  • Developer momentum on open source projects

    - by sashang
    Hi I've been struggling to develop momentum contributing to open source projects. I have in the past tried with gcc and contributed a fix to libstdc++ but it was a once off and even though I spent months in my spare time on the dev mailing list and reading through things I just never seemed to develop any momentum with the code. Eventually I unsubscribed and got my free time back and uncluttered my mailbox. Like a lot of people I have some little open source defunct projects lying around on the net, but they're not large and I'm the only contributor. At the moment I'm more interested in contributing to a large open source project and want to know how people got started because I find it difficult while working full time to develop any momentum with the code base. Other more regular contributors, who are on the project full-time, are able to make changes at will and as result enter that positive feedback cycle where they understand the code and also know where it's heading. It makes the barrier to entry higher for those that come along later. My questions are to people who actively contribute to large opensource projects, like the Linux kernel, or gcc or clang/llvm or anything else with say a developer head count of more than 10. How did you get started? Was there a large chunk of time in your life that you just could dedicate to working on the project? I know in Linus's case he had a chunk of time (6 months) to get it started. What barriers to entry did you encounter? Can you describe the initial stages of the time spent with the project, from when you had little understanding of the code to when you understood enough to commit regularly. Thanks

  • Social Media APIs and Their C# Counterparts

    Whether it's talking about current events or sharing photos of a family vacation, the world is now addicted to social networks. Businesses recognize this, and these days every business wants social media addressed in their applications. Facebook, Twitter, and other sites provide powerful APIs you can use to harness the power of social networking in your own applications. However, most of these APIs tend to return data formatted in any number of syndication formats that can be quite painful to work with. Luckily, there are many free .NET based libraries that make interacting with these APIs a breeze. Over the next several weeks, I'll be posting some information and examples specific to some of these libraries. Here are a few of them now for your consumption... TweetSharp Twitter exposes its API in the form of three different APIs, two REST APIs and one Streaming API. These APIs can be queried by making HTTP GET/POST requests to a specific URL with some required parameters. Unfortunately, ...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.

  • Partitioning Software for Windows 7

    - by nunos
    I used to use Patition Magic Pro from Norton to do disk partitioning. Now that I have Windows 7, I have been warned, by the OS itself and later confirmed on the internet, that Partition Magic Pro has compatibility issues with Windows 7. So, I am asking you which software partitioning software do you recommend. It would be great if it was freeware but I know it is hard to find a good parititioning app that's free, so, if you know a good one that's paid, there's no problem and please mention it in your reply. Thanks in advance. P.S. I am aware of "create and format disk partitions feature" of Windows 7, but that's not enough for me. I am using Windows 7 Professional 64 bits.

  • I need a way to read web feeds that meets the following requirements

    - by Daddy Warbox
    Requirements: Can be set as always on top of other windows. Can be moved and resized freely. Adjustable refresh times and/or a reload button. Text-only is fine. I will need to open hyper links, though. Simple and cheap free. Offline caching. If you know of a program that does all of this, can you tell me what settings I need to adjust to get it to do this? Thanks in advance.

  • What is a easiest way to implement Mail Server in ubuntu and hook in webmail through XAMPP?

    - by Parris
    Hi Everyone, I currently have xampp running on my ubuntu server. I tried a variety of things including installing, postfix+dovecot+roundcube+postfixadmin (postfix+dovecot work I think, postfix admin also works, roundcube works and connects to dovecot but i cant create user accounts, or figure out how that works), citadel (it installed, but I have no idea how to make it work with xampp for webmail) and i tried messing with exim and vexim a bit also. In short I feel like this should be a lot easier, and I can't figure it out haha. XAMPP works fine. I got my server running with everything. I was thinking about mercury mail, but I need a webmail solution also. I was thinking about google apps, but 50 bucks a year per user is a steep change from free. Thanks for the help!

