  • .NET equivalent to Perl regular expressions

    - by r_honey
    I need to convert a Perl script to VB.NET. I have managed almost the entire conversion, but some Perl (seemingly simple) regex are causing an headache. Can someone suggest me .NET equivalent of the following perl regex: 1) $letter =~ s/Users //,; $letter =~ s/Mailboxes //,; if($letter =~ m/$first_char/i){ 2) unless($storegroup =~ /Recovery/ || $storegroup =~ /Users U V W X Y Z/ || $storegroup =~ /Users S T/ || $storegroup =~ /Users Q R/){ The regex look simple to me. I tried to wade through perl.org but understanding a langugae regex takes sometime and I need to complete the conversion quickly.

  • Choose a local file w/o uploading the chosen file

    - by Austin Hyde
    I am making a simple development tool for myself using PHP on my local development server. I would like a way to have a simple file-chooser to select a file without uploading it, but just retaining the file path. This is useful, because I will be the only one using the tool, and so PHP will have access to the chosen file without having it uploaded. My first thought is to have a <input type="file"...>, but as far as I know, there's no way to prevent the upload from happening. Is there a way to do this?

  • Running Awk command on a cluster

    - by alex
    How do you execute a Unix shell command (awk script, a pipe etc) on a cluster in parallel (step 1) and collect the results back to a central node (step 2) Hadoop seems to be a huge overkill with its 600k LOC and its performance is terrible (takes minutes just to initialize the job) i don't need shared memory, or - something like MPI/openMP as i dont need to synchronize or share anything, don't need a distributed VM or anything as complex Google's SawZall seems to work only with Google proprietary MapReduce API some distributed shell packages i found failed to compile, but there must be a simple way to run a data-centric batch job on a cluster, something as close as possible to native OS, may be using unix RPC calls i liked rsync simplicity but it seem to update remote notes sequentially, and you cant use it for executing scripts as afar as i know switching to Plan 9 or some other network oriented OS looks like another overkill i'm looking for a simple, distributed way to run awk scripts or similar - as close as possible to data with a minimal initialization overhead, in a nothing-shared, nothing-synchronized fashion Thanks Alex

  • Python Framework for small website

    - by mvid
    I am planning a small, simple website to showcase myself as an engineer. My preferred language is Python and I hope to use it to create my website. My pages will be mostly static, with some database stored posts/links. The site will be simple, but I would like to have freedom in how it operates. I plan on using CSS/JS for the design, so I really just need an easy way to throw a small amount of content around. Some frameworks I have come across: Flask cherry.py Pinax Are there any suggestions? Does anyone have any experience with Python on small/hobby websites?

  • Are there any serialization frameworks for java

    - by Grofit
    I know there is simple, which seems to be a decent enough XML serializer and i know there is Jaxb which seems to do the job as well. However im after something a bit more generic, so I could serialize my model to Xml, Json, Binary etc. So the models are just dumb objects that just get thrown into some sort of serialization factory and then the relevant output is spat out... I dont see any reason why you couldn't do this with reflection, so for a REALLY simple solution get the relevent public properties, cut off the get or set and make that the element name... i.e getPersonName() would become <PersonName>xxxx</PersonName> or PersonName:XXXXX

