> OKR mostly aims at developers

Ops can totally have OKRs. Fewer incidents, faster resolution, faster deploy times, longer log retention, decreased AWS spend, the list of objectives I can think of off the top of my head is quite long.

Same for project managers: on time projects and reporting, better estimates, faster issue triage, more a/b experiments, more features launched.

OKRs done well are effectively a method of improving KPIs by recursively breaking work up into subtasks.
CEOs are counterparties in the drug trade, too.

Everyone uses cash for some transactions, mostly because it affords privacy.

I'm wondering if remote-first and work from home will end up being reverse-ageist. Developers and others with deep existing networks and a lot of experience may do just fine or even thrive, while the young may struggle to develop those networks in the first place.

I read 'duration' as the charge/discharge cycle time rather than the battery's lifetime in number of cycles. Clearly the more cycles a battery can handle the more cost effective it will be (more cycles over which to amortize the capital cost) but you still have to pay interest so even if the battery can handle infinite cycles if you only cycle it once a year (to balance seasonal differences in generation capacity) it will probably not be cost effective.

I think stationary storage batteries are great, but only for short duration storage (1 day) rather than long duration storage (months).

> If the price is too high, then no one will purchase it. Therefore, Gilead makes no money.

This is great in theory but is entirely inapplicable and utter non-sense in practice in a health care context, and in this instance in particular. My original commend made mention of inelasticity of demand. When people's lives are at risk, there is no demand curve and equilibrium. The price is what the supplier says it is. It has nothing to do with what the market will bear, or whatever other macro 101 theoretical framework you're applying to this reality.

It's different in almost every possible way than say, going to the grocery store and deciding if a box of cookies is too expensive for the value you're deriving, and whether this alternative or that alternative is a better value.

Maybe you don't know much about how billing and payments in the health care system works, or the exorbitant costs for things that happen in a hospital setting that are completely untethered to what anyone would be willing to pay in a normal market.

> Obviously, Gilead wants to make money. So they will decrease the price to attract customers, ultimately finding a ideal price that maximizes the balance between profit margin and customer volume.

Again, this isn't a b-school case study. Your mental model doesn't apply here.
Drug dealers are not 100% analog. The further up the chain you go, the more analog it gets though.

It does and it's important and I'm not suggesting people purposely ignore it, I just don't know how you get to the point where it's saturated your social feeds so much that you get this kind of phenomenon. I get a lot of news or people posting political commentary, which I enjoy seeing, but it's also mixed in with a lot of music or design or game dev stuff or whatever.

Like another comment here mentioned, the diversity of content (and maybe slightly less political news) is why people like HN, so maybe I've just been lucky to be able to 'curate' my Twitter similarly.
When was the last time Hollywood made a major movie about the Tiennamen Square protests? Or the Chinese war against Tibetan autonomy?

Notice how in Top Gun 2, the Taiwanese regalia had been removed.

American elites have no problem censoring American citizens (in America) to appease Chinese elites.

This has been going on for a very long time. What’s different is people are realizing it.
The commercial grade machines I've dealt with in SF apartment and condo buildings were worse overall than the non-commercial ones in Victorians and townhomes. They could take larger loads and washed/dried faster, but they had worse sensors, distributed detergent worse, ran too hot for drying, and slightly damaged some of my clothes.

Hi, author here. Thank you so much for this unfudging! I knew I was fudging things up a bit, and I didn't really understand the relationships between Prolog, Datalog, Horn clauses, and first-order logic. This clears things up a lot, though I think I'll need to read it a couple more times for it to sink in! Thanks again.

> I don't understand what this means

Suppose you have ten people and the money supply is a hundred dollars, of which each person has ten. And then suppose you print ten more dollars and give them all to person #10, so that person now has 20 dollars. That is equivalent, economically, to keeping the money supply the same but taking 91 cents from each of the other 9 people and giving it to person #10: in both cases, person #10 now has 2/11 of the total money supply, and persons #1 through #9 each have 1/11. And that means their respective fractions of the total buying power have changed the same way, since the buying power of money is the fraction of the total money supply that that money is equal to. So person #10 can now buy more of the things he wants, and everyone else can buy less.

In the case of the Federal Reserve printing money under normal circumstances, person #10 is financial institutions and persons #1 through #9 are everybody else.

> Aren't the victims you are imagining the hypothetical people who have large amounts of money in checking, savings, or literally under their mattress?

The "victims" are everybody who isn't getting some of the printed money. The fact that they already have other money doesn't change the fact that they lose buying power. Nor does it matter where their other money is stored. It could even be in assets like a 401k; as long as the assets are denominated in money (your 401k balance is in dollars), the buying power they represent is affected.

