The fleet average real-world fuel efficiency for light petrol vehicles in my country, based on government data, is 9.2 litres/100km. (I'm guessing it's significantly worse than this in the USA where the average vehicle is larger and there is less focus on fuel efficiency)

At 8.9 kWh per litre, that means gasoline takes 81.88 kWh to get you 100 km. A typical EV, on the other hand, will use about 18 kWh to go 100 km (at 5.5 km per kWh). That makes the EV around 4.5 times more efficient.

As for carbon emissions, burning 1 litre of gasoline creates 2.3kg of CO2. At 9.2 litres per 100 km, that works out around 210g per km.

Grid carbon intensity varies greatly by country and region. In France at only 42g/kWh, an EV's energy would emit less than 10g per km, even after accounting for grid and charging inefficiencies! But even in coal-dependent Germany at 354g CO2/kWh (2023), an EV would be well under 100g per km, still better than an average petrol car.

(Also, remember that auto industry emissions/efficiency numbers are based on testing protocols which produce far lower figures than the real world. And do not account for upstream emissions in the fossil fuel supply chain - there is an awful lot of upstream carbon emitted to produce 1 litre of gasoline!)
I know we had the "percentage points" vs "ratio of percentages" flame war here recently, but saying "only a few percent" without pointing out that the emissions are 450% of what was expected is frustrating to read; I kept expecting someone to point that out in the article...

Montblanc, Lamy and Pelikan make good money each year with Fountain Pens. If you have to write an Examen in university you would also prefer a fountain pen, because Stuff written with Biros looks like Shit as opposed to Gel Pens or Fountain Pens. And yes the looks also matter there
I would imagine it activates some motor neuron ganglia that is somehow connected to a flap reflexive action, and then sometime afterwards fine motor control is gained by practice; akin to plantarflexor muscles in a walking stride.
All I've ever wanted was an opt-out, but this works for my purposes as well.
Native Australian English speaker here: I would 100% interpret that as they camped on the beach because that’s an option at some places here. Goes to show how it’s cultural I guess.
I'm a bit sad to see the anti-curious commentary here. This result is really cool, and finds the asymptotic sweet spot for hash table memory usage. Often times, the first algorithm to establish an asymptotic limit is entirely too complicated and doesn't help at human scale. If the world collectively ignores such results, as many here seem inclined to do, that's the end of the story. But when somebody continues bashing their head into this wall, sometimes a really good algorithm falls out, which hits that asymptotic performance benefit at a human-useful scale.

The thing I'm curious about (as I haven't had time to cozy up with the paper, and I'm about to run) is how they hit that runtime. What's the big idea? Or is it just the gestalt of a dozen slightly clever ideas?
So, just a random HN reader here, but:

1) the big competitor might validate the need for the thing in customers' minds, without providing a good implementation, which could conceivably actually accelerate your success.

2) if they're that big, then if only 10% of their customers want or need the 20% of your product which the big company doesn't provide, that could still be a big amount of money for your product.

3) if their product does poorly, their CEO might decide to buy a small competitor in order to fix things; you could be that competitor, if you are the best one available, so it might be worth sticking around for that check.

Of course, it might be that none of this happens, your big competitor's new features squashes you, and that is that. You would want to ponder how to handle that scenario, both as a company and personally. But maybe it would not be good to assume so quickly that they will do things well; plenty of big companies with successful past track records flounder at rolling out a new feature.
No, doesn't work for me. I find these "works for me lmao" posts really worthless. Just scroll past or whatever like everyone else does
Vaclav Smil's books about energy give some extra context. I have read his Power Density book (eye opening comparison of solar, wind, nuclear, fossil).

IIRC Gas extraction has an extremely high EROI (30x) initially, making it a highly productive extractive resource. But each gas well has a productive lifespan of approx 7 years requiring constant activity to sustain development.
Lots of interesting comments on this one. Anyone have any good resources for learning how not to fuck up schema/db design for those of us who will probably never have a DBA on the team?
The capabilities work fine for much of the country that doesn't get exceedingly freezing temperatures. It only gets down to about 26F on the coldest of cold nights here once or twice per year.

Brilliant fan fiction that takes a few liberties, but it would be interesting to have The Thing's perspective if The Thing was made into a series. I think in the movies was just supposed to be cosmic horror who's only real goal was to survive by spreading. Communicating with it would be pointless, unlike in Watt's story, where you have a fundamental philosophical difference based on The Thing's understanding of biology, but you could at least have a meaningful conversation with it.

> what happens when your senior engineers retire and there are no replacements prepared because it's more efficient to hire foreign senior engineers rather than onboarding and training a college grad

This assumes that the overseas engineers aren’t senior or reliable? I (in the US) work with a lot of talented and dedicated overseas folks who keep me on my toes. Some of them are founding or staff level engineers of our SF-based startup.

True, the utility of a camera draws attention away from any nefarious possibilities. I also think our relationship with cameras is different from when google glasses came out. My seven year old niece will film herself dancing using her mums phone and even though its just recorded to the phone she'll intro the video 'hi everyone', probably from the content she's exposed to, tik tok etc. 'Audience by default'
I guess they know that nuclear is a failed proposition in the US (and everywhere except China) so they can redirect focus from renewables into chasing this bridge to nowhere.

