  • Ubuntu only boots with USB plugged in

    - by Ben
    I'm new to the Linux world so please bear with me! :-) I installed Ubuntu via USB drive onto my hard drive. If I boot the PC without the usb drive I used, Ubuntu will not load. After booting I can unplug without any consequences. I looked on the hard drive and there is a boot folder. On the USB drive, this is the tree contents: /media/disk$ tree . |-- adtext.cfg |-- boot.cat |-- f10.txt |-- f1.txt |-- f2.txt |-- f3.txt |-- f4.txt |-- f5.txt |-- f6.txt |-- f7.txt |-- f8.txt |-- f9.txt |-- initrd.gz |-- isolinux.bin |-- isolinux.cfg |-- ldlinux.sys |-- linux |-- menu.c32 |-- menu.cfg |-- po4a.cfg |-- prompt.cfg |-- splash.png |-- stdmenu.cfg |-- syslinux.cfg |-- text.cfg |-- ubnfilel.txt |-- ubnpathl.txt `-- vesamenu.c32 Am I correct in my assumption that the boot aspect is associated to the USB drive? If so, how do I get it to boot without the USB? I'm guessing copying into some location and modifying grub?

  • Usng Rails ActiveRecord relationships

    - by Brian Goff
    I'm a newbie programmer, been doing shell scripting for years but have recently taken on OOP programming using Ruby and am creating a Rails application. I'm having a hard time getting my head wrapped around how to use my defined model relationships. I've tried searching Google, but all I can come up with are basically cheat sheets for what has_many, belongs_to, etc all mean. This stuff is easy to define & understand, especially since I've done a lot of work directly with SQL. What I don't understand is how to actually used those defined relationships. In my case I have 3 models: Locations Hosts Services Relationships (not actual code, just for shortening it): Services belongs_to :hosts Hosts has_many :services belongs_to :locations Locations has_many :hosts In this case I want to be able to display a column from Locations while working with Services. In SQL this is a simple join, but I want to do it the Rails/Ruby way, and also not use SQL in my code or redefine my joins.

  • How is GroupOn website programmed?

    - by Maxi Garcia
    Hello world! This is my first time on Stackoverflow.com and it's great to be here! I need some expert programmer out there to tell me how the GroupOn's platform operates, from the programming point of view. Which are the most complex features it has and what technology do they use? If I were about to start learning programming languages, what should I learn to create a site like GroupOn.com? Is there any website where I can learn the basic principles for free? I appreciate your advices. Thanks in advance!

  • Writing Android apps in C#

    - by JamesBrownIsDead
    I'm a C# programmer and want to write an Android app. I'm a stubborn curmudgeon and refuse to write Java ever again (after switching to C# six years ago). Besides Mono and MonoDroid (and writing Java), are there any options for me? Or should I just feel foolish for refusing to returning to my Java roots? (Please refrain from Java-related vs. C# discussion. I was being rhetorical when I asked about returning to me Java roots.)

