  • Why '.png' files produced by ImageMagick are so much bigger than '.jpg' & '.gif' files?

    - by Nick Gorbikoff
    Hello. I'm using ImageMagick to convert some files from one format to another. I was always under the impression that .png files were supposed to be as big/small as .jpg if not smaller, and definitely smaller than .gif. However when I run convert photo.jpg photo.png The files I'm getting out is about 6 times bigger than the original jpg. Original jpg is a regular photo about 300x500 px, 52 kb. Output is a proper png of the same dimensions, but size is about 307 kb? Does anyoone know what the hack is going on? Am I doing something wrong? P.S.: I tried both on Debian and Windows with the same results.

  • Versioning system for MS Access

    - by Melissa L
    I am currently the only developer on a MS Access project, but we may soon be adding developers onto to the project. This will be my first time sharing the load on a single MS Access project and I'm a bit clueless as to what versioning system (ex. SubVersion) might work best. Any suggestions on programs I should be taking a look at or staying away from? Thanks for your help!

  • Hosted SVN - RepositoryHosting.com

    - by SVN User
    I'm currently reviewing repositoryhosting.com for possibly hosting our company code, however, I'm weary about pushing forward for a few reasons. First, if the company goes under, I have no assurance that I will have access to grab backups of the code prior. Secondly, their terms state this: "User agrees that Repository Hosting shall not be liable for any direct, indirect, incidental, special, consequential or exemplary damages, including but not limited to, damages for loss of profits, goodwill, use, data or other intangible losses resulting from the use of or inability to use the Service." Basically, I want to ensure that our data is safe. I understand that they do offsite backups and such, however, if there were to be a catastrophic loss of data that was their fault, would we be left with just a "sorry"? What about your thoughts on hosted svn and is it better to just continue to do it yourself?

  • Why is "origin/HEAD" shown when running "git branch -r"?

    - by Ben Hamill
    When you run git branch -r why the blazes does it list origin/HEAD? For example, there's a remote repo on GitHub, say, with two branches: master and awesome-feature. If I do git clone to grab it and then go into my new directory and list the branches, I see this: $ git branch -r origin/HEAD origin/master origin/awesome-feature Or whatever order it would be in (alpha? I'm faking this example to keep the identity of an innocent repo secret). So what's the HEAD business? Is it what the last person to push had their HEAD pointed at when they pushed? Won't that always be whatever it was they pushed? HEADs move around... why do I care what someone's HEAD pointed at on another machine? I'm just getting a handle on remote tracking and such, so this is one lingering confusion. Thanks! EDIT: I was under the impression that dedicated remote repos (like GitHub where no one will ssh in and work on that code, but only pull or push, etc) didn't and shouldn't have a HEAD because there was, basically, no working copy. Not so?

  • generate images with labels from a database

    - by Duncan Benoit
    hi there I need to have some images into my database, and the thing is that i need that images to have certain file names, dimensions and text on it. I know how to generate some images using the opencv lib, but this means that i need to install the lib and do just that job(which sounds as reinventing the wheel). Do you think is worth to do that or maybe you have a better idea? ps: the images are for testing stage of a software application, so i don;t need anything fancy or artistic.

  • Working with images in Scala

    - by dbyrne
    I am generating large PNG files from a Scala program. Currently, I am doing it the same way I would do it in java. I am creating a new BufferedImage and setting each pixel to the correct color. This works fine, but I am wondering if there are any good libraries for working with images in Scala? I am looking for something like Ruby's RMagick library.

  • Good Git repository viewer for Mac

    - by Sergio Acosta
    Can anyone recommend a good repository viewer for Git, similar to gitk, that works on Mac OS X Leopard? (I'm not saying gitk doesn't work) Of course I would like a native Mac application, but as I haven't found any, what are the best options to gitk? I know about gitview, but I'm looking forward to evaluate as many alternatives as possible. http://sourceforge.net/projects/gitview

  • PHP elseif statement not executed even though initial if statement is false

    - by DarwinIcesurfer
    I am writing a recursive function to print out the differences between 2 multildimensional php arrays. The purpose of this code is to see the difference between jpeg headers to deteremine how adobe bridge cs3 is saving rating information within the jpg file. When I am single-stepping through the code using my eclipse - zend debugger ide, it appears that even though the initial if statement is false (ie both values are arrays), the subsequent elseif statements are never executed. The function is attached below. function array_diff_multi($array1,$array2,$level){ $keys = array_keys($array1); foreach($keys as $key) { $value1 = $array1[$key]; if(array_key_exists($key,$array2) ){ $value2 = $array2[$key]; // Check if they are both arrays, if so recursion is needed if (is_array($value1) && is_array($value2)){ array_diff_multi($value1,$value2,$level . "[ " . $key . " ]"); } // the values aren't both arrays *** THE CODE IN THE ELSEIF BELOW IS NOT EXECUTED *** elseif(is_array($value1) != is_array($value2)){ print "" . $level . $key ."=" . $value1 . "as array, compared to ". $value2 .""; } // the values don't match elseif($value1 != $value2){ print "" . $level . $key ."=" . $value1 ." != " . $value2 .""; } else; } else{ print "" . $level. $key . "does not exist in array2"; } } }

  • Best way to order menu items injected by an IoC/plugin Framework

    - by Daver
    One of the common things I've seen done in applications built on IoC/plugin frameworks is to add commands to menus or toolbars from the dynamically loaded plugins. For example, the application's default plugins supply actions like "New, Open, Save" that show up in the context menu for a certain item in the workspace. A new plugin may add "Mail, Post, Encrypt" commands, but where do those commands show up in relation to "New, Open, Save"? How can the application that is loading components through IoC impose order on the items that get injected? Does it require metadata from the plugins that give a hint on how to group or order the items? Does it use a config file of previously known menu names (or ids) to define the order (seems a little weak to me)? Or are "unknown" plugins treated as second class citizens and always get dumped into sub menus? Something I've never even imagined (which I'm hoping to see in the answers)

  • Can you do conventions-based binding with StructureMap 2.5.3?

