Boxee

2009-06-08T03:01:00.003-04:00

Here I sit, unable to sleep, watching Fantasy Island on Hulu with Boxee. Tattoo was just announcing, "De Plane! De Plane!" Tattoo is trying to convince the boss to give him his fantasy.

I haven't watched live television in about 6 months, I guess. I got a 34" 1080p HDTV around Christmas. So I built a Home Theater PC running Ubuntu 8.10 to use with it. I have a large library of movies and tv shows. So it made sense that I would organize them with the computer. As I was looking for software to do that Boxee was becoming popular. Boxee is definitely beta quality but it is headed in a fantastic direction. I wish it was better able to integrate online content with local content. But its so good there's just no point in watching live tv.

php-imap extension == evil

2009-06-04T18:14:00.003-04:00

The Problem

The PHP IMAP extension relies on University of Washington's libc-client IMAP library which appears to be written by kindergarteners. After some review of the source code, UW's IMAP client library appears to have extensive, serious security and stability problems at very fundamental levels.

I'm seeing segfaults (buffer overflows) performing simple operations like fetching attachments. Some attachments work fine but others fail; larger files especially. There are bug reports and CVE entries related to similar issues. However, upgrading to the supposed "fixed" versions of everything does not make any difference for my specific issue. It does fix some other issues related to this. (i.e. the exact same programming errors that appear to affect thousands of lines of code in the UW client.)

The Solution

Use one of the many native IMAP class library. My choice would be Zend_Mail as we use Zend Framework extensively here at work. Zend_Mail supports a number of other mail protocols in addition to IMAP. MIME type support is likely much better than other options. The other logical choice would be Pear Net_IMAP.

MySQL Master-Master-Slave(s) Database Replication

2009-04-09T11:04:00.008-04:00

I have watched the technology sessions and slideshows explaining how many large websites, such as Google or Facebook, setup their MySQL Databases. But none have ever gone into the details of how to configure MySQL in such a way. So I had to tackle that myself. I am documenting the process here so its hopefully useful to others (and myself when I forget in 6 months).

Overview of the resources involved

Server farm composed of Sun Fire x2250 servers
Sun StorageTek 2510 iSCSI storage arrays
All servers run Red Hat Enterprise Linux Cluster Suite 5.3
MySQL 5.1 from Remi has been installed (Merci Remi!)
Masters are on bare-metal with a pair of RAID-1 250GB disks, 8 cores, 16GB RAM
Slaves run as cluster services on RHEL 5.3 backed by the iSCSI arrays, 4 cores, 4GB RAM

Data Integrity Concerns
The very first thing you need to consider is that MySQL technically does not support multiple masters. This is significant because it means that there is no conflict resolution if you write data to both masters. If you happen to change the same record on both masters they wipe each other's changes out. MySQL replication works simply by replaying queries from the master on the slave server.

The safest solution is to simply never write data to both masters. Although, there are strategies that allow you to safely write to multiple masters. For example, limit writes to specific tables on each master server. In my case I use the secondary master as a replication source and hot-spare in case I need to take down the primary master for maintenance. Using the secondary master as a replication source takes the burden of slave replication off your primary database server.

Master Configuration
We have two masters. They are identified as 1 and 2. (Slaves are 11, 12, etc.)

The very first thing you should do is to run /usr/bin/mysql_secure_installation on each of your masters to set MySQL's root password and other security settings.

Master 1
Add the following to the [mysqld] section of my.cnf making the appropriate changes and restart mysqld:

# primary master server id
server-id=1
auto_increment_offset=1
# total number of master servers
auto_increment_increment=2
# local slave replication options
log-bin=master1-bin
log-slave-updates
# remote master replication options
master-host=master2.yourdomain.com
master-port=3306
master-user=replica
master-password=replic8
master-connect-retry=10

Master 2
Add the following to the [mysqld] section of my.cnf making the appropriate changes and restart mysqld:

# secondary master server id
server-id=2
auto_increment_offset=2
# total number of master servers
auto_increment_increment=2
# local slave replication options
log-bin=master2-bin
log-slave-updates
# remote master replication options
master-host=master1.yourdomain.com
master-port=3306
master-user=replica
master-password=replic8
master-connect-retry=10

Create Replication Accounts
On both master servers run the following query as root:

mysql> GRANT REPLICATION SLAVE ON *.* TO 'replica'@'%' IDENTIFIED BY 'replic8';

Dump/Load Existing Data and start Replication

On Master 1
Prevent writing to the database.

