• is it possible to make one click fires two events or more by javascript?

  - by NewInAlbert

  I am currently making a temporary download page for website visitor. The page includes a form, after the visitor fills the form up, the site will take them to the pdf download page. In the download page, there are some pdf files download links (I am just using a tag.). However, i wanna make a onclick event to those links, once they have been clicked, the page will refresh automatically or redirect to other pages. <a href="/file.pdf" onClick="window.location.reload()">The File</a> I have tried the jquery way as well. <a href="/file.pdf" id="FileDownload">The File</a> <script> $("#FileDownload").click(function(){ location.reload(); }); </script> But all the them are not working. Do you masters have any good ideas about this, many thanks. P.S. What if I wanna add a countdown after a file is being started download, and then do page reload when countdown finishes. Looks like have asked several questions... Thanks a ton in advance.

• Evaluating creation of GUI via file vs coding

  - by nevets1219

  I'm working on a utility that will be used to test the project I'm currently working on. What the utility will do is allow user to provide various inputs and it will sends out requests and provide the response as output. However, at this point the exact format (which input is required and what is optional) has yet to be fleshed out. In addition, coding in Swing is somewhat repetitive since the overall work is simple though this should be the safest route to go as I have more or less full control and every component can be tweaked as I want. I'm considering using a configuration file that's in XML to describe the GUI (at least one part of it) and then coding the event handling part (in addition to validation, etc). The GUI itself shouldn't be too complicated. For each type of request to make there's a tab for the request and within each tab are various inputs. There seems to be quite a few questions about this already but I'm not asking for a 3rd party library to do this. I'm looking to do this myself, since I don't think it'll be too overly complicated (hopefully). My main consideration for using this is re-usability (later on, for other projects) and for simplifying the GUI work. My question is: are there other pros/cons that I'm overlooking? Is it worth the (unknown) time to do this? I've built GUI in VB.NET and with Flex3 before.

• Alternate colors on click with jQuery

  - by Jace Cotton

  I'm sure there is a simple solution to this, and I'm sure this is a duplicate question, though I have been unable to solve my solution particularly because I don't really know how to phrase it in order to search for other questions/solutions, so I'm coming here hoping for some help. Basically, I have spans with classes that assigns a background-color property, and inside those spans are words. I have three of these spans, and each time a user clicks on a span I want the class to change (thus changing the background color and inner text). HTML: <span class="alternate"> <span class="blue showing">Lorem</span> <span class="green">Ipsum</span> <span class="red">Dolor</span> </span> CSS: .alternate span { display : none } .alternate .showing { display : inline } .blue { background : blue } .green { background : green } .red { background : red } jQuery: $(".alternate span").each(function() { $(this).on("click", function() { $(this).removeClass("showing"); $(this).next().addClass("showing"); }); }); This solution works great using $.next until I get to the third click, whereafter .showing is removed, and is not added since there are no more $.next options. How do I, after getting to the last-child, add .showing to the first-child and then start over? I have tried various options including if($(".alternate span:last-child").hasClass("showing")) { etc. etc. }, and I attempted to use an array and for loop though I failed to make it work. Newb question, I know, but I can't seem to solve this so as a last resort I'm coming here.

• Security of Flex for payment website

  - by Mario

  So, it's been about 3 years since I wrote and went live with my company's main internet facing website. Originally written in php, I've since just been making minor changes here and there to progress the site as we've needed to. I've wanted to rewrite it from the ground up in the last year or so and now, we want to add some major features so this is a perfect time. The website in question is as close to a banking website as you'd get (without being a bank; sorry for the obscurity, but the less info I can give out, the better). For the rewrite, I want to separate the presentation layer from the processing layer as much as I can. I want the end user to be stuck in a box and not be able to get out so to speak (this is all because of PCI complacency, being PEN tested every 3 months, etc...) So, being probed every 3 months has increasingly made me nervous. We haven't failed yet and there hasen't been a breach yet, but I want to make sure I continue to pass (as much as I can anyways) So, I'm considering rewriting the presentation layer in Adobe Flex and do all the processing in PHP (effectively IMO, separating presentation from processing) - I would do all my normal form validation in flex (as opposed to javascript or php) and do my reads and writes to the db via php. My questions are: I know Flash has something like 99% market penetration - do people find this to be true? Has anyone seen on their own sites being in flash that someone couldn't access it? Flash in general has come under alot of attacks about security and the like - i know this. I would use a swf encryptor - disable debugging (which i got snagged on once on a different application), continue to use https and any other means i can think of. At the end of the day, everyone knows if someone wants in to the data bad enough, their going to find a ways in; i just wanna make it as difficult for them as i can. Any thoughts are appreciated. -Mario

• LINQ to SQL - Lightweight O/RM?

