• Best practices for versioning project after dependency upgrade

  - by shabunc

  Say, my project have dependency N with version 1.0.0. Then something have changed, and I should depend on newer version - let it be 1.0.1. OK, I'm incrementing dependency version, nothing else changes in my code. It looks like I should increment my own projects' version, but how exactly I should increment? Should I increment only third number (so-called revision), or best practices here are more complicated. For example, may be, if we are changing projects' dependency minor value, we should do the same thing in the project itself?

• How can i add more wallpapers in 11.10?

  - by bjnobrega

  How do I increase the amount of wallpapers that appear on the menu for customizing the desktop with my backgrounds in 11.10? I added more images to the respective folder in /usr/share/background as root, but the list does not remain persistent. The images in 11:10 changes alone. So I want to add funds to enhance the environment. When I copy the images to the folder /usr/share/backgrounds the list is updated and increased. But only for the first time. Thereafter, the system ignores the other images, and the list of funds has become original as first. Any help?

• Google Webmaster Tools Index dropped to Zero [closed]

  - by Brian Anderson

  Earlier this year I rebuilt my website using ZenCart. Immediately I saw a drop in index status from 59 to 0. I then signed up for Google Webmaster Tools and noticed the Index status took a dramatic drop and has never recovered. I have worked to add content and I know I am not done, but have not seen any recovery of this index since. What confuses me is when I look at the sitemap status under Optimization it shows me there are 1239 submitted and 1127 pages indexed. Most of my pages have fallen off page one for relevant search terms and some are as far back as page 7 or 8 where they used to be on the first page. I have made some changes in the past week to robots.txt and sitemap.xml, but have not seen any improvements. Can anyone tell me what might be going on here? My website is andersonpens.net. Thanks! Brian

• 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?

• broadcom 43225 wireless on acer laptop is disabled

  - by Robbie

  I have a acer aspire 5820T with a broadcom 43225 wireless card. I previously used ubuntu 10.10 and the wireless worked straight away, but when I updated to 11.04 the wireless stopped working. I have managed to get the wireless hardware to switch on for a couple of seconds before turning off (When you turn the wireless on using the manual switch the wireless light stays on for a couple of seconds and in the drop down connections menu the information under wireless networks changes from 'device not ready' to 'Disconnected' but shows no wireless networks despite there being one). So far I have tried installing an additional driver, and also disabling the additional driver and installing b43-fwcutter and firmware b43 installer. There may have been other things that I've found in searches that i've tried but unfortunately I can't remember them. Any help would be appreciated.

• How to change icons of specific file types on Ubuntu 11.10?

  - by Curious Apprentice

  I want to change file icons of some specific file types like- .html, .css etc. I have tried using "File Type Editor (assogiate)" which is not working. I have also tried using "Gnome Tweak Tool" using icon themes. But that also does not worked properly (Though I can change folder icons , dash menu icons but not file icons). Please suggest me a way so that I can change file icons properly. I have read some of the articles saying about some mime type changes. I could not get proper guide from any of those articles. If there is such a way then please write in detail. Many Many Thanks in Advance :)

• Debugging-Setting Consoles in Games

  - by ShrimpCrackers

  Right now I have the graphical and input portions of a console for my game (command parsing hasn't been implemented yet). I was wondering how you would go about making changes to properties in game objects. For example, if I typed in the console: skeletonMonster maxHP 20 That would change all of the existing in-game skeletons' max hit points to 20. After you parse this information what are some ways to change the value? How can I change the variable(s) without violating information hiding? I'd like to implement this so I don't have to change variables in the code and recompile every time while playtesting.

• Fast Track Data Warehouse 3.0 Reference Guide

  - by jchang

  Microsoft just release Fast Track Data Warehouse 3.0 Reference Guide version. The new changes are increased memory recommendation and the disks per RAID group change from 2-disk RAID 1 to 4-Disk RAID 10. Memory The earlier FTDW reference architecture cited 4GB memory per core. There was no rational behind this, but it was felt some rule was better than no rule. The new FTDW RG correctly cites the rational that more memory helps keep hash join intermediate results and sort operations in memory. 4-Disk...(read more)

• When dealing with a static game board, what are some methods to make it more interesting?

