• OMG Ubuntu ☛ Fix HEIC images not loading in Ubuntu 26.04 LTS

  If your HEIC photos show a “Could not load image” error in Ubuntu 26.04’s Image Viewer, you’re not alone – it’s an intentional breakage, albeit one that’s easy to fix. HEIC files are a variant of HEIF which use H.265/HEVC compression. If you own an iPhone or a newer Android device, the stock camera app uses this format by default. But Ubuntu 26.04 LTS longer preinstalls a decoder library for HEIC (though more accurately, it’s tweaked dependency chains to ensure one is no longer pulled in).

• TecMint ☛ How to Copy Millions of Files Faster in Linux

  The cp command does exactly one thing well: it copies files, but it gives you no progress indicator, no rate limiting, no resume support, and no built-in checksum verification.

• APNIC ☛ Repairing the RPKIViews H1 2026 archives

  The rpkispool format revolves around a data structure called Canonical Cache Representation (CCR). To fully appreciate the function of CCRs, one should first consider the overall dimensions of the RPKI distributed database: As of April 2026, at any given time, a hot RPKI cache is around 1GB of Distinguished Encoding Rules (DER) — encoded data across ~ 515,000 objects.

  *slaps stylesheet* This front-end has many years on it, but a lick of paint and it's good to go.

  I've released the changes; see the highlights below.

• linuxcapable

  • Linux Capable ☛ How to Fix Nginx 404 Not Found

  • Linux Capable ☛ How to Fix Nginx 502 Bad Gateway

    An Nginx 502 Bad Gateway error means Nginx accepted the client request but could not get a valid response from the upstream service. The upstream might be a reverse-proxied application, a PHP-FPM pool, a container, a private backend server, or another proxy layer in front of your origin.

  • Linux Capable ☛ Bash Check if File or Directory Exists

    Good Bash scripts check paths before they assume a config file, log directory, upload target, or optional dependency is available.
