  • "Share on LinkedIn" widget chokes on encoded spaces in url param

    - by David Droddy
    Does anyone know why I am not able to include my own, URL encoded URL params with URL encoded spaces? See the URL on my jsBin page constructed from LinkedIn's example--I have added (%3FnestedParam%3Done%20space) at the end of the "URL" value. THEN, if you remove the encoded space (%3FnestedParam%3DoneSpace) it works fine: Try it out: http://jsbin.com/acosa3/3 Thanks!

  • Xml with spaces as InnerText

    - by David Rutten
    I'm parsing Xml data which has entries like this: <item name="UserText" type_name="gh_string" type_code="10"> </item> I'm supposed to read the 6 spaces as a String, but both the InnerText and InnerXml values of the System.Xml.XmlNode are zero length Strings. Is there any way I can get at this whitespace data in existing files and what do I need to do in the future to prevent this sort of screw up?

  • Remove all arbitary spaces before a line in Vim

    - by Farslan
    I'v written a plugin where it comes to parsing a XML tag. The content inside the tag is indented and when i copy the parsed string into the file it's gettting like: Example line This is part of the parsed line Thats goes one End of line What I want is to remove all spaces in front of these lines, the final text should be Example line This is part of the parsed line Thats goes one End of line I've tried to use = but it doesn't work the way U want. How can I do that with minimal key strokes ?

  • handling filename* parameters with spaces via RFC 5987 results in '+' in filenames

    - by Peter Friend
    I have some legacy code I am dealing with (so no I can't just use a URL with an encoded filename component) that allows a user to download a file from our website. Since our filenames are often in many different languages they are all stored as UTF-8. I wrote some code to handle the RFC5987 conversion to a proper filename* parameter. This works great until I have a filename with non-ascii characters and spaces. Per RFC, the space character is not part of attr_char so it gets encoded as %20. I have new versions of Chrome as well as Firefox and they are all converting to %20 to + on download. I have tried not encoding the space and putting the encoded filename in quotes and get the same result. I have sniffed the response coming from the server to verify that the servlet container wasn't mucking with my headers and they look correct to me. The RFC even has examples that contain %20. Am I missing something, or do all of these browsers have a bug related to this? Many thanks in advance. The code I use to encode the filename is below. Peter public static boolean bcsrch(final char[] chars, final char c) { final int len = chars.length; int base = 0; int last = len - 1; /* Last element in table */ int p; while (last >= base) { p = base + ((last - base) >> 1); if (c == chars[p]) return true; /* Key found */ else if (c < chars[p]) last = p - 1; else base = p + 1; } return false; /* Key not found */ } public static String rfc5987_encode(final String s) { final int len = s.length(); final StringBuilder sb = new StringBuilder(len << 1); final char[] digits = {'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'}; final char[] attr_char = {'!','#','$','&','\'','+','-','.','0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z','^','_','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','|', '~'}; for (int i = 0; i < len; ++i) { final char c = s.charAt(i); if (bcsrch(attr_char, c)) sb.append(c); else { final char[] encoded = {'%', 0, 0}; encoded[1] = digits[0x0f & (c >>> 4)]; encoded[2] = digits[c & 0x0f]; sb.append(encoded); } } return sb.toString(); } Update Here is a screen shot of the download dialog I get for a file with Chinese characters with spaces as mentioned in my comment.

  • Wordpress Multisite- How to restrict a non-wordpress page only to one domain

    - by yibe
    I am running three blogs from a wordpress multisite. Currently, I am developing a separate, non wordpress application. I want to link this application with blog1. I put the application in the subfoler of my root directory (The Wordpress multisite is installed in the root). I linked the application in the menu of blog1. So far so good. But, it is possible to access the application from all the three blogs. I want the application to be accessible only from blog1-domain/my-app/ but when I tried blog2-domain/my-app, it just opened normally. Generally, the application is accessible from all the three domains followed by /my-app. I don't think it is proper to go this way. Then, what can I do to restrict my app to be accessible only from a my blog1-domain/my-app ? Or am I not using a good blog structure?. I am open to all kind of suggestions. Thank you for your help.