This has been the case since the new code search replaced the old one ~9 months ago. The new code search is more resource intensive so Github chose to only make it available to users. I agree that it sucks to not have code search available when logged out, but it's not a new change and I don't think it was done with malicious intent.
I can't believe crypto is coming back and driving back up the prices of GPUs as we finally find a use for them [1].

It's annoying enough having cash-rich crypto companies pivot into AI
(with no idea what they're building and no product sense), but now we'll have to fight for consumer GPUs too.

And to anyone equivocating GenAI to crypto, realize that the former brings incredible tools and productivity boosts. Tangible value. Ordinary creative people without deep skills can use GenAI to draw masterpieces with LCMs. They'll be able to direct films and make music. There's still a curve, but it's gentle and the rewards are outsized.

This was exactly my question, have people looked at the various thermal management techniques used in computing? Heat pipes on the backplane and fan cooled heat sink blocks could go a long way.
It’s been six days now of solid work on it. Seems to be sticking.

The improved ergonomics include greater physical flexibility and comfort, as well as the visual benefits.

Physically, I am now moving as I feel inspired, between my desk, a couch, bed, and an egg shaped chair with a foot rest. I only need a keyboard/trackpad on my lap, and my MacBook nearby.

The visual benefits turning your whole mental visual space (your fovea, peripheral vision, and head turning field of view) into a visual desk of any number of items is fantastic.

Being able to make my main screen as large as a wall is nice. Seems like for some work, a smaller screen feels better, for other work a very large or wide screen helps.

Downsides:

1. Needing the Mac at all. Would love it if Apple shipped Xcode and Terminal for the Vision. For now I move around and would travel with both.

2. That first one would solve this. But for now only one Mac screen

3. The Vision screens respond to both keyboard/track pad and look/pinch, the Mac screen only responds to the former. You get used to doing both.

Great point, LLM will not be great at ground breaking law.... But most lawyers aren't. That's to say, most law isn't cutting edge. The law is mostly a day-to-day administrative matter
Wow, yeah.

But if you imagine it said in a fancy accent by someone holding a stack of bills totaling $4000USD does it change the meaning? “On the beach” has to be in very posh accent.

Great post. I do wonder - what are the simplest K8s alternatives?

Many say in the database world, "use Postgres", or "use sqlite." Similarly there are those databases that are robust that no one has heard of, but are very limited like FoundationDB. Or things that are specialized and generally respected like Clickhouse.

What are the equivalents of above for Kubernetes?
The entire device is “no computer required”, just like an iPad for your face
That's okay, GitHub's search is atrocious anyway.
They’re just closing it, wow.

Someone had recommended me Skiff, but I stayed away from it and opted for Proton, given that they have been around for a while and Skiff smelled like VC money too much. I guess it was the right choice.

At this point, a criteria I try to follow when I have to choose whether or not to rely on a tool is: is it funded by VC? If so, steer clear.
Sorry, what's the news on Proton?
I know exactly where each bit of info is, and I just dart my eyes to the appropriate monitor, or tilt my head slightly, which is far, far easier and faster than switching through dozens of windows to find the one I need. The windows I need are already open exactly where they should be, I always know where they are, and the latency between me and the data I need is practically nothing, zero.

My three 32" 4k screens are equivalent to 6 pretty big 24" screens, essentially one big 55" screen and sitting with my head against my chair's headrest I my eyes can see every corner of all of it without having to move my neck one millimeter, my eyes effortlessly move around and I can see all the data. Maybe you have some kind of problem with your eyes that prevents that, but it's absolutely easy to find the data I need with zero additional effort.

It's way more efficient than having 1 screen and locating the data required constantly. The difference in friction is very noticeable and painful when I'm only on one screen because it does slow me down, and there's no way around that for anyone, one screen always means more cognitive load and higher latency to getting the data in front of your eyes. Shortcuts and virtual desktops don't change that. And, often things happen that I catch in my peripheral vision, like console logs I'm expecting to happen, that I wouldn't be able to catch if the window isn't visible.

Sorry but you'll never convince me that 1 monitor is in any way superior to multiple monitors, it just does not compute.
I watched a for all mankind episode in it today in the cinema environment and that was really good.

I’ve similarly watched other videos and it’s good at that, the four immersive video examples are cool.

Window nav is meh, the eye tracking isn’t quite good enough. The windows aren’t small enough to be super useful when trying to do real work on the Mac, for productivity work it’s disappointing in this first version.

I can see how with future hardware you could actually wear all the time, leaving windows in certain locations around your house could be useful, especially if some were shared.

The potential is clear, but it’s still an early adopter device. For media (particularly video) consumption it’s great.

