Oops - Bad DNS Update

Wed, 03 Mar 2010 11:59:00 -0500

Today I was migrating a few core services from one server to another as part of the new server build project. Basically, I need to wipe the 1st physical server and reload it with a new, different OS as part of this project. Before that can be accomplished, there are a number of services that I need to migrate to a new VM running on a different server.

Ikea Web Page Crashes Nokia Device

Wed, 03 Mar 2010 09:12:00 -0500

Today, I was doing a little online shopping using my Nokia N800. Ikea has a few price cuts on bookcases and they looked interesting, so I wanted more information.

I visited ikea.com and clicked United States – crash. Not just a browser crash, but a forced reboot of the entire device. SWEET! The N800 uses a modified Mozilla browser running a version of Linux, BTW. This isn’t a normal cell phone or otherwise limited browser. I’m not running with any special permissions either. Crashes shouldn’t be possible.

Good job Ikea. My N800 is 3 yrs old and this is the first time it has crashed to a reboot. Impressive. May I suggest you review your web site for errors?

It's Been a Busy Week - Random Thoughts

Nothing really to report this week. Doing RMA stuff on an old Antec 550W PSU and getting an estimate to fix the Dell laptop.

Survey of Typical Breakfasts

Mon, 16 Nov 2009 09:40:00 -0500

Breakfasts around the world vary greatly in my limited experience. There are differences based on eating at home, eating out, eating with friends and on holidays, in my experience. Obviously, everyone eats just a little differently at breakfast based on family, culture, and available foods in season.

American

I’m American and have lived all over the USA. I’ve found there are regional differences based on family location. Southern families might have grits with their breakfast and norther families might have oatmeal. I’ve had both, but tend towards my norther family/culture a dozen times a year or so. Most of the time breakfast at home is much simpler.

I’d guess over 30% of Americans just have something to drink for breakfast whether it is coffee of milk or juice.

Children

Cereal plus whatever else Mother can get them to eat and drink. Milk and juice and fruit, but only if cut up and put on cereal. The cereal usually has tons of sugar – Captain Crunch was my favorite as a child, but Cocoa Krispies and Life were fine. The bowl was always more than 1 cup, usually 2-3 cups. Raisin Bran became a staple after age 16 thru to my mid-30s.

Healthier Adult

Coffee, juice, some kind of fruit and a fairly small bowl of grainy cereal.
An alternative is tea/coffee, fruit, and some protein like an egg / bacon / sausage. I’m a protein, fruit, tea guy.

Special Occasions

When out with family or friends, going to a restaurant for breakfast usually means a waffle/pancake, eggs, and sausage/bacon ordeal. I usually get an omelet with almost every type of veggie and ham.

For holidays, my family has old German recipes that mix eggs, bacon, bread, and cheese all together and bake it. The sodium level will give anyone a heart attack, but it is sooooo good. About once a year, I’ll make gooey cinnamon rolls. There are also the odd times when donuts are purchased.

Japanese

I’ve heard the normal Japanese breakfast is a raw egg over a small, cold bowl of rice with green tea. I’ve tried this and found it unsatisfying. I suspect the Egg McMuffin is popular in Tokyo.

Chinese

On multiple occasions while in China, I’ve eaten breakfast out with the locals. Cantonese breakfast tends to be a hearty bowl of soup with veggies and meat. Of course, a western-style breakfast is available too, but 80% of the diners that I saw were having that big bowl of soup. Even the American chain, KFC, sells the potato + sausage soup in China. Further, it is really tasty.

Of course, if you go to a place known for dim sum, you’ll see that instead. It is definitely popular with a huge list of options on the ordering pad you will be provided with. Just check the boxes and enter the number you’d like for each available type. Ask for the English menu if it isn’t automatically provided.

