  • Switch encoding of terminal with a command

    - by Tomas Lycken
    One of the servers I quite often ssh to uses western encoding instead of utf-8 (and there's no way I can change that). I've started writing a bash script to connect to this server, so I won't have to type out the entire address every time, but I would like to improve this script so it also changes the encoding of the terminal window correctly. The change I need to do can be performed using the mouse by navigating to "Terminal"-"Set Character Encoding..."-"Western (ISO-8859-1)". Is there a terminal command that does the same thing, for the current terminal window/screen? To clarify: I'm not interested in ways of switching the locale of the system on the remote site - that system is administered by someone else, and I have no idea what stuff might depend on the latin-1 encoding there. What I want to do is to let this terminal window on my side switch character encoding to the above mentioned, in the same way I can do with my mouse and the menus.

  • Using WebStorm for Razor Syntax MVC

    - by Jay Stevens
    I am building a lot of client-side heavy SPA-like apps with VS2010 and MVC3/4. VS2010 Javascript/HTML/CSS editing (mostly javascript) is interminably slow and sluggish. I'd love to use something like JetBrains' WebStorm to edit my .CSHTML files (with embedded javascript, etc. because I am using RAzor to pop in URL names, etc.) WebStorm seems to have all of the things I want.. better language recognition ("intellisense") and the ability to integrate additional outside libraries into this (I'm using Kendo), etc. Is this possible? How do you get WebStorm to recognize the @"" invoked Razor language inserts? Any help or suggestions would be appreciated.

  • Nautilus is really slow

    - by david
    Nautilus used to be lightning fast.Now it's dead slow. I have tried upgrading the video card but that does not seem to be the problem. Also I found that there was a problem with the Dropbox uninstall, finally I replace it with pcmanfm which appears to be much faster but the down side is that I no longer have the gwibber social client and a lot of stuff don't work like they use to. Also I completely removed nautilus and couldn't even login to ubuntu to install again nautilus.How can I remove or repair nautilus, and use pcmanfm instead? I have a dell inspiron 1440 3gb ram / disk 300gb / Additionally, why does nautilus run fast when I run it as root? There are no USB devices attached to my computer. Thanks in advance

  • Box2D Platform body not moving player body along with it

    - by onedayitwillmake
    I am creating a game using Box2D (Javascript implementation) - and I added the ability to have a static platform, that is moved along an axis as a function of a sine. My problem is when the player lands on the platform, as the platform moves along the X axis - the player is not moved along with it, as you visually would expect. The player can land on the object, and if it hits the side of the object, it does colide with it and is pushed. This image might explain better than I did: After jumping on to the red platform the player character will fall off as the platform moves to the right UPDATE: Here is a live demo showing the problem: http://onedayitwillmake.com/ChuClone/slideexample.php

  • DI/IoC in Java for a .NET'er used to Castle.Windsor

    - by Ciddan
    Is there a Java DI container that works in a similar way to the most excellent Castle.Windsor container on the .NET side? The Java containers I've had a look at all seem to rely on annotations (Guice) within my services, which I don't dig all that much - I'd like to go POJO all the way if possible. Spring on the other hand can do without the annotations, but it requires a lot of XML. XML configuration != maintainability. One of the really nice things about Castle.Windsor is the wiring you're able to set up in code with Installers, auto wiring based on naming conventions and whatnot. Ideally the container should also support lifecycle management and configuration; i.e. registering components as transient, singleton, pooled etc. Another bonus would be support for interceptors. Any tips would be greatly appreciated.

