Knork-and-Fife··on Claude Opus 5.5 Intelligence, Performance and Price Analysis (Max)
The very first sentence:

> Claude Opus 5.5 is amongst the leading models in intelligence, but somewhat expensive when comparing to other models of similar price.

What does it mean for a group of similarly priced things to have one that's somewhat more expensive? Cost relative to cost means nothing. You'd think they are would talk about performance relative to cost.

Knork-and-Fife··on 9000 RPM is faster than your screen refreshes
It is awe-inspiring to think about the metal internals of a combustion engine moving so quickly because they're so heavy and complicated.

But in some ways it's more impressive to think about a $40 Dremel 4000 that can plug into a 120v electrical socket and spin at 35000 RPM

Knork-and-Fife··on Pebble Mega Update – July 2026
That is what they say in the article:

> most frequent are problems with the touch panel. At first, we thought this could be a hardware problem and replaced around 70 watches. After reviewing the units with our factory, we now believe this could be a software bug. We’re working to fix these issues with a software update - if we can’t, we’ll replace the affected watches (regardless of your warranty eligibility).

They also have to know where to look.

The big claim in general appears to be that the signal is not obvious because it averages out to normal background radiation noise. The article doesn't communicate this well though.

The bit that you quoted, I think that's just a random sentence that looks dumb out of context. I don't think it means anything special.

If the only loop is `repeat i in range(start, end, step)` , how do you do a loop like "Keep reading from a buffer until it's empty"? I.e. any loop when you can't know the number of iterations needed when the loop starts?
Knork-and-Fife··on From 400 Mbps to 1.7 Gbps: A WiFi 7 Debugging Journey
This is like asking why would anyone need more than a standard 110v North American electrical outlet in their home? Why would you ever install a higher capacity 220v socket somewhere?

Because it's a utility and there's a wide world of use cases out there.

For electrical maybe someone wants to charge an electric car fully overnight, or use a welder in their garage. Or use some big appliance in their kitchen.

For Internet maybe they make videos, games or other types of data-heavy content and need to be able to upload and download it.

Knork-and-Fife··on America is getting an AI gold rush instead of a factory boom
I agree with your assessment on the high end of China's development and the lack of awareness of that from people in the US. But I think the story on the low end /lower class is more interesting and I think there is lack of awareness there too.

Even within the US a lot of upper class people don't know what it's like for lower class people here. It's so easy to slip into homelessness because there aren't reasonable options available to many people to live anymore.

In China they still have a huge amount of their population in a developing stage so they still have ample tools and options and knowledge for how to maintain a reasonable life in a less developed state. So it's easier to fall back to a cheaper lifestyle, and culturally it's easier too.

But in the US were generations removed from these other ways of life, so there's no options or cultural acceptance of not living a highly developed way of life. So people just go straight from a nice house or apartment with modern stuff to being homeless with little to no tools to survive.

Just my probably naive thoughts. Would love to hear others takes on this.

Knork-and-Fife··on Budget Car Buyers Want Automakers to K.I.S.S
I think a lot of people do want these things, but car buying is not always up to just one person. It's often a decision made in the context of a family or group who will share a vehicle or otherwise have input on the buying decision.

These studies should be surveying these groups instead of individuals I think. Sometimes the "group" will just be one person, and that's okay. But I wouldn't want someone's opinion if they're making it on behalf of a group without the groups input, because that's not realistic

Knork-and-Fife··on Why doctors hate their computers (2018)
At my last doctor's appointment the nurse asked if I was okay with AI conversation transcription and summarizing that the doctor uses. So I had the option to decline.

I'm not sure how I feel about it yet. There are contextual details you might include when talking to your doctor that you wouldn't expect your doctor to write down into your medical record.

Knork-and-Fife··on I want an iPhone Mini-sized Android phone (2022)
I'm in a similar boat. I really (really!) wanted to love the jelly star (when I used it for almost a month), but on Verizon I didn't have an LTE signal most of the time in the Seattle area, including downtown, which I find unreasonable. Also the battery life was horrible, 20% per hour of active use and 4% per hour of standby.

Using the jelly star proved that using a small screen is not a problem for me and I would gladly pay money for an experience like that.

But it also proved that it is not an acceptable option in terms of quality. Hopefully the Jelly Max is better in these regards.

I think Jelly Max the ideal size for me too (jelly star was a little too small for doing driving navigation). I'll keep an ear out

Knork-and-Fife··on Spaced repetition systems have gotten better
I used basically this algorithm in college with the following setup:

Make a word document that lists all the keys to memorize vertically. Save as PDF

Open the PDF in a viewer with annotation tools. Make a clickable note in the margin just next to each key. Write out the value to memorize in the note field.

Cycle through the clickable notes. When you get one right easily, drag the note more to the left in the margin. As you cycle, focus on the ones furthest to the right. If you get one wrong, move it a bit further to the right.

In general the notes will move to the left until you're comfortable with all of them. And the balancing of which ones you need to see and focus on plays out very naturally and you feel in control the whole time.

There are many downsides with this compared to a tool like anki (e.g. I only used it on a laptop), but there was also something about it that just worked really well for me, so I never ended up switching to a different tool. But this was before anki had the similar algorithm described here. Maybe my experience would be different today

Small correction, pebbles use a TFT "e-paper" display, not e-ink. This is how they have reasonable refresh rates for animations and no after image problems. It's the best compromise imo
Knork-and-Fife··on Asus refunds Zenfone buyer for failing to provide bootloader unlock tools
A lot of the zenphone series had bootloader unlock as a listed feature which was then removed when they disabled and took down the tool. The Zenfone 10 was advertised as going to have the feature as well before and even after the launch for a bit. Asus claimed that the tool was coming at several points but the date in their promises kept getting pushed back and eventually turned into we don't know and now it appears to be never. This is stuff that was in writing from them, search it up, but you'll need to check the Internet archive for the info that they've removed from their own sites (like the repeated pushing and cancelling of the return of the unlock tool)
Knork-and-Fife··on Clean your codebase with basic information theory
> is it possible to create a bug because of something that's currently hidden from you?

Isn't this always the case?

I don't think there is a "full view" like you describe. Even if you're writing raw assembly, you're still working on top of the abstractions provided by the instruction set. There is no such thing as a full view where you can see every detail of everything that is going to happen.

I think the solution to this problem is tests and doing your due diligence in understanding what you're doing.

Having more control over what abstractions you're seeing should help with the understanding part, which should in turn reduce bugs resulting from lack of understanding.

Edit: related thought: it's about improving the tooling. Which I suppose is another thing for someone to learn and possibly misuse. But I don't think it's correct to say that firefighters shouldn't carry axes because they could accidentally kill someone with them.
