  • Maven: trying to get my submodule's poms to NOT inherit a plugin in the parent

    - by jobrahms
    My project has a parent pom and several submodule poms. I've put a plugin in the parent that is responsible for building our installer distributables (using install4j). It doesn't make sense to have this plugin run on the submodules, so I've put false in the plugin's config, as seen below. The problem is, when I run mvn clean install install4j:compile it cleans, compiles, and runs the install4j plugin on the parent, but then it tries to run it on the child modules and crashes. Here's the plugin config <plugin> <groupId>com.google.code.maven-install4j</groupId> <artifactId>maven-install4j-plugin</artifactId> <version>0.1.1</version> <inherited>false</inherited> <configuration> <executable>${devenv.install4jc}</executable> <configFile>${basedir}/newinstaller/ehd-demo.install4j</configFile> <releaseId>${project.version}</releaseId> <attach>false</attach> <skipOnMissingExecutable>true</skipOnMissingExecutable> </configuration> </plugin> Am I misunderstanding the purpose of inherited=false? What is the correct way to get this to work? I'm using maven 2.2.0.

  • How to implement message queuing and handling in AWS with NServiceBus

    - by Pete Lunenfeld
    I am creating a new ASP MVC order application in the Amazon (AWS) cloud with the persistence layer at my local datacenter. I will be using the CQRS pattern. The goal of the project is high availability using Queue(s) to store and forward writes (commands/events) that can be picked up and handled asynchronously at my local datacenter. Then, ff the WAN or my local datacenter fails, my cloud MVC app can still take orders and just queue them up until processing can resume. My first thought was to use AWS SQS for the queuing and create my own queue consumer/dispatcher/handler in my own c# application to process the incoming messages/events. MVC (@ Amazon) -- Event/POCO -- SQS -- QueueReader (@ my datacenter) -- DB Then I found NServiceBus. NSB seems to handle lots of details very nicely: message handling, retries, error handling, etc. I hate to reinvent the wheel, and NServiceBus seems like a full featured and mature product that would be perfect for me. But on further research, it does NOT look like NServiceBus is really meant to be used over the WAN in physically separated environments (Cloud to my Datacenter). Google and SO don't really paint a good picture of using NServiceBus across the WAN like I need. How can I use NServiceBus across the WAN? Or is there a better solution to handle queuing and message handling between Amazon an my local datacenter?

  • Paging not working in my wordpress installation

    - by Bootcamp
    I recently started a blog site and wanted to give it a magazine look. I used Wordpress for my blog and used the Arthemia theme with it. I also changed the permalink structure to point to /%year%/%monthnum%/%day%/%postname%/ structure. Now the problem that i have is that the paging has stopped working on my home page. When i click on the next page link i get a 404 error. My /page/2 url does not show the next page. I check on google and found out that it was due to the redirection that is being performed due to the permalink change. The solution given was that i need to skip the url rewriting for the /page/* urls. This is the link to an article which said this http://www.yoursearchadvisor.com/blog/wordpress-next_posts_link-broken/ . I was not able to follow this article and solve my problem, as i could not find the permanent redirect manager under the settings section as said in this article. Can somebody please guide me how to solve this problem. I am using the latest Wordpress version and Arthemia theme with it. Thanks.

  • Pre-populate iPhone Safari SQLite DB

    - by Matt Rogish
    I'm working with a PhoneGap app that uses Safari local storage (SQlite DB) via Javascript: http://developer.apple.com/safari/library/documentation/iPhone/Conceptual/SafariJSDatabaseGuide/UsingtheJavascriptDatabase/UsingtheJavascriptDatabase.html On first load, the app creates the database, tables, and populates the data via a series of INSERT statements. If the user closes the app while this processing is happening, then my app database is left in an inconsistent state. What I prefer to do is deploy the SQLite DB as part of my iTunes App packaging so nothing must be populated at app cold start. However, I'm not sure if that is possible -- all of the google hits for this topic that I can find are referring to the core-data provided SQLite which is not what we're using... If it's not possible, could I wrap the entire thing in a transaction and keep re-trying it when the app is restarted? Failing that, I guess I can create a simple table with one boolean column "is_app_db_loaded?" and set it to true after I've processed all my inserts. But that's really gross... Ideas? Thanks!!

