I've been soldiering on for a couple of years on a T-Mobile Wing.  That old phone did some pretty great things for my personal organization, but I always seemed to struggle with connection issues.

Last weekend, I finally bit the bullet and picked up a new HTC HD2.  Make no mistake, this is a spectacular piece of hardware, but sadly, I still find myself chasing connection issues.  I'll share some thoughts on the rest of the phone later if I end up keeping it, but right now, I want to detail my signal strength problems.  I'll continue to update this post as the fun and games ensues, so if I (or T-Mobile) manage to fix the problem, this post will show the resolution, and if not, you'll be able to see why I left.  All of the observations here, unless otherwise indicated, occured in exactly the same spot in Columbus, Ohio, near the OSU campus (ie, not while moving around).

Sunday, 3/28

• Bought the phone, took it home, charged it, and powered on.  No data connection.  It turns out that the upgrade to 3G takes a while to provision.

Monday, 3/29

• Signal bounces around all day.  Full-strength Edge, then nothing, then 3G, then nothing, then no connection at all.  This goes on most of the day, with almost all day spent on Edge only (no 3G).
• In the evening, I got a good 3G signal, and the phone worked great.

Tuesday, 3/30

• Slightly better luck with 3G, but not by much.
• I talked to a couple people who said they tried to call me several times -- the phone never rang, and didn't show any missed calls.

Wednesday, 3/31

• Noticed the same problems.  Signal really bouncing in the morning.
• Called T-Mobile customer care at around 11:45.  Rep advised me to power off and back on a couple minutes later, and asked if I could call from another line (I can't).
• Immediately upon powering up, here's what I saw:
• 11:57 - 3G w/ 2 bars.
• 11:58 - Edge w/ 3 bars.
• 12:00 - no service (I was trying to dial voice mail).
• 12:00 - Edge w/ 4 bars (after I stopped trying to dial VM).
• 12:01 - no service (as soon as I dialed VM).
• 12:20 - 3G w/ 3 bars.
• 12:20 - Call to VM fails.
• 12:22 - 3G w/ 2 bars.
• 12:22 - Call to VM fails.
• 12:24 - Call to VM fails.  "Phone operation failed" message.  Immediately saw Edge w/ 4 bars, then no signal.
• 12:26 - Finally completed a call to VM.
• 12:27 - no service.
• 12:28 - no service - unable to place call.
• 12:30 - placed call - it worked!
• 12:39 - Edge w/ 4 bars.  As a side-effect of the connection-hunting, my battery is down to 57% - I noticed this sort of decreased battery life when my Wing was connection-hunting, too.  Done troubleshooting for now - my lunch is over.

Douglas Adams, muse to software developers everywhere, had this to say about bugs:

"Just as a slow series of clicks when speeded up will lose the definition of each individual click and gradually take on the quality of a sustained and rising tone, so a series of individual impressions here took on the quality of a sustained emotion[.]"

Ok, yeah - the quote is really from "Life, the Universe, and Everything", and he wasn't talking about bugs, but he could have been.

If you look at bugs one at a time, you can miss some important "big picture" stuff.  It's possible to spot product design issues, usability issues, architecture issues, and more by looking at patterns across multiple bugs.  Instead of just taking the bug at face value, consider whether there are other factors that caused this bug (and others like it) to show up.  Unless you're writing mission support modules for NASA, it doesn't make sense to do a full five-why's breakdown on each bug, but keep your eyes open for signs like this:

• You find yourself going back to the same area of code over and over.
• User complaints cluster around a few screens (or functions) in your application.
• You recognize a similar pattern in source code that keeps popping up.

When you see patterns like this, you can certainly keep on fixing the bugs one at a time, but it's pretty hard to make progress this way.  Instead, consider a larger bug fix, or even an actual feature (there's really no difference, IMO) that cuts across individual bugs and fixes the foundational problem that's spawning them.

• Maybe you need to redesign a screen.  If users are having a hard time figuring out part of your application, you're not going to be able to fix your users.  Bite the bullet and figure out what you need to change in your application so that it makes sense.
• Refactor ugly code.  This should be a no-brainer.  Spaghetti code can hide a multitude of sins, and the bugs are just going to keep coming until you deal with the problem.
• Address architectural issues.  Sometimes, your problems run really deep, and big changes are needed to fix them.  This can be a tough sell, but if you can show a pattern of costly bug fixes over time, all of which share an architectural root cause, you've got the ammunition to push for a fix that will make them go away.

