• jQuery Autocomplete problem - Shift Key behaves same as Return Key

  - by user237005

  See: http://www.airbnb.com/ In the search bar, start typing "san f" (no quotes, all lowercase), then hit Return (or Enter). "San Francisco" is autocompleted. This is good! Now clear the search field and start over. type "San F" and boom - "San Francisco" is autocompleted as soon as you hit Shift. This is not expected. This happens in FF & Safari, but is untested elsewhere. I've looked through the jQuery Autocomplete Source Code and everything looks normal. Has anyone experienced this before?

• Is there a rake task for advancing or retreating your schema version by exactly one?

  - by user30997

  Back when migration version numbers were simply incremented as you created migrations, it was easy enough to do: rake migrate VERSION=097 rake migrate VERSION=098 rake migrate VERSION=099 rake migrate VERSION=100 ...but we now have migration numbers that are something like YYYYMMDDtimeofday. Not that this is a bad thing - it keeps the migration version collisions to a minimum - but when I have 50 migrations and want to step through them one-at-a-time, it is a hassle: rake migrate VERSION=20090129215142 rake migrate VERSION=20090129219783 ...etc. I have to have a list of all the migrations open in front of me, typing out the version numbers to advance by one. Is there anything that would have an easier syntax, like: rake migrate VERSION=NEXT or rake migrate VERSION=PREV ?

• Use of "setTimeout()" in my jQuery Expression

  - by Aaron Salazar

  I'm trying to add the JavaScript function setTimeout() to my jQuery expression. Without the setTimeout() my function loads a partial view with updated information when I enter text into my textbox. But, it loads the information with every keystroke. My logic is that if I can put in a timer then when the user stops typing, a second later the data is updated. As you can see I tried to put a setTimer() in but it doesn't seem to be working. $(function() { $('#DocId').live('keyup', function() { setTimeout(var styleValue = $(this).val(); $('#tableContent').load( '/CurReport/TableResults', { style: $(this).val()}), 1000); }), }); Thank you, Aaron

• How do you mock a Sealed class?

  - by Brett Veenstra

  Mocking sealed classes can be quite a pain. I currently favor an Adapter pattern to handle this, but something about just keeps feels weird. So, What is the best way you mock sealed classes? Java answers are more than welcome. In fact, I would anticipate that the Java community has been dealing with this longer and has a great deal to offer. But here are some of the .NET opinions: Why Duck Typing Matters for C# Develoepers Creating wrappers for sealed and other types for mocking Unit tests for WCF (and Moq)

• Keyboard layout for international programmers?

  - by splattne

  I think everybody who had to program using a standard German (or any other international) keyboard layout on Windows (or Mac) will complain about the conundrum of either having all special characters ( [ ] | { } / etc. ) needed for most programming languages "at the fingertip" and "losing" the language specific characters (umlauts ä ö ü etc.) on the keyboard or viceversa: having simple access to umlauts, but not to brackets etc. If you are programming in C / C++ / C# / Java / Javascript for example, it is very exhausting if you have to press Alt-Gr + 7 for every opening curly bracket. It is an ergonomic nightmare and reduces your typing efficiency. What is the best way to cope with this problem? Is there a satisfying solution? Maybe there are special layouts or keyboards which address this issue?

• Why does a multilanguage solution not work?

  - by Lukas

  My solution has a C# application project C# User Controls project C++ Mathematics project One of the UserControls uses function from the Mathematics (C++ project). This UserControl is used in the application. Building and starting the application works just fine. When typing the IntelliSense suggests all the contained classes and methods. The UserControl appears correctly, but on clicking a button which calls the C++ function I get a BadImageFormatException (it pops out on the end of the automatically created Main function). The help suggests to use /fixed:no for linking, but that is already set up.

• Winforms control that works like ajax tag-completion

  - by Sargola

  Heya, I want to create a winforms app where you can assign tags to an entity. ofc I want the customer to re-use existing tags a lot. That's why I want to show them the list of tags while they are typing (similar to intellisense in VS and the tags-dropdown even here in stackoverflow ;)) do you have any control(s) in mind that offers this functionality? can I reuse a ComboBox for this? (here I need to drop it down programatically - how?) I want to have the taglist getting input-focus but not lose the mainform-focus, and I want it to be on top over all windows and even range out of the mainform-area (like intellisense in vs) thx!

• Teach Perl as a first language?

  - by yossale

  I need to teach a non-programmer the basics of computer programming + some basic programming skills (- He's going to be in a position between the clients and the programmers , so the company requires him to learn the basic concepts of programming). I thought of Perl - You can teach it without getting into typing and pointers and it's syntax is very close to human (precious "bless" :) ) - but I'm a bit troubled because I feel like I'm going to "spoil" him for other languages in the future (C,C++,Java - What some people call "Real" languages) - exactly because of the reasons mentioned above. What do you think?

