• Nautilus is extremely slow

  - by Maxim

  I am on Ubuntu 11.04. And Nautilus is very slow. It opens directories for 3-5 seconds even if a directory contains just a few small files. Even selecting of a file or directory with narrow keys is extremely slow and it rises my CPU usage up to 100%. It makes it almost unusable. But I noticed that if I start my nautilus as superuser: $ gksu nautilus then it works just fine. It is fast and responsive. So what can I do to fix this? Any help is really appreciated.

• Good interview programming projects

  - by bigtang

  I'm looking for some small programming projects that I can give potential employees to gauge their programming abilities. These will be programmers straight out of college. I'm looking for projects that would take someone a couple of hours and they would email back their answers post-interview. One example would be to take this paragraph of text and return a list of alphabetized unique words. After each word tell me how many times the word appeared and in what sentance(s) the word appreared in. Anyone have any good suggestions?

• How do I install a driver for a Kodak esp 3250 printer?

  - by user108608

  First my system: pentium 4 -don't remember the speed-, 1g ram, dual boot to separate physical drives, Fdos and Lubuntu 12.1 second my lan: I have four computers operating for the same printer. Intel quad core i5, 4g ram, running Windoze 7 64 bit, printer connected and shared from here. Kodak ESP 3250 Gateway 17" laptop running Windoze 7 32bit Asus tablet (small laptop) running Lumbutu 12.1 My dual boot system running Fdos and Lubuntu 12.1 The problem: I downloaded c2esp_25c-1_i386.deb, tried to install it using DEBI Package Installer, it loads the files, looks for cups driver and ends with an error: "Dependancy is not satisfiable: libcupsdriver1 (=1.4.0)" What do I do now? Is there some place that I can get the correct cups driver? further information: The Asus tablet was running Ubuntu 12.1 (very slowly and with a few crashes) and could print from the lan printer with no problems. Is there something in Ubuntu that can be loaded into Lubuntu?

• seo value of duplicating content externally

  - by Don

  I run a website that includes a blog which was hand-coded by myself and is hosted on the same domain. My partner in this endeavour thinks it would be a good idea to open up a blogger/wordpress blog and duplicate the on-site blog on this off-site blog. AFAIK the main reason for doing this is the SEO benefits of the inbound links that this off-site blog will create. I think this is a bad idea, because: Effectively what we're doing is creating a (very small scale) link farm We're more likely to be punished than rewarded (in SEO terms) for duplicating our content across domains This introduces a problem of synchronising our content across domains. For example, if a blog post is edited on the on-site blog, then ideally the off-site blog should be similarly updated. I know very little about SEO, so would be interested to hear what more informed readers have to say.

• Duplicate pages indexed in Google

  - by Mert

  I did a small coding mistake and Google indexed my site incorrectly. This is the correct form: https://www.foo.com/urunler/171/TENGA-CUP-DOUBLE-HOLE But Google indexed my site like this: https://www.foo.com/urunler/171/cart.aspx First I fixed the problem and made a site map with only the correct link in it. Now I checked webmaster tools and I see this: Total indexed 513 Not selected 544 Blocked by robots 0 So I think this can be caused by double indexes, and it looks like the pages not selected makes the correct pages not indexed. I want to know how to fix the "https://www.foo.com/urunler/171/cart.aspx" links. Should I fix in code or should I connect to Google to re-index my site? If I should redirect wrong/duplicate links to correct ones, how should that be done?

• Ready to Open source the software, but want to make some money out of it.

  - by byteofprash

  I'm an UG Student and an Entrepreneur. I have started a small company with which I'm trying to provide solutions, to various companies in my city, through my software. I put in 30-40 hours of coding and development. I've been a huge fan of Open Source projects and I've also built by software on python. But now when it comes to selling my software to my customers, I expect money. (Am I being a Hypocrite?) Is there any OSS license under which I can make money and also make my source open? Please suggest. Or any other way to make money with my softwares? (I guess I deserve some credit. If not the code, atleast the ideas? :D )

• How can I handle this string concatenation in C in a reusable way

  - by hyphen this

  I've been writing a small C application that operates on files, and I've found that I have been copy+pasting this code around my functions: char fullpath[PATH_MAX]; fullpath[0] = '\0'; strcat(fullpath, BASE_PATH); strcat(fullpath, subdir); strcat(fullpath, "/"); strcat(fullpath, filename); // do something with fullpath... Is there a better way? The first thought that comes to mind is to create a macro but I'm sure this is a common problem in C, and I'm wondering how others have solve it.

