Choosing the right programming language

Choosing the right programming language for your next killer application could be harder than you think as there a number of dynamics out there that represent the facts and bike shedding opinions that represent the fiction.

I recently read two articles that put things into perspective. The first was TCL for network programming and the second was Boeing's 777 is 99.9% Ada.

The thesis for the TCL article comes down to this: TCL is not going to be overrun by a 100mb network. And the thesis for Ada: getting all of the developers "working together" (if I remember my Ada it has a strong producer/consumer contract) and built-in testing.

There are a lot of modern and legacy programming languages to choose from. No one language (or framework) is truly better than the other. They all have their warts.

  • package management
  • version skew
  • tabs vs spaces
  • functional vs procedural vs object-oriented
  • mindshare
  • cross platform
  • interpreted vs compiled
  • static vs dynamic linked libs
  • type system
  • dynamic declaration
  • testing
  • compile time
  • compile-time vs runtime dependencies
  • installation magic
  • libraries (CPAN is the aging Rock Star but still rocks hard)
I'm certain there are other qualities. This was not meant to be exhaustive.

My current go-to language is Google's Go and there are a number of reasons:
  • static compiled
  • support for Linux, BSD, Darwin/OSX, Windows along with capable cross-compiling
  • good standard library
  • testing framework
  • fast compiler/tool chain
  • no need for autotools
  • strong CI tools like drone and travis
  • I really like being able to transcode messages using structure tags
  • concurrency and channels are cool but not necessarily awesome
I've complained about Python3 and Perl6, in the past, but I still like them both; however; I think the next app/tool should be in TCL. (active state could not afford to continue it's development if there was no market for it) I would also add that TCL was the language that we used to develop the command and control code for the SnapGear brand of firewall/routers.

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: http://www.eeti.com.tw/drivers_Linux.html (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).

TL;DR;

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…
