Miscellaneous Updates for February 2008

I’m doing an extremely bad job of keeping the site fresh over the last few months or so. I figured I’d give a quick update of things going on.

I’m Still Not Smoking

I finally started the Step 3 of the Nicoderm CQ program. This one has been rough. This is where you really start physically feeling the consequences of nicotine being removed from your system. I’ve been completely exhausted for the last week. Apparently, that there nicotine is one powerful stimulant and really screws with your metabolism. Your body takes some time to equalize itself and get itself back to where it needs to be naturally. I’m hoping mine gets there soon – because I’ve not had a good time over the past week.

The interesting thing about these “stop smoking aids” is that they defer you dealing with the real issue until you have so much skin in the game that you can’t start again without feeling an intense feeling of failure. Brilliant, but I can tell you that first step gives you an overly simplified view of what it takes to quit smoking. It starts getting a little harsher at step 2 and now at step 3 you really start PHYSICALLY feeling it. The only thing worse will be when Step 3 is over and my body starts eliminating nicotine all together.

Like I said though, I have too much skin in the game now to restart – I think.

New iPhone User

Jonna bought me an iPhone for our anniversary, and I have to say that aside from the GPS she got me for Christmas, which allows me to go out by myself and still be able to get home, it is about the coolest thing for me from a productivity perspective that we have added to my highly disorganized life.

I’m finally able to get all my contact information in one place where it is accessible at any time. I can take notes, I can look things up on the web and I can check personal email. From a browsing perspective, I can get to things that are a part of my life but are blocked at the firewall at work (which is great as well). I feel free.

Now, it hasn’t been without its problems. The 1.1.3 software that came with the phone dropped a lot of calls. It wound up pretty frustrating and I kept my work supplied cell phone so that I could actually hold calls without them getting dumped. The 1.1.4 update took care of this though and now it works like a real phone.

I love the contact management included in the phone. Support for multiple numbers per contact and custom labelled information (including notes) lets me keep track of all the information I could ever want about someone. I can even attach a picture. Integration with the Mac Address book allows me to keep my contacts up to date without having to type into the phone.

And speaking of typing into the phone - I love not having to type on a standard phone keypad. The automatic spell-checking sometimes gives me a run for my money, and more often than not makes me sound retarded, like this little exchange with Jonna:

Overall though, I think between the GPS for Christmas and the iPhone this month, I’ve received the two most useful (and really most used) gifts ever.

As an aside, for those who are obsessed with not scratching or smudging their iPhone or other Apple products, Jonna also picked up a skin called Best Skins Ever for both Kelsi and myself, which we applied a couple of weeks ago. Kind of scary at first (you need to use water to apply it), but they really are the best skins ever. You don’t even know they’re there. I’m definitely going to pick up one for my iPod, as soon as I get a round tuit.

Well thats it from the Labs for last month. I’m sure as the weather starts to warm and the nicotine continues to seep out of my system, I’ll have more energy to blog about useful things.

Breathing Room

My recent upgrade to an 80G iPod gives me way more breathing room than I had with the 20G, and I can finally carry family photos around to boot!

Building Scalable Web Sites by Cal Henderson

I have about three books that I am reading on and off but have been unable to focus on any of them for any length of time. Tom The Architect mentioned a book to me a few months ago called Building Scalable Web Sites: Building, Scaling, and Optimizing the Next Generation of Web Applications by Cal Henderson, engineering manager for the Flickr photo service, a service that I have used extensively since being turned on to it by, you guessed it, Tom The Architect.

This was the first book in a long time that I couldn’t put down, mainly because everything in the book is geared towards teaching you about how to create really, really, big web sites and the issues involved in scaling them. It was also quite intriguing because the book covers tools you use all of the time, like PHP and MySQL that are hard to find really good books about how they scale.

Cal covers a lot of material in this book, from layering your web application architecture, to creating an environment for developers to work in, which includes source control, issue tracking, coding standards and the like. This section was quite encouraging to me, as we have implemented almost everything that Cal mentions in the book (sometimes its nice to get some external validation). Cal then goes on to talk about internationalization and localization, data integrity and security, using email as an alternate entrance into your application, and how to build remote services.

All of this was great, but the next few chapters I found really valuable. Cal talks about identifying bottlenecks in your web application, scaling applications such as MySQL (where he covers quite a few replication strategies) and scaling storage. He also covers measurements, statistics and monitoring. Finally, Cal talks about adding API’s into your application to support mobile applications, web services, etc.

