  • In git, how can I get the diff between two dates?

    - by Weidenrinde
    Basically, I am looking for something equivalent to cvs diff -D"1 day ago" -D"2010-02-29 11:11". While collecting more and more information, I found a solution. I paste it here, for others that might have similar problems. Things I have tried: In git, how can I get the diff between all the commits that occured between two dates? was ansered here with: git whatchanged --since="1 day ago" -p But this gives a diff for each commit, even if there are multiple commits in one file. I know that "date" is a bit of a loose concept in git, I thought there must be some way to do this. git diff 'master@{1 day ago}..master gives some warning warning: Log for 'master' only goes back to Tue, 16 Mar 2010 14:17:32 +0100. and does not show old diffs. git format-patch --since=yesterday --stdout does not give anything. revs=$(git log --pretty="format:%H" --since="1 day ago");git diff $(echo "$revs"|tail -n1) $(echo "$revs"|head -n1) works somehow, but seems complicated and does not restrict to the current branch. git diff $(git rev-list -n1 --before="1 day ago" master) seems to work and a default way to do similar things, although more complicated than I thought. Funnily, git-cvsserver does not support "cvs diff -D" (without that it is documented somewhere).

  • Defining Light Coordinates

    - by Zachary
    I took a Computer Graphics exam a couple of days ago which had extra credit question like the following: A light can be defined in one of two ways. It can be defined in world coordinates, e.g. a street light, or in the viewer (eye coordinates), e.g., a head-lamp worn by a miner. In either case the viewpoint can freely change. Describe how the light should be transformed different in these two cases. Since I won't get to see the results of this until after spring break, I thought I would ask here. It seems like the analogies being used are misleading - could you not define a light source that is located at the viewers eye in world coordinates just as well as you could in eye coordinates? I've been doing some research on how OpenGL handles light, and it seems as though it always uses eye coordinates - the ModelView matrix would be applied to any light in world coordinates. In that case the answer may just be that you would have to transform light defined in world coordinates into eye coordinates using something like the ModelView matrix, while light defined in eye coordinates would only need to be transformed by the projection matrix. Then again I could be totally under thinking (or over thinking this). Another thought I had is that it determines which way you render shadows, but that has more to do with the location of the light and its type (point, directional, emission, etc) than what coordinates it is represented in. Any ideas?

  • Raphael JS image animation performance.

    - by michael
    Hi, I'm trying to create an image animation using Raphael JS. I want the effect of a bee moving randomly across the page, I've got a working example but it's a bit "jittery", and I'm getting this warning in the console: "Resource interpreted as image but transferred with MIME type text/html" I'm not sure if the warning is causing the "jittery" movement or its just the way I approached it using maths. If anyone has a better way to create the effect, or improvements please let me know. I have a demo online here and heres my javascript code: function random(min, max) { return Math.floor(Math.random() * (max - min + 1)) + min; } function BEE(x, y, scale) { this.x = x; this.y = y; this.s = scale; this.paper = Raphael("head", 915, 250); this.draw = function() { this.paper.clear(); this.paper.image("bee.png", this.x, this.y, 159*this.s, 217*this.s); } this.update = function() { var deg = random(-25, 25); var newX = Math.cos(Raphael.rad(deg)) * 2; var newY = Math.sin(Raphael.rad(deg)) * 2; this.x += newX; this.y += newY; if( this.x > 915) { this.x = 0; } if( this.y > 250 || this.y < 0 ) { this.y = 125; } } } $(document).ready(function() { var bee = new BEE(100, 150, 0.4); var timer = setInterval(function(){ bee.draw(); bee.update(); }, 15); }

