  • Is redis a durable datastore?

    - by allyourcode
    By "durable" I mean, the server can crash at any time, and as long as the disk remains in tact, no data is lost (see ACID). Seems like that's what journaling mode is for, but if you enable journaling, doesn't that defeat the purpose of operating on in-memory data? Read operations might not be affected by journaling, but it seems like journaling would kill your write performance.

  • Dynamically generate PDF and email it using django

    - by Shane
    I have a django app that dynamically generates a PDF (using reportlab + pypdf) from user input on an HTML form, and returns the HTTP response with an application/pdf MIMEType. I want to have the option between doing the above, or emailing the generated pdf, but I cannot figure out how to use the EmailMessage class's attach(filename=None, content=None, mimetype=None) method. The documentation doesn't give much of a description of what kind of object content is supposed to be. I've tried a file object and the above application/pdf HTTP response. I currently have a workaround where my view saves a pdf to disk, and then I attach the resulting file to an outgoing email using the attach_file() method. This seems wrong to me, and I'm pretty sure there is a better way.

  • Concurrent use of System.Net.Mail.SendAsync?

    - by Bob
    I want to use System.Net.Mail.SendAync in an ASP.NET MVC2 application. I see that it throws an InvalidOperationException if there is already a SendAsync call in progress. Does this mean only one SendAsync is allowed per host, or per thread? For example, if I simultaneously have 2 web users from 2 different remote hosts, can each use SendAsync at the same time?

  • UIBarButtonItem: target-action not working?

    - by Jacob Relkin
    Hey fellas, I've got a custom view inside of a UIBarButtonItem, set by calling -initWithCustomView. OK, so the view renders fine, but when I tap it, it doesn't call the method that I set as the UIBarButtonItem's action property. Oh, and I have verified that my -deselectAll method works fine. Here's my code: UIImageView *SOCImageView = [[ UIImageView alloc ] initWithImage:[ UIImage imageNamed: @"cancel_wide.png" ] ]; SOItem.leftBarButtonItem = [[ UIBarButtonItem alloc ] initWithCustomView: SOCImageView ]; [ SOCImageView release ]; [ SOItem.leftBarButtonItem setTarget: self ]; [ SOItem.leftBarButtonItem setAction: @selector( deselectAll ) ]; Thanks a million

  • Why does WPF toggle button pulse once unchecked

    - by randyc
    Wihtin a Desktop app I have a toggle button: For the Checked event I am setting a value and then executing a method FilterView(); //ommitting code Unchecked state is just the opposite. resets a variable and executed the method again The question I have is I noticed when I uncheck the toggle button the button continues to pulse or flash ( going from blue to chrome) as if it still has focus. The button will stay like this until another button is clicked. Is there a way to remove this focus so that when the button is unchecked the button goes back to a unchecked state without the flashing / pulsing color. As you can see from above this is a standard toggle button no styles or custom I tested this on just a regular button and I found the same occured when clicked the button will continue to pulse / flash until another button is clicked. How do you work around this or prevent this effect from happening. Thank you

  • Limit number of charchters in uitextview !

    - by hib
    Hello All , I am giving a text view to tweet some string . I am applying the following method to restrict the number of characters to 140 in length. - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{ if([text isEqualToString:@"\b"]){ DLog(@"Ohoooo"); return YES; }else if([[textView text] length] > 140){ return NO; } return YES; } The code is working nicely except the first condition that backspace is not working. suppose that I have reached the limit of 140 characters so that the method will give me false and the user can not insert more characters but after that when I try to delete some characters the text view behave as it is disabled . So the question how do delete characters from textview.text or re-enable the text view .

  • Is it fair for us to conclude XOR string encryption is less secure than well known encryption (Say Blowfish)

    - by Yan Cheng CHEOK
    I was wondering, is it fair to conclude, XOR string encryption is less secure than other encryption method, say Blowfish This is because for both methods, their input are Unencrypted string A secret key string XOR(string value,string key) { string retval(value); short unsigned int klen=key.length(); short unsigned int vlen=value.length(); short unsigned int k=0; short unsigned int v=0; for(v;v<vlen;v++) { retval[v]=value[v]^key[k]; k=(++k<klen?k:0); } return retval; } Is there any proof that XOR encryption method is more easy to be "broken" than Blowfish if the same key is being chosen?

