• Is there such a thing as a super programmer? [closed]

  - by Muhammad Alkarouri

  Have you come across a super programmer? What identifies him or her as such, compared to "normal" experienced/great programmers? Also. how do you deal with a person in your team who believes he is a super programmer? Both in case he actually is or if he isn't? Edit: Interesting inputs all round, thanks. A few things can be gleaned: A few definitions emerged. Disregarding too localised definitions (that identified the authors or their acquaintance as super programmers), I liked a couple definitions: Thorbjørn's definition: a person who does the equivalent of a good team consistently for a long time. Free Electron, linked from Henry's answer. A very productive person, of exceptional abilities. The explanation is a good read. A Free Electron can do anything when it comes to code. They can write a complete application from scratch, learn a language in a weekend, and, most importantly, they can dive into a tremendous pile of spaghetti code, make sense of it, and actually getting it working. You can build an entire businesses around a Free Electron. They’re that good. Contrasting with the last definition, is the point linked to by James about the myth of the genius programmer (video). The same idea is expressed as egoless programming in rwong's comment. They present opposite opinions as whether to optimise for such a unique programmer or for a team. These definitions are definitely different, so I would appreciate it if you have an input as to which is better. Or add your own if you want of course, though it would help to say why it is different from those.

• There is No Scrum without Agile

  - by John K. Hines

  It's been interesting for me to dive a little deeper into Scrum after realizing how fragile its adoption can be.  I've been particularly impressed with James Shore's essay "Kaizen and Kaikaku" and the Net Objectives post "There are Better Alternatives to Scrum" by Alan Shalloway.  The bottom line: You can't execute Scrum well without being Agile. Personally, I'm the rare developer who has an interest in project management.  I think the methodology to deliver software is interesting, and that there are many roles whose job exists to make software development easier.  As a project lead I've seen Scrum deliver for disciplined, highly motivated teams with solid engineering practices.  It definitely made my job an order of magnitude easier.  As a developer I've experienced huge rewards from having a well-defined pipeline of tasks that were consistently delivered with high quality in short iterations.  In both of these cases Scrum was an addition to a fundamentally solid process and a huge benefit to the team. The question I'm now facing is how Scrum fits into organizations withot solid engineering practices.  The trend that concerns me is one of Scrum being mandated as the single development process across teams where it may not apply.  And we have to realize that Scurm itself isn't even a development process.  This is what worries me the most - the assumption that Scrum on its own increases developer efficiency when it is essentially an exercise in project management. Jim's essay quotes Tobias Mayer writing, "Scrum is a framework for surfacing organizational dysfunction."  I'm unsure whether a Vice President of Software Development wants to hear that, reality nonwithstanding.  Our Scrum adoption has surfaced a great deal of dysfunction, but I feel the original assumption was that we would experience increased efficiency.  It's starting to feel like a blended approach - Agile/XP techniques for developers, Scrum for project managers - may be a better fit.  Or at least, a better way of framing the conversation. The blended approach. Technorati tags: Agile Scrum

• How much knowledge do I need to begin a project in Django

  - by Smock

  I started learning django about a month ago. I have an intermediate C, Java programming experience. I read the first 8 chapters of the django book . Afterwards, I picked up Practical Django Projects by James Bennett and did the first two projects: CMS & Web Blog. Although, I started getting lost when he got to the generic views part. I know that's important but I'm not sure how important that is when trying to implement a project. Anyway, I have a project in mind that I'd like to start; however, I'm nervous as to where to begin. I'm overwhelmed with the number of things that I'd like my project to do but no knowledge or minimal knowledge as to how e.g. how do i implement css and javascript in my project. Moreover, I am aware that some django packages exists to ease development but I don't know if I should use them or not. Anyway, I apologize for my length message. I just want some advice/encouragement. I have a project in mind but do you think I need to read more materials/tutorials or is it smart to just start working on my project based on the minimal knowledge i've gained from those books? Any information that can be provided is much appreciated. I really want to get good at this but I just need some direction.

• Integrated Reporting is Getting Closer

  - by jmorourke

  Oracle recently sponsored a webcast on CFO.com titled:  The CFO Playbook on Integrated Reporting: Integrating Sustainability into Financial Disclosures.  The speakers for this webcast were James Margolis, partner with Environmental Resources Management (ERM), a global provider of environmental, health, safety, risk and sustainability consulting services (EHSS) and Mike Wallace, Director of the Global Reporting Initiative's Focal Point USA. This webcast focused on why top companies in the U.S. and overseas are incorporating sustainability content into their annual reports and other financial disclosures. The speakers discussed the benefits of integrating sustainability reporting with traditional financial reporting. They noted how investors, corporate directors, lenders and most recently, the Securities and Exchange Commission, use this information to better understand, benchmark and value companies. They also discussed the November 2012 release of an Integrated Reporting Framework by the International Integrated Reporting Council (IIRC).  See the press release and link to the framework here.  The shift towards integrated financial and sustainability reporting is gaining momentum with a number of global stock exchanges endorsing this approach in 2012.  See the links here if you want to listen to the webcast or download the slides. Also, here is a demonstration of Oracle’s solution for integrated financial and sustainability reporting.