  • Have problems designing input and output for a calculator app

    - by zoul
    Hello! I am writing a button calculator. I have the code split into model, view and a controller. The model knows nothing about formatting, it is only concerned with numbers. All formatting is done in the view. The model gets its input as keypresses, each keypress is a part of an enum: typedef enum { kButtonUnknown = 0, kButtonMemoryClear = 100, kButtonMemoryPlus = 112, kButtonMemoryMinus = 109, kButtonMemoryRecall = 114, kButtonClear = 99, … }; When the user presses a button (say 1), the model receives a button code (kButtonNum1), adds the corresponding number to a string input buffer ("1") and updates the numeric output value (1.0). The controller then passes the numeric output value to the view that formats it (1). This is all plain, simple and clean, but does not really work. The problem is that when user enters a part of a number (say 0.00, going to enter 0.001), the input does not survive the way through model to view and the display says 0 instead of 0.00. I know why this happens ("0.00"::string parses to 0::double and that gets formatted as 0). What I don’t know is how to design the calculator so that the code stays clean and simple and the numbers will show up on screen exactly as the user types them. I’ve already come with some kind of solution, but that’s essentially a hack and breaks the beautiful and simple flow from the calculator model to the display. Ideas? Current solution keeps track of the calculator state. If the calculator is building a number, I take the calculator input buffer (a string) and directly set the display contents (also a string). Otherwise I take the proper path, ie. take the numeric calculator output, pass it to the view as a double and the view uses its internal formatter to create a string for the display. Example input: input | display | mode ------+---------+------------ 0 | 0 | from string 0. | 0. | from string 0.0 | 0.0 | from string 0.0+ | 0 | from number This is ugly. (1) The calculator has to expose its input buffer and state. (2) The view has to expose its display and allow setting its contents directly using a string. (3) I have to duplicate some of the formatting code to format the string I got from the calculator input buffer. If user enters 12345.000, I have to display 12,345.000 and therefore I’ve got to have a commification code for strings. Yuck.

  • Android process killer

    - by Martin
    I have similar question, maybe you can help. Is it possible to get list of all process which are running in the Android system, and kill some of them? I know that there are some applications (task managers), but I would like to write my own, simple application. I would like to write simple task manager, just list of all process and button which will kill some of them. Could you just write some Java methods which I can call in order to get list of process, and method for killing them. Or just give me some advices. Thanks for answers. Regards Martin

  • Get "As low as" price for bundle product in Magento

    - by dardub
    I'm trying to display a list of bundled products using my custom template. I'm not able to display the dynamic price of the bundle product. Previously for simple products I used: $product->getPrice(); which worked, but it just displays $0.00 for bundle items. looking at ../catalog/products/list.phtml I tried $this->$getPriceHtml($product, true); after extending my block to Mage_Catalog_Block_Product_Abstract I got simple products working again, but bundle products still show $0.00 Is there another way to display the as low as price for dynamic bundle prices? I cleared cache and reindexed and all that good stuff. The price shows up correctly under the default category list, just not under my custom page.

  • PHP - a different open_basedir per each virtual host

    - by Lopoc
    Hi I've came across on this problem, I have a sever running apache and php. We have many virtual hosts but we've noticed that a potentially malicious user could use his web space to browse other user's files(via a simple php script) and even system files, this could happens due to the php permissions. A way to avoid it is to set the open_basedir var in php.ini, yhis is very simple in a single host system, but in case of virtual hosts there would be a basebir per each host. Ho can I set dis basedir per each user/host? is there a way to let apache hereditate php privileges of the php file that has been requested E.G. /home/X_USER/index.php has as owner X_USER, when apache read the file index.php it checks its path and owner, simply I'm looking for a system set php basedir variable to that path. Thank in advance Lopoc

  • DataBinding a DropDownList in ASP.NET MVC 2

    - by Daniel Coffman
    I'm extremely frustrated trying to switch to MVC after a couple years of webforms development. Here's my extremely simple problem that I can't manage to solve: I have a list of States in a table called StateProvince. I have a DropDownList. I want the DropDownList to display all of the States in the StateProvince table and post the selected state back on HTTP PUT. This is what I'm doing: <%: Html.DropDownListFor(model = model.StateProvinceId, new SelectList(Model.StateProvinces, "StateProvinceId", "Name") )% I'm getting an Object reference not set to an instance of an object. Why? How can I make this work? Keep it simple, I know nothing about MVC.

  • MATLAB for kids?

    - by yuk
    My seven-years old expresses large interest in computers (well, who doesn't? :). Since I'm mostly program in MATLAB, I'm thinking why not to teach him MATLAB. We did a small project with him (he had to solve as many simple arithmetic problems as possible in a limited time) and he get pretty excited. I coded, he watched and then tested. He also likes to do create interesting graphics and simple animations. So, what's next? I would appreciate any ideas for interesting projects, games, graphics? What math concepts he has to understand to program in MATLAB? Or may be you would say it's too early and we should start with something like Logo, Scratch or Alice?

