I am a Chinese, I must claim I don't know why this paper can be published in Science because its method is totally wrong. I think most of the Chinese citizens even don't have email addresses and they just use phone call and Wechat. There are 8 people in my family but just I have sent emails before. They even never ever sent an email before and they don't know how to use it! I know how the Western media has smeared China, but I did not know that the academic has begun. It really makes me sad. If authors go back to the place they put the wallets, they are likely to find that the wallet has been taken care of or in the lost and found box. By the way, welcome to China, I know there will be some places not good but it's better to know China with your eyes and thoughts.

Ask HN: Intro to Programming Resources for Beginners
My wife is planning to do a bootcamp programming course. She's currently taking some prep course offered by the company and is progressing along doing various problems on a daily basis. This course is mostly independent studies where the instructor assigns problems with some lectures but you're expected to figure it most of it out on your own. You can ask questions and request help via a ticketing system but it's a little bulky to walk through. As I look through some of her solutions, I noticed she's a little deficient on some fundamentals (eg scoping, by value/reference concepts, etc.). They're learning programming using Javascript.

Obviously I can help her but I work during the day and she's taking some time off to focus exclusively on this pivot so I don't want her to sit around waiting on me.

Does anyone have any good resources (authors/books, bloggers, youtube instructors) that they like that has an easy to understand teaching style for beginners?

TIA
I was thinking the same thing. I don’t think anyone was trying to deceive anyone.
Buy one of those and try flexing it. I have held similar products in my hands. It's still built from individual 125mm sized monocrystalline si cells. It's a little bit flexible, but not like you think, and certainly not going to curve to fix a multidimensional curve of a car body panel. It's not flexible like a vinyl car wrap, or even the material of a zodiac boat, it's flexible in the same way that a 1cm thick foam insulation board is flexible.

It's also ridiculously expensive compared to the $0.48/watt STC cost of big 72-cell panels by the pallet load.
Besides the amazing project, the presentation page blew me away - the sticky text on the side, the progressive loading of images, the tasteful white of the background, the subtle coloring - all of it shows a lot of care and attention, I love it!
You're right. On the other hand, I respect the efforts of those who try to make a difference (for example by taking the effort to replicate prominent studies in psychology).

Sociology and economics are different beasts altogether. By definition, you can't conduct any meaningul controlled study, so using the name of "science" is a bit of a stretch. Nevertheless, you can't deny that certain "laws", however fuzzy they be, do exist in these fields, and studying them can be very useful, no matter if we call these science or not.
Not even close. I've seen figures in the order of 10^1000 years for the Heat Death.
Given that the sun will die in about 5B Years, this is a bit of a gimmick :-D
QUT did a study (the CAUSEE study) that looked at the predictive factors for startups to succeed.

One of the best predictors for failure for Australian startups was if they had accessed a government service to help startups succeed. Of course, that might be selection bias.

The only exception to this (and actually was a predictor of success) was accessing the R&D tax concession.
Sounds familiar. Never really worked for in school, work is different so. There I usually fill one college block every two months or so. Not that I ever read the notes again. But it kind of seems to get harder with age. Especially the "once written not forgotten" part...
The Pi Zero W can act as both a USB host and a USB HID device, i.e. can act as a keyboard/mouse. This makes it a very capable bad USB/rubber ducky/automation tool with Wifi enabled.

I've created a small repo to demonstrate this. Connect a zeroW to a computer, the Pi will expose a hidden Wifi network that by connecting to it you'll be able to send remote keyboard commands (or execute ducky scripts) on the host computer:

I remember chatting to someone working on the project at the University of Southampton years ago .. I think it was back in 2004. Great to hear it's come to fruition.

The length of time this type of project takes amazes me.
This is really one instance of a much larger problem in the "soft" sciences, where results that don't replicate are commonplace, and 'null' results that don't appear to give "decisive" evidence for some effect are filed away and go unpublished. It's a mistake to focus on "gender bias" alone, it's a funny example but not really what's going on.
During my MBA one of our lecturers was a tax lawyer, and the stories he told of the ATO utterly shafting people were horrendous. I might be biased because of this ;)

No, it most certainly does not. Stop with this nonsense.

