Agora's ballot privacy (secrecy) is apparently based on Neff shuffling.

A verifiable secret shuffle and its application to e-voting [2001] https://dl.acm.org/citation.cfm?id=502000

All prior crypto-based voting systems I've studied rely on hash collisions, algorithmically simulating the secure one-way hash of physically dropping a ballot into a box, for an individual's ballot to get lost in the herd. But for this to work, ballots have to be simple and elections have to be large (enough).

In the USA, ballots are complicated and precincts are small. Appropriate for elections administration based on the Australian Ballot, bad for crypto-based balloting system.

I'm very surprised this is the first I've heard about Neff shuffling.

But I know a lot about VoteHere. Even though they are a proven bad actor in this space, I'll suspend disbelief and see if something good came out of their efforts. The Agora people appear smart, earnest. So maybe there's something here.

If Neff shuffling (or something similar) actually works for this application, it'd be remarkable. Least importantly, I'd have to update my world view. Specifically: no fully digital voting system can both protect the secret ballot and ensure a public vote count. (In practice, electronic voting systems do neither.)

--

PS- Scanning the other comments, feel compelled to point out:

Design the whole system. Understand election administration. Protecting the ballot is not enough. Information also leaks from poll books, voting history, etc., which then deanonymizes the secret ballot.

For Sierra Leone, Agora might be a great idea. Maybe the benefit of extending the franchise (reduced costs, increasing access) outweighs the loss of individual privacy.
>Nearly every culture that has ever existed has recognized that someone taking something from you by force is crime.

Yes, most cultures recognise some notion of property, few would agree with taking the clothes off someone's back. But the exact nature of these property systems is varied, and the idea that all things must necessarily have an owner, and anyone else using them is "taking them by force", is by no means universal.

Many cultures have some notion of public property, and indeed many of these public property rights were violated historically in order to establish the modern notion of private ownership.
This is one of these interesting topics where people are very likely to ask, "Have they thought of this?" And it would be great if there were a list of discarded ideas along with the reasons for why they were discarded.

For instance I specifically would like to know if large areas of IR reflective material could be used to cover strategic areas in the arctic and antarctic to build up ice barriers. Coat sensitive areas with something that stops the ice from absorbing heat and hey presto maybe you get significant gains for your investment?

If we're starting a list of possible alternatives then Tutanota is good (Germany IIRC).
Regex is great for very simple text processing, and I tend to do a lot of that.

The most important parts to get comfortable with are:

* Capture groups and alternation

* Character sets

* Anchors (start and end of line)

* Common escape sequences (digit, word, whitespace)

* Repeat (any, one or more, n-m)

* Common flags (global, multi-line, case-insensitive)

If you need more than that, it's time to start evaluating other tools IMO. A lookahead here and there is okay, but I'd avoid them if possible.

The best way I found to learn regex was to take a set of inputs that I wanted to match, (and a set that I didn't) and play around on https://regex101.com/ until I got a pattern that did what I wanted. You'll very quickly start to learn the above bulletpoints, and before long you'll be able to write patterns without any reference.

If you find that your regexes are getting too large or unwieldy or difficult to understand (despite knowing the above bulletpoints) then you probably need a parser or some other more suitable tool.

The example I gave was indeed Hebbian. I was merely using it to facilitate understanding of the general physiological mechanism used by neurons to manage their synaptic weights. The same general mechanism is also used in (mono)synaptic efficacy management for non-associative learning (e.g. sensitization, habituation, etc).

But I agree there is much we neuroscientists can learn from the machine learning research that provide insight into the biological system. Trust me- we are paying close attention.

Thanks for explaining where you're coming from.

It's a weird space. I see the general concept behind cryptocurrencies as bringing the same benefits you've outlined and from a technology and software perspective these projects are fascinating.

My contention with most of these projects and users is that in these specific implementations nearly every single one of the cryptocoin projects are designed to enable oligarchical wealth extraction from downstream investors - especially in the case of uninformed users/speculators who join the network later.

The question becomes of sustainability - if there's no underlying value to the asset and it relies on speculation and the supply is heavily centralized among a small pool of early adopters than there will likely be a point where buy pressure runs dry and most of the late adopters will be unable to exchange the same amount of wealth they traded into the system.

