Freshworks to buy Torii to track SaaS and AI spending
Freshworks has agreed to acquire Torii, a startup that shows companies which software and AI tools their staff use and what those tools cost. The deal was announced on October 12, 2026, and the price was not disclosed. Freshworks expects it to close in the fourth quarter of its 2026 fiscal year. The bet is that AI tools, billed by usage, have become a cost that IT teams can no longer track by hand. Freshworks, which is listed on Nasdaq, signed a definitive agreement to buy Torii, according to it

URL Encoding (Percent-Encoding) Explained: encodeURIComponent, Spaces, and Double Encoding
URLs can only contain a limited set of characters. To include anything else, such as spaces, accented letters, or symbols with special meaning, they are converted to percent-encoding: a percent sign followed by two hexadecimal digits representing the byte. Text is first converted to bytes using UTF-8, and each byte that isn't allowed is written as %XX. A space is the byte 0x20, so it becomes %20. The letter e with an acute accent takes two bytes in UTF-8, so it becomes %C3%A9. hello world -> hel

RAG Tenant Isolation Inside the Vector Index
Put the user filter inside the vector search itself. If you search everything and remove other people’s chunks afterwards, those chunks still use up the slots you asked for, and one forgotten line of code puts a stranger’s document into someone else’s answer. The obvious way to build a multi user RAG app is to search the whole collection, take the best matches, and throw away anything that does not belong to the current user.
