• understanding a Build c++

  - by numerical25

  I think I know what a build is. But I am not sure. My definition of a build is another word for saying compiled application. Can someone please tell me what exactly a build is. And why do people ask for 2 types of builds. Such as Debug Build, Profile Build and a Release Build. What are the differences.

• Using [self method] or @selector(method)?

  - by fuzzygoat

  Can anyone enlighten me as to the differences between the two statements below. [self playButtonSound]; AND: [self performSelector:@selector(playButtonSound)]; I am just asking as I had some old code that used @selector, now with a little more knowledge I can't think why I did not use [self playButtonSound] instead, they both seem to do the same as written here. gary

• About Sdram software :Self-refresh mode

  - by student_pdas

  For power management we have to put system in deep sleep(system sleep) mode and for this we have to put SDRAM in self refresh mode. Can anyone tell the steps to set SDARM in self refresh mode. I tried SDRAM configuration register's ,I found that the SDRAM do goes to self-refresh mode[we probed the SD clk out] however system crashes in some scenarios while coming out of sleep.

• First PC Build (Part 1)

  - by Anthony Trudeau

  Originally posted on: http://geekswithblogs.net/tonyt/archive/2014/08/05/157959.aspxA couple of months ago I made the decision to build myself a new computer. The intended use is gaming and for using the last real version of Photoshop. I was motivated by the poor state of console gaming and a simple desire to do something I haven’t done before – build a PC from the ground up. I’ve been using PCs for more than two decades. I’ve replaced a component hear and there, but for the last 10 years or so I’ve only used laptops. Therefore, this article will be written from the perspective of someone familiar with PCs, but completely new at building. I’m not an expert and this is not a definitive guide for building a PC, but I do hope that it encourages you to try it yourself. Component List Research There was a lot of research necessary, because building a PC is completely new to me, and I haven’t kept up with what’s out there. The first thing you want to do is nail down what your goals are. Your goals are going to be driven by what you want to do with your computer and personal choice. Don’t neglect the second one, because if you’re doing this for fun you want to get what you want. In my case, I focused on three things: performance, longevity, and aesthetics. The performance aspect is important for gaming and Photoshop. This will drive what components you get. For example, heavy gaming use is going to drive your choice of graphics card. Longevity is relevant to me, because I don’t want to be changing things out anytime soon for the next hot game. The consequence of performance and longevity is cost. Finally, aesthetics was my next consideration. I could have just built a box, but it wouldn’t have been nearly as fun for me. Aesthetics might not be important to you. They are for me. I also like gadgets and that played into at least one purchase for this build. I used PC Part Picker to put together my component list. I found it invaluable during the process and I’d recommend it to everyone. One caveat is that I wouldn’t trust the compatibility aspects. It does a pretty good job of not steering you wrong, but do your own research. The rest of it isn’t really sexy. I started out with what appealed to me and then I made changes and additions as I dived deep into researching each component and interaction I could find. The resources I used are innumerable. I used reviews, product descriptions, forum posts (praises and problems), et al. to assist me. I also asked friends into gaming what they thought about my component list. And when I got near the end I posted my list to the Reddit /r/buildapc forum. I cannot stress the value of extra sets of eyeballs and first hand experiences. Some of the resources I used: PC Part Picker Tom’s Hardware bit-tech Reddit Purchase PC Part Picker favors certain vendors. You should look at others too. In my case I found their favorites to be the best. My priorities were out-the-door price and shipping time. I knew that once I started getting parts I’d want to start building. Luckily, I timed it well and everything arrived within the span of a few days. Here are my opinions on the vendors I ended up using in alphabetical order. Amazon.com is a good, reliable choice. They have excellent customer service in my experience, and I knew I wouldn’t have trouble with them. However, shipping time is often a problem when you use their free shipping unless you order expensive items (I’ve found items over $100 ship quickly). Ultimately though, price wasn’t always the best and their collection of sales tax in my state turned me off them. I did purchase my case from them. I ordered the mouse as well, but I cancelled after it was stuck four days in a “shipping soon” state. I purchased the mouse locally. Best Buy is not my favorite place to do business. There’s a lot of history with poor, uninterested sales representatives and they used to have a lot of bad anti-consumer policies. That’s a lot better now, but the bad taste is still in my mouth. I ended up purchasing the accessories from them including mouse (locally) and headphones. NCIX is a company that I’ve never heard of before. It popped up as a recommendation for my CPU cooler on PC Part Picker. I didn’t do a lot of research on the company, because their policy on you buying insurance for your orders turned me off. That policy makes it clear to me that the company finds me responsible for the shipment once it leaves their dock. That’s not right, and may run afoul of state laws. Regardless they shipped my CPU cooler quickly and I didn’t have a problem. NewEgg.com is a well known company. I had never done business with them, but I’m glad I did. They shipped quickly and provided good visibility over everything. The prices were also the best in most cases. My main complaint is that they have a lot of exchange only return policies on components. To their credit those policies are listed in the cart underneath each item. The visibility tells me that they’re not playing any shenanigans and made me comfortable dealing with that risk. The vast majority of what I ordered came from them. Coming Next In the next part I’ll tackle my build experience.

