• Cannot get admob working: configChanges error

  - by Jack Commonw

  I know there are some topics about it, but the reason I start this one is I appear not to be able to solve it with solutions given. I want to add admob to my project. I downloaded GoogleAdMobAdsSdk-6.2.1 and added it to my project. When I startup it says You must have AdActivity declared in AndroidManifest with configChanges. So solution found, set it to: android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" and <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="15" /> Clean it, try again. But now I get an error saying following although my targetSdkVersion is set to be min 12, I really don't know why I am still getting this error: String types not allowed (at 'configChanges' with value 'keyboard|keyboardHidden|orientation| screenLayout|uiMode|screenSize|smallestScreenSize') Any ideas on this? There might be another setting wrong which I looked over?

• Posting a form with anchor link at the end?

  - by Marcus

  I have a form for comments like the one below but after the form is posted I wish to navigate to http://www.myurl.com/mypage#commentform but I don't know how to do this. Instead of changing my form maybe there is a way to return a View with my model and add #commentform to my url? <div id="commentform"> <h2>Leave a comment</h2> <% using (Html.BeginForm("Comment","Post", FormMethod.Post)) %> <% { %> <div> <%=Html.EditorFor(post => post.Comment) %> <div class="editor-button"> <input type="submit" value="Comment" /> </div> </div> <% } %> </div>

• compiler warning on (ambiguous) method resolution with named parameters

  - by FireSnake

  One question regarding whether the following code should yield a compiler warning or not (it doesn't). It declares two methods of the same name/return type, one has an additional named/optional parameter with default value. NOTE: technically the resolution isn't ambiguous, because the rules clearly state that the first method will get called. See here, Overload resolution, third bullet point. This behavior is also intuitive to me, no question. public void Foo(int arg) { ... } public void Foo(int arg, bool bar = true) { ...} Foo(42); // shouldn't this give a compiler warning? I think a compiler warning would be kind of intuitive here. Though the code technically is clean (whether it is a sound design is a different question:)).

• ASP.NET MVC Session across subdomains

  - by nccsbim071

  Hi, In my website i have implemented custom session values. In which, on log on i set the session value to some object. This object is used to extract user specific data from db. now the problem is If user logs in with : test1.somesite.com and logs off and again logs in with: test2.somesite.com that user is still receiving the data from object specific to test1.somesite.com. the point is whichever site user frist logs in with the second time if he logs in with anathor subdomain he is always getting the data from previous sub domain login. on log out from specific domain i cleared all the sessions(tried everything): by putting HttpContext.session["UserDetail"] = null;, HttpContext.Session.Abandon() and also HttpContext.Session.Clear(); but nothing seems to work any help please

• Working with the Grails g:timeZoneSelect tag?

  - by tinny

  I am wanting to use the g:timeZoneSelect tag within my application, problem is im finding the resulting html select to be quite overwhelming. Over 600 options are being displayed, IMHO this is to much to display to the user. Maybe someone could point me to an example of a much more manageable list of timezones? Maybe you have seen a site that does timezone selection well? Im sure over 600 option is "technically" correct, but this will just look like noise to the user. The display value of the timezone is to long. E.g. "CST, Central Standard Time (South Australia/New South Wales) 9.5:30.0" Just "CST, Central Standard Time" or "Australia/Broken_Hill" would be better Is there a way to address these issues via tag attributes of some sort (cant find any in the docs) or config that I am unaware of? Or, is my best bet to wrap an html select within a custom tag lib and "roll my own" solution (Id prefer not to). Thanks

• How do I set the user's locale on a JSP

  - by ebynum

  I have a .jsp page that the user loads directly. The request it with a URL like the following: http://www.example.com/myfile.jsp?country=CA&language=fr In the JSP, I pull the URL GET parameters and attempt to set the locale using them as follows: <% String myLanguage = request.getParameter("language"); String myCountry = request.getParameter("country"); Locale myLocale = new Locale(myLanguage, myCountry); pageContext.setAttribute("myLocale", myLocale, PageContext.PAGE_SCOPE); %> <fmt:setLocale value="${myLocale}" scope="page" /> There are several places in the JSP that then display a message pulled from a localized resource bundle using <bean:message bundle="ts" key="..." /> from Struts. On the first request for this page (after changing the language in the URL), it is returned in US English (the default Locale), and then subsequent refreshes will return the properly localized content.

• How do you solve this Haskell problem using a fold map and take?

  - by Linda Cohen

  Define a function replicate which given a list of numbers returns a list with each number duplicated its value. Use a fold, map, and take .. replicate [5,1,3,2,8,1,2] output: [5,5,5,5,5,1,3,3,3,2,2,8,8,8,8,8,8,8,8,1,2,2] I've figure this out using List comprehension and recursion: replicate2 [] = [] replicate2 (n:nn) = take n(repeat n) ++ replicate2 nn but how would you use fold and map to do this? so far I have: replicate n = map (foldl1 (take n(repeat n)) n) n which is obviously wrong, but I think I am close.. so any help would be nice, THANKS!

• What's the best practice to "look up" Java Enums?

