• Analysing Group & Individual Member Performance -RUP

  - by user23871

  I am writing a report which requires the analysis of performance of each individual team member. This is for a software development project developed using the Unified Process (UP). I was just wondering if there are any existing group & individual appraisal metrics used so I don't have to reinvent the wheel... EDIT This is by no means correct but something like: Individual Contribution (IC) = time spent (individual) / time spent (total) = Performance = ? (should use individual contribution (IC) combined with something to gain a measure of overall performance).... Maybe I am talking complete hash and I know generally its really difficult to analyse performance with numbers but any mathematicians out there that can lend a hand or know a somewhat more accurate method of analysing performance than arbitrary marking (e.g. 8 out 10)

  - by Paulo Truta

  Hello guys. I'm having a nasty problem with the Sound Menu on my Ubuntu 10.10 Installation. What happens is that the sound control icon is blocked, and i can't control the master volume. If i try to get to the Sound Preferences i get a little Pop-Up Window saying: "Waiting for Sound System to respond...". Don't know what to do... Apart of that, sound works great. Thanks a lot ;) PS: I made 2 screenshot uploads. Hope it helps.

• Automate #include refactoring in C++ [on hold]

  - by Mikhail

  I have a big project with hundreds of files. And as it often happens to C++ projects, #include directives are in messed up. I want to refactor them to increase clarity, decrease compilation time and simplify analysis. For each .h file I want to make sure that: It have #include directives only for types it is using But it have only forward declarations of types that are used as T* or T& For each .cpp file I want to make sure that: It have #include directives only for types it is using and not already included by another headers (no indirect includes when possible) I'm looking for a tool which will help me to automate this refactoring. For now I only know of tools that helps to remove redundant includes, they are many: PC-lint include-what-you-use cppclean ProFactor IncludeManager But I know of no tools to help me to move necessary includes in .h files or replace includes with forward declarations. Any ideas? Tools for Windows and Visual Studio are preferred. Update. Considered to be off-topic. Please, follow the link on Software Recommendations http://softwarerecs.stackexchange.com/q/4461/3331

• Version hash to solve Event Sourcing problems

  - by SystematicFrank

  The basic examples I have seen about Event Sourcing do not deal with out of order events, clock offsets in different systems and late events from system partitions. I am wondering if more polished Event Sourcing implementations rely on a version stamp of modified objects? For example, assuming that the system is rendering the entity Client with version id ABCD1234. If the user modifies the entity, the system will create an event with the modified fields AND the version id reference to which version it applies. Later the event responder would detect out of order events and merge them.

• Scrum for Team System v3 RTM available

  - by Enrique Lima

  If you are using the Scrum for Team System (aka Conchango Scrum Template), it has hit RTM and it is available for download.  First you will need to register and then you will ne able to access the goods. There is also a very well laid out Getting Started with v3 guide, put together by Crispin Parker. Note:  Very important to know and consider, is the fact there is no upgrade or migration strategy laid out from v2.2.  So you are left to your own devices on that one.  There are plenty of discussions going on as far as making it happen.  Don’t get me wrong v2.2 work items will be present and you will be able to use them, just don’t expect the v3 template to trigger when  adding new work items. For now, get TFS in place, install the template and start fresh.  The Workbench should be released soon too, and that makes it a great component to this solution.

• My Last "Catch-Up" Post for 2010 Content

  - by KKline

  I did a lot of writing in 2010. Unfortunately, I didn't do a good job of keeping all of that writing equally distributed throughout all of the channels where I'm active. So here are a few more posts from my blog, put on-line during the months of November and December 2010, that I didn't get posted here on SQLBlog.com: 1. It's Time to Upgrade! So many of my customers and many of you, dear readers, are still on SQL Server 2005. Join Kevin Kline , SQL Server MVP and SQL Server Technology Strategist...(read more)

• What is the Best way to learn c# programming and capability to do anything with C#?

