• Can I launch Windows 8 with grub?

  - by Laurbert515

  I accidentally deleted the boot loader for Windows 8 (I think). Here is the situation: I just got a new computer with 2 HDD (sda, sdb). Now, all of the windows OS was installed on sdb (all except for about 210 MB on sda). I formatted sda and installed Kubuntu 12.04.2 (which only loads the terminal because it says it can't find a screen, but that's another story!) Now, my Windows 8 data and NTFS partitions, etc. are still on sdb and untouched. Unfortunately, I cannot see an option to boot into Windows 8 in grub, so is there a way that I can go about using grub to point to the Windows 8 OS? The only other option I can think of is to buy a fresh copy of Windows 8 and install it fresh (no, I didn't create a backup USB because I'm an idiot ...)

• Auto mount USB drive with permissions for all users

  - by oneaustin

  I have an Ubuntu 14.04 based Media Center and I store the media files on a USB HDD. I add files to drive directly on a Mac so I have it formatted as FAT32. The problem is that after reconnecting the drive to the Ubuntu, it mounts at /media/user/drivename and only the root user is allowed access. I need several applications to have full access to this drive. I can change file permissions in the terminal but it doesn't change because of the /media/user location. I am able to manually sudo mount /dev/sdc1 /media/drivename & sudo chmod 777 /media/drivename but the mount point changes each time. Is there a way to make this drive always mount where root and other applications have access?

• Upgrade from 13.04 to 13.10 fails early on

  - by Bob Lewis

  I am attempting to upgrade from 13.04 to 13.10. Right after the early on message Downloading file 1 of 2 and then it goes on to 2 of 2 the upgrade process dies. A reboot and attempt again fails at the same point. This is a 64 bit system with an SSD for the boot drive. If memory serves me when attempting to do same from the command line I saw some dbus error which may or may not be related. Any help much appreciated. Obviously I could attempt a fresh install which would likely succeed.

• Just wondering about "Do-It Yourself Apps" on the internet versus apps written by us developers

  - by user657514

  Hi, I have been doing Objective-C programming over the past few weeks, and I have learnt a lot. However, I see that there are other Web-companies offering services to consumers directly from their website that allow consumers to create their apps through a point and click and drag features without any code. Clearly they are more cost effective and fast than having a developer write an app. I was wondering if there are any advantages then of having a developer build an app for someone, other than the obvious advantage that its got a custom look and feel. Could someone please clarify, since Im new and would like to evaluate whether it is worthwhile spending time towards learning a whole new development environment when someone could just use a webservice to make an app for multiple platforms Thanks

• Can Agile/Scrum be used by 1 or 2 developers?

  - by Dillie-O

  Everything I've been reading and researching up to this point describes how Agile/Scrum works great with teams of about 4 to 6 members, maybe even more. In my current shop, we have about 8 developers or so, but given the nature of the volume of projects and the number of departments we support, we never have more than 1 or 2 folks assigned to a given project. Can I still use Agile/Scrum with a team of 1 or 2 developers? I'm working on making the pitch to my manager to start working with this methodology, but I need to be able to explain how to scale things back for a small developer crew, or convince them to make sure we get more members on a given project.

• Generic Content Player?

  - by Jantire

  The general idea on the web appears to be that video/audio are to be separated with plain text. By separated, I mean you have a place that plays video/audio and a place that you read text. This is because it is widely understood that they are vastly different. However, audio and video are just another way of communication, just like text. So why do we separate the two even if they are nearly the same thing? Correct me if I'm wrong but, most tutorials are either plain text how-to's (wiki-style) or visual/auditory instructional videos (YouTube). Why aren't the two combined? Or, if it's already been done can someone reply with the link? This might be bordering off-topic and if it is off-topic then please point me to the right place so it won't be. This might also appear to be an obvious question, however I'm not sure if this subject has really been deeply thought-out by more than a few individuals.

