• Ubuntu upgrade deleted my email accounts

  - by Johnt

  I'm a long term Ubuntu user and until today I have been really happy. I've always run Evolution and Thunderbird and after Ubuntu apparently upgraded me from 11.04 to 11.10 both my Evolution and Thunderbird programmes and all data / address books, messages and folders were deleted and I now have to create new accounts for both programmes. All my previous data is LOST. Thanks a lot guys. Why did this happen and why was there no warning given that this could be an issue ??? Is any of this recoverable ?

• Visual Studio 2010: Custom Start Page

  - by Steve Clements

  As Visual Studio 2010 IDE has been mostly written in WPF, extending the start page has become pretty darn easy and I for one find this quite interesting as I always open with the start page and the more customisation I can have the better! There are a few things you will need to install first to get going Visual Studio 2010 SDK Start page project template, which you can either get from the New Project dialog, in the online gallery section in VS or download from here   I was going to write a blog post on how to create a custom start page, but decided that msdn have done such a good job I was pretty much wasting my time, so take a look here, it has in detail everything you need to know to get it done! :) Technorati Tags: Visual Studio 2010,Custom Start Pages

• Perl numerical sorting: how to ignore leading alpha character [migrated]

  - by Luke Sheppard

  I have a 1,660 row array like this: ... H00504 H00085 H00181 H00500 H00103 H00007 H00890 H08793 H94316 H00217 ... And the leading character never changes. It is always "H" then five digits. But when I do what I believe is a numerical sort in Perl, I'm getting strange results. Some segments are sorted in order, but then a different segment starts up. Here is a segment after sorting: ... H01578 H01579 H01580 H01581 H01582 H01583 H01584 H00536 H00537 H00538 H01585 H01586 H01587 H01588 H01589 H01590 ... What I'm trying is this: my @sorted_array = sort {$a <=> $b} @raw_array; But obviously it is not working. Anyone know why?

• 24 Hours of PASS: 15 Powerful Dynamic Management Objects - Deck and Demos

  - by Adam Machanic

  Thank you to everyone who attended today's 24 Hours of PASS webcast on Dynamic Management Objects! I was shocked, awed, and somewhat scared when I saw the attendee number peak at over 800. I really appreciate your taking time out of your day to listen to me talk. It's always interesting presenting to people I can't see or hear, so I relied on Twitter for a form of nearly real-time feedback. I would like to especially thank everyone who left me tweets both during and after the presentation. Your feedback...(read more)

• DBMS agnostic - What to name the COUNT column from a SQL Query

  - by cyberkiwi

  I have trouble naming the COUNT() column from SQL queries and will swap between various variants _Count [Count] (sql, or "count" or backticks for MySQL etc) C Cnt CountSomething (where "something" is the field being counted, or "CountAll") NoOfRows RowCount etc Has anyone come up with any name that you are happy with and always use without hesitation? This is bothering me because after joining SO just recently, my answers have shown this tendency of flip-flopping with no consistency. I need to get this sorted. Please help. (While we're at it, what do you use for SUM etc?) Note: Before you close this question, consider that this one was not: What's the best name for a non-mutating “add” method on an immutable collection?

• Will small random dynamic snippets break caching

  - by Saif Bechan

  I am busy writing a WordPress plugin. Now most users have cache plugins installed, they cache the pages. I know also some webservers as nginx have php caching and whatnot. There are also things like memcached. Now I have to admit I do not know exactly how they work, if anyone have some good links on how they work I would be glad. Some links where it's explained simple, not to technical. Now the question. My plugin displays different statistics on posts, they are always different, will this break the caching of the page. To take is a step further, sometimes the statistics of the post needs updating, and there is a small javascript snippet added to the page. Now will these two action result in the page not caching, or am I ok.

• Making a game "resize-safe"

  - by CPP_Person

  It's one thing to get the graphics aligned perfectly, it's another to do this for every single resolution and not take too much time and/or make the code unreadable due to size. Games like Battlefield 3 and Minecraft seem to manage this. But what do they do to keep things from stretching or going off the screen? I don't know any algorithms to do this. I'd like some help on this topic. I've always programmed games that only handle a single resolution, so help would be appreciate.

