• Any pre-rolled System.IO abstraction libraries out there for Unit Testing?

  - by Binary Worrier

  To test methods that use the file system we need to basically put System.IO behind a set of interfaces that we can then mock, I do this with a DiskIO class and interface. As my DiskIO code gets larger (and the grumblings from the we're unconvinced about this TDD thing crowd here in work get louder), I went looking for a comprehensive open source library that already does this and found . . . nothing. I may be looking in the wrong place or have approached this problem in completely the wrong way. I can't be the only idiot in this position, do these libraries exist, if so where are they? Any you've used and would recommend? Thanks P.S. I'm happy with my current approach i.e. starting with what we need, and adding only when the need arises. Unfortunately the we're unconvinced about this TDD thing crowd remain unconvinced, and think that I can't be right.

• UI font has rendering glitches in GNOME Shell

  - by user353889

  I don't really know how to describe this problem in English. A picture can say more words - look at the tabs at the top of the linked image. The current font settings are shown as well. I don't know what basic info I should provide so if something missing, please tell me. Ubuntu 12.04 GNOME Shell 3.4.1 I know, a reboot can make everything normal but I'm looking for a more permanent solution that can fix this problem (or bug). Update Thanks for Fitoschido, I finally know what keyword I could use for googling. I think it's a bug of gnome shell. https://bugs.archlinux.org/task/34847

• Mouse and keyboard focus problem

  - by heffaklump

  I have two Chrome windows side by side. I click a link in window#1, ok. Now I want to switch to window#2 and click anywhere in the window. Noting happens. Sometimes the cursor switch to make-bigger-window style. If I click in the top part of current window. And then in the top part of next window I can switch focus so the other window works. Another problem is that the keyboard focus can get stuck in one window. I can click on things in one window but when using the keyboard it will change the first window. Only by closing the window that has the focus, it will release keyboard. What is this madness? Another problem not related is that sometimes I get logged out. Just like that.

• Ubuntu user expectations from 12.04 and future releases

  - by Rick Green - Turbo

  How much further ahead is 12.10 vs 12.04 in respect to kernel updates and applications? Example: Gimp's newest release is 2.8 which runs equally as well in both 12.04 and 12.10 and probably will in 13.04. What restricts 12.04 from having "the same" look, feel, applications and kernel as 12.10 or the upcoming 13.04? I know that it's more than a name change.....it's whats under the hood that counts. Incrementally upgrading, I feel is safer than radical changes from release to release. Trying to keep a stable desktop and current user experience, how far can I take updating applications before I absolutely have to make a distro upgrade from 12.04LTS

• Move site to new domain divided by language across subdomains

  - by mark

  I managed to find a nice domain for a fairly fledgling site of mine that actually hasn't been parked by scumbag squatters. Given the upcoming move I'm thinking I'd take the opportunity to split the content across subdomains according to language, much like wikipedia for example: current: www.old-domain.com/en/subject # English www.old-domain.com/subjecto # Spanish (default so not locale in url) proposed en.new-domain.com/subject es.new-domain.com/subjecto The advantage of doing this is a fairly competitive keyword such that I may wish to put a copy of my application on a Spanish slice in order to gain a few serp's. Also pure vanity. Google's webmaster tools allows me to move to the new domain and I can add the root domain and the subdomains but forward to only one. I'll 301 from the old domain appropriately but is there anything I should know about webmaster tools in this respect where effectively I'm moving to two addresses? (Feel free to dissuade me from doing this if it's a bad idea in comments.) I've now asked this same question on google's forums.

• Extracting, Transforming, and Loading (ETL) Process

  The process of Extracting, Transforming, and Loading data in to a data warehouse is called Extract Transform Load (ETL) process.  This process can be used to obtain, analyze, and clean data from various data sources so that it can be stored in a uniform manner within a data warehouse. This data can then be used by various business intelligence processes to provide an organization with more of an in depth analysis of the current state of the company and where it is heading. A standard ETL process that might be used by a health care system may include importing all of their patients names, diagnoses and prescriptions in to a unified data warehouse so that trends can be spotted in regards to outbreaks like the flu and also predict potential illness that a patient might be affected by based on other patients with similar symptoms.

• W520 External monitor setup with Ubuntu 12.10

  - by user108372

  I just installed a fresh Ubuntu 12.10 64-Bit Desktop on my Lenovo W520. It looks like there are a lot of challenges around making it work with out of the box Nouveau drivers or propriety Nvidia drivers or Intel GPU. I looked at couple of notes on how to make it work with Bumblebee with Optimus Nvidia. None of them seems to work for 12.10. Anybody has a solid answer on this? It seems like a lot of people are suffering from this. Here is my xrandr output. Let me know if you need any additional information. Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 1920x1080 60.0*+ 59.9 50.0 1680x1050 60.0 59.9 1600x1024 60.2 1400x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Thanks, Sef

• What effect does using itemprop="significantLinks" on anchors have for SEO and what is the ideal use?

