  • How to speak to a computer

    - by SalemSeven
    I am a self taught.. NEW..programmer. The language I chose was Objective-C so I can write for Apple products. I have learned the hard way that Objective-C has a steep learning curve but have forced myself to look at it over and over until I get it. I feel I am completing one major step and that is becoming very comfortable with the syntax and now as I enter the next big step...finding out what is possible with a computer language - I am thinking that all software is just developed within the confines of classes-loops-booleans-IF/OR statements-variables-etc. Is that a true assessment? When thinking of software in my head do I just need to learn to convert it all to arrays-loops/variables/classes - IF/OR statements - etc? Sorry if this question sounds funny but I am just learning how to take the language in my head and talk (what I think is) the language of a computer. Is there a good book or tutorial that helps illustrate how to speak computer speak?

  • XBMC is slow and sluggish in Ubuntu 13.04; how can I speed it up?

    - by Dreamdealer
    I have a Zotac ZBOX ID84 with Intel D2550 proc and Nvidia GT520M GPU, 2GB memory and 320GB hard disk. I tried XBMCbuntu first and it ran perfectly for a few months until I started to mess around with the Terminal. After a re-install I could get the HDMI sound to work again so I installed the latest version of Ubuntu (13.04) instead. That worked fine. The sound and everything worked right away, but the interface of Ubuntu is sluggish and XBMC doesn't run as good as it did in XBMCbuntu. The video playback is slow and it stutters. It speeds up and slows down with the complexity of the video. So, the PC is more than capable to run XBMC and play the videos, but something in Ubuntu (GUI?) slows it down to an unusable pace. Can anybody tell me what I can do to speed things up? Since I'm new to Ubuntu I have no clue where to start looking.

  • Building a website, wondering how to add news to it? Details inside. [closed]

    - by Robolisk
    On the home page of my website, I'd like to add a "news" kind section, where I can add blogs and such. Now from my understanding if this was all done in hard coding I'd have to go into the code just to add stuff to it. I've looked at things like drupal and I get how those work, but I how would I be able to add this to my site? The same kind of concept? Also, one more thing, what does inc operating php into a website offer? like better looks or general preformence? I don't understand this. Excuse my grammar/spelling. (: And thank you for taking the time to read this.

  • Theme sometimes fails to load on some UI elements

    - by Neil
    I have no idea if this error as been seen before or not, I have looked around and found people saying they have errors that sound the same but none of the fixes work, my issue is that sometimes the theme does not load some parts of the UI, (the buttons and icons in this case) but the rest is just fine (window bars e.t.c) so I have no idea what the issue is, it works just fine for the most part but sometimes has this bug, if you restart the system it tends to fix it for some time so its hard to see how it could be a graphic card error, however I am very new to linux systems so I may be missing someting very fundamental here. Thank-you in advance. This image shows my problem

  • Why is using an external USB drive or USB printer causing my system to hang?

    - by thepd
    I am having some troubles using various external hard drives and my printer, all of which I connect using USB. The majority of the time, when I connect either of these devices, my system freezes up completely after about 10 minutes. They work just fine prior to that moment. I've also not noticed any problems using a USB mouse. I'm running Ubuntu 10.10 and have tried using a newer kernel (a 2.6.36 Maverick kernel from the kernel ppa, as opposed to the default 2.6.35 one) to no avail. I'm using a Dell Studio XPS 16 (M1647) which is a sort of newish laptop and so my guess is this is probably some kind of driver bug. Is there anyway to debug these sorts of issues? I've looked through some of my logs (/var/log/messages seemed the most useful) but haven't been able to find any kind of USB related logging nor anything interesting happening prior to the hang.

  • Why is Prolog associated with Natural Language Processing?

    - by kyphos
    I have recently started learning about NLP with python, and NLP seems to be based mostly on statistics/machine-learning. What does a logic programming language bring to the table with respect to NLP? Is the declarative nature of prolog used to define grammars? Is it used to define associations between words? That is, somehow mine logical relationships between words (this I imagine would be pretty hard to do)? Any examples of what prolog uniquely brings to NLP would be highly appreciated.

