  • Are there Negative Impact of opensource on commercial environment?

    - by Lostsoul
    I know this is not a good fit for Stack Overflow but wasn't sure if it was good for this site also so let me know if its not and I'll delete it. I love programming for fun but my role in my company is not technical. I have always loved the hacker culture and have been trying to drive that openness within my company from day one. My company has a very broad range of products and there are a few that are not strategic to us so I wanted to open source them (so we can focus on what makes us unique and open source the products that every firm has). Our industry does not open source(we would be the first firm to try this) and the feedback I'm getting from my management team is either 1) we'll destroy the industry or 2) all competitive commercial firms will unite against us and we'll be wiped out either way. I disagreed on both points because I think transparency will only grow our industry and our firm (think of McDonalds/KFC sharing their recipe openly, people may copy you, competitors may target you, but customers also may feel more comfortable buying your product. The value add, I believe, is in the delivery and experience not in hoarding the recipe). It's a big battle in my firm right now between the IT people who have seen the positive effects of sharing and the business people who think we'll be giving up everything (they prefer we sell parts we want to opensource, but in their defense this is standard when divesting something). Our industry is very secretive and I don't want to put anyone(even my competitors employees) out of a job yet I don't want to protect inefficient people by not being open with everyone. Yet I've seen so many amazing technologies created in interesting ways just by giving people freedom to take apart code and put it back together. I'm interested in hearing people's thoughts(doesn't have to be to my specific situation, I'm looking for the general lessons). Its a very stressful decision(but one I feel I must make) because if we go the open source route then there will be no going back. So what are your thoughts? Does open sourcing apply generally or is it only really applicable to software? Is it overall good for people in the industry and outside? I'm actually more interested in the negativeness effects(although positive are welcomed as well) Update: Long story short, although code is involved this is not so much about code as it is more about the idea of open sourcing. We are a mid sized quant hedge fund. We have some unique strategies but also have the standard long/short, arbitrage, global macro, etc.. funds. We are keeping the unique funds we have but the other stuff that everyone else has we are considering open sourcing (We have put in years of work & millions of dollars into. Our funds is pretty popular and our performance is either in first or second quartile so I suspect there will be interest but I don't know to what extent). The goal is not to get a community to work for us or anything, the goal is to let anyone who wants to tinker with it do so and create anything they want (it will not be part of our product line although I may unofficially allocate some our of staff's time to assist any community that grows). Although the code base is quite large, the value in this is the industry knowledge and approaches we have acquired (there are many books on artificial intelligence and quant trading but they are often years behind what's really going on as most firms forbid their staff from discussing what they are doing). We are also considering after we move our clients out to let the software still run and output the resulting portfolios for free as well so people can at least see the results(as long as we have avail. infrastructure). I think our main choices are, we can continue to fight for market share in a products that are becoming commoditized, we can shut the funds/products down(and keep the code but no one outside of our firm will ever learn from it) or we can open source it and let people do what they want. By open sourcing it, my idea is that the talent pool in the industry will grow because right now most of our hires have the same background (CFA, MBA, similar school, same experience,etc.. because we can't spend time training people so the industry 'standardizes' most people and thus the firms themselves start to look/act similar) but this may allow us to identify talent that has never been in the industry before (if we put a GPU license then as people learn from what we did, we can learn from what they do as well and maybe apply it to other areas of our firm). I see a lot of benefits but not many negatives while my peers at the company see the opposite.

  • Is JScript dying? If so, where should I go? [closed]

    - by David Is Not Here
    I recently poked around Google for a little bit, looking for information about coding JScript. It's very sparse, which surprised me -- it took a link to a link to find Microsoft's own reference, which appears to omit most if not all references to console-based scripting that extends past Javascript. I'm working with the console here, not a webpage, so input and output seems very different than what Microsoft explains. If JScript is dying (and it appears to be so), where do I go from here? VBScript? My options are limited because the computers I'm using this on are carefully patrolled for new software. JScript's similarity to JavaScript was the biggest reason I had chosen it for porting over some of my prior work. I'm specifically looking for, at best, a console scripting language that doesn't need any extra software on Windows XP or higher, that at least supports standard input, output, pause, and file manipulation, little else.

  • How to get BURG on 12.10 (Quantal Quetzal)

    - by Warpspace
    I've been using BURG for years to get rid of the eye sore that is the standard GRUB interface. When I upgraded to Quantal, the repository does not contain the updated information. I.e. after I add sudo add-apt-repository ppa:n-muench/burg sudo apt-get update I get the annoying response W: Failed to fetch http://ppa.launchpad.net/n-muench/burg/ubuntu/dists/quantal/main/binary-amd64/Packages 404 Not Found It's been like this for a month, contrary to various websites which say it works. Is BURG being maintained? Have they created a better alternative (such as integration with GRUB, like it should have been in the first place). How do I get a decent-looking bootloader?

  • Is it possible to use two different shells for different terminal windows?

