Windows Showing 100% Disk Usage? Here's How to Find the Real Cause

·1 views

Windows Task Manager occasionally shows 100% disk usage even when users appear idle, causing slowdowns in applications and system responsiveness. Background processes such as Windows Update, antivirus scans, cloud synchronization, and file indexing are among the most common legitimate causes of sustained high disk activity. Identifying the specific process responsible — via Task Manager's Disk column — is more informative than reacting to the percentage alone. Low available storage on the system drive can further compound performance issues, making it advisable to maintain adequate free space. Security concerns are better investigated by looking for patterns and combinations of unusual changes rather than treating any single spike as evidence of a problem.

Developer Closes July 2026 With 24 WordPress Pull Requests Across 9 Repos

A developer contributed 24 pull requests across 9 WordPress repositories during July 2026, with WooCommerce accounting for the largest share at 10 merged PRs. A key fix addressed a log cleanup bug where WooCommerce's daily cron job deleted only 20 expired log files per run due to a missing pagination parameter, leaving excess files stranded indefinitely. Another fix corrected stale order counts in the admin panel caused by a cache shortcut that ignored custom query filters added by plugins. The most complex contribution replaced six separate REST API calls per page load with a single combined endpoint, reducing unnecessary network overhead for the WooCommerce Activity Panel and homescreen widget. The developer shared full code diffs for each change to help others understand the context and impact of each fix.

Build vs Buy: A Framework for Founders Choosing React Native App Templates

A developer-facing guide argues that most founders waste time debating whether to build a React Native app from scratch or buy a template, when the real question is where their product's differentiation lies. The framework suggests that if an app's uniqueness comes from its AI pipeline, marketplace logic, or workflow, founders should buy a template and redirect engineering effort toward those differentiators. Roughly 90% of consumer apps fall into this category, yet many founders mistakenly assume their infrastructure needs are unique enough to justify building from scratch. Full-stack templates, unlike basic UI kits, ship complete vertical stacks including database schemas, authentication, edge functions, and push notifications, saving an estimated 60-plus hours of setup work. The guide also addresses common concerns around originality and flexibility, noting that templates ship full source code and can be rebranded in an afternoon using tools like NativeWind.

How to Auto-Renew Tailscale HTTPS Certificates on PiKVM Using systemd

PiKVM users running Tailscale for remote access must manually handle HTTPS certificate renewals, as certificates obtained via 'tailscale cert' are not automatically renewed. A community-developed solution uses a systemd timer that runs daily to check whether the current certificate matches the device's Tailscale FQDN and has at least 30 days of validity remaining. If renewal is needed, the script temporarily switches PiKVM's read-only filesystem to read-write, fetches a fresh certificate using the '--min-validity=720h' flag, and replaces the nginx SSL files before restoring the filesystem to read-only. The approach aligns with official PiKVM documentation, which recommends placing Tailscale certificates in '/etc/kvmd/nginx/ssl/' and restarting the kvmd-nginx service after updates. Since Let's Encrypt certificates are valid for 90 days, triggering renewal at the 30-day mark provides a comfortable buffer against expiration.

Three key-free public APIs a developer uses daily in CI pipelines

A developer has shared a Node.js workflow that fetches trending content daily from three public APIs — Hacker News, DEV.to, and Reddit — without requiring any API keys or authentication. The script runs via GitHub Actions and feeds a content drafting pipeline, with keyless access reducing the risk of credential expiry or rotation failures in CI environments. The Hacker News Firebase API returns top story data with no rate limit documented, though parallel fetching and small delays help avoid occasional throttling. DEV.to's read-only articles endpoint allows unauthenticated access with a rate limit of 10 requests per second, while Reddit's lesser-known .json URL suffix enables listing data retrieval without OAuth, provided a valid User-Agent header is included. Each API has practical limitations around latency, uptime, or data freshness, but all three have proven reliable for once-daily automated runs over several months.
