to answer your question yes i do manage my own portfolio.

i use my metatrader for technical analysis, it charts are my source of information as opposed to the traditional news services. plus meta trader has a get feature of setting alarms and bells to notify me if something has turned the way i expect it to.

i am not a day trader, but i check the selected company stocks which i am targeting in a particular market on the daily bases, and look for the movement and opportunities in the particular market segment or a particular stock in a market section. And then make a decision whether to jump in or dump it. its simple plus if you add more than two or three information sources or adviser's it gets all confusing to make a decision.

i believe in keeping it simple.

The volume of patients is irrelevant, the FDA could easily open up the market to competition by bringing in suppliers that were approved by other nations with similar medical standards. They could even compare the statistics regarding complications arising from the drug, it's not exactly like there would be a shortage of applicable data. Why they choose not to do so is beyond me, perhaps other drug companies would fight back against such a move, even if it was only limited to generics.

On a side note, regarding those 2000, there's evidence that toxoplasmosis is under treated in the US, particularly with regards to pregnant women.

I agree you should be able to opt-in to a safety level. For example most programmers do expect signed integer overflows to follow 2s compliment behavior - regardless of what the standard says.

There really seems to be a large disconnect between the tool writers and the users of said tools. I've had countless discussions with compiler writers where we've essentially talked passed each other. The compiler writer arguing from a legalistic (and dare I say moral perspective) that the programmer must not write undefined code, and myself from the perspective that developers do write undefined code and we should therefore find a way to handle it in a safe way. Perhaps even by standardizing more than we do currently.

In reflection its not unlike the drug legalization debate.
AFAIK the linux kernel does use the RDRAND instruction set from example Intel. However, it uses it as a mix-in source of entropy and is not the sole source of the csprng seed.

I personally think this is a good approach, as it allows hardware TRNG to increase the quality and quantity of entropy without being able to own the internal generator.
A company without AI in their pitch today is like a company in 1995 not having a web strategy. Time will tell if AI is as sticky as the web.

Citation needed because honestly, I've never heard of this and I think you're confusing it with something else. I've been using computers since the introduction of the original IBM PC and have had to spend a lot of time dealing with memory issues over the years.

"Extended memory" drivers were a common thing back then but that was to circumvent the 640KB/1MB limit of DOS and they had nothing to do with video card memory. In that era few people even knew how much memory was on their video card because it was rarely a concern, most of the time it was just barely enough to hold a single frame buffer, typical of most VGA and "Super-VGA" cards.

Extended memory is that which is beyond the boundaries of the original IBM PC design: https://en.wikipedia.org/wiki/Extended_memory

It's not video card memory in any way. If I recall correctly the video card memory was often mapped into the 640KB-1024KB memory zone, but using that for system memory was futile since you'd be unable to see anything on screen.
The categorisation issue is a good one to raise, it would be something to iron out. You may be interested in this video, the speaker mentions a couple of solutions to the categorisation issue, as well as a bunch of other implementation issues they're trying to address:

> Chris decided to report his discovery to the State Department and let them contact their Mexican counterparts in the spirit of cooperation. When he got no meaningful response, he reached out to the State Department’s Office of Mexican Affairs, who told him they would forward his alert up the chain. When that still didn’t achieve the desired results of getting the database secured, Chris contacted the U.S. Secret Service, Department of Homeland Security, and US-CERT

I definitely am all for doing the right thing and I might make a best effort in the same situation, but that's pretty gutsy. My overdeveloped sense of paranoia would tell me that contacting these agencies would put me on all sorts of lists I wouldn't want to be on. Who knows how easy it is for "There is a data breach" could become "I have your data, meet my demands".

>I think you might be misunderstanding how wikipedia works.

I don't think so.

>It most certainly should NOT fairly represent minority viewpoints of editors. There are quite a lot of editors who believe in weird conspiracy theories, but that doesn't mean they should be given prominence in the article.

The problem with only accepting "reliable sources" is that that leads, essentially, to only parroting what is frequently heard in the mainstream media. The articles are thus only "fair" if you consider the conventional treatment of the topic at hand "fair". If you believe this, most likely you are just terrible at detecting bias and should avoid editing WP anyway because you can't spot NPOV violations to save your life. I think it's a mistake to claim mainstream publications are de-facto sources of truth and/or that they should always be favored over other sources.

Perhaps the most egregious demonstrations of the absurdity of WP's source policies are that Wikipedia will often reject primary sources because a) they aren't published by a mainstream outlet or b) they believe the primary source is "too biased" to comment on an issue involving itself.

The reality, however, is that no matter how right you may be, even if you have prominent mainstream sources to overcome the site's contrived reliability test, which is in fact often the case, it really comes down to which camp has more time to edit war (admins included here). This is how we get badly biased articles on even slightly controversial subjects; WP is not really self-policing, it's just mob territory. Of course, if we believe that the relevant mob's opinion always comports with reality, there is no problem. I believe that believing this, about almost anything, is naive.

