The linked paper doesn't obviously support the claim you're making here. Maybe I've missed something?

"The median age at menarche was 14.5 years (95% CI=14–15; Nindividuals=128; Nobservations=199), which is within the range of variation of modern populations."

As you said, I can't imagine how this will not go wrong.
This is an interesting article that puts words into what I've been feeling and observing for a long time — at first the transition into Academia from tech felt this way (e.g. wow everyone's programmed to follow the PhD track!) to moving to Australia (wow everyone's so rule abiding and pattern matching; anyone who's attempting to "lead" gets cut down; there's even a term here for it called "tall poppy syndrome)

But lately with all the layoffs it's kind of put a spotlight on tech startups and VCs. These are the smartest group of people who are supposed to escape mimetic behavior... but how do you explain all the VCs investing in me-too scooter companies or BNPL companies or yet-another-meal/grocery-delivery-service, who are now all absolutely wrecked by higher interest rates because these can only really thrive (or even survive) in low to no-interest rate environments? Why would these ever be $1B+ companies in the first place??

Sorry for the rant, it's just that the more you look, the more even the "smartest people in the room" are just performing rituals and it's disheartening and depressing.
The attention mechanism in transformer models also uses this trick - just dot product. I learned this during a long conversation with ChatGPT the other night - an excerpt of its reply to me:

The dot product between the query and key representations is similar to computing the cosine similarity between two vectors. The cosine similarity is a measure of the similarity between two vectors in a multi-dimensional space, and is defined as the dot product of the vectors normalized by their magnitudes.

The dot product of the query and key representations can be seen as an un-normalized version of the cosine similarity, in the sense that it computes the dot product of the two vectors. The result is a scalar value, which represents the similarity between the two vectors, the larger the scalar, the more similar the vectors are.
Yeah, that's the confusing part. Historically that segment of code, much like version of other languages that require variable declaration only at the start of a new scope, is just implicitly at the start. There isn't a linguistic structure that separates it from more normal code that does other tasks; previously it was a compiler error.

One useful thing about the incredible number of podcasts that I've only recently discovered is that you can often find in depth interviews with relatively obscure people or about niche subjects which contain a ton of information that's hard to come by other places.

For instance, a couple weeks ago I was listening to an 20+ year old album I've always loved that doesn't get much attention. I searched in Spotify and sure enough I found a podcast that was doing a multi-hour series just on that album and broke down its history, production, etc.

Another example is that yesterday I was out training for a race I'm running in a couple months and managed to find multiple interviews with the race director, past winners, etc. to put me in a great mindset for a tough day training.
A few rappers came out asking why their producers only want them to sing about those topics.

Reminds me of this old Onion headline:

https://zonewatcher.com is an audit trail and changelog for your DNS records.

It began in 2016 out of some frustration I was having with consulting clients who would modify their DNS records incorrectly, breaking their email and/or website until I was able to get them back online. It was frustrating digging through emails or old technical documents to find the original values before they had made their changes. I wanted a tool that could automatically backup those records to make reverting easy while at the same time notifying me of any changes so issues could be proactively fixed before their business was impacted.

So with that, ZoneWatcher was born. Depending on your plan, we check multiple times per hour and take a snapshot of each zone's records. When a change happens, we record the change and send you a notification so you can review and have the necessary data to revert if it was in error.

This specific paper is only one of several hundred papers from a decade of research leading to IEEE standardization, https://dhalperi.github.io/linux-80211n-csitool/#external

From a 2021 paper on IEEE 802.11bf Wi-Fi Sensing, https://arxiv.org/pdf/2103.14918.pdf

> Indeed, it has been shown that SENS-based classifiers can infer privacy-critical information such as keyboard typing, gesture recognition and activity tracking ... since Wi- Fi signals can penetrate hard objects and can be used without the presence of light, end-users may not even realize they are being tracked .. individuals should be provided the opportunity to opt out of SENS services – to avoid being monitored and tracked by the Wi-Fi devices around them. This would require the widespread introduction of reliable SENS algorithm for human or animal identification.

You forgot to mention that the effect was not statistically significant; the confidence intervals include the null hypothesis.
Computer programs are Turing-complete. How would you ever "modify dimensions [...] to specify what you want the program to do"? The space of possible programs grows like exponentially as you linearily increase the length of the program.

It's trivial to explore visually the space of all possible outputs for a program of length 1 instruction. But how about a million? The output is just gonna be useless noise 99.99999%.

What even is a dimension of a computer program? How many divisions it performs? How many gotos there are?
Ad based payola is running pretty much on every major platform we use now, and SEO is completely defeated by whoever pays the most each day.

