• Is there a semantic difference <span>'s and <div>'s?

  - by DavidR

  I know when coding HTML, I'm supposed to keep semantics in mind, e.g., h1 needs to be a main header, h2 needs to be a subheader, tables need to be tables, use <em> for emphasis instead of <i>, etc. Is there a proper difference between divs and spans except one is a block and the other is in-line? When I was learning I was told that <span>'s were for styling text mid-line. If I had a small blurb of text that I needed positioned at a certain point in my webpage, one that doesn't warrent a <p> tag, would I use a span should I stick with div's? What if that text needs to cover two lines (i.e., it needs a width) if it contains nothing but text, what should I use?

• Controller not accepting params value but the same value hard coded is accepted

  - by Numbers

  Rails.logger.info(params[:question]) => {"title"=>"katt"} @question_list.questions.create(params[:question]) => ActiveModel::ForbiddenAttributesError (ActiveModel::ForbiddenAttributesError) @question_list.questions.create("title"=>"katt") # SUCCES! I cannot understand why Rails not accepts the params when the exact same value written by hand works fine? Update controller: def new_question @question_list.questions.create(params[:question]) render nothing: true end private def set_question_list @question_list = QuestionList.find(params[:id]) end def question_list_params params.require(:question_list).permit(questions_attributes: [:id, :question_list_id, :title, :position, :_destroy]) end view: <%= form_for @question_list, url: new_question_question_list_path, remote: true do |f| %> <%= f.text_field :title %> <%= f.submit %> <% end %>

• Automating SSRS Report Deployment

  - by MikeTWebb

  Hello....I have a web site in 3 environments (DEV/TEST/PROD). The Web Site uses SSRS which also has 3 different environments(DEV/TEST/PROD). Currently, I am deploying the reports using the Manual Deployment mechanism provided in the SSRS Solution (i.e., right click a report and click "Deploy"). I have to manually change the Deployment URLs for each environment. Is there a way to Automate this so that reports are automatically deployeed to PROD and TEST if a change occurs in DEV? I've seen some info on RSScripter but it looks a little tricky/clunky...I was hoping for a more succinct/streamlined solution. Thanks MikeTWebb

• changing order of items in tkinter listbox

  - by user1104854

  Is there an easier way to change the order of items in a tkinter listbox than deleting the values for specific key, then re-entering new info? For example, I want to be able to re-arrange items in a listbox. If I want to swap the position of two, this is what I've done. It works, but I just want to see if there's a quicker way to do this. def moveup(self,selection): value1 = int(selection[0]) - 1 #value to be moved down one position value2 = selection #value to be moved up one position nameAbove = self.fileListSorted.get(value1) #name to be moved down nameBelow = self.fileListSorted.get(value2) #name to be moved up self.fileListSorted.delete(value1,value1) self.fileListSorted.insert(value1,nameBelow) self.fileListSorted.delete(value2,value2) self.fileListSorted.insert(value2,nameAbove)

• efficiently trimming postgresql tables

  - by agilefall

  I have about 10 tables with over 2 million records and one with 30 million. I would like to efficiently remove older data from each of these tables. My general algorithm is: create a temp table for each large table and populate it with newer data truncate the original tables copy tmp data back to original tables using: "insert into originaltable (select * from tmp_table)" However, the last step of copying the data back is taking longer than I'd like. I thought about deleting the original tables and making the temp tables "permanent", but I lose constraint/foreign key info. If I delete from the tables directly, it takes much longer. Given that I need to preserve all foreign keys and constraints, are there any faster ways of removing the older data? Thanks.

• iPhone: Waiting until selectrow animation finishes before pushing viewcontroller?

  - by Mike

  My code looks like this: NSIndexPath *ip = [NSIndexPath indexPathForRow:15 inSection:0]; [[self tableView] selectRowAtIndexPath:ip animated:YES scrollPosition:UITableViewScrollPositionMiddle]; // Pause needed here until animation finishes [[self navigationController] pushViewController:secondView animated:YES]; Right now it animates the scroll/selection of the row and pushes the view controller at the same time. What I would like it to do is wait until it finishes the scroll/selection and then push the view controller. Is there any possible way of doing this? Thanks

• How do I keep a count of undefined strings within a loop using PHP?

  - by mike

  I'm using a loop within a loop to try to generate keyword combinations and also find the ones that have been used the most. My outside loop just queries a list of keywords (lets use "chicago" as our first keyword, 3 records were found). The inside loop finds all the records in the "posts" table where keyword = "chicago". Within this loop, I need to generate strings based on info I found in the database. Which, would look something like "chicago bulls", "chicago bears", "chicago cubs" etc... I know how to do everything up until this point, but how do I temporary hold these generated strings and count how many times they have been found within the 3 records?

