• Install h5py in Mac OS X 10.6.3

  - by zyq524

  I'm trying to install h5py in Mac OS X 10.6.3. First I installed HDF5 1.8, which used the following commands: ./configure \ --prefix=/Library/Frameworks/Python.framework/Versions/Current \ --enable-shared \ --enable-production \ --enable-threadsafe \ CPPFLAGS=-I/Library/Frameworks/Python.framework/Versions/Current/include \ LDFLAGS=-L/Library/Frameworks/Python.framework/Versions/Current/lib make make check sudo make install Then install h5py: /Library/Frameworks/Python.framework/Versions/Current/bin/python \ setup.py \ build \ --api=18 \ --hdf5=/Library/Frameworks/Python.framework/Versions/Current Then I got the errors: Configure: Autodetecting HDF5 settings...

• Have you had DLL's fail after upgrading to 64 bit server?

  - by quakkels

  Hey All, I'm wondering if anyone else has experienced failed DLL's after upgrading their servers. My company is in the process of upgrading our code and server's after ten years of using classic ASP. We've set up our new server running Windows 2008 and IIS 7. Our classic ASP code and our new asp.net mvc code work pretty well. Our problems started happening when we began moving our old websites to the new server. When trying to load the page on the actual server machine's browser, we initially got a 500 error. If we refreshed the page then some of the page would load but then display an error: Server object error 'ASP 0177 : 800401f3' Server.CreateObject Failed /folder/scriptname.asp, line 24 800401f3 btw: On remote machines we would just get 500 errors. Line 24 is the first executable code in the script: '23 lines of comments set A0SQL_DATA = server.createobject("olddllname.Data") 'the rest of the script That specific line is trying to use a ten year old DLL to create a server object. I don't think the server configuration is a problem because I'm able to create "adodb.recordset" server objects without any problems. Is there an issue when running correctly registered old DLL's on 64 bit systems? Is there a way to get old DLL's working on 64 bit systems?

• How can I get JUnit test (driven from Ant script) to dump the stack of exception that causes failure

  - by Matt Wang

  We run JUnit test from Ant script, as follows. When the test failed, I expect it to output the stack dump of the exception that casuses the failure, but it doesn't.

• Memory efficient collection class

  - by Joe

  I'm building an array of dictionaries (called keys) in my iphone application to hold the section names and row counts for a tableview. the code looks like this: [self.results removeAllObjects]; [self.keys removeAllObjects]; NSUInteger i,j = 0; NSString *key = [NSString string]; NSString *prevKey = [NSString string]; if ([self.allResults count] > 0) { prevKey = [NSString stringWithString:[[[self.allResults objectAtIndex:0] valueForKey:@"name"] substringToIndex:1]]; for (NSDictionary *theDict in self.allResults) { key = [NSString stringWithString:[[theDict valueForKey:@"name"] substringToIndex:1]]; if (![key isEqualToString:prevKey]) { NSDictionary *newDictionary = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:i],@"count", prevKey,@"section", [NSNumber numberWithInt:j], @"total",nil]; [self.keys addObject:newDictionary]; prevKey = [NSString stringWithString:key]; i = 1; } else { i++; } j++; } NSDictionary *newDictionary = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:i],@"count", prevKey,@"section", [NSNumber numberWithInt:j], @"total",nil]; [self.keys addObject:newDictionary]; } [self.tableview reloadData]; The code works fine first time through but I sometimes have to rebuild the entire table so I redo this code which orks fine on the simulator, but on my device the program bombs when I execute the reloadData line : malloc: *** mmap(size=3772944384) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug malloc: *** mmap(size=3772944384) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Program received signal: “EXC_BAD_ACCESS”. If I remove the reloadData line the code works on the device. I'm wondering if this is something to do with the way I've built the keys array (ie using autoreleased strings and dictionaries).