  • Why does my UIActivityIndicatorView only display once?

    - by Schwigg
    I'm developing an iPhone app that features a tab-bar based navigation with five tabs. Each tab contains a UITableView whose data is retrieved remotely. Ideally, I would like to use a single UIActivityIndicatorView (a subview of the window) that is started/stopped during this remote retrieval - once per tab. Here's how I set up the spinner in the AppDelegate: - (void)applicationDidFinishLaunching:(UIApplication *)application { [window addSubview:rootController.view]; activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [activityIndicator setCenter:CGPointMake(160, 200)]; [window addSubview:activityIndicator]; [window makeKeyAndVisible]; } Since my tabs were all performing a similiar function, I created a base class that all of my tabs' ViewControllers inherit from. Here is the method I'm using to do the remote retrieval: - (void)parseXMLFileAtURL:(NSString *)URL { NSAutoreleasePool *apool = [[NSAutoreleasePool alloc] init]; AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"parseXMLFileAtURL started."); [appDelegate.activityIndicator startAnimating]; NSLog(@"appDelegate.activityIndicator: %@", appDelegate.activityIndicator); articles = [[NSMutableArray alloc] init]; NSURL *xmlURL = [NSURL URLWithString:URL]; rssParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; [rssParser setDelegate:self]; [rssParser setShouldProcessNamespaces:NO]; [rssParser setShouldReportNamespacePrefixes:NO]; [rssParser setShouldResolveExternalEntities:NO]; [rssParser parse]; NSLog(@"parseXMLFileAtURL finished."); [appDelegate.activityIndicator stopAnimating]; [apool release]; } This method is being called by each view controller as follows: - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; if ([articles count] == 0) { NSString *path = @"http://www.myproject.com/rss1.xml"; [self performSelectorInBackground:@selector(parseXMLFileAtURL:) withObject:path]; } } This works great while the application loads the first tab's content. I'm presented with the empty table and the spinner. As soon as the content loads, the spinner goes away. Strangely, when I click the second tab, the NSLog messages from the -parseXMLFileAtURL: method show up in the log, but the screen hangs on the first tab's view and I do not see the spinner. As soon as the content is done downloading, the second tab's view appears. I suspect this has something to do with threading, with which I'm still becoming acquainted. Am I doing something obviously wrong here?

  • Subclass of Subclass fluent nHibernate

    - by Xavier Hayoz
    Hi all My model looks like this: public class SelectionItem : BaseEntity // BaseEntity ==> id, timestamp stuff {//blabla} public class Size : SelectionItem {//blabla} public class Adultsize : Size {//blabla} I would like to use class-hierarchy-per-table-method of fluent nhibernate public class SelectionItemMap : BaseEntityMap<Entities.SelectionItem.SelectionItem> { public SelectionItemMap() { Map(x => x.Name); Map(x => x.Picture); Map(x => x.Code); DiscriminateSubClassesOnColumn("SelectionItemType"); } } and reset a DiscriminateSubClassesOnColumn on the following subclass: public class SizeMap : SubclassMap<Size> { DiscriminateSubClassesOnColumn("SizeType") } public Adultsize : SubclassMap<Adultsize> {} But this doesn't work. I found a solution on the web: link text but this method is depreciated according to resharper. How to solve it? thank you for further informations.

  • What are your favorite "yak shaving" euphemisms?

    - by dacracot
    Noun yak shaving (uncountable) (idiomatic) Any apparently useless activity which, by allowing you to overcome intermediate difficulties, allows you to solve a larger problem. I was doing a bit of yak shaving this morning, and it looks like it might have paid off. So I'm after phrases like "yak shaving" that mean something to the developer community that non-developers don't understand. Not anecdotes.