• Efficient way to combine results of two database queries.

  - by ensnare

  I have two tables on different servers, and I'd like some help finding an efficient way to combine and match the datasets. Here's an example: From server 1, which holds our stories, I perform a query like: query = """SELECT author_id, title, text FROM stories ORDER BY timestamp_created DESC LIMIT 10 """ results = DB.getAll(query) for i in range(len(results)): #Build a string of author_ids, e.g. '1314,4134,2624,2342' But, I'd like to fetch some info about each author_id from server 2: query = """SELECT id, avatar_url FROM members WHERE id IN (%s) """ values = (uid_list) results = DB.getAll(query, values) Now I need some way to combine these two queries so I have a dict that has the story as well as avatar_url and member_id. If this data were on one server, it would be a simple join that would look like: SELECT * FROM members, stories WHERE members.id = stories.author_id But since we store the data on multiple servers, this is not possible. What is the most efficient way to do this? Thanks.

• Python: Data Object or class

  - by arg20

  I enjoy all the python libraries for scraping websites and I am experimenting with BeautifulSoup and IMDB just for fun. As I come from Java, I have some Java-practices incorporated into my programming styles. I am trying to get the info of a certain movie, I can either create a Movie class or just use a dictionary with keys for the attributes. My question is, should I just use dictionaries when a class will only contain data and perhaps almost no behaviour? In other languages creating a type will help you enforce certain restrictions and because of type checks the IDE will help you program, this is not always the case in python, so what should I do? Should I resort to creating a class only when there's both, behaviour and data? Or create a movie class even though it'll probably be just a data container? This all depends on your model, in this particular case either one is fine but I'm wondering about what's a good practice.

• How does the dispatch action call work in the Twitter sidebar

  - by phwd

  I would like to understand how the call for replies works as follows: <a href="http://twitter.com/replies" data="{"dispatch_action":"replies"}"> <span>@phwd</span> </a> This was taken from the homepage of Twitter. The section in particular being: data="{"dispatch_action":"replies"}" I believe (think), it is using Twitter's own twitter.js script and I do not want to interfere(or copy) with their code, I rather just want to know how the call works. My current setup is using Abraham's twitteroauth PHP library, jQuery and some Ajax to refresh the portion of the page needed using the following method : Use jQuery and PHP to build an Ajax-driven Web page [IBM link - I am a new user so I can only post one link] I apologize if this question is not formatted/worded well, it is my first time. Also I tried searching DocType and StackOverFlow. The Related Questions show me Struts but I am not sure it is that.

• Need some advice on a language to use for a 'presentation display board'

  - by joe90

  As part of the project i am working on I am looking to produce some software that works on a LCD display (think call center info boards) and displays various graphs (the bars grow etc in realtime, so incoming call stats etc etc) and flicks between various 'plug-ins'. The problem is deciding what language to use.. I am thinking about using the XNA framework, as this will allow me to do some nice 3d effects, add a nice glow effect, play videos etc. I can have for example the company logo defused spinning slowly behind the current data display. I know however, the XNA framework is a bit left field for this. Or is there a better alternative? Thanks..

• javascript window.close, once again

  - by John Kjøller

  Im sorry if I havent done my research properly, - but couldnt find the answer I needed, so here goes: From my main page I open a new window using mainPlayer = window.open(); This window stays open until user clicks on a mainPlayer.close(); event. (or simply x closes the window) However, the idea is to make it possible to let the player keep playing, while browsing around the rest of the pages. But as soon as the user leaves the page that opened the mainPlayer window, the reference to the mainPlayer window seem to be lost. How do I, from the site's other pages, check if the mainPlayer window is open and close it on a click event? Thx John

• populate a listbox from a.. function?

  - by andrew

  hello first of all i'm kinda new to C# I'm trying to do something like this in a C# winforms application when my app starts, a form starts minimized in the system tray. when i double click it, it opens and sends a request to a qpid broker for some info. then a message is sent back, and received in a listener in my app (i'm not sure code is relevant but i'll post it anyway) namespace MyApp { public class MyListener : IMessageListener { public void MessageTransfer(IMessage m) { //do stuff with m } } } what i'm trying to do is populate a listbox that's in that form with the message received in that function, but i have no idea how to communicate with that specific form from the MessageTransfer function

• Did the OS X java update to 1.5u7 whack my 1.6.0 laf.jar?

