I wonder. From first principles, I don't quite understand how cruise ships can be that bad.

It's not obvious to me how tourists on a ship can use much more energy than of they were in a land based resort. Yes, they're moving, but ships move very efficiently, which is why it's used for bulk transport. And tourists on land also move, often by car. Or are cruise ships more comparable to cars than cargo ships in terms of movement?

The facilities themselves, pools, rides, restaurants, A/C, theatres, are all also used on land and I don't the why they would be less efficient on a ship. Unless being on a ship results in trade-offs that impact efficiency, e.g. less insulation requires more A/C. I'd kind of expect the opposite, with everything from cabins to restaurants being comparatively cramped. Maybe energy is just being wasted, what with the power plant being right there.

Obviously the power generation is 100% fossil, but the power on land is also generated somewhere, and it's usually not green -- though this is increasingly an argument.

The crude oil is bad, yes, but also used by cargo ships which must dwarf cruise ships by a ludicrous amount.

The raw sewage is specific to cruises, admittedly, though I'm sure plenty of raw sewage and worse is dumped into our oceans by land dwellers. But that is no defense.

Don't get me wrong, I have no desire to go on a cruise, it sounds like hell to me. I'm perfectly willing to believe they're inefficient, I just don't quite understand why.

The linked study is pretty bad. It seems to get it's data from https://seattlecruisecontrol.org/learn/greenhouse-gas-emissi... which itself is based on website CO2 calculators. That's not exactly science.

Also, a third of the CO2 attributed to the cruise ship vacation is the flight there and back. Which is fair enough if you ask me, just noteworthy and is gonna vary a lot depending on how far people have to fly to get there.
Most of them are our out of bounds memory corruption friends, which everyone keeps telling it is not an issue on their C and C++ code, only happens to others.
hard to smoke sub-millisecond pauses but there may be other axes where it is better. it used to be that people thought azul was better because it was generational but now zgc is as well. my guess is that c4 doesn't have enough of an edge at this point but happy to see benchmarks that prove otherwise.
Brakes are not usually "by-wire" on a car that is able to automatically brake. The brake pedal is still physically connected to the brakes.

Same for the steering. BMW for example has a method where the steering wheel is physically connected but the computer can add corrections to it via a clever set of gears. See here: https://en.wikipedia.org/wiki/Active_steering

If the computer (or electric steering motor) fails the steering wheel still works.
The problem stated was that the marker machine lies 1 out of 15 entries. The paper would contain an incorrect selection occasionally. So, yeah, it would require no one noticing during the act.

> solar rollout I'd happening at insane speeds already

It's kind of not. Solar still represents <4% of generation in the US:

https://www.eia.gov/tools/faqs/faq.php?id=427

The growth rate is high, but that's because the base is low. Moreover, it's barely replacing anything because demand is growing, and will grow even more as transportation and heating have to be electrified. So all the new solar is going to transportation, that's a good fit, but you still need something else to grow to satisfy heating demand, much less satisfy the existing load in the power grid currently being supplied by fossil fuels.

> If sodium-ion becomes a thing it'll explode in production and demand.

The if is the unknown. What if it doesn't, and then we're that many more years behind on building the known alternative that works?

> The speed with which China and others can build factories will make your eyes water.

If it's so fast then why hasn't it already happened? Why is only 4% of production from solar, instead of e.g. 40%? How far do we get on accelerating growth before it flattens out because the low-hanging fruit is picked and the remaining demand is a bad match for solar's generation profile?

> Are you willing to take the economic bet, and spend your billions on nuclear? Or would you rather someone else go down that road, and you make the safer financial choice?

There are plenty of people willing to invest in nuclear. The main problem is that other people (not least of which Russia, who has been caught doing this) keep trying to stop them through anti-nuclear propaganda, lobbying and litigation.

> economically from a capital point of view, the goal is to get a return.

The goal is to stop burning coal.
Their software support (xreal) is very terrible, but most users don't use that anyway; they use it as a normal-ish looking, cheap, fast, long battery big screen. I use it with my s22 ultra in dex mode: it's light, I code/develop with codespaces, termius and vnc. I have very long battery life and it all fits in a little man bag including my foldable keyboard/trackpad. It's the future I use every day.

I am looking to the Viture and others, but so far they are more expensive and not better according to the reviews I have seen. I only care about code and the incidental movie (it's great to put noise cancelling headphone, the protection cap (blocking all light) and just sit in the cinema alone.
FWIW I agree with you 100%, but unfortunately that ship sailed long ago with the horse and barn doors bolted to it, when everyone migrated to Gmail + O365.
> If this is close to cost, is this truly as efficient as it gets?