  • Ruby Shoes for non-trivial apps

    - by marcof
    I've been taking a look at Ruby Shoes for GUI development with Ruby. So far, it's been a pretty good experience for making simple apps. However, I am quite worried about being able to write large scale applications with it. For example, how would I go about using MVP pattern with this framework ? For now, I have not been able to not make presentation concerns leak into the view because of the lack of some kind of "data binding". I have code that looks like this : Shoes.app do @view = SampleView.new @presenter = SamplePresenter.new @view @label = para @view.sample_property button "Update sample_property" do @presenter.update_sample_property end end Here, the call to @presenter.update_sample_property updates @view.sample_property but the label is not updated accordingly. For this to work, I would have to make @presenter.update_sample_property to return a string, and then call @label.text = return_value, but I think that would violate the MVP principle of not having presentation logic in the view. I'm used to work in .Net with the MVP pattern so I don't know if the pattern applies correctly to Shoes like I tried to do. Are there any ressources out there for making non-trivial apps with Shoes ? Especially using the MVP pattern or something similar ? EDIT : I took a look at the shoebox to see what other people have achieved with the framework. Though I did not look through it extensively, at first sight it seems like they are all simple projects with no real purposes.

  • Encrypting a non-linux partition with LUKS.

    - by linuxn00b
    I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?

  • Running Non-profit Web Applications on Cloud/Dedicated Hosting [closed]

    - by cillosis
    Possible Duplicate: How to find web hosting that meets my requirements? I often times build web applications purely because I enjoy it. I like building useful tools or open source applications that don't come with a price tag. That being said, many of these applications can be quite complex requiring services beyond shared hosting (ex. specific PHP extensions). This leaves me with two options: Make the web application less complex and run on shared hosting. Fork out money for cloud or dedicated/VPS hosting. Considering the application is free (I don't make money off of it intentionally), the money for hosting comes out of my own pocket. I know I am not alone in this sticky situation. So the question is, what are the hosting options that provide more advanced features such as shell access via SSH, ability to install specific software/extensions (ex. if I wish to use a NoSQL DB such as Redis, MongoDB, or Cassandra), etc., at a free or low price point? I know free usually equates to bad/unreliable hosting -- but it's not always the case. There are a couple providers with free plans I know of: Amazon EC2 - Free micro-instance for 1 year AppHarbor - Cloud based .NET web application hosting w/ free plan. What else is available for hosting of non-profit applications?

  • Combo/Input LOV displaying non-reference key value

    - by [email protected]
    Its a very common use-case of LOV that we want to diplay a non key value in the LOV but store the key value in the DB. I had to do the same in a sample application I was building. During implementation of this, I realized that there are multiple ways to achieve this.I am going to describe each of these below.Example : Lets take an example of our classic HR schema. I have 2 tables Employee and Department where Dno is the foreign key attribute in Employee that references Department table.I want to create a LOV for Deparment such that the List always displays Dname instead of Dno. However when I update it, it it should update the reference key Dno.To achieve this I had 3 alternative1) Approach 1 :Create a composite VO and add the attributes from Department into Employee using a join.Refer the blog http://andrejusb.blogspot.com/2009/11/defining-lov-on-reference-attribute-in.htmlPositives :1. Easy to implement and use.2. We can use this attribute directly in queries defined on new attribute i.e If i have to display this inside query panel.Negative : We have to create an additional Join on the VO.Ex:SELECT Employees.EMPLOYEE_ID,        Employees.FIRST_NAME,        Employees.LAST_NAME,        Employees.EMAIL,        Employees.PHONE_NUMBER,       Department.Dno,        Department.DnameFROM EMPLOYEES Employees, Department Department WHERE Employees.Dno = Department .Dno2) Approach 2 :

  • Are there opportunities working as full-time paid programmer for Non-profit organizations