  - by hdavis84

  I'm practicing application of microdata via http://schema.org. Anyone who's browsed the documentation there knows that there's a lot of need for improvement for more clear understandings on use for each property. My question on this post is more about the "significantLinks" property and how it effects SEO for on page, in content anchored text. Does anyone have any more information regarding whether its good to use for link optimization? I understand what schema.org means that it's to be used on "non-navigational links" and those links should be relevant to the current page's meaning. But will using this property hurt SEO or make SEO better for each page?

• How do I stop banshee remembering what's been played?

  - by dunderhead

  How can I prevent Banshee from remembering what files I have played? I really hate the way it keeps surprising me by automatically playing, after the current track, the previous file it had played. I really HATE that. I was just listening to a beautiful piece of music and in a nice mood when Banshee, without asking me, immediately afterwards, started playing a really annoying answerphone message from earlier. My solution so far is to manually delete all files in the playlist, but obviously that's not a long term solution. I cannot find an option anywhere that says "Do not remember my history" (Did I mention I hate the way Banshee plays my files without asking me?)

• What is the best stucture of SEO friendly URL?

  - by Aajahid

  I'm working for a website to convert the website URL to an SEO friendly URL. I plan to use this: mysite.com/category-name/pageid-123-page-name I looked at some similarly categorized, highly ranked websites. They have the same structure, except for one thing. In one case, the URL format was thissite.com/category-name/pageid-123-page-name.html Another was thatsite.com/category-name/pageid-123-page-name.php Now I know the text in URLs help with SEO. Is it more helpful to have a file extension? If yes, which one is better? Or if my current plan is okay, will it be better with a / at the end?

• As a programmer, are you required to do timesheets?

  - by vcsjones

  Timesheets are something that I've never been fond of, but non-the-less something that is a requirement within my company. They don't bother me so much, but they seem to really grind some other people's gears. I suppose I have a few questions, and feedback would be great. Are you required to do timesheets, assuming you aren't a contractor? (That is understandable to me). What is the granularity of timesheets that you would be comfortable with or that you use? (ex: all entries must be under two hours). Would timesheets ever factor into your reasons for not accepting a job or leaving a current one? How has management within your organization justified timesheets if you aren't billing to a client?

• Joining and compressing all javascript files together - good idea?

  - by Tomáš Zato

  Curently, I avoid loading any unnecesary scripts on individual pages of my site. I have a class that remembers all javascript files that were requested during PHP processing and adds them to HTML. I was just thinking that I could merge the current set of files, save the result in special directory and let the browser download just one, big file. Since the number of possible combinations is not very high, I would end up with about 10 combined files for different pages. I've never seen that on any site. What are the reasons not to do it? I need very fast page load.

• Does an inventory limit in an MMORPG make sense?

  - by Philipp

  I am currently developing a simple 2d MMORPG. My current focus is the inventory system. I am currently wondering if I should implement a limit on what a player character can carry. Either in form of a maximum weight, a limited number of inventory slots, or a combination of both. Almost every MMORPG I ever played limits inventory space. But plausibility aside, is this really necessary from a gameplay point of view? Maybe it would in fact improve the game experience when I just let the players carry as much stuff as they want. tl;dr: What is the game development rationale behind limiting carrying capacity of player characters?

• How to push through a domain transfer in spite of the 60 day rule

  - by corsiKa

  I recently purchased a domain through a registrar which I won't name here. Within the first five minutes of logging in, I found a severe vulnerability that allows me access to all registration details of all users. Simply put, I do not trust this registrar with any kind of business. But I'm unable to transfer the domain because, for some reason, it has to exist in its current state for 60 days. We're planning to launch the site this weekend - we can't wait 60 days. But I can not trust this registrar: if I found such a severe vulnerability in the first few minutes, how many more similar un-trustables will I find in those 60 days? Is there a higher authority to whom I can submit a case to get my domain transferred to a different registrar?

• Advice on approaching a significant rearrangement/refactoring?

  - by Prog

  I'm working on an application (hobby project, solo programmer, small-medium size), and I have recently redesigned a significant part of it. The program already works in it's current state, but I decided to reimplement things to improve the OO design. I'm about to implement this new design by refactoring a big part of the application. Thing is I'm not sure where to start. Obviously, by the nature of a rearrangement, the moment you change one part of the program several other parts (at least temporarily) break. So it's a little 'scary' to rearrange something in a piece of software that already works. I'm asking for advice or some general guidelines: how should I approach a significant refactoring? When you approach rearranging large parts of your application, where do you start? Note that I'm interested only in re-arranging the high-level structure of the app. I have no intention of rewriting local algorithms.

• Saving more corsor positions (with tput?) in bash terminal

  - by AndreasT

  I know that tput sc saves the current cursor position and tput rc restores it exactly where tput sc was called. The problem is that every time tput sc is called, it overwrites the previous saved position. Is there a way to save more positions, e.g. tput sc pos1 and tput sc pos2 which can be restored with, say, tput rc pos1 and tput rc pos2 respectively? (The solution need not make use of tput, I mentioned it because it's the only command I know that handles cursor position) If not, is there a way to at least save the cursor position locally in a function, so that if a function uses tput sc and then calls another function that runs again tput sc, then each function restores its own saved cursor position when invoking tput rc? Thanks in advance.

