• Can I properly use NS2 on latest Ubuntu 12.04?

  - by Nwe Nwe

  I am a novice user for Ubuntu because I need to work with NS2. NS2 properly work only in Linux, Ubuntu. Now, I wonder if it can properly work on latest version Ubuntu. My current window is Window7. I also want to use Window7. So, which one will be better on parallel booting of Window 7 and Ubuntu or using VMWare on Window7 to install Ubuntu. My RAM is 4G. My processor speed is 1.6G. If I use VMWare, my C drive is only extra 10G. So, does VMWare can work properly in D drive? Please let me know which way is the best for my situation. I hope the advice from anyone. Thanks in advance.

• Fast language for problem solving? [closed]

  - by Friend of Kim

  I learned PHP to make websites. After some years I've started using programming for solving what is difficult tasks for my level. Now I want to make a program that solves equations. (I want to write it myself, not use an API. Because I'm doing this for the sake of the challenge, not for the result..) Because of this, I'm going to learn a new and faster/better language. It's going to be C++, Java, Python or C#. What are the benefits of each language, and which language is best for speed compared to speed of writing and readability? Using C would be lightning fast, but the lack of OO is making for more complex code and reduces the readability, for example..

• How to debug slow session start of Gnome 3?

  - by user65521

  After Upgrade from 11.10 to 12.04, the login process of Gnome 3 is extremely slow (It takes in the order of 60 seconds when it was in the order of a few seconds before the upgrade (Harddisk is a SSD!)). Running "top" in a VT shows that gnome-shell is producing about 90% CPU load while dbus-daemon is taking roughly 10%. The moment when CPU-load of gnome-shell drops to normal levels (around 2-3%) corresponds to the time the login process is terminated and the desktop is displayed. De-activating the four gnome-shell extensions (Alternative Status Menu, Quit Button, Remove Accessibility, system-monitor) that I have installed does not have any effect on session start up time. Login to Gnome classic does not show the slow session start. The system logs do not show anything suspicious. Thus, what is the best way to identify the underlying problem?

• Languages and tools that are "portable" (work well from a USB storage drive) [closed]

  - by CodexArcanum

  I'm a huge fan of running programs from my portable hard drive: it means I always have my favorite tools no matter what computer I'm on. Sadly, development tools seem to be hard to get portable at times. I recently realized that the "portable" version of MinGW I was using off my USB drive was actually interfering with a locally installed version of MinGW, so sometimes even the tools you think are portable, aren't. So what are the best portable development tools that you've used? What runs well on a portable media, leaves the host machine clean, and generally makes moving around easier for you?

• FxCop / Code Analysis with VS2010 Ultimate

  - by Cuartico

  I've getting some information about this, but I still can find a proper answer, I was asked recently in my company for this : "run a fxcop analysis on that code and tell me the results". Ok, I have VS2010 Ultimate which has code analysis, but before making any comment, I browse it on the internet cause I want to implement the best choice... So, let's say I'm gonna use the same rules on both analyzers: Should I recommend using one above the other? Should I say "hey, thats kinda old, let's use code analysis!" Should I get the same results on different computers? (for what I undersand, fxcop gives you some "points" and for what I've read, sometimes it gives you diff points on diff computers, I don't know about this with code analysis Thanks, any help would be appreciated

• Any recommended books/resources on component-based design?

  - by user1163640

  I come from a background with heavy use of the classical object-oriented paradigm for software development. The company I am a part of switched to Unity not too long ago, and we're all very excited to get started using it However, one aspect that have sparked my interested, and which I think will become a very important part of our future development, is Unity's approach to component-based design with scripting; with less focus on typical hierarchical aspect. Question I was wondering if anyone could recommend any good books on this subject? I have had trouble finding any books or books with reliable reviews, and was wondering if anyone more experienced here had something to say on the issue? Any other kind of resource would be excellent too, I'm just interested in getting to learn everything I can about it. This is not meant as a discussion about best books or resources on the topic, but simply a question regarding any resources that any of you find useful. Thank you all for your time!

• Two users sharing the same computer

  - by Pitto

  I need to share my pc with a friend of mine living in India. His pc is a p4 and he needs a bit of horsepower for calculation. Since I have an i5 I thought to let him vnc and use it but this would not allow me to use the computer at the same time. Is there a way to use the computer at the same time with different users? I've read Xorg is able to do this but I am not sure is the best solution nor I can implement it. We have Ubuntu 12.04 64bit on the i5 side and Ubuntu 12.04 32bit on the p4 side. Thank you for your kind help.

