• Where is the Linux source kept in a Rackspace Gentoo VPS?

  - by obvio171

  I'm emerging udev and it complains it couldn't find the kernel sources under /usr/src/linux (there's nothing inside /usr/src/ indeed). As a result, it tries to take the version from the currently running kernel and messes up thinking it's an older version than what it needs (when it actually isn't). So where are the sources so that I can properly link to them? And could I have done something wrong for them not to be in the right place?

• Having some fun - what is a good way to include a secret key functionality and fire the KeyDown event?

  - by Sisyphus

  To keep myself interested, I try to put little Easter Eggs in my projects (mostly to amuse myself). I've seen some websites where you can type a series of letters "aswzaswz" and you get a "secret function" - how would I achieve this in C#? I've assigned a "secret function" in the past by using modifier keys bool showFunThing = (Control.ModifierKeys & Keys.Control) == Keys.Control; but wanted to get a bit more secretive (without the modifier keys) I just wanted the form to detect a certain word typed without any input ... I've built a method that I think should do it: private StringBuilder _pressedKeys = new StringBuilder(); protected override void OnKeyDown(KeyEventArgs e) { const string kWord = "fun"; char letter = (char)e.KeyValue; if (!char.IsLetterOrDigit(letter)) { return; } _pressedKeys.Append(letter); if (_pressedKeys.Length == kWord.Length) { if (_pressedKeys.ToString().ToLower() == kWord) { MessageBox.Show("Fun"); _pressedKeys.Clear(); } } base.OnKeyDown(e); } Now I need to wire it up but I can't figure out how I'm supposed to raise the event in the form designer ... I've tried this: this.KeyDown +=new System.Windows.Forms.KeyEventHandler(OnKeyDown); and a couple of variations on this but I'm missing something because it won't fire (or compile). It tells me that the OnKeyDown method is expecting a certain signature but I've got other methods like this where I haven't specified arguments. I fear that I may have got myself confused so I am turning to SO for help ... anyone?

• Can I use AppDomain.AssemblyResolve Event to redirect a failed Assembly Load?

  - by esac

  By default, my application references a mixed mode DLL, so this DLL is both 32 and 64 bit. On a 32 bit system, my app is MSIL and loads the 32 bit DLL. On a 64 bit system, my app loads the 64 bit. However on a 64 bit system, in an older version of the assembly that I am referencing, they only created a 32 bit version. So I fail to load this. I was looking at doing it dynamically, and ideally I would want my MSIL app in 64 bit mode to load the 32 bit DLL. Is this possible? Also it would be nice to resolve it to a different version than what I have referenced as well. Any help appreciated.

• How can I rename by CarrierWave file versions?

  - by AKWF

  Upon the uploading of an image in my application, 4 different sizes are created and saved using CarrierWaves version functionality. However, I am converting all of these versions to JPEG. The source file that is uploaded remains unchanged. So I can upload a TIFF file, and CarrierWave will create :large, :medium, :small, and :thumb versions. My problem is that these files all still end in .tif. Yet they are indeed JPEG files, as I've verified this with the file command. How can I write the filenames correctly for each version, and ensure that CarrierWave will report each version's name correctly?

• How to display a busy message over a wpf screen

  - by dave

  Hey, I have a WPF application based on Prism4. When performing slow operations, I want to show a busy screen. I will have a large number of screens, so I'm trying to build a single solution into the framework rather than adding the busy indicator to each screen. These long running operations run in a background thread. This allows the UI to be updated (good) but does not stop the user from using the UI (bad). What I'd like to do is overlay a control with a spinning dial sort of thing and have that control cover the entire screen (the old HTML trick with DIVs). When the app is busy, the control would display thus block any further interaction as well as showing the spinny thing. To set this up, I thought I could just have my app screen in a canvas along with the spinny thing (with a greater ZIndex) then just make the spinny thing visible as required. This, however, is getting hard. Canvases do not seem well set up for this and I think I might be barking up the wrong tree. I would appreciate any help. Thanks.

• Solaris SPARC 10 32bit mode

  - by TM.

  I'm looking for a definitive answer, does Solaris 10 running on a SPARC machine support booting into 32bit mode? I've found one site that states Solaris 8 was the last version that supported booting in a 32bit mode for SPARC. I've read multiple items that explain how to boot Solaris into 32bit mode, however they did not list the Solaris version. We've tried all the ways specified, but the system keeps booting into 64bit mode.

