• Is Java much harder to "tweak" for performance compared with C/C++?

  - by user997112

  Does the "magic" of the JVM hinder the influence a programmer has over micro-optimisations in Java? I recently read in C++ sometimes the ordering of the data members can provide optimizations (granted, in the microsecond environment) and I presumed a programmer's hands are tied when it comes to squeezing performance from Java? I appreciate a decent algorithm provides greater speed-gains, but once you have the correct algorithm is Java harder to tweak due to the JVM control? If not, could people give examples of what tricks you can use in Java (besides simple compiler flags).

• How a graphic designer can get into game programming?

  - by Robert Valdez

  I'm a graphic design student hoping to pursue a career as a video game artist. However, I want to do some game development as a hobby. I'd like to develop games for the desktop or mobile phones. The only programming experience I have is that I took an intro to programming with java class in which I learned how to make web applets using java's swing library. It was awful. I think the only things I took from the class was what OOP is and how to work with variables and data types and some methods. I also learned some actionscript myself which was fun unfortunately my flash tutorial expired and it's too expensive to buy;( What I was looking to do is learn one programming language and build a game with it without having to go through so many hoops and with minimum cost. If it's possible. I would love to learn C++, but I read it's not best for a beginning programmer. What programming languages or maybe software kits/platforms would you recommend?

• Ubuntu Server 12.04 Samba Server timeout

  - by phileaton

  I am a beginner with servers. I checked the error logs for Samba and it appears that Samba is timing out when I transfer large files. I can successfully add PDFs for instance to my file server. However, I tried to add a large 1.2Gb video file and it did not succeed. This is the error in the log: smbd/process.c:244(read_packet_remainder) read_fd_with_timeout failed for client 0.0.0.0 read error = NT_STATUS_CONNECT$ Is there a way I can stop it from timing out? Any pointers would be great! Thanks!

• Having trouble with font on this blog?

  - by TechTwaddle

  Sometimes when I open this site on other PC’s the font of the posts turns out be very small and it can be a pain to read the text. Not sure if you’ve noticed the ‘Customize’ bar on top of the page, so I thought I’ll let know. This bar helps you customize the way you want the page to look and saves the settings for you so you don’t have to change it every time. You can change the font size and the main page positioning. The white arrow marks in the image above shows the settings I find convenient.

• Can't edit/drag-and-drop widgets in QtCreator in Unity, Gnome3 - ok

  - by Maksim

  I have QtCreator 2.4.1 (Qt 4.7.4) installed on Ubuntu 12.04 LTS x86. When I try to change UI - drag-and-drop any widget (buttons, label, etc.) it won't let me do it, like it's read-only. The icon when I drag is a circle with a line through it. I've found that problem in Unity and it's suggested to install Gnome3 shell - Can't edit/drag-and-drop widgets in QtCreator I tried to install Gnome3 and it works fine as expected. But the question, is there any other way to work proper with QtCreator in Unity?

• Upgrading from Express Edition to Standard Edition

  - by TiborKaraszi

  Say you encounter an SQL Server which is Express Edition, and it really should have been some higher edition. Sounds familiar? It is common for me as a consultant to find plenty of SQL Servers at a customer's site. Many of the databases in these will be moved (typically using backup and restore) to a "real" SQL Server. But in some cases, this might not be desirable. You want to convert the whole instance, from Express to a "real" SQL Server edition. I'm attending a great SharePoint course for Daniel...(read more)

• Open-Source, Consensus-Based Development

  - by user20037

  Question: Is there an open source license that requires that my name (or a name that I want to promote) will always be associated with a project and derivations of it? (Either within the copyright notice (©) or other.) Motivation: - My main motivation is to gain reputation. If it gained wide use, it could look very good on resume (I understand this is a long shot). - An additional benefit is that it would explicitly state to prospective employers that this code was used by myself before I started with the company and will continue to be used when I leave. It is my understanding: I am aware that 99.9% of open-source projects never take off, and that I am taking a long shot in regard to advancing reputation/career. I understand that many don't read/respect licenses. I understand that open source projects take a lot of time to manage. I understand that 'Concensus-Based Development' is the best chance at motivating a community and that I may/will loose substantial control.