• Large enterprise application - clients wish to use duplicate e-mails addresses?

  - by Alex Key

  I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: [email protected] James Jeffery: [email protected] Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

• Investigating Strategies For Functional Decomposition

  - by Liam McLennan

  Introducing Functional Decomposition Before I begin I must apologise. I think I am using the term ‘functional decomposition’ loosely, and probably incorrectly. For the purpose of this article I use functional decomposition to mean the recursive splitting of a large problem into increasingly smaller ones, so that the one large problem may be solved by solving a set of smaller problems. The justification for functional decomposition is that the decomposed problem is more easily solved. As software developers we recognise that the smaller pieces are more easily tested, since they do less and are more cohesive. Functional decomposition is important to all scientific pursuits. Once we understand natural selection we can start to look for humanities ancestral species, once we understand the big bang we can trace our expanding universe back to its origin. Isaac Newton acknowledged the compositional nature of his scientific achievements: If I have seen further than others, it is by standing upon the shoulders of giants   The Two Strategies For Functional Decomposition of Computer Programs Private Methods When I was working on my undergraduate degree I was taught to functionally decompose problems by using private methods. Consider the problem of painting a house. The obvious solution is to solve the problem as a single unit: public void PaintAHouse() { // all the things required to paint a house ... } We decompose the problem by breaking it into parts: public void PaintAHouse() { PaintUndercoat(); PaintTopcoat(); } private void PaintUndercoat() { // everything required to paint the undercoat } private void PaintTopcoat() { // everything required to paint the topcoat } The problem can be recursively decomposed until a sufficiently granular level of detail is reached: public void PaintAHouse() { PaintUndercoat(); PaintTopcoat(); } private void PaintUndercoat() { prepareSurface(); fetchUndercoat(); paintUndercoat(); } private void PaintTopcoat() { fetchPaint(); paintTopcoat(); } According to Wikipedia, at least one computer programmer has referred to this process as “the art of subroutining”. The practical issues that I have encountered when using private methods for decomposition are: To preserve the top level API all of the steps must be private. This means that they can’t easily be tested. The private methods often have little cohesion except that they form part of the same solution. Decomposing to Classes The alternative is to decompose large problems into multiple classes, effectively using a class instead of each private method. The API delegates to related classes, so the API is not polluted by the sub-steps of the problem, and the steps can be easily tested because they are each in their own highly cohesive class. Additionally, I think that this technique facilitates better adherence to the Single Responsibility Principle, since each class can be decomposed until it has precisely one responsibility. Revisiting my previous example using class composition: public class HousePainter { private undercoatPainter = new UndercoatPainter(); private topcoatPainter = new TopcoatPainter(); public void PaintAHouse() { undercoatPainter.Paint(); topcoatPainter.Paint(); } } Summary When decomposing a problem there is more than one way to represent the sub-problems. Using private methods keeps the logic in one place and prevents a proliferation of classes (thereby following the four rules of simple design) but the class decomposition is more easily testable and more compatible with the Single Responsibility Principle.

• Three New Videos on Social Development

  - by Bob Rhubart

  By now it should be clear to even the most tenacious Luddite that the social media phenomenon is no mere fad. Those ubiquitous icons for Facebook and Twitter and other social networks are little beacons of disruptive change signalling yet again that the 20th century is over, dude. And that presents an opportunity for software developers with the necessary insight and expertise to tap into and expand social platforms for forward-thinking organizations. If you're a developer and you're interested in exploiting these emerging opportunities you'll want to check out three new videos that focus on software development for social platforms. Developing with Facebook: An Introduction to Social Design James Pearce, Facebook's head of Mobile Developer Relations, provides an overview of the Facebook platform and the underlying APIs that are available to the developer community. Building on the LinkedIn Platform: Content Amplified Adam Trachtenberg, Director of LinkedIn's Developer Network, discusses how you can make it simple for a professional audience to discover and distribute your content on LinkedIn. Emergence of the Social Enterprise Roland Smart, Oracle's VP of Social Marketing, shares Oracle’s vision for the social-enabled enterprise and highlights the role developers will play in the next phase of enterprise development. OTN has also created the Oracle Social Developer Community, a new Facebook page devoted to the promotion of community conversation and resources to support Social Developers. If you're working on a social development project, visit the page and tell us about it.

