I expect more than half to worry given the number of children in food insecure households, the lack of retirement savings many americans are confronted with.

Much of it still survives -- freenode.net IRC, instant messaging, email, independent blogs, domestic and overseas message boards. It's just that back then that's all we relied on. Nowadays many people may or may not check their email, but they always check their Facebook page. Lots of them browse it on a device which listens in on their conversations and monitors practically everything they type (Android). I myself am typing this on an Android.
Not exactly related to big corporations getting control over the Internet, but I remember when I was 12 I would browse all day on underground hacking sites.

These sites had usually a dark theme, the hilarious feature of blocking right click (usually followed by a JS alert saying something like "Copyright - create your own content") and several script kiddies tutorial. There even were some phreaking articles!

It wasn't that long ago, maybe around 2005, same period I started using computers. I wonder, do websites like these still exist?
Are there any others that you find useful that aren't suggested here?
Has it been figured out which adblock list accidentally blocked AMP? We'd like to contact them.

American schools do that as well to varying degrees. In addition to that, they send out cumulative grades every semester or half semester. In theory, these grades should not be a surprise, but parents don't always follow the daily grades their child gets; particularly those parents which might be abusive.
I think it's your latter point that's the key issue. This is something that has been able to be predicted from years ago. Most people do not use phones for many hugely intensive tasks: email, messaging, audio/visual (music, photos, videos), and a handful of generally low resource cost apps. Like you mention it's exactly what happened to PC. Phones that are now years old can perform these tasks practically just as well as new phones and will be able to do so for the foreseeable future, so why would you buy the new phone? The fact that new phones have become much more expensive is just going to accelerate a process that was already happening, rather than being a cause of that process in and of themselves.

And really this process has repeated in countless consumer hardware products besides PCs. Televisions were another example. The change from CRT to flat screen was a pretty big change. And the TV's kept getting bigger, flatter, and with better image quality. But eventually people decided that their TVs were big enough, flag enough, and looked good enough. And so TV sales have begun their extremely predictable plummet.
That’s both an upside (as you’ve described), and a downside because the already challenging environment of molten salt becomes increasingly radioactive making servicing even harder than the chemical and thermal environment of the salt make it. You also have to carefully monitor the salt, and a lot of the probes and other means of monitoring it tend to rapidly degrade in the molten salt.

It’s another issue that feels like the answer involves new materials that have a much longer life in situ, so that the inevitable maintence is infrequent. It’s a very promising technology, but it isn’t mature yet.

Individuals hosting servers with whatever functionality they wanted that people would connect to, substantially spread by word of mouth (like MUDs and IRC channels) but otherwise difficult to search. People would link to others they found interesting in "rings" to help visitors find new people to read, and often online communities were made up of a lot of people who knew each other in person and wanted a way to communicate from home more easily.

Information you found was generally published or organized by a passionate individual, for instance if you wanted to know about Star Trek you could find a star trek website that had factoids assembled manually by a few people. So you can imagine that the information was probably pretty reliable, delivered without commercial intent, but the breadth of availability was limited to what individual people felt like publishing.

In the beginning, I remember borrowing books on the internet from the local public library which had a CDROM that had basic software like mosaic to browse the web, and many would provide IP addresses and port numbers for public FTP servers containing things like freeware games and open source software. I was about 11, I'm not sure how adults at the time got online but it's probably not that far different.

Basically, imagine the entire content of the internet being like open source -- if someone was passionate about something and wanted to share it it was there. If not, it wasn't. Servers were often located in people's homes, I remember many times services just not responding because the hosts home internet was down.
I remember a time when search engines were just link directories. Finding stuff was hard but at the same time we used to pay more attention and read through the information, I feel like now attention span is very short.

I did not know Apple Music was on Android. I wonder if they're using FairPlay (used on iOS and macOS) to do DRM or if they use Widevine?

Apple Music's recently released web portal uses Widevine to do DRM (same as Netflix and Spotify web) https://tools.applemusic.com/en-us

FairPlay on Android surely has some bugs if this is the case ...
Cheap .net packages, shitton of advertisement, constant discounts and offers, and more importantly they own the domain market.A lot of people buy domains from them and it doesn't take long to host something on that domain, so why not stick with them. Long story short, the power of convenience.

Isn’t that kind of the point. A conservative approach to adding features so that they can be at least implemented well and understood?

What are the main, real benefits slack has over IRC;

* resilience to network disruption

* onboarding of new users.

