  • Need help with creating complex UITableView items (like the Settings app).

    - by Craig
    I hoping to create a custom Settings view, similar to the Settings application, but with more control over the UI and access to some settings (i need to lock some of the settings). Obvously, there are a variety of UI elements mixed in each row of application's UITableView. For example, the 'Airplane Mode' setting shows a UISwitch, while the 'Wi-Fi' setting has a text value adjacent to the disclosure symbol (''). Further complicating matters, is the grouping of these settings. I have some general questions about the approach I should take: Seems like i need to save the name of the setting, its current value, its grouping, and the type of UI element(s) needed to modify its value. i would like to make use [NSUserDefault standardUserDefaults], but not have these settings appear in the Settings application. I'm guessing that I will need to create my own settings-persistence class. is it better to build each one of these complex UI-element combinations in code or to create a series of custom views based on the UITableViewCell and load the appropriate one? i'm guessing the latter. some of the setting require that i load another view to select its value. assuming that the application is based on the Utility pattern, should the SettingsView manage the navigation stack, rather than having the app delegate do so? Thanks for your time and comments. Craig Buchanan

  • Advice needed- aweber form submission using curl?

    - by i need help
    Advice needed for backend form submission to aweber and get response. Scenario When customer signup at my form, I will 1. insert the customer details into my own database, 2. send them a welcome email from my system, 3. at the same time I want the email to be added into aweber (this should run in the background, so that customer no need to fill in details for second time) If I use the php curl call alone, is it a good solution? I want to submit form value to aweber, so that aweber add the new email into their system, and then response to my backend script? I have seen many versions outside, which may include: http://scripts.incutio.com/httpclient/ http://freshmeat.net/projects/curl_http_client/ http://snoopy.sourceforge.net/ Are they having any special benefit over the normal php curl call to pass in data?

  • Payment Processors - What do I need to know if I want to accept credit cards on my website?

    - by Michael Pryor
    This question talks about different payment processors and what they cost, but I'm looking for the answer to what do I need to do if I want to accept credit card payments? Assume I need to store credit card numbers for customers, so that the obvious solution of relying on the credit card processor to do the heavy lifting is not available. PCI Data Security, which is apparently the standard for storing credit card info, has a bunch of general requirements, but how does one implement them? And what about the vendors, like Visa, who have their own best practices? Do I need to have keyfob access to the machine? What about physically protecting it from hackers in the building? Or even what if someone got their hands on the backup files with the sql server data files on it? What about backups? Are there other physical copies of that data around? Tip: If you get a merchant account, you should negotiate that they charge you "interchange-plus" instead of tiered pricing. With tiered pricing, they will charge you different rates based on what type of Visa/MC is used -- ie. they charge you more for cards with big rewards attached to them. Interchange plus billing means you only pay the processor what Visa/MC charges them, plus a flat fee. (Amex and Discover charge their own rates directly to merchants, so this doesn't apply to those cards. You'll find Amex rates to be in the 3% range and Discover could be as low as 1%. Visa/MC is in the 2% range). This service is supposed to do the negotiation for you (I haven't used it, this is not an ad, and I'm not affiliated with the website, but this service is greatly needed.) This blog post gives a complete rundown of handling credit cards (specifically for the UK).

  • Which CMS do I need? Needs to be easy to post a certain kind of post

    - by Vian Esterhuizen
    Hi, I'm creating a site for a video store and it needs to be CMS. I'm doing this for free so I need to use a free CMS like Wordpress, Drupal or Joomla. Do I need a new CMS, a plugin or some PHP of my own? What I need: User accounts Categories Custom post Here's the site as it stands with WP: http://sundancevideo.ca. Right now an experimental site to try to work this out. What I've done now, is created a "Draft" that includes a template table with images and text and so on. The user would then have to copy everything, past into a new post and replace necessary. This really isn't working well. As you may notice by the condition of the posts. What I would prefer is if it was integrated into the WP UI. Like a field for "Description" and field for "Image" where they can upload the images as necessary. This would then generate post, with a table including all the information and images, for as many movies that were added in the UI. Please ask if I'm not being clear. Please help, any suggestions are welcome. Thank you, Vian

  • How much memory I would need for something like this?