  • Passing an NSDate

    - by Garry
    I'm new to the iPhone and objective-c and I am still trying to get my head around ownership of objects so bear with me. I have a DOBViewController that has a datepicker on it. I have created a custom init method: -(id)initWithInitialDate(NSDate *)initialDate; Another view controller has a date instance declared (NSDate *dob) that holds a value. I would like to pass this to the DOBViewController so that it can scroll the datepicker to the passed value. Here is the custom init method: - (id)initWithInitialDate:(NSDate *)initialDate { // Initialise ourselves self = [super init]; // Set the date of the date picker if (initialDate != nil) { datePicker.date = initialDate; } else { // Set it to today datePicker.date = [NSDate date]; } return self; } This is how I am sending the dob NSDate object: DOBViewController *dobViewController = [[DOBViewController alloc] initWithInitialDate:dob]; Where dob is a variable of type NSDate that is declared in the header file. This doesn't seem to work as initialDate is always NULL. What am I doing wrong?

  • FileNotFoundException, although the XML file should be deployed

    - by Bernhard V
    Hi, I've got problems starting my WAR application on a local JBoss. After two other EARs are deployed and the TomcatDeployer begins deploying the WAR, I'm getting the following error message: 2010-04-28 10:01:56,605 ERROR [org.jboss.ejb.plugins.LogInterceptor] [] [main] EJBException in method: public abstract at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenRemote at.sozvers.stp.zpv.ejb.lea.rwsuc.EJBLeaRegelwerkSuchenHome.create() throws javax.ejb.CreateException,java.rmi.RemoteException, causedBy: javax.ejb.EJBException: org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition.

And at least I get a message that the deployment of the EAR has been successful. I also looked into the JAR with my file archiver and the ContextBasic.xml is indeed there at the right place. Is there a way for me to get sure that the JAR, not the EAR as a whole, is really deployed to the JBoss? I'm already starting to lose my head about this issue. Thank you. Bernhard

  • Embedded Vimeo Video Callbacks

    - by Andrew
    This post is kind of a follow up to a post I made earlier in regards to HTML5 video callbacks. In that thread, I was given a great piece of code that would allow for the browser to be informed of when the video stops playing and then fire off an action (with jQuery). This is the code I'm currently using: $('video.normal').bind('ended', function(){ $(this).fadeOut().queue(function(){ $(this).siblings('.post-video').fadeIn(); $(this).dequeue(); }); }); Which basically fades the video out when it's completed and brings a poster frame of the video (or similar image) back into view. Well, the scope of the project has changed and now the client is asking for true full screen video and different size videos to be delivered based on user connection speed, something that's a little over my head and a lot over budget. So I've been researching and a Vimeo Plus player seems like a great alternative for visitors using a desktop browser (HD embeds, true full screen, and more). Thing is, I need that above code to continue working in some capacity or another, so does the embedded Vimeo player offer a similar callback that I can utilize? Or am I SOL here? Thanks in advance!

  • embedded php in html to include header (top part of page) into the page

    - by Andy
    Hi there, I'm trying to put the top of my page (which is all html) in a seperate file so I only need to change things once like the menu bar etc. So I googled some and found a solution on this website as well, but it doesn't work and I don't know why. So I have a page like article.html and on the top I have this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head> <?php include("/pages/header.php"); ?> <!-- rest of the html code --> In the header.php I have the html that should be on the top of each page and it starts with: <?php /** * @author name * website header */ ?> <!-- html code --> So what's wrong with this. When I open the page article.html and right click on it to view the source, I can see the php from above calling the header.php file. Thanks!