  - by CoffeeAddict

  I've heard from some that LINQ to SQL is good for lightweight apps. But then I see LINQ to SQL being used for Stackoverflow, and a bunch of other .coms I know (from interviewing with them). Ok, so is this true? for an e-commerce site that's bringing in millions and you're typically only doing basic CRUDs most the time with the exception of an occasional stored proc for something more complex, is LINQ to SQL complete enough and performance-wise good enough or able to be tweaked enough to run happily on an e-commerce site? I've heard that you just need to tweak performance on the DB side when using LINQ to SQL for a better approach. So there are really 2 questions here: 1) Meaning/scope/definition of a "Lightweight" O/RM solution: What the heck does "lightweight" mean when people say LINQ to SQL is a "lightweight O/RM" and is that true??? If this is so lightweight then why do I see a bunch of huge .coms using it? Is it good enough to run major .coms (obviously it looks like it is) and what determines what the context of "lightweight" is...it's such a generic statement. 2) Performance: I'm working on my own .com and researching different O/RMs. I'm not really looking at the Entity Framework (yet), just want to figure out the LINQ to SQL basics here and determine if it will be efficient enough for me. The problem I think is you can't tweak or control the SQL it generates...

• codeigniter differentiate field names in JOINed tables

  - by Patrick

  Hi, I need to retrieve data from two tables. the first is a list of events, the second is a list of venues. I have a fields with the same name in both tables: events.venue (which is an ID) and venues.venue is the name of the place, say "blues bar". The tables can be joined on events.venue = venues.id. Snippet of my model: $this->db->select('events.*, venues.*'); $this->db->join('venues', 'events.venue = venues.id'); if ($date != 'all') { $this->db->where('date', $date); } if ($keyword) { $this->db->like('description', $keyword); $this->db->or_like('band', $keyword); $this->db->or_like('venue', $keyword); $this->db->or_like('genre', $keyword); } $Q = $this->db->get('events'); if ($Q->num_rows() > 0) { foreach ($Q->result() as $row) { $data[] = $row; } } $Q->free_result(); return $data; Snippet of the View: foreach ($events as $row) { echo "<p>{$row->band} ({$row->genre})<br />"; echo "Playing at: {$row->venue}<br /></p>"; // echoes "blues bar" //more here... } 2 Questions: 1) Why does $row-venue echo venues.venue, instead of events.venue? B) how can I differentiate them? eg. What if I want to echo both events.venue and venues.venue? I can probably do something like "SELECT venues.venue as name_of_the_venue", but how can I do this when I've already selected *?

• Whether to put method code in a VB.Net data storage class, or put it in a separate class?

  - by Alan K

  TLDR summary: (a) Should I include (lengthy) method code in classes which may spawn multiple objects at runtime, (b) does doing so cause memory usage bloat, (c) if so should I "outsource" the code to a class that is loaded only once and have the class methods call that, or alternatively (d) does the code get loaded only once with the object definition anyway and I'm worrying about nothing? ........ I don't know whether there's a good answer to this but if there is I haven't found it yet by searching in the usual places. In my VB.Net (2010 if it matters) WinForms project I have about a dozen or so class objects in an object model. Some of these are pretty simple and do little more than act as data storage repositories. The ones further up the object model, however, have an increasing number of methods. There can be a significant number of higher level objects in use though the exact number will be runtime dependent so I can't be more precise than that. As I was writing the method code for one of the top level ones I noticed that it was starting to get quite lengthy. Memory optimisation is something of a lost art given how much memory the average PC has these days but I don't want to make my application a resource hog. So my questions for anyone who knows .Net way better than I do (of which there will be many) are: Is the code loaded into memory with each instance of the class that's created? Alternatively is it loaded only once with the definition of the class, and all derived objects just refer to that definition? (I'm not really sure how that could be possible given that, for example, event handlers can be assigned dynamically, but no harm asking.) If the answer to the first one is yes, would it be more efficient to write the code in a "utility" object which is loaded only once and called from the real class' methods? Any thoughts appreciated.

