• 12.04 Booting into Terminal

  - by user170796

  To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.

• What is the the best way to become an iPhone developer?

  - by Noah89

  I have no experience as a programmer but I'd like to become a iPhone developer. Some people tell me to learn java because it is a Object Oriented Language. Other people tell me to go with C++. However, everyone advises me to actually learn any language and learn what programming is all about before I actually develop for iPhone. Please, let me know what would be the best choice and what books would be good for a total beginner and any website that offers any good tutorials.

• What should I know before getting involved in Kinect development?

  - by chossen-addict

  I'm in the final year of my Computer Science degree, and I'm starting to look at what I can work on as a final-year project. I've been looking at creating a Kinect application, but I'm not sure if I have the necessary background to get involved in its development. What should I know before starting Kinect development? Are there areas of programming I should have a background in in order to understand what I need to do to create a Kinect app?

• Difference between Global and Local SEO

  - by user29660

  I have been reading up on SEO techniques in an effort to learn how to do it thoroughly so I can charge my client for the service. To guage my price I have checked out competitor prices and noticed that theres a fair price difference when it comes to guarenteeing a page 1 ranking with global keywords compared to local keywords. So what is the difference in terms of work load and techniques used to justify this price difference? just to clarify, i am looking for technical differences in programming , methodology etc.

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

• Is C++ still a "language"?

  - by slashmais

  Considering that C++ is a conglomerate of at least the following: C C-with-classes (original C++) templates (class, function) template meta-programming variadic templates(pdf) lambda functions preprocessor macros, pragma's each of which requiring specialized knowledge of their distinct implementation semantics. You can use only some of the above and call your code "C++". Still a language?, or else what is it?

• If I were to start an Android or iPhone app or game, what program should I use?

  - by John

  I don't really know a lot about programming and the only things I do is using codes with Gamemaker, but I have read that it is too basic and it can't be used with iPhone or Android. Is there anything free that I can use to make games for those platforms? Or if not, any suggestions for engines or anything else? I was wondering about Unity, for example, is that a good investment to use for making games?

• C++ Without Source Files

  - by Snowman

  Bjarne Stroustrup mentions in his book "The C++ Programming Language, 4th Edition" that not all C++ implementations use files to store and compile code: There are systems that do not store, compile, and present C++ programs to the programmer as sets of files. (Chapter 15, page 419) Later in the chapter, he reiterates that certain implementations do not use files but he does not give any examples. How would such an environment function compared to a more common file-based environment?

• What interface does python use to implement sockets?

  - by user2738698

  When I programmed in python, I believe I interfaced with the transport layer using sockets. If python was programmed by humans, they must have used an interface that was "lower" than sockets, to provide us with the interface to sockets. I assume firewalls, also programmed by humans, use interfaces of lower layers in the same manner, so is there a way to access such lower layers, in terms of programming?

• What would one call this architecture?

  - by Chris

  I have developed a distributed test automation system which consists of two different entities. One entity is responsible for triggering tests runs and monitoring/displaying their progress. The other is responsible for carrying out tests on that host. Both of these entities retrieve data from a central DB. Now, my first thought is that this is clearly a server-client architecture. After all, you have exactly one organizing entity and many entities that communicate with said entity. However, while the supposed clients to communicate to the server via RPC, they are not actually requesting services or information, rather they are simply reporting back test progress, in fact, once the test run has been triggered they can complete their tasks without connection to the server. The request for a service is actually made by the supposed server which triggers the clients to carry out tests. So would this still be considered a server-client architecture or is this something different?