> I really didn't think that was a significant segment of the population.

Everybody who doesn't get new money the Federal Reserve prints under normal circumstances is almost all of the population.

> It seems like the overall goal is to provide some intuition for how automatic differentiation & program synthesis might be implemented efficiently using matrices.

Right! I wish I had emphasized that theme a little more. This is basically a long digression on how to think about automatic differentiation in the context of program synthesis, two topics which I enjoy thinking about.

> However, I'm a little confused on how the section on Weifeiler-Lehman & checking for isomorphic graphs ties in to the rest of the article?

Great question! I introduce isomorphism testing for two reasons:

1. It is an example of a general purpose algorithm which, although we do not show it, can be implemented completely using matrix multiplication.

2. It is an example of how message passing on graphs works. This helps us build an intuition for how to implement more complex graph algorithms.

Hamilton (2020), does a much better job at introducing the WL algorithm and why it matters in the context of graph representation learning:

It's not the architecture, it's the representing all the states in prod in testing.

Not saying it's impossible, just not always feasible to have it actively "perfect".

I've found that an "ok" testing envrionment and solid unit testing / monitoring tends to do better.

> Put briefly: give a rational agent more than one thing to do, and they will only do the most profitable thing for them to do. To avoid this problem you need perfectly equal compensation of their alternatives, but that's flawed too, because you rarely want an agent to divide their time exactly into equal shares.

I would argue the system is working as intended. Contrary to your assertions, you don't want employees spreading effort like peanut butter, you want to focus them on executing one or two things quickly and getting value out of that quickly. Instead of launching 12 features a year from now, I'd rather launch 1 feature a month.

> you cannot improve a process that you have not first measured and then stablised.

There is of course, a certain amount of reasoning under uncertainty involved. One of the lessons many folks learn from a/b testing and OKRs is just how hard it is to actually make a difference, and folks need practice calibrating.
Ask HN: New Leadership Job Advice
I've been in either a senior or tech lead position for quite a number of years. I've recently been offered a job in a leadership position (head of x). I know I've done all of the individual parts of this job in the past, some of them together, some separately, and I'm pretty nervous / excited to start it.

I'm really interested in any advice on how to play this role, and especially how to be effective at it during remote work. Thanks.
this is much better than previous things i've seen that implanted electrodes in the brains of cockroaches and used electrical impulses to steer them around.
Thanks for being on this thread here and elsewhere, I forgot to check replies for awhile.

I agree completely. If anything they need to do what the deaf/Deaf community does and actually brand as a capital-g Gamer.

Remember the whole point of this post is that the military is using games to recruit kids.

It does not matter if they are a Gamer or a gamer in that case because it doesn't matter.

The military will be on Twitch or running real-life fire team tactics in COD Warzone and it doesn't matter anymore. Gamer or gamer they will reach some kids, some of which will be fit enough to join.
It’s close to impossible to stop misinformation given most westerners Have a much higher trust level of their media E.g Fox News reporting hospitals are getting paid to attribute deaths to Covid-19 regardless of the cause. I’m sure many on the right-wing actually believes it. And also this forum is of western mainstream view and Values so bias is expected. dang teaches a good lesson in how to live here so nowadays I rarely get triggered
I don't think I know of a company that has really nailed being well run at scale, I can maybe think of a few that I don't want to name but they aren't in tech anyway.

My guess:

Tha article states that closure of bank premises is driving the shortage. You can get new coins at banks. You can't get coins from ATMs or grocery store cash-back.
Since there seems to be a lot of hate for the Nespresso, I'll chime in:

I currently have a Nespresso, Aeropress, V60, a few Moka pots, and probably a couple other devices I've forgotten about.

The Nespresso is super convenient and not bad tasting, but I put sugar in my espresso - a grave sin according to coffee snobs in America - so ymmv.

Sometimes I want a shot of coffee but don't want to wait for the Moka pot. Yes a Moka pot is convenient - versus an actual espresso machine - but it's lightyears away from the Nespresso in that respect.
Spot on. Coffee is much tastier freshly ground.

Try roasting your own beans. It’s fun and you can do it on the stove with a pan. It’s quick too.
We all agree that it would be wrong to poison the reservoir. We all agree it’s wrong to pool our money to hire someone to poison the reservoir.

