  • Objective C iPhone performance issue

    - by Asad Khan
    Ok guys I am developing an iPhone app I have a Model class which follows a Singleton design pattern. Now I have an NSArray in it which is initialized to around some 1000 NSStrings in the init method. Now I need to use this data in some view controller. so I import Model.h, I create an array of NSString objects in view controller & set the data to it. But now the problem is that now I have 2000 NSStrings currently allocated, which I believe is not a good thing on iPhone due to memory considerations. releasing model object wont help because I've overrided release method to release nothing according to the pattern & I cannot change the design now because now a lot of code works on the assumption of model being a singleton. & in future maybe the initial NSStrings may grow to 2000 or even more & then I'll have 4000 NSStrings allocated at one time .... I am a little confused on how to go about it any suggestions

  • How are classes more secure than structures ?

    - by Asad Hanif
    Structure's member are public by default ans class's members are private by default. We can access private data members through a proper channel (using member function). If we have access to member functions we can read/write data in private data member, so how it is secure...we are accessing it and we are changing data too.....

    - by Malik Hassan
    Something happened to my keyboard and or mouse controls. I have a Logitech T-BB18 trackwheel and an hp NY418AA Keyboard.

  • Having Hotlink Protectin problem in nginx

    - by Ayaz Malik
    Hello, i am having image hotlink protection problem in my nginx need help. i have a huge issue of my site's images being submited to social networks like stumbleupon with direct link ... xxxxx.jpg which some times get huge traffic and increases cpu usage plus bandwidth usage. what i am trying to do is block direct access to image from other refrers and hotlink protection. Here is the code from my vhost.conf server { access_log off; error_log logs/vhost-error_log warn; listen 80; server_name mydomain.com www.mydomain.com; # uncomment location below to make nginx serve static files instead of Apache # NOTE this will cause issues with bandwidth accounting as files wont be logged location ~* \.(gif|jpg|jpeg|png|wmv|avi|mpg|mpeg|mp4|htm|html|js|css)$ { root /home/username/public_html; expires 1d; } root /home/mydomain/public_html; } location / { client_max_body_size 10m; client_body_buffer_size 128k; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; # you can increase proxy_buffers here to suppress "an upstream response # is buffered to a temporary file" warning proxy_buffers 16 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_connect_timeout 30s; proxy_redirect http://www.mydomain.com:81 http://www.mydomain.com; proxy_redirect http://mydomain.com:81 http://mydomain.com; proxy_pass http://ip_address/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; expires 24h; } } So for hotlink protection i added this code : location ~* (\.jpg|\.png|\.gif|\.jpeg)$ { valid_referers blocked www.mydomain.com mydomain.com; if ($invalid_referer) { return 403; } This is how the current nginx code for this domain looks like but didn't worked: server { access_log off; error_log logs/vhost-error_log warn; listen 80; server_name mydomain.com www.mydomain.com; # uncomment location below to make nginx serve static files instead of Apache # NOTE this will cause issues with bandwidth accounting as files wont be logged location ~* \.(gif|jpg|jpeg|png|wmv|avi|mpg|mpeg|mp4|htm|html|js|css)$ { root /home/username/public_html; expires 1d; } root /home/mydomain/public_html; } location ~* (\.jpg|\.png|\.gif|\.jpeg)$ { valid_referers blocked www.mydomain.com mydomain.com; if ($invalid_referer) { return 403; } location / { client_max_body_size 10m; client_body_buffer_size 128k; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; # you can increase proxy_buffers here to suppress "an upstream response # is buffered to a temporary file" warning proxy_buffers 16 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; proxy_connect_timeout 30s; proxy_redirect http://www.mydomain.com:81 http://www.mydomain.com; proxy_redirect http://mydomain.com:81 http://mydomain.com; proxy_pass http://ip_address/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; expires 24h; } } Thank you in advance :) cheers