    - by Rick
    Some recent events in my life have made me want to contribute more to causes I believe in rather than just working for a profit-driven company. I have been thinking that if I could find a non-profit organization that I like and believe in then I might feel more fulfilled working for them. I have a decent amount of web development experience and currently work as a Java / Spring web developer. I realize the compensation wouldn't have the same "ceiling" potential as for-profit but am wondering if its possible to get at least something close to a market rate for work as I am planning to start a family sometime soon and still need a legitimate income. If anyone has any knowledge or experience about this sort of thing would be happy to hear from you. EDIT: Without getting in to too much personal detail, I have a relative who recently passed away who suffered from a mental illness so while it doesn't have to be an organization specifically dedicated to this, I am hoping to work for something along these lines at least where there is more of a social cause rather than just working on an open-source project whose only cause is the advancement of technology.

  • Tip: Recording Non-Maximized Applications in UPK

    - by Marc Santosusso
    Have you ever wanted to record an application that would not maximize, or an application that would look strange maximized? Or perhaps your Windows Desktop has become cluttered with icons and you don't want to capture the clutter in your recordings. Here's a tip that will help: create a background for your recording. Create a blank HTML file with a black background in your favorite HTML editor. Or download this sample file: UPK_Recording_Background.html (right click to save). If you would prefer a different color background in the sample file, open it in Notepad and change “#000” to a different HTML color. Open UPK_Recording_Background.html in its own web browser window. Press F11 to make the web browser window full screen. This should give you a completely black screen. (This works great in modern versions of the most popular browsers. I successfully used Firefox 15, Chrome 22, and IE 9. Open or switch to the desired application so that it sits on top of the full screen browser window. If the application you are recording is also in a browser, it is important that it be in a separate browser window from the UPK_Recording_Background.html. Record your topic normally. The above steps create a recording background using an HTML file and a web browser. This is just one method, for instance you could do the same thing with an image editor and an image viewer with a full screen view. Now you can record a non-maximized application without a distracting background. I hope you find this to be a helpful tip. Let us know what you think in the comments.

  • How to highlight non-rectangular hotspots?

    - by HuseyinUslu
    So my question is highly related to Creating non-rectangular hotspots and detecting clicks. Yet again, I've irregular hot-spots (think the game Risk). So basically, we can detect clicks on these hot-spots easily using color key mapping as discussed in above question which I don't have any problems implementing (which is also covered here in details). The problem is about highlighting these irreguar hotspots. So let me explain the question a bit more - the above color key mapping guide uses this as a world map: Then the author color-maps the imaginary countries: Now we can now detect the country the pointer is over. In the same article author mentions outlining countries on mouse-over. Though to get the effect, he creates unique border assets for each country - like: For the game I'm working on I'm using the same color-key mapping idea to detect hot-spots, but I didn't like the way of highlighting hot-spots. Coloring all the hot-spots is already a time-consuming job for me - as I have 25+ hot-spots for each map. Further, the need to have 25 unique border/highlight asset per hot-spot doesn't sound right. Anyone have a better idea/suggestion on highlighting these hot-spots?

  • Dual Boot Installing Ubuntu 12.04 with Windows 7 (64) on a non UEFI system

    - by Randnum
    I cannot seem to install the correct boot loader for a non-UEFI firmware system. I'm trying to install Ubuntu 12.04 and Windows 7 (64) which are technically compatible with GPT but for windows only if the firmware is UEFI enabled. My system uses the old BIOS system and does not support UEFI. Therefore, whenever I finish my Ubuntu install and try to install Windows I get a "cannot install to GPT partition type" error. Even if I use Gparted to format a special NTFS file format for windows it can't handle the GPT partition style because it doesn't have UEFI. But my ubuntu install always forces GPT during installation and never asks if I want to install the old BIOS style MBR instead. How do I resolve this? Both OS's will install fine on their own the problem is when I try to install the second OS it doesn't recognize any of the other's partitions and tries to rewrite it's own on top of the other. I've tried both OS's first and always run into the same problem. Since there is no way to make Windows recognize GPT without upgrading my Motherboard how do I tell Ubuntu to use the old BIOS MBR on install? Do I have to download a special Ubuntu with a specific grub version? or should I manaually configure my partition somehow to force it not to use GPT? Thank you,

