• VB like with keywords in C#

  - by Tanzim Saqib

  AspectF is an open source utility which offers separation of concerns in fluent way. I am personally a big fan as well as contributor of this project. It is very simple, easy to implement, and an excellent way to incorporate regular everyday logics into your business code from one single class, AspectF. I have added couple of new features to it, which are yet to be committed to the source control. However, here’s one feature that I have introduced today is to be able to write VB-like with keyword...(read more)

• What do you do when you encounter an idiotic interview question?

  - by Senthil

  I was interviewing with a "too proud of my java skills"-looking person. He asked me "What is your knowledge on Java IO classes.. say.. hash maps?" He asked me to write a piece of java code on paper - instantiate a class and call one of the instance's methods. When I was done, he said my program wouldn't run. After 5 minutes of serious thinking, I gave up and asked why. He said I didn't write a main function so it wouldn't run. ON PAPER. [I am too furious to continue with the stupidity...] Believe me it wasn't trick questions or a psychic or anger management evaluation thing. I can tell from his face, he was proud of these questions. That "developer" was supposed to "judge" the candidates. I can think of several things: Hit him with a chair (which I so desperately wanted to) and walk out. Simply walk out. Ridicule him saying he didn't make sense. Politely let him know that he didn't make sense and go on to try and answer the questions. Don't tell him anything, but simply go on to try and answer the questions. So far, I have tried just 4 and 5. It hasn't helped. Unfortunately many candidates seem to do the same and remain polite but this lets these kind of "developers" just keep ascending up the corporate ladder, gradually getting the capacity to pi** off more and more people. How do you handle these interviewers without bursting your veins? What is the proper way to handle this, yet maintain your reputation if other potential employers were to ever get to know what happened here? Is there anything you can do or should you even try to fix this? P.S. Let me admit that my anger has been amplified many times by the facts: He was smiling like you wouldn't believe. I got so many (20 or so) calls from that company the day before, asking me to come to the interview, that I couldn't do any work that day. I wasted a paid day off.

• How To Build An Enterprise Application - Introduction

  - by Tuan Nguyen

  An enterprise application is a software which fulfills 4 core quality attributes: Reliability Flexibility Reusability Maintainability Reliability is the ability of a system or component to perform its required functions under stated conditions for a specific period of time. Because there are no ways more than testing to make sure a system is reliability, we can exchange the term reliability with the term testability. Flexibility is the ability of changing a system's core features without violating unrelated features or components. Although flexibility can helps us to achieve interoperability easily but the opposite is not true. For example, a program might run on multiple platforms, contains logic for many scenarios but that wouldn't mean it was flexibility if it forces us rewrite code in all components when we just want to change some aspects of a feature it had. Reusability is the ability of sharing one or more system's components for another system. We should just open a component's reusability in the context in which it is used. For example, we write classes that implement UI logic and deliver them to only classes which implementing UI. Maintainability is the ability of adding or removing features to a system after it was released. Maintainability consists of many factors such as readability, analyzability, extensibility therein extensibility is critical. Maintainability requires us to write code that is longer and complexer than normal but it doesn't mean we introduce unneccessarily complex code. We always try to make our code clear and transparent to everyone. An application enterprise is built on an enterprise design which consists of two parts: low-level design and high-level design. At low-level design, it focuses on building loose-coupled classes or components. Particularly, it recommends: Each class or component undertakes only single responsibility (design based on unit test) Classes or components implement and work through interfaces (design based on contract) Dependency relationship between classes and components could be injected at run-time (design based on dependency) At high-level design, it focuses on architecting system into tiers and layers. Particularly, it recommends: Divide system into subsystems for deployment. Each subsytem is called a tier. Typical, an enterprise application would have 3 tiers as illustrated in the following figure: Arrange classes and components to logical containers called layers. Typical, an enterprise application would have 5 layers as illustrated in the following figure

• Retrieving system information without WMI

  - by user94481

  I want to write an application where I can fetch system information like CPU-Z (for example) does. I don't want to rely on WMI, because I want to grab stuff like information about the manufacturing process of the GPU (like from a database) and I don't want to maintain this by myself, because that would require too much effort. I already came up with HWiNFO32 SDK but I wonder if there are any (maybe free) alternatives to it?

