> if I reuse or recycle something

Reuse, sure, but I doubt you have the equipment required to recycle paper, glass, metals, plastic, etc. If you did, I'm sure you'd know that equipment was probably pretty expensive to purchase, and far from free to operate.

> Or recycle crates by using them as decorations.

That's not really "recycling", that's just another form of reuse.

> it's being used multiple times reducing the cost.

That's if it's being reused. Most people don't reuse all that much of what they consume. Think soda cans or bottles, jars of peanut butter or jams, plastic laundry detergent containers, paper or plastic grocery bags, etc. Most of that ends up being thrown away after being used once.

It's great when people reuse those things over and over after their initial use, but the reality is that very few people actually do so.

All of this is why very little of the plastic we toss in recycling bins actually gets recycled. It's just not economically feasible to recycle all that plastic. For decades now we've shipped all of it overseas, but a lot of those places have stopped taking our plastic, because they don't want it either.
Always was, I think?

At least for domestic uses, I know nothing about fancy alloys.

Even when I was a kid, people were big on separating steel and aluminium cans and showing off how recyclable aluminium is.

yes I can kind of see that, its not specific enough and almost a product recommendation ask. Normally the Security department handles this and we turn it over to them to make the policies and procedures.
Folks are going to have strong opinions here about things, so I'll try to stick to my personal experience. I adopted 1Password at my current organization. Overall, I've been very satisfied with it. Here are the major points I've noticed:

* Great authenticator support. We have some accounts that our team members have to share, and we want MFA on those accounts. I can add an MFA field to 1Password entry and the people who have access to that entry can use it. Doesn't help when those entries require phone/e-mail based MFA; I'm working on a little Twilio / outlook group setup to take care of that.
* Easy to navigate group membership. Passwords are stored in vaults and individuals or groups can be given access to those vaults. The model for it fits in my head and I like that.
* Easy share ability. There are a few credentials that I occasionally need to share outside of a vault. I can create a link and grant access to specific individuals for a given amount of time.
* The browser extension and integration have been really smooth in my opinion.
* I find tagging and taxonomies of tags to be helpful, and 1Password supports those well.
* We've gotten some great mileage out of 1Password connect. Some of our infrastructure secrets now reside directly in 1Password, and 1PW connect pushes them into our k8s environment as secrets where our apps can refer to them. Makes secret management across environments that much easier.
* SCIM support (which I haven't yet implemented) and SSO support to bring more convenience for end-users.
* Easy ability to recover if an employee forgets their master PW (have done this a handful of times).
* A nice perk: our 1PW business comes with a free 1PW personal subscription for people, completely separate. If the employee leaves they have can convert their personal vault to a paid subscription or export it.

To answer your questions specifically based on my current context:

> What are the recommended ways to store and give access to passwords?

1Password vaults. One vault per style of responsibility. 1+ groups have access to a vault. People get put into 1+ groups.

> How can a new hire be given access to all required passwords day 1?

In our case, day 1 they accept the 1PW invite in their inbox, and then we assign them to groups. Done.

> And when such new hire gets promoted, how can we give access to the additional passwords they will need?

Keep those "tiers" of passwords in separate vaults. Update the groups when someone's role changes.

> And if someone leaves the company, how can we change only the sensible passwords they had access to and preferably notify everyone with access to it that it was changed?

See what groups that person is in and what vaults they had access to. Review "high priority" items which you've tagged in such a way as to surface them. Send an e-mail to the members of the vault telling them you're rotating passwords. Rotate the passwords. Anyone who's a vault member can see the password history too, I believe, so if something goes wrong the old password will still be available.
that's surprising to me. Torch supports ROCm, why are startups wasting their money on H100s if they can get a better deal with AMD GPUs?

