  • How to increase the bus factor and specialize at the same time?

    - by bizso09
    In agile pair programming it is recommended to switch pairs every now and then so as to increase the bus factor of the team. That means, most people in the team should work on different parts of the system at different times so that everyone has an understanding of it. Now it is impssible that everyone has an expert level of understanding of each part of the system. That's because people are urged to specialize in one area of expertise. If you are an expert database admin, what's the point of working on the user interface of the system when you switch pairs? You will not be able to do such a high quality job as someone who has extensive experience in UI design. How can you increase the bus factor and make sure that you have specialization in your team?

  • C# Open Source software that is useful for learning Design Patterns

    - by Fathom Savvy
    In college I took a class in Expert Systems. The language the book taught (CLIPS) was esoteric - Expert Systems: Principles and Programming, Fourth Edition. I remember having a tough time with it. So, after almost failing the class, I needed to create the most awesome Expert System for my final presentation. I chose to create an expert system that would calculate risk analysis for a person's retirement portfolio. In short, the system would provide the services normally performed by one's financial adviser. In other words, based on personality, age, state of the macro economy, and other factors, should one's portfolio be conservative, moderate, or aggressive? In the appendix of the book (or on the CD-ROM), there was this in-depth example program for something unrelated to my presentation. Over my break, I read and re-read every line of that program until I understood it to the letter. Even though it was unrelated, I learned more than I ever could by reading all of the chapters. My presentation turned out to be pretty damn good and I received praises from my professor and classmates. So, the moral of the story is..., by understanding other people's code, you can gain greater insight into a language/paradigm than by reading canonical examples. Still, to this day, I am having trouble with everyday design patterns such as the Factory Pattern. I would like to know if anyone could recommend open source software that would help me understand the Gang of Four design patterns, at the very least. I have read the books, but I'm having trouble writing code for the concepts in the real world. Perhaps, by studying code used in today's real world applications, it might just "click". I realize a piece of software may only implement one kind of design pattern. But, if the pattern is an implementation you think is good for learning, and you know what pattern to look for within the source, I'm hoping you can tell me about it. For example, the System.Linq.Expressions namespace has a good example of the Visitor Pattern. The client calls Expression.Accept(new ExpressionVisitor()), which calls ExpressionVisitor (VisitExtension), which calls back to Expression (VisitChildren), which then calls Expression (Accept) again - wooah, kinda convoluted. The point to note here is that VisitChildren is a virtual method. Both Expression and those classes derived from Expression can implement the VisitChildren method any way they want. This means that one type of Expression can run code that is completely different from another type of derived Expression, even though the ExpressionVisitor class is the same in the Accept method. (As a side note Expression.Accept is also virtual). In the end, the code provides a real world example that you won't get in any book because it's kinda confusing. To summarize, If you know of any open source software that uses a design pattern implementation you were impressed by, please list it here. I'm sure it will help many others besides just me. public class VisitorPatternTest { public void Main() { Expression normalExpr = new Expression(); normalExpr.Accept(new ExpressionVisitor()); Expression binExpr = new BinaryExpression(); binExpr.Accept(new ExpressionVisitor()); } } public class Expression { protected internal virtual Expression Accept(ExpressionVisitor visitor) { return visitor.VisitExtension(this); } protected internal virtual Expression VisitChildren(ExpressionVisitor visitor) { if (!this.CanReduce) { throw Error.MustBeReducible(); } return visitor.Visit(this.ReduceAndCheck()); } public virtual Expression Visit(Expression node) { if (node != null) { return node.Accept(this); } return null; } public Expression ReduceAndCheck() { if (!this.CanReduce) { throw Error.MustBeReducible(); } Expression expression = this.Reduce(); if ((expression == null) || (expression == this)) { throw Error.MustReduceToDifferent(); } if (!TypeUtils.AreReferenceAssignable(this.Type, expression.Type)) { throw Error.ReducedNotCompatible(); } return expression; } } public class BinaryExpression : Expression { protected internal override Expression Accept(ExpressionVisitor visitor) { return visitor.VisitBinary(this); } protected internal override Expression VisitChildren(ExpressionVisitor visitor) { return CreateDummyExpression(); } protected internal Expression CreateDummyExpression() { Expression dummy = new Expression(); return dummy; } } public class ExpressionVisitor { public virtual Expression Visit(Expression node) { if (node != null) { return node.Accept(this); } return null; } protected internal virtual Expression VisitExtension(Expression node) { return node.VisitChildren(this); } protected internal virtual Expression VisitBinary(BinaryExpression node) { return ValidateBinary(node, node.Update(this.Visit(node.Left), this.VisitAndConvert<LambdaExpression>(node.Conversion, "VisitBinary"), this.Visit(node.Right))); } }