  • Mouse bugginess - SWFObject, Firefox 3 for Mac, and Flash

    - by justinbach
    I'm pulling my hair out over a problem I'm encountering on Firefox 3.5 & 3.6 on OS X. I'm using SWFobject to embed an AmMap of the US, which has rollover tooltips for various states. The rollovers are working fine in every other browser I've tested, but they're very buggy on FF for Mac--most of the time they don't show up at all, but if I persistently click a state that's supposed to have a hover event, I might catch a glimpse of the tooltip. Here's the code for the SWFObject embed (incidentally, this isn't being done in the document head due to templating reasons). The reason that the SWFObject initialization is wrapped in Jquery's document.ready handler is that the swf wasn't even appearing in FF 3.5.9 for mac until I added that in: $(document).ready(function() { var params = { quality: "high", scale: "noscale", allowscriptaccess: "always", allowfullscreen: "true", bgcolor: "#FFFFFF", base:"/<?php print LANG . "/locations/" ?>" }; var flashvars = { path: "", settings_file: "mapsettings", data_file:"mapdata" }; var attributes = { id: "flashmap", name: "flashmap" }; swfobject.embedSWF("/assets/flash/ammap.swf", "flashmap", "470", "300", "8", null, flashvars, params, attributes); }); Any feedback would be greatly appreciate...site goes live in 48 hours! Thanks!

  • Questions about the MVC architecture

    - by ah123
    I started coding a considerably complicated web application, and it became quite a mess. So I figured I'd try to organize it in a better way. MVC seemed appropriate. I've never used MVC before, and researching about it I'm trying to consolidate a better perception of it (and my questions obviously reflect what I think I've learned so far). My questions are slightly JavaScript oriented: What object should make "AJAX" requests? The Controller or the Model? (seperation -- should the Model just store/manipulate the data, should it not care/know where the data came from, or should it be the one fetching it?) Should the Model call View functions providing them with data as arguments or should the View query (reference) the Model within itself? (seperation principles in mind, "the View shouldn't care/know where it gets the data from" -- is that correct?) In general, should the View "know" of the Model's existance, and vice-versa? Is the Controller the only thing gluing them together or is that simply incorrect? (I really doubt that statement is generally correct) There's a good chance I'd want to port this into a desktop/mobile application, so I would like to seperate components in a way that will allow me to achieve that task, replacing the current source of the data, HTTP requests, with DB access, and replacing the View. Maybe every approach that I've asked about is still "valid" MVC and it's just up to me to choose. I understand that nothing is set in stone, I'm just trying to have a (better) general idea in my head.

  • Why can't I create a database in an empty ASP MVC 2 project using Project->Add->New Item->SQL Server

    - by Dr Dork
    I'm diving head first into ASP MVC and am playing around with creating and manipulating a database. I did a search and found this tutorial for creating a database, however when I follow it, I get this error when trying to add a new database to my fresh, empty ASP MVC 2 project... A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) The only requirement the tutorial mentioned was SQL Server Express, but when I went to download it, it said it was already installed. I'm assuming it was part of the VS 2010 RC I installed and am running. So I don't know what else I need if I am missing something. This is all new to me, so I'm sure I'm missing something obvious here and after I'm done posting this question, I plan to do some more research into the topic of databases and how they work with ASP MVC. In the meantime, I was you could help me answer a couple high level questions... What am I missing/forgetting to do that is causing this error? Any suggestions for good resources/tutorials that focus on using databases with ASP MVC? I've done a lot of database programming in the past, so I'm familiar with the concepts of relational databases and the SQL language. I wish I could find a good resource for learning how to work with them in an ASP dev environment, as well as a good breakdown of all the related technologies used for working with them (i.e. LINQ to SQL). Thanks so much in advance for all your help! I'm going to start researching these questions right now.

  • SQL Server Clustered Index: (Physical) Data Page Order

    - by scherand
    I am struggling understanding what a clustered index in SQL Server 2005 is. I read the MSDN article Clustered Index Structures (among other things) but I am still unsure if I understand it correctly. The (main) question is: what happens if I insert a row (with a "low" key) into a table with a clustered index? The above mentioned MSDN article states: The pages in the data chain and the rows in them are ordered on the value of the clustered index key. And Using Clustered Indexes for example states: For example, if a record is added to the table that is close to the beginning of the sequentially ordered list, any records in the table after that record will need to shift to allow the record to be inserted. Does this mean that if I insert a row with a very "low" key into a table that already contains a gazillion rows literally all rows are physically shifted on disk? I cannot believe that. This would take ages, no? Or is it rather (as I suspect) that there are two scenarios depending on how "full" the first data page is. A) If the page has enough free space to accommodate the record it is placed into the existing data page and data might be (physically) reordered within that page. B) If the page does not have enough free space for the record a new data page would be created (anywhere on the disk!) and "linked" to the front of the leaf level of the B-Tree? This would then mean the "physical order" of the data is restricted to the "page level" (i.e. within a data page) but not to the pages residing on consecutive blocks on the physical hard drive. The data pages are then just linked together in the correct order. Or formulated in an alternative way: if SQL Server needs to read the first N rows of a table that has a clustered index it can read data pages sequentially (following the links) but these pages are not (necessarily) block wise in sequence on disk (so the disk head has to move "randomly"). How close am I? :)