  • Reporting Services - can't group by a column called "LanguageId"

    - by marc_s
    Folks, I have a really odd behavior here: I have a SQL Server 2008 Reporting Services report which gets grouped and sorted dynamically. One of the column in my data set which I display is called LanguageId and I was trying to get a grouping going by this LanguageId field. I checked, double-checked and triple-checked the data being returned - it does contain my expected values for LanguageId and everything seems fine and dandy. It just never worked - I didn't get the expected groups, I got things like a specific node actually changing its display value from one ID to another when expanding its subitems, and other really whacky stuff. I discovered that grouping and sorting by LanguageCaption works just fine. It also started working fine after I renamed LanguageId to MyLanguageId. So where on earth is this documented that LanguageId appears to be a system variable / reserved word / keyword of some sort in SQL Server Reporting Services that must be avoided at all costs?? I can't seem to find anything on that topic - even Mr. Google and Mrs. Bing came up empty so far....

  • 'C++ object destroyed' in QComboBox descendant editor in delegate

    - by Max
    Hi, all! I have modified combobox to hold colors, using QtColorCombo (http://qt.nokia.com/products/appdev/add-on-products/catalog/4/Widgets/qtcolorcombobox) as howto for the 'more...' button implementation details. It works fine in C++ and in PyQt on linux, but I get 'underlying C++ object was destroyed' when use this control in PyQt on Windows. It seels like the error happens when: ... # in constructor: self.activated.connect(self._emitActivatedColor) ... def _emitActivatedColor(self, index): if self._colorDialogEnabled and index == self.colorCount(): print '!!!!!!!!! QtGui.QColorDialog.getColor()' c = QtGui.QColorDialog.getColor() # <----- :( delegate fires 'closeEditor' print '!!!!!!!!! ' + c.name() if c.isValid(): self._numUserColors += 1 #at the next line currentColor() tries to access C++ layer and fails self.addColor(c, self.currentColor().name()) self.setCurrentIndex(index) ... Maybe console output will help. I've overridden event() in editor and got: ... MouseButtonRelease FocusOut Leave Paint Enter Leave FocusIn !!!!!!!!! QtGui.QColorDialog.getColor() WindowBlocked Paint WindowDeactivate !!!!!!!!! 'CloseEditor' fires! Hide HideToParent FocusOut DeferredDelete !!!!!!!!! #6e6eff ... Can someone explain, why there is such a different behaviour in the different environments, and maybe give a workaround to fix this. Here is minimal example: http://docs.google.com/Doc?docid=0Aa0otNVdbWrrZDdxYnF3NV80Y20yam1nZHM&hl=en

  • What to use for version control with Visual Studio 2008 for inhouse projects?

    - by Boog
    We want to put a number of our in-house projects under version control. Our projects are C# .NET applications and assemblies. We originally decided to go Microsoft all the way (as is the norm around here), and tried installing Visual Studio Team Foundation Server. To say the least, it was way more trouble of trying to get a successful install than it's worth, and I'm afraid we don't have a entire server to dedicate to TFS itself, as the installer seems to insist. We also considered a generic solution like Subversion or CVS, or possibly some kind of free online hosting that doesn't make our source publicly available under some license like Google Code appears to. Does anyone have any suggestions for us that would best fit our in-house MS environment? We'd also get some benefit out of some kind of project management tools if they were nicely integrated in to the solution, but this would only be a perk. I should also mention that we haven't entirely ruled out TFS, but it's looking like a pain, so anything you guys have to say for or against it would be helpful.

  • Where to store site settings: DB? XML? CONFIG? CLASS FILES?

    - by Emin
    I am re-building a news portal of which already have a large number of visits every day. One of the major concerns when re-building this site was to maximize performance and speed. Having said this, we have done many things from caching, to all sort of other measures to ensure speed. Now towards the end of the project, I am having a dilemma of where to store my site settings that would least affect performance. The site settings will include things such as: Domain, DefaultImgPath, Google Analytics code, default emails of editors as well as more dynamic design/display feature settings such as the background color of specific DIVs and default color for links etc.. As far as I know, I have 4 choices in storing all these info. Database: Storing general settings in the DB and caching them may be a solution however, I want to limit the access to the database for only necessary and essential functions of the project which generally are insert/update/delete news items, author articles etc.. XML: I can store these settings in an XML file but I have not done this sort of thing before so I don't know what kind of problems -if any- I might face in the future. CONFIG: I can also store these settings in web.config CLASS FILE: I can hard code all these settings in a SiteSettings class, but since the site admin himself will be able to edit these settings, It may not be the best solution. Currently, I am more close to choosing web.config but letting people fiddle with it too often is something I do not want. E.g. if somehow, I miss out a validation for something and it breaks the web.config, the whole site will go down. My concern basically is that, I cannot forsee any possible consequences of using any of the methods above (or is there any other?), I was hoping to get this question over to more experienced people out here who hopefully help make my decision.

