• DOM and Javascript

  - by Bob Smith

  I let a user reconfigure the location of a set of rows in a table by giving them ability to move them up and down. The changes are done by swapping nodes in the DOM. After the user has moved rows around, when I do a view source, I see the HTML in the original state (before the user made any changes). Can someone explain why that is? My understanding was when we do any DOM operations, the underlying HTML will be changed as well. EDIT: Does that mean on the server side, when attempt to get the state after user's changes, I will be able to get what I need? I am using C#/ASP.NET. Could it be because this is a HTML table (not ASP.NET Server control), that it's not maintaining the state of the changes?

• Mercurial clone operation works, but I don't have write access

  - by normalocity

  Somewhere I did something silly. I was deploying my Rails app via cloning the Mercurial repo down onto my Ubuntu server. It worked the first time, and then...well, I made a small change on my dev machine, pushed the changes to the repo, and then deleted the copy on the Ubuntu server and re-cloned from the repo. The clone operation (the second, and third, and 'n' times) works without error, but I don't have write access to the files that were cloned. When I try to startup my mongrel - it can't create the /tmp folder, and because of no write access, fails to start the Rails app.

• Finding out if an IP address is static or dynamic?

  - by Joshua

  I run a large bulletin board and I get spammers every now and again. My moderation team does a good job filtering them out but every time I IP ban them they seem to come back (I'm pretty sure it's the same person on some occasions, as the post patterns are exactly the same as are the usernames) but I'm afraid to ban them by IP address every time. If they are on a dynamic IP address, I could be banning innocent users later down the line when they try to get to my forum through SERPs, but if I ban only via static IPs I know that I'm only banning that one person. So, is there a way to properly determine if an IP address is static or dynamic? Thanks.

• Software Requirement Specifications for Web Applications

  - by illuminatedtiger

  Hi guys, I'm looking for some guidance/books to read when it comes to creating a software requirement specification for a web application. For inspiration I have read some spec documents for desktop based applications. The documents I have read capture a systems functional requirements in use cases which tend to be rather data oriented with use cases centered around the various CRUD operations the application is intended to perform. I like this structure however I'm finding it rather difficult to marry it to what my web application needs to do, mostly reading data as opposed to manipulating it. I've had a go at writing some use cases however they all tend to boil down to "Search for item", "Change view of search results" or "User selects facet to refine search results". This doesn't sound quite right to me and makes me wonder if I'm going about this the right way. Are there planning differences between web based and desktop based applications?

• php regex to remove HTML

  - by Me1000

  Before we start, strip_tags() doesn't work. now, I've got some data that needs to be parsed, the problem is, I need to get rid of all the HTML that has been formated very strangely. the tags look like this: (notice the spaces) < p > blah blah blah < / p > < a href= " link.html " > blah blah blah < /a > All the regexs I've been trying aren't working, and I don't know enough about regex formating to make them work. I don't care about preserving anything inside of the tags, and would prefer to get rid of the text inside a link if I could. Anyone have any idea? (I really need to just sit down and learn regular expressions one day)

• Lexing partial SQL in C#

  - by Chris T

  I'd need to parse partial SQL queries (it's for a SQL injection auditing tool). For example '1' AND 1=1-- Should break down into tokens like [0] => [SQL_STRING, '1'] [1] => [SQL_AND] [2] => [SQL_INT, 1] [3] => [SQL_AND] [4] => [SQL_INT, 1] [5] => [SQL_COMMENT] [6] => [SQL_QUERY_END] Are their any at least lexers for SQL that I base mine off of or any good tools like bison for C# (though I'd rather not write my own grammar as I need to support most if not all the grammar of MySQL 5)

• jQuery Sortable + Droppable z-index problem

  - by unknowndomain

  I am having a probelm with the z-index of my sortable object not being above my droppable. If you visit http://clareshilland.unknowndomain.co.uk/. Press Ctrl + L to bring up the login screen. Enter the username clare and the password shilland. It will then load in the admin bar and if you click manage gallery. A pop down thumbnail view will appear with all the photos from that gallery. The issue is that when you drag the 'polaroids' from the grid to the delete area they are under the delete area. I tried putting the delete area inside the same div as the grid but it makes no difference, I just don't know what to do at this point so any help would be a massive help!

• Is it possible to host a website in the 'ether' of the Internet -- not on a server -- so that it can

  - by Christopher Altman

  This is a theoretical problem I am curious about. Websites are hosted on servers. Servers can be taken offline. Is it possible to host a website in the 'ether' of the Internet -- not on a server -- so that it cannot be taken down? One example, is that the website is hosted on other websites, like a parasite. Another is that it is assembled through storing pieces on DNS machines, routers, etc., so that it get assembled on the fly. The purpose is that this website could live forever because no one person can remove it. The answers I am looking for are plausible idea/approaches on technically how this could be built.

• In search of a packaged .Net security solution for web-forms.