• Do you know that every user story should have an owner?

  - by Martin Hinshelwood

  When you are building complicated software and working with customers it is always nice for them to have some idea on who to speak to about a particular story during a sprint. In order to achieve this one of the Team takes responsibility for “looking after” a story. They will collect all of the “Done” emails and make sure that everyone follows the Done criteria identified by the team as well as answering any Product Owner queries. Figure: Bad example, The product owner is not sure who to speak to. Figure: Good example, The product owner can now see who he should speak to an developers know where to send done emails.   Technorati Tags: SSW,Scrum,SSW Rules,Rules to better Scrum with TFS

• Is online freelance work viable by American standards?

  - by JoelFan

  I've always been curious about trying out online freelance sites... it would be nice to work from home, feel independent, get to choose what I want to work on, get to work on different technologies, lose the PHB, etc. However I never really gave them a chance because I'm used to American rates and assumed that I would be competing with people from India, Russia, China, etc. that would severely undercut me, and it wouldn't be viable for me. Am I correct in this assumption or should I give it a shot? What kind of hourly rate would I be able to expect on short-term programming work?

• Making organic 2D tilemaps for tile based games...

  - by Codejoy

  So I have always wondered how one makes a nice (not so squarish) 2d tile map, is it possible? all games now days I think use textured polygons...but my game engine (and engine) doesn't support that to my knowledge. But it does support nice TMX files generated by mapeditor.org's Tiled Map Editor. Though in my game I want nice twisting and turning caverns to traverse ... I was wondering some ideas on such a process... is it in the art style? The type of tile engine? both? So what are some common techniques?

• Visual Studio 2010: Fun with extensions

  - by BizTalk Visionary

  One of the powerful things that has come into Visual Studio over the last few years has been joy of extensions. With 2010 there seems to be even more!! Of course teaching old dogs like myself new tricks always takes time but interestingly enough some of the rules I learnt early in my working life over 30 years ago still hold true!! A derivation of one that was knocked into during my engineering apprenticeship and associated exams was RTFQ! Read the ‘flippin’ question. (I replaced the original ‘F’ with a more palatable version here!). Today I forgot that rule and didn’t RTFI (I being instructions) and spent a fruitless hour wondering why my Entity Framework POCO generator never appeared in the new project template list when I wanted to add it!! It was simple of course – I had only installed the Entity Framework POCO generator for web sites and not building a web project meant it would never appear!!! A quick look again I found the ‘other’ extension that supported my project type! So RTFI!!

• MTP Won't Work With Newer Ubuntu

  - by spacesword

  I have a Philips GoGear Vibe 4 GB, set to MTP mode, as it's always been. This works fine with older versions of Ubuntu and works fine with Windows, but doesn't work with newer versions of Ubuntu. The version history is like this: 12.04 - works 12.10 - works 13.04 - doesn't work 14.04 - doesn't work Windows 7 - works When you plug the MP3 player in Ubuntu the file manager opens the root of the device, which contains the folder "internal storage". When you click on "internal storage" to open it, the file manager just hangs. And if you try to unmount the MP3 player, that process hangs too, until you just unplug it. In Windows when you click on internal storage, it opens and shows all the files it contains. And in the earlier versions of Ubuntu it just worked. Any ideas? Thanks.

• Auto-mount CD/DVD drive to single, specific mount point every time?

  - by Christopher Parker

  Currently, whenever I insert a CD or DVD into my DVD drive, it mounts to a location such as /media/<LABEL>, where <LABEL> is the arbitrary label assigned to the optical disc. I remember, once upon a time, CD and DVD media being reliably located at /media/cdrom0 or something similar. Why was this changed? And how do I get this old behavior back for this drive? I can understand this behavior for USB sticks. It makes sense for those. But not for CD/DVD media, in my opinion. For example, because of this, I have no way to configure Wine to point to my DVD drive, as the mount point changes with every single CD I insert. TL;DR: How do I make CD/DVD media always mount to /media/cdrom0?