Central American

Varied just like in America – French toast some days, but there’s always, always fresh fruit – papaya, cantaloupe, banana, and varied juices with coffee. Hash brown potatoes or other locally fried starches (banana) were also provided a few times. I’ve never eaten so much and so many varied fruits in a single meal, yet it probably had only 200 calories.

Metro-South American

Coffee and a small scone. I don’t know if this is typical, but while in BsAs for a few weeks, every corner had a coffee cafe that provides this. Seeing a Starbucks here is odd since the locals have known excellent coffee for their entire lives and laugh at people going to Starbucks. Starbucks is losing money, big time.

The oddest thing I found here was that carbonated water was often provided with coffee. Agua con gas or agua sin gas_. Interesting. Argentina has some specialized menus that make ordering breakfast a challenge.menus I guess the good news is that you were probably out until 3-4am drinking after eating dinner around 11pm, so breakfast isn’t really that important.

French

Coffee and croissant. My experience was on my first trip to Tokyo while spending a few weeks in a French hotel. The first week there, the company CEO and I met for breakfast in the main lobby and he loved it. On subsequent trips I stayed in the same hotel, but discovered a different breakfast was available downstairs for the same cost – about US$23. Good thing the client was paying for everything.

British

I’ve never been to Britain, but I have seen their influence in China and Japan. Thank GOD for the Brits, or I would have starved in Japan. A proper British breakfast was provided in every hotel I’ve stayed at in either place. It was usually buffet style with bangers, bacon, eggs (3 styles), fruit, and pastries.

Eating Bangers and Mash for breakfast in Hong Kong Central while watching an American Football Superbowl at 7am is a trip highlight that I’ll never forget. Since football was on TV and the expat pub, Bulldogs, was full of Americans (overflowing), Budweiser and Coors beer was available too, but paying import prices for bad beer doesn’t make sense when Carlsberg is available cheap.

Away from Home

When I’m away from home, I tend to relish in the differences and take a little of the best things back home. These turn into habits. Breakfast was some of the best experiences that I’ve had every where in the world.

Whether in an MTR station Le Madelene’s in Kowloon eating sausage soup with veggies or on Macau Island having 20 different dim sum portions or a simple home made French toast in a mountain-side home in the Monteverde Rain Forest or a Café Doblo con leche in a Buenos Aires corner Cafe, any of these experiences beats standing in my kitchen chowing on a hard boiled egg and banana as I wait for coffee or tea to steep.

When away from home, breakfast is usually a meal you can find something tasty, yet local, that will get you going for the rest of the busy day. Breakfast doesn’t usually come with the unusual-to-me or you want me to eat what concerns either.

What have been your experiences with breakfast around the world?

VMware All-Day Event Today

Thu, 05 Nov 2009 08:00:00 -0500

I’m off to the VMware event in a few minutes. It is probably more of the same. I did hear from a coworker that a 17 server VMware migration went well last night. I had nothing to do with it.

Look for me at the Georgia World Congress Center today. I’ll be wearing a dull green windbreaker if it is chilly.

If I learn something ground breaking, I’ll create a new post. Sadly, it will probably be more of the send us money and send NetApp money all-day-adware.

Typo Blog Front Page Stuck

Sat, 31 Oct 2009 09:47:00 -0400

So, a few of you may have noticed that the front page to this blog hadn’t been updated in about a week, then suddenly, there were a bunch of articles. RSS users didn’t see any issues. You really, really should use the RSS feed.

So, I searched around a little and didn’t find anything that worked. Eventually, I decided to drop into the IRC support area and asked my question:

<me> Typo 5.3 has stopped displaying recent artcles on the main page.
[09:45] <neuro`> damn
[09:45] <me> RSS feeds are fine.
[09:45] <neuro`> remove the cached index.html manually
[09:46] <neuro`> then run rake sweep_cache
[09:46] <me> tmp/cache is empty.
[09:46] <neuro`> public/index.html
[09:47] <me> THANKS.

Then I did what he suggested and everything seems to be working again. Less than 2 min. There were about 10 people in the channel. Talk about support.