    - by Vdas Dorls
    If I create social portal similar to Twitter (not exactly twitter, but similar in my country), how much space would I need for images? I guess with 100 gb of disk space it won't be enough, so could you please give me some information how much I would exactly need? And is there any suggestions how should I add the profile images? Is there any tactics from programming side, when I could save some space uploading and hosting images for profile users? I guess, each time user changes images, it would be good to delete the previous image, correctly? In additional, how much disk space would be needed for 1000000 user profiles, if we have like 15 default images, and part of the users won't upload their own images, but use some of the default ones. So 3 questions - How much disk space I would need to hold a good social portal? Is there any suggested way to deal with pictures with PHP to save disk space? How much disk space would be needed for 1000000 user profile, if we have like 15 default images and part of the users won't upload their own, but instead use one of the 15 default images?

  • Why do you need "extern C" for C++ callbacks to C functions?

    - by Artyom
    Hello, I find such examples in Boost code. namespace boost { namespace { extern "C" void *thread_proxy(void *f) { .... } } // anonymous void thread::thread_start(...) { ... pthread_create(something,0,&thread_proxy,something_else); ... } } // boost Why do you actually need this extern "C"? It is clear that thread_proxy function is private internal and I do not expect that it would be mangled as "thread_proxy" because I actually do not need it mangled at all. In fact in all my code that I had written and that runs on may platforms I never used extern "C" and this had worked as-as with normal functions. Why extern "C" is added? My problem is that extern "C" function pollute global name-space and they do not actually hidden as author expects. This is not duplicate! I'm not talking about mangling and external linkage. It is obvious in this code that external linkage is unwanted! Answer: Calling convention of C and C++ functions are not necessary the same, so you need to create one with C calling convention. See 7.5 (p4) of C++ standard.

  • Why we need apache Tomcat server to deploy any application. or what are the requirements to deploy any code or release?

    - by Shank_SCM
    I am asking very basic concept as I am new to build and release team. I am working with ant scripts to build and deploy the java code + working with TFS to deploy .net code. So my question is: What is apache tomcat and why we need it? Can't we deploy any piece of code or any application without apache tomcat? For windows, what framework we need to deploy(or same tomcat can be used for same)? Please make me understand the basic concept so that I can understand the deploy process or per-requisites of deploying process. what I know (to deploy) Just copy the tar file or zip file to any concerned dev environment and restart the server. Thats it. Please correct me if I am wrong.

  • What do I need to write a small game on Linux?

    - by Michas
    I want to make a simple game: 2d, single-player, without tons of animations and special effects. I am not interested in ready to use game engines, I want to learn to write some code in a quite universal language. I am using Linux (AMD64) and looking for something easy with nice library for games. I do not want to mix few languages, most of them are in fact fast enough themselves for my needs. Cross platform would be an advantage, however all I need is a good Linux support. I have been considering few solutions. Ruby + Language looks very nice. + I am going to learn Ruby. - I am afraid I can have problems with additional libraries. - This thread about game libraries for Ruby could be longer. SDL + C + It is used for games. + It is very easy to set up. + There is a lot of additional libraries. + It is cross-platform. - The solution is quite low level. - The language is sometimes quite hard to read. QT + C++ + It is very easy to set up. + The standard QT libraries supports everything I can possibly need. + It is cross-platform. + The documentation is good. - The compilation is slow. - The language looks horrible. - The size of standard QT libraries is too big to comprehend. Environment of web browser + I am going to learn something more about this environment. + It is somewhat used for games. + It is quite cross-platform. - It would be too much experimental. Java + It is used for games. + The standard Java libraries supports everything I can possibly need. + It is cross-platform. - It is quite hard to set up. - The size of standard Java libraries is too big to comprehend. - The source code in Java could look better. - I think I do not want to learn Java. Google Go + I am going to learn Google Go. - There is big problem with libraries. - The solution would be quite low level. Python + It looks some people do games in Python, according to this thread. + It looks there are probably more libraries than for Ruby. - The Ruby language looks better. - I think I do not want to learn Python. C++ + something else + It is used for games. + It would be probably cross-platform. + There is a lot of libraries. - I do not need C++ extensions over C. - Compilation could be slow, there are fast compilers for C, not for C++. Haskell + I am going to learn Haskell. - Many things about programming computer games looks too much imperative. - It looks I can have some problems with libraries. - Compilation (GHC) looks slow. There is probably something more to consider. Does anyone have experience in making small games for Linux in non mainstream solutions? Does anyone have an advice for me?

