  • Profiling tool for Clojure?

    - by j-g-faustus
    Hi, does anyone know of a good profiling tool or library for Clojure? I would prefer something that could be used from the REPL, along the lines of (with-profiling ...) in Allegro Common Lisp back in the day. Is there anything along those lines? Or do you have any experience with (non-commercial) Java profilers that work well with Clojure?

  • License for website article

    - by queueoverflow
    On my personal website, I have some technical ideas and some source code snippets that I share with everybody. To make it clean that everyone can use those snippets as they like, as long as I do not have to provide any warranty, I would like to add a license to the some of the texts. The bigger programs come with GPLv2+, which I think is a reasonable license for free code. Does it make sense to use the MIT License or the GNU Free Documentation License for these texts or should I just go with CC-BY? I am a German citizen, so I heard that the American licenses do not really apply to me at all. If so, that would be another advantage for the Creative Commons Family of License.

  • Integration Services Throws an Error Reading Access 2007 Table

    - by Eric Flamm
    [Participant Table [1994]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "I:\My Documents\Flamm Consulting\Migrations.accdb" failed with error code 0xC0209303. There may be error messages posted before this with more information on why the AcquireConnection method call failed. Frankly, I'm confused about how SSIS should connect to Access 2007 - the UI just isn't very friendly - there's no file browser, for example. I'm wondering if there's something wrong with my install - missing drivers, etc.

  • How Netbeans Editors know that file is not modified after undo?

    - by Ha
    Netbeans uses standart UndoManager API for implementation of undo functionality. But neither standart javax.swing.undo.UndoManager nor org.openide.awt.UndoRedo.Manager doesn't have any method to mark states as saved and check modified status. Nonetheless if you change the file and press undo, the file is marked as unmodified. How do they do that? I need the same functionality for my (non-text) editors if the Netbeans RCP application.

  • Simplest way to host a domain name just so i can forward it to a wordpress blog?

    - by Max Williams
    Hi all. I have a domain name, and a wordpress account. The domain name isn't hosted anywhere at the moment. I just want to set it up so that my wordpress blog uses the domain. According to the wordpress help page on this issue, i have to do the following: Update your domain’s name servers to the following. Make sure to remove any existing name servers that are already there. NS1.WORDPRESS.COM NS2.WORDPRESS.COM NS3.WORDPRESS.COM So, this is the only thing that i need a server for - if i even need a server at all? Is there a really simple way i can do this for free? Or for very cheap? I'm a bit ignorant about this stuff: i do rails coding but don't get involved in the really technical stuff to do with servers and dns and what have you.

  • Changing keyboard layout on application focus

    - by Anonymous Coward
    Hi Everyone As everybody knows the en-US Keyboard-layout is the best one for programming. So I'd like to use it in my IDEs. But since I live in a non-en-US country I need the de-CH layout for all other applications. Now I wonder if it is possible to set the layout depending to which application currently has the focus. If that is possible, can a human brain adapt to such a behaviour or is it just confusing? cheers, AC

  • How can I disable a model field in a django form

    - by jammon
    I have a model like this: class MyModel(models.Model): REGULAR = 1 PREMIUM = 2 STATUS_CHOICES = ((REGULAR, "regular"), (PREMIUM, "premium")) name = models.CharField(max_length=30) status = models.IntegerField(choices = STATUS_CHOICES, default = REGULAR) class MyForm(forms.ModelForm): class Meta: model = models.MyModel In a view I initialize one field and try to make it non-editable: myform = MyForm(initial = {'status': requested_status}) myform.fields['status'].editable = False But the user can still change that field. What's the real way to accomplish what I'm after?

  • Set Up Remote Desktop at Home

    - by Rev
    I'm sure this has been asked before, but I'm unable to find a clear set of instructions. I'm currently using LogMeIn Hamachi to enable Windows 8's Remote Desktop feature on my home computer (running Win8 Pro x64). Unfortunatley, I can't use this method to access my home computer from my Surface Tablet, as I can't install in the Hamachi client. So how can I set up Remote Desktop without using LogMeIn Hamachi? A link to a noob-friendly tutorial would be greatly appreciated. I haven't been able to find anything that I understand (and I am pretty technical, router stuff just stumps me for some reason). EDIT: And I don't want to use a third party service like TeamViewer, in my experience those tools are laggy and quite horrible. The Remote Desktop feature has been excellent.