• SQL language drawbacks, The Third Manifesto

  - by David Portabella

  Sometime ago I read about SQL language drawbacks (the basic language specification, not vendor specific), and one of the drawbacks was that the language does not allow to create a set of tuples that don't come from a table. For instance, SELECT firstName, lastName from people; this creates a set of tuples coming from the table people. Now, if I don't have this table people, and I want to return a constant, I'd need something like this to return a set of two tuples (this would not require to have a table): SELECT VALUES('james', 'dean'), ('tom', 'cruisse'); Why I would need that? Because of the same reasons that we can define constants (not only basic types, but objects and arrays also) in any advanced programming language. Workarounds, Yes, I could create a temporal table, fill the data, and SELECT from that table. This is a hack, to overcome the drawbacks of the poor SQL language. I think that I read about this somewhere in "The Third Manifesto", but I don't find the paragraph/example talking about this concrete drawback anymore. Do you know a reference about it?

• How to restrict HTTP Methods

  - by hemalshah

  How can I restrict HTTP methods to those required by the MOSS07 application(s) using IIS6? Update This is what was written in the document IIS6 should be used to restrict HTTP methods to those required by the MOSS07 application(s). I also searched some books and saw something curious in O'Reilly's Sharepoint 2007 by James Pyles and others. There is no real suppported way to use HTTP POST and HTTP GET because of the web.config settings and the static definition of the WSDL. In the web.config <protocols> <remove name="HttpGet"> <remove name="HttpPost"> <remove name="HttpPostLocalHost"> <add name="Documentation"> </protocols> If we do this in the Web.Config file, would it solve the problem?

• Why is my spawned process still causing IntelliJ to wait?

  - by itsadok

  I'm trying to start a server as part of an Ant artifact. Here are the relevant lines: <exec dir="." executable="cmd.exe" spawn="true"> <arg line="/c c:\Java\james-2.3.2\bin\debug.bat" /> </exec> If I start it with ant from the command line, a process is spawned and I get a command prompt and everything seems fine. However, if I start it from IntelliJ 6, my IDE, the build stays alive until I kill the server. Here's the line IntelliJ uses to start ant: C:\Java\jdk1.6.0_02\bin\java -Xmx128m -Dant.home=C:\Java\apache-ant-1.7.1 -Dfile.encoding=UTF-8 -classpath "C:\Java\apache-ant-1.7.1\lib\ant-antlr.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-bcel.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-bsf.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-log4j.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-oro.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-regexp.jar;C:\Java\apache-ant-1.7.1\lib\ant-apache-resolver.jar;C:\Java\apache-ant-1.7.1\lib\ant-commons-logging.jar;C:\Java\apache-ant-1.7.1\lib\ant-commons-net.jar;C:\Java\apache-ant-1.7.1\lib\ant-jai.jar;C:\Java\apache-ant-1.7.1\lib\ant-javamail.jar;C:\Java\apache-ant-1.7.1\lib\ant-jdepend.jar;C:\Java\apache-ant-1.7.1\lib\ant-jmf.jar;C:\Java\apache-ant-1.7.1\lib\ant-jsch.jar;C:\Java\apache-ant-1.7.1\lib\ant-junit.jar;C:\Java\apache-ant-1.7.1\lib\ant-launcher.jar;C:\Java\apache-ant-1.7.1\lib\ant-netrexx.jar;C:\Java\apache-ant-1.7.1\lib\ant-nodeps.jar;C:\Java\apache-ant-1.7.1\lib\ant-starteam.jar;C:\Java\apache-ant-1.7.1\lib\ant-stylebook.jar;C:\Java\apache-ant-1.7.1\lib\ant-swing.jar;C:\Java\apache-ant-1.7.1\lib\ant-testutil.jar;C:\Java\apache-ant-1.7.1\lib\ant-trax.jar;C:\Java\apache-ant-1.7.1\lib\ant-weblogic.jar;C:\Java\apache-ant-1.7.1\lib\ant.jar;C:\Java\apache-ant-1.7.1\lib\xercesImpl.jar;C:\Java\apache-ant-1.7.1\lib\xml-apis.jar;C:\Java\jdk1.6.0_02\lib\tools.jar;C:\Program Files\JetBrains\IntelliJ IDEA 6.0\lib\idea_rt.jar" com.intellij.rt.ant.execution.AntMain2 -logger com.intellij.rt.ant.execution.IdeaAntLogger2 -inputhandler com.intellij.rt.ant.execution.IdeaInputHandler -buildfile C:\Java\Projects\CcMailer\ccmailer.xml jar I suspect the inputhandler parameter has something to do with the problem, but if I run it myself the problem is not reproduced. Either way, I have only limited control over what IntelliJ does. My question is: how does IntelliJ even know the process is running? The Ant process is long gone. Is there a way to start a subprocess in a more sneaky way, so that IntelliJ won't even know there's anything to wait around for? Here's what I've tried so far: I tried using the start command, like this: <exec dir="." executable="cmd.exe" spawn="true"> <arg line="/c start cmd /c c:\Java\james-2.3.2\bin\debug.bat" /> </exec> I also tried using python, with code like this: import os.path import subprocess subprocess.Popen(["cmd.exe", "/c", "debug.bat"], stdin=open(os.path.devnull), stdout=open(os.path.devnull, "w"), stderr=subprocess.STDOUT) To no avail. The build window always stays up until I kill the server. Any ideas?

