• Is my form password being passed in clear text?

  - by liinkas

  This is what my browser sent, when logging into some site: POST http://www.some.site/login.php HTTP/1.0 User-Agent: Opera/8.26 (X2000; Linux i686; Z; en) Host: www.some.site Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png, image/jpeg, image/gif, image/x-xbitmap, */*;q=0.1 Accept-Language: en-US,en;q=0.9 Accept-Charset: iso-8859-1, utf-8, utf-16, *;q=0.1 Accept-Encoding: deflate, gzip, x-gzip, identity, *;q=0 Referer: http://www.some.site/ Proxy-Connection: close Content-Length: 123 Content-Type: application/x-www-form-urlencoded lots_of_stuff=here&e2ad811=my_login_name&e327696=my_password&lots_of_stuff=here Can I state that anyone can sniff my login name and password for that site? Maybe just on my LAN? If so (even only on LAN ) then I'm shocked. I thought using <input type="password"> did something more than make all characters look like ' * ' p.s. If it matters I played with netcat (on linux) and made connection browser <= netcat (loged here) <= proxy <= remote_site

• Added tagging to existing model, now how does its admin work?

  - by Oli

  I wanted to add a StackOverflow-style tag input to a blog model of mine. This is a model that has a lot of data already in it. class BlogPost(models.Model): # my blog fields try: tagging.register(BlogPost) except tagging.AlreadyRegistered: pass I thought that was all I needed so I went through my old database of blog posts (this is a newly ported blog) and copied the tags in. It worked and I could display tags and filter by tag. However, I just wrote a new BlogPost and realise there's no tag field there. Reading the documentation (coincidentally, dry enough to be used as an antiperspirant), I found the TagField. Thinking this would just be a manager-style layer over the existing tagging register, I added it. It complained about there not being a Tag column. I'd rather not denormalise on tags just to satisfy create an interface for inputting them. Is there a TagManager class that I can just set on the model? tags = TagManager() # or somesuch

• Do i *have* to use ObservableCollection in Silverlight WCF client?

  - by Simon_Weaver

  When accessing Silverlight in WCF you get proxies generated with ObservableCollection Thats fine when you're databinding, but a little clumsy when you're just calling a method. For instance the following service method : [OperationContract] public SearchOrdersMsgOut SearchOrders(ShippingStatusType[] shippingStatuses, string[] orderId) { } gets generated with ObservableCollection. What! They're just parameters. Why would I ever want to 'observe' them? I'm fine if I have to do this - but it seems like there should be a way to force simple array structures when I know I'm never databinding - especially on input messages. I'd much rather do this : searchCriteria.PaymentStatus = new [] { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; than this : searchCriteria.PaymentStatus = new ObservableCollection<PaymentStatusType> { PaymentStatusType.PaymentFailed, PaymentStatusType.Unpaid }; Is there a way? PS. I do actually use a SearchCriteria object for my search criteria - but I simplified for this example wondering if parameters were handled differently.

• JSON Date coming through as Today's date?

  - by Liam

  I'm trying to convert a JSON date to a dd/mm/yyyy format, which I'm managing to do semi-successfully. The problem I'm encountering is that the date from the record in the DB is for example, 2009-06-29 which is returning the usual JSON /Date(1246230000000)/, however, when I try and turn it into the previously mention dd/mm/yyyy format, it's coming through as today's date. The code I'm using to try and do this is: $('input#EmployeeName').result(function(event, data, formatted) { $('#StartDate').html(formatJSONDate(Date(!data ? '' : data.StartDate))); }); function formatJSONDate(jsonDate) { var newDate = dateFormat(jsonDate, "dd/mm/yyyy"); return newDate; } I'm using JavaScript Date Format to try and run the function. Any help is greatly appreciated.

