Hi mikewarot,

As a general rule, Luneburg lenses need to have a diameter at least equal to the wavelength of the frequency they are designed to operate with. Because of this, Luneburg lenses are more cost-effective at higher frequencies, making them particularly suitable for applications in the GHz range.

It is possible to develop a Luneburg lens for LoRaWAN, and I am currently working on a DRC check for various wavelengths
I'm surprised they still exist.
Just wait until you see what crooks can do with Telegram, or Megaupload, or the Linux kernel, or Microsoft Excel.

That used to be the case - but it's rapidly becoming standard to be directly connected to fibre. I believe that something like 60% of UK premises have a fibre connection available and I expect that all the providers will push folks off copper as fast as they can.

Because copper is a pain in the arse compared to fibre (for the provider). For the consumer copper has one key positive that fibre just doesn't - it works in a power cut.
What methodology? The article references a lot of studies. Which are you referring to?

I'm not sure what it's called, but I think my father has it! A bit over a decade ago, he had severe abdomen pain but refused to go to the doctor because he had similar symptoms a few times over the past several years and it was never successfully diagnosed before it went away after a day or two. This time though, he got to the point where he was severely jaundiced, and my mother forced him to go to the hospital. It turned out that this time, his gall bladder was filled with stones to the point where it was about to start overflowing into his liver, so they removed it and he's been fine ever since.
The existence of layoffs has little bearing on if there is a shortage of skilled workers. A layoff in marketing does not imply that a shortage of surgeons cannot exist.

From a quoted article in this piece[1]:

> unmarried and childless women are the happiest subgroup in the population

Isn't this kind of scary from a sociological and demographic perspective? It would seem to indicate that we've built a socioeconomic system with self-terminating incentives.

I consider myself very liberal/libertarian and individualist vs. collectivist, and I have a daughter, so I'm (angrily) unsympathetic to ideas that even hint at restricting women's freedom on this basis. I'd easily prefer the gradual dissolution of western civilization to my daughter being trapped in an abusive marriage with no right to divorce, being forced to give birth to a child she doesn't want, and so on.

However, all that aside, it does seem like a serious bug in our system. I wonder how we can we flip this statistic without restricting anyone's freedom?

I could easily see this going the other way. Life long single people develop strong social networks that they keep investing in into old age. Married (and with children especially!) couples invest less time in their social network, in old age they then have many fewer friends when their children leave and their spouse passes.

(I'm not sure this is true or not, but seems plausible. I agree with the author that we should get better data to resolve these questions).
The links don't seem to be obvious.

Thanks for notifying me; I have now updated the blog post, making the links explicit.
Yeah - there are colour codes you can use to find the pair that you want to connect, they are arranged in a mystical system of binders. It's like a map.
could you share any links you have? I'm fascinated by the whole saga of Havana syndrome, plus I live in Seattle. I'm on the skeptical side but my mind is open.

Using (absolute interest rate - inflation) as the real interest rate is a good enough approximation, but the present value of the last EMI payment would be impossible to obtain.
I wonder how much this line of thinking serves to reinforce the very issue it's concerned about.
I've been buying used QC25s, there are plenty of parts available to refresh and keep them working. I think everything in them is off patent now so theoretically someone could start making compatible main boards and then the user base would be able to fully decouple from Bose's product roadmap.

This is impressive Matt, and I love the design system GDS has developed, but I'm not sure they want non-government services to use the system. From the second link you posted:

> Use this design system to make *government* services consistent with GOV.UK

Emphasis mine. Are GDS aware of this work? I am in no way affiliated with GDS by the way.

--

I'm always wary of this kind of thing not being on a gov.uk domain, which in this case is entirely appropriate because it's not in anyway official or endorsed by GDS. Not for any direct phishing/crooks concerns as raised above, but because it waters down the impact of this kind of thing always being on gov.uk domains.