• SQLAuthority News – SQL Server Wait Stats – eBook to Download on Kindle – Answer to FREE PDF Download Request

  - by pinaldave

  Being a book author is a completely new experience for me. I am yet to come across the issues faced by expert book authors. I assume that these interesting issues can be routine ones for expert book authors. One of the biggest requests I am getting for my SQL Server Wait Stats [Amazon] | [Flipkart] | [Kindle] book is my humble attempt to write a book. This is our very first experiment, and the book is beginning of the subject of SQL Server Wait Stats; we will come up with a new version of the book later next year when we have enough information for the SQL Server 2012 version. Following are the top 2 requests that I keep on receiving in emails, on blogs, Twitter, and Facebook. “Please send us FREE PDF of your book so we do not have to purchase it.” “If you can share with us the eBook (free and downloadable) format of your book, we will share it with everybody we know and you will get additional exposure.” Here is my response for the abovementioned requests: If you really need my book and cannot purchase it due to financial trouble, then feel free to let me know and I will purchase it myself and ship it to you. If you are in a country where the print book not available, then you can buy the Kindle book, which is available online in any country, and you can just read it on your computer and mobile devices. You DO NOT have to own a Kindle to read a Kindle format book. You can freely download Kindle software on your desired format and purchase the book online. For next 5 days, the kindle book is available at 3.99 in USA, and in other countries, the price is anywhere between 3.99 and 5.99. The price will go up by USD 2 everywhere across the world after 1st November, 2011. Here is the link to download Kindle Software for free PC, WP7, and in marketplace for various other mobile devices. I thank you for giving warm response to SQL Server Wait Stats book. I am motivated to write the next expanded version of this book.

• Teacher demands excessive/unjustified use of Design Patterns

  - by SoboLAN

  I study computer science and I have a class called "Programming Techniques". Its purpose is to teach (us) good object oriented design principles. During the semester we have homeworks, programs that we must write to demonstrate what we've learned. The lab assistant demands for each of these homeworks that specific design patterns should be used. For example, the current homework is an application used for processing customer orders. We are demanded to use either "Factory Method" or "Abstract Factory" design patterns for this. It gets even worse: at the end of the semester we must write a program (something more complex) that must use at least one creational pattern, at least one structural pattern and at least one behavioural pattern. Is it normal to demand this ? I mean, forcing us to design our programs in such a way that a specific design pattern makes sense is just beyond what I consider ok. If I'm a car mechanic and have a huge tool box, then I will use a certain tool from that box if and when the situation demands it. Not more, not less. If my design of the application doesn't demand at all the use of "Abstract Factory" (for example), then why should I implement it ? I'm not sure yet if the senior lecturer agrees with what the lab assistant is demanding, but I want to talk to him about it and I need solid arguments to do so. How should I approach this problem with him ? PS: I'm sure there must be a better way to teach us these things. Maybe making us each week read about 3 design patterns and the next week giving us a test with small but specific programming or architectural situations/problems. The goal in that test would be to identify what design patterns would make sense and how they could be implemented. This way, he can see if we understand them. EDIT: These homeworks are not just 100-line programs, they have quite a lot of requirements and are fairly complicated. This is the reason we have about 2 - 3 weeks of deadline for each of them. I agree that practicing this is the best way to learn. But shouldn't smaller programs/applications be used for this ? Something just for demonstrating purposes. Not big programs with lots of requirements/classes/etc.

• Looking for a C# implementation of (Pk) Zip32

  - by bukko

  I need to implement Zip32 (PK compatible) in C#. I can't just call a separate dll or exe because (1) I don't want to write the uncompressed file to disk and (2) I want to avoid the possibly that someone could wrap that library - either of these would compromise security. My ideal solution would be to find a C# implementation of the Zip32 algorithm which I could use, and just modify it so I can pass a byte array or something. Does anyone have any suggestions or (I dare but hope) examples of C# PKZip implementations?