  • Row Count Plus Transformation

    As the name suggests we have taken the current Row Count Transform that is provided by Microsoft in the Integration Services toolbox and we have recreated the functionality and extended upon it. There are two things about the current version that we thought could do with cleaning up Lack of a custom UI You have to type the variable name yourself In the Row Count Plus Transformation we solve these issues for you. Another thing we thought was missing is the ability to calculate the time taken between components in the pipeline. An example usage would be that you want to know how many rows flowed between Component A and Component B and how long it took. Again we have solved this issue. Credit must go to Erik Veerman of Solid Quality Learning for the idea behind noting the duration. We were looking at one of his packages and saw that he was doing something very similar but he was using a Script Component as a transformation. Our philosophy is that if you have to write or Copy and Paste the same piece of code more than once then you should be thinking about a custom component and here it is. The Row Count Plus Transformation populates variables with the values returned from; Counting the rows that have flowed through the path Returning the time in seconds between when it first saw a row come down this path and when it saw the final row. It is possible to leave both these boxes blank and the component will still work.   All input columns are passed through the transformation unaltered, you are not permitted to change or add to the inputs or outputs of this component. Optionally you can set the component to fire an event, which happens during the PostExecute phase of the execution. This can be useful to improve visibility of this information, such that it is captured in package logging, or can be used to drive workflow in the case of an error event. Properties Property Data Type Description OutputRowCountVariable String The name of the variable into which the amount of row read will be passed (Optional). OutputDurationVariable String The name of the variable into which the duration in seconds will be passed. (Optional). EventType RowCountPlusTransform.EventType The type of event to fire during post execute, included in which are the row count and duration values. RowCountPlusTransform.EventType Enumeration Name Value Description None 0 Do not fire any event. Information 1 Fire an Information event. Warning 2 Fire a Warning event. Error 3 Fire an Error event. Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. For 2005/2008 Only - Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Row Count Plus Transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations, and this component requires a minimum of SQL Server 2005 Service Pack 1. Downloads The Row Number Transformation is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed. Row Count Plus Transformation for SQL Server 2005 Row Count Plus Transformation for SQL Server 2008 Row Count Plus Transformation for SQL Server 2012 Version History SQL Server 2012 Version 3.0.0.6 - SQL Server 2012 release. Includes upgrade support for both 2005 and 2008 packages to 2012. (5 Jun 2012) SQL Server 2008 Version 2.0.0.5 - SQL Server 2008 release. (15 Oct 2008) SQL Server 2005 Version 1.1.0.43 - Bug fix for duration. For long running processes the duration second count may have been incorrect. (8 Sep 2006) Version 1.1.0.42 - SP1 Compatibility Testing. Added the ability to raise an event with the count and duration data for easier logging or workflow. (18 Jun 2006) Version 1.0.0.1 - SQL Server 2005 RTM. Made available as general public release. (20 Mar 2006) Screenshot Troubleshooting Make sure you have downloaded the version that matches your version of SQL Server. We offer separate downloads for SQL Server 2005, SQL Server 2008 and SQL Server 2012. If you get an error when you try and use the component along the lines of The component could not be added to the Data Flow task. Please verify that this component is properly installed.  ... The data flow object "Konesans ..." is not installed correctly on this computer, this usually indicates that the internal cache of SSIS components needs to be updated. This is held by the SSIS service, so you need restart the the SQL Server Integration Services service. You can do this from the Services applet in Control Panel or Administrative Tools in Windows. You can also restart the computer if you prefer. You may also need to restart any current instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages.

  • Configuring mouse buttons to switch between apps?

    - by Matt Gregory
    I just installed 14.04, so I'm using the default setup (Unity, I guess). I have these two extra mouse buttons on the side of my mouse. Is there any way to map these so they can switch between open apps? What would be perfect is if clicking on button 6 (or whatever it is) would cycle forward through apps, button 7 would go backwards, and holding one of the buttons would show the task list and let you click on the app you want. That's really what I want.

  • .NET - refactoring code

    - by w0051977
    I have inherited and now further develop a large application consisting of an ASP.NET application, VB6 and VB.NET application. The software was poorly written. I am trying to refactor the code as I go along. The changes I am making are not live (they are contained in a folder on my development machine). This is proving to be time consuming and I am doing this along side other work which is the prioritiy. My question is: is this a practical approach or is there a better methodology for refactoring code? I don't have any experience with version control software or source control software and I am wandering if this is what I am missing. I am a sole developer.

