• How can I clear the appcache on the Google Chrome iPad app?

  - by Jannis

  I've written a little HTML5 based web app that I am trying to debug on the iPad using the Chrome for iPad app. I have added a cache.manifest file to my app which has some heavy caching in it of most static resources however since I am now wanting to debug the app I need a way to clear this cache. I know that on Chrome for Mac you can use: chrome://appcache-internals/ however this page does not exist in the iPad app of Chrome. The regular "Clear Browsing Data" does not empty the appcache —at least not in my case. Does anyone know how I can clear the appcache for the Chrome iPad app?

• Find window handle of a ribbon button

  - by ldx

  Hi, I'm trying to do some automation of windows applications. To do whatever I want to do, I need the window handles of some controls. Before, I would accomplish this with a combination EnumWindows, EnumChildWindows and GetWindowText. But now, some newer programs no longer have toolbar with buttons on it. Instead, they have a ribbon. This didn't seem like much of a problem to me at first, but now I notice that the buttons on the ribbon don't show up in EnumChildWindows! Or at least GetWindowText does not return the same text as the one seen on the screen. So to make a long story short: Can anybody tell me how I can programatically find the handle of a button on a ribbon? Thanks. Regards, ldx

• Reference table values in a war against magic numbers

  - by Alex N.

  This question bugged me for years now and can't seem to find good solution still. I working in PHP and Java but it sounds like this maybe language-agnostic :) Say we have a standard status reference table that holds status ids for some kind of entity. Further let's assume the table will have just 5 values, and will remain like this for a long time, maybe edited occasionally with addition of a new status. When you fetch a row and need to see what status it is you have 2 options(as I see it at least) - put it straight ID values(magic numbers that is) or use a named constant. Latter seem much cleaner, the question though is where those named constants should leave? In a model class? In a class that uses this particular constant? Somewhere else?

• Multiple python scripts sending messages to a single central script

  - by Ipsquiggle

  I have a number of scripts written in Python 2.6 that can be run arbitrarily. I would like to have a single central script that collects the output and displays it in a single log. Ideally it would satisfy these requirements: Every script sends its messages to the same "receiver" for display. If the receiver is not running when the first script tries to send a message, it is started. The receiver can also be launched and ended manually. (Though if ended, it will restart if another script tries to send a message.) The scripts can be run in any order, even simultaneously. Runs on Windows. Multiplatform is better, but at least it needs to work on Windows. I've come across some hints: os.pipe() multiprocess Occupying a port mutex From those pieces, I think I could cobble something together. Just wondering if there is an obviously 'right' way of doing this, or if I could learn from anyone's mistakes.

• What elegant method callback design should be used ?

  - by ereOn

  Hi, I'm surprised this question wasn't asked before on SO (well, at least I couldn't find it). Have you ever designed a method-callback pattern (something like a "pointer" to a class method) in C++ and, if so, how did you do it ? I know a method is just a regular function with some hidden this parameter to serve as a context and I have a pretty simple design in mind. However, since things are often more complex than they seem to, I wonder how our C++ gurus would implement this, preferably in an elegant and standard way. All suggestions are welcome !

• Is count(*) really expensive ?

  - by Anil Namde

  I have a page where I have 4 tabs displaying 4 different reports based off different tables. I obtain the row count of each table using a select count(*) from <table> query and display number of rows available in each table on the tabs. As a result, each page postback causes 5 count(*) queries to be executed (4 to get counts and 1 for pagination) and 1 query for getting the report content. Now my question is: are count(*) queries really expensive -- should I keep the row counts (at least those that are displayed on the tab) in the view state of page instead of querying multiple times? How expensive are COUNT(*) queries ?

• iPhone application build fails with "dyld: Library not loaded: /System/[...]" error? Why?