Simple Audio Playback Script

Sat, 31 Oct 2009 09:00:00 -0400

Below is a script that will playback a group of audio files in order, grouped by day. Suppose you have files named like this



File-1×01.mp3

   .

File-1×12.mp3

File-2×01.mp3

   .

File-2×10.mp3

File-3×01.mp3

   .

File-3×10.mp3

   .

File-7×10.mp3

File-8×01.mp3

   .

File-8×10.mp3

and want to play group Yx1-6 followed by group Yx6-12 daily. If you just wanted to do this for 1 set of files, it would be easier to just use `at` to play them. But you might have 10-50 files like this and only want to worry about setting up playback once a month or so.

Here’s the bonehead shell script that I’m using to accomplish this.



#!/bin/sh

	Program to playback  audio tapes in order
	based on day of the month – best to start on 1st.

#
	It isn’t pretty, but it works assuming you want to cover
	half a lesson each day. The filenames look like this:
	
	File-8×10.mp3

MP=/usr/bin/mplayer

DIR=/Data/Audio/Session1

FILE_ROOT=File

DATE=`date “+%d”` # Returns the day of the month

ODD=`expr $DATE % 2`

START_GRP=`expr 1 + $DATE / 2` # pick a start date

ODD_START_NO=“01 02 03 04 05 06”

EVEN_START_NO=“06 07 08 09 10 11 12”

FILE_EXT=mp3

	Changing the 0 to a 1 will toggle which group of files to begin

if [ $ODD = “0” ] ; then

  START_NO=$ODD_START_NO

else

  START_NO=$EVEN_START_NO

fi

for count in $START_NO; do

   afile=“$DIR/$FILE_ROOT-${START_GRP}x$count.$FILE_EXT”

   if [ -f “$afile” ] ; then

      $MP “$afile”

   else

      echo " File missing: $afile"

 fi

done

exit;

So, it isn’t very pretty and it is dependent on starting the script on the first of the month. Since today happens to be Oct 31 and I just finished the first group, I tweaked the EVEN/ODD and date modulus to jump 1 day ahead tomorrow – Nov 1. It will fail when a month roles over to the next month.

A fix to that problem would be to convert the date into a Julian day of the year, DOTY, and subtract off the current DOTY from the starting date. Check out date "+%j" for more on Julian dates. Of course, then it will break at the new year, so perhaps getting the number of seconds since epoch and performing calculations based on that would be even better? Even that method will break in 2038. At some point, the complexity outweighs the difficulty to implement.

Lastly, we need to setup crontab to run the script, playing the file.

Expiration of CrossOver Linux Professional Support

Thu, 29 Oct 2009 06:13:00 -0400

Last year, the owner of CodeWeavers, a commercial Windows Interface Layer for Linux called CrossOver-Office, was forced to backup his President Bush hate speak with a fairly large software giveaway. I don’t recall the exact bet he made, but something like I’ll give my products away if any of these 3 things happen. One of them was related to the price of gasoline. At least one of them did happen and he manned up and gave away his products for a few days or weeks. WINE is the free version of this product, just a few months or years behind on compatibility.

Anyone could get a copy, installed it on their Linux machine and use it with support for a year. I did this things, but only used it a little. Perhaps … er … twice. I never used them again. I don’t recall why I didn’t use them more now. Perhaps it was that if every windows program didn’t work or didn’t work perfectly under CrossOver Office, so I still needed to keep a Windows VM anyway. Regardless, it never crossed my mind to use CO.

This morning, an email arrived with a reminder that support was ending in about a week. I should renew my support, if I want the new versions that are coming out soon. I suppose I should go down load the current versions (it has been a year after all) and install them and see if the improvements help with the Windows programs that I use and would like to use under Linux. Those are:

Quicken 2009
Investors Toolkit
MS-Office 2007
MS-Visio 2007
then I have a bunch of Windows-only computer secure tools and network scanning tools.