• JQuery quiz app - use <id> tag to toggle variable on/off

  - by hairyllama

  Hi, I am writing a jquery phonegap quiz app and have a number of categories from which a user can select via checkbox. Relevant questions belonging to those categories are then returned. However, I have two huge switch statements to change the relevant variables from 0 to 1 if the checkbox for that category is selected and vice versa (this info is used to build a compound db query). The value of the variable behind the checkbox is only ever 0 or 1, so is there a better way to do this? My HTML is: <h2>Categories</h2> <ul class="rounded"> <li>Cardiology<span class="toggle"><input type="checkbox" id="cardiology" /></span></li> <li>Respiratory<span class="toggle"><input type="checkbox" id="respiratory" /></span></li> <li>Gastrointestinal<span class="toggle"><input type="checkbox" id="gastrointestinal" /></span></li> <li>Neurology<span class="toggle"><input type="checkbox" id="neurology" /></span></li> </ul> My Javascript is along the lines of: var toggle_cardiology = 0; var toggle_respiratory = 0; var toggle_gastrointestinal = 0; var toggle_neurology = 0; $(function() { $('input[type="checkbox"]').bind('click',function() { if($(this).is(':checked')) { switch (this.id) { case "cardiology": toggle_cardiology = 1; break; case "respiratory": toggle_respiratory = 1; break; case "gastrointestinal": toggle_gastrointestinal = 1; break; case "neurology": toggle_neurology = 1; break; etc. (which is cumbersome with 10+ categories plus an else statement with a switch to change them back) I'm thinking of something along the lines of concatenating the HTML id tag onto the "toggle_" prefix - in pseudocode: if (toggle_ + this.id == 1){ toggle_ + this.id == 0} if (toggle_ + this.id == 0){ toggle_ + this.id == 1} Thanks, Nick.

• Populate JOIN into a list in one database query

  - by axio

  I am trying to get the records from the 'many' table of a one-to-many relationship and add them as a list to the relevant record from the 'one' table. I am also trying to do this in a single database request. Code derived from http://stackoverflow.com/questions/1580199/linq-to-sql-populate-join-result-into-a-list almost achieves the intended result, but makes one database request per entry in the 'one' table which is unacceptable. That failing code is here: var res = from variable in _dc.GetTable<VARIABLE>() select new { x = variable, y = variable.VARIABLE_VALUEs }; However if I do a similar query but loop through all the results, then only a single database request is made. This code achieves all goals: var res = from variable in _dc.GetTable<VARIABLE>() select variable; List<GDO.Variable> output = new List<GDO.Variable>(); foreach (var v2 in res) { List<GDO.VariableValue> values = new List<GDO.VariableValue>(); foreach (var vv in v2.VARIABLE_VALUEs) { values.Add(VariableValue.EntityToGDO(vv)); } output.Add(EntityToGDO(v2)); output[output.Count - 1].VariableValues = values; } However the latter code is ugly as hell, and it really feels like something that should be do-able in a single linq query. So, how can this be done in a single linq query that makes only a single database query? In both cases the table is set to preload using the following code: _dc = _db.CreateLinqDataContext(); var loadOptions = new DataLoadOptions(); loadOptions.LoadWith<VARIABLE>(v => v.VARIABLE_VALUEs); _dc.LoadOptions = loadOptions; I am using .NET 3.5, and the database back-end was generated using SqlMetal.