  • I need a piece software to use with my HP F4280 scanner.

    - by D Connors
    So, I got this printer/scanner about a year ago, and I'm really happy with it. The only thing is that I never really liked the HP scanning software that came with it. A few months ago I reformatted and reinstalled windows 7. Then, once I plugged in the printer, I noticed that windows recognized it automatically, and offered to install all the drivers by itself. So instead of manually installing the driver that came in the CD, I simply let windows automatically install it from its servers, and so far it's great. Instead of HP's scanning software (that really wasn't pleasing me), I got a very simplified interface that is more than enough for my ocasional scanning habits. Until today. Today I had to scan a bunch of old pictures for my father. And that simple interface felt like it was lacking quite a few features to make this repetitive task a little easier. And that's why I'm now looking for a good software to use for scanning. By "good" I mean anything well thought out, and specially anything that will make my life easier when repetitive-scanning. It doesn't need to have professional tweaking options, but having them is not a problem either. You guys got anything?

  • Need help with some IIS7 web.config compression settings.

    - by Pure.Krome
    Hi folks, I'm trying to configure my IIS7 compression settings in my web.config file. I'm trying to enable HTTP 1.0 requests to be gzip. MSDN has all the info about it here. Is it possible to have this config info in my own website's web.config file? Or do i need to set it at an application level? Currently, I have that code in my web.config... <system.webServer> <urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" /> <httpCompression cacheControlHeader="max-age=86400" noCompressionForHttp10="False" noCompressionForProxies="False" sendCacheHeaders="true" /> ... other stuff snipped ... </system.webServer> It's not working :( HTTP 1.1 requests are getting compressed, just not 1.0. That MSDN page above says that it can be used in :- Machine.config ApplicationHost.config Root application Web.config Application Web.config Directory Web.config So, can we set these settings on a per-website-basis, programatically in a web.config file? (this is an Application Web.config file...) What have i done wrong? cheers :) EDIT: I was asked how i know HTTP1.0 is not getting compressed. I'm using the Failed Request Tracing Rules, which reports back:- DYNAMIC_COMPRESSION_START DYNAMIC_COMPRESSION_NOT_SUCESS Reason: 3 Reason: NO_COMPRESSION_10 DYNAMIC_COMPRESSION_END

  • Can you transfer a Windows 7 XP-mode VHD to a new PC without the need for reactivation?

    - by Henk
    Hi. At the moment I am running Vista 32 bit and use VPC 2007 a lot. I have several W2000 VMs set up with complex software configurations. For me, one of the advantages of working with VPCs is that a VM can easily be copied to another PC (like a notebook). Also, when I move to a new PC, I can immediately work with my existing VMs without the need to reinstall all applications. I am thinking about buying a new pc with Windows 7 64 bit pro, and using the xp-mode VM that comes with Windows 7. The advantages would be support for more memory (so being able to run more VM's simultaneously) and having a licenced XP VM. I would like to know if you can transfer a VHD that is based on the xp-mode VHD to another machine without Activation issues. The other machine will of course, also be running W7. I would guess that this would not be a problem. However, I did read about a guy who had to reinstall his W7 because of a harddisk failure, and could not access his xp-mode VHD anymore because it demanded re-activation. Thanks. Henk.

