I remember following a tutorial along the lines of:

https://www.howtogeek.com/56538/how-to-remotely-control-your...

A couple of years back, and being absolutely horrified at the remote management available on my second-hand lenovo t420s - including management over wlan.

Sure the features are gated by price/cpu "brand" - but I think it's safe to assume a) this is complex software and will have bugs with security implications b) once it's well enough understood - it seems likely it can be "upgraded" (similar to how you today can eg: replace the bios with coreboot).

The conclusion is that we need new platforms - perhaps power5 will help.
Didn’t they desperately try to get acquired when things looked dire?
> "Yeah, but then most people just don't care."

Well, there ya go! :)

People don't care about where they spend their money. They don't care about their own people health. But the problem is Amazon, the ACA, etc.

If most people don't want to be held responsible for their own decisions, with what logic do they argue holding someone else responsible.

To be clear, there certainly are things gov / legislation can do. But that doesn't give individuals a free pass on their civic duties.
A particular advantage to intuition comes with the famous e=mc^2. Since c is 1, and 1^2 is 1, e=m.

That is clever, but you've already adjusted the mass to take into account the fact that you are now setting c=1. This reminds me of computer programming where, for the sake of an easy-to-read clarity, I decide to take one line of code and make it two. Basically, instead of doing this:

e=mc^2

You have decided to make it two lines of code:

m=mc^2

e=m

I often do that, especially if I'm working with junior devs and I want the code to be as easy as possible for them to read (90% of the time).

It's clever, but everyone should remember the assumption that allows this: the mass has already been adjusted to reflect the reality that of c=1.

This is beautiful. Thanks so much for creating it. I’m hoping you can explain what looks like an anomaly though. Looking at Macritchie Reservoir in Singapore, there’s the expected hot outline on parts of its shore, but also a dead-straight oblong running roughly east-West for over 1km. Thing is, it can’t be a running track as it’s in the middle of the reservoir itself. Any thoughts on how this artefact got there?

Stop being cultural vampires: create your own experiences instead of trying to live off ours.

Ed:

The above is probably more snarky than necessary, but in a real sense, the constant reinvention of culture due to its ephemeral nature is what keeps us memetically vibrant. The calcification of culture through constantly reinterpreting high fidelity images isn't good for us developmentally.
They ought to say "prolific inventors" rather than "star scientists." Science is only tangentially related to invention.

Also, a lot of star inventors deliberately choose not to patent their work. Focusing on patents ignores people like Tim Berners-Lee whose work would have pretty much been worthless if he had patented it.
> Antimatter is the most energy dense material in the universe.

> Our core innovation is the ability to generate intense beams of cold positrons using proprietary array moderators combined with compact radioisotope sources of positrons.

If the "fuel tank" is full of positrons or antimatter, then it's true that it "is the most energy dense material in the universe".

But IIUC their "fuel tank" has only some radioactive isotope. So the total weight is the weight of the whole atoms that is 1000x or 10000x or 100000x bigger than the weight of the positron, so the weight efficiency is not real (or at least misleading).

If they build this, it will be a nuclear rocket, that has something similar to a nuclear reactor to produce energy. Not an antimatter rocket. It can theoretically be more efficient than a usual chemical rocket, but I'll wait to see the details of the design...

Also from one of the links: https://medium.com/dissected-by-propel-x/positron-dynamics-p...

> [...]  diverting, or directing, the trapped energy from the annihilation process to propel the rocket. To achieve this, Weed, CEO of Positron Dynamics, and his team use fusion reactions to transfer the kinetic energy of the gamma-ray producing positron beam into charged particles. [...]

I still can't image how they can use fusion reactions here, or a sensible explanation of a real process that can be misinterpreted and "translated" in the press article to "fusion". This is beyond the bullshit threshold.

We actively work to make our writing hard to understand in this field. I do this all the time myself. I don't really need this complex looking equation to make my point. But if I don't have it in there a reviewer will think my writing is not academic enough. So there you have it. Once you go in realizing this is the case everywhere, it becomes a lot easier to understand academic papers.

I used this approach in college since I was not a coffee drinker. If I needed to study all night, or even for a few hours after a long day, I would work out either with some interval cardio or some light weight lifting.

It would easily wake me up and keep me going for at least 2-3 hours and I was able to focus rather easily and there was no crash from caffeine or energy drinks that are so popular now.

As for this list. Yes, nice. Thank you. But all in all small potatoes, if not terribly obvious.

Yes. They count. But these are light-weight things compared to climate change, globalization, and such. That's why the military reference matters. It's the one big budget thing Uncle Sam does well.
I always had the same feeling. I'm not bad at math in general (I'm not well versed in high level maths either), but as a developer, trying to jump in the ML field seems really impossible. One would think that he could teach himself ML algorithms, but you ALWAYS end up reading math notation instead of pseudo code.