Cal references quite a few tools that are freely available in these discussions - tools that I didn’t even know were out there, that you can use to simplify your monitoring environment. I was most intrigued with the Spread Toolkit, a self described “a unified message bus for distributed applications” that allows you to unify logging across your applications. Anyone who has tried to debug an issue on a site that has more than one box would appreciate knowing about this tool.

This is the first book that I’ve read in a long time, technology wise, that hit the sweet spot between talking about real issues that I have been facing and possible solutions. I highly recommend grabbing this book and in the very least just keeping it on your book shelf for future reference. This is one thats going to be a constant companion for me in the coming months.

iTunes Music Store Faster on a Mac?

I’ve been meaning to throw this question up here for a while. Is it just me, or is the iTunes Music store a hell of a lot faster on a Mac than it is on Windows?

While I like the convenience of iTunes, I absolutely dreaded hitting the music store on my Windows machine. It felt like it took forever to get any decent results. Since moving to the Mac though, the Music Store responds extremely quickly and I have no qualms about doing searches and browsing around now.

I’m just curious - has anyone else that has both types of machines noticed this behavior, or is it just my mind playing tricks on me?

iTunes Finally Converted to MacBook

Well, after about two days of file copying, I finally got all of my iTunes stuff moved over to the new Mac. Why did it take so long you ask? I’m not really sure.

Copying between the Windows box and the MacIntosh using Windows File Sharing just didn’t work unattended. It kept failing for some reason. After about three tries at that, I decided to install cwRSync so that I could restart incrementally, but for some reason, this would not run unattended either, and I didn’t want to spend forever running back and forth between the family room and the living room (where my desk is).

Finally I decided to copy my iTunes library up to the Linux server. I started it at about 7:00am and by 7:30-8:00pm on Tuesday the file copy had completed with no interruptions. On Wednesday, I started an rsync from the Linux server to the MacBook. Another 12 hours later and that was complete.

I had heard horror stories about moving this stuff around if you had purchased music and was a little worried that I would have to spend a lot of time getting the machine authorized and stuff like that. Not so. As a matter of fact, I found these instructions on moving your iTunes library with metadata and they worked without a hitch. I now have all of my music on the MacBook. Nice!

I really do like this environment a lot better than anything I’ve used in the past. I’m not clear as to why I had all of the copy failures I had from machine to machine, but thankfully I’ve got the trusty SuSE server to back me up.

Its the little things you notice …

Now that I have a few days on the Mac using it full time, I figured I’d post up some first impressions from a new user. More than that, observations from a new user who resisted the Mac when all his friends told him to go that way in the first place.

When the light in the room gets too low, the keyboard lights up. At first glance this seems completely insignificant, but again, one of those little things that shows the care that goes into the design. It was definitely a pleasant surprise. In a normal company, something this “frilly” would have been cut to remove costs - but as a customer I was absolutely delighted by it.
I like not having a key on the keyboard for every little thing. The modifier key thing is totally working for me for page up / down, etc. Its extremely intuitive once you figure it out (and it doesn’t take long to figure it out).
Using two fingers to scroll with the mouse. Tom the Architect told me about this one. Much more intuitive than a touchpad with the right side dedicated to scrolling.
For years I’ve been irritated with people turning auto hide on the Windows taskbar. For some reason, auto hide makes sense to me with the dock bar. Not sure why, but the whole metaphor of the docking bar works for me on levels that I couldn’t get with Windows
I love the idea of one menu at the top of the screen, rather than a menu in every application. This also works for me on a number of levels.
The overall look of things on the screen is beautiful compared to my Gateway box. Same applications, completely different feeling when looking at them.
Installing software is really a brain dead process. Its the way software should work. On the other hand, I’m going to have to get used to not needing so much detail to get something working. I think I’m finally at the point where I’m ok with this. Must be a sign of getting old.
There is absolutely no need for a “View Full Screen” option on any of these applications. I have enough of the application visible whenever I need it. I can even collapse the top of the window to get more room. Its a little thing, but another one of those “Wow” moments.

Overall, I’m completely impressed. While my initial resistance to going Mac had a lot to do with the price, there are so many little things that I’m finding that are valuable enough to make me feel better about the purchase price. You get what you pay for and I’m quite happy with the new purchase.

The Flickr vs. Zoomr Thing …

I was really glad to read Stewart Butterfields response to the whole Zoomr API key thing that happened over the weekend.