• Unable to build my c++ code with g++ 4.6.3

  - by Mriganka

  I am facing multiple issues with building my c++ code on Ubuntu 12.04. This code was building and running fine on RH Enterprise. I am using g++ 4.6.3. Here's the output of g++ -v. g++ -v Using built-in specs. COLLECT_GCC=g++ COLLECT_LTO_WRAPPER=/usr/lib/gcc/i686-linux-gnu/4.6/lto-wrapper Target: i686-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Ubuntu/Linaro 4.6.3-1ubuntu5' --with-bugurl=file:///usr/share/doc/gcc-4.6/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-4.6 --enable-shared --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.6 --libdir=/usr/lib --enable-nls --with-sysroot=/ --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-gnu-unique-object --enable-plugin --enable-objc-gc --enable-targets=all --disable-werror --with-arch-32=i686 --with-tune=generic --enable-checking=release --build=i686-linux-gnu --host=i686-linux-gnu --target=i686-linux-gnu Thread model: posix gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) Here's a sample of my code: #include "Word.h" #include < string> using namespace std; pthread_mutex_t Word::_lock = PTHREAD_MUTEX_INITIALIZER; Word::Word(): _occurrences(1) { memset(_buf, 0, 25); } Word::Word(char *str): _occurrences(1) { memset(_buf, 0, 25); if (str != NULL) { strncpy(_buf, str, strlen(str)); } } g++ -c -ansi or g++ -c -std=c++98 or g++ -c -std=c++03, none of these options are able to build the code correctly. I get the following compilation errors: mriganka@ubuntu:~/WordCount$ make g++ -c -g -ansi Word.cpp -o Word.o Word.cpp: In constructor ‘Word::Word()’: Word.cpp:10:21: error: ‘memset’ was not declared in this scope Word.cpp: In constructor ‘Word::Word(char*)’: Word.cpp:16:21: error: ‘memset’ was not declared in this scope Word.cpp:19:34: error: ‘strlen’ was not declared in this scope Word.cpp:19:35: error: ‘strncpy’ was not declared in this scope Word.cpp: In member function ‘void Word::operator=(const Word&)’: Word.cpp:37:42: error: ‘strlen’ was not declared in this scope Word.cpp:37:43: error: ‘strncpy’ was not declared in this scope Word.cpp: In copy constructor ‘Word::Word(const Word&)’: Word.cpp:44:21: error: ‘memset’ was not declared in this scope Word.cpp:45:52: error: ‘strlen’ was not declared in this scope Word.cpp:45:53: error: ‘strncpy’ was not declared in this scope So basically g++ 4.6.3 on Ubuntu 12.04 is not able to recognize the standard c++ headers. And I am not finding a way out of this situation. Second problem: In order to make progress, I included < string.h instead of < string. But now I am facing linking errors with my message queue and pthread library functions. Here's the error that I am getting: mriganka@ubuntu:~/WordCount$ make g++ -c -g -ansi Word.cpp -o Word.o g++ -lrt -I/usr/lib/i386-linux-gnu Word.o HashMap.o main.o -o word_count main.o: In function `main': /home/mriganka/WordCount/main.cpp:75: undefined reference to `pthread_create' /home/mriganka/WordCount/main.cpp:90: undefined reference to `mq_open' /home/mriganka/WordCount/main.cpp:93: undefined reference to `mq_getattr' /home/mriganka/WordCount/main.cpp:113: undefined reference to `mq_send' /home/mriganka/WordCount/main.cpp:123: undefined reference to `pthread_join' /home/mriganka/WordCount/main.cpp:129: undefined reference to `mq_close' /home/mriganka/WordCount/main.cpp:130: undefined reference to `mq_unlink' main.o: In function `count_words(void*)': /home/mriganka/WordCount/main.cpp:151: undefined reference to `mq_open' /home/mriganka/WordCount/main.cpp:154: undefined reference to `mq_getattr' /home/mriganka/WordCount/main.cpp:162: undefined reference to `mq_timedreceive' collect2: ld returned 1 exit status Here's my makefile: CC=g++ CFLAGS=-c -g -ansi LDFLAGS=-lrt INC=-I/usr/lib/i386-linux-gnu SOURCES=Word.cpp HashMap.cpp main.cpp OBJECTS=$(SOURCES:.cpp=.o) EXECUTABLE=word_count all: $(SOURCES) $(EXECUTABLE) $(EXECUTABLE): $(OBJECTS) $(CC) $(LDFLAGS) $(INC) -pthread $(OBJECTS) -o $@ .cpp.o: $(CC) $(CFLAGS) $< -o $@ clean: rm -f *.o word_count Please help me to resolve both the issues.