• What do Embedded Software Developers do on a day to day basis?

  - by afree100

  Edit: I am not asking how to program embedded systems. I am asking how it is done in a practical business setting. I have searched for hours for information on what software developers actually do. More specifically, what coding challenges would one experience daily (e.g. code examples (although obviously not too large), specifics)? I am interested in Linux based embedded systems mainly, but any software development would be helpful (in the C/C++/Assembly areas). Also, regarding this, a distinction between junior, intermediate and senior developers would be helpful. Also, what is the best place to prepare for such things before getting a job for the first time?

• Domain Model and Querying

  - by Tyrsius

  I am new to DDD, having worked only in Transaction-Script apps with an anemic model, or just Big Balls of Mud, so please forgive any terminology I abuse. I am trying to understand the proper separation between the domain model and the repository. What is the proper way to construct a domain object that is coming from a database, assuming the (incredibly simplified) need to query for objects by status (returns enumerable), or by ID. Should a factory be building the objects, exposing methods for GetByStatus() and GetByID(), using a DIed repository? Should a repository be called directly, knowing how to build a domain model from the DTO? Should the domain model have a constructor for get by ID, using a DIed repoistory to load the initial state, using some other (?) method for the list? I am not really sure what the best way would be, and this question has an answer advocating each one (these are certainly mutuallu exclusive).

• What is needed to become a skillful and professional software developer ?

  - by silentbang

  I am interested in studying algorithms and my strong points are problem-solving and logical thinking. However what I am guided toward is web-developing languages, SQL and they seem to not exploit the best out of me. I think it's because lots of people can learn these things easily, even steal ideas and copy code. Is that wrong? I was told that "learning algorithms is just for optimization, so you just need to know it (not a deep understanding)", but I think algorithms are my savior; it differentiates one man's abilities from others'. Also I'm learning C++ to benefit my future career. Many people say that web developer is a future trend, which worries me. I don't know what I need to standout in my career, and should I balance between web and software developing or just one? Should I work hard on algorithms?

• Learning PHP MySQL [closed]

  - by Keith Groben

  I've been a designer for several year now. I'm now very interested in learning PHP, MySQL. I've read through W3Schools already and it helped me become familiar. I now want to know where I could go to start building some simple database and php applications so I could be come familiar with coding and start to improve. I think hands on application is the best way to learn. Since I'm a beginner, much of what I've found so far is sort of advanced to me.

• What are the Search engine affects of registering the same domain on multiple top level domains (ie. .com, .ie, .nl etc.)?

  - by user1020317

  I'm looking to register a few more domains for my company, I have my-company.com at the moment, but now require my-company.com.au and my-company.nl and some others.. I'm running through my options and wondering what is the best.. Duplicate all the content on the .com package and make a replica at the other domains Buy the other domains but do a 301 redirect back to the .com domain. Create a full new website with different content for the new domains, thus having no text duplication We currently sell over the world so would like to raise our Search rankings in various countries, can this be done by buying the domain in the country, and if so, how will the above methods affect our search rankings. Any other suggestions are welcome!

• Ubuntu display - no existent

  - by Patrick M

  My HP Pavillion Dv5 1004nr worked great with Ubuntu up until 11.04. Now, ever since Unity desktop environment the display has been sporadic at best. I was told that the video driver bugs (known and largely ignored) were fixed for the ATI raedon card in my laptop with 13.04. So I installed it. 13.04 doesn't even detect the display. Boots to black screen every time now. Is there ever going to be a fix for the AMD architecture with ATI raedon chipsets? do the developers even care? this has been an issue for years, and no sign of a fix in sight....

• Jumping around to work on different features when you get stuck, is it a source of project failures?

  - by codecompleting

  On personal projects (or work), if one gets stuck on a problem, or waiting to figure out a solution to the problem, if you jump to another section of your code, don't you think it will be a good reason your application will be buggy or worse yet never get completed? Assuming you are not using git and code each feature to a specific branch, things can get out of hand since you have 3 different features you are working on, and you have unresolved issues in each. So when you get done to work, you get stressed out because you have these hanging issues and half-baked code lingering about. What's the best way to avoid this problem? (if you have it) I'm guessing using something like git and creating a branch per feature is the safest way to avoid this bad habit. Any other suggestions?