• Radio buttons being reset in FF on cache-refresh

  - by Andrew Song

  (This is technically an addendum to an earlier StackOverflow question I had posted, but my original post asked a different question which doesn't really cover this topic -- I don't want to edit my older question as I feel this is different enough to merit its own page) While browsing my website in Firefox 3.5 (and only FF3.5), I come across a page with two radio buttons that have the following HTML code: <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/> This page renders as expected, with 'check1' checked and 'check2' unchecked. When I then go to refresh the page by pressing Control + R, the two radio buttons render, but they are both unchecked even though the raw HTML code is the same (as above). If I do a cache-miss refresh (via Control + F5 or Control + Shift + R), the page returns back to the way you'd expect it. This is not a problem in any other browser I've tried except FF3.5. What is causing these radio buttons to be reset on a normal refresh? How can I avoid this?

• How to calculate the normal of points on a 3D cubic Bézier curve given normals for its start and end points?

  - by Robert

  I'm trying to render a "3D ribbon" using a single 3D cubic Bézier curve to describe it (the width of the ribbon is some constant). The first and last control points have a normal vector associated with them (which are always perpendicular to the tangents at those points, and describe the surface normal of the ribbon at those points), and I'm trying to smoothly interpolate the normal vector over the course of the curve. For example, given a curve which forms the letter 'C', with the first and last control points both having surface normals pointing upwards, the ribbon should start flat, parallel to the ground, slowly turn, and then end flat again, facing the same way as the first control point. To do this "smoothly", it would have to face outwards half-way through the curve. At the moment (for this case), I've only been able to get all the surfaces facing upwards (and not outwards in the middle), which creates an ugly transition in the middle. It's quite hard to explain, I've attached some images below of this example with what it currently looks like (all surfaces facing upwards, sharp flip in the middle) and what it should look like (smooth transition, surfaces slowly rotate round). Silver faces represent the front, black faces the back. Incorrect, what it currently looks like: Correct, what it should look like: All I really need is to be able to calculate this "hybrid normal vector" for any point on the 3D cubic bézier curve, and I can generate the polygons no problem, but I can't work out how to get them to smoothly rotate round as depicted. Completely stuck as to how to proceed!

• Preprocess strings file during Xcode build

  - by stigi

  Hello, I know there's a way to preprocess my info.plist file, but is there a similar way to process strings files inside my Settings.bundle? My problem: I have an iPhone app and I want the the user to know about the currently installed version. I do this by displaying it in the apps settings. Now every time i change the bundle version in my info.plist i also have to change the version in the Root.strings in the Settings.bundle. I could run a script action that updates it, but it would be nice to use the preprocessor since I could do even more fun things with it. Thanks!

• Can folks that edit tags make sure they preserve the information that they would be editing away?

  - by vkraemer

  I have notice that some folks edit the tags associated with questions to make the tag more generic, like converting netbeans6.8-netbeans. I think this is a good thing. BUT, most users/askers do not include version info in the text of their question and some of them do pick the 'versioned' tag. That additional info is valuable at that point. Please read the question before you edit version info out of tags. If the version info is not in the question's text.... take another moment to edit the text of the question, so the info is immediately available to folks that are trying to answer questions.

• Subdomains, folders, internationalization, and hosting solutions

  - by justinbach

  I'm a web developer and I recently landed a gig to develop the US / international version of a site for a company that's big in Europe but hasn't done much expansion into the US yet. They've got an existing site at company.com, which should remain visible to European customers after the new site goes up, and an existing (not great) site at company.us, which I'm going to be redeveloping (the .us site will be taken down when my version goes up--keep reading for details). My solution needs to take into account the fact that there are going to be new, localized versions of the site in the fairly near future, so the framework I'm writing needs to be able to handle localizations fairly easily (dynamically load language packs, etc). The tricky thing is the European branch of the company manages the .com site hosting (IIS-based) and the DNS, while I'll be managing the US hosting (and future localizations), which will likely be apache-based. I've never been a big fan of the ".us" TLD--I think most US users are accustomed to visiting the .com--so the thought is that the European branch will detect the IP of inbound traffic and redirect all US-based addresses to us.example.com (or whatever the appropriate localized subdomain might be), which would point to the IP address of my host. I'd then serve the appropriate locale-specific content by pulling the subdomain from the $_SERVER superglobal (assuming PHP). I couldn't find any examples of international organizations that take a subdomain-based approach for localization, but I'm not sure I have any other options as a result of the unique hosting structure here (in that there's not a unified hosting solution for the European and US sites). In my experience, the US version of an international site would live at domain.com/us, not at us.domain.com, and I'd imagine that this has to do with SEO (subdomains are treated as separate sites, so improved rankings for the US site wouldn't help the Canadian version if subdomains are used to differentiate between them). My question is: is there a better approach to solving this problem than the one I'm taking? Ideally, I'd like to use a folder-based approach (see adidas.com as an example of what I'm talking about), but I'm not sure that's a possibility given that the US site (and other localizations) will not be hosted on the same server as the rest of the .com. Can you, in IIS, map a folder (e.g. domain.com/us) to a different IP address? What would you recommend? Thanks for your consideration.