  - by Chuck Conway

  We are looking for a security solution for asp.net that has security down to the control level. This is not a necessity but, it would be nice. At the very least it needs to extend-able to allow for control level permissions. The solution should have an administration panel of some sort. It also needs to support roles, groups, and individual permissions. We haven't seen anything like this in the marketplace -- we are in the process of rolling our own solution. We'd rather use an off the shelf solution.

• StackOverflow Site Layout Problem in Chrome

  - by Laramie

  I was cleaning up one of my questions here and noticed that Stack Overflow's comments were overflowing into the right column in Chrome. The question is, what's the difference in CSS handling between Chrome and Firefox. I don't have access to Safari, Opera, et al. Can someone tell me in which browsers the error manifests? Is it just me? Here's the layout error: (my apologies to Tim Down for covering up his name with my comment bubble) Since I have no natural skill for good layouts and the whole process makes me sad, I wonder if someone can diagnose the error on StackOverflow and make a recommendation on how to avoid it. Is this a consequence of embedding a div inside a td? Plus I admit it. It's fun to point out an error on one of the greatest sites ever.

• Clojure lots of threads

  - by Timothy Baldridge

  I just got done watching Rick Hickey's "Clojure Concurrency" talk, and I have a few questions about threads. Let's say I have a situation with lots of Agents, let's say 10,000 of them running one machine. I'd rather not have 10,000 CPU threads running at once, but I don't want threads to be blocked by the actions of other threads. In this example I won't really be waiting for replies, instead each Agent will be sending a message or two, and then waiting until it gets a message. How would I structure a program like this without getting 10k OS threads which would probably end up slowing the system down.

• Convert wife/husband/partner to a programmer.

  - by Stefan

  originally posted by Stefan: How many of you have had the thought of educate your partner and invite him/her to the beautiful world of programming? I once started to give my wife lessons twice a week, It was a competition between me and another programmer, we thought it would be nice to have our wives understand why we work as programmers and also have it as a hobby sitting all night long. Maybe we could get our wives to feel the power too? After a couple of months my wife didn't like the idea any more, it was too hard to understand she thought, same for my friends wife. So now we are thinking of some project that would be too fun for our wives to turn down just to get the spirit up again. It would be nice to hand over a project to my wife, "Can you debug this for me, please? There are some strange error on module xxx." :) Maybe I'm crazy, what do you think?

• Use anchor to display div

  - by scatteredbomb

  I'm using jquery, and need to accomplish a couple things. 1) When someone clicks on a link (or in my case, a div) to display another div, I'd like to add an anchor to the url. So, if someone clicks on a "Live" link, the 'live' div slides down, and we append #live to the url. 2) If someone visits that page and keeps the #live anchor at the end of the url, then the 'live' div should be visible right away. I know how to handle the basic part of slideDown() if someone clicks a div. I don't know how to append the hashtag, or make it so that when the page is loaded that hashtag is checked and displays the respective div. Any help understanding this would be appreciated. Thanks in advance.

• Html.DropDownListFor() in Mozilla Firefox

  - by Andrey

  I'm rendering a drop down list using Html.DropDownListFor() extension. The markup I get is as follows: select id="NationalityId" name="NationalityId" option value="" /option option selected="selected" value="1"Estonian /option option value="2"Russian /option option value="3"Ukranian /option option value="4"Belorussian /option option value="5"Swedish /option option value="6"Dutch /option /select As you can see, option with value==1 is selected. But in Firefox 3.6.3 it doesn't display as selected, empty string (first option - value == "") is displayed instead. IE7 and Chrome render the page right - the option is selected. Does anybody know what is going on? How do I get this around?

• Simple Android OpenGL App Lag

  - by Eugene

  Hi, I have an Android OpenGL application which simply draws 2D squares (using 2 triangles) and animates them moving down the screen. I essentially do this by running: glLoadIdentity(), then glTranslatef, and finally glDrawElements all in a for loop. (The for loop is to draw all 10 blocks on the screen for every frame). In every drawFrame, the y-position of the blocks increments for the animation. The problem I'm having is strange. I run the application and the animation is laggy and not smooth. Then I re-run the application and I get a smooth animation. If I run again, I may get a smooth animation, or possibly not. Is my method correct, or is there a better way of doing this animation? Thanks for the help!

• CSS border and the :hover dynamic pseudo-class

  - by dbasch

  Hi All, I have built a persistent dropline menu with two levels using only CSS. It is pretty standard. It is a nested set of UL's and the UL's :hover state is what shows and hides the sub menu levels. Something like this: | *Pets* | Colors | Cars | | Cats | Dogs | Birds| Goats | Sheep | | Pets | *Colors* | Cars | | Red | Orange | Green | Blue| Yellow | I then added a 1px border at the bottom of the first level UL element. Like this: | *Pets* | Colors | Cars | -------------------------------------- | Cats | Dogs | Birds| Goats | Sheep | When I hover over a first level item (Pets), and then move the mouse down to the second level (Cats), the entire second level disappears. I finally figured out that the UL's 1px border is not included in the hover area for the UL. Can I add a border to the bottom of a dropline menu level without messing up the menu hovering? Thanks!