This makes this software ineligible to be called "open source" as per OSI definition. That's it.

The world is not binary. Not everything that 100% free and open is proprietary. If it's not an OSI-approved license, but the source is open and avaialble for tinkering, changing and redistribution, even if conditionally, the altruistic spirit is still there and it's still an approach that is welcoming of a typical O/S use.

However this also allows authors to reserve rights for commercializing their work later on and it's an absolutely fair arrangement. No reason to denigrate their work because of that.
Not that small. But say smartphone case sized solar panel.
This whole thread and only one mention of org-mode, what is the world coming to.
Strong words and big generalisations, but let's assume you know what you're talking about.

Take the social science I studied, linguistics. How does it lack falsifiability? Theories of how languages evolved can be disproven by contradictory evidence in the same way theories would be in any scientific discipline. For example, we know English and German ultimately have a common ancestor, because we can see the similarities between their modern and older forms and explain them in terms of consistent sound changes, and we can systematically explain the differences between the older forms of the two languages such that we can reconstruct what we think is their precursor, and then show in the same fashion that they are related to other European languages. Now, if you believe English and German are in fact descended from ancient Chinese, you can falsify the current theory by showing how they could have evolved, but you can't, because any similarities are superficial and can't be explained systematically.

Or did you mean only social sciences that you don't like? Which ones?
It is much easier to pretend to do science than actually do science. When the system rewards imitation science as highly as real science then you can expect that you will get a lot of lookalike science.

Why work hard collecting data from 1000 people and finding nothing exciting, when collecting data from 50 is accceptable with the added kicker that chance alone might throw up something supporting the politics of your peers.
Does anyone know a resource which explains the theoretical limit for retrievable, durable, information storage?

I would assume the most dense medium possible would be a collection of neutrons, since neutron stars are the most dense object other than a black hole, but retrieving information from them doesn’t seem feasible.
Thank you for this comment because it puts one of the solar cars (at least the Sono Sion) in context--10 km range per day. It's a great option if that that work for you!
Since it's trendy to recommend related books on HN, I'd nominate "Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science" by none other than Alan Sokal. It's a fascinating read and just as valid today as it was 20 years ago when it was published, which is actually a bit depressing in my opinion.

What are the concerns around RPKI?

I'd like to know why some companies aren't implementing it if it solves similar problems. What kind of criticism does it receive?
I was just wondering about that. But light emissions would probably cancel solar intake.
Is that unique for China though? Large enterprises in the US and europe are also starting to ditch Oracle for other alternatives.
Is Medium for pay now? They told me to sign up to get "one more free story".
I would always take notes on paper as others have said as I think it helps with retention, at least for me.

Even then I would only take notes of equations to memorise them and things that the lecturers said that were even not explained properly or absent in the handouts/slides. At my university there were recordings of the lectures but I was too lazy/didn't want to waste my time looking up exactly what they said.

I have it set up to run a project where a subreddit has control over the watering of a live plant in my apartment.
The pi runs a reddit bot that reads the votes, and can switch on a pump to water. It also collects data about sunlight, moisture, temp and humidity to help inform the decision about watering. Despite many people's preconceptions about the goodness of the internet, I must admit that they do a wonderful job caring for my plant!

Facebook Graph’s Not Dead
Assume that the price of an item is $100 today ($200 original price - so a 50% discount). A week from now is Black Friday. The retailer has said 70% off on all goods. Now if the retailer increases the price to $333.33 (100/(1-0.7)) and then discounts it by 70% to give a final selling price of $100, wouldn't you feel cheated? I know I would.
The problem tends to be user interfaces built for one purpose and used for another, whether it's originally by law enforcement (due to search warrants) or by support.

With something like Google Drive or Dropbox, that's where I'd look.

You can say these things shouldn't exist, but then you have no support. How do you help grandpa when he has trouble with his account if you can't do anything?

The end-to-end encrypted, no-support you're-on-your-own future isn't well distributed yet, and as long as there are people who can barely use a computer without a lot of hand-holding, it probably never will be. Someone has to be helping the users. They must trust someone. Such trust can be abused.
I can subscribe to this. Whenever I needed to learn or revise something, I would just write it down again, usually paraphrasing the original material.

