Leaks or Marketing?

As the latest round of leaks make their way through the copy-me-too sphere... are they really leaks or are they a marketing ploy on behalf of the marketing teams and/or publisher?

The manufacturer's love this stuff because they get all sorts of buzz, mindshare, and with any luck they get to sample the public to determine just how successful the launch might be.

The publisher's love this stuff because is increases their readership. Right or wrong the public enjoys a little drama and a new secret project is the way to do that.

When I think about a a leak, however, I'm always thinking that it's a "deep throat".... when it's not really a person at all. In some cases it's just some detective work akin to dumpster diving. Some folks are reverse engineering the manufacturing breadcrumbs... but for all that effort...

The one thing that always seems to be missing is the names of the people making the discovery or the leaker. So I'm not certain that there is on…

I was once a RockStar programmer

I think I *was once* a rockstar programmer. I was (a) more productive than my peers (b) understood and solved complex problems (c) intimate knowledge of every part of the stack from the CPU, CPU cache, memory and disk systems, all manner of device drivers, complete knowledge of the OSI stack, and the internals of DOS, OS/2, Windows and AIX; as well as realtime systems. Later when I started developing transaction systems for business I had managers who treated me like a rockstar and they allowed me to behave like one. (releasing my inner a-hole).

I'm reformed now. Many of my peers type faster than me and there are many more of them. Most complex problems are no longer complex thanks to a lot of open source and the internet. Since I no longer work on projects that have that sort of demand I have allowed a lot of that information to flush my cache. It's nice to refresh from time to time but not required to do my job.

And finally, my managers are more sensible now. The industry as…

Apple Radio

I like my Pandora service. I've tried the others but either they were too expensive or constantly trying to sell me something. Today I'm trying Apple Radio. The UI experience on my iPhone and desktop are ok. I had to make a point of disabling my iTunes from downloading media on the cellular data network. However, not everything is rainbows and unicorns.

I want to know if Apple under estimates the ability of the average iTunes user to locate the BUY button or are they hoping for accidental BUY clicks. The BUY button appear in the play window, the mini-player window, and in the station history. Some of the buttons are camouflaged (probably unintentionally) and others are practically on top of other controls.

Given that the app-store return policy is non-existent I'm not sure what trouble this will bring.

Gaming the system

With 20% of the yelp reviews being forgeries what is the point of trying to develop an online brand for yourself? It would seem that most online users are aware of these numbers and are naturally skeptical of any sort of online information or propaganda.

FSMDD (FDD) - Finite State Machine Driven Development

There isn't a NEW method, model or process for developing software that does not seem to have a 'DD' as a suffix. eg; MDD, TDD, DDD, BDD... I'm not certain if this suffix is supposed to provide instance credibility or if it's just a vogue thing.

So I hereby declare that FSMDD or FDD, for short, has arrived.

FDD is the implementation of a finite state machine that whose nodes contain state specific information that is used to operate/compute against an event context. Individual FSMs can operate like subroutines with fanOut/fanIn, call, or fork -like process control to/from other FSMs.

What makes this particularly strong is that (a) by reducing the number of conditionals in the compute portion of a state node testing is simplified (b) by using the state machine representation, as data, it is trivial to graph in order to provide self documentation (c) once the inventory of compute-operations is complete the assembly of the individual FSMs is fairly routine.

As a side …

Do you really want to improve your code quality? Try this!

I have been tooling around with a code generator. Some piece of code generates some other, intermediate, piece of code; which is then compiled. However, along with the intermediate code I also generate state diagrams using graphviz. The outcome produced some wild results. (a) I caught more of my own bugs before letting them escape into test. (b) as part of the documentation it allowed the product owner, QA, audit etc... to validate the requirements with the code. This is MUCH better than writing your own flowcharts or even TDD, BDD, MDD, DDD, etc...

The second observation. While the code was being generated from artifacts in a database; with the intent that different code fragments that were stored in the DB would be reused as-is; It became necessary that the generated code (a)implement immutable variable names, (b)class attribute names, (c)function names and (d)class member function names. Which if you have not guessed it flies in the face of everything we know but let me explain.

1) G…

Who is writing your testcases?

Cucumber is just a way to wrap RSpec tests with a non-technical syntax. Any supposed benefits of it go to waste because code is only interesting to those who are working in it. Quit writing cukes unless you can honestly say that there is someone reading them who would not understand pure Ruby. --Kevin LiddleInstead of trying to find ways to flatten the organization, share blame through consensus, programmer commoditization, maximize profits at the very edge of the bell curve where it's just not practical...

If there is one thing that the Agile Manifesto does but does not say... smart people do smart things, most of the time, and get stuff done.

