• New Pluralsight app for Android will bring variable speed

  Usually, it is very interesting to compare the 'same' software applications and apps between various platforms, and the Pluralsight offline players are an outstanding example to have a closer look at. The original Silverlight desktop offline player, the iOS app of Pluralsight and the new HTML5 online player all have variable playback speed. Just the Android app doesn't. But not for long. A couple of days Pluralsight finally announced that their development department found a reliable solution to provide flexible speeds. For the brave ones among us, please have a look at the public beta they are offering on their blog article.  Please be aware of, that using any Pluralsight offline player requires to have a Plus subscription. Otherwise, you cannot use the application after all.

• Algorithmic Forecasting and Pattern Recognition

  - by Ryan King

  Say a user could enter project data into my software. Each project has 2 variables "size" and "work" and they're related but the relationship is not known. Is there a way to programmatically determine the relationship between the variables based on previous data and forecast the amount of work provided if only given the size of the project in the future? For Example, say the user had manually entered the following projects. Project 1 - Size:1, Work: 4 Project 2 - Size:2, Work: 7 Project 3 - Size:3, Work: 10 Project 4 - Size:4, Work: x What should I look into to be able to programmatically determine, that Work = Size*3+1 and therefor be able to say that x=13?

• what's best language to mate with Adobe Flex-based GUI for math crunching?

  - by gkdsp

  Hi, I'm not a software expert but need to outsource a web-based scientific GUI application, and I'm considering Adobe Flex. My math routines are currently in Javascript and C/C+. Having no experience with Flex, was hoping someone could help me understand what options are available for performing (preferably fast and efficient) CLIENT-side calculations. That is, can Flex interact with Javascript and/or C easily? If not, is actionscript or other language preferred? Downsides/tradeoffs? Need functions like LOG10, LN, SQRT, and would be nice to also have the error function (ERF) and complementary error function (ERFC), although I may be able to derive these last two from more basic functions if necessary. Thanks!

• How important is to sacrifice your free time for accomplishing goals? [closed]

  - by Darf Zon

  I was reading a book about XP programming and about agile teams. While I was reading, I saw this scenario. I've never worked with a development team (just in school). So I would like what do you opine on this situation: Your boss has asked you to deliver software in a time that can only be possible to meet the project team asking if you want to work overtime without pay. All team members have young children. Discuss whether it should accept this request from your boss or should persuade the team to give their time to the organization rather than their families. What could be significant factors in the decision? As a programmer, you are offered an upgrade as project manager, but his feeling is that you can have a more effective contribution in a technical role in one administrative. Write when you should accept that promotion. Somethimes, I sacrifice my free time for accomplishing hits at work, so it's very important to me to know your opinion base of your experience.

• Enterprise Architecture - Wikipedia

  - by pat.shepherd

  I was looking at the Wikipedia entry for EA and found this chart which does a great job showing the differences of ENTERPRISE Architecture vs. SOLUTION Architecture across several categories.  This really gets at the heart of a misconception many people have about what EA is and where it sits in the grand business –> technical detail continuum. The following image from the 2006 FEA Practice Guidance of US OMB sheds light on the relationship between enterprise architecture and segment(BPR) or Solution architectures. (From this figure and a bit of thinking[which?] one can see that software architecture is truly a solution architecture discipline, for example.) Enterprise architecture - Wikipedia, the free encyclopedia

• Dropbox indicator icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• Upgrade or replace a Wubi installation?

  - by Torben Gundtofte-Bruun

  I've got Windows 7 with Wubi 11.10 installed. I would like to upgrade to 12.04 but I'm not sure what the best path would be. I'm not skilled enough to use Ubuntu all the time, and my iPhone requires me to run some Windows version for the damn iTunes software. I would love to run Windows XP but I can't figure out how to install it via USB -- my computer has no cd drive. I'd like to run Windows XP and Wubi 12.04 on top of that. Or, perhaps, Ubuntu 12.04 natively and Windows XP alongside of that. So I guess I have 2 questions: (lazy) Should I upgrade my Wubi from inside Ubuntu, or should I remove Wubi 11.10 from within Windows and install a brand new Wubi 12.04? (proper) How can I install Windows XP and Ubuntu 12.04 alongside each other? Update: I am going to create a separate question post about the above #2 question... I realize it's wrong to ask two questions in one post when they are that different.

  - by user219350

  I have repeatedly convinced of the reliability of the XFS file system , and I was more than satisfied . I was happy with everything in Ubuntu 14.04 ( great software) , but there is a little "but !

Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRUB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings for GRUB, but have not found an acceptable option and have no desire to reinstall again Clover (Mavericks reboots 20 seconds - excellent!) So please help on the file system - how to convert from XFS to HFS+ journaled. Mavericks to saw it all synced on Mac. Thank you for the sensible answer and help! Originally in Russian.

• In centralized version control, is it always good to update often?

