• Best way to integrate StyleCop with TFS CI

  - by Slavo

  I've been doing research on how to enable source analysis for the project I'm working on and plan to use StyleCop. The setup I have is a TFS Server for source control, using TFS Continuous Integration. I want to enable source analysis for CI builds and daily builds run on the build machine, and not only for those run on developers' machines. Here's an article from the documentation of StyleCop that I read on the subject: http://blog.newagesolution.net/2008/07/how-to-use-stylecop-and-msbuild-and.html. It basically modifies the csproj file for the purpose. I've also read other opinions about how StyleCop should be integrated with build automation, which advise doing the same thing using build tasks: http://blog.newagesolution.net/2008/07/how-to-use-stylecop-and-msbuild-and.html http://freetodev.spaces.live.com/blog/cns!EC3C8F2028D842D5!400.entry. What are you opinions? Have you had similar projects and done something like this?

• NFS issue: clients can mount shares as NFSv3 but not as NFSv4 -- or how to debug NFS?

  - by tdn

  Problem description I have a file server running Debian. On it I have a few NFS shares. When I mount the shares from a client using NFSv3 (mount.nfs 10.0.0.51:/exports/video /mnt -o vers=3,soft,intr,timeo=10), it works. However, I would like to use NFSv4 because of improved security and performance. When I try to mount an NFSv4 share on malbec the mount command just hangs and finally times out after 2 minutes. How do I make the clients mount the NFSv4 shares as NFSv4? How do I troubleshoot NFS? There is no information in the syslog on neither client nor server. What are any errors in my configuration? Facts: Server is corvina(10.0.0.51) Client is malbec(10.0.0.1) Malbec runs Ubuntu 12.04 Server runs Debian 7 wheezy Both are connected through 1 GbE LAN.

• SSAS: distribution of measures over percentage

  - by Alex

  Hi there, I am running a SSAS cube that stores facts of HTTP requests. The is a column "Time Taken" that stores the milliseconds a particular HTTP request took. Like... RequestID Time Taken -------------------------- 1 0 2 10 3 20 4 20 5 2000 I want to provide a report through Excel that shows the distribution of those timings by percentage of requests. A statement like "90% of all requests took less than 20millisecond". Analysis: 100% <2000 80% <20 60% <20 40% <10 20% <=0 I am pretty much lost what would be the right approach to design aggregations, calculations etc. to offer this analysis through Excel. Any ideas? Thanks, Alex

• Using clang to analyze C++ code

  - by aneccodeal

  We want to do some fairly simple analysis of user's C++ code and then use that information to instrument their code (basically regen their code with a bit of instrumentation code) so that the user can run a dynamic analysis of their code and get stats on things like ranges of values of certain numeric types. clang should be able to handle enough C++ now to handle the kind of code our users would be throwing at it - and since clang's C++ coverage is continuously improving by the time we're done it'll be even better. So how does one go about using clang like this as a standalone parser? We're thinking we could just generate an AST and then walk it looking for objects of the classes we're interested in tracking. Would be interested in hearing from others who are using clang without LLVM.

• Is there a log file analyzer for log4j files?

  - by Juha Syrjälä

  I am looking for some kind of analyzer tool for log files generated by log4j files. I am looking something more advanced than grep? What are you using for log file analysis? I am looking for following kinds of features: The tool should tell me how many time a given log statement or a stack trace has occurred, preferably with support for some kinds of patterns (eg. number of log statements matching 'User [a-z]* logged in'). Breakdowns by log level (how many INFO, DEBUG lines) and by class that initiated the log message would be nice. Breakdown by date (how many log statements in given time period) What log lines occur commonly together? Support for several files since I am using log rolling Hot spot analysis: find if there is a some time period when there is unusually high number of log statements Either command-line or GUI are fine Open Source is preferred but I am also interested in commercial offerings My log4j configuration uses org.apache.log4j.PatternLayout with pattern %d %p %c - %m%n but that could be adapted for analyzer tool.

• <100% Test coverage - best practices in selecting test areas

  - by Paul Nathan

  Suppose you're working on a project and the time/money budget does not allow 100% coverage of all code/paths. It then follows that some critical subset of your code needs to be tested. Clearly a 'gut-check' approach can be used to test the system, where intuition and manual analysis can produce some sort of test coverage that will be 'ok'. However, I'm presuming that there are best practices/approaches/processes that identify critical elements up to some threshold and let you focus your test elements on those blocks. For example, one popular process for identifying failures in manufacturing is Failure Mode and Effects Analysis. I'm looking for a process(es) to identify critical testing blocks in software.

