I just bought a Quantum Superloader3 last Xmas. Each LTO-8 tape (it can take 16 in 2 magazines, I use 15 + 1 cleaning tape) will hold 12 TB without compression, 30TB with, and 7 of them can back up the 100TB used on the 128TB of disk that is the house RAID array.

It takes about 2 days to make a full backup, and I can fit incrementals for the next 5 days on the batch-of-7. Then I switch to the second magazine, and do the same thing. I actually have 3 magazines, one of which I swap in and out every week, and during the before-times, I'd take that off-site to work.

I have ~30 years of data, from back when I was in college and writing CD-ROMs for backup, all on the one system. Admittedly, the major space-taking thing is the Plex library, but I wouldn't want to lose that either. It takes about 5 minutes to walk into the garage (where the server-rack is), swap magazines and I'm done - the rest is automatic.

I have vague ideas for writing a more-efficient tar designed for this specific type of setup (big disk with attached tape). The best way to do it I think is to have multiple threads reading and bzip2-compressing data, piping blobs through to a singleton tape-writer thread. Every now and then (50GB, 500GB, 1TB ?) close the device and reopen the non-rewindable device to get a record-marker on the tape, and then store the tape/record-marker/byte-offset etc. into a SQLite database on the disk. That way I'd get:

- High levels of compression without making the tape head wait for the data, which ruins the tape head. Multiple threads pooling highly-compressed data into a "record"

- fast lookup of what is where, I'm thinking a SQL LIKE query syntax for search, against the disk-based DB. No more waiting for the record to page in from the end of the tape.

- fast find on-tape, since you'd know to just do the equivalent of 'mt fsf N' before you actually have to start reading data

Right now, tar is good enough. One of these days when I get time, I'll write 'bar' (Backup And Restore :)
I think one should run simulations of MOND first; MOND does not directly make a statement about rotational structures; it makes a statement about the gravity law. This galaxy clearly has unique structural considerations that could yield results that you don't expect from a trivial glance at higher order factors.

Edit, after digging: someone has, apparently.

https://www.researchgate.net/publication/336982682_A_new_for...

I can't speak to whether or not the paper is any good, but my quick understanding is that: the galaxy is consistent with MOND if the distance to the galaxy has been misestimated; at least one published estimate (that disagrees with most estimations) of how far it is to 1052 falls inside the range where it's explainable by mond. My (limited; I last took astro a very long time ago) understanding is that how we measure distances to foreign galaxies (slam-dunk methods like cepheids don't work if there are no cepheids) could be very sketchy for galaxies of different structures. Here is part of the ongoing debate about distance. Linked is a paper from the perspective that would disfavor MOND (the Trujillo estimate is what needs to be true for 1052 to be consistent with MOND according to the first paper):

Hi Andrew,
A bit different from usual HN fare, but here's a quick nerdy breakdown of how to build power / advocate / get laws changed.

You have an audacious, but specific goal. That's great!

You have at least one person who cares about the outcome of your campaign (you). That's good, you'll need more

1. You need a power map.
https://commonslibrary.org/power-mapping/ is a good resource to get you started. Get together some mates, preferably ones who've interacted with the political process before (They'll be more likely to know the players) and start mapping.
Once you've got a good power map, that's a good time to reflect: Does this campaign still seem achievable? Is there too much power in the top-left quadrant, and not enough in the top right / middle?
Movements that lack a good 'center' of persuadable+influential actors generally fizzle out, so you might want to consider tailoring your campaign goal.

2. You need a theory of change. How do we get from here to there?
https://www.thechangeagency.org/?s=theory+of+change is a good start. Don't lock in to a particular tactic too readily, and be prepared to iterate

3. You need power. This both informs and influences your theory of change. Is your power electoral, financial, social?

4. You need a logframe.
https://en.m.wikipedia.org/wiki/Logical_framework_approach
How will you know if your campaign is working? What intermediate metrics of success can you identify that are both impactful and measurable?

