  • Representing Mauritius in the 2013 Bench Games

    Only by chance I came across an interesting option for professionals and enthusiasts in IT, and quite honestly I can't even remember where I caught attention of Brainbench and their 2013 Bench Games event. But having access to 600+ free exams in a friendly international intellectual competition doesn't happen to be available every day. So, it was actually a no-brainer to sign up and browse through the various categories. Most interestingly, Brainbench is not only IT-related. They offer a vast variety of fields in their Test Center, like Languages and Communication, Office Skills, Management, Aptitude, etc., and it can be a little bit messy about how things are organised. Anyway, while browsing through their test offers I added a couple of exams to 'My Plan' which I would give a shot afterwards. Self-assessments Actually, I took the tests based on two major aspects: 'Fun Factor' and 'How good would I be in general'... Usually, you have to pay for any kind of exams and given this unique chance by Brainbench to simply train this kind of tests was already worth the time. Frankly speaking, the tests are very close to the ones you would be asked to do at Prometric or Pearson Vue, ie. Microsoft exams, etc. Go through a set of multiple choice questions in a given time frame. Most of the tests I did during the Bench Games were based on 40 questions, each with a maximum of 3 minutes to answer. Ergo, one test in maximum 2 hours - that sounds feasible, doesn't it? The Measure of Achievement While the 2013 Bench Games are considered a worldwide friendly competition of knowledge I was really eager to get other Mauritians attracted. Using various social media networks and community activities it all looked quite well at the beginning. Mauritius was listed on rank #19 of Most Certified Citizens and rank #10 of Most Master Level Certified Nation - not bad, not bad... Until... the next update of the Bench Games Leaderboard. The downwards trend seemed to be unstoppable and I couldn't understand why my results didn't show up on the Individual Leader Board. First of all, I passed exams that were not even listed and second, I had better results on some exams listed. After some further information from the organiser it turned out that my test transcript wasn't available to the public. Only then results are considered and counted in the competition. During that time, I actually managed to hold 3 test results on the Individuals... Other participants were merciless, eh, more successful than me, produced better test results than I did. But still I managed to stay on the final score board: An 'exotic' combination of exam, test result, country and person itself Representing Mauritius and the Visual FoxPro community in that fun event. And although I mainly develop in Visual FoxPro 9.0 SP2 and C# using .NET Framework from 2.0 to 4.5 since a couple of years I still managed to pass on Master Level. Hm, actually my Microsoft Certified Programmer (MCP) exams are dated back in June 2004 - more than 9 years ago... Look who got lucky... As described above I did a couple of exams as time allowed and without any preparations, but still I received the following mail notification: "Thank you for recently participating in our Bench Games event.  We wanted to inform you that you obtained a top score on our test(s) during this event, and as a result, will receive a free annual Brainbench subscription.  Your annual subscription will give you access to all our tests just like Bench Games, but for an entire year plus additional benefits!" -- Leader Board Notification from Brainbench Even fun activities get rewarded sometimes. Thanks to @Brainbench_com for the free annual subscription based on my passed 2013 Bench Games Master Level exam. It would be interesting to know about the total figures, especially to see how many citizens of Mauritius took part in this year's Bench Games. Anyway, I'm looking forward to be able to participate in other challenges like this in the future.

  • Selenium Webdrivers: Load Page without any resources

    - by Biffy
    I am trying to prevent Javascript from changing the site's source code I'm testing with Selenium. The problem is, I can't just simply turn Javascript off in the Webdriver, because I need it for a test. Here's what I'm doing for the Firefox Webdriver: firefoxProfile.setPreference("permissions.default.image", 2); firefoxProfile.setPreference("permissions.default.script", 2); firefoxProfile.setPreference("permissions.default.stylesheet", 2); firefoxProfile.setPreference("permissions.default.subdocument", 2); I don't allow Firefox to load any Images, Scripts and Stylesheets. How can I do this with the Internet Explorer Webdriver and the Chrome Webdriver? I have not found any similar preferences. Or is there even a more elegant way to stop the webdrivers from loading the site's JS Files after all? Thank you!

