• OpenSource license with commerial-use exemptions for the owner

  - by dbkk

  I'm looking for an open source license which grants me additional privileges. Features: Anyone can freely modify, fork, use the code, as long as they make their source changes publicly available. They can use it in other open source projects, but not in closed-source projects. Only I and entities I specifically designate can use the code as part of a closed-source application. I am also exempt from the duty to publish the source code changes. I'm not trying to forbid the commercial use, just to allow myself more flexibility to use the code, while still contributing to open source. I don't want to burn myself by being legally forbidden from using the libraries I wrote in my commercial projects. Large companies use such dual licenses to maintain an open source project, while also selling the premium version. Which licenses of this type are available? What caveats or obstacles exist?

• Alternative to "inheritance v composition??"

  - by Frank

  I have colleagues at work who claim that "Inheritance is an anti-pattern" and want to use composition systematically instead, except in (rare, according to them) cases where inheritance is really the best way to go. I want to suggest an alternative where we continue using inheritance, but it is strictly forbidden (enforced by code reviews) to use anything but public members of base classes in derived classes. For a case where we don't need to swap components of a class at runtime (static inheritance), would that be equivalent enough to composition? Or am I forgetting some other important aspect of composition?

• Apache2 and FTP

  - by Jo Colina

  I just set up an Apache web server on my Raspberry Pi, along with MySQL and PHP5, and to upload files i set up vsftpd. The thing is that the ftp connection sent me to my pi user home directory, instead of /var/www . So i changed Pi home directory to /var/www and changed it again to it's previous home. FTP now sends me to /var/www but whenever I upload files other rights are null. (Apache sends a 403 Forbidden every time unless I manually chmod the files inside /var/www uploaded via ftp) Does anyuone know how to fix this? Thanks!

• Does distributing non-GPLd assets with a GPL application violate the license?

  - by Richard Szalay

  This is somewhat related to my other question, but is actually different. I would like to license a Windows Phone application under the GPL. All other Windows Phone Marketplace issues aside (I'll ask those on the forums), I'd like to include icons that ship with the SDK in my application. While this is common practice (documentation points to the icons' location), I'm not sure if I'd be forcing GPL on the icons (a move expressly forbidden by the Application Provider Agreement). How is this usually handled in GPL or am I simply out of luck?

• Animations not accepted in animator

  - by Lautaro

  In the official Unity Animator State Machine tutorial video animation clips are dragged out from the assets folder into the animator and dropped. I have a 3D model that i bought online to experiment with that comes with animations. I added a custom made animation as well. These all work well in my demo project. But when i add a animator to the assets and try to drag and drop animations onto it it doesnt work. I get a forbidden-sign as a mouse pointer. I try to add animations through the inspector but that does not work either. The tutorials makes it seem so easy and does not talk anything about what animations can be used. What am i doing wrong?

  - by nishan

  Im running Ubuntu 12.04 LTS on a system with 2 GB RAM and a 500 GB HDD. My hard drive has 4 partitions: Partition 1 = 40 gb Windows (NTFS, lable = win32) Partition 2 = 320 gb Windows (FAT label = common) Partition 3 = 40 gb Ubuntu (EXT4) I installed apached2.

• How to patch libgphoto2 for preview pictures in Shotwell while importing?

  - by Erraticus

  Under some circumstances, Shotwell shows no photo thumbnails while importing. I was trying to download some pictures from my camera (Canon EOS 400D) with Shotwell and the program didn't show any preview for the pictures before downloading them (it just shows a "forbidden" snapshot). After importing them everything seems fine. I've found this bug report but no solution is given for now. It seems there could be a solution for EOS cameras, according to the last comment. This guy links to a patch, but it's not downloadable. Any ideas of where to obtain a deb package of this patch or of any other solution?