• Ruby: how to step through ruby code

  - by user1647484

  I'm trying to learn how to step through Ruby code (written by more experienced programmers) in order to improve my knowledge of Ruby. Problem is that I don't really know how to do it well. Googling the topic brought me to an about.com page on Ruby; I thought a higher quality more comprehensive answer should belong on StackOverflow, so if anyone can write an answer (with an example) for it, showing how a beginner can step through code to learn as much as possible about it, it'd be much appreciated.

• XNA: Networking gone totally out of sync

  - by MesserChups

  I'm creating a multiplayer interface for a game in 2D some of my friends made, and I'm stuck with a huge latency or sync problem. I started by adapting my game to the msdn xna network tutorial and right now when I join a SystemLink network session (1 host on PC and 1 client on Xbox) I can move two players, everything is ok, but few minutes later the two machines start being totally out of synchronization. When I move one player it takes 10 or 20 seconds (increasing with TIME) to take effect on the second machine. I've tried to : Create a thread which calls NetworkSession.Update() continuously as suggested on this forum, didn't worked. Call the Send() method one frame on 10, and the receive() method at each frame, didn't worked either. I've cleaned my code, flushed all buffers at each call and switched the host and client but the problem still remain... I hope you have a solution because I'm running out of ideas... Thanks SendPackets() code : protected override void SendPackets() { if ((NetworkSessionState)m_networkSession.SessionState == NetworkSessionState.Playing) //Only while playing { //Write in the packet manager m_packetWriter.Write(m_packetManager.PacketToSend.ToArray(), 0, (int)m_packetManager.PacketToSend.Position); m_packetManager.ResetPacket(); //flush //Sends the packets to all remote gamers foreach (NetworkGamer l_netGamer in m_networkSession.RemoteGamers) { if (m_packetWriter.Length != 0) { FirstLocalNetGamer.SendData(m_packetWriter, SendDataOptions.None, l_netGamer); } } m_packetWriter.Flush();//m m_packetWriter.Seek(0, 0); } } ReceivePackets() code : public override void ReceivePackets() { base.ReceivePackets(); if ((NetworkSessionState)m_networkSession.SessionState == NetworkSessionState.Playing) //Only while playing { if (m_networkSession.LocalGamers.Count > 0) //Verify that there's at least one local gamer { foreach (LocalNetworkGamer l_localGamer in m_networkSession.LocalGamers) { //every LocalNetworkGamer must read to flush their stream // Keep reading while packets are available. NetworkGamer l_oldSender = null; while (l_localGamer.IsDataAvailable) { // Read a single packet, even if we are the host, we must read to clear the queue NetworkGamer l_newSender; l_localGamer.ReceiveData(m_packetReader, out l_newSender); if (l_newSender != l_oldSender) { if ((!l_newSender.IsLocal) && (l_localGamer == FirstLocalNetGamer)) { //Parsing PacketReader to MemoryStream m_packetManager.Receive(new MemoryStream(m_packetReader.ReadBytes(m_packetReader.Length))); } } l_oldSender = l_newSender; m_packetReader.BaseStream.Flush(); m_packetReader.BaseStream.Seek(0, SeekOrigin.Begin); } } m_packetManager.ParsePackets(); } } }

