Battery efficiency is _broadly_ linear; 10kg will give you 100x the capacity of 0.1kg of batteries. This isn't the case with generators.

Under 5kg of batteries, engines basically can't compete. The smallest viable petrol engines (you want engines made in large quantities) are around 4kg and need fuel, and so you end up in a situation in which 4kg of engine and 1kg of fuel is as useful as 5kg of batteries (for motors of that size), but every subsequent 1kg of fuel is then also as useful as 5kg of batteries. But you can't really drop this down much, as a 1kg engine is much less useful than 1kg of batteries, and a drone with 5kg of batteries is really a very large drone.

Drones are additionally typically very small and light, with mass at an absolute premium. A typical quadcopter will weigh under a kilogram and have maybe 200g of batteries for 20-30 minutes endurance. A drone with a 2.5m wingspan will typically have room for maybe 1-2kg of extra payload, and an engine will not fit into the battery slot.

Furthermore, they are extremely sensitive to weight balance issues.

This is to say, once you're in the world where you want chemical fuel, you might as well design a drone for it, rather than trying to retrofit. The mass of retrofitting will mess up your prior drone design, and petrol changes the dynamics of what you're trying to do enough that you might as well just do it all differently.

Essentially, if you're making a 1-10kg drone, you want battery. If you're making a 10-20kg drone, you might want battery, you might want petrol. Above 20kg, you probably want petrol.
Hydrogen fuel for merchant ships isn't going to happen. Despite some issues with toxicity and pollution, the industry seems to have settled on ammonia as the main replacement for fossil fuels.

We might actually get more "nuclear powered" civilian ships, in a way. The reactors will be on land, where they can be properly guarded. And the heat and power will be used to manufacture carbon-neutral liquid fuel.

I was aphantasiac(?) most of my life and I self discovered similar techniques to what they discussed in the Reddit while learning multivariate calculus. I was trying so hard to visualize the integrations and using the “fuzz” I see when I close my eyes to infer the shapes then one day I could actually see them in my minds eye. I never applied the technique to other things because I didn’t have the same motivation to practice that induced my first breakthrough but I am pretty confident the technique works. The plasticity of the brain is remarkable and it’ll adapt to what you need it to do if you work at it.
I'll hold out for the teleportation-based version so I don't have to go through the effort of opening my mouth.
Impasto. The wiki article has a Van Gogh as the main picture.

I never really liked it, but I might just have been subjected to a lot of amateurish pretentious use of the technique. It kind of screams "I am a painter", but you need to back that up with something or it's just annoying and closer to "I am making a mess". Possibly good training for cake decoration after you give up art and take up baking.

Picolisp - what a weird thing. I have to admire the temerity of a guy who in 2023 is still team "dynamic scope is better."
I use a single node microk8s instance mainly so I can stay familiar with syntax and things for work rather than an actual high availability system.

But I use Portainer and store my files on Github so Portainer can auto-update a deployment if I submit a code change, so kind of rudimentary CI/CD which could be fleshed out more with some GitHub Actions probably.

I use iSCSI mounted storage from my NAS on the host and k8s volumes storing configs there. Actual app data is on the NAS accessed via NFS from the relevant apps.

So a new deployment is usually test locally on my laptop, once it's good commit the code to github and either let the deployment auto update or go to Portainer and do it manually if it's a new deployment. Ingress traffic is done via Cloudflare Tunnels deployed in k8s.

I keep most apps in a single namespace called prod unless they need more than 1-2 pods. If I was doing this again I'd use a namespace per app, I do use a dedicated namespace for anything with a Helm deployment or needs a lot of pods (e.g. Immich)

>TURTLES AND DEFENSE

>Introduction

>At Terrapin, we feel that our two main products, the Terrapin Turtle ®, and the Terrapin Logo Language for the Apple II, bring together the fields of robotics and AI to provide hours of entertainment for the whole family. We are sure that an enlightened application of our products can uniquely impact the electronic battlefield of the future. [...]

>Guidance

>The Terrapin Turtle ®, like many missile systems in use today, is wire-guided. It has the wire-guided missile's robustness with respect to ECM, and, unlike beam-riding missiles, or most active-homing systems, it has no radar signature to invite enemy missiles to home in on it or its launch platform. However, the Turtle does not suffer from that bugaboo of wire-guided missiles, i.e., the lack of a fire-and-forget capability.