Trending topic spots on Social Media apps like Twitter and TikTok are wholly compromised by as based schemes like this, if they arent by botting and other manipulative schemes as well. It will infect AI, and cause untold problems on pretty much every aspect of the net, and the worst part is that as platforms are unregulated and non-transparent operationally, there is no way of telling how much what we see is compromised. We have truly lost a ton of academic value to letting monopolies take over the Internet....

I don't think that value can ever be recovered. Even paying for premium access can't undo the issues we'll face in years to come.
Care to explain this further?
Correct. The true function of a hedge fund is not to beat the market over the long haul, which is generally impossible. The goal is to avoid losing huge amounts of wealth, for people who have way more money than they need. Hence the name --- you put money in there as a hedge against short term losses in equities.
Actually, I believe a deliberate goal was to write something distinctly different from how BitKeeper operated.

Right, that's why I said a "fair market price", not "heavily regulated and taxed to pay for facilities for junkies and pay for drug education". My understanding is that opiates can be produced dirt cheap.

Also I have absolutely no clue, and I doubt there is really even data on it, but there are a lot of people who are dying from fentanyl who aren't opiate addicts at all. One person I knew who died last year couldn't afford healthcare, bought their anxiety meds online, and died in their room from fentanyl. Another person I knew died from ectasy, and having talked around it's a common story.
A manager once asked me to rewrite a bunch of tests written by some former employee, because a security tool was complaining about hardcoded credentials. My guess is that he wanted to satisfy some OKR about how many security issues reported by that tool had been "fixed". Probably the most ridiculous thing I've done.
There also enough power production. To give an example, the Tokyo governor invited people to lower their heating devices and wear turtle necks to avoid exceeding the current capacity.

>My area experienced a hospital overload and that was very debilitating.

Are you sure? Are you really sure? As opposed to just hearing dire warnings? My understanding is that all or almost all of the predicted overload of hospitals never actually happened.

In Wales, for example, Millennium Stadium was converted into a temporary field hospital with 300 beds and capacity to expand to 2000 beds. It was such a big deal that a public contest was held to name it Dragon's Heart Hospital <https://en.wikipedia.org/wiki/Dragon%27s_Heart_Hospital>. However, said hospital never had more than 46 patients at one time, and was closed in six weeks for lack of use!

Even in NYC, which really did see overloaded hospitals briefly in March-April 2020, USNS Comfort treated a total of 179 patients. USNS Mercy treated a total of 77 patients in LA.

> Hydrogen is less efficient, but storage is much cheaper and easier than it is with batteries

And storage is even cheaper and easier with gasoline and diesel. More likely that developing economies will stay on ICE engines until batteries+electricity+chargers become cheaper than ICE.

Hydrogen doesn't have a future outside of location- and weight-sensitive applications like carbon-neutral air travel.
Oh, 99% of podcasts are just terrible. A fav show of mine started quite good, but now... 3+ hour interviews? Why? Because the interviewer just sits there like a sloth and listens to whatever the other party has to say, never interrupting. And from a 3 hour interview there is only (at best) 15 minutes of relevant information, the rest is filler. Even TED talks lately became terrible, I have nothing to tell or I tell you this basic thing packaged as some earth shattering insight in 10 minutes videos, like relevant information is somehow suppressed and just the nothingspeak stays.

good curated content is needed, but goog's search is just plain terrible in this regard. seo optimized pages everywhere with useless recommendations.

Sometimes I find a lot of shows with great content in some forgotten part of the Internet, but these cease to exist after a few episodes... maybe because they saw the initial numbers. and these good people will never come back to create more content, only the brave idiots stay in the arena :(.

Common problems:

- zero editing (respect your audience by cutting the slack and interrupt your interview subject if the discussions veers towards personal things). at least timecode topics in the description. the subject's personal life is only interesting if the person is well known, in the mainstream, or a good story teller, but most of them just like to talk and talk and talk. the interviewer's job is to interrupt the person and make him/her stfu and bring forth another, interesting subject.

- interviewer sometimes is just an idiot, and just regurgitates what the other party has said with different words... mind boggling

- interviewer can't ask proper questions, hard questions. the subject just sits there, like he paid for 3 hours of time and talks about offtopic things.

- good shows drown after a few years or become routine for the creators. There is a podcast about security... it was also quite good in the beginning, but lately it's now all about all kinds of political shenanigans, geopolitics and the like. To be honest it's dead boring, the hell do I care about these high level shit stirring things? I want to hear some insights, expert opinions about the topic.
Not only will I not do pro-bono work, but getting paid in full and on time is a challenge. Even good clients can suddenly ghost you and forget to pay up.
I agree everyone doesn't know how to invest well. Some people even advise stock picking! :)

But the problem of some people not being rich is not simply because they can't invest well. First, obviously, not everyone can be rich. Second, most people suffer from the problem that they don't save enough, rather than that they don't invest well enough.