mysql> FLUSH TABLES WITH READ LOCK;

mysql> SHOW MASTER STATUS\G
*************************** 1. row ***************************
          File: master1-bin.000001
      Position: 254
  Binlog_Do_DB:
Binlog_Ignore_DB:
1 row in set (0.20 sec)

Make note of the position and file name. You must have these later. From a terminal you now need to dump the database for loading onto the slaves.

bash> mysqldump -A -u root -p > master1.sql

On Master 2
Load the data from Master 1 onto Master 2.

bash> mysql -h master2.yourdomain.com -u root -p < master1.sql

Enable Master 2 as a slave to Master 1 (refer to master 1's show master status above for MASTER_LOG* values)

mysql> CHANGE MASTER TO
MASTER_HOST='master1.yourdomain.com',
MASTER_USER='replica',
MASTER_PASSWORD='replic8',
MASTER_LOG_FILE='

master1-bin.000001

',
MASTER_LOG_POS=254;
mysql> START SLAVE;

Get the Log Info for Master 2

mysql> SHOW MASTER STATUS\G
*************************** 1. row ***************************
          File: master2-bin.000005
      Position: 12314580
  Binlog_Do_DB:
Binlog_Ignore_DB:
1 row in set (0.00 sec)

On Master 1
Enable Master 1 as a slave to Master 2 (refer to master 2's show master status above for MASTER_LOG* values)

mysql> CHANGE MASTER TO
MASTER_HOST='master2.yourdomain.com',
MASTER_USER='replica',
MASTER_PASSWORD='replic8',
MASTER_LOG_FILE='

master2-bin.000005',
MASTER_LOG_POS=

12314580;
mysql> START SLAVE;

Master-Master Setup is complete
If all you wanted was a master-master setup then you are finished. Any query executed on master 1 will also be executed on master 2.

Adding Slaves to your Master-Master

On Each Slave Follow this Procedure
Add the following to the [mysqld] section of my.cnf changing the server-id and master settings as appropriate and restart mysqld:

# this slave's server-id
server-id=11
# replicate from master 2
master-host=master2.yourdomain.com
master-port=3306
master-user=replica
master-password=replic8
master-connect-retry=10

Load the data dump from Master 1, if needed:

bash> mysql -h slave11.yourdomain.com -u root -p < master1.sql

Start Replication from Master 2 to each slave (refer to master 2's show master status above for MASTER_LOG* values)

mysql> CHANGE MASTER TO
MASTER_HOST='master2.yourdomain.com',
MASTER_USER='replica',
MASTER_PASSWORD='replic8',
MASTER_LOG_FILE='

master2-bin.000005',
MASTER_LOG_POS=

12314580;
mysql> START SLAVE;

Master-Master-Slave Setup is Complete
Congratulations, you are done with the server configuration! You may verify this by inserting or updating records on Master 1 and then verifying that the change is made on Master 1 and all of your slaves.

Client Access Considerations
To take full advantage of this configuration your client applications will need to be written in such a way that they perform all critical writes (that is, writing data that you want to keep) on Master 1. Also consider that some or all reads immediately following a write may need to come from the master. This is because it can take a few seconds for the slaves to synchronize with Master 1. This is what we call a "dirty" read. Clients performing only reads or creating temporary tables for use with those reads can access your pool of slaves and never touch the master.

Examples

Generate query-intense reports on dedicated slaves.
A portal page that doesn't need up-to-the-second data.
Statistics calculations can be performed on the slaves.

Enforcing Safe Practices
You would be well advised to GRANT only SELECT privileges to clients accessing your tables via a slave. This way a rogue client application cannot manipulate upstream data on the slave. Any changes made on the slave would not be known to any other slave nor the masters. This could be a devastatingly bad situation to find yourself in. Please think through these issues before you implement your clients.
You almost certainly will want to allow clients to create temporary tables, though.

Advanced Stuff
MySQL doesn't require slave tables to have the same schema as masters, either. This allows you to do interesting things like create your master database tables as InnoDB tables with full referential integrity and foreign keys while creating your slave tables as high performance MyISAM tables. You can create different indexing strategies on the slaves to fine-tune specific slaves to specific tasks such as report generation.

Red Hat Enterprise Linux Cluster Suite 5.2 DHCP Problems

2009-03-20T16:06:00.003-04:00

Well, I learned another valuable clustering lesson today. Manually assign all of your IP addresses and do not rely on DHCP. I'd still suggest you have the IPs statically assigned on the DHCP server but don't rely on it at all.

