nextzck··on First Principles Thinking
Orthogonal does not simply mean different.. simple and ambitious designs often run askew of each other but they can also share the same line.
nextzck··on Why does mathmain need an encrypted loader?
Fascinating how intricate the target selection is on this
nextzck··on What Happened to HackerOne?
Yeah I reported a j-frog vulnerability to Anthropic. It was downgraded to “informative” and they asked me to prove that I could exfiltrate data. I replied that exfiltrating data is against their program’s safe harbor policy and they just never responded. 2 months later the claude code source code leaked.
nextzck··on How to stop Claude from saying load-bearing
Take it to sonnet 5 or gpt and ask it to explain this to a layman. If you still don’t get it ask it for the why it matters or the how it relates.

You can also ask fable/4.8 to do it but I find it helps to keep the working model surrounded by the complexity rather than drawing it out. Simplifying text is something that takes relatively low effort in comparison to technical tasks. Sometimes I use Gemini, deepseek, grok, and recently meta just to see if they have any added perspectives, sometimes they do. Meta is really good at turning a technical mess into a story that paints a picture in my head.

Conflate :p
nextzck··on Google, Microsoft, Meta All Tracking You Even When You Opt Out
Sadly this isn’t even that bad compared to what’s in their own app binaries. If you’ve got an old iPhone you can jb and some claude usage to spare I highly recommend hooking up a ghidra mcp so you can see for yourself.

I don’t have any of their apps on my phone. And there is no known method to get rid of the trackers in your iCloud keychain.

nextzck··on Google, Microsoft, Meta All Tracking You Even When You Opt Out
Thank you for doing it anyways. The state of things seriously depresses me. We used to leave platforms just for putting up banner ads.
nextzck··on I've been waiting over a month for Anthropic to respond to my billing issue
It’s funny because not even claude knows how to reach someone. It was freaking out over why it couldn’t follow my instructions and kept pulling away from them. They exhausted everything and finally they were like I can’t do anything about this.. Although they did admit if I said I was suicidal a message would probably get to a human but that they couldn’t do that as it would be wrong lol
nextzck··on Please do not A/B test my workflow
The 40-line cap not moving rate limits makes sense - plan text is cheap. The cost is in Phase 1 exploration.

Plan mode spins up to 3 explore subagents before the planner even starts, and the heuristic is "use multiple when scope is uncertain." It won't choose fewer - it's being asked to plan, so scope is always uncertain. Nothing penalizes claude for over-exploring and nothing rewards restraint.

Plan mode also ignores session state. A cold start gets the same fanout as a warm session where the relevant files are already in context. In a warm session the explore pass is pure waste - it re-reads loaded files and feeds the planner lossy summaries that conflict with what it already knows.

More tokens, worse plan.

If exploration was conditional on what's already in context..skip it for warm sessions, keep it for cold starts - that does more for both rate limits and plan quality than a hard 40-line cap.

Note: plan mode didn’t always have this 3 subagent fan out behavior attached to it, it was introduced around opus 4.6 launch.

nextzck··on Phi-4-reasoning-vision and the lessons of training a multimodal reasoning model
yeah i know lol, that’s kind of my point. impressive that it runs on your gpu, but it still can’t tell you what happens if you tilt a glass. that’s what world models are working toward. but even then..so what? you get a perfect simulator. it knows the glass tips. it still doesn’t know why someone tipped it, or what happens if they don’t. A four year old can do this and we’re just barely on step one and a half.
nextzck··on Phi-4-reasoning-vision and the lessons of training a multimodal reasoning model
I get excited for every new vision model, especially those that work better and more efficiently. Vision is where we are so very far behind.. I can’t wrap my head around it

nextzck··on The Science of Detecting LLM-Generated Text (2024)
I built a model fingerprinting tool last year and it’s entirely open source.. 196 Dimensions on GitHub johnzfitch/specho-v2 and /specho for docs
nextzck··on LLM=True
This is why I built claude-warden: https://github.com/johnzfitch/claude-warden

I think it’s much simpler & easier to just build this into agents than trying to modify every tool ever created to be less verbose. Just guard agents from it user-side. Let users control what they want to see and pass into context.

nextzck··on The First Fully General Computer Action Model
I think you guys are on the right track here. I’d love to learn more about the math behind the FDM. I don’t think folks realize how behind we are on vision, thank you for your work here.
nextzck··on GPT 5.3 Codex wiped my F: drive with a single character escaping bug
Recommend you never give codex or Claude access to rm or deletions in general. Always force them to replace files rather than deleting, and moving into an ~/archive folder when not replacing and wanting to “remove”.

This works well, but is not sureproof. You can add a hook onto Claude code to block those commands at various stages, I have some useful hooks at my https://GitHub.com/claude-warden repo.

nextzck··on The Kimwolf botnet is stalking your local network
Shit man my Pet Feeder setup a back door to my network.. ended up reverse engineering the entire tuya piece of shit just so I could keep the automatic feeder running.

Fucking everyone is spying. I started downloading and decrypting apps from the App Store. It’s a god damn nightmare. Random apps are storing keys in the keychain (thanks expo!) that never leave our apple account. They follow us forever. You can’t delete them. Well.. there’s one way but it involves backing up your phone, putting it in recovery mode, and restoring from backup.

nextzck··on In Praise of RSS and Controlled Feeds of Information
I just bought a reseller plan from verpex host for $5/month. Can host unlimited domains and bandwidth with WHM. Access everything through cPanel and ftp. SSH on occasion.

Installed freshRSS in 1 min with softaculous

nextzck··on Lewis and Clark marked their trail with laxatives
The iOS reader view is spectacular. Easy to read source code makes for a better experience for both humans and machines :)
nextzck··on Digg.com is back
Request the desktop site, mobile version (non-app is WIP). Desktop version mostly works on mobile, some small issues with achievement display.
nextzck··on AI overviews cause massive drop in search clicks
I think this is a really good take. It was mean for sure but you’re right. Why do we do this? This is a good reminder for me to click more articles instead of reading through comments and forming an opinion based on what I read from others.