    - by NES
    Is it possible to use another shell for scripts than for standard terminal use? The problem is, i use fish as shell at the moment and i find i very convenient. But i would like to learn a bit of shell programming in Ubuntu. Since there are differences between those two it would be nice, to work with fish and bash at the same time, perhaps in different terminal windows? i know i can write a shell script and have to put the interpreter in the beginning. But for testing developing at commandline i would find it useful to fast switch between shells or use two different terminal windows with different shells in one session at the same time?

  • Which iso image do I need to install Ubuntu 12.04 on a Macbook Pro so that it boots using UEFI?

    - by gentmatt
    Unlike with earlier releases, the website is unclear on giving a straight recommendation for installing ubuntu on a mac: http://cdimage.ubuntu.com/releases/12.04/release/ I've read several times, that I should use an alternative image. But this is only offered as 64-bit. However, I'm also told to rather use 32-bit images for better software compability. http://cdimage.ubuntu.com/releases/12.04/release/ubuntu-12.04-alternate-amd64+mac.iso Even though I should only use alternative images, there is offered a standard desktop image which is "adjusted to work properly on Mac systems". http://cdimage.ubuntu.com/releases/12.04/release/ubuntu-12.04-desktop-amd64+mac.iso Question Which image should I take? Do both of these images offer UEFI boot? I've tried both of them already, but both have setup an install with BIOS emulation. This is quite annoying because of the short battery life and high temperatures which are harmful to battery longevity.

  • C# and SQL data layer code generator

    I've created a simple yet efficient tool to help generate stored procedures and a C# data access layer from a table.  Instead of using an ORM, this uses standard ADO .NET (SqlConnection, SqlDataReader, etc).  Check it out at www.asteio.com.  It's saved me a ton of time and I'm hoping it does the same for you....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Is it OK to mix C and C++ in an interview?

    - by John Pell
    If I am asked in an interview to write down some code, should I completely stick with C++ or is it acceptable to "mix" the two to write easy code as it comes to my mind? I'll explain it: if I'm asked to create a "stack" data type, a C++ class is perfectly suited, while if I need to parse some strings a strtok/sscanf is far easier than STL. On the other hand, if I need a generic container STL and templates are the way to go. Everything can be done in C or in C++, but in an interview I can't code everything or remember every standard/STL function. What is an acceptable tradeoff?

  • After Upgrade from 13.04 to 13.10 missing user in login screen

    - by Mark
    I have upgraded to 13.10 from 13.04 now after booting (even after updates and rebooting) my user id is not listed. It has a uid higher than the minimum in lightdm.conf. I have the user light display manager , guest , and remote login options in the login screen but not my ususal user id that I have been using from ubuntu 9 something. It is a normal user and an administrator so that I could authorize drivers, updates, etc... I do not have any custom display manager setup. It has been standard unity since unity was available. I can login to my account by logging in as guest opening a termial and using su - user Any insight would be appreciated. Thanks

  • Visual Studio 2010 HTML5

    - by Renso
    Goal: Enabling HTML5 validation and  IntelliSense for Visual Studio 2010. By default it is set to XHTML 1.1. HTML5 support only came included with SP1 of Visual Studio 2010. However since HTML5 is not an official standard as yet and some of the 30 new elements are not suported in all browsers, so only a subset of the entire HTML5 specification is supported; support for both intellisense and validation for HTML5 with SP1. How to: After installing SP1 you have to tell Visual Studio to start using the HTML5 schema. Go to Tools -> Options, and then select Text Editor -> HTML -> Validation. Select HTML5 or XHTML5 as the target schema. So start building or converting older Visual Studio projects to HTML5 and CSS3 web applications.

  • Is "convention over configuration" not violating basic programming principles?

    - by Geerten
    I was looking at the WPF MVVM framework Caliburn.Micro and read that a lot of standard things are based on naming conventions. For example, automatic binding of properties in the View to properties in the ViewModel. Although this seems to be convenient (removes some boilerplate code), my first instinct reaction is that it isn't completely obvious to a new programmer that will read this code. In other words, the functionality of the application is not completely explained by its own code, but also by the documentation of the framework. EDIT: So this approach is called convention over configuration. Since I could not find any questions concerning this, I altered my question: My question is: Is convention over configuration a correct way of simplifying things, or is it violating some programming principles (and if so, which ones)?

  • Monitor aspect ratio; Does the difference matter?

    - by Craige
    So, I'm looking ordering myself a new development desktop soon and setting up a PROPER office environment by the end of this year. To boost productivity, I'm going to purchase three new monitors. I find that two just isn't enough when I'm debugging or doing something intensive. That said, I had something pointed out to me the other day that I never really noticed nor cared about before - is the difference between a 16:10 and a 16:9 monitor noticeable when programming? Do you really miss those few extra lines, or is it something that you don't notice at all. I notice HP only seems to sell 16:9 monitors (as far as I have found). Is this becoming something of a new standard with the recent growth and cleaver marketing of of "HD 16:9"? To summarize: Has anybody made the switch from 16:10 to 16:9 (or vise-versa) and actually noticed the difference while programming?

  • Quality Assurance=inspections, reviews..?

