• iPhone application build fails with "dyld: Library not loaded: /System/[...]" error? Why?

  - by Andrew J. Brehm

  For my own reasons and not for the app store I am referencing the Apple private framework Apple80211 in an iPhone app. I got the framework from an earlier version of the iPhone SDK. I added the "existing framework", verified that that absolute path to the framework is /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/PrivateFrameworks/Apple80211.framework and tried to build the app. But the build (to device) fails with the error dyld: Library not loaded: /System/Library/PrivateFrameworks/Apple80211.framework/Apple80211 Referenced from: /var/mobile/Applications/3691587D-87AF-44EA-A505-F73D17F39B3B/iWire2.app/iWire2 Reason: image not found I cannot figure out why Xcode would look for the library in a /System path (instead of using the path given in the frameworks list) or how to change that behaviour. I tried the tricks I found here and elsewhere for similar (and identical) sitiations: Delete the myusername.* files in the xcodeproj bundle Delete the build directory Clean all targets Start new project Result is always the same. How can I add this (or a) framework to an iPhone project AND get Xcode to at least look at the library located where I point to rather than a location in /System?

• Data structure for unrooted trees

  - by Esmond

  I'm having problems figuring out how to build an unrooted tree with weighted edges and what data structure to store such a tree. An example of an unrooted tree would be like the one here: http://www.bio.davidson.edu/courses/GENOMICS/seq/unrooted.gif The problem i am having is the leaves would only have 1 link to the internal nodes and the internal nodes would have 3 links(the internal nodes would have 2 children and a link to another internal node). Do i have to distinguish between the 2 different kinds of nodes or can i have one class having the function of both types of nodes?

• Need help specifying a ending while condition

  - by johnthexiii

  I have written a Python script to download all of the xkcd comic images. The only problem is I can't tell it to stop when it gets to the last one... Here is what I have so far. import re, mechanize from urllib import urlretrieve from BeautifulSoup import BeautifulSoup as bs baseUrl = "http://xkcd.com/1/" #Specify the first comic page br = mechanize.Browser() #Create a browser response = br.open(baseUrl) #Create an initial response x = 1 #Assign an initial file name while (SomeCondition): soup = bs(response.get_data()) #Create an instance of bs that contains the response data img = soup.findAll('img')[1] #Get the online file path of the image localFile = "C:\\Comics\\xkcd\\" + str(x) + ".jpg" #Come up with a local file name urlretrieve(img["src"], localFile) #Download the image file response = br.follow_link(text = "Next >") #Store the response of the next button x += 1 #Increase x by 1 print "All xkcd comics downloaded" #Let the user know the images have been downloaded Initially what I had was something like while br.follow_link(text = "Next >") != br.follow_link(text = ">|"): but by doing this I actually send skip to the last page before the script has a chance to perform the intended purpose.

• what mysql table structure is better

  - by Sergey

  I have very complicated search algorithm on my site, so i decided to make a table with cache or maybe all possible results. I wanna ask what structure would be better, or maybe not the one of them? (mySQL) 1) word VARCHAR, results TEXT or BLOB where i'll store ids of found objects (for example 6 chars for each id) 2) word VARCHAR, result INT, but words are not unique now i think i'll have about 200 000 rows in 1) with 1000-10000 ids each row or 200 000 000+ rows in 2) First way takes more storage memory but i think it would be much faster to find 1 unique row among 200 000, than 1000 rows among 200 mln non unique rows i think about index on word column and no sphinx. So that do YOU think? p.s. as always, sorry for my english if it's not very good.

• How do I include a newline in a text message sent as email from an ASP.Net application?

  - by Tim Goodman

  I have an ASP.Net Application that sends text messages to mobile phones. It does this by sending an email. For instance, if your phone number is 555-555-5555 and your wireless carrier is Verizon, you can send an email to [email protected] and it will show up as a text message. I want to be able to include a newline in the body of the message. How do I do this? Also please note that my ASP.Net program gets the message from a database (MS SQL Server) so what I really need to know is what characters to include in the message body when I store it in my database. I already tried \n but it just showed up in the text message as \n

• How to deserialize JSON text into a date type using Windows 8 JSON.parse?