• Testing Workflows &ndash; Test-After

  - by Timothy Klenke

  Originally posted on: http://geekswithblogs.net/TimothyK/archive/2014/05/30/testing-workflows-ndash-test-after.aspxIn this post I’m going to outline a few common methods that can be used to increase the coverage of of your test suite.  This won’t be yet another post on why you should be doing testing; there are plenty of those types of posts already out there.  Assuming you know you should be testing, then comes the problem of how do I actual fit that into my day job.  When the opportunity to automate testing comes do you take it, or do you even recognize it? There are a lot of ways (workflows) to go about creating automated tests, just like there are many workflows to writing a program.  When writing a program you can do it from a top-down approach where you write the main skeleton of the algorithm and call out to dummy stub functions, or a bottom-up approach where the low level functionality is fully implement before it is quickly wired together at the end.  Both approaches are perfectly valid under certain contexts. Each approach you are skilled at applying is another tool in your tool belt.  The more vectors of attack you have on a problem – the better.  So here is a short, incomplete list of some of the workflows that can be applied to increasing the amount of automation in your testing and level of quality in general.  Think of each workflow as an opportunity that is available for you to take. Test workflows basically fall into 2 categories:  test first or test after.  Test first is the best approach.  However, this post isn’t about the one and only best approach.  I want to focus more on the lesser known, less ideal approaches that still provide an opportunity for adding tests.  In this post I’ll enumerate some test-after workflows.  In my next post I’ll cover test-first. Bug Reporting When someone calls you up or forwards you a email with a vague description of a bug its usually standard procedure to create or verify a reproduction plan for the bug via manual testing and log that in a bug tracking system.  This can be problematic.  Often reproduction plans when written down might skip a step that seemed obvious to the tester at the time or they might be missing some crucial environment setting. Instead of data entry into a bug tracking system, try opening up the test project and adding a failing unit test to prove the bug.  The test project guarantees that all aspects of the environment are setup properly and no steps are missing.  The language in the test project is much more precise than the English that goes into a bug tracking system. This workflow can easily be extended for Enhancement Requests as well as Bug Reporting. Exploratory Testing Exploratory testing comes in when you aren’t sure how the system will behave in a new scenario.  The scenario wasn’t planned for in the initial system requirements and there isn’t an existing test for it.  By definition the system behaviour is “undefined”. So write a new unit test to define that behaviour.  Add assertions to the tests to confirm your assumptions.  The new test becomes part of the living system specification that is kept up to date with the test suite. Examples This workflow is especially good when developing APIs.  When you are finally done your production API then comes the job of writing documentation on how to consume the API.  Good documentation will also include code examples.  Don’t let these code examples merely exist in some accompanying manual; implement them in a test suite. Example tests and documentation do not have to be created after the production API is complete.  It is best to write the example code (tests) as you go just before the production code. Smoke Tests Every system has a typical use case.  This represents the basic, core functionality of the system.  If this fails after an upgrade the end users will be hosed and they will be scratching their heads as to how it could be possible that an update got released with this core functionality broken. The tests for this core functionality are referred to as “smoke tests”.  It is a good idea to have them automated and run with each build in order to avoid extreme embarrassment and angry customers. Coverage Analysis Code coverage analysis is a tool that reports how much of the production code base is exercised by the test suite.  In Visual Studio this can be found under the Test main menu item. The tool will report a total number for the code coverage, which can be anywhere between 0 and 100%.  Coverage Analysis shouldn’t be used strictly for numbers reporting.  Companies shouldn’t set minimum coverage targets that mandate that all projects must have at least 80% or 100% test coverage.  These arbitrary requirements just invite gaming of the coverage analysis, which makes the numbers useless. The analysis tool will break down the coverage by the various classes and methods in projects.  Instead of focusing on the total number, drill down into this view and see which classes have high or low coverage.  It you are surprised by a low number on a class this is an opportunity to add tests. When drilling through the classes there will be generally two types of reaction to a surprising low test coverage number.  The first reaction type is a recognition that there is low hanging fruit to be picked.  There may be some classes or methods that aren’t being tested, which could easy be.  The other reaction type is “OMG”.  This were you find a critical piece of code that isn’t under test.  In both cases, go and add the missing tests. Test Refactoring The general theme of this post up to this point has been how to add more and more tests to a test suite.  I’ll step back from that a bit and remind that every line of code is a liability.  Each line of code has to be read and maintained, which costs money.  This is true regardless whether the code is production code or test code. Remember that the primary goal of the test suite is that it be easy to read so that people can easily determine the specifications of the system.  Make sure that adding more and more tests doesn’t interfere with this primary goal. Perform code reviews on the test suite as often as on production code.  Hold the test code up to the same high readability standards as the production code.  If the tests are hard to read then change them.  Look to remove duplication.  Duplicate setup code between two or more test methods that can be moved to a shared function.  Entire test methods can be removed if it is found that the scenario it tests is covered by other tests.  Its OK to delete a test that isn’t pulling its own weight anymore. Remember to only start refactoring when all the test are green.  Don’t refactor the tests and the production code at the same time.  An automated test suite can be thought of as a double entry book keeping system.  The unchanging, passing production code serves as the tests for the test suite while refactoring the tests. As with all refactoring, it is best to fit this into your regular work rather than asking for time later to get it done.  Fit this into the standard red-green-refactor cycle.  The refactor step no only applies to production code but also the tests, but not at the same time.  Perhaps the cycle should be called red-green-refactor production-refactor tests (not quite as catchy).   That about covers most of the test-after workflows I can think of.  In my next post I’ll get into test-first workflows.

