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) Given a class User with a string attribute Name; we know a few things:

  • a class is nothing more than a container of attributes and methods
  • User is such a container with an implied semantic that it describes a user
  • and that there is a Name attribute in the User container
  • of course User.Name could have many semantic meanings
2) Given a class Printer with a string attribute Name; we know many of the same things.

Since the code I was working on was completely green field I was generating many new classes, structures and interfaces. I found myself copying code and attributes from gist to gist. As the code got more complex I found myself using lots of reflection (I'm not sure which came first; the complexity or the reflection) And one strange outcome was that I started ignoring the semantics of the class and just started copying like named attributes.

You might find yourself saying that this is all on me.  You'd be right too. But assuming that your language of choice implements a proper inheritance model or even proper OO structure -- all of that is a complicated waste of time. What happens when you are looking at... WindowsUser.Name and UnixUser.Name? Or Windows.User.Name and Unix.User.Name? Nowhere is this more obvious than Duck Typing. But even here you have the type and none of the semantics.

If you truly accept that the "class" does not really offer but the loosest semantics and that the strict semantics are on the actual attributes then you'll see the benefits of getting the names right across classes, structures and such.

Entry level cost for CoreOS+Tectonic

CoreOS and Tectonic start their pricing at 10 servers. Managed CoreOS starts at $1000 per month for those first 10 servers and Tectonic is $5000 for the same 10 servers. Annualized that is $85K or at least one employee depending on your market. As a single employee company I'd rather hire the employee. Specially since I only have 3 servers.

The pricing is biased toward the largest servers with the largest capacities; my dual core 32GB i5 IntelNuc can never be mistaken for a 96-CPU dual or quad core DELL

If CoreOS does not figure out a different barrier of entry they are going to follow the Borland path to obscurity.

UPDATE 2017-10-30: With gratitude the CoreOS team has provided updated information on their pricing, however, I stand by my conclusion that the effective cost is lower when you deploy monster machines. The cost per node of my 1 CPU Intel NUC is the same as a 96 CPU server when you get beyond 10 nodes. I'll also reiterate that while my pricing notes are not currently…

eGalax touch on default Ubuntu 14.04.2 LTS

I have not had success with the touch drivers as yet.  The touch works and evtest also seems to report events, however, I have noticed that the button click is not working and no matter what I do xinput refuses to configure the buttons correctly.  When I downgraded to ubuntu 10.04 LTS everything sort of worked... there must have been something in the kermel as 10.04 was in the 2.6 kernel and 4.04 is in the 3.x branch.

One thing ... all of the documentation pointed to the wrong website or one in Taiwanese. I was finally able to locate the drivers again: (it would have been nice if they provided the install instructions in text rather than PDF)
Please open the document "EETI_eGTouch_Programming_Guide" under the Guide directory, and follow the Guidline to install driver.

Prometheus vs Bosun

In conclusion... while Bosun(B) is still not the ideal monitoring system neither is Prometheus(P).


I am running Bosun in a Docker container hosted on CoreOS. Fleet service/unit files keep it running. However in once case I have experienced at least one severe crash as a result of a disk full condition. That it is implemented as part golang, java and python is an annoyance. The MIT license is about the only good thing.

I am trying to integrate Prometheus into my pipeline but losing steam fast. The Prometheus design seems to desire that you integrate your own cache inside your application and then allow the server to scrape the data, however, if the interval between scrapes is shorter than the longest transient session of your application then you need a gateway. A place to shuttle your data that will be a little more persistent.

(1) storing the data in my application might get me started more quickly
(2) getting the server to pull the data might be more secure
(3) using a push g…