  - by janos

  Assuming that: You are in a team developing some software. Your team is using centralized version control in the development process. You are working on a new feature which will surely take several days to complete, and you won't be able to commit before that because it would break the build. Your team members commit something every day that affects some of the files you're working with for your fancy new feature. Since this is centralized version control, you will have to update your local checkout at some point: at least once right before committing the new feature. If you update only once right before your commit, then there might be a lot of conflicts due to the many other changes by your teammates, which could be a world of pain to resolve all at once. Or, you could update often, and even if there are a few conflicts to resolve day by day, it should be easier to do, little by little. Can we say that it is always a good idea to update often?

• Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers?

  - by Smarty Twiti

  I am trying to make my first app for sale, I would like to ask some questions for those who have already sold their software: Have you used a Framework/Lib whose LGPL License? if yes, what are the impressions of your customers? for example, if your customers/ competitors from the market reveal technology/secrets that you used in your solution (as LGPL requires that you make a Dynamic Link (.DLL) for your libs and you clearly tell the use of a Lib/Framework). Full story: For my project, I used a framework LGPL/commercial (Dual License) the second one it was too expensive (about 3000 USD) which pushed me to use LGPL however I still concerned. That is why I ask for advise and especially motivations.

  I'm developing a Multimedia Software for Kindergarten Kids. It introduce them to animals, Alphabets, Simple Math, Colors and it contain some simple games. Music is very crucial for my project and it is very important to choose the right sort of music for different sections. But unfortunately I know nothing about music. Is there a music consultant firm which can help me to choose melodies and rythmes for my project from free music available in internet. My Budget is limited but as this is mandatory and I have no knowledge or taste about music, I think I can afford to pay for this.

• Installing Ubuntu on btrfs over multiple drives

  - by Tom Ato

  When I installed Ubuntu 13.04, I managed to combine a couple of outdated askubuntu answers, as well as some of the btrfs documentation in order to figure out how to install Ubuntu over two SSDs using a single btrfs partition (I think /boot was on a small ext4 partition). I want to install Ubuntu 13.10 in a similar way, using a single btrfs partition striping data over the two SSDs, but I don't feel comfortable synthesizing a method that I am sure will work with current software. What is the best way to partition and install Ubuntu over two SSDs using btrfs, in an effectively RAID 0 way?

• netflix on ubuntu 12.04

  - by tsi25

  So I have got Ubuntu 12.04 on a system 76 lemur ultra laptop. I installed netflix via terminal with the following chain of commands: sudo apt-get update sudo apt-add-repository ppa:ehoover/compholio sudo apt-get update sudo apt-get install netflix-desktop when it was finished installing, I clicked the icon and something came up asking if you want to install some dependent software, but wouldn't let me interact with the window - so I hit tab and worked my way through that. But my computer shutdown before I could fully install GECKO. Now I have the netflix icon, but when i click it or right click it nothing happens. I had tried uninstalling it with the following commands, sudo apt-add --purge remove netflix-desktop and then reinstalling it but there's no change. does anyone know what I can do to get netflix to run from here? or what I can do to start troubleshooting? I searched around on AskUbuntu but couldn't find any answers to this specific problem.

• Are python's cryptographic modules good enough?

  - by Aerovistae

  I mean, say you were writing professional grade software that would involve sensitive client information. (Take this in the context of me being an amateur programmer.) Would you use hlib and hmac? Are they good enough to secure data? Or would you write something fancier by hand? Edit: In context of those libraries containing more or less the best hashing algorithms in the world, I guess it's silly to ask if you'd "write something fancier." What I'm really asking here is whether it's enough on its own.

• Investigating a big C++ project from its source code [closed]

  - by user827992

  Possible Duplicate: What is the best method to start understanding BIG project source code? I have a project that I would like to dissect to learn something new from it. This project is about 200 megabytes. For me, it is just impossible to open every cpp and hpp file and read each and every one. I also don't know what is the best approach in this case. Many people on the internet are looking for an UML tool to generate some kind of graph. I think that UML works well when you are starting a project and you want to express the business logic of your classes and methods. In my opinion UML is totally useless when studying a project only from its source code. Also UML is an OO language, in a large sized C++ project I find a lot of stuff that is not an object and can express some other kind of paradigm. Can you name a tool or a class of software that can help with this?

• what exactly is system programming?

  - by kentjh

  I have never understood what system programming meant. The usual definition given is "...doing something close to the Os or extending Os features...". Does using Windows API directly rather than some libraries to say do file i/o make it system programming? Was writing Android OS system programming? If I write something that would expose linux kernel through a console like app on Android am I doing system programming? If I am writing software to control a washing machine am I writing system programming? I am a beginner in programming and this is confusing me to no end. Please explain contrasting it with "application programming".

• Minimum to install for a visual web browser in Ubuntu Server

  - by Svish

  I have set up a machine with Ubuntu Server. Some of the server software I want to run on it has web based user interfaces for setting it up et cetera. I know I could connect to it from a different machine which has a graphical user interface, but in this case I would rather do it on the box. So, from a fresh Ubuntu Server installation, what is the minimum I need to install to be able to launch a web browser I can use for this? For example chromium, firefox or arora.
