• Installing programs from a download

  - by user7274

  Hello, my name is Anthony and I'm new to Ubuntu and any other Linux OS for that matter. My question concerns downloading a program, and then installing it. The program is called Remotedroid, it lets you use your phone as a wireless keyboard and mouse. I'm use to windows automatically starting setup upon download and cant figure out how to initiate the install in Ubuntu. The programs website says its compatible with Linux OS and the readme file says to just click the extension remotedroidserver.jar to use, but it wont work and none of the files do anything. I've unzipped all the files and my Java is all up to date as far as i know, I think. I'm just not getting how to run a setup in Ubuntu. I looked around this site for the answer but came up with nothing so if someone could maybe offer some insight I would be grateful. Thank you.

• Securing Facebook

  - by Promather

  Probably like most of you, I am concerned about the privacy of Facebook. Some people suggested that I use the HTTPS address instead. Unfortunately, many links in the HTTPS page itself link back to HTTP. So I am wondering whether it is possible in Ubuntu to redirect any request to: http://www.facebook.com/ to https://www.facebook.com/ This way I feel safer. If you also know the solution for Windows, it might be great to share (probably as a comment to my question rather than answer, as this forum is supposed to be for Ubuntu) so that I can share it with friends.

• Do any database "styles" use discrete files for their tables?

  - by Brad

  I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

• Is the "impossible object" possible in computer graphics?

  - by CPP_Person

  This may be a silly question but I want to know the answer to it. I saw this thing called the "impossible object", while they're many different images of this online, it's suppost to be impossible geometry. Here is an example: Now as far as logic goes, I know you don't have to obey it in games, such as a flying cow, or an impossible object. So that's out of the way, but what stands in my way is whether or not there is a way to draw this onto a 3D scene. Like is there a way to represent it as a 3D object? Thanks!

• Examining ASP.NET's Membership, Roles, and Profile - Part 18

  Membership, in a nutshell, is a framework build into the .NET Framework that supports creating, authenticating, deleting, and modifying user account information. Each user account has a set of core properties: username, password, email, a security question and answer, whether or not the account has been approved, whether or not the user is locked out of the system, and so on. These user-specific properties are certainly helpful, but they're hardly exhaustive - it's not uncommon for an application to need to track additional user-specific properties. For example, an online messageboard site might want to also also associate a signature, homepage URL, and IM address with each user account.There are two ways to associate

• First Steps. Windows Phone game development

  - by anatoliiG

  I'm pretty new in game development. Have a couple ideas wich could be cool. First that comes to mind is to develop a 2D game (kinda puzzles) for Windows Phone Mango. You may ask: "Why Windows Phone?". I answer - I've got solid experience in Silverlight and C#. For me, this is a major advantage compared to other platforms. Please, give advice and suggestions about: What should I read? Best practices. Third party libraries. Silverlight(Only) vs XNA. Whatever I should pay attention to.

• Multiple ( V- / I- ) Buffers, is it sane?

  - by Techie

  Currently I am developing an RTS game using XNA ( / ANX.Framework ). There is one thing bothers me. I am not sure in what way or how to organise Buffers. Should I use a new Vertexbuffer for any object ( e.g. a Char, a Table, an model ) or is it better to use ONE HUGE/ BIG Buffer to store any geometry in? I am still new to 3D Programming though I finished yet couple games using DirectX 9. Well, I hope this question qin't a duplicate and I appreciate any answer leading me into the right direction.

• Where would a senior PHP developer locate the method getActiveEntries()?

  - by darga33

  I have a class named GuestbookEntry that maps to the properties that are in the database table named "guestbook". Very simple! Originally, I had a static method named getActiveEntries() that retrieved an array of all GuestbookEntry objects. Each row in the guestbook table was an object that was added to that array. Then while learning how to properly design PHP classes, I learned some things: Static methods are not desirable. Separation of Concerns Single Responsibility Principle If the GuestbookEntry class should only be responsible for managing single guestbook entries then where should this getActiveEntries() method most properly go? Update: I am looking for an answer that complies with the SOLID acronym principles and allows for test-ability. That's why I want to stay away from static calls/standard functions. DAO, repository, ...? Please explain as though your explanation will be part of "Where to Locate FOR DUMMIES"... :-)

• Demographics and Interests reports

  - by Dyf

  I have an issue with Google Analytics, can't seem to find a guide how to activate Demographics and Interests reports. I am using the new version of analytics (Universal Analytics) and the script code looks something like this: (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); But the guide i found on googles page (https://support.google.com/analytics/answer/2819948?hl=sv) is for the old version (Classis Analytics). Anyone know how i can activate this on Universal Analytics or is this even possible? Thanks!