  • How can I identify whether a browser/reader is being used by someone who is visually impaired?

    - by Mark Brittingham
    I have to provide a 508-compliant version of a page for the visually impaired and it isn't practical to just modify the page. Thus, I have created a new "reader-compatible" version of the page for the handicapped. The question is how I can tell if someone is using a reader rather than a standard browser? Is there a "header" or "useragent" value typically used by these non-standard browsers that I can look for? Thanks in advance!

  • Why is the Objective-C Boolean data type defined as a signed char?

    - by EddieCatflap
    Something that has piqued my interest is Objective-C's BOOL type definition. Why is it defined as a signed char (which could cause unexpected behaviour if a value greater than 1 byte in length is assigned to it) rather than as an int, as C does (much less margin for error: a zero value is false, a non-zero value is true)? The only reason I can think of is the Objective-C designers micro-optimising storage because the char will use less memory than the int. Please can someone enlighten me?

  • Why no Win16 support in 64-bit Windows?

    - by dsimcha
    My understanding (from Wikipedia) is that the x64 instruction set supports executing 16-bit protected mode code from long mode, but cannot execute real mode code without being switched out of long mode because long mode lacks virtual 8086 mode. Therefore, it stands to reason that real mode DOS apps can't be run in Win64 w/o software emulation or dynamic translation. However, why was support for Win16 protected-mode apps excluded when support for them seems (at least at first glance) to be reasonably implementable and is included in newer versions of Win32? Was it just a matter of demand not being high enough to justify implementation costs (and the win32 version was already implemented), or is there a good technical reason?

  • How do I create a clicked state in a SIlverlight button?

    - by Roy
    How do I create a clicked state in visual state manager for a control that is based on a button control? I tried using a pressed state but once the mouse button is released it reverts back to the original color. I would like to change the color of the button when it is clicked on. I am not looking for a solution in the click event handler because this is a part of a template. Thank you

  • Sinatra/Rails: Persisting custom class instances during app lifetime

    - by knoopx
    Can I assert rails/sinatra apps are initialized only once and all requests share the same app instance? or do new requests spawn new app instances? Is it possible to instance custom classes and persist them during app lifetime without using sessions, database storages or third party services? If so, what are the implications from a thread-safeness point of view? I'm trying to figure how to implement a web-based download manager and I'm currently evaluating ruby-based frameworks.

  • More than one XP Mode virtual machines okay under Win 7?

    - by kousen
    I really like the Windows XP Mode virtual machine that comes with Windows 7 (once you download the integration components). I teach technical training classes, and having a machine configured for the classroom is very helpful. My question is, can I configure more than one? The documentation suggests you can make multiple virtual machines, but I can't tell if I can have multiple "Windows XP Mode" VMs. It can't be as simple as configuring one, then just making a copy of the primary disk file, could it? I only plan to run one at a time, but I'd like to configure multiple different VMs for different classes, all running XP if possible. Thanks for any help!

  • Is it OK to try to use Plinq in all Linq queries?

    - by Tony_Henrich
    I read that PLinq will automatically use non parallel Linq if it finds PLinq to be more expensive. So I figured then why not use PLinq for everything (when possible) and let the runtime decide which one to use. The apps will be deployed to multicore servers and I am OK to develop a little more code to deal with parallelism. What are the pitfalls of using plinq as a default?

  • PHP preg_replace - Very quick question

    - by RC
    Masters of regular expressions, please help! See this string: $string = "http://www.url.com/?fieldA=123&fieldB=456&fieldC=789"; Assuming "fieldB" always has a positive non-decimal numerical value (but not necessarily three digits long), what preg_replace command do I need to remove it completely, such that the string will then read: $string = "http://www.url.com/?fieldA=123&fieldC=789"; Thanks!