• Microsoft Build 2012 Day 1 Keynote Summary

  - by Tim Murphy

  So I have finally dried the tears after watching the Keynote for Build 2012.  This wasn’t because it was an emotional presentation, but because for the second year I missed the goodies.  Each on site attendee got a Surface RT, a Lumia 920 and a voucher for 100GB of SkyDrive storage. The event was opened with the announcement that in the three days since the launch of Windows 8 over 4 million upgrades have been sold.  I don’t care who you are that is an impressive stat.  Ballmer then spent a fair amount of time remaking the case for the Windows and Windows Phone platforms similar to what we have heard over the last to launch events. There were some cool, but non-essential demos.  The one that was the most fun was the Perceptive Pixel 82” slate device.  At first glance I wondered why I would ever want such a device, but then Ballmer explained it’s possible use for schools and boardrooms.  The actually made sense. Then things got strange.  Steve started explaining features that developers could leverage.  Usually this type of information is left to the product leads.  He focused on the integration with the Charms features such as Search and Share. Steve “Guggs” Guggenheim showed off an app that would appeal to my kids from Disney called “Agent P” which is base on Phineas and Ferb.  Then he got to the meat of the presentation.  We found out that you could add a tile that can be used to sell ad space.  In the same vein we also found out that you could use Microsoft’s, Paypal’s or any commerce engine of your own creation or choosing. For those who are interested in sports and especially developing sports apps you would have found the small presentation from Michael Bayle of ESPN.  He introduced the ESPN app which has tons of features.  For the developers in the crowd he also mentioned that ESPN has an API available at developer.espn.com. During the launch events we were told apps were coming.  In this presentation we were actually shown a scrolling list of logos and told about a couple of them.  Ballmer mentioned specifically Twitter, SAP and DropBox.  These are impressive names that were just a couple of the list impressive names. Steve Ballmer addressed the question of why you should develop for the Windows 8 platform.  He feels that Microsoft has the best commercial terms for developers, a better way to build apps than other platforms and a variety of form factors.  His key point though was the available volume of customers given the current Windows install base and assuming even a flat growth of the platform.  This he backed with a promise that Microsoft is going to do better at marketing and you won’t be able to avoid the ads that they are bringing out. The last section of the key note was present by Kevin Gallo from the Windows Phone team.  This was the real reason I tuned into the webcast.  He impressed upon those watching that the strength of developing for the Microsoft platform is the common programming model that now exist.  While there are difference between form factor implementations you can leverage code across them. He claimed that 90% of developer requests for Windows Phone 8 had been implemented.  These include: More controls with better performance Better live tiles including lock screen integration Speech support in custom apps Easier submission to the market place App camera integration VOIP and chat support Bluetooth and NFC support Native C++ development Direct 3D development   The quote from Kevin that stood out for me was that “Take your Dramamine and buckle your seatbelt type of games are coming to Windows Phone 8”.  He back this up by displaying a list of game development frameworks and then having Unity come out and do a demo. Ok, almost done … The last two things of note for me were the announcement that the SDK is immediately available at dev.windowsphone.com and that they were reducing the cost of an individual developer account to $8 for the next 8 days. Let the development commence. del.icio.us Tags: Build 2012,Windows 8,Windows Phone 8,Windows Phone

