Congrats on the launch!

Combining policy with Zanzibar is super cool and it's great to see the folks in the OPA ecosystem moving in this direction. Most of the novelty of the Zanzibar paper is about scaling ReBAC systems that might not be applicable in a system that starts with policy. Unfortunately, I found the website a little vague on technical details and had some questions:

- I'm curious how this is different from using an API client in rego, which other projects like OpenFGA and SpiceDB support.

- It seems like for the variety of projects in this space "Zanzibar" is used to mean many different things mentioned in the paper. Can you clarify which properties Topaz is inspired by? From the documentation, I can only find references to tuples and union rewrites[0].

Disclosure: I work on SpiceDB, an established open source project also "inspired by Zanzibar" that also has policy integrations with OPA and Google's CEL.

Yes, because you would still have to know a valid hostname to actually get anywhere. This of course assumes no bugs/vulnerabilities in the web server.
If you’re only getting 500qps out of Netty something is deeply wrong with your set up. I’ve written multiple HTTP & socket servers based on Netty (albeit 6+ years ago) and they all could handle 20kqps+.
Resident Evil Village is launching on Mac with Apple Silicon support

Often, utilities and laws make it irrationally difficult to use solar and grid at the same time. You'd need a grid tie system (if permitted), or loads that you can run off solar alone (not connected to your home wiring).

I can totally see the rationale for buying panels, and an inverter, such that I could feed into my home if the power went out - but not going through the mess of permitting, just planning to hook it up if the apocalypse does occur.

I don’t think anyone means to put ALL calculations through a reduced representation. That’s a terrible idea. But if you are discounting cash flows or something, it won’t make that much of a difference if you leave the discounted version in full float / double representation and then add them or reduce them to 2 decimals before adding*

High finance uses float / double in general and doesn’t bother with the nuances of decimal representation or IEEE 754 unless they’re working too close to the silicon rather than doing model work in higher abstractions.

* software that allows only 2 decimal representation must account for these discrepancies by default even if it’s only off by a few cents

> In 2017 Portland ranked third. Now it has dropped to 66th out of 80. Polling in May for the Oregonian newspaper found that 53% of residents in the metro area felt safe downtown during the day; only 20% felt safe there at night.

Portland and Seattle are becoming filthy and trying to destroy themselves. I'd rather not have the same policies empowering the next age of innovation in USA. There are much better places, and much better cities than what's happening in west coast.

The nice thing is that nature will find its way, there is no skirting around the truth of what's happening.
> so why aren't most people focused on learning + putting into practice, the techniques of a few very popular courses?

Because that entails hard work.
If we all agree that free speech is a vital aspect of a healthy civilization 'in real life' or 'offline' and that humanity is exponentially moving towards 'digital lives' – It would seem that it is probably very important for free speech to make the digital leap. It seems very bad to allow private corporations to be the arbiters.

One interesting solution I'm aware of is to utilize blockchain technology for the base social layer (L1). All communications or 'posts' can be minted onto a blockchain. Once minted, they could not be (easily) censored. The token provides proof for who shared the communication (important defense against fakes) and could provide fascinating provenance for the origin of specific ideas.

The token feed would display chronologically and include 100% of minted tokens. At a certain scale this feed would become dizzying and essentially useless. This is where the next layer comes in (L2). Call it the curation layer. This is essentially what twitter, facebook, instagram, tiktok, etc are today. The difference is that they are not pulling in their content from a base layer, rather the content needs to be created individually on each of their platforms. On the social blockchain anyone and everyone would be allowed to create a curation platform at L2. These curation hubs could choose to show or not show whatever they want. Some very popular platforms would surely gain favor, but some people may decide to handle curation on their own. Curation on L2 would allow very healthy competition and significantly reduce switching costs. This is because we'd be able to switch curation platforms without having to disturb the network effects as they'll be preserved by L1. It's very hard (though not impossible) to switch from platforms like twitter, facebook, instagram, etc due to the network effects they've built up.

This solution also provides an interesting opportunity for individuals to own their own content online and control aspects of their privacy. As the owner of all social tokens that I mint, I could have the ability to deleted content at L1 and have it disappear across all instances at L2. (though there def still needs to be a lot figured out there).
Happens to DJs too.
An always-on camera would be my favorite cyborg eye use case.

Imagine being able to go back and relive memories from your perspective. ML could be used to automatically caption and bookmark significant events for searchability.
> Plastic pollution is caused by bad management of it (and accidental loss) that spreads it into nature.

The idea that nature is over there, not here and that the landfill site is somehow ok to ruin has strong vibes of the (fantastic) comedy segment where the oil spill happens outside the environment.

no, being on a board is a pretty normal thing, and it is common for people to sit on them in addition to their job. The board of directors for my preschool was composed of garbage men, teachers, farmers, and parents.

Obviously some boards are different than others and expect different skills and connections.
I am a body purist, but I understand why people are curious about these things. More functional than navel piercings, at least.
First thing I looked for is how long does it takes to delete a document from the index.

