The Reasons of Arnold-Chiari I, Idiopathic Syringomyelia, Idiopathic Scoliosis
Hello, I know that this site is for technical things. But doctors community is so closed and not friendly). I deciced to ask question here. Maybe someone has the experience or can give some usefull info.

There is institute in Barcelona which concludes that the reason of the diseases: Arnold-Chiari Syndrome Type I, Idiopathic Syringomyelia , Idiopathic Scoliosis, disc protrusions and herniations and others is
abnormally tense Filum Terminale. The description on their site: https://institutchiaribcn.com/en/diseases-we-treat/filum-disease/

They suggests the surgery to cut filum terminale in the coccyx region. This relax tension and stop progress your disease.

The problem is that the traditional approach for Arnold Chiari 1, for example, is decompression surgery in the occiput. Most "traditional" doctors say that approach in Barcelona does not work, they just make money. But cannot give 100% proof that it does not work. Many Barcelona's pacients report that after their surgery have good improvements and quality of life. It's hard to find where the truth.

Is it possible that tension of filum terminale can (hypothetically)causes , for example , scoliosys or disc damages, or chiari 1?

In site they write that the first person who gives attention on relationship between tension and scoliosis was McKenzie, a neurosurgeon from Toronto. If that is true why future investigation was not prolonged in Canada or USA and were just forgotten.

Now I found McKenzie article and am trying to read and understand it.
The article http://www.boneandjoint.org.uk/content/jbjsbr/31-B/2/162.full.pdf

Any info or your expirience in such diseases or expirience in Barca will very usefull.

Thanks.

But the big statistic is that autism in all of its forms is around four times more common in males than females. In other words the genetic components have a biologically sex-based component.

Does this account for the fact that women tend to be underdiagnosed? I have read that female autistics are very often a) not diagnosed and b) pressured to learn social skills anyway simply because they are girls.

PS: I am a girl. I could spot the bottom figure in the top, though it took me a few seconds. I have an unusually strong math background for a girl (perhaps especially a girl my age). I think it is ridiculous this is a test for autism. Why on earth is this is a test for autism?

I am pretty darn sure I am not autistic. My ex husband and both our sons probably all are and I taught all of them a lot of the social skills they have. My ex husband once told me that he was good at the technical aspects of his job, but his ability to manage people once he was promoted to that level in the military was largely rooted in what he learned from being married to me.
Additionally, this sort of referential database could be quite useful in other pursuits. Want to map mentions within works to research how culture addresses itself? It may also capture a larger market segments, people who are interested in one topic may find they share interests with the author in another topic.
Rent-seeking regulatory capture shouldn't be called entrepreneurship at all. America's mania for privatizing government work does indeed encourage that form of rent-seeking, as does any other system in which a government awards contracts to private enterprise to get work done. One thing many businesspeople and founders (outside of Palantir) are unaware of is that a single government contract can be several orders of magnitude larger than their wildest revenue projections.
Hasn't this always been the case in every scientific field? It seems like every other week there's a new study that proves something everyone intuitively knew. The point of doing the research is to gain actual scientific data (e.g. mathy stuff, as you put it) via the scientific method that will add to a preexisting body of knowledge.

I always find it really interesting how people handle crisis situations. Some stop in shocked horror. Others run, both away and toward the crisis. Some people get shaken up, while others can remain calm, and even turn commanding and controlling (not in an egotistical way) and people follow their orders, sometimes not even knowing the person.

Of course, what I've noticed is that once the crisis is over, the calm people start kind of doing their own processing and freakouts. I guess that's what courage is - freaking out later.
Nope. Just a banal statement of fact.
We're safer and more connected than they were back then. That means more sensitive to smaller risks, and better able to talk & hear about risks of all sorts.
How do I mix them? I said the alternatives to rockets are nukes or a space elevator, both of which, for Earth to space launch, are beyond current feasibility. Ditto with most of the ideas on that Wikipedia page. Air breathing only gets you 10% of the way and the others are limited by our materials.
>Ionic can help us get lithium-ion past cobalt and completely eliminate it with alkaline

There are already lithium-ion chemistries that don't use cobalt, eg. lithium iron phosphate[0]. This has lower energy density than lithium cobalt oxide, but it's safer and survives more charge cycles. It's already commercially available. Solid-state alkaline might be able to beat it on cost, but it's a long way from commercial availability and lithium ion technologies keep improving, so that's far from certain.

From your linked blog post:

> The situation is particularly ironic because the argument that has been advanced for discarding Lisp in favor of C++ (and now for Java) is that JPL should use "industry best practice." The problem with this argument is twofold: first, we're confusing best practice with standard practice. The two are not the same. And second, we're assuming that best (or even standard) practice is an invariant with respect to the task, that the best way to write a word processor is also the best way to write a spacecacraft control system. It isn't.

Well said. I think I'm going to have to hold onto this argument for a rainy day.

