Build a Kaomoji Picker With JavaScript Clipboard Copying

·2 views

A DEV Community tutorial shows how to build a small kaomoji picker that copies text faces to the clipboard with vanilla JavaScript. It uses navigator.clipboard.writeText(), which requires HTTPS or a local development server and resolves only after the copy succeeds. The example pairs the copy behavior with a visible focus outline, a polite status message, and a manual-copy text field for when automatic copying is unavailable. The author notes the same pattern can be reused for coupon codes, command-line snippets, and invitation links. The project is designed without frameworks, icon libraries, or build tools.

Android 'no internet' fault traced to rogue IPv6 router advertisements from a 5G router

A user found that their Android phone showed Wi-Fi as connected but without internet, while other devices worked normally. After isolating the problem, they traced it to a Huawei 5G router (CPE) that was broadcasting IPv6 router advertisements despite being set to LAN-only mode. Disconnecting the device made the phone's issue disappear, and reconnecting brought it back. The author explains that Android's connectivity check depends on reaching its servers, and that stray IPv6 gateway announcements can redirect the phone's traffic into a dead end. The article describes how to detect these advertisements using rdisc6 or tcpdump on the same network segment.

Debugging interviews reward investigation process over a lucky first patch

Live debugging rounds on broken UIs or unfamiliar repos are evaluated on how the candidate investigates, not on how quickly they reach a working fix. Recommended practice is to restate expected versus actual behavior, identify the layer where the fault likely sits, form one testable hypothesis, and run the cheapest probe before editing code. Guides from several interview-prep sources emphasize this sequence over rewriting components or making silent, trial-and-error changes. Interviewers tend to watch how candidates narrow the search space, and a patch that hides the symptom without finding the root cause can score poorly. Some employers restrict AI or external tools during these rounds, so candidates are advised to confirm the rules with the recruiter beforehand.

Why the key skill in AI-driven engineering is knowing when to reject AI proposals

AI tools can now propose architectures, split work into tasks, write code, and prepare deployments, prompting new methodologies such as AWS's AI-Driven Development Lifecycle. The author argues that the decisive question is who actually makes the engineering judgments, not how fast AI can generate output. In this view, the most valuable human contribution is the authority to reject proposals, set constraints, request alternatives, and halt execution. Without that authority, human oversight risks becoming a ceremonial approval step. The piece illustrates the danger with an example of an agent proposing an overly complex design, such as adding Kafka, Redis, and a new microservice for a simple reservation feature.

Study Finds Insects Do Not Swarm Around LED Lights

A blog post published on Birds Outside My Window argues that insects do not gather in swarms around LED lights as they do around older light sources. The article is discussed on Hacker News, where it has drawn modest attention. The text available provides only the article link and engagement figures, so the specific evidence and methods behind the claim cannot be confirmed from this source. Readers would need to consult the original article for details on how the conclusion was reached.
