tensility··on Anger over Data Centers Is Fueling a New Political Movementtca
What if I hope for a genie to emerge from a lamp in order to grant me wishes?
tensility··on TSON – A JSON superset with immutable, hash-pinned schemas
Okay, but does it support comments?
tensility··on CarPlay Is Additive
Agreed. Lack of CarPlay support is just one of the reasons that I won't own a Tesla. (Also, I prefer not to support anything tainted by Elmo's toxicity.)
tensility··on CarPlay Is Additive
Agreed. CarPlay support is table stakes fo me fir my next vehicle, no matter how good its native UI is.
tensility··on AWS Bedrock to require sharing data with Anthropic for Mythos and future models
Trying to figure out whether this statement was intended as sarcasm or if it's willfully blind to decades of rising surveillance capitalism as business model.
tensility··on How to earn a billion dollars
The only reason it doesn't is the greed of folks who become billionaires.
tensility··on How to earn a billion dollars
This...100%
tensility··on How to earn a billion dollars
Guillotines are the classic method, and they are likely coming if we don't change course.
tensility··on How to earn a billion dollars
Well, with the extreme levels of income stratification that we have in the US and greater world, money literally means a different thing to the few folks who've escaped the poverty trap ... just like hunting means a different thing for the hunters as it does for the prey.
tensility··on Did Anthropic ask for this?
It's all interesting advertising / news; however, why does it have to constantly cost me five precious vertical lines of text worth of screen real estate in Claude Code that apparently can't be dismissed? FFS

Certificate expiration timeline...
tensility··on Show HN: I Made a Programming Language with Python Syntax, zero-copy and C-Speed
Cool. Now go check out Mojo.
tensility··on Can a Computer Science Student Be Taught to Design Hardware?
SICP should probably be required reading in the CS curriculum. It's a great start at understanding register hardware simulation.
tensility··on My iPhone 16 Pro Max produces garbage output when running MLX LLMs
Yeah, that was not at all my experience in CoreOS/SWE, where we would sometimes/often have to wait weeks for submissions to turn around in B&I to become part of "daily" builds. Glad you don't have to put up with the same ridiculous crap process.
tensility··on My iPhone 16 Pro Max produces garbage output when running MLX LLMs
A statement which goes to show that confusing correlation with causation is all you need.
tensility··on My iPhone 16 Pro Max produces garbage output when running MLX LLMs
The fixing of a bug at Apple is the easy and quick part. It's the submission process from then until it gets released as part of an OS update that is the ridiculously long (and too often difficult) part.
tensility··on My iPhone 16 Pro Max produces garbage output when running MLX LLMs
It would have to be a very serious security bug. Even then, unless they've totally upended their software development workflows in the past couple of years, the Apple I knew extremely well from the inside couldn't turn around a software fix this quickly, from PR to OS release, even if its existence depended on it. There's simply too much bureaucracy and process around submitting anything, no matter how vital.
tensility··on Floppinux – An Embedded Linux on a Single Floppy, 2025 Edition
At a very low level, it is. I know the individual that made a "diagnostic" for the floppy drive while working as a tech on the Apple I and Apple II designs which caused the drive to whine in patterns that were distinctly ... orgasmic.
tensility··on Floppinux – An Embedded Linux on a Single Floppy, 2025 Edition
If I recall correctly, when you wanted all of the bells and whistles that Slackware had to offer, it required 72 floppy disks.
tensility··on Floppinux – An Embedded Linux on a Single Floppy, 2025 Edition
Bring back Slackware?
tensility··on Ask HN: Is it still worth pursuing a software startup?
The fruit company still has an internal culture, especially in hardware-focused teams, with a relentless focus on shipping products followed by iterative refinement.
tensility··on PCs refuse to shut down after Microsoft patch
So, should we assume that they vibe-coded this patch? Sad...
tensility··on Re: Mix: open-source repairable blender
Meanwhile, I've had the same blender for thirty years, and it's still going strong.
tensility··on The struggle of resizing windows on macOS Tahoe
I would love to go back to more skeumorphic system interfaces. The layered panes of glass metaphor has been a pain in the ass from a usability perspective from the get go, enough so that I cheered to hear of Alan Dye leaving Apple.
tensility··on An Honest Review of Go (2025)
One of the few languages I've known that didn't provide any standard features for libraries (until the sixth major revision), Scheme, has been the worse for it.
tensility··on Twelve Days of Shell
Not giving real output is a complete fail. Try again.
tensility··on Unpowered SSDs slowly lose data
This.
tensility··on Unpowered SSDs slowly lose data
Oh, it would be nice if it were just feature size. Over the prior 15 years, the nand industry has doubled its logical density three times over with the trick of encoding more than one bit per physical voltage well, making the error bounds on leaking wells tighter and tighter and amplifying the bit rot impact, in number of ECC corrections consumed, per leaked voltage well.
tensility··on Unpowered SSDs slowly lose data
At the physical device layer (i.e. what a nand controller vendor programs to), a nand flash device that supports ONFI 2 SLC Mode can be configured to use (some of) its blocks in SLC mode rather than MLC/TLC/QLC/etc. This allows one to divide the array into high-reliability versus high-capacity regions.
tensility··on Unpowered SSDs slowly lose data
There are also expensive high-grade SLC NAND flash chips available that offer significantly higher retention time than the cheaper commodity channel TLC NAND (i.e. 10 years versus 3 years).

In general, though, whether NAND or NOR, the fundamental way that flash works is by creating an isolated voltage charge for each bit (or several bits, for TLC), making it effectively a vast grid of very tiny batteries.

Like all batteries, no matter how well-stored, they will eventually leak energy to the point where the voltage levels change enough to matter.

Further, it's not enough to simply make power available to this grid since the refresh of the cells requires active management by a nand controller chip and its associated software stack.