>I've never seen any kind of PR company on wikipedia, although I don't tend to edit company articles.

A single Google search will bring you face-to-face with the evidence. While a lot of people seem to state that it's important to "not edit the article directly" but rather suggest changes on the Talk pages, it's safe to say that even among the people who repeat this mantra, it's frequently ignored. Like SEO, no matter what you say about how you use it, you have no option here but to compete or die. You'll also find results in Google's Top 10 that ignore this rule and offer to either help you edit your WP page yourself or take money for editing and monitoring it for you. WP is a staple of online "reputation management", which is something every company does, whether they acknowledge it or not.

Oh, I think we absolutely are individually choosing this state. It's just that we're responding to incentives that are basically emergent behavior resulting from the choices of everyone else.

You always have the choice to ignore incentives; that's why they are incentives and not compulsion. But ignoring an incentive means that you accept not getting the benefits that are offered by that incentive. A lot of people forget that they can do this. You don't have to optimize your life to pick up every little goody that comes your way; you always have the option to say "Yes, that's nice, but I care about other stuff more."
Only this assumes that the music industry and its impact on culture is a constant.

Katy Perry might has "equaled Michael Jackson in terms of number of hits in the Billboard Hot 100" but those hits now came with much less sales than in Michael Jackson's era.

Ever worse, at MJ's time, if you had a hit, everybody heard it -- the channels were few and not that fragmented. Nowadays you can be Katy Perry, have a #1 hit, and half of the country wouldn't even know it, much less know how to sing it.

The cultural impact of Katy Perry is thus reduced to some teenage (or early teenage) kids, and tabloid gossip people reads and forgets that very minute.

And of course now there are 100 other things for a young person to do, between gaming, mobile, social, internet, anime, etc -- back then music was much more crucial.

>If you think these aren't as significant as [fill in your favourite act from decades past] then you're not the right demographic.

That's the thing though. You didn't have to be in the right demographic to think the Beatles significant. And even in the same demographic, you can have like 90% of people not giving a shit about Rihanna, whereas you couldn't for the Beatles.
I didn't RTFA, but I'm wondering why Fortuna[1] hasn't seen better adoption or excitement. I think the BSD team made the right approach of making /dev/random|urandom both a CSPRNG, which if seeded and mixed is an unlimited source of high quality entropy.

Fortuna also has the benefit of mitigating damage from a compromised generator. If the generator is compromised it's very difficult to rewind the RNG output and perform a history attack (is that even the right word for such a thing?).

I agree, your sense of paranoia is overdeveloped.
If one starts to tease out any of the arguments around what the existence of general AI would imply, you notice that within this hypothetical terrain, nearly all the abstraction used in the discussion leak very heavily to the point of being difficult to even use.

For example, what is benevolent? Many people would claim that we have failed to "program" the entirely human intelligence of government leaders and corporates heads to act beneficially to large swathes of humanity.

But this just highlights to me that there is little agreement on what "beneficial to humanity" means.

If Margaret Thatcher is correct that society does not exist, only individuals, perhaps the task of "beneficial AI" is to encase us each in our own virtual reality bubbles where we can specify the world we want to live in.

But if we take a different view, that maintaining some sort of human society is necessary for the growth or maturity of people, then beneficial AI would have to work to help people relate as a society.

And in either way, creating "beneficial AI" implies working out beforehand what is beneficial to human, something that we haven't to do before now simply through lack of the god-like powers needed to impose such a conception.
Structuring a Series AA Fundraise for an Easier Series A
"The cryptographic processing of the entropic data is implemented with a
well-known and well-studied deterministic random number generator: an SP800-90A DRBG as defined in [2] – naturally excluding the NSA-sponsored Dual-EC
DRBG."

"The concept of the LRNG allows the selection of the used DRBG and
the backend cipher implementations at compile time."

Is SP800-90A DRBG really state of the art?

According to Wikipedia "the publication contains the specification for four cryptographically secure pseudorandom number generators for use in cryptography." Without Dual-EC it's still three different DRBGs. How good are they? Is there anything better?
"and once you have those defenses you can use them against malicious Tor traffic and no longer need to block its legitimate users."

Exactly, my favourite types of conversation are usually about some specific thing that is not necessarily "deep" at all, be it a programming language feature or the troubled life of some historical character, or the reasons behind the prevalence of some observed phenomenon (like the colour spectrums of movie posters, say). When discussing something fairly simple with an intelligent generalist, it's usually really stimulating not because they have some deeper perspective, but because you get carried away and stumble upon new ideas and crazy thoughts that you would never have come across on your own. Discussing philosophy proper is usually quite boring and not stimulating at all - that's what you have books for imo.
It would be nice if there's a department you can trust to handle your report in a way that's both confidential and reliable about getting results.

