  • Replace text in folder names

    - by dannyb
    How can I replace the same text in folder names in linux? Say I have "Photos_Jun", "Photos_July", "Photos_Aug", etc. whats the simplest way I can rename them like "Photos Jun", "Photos July", etc (basically I want to replace the underscore with a space " ". I have about 200 of these folders. I was looking at solution: http://stackoverflow.com/questions/1836563/how-can-i-easily-bulk-rename-files-with-perl It looks like what im looking for however, I dont know how to make a regular expression to match folders that are alphanumeric followed by a "_". All files have non-numeric names, so I think [a-zA-Z] is the right way to start. perl -e 'foreach $f (glob("File\\ Name*")) { $nf = $f; $nf =~ s/(\d+)$/sprintf("%03d",$1)/e; print `mv \"$f\" \"$nf\"`;}' Thanks for any help!

  • Where should I put my breakpoint to check XML Response string from a web service?

    - by burak ozdogan
    Hi, You know, once you add a web reference to a webservice a wrapper code is generated by Visuel Studio. I was wondering if there is a method (or property) which is generated by Visual Studio whatever web service you add to your project so that I can put a breakpoint there and once the debugger stops there, I can simply read the response from web-service in an xml format (or should I say, soap). I don't want to use fiddler or a tool like that. Is it possible? Does such a place exist in the webservice wrapper code for all the added webservice Thank you, burak ozdogan

  • IComponentActivator Instance

    - by jeffn825
    How can I use an IComponentActivator instance for a component, not just specifying a type. That is, instead of Component.For<XYZ>.Activator<MyComponentActivator>(); I want to be able say Component.For<XYZ>.Activator(new MyComponentActivator(someImportantRuntimeInfo)); Also, is there a way I can choose an activator dynamically for a non specifically registered component? That is, I want to have an activator that looks at the type being resolved, decides if it can activate it, and if not, responsibility for activation should be passed on to the default activator. So basically I want a global IComponentActivator that has the following logic: Create(Type type){ if (ShouldActivate(type)){ DoActivate(type); } else{ // do default activation here somehow } } Thanks!

  • Reverse-engineer a Javascript object?

    - by TruMan1
    I have a Javascript object that I want to pass in more parameters, but the documentation is non-existant. My only option seems to be to reverse engineer the Javascript object to see what parameters and values I can pass in. For example, I want to see if there is a "zoom" parameter for the object and what values I can pass into the "mapType" parameter: <script type="text/javascript" src="http://maps.google.com/maps?oe=utf-8&amp;file=api&amp;v=2&amp;key=your-gmap-key"></script> <script type="text/javascript" src="https://share.findmespot.com/spot-widget/js/SpotMain.js"></script> <script type="text/javascript"> var widget = new Spot.Ui.LiveWidget({ renderTo: "spot-live-widget", feeds: [ "0Wl3diTJcqqvncI6NNsoqJV5ygrFtQfBB" ], height: 400, width: 500, mapType: "physical" }); </script> <div id="spot-live-widget"/> Any ideas on how to do that?

  • How to set up an insert to a grails created file with next sequence number?

    - by Jack BeNimble
    I'm using a JMS queue to read from and insert data into a postgres table created by grails. The problem is obtaining the next sequence value. I thought I had found the solution with the following statement (by putting "DEFAULT" where the ID should go), but it's no longer working. I must have changed something, because I needed to recreate the table. What's the best way to get around this problem? ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (DEFAULT, 0, ?)"); UPDATE: In response to the suggested solution, I did the following: Added this to the the domain: class XmlTest { String xmlText static constraints = { id generator:'sequence', params:[name:'xmltest_sequence'] } } And changed the insert statement to the following: ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (nextval('xmltest_sequence'), 0, ?)"); However, when I run the statement, I get the following error: [java] 1 org.postgresql.util.PSQLException: ERROR: relation "xmltest_sequence" does not exist Any thoughts?

  • Quick way to create JSF custom component

    - by michael lucas
    I know of two ways of creating custom JSF components: 1. Native JSF way: creating JSF component class, tag, etc. 2. Facelets way: defining component in a xhtml file and then creating appropriate decrption in facelets taglib. Currently I work on a project in which introducing facelets is unfortunately out of the question. On the other hand, creating custom components the standard JSF way seems like a pain in the ass. Is there maybe a third party library that allows creating custom components in the way similar to facelets but doesn't entail the need of using non-standard renderer?