• Intra-Unicode "lean" Encoding Converters

  - by Mystagogue

  Windows provides encoding conversion functions ("MultiByteToWideChar" and "WideCharToMultiByte") which are capable of UTF-8 to/from UTF-16 conversions, among other things. But I've seen people offer home-grown 30 to 40 line functions that claim also to perform UTF-8 / UTF-16 encoding conversions. My question is, how reliable are such tiny converters? Can such a tiny amount of code handle problems such as converting a UTF-16 surrogate pair (such as ) into a UTF-8 single four byte sequence (rather than making the mistake of converting into a pair of three byte sequences)? Can they correctly spot "unpaired" surrogate input, and provide an error? In short, are such tiny converters mere toys, or can they be taken seriously? For that matter, why does unicode.org seemingly offer no advice on an algorithm for accomplishing such conversions?

• Simple but efficient way to store a series of small changes to an image?

  - by finnw

  I have a series of images. Each one is typically (but not always) similar to the previous one, with 3 or 4 small rectangular regions updated. I need to record these changes using a minimum of disk space. The source images are not compressed, but I would like the deltas to be compressed. I need to be able to recreate the images exactly as input (so a lossy video codec is not appropriate.) I am thinking of something along the lines of: Composite the new image with a negative of the old image Save the composited image in any common format that can compress using RLE (probably PNG.) Recreate the second image by compositing the previous image with the delta. Although the images have an alpha channel, I can ignore it for the purposes of this function. Is there an easy-to-implement algorithm or free Java library with this capability?

• translate by replacing words inside existing text

  - by Berry Tsakala

  What are common approaches for translating certain words (or expressions) inside a given text, when the text must be reconstructed (with punctuations and everythin.) ? The translation comes from a lookup table, and covers words, collocations, and emoticons like L33t, CUL8R, :-), etc. Simple string search-and-replace is not enough since it can replace part of longer words (cat dog ? caterpillar dogerpillar). Assume the following input: s = "dogbert, started a dilbert dilbertion proces cat-bert :-)" after translation, i should receive something like: result = "anna, started a george dilbertion process cat-bert smiley" I can't simply tokenize, since i loose punctuations and word positions. Regular expressions, works for normal words, but don't catch special expressions like the smiley :-) but it does . re.sub(r'\bword\b','translation',s) ==> translation re.sub(r'\b:-\)\b','smiley',s) ==> :-) for now i'm using the above mentioned regex, and simple replace for the non-alphanumeric words, but it's far from being bulletproof. (p.s. i'm using python)

• How can it be impossible to "decrypt" an MD5 hash?

  - by Rob

  I was reading a question about MD5, and it made me remember something that boggles me. Very simple question, and I'm sorry if it's not a good one. I just can't understand how you convert something to one thing using some algorithm, and there being no way to convert it back using the algorithm in reverse. So how is this possible? Also, since multiple strings can create the same MD5 hash, due to it being less data than the input string, how would any other hashing system be any better?

• where should we place HIDDEN variable in JSP

  - by micheal

  I need to use Hidden variables in my JSP for session tracking. this is the code: <input type="hidden" name="REQ_TOKEN" value="<%=session.getAttribute("SESN_TOKEN").toString()%>" /> i am using this to compare the request token with session token, so only when both are equal i will evaluate that request otherwise i will throw an error. Now the problem is, when i place this code inside <form></form> tags, it is working fine. Unfortunately there are some JSPs in my application where we dont have tag(I know that sounds weird!). where can i place my code so that it will work? Cant i use Hidden variables without FORM tag???

• Very long strings as primary keys in a database for caching

  - by Bill Zimmerman

  Hi, I am working on a web app that allows users to create dynamic PDF files based on what they enter into a form (it is not very structured data). The idea is that User 1 enters several words (arbitrary # of words, practically capped of course), for example: A B C D E There is no such string in the database, so I was thinking: Store this string as a primary key in a MySQL database (it could be maybe around 50-100k of text, but usually probably less than 200 words) Generate the PDF file, and create a link to it in the database When the next user requests A B C D E, then I can just serve the file instead of recreating it each time. (simple cache) The PDF is cpu intensive to generate, so I am trying to cache as much as I can... My questions are: Does anyone have any alternative ideas to my approach What will the database performance be like? Is there a better way to design the schema than using the input string as the primary key?

