• VS2010 / Code Analysis: Turn off a rule for a project without custom ruleset....

  - by TomTom

  ...any change? The scenario is this: For our company we develop a standard how code should look. This will be the MS full rule set as it looks now. For some specific projects we may want to turn off specific rules. Simply because for a specific project this is a "known exception". Example? CA1026 - while perfectly ok in most cases, there are 1-2 specific libraries we dont want to change those. We also want to avoid having a custom rule set. OTOH putting in a suppress attribute on every occurance gets pretty convoluted pretty fast. Any way to turn off a code analysis warning for a complete assembly without a custom rule set? We rather have that in a specific file (GlobalSuppressions.cs) than in a rule set for maintenance reasons, and to be more explicit ;)

• Why do I get Code Analysis CA1062 on an out parameter in this code?

  - by brickner

  I have a very simple code (simplified from the original code - so I know it's not a very clever code) that when I compile in Visual Studio 2010 with Code Analysis gives me warning CA1062: Validate arguments of public methods. public class Foo { protected static void Bar(out int[] x) { x = new int[1]; for (int i = 0; i != 1; ++i) x[i] = 1; } } The warning I get: CA1062 : Microsoft.Design : In externally visible method 'Foo.Bar(out int[])', validate local variable '(*x)', which was reassigned from parameter 'x', before using it. I don't understand why do I get this warning and how can I resolve it without suppressing it? Can new return null? Is this a Visual Studio 2010 bug?

• remote class alias in air

  - by viv

  Hi in Flex one can easily define the remote class alias like the following: package samples.portfolio { [RemoteClass(alias="flex.samples.marketdata.Stock")] [Bindable] public class Stock { public var symbol:String; public var name:String; public var low:Number; } } But my question is how do you do it in AIR since the client app does not know about the server file structure. Regards,

• When to stop following the advice of static code analysis?

  - by bananeweizen

  I do use static code analysis on a project with more than 100.000 lines of Java code for quite a while now. I started with Findbugs, which gave me around 1500 issues at the beginning. I fixed the most severe over time and started using additional tools like PMD, Lint4J, JNorm and now Enerjy. With the more severe issues being fixed, there is a huge number of low severity issues. How do you handle these low priority issues? Do you try fixing all of them? Or only in newly written code? Do you regularly disable certain rules? (I found that I do on nearly any of the available tools). And if you ignore or disable rules, do you document those? What do your managers say about "leaving some thousand low priority issues not fixed"? Do you use (multiple) tool specific comments in the code or is there any better way?

• How can I load an MP3 or similar music file for display and analysis in wxWidgets?

  - by Jon Cage

  I'm developing a GUI in wxPython which allows a user to generate sequences of colours for some toys I'm building. Part of the program needs to load an MP3 (and potentially other formats further down the line) and display it to the user. That should be sufficient to get started but later I'd like to add features like identifying beats and some crude frequency analysis. Is there any simple way of loading / understanding an MP3's contents to display a plot of its amplitudes to the screen using wxWidgets? I later intend to port to C++/wxWidgets for speed and to avoid having to distribute wxPython.

• Rapid spectral analysis of audio file using Python 2.6?

  - by Ephemeralis

  What I want to do is to have a subroutine that analyses every 200 milliseconds of a sound file which it is given and spits out the frequency intensity value (from 0 to 1 as a float) of a specific frequency range into an array which I later save. This value then goes on to be used as the opacity value for a graphic which is supposed to 'strobe' to the audio file. The problem is, I have never ventured into audio analysis before and have no clue where to start. I have looked pymedia and scipy/numpy thinking I would be able to use FFT in order to achieve this, but I am not really sure how I would manipulate this data to end up with the desired result. The documentation on the SpectrAnalyzer class of pymedia is virtually non-existant and the examples on the website do not actually work with the latest release of the library - which isn't exactly making my life easier. How would I go about starting this project? I am at a complete loss as to what libraries I should even be using.

• Java static source analysis/parsing (possibly with antlr), what is a good tool to do this?

  - by Berlin Brown

  I need to perform static source analysis on Java code. Ideally, I want the system to work out of the box without much modification from me. For example, I have used Antlr in the past, but I spent a lot of time building grammar files and still didn't get what I wanted. I want to be able to parse a java file and have return the character position of say: Character position start and end of a Java block comment Character position start and end of a Java class file Character position start and end of a Java method declaration, signature, and implementation. It looks like Antlr will do that, but I have yet to finish a grammar that actually gives me the positions of the code I need. Does anyone have that complete Antlr grammar and Java code to give the character positions of the parts in the Java source.

• nginx points the sub-directory of an alias folder to the base directory

  - by Starry

  I am new to Nginx. Now I have a confusion on nginx configurations: My web site contains folders in different locations: location / { root /Path1 } location ^~ /personal { alias /Path2 } When I query http://mysite/personal, I am accessing the content of /Path2 instead of /Path1 Now I want to add a sub-directory in /personal with specific configurations, so I add: location /personal/download { autoindex on; } But I got 404 error when querying http://mysite/personal/download. According to the error log, I am directed to /Path1/personal/download, which is not correct. How can I configure nginx, such that all access to http://mysite/personal/* will be directed to the same directory in /Path2?