If you eliminate the sources of these clustered bugs, you not only get rid of the current bugs, you wipe out a whole swarm of future bugs before they've had a chance to show their ugly little faces.  Don't believe for a second that you can do this one bug at a time.

I'll just grab a cup of coffee, ok?

Here's an example of a good idea gone wrong.  I saw a link for a web site that exists solely to advance openness in government.  How cool is that?

I clicked around for a bit, eventually reaching a place where I was supposed to be able to submit an idea for government, where it would (presumably) be viewed and discussed among my peers.  When I clicked the button to enter my idea, I was prompted to log in with OpenID (again, very cool).  I logged in and clicked the button again, and was rewarded with the following barfage:

Close, guys. Very close!

Please don't do this to your customers, okay?

Microsoft's S. Somasegar ("Soma"), who heads the Developer Division, posted on his blog yesterday about "Key Software Development Trends".

I was pleased to see him include "Proliferation of Devices" among the top trends in development, but there was obviously an acute case of tunnel vision at work here, because Soma completely neglected all the non-Microsoft devices that people seem to insist on using.  I know, I know -- you can't have a Microsoft VP publicly acknowledge Apple on a corporate blog; that's just craziness, but the rest of us sure can.

As I wrote in my last post, the proliferation of devices -- especially across platforms -- has the potential to impact me in a pretty fundamental way.  It wasn't long ago that I could develop a web application and have a reasonable expectation that most clients could use it, regardless of their client architecture.  Differences existed among browsers, to be sure, but there were relatively few "can't get there from here" moments.

There's no question that what Microsoft really wants is for us to develop software with Microsoft tools on a PC running Windows, and then to distribute this software to consumers who are also running on a Microsoft-powered device of some sort.  When Microsoft held near-monopoly positions on every platform where computing reasonably occurred, this was tenable.  Today, though, it's just not reasonable.  Customers are computing on a dizzying array of devices, and not all of them are powered by Microsoft.

What's needed today from Microsoft is real development leadership.  Give us a runtime that works everywhere, and Visual Studio becomes an absolute no-brainer choice for development.  While this might seem like a daunting task, a good part of this work is already being done.  Miguel de Icaza's efforts with Mono have paid incredible dividends to-date.  Today, because of Mono, you can:

• Run C# code on Linux.
• Develop C# in an IDE on Windows, Linux and Mac.
• Write .Net code that deploys to J2EE application servers as Java bytecode.
• Run SilverLight on Linux-based machines.
• Write C# applications that run on the iPhone.
• Write games for Windows, Mac, and iPhone.
• Write C# applications that run on Android phones (okay - this one isn't ready yet, but it's coming!)

Microsoft, please jump on this bandwagon!  Visual Studio is so clearly superior to other development environments that its only current threat is developers hemorrhaging to develop for other platforms.  Making Visual Studio a true cross-platform tool could make that argument a non-starter.

Similarly, SilverLight could very easily overtake Flash as the most widely-available rich UI runtime, but support for more mobile platforms will surely help this cause.  In a recent blog post, Miguel talks about a library for the iPhone that helps define UI's more declaratively -- a trait SilverLight already handles well.

To envision the kind of difference this could make, imagine launching Windows Mobile 7 with a few thousand iPhone apps ready to run on it.  This makes WinMo7 a much easier switch for consumers, and it could be a reality if we were already developing iPhone apps in C#.  Aren't the folks in Redmond sick of seeing every company from Dominos to Nationwide Insurance telling us to download their iPhone app?  Why not level the playing field and let these companies publish an app that works on any phone?

It's within reach.

The introduction of Apple's iPad got a lot of people talking about "apps" again. There's no denying the oppressive popularity of apps today; everybody's got an app store and everybody's playing catch-up with Apple. Apps are the new hotness.

Yesterday, Stephen Forte (Is the iPhone (and Android) the harbinger of death for web pages?) observed that apps kick the crap out of web pages when you're on a mobile device, which is why we're seeing an app revolution similar to the one that launched HTML (and the web) to prominence a decade ago.