• How do I add a textbox to my other jQuery click function?

  - by marcamillion

  Right now, my script adds a box to the cursor when I click on an image, as can be seen in the following code. Please note, this is jQuery. $(function() { var tag_box = $("<div>").appendTo("body").css({"width":"40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px"}); $("#image-wrapper").live('click', function(e){ tag_box.css({"left": e.pageX - 40, "top": e.pageY - 40, "display":"block"}); }); I would like to add a text field to appear right below that tag_box on that same click. I tried to do this, but it hasn't worked out like I thought it would: var comment_box = $("<label> Comment: <input type='text' name='comment' autocomplete='off'></label>"); $("#image-wrapper").live('click', function(){ $("body").append(comment_box); }); Any assistance you can give me, would be greatly appreciated. Thanks.

• pyparsing ambiguity

  - by Claudiu

  I'm trying to parse some text using PyParser. The problem is that I have names that can contain white spaces. So my input might look like this: Joe Bob Jimmy Foo Joe decides to eat. Bob decides to not eat. Jimmy Foo decides to eat. How can I create a parser for the decides to eat line? If I create my name parser naively, meaning with alphabetic characters plus space characters, then it will match the entire line.

• Self documenting REST interface

  - by KandadaBoggu

  I have a Rails based server running several REST services and a Rails based web UI that interacts with the server using ActiveResource. Same server is being used by other clients( e.g: mobile). I have to generate documentation for the REST interface. I need to provide service URL, input/output and error document structure for each service. Ideally, I would like to use an interceptor at the server side that will document the service based on the existing traffic. I am wondering if there is a gem to do this.

• Respect regular onsubmit handlers from jQuery.submit

  - by orip

  I want a jQuery form submit handler to respect any previous submit handlers, including ones added with onsubmit. I'm trying to detect the previous handler's return value but can't seem to do it: <form><input type="submit" /></form> <script type="text/javascript"> $('form')[0].onsubmit = function() { return false; }; // called first $('form').submit(function(e) { console.log(e.result); // undefined console.log(e.isDefaultPrevented()); // false console.log(e.isPropagationStopped()); // false console.log(e.isImmediatePropagationStopped()); // false }); </script> Is there a way to do this?

• Difference between piping a file to sh and calling a shell file

  - by Peter Coulton

  This is what was trying to do: $ wget -qO- www.example.com/script.sh | sh which quietly downloads the script and prints it to stdout which is then piped to sh. This unfortunately doesn't quite work, failing to wait for user input a various points, aswell as a few syntax errors. This is what actually works: $ wget -qOscript www.example.com/script.sh && chmod +x ./script && ./script But what's the difference? I'm thinking maybe piping the file doesn't execute the file, but rather executes each line individually, but I'm new to this kind of thing so I don't know.

• [iPhone] presentModalViewController not working

  - by ryyst

  Hi, here's my code: ViewController *vc = [[ViewController alloc] initWithNibName:@"TableView" bundle:nil]; [self.navigationController presentModalViewController:vc animated:YES]; //[self setView:[vc view]]; If I call it, nothing happens. However, if I change it to: ViewController *vc = [[ViewController alloc] initWithNibName:@"TableView" bundle:nil]; //[self.navigationController presentModalViewController:vc animated:YES]; [self setView:[vc view]]; The view appears just fine (without the transition, of course). What am I doing wrong? Is there anything special you have to take care of when initializing the view controller? I tried to copy as much as possible from Apple's examples, but I can't get this to work... Thanks for any input! -- Ry

• How to preserve hyperlink when submitting via php form into MySQL

  - by TheTub

  Hi All, I've created a form that stores free text fields into a MySQL database. All works fine and the data is displayed back as intended when viewed. Except for one niggle. In an attempt to prevent malicious attacks I have used mysql_real_escape_string to remove any unwanted code from the input. However, I need to be able to preserve hyperlinks and basic html. For example, I want to store the following: <p align="left">Please follow this <a href="link.html">link</a></p> But the link is being stored as \"link.html\" as the quotes are being escaped. How can I preserve this link and other html? Many thank TT