• route port 3000 to apache2 alias

  - by user223470

  I have a meteor application running on port 3000. I can successfully connect to the program with www.myurl.com:3000, but would rather connect to it via www.myurl.com/myappname. I started with the instructions on this web site: http://www.andrehonsberg.com/article/deploy-meteorjs-vhosts-ubuntu1204-mongodb-apache-proxy and I have the following Apache configuration file: <VirtualHost *:80> ServerName myurl.com ProxyRequests off <Proxy *> Order deny,allow Allow from all </Proxy> <Location /> ProxyPass http://localhost:3000/ ProxyPassReverse http://localhost:3000/ </Location> </VirtualHost> I do not know how to continue from here to get the program on www.mysite.com/myapp. In other situations, I would use an Alias within the Apache configuration file, but that doesn't seem like the right direction to go in this case. How do I configure Apache to send port 3000 to www.myurl.com/myapp?

• ${extension} empty after catch-all alias in Postfix

  - by Paul Wagener

  I want a setup where an e-mailaddress like [email protected] redirects mail to the folder foo. I've already got dovecot configured and tested. It is called by postfix with this line in master.cf: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop} -n -m ${extension} I expect ${extension} to expand to 'foo' but it is always empty. I've added recipient_delimiter = + to my main.cf. How can I get it to work? Update: I've got a catch-all alias that redirects @domain.com to [email protected]. It seems that the extension is empty because of this. So the question becomes: Can I have a catch-all so that [email protected] redirects to [email protected] without explicitly defining either the random or the ext part?

• Determine/resolve filepath/alias of a certain command in the Windows command prompt

  - by porg

  How can I find out to which filepath (or alias) a certain command input will point to, in the Windows command prompt? Specifically Windows XP, info on other versions also appreciated! On Unix systems I simply use: $ which commandname /a/commandname Or: $ type -a commandname commandname is aliased to `/b/commandname' commandname is /a/commandname commandname is /b/commandname And I am simply looking for the equivalent in the Windows Shell (specifically Win XP). I came to this general question, from a specific issue: I had installed robocopy.exe (version 026), but the command line "robocopy" always triggers version 010, and I would like to determine where this command points to, in order to correct this mistake.

• postfix "mail-pipe" alias shellscript creates permissionless files/dirs

  - by Gung Foo

  I am using an alias to a shellscript in postfix... After the script that is called by the shellscript creates a directory it has no permissions at all.. #!/bin/sh umask 002 cat | php /var/www/html/catchmymail rcvemail result is like this: d--------- 2 apache apache 4096 Sep 17 17:25 50 it works for files tho: -rw-rw---- 1 apache apache 5836288 Sep 18 11:21 test Not even setting umask 002 in the shellscript before it hands the mail on changes a thing Setting umask(0002) inside catchmymail has no effect either. Has anyone seen this behaviour before or an idea to save my day?!? This is extremely confusing and actually insane behaviour from what i understand about umask and file permissions.

• Alias multiple DNS entries to one Amazon S3 Bucket

  - by Tristan

  I have a bucket on Amazon S3. Lets call it "webstatic.mydomain.com". I have a DNS alias setup for that bucket webstatic.mydomain.com CNAME - web-static.mydomain.com.s3.amazonaws.com. This all works great, however for some rather complicated reasons I now need: webstatic.myOtherDomain.com to point to that same amazon bucket so: webstatic.myOtherDomain.com CNAME - web-static.mydomain.com.s3.amazonaws.com. Fails, as the bucket is not called the same as the referring DNS. Can anyone tell me how to have two different DNS entries pointing to the same amazon bucket?

• Sendmail Alias for Nonlocal Email Account

  - by Mark Roddy

  I admin a server which is running a number of web applications for a software dev team (source control, bug tracking, etc). The server has sendmail running solely as a transport to the departmental email server over which I have no control. We have someone who is still in the department but no longer on the dev team so I need to configure the transport agent to redirect all outgoing email (which would be coming from these applications) to the person that has taken their place. I added an entry in /etc/aliases like such: [email protected]: [email protected] But when I run /etc/init.d/sendmail newaliases I get the following error: /etc/mail/aliases: line 32: [email protected]... cannot alias non-local names So clearly I'm doing something I shouldn't. Is there a way to get aliases to work with non-local names or alternatively is their a way to accomplish my goal of redirecting outgoing mail for this user to another one? Technical Specs if the matter: Ubuntu 6.06 sendmail 8.13 (ubuntu provided package)

• Sendmail.mc: alias all incoming e-mails to one account

  - by Angus

  I need to alias all mail coming from another SMTP server to this one account "myinbox". The system in question is to receive all e-mail on the domain, if that's any help. http://william.shallum.net/random-notes/sendmailredirectallmailfordevelopment is a template for the beginning of a solution, but that routes everything (including outgoing and internal mail) to that one account, and trying to understand how these R rules work is making my head spin. I think the answer is in sendmail.mc rather than any Procmail configuration. So I think what I generally don't want the filter to do is: Interfere w/any outgoing e-mail Interfere w/any internal e-mail Sometimes some cron job causes "root" to mail to "root". I don't want these to go to myinbox. Cause infinite loops Who does? Bounce messages and any DSNs come to mind. I'm running Sendmail 8.13.1 and Procmail 3.22.