There's a mountain of campaign theory and literature to read, but that's enough to get you started assessing if your campaign is a goer at all. Hope it helps
Fair enough, that'll just be a necessary evil at least until market/ownership restrictions land in the online video space. There's plenty of uncompetitive Amazon behaviors even without that.

Hardware companies are seldom good at software. The ones that are really stand out.
They're tapes with encrypted data, and they're $20 each. You can write many copies, check the hash, and distribute them in many places.

Put them in safety deposit boxes at the bank, give copies to a friend, bury them in your backyard, and - yes - store a set or two in the closet.

Because they're encrypted, there is the issue of the encryption key needing to be managed. But that's the only issue.

I assume these are references to Isaac Asimov’s Foundation.
This question determines if you need to be DRY or not:

"If [some fact] in the code base needs to change, how many places would we have to change it in?"

If the answer is > 1, you have a very good DRY case. Otherwise, when [some fact] changes, it will probably not be changed in one of the places, and the system will be broken.

This often coincides with having an "elegant codebase", but that's not the most important part.
Just because it's on the internet it doesn't mean it's true.

You might be confused how a CPU, memory, and I/O are interconnected. First, for an application to access data in memory, all it need to do is issue a MOV with indirect addressing. It might trigger a minor page fault which gets handled quickly by the OS. For an application to read data from disk, it must submit a request to the disk controller through the OS. I am ignoring a lot of details but that's all you need to reconsider the information in the links you shared.

Keep in mind that reading from memory is in the nanoseconds, while reading from NVME is in microseconds.
Yep...the excitement of spending hours exploring, followed by the dismay of having to work off a multi-hundred dollar phone bill.
OP title said "general inheritance is bad", not " Generally, inheritance is bad".

And the text support that. The "general inheritance" the author describe is not the one you've just used.

And i'm hijacking your post, sorry, but i really agree with the author with the "incidental inheritance" point. This is the worst. I lost a month to a bug caused by this kind of inheritance (Jenkins package that tried to be cute and interfered with a cloudbees class). I won't take a java gig ever again. Not worth the brain damage.

Doesn't matter if you call this stuff "recommendation engine" or "editorial decisions", it is still censorship by definition. This is the newspeak George Carlin had a relatively known take on.

Stop calling the censorship "editorial decisions". We are not debating the "editorial decisions" part, we are debating the censorship part.
I feel like it's a very useful metaphor for the work ahead in dealing with energy production, consumption, storage, efficiency, etc.

Layer 1: We must think of clever solutions to reduce our energy footprint where possible and shifting typical energy uses around is one way to do so

Layer 2: But we must also be conscious and aware of economies of scale, and shifting the burden of energy usage from one central server to N clients is ultimately not a good answer for NET energy consumption.

Layer 3: But for some constrained resources, that might be worthwhile, depending on the magnitude: The incremental cost of extra rendering on the client is a rounding error. But on a solar-powered low-energy server, it MIGHT be meaningful, and be the difference between something working and not.

This is a lens we must apply to everything:

* Logging
* Battery technology
* Buying locally vs economies of scale
* International shipping
* Container ships
* etc.
Not sure why you think clang having multiple not-identical executables is relevant to Backblaze having multiple identical executables.

I don't think that's the case at all. Most commercial software comes with a 'use at your own risk' license, or if you're really lucky, will cap liability at the amount you paid.
> Funny

Can you extrapolate on what you mean by this?
"Rotating" meaning sighted at an angle so you can use Doppler shifts of familiar spectra to figure out the tangential velocity of parts of the galaxy. In this case they used what they called "gas", meaning I suppose interstellar plasma, as the reference for the Doppler-shifted waves. They could check emission lines from the plasma, or reflections off it, or gaps in transmitted light representing absorption of that light by the plasma.
I think this case might be slightly different than the standard lockup issues. For example this quote:

> BuzzFeed sent an e-mail to former employees reiterating the need to print and sign the e-mail in order to make the stock conversion. “For context, only yesterday did we learn that holders of Class B shares would have to take additional steps to convert their shares to Class A,” it read.