  - by Marcus

  We have a REST API where clients can supply parameters representing values defined on the server in Java Enums. So we can provide a descriptive error, we add this lookup method to each Enum. Seems like we're just copying code (bad). Is there a better practice? public enum MyEnum { A, B, C, D; public static MyEnum lookup(String id) { try { return MyEnum.valueOf(id); } catch (IllegalArgumentException e) { throw new RuntimeException("Invalid value for my enum blah blah: " + id); } } } Update: The default error message provided by valueOf(..) would be No enum const class a.b.c.MyEnum.BadValue. I would like to provide a more descriptive error from the API.

• Best practice for string substition with gettext using Python

  - by Malcolm

  Looking for best practice advice on what string substitution technique to use when using gettext(). Or do all techniques apply equally? I can think of at least 3 string techniques: Classic "%" based formatting: "My name is %(name)s" % locals() .format() based formatting: "My name is {name}".format( locals() ) string.Template.safe_substitute() import string template = string.Template( "My name is ${name}" ) template.safe_substitute( locals() ) The advantage of the string.Template technique is that a translated string with with an incorrectly spelled variable reference can still yield a usable string value while the other techniques unconditionally raise an exception. The downside of the string.Template technique appears to be the inability for one to customize how a variable is formatted (padding, justification, width, etc).

• Determine if Alpha Channel is Used in an Image

  - by Otaku

  As I'm bringing in images into my program, I want to determine if: they have an alpha-channel if that alpha-channel is used #1 is simple enough with using Image.IsAlphaPixelFormat. For #2 though, other than looping through every single pixel, is there a simple way I can determine if at least one of the pixels has an alpha channel that is used (i.e. set to some other value than 255)? All I need back is a boolean and then I'll make determination as to whether to save it out to 32-bit or 24-bit.

• What is the best way to convert a hexidecimal string to a byte array (.NET)?

  - by Robert Wagner

  I have a hexidecimal string that I need to convert to a byte array. The best way (ie efficient and least code) is: string hexstr = "683A2134"; byte[] bytes = new byte[hexstr.Length/2]; for(int x = 0; x < bytes.Length; x++) { bytes[x] = Convert.ToByte(hexstr.Substring(x * 2, 2), 16); } In the case where I have a 32bit value I can do the following: string hexstr = "683A2134"; byte[] bytes = BitConverter.GetBytes(Convert.ToInt32(hexstr, 16)); However what about in the general case? Is there a better built in function, or a clearer (doesn't have to be faster, but still performant) way of doing this? I would prefer a built in function as there seems to be one for everything (well common things) except this particular conversion.

• possible bug in geom_ribbon

  - by tomw

  i was hoping to plot two time series and shade the space between the series according to which series is larger at that time. here are the two series-- first in a data frame with an indicator for whichever series is larger at that time d1 <- read.csv("https://dl.dropbox.com/s/0txm3f70msd3nm6/ribbon%20data.csv?dl=1") And this is the melted series. d2 <- read.csv("https://dl.dropbox.com/s/6ohwmtkhpsutpig/melted%20ribbon%20data.csv?dl=1") which I plot... ggplot() + geom_line(data = d2, aes(x = time, y = value, group = variable, color = variable)) + geom_hline(yintercept = 0, linetype = 2) + geom_ribbon(data = d1[d1$big == "B",], aes(x = time, ymin = csa, ymax = csb), alpha = .25, fill = "#9999CC") + geom_ribbon(data = d1[d1$big == "A",], aes(x = time, ymin = csb, ymax = csa), alpha = .25, fill = "#CC6666") + scale_color_manual(values = c("#CC6666" , "#9999CC")) which results in... why is there a superfluous blue band in the middle of the plot?

• Addslashes, mysql_real_escape always adding two slashes?

  - by Zach

  I'm having an issue with inserting JSON into a database, my intention is to take the variables, json_encode them, remove slashes (from magic_quotes), and then addslashes back in to escape the quotes in {"key":"value"} Unfortunately, strip_slashes on the encoded string isn't doing anything, and outputs this {"content":"<p>This string has it\'s downsides</p>","date":1271352514} I have then tried addslashes, and mysql_real_escape_string, both output "{\\"content\\":\\"<p>This string has it\\\'s downsides</p>\\",\\"date\\":1271352514}" I can't work out why it's adding in two slashes? And I'm tearing my hair out over this, everytime I try to stripslashes it leaves one in, and adding slashes adds two. Any help would be hugely appreciated!

• Nhibernate ValueType Collection as delimited string in DB

  - by JWendel

  Hi I have a legacy db that I am mapping with Nhibernate. And in several locations a list och strigs or domain objects are mapped as a delimited string in the database. Either 'string|string|string' in the value type cases and like 'domainID|domainID|domainID' in the references type cases. I know I can create a dummy property on the class and map to that fields but I would like to do it in a more clean way, like when mapping Enums as their string representation with the EnumStringType class. Is a IUserType the way to go here? Thanks in advance /Johan

• Can I mix compile time string comparison with MPL templates?