Someone once said that your boss isn't paid more because he's better/works harder, but because only 1 of the row below can be promoted to boss, so they have to make the pay amazing, so everyone below works really hard for the company to try and get promoted.
That is very much a rich person's answer. It's certainly "more efficient" for the wealthy if they can drive poorer people from their homes when the rich find it convenient. But that's not what it feels like if you're on the other end of it.
How effective is a named sanction? Certainly the Russian government could simply rename these people if they needed to. It's not like they're going to travel to the US where the US could apply biometrics, since they'd probably be arrested with or without this act.

What everybody can agree with is that AMZN stock price is massively overvalued.

Amazon is on low margin retail business. Amazons market cap is $475B. Assuming 10% ROI and 3% profit margin, Amazon must make $16 trillion in revenue some time in the future to justify the current price.

US retail sales are $5 trillion.

Total retail sales across the globe are $22 trillion.

Even if Amazon continues to grow at current pace, it runs out of markets to dominate before current stock price can be justified.

Bezos announced that he is unloading $1B per year. Smart man this Bezos guy.

If that's how you read it then I feel like you missed the entire point.

> This is a non-statement. Replace 'engineering' with science, medicine, finance, customer service, politics, retail, programming etc., and it will sound as correct.

Again, I'm feeling like you missed the point.
These people never want to acknowledge the fact that programming used to be near-universally "women's work", right up until dudes decided it was cool and stole it from us. CS admissions used to be more than 40% women!
> True diversity may be the recognition of the fact that all of us are not equal.

The proposal is that we recognize this fact, and realize that the mindset in which there must always be "the proposal," to fix "the problem," is misguided. Particularly when you have ideals like diversity, and equality which, the author argues, are at odds with one another. The rest of the essay is an argument that the two are, indeed, at odds with one another.
Could someone please give some context on this?
What I'm saying is either this rant will put women off to tech or bring more in. Their decision to pursue this industry is what matters. Do you think this will be looked at positively by women currently outside tech?
Exactly, GA suffered very badly during the AI winter to be more specific, but it's coming to the scene again. In fact, GAs don't need gradient information at all. If you want to do some weird stuffs like evolving deep networks, multi-objective optimizations or large scale black-box optimization, GAs (and friends) are the only way.
Took me a few seconds too, but I didn't think to rationalize it as "though it took me a few seconds", I thought "wow gee I got it in only a few seconds".

Why should spot all? The question was not "count all versions of this form". Only find the picture. One time.

Moreover, this is a skill related with spatial intelligence and finding patterns, not with autism.

> So if I spot it then what does it tell me about the spectrum

Probably nothing - except that you don't see a box in perspective, looking at the diagram below, the "shape" synthesis in your brain might be different.

Your mind isn't taking the "box" below as a 3-d box in perspective automatically, which is what a filtered perception should have (just enough detail to be useful, not enough to overwhelm you).

If you, like me - see a square and two parallelograms instead, it becomes trivial to ignore the colours guiding your eyes on the top image.

Yellow square ... yeah. Red blue parallelogram to the top right of it, yeah ...

Whether you perceive reality as a mixture of abstract shapes or whether your brain smoothes over it to form meaningful structures (like a box) is relevant to autism (one assumes).

Reassembling fragments of perception is a very well exercised part of my brain, because it is necessary for me to operate - but beyond that, it gets easier to reshuffle them before reassembling, which is what this is test is about.

It is a test of being "mentally bilingual - reality and perception", which is necessary to overcome being somewhere on the spectrum and be functional.
It's history the way Fortran is history. Most people in most situations do not use it. Specific people in specific situations still use it, and it's still the best tool for that job.
> Why are there so few women in IT?

...

> This is because they are good at localised skills, especially attention to detail. This is very useful in lab work, coding and IT.

IT is not the entirety of tech by any means. And if we're going to make large stereotypes, a bulk of IT work is about empathizing with users at least as much as attention to detail.

Coding is not the entirety of tech, either. Knowing what to code is more important than knowing how to code it. It may not have been, decades ago, but a significant amount of the code that people need has already been written and the challenge is to find it and deploy it / integrate the library / fork the open-source project / etc. An engineer that prefers to write code for the sake of writing code is generally not productive for the business (and probably counterproductive, by generating what will soon be legacy code).

I'm not sure what "lab work" means here but I've never seen that term applied to software engineering.

Also, autism is not the only way to be detail-oriented. The article is trying to claim that there's gender imbalance in autism, and autistic people are detail-oriented, and detail-oriented people are good at IT, and therefore there should be gender imbalance in IT. This is simply fallacious and illogical.

Autistic people are not your shield.

That only works if everyone has equal bargaining power. In the fruit-gold machine world, sure the price of gold tanks, but as long as there are people willing to pay more for gold than others are able to pay for fruit, the poor can't eat fruit anymore. That's bad for them.

The free market doesn't do what's best for everyone, it weighs people by their ability to pay.
This sort of sentiment is just absolutely outrageously incorrect. Go and look at any proper study or report on house prices, and you will find who it exception that it is land use regulations that are responsible. Sam Francisco is a prime example, though I could just as easily cite London or Auckland. The supply of housing is restricted by tight land use regulations, and so of course the prices go up. Anybody who wants to blame free markets for the obvious, foreseeable effects of regulation is clearly blinded by ideology.
Right now Amazon is showing two kinds of recommendations: 1) "the customers that bought this also bought…". That one can show you books that are totally unrelated to the book you are buying or even to your actual interests. 2) the "Sponsored products related to this item". I don't see why they couldn't substitute one of them for "books the author of this book recommends", or something like that.
This seems a prime example of Linus being a pretty awesome maintainer. Blunt, but really just honest on messaging.