• Practicing inserting data into an array by using binary search, few problems

  - by HelpNeeder

  I'm trying to create a method which inserts and then sort elements in form of binary form. The problem I am experiencing that my code doesn't insert data correctly which means that output does not appear to be in order at all. The list is not organized, and data is added in order that is being inserted. Now, 2 questions, what am I doing wrong here? And how to fix this? public void insertBinarySearch(long value) // put element into array { int j = 0; int lower = 0; int upper = elems-1; int cur = 0; while (cur < elems) { curIn = (lower + upper ) / 2; if(a[cur] < value) { j = cur + 1; break; } else if(a[cur] > value) { j = cur; break; } else { if(a[cur] < value) lower = cur + 1; else upper = cur - 1; } } for(int k = elems; k > j; k--) a[k] = a[k-1]; a[j] = value; elems++; }

• Should I go to school and get my degree in computer science?

  - by ryan

  I'll try and keep this short and simple. I've always enjoyed programming and I've been doing it since high school. Right after I graduated from high school (2002), I opted to skip college because I was offered a software engineer position. I quit after a couple of years later to team up on various startup companies. However, most of them did not launch as well as expected. But it honestly did not matter to me because I've learned so much from that experience. So fast forwarding to today, now turned 25, I need a job due to this tough economic climate. Looking on Craigslist, a lot of the listings require computer science degrees. It's evident now that programming is what I want to do because I seem to never get enough of it. But just the thought of having to push 2 years without attending any real computer class for an Associates at age 25 is very, very discouraging. And the thought of having to learn from basic (Hello WOOOOORRLLLD) just does not seem exciting. I guess I have 3 questions to wrap this up: Should I just suck it up and go back to school while working at McDonalds at age 25? Is there a way where I can just skip all the boring stuff and just get tested with what I know? From your experience, how many jobs use computer science degrees as prerequisites? Or am I screwed and better pray that my next startup will be the next big thing?

• How to access frame (not iframe) contents from jQuery.

  - by kazanaki

  Hello I have 2 frames in one page like this (home.html) <frameset rows="50%, 50%"> <frame id="treeContent" src="treeContent.html" /> <frame id="treeStatus" src="treeStatus.html" /> </frameset> and then in one frame (treeStatus.html) I have something like <body style="margin: 0px"> <div id="statusText">Status bar for Tree</div> </body> I want from the top window to manipulate the div located in the child frame via jquery (e.g show and hide). I have seen several questions like this and they suggest the following $(document).ready(function(){ $('#treeStatus').contents().find("statusText").hide(); }); I do not know if this works with iframes but in my case where I have simple frames it does not seem to work. The code is placed inside home.html Here is some output from firebug console >>> $('#treeStatus') [frame#treeStatus] >>> $('#treeStatus').contents() [] >>> $('#treeStatus').children() [] So how do I access frame elements from the top frame? Am I missing something here?

• Including Data From DropDownList Into Gridview

  - by Mike Keller

  I feel a little embarassed posting two questions relating to the same problem, but the first one ended up answering a question that I believe is unrelated to the solution so I'm leaving it up and outlining what I'm trying to accomplish with the hopes that someone can help out a .Net noob. What I need to be able to do is create a field in my gridview that contains a link that passes two variables. One is pulled from within the gridviews datasource and the other needs to be pulled from a textbox control outside the gridview. From what I've read so far you cannot use a hyperlinkfield for this as the datanavigateurlfields cannot be set to pull from anything but the gridview's data source. What I attempted to do was create a template field where in the itemtemplate I called: <a href="example.aspx?e=<%# Eval(ExampleList.SelectedItem.Value) %>">Test</a> That comes back with an error like this: DataBinding: 'System.Data.DataRowView' does not contain a property with the value 'TestData' Any clues to make this happen would be appreciated, like I said I'm pretty new to .Net so please be gentle. I tried to do my homework before posting this.

• Pass variable by Post method from JQuery UI Autocomplete to PHP page

  - by Shahriar N Khondokar

  I have two JQuery UI autocomplete input fields. When an option is selected in the first one, the value of the selection will be used as condition for a database query that will send the source data for the second autocomplete field. My problem is how do I send the value of the first selection to the PHP page via Post method? The code so far is shown below (this code is from a tutorial which used the GET method; but I want to use Post): <script> $("input#divisions").autocomplete ({ //this is the first input source : [ { value: "81", label: "City1" }, { value: "82", label: "City2" }, { value: "83", label: "City3" } ], minLength : 0, select: function(event, ui) { $('#divisions').val(ui.item.label); return false; }, focus: function(event, ui){ $('#divisions').val(ui.item.label); return false; }, change: function(event, ui){ //the tutorial has this value sent by variables in the URL; I want the selection value sent by POST. How can I change this? c_t_v_choices = "c_t_v_choices.php?filter=" + ui.item.value; $("#c_t_v").autocomplete("option", "source", c_t_v_choices); } }).focus (function (event) { $(this).autocomplete ("search", ""); }); $("#c_t_v").autocomplete({ source: "", minLength: 2, select: function(event,ui){ //$('#city').val(ui.item.city); } }); </script> Can anyone please help? Dont hesitate to let me know if you have any questions.