--

Edit: I'd be _very_ surprised if GDS don't take issue with you having "GOV.UK" in the name given that it is no way associated with gov.uk
True for SIP. That does give a somewhat accurate number. For knowing the present value of the last EMI, it doesn't help, though.
Local news will still put on a crying puking fentanyl cop, and angrily defend the story against every doctor and scientist that objects. They don't care if it's true; if you don't believe it, you're anti-cop and pro-drug.
> Some kind of directed energy weapon from an enemy state.

Suppose you are a nation-state, hostile to the USA, that has developed a directed energy weapon. Do you test it:

A) on your own citizens (whether willing, deceived, or coerced),

B) on citizens of some remote, poor, and/or war-torn country that is unlikely to retaliate against you,

or C) on diplomatic personnel from the country with the greatest military and intelligence resources by far, and with a proven history of bombing or invading other countries on both true and false premises?

I had never heard of Havana syndrome before, and I have nothing to comment either way on whether the physical symptoms are real and/or have a common cause. But the idea that an enemy state is using a secret weapon prototype to... randomly give headaches to American diplomats? Is bizarre, to say the least.

What good will reading the code do you when by your own admission you can't understand it?
It’s just that awk has a concise syntax that can make for some really quick one-liners in your terminal prompt. Why spend a minute or two in Python if you can get an answer in 15 seconds instead?
Highly intelligent people are still susceptible to conspiracy thinking. It only takes one person who is delusional or read about Havana syndrome to influence everyone else. Then they believe it and soon it is “well known in community”.

But they can’t know it was directed energy weapon because there is no evidence just rumors. There isn’t evidence that directed energy weapons exist or cause those symptoms. Does everyone even have the same symptoms? How did they determine the area? How did the rule out chemicals or other causes?

Finally, testing in Seattle doesn’t make sense. It is too dangerous to be discovered, and easier to test where won’t be noticed. Also, using public means can’t collect reliable results.

Awesome!

Here's my feedback from an initial rough pass:

* Provide some references for what a Luneburg lens is. Not everyone will have the same context as you and will need to look up what a Luneburg lens is (like I did), distracting from what your contribution is. Once the context is provided, articulate clearly what your contribution is (which maybe you've already done).

* Provide example pictures of the lensing effect on different (input?) waveforms. The Wikipedia article has some pictures [0] [1], and other references [2], that, while needing context to understand, at least get some of the point across and provide an anchor point for further investigation.

* Have an online demo so that people can immediately play around with it

* Provide a quickstart section that shows how to start their own instance, including the call to firefox/chrome to open the web browser to the appropriate page

* I don't know what's up with that video but it's having a hard time playing back. Further, it takes at least 12 seconds of seeing input field filling and "progress bar" like animations before anything is actually displayed. The payoff should be within 5s (preferably less) of the start of the video to communicate what you want to folks. Technical details of what each field does and how to fill them in can be relegated elsewhere, like in a wiki or 'how-to' doc.

* Have a screenshot of the actual RF antenna being created instead of what looks like an AI generated grid field. Use a screenshot from your application.

* Communicate the limitations of the approach. You're talking about optimizing for SLA 3D printing but will this antenna actual work if 3D printed? Does it need to be out of metal? Some communication about the limitations is fine and, in my opinion, welcomed.

* Discuss some applications or motivation for creating the application (target audience, use cases, etc.). As it stands, it seems like it's very cool but a bit unmotivated

Admiral Raymond Spruance of the World War 2 US Navy was known as very calm in a crisis; he was very serious about getting enough sleep so that he was well-rested during any battles. When other officers would stay awake for 36 to 48 hours at a stretch, he would read a novel and get sleep because he knew he had enormous responsibilities that needed him at his best.

He also walked 8+ miles a day, even when at sea he would make sure he walked around the ship, usually with some other officers to discuss any pertinent issues of the day. Walking is great for turning over problems in your mind, or even just daydreaming to give your subconscious mind "space to work".

