Higher homotopy groups of spheres goes way back to the 30s. This isn't lazy writing. https://en.m.wikipedia.org/wiki/Homotopy_groups_of_spheres

Looking at all the continuous functions from all dimensions of spheres into a particular topological space ends up giving rich algebraic information about the space. This is a cornerstone of algebraic topology. Turns out calculating this stuff for even just spheres can be subtle and mysterious.

Uniform distance matters not at all for any of this, but it does matter that your family of "spheres" be topologically equivalent to the round spheres.

Another model is you take the iterated suspensions starting with a pair of points (the zero sphere).

Yet another is to take boundaries of simplicies, or even cubes.

Topologists are those who are perfectly happy to call a paper towel tube an annulus.
Japanese is notorious for not having a fixed set of pronouns, and in many cases people just refer to each other (and to themselves) by their proper names.
Definitely broken for me on Excel version 2302 (build 16130.20714) on an En/US locale.

None of the ISO8601 formats I've tried are recognized. "2023-08-22", "2023-08-22T01:38:22Z", "20230822T013822Z" are all valid ISO8601, but Excel treats them as unformatted text. Inputs with slashes are instantly recognized as a date.

If it works for you, it may be a locale thing. But getting away from that is the whole point of ISO8601.
The phrase shouldn't have triggered sanction alarms as the words in the domain are common and no acronyms. Although anything is possible.
It's far too late for that. Over 10 billion RISC-V chips are already in use in GPUs, hard drives, automobiles, and so on. Uncountable person-hours have been put into adding RISC-V support to Linux, Android, Chromium, GCC, and thousands of other libraries and software packages.

Google, Qualcomm, Intel, IBM, Samsung, and nVidia are among[0] the RISC-V organization's many members, who have already collectively invested billions of dollars in the technology. At this point, telling the tech industry to stop using RISC-V would be like telling them to stop using Linux.

Surely the difference is that F1 is a sport, and Monster Trucks are entertainment ? Not better, just different.

If you go to watch the Harlem Globetrotters you're getting a very different experience from a good NBA game, but that's not because one of them is doing it better, they set out to be different things.

Or wrestling (the martial art) versus Professional wrestling (a theatrical performance). Like yeah, I guess it is more entertaining when an angry wrestler smashes a chair over the Owner's head, but they practised that over and over, they used a chosen chair. If he later "wins" the fight it was scripted, they decided on that outcome up front and maybe the "loser" got a Hollywood gig so he's being written out soon anyway. Whereas the guy who got Olympic wrestling gold was really fighting those other guys - under some strict rules it's true, but there was no script, if they were better they'd have beaten him and they'd have the medal.
Let me rephrase it so the meaning of what you just said impregnate my mind: you were denier money because their records showed you badly needed it. Sound to me the credit agencies aren't the only evil.

As I understand it, taking a snapshot with ZFS involves writing a metadata object and some data references. Assuming 100 GB of data, 128K block size, and 64 bit pointers, I'd guesstimate * that new data written during a snapshot would be in the ballpark of 5 MB. Is doing that 6 times per hour (52,560 times per year) enough to cause premature wear on the drive? That would be ~256 GB per year. This is likely under 1% of an SSD's write endurance. So, I'd be surprised if taking 10 minute snapshots was a significant causal factor.

* I could be wrong, I asked for some help from not the most reliable sources. Happy to be corrected. Still, if my estimate is higher than actual and yet still unlikely to affect drive longevity, it may be moot.

I've reflected similarly after this exercise.

I've lost data before, but it felt terrible to lose my context and working memory. While I make sure the most important stuff is in git, there's a bunch of momentum and working memory in my bash history and system configuration. It's also nice to not have to think very hard about a patchwork of backup plans.

It's nice to get a fresh start every now and then, but not under duress. I was in the middle of a multi day project and was gonna lose time either way. It was real nice to boot back into a machine that felt like home.

> it's most people most of the time

it absolutely is most people most of the time. just ponder how many advice columns and platitudinous commencement speeches and gurus and old cranky uncles and pretentious 8th grade teachers (and etc etc etc) there are. hell think of the likelihood of getting XYed in our very own industry.

> folks advise others to do the thing(s) that they _did_ do.

the meat of the point isn't that people exaggerate. even giving people the benefit of the doubt, that they don't exaggerate, they're giving you advice that's 99% of the time non-transferrable, i.e., completely useless for you and serving only the purpose of enabling them to take a nice trip down memory lane. if i'm asking someone for advice, that's an expert, i'm not asking them what worked for them in the instance of the problem they face; i'm asking them about my instance. and it is a very rare person that knows you well enough and takes the time and care and effort to advise someone individually and/or germainely.

I don't think of New York specifically or Jews at all when I see the term "coastal elites."

