Less Is More

Leider ist der Eintrag nur auf English verfügbar.What's true for design in general certainly is true for software design in particular: Less is more - or paraphrasing Dieter Rams - "Write less software in order to write better software." A few weeks ago I read this interesting article by web accessibility consultant Heydon Pickering. In this blog post he argues that the only foolproof way of writing performant web applications is to write less code. Sure, all that fancy minification, transpiling, JIT ...

Daily Standup Meetings: Anti-patterns And What to Do About Them

Leider ist der Eintrag nur auf English verfügbar.Daily standup meetings are a mainstay of agile software development methods, such as XP, Kanban (which used to be an inventory control system having originated at Toyota) and Scrum, of course. Given that agile development methods are by far the most dominant ones in the software industry today, it should come as no surprise that daily standup meetings are a common feature of software development processes these days. These meetings basically serve the purpose of informing ...

Libraries.io and Dependency CI: Open Source Library Discovery and Dependency QA

Recently, I came across Libraries.io and its companion service Dependency CI. Libraries.io is an open source library catalogue that helps you find new libraries and keep track of the ones you already use in your projects. Once set up with a GitHub project, the service monitors the repository and notifies you in case there's a new version of a dependency available. Building upon this, Dependency CI is a continuous integration service that offers 'automatic compliance testing for all of the dependencies in your ...

Follow-up on “Accounting in 2016”

Leider ist der Eintrag nur auf English verfügbar.Two months ago, I wrote an article on how accounting in 2016 still is a manual and tedious process. What made me write this article in the first place was the problem that I couldn't automatically get the bank account statements for my business account into my accounting software because my bank's online banking service and my accounting software have incompatible import / export file formats and neither exposes a public API for facilitating ...

BedquiltDB – A JSON document store for PostgreSQL

Leider ist der Eintrag nur auf English verfügbar.BedquiltDB is a recently released PostgreSQL extension (written mostly in PL/pgSQL) that leverages PostgreSQL's relatively new jsonb column type (available since version 9.4) to provide a MongoDB-like NoSQL document store and API on top of a PostgreSQL database. There are a few benefits to this approach. First, this allows you to start a project with a comparatively simple document-oriented API that lends itself to many use cases in terms of modern web applications. While you get ...

Sharing and exploring data models and database patterns

Leider ist der Eintrag nur auf English verfügbar.Somewhat in the vein of last week's post, I'd like to share a new service called dbpatterns with you. dbpatterns allows you to create ER models in the browser and share them with other users. If a particular pattern or model suits your needs you can directly export its DDL for PostgreSQL, SQLite, MySQL or Oracle RDBMS. I really appreciate the idea of promoting and sharing best practices for database systems. While object-oriented software design ...

Hands-on SQL Tips: Sentinels And Window Functions

Leider ist der Eintrag nur auf English verfügbar.Sometimes when displaying data in an application you want the amount of data (rows, individual data points etc.) to be limited for the app to stay responsive and to allow the user to more easily scan and browse the data set. In SQL this is commonly done using a LIMIT statement: [crayon-68cffe6662fae909676029/] Now, what if you want to not only display the data but also inform the user in case the total number of rows in ...

Accounting in 2016 – Still a manual and tedious process

Leider ist der Eintrag nur auf English verfügbar.The past few weeks I've been struggling with automating my accounting, invoicing and banking processes to the point I don't really have to think about it anymore. Currently, a lot of my accounting-related processes are still way too manual for my liking. Being both a virtuous, lazy programmer and an entrepreneur I'd like to automate every process that can be automated at reasonable cost, especially if that process doesn't generate any revenue. Now, as far ...

Varying Degrees Of Software Quality And What To Do About It

Leider ist der Eintrag nur auf English verfügbar.When working on client projects I come across copious amounts of source code, which sometimes is very well-maintained, sometimes less so. The various code bases are as diverse as their owners and respective stakeholders: A few come with an inherent sense of quality, lots of unit tests serving as the specification for the product. They're typically delightful to maintain and extend. Some though at times leave the impression of having been cobbled together in a rather ...

Analyzing Large Datasets With SQL

Leider ist der Eintrag nur auf English verfügbar.As part of a web application I've created for a client, I've been working on efficient analysis of somewhat large datasets for some time now. This analysis often involves complexing grouping, clustering and value aggregation. SQL and PostgreSQL aggregate functions in particular come in quite handy when dealing with that kind of challenge. While RDBMS and SQL certainly are useful already just for keeping and retrieving data, i.e. for running your usual CRUD operation, those ...