• Capturing USB Plug/Unplug events in Firemonkey

  - by radsdau

  [RAD Studio XE3 / C++] I have a FMX project running in Windows only at this stage, but I need to detect events when USB devices are connected and disconnected. I have a similar VCL app that can do this fine, but the Application-HookMainWindow is not exposed in FMX (only VCL). Is there an elegant way to handle this? Or do I have to hack some VCL stuff into my FMX app to make that work? I'd imagine I have to abstract it so I can support other platforms down the track. For the meantime though I need to get the Windows solution working. If the 'VCL hack' thing is required, how would I reference the vcl::Forms::Application from within my Fmx app? Cheers.

• MySQL Export with Column Heading

  - by st4nt0n

  Hello - I am very, very, new to mySQL. I've got experience in general technical terms, but not with the syntax or concepts of mySQL. I have been tasked with exporting a table from MySQL into a pipe delimited .txt or .xls that I can use to add 7500 more records to manually, then import back into the table. I tried to use INTO OUTFILE, but I don't get column headings, which I need for reference to merge the new records. Is there a good resource that can explain this to a complete novice? I would usually go down to my bookstore and start learning, but I'm on a bit of a time crunch. Thanks all!

• C, Linux: Receiving data from multiple multicast address on same port - how to distinguish them?

  - by Gigi

  2 vote down star I have an application that is receiving data from multiple multicast sources on the same port. I am able to receive the data. However, I am trying to account for statistics of each group (i.e. msgs received, bytes received) and all the data is getting mixed up. Does anyone know how to solved this problem? If I try to look at the sender's address, it is not the multicast address, but rather the IP of the sending machine. I am using the following socket options: struct ip_mreq mreq; mreq.imr_multiaddr.s_addr = inet_addr("224.1.2.3"); mreq.imr_interface.s_addr = INADDR_ANY; setsockopt(s, IPPROTO_IP, IP_ADD_MEMBERSHIP, &mreq, sizeof(mreq)); and also: setsockopt(s, SOL_SOCKET, SO_REUSEPORT, &reuse, sizeof(reuse)); I appreciate any help!!!

• Find the xmlHttpRequest resource in aspx page

  - by DJStroky

  I'm trying to find an xmlHttpRequest or similar resource that I can query directly to obtain an xml file for my own purposes. At this site it is possible to browse a Google Map mashup with markers. Unfortunately it is only possible to view all markers at a small view range, whereas I simply want to obtain all the information at once for the entire state. Using the firebug console in firefox I can enter the following javascript line to obtain the xml that I desire: document.getElementById("stationXML").value I tracked this document element down to an <input> tag, but I can't figure out how that input is set. Thanks in advance for your help!

• How do I layout an image that will be dynamically sized in interface builder?

  - by Tony

  I am having trouble laying out scrollable view in interface builder. A screen shot of my layout is here. As you can see the layout is pretty simple. The UIImageView above the text will not have a specific height. It may be 100px high or 300px high. This is why the view is scrollable. I am experiencing two problems with this layout: 1) For some reason the image will sit behind the text instead of pushing it down. Take a look here. 2) The obvious other problem is that the upper most UIImage and UILabel are getting pushed up off of the screen. I am thinking this has to do with the UIScrollView but I haven't been able to figure out why. Thanks!

• Stop default hashtag behavior with jquery

  - by scatteredbomb

  I'm using the following code to append a hashtag to the end of a url. That way someone can copy that url and take them back to that page, with certain divs visable. $("a.live").click(function() { window.location.hash = 'live'; $("#live).slideDown(); }); In this example I have a div called 'live', that would slideDown when a link is clicked, and '#live' added to the url. Then I have code that checks the hash tags when the page is loaded to show the proper divs. My problem is, how do I prevent the browser from jumping to the 'live' div once it's called? I don't want the page to scroll down to the div, just want it opened and the hashtag appended so a person could copy it and come back to that page with that div showing. Any tips? Thank you!

• How to load / open / suck an repository from GitHub into GitX?

  - by mystify

  I downloaded Git and GitX for mac and installed it. Now, just for fun, I want to know how I could obtain an repository from GitHub like http://github.com/zoul/Finch.git ?? For me all this Git stuff looks like I have a client and connect to a server in order to get some data from some repository. Like FTP, well not really. But similar. Just one problem: Where to enter that URL? Is there some field for that? Some hidden command? I did manage to create a new project / repository on my mac, but now I have an empty window and no option to suck down that code from GitHub.

• Best design for generating code from an AST?

  - by Sam Washburn

  I'm working on a pretty complex DSL that I want to compile down into a few high level languages. The whole process has been a learning experience. The compiler is written in java. I was wondering if anyone knew a best practice for the design of the code generator portion. I currently have everything parsed into an abstract syntax tree. I was thinking of using a template system, but I haven't researched that direction too far yet as I would like to hear some wisdom first from stack overflow. Thanks!