To be honest the 3blue1brown videos seems really wonderful at explaining what is going on without going too deep, as the math in ML lecture seems to be trying to prove everything, and is always trying to teach using math notation all the time.

I guess this is happening because most of ML is mostly coming from research since it's all new, so it's being taught mostly by people who can grok the math, meaning mathematicians, it's not taught by people who are programmers. This really shows how much math should keep being math, and not leak into fields where practice matters more. Programming languages and pseudo code are not for nothing. Computers don't talk math.

So as years go by, ML will be taught more as a practice subject rather than a theory one, and things will get better. I think it's just a matter of how it's being taught, because reading code will always make more sense than reading high level math. Videos and oral explanations also help a lot.

> Once you have blocks on the chain greater than 1mb, those blocks must be valid forever. That means protocol must support new blocksize forever.

You could have the consensus rules take the block height into consideration, so blocks after a certain # must be under X MB, but previous blocks can be up to Y MB.
How does one expect to do ‘AI research’ without much of a background in math? Machine learning is pretty much all math.

Researchers are generally expected to be experts in their field. The people writing the papers on arxiv likely spent most of their lives learning about machine learning and mathematics.

Unfortunately, there’s not an easy path to become an expert. One just has to dig in and learn from the ground up.

Edit: The good news is that it’s never been as easy to learn math than it is now. When I was an undergrad in math, there were almost no resources available to learn the intuitions behind the math. One just has to keep doing proofs and exercises over and hope that it would ‘click’ at some point. But, sometimes that wouldn’t happen until many years later. Nowadays, one can watch YouTube videos where experts describe the intuition behind the math. It’s awesome.
That's "without prerequisites" nowadays? Interesting. In my world, this requires installing one of the most complex pieces of software in existence (a web browser, plus its dependencies), on top of a graphical OS (also a highly complex network of interdependencies).
I had an idea similar to this a while back.

Local shops would be provided with point of sale devices and stock control software. Their stock data would be fed into their own store websites/profiles and a wider marketplace.

Users could either purchase from an individual store or the marketplace. If they did the latter the system would find products from stores closest to their location. Users could arrange in-store pickup or same day delivery using spare capacity from nearby takeaway drivers.

Money made from sales would be nominal, but the real value would be providing data to suppliers.

Scam or joke? I can’t tell.

Seriously, they seem to be more or less claiming to take the basics of a PET scanner, magically cross that with a nuclear reactor, which will somehow produce fusion at some point, and turn that into a drive!

It's definitely bullshit, but is it a joke? It feels a bit like a send-up of those endless ICO whitepaper+splash page combos. Or wait... is it going to be an ICO?
Mass and energy are not the same property at all. E=mc^2 is only applicable at the limit of zero speed.
I remember doing it on my Vic-20, and I had done ASCII graphics on my Commodore PET in 1978! I had a thermal printer for my Vic-20 the width of receipt paper. I wrote a program from an astronomy calculation book to show where the 4 major moons of Jupiter were on an almost line due to their orbital planes being parallel to our line of sight here on Earth.

Mandatory logging is a necessary element of the CT design. What we have today is basically like the trial demo of the game. Full CT requires the completion of "gossip protocols", log auditor third parties which detect inconsistencies and a bunch of other stuff that exists today only in the laboratory, you haven't seen the half of it.

The option left open by the Chrome team was what's called redaction. The logged document would be partly redacted by for example removing host names.

It's not impossible that redaction will happen and end up being accepted, but its biggest proponent was Symantec, who are exiting the business after destroying trust by not exercising proper oversight on their relationship with Korea's CrossCert. And frankly the redaction proposed was getting ludicrous anyway. The trouble is that people who most want this, as with Brass Plate companies, aren't just looking to avoid excess publicity. What they want is to act entirely with impunity. And that's exactly what CT is there to prevent.
And I'm trying to point out that those issues are largely irrelevant in the context of how the world actually works.

You can never completely eliminate risk, only reduce it, and that reduction has costs associated with it (whether you choose to consider costs only as internal to an organization or in a broader context doesn't matter), and many times, the cost of reducing the risk outweighs any gains. It annoys me that people see "security" as a thing worth doing for its own sake. It isn't. Like almost everything else in life, it is a matter of balance.