If I vote for the mayoral candidate who promises to poison the reservoir, why should that suddenly be a completely morality-free decision on my part? Just because a lot of people made the same decision I did?
> my point is that our system incentivizes the wrong things - namely financial asset speculation and wealth extraction over real work

The actions of the Federal Reserve over the past three decades have contributed to these incentives. We’ve experienced plentiful supply of money during a period when productivity gains have kept consumer prices low, so money has flowed toward a steady upward pressure on asset prices and a golden age for asset owners.
Banks I used back in the midwest growing up always had change machines and it was a routine to bring in our change whenever the container got full, they'd turn it into cash or deposit it free of charge.

It seems way less common in CA, at least according to my experience.
That’s... not even true at all.
Pro tip: Coinstar wont take a cut if you get it as a gift card. The times I've used them I just opt for an Amazon Gift card or one for the local grocery chain that I'm already going to be spending money at.
As a percent it was a great return, but as an absolute number it's rather poor. How long did the whole process take her (including collecting the coins and getting to the bank)? Half an hour? Longer?

There's just not enough money in that to be worth it.

If ever there was a time when ethics is need in engineering decisions, it's now (for years, I've preached that ethics ought to be part of engineering courses).

In various posts years ago I predicted that this spying/privacy scenario wound happen comparatively soon, now it has happened. I then said to the effect that how is 'security' going to check every bug or fly that flies into a military research establishment and sits on a loaf of bread in the staff canteen and then proceeds to listen to scientists discussing secret info.

It's bloody nightmare I recon, and methinks it'll only get much worse. Heavens knows where the endpoint of this is likely to be.
> I’d like to see statistics on how often people use analog money.

Probably heavily skewed right now compared to normal. As of a week ago, my grocery store does not accept cash (at least at the self-serve lanes, which seem to take about 1/3 of customers) because they don't have the coins to make change.

If you had told me 25 years ago that in my home country (Bangladesh) people were going to be demanding removal of a statue of lady justice from in front of the Supreme Court, and that the court would oblige, and that veiling women would go from being nearly non-existent to commonplace, and that secular journalists would be getting murdered, I wouldn’t have believed you. But Islamists got control of education, and all of those things happened.

So imagine my alarm to read that 20% of social science professors self-identify as Marxist. A third of college students embrace communism. In 2017, the nation’s premier newspaper ran a sympathetic retrospective on a century of communism. Thousands of school districts are integrating material into their curriculum that claims slavery was capitalist. A bunch of people on a website associated with a startup incubator are going to read the preceding sentence and go “yeah, that makes sense.” So it feels like gaslighting for you to say it’s a “problem that doesn’t exist.” Maybe I’m being paranoid, but in my experience civilization is fragile. Better safe than sorry.

But obviously, ranting about it on HN won’t fix the problem.
> How long did it take the Democrats to accept their loss?

It took 0 days. The election was on Nov 8, 2016, and Clinton conceded on Nov 9, 2016.

Trump still falsely claims election fraud to this day because he lost the popular vote.

Trump's historically-low approval rating and polls (including conservative polls, like Rasmussen) disagree.

No, they had a narrative they wanted to push: "right-wing attackers victimize noble protesters", and since there were only a few examples available, they had to pull stories and footage from the many instances of when protesters attacked vehicles.

I don't know you personally, but if you're like 99% of left-leaning urban professionals, you're not aware of those instances, because you're only exposed to a portion of what's happening. I'd suggest following a broad spectrum of people on social media from the left, center, and right. You'll be surprised what the mainstream left media leaves out.

Right-wing media does the same thing, by the way. You really have to watch both to give anything resembling reality. It's a big problem, and it's getting worse.

Even (decidedly left-wing) Brian Stelter featured this problem on this week's Reliable Sources on CNN. For example, mainstream media is happy to cover what they view as the malfeasance of the federal law enforcement officers in Portland, but they fail to show the acts of the rioters that played a role in their deployment (burning buildings, destruction of property, menacing cars, etc). To be clear, I personally think their deployment was probably unwise, and that politics played a large role. However, Portland's mayor has consistently refused to crack down on whatever label you want to put on the violent protesters wearing black. That adds significant complexity to the situation.

NPR was the most neutral of any major news organization up until the past 2-3 years, when they've undergone major changes and now put out mostly ideologically-driven pieces like other outlets on the left.

I do give credit to many local media outlets, who are often the only ones asking the hard questions, like this local outlet in Portland:

That's not true in the slightest. Energy per instruction varies a lot but has not decreased that much on recent nodes. The resistance growth just outpaces the shrinking capacitance of the gates.

On top of that processors are faster, applications and sites are hugely more intensive to render, and the hardware (mainly antennas) suck up much more energy.
