Bitten by queues in every team I was at AWS:

> As a rule of thumb, target utilization below 75%

This is one good reason to rely on serverless. Simply outsource the problem to a system that knows how to handle this better.

> Steer slower workloads to paths with lower utilization

This is fraught with all sorts of perils [0], so take caution going down this valid but tricky route.

> Limit variance as much as possible when utilization is high

This is key, and one of the most elegant solutions to this problem I know of comes from a Facebook talk on CoDel + Adaptive LIFO. [1]

> Implement backpressure in systems where it is not built-in

Making downstream dependencies behave is never an option. Selectively isolating noisy neighbours, if possible, from other well behaved clients, tends to work well for multi-tenant systems [2], in addition to monitoring long work (by dropping work that takes forever) [3], or better yet, doing constant amount of work [4] (aka eliminating modes) [5].

> Use throttling and load shedding to reduce pressure on downstream queues.

One way is to impl admission control (ala Token Bucket) to minimise the impact of thundering herds. Though, clients do not take kindly to being throttled. [6]

A great article; many have been written at this point. Very many still have been burned by queues. Though, in my experience, without an exception, some component somewhere was always building up that backlog! [7][8][9]

Pre-Product Funding
Is there anyone here who has raised funds for a pre-product? What was your impression of the situation? I'm stuck, but I'm not giving up (and I'm not going to) - I've been working on an idea (I'm a UX guy), and now I'm looking for investors who are interested in individuals like me. If any of you can offer any suggestions, I would be grateful. I'm seeking a technical co-founder as well.
Only 13 % of Chinese emissions are caused by production for other countries. That 13 % isn’t just the West but the whole world.

And putting solar on roofs tend to reduce cooling costs by a few percent for a building due to the shade.
> At some point - it's simple. Just pass on a carbon tax on any good, regardless of which country it is created on. Taxed in the country of destination.

I don't think it's so simple, actually. My experience is that when people declare big sweeping "simple" solutions to global problems, those solutions tend to backfire and make things worse.

Determining how much CO2 was emitted during the production of any particular good is quite difficult to do. Are you going to parachute some UN Carbon Inspection Team to investigate the BOM for every manufactured good and add up some carbon tally? How will they know whether some wire was made in a solar powered factory or a coal powered factory? And what about the inputs to those factories, etc? And why would China allow such inspectors?

You will not be able to get that type of per-item granularity.

But you can get general info about countries. OK, what do you do with the general info? Apply the same tax on all goods, or just invent some hypothetical carbon burden for each good produced in a given country? That's a great strategy for getting producers to reclassify goods -- e.g. from passenger cars to personal utility vehicles, or for diverting goods from one country to another.

Moreover here, you've switched from trying to use the market to incentivize behavior to collective punishment of producers, where producers who use green energy sources are also forced to pay the tax.

But then why would other producers change behavior? Moreover by adding these extra tariff costs, you are going to be driving producers to look for even cheaper inputs, and that means more fossil fuels.

Moreover, that's just going to result in counter-tariffs and punishment in the reverse direction.

So you will be punching China and getting an equal punch back at you, and none of that will do anything to reduce CO2. All it will accomplish is a lot of punching in all directions -- e.g this is a tantrum-based approach to CO2 policy.
Don’t canceled/rejected requests have infinite latency by definition?
That keeps being mentioned but there hasn't been been a solid example. And I think it'll be a while before the lower end TVs at Costco have that, especially with our cell costs in Canada.

At best it's an ongoing research project. It's wise to be skeptical of IBM statements/announcements/predictions given their track record over the last couple of decades.
> mental illness absolutely hinders one's mental capacity and works against it, rather than something that assists it.

This is too much of a generalization. I think that is mostly the case but there are obvious benefits to obsession and hypomania if that can be channeled, and sometimes it can.
Ah yes, "technobabble".

I'll go back to porting Linux to this thing then; clearly you're not interested in hearing about how these things are designed.

It doesn't take being a senior hardware engineer to be able to count bus width and calculate bandwidth, though, so I'm still curious how you want a laptop built with the 8 DIMM slots it'd take to match the memory bandwidth of the M1 Max. Remember, these things have high performance integrated GPUs, that perform at the same level as discrete ones. Ever wonder why discrete GPUs haven't had modular RAM for a couple decades now? Yeah. Bus width.

> high performing modular RAM architecture already exist

The M1 Max has a memory bandwidth of 409 GB/sec. A top spec EPYC server (Rome) chip has 410 GB/sec of memory bandwidth, with 8 channels populated with the fastest RAM they'll take.

Indeed, high performing modular RAM architectures do exist. In servers that eat huge amounts of power and require 8 DIMMs to go that fast. Good luck fitting that into a laptop.