I saw them hiring Rust devs recently, which makes me feel like they do things efficiently(hopefully). That being said, Serverless is the greed-driven-model, where you start by thinking, "meh, we don't need that many queries/executions/whatever anyways, we will save plenty mulas we'd waste otherwise renting a reserved instance sitting idle most of the time", then something bad happens and you overrun the bill and then go into "sh+t, need to always rent that higher tier, else we risk going bankrupt" and since your stuff is already built, you can no longer change your stuff without another big re-write and fear or breaking things.

I found the ratio of rice and water to be the main issue - and the rice cooker didn't fix that. I stumbled upon a recipe with a different approach that I use now.

Take plenty of water and get it to a boil. Add any amount of rice to the boiling water, and let it boil for 8 minutes. Then drain the water, remove the pot from the stove and put the lid on for a few minutes. Reduces the need for measuring quantities.
> comes armchair experts and the potential for insufferability

Hey, I resemble that remark! I'd be maybe a little less armchair with more surplus equipment access, but maybe no less insufferable.

By all accounts, though, a degree of insufferability is no bar to doing worthwhile work; Socrates, Galileo, Newton, Babbage, and Heaviside were all apparently quite insufferable, perhaps as much so as that homeless guy who yells at you about adrenochrome when you walk by his park encampment. (Don't fall into the trap of thinking it's an advantage, though.) Getting sidetracked by trivialities and delusions is a greater risk. Most people spend their whole lives on it.

As for how little any person can know, you can certainly know more than anyone who lived a century ago: more than Einstein, more than Edison, more than Noether, more than Tesla, more than Gauss. Any one of the hobbies you named will put you in contact with information they never had, and you can draw on a century or more of academic literature they didn't have, thanks to Libgen and Sci-Hub (and thus Bitcoin).

And it's easy to know more than an average doctorate holder; all you have to do is study, but not forget everything you study the way university students do, and not fall into traps like ancient aliens and the like. I mean, you can still do good work if you believe in ancient aliens (Newton and Tesla certainly believed dumber things) but probably not good archeological work.

Don't be discouraged by prejudice against autodidacts. Lagrange, Heaviside, and du Châtelet were autodidacts, and Ptolemy seems to have been as well. And they didn't even have Wikipedia or Debian! Nobody gets a Nobel for passing a lot of exams.

> I think this kind of Excel denigration comes up so often in software forums because we're usually called in to rescue a business when their Excel workflow gets completely unmanageable.

I my uninformed opinion it is because SOP (spreadsheet oriented programming) is as different from other paradigms as Forth is from Java. Decades of tribal fights have sort of culminated in a vague "all Software Engineering is Software Engineering" where most people understand that there are benefits even in the paradigms/languages they do not like.

In another world Excel would be just another one of those paradigms/languages but in this world it did not partecipate in the "Sotware Civil Wars" and so it was left out of the respectability plateau.

In short it is not that excel is bad but rather that the cultural link between it and what we usually call programming is very weak

You nailed it. At a previous firm (when I was in charge of ERP as well) we took over these kind of firms and moved them into our ERP either immediately or after a few weeks.

Manufacturing is orders of magnitude more complex. BOMS, Routings, all the raw and intermediate level skus, interfacing with the shop floor equipment. The much more complex accounts, many more people to train in more specialisms. MRP is so much more complex, planning is more complex.

> What I'm saying though is that the economics of fusion don't work. The temperature range, magnetic fields etc won't ever be 'cheap'.

> The Venetian lagoon is now off limits for cruise ships. But that's because it has sustained a lot of damage over the years.

The problem with Venice is more that the cruise ships bring in large amounts of "day tourists" - they come in in the morning, eat some overpriced pizza and pasta, buy overpriced Chinese-made "authentic" souvenirs, and leave in the evening, not contributing much to the local economy.
What is the lifespan of a car according to that graph? I am asking because it doesn't say.

My comment is that the lifespan of a car in the US is short (5 years, 10?) so ICE vs EV more or less evens out?

Considering old cars are exported to poor countries, that is another reason in favor of ICE since EV are a no go here.

You could call them "arenas" to be consistent with the prior art. Yes, if you can partition the heaps into ones with distinct lifetimes, good plan.
Sure, it is possible theoretically.

However, most relevant regulation (IEC61508, ISO26262, DO-178X) requires that systems controlling machines in automotive, rail or aerospace have a possibility of dangerous faults lower than 10^-9 (over the expected lifespan).

Many critical control systems like this are formally verified and/or extremely well-tested and have redundancy in both software and hardware.
Hi,

Great idea, thanks for this.

I didn't have the time to test it thoroughly yet.

One observation though: the hash IDs should be shorter, in my humble opinion, as to be able to read it once on one screen and type it in on another. Or, communicate over the phone. If IDs are so complex that I need to copy-paste them around, then, that kind of defeats the purpose.

