• Dedicated GRUB2 Partition and Windows 8

  - by captain

  Ok so as many of you may know the Windows 8 developer preview was released today and as such I'm very eager to use it but I have both Ubuntu and Windows 7 installed on my machine. I don't want to disturb these drives and have recently set up a dedicated grub partition on /media/sdb8 My question is if I install windows 8 will it overwrite the grub partition and if so what are the steps I should take to recover it.

• What is a software prototype?

  - by Stack Stock

  I understand this site is for programmers, and i have to ask specific coding question. I am doing a software engineering degree and i have been asked to reference at-least 7 books in my definition of prototyping. The best place to ask is here because most of you have probably read books on this and would be able to recommend books to me. I dont mind buying them from Amazon so if you could some books for me that define prototyping or a prototype i would really appreciate it.

• How often do you use data structures (ie Binary Trees, Linked Lists) in your jobs/side projects?

  - by Chris2021

  It seems to me that, for everyday use, more primitive data structures like arrays get the job done just as well as a binary tree would. My question is how common is to use these structures when writing code for projects at work or projects that you pursue in your free time? I understand the better insertion time/deletion time/sorting time for certain structures but would that really matter that much if you were working with a relatively small amount of data?

• IEnumerator.Current property and IEnumerator.MoveNext method

  - by nmarun

  Here’s a question: What happens to the Current property of an IEnumerator before and after the MoveNext() call? When I say ‘after the MoveNext() call’, I mean after MoveNext() returns a false indicating an end of the collection. I was going through the MSDN for IEnumerator.Current and the first paragraph basically boils down to: If MoveNext() method has never been called on an IEnumerator, the Current property is undefined. I wanted to know what ‘undefined’ means – is it null? If so, what if the...(read more)

• Why the static data members have to be defined outside the class separately in C++ (unlike Java)?

  - by iammilind

  class A { static int foo () {} // ok static int x; // <--- needed to be defined separately in .cpp file }; I don't see a need of having A::x defined separately in a .cpp file (or same file for templates). Why can't be A::x declared and defined at the same time? Has it been forbidden for historical reasons? My main question is, will it affect any functionality if static data members were declared/defined at the same time (same as Java) ?

• switch HDD in laptop

  - by jolly

  the internal hard drive that I have right now in my laptop is coming near its death, clicking for life, so I decided to buy a new HDD. However, I don't want to spend two weeks setting up my system to fit me as it does right now, so I thought that I can make just a hard copy of all the contents to the new disk (using dd). My question is: is it going to work? :-) What are the things that need to be changed, except fstab?