• I'm creating my own scalable, rapid prototyping web server. How should I design it?

  - by Mike Willliams

  I'm going to create my own web server that focuses on scalability, rapid prototyping and the use of JavaScript as the server's scripting language, much like node.js. It will use a Model-View-Controller design pattern so a web application can support more concurrent users just by adding hardware -- and not having to redesign the software. Basically, I'm aiming to produce a framework that allows for fast and easy development of cloud applications without the need to write lots of boiler plate code. I've got some questions about this... How hard will it be to put MySQL in the cloud? How could I go about implementing this and make the resulting product free? Will I have to write my own engine or modify an existing one, if I do what should I watch out for? To make this scalable I need to adjust from one server to hundreds of servers this creates the requirement for the servers to be load balancing, how should I do this? If I balance based on the work load per server I would need gateway to handle all the incoming requests. Is it the right idea to have all the servers check into the gateway and update there status. By having the servers run through a gateway if the gateway dies all the incoming requests are ignored. I'm thinking that having all the servers maintain a list of each other, or at least a few I could rebuild the list of servers and establish a new gateway. Is it worth it? Or should I have a backup gateway that could switch out? Should I let the user choose? How should I pick which server handles the database and which handles the page serving? Should I spread the database so that queries are preformed on multiple servers? Which would theoretically improve performance. The servers would need to mirror the database at least once so that if a server goes down the database isn't corrupted. So this brings up writing another question, should I broadcast SQL queries so that all the servers can take a bit of the work load? If I do it that way wouldn't a query clog up the network so that other queries couldn't be preformed? What are my alternatives? Finally, is there a free solution already out there that might need a little modification that suits my needs?

• Undocumented Query Plans: Equality Comparisons

  The diagram below shows two data sets, with differences highlighted: To find changed rows using TSQL, we might write a query like this: The logic is clear: join rows from the two sets together on the primary key column, and return rows where a change has occurred in one or more data columns.  Unfortunately, this query only finds one of the expected four rows: The problem, of course, is that our query does not correctly handle NULLs.  The ‘not equal to’ operators <> and != do not evaluate...(read more)

