• Do delegates defy OOP

  - by Dave Rook

  I'm trying to understand OOP so I can write better OOP code and one thing which keeps coming up is this concept of a delegate (using .NET). I could have an object, which is totally self contained (encapsulated); it knows nothing of the outside world... but then I attach a delegate to it. In my head, this is still quite well separated as the delegate only knows what to reference, but this by itself means it has to know about something else outside it's world! That a method exists within another class! Have I got myself it total muddle here, or is this a grey area, or is this actually down to interpretation (and if so, sorry as that will be off topic I'm sure). My question is, do delegates defy/muddy the OOP pattern?

• Where are the systray icons for Dropbox in Ubuntu desktop 13.04 (minimal)?

  - by samvv

  I reinstalled Ubuntu desktop using the minimal CD image and the following command: $ sudo apt-get install ubuntu-desktop --no-install-recommends After that I used Ubuntu Software Center to make sure Unity supports application indicators: http://i.imgur.com/bYF162w.png. Everything works great, except for Dropbox. For some reason the icon doesn't appear in the tray, even though the application is running. Steam on the other hand runs just fine, so it seems like there is nothing wrong with the tray itself. According to this post the tray icons should be in /usr/shared/icons/hicolor/22x22/status but it doesn't contain any Dropbox icons. Neither do any of the other resolutions. The answer is a bit outdated, so I'm not entirely sure it is still applicable to the current version of Dropbox. I did the usual thing of reinstalling dropbox with: sudo apt-get purge nautilus-dropbox sudo apt-get install nautilus-dropbox But that didn't solve anything either. Does somebody know how to fix this issue?

• Class as first-class object

  - by mrpyo

  Could a class be a first-class object? If yes, how would the implementation look? I mean, how could syntax for dynamically creating new classes look like? EDIT: I mean what example syntax could look like (I'm sorry, English is not my native language), but still I believe this question makes sense - how you give this functionality while keeping language consistent. For example how you create reference for new type. Do you make reference first-class object too and then use something like this: Reference<newType> r = new Reference<newType>(); r.set(value); Well this could get messy so you may just force user to use Object type references for dynamically created classes, but then you loose type-checking. I think creating concise syntax for this is interesting problem which solving could lead to better language design, maybe language which is metalanguage for itself (I wonder if this is possible).

• Can't get into the admin console after migrating to new server

  - by Emerson

  I migrated my WordPress blog to a new server, and everything seemed to be working fine until it started giving me the error when entering the admin area: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 4864 bytes) in /home/neworder/public_html/blog/wp-admin/includes/plugin.php on line 729 The line 729 has: $protected = array( '_wp_attached_file', '_wp_attachment_metadata', '_wp_old_slug', '_wp_page_template' ); I had installed the maintenance-mode, and I have suspicions that this is what broke the forum. If I remove the plugin it then gives another error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 19456 bytes) in /home/neworder/public_html/blog/wp-admin/includes/post.php on line 1158 And that line has: $content .= '<p class="hide-if-no-js">' . esc_html__( 'Remove featured image' ) . '</p>'; } I tried to restore the blog file-system from the old server and also to restore the database from the old server (2x), but still it gives me the same error. The blog itself seems to be working fine: http://blog.antinovaordemmundial.com/

• 3 Ways to Normalize Sound Volume on Your PC

  - by Chris Hoffman

  If you’re constantly adjusting your computer’s volume while you watch videos or play music, there’s a better way. You can set a consistent volume level, either Windows-wide or in a specific program like VLC or your music player. Many applications have “volume normalization” or “loudness equalization” features built-in, including Windows itself. These features are often somewhat hidden and off the beaten path, so you won’t find them unless you go looking for them.