• Restricted pathfinding Area

  - by SubZeron

  So i'm triying to create a little "XCOM : Enemy Unknown" like game ,and using the Aron Granberg's Pathfinding-Tool (free version) to handle the "click to move part. i want to add a little trap system where the hero get stuck inside an area, so he will have only the possibility to move inside this trapped area, so far everything is fine however when i click outside the trapped area, the hero try to reach the destination even though the wall will prevents him from reaching it. so my question is, is there any way to restrict the area where the pathfinding system work to the trapped area dynamically. and wich Graph Type is recommended to use in this situation or this kind of Games (Grid Graph/Navmesh Graph/Point Graph). Thank you. image link for explanation : https://dl.dropbox.com/u/77993668/exemple.jpg

• How to find 2D grid cells swept by a moving circle?

  - by Nevermind

  I'm making a game based on a 2D grid, with some cells passable and some not. Dynamic objects can move continuously, independent of the grid, but need to collide with impassable cells. I wrote an algorithm to trace a ray against the grid, that gives me all cells that ray intersects. However, actual object are not point-sized; I'm currently representing them as circles. But I can't figure out an effective algorithm to trace a moving circle. Here's a picture of what I need: The numbers show in what order the circle collides with grid cells. Does anybody know the algorithm to find these collisions? Preferably in C#. Update The circle can be bigger than a single grid cell.

• Visual C++, CMap object save to blob column

  - by ilansch

  I have a MFC CMap object, each object stores 160K~ entries of long data. I need to store it on Oracle SQL. we decided to save it as a blob. since we do not want to make additional table. we also thought about saving it as local file and point the SQL column to that file, but we rather just keep it as blob on the server and clear the table every couple of weeks. The table has a sequential key as ID, and 2 column of time. I need to add the blob column in order to store on every row that CMap. Can you recommend a guide to do so (read/write Map to blob or maybe a clob) ? Thanks.

• Is there such a thing these days as programming in the small?

  - by WeNeedAnswers

  With all the programming languages that are out there, what exactly does it mean to program in the small and is it still possible, without the possibility of re-purposing to the large. The original article which mentions in the small was dated to 1975 and referred to scripting languages (as glue languages). Maybe I am missing the point, but any language that you can built components of code out of, I would regard to being able to handle "in the large". Is there a confusion on what Objects are and do they really figure as being mandatory to being able to handle "the large". Many have argued that this is the true meaning of "In the large" and that the concepts of objects are best fit for the job.

• How to Build Business Links With SEO Value

  In order to create order and plan in the site and make it more identifiable by a business community around, SEO link building requires membership strategies that aid it in its automatic operations by following a universal hub with potential links. The starting point is to obtain a link with the national or regional authority of commerce through its website. This will give the site a licensed look and due to its frequent interaction with the government body it will be a confidence boost for other links. This will also help market it as a recognized site that is secure to communicate with.

• Experience embedding javascript

  - by deft_code

  I'm looking into scripting languages to embed in my game. I've always assumed Lua was the best choice, but I've read some recent news about embedding V8 as was considering using it instead. My question is two fold: Does anyone with experience embedding v8 (or another javascript engine) recommend it? How does it compare with embedding Lua? I like that v8 has a c++ embedding API. However Lua API has had lots of time to be refined (newer isn't always better and all that). Note: At this point I'm not too concerned with which is better language or which library has better performance. I'm only asking about ease of embedding.

• Guidelines or Design pattern to develop configurable software

  - by Rumit Parakhiya

  I want to develop an application which would have it's own framework, using which developer can implement functionality very easily. Developer shouldn't have to code for each and every page or report. But, he can do it very easily by just configuring it using the framework provided. Some nice examples of it is SAP and Tally. They have got their own framework, using which anybody having knowledge of it can customize or extend functionality of the product. But, as I am beginner in this direction, I don't have any idea about where to start. Can anybody point me to some design pattern which I can follow or some similar open source software which I can refer?

• Microsoft Launches Outlook.com

  Microsoft announced the news in its Outlook blog, calling the new service modern email for the next billion mailboxes. The company is touting a fresh, clean user interface with fewer pixels in the header and no display ads; it should work well on portable devices. Another key point: it uses Exchange ActiveSync to synchronize your mail, calendar and social experience across your smartphone, tablet and desktop computer. Perhaps the biggest advance, though, is that Microsoft is connecting the email service to Facebook, Twitter, LinkedIn, Google; Skype will be part of this list, too, though i...

• Retrieve the coordinates of the *occluding* (closest/drawn) pixels during 3D overlap, using OpenGL?

