In the long-term, I think blockchains will make a major showing in the design of self-driving vehicles (SDVs).

For SDVs to really take off, it needs to surpass the safety of a human driver but the only way to do this reliably in a way that avoids the high costs and ugly protrusion of roof-mounted LIDARs is for SDVs to use low-cost internal sensor inputs and fallback on low-cost external sensor outputs from nearby vehicles[§] and road infrastructure.

Essentially, what I think is missing from all SDVs currently in development today is an important ingredient behind why Internet-use is so widespread today: a common communication protocol between SDVs from different manufacturers.

Once a common protocol is adopted/legislated, all SDVs will be expected to record any accidents encountered during any trips in a partial copy of the “road blockchain”. Stated differently, details of accidents and near misses will be recorded with timestamps on the partial blockchain maintained by each SDV in a way that the exact position of all SDVs within the vicinity of a car crash can easily be reconstructed. Of course this will mean SDVs will use clocks that are network synced.

If 6 cars are in the vicinity of a crash between 2 cars, the trajectory of all cars before and after the crash could be reconstructed using the blockchain data from those 2 cars. If the 2 cars’ “black box” are lost due to them exploding on impact, the data could still be reconstructed using the partial blockchain data from the 6 SDVs proximate to the crash.

The “road blockchain” would be especially useful in accident investigations but its privacy implications would need to be properly thought out.

§: If a SDV has front sensors that start to return conflicting inputs while in operation due to inclement weather for instance, rather than the onboard computer aborting the ride in the middle of nowhere, it could switch to operating at partial instead of full situational awareness. In this state it could routinely query any three nearby vehicles for help: the vehicle in front, behind it & to its left to regain some level of situational awareness.

Another use case would be falling back on wireless beacons when Internet access over cellular is lost. The SDV could start an adhoc network over wireless where it can broadcast a request for help from nearby SDVs. Something like: “I’m traveling from LA-SF. I need a recent copy of the point cloud from anyone traveling in the opposite direction (SF-LA)”.

For this to work at scale, a common protocol that allows a SDV to start a wireless conversation with any nearby SDVs would be required.
I'd go even further - if you're doing leetcode questions instead of talking directly to VP/GMs and having them sell you on the role, you aren't high status at all.
According to the diagram of the output buffer on pdf page 15, they pull down against Vdd (the negative supply). What is left unstated is that the pulldown transistor has likely been designed with a Vt such that when "on", and pulling down against Vdd, the output goes quite close to zero volts.

Uighurs have been committing terrorist attacks since way before these camps have existed: 1992 Ürümqi bombings, the 1997 Ürümqi bus bombings, the 2010 Aksu bombing, the 2011 Hotan attack, 2011 Kashgar attacks, the 2014 Ürümqi attack and the 2014 Kunming attack. And bombing a shrine in Bangkok killing 20.

Home made bombs dropped in markets, driving trucks in to crowds of people, random knife attacks. Doesn't sound unfamiliar here in Europe. They're all reading from the same book.

What China is doing is pretty horrible but it's not like Xi woke up one day and decided he didn't like Uighurs.

Do you also genuinely believe think Hitler Adolph was gassing Jewish people out of a real concern for sneaky backstabbing, and Stalin Joseph did the same to many more nations he purged? Punch yourself in the face, get real.

> But there's bad blood and BS decisions already, so can this still happen? The Han Chinese need to overcome their distrust of non-Han for this to be a possibility.

Do you think that Xi, and Co. give any real f..k for feeling of Han Chinese? Get real. One phone call, and he can have any "rightist element" dead and burred the same day.

Now, if the sense have not come to you yet, and the motivations for Xi's actions are not yet crystal clear to you. Please, please read a very well researched topic historically "Why did Hitler commit genocide?" And there is a much more recent refresher, much more approachable, and illustrative for a Western reader "Why Rwandan genocide happened?"

Then read https://www.jstor.org/stable/41479554

Hitler's "hate" for Jews was far from some compulsive paranoia. Besides sharing some generic Austrian antisemitic tropes, in his head he was far from his self-depiction in "My struggle." He had few Jewish acquaintances, and even shielded some from his own prosecution campaign.

What he did was not something new, he simply did the same what hundreds of European politicians did over the course of two previous centuries of early (in-)civil politics: get a convenient scapegoat, get a convenient political punchbag, and punch, punch punch.

Even a kindergarten bully, when he comes to a new class will not punch somebody second, or third to him, he will pick out the easiest punchbag in the class, and use violence against him to terrorise, and get the class in line.

I don't think the parent comment suggested anything like what you just said. And I agree with that parent comment, in that I find it amusing mental-floss to imagine how a very-low income family in the US can completely avoid Chinese made products.

Ouch. Kudos for the pun, that was truly awful. :D
Chinese influence runs deeper than manufacturing. Politicians across the West (or sons of politicians) have sold themselves to various Chinese interests. No need to invade the USA when you can just buy off a vice-president's son for $5million, for example.

It won't. The Jews in Germany weren't offer even the shitty options the Uighur have. The German state never tried to assimilate the jews. Even worse - the government sent to the camps even jews so thoroughly assimilated that it was surprise to them that they were having Jewish ancestors.
> Yes, the transistor is a current sink. Since the gate is wired to Vdd, the transistor is stuck on so it provides a fixed current limited by its size.

That seems wrong? Q3 appears to be effectively acting as a diode with cathode fixed at -9V and a 5V threshold, such that Q2's gate (Q3's anode) can never be above -4V, but will be pulled lower by the capacitor if `out` drops. (At which point Q3 doesn't provide any current because its anode is down at -18V.)