• How do people know so much about programming?

  - by Luciano

  I see people in this forums with a lot of points, so I assume they know about a lot of different programming stuff. When I was young I knew about basic (commodore) and the turbo pascal (pc). Then in college I learnt about C, memory management, x86 set, loop invariants, graphs, db query optimization, oop, functional, lambda calculus, prolog, concurrency, polymorphism, newton method, simplex, backtracking, dynamic programming, heuristics, np completeness, LR, LALR, neural networks, static & dynamic typing, turing, godel, and more in between. Then in industry I started with Java several years ago and learnt about it, and its variety of frameworks, and also design patterns, architecture patterns, web development, server development, mobile development, tdd, bdd, uml, use cases, bug trackers, process management, people management if you are a tech lead, profiling, security concerns, etc. I started to forget what I learnt in college... And then there is the stuff I don't know yet, like python, .net, perl, JVM stuff like groovy or scala.. Of course Google is a must for rapid documentation access to know if a problem has been solved already and how, and to keep informed about new stuff by blogs and places like this one. It's just too much or I just have a bad memory.. how do you guys manage it?

• Computing unique index for every poker starting hand

  - by Aly

  As there are 52 cards in a deck we know there are 52 choose 2 = 1326 distinct matchups, however in preflop poker this can be bucketed into 169 different hands such as AK offsuit and AK suited as whether it is A hearts K hearts or A spade K spades it makes no difference preflop. My question is, is there a nice mathematical property in which I can uniquely index each of these 169 hands (from 0 to 168 preferably). I am trying to create a look up table as a double[][] = new double [169][169] but have no way of changing a hand representation such as AKs (an Ace and a King of the same suit) to a unique index in this array.

One problem (two if you count not being in a financial position to slap down $1000+ for a mac) ; I am a PC head, specifically a Linux-head, and have no regular access to a Mac platform to develop on. I cannot see any way of getting my hands on iSDK without being on a Mac, (but have been known to be wrong) How hopeless is my plight and where can I go from here?

• Load balancing and shedulling algorithms .NET

  - 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 approx. each job will take to be caclulated. Also I have priorities. My question is how to keep all machines loaded 99-100% and shedule the jobs in the best way. Each machine can do several calculations at the time. Jobs are pushed to the machine. Central machine knows current load of each machine. Also I would like to to assign some king of machine learning here, because I will know statistics of each job (started, finished, cpu load etc.). How to distribute jobs(calculations) in the best possible way, also keep in mind priority. Any suggestions ? Ideas ? Algorithms ?

• XML Schema Header & Namespace Config

  - by zharvey

  Migrating from DTD to XSD and for some reason the transition is a bumpy one. I understand how to define the schema once I'm inside the <xs:schema> root tag, but getting past the header & namespace declaration stuff is proving to be especially confusing for me. I have been trying to follow the well-laid out tutorial on W3S but even that tutorial seems to assume a lot of knowledge up front. I guess what I'm looking for is a King's English explanation of which attributes do what, where they go, and why: xmlns xmlns:xs xmlns:xsi targetNamespace xsi:schemaLocation And in some cases I see different variations of these elements/attributes, such as xsi which seems to have two different notations like xsi:schemaLocation="..." and xs:import schemaLocation="...". I guess between all these slight variations I can't seem to make heads or tails of what each of these does. Thanks in advance for bringing any clarity to this confusion!

• JAXB Annotated class - setting of a variable which is not an element

  - by sswdeveloper

  I have a JAXB annotated class say @XmlRootElement(namespace = "http://www.abc.com/customer") Class Customer{ @XmlElement(namespace = "http://www.abc.com/customer") private String Name; @XmlElement(namespace = "http://www.abc.com/customer") private String Address; @XmlTransient private HashSet set = new HashSet(); public String getName(){ return Name; } public void setName(String name){ this.Name = name; set.add("Name"); } public String getAddress(){ return Address; } public void setAddress(String address){ this.Address = address; set.add("Address"); } public void getSet(){ return set; } I have a XML of the form <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Customer xmlns="http://www.abc.com/customer" > <Name>Ralph</Name> <Address>Newton Street</Address> </Customer> I use JAXB unmarshalling to get the object representation of the XML input. The values for Name and Address are set correctly. However the value of set gets lost(since it is @XMLTransient it gets ignored) Is there any way of ensuring that it is still set in the object which has been unmarshalled? Some other annotation which I can use?
