  • CADisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • Website is live but ping times out

    - by infinity
    I have a client's website that is running on GoDaddy hosting and started behaving very strange recently. The site is up and running but when I try to ping it I get time out. The problem is PayPal doesn't work also Google Webmaster reported the site is down. The client spoke with support and they said there is no firewall or any other traffic filter on their side. The site itself is PHP. Any ideas are welcome. I've tried to send test IPN from PayPal to the payment URL and got: IPN delivery failed. Unable to connect to the specified URL. Please verify the URL and try again. Which makes me think that the website/server is inaccessible in some specific cases. The site URL is http://www.flavourly.com P.S.: I tried to ping it from different machines, ISPs and OS

  • On saving a new record an associated id changes to 9 figure number

    - by Dave
    Hi, I have a table of venues, with each venue belonging to an area and a type. I recently dropped the table and added to it some addressline fields. I have re-migrated it but now the area_id field saves as a random? 9 figure number. Both the area_id and venuetype_id integers are created in the same way from the create new form and the venuetype_id saves as normal but not the area_id. Can anyone offer any help? whats shown in the console => [#<Venue id: 4, name: "sdf", addressline1: "", addressline2: "", addressline3 : "", addressline4: "", icontoppx: 234, iconleftpx: 234, area_id: 946717224, ven uetype_id: 8, created_at: "2011-03-17", updated_at: "2011-03-17 23:33:53">] irb(main):030:0> the area_id should be 8 in the above example. The area and venuetype id's are slected from dropdown boxes on the new venue form. new form <%= form_for @venue do |f| %> <p>name: <br> <%= f.text_field :name %></p> <p>top: <br> <%= f.text_field :icontoppx %></p> <p>left: <br> <%= f.text_field :iconleftpx %></p> <p>addressline1: <br> <%= f.text_field :addressline1 %></p> <p>addressline2: <br> <%= f.text_field :addressline2 %></p> <p>addressline3: <br> <%= f.text_field :addressline3 %></p> <p>addressline4: <br> <%= f.text_field :addressline4 %></p> <p>area: <br> <%= f.collection_select(:area_id, Area.all, :id, :name) %></p> <p>venuetype: <br> <%= f.collection_select(:venuetype_id, Venuetype.all, :id, :name) %></p> <br><br> <div class="button"><%= submit_tag %></div> <% end %> Areas table class CreateAreas < ActiveRecord::Migration def self.up create_table :areas do |t| t.string :name t.timestamps end end def self.down drop_table :areas end end Thanks very much for any help!

  • Best practices for FQDN for standalone domain (is a two part domain.tld okay?)

    - by birchbark
    I've searched quite a bit and can't seem to find a straight, modern answer on this. If I am hosting a domain, say, mydomain.com, on a machine which is going to solely be used for that domain, and there are no subdomains, is there a real, practical reason besides compliance to create an arbitrary hostname (i.e. myhost) just in order to have a three-part FQDN (myhost.mydomain.com) to satisfy some sort of RFC or convention that's expected. This seems to make a lot of undue complexities from my perspective, and I'm not sure if there's an advantage to this or if it's just a hold-over from a time where all web resources came from a subdomains such as www and ftp which may need to scale to separate machines. I don't use www on my domain, either, which is ill-advised for all I know from an administrators perspective (though removing it is the norm from a designer's perspective)...

  • Can I convert my database/script to UTF-8 ?

    - by Mohannad Otaibi
    How can I convert a database to support UTF-8 and convert it's old data from what ever encoding they're in to UTF-8 ? Extra Info: I'm running a server which has many websites on it, and one of them is running WHMCS (php script to manage hosting clients). WHMCS has an iPhone application where i can browse it through iPhone, the problem is that this application will only run if everything in my website is in UTF-8 encoding. I was using windows-1256 as encoding in my script's settings, and i tried changing that in some point of time to UTF-8 for a while then changed it back to windows-1256 so, the data in the database are some inserted using UTF standards and most of them are windows-1256 If someone could clear the picture for me, Do I need to convert every database on the server or just one DB ? what should I change? If i had to do that manually, I'll do it but I need some expert advise.

