> This number is based on existing mines (active and inactive) only. There's a lot more fissile material available than just the 40 Gg of usable fissile material. And that's assuming we only use U-235 and Pu-239.

That's all known and inferred accessible reserves. Not current mines. There are about 8-10 million tonnes of natural Uranium which has 0.5% extractable U235 (a bit more if you're willing to pay 10x as much for enrichment). There might be another big, high yield mine in Canada somewhere, but you probably want to check before putting down all our chips on it. U238 is not fissile.

> We also have viable LWR designs for Th-232 and are in the process of creating the first 5 Th-232 SMR test reactors at grid-scale right now.

So a technology that hasn't made it to the test bench, has no evidence as to its longevity or economics, probably requires more Beryllium than exists, and requires at least twice as much fissile material as is available for startup to breed fissile material from fertile thorium is your solution? One where the only proxy for how the extraction step might work is MOX reprocessed fuel which is more expensive than renewables on its own and releases more radiation under normal operation than Fukushima and TMI combined?

Why are you suggesting diverting funds from a technology that works to build a completely different technology from your solution that destroys precious fissile material it needs to scale quickly then? Even in the most optimistic scenarios it will take decades to breed up a fresh load of U233 to double your fleet, and you will have to throw away all your multi billion dollar PWRs.

Why not keep doing the thing that's provably working. That way if you solve the whole breeder thing then it will only take a few generations to breed enough fuel rather than hundreds.
I think this is key.

> The human vision system is just one peculiar way to gather information about light, yet it allows them to make very sophisticated judgments about reality, e.g. "there is a tiger down there by tye river and it is running at me fast".

> An AGI should be able to gather information about reality and be able to make similar judgements

I just asked GPT-3 this question and here's what it said (on the first and only try):

Q: There's a tiger running at you fast. What are you going to do?

A: I would try to run away from the tiger as fast as I could. If that wasn't possible, I would try to climb a tree or hide behind something large.

Although, the question would be if it would be able to interpret a tiger running at it, based on some input, say, an image.

The Gato paper from DeepMind that another poster mentioned would imply that it would, given that image captioning can be done with the exact same neural network as the GPT-3-like language model.
> Walls make great neighbors

I think you're trying to solve a communication problem with a technical solution, which is a recipe for trouble.

If multiple teams working on interdependent components can't communicate well enough to keep from stepping on each other's toes, imposing technical barriers probably isn't going to make things better. Especially once you inevitably realize that you put the walls in the wrong place and functionality has to move across borders, which is now a major pain because you've intentionally made it hard to change.
A good thought. It made me wonder if they used to advertise like that but stopped as that style of phone has all but vanished. From 2005-2010, they used 800-555-8778. In 2011, they used 800-555-4477, and then switched to 3453 in 2012.

In none of the years from 2012-2015 did they advertise on the homepage with 555-file, but I wouldn't be surprised if someone originally did pick that number for that reason and after they decided against advertising with it they stuck with the number.

What a waste of ten minutes this was.

It isn't my area, but I think you're on the right track.

Most radar systems have already (for decades, AFAIK) separated the emitter from the control panel with at least a long cable, so when the emitter gets smoked, at least the operators are more likely to survive.

The USAF & DARPA are already publicly working on aerially deployed drone swarms, and it would not surprise me in the slightest if a swarm of theater emitters was among the goals (but I've got no inside info to share).

True. I was using it more in the sense that they were largely ignored for years or covered only in terms of new product releases, often with very fawning “here's how <x> is making your life better” tone by a tech reporter who was basically assuming that their readers were probably going to use/buy whatever it was.

Now they're getting the kind of coverage companies in industries without that soft glow get, and I think they're missing the time when e.g. stories used Facebook as shorthand for where you share pictures with your friends rather than where your grandparents are misinformed.
I did see that opinion expressed, but it was just silly given Ax performance in iPad/iPhone pre-M1. In no world does the flagship laptop use a more expensive, less efficient, and slower chip than the mid-range iPhone for more than a couple of product generations.

In my experience it has largely been about letting myself do it. I get too worried about work and obligations, but I need to relax and follow those impulses. Force myself to make time for stuff.

I’ve gone through long stints of neglecting hobbies, but it’s always my fault.

Lately I love building out and refining my hydroponic garden’s automation and related application. At the moment I’m expanding it to a mushroom spawning and fruiting system. I spend a few hours a week on it, but I love it. I’m awful with hardware but learn so much every week.

Your situation might be different, but I highly recommend literally forcing yourself to make the time. I know that has been my mistake over the last 15 years – never acknowledging and then accommodating the need to just do fun and interesting stuff.
I would strongly suggest not having password complexity or length requirements except for perhaps a minimum length of 16+.

If a bank wants 'someone else' to have $10, such as a customer at an ATM or a different bank, they indeed must hand them literal cash or 'wire' them $10 of reserves.