Besides, the cost of risk isn't going up. Big breaches lately off the top of my head: Sony PSN (several times), Equifax, Target, and several hospitals and schools. To my knowledge, nearly all organizations breached are still in business and often not significantly less profitable than they were before. By the internal cost metric of the organization, then, the cost was minimal. But even considering the larger ramifications on a societal scale, what has really been affected? There's been a lot of talk, and I'm sure there's been some identity theft, but the economy remains largely unaffected and so do our daily lives.

http://lmgtfy.com/?q=single-photon+sensitivity+in+human+visi...

"Hendrik Lorentz (of special relativity and Zeeman effect fame) is said to have calculated the number of photons in
a flash of light that was considered at the time to be “just visible,” and found that the number was about
100 [2]. A significant fraction of photons was known to be lost in transmission through the eye, and the remaining photons would be spread over an area containing hundreds of rod cells, so it seemed likely that the individual rod cells were able to detect single photons. Perhaps the absorption of a single photon was even enough to cause the perception of light." [1]

"Physiologists had already undertaken rough estimates of the faintest flash that could be reliably seen; Lorentz converted their units into energy per flash, then divided by Einstein’s result for the energy of one photon, and came up with the result that roughly 25-150 photons entering the human eye was enough to perceive a flash" [3]

"[In a] landmark experiment by Hecht, Shlaer, and Pirenne (1942), which set out to determine the minimum number of photons (quanta) required for someone to perceive a flash of light. From their findings, Hecht et al. conclude that, under certain precise conditions, the average person only needs to detect around ten quanta for their visual system to detect the flash." [4]

Consider the more mundane example of heat and work. The standard unit of heat is the calorie, which is the heat needed to increase the temperature of one gram of water by one degree celsius under standard conditions. The standard unit of work is the joule, which is the work needed to exert a force of one newton over a distance of one meter.

James Joule discovered that heat and work can be related by:

h = kw

Where k is a constant equal to 4.184 calories/joule.

But really, this isn't a relationship between heat and work. This is a statement of equivalence. The constant of 4.184cal/J just tells you how the two units differ. They both describe the same property. Really, h = w. The version with k is only needed if you insist on using the traditional, different units on the left and right sides.

The same is true of e = mc^2. This does not tell you how two different fundamental properties are related, it merely tells you how two units, traditionally considered separate, actually measure the same underlying property. Really, e = m. The c^2 is only needed if you insist on using J on one side and kg on the other.

That is to say, you absolutely can have a kilogram of energy. If you have an object with a mass of one kilogram, you do have a kilogram of energy. Physicists and engineers don't typically use that unit for energy, but there's no reason they couldn't, and likewise no reason they couldn't use joules for mass.
A little off-topic, but hope this would be an another reminder that despite having huge success/hype these days, deep learning/machine learning are just another tools for solving problems, and you can't go really far if you just treat it like a magic framework (i.e. import tensorflow as tf) and fail to understand its underlying principles.

I had no concept of computer programming growing up. It was playing around with my TI-84 around junior year of high school that exposed me to it. I saw the PROGRAM button so I looked in the calculator manual and started writing TI-BASIC. I told my precalc teacher about it and she looked at me funny. She had no idea you could write programs on graphing calculators. I will always appreciate my TI-84.
Generally Rails is more powerful than Django though they have a similar set of features. If you are making a webapp I would go with Rails or Rails API. If you are making a website with some webapp functionality I would go with Django and Wagtail CMS. The free CMSes available for Rails aren't great. One feature that Django is missing is asset fingerprinting. In Rails the filename of the static asset changes when the content changes, which helps deal with caching.
Rods can respond to individual photons, that is pretty much accepted. The issue is what can we perceive. The first nerve synapse screens out about 50% of isolated photons (ones that are not correlated from other rods) which has been estimated from modeling. Which means that some of those singular photons are getting through (perceived) and can be isolated from the background noise through careful experiments.

I don't think we evolved to see single photons, but that we evolved to be very sensitive to light while reducing the noise and that sweet spot means that we can quite possibly, under ideal conditions, see individual photons slightly more than we think we see non-existent photons.

I'm hoping for RISC-V to come through, because it has a chance to commodify even further than OpenPOWER could (due to exercising somewhat less control at the point of control for the trademark, and having a design which will suit more levels of designers, possibly allowing designers to enter new markets more readily). That said, the current POWER designs perform very well, so they might be a good interim solution for me.

One problem is that the proposed offchain solutions are centralized.

Also, it's misleading to say that large blocks make bitcoin centralized. Even with large blocks, there will still be enough players that the ledger is still protected through proof of work. In any case the hashing power remains centralized regardless of block size.

You are misunderstanding the meaning of the word "decentralized" when it comes to blockchains. It doesn't mean "available to be run by the masses". It refers to the solving of the Byzantine General problem through proof of work to prevent tampering and double spend, which would still function fine even if only a few thousand nodes existed around the world.
