• How can you plan long range resources and budgets when using Agile methodology?

  - by Mystere Man

  Agile does not encourage a lot of up-front design. This is good from a requirements management and software development standpoint, and allows the project to adapt to changing business needs. However, how does one do any long range planning of resources if you don't really know what you're going to build when you start? Oh sure, you have a conceptual model of what you're going to build, but you don't have any measurable detail from which to gague how many resources you will need to complete the project, or how much it will cost. Does anyone have any suggestions on how to go about long range planning in an agile environment?

• How much code do you write everyday, *at work*?

  - by Aerovistae

  I'm graduating college, about to start a junior software engineering position, and I've been wondering how much I'm going to be expected to do on what kind of timeline. I mean, in python I can write maybe 500 lines in 8 hours. In C, maybe 200 lines in 8 hours. And that's a big maybe. (I'm f#$*ing terrible with C.) Other languages are somewhere in between. I don't even know if that's ridiculously slow or normal or even good, hence the question. How much code do you write a day? It would be helpful to specify what language/technology you're using, and to make note if there are big differences between them like with myself.

• Is there a name for this use of the State design pattern?

  - by Chris C

  I'm looking to see if there is a particular name for this style of programming a certain kind of behavior into a program. Said program runs in real time, in an update loop, and the program uses the State design pattern to do some work, but it's the specific way it does the work that I want to know about. Here's how it's used. - Object Foo constructed, with concrete StateA object in it - First loop runs --- Foo.Run function calls StateA.Bar --- in StateA.Bar replace Foo's state to StateB - Second loop runs --- Foo.Run calls StateB.Bar - Third loop runs --- Foo.Run calls StateB.Bar - Fourth loop --- etc. So in short, Foo doesn't have an explicit Initialize function. It will just have Run, but Run will do something unique in the first frame to initialize something for Foo and then replace it with a different action that will repeat in all the frames following it- thus not needing to check if Foo's already initialized. It's just a "press start and go" action. What would you call implementing this type of behavior?

• Disabled WiFi but it keeps re-enabling itself; want it to stay disabled

  - by Mike Uresti

  I have an Alienware X51 desktop with a wireless card, I have it connected via ethernet and want to permanently disable WiFi from ever using itself. When running Windows, I go to device manager and rightclick-disable the Wireless card and that takes care of my problem. Is there a similar method using Ubuntu 14.04? For now, I click on the network icon in the system tray and uncheck 'Enable wifi' but it seems to turn itself back on as I use my computer, I think I have the incident isolated to something with Steam. It seems like after I start the Steam client it always is re-enabled. Hopeful answer: Just disable/remove/block wireless card from ever working.

• Using cracked software and tools [closed]

  - by Lena Aslo

  I am seeing people complaining about expensive tools such as Dreamweaver or Photoshop. I am just wondering about that, because everyone knows that they can get this software running for free (if it is done illegally). Why don't they just use a cracked version? Is it so likely to get caught? I feel that nowadays a lot of people are using cracked software but whenever the topic is mentioned, they ALL say PSSST!!! or start criticizing it, even though they are doing it themselves...

• Truecrypted Windows 7 missing in Grub2 after upgrade

  - by user287545

  I have an encrypted dual boot Windows 7/Ubuntu System and upgraded my Ubuntu today. Everything went smooth but my Windows is not shown in the Grub2-List anymore. Starting up I have the Truecrypt Bootloader and after entering the Password I get to Grub (now Grub2). There my Windows 7 entry is missing now. Here is my report: http://paste.ubuntu.com/7569182/ Updating Grub did nothing to it. My guess is that within Ubuntu it does not recognize my Windows Installation on sda1 anymore. I can't mount it aswell. I can only mount it via Truecrypt itself. I think I might have to manually insert the menu item for Windows into that Grub config file. I guess that after entering the password in the truecrypt bootloader it would be possible to start Windows if the item was there - just a guess though. Edit: I basically followed these steps to set up my system: Dual Booting Windows 7 with Ubuntu 12.04LTS with Truecrypt

• Update live USB distro?

  - by qubex

  I have Lubuntu 14.04 (and Ubuntu 14.04) on a pair of USB disks created by writing the img files to USB using dd on Mac OS X. Unfortunately these systems both have some known bugs (that have since been corrected) and lack certain important drivers for my system (which I have located online). How can I make the USB disks writable and how do I update the distribution upon them as one may do for a locally-installed system? And if I later proceed to install from these USB sticks onto a hard-drive, will they ‘carry’ the package and driver updates with them or will I have to start from scratch again? (I seem to remember from my ancient Windows XP days that such procedures were referred to as ’slipstreaming’ or somesuch on that side of the fence.) (No, I did not create a persistence partition when I created the sticks, because from Mac clearly that isn’t an option. And anyway, as I imperfectly understand it, the persistence partition is for user files and not for the modification of the system.)

