• Release roadmap with scrum

  - by SyBer

  I need to prepare an internal product release road-map for product being built via scrum methodology, and have some difficulty correlating sprints to the road-map. The main problem is that as I don't have effort estimations for every story, because these prepared immediately before each sprint, so I don't know what will make into which sprint. I'm fine with changing the road-map as the development goes on, but need it to give at least some indication when things planned to be released. So what would be the best way to do this, other then guestimating the whole backlog? Thanks for any idea.

• Issues with HP Mini 110-1125NR

  - by Guga Figueiredo

  Just finished installing Ubuntu 12.04 Precise Pangolin on my HP Mini 110-1125NR and im having small, but rather irritating issues. I installed it over the Windows 7 (starter) which came with the netbook. Firstly, it will only boot from the USB flashdisk. If i try to boot from the hardrive, it goes to a black screen. Second, built-in wireless wont activate. system says its enabled and on, but the light indicator is still orange (as if its off), and i cant get a signal from my home wi-fi I havent found any solved threads for inspiration, and mos of them are pretty old (1 year +) so i thought of giving a try to see if any of you guys System is: HP Mini 110-1100 1gb memory Intel Atom CPU N270 @ 1.60GHz x 2 Os - Precise Pangolin - Ubuntu 12.04 160gb Hard disk If any of you are aware of the solutions of my issues it'd be awesome Thanks in advance for any help!

• Accidentally deleted my windows 7 while installing ubuntu, trying to reinstall it

  - by user286874

  I had Windows 7 Ultimate on my desktop and I believe have downloaded the correct ISO file. I've been trying to use GParted and UNetbootin to create a bootable usb by formatting to FAT32, flagging the boot box, and writing to the flash drive with UNetbootin, but there have been problems. When I select my flash drive in the BIOS, it just reflashes the BIOS stock MSI picture 4 times then boots to Ubuntu anyway. Details: it's a new computer, self-built, hasn't shown any problems in the past, got Windows 7 through r/softwareswap so it's a MSDN file, the flash drive is a Sandisk U3 Cruzer, I uninstalled the bloatware when Iwas using Windows 7, but in the BIOS it still comes up as "Sandisk U3 Cruzer" I don't have a cCD/DVD drive. I dont care if I have to completely delete ubuntu in the process, I just need Windows 7 back by monday. I think the problem is because of the cruzer and am going to pick up a different flash drive today.

• Web programming, standard way to deal with a response that takes time to complete

  - by wobbily_col

  With normal form submission I use the pattern Post / Redirect / Get, when processing the forms. I have a database application built with Django. I want to allow the users to select a number of items from the database, then launch a computationally intensive task based on those items. I expect the task to take between 10 minutes and 2 hours to complete. Is there a standard approach to dealing with requests like this (i.e. that don't return immediately)? Ideally there would be some way to display the progress.

• What to use for an event listing site? [on hold]

  - by Vykintas

  I have a site which lets users buy & sell tickets, but it's built on wordpress & buddypress. So it's very heavy and messy. I would like to re-do the whole site on something lighter, cleaner and solid. The main functionality for user would have to be as follows: Register or login via Facebook. Create events and sell tickets to them. See ticket sales statistics Upload photos and associate those with events. Buy event tickets, print pdf ticket. Comment, favourite and like events. What would be your suggestions? PHP framework? CMS? CMF? I must say that I'm a front-end dev so building a system from scratch on my own would take a while. I'd be interested more in a "skeleton" app solution or something similar.

• Severe graphics and application problems after update

  - by jenald

  I wanted to upgrade from 11.10 to 12.04 with the built-in upgrade-feature. but during the upgrade my pc stopped working. When I restarted my PC Ubuntu starts OK, but with many errors (many apps don't work and some graphic-errors). I try to upgrade again to 12.04, but I can't, because my Ubuntu identifies itself as 12.04. I tried to upgrade with the cd-setup but this also doesn't work. What should I do, if I don't want to reinstall the whole system?

• Generic Handler vs Direct Reference

  - by JNF

  In a project where I'm working on the data access layer I'm trying to make a decision how to send data and objects to the next layer (and programmer). Is it better to tell him to reference my dll, OR should I build a generic handler and let him take the objects from there (i.e. json format) If I understand correctly, In case of 2. he would have to handle the objects on his own, whereas in case 1. he will have the entities I've built. Note: It is very probable that other people would need to take the same data, though, we're not up to that yet. Same question here - should I make it into a webservice, or have them access the handler?