• Can I use my VirtualBox 3.* VMs with VirtualBox 4.0? If so, how come the repository doesn't have it?

  - by ximbim

  I had the following repository for virtualbox in my /etc/apt/sources.list: deb ttp://download.virtualbox.org/virtualbox/debian maverick non-free Then I found out there was a new version when I opened it today (the program prompted me with a window to manually download it from Oracle's site). Then I tried sudo apt-get update && sudo apt-get upgrade and got nothing. Here you have a way to add virtualbox-4.0 to your apt-get, but the problem is that it isn't updating, meaning I would have the two installed. I'm also worried if I'll have to do something like that each time it updates since that would defeat the point of apt-get. I've been using virtualbox with the apt-get update for more than a year now and this is the first time it has happened, so I was wondering if there would be a way to just update my current installation.

• Problems with Ranking when Using Sourcing Rules And ASLs From Blanket Agreements?

  - by LisaO

  Are you using Sourcing Rules and Approved Supplier List with Blanket Purchase Agreements (BPA) and it seems like Ranking is not working correctly? For example:  The Sourcing Rule being used, has effective dates from 01-APR to 31-MAR for 2013, 2014 and 2015. One BPA is defined for Supplier A, which was originally set to Rank 1 with 100% allocation. A new BPA was created for the same item and with same effective dates as the current BPA. The BPA is for a different Supplier. When Generate Sourcing Rules is run it adds the new BPA/Supplier to the Sourcing rule, but its added as Rank 1, with the old rule changed to Rank 2. For complete information refer to  Doc ID 1678447.1 Generate Sourcing Rules And ASLs From Blanket Agreements Ranking not Behaving As Expected. Still have Questions? Access the Procurement Community and, using the 'Start a Discussion' link, post your question.

• Creating an OpenGL FPS camera: I have the position and orientation vectors, now what?

  - by Synthetix

  I have been struggling to create a first person camera in OpenGL ES 2.0 without using gluLookAt(). I grab the camera's orientation vectors (the way it's looking) from the current modelview matrix, and use that to calculate the new forward/backward (Z) translation value. I then calculate the strafe (X) value from the dot product of Z and Y (which is always 1.0). So, I have all the information I need to create a view matrix, but how do I do that without using gluLookAt? Almost all the examples I've seen use gluLookAt, but no such function exists in OpenGL ES 2.0. Besides, one of the moderators on cprogramming.com mentioned that gluLookAt is not appropriate for FPS cameras: http://cboard.cprogramming.com/game-programming/135390-how-properly-move-strafe-yaw-pitch-camera-opengl-glut-using-glulookat.html I am really confused by all the conflicting information I'm getting. I just want to create a first person camera that goes forward (W,S keys), side-to-side (A,D keys) and rotates around its center (Y axis only), Wolfenstein style. Any help on this would be much appreciated!

• Can I properly use NS2 on latest Ubuntu 12.04?

  - by Nwe Nwe

  I am a novice user for Ubuntu because I need to work with NS2. NS2 properly work only in Linux, Ubuntu. Now, I wonder if it can properly work on latest version Ubuntu. My current window is Window7. I also want to use Window7. So, which one will be better on parallel booting of Window 7 and Ubuntu or using VMWare on Window7 to install Ubuntu. My RAM is 4G. My processor speed is 1.6G. If I use VMWare, my C drive is only extra 10G. So, does VMWare can work properly in D drive? Please let me know which way is the best for my situation. I hope the advice from anyone. Thanks in advance.

• Acer sound card

  - by Rob Brugh

  Hi I have an acer aspire on a recent upgrade somehow it loaded dummy output into upper memory so every time I boot up I have to manually load my sound card. using sudo /sbin/alsa reload then alsamixer and f6 to change to my proper sound card. How do I go about making that my default sound card loading on boot every time. sometimes the message comes up cannot find alsamixer, if that happens I have to run the following command sudo /sbin/alsa force-reload and then alsamixer. That works only on current session I would like to get that so it boots without coming up with dummy output. anyone out there know what the command is to make that load to boot section?

• How can I acheive a smooth 2D lighting effect?

  - by Cyral

  I'm making a tile based game in XNA. So currently my lightning looks like this: How can I get it to look like this? Instead of each block having its own tint, it has a smooth overlay. I'm assuming some sort of shader, and to tell it the lighting and blur it some how. But im not an expert with shaders. My current lighting calculates the light, and then passes it to a spritebatch and draws with a color parameter. EDIT: No longer uses spritebatch tint, I was testing and now pass parameters to set the light values. But still looking for a way to smooth it.

• Rewriting software using Agile methodologies

  - by Asier

  Suppose you have to rewrite an entire application using Agile methodologies, how would you do it? I guess you could write a big bunch of user stories based in the behavior of your current system. And then implement them in small iterations. But this wouldn't mean that we have the requirements UP FRONT?? Also, when would you start releasing? Agile says we should release early and often, but it doesn't make much sense to release before the complete rewrite has been completed. Anybody has used Agile before to rewrite software? How did you do it?