Looks like it rebuilds the whole index periodically and that's very processor intensive. The delete will be reflected after a rebuild.

I'm becoming more and more convinced we need to multiply anything that is not strictly a probability (CIs, ML model scores, p-values) by 100.

"I have a confidence of 95" has very different ring to it than "I am 95% confident."

It would also prevent people from doing stupid things like using these values to compute expectations.
In capitalism, growth is the only meaningful metric. Housing has now been commercialized, too, after all.
The issue is the aggregation of such a volatile concept such that entire markets can be based on such pricing model.

That way lies the enablement of massive fraud.
Condescending much?

> Web3 is often more interested in moving money around (e.g. "Ponzi Schemes") than really creating anything.

And "Web 2.0" was more interested in taking some Unix utility and turning them into a web service that could be walled off and monetized. There hardly was any ~real innovation~.

See how ridiculous it sounds?
Whatever we call technology is as natural a process as everything else systems in our Universe cobble together. I see no difference between termite mounds and the Internet. All is bound by the laws of physics. The same processes created complex monkey brains create datacenters. Physics is very clear: only things that are thermodinamically downhill can happen. Human civilization is just a natural, 4D phenomenon we get to see unfold. All in all it won't amount to more then any passing geological pattern on any planet before or since.

My opinion is: make it correct unless it distracts from the story/gameplay. Most people won't notice but those who do will be happy. On a AAA game, you can afford to hire a couple of medievalists and get these details correct.

Sometimes, factual errors are actually deliberate in order to improve gameplay. For example, accurate architecture may take a back seat to level design. Weapons may react in completely unrealistic ways, but it is understandable because in real life, people didn't fight with controllers. People go much faster than they should, distances are shortened, there is either too much or too little variety because having too much of the same thing is boring and having variation is every small detail is too expensive. All that is not just excusable, it is actually good design, it is a game, not a history lesson. Sometimes, though it is more relevant in movies, there is a deliberate inaccuracy just because that's what people expect and doing it differently would make the audience focus on an unimportant detail or mess with the pacing. And sometimes, it is just to save money that is better spend elsewhere.

I don't think having period accurate pigs is any of these, so for me, it is a mistake, no more, no less. Not the worst, but it deserves a "bug report".
Yes, and we only need to look at the banking and investment sector to see how well this sort of thing actually works. These are all employment bills, written by the consulting companies who are going to be the ones to take the call from the Fortune 1000 companies that have to implement the regulations, and precious little of what happens in all of this activity actually accomplishes the stated reasons for the law.
AKA the Chinese/PRC model, you need a shit load of actual mk1 eyeballs to filter internet into hugbox for political/domestic serenity. Why western platforms had to pull out of PRC (again, not banned) after minority riots, because they couldn't stomach the onerous moderation costs required to operate in PRC that other PRC platforms had to endure. A few years later, radicalization on western platforms compelled the same measures - CCP has consistenly been prescient in domains of mass communication. Fringe voices are loudest in an unrestricted enviroment, it takes a lot of resources to put up walls and prune weeds for popular yet harmless mainstream stuff to stand a chance.
Buying a home during covid was a sound financial decision. Interest rates for a new home were ~2% which are INSANELY good and well below inflation.

Radiation is easy:

There is ionizing radiation (that affects matters as it travels through it) and non-ionizing radiation (that doesn’t affect matters as it travels through it).

X-ray is of the first kind. Decay radiation is of the first kind.

Wireless communications radio is of the second kind.

You should really focus on pollution and not on non-issues. Btw: air pollution killed more people over the same period than did Covid.
Great advice but for many, that's the entire problem: waiting for either rent, RE or both markets to drop to a point they can save.

I wonder what this changelog entry means:

> Add support for SDRAM

Surely it had support for SDRAM before, since DDR, DDR2, ... are all SDRAM.

Edit: I figured it out. The JEDEC SPD spec calls SPD type 4 "SDRAM", referring to Single Data Rate SDRAM.

The article mentions pigs wouldn’t be wandering the village streets, but as a counter example there were the “St Anthony’s pigs” owned by the friars that were legally protected and had free run of the city. Dante alludes to these in Paradiso, where they took on a metaphor of some friars’ greed.

There seems to be a fundamental problem with the logic here. It is asserted that because the COVID pandemic had a huge impact that the cause must be investigated, but if the origin was zoonotic then the origin may remain ambiguous and even if understood there may be no effective way to respond. That is, there may be multiple species functioning as reservoirs in the wild and no way to know for certain and no obvious way to eliminate contact with humans. It seems that the desire for a cause that can be handled with a simple response is leading to this conclusion.
how unexpected!
If all the landlords in an area use this and discover that the real market rate for rent is double, what is different from them doing this independent of each other and independent of this software? Does this not simply enable price discovery to occur at a faster pace?
> How do manufacturers throw in all the crapware and expect a good user experience and happy customers? Oh of course, they don't care.