• socket timeout and remove O_NONBLOCK option

  - by juxstapose

  Hello, I implemented a socket timeout and retry but in order to do it I had to set the socket as a non-blocking socket. However, I need the socket to block. This was my attempt at a solution to these two problems. This is not working. Subsequent send calls block but never send any data. When I connect without the select and the timeout, subsequent send calls work normally. References: C: socket connection timeout How to reset a socket back to blocking mode (after I set it to nonblocking mode)? Code: fd_set fdset; struct timeval tv; fcntl(dsock, F_SETFL, O_NONBLOCK); tv.tv_sec = theDeviceTimeout; tv.tv_usec = 0; int retries=0; logi(theLogOutput, LOG_INFO, "connecting to device socket num retrys: %i", theDeviceRetry); for(retries=0;retries<theDeviceRetry;retries++) { connect(dsock, (struct sockaddr *)&daddr, sizeof daddr); FD_ZERO(&fdset); FD_SET(dsock, &fdset); if (select(dsock + 1, NULL, &fdset, NULL, &tv) == 1) { int so_error; socklen_t slen = sizeof so_error; getsockopt(dsock, SOL_SOCKET, SO_ERROR, &so_error, &slen); if (so_error == 0) { logi(theLogOutput, LOG_INFO, "connected to socket on port %i on %s", theDevicePort, theDeviceIP); break; } else { logi(theLogOutput, LOG_WARN, "connect to %i failed on ip %s because %s retries %i", theDevicePort, theDeviceIP, strerror(errno), retries); logi(theLogOutput, LOG_WARN, "failed to connect to device %s", strerror(errno)); logi(theLogOutput, LOG_WARN, "error: %i %s", so_error, strerror(so_error)); continue; } } } int opts; opts = fcntl(dsock,F_GETFL); logi(theLogOutput, LOG_DEBUG, "clearing nonblock option %i retries %i", opts, retries); opts ^= O_NONBLOCK; fcntl(dsock, F_SETFL, opts);

• How to avoid user keep trying login using Ruby on Rails?

  - by Tattat

  I want to create a login page, it can easy implement using Ruby on Rails. But the login is very simple, but I want more security. I want to stop the user keep trying the password. So, I have some ideas on that. First, stop login feature if the user keep trying the password for 15 mins. After the user login fail 5 times in 15 mins, the system should not allow the user login again in next 15 mins, ever his/her password is correct. Second, I want to add a human verification, after the user tried 5 times. After the user wait for 15 mins to login, I want to add an addition verification to the user. I want the user click the password, and the CAPTCHA image. If one of them is failed, they still can't login the system. He/She have 5 times to try, if he / she failed again, he/she need to want another 15 mins. Third, After the user tried 15 times, and still can't get into the system. I want to lock the user account, the user will receive an email, with a link to assign the password again. So, the question is "Is there any library to implement such authorization easily?" I know it can be implemented using code, but using library is much convenient. Also, I want to ask is there any security suggestion for that? thank u.

• Problem convert column values from VARCHAR(n) to DECIMAL

  - by Kevin Babcock

  I have a SQL Server 2000 database with a column of type VARCHAR(255). All the data is either NULL, or numeric data with up to two points of precision (e.g. '11.85'). I tried to run the following T-SQL query but received the error 'Error converting data type varchar to numeric' SELECT CAST([MyColumn] AS DECIMAL) FROM [MyTable]; I tried a more specific cast, which also failed. SELECT CAST([MyColumn] AS DECIMAL(6,2)) FROM [MyTable]; I also tried the following to see if any data is non-numeric, and the only values returned were NULL. SELECT ISNUMERIC([MyColumn]), [MyColumn] FROM [MyTable] WHERE ISNUMERIC([MyColumn]) = 0; I tried to convert to other data types, such as FLOAT and MONEY, but only MONEY was successful. So I tried the following: SELECT CAST(CAST([MyColumn] AS MONEY) AS DECIMAL) FROM [MyTable]; ...which worked just fine. Any ideas why the original query failed? Will there be a problem if I first convert to MONEY and then to DECIMAL? Thanks!

• How can i iterate through QListWidget items and work with each item?

  - by Hossein

  In CSharp its as simple as writting : listBox1.Items.Add("Hello"); listBox1.Items.Add("There"); foreach (string item in listBox1.Items ) { MessageBox.Show(item.ToString()); } and i can easily add different objects to a list box and then retrieve them using foreach. I tried the same approach in Qt 4.8.2 but it seems they are different.though they look very similar at first.I found that Qt supports foreach so i went on and tried something like : foreach(QListWidgetItem& item,ui->listWidget->items()) { item.setTextColor(QColor::blue()); } which failed clearly.It says the items() needs a parameter which confuses me.I am trying to iterate through the ListBox itself, so what does this mean? I tried passing the ListBox object as the parameter itself this again failed too: foreach(QListWidgetItem& item,ui->listWidget->items(ui->listWidget)) { item.setTextColor(QColor::blue()); } So here are my questions: How can I iterate through a QListWidget items in Qt? Can i store objects as items in QListWidgets like C#? How can i convert an object in QListWidgets to string(C#s ToString counter part in Qt) ? (suppose i want to use a QMessagBox instead of that setTextColor and want to print out all string items in the QlistWidget.)