• alt+shift can't be set to toggle language

  - by Ali

  I recently did a fresh installation of Ubuntu 13.10; but there is something bothering me, which I don't quite understand. When I first tried to toggle the keyboard language(I usually switch between Persian and English) using the good old "alt+shift" shortcut it didn't work. Then, I went and checked the Keyboard shortcut settings and found out that it had been set to "super+space"(which BTW didn't work either). So I tried to change it back to "alt+shift" but it just doesn't work; when I press "alt+shift" to set it up as the toggle-language shortcut, the box automatically resets itself to its previous value(without any errors whatsoever). As far as I've checked I couldn't find any thing obvious corresponding to the shortcut "alt+shift" either. I've currently set up the shortcut as "Ctrl+space"; so I can toggle the language. My question is why I cannot set it up to just "alt+shift"?

• Self-documenting code vs Javadocs?

  - by Andiaz

  Recently I've been working on refactoring parts of the code base I'm currently dealing with - not only to understand it better myself, but also to make it easier for others who are working on the code. I tend to lean on the side of thinking that self-documenting code is nice. I just think it's cleaner and if the code speaks for itself, well... That's great. On the other hand we have documentation such as javadocs. I like this as well, but there's a certain risk that comments here gets outdated (as well as comments in general of course). However, if they are up-to-date they can be extremely useful of say, understanding a complex algorithm. What are the best practices for this? Where do you draw the line between self-documenting code and javadocs?

• What's an easy way to remember what the term 'memoization' means

  - by Evan Plaice

  I know this sounds like a strange question. Intuitively, I know what the concept of memoization means because I have used it in my code before I ever heard of the term. The problem is, I use it so rarely that I lose the association and have to look it up; and, it feels like technobabble (read. gibberish) every time I use it. I might as well be a 'turboenacabulator'. Is there an easy/simple way to describe how memoization works that relates to the word itself.

• Consuming ASMX and WCF Services using jQuery

  - by bipinjoshi

  In the previous part I demonstrated how jQuery animations can add some jazz to your web forms. Now let's see one of the most important feature of jQuery that you will probably use in all data driven websites - accessing server data. In the previous articles you used jQuery methods such as $.get() to make a GET request to the server. More powerful feature, however, is to make AJAX calls to ASP.NET Web Services, Page Methods and WCF services. The $.ajax() method of jQuery allows you to access these services. In fact $.get() method you used earlier internally makes use of $.ajax() method but restricts itself only to GET requests. The $.ajax() method provides more control on how the services are called.http://www.bipinjoshi.net/articles/479571df-7786-4c50-8db6-a798f195471a.aspx

• Netbook partitioning scheme suggestions

  - by David B

  I got a new Asus EEE PC 1015PEM with 2GB RAM and a 250GB HD. After playing with the netbook edition a little, I would like to install the desktop edition I'm used to. In addition to ubunto partition(s), I would like to have one separate partition for data (documents, music, etc.), so I could try other OSs in the future without losing the data. What partition scheme would you recommend? I usually like to let the installation do it by itself, but when I try to that I can only use the entire disk, so I don't get the desired data partition. I wish there was a way to see the recommended default partitioning scheme, then just tweak it a bit to fit your needs (instead of building one from scratch). So, how would you recommend I partition my HD? Please be specific since I never manually partitioned before. Thanks!

• how to check that Google Analytics Tracking Code is firing on an iPad

  - by crmpicco

  I am used to using the Firebug extension "Omnibug" with Firefox to check that Google Analytics Tracking Code is firing on my website. This application works very well and has minimal overhead. I am now testing the website on an iPad and would like to know if there is a way to check that the GATC is firing on the iPad natively? I have spoofed the iPad UA string on Firefox on the desktop and it appears to fire correctly, however i'd like to see it happening on the device itself (if at all possible). I know that Firebug can be installed on an iPhone by means of a bookmarklet, however it is 1) quite buggy and not very user-friendly and 2) it doesn't support Omnibug. How can I check that my GATC is firing on my iPad?

• How can I have better sound quality?