• Insufficient Permissions Problems with MSDeploy and TFS Build 2010

  - by jdanforth

  I ran into these problems on a TFS 2010 RC setup where I wanted to deploy a web site as part of the nightly build: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets (3481): Web deployment task failed.(An error occurred when reading the IIS Configuration File 'MACHINE/REDIRECTION'. The identity performing the operation was 'NT AUTHORITY\NETWORK SERVICE'.)  An error occurred when reading the IIS Configuration File 'MACHINE/REDIRECTION'. The identity performing the operation was 'NT AUTHORITY\NETWORK SERVICE'. Filename: \\?\C:\Windows\system32\inetsrv\config\redirection.config Error: Cannot read configuration file due to insufficient permissions  As you can see I’m running the build service as NETWORK SERVICE which is quite usual. The first thing I did then was to give NETWORK SERVICE read access to the whole directory where redirection.config is sitting; C:\Windows\system32\inetsrv\config. That gave me a new error: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets (3481): Web deployment task failed. (Attempted to perform an unauthorized operation.) The reason for this problem was that NETWORK SERVICE didn’t have write permission to the place where I’ve told MSDeploy to put the web site physically on the disk. Once I’d given the NETWORK SERVICE the right permissions, MSDeploy completed as expected! NOTE! I’ve not had this problem with TFS 2010 RTM, so it might be just a RC issue!

• Software development books are useful, but when to find the time to read them?

  - by user5396

  I have 5 books in my "read-wish-list". When do I read them? I mean I could force myself to use 1 hour during working hours, but this will last for 2 days then someone will ask me to do more "high priority things". One option can be reading at night, but also this has limits, even because I prefer to spend time with kids. Could you please share your experiences? A long term plan is needed of course, it makes no sense to read 5 books in a week, but to continuously read something. For this reason it must not be a stressful thing. It should be easy. It must not be a struggle to find time to read, but it should be done on a continuous regular basis. Somehow this question can be similar to THIS ONE but I want to ask about books. How many if you read books at work for self improvement, not to tackle a specific task?

• TFS 2010 Build: Dealing with the API restriction error

  - by Jakob Ehn

  Recently I’ve come across this error a couple of times when running builds that exeucte unit tests using Test containers: API restriction: The assembly 'file:///C:\Builds\<path>\myassembly.dll' has already loaded from a different location. It cannot be loaded from a new location within the same appdomain. Every time I’ve got this error, the project has been a web application, and the path to the assembly points down to the _PublishedWebsites directory that is created beneath the Binaries folder during a team build. The error description really says it all (although slightly cryptic), when using test containers, MSTest needs to load all assemblies and see if they contain any unit tests. During this serach, it finds the ‘myassembly.dll’ in two different locations. First it is found directly beneth the Binaries folder, and then it is alos found beneath the _PublishedWebsites\Project\bin folder. The reason is that the default setting for test containers in a TFS 2010 build definition is **\*test*.dll:   This pattern means that MSTest will search recursively for all assemblies beneath the Binaries folder, and during the search it will find the MyAssembly.dll twice. The solution is simple, set the Test assembly file specification property to *test*.dll instead, this will disable the recursive search:

• BUILD 2012 day 1 Keynote recap

  - by pluginbaby

  On October 30, 2012 Steve Ballmer kicked off the first BUILD conference keynote. Steve shared some insights around Windows 8: 4 million customers upgraded to Windows 8 over the weekend since the October 26 release (so in 3 days only!). Focus on sharing code between Windows 8 and Windows Phone 8. Syncing everything through SkyDrive Xbox Music free streaming and Xbox Smart Glass. He did all the demos himself, showing off great “Windows 8 generation” devices already available (including an 82-inch Windows 8 “slate” by Perceptive Pixel). Steve Guggenheimer (Microsoft's Corporate Vice President DPE) talked about The Business Opportunity with Windows 8.   Notable announcements of day 1: The Windows Phone 8 SDK is now available at dev.windowsphone.com (includes SDK, free version of VS2012, Blend 5, and emulators). Release of the .NET Framework for Windows Phone 8: Ability to use C# 5 or Visual Basic 11 features in your code (async programming mode, ...), share code between WP8 and Windows Store apps. Windows Phone 8 individual developer registration is reduced to $8 for the next 8 days! (hurry up…) Note: strange absence of Steven Sinofsky on stage…   Watch the entire keynote online: http://channel9.msdn.com/Events/Build/2012/1-001 Read the full transcript: http://www.microsoft.com/en-us/news/Speeches/2012/10-30BuildDay1.aspx

