• Best way in Python to determine all possible intersections in a matrix?

  - by ssweens

  So if I have a matrix (list of lists) of unique words as my column headings, document ids as my row headings, and a 0 or 1 as the values if the word exists in that particular document. What I'd like to know is how to determine all the possible combinations of words and documents where more than one word is in common with more than one document. So something like: [[Docid_3, Docid_5], ['word1', 'word17', 'word23']], [[Docid_3, Docid_9, Docid_334], ['word2', 'word7', 'word23', 'word68', 'word982']], and so on for each possible combination. Would love a solution that provides the complete set of combinations and one that yields only the combinations that are not a subset of another, so from the example, not [[Docid_3, Docid_5], ['word1', 'word17']] since it's a complete subset of the first example. I feel like there is an elegant solution that just isn't coming to mind and the beer isn't helping. Thanks.

• loading an image from a package in Java (JFrame)

  - by Shahar Kazaz

  i'm having a problem loading an image from a package i created in the project that was set to contain images, i have to write the whole picture location in the computer instead of just the package that contains it. i've tried several things but nothing seams to work... where is the command i use to load the image : searchBar = ImageIO.read(new File("C:\\Users\\ASUS\\Documents\\NetBeansProjects\\Project\\src\\Images\\search.jpg")); "Images" is a package in my project , this works, but when i try loading the image without the "C:\..." only with the "\Images..." it doesn't , so i have to change it every time i open this project in another computer. hopefully one of u has the answer for me , thanks in advance for any answer :)

• ModX navigation menu with "wayfinder" snippet

  - by user1219432

  I have a main navigation at the top of the site. And a subnavigation at left of my site. For example: At the top there are these topics: Cars | Trees | Jobs | ... So when you click on "Jobs" there should be the subnavigation of "Jobs" at left, like... Construction Jobs Engineering Jobs Retail Jobs ... The first (top) navigation is easy to achieve: [[!Wayfinder? &startId=0 &level=1 ]] How can I realize the second navigation, so that only the documents are listed that are under the parent document?

• Looking to redo a static website

  - by moorecats

  I have been asked to help redo my non-profit website. I would like to make it look better. What would be the best way to do this? I have some technical background and can learn. I have looked at various options such as Joomla, word press and so on but I am not certain on how to create a good UI for it. I have also looked at Ruby and such, which I think may be overkill for a static page such as this. I haven't done any programming etc in a few years, but I figure this may be an opportunity to get back into it.

• Find objects between two dates MongoDB

  - by Tom

  I've been playing around storing tweets inside mongodb, each object looks like this: { "_id" : ObjectId("4c02c58de500fe1be1000005"), "contributors" : null, "text" : "Hello world", "user" : { "following" : null, "followers_count" : 5, "utc_offset" : null, "location" : "", "profile_text_color" : "000000", "friends_count" : 11, "profile_link_color" : "0000ff", "verified" : false, "protected" : false, "url" : null, "contributors_enabled" : false, "created_at" : "Sun May 30 18:47:06 +0000 2010", "geo_enabled" : false, "profile_sidebar_border_color" : "87bc44", "statuses_count" : 13, "favourites_count" : 0, "description" : "", "notifications" : null, "profile_background_tile" : false, "lang" : "en", "id" : 149978111, "time_zone" : null, "profile_sidebar_fill_color" : "e0ff92" }, "geo" : null, "coordinates" : null, "in_reply_to_user_id" : 149183152, "place" : null, "created_at" : "Sun May 30 20:07:35 +0000 2010", "source" : "web", "in_reply_to_status_id" : { "floatApprox" : 15061797850 }, "truncated" : false, "favorited" : false, "id" : { "floatApprox" : 15061838001 } How would I write a query which checks the *created_at* and finds all objects between 18:47 and 19:00? Do I need to update my documents so the dates are stored in a specific format? Thanks

• Porting existing code from C# 2.0 to C#3.0 and .Net 3.5 (possibly .net 4.0)

  - by kanad

  Our one and only enterprise application suite has been developed over last 3 years using C# 2.0 on .Net 3.0. We use winforms and WCF heavily. The development tools is VS 2005 Pro / TFS 2005 / Resharper 3.1 As technical lead I obviously understand the benefits in a move to C#3.0 and .Net 3.5. But I want to convince management for a move to C#3.0, .Net 3.5, VS 2008 and TFS 2008. They will obviously be interested in things like productivity, cost, quality etc. Please suggest me some ideas on how best to make my case. Given that this may not happen till mid next year am I better off to hold till VS 2010 and .Net 4.0 is out.

• Error becuase Virtual directory not being configured as an application in IIS

  - by Cipher

  Hi, I was trying to install a CMS in a folder in my website. After the installation on trying to run, it shows this error: Error 14 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. E:\Users\Sarin\Documents\Visual Studio 2010\WebSites\WebAssist\blog\web.config 61 I added the webiste as a Virtual Directory and also converted that to application. On trying to browse this application, the following error occurs as shown in the screenshot: http://i.imgur.com/jcRJe.jpg How to make this work?