The interesting cases are much more companies wanting to timestamp dozens to thousands of documents or events per day. But there the "notary" solution is a common one - many companies offer timestamping as a service with an API, and in most cases you can probably find one all involved parties can trust (e.g. some CAs run such services)

>In fairness, protestantism was a rejection of the idea that the Catholic church has a monopoly on Christianity.

Well, there was already the Orthodox church, the Coptic search, and a few others, so that was quite clear.

Protestantism was both a reaction against the power of the Pope (via Catholic church) to the Germanic etc nations, who remained "christian" but wanted their own church to break away from Rome, plus a simplification of the faith that reduced its subtler points to fit their mentality...

A version of christianity for peoples who haven't had much of a philosophic legacy. Then you add calvisnism for people who'd like to get richn and feel good about it, without all the christian guilt about the subject of money (they kept and expanded the guilt at the domains of sex and fun -- which is why protestants have been way more killjoys than the catholics).

Not really. When you get away from the Free Software hippies (i say that endaringly as one of them) who want freedom from copyright, the way religious people want purity, copyright is largely about risk management.

> Twitch isn't any different than the screenshot case...

There's lots of differences (in both directions). Lots of twitch has explicit permission to use the video games, most of twitch isn't streaming abandonware, the argument for fair use is probably present for both but much easier to make for wikipedia, etc. In terms of wikipedia, the concern is ideological purity, not that some defunct video game heir is going to come out of nowhere and sue us.

> it took art to load the DOSBox programs...

It took skill, not art. The screenshots themselves don't contain originality by the author of the post, so he doesn't get copyright of it in usa (european countries are often different). See https://en.wikipedia.org/wiki/Bridgeman_Art_Library_v._Corel.... I'm not sure how that relates to your point though. Even if the screenshots contained originality from the author, like how twitch streams do, it doesn't remove the copyright from the original video game designer, it would just mean both have a copyright and you would need permission from both to do stuff with the created work.

> defining guidelines for interpretation of pathological finds and they state explicitly that it is better to "overdiagnose"

Was it definitely after pathology reporting? It's normal to have a low threshold to send people to biopsy. From the number of developed cases you can get some idea about what ratio of "ok" results you should have as a referring doctor. (this is tracked) But once you do biopsy / further checks I haven't heard of overdiagnosis by a large factor - not the "you should have surgery" overdiagnosis anyway. "Wait, see how it develops, retest" seems more common.

There are fair use rights that are not able to be satisfied without a copy.

You can assert all of that, but unless you have some landmark precedent to cite that agrees with what you're arguing, I'd like to hear a court decide on that. Sony Betamax says what I'm arguing, and archival can be for fair use, too. There is 36 Cinema, which maintains copies of classic kung-fu movies that aren't available for purchase anymore, and invites Rza from Wu-Tang Clan on periodically for broadcast viewing with a value-add, Rza's commentary. Since the movies are no longer available for sale, there is no impact to marketability. Since commentary is added, transformative. That's all fair use, format-shifting. I say youtube-dl is a tool for format shifting, with substantial non-infringing uses that present a compelling value and don't impact marketability, exactly in line with the Betamax case. If format-shifting and copy for archival was strictly prohibited as you suggest, those movies could be lost forever whenever a format becomes obsolete. When was the last time you saw a VCR? (CD or DVD player?)

That's just one of the things that the fair-use rules and exemptions in copyright were written to help resolve positively.

You can record anything on TV with a VCR, even if it's available separately for purchase on video. There is no technical way I can see in which this scenario differs. You are not obligated to pay for content again and again in every medium, format-shifting is also an allowable kind of fair use. Everything you're saying makes sense, but I don't think it's as clearcut as you say, until it has been decided by a court (and appealed, and decided again by a higher court.)
What are these companies timestamping though? That's what I meant to ask. I know there is a need for the service or there wouldn't be parties offering it, I just don't really know specific examples of uses for it because I never came across any myself. It appears to be a rare need to me, but you make it sound like some companies would want to do this so much that it's worth automating, but then I still don't know what those companies do or want timestamped by a third party (be that a notary or a blockchain).

The two Wikipedia articles I found on timestamping aren't really about timestamping of this kind. (https://en.wikipedia.org/wiki/Timestamp and https://en.wikipedia.org/wiki/Timestamping_(computing))
Hello hackernews!

I’m an accountant who got frustrated with the current software in our industry so I built my own.

The two things i wanted from an accounting system was

1) Write transactions from within my own scripts.

2) Analyse the financials directly through the database.

I love the open source work that has already been done in the space but nothing really ticked those boxes. Ledger-cli lets you make programmable scripts but it uses a text file to store the transactions, gnucash can use a SQL backend but doesn’t give you api endpoints.

Its still early stages and I have so much work to do for it to be usable enough for accountants (who will need a solid GUI). But its at a working stage if you are comfortable with CLI and SQL databases.

Seeking feedback - is this useful for you?

Anecdotally, I was once told many years ago by a woman on a date that men are supposed to like dogs, not cats, because something adjacent to "dogs are for boys and cats are for girls". The date went well, but I did not follow up.

So, I see truth in their assessment, but I strongly question their conclusion.

These days, I fail to see any need to put anything in the .bashrc file.

If there is some non-interactive use of bash, I just want a clean environment, and everything scp or ssh needs should be on the standard $PATH.

There's no point in putting anything in .profile either, because if I am running an interactive session, I will be using bash. I don't care about the config for dash or whatever.

And any scripts should completely specify their required functions, $PATH and whatever inside the script itself. Use 'source' to pull in common functions.