• How to work with Firefox nightly build [minefield]

  - by anirudha

  Most of developer love Firefox for their plugin who support for making development easier and faster. many of us use Firefox nightly build aka minefield who update daily. there is a little problem in minefield that there is less plugin on addons site of mozilla for Firefox nightly [minefield]. a solution for this problem is that you need to install the plugin who you want in nightly build from the developer site instead of add-ons site of Mozilla. the reason for that is all many of popular plugin in development for support Firefox 4. How to install follow the thing as mine : go to minefield > addons or toolbar  > addons you see a list of plugin who is not suitable for minefield now go to more link of plugin who you want to get work in Firefox 4. When you click their you go to plugin page on addons site of mozilla or maybe redirect you to developer site. if they show you plugin page then go to developer site by click on link more about developer. now you find that on the developer site they give you the same version or maybe new then you found on mozilla addons site. install the plugin and restart the minefield. you see that most of plugin now work.

• Using Sandcastle to build code contracts documentation

  - by DigiMortal

  In my last posting about code contracts I showed how code contracts are documented in XML-documents. In this posting I will show you how to get code contracts documented with Sandcastle and Sandcastle Help File Builder. Before we start, let’s download Sandcastle tools we need: Sandcastle Sandcastle Help File Builder Install Sandcastle first and then Sandcastle Help File Builder. Because we are generating only HTML based documentation we upload to server we don’t need any other tools. Of course, we need Cassini or IIS, but I expect it to be already there in your machine. Open your project and turn on XML-documentation for project and contracts. Now let’s run Sandcastle Help File Builder. We have to create new project and add our Visual Studio solution to this project. Now set the HelpFileFormat parameter value to be Website and let builder build the help. You have to wait about two or three minutes until help is ready. Take a look at your documentation that Sandcastle generated – you see not much information there about code contracts and their rules. Enabling code contracts documentation Now let’s include code contracts to documentation. Follow these steps: Open Sandcastle folder and make copy of vs2005 folder. Open CodeContracts folder (c:\program files\microsoft\contracts\) and unzip the archive from sandcastle folder. Copy all unzipped files to Sandcastle folder. Create (yes, create new) and build your Sandcastle Help File Builder documentation project again. Open help. In my case I see something like this now. As you can see then contracts are documented pretty well. We can easily turn on code contracts XML-documentation generation and all our contracts are documented automatically. To get documentation work we had to use Sandcastle help file fixes that are installed with code contracts and if we had previously Sandcastle Help File Builder project we had to create it from start to get new rules accepted. Once the documentation support for contracts works we have to do nothing more to get contracts documented.

• How can unrealscript halt event handler execution after an arbitrary number of lines with no return or error?

