Yep, gnome 44 is definitely not good enough yet. I’d advise not to upgrade to 23.04 right now and wait at least a month for fixes to come. While I haven’t noticed major regressions personally, gnome and its components are producing little but annoying bugs. 22.10 was awesome from day one, 23.04 is not.

The short version: have your harmony or bassline go down when your lead melody goes up, or vice versa.

(It’s not that easy in theory but that is the gist of it.)
The US equivalent is a minivan; which everyone seems to agree is absolutely impossible to admit buying unless you’re a housewife with small kids. But they’re incredibly practical.
A couple reasons might be the chicken tax (25% tariff on all imported trucks) and if it's "too small" it might be in the category of light trucks where the EPA imposes very strict fuel economy standards.

I blame regulatory capture for both of these things. Gotta protect American big truck manufacturers from competition from smaller, lighter, possibly cheaper vehicles.
It’s not accidentally though, it’s entirely on purpose. I work in climate tech, or sort of, because what I really work for is an investment bank owned by a hedgefund, and the sole product we sell to investors is good returns.

You can do that in a lot of ways, however, but our way is to use their investments to build green energy plants, ride them to a profit and then sell them. Which creates a better world, but it’s very much intentionally. The increasing climate awareness, especially among the generation of wealthy 60+ year olds who want to leave their grandchildren a better world is simply a good business case. It’s much easier to sell that group of people a green investment in 2023 than it was in 1993, in fact it’s hard to sell them an investment that is not green. That last part is why you see the corporate world turning eco-friendly. But I think it’s wrong to say that’s it’s accidental, because it comes after five decades of climate science and politics turning the hearts and minds of society, and now that they’ve been successful, and there is a lot of money to be made off green energy, the corporate interest follows.

I’m not a fan of the way lobbying impacts our democracies, but it’s primary function isn’t to be evil (at least not in general terms), no, it’s primary function is to influence society in a way that allows businesses to make money. If society wants cheap gas in their cars, or if big sugar/tobacco wants to keep their massive market shares then lobbying does evil, but if the best way to make money is to generate a profitable green energy market, then lobbying will likely do good. At least as far as capitalism is concerned. You can think about that what you will, I would personally prefer if my own government had not sold off much of our energy sector as a citizen, but I both work and invest in the sector so it also benefits me immensely as an individual.

That being said. By 2030 we’ll have build more than ten thousand solar plants of different sizes, and while we couldn’t have done that without climate science and climate NGOs (and corporate lobbyists) creating a political climate to drive green energy forward, climate science and climate NGOs couldn’t have build those plants without private money. So while it’s fine to have ideals, it’s the realism and the compromises that actually change the world.

Yes, and they are thousand time more usable that the "modern" crap.

GUI design is going backwards since 10 years.
Yes. 12kWh/kg chemical energy for kerosene, a little more for avgas. But with a 25% efficiency you are only getting 3kWh out of a kg of fuel. Electric motors tend to have higher efficiency -- maybe up to 75% so you might nearly get 500Wh from a kg of battery.
Current mass produced batteries, which tend to hover around 260-300 Wh/kg. Higher density (but still under 500) are available, but in far smaller quantities for a very high cost.

The exciting part of this announcement is that if anyone can scale manufacturing, it is them.
Electric engines may be much more reliable than kerosene engines.

The training sets are different in nature, not in the sense that 2 different LLMs' training sets are different. And that does not even touch that humans do not just learn from "training sets" but from interacting with the world. More like RL but not like ChatGPT's fine tuning; humans take _actions_ and they _experience_ their results in their totality, not just a "good/bad answer" feedback.

I am not saying that we cannot produce an AI with capabilities of that sort. But LLMs offer nothing at all to that direction. They can be useful in certain practical stuff, they are overhyped as hell, but they are not a step towards AGI.

I like the headline, specifically aimed at aviation. This might definitely turn some heads. While this is still strong on the marketing with few details, it shows the intent to electrify air travel at some point, which is a good thing IMO. Also might put pressure on SAF, which themselves have a long way to go.

