• Redirects in RoR: Which one to use out of redirect_to and head :moved_permanently?

  - by scrr

  Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

• Avoiding "variable might not have been initialized"

  - by Mason Wheeler

  I recently ran across a routine that looks something like this: procedure TMyForm.DoSomething(list: TList<TMyObject>; const flag: boolean); var local: integer; begin if flag then //do something else local := ExpensiveFunctionCallThatCalculatesSomething; //do something else for i := 0 to list.Count do if flag then //do something else if list[i].IntValue > local then //WARNING HERE //do something else end; This gives Variable 'local' might not have been initialized even though you can tell by reading the code that you won't hit that line unless the code branch that initializes it has run. Now, I could get rid of this warning by adding a useless local := 0; at the top of the procedure, but I wonder if there might not be a better way to structure this to avoid the issue. Anyone have any ideas?

Any suggest on the url patterns?

• Maintaining sort order of database table rows

  - by Lox

  Say I have at database table containing information about a news article in each row. The table has an integer "sort" column to dictate the order in which the articles are to be presented on a web site. How do I best implement and maintain this sort order. The problem I want to avoid is having the the articles numbered 1,2,3,4,..,100 and when article number 50 suddenly becomes interesting it gets its sort number set to 1 and then all articles between them must have their sort number increased by one. Sure, setting initial sort numbers to 100,200,300,400 etc. leaves some space for moving around but at some point it will break. Is there a correct way to do this, maybe a completely different approach? Added-1: All article titles are shown in a list linking to the contents, so yes all sorted items are show at once. Added-2: An item is not necessarily moved to the top of the list; any item can be placed anywhere in the ordered list.

If I put them in the constructor1, how can I call constructor1 in constructor2? I don't want to rewrite the initialization statements in constructor2 again. Thanks!

• DVD drive not recognized

  - by David Oneill

  I'm in the midst of building a computer (first time builder) I got everything plugged in, and hit the power button. After the excitement of the first boot coming up on my screen, I was looking through the BIOS settings. However, joy soon turned sour, as I looked at the list of installed SATA devices. My DVD drive wasn't on the list :( So, what are common things I should check/try?

• Is there a web site where I can paste a SQL Insert statement and have it break it out by column?

  - by Scott Whitlock

  I've been working on an application that has no discernable data access layer, so all the SQL statements are just built up as strings and executed. I'm constantly confronted by very long INSERT statements where I'm trying to figure out what value in the VALUES list matches up with what column in the column name list. I was about to create a little helper application where I could paste in an INSERT statement and have it show me a list of values matched up with the column names, just for debugging, and I thought, "someone else has probably done this already." Does anyone know of a web site where I can just paste in an INSERT statement and have it show me a two column table with column names in the first column and values in the second column?

• Javascript form validation/sanitizing do i need regex here ?

  - by user318144

  I have a single form input that is for checking domains. Sometimes people type in www. before the domain or .com after the domain name. The service that i use to check availability automatically checks for all top level domains so when people add the .com at the end it becomes redundant. For example the string submitted is domainname.com.com which is clearly invalid. I understand you can do this on the server side but due to some rather weird circumstance i must use javascript for this. So is regex the solution here ? If so is there some kind of regex generator i can use for this or can someone point me in the right direction with a code snippet perhaps ? Appreciate any help thanks!

• Best evidence to offer a sandboxed appdomain for a C# evaluator.

  - by scope-creep

  I have a c# evaluator which uses the (I think) the .Net 4 new simplified sandboxed appdomain model to host the c# assembly, with remoting doing the rest. The call to create the appdomain is Evidence ev = new Evidence(); ev.AddHostEvidence(new Zone(SecurityZone.Trusted)); PermissionSet pset = SecurityManager.GetStandardSandbox(ev); AppDomainSetup ads = new AppDomainSetup(); ads.ApplicationBase = "C:\\Sandbox"; // Create the sandboxed domain. AppDomain sandbox = AppDomain.CreateDomain( "Sandboxed Domain", ev, ads, pset, null); The c# eval is embedded in a server app, but I don't want give the sandbox to much control unless it bo bo's the caller. What i'm looking for is regarding some clarification as to what to provide as Evidence from the caller. I'm looking for advice and guidance. Any help would be appreciated.

• SDK Facebook app - allow to use the app only on FB, not on my website

  - by user984621

  I am newbie in creating apps for Facebook and I would like to ask you about a few things. I created my first app, in the settings I set up the domain URL, canvas URL, etc... when I load the app via apps.facebook.com/my_app_name the app is working, but also when I visit the page via the canvas URL I configured. Is there any way to only allow access to the app only when loaded inside the Facebook chrome? Also, in the app that I made are some links, buttons, etc. and when you hover over them with the mouse you can see my own domain in the status bar below. Is there a way to change that?

