• Android Graphics Memory Limits

  - by Gordon

  I am creating an android game using opengl and a cocos2d port (http://code.google.com/p/cocos2d-android-1). I am targeting a wide range of devices and want to ensure that it performs well. I only test on a nexus one and am hoping to get some input from people with experience on slower devices. Currently the game uses two 1024x1024 textures as well as two 256x256 textures. Is this within the limits of most devices? Anyone have any rule of thumb or experience with graphics memory limits in these cases? If gfx memory is exceeded does it page to normal memory?

• Do mini-filter functions need APCs enabled?

  - by botismarius

  Hello, Many Zw* functions that work with files (such as ZwCreateFile) need to be called at PASSIVE_LEVEL with APCs enabled: http://msdn.microsoft.com/en-us/library/ff566424%28VS.85%29.aspx. This is because, internally, I/O operations are asynchronously and the completion of an operation is delivered through an APC (correct me if I'm wrong). However, the documentation for similar functions from a mini-filter (such as FltCreateFile, FltReadFile, etc) does not specify that APCs should be enabled. Is it safe to call FltCreateFile/FltReadFile with APCs disabled? Thanks!

• Can I use Linq to project a new typed datarow?

  - by itchi

  I currently have a csv file that I'm parsing with an example from here: http://alexreg.wordpress.com/2009/05/03/strongly-typed-csv-reader-in-c/ I then want to loop the records and insert them using a typed dataset xsd to an Oracle database. It's not that difficult, something like: foreach (var csvItem in csvfile) { DataSet.MYTABLEDataTable DT = new DataSet.MYTABLEDataTable(); DataSet.MYTABLERow row = DT.NewMYTABLERow(); row.FIELD1 = csvItem.FIELD1; row.FIELD2 = csvItem.FIELD2; } I was wondering how I would do something with LINQ projection: var test = from csvItem in csvfile select new MYTABLERow { FIELD1 = csvItem.FIELD1, FIELD2 = csvItem.FIELD2 } But I don't think I can create datarows like this without the use of a rowbuilder, or maybe a better constructor for the datarow?

• Matching Line Boundaries in a Regular Expression (Pattern.MULTILINE/(?m)) is broken in Java?

  - by Mister M. Bean

  The example on http://www.exampledepot.com/egs/java.util.regex/Line.html gives false for me twice but should'nt! Why? CharSequence inputStr = "abc\ndef"; String patternStr = "abc$"; // Compile with multiline enabled Pattern pattern = Pattern.compile(patternStr, Pattern.MULTILINE); Matcher matcher = pattern.matcher(inputStr); boolean matchFound = matcher.find(); // true // Use an inline modifier to enable multiline mode matchFound = pattern.matches(".*abc$.*", "abc\r\ndef"); // false System.out.println(matchFound); // false matchFound = pattern.matches("(?m).*abc$.*", "abc\r\ndef"); // true System.out.println(matchFound);// false !!!!!

• Isolated storage

  - by Costa

  Hi I am not sure that I understand Isolated storage. I read the article http://msdn.microsoft.com/en-us/library/3ak841sy%28VS.80%29.aspx 1) Why I don't just use App data folder? 2) In the link above : "With isolated storage, data is always isolated by user and by assembly. Credentials such as the origin or the strong name of the assembly determine assembly identity. Data can also be isolated by application domain, using similar credentials." I can't think about a scenario that makes this future important. In general I don't understand the philosophy and the need of "isolated storage" which inspire MS to create such a thing. Thanks

• IE8 positions DIV overlay wrong way and keeps playing video when it's hidden.

  - by George

  Hi! Please take a look at: http://www.binarymark.com/Products/PasswordGenerator/default.aspx (the Overview tab, on the diagram). The issue is wjen you click on any of the diagram elements say "Character Groups" all browsers, except IE8 behave well - that is they display the overlay, start playing a video, and when the overlay is closed, the video stops playing an the div is hidden. IE8, on the other hand has two flaws: it positions the overlay way towards the bottom and too much to the right, and even more annoyingly - it keeps playing video in the background even when the overlay div is closed! I use flowplayer.org/tools/overlay/ for overlay. Can you help please? Thanks.