The first thing I thought of when hearing about the hub-bub first on Tom the Architects blog and then on yesterdays Geek News Central (I’m a little behind lately) was the article Strategy III: Let Me Go Back by Joel Spolsky. I think that the essay does a really good job of illustrating the huge barrier to entry that the ability to choose to leave can be to a customer looking to use a product or service.

For me, the attitude of not allowing competitors to access public API keys seemed way too “lock in” like for even me, a very loyal Flickr user. I know that some of the arguments floating around places like TechCrunch were things like “why should Flickr let Zoomr use their bandwidth to take their customers”. The main reason for this is because they chose to create a public API and cannot discriminate against competitors without looking petty and protective.

This is a hard thing for companies to learn. Customers don’t want it to be a hard thing to leave your site or product. It’s a powerful feeling to know that you can move somewhere to try out a service and if it doesn’t work for you — you can leave. At different times in my career I’ve watched people confuse the idea of “creating stickiness” with the idea of tying the customer to a particular product — or at least making it hard for them to leave — and its really just disappointing to me and a clear sign that someone doesn’t get it.

“Stickiness” is the value you are creating that cannot be provided anywhere else and has nothing to do with whether your customer is “stuck” with you or not.

The decision that Flickr has made is to allow public access by competitors to their public API’s is a good one. I do disagree with Tom on one point, in that I think that the requirement that such competitors are required to provide a complete and accessible public API for them is a good one. I think thats a fair trade off and overall will set an example and a requirement to play fair and an expectation that when you take advantage of openness, you must be willing to be open yourself.

Oddly, its the same example Stallman has been trying to set for years …

The Labs Adds A Mac

Your looking at the first post to this web site completely written on a Mac.

Yep, thats right. A Mac.

Since the release of OS X I’ve wanted to make the leap to the Mac. The idea of a Unix based system with the useability of a Mac intrigued me to no end. I also have a couple of friends that have used Macs from what seems like day one, and have always told me that I was missing out on something cool. I just haven’t been able to justify getting one in my own head.

I think the clincher for me that a Mac was in my future was when Jonna started bringing one home for her testing work and I was watching her use it. It just looked so cool! Its been on my mind for a couple of weeks now, so yesterday we decided to take a road trip out to the Apple store and “just look” at the Intel based MacBooks to see whether it might be something I want to commit to as my next machine.

Well, I wound up walking out with one with the voice of an Apple customer from the store ringing through my head, echoing softly, “Once you make the move, you will never go back …”.

I got the machine home and booted it up. Within literally 15 minutes or so, I was hooked to our wireless network here at the Labs. Another 25 minutes or so and all of the software updates were downloaded. A few trips to grab the software I use most, like FireFox, the Flickr uploader, etc. and I already felt like I was home.

Of course, being a developer at heart, there are a few things I just had to do as soon as I got the base software like my favorite browser installed. I had to dive to the Terminal window and see what was out there.

Perl? - Check.
Python? - Check.
Ruby? - Check.
Java? - Check
Subversion? - Nope, but a few clicks and it was installed.
Screen Capture Tool? Kind of - only supports TIFFS. I need JPG for Flickr. A quick Google search got me to Snap N Drag, a free screen capture utility that supports JPG files.
iTunes - Check.
Office Suite? Nope - not there. Have to install OpenOffice, which requires X11. I’ll do that tomorrow.

Here’s the great thing about the whole experience. Every scripting language I use for every day work is on the machine from the moment I opened the box, even my old familiar friend, the bash shell. The important software I use day to day is at least available for me to install.

My email, calendar and news reader? I use Google, for all of that, so there was no setup or importing of data required. I just log in and feel at home.

The loose ends I have to tie off at this point is moving all of my iTunes stuff to the new machine. I’ve found a few articles on this around the NET, but the volume of data I have to transfer is becoming prohibitive. For some reason, rsync just stops part way through the sync — but I’ll get this worked out.

I’m extremely impressed with the machine so far. It has all of the utility of Unix and all the beauty of a Mac. I’m really not sure what else anyone could ask for.

Customer Self Service

As a customer, I like to be in control.

Our family goes out to eat at least once a week (on weekends, mostly). Many times once we are seated we spend quite a bit of time waiting for our initial drink order to be taken, then for our actual order to be taken, then for the check to be presented, and finally for our payment to be taken by our server. I know, pretty normal scenario — what is there to complain about?