  • Oracle R Distribution 2-13.2 Update Available

    - by Sherry LaMonica
    Oracle has released an update to the Oracle R Distribution, an Oracle-supported distribution of open source R. Oracle R Distribution 2-13.2 now contains the ability to dynamically link the following libraries on both Windows and Linux: The Intel Math Kernel Library (MKL) on Intel chips The AMD Core Math Library (ACML) on AMD chips To take advantage of the performance enhancements provided by Intel MKL or AMD ACML in Oracle R Distribution, simply add the MKL or ACML shared library directory to the LD_LIBRARY_PATH system environment variable. This automatically enables MKL or ACML to make use of all available processors, vastly speeding up linear algebra computations and eliminating the need to recompile R.  Even on a single core, the optimized algorithms in the Intel MKL libraries are faster than using R's standard BLAS library. Open-source R is linked to NetLib's BLAS libraries, but they are not multi-threaded and only use one core. While R's internal BLAS are efficient for most computations, it's possible to recompile R to link to a different, multi-threaded BLAS library to improve performance on eligible calculations. Compiling and linking to R yourself can be involved, but for many, the significantly improved calculation speed justifies the effort. Oracle R Distribution notably simplifies the process of using external math libraries by enabling R to auto-load MKL or ACML. For R commands that don't link to BLAS code, taking advantage of database parallelism using embedded R execution in Oracle R Enterprise is the route to improved performance. For more information about rebuilding R with different BLAS libraries, see the linear algebra section in the R Installation and Administration manual. As always, the Oracle R Distribution is available as a free download to anyone. Questions and comments are welcome on the Oracle R Forum.

  • CMS for coding blog

    - by OrgnlDave
    I've got a server with a LAMP stack and such. I'd like to host a blog-type site (or if there's a free place good for this, that would be cool!) that covers a variety of tutorials, interesting content, etc. There are tons of CMS's out there but if you search for tips on ones that do programming type things well, you get tons of hits about web development. I'd like to know if anyone here has recommendations from actually using a CMS for this type of thing or, short of that, can recommend one - not based on generalities like "Joomla! is great!" I'm looking for the least setup time possible. I'm proficient with CSS and I can design a color scheme, so that's not a big problem. As you can expect, attaching files, pictures, and syntax highlighting are musts (C/C++ ish is good). Ability to group posts, perhaps use tags, etc. would be cool too, but not necessary. As I'm writing this, it almost sounds like it'd be easier to custom-code a small PHP site myself.

  • How to convert an image to a .dwg file

    - by erikric
    My girlfriend is making an art project where she is having an image printed and cut out on a metal plate. The firm responsible for doing this is demanding a .dwg file (and something called polyline; some sort of setting maybe?). Neither of us have heard about this file format, and I find the information about it quite confusing. Most pages seem to link to some schetchy "FooToBarConverter" software, that I frankly don't trust. Could someone please enlighten us on what we need to do, or point to some safe and preferably free software that could do this? (An explanation of the dwg format and the polyline thing would also be much appreciated)

  • Business Intelligence (BI) Defined

    CIO.com defines Business Intelligence (BI) as a generic reference to a collection of applications that are used to analyze raw organizational data. Typical BI activities include data mining, online analytical processing, querying and reporting. They further explain that the primary reason why a company would utilize BI is to make their more data accessible. The more accessible data is to the users the faster they can identify ways to reduce business cost, discover new business opportunities, and react quickly to adjust prices based on current supply and demand. One area in which a hospital system could use BI derived from a data warehouse can be seen in the Emergency Room (ER) in regards to the number of doctors and nurse they have working during a full moon for each ER location. In order determine this BI needs to determine a trend in the number of patients seen on a full moon, further more they also need to determine the optimal number of staff members working during a full moon be determining the number of employees to patients ration needed to meet standard patient times and also be the most cost effective for the hospital.  This will allow the hospital system to estimate the number of potential patients they will have on the next full moon and adjust their staff schedules accordingly to ensure that patient care is not affected in any way do the influx or lack of influx of patients during this time while also ensuring that they are only working the minimum number of employees to ensure that they still making a profit. Another area where a hospital system could use BI data regards their orders paced to drug and medical supply companies. BI could define trends in prescriptions given to patients, this information could be used for ordering new supplies and forecasting the amount of medicine each hospital needs to keep on site at a given time. For example, a hospital might want to stock up on materials need to set bones in a cast prior to the summer because their BI indicates that a majority of broken bones occur during the summer due to children being out of school and they have more free time.