  • MySQL Student database beginner SQL employment expectations

    - by sammysmall
    Background, Student pursuing BSIT degree, employer expectations, entry level. I would like to solicit opinions from this forum as to what your professional expectations are as regards an entry level position in working in the database realm... I see many job opportunities that require a minimum of 2 or more years experience, how does one go about obtaining this experience (I have tried very hard to maintain a minimum 3.70+ GPA) but have ZERO work experience in this field... I spend non school time working in VB and SQL to try and increase my proficiency. I have considered postponing my job search until I obtain certifications from brainbench etc... Any criticism and or advise is welcomed... Again I have no experience in database other than undergrad work in class. Thank you for your time sammysmall

  • Why can't I call methods within a class that explicitly implements an interface?

    - by tyrone302
    Here's the story. I created and interface, IVehicle. I explicitly implemented the interface in my class, Vehicle.cs. Here is my interface: Interface IVehicle { int getWheel(); } here is my class: class Vehicle: IVehicle { public int IVehicle.getWheel() { return wheel; } public void printWheel() { Console.WriteLine(getWheel()); } } Notice that "getWheel()" is explicitly implemented. Now, when I try to call that method within my Vehicle class, I receive an error indicating that getWheel() does not exist in the current context. Can someone help me understand what I am doing wrong?

  • Comparison of Code Review Tools/Systems

    - by SytS
    There are a number of tools/systems available aimed at streamlining and enhancing the code review process, including: CodeStriker Review Board, code review system in use at VMWare Code Collaborator, commercial product by SmartBear Rietveld, based on Modrian, the code review system in use at Google Crucible, commercial product by Atlassian These systems all have varying feature sets, and differ in degrees of maturity and polish; the selection is a little bewildering for someone who is evaluating code review systems for the frist time. Some of these tools have already been mentioned in other questions/answers on StackOverflow, but I would like to see a more comprehensive comparison of the more popular systems, especially with respect to: integration with source control systems integration with bug tracking systems supported workflow (reviews pre/post commit, review or contiguous/non-contigous revision ranges, etc) deployment/maintenance requirements

  • Windows CE 5.0 emulator needed

    - by Heinzi
    I need an emulator for Windows CE 5.0 to test an embedded device (not PDA or smartphone) application that I am developing. This is what I have already tried: Visual Studio 2008 Pro includes an emulator. Unfortunately, it does not include a Windows CE image (only Windows Mobile and Smartphone). Yes, there is a difference, see the screenshots here. Windows CE includes a "start button", windows that can be minimized, moved around etc. There is a Windows CE Device Emulator available from Microsoft. Apart from the fact that its license only permits non-commercial use, it does not run in Windows 7 (it requires .net Framework 1.1, which is incompatible with Windows 7) nor in Windows XP mode (error message: "Emulator for Windows CE will not run one virtual machine within another. Please run the virtual machine on the host operating system"). Is there any option that I have missed?

  • GWT UIBinding cannot find zero-arg constructor

    - by aarestad
    I'm trying my hand at the new GWT 2.0 UIBinder capability, and I have a ui XML that looks like this: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:my='urn:import:com.mystuff.mypackage'> <g:VerticalPanel> <!-- other stuff --> <my:FileUploadPanel.ValidatingFileUpload styleName="field" ui:field="fileUpload" /> </g:VerticalPanel> ValidatingFileUpload is a non-static inner class contained in FileUploadPanel. It has an explicit zero-arg constructor that simply calls super(). However, when GWT starts up, I get this error: 00:00:18.359 [ERROR] Rebind result 'com.mystuff.mypackage.FileUploadPanel.ValidatingFileUpload' has no default (zero argument) constructors. java.lang.NoSuchMethodException: com.mystuff.mypackage.FileUploadPanel$ValidatingFileUpload.<init>() Any idea what might be going wrong here?

  • An approximate algorithm for finding Steiner Forest.

    - by Tadeusz A. Kadlubowski
    Hello. Consider a weighted graph G=(V,E,w). We are given a family of subsets of vertices V_i. Those sets of vertices are not necessarily disjoint. A Steiner Forest is a forest that for each subset of vertices V_i connects all of the vertices in this subset with a tree. Example: only one subset V_1 = V. In this case a Steiner forest is a spanning tree of the whole graph. Enough theory. Finding such a forest with minimal weight is difficult (NP-complete). Do you know any quicker approximate algorithm to find such a forest with non-optimal weight?