• The Diabolical Developer: What You Need to Do to Become Awesome

  - by Tori Wieldt

  Wearing sunglasses and quite possibly hungover, Martijn Verburg's evil persona provided key tips on how to be a Diabolical Developer. His presentation at TheServerSide Java Symposium was heavy on the sarcasm and provided lots of laughter. Martijn insisted that developers take their power back and get rid of all the "modern fluff" that distract developers.He provided several key tips to become a Diabolical Developer:*Learn only from yourself. Don't read blogs or books, and don't attend conferences. If you must go on forums, only do it display your superiority, answer as obscurely as possible.*Work aloneBest coding happens when you alone in your room, lock yourself in for days. Make sure you have a gaming machine in with you.*Keep information to yourselfKnowledge is power. Think job security. Never provide documentation. *Make sure only you can read your code.Don't put comments in your code. Name your variables A,B,C....A1,B1, etc.If someone insists you format your in a standard way, change a small section and revert it back as soon as they walk away from your screen. *Stick to what you knowStay on Java 1.3. Don't bother learning abstractions. Write your application in a single file. Stuff as much code into one class as possible, a 30,000-line class is fine. Makes it easier for you to read and maintain.*Use Real ToolsNo "fancy-pancy" IDEs. Real developers only use vi.*Ignore FadsThe cloud is massively overhyped. Mobile is a big fad for young kids.The big, clunky desktop computer (with a real keyboard) will return.Learn new stuff only to pad your resume. Ajax is great for that. *Skip TestingTest-driven development is a complete waste of time. They sent men to the moon without unit tests.Just write your code properly in the first place and you don't need tests.*Compiled = Ship ItUser acceptance testing is an absolute waste of time. *Use a Single ThreadDon't use multithreading. All you need to do is throw more hardware at the problem.*Don't waste time on SEO.If you've written the contract correctly, you are paid for writing code, not attracting users.You don't want a lot of users, they only report problems. *Avoid meetingsFake being sick to avoid meetings. If you are forced into a meeting, play corporate bingo.Once you stand up and shout "bingo" you will kicked out of the meeting. Job done.Follow these tips and you'll be well on your way to being a Diabolical Developer!

• SSAS Tabular Workshop online and other upcoming dates (and updates!) #ssas #tabular

  - by Marco Russo (SQLBI)

  After many conferences and travels, this summer I had some time to write and prepare new sessions for the next wave of conferences. In reality I am just doing that, even if I already restarted traveling for consulting and training. So expect new content about DAX and Tabular coming in the next months! Starting to see real customer adopting Tabular is showing many new challenges and there is still a lot to learn and to create. If you still didn’t started working on Tabular, well, you should. As I always say, as a BI developer you should be able to choose between Tabular and Multidimensional, and in order to do that you should know both of them! One thing that I don’t like very much about marketing is that “Tabular is simpler”, because it’s often translated in “Tabular is for simple projects” when this last statement is not true. Actually, I see a lot of good reasons to adopt Tabular in complex data models, especially in non-traditional scenarios. I know, this is because I love to understand what are the actual limits of a technology, and I’m learning that there is simple a lot of space of improvement also for Tabular. It’s already fast, but it could be faster! How can you start? Well, first of all, by reading our book. Then, by attending to our SSAS Tabular workshop. There is an online edition of the workshop on September 3-4, 2012 (hurry up if you want to register), and there are already several dates planned for the next months (and others will be added soon!). And, of course, by installing SQL Server 2012 and trying to create models over your databases. If you are too lazy, just start with PowerPivot. As soon as you start working with Tabular or PowerPivot, you will see that there is one important skill you need: learning DAX. In the next few days I should publish an article that I’m finishing these days about best practices using SUMMARIZE and ADDCOLUMNS. If only someone published this article one year ago, I would have saved many hours of my life. But, you know, flight manuals are written in blood… and someone has to write! Stay tuned.