  - by Brian Deacon

  This is the update that just came out this week (2010-05-18) Somebody moved my cheese. It appears that laf.jar is Look And Feel, so probably not a big deal for my java development. Eclipse got mad about the missing jar, and furthermore thinks the 1.6.0 VM disappeared, which it didn't. Had to redefine the VM library within eclipse and everything appears kosher, but was hoping somebody with more hit points than me could say so definitively. Am I all good? Was it really the OSX update for 1.5 that went and hunted down a file in my 1.6 VM? Haven't been able to google anything about this... if somebody could post a link to some info about this, that'd be appreciated too.

• mysql inserts & updates optimized

  - by user271619

  This is an optimization question, mostly. I have many forms on my sites that do simple Inserts and Updates. (Nothing complicated) But, several of the form's input fields are not necessary and may be left empty. (again, nothing complicated) However, my SQL query will have all columns in the Statement. My question, is it best to optimize the Inserts/Update queries appropriately? And only apply the columns that are changed into the query? We all hear that we shouldn't use the "SELECT *" query, unless it's absolutely needed for displaying all columns. But what about Inserts & Updates? Hope this makes sense. I'm sure any amount of optimization is acceptable. But I never really hear about this, specifically, from anyone.

• Cannot add an icon to Resources

  - by Stanley

  Have been inputting and testing some sample code and everything seems to be ok. Just that suddenly I am running into this very frustrating problem of trying to add an icon to the project. Have downloaded an icon file (extension : icns) to my desktop and dragged it to the "Resources" group in xCode. Then a dialogue comes up from xCode where I checked the 2 options : "Copy items into destination group's folder (if needed)" and "Recursively create groups for any added folders". But when I press the "Add" button, an "Alert" message box would come up. It says "Could not copy the icon to ...". Hope that someone knowledgable in this area would give me some hints...

• Why use a do-end block in Lua?

  - by Mayron

  I keep trying to find answers for this but fail to do so. I wanted to know, what is the do-end block actually used for? It just says values are used when needed in my book so how could I use this? Do I use it to reduce the scope of local variables by placing a function in a do-end loop and place local variables outside of the function but inside this do-end block and the variables will be seen by the function? But then can the function still be called? Sorry for being very vague. I hope that makes sense. Maybe an illustrated example might be useful ^^

• Write to a binary file?

  - by rick irby

  Here is data structure w/ variables: struct Part_record { char id_no[3]; int qoh; string desc; double price: }; --- (Using "cin" to input data) --- Part_record null_part = {" ", 0," ",0.0}; --- --- file.seekg( -(long)sizeof(Part_record), ios::cur); file.write( ( char *)&part, sizeof(Part_record) ); The three variables, qoh, Id_no & price, write out correctly, but the "desc" variable is not right. Do I need to initialize Part_record some other way? It should be 20 characters in length. If you have enough info here, pls share your advice,thanks.

• Which JavaScript Libraries do not rely on a document and navigator object?

  - by Julian Weimer

  I'm currently looking for some libraries which might help me during iPhone Development using Appcelerator Titanium. I've heard that since version 1.0 it isn't dependant on webkit anymore and it makes app-development more exiting of course, please correct me if i'm wrong. As many people out there i love Javascript Frameworks such as JQuery and Mootools much, but they were build specifically to do a great job within a browser and most of the functionality is not needed within the environment Titanium now provides (DOM-Manipulation etc). Is there any other small library of useful functions i can use for development? Thx in advance.

• How to get ListView to grow to the size of content

  - by Jared

  So I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use? I'm open to any ideas. I really just don't know how to go about this. Thanks

• What is the right way to pass class parameters to a method

  - by Schneider

  Let's suppose I have three classes A, B and C public class A { public int A1; public string A2; } public class B { public char B1; public double B2; public decimal B3; } public class C { public string DoSomething(A a, B b) { var a1 = a.A1; var b2 = b.B2; var b3 = b.B3; // DoSomething return string.Empty; } } If DoSomething() is using just some fields of the A and B classes, do you prefer to pass the whole object in parameters or create an intermediate class that has just the needed fields by the DoSomething method ?

• Dynamic Button Layout without hard coding positions

  - by mmc

  I would like to implement a view (it will actually be going into the footer of a UITableView) that implements 1-3 buttons. I would like the layout of these buttons (and the size of the buttons themselves) to change depending on which ones are showing. An example of almost the exact behavior I would want is at the bottom of the Info screen in the Contacts application when you are looking at a specific contact ("Add to Favorites" disappears when it is clicked, and the other buttons expand to take up the available space in a nice animation). As I'm running through the different layout scenarios, I'm hard coding all these values and I just think... "this is NOT the way I'm supposed to be doing this." It even APPEARS that Interface Builder has some features that may do this for me in the ruler tab, but I'll be darned if I can figure out how they work (if they work) on the phone. Does anyone have any suggestions, or a tutorial online that I could look at to point me in the right direction? Thanks much.
