raylad··on Less human AI agents, please
I haven’t noticed this sort of behavior with opus 4.6, but the first time I used 4.7 it decided to “simplify“ an existing piece of functionality rather than fixing it, which of course made it completely unusable.
raylad··on Claude Opus 4.7
That was more than one task. It was 3.

I also had Opus 4.7 and Opus 4.6 do audits of a very long document using identical prompts. I then had Codex 5.4 compare the audits. Codex found that 4.6 did a far better job and 4.7 had missed things and added spurious information.

I then asked a new session of Opus 4.7 if it agreed or disagreed with the Codex audit and it agreed with it.

I also agreed with it.

raylad··on Claude Opus 4.7
I am using 4.7 with the default extra high thinking, and it is clearly very stupid. It's worse than old Sonnet 4.5.

I had it suggest some parameters for BCFtools and it suggested parameters that would do the opposite of what I wanted to do. I pointed out the error and it apologized.

It also is not taking any initiative to check things, but wants me to check them (ie: file contents, etc.).

And it is claiming that things are "too complex" or "too difficult" when they are super easy. For instance refreshing an AWS token - somehow it couldn't figure out that you could do that in a cron task.

A really really bad downgrade. I will be using Codex more now, sadly.

raylad··on Audio tapes reveal mass rule-breaking in Milgram's obedience experiments
One explanation is that the ones who quit believed it was a real experiment and decided they wanted no part of it.

The ones who were "obedient" figured out it was fake and treated it as a game.

raylad··on Multiple Sclerosis
N-acetylglucosamine actually is effective against MS.

Article: https://www.ucihealth.org/about-us/news/2023/09/multiple-scl...

Paper: "N-acetylglucosamine inhibits inflammation and neurodegeneration markers in multiple sclerosis: a mechanistic trial"

https://pubmed.ncbi.nlm.nih.gov/37705084/

It is available fairly inexpensively as a supplement.

raylad··on Audio tapes reveal mass rule-breaking in Milgram's obedience experiments
One question is whether the participants really believed they were giving shocks to the "learners".

In college I participated in a number of psychological studies that were similarly deceptive, where one of the other participants was obviously (to me) an actor, or, sometimes, a pre-recorded video.

At least one of the studies I participated in was quite like the Milgram study described in the article, where I was supposed to punish another participant. It was very obvious to me that this wasn't really happening, so I randomly punished or didn't punish them, and then afterwards told the researcher that I knew it was all fake.

I think many or most other people who saw through the deception probably wouldn't have let the researcher know, because it seemed somehow disrepectful to tell him.

No idea if he used my results or, as he should have done, discarded them.

raylad··on I'm losing the SEO battle for my own open source project
So the real site is https://nanoclaw.dev

(putting this here for the search engines to see)

raylad··on Fix the iOS keyboard before the timer hits zero or I'm switching back to Android
Also why did they get rid of select all? Is there any excuse for that?
raylad··on Impeccable Style
"DON'T use pure white or pure black..."

This is something I hate: gray text. Designers love it but it is often very illegible because of inadequate contrast.

raylad··on Show HN: Mantic.sh – A structural code search engine for AI agents
MANTIC_IGNORE_PATTERNS seems not to be implemented, or am I missing something?
raylad··on Maybe the default settings are too high
Or, never play it faster than you can play it perfectly.
raylad··on Cloth Simulation
Feels more like a spiderweb simulation. The fibers are sticky and stretchy.
raylad··on Bag of words, have mercy on us
I tested this with ChatGPT-5.1 and Gemini 3.0. Both correctly (according to Wikipedia at least) stated that George Olshevsky assigned it to its own genus in 1991.

This is because there are many words about how to do web searches.

raylad··on Claude 4.5 Opus' Soul Document
It’s a lovely set of aspirations for how a model should behave. But unclear to me is the extent to which expressing those aspirations actually compels the model to follow them.
raylad··on Where's the shovelware? Why AI coding claims don't add up
Some of the projects I've been doing are for myself in other businesses, automating processes that were time consuming or... annoying.

Others are for start-ups that are pre-money, pre-revenue where I can build things myself without having to deal with hiring people.

In a larger organization, certainly I'd delegate to other people, but if it's just for me or new unfunded start-ups, this is working out very well.

And it's not that I "can no longer program". I could program, it's just that I don't find the nuts and bolts of it as interesting as I used to and am more focused on functionality, algorithm, and UI.

raylad··on Where's the shovelware? Why AI coding claims don't add up
I used to be a full-time developer back in the day. Then I was a manager. Then I was a CTO. I stopped doing the day-to-day development and even stopped micro-managing the detailed design.

When I tried to code again, I found I didn't really have the patience for it -- having to learn new frameworks, APIs, languages, tricky little details, I used to find it engrossing: it had become annoying.

But with tools like Claude Code and my knowledge about how software should be designed and how things should work, I am able to develop big systems again.

I'm not 20% more productive than I was. I'm not 10x more productive than I was either. I'm infinity times more productive because I wouldn't be doing it at all otherwise, realistically: I'd either hire someone to do it, or not do it, if it wasn't important enough to go through the trouble to hire someone.

Sure, if you are a great developer and spend all day coding and love it, these tools may just be a hindrance. But if you otherwise wouldn't do it at all they are the opposite of that.

raylad··on Claude Code: Now in Beta in Zed
Does this use the API or can it use the Claude subscription?

