WSL and samba mapped drives in Fall Creator’s Update

October 18, 2017

It looks like the DrvFS driver requests execute permissions on all requests to remote drives. With recent versions of samba, this can result in unexpected Permission Denied messages when trying to open any file without the executable bit set.

As a work-around you can update your smb.conf and turn off execute permission checking:

acl allow execute always = yes

Using tds_fdw with postgresql in windows

April 6, 2017

Install Postgresql using the bigsql distro

Follow the instructions at the install page.

Install tds_fdw1-pg96

C:\bigsql>pgc install tds_fdw1-pg96

Setup a database and user in SQL Server and a test table

CREATE TABLE test1 (id integer, name varchar(255));
INSERT INTO test1(id, name) VALUES (1, 'hello, world'), (2, 'I am a banana');

Set up the extension in postgres

CREATE EXTENSION tds_fdw;
CREATE SERVER 
    tds_test_server 
    FOREIGN DATA WRAPPER tds_fdw 
    OPTIONS 
        (
         servername 'localhost', database 'test', 
         port '1433', msg_handler 'notice', character_set 'UTF-8',  tds_version '7.1'
        );

CREATE USER MAPPING FOR 
    testdev 
SERVER 
    tds_test_server OPTIONS (username 'username', password 'password');

Note that if you do not specify character_set, you will get an unable to connect error and you will bang your head against the wall for hours

Create the foreign table

CREATE FOREIGN TABLE test1 (id integer, name varchar(255)) SERVER tds_test_server OPTIONS (table 'dbo.test1');

Query your new table

SELECT * FROM test1;

Enjoy!

Everyone Hates PowerPoint, so Why Do We Use it?

September 23, 2016
  • PowerPoint is dumb
  • Slides are the worst way to engage an audience
    • But they are low effort
  • People often think in bullet points and slides are conducive towards that
  • Slide decks are pre-organized notes that can be given out after the fact
    • So you don’t have to pay attention
  • Building a slide deck signals, “I AM PREPARED THIS IS IMPORTANT I AM IMPORTANT”
  • Working on a slide deck is a dodge to get out of doing real work
  • Slides present the illusion of consensus

Monolith First?

June 3, 2015

Martin Fowler has written an article about Microservice design, which hits home with me:

MonolithFirst

This pattern has led many of my colleagues to argue that you shouldn’t start a new project with microservices, even if you’re sure your application will be big enough to make it worthwhile. .

 

I am becoming more and more convinced that proper software architecture is reactionary, and being disciplined enough to find ways to refactor large projects in situ, rather than trying to scrap and rewrite (as every engineer I know is wont to do).

My Daily Work Log Template

May 22, 2015

I keep a daily work log adapted from a template I got years ago at a job.

It’s useful for me, to be able to look back at what I was working on as well as a convenient place to keep notes. It can be useful to keep yourself honest, as well as a place to track interruptions if you’re into that.

Sublime Text and Cygwin

May 21, 2015

Quickie shell script to use sublime as your editor in cygwin

Create ~/bin/subl

#!/bin/bash
/cygdrive/c/Program\ Files/Sublime\ Text\ 3/subl.exe cygpath -wa "$*"

You may want to add the -w flag if you want to use it as your commit message editor for git/svn/hg/etc, which will cause it to wait until you save and close the file in Sublime Text before returning control.

VCVars for Cygwin and Visual Studio 2013

May 20, 2015

I’m a unixy guy working on a .NET codebase, and while I can’t get away from Visual Studio completely, I do like to be able to run msbuild from a cygwin shell. Converting the MS supplied VCVARS.BAT file to something bash could understand was a bit of a PITA and I don’t want to have to do it again, so for your enjoyment is my version of vcvars.sh: vcvars.

Don’t blame me if it doesn’t work, but it might get you started.

14 Principles of a Software Architect in an Agile Environment

May 19, 2015
  1. Facilitate rather than dictate architecture
  2. Negotiate for the reduction of technical debt
  3. Lead by example
  4. Embrace emergent design
  5. Refactor relentlessly, harvesting application idiomatic patterns
  6. Design with the expectation of change
  7. Extract Embedded Frameworks
  8. Make design choices at the last responsible moment
  9. Do not try to predict the future
  10. Rely on tightly coupled team discussions to make and socialize design decisions
  11. Choose simple solutions that can be replaced later once more complicated design is required and when the limitations are more well known
  12. Do not enable those would use architectural considerations as a pretext to force waterfall processes
  13. Rely on team members to make rational, adult decisions regarding code, and use refactoring as a mentoring opportunity
  14. Do the minimum amount of upfront design necessary to clear easily visible pitfalls, but expect to have to pivot at any moment.