Also, this could be interesting already for existing small and/or short range airplanes like Pipistrel‘s training aircraft or Eviation‘s Alice. I don‘t know the energy density of their current batteries, but this could give them a boost very soon.
I've used IRC for years and people being confidently wrong has always been an issue.

LLMs are definitely a new concept, but not every facet of them has 0 precedent. Someone surfacing a bad source repeatedly isn't new, you label the channel so people know it's banned, and if the same person keeps surfacing bad info you mute them, then ban them if it continues.

If you have a sudden influx of low quality new users it's also not new, you require authentication and that alone cuts down on a ton of spam
Social space vs enterprise space. How many companies would want llms integrated with their corporate data, but need trust about the data not being leaked?

Microsoft and Google both have the capability and trust to make this available. When corporates start paying for LLMs, per user, or for applications, both Google and Microsoft and the two companies are in the best position.

All other industries will be users paying for LLMS model access.
Surprisingly enjoyable. Make sure to stay for the phone conversation about mining.

I usually don't take messages about mobile performance seriously, but this does bring even A15 Bionic devices to their knees. I wonder whether it's a RAM or GPU issue, it plays nicely for a few seconds and then dies.
They will sell the hardware to unwitting victims as new via eBay, Craigslist, … and disappear before the victim figures it out. It is a new iPhone in the original shrinkwrap - who’d become suspicious?

It's more like mopeds to motorcycles. If your moped went slower than 25mph and had an engine smaller than 50cc, they were treated more like a bicycle than a motorcycle.
As someone in the industry, I'm aware that Shim V2 is no longer the best option for pod management due to its poor reliability and high memory and CPU consumption. The long call-chain often results in data inconsistency, jammed IO or dead shim. Despite these challenges, it's difficult to push for a new approach. That's why I'm excited to see this extraordinary project that addresses the pain points of Shim V2 with its Sandbox API extension. The architecture description promised better performance, and the benchmarks in the repo exceeded my expectations. Well done, folks!

I'm also glad that the framework is open, allowing for engagement with various sandbox technologies. Additionally, the removal of the pause container is a significant improvement. Cheers!
Apples lockdown even includes hardware such as screens. You can’t just transplant an iPhone screen from one phone to another.
For the frontend: put a CDN in front of it, add caching.

In my experience, most folks just want to see what the fuss is about, not so much make an account and start using the app. So as long as your post-login experience can take a few users simultaneously, you should be fine.
I think many users here would have a heart attack and die to realize how many semis on the road are entirely empty (deadheading) and how many are filled way below capacity.

Most truck owners I know use their truck as a truck quite often. But that’s more rural; maybe everyone in a city commutes in an F150 for absolutely no reason at all.
...or to anyone who ever rode a bicycle or motorbike with front and back brakes. Pull (bicycle) or press (motorbike) the back brake hard and the rear wheel tends to skid. Pull the front brake hard and the thing wants to somersault. The back brake is needed to stabilise the vehicle but the front brake does the real work.

I'm not sure we have proof it's that effective. Recently 400+ phones were stolen from a store in a well prepared way, so I assume there's plenty of ways to work around or get value from the stolen phones despite whatever Apple is doing:

The airplane would be a bit heavier at landing, though. I expect that will require a somewhat heavier landing gear.

I also think taking out the weight of the tank is unfair if you don’t add weight for the structures for holding the batteries.

But yes, for many smaller planes, we’re close to flying electric on shorter flights being economically feasible.
... aren't jeans and backpacks the most typical pants/container? What the heck else would you wear and carry things in while scooting around?

You might be seeing the problem as much simpler than it is. Have a think:

* Only US gov websites, and not every country's equivalent?

* And only on their country's specific TLD, because some countries do have official government sites using .com or non government TLDs!

* And which banks? Only banks? Why not other financial institutions?

* Where would such a list be stored and maintained? Who would be the arbiter?

* How do renames and rebrands and defuncts get handled?

* How do you prevent malicious third parties getting onto the "no extensions" register?

Just listing these questions out, I can see the problem spiralling very quickly.

