• Implementing simple business model in Haskell

  - by elmes

  Supose we have a very simple model: Station has at least one Train Train has at least two Stations The model has to allow to check what stations any given train visits and to check what trains visit a particular station. How to model it in Haskell? I am a Haskell newbie, so please correct me: once an object is created, you cannot modify it - you can only make a new object based on that one (~immutability). Am I right? If so, I'll have to create a lot of temporary variables with semi-initialized objects (during deserialization or even in unit tests). Basically what I need is an example of modeling domain classes in Haskell - after reading "Learn you a haskell.." I still have no idea how to use this language.

• MS Outlook Voting mismatch

  - by Robert Ilbrink

  I did send out an Outlook vote to hundreds of employees, using their email address (which is mostly [email protected], but there are many exceptions). The incoming votes are not matched against the email address, but against the display name. Unfortunately, the display name has no real standard either. So instead of seeing this: [email protected] Voted: Yes [email protected] Voted: No I see this: [email protected] [email protected] Doe, Johnathan Philip Voted: Yes Doe - Peeters, Marian Voted: No In the actual list I see the addresses that I sent the vote to PLUS extra lines with the votes that came back. Is there a quick way to match my "send" list with the "received" list? One thing I thought of was to dump the global address book in a file and in Excel use =vlookup. But that seems a lot of work (and I am not even sure that I have the authorization to dump the address book).

• Tools to manage large network of heterogeneous web applications?

  - by Andrew

  I recently started a new job where I've been tasked with managing a global network of heterogenous web applications. There's very little documentation. My first order of business is to create an inventory of all of the web applications. Are there any tools out there to manage a large group of web apps? I'd like to collect a large dataset for each website including: logins for web based control panels logins to FTP/ssh accounts Google analytics tracking code for each site 3rd party libraries used SSL certs, issuers, and expiration dates etc I know I could keep the information in Excel or build a custom database, but I'm hoping there's already a tool out there to help me with this.

• Finding Line Beginning using Regular expression in Notepad++

  - by Michel Merlin

  Finding Line Beginning using Regular expression in Notepad++ (Sorry if this is a newbie question) I want to strip a 4000-line HTML file from all the jQuery "done" stuff, e.g.: <DIV class=menu done27="1" done26="0" done9="1" done8="0" done7="1" done6="0" done4="20"> should be replaced with: <DIV class=menu> In http://www.zytrax.com/tech/web/regex.htm#experiment I can do it with RE: [ ^]done[0-9]+="[0-9]+" but in Notepad++ 5.6.8 UNICODE, in a .HTM file encoded in ANSI, Search Find, Search mode = Regular expression, putting this RE in the "Find what" field won't work (it will only find the 5 occurrences starting with a space, it will miss the 2 occurrences starting at the beginning of a line; IOW, the caret for line beginning, or the alternating it with a space, fails). How do I? TIA, Versailles, Wed 21 Apr 2010 10:42:20 +0200

• Adding and Testing Compatibility of External Jar to Blackberry Project

  - by pujakhemka

  Hi, I am a newbie at Blackberry development. I have Eclipse 3.5.1 and Blackberry JRE 4.7.0. In my application, I added 2 external jars to my project and a properties file. I do not know for sure whether the jars I am trying to add and the webservices I am calling are compatible with Blackberry. I have to test that too. When I tried running my project, I get - "Project has verification Error". Is it because I did not add the external jars correctly? Or is it because the jars may not be compatible with Blackberry?

• Drupal : Custom views filter

  - by Joseph

  Hi, First thing I would say is that I am a Drupal newbie. So, I would appreciate your answer in a detailed step by step process. I am using Drupal 6 and location module. There are two main content types - user profile (using content profile module) and event content type. Both have one field for location. Now, lets suppose in his profile, user is selecting city as Toronto and province as Ontario. And some events have been added for Toronto city. I need one Views, which will display events from user city. So, if user is from Vancouver, and they click on "my city events", they will see list of events from their city. Someone told me that I can achieve this using arguments/ relationships, but I don't know how to do that. Can someone please help me out? I am not good at PHP either :(

• Handling Session ID with Spring

  - by Max

  Hi, I'm trying to build a Spring server for GWT (you can think of it as of Javascript AJAX client). But I can't decide on one point of architecture. How should session be created and used? The obvious easiest way - is to use HTTP sessions (cookies and stuff). Looks fine, but I think that sending session ID separate from the headers would be better (SOAP style). So, what is better: getMyPetsName(String sessionID, int petID) or getMyPetsName(int petID) + session ID through HTTP header (cookies or something). Another question is, if I use the first way (which I like more) - how do I handle session in Spring? I'm really newbie in Spring, and googling did not help. What I mean is: String getMyPetsName(String sessionID, int petID) { Session s = someWayToGetItById(sessionID); } Thanks in advance.