While I wouldn't use that material directly ever again, I noticed that I would often paraphrase a paraphrase, so to speak, because I would remember some of the material.

Tangentially, this thread shows that people prefer different ways of taking (or not taking notes) usually due to a habit itselfc as opposed to superiority of one method over the other. It reminds me of Dvorak vs qwerty, while technically superior for typing in English, the cost of switching is not worth it for most people out there.

I took a bunch of notes on my laptop, but never used any of them in studying for finals. I just used other people's outlines.
It was probably an oblique reference to https://en.wikipedia.org/wiki/Grievance_Studies_affair and more generally the idea that gender studies is actual more about taking grievances at gender bias than neutrally studying them.
Interesting side effect, this also gives us some clue about what kind of ... information storage devices we should be looking for in other heavenly bodies.

Had we found a bunch of silicate glass pebbles in Europa, we'd have considered them a curiosity. After this, we have good reason to find a way to ship it back and have another look.
>> Accidentally (?) she managed to create the best representation of AI I have seen in art: all that counts is that you call it AI even if it is a simple algorithm.

Backpropagation, which most researchers will agree is an AI algorithm, is a "simple algorithm".

So are many other AI algorithms, some of which are simple enough to be understood so well that most people don't recognise them as AI anymore: search algorithms like depth- breadth- or best-first search, game-playing algorithms like alpha-beta minimax, gradient descent/ hill climb, are the examples that readily come to mind.

I think the above article and your comment are assuming that, for an algorithm to be "AI" it must be very complicated and difficult to understand. This is common enough to have a name: "the AI effect". A few years down the line I bet people will say that "this is not AI, it's just deep learning".

There's no reason for AI algorithms to be complicated. Very simple algorithms can create enormous complexity, even infinite complexity. The state of deterministic systems with even a couple of parameters can become impossible to predict after a small number of steps if they have the chaos property. Language seems to be the application of a finite set of rules on a finite vocabulary to produce an infinite set of utterances. Complexity arises from very simple sources, in nature.
Pull it down and have a look. If it’s already broken, you’re in a good place to start.

It's not just the verbatim aspect, part of the issue actually is the distinction between laptop and paper. When you hand write notes, another piece of information you store in your mind is where on the page you wrote it, and what it looks like. Then, when you need to recall, you can often remember where it was on the page and generally what it looked like there, and that can help remember the actual content.
If you are referring to the open worm project, then the conclusions you have drawn are exactly the opposite of what I have drawn.

As I understand it open worm is a hodge podge of statistical and numerical methods to try and replicate the sensorimotor behavior of c elegans. Open worm is neither complete, accurate nor elegant, despite knowing c elegans connectome and having mapped the some 900 cells in the worms body.
Most likely the defect rate will reach a specific value so that the storage medium is no longer considered reliable.
The Wikipedia article says: "By the use of older – and thus no longer legally protected – components of traditional car manufacturers this low price compared to other electric cars is possible". Can anyone shed some light on this?
In college (early 2000's) we connected a lot of old machines (486's & Pentium I/II's) in a Beowulf cluster and got a fairly reasonable processing speed.

Creating a cluster is also a great learning opportunity.
Im always sceptical about these claims of archive longevity. IIRC when CD-Rs were first available, they were touted as suitable for century long archives. The reality was far from that.
Thank you AWS. In the meantime, if you could offer me just one basic setting that users have been asking for years (hard limit on your spending), it would be even better.
It's mostly because most startups are not scientific and most of the funding goes toward scientific ideas and companies. If you don't have good scientific credentials and scientific research to support your business hypothesis, you will have a hard time getting funded.

Sun will become a red giant in about 5 billion years. Space habitats, and habitats on moons of gas giants will still be possible.
I dunno, but it seems to me universities increasingly focus on press releases and marketing departments...

5D and 13.8 billion years? Phony. I know no sane scientist or enigneer that would say they use more than 3D physics. Sounds like catch phrases to sell. With such logic plain old HDD is at least 4D, because it uses CHS coordinates and magnetic orientation, to store data.