• codes to convert from avi to asf

  - by George2

  Hello everyone, No matter what library/SDK to use, I want to convert from avi to asf very quickly (I could even sacrifice some quality of video and audio). I am working on Windows platform (Vista and 2008 Server), better .Net SDK/code, C++ code is also fine. :-) I learned from the below link, that there could be a very quick way to convert from avi to asf to support streaming better, as mentioned "could convert the video from AVI to ASF format using a simple copy (i.e. the content is the same, but container changes).". My question is after some hours of study and trial various SDK/tools, as a newbie, I do not know how to begin with so I am asking for reference sample code to do this task. :-) (as this is a different issue, we decide to start a new topic. :-) ) http://stackoverflow.com/questions/743220/streaming-avi-file-issue thanks in advance, George EDIT 1: I have tried to get the binary of ffmpeg from, http://ffmpeg.arrozcru.org/autobuilds/ffmpeg-latest-mingw32-static.tar.bz2 then run the following command, C:\software\ffmpeg-latest-mingw32-static\bin>ffmpeg.exe -i test.avi -acodec copy -vcodec copy test.asf FFmpeg version SVN-r18506, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-memalign-hack --prefix=/mingw --cross-prefix=i686-ming w32- --cc=ccache-i686-mingw32-gcc --target-os=mingw32 --arch=i686 --cpu=i686 --e nable-avisynth --enable-gpl --enable-zlib --enable-bzlib --enable-libgsm --enabl e-libfaac --enable-pthreads --enable-libvorbis --enable-libmp3lame --enable-libo penjpeg --enable-libtheora --enable-libspeex --enable-libxvid --enable-libfaad - -enable-libschroedinger --enable-libx264 libavutil 50. 3. 0 / 50. 3. 0 libavcodec 52.25. 0 / 52.25. 0 libavformat 52.32. 0 / 52.32. 0 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0. 7. 1 / 0. 7. 1 built on Apr 14 2009 04:04:47, gcc: 4.2.4 Input #0, avi, from 'test.avi': Duration: 00:00:44.86, start: 0.000000, bitrate: 5291 kb/s Stream #0.0: Video: msvideo1, rgb555le, 1280x1024, 5 tbr, 5 tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Output #0, asf, to 'test.asf': Stream #0.0: Video: CRAM / 0x4D415243, rgb555le, 1280x1024, q=2-31, 1k tbn, 5 tbc Stream #0.1: Audio: pcm_s16le, 22050 Hz, mono, s16, 352 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 224 fps=222 q=-1.0 Lsize= 29426kB time=44.80 bitrate=5380.7kbits/s video:26910kB audio:1932kB global headers:0kB muxing overhead 2.023317% C:\software\ffmpeg-latest-mingw32-static\bin> http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6 then have the following error when using Windows Media Player to play it, does anyone have any ideas? http://www.microsoft.com/windows/windowsmedia/player/webhelp/default.aspx?&mpver=11.0.6001.7000&id=C00D11B1&contextid=230&originalid=C00D36E6

• Which mediacenter appliance

  - by Guillaume

  I'm looking to buy a mediacenter appliance, but I am a bit lost by all the offers on the market. Here are the features I am looking for : at least 500Go HDD capable of playing HD (1080p) supporting a good range of video and audio codecs support for subtitles including a DVB-T input (coax) and tuner composite video input 5.1 (or 7.1) analog audio output LAN (100M or Gigabit) fileserver (SMB or NFS) remote control possibly digital output (S/PDIF, TOSLINK, or other) no need for integrated DVD player no need for wifi The Ultio Pro looks nice (http://www.thinkgeek.com/electronics/home-entertainment/d3fe). It just lacks a DVB-T input which is a show killer for me. Thanks for your suggestions.

• Split section of video with ffmpeg

  - by Rob

  I've been trying to get this to work and I'm really close, but something still isn't right. I have a 14 second clip I'm trying to cut out of a longer mp4 video. I got the video to cut to the right place with this command: ffmpeg -ss 00:05:13.0 -i ~/videos/trim_me.mp4 -vcodec h264 -acodec copy -t 00:00:14.0 ~/videos/trimmed.mp4 If I didn't specify -vcodec it was starting from an "I-Frame" (I guess) and wasn't the right place. The audio is starting from that spot as well, so I tried setting -acodec the same way: ffmpeg -ss 00:05:13.0 -i ~/videos/trim_me.mp4 -vcodec h264 -acodec aac -ac 2 -ab 225k -ar 48000 -strict -2 -t 00:00:14.0 ~/videos/trimmed.mp4 Which doesn't really help much. Setting -async 1 makes it take longer, and then the audio does match up, but not until 4 seconds into the video. :/ I'd ideally not like to install anything else and have a commandline solution for this.