• PASS Summit for SQL Starters

  - by Davide Mauri

  I’ve received a buch of emails from PASS Summit “First Timers” that are also somehow new to SQL Server (for “somehow” I mean people with less than 6 month experience but with some basic knowledge of SQL Server engine) or are catching up from SQL Server 2000. The common question regards the session one should not miss to have a broad view of the entire SQL Server platform have some insight into some specific areas of SQL Server Given that I’m on (semi-)vacantion and that I have more free time (not true, I have to prepare slides & demos for several conferences, PASS Summit  - Building the Agile Data Warehouse with SQL Server 2012 - and PASS 24H - Agile Data Warehousing with SQL Server 2012 - among them…but let’s pretend it to be true), I’ve decided to make a post to answer to this common questions. Of course this is my personal point of view and given the fact that the number and quality of session that will be delivered at PASS Summit is so high that is very difficoult to make a choice, fell free to jump into the discussion and leave your feedback or – even better – answer with another post. I’m sure it will be very helpful to all the SQL Server beginners out there. I’ve imposed to myself to choose 6 session at maximum for each Track. Why 6? Because it’s the maximum number of session you can follow in one day, and given that all the session will be on the Summit DVD, they are the answer to the following question: “If I have one day to spend in training, which session I should watch?”. Of course a Summit is not like a Course so a lot of very basics concept of well-established technologies won’t be found here. Analysis Services, Integration Services, MDX are not part of the Summit this time (at least for the basic part of them). Enough with that, let’s start with the session list ideal to have a good Overview of all the SQL Server Platform: Geospatial Data Types in SQL Server 2012 Inside Unstructured Data: SQL Server 2012 FileTable and Semantic Search XQuery and XML in SQL Server: Common Problems and Best Practice Solutions Microsoft's Big Play for Big Data Dashboards: When to Choose Which MSBI Tool Microsoft BI End-User Tools 360° for what concern Database Development, I recommend the following sessions Understanding Transaction Isolation Levels What to Look for in Execution Plans Improve Query Performance by Fixing Bad Parameter Sniffing A Window into Your Data: Using SQL Window Functions Practical Uses and Optimization of New T-SQL Features in SQL Server 2012 Taking MERGE Beyond the Basics For Business Intelligence Information Delivery Analyzing SSAS Data with Excel Building Compelling Power View Reports Managed Self-Service BI PowerPivot 101  SharePoint for Business Intelligence The Best Microsoft BI Tools You've Never Heard Of and for Business Intelligence Architecture & Development BI Power Hour Building a Tabular Model Database Enterprise Information Management: Bringing Together SSIS, DQS, and MDS SSIS Design Patterns Storing Columnstore Indexes Hadoop and Its Ecosystem Components in Action Beside the listed sessions, First Timers should also take a look the the page PASS set up for them: http://www.sqlpass.org/summit/2012/Connect/FirstTimers.aspx See you at PASS Summit!

• Attaching new animations onto skeleton via props, a good idea?

  - by Cardin

  I'm thinking of coding a game with an idea of mine. I've coded 2D games before, but I'm new to 3D programming, so I'd like to ask if this idea of mine is feasible or out of my depth. I'm making a game where there are many different characters for the player to choose from (JRPG style). So to save time, I have an idea of creating many different varied characters using a completely naked body mesh and animation skeleton, standardised across all characters. For example, by placing different hair, boots, armor props on the character mesh, new characters can be formed. Kinda like playing dress-up with a barbie doll. I'm thinking this can be done by having a bone on the prop that I can programmically attach to the main mesh. Also, I plan to have some props add new animations to the base skeleton, so equipping some particular props would give it new attack, damage, idle animations. This is because I can't expect the character to have the same swinging animation if he had a big sword or an axe. I think this might be possible if the prop has its own instance of the animation skeleton with just only the new animations, and parenting the base body mesh to this new skeleton. So all the base body mesh has are just the basic animations, other animations come from the props. My concerns are, 1) the props might not attach to the mesh properly and jitter a lot, 2) since prop and body are animated differently, the props and base mesh will cause visual artefacts, like the naked thighs showing through the pants when the character walks, 3) a custom pipeline have to be developed to export skeletons without mesh, and also to attach the base body mesh to a new skeleton during runtime in the game. So my question: are these features considered 'easy' to code? Or am I trying to do something few have ever succeeded with on their own? It feels like all these can be done given enough time and I know I definitely have to do a bit of bone matrix calculations, but I really don't want to drag out the development timeline unnecessarily from coding mathematically intense things or analyzing how to parse 3D export formats. I'm currently only at the Game Design stage, so if these features aren't a good idea, I can simply change the design of the game. (Unrelated to question) I could always, as last resort, have the characters have predetermined outfit and weapon selections so as to animate everything manually.

• Textual descriptions of 8-bit and 16-bit game engines

  - by ixtmixilix

  I found a good description of the engine in the Sonic games. It describes roughly how the engine works for people writing their own clones. In my case, I am simply interested in getting a general view of how the many 8-bit and 16-bit game engines worked on their respective consoles. So, this is a big-list style question asking, what other online descriptions of specific game engines have people found?

• How can I make sure one Upstart job starts before other Upstart jobs?