• Upload file from client machine to server - prepopulate file picker path?

  - by user246114

  Hi, I'd like to upload a file from a client machine to my server. The user would have to specify the file to upload as I understand it, using a form that looks like: <input type="file" name="datafile" size="40"> This pops up a native file picker, which is great. The problem I'm having is that it's a real pain (for most users) to go looking around their machine for the file I'm interested in. Is there a way I can initialize the file picker with a path to make it more convenient for the user? Like I know some users will be on a windows machine, so I could prepopulate the picker by already sending them to the My Documents folder for example. I don't see how this is possible, just wondering if something like that exists, Thank you

• I need a very simple PHP database front-end admin panel; a simple records editor for a specified tab

  - by Lansen Q

  Hi there, I am looking to add some dynamics to our corporate website. This is a secondary role so I'd rather not be spending a ton of time on it. At this point, all I need is a simple PHP script where a non-technical user can pull up and manage the records in a MySQL table. There's only one table of data to be managed; it's just that it will be accessed and updated quite frequently. I recall that Grails' default scaffolding feature has precisely this: list of entries with the ability to add, edit and delete, with no nonsense. What would be the best tool to use for this? I would rather not be writing it from scratch, as this will take me quite some time. It seems like the kind of thing that ought to exist somewhere. Thanks!

• Query Mongo Db and filter by associative array key

  - by Failpunk

  How can I search for results in Mongo DB documents using an associative array key. Something like: SELECT * FROM table WHERE keyword like '%searchterm%'; Here is the basic document structure [id] => 31605 [keywords] => Array ( [keyword1] => Array ( [name] => KeyWord1 ) [keyword2] => Array ( [name] => KeyWord2 ) ... ) I would like to do a search within the keywords array on the associative array key [keyword1, keyword2]. The issue is that the name key holds the case-sensitive version of the keyword and the array key is the lower-case keyword name. I could store the lowercase keyword twice, but that seems silly.

• PHP HTML variable

  - by Abakiz Myth

  In Coldfusion we have the variable: <cfsavecontent name="HTML_content"> <div class="test_div" style="color:#FFF;">Test</div> </cfsavecontent> Within PHP there seems to be no way of doing this without some really hacky function or escaping double quotes. I'm trying to create emails (large html documents) within the same page by saving the email content and simply mailing it but it seems like there's no way of doing this within PHP without using $var = "\"crap\""; Can somebody point me in the right direction?

• Why do we need Web-Api? [closed]

  - by user437973

  I was just wondering what the deal is with Asp.net Web-Api. Why did we need a separate type of controller in order to facilitate varying content types for action results? Why wasn't this capability just baked into the ASP.Net MVC base controller? Anyway, I was just wondering if there was a compelling reason to use both types of controllers within the same project, assuming that the project was being freshly created, or if this project structure was due to an inherent technical limitation. Would it be possible to have ApiControllers fulfill the purpose of an MVC Controller in all cases by just serving HTML when that is the specified accept type? It just seems to me like a lot of unnecessary repetition to have to re-implement the same types of actions using both types of controllers if you want those actions to be available to your web application through the API and through the web interface.

• Scheduling a visual studio load test using powershell giving me BSOD

  - by user952342

  I have a visual studio load test which I want to run every hour so that I can start to collect some data. To do this, I thought it would be best to make a little powershell script and put a command like this inside: Invoke-Expression -command "& '$env:VS100COMNTOOLS..\IDE\mstest.exe' /testcontainer:"C:\Users\benb\Documents\Visual Studio 2010\Projects\BBPerformanceTest\bin\Debug\HomePageOnly.loadtest"" That command works fine, but sometimes when its run I get a blue screen of death. However, when I run my load test through the visual studio GUI, I never get a BSOD. two questions: is it possible to avoid this BSOD? Is there another way I can schedule my load test? Thanks

• How to structure data... Sequential or Hierarchical?

  - by Ryan

  I'm going through the exercise of building a CMS that will organize a lot of the common documents that my employer generates each time we get a new sales order. Each new sales order gets a 5 digit number (12222,12223,122224, etc...) but internally we have applied a hierarchy to these numbers: + 121XX |--01 |--02 + 122XX |--22 |--23 |--24 In my table for sales orders, is it better to use the 5 digital number as an ID and populate up or would it be better to use the hierarchical structure that we use when referring to jobs in regular conversation? The only benefit to not populating sequentially seems to be formatting the data later on in my view, but that doesn't sound like a good enough reason to go through the extra work. Thanks

• How to ignore an exception and continue processing a foreach loop?