  - by Ólafur Waage

  Let's say you have a game board that you look at. It does not move but there is some action going on. For example Chess, Checkers, Solitaire. The game I'm working on is not one of this but it's a good reference. What are some methods you can apply to the game or the design that increases the appeal of the user to the game. Of course you can make it prettier but what are some other methods you can use? For example: Visual cues, game design changes, user interface arrangement, etc.

• Have you worked with a well designed application?

  - by Vilx-

  Inspired by this question, I started wondering - is there or has there ever been such a thing as a "well designed application"? One where the architecture would be perfect and no refactoring would ever be needed; code would be easy to read and understand even for someone new to the project; changes could be done with a 100% certainty that they won't break anything; etc? I must admit that whatever codebases I've worked with, they've all been more or less a mess. Even code that I start myself only stays organized at the start, and then slowly deteriorates as the time passes. I'm even starting to accept this as part of life and can't figure out whether I should be worried about that or not. So... is there such a thing as a "well designed application"? Or is all our code so shitty that there isn't even a point in trying to make it better, because it will never be good anyway?

• Useful git commit messages for merged branches

  - by eykanal

  As a follow-up to this question: If I'm working on a team by myself, I can maintain useful commit messages when merging branches by squashing all the commits to a single diff and then merging that diff. That way I can easily see what changes were introduced in the branch, and I have a single summary describing the feature/change/whatever that was accomplished in that branch when browsing the master branch. My question now is, how can I accomplish this when working with a team? In that situation, the branches will be pushed to a remote repository, meaning that I can't squash all the commits in the branch down to a single commit. If the branch is public, can I still have a single useful merge commit in the master branch? (By "useful" I mean that the commit in the master line tells me (1) a useful summary of what was done in the branch and (2) diffs of the same.)

• Is it possible for a good programmer to have never used version control?

  - by lortabac

  I am looking for an expert programmer to help solve a difficult situation. The interviews so far have been surprisingly disappointing. The best candidate so far is a very experienced programmer who has never used version control software. The problem in itself might not be too serious because it is something which can be learned in a short time. But there is a deeper aspect, which worries me: How is it possible to actively develop software for 10-15 years without ever needing version control? Is the fact itself of not looking for a solution to the problem of tracking changes a sign of a wrong attitude to programming?

• Good resources for learning about graphics hardware

  - by Ken

  I'm looking for some good learning resources for graphics hardware (and associated low level software). Basically I want to learn more about what goes on underneath the opengl/direcx API layers in terms of how things are implemented. I familiar with what happens in principle during the various stages of the rendering pipeline (viewing, projection, clipping, rasterization etc). My goal is to be able to make better and more informed decisions about tradeoffs and potential optimisations when graphics/shader programming with respect to the following kinds of issues; batching view culling occlusions draw order avoiding state changes triangles vs pointsprites texture sampling etc Basically whatever the graphics programmer needs to know about modern graphics hardware in order to become more effective. I'm not really looking for specific optimisation techniques, rather I need more general knowledge so that I will naturally write more efficient code.

• ASP.NET MVC Portable Areas - Can they communicate and be used as a plugin-like architecture?

  - by Beton

  I'll get straight to the point: I was wondering if there is a common pattern to use portable areas as a components of a plugin-like architecture. Example: We've got 3 plugins (portable areas) packaged and distributed via NuGet feed. Each of them is following the standard MVC structure (has it own Models, Views and Controllers). Lets say login form, header and footer. What I was wondering if there is a way to make them communicate. For example: when user logs on, login plugin executes it own logic, logs the user and then it updates the state of the header plugin with changes it state accordingly. Thanks in advance.

• What is supposed to happen when you install Gmail webapp?

  - by ubuntico

  I have installed Gmail (and other Google as well) webapps into Ubuntu 14.04 64-bit. After that I rebooted the system hoping that webapps will integrate into the system. But after logging back to the system, I see no changes. If I click on email envelope (top bar), I don't see my inbox. Also if I try to search email in Dash via gmail keyword, nothing happens as well. Am I using this wrongly or webapps don't work? What was supposed to happen when I install webapps? Note: I did start the Gmail app from Dash and logged in

• Problems with NAT Adapater since upgrade to Ubuntu 12.10

  - by jjesse

  I was running Ubuntu 12.04 w/ VirtualBox installed. I was using the NAT interface to connect to everything. Basically running VBOX for testing some things and a Windows VM for Netflix.. Was back to working in my VMs today and noticed that I was unable to connect to the internet. In the VM settings I'm using the NAT adapter, however I noticed there is no NAT adapter in the Network Settings under Preferences in VBOX. Not quite sure what happened but wonder what is going on? I noticed there are some posts about changes DNSMASQ and configuring a bridge mode, but this worked out of the box under 12.04 and since the upgrade this no longers work. Need some help please

• How can I make sure my website will be available during a presentation?