  • How to properly express programming proficiency in CV?

    - by Pouya
    I'm rewriting my CV and I have a very hard time to express my programming skills in an honest matter while not underrating myself. How would you classify programming skill in four or five levels from complete beginner to god-like? For sake of argument, let us consider C++. What words would you use to present your programming skills? For example who is an expert in C++ or which word has a higher impact: Expert vs. Experienced? Could you suggest me 5 words like above in ascending order? P.S. I was planning to ask this question in Academia.SE, however, at the end I realized that I want to know programmers answer to the question.

  • DRIconf in Ubuntu 64x plus ATI GPU or something more?

    - by Balask
    I've been trying to get Call of Duty 2 to work in Wine in Ubuntu. It gives me a black screen. So I tried the fix suggested by the wine apphq and downloaded DRIconf. Funny thing is that it can't find my direct rendering device. "Could not detect any configurable direct-rendering capable devices. DRIconf will be started in expert mode" When I enter into it in Expert Mode is just errors out anyway. fglrxinfo gives me: display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11627 Compatibility Profile Context That shows me my driver is installed correctl,y right? World of Goo which is Linux native and requires direct rendering works like a charm. So I'm wondering, is there some other workaround? Is there a bigger issue? Does me running 64-bit affect it at all?

  • Pure sine wave inverter

    - by Nick
    Not exactly programming (sorry) but I think it's pretty close and can be of interest to other programmers. I'm trying to setup a battery power station so that I can work from anywhere. I go surfing a lot and my idea is to be able to work from wherever I can park my car (given there's coverage). So, I'm getting a deep cycle battery, a 240V charger (I'm in Australia), and an inverter. At the back of my laptop it says 19V and 4.62A. From the people I've spoken to that means it consumes about 90W at most. So my inverter needs to be able to output about 100W. Most of them seem to be 200W and up so this shouldn't be a problem. I want to be able run my laptop for 10 hours (plus the 2 hours I get from the laptop battery) straight. According to the people I've spoken to and from what I gather online I need a battery that has the amp hours for my "amp draw". I have no idea how to calculate this but I've been guesstimating. Most deep cycle batteries seem to be classified using amp hours (Ah)... 35Ah, 50Ah, 75Ah, 100Ah, and so on. However the amp hours on those batteries is for a 240V and I seem to be using 19V. According to an expert I spoke to you'd need a 100Ah battery to power a 5A appliance at 240V for 10 hours (you only get about 50% useful power). That to me is 5A * 240V = 100Ah battery. So, naive as I might be I take 240V and divide that by my 19V and reach the conclusion that I can get away with a battery that's about 12 times smaller than that 100Ah. The expert told me I needed a 50Ah battery so that's probably what I'll be getting, but it would be interesting to know what I theoretically would need to power my laptop for 10 hours. As for charging the battery the expert I spoke to said I needed a 3-5A charger to be able to charge that 50Ah battery from flat to full in about 10 hours (I will just leave it plugged in over night). Now to my question. The expert said it's not a matter of "if" more like a guaranteed "when" my computer will stuff up if I don't use a "pure sine wave inverter". From what I gather the power that comes out of that battery is not as clean as the power we get in the socket at home. Apparently it's "square" and the one in the socket is nice and smooth. I've already got an inverter, but it's not "pure". Do I really need to buy the $200-300 pure sine wave inverter or can I get away with something else? Perhaps the laptop adapter that sits in the middle of my laptop power cable already fixes that wave to be nice and smooth? Thanks!