The part he missed, though, is the negative impact of a fractured client landscape.

When you see a Fortune-500 company announce a new iPhone app, do you ever wonder what it expects its Blackberry customers to use?  How about Android?  Is the cost of the new app hotness a need to build four copies of every app?

On iPad day, I caught an interview on NPR's "Marketplace".  Josh Bernoff from forrester.com was talking about how the web is effectively shattering due to the different experiences on each of these platforms.  To me, this demonstrates that we're in the midst of a fundamental transformation.

The web (specifically, HTML) was the great equalizer. Any server could serve any client. This simple concept "made" the web.  We're now experiencing a shakeup to this universal access. The web is now accessible to more devices than ever, but the cutting edge is rich client development (apps), and this is hugely fractured. On the web, we have technologies like Flash and SilverLight, and on mobile devices, you can develop for iPhone, iPad, Android, BlackBerry, Palm Pre, Windows Mobile, and others.

Today's development tools give us no practical way to target all (or even most) of these client platforms "natively". This is not due to technical impossibility; it's a function of the power struggle that's occurring among these warring platforms. If Microsoft and Apple both wanted to see SilverLight run on an iPhone, I'm confident that it would have happened by now.

Instead, all the major players in mobile platforms want to own that whole space, and their proprietary UI's are required for this. If Apple, Windows Mobile, and Android all ran flash, for example, Apple's dominance in mobile devices would be severely compromised (after all, I can get the same "apps" on any device at that point, right?).  Apple doesn't want to see this, obviously -- it takes money directly out of their pockets.

The impact of the splintered web on developers is twofold.  First, and most obviously, every app must be coded from scratch to run on each platform a developer wishes to reach natively.  This is going to force a pretty uncomfortable reckoning with Product Managers, and it's probably going to mean that in many cases, only the top one or two  mobile platforms is served, leaving the rest of your customers to eat HTML table scraps.

The second impact on developers is a splintering of skill sets and tools.  If I want to port my .Net application to iPhone / iPad, I'm looking at a sizable intellectual and financial investment.  At a minimum, I need to buy an Apple computer, because you can't do Apple development on a Windows box (no monopoly there, right?).  Only then can I even begin to try to port or rewrite the app.  Tools like MonoTouch can help preserve my business libraries, but the UI transition won't be seamless.

In practical terms, the specialization needed to be good at developing for any of these platforms also means that any one developer can't be great at all of them, which implies that I need multiple developers to target multiple platforms.  This is starting to get expensive, now, isn't it?

In time, it's inevitable that the market will work this out.  One of the major platforms will win, relegating the others to the "Island of Misfit Technologies", or a number of them will agree to interoperate (via Flash, SilverLight, HTML 5, etc.).  In the mean time, though, businesses need to expect more expensive development if they want to reach all their users with native apps, and developers had better be prepared for more UI platform changes.

Do you miss the good old days of HTML already?

I consider myself something of an amateur photographer (yes, in case you're wondering, the photos are mine, be they ever so humble).  By amateur, I mean in part that I've learned enough to know where I stand against the ranks of really good photographers.  Among other things, I've come to understand that there's a lot to learn about photography before you can really hope to be good, but I also understand how people come to believe that they can be pro photographers just going out and snapping up the latest and greatest hardware.

The advent of digital cameras made photography accessible to a lot more people by making photography cheaper and easier by a pretty huge increment relative to film photography.  Once you've bought a camera, it now costs next to nothing to go out and shoot a couple hundred pictures in a day.  Since you can see your results immediately, you can also make changes to settings or composition in real time, which massively increases a new photographer's learning curve.  Bottom line: you can go from zero to decent in a very short time.

"And what," you might be asking, "does this have to do with software?"

One of the problems facing both photographers and software professionals, it turns out, is that it's pretty difficult for an uneducated consumer to tell the difference between "passable" and "really good".  This morning, I read a really interesting article by Scott Bourne: And You Call Yourself a Professional? In this article, Scott bemoans the fact that there are budget photography "pro's" who are dramatically undercutting really good photographers, producing mediocre results for the client and, in Scott's words, these proto-pro's are "dragging down an entire industry."