• Taking too long to get skills for entry level programmer position [closed]

  - by greenonion

  I don't have the skills for an entry level position as a .Net programmer. I am trying to learn what I need but there is too much to learn and too little time. What can I do? About two months ago, I went to a job interview for an entry level C# .Net programming/consultant position in NYC. When I heard back from them, they told me that the knowledge gap between what I knew and what they needed me to know was too big and I might have been a better fit if I had 6 months of experience. This was the first interview that I went on since graduating college. before the interview, I read a book on visual C#. Turns out it wasn't a very good book and I was missing a lot of key areas of knowledge such as ADO.net SQL (I had learned some LINQ) A little bit about how memory is handled Multiple threaded programming, etc. Because the book wasn't very good, the stuff I did know, I didn't know very well. I felt crushed. I've applied for jobs to gain experience but when recruiters hear that I have no experience they lose interest. I figured that I can at least work on my knowledge. Since then, I read "SQL Essentials" to cover the SQL bit and I found a pretty awesome book that is good enough to clear up what's hazy in my mind and covers almost all of the extra topics. The book is "C# 4.0: The Complete Reference" by Herbert Schildt. I'm even learning a lot about the topics I was familiar with. For a month now I've been working my way through this beast of a book. However, gaining the knowledge I need is taking too long. I can't hold off not having a full-time job much longer. I'm not stupid and I'm studying constantly pouring through the book, asking questions on stackoverflow, referencing the C# specification, etc. I have made great progress but there is just too much ground to cover. I'm on chapter 12 which is about a 3rd through the book. To get an idea of what I know vs don't know, the table of contents is on amazon: http://www.amazon.com/C-4-0-The-Complete-Reference/dp/007174116X How on earth can someone know enough to function as a programmer in the real world? Can I try for a job in academia? Will I have time to finish learning the rest of the C# language or am I just un-hireable?

• A friend told me Python is garbage, I'm taking web design classes in the Spring and I have a textbook on C++. What should I do? [on hold]

  - by user107165

  I dont know if I should start digging into Python beforehand just to get acquanited with programming and "whet my appetite" or if I should work on the C++ book... Python definitely has more resources around town and I like the beginner friendly approach that seems to go along with every site that appeals to it. Or should I just wait for my assignments that start in 4 months? Any tips for an aspiring programmer?

• How to elegantly work with a lot of print functions?

  - by user1824372

  I'm working on a Python project that is executed on a terminal (or console) for which I am planning to implement a GUI. I did not major in CS so I really have no idea how to effectively design a terminal GUI such that: the user interface looks good in GUI, it is directed to a certain widget, let's say, a text label, or a bottom bar, or a hide-able frame. Do you have any suggestions? Currently, I am using the print function to provide essential information on STDOUT during execution, so a lot of print calls are distributed here and there in the code. I'm thinking of using macro-like variables such as 'FILE_NOT_EXISTS_MESSAGE' for printing, and all of them and their values would be defined in one file. Is that a standard way to do this? Should I introduce a logging system? In summary, I'm looking for a pattern for handling console output that is effective and adaptable.

• Games for software development teams? [closed]

  We have been running weekly meetings for the team in the interest of learning. I'd like to mix these up from sit and listen type exercises to something more engaging. So I'm looking for a fun games to play with a team of 10 developers. They are of ranging experience, and the games must provide some kind of insight to some fundamental concept of programming the developers tend to forget. All ideas welcome!

• What important aspects of Java should I know coming from Python?

  - by Macuser

  So, I've been browsing the job market, and it seems almost every programmer position requires either knowledge in the .NET, C#, or Java, and I'm looking to pick up Java, as I am not interesting very much with programming for Windows environments. So, what syntax differences should I look out for (except different class names), and any practices that I should avoid using in Java which is normally used in Python?

• Are Intel and Motorola moving towards a MIPS/RISC model? [closed]

  - by Nick Rosencrantz

  Is it true what I read that Intel and Motorola are moving from CISC to a programming model more like RISC/MIPS? Why? From the famous book "Computer Architecture" by Hennessay which usually is recommended around here: Recent implementations of the x86 architecture actually translate x86 instruction into simple operation that look like MIPS instuctions.... Page 335. What does this mean specifically? Can you show me an example?
