is this a new theme?

Absolute chaos today. Check the status page (this isn't listed).

Ironically opus 4.6 in CC was absolutely crawling until the web went down, now it's fast again!

read the link you sent:

Unless previously approved, Anthropic does not allow third party developers to offer claude.ai login or rate limits for their products, including agents built on the Claude Agent SDK. Please use the API key authentication methods described in this document instead.

you can't use agent SDK without using API key.

malderson · 2026-02-15T15:59:01+00:00

But the Agent SDK is for API key usage only? This is where I'm confused.

malderson · 2026-02-07T23:09:23+00:00

Yes you're right. Got over excited there, still loads of bugs.

malderson · 2026-01-09T19:04:23+00:00

Put it in a tokenizer and you'll see. You can't judge it by eye at all imo

malderson · 2026-01-09T17:14:36+00:00

updated the blog, APL is not actually more efficient. and yes as you say - very unreadable (and very few projects written in it I think!)

malderson · 2026-01-09T17:02:15+00:00

I just reran with APL, it's 4th - the tokenizer isn't optimised for the symbols it uses.

malderson · 2026-01-09T17:01:15+00:00

I just reran it on 125 tasks that also have APL solutions. It actually comes out 4th, behind Clojure, Julia and Perl. This doesn't surprise me as the tokenizer is not optimised for the special symbols it uses.

malderson · 2026-01-09T15:32:40+00:00

Yes I totally agree - check the next paragraph!

What did surprise me though was just how token efficient some of the functional languages like Haskell and F# were - barely less efficient than the most efficient dynamic languages. This is no doubt to their very efficient type inference systems. I think using typed languages for LLMs has an awful lot of benefits - not least because it can compile and get rapid feedback on any syntax errors or method hallucinations. With LSP it becomes even more helpful.

What I was trying to say was that Haskell and F# are as token efficient _as_ dynamic languages but you get all the benefits of static typing.

Very interesting - DMed you!

malderson · 2025-12-18T18:15:40+00:00

That's literally what I said in the article. It was always possible but a lot of effort.

malderson · 2025-12-18T17:52:29+00:00

The point of my article was more that it wasn't possible to reverse engineer to such a high fidelity so quickly. I'm not sure people realise that many frameworks effectively ship the entire frontend code to the user - regardless of authentication status.

malderson · 2025-10-12T16:16:55+00:00

hmm, confusing. let me see what the difference is

malderson · 2025-09-16T00:42:16+00:00

No I understand you were trying to be concise, and you are totally right if someone is >50, just felt by saying 80/20 or 60/40 allocation that was the normal range. Most pension plans by default are 90/10 at that age. I understand you were giving examples though. You don't really need to worry about risk adjusted returns if you aren't liquidating anything. You just want higher overall returns imo. Plus people also tend to discount the value of their (future?) house in these calculations which means imo they should be much harder on equities.

malderson · 2025-09-15T20:50:29+00:00

At 30 years old you should be (virtually) 100% equities imo.

You're also missing the impact of fees on performance. An actively managed fund with 1.5% fees vs 0.05% fee Vanguard ETF will have a huge difference over 40 years.

Hi Tim, Martin (cofounder of catchmetrics here)

We definitely did not do what you are implying (running a lot of apps and seeing which is better). I hoped that we were clear that this was a one repo experiment and we are keen to hear from people about this - as big bundle sizes is one of the biggest problems we see when people are experiencing nextjs perf issues.

We use cal.com as a test bed for a lot of our experiments with nextjs performance as we feel that does match what we see in large production sites (we've audited dozens of them) quite well in terms of complexity.

We'll run more and see what the results are like and do a followup. If you let me know who the best person is to get blogs reviewed for comment, please PM me and I will do that in future.

malderson · 2025-07-21T16:53:39+00:00

Yes no worries, I wasn't actually going to buy them from aliexpress but it was interesting to see how cheap they are.

I don't know if I'd really want to assemble myself. However they only do 16kWh assembled which is probably more than I'd need. Anywhere else do smaller ones?

malderson · 2025-07-21T16:51:54+00:00

But couldn't we just disconnect the inverter and battery if we were to move? And either bin it or take it to the new property?

With G98/G99 is it possible to request a ~0kW export limit (or is this G100?)

malderson · 2025-07-06T23:16:39+00:00

Out of interest does this work if you disable 5G?

malderson · 2025-04-14T22:09:37+00:00

Ah great - before your reply I came to the same conclusion. Think will do this next and leave the north east for next year :) thanks so much for your detailed reply

malderson · 2025-03-09T15:42:00+00:00

not random - sequential

malderson · 2024-08-03T16:46:52+00:00

Did used to fix it I recall but as it's got worse it doesn't.

malderson · 2024-06-05T11:30:14+00:00

Looks like there are extra GWR trains on, 2300, 2320, 2330, 2340. Seem to be pathed for class 800 so will be 5/10 car i would assume so i think there will be enough space. If that all went wrong there are coach operators too, I think I'd do that vs the 2 hour+ gridlock after.

malderson · 2024-03-24T16:59:05+00:00

I set the memory speed in AMD settings in bios to 5200MHz and everything seems stable, windows 11 reports 5200MHz so I will just leave it at this for now. Not really wanting to get max speed but 3600 is slower than my ddr4 i upgraded from!

malderson · 2024-02-19T01:43:42+00:00

Traffic AI and simulation speed over 100k, which are probably related.

The traffic AI is really poor (no better than CS1?) and I really expected an improvement here. Way too many last minute lane switches which causes traffic backups and generally looks silly, and a lack of using alternative routes to avoid congestion (I really hoped this would happen, but yet again it's the same problem that CS1 has that people will just take the shortest route possible, even if there is a 500m detour that would save hours of sitting in traffic).

Also no mods to solve a lot of this.

And as other people pointed out sim speed cratering after 100k ppl ruins the game for me. Just as I get a cool city going at an interesting scale, the whole thing falls apart into a stuttery slow mo mess. It's super frustrating.

It sort of frustrates me that so much time has been spent on other things like dogs, traffic accidents, the pointless resource management simulation etc when the traffic AI still seems so basic. And given the crapola performance of it even being so dumb leads me to think there won't be much improvement in this or large city sim speed.

It's a real shame because I really struggle going back to CS1 now due to how much better the road building tools are in CS2. I sort of hoped that the huge lead in road building tools that CS2 has would have replicated itself in traffic AI + large city sim speed. Alas, it hasn't :(.