• Command line tool to write flac, ogg vorbis and mp3 id3v2 tags?

  - by burzum

  Is there any command line tool that can write all three formats/containers? I've already searched but could not find anything that does the job. So far I'm using vorbiscomment, metaflac and id3tool and I really would like to replace them by a single tool if possible. If there is no tool than can write them all, is there at least any suggestion to replace id3tool with something that can write id3v2 (v2.4) tags at least? I'm not looking for a tagger but for a tool that will allow me to write meta data by a script to the different audio files. My current status is that I have a script that uses the three tools (vorbiscomment, metaflac and id3tool) but then i realized that id3tool can not write id3v2 tags... I'm creating automatically these 3 audio formats from a wav master and need to be able to automate the meta data writing to these files.

• Streaming flash video does not work on my Mac OS X

  - by dehmann

  Flash videos do not work properly on my Mac. On this Vimeo video, for example, it shows only the beginning frame, and audio stutters like crazy, playing audio for a quarter second or so, then silence, then playing again, etc. I have Flash version 10,0,42,34 on Mac OS 10.5.8. It's a PowerBook G4 (PPC). I tried it in Firefox 3.5.5 and Safari 4.0.3. I tried reinstalling Flash, restarting the computer, and using a fresh user profile in Firefox (so that no extensions are interfering with the site), loading the video fully before playing, but nothing helps. I noticed that youtube videos work better, once loaded enough, although the picture does halt briefly once every 10 or so seconds, even when it's fully loaded.

• Music player alternative to windows Media Player

  - by patjbs

  I find the UI and general usability of the prepackaged windows Media Player to be cludgy and at times incomprehensible. I used to use programs like WinAmp and Sonique, many years ago. What are some current alternatives to the windows Media Player? I don't have iTunes - I'm pretty happy with ripping my own audio files from my album collection. I'm specifically looking for the follow qualities/abilities: Easy sorting and manipulation of the media library Easy tagging of media - marking favorites and ratings, etc. Preferably lightweight. Something like a Picasa for audio media.

• Managed language for scientific computing software

  - by heisen

  Scientific computing is algorithm intensive and can also be data intensive. It often needs to use a lot of memory to run analysis and release it before continuing with the next. Sometime it also uses memory pool to recycle memory for each analysis. Managed language is interesting here because it can allow the developer to concentrate on the application logic. Since it might need to deal with huge dataset, performance is important too. But how can we control memory and performance with managed language?

• ibm 8305-29u Sound comes from internal speaker instead of green port - Ubuntu 10.04 LTS

  - by TecBrat

  The title pretty much says it all. My experience w/ubuntu is VERY limited. I did find the system test feature and ran an audio test. It found my device as Intel 82801DB-ICH4. I wasn't getting anything. I tried a couple of things and don't really even remember what I tried, but I started getting audio (not just beeps) from the system's internal speaker. Any ideas? (I can't rule out a hardware problem. This box sat under my bed for a couple of years and it's first life was in an environment FULL of cement dust.)H

• powertop keeps telling me to turn off the same thing, over and over

  - by Rory McCann

  I am running an ubuntu lucid laptop on battery. I want to make my power last as long as possible. Aswell as the normal things like turn down screen brightness, and turn off wifi, I'm using powertop. It will sometimes tell me things, e.g.: Suggestion: Enable USB autosuspend by pressing the U key OK, I press the U key to do that. However a few minutes later it will give me the same suggestion, it's as if it never enabled USB autosuspend the first time. It does this for other things aswell, not just USB autosuspend. e.g. it'll give me this message frequently: An audio device is active 100.0% of the time: hwC0D1 LSI ID 1040 Q - Quit R - Refresh A - Turn HD audio powersave on Is there anything I can do to make these choices 'stick'? Or do I have some unfortunatle hardware that won't obey linux? (If so, is there any way to confirm this?)

