Pair Programming - shared experiences

I'm not a fan of continuous paired programming. There are a few cases where it makes sense. (i) new employees, (ii) rookie programmers (iii) certain rapid development cycles. However, sustained two users and one keyboard is simply not practical unless it's full contact MMA style.

There are a few other interesting offshoots. (a) Real-time file sharing (see subethaedit and coda) (b) splitting the coding into dev and test but coding in parallel and together. This can be even more fun when you add a third person who it structuring the module's API signature while the others fill in the blanks.

Pair programming is not meant to be arm chair programming or back seat programming.

  1. The traditional navigator/pilot model of pairing easily leads to detachment or keyboard bickering. The easiest way we found to make full-time pairing sustainable when I was at AirWave.com was to simply plug in another keyboard and mouse.

    Without resource contention, it's easier to fall into more productive pairing roles than navigator/pilot. The navigator/pilot model doesn't really work when pairing people who have years' difference of exposure to the project: eventually the senior person grabs the keyboard and starts working as an observed singleton.

    It's a lot harder to shut out your pair when they have equal control over the computer.

  2. Since you commented I started thinking about it some more. I think the only pair programming I would find comfortable or useful would be something similar to battleship and not etch-a-sketch.

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…