Yesterday I rebooted all of the machines in the cluster simultaneously after making some extensive modifications to the iSCSI configuration on them all. (I'm using cluster-ssh to manage them all simultaneously.) All of the machines went down at exactly the same time and came up at exactly the same time. (They are identical hardware with identical software, afterall.)

Today, for whatever reason, when all of the leases expired at roughly the same time they didn't renew quickly enough. I walked out of a meeting this afternoon to all of the cluster nodes reporting "Quorum dissolved" and all services on the cluster were failed.

Red Hat Enterprise Linux Cluster Suite 5.2 Relocate Problems

2009-03-11T16:58:00.006-04:00

Gist of it all
So, I've been fighting mind bending failover problems on our new compute cluster at work for the past week. I can summarize the solution to service failover problems in one sentence:
Don't use Red Hat's cluster service scripts, evar.

How it actually works
Apache's script (apache.sh) in RHEL 5.2 sends a TERM signal to Apache, waits N seconds (0 by default for Luci/Ricci, 20 for sys-config-cluster) and then proclaims that Apache has failed to shutdown if its still running. This type of failure is fatal for the cluster service.

How it should work
The standard apache init scripts (/etc/rc.d/init.d/httpd) do the right thing, more or less. The parent process is sent the TERM signal, waits 10 seconds and if its still running sends the KILL signal. That may seem harsh but this is a web server for crying out loud. There's no real chance of data corruption if you KILL the web server. If something goes horribly wrong and Apache needs to move to another machine I'm quite happy with Billy Bob having to retype a form or resume his download. That affects only Billy Bob. Bringing down the service for the entire world, in comparison, seems like a very bad solution.

Rant
Red Hat has spent years developing this clustering software. Its fairly good and seems reasonably well written. Its a shame they only spent 5 minutes writing the service scripts. The stock init scripts are infinitely better written but won't work in a clustered environment.

Solution
So, my advice, spend 20 minutes and write your own userscript for each service. If a service is important enough to be on a cluster you can afford to spend the time to write your own script to start and stop it. If you don't know how to write shell scripts and you're managing a cluster then do everyone a favor and seek employment at McDonalds.

Howto
User scripts for the cluster are simply LSB compliant init scripts. I advise you to not waste much time trying trying to hack the /etc/rc.d/init.d scripts to work within the cluster. You can do so but you'll end up stripping out most of it. You may wish to source the /etc/rc.d/init.d/functions file, though. But you will need to pass the pid filename to every single function you call. (Read the functions script to see which options to pass to each function. daemon, killproc, and status functions are most useful for starting, stopping and checking status respectively.)

Beware DVDs, CDs created on Windows Vista

2008-11-03T15:01:00.006-05:00

Windows Vista uses a new DVD/CD format that nothing else supports. So, if you are making DVDs or CDs for friends on a Windows Vista machine then your friends probably won't be able to read it unless you've manually changed the disc writer settings to "Mastered" each time you burn a disc.

This is, of course, standard operating procedure for Microsoft: Introduce some new whizbang format (documents, disks, etc) into their latest products in an attempt to force the rest of the world to use their latest software. I don't care how much better someone at Microsoft thinks it is... If the rest of the world can't read the disc its nothing more than a worthless piece of aluminum foil glued to a coaster.

Update: Ubuntu Linux 8.10 can read LiveFS formatted discs.

Well, my mother's cat "pookie" went into renal failure from diabetes yesterday. He lived a long, full life and seemed quite happy for most of it. The old guy will certainly be missed.

So long and thanks for all the fish...

Linux & Vista Slow Internet

2008-08-25T16:01:00.003-04:00

If you are seeing slow Internet speeds under Linux (2.6.17 or newer) or Windows Vista make sure your router supports RFC 1323. If it does not then this is likely your problem. To fix it, upgrade or replace your router. RFC 1323 is a performance enhancement for TCP/IP networking which LInux and Vista support. Unfortunately, it seriously hurts performance if the network hardware doesn´t support it properly (or at all).

Family

2008-07-17T12:31:00.005-04:00

Well, some family members are upset about me publishing public domain information about deceased family members exported from the 1998 Family Tree Maker CDs and federal government's master death file (aka Social Security Death Index). I'm not going to censor bits and pieces of publicly available information for one or two people. I have much better things to do with my time. So I have removed absolutely everything.

These very same people don't invite me to family events, don't let me know when loved ones pass away or if I somehow end up at a family event they make snide comments about me being there.