  - by Big Rich

  Hi, Sorry if the question is not worded well, I'm a new to both 3D and OpenGL. How could I go about obtaining the 3D coordinates of the occluding object, at the point where occlusion is happening (i.e. the 'intersection' of the object in front/closest to the screen)? Just to offer a [very] rudimentary, visual, example, if you were to form an index-finger cross, with your right hand closest to your face, I'd like to know the coordinates of the part of your right finger which obscures the other finger (obviously back within the OpenGL context - no jokers ;-) ). If there is a way to find out both about the occluder (hider) and the occluded (hidden) objects in OpenGL, then that would be of great use, also. Cheers Rich

• 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 :).

• How to cope with "Hidden IT..." Who writes and maintains the ad-hoc software applications?

  - by matcauthon

  Bigger companies usually have the problem, that it is not possible to write all programs employees want (to save time and to optimize processes) due to a lack of staff and money. Then hidden programs will be created by some people having (at least some) coding experience (or by cheap students/interns...). Under some circumstances these applications will raise in importance and spread from one user to a whole department. Then there is the critical point: Who will maintain the application, add new features, ...? And this app is critical. It IS needed. But the intern has left the company. No one knows how it works. You only have a bunch of sources and some sort of documentation. How do you cope with these applications? Can you "forbid" them? Can you control them? Do you have to write all apps (not Excel macros or some minor stuff) in the IT department?

• Are there Any Concerns with Importing Document Files From a Competing Product?

  - by Thunderforge

  I have a new product that serves the same purpose as my competitor's long-standing product. One thing I have considered doing is allowing my program to import document files created by their product in order to provide an easy way for users to migrate towards mine. Naturally, this would be done without the competitor's permission, as it goes against their interests. I've seen this done before with office suite software (e.g. Open Office and Apple Pages can import MS Word documents), but I'm wondering if there are any concerns, legal or ethical, with me doing this. I fully expect any answers will most likely fall under the "I am not a lawyer" clause, but it would be helpful to have a starting point for anything I would need to be aware of, or if I shouldn't need to worry.

• Jquery/JavaScript's role in MVC (zend)

  - by user7543288

  I have my doubts if this question should have went into the programmers.stackexchange.com or not…but I would like to ask all you experienced developers out there, how do you see the connection that jquery - javascript has with the MVC. How would you explain it to a n00b? does it bridge the communication between the View and the Controller? or what? I have done my research and I believe this is the best article explaining it http://www.alistapart.com/articles/javascript-mvc/ but I would like to hear your point of view..

• Personal Activity Monitor tracks time you spend using desktop apps

  Up until a couple of years ago, I used to turn to RescueTime to figure out how I spend my time online. Then it got too complex, and I stopped using it. Personal Activity Monitor is like a vastly dumbed-down version of RescueTime, and I mean that as a compliment. It's free and bare-bones -- all it does is track what applications you're using and for how long. A big drawback at this point is that it doesn't integrate with Web browsers to help you analyze how you spend your time on the Web. Still, if your work doesn't require constant Web app use, knowing how long you've used a browser overall might be enough to help you manage your time. This is far from the only application in this space -- alternatives such as Slife and Chrometa are full-featured and impressive -- but PAM is good option for those who want a nice, simple tracker.Personal Activity Monitor tracks time you spend using desktop apps originally appeared on Download Squad on Sat, 05 Mar 2011 10:00:00 EST.

• Usb/vga not recognized anymore

  - by Peter Raeves

  I don't know what happened, but yesterday everything worked fine, but when I woke up this morning and booted my computer to Ubuntu 14.04 a bunch of hardware isn't recognized anymore. I use a dual monitor setup with dvi-d and vga, but the vga screen isn't recognized anymore and the dvi-d monitor is recognized as "Built-in Display" while I'm not on a laptop. Also every device connected through usb isn't recognized anymore either. I have a keyboard with the blue round connector, which still works, so I can still log in though. The computer goes slower than usual and I have no idea what has happened. Can anybody point me in the direction I should start looking, because this is scary! I just checked and both the front and back sound connectors stopped working also :/ Edit: The devices connected through USB are recognized as they all show up using sudo lsusb, Ubuntu just doesn't let me use them anymore.