I've somewhat researched the topic of "durability + harddisks/SSDs" for a while since I was interested in writing a simple Key-Value store.

The simple answer is that "fsync" is basically the best option you have. The hardware controller tells the OS "sure, I've written all this" and the OS has no real mechanism to verify this.

Worse even, some cheaper SSDs an HDDs do reorder writes around fsync's, in one case a bad HDD was able to corrupt ZFS(!) (reproducible) when loosing power during a write.

The fun thing is also that filesystems themselves aren't much better either. Ext4&co. sometimes don't propagate write errors at all, so in the remote event that the HDD controllers lowers itself down the plebian OS to tell it that it may have lost a byte or gigabyte, the filesystem is probably going to ignore it since the write was already buffered and fsync'd.

The only real reason why computers aren't spontaneously combusting is that most HDDs and SSDs don't do this, even in consumer space and an unexpected loss of power is rare to also meet some critical write. (ext4's physical journaling also helps a lot to make it resistant) If you want a full taste of how it works out, get a Raspberry Pi, load in a super cheap microSD and unplug the power a couple times while running a browser or other disk-heavy load.
"Make enforcement of fines much more fast and certain, and you can solve speeding while lowering fines."

If "solve" means legitimize it, yes, you've solved it.

Google for "daycare fine study" and notice that adding a small but significant fine to a behaviour you wish to discourage increased that behaviour rather than decreasing it.
> high tariffs

https://fullfact.org/europe/uk-leaving-eu-trade/

" EU’s trade weighted average MFN tariff was 2.3% for non-agricultural products. This is an average figure and tariffs on some individual products are much higher, especially on agricultural goods. The EU tariff on cars, for example, is 10%."

Is 2.3% really worthy of being called "high"? Many of these tariffs are reciprocal anyway.

That is a popular fiction for why the speed is set lower than the design speed that someone young and fast would expect, but the real reason is to figure out how to make it so that the people who drive based on the feel of the road and the people who drive based on the speed limit have the mean of their distributions at the same place, minimizing the speed differential between people on the road (which is what is extremely dangerous).

https://priceonomics.com/is-every-speed-limit-too-low/

> Traffic engineers believe that the 85th percentile speed is the ideal speed limit because it leads to the least variability between driving speeds and therefore safer roads. When the speed limit is correctly set at the 85th percentile speed, the minority of drivers that do conscientiously follow speed limits are no longer driving much slower than the speed of traffic. The choice of the 85th percentile speed is a data-driven conclusion -- as noted Lt. Megge and speed limit resources like the Michigan State Police’s guide -- that has been established by the consistent findings of years of traffic studies.

I have a Matias Ergo Pro. It's a brilliant split keyboard. Great quiet but tactile switches, tenting, etc.

But the QC is terrible. The interconnect cable had connection issues, keys are often 'stuck' (not physically, just keeps repeating until I press it again), etc.

And the internet is full with complaints. It's a pity, but I would not recommend them right now. (I've sent it back then got a new one with exactly the same issues, then I didn't bother in the end even though I paid more than 200 Euros for it.)
Of course there are. They do it by figuring out how to get material non-public information. That's been the scam for as long as there has been a stock market, the rest is noise.

The OS can't do anything.

The Controller says "Fsync? Sure thing." and that's basically end of the story. Unless the cache is visible to the OS, the OS simply has to accept what the controller says as truth.

The issue of a controller lying is to my experience very rare and only really exists for very cheap harddrives, SSDs or SD cards (interesting for RPi).

I'm not aware of an enterprise hardware that does this, I suspect if anyone tried they'd be out of business quick.

By cheating.

The naïveté of these Wall Street comments is astonishing.
Maybe, yes, but it doesn't make property right an inherent part of nature, merely a rather popular tactic for higher-evolved animes (I don't see mold taking territories, it grows where it grows and doesn't have any intelligence to defend it or see it as it's own).
for me, the problem is the key (pressing 1 time resulting in 2 chars, not sure what's the proper term for that)

"Just do it" actually sounds like a good reason. Tackling difficult engineering problems always creates spinoffs even if the core activity is fruitless.
Paid 150 euros for mine (matias silent something), was faulty (some keys would either not record a press, or record twice), asked for a replacement.