  • Count function on tree structure (non-binary)

    - by Spevy
    I am implementing a tree Data structure in c# based (largely on Dan Vanderboom's Generic implementation). I am now considering approach on handling a Count property which Dan does not implement. The obvious and easy way would be to use a recursive call which Traverses the tree happily adding up nodes (or iteratively traversing the tree with a Queue and counting nodes if you prefer). It just seems expensive. (I also may want to lazy load some of my nodes down the road). I could maintain a count at the root node. All children would traverse up to and/or hold a reference to the root, and update a internally settable count property on changes. This would push the iteration problem to when ever I want to break off a branch or clear all children below a given node. Generally less expensive, and puts the heavy lifting what I think will be less frequently called functions. Seems a little brute force, and that usually means exception cases I haven't thought of yet, or bugs if you prefer. Does anyone have an example of an implementation which keeps a count for an Unbalanced and/or non-binary tree structure rather than counting on the fly? Don't worry about the lazy load, or language. I am sure I can adjust the example to fit my specific needs. EDIT: I am curious about an example, rather than instructions or discussion. I know this is not technically difficult...

  • Effective handling of variables in non-object oriented programming

    - by srnka
    What is the best method to use and share variables between functions in non object-oriented program languages? Let's say that I use 10 parameters from DB, ID and 9 other values linked to it. I need to work with all 10 parameters in many functions. I can do it next ways: 1. call functions only with using ID and in every function get the other parameters from DB. Advantage: local variables are clear visible, there is only one input parameter to function Disadvantage: it's slow and there are the same rows for getting parameters in every function, which makes function longer and not so clear 2. call functions with all 10 parameters Advantage: working with local variables, clear function code Disadvantage: many input parameters, what is not nice 3. getting parameters as global variables once and using them everywhere Advantage - clearer code, shorter functions, faster processing Disadvantage - global variables - loosing control of them, possibility of unwanted overwriting (Especially when some functions should change their values) Maybe there is some another way how to implement this and make program cleaner and more effective. Can you say which way is the best for solving this issue?

  • touch detection of non-rectangular sprites (cocos2d)

    - by hogni89
    What is the correct way to implement a non-rectangular sprite in Cocos2d? I am working on a jigsaw puzzle. And therefor do our sprites have some strange forms (Jigsaw puzzle bricks). As of now, we have implemented the "detect" this way: - (void)selectSpriteForTouch:(CGPoint)touchLocation { CCSprite * newSprite = nil; // Loop array of sprites for (CCSprite *sprite in movableSprites) { // Check if sprite is hit. // TODO: Swap if with something better. if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) { newSprite = sprite; break; } } if (newSprite != selSprite) { // Move along, nothing to see here // Not the problem } } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; [self selectSpriteForTouch:touchLocation]; return TRUE; } I know that the problem is in the keyword "sprite.boundingBox". Is there a better way of implementing this, OR is it a limit when using sprites based on .png's? If so, how should I proceed? I'm new to iPhone and game development :D

  • Lost all non-linux hard drives

    - by Rick
    I've somehow lost access to all my non-linux drives. I'm not sure how. I have two other hard drives set up (a windows boot and an external usb I was using under windowsxp). A few days ago I could access both under linux with no problem. Now, I see them listed under media, but when I click on them, nothing is there (same thing happens when I go there in a term window). Now, the computer (under linux) sees them, but I can't see anything in them. (in nautilus it shows "(Empty)") Any ideas what happened or how to get access to them again? My guesses as to what might have caused it: -I was trying to set up AdobeAIR (unsuccessfully) and had to make and remove a couple of symbolic links. Never got that to work but maybe links I made or removed did something? -I was also trying to set up nautilus so that I could enter it with sudo permission. I also didn't figure out how to do that successfully, but maybe something I did while trying messed it up? (I think I installed and uninstalled nautilus-actions configuration tool). Note: I'm working on a relatively new install of 12.04