No one needs consent to learn from public information. If an AI can look at your drawing and code, then later draw a correct elbow and make the right API call for someone, they have benefitted without taking anything away from you. To try to stop this process because you think you deserve royalties and consent every time someone uses a fact they learned from you would be absurdly entitled.
This article doesn't do a good job of getting at the main points of Valiant's book Educability, in my view. You can see some of them in e.g. this talk he gave here: https://www.youtube.com/watch?v=W4fIoLGjFtM

He makes various arguments in the book that I disagree with, two of which I've put below. On the whole I think it is directionally correct though, and worth reading.

The first quibble I have is about humanity's most characteristic trait. In the book, he writes: "The mark of humanity is that a single individual can acquire the knowledge created by so many other individuals. It is this ability to absorb theories at scale, rather than the ability to contribute to their creation, that I identify as humanity's most characteristic trait".

I don't think that ability to acquire knowledge from other people is our most most characteristic trait. Creativity is. Learning is a form of knowledge-creation, and it is a creative process. We don't passively "absorb" theories when we learn from someone else. Instead, we actively look for and attempt to resolve problems between our existing ideas and the new ideas to create something new.

Another thing I disagree with is when he touches on AGI. He makes the argument that "we should not be fearful of a technological singularity that would make us powerless against AI systems". This is because it will "asymptote, at least qualitatively, to the human capability of educability and no more".

This is reminiscent of David Deutsch's argument that people are universal explainers, and AGI will also be a universal explainer; there is nothing beyond such universality, so they will not fundamentally be different from us (at least, there is nothing that they could do that we couldn't in principle understand ourselves).

I think this is true, but it misses something. It doesn't address the point that there is a meaningful difference between a person thinking at 1x speed (biological human speed) and a person thinking at e.g. 100000x speed (AGI running on fast hardware). You can be outsmarted by something that wants to outsmart you, even if you both possess fully universal educability/creativity, if it can generate orders of magnitude more ideas than you can per unit time. Whether we should be fearful or not about this is unclear, but I do think it is an important consideration.

His overall message though, is good and worth pondering:
"Educability implies that humans, whatever our genetic differences at birth, have a unique capability to transcend these differences through the knowledge, skills, and culture we acquire after birth. We are born equal because any differences we have are subject to enormous subsequent changes through individual life experience, education, and effort. This capacity for change, growth, and improvement is the great equalizer. It is possible for billions of people to continuously diverge in skills, beliefs, and knowledge, all becoming self-evidently different from each other. This characteristic of our humanity, which accounts for our civilization, also makes us equal."
awk is also not hard to understand, scroll through the Wikipedia page for a few minutes https://en.wikipedia.org/wiki/AWK#Structure_of_AWK_programs

It runs an action for each line in the input (optionally filtered by regex). You get automatic variables $1,$2... for the words in the line split by spaces.

The syntax is almost like a simple subset of Javascript. Builtin functions are similar to C standard library.

If you have input in text that is separated in columns with a delimiter, and you want do simple operations on that (filter, map, aggregate), it can be done quickly with awk.

That's all you need to know about awk.
The United States leaned so far into support of marriage from both the church and state that we've entirely isolated ourselves into nuclear families and in the process lost the support of the "village". We are raising children in these "strong homes" (fortresses?) as you say and not in strong communities.

You ask what happens when children can't count on a mother and father being at home for them? Well I might also ask what happens when abuse perpetuates because societal pressures make marriage difficult to escape?
Something like that.

The Dragonbox author reports[1] about 25 ns/conversion, Cox reports 1e5 conversions/s, so that’s a factor of 400. We can probably knock off half an order of magnitude for CPU differences if we’re generous (midrange performance-oriented Kaby Lake laptop CPU from 2017 vs Cox’s unspecified laptop CPU ca. 2010), but that’s still a factor of 100. Still a performance chasm.

You can likely get some of the performance back by picking the low-hanging fruit, e.g. switching from dumb one-byte bigint limbs in [0,10) to somewhat less dumb 32-bit limbs in [0,1e9). But generally, yes, this looks like a teaching- and microcontroller-class algorithm more than anything I’d want to use on a modern machine.