  - by Dan Cowell

  I have created a class that extends TcpLink and is instantiated in a custom Kismet Sequence Action. It is being instantiated correctly and is making the GET HTTP request that I need it to (I have checked my access log in apache) and Apache is responding to the request with the appropriate content. The problem I have is that I'm using the event receive mode and it appears that somehow the handler for the Opened event is halted after a specific number of lines of code have executed. Here is my code for the Opened event: event Opened() { // A connection was established WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] event opened"); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Sending simple HTTP query"); //The HTTP GET request //char(13) and char(10) are carrage returns and new lines requesttext = "userId="$userId$"&apartmentId="$apartmentId; SendText("GET /"$path$"?"$requesttext$" HTTP/1.0"); SendText(chr(13)$chr(10)); SendText("Host: "$TargetHost); SendText(chr(13)$chr(10)); SendText("Connection: Close"); SendText(chr(13)$chr(10)$chr(13)$chr(10)); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Sent request: "$requesttext); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] end HTTP query"); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] LinkState: "$LinkState); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] LinkMode: "$LinkMode); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] ReceiveMode: "$ReceiveMode); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Error: "$string(GetLastError())); } As you can see, a number of the Broadcast calls have been commented out. Initially, only the lines up to the Broadcast containing "[DNomad_TcpLinkClient] Sent request: " were being executed and none of the Broadcasts were commented out. After commenting out that line, the next Broadcast was successful and so on and so forth. As a test, I commented out the very first Broadcast to see if the connection closing had any effect: // A connection was established //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] event opened"); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Sending simple HTTP query"); Upon doing that, an additional Broadcast at the end of the function executed. Thus the inference that there is an upper limit to the number of lines executed. Additionally, my ReceivedText handler is never called, despite Apache returning the correct HTTP 200 response with a body. My working hypothesis is that somehow after the Sequence Action finishes executing the garbage collector cleans up the TcpLinkClient instance. My biggest source of confusion with that is how on earth it does it during the execution of an event handler. Has anyone ever seen anything like this before? My full TcpLinkClient class is below: /* * TcpLinkClient based on an example usage of the TcpLink class by Michiel 'elmuerte' Hendriks for Epic Games, Inc. * */ class DNomad_TcpLinkClient extends TcpLink; var PlayerController PC; var string TargetHost; var int TargetPort; var string path; var string requesttext; var string userId; var string apartmentId; var string statusCode; var string responseData; event PostBeginPlay() { super.PostBeginPlay(); } function DoTcpLinkRequest(string uid, string id) //removes having to send a host { userId = uid; apartmentId = id; Resolve(targethost); } function string GetStatus() { return statusCode; } event Resolved( IpAddr Addr ) { // The hostname was resolved succefully WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] "$TargetHost$" resolved to "$ IpAddrToString(Addr)); // Make sure the correct remote port is set, resolving doesn't set // the port value of the IpAddr structure Addr.Port = TargetPort; //dont comment out this log because it rungs the function bindport WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Bound to port: "$ BindPort() ); if (!Open(Addr)) { WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Open failed"); } } event ResolveFailed() { WorldInfo.Game.Broadcast(self, "[TcpLinkClient] Unable to resolve "$TargetHost); // You could retry resolving here if you have an alternative // remote host. //send failed message to scaleform UI //JunHud(JunPlayerController(PC).myHUD).JunMovie.CallSetHTML("Failed"); } event Opened() { // A connection was established //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] event opened"); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Sending simple HTTP query"); //The HTTP GET request //char(13) and char(10) are carrage returns and new lines requesttext = "userId="$userId$"&apartmentId="$apartmentId; SendText("GET /"$path$"?"$requesttext$" HTTP/1.0"); SendText(chr(13)$chr(10)); SendText("Host: "$TargetHost); SendText(chr(13)$chr(10)); SendText("Connection: Close"); SendText(chr(13)$chr(10)$chr(13)$chr(10)); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Sent request: "$requesttext); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] end HTTP query"); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] LinkState: "$LinkState); //WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] LinkMode: "$LinkMode); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] ReceiveMode: "$ReceiveMode); WorldInfo.Game.Broadcast(self, "[DNomad_TcpLinkClient] Error: "$string(GetLastError())); } event Closed() { // In this case the remote client should have automatically closed // the connection, because we requested it in the HTTP request. WorldInfo.Game.Broadcast(self, "Connection closed."); // After the connection was closed we could establish a new // connection using the same TcpLink instance. } event ReceivedText( string Text ) { WorldInfo.Game.Broadcast(self, "Received Text: "$Text); //we dont want the header info, so we split the string after two new lines Text = Split(Text, chr(13)$chr(10)$chr(13)$chr(10), true); WorldInfo.Game.Broadcast(self, "Split Text: "$Text); statusCode = Text; } event ReceivedLine( string Line ) { WorldInfo.Game.Broadcast(self, "Received Line: "$Line); } event ReceivedBinary( int Count, byte B[255] ) { WorldInfo.Game.Broadcast(self, "Received Binary of length: "$Count); } defaultproperties { TargetHost="127.0.0.1" TargetPort=80 //default for HTTP LinkMode=MODE_Text ReceiveMode=RMODE_Event path = "dnomad/datafeed.php" userId = "0"; apartmentId = "0"; statusCode = ""; send = false; }

• How to get multiple open-source projects to use a standard way of doing something.

  - by Marco

  Problem In the last couple weeks, I've used 3 different "repository" tools (listed in alphabetical order): gradle ivy maven I'm calling them "repository" tools because I've also used sbt -- which fortunately uses ivy to manage it's cache or local repository. Each of these tools will create it's own repository. The defaults are: ~/.m2/repository for maven ~/.gradle/cache ~/.ivy2/cache Why can't they all use the same cache? Goal I'd like to change the world so that all three build tools could use the same cache. I'm looking for advice about issues I'm likely to run into and smart ways to get around them. By "use the same cache", I do not mean "retrieve from another build tool's cache". I mean "retrieve from and store in another build tool's cache". While I could go ahead and submit issues to the three projects, I know from experience (as a developer on an open source project), that if you want something done, you're best off getting it done yourself. Also, it seems like I need to get all 3 communities on board to some degree. What is the recommended approach for getting this kind of thing done? How do I approach the different communities? Do I work on patches for the 3 different projects, or would it be better off to create my own "interface" project that deals with these issues and have the 3 tools interface with that? Is this a standards question that I need to address on that front? Lastly, if I'm missing something and this is possible (in an globally configurable fashion), then please let me know.

• Best practice with pyGTK and Builder XML files

  - by Phoenix87

  I usually design GUI with Glade, thus producing a series of Builder XML files (one such file for each application window). Now my idea is to define a class, e.g. MainWindow, that inherits from gtk.Window and that implements all the signal handlers for the application main window. The problem is that when I retrieve the main window from the containing XML file, it is returned as a gtk.Window instance. The solution I have adopted so far is the following: I have defined a class "Window" in the following way class Window(): def __init__(self, win_name): builder = gtk.Builder() self.builder = builder builder.add_from_file("%s.glade" % win_name) self.window = builder.get_object(win_name) builder.connect_signals(self) def run(self): return self.window.run() def show_all(self): return self.window.show_all() def destroy(self): return self.window.destroy() def child(self, name): return self.builder.get_object(name) In the actual application code I have then defined a new class, say MainWindow, that inherits frow Window, and that looks like class Main(Window): def __init__(self): Window.__init__(self, "main") ### Signal handlers ##################################################### def on_mnu_file_quit_activated(self, widget, data = None): ... The string "main" refers to the main window, called "main", which resides into the XML Builder file "main.glade" (this is a sort of convention I decided to adopt). So the question is: how can I inherit from gtk.Window directly, by defining, say, the class Foo(gtk.Window), and recast the return value of builder.get_object(win_name) to Foo?

• Cleaning your BizTalk Build Server

  - by Michael Stephenson

  Just a little note for myself this one.At one of my customers where it is still BizTalk 2006 one of the build servers is intermittently getting issues so I wanted to run a script periodically to clean things up a little.  The below script is an example of how you can stop cruise control and all of the biztalk services, then clean the biztalk databases and reset the backup process and then click everything off again.This should keep the server a little cleaner and reduce the number of builds that occasionally fail for adhoc environmental issues.REM Server Clean ScriptREM =================== REM This script is ran to move the build server back to a clean state echo Stop Cruise Controlnet stop CCService echo Stop IISiisreset /stop echo Stop BizTalk Servicesnet stop BTSSvc$<Name of BizTalk Host><Repeat for other BizTalk services> echo Stop SSOnet stop ENTSSO echo Stop SQL Job Agentnet stop SQLSERVERAGENT echo Clean Message Boxsqlcmd -E -d BizTalkMsgBoxDB -Q "Exec bts_CleanupMsgbox"sqlcmd -E -d BizTalkMsgBoxDB -Q "Exec bts_PurgeSubscriptions"  echo Clean Tracking Databasesqlcmd -E -d BizTalkDTADb -Q "Exec dtasp_CleanHMData" echo Reset TDDS Stream Statussqlcmd -E -d BizTalkDTADb -Q "Update TDDS_StreamStatus Set lastSeqNum = 0" echo Force Full Backupsqlcmd -E -d BizTalkMgmtDB -Q "Exec sp_ForceFullBackup" echo Clean Backup Directorydel E:\BtsBackups\*.* /q  echo Start SSOnet start ENTSSO echo Start SQL Job Agentnet start SQLSERVERAGENT echo Start BizTalk Servicesnet start BTSSvc$<Name of BizTalk Host><Repeat for other BizTalk services> echo Start IISiisreset /start echo Start Cruise Controlnet start CCService

This is a great video of Steve Sanderson talking about SPAs, npm, Knockout, Grunt, Gulp, ect. I highly recommend it.