• Webpage / Other application does not fit fully on screen

  - by Frank Levebre

  I have an ASUS Eee PC 1008 HA The problem is that I have to move the cursor up/down in order to see the start control / icons at the bottom of the screen and the cursor up in order to see the menu bar / etc at the top of the screen, ie the whole page does not fit on the screen anymore. It has nothing to do with the zoom % in the bottom right hand corner. This also is the case whatever application I am running, ie Internet explorer , word, excel or whatever. Does anybody have an idea what is the problem and how I can resolve this?

• My powershell script wont save a file when run using Task Scheduler, do I need to specify a specific argument?

  - by EGr

  I have a script that downloads a temporary Excel file, copies parts of it to a new file, and saves it to a specific location on the network. The problem I'm having is that the new file is never created/saved. If I run the script locally (through cmd.exe, powershell, or powershell ise), it WILL save the file locally, or to the network. If I try running the script via a schedule or on-demand via Task Scheduler, the temporary file is created, but the final document is never created or saved. Is there a specific argument I need to pass, or anything I could be doing wrong? This is the command I'm currently using: powershell.exe -file C:\path\to\my\powershell\script\thescript.ps1 Since it calls environment variables, and other variables relative to the scripts positon, I also set "Start in" to C:\path\to\my\powershell\script\

• Select firefox search result

  - by Nicolas C.

  I am working on a daily basis on a web application with very large menus. Also doing lots of other Excel manipulations, copy and pasting, etc., I am quite fond of keyboard shortcuts as much faster than using the mouse to point, double-click and then going back to my keyboard etc. Hence, my question is quite simple, does anyone know if there is any shortcut under Firefox which would let me actually select (and not highlight) in my web page the search result so that I can for instance do the following manipulation sequence? [Ctrl]+[F] type the search string, for instance 'regional_unit' the missing shortcut to actually select in my page the string which is currently highlighted thanks to the search feature of FF [Space] or [Enter] key to activate the web element which in my case would systematically correspond to a link or button, etc. May be there would be an addon replacing the default search feature, I don't know... I tried to look over the internet but with the words I am using for this investigation, I do not get relevant search results under Google :(. Thanks a lot

• There is a problem with the Office database

  - by RomanT

  After a TimeMachine restore; office 2011 is having kittens over permissions it would seem. Having attempted a 'repair' out of Disk Utility, am still seeing: 'there is a problem with the Office database' upon startup. After which Word/Excel work without issues. Outlook on the other hand won't even start. Given the obvious message here "You do not have write access to the Outlook application folder" - where is the DB located to check?! Ideas ? Thank you

• What's the deal with NTFS tags in windows 7

  - by polarix

  So back in the days of 'longhorn' there was this WinFS idea which was both cool looking and scary looking. Then it seemed to disappear, but we were told that many of the concepts would be rolled into Vista. Then maybe Win7. Anyway, nowadays if you look at a win7 Explorer window, you can have columns that have a lot of tag-based info about a file (right click on column header-more...), including one called "tags". Is this something in NTFS that can be modified per-file somehow? Is its GUI hiding, or is this something that's infinitely-delayed, or is it just a figment of my imagination? Sure would be nice to be able to get around the NTFS path 256 character limit for searches, and to filter file folders per Excel 2007.

• AVD Failed to Load ~ Failed to Parse Properties ~ Mac OSX

  - by C.D. OKeefe

  I'm going to say upfront, please forgive me. I'm a newbie to android development and fairly new to programming. Also on a Mac. You're going to have to talk...real...slow. I can't get an AVD to load. I've tried it from Eclipse and from the Android SDK Manager. Failed multiple times. Received the same error each time, "Failed to parse properties from Users/myname/.android/avd/nameIGaveEmulator/config.ini." I've the forum here and saw that others have had similar problems, but of the answers given, no one came back to say if they worked, and I don't see anyone with a similar problem on a Mac. If the path needs to be "changed" what exactly does that mean and how do I go about doing so?

• How necessary is using PHP filters?

  - by Jamie

  I'm a relatively newbie to PHP and just making my way through the W3Schools tut. The tut makes a big point of saying you must always filter external data (i.e. cookies, form data etc). I'm writing a fairly simple system that talks with a third party Joomla extension. It's at a prototype stage where I'm just wanting to demonstrate the functionality in a minimum viable product. Basically, I'd like to know... what's the worst that could happen in I don't filter content. Are we talking 'I might get a bunch of spam', or 'a good hacker could get root server access'? Have hunted around online, but would love any of your experience / insight on the matter!

• Using list comprehension in Python to do something similar to zip()?

