Dati interessanti su Setlist.fm:

Show by show, user entry by user entry, Setlist.fm exploded. In 2012, the site had a database of more than 400,000 set lists for 24,000 artists and reached 1.5 million people a month. Now, it has more than 9 million set lists for 400,000 artists, with 80 million users a year, according to Live Nation. Someone creates a new set list every 20 seconds. Fleischer emphasized that people stay on the site for an average of roughly eight minutes: “It’s a really heavily engaged community.”

Setlist.fm carries advertisements, but that income probably accounted for only a tiny portion of the $896 million in profit its parent company, Live Nation, posted last year. A corporate behemoth, Live Nation is the world’s largest concert promoter and the owner of Ticketmaster. The company does not break out revenue or earnings for Setlist.fm.

Azure ha problemi, l'app IO ha problemi, i documenti offline non funzionano. C'è già una PR di fix, "rare condition".

Confermato che Bending Spoons compra AOL:

Bending Spoons said its approach for AOL and other investments is to revamp and retain businesses. AOL has around eight million daily active users and a high customer retention rate, it said. Its main business lines include software for internet privacy and protection and the AOL.com website and email domain.

AOL generates around $400 million in annual earnings before interest, taxes, depreciation and amortization, the Journal previously reported. Revenue is north

Il traffico DNS è dominato dai domini .com:

Storia molto interessante di scaling: come Nanit ha risparmiato 500mila $ all'anno implementando un S3 in memoria, e i problemi di scaling (networking e memory leak) incontrati una volta deployato con il traffico in produzione di diversi GB/s.

Aggiungere una CDN o in generale avvicinare l'edge all'utente finale non sembra avere impatto in sulla latenza in presenza di una origin dinamica (rispetto a connettersi direttamente alla origin).

Mi sarei aspettato che fasi delicate come handshake TCP/TLS beneficiassero della vicinanza dell'edge e che la connessione CDN-origin fosse di qualità migliore, e invece:

Non una prova definitiva ovviamente.

Anthropic punta sul B2B, mentre OpenAI domina il mercato di massa consumer:

Anthropic has generated much less mass-market appeal. The company has said about 80% of its revenue comes from corporate customers. Last month it said it had some 300,000 of them.

Anthropic is also surprisingly close to OpenAI when it comes to revenue. The company is already at a $7 billion annual run rate and expects to get to $9 billion by the end of the year—a big lead over its better-known rival in revenue per user.

Today, us-east-1 is the single largest AWS region. It generates an estimated 2.5GW capacity spread across 6 availability zones (AZs) and 158 data centers. In comparison, the second-largest region is us-west-1 in Oregon, with an estimated 1.7GW capacity spread across 4 availability zones (AZs) and 48 data centers. Not only is us-west-1 about smaller than us-east-1, but it also charges higher per-instance prices than us-east-1.

Waymo con la neve, questo inverno è quello decisivo e i taxi sono attrezzati:

In addition to better data, Waymo is exploring other solutions to help its robotaxis navigate slicker, slushier streets. For example, tiny mechanical wipers have been installed to help clear snow off the vehicle’s rooftop lidar sensor. More powerful heaters are also included to help defrost all the sensors. Waymo’s current system is already trained on icy road conditions and can handle challenges like black ice.

I taxi comunicano tra loro per comunicare situazioni di pericolo:

Each vehicle in its fleet records this data while out on the road, like a mobile weather station, he said. “Let’s say the vehicle encounters a slippery patch,” Chen said. “It’ll actually send that information to the rest of the fleet and now other other vehicles in the fleet know that that particular location is slippery.”

Le email di risposta dell'assistenza TreC+ (fascicolo sanitario elettronico della provincia di Trento) arrivano da supporto.trec@dedagroup.it:

Ma c'è un Reply-To verso easyredmine@dedagroup.it, per cui se nel client email si preme "rispondi" si risponde a quest'ultimo indirizzo email.

Spoiler: l'indirizzo email non esiste. L'email torna indietro come bounce subito dopo, e il messaggio di rimbalzo finisce però in spam perché il dominio ha una policy DMARC di reject ma il messaggio non è autenticato con DKIM né è presente un record SPF.

Anche il NIC, registro domini .IT, attiverà il servizio RDAP sostitutivo di WHOIS. RDAP è già obbligatorio da quest'anno per tutte le gTLD ma non per le ccTLD che non seguono le regole dell'ICANN.

Al prossimo CIR, previsto per il 30 ottobre p.v., come Registro presenteremo il servizio RDAP che intendiamo attivare nei prossimi mesi.

MinIO sta diventando crescentemente un progetto prevalentemente commerciale:

• MinIO removed web management features from its open-source community version, forcing users to command-line tools or paid upgrades
• MinIO Community version was downgraded to basic object browser only with no account management, policy configuration, or administrative functions
• The cost of MinIO’s paid version is substantial: software and support alone cost a MINIMUM of $96,000 per year, rising to $244,032 per year for 1 PB of usable capacity, according to MinIO’s website.

Ora la versione community non è più su Docker Hub ed è sparita anche la documentazione community apparentemente.

GitHub ha un nuovo capo prodotto, Jared Palmer, ex Vercel, e dice che GitHub implementerà le stacked PR/stacked diff (stile Graphite.dev):

RE: Stacked Diffs on @GitHub

After discussion w @ttaylorr_b, we can implement stacked PRs/PR groups already (in fact we kind of do with Copilot) but restacking (automatically fanning out changes from the bottom of the the stack upwards) would be wildly inefficient. To do it right, we need to migrate @GitHub to use git reftables instead of packed-refs so that multi-ref updates / restacking will be O(n) instead of ngmi.

This will take some time but has been greenlit.

Molto interessante!
