mjd··on 70k Books Found in Hidden Library in This Germany Home (2023)
But you nobody can read 70k books, so what was the point? He had a library nobody knew about, full of books he hadn't read.

That's not a library, it's an imitation of a library built by someone who doesn't understand what a library is for.

mjd··on Trump's global tariffs struck down by US Supreme Court
The filibuster isn't part of the system; it's not even part of the law. It's just part of the rules that the Senate chose for their own internal procedures.

mjd··on Coffee as a staining agent substitute in electron microscopy
I'm puzzled by this. Why hasn't there been, over the last fifty years, a huge amount of research into EM staining techniques and which materials were best under which circumstances? Edison supposedly tried 3000 different materials for light bulb filaments before settling on charred cotton thread. Why hasn't something similar been done in this area?

Or perhaps it _has_ been done and that's why nearly everyone uses uranyl acetate? And perhaps coffee was tried decades ago and found to be generally inferior?

It was a great theory, and I was glad to have read it. Thanks for posting!

Still not good, sorry.

Before I posted the comment I had tried looking at it in reverse video, very similar to your night mode. It was a little better, but not enough for me.

Update: it looks fine on my desktop computer. It's only illegible on my phone. Maybe use a heavier font?

mjd··on Sumerian Star Map Recorded the Impact of an Asteroid (2024)
There is something here that I do not understand. The article claims that

“[The tablet] is a copy of the night notebook of a Sumerian astronomer as he records the events in the sky before dawn on the 29 June 3123 BC”

But radiocarbon dating of trees buried in the landslide seems to have reliably dated the landslide to 7500 BC.

For example https://www.sciencedirect.com/science/article/abs/pii/S01695...

Update:

The Wikipedia article about the coauthor Mark Hempsell says:

“Hempsell got public audience as author of the book "A Sumerian Observation of the Köfels' Impact Event", with Alan Bond proposes a theory not accepted by the scientific community…”

The link posted in this thread by user arto calls the theory “pseudoscience”:

“Despite this new evidence, curiously in 2008 the impact hypothesis was revived by some pseudoscientists in connection to supposed observations of a meteorite by the Sumerians…”

Now it seems very suspicious that the article claims that the tablet is from 3123 BC, when it was excavated from the palace of Ashurbanipal (650 BC).

Even if you were right, your comment would have been a useless waste of time.

But the article appears to be a copy of a press release from the University of Bristol from 2008.

“In an American police procedural, we would either have…”

mjd··on Lite^3, a JSON-compatible zero-copy serialization format
“By default, deleted values are overwritten with NULL bytes (0x00). This is a safety feature since not doing so would leave 'deleted' entries intact inside the datastructure until they are overwritten by other values. If the user wishes to maximize performance at the cost of leaking deleted data, LITE3_ZERO_MEM_DELETED should be disabled.”

mjd··on Claude CLI deleted my home directory and wiped my Mac
That's the wrong question to ask.

The right question is whether I have made any important files world-writable.

And the answer is “I don't know.”

So, containers.

And I run it with a special user id.

No thanks, containers it is.

mjd··on Claude CLI deleted my home directory and wiped my Mac
Yes, although the example I had it operate on was different.
mjd··on Claude CLI deleted my home directory and wiped my Mac
A few months ago I noticed that even without `--dangerously-skip-permissions`, when Claude thought it was restricting itself to directory D, it was still happy to operate on file `D/../../../../etc/passwd`.

That was the last time I ran Claude Code outside of a Docker container.

The path taken did not traverse the boundary of every atom along the way, or even every grain of sand.

“The number of pageviews on your website and the number of likes on your tweets are fun to look at and sound impressive, but optimizing for them completely misses the point if they don’t lead to something more important (e.g. profit).”

Profit is fun to look at and sounds impressive, but optimizing for it completely misses the point if it doesn't lead to something more important (e.g. human flourishing, or net societal gain)

mjd··on Don't tug on that, you never know what it might be attached to (2016)
I had an interesting conversation with someone many years ago, possibly Brent Yorgey. We were thinking of arrays in quite different ways. To me, it was a data structure, with a specific memory layout: a contiguous block of memory containing a sequence of objects of all of the same size, specifically to support constant-time indexing. To him, it was an API, a mapping from non-negative numbers to values, and the underlying implementation could have been a hash table or whatever.

I think we're seeing a similar disconnect here. Some people think a string is a contiguous block of bytes, perhaps with a sentinel value on the end (C string) or a fixed-size count on the front. Others think of it as an API for storing text. These used to overlap, but in recent decades they have diverged substantially. The argument here is about the meaning of the word, not the technical reality of the thing it refers to, so it has no objective resolution.
