Visualizing What a Neural Network Thinks

Aggregated on: Sun Jan 16 2022 03:04:38 GMT+0000 (Coordinated Universal Time)

Ok, Neural Networks don’t really "think", but they surely have an opinion. If you feed a Convolutional Neural Network, let’s say, a classifier with an image, it will tell you what it "thinks" is there, but sometimes you might wonder what contributed to that particular decision, as an attempt to try to "debug" your network. For example, when designing a gender classification Neural Network, I noticed that the network was paying attention to the ears, and it learned to recognize them. It turned out ears can be used to detect gender, so it was a good sign that my network was looking for them.

10 Rules To Integrate Third-Party Scripts

Aggregated on: Sat Jan 15 2022 16:34:38 GMT+0000 (Coordinated Universal Time)

Introduction Third-party scripts can cause negative load-time effects. Why is this an issue? Well, in Google’s view, a poorly-optimized page should not rank highly. Instead, search results should favor pages with fundamental design strengths — including JavaScript minification, rapid execution time, and render-friendly scripting. In reflection of this belief, Google has planned the gradual release of a major update to its search algorithm that is scheduled for June through August of 2021. This update will increase the importance of a page’s loading speed as a contributing factor to a web page’s overall ranking on Google’s search results page. As a result, how third-party scripts impact page load times is becoming more important than ever.

Building with Open Policy Agent (OPA) for Better Policy as Code

Aggregated on: Fri Jan 14 2022 22:04:38 GMT+0000 (Coordinated Universal Time)

When we hear the term Policy as Code, it’s for the most part associated with the enforcement aspects of applying policy at scale within organizations. Whether in the context of GitOps or just popular open source projects like Open Policy Agent (OPA), applying global policy is the end goal. However, OPA as an open source project is quite unique in its capabilities. There is a whole pre-enforcement set of tools that provide incredible insights into our systems that have long been overlooked. A new wave of infrastructure drift has arisen in the cloud world due to the layers of abstraction and automation. When building Firefly, we channeled the power of OPA as a policy discovery engine, not just an enforcement mechanism.

Don't Make Me Think (More Than Needed)

Aggregated on: Fri Jan 14 2022 15:34:38 GMT+0000 (Coordinated Universal Time)

In three earlier posts, I drew a lighthearted comparison between types of developers, two veteran film directors, the relentless perfectionist Stanley Kubrick and passionate amateur Woody Allen as well as comic book anti-hero Gomer Goof as the disaster artist. I wanted to highlight overlapping tendencies, not suggest strict categories. Stereotypes like Roy and Moss from the tv show The IT Crowd work great in fiction, or the evil and funny Nedry (anagram for nerdy, LOL) from the first Jurassic Park movie? If you do find persons matching the cliché of the behaviorally maladjusted yet genius workaholic for real, they are no fun to deal with. This is not to deny the fact that men in their thirties do take up most of the Bell curve, which dominates the perception of the programming community as a poorly diversified group. It certainly does in the Netherlands. We’re more old-fashioned than you think.

Ways to Avoid Dependencies: Tips for Product Engineering Teams

Aggregated on: Fri Jan 14 2022 08:49:37 GMT+0000 (Coordinated Universal Time)

Dependencies cause chaos on delivery and destroy predictability. Use the "independent executor" model. These are weightless conditions that can increase your plans. Independent Executor Model We need things from other teams because they are the owners of the area we need to do work in. And it is natural when there is a temptation to depend on them and wait for them to provide something for you. For example, there is a need to find a team to add a field into the API or to build a new one. Sometimes, you can’t show what you require without these changes.