Its a real shame, too. I've met more family members by publicly posting old family photos than I ever met through direct interaction with relatives. Its telling that I've learned more about my family history from my father's uncle's grandson's ex-wife, whom I've never met, than my own relatives.

Peanut Butter Cookies

2007-05-27T22:46:00.000-04:00

It occurred to me that every peanut butter cookie I have ever
eaten was really dry and tasted awful.  So I
decided to try and come up with something better.

Peanut Butter Cookies

Ingredients
1 cup brown sugar
2¼ cup cake flour (not all purpose!)
1½ tsp baking powder
1 tsp kosher salt
1 cup butter-flavor shortening
¾ cup sugar
2  eggs
1½ tsp vanilla extract
1 cup peanut butter

Equipment
Ice cream scoop (or #20 disher)
2 or 3 baking sheets
Mixer

Preparation

Heat oven to 375 degrees F.
Sift cake flour, salt, and baking powder and set aside.
Combine shortening, sugar, and brown sugar and cream until light and fluffy.
Add 1 egg at a time to creamed mixture.
Add vanilla to creamed mixture.
Increase mixer speed until thoroughly incorporated.
Set mixer to low and slowly add the dry ingredients and combine well.
Add peanut butter to the mixer and mix well.
Chill the dough in freezer for about 10 minutes until it is firm but not frozen.
Scoop onto baking sheets, 6 per sheet, using an ice cream scoop or disher to maintain uniform size. The cookies need to be exactly the same size or some will burn and others will not be done. The size doesn't matter much as long as all the cookies are the same size. You can spray the disher with (butter flavor) cooking spray every few scoops to prevent the dough from sticking.
Bake for 10 minutes or until the edges turn golden brown and the center looks puffy. The cookies will spread out slightly just before they are done. Check the cookies after 5 minutes and rotate the baking sheet for even browning.
Cool the cookies for at least 10 minutes before removing them from the sheet. The center of the cookies will not look nearly as puffy once cool. Store in an airtight-container. If your container isn't completely airtight then place a slice of white bread in the container to keep the cookies moist.
Yield: 24-30 cookies
Prep Time: 20 minutes
Cooking Time: 15 minutes.

Compaq Presario 2100US & Ubuntu Linux

2007-03-18T11:06:00.000-04:00

The Radeon Mobility graphics chipset in Compaq Presario 2100US notebooks seems to have some major quirks with the "ati" X video driver. I've finally managed to find a configuration that works perfectly and enables 3D graphics support. The configuration also works with the Beryl compositor. This is tested with Ubuntu Linux 7.04.

Here is the xorg.conf configuration file I am using.

Insight/GDB debugger for Windows on Linux

2006-10-22T00:22:00.000-04:00

I needed a debugger for Windows applications which runs on Linux. After some digging around I've found that the MinGW project is maintaining the Insight debugger from the old Red Hat GNUPro Toolkit. Insight is a graphical front-end for GDB (GNU Debugger). That's exactly what I need. But I need the Windows version and I need it running on Linux.

So I've made a package named mingw32-insight for use with Debian-based Linux distributions. There's a native build of Insight provided by Debian, also. My package is wrapped in such a way that it works with the CodeBlocks::IDE development environment, also. You can find instructions on how to add a Linux to Windows cross-compiler configuration for CodeBlocks in the forums. You can install my mingw32-insight package and skip steps 7, 8, 9, 10 and 11 in the above forum posting. My package does all of that for you. My package also adds "Insight for 32-bit Windows" to your Applications -> Programming menu on the desktop.

Who knows how well this works in general. Its quite possible one could run into problems due to missing features in WINE's implementation of Microsoft Windows. But its better than nothing and exactly what I need.

Canon EOS Digital Rebel XT

2006-09-17T22:23:00.000-04:00

A few years ago I complained about problems with the original Canon EOS Digital Rebel. I'm happy to say that the newer Digital Rebel XT is a great camera and costs nearly half as much as the Rebel. Newegg has a body-only Digital Rebel XT kit for a good price.

Since I bought a kit without a lens I decided to get something a bit more versatile than the usual 18-55mm lens. So I got a Canon EF 28-105mm f4-5.6. But the Canon EF 28-105mm f3.5-4 Mark II would have been worth the extra money. It has better optics and it affords a faster shutter speed. I think my next lens would be a Canon EF-S 17-85mm f4-5.6 IS. Its much wider angle and has image stabilization to help steady the shakes.