  • What tools should I use to edit H.264 MP4 GoPro videos?

    - by WW.
    I have recorded videos using a GoPro, which produces MP4 files containing H.264 encoded videos. I would like to do some simple editing tasks on these videos without losing quality:- Cut various scenes together Change soundtrack I'm using Windows XP Pro so I have Windows Movie Maker which seems like it should be sufficient but can not read the MP4 files that I have. Can I install a codec to allow WMM to read the MP4 files? Can I convert from MP4 to something that WMM reads? Is there a different video editing program that I should use? Free software would be preferable, but I'm willing to pay if it's a superior solution.

  • Solaris at LISA 2011

    - by dminer
    As is our custom, the Solaris team will be out in force at the USENIX LISA conference; this year it's in Boston so it's sort of a home game for me for a change.  The big event we'll have is Tuesday, December 6, the Oracle Solaris 11 Summit Day.  We'll be covering deployment, ZFS, Networking, Virtualization, Security, Clustering, and how Oracle apps run best on Solaris 11.  We've done this the past couple of years and it's always a very full day.On Wednesday, December 7, we've got a couple of BOF sessions scheduled back-to-back.  At 7:30 we'll have the ever-popular engineering panel, with all of us who are speaking at Tuesday's summit day there for a free-flowing discussion of all things Solaris.  Following that, Bart & I are hosting a second BOF at 9:30 to talk more about deployment for clouds and traditional data centers.Also, on Wednesday and Thursday we'll have a booth at the exhibition where there'll be demos and just a general chance to talk with various Solaris staff from engineering and product management.The conference program looks great and I look forward to seeing you there!

  • How to get a maximum file size of VZFS parition?

    - by Nulldevice
    I have a VPS hosting with a VZFS file system. How can I determine maximum file size of VZFS partition? UPD: Free space (or total space) is not what i need. Sometimes file cannot occupy a hole partition volume - fat16 with 2Gb limit is a good example. I need to use a large database file (say, 64Gb) and so I need to know if a file system of VPS hosting will cope with it. It is easy to calculate for an ext3 filesystem using tune2fs, but VPS uses VSFS by Virtuozzo, and it is documented bad. Is it any generic way to calculate maximum file size for some filesystem in linux?

  • Lubuntu 12.04 on Acer laptop boots to blank blue screen

    - by WGCman
    My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

  • Looking for an alternative to PuTTY on Windows

    - by mririgo
    PuTTY is good at what it does, but I'm somewhat envious of Mac Terminal and even Ubuntu's Terminal. I'm looking for good alternatives to PuTTY that would include some of the aesthetics found in Mac and Ubuntu's Terminal applications. Tabs! The ability to drop the window's opacity The ability to open right to the command prompt and ssh in (no intial config window every time) Etc. Feel free to share any Windows terminal applications you would recommend. Or maybe it's possible to get PuTTY to do some of these things. Whatever, I'm cool with that.

  • Increasing Screen Resolution to more than limit and scaling to origional

    - by Akshat Mittal
    I have a laptop, with Screen Resolution - 1366x768 (most common) - I want to increase it further to 1600x900 (or higher), in the same ratio. I want to scale the higher resolution on my current screen to fit it. I found xrandr with command xrandr --output LVDS1 --scale 1.4x1.4, this worked but again resulted to another problem, it does the scaling thing but the cursor is still blocked into the native screen resolution and I am not able to move it further, I found that the bug is already filed here. Also this command was only for Linux, I wanted to do this thing with both Linux and Windows (including Windows 8). I want a similar software that is bug free (at least not a major bug like this) and that supports Windows as well (or two separate software for Windows and Linux). Any help is appreciated and Thanks in advance.