  - by Barry Dysert

  I have a test program that is supposed to loop over all the files under C:. It dies when it hits the "Documents and Settings" folder. I'd like to ignore the error and keep looping over the remaining files. The problem is that the exception is thrown in the foreach, so putting a try/catch around the foreach will cause the loop to exit. And putting a try/catch after the foreach never fires (because the exception is thrown in the foreach). Is there any way to ignore the exception and continue processing the loop? Here's the code: static void Main(string[] args) { IEnumerable<string> files = Directory.EnumerateFiles(@"C:\", "*.*", SearchOption.AllDirectories); foreach (string file in files) // Exception occurs when evaluating "file" Console.WriteLine(file); }

• New replicaset resident memory is larger than the existing sets

  - by eded

  From the mongodb tutorial of how to resync a set, I wipe all the files in /data/db and restart the mongod process to resync the data. Everything looks ok, I get the same number of documents as the existing two sets(primary and one secondary). However, when I check the memory on MMS. it shows me my new resynced set/mongod process has a different memory status value than the other two. For existing twos using db.serverStatus.mem shows like the following: "mem" : { "bits" : 64, "resident" : 239, "virtual" : 66348, "supported" : true, "mapped" : 32865, "mappedWithJournal" : 65730 } however, the new resynced set shows like: "mem" : { "bits" : 64, "resident" : 1239, "virtual" : 52447, "supported" : true, "mapped" : 25700, "mappedWithJournal" : 51400 } the resynced resident memory is 6-10 times more than the existing ones. I wouder if it is normal because all data comes in suddenly during the resyncing?? and even virtual and mapped value are different too. Can anyone explain?? thanks

• Save information from MS crash reporter?

  - by DGentry

  On Windows XP when a process crashes, we get a dialog box with a link: "To view technical information about the error report, click here." The "click here" link brings up a whole lot of information in a window, but no obvious way to save it to a file. Is there a way? It would be very nice to be able to send that data to several different external vendors we're working with. The only other option I see in the dialog box is to send it to Microsoft, but this crash is likely not Microsoft's fault and there is no reason to send it to them.

• Python 2.6 - I can not write dwords greater than 0x7fffffff into registry using _winreg.SetValueEx()

  - by stasizke

  using regedit.exe I have manually created a key in registry called HKEY_CURRENT_USER/00_Just_a_Test_Key and created two dword values dword_test_1 and dword_test_2 I am trying to write some values into those two keys using following program import _winreg aReg = _winreg.ConnectRegistry(None,_winreg.HKEY_CURRENT_USER) aKey = _winreg.OpenKey(aReg, r"00_Just_a_Test_Key", 0, _winreg.KEY_WRITE) _winreg.SetValueEx(aKey,"dword_test_1",0, _winreg.REG_DWORD, 0x0edcba98) _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) _winreg.CloseKey(aKey) _winreg.CloseKey(aReg) I can write into the first key, dword_test_1, but when I attempt to write into the second, I get following message Traceback (most recent call last): File "D:/src/registry/question.py", line 7, in <module> _winreg.SetValueEx(aKey,"dword_test_2",0, _winreg.REG_DWORD, 0xfedcba98) ValueError: Could not convert the data to the specified type. How do I write the second value 0xfedcba98, or any value greater than 0x7fffffff as a dword value? Originally I was writing script to switch the "My documents" icon on or off by writing "0xf0500174" to hide or "0xf0400174" to display the icon into [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID{450D8FBA-AD25-11D0-98A8-0800361B1103}\ShellFolder]

• Program not running from expected directory?

  - by twpc

  I am working on a web-based program, using Java. I am not sure exactly how to phrase this, but I expect the program to be running from within the c:/Resin/webapps/apps directory. However, when I reference a file in the program like this: "../files/randomfile.pdf", it cannot find that file. It works when I reference it like this: "c:/Resin/webapps/files/randomfile.pdf". How to I change the "running location"? (And what is the technical term for this?)

• While programming, what to do when facing with a seemingly unsolvable situation with a time limit?

  - by Ersan Tasan

  This is not a technical question, but rather a social and methodical one. I am a computer sciences student and I usually have really tough programming assignments. I don`t know if it is only happening to me but sometimes, particularly when deadline is approaching, i find myself in a harsh situation. I cannot find my mistake in the code or come up with a another great idea. Then boredom comes in and the problem begins to seem unsolvable. I know there are more-than-great professional coders here. I would like to learn their ideas to cope with this situation. Is it better to focus on something else for a while and try again or try harder and harder and look for the solution on the net etc...

• Delete files in C# that windows does not want me to delete?

  - by user315881

  At my company, we are writing a script to take care of simple tasks that we usually would do by hand. I am using c# to delete profiles in c:\documents and settings\, except a few. These will simply be left alone. The problem is that even with code that sets the files to normal and marks the admin user as an owner, they won't delete. They say that the quick launch folder has access denied. I am using a recursive permissions change method and I know that it works. Same thing with file attributes. Why won't it work? How do I fix this?