• Layering Design Pattern in Java clean code style

  - by zeraDev

  As a Java developer, I am developing trying to use the clean code rules. But in my team we are facing a concrete problem: We have a business layer offering a service called "createObject", this service makes a lot of operation which can result to problem. E.g: parentObjectDontExist, objectAlreadyExist, dontHaveAuthorizationToCreate, operationFailed... and we want the UI using this service to display different information messages depending which error occurred. In old java dev, we should have create all signed exception type and throw it in createObject. As Clean code says, it is forbidden to use Exception for business logic AND signed exceptions are evil... Why not...But i don't know how to solved this problem and i don't want to use return code. How do you do? Thanks for youre experience return.

• Call a function in an ExtJS XTemplate

  - by Snowright

  I'm familiar with using a function to determine a specific condition using xtemplate but not sure how to directly call a function without the conditional if statement. My code, for example, wants to append some characters to a string that I am using within my xtemplate. I think the best way to do it is append the characters when the xtemplate is rendered. var myTpl = new Ext.XTemplate( '<tpl for=".">', '<tpl if="this.isThumbnailed(thumbnailed) == true">', '<img src=this.getThumbUrl(rawThumbUrl)/>', //this call to function does not work, also tried variations of this. '</tpl>', '</tpl>', { isThumbnailed : function(thumbnailed) { return ...; }, getThumbUrl : function(rawThumbUrl) { //... //this function does not get called. return ...; } } )

• jquery - check length of input field?

  - by KnockKnockWhosThere

  The code below is intended to enable the submit button once the user clicks in the textarea field. It works, but I'm trying to also make it so that it's only enabled if there's at least one character in the field. I tried wrapping it in: if($(this).val().length > 1) { } But, that didn't seem to work... Any ideas? $("#fbss").focus(function(){ $(this).select(); if($(this).val()=="Default text") { $(this).val(""); $("input[id=fbss-submit]").removeClass(); $("input[id=fbss-submit]").attr('disabled',false); $("input[id= fbss-submit]").attr('class','.enableSubmit'); if($('.charsRemaining')) { $('.charsRemaining').remove(); $("textarea[id=fbss]").maxlength({ maxCharacters: 190, status: true, statusClass: 'charsRemaining', statusText: 'characters left', notificationClass: 'notification', showAlert: false, alertText: 'You have exceeded the maximum amount of characters', slider: false }); } });

• Ndk-build: CreateProcess: make (e=87): The parameter is incorrect

  - by user1514958

  I get an error when build static lib with NDK on Windows platform: process_begin: CreateProcess( "PATH"\android-ndk-r8b\toolchains\arm-linux-androideabi-4.6\prebuilt\windows\bin\arm-linux-androideabi-ar.exe, "some other commands" ) failed. make (e=87): The parameter is incorrect. make: *** [obj/local/armeabi-v7a/staticlib.a] Error 87 make: *** Waiting for unfinished jobs.... All source files build successfully, and this error occur when compose object files. I don't get this error when build this project in Ubuntu, it occur only on Windows. I suppose I found the issue: second parameter of CreateProcess Win API function lpCommandLine has max length 32,768 characters. But in my case it is more than 32,768 characters. How I can solve this issue?

• String length difference between ruby 1.8 and 1.9

  - by Raghu

  I have a website thats running on ruby 1.8.7 . I have a validation on an incoming post that checks to make sure that we allow upto max of 12000 characters. The spaces are counted as characters and tab and carriage returns are stripped off before the post is subjected to the validation. Here is the post that is subjected to validation http://pastie.org/5047582 In ruby 1.9 the string length shows up as 11909 which is correct. But when I check the length on ruby 1.8.7 is turns out to be 12044. I used codepad.org to run this ruby code which gives me http://codepad.org/OxgSuKGZ ( which outputs the length as 12044 which is wrong) but when i run this same code in the console at codeacademy.org the string length is 11909. Can anybody explain me why this is happening ??? Thanks

• ASP.NET MVC2 RC : How to intercept or trigger client-side validation before ajax request?