  • How to change the css class="current" when using page jumping (single page website)?

    - by Bryan
    Morning, I must be asking google all the wrong questions, because I can't find anything similar. I have a standard navigation list, but I'm using page jumping because I wanted a single web page. <ul> <li><a href="#livestream">Livestream</a></li> <li><a href="#media">Media</a></li> <li><a href="#crew">Crew</a></li> <li><a href="#services">Services</a></li> <li><a href="#contact">Contact</a></li> </ul> But I can't for the life of me figure out how to make the class="current" when using page jumping. I've tried this bit of jquery because it appears to be what I'm looking for, but it did nothing. I don't think it'll work for #links. Any ideas?

  • memcmp,strcmp,strncmp in C

    - by el10780
    I wrote this small piece of code in C to test memcmp() strncmp() strcmp() functions in C. Here is the code that I wrote: #include <stdio.h> #include <stdlib.h> #include <string.h> int main(int argc, char** argv) { char *word1="apple",*word2="atoms"; if (strncmp(word1,word2,5)==0) printf("strncmp result.\n"); if (memcmp(word1,word2,5)==0) printf("memcmp result.\n"); if (strcmp(word1,word2)==0) printf("strcmp result.\n"); } Can somebody explain me the differences because I am confused with these three functions?My main problem is that I have a file in which I tokenize its line of it,the problem is that when I tokenize the word "atoms" in the file I have to stop the process of tokenizing.I first tried strcmp() but unfortunately when it reached to the point where the word "atoms" were placed in the file it didn't stop and it continued,but when I used either the memcmp() or the strncmp() it stopped and I was happy.But then I thought,what if there will be a case in which there is one string in which the first 5 letters are a,t,o,m,s and these are being followed by other letters.Unfortunately,my thoughts were right as I tested it using the above code by initializing word1 to "atomsaaaaa" and word2 to atoms and memcmp() and strncmp() in the if statements returned 0.On the other hand strcmp() it didn't.It seems that I must use strcmp(). I have done google searches but I got more confused as I have seen sites and other forums to define these three differently.If it is possible for someone to give me correct explanations/definitions so I can use them correctly in my source code,I would be really grateful.

  • SOAP web services in haskell?

    - by Dave
    I have to write a bunch of small web services. They must be defined by a WSDL and work via SOAP-RPC, in order to work with an existing workflow engine and service registry framework. I can, however, serve them on a service stack/platform of my choice. I'm presently writing them in Java, and it's not too bad. But I'm thinking my life might be easier if I was able to write these services in Haskell. Searching on Google, it looks like, once upon a time, someone else had the same idea and started a project called "HAIFA". However, it looks like HAIFA hasn't been maintained for some years, and I couldn't find any other frameworks supporting serving up services written in Haskell as SOAP web services. Does anyone know of any other frameworks that will allow me to easily write SOAP-based web services using Haskell? If not, has anyone done this manually (i.e., use XML libraries from hackage to process the incoming soap-rpc requests, and create soap-rpc compliant replies)? Was it difficult to do? Any gotchas? Was it worth the effort? Thanks in advance!