Edit: To be clear I'm not defending the companies, they shouldn't put all this crapware on there. I'm just saying most customers won't notice it on a new laptop.

In most cases on new laptops their crapware doesn't make a huge difference, because there is enough CPU headroom. The people who are doing so much that they would notice probably will reinstall fresh Windows anyway.

The problem here was that it was a used laptop.
I noticed it in my grandmother's backyard, so that variable was controlled. Then I noticed it pretty much in all my old haunts. Sample size N = 1, etc.

This is kinda cool, but also falls apart at airplane scale:

I was recently on a flight, and had neglected to pair my AirPods Pro to my Steam Deck before takeoff. I put my AirPods in pairing mode, and I saw the familiar AirPods pairing pop up on everyone's iPhones and iPads around me — someone nearby (that I didn't see) of course hit connect to pair my AirPods to their device.

After a few more failed attempts, I gave up, AirPods left unpaired (to my devices). My husband thought it was hilarious.
Wasn't "dense pack" the scaled version? The previous concept was to just build huge fields of silos that were mostly empty I thought.
At least BigQuery does a fair bit of typechecking, and gives error messages in a way that's to the par of application programming (e.g. not letting you pass a timestamp to a DATE function and stating that there's no matching signature).

But a tool that doesn't "require" bad practices but doesn't require good practices either makes your work harder in the long run.

Tooling is poor, the best IDE-similes you got until recently were of the type that connects to a live environment but doesn't tie to your codebase, and encourages you to put your code directly on the database rather than version control, the problems of developing with a REPL and little in the way to mitigate them. I'm talking of course of the problem of having view and function definitions live in the database with no tools to statically navigate the code.

Testing used to be completely hand rolled if anyone bothered with it at all.

That was until now, that data pipeline orchestration tools exist and let you navigate the pipeline as a dependency graph, a marked improvement, but until dbt's Python version is ready for production, we're talking here of a graph of Jinja templates and YAML definitions, with modest support for unit testing.

Dataform is a bit better but virtually unknown and was greatly hindered by the Google acquisition.

Functions have always been clunky and still are.

RDDs and then, to a lesser extent, Dataframes offered a much stronger programming model, but they were still subject to a lack of programming discipline from data engineers in many shops. The results of that, however, are on a different scale with undisciplined SQL programming, and it's downright hard to be disciplined when using it.

The trend to move from ETL to ELT I feel shouldn't have been unquestioningly transitioned to untyped Dataframes and then SQL.
Except if we have a negative leap second at some point

I had a similar experience. (Turkey legs are delicious, BTW.)

I suspect the turkey was quickly introduced as a domesticated bird in Europe shortly after contact with the Americas.

Otherwise, the turkey may be the closest cost-sensitive equivalent of whatever bird people at a lot of back then. Maybe it was a goose?
100% this. Spinning up a new Next project "just works" for getting started, and makes me confident in a scaling path as times goes on. Adding things like lightweight API routes (weirdly useful in a ton of situations) or pulling in interactivity are trivial.

I still write static HTML if I'm positive it'll be a forever fit - but anything client facing or with an ambiguous feature I reach for Next.
On an extended visit to a small village in Mexico where the pigs would wander, I made a sport of stalking the piglets and attempting to pick them up. I achieved my aim once and the mother sow came charging at me & thereby convinced me to yield up the piglet toot suite. No mauling ensued thank goodness.
There's a famous old ad where someone put an ad in the newspaper that said "Learn how to make money, send $10 to XXXX". Sending the $10 in got you a letter that said: "place an ad in the newspaper that says "Learn how to make money, sent $10 to [your address]."
Some human desires are more predictable. You can ground out some value in basic human needs: food, clothing, shelter. They imply land value (for example, agricultural land) and energy usage (heat, transport, production) though not in a straightforward way. And various security measures can be valuable because any of the above could be taken away.

This doesn't imply stable prices, though. Far from it!
There are a variety of different approaches to counter the ABM and ragged second strike scenario, China is investing in several.

* Just build more nukes. Adding more warheads, especially ground-launched ones, is cheaper than adding more interceptors to the ABM shield, so it's always a losing game. Thankfully, no one seems to be pursuing this route, since that is massively destabilizing.

* Make it harder to take out all of your missiles in a first strike. Your link is an excellent example of this. Building additional silos is even cheaper than building additional missiles, and then you can play a shell game where you don't know which silo houses a missile and which does not so you have to strike at them all. There are other basing options available, like road-mobile launchers, which China and Russia have both invested in, though this is easier with shorter range ballistic missiles. And of course there are ballistic missile submarines, which give most survivable second-strike capability, but are much more expensive to operate.

* Use a delivery system that is harder to intercept, which I mentioned before. China has tested using both hypersonic glide vehicles and fractional orbital bombardment, in fact both at the same time (https://www.armscontrolwonk.com/archive/1213655/a-fractional... ).