• Django queries: Count number of objects with FK to model instance

  - by Chris Lawlor

  This should be easy but for some reason I'm having trouble finding it. I have the following: App(models.Model): ... Release(models.Model): date = models.DateTimeField() App = models.ForeignKey(App) ... How can I query for all App objects that have at least one Release? I started typing: App.objects.all().annotate(release_count=Count('??????')).filter(release_count__gt=0) Which won't work because Count doesn't span relationships, at least as far as I can tell. BONUS: Ultimately, I'd also like to be able to sort Apps by latest release date. I'm thinking of caching the latest release date in the app to make this a little easier (and cheaper), and updating it in the Release model's save method, unless of course there is a better way. Edit: I'm using Django 1.1 - not averse to migrating to dev in anticipation of 1.2 if there is a compelling reason though.

• Ideas on collaborating with small number of people

  - by Mark Szymanski

  Hi, I am collaborating with someone on a project and currently use Skype for collaboration. I like it because we can be on a call to say things that are hard to say by typing out. We can share our screens so we can help with code writing. And we can use the text chat to copy-paste code between each other. We also use Subversion for version control. I just wanted to know what other people used for collaborating with others so I could see whats out there to use. Thanks!

• How to control allowed HTML tags in WMD Editor?

  - by Toto

  I am trying to some-how set the valid HTML tags and attributes users would be able to use in WMD Editor in my site. For example, I want to forbid the user to directly set the font size, color, typeface and so on, which is trivial to do with the default settings typing something like: <span style="font-size: 45px; color:#FF0000">Some intrusive text here</span>. I think the way to implement this is through the "wmd_options", but I have not found any documentation or reference regarding this, giving the fact that the 'Options demo' seems to be the only public documentation and it does not show how should I do what I have described above. I've send this same question to [email protected] but didn't get any reply. As stackoverflow uses this editor someone reading this or maybe Jeff knows the answer ;) Thanks in advance!

• Very unusual and weird problem with gVim 7.2

  - by Fabian

  After installing gVim and running gvim from the run window, if I were to type :cd followed by a tab, I will get \AppData, \Application Data, etc. Which basically means I'm at my $HOME directory (C:\Users\Fabian). The weird thing is I do not have a \Application Data folder there. But if I were to run gvim.exe from its installation folder, and I type :cd followed by tab, I would get \autoload, \colors, etc. which means I'm at the installation folder. And if I were to pin gvim.exe on to taskbar, upon launch and typing :cd then tab, I will get \Dictionaries and upon hitting tab again I get a beep. I think for the last scenario, I'm at some Adobe folder. Anybody knows how to fix this weird issue? I'd like to pin it to taskbar and upon launch, start in the $HOME directory (C:\Users\Fabian).

• Skip sanitization for videos in html5lib

  - by pug

  I am using a wmd-editor in django, much like this one in which I am typing. I would like to allow the users to embed videos in it. For that I am using the Markdown video extension here. The problem is that I am also sanitizing user input using html5lib sanitization and it doesn't allow object tags which are required to embed the videos. One solution could be to check the input for urls of well-known video sites and skip the sanitization in those cases. Is there a better solution?

• jList in Scrollpane, seeking and displaying value of selectedIndex

  - by Mech Software

  I have a JList inside a Scrollpane. If you click on the list and move the arrow keys up and down it works like you expect, you can move your selection index and display around just fine. Now, what I want to do is basically have a text box and i'm typing in the text box like "comic" and want it to seek to the index of that value. This WORKS just fine. Where the problem is when the value of the list box is below, or above the viewable area. When it is, the selected index seeks, but does not change the position of the scrollable region. However, if I press the up or down arrows and requestFocus() to the list, and move up and down it seeks to the right viewable area. What am I missing to make this happen WITHOUT changing focus. I want to be able to just type in the list all I want and have it show me what is selected. I feel i'm missing something obvious here.

• Way to turn on keyboard's caps-lock light without actually turning on caps-lock?

  - by cksubs

  I'm writing a program that uses caps-lock as a toggle switch. It would be nice to set the LED of the key to show that my program is on or off, like the capslock key does naturally. I know that I could just SendInput('Capslock'); or whatever to actually turn caps-lock on and off. But my app is a typing program, and I don't want to have to deal with translating the all-caps keys that turning it on would give me into their lower/upper cases. I might go that route eventually, but not for this version. I would however be interested in just turning on the LED light WITHOUT actually turning on caps-lock. Is there any way to do that? Thank you.