  - by johnny_s

  I have an online presentation to do next week and I have it all ready to go. The website is HTML and CSS only (no DB), and currently resides on my shared hosting account. Now, although my shared hosting is (relatively) reliable, I have noticed that recently they have been making some changes and my website has been unavailable at times. I don't want this to happen to me on the morning of my presentation, so I am asking what is the best way to prepare for such a thing? My domain is www.presentation.mydomain.com and I would like to keep this if possible (even if issues arise). I have been thinking of a few alternatives: Host my site on two different domains or servers (but what about the domain name?) Have a portable XAMPP version on a USB stick (again, domain name?) Possible failover site/location Update: The presentation will be carried out on their laptop, not mine. So I am unable to install any software.

• How to edit files in a terminal with vim?

  - by andrew.46

  It is not always possible to edit and create files in a terminal and I would like to get the answers to the basics of manipulating files in a terminal using vim under Ubuntu Linux. Specific questions I have are: How can I open text files for editing? How can I save the file? How can I save the file with a different name? How can I leave the file without saving the changes? What settings are best in my configuration file and where is this file? How do I set the colors for vim? How do I show line numbers in vim and can this be toggled? A lot of questions here but I believe these questions and their answers should cover basic vim usage...

• How to organize my site's file system properly?

  - by Wolfpack'08

  Doing some reading on Stack Overflow, I've found a lot of information suggesting that proper organization of a file system is crucial to a well-written web app. One of the key pieces of evidence is high-frequency references to "separation of concerns" in questions related to keeping programs organized. Now, I've found some information on organizing file systems (Filesystem Hierarchy Standard) from 2004. It raises only two concerns: first, the standard's a bit dated, so I believe it may be possible to do better given the changes in technology over the past 8 years; second, and most important, my application is very small compared to an entire Linux distro. I think that the file system should be organized very differently because of that. Here's what I'm looking at, currently: /scripts, /databases, /www -> /dev, /production -> login, router, admin pages, /sites -> content types, static pages /modules, /includes, /css, /media -> /module-specific-media

• aticonfig detects all graphics cards, but amdcccle shows the cards as disabled

  - by DevZer0

  I been having the strangest problem since few days ago. I have 3 ATI graphics cards and the aticonfig --list-adapter shows the following output * 0. 01:00.0 AMD Radeon HD 7900 Series 1. 02:00.0 AMD Radeon HD 7900 Series 2. 05:00.0 AMD Radeon HD 7900 Series when i do aticonfig --adapter=all --initial -f it generates the correct X config also. but after rebooting the output only show on primary monitor and when i look in amdcccle it shows the other 2 adapters as disabled. I tried with monitors attached and dummy plugs both but the situation doesn't change. Any idea whats causing this? also right clicking and making the adapter enabled in amdcccle and saving changes causes the X config to only have the adapter section and no screen section. after reboot the situation stays the same.

• Public versus private inheritance when some of the parent's methods need to be exposed?

  - by Vorac

  Public inheritance means that all fields from the base class retain their declared visibility, while private means that they are forced to 'private' within the derived class's scope. What should be done if some of the parent's members (say, methods) need to be publicly exposed? I can think of two solution. Public inheritance somewhat breaks encapsulation. Furthermore, when you need to find out where is the method foo() defined, one needs to look at a chain of base classes. Private inheritance solves these problems, but introduces burden to write wrappers (more text). Which might be a good thing in the line of verbosity, but makes changes of interfaces incredibly cumbersome. What considerations am I missing? What constraints on the type of project are important? How to choose between the two (I am not even mentioning 'protected')? Note that I am targeting non-virtual methods. There isn't such a discussion for virtual methods (or is there).

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.
