Fantastic Symbols and Where to Find Them (Part 1)

,

Symbolization is a technique that allows you to translate machine memory addresses to human-readable symbol information (symbols).

Why do we need to read what programs do anyways? We usually do not need to translate everything to a human-readable format when things run smoothly. But when things go south, we need to understand what is going on under the hood. Symbolization is needed by introspection tools like debuggers, profilers, core dumps, or any other program that needs to trace the execution of another program. While a target program is executing on a machine, these types of programs capture the stack traces of the program that is being executed.

PostgreSQL uses many algorithms to join tables. In this article, we will see how joins work behind the scenes from a planner perspective and understand how to optimize them.

Exciting New Tools For Designers, Holidays 2021

,

The year’s winding down as everyone segues into a much-needed holiday R&R. But that doesn’t mean there aren’t some awesome new tools and resources for website design projects.

Check them out, and hit the ground running in January. Here’s what’s new for designers this holiday period. Enjoy!

Fancy Border Radius Generator

Fancy Border Radius Generator is a fun tool that allows you to create exciting shapes for elements. Use the included templates or create your own border shapes and then export the CSS/HTML for a variety of uses.

Pulsetic

Pulsetic answers the question: “Is your website down?” Get website downtime alerts by phone call, SMS, email, or Slack. Create beautiful status pages and incident management reports and keep visitors (and your team) updated.

Ffflux SVG Generator

Ffflux SVG Generator makes it easy to generate fluid and organic-feeling gradients. You can use the resulting graphics as backgrounds to elements on a page to give a colorful fluid look to page elements. Choose colors and styles, then save or copy your SVG for use.

Fable

Fable is a web-based motion design platform to help you tell moving stories. It’s designed to be easy enough for beginners to use but has tools that even the most experienced motion designers can appreciate. This is a premium tool, but you can try it free.

Modern Fluid Typography Editor

Modern Fluid Typography Editor takes the guesswork out of sizing and scale for type sizes on different screens. Set a few preferences and see ranges your type styles should fall in. This typography calculator is visual and easy to use.

Emoji to Scale

Emoji to Scale is a fun look at emojis in a real-world relationship to each other. Make sure to also note the Pokemon to Scale project, which is just as much fun.

Page Flip Text Effect

Floating UI

Floating UI is a low-level library for positioning “floating” elements like tooltips, popovers, dropdowns, menus, and more. Since these types of elements float on top of the UI without disrupting the flow of content, challenges arise when positioning them. It exposes primitives, which enable a floating element to be positioned next to a given reference element while appearing in view for the user.

EdgeX Foundry on K3s (Part 2): The Initiation

,

In the first part of this series, we have seen all the pre-requisites that are needed to proceed with the hands-on. We will extend the EdgeX Foundry tutorial by Jonas Werner and deploy the EdgeX Foundry services on K3s. We have already learned that K3s will be a good lightweight solution to manage and orchestrate the EdgeX microservices. We will use the Geneva version of EdgeX Foundry.

The scope of this post is to demonstrate an Edge use case that will consume the sensor data e.g. ambient temperature. This sensor data will then be processed by EdgeXFoundry services hosted on K3s. This sensor data will be pushed to a cloud-based MQTT broker called HiveMQ. From here, the data can be stored and processed in the cloud. The configurations and manifests used in these posts are available in this repository.

Improving the Reader Experience With Adobe Embed API

,

The Adobe PDF Embed API provides a simple way for web developers to display PDFs on their web pages. While browsers provide good support for rendering PDFs, they do so in an « out of context » manner that takes over the entire screen. The PDF Embed API however lets you place a PDF within your site’s layout, providing much better control over the position and size of the rendered document. This improved experience also provides deeper integration into the PDF viewer, letting developers listen for events and perform operations on the document. In this article, I’m going to demonstrate a simple, but hopefully really useful example of this.

Imagine a large document covering many pages, for example, a textbook. Your website users, potentially students, could work with the document over many weeks while school is in session. If the document is a few hundred pages long, it would be incredibly useful to remember where they were in the document when they start reading again. While a large PDF may have bookmarks, even then they could only be for chapters or other sections, not the exact page the user last read. Luckily, the Embed API provides a method to help with this. Let’s take a look!