  • Accelerometer API for Laptops

    - by FreshCode
    Most IBM (and some Dell) laptops have built-in accelerometers to stop any moving parts during a sudden fall, but I was unable to find a standardised Windows API to access this data. I assume that each manufacturer would provide a driver to interface with the sensor. Which popular laptop brands come standard with accelerometers accessible from an API and which libraries should I use to access the data? Does an API* exist to abstract away the differences between different manufacturers? I am aware of the Windows 7 Sensor API, but I would like support for XP and earlier.

  • Asp.Net WriteSubsitution vs PartialView - the right way

    - by radu-negrila
    Hi, I have a partial view that should not be cached in a output cached MVC view. Usually you write non-cached content by using Response.WriteSubstitution. The problem is that WriteSubstitution takes as a parameter a HttpResponseSubstitutionCallback callback which looks like this: public delegate string HttpResponseSubstitutionCallback(System.Web.HttpContext context) This is where things get complicated since there is no easy/fun way to generate the html on the fly. You have to do a hack like this. So the question is: Is there an easier way to make a partial view not cached ?

  • PHP voting system with sessions?

    - by pingu
    Hi guys, I've been reading up on stackoverflow about creating voting systems in PHP that minimize abuse/multiple voting from the same user, but I haven't come across the answer to my question. I've got an application where users don't need to register to vote or "like" an entry. Obviously, I want to minimize abuse and I don't want to limit votes per IP address because some organisations (mine included) use shared IP addresses. I've never used sessions in a non-authenticated system before, but since this application is centered around entry votes I was wondering if this approach would work and whether there were any disadvantages such as performance implications, and whether it's even possible to use sessions in this way: start a session when the website is loaded allow one vote per item per session If this is a bad idea, my alternative options would be to allow a reasonable number of votes per IP address (say 25), or put a time limit between votes from the same IP address. What do you guys recommend?

  • Where did System.Design go?

    I am making a C# project in which I am using ScintillaNet, and it says: The referenced assembly "ScintillaNet" could not be resolved because it has a dependency on "System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project. I tried adding a reference to System.Design, but it doesn't exist in my list. Do I need to download it somewhere? I have MS Visual Studio 10.

  • Pyramid.security: Is getting user info from a database with unauthenticated_userid(request) really secure?

    - by yourfriendzak
    I'm trying to make an accesible cache of user data using Pyramid doc's "Making A “User Object” Available as a Request Attribute" example. They're using this code to return a user object to set_request_property: from pyramid.security import unauthenticated_userid def get_user(request): # the below line is just an example, use your own method of # accessing a database connection here (this could even be another # request property such as request.db, implemented using this same # pattern). dbconn = request.registry.settings['dbconn'] userid = unauthenticated_userid(request) if userid is not None: # this should return None if the user doesn't exist # in the database return dbconn['users'].query({'id':userid}) I don't understand why they're using unauthenticated_userid(request) to lookup user info from the database...isn't that insecure? That means that user might not be logged in, so why are you using that ID to get there private info from the database? Shouldn't userid = authenticated_userid(request) be used instead to make sure the user is logged in? What's the advantage of using unauthenticated_userid(request)? Please help me understand what's going on here.

  • Playing flash (.flv) videos on the web in a way that portable devices can view them

    - by Evan
    A friend of mine has created a movie for my site, it's in .flv format. I've heard of the popular flash player called flowplayer, but I have a bad feeling such a player will not work on the ipad and other devices which do not support flash. Is there a way to play a video in the flash format through a non-flash player so that the content can be viewed on all devices? I'm open to any ideas. Perhaps I may even need to convert the video to another format somehow. Thanks for any help, Evan