  • Weird onclick behavior of images on home screen widget

    - by kknight
    I wrote a home screen widget with one image on it. When the image is clicked, browser will be opened for a url link. Generally, it is working. But a weird thing is that, when I click background, then click the picture, the browser will not be open. Until I click the second time on the picture, the browser opens. The steps to reproduce is below: Click on the home screen widget background. Click on the image on the home screen. The browser is not opened. Click on the image again. The browser is opened. If I didn't click on the background, the image will react to click very well, i.e. browser will be open when the image is clicked the first time. The widget XML file is as below: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget" android:layout_width="320dip" android:layout_height="200dip" android:background="@drawable/prt_base" > <ImageView android:id="@+id/picture1" android:layout_width="134dip" android:layout_height="102dip" android:layout_marginLeft="62dip" android:layout_marginTop="6dip" android:scaleType="center" android:src="@drawable/picture1" /> </RelativeLayout> The code to set OnClick on the picture1 ImageView is as below: defineIntent = new Intent(Intent.ACTION_VIEW, Uri .parse("http://www.google.com")); pendingIntent = PendingIntent .getActivity(context, 0 /* no requestCode */, defineIntent, 0 /* no flags */); updateViews.setOnClickPendingIntent( picId, pendingIntent); Anyone knows what's wrong? Thanks.

  • Client-server synchronization pattern / algorithm?

    - by tm_lv
    I have a feeling that there must be client-server synchronization patterns out there. But i totally failed to google up one. Situation is quite simple - server is the central node, that multiple clients connect to and manipulate same data. Data can be split in atoms, in case of conflict, whatever is on server, has priority (to avoid getting user into conflict solving). Partial synchronization is preferred due to potentially large amounts of data. Are there any patterns / good practices for such situation, or if you don't know of any - what would be your approach? Below is how i now think to solve it: Parallel to data, a modification journal will be held, having all transactions timestamped. When client connects, it receives all changes since last check, in consolidated form (server goes through lists and removes additions that are followed by deletions, merges updates for each atom, etc.). Et voila, we are up to date. Alternative would be keeping modification date for each record, and instead of performing data deletes, just mark them as deleted. Any thoughts?

  • ScriptManager duplicates javascript

    - by Andreas
    Hi! I have a usercontrol that can be used in for example a gridview itemtemplate, this means that the control might or might not be on the page at page load. In the case where the control is inside an itemtemplate i will popupate the gridview via asyncronous postbacks (via updatepanels). The control itselfs registrers scriptblocks since it is depending on javascripts. First i used Page.ClientScript.RegistrerClientScriptBlock But this doesn't work on asyncronous postbacks (updatepanels) so i then tried the same using ScriptManager which allows me to registrer scripts on the page after async postbacks. great!. ScriptManager.RegisterClientScriptBlock However, ScriptManager (what i know of) does not have the functionallity to see if a script already is on the page, so i will for every postback generate duplicates of the script blocks, this is ofcourse unwanted behaviour. I did a run at Google and found that i can call the Dispose() method of the PageRequestManager can be used, this does work since it clears the scripts and then adding them again (this also solves my issue with removing unused script blocks from removed controls). Sys.WebForms.PageRequestManager.getInstance().Dispose() However, ofcourse there is a downside since im posting here :). The Dispose() method disposes the instance on the master page as well which leads to scripts running there will stop to function after an async postback (updateprogress for example). So, is there a way to check if a script already exists on the page using ScriptManager or any other tools, that will prevent me of inserting duplicate scripts? Also, is there a way to remove certain script blocks (when i am removing an item in itemtemplate for example). Big thanks in advance.

  • How to resolve the only ImagePicker control view in landscap mode and whole application in portrait mode?

    - by Wolvorin
    I have tried almost all the answers during last two days provided by Google and SO but no luck :( What I want is my whole application is in portrait mode only. And it working fine in ios 6+. The only support required at now. But the problem is I need to launch UIImagePickerViewController with image source type camera in only landscap mode. What I tried till now is : (1) I try to create one category for UIImagePickerController for orientation. -(BOOL)shouldAutorotate { return NO; } -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskLandscape; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return UIInterfaceOrientationLandscapeLeft; } Like this. But the camera view is not proper aligned. It just follows the orientation of device with some +/- 90 angle but not what I required. Even the button of the camera shown by camera view as camera control is also follows the camera view, ie. the view is rotated to 90 anti clock vise and stays to that way. Is there any way to use the camera with proper alignment? or have to use other framework to work with it? Please help me. I stuck with it for last two days.

  • SQL Server 2005 - Enabling both Named Pipes & TCP/IP protocols?

