According to the data source, about 20% of the “EV sales” are PHEVs:

> A total of 100,605 plug-in vehicles (81,346 BEVs and 19,259 PHEVs) were sold during March 2023 in the United States

That’s actually higher than I expected. The availability of PHEVs in the US has always seemed pretty terrible to me.
Sounds like Midori/Singularity. Or like any of Per Brinch Hansen's OSes, written in concurrent dialects of Pascal and depending on the language-level constructs for memory protection and process separation (they could and did run on machines without MMUs).
The pattern I see most often falls into #9 and #10. Not only is the 'Accept All' button made more prominent, but other design tricks make it the default selected item. Tapping space or enter on a keyboard would click it, making it possible for the user to unintentionally opt-in through a slip of a finger.
So what, gathering capital from dumb kids so they can do things that matter to them is bad?
The difference is

a) trust - many don't outsource because the are not willing to reveal company code, are worried the outsourcer will sell their logins, etc.

b) availability - AI will drive your kid to school, do his schoolwork, choose him content to watch on his phone, and find you recipes. At some point it will likely also prepare the dish.

c) cost (as you pointed out) - Even if you could send your kid to school by taxi, etc it would be prohibitively expensive.

d) reliability - the level of AI is pretty low now, but as that improves you will get a less mixed bag than outsourcing.

MTU is ridiculously difficult in telco networks. Because most transport is moving packets via Ethernet at the endpoints, you’ve got to make sure your customers can use whatever MTU they want, including 9000+. This means a lot of variation in frame size support, even within individual vendor product lines. Now, let’s see here…is a jumbo frame 9000, 9192, 9216, 9500, 10000, 16000 bytes in size? Who knows. That’s just Juniper. Extrapolate this uncertainty to dozens of different vendors and models of networking gear, AND how they each count bytes, interframe gaps, 802.1q and 802.1ad…

That'd help, but it is really not the same as fine electrodes talking to just one or a pair or triplet of neurons.

Once we're out there, we're either using an array and a lot of signal processing (sort of reverse synthetic aperture radar processing) to identify detailed signals, or just using aggregate signals.

In which case, why not use more gathering points and processing power and just go outside the scalp, avoiding infection problems entirely?
This does come up a lot ... for ethanol production. How much fuel is used to produce ethanol is constantly discussed, with some people claiming it is barely break-even or even energy-negative.

But yeah, no one then goes on to give equivalent numbers for petroleum.

The question is how do you fix that situation?
> you don't think that people can make statements on whether something is ethics or not

Ethics are subjective, not objective. I think people can make statements on whether something fits within their definition of ethics.

If you can think of an objective way to define ethics, one that all reasonable people operating in good faith would agree with once they heard it, then you'll have done something no philosopher has ever achieved.

Ethics are a function of values. First you place values on different things, like happiness or virtue or the preservation of life or obedience to god (if you think there is one). Then you work out the implications of how those values influence the decisions you make, and then you have ethics.

As long as you're doing this process, it's ethics. It's somewhat analogous to math in that once you define some axioms, then you can do math. Different people might choose different axioms, after which they won't agree on everything, but they're both still doing math.
And in fact this number changed by large amounts in the last decade, even before the current boom of the 2020s.

Remember peak oil, which was a big panic of some in the 2000s? It turns out that peak production didn't happen overall, but if you look at the original set of "known resources", the peak oil predictions were spot on. Yet we didn't experience huge oil supply shortages because huge expenditures into new fracking tech enables far more resources to be accessed.

We have always loved in a complete abundance of lithium, so we never bothered to look for more resources. Now that we need more, we will find it. It's not a particularly rare element.
Tom Kyte, who for a long time was the "ambassador to the world" for Oracle, makes essentially the same arguments

https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUEST...

For data that will either :

+ 'outlive' the user interface - this data will be used forever but we are not sure where e.g. financial docs, records, etc etc

+ 'extend' past the user interface: this data started on an installed desktop app / green screen but we are not sure how we may want to extend it - eg to an API or to web

the DB is the right place to put business logic.

Coupling the data with business logic, in the DB, allows almost complete flexibility in how it is access and interacted with at the expense of complete lock in to the DB platform. Which may or may not be a bad thing. But if you have a skilled SQL team and some resources to pay the DB licensing and support piper, this is a good direction to ensure app support longevity.