  • Stochastic calculus library in python

    - by LeMiz
    Hello, I am looking for a python library that would allow me to compute stochastic calculus stuff, like the (conditional) expectation of a random process I would define the diffusion. I had a look a at simpy (simpy.sourceforge.net), but it does not seem to cover my needs. This is for quick prototyping and experimentation. In java, I used with some success the (now inactive) http://martingale.berlios.de/Martingale.html library. The problem is not difficult in itself, but there is a lot non trivial, boilerplate things to do (efficient memory use, variable reduction techniques, and so on). Ideally, I would be able to write something like this (just illustrative): def my_diffusion(t, dt, past_values, world, **kwargs): W1, W2 = world.correlated_brownians_pair(correlation=kwargs['rho']) X = past_values[-1] sigma_1 = kwargs['sigma1'] sigma_2 = kwargs['sigma2'] dX = kwargs['mu'] * X * dt + sigma_1 * W1 * X * math.sqrt(dt) + sigma_2 * W2 * X * X * math.sqrt(dt) return X + dX X = RandomProcess(diffusion=my_diffusion, x0 = 1.0) print X.expectancy(T=252, dt = 1./252., N_simul= 50000, world=World(random_generator='sobol'), sigma1 = 0.3, sigma2 = 0.01, rho=-0.1) Does someone knows of something else than reimplementing it in numpy for example ?

  • Implementation of a general-purpose object structure (property bag)

    - by Thomas Wanner
    We need to implement some general-purpose object structure, much like an object in dynamic languages, that would give us a possibility of creating the whole object graph on-the-fly. This class has to be serializable and somehow user friendly. So far we have made some experiments with class derived from Dictionary<string, object> using the dot notation path to store properties and collections in the object tree. We have also find an article that implements something similar, but it doesn't seem to fit completely into our picture either. Do you know about some good implementations / libraries that deal with a similar problem or do you have any (non-trivial) ideas that could help us with our own implementation ? Also, I probably have to say that we are using .NET 3.5, so we can't take advantage of the new features in .NET 4.0 like dynamic type etc. (as far as I know it's also not possible to use any subset of it in .NET 3.5 solution).

  • Silverlight 4 accessing WCF Data Services: BeginInvoke frustrations.

    - by Gatmando
    Hi, I'm attempting to follow a pattern for performing WCF data service queries using the Silverlight 4 beta. The following is my code: public CodeTables() { CodeCountries = new ObservableCollection<dsRealHomes.CodeCountries>(); dsRealHomes.RealHomesEntities myClient = null; myClient = staticGlobals.RealHomesContext(); object userState = null; myClient.BeginExecute<dsRealHomes.CodeCountries>(new Uri("CodeCountries"), (IAsyncResult asyncResult) => { Dispatcher.BeginInvoke( () => { var test = myClient.EndExecute<dsRealHomes.CodeCountries>asyncResult).ToList(); } ); }, userState); } This is derived from a number of examples I've come across for WCF data services with silverlight. Unfortunately no matter how I try to implement the code i end up with the following error on 'Dispatcher.BeginInvoke': 'An object reference is required for the non-static field, method, or property (System.Windows.Threading.Dispatcher.BeginInvoke(System.Action)' Thanks

  • Can i use a SELECT statement to define a CHECK constraint?

    - by Neel
    In MS SQL server, can i use a SELECT statement to define a CHECK constraint? Say i have to work with two tables "Customer Master" and "Indian Customer" in ideal situation both tables are compleatly different, and are not interrelated in anyways. however they share the same database Content of "Customer Master": CustomerName (colomn): a, b, c, d, e Branchlocation (colomn): IN, AU, IN, IN, UK Content of "Indian Customer": customerID (colomn): 1, 2, 3 CustomerName (colomn): a, c, d customer details (colomn): details1, details, details . . . In Table "Indian Customer" i want to put a constraint so that the users entring data in this table should not be able to enter customers that dont exist in "Customer Master" or whose branch location is not IN. also the tables are in the same project but are not directly related.

  • When should assertions stay in production code?

    - by Carl Seleborg
    Hi all, There's a discussion going on over at comp.lang.c++.moderated about whether or not assertions, which in C++ only exist in debug builds by default, should be kept in production code or not. Obviously, each project is unique, so my question here is not so much whether assertions should be kept, but in which cases this is recommendable/not a good idea. By assertion, I mean: A run-time check that tests a condition which, when false, reveals a bug in the software. A mechanism by which the program is halted (maybe after really minimal clean-up work). I'm not necessarily talking about C or C++. My own opinion is that if you're the programmer, but don't own the data (which is the case with most commercial desktop applications), you should keep them on, because a failing asssertion shows a bug, and you should not go on with a bug, with the risk of corrupting the user's data. This forces you to test strongly before you ship, and makes bugs more visible, thus easier to spot and fix. What's your opinion/experience? Cheers, Carl See related question here