  • Problems after installing Ubuntu LiveUSB on my 2nd HD

    - by user113106
    I decided to create a Ubuntu USB installer using the Universal USB Installer, selecting a Ubuntu 12.10 ISO. I selected my D: drive, my NON-windows7 carrying drive as install. After this I Re-booted my system and my PC began to Run the Ubuntu Boot-startscreen every time I power up the machine, giving errors like this: Root=Unknown I used my girlfriend's laptop to create, on the exact same way, a real! USB Ubuntu installer. Booting from that USB, picking the option Run Ubuntu from this USB I get the following error: http://postimage.org/image/63qkv98c1/ Let's try installing it from that USB to a Hard-Disk: http://postimage.org/image/usqbwymfx/ As I said: I do not have the Option to pick my Boot-section, at this very moment I can only access to the Ubuntu installation and nothing else. I've read about 90% of other Questions that could've been related, but I could not find a solution. BTW I'm running a Acer Aspire 2Quadcore 4gb DDR 2 Ati Radeon HD, 64bit and I've set my Bios OS-usage from Windows to "Others"

  • How are USB ports related to the computer power, and why would they cause my computer to freeze?

    - by BDuelz
    I have an issue with my new Toshiba laptop. Whenever I plug in an external USB device, if the laptop is not plugged in to the wall, the laptop freezes. However, nothing happens if the laptop is plugged in to the wall. When I say the laptop freezes, I mean it really freezes. The only way to recover is to hard reboot. My question is, what could be causing this? Could it be the extra power drain from the sub devices that causes this (even the simplest flash drives cause a freeze)? Please help me out, it's very annoying. Thanks

  • Is Java a good choice for cross-platform games?

    - by CommunistPancake
    I'm looking to create a game in Java and would like it to work on Windows, Linux, and Mac. I'm pretty sure C# is a bad choice for this, and I don't have enough experience in C or C++. I want to stay away from Flash. Therefore, Is Java a good choice for me? Mostly, I use C#, and think that Java is similar, so I assume it won't be that hard to learn. But is it fast enough? Is there a language more suited for my needs than Java?

  • Advice on triple/quadruple-booting?

    - by professorfish
    I am currently running Windows 7 Home Premium x64 on my laptop. I would like to install more than one Linux distro, IN ADDITION TO Windows 7. How do I go about this, what do I need to be careful and aware of, is it possible? The specific distros I might eventually install: Definitely: Ubuntu (is it a good idea to install the Linux-Secure-Remix version?) Almost definitely: OpenSUSE Probably: Zorin Possibly: Arch Possibly: Fedora Possibly: FreeBSD Computer details: Successfully used WUBI for Ubuntu in the past Recently reinstalled Windows using the RECOVERY partition Windows 7 Home Premium x64 model: ASUS K53U series AMD Brazos Dual Core E450 1.65 GHz 750GB hard drive, currently partitioned into C: (300GB total, 246 GB free), D: (373GB - total, 167 GB free), and RECOVERY (the rest of the space, I think) 4GB RAM Can I be sure that GRUB will work, if WUBI has worked? In short, how do I go about triple- or quadruple-booting Windows 7, Ubuntu and other distros? What do I need to be aware of? How do I set up the partition structure? Thank you in advance

  • How to learn an API

    - by inovaovao
    When I find some interesting project (e.g. on GitHub) I often would like to use it and try it out to see how it works, but if there isn't a good documentation or some kind of tutorial it's hard to figure out how to use it. So my question is: how do you approach such a situation? How do you figure out which classes are important and how to chain them to put them to use? What would you look at first? An advice I found is to look at the tests (if there are any). But if there are unit tests for every class, how do you know which ones to look at first?

  • Repositories and the Save Method

    One of the questions I've been getting lately goes like this: Should a Repository class have a Save method? And the standard answer: It depends. It's hard to keep track of all the different approaches to implementing the repository pattern these days, but I assume when someone asks me this type of question they are thinking of using code like this: var employee = new Employee(); employeeRepository.Save(employee); var account = new Account(); accountRepository.Save(account); This...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How do I avoid the complexity concerns of frameworks while keeping my team marketable?

