• How do you communicate improvements in tools and process to the development team?

  - by birryree

  Hi everyone, My team does a lot of internal tooling and infrastructure work - you can think of us as a small scale version of the teams Facebook, Etsy, Netflix, etc. who build all the infrastructure for scaling their services up to thousands/tens of thousands of servers and supporting millions of users. Lately, we've been running full steam ahead improving much of the tools we use internally, like tools for automatically creating new servers, setting up new application instances, etc. An end result of this has been decreased developer frustration, but increased 'ignorance' by most of the developer team about how to use our tools correctly and effectively. More often than not, my team will be asked by other teams to help them use the tools. Solutions we've thought up or things already in place: All our code is relatively simple and self-explanatory, with good comments where necessary, so developers could read the scripts. Counterargument: You can guess this isn't a particularly good idea, having people read our tools' code to figure out how to use it. All our code is committed to Subversion with very detailed commit messages about changes, developers could read the commit emails. Counterargument: Expect the developers to read all our commits? Ludicrous. Wiki - we have an internal company wiki, that we try to maintain with up to date information, but as we are moving so fast, the wiki has to keep pace as well. Counterargument: As mentioned, we move fast in my team, as more improvements on our tools are added daily. Again still relies on people to read something that might change constantly. Email the team? We could email the team when we have a glut of improvements to communicate. So as you can all see, we are trying to find new ideas, and explore options we haven't thought of yet. Anyone else ever been in a similar situation and have some guidance?

• How do I apply 2 rotations about different points to a single primitive using OpenGL

  - by Fenoec

  I'm working on a 2D top-down shooter game that has a rotation feature like Realm Of The Mad God such that if you press e the camera rotates around the character in a clockwise direction and q rotates the camera around the character in a counterclockwise direction. I have this working with my floors and walls by translating to the character, doing the screen rotation, and drawing everything with the character as the origin. The problem arises when I shoot projectiles which need to both rotate around the character and rotate around themselves (shooting uses the mouse cursor so I can shoot at any angle). For example, if the screen is not rotated and I'm shooting rectangular projectiles, I want them to face in the direction I'm shooting (rotation around themselves). However if I only do this rotation, when I then rotate the screen the projectiles will always shoot at the same position because my cursor position does not change. Therefore I need to also either rotate the projectiles around the character or rotate the mouse cursor position to get the correct position (which would then totally screw up all of the collision detection). Likewise if I only do the screen rotation on projectiles, the rectangles will always be facing the same way and they would only look correct if I were shooting straight up or straight down. So my question is, how can I perform 2 rotations on a primitive around 2 different points? The only way I can think of is to translate to the character and do the screen rotation, then somehow calculate the translation required to move back to the middle of the projectile (seeing as how my axes are now rotated) and do its rotation. Or am I thinking about this in the wrong way and there is a different solution to accomplishing this effect?

• Is committing/checking in code everyday a good practice?

  - by ArtB

  I've been reading Martin Fowler's note on Continuous Integration and he lists as a must "Everyone Commits To the Mainline Every Day". I do not like to commit code unless the section I'm working on is complete and that in practice I commit my code every three days: one day to investigate/reproduce the task and make some preliminary changes, a second day to complete the changes, and a third day to write the tests and clean it up^ for submission. I would not feel comfortable submitting the code sooner. Now, I pull changes from the repository and integrate them locally usually twice a day, but I do not commit that often unless I can carve out a smaller piece of work. Question: is committing everyday such a good practice that I should change my workflow to accomodate it, or it is not that advisable? Edit: I guess I should have clarified that I meant "commit" in the CVS meaning of it (aka "push") since that is likely what Fowler would have meant in 2006 when he wrote this. ^ The order is more arbitrary and depends on the task, my point was to illustrate the time span and activities, not the exact sequence.