• How does the dispatch action call work in the Twitter sidebar

  - by phwd

  I would like to understand how the call for replies works as follows: <a href="http://twitter.com/replies" data="{"dispatch_action":"replies"}"> <span>@phwd</span> </a> This was taken from the homepage of Twitter. The section in particular being: data="{"dispatch_action":"replies"}" I believe (think), it is using Twitter's own twitter.js script and I do not want to interfere(or copy) with their code, I rather just want to know how the call works. My current setup is using Abraham's twitteroauth PHP library, jQuery and some Ajax to refresh the portion of the page needed using the following method : Use jQuery and PHP to build an Ajax-driven Web page [IBM link - I am a new user so I can only post one link] I apologize if this question is not formatted/worded well, it is my first time. Also I tried searching DocType and StackOverFlow. The Related Questions show me Struts but I am not sure it is that.

• Need help specifying a ending while condition

  - by johnthexiii

  I have written a Python script to download all of the xkcd comic images. The only problem is I can't tell it to stop when it gets to the last one... Here is what I have so far. import re, mechanize from urllib import urlretrieve from BeautifulSoup import BeautifulSoup as bs baseUrl = "http://xkcd.com/1/" #Specify the first comic page br = mechanize.Browser() #Create a browser response = br.open(baseUrl) #Create an initial response x = 1 #Assign an initial file name while (SomeCondition): soup = bs(response.get_data()) #Create an instance of bs that contains the response data img = soup.findAll('img')[1] #Get the online file path of the image localFile = "C:\\Comics\\xkcd\\" + str(x) + ".jpg" #Come up with a local file name urlretrieve(img["src"], localFile) #Download the image file response = br.follow_link(text = "Next >") #Store the response of the next button x += 1 #Increase x by 1 print "All xkcd comics downloaded" #Let the user know the images have been downloaded Initially what I had was something like while br.follow_link(text = "Next >") != br.follow_link(text = ">|"): but by doing this I actually send skip to the last page before the script has a chance to perform the intended purpose.

• How to align item to the very bottom within flexible box layout column?

  - by Christina Lacey

  So far I have the three columns laid out in a vertical box (can't post images yet so here's a link): http://imgur.com/4Y34c <div id="vbox"> <div id="blck1"></div> <div id="blck2"></div> <div id="blck3"><div id="yellow"></div><div id="blue"></div></div> </div> css #vbox{ display: box; box-orient: vertical; } #vbox > div { box-flex: 1; } The problem is that I don't know how to get the blue box to align to the bottom of the third column.. I tried all the alignment properties, i must be doing something wrong. Any ideas???

• DVCS - What's the downside of rewriting unpublished history?

  - by user1447278

  I was wondering what in particular is the downside of "losing history" in a development process. One famous example is of course git rebase -i / git merge --squash, but also what is described here: http://fourkitchens.com/blog/2009/04/20/alternatives-rebasing-bazaar under "I want to clean up my commit history prior to submitting my changes to the mainline." I can see that exporting patches and applying them to another branch would lose the "history" of the branch, but why would that branch and its commit history be useful after it has been merged? Can someone elaborate on why such techniques are considered "dirty"? Why does it matter in which order changes were originally committed in the first place as long as they can be applied to the main branch?

• php, extract data from a non-standard xml document

  - by Michael

  I have some kind xml content I need to extract the information and store it into database <xml file="136000000-136100000"> <Id>136000000</Id> <Name>Sem Serxy</Na me> <Email>[email protected]</Email> <DateRegistration>10/13/2010 1:49:30 AM</DateRegistration> </xml> <xml file="136000000-136100000"> <Id>136000001</Id> <Name>God Deckor</Name> <Email>[email protected]</Email> If I try simple xml load is not working as the document doesn't seem to be valid xml. I can use regex to extract the info with preg_match_all but I feel this is not the right way as the data is already well structured. Any other method ?