    - by Desolate Planet
    When deciding upon how to design a software project with my colleagues, most suggestions tend to be for using specific frameworks "because it's popular in the job market" or "that's the framework that gets recruiters on the phone," and never what I'm looking for which is, "because it's a good fit for the project as it makes the system more adaptive to future changes and makes life easier for developers." I didn't start looking at projects in this way until I started reading up on domain-driven design. I've found that the actual domain is hidden deep under the frameworks used and it's hard to learn the business processes that have been implemented by the software product. Is there a way to marry the two competing goals: getting exposure as a development team while still being able to avoid complexity? Are frameworks that compromise, or are there other solutions out there?

  • Image caching when rendering the same images on different pages

    - by HelpNeeder
    I'm told to think about caching of images that will be displayed on the page. The images will be repeated throughout the website on different pages and I'm told to figure out the best way to cache these images. There could be few to dozen of images on single page. Here's few questions: Will browser caching work to display the same images across different web pages? Should I rather store images in stringified form in a memory instead, using JavaScript arrays? Store them on hard drive using 'localStorage'? What would be easiest yet best option for this? Are there any other alternatives? How to force cache? Any other information would be greatly appreciated...

  • Missing & Failed Folder At/and After Installation

    - by user170558
    I am new to Linux, and I've trying to install Ubuntu 12.04 LTS (dual boot with Windows XP). I choose to add new partition (FAT32 150 GB) for the shared folder. But when I pressed the install button, the installer warned me : Failed to create the 150 GB shared partition. So I turned back to the partition section and changed the shared partition to 50GB FAT32 (/mnt/shared). I pressed the install button and I was successful. But, when I boot Ubuntu, I could not find this 50GB folder. QUESTIONS: 1. What is wrong with the 150GB size? Is my hard disk failing? 2. Why is the 50GB shared folder not showing? Thank for the help.

Here is a screencap that shows my problem. The problem occurs in Firefox and Chrome the same way, and on the same websites. Thanks for your help. Best regards el

    Recently I installed Picasa in my Ubuntu 14.04 using Wine. After performing a Wine configuration I was able to access all the images in the NTFS partitions on my hard disk. I performed Wine configuration as said in Why can an application installed using Wine not access NTFS partitions?. After 3 days, it became unable to access 2 NTFS partitions. But I can access 1 NTFS partition(named E, see image below). As you can see in the screenshot, I am unable to expand both D and F. How can I fix this issue permanently ?

  • Can I virtualize a pre-installed Windows 7?

    - by SpashHit
    I am considering buying a new computer with Windows 7 (64-bit) pre-installed. Would it be possible to install Ubuntu (preferably 64-bit) dual-boot on such a machine, and then, using VirtualBox / VMWare, etc. under Ubuntu, make a virtual machine that "points to" the existing Windows 7 OS (without making a copy of it)? Just to be clear... at the end of this process: I would have a machine that dual-booted both Windows 7 (64-bit) and Ubuntu (64-bit). If I choose to boot Ubuntu, I would then have the possibility of running a visualization of Windows 7 within Ubuntu. There would only be 1 copy of Windows 7 on the hard disk.

  • Failing to install Ubuntu 13.04

    - by Kayven Riese
    I have a new Windows 8 Sony Vaio SVF14A15CXB laptop that has UEFI and I have been struggling through an Ubuntu installation. I have a bootable Ubuntu DVD+R and I have managed to mess with my BIOS/UEFI so that it boots. I have used Windows 8 to create a desired hard disk partition and installed Ubuntu there, and have burned a boot-repair http://sourceforge.net/p/boot-repair-cd/home/Home/ and rEFInd http://www.rodsbooks.com/refind/getting.html disk and neither will boot. I know I should continue googling and struggling, but I am getting frustrated. Thanks to anyone who gives me the time of day.