>Often ground troops are reluctant to use wire-guided antitank weapons because of the need for line-of-sight contact with the target until interception is accomplished. The Turtle requires no such human guidance; once the computer controlling it has been programmed, the Turtle performs its mission without the need of human intervention. Ground troops are left free to scramble for cover. [...]

>Because the Terrapin Turtle ® is computer-controlled, military data processing technicians can write arbitrarily baroque programs that will cause it to do pretty much unpredictable things. Even if an enemy had access to the programs that guided a Turtle Task Team ® , it is quite likely that they would find them impossible to understand, especially if they were written in ADA. In addition, with judicious use of the Turtle's touch sensors, one could, theoretically, program a large group of turtles to simulate Brownian motion. The enemy would hardly attempt to predict the paths of some 10,000 turtles bumping into each other more or less randomly on their way to performing their mission. Furthermore, we believe that the spectacle would have a demoralizing effect on enemy ground troops. [...]

>Munitions

>The Terrapin Turtle ® does not currently incorporate any munitions, but even civilian versions have a downward-defense capability. The Turtle can be programmed to attempt to run over enemy forces on recognizing them, and by raising and lowering its pen at about 10 cycles per second, puncture them to death.

>Turtles can easily be programmed to push objects in a preferred direction. Given this capability, one can easily envision a Turtle discreetly nudging a hand grenade into an enemy camp, and then accelerating quickly away. With the development of ever smaller fission devices, it does not seem unlikely that the Turtle could be used for delivery of tactical nuclear weapons. [...]
I think it is more likely the developers of operating systems are just not aware of some obvious things. E.g. it took them years to introduce a dark mode and to adapt the color temperature of the screen to something warmer during the night.
Which model? And could you share an example of some of the things you've asked it and gotten wrong answers for?
There are two models with full-size four-door crew cabs and 8' beds, and they can work in most US suburbs. I think it's less about whether it's manageable and more about the aesthetics. The front-rear proportions on 8' trucks just aren't great.
Now that you mention this, removing color from the exercise and focusing on the spatial features made the exercise incredibly easy. Trying to visualize color seems to be more difficult.
If you actually cared about safety you’d require airbags, crumple zones, licensing, insurance, and crash testing for cyclists. You’d also ban them on roadways with speed limits far above what a human can reasonably propel a bike to, since dV is a major driver of accidents and lethality.

Expecting a 15MPH ~250lb bike with none of those features to interface safely with 55MPH 5,000+lb traffic is moronic. You’re better off building parallel infrastructure and taxing cyclists to pay for it via licensing.
This is so cool and just brings me a lot of joy :)

Also, I've been working on a project (non-commercial) that looks down on people and have found existing models don't work super well from that angle so thank you for publishing your work on Roboflow.
That's a terrible idea. Biking on the sidewalk should be illegal for everyone except young kids. Sharing the sidewalks is dangerous when the speed difference between the average cyclist and the average pedestrian is something like 10 mph.
The technical details of the quote are correct, but FWIW I'm no longer working on the GHC bootstrap. It's fun for a while but the lack of interest in the Haskell community and the general high level of ridicule and hostility from the rest of the software world towards all things GNU / free software / bootstrapping have kinda turned me off the whole computer thing.
I tried implementing the four versions:

16bit: https://gcc.godbolt.org/z/6G38YxcGr

32bit: https://gcc.godbolt.org/z/vEzf9h1jo

I thought it's interesting how "div" is used in 16bit versions, whereas for 32bit versions the compiler optimized all of them to use only imul.
That's why I care so much about WebAssembly (and other sandbox) features that can set a strict limit on the amount of memory and CPU that the executing code can access.
I guess this is why most places change prices more gradually. If they made it 1.10 for 3 months then 1.20 for 3 months etc I bet people would have dealt (assuming it's still the cheapest coffee around).

Yeah I am in this camp as well. I can also do things like, after the apples are smashed together I can see heir bruises, rotate them, make 2 more bruises, etc. while keeping the bruises in their same spots.

It’s actually really annoying because when I’m stuck on a problem I essentially solve the whole thing in my head. I just see all the issues with possible solutions and back them out.