  • OWB 11gR2 - Find and Search Metadata in Designer

    - by David Allan
    Here are some tools and techniques for finding objects, specifically in the design repository. There are ways of navigating and collating objects that are useful for day to day development and build-time usage - this includes features out of the box and utilities constructed on top. There are a variety of techniques to navigate and find objects in the repository, the first 3 are out of the box, the 4th is an expert utility. Navigating by the tree, grouping by project and module - ok if you are aware of the exact module/folder that objects reside in. The structure panel is a useful way of finding parts of an object, especially when large rather than using the canvas. In large scale projects it helps to have accelerators (either find or collections below). Advanced find to search by name - 11gR2 included a find capability specifically for large scale projects. There were improvements in both the tree search and the object editors (including highlighting in mapping for example). So you can now do regular expression based search and quickly navigate to objects within a repository. Collections - logically organize your objects into virtual folders by shortcutting the actual objects. This is useful for a range of things since all the OWB services operate on collections too (export/import, validation, deployment). See the post here for new collection functionality in 11gR2. Reports for searching by type, updated on, updated by etc. Useful for activities such as periodic incremental actions (deploy all mappings changed in the past week). The report style view is useful since I can quickly see who changed what and when. You can see all the audit details for objects within each objects property inspector, but its useful to just get all objects changed today or example, all objects changed since my last build etc. This utility combines both UI extensions via experts and the public views on the repository. In the figure to the right you see the contextual option 'Object Search' which invokes the utility, you can see I have quite a number of modules within my project. Figure out all the potential objects which have been changed is not simple. The utility is an expert which provides this kind of search capability. The utility provides a report of the objects in the design repository which satisfy some filter criteria. The type of criteria includes; objects updated in the last n days optionally filter the objects updated by user filter the user by project and by type (table/mappings etc.) The search dialog appears with these options, you can multi-select the object types, so for example you can select TABLE and MAPPING. Its also possible to search across projects if need be. If you have multiple users using the repository you can define the OWB user name in the 'Updated by' property to restrict the report to just that user also. Finally there is a search name that will be used for some of the options such as building a collection - this name is used for the collection to be built. In the example I have done, I've just searched my project for all process flows and mappings that users have updated in the last 7 days. The results of the query are returned in a table containing the object names, types, full path and audit details. The columns are sort-able, you can sort the results by name, type, path etc. One of the cool things here, is that you can then perform operations on these objects - such as edit them, export single selection or entire results to MDL, create a collection from the results (now you have a saved set of references in the repository, you could do deploy/export etc.), create a deployment script from the results...or even add in your own ideas! You see from this that you can do bulk operations on sets of objects based on search results. So for example selecting the 'Build Collection' option creates a collection with all of the objects from my search, you can subsequently deploy/generate/maintain this collection of objects. Under the hood of the expert if just basic OMB commands from the product and the use of the public views on the design repository. You can see how easy it is to build up macro-like capabilities that will help you do day-to-day as well as build like tasks on sets of objects.