I think my prediction from 2021 held up well: https://news.ycombinator.com/item?id=27583456
This is objectively correct. You can't get trademark on descriptive things (or abbreviations thereof). If I made a generative pre-trained transformer, I need to be able to accurately describe it. Just like Medtronic can't get a trademark on "Heart Monitor" for heart monitors.
If you have ever topologically sorted 100 components connected in a complex graph by hand or found the right spot to insert the 101st, you'd quickly appreciate more help than a compiler check.
There's some strong views about ThePrimeagen in this thread. Just want to share my experience. I've spent tonnes of time configuring Vim, Neovim etc. Its ... a ... mess.

I love both editors and for the love of me, I don't know why configuring them is soooo hard and brittle.

ThePrimeagen videos on Vim/Neovim is by far information dense videos. It took me sometime to ignore his style of presentation and just focus on content. However, the value I got out of watching his videos is undeniable. Knowing his background a bit and how he battled addiction gave me some context. (Sorry can't find that video on his channel now)

Continuing on this topic of Vim/Neovim ...

Leeren Chen (https://www.youtube.com/@leeren_) is pure genius on the topic of configuring Vim. I've never seen another person like him on Youtube, who uses Vimscript to configure Vim to make it work like an IDE (almost).

[1] https://youtu.be/JFr28K65-5E
[2] https://youtu.be/Gs1VDYnS-Ac

TJ Devries (https://www.youtube.com/@teej_dv) videos on Neovim are awesome too (He's core dev of Neovim). But there's lot of gimmicks in his video and it can put people off. His videos with @BashBunni is very approachable in terms of learning about and configuring Neovim.
I described my experiences in a sibling comment. But regarding the discomfort of long hours, I have been using it comfortably for 7-12 hours a day for six days now.

I had to go to the double strap to distribute the weight evenly.

You also rethink where you want to be. My desk is still great, but a tilted back chair with a keyboard/pad on my lap is better for longer hours. That is where I am now!
Toyota's failure is right around the corner. Meanwhile, they've not been able to manufacture enough gas hybrids to meet demand for the last 4 years. Months to years long waitlists on the Prius, Rav4, and so on. Car market changes slowly. What people get today, they will have for 5-10 years. Especially millennials who are struggling to make rent. Toyota doesn't need to catch up to EVs; it's the other way around.
Implementation-wise, yes, but the interface you're exposing is indistinguishable from that of a parser. For all your consumers know, you could be storing the username as a sequence of a 254-valued enum (one for each byte, except the angle brackets) and reconstructing the string on each "get" call. For more complex data you would certainly be storing it piecewise; the only reasons this example gets a pass are 1) because it is so low in surface area that a human can reasonably validate the implementation as bug-free without further aid from the type checker, and 2) because Go's type system is so inexpressive that you can't encode complex requirements with it anyway.
Thanks for the heads up. I would give it a shot out of curiosity following your comments if it were html, but the pdf format is a little annoying.
Some people have to make sacrifices for their families - making money takes time? effort? sacrifice? ZOMG! HOW DARE HE!

Selfishness? sacrificing for family - both on the fathers side to provide but also on the mothers side to take care of the fort?

That's not selfishness. That's called being a good father. husband. wife. mother.

It’s as far away from fantasy as magic can probably be. I think you might like it!

Mini splits are better in this regard than traditional ducted installations.
The One True Wiki[0] says "Used to describe an implementation that needlessly relies on strings when programmer & refactor friendly options are available."

Which is exactly what's going on here. A username has a string as a payload, but that payload has restrictions (not every string will do) and methods which expect a username should get a username, not any old string.

The dual problem would be any function which forgets to accept a ParsedString instead of a string can skip parsing.

Both cases appear to depend on there being a "checkpoint" all data must go through to cross over to the rest of the system, either at parsing or at UnvalidatedString construction.
I’m a big fan of Datadog from multiple angles.

Their pricing setup is evil. Breaking out by SKUs and having 10+ SKUs is fine, trialing services with “spot” prices before committing to reserved capacity is also fine.

But (for some SKUs, at least) they make it really difficult to be confident that the reserved capacity you’re purchasing will cover your spot use cases. Then, they make you contact a sales rep to lower your reserved capacity.

It all feels designed to get you to pay the “spot” rate for as long as possible, and it’s not a good look.

I understand the pressures on their billing and sales teams that lead to these patterns, but they don’t align with their customers in the long term. I hope they clean up their act, because I agree they’re losing some set of customers over it.
While "add a black box complexity extremely resource intensive AI to sort out the dependency trees" is somewhat of a tragic answer to the problem, I think it's the real one we're gonna get - and we'll still be better off than this current clusterfuck.

Hopefully these will also spend the tedious hours pruning unnecessary packages, minimizing responsibilities of each, and overall organizing the environment in a sensible way, then caching that standalone so there's no LLM dependency - just an update checker/curator to call in when things go to shit.

Honestly this is one of the worst problems of modern software and makes 50+% projects unusable. It seems like a very tedious yet solvable problem - perfect for the right LLM agent. Would be a godsend.
Super thanks for sharing Unsloth! :) Highly appreciative and high praise as well :))
I don't know, I've met a lot of devs who've found the "true religion" of strict data integrity and have been reluctant to allow for the messier practicalities of user- and externally-sourced data.

None of them called Stanley, but there's definitely a fairly common pattern I recognise.
