ttl è un mtr con qualche funzione in più, tra cui enrichment dei dati ASN e DNS:

Key features of ttl include:

• Multi-flow probing – Enumerates all load-balanced paths (no more seeing just one path through ECMP).

• Path MTU discovery – Pinpoints exactly where fragmentation kills your jumbo frames.

• NAT detection – Reveals when a middlebox is quietly rewriting your source ports.

• Route flap alerts – Catches BGP instability as it happens by detecting path changes in real time.

• PeeringDB integration – Identifies which Internet Exchange (IX) you're crossing in your route.

• MPLS label visibility – Exposes provider LSP paths by decoding MPLS labels from ICMP responses.

• Smart loss detection – Distinguishes real packet loss from routers simply rate-limiting ICMP replies.

• Modern TUI – Features live stats, jitter calculation, ASN/GeoIP enrichment, and a sleek terminal UI (no 1990s look-and-feel).

• Scriptable output – JSON and CSV export for automating analysis or proving that yes, the problem is their network.

It’s hard to justify Tahoe icons. Partendo dalle linee guida di interfaccia umana del 1992 di Apple, una analisi molto critica delle nuove icone in macOS 26 Tahoe.

Uno degli errori principali è inserire icone per ogni azione:

Anche se non esistono sufficienti icone comprensibili da corrispondere a ogni icona, con questi risultati:

La conclusione:

In my opinion, Apple took on an impossible task: to add an icon to every menu item. There are just not enough good metaphors to do something like that.

But even if there were, the premise itself is questionable: if everything has an icon, it doesn’t mean users will find what they are looking for faster.

And even if the premise was solid, I still wish I could say: they did the best they could, given the goal. But that’s not true either: they did a poor job consistently applying the metaphors and designing the icons themselves.

normattiva2md. onData ha fatto un tool per convertire i dati di Normattiva da XML a Markdown:

Scrive inoltre onData che:

In queste settimane in cui abbiamo lavorato a normattiva2md, abbiamo scoperto una novità importante: a decorrere dal 1° gennaio 2026, i dati di Normattiva sono finalmente dati aperti. È possibile scaricarli e utilizzarli con licenza Creative Commons CC BY 4.0.

Non troviamo il link alla pagina “dati” nei menu del sito, ma l’URL si trova utilizzando i motori di ricerca: https://dati.normattiva.it/home.

pg_repack. pg_repack is a PostgreSQL extension which lets you remove bloat from tables and indexes, and optionally restore the physical order of clustered indexes. Unlike CLUSTER and VACUUM FULL it works online, without holding an exclusive lock on the processed tables during processing. pg_repack is efficient to boot, with performance comparable to using CLUSTER directly.