  • OS X borked; need to backup outside of Time Machine

    - by rlbgator
    Quick Background: iMac G5 (the white one; 4 years old?) Running Leopard 10.5.something. Time Machine started failing on me; and every time I touch the Finder, things beachball like crazy. Booting from install disk then using Disk Utility to "Repair Disk" also fails. I'm left with the conclusion that I have a corrupt file somewhere important, that's (i) keeping TM from working and (ii) messing with basic functionality. I am not (yet) savvy enough in OS X to know what logs to look in, or how to decipher them - but 'corrupt file' seems to be the likely case, based on my readings of apple.com forum threads. So I think I need to backup, outside of Time Machine, then install fresh OS X on a new drive (or maybe SpinRite the current drive?). I'm able to put a (non-Time Machine) external USB drive on, so I dragged all 3 Users' folders to that... am I done backing up? Am I going to have a massive Permissions problem, trying to put things back together after a re-install? Thanks for reading.

  • pg_dump not working - do I need to change order of $PATH?

    I'm trying to set the $PATH to pick up the latest version of pg_dump as I'm currently getting a mismatch error while doing a migrate in my Rails app (I recently changed the schema type to SQL).

  • How can I take a one time full backup of a Windows Server without the need for a restore program?

    - by TheCleaner
    I have a Windows SBS server with about 500GB of data that I'm decommissioning but I'd like to take a final backup of the server and place it on an external USB drive. I already have multiple backups of the server on disk from the past but they are through Simpana Commvault. I'd like a backup that will simply copy the file structure, ACLs, timestamps, etc. as is to a NTFS volume on the external drive. This way if someone says "I need x file on the server you decommed" I can search the external drive real quick instead of firing up Commvault, cataloging, restore, etc. I know the built-in Windows backup is great, I just don't feel like running it for a restore job on this. I'd like an option where in the future it won't require a program to run a restore. Rather a simple mount of the drive will suffice. I believe I can use robocopy just fine, but I'm not sure if it will grab the Windows directory, system files, and full user profiles correctly even with the /ZB option. Options? Is Robocopy /E /ZB /COPYALL /DCOPY:DAT /MT:32 /R:5 /W:5 /LOG:copylog.log the way to go here?

  • Ubuntu server crashes; need help figuring how to figure out why

    - by neezer
    I have a 768 Slice at slicehost.com running Ubuntu Server 8.04.2 LTS (hardy) with a LAMP stack on it that periodically crashes, though why I am not sure. From what I can tell, there is a process that basically goes rogue and consumes all the memory on the slice, suffocating all the other programs running until the whole thing comes to a grinding halt, and I have to do a hard reboot of the slice to get it back up and running again. I can't detect any pattern for this (it seems to happen about once a month, more or less). Here's a screenshot of my console during the last crash: I would assume that a possible cause might a PHP script or an apache configuration rule that might cause the crash if triggered? How would I be able to find out which one is the offending one? I've checked and rechecked all my PHP scripts, and running them doesn't seem to trigger the crash. I've also been able to log on to my system during a crash and see what's running (with top), but I can't tell how the offending process was started, so I can't trace the root of the problem! I know my description is overly generic, but unfortunately my expertise in tracking down the source of these glitches is very limited. If you need any additional information about my system in order to help me figure this out, please let me know in the comments, and I will append it to the question. My only other lead as to the culprit here is Wordpress, which we have installed on this server. Here are the details: Wordpress 3.0.3 with the following plugins installed and activated: Addmarx - Bookmark/Share/Email Dropdown, Akismet, All in One SEO Pack, Animated Banners, Automatically publish highlights of any website, directly to your Blog, Broken Link Checker, CMS Dashboard, Collapsing Categories, Status Updater, SubHeading, Ultimate Google Analytics, VastSubCat, WP-CMS Post Control, and WP Super Cache

  • Why would I need a firewall if my server is well configured?