Harvard Math: Learning by teaching Chatbots [video]
I'm pretty sure they are taught this. There's a different between taught and having an in-depth understanding of what makes a good experiment.
I stopped recycling plastic when it became clear that 70% of the collected plastic was being burned just like the regular trash. The only things I will recycle are PET bottles, glass, aluminum cans and paper.

At the start of this year my municipality recognized that collecting plastics separately was simply a net loss environmentally and economically and removed all plastic waste containers (except for PET). Instead they will now simply try to recover some of the useful plastics for recycling from the mixed trash and burn the rest with the trash.

When the plastic recycling stream contains 70% trash that you can't use, then recovering the 30% from the plastic recycling stream is barely more economical than recovering that from the mixed trash stream.
Oh, I mean, the most obvious problem with that idea is there’s no way to ensure that whenever you update your weights that they will still satisfy those constraints.

This idea has been well studied in mathematical physics, going back to Poincaré, where you work with Lie groups and Lie group actions on your action space. The reason this works, however, is you get a Lie algebra/Lie algebra action that more-or-less behaves like the tangent bundle so the same basic theory around optimization works.

The main problem is they’re generalizing in the wrong direction. Everything still works when you move to Lie groupoids/Lie algebroids. You still get something like a tangent bundle, so ideas like gradient descent or Euler-Lagrange equations still make sense. Thats not the case with a generic monad - in fact the authors don’t seem to acknowledge the fact that there is some work to do regarding compatibility between the monad and derivative to ensure that gradient-based optimization will still make sense.

So, basically, anyone who is familiar with the basics of optimization on manifolds or Lie groups will immediately recognize this approach as hopelessly naive. All they’ve _really_ managed to do is draw some diagrams and say “wouldn’t it be cool if these things were preserved by gradient descent.”
Lego promote the idea of less too. They make durable products and through Lego Replay they will find a good home for your unwanted Lego bricks.
You have to work hard and come up with new ideas better than anyone else in the world, and demonstrate that. Then IEEE asks A review the work of B and B review the work of A for free. If the work is good, IEEE will ask you to transfer your rights to your intellectual property to IEEE, and sometimes pay on top of that too. Of course, you have to pay exorbitant fees to present it. Lastly, you can’t download your own paper from IEEE and must pay IEEE through a subscription or per article. So, IEEE takes your work and sells it back to you. Meanwhile, the access is not open in 2024, and there is a lot of unpaid volunteer activity, typically by local students and academics.

Why? We give you a professional home!

The cost of the online dissemination is minimal, and the events and societies are run mostly by the communities.

Academia always seemed to be a fraud in some ways.
My car only gets 26 miles to the charge, which, believe it or not, is more than enough for my daily use (I live within 5 miles of my work). That being said, I'm not actually convinced that I'm saving money when I look at my electricity cost vs cost of gasoline. Still, the added convenience of just plugging in when I get home and hardly ever having to stop at a gas station is nice.
Ess Ess Oh. Understand the number of individual warm bodies who need access to what. In an ideal world (that may not exist) this should be aligned to job description/contract and the process for when those people are removed under any circumstance. Pay for the users you need on the platforms you use, whether that's cloud or resources for on-prem/locally managed tools. Elevate legacy systems that aren't implemented for the scale you're operating at to be managed safely on a per-user level. Tell executives/budget process/whatever/whoever these liabilities exist and need to be covered in budget.

And then, yeah, find a password manager tied into that SSO platform to fill the gaps/enforce policies for users using tools that don't have SSO available.

If Evian sells its water in bottles made of 100% recycled plastic, that means 100% less plastic is entering the environment from Evian bottles than would otherwise.

China has bet on cheap eletric generation with Coal and electric vehicles to decrease their dependence on Oil.
Chinese EVs, for all practical purposes, run on Coal.

Also, let's not forget that prices of chinese EVs benefit from the massive scale economies enabled by years of subsidies and tax credits.
Consumers are not rational. Range anxiety is a thing. And there are some mystical forces pushing weird news about electric vehicles constantly. Popular ones: you’ll freeze in your car in traffic jam in winter. No repair shop can work on electrical vehicles. They burn every other day. And so on.

