• Assign grid.arrange to object

  - by Tyler Rinker

  I want to arrange plots with grid.arrange to make more complex coplots and then use grid.arrange to combine these complex coplots. I am using the following solution (http://stackoverflow.com/a/13295880/1000343) in this task to arrange mutliple plots and ensure they have equal widths. Here is a demo of the code: library(ggplot2); library(gridExtra) gA <- ggplotGrob(A) gB <- ggplotGrob(B) maxWidth = grid::unit.pmax(gA$widths[2:5], gB$widths[2:5]) gA$widths[2:5] <- as.list(maxWidth) gB$widths[2:5] <- as.list(maxWidth) x <- grid.arrange(gA, gB, ncol=1) y <- grid.arrange(gA, gB, ncol=1) grid.arrange(x, y, ncol=2) To be clear in my case x and y are slightly different plots with different values. I know grid.arrange isn't returning the plot as other grid based functions.

• Working with Japanese filenames in PHP 5.3 and Windows Vista?

  - by Jon

  I'm currently trying to write a simple script that looks in a folder, and returns a list of all the file names in an RSS feed. However I've hit a major wall... Whenever I try to read filenames with Japanese characters in them, it shows them as ?'s. I've tried the solutions mentioned here: http://stackoverflow.com/questions/482342/php-readdir-problem-with-japanese-language-file-name - however they do not work for some reason, even with: header('Content-Type: text/html; charset=UTF-8'); setlocale(LC_ALL, 'en_US.UTF8'); mb_internal_encoding("UTF-8"); At the top (Exporting as plain text until I can sort this out). What can I do? I need this to work and I don't have much time.

• Why is this Python class copying another class contents?

  - by fjfnaranjo

  Hello guys. I'm trying to understand an estrange behavior in Python. I have the next python code: class IntContainer: listOfInts = [] def __init__(self, initListOfInts): for i in initListOfInts: self.listOfInts.append(i) def printInts(self): print self.listOfInts if __name__ == "__main__": intsGroup1 = [1,2,3,4] intsGroup2 = [4,5,6,7] intsGroups = [intsGroup1,intsGroup2] intsContainers = [] for ig in intsGroups: newIntContainer = IntContainer(ig) intsContainers.append(newIntContainer) for ic in intsContainers: print ic.listOfInts I expect to get something like: [1, 2, 3, 4] [4, 5, 6, 7] But i get: [1, 2, 3, 4, 4, 5, 6, 7] [1, 2, 3, 4, 4, 5, 6, 7] I have check the next question: http://stackoverflow.com/questions/1876905/why-is-python-reusing-a-class-instance-inside-in-function And a lot of Python reference, but I can not understand what is happening. I think is related with the newIntContainer identifier reutilization, but I do not understand it deeply. Why Python appears to reused the last reference for the new object, even if I have added it to a permanent list? What can I do to resolve this behavior? Thanks ;)

• How can I measure distance with tastypie and geodjango?

  - by Twitch

  Using Tastypie and GeoDjango, I'm trying to return results of buildings located within 1 mile of a point. The TastyPie documentation states that distance lookups are not yet supported, but I am finding examples of people getting it work, such as this discussion and this discussion on StackOverflow, but no working code examples that can be applied. The idea that I am trying to work with is if I append a GET command to the end of a URL, then nearby locations are returned, for example: http://website.com/api/?format=json&building_point__distance_lte=[{"type": "Point", "coordinates": [153.09537, -27.52618]},{"type": "D", "m" : 1}] But when I try that, all I get back is: {"error": "Invalid resource lookup data provided (mismatched type)."} I've been pouring over the Tastypie document for days now and just can't figure out how to implement this. I'd provide more examples, but I know they'd be all terrible. All advice is appreciated, thank you!