  - by canderso

  I'm building a Windows 8 Metro app (aka "Modern UI Style" or "Windows Store app") in HTML5/JavaScript consuming JSON Web Services and I'm bumping into the following issue: in which format should my JSON Web Services serialize dates for the Windows 8 Metro JSON.parse method to deserialize those in a date type? I tried: sending dates using the ISO-8601 format, (JSON.parse returns a string), sending dates such as "/Date(1198908717056)/" as explained here (same result). I'm starting to doubt that Windows 8's JSON.parse method supports dates as even when parsing the output of its own JSON.stringify method does not return a date type. Example: var d = new Date(); // => a new date var str = JSON.stringify(d); // str is a string => "\"2012-07-10T14:44:00.000Z\"" var date2 = JSON.parse(str); // date2 is a string => "2012-07-10T14:44:00.000Z"

• How to find (or generate) thousands of company names for test/demo purposes

  - by schefdev

  Ok, so this is rightfully a testing question more than a development question, but the two should go hand in hand :) So, I've got a system I'm building which includes business contact information. Pretty common no doubt. My test/demo database currently has randomly generated individual's names loaded (thanks to a handy IRS spreadsheet I found). This has worked great for internal testing and review purposes, but it looks really odd when shown to prospective customers. So.... Does anyone know where I can grab or find a listing of thousands of business names (address information too would be nice)? I've tried various online public information sources (e.g. EDGAR, and county based property records searches), but these all require me to manually stitch together the results in blocks of 50 names or so at a time. I could do this, but was really hoping for a search service or data store out there that had this type of information readily searchable and retrievable in very large batches. Thanks!

• Where are Wireless Profiles stored in Ubuntu [closed]

  - by LonnieBest

  Where does Ubuntu store profiles that allow it to remember the credentials to private wireless networks that it has previously authenticate to and used? I just replaced my Uncle's hard drive with a new one and installed Ubuntu 10.04 on it (he had Ubuntu 9.10 on his old hard drive. He is at my house right now, and I want him to be able to access his private wireless network when he gets home. Usually, when I upgrade Ubuntu, I have his /home directory on another partition, so his wireless profile to his own network persists. However, right now, I'm trying to figure out which .folder I need to copy from his /home/user folder on the old hard drive, to the new hard drive, so that he will be able to have wireless Internet when he gets home. Does anyone know with certainty, exactly which folder I need to copy to the new hard drive to achieve this?

• WPF ComboBox Binding + Selected Index for object.

  - by abmv

  I have a case of WPF binding I want to solve: The issue is that I have a user detail screen and it has a employee combo box that gets filled with employees. cbxEmployee.ItemsSource = DataAccess.GetCollectionView("Employee", "[Active] = True", viewModel.Context); cbxEmployee.DisplayMemberPath = "FullName"; cbxEmployee.SelectedValuePath = "ID"; The binding in user detail screen xaml is for the user object, I just need the employee id to store in the int property.So no problems when the user selects an employee. <ComboBox x:Name="cbxEmployee" SelectedItem="{Binding Path=Employee,ValidatesOnExceptions=True}" SelectedValue="{Binding Path=AssociatedEmployeeId}" Style="{DynamicResource InputBaseStyle}"/> Now the issue is that when an existing object is edited I need the combo box to get the correct employee to be shown,i.e the index should be set at the correct employee for the AssociatedEmployeeId of the user object. Well how the heck should I do it ? Any advice?

• Using AND/OR mysql commands with FROM_UNIXTIME

  - by scatteredbomb

  Trying to select a query in php/mysql to get "Upcoming Items" in a calendar. We store the dates in the DB as a unix time. Here's what my query looks like right now SELECT * FROM `calendar` WHERE (`eventDate` > '$yesterday') OR (FROM_UNIXTIME(eventDate, '%m') > '$current_month' AND `$yearly` = '1') ORDER BY `eventDate` LIMIT 4 This is giving me an error "Unknown column '' in 'where clause'". I'm sure it has to do with my use of parenthesis (which I've never used before in a query) and the FROM_UNIXTIME command. Can someone help me out and let me know how I've screwed this up? Thanks!

• Execute a method less times possible - PHP

  - by serhio

  I have a site in multiple languages. I have a method that returns me the today currencies in a array. I display that currencies in a table then. // --- en/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); // --- fr/index.php <?php include_once "../exchangeRates.php"; $currencies = ReadExchangeRates(); ... // somewhere in the page <td><?php echo $currencies["eur"]["today"]; ?></td> So, every time I load, en/ or fr/ or other language, I request the exchange rates from a external site. Can I optimize this behavior (reading once per day or session)? maybe to store a global variable and check the update date?

