Part of the solution is at the level of attitude, just one more productive than "don't fuck up"

To create a contrived example, say someone reads your note on replacing bash scripts and decides they agree with the principle.

They go into work tomorrow, their fellow engineer agrees on the technical merit, and they reimplement a bunch of bash scripts in Rust with a suite of tests bigger than anyone imagined, and life is great.

... fast forward a few months from now and suddenly a state the bash scripts were hiding flares up and everyone is lost, and type safety didn't help.

A shared culture of "conservation of value" can help in a lot of ways there. That's the attitude that creation of value is always uncertain, so you prioritize potential future value lower than currently provided value:

- instead of looking at technical merit of the new, we prioritize asking: What specific shortcomings the old way have? What can we improve downstream so that the value those systems provide is protected from invalid states we're worried about this tool generating?

- does switching the language reduce the number of people who can work on it? Do we reduce the effect surface area of the team providing value to it? When hair is on fire do we know the sysops guy won't balk?

- when it goes down, with a culture of "conservation of value", your plan A is always rolling back, there's no back and forth on if we can just roll this one fix. If you cause the company to lose a million dollar trade, it's already codified that you made the right decision

Obviously these are all extensions of a contrived example, but to me culture is heavily utilized as a way to guide better engineering.

I think these days people tend to think in terms of culture that affirms, as a reaction to cultures that block anyone from accomplishing anything: to me a good engineering culture is one that clashes with what people want to do just enough to be mildly annoying.
Ben notes that Kernighan regrets the way local variables are handled in Awk.

I patched GNU Awk to have a @let extension that gives you scoped locals (usable in functions as well as in BEGIN/END blocks):

$ egawk 'BEGIN { x = 3; print x; @let (x = 4, y) { print x } print x }'
3
4
3

@ is used because there is at least one other existing extension which is like that: @include.

https://www.kylheku.com/cgit/egawk/about/

This was rejected by the GNU Awk project, though. I was encouraged to make a fork and give it some kind of different name, so I did that.
Hold on. Are we blaming the plane crash on the pilot here? It seems there is so much other stuff wrong with this company first that such a deployment would tank it.

No kill switch. Literally needs to be a power switch and a trader who runs to the room and flips it. Ridiculously small amount of cash for the trading volume, and no way to borrow more to stay in business (but that borrowing requiring manual intervention no accessible to the trading system). Obviously the decision to leave that code in there, and for there to be config setting to bring it back.

Then the devops stuff - rollback plans, approvals, pairing on deployments, etc.
Nope, nothing to do with that. The difference is: older style have either the compressor either on or off. They turn on or off using a contactor (basically a special relay).

Inverter refers to the drive circuitry for the compressor. The inverter basically concerts AC to DC, then it's inverted back into AC, however the AC output can be variable frequency. This allows for slower speeds of the compressor, at lower power consumption.

As far as I'm aware the compressor design can be exactly the same, the only difference is the drive for it.
Just run the tap at the kitchen sink until the water gets as hot as possible, then start the dishwasher. It'll get nice hot water straight from the pipe that way!
> I guess this arises from the fact that much of the profit for HMOs is coming not from our monthly fees but from those extra charges.

At that point it's not an HMO anymore and basically becomes a single-provider PPO with an added subscription fee.

> this incentivized insurers to increase dollar margins by growing revenue (and focusing less on costs) and to transfer profits from the regulated insurance side of the business to the unregulated provider side (see UNH and Optum).

Pretty much.

I had an old Bosch dishwasher with a pre-heater and a macerator. It heated the water hotter than modern ones. What I noticed was there was no need to prewash dishes. Slob roommate left spaghetti sauce in a pan all week while you were gone. Dishwater would strip that right off.

If you compare the energy efficiency of my old one with a new ones where you have to pre-wash your dishes with warm water the old Bosch wins both in energy and water use.
I suppose it's impossible to prove the specifics of the conspiracy, but that Jack Ruby, a guy running strip clubs for the mafia, takes it upon himself to publically shoot Lee Harvey Oswald kind of proves to me that there was some kind of conspiracy. What other explanation could there possibly be? What Oswald might have said if we were kept alive... no one will ever know. But if there was nothing there, why did Jack Ruby kill him? Temporary insanity, deeply patriotic fan of JFK, or tying up loose ends on orders -- what makes more sense?