• Help deciding on an area of study for a PhD [closed]

  - by ale

  I am going to start a PhD in about 1 year. My undergraduate degree is in computer science and my master's is in artificial intelligence. I want to get ideas about what's going to be hot in say 5 years i.e. what could I spend 3-4 years studying to potentially have expertise that will be applicable to industry and the computing world ? Impossible to answer factually but some ideas and thoughts would be great. I have narrowed my ideas down to AI (yes, even more AI) and information security. AI seems to becoming popular again but security is always a going to be useful. From a career point of view, if I were to stay working in software development then this might actually be the best move but I've always wanted to do a PhD! Many thanks :).

• Multiply mode in SpriteBatch

  - by ashes999

  I have a "lighting" texture (black background with white or colours for lights) that I want to draw as a multiplcation operation. SpriteBatch.Begin can specify BlendState.Additive, but there's no BlendState.Multiplicative. I also tried the solution in this answer, but it didn't work -- even when I (incorrectly?) changed the code to work with XNA 4 style ColorDestinationBlend, I ended up with the final solution being inverted (black area where the light is, everything else is visible). I initially thought of a shader, but I couldn't get shaders to work with MonoGame, so I'm falling back to SpriteBatch.

• I want to increase the size of my boot partition (Ubuntu 14.04 version) [duplicate]

  - by Mike

  This question already has an answer here: How do I free up more space in /boot? 11 answers How to resize partitions? 5 answers I read in another post that kernels are distributed as new releases rather than upgrades. I didn't know this when I was allocating space to my partitions during my initial install of Ubuntu. As a result I ran out of space on my boot partition.

• How can I pull data from PeopleSoft on demand?

  - by trpt4him

  I work in IT at a university and I'm working with about 5 different departments to develop a new process for students to apply to a specific school within the university (not the university as a whole). We're using a web-based college application vendor and adding the applicant questions for the school itself to the main university application. Currently the main application feeds into PeopleSoft. The IT staff here is building a new table to hold just our school's applicant data. I want to be able to access that data from PeopleSoft for use in external applications, but our IT staff doesn't really seem to understand what I'm requesting, as they simply tell me I can have access to the PS query tools. The problem is, I don't want to run just ad hoc queries, I want to be able to connect from outside PeopleSoft and show current data within the external app. I am unable to find documentation or get a clear answer to my question. Does PeopleSoft support access via a web services API or anything similar, and does that sound like the right direction for me to take?

• Syncing between computers / batch download

  - by Eric

  I have synced files from two different devices. Now I want to copy to contents of the synced files to the other device. Using the web interface, it seems only possible to download one file at a time. Is there a way to setup automatic sync or to download all the files in a folder with one step? Thanks in advance for your time. I was using the web interface to ubuntu, but an answer for Ubuntu One would also be ok.

• Subdomains vs. URL Path in shareable links

  - by Adam Matan

  I am building a web application for questions and answers. Each question/answer page has all the required metadata for Facebook and Twitter, and we encourage users to share these pages. I have a dilemma regarding the shared link structure: Option 1 - subdomains Use a questions.example.com and answers.example.com, followed by an ID and optional text. The text is ignored by the request, which only takes the id into account. http://questions.example.com/<question_id>/<question_text> http://questions.example.com/12345/how-long-is-the-queue # Example http://q.example.com/12345 # Example Option 2 - URL path This is the format used by stackoverflow.com and trello.com: http://example.com/questions/<question_id>/<question_text> http://example.com/questions12345/how-long-is-the-queue # Example http://example.com/q/12345 # Example Server-wise, I can easily do both - I have a wildcard SSL certificate and Apache/NGinx configuration is pretty straightforward. Which option - subdomains or URL path - is preferred for shareble links?

• Is it safe to run multiple XNA ContentManager instances on multiple threads?