  • Advice on coding Perl to work like PHP

    - by user272273
    I am first and foremost a perl coder, but like many, also code in PHP for client work, especially web apps. I am finding that I am duplicating a lot of my projects in the two languages, but using different paradigms (e.g. for handling cgi input and session data) or functions. What I would like to do is start to code my Perl in a way which is structured more like PHP, so that I a) am keeping one paradigm in my head b) can more quickly port over scripts from one to the other Specifically, I am asking if people could advise how you might do the following in perl? 1) Reproduce the functionality of $_SESSION, $_GET etc. e.g. by wrapping up the param() method of CGI.pm, a session library? 2) Templating library that is similar to PHP I am used to mixing my code and HTML in the PHP convention. e.g. i <h1>HTML Code here</h1> <? print "Hello World\b"; ?> Can anybody advise on which perl templating engine (and possibly configuration) will allow me to code similarly? 3) PHP function library Anybody know of a library for perl which reproduces a lot of the php inbuilt functions?

  • Internet Explorer Warning when embedding Youtube on HTTPS site?

    - by pellepim
    Our application is run over HTTPS which rarely presents any problems for us. When it comes to youtube however, the fact that they do not present any content over SSL connections is giving us some head ache when trying to embed clips. Mostly because of Internet Explorers famous little warning message: "Do you want to view only the webpage content that was delivered securely? This page contains content that will not be delivered using a secure HTTPS ... etc" I've tried to solve this in several ways. The most promising one was to use the ProxyPass functionality in Apache to map to YouTube. Like this: ProxyPass: /youtube/ http://www.youtube.com ProxyPassReverse: /youtube/ http://www.youtube.com This gets rid of the annoying warning. However, the youtube SWF fails to start streaming The SWF i manage to load into the browser simply states : "An error occurred, please try again later". Potential solutions are perhaps: Download youtube FLV:s and serve them out of own domain (gah) Use custom FLV-player and stream only FLV:s from youtube over a https proxy? Update 10 March: I've tried to use Googles Youtube API for ActionScript to load a player. It looked promising at first and I was able to load a player through my https:// proxy. However, the SWF that is loaded contains loads of explicit calls to different non-ssl urls to create authentication links for the FLV-stream and for loading different crossdomain policies. It really seems like we're not supposed to access flv-streams directly. This makes it very hard to bypass the Internet Explorer warning, short of ripping out the FLV:s from youtube and serving them out of your own domain. There are solutions out there for downloading youtubes FLV:s. But that is not compliant with the Youtube terms of use and is really not an option for us.

  • How does one target all divs of any webpage but differentiate them in javascript?

    - by Chaz
    So I am trying to create an extension in Chrome (a prototype for a project that I am doing) that targets all of the <div> tags of any web page, hides them or rather doesn't display them until the user clicks the mouse (further explained below). So typing a url into the browser yields a white page. The person clicks, and the first <div> appears (probably the mast head or menu). The user clicks again and the second <div> appears. I have gotten to the point where I can hide or show all <div>'s (the obvious easy part) but I am not sure how to go about targeting each since every website has different id's for them while still using the <div> tag. This is what I need the most help with. This is part of a grander operation called the Web Crank. It's just a physical crank that controls the speed by which a web page loads. Each time you make one full rotation of the crank, one section (the first <div>) of the web page loads. The faster you go, the quicker the page loads. I hope this is clear enough. I am a newbie when it comes to this, but I have done some minor coding in the past and it's not such a big deal. Thanks for your help!