For example, you can do the same thing on desktop or phone or web client or even hardware switches: say you have a DB stored_procedure to indicate that the process of manufacturing this part has reached stage X

update_item_status( Item 11111, 'Manufacturing Stage X' )

(these is obviously really contrived but it is an example to make things clear)

You can run this, if it is in the DB by:

- hitting this button on the assembly line

- scanning a barcode can do the same thing

- having a user change a status in a UI

- have a batch job run off a script with a list of parts to apply the status to

And even better, if you want to update how the stored proc works, you update once in the DB and it is available to all 'interfaces' instead of having to update hardware switch code + user screen UI code + batch script code etc etc...

I know that an argument can be made that you have an app server layer separate from the DB so this is not a 'real' problem but this approach just puts the app server IN the DB

One closing thought: it is often easy to forget that, in most cases, the data is the product of software development and the tooling is just support. Only counterpoints I can think of here are games and interactive demo systems where the process ( of playing the game or using the software ) is the product.

Positioning the database and front-end as being similar is a mistake if business goals are thought about from a "the data is the product" perspective. If the rules about how to handle, manage and interpret the data are a core component of that data product, then the argument that the right place for business logic is in the DB is made even stronger.

For what little it's worth, I never trust this statistic because the unemployment rate calculation doesn't count certain types of people: such as those who've given up looking for work. Given the weird times and general malaise of society, this might be a non-trivial variable right now. I could be wrong about this, but it remains a possibility that we're not getting the right picture of what's happening.

Show HN: Appteum, a low-code backend development platform build for developers
Hi HN community,

We are Nikolas and Giannis, founders of Appteum. For the last few months we've been building Appteum and can now share our public Beta with you. Appteum is a low-code Backend development platform that makes it easy for developers to configure the backend for their apps. You can configure your backend in our web app and then using our Typescript SDK you can interact with your backend in your code.

Why we built this:

- We couldn’t find a low code tool that provides the backend abstractions we needed but at the same time retain the flexibility of dropping down into code.

- We found current low-code tools like Bubble and Retool don’t offer a great experience for developers. We prefer using our own IDEs, version control etc.

- Sometimes, you need to use a service that is not supported by the low-code platform. It would be great if you could write a few lines of code that would make it easy to integrate into your app.

- From our experience, the traditional way of building APIs is time consuming and repetitive. It would be great if the API would reflect any change on data or security definitions automatically.

Our beta version lets you:

- Create Objects, Fields and Relationships (Objects are equivalent to tables in relational databases).

- Define object-level and field-level security for your users.

- Query your data over our API using a simple SQL syntax.

- Get access to your objects data instantly with our APIs.

- Import our Typescript SDK in your app and conveniently access your backend configuration.

Our business model is to give developers and their companies a development platform that abstracts away the backend development of an app.

While it is a beta, we believe that even today the experience is meaningful. We are working everyday to make Appteum better for our users. Please give it a shot at appteum.com and let us know how it goes. You will notice that a log-in is required, we don’t collect any telemetry data of our users!

Sometimes it's easier to rewrite a module, given inputs and outputs and a good test suite, than to understand how it works. This is even more true if the original developer is no more available.

Rewriting a whole big library, not easy either way.

Hi everyone,
We have been dealing for a while with the underperformance of Time-Series Machine Learning models (mostly due to regime changes), and haven't found the right library to complete Adaptive Backtesting before the heat-death of the universe.

We ended up writing a library from scratch, that comes with an order of magnitude speed-up, called Fold.

--- This is the launch of our core engine so we would love to get some feedback on Fold (https://github.com/dream-faster/fold)! We’ll be here and happy to answer any questions.

XRP is a regular BPF hook in Linux and requires no additional standardization. The device never "calls out to BPF programs in the driver" - it generates a normal completion interrupt and Linux runs a BPF hook in the completion path. This is no different than other kernel BPF hooks elsewhere and doesn't provide any additional reason or need to standardize BPF.

The article misstated that XRP was a framework used for offloading BPF programs to NVMe devices. That's not correct, and XRP is not one of the emerging use cases for BPF that is driving standardization.

Isn't that the point? The problem is that the customs of others is infringing on the customs of others. If some places insist on a policy for their people, that is fine for their people. But what we have here is an insistence that those people can control how other people outside of their place and people can see and access technology.