• Feedback/bug tracking system for an alpha/beta phase website? [on hold]

  - by randomguy

  I'm developing a website and it's closing onto a private alpha/beta phase. It will be exposed to a small selected group of individuals who will provide a fair amount of feedback. What options do I have for this feedback system? I would certainly like to make it collaborative (excluding email). I could mock up a really simple message board, but would rather use my time elsewhere. The feedback will mainly consist of feature suggestions and bug reports. Edit: Actually, would prefer if it's a free hosted service.

• What made you contribute to that open source project? [closed]

  - by Ermin

  I'm interested in real experience and personal answers not just those standard worn out "benefits of contributing to open source" that we all memorized by heart by now. I've met many people who contribute to open source project and almost never did this topic come up: why did they contribute to this open source project. So, if you've contributed to an open source project before in any way, can you please pause for a second and try to remember what really made you decide to contribute to that particular project. Was it a random decision, was it because you were bored, was it because the company you worked for was already using it and you contributed as part of your job, was it because the project was too big you wanted to get contracts, or the project was too small you wanted to build it, or because your prof or co-worker asked you to help with his open source project, or..... To substantiate your reasons, please mention the project name and rate your involvement (heavy, occasional, light, once).

• Why can't I view a specific websites?

  - by user79263

  I am a netwrok administrator at a small company (22 PC) and i have a problem, and i don't know which could be the cause. I can't access a specific website from the LAN. I have a server which has 2 NICs(one to ISP and one to LAN). I have installed on the server (Bind DNS server and DHCP server) Debian 6 Server. I want to mention that "nslookup mcel.co.mz", and "dig my_site" is not working perfectly, I can't access the site from inside the LAN. I can't send emails to person that are located in that domain. When I dig mcel.co.mz @8.8.8.8 the domain is resolved. Why can't I view a specific websites? www.mcel.co.mz Why can't send email to person that are on some domains? @mcel.co.mz I don't have any rule configured in Debian Server which wouldn't let me acces the site. I am the only one responsable with the IT department. Lowly,

• If a company is using ubuntu on its servers/dektops, does it have to pay?

  - by rsjethani

  a friend of my friend has started a small firm and given me the responsibility to erect all the IT infrastructure required? I'm basically a windows guy that too on the developer side. But recently I fell in love with Linux n dared to dream about becoming a Linux admin and play with Linux, virtualization, cloud etc. So, first I'll be running a pilot project of creating mail/ftp/web servers required on a Linux based server. And Ubuntu is the ideal choice for a Linux beginner right? my question is simple: if a commercial organization is using Ubuntu for it's day to day desktop and server(mail,ftp etc) uses but has technicians which can provide support internally then do the organization needs to pay for Ubuntu? If yes then could you please suggest a Debian based distro on the lines of CentOS. Also can I use the Ubuntu 12.04 LTS 64 bit desktop version instead of the no gui server version for the server machine(gui can be helpful for a windows guy like me) thanks.

• What are some advantages / disadvantages to working on a remote development machine?

  - by robertpateii

  At home I have a fast rig with my dev environment running in virtual box. that works great, but at work I have a so-so laptop that can barely push visual studio express, outlook, and a dozen chrome windows at the same time. So I can either ask for a dedicated desktop to do development on, or I can ask for a slice on an existing server from IT and remote into it. Setup-wise, the remote option is faster and cheaper. But I don't know its affect on production in the long term. I've done small amounts of work through a remote connection, but never extended development. Do you have experience with this? What are some of the ads/disads to it? Did it make you less productive?

• Free serif font with clearly distinguishable 0 (zero) character

  - by l0b0

  I'm using gLabels to create some small pieces of paper to give away to people - Just two lines of about 15-20 characters each. One of the important parts of the design is that there are no "o" ("oh") characters, but there are "0" ("zero") characters in an all-lowercase URL. Therefore I need a non-monospaced (and very legible in print) font where "0" cannot be confused with "o" even without reference. The closest thing I've found so far is Andale Mono and Inconsolata , but they are both monospace, and as such not very easy to read in print. Alternatively, to find a font myself, is there some way to preview all fonts in the Ubuntu repositories without installing them?