  • how to: dynamically load google ajax api into chrome extension content script

    - by Hoff
    Hi there, I'm trying to make use of google's ajax apis in a chorme extension's "content script". On a regular html page, I would just do this: <script src="http://www.google.com/jsapi"></script> <script> google.load("language", "1"); </script> But since I'm trying to load the tranlation library dynamically from js code, I've tried: script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.type = "text/javascript"; document.getElementsByTagName("head")[0].appendChild(script); google.load('language','1') but the last line throws the following error: Uncaught TypeError: Object # has no method 'load' Funny enough, when i enter the same "google.load('language','1')" in chrome's js console, it works as intended... I've also tried with jquery's .getScript() but the same problem persists... Does anybody have any clue what might be the problem and how it could be solved? Many thanks in advance! Martin

  • SQL Joining Two or More from Table B with Common Data in Table A

    - by Matthew Frederick
    The real-world situation is a series of events that each have two or more participants (like sports teams, though there can be more than two in an event), only one of which is the host of the event. There is an Event db table for each unique event and a Participant db table with unique participants. They are joined together using a Matchup table. They look like this: Event EventID (PK) (other event data like the date, etc.) Participant ParticipantID (PK) Name Matchup EventID (FK to Event table) ParicipantID (FK to Participant) Host (1 or 0, only 1 host = 1 per EventID) What I'd like to get as a result is something like this: EventID ParticipantID where host = 1 Participant.Name where host = 1 ParticipantID where host = 0 Participant.Name where host = 0 ParticipantID where host = 0 Participant.Name where host = 0 ... Where one event has 2 participants and another has 3 participants, for example, the third participant column data would be null or otherwise noticeable, something like (PID = ParticipantID): EventID PID-1(host) Name-1 (host) PID-2 Name-2 PID-3 Name-3 ------- ----------- ------------- ----- ------ ----- ------ 1 7 Lions 8 Tigers 12 Bears 2 11 Dogs 9 Cats NULL NULL I suspect the answer is reasonably straightforward but for some reason I'm not wrapping my head around it. Alternately it's very difficult. :) I'm using MYSQL 5 if that affects the available SQL.

    We have an IHttpHandler for stylesheets and add a <link/> tag to the page like this: HtmlGenericControl link = new HtmlGenericControl("link"); link.Attributes.Add("rel", "stylesheet"); link.Attributes.Add("href", "stylesheet.axd?d=" + HttpServerUtility.UrlTokenEncode(token)); head.Controls.Add(link); In the stylesheet.axd handler, we UrlTokenDecode the d query string parameter like this: var token = HttpServerUtility.UrlTokenDecode(Request.QueryString["d"]); This works most of the time but every now and then we find one of the following two exceptions in our log: [FormatException: Invalid character in a Base-64 string.] System.Convert.FromBase64CharArray(Char[] inArray, Int32 offset, Int32 length) System.Web.HttpServerUtility.UrlTokenDecode(String input) ... [FormatException: Invalid length for a Base-64 char array.] System.Convert.FromBase64CharArray(Char[] inArray, Int32 offset, Int32 length) System.Web.HttpServerUtility.UrlTokenDecode(String input) System.Web.HttpServerUtilityWrapper.UrlTokenDecode(String input) ... Any ideas what would cause this phenomenon? Remarks: the resulting URL is < 1500, so below any known URL limits (e.g. IE: 2083) seems to be independent of user agent (we have these exceptions for IE6,7,8, FF & Chrome) our (unconfirmed) suspicions include AntiVirus products, HTTP proxies, browser addons found this remotely related question, but it's about a viewstate issue