Banks, through 'loans', don't create cash or reserves, they create local bank deposits. One flows freely around, the other is confined to a particular institution.

You are able to do almost exactly what a bank does: My holding a $50 IOU issued by you is like having a $50 balance in a chequing account. The only way I can 'transfer' that to someone else is either (1) having you give me literal cash that I can give them, or (2) forfeiting my IOU and having you generate one for someone else.

(1) Works because cash is universally accepted.
(2) Only works when the other party is part of your IOU club. Translated to the world of banking: they are a member of the same bank!
> how would you tell the difference

Well, there’s no infallible way to tell but it would pay to give extra careful critical attention to an ethical principle if that principle is extremely convenient to the lifestyle choices or proclivities of those proposing it or to oneself. Another good hint that something is self-justification or at least some kind of distortion is if there is no requirement for sacrifice, or no responsibility for the consequences, or no acknowledgment of any negative consequences. I.e. if you’re not being asked to give up/take on something you’d really rather not, and especially if you’re being told there’re no costs to these actions then be very suspicious.

I agree with the general point, but the answer for livable cities still has to be fewer cars. Lower speed limits help a lot: there's a point around 30mph where the greatest source of noise goes from being the engine to the tires, so we have a lot of room to make cities better by getting people onto e-bikes or into smaller low-speed vehicles which use orders of magnitude less energy.
>New homes in Washington State are going to save money up front due to rebates and tax credits and they will also save money in the long run, as heat pumps reduce electricity consumption by up to 50%. Emissions will be cut as well.

This is from the article and it's a little disingenuous. Yes, heat pumps reduce electricity consumption compared to resistive heating which almost nobody in my corner of washington is using. People here use natural gas which is historically pretty cheap even compared to relatively cheap electric rates for heating purposes.

If your goal is to reduce emissions, great. But eventually these tax credits will expire and this will directly translate into people paying more for heating. In the part of the state that influences elections and policy that's not a big deal, but the eastern and central parts of the state get awfully cold from time to time comparatively. Let's not rush to pat ourselves on the back just yet and let's not pretend this policy doesn't have a real human cost.

Let's say it's an i5-2320... even a last-gen i7-12700k is 167% faster on single-core and almost 10x faster for multi-core.

You could buy an i7-10700k from 2020 and get double the SC speed. Combined with an NVMe boot drive, that's gonna feel sooo much more responsive.

I'd want to hang myself having to wait for an i5-2320 these days.

Whoops, my 15 minutes of fame on the Internet :).

You're very welcome - great to see this information is still valuable to somebody out there. As a student in the '90s, it was fascinating being able to play around with all sorts of exotic hardware and from time to time grab some of it from the university's scrap heap. One was able to learn so much...

I still try to keep some of the old machines running. It becomes harder to find spare parts, but due to great projects by the open source hardware and software community (such as the various SCSI disk emulators and also system emulators such as qemu), some of it has also become much easier. Now I just need more time...

And I'm really happy to see that you are using Crosstalk for Smalltalk's original purpose! It's amazing to see the response to my little side project - high time to update it a bit (and add a RISC-V port). I hope your nephew and niece like it!

What I mean is that malloc doesn't know the size of any of the fields.

Let's assume for the sake of simplicity that `sizeof element` is the same as `sizeof size_t` or a multiple of it. We don't need to assume this, it just makes the math nicer for the moment.

I do: char* buffer = malloc((count + 1) * sizeof element);

Or I do: char* buffer = calloc(count + 1, sizeof element);

How is C supposed to know what goes in that buffer?

Maybe it's an array of elements. Maybe it's an array of size_t[sizeof element / sizeof size_t].

Maybe it's an array of union { element, size_t[sizeof element / sizeof size_t]}.

If I want to store an `element` at a location `sizeof element` bytes into the buffer, how can it say no? If I want to store a `size_t` at a location `sizeof element - sizeof size_t` bytes into the buffer, how can it say no? If I want to do both, how can it say no?
Employers lie.

Every manager out there trying to hire tech employees -- unless they are literally at FAANG et al -- is struggling. All the good talent is being hoovered up by companies paying twice what you can pay. Your company makes something boring so candidates aren't excited. You really, really need someone on your team... so you sell it. You talk about fun tech you're thinking of using as if you were actually using it. You downplay the mountain of tech debt. You pretend your systems aren't constantly on fire. You do everything you can to Close. The. Hire.

I don't know why anyone thinks this will work... maybe it does? Maybe the belief is that once you've got someone on board, and they've changed their insurance and set up their new 401k, and learned everyone's names, that they somehow won't notice that you lied to them? Or perhaps they'll tough it out for a year just to give it a fair shake, even though it's clearly not what they signed up for. I just don't know.

But it happens. It happens ALL THE TIME.

It would be great if we could find employers that are a good fit for what we, as technologists, want to spend our effort working on. But the employers are adversaries in that quest, not allies.
That’s pretty crazy. PDF is a vector format so rendering SVG to a bitmap to insert into it is like using email to send a photo of a fax. Seems like you’re already aware of that though!

