Solo Developer Hides Instagram Reels in WKWebView, Detects Silent CSS Failures

·10 views

A solo developer in Japan built minulo, an iPhone app that lets users reply to Instagram DMs without seeing Reels or Shorts. The app loads Instagram and similar sites in a WKWebView and uses CSS and JavaScript to remove the Reels entry points. The developer found that CSS rules inject in two stages to prevent a flash of content, and that wrapping history functions repeatedly caused slowdowns and freezes. Hiding elements with display:none could also blank out virtualized feeds, so the developer tags elements and preserves their height instead. To catch silent selector failures after site markup changes, the app periodically counts matches and flags rules that stop matching.

Atlassian's usage-based pricing could add about a quarter to 200-seat costs

Atlassian is introducing usage-based charges on several metered capabilities, with allowances pooled across an organization and overages billed starting December 3, 2026. An analysis of a 200-seat company on Jira and Confluence Standard estimates roughly $7,464 a year in added usage costs on top of $30,500 in list-price seats, mostly from Rovo AI credits. Automation usage was found to add very little, at under $50 a month in the heaviest scenario. The analysis also found that Teamwork Collection Standard is cheaper than Jira plus Confluence Standard at 50, 200 and 500 seats. Figures are based on Atlassian's published pricing as of October 15, 2026, and the author's own test organization.

Firefox Dark Mode Options: Dark Reader, NightOwl, and Built-In Settings Compared

Bright web pages at night can cause eye strain, and Firefox users have several ways to switch to darker displays. Enabling dark mode in the operating system helps sites that support the prefers-color-scheme setting, though sites without dark support stay white. Dark Reader works on virtually any site with extensive customization but can cause visual glitches and uses more CPU. NightOwl offers a lightweight, pure-CSS alternative with fewer glitches but limited per-site control and no effect on sites lacking dark support.

How to Fix Firefox Slowness, Crashes, and Broken Extensions

Firefox problems often have quick fixes, so it's worth trying troubleshooting steps before reinstalling or switching browsers. Starting in Safe Mode, which temporarily disables extensions and default settings, helps reveal whether an add-on is the cause. If issues persist, users can check active extensions, hardware acceleration, and GPU rendering status, and consider reducing open tabs to lower memory use. For site-specific problems, the guide suggests reviewing content blockers, codec support, DNS settings, and cache. As a last resort, Refreshing Firefox or creating a new profile can reset the browser while preserving key data like bookmarks and passwords.

loudness-tts ranks open Piper voices and normalizes text for Python and the browser

Open text-to-speech models now run quickly on ordinary hardware, but their output often sounds wrong. The developers of Loudness.ai built loudness-tts to address voice quality, licensing, and text handling problems. They tested 1,683 Piper voices for naturalness and clarity, and the voice auto-selection picks the best voice with a commercially usable licence. A rule layer converts money, dates, units, and abbreviations into spoken words in English and Spanish, while keeping word timings aligned with the source text for subtitles. The project offers matching Python and JavaScript editions, the latter running in Node, Bun, Deno, and the browser, and it is free and open source.