• Undefined Variable? But I defined it...

  - by Rob

  Well before anyone claims that theres a duplicate question... (I've noticed that people who can't answer the question tend to run and look for a duplicate, and then report it.) Here is the duplicate you are looking for: http://stackoverflow.com/questions/2481382/php-claims-my-defined-variable-is-undefined However, this isn't quite a duplicate. It gives me a solution, but I'm not really looking for this particular solution. Here is my problem: Notice: Undefined variable: custom Now here is my code: $headers = apache_request_headers(); // Request the visitor's headers. $customheader = "Header: 7ddb6ffab28bb675215a7d6e31cfc759"; //This is what the header should be. foreach ($headers as $header => $value) { $custom .= "$header: $value"; } Clearly, $custom is defined. According to the other question, it's a global and should be marked as one. But how is it a global? And how can I make it a (non-global)? The script works fine, it still displays what its supposed to and acts correctly, but when I turn on error messages, it simply outputs that notice as well. I suppose its not currently necessary to fix it, but I'd like to anyway, as well as know why its doing this.

• MySQL: Limit rows linked to each joined row

  - by SolidSnakeGTI

  Hello, Specifications: MySQL 4.1+ I've certain situation that requires certain result set from MySQL query, let's see the current query first & then ask my question: SELECT thread.dateline AS tdateline, post.dateline AS pdateline, MIN(post.dateline) FROM thread AS thread LEFT JOIN post AS post ON(thread.threadid = post.threadid) LEFT JOIN forum AS forum ON(thread.forumid = forum.forumid) WHERE post.postid != thread.firstpostid AND thread.open = 1 AND thread.visible = 1 AND thread.replycount >= 1 AND post.visible = 1 AND (forum.options & 1) AND (forum.options & 2) AND (forum.options & 4) AND forum.forumid IN(1,2,3) GROUP BY post.threadid ORDER BY tdateline DESC, pdateline ASC As you can see, mainly I need to select dateline of threads from 'thread' table, in addition to dateline of the second post of each thread, that's all under the conditions you see in the WHERE CLAUSE. Since each thread has many posts, and I need only one result per thread, I've used GROUP BY CLAUSE for that purpose. This query will return only one post's dateline with it's related unique thread. My questions are: How to limit returned threads per each forum!? Suppose I need only 5 threads -as a maximum- to be returned for each forum declared in the WHERE CLAUSE 'forum.forumid IN(1,2,3)', how can this be achieved. Is there any recommendations for optimizing this query (of course after solving the first point)? Notes: I prefer not to use sub-queries, but if it's the only solution available I'll accept it. Double queries not recommended. I'm sure there's a smart solution for this situation. Appreciated advice in advance :)

• Problem accessing private variables in jQuery like chainable design pattern

  - by novogeek

  Hi folks, I'm trying to create my custom toolbox which imitates jQuery's design pattern. Basically, the idea is somewhat derived from this post: http://stackoverflow.com/questions/2061501/jquery-plugin-design-pattern-common-practice-for-dealing-with-private-function (Check the answer given by "David"). So here is my toolbox function: (function(window){ var mySpace=function(){ return new PrivateSpace(); } var PrivateSpace=function(){ var testCache={}; }; PrivateSpace.prototype={ init:function(){ console.log('init this:', this); return this; }, ajax:function(){ console.log('make ajax calls here'); return this; }, cache:function(key,selector){ console.log('cache selectors here'); testCache[key]=selector; console.log('cached selector: ',testCache); return this; } } window.hmis=window.m$=mySpace(); })(window) Now, if I execute this function like: console.log(m$.cache('firstname','#FirstNameTextbox')); I get an error 'testCache' is not defined. I'm not able to access the variable "testCache" inside my cache function of the prototype. How should I access it? Basically, what I want to do is, I want to cache all my jQuery selectors into an object and use this object in the future.