It could be stated simpler as, why can't my browser allow me to disable extensions for specific domains of my choosing? To which the answer will probably be, because that's another potential attack vector. A victim could be told to permanently disable extensions for a specific malicious domain.

So if I wanted this feature I might choose to approach individual extension developers and ask them if they'd be willing to disable the extension based on a specific list of domains. Again I think security concerns would make them say no but that's the narrowest 'scope' that you could ask for.

I feel that synthetic kerosene via electrolysis is a far more viable path to sustainable aviation than battery-electric engines. The energy-inefficiency doesn’t really matter as long as you can keep the total cost of the flight within consumer reach.

Why would activation lock prevent stealing a new phone? Definitionally a phone that has not been sold doesn't have an account tied to it.
This is more about day to day operations than emergencies. For an electric plane, your MTOW (max takeoff weight) is equal to your MLW (max landing weight). An ICE plane can take off with "bonus" fuel that it can't land with for structural reasons, while an electric plane can't.

Bicycles would benefit as well. I would love if my electric bicycle were slightly lighter.
It's a shame that -fno-math-errno isn't the default. It pessimizes many common operations, as can be seen in the article. Also e.g. a simple sqrt() call like

#include <math.h>

double mysqrt(double d) {
return sqrt(d);
}

with and without -fno-math-errno: https://godbolt.org/z/bvrz9r8ce

One can see that with -fno-math-errno the function can be entirely inlined. But if errno is enabled, it has to first check whether the input is negative, and in that case call the libc sqrt() function which sets errno.

As for why it's not the default, I guess it's historical. The errno approach was common back in the days before IEEE 754 with its exception model provided another way.

E.g. for glibc: https://man7.org/linux/man-pages/man7/math_error.7.html

Musl libc, being newer, does away with that and never sets errno in libm functions: https://wiki.musl-libc.org/mathematical-library.html
Really intresetd in the management model that Kuasar has proposed.

It's fascinating to see how the shim process has evolved over time with the container form, from one container corresponding to one shim, to one Pod corresponding to one shim, and now to Kuasar's innovative proposal of one type of Pod corresponding to one sandboxer process, meaning N pods corresponding to one process. The evolution of the model has reduced the number of processes to only one, which has consequently reduced the memory consumption and helped with startup time.

Overall, I find this project to be quite exciting, and I'm hoping that the model put forward by Kuasar can be widely adopted and applied in production.

500-600 Wh/kg is the target for replacing average flight durations.

Fuel is one of the highest costs for an airline, so eliminating the majority of that will make the demand for any viable options go bananas, even with a much higher upfront cost.

Being seen as 'green' is a big bonus for the airline.
And the users have been getting steadily worse too...
A colleague and I were once discussing the fast inverse square root and joked that we need to make a (neural net) activation function that uses an inverse square root as an excuse to use the fast inverse square root. At any rate, I did come up with an activation function that is very similar to Swish/GELU but uses an inverse square root:

https://twitter.com/danieldekok/status/1484898130441166853?s...

It's quite a bit cheaper, because it doesn't need expensive elementary functions like exp or erf.

“Next-gen” is too generous. Such a poor-man’s Lisp machine would be a step back in many ways.
Exactly. Adobe also sounds weird to me, whereas Gimp doesn't mean anything at all.
Is that something that is happening? I would have thought it would have been in the news before if apple had been doing that.
That is a very good and often overlooked point. So in average on a flight one has to calculate maybe with 60% weight of kerosene, while the battery keeps 100% of its weight during the entire flight.

I wouldn't say SBI there belongs with the others.

For starters, it is a fairly simple, open specification of an interface[0], with an open implementation, opensbi, that so far everybody uses.

Furthermore, it is not "hidden" in any way from the OS, which can take over its roles, partially or completely.

Were these philosophers generating science?
Not every flight is transatlantic.

These batteries, if they deliver on the advertised specs and aren’t too expensive should make short-range electric aviation possible.

