When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:
main {
max-width: 38rem;
padding: 2rem;
margin: auto;
}
# to generate your dhparam.pem file, run in the terminal | |
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048 |
[alias] | |
co = checkout | |
cob = checkout -b | |
coo = !git fetch && git checkout | |
br = branch | |
brd = branch -d | |
brD = branch -D | |
merged = branch --merged | |
st = status | |
aa = add -A . |
I recently wanted to rename a model and its postgres table in a Phoenix app. Renaming the table was simple and documented, but the table also had constraints, sequences, and indexes that needed to be updated in order for the Ecto model to be able to rely on default naming conventions. I couldn't find any examples of what this would look like but was eventually able to figure it out. For anyone else in the same situation, hopefully this example helps.
In the example below, I'm renaming the Permission
model to Membership
. This model belongs to a User
and an Account
, so it has foreign key constraints that need to be renamed.
defmodule MyApp.Repo.Migrations.RenamePermissionsToMemberships do
use Ecto.Migration
These rules are adopted from the AngularJS commit conventions.
-- This code is based on my other Gist "Simple linear regression in Javascript" (https://gist.github.com/patrickpissurno/ea0dc4039f075fbaf398619761bd9044) | |
-- There might be a more efficient way to do this in SQL | |
-- This function is resposible for computing the weights for the ax + b equation | |
CREATE OR REPLACE FUNCTION linear_regression(x_array decimal(15,2)[], y_array decimal(15,2)[]) RETURNS decimal(15,2)[] AS $$ | |
DECLARE | |

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'
Example: To get json record having _id equal 611
cat my.json | jq -c '.[] | select( ._id | contains(611))'
Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

Recently, many zone owners could not migrate away from Dyn since they were benefiting from non-standardised DNS-based failover and geographical loadbalancing features. What you see below is an attempt to get standards based but flexible equivalents of these currently proprietary features. Here is a zone:
