My last semester was marked by operating systems (Unix V6, which you can find the C code for still floating around) and interpreters - in which we implemented a simple python like language called "Wumbo".
It's a pity that this sort of feature is done with a custom ad-hoc HTTP protocol instead of using a message queuing protocol like AMQP or STOMP. Those are designed for this kind of thing and already have libraries available, they avoid the need for busywork polling and avoid the need to break work up into batches client side. You should just be able to submit messages containing work to a queue and then let the broker inform you when new responses arrive on the response queue if you're connected. If you're not connected they buffer up for a while until you reconnect and drain the queue.

The advantage of that approach would be that latency could be minimized or tiered. Instead of a single "one batch with maybe up to 24hr latency" the offer could be a series of tiered queues with different SLAs and costs, and you can pick which you submit your work to depending on how important it is.

I wonder why they went for this custom JSON/HTTP approach instead. Maybe they feel that they can't expect developers to understand anything other than POSTing JSON.
> Why do most people work?

People work for satisfaction as well as money. You even give your own examples of a non-financial motivation before you got "wise". Only caring about money sounds like hell to me. Look at everyone that chooses a calling or career that doesn't pay well like teaching or much of our health system. Please don't assume they are stupid people making bad decisions - they often know exactly what they are doing (e.g. my extremely smart teacher friends) and part of their gross income is the non-financial payoffs of the job.

Personally I think society depends strongly on people chasing satisfaction from their jobs, and sectors which only chase the money have a rather sick ambiance (although perhaps necessary sectors?). Every good tradie is proud of their work.

There are a lot of taker/user jobs and bosses - perhaps avoiding those is the trick if you want satisfaction.
This was my first thought. With projects like the "awesome lists of..." stuff too, I feel those do a pretty good job of distilling the more popular or in demand projects to browse through. Then you've got places popping up around those, like https://selfh.st/apps/ (which I just discovered via HN a week or two ago)
Indeed, I feel less worried about my 50w solid state laser cutting head from China than I would a 5w laser pointer, as the 50w laser head has a 5mm focal distance and the head has a 50mm square housing, so it mostly obscures what it is lasing and it defocuses quickly.
I wonder if you could have similar results from licking a 9v battery
Well if it’s so overpaid why aren’t you doing it? Have you ever talked to a nurse? The stress they go through is absurd.

There rarely is any useful information in opening sentence or paragraph of a typical article, so as with banner blindness, it's excusable to read the article and still miss it.

Maybe. But this is not unlike the libertarian ideal of letting the economy crash in 2008. It can create a tremendous amount of short-to-medium term suffering based on the faith that the long term outcome will be better. I’m of the mind there are probably better solutions that mitigate a lot of that downside.
Big fan of Rewind (despite the impact on battery life!). My favorite part of it is that everything is verifiably local. I'll take an inferior AI model to shipping recordings of everything I see/hear to someone else.

Hard pass on Limitless. I don't care how good the encryption is, sending this kind of thing to anyone's cloud is a nope for me.
Did you also remove some roles so that it looks like you're younger? I've heard that is the only way to get interviews these days as senior cvs are getting thrown out (too old, too expensive)
My case is classic: hearing damage at one particular frequency (from one stupid event). Apparently, the neurons got bored, and decided to create their own input at that frequency.

As others gave said, you get used to it and rarely notice it. I suppose that is more difficult if it's not just constant noise.
I think it's more likely that it's enough to satisfy Musk. Tesla as a company is probably hurt much more by selling the Cybertruck than if they hadn't made it and had focused on a normal car.
That’s not two columns. There’s a lot of the latter in the former. Louder the cheerleader is, often the more they are compensating.

The largest cohort are people who are unaware of what the sacrifices of service members are, even in peaceful times, more out of ignorance than anything else.
It would be impossible to do E2E encryption unless the transcription happens on the device (I assume you mean the wearable).

Even with that, you will only access the transcript and still need an AI model to get meaningful info.

This device wouldn't be suitable for anyone with little privacy concerns.
I have a CNC plasma cutter which I use for making robots, and have also worked with laser cut metal. The laser cutter is so, so much more precise. On the plasma I cut some gear teeth with 5mm pitch and they’re okay for a coarse positioning system that doesn’t rotate continuously. On a laser you could cleanly cut 1mm pitch gears for continuous rotation I would think.
If you own the means of production, is it really “stealing” though? /s
Holy crap this works! I've the loud high-pitched type all evening and i've just used your method to reduce its volume significantly! Thank you!
>But starting on a hill in a conventional automatic with a torque converter also involves either rolling back a bit or pressing the accelerator a bit before releasing the brake.

Felt deeply in San Francisco. I think newer cars rollback less than older cars. Either way, it is unnerving when driving in Lombard street.

You can't pay me enough to drive in SFO in a stick shift.
I'm not an expert, but as far as I know, the logic is just a failure of long-term planning to dominate over short-term planning. "I know I shouldn't smoke, but this one cigarette will feel so good".

