• Is it normal to think about a design problem for days with no code written? [closed]

  - by Kim Jong Woo

  Sometimes I stare blankly into space or sketch ideas and write some pseudo codes on paper. Then I scratch it out and start again, then when I think I have the correct solution for the problem I begin writing the code. Is it normal to think for days without writing any code? Is this a sign that I am approaching the problem entirely wrong? It makes me nervous to not getting any tangible code written in my IDE.

• What are the most known arbitrary precision arithmetic implementation approaches?

  - by keykeeper

  I'm going to write a class library for .NET which provide an implementation of arbitrary precision arithmetic for integer, rational and maybe complex numbers. What best known approaches should I become familiar with? I tried to start with Knuth's TAOCP Vol.2 (Seminumerical Algorithms, Chapter 4 – Arithmetic) but it's too complicated. At least I couldn't get the ideas in a relatively short period of time.

• Enabling a multi display desktop completely broke Gnome Shell. Help?

  - by Chintan Parikh

  I've been trying to get my dual desktops working on Ubuntu for a while. I previously had them as one large desktop, but that was incredibly slow for some reason. I tried to switch them to multi display desktop on the AMD Catalyst Control Center. Here's what I get after restarting and logging in: http://i.imgur.com/SEjgU.png I'm running an AMD Quad Core A6, AMD Radeon 6540G2 GPU, 16GB Ram. Ubuntu 12.04 Any ideas?

• Rhythmbox is not launching

  - by Somogyi László

  I'm using Rhythmbox 2.99 in Ubuntu 13.10, and when I first launch the application it searches for music and works like a charm, but if I try to launch it later again nothing happens. When I run it in terminal I get this: $ rhythmbox (rhythmbox:8860): GLib-GObject-CRITICAL **: Custom constructor for class SoupServer returned NULL (which is invalid). Unable to remove object from construction_objects list, so memory was probably just leaked. Please use GInitable instead. Segmentation fault Any ideas how to make it work again?

• Incorrect Meta information in Google

  - by Ashfame

  Google shows up incorrect meta info (title & description) in search engine results for an add domain and the information is of the domain which is the primary domain of the hosting account. I mentioned this fact because add-on domains are in a sub-directory of the primary domain. Any ideas what could be the reason? Check this Google search which shows the information of http://katherinegaudette.com/

• How can I change the default screen resolution?

  - by TheWackerly

  Here's the scoop: I have a crappy VisionQuest TV that I am currently using as a monitor on my computer running XBMCbuntu. It defaults to 1280x768 which the TV will not display correctly. It appears to be the correct size, but the screen is panned WAY to the left. The TV works fine on 1024x768 with the screen sitting in the right spot. Problem is, I have to change the resolution to 1024x768 every time I boot up. Any ideas?

• Mapping local folder with an UbuntuOne folder

  - by Titus

  TrendMicro's Safesync has a nice feature, you can map your local folder to a folder in the cloud with a different name, e.g: PC1: C:\my_documents\pictures === office_pictures c:\my_documents\docs === office_docs PC2: C:\my_documents\pictures === private_pictures c:\my_documents\docs === private_docs Would this be possible with UbuntuOne? The reason is that I have multiple computers, and I don't want all my "my_documents" folders to sync across work and personal life... Thanks for a reply or ideas for workarounds! ;-) Titus

• finding houses within a radius

  - by paul smith

  During an interview I was asked given the following: A real estate application that lists all houses that are currently on the market (i.e., for sale) within a given distance (say for example the user wants to find all houses within 20 miles), how would you design your application (both data structure and alogirithm) to build this type of service? Any ideas? How would you implement it? I told him I didn't know becaue I've never done any geo-related stuff before.

• Google analytics and 301 redirects

  - by Ilian Iliev

  We have a multi language website and the first page redirects to specific language page using 301 redirect based on some logic. For exmaple: http://mysite.com/ redirects to http://mysite.com/en/ The problem is that these redirects destroy the primary request so we do not get correct results for traffic sources in GA. How do you handle this case? Is there something that we can do? Any ideas will be appreciated

• mod_rewrite capturing domain and tld

  - by sameold

  I'm using mod_write to rewrite this www.variabledomain.variableext to http://my.com/variabledomain.variableext Note that variabledomain and variableext are really variable, so I can't hardcode them. I'm not an expert at mod_rewrite, but I thought something like would work, but it isn't. Any ideas what I should be doing instead. RewriteRule ^(.*)\.(.*)\.(.*)$ http://my.com/$2\.$3 [R=301,L]

• 12.10: login screen never goes blank

  - by Marciano Siniscalchi

  I have installed the 12.10 beta (with all updates) on my iMac Early 2008. One annoying problem I'm having is that, when I log out of my account and go back to the login screen (lightdm, per default), the screen stays on: it never goes blank. This is not good for my display I guess! The screensaver (set to just a blank screen) works just fine when I'm logged in. The problem only appears at the login screen. Any ideas?

