Yes,

> 1 for any prime; everything else calculated via the product rule

does indeed have a surprising amount to do with differentiation!

If you take the usual polynomial functions in one variable (lets say x is the variable and all our things are complex numbers) then these can be factored: e.g. x^2 + 3x + 2 = (x+1)(x+2). They form a (so called) unique factorization domain, which essentially means that factorization into "primes" works exactly the same as it does for integers. In the example above (x+1) and (x+2) are examples of prime factors which can't be factored any further.

If you take the definition "1 for any prime; everything else calculated via the product rule" and apply it to this system where our "numbers" are polynomials and our "primes" are the polynomials we can't factor any further you get a definition of an "arithmetic derivative" for polynomials.

The fun fact then is that this arithmetic derivative we just defined is exactly the same as the usual definition of the derivative from calculus:

D[(x+1)(x+2)] = (x+1)D[(x+2)] + (x+2)D[(x+1)] = (x+1) + (x+2) = 2x+3

whereas

d/dx (x^2 + 3x + 2) = 2x + 3
Same! I think it was back in 1997 in college, and my dorm mate only had 4 floppies sitting around, and Slackware was around 50, so I kicked off the installation with the first couple of disks, and when I'd finish up with one I'd toss it across the hall to him, and he'd reimage it with the next in the sequence and toss it back. Pretty tedious, but it got the job done.

I'll never forget how foreign Slackware felt after having grown up on DOS. It wasn't long before I got used to it, though, and I never did go back. Great memories.

By far, the worst memory leak I’ve ever had to debug involved a cycle like you are describing, but it was in a Java program (swing encourages/encouraged such leaks, and “memory leaks in java are impossible”, so there weren’t decent heap profilers at the time).

For the last few decades, I’ve been writing c/c++/rust code, and the tooling there makes it trivial to find such things.

One good approach is to use a C++ custom allocator (that wraps a standard allocator) that gets a reference to a call site specific counter (or type specific counter) at compile time. When an object is allocated it increments the counter. When deleted, it decrements.

Every few minutes, it logs the top 100 allocation sites, sorted by object count or memory usage. At process exit, return an error code if any counters are non-zero.

With that, people can’t check in memory leaks that are encountered by tests.

In practice, the overhead of such a thing is too low to be measured, so it can be on all the time. That lets it find leaks that only occur in customer environments.

Unfortunately, NIMBYism is popular in both parties on the local level. But note that California Democrats did take action to force permitting of more dense housing on the state level.

Also, on the state level, Democrat led states have higher minimum wages, stronger labor protections, parental leave and paid leave in general, expanded Medicaid, and other policies that raise the floor in general.

Kids love a projector that responds to their movements. So a movie of fish swimming that respond as the kids run around in the water.

I saw a cool one that had a water fall on a wall that became a river on a floor and the kids could take cushions and divert the river by blocking its flow. The 7 year olds would like that.

4 year olds like physical challenges. So you could use the projector to do a dynamic hop scotch or jumping game with Lilly pads.

I am actually not a big fan of getting kids involved with devices though. I think they need to learn to play in groups, spend time outside, and learn to be as physically capable as possible.

I think if you use tech it would ideally be to teach them a rule based team game where they have to work together, user their imagination and solve a problem.

KeePassXC has no sync implementation.

The functions related to Internet are:

- checking entries against HIBP (needs to be done manually in a submenu with a giant notice)

Also this is about KeePassXC not KeePass which is a completely different project.
There is also KeePassX, KeePassDX, KeeWeb, KeePass-electron and so on and so forth.

Many engines, especially early on, can accept any external heat source as power. The most currently popular version of this is a Stirling engine, where you can find many toy engines of this type, like the wide bodies ones you can put on top of a hot drink.

Internal combustion was not actually popular for quite some time in early engines, I assume because it has more advanced requirements for fuel and ignition control, so if solar were a convenient enough power source it would have been used.
You made me chuckle. Mission accomplished.
I've sworn by 7zip since forever and I still use it primarily, but I'd recommend peazip to anybody who wants 7zip but with a better, more convenient GUI (and workflow/behavior). I still think about switching back to peazip (only used it for a few months), but old habits die hard.

Have them try to ID common yard broadleaf “weeds”, which imo have rather nice (if small and hard to notice) flowers. Learning things like:

1. What conditions they like

2. How they behave over time

3. What insects are attracted to them or eats them

…puts them in touch with the world.

IDing grasses is much harder, even for me unless it has a seedhead out or you have a microscope and know how to use a species identification key, so I wouldn’t bother with those.