You'll need to measure the amount of water you use in the process. Modern Energy Star-compliant models use less than 4 gallons per load. And don't forget to wash the same number of dishes as a full dishwasher load!
I do the dishes one load at a time (wait for the dishwasher to fill up so I’m not running it empty) and let my European-make dishwasher run overnight when electricity is cheapest and cleanest. But laundry requires being hung or transferred to the dryer immediately after to avoid things getting stinky - and I usually have multiple sorted loads (whites, colors, delicates) that I can’t just throw all together so I actually do get annoyed at how slow my front-loading washing machine is.
Hope you never eat anything with, among other things, onions or garlic.

Climate change and global warming aren't the only problems with gasoline cars.

Just listen to how the news and the average person discuss gas prices. Operating gasoline vehicles requires continuous access to affordably extracted oil. The US is so car-dependent that high gas prices in isolation can impact the economy.

EVs open options and almost certainly stabilize energy pricing more than refined gasoline. They also use less energy overall.

Iceland has incredible hydropower resources, and aluminum is the primary way they export their excess energy: https://en.wikipedia.org/wiki/Economy_of_Iceland#Aluminium

Sibling comment mentions, correctly, that these things need to be running at full utilization for a long time to make sense. So, you'd need batteries to smooth wind or solar, which is still economical (and will become increasingly so).

That article snippet doesn't fully do it justice. They sell electricity to aluminum smelters at 1/4th the price of the EU, and a surprisingly large portion of their total energy consumption is industrial.

Iceland has done it correctly, though, in that in order to tap into their natural resources, you need to be an Icelandic company investing in Iceland. Some want to build a cable to Iceland to help the European electricity market, even though it's never been done at that length before. Some in Iceland are (rightly!) worried that would increase demand for hydropower and further industrialize Iceland, etc.
Either your dishwasher isn't very good or you aren't using it properly. You should be using powder in both boxes so the prewash cycle and the main cycle can work [1]. Pods? Waste of money!

> Veilid is an open-source, peer-to-peer, mobile-first networked application framework, with a flagship secure messaging application named VeilidChat. Veilid is conceptually similar to IPFS + Tor, but faster and designed from the ground-up to provide all services over a privately routed network. The network also enables development of distributed applications without a 'blockchain' or a 'transactional layer' at their base. Veilid can be included as part of user-facing applications or run as a standalone server for power users who wish to help build the network.

I used mine for the past month or two to track my activity and plan my weight loss - it's been surprisingly accurate.

Define conspiracy theory. The Deep State involving every government man at the time? Most likely no. A few people? Possibly. Not just Oswald? Probably. Oswald not involved at all? Unlikely, but possible. There are degrees of probability and likelyhood.
Sure, the dishwasher takes a few hours, but it's rare I'm ever actually waiting on it. Load over the day, run in the evening after dinner, clean dishes ready to unload either right before bed or in the morning. The loading/unloading is much faster and easier than actually washing by hand, and it's more efficient than what I'd do by hand.
HMOs are so much better than PPOs, but they're rare these days. They are significantly cheaper than PPOs. Most HMOs don't have deductibles, and all of them have lower premiums than PPOs. The "out of network" coverage of PPOs is an irrelevant scam. Your insurer covering 10% of a $200,000 out of network surgery is still going to bankrupt 99% of people in America.

HMOs require you to get a referral from your primary care doctor to see a specialist, which has the added benefit of making sure people actually have a PCP. Primary care is one of the few types of care where the more you apply it, the better a patient's health outcome.

No one gets an HMO because they're scared of having less choice of which doctors they can see. They pay more to have a choice that's ultimately irrelevant to their health. Most people choose doctors based on friend/family referrals and Yelp reviews, meaning they don't know how to choose a doctor. Reviews/referrals have no relation to health outcomes.

The end of the article refers to the "medical loss ratio" enforced by the ACA, which did indeed incentivize insurance carriers to tolerate higher healthcare bills. This affects PPOs much worse than HMOs. It should all be burnt down.

Kudos for having an interesting take. I assume you already live by these rules you’d set for others? If so, you have my respect. Not my vote though, I travel frequently and far for both pleasure and business.
Maybe it’s your dishwasher or you are not putting powder in the pre-rinse compartment in addition to the action pack or powder in the main compartment. It doesn’t matter how old or baked-on the food residue is, and it can be baked-on cheese, egg, meat, burned gravy, whatever and it’ll reliably come off in the (European) dishwasher each time, every time.

Even when I was in a rental with a crappy American unit from the 80s, it would still get everything though I often had to use the extended “pots and pans” cycles for that to happen.

But yes, utensils can and do corrode in the dishwasher over time if you have different metals thrown together in the high-temp, high-conductivity alkaline bath.