  • Delphi Prism getting Unknown Identifier "DllImport" error

    - by Robo
    I'm trying to call Window's SendMessage method in Delphi Prism, I've declared the class as follow: type MyUtils = public static class private [DllImport("user32.dll", CharSet := CharSet.Auto)] method SendMessage(hWnd:IntPtr; Msg:UInt32; wParam:IntPtr; lParam:IntPtr):IntPtr; external; protected public end; When I tried to compile, I get the error Unknown identifier "DllImport" I used this as an example, http://stackoverflow.com/questions/2708520/how-to-call-function-createprocess-in-delphi-prism and the syntax looks the same. Is there a setting I need to enable, or do I have a syntax error?

  • What is O(n log n) or O(n log(log n))

    - by Mark Tomlin
    What does O, if indeed it is a Oh (As in the letter O) not the number Zero (0) mean? I think the n would be number, but I'm not sure as I'm not a 'real' computer programmer, just a hobbyist. And log would be logarithmic function, but I only know that because of smarter people then I have told me this, while never really explaining what a logarithm is. So please, in plain English, explain what this is, and the differences between the two (such as their applications.

  • _mask and Rails

    - by Eric Koslow
    So I am trying to get the cancan gem to work with my rails 3 app and I've hit a problem. I tried to copy the code that Ryan Bates (the creator of the gem) used in his screen cast, but I get an error saying that roles_mask is not a method. I figure that the _mask method was removed from Ruby/Rails at some point, and I'm now wondering what is the replacement. Here's the code in my user.rb model: named_scope :with_role, lambda { |role| {:conditions => "roles_mask & #{2**ROLES.index(role.to_s)} > 0 "} } ROLES = %w[admin student principal admissions] def roles=(roles) self.roles_mask = (roles & ROLES).map { |r| 2**ROLES.index(r) }.sum end def roles ROLES.reject { |r| ((roles_mask || 0) & 2**ROLES.index(r)).zero? } end def role? roles.include? role.to_s end def role_symbols roles.map(&:to_sym) end I'm using Rails 3 and Ruby 1.9.2dev Thank you

  • Can someone clarify what this Joel On Software quote means?

    - by Bob
    I was reading Joel On Software today and ran across this quote: Without understanding functional programming, you can't invent MapReduce, the algorithm that makes Google so massively scalable. The terms Map and Reduce come from Lisp and functional programming. MapReduce is, in retrospect, obvious to anyone who remembers from their 6.001-equivalent programming class that purely functional programs have no side effects and are thus trivially parallelizable. What does he mean when he says functional programs have no side effects? And how does this make parallelizing trivial?

  • How to Connect Crystal Reports to MySQL directly by C# code without DSN or a DataSet

    - by Yanko Hernández Alvarez
    How can I connect a Crystal Report (VS 2008 basic) to a MySQL DB without using a DSN or a preload DataSet using C#? I need install the program on several places, so I must change the connection parameters. I don't want to create a DSN on every place, nor do I want to preload a DataSet and pass it to the report engine. I use nhibernate to access the database, so to create and fill the additional DS would take twice the work and additional maintenance later. I think the best option would be to let the crystal reports engine to connect to MySQL server by itself using ODBC. I managed to create the connection in the report designer (VS2008) using the Database Expert, creating an ODBC(RDO) connection and entering this connection string "DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain" and in the "Next" page filling the "User ID", "Password" and "Database" parameters. I didn't fill the "Server" parameter. It worked. As a matter of fact, if you use the former connection string, it doesn't matter what you put on the "Server" parameter, it seems the parameter is unused. On the other hand, if you use "DRIVER={MySQL ODBC 5.1 Driver}" as a connection string and later fill the "Server" parameter with the FQDN of the server, the connection doesn't work. How can I do that by code? All the examples I've seen till now, use a DSN or the DataSet method. I saw the same question posted but for PostgreSQL and tried to adapt it to mysql, but so far, no success. The first method: Rp.Load(); Rp.DataSourceConnections[0].SetConnection("DRIVER={MySQL ODBC 5.1 Driver};SERVER=myserver.mydomain", "database", "user", "pass"); Rp.ExportToDisk(ExportFormatType.PortableDocFormat, "report.pdf"); raise an CrystalDecisions.CrystalReports.Engine.LogOnException during ExportToDisk Message="Logon failed.\nDetails: IM002:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified.\rError in File temporal file path.rpt:\nUnable to connect: incorrect log on parameters. the InnerException is an System.Runtime.InteropServices.COMException with the same message and no InnerException The "no default driver specified" makes me wonder if the server parameter is unused here too (see above). In that case: How can I specify the connection string? I haven't tried the second method because it doesn't apply. Does anybody know the solution?