• How to tell your boss that he's a bad programmer? [closed]

  - by Doe

  Possible Duplicate: How to tell your boss that his programming style is really bad? There was a question about the boss having a bad programming style (weird booleans, empty loops, etc.) Having a bad/weird style does not imply being a bad programmer, but my situation is different. My boss outputs some really nasty code for the project, on which we are working together (just two of us). Examples: functions that span over several screens (big screens - 1900 x 1200) Deeply nested Conditional and Loop statements (up to 10 levels!!) Too much static variables, singletons, and both (singleton class with all the methods and members also static) Sometimes the code committed to the version control system does not even compile! Copy-Paste code instead of separating it into an independent function. Fail all the deadlines. "This's [C#|Java|Python] it shouldn't be efficient, that's why we loop all over the haystack to find the needle." "This's C/C++, it's fast enough to loop all over the haystack to find the needle." There is much more to mention... But the worst is that I have to redo much of the stuff he does, my code, which I try to keep clean is often polluted with above-mentioned atrocities. He's reaching 30 soon, so all his skills are established, and I don't even know if it's possible to change something. I like the project, but sometimes I just want to quit...

• How bad it's have two methods with the same name but differents signatures in two classes?

  - by Super User

  I have a design problem relationated with the public interface, the names of methods and the understanding of my API and my code. I have two classes like this: class A: ... function collision(self): .... ... class B: .... function _collision(self, another_object, l, r, t, b): .... The first class have one public method named collision and the second have one private method called _collision. The two methods differs in arguments type and number. In the API _m method is private. For the example let's say that the _collision method checks if the object is colliding with another_ object with certain conditions l, r, t, b (for example, collide the left side, the right side, etc) and returns true or false according to the case. The collision method, on the other hand, resolves all the collisions of the object with other objects. The two methods have the same name because I think is better avoid overload the design with different names for methods who do almost the same think, but in distinct contexts and classes. This is clear enough to the reader or I should change the method's name?

• Bizarre SSH Problem - It won't even start

  - by thallium85

  I recently got Ubuntu 12.04 Precise, got it up and running with some MediaWiki software, static IP on the box and router and was able to access the main page even from a cell phone. Everything seemed great... Then I wanted to finally get rid of the monitor and keyboard and login remotely via SSH. I installed openssh-server, let everything point to port 22 for a test run and installed putty on my Windows XP machine. I got a connection refused. Went back and started checking the Ubuntu install itself... (I'm under root from this point on) $ sudo -s $ service ssh status ssh stop/waiting $ service ssh start ssh start/running, process 2212 $ service ssh status ssh stop/waiting Apparently ssh has stopped or is waiting for something.... $ ssh localhost ssh: connect to host localhost port 22: Connection refused I can't even connect to myself... I checked ufw (firewall) to see if port 22 is doing alright... $ sudo ufw status Status: active To Action From 22 ALLOW Anywhere 22/tcp ALLOW Anywhere 22 ALLOW Anywhere (v6) 22/tcp ALLOW Anywhere (v6) sshd_config shows only Port 22 Is ssh not using the right IP address at all? I just don't get what I did wrong here. When this is up and running I will def change the port number, but for now, I don't want to mess with the default install too much until a test run with putty is successful. Edit: Here are my sshd_config file and my ssh_config file. The command /usr/sbin/sshd -p 22 -D -d -e returns: /etc/ssh/sshd_config line 159: Subsystem 'sftp' already defined. Edit: @phoibus moving the sshd_config file and reinstalling did the trick! service ssh status the above command shows that ssh is now running and I am now able to log in from my windows xp computer remotely via putty. Thanks so much! I can now use my monitor for other things!

• Falling CCSprites

  - by Coder404

  Im trying to make ccsprites fall from the top of the screen. Im planning to use a touch delegate to determine when they fall. How could I make CCSprites fall from the screen in a way like this: -(void)addTarget { Monster *target = nil; if ((arc4random() % 2) == 0) { target = [WeakAndFastMonster monster]; } else { target = [StrongAndSlowMonster monster]; } // Determine where to spawn the target along the Y axis CGSize winSize = [[CCDirector sharedDirector] winSize]; int minY = target.contentSize.height/2; int maxY = winSize.height - target.contentSize.height/2; int rangeY = maxY - minY; int actualY = (arc4random() % rangeY) + minY; // Create the target slightly off-screen along the right edge, // and along a random position along the Y axis as calculated above target.position = ccp(winSize.width + (target.contentSize.width/2), actualY); [self addChild:target z:1]; // Determine speed of the target int minDuration = target.minMoveDuration; //2.0; int maxDuration = target.maxMoveDuration; //4.0; int rangeDuration = maxDuration - minDuration; int actualDuration = (arc4random() % rangeDuration) + minDuration; // Create the actions id actionMove = [CCMoveTo actionWithDuration:actualDuration position:ccp(-target.contentSize.width/2, actualY)]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)]; [target runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; // Add to targets array target.tag = 1; [_targets addObject:target]; } This code makes CCSprites move from the right side of the screen to the left. How could I change this to make the CCSprites to move from the top of the screen to the bottom?