  • Git: Remove specific commit

    - by Joshua Cheek
    I was working with a friend on a project, and he edited a bunch of files that shouldn't have been edited. Somehow I merged his work into mine, either when I pulled it, or when I tried to just pick the specific files out that I wanted. I've been looking and playing for a long time, trying to figure out how to remove the commits that contain the edits to those files, it seems to be a toss up between revert and rebase, and there are no straightforward examples, and the docs assume I know more than I do. So here is a simplified version of the question: Given the following scenario, how do I remove commit 2? $ mkdir git_revert_test && cd git_revert_test $ git init Initialized empty Git repository in /Users/josh/deleteme/git_revert_test/.git/ $ echo "line 1" > myfile $ git add -A $ git commit -m "commit 1" [master (root-commit) 8230fa3] commit 1 1 files changed, 1 insertions(+), 0 deletions(-) create mode 100644 myfile $ echo "line 2" >> myfile $ git commit -am "commit 2" [master 342f9bb] commit 2 1 files changed, 1 insertions(+), 0 deletions(-) $ echo "line 3" >> myfile $ git commit -am "commit 3" [master 1bcb872] commit 3 1 files changed, 1 insertions(+), 0 deletions(-) The expected result is $ cat myfile line 1 line 3 Here is an example of how I have been trying to revert $ git revert 342f9bb Automatic revert failed. After resolving the conflicts, mark the corrected paths with 'git add <paths>' or 'git rm <paths>' and commit the result.

  • Any task-control algorithms programming practices?

    - by NumberFour
    Hi, I was just wondering if there's any field which concerns the task-control programming (or at least that's the way I call it). For a better explanation of task-control consider the following scenario: An application (master-thread) waits for a command - which might be a particular action or a set of actions the application should perform. When a command is received the master-thread creates a task (= spawns an independent thread which actually does the action) and adds a record in it's task-list - thus keeping track of the time of execution, thread handle, task priority...etc. The master-thread awaits for any other incoming commands while taking care of all the tasks - e.g: kills tasks running too long, prioritizes tasks with higher priorities, kills a task on a request of another task, limits the number of currently running tasks, allows task scheduling, cleans finished tasks (threads) and so on. The model is pretty similar to what we can see in OS dealing with running processes. Are there any good practices programming such task-models or is there some theoretical work done in this field? Maybe my question is too generalized, but at least I wanted to know whether there are any experiences working on such models or if there's a better approach. Thanks for any answers.

  • Using db4o with multiple application instances under medium trust

    - by Anders Fjeldstad
    I recently stumbled over the object database engine db4o which I think looks really interesting. I would like to use it in an ASP.NET MVC application that will be deployed to a shared hosting environment under medium trust. Because of the trust level, I'm restricted to using db4o in embedded/in-process mode. That in itself should be no problem, but the hosting provider also transparently runs each web application in multiple (load-balanced) server instances with shared storage, which I would say is normally a very nice feature for a $10/month hoster. However, since an instance of a db4o server with write access (whether in-process or networked) locks the underlying database file, having multiple instances of the application using the same file won't work (or at least I can't see how it would). So the question is: is it possible to use db4o in this specific environment? I have considered letting each application have its own database which is synchronized with a master database using replication (dRS), but that approach will most likely end up with very frequent bi-directional replication (read master changes at beginning of each request, write to master after each change) which I don't think will be very efficient. Summary of the web application/environment characteristics: Read-intensive (but not entirely read-only) Some delay (a few seconds) is acceptible between the time that a change is made and the time when the change shows up in all the application instances' data Must run in medium trust No guarantee that the load-balancer uses "sticky sessions" All suggestions are much appreciated!

  • Cloning git repository from svn repository, results in file-less, remote-branch-less git repo.

