Makes me wonder if you could achieve a similar effect by spraying some residue over the keypad before the victim uses it, then looking at it after PIN entry. For example, a fluorescing dust. As well a special fingerprinting powders (e.g. https://optimumtechnology.com.au/latent-fingerprint-powders/) you can get stuff from art supplies stores: https://www.glowpaint.com.au/blue-uv-black-light-powder/ .

There is also thermochromic ink, e.g. a grey ink that changes to colourless at 15C. http://www.smarol.com/Ultraviolet-Fluorescent-Powder.html

At this point, I don't think it is viable to pretend that long lifetime secrets, like your bank PIN, are safe if entered into hundreds of different keypads in insecure settings.
Very cool!

I'm interested in the "hardest" 6x6 puzzle. You show the one that takes the most moves to complete, but I don't think that's necessarily very difficult, if they're all pretty straightforward. Rather, I think the hardest puzzle is one where you have a lot of options to choose from. IOW, a very broad tree, rather than a very deep one. Are you able to quantify the hardest puzzle along those lines somehow?

Which is exactly the case of djb's work here.

> In this case, the material has been placed in the PD by the original author and so no one in the world can possibly have any legal claim on it.

Wrong. djb and any possible heir of his does, because you can't place things in the public domain in mainland europe.

> But if this really concerns you, I would be happy to provide you -- or anyone else -- with a licensed copy of any of DJB's code for a modest processing fee.

Unless djb specifically gave you license to do so, your "licensed copy" is worth exactly as much as the original public domain dedication is. As far as european law is concerned, you have no rights to the work, and thus certainly don't have the rights to relicense it.

The old joke about searching something and ending up on a list seems disturbingly real.

What the hell Facebook. I get their reasoning:

>Facebook said the label was intended to only identify historical treason. “Treason was included as a category, given its historical significance. Given it’s an illegal activity, we’ve removed it as an interest category,” a spokesperson said.

But wtf are you thinking?
I use the desktop apps Quiver and Highland 2 regularly, but both produce files that are just fancy wrappers around what's ultimately accessible file formats if the companies die (macOS package folders with .md or .json contents and image files alongside).
It's really not that simple. The 'rich' in this case are the owners of the most tokens on a given list. Those 'rich' are only rich insofar as those tokens have value. Those tokens have value only insofar as people want to be on that list. Which means, that the people with lots of tokens are incentivized to maintain a good quality list.
Just today, I used xargs instead of spending a lot of time building a batching script in Python.
I wanted to launch a bunch of processes in a queue but only execute 10 of them in parallel at any time.

Here is a skeleton of what I came up with.

find $(pwd) -mindepth 1 -maxdepth 1 -type d -name ".zfs" -prune -o -type d -print0|xargs -0 -P 2 -I {} echo {}

where,

$(pwd) indicates the starting point of the listing of directories

-mindepth 1 makes sure current directory is not listed once again.

-maxdepth 1 makes sure the list does not get recursive

-type d -name - only directories and list names

".zfs" -prune - makes it ignore .zfs (snapshot directories)

-print0 - makes sure to print results without newlines. just -print will print one result per line

xargs -0 will take care of processing out spaces or newlines in the input stream

-P 2 — run two processes at once in parallel

-I {} says that replace {} in teh subsequent command from stdin piped into xargs
echo {} will be echo dir1 and then echo dir2 etc

That's just an example to show that we can do a lot with standard Unix tools before bringing in the external sophistication for data related tasks.
This could be used as an ETL process; one task is to fetch the data, another task to clean and do quality control, and then branching tasks to put the data in its final destination.

Really any task that can be broken into concrete and independent steps could be made into a pipeline for scaling and reliability.

Cute anecdote:

I'm positively blown away by the grapes we planted last year. We had accidentally left a hole in our bird netting and a deer got in and stripped both vines bare, as well as breaking many of the core tendrils. Swore they were going to die; within a month they had doubled their previous size, put out an entirely new and more vigorous crop of leaves, and then proceeded to produce two entire bunches of Riesling. (on year ~1.5 after planting).

As someone who kills most everything I put in the ground, so much love for the robustness of grapes; they probably put out at least a few inches of vine a day even at this point.
One simple idea I had was NumMoves * log(ClusterSize) as a difficulty metric. But I'm not sure. I had my wife play several different puzzles to try to gauge difficulty based on that but it didn't seem so clear cut.

No more than the true-price of Nuclear is the price to spin-up and spin-down nuclear as the electric grid demands.

There's "baseload power" (coal, nuclear, wind, solar is really good for this), and there's "Peaker power" (natural gas and hydro are really good for this).