    - by Peter Goras
    I find one of the best features of Ninject is conventions-based binding. eg. Bind<IConfigurationSource>().To<RemoteConfigurationSource>() .Only(When.Context.Target.Name.BeginsWith("remote")); Bind<IConfigurationSource>().To<LocalConfigurationSource>() .Only(When.Context.Target.Name.BeginsWith("local")); http://ninject.codeplex.com/Wiki/View.aspx?title=Conventions-Based%20Binding&referringTitle=Home Is this possible in StructureMap 2.5.3? Thanks

  • .Net LoginControls - User can't logout in Firefox

    - by Jordan Foreman
    Basically, the logout link doesn't do anything, but only in Firefox. (I can login and out freely from other browsers) There really isn't a whole lot of information I can really give other than that, since I'm still new to this project and .net as a whole, and know almost nothing about the login controls. So if someone else has experienced a similar issue in the past, and can recognize the issue with the little info I have, that would be great! If not, sorry for the lack of depth, but its all I have. If it helps, here is the code for where the logout link is: <LoggedInTemplate> ... <asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log Out" LogoutPageUrl="~/Anonymous/Login.aspx" /> </LoggedInTemplate>

  • Subversion: Write protection for tagged directories

    - by Alexander
    Hi, i am using subversion as RCS. Always when a new version of my project is finised i create a tag of it (copy of the trunk). Does anybody know how i can protect this tagged directory from being accidentally modified? At the moment as a workaround i lock all files. But this sill means that the user with the lock can edit the files. Is there any better solution?

  • Is it possible to link directories in git?

    - by Andreas Selenwall
    I will start with a simplified example describing my intent. I have a repository my-rep.git containing two directories, src and deploy. In src I have my source code (NodeJS code, but that doesn't matter), and in deploy I want to keep my deploy configuration. So for example if I have a project, projectA, then the structure should look like this, my-rep.git/src/projectA my-rep.git/deploy/projectA/dotcloud.yml my-rep.git/deploy/projectA/src Now to my question. I want the source code in projectA to be available in the deploy directory for dotcloud. Is there any way I can make my-rep.git/deploy/projectA/src point to my-rep.git/src/projectA, that is, so when I do a git pull in deploy it will automatically pull the my-rep.git/deploy/projectA/src. It must be supported in git, symbolic linux links won't work as some developers in my team work in Windows.

    I have an ASP.NET web application for data entry, and we have big lists of radiobuttons, and long lists of checkboxes, in some sections. The client wants to be able to be able to navigate and manipulate these controls with their keyboard, like the tab/space/enter/right-left-up-down-arrow-keys. Are there any ASP.NET controls that I can use?

  • Browser application & local file system access

    - by Beyond HTML
    I want to enhance my browser-based web application with functionality that enables management of local files and folders. E.g. folder tree structures should be synchronized between local workstation and server via HTTP(S). I am aware of security-related limitations in browser-based applications. However, there are some techniques that "work around" these issues: Signed Java applets (full trust) .NET Windows Forms browser controls (no joke, that works. Just the configuration is horrible) ActiveX My question is: What do you use/suggest, both technology and implementation practice? Key requirement is that the installation process is as simple as possible. Thanks for your opinions!

  • svn says conflicted but it's really merged (TortoiseSVN)

    - by JoelFan
    Lately I've been seeing behavior where after an update svn shows certain files as "conflicted" but when I try to edit the conflicts, there are none (The "next conflict" and "previous conflict" buttons are disabled and if I scroll through the file, none of the lines are marked red). This seems to have started after I started working from a different repository than I had been working with, but I'm not sure if that's related.

  • IOC/Autofac problem

    - by Krazzy
    I am currently using Autofac, but am open to commentary regarding other IOC containers as well. I would prefer a solution using Autofac if possible. I am also somewhat new to IOC so I may be grossly misunderstanding what I should be using an IOC container for. Basically, the situation is as follows: I have a topmost IOC container for my app. I have a tree of child containers/scopes where I would like the same "service" (IWhatever) to resolve differently depending on which level in the tree it is resolved. Furthermore if a service is not registered at some level in the tree I would like the tree to be transversed upward until a suitable implementation is found. Furthermore, when constructing a given component, it is quite possible that I will need access to the parent container/scope. In many cases the component that I'm registering will have a dependency on the same or a different service in a parent scope. Is there any way to express this dependency with Autofac? Something like: builder.Register(c=> { var parentComponent = ?.Resolve<ISomeService>(); var childComponent = new ConcreteService(parentComponent, args...); return childComponent; }).As<ISomeService>(); I can't get anything similar to the above pseudocode to work for serveral reasons: A) It seems that all levels in the scope tree share a common set of registrations. I can't seem to find a way to make a given registration confined a certain "scope". B) I can't seem to find a way to get a hold of the parent scope of a given scope. I CAN resolve ILifetimeScope in the container and then case it to a concrete LifetimeScope instance which provides its parent scope, but I'm guessing it is probably note meant to be used this way. Is this safe? C) I'm not sure how to tell Autofac which container owns the resolved object. For many components I would like component to be "owned" by the scope in which it is constructed. Could tagged contexts help me here? Would I have to tag every level of the tree with a unique tag? This would be difficult because the tree depth is determined at runtime. Sorry for the extremely lengthy question. In summary: 1) Is there any way to do what I want to do using Autofac? 2) Is there another container more suited to this kind of dependency structure? 3) Is IOC the wrong tool for this altogether?
