It turns out that in Ubuntu 10.04, /etc/pam.d/common-session{,-noninteractive} does not contain:

session required pam_limits.so


Adding that, solved my issue:

Unfortunately, the only decent Postfix stats aggregators I could find were written in Perl (pflogsumm.pl) and consumed log files for some ad-hoc stats generation. Though, I was quite lazy after trying a few variations and finding the same Perl tools over and over so please leave a comment about your favorite Postfix stats aggregator.

I really didn’t need anything too fancy so I decided to take a stab at it myself. After thinking about it for a few minutes, I decided to try out using Python threading to have a small pool of workers run some regex on a queue of lines from syslog. All the stats are then gathered in a dictionary and either spit out to stdout or there is a VERY simple TCP server thread listening for ‘stats’ or ‘prettystats’ to dump the current cumulative stats as a JSON dictionary. Full readme can be found on the Github page. Best part, it requires no 3rd party libraries.

Wrong! After some amount of time, it just sits at 100% CPU and no longer processes tasks. Unfortunately, Celery calls monkey_patch a little late when coupled with Django. Django does some magic of its own to various components so monkey_patch needs to be called before Django does any initialization. After a little digging, I found I can just set an environment variable to prevent Celery from doing the monkey patching and at the same time use it to signal manage.py to call monkey_patch before the initialization my Django app.

Just add this to the top of your manage.py:

if os.environ.get('EVENTLET_NOPATCH'):
    import eventlet
    import eventlet.debug

    eventlet.monkey_patch()
    eventlet.debug.hub_prevent_multiple_readers(False)

    eventlet_timeout = os.environ.get('EVENTLET_TIMEOUT')
    if eventlet_timeout:
        eventlet.debug.hub_blocking_detection(True, float(eventlet_timeout))

Now when starting celeryd just add the environment variable EVENTLET_NOPATCH='yes' to your manage.py command

EVENTLET_NOPATCH='yes' python ./manage.py celeryd -c 1000 -Q eventlet_tasks -P eventlet


Also, if you’re worker seems to be running a little slow, you can now add EVENTLET_TIMEOUT='1.0' to cause Eventlet to print a stacktrace of the blocking thread to stderr. hub_blocking_detection takes a float in number of seconds to set the alarm for.

EVENTLET_TIMEOUT='0.1' EVENTLET_NOPATCH='yes' python ./manage.py celeryd -c 10 -Q eventlet_tasks -P eventlet


These steps are done on a Snow Leopard iMac (10.6.7 specifically) but I’m pretty sure they would work on a Tiger/Leopard (10.4/10.5) machine as well.

First thing is to install Soundflower which requires a restart. It’s similar to Audio Hijack Pro in the fact that it adds virtual sound devices but without any other capabilities like recording/sfx/etc (and it’s freeware).

Next you will need is AU Lab from Apple. It’s a bundled application with Xcode so either download it from Apple or install it from your OS X Install DVD if you don’t want to deal with the multi-GB download.

And that’s it for software requirements!

Step 1) Change Audio Output Device

Change the output device in System Preferences->Sound, choose the Output tab. You should see Soundflower (2ch) in the list of devices. Select that one.

Step 2) Open AU Lab

Easiest to search for it in Spotlight or it’s default location is at /Developer/Applications/Audio/AU Lab.app

Step 3) Setup Input and Output devices in AU Lab

You’ll be prompted with “Document Configuration”, use the Factory Configuration “Stereo In/Stereo Out”. Change the Audio Input Device to “Soundflower (2ch)” and the Audio Output Device to “Built-in Output”. Finally, click Create Document.

Step 4) Add EQ Effect

Under “Ouput 1″ apply the effect Apple->AUGraphicEQ

Step 5) Edit the EQ

Tweak like mad with 31 bands or change it to 10 bands to get an EQ that looks more like the iTunes one.

Step 6) Save your preset

The 3rd drop down from the left of the EQ window lets you save/change presets.

As we were setting up, those of us who already were using FiSH couldn’t tell who was talking encrypted and who wasn’t. So @noah256 brought up the idea of prefixing encrypted messages. Later he also realized this can be spoofed; so he suggested to also prefix unencrypted messages from expected encrypted targets. At the same time, we realized when trying to talk to people without FiSH installed, it wasn’t really easy to temporarily send unencrypted messages so we also added a prefix to tell the module to not encrypt the message.

I used the fish.cpp from the fish – ZNC wiki page. For now, the behavior I added is hard coded. I hope when I have free time again, to make the prefixes and disable flag to be configurable.

My modified module can be found in my znc-fish repo on GitHub

"(e) " denotes the message was received encrypted
"(d) " denotes the message was received unencrypted

If you send a message prefixed with "-e",  it won't encrypt the message.