• The best way to organize WPF projects

  - by Mike

  Hello everybody, I've started recently to develop a new software in WPF, and I still don't know which is the best way to organize the application, to be more productive with Visual Studio and Expression Blend. I noticed 2 annoying things I'd like to solve: I'm using Code Contracts in my projects, and when I run my project with Expression Blend, it launches the static analysis of the code. How can I stop that? Which configuration of the project does Blend use by default? I've tried to disable Code Contracts in a new configuration. It works in VS as the static analysis is not launched, but it has no effects in Blend. I've thinked about splitting the Windows Application in 2 parts: the first one containing the views of the WPF (app.exe) and the second one being the core of the project, with the logic code (app.core.dll), and I would just open the former project in Blend. Any thoughts about that? Thanks in advance Mike

• In MySQL, what is the most effective query design for joining large tables with many to many relatio

  - by lighthouse65

  In our application, we collect data on automotive engine performance -- basically source data on engine performance based on the engine type, the vehicle running it and the engine design. Currently, the basis for new row inserts is an engine on-off period; we monitor performance variables based on a change in engine state from active to inactive and vice versa. The related engineState table looks like this: +---------+-----------+---------------+---------------------+---------------------+-----------------+ | vehicle | engine | engine_state | state_start_time | state_end_time | engine_variable | +---------+-----------+---------------+---------------------+---------------------+-----------------+ | 080025 | E01 | active | 2008-01-24 16:19:15 | 2008-01-24 16:24:45 | 720 | | 080028 | E02 | inactive | 2008-01-24 16:19:25 | 2008-01-24 16:22:17 | 304 | +---------+-----------+---------------+---------------------+---------------------+-----------------+ For a specific analysis, we would like to analyze table content based on a row granularity of minutes, rather than the current basis of active / inactive engine state. For this, we are thinking of creating a simple productionMinute table with a row for each minute in the period we are analyzing and joining the productionMinute and engineEvent tables on the date-time columns in each table. So if our period of analysis is from 2009-12-01 to 2010-02-28, we would create a new table with 129,600 rows, one for each minute of each day for that three-month period. The first few rows of the productionMinute table: +---------------------+ | production_minute | +---------------------+ | 2009-12-01 00:00 | | 2009-12-01 00:01 | | 2009-12-01 00:02 | | 2009-12-01 00:03 | +---------------------+ The join between the tables would be engineState AS es LEFT JOIN productionMinute AS pm ON es.state_start_time <= pm.production_minute AND pm.production_minute <= es.event_end_time. This join, however, brings up multiple environmental issues: The engineState table has 5 million rows and the productionMinute table has 130,000 rows When an engineState row spans more than one minute (i.e. the difference between es.state_start_time and es.state_end_time is greater than one minute), as is the case in the example above, there are multiple productionMinute table rows that join to a single engineState table row When there is more than one engine in operation during any given minute, also as per the example above, multiple engineState table rows join to a single productionMinute row In testing our logic and using only a small table extract (one day rather than 3 months, for the productionMinute table) the query takes over an hour to generate. In researching this item in order to improve performance so that it would be feasible to query three months of data, our thoughts were to create a temporary table from the engineEvent one, eliminating any table data that is not critical for the analysis, and joining the temporary table to the productionMinute table. We are also planning on experimenting with different joins -- specifically an inner join -- to see if that would improve performance. What is the best query design for joining tables with the many:many relationship between the join predicates as outlined above? What is the best join type (left / right, inner)?

• Shoutcast admin panel not showing most of information

  - by REALFREE

  I recently start audio streaming broadcast through third party - they provide server to broadcast audio. But when I accessed Shoutcast admin panel on the server, there's not much information I can use, for example, what if I want to ban a particular ip address. Here's screen shot- And none of options did work (listeners, tail logfile, view logfile, reverse ip list.. ) does it mean that provider blocks all features on shoutcast admin panel by default? or something else.. I'd appreciate any advice. Thanks

• Is it possible to run two separate instances (copies, versions) of Audacity?

  - by cipricus

  What I want is two separate instances of Audacity running in parallel as to separate programs with different settings. I want one to use WASAPI as audio host and speakers as input device (the 2.0.5 portable has the WASAPI option), and the other to use the MME as audio host, and microphone as input device. When opening a new (second) window of the same installation/copy of Audacity, by executing twice the .exe file, it is the same as giving the command 'new' under 'File', what happens is not a second instance, but just a separate project/file and window. When settings are changed in one, they change exactly in the other. When trying to start a second copy of Audacity, or even a second different version, when one is already running, it will also open just a second project/file of the application that is already running, as before.

• Dynamic function docstring

  - by Tom Aldcroft

  I'd like to write a python function that has a dynamically created docstring. In essence for a function func() I want func.__doc__ to be a descriptor that calls a custom __get__ function create the docstring on request. Then help(func) should return the dynamically generated docstring. The context here is to write a python package wrapping a large number of command line tools in an existing analysis package. Each tool becomes a similarly named module function (created via function factory and inserted into the module namespace), with the function documentation and interface arguments dynamically generated via the analysis package.
