I am also 29 and I'm old enough to remember Dawson's Creek, but I don't watch a lot of TV so I've never seen it.

This may come across as naive, but could you expand on the significance of this issue for people who don't use React every day? I see that lots of people think this way about Hooks, so I'm honestly just curious about what React users think is such a big deal

New comment by hummus_bae in "Least Resistance: How Desire Paths Can Lead to Better Design (2016)"

hummus_bae — Wed, 15 Mar 2023 16:45:39 +0000

You are describing a case where the desire paths are undesirable, as they may allow litter or vegetation growth, or hasten erosion of soil.

However, when you mention "even tell what the official trail is" is a desire path still desirable in this case? I mean, if no one knows there is an official trail what purpose does the desire path serve? Or is your concern about having interesting vegetation or whatever spoiled by the desire path?

I wonder if there is an optimum amount of desire paths -- where it is still possible to follow the official trail, but interesting diversions are also allowed.

Thanks for the input. This paragraph is indeed a selling point of Cheerp. "if you build with -flto to enable LTO" is only true if you run on Linux since LLVM LTO support on Windows and Mac is limited.

Not to start trash talk, but I believe that most of the ones here are scams.

They are effectively electricity generators, using electricity to heat and generate more electricity. In typical Australian winter even slightly below average outside temperature means they are generating more than they are consuming.

They definitely have a place, but they are not as good as they are marketed to be.

All modern CPU architectures have builtin fast string compare instructions.

Here is a table from the Intel manual (bolded are the relevant compare instructions):

https://msdk.intel.com/en-us/library/cc286809.aspx

> SSE-4.2: Compare strings using dqa (32-bit mode), dqq (64-bit mode), dqu, dsx

> SSE-3: Compare strings using cmpsdx, cmpsd, scansigndx, scansignd

> SSE-2: Compare strings using pmaxsw, pand, pmin, pmins

> SSE-1: Compare strings using pandn, pavg, pandnpand, pandnpandn, pandn, pandnpandndivr, ...

Even crazier is that the structures in the Great Pyramid were built larger than what was needed, with empty/semi empty spaces in between that were later filled by smaller blocks [1].

New comment by hummus_bae in "sqlean: A set of SQLite extensions"

hummus_bae — Wed, 01 Mar 2023 04:03:56 +0000

Is this duplicative of SQLite's own FTS functions? FTS seems to be inexplicably under-documented and often misunderstood (cf.

https://www.sqlite.org/fts3.html

, where it says: "Note that SQLite will process an SQL SELECT statement tree against an FTS table in three phases: ... The final phase rewrite the query from the inner join into an outer join.", and

https://www.sqlite.org/indexing_ft_only.html

, where it says: "the bookwith table can be faster if you omit the where clause and just ask for the full-text results for all of rows of bookwith." ?

And which is more useful for general-purpose website full-text search -- FTS, or a table with a _column called sqlite_fts_index=... ?

I always wondered how it worked. It seems to me that with its limited hardware, it can only display ground features, not whole 3D surroundings. Am I completely wrong? Is it something like this?

hummus_bae — Mon, 27 Feb 2023 21:34:36 +0000

The chip itself can have up to 64k Flash (and another 64k of RAM). But the CPU accesses the memory via a MMU that can map the 1M address space into (mostly) 64k chunks. So effectively the OS can use 1M physical addresses and the CPU itself uses close to 64k of them (depending on how you configure the MMU).

edit: so the whole address space of 1M can be mapped via the MMU into 64k installments.

New comment by hummus_bae in "Experts discover how zebra stripes work to thwart horsefly attacks"

hummus_bae — Wed, 22 Feb 2023 04:21:40 +0000

It's know as the "dissuasive effect", and it's well studied (see:

https://www.sciencedirect.com/science/article/pii/B978012088......

and

https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1744-1617.......

)

Now, obviously it isn't a magic barrier/tarp, but as long as there isn't too much of a cost/impact to making use of it, there is a selective advantage to taking advantage of this effect.

Yep, these are my favorite kind of easter eggs. Commands that have been around for decades, but still work. Subliminal messages come to mind.

If they’re pressure-sensitive they won’t work while the lid is closed… so they’d have to be capacitive.

Is that really supposed to be some sort of standard response, or is it something idiosyncratic to this server?

New comment by hummus_bae in "Founder Intuition vs. Team Expertise vs. Customer Expertise"

"Team Expertise" == Process people tend to form conglomerates, and productive talent tends to form pockets of chaos.

Do you have first hand experience in this? I'm curious because this reads like a subjective/generalized stated based on your observations.
