Last week I announced that we're finally killing off RC4 in the Windows Kerberos stack.

This has been a long time coming, so much so that we've been working on it for more than a decade, albeit off and on as we sometimes had to target other more pressing issues.

What does this mean?
Beyond RC4 for Windows authentication
As organizations face an evolving threat landscape, strengthening Windows authentication is more critical than ever.

Wow. I can't believe it's live. I waited forever for Azure Code Signing (earlier name of this) to emerge in preview after the deprecation of the Device Guard Signing Service left us needing this, but then it never came for years and I eventually lost sight of it. Glad it's here at last I guess.

We did a thing!

DES (not even 3DES) has been a pain in our necks for years, but we couldn't remove it for compat reasons. It required special config to use so it's not dangerous out of the box, but it's still just...ugh, DES.

Anyway, we said enough is enough and now the code is getting deleted.

NEW: Multiple researchers โ€” independent and crypto monitoring firms โ€” are accusing North Korean hackers of stealing $1.4 billion in crypto from Bybit.

Attribution is based on link to previous hacks and "characteristic pattern" of laundering the funds.

Microsoft's big quantum gamble pays off: they were harder to build (and about as hard to understand!) but Microsoft's topological qubits are more effective, easier to control - and will probably help design their own replacements.

Finding the right chunk size (and the related delimiter(s) to parse on) can take some experimentation. Ultimately there is a whole art to this that is common to the world of traditional indexing technologies, but your data may submit well to something cheap/cheerful like this
January 13, 2025 at 6:20 PM
There are frameworks/services to help with it if you have the appetite to dive in. Otherwise you can find delimiters to parse on (I find HTML is more reliable than MD), treat each as your chunk, verify those chunks will fit with your embeddings service, then store those embeddings in your vector DB