  - by jacko

  I have a username textbox on a form, that has a few validation rules applied to it via the DataAnnotation attributes: [Required(ErrorMessage = "FTP login is required")] [StringLength(15, ErrorMessage = "Must be 15 characters or fewer")] [RegularExpression(@"[a-zA-Z0-9]*", ErrorMessage = "Alpha-numeric characters only")] public string FtpLogin { get; set; } I also have a button next to this text box, that fires off a jQuery ajax request that checks for the existence of the username as follows: <button onclick="check(this);return false;" id="FtpLoginCheck" name="FtpLoginCheck">Available?</button> I'm looking for a way of tieing the two together, so that the client-side validation is performed before the call to the "check(this)" in the onclick event. Edit: To be more clear, I need a way to inspect or trigger the client-side validation result of the textbox, when I click the unrelated button beside it. Edit: I now have the button JS checking for $("form").validate().invalid, but not displaying the usual validation messages. Almost there Any ideas?

• How to set the mechanize page encoding?

  - by Juan Medín

  Hi, I'm trying to get a page with an ISO-8859-1 encoding clicking on a link, so the code is similar to this: page_result = page.link_with( :text => 'link_text' ).click So far I get the result with a wrong encoding, so I see characters like: 'T?tulo:' instead of 'Título:' I've tried several approaches, including: Stating the encoding in the first request using the agent like: @page_search = @agent.get( :url => 'http://www.server.com', :headers => { 'Accept-Charset' => 'ISO-8859-1' } ) Stating the encoding for the page itself page_result.encoding = 'ISO-8859-1' But I must be doing something wrong: a simple puts always show the wrong characters. Do you know how to state the encoding? Thanks in advance, Added: Executable example: require 'rubygems' require 'mechanize' WWW::Mechanize::Util::CODE_DIC[:SJIS] = "ISO-8859-1" @agent = WWW::Mechanize.new @page = @agent.get( :url => 'http://www.mcu.es/webISBN/tituloSimpleFilter.do?cache=init&layout=busquedaisbn&language=es', :headers => { 'Accept-Charset' => 'utf-8' } ) puts @page.body

• What is the best way to remove accents in a python unicode string?

  - by MiniQuark

  I have a unicode string in python, and I would like to remove all the accents (diacritics). I found on the Web an elegant way to do this in Java: convert the unicode string to its long normalized form (with a separate character for letters and diacritics) remove all the characters whose unicode type is "diacritic". Do I need to install a library such as pyICU or is this possible with just the python standard library? And what about in python 3.0? Important note: I would like to avoid code with an explicit mapping from accented characters to their non-accented counterpart. Thanks for your help.

• Check ReturnUrl is valid before redirecting

  - by Josh

  I'm using ASP.NET Membership and Form Authentication and before redirecting to the returnURL I wanted to validate it. For those unfamiliar with the workflow, basically if you request a page that requires that you are authenticated, you are redirected to a login page. In the URL string you'll see a parameter called returnURL, e.g. http://example.com/login.aspx?ReturnUrl=%2fprotected%2fdefault.aspx Whether you use this in a redirect such as Response.Redirect(returnURL) or indirectly through the FormsAuthentication.RedirectFromLoginPage method, it passes without validating returnURL. FormsAuthentication.RedirectFromLoginPage does have a security check that it is isn't leaving the domain, but that still doesn't stop someone from putting enough random characters to cause an error. I tried using System.IO.File.Exists(Server.MapPath(returnURL)) but given enough illegal characters it cause Server.MapPath to error. Note: URLEncoding doesn't work because we are not cleaning a parameter, but the primary URL. Any other suggestions for validating or cleaning the returnURL value?