If you work in a structured environment with very specific tools that don’t change very often, you could and should install these tools to validate how well they work. There’s a real savings in using them across an enterprise. but note that patching may not be possible.

I’ll need a Windows VM for the other tools, so I probably won’t remember to use CO. Further, since there is no way to portable install MS-Office, it is a hassle to install it under multiple instances and it could be in violation of the license agreement. I do own an MS-Office 2003 license and work provides an MS-Office 2007 license, so being legal isn’t a problem, provided I don’t install the same version in both places. Sadly, we’ve standardized on 2007 and 2003 won’t read the new file formats. OpenOffice, which runs ever where, does a fairly good job with all the new formats, provided you aren’t collaborating and constantly going back and forth with others. It really would be easier to standardize on OpenOffice. Seriously.

Alfresco Atlanta Meetup

Wed, 28 Oct 2009 19:45:00 -0400

On Tuesday and Wednesday this week, there were a few Alfresco Meetups in Atlanta that I attended.

Tuesday was just a few hours to begin the organization of the informal group. Wednesday was an all day event with sponsors, presentations, and vendors. For what each of these were, they were well organized and cut to the core for experienced Alfresco users and developers.

My main takeaways were:

There is no upgrade path from v2.9b —> v3.×. v2.9x was a dead development tree.
If you aren’t a paid, enterprise customer and elect to use the 1 or 2 suggested community edition releases, you are on your own. Sometimes the company chooses to drop community releases. When I asked for suggestions to ensure we weren’t caught again with no upgrade path, there was no answer, just silence.
Alfresco is a Java Application running on Tomcat (by default). It is just a normal Tomcat app, so if you want to customize it, you’ll be best served by Java development. Some fairly trivial view modifications may be possible with view changes using the template engine that Alfresco uses. However, I’d never heard of this markup – must be a java thing.
Alfresco is an impressive OSS product that competes with many commercial applications that charge $50K – $1.5M for deployment licenses, They make money by selling enterprise licenses and providing support contracts. Deployments are usually performed (98% of the time) by VARs. This means they need to concentrate on supporting paid customers and may trial different techniques on the Community Edition. Sometimes it isn’t very stable and sometimes core functions are broken in the community edition.
Most of the attendees were using the enterprise version or were VARs who, by contract, were only allowed to deploy the enterprise version. If you are an Alfresco Partner, I understand you cannot support the community edition for your customers.
If you deploy Alfresco, think of it as a content container back end, not a complete solution unless everything you see out of the box is exactly what you want. Almost every user of the tool creates customizations for their environment.
CMIS is an emerging standard for communicating with ECM, DMS, WCM systems. A number of vendors have signed up. Alfresco is saying it is like SQL for content management systems. Both RESTful and WSDL interfaces are provided with this standard and it should allow customized front ends to communicate using a standard language to CMS back ends regardless of vendor. EMC, IBM, Microsoft, SAP, and Alfresco were listed as backers.
The Alfresco folks were really nice, but couldn’t really help me. This community appears to be made up of folks that do ECM for their primary jobs and not just 1/20th of their responsibilities like me.
Alfresco is an extremely capable platform, mainly suitable for normal DMS requirements. Less so for WCM based on the Best Practices session. The BPM parts appear to be very powerful, but only when you customize with Java.

I plan to stay 1 revision behind the currently recommended Alfresco release. So, right now, v3.2r is recommended. That means I’ll be re-deploying v3.1 when I get around to dropping the current install and re-importing.

I was in way over my head with all levels of the conversation. The terms used were Alfresco and java specific, neither of those are my skill set. What I need is a newcomers’ introduction to Alfresco, Best Practices for the FOSS version, and how to determine when it is time to pay for the enterprise supported version.

I wrote this summary quickly as a dump when I got home and didn’t proof it. Some of it could be inaccurate to what actually happened. I am prone to selective memory when I’m frustrated.