  • Running multiple image manipulations in parallel causing OutOfMemory exception

    - by Tom
    I am working on a site where I need to be able to split and image around 4000x6000 into 4 parts (amongst many other tasks) and I need this to be as quick as possible for multiple users. My current code for doing this is var bitmaps = new RenderTargetBitmap[elements.Length]; using (var stream = blobService.Stream(key)) { BitmapImage bi = new BitmapImage(); bi.BeginInit(); bi.StreamSource = stream; bi.EndInit(); for (var i = 0; i < elements.Length; i++) { var element = elements[i]; TransformGroup transformGroup = new TransformGroup(); TranslateTransform translateTransform = new TranslateTransform(); translateTransform.X = -element.Left; translateTransform.Y = -element.Top; transformGroup.Children.Add(translateTransform); DrawingVisual vis = new DrawingVisual(); DrawingContext cont = vis.RenderOpen(); cont.PushTransform(transformGroup); cont.DrawImage(bi, new Rect(new Size(bi.PixelWidth, bi.PixelHeight))); cont.Close(); RenderTargetBitmap rtb = new RenderTargetBitmap(element.Width, element.Height, 96d, 96d, PixelFormats.Default); rtb.Render(vis); bitmaps[i] = rtb; } } for (var i = 0; i < bitmaps.Length; i++) { using (MemoryStream ms = new MemoryStream()) { PngBitmapEncoder encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(bitmaps[i])); encoder.Save(ms); var regionKey = WebPath.Variant(key, elements[i].Id); saveBlobService.Save("image/png", regionKey, ms); } } I am running multiple threads which take jobs off a queue. I am finding that if this part of code is hit by 4 threads at once I get an OutOfMemory exception. I can stop this happening by wrapping all the code above in a lock(obj) but this isn't ideal. I have tried wrapping just the first using block (where the file is read from disk and split) but I still get the out of memory exceptions (this part of the code executes quite quickly). I this normal considering the amount of memory this should be taking up? Are there any optimisations I could make? Can I increase the memory available? UPDATE: My new code as per Moozhe's help public static void GenerateRegions(this IBlobService blobService, string key, Element[] elements) { using (var stream = blobService.Stream(key)) { foreach (var element in elements) { stream.Position = 0; BitmapImage bi = new BitmapImage(); bi.BeginInit(); bi.SourceRect = new Int32Rect(element.Left, element.Top, element.Width, element.Height); bi.StreamSource = stream; bi.EndInit(); DrawingVisual vis = new DrawingVisual(); DrawingContext cont = vis.RenderOpen(); cont.DrawImage(bi, new Rect(new Size(element.Width, element.Height))); cont.Close(); RenderTargetBitmap rtb = new RenderTargetBitmap(element.Width, element.Height, 96d, 96d, PixelFormats.Default); rtb.Render(vis); using (MemoryStream ms = new MemoryStream()) { PngBitmapEncoder encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(rtb)); encoder.Save(ms); var regionKey = WebPath.Variant(key, element.Id); blobService.Save("image/png", regionKey, ms); } } } }

  • What way to use the CGContext to draw is suitable?

    - by Tattat
    I know that the CGContext cannot call it to draw directly, and it needs to fill the drawing logic in the drawInContext, and call the CGContext to draw using "setNeedsDisplay", so, I designed a cmd to execute, but it cause some problems... like this : http://stackoverflow.com/questions/2617827/why-i-cant-draw-in-a-loop-using-uiview-in-iphone I think the CGContext is very different from my previous programming experience....(I used HTML5 canvas, that allow me add more details, after I draw, so do the Java Swing) Actually, I want to know what is the suitable to implement these kind of thing in Apples' programmer mind.

  • Nginx location issue

    - by dave
    I'm trying to set a longer (30 day) 'expires' header for my (images only) in the /misc-stuff/ directory. This is what I'm using for my site : # Serve static files directly from nginx location ~* \.(jpg|jpeg|gif|png|bmp|ico|pdf|flv|swf|exe|html|htm|txt|css|js) { add_header Cache-Control public; add_header Cache-Control must-revalidate; expires 7d; } I want to be able to keep that code in to handle regular site images, but create a new block to handle the /misc-stuff/ directory. I have tried : location ^~ /misc-stuff/ { ... } The problem I'm having now is that my backup .php files in that directory show up as plain text if someone tries to access it. How do I set it up so ONLY .gif images in the /misc-stuff/ directory are effected?

  • Programmatically modifying an embedded resource before registering/referencing it on the page

    - by Jimock
    Hi All, Firstly, "Modifying" may be the wrong term, I see a few people have posted online just asking whether they can actually modify an embedded resource. What I am wanting to to, is use a resource in my assembly as a kind of template which I would do a find and replace on before registering it on the page - is this possible? For example; say I have a few lines of jQuery as an embedded resource in my assembly and in this script I am referencing a CSS class name that can be set by the front-end programmer. Since I do not know what the CSS class will be until implementation, is there a way of going through the embedded resource and replacing, say, $myclass$ with ThisClassName. Any help would be appreciated, if it's not possible then at least tell me so I can stop chasing my tail. Cheers, James

  • built in "Offer Remote Assistance" not working because of permissions

    - by Caleb_S
    I'm trying to enable permissions for a user on a Windows7 machine to use the built in feature called "Offer Remote Assistance" or "Windows Remote Assistance". This feature works fine if the user is added to the "domain admins" security group, but for security reasons, I cannot leave him in that group. This is within a SBS2003 Domain. I have added the user and also a group that he is apart of to the Small Business Server Remote Assistance Policy, after following some documentation I was able to find, but this has not worked. Can you tell me how to enable this feature for this user and or a user group? http://content.screencast.com/users/CASEIT/folders/Forum%20Pictures/media/2a518bc9-4184-4520-8b76-cdf46555f568/2011-08-18_1330.png

  • Which programming languages have helped you to understand programming better?