  - by MSU

  I browsed all the answers given in Stackoverflow,i couldn't find my answer that's why i am writing this, so please don't mark this a duplicate. My case i want to get the capability of doing anything in C# from building applications to solving problems. I searched for and tried to read books. Then one of the experts said, reading books will not make any good for you, for learning you have to solve problems i.e. real world problems in C#, he gave me some sample problems, which i previously did in C++, i started doing, but the thing is that i know the internal logic of solving the problem or the algorithm to solve. But i don't know how to imepelement them using C# efficiently. so, the gap is, i can't think in C#, I know the message to passed but don't the exact way to pass it. I did a program to solve a problem, then find out there are much easier ways of doing it wherever i was doing it in tougher way. So, can you guys(C# experts) please enlighten me, what i need to get hold of the language and get the ability to code in C# proficiently?

• Complete RESTful API debugging/testing tool

  - by vartec

  I'm looking for the most complete tool, preferably portable GUI or browser plugin to test RESTful API. What I need is: GET/POST/DELETE/PUT support multiple file uploads as fields (multipart/form-data) file uploads as body Extra points for: possibility to save multiple configurations and use them to pre-fill parameters OAuth support nice JSON response formatting Currently I'm using 3 tools: Chrome REST Console extension — My favorite, very nicely done. Has OAuth. However the functionality missing for me is sending file as a body of the request; Cannot send multiple files; Firefox Poster add-on — Quite nice, but the functionality it's missing for file as POST fields parameters; Also cannot send multiple files; cURL — can do anything, but it's quite tedious to use it from command line.

• HD video editing system with Truecrypt

  - by Rob

  I'm looking to do hi-def video editing and transcoding on an unencrypted standard partition, with Truecrypt on the system partition for sensitive data. I'm aiming to keep certain data private but still have performance where needed. Goals: Maximum, unimpacted, performance possible for hi-def video editing, encryption of video not required Encrypt system partition, using Truecrypt, for web/email privacy, etc. in the event of loss In other words I want to selectively encrypt the hard drive - i.e. make the system partition encrypted but not impact the original maximum performance that would be available to me for hi-def/HD video editing. The thinking is to use an unencrypted partition for the video and set up video applications to point at that. Assuming that they would use that partition only for their workspace and not the encrypted system partition, then I should expect to not get any performance hit. Would I be correct? I guess it might depend on the application, if that app is hard-wired to use the system partition always for temporary storage during editing and transcoding, or if it has to be installed on the C: system partition always. So some real data on how various apps behave in the respect would be useful, e.g. Adobe, Cyberlink, Nero etc. etc. I have a Intel i7 Quad-core (8 threads) 1.6Ghz (up to 2.8Ghz turbo-boost) 4Gb, 7200rpm SATA, nvidia HP laptop. I've read the excellent posting about the general performance impact of truecrypt but the benchmarks weren't specific enough for my needs where I'm dealing with HD-video and using a non-encrypted partition to maintain max performance.

• Down Time

  - by andyleonard

  Introduction Every now and then, everyone needs a break. How do we respond when community leaders need a break? How should we respond? It's Normal People are cyclic animals - humans are diurnal by nature. We eat at regular intervals and are most comfortable when things go according to schedule. This is the lizard brain in action. So it's perfectly normal for community volunteers and leaders to engage in cycles of activity and inactivity in the community. It is, after all, another cycle. We rely on...(read more)

• Seeking a free Lint for C which programmers will *want* to use

  - by Mawg

  When I try to persuade others to Lint their code I always get excuses - too difficult to set up, too difficult to understand, false positives, etc (most of which translates to too lazy, too stupid or too afraid of new things). Is there any way that I can make Linting easier? We code in C using Netbeans. Can I incorporate Splint into Netbeans? I did find a Splint GUI which was quite good, but there was no way to lint a directory tree. Any ideas? Thanks in advance

• Mail Scanning System

  - by Mr D

  In the same way gmail can generate ads based on email content, I am looking for a way to develop a system which can: Allow users to connect their email address to our site It then would continously monitor all incomming emails From the incomming emails there would be a critera(e.g. a certain address or subject) if any of the emails matched the critea it would would be saved to a database Then once a new email had been found the users would receive an email notification will tells them to log back into the site to see it. My questions are: Would this be possible? What would be a good language to use(generally I like php, python and java) Are there any frameworks which would help do this? How would I connect the users email account to allow access to their emails(do I need a mail server?) Any advice? Thank you! If you need more information please let me know.