  • The Java Community Process: What's Broken and How to Fix It

    - by Tori Wieldt
    In a panel discussion today at TheServerSide Java Symposium, Patrick Curran, Head of the Java Community Process, James Gosling, and ?Reza Rahman, member, Java EE 6 and EJB 3.1 expert groups, discussed the state of the JCP. Moderated by Cameron McKenzie, Editor of TheServerSide.com, they discussed what's wrong with JCP and ways to fix it.What's wrong with the JCP? Reza Rahman was quite supportive of the JCP. "I work as a consultant, and it's much better than getting a decision made a large company," Reza commented. He gave the JCP "Five stars" and explained that as an individual, he was able to have an impact on things that mattered to him. Cameron asked, "Now all these JCP problems came after Oracle acquired Sun, right?" To which the crowd had a good laugh, and the panel all agreed many of the JCP problems existed under Sun. How is the JCP handled differently under Oracle than Sun? "Pretty similar," said James. Oracle "tends more towards practicality" said Reza. "I'm glad to see things moving again, we've got several new JSRs filed," Patrick commented.How to Fix It?They all agreed greater transparency is a top issue. Without it, people assume sinister behavior whether it's there or not. Patrick said that currently spec leads are "encouraged" to be transparent, and the JCP office is planning to submit JSRs to change the JCP process so transparency is mandated, both for mailing lists and issue tracking. Shining a light on problems is the best way to fix them.Reza said the biggest problem is lack of a participation from the community. If more people are involved, a lot of the problems go away. "Developers are too non-chalant, they should realize what happens in the JCP has an direct impact on their career and they need to get involved." Reza commented.Got Involved!During Q&A, someone asked how a developer could get involved. They answered: Pick a JSR you are interested in and follow it. To start, you could read an article about the JSR and comment on the article (expert group members do read the comments). Or read the spec, discuss it with others and post a blog about it. Read the Expert Group proceedings. Join the JCP (free for individuals). Open source projects have code that you can download and play with, download it and provide feedback. Patrick mentioned that the JCP really wants more participation. "One way we are working on it is that we are encouraging JUGs to join the JCP as a group, and that makes all members of the JUG JCP members," Patrick said.They commented that most spec leads are desperate for feedback. "And, please get involved BEFORE the spec is finalized!" James declared. Someone from the audience said it's hard to put valuable time into something before it's baked. Patrick explained that Post Final Draft (PFD) is the time in the JCP process when the spec is mature enough to review but before the spec is finalized. The panel agreed the worst thing that could happen is that most people in the Java community just complain about the JCP without getting involved. Developer Sumit Goyal, conference attendee, thought it was a healthy discussion. "I got insights into how JSRs are worked on and finalized," he said.Key LinksThe Java Community Process Website  http://jcp.org/en/home/indexArticle: A Conversation with JCP Chair Patrick Curran Oracle Technology Network http://www.oracle.com/technetwork/java/index.htmlTheServerSide Java Symposium  http://javasymposium.techtarget.com/

  • Undetected Virus? I study at College, and Now all of the school computers have paint.exe -autocheck

    - by Jeffy
    "C:\WINDOWS\system32\Paint.exe" -autocheck is added to the registry every time its removed. This is like global. All the lab PCs(more than a hundred), personal laptops have this file. I really have no expert help to turn to.. as jotti says this file is clean. Here's the dropped file [removed] It seems that we all had this game cheating tool on our PCs called "Garena Maphack". Everytime it was run it would drop paint.exe into the system dir. Paint.exe is diguised as the real paint.exe from windows. Having the same icon and such. Check out threat expert's report at threatexpert.com/report.aspx?md5=176288f6f22a80c76329853f8535d45b The game cheat that started this huge mess can be obtained from [removed] What do I do? any experts care to take apart this file?

  • SQL SERVER – FIX: ERROR Msg 5169, Level 16: FILEGROWTH cannot be greater than MAXSIZE for file

    - by pinaldave
    I am writing this blog post right after I resolve this error for one of the system. Recently one of the my friend who is expert in infrastructure as well private cloud was working on SQL Server installation. Please note he is seriously expert in what he does but he has never worked SQL Server before and have absolutely no experience with its installation. He was modifying database file and keep on getting following error. As soon as he saw me he asked me where is the maxfile size setting so he can change. Let us quickly re-create the scenario he was facing. Error Message: Msg 5169, Level 16, State 1, Line 1 FILEGROWTH cannot be greater than MAXSIZE for file ‘NewDB’. Creating Scenario: CREATE DATABASE [NewDB] ON PRIMARY (NAME = N'NewDB', FILENAME = N'D:\NewDB.mdf' , SIZE = 4096KB, FILEGROWTH = 1024KB, MAXSIZE = 4096KB) LOG ON (NAME = N'NewDB_log', FILENAME = N'D:\NewDB_log.ldf', SIZE = 1024KB, FILEGROWTH = 10%) GO Now let us see what exact command was creating error for him. USE [master] GO ALTER DATABASE [NewDB] MODIFY FILE ( NAME = N'NewDB', FILEGROWTH = 1024MB ) GO Workaround / Fix / Solution: The reason for the error is very simple. He was trying to modify the filegrowth to much higher value than the maximum file size specified for the database. There are two way we can fix it. Method 1: Reduces the filegrowth to lower value than maxsize of file USE [master] GO ALTER DATABASE [NewDB] MODIFY FILE ( NAME = N'NewDB', FILEGROWTH = 1024KB ) GO Method 2: Increase maxsize of file so it is greater than new filegrowth USE [master] GO ALTER DATABASE [NewDB] MODIFY FILE ( NAME = N'NewDB', FILEGROWTH = 1024MB, MAXSIZE = 4096MB) GO I think this blog post will help everybody who is facing similar issues.