    - by Clinemi
    We have a SQL Server 2005 database, and currently all our users are connecting to the database via the TCP/IP protocol. The SQL Server Configuration Manager allows you to "enable" both Named Pipes, and TCP/IP connections at the same time. Is this a good idea? My question is not whether we should use named pipes instead of TCP/IP, but are there problems associated with enabling both? One of our client's IT guys, says that enabling database communication with both protocols will limit the bandwidth that either protocol can use - to like 50% of the total. I would think that the bandwidth that TCP/IP could use would be directly tied (inversely) to the amount of traffic that Named Pipes (or any of the other types of traffic) were occupying on the network at that moment. However, this IT person is indicating that the fact that we have enabled two protocols on the server, artificially limits the bandwidth that TCP/IP can use. Is this correct? I did Google searches but could not come up with an answer to this question. Any help would be appreciated.

  • cancelPreviousPerformRequestWithTarget is not canceling my previously delayed thread started with pe

    - by jmurphy
    Hello, I've launched a delayed thread using performSelector but the user still has the ability to hit the back button on the current view causing dealloc to be called. When this happens my thread still seems to be called which causes my app to crash because the properties that thread is trying to write to have been released. To solve this I am trying to call cancelPreviousPerformRequestsWithTarget to cancel the previous request but it doesn't seem to be working. Below are some code snippets. - (void) viewDidLoad { [self performSelector:@selector(myStopUpdatingLocation) withObject:nil afterDelay:6]; } (void)viewWillDisappear:(BOOL)animated { [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(myStopUpdatingLocation) object:nil]; } Am I doing something incorrect here? The method myStopUpdatingLocation is defined in the same class that I'm calling the perform requests. A little more background. The function that I'm trying to implement is to find a users location, search google for some locations around that location and display several annotations on the map. On viewDidLoad I start updating the location with CLLocationManager. I've build in a timeout after 6 seconds if I don't get my desired accuracy within the timeout and I'm using a performSelector to do this. What can happen is the user clicks the back button in the view and this thread will still execute even though all my properties have been released causing a crash. Thanks in advance! James

  • Return latitude/longitude based on entered address

    - by Don
    I'm building a php based application for a client to enter in addresses for their customers' buildings. They'd like the ability to view the location on a map (either as individuals or grouped in a city search). What I'm trying to accomplish is a lookup once the address is entered into a form that populates the database, so after they enter in the addresss, city, state, zip (these are all US locations) they could click a "get lat/long info" link/button that would check to make sure the data is complete, then would lookup the address and return the latitude/longitude into the appropriate form fields. Then the form could be submitted to store the info, and I could later just pull the lat/long when plotting on a map. 1) Does this make sense, or would I be better off just doing the lookup when it's time to plot it? 2) Does anyone have any pointers to solve this problem? I've seen some of the Google/Yahoo API's but it looks like this is more based on the plotting a point part. I may be able to modify it to suit my needs, but I'm just trying to cut some research time posting here with the hopes one of you may have a more direct route. I'll RTFM if I have to... Thanks, D.

  • algorithm to generate maximum number of character 'A' using keystrokes 'A', CTRL + 'A', CTRL + 'C' and CTRL + 'V'

    - by munda
    This is an interview question from google. I am not able to solve it by myself. Can somebody throw some light? The question goes like this. Write a program to print the sequence of keystrokes such that it generates the maximum number of character 'A's. You are allowed to use only 4 keys: 'A', CTRL + 'A', CTRL + 'C' and CTRL + 'V'. Only N keystrokes are allowed. All CTRL+ characters are considered as one keystroke, so CTRL+A is one keystroke. e.g.: A, ctrl+A, ctrl+C, ctrl+V generates two As in 4 keystrokes. Edit: CTRL + A is Select All CTRL + C is copy CTRL + V is paste I did some mathematics. For any N, using x numbers of A's , one CTRL+A, one CTRL+C and y CTRL+V, we can generate max ((N-1)/2)^2 numbers of A's. But for some N M, it is better to use as many ^A, ^C and ^V as it doubles the number of As. Edit 2: ^A, ^V and ^C will not overwrite on the existing selection but it will append the copied selection to selected one.