• Can't start Psychonauts game -- segfault

  This looks similar to Psychonauts Humble Indie Bundle V error but I don't have the ERROR message (missing GL capability) and its solution does not work for me. When trying to run Psychonauts from the Humble Indie Bundle on my x86_64 laptop running Ubuntu 12.04 I get the following output: <bjn@segnus:/usr/local/games/psychonauts>$ ./Psychonauts STUBBED: fix up the rest of the SSE code first at DetectSSESupport (/home/icculus/projects/psychonauts/Source/CommonLibs/DFMath/MathGeneral.cpp:32) STUBBED: write me? at SetPCLanguage (/home/icculus/projects/psychonauts/Source/game/luatest/UnixMain.cpp:120) STUBBED: fix up the rest of the SSE code first at DetectCPUCaps (/home/icculus/projects/psychonauts/Source/game/luatest/Game/PCGameApp.cpp:223) STUBBED: check LANG envr var at _GetDefaultGameLanguage (/home/icculus/projects/psychonauts/Source/game/luatest/Game/GameApp.cpp:171) Console created Save path: /home/bjn/.local/share/Psychonauts Write path: WorkResource STUBBED: inline asm at SSEMul_4x4_4x4_2arg (/home/icculus/projects/psychonauts/Source/CommonLibs/DFMath/Matrix.cpp:710) STUBBED: inline asm at SSEMul_4x4_4x4_3arg (/home/icculus/projects/psychonauts/Source/CommonLibs/DFMath/Matrix.cpp:698) ******** unit test failed ******** STUBBED: VK_* at InitInputNames (/home/icculus/projects/psychonauts/Source/CommonLibs/DirectX/SDLInput.cpp:1220) No joysticks detected Transport started DaveD: NCListenSocket: Listening on port 40001 SDL_SetVideoMode() failed: Failed loading libGL.so.1 Start Up completed in 0.06 seconds [1] 9718 segmentation fault (core dumped) ./Psychonauts <bjn@segnus:/usr/local/games/psychonauts>$ Output of lspci: 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07) 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03) 00:1a.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03) 00:1a.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 03) 00:1a.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 03) 00:1a.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 03) 00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 2 (rev 03) 00:1c.3 PCI bridge: Intel Corporation 82801I (ICH9 Family) PCI Express Port 4 (rev 03) 00:1d.0 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev 93) 00:1f.0 ISA bridge: Intel Corporation ICH9M-E LPC Interface Controller (rev 03) 00:1f.2 RAID bus controller: Intel Corporation 82801 Mobile SATA Controller [RAID mode] (rev 03) 00:1f.3 SMBus: Intel Corporation 82801I (ICH9 Family) SMBus Controller (rev 03) 02:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05) 02:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 22) 0c:00.0 Network controller: Intel Corporation WiFi Link 5100 Any ideas?

• Programming and Ubiquitous Language (DDD) in a non-English domain

  - by Sandor Drieënhuizen

  I know there are some questions already here that are closely related to this subject but none of them take Ubiquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with mixed languages anyway. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options? UPDATE Today, about year later, having dealt with this issue on a daily basis, I have to say that option 3 has worked out pretty well for me. It wasn't as tedious as I initially feared and translating in real time while talking to the client wasn't a problem either. I also found the following advantages to be true, based on my experience. Translating the UL makes you pay more attention to defining the UL and even the domain itself, especially when you don't know how to translate a term and you have to start looking through dictionaries etc. This has even caused me to reconsider domain modeling decisions a few times. It helps you make your knowledge of the English language more profound. Obviously, your code is much more pleasant to look at instead of being a mind boggling obscenity.

• Filtering your offices IPs from Google Analytics when each has a dynamic IP?

  - by leeand00

  I found the documentation for filtering IPs from Google Analytics, but the address of the several locations of our company all have dynamic IP addresses that change every 30 days from what I'm told. I know from working with Dynamic DNS that the provider usually gives you a script that you configure your router to run when it's IP address changes or when it is restarted, which passes the new IP address to the DDNS server. I'm wondering if there might be a way to write or use a preexisting script to do the same thing with the Google Analytics API.

• What non-programming tools do programmers use?

  - by user828584

  I'm reading code complete with the intention of learning how to better structure my code, but I'm also learning a lot about how many aspects of programming something there are that aren't just writing the code. The book talks a lot about problem definition, determining the requirements, defining the structure, designing the code, etc. What tools are used for these non-writing steps of programming? Is there software that will help me design and plan out what I'm going to write before I do?

• Reading/Writing Promoted Properties from BRE

  - by Sean Feldman

  ESB Toolkit Extensions is an open-source library giving you an extended BRE/BRI provider to read and write promoted properties of a message within business rules engine. I’ve used it to achieve automated process for mapping to canonical schema and then back to destination schema based on receiver ID as a promoted property (will blog on this later). A very useful library!