• Does a prose to code compiler exist?

  - by Raynos

  I have seen some horrible code in my time including people virtually duplicating the code in comments // add 4 to x x+=4; // for each i in 0 to 9 for (int i = 0; i < 10; i++) { // multiply x by i x *= i; } Taking this concept further, I'm curious whether prose to code compilers exist. Is there a valid use case for English prose to code? Do compilers exist that do this? The distinction between this and auto generated code, is that auto generated code is generally always a subset of a project. Can we have complete projects auto generated from english prose? I realise that this might overlap with the concept of declarative languages.

• Why do large IT projects tend to fail or have big cost/schedule overruns?

  - by Pratik

  I always read about large scale transformation or integration project that are total or almost total disaster. Even if they somehow manage to succeed the cost and schedule blow out is enormous. What is the real reason behind large projects being more prone to failure. Can agile be used in these sort of projects or traditional approach is still the best. One example from Australia is the Queensland Payroll project where they changed test success criteria to deliver the project. See some more failed projects in this SO question Have you got any personal experience to share?

• Oracle Keeps Growing Partner Certifications with Addition of McAfee

  - by Ted Davis

  Viruses stink. Whether it’s the common cold virus, Goatpox virus – yes it exists -- or a computer virus, you name it, viruses stink. When it comes to our computer server infrastructure we all want to make sure our servers are secure from any malware out there. Additionally, installation of anti-virus software is a requirement by many governments and for many enterprises both large and small. Because of the growth of Oracle Linux in their customer base, McAfee recently certified their “McAfee VirusScan Enterprise for Linux” on Oracle Linux.  It delivers always-on, real-time anti-virus protection for Linux environments. Its unique, Linux-based on-access scanner constantly monitors the system for potential attacks. While there have been few viruses found on Linux, you can now feel secure running Oracle Linux in your infrastructure with McAfee on top. We are happy to introduce McAfee into the Oracle Linux family of certified applications.

• Trying to implement fling events on an object

• Checker AI in visual basic not working [on hold]

  - by Eugene Galkine

  I am trying to a make checkers in visual basic with ai. I am using the minimax algorithm (or at least what I understand of it) and it works, except the ai is retarded and plays like it is trying to loose and I tried to switch around the min and the max but the results are IDENTICAL. I am pissed of and have been trying to fix it for over a week now, I would really appreciate it if someone could help me out here. I have 3 years experience of programming (in Java, only about of month of VB experience) and I always am able to solve all my errors on my own so I don't know why I can't get this to work. The program is not at all optimized or anything at this point and is over 1.2K lines long, so here is the entire vb project instead: https://www.dropbox.com/sh/evii0jendn93ir2/9fntwH2dNW I would really appreciate any help I could get.

• History of open source software

  I've been always interested, out of the pure self-amusement, in the history of open software used today: who were the people which started it and what were the reasons to start what were design decisions at the start how software evolved over the time Specifically, I'm interested in following software: GCC X Linux kernel Java Of course, there is plenty of information in Internet to google for, but I thought it would be nice to have list of interesting resources at this site. I hope some of visitors of this site have similar interest and can share a link or two they found particularly amusing/interesting. To make this entry more question-like, here's straight question: what are the most interesting/amusing links about history of open source software?

• Wrong audio volume at boot

  - by skerit

  When I boot my computer and login the volume level is always way too loud. Unfortunately the only way to change it is a physical knob on my speaker. As soon as I can change the volume using my keyboard the volume immediately drops. Say the volume is at 100%, as soon as I turn the dial on my keyboard a little bit it drops to a normal level like 40% How do I get this to work in a clear way, like having it remember the audio level it was on at shutdown? Here's my audio card model: 82801JI (ICH10 Family) HD Audio Controller An Intel card on a Asus motherboard