But I guess this is all still just technobabble to you :-)
We could have a dual/varied interest rate policy where different rates are set for different policy ”targets”. Tltros - targeted long-term refinancing is one example in Europe. Banks receive extra yields on government debt for lending that money in specified ways.
Yes, pass a tax. Not just on goods but also services: Flights, heating, taxi rides, bus tickets, food delivery etc.

This doesn't really work. Nimby is "I want this, but not near me" but the examples you gave are "I want this but no one is selling this to me." The difference is that in the first scenario someone is presenting a solution and people are saying "no, not like that" and in the second scenario there's no solution presented and people would probably buy them if they existed (or were just as convenient).

Potentially, but that's not what killed Xerox (who had a decade head start on Microsoft and Apple and had full visibility on what they were doing in the marketplace for another decade before GUIs became commonplace).

They fell victim to the Innovator's Dilemma: when a new technology comes out that fundamentally rewrites the rules about who your customers are and how markets should be organized, existing market leaders cannot maintain their lead. That's because their market itself gets restructured - where previously one market with a dominant firm and set of existing customers used to exist, now oftentimes new markets with new dominant firms and a new set of customers exist. Basically it rewrites all the assumptions that the business is structured around.
In the military context, violence is an option. Powerful radio transmitters are vulnerable to anti-radiation missiles: https://en.wikipedia.org/wiki/Anti-radiation_missile In a free fire zone a GPS jammer would have a lifespan measured in minutes. A hypothetical conflict with a near-peer would involve a lot of jam and counter-jam drones destroying each other, until both sides run out of equipment.

A more interesting attack would be jamming the M code and then spoofing the data on the civilian band, which is one hypothesis for what happened to the RQ-170 that Iran soft-ish landed: https://en.wikipedia.org/wiki/Iran%E2%80%93U.S._RQ-170_incid...
My understanding of the argument is that institutional racism means all the white people simply didn’t think about photographing dark people. Not so much “omg evil they purposely excluded blacks!!” and more “wow it didn’t even cross their minds as important, if there were more black people in those positions they’d probably think of that”

ie. it’s about using more inclusive test cases and acceptance criteria for engineering projects

Edit: then again they could still decide to make the tradeoff to “ignore” 13% of the population in their products if the extra engineering required increased costs/time by enough
The OP's #2 is actually an exponential growth in money printing.

If the growth stops being exponential, it moves away from the target in an exponential way. If the growth just becomes an exponential with a smaller exponent, it moves away from the target in an exponential way.

In theory you could have an exponential that grows in a very slow, controlled way. On practice, it will get out of control, because nobody has any idea what the target actually is, so you either always correct towards it, or deviate.
everybody is learning regex, it's part of any standard curriculum, it's in everyday use on unix platforms, rigid implementation without variables or recursion is a regular automaton has a firm place in the computational hierarchy and the benefit of predictable runtime, the markup is just syntactic sugar, and you can of course embed regex in any more powerful programming language that allows variables, like awk, perl, etc. Perl, hardly anyone wants to learn anymore, if that's what you mean.
A major modern greenhouse operation I saw recently dealt with this by spraying the exterior with some sort of chalk solution (I think). Just made the glass panels look slightly opaque. Then they'd wash it off when they needed more light through. In this case, there was generally less rain when they wanted the solar protection, so they didn't have to worry about it washing off out of schedule too often.
> As such, couldn't Apple just treat .app bundles (and a few other bundle types, e.g. .framework, .kext, .plugin, etc.) specially for purposes of iCloud backup, by e.g. content-hashing all the files in each bundle, shoving those files into an object store keyed by content hash (i.e. a Content-Addressable Store), CDN-mirroring that CAS, and then saving the .app bundle in your backup as a BOM for reconstructing the bundle from the CAS CDN?

Many macOS apps are not sandboxed. Even apps which have native iOS ports litter crap all over the macOS filesystem. Of course, the primary offender is apps which have their own always-running autoupdater services.

My money Apple will eventually do a devteam-bound overlay filesystem for apps which have not adopted sandboxing.

> Keep in mind, Apple have never promised E2E encryption for iCloud backups, only "encryption in flight" and "encryption at rest." (See https://support.apple.com/en-ca/HT202303). And even then, that's never included an implied encryption of your applications, only of "your data" (since, as you say, the apps are being turned into symbolic references to ITMS CDN objects.)

I don't know if Apple wants to have more caveats to their privacy story at this point.

I suspect the best system would be the hash-encrypt-hash of Freenet, at which point the privacy leak would be in the downloading/leasing of blocks of identified material - e.g. if someone was upset about a particular app being pirated they could still court-order ask apple for information on which devices were backing that object up.
I hope to get an electric car soon, and it would be great to be able to charge at work - even if I had a home battery. And I'm sure there will be programs to encourage businesses to get chargers into car parks around here in the next few years - and since cars are parked for a fair while, it can just be slow charging like 7 kW single phase (I guess it would make sense to also have two or so fast charging spaces for when people need it)

Charging at work would be ideal - it would all basically happen 100% in solar hours. My work has solar on its roof itself, I'm sure more and more places will, so it all really makes sense. And that way I could basically run my house 100% off a battery, whereas charging an electric car from a home battery would probably mean I'd still have to buy a fair bit of power from the grid.