    - by Aitch
    I admin a handful of cloud-based (VPS) servers for the company I work for. The servers are minimal ubuntu installs that run bits of LAMP stacks / inbound data collection (rsync). The data is large but not personal, financial or anything like that (ie not that interesting) Clearly on here people are forever asking about configuring firewalls and such like. I use a bunch of approaches to secure the servers, for example (but not restricted to) ssh on non standard ports; no password typing, only known ssh keys from known ips for login etc https, and restricted shells (rssh) generally only from known keys/ips servers are minimal, up to date and patched regularly use things like rkhunter, cfengine, lynis denyhosts etc for monitoring I have extensive experience of unix sys admin. I'm confident I know what I'm doing in my setups. I configure /etc files. I have never felt a compelling need to install stuff like firewalls: iptables etc. Put aside for a moment the issues of physical security of the VPS. Q? I can't decide whether I am being naive or the incremental protection a fw might offer is worth the effort of learning / installing and the additional complexity (packages, config files, possible support etc) on the servers. To date (touch wood) I've never had any problems with security but I am not complacent about it either.

  • need some help figuring out clamav & monit monitoring error...unixsocket...

    - by Ronedog
    I need a bit of help figuring something out. First off, I'm not very well versed with FreeBSD servers, etc. but with some direction hopefully I can get this fixed. I'm using FreeBSD and installed Monit so I could monitor some of the processes that run tomcat, apache, mysql, sendmail, clamav. So far, I'm only successful in getting apache & mysql to be monitored. I'm getting this error for clamav in the log file for /var/log/monit.log 'clamavd' failed, cannot open a connection to UNIX[/usr/local/etc/rc.d/clamav-clamd] My config file for clamav in /etc/monitrc is: #################################################################### # CLAMAV Virus Checks #################################################################### check process clamavd with pidfile /var/run/clamav/clamd.pid group virus start program = "/usr/local/etc/rc.d/clamav-clamd start" stop program = "/usr/local/etc/rc.d/clamav-clamd stop" if failed unixsocket /usr/local/etc/rc.d/clamav-clamd then restart if 5 restarts within 5 cycles then timeout Honestly, I really don't know much of what's going on here. My host who helped me get the box set up basically installed clamav, but doesn't offer this kind of detail in supporting me, so I'm left to figure this stuff out on my own as I own the box, but they provide the isp service. Is there anyone who can help me troubleshoot this? Thanks for your help in advance.

  • Why do I need a managed switch and which one should I buy?

    - by ascanio1
    I bought a 2nd router and I want both routers to have direct WAN access to the modem. One of the 2 routers directs VOIP traffic to a telephone line port. This VOIP service is provided by the cable carrier which also leases the modem & the router. The cable company technician told me that this VOIP line uses IPv6 addressing and therefore I must employ an IPv6 capable/compliant Giga Hub/Switch or my telephone line won't work anymore. Pls advise me (brand/model) an IPv6 compliant, 2 port, switch to purchase. Pls educate me: By reading this forum I thought that hubs broadcast traffic to all ports, regardless of which input/output is being used and so, theoretically, they have nothing to do with IP. Correct? Same story for unmanaged switches, where the only difference is that these latter devices route traffic only to those ports which are detected to be in use. Correct? I also understood that unmanaged switches route traffic simply by detecting hardware use and not by selecting specific IP traffic. Correct? Finally, there are managed switches which DO select traffic based on IP and, therefore, only these managed switches are involved with IPv6... Why would my cable company explicitly tell me, over and over, that I must use an IPv6 compliant switch? Why would they need a managed switch instead of an unmanaged one? Thanks in advance for helping me understand!