Thanks.
I posted something similar for Colorado in that thread. HN has a lot of tropes that stem from fundamentally not understanding how elections actually work.
Nice to hear! How do you see yourself using this tool?
This is wrong.

You don’t need a Ph D or inspect code to know that your vote is included in a Merkle tree.

And you can verify that the vote total matches what is in the Merkle tree for your district, and the national Merkle tree of districts.

You can also verify that each voter was issued a unique token, which went through a mixer.

About the only thing you can’t verify is that the agency giving out the token hasn’t been corrupted and gave a lot of voting tokens to fake people, or multiple voting tokens. That part (preventing sybil attacks) is why Voter ID laws exist throughout the world.

But reducing the attack surface to widespread corruption issues involving voter registration, is much better than having those AND problets merely counting the ballots by hand, as when eg Al Gore lost to George W Bush in 2000.

The other thing you can’t verify is that other people’s vote wasn’t tampered with — unless THEY report it. Which is why the voting system should require voters confirming votes from multiple devices that verify your cryptographically signed choices, eg vote on a laptop then scan QR code from that laptop with your phone and approve, just as you would with a web payment request in your bank app, crypto wallet or WhatsApp sign-in request. Because voting is not as valuable to people as securing their bank account, this requirement must be enforced on all voters. This way one company eg Google or Apple can’t spoof the interface.

> The crude oil is bad, yes, but also used by cargo ships which must dwarf cruise ships by a ludicrous amount.

Cargo ships don't need much power output in port. The main power plants are shut down, usually it's only the (tiny) auxiliary generator unit in use.

A cruise ship however? That one runs orders of magnitude more electrical stuff all the time, and that's a loooot of fuel consumed.
Sounds like the early* days of software engineering, where everything was a big bowl of spaghetti you would never untangle again, compared to modular applications that you have nowadays.

Indeed, as others have mentioned, you get 60k queries for free! Don't even need to add a card. Then, you rather pay for the usage (primarily by number of queries) you have.
The $49 Pro plan you mentioned gives you additional features, such as more projects, higher query limits, and a lower $$ price per million queries.
On the Starter plan though, you can get going for absolutely free, incl. those 60k queries, and only pay for the queries above that.

We are also working on making this simpler to understand. We want to make sure our pricing is as easy to grok and as affordable as possible. Keep an eye out for improvements as we get to GA!

Its worth noting that Workstation and ESXi formats are essentially different anyway, traditionally you needed to use VMware converter to convert between the formats. Pretty sure KVM has supported the VMware disk formats forever so you probably can already migrate the VM's without too much work (just installing a few drivers inside the guest OS etc).
I don't know if you're joking or not but that is exactly true. Meta went as far as creating their own PHP engine and then a new PHO compatible language because they didn't have the resources to switch from PHP.

Instagram is presumably in the same position. Switching language is basically impossible once you have a certain amount of code. I'm sure they were aware of the performance issues with Python but they probably said "we'll worry about it later" when they were a small startup and now it's too late.
> My comment is that the lifespan of a car in the US is short (5 years, 10?) so ICE vs EV more or less evens out?

The average car in the US is 12.6 years old, implying that the average car has a total lifespan of something like 25 years (because the average car will be average, i.e. currently at around half of its total lifespan).

> Considering old cars are exported to poor countries, that is another reason in favor of ICE since EV are a no go here.

I don't think anybody chooses a new car based on what kind of charging infrastructure might be available to third hand purchasers in other countries in 20 years.

“Literally zero make the voter’s vote public”

In most US states I can get a voter’s database and “party affiliation”. I was shocked that thus info is publicly available, and all the people’s addresses and driver’s license info are also stored there (and can be leaked)

And make no mistake, these databases are regularly leaked / hacked: https://qbix.com/blog/2023/06/12/no-way-to-prevent-this-says...

In fact there is a law for states to create and maintain this information.
https://ballotpedia.org/Availability_of_state_voter_files

The “party affiliation” is a very good (around 95%) proxy to how they’re going to vote when they show up, as long as the two-party system dominates, which is why I say the whole “ability to prove your vote” thing is overblown, since your party affiliation at registration is already known, even publicly:

My main problems with checking spreadsheet code are:

1) Code formatting - spreadsheet formulae are generally presented all on one line with minimal spacing and no syntax highlighting. Any mildly complex formula should ideally be presented a) across multiple lines, b) with indenting to show function nesting depth, and c) in colour.

2) Copy and paste - spreadsheet formulae are generally copy-and-pasted every time they're used (i.e. on every row), rather than being defined once and referenced in each place they're used. Some spreadsheets are now good at highlighting if one formula is out of place in a column of otherwise-similar formulae, but it's hard to check if formulae are supposed to be "the same" in different columns, or different worksheets, or in different spreadsheet files.