    - by ObjectiveJ
    I have set up the screenshot plugin from github, located here: https://github.com/phonegap/phonegap-plugins/tree/master/Android/Screenshot I set it up as instructed and with 1.8.1 of cordova. It worked and the screenshot was saved to the phone. However it fails with cordova 2.0.0. Screenshot.java code: https://github.com/phonegap/phonegap-plugins/blob/master/Android/Screenshot/src/org/apache/cordova/Screenshot.java Screenshot.js code: https://github.com/phonegap/phonegap-plugins/blob/master/Android/Screenshot/www/Screenshot.js Due to the advice of a very clever man called Simon MacDonald, I removed line 31 and 38 from the JS file shown above. However when I try to use the screenshot plugin with cordova 2.0.0 I receive these errors: ERROR: org.json.JSONException: Value undefined of type java.lang.String cannot be converted to JSONArray.

  • Right-Align and Vertical Align label with checkbox/radio button CSS

    - by Jon
    Hi Everyone, I'm very close and have this working in Safari, Firefox and IE8, however IE7 the labels and radio buttons do not align vertically. My HTML is: <div id="master-container"> <fieldset id="test"> <legend>This is a test of my CSS</legend> <ul class="inputlist"> <li> <label for="test1">Test 1</label> <input name="test1" id="test1" type="checkbox" disabled="disabled"/> </li> <li> <label for="test2">Test 2</label> <input name="test2" id="test2" type="checkbox" disabled="disabled"/> </li> </ul> </fieldset> </div> My CSS Is: html{font-family:Arial,Helvetica,sans-serif;} #master-container{width:615px;font-size:12px;} ul.inputlist{list-style-type:none;} ul.inputlist li{width:100%;margin-bottom:5px;} ul.inputlist li label{width:30px; text-align:right; margin-right:7px;float:left;} Any suggestions? Thanks! EDIT: Based on the suggestion to check the rest of my html and css. I updated the code above and now it accurately demonstrates the problem. If I take font-size out of #master-container it lines up but then it is not the proper font-size. I tried to add a font-size to ul.inputlist li input but that didn't help. Any suggestions? Thanks for your help everyone!

  • TeamCity and pending Git merge branch commit keeps build with failed tests

    - by Vladimir
    We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

  • Pushing to bare Git repository (remote) causes it to stop being bare

    - by NSD
    I have a local repository called TestRepo. I clone it with the --bare option, zip this clone up, and throw it on my server. Unzip it, and it's still bare. I then clone the bare remote repository locally over ssh with something like git clone ssh://[email protected]/~/TestRepo.git TestRepoCloned The local TestRepoCloned is not bare and has a remote called "origin." It appears to be tracking correctly from the looks of its config file [core] repositoryformatversion = 0 filemode = true bare = false logallrefupdates = true ignorecase = true [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = ssh://[email protected]/~/TestRepo.git [branch "master"] remote = origin merge = refs/heads/master I edit an existing file. I commit the change to the current branch (master) via git commit -a -m "Edited a file." The commit succeeds and all is well. I decide to push this change to the remote repository via SSH with a git push The remote repository is now no longer bare, but has a complete working directory, and I get continuous error messages on all further attempts to push to it. Everything I've read seems to suggest that what I'm doing is correct, but it simply is not working. How am I supposed to push changes to a bare remote repo and actually keep it bare?

  • git workflow incorporating many, but not all commits from many forks

    - by becomingGuru
    I have a git repo. It has been forked several times and many independent commits are made on top of it. Everything normal, like what happens in many github hosted projects. Now, what exact workflow should I follow, if I want to see all that commits individually and apply the ones I like. The workflow I followed, which is not the optimal is to create a branch of the name github-username and merge the changes into my master and undo any changes in the commit I dont need manually (there are not many, so it worked). What I want is the ability to see all commits from different forks individually and cherry pick and apply them on top of my master. What is the workflow to follow for that? And what gui (gitk?) enables me to see all different individual commits. I realize that merge should be a primary part of the workflow and not cherry-pick as it creates a different commit (from git's point of view). Even rebasing other's changes on top of mine might not preserve the history on the graph to indicate that it is his commits I have rebased. So then, How do I ignore just a few commits from a lot of them? I think github should have a "apply this commit on top of my master" thing in their graph after each commit node; so I can just pull it, after doing all that.