• Installing SharePoint 2010 on a dev machine with an external database

  - by Dan Revell

  I've been following Microsoft's guide for installing a dev environment on Windows 7: http://msdn.microsoft.com/en-us/library/ee554869.aspx In order for it to not run like a dog I've created a SQL Server 2008 instance on our database server specifically for this dev machine. The article does mention that you might be wanting to use an external database in regard to making sure the database cumulative update is installed. It doesn't make any other mention of configuring it to use a external database. I was hoping that the configuration wizard would then prompt about which database to use but annoyingly it just set-up the configuration database locally. How do I go about installing SharePoint on a dev environment with an external database, and will I need to reformat this machine and do it all again?

• C# Elegant way to handle checking for an item in a collection.

  - by JL

  I've posted a code sample below. Firstly let me explain termStore.Groups in the code below is a collection of Group Objects (The exact class is irrelevant). Checking for null : if (termStore.Groups[groupName] == null) seems like a logical (clean) approach, but if the Groups collection is empty then an exception is produced. using the termStore.Groups.Contains is not an option either because this expects a strong type i.e: .Contains(Group)... not .Contains(GroupName as string) Can someone recommend a clean / generic way I can check for if an item exists in collection . Thank you.... TermStore termStore = session.TermStores.Where(ts => ts.Name == termStoreName).FirstOrDefault(); if (termStore.Groups[groupName] == null) { termStore.CreateGroup(groupName); termStore.CommitAll(); } Update: The exact class Sharepoint Taxonomy Classes. http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.taxonomy.group.aspx

• Simple user control for conditionally rendering nested HTML

  - by Goyuix

  What I would like to do, is be able to pass two attributes to a user control, a ListName and a Permission, like so: <uc:check id="uc" List="Shared Documents" Permission="OpenItems" runat="server"> <!-- have some HTML content here that is rendered if the permission is true --> </uc:check> Then in the actual check user control, have something similar to: <%@ Control language="C#" ClassName="check" %> <% // determine permission magic placeholder if (DoesUserHavePermissions(perm)) { // render nested HTML content } else { // abort rendering as to not show nested HTML content } %> I have read the page on creating a templated control on MSDN, and while that would work - it really seems to be a bit overkill for what I am trying to do. Is there a control that already renders content based on a boolean expression or a simpler template example? http://msdn.microsoft.com/en-us/library/36574bf6.aspx

• How can I sqldump a huge database?

  - by meder

  SELECT count(*) from table gives me 3296869 rows. The table only contains 4 columns, storing dropped domains. I tried to dump the sql through: $backupFile = $dbname . date("Y-m-d-H-i-s") . '.gz'; $command = "mysqldump --opt -h $dbhost -u $dbuser -p $dbpass $dbname | gzip > $backupFile"; However, this just dumps an empty 20 KB gzipped file. My client is using shared hosting so the server specs and resource usage aren't top of the line. I'm not even given ssh access or access directly to the database so I have to make queries through PHP scripts I upload via FTP ( SFTP isn't an option, again ). Is there some way I can perhaps sequentially download portions of it, or pass an argument to mysqldump that will optimize it? I came across http://jeremy.zawodny.com/blog/archives/000690.html which mentions the -q flag and tried that but it didn't seem to do anything differently.

• jQuery .animate reveal contact form hidden in div with negative margin above header

  - by brhea

  Hi everyone, I've got my contact form hidden with a negative margin-top, so that when the visitor clicks "Contact" it reveals the div. <script type="text/javascript">$("#revealContact").click(function(){ $("#contact").animate({ marginTop: "+=620px" }, 1000); });</script> You can view it live here: http://www.brianrhea.com/index_contact.php -- click Contact link in top right My problem is that as soon as the form is submitted, it inherits the -620 margin and the success (or error) prompt is invisible. I'm running in to some other cross-compatibility issues as well with the margin spacing so I'm not even sure this is the best way to go about this. Obviously it'd be great if I could just begin with the div as display:hidden and then animate it to visible, but I haven't been able to do that. Any input is appreciated, either with advice on how to save the margin after form submission, or suggestion on better method to achieve this hide/reveal. Thanks, Brian