  • Receiving an MVP Award and Credibility

    - by Joe Mayo
    The post titled, The Problem with MVPs, by Steve Barbour was interesting because it makes you think about the thousands of MVPs around the world and what their value really is. Having been the recipient of multiple MVP awards, it’s an opportunity to reflect and judge my own performance. This is not a dangerous thing to do, but quite the opposite. If a person believes in self improvement, then critical analysis is an important part of that process. A lot of MVPs will tell you that they would be doing the same thing, regardless of whether they were an MVP or not; helping others in the community, which is also where I prefer to hang my hat. I’ve never defined myself as an expert and never will; this determination is left to others. In fact, let me just come out and say it, “I don’t know everything”. Shocked? Sometimes the gap between expectations and reality extends beyond a reasonable measure. Being labeled as a technical expert feels good for one's self esteem and is certainly a useful motivational technique. A problem can emerge though when an individual believes, too much, in what they are told. The problem is not with a pat on the back, but with a person does with the positive reinforcement. Is narcissism too strong a word? How often have you been in a public forum reading a demeaning response to a question that only serves in attempt to raise the stature of the person providing the response? Such behavior compromises one’s credibility, raises questions about validity of the MVP award, and is limited in community value. I’m currently under consideration for another MVP award on April 1st. If it happens, it will be good. Otherwise, I’ll keep writing articles, coding open source software, and whatever else I enjoy doing; with the best reward being that people find value in what I do.

"However, enterprise IT is reluctant to move data to public clouds, citing the tried-and-true excuses of security, privacy, and compliance. Although some have valid points, their reasons often boil down to 'I don't wanna.'"

This gives your fine-grained control over the configuration and behavior of components running within the virtual machine directly from Oracle VM Manager. You now have the ability to see and direct what goes on inside your VM from Oracle VM Manager. Get a reporting on IP addressing Use the template configuration facility to automatically configure virtual machines as they are first started Send messages directly to a virtual machine to trigger programmed events Query a virtual machine to obtain information pertaining to previous messages Enough of the theory! To get hands-on how-to’s and talk directly with the product expert on Oracle VM Guest Additions, Robbie de Meyer, or Oracle VM Templates for Oracle Database and RAC Template expert Saar Maoz, join us for the Oct 24th live webcast.

This series of article is written by Melanie Caffrey who is a senior development manager at Oracle. She is a coauthor of Expert PL/SQL Practices for Oracle Developers and DBAs (Apress, 2011) and Expert Oracle Practices: Oracle Database Administration from the Oak Table (Apress, 2010). The four articles are under the banner "Technology: SQL 101" and parts 9, 10, 11 and 12 cover SQL analytics. Here are the links to the four articles: Jan 2013 Having Sums, Averages, and Other Grouped Data March 2013 A Window into the World of Analytic Functions May 2013 Leading Ranks and Lagging Percentages: Analytic Functions, Continued July 2013 Pivotal Access to Your Data: Analytic Functions, Concluded The articles cover topics such as GROUP BY, SUM, AVG, HAVING, window functions, RANK, FIRST, LAST, LAG, LEAD etc.   The great news is that  you can try out the examples in this series. All you need is access to an Oracle Database instance.