  • Subscription website architecture questions + SQL Server & .NET

    - by chopps
    Hey Guys, I have a few questions about the architecture of a subscription service I am about to embark on and I am looking for some feedback on how best to set it up. I won’t have a large amount of customers as Basecamp, maybe a few hundred and was wondering what would be a solid architecture for setting up the customer sites. I’m running SQL Server and .NET on a dedicated machine. Should create a new database for each customer as to have control and isolation of data or keep them all in one database? I am also thinking of creating a sub-domain for each customer as well so modifications can be made to each site as needed. The customer URLs would look like this: https://customer1.foobar.com https://customer2.foobar.com I am going to have the ability to ‘plug-in’ reports that will be uploaded to the site so each customer can customize as needed. Off the top of my head this necessitates having each sub domain on its own code-base for the uploading of these reports. So on the main site the customer would sign up for their new subscription and I would programmatically create a new directory for the customer from the main code base and then create a sub domain pointing to the new directory for the customer and then finally their database. Does this sound about right? Am I on the right track? How do other such sites accomplish the same thing? Thanks for letting me bend your ear for a bit on this.

  • Manually Writing the HTML in TWebBrowser Pt. 2

    - by nomad311
    As the name suggests this is a continuation (sort of) of http://stackoverflow.com/questions/2784679/manually-writing-the-html-in-twebbrowser This time around I'm trying to add some auto-refresh logic to the HTML I get. I have pieced together an approach from several sources (see below). In short, I am trying to locate the title node and add a meta node after it (in the HTML head node). But, I get an access violation. Here is the source: iHtmlDoc := IHTMLDocument3(WebBrowser1.Document); iHtmlEleTitle := IHTMLElement2(iHtmlDoc.getElementsByName('title').item(0, 0)); iHtmlEle := IHTMLElement2(IHTMLDocument2(iHtmlDoc).createElement(Format('<meta http-equiv="refresh" content="%d">', [1]))); iHtmlEleTitle.insertAdjacentElement('afterEnd', IHTMLElement(iHtmlEle)); And A (technically not functionally) different way of doing it ...casting is slightly different here: IHTMLElement2(IHtmlDocument3(WebBrowser1.Document).getElementsByName('title').item(0, 0)).insertAdjacentElement('afterEnd', IHTMLDocument2(WebBrowser1.Document).createElement(Format('<meta http-equiv="refresh" content="%d">', [VPI_ISSUANCE_AUTO_RELOAD]))); Again all I get from Delphi is a access exception, and I fished through MSDN documentation on it, but now I'm hoping someone out there has gone through the same and has some insight. Any help?

  • Time complexity with bit cost

    - by Keyser
    I think I might have completely misunderstood bit cost analysis. I'm trying to wrap my head around the concept of studying an algorithm's time complexity with respect to bit cost (instead of unit cost) and it seems to be impossible to find anything on the subject. Is this considered to be so trivial that no one ever needs to have it explained to them? Well I do. (Also, there doesn't even seem to be anything on wikipedia which is very unusual). Here's what I have so far: The bit cost of multiplication and division of two numbers with n bits is O(n^2) (in general?) So, for example: int number = 2; for(int i = 0; i < n; i++ ){ number = i*i; } has a time complexity with respect to bit cost of O(n^3), because it does n multiplications (right?) But in a regular scenario we want the time complexity with respect to the input. So, how does that scenario work? The number of bits in i could be considered a constant. Which would make the time complexity the same as with unit cost except with a bigger constant (and both would be linear). Also, I'm guessing addition and subtraction can be done in constant time, O(1). Couldn't find any info on it but it seems reasonable since it's one assembler operation.