• MVC way of handling data input

  - by korki

  I have a data input module where I add the information of my product and its sub information like: product basic info product price info product price details price info and price details are related to product and are lists In my web forms approach I would store my main product object on the view state and I would populate it's pricing info and details while doing ajax postbacks. This way I can create a compact module that is very user friendly in terms of defining a lot of data from one place without the need to enter these data from seperate modules. And when I am done I would do one product.save() and that would persist all the data to the respective tables on db. Now I am building similar app on .net mvc framework and pondering on what would be the good way of handling this on mvc. I don't resonate towards storing all this on client side till I click save. And saving to the db after each action makes me remember the days I was coding on asp. Will appreciate your inputs on ways to approach this on mvc framework

• C string program

  - by mrblippy

  Hi, i have been given a task to do ar school that must read three strings in, store the third string in dynamically allocated memory and print out the last 4 letters of the first word alphabetically. Here is the program i have so far but the strings are all stored in different variables, making them hard to sort. if anyone could give me a hand and help me finish this program i would be very grateful. thanks #include <stdio.h> #include <stdlib.h> #include <string.h> int main() { char word1[101]; char word2[101]; char* word3; char buffer[101]; scanf("%s", word1); scanf("%s", word2); scanf("%s", buffer); word3 = (char *) malloc(strlen(buffer)+1); strcpy(word3, buffer); return 0; }

• Obtain all keys of a Neo4j index

  - by MattiSG

  I have a Neo4j database whose content is generated dynamically from a big dataset. All “entry points” nodes are indexed on a named index (IndexManager.forNodes(…)). I can therefore look up a particular “entry point” node. However, I would now like to enumerate all those specific nodes, but I can't know on which key they were indexed. Is there any way to enumerate all keys of a Neo4j Index? If not, what would be the best way to store those keys, a data type that is eminently non-graph-oriented? UPDATE (thanks for asking details :) ): the list would be more than 2 million entries. The main use case would be to never update it after an initialization step, but other use cases might need it, so it has to be somewhat scalable. Also, I would really prefer avoiding killing my current resilience abilities, so storing all keys at once, as opposed to adding them incrementally, would be a last-resort solution.

• Processing SMTP bounces with .net

Reading the related questions i find an interesting reference to [VERP]2. Under the heading 'Software that supports VERP i find that IIS is not on the list. Does that mean i need to find a library to integrate into my store's assembly? What resources do I have to pull together to make sure that the webapp is informed when mail bounces? fwiw - i'm working with a very low volume site.

• C String input confusion

  - by ahref

  C really isn't my strong point and after reading 3 chapters of a book on the subject and spending ages trying to get stuff working it just doesn't: #include <stdio.h> char *a,*b; int main( ) { char input[10]; fgets(input,sizeof input, stdin); a = input; fgets(input,sizeof input, stdin); b = input; printf("%s : %s",a,b); } I've isolated the problem from my main project. This code is meant to read in two strings and then print them however it seems to be setting a and b to point to input. Sample output from this code when A and B are entered is(don't worry about the \n's i can remove them): A B B : B How do i store the value of input in another variable eg. a or b so that in the above case A B A : B Is output? Thanks

• Where should common static resources (images, js, css, etc) go in DotNetNuke?

  - by Joosh21

  Is there a recommended location to store static resources (images, css, js, etc) in a DotNetNuke 5.x installation? There are /images and /js folders as well as a /Resources folder that contains resources. There appears to be some overlap as MicrosoftAjax.js is in multiple locations (but might be different versions?). I also could put resources in a /DesktopModule/ModuleX location. Does anyone know if there is a difference in using any of these folders? I kinda like the idea of all static resources being under a common folder (/Resources) so I could set caching rule headers, permissions, etc on them in one place. Has anyone used a separate image server to serve DotNetNuke static content? http://stackoverflow.com/questions/913208/pros-and-cons-of-a-separate-image-server-e-g-images-mydomain-com

• Is it possible to reference a file stored in Isolated Storage by its URI?

  - by Joel

  Using this previous question as motivation, I would like to temporarily store images and videos in Isolated Storage. My application (written in WPF/C#) will allow a user to review these temporarily stored items by viewing their contents in a MediaElement. I was hoping to set the MediaElement's Source Property to a video or image's URI stored in IsolatedStorage but I cannot figure out how to dynamically create a URI since it doesn't appear to be naively supported by IsolatedStorage. Any help would be greatly appreciated - thank you in advance! Update - 1/21/09 After battling the issue for a day, I concluded that the Isolated Storage approach is not practical for storing large video files that need to be referenced by a Uri.

• The conventional location for storing my Java libraries and applications in UNIX based systems

  - by Bytecode Ninja

  I usually store the Java applications and JAR files that I download from the Web in the ~/Java folder on my computer (an OS X machine). I have been doing this since the days when I was a Windows user. However I think in UNIX based systems user local apps are conventionally stored in another directory. I have a feeling that this directory should either be /usr/local/, /usr/local/USERNAME, /opt/local, or /opt/local/USERNAME but I am not sure. Any ideas which directory can I use for this purpose? Please note that, I am talking about archive files that I download from the Web, unpack and use locally and not programs that have installation scripts or MacPorts, etc.