My first reaction, of course, was that this is one of the fundamental problems in our industry, too.  Good developers can spot bad developers a mile away, but customers and employers can't do this -- at least, not until they've become somewhat educated in the intricacies of software development.  This is one of the key ideas in another one of my recent posts:  Fixed bid isn’t nirvanna.

Is it really reasonable to expect that bad photographers or software developers are going to take themselves out of the market?  Not really.  In a well-functioning market, they're either going to improve or be driven out of the market, but they're certainly not going to experience a crisis of conscience and change their ways if customers are buying this stuff.

Instead, Scott's “We fix $500 wedding photography” idea is probably a lot more effective.  Customers need to understand how they're affected when they bite on low-ball services, but this is no small feat.  Think about it: if a customer is shopping for a deal, you're going to have a hard time explaining to them exactly what can go wrong by taking short cuts.

In photography, there's a misconception that since cameras can set exposure, aperture, and focus automatically, it's impossible to take a bad picture, but it's less clear how photography is elevated to art.  In software, a customer can see an application that appears to work, and have no idea that the system is riddled with technical debt that will make future maintenance and extension a nightmare.

I'd love to think that we could educate customers on a massive scale, and in the process, drive out bad development practices because no customer would ever tolerate them, but I'm coming to understand that sometimes, a customer just may not be experienced enough to understand why you're a better value than the "cheap" service.

How are you educating your customers?

It's CodeMash time again, and once again, I'm taking notes on my Adesso tablet, and uploading them with Evernote to a CodeMash public folder.  You can see all of my scribblings there as I sync and once again, I'll have some posts to follow based on what I'm seeing here.  There have already been some really fantastic sessions.
Update:  If you look at these notes, you'll immediately see two of the most troublesome issues (for me, at least) with the Adesso pad.  First, this pad uses a regular 8x11 pad of paper that's clipped onto the Adesso pad.  This part is actually pretty great, because I don't need special paper to record notes.  In fact, I almost ran out of paper during the conference.  With other pads, I might have been done at that point, but with the Adesso, I could (in a pinch), just flip the paper over and write on the back, or grab a flyer or whatever other standard paper might be laying around.

So what's the problem?  The pad can slip.  If there's any play in the pad on the Adesso tablet, the writing becomes pretty illegible - especially on the bottom of pages.  This is pretty apparent in a few spots in these notes.

The other big problem is that it's really easy to record right over the top of a page that's already got notes on it.  I've now gotten into the habit of advancing the "electronic" page when I flip the paper page - this bit me regularly for a while after I bought the tablet.  Last week, though, I fell victim to another variation on this theme -- the "page forward" and "page back" buttons are located on the left edge of the tablet, and being a lefty, I bumped them accidentally a couple times.  Without realizing it, then, I moved the "electronic" page back to one that I'd already recorded, and just kept right on taking notes, resulting in a double-exposed page or two.

A while back, a friend asked me some questions about getting started with Linux.  He wanted to know specifically whether he should pick up a copy of RedHat at the local retailer -- for  something on the order of $80.

I sent him back some notes about choosing a Linux install (distribution, or "distro"), and thought there might be some information here worth repeating.  Incidentally, you might find it worth trying a Linux Live CD (see below) even if you don't think you're a Linux person just to see how your hardware performs with another operating system - it can be eye-opening.

[callout title=Gnome or KDE?]When you start looking at distros, you'll immediately notice that most identify themselves as either a Gnome distro or a KDE distro.  Gnome and KDE started out as window managers, which meant that they were responsible for displaying, styling and managing the User Interface.  Over time, though, both have turned into extensive library installs, much like Microsoft's .Net framework.  If you install a lot of applications, you'll eventually end up with most of both frameworks installed, but only one of them (at a time) will actively run your UI.  In any event, you should try one of each and see if you give a hoot which one you use.  Read more about them here[/callout]

Don't install yet...

Before you install anything at all, you can play with a one or two versions of Linux to see what you like about each of them.  The easiest way for most people to do this is with a Live CD.  A Live CD (or DVD) is a bootable image of an operating system.  Just download the Live CD image (this will most likely be an ISO file), then burn the ISO file to a disc.  Leave the disc in your optical drive, reboot your computer, and make sure your computer is set to boot off the optical drive before it boots off your hard drive.