  • Mac terminal: Resource temporarily unavailable

    - by user167108
    I'm getting an error message in the Mac Terminal when I try to run several different processes. I did some googling and looking on this site, and found out that it might be related to having too many processes running at one time. However, I'm getting these error messages when I only have a few windows open (much fewer than I was accustomed to having). Looking in activity Monitor, my %User number is at around 25%, and the %System number is around 15%. In the past, I have had both much much higher (until the people at the Apple store told me to keep an eye on it). So with these numbers lower now, what explains the Resource temporarily unavailable error message? heroku (cloud hosting) console -bash: fork: Resource temporarily unavailable -bash-3.2$ upon opening new window in the terminal sh: fork: Resource temporarily unavailable sh: fork: Resource temporarily unavailable trying to run -bash: fork: Resource temporarily unavailable

  • Too Many ESTABLISHED connection from a single IP address in Apache

    - by ananthan
    netstat -ntp |grep 80 shows too many ESTABLISHED connection from single IP address. Around 300 of them and it is not an attack and user is using a 2G connection to access Apache. This is the case with other 2G connections also. As a result of this Apache is running out of children. Earlier it was showing too many close_wait and after enabling tcp_tw_reuse and tcp_tw-recycle there is not much close_wait but the number of ESTABLISHED connections increased. We are using Ubuntu 11.04 having 48 GB ram keepalive On keepalive timeout 10 max clients 800 max-request-perchild 4000 timeout 300 I have set syn_ack to 1 and syn_retries to 2. On wifi there is no such issue. Connections are closing properly, but with 2G connections Apache is running out of children and too many ESTABLISHED connection. also i have tried setting timeout from default 300 to 30,but since our project is image hosting for mobile phones,clients couldn't upload images properly as they are getting frequent time out.Also there were a lot of 408 messages so changed it to the default 300

  • Multiple SSL domains on the same IP address and same port?

    - by John
    This is a Canonical Question about Hosting multiple SSL websites on the same IP. I was under the impression that each SSL Certificate required it's own unique IP Address/Port combination. But the answer to a previous question I posted is at odds with this claim. Using information from that Question, I was able to get multiple SSL certificates to work on the same IP address and on port 443. I am very confused as to why this works given the assumption above and reinforced by others that each SSL domain website on the same server requires its own IP/Port. I am suspicious that I did something wrong. Can multiple SSL Certificates be used this way?

  • How to enable a Web portal-based enterprise platform on different domains and hosts without customization

    - by S.Jalali
    I work at Coscend, a cloud and communications software product company. We have built a Web portal-based collaboration platform that we would like to host on five different Windows- and Linux-based servers in different hosting environments that run Web servers. Each of these Windows and Linux servers have a different host name and domain name (and IP address). Out team would appreciate your guidance on: (1) Is there a way to implement this Web portal-based platform on these Linux servers without customizing the host name, domain name and IP address for each individual instance? (2) Is there a way to create some variables using JavaScript for host name and domain name and call them from the different implementations? (3) Can these JavaScript modules be made portable and re-usable object modules for different environments and instances? The portal is written in JavaScript that is embedded in HTML5 and padded with CSS3. Other technologies include Flash, Flex. Databases used are PostgreSQL and MySQL.

  • Managing client passwords

    - by HurkNburkS
    I am just starting up a small website development business and one of the issues I am having is remembering passwords and account information for clients hosting, cpanel, ftp accounts etc. I was wondering what is the most suitable system / industry standard for controlling such information? Pretty marginal on the close there... I read the FAQ and I felt list this could be a common issue for webmasters, its defiantly not a coding questions so stackoverflow is out of the question and its not a broad question its focused on one particular aspect of being a webmaster.

  • Best server for mailing application [closed]

    - by Cyber Junkie
    My application is similar to a reminder service that reminds users of events that they scheduled. I'm sending emails to users through a PHP script. I'm not sending one email to multiple recipients. Each recipient receives a different message. I plan to use cron jobs every minute and expect the application to send roughly 200 individual emails in 1 hour (for a small user base that may grow). I don't have hosting experience with this type of application. I plan to start on a shared host and move up in the future to vps or dedicated. Most shared hosts that I looked into allow 50-100 emails per hour with delays between mailings. Please kindly inform me what I should look for in web hosts for this kind of application.

  • Why does this crash: stringByAppendingFormat

    - by Emil
    Hey. My code crashes at this function (at the stringByAppendingFormat: with error objc_msgSend() selector name: stringByAppendingFormat). This is that line: // imagesPath = ...iPhone Simulator/4.0/Applications/NUMBERS/Documents/images UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingFormat:@"/%d.png", [[self.postsArrayID objectAtIndex:row] intValue]]]; Could it have something to do with the retaining of objects? Thanks :)

  • How do Perl FIRSTKEY and NEXTKEY work

    - by mmccoo
    Tie::Hash has these: sub FIRSTKEY { my $a = scalar keys %{$_[0]}; each %{$_[0]} } sub NEXTKEY { each %{$_[0]} } NEXTKEY takes two arguments, one of which is the last key but that arg is never referenced? The various Tie docs don't shed any light on this other than this in perltie: my $a = keys %{$self->{LIST}}; # reset each() iterator looking at the doc for each doesn't add to this. What's going on?