The Ubuntu edge

Even if canonical manages to deliver on the promise of the Ubuntu edge I think they are going to face an uphill battle all the way. Now that I have downloaded the latest iPhone, version seven, I realize the importance of incremental software user interface changes. 
The killer interface would've been accomplished had Apple been able to implement both the legacy and the next-generation interface simultaneously. The classic interface would've been helpful as some of the slower to adopt users would not panic or be forced to use more traditional pushbutton phones. 
The next few weeks will be very interesting for Apple's future.

GoLang - leave leave the cruft at the door

It's hard to take an programmer and would-be technical author seriously who lists MS Office tools on his resume. (now I need to go back and check my resume) But what is really annoying is that one author wants the go team to add Generics and the other is looking for some Object-Oriented features. I'm not an expert on the GoLang mission goals, however, from my vantage neither G or OO are particularly interesting... and if I needed them I'd go back to writing in Java.

I'd prefer that the GoLang team focus on some more pragmatic ideas. I find myself using interface{} and reflection more than I want. I'm not certain if that's because I'm trying to circumvent some language feature or if this is the natural way to solve my class of problems; in either case I'd prefer that the GoLang team make the corrections but it's not important as I like it.

Another statement comes to mind. Something like: GoLang was not designed to be terse but correct. (or something li…

Focus on the problem not the tools

Reviewing some code that it only about 5 years old I was sad to see I broke some common sense best practices. The code was a mix of http server, serial port i/o, database client, and device driver. Even though this was the 2nd generation of refactored code I still see a solid coupling of i/o and workflow or behavior.

The reason the code is so hodge podge is because the standard C program does not abstract enough of the environment away in tools or libs unless you're willing to depend on mountains of dependencies. And 4 years ago it was not a simple task to link serial i/o with an http server in a compiled project (scripting was not an option)

If I had to do it all over again... GoLang.

Apple's customer service continues to slip

I just left a retail store after making an appointment week in advance. My expectation was That an Apple technician would replace the damaged or defective battery on my laptop. Whether it cost me anything to replace was not point. In fact I was there to pay the  $129 replacement fee.
The issue is that Apple wanted to take my computer into custody in order to effect repairs. That was simply not an option this time. As Jordan explained to me this is pretty straightforward replacement however he didn't have any technicians in the back and although he was a technician himself he was not authorized to perform any technical repairs that day.
So what is the point of making an appointment with an Apple genius if they can't make the repairs when you're at the store. It's the sort of experience that makes owning multiple computers at a much cheaper price the better alternative. I can now envision owning multiple Google Chrome books. The work that I'm pursuing currently could b…

GoLang when to use a struct and when to use a pointer?

The GoLang language experts like using pointers and I have to agree that it's better to pass around pointers than it is full data structures. Of course this upsets the garbage collector and it's not very functional when you start talking about immutable data... On the other hand there are a number of one-liners that make programming fun.

Here is a pointer version:
query := new(Query)query.I = 1query.Select()
Here is a struct version:
Query{I:1}.Select()In this case the Query structure is meant to hold a collection of named parameters for a well known DB query and it is very short lived. In the struct version the select() can be called as a one liner making the code very simple and short.

Message queues are fun but they won't save the world

There are many more anti-patterns for using message queues then there are idioms. Message queues are useful for marshaling events around the system of services. However things go very wrong when the object being ferried around her system are larger than some marginal set. The limit for a message to item should probably being no larger than a single TCP packet somewhere around 1K. this is just one case there are many more.

Purpose built IDE's.

I really like the brackets editor. However it seems to be a special-purpose IDE. It supports JavaScript and other server-side client-side editing tasks and files. If your ecosystem is exclusively Implemented in JavaScript both client-side and server-side than brackets would appear to be an ideal IDE. 
However in the real world this is not practical. Most projects are poly-lingual meaning that they include languages and features from multiple sources. For example building web application using go requires both syntax analysis and Lint plus HTML JavaScript CSS. Additionally you need to be able to edit various dot files access files configuration files all of which would be nice if there were some pics highlighting for.
On the other hand generic editors like that brains and clips and NetBeans seem to miss the mark when it comes to building apps. They have certain customizations that allow them to build apps for a select set of projects Or project types. These IDEs will always be a work in …

I finally found a practical use for domain specific languages.

I finally found a use case that makes sense for DSL. In truth it's not really a DSL but a T-DSL. The T stands for transformative. A perfect example of a Transformative-DSL would be something like spec. Where TSON and XML are simple containers for the DSL.
As an example of a DSL anti-pattern; consider the puppet DSL. The DSL itself is constructed in Ruby and the configuration that drives the actions are also constructed in Ruby. This method of configuration tightly binds the configuration itself to the underlying DSL implementation. The configuration is no longer transformative across like patterns. It depends on Ruby itself being cross-platform. Thus making Ruby dependency the overall architecture.