• Is there a canonical source supporting "all-surrogates"?

  - by user61852

  Background The "all-PK-must-be-surrogates" approach is not present in Codd's Relational Model or any SQL Standard (ANSI, ISO or other). Canonical books seems to elude this restrictions too. Oracle's own data dictionary scheme uses natural keys in some tables and surrogate keys in other tables. I mention this because these people must know a thing or two about RDBMS design. PPDM (Professional Petroleum Data Management Association) recommend the same canonical books do: Use surrogate keys as primary keys when: There are no natural or business keys Natural or business keys are bad ( change often ) The value of natural or business key is not known at the time of inserting record Multicolumn natural keys ( usually several FK ) exceed three columns, which makes joins too verbose. Also I have not found canonical source that says natural keys need to be immutable. All I find is that they need to be very estable, i.e need to be changed only in very rare ocassions, if ever. I mention PPDM because these people must know a thing or two about RDBMS design too. The origins of the "all-surrogates" approach seems to come from recommendations from some ORM frameworks. It's true that the approach allows for rapid database modeling by not having to do much business analysis, but at the expense of maintainability and readability of the SQL code. Much prevision is made for something that may or may not happen in the future ( the natural PK changed so we will have to use the RDBMS cascade update funtionality ) at the expense of day-to-day task like having to join more tables in every query and having to write code for importing data between databases, an otherwise very strightfoward procedure (due to the need to avoid PK colisions and having to create stage/equivalence tables beforehand ). Other argument is that indexes based on integers are faster, but that has to be supported with benchmarks. Obviously, long, varying varchars are not good for PK. But indexes based on short, fix-length varchar are almost as fast as integers. The questions - Is there any canonical source that supports the "all-PK-must-be-surrogates" approach ? - Has Codd's relational model been superceded by a newer relational model ?

• Routing tables don't show ppp0 after 12.04 kernel upgrade to 3.5.0: Haier CE682 modem configuration

  - by ubunsteve

  I'm trying to get my Haier CE682 EVDO modem, model number 201e:1022 to work in ubuntu 12.04 kernel 3.5.0-030500-generic #201207211835 . I had it working in a previous 12.04 kernel, using compat-wireless and these instructions http://zulkhamsyahmh.blogspot.com/2012/05/install-smartfren-haier-ce682-on-ubuntu.html, and to get it working had to edit the routing tables so that there was a ppp0 showing up, as suggested at http://www.linuxquestions.org/questions/slackware-14/wvdial-is-connecting-but-im-unable-to-do-anything-714861/ Network manager doesn't work with this modem, so I use either wvdial or gpppon to connect to it, both which work (after I run the command sudo modprobe usbserial vendor=0x201e product=0x1022 ) This is the output of when I connect with gpppon to the modem: Using interface ppp0 Connect: ppp0 <-- /dev/ttyUSB0 sent [LCP ConfReq id=0x1 ] rcvd [LCP ConfAck id=0x1 ] rcvd [LCP ConfReq id=0x2 ] sent [LCP ConfAck id=0x2 ] sent [LCP EchoReq id=0x0 magic=0x819c86db] rcvd [CHAP Challenge id=0x1 <1ac8f12799e953967a3cc222c9254690, name = ""] sent [CHAP Response id=0x1 <6f12a903dc40915ca2761c17b87f8fbd, name = "smart"] rcvd [LCP EchoRep id=0x0 magic=0x0] rcvd [CHAP Success id=0x1 ""] CHAP authentication succeeded CHAP authentication succeeded sent [CCP ConfReq id=0x1 ] sent [IPCP ConfReq id=0x1 ] rcvd [IPCP ConfReq id=0x1 ] sent [IPCP ConfAck id=0x1 ] rcvd [CCP ConfReq id=0x1] sent [CCP ConfAck id=0x1] rcvd [CCP ConfRej id=0x1 ] sent [CCP ConfReq id=0x2] rcvd [IPCP ConfRej id=0x1 ] sent [IPCP ConfReq id=0x2 ] rcvd [CCP ConfAck id=0x2] rcvd [IPCP ConfNak id=0x2 ] sent [IPCP ConfReq id=0x3 ] rcvd [IPCP ConfAck id=0x3 ] not replacing existing default route via 192.168.3.1 local IP address 10.191.248.154 remote IP address 10.17.95.25 primary DNS address 10.17.3.244 secondary DNS address 10.17.3.245 as you can see there is a problem with "not replacing existing default route via 192.168.3.1" This it the out put of route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.3.1 0.0.0.0 UG 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.3.0 * 255.255.255.0 U 2 0 0 wlan0 I had tried these commands, which had previously worked in the earlier kernel: route del default route add default ppp0 but that broke my wireless internet connection. I then added the default routing as shown above with sudo route add default gw 192.168.3.1 wlan0 So it seems I need to add or change the routing to show a ppp0 connection, but I don't know how to do that.