I’ve never heard a company say they were ignorant of how their share lockup would work.

Anyway, this should be a lesson to everyone: don’t expect your company to tell you how to cash out after an IPO. You need to get your own advisers to analyze the legal and tax situation.
I was traveling in Rishikesh and there was an enormous pilgrimage for people to visit a temple dedicated to Shiva.
I learned of a number of fascinating traditions from the pilgrims.

One was to fill a water bottle with "Ganga Water" to splash onto some hanging fabric at the entrance of the temple.

On the 14km hike up the mountain to the temple I was invited to a chillum circle. As we sat around smoking and talking I saw one of the other people reach down and take a drink from the water bottles so many people had hanging from their belts.

I asked, "Is that... your Ganga water?"

They responded, "Yes! Would you like some?"

I said, "Thank you, but my body is unfamiliar with drinking Ganga Water. I think it will make me sick."

They replied, "Maybe you are already sick if you are unable to drink Ganga Water."
I wonder the carbon footprint difference for connecting this server to the power grid vs using battery and solar.
dYdX is a layer-2 zk-rollup-based exchange that is definitely not decentralized in the sense that e.g. Uniswap is on layer-1. It still, however, inherits the security guarantees of L1 despite not being directly intractable with from L1.
Visual Studio has bits and pieces written in pretty much all UI frameworks that Microsoft ever had - at some point there were even HTAs there, not sure if that's still the case. Some bits get rewritten, like the main window chrome / menus / toolbars (all WPF now). Some do not. That said, as I recall, the property editor that you get when editing WPF controls and forms is itself WPF these days.

But anyway, my point is that it was hardly "abandoned at birth", given that WPF was originally released with .NET 3.0 in 2006, while the first version of VS to get WPF UI was VS 2010 - and more was rewritten since then. Even if no new VS components are ever going to be written in it, maintaining the existing ones makes it necessary to maintain WPF to some bare minimum standard.

(The same goes for WinForms and other UI stacks that VS still uses in places.)
Now do the reverse develop something in Chrome or Firefox and expect it to work flawlessly in Safari. It most likely won't.

It's totally possible and many unpopular open source projects out there do just that.
You’re talking about the original link from esahubble? It doesn’t mention that at all. That’s why I went digging.
How old are you?

$10 says every passing year will make you less happy with renting.
In a true collapse I’d imagine almost every aspect of life is worse than the year before which sounds measurable and detectable.

But maybe a point of no return would be harder to detect. Like health is improving but resources are dropping to unrecoverable levels.
> You see, a box (the rectangular space taken up by an element) has several measurements: its own width and height, then surrounding whitespace called padding, then an optional border, then a margin separating it from neighboring boxes. CSS specifies that these properties are all additive.

I never understood why CSS picked the obviously wrong way to define the box model. Who in their right mind would ever think that "width" would refer to the inner width of a box? I'm glad they finally added box-model: border-box, but the fact that there needed to be a switch at all is ridiculous.
Crypto is not scarce,

I find myself extremely bothered by the artifacts from temporal super resolution. It's not blurry like temporal anti aliasing was but instead it's like anything fast moving has a detailed shimmer around it. I felt similar problems when DLSS was cranked way up in demos (and based on the blockiness of the unfiltered portion of the demo this is pretty decently cranked up as well). Some of the particle lighting effects aren't handled too well by it and end up look like streaking pixels.

Overall very good graphical quality demo, would love to see this on a maxed out PC without so much scaling/a higher framerate though.
My two children smelled very different as babies. They both had smells, yes. They both smelled good. But entirely different smells. So I'm not sure there's a "baby smell", per se, so much as babies are prone to emitting smells. And because we're protective and they're cute we likely interpret those smells as pleasant.