  • Calling Python app/script from C#

    - by Maxim Z.
    I'm building an ASP.NET MVC (C#) site where I want to implement STV (Single Transferable Vote) voting. I've used OpenSTV for voting scenarios before, with great success, but I've never used it programmatically. The OpenSTV Google Code project offers a Python script that allows usage of OpenSTV from other applications: import sys sys.path.append("path to openstv package") from openstv.ballots import Ballots from openstv.ReportPlugins.TextReport import TextReport from openstv.plugins import getMethodPlugins (ballotFname, method, reportFname) = sys.argv[1:] methods = getMethodPlugins("byName") f = open(reportFname, "w") try: b = Ballots() b.loadUnknown(ballotFname) except Exception, msg: print >> f, ("Unable to read ballots from %s" % ballotFname) print >> f, msg sys.exit(-1) try: e = methods[method](b) e.runElection() except Exception, msg: print >> f, ("Unable to count votes using %s" % method) print >> f, msg sys.exit(-1) try: r = TextReport(e, outputFile=f) r.generateReport(); except Exception, msg: print >> f, "Unable to write report" print >> f, msg sys.exit(-1) f.close() Is there a way for me to make such a Python call from my C# ASP.NET MVC site? If so, how? Thanks in advance!

If i made some mistakes when i publish this question forgive me and also forgive me for my bad english, thanks.

  • AppFabric caching's local cache isnt working for us... What are we doing wrong?

    - by Olly
    We are using appfabric as the 2ndlevel cache for an NHibernate asp.net application comprising a customer facing website and an admin website. They are both connected to the same cache so when admin updates something, the customer facing site is updated. It seems to be working OK - we have a CacheCLuster on a seperate server and all is well but we want to enable localcache to get better performance, however, it dosnt seem to be working. We have enabled it like this... bool UseLocalCache = int LocalCacheObjectCount = int.MaxValue; TimeSpan LocalCacheDefaultTimeout = TimeSpan.FromMinutes(3); DataCacheLocalCacheInvalidationPolicy LocalCacheInvalidationPolicy = DataCacheLocalCacheInvalidationPolicy.TimeoutBased; if (UseLocalCache) { configuration.LocalCacheProperties = new DataCacheLocalCacheProperties( LocalCacheObjectCount, LocalCacheDefaultTimeout, LocalCacheInvalidationPolicy ); // configuration.NotificationProperties = new DataCacheNotificationProperties(500, TimeSpan.FromSeconds(300)); } Initially we tried using a timeout invalidation policy (3mins) and our app felt like it was running faster. HOWEVER, we noticed that if we changed something in the admin site, it was immediatley updated in the live site. As we are using timeouts not notifications, this demonstrates that the local cache isnt being queried (or is, but is always missing). The cache.GetType().Name returns "LocalCache" - so the factory has made a local cache. Running "Get-Cache-Statistics MyCache" in PS on my dev environment (asp.net app running local from vs2008, cache cluster running on a seperate w2k8 machine) show a handful of Request Counts. However, on the Production environment, the Request Count increases dramaticaly. We tried following the method here to se the cache cliebt-server traffic... http://blogs.msdn.com/b/appfabriccat/archive/2010/09/20/appfabric-cache-peeking-into-client-amp-server-wcf-communication.aspx but the log file had nothing but the initial header in it - i.e no loggin either. I cant find anything in SO or Google. Have we done something wrong? Have we got a screwy install of AppFabric - we installed it via WebPlatform Installer - I think? (note: the IIS box running ASp.net isnt in yhe cluster - it is just the client). Any insights greatfully received!

  • Give More Prominence To DIV or <P> That Is After Floating DIV

    - by Aahan Krish
    Consider this HTML: <div id="entry-content"> <div id="my-300px-ad">AD CODE HERE</div> <p><img src="file.jpg" alt="file" /></p> <p>SOME TEXT</p> <p>SOME MORE TEXT</p> </div> Now, consider that the div#my-300px-ad is floating right. Would it be possible for me to have the image in the next paragraph show up before the ad so that the TEXT in its following paragraphs can wrap around the ad? For example, like this: Why so...? The thing is, due to various reasons (including Google) I want to avoid placing an ad in BETWEEN the post's content. CSS only I am sure that something like this would be possible with some JavaScript code. But I am looking for a CSS-based solution only. (Cross-browser compatibility, = IE8) Please note that ONLY the CSS of div#my-300px-ad can be changed. Nothing else should be touched as this is not a static HTML page, besides they are articles. PS: It was hard to frame a one-line question for this. Please feel free to edit the question's title if it can be made more clear.