• Can jQuery UI's Sortable handle complex selectors for the items option?

  - by jverdi

  I have list items in an unordered list that when double clicked, can be edited in place via a wysiwyg editor. $('ul.mtm_section').sortable({ disabled: true, distance: 10, items: '> li:not(:has(form))' }); My goal is to prevent the list item from being sorted while it is being edited - aka once a form element has been swapped in place of the contents. Unfortunately my selector for items is not working. Is sortable able to handle complex selectors like these? If not, are there other clever means to disable some items from being sortable, perhaps a callback function? I would prefer to rely on this sortable option, as the wysiwyg plugin is deeply nested with jEditable and as far as I know does not open up any events for me to hook into. Using jQuery 1.4.2 and jQuery UI 1.8.1

• How do you write an idiomatic Scala Quicksort function?

  - by Don Mackenzie

  I recently answered a question with an attempt at writing a quicksort function in scala, I'd seen something like the code below written somewhere. def qsort(l: List[Int]): List[Int] = { l match { case Nil => Nil case pivot::tail => qsort(tail.filter(_ < pivot)) ::: pivot :: qsort(tail.filter(_ >= pivot)) } } My answer received some constructive criticism pointing out that List was a poor choice of collection for quicksort and secondly that the above wasn't tail recursive. I tried to re-write the above in a tail recursive manner but didn't have much luck. Is it possible to write a tail recursive quicksort? or, if not, how can it be done in a functional style? Also what can be done to maximise the efficiency of the implementation? Thanks in advance.

• How to specify a maven repository

  - by swingfuture

  I am taking over a project left by previous colleague. The project is mavenized and I'm having a hard time building it. There is a inside block, which generates error when I ran mvn install. The error shows that plugin cannot be found in maven central repo. I checked and it's not there. I happened to find another internal repository that has the plugin jar file. So outside the block, I specified a to point at that internal repo. However, when I ran mvn install again, it still goes to maven central repo to look for the plugin. How do I make it look for the jar file at the right repo? I thought by specifying the list, it would automatically check that list? Other than the repo I added, there was no repository list set up previously.

• saving values of editText in replaced fragment

  - by Eppo

  I have a 2 fragment layout, on the left fragment, i have a list of the different table names, on the right, i open up a different table depending on what is clicked on the right fragment. my intention, is that the first list item is clicked, then values will be entered on the table, next the second list item is clicked, the next table opens up and those values are entered. what would be the best way to store the values of the results entered in the editboxes, so i can process them all at once? I'm sure i can use onPause to save them all, but would that be the best way? Thanks

• JQuery: which element was clicked?

  - by centr0

  I have a list with links. These links are links to tables on the same page. What I want to do is whatever link I click in the list it will show its corresponding table and hide all the others. Without adding a different id/class to each link in the list and its corresponding table, is there a way to find out which element was clicked and show() its table? From what I understand JQuery returns an array object on its selector. How can I find out what element of the array was clicked? I've tried to use event.which but I'm a little lost. Help is greatly appreciated!

• RewriteRule being greedy

  - by lardlad

  I have been looking for an answer for a few hours now, so sorry if this was asked a ton of times, I missed it. I basically want to make a rewrite to ignore the first directory. That first dir in the path will be different so I thought I could use a regex. But my regex is matching all the way to the file name: RewriteRule ^([a-z]+)?/(.+)$ $2 [L] this works if I am one level deep: http://test.domain.com/one/index.php I get the actual index page of the root. Which is what I want. but if I were to go deeper: http://test.domain.com/one/two/index.php I get a message saying /index.php was not found. So it seems my regex is not stopping after the last [a-z]. I appreciate any help. This is Apache2 if that matters at all.

• Facebook Api - Local development, Testserver, Liveserver ... How?

  - by Thijs Kaspers

  I'm working on a new website that uses the Facebook API for users to login and several implementations of the graph Api. My workflow usually is: Development on localhost Development using MAMP/XAMPP or similar software Push to server - testing domain A team of people can test the changes for a few days to see if everything works as planned. Push to server - live domain Changes are live for public Facebook uses the site URL in the appsettings and for security reasons, they will only redirect to that url... Problem is.. I have localhost and 2 different domains. How can I make this work? Ofcourse I could edit the hostsfile, but that only fixes it for localhost.. Still no solution for the testdomain. Please tell me this is somehow possible! I'm getting more and more depressed with the Facebook API.