What Would a Kamala Harris Presidency Mean for Tech Policy?
> ”They're basically stockpiling until the plant is operational.”

Sounds like a variant on the classic tire recycling scam:

1. Lowest bidder wins contract to recycle tires, by offering to do it cheaper than anyone else.

2. Starts storing tires somewhere while they “get up and running”.

3. Discovers it’s cheaper to just keep storing the tires than to actually process them, besides they bid too low to make it viable anyway.

4. Years go by and eventually an enormous tire mountain is discovered (or maybe it catches fire), resulting in big cleanup costs usually paid by taxpayers…
Yeah, this ain't it.

For me getting the task done - produce something valuable - would be more important than trying to validate the usefuleness of some hardware for some edge case that seen unimportant by the vendor (and probably for enough of reasons, considering the inherent and listed above limitations not too vendor specific). When there is a suitable device for that use already, for long.

Good game though for fun.
Hashicorp Vault generally linked up to IDp or One Time Secret (or some service with expiring limited use links).

It’s pretty extendable and can integrate with other engineering use cases, shame about hashicorp license change though. Openbao looks great though as a replacement. These are open source so look no further if that’s what you’re looking for if you want password management, ssh auth, cert issuance, authentication and secret retrieval with k8s for example.
Tesla owner here going on 5 years. I barely scratched 45k miles recently. Battery still can do 300 miles if I want, but I also keep it around 65%. I easily save $1k/year on gas (the app has the estimates). I’ve put on new tires and that’s the only maintenance thus far. I’m bringing her in for body work out of vanity, but it’s not costing me more than $1k with Tesla insurance (ymmv); I’m guessing a body panel and a hood will be replaced.

Sure and actually if available that is the default when mounting ISO. Just saying essentially every PS3 can emulate PS2 games. Not only those with (full or partial) PS2 hardware. Worth mentioning PSN classics (or converted games) utilize software emulation in every PS3.
The Toyota hybrid system is substantially less complex than a typical ICE. there are no belts, no clutch, no alternator, the ICE engine is a direct drive into a planetary gear set splitting power with the traction motor, with the power ratio modulated by a second smaller electric motor

It's basically the best of both worlds, and not at all "two complete drivetrains"
That's exactly what was found and what GP said.
I doubt that’s true. But, I’d be interested in an actual example, if you have one.

Rich folks tend to avoid taxation at all costs, since that tends to be one of the best ways to retain their wealth.
This kind of thing is true outside the context of the head of a company.

I've worked for mid-level leadership in large companies (maybe 1,000 people reporting to them) that basically just cast spells and hope the magic gets done by the people on the ground. I've also worked for leadership at the same level that invests time every month to have skip level conversations 2-3 levels removed in the org chart. There is a material difference, in my experience, in the timeliness and consistency of how things get executed in the latter.

Micro-management isn't always the worst thing. Sometimes it's necessary.
Implementing webhook deliveries is one of those things that's way harder than you would initially imagine. The two things I always look for in systems like this are:

1. Can it handle deliveries to slow on unreliable endpoints? In particular, what happens if the external server is deliberately slow to respond - someone could be trying to crash your system by forcing it to deliver to slow-loading endpoints.

2. How are retries handled? If the server returns a 500, a good webhooks system will queue things up for re-delivery with an exponential backoff and try a few more times before giving up completely.

Point 1. only matters if you are delivering webhooks to untrusted endpoints - systems like GitHub where anyone can sign up for hook deliveries.

2. is more important.

https://github.com/xataio/pgstream/blob/bab0a8e665d37441351c... shows that the HTTP client can be configured with a timeout (which defaults to 10s https://github.com/xataio/pgstream/blob/bab0a8e665d37441351c... )

From looking at https://github.com/xataio/pgstream/blob/bab0a8e665d37441351c... it doesn't look like this system handles retries.