But yeah, the story basically is that it's all possible and not that hard.

> > land, trees, and nice quality living.

I have the feeling they're talking about land in their area that they don't own, that for whatever reason is prevented from being used for new homes, and their worry is that zoning changes allowing it would ruin the quality of life there by removing the greenery and open spaces.
> azure:

> sky-blue color; pigment or paint made of powdered lapis lazuli," early 14c., from Old French azur, asur, a color name (12c.), from a false separation of Medieval Latin lazur, lazuri (as though the -l- were the French article l'), which comes from Greek lazour, from Persian lajward, from Lajward, a place in Turkestan mentioned by Marco Polo, where the stone was collected.

So there you go. Azure because of where Marco Polo happened to get a blue rock.
Instead of artificially limiting demand I think it'd be better to stop artificially limiting supply (zoning). If there was enough housing to meet demand, then it would naturally be a poorer investment, and so rich assholes would stop buying so much of it.
IMO using code that generates (possibly binary/opaque) config data is the sweet spot. It's one more layer of indirection, but it means you're language-agnostic, you have a "safe" interface, and your "config-generating" process can be as expressive as you like -- comments, loops, whatever.

The underlying conundrum is:

- systems need to be configured,

- human-readability is obviously necessary at some level,

- configuration is often very "compressible" (needs loops, needs variables to be maintainable), but

- system-writers don't know the structure of your data, the axes on which you'd want to compress things, the best abstractions for you.

Templating languages are an obvious direction, but they're uniformly bad. If they have limited expressiveness you'll run into the limits. Maybe there are templating languages with good unit testing frameworks, but I haven't seen them. "Look at the expanded diff" doesn't scale. And generating gobs of human-readable "data" (in a format that supports comments!) is very wasteful.
That’s not an unreasonable opinion, but to answer your question “why”, the answer is because a democratically elected state legislature has decided it’s in the best interest of their constituents to make it this way. And state power supersedes municipal power.

Nobody’s upzoned a state over one nice expensive neighborhood but when the crisis starts harming the state economy, then the state legislature obviously cares.

A Pi-Hole can also break your TV interface, like it does with Samsung TVs after the recent updates they expect the ads to load when they don’t things get messy.

I think out of the major brands only Sony hasn’t been pushing ads so far at least as far as their premium models go.
SF water is piped in because their groundwater is depleted and they are using other areas water. This led to the shutter of several cities at the time (1900s ish).

While farms do use significantly more water, they also are not in the city and they produce food. Farmers generally feel they should be able to use their water instead of the city leeching it.

50% of the developable land in Seattle is designated for single-family homes, and not one single inhabitable SFH in Seattle city limits is what anyone would call "affordable". The fact that it's illegal to replace those SFHs with duplexes, quadplexes, or midrises is a primary driver of housing unaffordability.

Seattle's population growth has outpaced its housing growth for multiple decades. There's a huge amount of "catching up" to do, and SFH zoning is blocking that from happening.

Once enough there's enough housing to hold all the rich people that want to live here, of which there are many, you will see some downmarket construction happening. But we're a long way away from that.
Is there even the workers needed to build all these houses we need? We have in my city a plan for a >4000 houses to be built. I asked my brother who is a carpenter how could they do that. He said either a lot of workers and some time or fewer workers and a lot of time. The company he works for already struggles to find skilled workers to build houses so makes me wonder how can we build all these places when it seems the crews are already currently too busy.

> The shift over years has been that the second strategy produces more crops with lower expenses than the first, and is taking over to the extent it is almost impossible to run a small farm without going bankrupt.

While true, you can lease the land making a decent income without effort. Which is the best case scenario as many older farmers retire and leave the land to family.

On the other hand, if people still are looking to make a living, it's more focused on livestock such as cattle, chickens, pigs, etc often niche animals.

My problem is I lose them. I bought the Bose QuietComforts earlier this year and have lost one or the other a couple of times already. Right now one is sitting in the console of my truck and i can’t find the other one. No clue where it could be and of course the batteries are dead.

It would be nice if they all had Tile or similar tech, but if their batteries go dead just sitting there (super annoying thing about the bose) then it’s useless too.

Not sure what you think "my side" is, but I appreciate the response. I know you have better things to do. Sorry for the meta-discussion.
Because of NIMBY. Basically the rich people at the city's center won't let regulations pass that would increase density and therefore more poor people living around them. They like the current status quo because "they got theirs". They limit what kind of housing can be built, how tall it can be, etc and price out all but the richest land developers who in turn charge ultra high rent for the limited housing. I don't even think they necessarily need to build "poor" housing as much as loosening regulations and allow other than historic buildings to exist.