• Python TKinter connect variable to entry widget

  - by Sano98

  Hi everyone, I'm trying to associate a variable with a Tkinter entry widget, in a way that: Whenever I change the value (the "content") of the entry, mainly by typing something into it, the variable automatically gets assigned the value of what I've typed. Without me having to push a button "Update value " or something like that first. Whenever the variable gets changed (by some other part of the programm), I want the entry value displayed to be adjusted automatically. I believe that this could work via the textvariable. I read the example on http://effbot.org/tkinterbook/entry.htm, but it is not exactly helping me for what I have in mind. I have a feeling that there is a way of ensuring the first condition with using entry's "validate". Any ideas? Thank you for your input! Sano

• Pear SOAP and XAMPP on Ubuntu

  - by Vincent

  All, I have installed xampp for linux on ubuntu 9.10. The installation directory is /opt/lampp. The xampp website says PEAR comes with the installation.. I am relatively new to PEAR and want to know the answers for following: Is PEAR installed with xampp or need to be installed separately using synaptic package manager? I browse to /opt/lampp/bin directory and see "pear" there, but when i type it in the command line, it says "The program 'pear' is currently not installed. You can install it by typing: sudo apt-get install php-pear pear: command not found " I want to use PEAR:SOAP package in my PHP code. How to use that? Do I need to set any paths to the pear in my php.ini? Thanks

• C# .NET 4.0 and Generics

  - by Mr Snuffle

  I was wondering if anyone could tell me if this kind of behaviour is possible in C# 4.0 I have an object hierarchy I'd like to keep strongly typed. Something like this class ItemBase {} class ItemType<T> where T : ItemBase { T Base { get; set; } } class EquipmentBase : ItemBase {} class EquipmentType : ItemType<EquipmentBase> {} What I want to be able to do to have something like this ItemType item = new EquipmentType(); And I want item.Base to return type ItemBase. Basically I want to know if it's smart enough to strongly typed generic to a base class without the strong typing. Benefit of this being I can simply cast an ItemType back to an EquipmentType and get all the strongly typedness again. I may be thinking about this all wrong...

• Python lazy property decorator

  - by detly

  Recently I've gone through an existing code base and refactored a lot of instance attributes to be lazy, ie. not be initialised in the constructor but only upon first read. These attributes do not change over the lifetime of the instance, but they're a real bottleneck to calculate that first time and only really accessed for special cases. I find myself typing the following snippet of code over and over again for various attributes across various classes: class testA(object): def __init__(self): self._a = None self._b = None @property def a(self): if self._a is None: # Calculate the attribute now self._a = 7 return self._a @property def b(self): #etc Is there an existing decorator to do this already in Python that I'm simply unaware of? Or, is there a reasonably simple way to define a decorator that does this? I'm working under Python 2.5, but 2.6 answers might still be interesting if they are significantly different.

• CakePHP 1.3.0 RC4 Installation

  - by SDwebs

  I have been using 1.2.6 and downloaded 1.3 to try it out. I am using wampserver with Apache 2.2.11. I have mod rewrite enabled. When I bake a new application using the cake 1.3 console, after I verify that the webroot/index.php of the application CAKE_CORE_INCLUDE_PATH is set to the Cake1.3 Installation folder. The result is a page thats missing CSS, missing a method. Typing in localhost/app/index.php will enable the program to find the app. Therefore I have to assume the rewrite module isnt functioning properly for v1.3. Is there something I have to add to the cake installation or app folder to make this function as it should?

• What makes a bad programming language bad?

  - by sub

  We have all seen things like the typing system of JavaScript (There is a funny post including a truth table somewhere around here). I consider this one of the main things that makes a programming language bad. Other things that spring to mind: Bad Error messages (Either obfuscated so you can't figure out whats wrong, not existing or simply too long and red) The language wasn't planned and just grew uncontrolled in all directions (PHP?) The language encourages bad programm(er/ing) habits such as: Global variables everywhere, bad variable names Inconsistent naming conventions inside the language I can't come up with any more at the moment and would be very happy to read what you think about this. What shouldn't be missing in a language created to be as bad (from the perspectives of the programmer, the company that hires to programmer, the team leader and the customer) as possible? (I ask this because I'm designing a bad, experimental language at the moment)

• USB interface barcode scanners

  - by Nimbuz

  Not exactly a programming question, but close. I'll try my luck anyway. The keyboard wedge barcode scanner inserts the translation device between the reader and the keyboard. Data sent through a wedge appears as if it was typed into the computer, while the keyboard itself remains fully functional. Because a computer using a keyboard wedge can't tell the difference between data that is entered by a scanning device, or data that is entered by keyboard typing, a wedge can be used to easily add barcode reading capability to an existing computer without modifying software applications. I'd like to know if all USB interface barcode scanners automatically translate digital signals from a barcode reader into keyboard strokes for a applications just like wedge or is USB different from wedge? Many thanks

• Visual Studio autoclean?

  - by kubal5003

  Hello, I have a solution with multiple projects - executable, library, and others(unimportant right now). Library contains EF entity classes and executable uses them. When I'm working on some code from the executable then every entity that I use is marked as an error and compiler says that I should check usings and references. Reference in the executable project is set to library project(not the dll itself). When I build the library project then everything gets back to normal, but when I start typing then it happens again. I could live with it, but intelli sense isn't working and that is quite a disadvantage. Any ideas?