  - by Andrew J. Brehm

  For my own reasons and not for the app store I am referencing the Apple private framework Apple80211 in an iPhone app. I got the framework from an earlier version of the iPhone SDK. I added the "existing framework", verified that that absolute path to the framework is /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/PrivateFrameworks/Apple80211.framework and tried to build the app. But the build (to device) fails with the error dyld: Library not loaded: /System/Library/PrivateFrameworks/Apple80211.framework/Apple80211 Referenced from: /var/mobile/Applications/3691587D-87AF-44EA-A505-F73D17F39B3B/iWire2.app/iWire2 Reason: image not found I cannot figure out why Xcode would look for the library in a /System path (instead of using the path given in the frameworks list) or how to change that behaviour. I tried the tricks I found here and elsewhere for similar (and identical) sitiations: Delete the myusername.* files in the xcodeproj bundle Delete the build directory Clean all targets Start new project Result is always the same. How can I add this (or a) framework to an iPhone project AND get Xcode to at least look at the library located where I point to rather than a location in /System?

• C++ streams question (explanation of comment in code)

  - by skyeagle

  I am playing around with the fastCGI application found here. The following comment is in the code: if (content) delete []content; // If the output streambufs had non-zero bufsizes and // were constructed outside of the accept loop (i.e. // their destructor won't be called here), they would // have to be flushed here. My knowledge of C++ streams is rather weak. Could someone please explain the following: which streambufs are being referred to in the comment? under what conditions would the streambufs had non-zero bufsizes? last but not the least, can someone point to a resource (pun intended) online that provides a clear but gentle introduction to C++ IO streams?

• How to hash and check for equality of objects with circular references

  - by mfya

  I have a cyclic graph-like structure that is represented by Node objects. A Node is either a scalar value (leaf) or a list of n=1 Nodes (inner node). Because of the possible circular references, I cannot simply use a recursive HashCode() function, that combines the HashCode() of all child nodes: It would end up in an infinite recursion. While the HashCode() part seems at least to be doable by flagging and ignoring already visited nodes, I'm having some troubles to think of a working and efficient algorithm for Equals(). To my surprise I did not find any useful information about this, but I'm sure many smart people have thought about good ways to solve these problems...right? Example (python): A = [ 1, 2, None ]; A[2] = A B = [ 1, 2, None ]; B[2] = B A is equal to B, because it represents exactly the same graph. BTW. This question is not targeted to any specific language, but implementing hashCode() and equals() for the described Node object in Java would be a good practical example.

• Why should "miter" joints be slower than others?

  - by Hanno Fietz

  I'm having a graphics problem on drawing lines in Flash Player, where two lines drawn on top of each other with different thickness don't align properly if I use any other JointStyle than MITER. For pictures of the effect, and for the graphics oriented part of the question, see my post over on doctype. However, there's also a second angle on this problem, which is: why should drawing the "mitered" joints be so much slower than others? This seems to be a problem since at least FP 8, but I couldn't find any detailed info on what the problem might be. Is this just an ordinary bug that didn't get fixed yet, or is there something inherently slower about drawing these joints? For example, they seem to have something to do with square roots, but I seriously lack understanding of what this joint style thing is all about, technically. It just looks like some minor detail a graphic designer might worry about. I'm asking because I'm wondering if I can do something to mitergate, er, mitigate, the problem.

• What should be contained in a global Subversion ignore pattern for Visual Studio 2010?

  - by Chris Simmons

  After installing and using Visual Studio 2010, I'm seeing some newer file types (at least with C++ projects ... don't know about the other types) as compared to 2008. e.g. .sdf, .opensdf, which I guess are the replacement for ncb files with Intellisense info stored in SQL Server Compact files? I also notice .log files are generated, which appear to be build logs. Given this, what's safe to add to my global ignore pattern? Off the bat, I'd assume .sdf, .opensdf, but what else?

• Change update value of property (LINQTOSQL)

  - by Dynde

  Hi... I've got an entity object - Customer, with a property called VATRate. This VATRate is in the form of a decimal (0.25). I wanted to be able to enter a percentage value, and save it in the correct decimal value in the database, so I made this custom property: partial class Customer{ public decimal VatPercent { get{ ... //Get code works fine} set { this.VATRate = (value / 100); } } } And then I just bind this property instead of VATRate in my ASPX editTemplate (formview). This actually works - at least one time, when I debug an update, the value is set correctly one time, and then right after it gets set to the old value. I can't really see why it sets the value twice (and with the old value the second time). Can anyone shed some light on this?