That wasn't stated or perhaps I missed it.

raylad··on White House in Talks with Intel for 10% U.S. Government Stake
We need to be doing much, much more of this so that the country has ownership of substantial percentages of the critical infrastructure, including AI. That seems to be one of the only ways that the citizens in general will be able to share in the fruits of the technology, similarly to how Alaskan citizens get payments from petroleum.
raylad··on Claude says “You're absolutely right!” about everything
Claude Sonnet 4.0 didn't say "nope" to the same prompt but also didn't agree. It replied:

Actually, 24V control signals in HVAC are typically AC, not DC. Most residential and commercial HVAC systems use 24VAC for their control circuits. This 24VAC comes from a step-down transformer that reduces the standard line voltage (120V or 240V AC) down to 24VAC. The reasons for using AC include:

* Safety - Lower voltage reduces shock hazard

* Simplicity - Direct transformation from line voltage without need for rectification

* Cost - AC transformers are inexpensive and reliable

* Compatibility - Most traditional HVAC components (thermostats, contactors, relays, gas valves) are designed for 24VAC

However, you will find 24VDC in some applications:

* Modern digital/smart thermostats and controls

* Building automation systems (BAS)

* Some newer high-efficiency equipment

* Systems that need to interface with low-voltage DC electronics

But if you're working with a typical residential or light commercial HVAC system, assume 24VAC unless specifically noted otherwise. Always verify with a multimeter set to AC voltage when troubleshooting!

raylad··on Launch HN: Golpo (YC S25) – AI-generated explainer videos
Feedback on the text: I find the way that the text generates randomly across the line very distracting because I (and I think most people) read from left to right. Having letters appear randomly is much more difficult to follow.

Are there options to have the text appear differently?

raylad··on Qodo CLI agent scores 71.2% on SWE-bench Verified
If it's really better than Claude Code while using Sonnet 4.0, then I'd pay a monthly fee for it, but only if I can use my Claude subscription the same way Claude Code does.

I do not want to pay API charges or be limited to a fixed number of "credits" per month.

raylad··on Optimizing my sleep around Claude usage limits
You can get another $20/mo account and switch between them with /login. It won't give you continuous coding probably, but at least you can go for twice as long with a shorter wait afterwards.

I find that each account gives me 1-2 hours of coding in Claude Code usually.

raylad··on Kyoto University team develops pain reliever comparable to morphine
It works by causing a release of noadrenalin.

Prediction: It will end up being used by the military and/or fighters to provide instantaneous muscle strength coupled with pain relief from overexertion.

raylad··on 2,500-year-old Siberian 'ice mummy' had intricate tattoos, imaging reveals
The designs are beautiful but there’s no evidence at all of perspective which is a specific technique using a vanishing point.
raylad··on FDA has approved Yeztugo, a drug that provides protection against HIV infection
This is great information and obviously new to me. I had thought it only interfered with cap formation but it appears to also interfere with capsid penetration of the nucleus and therefore integration of the virus with the host cell genome.

So obviously I retract everything I said above .

raylad··on FDA has approved Yeztugo, a drug that provides protection against HIV infection
The problem with this drug is that it inhibits one of the final stages in viral replication. This means that before it can work the virus has already infected the cell and added its RNA to the host cells DNA permanently.

So if a patient is exposed to HIV while on the drug, this will not prevent their cells from being infected with the virus. The infected cells will not subsequently create any virus, and therefore additional cells will not be infected, however nothing prevents actual exogenous HIV from infecting cells while on this drug.

That means that if someone discontinues the drug, cells that have been infected with HIV during the time they were on the drug can start producing it causing AIDS.

It’s great that there’s a drug that works as well as this for chronic use, but nobody should think that it’s actually preventing infection. It’s allowing infection but inhibiting viral replication post infection.

raylad··on Replit's CEO apologizes after its AI agent wiped a company's code base
This happened to me with Claude code, although on my local machine and not with the production database.

I had it work on one set of tasks while monitoring and approving all the diffs and other actions. I tell it to use test driven development which seems to help a lot, assuming you specify what tests should be done at a minimum, and tell it the goal is to make the code past the tests, not to make the tests pass the code.

After it successfully completed a set of tasks, I decided to go to sleep and let it work on the next set. In the morning, my database was completely wiped.

I did not interrogate it as to why it did what it did, but could see that it thrashed around on one of the tasks, tried to apply some database migrations, failed, and then ended up re-initializing the database.

Needless to say, I am now back to reviewing changes and not letting Claude run unattended.

raylad··on Claude Code Pro Limit? Hack It While You Sleep
Seems convenient. I have a couple of different Claude accounts, so I switched between them when one gets exhausted. Sometimes they both get exhausted. If other people have a couple of accounts then that would be a nice feature to add to this: switching between accounts and then resuming when either of them becomes available again.
raylad··on Show HN: New Ensō – first public beta
I read the first few screens and still had no idea what we were talking about. I came to the conclusion that maybe it was a paperwhite display of some sort.

Apparently it’s an app. I suppose that blog post is only for people who already know what the app is?

raylad··on Requiem for a Solar Plant
If the author is reading this, and hasn't looked into it yet, there is a reasonable probability that he has a parasite infection.

My family lived in rural Malaysia for some time and some of us had similar symptoms for years before it was determined that parasites were at fault. Once they were killed, recovery was fairly quick.