Or was I supposed to read this differently?
It's simple: there are just a few defining traits for each race: skin colour, hair, shape of the eyes and nose. There are just few genes that control those.

There are also hundreds or thousands of genes that control other traits, such as genetically conditioned diseases, immune system, IQ, physical endurance, character traits, etc.

That's why if you measure diversity by number of genes you can get such a seemingly paradoxical result.
In big cities it seems like there are more full-time drivers, but my experience out here in Cincinnati, Ohio (with a population of ~300k in the city and 2.2M in the metropolitan area) we have mostly part-time drivers.

This is my first time reading extensively about the Magnitsky Act -- isn't this very clearly a Bill of Attainder aimed at specific individuals? It also seems to be in direct violation of the fourth amendment, though I think it might be ambiguous whether it applies to foreign nationals.

At the very least it seems like each seizure should be individually heard and approved by a judge.
I wouldn't read too much into individual examples. However, in composite, these little tests do reveal how people think overall.
But I used to know GAs don't need gradient information, right? The algorithm is supposed to discover the gradient by itself, if there is any.
I don't understand why so many discussions about this in the context of engineering / software jump to the idea that diversity is just have 50:50 of characteristic X and characteristic Y. Or why everyone makes assertions about what we know to be a very important and divisive issue without first stating what our own understanding of the words we are using actually is.

I think I have a very different idea of what equality and diversity means to this person (or that soon to be ex-googler), so I'd like the opportunity to talk about it with them, reach the same page of understanding, then talk some more.

In my view, it isn't as simple as 50:50 men and women in the room. It's about removing all barriers to that being a possibility that we can. Specifically, making sure we all have the same equality of opportunity, burdens of expectation and freedom of expression. Recognising some groups lack one or more of those things is a good start. Recognising some groups (deliberately or accidentally) monopolize those things to the detriment of others is a better start.

I guess people will bend further to justify the status quo than they will to better it.
It pains me that the article speaks obviously of a female manager. But then often the writer unwillingly mixes it up, and makes her a male. It smells a bit like gender bias.
Assuming you are male, that may be the real sex difference: Girls aren't supposed to be good at anything, they apologize for not being "good enough" even when they perform as well as the guys and then if they are excellent, no one believes them.

(I think this is literally true, but it is intended as sort of humorous observation so maybe imagine there is a winky here and interpret that to mean "look, this is an injoke of sorts!")
Not until I stop writing out poetry drafts. I find a mix of writing, typing, reading aloud and recording my verse helps take a rough draft into something more coherent and whole.

Each of these methods must use varying parts of my brain as I find they often find improvements that others miss, but I always start with pen and paper, often getting a good 9/10s of it made that way.
Let's assume average income = x

So, rental income from 3 houses = 1.5x

Even if we assumed that all three homes were owned outright, you'd be on the hook for property taxes, maintenance, and utilities for each house. About half of my monthly expense minus mortgage is on these three line items.

Therefore, 1/2 of 1.5x goes straight to property taxes, maint, utilities leaving your income at 0.75x. You have to pay your own rent/expenses out of this.

Living off renting isn't foolproof at the levels you suggested.
The final straw was Jobs trying to oust John Scully. John Scully said me or him. Board went with Scully. The point is that a lot of his actions that directly let up to that made him a dick. In Jobs case, his destructive behaviours didn't help the bottom line.

Being a dick screws over motivation, colleague happiness/satisfaction, increases turnover, etc. These things have an economic cost. Being a dick can cost your workplace lots of money.

It is somewhat related, in that as part of that programme South Africa built the RSA series of space launchers, doubling up as nuclear-armed ICBMs, with technical assistance from Israel.

The 'R5b' space programme would've used the RSA-3 and RSA-4 launchers, with the former designed to place a 330 kg satellite in a 41 degree low earth orbit and the RSA-4 able to place a satellite into a medium earth orbit.

As part of this, the Greensat earth observation satellite was designed and built, initially for military surveillance and later for civilian uses.[0]

Four RSA-3s were built, three were launched on sub-orbital test trajectories from Overberg Test Range, and the fourth remains preserved at the South African Air Force Museum at Air Force Base Swartkop, complete with mock satellite in the final stage.[1][2]

Had the programme not been cancelled in 1990, it's likely that South Africa would've been able to launch Greensat by 1992 or 1992. However, it was prohibitively costly and of questionable benefit for a country slashing budgets after the end of war, preparing to end apartheid, and acceding to international protocols on the use of ICBMs and nuclear weapons. Attempts were made at commercial sales, but the programme was never really cost effective.

Tip for the diagram in the article: Look for just one of the shapes that comprises the bottom figure in the top figure, and you've found it. The front face is the easiest to spot.