• jquery/ajax load new content when available

  - by Tim

  I know this is quite a vague question -- sorry about that. If I have a forum, shoutbox or something similar where users enter and submit data, running on PHP and MySQL, what is the best way to have the newly submitted content automatically display on the page for all users when it is submitted? Much like a live newsfeed, if you like... The effect sort-of works here at stackoverflow, when you are answering a question you are told when new answer is submitted. I want to test for newly submitted content and then display it automatically. Any suggestions? Many thanks :)

• Zend disableLayout() leaves html & body tags in output

  - by sunwukung

  Hi all, could anyone take a look at this for me? Problem: trying to output a csv on demand using Zend Framework. I want to avoid creating files on the system so I'm trying to use the same solution posted here: http://stackoverflow.com/questions/1136264/export-csv-in-zend-framework However - I'm still getting html and body tags in the csv. I'm setting layouts in the ini file. I've tried putting the csv call earlier in the request cycle using preDispatch etc - but to no avail. Any help is greatly appreciated SWK

• Send files between python+django and C#

  - by SuitUp

  Hi, i would like to know, what is the best way to send files between python and C# and vice versa. I have my own protocol which work on socket level, and i can send string and numbers in both ways. Loops works too. With this i can send pretty much anything, like package of users id, if it is simple data. But soon i will start sending whole files, maybe xml or executables. Simple server with files is no an option because i want sending files from client too. I was thinking about serialization but i don't know it is the best solution, but if it is i will love some tips from stackoverflow community. EDIT: I added django to question and chose using http.

• Timeout not working in SQL Connection

  - by carlos

  I have this simple code to test that a DB is ready: Function testlocalcon() As Boolean Dim constr As String = _clconstr Try Using t As New SqlConnection() constr = constr & " ; Connect Timeout=1" If Not t.State = Data.ConnectionState.Open Then t.ConnectionString = constr t.Open() If t.State = Data.ConnectionState.Open Then Return True Else Return False End If Else Return True End If End Using Catch ex As Exception Return False End Try End Function I do not want to execute a query, just to check the connection, but no matter what the time out parameter is ignored. I search here (Stackoverflow) and internet and found nothing in how to fix this. Any one else have this problem? Or, are there any other ideas on how to let the application know that the DB is ready?

• database search function on an HTML page possible?

  - by synergy989

  Not sure if this is against stackoverflow rules as it's not a specific code question but I really need a little help. I want to know if it is possible to create a search feature (search box) on an HTML webpage that will query a database and return the results? Basically I have a database of products and their related categories. A user would come to the website, enter the category in the search field...somehow query the database and return the results on a new page. Note: the results page doesn't have to be HTML (could be PHP etc). If you could also include a little guidance on how (please nothing detailed, just need a direction). Thank you!

• Can you Borrow a PDF?

  - by WeNeedAnswers

  What are the legalities of letting someone borrow a book that you have purchased that so happens to be in PDF format with no DRM? I know that I can lend a printed book to someone and this not infringe copyright, but a pdf? I know that the thought police are going to be on my case about "no one here is a legal expert" or the "question can't be answered" or "controversial", But I would like to have the opportunity to at least surface the issue, and allow people to comment. I am not looking for point scoring on this, or even an answer, but as stackoverflow has a rather large technical savvy audience that would appreciate the question I think that it could be the next hurdle that will stop technical progress.

• Mysql - Join matches and non-matches

  - by jwzk

  This is related to my other question: http://stackoverflow.com/questions/2579249/managing-foreign-keys I am trying to join the table of matches and non-matches. So I have a list of interests, a list of users, and a list of user interests. I want the query to return all interests, whether the user has the interest or not (should be null in that case), only where the user = x. Every time I get the query working its only matching interests that the user specifically has, instead of all interests whether they have it or not.

• Simple CArray questions

  - by Holli

  1.) What is the difference between CArray <SomeClass> collection; and CArray <SomeClass,SomeClass> collection; or even CArray <SomeClass* ,SomeClass* > collection; ? 2.) While reading some comments on Stackoverflow I came to a note saying "Don't use CArray". Why should CArray not be used?

• Python: How to quit CLI when stuck in blocking raw_input?

  - by christianschluchter

  I have a GUI program which should also be controllable via CLI (for monitoring). The CLI is implemented in a while loop using raw_input. If I quit the program via a GUI close button, it hangs in raw_input and does not quit until it gets an input. How can I immediately abort raw_input without entering an input? I run it on WinXP but I want it to be platform independent, it should also work within Eclipse since it is a developer tool. Python version is 2.6. I searched stackoverflow for hours and I know there are many answers to that topic, but is there really no platform independent solution to have a non-blocking CLI reader? If not, what would be the best way to overcome this problem? Thanks

• how to step into code from jars (non JDK) using IntelliJ?