I think of wealthy business owners on the east and west coasts. Venture capitalists. Managers at software companies. Politicians. Just high paid and/or influential people who think highly of themselves and others in their cliques.
I got very lucky:

- Decided there was no future at my then current job in June

- Applied to a handful of places with no response

- Followed up with a recruiter who had been pinging me for a year. Turned out I was a great fit (aligned experience in math, data engineering, fintech), 3 rounds of interviews, accepted job offer in early July

Would probably still be looking if the stars hadn't aligned (new job is great so far)
Much of it (LLVM) is open source, and for the rest I don't think understanding the inputs and outputs is actually that closely related to being able to maintain the bits in the middle, or come up with new bits.

The consent referred to by the other commenter is entirely fabricated and false. I challenge anyone within the US to show the contract giving the current administration explicit consent to govern us.

This level of narrative and dogmatic belief is how governments gain influence. They're simply the local bullies. If you need proof, look at how much they put into caring about struggling people. I.e. next to nothing. Our country betrays us daily and has the gall to demand obedience. We are not dogs.

This may not be the best title, it's the desired function of the add-on to generate noise and making tracking and targeting less useful. There is nothing hidden about what it is doing for the user.
There's a difference between a shortcut that has the interest of the firm in mind. And sabotage. I'm always surprised how little sabotage is recognized / repressed in corporations. Certainly there is the issue of recognizing the one from the other.

But still sabotage seems to be frequent - as part of "empire building", as part of gaming the compensation metrics. And "boys will be boys" is not the a response that steers toward the desired behavior.
Mostly different in terms of performance and wear on the drives. If you rsync over and over, it has to scan basically the whole filesystem for changes each time. Zfs snapshots don't. The snapshot is ~instant and the calculation of what to send has no need to examine any files.

I don't think the performance and drive-lifetime hit of running rsync every 10 minutes would be good.

Zfs should have an edge in terms of atomicity as well, but in practice I'm not sure how much that matters. I _think_ it does matter but isn't perfect (zfs can't trick applications into doing atomic writes if they're not already, but it won't have _another_ worse layer of breaking atomicity like rsync must).

Manifest v3 extensions have access to DOM via the content script (same as Manifest v2). Why would they not do cosmetic filtering? Is that something uBlock Origin developers announced?
It's on my list, but... to be honest if you Google "separate header Luks", you'll find it's trivial to create a LUKS device with a detached header. Then the default ZRepl quick start will get you going with the basic pool-to-pool local replication. That will get you almost all the way there. :) I used their docs/guide to do the remote replication too, though it would make a good write-up as I could throw in how I use sops-nix for securing the Zrepl TLS bits for the remote scenario too...
It is of great comfort to learn that lazy writing did not exist in 1930. And no mathematician would have ever misrepresented his work to the public back then. They wore top hats then. Far too proper to stoop to lowly deception to achieve recognition.

LOL nevermind—I was right the first time. Thank you for confirming.
Out of my international circle of friends between twenty five and forty, only one outright owns their own house. And they have a high paying internal software development job for a big European company. The rest of us either split rent or live with family. Those of us in said circle living in the U.S. will likely never own houses because of what ChrismarshallNY below stated: The few places that aren't McMansions and aren't in HOA developments and thus are actually affordable are being bought by massive investment firms and flipped into being duplexes for rental.

Even the trailer parks aren't safe, as the companies buy them from the owners, evict all the tenants living in their own houses, and then develop the land into more unaffordable HOA clone mega houses, luxury apartments, or McMansions. Near where I live six of the eight trailer parks have disappeared in the last four years and have been turned into two separate campgrounds, a car wash, a dirt parking lot waiting to be redeveloped, a warehouse, and a new luxury senior apartment complex, with intent to redevelop the others into retail or housing shortly. There's been a spike in homelessness because the people living in these trailer homes couldn't afford to move their houses and didn't have anywhere left to go even if they could.
I agree with the sibling; the problem is that requires that you shoehorn all your rich data types to JSON.
I agree that it was unlikely. The total size of all data and snapshots was 625 GiB on a 2 TB drive (which had seen less than 2 years of moderate use). It was a pretty unexpected failure.

Ask HN: Nicknames for Computer Science Books?
Hi HN,

From that scene in Hackers where they were listing off books with nicknames (ex. Compiler: Principles, Techniques and Tools, aka "The Dragon Book," I ended up being curious about what other books might also have the same treatment. This is the current list I have, scoured from places like Wikipedia, Amazon and other forums, but I wondered if anyone found anything else? (This is just for my own curiosity)

The AWK Programming Language, Alfred Aho, Peter Weinberger, Brian Kernighan, aka "The Gray Book"

The C Programming Language, Brian Kernighan and Dennis Ritchie, aka "The White Book"

Compilers: Principles, Techniques and Tools, aka "The Red/Purple Dragon Book"

Computer Architecture: A Quantitative Approach, aka "The Pillar Book"

The Design and Implementation of the FreeBSD Operating System, aka "The Devil Book"