• Am I an idealist?

  - by ereOn

  This is not only a question, this is also a call for help. Since I started my career as a programmer, I always tried to learn from my mistakes. I worked hard to learn best-practices and while I don't consider myself a C++ expert, I still believe I'm not a beginner either. I was recently hired into a company for C++ development. There I was told that my way to work was "against the rules" and that I would have to change my mind. Here are the topics I disagree with my hierarchy (their words): "You should not use separate header files for your different classes. One big header file is both easier to read and faster to compile." "Trying to use different headers is counter-productive : use the same super-set of headers everywhere, and enforce the use #pragma hdrstop to hasten compilation" "You may not use Boost or any other library that uses nested directories to organize its files. Our build-machine doesn't work with nested directories. Moreover, you don't need Boost to create great software." One might think I'm somehow exaggerated things, but the sad truth is that I didn't. That's their actual words. I believe that having separate files enhance maintainability and code-correctness and can fasten compilation time by the use of the proper includes. Have you been in a similar situation? What should I do? I feel like it's actually impossible for me to work that way and day after day, my frustration grows.

• Removing spam external links after pharma hack?

  - by Beatchef

  Back in February my work's site was attacked by a pharma hack at the shared hosting end. I managed to find the placed file and the reference to run it in one of our files. I deleted this file, deleted and redownloaded all of the plugins and themes and reinstalled Wordpress. However I could never find the database entries no matter what I have read up on. Searching for known entries or for drug names backwards etc. On the Google and Bing end I have managed to deny and delete the entries and cache of most if not all of the bad links that the hack managed to instantly SEO to death (why don't these guys work legit and make more money?) However the one thing that is remaining is external links on the homepage that are invisible except when the site is viewed in google cache or scanned with unmaskparasites.com (and says that the external links are safe even though they're obviously not!). http://www.UnmaskParasites.com/security-report/?page=kmcharityteam.co.uk All sorts of website scans say there's nothing wrong with it and I can't find the source of the links in the header or footer or anywhere in the theme. I've searched for the links in the database but no use there either and they change every day so really I'd have to be looking for a generator? Does anybody have any advice or a solution for removing these links? Thanks!

• Installing Ubuntu Server 12.04 as a software RAID 1 mirror fails to boot

  - by Jeff Atwood

  I'm installing a few new Ubuntu Server 12.04 LTS servers, and they have two 512 GB SSDs. I want them to use software RAID 1 mirroring, so I was following this document religiously step by step: https://help.ubuntu.com/12.04/serverguide/advanced-installation.html To summarize the above official documentation: to set up a software RAID 1 mirror in Ubuntu Server, you choose manual partitioning during the setup, and do this on each drive: "swap" partition of roughly RAM size "physical volume for RAID" partition for remaining drive size After that, you set up the RAID 1 mirror using the RAID partitions on drive A and B, make it ext4 and containing the root filesystem partition. Setup continues from there just fine. One caveat: I was completely unable to select the "physical volume for RAID" as bootable. When I tried to do that in setup, it had no effect: I could press enter on the "make bootable" option all day long and nothing would ever change. However, after install successfully completes, I have a big problem: the system won't boot! I get Reboot and Select proper boot device or Insert Boot Media in selected Boot device and press a key What did I do wrong? Why can't I mark that "physical volume for RAID" partition bootable during Ubuntu Server setup? Is there some way for me to make the physical volumes for RAID bootable after the fact, perhaps from a live CD or something?