I wonder if it drives my boss nuts because I can go a whole day basically committing nothing, and then bang out the solution very quickly.

I actually have been actively trying to “just start writing, see what pops out” and it isn’t coming very naturally, which is kind of obnoxious.
What happens in Russia or China if you viciously criticize their leadership?

Most of the “free world” is at least comparatively free compared to the rest. No it is not black and white but it’s definitely light grey vs dark grey or black.

There’s a reason places like the USA, Canada, etc continue to be the most desirable destinations for immigration while you see very few people trying to get into Russia or China. Only people trying to get into those are fleeing much worse places or in the case of Russia have drunk certain brands of kool-aid.
I obviously have no insight into whether or not the company engaged in whistleblower retaliation or intimidation practices. But that is a different argument from whether or not the headline accurately interpreted the statement.
Lame delegations are a scourge, like untreated venereal disease; often accompanied by a similar refusal to acknowledge externalities... or that there's any problem at all: works for me! But the DNS community, or bright people trying to do other things with DNS (I'm one of them), often bring it on themselves.

For instance let's just go down the "until they find a server that isn't lame" rabbit hole: let's look at a server which isn't actually authoritative for the domain it serves. Maybe they're all lame, sorry.

It could be a recursive, and it should be obvious that AA isn't present in the response. But in the real world, people with their own root are forced to lie in order to publish data in the public (root) namespace. This is baked into server configs as forwarding zones for those too lazy to recompile BIND to always return AA. Not that anybody checks, the DNS still works, so why bother? But the root (ha ha, pun!) of the problem is the obsession with One True Root which is staunchly defended by ICANN, kind of like the petrodollar.

Or it could be authoritative, but not for the zone which it is properly delegated. Take my ISP, please. They impersonate the people who delegate their /17 in reverse DNS; I assume it's because they're too lazy or incompetent to manage 128 /24s. Fun fact: sometimes recursives subsisting on this diet of excrement report that they ARE authoritative for the delegator's /16! The delegator doesn't care, they block email reports from their own /17 so no worries about anyone cleaning up after GG Allin finishes his show.

But the DNS authoritahs bring it on themselves: "Additionally, the queries to lame delegated nameservers represent additional load on the network, and at the incorrectly delegated nameserver. For example, incorrectly configured domains represent 12% of queries to GoDaddy nameservers: one out of eight queries received by a GoDaddy nameserver is a lame query, a query for which the GoDaddy nameserver is not authoritative." Cry me a river. Qname minimization can effectively double the number of (unprimed) queries required to resolve a name. Coincidentally, qname minimization issues requests which are intended to fail (hoping for SOA) and NS requests which are unnecessary under the archaic recursion algorithm which they vigorously defend by farting in a different direction. Needless to say, qname minimization doesn't work well with lame servers.

I could go on, but I won't.

It is generally believed that the trip is part of the mechanism for healing

Interestingly, you can have trips without psychedelics, like with holotropic breathwork, and still get the benefits

> The resurgent interest in psychedelics is partly driven by huge unmet need. The World Health Organization estimates that about 280 million people worldwide have depression

It’s almost like the same system that makes people depressed, wants to create a pill to wave it away, so that people can keep doing the stuff that makes them depressed, but without getting depressed

Fuel cells are ultimately just fancy batteries, they could electrolyze their output water when they "recharge". But in practice, our cars are all lithium BEVs, not FCEVs. There are some hydrogen forklifts, whose niche is that they're used 24/7 and hydrogen refills are faster than recharging batteries, but ultimately fuel cells make no sense at car-scale or below.
Also, human brains come pre-trained by billions of years of evolution. It doesn't start as a randomly-connected structure. It already knows how to breathe, how to swallow, how to lean new things.
I'd suspect you could do that with Open3, but if you are, why not just read the file and process with Ruby instead?
From my perspective, it's not useful to dwell on the fact that LLMs are often confidently wrong, or didn't nail a particular niche or edge-case question the first time, and discount the entire model class. That's expecting too much. Of course LLMs constantly don't help solve a given problem. The same is true for any other problem-solving approach.

The useful comparison is between how one would try to solve a problem before versus after the availability of LLM-powered tools. And in my experience, these tools represent a very effective alternative approach to sifting through docs or googling manually quote-enclosed phrases with site:stackoverflow.com that improves my ability to solve problems I care about.