  - by Negative Zero

  I got this compile time string comparison from another thread using constexpr and C++11 (http://stackoverflow.com/questions/5721813/compile-time-assert-for-string-equality). It works with constant strings like "OK" constexpr bool isequal(char const *one, char const *two) { return (*one && *two) ? (*one == *two && isequal(one + 1, two + 1)) : (!*one && !*two); } I am trying to use it in the following context: static_assert(isequal(boost::mpl::c_str<boost::mpl::string<'ak'>>::value, "ak"), "should not fail"); But it gives me an compilation error of static_assert expression is not an constant integral expression. Can I do this?

• java.util.Date.toString() is printing out wrong format

  - by pacoverflow

  The following code prints out "vmtDataOrig.creationdate=2012-11-03" VmtData vmtDataOrig = VmtDataDao.getInstance().loadVmt(1); System.out.println("vmtDataOrig.creationdate=" + vmtDataOrig.getCreationDate().toString()); Here is the definition of the creationDate field in the VmtData class: private Date creationDate = null; Here is the hibernate mapping of the creationDate field to the database table column: <property name="creationDate" column="CREATIONDATE" type="date"/> The CREATIONDATE column in the MySQL database table is of type "date", and for the record retrieved it has the value "2012-11-03". The Javadoc for the java.util.Date.toString() method says it is supposed to print the Date object in the form "dow mon dd hh:mm:ss zzz yyyy". Anyone know why it is printing it out in the form "yyyy-MM-dd"?

• Using javascript on an HTML table?

  - by Michael McKay

  Hi, few questions, just wondering if anyone can help? I have a table with 1 long row (1000 pixels) and one single column, how do i go about creating a method whereby when the mouse cursor is on the leftmost side of the cell, a variable, lets say X is set to 0, the further right the mouse cursor moves in the cell, the value of X increases. I know that sounds like a strange question but im working on a project where this type of functionality is desired. Is there a javascript method to create this feature? Thanks for any help.

• Does the `Expires` HTTP header needs to be consistent across multiple cold-cache requests?

  - by chakrit

  I'm implementing a custom web server of a kind. And am looking into adding an Expires header support. However, I'm a little unsure of how exactly to implement it. If multiple cold-cache requests are being made to the same unchanged resource on the server and the server returned different Expires header (say it uses relative time to calculate the exact value of the Expires date e.g. +6 hours from the request time), does that invalidate the cache on all the proxy servers in-between as well? Or is it impossible to happen (per the spec)? Does the Expires HTTP header needs to be consistent across multiple cold-cache requests?

• Are memcached entries saved by the Danga client compatible with the Spy client?

  - by jigjig

  After saving a String value into memcached using the Danga client, I attempted to get the entry using the Spy client. The two String values are not the same. The Danga client retrieves a string with an additional empty char prepended to the string, therefore violating the equality condition. Danga: t,e,s,t,s,t,r,i,n,g Spy: ,t,e,s,t,s,t,r,i,n,g I also attempted to save a serialized Map using the Danga client and get the Map using the Spy client. The Spy client is able to only get a String form of the Map. The string contains binary values, as below: sr

• Ruby: Locate class definition at run time?

  - by Thor Thurn

  I'm having an odd probably with rails right now... a class is being defined somewhere, and I can't find it. Grepping for "class ClassName" hasn't managed to locate it, but it's definitely there when I load up the rails console. It's just a vanilla class inheriting from Object with nothing else defined... quite boring. So, what I'd like is a way to figure out where this class constant was originally defined from the rails console. Something to print out the value of '__ FILE __' when this class was declared, in other words. I feel like some type of metaprogramming should make this possible.

• Strict pointer aliasing: any solution for a specific problem?

  - by doublep

  I have a problem caused by breaking strict pointer aliasing rule. I have a type T that comes from a template and some integral type Int of the same size (as with sizeof). My code essentially does the following: T x = some_other_t; if (*reinterpret_cast <Int*> (&x) == 0) ... Because T is some arbitary (other than the size restriction) type that could have a constructor, I cannot make a union of T and Int. (This is allowed only in C++0x only and isn't even supported by GCC yet). Is there any way I could rewrite the above pseudocode to preserve functionality and avoid breaking strict aliasing rule? Note that this is a template, I cannot control T or value of some_other_t; the assignment and subsequent comparison do happen inside the templated code. (For the record, the above code started breaking on GCC 4.5 if T contains any bit fields.)

• Managing important runtime business logic with regard to a codebase

  - by Daniel Beardsley

  I'm working on a project which will end up have a lot of application information stored in the form of records in a database. In this case, it's the configuration of data views: which grid columns to show/hide default filters to apply to each grid view column titles sorting subtotaling ... This information is a big part of the value of the application and is essential to it's function. The data will be altered by admins a fair amount, so it's not static and it wouldn't be appropriate to have to deploy a new version of the app every time the data changes. The question is, Where should this data be stored? It will definitely live in the database because that's how it's accessed, but I feel like it needs to also be kept with the version controlled codebase because it's an integral part of functioning of the application. Has anyone dealt with an issue like this before? What did you end up doing?