After setting up a RAID10 array using the WebBIOS tool and installing FreeBSD I ran mfiutil show volumes to make sure I was referencing the right virtual drive and to my astonishment I see:

mfi0 Volumes:
  Id     Size    Level   Stripe  State   Cache   Name
 mfid0 (  408G) RAID-1      64K OPTIMAL Enabled

Say WHAT?! That volume is NOT supposed to be RAID1. So I ran mfiutil show config to get some more details about my configuration.

mfi0 Configuration: 3 arrays, 1 volumes, 0 spares
    array 0 of 2 drives:
        drive 8 (  137G) ONLINE <SEAGATE ST3146356SS 0005 serial=SERIAL> SAS enclosure 1, slot 0
        drive 9 (  137G) ONLINE <SEAGATE ST3146356SS 0005 serial=SERIAL> SAS enclosure 1, slot 1
    array 1 of 2 drives:
        drive 10 (  137G) ONLINE <SEAGATE ST3146356SS 0005 serial=SERIAL> SAS enclosure 1, slot 4
        drive 11 (  137G) ONLINE <SEAGATE ST3146356SS 0004 serial=SERIAL> SAS enclosure 1, slot 5
    array 2 of 2 drives:
        drive 12 (  137G) ONLINE <SEAGATE ST3146356SS 0004 serial=SERIAL> SAS enclosure 1, slot 6
        drive 13 (  137G) ONLINE <SEAGATE ST3146356SS 0005 serial=SERIAL> SAS enclosure 1, slot 7
    volume mfid0 (408G) RAID-1 64K OPTIMAL spans:
        array 0
        array 1
        array 2

Alright, that looks right but it still says RAID1 as well. Now this kind of bugs me, since I even followed the MegaRAID SAS User Guide to setup the RAID10 array. Alright, let’s get mfiutil to spit out some debug output; which requires applying a patch and recompiling.

cd /usr/src/usr.sbin/mfiutil
make clean
patch fix-mfiutil-debug.diff
make -DDEBUG
/usr/obj/usr/src/usr.sbin/mfiutil/mfiutil debug

Ok, now this looks right to me. Primary RAID level is 1 and secondary RAID level is 0.

        array 1 @ 0 : 285155328
        array 2 @ 0 : 285155328

So why is it still reporting RAID1? Well let’s dive into the source of mfiutil. Ah-ha! The issue stems from mfi_cmd.c

const char *
mfi_raid_level(uint8_t primary_level, uint8_t secondary_level)
{
        static char buf[16];

        switch (primary_level) {
        case DDF_RAID0:
                return ("RAID-0");
        case DDF_RAID1:
                if (secondary_level != 0)
                        return ("RAID-10");
                else
                        return ("RAID-1");

Well, okay then. That is only partially correct. According to Common RAID Disk Data Format Specification that is an incorrect assumption. I dug a little deeper into the issue and found this thread on the freebsd-current mailing list. The post that made it clear why mfiutil may make this assumption was by John Baldwin

Previous RAID-10 volumes that I've seen MFI BIOSes create used a non-zero
secondary raid level (they all used '3', which is what mfiutil uses to
create RAID-10 volumes itself).

John Baldwin

I found a thread on the Dell Linux-PowerEdge mailing list and according to I believe a Dell rep, saying their PERC controllers (which is based on MegaRAID) reports RAID levels based on the SNIA DDF standard. So I followed his suggestion and started reading the SNIA DDF specification I linked above.

On Page 84:

Table 15 lists values used in the Secondary_RAID_Level field of the Virtual Disk Configuration Record
(Section 5.9.1) and their definitions. The table defines secondary RAID levels such as Striped, Volume
Concatenation, Spanned, and Mirrored for hybrid or multilevel virtual disks. The Secondary_RAID_Level
field in the Virtual Disk Configuration Record MUST use the values defined in Table 15.

Table 15: Secondary RAID Levels

So now it all makes sense. The WebBIOS tool is using a secondary level of 0 because my VDs are all the same size so it has no reason to instruct the controller to use a secondary level 3. Now I don’t have to worry that I may of configured my array incorrectly.

If you want to allow more than root or wheel group members to use the command, just use this sudoers privilege specification:

ALL=(rabbitmq) SETENV: NOPASSWD: /usr/local/bin/erl


(rabbitmq) assumes your RabbitMQ broker runs as the ‘rabbitmq’ user. It also assume you have Erlang installed in /usr/local

I like to use: memcache-top --servers='server1,server2,server3' --commands --sleep=1

My only qualm is it doesn’t display the curr_items stat. So I wrote a little patch for v0.6 that will add an ITEMS column to the table.

Get the patch from the issue I filed.

Small issue with Homebrew is it seems to want to stick to ‘Stable’ releases. I really didn’t want to use MySQL 5.1 since it’s a snail compared to MySQL 5.5. Not having an ultra-fast storage array in my iMac this would become an issue with all the work I have to do. So I set out into Ruby land and banged out my first Homebrew formula.

Since it hasn’t been pulled into the official repo, here’s the latest commit: MySQL 5.5 Homebrew Formula

Mainline Homebrew now has 5.5.x as the default MySQL version

Updated: Oracle released MySQL 5.5.8; the first GA release of the 5.5 series.