Because it turns out the manager just starts giving away the coffee for free, so whatever numbers somebody was pulling from the sales system were obviously incorrect.

The problem with "running numbers" like so many other metrics is that they are usually run by MBA types who have a weak grasp of math and don't really understand the customers' psychology (often work in corporate offices that are nowhere near the stores).
To be fair, that’s not the only way to start a comment to make it sound LLM-esque.
Can you tell me more about your Portainer setup? Does it just update your app from an image or is it checking out code from a git repo on deploy? This approach sounds very interesting
On the other hand, it also gives the consumer more power over the wages of an employee than any other business. Do you think your fast food or retail employees are under paid? Teachers? Fire fighters? Too bad, you have almost 0 power to change that (and some of those positions have policies / legal prohibitions from accepting tips at all). But your local restaurant servers? If you think they're not paid enough, you have the direct ability to make a change on that front. Sure you probably still need to convince everyone else to do it too, but on the other hand, we can see that working in the fact that the "expected" tip rate has risen over time from ~10% to ~20%.

In fact, now that I think about it, since tips are a percentage of the bill, I wonder if tipped wages keep place with inflation better than retail?

Not to say that this is a great system overall, but I also find the mindset that's worried about tipped wages to be odd, because like I said, if you think they should get paid more that's entirely in your control. No one needs to wait for the boss to decide to hand out raises or make market adjustments. And most of my friends who worked tipped jobs weren't bothered by the tips per-se as they were with the times when work was slow. Sure they griped about stingy tippers, but none of them ever had a top complaint of "man I wish I could just make $8/ hour flat rate instead of getting tips"
Is there any indication in the quoted statement that the retaliations were initiated or supported by the company management? If not, the headline remains inaccurate.
This is a tool to manage environment variables. People use .env files with dev/local env var values in Git repositories for a good reason. They won't stop doing this.
Show HN: 'justinstall' from any GitHub repo, file URL or local url
Basically it detects your system and downloads the correct binary from GitHub releases. It also installs .zip, .dmg, .pkg, .deb, .tar.gz and just regular binaries. It can also detect installation scripts from README files or release notes.

Currently in beta but I've personally found it very useful. It supports all operating systems to a degree but hasn't been tested on windows.

I'd love some feedback on it! The end goal is to be able to run justinstall [anything] and have it just work
Amazing. Any chance of Top Hats as a premium upgrade?
Cycle exact? Sure. But what are the odds you need that for some x86 software made in 2014.

Otherwise, via translation techniques, getting 80% of native performance isn't unheard of. Which would be very fast relative to any such Ivy Bridge server.

Transitioning away from x86 definitely is feasible, as very successfully demonstrated by Apple.
I've accidentally dropped the key at the same time as slamming down the trunk. The key happened to fall into the groove that the trunk goes in, and the close button got pressed by the closing trunk. This was a fun one to explain to the AAA guy. I'm sure lots of other ways are possible too.

I've bought a phone with a big battery so I could do exactly what the GP said, always charge between 30-80%. But that means I'm cutting half of the potential energy in the battery.

I'm lamenting the fact that we have to do this even though film capacitors can be drained from 100% to 0% without damaging the capacitor or reducing its capacity. This is far closer to how you want an energy storage device to operate. Aside from the fact that film capacitors store about a thousand times less energy by every metric.
I wonder where you learned that. To my knowledge, there are only very few artists who work that way.

Factorio is a bad railroad simulator because you cannot do grade separation (bridges or tunnels). This means all of your rail networks are artificially limited to being planar graphs which kills your throughput.

OpenTTD allows grade separation at least but imho is inferior to Simutrans which ensures cargo and passengers have destinations and will not use your network unless you can path them to their destination.

Because OpenTTD doesn't have this it devolves into forcing cargo or people to travel the longest possible distance for the most money, instead of to where they actually want to go.

Simutrans-extended is something I'm really hyped for because the simulation of passenger desires is even more in-depth than the original.

The most satisfying rail network for me is one that has both complex form and function.
Os that due to some thermodynamic scaling trade off or just a matter of fault tolerance (i.e. we cant machine them well enough at that scale to be as efficient)?