  - by joelalmeidaptg

  I have been using Ubuntu for years now, and the latest Ubuntu 13.10 is working perfectly on my N56VZ. The image quality is awesome, better than on Windows, but there is one thing that is really bugging me and that kills my "cinema" experience... The sound. Ubuntu sound quality isn't nearly as good as it does on Windows using Realtek (with Powerful on the equalizer). On Ubuntu the sound is like "faded", it isn't as clear as on Windows. This happens on the system overall: VLC, Youtube, Rhythmbox... I think it is pulse itself that has a horrible sound quality. So, does anyone knows a solution for this? How can I have better sound quality on Ubuntu?

• MAAS fails to Commission nodes

  - by user3644848

  I'm evaluating MaaS/Juju. I followed instructions in this link http://maas.ubuntu.com/docs1.5/install.html to setup MaaS. I'm running this in Oracle VirtualBox environment so Power options are not configured for the VMs. PXE booting VM works fine. The node shuts down itself and registers with MaaS in Declared state. Issues: a) When I Commission the VM (which is in the Declared state), first it gets IP-Config: no response after 60 secs - giving up errors. (See link below for a screenshot). b) Fails to mount the boot device and drops into initramfs prompt. I've copied logs here: https://www.dropbox.com/sh/5gy9nnonbnccufo/AAD9o4awSOtyaCCmRe5q7rBva Any help to get past this is greatly appreciated. Thanks!

• Is there a way to group 2 or 3 gui windows so that they don't get lost behind other open windows?

  - by Gonzalo

  For instance floating panels and main window in Gimp are independent windows. If I change focus to a full window (e.g. Firefox by doing Alt-Shift) and go back to the main Gimp window I don't get back the floating panels also (I have to change to them as well in order to see them). It would be great if the 3 windows can be "tied" (or linked) together in order that they don't get lost behind other open windows when I change back to (make active window) any of them? I think this configuration (if it exists) should show itself more obviously in the gnome environment. This question seems to address the same problem but it doesn't seem to be accurately answered.

• .NET Compiler Platform (Roslyn) , its relevance to developer community and its performance? [on hold]

  - by jerriclynsjohn

  I'm just starting out with a Code-Quality-plugin development for my organization based on the recently released .NET Compiler Platform APIs (Roslyn APIs). I would like to know what are the most relevant possible ways that it could be used by the developer community apart from the usual IDE experience as answered in other questions. I was wondering the implications of opening up a compiler to general public and never came across anything "breakthrough", that could possibly add up to the value of IDE experiences. Is there any performance bottleneck for its implementation since the compiler itself is managed code?

• Transferring local site to shared hosting

  - by Pete

  I'm looking to setup a simple online text processing tool similar to the Clang demo. The processing program itself is a C++ program which I can modify to provide the desired output I need. Since I use Linux+Perl daily and have used Apache in the past, I'd like to get this working locally first. My two questions are: Is it possible to do this with only Apache and Perl? I've looked into frameworks for doing this and quickly ran into The Paradox Of Choice. Will I be able to easily transfer a working local site to a shared hosting service? I want to administer as little as possible. My understanding is since this needs to run a C++ program that CGI is a requirement and thus I need to administer the httpd server. Hopefully this doesn't mean a VPS. Thanks

• Collision detection in multiplayer games

  - by Bane

  This a followup to my previous question: How to implement physics and AoE spells in an MMO game?. There, we concluded that all physics have to be done on the server, and that I should use cylinders for calculations. Now, how can I check for collision detection on a ground-to-player basis on the server? It's fairly easy if the ground is a flat space, I just check if the player's z coordinate is lower than some value and voila, but, what if the map/ground itself is a model? How do I know where hills are on the server-side? How do I know when object collisions happen? I'm using node.js and socket.io.

