  • [Visual C++]Forcing memory alignment of variables/data-structures

    - by John
    I'm looking at using SSE and I gather aligning data on 16byte boundaries is recommended. There are two cases to consider: float data[4]; struct myystruct { float x,y,z,w; }; I'm not sure the first case can be done explicitly, though there's perhaps a compiler option I could use? In the second case I remember being able to control packing in old versions of GCC several years back, is this still possible?

  • How to get properties from Cassandra with get_slice in Erlang?

    - by Zubair
    I am using Erlang to interface with Cassandra and I cannot get the get_slice command to return a list of all the columns of a row. I use: X = thrift_client:call( C, 'get_slice', [ "Keyspace1", K, #columnParent{column_family="KeyValue"}, #slicePredicate{}, 1 ] ), : but I get back : invalidRequestException,<<"predicate column_names and slice_range may not both be null">> : However, using the cassandra-cli interface this works fine. Any ideas?

  • Options for open source front end for C++

    - by Arpan
    I am looking for options for an open source C++ front end that I could customize for my requirements. I do not need the back end implementation, just that it would help to find a fast and relatively bug free C++ front end that supports most standard features. Any suggestions? [I did google, clang seems to be an option but I don't have any experience with llvm] Arpan

  • MKMapView maptype not changing!

    - by TheLearner
    I cannot understand why my MKMapView does not want to change to satellite view. This method is called and case 1 is called I have stepped over it but it simply does not change to satellite type it always changes to standard. It only works when it goes back to Map type. Anyone have any ideas? - (IBAction)mapSatelliteSegmentControlTapped:(UISegmentedControl *)sender { switch (sender.selectedSegmentIndex) { case 1: //Satellite self.mapView.mapType = MKMapTypeSatellite; default: //Map self.mapView.mapType = MKMapTypeStandard; } }

  • Switching from PHP to Ruby - is it the answer to performance?

    - by Industrial
    Hi everyone, I get more often the answer, when asking performance related stuff regarding PHP applications, that PHP really isn't the language for high-performance applications, and that a compiled language really is the way to go. The only thing holding me back to PHP is that it's what I have learned to work with for some while now and the development is quite rapid. So, is PHP a thing of the past and should be put aside in web applications in favour of Ruby, for instance? Thanks

    - by varunp88
    Hi, We are using WiX to create a setup. The installation works fine, but during uninstallation an error says that the [FileName].msi is missing in C:\Windows\Installer and the setup starts rolling back. It is not reproduced in all the machines. It happens only in few machines. Could someone please give a solution to this ? What may be the reason that this happens only in 5 machines out of some 100 machines ? Thanks and Regards, Varun

  • A versioning workflow for multiple similar (but not identical) deployments

    - by rs77
    I'm currently employed at a small non-tech organisation and have been given the role of coding the organisations' website. While I have enjoyed the task and have learnt much with web dev I've encountered a few issues that I'm hoping someone will be able to help with me or at least point me in the right direction on. A little background: The site I work on has subdomains that each have their own separate WordPress installation on - as this has been the easiest "backend" admin panel for the type of user who will be responsible for updating content (etc). Within the organisation I work under the Marketing Manager (MM) and I code according to his style guide and wire frames. While we have been working with only one subdomain since the beginning of the year the project has been relatively simple and straightforward. However, lately the workflow is becoming a little more complicated as our original subdomain has been copied over to the other subdomains. Each of the new subdomains receives minor edits to their stylesheets (eg. different pictures for background, slightly different colours here and there, etc). The issue: At the moment managing all the different subdomains has been "bearable", but the straw that's braking the camel's back at the moment has been the slight reversions the MM has required now that the CEO has seen the final product. The problem I'm having with reversions in stylesheets is that the CEO will one week state that he likes change "X" and then as the MM and I continue to modify the site (to now "Z"), will another week state that he wants us to change "X" to "W" but keeping most of the changes made in "Y". What I'm looking for is something that allows for: tracking file changes reverting changes made (or reverting back to 'a' from 'e' but including changes 'b' & 'c') easily upload necessary files to their respective WP-theme installation Does anything out there come close to addressing these issues? If so, what? Thanks for any help! PS - I'm learning Git at the moment and it seems to do the "tracking file changes" quite nicely. Haven't learnt about the reverting changes bit yet, though. Maybe for my final point I'm thinking of creating a shell script to automatically upload the files to their folders. Does Git do this too though? Addendum (alexbbrown) I had a similar problem: I ran a custom version of mediawiki where I installed various extensions in the versioned core (with svn). Each of the extensions required an section in the confit file, but the confit file also needed local configuration for each of several deployments. I could have implemented it using includes, but they would not be versioned; and rebasing branches each time is a chore. +50 experience points for a good answer in git.

  • How to force a textField to become editable?

    - by Tzur Gazit
    I have a custom tableViewCell with a UITextLabel inside it. When the cell is first displayed, the place holder is shown and then disappears when the user types something in. What I want is to go back to the parent view, and then to the sub view again, and that the field will show the text that the user previously typed. If I set the text field, simply with setText, the textField is not editable. Any idea?

  • Proxy web service from wsdl

    - by Paul Knopf
    I am trying to create a proxy .asmx that will call another web service. The web service service I am trying to use only allows a certain domain, so I am creating a proxy web service on that domain that then calls the actual service. Me -- Client (with allowed IP) -- actual service and then back. I know how to create a proxy CLASS from a wsdl to communicate with the service, but how do I use wsdl to create another service (that spits the same wsdl)?

  • Can I host an ASP.NET webite outside of IIS?

    - by boraer
    Hi everybody, I need to write an ASP.NET application which must handle a very large number of transactions per second - as many as 5000 users may transact at the same time. I think I will use WCF in back to communicate with SQL server. But in front, can IIS handle 5000 users at the same time effectively, or is there any simple way to host my application outside of IIS?

  • Parsing timestamp with Python2.4

    - by jellybean
    I want to parse a timestamp from a log file that has been written via datetime.datetime.now().strftime('%Y%m%d%H%M%S') and then compute the number of seconds that have passed since this timestamp. I know I could do it with datetime.datetime.strptime to get back a datetime object and then compute a timedelta. Problem is, the strptime function has been introduced with Python 2.5 and I'm using Python2.4.4 (an upgrade is not possible in my context). Any easy way to do this?