  • 2D Pixel/sprite game in unity? [on hold]

    - by acidzombie24
    Hi I'm an absolute newbie in unity. In the past I was told unity is terrible for 2d games so I look away after looking at it for a few days. I don't remember if this was right before unity4 came out or after. I hear unity is fairly good at 2d now. I tried googling for tutorials but I'm doing it wrong. I could not find a good tetris or tic tac toe tutorial. What assets/tutorials do I want for a 2D game? Side question is what tutorials are good if I want to make a fire emblem/advance wars type game (HUD heavy grid base game)

  • How can I cap cloud-costs?

    - by Joe Simpson
    I am looking into launching a cloud-based product for consumers where with a prepaid account they can start a server with a simple click and load up the software and access it remotely. The technical side of that I can manage, but I am worried about the costs escalating ridiculously high for both me and my customers Is there a way I can Limit how much each server can cost me before it will be deactivated See how much a server is currently costing me (so I can deduct it from their account) with it being extremely reliable as I don't want to have to have a giant bill in any possibility.

  • Nvidia problems. I think.

    - by Nate D.
    Let me start off by saying, I've been trying to run Ubuntu on my custom PC for about 2 years. From 10.04 to 12.04, this problem persists. When I try to boot Ubuntu from either a USB stick or a CD, I see the normal Ubuntu splash screen. It looks like it's working, orange dots are moving, but then the screen glitches and freezes. I'm assuming this happens because there are no drivers for my graphics card (Nvidia GeForce 8800, I think). My motherboard has no onboard graphics, nor does it have a VGA out. So, how can I get this working on my system? Can I somehow put the drivers along side the .img on the USB stick? I can boot from my Ubuntu USB stick on my MacBook. In case that helps anyone...

  • How to change the default editor of a specific file type in JDeveloper

    - by [email protected]
    When you open a file in JDeveloper, the mode that is used as the default might not be what you as a developer want.  If, for example, every time you open a .jsp(x) file you click on the source tab at the bottom of the window so that you can edit the jsp(x) file in source code mode, you may want to consider changing the default editor for that file type.  This is easy to do in the JDeveloper tool preferences and can be a time saver in the long run, since some editors can take a while to start up and if you don't need them often, this would just be lost time.  Here are the steps:  From the JDeveloper menu, select Tools->Preferences...Select "File Types" in the tree component on the left side of the preferences dialog.Click on the "Default Editors" tab.Scroll to the file type you want to change.In the details section at the bottom of the dialog, use the "Default Editor" select list to change the default to your liking.

  • Ubuntu 12.10 Unity and Gnome not showing correctly after log in

    - by Luis Rodriguez
    Hello Ubuntu community. Since last Saturday when I was about to log into my ubuntu session as always using Unity interface, I came across with something that never happened to me before. When I logged in, the screen only showed the Desktop wallpaper but neither the bar from the top screen neither the dash bar from the left side appear, and after a few minutes of being logged in, I found myself being spammed with Ubuntu errors windows, over and over again. I logged out using ctrl+alt+del and tried my Gnome sessio. But I got exactly the same problem. I'm only able to use Gnome Classic and Classic (No Effects) Can anybody help? Hope a reply soon, and thanks in advance.

  • How can I remove the Unity Launcher?

    - by Magnus Hoff
    I'm running Ubuntu Netbook. With the recent upgrade to 10.10 I was excited about the Application Menu/the global menu bar and its implications for screen real estate. Unfortunately, the Unity Launcher on the left hand side of the screen takes more valuable space away than the new menu bar gives. Is there any way to get rid of the Launcher? Alternatives I would be satisfied with include: Not having the Launcher at all Having the Launcher hide automatically Having applications open on top of the Launcher (not next to it) (edit:) Note that I am specifically looking for a way to keep the global menubar, while getting rid of the Launcher.