Picking up the phone and calling random departments is how you get in trouble. All it takes is one person to scream "hacker", which is not unlike yelling "fire" in a crowded building, and you've got yourself in hot water even when trying to do the right thing.

If there was a number to report security issues of this sort, or an email address if they're that savvy, it would go a long way towards encouraging people to report serious issues.
I've seen 2 things there 1. electric and 2. 50 people nothing to do with 50x time size. The Solar Impulse can lift up about 5 people as it is (if there was room), scaling it to 50 might might be possible but cargo, and at the weight you were talking about no sorry not going to happen.

Solar Impulse is a marvel of engineering, and the fact that during on of the legs of the flight a single person flew the damn thing for 6 days straight is an attestment to human ingenuity and courage but there is a very very big difference between flying 50 people using electric aircraft (again electric not specifically solar) in 50 years to flying 50,000 of lbs on solar power.

We already have electric aircraft capable of 1.5-2h of flight scaling those up on electric power alone without solar might actually be easier as you do not inherit the weight of the solar panels.
Efficient fuel cells and ultra light batteries / nano super caps could potentially make electric flight possible within 50 years but again relying on solar to transport cargo long haul no sorry not happening.
Given how the Department of Homeland Security thinks a tiny bottle of mouthwash is a threat to national security, I wouldn't trust them to understand what a computer does.

look i do understand your fear of getting the experience mediocre field, but lemme tell you some thing there is no such thing like a mediocre experience, you have to get up and do something even if it is a chore your boss asks you to instead of doing nothing because all you learning will go away in six months to a year, and you wont be able to write even 50 to 100 lines of code because you have lost touch of it, it happened to me, and believe me it is scary.

plus you have to take initiative to learn and grown, your boss or who ever you work under does not have time to sit with you ever day and guide you like a counselor. he has errands to run every day.

and about not being able to switch, so all you need to switch to another field is a reliving letter and an experience letter. and you can switch. i went to work for a bank for a while after my first failed startup. there will be no problem.

Turing test
For VW, that was easy because the test setup was known and very rigid.

If you randomly check, say, power usage and latency of the on-board RNG (ideally combined with high-resolution IR recordings of the CPU), it will, at least, be harder for the CPU manufacturer to install a backdoored RNG that is active most of the time (but one that only gets activated after receiving some trigger, say a specific instruction sequence would still be virtually undetectable)
My molecular biologist friend's comment on this is pretty on-point, so I though it was worth sharing:

This is one of the first gene therapy studies I've seen that didn't end with "but we accidentally gave our subjects aggressive leukemias, whoops".

Extending telomeres is interesting! And there's a lot of good data that critically short telomeres can lead to and cause cellular senescence and death. But telomeres are just end-caps of entire chromosomes worth of DNA. They are interesting with regards to aging partly just because they are measurable and quantifiable, but aging is so much more complicated and multifactorial than just telomere length, that manipulating telomere length and saying this solves aging is an overstatement. Cancers can express telomerase and immortalize themselves just fine, for example.

Manipulating telomeres to investigate aging reminds me of this classic joke.

A cop pulls up late at night to a biologist slowly walking a spiral around a streetlight, staring at the ground intently.

"Uh, sir," says the cop, "what are you doing?"

"Looking for my keys," replies the biologist. "I dropped them somewhere on this street.

"I see," says the cop. "But why are you just looking around this light?"

"Light's better here", he replies.

You should read the last book of Maria Blasco [0], arguably the best (or at least in the top 3 researchers in the telomeres/telomerase field), and main author of the science that has inspired BioViva's work. The book is titled: "Morir joven, a los 140" (english: "Dying young, at 140") [1]

I'm going to take the time to paste here a brief excerpt translated into english:

"Is aging mandatory? Until recently, serious science did not deal with that question. After all, having ailments is normal over the years. However, what is normal today, may not be tomorrow. Mankind has grown accumulating victories against natural and normal phenomena, like high infant mortality. Fact is that more and more scientists say that not only aging can be combated, but we also must: prolonging youth could be the way to prevent cancer, Alzheimer's, and age diseases as a whole."

> Aging isn't something you can simply disrupt with a silicon valley mindset.

Usually I listen to people like Maria, who's been at it for 30+ years (not to random people in the internets with marketing and sales background). It's inspiring reading works of scientists and people so open minded, which is IMHO the essence of Silicon Valley.

> I've met organic chemists who have spent upwards of 30 years developing drugs and haven't put a single drug on the market.

Maybe because it costs a minimum of 1 billion and 10+ years of approval (plus the consent of the gatekeepers)?

1) Hetch Hetchy brings water to San Francisco from 167 miles away.

2) The Colorado River supplies 90% of Las Vegas's water and brings it from up to a 1,000 miles away.

3) Per person water use in SF for residential customers is 45.7 gallons.

4) Per person water use in Las Vegas for residential customers is 74 gallons.

So. No, Las Vegas isn't even close to being better at water use than the Bay Area.