• Need to reload current_cart to get the test passed

  - by leomayleomay

  I'm testing my online store app with RSpec, here's what I'm doing: # spec/controllers/line_items_controller_spec.rb require 'spec_helper' describe LineItemsController do describe "POST 'create'" do before do @current_cart = Factory(:cart) controller.stub!(:current_cart).and_return(@current_cart) end it 'should merge two same line_items into one' do @product = Factory(:product, :name => "Tee") post 'create', {:product_id => @product.id} post 'create', {:product_id => @product.id} assert LineItem.count.should == 1 assert LineItem.first.quantity.should == 2 end end end # app/controllers/line_items_controller.rb class LineItemsController < ApplicationController def create current_cart.line_items.each do |line_item| if line_item.product_id == params[:product_id] line_item.quantity += 1 if line_item.save render :text => "success" else render :text => "failed" end return end end @line_item = current_cart.line_items.new(:product_id => params[:product_id]) if @line_item.save render :text => "success" else render :text => "failed" end end end The problem right now is it never added up two line_items having the same product into one, because the second time I entered into the line_items_controller#create, the current_cart.line_items is [], I have run current_cart.reload to get the test passed, any idea what's going wrong?

• What VC++ compiler/linker does when building a C++ project with Managed Extension

  - by ???

  The initial problem is that I tried to rebuild a C++ project with debug symbols and copied it to test machine, The output of the project is external COM server(.exe file). When calling the COM interface function, there's a RPC call failre: COMException(0x800706BE): The remote procedure call failed. According to the COM HRESULT design, if the FACILITY code is 7, it's actually a WIN32 error, and the win32 error code is 0x6BE, which is the above mentioned "remote procedure call failed". All I do is replace the COM server .exe file, the origin file works well. When I checked into the project, I found it's a C++ project with Managed Extension. When I checking the DLL with reflector, it shows there's 2 additional .NET assembly reference. Then I checked the project setting and found nothing about the extra 2 assembly reference. I turned on the show includes option of compiler and verbose library of linker, and try to analyze whether the assembly is indirectly referenced via .h file. I've collect all the .h file and grep all the files with '#using' '#import' and the assembly file itself. There really is a '#using ' in one of the .h file but not-relevant to the referenced assembly. And about the linked .lib library files, only one of the .lib file is a side-product of another managed-extension-enabled C++ project, all others are produced by a pure, traditional C++ project. For the managed-extension-enabled C++ project, I checked the output DLL assembly, it did NOT reference to the 2 assembly. I even try to capture the access of the additional assembly file via sysinternal's filemon and procmon, but the rebuild process does NOT access these file. I'm very confused about the compile and linking process model of a VC++/CLI project, where the additional assembly reference slipped into the final assembly? Thanks in advance for any of your help.

• application trying to connect to mirrored sql db

  - by hp

  Hello, We have 4 web servers that host our asp.net (3.5) application. Randomly, we get error messages like : 1) "Login failed for user 'userid'" 2) "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" we are running sql2005 and have a principle and a mirror db (sync). When these exceptions are thrown, I look at the SQL error logs on the mirrored db and noticed the failed login messages in there. The principle db is running fine and the other web apps are working great. this will happen for maybe 10 min, then the app pool recycles and it starts hitting the principle db again. Is there a configuration I have incorrect? my theory is that our principle db is forwarding the request to the mirror, but that should never happen. any help??

• Error copying file from app bundle

  I used the FireFox add-on SQLite Manager, created a database, which saved to my desktop as "DB.sqlite". I copied the file into my supporting files for the project. But when I run the app, immediately I get the error "Assertion failure in -[AppDelegate copyDatabaseIfNeeded], /Users/Mac/Desktop/Note/Note/AppDelegate.m:32 2014-08-19 23:38:02.830 Note[28309:60b] Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Failed to create writable database file with message 'The operation couldn’t be completed.

• Silverlight Business Application template with WCF is throwing warning.