  • Convert filenames to their checksum before saving to prevent duplicates. Is is a smart thing to do?

    - by Xananax
    TL;DR:what the title says I am developing some sort of image board in PHP. I was thinking of changing each image's filename to it's checksum prior to saving it. This way, I might be able to prevent duplicates. I know this wouldn't work for two images that are the same but differ in size or level of compression or whatnot, but this method would allow for an early check. What bugs me is that I never saw this method implemented anywhere, so I was wondering if there is a catch to it. Maybe it is just more efficient to keep the original filename and store the hash in DB? Maybe the whole method is just not useful and my question is moot? What do you think? On a side note, I don't really get how hashes are calculated so I was wondering, if my first question checks out, if it would be possible to calculate the likeness that two images are similar by comparing hashes (levenshtein or something of the sort).

  • What is the best approach to copy public dynamic pages?

    - by Renan
    Situation: the government is supposed to publish official information online such as acts and laws. Problem: they're using 90s expertise to do it. You can tell that by the constant use of deprecated html tags such as <table and the lack of any compression at all, which makes some documents go way over 700,000 bytes even though they're pure text. Side problem: some companies are actually editing and selling this content that should be public and free. What I need to know is the best approach to offer said official content in my own site for free. I've thought of setting up a mirror to copy the official pages from time to time, since some of them are updated frequently, which would automatically be compressed as all my pages are via htaccess.

  • What to choose API based server or Socket based server for data driven application

    - by Imdad
    I am working on a project which has a Desktop Application for MAC/COCOA, a native application for iPhone another native application in iPad. All the application do almost same thing. The applications are data driven applications. Every communication to server is made via a restful API developed in PHP. When a user logs in a lot of data is fetched from server. And to remain in sync with server pooling is done. As there are lot of data to pool it makes application slower and un-reliable. A possible solution that comes into my mind is to use Socket based server. My question is that will it reasonably improve the performance? And which technology (of sockets) will be good as a server side solution for data driven application? I have heard a lot about Node.js. Please give your suggestions.

  • Customizing UPK outputs (Part 2 - Player)

    - by [email protected]
    There are a few things that can be done to give the Player output a personalized look to match your corporate branding. In my previous post, I talked about changing the logo. In addition to the logo, you can change the graphic in the heading, button colors, border colors and many other items. Prior to making any customizations, I strongly recommend making a copy of the existing Player style. This will give you a backup in case things go wrong. I'd also recommend that you create your own brand. This way, when you install the newest updates from us, your brand will remain intact. Creating your own brand is pretty easy. Make sure you have modify permissions on the publishing styles directory, if you are using a multi-user installation. Under the Publishing/Styles folder, create a new folder with your company name. Copy all the publishing styles from the UPK folder to your newly created folder. Now, when you go through the Publishing wizard, you will have two categories to choose from: the UPK category or your custom category. Now, for updating the Player output. First, the graphic that appears on the right hand side of the Player. If you're using a multi-user installation, check out the player style from your custom brand. Open the player style. Open the img folder. The file named "banner_image.png" represents the graphic that appears on the right hand side of the player. It is currently sized at 425 x 54. Try to keep your graphic about the same size. Rename your graphic file to be "banner_image.png", and drag it into the img folder. Save the package. Check in the package if you are in a multi-user installation. You've just updated the banner heading! Next, let's work on updating some of the other colors in the player. All the customizable areas are located in the skin.css file which is in the root of the Player style. Many of our customers update the colors to match their own theme. You don't have to be a programmer to make these changes, honest. :) To change the colors in the player: Make a copy of the original skin.css file. (This is to make sure you have a working version to revert to, in case something goes wrong.) Open the skin.css file from the Player package. You can edit it using Notepad. Make the desired changes. Save the file. Save the package. Publish to view your new changes. When you open the skin.css, you will see groupings like this: .headerDivbar { height: 21px; background-color: #CDE2FD; } Change the value of the background-color to the color of your choice. Note that you cannot use "red" as a color, but rather you should enter the hexadecimal color code. If you don't know the color code, search the web for "hexadecimal colors" and you'll find many sites to provide the information. Here are a few of the variables that you can update. Heading: .headerDivbar -this changes the color of the banner that appears under the graphic Button colors: .navCellOn - changes the color of the mode buttons when your mouse is hovering on them. .navCellOff - changes the color of the mode buttons when the mouse is not over them Lines: .thorizontal - this is the color of the horizontal lines surrounding the outline .tvertical - this is the color of the vertical lines on the left and right margin in the outline. .tsep - this is the color of the line that separates the outline from the content area Search frame: .tocSearchColor - this is the color of the search area .tocFrameText - this is the background color of the TOC tree. Hint: If you want to try out the changes prior to updating the style, you can update the skin.css in some content you've already published for the player (it's located in the css folder of the player package). This way, you can immediately see the changes without going through publishing. Once you're happy with the changes, update the skin.css in player style. Want to customize more? Refer to the "Customizing the Player" section of the Content Development manual for more details on all the options in the skin.css that can be changed, and pictures of what each variable controls. I'd love to see how you've customized the player for your corporate needs. Also, if there are other areas of the player you'd like to modify but have not been able to, let us know. Feel free to share your thoughts in the comments. --Maria Cozzolino, Manager of Requirements & UI Design for UPK