  • set label value in vb.net

    - by julio
    Hi-- I'm usually a PHP guy but got stuck doing a project in vb.net. I have a query (sqldatasource) that returns a single value (the last update date). I want to use a label to say something like "Last updated: " < Label = (returned value) In PHP this would be simple. In vb.net, all I can find are endless badly written code behinds showing how you'd execute the query onLoad then bind it to the label. Is this really the only way to do this? It seems like a ridiculously simple problem to have such a long solution. I have used a datagrid control to just bind the query result directly, but it prints the column name as well as the date, so it's not ideal. Any ideas?

  • Any good Open Source or Cheap ASP.NET Catalog Applications

    - by Zhaph - Ben Duguid
    We're looking for a cheap-to-free "off the shelf" ASP.NET catalogue application, that will meet the following requirements: Support two kinds of listings: Suppliers of Services Suppliers of Products, and their Products Suppliers can be categorised by: Area of specialisation - including sub-categories Location Other data, e.g. where listing came from Versioning of supplier/product details Easy to use management interface Use masterpages so we can drop it into our existing site layout Run on a Windows 2003 server, with .NET 3.5 installed In an ideal world, the following additional requirements might be met: Suppliers can manage their own listings Other products that are available to us (that will obviously need some additional development to meet these requirements) are: Content Management System (MS) Commerce Server - bear in mind we're not selling the products/suppliers, just listing them Simple DB application. I'm happy to knock something up in MCMS/simple DB, I'm just looking to see if anyone's had any experience with off the shelf apps that could save us some time. I'm also happy to receive "Don't use this because" type answers. Thanks.

  • Django: test failing on a view with @login_required

    - by Esteban Feldman
    Hi all, I'm trying to build a test for a view that's decorated with @login_required, since I failed to make it work, I did a simple test and still can't make it pass. Here is the code for the simple test and the view: def test_login(self): user = self._create_new_user() self.assertTrue(user.is_active) login = self.client.login(username=user.username, password=self.data['password1']) self.failUnless(login, 'Could not log in') response = self.client.get('/accounts/testlogin/') self.assertEqual(response.status_code, 200) @login_required def testlogin(request): print 'testlogin !! ' return HttpResponse('OK') _create_new_user() is saving the user and there is a test inside that method to see that is working. The test fails in the response.status_code, returning 302 and the response instance is of a HttpResponseRedirect, is redirecting it as if not logged in. Any clue? I'm missing something? Regards Esteban

  • How to reduce compilation times with Boost Asio

    - by Artyom
    Boost.Asio is great library but it has one huge drawback -- extreamly slow compilation times. A simple implementation (really simple) of HTTP protocol (about 1k lines of code) requires about 13.5s to compile under GCC 4.4! I tryed to use PCH but it does not improve compilation times too much (about 1s. only). So are there any tutorials on how to make Boost.Asio compilation times faster? For example what headers should I exactly include for what class. I use for example: io_service, tcp::ip::sockets, tcp::ip::acceptor, deadline_timer, buffers and few functions like async_read, async_write. Any suggestions? P.S.: I do use pimpl whenever I can.

  • Adding links to full change forms for inline items in django admin?

    - by David Eyk
    I have a standard admin change form for an object, with the usual StackedInline forms for a ForeignKey relationship. I would like to be able to link each inline item to its corresponding full-sized change form, as the inline item has inlined items of its own, and I can't nest them. I've tried everything from custom widgets to custom templates, and can't make anything work. So far, the "solutions" I've seen in the form of snippets just plain don't seem to work for inlines. I'm getting ready to try some DOM hacking with jQuery just to get it working and move on. I hope I must be missing something very simple, as this seems like such a simple task! Using Django 1.2.

  • Gradle java.util.logging.Logger output in unit tests

    - by Misha Koshelev
    Dear All: Sorry this is probably a very simple question. I am using gradle http://www.gradle.org/ for my development environment. It works quite well! I have written a simple unit test that uses HtmlUnit and my own package. For my own package, I use java.util.Logger. HtmlUnit seems to use commons logging: http://htmlunit.sourceforge.net/logging.html I would like to see console output of my logging messages from java.util.Logger However, it seems that even messages at the info level are not displayed in my Unit Test Results GUI (System.err link), although the HtmlUnit messages are all displayed. Please let me know if you have suggestions. Thank you! Misha