It depends on how you use your fingers to count. Most of us are taught to raise one finger, then raise another … one-by-one until they are all raised in order to count to ten. We can also use our digits as digits and then each finger can be one bit: closed is zero and open is one.

This scheme allows for binary counting and even generalizes for people with different numbers of fingers. Lose a finger? You can still count to 511. Gain two fingers through genetic manipulation? Now you can count to 4095!

Maybe the binary coded decimal fans can reduce their counting space and count to 99 with two extra bits left over for holding their pencil!

Base 12 or maybe “base 10” where 10 - 1 = B could more efficiently be encoded in the same way so that one can still count to BB and have two bits left over!

The world is chock full of possibility. In the meantime, we have really cheap calculators available so we can divide 7 by 3 and not have to cut one of our fingers partially off to express the result.
THANK YOU,

This is displaying dichotomous thinking. I don’t think the only choices are a) waste their time with vigilante justice and let them be beaten/raped/killed and b) allow the extortion and scamming to continue by capitulating.
> (3) the removal of turn signal and shifter stalks.

I remember reading about the removal of the turn-signal stalk, (moving it to buttons on the steering wheel itself) and IMO it's just bonkers.

How the heck is someone already in some squiggly turns or a roundabout supposed to identify and touch the correct spot without taking their eyes off the twisting road or compromising their grip on the wheel that wants to return to the neutral position?
Nothing here has anything to do with creating a “CPU” in 2 weeks. In the Twitter authors defense he says “chip” not CPU and I didn’t see where he claimed to have actually successfully completed anything in 2 weeks just that he was “challenged to.” This article is pretty garbo.
You're suggesting a hosted Postgres offering isn't "as portable" as a very standard solution?

This isn't DynamoDB here, this is about as standard as it gets. I'm failing to find the supposed lock-in being talked about here.

> Don't look too close at spinning wheels failure modes.

It's a sealed turbine, not a "spinning wheel." It's failure modes, while internally destructive, are often limited to the device itself, and trips are much easier to install and utilize in this path.

Dead short DC failures have a tendency to destroy nearby equipment and start fires as well. You're also going to need a bank of capacitors, so you've multiplied your failure rate for each capacitor required.

> there isn't enough technical difference to justify either of the options

There's a massive amount of difference and AC is obviously justified.

You don't seem to be aware of the history of the power grid and how we've arrived at the technology we have.

Reminds me of a seaQuest episode, in which they had to hit a black market for an A/C chip for their sub; the captain was complaining that they can't get it through procurement, but were he to ask for a nuclear warhead, he'd have the weapon helicoptered in a hour later.
GNU Hurd.

Also, why it's inadequate?

"Unix 2.0" which is basically plan9/9front, uses namespaces, cpu, auth and so on 'servers' to authenticate users and even shared devices over the network.
Interesting idea. I want this to exist. It's needed now that many projects have left github. The closest thing I can think of to what you want to make are those "awesome x" repos on github which list projects related to x (e.g.: https://github.com/mbasso/awesome-wasm)

It needs a memorable name like wesource or youcode.

You'll probably want a way for maintainers to claim a project (like google allows businesses to do on maps). Community management in general seems hard.

The other hard part will determining relevancy. What do you show on the homepage?

Ad-supported or donation-based?

Look to large wikis and public resources like everymac.com for inspiration maybe.
You can open the door just fine with the app that acts as your key as well.
I've programmed in C++ for years and this behavior has never been a problem I've seen in any real codebase that I've worked on, and I've never heard anyone complain about this behavior. And that's without ever seeing this behavior explained explicitly until today.

That's because the current behavior is intuitive to any programmer who understands the core design decisions of C++. Default parameters don't change the signature or name mangling of a function, and they have to be specified in the declaration rather than the implementation. So without being told, it's clear that compliers must handle them at the call site.

At the call site if you only know the object is of type Shape, the compiler can't possibly insert the default value for type Rectangle. Heck, in the general case Rectangle might be defined in a separate DLL or .so file that doesn't get loaded until run-time. So there's no possible way for the compiler to know its default value here. So without being taught, C++ programmers know what behavior to expect, and they're right.

That said, over time the use of default parameters has gone from encouraged to discouraged, largely to promote code clarity and explicitness. So it's a less important feature now than it was in 1997.
EDIT: Eh, maybe not. I see it's describes as the "exhaust plume" elsewhere...which really does suggest the fusion is taking place outside the motor. So I remain confused.

----

> Secondly, how are they turning the fusion into thrust? Causing fusion in the exhaust stream after it's left the motor will make it hotter, but how does that heat couple to the vehicle? In a pulsed plasma thruster, thrust is produced from the reaction against the acceleration of the plasma by the magnetic field. How does fusion affect that?

I think (?) the idea is that it's being added to the exhaust stream before it's left the motor and in particular while it's still in the magnetic fields. This would indeed be like an afterburner, where the additional fuel is added to the "exhaust" of the turbine but while still inside the engine.

(The fields accelerate both positive and negative charges in the same direction. It does seem like you'd need a positive-negative bias to the typical output velocities in order to use the Lorentz force here, but maybe I'm confused.)

