> But this chaos—this unpremeditated waltz of oops, no, you go and nope, buster, me first—is reality. It’s how cities work. Which means that if a car is going to drive itself, no humans drivers involved, it must get really good at interpreting and anticipating the behavior of human non-drivers.

I'm not sure why it's always pushed as a near unattainable problem to have cars react in a human-ish way in situations as these.

All it needs is machine learning of thousands of situations of purely human drivers or watching other cars around driverless ones, and adapting the models to be able to apply them in particular situations. Such as a 4-way stop or someone rolling through a stop-sign.

It seems this obsession with defaulting to what the idealistic but unrealistic safety-first situation is (as say, designed by idealistic traffic engineering and law enforcement) vs focusing on learning to drive like humans with the least amount of errors, where rules are more flexible and risk is evaluated without much loss of safety.

We live in a very tightly controlled rules based society on paper, which seems like a major roadblock these systems have to confront, as they seem to pretend real safety is following these existing rules exactly. Yet it sounds like it would be far better if it broke the rules about 10-20% of the time... like most humans do for the sake of efficiency and merely adapting to the situation rationally.

We should be giving the machines as much, or more, leway as humans, much like how we hardly give jay-walking or going 10km/hr over the speed limit a second thought - but applied to a much larger group of compromises.

This may be a bit of my own libertarian bias that I have, a worldview where chaos is okay, and encouraged, as long as no one gets hurt (to a reasonable degree). But the actual problem sounds to me that the traffic rules aren't well adapted to machines yet, which tend to take them far more literally than humans, rather this idea being pushed that the machines are navigating the rules poorly.

>> A photo of your photo ID card, taken in front of today's physical newspaper clearly showing the date, or over your screen showing your open ticket needs to be added as an attachment to the ticket.

I thought you were being sarcastic, but the page you linked indeed states that.

What is that for, a hostage negotiation? Proof that the time machine works?

How many people buy physical daily newspapers in this day and age?
My car has adaptive cruise control. It automatically paces the car ahead with about a 2-second gap. It is absolutely wonderful for reducing stress and workload in heavy traffic. But the other cars... Someone will see the gap and race around me to fill it, as if I wasn't driving exactly the same speed as the car ahead. Causing my car to slow a bit to rebuild the gap. The next car back sees that and decides the first car passed because I'm an obstacle, and copies them. And so on. Until I'm driving 5mph slower than traffic, with a constant stream flowing around me.
At my last gig we had three support channels: phone, skype and ticketing. Standard workflow (which clients always tried to circumvent) was: client writes to skype/calls, we decide whether complaint is solved by a quick explanation and respond with a call, or problem requires more investigation/work and client is directed to submit a ticket.

Everyone should offer support every once in a while. Say one day a month. Good managers do this themselves - I think Jeff Bezos does this.
I imagine you could encode the problem as a CSP with each of the legal/contractual factors as a constraint. Despite NP-hardness of CSPs in general, CSP solvers are pretty efficient if the constraints are sparse enough and not chosen adversarially.
The local newspaper reported that the state government is asking for Aadhaar when distributing free HIV medicine. That seems a lot more problematic.

At the heart of it, it is still very much a rules engine, but also comes with the bells and whistles to create a full blown web-based implementation easily.
Did you also know that a sufficiently smart compiler can deduce the whole programming logic from English prose?

It's just pretty hard to create one. Same applies to automatic optimizations in the general case: what do you exactly know about what Java does beyond that it is capable of using SIMD instructions? Have you perhaps evaluated how and where it does so, or how the end result compares to more explicit manual use of stream operations?

edit: and for the record, the problem is not as easy as you seem to think it is, given how you described your astonishment.
Yes, this can happen in a few different ways and is the reason why Ycombinator created SAFEs. When you have a public company you will get offers for what are called "credit lines", "debt financing" or "convertible notes". They are traditionally used to create death spirals https://www.investopedia.com/ask/answers/06/deathspiralbond.... as the size of your float increases by you, executive director (CEO/CFO), as a public company "issuing" more stock to cover the loan. The more you issue, the less you're worth until somebody comes along scoops you up and re-engineers the cap table which is a restructuring. However, manipulation can occur within institutions as well: https://news.ycombinator.com/threads?id=KasianFranks&next=14...
Yes! Both of those are excellent.

I can’t even install 10.13.1 on my Mac Pro 2013 - computer acts like its bricked until rebooted a number of times (and when it finally boots we’re back at 10.13).

This also means I can’t install the latest security update that fixes the root problem (and yes, i’ve changed the root password to mitigate).

OSX is becoming more like Windows every day.
Agree, I fail to understand what you mean. If I'm a large owner of a POS coin, why would I want to steal smaller owners' coins ? Don't I want them to trust the system and keep buying more coins ?
Laws have been passed for that, and we should keep passing them, but it hasn't had the effect you posit on bitcoin mining.