• Should we test all our methods?

  So today I had a talk with my teammate about unit testing. The whole thing started when he asked me "hey, where are the tests for that class, I see only one?". The whole class was a manager (or a service if you prefer to call it like that) and almost all the methods were simply delegating stuff to a DAO so it was similar to: SomeClass getSomething(parameters) { return myDao.findSomethingBySomething(parameters); } A kind of boilerplate with no logic (or at least I do not consider such simple delegation as logic) but a useful boilerplate in most cases (layer separation etc.). And we had a rather lengthy discussion whether or not I should unit test it (I think that it is worth mentioning that I did fully unit test the DAO). His main arguments being that it was not TDD (obviously) and that someone might want to see the test to check what this method does (I do not know how it could be more obvious) or that in the future someone might want to change the implementation and add new (or more like "any") logic to it (in which case I guess someone should simply test that logic). This made me think, though. Should we strive for the highest test coverage %? Or is it simply an art for art's sake then? I simply do not see any reason behind testing things like: getters and setters (unless they actually have some logic in them) "boilerplate" code Obviously a test for such a method (with mocks) would take me less than a minute but I guess that is still time wasted and a millisecond longer for every CI. Are there any rational/not "flammable" reasons to why one should test every single (or as many as he can) line of code?

• IE8 HTTPs Download Issue

  - by Jon Egerton

  I have a problem with a system I develop related to IE8 downloading over SSL (ie on sites using https://...) and is described on this MS kb article: http://support.microsoft.com/kb/323308 We use the HTTPCacheability.NoCache option as the data being downloaded is sensitive, and is downloaded from a secured site. I don't want that data to be cached on any of the proxies etc that the response passes through back to the client. The article describing the issue details a fix to the client side registry changing a BypassSSLNoCacheCheck setting. I don't want to loosen the system security just for IE8, as the system works fine on anything more upto date. Getting all the clients to apply the hotfix is difficult at best, and impossible at worst. We need to support IE8 in the system, at least for now. So: 1: Does the detailed hotfix have any implications for the security at the browser end in IE8 - does it mean the file will be cached? (in a place other than where the user saves the file). 2: Is there some way I can get these files downloadable with a change at the server end that doesn't break the security side of things?

• Media Drive Permissions

  - by Wade Wofford

  I just switched from a Hackintosh to Linux, and am trying to make sense of it. On my hackintosh, I partitioned a big drive into 3 parts--1 which holds music, 1 for film/tv, and one for the OS. I installed Ubuntu onto the OS partition, and am now trying to make it so I can write to the media drives. I've searched around and tried several things. I tried gksu nautilus in Terminal, which brought me into root permissions. When I select a folder and try to change permissions, I get "The owner could not be changed...Error setting owner: Read-only file system" Ultimately, I have two specific aims: - I want to make it so I can write to the film/tv drive from the ubuntu machine only - I want to make it so I can write to the music drive from the ubuntu machine, or any other machine on the network (all Macs). That is, I want a single music library (an iTunes file) that will serve all Mac laptops/iPads/iPhones on the network, but which XBMC on the Ubuntu machine can also see / read from. Music will be added to the iTunes library via a single Mac laptop, but all other devices should be able to see the music drive.

• Dual monitors with one above the other?

  - by Felix

  I'm using Gnome 3 and proprietary Nvidia drivers. I have tried to set in nvidia-settings my external monitor to be "above" my main one (it's a laptop). However, when I try to drag a window up from the main display to the external one, it gets stuck and can't move past a certain point. Trying to maximize it changes its decoration so it looks maximized (i.e. no borders, etc), but its size or position doesn't change. Now, if I set my external monitor to be "to the left" of the main one, it works, which is why I'm suspecting this is a Gnome issue, not an Nvidia one. Anyone know how to fix this? Update: some versions: Gnome: 3.2.2.1 Nvidia: 280.13 Update 2: I can see that Gnome 3.4 is out, and among the release notes is better external monitor support. However, they only mention a small fix that is unrelated to my problem. Can anyone with Gnome 3.4 and access to an external monitor please test this out and tell me if it works? I don't want to go through the hassle of upgrading my Ubuntu installation unless I know for certain it's going to fix the problem.