  • I need to preserve a tape using symantec backup exec. I'm aving trouble doing so

    Please forgive me if this is the wrong stack exchange site. Please suggest which one I should post this to if it is. There's an automatic tape machine running in a remote location, with software (symantec backup exec 11d) Recently one of the servers being backed up had problems with its raid controller, so one of the drives has become invisible. I need to preserve the last good backup of that drive so I am trying to replace the tape with the most recent backup of that drive on it with one of the scratch tapes (blank tapes) present in the machine. I've tried the following... Associate the blank media with the media set in question (Wednesday) For the existing media (the tape with the data I want to keep) I click 'move to vault' and move it to the offline vault. I associate it with something other than 'Wednesday' (a media set called 'keep data infinitely...') I then do an inventory on that slot. The above steps I'm led to believe are supposed to put the fresh tape in the slot that had the tape I want to keep in it. But it just keeps showing up as containing the tape I want to keep after the inventory. (after refreshing the device tree) I am a complete newbie with this software. Can you tell me what I'm doing wrong, and/or tell me how to acheive my desired goal Edit: Just want to point out that I did try to get help directly from symantec with this, but having jumped through countless hoops to create an account and create a support ticket my progress was halted by requiring something called a 'tecnical contact id' at the final step with no explanation of what it is or how to get one.

  • what type of laptop do I need to run a amd64 or i386 VM?

    - by Frank Schwieterman
    I was running an amd64 build of Ubuntu on a VM on a Windows host which was also amd64. Later I found I could not run the same amd64 iso on my laptop, which is intel without hyper-V. I was confused I thought chipset mattered, but maybe it does not. When buying a PC or Apple, is there anything to check about the chipset to make sure it can run different types of VMs? In my case, I was trying to run ubuntu on a Thinkpad T520. Per answer below, I did need to enable some bios settings. I'm still having some issues. Running ubuntu on virtual box, when I try to use ubuntu-12.10-server-amd64.iso for the CD/DVD device to start a new VM, virtualbox complains "Failed to open the CD/DVD image . Could not get the storage format of the medium (VERR_NOT_SUPPORTED). When I try to use ubuntu-12.10-server-i386.iso the ISO is accepted, but then the VM complains "FATAL: No bootable medium found! System halted." I had been using an amd64 iso on my home PC which is amd64 and it works fine, which is why I suspected CPU mismatch was the problem at first. But it seems like I'm having issues, and maybe this superuser thread can be used to verify the cpu is irrelevant in this case.

  • What hardware would I need (approx) to run ESXi server?

    - by mr.b
    Hi, I am considering to purchase off-the-shelf commodity hardware in order to build server that will host virtual machines using ESXi server. Intended purpose for this server is NOT mission critical tasks. It will have to run perhaps 20-50 Windows XP/Vista/7 virtual machines (in total, but closer to 20 figure). Each guest would have to have 1-2 GB of ram, and probably two-three times more disk space than guest OS needs with clean install and all updates applied (that would be around 6-8 GB for XP, and i believe closer to 10-15 for win7). Those guests will act as a test ground for a new product that is network management software, thus guests will idle most of their time once initially loaded, but if I give them some task to complete, they should be able to perform reasonably well. Now, from what I have learned... CPU is usually not much of an issue (6 cores would do it), memory should not be lacking, but doesn't have to be sum of all guests, because of overcommitment... That leads me to IO, which is, as it seems, the bottleneck. Since I have very little experience with ESXi (and ESX, too) server, I'd like to ask: How much memory could I save by overcommitment, and how does it affect performance? Is 6-core cpu enough to run above described system? Would it be possible to run entire server off two (or even one) SSD drives (to host system virtual disks, with few additional HDDs (2-3) in RAID 0 to be used as secondary storage? I read somewhere that ESXi allows having something like "master image", essentially virtual machine that is "deployed" many times, so that disk space can be saved by having only differences stored by specific guests, instead of copying around whole virtual disks. Is this true, and how can this help me? Are there any other things I need to take into consideration when building this off-the-shelf solution? I should probably mention here that I'm fully aware of issues like SPOF regarding power supply, raid 0, etc, but since it's only a testing ground and not a production system, it's not so important for me. Thanks, B.