• How to syncronize two animations without delays

  - by GeKi

  I have one character idle animation running inside a game in a loop, over and over again. A a certain time I trigger another animation to be played, for the same character. The second animation won't play immediately, as will be a discontinuity in my character animation. First I wait for the idle animation to finish and then I play my second animation. Now I have a smooth, continuous animation, BUT I have introduced a delay between my action and character animation. If I play the second animation right away as it is triggered, the character animation won't be continuous and smooth. I was thinking on breaking the idle animation in small pieces and also to have the same number of second action animations to match the last frame of the idle pieces. This won't solve the delay completely, only will minimize it a bit. So it's a magic formula of how can I get rid of this delay? Thanks.

• Syncing properties across a game server

  - by Vaughan Hilts

  I'm beginning to implement a simple scripting system into my networked server, and I've hit a snag. Before, I've been wrapping my calls into functions on objects that manipulate objects, but lately I've been finding this to be a pain for simple things. For example, if I set 'player.HP = 1'.. this works server-side. But the player side never sees this change unless I explicitly send a packet to inform the client. For many things like map swapping that require more complicated changes, like change X, Y, Map and do this.. I have a function. That's fine. But what about these small properties I want to sync?

• How can I increase the text size in empathy chat windows?

  - by skyblue

  The text that appears in empathy chat windows is quite small, even though I have set the font DPI to a large value in Preferences Appearance. There does not appear to be any option to make this larger so that I can read what other people are sending me easily. I've been using pidgin in the meantime because it is a little better in this respect. I would be grateful for any tips on how to increase the text size in empathy chat windows, even if this involves clever .gtkrc-2.0 hacks. Thanks!

• Distorted graphics, problems with starting up

  - by GreenEggsAndHam64

  Using the newest version of Ubuntu, freshly installed. NVIDIA GeForce GTX 560 Ti. It's mostly the font that doesn't render well, I think. Small logos do it too, sometimes. Screenshot to clarify (see bookmarks, search bar, etc.). EDIT: Another screenshot. And, sometimes when I start up, I get only a black screen saying [OK]. I can move my mouse around, but nothing helps, except for restarting. Also, my desktop picture doesn't stay the same. Every time I start up Ubuntu it goes back to the standard purple background. They're not very serious problems, but it's all a little annoying. Thanks in advance for your help.

Is there any way to render/create the change log at the build time (maven). How do i manage the change log for all version or Patch updates during build time? (Automatically)

• Writing scripts for Visual Studio project

  - by oillio

  What is the best way to write and run small scripts and tasks that are specific to a particular .Net project? Such things as configuring a database or confirming proper connections to servers. In Ruby, I would build rake tasks for this sort of thing. I am currently using unit tests for these tasks as they are easy to run within VS and they have access to all the necessary libraries and project code. However, this is not really their intended purpose and, with the dropping of Test Lists in VS 2012, it does not work nearly as well as it used to. Is there a better solution than writing a console project to handle these little code snippets I need to run periodically?

• Architecting persistence (and other internal systems). Interfaces, composition, pure inheritance or centralization?

  - by Vandell

  Suppose that you need to implement persistence, I think that you're generally limited to four options (correct me if I'm wrong, please) Each persistant class: Should implement an interface (IPersistent) Contains a 'persist-me' object that is a specialized object (or class) that's made only to be used the class that contains it. Inherit from Persistent (a base class) Or you can create a gigantic class (or package) called Database and make your persistence logic there. What are the advantages and problems that can come from each of one? In a small (5kloc) and algorithmically (or organisationally) simple app what is probably the best option?

  I'm currently maintain a large project with more than 100000 LOC. The code use the MFC as its framework, in genral, it only has interface part which heavily use the mfc api and a business logic part which full of bad code, confusing logic. The company has some small features delivered to the customer each year(most features are adding code to exisiting project, finding some reference of some api or variable and it' s no different with fixing 3-4 bugs ), most of the tasks are to resove issue and optimize performance . Like other company with maintaining position, it value people who knows much logic about its product. There are people who can quickly finish the job on such project, is it worth to train myself like such a programmer? Is there benifits to work on such project for a long time?