Obviously there is motivation for Triplebyte, as any recruiting agency, to pick data that is lower. This encourages engineers to accept offers from TB clients vs others. (Similarly, promoting higher figures to companies/clients encourages higher offers & higher close rates.

The problem is the process is only indirectly driven by the real problem you are trying to solve and the feedback loop is slowed down 100 fold.

In reality you might look at an API for a couple of hours and realise it isn’t suitable. Maybe in fact you realise that using an external API is the wrong approach altogether.

This kind of think, investigate, tinker, evaluate, change loop happens hundreds of times in solving a reasonably sized 6-8 week feature.

If you have to stop and wait for the next team meeting before moving forwards to the next iteration of the loop you are in trouble.

In reality it causes developers to stop thinking or caring about solving the actual problem optimally. Instead it becomes all about just finishing the next ticket and leaving the hard thinking to once a fortnight.

I got multiple calls from 4 numbers since maybe 3 months ago, and when I Googled the number, I found a nice information at https://www.lemberglaw.com/lemberg-law-uncovers-dirty-dozen-... that those numbers have been investigated by some law firms. I think we should always report those numbers to the authority, and let the authority do the rest.

Compared to the average adventure game that came before it, Myst was actually fairly straightforward in how all of its pieces interacted. Especially because players had basically no inventory.

King's Quest seems a more fair comparison IMO.
The airline made an honest mistake (clearly they didn't want this to happen), and the union laughs in their faces and the contract they pushed prevents the airline from doing more to remedy the situation.

I'm obviously blaming the airline first. But the obvious remedy is to pay the pilots even more than 150%. I wonder what the ultimate solution will be. Maybe it'll be easier to weasel out of it by yanking vacation from employees than simply paying 300% (or something).
Sure, it's fine for daily use, but my folks live about 400 miles away, and I visit every couple months. That's an extra charge on the way there, then another on the way back.

And it's not clear to me just how easy it will be to use a supercharger if Tesla sells as many as they intend. How likely is it I'll get a slot without waiting the week of Thanksgiving?

My situation can't be that uncommon. People take vacations, visit family, go to conventions, etc, etc. I realize if it's just once or twice a year you could rent a car, but it doesn't take that many rentals to put you into the "wish I'd bought a regular car" group.

The only way I can see a car like that making sense is if you're part of a two-car family and the electric is a dedicated commuter.

"other functional style syntaxes like pattern matching are being introduced in many of them"

The Interpreter and its dual the Visitor GOF pattern have made what amounts to pattern matching possible in OO languages for a few decades now [1].

The whole point of these patterns is to write recursive functions following recursive data types, which is one of the main use cases for pattern matching (ok, more generally these are used to break data structures apart).

In particular, if you look at an example of the Visitor pattern, you will see that it has exactly the same structure as a recursive function that separates cases in a FP language [2]

Here is a detailed explanation of how to do it [3]; it is the "little language" technique (which I suspect is the reason why it is called the Interpreter).

I knew about PV vs. HVM, as that is documented. However, there is a ton of nuance in this article about every instance type and specific changes to what parts of the system are virtualized (and in particular stuff with EBS, which I stress heavily). I guess you are saying that people need to essentially find all of the old blog posts from AWS to figure out any of this, but why isn't it just documented? I clearly am someone who cares a lot about these things, or I wouldn't have posted the question I did: but Amazon's instances are essentially just black boxes. I am hoping that there is somewhere in the documentation that I don't know about that just shows the differences between all of these instance types in a few centralized pages.
#1 could be solved by having a scheduled key rollover system, anchored robustly by the central bank (eg public display of key fingerprint at headquarters).

#2 doesn't sound any different from other fiat currencies or bonds issued by nation states. It's in the issuer's ecnoomic self-interest to preserve their credibility.

O'Reilly's “Programming Rust” by Jim Blandy Available for Kindle
The rivers weren't remotely good enough, which is why the Erie Canal was dug. For the first 70 years, commerce east to west had to go around the horn of S. America, and the economy still boomed.

The explosion of the railroad system solved those problems, but that was around 1870.

Massive oil, gas and coal reserves are hardly unique to America. Oil, for example, has made Saudi Arabia very wealthy, but not an economic powerhouse.
Front-end handbook 2017
The majority of the employee pool in America is in a deeply economically precarious position. A month or two, or even a few hundred dollars make the difference between being able to house and feed their family or not. Employment in America is a gun to the head. The idea that choice is a factor in accepting (or doing anything to retain) a job is the delusion of a privileged few.
If you don't care as much about usability and care only about speed, there's already stdsimd which allows you to invoke SIMD intrinsics directly.

Ask HN: Django templates are a tad bit annoying to set up. Right?
So, I like django templates, a lot, and I have used them quite a bit. The sheer variety of built-in tags and filters and the ability to define custom ones is great...

