I read the Dbos vs Temporal thing, but can you speak more about if there is a different in durability guarantees?


The durability guarantees are similar--each workflow step is checkpointed, so if a workflow fails, it can recover from the last completed step.

The big difference, like that blog post (https://www.dbos.dev/blog/durable-execution-coding-compariso...) describes, is the operational model. DBOS is a library you can install into your app, whereas Temporal et al. require you to rearchitect your app to run on their workers and external orchestrator.


This makes sense, but I wonder if there’s a place for DBOS, then, for each language?

For example, a Rust library. Am I missing how a go library is useful for non-go applications?


There are DBOS libraries in multiple languages--Python, TS, and Go so far with Java coming soon: https://github.com/dbos-inc

No Rust yet, but we'll see!


This from quantizing their Gemini model?

There are a lot of anecdotal reports of quality differences following some Gemini 2.5 Pro releases earlier in the year.


I for one think that Gemini 2.5 pro has become much more stupid than before. This isn’t for coding, just simple business type support. It keeps forgetting queries, making really obviously bad suggestions, simple mistakes etc etc.

It’s kind of funny, because they keep talking about how close we are to AGI, and in reality they keep making the models dumber (uh, I mean more efficient).

Gary Marcus tends to have pretty shallow analysis or points.

His takes often remind me of Jim Cramer’s stock analysis — to the point I’d be willing to bet on the side of a “reverse Gary Marcus”.


You'd take the other side of a reverse Gary Marcus? So you'd take Gary Marcus' side?


Fixed, thanks.



Hilarious. It’s impossible to have an original thought!


Hinton on Marcus is quite funny too https://www.youtube.com/watch?v=d7ltNiRrDHQ


ChatGPT 5> Without adding third-party dependencies, how can I compress a Data stream with zstd in Swift on an iPhone?

(It auto-routed to its thinking model, took 25s)

> Short answer: you can’t. iOS doesn’t ship a public zstd encoder/decoder. The system Compression and AppleArchive frameworks only expose lzfse, lz4, zlib/deflate, and lzma. So with only Apple SDKs, there’s no way to produce zstd-compressed bytes.

> > Two practical paths:

> 1. If zstd isn’t mandatory, use a built-in codec (lzfse or lz4 are fastest) via Compression’s streaming API. Example (pure Swift, no deps) that compresses an arbitrary byte stream: >

> <code example>

> 2. If zstd is mandatory, you must embed zstd yourself. That can mean:

> - Vendoring the official C sources (libzstd) directly into your project and calling them via a tiny Swift wrapper/bridging header

> - Statically linking a prebuilt libzstd.a you compile for iOS


Here's what I got with ChatGPT GPT-5, it must not have thought about it because it was near instantaneous:

>On iOS, you can use Apple’s built-in Zstandard (zstd) compression API from the Compression framework — no third-party dependencies required.

Looks like that time it didn't route to the thinking model. The router mechanism is deeply confusing right now: https://twitter.com/emollick/status/1954210778321465634


I think the useful takeaway here is that Top 1 operation is generally not a good idea, especially not for making judgements. This doesn't address the main points of the blog though.


This is why this stuff is going to shift to the user’s AI enabled browser.

Half of the sites already block OpemAI. But if it is steering the user’s browser itself?


The commentary around every Chinese model is incredibly disappointing. Asking about Tiananmen Square isn't some clever insight.

Look at the political leanings that government-backed AIs in the United States will soon be required to reflect: those of the current administration.

I was hoping to hear from people reporting on their utility or coding capabilities instead.


It is especially stupid because there is nothing analogous to Tiananmen Square in the west.

On the other hand, have it write a dirty joke. It just wrote me a few jokes that silicon value wouldn't touch with a 10 foot pole.

Not sure about the utility overall though. The chain of thought seems incredibly slow on things that Sonnet would have done in a few seconds from my limited testing.


Actually there is, fire up OpenAI or Claude and ask it for crime statistics.

I did and it lectured me on why it was inappropriate to ask such a wrongthink question. At least the Chinese models will politely refuse instead of gaslighting the user.


I just did and it gave them to me. What did you write in your prompt?


No, you've got it wrong. If US models are suddenly required to praise their monarch, or hide his past affiliations or whatever, that warrants them more critique.

Chinese models aren't don't become exempt "because the US is also bad", they both rightfully become targets of criticism.

Other than that, testing the boundaries of the model with a well-established case is very common when evaluating models, and not only with regards to censorship.


Agreed.


Have CC output a plan.md file.


Remote tracking?


Just a simple radio transmitter could fulfil that function.


At the cost of it being really obvious where you are.

However the bigger draw is probably high bandwidth two way communication globally. No need for an obvious route as you can use GPS to get near US waters before turning it on, while still being in control of location of delivery or even meet up with it on the open ocean.


Not as obvious as a Starlink transmitter though!

Sending the position only requires a few bits, let's say 48. A position update requires even less, depending on how far it could have travelled since the last known position. At such low data rates you could hide the transmission quite effectively.


As a once off it’s not going to be investigated, start making regular trips and people are going to start looking for such signals. Short bursts strong enough to detected many hundreds of miles away inherently need to be fairly strong making them standout from the background noise for close receivers. You can similarly triangulate based on signal strength given some ocean ships or even cheap buoys.

Starlink needs to be detectable by satellites, but you can almost completely block the signal going in other directions.

SpaceX might already be sharing it’s data with coastguards though.


I also wonder if you could have a visible surface vessel (e.g. fishing boat) which acts as a navigation beacon for the sub. Sub can just follow the beacon without any active communication of its own. If enforcement appears, sub will destructively sink to avoid revealing the operation.


No. Consider the distances.


Does the AI have the same content restrictions that the chat service does?


Yes by default, but you can change it:

> Additionally, developers can also control moderation sensitivity with the `moderation` parameter, which can be set to auto (default) for standard filtering, or low for less restrictive filtering.

I played around with this last night and although it still sometimes refused to create images, it seemed to be significantly more lenient.