  • Perl to Ruby conversion (multidimensional arrays)

    - by Alex
    I'm just trying to get my head around a multidimensional array creation from a perl script i'm currently converting to Ruby, I have 0 experience in Perl, as in i opened my first Perl script this morning. Here is the original loop: my $tl = {}; for my $zoom ($zoommin..$zoommax) { my $txmin = lon2tilex($lonmin, $zoom); my $txmax = lon2tilex($lonmax, $zoom); # Note that y=0 is near lat=+85.0511 and y=max is near # lat=-85.0511, so lat2tiley is monotonically decreasing. my $tymin = lat2tiley($latmax, $zoom); my $tymax = lat2tiley($latmin, $zoom); my $ntx = $txmax - $txmin + 1; my $nty = $tymax - $tymin + 1; printf "Schedule %d (%d x %d) tiles for zoom level %d for download ...\n", $ntx*$nty, $ntx, $nty, $zoom unless $opt{quiet}; $tl->{$zoom} = []; for my $tx ($txmin..$txmax) { for my $ty ($tymin..$tymax) { push @{$tl->{$zoom}}, { xyz => [ $tx, $ty, $zoom ] }; } } } and what i have so far in Ruby: tl = [] for zoom in zoommin..zoommax txmin = cm.tiles.xtile(lonmin,zoom) txmax = cm.tiles.xtile(lonmax,zoom) tymin = cm.tiles.ytile(latmax,zoom) tymax = cm.tiles.ytile(latmin,zoom) ntx = txmax - txmin + 1 nty = tymax - tymin + 1 tl[zoom] = [] for tx in txmin..txmax for ty in tymin..tymax tl[zoom] << xyz = [tx,ty,zoom] puts tl end end end The part i'm unsure of is nested right at the root of the loops, push @{$tl->{$zoom}},{ xyz => [ $tx, $ty, $zoom ] }; I'm sure this will be very simple for a seasoned Perl programmer, thanks! `

  • [Asp.Net MVC] Encoding a character

    - by Trimack
    Hi, I am experiencing some weird encoding behaviour in my ASP.NET MVC project. In my Site.Master there is <div class="logo"> <a href="<%=Url.Action("Index", "Win7")%>"><%= Html.Encode("Windows 7 Tutoriál") %></a></div> which translates to the resulting page as <div class="logo"> <a href="/">Windows 7 TutoriA?l</a></div> However, in the Index.aspx there is <h1> Windows 7 Tutoriál</h1> which translates correctly on the same resulting page. I do have <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> as my first line in <head>. Locally, both files are saved in UTF-8 encoding. Any ideas why is this happening and how to fix it? Thanks in advance.

  • State Monad, why not a tuple?

    - by thr
    I've just wrapped my head around monads (at least I'd like to think I have) and more specifically the state monad, which some people that are way smarter then me figured out, so I'm probably way of with this question. Anyway, the state monad is usually implemented with a M<'a as something like this (F#): type State<'a, 'state> = State of ('state -> 'a * 'state) Now my question: Is there any reason why you couldn't use a tuple here? Other then the possible ambiguity between MonadA<'a, 'b> and MonadB<'a, 'b> which would both become the equivalent ('a * 'b) tuple. Edit: Added example for clarity type StateMonad() = member m.Return a = (fun s -> a, s) member m.Bind(x, f) = (fun s -> let a, s_ = x s in f a s_) let state = new StateMonad() let getState = (fun s -> s, s) let setState s = (fun _ -> (), s) let execute m s = m s |> fst

  • [mercurial] Prevent "hg status" from showing everything under untracked directories

    - by Wei Hu
    I find the output of hg status too verbose for untracked directories. Suppose I have an empty repository that's managed by both git and hg. So there would be two directories, .git and .hg. The output of git status is: # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .hg/ The output of hg status is: ? .git/HEAD ? .git/config ? .git/description ? .git/hooks/applypatch-msg.sample ? .git/hooks/commit-msg.sample ? .git/hooks/post-commit.sample ? .git/hooks/post-receive.sample ? .git/hooks/post-update.sample ? .git/hooks/pre-applypatch.sample ? .git/hooks/pre-commit.sample ? .git/hooks/pre-rebase.sample ? .git/hooks/prepare-commit-msg.sample ? .git/hooks/update.sample ? .git/info/exclude Is there a way to reduce its output to something like the following line? ? .git/