Yes, some people do beat the market. Obviously a lot of people are playing the lotto every day, and some win. Do they do it reliably? No. Disabuse yourself of the notion that beating the market is ever anything other than luck.

Git Commits on a (Terminal) Calendar
I had been addicted to Github's "green" dots. I hate being an addict, hence I programmed this program. It shows some colouring on days with "git commits" for any specified git repo.

You can change the year ranges, at the bottom of the calendar.py file. Seems better than Github's "Green" dots for me.

EV batteries are recycled quite easily. The lithium alone makes recycling worth it, but pretty much everything about it can be recycled.
They are not competitors, they are complementary. Hydrogen is cheaper and easier to store than electricity is. Hydrogen provides resiliency because of this and is better for long range vehicles because it can be produced and stored relatively easily.

I organized the migration from CVS -> Mercurial at my last job, and finally after several years when it became clear Git was where industry was headed we switched from Mercurial -> Git. After resisting it for a long time and then being forced to use it for a collaborative project with another firm, I have to say git is way better at being a DVCS than Mercurial.

I think, as other have mentioned, that once you truly "grok" git you begin to understand the elegance and simplicity of the system and how its layered. Ultimately git's use of branch pointers was a way better solution than encoding branch data in the commit itself. To it's credit Mercurial did attempt to rectify this later with bookmarks, but ultimately DVCSs are about branch management, and git has always excelled at it.
Edit came with DOS, but it was a handler for QuickBasic. Hence the EDIT was the quickbasic ide with no basic.
My current title at work includes the words "software" and "engineer", and thus I have a natural mutual predator-prey relationship with infosec and compliance/IA.

Which brings me to the point: Compliance isn't just there to cargocult and boxtick. It's there because, left to their own devices, most organisations/sub-organisations will end up, at pinnacle-best, half-assing security.

Compliance is an easy way to force everyone to three-quarter-ass, possibly even hit 90%. It's true that, without compliance, some orgs will hit 99%. It's true that some compliance requirements force you to be less secure than you might otherwise have chosen [1]

But it's also true that for every org that would hit 99% under their own steam, there are a hundred that would do the default ubuntu install, then only patch when something breaks. And that is why I like compliance. I work with our compliance team on lots of things, and everybody ends up winning.

[1] Consider password rules. Some compliance rule says must have a couple funny characters and a mixture of upper and lower case, minimum ten characters. Basically, forces a password that users hit the minimum on, then have no choice but to write down. Compare with an entropy-based measure that would lets users have an essay question, but one that's memorable and has higher entropy. Far more secure, yet rarely how compliance express their password concerns.

Currently, the platform is doing $1,138 in MRR from then managed hosting service and has made over $11k in revenue so far. It's been growing steadily in the last few months but going through a rough Dec-Jan period at the moment. You can see the open page at https://chartbrew.com/open

For the classic HP RPN, it isn't. Numbers are entered directly into the X register. ENTER does several things: it finishes the input, copies the new value in X to Y (shifting the rest up) and inhibits "stack lift", so the stack won't be automatically shifted up when you start entering the next number.

Sounds complicated, but in practice you don't think about it at all.
Those ChatGPT posts where someone gets it to pretend it's a bash shell come to mind, but you are right: this is an incredibly difficult problem domain and you start hitting roadblocks very quickly as soon as you move from cool demo to tool intended for real people to use.

I was one of the backers of https://www.kickstarter.com/projects/ibdknox/light-table/des... and have wanted to see progress in this domain for a long time.

One thing I would add to the conversation is that one of the most potent ways to move this discussion forward is to create technical demonstrations of how this sort of interface could work, presented as video. It's completely unimportant if the functionality is actually working, so long as you disclose this up front.

The goal is to give people with less imagination and hopefully more technical acumen an opportunity to roll up their sleeves and maybe work on making it real.
I understand that someone has to be paid to generate AI, but one of the promises of programming of the last couple of years was that if you could afford a laptop and were smart enough you could contribute to software development by contributing to github and so forth. In practice I don't know how much of that translates into practice (see AWS/cloud/hosting and so forth), but I don't like this future where the only people who are able to program the machines are able to pay for an IDE that has a monthly or per usage cost structure.

The only people who get rich during a gold rush are the people that are selling the shovels. I think that people are tired of rewarding shovel sellers.