How is the water 'consumed'? I see that in the article that they say that they only draw water in on hot days, but what happens to it after? Surely they can't hold onto all of it. Is it just discharged, but a bit warmer? Wouldn't it at worst just be pumped out to a holding pond until it's cooled enough to release it back into the water supply?

but does US maintain a world hegemony? How does it demonstrate hegemony?
Ok, I'll agree that you CAN do it. However, outside of camping, I don't think I've ever seen someone actually do that. But, I'll concede that. My dishwasher uses 3.15 gallons on a normal wash cycle, which I don't feel too bad about.

Finally! It’s been days if not weeks since the last social app was released. People suffer every day from having too unified friend graphs, and this brings some well needed fragmentation in the app silos we all love. I can’t wait to build another incomplete social graph of a slightly different demographic.

It’s also incredibly refreshing to see marketing for “personal chats with friends” combined with not a single mention of outdated fads like “privacy” and “encryption”. This leaves the door open for data collection of intimate relationships – an underrepresented data source in todays ad targeting frameworks.

You separate your dishes by color when washing them?
Kaiser is primarily a California HMO (they have a few other plans). It has been around for decade. People either hate it or love it because it is quite rigid in how it works (and you have to go specifically to their facilities). For the majority it seems like it's a cheap but very rigid option (especially compared to PPOs).

I feel like, at least in California, the majority of HMOs got usurped by HSAs which became popular after Obama-care kicked in. Many many companies used the threat of the never implemented "cadillac plan" tax to rework the benefits they offered. It wasn't unusual to have a couple both have different PPOs and effectively get improved coverage through "double coverage". It's still possible, but not with HSAs.
One thing we can probably agree on is that those centralized test centers were the dumbest idea of the entire pandemic. For the same reasons you state, they always seemed absolutely insane to me.

Diesel truck emissions have been reduced by 90% since 2000. Unfortunately some people have a burning desire to roll coal and they cut off the DPF and reprogram the computer with a "tune" to dump more fuel during the combustion cycle. All of this of course kills fuel economy and power but they feel the power band shift and think it helped...and they get to blow black smoke on people. So if you see someone rolling coal, know that they modified their truck on purpose to do that.
For container ships, engines that burn hydrogen derived ammonia, are more viable than electric to power these ships because of the long distances and the cubic area that ammonia storage would take to travel those distances is dramatically less than batteries. Man Energy Solutions is the farthest along with the engineering on these container ship engines and even has large scale commercial orders[1]. Ammonia has problems in that it is toxic and can produce NO2 if burned inefficiently. However, the relatively high energy density, ability to quickly refuel, and lack of need for pressurization is a huge benefit over electric.

Perhaps rare in the general population, but the entire military is functionally an HMO (as are the dependents, unless specifically opted into the PPO option, which is rare).

I just swapped to the PPO version after retiring because the cost isn't any different, and I'm no longer in the area of the easy HMO's for them (Military Treatment Facilities).

Wild west times ! It's worth noting, that things changed a lot in trading systems since then.

When I started working in this domain (2009), it was pretty crazy how unreliable those systems were, on all sides - banks, brokers, exchanges. Frequently you needed to make sure over the phone, what quantities got executed etc.

I remember when the Italian exchange was rolling out their systems, at some point we did "tests" on a mix of production and UAT - if my memory is correct, we were just changing IPs to which to connect for order passing to test for the upcoming release, after the market closed. We couldn't just test in their UAT environment, since it was so bugged and half down most of the time.

And let's not even talk about Excel spreadsheets with some VBA code that would make chatGPT swear, that were pricing instruments with volumes traded with a lot of zeros.

It's very different nowadays, in part thanks to stories like this one. Most things are automated, and there is much less cowboy's attitude.

There are mandatory kill switches, a lot of layers of risk / trading activity monitorings (on your side, on exchange side), and really a lot of hard learned lessons incorporated into the systems. That's also part of the reason why people sometime tend to be naive about how hard it is to build a good trading system - the strategies are sometimes now really smart - it's mostly about how to avoid getting killed by something that's outside of usual conditions.
Ouch… Now I feel dumb.
I disagree, HMOs can be severely limiting especially as medical practioners (and medical groups) change or cancel insurance groups (HMO providers) they partner with. Further, getting access to specialists can be daunting - in network may be over loaded/over booked (appointment in 6-9 months); out of network providers can take significant hoops to jump through.
I feel like it's a mistake to consider mobile games as being part of the same market as PC/console games.

Sure they're both "games" but I don't know that they're competing for the same set of users - either people play one or the other, or the people that do crossover in both markets are probably playing PC/console games at home and mobile games on the bus or train.