  - by Manoj

  Hi, I am using the Silvelight Business Application template. I wrote a function which uses Membership.getUserList function to return the user list. I tried exposing it as Service using WCF. But when I try to compile the client side code it throws a warning saying "Client Proxy Generation for user_authentication.Web.Service1 failed'. Why does it happen? The complete warning message is: Warning 4 Client proxy generation for service 'user_authentication.Web.Service1' failed: Generating metadata files... Warning: Unable to load a service with configName 'user_authentication.Web.Service1'. To export a service provide both the assembly containing the service type and an executable with configuration for this service. Details:Either none of the assemblies passed were executables with configuration files or none of the configuration files contained services with the config name 'user_authentication.Web.Service1'. Warning: No metadata files were generated. No service contracts were exported. To export a service, use the /serviceName option. To export data contracts, specify the /dataContractOnly option. This can sometimes occur in certain security contexts, such as when the assembly is loaded over a UNC network file share. If this is the case, try copying the assembly into a trusted environment and running it.

• How to parse time stamps with Unicode characters in Java or Perl?

  - by ram

  I'm trying to make my code as generic as possible. I'm trying to parse install time of a product installation. I will have two files in the product, one that has time stamp I need to parse and other file tells the language of the installation. This is how I'm parsing the timestamp public class ts { public static void main (String[] args){ String installTime = "2009/11/26 \u4e0b\u5348 04:40:54"; //This timestamp I got from the first file. Those unicode charecters are some Chinese charecters...AM/PM I guess //Locale = new Locale();//don't set the language yet SimpleDateFormat df = (SimpleDateFormat)DateFormat.getDateTimeInstance(DateFormat.DEFAULT,DateFormat.DEFAULT); Date instTime = null; try { instTime = df.parse(installTime); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println(instTime.toString()); } } The output I get is Parsing Failed java.text.ParseException: Unparseable date: "2009/11/26 \u4e0b\u5348 04:40:54" at java.text.DateFormat.parse(Unknown Source) at ts.main(ts.java:39) Exception in thread "main" java.lang.NullPointerException at ts.main(ts.java:45) It throws exception and at the end when I print it, it shows some proper date... wrong though. I would really appreciate if you could clarify me on these doubts How to parse timestamps that have unicode characters if this is not the proper way? If parsing is failed, how could instTime able to hold some date, wrong though? I know its some chinese,Korean time stamps so I set the locale to zh and ko as follows.. even then same error comes again Locale = new Locale("ko"); Locale = new Locale("ja"); Locale = new Locale("zh"); How can I do the same thing in Perl? I can't use Date::Manip package; Is there any other way?

• Strategies for Synchronizing Data Between a Rails App and iPhone App

  - by jessecurry

  I've written many iPhone Applications that have pulled data from web services and I've worked on synchronizing data between an iPhone App and a Web Application, but I've always felt that there is probably a better way to handle the synchronization. I'd like to know what strategies you have used to synchronize data between your iPhone(read: mobile) Apps and your Rails(read: web) Applications. Are there any strategies that scale particularly well? How have you dealt with large amounts of data? (Do you use paged responses?) How do you make sure that data is not overwritten? Is there a reason to avoid Ruby on Rails? if so, can you suggest an alternative? What is better about the alternative? What strategies have failed? Why do you believe that those strategies failed? I would like to be able to keep all of the data modifications on the server, but the particular application I am about to start work on will need the ability to operate while disconnected from the network. The user will be able to update data on the mobile device and update data through the web application. When the user's mobile device connects to the server any local changes will be pushed to the server.

• using usort to re-arrange multi-dimension array

  - by Thomas Bennett

  I have a large array: [0] => stdClass Object ( [products] => Array ( [0] => stdClass Object ( [body_html] => bodyhtml [published_at] => 2012-12-16T23:59:18+00:00 [created_at] => 2012-12-16T11:30:24+00:00 [updated_at] => 2012-12-18T10:52:14+00:00 [vendor] => Name [product_type] => type ) [1] => stdClass Object ( [body_html] => bodyhtml [published_at] => 2012-12-16T23:59:18+00:00 [created_at] => 2012-12-16T10:30:24+00:00 [updated_at] => 2012-12-18T10:52:14+00:00 [vendor] => Name [product_type] => type ) ) ) and I need to arrange each of the products by the date they where created... I've tried and failed all kinds of usort, ksort, uksort techniques to try and get it to be in a specific order (chronological) but failed! any guidance would be most appreciated