• file copy error from system to cifs mount

  - by dwpriest

  When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy locally and between the mount and system via SSH just fine. Any ideas? Thank you

• Efficient existing rating system for multiplayer?

  - by Nikolay Kuznetsov

  I would like to add a rating for online version of a board game. In this game there are many game rooms each normally having 3-4 people. So I expect that player's rating adjustments (RA) should depends on Rating of opponents in the game room Number of players in game room and final place of a player Person gets rating increase if he plays more games and more frequently If a person leaves a game room (disconnect) before the game ends he should get punished with a high rating decrease I have found two related questions in here Developing an ELO like point system for a multiplayer gaming site Simplest most effective way to rank and measure player skill in a multi-player environment? Please, let me know what would be the most appropriate existing rating model to refer.

• How are minimum system requirements determined?

  - by Michael McGowan

  We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

• Scalable distributed file system for blobs like images and other documents

  - by Pinnacle

  Cassandra & HBase both do not efficiently support storage of blobs like images. Storing directly on HDFS stresses the Namenode because of huge number of files. Facebook uses Haystack for images and attachments storage, but this is not open source. So is Lustre a good choice for distributed blob storage? I have read that Amazon S3 is used by many, but this would cost money and personally, I would not like to rely on third party system. What are other suggestions?

• Software/Hardware Development?

  - by SwarthyMantooth

  Sincere apologies if this is the wrong place to ask this. I am a computer engineering student and I'm currently on my first co-op of the required 5 I have to take, and I've noticed that all I'm really given is software engineering jobs. I love developing software, but I don't want to lose out on the hardware aspect of computers, as having a hybrid knowledge of the two is why I chose this major in the first place. So I guess my question is: Are there any software engineering jobs that still allow you to handle and interface with hardware on a very low level? Or am I to be forced to choose which focus I love more?

• How USB drives goes after system hard drives

  - by raihanchy

  I am using Ubuntu 12.04 LTS. My hard drives usually comes as: sda, with 'sudo blkid' and if I plug-in any USB drive, they comes as: sdb, sdc etc; after sda. That's fine!!! But problem arises after I restart my laptop with connecting those USB drives. They alter and comes first and hard drive goes to the end, like: 'sudo blkid' shows, sda, sdb for USB drives and sdc for hard drives. It's making problem to mount with /etc/fstab. I couldn't find any solutions for this. I would like to have any USB drives after my system hard drives, as in Windows. Please, help me at this point. Thanking you. Raihan

• Finding Telecommuting Opportunities as a Recent College Graduate

  - by stanigator

  Reading the answers to hiring practices of remote vs. local employees and freelance programming sites, I would like to add this question to the mix. I am a recent college graduate from an electrical engineering background with 2 years worth of work terms in programming (C, C++, VBA, Matlab, etc.) while I was still in school. While I am interested in learning other software tools (such as Python, Ruby on Rails, Javascript, etc.), I want to use the tools I have now in a telecommuting role while I grow my toolset. Despite having 2 years of work experience (and I've lost track of when I have started programming), my status as a recent college graduate may be an obstacle of my credibility to compete for telecommuting (or in fact any) programming opportunities. I don't know how I can go about finding telecommute programming opportunities for someone with my situation. Overall, many of previous places I've worked at liked my work. What are your suggestions? Thanks in advance!

  I am looking at using a version control system to ensure that I can go back in time to a particular version for all documents in ~, if I have to. What is the best suited tool for this given that: I am without much experience in version control systems Several files will be plain text files but there will be some Libre-Office files also The tool should: Be easy to set-up, run and maintain Have easy to understand configuration options (what directories to track, for how long, how frequently the changes should be captured, etc.) Ideally have a GUI front also Be able to recover deleted files What is the best/ most widely used tool that will be suitable for me?

• Get access to files on old HD installation and remove system files

  - by Blake

  I have been fooling with ubuntu for only a year or so. Added SSD installed ubuntu(12.04 64bit) connected old drive with ubuntu on it. everything seems to work well, except for access to some files. I would like to do two things: 1) move the swap file from the SSD to the partition on the HD. 2) remove ubuntu system files and gain full access to my other files. I can still remove the SSD and run ubuntu from the HD, so if I am approaching this incorrectly please advise. Thanks in advance Blake