    - by Xaisoft
    Which programming languages not only make you more proficient in the particular language your are learning, but also have a direct impact on the way you think and understand programming in general; therefore, making you a better programmer in other languages. Basically, which languages have the biggest impact on understanding the how and why of different programming concepts? What about Scheme? I have heard good things about that. I thought about taking the simplest of problems and implementing them in various languages. Has anyone done this?

  • How do the young start programming nowadays

    - by PP
    Back in the late 80s/early 90s I learned GWBasic on MS-DOS. Then Turbo Pascal. Then Turbo C/Asm. Later I stumbled into PHP and finally made a career out of Perl programming. I'm curious how actual under-25s found their way into programming. There is a lot of discussion about what path you would steer your children if you wanted them to learn programming, but I would like to hear from the newer generation to find out their more modern experiences about becoming a programmer. Note: no stories from people who first discovered programming at university.

  • CentOS - PHP - Yum Install with Custom ./configure params

    - by Mike Purcell
    I have successfully configured and compiled php on my dev server, and works great, but after talking to a sysadmin buddy, he informed that custom compiles of the latest builds are not recommended for production (or even development) systems. He noted a situation where they custom configured and compiled PHP 5.3.6, only to find that there was some issue with a low-level Postgres driver, so they had to revert back to 5.3.3. So I am considering going back to yum to install PHP, however I have several custom configuration settings and was wondering if it's possible to pass or configure how PHP will be compiled through YUM? My current configure line: Configure Command => './configure' '--with-libdir=lib64' '--prefix=/usr/local/_custom/app/php' '--with-config-file-path=/usr/local/_custom/app/php/etc' '--with-config-file-scan-dir=/usr/local/_custom/app/php/etc/modules' '--disable-all' '--with-apxs2=/usr/sbin/apxs' '--with-curl=/usr/sbin/curl' '--with-gd' '--with-iconv' '--with-jpeg-dir=/usr/lib' '--with-mcrypt=/usr/bin' '--with-pcre-regex' '--with-pdo-mysql=mysqlnd' '--with-png-dir=/usr/lib' '--with-zlib' '--enable-ctype' '--enable-dom' '--enable-hash' '--enable-json' '--enable-libxml' '--enable-mbstring' '--enable-mbregex' '--enable-pdo' '--enable-session' '--enable-simplexml' '--enable-xml' '--enable-xmlreader' '--enable-xmlwriter'

  • Practical guide to programming paradigms ?

    - by Pierre
    I think I might be misunderstanding the whole thing and I am looking for some programming wisdom. When faced with a programming challenge, I feel the most important question is "which programming paradigm(s) are better suited to handle it, and how to apply them". A distant second is "which language to use". Yet it seems that most of the programming related content I stumble upon on the Internet has it exactly backwards and focuses mostly on the language choice. An object-oriented solution is fundamentaly the same, whether it's implemented in c++, Java or PHP... So where is the paradigm centered content? Where is the "practical guide to programming paradigms and implementations" and other literature helping bringing real-world and programming concepts together? Note: I already know about "Programming Paradigms for Dummies: What Every Programmer Should Know" from Peter Van Roy.

  • vector quality of svg and pdf

    - by Kasper
    I'm converting pdf files to svg as it is easier to use svg files on webpages. I first thought the quality of svg must be similar to pdf, as they are both vector graphics. However, now I look a little better on it, it seems that pdf is a bit superior: (https://dl.dropboxusercontent.com/u/58922976/Photos/1.png) I wonder if I could change this in some way. Is this because pdf vectors are just better quality ? Or is this because chrome renders svg in lower quality than adobe reader renders pdf ? Is this a setting in the svg file that I could change ? Here is the pdf file: https://dl.dropboxusercontent.com/u/58922976/syllabusLinAlg2012.59.pdf And here is the svg file: (https://dl.dropboxusercontent.com/u/58922976/syllabusLinAlg2012.59.svg) I've made this svg file in illustrator, and only chrome is able to use the embedded svg fonts. So firefox and internet explorer won't give the expected result.