If you abide within that pattern, policy debates will also appear one-sided to you—the costs and drawbacks of your favored policy are enemy soldiers, to be attacked by any means necessary.”

I've been using Privacy.com cards for years to avoid this. Set a limit of 1 month on the card, and if I'm actually using the sub I'll fix/update it when the sub runs out.
I should clarify: training is not latency sensitive, so you can run your workloads at off-peak hours when people are asleep. Inference means you need to run your workloads at peak when people are using your service.

(Looking back, I'm happy that I was careful in my wording in that I didn't say diurnal cycles aren't relevant, just that they aren't as useful in this case)

That said, I suppose I misread the specific suggestion about spinning down servers off-peak and was thinking more about spot pricing at peak vs trough.

Hydrogen fuel cells in mass produced vehicles do not have a future since hydrogen does not actually like to react - you need a catalyst. And the best ones we have are based on platinum, which is very rare a expensive. If we produced any decent quantities of "hydrogen" cars, we would have such a shortage of platinum we would not be able to complete them. Of course there are claim this has been solved but to the best of my knowledge no such catalyst actually ships in commercial quantities. [0]

The second reason is that hydrogen is 1/10th the density of diesel even when liquid (which is as dense as it gets). Maintaining hydrogen in its liquid form is energy intensive. Hydrogen tends to leak through the smallest cracks and also because the atoms are so small tends to leak even through solid metal. To sustain the high pressures and degradation by hydrogen you need a very expensive tanks. You also need to handle the case, when the car crashes/ catches fire releasing all of the hydrogen somewhat safely. This tends to be a 6 MW flame upward of the car. Too bad if it crashed under a bridge or garage. This is much worse than a burning ICE/ BEV car.

Hydrogen gas stations have all of the problems with the tanks as well. That makes them very expensive. Battery charging stations are somewhat easier - everywhere you have higher voltage you can build a decent charging station. Big parking lots can have solar roofs fulfilling a part of the charging demand and keeping the cars colder in the summer.

At the same time you don't have any of the advantages of batteries - such as that you can charge them almost everywhere or when breaking. Hydrogen cars would need to be hybrids basically to improve on these, in this regard they are more similar to classical ICE cars.

Finally, making hydrogen ecologically and economically is not that easy in big quantities. In the end, you realize it is means to a longer operation of the infrastructure of classical fossil fuel companies. Unrelated to cars, you can put some hydrogen (up to about 8% it seems) into natural gas without noticeable change in properties when used for heating. But you can probably slap a green or at least "blue" stamp on the solution. In the end, all of this is just as damaging as the production/ burning of bio diesel/ gasoline spiked with ethanol. Putting hydrogen into cars would just make support this fossil fuel agenda without actually helping the environment much and quite possibly enable decades of even more damage to the environment and public health with profits mostly for just a few already filthy rich people.

But Nemo does exist, it's just not actually very intersting since it's notable only in this abstract sense. Similarly when the Americans build a base at the geographic South Pole (Amundsen-Scott base) the Russians built one at the pole of inaccessibility - the place furthest from the sea, which is not interesting in the same way as the actual South Pole, but still a desolate horrible place to be, grossly unsuited to human habitation. Unlike Amundsen-Scott, I believe that Russian base is no longer permanently inhabited 'cos it turns out that's very expensive and the Russians don't have the same budget for such things.
Thanks for the question!

So the way that Bend works, we take a transaction, and then match it with the best available 'emissions factor'. So, for example, if you purchase something at Starbucks, we match that transaction to the Starbucks specific emissions factor: https://bend.green/starbucks

Over 65% of total market cap is now covered by this sustainability data, and we aggregate that data, and use it to estimate the emissions for each transaction.

Of course there is a very long tail. So if you buy a coffee at a small coffee shop, we likely don't have that merchant-specific data. In those cases, we fall back to "Merchant Category Code" (MCC) emissions factors.

And finally, in some cases we have SKU-level data. E.g. we have an Amazon Business integration where we get the actual specific item data.

Long story short is we have surprisingly high merchant coverage — well north of 60%. We have pretty limited SKU-level coverage today, but expanding. And then we always have an MCC fallback. The larger the merchant, the more likely we are to have good data for them (we're trying to grow coverage for mid market and smaller businesses with Bend).

This means that you can get a pretty detailed, totally automated sense of your emissions hotspots.