If you followed along to this point, you should see Linux booting off the disc you just created.  It'll start up, detect most of your attached devices, acquire a network address via DHCP, and you should end up with a working Linux desktop in just a few minutes without making any permanent changes at all to your machine.  When you're done, just eject the CD and reboot back into Windows.

... or don't install at all

The other way to evaluate Linux distros is with a Virtual Machine.  Both Virtual PC from Microsoft and VMWare (Player or Server) are free, and both can be incredibly valuable for testing, development, and so on.  Between the two, I'd pick VMWare -- it's fast, stable, and widely supported.  Plus, if you choose VMWare, you can download pre-built images from their Appliances site.  This can be even faster than using a Live CD once you've got VMWare installed.

The family tree

There are probably thousands of Linux distributions, or distros.  For some sense of scale, see this list or http://distrowatch.com/.  Despite these numbers, there are relatively few popular distros, and almost all of them have been formed by "forking" an existing distribution.  Thus, any distro you pick will come from a small number of "root" distros.  Take a quick look at this diagram to see what I'm talking about.

Although the specific lineage you pick shouldn't matter much, you'll usually see support articles refer to instructions for one or more of these roots, so it's helpful to know if you're running a Suse-based distro, or a Gentoo-based distro, and so on.

For what it's worth, the most popular general-purpose distro right now is probably Ubuntu, so if you're absolutely flummoxed right now about where to start, that would be a fine one to begin with.

But what about RedHat?

If you've made it as far as firing up one or two distros, you'll realize that you're not going to get much in the RedHat box that you don't get for free somewhere else - after all, that's the Linux way.  If you still see something on their feature list that you want to pay for, go ahead, though - at least you're an informed buyer now.  Of course, if you insist on buying a distro, Suse's enterprise distro is probably worth a look, too.

When a business wants a custom software deliverable, there's a basic decision to be made about how this software is sourced, or procured.  Like a buy-vs.-lease decision when you go to the car dealership, the business has to decide first if they can and/or will develop the software with internal resources, and if not, they need to solicit bids and pick a vendor to do the work.

For many years, the only way to obtain software development expertise from outside your company was to contract that expertise on an hourly basis.  In fact, this is still the bedrock upon which most "consulting" firms are based.  It's not sexy, but it pays the bills.  For customers, however, this can be an unrewarding experience because they still must provide most of the infrastructure of a software development shop, and in many cases, this just isn't feasible.

In order for consulting companies to meet this need, these firms began to sell "solutions."  In a broad sense, this is simply an arrangement to bundle all the work for a deliverable and charge per software deliverable, rather than per hour.

Solutions, then, are sold either on a fixed-bid basis, or on a time-and-materials (T&M) basis.  I'll forgo a full examination of either of these models here, because most people are familiar with these models.  Suffice it to say that "fixed-bid" remains by far the sexier option, because it promises predictable budget-to-expense performance for the business, and predictable forecast-to-revenue performance for the solution provider - both of which make management look great.

In actual practice, however, fixed-bid projects don't always turn out to be quite that tidy.  Requirements change, bids are supplemented by change controls, staff turns over, and any number of other minor catastrophes combine to make one or more parties in these transactions wish they'd done things very differently.

Over the last five years, then, any number of IT services companies have swung from 100% staff-aug work to take on a fair number of fixed-bid projects, and many have now started to swing back the other direction because of the pain they've experienced.  Fixed-bid is still a sexy sell, but it's now recognized as a tough delivery.

Customers have also had a chance to experience this pain.  When you fix the price of an IT deliverable, you're going to experience pain with each and every change you need to make.  In many cases, this will even include changes that you don't perceive to be changes at all, merely because requirements weren't spelled out clearly enough in the beginning.  Customers who aren't really good at analysis and requirements definition will very likely feel like they've be run through the wringer.

The bottom line for fixed-bid projects:  Customers who understand what they want, and can specify this in writing, will do fine in a fixed-bid scenario.  These customers are more likely to get the software they want, and their vendors are more likely to deliver this software with a minimum of drama.  If a customer doesn't understand what they want, fixed-bid probably isn't the right answer.  Instead, concentrate on prototyping or agile development to derive the right answer, but understand that the delivery schedule has to be subject to change as requirements become better understood.