• Headphones don't work on an Acer Aspire 5920g

  - by Dave Chatelain

  All the problems I read about were all about the sound not working when they plugged the headphones in. I have the problem that my mic will work but the sound is still played on my built-in speakers. When I look at the sound settings, it doesn't give me any options for headphones. I run 12.04 and never had this problem in Windows. I run it on a Acer Aspire 5920g. Any tips or ideas will be very helpful.

• Sendmail on ubuntu 12.04 64 bit connection times out?

  Okay i get the following error message: to=<[email protected]>, ctladdr=<www-data@adam-linux> (33/33), delay=2+08:20:35, xdelay=00:00:00, mailer=esmtp, pri=25590437, relay=adamziolkowski.com., dsn=4.0.0, stat=Deferred: Connection timed out with adamziolkowski.com. I'm guessing to make sendmail work. I have to change the default outgoing port number to 465 because comcast blocks port 25. Any ideas? What could be causing this error?

• The partition table is corrupt

  - by Tim

  I have a corrupt the partition table on the laptop that is running Ubunutu 10.4. Before the partition table was corrupt I had the following partitions: 2 primary partitions: 1st - NTFS 2nd - Extended 4 logical partitons that are built within 2nd extended: 1st NTFS (68 Gib) 2nd Linux (19 Gib) 3rd Swap (1.4 Gib) 4th Linux (24 Gib) The physical order of these partitions was the following: ( 4th Linux ) - ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) The logical order of the partition was different: ( 1st NTFS ) - ( 2nd Linux ) - ( 3rd Swap ) ( 4th Linux ) NTFS partition was big and it resided between 2 Linux partitions, neither of these partitions had enough space to install Oracle 11g. Therefore, I decided to a) either move the NTFS partion to the left or b) remove it completely and extend partition where Linux resides. As I tool I have chosen GParted. But unfortunately it was not able to move the partition because he found that in NTFS partition there are some blocks that are referenced multiple times. Also it was not able to remove the partition neither, because in this case the partitions that follow it ( 2nd Linux ) - ( 3rd Swap ) have to be in his opinion also removed, because the organization of extended partition is a linked list. Since GParted was not able to do such thing I was trying to find another tool. I found diskdrake tool on PSLinuxOS distribution of linux. That tool silently deleted ( 1st NTFS ) partition and I thought that everything was fine. But diskdrake has damaged the partition in a way that I am not able either to boot from the hard disk nor to see the partitions with GParted and even with diskdrake itself! Fortunately I have a live CD of Ubuntu 8.10 and I am able to boot and see hard disk. I have 2 ideas how I can solve the problem: 1) Manually change disk partitions and point them to the correct partitions. 2) Create partition table with GParted that as much as possible is the same with the previous one I find the 2nd approach less time consuming but some data will be lost because of it is not possible to place borders of the partitions exactly how it was before. And moreover I am not sure if such approach would work, for example, if the OS is able to locate files after repartitioning. I feel like that it will but not 100% sure. Are there some ideas how the problem may be solved?

• How can I make a webmail URL available from any hosted domain?

  - by James

  I run Roundcube webmail on my VPS. At the moment, it is only accessible from one virtual server hosted on the server, unless a separate Roundcube installation is created for other virtual servers. I would like to be able to make webmail available from any domain/ virtual server that I host, just by adding /webmail to the end. I'm sure Apache must allow me to do this - only problem is, I don't know how! Any ideas?

• How to configure an Ubuntu 12.04 virtual server and VMWare ESXi5 the way VMWare would be able to shut it down properly?

  - by Ivan

  I run an Ubuntu 12.04 server as a virtual machine on a VMWare ESXi 5 server. I've configured VMWare to shut the quest machines down the sane way (with an ACPI (if I understand it righ) shutdown signal so that guest OSes would do it). And this works with other VMs (running Windows 7 Professional and openSuSE) but doesn't work with the Ubuntu server - VMWare still offers just to power them off when I ask it to stop the guest. Any ideas how to fix this?

• How to dynamically generate PDF documents

  - by Thomas

  I want to build a web application for generating stylish PDF documents. The layout should be based on a design templates and the data should come dynamically from the database. Ideally I want to design the template in a "publishing like" tool with placeholders and replace these placeholders by the web application with the data from the database. Think of something like an invoice generator, where a customer could choose from different invoice templates and the invoice data itself coming from the DB. Thanks for your ideas!

• A way to store potentially infinite 2D map data?

  - by Blam

  I have a 2D platformer that currently can handle chunks with 100 by 100 tiles, with the chunk coordinates are stored as longs, so this is the only limit of maps (maxlong*maxlong). All entity positions etc etc are chunk relevant and so there is no limit there. The problem I'm having is how to store and access these chunks without having thousands of files. Any ideas for a preferably quick & low HD cost archive format that doesn't need to open everything at once?
