  • Is the method addSubview of NSView inherently slow? (Cocoa OSX)

    - by Michael Minerva
    I am trying to speed my gui that loads very slow slow when I am loading a large project (the gui is a representation of groups and sub groups and is made up of many views). During this process I was looking at how long certain code segments take to execute and I have found that a call to addsubview is taking between 10 and 20 milliseconds most of the time. The subview I was looking at is a disclosure button. I am wondering if this method is just inherently slow or is their some other factor at work here? Is the time it takes to add the subview dependent on the complexity of the subview or is that not a factor? Also, is there some other method that can be used to add a subview that might be faster?

  • Looking for a good C++/.net

    - by Michael Minerva
    I have recently started to feel that I need to greatly improve my C++ skills especially in the realm of .net. I graduated from a good four year university with a degree in computer science about 9 months ago and I have since been doing full time contract work for a small software company in my local area. Most of my work has been done using Java/lisp/cocoa/XML and before that most of my programming in my senior year was in java/C#. I did a decent amount of C++ in my Sophomore year and in my free time before that but I feel that my general knowledge of C++/.net is very lacking for the opportunities that are now coming my way. Can anyone recommend a good book that could help me get up too speed? I feel I do not need a very basic introduction to C++ but something that covers the fundamentals of .net would be good for me. So basically what I need is a book or books that would be good for a .net novice and a C++ developer who is just beyond novice. Also, a book that would help bein an interview by giving me a conversional understanding of C++ would be great. Thanks a lot!.

  • Trouble shooting openGL text textures not showing up correctly cross platform

    - by Michael Minerva
    I have been tasked with solving a problem that is outside of my domain of knowledge and I was hoping I could get some troubleshooting advice from someone more experienced with openGL (I have very little experience with openGL). We are working on a cross platform application that is implemented in a common lisp implementation called ccl. In this application we have a need to display some 3D objects that display text. On the mac, all of the text displays fine but on the PC instead of displaying the text it displays some other texture. At first I thought that maybe the wrong texture was just being referenced so I tried changing the texture number but none of the textures in the list appeared to be the text (or if it was the texture was distorted and did not look like text). I know this problem is very vague and I am not looking for someone to post a solution, but I was wondering if people could suggest places I might look to try and get a handle on this issue.

  • Preserving the GLBlendFunc

    - by Michael Minerva
    I need to preserve the current GlBlendFunc so can restore it after I do some work. It seems that this is not one of the attributes that can be saved with GLPushAttrib, is there some other similar method I can use to preserve the state?

  • Is there anyway to "probe" a method in common lisp

    - by Michael Minerva
    My application allows the user to create their own methods indirectly and I later need to refer to these methods. I am wondering if there is a way (for error checking purposes) to test if a method exists without trying to execute it. If I just try and call the method and it doesn't exist this will crash my application.

  • Does strokeRect: of NSBezierPath always draw a transparent rect? (Cocoa OSX)

    - by Michael Minerva
    I am trying to make a custom selection box for an image view I created and I am trying to use strokeRect: from NSBezierPath but it always seems to be transparent. Called the method set to set the color the blackColor and then also tried using olorWithDeviceRed:green:blue:alpha: but no matter what I have tried the rectangle created always seems to be transparent. Is there a better method to use to draw an empty rectangle?

  • What do you use to loadbalance IPv6 services?

    - by Michael Renner
    Hi, the current Linux software environment for IPv6 load balancing looks a bit grim. IPVS has rudimentary support for IPv6 but it's far from complete. NAT for IPv6 seems to be a no-go. Are there any other projects which aim for this goal? Does the IPv6 support in other OS look better? Are there any commercial products which have been successfully used in production environments with non-trivial load patterns? Or is it just that the time for IPv6 hasn't come... yet? ;) best regards, Michael

  • Windows 7 Locking up Randomly

    - by Michael Moore
    I've got a Windows 7 machine that is locking up randomly. It can be in the first thirty seconds, or it can be hours later. There is nothing specific I can find that is running when it happens. When it locks, the screen doesn't change, but nothing moves. The waiting icon stops, the mouse stops, keyboard doesn't work, etc. I've even tried the crash on ctrl-scrl registry hack, and it won't even dump the kernel. I've run hardware diagnostics on the RAM and it doesn't find any problems. I would think it is a hardware issue, but on this exact same machine, I can run 64 Bit Ubuntu and it has zero problems. I've even tried reinstalling Windows7 from scratch, and it still happens. Anyone have any ideas? Any good diagnostic tools to recommend? Thanks! Michael

  • USB Flash drive corrupt files - Help needed

    - by Michael
    I have a 16gb usb flash drive with 8gb worth of data that I can't afford to lose. When I inserted it into my pc, inside the folder that I was storing the data I saw unintelligible characters and nothing in there would open. I ran, windows scandisk and the files (unfortunately) disappeared. I can see that the drive's space still appears to be taken up with data, about 8gb. What should I do to recover it? Is it possible? Thanks in advance... Michael

  • Secure copy in Linux

    - by Michael
    Hi all, I wanna simpy exchange 3 directories to a collegue's home directory (I dont have write access to that one) from my home directory, probably using secure copy if possible. I am not good with Linux command line, so I am not sure how to do that and I would very much appreciate it if somebody could help me a bit out with this. I guess it should look something like that scp -r /home/user1/directoy1 /home/user2/directoy1 scp -r /home/user1/directoy2 /home/user2/directoy2 scp -r /home/user1/directoy3 /home/user2/directoy3 Do I need to specify the login name of my collegue so that the files can be copied when he enters his password? Thanks for your help, Michael

  • Virtual hosting in Varnish with individual vcl files for configuration

    - by Michael Sørensen
    I wish to use varnish to put in front of an apache and a tomcat on the same server. Depending on the ip requested, it goes to a different backend. This works. Now for most of the sites the default varnish logic will work just fine. However for some specific sites I wish to use custom VCL code. I can test for host name and include config files for the specific domains, but this only works inside the individual methods recv etc. Is there a way to include a complete set of instructions, in one file, per domain, without having to manage separate files for subdomain_recv, subdomain_fetch etc? And preferably without running seperate instances of varnish. When I try to include a file on the "root level" of default.vcl, I get a compilation error. Best regards, Michael

  • jQuery jFlow plugin. How can I have more than one on a single page?

    - by Michael
    Hi, I'm using a very lovely and simple plugin called jFlow that gives me a basic content slider etc. However, I can see no documentation or help on how to get two (or more) on one page at the same time working seperately from one another. At the moment, if I set two up, they almost combine as one, despite having a different configuration from one another. Any help would be great, thanks. Michael.

    First post here. I have a asp/vb6 web app that logs in a user I want to encrypt the users identity field and pass(querystring) it to a asp.net app and then decrypt it to do a db lookup. I've google'd it of course and found rot13, not secure enough. I've also found some hits on MD5 / RC4 but did not find any good examples of encrypt / decrypt. Thanks, Michael