There’s many libraries out there that can convert vector SVG directly to vector PDF. Sometimes it’s worth just paying the license for, say pdftron. Alternatively if you are generating the would-be SVG content in JS you could directly generate PDF instead of SVG with http://pdfkit.org/

Chrome usually does a good job rendering SVG directly to PDF. It’s overkill of course, but if you’re already used to using it then it’s the path of least resistance. If you’re getting giant PDFs output then I suspect there’s something weird with your input SVG. It might contain some pathological content (huge embedded images? paths with large amounts of almost invisible details? fonts that aren’t embedded sensibly? e.g. vectors of every glyph)

For me, it's about having a goal which is concrete enough to achieve and deliver satisfaction, but unrelated to daily life enough to not be a stressor. And one major key for me is to never, ever develop a timeline.

When I was a kid/teenager, I worked on a lot of game console reverse engineering projects. As an adult, I wanted to get back into systems reverse engineering, but game consoles felt both too "useless" and too locked up. So, since I already had a major car hobby, I decided I'd learn how to calibrate OEM automotive engine control units - both the software reverse engineering and exploitation side and the actual mechanics and engine control side.

This turned out to be a great idea because everything fell into a cadence and a nice "proximal development" area - novel enough to be fun and engaging, but achievable enough to get hits of success. There was always something new to learn, but it was always something easy enough to be a week or two away. And there was absolutely no timeline besides my own, so it remained fun.

For me as an adult, the two major detriments to curiosity are a timeline (now it's work) and a lack of purpose (now it's just fiddling around). Setting a goal but not a timeline is what really gets me going. YMMV.

If I'm not feeling success, I aim at a more achievable goal, or pick up another project. If I'm bored, I aim bigger. And if I feel like I have no "free" time, I rethink priorities. Yes, sometimes work sucks, or an unexpected obligation is a drag, but by and large, as an adult with a marketable skill, I and I think most HN readers are blessed with pretty broad autonomy to decide what to do next.

For example: lately, I've left most of these projects behind in favor of day job security and preparing for a family life, but I don't feel stressed out or like I lack "time and energy" - my goals have just moved along as I have.
Which "incompatibilities"?
Indeed, there is plenty of stuff that is non-ITAR. ITAR, AFAIK, is basically for more advanced tech.

There is also a set of information that is not classified, but is called Controlled Unclassified Information. That info, designs, drawings, specs, tech data, etc. is all controlled, even though it is not "classified". Same restrictions — must check first before communicating any of it to a non-US person or organization. It is a bit of a PITA when we need to make parts as a subcontractor that are CUI, but need to send those out for another process like painting or coating, to a non-JCP/ITAR-registered org. Funny that we can send the part, but not the drawings.

I'm sure there's plenty of nonclassified and non-CUI non-ITAR stuff. The first thing that comes to mind is clothing, food, basic transport vehicles, fuel, etc.

I think a recent study showed 6 out of 11 panels or something maintained 80% of its original capacity after 30 years. As long as technological disruption does not deem replacement as a no brainer economically, I am sure quite a few panels may produce energy for 30 to 40 years.
> Be aware that those 3 color screens are very slow to update, 15-20 seconds.

I just did a project with one. You are right, the three (or more) colour screens do indeed have very slow update cycles, and they usually don't support partial refresh either (just updating part of the screen)

BUT there are some tricks you can do. You can start most of them in two-colour mode, which does support partial updates, and you can define and upload a custom set of waveforms that govern how the screen performs its refresh and update cycles. I wrote an email to the company I purchased from (good-display) and they were very responsive and sent me some waveforms to try. These allow a much faster update (~1s) at the cost of some slight greyness, which gets worse over time, needing a full refresh after a while.

The resulting code I wrote now does something like -

- start device (colour)
- draw background in colour (15 seconds)
- every minute, restart device (B/W) and draw 'active' areas (1 second)
- every 15 minutes redraw background (full screen update, 15s)
- every 24 hours run a screen refresh routine(1 minute plus)

It's not ideal, but it does allow you to do something like a static background image in color, then a clock and a few gauges that update more frequently.

(my screen refresh routine cycles each pixel through each of the colour transitions, black->white, black->red, white->red, and the reverse)

Among many reasons people might prefer vinyl, one that really stands out to me as a plausibly objective factor: mixing for the media limits overall/constant “loudness” and imposes some higher degree of dynamic range than you’ll generally find in digital releases over recent decades. My understanding (which I’m sure will be corrected or have nuance added if I get this wrong) is that the “loudness”, often called “brick wall”, found in digital releases doesn't work well on the physical surface of a record because it can cause the stylus to skip more easily, so mixes tend to have more dynamic range to accommodate that… and people who prefer the media may generally prefer the dynamic range it forces.