• How can I tell if a CSV is in UTF-7 or UTF-8

  - by dru-zod

  Excel seems to save CSV files in (what I think is) UTF-7, despite the fact that most information I have read suggest that in general, you should not UTF-7. Indeed, other applications (Text pad, which lets me choose) save things in UTF-8 (or Unicode etc, but UTF-7 is not even an option). Using .NET, I read the stream, and have to provide the encoding. If I get it wrong, accented characters are replaced with question marks. If I try and let StreamReader work it out (using detectEncodingFromByteOrderMarks), it gets it wrong (at least, it does if the file has been saved in Excel). It is unlikely that anything other then Excel will be used, so I could just assume UTF-7. Are there any other options? I need to support French (accented), German, Dutch, and Norwegian characters.

• Can you access registers from python functions in vim

  - by Michael Anderson

  It seems vims python sripting is designed to edit buffer and files rather than work nicely with vims registers. You can use some of the vim packages commands to get access to the registers but its not pretty. My solution for creating a vim function using python that uses a register is something like this. function printUnnamedRegister() python >> EOF print vim.eval('@@') EOF Setting registers may also be possible using something like function setUnnamedRegsiter() python >> EOF s = "Some \"crazy\" string\nwith interesting characters" vim.command('let @@="%s"' % myescapefn(s) ) EOF However this feels a bit cumbersome and I'm not sure exactly what myescapefn should be. So I've never been able to get the setting version to work properly. So if there's a way to do something more like function printUnnamedRegister() python >> EOF print vim.getRegister('@') EOF function setUnnamedRegsiter() python >> EOF s = "Some \"crazy\" string\nwith interesting characters" vim.setRegister('@',s) EOF Or even a nice version of myescapefn I could use then that would be very handy.

• Programmatically change the default code page in Windows XP? (from Delphi)

  - by Duncan

  Could anyone advise how to programmatically change the default Windows XP code page (I'm doing this from Delphi)? (This would be the equivalent of going into Control Panel - Regional Settings - Language for non-Unicode applications). In this case, I want to switch to Chinese (PRC) and so am writing to the following registry strings: HKLM\SYSTEM\CurrentControlSet\Control\Nls\CodePage\ ACP=936 MACCP=10008 OEMCP=936 (Which is exactly what changing the non-Unicode codepage drop down in Control Panel does). There must be another setting which I need to change - and I'd prefer to use a Win API call (if available) rather than writing to the registry myself. I've also tried setting HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language\ Default=0804 (Chinese PRC) to no avail. I don't want to change the 'locale' per se as this will also change time / date settings, separators, etc. etc. This is because I'm using an ANSI application that needs to render Chinese characters, and I'm writing a tool to automatically switch the system show the characters (while leaving other aspects of the UI intact). Thanks! Duncan

• Split textarea content into two at maxlength and flow excedant content in another textarea

  - by user1057339

  Wondering if its possible to create a short simple and sweet cross-browser jQuery (1.6) function that would split #textarea1 content into two by preserving the characters that amount to less than its var maxlength limit and transfering the remaining characters that exceed its maxlength limit in #textarea2. #textarea1 can push excedant in #textarea2, but if #textarea1 contains less than the maxlength limit, by default it wont get filled up with #textarea2 content, but you would have the option programatically to override this. I am just beginning to scratch the surface of jQuery but I noticed that this simple javascript can nearly do the trick, minus the free-flowing character movement. Scratching my head on this one. Thx a heap for any help. DC

• javascript - shorten string to fit into a certain # of lines

  - by Mala

  Hi I have a string that must fit into a box, and must be at most 3 lines long. To shorten it, I plan to truncate it and end it with '...'. I could shorten it to a certain # of characters but if i make it look good with "wwwwwwwww [...] wwww" it won't look right with "iiiiiiiiiii [...] iiii". Is there some way I can shorten it by how much space the string would take up, as opposed to how many characters there are in a string without using a fixed-width font? Mala ps. Please no "simply create an image of '...' and overlay it over the end of the line" hacks or similar - I actually want to shorten the string to the appropriate length
