solar position calculator
function [angles,projection] = solarPosition(datetime,latitude,longitude,time_zone,rotation,dst)
%SOLARPOSITION Calculate solar position using most basic algorithm
% This is the most basic algorithm. It is documented in Seinfeld &
% Pandis, Duffie & Beckman and Wikipedia.
%
% [ANGLES,PROJECTION] = SOLARPOSITION(DATE,TIME,LATITUDE,LONGITUDE,TIME_ZONE)
% returns ZENITH & AZIMUTH for all DATE & TIME pairs at LATITUDE, LONGITUDE.
% ANGLES = [ZENITH,AZIMUTH] and PROJECTION = [PHI_X, PHI_Y]
% PHI_X is projection on x-z plane & PHI_Y is projection on y-z plane.
% DATETIME can be string, vector [YEAR, MONTH, DAY, HOURS, MINUTES, SECONDS],

Zero-knowledge databases

Zero knowledge databases

The idea

The idea is to provide a database as a service to end users in such a way that no one except the user herself can access the data, not even the hosting provider or the database administrator.

Advantages

  • A privacy- and/or security-conscious user will have more trust in such a setup.
  • The service provider cannot be coerced to release the data they were trusted with, and he cannot be held responsible for the content he is storing.

Upgrading PostgreSQL in Windows

Upgrading PostgreSQL in Windows

The official documentation for PostgreSQL provides a guide to upgrading using pg_upgrade. However, it can be a bit like a treasure hunt with hidden traps. This gist will walk you through a clear and robust method for upgrading PostgreSQL on Windows, using the upgrade from version 14 to 16 as an example.

1. Install the New Version of PostgreSQL

Before you embark on the upgrade journey, make sure you have the new version installed. This is because the pg_upgrade utility used during the upgrade process belongs to the newer version.

To get started, visit the official download page, download the installer, and run it. A word of caution: do not overwrite the old installation, as you'll need its binaries and data for the upgrade.

Make Ubuntu packages 90% faster by rebuilding them

Make Ubuntu packages 90% faster by rebuilding them

TL;DR

You can take the same source code package that Ubuntu uses to build jq, compile it again, and realize 90% better performance.

Setting

I use jq for processing GeoJSON files and other open data offered in JSON format. Today I am working with a 500MB GeoJSON file that contains the Alameda County Assessor's parcel map. I want to run a query that prints the city for every parcel worth more than a threshold amount. The program is