• Using HTML5 Today part 4&ndash;What happened to XHTML?

  - by Steve Albers

  This is the fourth entry in a series of descriptions & demos from the “Using HTML5 Today” user group presentation. For practical purposes, the original XHTML standard is a historical footnote, although XHTML transitional will probably live on forever in the default web page templates of old web page editors. The original XHTML spec was released in 2000, on the heels of the HTML 4.01 spec.  The plan was to move web development away from HTML to the more formal, rigorous approach that XHTML offered, but it was built on a principle that conflicts with the history and culture of the Internet: XHTML introduced the idea of Draconian Error Handling, which essentially means that invalid XML markup on a page will cause a page to stop rendering. There is a transitional mode offered in the original XHTML spec, but the goal was to move to D.E.H.  You can see the result by changing the doc type for a document to “application/xhtml+xml” - for my class example we change this setting in the web.config file: <staticContent> <remove fileExtension=".html" /> <mimeMap fileExtension=".html" mimeType="application/xhtml+xml" /> </staticContent> With the new strict syntax a simple error, in this case a duplicate </td> tag, can cause a critical page error: While XHTML became very popular in the ensuing decade, the Strict form of XHTML never achieved widespread use. Draconian Error Handling was one of the factors that led in time to the creation of the WHATWG, or Web Hypertext Application Technology Group.  WHATWG contributed to the eventually disbanding of the XHTML 2.0 working group and the W3C’s move to embrace the HTML5 standard. For developers who long for XML markup the W3C HTML5 standard includes an XHTML5 syntax. For the longer, more definitive look at what happened to XHTML and how HTML5 came to be check out the Dive Into HTML mirror site or Bruce Lawson’s “HTML5: Who, What, When Why” talk.

• Ubuntu 12, chromium/chrome facebook not loading

  - by Grant

  this problem started with chrome, tried chromium to fix it. both have this problem, and after installed firefox no longer works with facebook. I found a threas with two fixes that work and what I need to know is how to make these fixes permanent. one is a cache permissions workaround. launching chromium from terminal with a redirect to a new self created cache in the home folder works. how can i repair the permissions issue with the cache or make a permanent change to the cache chromium uses? two, the ifconfig wlan0 mtu set to 1492, this setting doesnt seem to be perpetual after a reboot. this set of issues is I believe specific to my particular install as there isnt a huge issue from anyone else out there, i'm on a toshiba satellite laptop with a 50/50 HDD partition split with windows. This is likely causing the issue or contributing in some way but I wont run linux full time on this machine until I get these kinks a more permanent fix. Thanks in advance for any advice/answers.

• How can I mark a pixel in the stencil buffer?

  - by János Turánszki

  I never used the stencil buffer for anything until now, but I want to change this. I have an idea of how it should work: the gpu discards or keeps rasterized pixels before the pixel shader based on the stencil buffer value on the given position and some stencil operation. What I don't know is how would I mark a pixel in the stencil buffer with a specific value. For example I draw my scene and want to mark everything which is drawn with a specific material (this material could be looked up from a texture so ideally I should mark the pixel in the pixel shader), so that later when I do some post processing on my scene I would only do it on the marked pixels. I didn't find anything on the internet besides how to set up a stencil buffer and explaining the different stencil operations. I was expecting to find some System-Value semantics like SV_Depth to write to in the pixel shader (because the stencil buffer shares the same resource with the depth buffer in D3D11), but there is no such thing on MSDN. So how should I do this? If I am misunderstanding something please help me clear that up.

• Limiting calls to WCF services from BizTalk

  - by IntegrationOverload

  ** WORK IN PROGRESS ** This is just a placeholder for the full article that is in progress. The problem My BTS solution was receiving thousands of messages at once. After processing by BTS I needed to send them on via one of several WCF services depending on the message content. The problem is that due to the asynchronous nature of BizTalk the WCF services were getting hammered and could not cope with the load. Note: It is possible to limit the SOAP calls in the BtsNtSvc.exe.Config file but that does not have the desired results for Net-TCP WCF services. The solution So I created a new MessageType for the messages in question and posted them to the BTS messaeg box. This schema included the URL they were being sent to as a promoted property. I then subscribed to the message type from a new orchestraton (that does just the WCF send) using the URL as a correlation ID. This created a singleton orchestraton that was instantiated when the first message hit the message box. It then waits for further messages with the same correlation ID and type and processs them one at a time using a loop shape with a timer (A pretty standard pattern for processing related messages) Image to go here This limits the number of calls to the individual WCF services to 1. Which is a good start but the service can handle more than that and I didn't want to create a bottleneck. So I then constructed the Correlation ID using the URL concatinated with a random number between 1 and 10. This makes 10 possible correlation IDs per URL and so 10 instances of the singleton Orchestration per WCF service. Just what I needed and the upper random number is a configuration value in SSO so I can change the maximum connections without touching the code.