• C++ Returning Pointers/References

  - by m00st

  I have a fairly good understanding of the dereferencing operator, the address of operator, and pointers in general. I however get confused when I see stuff such as this: int* returnA() { int *j = &a; return j; } int* returnB() { return &b; } int& returnC() { return c; } int& returnC2() { int *d = &c; return *d; } In returnA() I'm asking to return a pointer; just to clarify this works because j is a pointer? In returnB() I'm asking to return a pointer; since a pointer points to an address, the reason why returnB() works is because I'm returning &b? In returnC() I'm asking for an address of int to be returned. When I return c is the & operator automatically "appended" c? In returnC2() I'm asking again for an address of int to be returned. Does *d work because pointers point to an address? Assume a, b, c are initialized as integers. Can someone validate if I am correct with all four of my questions?

• Converting WAR to EAR and other Glassfish stories

  - by Random

  Hello! I am really new in this so I hopefully don't make any terrible mistake. I apologize before hand if I have. In my project I was using tomcat and deploying WAR files. But now some bosses wants to deploy EAR files. So there we go. I first downloaded Glassfish (don't know if it's the apropiate application server for a newbie like me), instaled it and all (I even deployed the hello.war in the autodeploy _< ). Then prepared an EAR file. From what I know, I just need to create an Enterprise Application Project in Eclipse and add to the module my war file. This changes the application.xml file automatically (thanks eclipse project!). So I exported it to an EAR file and uploaded it to the glassfish server. Wonders of wonders, it doesn't work. I also tried deploying the old WAR file in this new shiny glassfish but it goes on http-404 not found error. The glassfish seems to say that my project is not in ~/domains/domain1/docroot. By the way I am using windows and I am aware of some problems between glassfish and windows due to some updating open files or such. So I have to questions: First, Am I doing the EAR package correctly? Second, Do I need to do some especial configuration to the glassfish server to deploy EAR and WAR files? Thanks!

• Is it still true, to make cross broswer layouts for desktop browsers using table+css is easier then

  - by metal-gear-solid

  My one of web designer friend still making sites with table but he use css very nicely and I also use css nicely but with <div> and i face cross browser problem in layout more than my friend. and i given some reason to my friend about cons of <table>. read my whole discussion with friend? I - you site will be problematic with screen reader My friend - OK, but i never got any call from any client regarding this. I - you will devote more time to make any changes in layout, if changes comes from client My friend - I don't think so, but if it is then show me how can i save time with <div>? I - your sites will not work well with search engine. My friend - it's not true. I've made many site and no problem with any site or client regarding this I - layout is old way, non w3c and non standard way. My friend - what is old and what is new, Who is W3C i don't know, What is standard? Whatever i make works in all browsers, it's enough for me and my client will not pay for standard and W3C guidelines rules I - Your site will not work in mobile browsers My friend - No problem for me, my client don't care about mobile phone I - Your sites are not accessible? My Friend - What do u mean not accessible? Whatever i make works in all browsers. my any client never asked about accessibility I - You will not get more work in future, with table? My friend - OK, no problem when clients will not accept site with table then i will learn about div based layouts in future. My questions? Is it still true, to make cross browser layouts for desktop browsers using table+css is easier then div+css? What is the benefit for developer to use DIV+CSS layout in place of <table> layouts if client would not mind if i use ?

• Grails - Where to store properties related to domains

  This is something I have been struggling about for some time now. The thing is: I have many (20 or so) static arrays of values. I say static because that is how I'm actually storing them, as static arrays inside some domains. For example, if I have a list of known websites, I do: class Website { ... static websites = ["web1", "web2" ...] } But I do this just while developing, because I can easily change the arrays if needed, but what I'm going to do when the application is ready for deployment? In my project it is very probable that, at some point, these arrays of values change. I've been researching on that matter, one can store application properties inside an external .properties file, but it will be impossible to store an array, even futile, because if some array gets an additional value, the application can't recognize it until the name of the new property is added where needed. Another approach is to store this information in the database, but for some reason it seems like a waste to add 20 or more tables that will have just two rows, an id and a name. And the last option, as far as I know, would be an XML, but I'm not very experienced with those. It seems groovy has a way of creating and reading XML files relatively easy, but I don't know how difficult would be to modify an XML whose layout is predefined in the application. Needless to say that storing them in the config.groovy is not an option since any change will require to recompile. I haven't come across some "standard" (maybe a best practice?) way of dealing with these. So the questions is: Where to store these arrays?

