){ if(per==NULL) return; per->privateint=num; } void setperString(t_person *const per,char *string){ if(per==NULL) return; per->privateString=string; } void dumpperState(t_person *const per){ if(per==NULL) return; printf("value of private int==%d\n", per->privateint); printf("value of private string==%s\n", per->privateString); } void deleteperOBJ(struct t_person *const per){ free((void*)t_person->per); t_person ->per = NULL; } main(){ t_person *const per = (struct*) malloc(sizeof(t_person)); per = t_person -> struct per -> New(); per -> setperNumber (t_person *per, 123); per -> setperString(t_person *per, "No money"); dumpperState(t_person *per); deleteperOBJ(t_person *per); } Just to warn you, this program has several errors and since I am a beginner I couldn't help except to post this thread as a question. I am looking forward for assistance. Thanks in advance.

  • Best approach for using Scanner Objects in Java?

    - by devjeetroy
    Although I'm more of a C++/ASM guy, I have to work with java as a part of my undergrad course at college. Our teacher taught us input using Scanner(System.in), and told us that if multiple functions are were taking user input, it would be advisable that a single Scanner object is passed around so as to reduce chances of the input stream getting screwed up. Now using this approach has gotten me into a situation where I'm trying to use a Scanner.nextLine(), and this statement does not wait for user input. It just moves on to the following statement. I figured there may be some residual cr/lf or other characters in the Scanner that might not have been retrieved are causing the problem. Here is the code. while(lineScanner.hasNext()) { if(isPlaceHolder(temp = lineScanner.next())) { temp = temp.replace("<",""); temp = temp.replace(">", ""); System.out.print("Enter "+aOrA(temp.charAt(0)) +" " +temp + " : "); temp = consoleInput.nextLine(); } outputFileStream.print(temp + " "); } All of the code is inside a function which receives a Scanner object consoleInput. Ok, so what happens when i run it is that when the program enters the if() the first time, It carries out theSystem.out.print, does not wait for user input, and moves on to the second time that it enters the 'if' block. This time, it takes the input and the rest of the program operates normally. What is even more surprising is that when i check the output file created by the program, it is perfect, just as i want to be. Almost as if the first time input using the scanner is correct. I have solved this problem by creating a new system.in Scanner in the function itself, instead of receiving the Scanner object as a parameter. But I am still very curious to know what the hell is happening and why it couldn't be solved using a simple Scanner.reset(). Would it be better to just simply create a Scanner Object for each function? Thanks, Devjeet PS. Although I know how to take input using fileinputstreams and the like, we are not supposed to use it with the homework.

  • .NET Development of iPhone App with MonoTouch - which development environment?

    - by Click Ahead
    Hi All, I'm a .NET developer (C#) with several years developing Windows Mobile Apps. I would like to get into developing iPhone Apps and MonoTouch looks good based on reviews I've read. So I'm going to go with MonoTouch. My understanding is that I'll need a new Mac, but as it happens I also need a new PC for my .NET windows development. My question is should I (a) Purchase a Mac Book Pro and dual boot with Windows 7 (b) Purchase a Mac Pro and dual boot with Windows 7 (c) Purchase a good Dev PC and a slighlty less well spec'd Mac Book Pro or Mac Pro Bear in mind I'm only doing MonoTouch development with the Mac, most of my development (approx. 80% initially) will be done on the Windows side. My budget is approx. €3,000 / $4,000 and I'd like a good, fast development environment.It's purely for development so on the windows side installing SQL 2008/VS 2010/Office and on the OS X side installing MonoTouch. BTW - my budget excludes licensing for VS/MonoTouch/etc, I have a MonoTouch and MSDN license. Any opinions are greatly appreciated. I'm a newbie to Mac's !

  • Resolving the Access is Denied Error in VSeWSS Deployments

    - by Damon
    Visual Studio Extensions for Windows SharePoint Services 1.3 (VSeWSS 1.3) tends to make my life easier unless I'm typing out the words that make up the VSeWSS acronym - really, what a mouthful.  But one of the problems that I routinely encounter are error messages when trying to deploy solutions.  These normally look something like the following: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) I tried a variety of steps to resolve this issue: Recycling the application pool Restarting IIS Closing Visual Studio Not detaching from the debugger until a request was fully completed Logging off and logging back into Windows etc. Nothing actually worked.  Some of these resolution attempts seemed to help keep the problem from happening quite as frequently, but I still have no idea what EXACTLY causes the problem and it would rear its ugly head from time to time.  Unfortunately, the only resolution I found that seemed to work was to reboot the machine . which is a crappy resolution. Finally sick enough of the problem to spend some time on it, I went on a search and tried to figure out if anyone else was having this issue.  People seem to suggest that turning off the Indexing Service on your machine helps resolve this problem.  I tried turning it off but I kept having issues.  Which was depressing.  Fortunately, I stumbled upon the resolution when I was looking through the services list.  If you encounter the issue, all you have to do is reset the World Wide Web Publishing Service.  I've had a 100% success rate so far with this approach.  I'm not sure if having the Indexing Service is part of the solution, but I've kept it disabled for the time being because I'm really sick of having to reboot my machine to deal with that error message. If you do VSeWSS development, you may also want to check out this blog post: VSeWSS 1.3 - Getting around the "Unable to load one or more of the requested types" Error

  • How to push changes from Test server to Live server?

    - by anonymous
    As a beginner, I finally noticed the issue with making changes to the live server I've been working on, now that I have a couple users on it, since I bring it down so often. I created an EC2 image of my live server and set up a separate instance on EC2, so now I have 2 EC2 instances, Stage and Production. I set up GitHub and push changes to stage and test my code there, and when it's all done and working, I push it to the production branch, and everything is good. And there is a slight issue here since I name my files config_stage.js and config_production.js and set up .gitignore on each server, and in my code, I would have it read the ENV flags and set up the appropriate configs, is this the correct approach? And my main question is: how do you keep track of non-code changes to the server? For example, I installed HAProxy, Stunnel, Redis, MongoDB and several other things onto the Stage server for testing and now that it's all working and good, how do I deploy them to production? Right now, I'm just keeping track of everything I installed and copying configuration files over, which is very tedious and I'm afraid I may have missed a step somewhere. Is there a better way to port these changes over from my test server to my live server?