• Data-related security Implementation

  - by devdude

  Using Shiro we have a great security framework embedded in our enterprise application running on GF. You define users, roles, permissions and we can control at any fine-grain level if a user can access the application, a certain page or even click a specific button. Is there a recipe or pattern, that allows on top of that, to restrict a user from seeing certain data ? Sample: You have a customer table for 3 factories (part of one company). An admin user can see all customer records, but the user at the local factory must not see any customer data of other factories (for whatever reason). Te security feature should be part of the role definition. Thanks for any input and ideas

• Only some windows shell commands work via ruby?

  - by Sanarothe

  Hi. I'm trying to use a script to control my power options since XP doesn't give you an intuitive way to change CPU Frequency options. Here's my script so far: meh = `cmd.exe /C POWERCFG.EXE /QUERY Portable/Laptop` puts "" puts meh case input when 1 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac NONE') when 2 then system('cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac ADAPTIVE') when 3 then `cmd.exe /C POWERCFG.EXE /CHANGE Portable/Laptop /processor-throttle-ac CONSTANT` end The problem is that the changes simply don't take place. If I run the same commands directly into a cmd.exe prompt, they work. It's very strange, but nothing works after the initial powercfg query. I feel like I'm missing something incredibly obvious. How can I get the above script to run correctly?

• Rails i18n and routes in javascript

  - by StefanS

  Sometimes it would be really handy to have the Rails localization files available in JavaScript. Same is true for for the routes helpers. I found these two plugins which are exactly doing this: Exposing i18n to JavaScript: http://github.com/fnando/i18n-js Rails Routes in JavaScript: http://tore.darell.no/pages/javascript_routes My questions: Are there any other plugins / gems doing similar things like the two above? What's the right approach in Rails? Meta tag? Additional data- attributes? Thanks for any input!

• What are some good design patterns for CRUD?

  - by Extrakun

  I am working with a number of data entities which can be created, read, updated and deleted, and I find myself writing more or less the same code for them. For example, I need to sometimes output data as JSON, and sometimes in a table format. I am finding myself writing 2 different types of view to export the data to. Also, the creation of those entities within DB usually differs just by the SQL statements and the input parameters. I am thinking of creating a strategy pattern to represent different 'contexts'. For example, the read() method of an AJAX context will be to return the data as JSON. However, I wonder if others have deal with this problem beforehand and will like to know what design patterns are usually use for CRUD operations.

• CreateChildControls AFTER Postback

  - by Francois

  I'm creating my own CompositeControl: a collection of MyLineWebControl and a "add" button. When the user press the "add" button, a new MyLineWebControl is added. In CreateChildControls(), I run through my model (some object MyGridOfLines which has a collection of MyLine) and add one MyLineWebControl for each MyLine. In addButton.Click, I add a new MyLine to my object MyGridOfLines. But, since the Click event method is called after CreateChildControls(), the new MyLineWebControl will be only displayed on the next postback. What can I do to "redraw" immediately my control, without loosing values that I've entered in each input?

• Write wave files to memory in Java

  - by Cliff

  I'm trying to figure out why my servlet code creates wave files with improper headers. I use: AudioSystem.write( new AudioInputStream( new ByteArrayInputStream(memoryBytes), new AudioFormat(22000, 16, 1, true,false), memoryBytes.length ), AudioFileFormat.Type.WAVE, servletOutputStream ); taking a byte array from memory containing raw PCM samples and a servlet output stream that gets returned to the client. In the result I get a normal wave file but with zeros in the chunk size fields. Is the API broken? I would think that the size could be filled in using the size passed in the audio input stream. But now, after typing this out I'm thinking its not making this info available to the outer write() method on AudioSystem. It seems like the AudioSystem.write call needs a size parameter unless it is able to pull the size from the stream... which wouldn't work with an arbitrary sized stream. Does anyone know how to make this example work?
