• Continuing to code on large projects

  - by user3487347

  I am a hobbyist programmer, and I've started many medium - sized projects to work on just by myself. These include games, a raytracer, physics simulations etc. By the time these projects get to a certain size (around 5000 lines), I begin to slow down in adding features to the program. This is not because of a lack of ideas of what to implement in a program, but rather a struggle in how to go about it. In particular, I'm afraid of breaking what I already have working in order to implement a new feature. I've tried using version control like Git and Subversion, but these seem unnecessary when you are a one man team. I simply have a folder of "versions" of my program, one for each major change I make. How do I keep coding past this 5000 line mark? What about the 50000 line mark?

• How can I disable update checking on boot?

  - by Chauncellor

  I'm running off of a thumb drive with very average read/write speeds and automatic update checks makes the bootup far less pleasant. Since I manually update via apt there's truly no need to notify me like on a normal desktop. In older versions of Ubuntu there was an item to disable this behavior. On 12.04 this is no longer the case. would it be the 'unattended-upgrades' item in /etc/init.d? If yes, would simply removing the init script would solve my problem?

• Is there a version control system that can show changes to a specific method or function?

  - by chesles

  Sometimes it would be nice to be able to say something like: (git|svn|hg|etc) diff Foo.c:main (git|svn|hg|etc) log log Foo.c:main to see the changes made to a specific function within a source file since the last commit, or the complete history of changes. My question is two-fold: Does something exist that does this? Would such a tool be practical? It would have to do some simple parsing of the code at each revision in order to compare different versions of the function; would the overhead be too much for it to be efficient?

• Full brightness and keyboard backligh at boot

  - by joelalmeidaptg

  I own an Asus N56VZ, and each time I start Ubuntu (13.10 and prior versions) my screen brightness and keyboard backlights reset their values to the max. Ubuntu doesn't save my settings on reboot. I was wondering if someone could help me with this? It is horrible when, at night, I turn on my computer - it is like looking directly to the sun, and it hurts my eyes. I tried googling and none of the pages I found actually helped. I think my issue might be grub-related. I have a dual-boot with Windows 8.1, so before I start my computer I see grub to choose my operating system. My screen starts at full brightness as soon as I reach grub. Maybe he is making the OS forget about my last values, overriding it with its? Does someone knows how to solve this? Thanks in advance :) PS: I'm using bumblebee with Nvidia driver 304, but this issue existed before I installed it.

• Do any database "styles" use discrete files for their tables?

  - by Brad

  I've been talking to some people at work who believe some versions of a database store their data in discrete tables. That is to say you might open up a folder and see one file for each table in the database then several other supporting files. They do not have a lot of experience with databases but I have only been working with them for a little over a half year so I am not a canonical source of info either. I've been touting the benefits of SQL Server over Access (and before this, Access over Excel. Great strides have been made :) ). But, other people were of the impression that the/one of the the benefit(s) of using SQL Server over Access was that all the data was not consolidated down into one file. Yet, SQL Server packs everything into a single .mdf file (plus the log file). My question is, is there an RDBMS which holds it's data in multiple discrete files instead of one master file? And if the answer is yes, why do it one way over the other?

• JEditorPane Code Completion (Part 3)

  - by Geertjan

  The final step is to put an object into the Lookup on key listening in each of the JEditorPanes, e.g., a "City" object for the CityEditorPane and a "Country" object for the CountryEditorPane. Then, within the CompletionProviders, only add items to the CompletionResultSet if the object of interest is in the Lookup. The result is that you can then have different code completions in different JEditorPanes, as shown below: I've also included the Tools | Options | Editor | Code Completion tab, so that the code completion can be customized. The full source code for the example is here: java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.2/misc/CustomerApp

• Ubuntu 12.04 edit grub

  - by J. R. Crocker

  I just install Ubuntu 12.04. I want to change the boot order of grub. Previous versions of grub.cfg I was able to change the permissions and the do a gedit. After reloading 12.04, I was able to change permissions for grub.cfg, but gedit will not let me save it. I am a little irritated that Ubuntu is suppose to be open source. However someone has chosen to lock one out of a file. I do realize that some people have no business doing a edit on grub. I am a long time user of Unix and Linix.

• Will there be an option in the GUI to change the week-starting day in 11.04?

  - by Roddie

  This has been problematic for me in Ubuntu since I live in the UK but want the week to start on a Sunday (because that is the system my work use). I've faffed about in the last couple of versions of Ubuntu to no avail (it changes in Evolution but not on the desktop calendar etc.) and don't want to be editing locale files. I understand it's probably an issue with GNOME so are there any plans to implement it with Unity? I find it baffling that an operating system doesn't have such a simple option that even my phones always seem to have had.

• 12.04 install now just blank screen

  - by bull

  I have attempted to install a new copy of 12.04 using usb stick instead of using download manager. Everything went fine while using usb stick until I restarted after installation was complete. Then, I got the screen with cursor and 4 lines of script with the first line saying "could not write to bytes: broken pipes". I have used several versions of Ubuntu from 6.04, but this one seems broken. I have tried nouveau.blacklist and many other suggestions to no luck. I am using hp pavilion m7790y dual core processor system, with nvidia 7600gt video card, 4gb ram and two hard drives with Vista on one and fresh install of Ubuntu 12.04 on other. I'm still looking for help to solve this problem. Thanks in advance.

• Generate Unique Abstract Backgrounds with Ablaze

  - by Jason Fitzpatrick

  If you want custom and unique backgrounds without having to code your own image-generating engine, Ablaze makes it simple (and fun) to create abstract images. You can customize a wide array of options in Ablaze including the base shape (ring, horizontal line, or random), number of particles, distance each particle travels, and the speed (if you increase the speed range you get more distinct lines and if you decrease it you get smoother smokier shapes). You can also seed the design with a color palette pulled from any image you provide (the sample above was seeded with a Wonder Woman comic panel). Tweak and reset the pattern generation as much as you want; when you create an abstract image worthy of your desktop just click the save button to grab a copy of it in PNG format.