    - by user970696
    Studying this subject extensively, the most books state the following: Quality Assurance: prevention activity. Act of inspection, reviewing.. Quality Control: testing While there are some exceptions that mention that QA deals with just processes (planning, strategy, standard application etc.) which is IMHO much closer to real QA, yet I cannot find any good reference in Google Books. I believe that inspections, reviews, testing is all quality control as it is about checking products, no matter if it is the final one or work products. The problem is that so many authors do not agree. I would be grateful for detailed explanation, ideally with a reference.

  • Need instructions on how to create wpa_supplicant.conf and add fast_reauth=0 to it

    - by nutty about natty
    Like many other natty users on a university/academic network, I'm experiencing annoying frequent disconnects/hangs/delays. See, for instance here. I would like to learn how to add fast_reauth=0 to the wpa_supplicant.conf file. This file, it seems, does not exit by default, and needs to be manually created first: README You will need to make a configuration file, e.g. /etc/wpa_supplicant.conf, with network configuration for the networks you are going to use. Further, I installed wpa_gui which probably needs to be launched with parameters, else it's pretty blank... What I'm hoping for is this: That creating a wpa_supplicant.conf file with fast_reauth=0 in it, saving it to the relevant path, will work and make my uni wireless (more or even completely) stable. I read mixed reviews about wicd (as an alternative to the network manager). Also note that on my basic wlan at home (with bog-standard wpa encryption) the connection is stable. Thanks!

  • SQL Why is prefixing column names considered bad practice?

    - by P.Brian.Mackey
    According to a popular SO post is it considered a bad practice to prefix table names. At my company every column is prefixed by a table name. This is difficult for me to read. I'm not sure the reason, but this naming is actually the company standard. I can't stand the naming convention, but I have no documentation to back up my reasoning. All I know is that reading AdventureWorks is much simpler. In this our company DB you will see a table, Person and it might have column name: Person_First_Name or maybe even Person_Person_First_Name (don't ask me why you see person 2x) Why is it considered a bad practice to pre-fix column names? Are underscores considered evil in SQL as well? Note: I own Pro SQL Server 2008 - Relation Database design and implementation. References to that book are welcome.

  • Could it be more efficient for systems in general to do away with Stacks and just use Heap for memory management?

    - by Dark Templar
    It seems to me that everything that can be done with a stack can be done with the heap, but not everything that can be done with the heap can be done with the stack. Is that correct? Then for simplicity's sake, and even if we do lose a little amount of performance with certain workloads, couldn't it be better to just go with one standard (ie, the heap)? Think of the trade-off between modularity and performance. I know that isn't the best way to describe this scenario, but in general it seems that simplicity of understanding and design could be a better option even if there is a potential for better performance.

  • reinstalling totem 3.0.1 from source

    - by user1537727
    I have totem 3.0.1 installed on my system, but I wish to install from source the same and when I do so i am presented with the following dependency errors. How can this be possible? configure: error: Package requirements ( glib-2.0 >= 2.27.92 gio-2.0 >= 2.27.92 gtk+-3.0 >= 2.99.3 gdk-x11-3.0 >= 2.99.3 gmodule-2.0 totem-plparser >= 2.32.4 gstreamer-tag-0.10 >= 0.10.26 cairo) were not met: No package 'totem-plparser' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables DEPENDENCY_CFLAGS and DEPENDENCY_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details.

  • In Rhythmbox, is there a way to sort by artist and search by title?

    - by duxk.gh
    In Rhythmbox I sort my music by artist. When I quickly want to look for a song I'd like to type in the title of the song. Not in the standard search box up top, but by starting to type when I've clicked anywhere in the list of songs. A small search box appears in the right bottom corner just like it does in Nautilus. The thing is, when I sort by artist that search looks up the artist as well. When I sort by title, it searches by title. I'd like to sort by artist, but search by title. Is there a way to do that?

  • Get and install Nvidia GeForce 8400 GS driver

    Recently, I changed my OS kernel from 10.04 to 11.10 (bugs), but after doing it, the video driver for the 8400 GS disappeared (was there in 10.04). I worked out the same procedure I did to install it in 10.04, mainly, sudo apt-get --purge remove nvidia-current sudo apt-get --purge autoremove sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get -y install nvidia-current but it didn't work even though the commands seemed to install the driver without problems.

  • Technical Article: Experimenting with Java Timers

    - by Tori Wieldt
    OTN's new tech article is "Experimenting with Java Timers" by T. Lamine Ba. This article studies time—how Java handles timers and the scheduling of tasks. Java timers are utilities that let you execute threads or tasks at a predetermined future time, and these tasks can be repeated according to a set frequency. The article starts with a simple "Hello World" program in a web application that's composed of JavaServer Pages (JSP) and uses the model-control-view (MVC) design pattern. The IDE used in this article is NetBeans IDE 7.1, but you can use any IDE that supports Java. "Experimenting with Java Timers" demonstrates how to get started scheduling jobs with Java. To learn about Swing timers, check out the Java tutorial "How to Use Swing Timers" and additional information in the Java Platform, Standard Edition 7 API Specification for Class Timer.