  • git merge with renamed files

    - by Kevin
    I have a large website that I am moving into a new framework and in the process adding git. The current site doesn't have any version control on it. I started by copying the site into a new git repository. I made a new branch and made all of the changes that were needed to make it work with the new framework. One of those steps was changing the file extension of all of the pages. Now in the time that I have been working on the new site changes have been made to files on the old site. So I switched to master and copied all of those changes in. The problem is when I merge the branch with the new framework back onto master there is a conflict on every file that was changed on the master branch. I wouldn't be to worried about it but there are a couple of hundred files with changes. I have tried git rebase and git rebase --merge with no luck. How can I merge these 2 branches without dealing with every file?

  • PL/SQL - How to pull data from 3 tables based on latest created date

    - by Nancy
    Hello, I'm hoping someone can help me as I've been stuck on this problem for a few days now. Basically I'm trying to pull data from 3 tables in Oracle: 1) Orders Table 2) Vendor Table and 3) Master Data Table. Here's what the 3 tables look like: Table 1: BIZ_DOC2 (Orders table) OBJECTID (Unique key) UNIQUE_DOC_NAME (Document Name i.e. ORD-005) CREATED_AT (Date the order was created) Table 2: UDEF_VENDOR (Vendors Table): PARENT_OBJECT_ID (This matches up to the ObjectId in the Orders table) VENDOR_OBJECT_NAME (This is the name of the vendor i.e. Acme) Table 3: BIZ_UNIT (Master Data table) PARENT_OBJECT_ID (This matches up to the ObjectID in the Orders table) BIZ_UNIT_OBJECT_NAME (This is the name of the business unit i.e. widget A, widget B) Note: The Vendors Table and Master Data do not have a link between them except through the Orders table. I can join all of the data from the tables and it looks something like this: Before selecting latest order date: ORD-005 | Widget A | Acme | 3/14/10 ORD-005 | Widget B | Acme | 3/14/10 ORD-004 | Widget C | Acme | 3/10/10 Ideally I'd like to return the latest order for each vendor. However, each order may contain multiple business units (e.g. types of widgets) so if a Vendor's latest record is ORD-005 and the order contains 2 business units, here's what the result set should look like by the following columns: UNIQUE_DOC_NAME, BIZ_UNIT_OBJECT_NAME, VENDOR_OBJECT_NAME, CREATED_AT After selecting by latest order date: ORD-005 | Widget A | Acme | 3/14/10 ORD-005 | Widget B | Acme | 3/14/10 I tried using Select Max and several variations of sub-queries but I just can't seem to get it working. Any help would be hugely appreciated!

These wires all need to have their voltage read at the same time. More than a few hundred microseconds difference between the readings of each wire will completely screw it up. The Arduino takes about 114 microseconds. So the most I could read is 2 or 3 wires before the latency would skew the accuracy of the readings. So my plan is to have an Arduino as the "master" of an array of ATTinys. The arduino is pretty cramped for space, but it's a massive playground compared to the tinys. An ATTiny13A has 1k of flash ROM(program space), 64 bytes of RAM, and 64 bytes of (not-durable and slow) EEPROM. (I'm choosing this for price as well as size) The ATTinys in my system will not do much. Basically, all they will do is wait for a signal from the Master, and then read the voltage of 1 or 2 wires and store it in RAM(or possibly EEPROM if it's that cramped). And then send it to the Master using only 1 wire for data.(no room for more than that!). So far then, all I should have to do is implement trivial voltage reading code (using built in ADC). But this communication bit I'm worried about. Do you think a communication protocol(using just 1 wire!) could even be implemented in such constraints? TL;DR: In less than 1k of program space and 64 bytes of RAM(and 64 bytes of EEPROM) do you think it is possible to implement a 1 wire communication protocol? Would I need to drop to assembly to make it fit? I know that currently my Arduino programs linking to the Wiring library are over 8k, so I'm a bit concerned.