Retrying would definitely be a useful addition. PostgreSQL is a great persistence store for recording failures and retry attempts, so that feature would be a good fit for this system.
This should be a more widely used tactic. It keeps the experience onboard and possibly stops them from consulting for a competitor!

And it's probably better for the individual too. Going from having a role that takes up a huge amount of your life to zero in a short time probably isn't healthy for that person (or their family).
> This famine is the expected result of 20 years of post-colonialist civil war

There are other actors playing here: See the Grain from Ukraine program

https://en.wikipedia.org/wiki/Grain_From_Ukraine_program

"The blockade of Ukrainian ports by the Black Sea Fleet in the first weeks of the invasion interrupted grain exports, rapidly increasing global food prices and fueling food crises, greatly increasing the risk of famine in the poorest countries"

"the Executive Director of the UN World Food Programme, has estimated that the Russian invasion of Ukraine has pushed around 70 million people to the brink of starvation worldwide"

The scope of the program includes Sudan

If you care about money and don't mind making the world a more terrible place: humiliate a few dozen human classical pianists by making them record hundreds of hours of motion capture, invest in engineering a good robo-arm, and I would guess in 5 years you'd have something passable.

“Nobody is textbook anatomy”

I know you’re exaggerating for poetic effect but this might actually be true in some parts of the human anatomy.

For example the description of the anatomy of vessels and anastomoses around the knee…I have had a professor tell me that the standard anatomical descriptions for this might all essentially be fiction. Basically the variation in some of these vessels over there is so high that the standard anatomical textbook description might be wrong.

That being said maybe the professor was wrong. I don’t know. But it was an interesting thing to think about.

I suspect that an electrical car with a range of just 150km using the latest battery technology is already cheaper to manufacture than ICE. But triple the capacity and the cost of extra drivetrain will be cheaper.
just checked https://en.wikipedia.org/wiki/Howard_Hughes , and although Hughes' profile of rich, famous, technically inclined, and clearly eccentric, is an easy comparison, in contrast the only mention that article makes of any mass-market political dabbling on Hughes' part was an insistence on political correctness at post-acquisition RKO.
I got 159 on my first try. I like the art. The difficulty progression is pretty good, starts out easy and gets faster and harder. Nice work!
Same here. It’s not that bad of a solution when you think about it.
Its an interesting optimization problem too: is it better to switch more cars to pure EV, or ensure more miles are driven electric even while hauling around a few gallons of gasoline?

If it's cheaper to get PHEV into more hands, and more commutes are driven on battery power, that may be a better result than trying to subsidize the production of BEVs to outcompete them
I think Paul is pointing at something I've heard described as integrated complexity, basically someone who can hold the entire business in their head and understand how all the problems interact at all levels of abstractions. Not everyone can do this, but the people who can are better served if they exercise the ability because it improves alignment and accountability.

When you assign a person to a problem (hr policy, infrastructure scaling, new UX capability) they will treat that problem as most important, and if then they break it down a certain way and delegate parts those people will do the same with their respective parts. Like a game of telephone eventually what's actually important and what people think is important will drift apart, and before you know it a lot of people are working and doing stuff that doesn't really matter or is even counter productive.

A founder who can hold the whole business in their head and inspects the whole company at all levels continuously will spot and challenge/correct these drifts.

I think it was from Creativity Inc I read that Steve Jobs would challenge engineers about things and if the engineer stood up to him and made their case and it made sense and fit into the vision Steve would commend them and give them the autonomy, at least for that decision/project, but if the engineer folded or couldn't make a case for why it was the right decision he would steamroll them.

So I think founder mode is basically inspecting and challenging the company at all levels to maximize progress towards realizing a vision, and only people who are great visionaries and can also understand and judge the vision-alignment of unlimited micro decisions across many disciplines are able to operate this way.