To me such communication style undermines the real scine behind it. Do they have nothing better to brag about than excuses to call invention 5D? Why introduce such noise?
So if one of these discs was dug up by a civilization with the level of technology we had in, say, the 70's, would they be able to tell what it was, much less make something to read it?
CPUs are more generic though and pretty much every single GPU accelerated text drawing operation i've seen allocates permanent GPU resources (textures mainly). It isn't impossible to not do that, but if you only allocate the necessary resources for the GPU on an as-needed basis and then release them once you're done, you are introducing latency which invalidates any gains you may have. The alacritty terminal linked elsewhere in this post, for example, keeps a bunch of atlases around with hundreds of glyphs which are local to each instance of the program (thus using both CPU and GPU resources) and for macOS and Windows ignoring any system-wide glyph caching the APIs it uses may already have (caches that will be created - and thus resource allocated - anyway when it tries to rasterize those glyphs for its own use).

FWIW yeah, i agree that most people do not really need 4K displays but that is another matter.

Can I rant about the 5D?

"It's been dubbed five-dimensional (5D) digital data because, in addition to the position of the data, the size and orientation are extremely important too"

Orientation is inherently important anyway. Have you ever tried reading a book upside down, and what does size bring? Other than lowering density. And obviously position is important, it's the difference between data and randomness.

I think it’s the use they get. An early one would be 20+ by now I think. Similar age grinders from Mazzer also seem to burn out their switches. This suites me fine as they then get sold as having burnt out motors, which I don’t doubt can happen, but I’m yet to see it and have bought several dead.
Repair, respray and then they usually just sit in a line for months as I like them too much.
After years of contemplating, I once tried going after an SBIR with a partner. It was for a robotic ship tank inspection system. We put a lot of time and effort (about a month of constant work) into designing a strong concept solution and puting the proposal together. However, we had a few basic questions and the government technical and programmatic POC on the solicitation was non-respinsive after several contact attempts.

We submitted our proposal, meeting all of the insanely meticulous format requirements, but as feared we never recieved a response. Instead, the award was given to an off the shelf product for an incremental upgrade. Clearly, the awardee was already identified by the PM before the SBIR solicitation was even written, so I essentially lost a month of my life by being mislead into thinking the solicitation was truly open. The SBIR was just another way to funnel R&D money to the existing product the PM manages.

Gov't PM's do this because government funding comes in "colors" that specify by law how the money can be used (e.g. Operation and Maintenance, Construction, R&D, etc.). However, for some programs it's hard to secure R&D dollars, so back channels, like working with your supplier to craft an SBIR solicitation you know you will be awarding to them, are needed to fund improvements.

I suspect the fear of this occurnace (wasted effort) is the primary reason startups avoid government funding, and I can tell you first hand it's a valid concern. If you think the U.S. doesn't have it's own backchannels of corruption and unfairness in the contracting community, and that such practices are limited to developing or non-ally nations, you are mistaken.

Ironically, I think one of the reasons this type of behavior has emerged is thanks to the push from our own citizens - largely due to the "fleecing of America's dollars" scare of the 1980's and 90's, which asked America why the government was buying a $100 hammer or a $200 toilet seat. The push for transparency and frugality has driven the government in many cases to a culture (or requirement) to use funding loopholes and side agreements to get work done and also award contracts to lowest bidders regardless of the quality of the offering.

There are good program managers out there, doing their civic duty and following all the rules to the best of there ability. However, to me, the chance of finding such honest brokers and opportunities isn't great. If you want to work with government, your best bet (IMO) is to go to a trade symposium in your specific area of interest and strike up conversations with PM's in attendance to discuss solutions to their problems.
Didn't know that, the guidelines a good idea, thanks.

High quality discs are capable of that, the problem is the drives to read them all broke down. For an ultra-long term storage medium like this that's moot. If someone wants to read one of these in a billion years, they'll just have to develop the tech, but that would be true of any such long term mass storage medium. It's not necessarily a strike against this particular implementation.
I still use a paper notebook at work to track my day to day action items. It feels so gratifying when you simply check a task as complete. I tried using a tablet for that matter, I just felt like I ignored my action items as it felt they were out of reach. I have to always look for them in the tablet, when in the paper the page is looking at me without me have to look for it.

In addition, I work in secure labs and electronics are a big NO, notebook on the other hand it simply works.