• How to Design Programs: An Introduction to Programming and Computing -- teacher guide access

  - by user295683

  Hello -- I'm a biologist switching careers, and trying to learn programming as a result. I stumbled upon the aforementioned book on Amazon, which jived with my liberal arts background. Despite my great satisfaction with the didactic approach, I was frustrated to see that the answers to the exercises are restricted to teachers only. As I am pursuing this endeavor on my own, this restriction dramatically cripples the value of this book. My request to the author's website for access to the answers has not been answered, and I would desperately like to continue with this book. Anyone have any experience dealing with the book's website, or at the very least a torrent of the answers? Otherwise, I suspect I will be relegated to using JavaScript for everything! Thanks!

• How to add response headers based on Content-type; getting Content-type before the response is commi

  - by Bozho

  I want to set the Expires header for all image/* and text/css. I'm doing this in a Filter. However: before calling chain.doFilter(..) the Content-type is not yet "realized" after calling chain.doFilter(..) the Content-type is set, but so is content-length, which forbids adding new headers (at least in Tomcat implementation) I can use the extensions of the requested resource, but since some of the css files are generated by richfaces by taking them from inside jar-files, the name of the file isn't x.css, but is /xx/yy/zz.xcss/DATB/.... So, is there a way to get the Content-type before the response is committed.

• Creating TCP network errors for unit testing

  - by Robert S. Barnes

  I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

• DotNetOpenAuth I need some help please

  - by Nate Gates

  I know this has been posted before, but never really answered, I'm using the DotNetOpenAuth to try and do GoogleID login, and every time I do details = OResponse.GetExtension<ClaimsResponse>(); I always, always, always get back null, I don't get whats the point of the GoogleID if I can't get back any information, I would think at the very least I would get an email address, so I could associate it other login information in my databse. I just don't understand could really use some help, Im probably just looking at openID in the wrong way. I'm using ASP.NET and looking to use openID/Facebook as my sole means of logging in users, I really don't want to mess with membership roles, or extra junk that ASP.NET likes to add.

• How to host a naked domain on a CDN?

  - by rjw79

  If I have a domain that I wish to serve "naked" eg http://examp.le/, and efficiently with a CDN, what are my options? The issue is that the CDNs I looked at all want you to use a CNAME so that they can do geo ip lookup. CNAMES are not meant to be served at the same level as other records, and this apparently breaks some dns resolvers. You at least need SOA and MX records at the same level for a naked domain. The only solutions are: having A records in your own dns, thus skipping the geo ip, or finding a cdn who will allow delegation of the whole domain so they can do geo ip things for the A record directly. I've tried googling and can't find any Cdn who offers this. Any ideas? I looked closely at Amazon cloudfront and rackspace cloudfiles. I couldn't work it out for those.

• Cache images provided through script

  - by Wim Haanstra

  I have a script, which by using several querystring variables provides an image. I am also using URL rewriting within IIS 7.5. So images have an URL like this: http://mydomain/pictures/ajfhajkfhal/44/thumb.jpg or http://mydomain/pictures/ajfhajkfhal/44.jpg This is rewritten to: http://mydomain/Picture.aspx?group=ajfhajkfhal&id=44&thumb=thumb.jpg or http://mydomain/Picture.aspx?group=ajfhajkfhal&id=44 I added caching rules to IIS to cache JPG images when they are requested. This works with my images that are REAL images on the disk. When images are provided through the script, they are somehow always requested through the script, without being cached. The images do not change that often, so if the cache at least is being kept for 30 minutes (or until file change) that would be best. I am using .NET/C# 4.0 for my website. I tried setting several cache options in C#, but I cant seem to find how to cache these images (client-side), while my static images are cached properly.

• Why jquery.animate on a textarea make the blinking cursor disapears?

  - by Tom S.

  Hello everyone. I have the following code $(document).ready(function() { $("#myTextArea").focus(function() { $("#myTextArea").animate({ "height": "75px"}, "normal"); return false; }); to expand a textbox when it gets focus. The expand occurs, however the blinking cursor disapears, at least in Firefox! Edited: The textarea is still focused, and i can type on it. Why does this happen? Is there a way to show it again? Thanks in advance

• Should the name of my classes begin with 'Q' in Qt?