  • Uploading files to https mediawiki

    - by zac
    I am unable to upload files (images) to my mediawiki install. I think it may have something to do with it is being hosted as http secure(HTTPS). I followed carefully the instructions here. I updated write permissions to the /images/ dir drwxrwxrwx 2 apache apache 4096 Apr 13 19:04 images php.ini file_uploads = On In LocalSettings.php $wgEnableUploads = true; $wgFileExtensions = array('png','jpg','jpeg','gif'); When I try to upload it quickly refreshes the page without any errors or any indication anything went wrong, other than how fast it refreshed. When I navigate to the history of uploads it is empty. How can I troubleshoot this. Is it related to the secure http?

  • htaccess rewrite and auth conflict

    - by Michael
    I have 2 directories each with a .htaccess file: html/.htaccess - There is a rewrite in this file to send almost everything to url.php RewriteCond %{REQUEST_URI} !(exported/?|\.(php|gif|jpe?g|png|css|js|pdf|doc|xml|ico))$ RewriteRule (.*)$ /url.php [L] and html/exported/.htaccess AuthType Basic AuthName "exported" AuthUserFile "/home/siteuser/.htpasswd" require valid-user If I remove html/exported/.htaccess the rewriting works fine and the exported directory can be access. If I remove html/.htaccess the authentication works fine. However when I have both .htaccess files exported/ is being rewritten to /url.php. Any ideas how I can prevent it?

  • Why not to use Array of errors instead of Exception Handling !?

    - by Naughty.Coder
    Why not using array of errors instead of throwing errors and check if it's not empty later in the code.... Exception handling is very confusing to me , I can not understand it's purpose ... can anybody enlighten me !? they compare it with die() as better not to stop the execution of the code , why would I stop the execution of code if I don't want to !? ofcourse I do I'm a beginner programmer , it might be confusing to you as well , or because i'm not very experienced in this ugly thing. Please in the context of PHP only.

  • Common Ruby Idioms

    - by DanSingerman
    One thing I love about ruby is that mostly it is a very readable language (which is great for self-documenting code) However, inspired by this question: http://stackoverflow.com/questions/609612/ruby-code-explained and the description of how ||= works in ruby, I was thinking about the ruby idioms I don't use, as frankly, I don't fully grok them. So my question is, similar to the example from the referenced question, what common, but not obvious, ruby idioms do I need to be aware of to be a truly proficient ruby programmer? By the way, from the referenced question a ||= b is equivalent to if a == nil || a == false a = b end (Thanks to Ian Terrell for the correction) Edit: It turns out this point is not totally uncontroversial. The correct expansion is in fact (a || (a = (b))) See these links for why: http://DABlog.RubyPAL.Com/2008/3/25/a-short-circuit-edge-case/ http://DABlog.RubyPAL.Com/2008/3/26/short-circuit-post-correction/ http://ProcNew.Com/ruby-short-circuit-edge-case-response.html Thanks to Jörg W Mittag for pointing this out.

  • GIMP: change the exact color on the image - OK, but transparency disappears

    - by Haradzieniec
    There is no problem for me now to change color for pixels of the same color: I click on "Select by Color Tool"(Ctrl+O). The pixels of the same color are selected now. Then I press Ctrl+,. The selected pixels are white now (the white color is taken from a foreground color). The problem is the transparency. The green color I want to change to the white one has transparency. Once I use my method, the transparency disappears so all my-green-color with any transparency becomes white and without transparency. How do I keep the transparency by using my method? My picture is in .png format.

How do I make --color=auto a default ls argument?

I don't believe anything contained within it is relevant to this question. I also want to add that I want the zip files to be a forced download.

  • Is it a bad idea if equals(null) throws NullPointerException instead?

    - by polygenelubricants
    The contract of equals with regards to null, is as follows: For any non-null reference value x, x.equals(null) should return false. This is rather peculiar, because if o1 != null and o2 == null, then we have: o1.equals(o2) // returns false o2.equals(o1) // throws NullPointerException The fact that o2.equals(o1) throws NullPointerException is a good thing, because it alerts us of programmer error. And yet, that error would not be catched if for various reasons we just switched it around to o1.equals(o2), which would just "silently fail" instead. So the questions are: Why is it a good idea that o1.equals(o2) should return false instead of throwing NullPointerException? Would it be a bad idea if wherever possible we rewrite the contract so that anyObject.equals(null) always throw NullPointerException instead?