  - by ascari

  I am new to IntelliJ (and Stackoverflow) and fairly new to Java,In my application I am using code from jars that in IntelliJ I added as "External Libraries". I also have the source code for those jars, but I rather not compile it (they are huge and complex). Now while debugging my application I would like to step into the library code that is compiled into those jars. How can I set up IntelliJ to do that? Is there another way other that attaching the entire jar library source code to my application code?

• PHP: Classes to use functions from each other?

  - by Martti Laine

  Hello I've been into this problem for a while already, and have asked some questions about it here Stackoverflow. I've got some advice, but I just can't understand it. Could someone provide me an example of classes working smoothly together. I have 3 (maybe more) classes: mysql user alerts As I said, could someone provide an example, so these classes could use functions from each other class, e.g. user could use mysql's functions. I'm asking for an simple example, for learning-purposes. And please, no google-suggestions or links to other questions. I've tried to search this for a while already. No success, though.

• [C++] Needed: A simple C++ container (stack, linked list) that is thread-safe for writing

  - by conradlee

  I am writing a multi-threaded program using OpenMP in C++. At one point my program forks into many threads, each of which need to add "jobs" to some container that keeps track of all added jobs. Each job can just be a pointer to some object. Basically, I just need the add pointers to some container from several threads at the same time. Is there a simple solution that performs well? After some googling, I found that STL containers are not thread-safe. Some stackoverflow threads address this question, but none form a consensus on a simple solution.

• Python: get windows OS version and architecture

  - by Thorfin

  First of all, I don't think this question is a duplicate of http://stackoverflow.com/questions/2208828/detect-64bit-os-windows-in-python because imho it has not been thoroughly answered. The only approaching answer is: Use sys.getwindowsversion() or the existence of PROGRAMFILES(X86) (if 'PROGRAMFILES(X86)' in os.environ) But: Can we completely rely on the windows environment variable PROGRAMFILES(X86)? I fear that anyone can create it, even if it's not present on the system. How can we use sys.getwindowsversion() to get the architecture? Regarding sys.getwindowsversion(): The link http://docs.python.org/library/sys.html#sys.getwindowsversion leads us to http://msdn.microsoft.com/en-us/library/ms724451%28VS.85%29.aspx but I don't see anything related to the architecture (32bit/64bit). Moreover, the platform element if the returned tuple seems to be independent of the architecture. One last note, I'm using python 2.5. Thanks!

  public static MySingleton getInstance() { if (_instance==null) { synchronized (MySingleton.class) { _instance = new MySingleton(); } } return _instance; } 1.is there a flaw with the above implementation of the getInstance method? 2.What is the difference between the two implementations.? public static synchronized MySingleton getInstance() { if (_instance==null) { _instance = new MySingleton(); } return _instance; } I have seen a lot of answers on the singleton pattern in stackoverflow but the question I have posted is to know mainly difference of 'synchronize' at method and block level in this particular case.

• Optimal search queries

  - by Macros

  Following on from my last question http://stackoverflow.com/questions/2788082/sql-server-query-performance, and discovering that my method of allowing optional parameters in a search query is sub optimal, does anyone have guidelines on how to approach this? For example, say I have an application table, a customer table and a contact details table, and I want to create an SP which allows searching on some, none or all of surname, homephone, mobile and app ID, I may use something like the following: select * from application a inner join customer c on a.customerid = a.id left join contact hp on (c.id = hp.customerid and hp.contacttype = 'homephone') left join contact mob on (c.id = mob.customerid and mob.contacttype = 'mobile') where (a.ID = @ID or @ID is null) and (c.Surname = @Surname or @Surname is null) and (HP.phonenumber = @Homphone or @Homephone is null) and (MOB.phonenumber = @Mobile or @Mobile is null) The schema used above isn't real, and I wouldn't be using select * in a real world scenario, it is the construction of the where clause I am interested in. Is there a better approach, either dynamic sql or an alternative which can achieve the same result, without the need for many nested conditionals. Some SPs may have 10 - 15 criteria used in this way