The electric air taxis that Joby and others are working on suddenly have a lot bigger margin to work with, as do electric regional airliners.
As a small nit on the benchmark code, should use CLOCK_MONOTONIC rather than CLOCK_REALTIME.
Would you say I am pessimistic if I believe that a tiny fraction of those actually care about the environment while the rest is in for the easy money?
Layer 2 (Ethernet) DCI will often be set up with 9000 (or larger) MTUs - the reason for this is to allow end-customers to carry their traffic using whatever encapsulation they want to internally (eg: Q-in-Q, MPLS, VXLAN, MACSEC, GRE or all of the above simultaneously), and the carrier/DC will transparently support it.

But when it comes to external L3 peering between 3rd-parties (eg: the Internet), it's very rare that people will mess with the IP MTU. Unless you can guarantee that the IP PMTU is higher than 1500 bytes (across multiple segments that you may not control, including ISP last-mile) there is simply no benefit.
Starting life in (or getting eventually out of prison back to) a highly individualistic society, where "you're on your own", and one where gun ownership is trivial, doesn't help either.
Surprised that they haven't despite garnering interest and funding. Likely that it is not an easy problem to solve!
Not at this density. This is the minimum requirement for medium length large airplanes. Small aircraft are already viable with mass produced batteries.

As they scale production of these, hopefully they can get 20% additional improvements at the cell/pack level, reaching potential to replace the most common flights.
Apple can still lock those phones. They track what is in stock and what has been sold
Fair points.

But the point that CATL makes with this announce is that before this capacity boost, electric planes were a complete joke. Now, they are only somewhat funny.

What I am more excited about is that electrically pumped rockets are now a lot more practical. As an example, Electron is such a rocket ([1]). It can now reduce the weight of the battery pack and increase payload.

Loved this, it's something I think about a lot. I "grew up on the internet" and spent a lot of time in my youth making flash games/videos for me and my friends and we always had such a great time. Even today, 20-some years later, a lot of our vernacular from flash videos still finds its way into our speech- "fire ze missles", "badger badger badger SNAKE", that kind of thing.

The bit at the end about "the old ways" still being needed sometimes... it reminds me of a story I saw recently about how we're still researching ancient Roman concrete and finding secrets about why it's so durable (https://news.mit.edu/2023/roman-concrete-durability-lime-cas...) Makes you wonder how many artistries have been lost over the years, and what kind of stuff we work on today that will be lost in the future. I spend a good 50 hours a week toiling over code, and already I see that changing a lot over the next 10 years. I can't imagine what it will be like in 50.
>This is already continuously tried. All it creates is a lack of trust in the justice system. If you remove the ability of the justice system to make the people feel that justice has been served, people will revert to vigilante justice. You need confidence in the system.

Sorry, but that's just ignorant. Countries with non-retribution based justice systems fare much better in lower crime than the US. So much better it's not even funny.

>I'm not saying the American justice system doesn't have issues. I'm not American personally, but it appears to have a lot of problems. However, I don't think incurring consequences for people's actions is the root problem here.

"Incurring conseqeuences" is orthogonal to the issue here. Going to jail and being kept there is already a consequence.

The US system turns "inflicting medieval/biblical conditions and systemic revenge" into the consequence.

Peek – Effortless OpenAI API Monitor from macOS Menubar
Hey HN!

First time posting, I've built a macOS menubar tool to better monitor OpenAI API usage / cost.

The idea came after racking up a $5 bill in a matter of minutes while running my Oura ring data through GPT-4 (with 6k+ tokens). So I set out to have a glance-able way of tracking and knowing my account spending, for personal usage for tools (dev / playground / apps you add your key to) but also production apps, for monitoring spikes / API abuse or attacks.

The app is built natively with SwiftUI, took a couple of hours to put together and released same day on Gumroad.

I've linked to Gumroad, it is pay what you want, set $0 to get it for free – rather people use it than pay for it, but ideally both!

I've since put it in the macOS app store for the more security conscious (aka approved by Apple) at a price of £5 with the hopes that using the tool should save you that in the long run:
https://apps.apple.com/gb/app/peek-ai-api-monitoring/id64476...

Appreciate your feedback!

Thanks,