Replacement had the same problem. 150 euros thrown.

Otherwise an awesome keyboard, that I'll never recommend to anyone.
No, this is more specific than just using a DB. If they use Postgres to handle HR then it's irrelevant. This is specific to using large quantities of potentially tainted information and then not disclosing the use of that information. Which is more or less the definition of parallel construction.

Further the problem with parallel construction is not that it hides tainted evidence it's that the courts can't decide that the evidence was tainted. Even if all the information was fine the technique inherently creates problems.
You're paying fees for something different than just buying and holding an index ETF - and that is a long-term diversification across asset classes and georgraphies, regular automatic rebalancing of portfolios, goal-based investing with multiple financial goals, reporting, etc. I am not saying that buying a single S&P ETF is bad, but you can do so mych more for your financial future with robos, that it is basically incomparable.

Edit: I also forgot an increasingly important diversification by asset manager as well.

For scale: The net exports (Chines exports less imports from the U.S.) of China to the US are less than 3% of Chinas GDP.

China will certainly notice that, but in the long run the U.S. will certainly lose more from that decision: The heavily (illegaly?) subsidized U.S. agriculture will get a hard hit, as will every industry that relies on Chinese components, from smartphones to cars. It will be a boon for the other continents, though, as their companies will gain market share, because the U.S. products will have to be sold at higher prices.

"blockchain-based election" is a bit of a stretch. A third party recorded part of the election results using a blockchain. The election itself was still a paper ballot.

Perhaps if the company had used Postgres to store the results there would have been an article called "Sierra Leone just ran the first RDBMS-based election"? Probably not, since relational DBs are not buzzword material.

You are thinking in absolutes. The politicians don't. They're fine with 99% solutions that cover the general population. The remaining 1% of dissidents will be dealt with by throwing them in jail, not by making the technology impossible to access so that they are forced to give up their efforts.

Adam Smith also said the wealth of nations depended on the economic empowerment of its populace. Policies and regulations meant to better the citizens and not the corporations add the most to the wealth of the nation.

Quote:”What improves the circumstances of the greater part can never be regarded as an inconveniency to the whole. No society can surely be flourishing and happy, of which the far greater part of the members are poor and miserable.”

And:“[The rich] consume little more than the poor, and in spite of their natural selfishness and rapacity…they divide with the poor the produce of all their improvements. They are led by an invisible hand to make nearly the same distribution of the necessaries of life, which would have been made, had the earth been divided into equal portions among all its inhabitants, and thus without intending it, without knowing it, advance the interest of the society, and afford means to the multiplication of the species.”

> every parcel of land would have some advocate who cared very deeply about the environmental quality of their land.

Commodore Business Machines for several decades had their plant in Westchester, PA, leak assorted chemical related to their chip manufacturing. When this was identified, they started some improvement work, but didn't fix the problem. The site was eventually sold to a company that bought it knowing it was contaminated, who continued to operate a chip manufacturing business there, until the demanded improvements made it impossible for them to operate.

Despite corporate ownership for years, nobody advocated or cared very deeply about the environmental quality of this land until they were forced to by the EPA, because it did not affect their business. Other people nearby would largely have remained unaffected for many years too, until chemicals started seeping out, at which point Commodore was in decline and eventually went bankrupt.

Here's one of the documents regarding this site: https://semspub.epa.gov/work/03/50245.pdf

I'm sure there are cases where the issue is that nobody has any direct legal interest in a piece of land, but a lot of serious environmental issues have explicitly happened or escalated because the owner did not care or could not afford to remedy the problems.

The bigger fiction is to think that the owner will always "care very deeply" about the environmental quality of their land.

Fraudulent payments mean things like e.g. a bank itself was hacked.

As an account holder you cannot recall a transfer. It is not possible.

In the past it was sometimes possible to cancel a transfer before it was processed by your bank (so the transfer was not booked yet), but nowadays transfers are processed essentially immediately. Some banks have never permitted this.