  - by Boinst

  My XNA project currently uses one ContentManager instance, and one dedicated background thread for loading all content. I wonder, would it be safe to have multiple ContentManager instances, each in it's own dedicated thread, loading different content at the same time? I'm prompted to ask this question because this article makes the following statement: If there are two textures created at the same time on different threads, they will clobber the other and you will end up with some garbage in the textures. I think that what the author is saying here, is that if I access one ContentManager simultaneously on two threads, I'll get garbage. But what if I have separate ContentManager instances for each thread? If no-one knows the answer already from experience, I'll go ahead and try it and see what happens.

• How do I remove the Skype icon from the system panel?

  - by superjudge3

  I have been trying for some time to remove the Skype icon in the upper panel in Ubuntu 11.10, but to no avail. I have went into dconf, went to desktop - unity - panel, and I looked to delete 'Skype' from the whitelist. But Skype isn't in the whitelist! And it's showing up on the panel! Something smells fishy here, and I was wondering if anyone had an answer as to a) how I can actually remove the Skype icon from the gnome panel and b) why an icon still show up there if it isn't in the whitelist? Also, if it's relevant, I use Unity. EDIT: So, the only solution for this issue is the scorched earth strategy of removing sni-qt?

• Is it a good idea to always use Google as the first step to solving a problem? [closed]

  - by The Rubber Duck

  Possible Duplicate: Importance of learning to google efficiently for a programmer? Avoiding lengthy discussions, as a senior level student in CS, how can I get away from Googling problems I run into? I find myself using it too much; I seemingly reach for the instant answer and then blindly copy and paste code, hoping it works. Anyone can do that. I've read the related threads about being a better programmer, but mostly those recommend practicing on pet projects, which I have done, but again I feel EVERY wall encountered, from design through completion, was hurdled with Google. Do professionals instantly "research" their problem? Or do you guys step back and try and figure it out yourselves? I'm talking about both 'algorithm/design' problems as well as compiler issues.

• using static methods and classes

  - by vedant1811

  I know that static methods/variables are associated with the class and not the objects of the class and are useful in situations when we need to keep count of, say the number of objects of the class that were created. Non-static members on the other hand may need to work on the specific object (i.e. to use the variables initialized by the constructor) My question what should we do when we need neither of the functionalities? Say I just need a utility function that accepts value(s) and returns a value besed solely on the values passed. I want to know whether such methods should be static or not. How is programming efficiency affected and which is a better coding practice/convention and why. PS: I don't want to spark off a debate, I just want a subjective answer and/or references.

• downgrading a ubuntu 10.04 LTS virtual server

  - by castigli

  I am downgrading an existing ubuntu 10.04 LTS Virtual Server to one with less memory and a smaller drive ( from 80GB to 40GB ). My hoster ( hetzner.de ) does not give me the possibility of doing an inplace downgrade, so I have to create a new server. What is the best way to make an image of the first system and "apply it" to the new one ? I know there other answer but in my situation I am not sure I would be able to use Clonezilla or other GUI tools, because the installation is minimal with no GUI. Thanks in advance Michele

• How can I get stats for what 3rd-party sites have embedded our iframe widget?

  - by Su'

  Say we've produced a widget for other sites to use, like so: <iframe src="http://example.com/whatever.php" frameBorder="0" width="200px" height="300px" scrolling="no"></iframe> The client would like to be able to see within GA who has embedded the thing. Is there some referer information automatically passed that I can look for, or do I need to add something? whatever.php is already loading the analytics Javascript(we're also tracking clicks on an outbound link). [EDIT] Looking around a bit more, I found what seems to be a similar question on SO with an answer saying this can be found, automatically, but I still can't seem to find the information. The question's also old enough the respondent is probably referring to the old interface, though. Maybe someone could explain getting to it in the new look. (I won't likely be able to train this client to switch, deal with the old look, etc.)

• How to change color of the frame of a maximizing window

  - by SteliosSk

  Though I have read and tried some advises regarding the change of colors in a theme, I found no answer regarding my question, which is: When I drag a window to the left (or right or up) side of the screen an orange frame shows up, indicating the area that the window will occupy. This frame is in orange. Can you please inform me how can I change this color to blueish, to match my theme? At this point, I would like to inform you that Zorin OS has this blueish frame instead of orange, but I do not know where this color comes from.