• Pattern for performing game actions

  - by Arkiliknam

  Is there a generally accepted pattern for performing various actions within a game? A way a player can perform actions and also that an AI might perform actions, such as move, attack, self-destruct, etc. I currently have an abstract BaseAction which uses .NET generics to specify the different objects that get returned by the various actions. This is all implemented in a pattern similar to the Command, where each action is responsible for itself and does all that it needs. My reasoning for being abstract is so that I may have a single ActionHandler, and AI can just queue up different action implementing the baseAction. And the reason it is generic is so that the different actions can return result information relevant to the action (as different actions can have totally different outcomes in the game), along with some common beforeAction and afterAction implementations. So... is there a more accepted way of doing this, or does this sound alright?

• Inkscape won't open .cdr files

  Hello I'm running Kubuntu 12.04 and I've installed Inkscape because I need to edit a .cdr file, Inkscape works like normal but the sole task I need it to do is edit said .cdr file which I understand it should be capable off by default. Whenever I try to open the file though I get the following error: UniConvertor failed: The eror itself is longer but what it seems to be saying that it can't find this application, and I myself haven't found it in the package manager. If someone has experienced something similar or has a simple solution for editing cdr's I'm no artist I just need to change some names, I would be very gratefull. The full error.

• Why are so many questions closed? [closed]

  - by Kim Jong Woo

  Why is there so many questions on this stackexchange site closed? I mean far more than usual. Even very high quality discussions are closed. Doesn't this high number of closed questions with high number of views and good quality of content seem like that the current policy that governs the criteria for appropriate question might be going against nature? I mean it feels as if lot of questions or discussions are everything surrounding programmer, programming, and need not be objective or seeking definitive answer. It appears lot of questions are of inquisitive nature seeking insight into other programmers and finding common subjects of interest. Is it possible for mods to relax a bit? I mean lot of great questions with [closed] tag everywhere doesn't do justice. This question in itself is a perfect example of what I am talking about and it will be closed. But I think my point is clear.

• Designing a "Grid" like object that contains game objects

  - by liortal

  I am working on a 2D game, where there's a game "board" on which other game objects are placed. This this is 2D, my starting point was to design a class that will internally use a 2d array for the actual stored game objects. This class could be simply accessed by 2 indices: (i, j) to get game objects on it. My problem is that i have no idea how to make the game "board" "propagate" its data onto its children. Design questions i ran into are: Should the children placed on the board have display properties such as size, screen position? Should the board itself dictate this information? How to update children in case the board changes some of its properties? (position, etc). Should the board be aware of the types of objects stored in it ? I have no idea how similar things such as WPF or other UI frameworks go about organizing a "container like" object that can arrange or apply certain UI properties to its children.

• Fan very loud in Ubuntu 12.10

  - by Jon

  I recently installed 12.10 on my Desktop PC, moving away from Windows 7. For some reason, the fan in my computer is making an enormous amount of noise (it is running at full speed constantly). Under Windows 7, the fan would slow itself down and run at an acceptable noise level. Now, it is nearly unbearable. Checked the processes, and none are taking up a huge load on the CPU. Please help as I really can't endure this noise, and I do not want to go back to Windows 7 on this box. Some specs: - Intel 2.26 duo core - ATI 4870 - 4GB - 650W power supply

• How to control fan speed and temperatures on Asus A8Js laptop running Ubuntu Server?

  - by Azeworai

  Hi, I have tried installing asusfan and lm-sensors but I'm unable to control my fans to cool my laptop down sufficiently. Currently it overheats at about 100 degrees celsius and my sensors output somehow does not have any fan information on it: jackson@OLYMPIA:~$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +69.0°C (crit = +110.0°C) coretemp-isa-0000 Adapter: ISA adapter Core 0: +66.0°C (high = +100.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +66.0°C (high = +100.0°C, crit = +100.0°C) I have checked my bios and there isn't any fan settings there. I can consistently overheat just by converting a video via Handbrake. I have ubuntu-desktop installed for a GUI. Is there a way for me to control my fans to start spinning before it reaches a critical temperature and kills itself?