  - by Venemo

  Hello Everyone, When I first started working with Qt, it was extremely annoying that every class has a name beginning with 'Q', but now I've got used to it. I'm using Qt Creator, and it highlights code quite well. However, it only highlights class names beginning with 'Q'. And it highlights everything beginning with 'Q' even if there is no such type. It doesn't highlight custom class names. That makes me wonder, should I also begin all my class names with 'Q'? Or at least the reusable ones? (I mean, those that I put in a class library, or reuse in another app.) I've seen several places where they named their classes this way. Is it a good thing? I found this page about Qt's naming conventions, but it doesn't deal with this question. Also, I don't understand why Qt doesn't use namespaces.

• Java technologies for web-development.

  - by Alex

  Hello. I'm PHP-programmer, but I'm extremely interested in learning Java. So I decided to change speciality from PHP to Java. At the moment I have an opportunity to try to make quite simple web-application (it should contain 2-3 forms, several pages with information from the database and authorization module) and also I have a chance to choose any technology I want. Besides I have about 3 months for this task. I've decided to develop site with Java technologies for the purpose of studying. I've already read a book about Java ("Java2 Complete Reference" by P.Naughton) and currently I'm reading "Thinking in Java" by B.Eckel. I clearly understand it's not enough for efficient development, but I want, at least, to try. I would be very appreciated for the advises, which framework (for example) or technology to choose (Spring, Grails etc.) and what primary aspects and technologies of Java should I pay attention to? Thank you in advance.

• Why do Java and C# not have implicit conversions to boolean?

  - by Shaun

  Since I started Java it's been very aggravating for me that it doesn't support implicit conversions from numeric types to booleans, so you can't do things like: if (flags & 0x80) { ... } instead you have to go through this lunacy: if ((flags & 0x80) != 0) { ... } It's the same with null and objects. Every other C-like language I know including JavaScript allows it, so I thought Java was just moronic, but I've just discovered that C# is the same (at least for numbers, don't know about null/objects): http://msdn.microsoft.com/en-us/library/c8f5xwh7(VS.71).aspx Microsoft changed it on purpose from C++, so why? Clearly I'm missing something. Why change (what I thought was) the most natural thing in the world to make it longer to type? What on Earth is wrong with it?

• Package names - impl v internal

  - by Ben J

  In my time of digging around Java APIs I have come across both impl and internal packages. Up until now I never really thought about the difference - as with all enterprisey Java apps, I figured they just meant that "actual implementation in here; you (API user) should be really using the interface. Go away." A little bit of digging around Stack Overflow seems to suggest that the internal package at least can have some security placed around it. So, what is the difference? I don't think it is a matter of taste because I have seen APIs with both.

• inheriting scope from a has_many relationship

  - by hb922

  I am using ruby on rails 3.1 and have 2 models, an event and a group. Each event has_many groups, but has to have at least one "master" group, where the column :is_master = true Class Group < ActiveRecord::Base has_many :users belongs_to :event scope :master, where (:is_master => true) end Class Event< ActiveRecord::Base has_many :groups def master_group groups.master end end I want to be able to default all properties of the master group to the event, so for example, event.users.count should be the same as event.master_group.users.count. Is there any way to do something like this? Can I do a has_many :through = master_group? Am I approaching this the wrong way? Thanks!

• Is there a unified way to know if a node is visible or not?

  - by zneak

  Hello guys, I'd like to be able to know if a node is visible and rendered on screen. As far as I know, there are at least 3 standard and easy ways of making HTML nodes not visible: Setting opacity: 0; Setting display: none; Setting visibility: hidden. I could check for just these three, but I'm afraid people can get creative when it comes to ways of hiding contents: Sending the element offscreen using negative margins; Using a width or height of 0 and hiding overflow; many more I trust people to have developed. So I was wondering if there is a standard way of determining if a node is rendered to the screen. I'm pretty sure all major browsers determine it for themselves to accelerate drawing, so maybe it's somehow exposed.