  • Wastage of resources in Virtualization

    - by Sabeen Malik
    I have asked this question on SO, but was suggested that i ask it here on SF, so here it goes. http://stackoverflow.com/questions/3010753/wastage-of-resources-in-virtualization I am not sure if this is the right place to ask the question. However i hope it is. When looking for a VPS earlier today, I was trying to understand how each container would work in the background. Keeping in mind the fact that the operating system uses most of the memory and power on a system, wouldn't having multiple operating systems in the same machine mean more wastage of resources. For instance if i was running centOS on a dedicated box and it was running lets say 20 background OS level processes. Then i go and install a virtualization platform and install 5 more centOS virtual machines in the same system which are exactly the same as the host operating system. Doesn't this mean duplication of those 20 processes 6 times? So internally the context switching is happening between 120 processes instead of 20? Further Notes: Here is an example of what i am thinking: I have a master-slave configuration for a long running, cpu + memory intensive process, which can be distributed to 4 machines. Lets say when the process runs on these 4 machines with lets say 1 Gh CPU and 1 Gig RAM, i get 400 results per hour from the cluster (assuming 100 results from one machine) . Now i get a bigger machine ( lets say 4Gh and 4 Gig RAM), have 4 virtual hosts on it with 1 Gz CPU and 1 Gig RAM. Will this configuration give me the same 4 results per hour from these 4 virtual hosts?

  • Adding CNAME entry to nginx for cdn rewrite

    - by Ayaz Malik
    I am using apache + nginx (for serving static content) and just bought a CDN. I have added a CNAME entry to my CDN URL, which should be cdn.example.com and pointing to the original cdn url. xxx.netdna-cdn.com/ But probably because of my nginx vhost file when I run cdn.example.com, it opens the first server entry site in my vhost file. I have multiple sites in my server. I have added CNAME from CPanel DNS editor as well. No luck, so I think I need to add something in the vhost.conf.

  • Slow upload, fast download on Windows 7 64bit system

    - by Malik
    I've got a weird problem in the download speeds on my desktop PC (Windows 7 Home Premium 64bit) are consistently fast (approx. 400kB/s) but uploads are very slow (around 6-10kB/s). This has been going on for the last 3 weeks or so. I am a very competent user and troubleshooter, and have searched online for 2 weeks for a solution, to no avail. Part of the problem is that internet is provided by WiFi by my landlord and I have no access to the router (BT Home Hub router) although I know for sure he wouldn't have the first idea on how to restrict my usage :) (rules that out) Anyway, I've tried: - various drivers (my Wifi 'card' is TP-link TL-WN851N, and I've tried TP-link + Atheros + Qualcomm Atheross drivers, suggested by Microsoft) - various tweaks to network parameters (e.g. as suggested by SpeedOptimser) - various tweaks to Windows 7 services (e.g. disabling/manual-ing unecessary services) - raising and lowering head onto a reasonably firm surface at moderate frequency (jk :D) None of the above have helped, and I'm officialy asking for help now!! Thanks for your time and effort in advance!

  • Computer crashes twice/thrice before booting into windows

    - by Adil Malik
    I need help. i built a PC, and it behaves very strangely. When i press the power button, the lights come on, fan maxes out, HDD spins, bios shows up etc and then it immediately crashes (powers down) before booting into windows. Then it powers on automatically and this time boots correctly. Sometimes there is just one failed boot and sometimes it takes 2 such boots to correctly start the computer. This unexpected shutdown never happens once it has booted in windows, just between the windows logo and bios menu. Any ideas?

  • Split string on non-alphanumerics in PHP? Is it possible with php's native function?

    - by Jehanzeb.Malik
    I was trying to split a string on non-alphanumeric characters or simple put I want to split words. The approach that immediately came to my mind is to use regular expressions. Example: $string = 'php_php-php php'; $splitArr = preg_split('/[^a-z0-9]/i', $string); But there are two problems that I see with this approach. It is not a native php function, and is totally dependent on the PCRE Library running on server. An equally important problem is that what if I have punctuation in a word Example: $string = 'U.S.A-men's-vote'; $splitArr = preg_split('/[^a-z0-9]/i', $string); Now this will spilt the string as [{U}{S}{A}{men}{s}{vote}] But I want it as [{U.S.A}{men's}{vote}] So my question is that: How can we split them according to words? Is there a possibility to do it with php native function or in some other way where we are not dependent? Regards

  • does copyWithZone on an NSArray call copyWithZone on its elements too?

    - by malik
    Hi, here's the scenario, I have this array of Person objects. copyWithZone is implemented on Person and works as expected. I have an array of Person objects, however when I create a copy of the array and modify things in original array (change attributes of a Person) it chances the copy as well. So my best guess is that when I call copyWithZone on NSArray, it does not call it on its elements. Please confirm.