• Skype 4.2 crashes and bugs on 13.10

  - by Juhani Taylor

  I've installed Skype and it appears to work fine right up until the point where I try to call someone. If I try to video call someone then the programme freezes and I have to force quit. I've tried several 'solutions' I've found on various forums but none seem to work. Now, when I try to call the Echo service as a test to see if the bug's fixed, it seems to connect and start the non-video call, except that it's completely silent. No audio at all. Any help? It seems to be 2 separate issues: audio and generic crashing. Anyone come across these and found solutions?

• Chrome keeps crashing after updates

  - by Phil

  I'm a chrome user and an enthusiast but few days ago I made Ubuntu get some updates using Update Manager, then I turned off my notebook and when I restarted it, I tried to start Chrome which after a few seconds turned the screen completely black, and some errors appeared for few seconds and then I got logged off, and had to re-login, and when I opened Chrome again the same thing happened! I've uninstalled it with Synaptic and did complete cleanings before re-installing Chrome but nothing succeeded. Now I can't use either Chromium and Chrome, but Firefox works. It's a very strange thing, never happened to me before and I don't know what to do because I had all my bookmarks syncronized in Chrome! Please help if you can :)

• New hard drive means re-install everything

  I recently found a good deal on a 7200 RPM 500GB latpop drive and decided to upgrade myself to that. Ive been operating on a 150GB drive for a long time and hadnt been cleaning up old projects, encodings, etc. so it was running thin on space. This was a cheap upgrade (< $90) so I opted for it. I finally got a moment last evening to pop it in and start the fresh installs of everything. Doing so reminded me of how long this process takes for us geeky people. Luckily I do a backup first using my...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• What options should I consider for a modern Web/Mobile development stack? [on hold]

  - by jimmy_terra

  I'm a long time server side dev who has been tasked with building a bleeding edge web UI (go figure), so apologies for the very broad nature of the question. What are the best modern libraries, tools, languages and patterns for building a dynamic web application that will run seamlessly on mobiles also? My requirements are that it must be dynamic (push updates), support automated testing, and should allow 'componentization' (a team of devs will be working on this). What should I check out and why? I will start off with some of the things I'm looking at already: Front-end HTML5 CSS3 JavaScript AngularJs Testing Karma Testem Jasmine Patterns Single Page Applications

• sudo does not work in GUI after upgrade to 13.10

  - by Radim

  On 2 completely different machines I have the same problem after upgrading from 13.04 to 13.10: All programs/task requiering sudo permissions (software updater, starting synaptic, installing programs, shutdown) do not start / execute. No gksu (or other) window comes up. Synaptic never shows, software updater pops up with a "you are not allowed to perform this action" message. All programs / task work when started from terminal with sudo, like "sudo synaptics" asks for my password, starts and works as expected. I am in the admin group which is liked in sudoers config (verified with visudo and getent group admin). Some link from GUI to gksu (or similar) is broken. Please help! Radim

• Recommend an open source CMS for single page web site

  - by RedMan

  Hi I want to create a single page web site like http://kiskolabs.com/ or http://www.carat.se to display my portfolio. I want to add new products after launching the site without having to edit the entire site. I've looked at opencart (too much for single page site), Magneto (more for ecommerce), Wordpress (couldn't find open source / free templates which i can start from). Can you suggest a CMS which will support the creation of a single page site and allow insertion of new products without having to edit the entire page? I would prefer a CMS which also has open source / free templates which I can tweak for my use. I can do php and mysql, xml. If it is an easier option I can do PSD to site (but don't know much about this at all).

• ISO Live Session from an External Hard Drive?

  - by amemus

  Is it possible to use an external hard drive to start a live Ubuntu session? Is having an ISO file as the whole content of the first partition of the device enough? Thank you for reading...! EDIT upon reading the first comment to my original question: If I remember correctly, I COULD run a live session of Oneiric Ocelot somehow. It was not from a CD because I failed to burn one, so it must have been from an ISO file. Still very very confused....

• Roll Your Own Flexi-Ties to Secure and Store Frequently Used Cables

  - by Jason Fitzpatrick

  If you’re looking for an easy way to hang up or tidy frequently used cables, these DIY soft ties are durable, resuable, and easy to make. Soft ties ties are metal wire ties coated in rubber; people use them for everything from securing computer cables to shaping garden plants. Instructables user Bobzjr wanted a lot of them but couldn’t find anyone that sold bulk roles of the soft tie material. To that end he did a little exploring at the hardware store and found the perfect combination of wire and rubber to roll his own.

• Chromium web-app creation doesn't work in 12.10?