> By contrast, electromagnetic thruster ions are accelerated by the Lorentz force to accelerate all species (free electrons as well as positive and negative ions) in the same direction whatever their electric charge, and are specifically referred to as plasma propulsion engines, where the electric field is not in the direction of the acceleration.[1][2]

No, I think -Wl,--gc-sections still produces unwind data for the functions that remain. I suppose you could use the strip command on relocatable (intermediate) .o files. But the most common approach is probably building with -fno-exceptions -fno-unwind-tables -fno-asynchronous-unwind-tables. Or perhaps the toolchain defaults to that when building C, which is an odd configuration for GNU/Linux because pthread_cancel actually uses unwinding in C (and -fexceptions avoids an unprotected function pointer on the stack that is called even on the non-canceling code path).
LLMs don't work on words, they work on sequences of subword tokens. "It doesn't actually do anything" is a common explanation that's clearly a form of cope, because you can't even explain why it can form complete words, let alone complete sentences.
Perhaps it is in Apple's interest to allow additional restrictions on the GPL. They're certainly not required to distribute it.
I think semantic search will be important, open source project documentation can be a bit obscure so it can be hard to find what you're looking for with a cursory Google search.

I want to build x that does y using z, where you your database has x y and z - but maybe x y and z's own github pages don't explain what their code is capable off as well as you do. I think that would add value to what already exists.
The guy featured in this article is just part of the marketing arm of a bigger public awareness and enforcement trend that is (slowly) reducing demand, if you will, and making it easier to either find them or cut them off from communication services in the target country.

When we tried to install solar panels, one of the MANY roadblocks our coop put in the way was that we had to opt out of additional charges for carbon credits before they would begin processing the solar installation.

So because we applied for a solar inspection to have solar installed, we were automatically enrolled in a program that costs us more money, for their carbon offsets. And they were selling it to us as if that's just the same as us installing solar panels.

Garbage. And that was just one of about a dozen different blocks they have as part of their process.

If I lived somewhere with other utility providers, I would tell them to fuck right off.
It's all sent to OpenAI for the LLM processing, so you'd better make sure you're happy with them getting text transcripts of everything that ever shows up on your computer screen.

There's a reason pretty much everything that does not require low latency replies avoids stateful networking - everything from RSS to video streaming prefers stateless polling designs because it is vastly easier for both parties to implement and scale. Meanwhile, I couldn't name a single system in widespread use built around a MQ paradigm in its public interface, except for actual MQ APIs, and many of those (e.g. from AWS) are still built on polling for the reasons just described

> ”probably didn’t see a lot of upward mobility”

There was a case in Brazil recently where a medicine student in a top university embezzled from her graduation party funds (she was at the party committee) to invest in cryptocurrency, make profit and return the money to the fund keeping the profit. But she lost money on crypto. Then she tried to gamble (playing a lot of money on the lottery) to earn what she lost. Lost everything and got caught. Expelled by the university.

She had a lot of potential for upward mobility as a doctor from the most prestigious school in Brazil. Still did it.
It's encrypted, but they have the keys. Wouldn't want anyone else to access the data without paying the toll, after all.

That would have helped a lot! Using a high-conductance device to transport heat away from the hot side before switching to lower-conductance devices for heat rejection. All I can say is that my thermal philosophy wasn't as robust back then, and I also had an irrational fear of heatpipes :)
Oh! Thanks for the info. This felt like the same people.
> Since certain norms aren't as intuitive/automatic, it's as if everyone else is secretly playing a game with a set of unspoken barely-explained rules.

That's exactly how I feel lol biggest reason why I minimize my interaction with most of the society

Anyway, I think that people in general assume that others behave in a way similar to theirs, which works if you're average, but doesn't if you're not. You can see this when two cultures with opposing attitudes meet: both of them think "obviously I'm normal, it's them who's acting weird".
Not vital to the larger point but:

> to have any hope of achieving this goal would require the addition, every year, of 630 gigawatts of solar photovoltaics and 390 GW of wind starting no later than 2030—figures that are around four times as great as than any annual tally so far.

But according to Bloomberg:

> developers deployed 444 GW of new PV capacity throughout the world in 2023.

So rather than 25% towards the 2030 goal we are 66% there on PV.

Bloomberg continues:

> It says new installations could reach 574 GW this year, 627 GW in 2025, and 880 GW in 2030.

So hitting the target 5 years ahead of schedule by this estimate.
I think the type of improvement you’re talking about falls under the category of ‘reconductoring’, or capacity improvements to existing deployments. That can help, but interconnection and new distribution is, I think, a much bigger piece of what’s needed, and for that, we need to get all over the place.
As far as I am aware, I don’t hold values or principles that are abhorrent to foundational ethical guidelines. If I ever do, I don’t expect any sympathy from others as I reevaluate my views in light of new information and grow as a person.

Yes. So basically RAG is RAM for human and AI to interact with each other.
Doing no RAG is on one side unprecise (for lack of context) and on the other side inefficient (think of non-RAG as having a more general attention).

Inefficiency (in other words, higher expense)is sometimes even easier to perceive for decision-makers
