Design tools have quietly become one of the most locked-in parts of a modern team’s workflow. The files live in someone else’s cloud, access is billed per editor seat, and the moment you stop paying, the door to your own work can close behind you. For a small studio or an internal team, that model […]
Last update: 25.07. I know a lot of text, but that is how I process ideas and iterate fast! You add an animated GIF to a Penpot prototype, open it in Google Chrome, and… nothing. The GIF sits there like it’s waiting for written permission to move. Then you wiggle the cursor or interact with […]
Spend a lot of time with Vikunja (cubicFUSION Vikunja Importer) lately, one thing that it is currently missing is an easy way to style the interface. Especially the task view is just one long page without any clear section separation. LET’S TWEAK IT Here a quick starting point to tweak the style quickly. You can […]
File synchronization is usually treated as a cloud problem. Put the folder in Dropbox, Google Drive, OneDrive, or iCloud, wait for everything to upload, and hope the storage quota, privacy model, transfer speed, and client support all line up with your workflow. That works for office documents. It gets awkward fast when you are syncing […]
Building a homelab is one of those things that starts with a Raspberry Pi on your desk and ends with you drilling holes in the wall at 11pm. If you’re reading this, you’ve probably hit that inflection point — the pile of switches, NAS boxes, and mini PCs is growing, and it’s time to get […]
Designing HTML emails in 2026 is still, somehow, one of the most frustrating things a developer can do. Table layouts, inline styles, Outlook’s stubbornness — it’s a timeless nightmare. That’s why drag-and-drop email builders exist, and why the open source ones are getting genuinely good. Whether you want something you can embed in your own […]
PDF operations are one of those recurring pain points that never fully go away. You need to fill a contract template, strip and rewrite document metadata before archiving, generate an invoice from an HTML template, and stamp every page with a branded header. The default answer is a SaaS API subscription that charges per document […]
Generating PDFs on a server is one of those tasks that sounds simple until you actually sit down to do it. HTML-to-PDF rendering drifts between browsers, LibreOffice headless mode is finicky to install, and most SaaS solutions charge per page once you hit volume. Gotenberg solves this cleanly: a single Docker container that bundles headless […]
FFmpeg is the swiss-army knife of media processing, but wiring it into a web application is rarely fun. You either install the binary on every worker, juggle temp directories, sanitise shell arguments, and hope nothing escapes your wrapper – or you reach for a heavy SaaS service and pay per minute of video. Aureum-Cloud/FFmpeg-API takes […]
If you have ever embedded an audio player on a podcast site, a music portfolio, or a media archive, you have probably noticed that pretty rendered waveform behind the playhead. Libraries like Wavesurfer.js and Peaks.js can draw those visuals on the client, but decoding a 60-minute MP3 in the browser is slow, memory-hungry, and unreliable […]