• Silverlight ClientAccessPolicy issue...I think

  - by Terrence

  Fisrt of all I have my ClientAccessPolicy.xml file in the root of my website. If I access my website using the public domain name like this: h t t p://www.mydomain.com and then go to the page where my SL control is, I get the spinning % numbers up until about 98%, then it quits and my SL control does not appear on the page. If I access my website using the machine name (website is at datacenter, we have vpn setup) like this: h t t p://machinename and then go to the page where my SL control is everything works fine. this must be a ClientAccess Policy issue don't your think? Or what DO you thnik the issue is? Thanks in advance. Here is the contents of my ClientAccessPolicy.xml file: <?xml version="1.0" encoding="utf-8" ?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*" /> </allow-from> <grant-to> <resource path="/" include-subpaths="true" /> </grant-to> </policy> </cross-domain-access> </access-policy>

• Where can I find a suitable replacement for an expired SPSS 18 trial in OSX?

  - by Telos

  A friend of mine needs to use SPSS for a project she is working on, and would normally have access to it in her school's library. Unfortunately she's out of town for the next couple weeks, and she's already gone through the trial version once. Her idea is to install a trial for an earlier version (like SPSS 17 instead of 18) but we're not sure where she would find that either. Any thoughts on how to get her up and running?

• Revert Skype contact list to be like it was before the latest update

  - by mickburkejnr

  My Skype client has been updated to the latest version (on Windows 7). In the new version it's grouped all my Facebook contacts in along with my normal Skype contacts. I've tried to get used to it but it's being an absolute pain when you start a conversation with a contact, only to find your speaking to them through their Facebook account and not their Skype. Is there any way I can revert my Skype client to split the Skype contacts from the Facebook contacts like it was before this update?

• ScriptManager duplicates javascript

  - by Andreas

  Hi! I have a usercontrol that can be used in for example a gridview itemtemplate, this means that the control might or might not be on the page at page load. In the case where the control is inside an itemtemplate i will popupate the gridview via asyncronous postbacks (via updatepanels). The control itselfs registrers scriptblocks since it is depending on javascripts. First i used Page.ClientScript.RegistrerClientScriptBlock But this doesn't work on asyncronous postbacks (updatepanels) so i then tried the same using ScriptManager which allows me to registrer scripts on the page after async postbacks. great!. ScriptManager.RegisterClientScriptBlock However, ScriptManager (what i know of) does not have the functionallity to see if a script already is on the page, so i will for every postback generate duplicates of the script blocks, this is ofcourse unwanted behaviour. I did a run at Google and found that i can call the Dispose() method of the PageRequestManager can be used, this does work since it clears the scripts and then adding them again (this also solves my issue with removing unused script blocks from removed controls). Sys.WebForms.PageRequestManager.getInstance().Dispose() However, ofcourse there is a downside since im posting here :). The Dispose() method disposes the instance on the master page as well which leads to scripts running there will stop to function after an async postback (updateprogress for example). So, is there a way to check if a script already exists on the page using ScriptManager or any other tools, that will prevent me of inserting duplicate scripts? Also, is there a way to remove certain script blocks (when i am removing an item in itemtemplate for example). Big thanks in advance.

• How hard is it for a .NET programmer to learn Objective C and Cocoa?

  - by rsteckly

  Hi, I'm trying to build a dual platform application for a company of my own I'm trying to start at night. I have the .NET version done, but have not finished the UI part. I'm thinking of buying some 3rd party controls. If I buy these controls, however, they clearly will only work in my Windows version. I'm wondering if I should try to do the UI in GTK# and use Mono with CocoaSharp or just build the thing in MS technology and teach myself the Mac side? I'm just really unfamiliar with the Mac world and am wondering how much of a learning curve there might be. I've thought perhaps of rewriting my core logic in Ruby or Python. This why I could use the .NET version with .NET controls and presumably hook the same code up on the Mac. It's an educational app targeted at consumers. As such, it shouldn't require a lot of technical sophistication to install.

• CUDA driver installation on a laptop with nVidia NVS140M card

  - by stanigator

  I'm trying to first figure out if my computer contains a CUDA-enabled card. It has an nVidia NVS 140M card, but I can't seem to figure out if it is the 128 MB version or 256 MB version. On the laptop purchase receipt, I found out that I ordered the 128 MB version, but the control panel description of the card said otherwise as shown below: When I ran the CUDA driver from nVidia's site, it cannot find a hardware compatible with CUDA (even though the product series is CUDA-enabled, the card does not have 256 MB minimum of memory to do so). What would be your recommendations in this case with trying to use CUDA on this computer (I'm not sure if nothing can be done at this point)? Thanks in advance.

I want to get a call in number based in England and was wondering if receiving calls via the call in number on my mobile via wifi would use any of my callout credit? I ask because the Skype lite version uses your callout credit if you receive a call on it using your online number (it doesn't if you use the desktop version). Thanks!