Here's what I don't like: the effort that goes into setting up a fresh template starting from a raw HTML page.

Every time I start a new project I need to lookup-up django docs for these info nuggets:

- Where and how to place the template in the project folder

- How to deal with "static assets" such as JS, CSS and images

- Painstakingly inserting static tags and wrapping the 'href's and the 'src's in it ...

Besides, the above is just the necessary first step and the real work of wiring-up the context variables is still ahead of us...

When I had freshly started with django I did find this a tad bit overwhelming. Today, if you are a fresher to django - do you feel this way?

After working on several django projects I find this "template deal" to be somewhat of an annoyance. If you are a django veteran - do you too feel this way?

Would love to know your thoughts and opinions on this.
Well, I guess I was assuming they were tackling that problem or had some way of addressing it. That assumption was based on trust, evidently misplaced.

It does seem like a hard problem to truly solve. The difficulty of doing the crime is so low compared to the difficulty of excluding anyone who might feel slightly inclined to commit it that it seems inevitable that removing humans is the only viable solution at scale going forward.
Your safety advice is completely unreasonable to follow on highways. When you give that sorta advice, you make safety worse not better.

It takes about a 100 yards -- a full football field -- for a normal passenger car to react and come to a complete stop.

https://www.qld.gov.au/transport/safety/road-safety/driving-...

This is equivalent to 4 full seconds of following distance, which is double the typical 2-second-rule recommended by transportation governing bodies.

https://en.wikipedia.org/wiki/Two-second_rule

If your suggestion was taken seriously, it would literally halve the carrying capacity of our highways.

Luckily, situations where the vehicle in front of you comes to an instantaneous stop are extraordinarily rare, basically requiring a head-on collision.

This was very well written. Effective communication with people is far more challenging (and rewarding) than the communication with devices that we developers do on a day to day basis. It’s easy to get lost in that cloud, and lose touch with the people we’re building for.

In startups, this aspect can too quickly get shunted off to a QA or CS personnel, and problems get abstracted into incident tickets (that are often ignored in favor of the Next Big Feature). That seems to me to be giving up one of the classic fundamental advantages of a small business: the personal touch.
Same thing for me with Battle.Net

I moved to Singapore. Their purchases are region locked (and may they burn in hell for that alone). Tried to change my account's country, but that requires submitting your ID and your address, the latter has to be verified by either being shown on the ID or by .. submitting a utility bill or something related.

For a game account. For a change that is irrelevant and only matters because of their shitty business practices in the first place.

I would argue that the behavior of unions in Argentina has more to do with Argentinian culture than the strength of the unions. In Sweden unions are also very powerful (to the point where e.g. laws about minimum wage don't even exist since that's covered by the unions, and unemployment benefits to a large portion are distributed by the unions rather than the state), but Swedish culture has a stronger emphasis on consensus so the results are different https://en.wikipedia.org/wiki/Saltsjöbaden_Agreement

It could mean that unions or some forms of unions (state-backing etc) are incompatible with certain cultures though.

Exactly. And the old K&R Unix that sits beneath it all may have been stretched to its limits. Time to switch to a modern operating system with a proper security model.
It seems this service is targeted towards specific applications where write traffic is somewhat independent between 2 regions. However, you can shoot yourself in foot, if 2 regions are trying to update the same row, because of eventual consistency.

I find that neuromorphic chips are in this awkward valley where they aren’t trying to be state of the art machine learning systems (TPUs and GPUs do ML much better), but they’re also not trying to emulate biology faithfully. I think experimenting with new hardware and technologies is great, and I hope we discover something really useful from these. Still, I cant help but wonder whether they should be more focused in either practicality or pure science.

Wow what an incredibly insightful comment! As someone who has worked in support, dev and management I’ve developed practices to mitigate the issues you’ve mentioned - namely rotating devs “on duty” availabe for support tasks and have a dedicated channels for communication where people are not left “talking to the hand” - their words :). But I have never actually thought of it in such a holostic way. Would definitely use it in the future when I’m designing or fixing a company process :)

I’m not sure if file sharing is broken for me. I don’t use it right now. But I’m afraid I might run into this bug in the future when I eventually use file sharing, and then I will have forgotten about this fix, and end up spending hours scratching my head and head-desking.
More senior engineers will get an extra 10-25% each year essentially automatically.

The reason part of your salary is a bonus rather than the base is so that it can be withheld if necessary, eg in a bad year. Believing that bonus is an automatic extra 10% will, one day, leave you 10% short of your expectations.
> NOT HIPAA compliant

While you're likely correct, there's really no way of telling if they are compliant or not without a published 3rd party audit (ideally several). If a company puts the proper policies and controls in place, and then proves implementation and adherence to a 3rd party, then they are technically compliant (be that HIPAA, PCI, etc.). It is possible to define and implement data access policies for offshore workers. It's extremely hard to prove adherence, but it's possible.