  • System.out.println() does not operate in Akka actor

    - by faisal abdulai
    I am kind of baffled by this encointer. I am working an akka project that was created as a maven projecct and imported into eclipse using the mvn eclipse:eclipse command. the akka actor has the system println method just to make it easy to do read the functions and methods invoked. However any time I run the akka system, the println command does not print any thing to the eclipse console but I do not get any error messages. does any one have any idea about this. below is a code snippet. public class MasterActor extends UntypedActor { /** * */ ActorSystem system = ActorSystem.create("container"); ActorRef worker1; //public MasterActor(){} @Override public void onReceive(Object message) throws Exception { System.out.println(" Master Actor 5"); if(message instanceof GesturePoints) { //GesturePoints gp = (GesturePoints) message; System.out.println(" Master Actor 1"); try { worker1.tell(message, getSelf()); System.out.println(" Master Actor 2"); } catch (Exception e) { getSender().tell(new akka.actor.Status.Failure(e), getSelf()); throw e; } } else{ unhandled(message);} } public void preStart() { worker1 = getContext().actorFor("akka://[email protected]:2553/user/workerActor"); } } don't know whether it is a bug in eclipse. thank you.

  • Can I rename LOCAL, REMOTE and BASE as used in git mergetool?

    - by carleeto
    Lets say I'm doing a rebase B of a branch onto master and there's a conflict. git opens up the default merge tool with 3 files as input : file.LOCAL, file.BASE, file.REMOTE (they're named a little differently, but LOCAL, BASE and REMOTE are in the file names and is how they are distinguished). Now, according to the mergetool man page: $LOCAL is set to the name of a temporary file containing the contents of the file on the current branch; $REMOTE set to the name of a temporary file containing the contents of the file to be merged, and $BASE set to the name of a temporary file containing the common base for the merge. That really does not make sense to me. LOCAL is the current state of the branch. Where I get lost is BASE and REMOTE. So my question is : Is it possible to make git use the branch name instead of LOCAL and similarly more meaningful names other than BASE and REMOTE? For example, if the branch name is FeatureX and the BASE = the file as it exists in master, is there a way to get git to substitute FeatureX for LOCAL and master for BASE, so that it is more apparent where the source is coming from? This is especially a problem when doing a rebase.

  • Microsoft Reporting: Setting subreport parameters in code

    - by Svish
    How can I set a parameter of a sub-report? I have successfully hooked myself up to the SubreportProcessing event, I can find the correct sub-report through e.ReportPath, and I can add datasources through e.DataSources.Add. But I find no way of adding report parameters?? I have found people suggesting to add them to the master report, but I don't really want to do that, since the master report shouldn't have to be connected to the sub-report at all, other than that it is wrapping the sub-report. I am using one report as a master template, printing name of the report, page numbers etc. And the subreport is going to be the report itself. And if I could only find a way to set those report parameters of the sub-report I would be good to go... Clarification: Creating/Defining the parameters is not the problem. The problem is to set their values. I thought the natural thing to do was to do it in the SubreportProcessing event. And the SubreportProcessingEventArgs do in fact have a Parameters property. But it is read only! So how do you use that? How can I set their value?

  • Importing hibernate configuration file into Spring applicationContext

    - by Himanshu Yadav
    I am trying to integrate Hibernate 3 with Spring 3.1.0. The problem is that application is not able to find mapping file which declared in hibernate.cfg.xml file. Initially hibernate configuration has datasource configuration, hibernate properties and mapping hbm.xml files. Master hibernate.cfg.xml file exist in src folder. this is how Master file looks: <hibernate-configuration> <session-factory> <!-- Mappings --> <mapping resource="com/test/class1.hbm.xml"/> <mapping resource="/class2.hbm.xml"/> <mapping resource="com/test/class3.hbm.xml"/> <mapping resource="com/test/class4.hbm.xml"/> <mapping resource="com/test/class5.hbm.xml"/> Spring config is: <bean id="sessionFactoryEditSolution" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="data1"/> <property name="mappingResources"> <list> <value>/master.hibernate.cfg.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> </props> </property> </bean>