• Ubuntu 12.04 - Read only file system+computer crash/freezes after an update that got interupted

  - by user288542

  I've run into an error with Ubuntu while I was updating it. During the update my power went out and interrupted the update. When I finally got power and booted my computer, I received an error, telling me to remount ./ and basically told me I could press S to skip or F to fix. (I forgot exactly what it said) but anyways, I originally pressed F to fix, but that didn't solve the problem, so then I went into the terminal and I tried to remount that way, but I couldn't execute because it's stuck in "file system read only." Sorry, my description of the problem is dull. I'm debating on just reinstalling, but I have a ton of files I would like to keep, about 3+ years worth of websites I've built. Is there a proper way to fix this?

• Data structure for file search

  - by poly

  I've asked this question before and I got a few answers/idea, but I'm not sure how to implement them. I'm building a telecom messaging solution. Currently, I'm using a database to save my transaction/messages for the network stack I've built, and as you know it's slower than using a data structure (hash, linkedlist, etc...). My problem is that the data can be really huge, and it won't fit in the memory. I was thinking of saving the records in a file and the a key and line number in a hash, then if I want to access some record then I can get the line number from the hash, and get it from the file. I don't know how efficient is this; I think the database is doing a way better job than this on my behalf. Please share whatever you have in mind.

• sometimes, strange audio distortion(peeping, scratching), ubuntu 12.04

  - by richi902

  i have a problem with my sound in ubuntu 12.04. the problem is, that sometimes out of nowhere, when switching songs, or playing youtube videos, changing volume with my keyboard buttons, that the sound gets distorted(peeping, scratching). i dont know if it is related, but when i skip through music in rythmbox, there is also a little scratching noise. i can sometimes temporarly fix it: for youtube videos, i refresh the page, and sometimes it works agian normal, mostly not. for audio playback with rythmbox, i have to pause the song for sometime, and resume it, and hope that it works. before all that,i have changed my soundcard to "Analog Surround 5.1" in the sound settings from ubuntu, but i also used alsamixer to change it from 2 channels to 6 channels, since changing in ubuntu sound settings alone wasnt enough to make the other speaks work. i use a ASUS P8-H61-M LE B3 Revision Motherboard. which has a built in surround soundcard.

• Actinic and Google Analytics: does it mess with my stats?

  - by tjcss

  My fathers website is built using Actinic - not by me but by a local company - and since he went with them some years ago his traffic never went down, but has stayed more or less consistent which is fine. My question is this; does using actinic somehow confuse analytics? As it shows that 99% of all visitors come "direct", as in, not by organic search. Previous to using Actinic he would get 70 to 85% of new hits exclusively from organic search terms. So I'm wondering if Actinic somehow messes with these new hits and redirects them to a "home" page.. Not sure exactly what I mean but this change in stats is concerning and I'm struggling to find an explanation.

• What is Rails way to save images?

  - by user

  I develop on iOS, and I'm switching from a PHP backend to Ruby on Rails. The interchange format is JSON. A quick Google search for 'save images in Rails' has nearly every result talking about saving image data as blobs to the database. I might be mistaken, but I'm under the impression that saving image data in a database is a huge waste of time and space (as opposed to saving a link to the file location ('/img/subcat/4656.png'). In PHP, it's pretty standard to receive the data, generate a filename, then save that file to disk, and then update the database with the image's location on disk. Is this the same for Rails, or is there some built-in ActiveRecord image functionality I'm not aware of?

• Collisions and Lists

  - by user50635

  I've run into an issue that breaks my collisions. Here's my method: Gather Input Project Rectangle Check for intersection and ispassable Update The update method is built on object_position * seconds_passed * velocity * speed. Input changes velocity and is normalized if 1. This method works well with just one object comparison, however I pass a list or a for loop to the collision detector and velocity gets changed back to a non zero when the list hits an object that passes the test and the object can pass through. Any solutions would be much appreciated. Side note is there a more proper way to simulate movement?

• 12.4 LTS after update fails to login

  - by user111839

  An update today (30-11-2012) on 12.4 lead to failure to log in. The system gets through its boot process then presents the logins, on choosing any of these immediately returned to log-in screen with no error. Machine is an AMD FX 64 on an Asus MB using the built-in graphics. If no one knows what this might be, what's the alternative distro to Ubuntu? It's the second time something like this has happened after an update in three months, kudos to the Ubuntu team but I need more reliability. Cheers, thanks to all.