  • Compute if a function is pure

    - by Oni
    As per Wikipedia: In computer programming, a function may be described as pure if both these statements about the function hold: The function always evaluates the same result value given the same argument value(s). The function result value cannot depend on any hidden information or state that may change as program execution proceeds or between different executions of the program, nor can it depend on any external input from I/O devices. Evaluation of the result does not cause any semantically observable side effect or output, such as mutation of mutable objects or output to I/O devices. I am wondering if it is possible to write a function that compute if a function is pure or not. Example code in Javascript: function sum(a,b) { return a+b; } function say(x){ console.log(x); } isPure(sum) // True isPure(say) // False

  • How can I best study a problem to determine whether recursion can/should be used?

    - by user10326
    In some cases, I fail to see that a problem could be solved by the divide and conquer method. To give a specific example, when studying the find max sub-array problem, my first approach is to brute force it by using a double loop to find the max subarray. When I saw the solution using the divide and conquer approach which is recursion-based, I understood it but ok. From my side, though, when I first read the problem statement, I did not think that recursion is applicable. When studying a problem, is there any technique or trick to see that a recursion based (i.e. divide and conquer) approach can be used or not?

  • css equivalent of table-row [closed]

    - by SpashHit
    I am trying to shift my style away from using tables to control formatting, but I haven't seen a simple css solution that does exactly the same thing as <table><tr><td>aribitrary-html-A</td><td>aribitrary-html-A</td></tr><table> All I want is to make sure aribitrary-html-A and aribitrary-html-B are aligned horizontally. I have tried various CSS concoctions using display: inline, clear: none, and float: left but they all have unwanted side-effects of moving my content around, while the table-tr solution just does what I want, regardless of what's in the arbitrary HTML, and regardless of what is in HTML that contains my table. Am I missing something?

  • Is it a good idea to create shared UI library that would render natively on different platforms?

    - by Maciej Donajski
    I am designing an application that has following flow: User designs a form using web application (J2EE backend application) The form is sent to mobile device (Android) Mobile device User fills out the form designed in 1. Results are synced with backend. One of my ideas is to create a common java UI library for creating the type of forms that I need. This library would also have a native renderers for different platforms (Web and Android would be implemented first). The whole point of it is to have a native experience on web and android side. Are there any existing solutions to meet the requirements that I have? Is it a good approach to achieve them?