(Damn, now I want to have more babies, but we're almost 10 years past that possibility. And still nowhere close to grandkid babies.)
you beat me to it!
> If the tech gets past the uncanny valley then you'll never know. This is basically true by definition.

What are you offering here that I can't get from other, free alternatives?
Nobody knows. Galaxies like that were not supposed to be possible.
I'm 45, I've been renting for 25 years. I love the flexibility. I've never been forced to move by a landlord, though I admit it could happen, but I'd be fine to move. I've moved voluntarily about 15 times in those last 25 years.
Morality aside the uneaten dead birds never go to waste. If a raccoon, opossum, coyote or bird doesn't eat the carcass something else will and it all goes back into the mix. The only way it becomes an actual loss is when a human interferes by putting it in a plastic bag or throwing it out in the trash and dooming it to decompose in a landfill.
> A new study could change that. Researchers have identified an odorless compound emitted by people—and in particular babies—called hexadecanal, or HEX, that appears to foster aggressive behavior in women and blunt it in men.

The occurrence of pheromones in the animal kingdom, but so far scant evidence in humans, is a puzzle:

Maybe there really are no human pheromones. Or maybe they're just really hard to study because studying human behavior is so hard in general.
It's in a postscript attached to a sentenced about how giving away software is what helps him sleep at night. I'm not sure how you can reach any other logical conclusion without throwing out data from the article in favor of completely off-topic items.
Exactly. I don't expect to be able to follow an NPC and see a life-like routine, just something convincing enough.
Slightly related anecdote: one of my kids was born with a full head of hair. The hair was the softest thing I've ever interacted with in my entire life. We also have black cat with silky fur that usually feels soft. When the baby came home, the cat's fur might as well have been sandpaper. It took weeks for us to feel the cat's fur as his normal self.

The thing here is that babies have this ethereal and indescribable effect on the people around them which postmodernist science is now trying understand.
Will people die during the ramp up of FSD? Yes, absolutely. But if this is the only question you’re asking, you’re missing the point.

The other question you need to ask is how many lives will be saved once we have FSD?

That number will easily be 10,000 lives per year. That dwarfs the number that will die due to FSD by orders of magnitude.

It is imperative that we figure out FSD as quickly as possible, that means doing real world beta tests using a large fleet, just as Tesla is doing. There will undoubtedly be lives lost in this process, just as there are innocent lives lost in a huge amount of Endeavors we are
Undertaking in other areas.

And as far as pedestrians being forced to put their lives in the hands of these beta testers, are the same pedestrians not already putting their lives in the hands of drunk drivers, and drivers who aren’t paying attention while using their phones?
Video game development. The pay used to be worse but it has actually been getting somewhat better lately.
It's currently a standard Geth node due to storage limitations (a 1 TB disk for both Geth and Lighthouse). I'll bump the storage up next year to 2 TB (or more), so I can run an erigon archive node and thus won't need to prune geth regularly either.

Nice! Are the early msdos versions basically the same?

Added: the comments in those files are better than nothing but they don't really say what the program is doing the way the original source code hopefully would. The labels are still the ones generated by the disassembler, so not very informative. Still, it's nice that someone did this and it's a good starting point for further study by anyone sufficiently motivated.

If of any interest, the source code to the BDS C compiler of the same era was released here: https://www.bdsoft.com/resources/bdsc.html
It's something the average person doesn't need to think about, until some tragedy grabs people's attention. Then hopefully it will be fixed and become a problem of the past, once again something we don't need to think about.

Seems to me the real issue here is only 6% of the money pledged to the SPAC stuck around. Presumably the market wasn’t keen on the listing or the valuation.

Or am I misunderstanding how SPAC’s work? My understanding is people commit hoping the deal turns out good and can walk if they don’t like the deal. Presumably they don’t like the deal.