• Would you see any use of a Trilean (True, False, ??)

  - by Sybiam

  I don't know if I'm alone but sometimes I have a function that should return true or false. But in some case there would be a third result that would make more sense. In some language theses cases would be handled with integers or with exception. For exemple you want to handle the age of a user if he is over 18 years old. And you have a function like this. if(user.isAdult(country_code)){ //Go On }else{ // Block access or do nothing } But in some case depending how your app is built I could see case where the birthday field is incomplete. Then this function should return something undetermined. switch(user.isAdult()){ case true: // go on break; case undetermined: //Inform user birthday is incomplete case false: //Block access } As i said we can handle that with Exceptions and Int, but I would find it quite sexy to have a true, false, undetermined embeded in the language instead of using some home defined constants.

• The underlying provider failed on Open

  - by aghausman12

  The underlying provider failed on Open is an entity framework error and with a simple fix it is little difficult to sort out what is going wrong. 1) if you are using IIS 7 with Integrated Security in connection string. Make sure your IIS user have appropriate permissions to access database. 2) If you are using Visual Studio built in Web Server and facing this issue. Simple fix is to either re-start Visual Studio or Kill the process of Web Server which is (WebDev.WebServer*.exe). I was in the second...(read more)

• Managing different utility classes between engine and libraries

  - by hayer

  I'm currently in updating some engine code (which does not work, so it is more like creating a engine). I've decided to swap over to SFML (instead of my own crappy renderer, window manager, and audio), Box2D (since I need physics, but have none), and some small utilities I've built myself. The problem is that each of the project mentioned over use different types for things like Vector2, etc. So to the question: is it a good idea to replace Box2D and SFML vectors with my own vector class (which is one of my better implementations)? My idea then was to have a separate .lib with all my classes that should be shared between all the projects in the solution.

• Is this the place to ask SEO questions [on hold]

  - by user39206

  I'm adding business listings to an existing website of which Google has sort of been referencing well but my Meta tags have a lot to be desired! Due to other work commitments I have kind of neglected the site but now think I should put the proper time and effort into getting it just right as it does earn me money. I am a developer so I have all the necessary skills to build the site, it's almost done!. Now I'm just a little worried that I could do something wrong and loose the rapport I've built up with Google in the past or be ban. Especially with the new tags I see like: <link rel=”publisher” href=”https://plus.google.com/[YOUR BUSINESS G+ PROFILE HERE]“/> Really I just want to know for now, is this the place to ask SEO question?

• Hosting a website with Windows Azure

  - by Rev

  I may be completely misunderstanding what Azure is but is it possible for me to host a basic website on Windows Azure? I have a site that I've built in HTML and CSS that I'd like to upload to Azure but I can't figure out any way to do this. The site claims I can use it for web hosting, but if I can't FTP then I'm not sure how to do this. Is there a simple tutorial somewhere? I couldn't find anything close to what I'm looking for through searching.

• Are my Google Analytics ( 2 domains 1 site) duplicated or unique?

  - by MarcDJay

  We have recently built a new website with a new domain to replace an old website, and on the advice of our IT guys and web dev team have pointed both oldaddress.com's & newaddress.com's a records to the new website. Now, they both share the same google analytics code (UA-12345-1) and as such we have two entries in the Google Analytics dashboard. The problem is I'm still fairly novice with GA and as the reports seem VERY similar (~25k pageviews for each domain), are these figures exclusively for that domain? For example: oldaddress.com 25,400 pageviews newaddress.com 25,600 pageviews Does this mean that in total for this website I have 51,000 pageviews. Hope this is clear enough but let me know if anything needs clarifying. Thanks.

• Unable to Install ubuntu onto a blank hard drive

  - by user287561

  I just built a pc and I am trying to install Ubuntu 14 onto it. I did the process in which you format the flash drive to be able to have Ubuntu 14 and install directly in BIOS. BIOS is set up to boot from the flash drive. Every time I try to do the install process, it will randomly reboot itself onto the motherboard BIOS menu. This loop constantly occurs and the only way I can use Ubuntu is to put the option of trying but not installing. HELP!