I took some photos of insects feeding on Sedum Telephium (Autumn Joy) flowers. I believe the first is some sort of skipperling. The second is a bumblebee, of course.

Integrated Circuits - for sale or trade

2006-08-15T00:28:00.002-04:00

I have some integrated circuits available if someone might be interested in purchasing some of them or trading something for them. Have a look at the list of Integrated Circuits and send me an email if you are interested in any of them.

I don't want to get rid of all of them but in most cases I have way more than I need. I have a large number of resistors and capacitors of various types (old, new, small, large, etc) which I've not cataloged. I have some older transistors, as well. I'll post a list of transistors at some point.

Football Browser?

2006-06-18T14:27:00.000-04:00

Now there's a clever way to promote Firefox adoption... The world is filled with Football (i.e., Soccer) fans. So Google and Nike have created a community website called Joga.com dedicated to Football. But this website has a twist.

Joga works with IE somewhat. IE users can chat and do some things. More interestingly, IE users are presented with "What if your browser became obsessed with Football" advertising.

The advertisements take you to page with a screenshot of Joga Companion which only works with Firefox. Joga Companion feeds scoring and "goal alerts" in realtime for the team(s) you are monitoring. You get little popup alerts in the usual Firefox popup fashion. And there's also a video feed system built-in that allows you to watch clips of the action. It themes Firefox according to the flag of the country you are currently monitoring.

Sun + Ubuntu = Aha!

2006-05-16T23:07:00.000-04:00

About 6 months ago I commented in OpenSolaris + Ubuntu = Nexenta:

I think that Sun should take a long hard look at what Nexenta is doing and strongly consider pursuing a similar course [with Solaris]. Debian truly is the way forward. Debian provides a rock upon which all other operating systems can be built.

Perhaps that was a moment of prescience on my part. Or maybe I'm overly optimistic right now... But today Sun seems very friendly with Mark Shuttleworth, the founder of Ubuntu. Sun CEO Jonathan Schwartz and Mark Shuttleworth were on stage together at JavaONE and announced a number of important things. ZDNet reported this comment by Jonathan Schwartz,

The odds are quite good that we will be aggressively supporting the work that Ubuntu is doing...In the hardware we ship, I don't want to be Solaris only, because then I will just define my market to be smaller than the opportunity. I think you should expect to see more of the relationship, and stay tuned.

A curious project titled Nexenta was created in Canonical's Launchpad by Mark Shuttleworth a while back... Maybe it's nothing... Maybe it's something...

It's been my impression for quite a while that the Ubuntu June 2006 LTS (aka Dapper Drake) release would support the Sun Niagara hardware platform. There are mentions here or there from people working on it. Launchpad shows that SPARC support is implemented in some fashion in Ubuntu. I don't think the intention would be hum-drum SPARC support. Enthusiasm for Linux on Sun SPARC seems to have been pretty dead for the last 3-4 years. Not that it wouldn't be welcomed by many SPARC computer owners. In the past, Intel and AMD have been so much cheaper and better supported by Linux. Installing Linux on SPARC is about as painful as installing Solaris on Intel. The hardware driver support is abysmal in either case. Niagara is a different beast, though. Especially if Sun intends to help promote Ubuntu on Niagara. Niagara and Ubuntu could become a very compelling combination indeed.

But, wait, I said Linux tends to have lousy support for Sun SPARC hardware. But Nexenta is Ubuntu with a Solaris kernel... Hey, what if...Ubuntu could use the Solaris kernel and hardware drivers on SPARC (and thus Niagara). Oooh, now there's a mind bender. Keep your eyes peeled for that one... If my radar is truly working then that's exactly the sort of thing I'd expect to see. Maybe not for another release or two but certainly well before the next Ubuntu LTS (long term support) cycle begins.

Special Characters on Linux and UNIX Systems: The Compose Key

2006-05-12T23:23:00.001-04:00

Have you ever wanted to spell jalapeño correctly but don't know how? Maybe you'd like to spell dæmon a little differently? What you want is the Compose Key!

The right hand meta key is often set as the Compose key. The meta keys often have a "Windows" logo on PC keyboards. UNIX system keyboards (e.g. Fujitsu Happy Hacking Keyboard) have a diamond symbol on the meta keys. Sun Type 5 keyboards also have a separate Compose key to the right of the right meta key. Compose works with all X11 applications.

MacOS X uses the right Alt/Option key as its Compose key for X11 applications. Non-X11 applications use dead key combinations unique to MacOS X and its predecessor NeXT. (See: Apple Technical Note 2056)