  - by speter

  If you create an application of a website in Chromium and choose "desktop", a .desktop file is created. In 12.04, you were able to move it to ~/,local/share/applications/ and then start it from the Dash or the launcher. In my fresh 12.10 installation, this doesn't work anymore. I think the line that is misinterpreted is Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/. If you try to run it from a terminal, you get the following result: 20:32 ~ speter Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/ bash: --app=http://buymeapie.com/: Datei oder Verzeichnis nicht gefunden (English: "File or directory not found"). Can anyone explain or knows a workaround?

• TDD, new tests while old ones not implemented yet

  - by liori

  I am experimenting with test-driven development, and I found that I often come to a following situation: I write tests for some functionality X. Those tests fail. While trying to implement X, I see that I need to implement some feature Y in a lower layer of my code. So... I write tests for Y. Now both tests for X and Y fail. Once I had 4 features in different layers of code being worked on at the same time, and I was losing my focus on what I am actually doing (too many tests failing at the same time). I think I could solve this by putting more effort into planning my tasks even before I start writing tests. But in some cases I didn't know that I will need to go deeper, because e.g. I didn't know the API of lower layer very well. What should I do in such cases? Does TDD have any recommendations?

• Deforming surfaces

  - by Constantin

  I try to accomplish an deforming physic behaviour for levelsurfaces, but don't get an idea how to start with the implemenation so far. Regardless of the shape from the surface (planes, cubes, spheres…), I want to have small indentations at the positions from game-entitys (players, enemys, objects…). It's kind of complicated to explain, so I illustrated what I'm talking about (here is an example with an sphere): So, the surfaces should be able to deforming themselfs a little bit (to apear like an really soft bed or sofa). My surfaces need probably an high vertices count to get an smooth deforming, but my big problem is the math for calculating this deforming… I'm programming in C/C++ with OpenGL, but will be fine with any advices in the right direction. Any help would be highly appreciated,

• Auto backup mysql database to dropbox [closed]

  - by Rob

  Is it possible to automatically backup my database to dropbox? If so how can I do it? The key criteria I need it to do is: Be automatic. Be Mac compliant. Be weekly. Sync with dropbox (http://www.dropbox.com) automatically. Be able to backup several databases from several websites. Be free... or relatively cheap! Have a guide on how to setup the solution. UPDATE: I've managed to setup an auto weekly backup using a cronjob: mysqldump -u username -pMyPassword Mydatabase > backup-file.sql That is saving the backup to my hosting space. It's a start but isn't ideal, how can I save that backup to a folder on my computer? Automatically of course.

• Twitter Customer Sentiment Analysis

  - by Liam McLennan

  The breakable toy that I am currently working on is a twitter customer sentiment analyser. It scrapes twitter for tweets relating to a particular organisation, applies a machine learning algorithm to determine if the content of tweet is positive or negative, and generates reports of the sentiment data over time, correlated to dates, events and news feeds. I’m having lots of fun building this, but I would also like to learn if there is a market for quantified sentiment data. So that I can start to show people what I have in mind I have created a mockup of the simplest and most important report. It shows customer sentiment over time, with important events highlighted. As the user moves their mouse to the right (forward in time) the source data area scrolls up to display the tweets from that time. The tweets are colour coded based on sentiment rating. After I started working on this project I discovered that a team of students have already built something similar. It is a lot of fun to enter your employers name and see what it says.

• Part-time work as a beginner programmer [on hold]

  - by Valentas

  I wrote to one company near my university (starting in September) and they responded that they will probably hire me from the work I have already done (some projects and Euler problems solving). It's for 15 hours/week or so in order to not fall behind uni work. They require Python, SQL, XML and a good idea about how the Web works. The job role involves acquiring data from the Web and supplying it as search results for flight seekers (people). I am eager to learn but still, what can I do to become prepared for this? I ask because I tend to gravitate from one technology to the other, trying out things but never mastering it properly. What Web technologies are involved in such a job role? I have two months and want to learn as much as possible because there is much info but I have no idea where to start.

  Say for example I have a website that has finished BETA and is ready for full launch. I'm at the stage now I want it to be very visible to start getting traffic. Right now, I am just getting some random search engine hits, word of mouth and a few referrals. How do I break out of this and really get some serious traffic to my site? Do I need to launch a huge ad-campaign? If so, what is the best/most cost effective way to do this? I have tried google adwords but at $0.45+ a click this jsut isn't practical for what I have.

• after login, the desktop remains blank.

  - by MobileDev123

  Hi, I have installed Ubuntu 10 last night and finished all upgrading stuff, in the time when updates are applied I downloaded a torrent file. As soon as download is finished I rebooted my system. As usual at start up it asked my login and I did the same. After a successful login It should show me the desktop, or show an error message in case anything has gone wrong. But what I had is only a cursor and a blank wall paper. Can anybody tell me what is the problem and how to resolve this? Thanks