Well, I’m not complaining really, just thinking. How could you enable customers to order for themselves and pay when they are ready to leave? Would putting customers more in control of the things they have to participate in anyway increase their satisfaction with the service?

I’d love to see a restaurant in which you are handed a wireless device with a card swiper as you are seated (or it could even already be at the table). The device can be used to select your drinks, appetizer, and meals which is routed to the serving staff (haven’t figured out the specifics of this one yet) who can then fill the order and bring it to you. Once you have finished your meal, the device can present the charges for you, allow you to swipe your debit and / or credit card and pay for the meal. Absolutely no waiting involved except to have the actual things you order delivered to your table.

Tom the Architect has told me that they have something like this in Vegas. I can’t wait for it to get to the mainstream. As a customer, I like the idea of being able to take care of the things I’m able to take care of without waiting on someone else to act first. I like to be in control — and I’m guessing that most people feel that way. I’m more satisfied when I feel like I’m more in control of the situation.

I think the one area that would have to be worked out is the security of the system. As we were sitting in a restaurant one day, I decided that I would enlighten my wife, Jonna, about these ideas. The first thing she hit me with was the opportunity for credit card fraud (she has the innate ability to point out flaws in the utopian ideas I come up with).

She brought the same thing up a couple of weeks ago when I was complaining about having to wait on someone to come over to the Jewel self-service checkout aisle to press a button to allow us to buy a six pack of beer. I started railing on as to why friction had to be added to the transaction, since the bank that we have the credit/debit card knows how old I am and can verify my age electronically. Jonna brought up that it would be quite easy for kids to take their parents credit cards and just go buy alcohol if age verification was done from the credit card (see, I told you she was good — I didn’t think of that).

Ok, thats a problem. What if in these situations you could get the benefits of “frictionless shopping” if you transacted with your debit card only and kept the PIN away from your kids? Then I could have my “lack of friction” and we could ensure that the kids weren’t off buying Tequila on my identity.

These are just a few things that I think about every now and again when I have to wait around for things that I know technology can solve. I love the idea that we are getting to the point where we can automate the friction out of a lot of the transactions we perform in daily life. Now and again, I’m disappointed that we haven’t removed all of the friction that we could out of the process.

As a customer, I just really like being in control.

Podcasts Moved To podcast.bieberlabs.com

I’ve been thinking for a while about moving the podcasts out of the main site in order to continue doing them but see what is going on from a traffic perspective. One of the things I wanted to do was change the feeds to use FeedBurner for the podcasts alone as I did with the main site.

On November 14, Tony Steidler-Dennison of The Roadhouse put up a show in which he was talking about how his feeds were split and asked all of his subscribers to resubscribe to the new feed so that he could get numbers to use in his talks to get permission from labels to broadcast music. As I listened to this, I was a little concerned at inconviencing the small amount of people who might have actually took the time to subscribe and listen to the drivel I’ve been putting out as I learn how to do this stuff. I didn’t want to have to make them resubscribe to a new feed, so I rethought my original plan to move the feeds to a different site.

Then I said to myself, “Self, there must be a way to redirect the feeds to a new feedburner feed from iTunes, and if there is, there must be a way to redirect them to a new site as well”. So I started playing around.

Luckily, before I submitted to iTunes, I thought ahead enough to use Apache URL rewriting to rewrite the URL http://www.bieberlabs.com/wordpress/podcasts to my Wordpress RSS feed in order to provide a level of indirection to the podcast RSS feed. This is the URL that I then used to submit the podcast to iTunes. Since I had this level of indirection, once I moved all of the content and set up a FeedBurner feed, all I had to do was add this little section to my .htaccess file to redirect to the new feed:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wordpress/
RewriteRule ^(podcasts)/?$ http://feeds.feedburner.com/bieberlabspodcast? [R]
</IfModule>

This little block of instructions tells the Apache server to redirect any requests to http://www.bieberlabs.com/wordpress/podcasts over to the new FeedBurner feed, making the transition to the new site completely invisible (at least it is to me so far).

So, all of the podcasts are now finally moved to http://podcast.bieberlabs.com. This site will be used to only support my podcasts, which will be refocused on instrumental guitar music like the stuff that I played on the 7th show. I have always had a real passion for this type of music and I have to say, Rory’s music completely inspired me to refocus.