• Mod_rewrite on Alias directory

  - by crunchline

  I am moving from a WIMP setup to a WAMP setup. My images are on a separate drive. I need a default image served, when a file is not found. Currently it returns a 404 on images not found in the /images directory, and the 404.jpg is displayed for files not found on all the other directories. I tried changing [L] to [PT] but that did not do anything. in httpd.conf Alias /images "D:/images" in .htaccess RewriteCond %{REQUEST_FILENAME} !-s RewriteRule ^.*\.(gif|jpg|png)$ /404.jpg [L]

• How to setup IP alias on bridged interface in Ubuntu

  - by Anonymouslemming

  How do I setup an IP alias on a bridge (br0) device on Ubuntu ? If I wait for br0 to come up and then do /sbin/ifconfig br0:0 192.168.10.1 netmask 255.255.255.0 then it works fine. If however I add the following to my /etc/network/interfaces file, it does not work and the network fails to start: auto br0:0 iface br0:0 inet static address 192.168.10.1 netmask 255.255.255.0 At the moment, I have a script in /etc/network/if-up.d/bridge_alias that does this as follows: #!/bin/bash if [ "${LOGICAL}" == "br0" ] && [ "${PHASE}" = "post-up" ]; then echo -n "Starting br0:0 ... " /sbin/ifconfig br0:0 192.168.10.2 netmask 255.255.255.0 echo "Done!" fi What is the right way of doing this though, just using the OS network config files ?

• Cannot connect to a SQL Server 2005 Analysis Services cube after installing SQL Server 2008 SP1.

  - by Luc

  I've been developing an application that talks directly to an SSAS 2005 OLAP cube. Note that I also have SQL Server 2008 installed, so the other day I did a Windows Update and decided to include SQL Server 2008 SP1 in my update. After doing that, my SSAS 2005 cube is no longer accessible from my application. I'm able to browse the data just fine within SQL Server 2005 BI Studio Manager, but I'm not able to connect to the cube from my application. Here is my connection string that used to work: Data Source=localhost;Provider=msolap;Initial Catalog=Adventure Works DW Here is the error message I get: Either the user, [Server]/[User], does not have access to the Adventure Works DW database, or the database does not exist. Here is the beginning of my stack trace if it would help: Microsoft.AnalysisServices.AdomdClient.AdomdErrorResponseException was unhandled by user code HelpLink="" Message="Either the user, Luc-PC\\Luc, does not have access to the Adventure Works DW database, or the database does not exist."

• DNS lookup aliasing of hostnames (not IP aliases), probably via dnsmasq

  - by intuited

  I'd like to be able to set up a host, say "eg", to be an alias to some server on the internet, say "example.example.com". I just need this functionality to be available from my local machine. I'm running dnsmasq on that machine, which is running ubuntu 9.10. Is there a way to configure dnsmasq or the resolver subsystem (including avahi) to resolve that alias hostname via the actual hostname, so that eg will resolve to the ip address of example.example.com?

• Looking for an open source real-time network analysis program

  - by JrSysAdmin

  Can somebody recommend an open source real-time network analysis program? What I'm looking for the program to do is display a graph of bandwidth usage by IP within our internal network that can quickly be viewed any time we need to (typically when we want to quickly find out who is utilizing high amounts of bandwidth and slowing down the network). We ideally simply want to hook up a monitor on the wall of our server room to a system whose NIC will be in permissive mode to log all network activity in a visual manner which can easily be seen and running 24/7. Prefer open source as I do not have a budget for this project and prefer open source projects in general. I'd also prefer for this to be available for CentOS but any linux distro or Windows OS would be acceptable. Thanks!

• Eclipse CDT code analysis thinks size_t is ambiguous

  - by Chris

  It does, after all, get defined in stddef.h AND c++config.h: c++config.h: namespace std { typedef __SIZE_TYPE__ size_t; typedef __PTRDIFF_TYPE__ ptrdiff_t; #ifdef __GXX_EXPERIMENTAL_CXX0X__ typedef decltype(nullptr) nullptr_t; #endif } stddef.h: #define __SIZE_TYPE__ long unsigned int So when a file does using namespace std, the Eclipse CDT code analysis gets confused and says the symbol is ambiguous. I don't know how gcc works around this, but does anybody have any suggestions on what to do for the eclipse code analysis?