PlantNet.org has a pretty nice app to assist ID with photo, but you can’t take the first result at face value.
More the first than the second.

There are things other than the integers for which it makes sense to talk about "the primes". One example is: polynomials (with coefficients in, let's say, the complex numbers). In this case it turns out that the "primes" are exactly the linear polynomials (ax+b) where a is nonzero.

There's a bit of ambiguity there, just as there is in the integers; 7 and -7 are "the same prime number", and x+3 and 5x+15 are "the same prime polynomial"; if we're going to say D(p)=1 then we need to pick which "version" of p has this property, and the obvious choice is the one of the form (x+a).

So, now, if we apply the same definition as for integers to polynomials with these conventions, it says: (1) D(x+a) = 1 and (2) D(fg) = fD(g) + D(f)g when f,g are polynomials. And that turns out to give the exact same result as the "ordinary" derivative for polynomials.

Whether "exactly identical to" implies "a surprising amount to do with" depends on how easily surprised you are, I guess.

... I glossed over the sense in which the "primes" are precisely the linear polynomials, so here are a few words about that for anyone who's curious.

If we look at polynomials with complex-number coefficients, a beautiful theorem says that they can all be written as A (x-r1) (x-r2) ... (x-rk), and then one polynomial divides another if and only if its set of rj is a subset of the other's (handling repeated roots in the "obvious" way). It's pretty easy to get from this that the linear polynomials are (1) the irreducible ones, i.e., the ones that can't be factored into lower-degree polynomials, and (2) the prime ones, i.e., the ones with the property that if p divides ab then p divides either a or b. (These properties are equivalent for the integers, as well as for polynomials with complex coefficients, but there are other settings in which they come out different, and both of them are useful, so they have different names.)

(What happens if we use real rather than complex coefficients? The Wikipedia "Arithmetic derivative" page claims that we still get the usual derivative, but that looks wrong to me, because if we work over the real numbers then x^2+1 is both prime and irreducible, but its derivative isn't 1. Maybe I'm missing something.)
No. A DO only exists in a single edge location. That's the entire point of Durable Objects.

D1 will replicate soon, but doesn't do so yet. My understanding is that it will replicate to ~5 locations and keep these locations fresh.
I dont get why people elsewhere on this thread are so up in arms about it - it seems like a perfectly reasonable interpretation of federal law, consistent with other kinds of civil claims.

Tying the ability to recover damages not to the date of the action that caused the loss, but rather to when you discovered the loss seems more reasonable.
The thing is, adding an inline fuse doesn't guarantee that the host would be safe: if the fuse doesn't blow quick enough and lets enough current through, that's bad (plus, you'd have to add a fuse to P-, D+, D- and P+ just to be sure, not to mention USB3). The best option would probably be a complete isolation of the USB device from the host, with a hub that then transfers D- and D+ to the host without a direct electrical connection (while providing its own P- and P+). Think TOSlink, but for USB.

Programs like 7-zip and PeaZip both have an unusual feature: Ability to explore NT paths that Windows Explorer will refuse to load.

You can go to a path like "\\?\Harddisk0Partition2\" in 7-zip file manager or PeaZip. On my PC, that happens to be the EFI partition. (Need to run as Admin before it lets you access the EFI partition)

Sysinternals WinObj will let you see all the paths in the NT Object Namespace. To convert an NT Object Namespace path into a standard Windows path, put "\\?\GLOBALROOT\" at the beginning of the path. Windows Explorer and the File Dialogs will refuse to open such paths, but many Win32 applications will accept those paths as command line arguments.

I’d be curious to know your recipes/plans - I can never seem to get something that’s healthy, cost conscious, and stable for 2 weeks in a prep plan.

For myself, I eat a lot of the local grocery store’s (HEB which I like a lot) prepared salads and sandwiches. They also sell a lot of pre-seasoned meat for grilling that I rather enjoy. Also we have a ton of Texmex restaurants here which are fairly unhealthy, but you can do pretty good if you divide one of their meals in half and get two servings, and the price for that is usually around the cost of a single fast-food meal. I also have the privilege of sharing a lot of meals with my parents and aunt/uncle as we are all locals.

Regardless, the point remains. Peanut butter is never fresh if it's in a grocery store. If you want fresh peanut butter, you'll need to find a way to buy it unsealed within the day made from the manufacturer or make it yourself.

Really, fresh peanut butter would really just be blended fresh peanuts until it reaches the consistency you want. That's a lot easier to do than making your own salad dressing.