Foundations of Computer Science, Aho, Alfred and Ullman, Jeffrey, aka "The Turtle Book"

Introduction to Automata Theory, aka "The Cinderella Book"

Lions' Commentary on UNIX, 6th Edition, aka "The Lions Book"

Modern Compiler Implementation in ML, aka "The Tiger Book"

Operating Systems: Three Easy Pieces, aka "The Comet Book"

The OpenGL Programming Guide, aka "The Red Book"

The Peter Norton Programmer's Guide to the IBM PC, aka "The Pink Shirt Book"

Principles of Compiler Design, aka "The Green Dragon Book"

Programming Perl, aka "The Camel Book"

Programming Ruby, aka "The Pickaxe Book"

Unix Power Tools, aka "The Unix Book"
I know I left another comment, but I'm replying in a new one to increase the chance that you'll see this: It would probably be very useful to a lot of people if you (or someone) made a standalone library out of this. It looks like Shelby requires Pinecone, but using something like ChromaDB for local embeddings and providing a library that I can just import, add documents to, and then query for answers would enable all kinds of applications.

I'm currently trying to build a hobby virtual assistant, and it looks like RAG does need some nuance to implement correctly (from what you said). A library that does all of what you mentioned would take a lot of work out of it.
I did a slight edit now, hope that makes it more clear.
Would keeping the camera on help? When it is on, the stabiliser components are active and they should counteract most of the vibrations. If this works, it might be worth it for apple to detect motorcycle vibrations for more than x minutes and energise the stabilisers without actually turning on the other imaging related parts of the camera.
The pi supposedly can get FS corruption, but I've never seen it because every time I install an image, I run a script that puts tmpfses everywhere and turns off mostly useless logging. Those things just run for ever, very reliably, as long as you don't hammer the SD card.

ZFS looks so cool! Unfortunately when I eventually get a NAS I doubt I'll want to pay for anything that can run it, so I suspect I'll just be doing RAID and ext4.

I always stayed away from BTRFS, because every few months I'd see a "BTRFS destroyed my data" post, followed by an argument about if it was BTRFSes fault. I see them less now, perhaps it's time to revisit?

Unfortunately, as a tab hoarder myself, I had to remove Tree Style Tabs when I figured out it was the single reason Firefox was taking about 1 second after clicking to do actions like open a new tab or switch tab, and generally higher than ideal CPU usage. When I disabled it, everything got so much faster, it was like getting a new browser.

So I switched to Sidebery, which seemed much faster at first and I still have it enabled sometimes. But after a while and many tests to be sure, I found Sidebery was the single reason Firefox was taking an extra 10GB or more RAM. Just today, I opened about ten Hacker News tabs for an afternoon's read, and the RAM usage crept up from 18GB to 28GB. These are text-only sites as you know, and like most people I didn't read the articles only the HN comments :-) So that's a lot of unexplained RAM. I disabled Sidebery in that window and the memory usage crept back down to 18GB. (If I launch Telegam in a Firefox window with Sidebery enabled it goes up to 67GB then crashes as my SSD is too full for that much swap!). If Sidebery is disabled all along, the memory usage doesn't creep up like that.

These are figures reported by iStat Menus on macOS on my laptop. The swapping induced by the higher RAM usage caused scrolling to be extremely janky, as well as editing in forms and text boxes.

So unfortunately for me, to have a reasonable browsing experience, I found I can't use either of the good tab-sidebar extensions Tree Style Tabs or Sidebery with Firefox at the moment, each for a different reason.

I haven't seen other people reporting these issues, and each one took me a while to recognise. Therefore I asume these issues are related in some way to the total numbe of tabs and/or windows I have and that most people aren't affected (enough to matter), or those affected haven't found the cause.

There are some tab group extensions, but I found Simple Tab Groups lost hundreds of my tabs several times, with no indication that it had lost them (they just weren't there when I went to find them later), so I stopped using it.
I’ve had some interesting results using GPT4 to generate mermaid diagrams from descriptions of my architecture or processes.

Plus, the output being code, it’s easy to fine tune when the inevitable mistake creeps in every once in a while.

It’s funny. I have never documented anything so thoroughly. It was just too time-consuming. Now I do. In part because I know there will be a diagram to complement it and improve the likelihood any of it will prove useful to someone at some point.

But also because keeping said documentation and diagrams up to date will be easier.

It gives them money in the short term but it costs their clients money and makes the service overall less valuable. If everyone installed this it would basically wreck the online ads industry overnight.
there are so many things that should have killed the industry by now, but it finds a way to keep thriving ...
It gives the networks money but it also hurts the companies actually running the ads, which would disincentivize them to do it at all, and the networks will only make more money if companies don't see a decrease in pay off for clicks and reduce their offers/stop running ads through that service altogether.

That being said realistically this is too niche for nearly enough people to run it to make any significant difference on the scale of the networks themselves, it'll just obfuscate your tracking a little.