• Is there a better method for scrolling a page (with jQuery) in Safari for iPhone (scrollTop doesn't

  - by Keeron

  Hi there, I am working on an iPhone version of a website, and I am using jQuery .animate() with the scrollTop attribute to scroll to different sections of the page. Something like so: $('html,body').animate({ scrollTop: distance }, 300); On regular web browsers, the scrolling starts from the current window position to the desired position. On the iPhone, the window jumps back to the top of the document before scrolling to the desired position. This is apparently the intended action, but the pages just don't look good with all that movement. Alternatively, on Google.com for the iPhone, when the autosuggest is activated, there is a nice simple scroll to show the autosuggest options below the search box. That's what I'd like to do...

• WCF host address question

  - by Estelle

  when I setup the wcf service on a web server, I set the end point address as <endpoint address="http://www.mydomin.com/clientname/happy.svc" binding="basicHttpBinding" name="happysvcbasic" contract="happysvc.Ihappysvc"> </endpoint> but when type in above address on a browser, I get a different host name, which is the internal server name, such as, To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://internalservername.domain/clientname/happy.svc?wsdl I tried to add the host/baseaddress tag, but make no difference, what I missed? thanks for help.

• Ideas for using R to create a T-shirt design (for useR 2010) ?

  - by Tal Galili

  There is now a competition for creating a T-shirt design for useR2010. Someone proposed the idea to use R for creating the T-shirt image. Which leads me to my questions: What type of images do you think might be fitting for this? How would you suggest to use R to create the images ? Would anyone here want to have a go at it? (p.s: I understand this is not a pure "programming" question. Yet it involves R programming, the understanding of R aesthetics, and some caring for the R community. I also understand I am at the risk of annoying people here with this question, so in case that happens - I deeply apologies! My only justification is that I am acting in good faith and in the purpose of having nice things for R users to enjoy, while learning something in the process) Related thread I once opened: http://stackoverflow.com/questions/2162131/how-can-i-learn-to-create-beautiful-infographics-with-connection-to-my-r-knowled

• Breaking change October: Status waiting when create custom audience with add user data file?

  - by THACH LN

  In my system, I create a custom audience - data file - mobile advertiser ids with 10k user. After I created it, I refreshed API link to get information about the audience which I've just created: https://graph.facebook.com/act_xxx/customaudiences?fields=id,account_id,name,lookalike_spec,retention_days,subtype,approximate_count,rule,delivery_status,operation_status,data_source,permission_for_actions&limit=500&access_token=xxx. (After breaking change in October 2014, status field not return. So I see operation_status) I see that: "operation_status": { "code": 410, "description": "No file has been uploaded for this audience, or the previous upload has failed due to system error. Please try uploading the file again." } But after about 10s, I refresh again, and operation_status change to: "operation_status": { "code": 200, "description": "Normal" } My quetions is: how to check this audience's status is waiting ( uploading file) , like when I create on facebook not my our system. Thanks for all anwser.

• which MVC for coldfusion?

  - by mrjayviper

  newbie to MVC here. so please be gentle. I want to move one of our existing apps (currently located in http://www.companywebsitegoeshere.com/myapp1) to MVC. As can be seen in the URL, there are many apps running in the website which I intend to move at some stage. I don't have write access to the wwwroot (/var/www/html in my case) and the webserver is used by multiple developers across the company. I'm hoping I can have the MVC framework core files/folders + my app all located in in 1 subfolder. In the case of myapp1, all the filers and folders will be inside /var/www/html/myapp1 subfolder. Can you please point me to the right direction (links/guides/docs/videos/etc)? I've looked at several like cfwheels/mach-ii/fw1 but they seemed requires wwwroot access. Thanks! :)