Hydro is super-simple. Just block the water if you don't need energy, and unblock it when you need energy. Ditto with Natural Gas, which can spin up / spin down arbitrarily.

Solar, Nuclear, and Wind generate power on their own schedule and can't really be bothered. But you use OTHER forms of energy when the sun stops shining.

Natural gas is expensive to run 100% of the time. But if you can run Natural gas only 20% of the time, then you're still saving money.

According to Wikipedia, it varies. Some organizations don't require the jumper to pack their own parachute.

You've misunderstood the way to publish the data:

"These keys are X" (for each type of metadata flag).

If a given user keeps their metadata keys operationally separate from their full ID, and also updates them at random intervals, then it would be possible to have unique 'cards' (of sorts) for each given type of check.

The locality specific checks imply outer levels, obviously, but different keys might still be desired and it would be best practice for all to keep different keys to make it harder to de-identify by virtue of being one of the paranoid users.
Taking them to court is a lot different than making a complaint to a regulatory agency whose entire job is enforcement.

> any normal person with any financial savvy knows that market returns are much better than deposit returns

And, if I understand the arguments, that's confirmed by Piketty's r (return on capital) > g (economic growth rate). My concern is that more money is getting tied up in chasing financial assets than in the real economy (houses, hamburgers, cows, etc.) If you have financial assets, that's good. If you don't, that's bad. Most people don't have financial assets. Sooner or later something's going to correct that trend. It'd be better to find a non-violent solution.

The story is that you can speak and publish information even if the state does not like it. That should be the case anyway, but guns are one of those subjects where logic gets thrown out of the window and replaced by emotions - like "how you can allow people to publish information about fire boomsticks! Think about the children that are going to die, you monster!!!" So, the story is the sanity has, after long and hard struggle, prevailed this time.

As for Pandora's box, of course anything that is about guns is scary, especially anything new. So, Pandora's box.

Cloudy days are usually cooler, and you still generate solar power on those days.

True, you still need an alternative source of energy in those cases. But realistically, cloudy days reduces the sun, which usually leads to lower temperatures.

---------------

Personally, I think that cold-energy storage (aka: run air-conditioners on overdrive to chill water. Then use chilled-water to cool your house) is the ideal.

https://www.ice-energy.com/

It turns out that a vat of 480 Gallons of cold-water has a lot of cooling potential. Chill the water to 40F and you can cool down homes for hours using fans alone. With proper compressors and such, you are like 95%+ efficient.

Your failure mechanism is the probability that your vat of water begins to leak its cold air. Certainly a problem, but way simpler and less of a problem than explosive Li-Ion batteries.

If they created a national ID card that was mandatory for all citizens to have at all times I would agree with your sentiment but without one an ID is often seen as a cost for voting. When you live in poverty it's very easy to simply decide not to vote, especially when you already have to travel take time off work. It seems like a lot of us on HN haven't experience or don't understand what it's like to be so poor that you don't need an ID and don't have a bank account.

You're also comparing European nation-states to the United States which isn't fair in this case. US states have a great deal of autonomy and latitude. Since they issue their own IDs they can, and do, have their own requirements. First make a mandatory national ID a thing then you can complain about unreasonable people.
> If that doesn't accept that form of public domain the author (rights owner) could sue me and it were upon the judge, who sensible they are. (This is mostly theoretical - if the author decides to put it in public domain per U.S. law they most likely don't want to restrict to U.S.)

Generally speaking, the risk is less the author themselves (though they could always do an about-face for whatever reason, it's hardly unprecedented[0]) and more eventual heirs of them who could always decide to cash in.

In many ways, a system where the wealthy control information is what we have today. You can influence elections with donations.

Today, if a publication or data source posts information about you or your business, there is no means to correct this data. You can post about it on Twitter or email the service, and wait for a response. You can't just fix this information. With DIRT, we create a way for people to at least be part of the curation process.

Different types of data require different governance models. Some datasets are not as critical to protect and could have a low token stake. For other pieces of information, you want every writer to have more skin in the game and thus have a high stake for writing. Our bet with building a protocol is to test what incentives will curate the best data.

Direct air capture of CO2 is getting pretty good. Carbon Engineering [1] was in the news recently for demonstrating an efficient scheme at commercial scale. When I looked at the math, their technique would add about 8 cents/kWh to the price of fossil power assuming it was used to capture all the CO2. So if solar is coming in around 2 cents/kWh, you could have 10 cent electricity (competitive in many markets) that also captures as much CO2 as the average fossil unit currently creates. The progress is pretty heartening.
Unfortunately not the case, solar output peaks in the afternoon and load peaks in the evening. It's been termed the duck curve. https://en.wikipedia.org/wiki/Duck_curve