• TechEd 2014 Day 4

  - by John Paul Cook

  Many people visiting the SQL Server booth wanted to know how to improve performance. With so much attention being given to COLUMNSTORE and in-memory tables and stored procedures, it is easy to overlook how important tempdb is to performance. Speeding up tempdb I/O improves performance. The best way to do this is to not do the I/O in the first place. With SQL Server 2014, tempdb page management is smarter. Pages are more likely to be released before being unnecessarily flushed to disk. Read more about...(read more)

• How do I find out which driver a piece of hardware is using?

  - by Oli

  Today I'm trying to figure out which driver is best for my USB wireless dongle. Everywhere I look I just see Ralink STA but this isn't telling me which module this actually is. I'm sure there's a way of looking it up but the computer should be able to tell me, shouldn't it? Meta: This question is open to any piece of hardware, not just my wireless card. It would be helpful if we had a thread of useful diagnostic procedures so that other people can find out what's going on with their hardware.

• SharePoint Conference 2012&ndash;How To Find Me

  - by MOSSLover

  Hey guys I will be at the conference if you don’t follow me on twitter and you want to find me.  Look around the Women in SharePoint area in the Community Lounge.  If you don’t find me at the Community Lounge then I would say try to look at the Planet Technologies booth for me.  If you don’t find me in that booth then try Booth #22 the SharePoint Pavilion.  If I’m not in any of these places I’m either in a session, sleeping, running, or wearing a cloaking device.  You can ask me all kinds of questions about Planet, Women in SharePoint, and such.  I can try to answer the questions as best I can or direct you to someone smarter.  See you all at SPC 12!

• Improving FAQ SEO with multiple pages?

  - by asdfasdf

  I have a client who has over 200 Question/Answer style content blocks. Neither the questions or answers are very long and most of them have almost the same question but with a word or two differentiating themselves from the rest of the questions. Would SEO be helped or hurt if I would to put each QA on its own page with the title of the page the question being asked etc... Or, would that be considered "farming"? If not, what would be the best way (in SEO world) do present all these QAs? Thanks for any advice..

• Yet another Java EE 6 book

  - by alexismp

  We have a new Java EE 6 book in store! This one from Packt Publishing is called "Java EE 6 Development with NetBeans 7" by David Heffelfinger who is also author of Java EE 5 and GlassFish books. This book holds a step-by-step book documention all of the Java EE 6 features and APIs (including CDI) using the IDE with the best Java EE out-of-the-box experience : NetBeans 7. It uses GlassFish as the default container and PrimeFaces as a JSF component suite. We've covered several Java EE and GlassFish books before and I can't help but think that given writing books never helped authors retire early, having so many good books on Java EE 6 says something about its success among developers.

• Hiring developers - listing IDE as a requirement?

  - by suslik

  I've been looking at some job postings and noticed that a fair amount of them list IDEs under the 'required skills' section, even for senior positions. This is not localized to one company either, but rather it's something that comes up once in every few postings. I am perplexed by this job requirement, as my mentors and some of the best coders I've seen in my life were VIM/Emacs ninjas. Similarly, when I work with people I don't much care what tools they use as long as they are productive on the team. Can someone please explain the rationale behind hiring managers making IDEs an official job requirement?

• How to reverse engineer the SEO on a website?

  - by Startup Crazy

  I have read this question. My question is a bit different from it. I want to know how can I reverse engineer another website that is ranking the best for some keywords. For example some website called www.bla.com is there and it ranks high for many keywords and I want to learn from it how can my website be of the same authority and get the same ranking (or probably better ranking if I found something that they are missing). Can anyone enlist it as a procedure, how to reverse engineer a website?

• Release roadmap with scrum

  - by SyBer

  I need to prepare an internal product release road-map for product being built via scrum methodology, and have some difficulty correlating sprints to the road-map. The main problem is that as I don't have effort estimations for every story, because these prepared immediately before each sprint, so I don't know what will make into which sprint. I'm fine with changing the road-map as the development goes on, but need it to give at least some indication when things planned to be released. So what would be the best way to do this, other then guestimating the whole backlog? Thanks for any idea.