• Git Svn dcommit error - restart the commit

  - by Rob Wilkerson

  Last week, I made a number of changes to my local branch before leaving town for the weekend. This morning I wanted to dcommit all of those changes to the company's Svn repository, but I get a merge conflict in one file: Merge conflict during commit: Your file or directory 'build.properties.sample' is probably out-of-date: The version resource does not correspond to the resource within the transaction. Either the requested version resource is out of date (needs to be updated), or the requested version resource is newer than the transaction root (restart the commit). I'm not sure exactly why I'm getting this, but before attempting to dcommit, I did a git svn rebase. That "overwrote" my commits. To recover from that, I did a git reset --hard HEAD@{1}. Now my working copy seems to be where I expect it to be, but I have no idea how to get past the merge conflict; there's not actually any conflict to resolve that I can find. Any thoughts would be appreciated. EDIT: Just wanted to specify that I am working locally. I have a local branch for the trunk that references svn/trunk (the remote branch). All of my work was done on the local trunk: $ git branch maint-1.0.x master * trunk $ git branch -r svn/maintenance/my-project-1.0.0 svn/trunk Similarly, git log currently shows 10 commits on my local trunk since the last commit with a Svn ID. Hopefully that answers a few questions. Thanks again.

• What should a hobbyist do to develop good programming skills after basics?

  - by thyrgle

  So I'll say right here that I'm no professional coder. I'm a hobbyist. And pretty much like other people I feel like I'm doing it wrong. Like this question A feeling that I'm not a good programmer if have began to feel like that. Now I know basically that they say you shouldn't worry and that your good even if you continuously doubt yourself. But, they are talking to him. I'm not like him (in the sense I'm more of a newbie)... I've been coding as a hobbyist for 3 years (3 hobbyist years mind you!) unlike his 10-11 years that he states. Also, the only thing I've probably read in-depth is Teach Yourself C++ in 21 Days. And before I continue, just so your not confused about the various questions I've posted on (mostly) iPhone and OpenGL, I have poked and prodded at those two things for a few months each and finally sort of got a hang of both of them. But, from what I've noticed, is that I suck at making good code. For me its not even a debate of whether I'm doing it wrong or not: I can tell (from the various spaghetti code I create and other various discrepancies I, and others, can see and have noted in my code). What is a good way to get rid of these awful habits of mine and do it in a more correct, or if there is no "correct way" then I mean "typical", way?

• jQuery toggle div and text

  - by Jack

  I would like some help with this code, I have read similar questions & answers here on stackoverflow but I still can't get it right. I have a link that populated by .html("") to read more… when clicked it opens the hidden div and at the end the .html("") reads less. When I click close the div slides closed but the text still reads less… I have read many articles on how to do this but am confused and can't get past this last hurdle, any help would be much appreciated. // this is the intro div Ligula suspendisse nulla pretium, rhoncus tempor placerat fermentum, enim integer ad vestibulum volutpat. Nisl rhoncus turpis est, vel elit, congue wisi enim nunc ultricies sit, magna tincidunt. Maecenas aliquam maecenas ligula nostra, accumsan taciti. // this next div is hidden Ligula suspendisse nulla pretium, rhoncus tempor placerat fermentum, enim integer ad vestibulum volutpat. Nisl rhoncus turpis est, vel elit, congue wisi enim nunc ultricies sit, magna tincidunt. Maecenas aliquam maecenas ligula nostra, accumsan taciti. $(document).ready(function() { $(".overview-continued").hide(); $(".show-overview").html("more..."); $(".show-overview").click(function() { $(".overview-continued").slideToggle("1000"); $(".show-overview").html("less..."); return false; }); });