• Sending Graphics to the C drive [on hold]

  - by CodeOfGenius

  I'm trying to create image files on the users' desktop. Let's say i have a picture of an orange in my eclipse workspace in the resource folder. When somebody downloads the project, I want to take that image of an orange and put it in a folder called fruit on their desktop. Whenever i export my game it can't read the images anymore which is wierd so I prefer to try this method. Just like minecraft has its' stuff in %Appdata%, I want to put a folder with my images the game uses on the desktop. There isn't any errors, I'm just asking how do i do this.

• HP Pavilion dv7 dual boot with ubuntu and original win7 issues

  - by Neasy11

  I just bought a hp dv7 and I want to dual boot it with the win7 it came with and ubuntu 12.04.1. I shrunk the C partition to make room for the ubuntu one then downloaded an burnt the iso. Next I booted from the cd and followed the simple instructions until I got to the page of the install to choose the partition where all choices were greyed out and the table was completely blank and the drop down only had one choice. After researching this I found that a main problem might be that I can only have 4 primary partitions and the computer was shipped with the 4 already (system,C,recovery,hp tools). I guess my question is what is the best way to go about completing this dual boot? I have read to delete the hp tools partition or combine it with another, I just want a step by step of how to dual boot this computer, I have done plenty of computers in the past but never ran into these issues that come with an HP (should have got a dell lol)!

• 1 Zettabyte Is Equal to 1 Million Petabytes

  - by Gopinath

  Geeks recently coined a new English term, Zettabyte, to measure the rapidly growing digital information footprint. So what is a Zettabyte? A Zettabyte is equal to 1 million Petabytes or 1 trillion terabytes and 1 quadrillion gigabytes. Symbol To Represent Zettabyte According to wikipedia the symbol ZB is used to represent a Zettabyte. So we can write 10 ZB to represent 10 Zettabytes. Human’s Digital Output Will be 1.2 Zettabytes By End Of 2010 Are you wondering why do we need a term to measure digital data? Tech research firm IDC has recently published a report that estimates current digital footprint created by us so far at 8 million Petabytes – the equivalent of 8,000,000,000,000 GB. This foot print is expected to pass 1.2 Zettabytes by the end of 2010. cc image credit:flickr Join us on Facebook to read all our stories right inside your Facebook news feed.

• What grammatical tense should I write my specifications in?

  - by John

  We are currently writing functional and technical specifications in a two column format; summary sentence and technical detail. The details often refer to an appendix with diagrams, layout designs ect. However I am struggling with what tense to write it in: With past tense as if the work is done I struggle to show highlight extensions of exiting work. Future tense as in it needs to do X starts to sound like a to do list or Tense neutral very hard as it has either going to be done or is done. To add further confusion this specification may be read by people who do not have English as a first language.

• .NET mulithreading and quad core processors

  - by w0051977

  I have a single threaded application that runs on a machine with a quad core processor. The scheduled tasks that run VB.NET forms are too slow. I am new to multi threading and parallel computing. If you have a single threaded application that runs on a server with a multi core processor then does the application only ever use one of the processors? What happens if you have multiple scheduled tasks and multiple instances are in memory at the same time? I have read this question on Stackoverflow: http://stackoverflow.com/questions/607775/how-to-write-net-applications-that-utilize-multi-core-processors, but I am still not clear.