  - by jamieb

  I'm a Python newbie and one of the things I am trying to do is wrap my head around list comprehension. I can see that it's a pretty powerful feature that's worth learning. cities = ['Chicago', 'Detroit', 'Atlanta'] airports = ['ORD', 'DTW', 'ATL'] print zip(cities,airports) [('Chicago', 'ORD'), ('Detroit', 'DTW'), ('Atlanta', 'ATL')] How do I use list comprehension so I can get the results as a series of lists within a list, rather than a series of tuples within a list? [['Chicago', 'ORD'], ['Detroit', 'DTW'], ['Atlanta', 'ATL']] (I realize that dictionaries would probably be more appropriate in this situation, but I'm just trying to understand lists a bit better). Thanks!

• ns-2 c++ file changes

  - by stanigator

  I have just installed a network simulator program called ns-2 and I am trying to familiarize myself with it by going through the tutorial by Marc Greis. When I get to the stage where I'm messing around with C++ source files and related program C++ source files as stated in http://www.isi.edu/nsnam/ns/tutorial/index.html, I don't know what to do as there are enough inconsistencies between the version of ns-2 that I downloaded (which is the latest stable build) and the guide. What would your recommendations in this case, as I don't know what to do with it as a newbie? Thanks in advance for your help!

• Storing CLLocationCoordinates2D in NSMutableArray

  - by Amarsh

  After some searching, I got the following solution : ref: http://stackoverflow.com/questions/1392909/nsmutablearray-addobject-with-mallocd-struct CLLocationCoordinate2D* new_coordinate = malloc(sizeof(CLLocationCoordinate2D)); new_coordinate->latitude = latitude; new_coordinate->longitude = longitude; [points addObject:[NSData dataWithBytes:(void *)new_coordinate length:sizeof(CLLocationCoordinate2D)]]; free(new_coordinate); And access it as: CLLocationCoordinate2D* c = (CLLocationCoordinate2D*) [[points objectAtIndex:0] bytes]; However, someone claims that there is a memory leak here? Can anyone suggest me where is the leak and how to fix it. Further, is there a better way of storing a list of CLLocationCoordinate2D in NSMutableArray? Please give sample code since I am an Objective C newbie.

• Creating a custom view for windows log based on a "Contains {text}" rule

  - by jussinen

  I have a server running Windows Server 2008. I'm using Windows Server Auditing to check when and by which user a folder is modified to determine who is modifying it as the modifications are causing problems. I can see the log of the audit when a change is made in the System log. How do I create a Custom View that will return all events from System log where a certain text (which is the folder name) is present? The create custom view doesn't seem to have that option. I'm not sure whether it's possible via custom xml query or whether I'll need to export the system log to csv and search in Excel. John

• What is annotations and how do it actually works for frameworks like Spring ?

  - by Rachel

  I am new to Spring and now a days I hear a lot about Spring Framework. I have two sets of very specific questions: Set No. 1: What are annotations in general ? How does annotations works specifically with Spring framework ? Can annotations be used outside Spring Framework or are they Framework specific ? Set No. 2: What module of Spring Framework is widely used in Industry ? I think it is Spring MVC but why it is the most used module, if am correct or correct me on this ? I am newbie to Spring and so feel free to edit this questions to make more sense.

• C++ -malign-double compiler flag

  - by Martin

  I need some help on compiler flags in c++. I'm using a library that is a port to linux from windows, that has to be compiled with the -malign-double flag, "for Win32 compatibility". It's my understanding that this mean I absolutely have to compile my own code with this flag as well? How about other .so shared libraries, do they have be recompiled with this flag as well? If so, is there any way around this? I'm a linux newbie (and c++), so even though I tried to recompile all the libraries I'm using for my project, it was just too complicated to recursively find the source for all the libraries and the libraries they're dependent on, and recompile everything.

• How do I get the path of the current executed file in python?

  - by Sorin Sbarnea

  This may seam a newbie question but it is not. It looks that common approaches are not always working: Currently I know only two options but none of them looks to work an all cases. sys.argv[0] This means using path = os.path.abspath(os.path.dirname(sys.argv[0])) but this does not work if you are running from another python script from another directory, and this can really happen in real life. __file__ this means that path = os.path.abspath(os.path.dirname(__file__)) but I found that this doesn't work: py2exe that doesn't have a __file__ attribute but there is an workaround. when you run from IDLE with execute() there is no __file__ attribute OS X 10.6 where I get NameError: global name '__file__' is not defined Related questions with incomplete answers: http://stackoverflow.com/questions/1296501/python-find-path-to-file-being-run http://stackoverflow.com/questions/1483827/python-path-to-current-file-depends-on-how-i-execute-the-program http://stackoverflow.com/questions/2259503/how-to-know-the-path-of-the-running-script-in-python http://stackoverflow.com/questions/509742/python-chdir-to-dir-the-py-script-is-in