  • Finding Missing UDP Frames Using Wireshark + Custom Dissector (for CQS)

    - by John Dibling
    How do you use Wireshark to identify missing UDP frames? I have written a custom dissector for the CQS feed (reference page). One of our servers gaps when receiving this feed. According to Wireshark, some UDP frames are never received. I know that the frames were sent because all of our other servers are gap-free. A CQS frame consists of multiple messages, each having its own sequence number. My custom dissector provides the following data to Wireshark: cqs.frame_gaps - the number of gaps within a UDP frame (always zero) cqs.frame_first_seq - the first sequence number in a UDP frame cqs.frame_expected_seq - the first sequence number expected in the next UDP frame cqs.frame_msg_count - the number of messages in this UDP frame And I am displaying each of these values in custom columns, as shown in this screenshot: A typical CQS log will consist of millions of rows, so I can't just eyeball it. Is there any way I can get Wireshark to tell me which frames are missing?

  • How do you KISS?

    - by Conor
    The KISS principle is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc Why KISS practices do you apply? How have they been of benefit? I'm especially interested in non-obvious practices.

  • Software Licencing [closed]

    - by Craig
    A colleague of mine wanted a means to do something, so it was suggested that I write some software to do this. The software has turned into more than the original specification and is now something rather complex, however it is not fully functional still. My colleague has not paid me anything so far and I am unwilling to continue writing the software until some faith has been reciprocated in my direction, as I have put a lot of effort into writing the software. I am also unwilling to finish the software as I do not want to give away a huge chunk of my time and effort away as free, neither do I want to be under compensated for my efforts. Some concerns I have. If I finish the software, what if the client doesn't pay me anything or pays too little, or what if I write the software to a usable level, but not complete and the client pays me a too little. I have lost my motivation to finish the software, as more and more specifications have been added to the software and I have developed a substantially complex piece of software and been effectively paid nothing. To finish the software, I need motivation, money would do this, however the client doesn't want to pay for something that isn't complete, yet keeps adding more requirements. I seem to be in a catch 22 with this, as I have developed some software on faith and have had no faith reciprocated in my direction. I'm really not sure how to get some payment from the client or on how to develop a licencing model so that I get some money from the client and development resumes.

  • Windows Embedded Compact 7

    - by Valter Minute
    This will be the official name of the new release of Windows CE. Windows Embedded Compact 7 is available as a public CTP and it already supports a wide range of CPUs and both the device emulator and VirtualPC emulated environments. So I’ll have to learn a new (and longer) name for my favorite OS… but I (and all my two readers!) will be able to test it as soon as the download from connect web site completes (I'm sorry for my readers, but you'll have to download it by yourselves). Here’s a link for the download (it's free but you’ll have to register on connect with a valid LiveId): https://connect.microsoft.com/windowsembeddedce Remember that this is still a beta (or “Community Technology Preview” if you speak marketing language) and so it’s better to not install it on your main development PC (or, at least, backup everything before installation) and that the features and performances you’ll get from this beta may not be the same ones of the final release of the OS. You can discover the new features of Windows Embedded Compact on the new “official” webpage on microsoft website: http://www.microsoft.com/windowsembedded/en-us/products/windowsce/compact7.mspx or on Olivier’s blog: http://blogs.msdn.com/b/obloch/archive/2010/06/01/windows-embedded-compact-7-announced-and-public-ctp-available.aspx I hope to be able to post some interesting content about Windows Embedded Compact 7 soon (and maybe be able to shorten it’s name in CE7 in my blog posts, when I'll ensure that both my readers are not worketing for Microsoft's marketing department …).

  • Input/Output console window in XNA

    - by Will Bagley
    I am currently making a simple game in XNA but am at a point where testing various aspect gets a bit tricky, especially when you have to wait till you have 1000 score to see if your animation is playing correctly etc. Of course i could just edit the starting variable in the code before I launched but I have recently been interested in trying to implement a console style window which can print out values and take input to alter public variables during run-time. I am aware that VS has the immediate window which achieves a similar thing but i would prefer mine is an actual part of the game with the intention that the user may have limited access to it in the future. Some of the key things i have yet to find an answer to after looking around for a while are: how i would support free text entry how i would access variables during runtime how i would edit these variable I have also read about using a property grid from windows form aps (and partially reflection) which looked like it could simplify a lot of things but i am not sure how I would get that running inside my XNA game window or how i would get it to not look out of place (as the visual aspect of is seems to be aimed just for development time viewing). All in all I'm quite open to any suggestions on how to approach this task as currently I'm not sure where to start. Thanks in advance.