> I find that comparing an autocratic government to others that at least have some semblance of democracy is pointless. It's a certainty that in an autocracy companies and individuals have much less control over property, including their highly valuable digital data.

I think my characterization is less misleading than yours. This isnt the application of existing discounts to an industry initiated desire for a fixed fee. The income based fixed charges to come into compliance with new state law AB-205 [1]

Here is a summary from the AB-205 itself: "The bill would eliminate the cap on the amount of the fixed charge that the PUC may authorize. The bill would require the fixed charge to be established on an income-graduated basis, as provided, with no fewer than 3 income thresholds so that low-income ratepayers in each baseline territory would realize a lower average monthly bill without making any changes in usage."

Either way, the law and it's predecessor require income discrimination by private companies, opposed to subsidizing low incomes from the general fund. It is absolutely a income redistribution transfer payment that doesnt go through the state taxes or the state budget. Ironically, this bill was passed as a trailer to the state budget [2].

It only really impacts people that don't own a vehicle, something like 10% of households. In urban areas, most housing is within a couple of miles of a real grocery store (so access with a vehicle is not an issue).

In my relatively rural county, the food deserts are mostly outside of the towns, where people, for the most part anyway, are living there by choice (they want the outdoor space/distance from neighbors).

The problem I can see is the extension of the period of damages. There is an argument to be made that there should probably be a statutory cap on years for damages accrual rather than just 'as long as you infringed,' but that's for the legislature to do.
The label can also be wrong. Just because someone stamped a product with something doesn't make it a fact. It's just the manufacturer's opinion on the matter, and their opinion may be or may not be credible like every other source of information.

Just because they appear authority-like does not make their opinion more valid.
I have no horse in this race, or at least I have no more horses that anyone else, but I can honestly say, no hyperbole, no panic-button... 20 years ago, winters used to be winters, temperature used to be low for months, snow would accumulate and every day would be a chore to clear out at least 40 to 50 cm of snow, just to get to the street. Last winter, it snowed twice, only a few hours each day, and this has been the case for years and years now... something has definitely changed, in fact, something feels broken... I live about 2 hours from Antarctica, so think about it.

Incentive for a demo isn’t new. It might increase your demo rate but might also introduce some leads to the funnel that want the incentive more than they want to learn about your product. So my recommendation to you would be to share the incentive with qualified demos, a questionare is nice, but a qualified demo is pipeline.

The United States federal government is bought and paid for. This withering of Constitutional rights basically started with Wickard v Filburn.

At this point, I do not recognize the legitimacy of the US government. They enjoy a monopoly on violence, yet they disrespect the bounds placed upon them and find wiggle room to shake them completely off.

Some might say this is cold, but I kind of wish COVID had taken out a lot of the people actually responsible for the current state of this mess. The only way to fix things at this point would be to tear it all down and start from scratch, and the only way to do that is to find a way to remove all of the people from power who enable it and who further erode the rights of individuals. COVID taking them all out would have been a very convenient way for that to happen without someone being branded a terrorist.

There are many first computers, depending on what adjectives you apply. The "official" claim is that ENIAC is the "first electronic, general purpose, large scale, digital computer". For an interesting exploration of what computer is first under what definition, see the interactive website https://www.gleech.org/first-computers

I highly recommend the book "ENIAC in Action" for a thorough discussion of the computer.

Personally, I view ENIAC as the first influential computer, in the sense that it made multiple groups decide to build computers and thus started the computer revolution. If you went back in time and stopped ENIAC, it would have set back computing by years; the impact of earlier computers was small.
As far as your point in parentheses goes, I think wikipedia is either wrong or confusingly written (allowing complex factorisations of real polynomials makes what they're written consistent, but is a bit silly).

One can make nutritious under $4/meal on organic WholeFood prices when sticking to raw materials, i.e. not prepared foods. Those with access to a yard in the right climates can improve on that with some garden beds (herbs & leafy greens have a good return). So I think that really depends on what you're purchasing at the store.

Fast food chains have the benefit of scale but they still have margins to make. That food is rarely healthy so you're also increasing your long term healthcare costs by going that route.

I believe that a major issue here is that many of the younger people in the US haven't gained the skills to cook for themselves. With those skills comes efficiency and the ability to reduce waste. For those working low wage jobs (of which I was for about a decade), time spent on cooking has a higher value than say a knowledge worker who can pick up some contract work on upwork.

I feel we've grown far too used to cheap food in the US. Particularly meat which relies on consolidation into large operations that require antibiotic use, cheap labor in poor conditions, and questionable practices in processing and livestock welfare. So yeah, perhaps that happy meal should cost more?