  - by marrusl

  This is a general Upstart question, but let me use a specific case: Centrify is an NIS to ActiveDirectory gateway. It needs to load before any service that will depend the authentication service that it provides, e.g. autofs, cron, nis, et al. This has proven to be quite challenging to achieve, even when trying to change the dependencies of the other services (which I don't think we should be doing anyway, I don't want to touch the other Upstart jobs if at all possible). Suggestions?

• Does searching documentation and samples look bad?

  - by Mick Aranha

  I am starting a new job in a company with many developers and media people, the layout of the place is open with computers around a skinny oval, I have worked in small teams and programming embedded C, the jobis for objective C I'm still in a medium stage, so I know what I don't know (haha), that means I have to google it and then implement it, So the question is how bad does it look if the guy next to you does lot of searching for coding I mean, at the end of the day I will get the job done, but want to look professional too!

• Normal vector of a face loaded from an FBX model during collision?

  - by Corey Ogburn

  I'm loading a simple 6 sided cube from a UV-mapped FBX model and I'm using a BoundingBox to test for collisions. Once I determine there's a collision, I want to use the normal vector of the collided surface to correct the movement of whatever collided with the cube. I suppose this is a two-part question: 1) How can I determine which face of the cube was collided with in a collision? 2) How can I get the normal vector of that surface?

• How can I obtain mp3 metadata to rename them? [closed]

  - by Blaze

  I am planing on writing an application using Vala. Its purposed is to import mp3 files from a location and rename them if necessary. The renaming information should be provided by the ID3 tags in the mp3 file such as the title and the number of the song. My target platform is Ubuntu (Linux). As the question says, I am searching for how can I achieve this on Vala. I think this functionality might be provided by Gstreamer.

• Part 5: Choose the right tool - or - why

  - by volker.eckardt(at)oracle.com

  Consider the following client request “Please create a report for us to list expenses”. Which Oracle EBS tool would you choose? There are plenty of options available: Oracle Reports, or BI Publisher with PDF or Excel layout, or Discoverer, or BI Publisher Stand Alone, or PDF online generation, or Oracle WebADI, or Plain SQL*Plus as Concurrent Program, or Online review option … Assuming, you as development lead have to decide, you may decide by available skill set in your development team. However, is this a good decision? An important question to influence the decision is the “Why” question: why do you need this report, what process is behind, what exactly you like to achieve? We see often data created or printed, although it would be much better to get the data in Excel, and upload changes via WebADI directly. There are more points that should drive your decision: How many of such requirements you have got? Has this technique been used in the project already? Are there related reusable’s you may gain from? How difficult is it to maintain your solution? Can you merge this report with another one, to reduce test and maintenance work? In addition, also your own development standards should guide you a bit to come to a good decision. In one of my own projects, we discussed such topics in our weekly team meeting. By utilizing the team knowledge best, you may come to a better decision, and additionally, your team supports your decision. Unfortunately, I have rarely seen dedicated team trainings or planned knowledge transfer to support such processes. Often the pressure to deliver on time is too high to have discussion and decision time left. But exactly this can help keeping maintenance costs low by limiting the number of alternative solutions for similar requirements. Lastly, design decisions should be documented to allow another person taking this over easily. Decisions shall be reviewed and updated regularly, to reflect related procedures or Oracle products respective product versions. Summary: Oracle EBS offers plenty of alternatives to implement customizations. Create and maintain a decision tree to support the design process. Do not leave the decision just on developer side. Limit the number of alternative solutions as best as possible; choose one which is the most appropriate also from future maintenance perspective.

  Discussions and reports about UEFI and Secure Boot has cropped up in many Linux circles, but can anyone summarize it's impacts on Ubuntu and how it affects the general users? I know that UEFI and Secure Boot are separate (not interchangeable), with Secure Boot being a part of the Unified Extensible Firmware Interface BIOS specification.

• What Interface Toolkit is being recommended for Ubuntu on Nexus7/Mobile Devices?

Hope someone out there know this! Cheers