• Installed fprint, can't login anymore

  - by Otto

  Tried Fprint, was stupid enough not to backup the common-auth file before changing it. Somehow I'm locked out of the system, trying to fingerscan doesn't do any difference. Even when I've done it 5 times and it asks for password, when it asks for password and I write it in and it says that it's the wrong password. I use the same password for root as for my user. Tried to go into Recovery Mode - root - sudo nano /etc/pam.d/common-auth and remove the rows saying that you need the fingerprint to login, but when I try to overwrite, it says the file is read only, even when I try to open it with root. I have a lot of schoolwork files and programs on the system, so I can't afford losing them. Help?

• How do I create a new usergroup?

  - by Sergiu

  I want to do this because I'm trying to fix user permissions from Ubuntu on my Mac OS X partition and Ubuntu doesn't have the "wheel" group that I so desperately need! Please don't trash me for this but I set my whole Mac OS X partition to give read and write access to everyone so I could access and modify everything on it from my dual-booting Ubuntu OS, and now everything is screwed... I don't have the original Mac OS X installation DVD and booting a Mac OS X 10.5.6 DVD gives me kernel panics... The OS installed on that Mac partition is 10.4.11. Is there any hope for me to ever fix it? I don't have money to buy utilities, and I can't use AppleJack either because my permissions are so messed up... None of the posted answers are what I wanted to do. I wanted to add fields to a user that was on my Mac partition, not a user part of the Ubuntu groups. Is that possible?

• Caller Info Attributes in C# 5.0

  - by Jalpesh P. Vadgama

  In c# 5.0 Microsoft has introduced a Caller information attribute. It’s a new feature that is introduced in C# 5.0 and very useful if you want to log your code activities. With the help of this you can implement the log functionality very easily. It can help any programmer in tracing, debugging and diagnostic of any application. With the help of Caller Information we can get following information over there. CallerFilePathAttribute: With help of  this attribute we can get full path of source file that contains caller. This will be file path from which contains caller at compile time. CallerLineNumberAttribute:  With the help of this attribute we can get line number of source file which the method is called. CallerMemberNameAttribute: With the help of this attribute we can get the method or property name of the caller. Read more

• Tic-Tac-Toe game AI

  - by David Jones

  I'm looking into creating a simple tic tac toe/noughts and crosses game in Actionscript3 and am trying to understand the ideas behind the AI used in a game like this. I've seen some simplistic examples online but from what I've read a game tree or something like minimax is the best way to go about this. Can anyone help explain or reference any good examples of this? I've seen that there is a library called as3ds - data structures for game developers which has a number of classes that might help tie this together? Any info/examples or help is much appreciated.

• How do I boot the live CD on a Macbook Pro?

  Trying to install Ubuntu-11.10-64bit-MAC on a Macbook Pro. But I cannot get the live CD to load. 'C' does not work 'CMD' does not work 'OPT' no opt key CD is not corrupt and burnt using the correct iso, all checked. Installed perfectly on my Acer PC.... God I hate Apple Macs!

I do not have any MAC OS installed in this PC only Ubuntu 10.10. When I press 'alt' the CD does not appear in the list only my HDD, yes my CD is working fine.

• Crappy school, what to do? [closed]

  - by zhenka

  I started programming fairly late. I am 24 years old and about to graduate from a local public university with a really poorly designed curriculum and teachers. Most of the work felt like busy work, and no matter how much I try, it all feels like a waste. I know what a good curriculum looks like. I know what books I should read, but alas it's not so in my university. There is no way at this point that I can catch up to those graduating from places like MIT. My question and this is a serious one: what do I do? Do I just postpone learning the theory I would have learned until later and focus on software engineering skills? How important is the theory in terms of landing a job in New York? Any particular things I should focus on to land a software engineer job? I am very motivated and I just wish someone would give me the time and a chance.

  So, I have been away from blogging about technical stuff for a  long time,  (I haven’t blogged at all since my resolutions blog , and even my Simple Talk “commentary” blog hasn’t had an entry since December!)  Most of this has been due to finishing up my database design book , which I will blog about at least one more time after it ships next month, but now it is time to get back to it certainly in a bit more regularly.