  • Gwt-gdata authentication

    - by Raffo
    Hi guys, I'm writing an application with GWT and I found on the internet that there's a library to use easily gdata features. In particular I need to use the integration with Google Calendar. I followed the official guide on gwt-gdata site to do the authentication ( http://code.google.com/p/gwt-gdata/wiki/GettingStarted ) but unfortunately, I got an error. This is the error: 17:59:12.463 [ERROR] [testmappa] Unable to load module entry point class testMappa.client.TestMappa (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google.accounts is undefined fileName: http://127.0.0.1:8888 lineNumber: 29 stack: ("http://www.google.com/calendar/feeds/")@http://127.0.0.1:8888:29 connect("http://127.0.0.1:8888/TestMappa.html?gwt.codesvr=127.0.0.1:9997","`gL1<a3s4B&Y{(Ci","127.0.0.1:9997","testmappa","2.0")@:0 ((void 0),"testmappa","http://127.0.0.1:8888/testmappa/")@http://127.0.0.1:8888/testmappa/hosted.html?testmappa:264 z()@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:2 (-2)@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:8 at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:195) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.accounts.client.User.login(User.java) at testMappa.client.TestMappa.onModuleLoad(TestMappa.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java:369) at com.google.gwt.dev.shell.OophmSessionHandler.loadModule(OophmSessionHandler.java:185) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:380) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:637) I'm not able to understand the reason of this error. My code is simply: String scope = "http://www.google.com/calendar/feeds/"; User.login(scope); And as far as I know it should work as it is. I don't know what to do and I'm here to ask how to solve this problem and if I can directly use gdata native java library, but I believe this other thing is not possible to be done for client-side gwt code (since the code is going to be converted to javascript). Thank you.

  • Serializing data using IEnumerable<T> with WebGet

    - by Jim
    possible duplicate: Cannot serialize parameter of type ‘System.Linq.Enumerable… ’ when using WCF, LINQ, JSON Hi, If my method signiature looks like this, it works fine. [WebGet] MyClass[] WebMethod() If the signiature looks like this [WebGet] IEnumerable<T> WebMethod() I get the following error: Cannot serialize parameter of type 'X.Y.Z.T+<WebMethod>d__2c' (for operation 'WebMethod', contract 'IService') because it is not the exact type 'System.Collections.Generic.IEnumerable`1[X.Y.Z.T]' in the method signature and is not in the known types collection. In order to serialize the parameter, add the type to the known types collection for the operation using ServiceKnownTypeAttribute. I have tried adding. ServiceKnownType(typeof(IEnumerable)) Same error. Is this a bug in 2010 beta 2, or is this likely to be correct going forward? Thanks

  • UIPickerView selectedRowInComponent: returns stale data after code adjusts it

    - by Eric Lloyd
    I have a UIPickerView with multiple components. Some values are grayed out, and my pickerView:didSelectRow:inComponent honors this by shifting the picker component in question to the nearest valid value, much as UIDatePicker moves from "30" to "28" when you select "February". Then it calls a delegate method to announce the adjusted value. When my adjuster method calls my UIPickerView's selectRow:inComponent:animated:YES, the value on screen is correct, but the values from selectedRowInComponent: are stale (from before the adjustment for gray values). However, if I call selectRow:inComponent:animated:NO, the returned values are correct, but the lack of animation is jarring. I've tried wrapping the adjustment in a beginAnimations:/commitAnimations block and catching the values in UIView's +animationDidStopSelector, but I still get stale values. Has anyone run into this before?
