    I'm attempting to create an NSArray with a grouping of string literals, however I get the compile error "Initializer element is not constant". NSArray *currencies = [NSArray arrayWithObjects:@"Dollar", @"Euro", @"Pound", nil]; Could someone point out what I'm doing wrong, and possibly explain the error message?

  • Recoomend company to take care or webserver and wordpress management?

    - by javipas
    I'm interested in setting up a professional WordPress site but I'd like to explore the pssibilities to leave the management of the webserver and even WordPress' management to a company that guarantees great availability, performance of the site (load times, security) and even SEO. My site is currently running on other platform but I plan on a migration on the next 4 weeks. I've done this usually, but I'd like to focus on the content, so I don't have to mess with webserver/mysql/php configs in order to get nice performance. Is there some (maybe hosting) company that is dedicated to this? Would it be better to hire a sysadmin with experience in those matters?

  • plugging in a 3.3V 50pin laptop HDD to USB?

    - by barlop
    I have a 50pin laptop hard drive. 1.8" wide. This 50pin connector concerns me.. Even if I get an adaptor, How can I know which side of the connector takes the power? I don't want to plug it in the wrong way. And I don't have n adaptor.. Could people link me to adaptors too. but main question is, which side to plug it in when I get the adaptor. I want to be sure. I do not want to blow the hdd. For the 3.3V I have a plan. Connecting green and black and using the orange cable(3.3v) to feed power. I am not too worried about that bit. But as I said.. Main thing is I want to know which side is 3.3V hard drive is MK6006GAH

  • Scala println in a for loop

    - by random459
    The following Scala code does just what I expect it to - it prints each line of some_file.txt. import scala.io.Source val lines = Source.fromPath("some_file.txt").mkString for (line <- lines) print(line) If I use println instead of print, I expect to see some_file.txt printed out with double-spacing. Instead, the program prints a newline after every character of some_file.txt. Could someone explain this to me? I'm using Scala 2.8.0 Beta 1.

  • Is it possible to COMPLETELY replace the start menu?

    - by Subaru Tashiro
    I plan to make a replacement for the Windows 7 start menu, and I would like to know if that's even possible. I understand that the start menu is part of explorer.exe but I do not intend to replace explorer.exe. Is it possible to launch the replacement start menu by clicking the native start orb? Is it also possible to launch the replacement by pressing the Windows key or ctrl+esc ? Is the Windows key a macro for ctrl+esc ? or is it two different hotkeys that do the same thing? May I know if there is any software that do any one of these things?

    - by Sandbox
    I discovered [Theory] and [Datapoint] attributes in NUnit. I am not very sure about how should I use these. I think they can be used for data-driven testing and this has got me interested. There aren't many resources available on the same. Can someone explain to me how to use them or point me to resources? Thanks.

  • List View Selected Index Changed in a multi-selectable list view

    - by Anton Indrawan
    I have a windows form with a listview control. I set the MultiSelect property to true and I added a selected_index changed event. I get the event fired when I click the same index as the current selected index. My expectation is that I will not get the event fired. The strange thing is that the event fired 1 second after I click the index. I appreciate for any reply to explain why this is happening.

  • Visual Studio: Debuggin non localhost domain, locally

    - by Skawful
    I have an entry in my hosts file that points somesite.com to 127.0.0.1 (localhost) so that I can test certain aspects of my web app (i goto http://somesite.com in a browser to test). Can someone suggest a way to debug a setup like this (in visual studio) that does not include using http://localhost? I understand that this can most likely be done using remote debugger, if that is the best way can someone explain how thats setup (or a link to a good article).

  • Why is dereferencing a pointer called dereferencing?

    - by optician
    Why is dereferencing called dereferencing? I'm just learning pointers properly, and I'd like to know why dereferencing is called that. It confused me as it sounds like you are removing a reference, rather than going via the pointer to the destination. Can anyone explain why it is called this? To me something like destination or pointed_to_value would make more sense.

  • UnicodeDecodeError when redirecting to file

    - by zedoo
    Hi, I run this snippet twice, in the ubuntu terminal, (encoding set to utf-8) once with ./test.py and then with ./test.py >out.txt: uni = u"\u001A\u0BC3\u1451\U0001D10C" print uni Without redirection it prints garbage. With redirection I get a UnicodeDecodeError.

  • ATI Radeon Drivers works with which linux distribution and version? [closed]

    - by amit.codename13
    I have ATI Mobility Radeon HD 5850 graphics card. Almost every new linux distribution seems to have an issue with it, when i install the drivers. Working without utilizing the graphics card leaves me so unproductive. So i made a plan to use older versions of linux, any distribution suitable as a desktop distribution. The problems that i am facing are, 1) After installing drivers the system boots and hangs, 2) There are unusual lines over the screen 3) After upgrade system doesn't start properly(hangs the usual old way) The kind of answers i am looking for is, distribution X(the newer the version the better) doesn't have the above problem after installing drivers for ATI Mobility Radeon HD 5850 graphics card. UPDATE: The new drivers released by AMD seems to fix all the issues, although they are still beta

  • jQuery noob: change border color of element on hover of another element.

    - by Kyle Sevenoaks
    I'd try to explain what I mean, but there is an easier way: click here for jsfiddle example. Basically I want the border color of the div rfrsh_btn to change when productOptionsMenu is hovered over. I'm using jQuery with the .noConflict var because this site also uses Prototype. jQuery: var $j = jQuery.noConflict(); $j(".productOptionsMenu").hover( function () { $j(#rfrsh_btn).css({"border-color":"#85c222"}); }; ); Thanks :)

  • SIP Service to record all calls?

    - by TK Kocheran
    I read an article that I can't find at the moment which detailed a way to have Google Voice point to a SIP phone number which forwards to your phone in order to take advantage of the SIP service in order to Have all calls use a data connection = no usage of cell-phone plan minutes. Record each and every conversation.* I really want to be able to accomplish this, primarily issue number 2, as all of the phone recorder tools in the Android Market essentially don't work for my Nexus One. I figure that I have one of two options with this. I could 1) use an existing (hopefully free) service which will do this for me or 2) I could set up a SIP service at my home. to somehow forward calls through my home server which will record the calls as well as forward calls to my cell phone. Obviously, the path of least resistance is the one I'd like to go down. Can anyone help me out with this? * I do understand that the legality of this varies from state to state here in the US.

  • 64 bit Windows 7 + 32 bit windows XP dual boot?

    - by Mick
    I have purchased an i7 based PC pre-installed with 64 bit windows 7 (home premium). Unfortunately some third party 32 bit software that I need to use is not working properly (see stackoverflow.com for details). I am now torn between the plan of installing windows XP 32 bit or making it dual boot. Which option do you think will give me the least problems? And if the answer is dual boot, then can you point me to a good guide for how to do it, preferably a guide specifically for my two OS's created in this order (i.e. 7x64 first). EDIT: the performance of my 32bit programs is critical so am concerned about any kind of 32bit XP "emulation".

  • What happens when I instantiate class in Python?

    - by Konstantin
    Could you clarify some ideas behind Python classes and class instances? Consider this: class A(): name = 'A' a = A() a.name = 'B' # point 1 (instance of class A is used here) print a.name print A.name prints: B A if instead in point 1 I use class name, output is different: A.name = 'B' # point 1 (updated, class A itself is used here) prints: B B Even if classes in Python were some kind of prototype for class instances, I'd expect already created instances to remain intact, i.e. output like this: A B Can you explain what is actually going on?