So, in addition to the new site, I’m putting a call out to instrumental rock guitarists. If you create this type of music, please send it to me (bieber.r_at_gmail.com) so that I can start creating shows highlighting this beautiful type of music. The great thing about podcasting is to be able to create shows around niches and aside from Satriani, you rarely hear this type of music on the radio. I’d like to be the place in which people come to find this kind of music and to be able to give the artists a place to have their music played. The frequency of the show, at least initially, will be dependant on the amount of music in this genre that I can find, but hopefully as people see this and submit their work, it will be more frequent.

I hope the new shows are to someones liking. I also hope this explanation of how I moved the content without interupting iTunes service is helpful to someone starting out. Until Apple gives us a way to modify a feed URL in the iTunes interface, this is most likely the way that moving content like this needs to be handled and I feel really good in figuring out how to get around this gap in the interface.

To those who are subscribed or listen to these shows periodically, thanks for being patient as I stumble through the learning process. This has been a lot of fun for me so far and I hope to get a lot better and have a lot more fun in the future.

Software based IP PBX System - Sphere Communications

Yesterday I saw a presentation by Sphere Communications showing their product Sphericall, a service oriented PBX system.

The ideas in this software were really cool. The product is a software based IP PBX system which includes a SOAP based interface into the system, allowing you to completely integrate your VoIP network with your business applications.

The ideas presented in the presentation were pretty interesting. The product integrates phone, IM, and presence capabilities into its main desktop product, and also allows integration via web services to your business applications, allowing you to integrate your phone system into any application via a standards based interface.

Imagine being able to pop up customer information as soon as they dial in and being able to greet them by name and have their full history available to you right away via your CRM application. Imagine being able to put together conference calls by dragging and dropping people into your conference bridge when they call your office number. Now, image having IM like presence capabilities built into your phone system, so that you know whether someone is on the phone without having to call and be dumped into phone mail. These scenarios and many others were some of the things that Todd talked about during this presentation.

I thought the product looked extremely cool and shows a vision of corporate communication systems that is very compelling and exciting. The company has a whitepaper available on their web site (registration required).

Hardware Upgrade At the Labs

About two years ago I bought a Compaq Presario 3000 laptop computer as my primary machine. It started overheating whenever I would try to check things out of a source repository or build software on it. I had it dual booting Windows XP and SuSE Linux 9.1. The overheating would cause it to just plain shutdown on Linux, or completely freeze under Windows XP. It was impossible to get anything of any substance done on the machine past email and web browsing, but I stuck it out because I didn’t want to spend more money on a new machine — and I didn’t want to be without a machine for 4-6 weeks while they sent it in for repairs.

At the time I bought it, it was brand new on the market and the poor customer reviews weren’t available. By the time I called support, the machine was on Compaq’s “classic” list.

Last month I got completely frustrated and decided to go out and find a laptop. I settled on the GATEWAY 7422GX Notebook Computer. It’s a 64-bit AMD chip with built in wireless, universal card reader, and DVD-RW drive. To be honest, I was actually too cheap to settle on this one and bought a cheaper model. However, that model I soon found had a known defect with the system restore, and they let me trade up for this model for the same price. You have to love Best Buy.

My first inclination was to again dual boot the machine running Linux and Windows XP. I need XP because my Digitech GNX4 software does not run on the Linux environment. However, once I got Linux on the machine, I found that the wireless card wasn’t supported on the distribution of Linux that I was installing (or if it was, I couldn’t figure out how to get it running after hours and hours).

Rather than spending my time wrestling with the machine and operating system for hours on end, and realizing that I actually wanted both Windows and Linux without having to reboot every time I wanted to change operating systems, I grabbed VMWARE WORKSTATION 4.X for Windows NT/2000/XP and installed it.

I decided that this time around, I was going to try out Fedora Core 3 as my Linux operating system. Having VMWare at my disposal was great, as I could muck about with the configuration as much as I needed to without hosing the machine. Once I found the documentation on getting the VMWare tools installed under Fedora, the machine has worked great.

In addition to being able to run multiple Linux distributions at my whim, the virtual machine is also able to piggy back on the hardware drivers for the Windows operating system, giving me access to my wireless network from my Linux installation. For each virtual machine installation, I now have the ability to snapshot the environment before making any major changes, guaranteeing that I can get back to a working installation.

This is truly the best of both worlds. If you want a truly safe way to run Linux on newer hardware and have any questions as to whether it will run or not, I highly recommend VMWare as a platform to integrate Linux into your daily work. I haven’t been happier.