• Adsense: You have rejected ad requests, which will result in lost revenue

  - by Chankey Pathak

  Got an alert on my adsense account which says You have rejected ad requests, which will result in lost revenue. The following ad units have made ad requests with incorrect site information. This occurs when the URL of the server from which the ad unit has been served differs from the URL of the actual page where the ad will be displayed. Learn how to fix these errors. So the solution is that I'll have to use "google_page_url = "http://myurl.com/fullpath";" I'm using wordpress, what should be the URL for google_page_url? For example my website is www.technostall.com. Should I put www.technostall.com there or should I give the path of each post? That is not good because I'm using a sidebar widget for sidebar ad unit. I can't change google_page_url for each page. What should I do? This error is appearing only on my sidebar/navigation ad units. Is using google_page_url = document.location; fine?

• Halloween: Season for Java Embedded Internet of Spooky Things (IoST) (Part 5)

  - by hinkmond

  So, here's the finished product. I have 8 networked Raspberry Pi devices strategically placed around our Oracle Santa Clara Building 21 office. I attached a JFET transistor based EMF sensor on each device to capture any strange fluctuations in the electromagnetic field (which supposedly, paranormal spirits can change as they pass by). And, I have have a Web app (embedded in this page) which can take the readings and show a graphical display in real-time. As you can see, all the Raspberry Pi devices are blinking away green, indicating they are all operational and all sensors are working correctly. But, I don't see anything... Darn... Maybe, I have to stare at the Web app for a while. I don't know when the "alleged" ghosts in our Oracle Santa Clara office are supposed to be active, but let me know if you see anything... Oh, and by the way, Happy Halloween from the Internet of Spooky Things!

• TraceTune: Larger Files and History

  - by Bill Graziano

  I updated TraceTune over the weekend.  I increased the trace file upload size to 20MB.  We’ve processed over half a million rows of trace data so far and I’m confident this won’t kill the server. I added average CPU and average disk reads to the screen that lists the SQL statements in a trace file. I only added these two.  I’m pretty sure average writes isn’t that import.  I’m still thinking about average duration.  I’m trying to balance showing you what you need with a clean, simple interface.  Plus I have a way to see the averages that I describe further down. TraceTune now keeps the last 10 files that you’ve uploaded and will give you some basic details about each file. I think the last change I made is the most interesting. For each SQL statement, I show the history of that statement. You’ll see each trace file where this statement was found.  It will list the averages for CPU, reads, writes and duration.  This will quickly show you if you’re improving the performance of that query.  In my screen shot above you can that even though the execution counts are very different the averages are consistent. If you want to see what queries are consuming the most resources on your server give TraceTune a try.

• TransformXml Task locks config file identified in Source attribute

  - by alexhildyard

  As background: the TransformXml MSBuild task is typically invoked in a custom build step to mark up a web.config file with per-environment configuration; its flexible directives offer highly granular control over the insertion, removal, substitution and transformation of existing configuration hierarchies. For those using the TransformXML task (typically in a Web Deployment Project) I raised an issue against Visual Studio 2010, in which the file handle on the input file was not released, meaning that following transformation the source file remained locked. As a result, the best way to transform a file was first to rename it, transform it, and then copy it back, leaving the "locked" file to be freed up later.I just heard today that this has now been resolved in Visual Studio 2012 RTM. That's good news, because Web Config Transformations offer a lot. An intelligent, automated build process will swap in the relevant transform(s), making it much easier to synthesise the Developer and Build server builds. This makes for a simpler and more exemplary build process, and with the tighter coupling comes a correspondingly quicker response to Developmental change.Oh, and don't forget -- it isn't just web.configs you can transform. You can transform app.configs, or indeed any XML file that honours the task's schema and hierarchical rules.