* inline media (clients, not protocol, should implement this)

You could argue threads or SIP/VOIP but my admittedly anecdotal evidence suggests that these are seldom used. And, there’s no reason IRC could not expand to relay those.

> I'm glad I've wasted their time

That's an odd attitude. You've also wasted your own time, yes?

Wait, there's another approach.

Sign the non-compete, and let them sue you, if they even notice that is, after you're in the new place. I had a boss that did this (which I saw happen live) nonchalantly. And managers are worth going after more than individual contributors in many cases. In the most recent case they went after him and New Company's lawyers came to the rescue. For those readers not in the US, those of us commenting from within the US have different laws in different states. In New York State, the judges typically respect non-competes for one year (even if it says 1000 years in the contract).

One employer of mine tied stock options to the non-compete, in a totally separate document from the offer letter. There has to be something material, otherwise, what are they going to do, beat you up? A restraining order so you can't go to New Company?
The following is not common knowledge, but I'm fairly knowledgeable in the area so hear me out :)

We thought for a long time that neurons were fairly easy to imitate. After all, most of what they do seems to be exchanging neurotransmitters, whereas internally they have an electric potential which is encoding most of their behaviour. While not easy, individually they are also not super duper complex compared to say, a microprocessor. Taken from this perspective, it looked like the main difficulty was in simulating them in large enough quantities to obtain interesting behaviour.

The argument in the paragraph above is foundational to how we think about intelligence. There are various other aspects to it, like morphological intelligence, but the above seems the most relevant when we want to create an artificial intelligence. While these days there are also more engineering-focused arguments for why we think artificial neural networks are interesting for research, underlying there is the idea that the only intelligence we know is made out of small simple things in large quantities that exchange simple signals. This is a key thought when you want to use artificial neural networks to create artificial intelligence. For instance the Human Brain Project in the EU (cost ~1 Billion EUR) is kind of built on this argument.

Now, and this is very recent research, this foundation is starting to shake from the biology side. It appears that neurons are also exchanging RNA, trans-scripting the RNA received into proteins and that those proteins seem to interfere with the transmission of RNA by the neuron [0]!

That is something completely different from the argument I poned before! In a computing analogy, every single neuron is a computer which is receiving and transmitting program code (RNA) and executing code it receives (transscription) and we know that the program it receives is interfering with the neurons receiving and transmission of programs to other neurons.

If intelligence does require such complex mechanisms, we are VERY far away from simulating (or understanding) that at scale.

Now we don't know whether this complexity is necessary. But the old argument of an upperbound to the level of complexity needed seems to be crumbling too.

All in all, putting some real neurons might prove to be a viable alternative for creating artificial intelligence, as it might circumvent the problem I sketched above. It might not, but it at least seems to be a direction worth exploring as a second bet next to simulating neurons.

That'd be why the new generations of airships are not lighter than air but mix buoyancy with a lifting body: hybrid airships retain some of the low operating costs and long range of an LTA airship, but because they're not actually lighter than air they can be landed on the actual ground and secured more conventionally.
That's a justified question! I'm using DCG (semicontext) notation here analogously to monads, mostly to benefit from having to keep track of fewer explicit arguments that need to be passed around.

In this concrete case, using them explicitly is certainly not bad and may even be preferable. However, suppose I now introduce a new argument in order to implement iterative deepening:

turing(Ls, Name, Tape0, Rs) :-
phrase(turing_(Ls, s(q0), Name), [[]-Tape0], [_-Rs]).

turing_([], final, _) --> [].
turing_([_|Is], s(Q0), Name) -->
state(Ls0-Rs0, Ls-Rs),
{ right_symbol_rest(Rs0, Symbol0, RsRest),
tm(Name, Q0, Symbol0, Q, Symbol, Action),
action(Action, Ls0, Ls, [Symbol|RsRest], Rs) },
turing_(Is, Q, Name).

Then this notation, in my opinion, already makes it a bit easier to think about the rule, since it only uses 3 arguments instead of 5 or more, and the tape is simply passed along implicitly.

An iterative deepening version of the machine provides the important benefit that infinite branches of the computation cannot block others that lead to (nondeterministic) succcess. For example, suppose I add the indefinitely looping machine:

tm(loop, q0, 1, s(q0), 1, right).
tm(loop, q0, b, s(q0), b, right).

and then define:

tm(loop_or_plus1_or_id, Q0, S0, Q, S, A) :- tm(loop, Q0, S0, Q, S, A).
tm(loop_or_plus1_or_id, Q0, S0, Q, S, A) :- tm(plus1, Q0, S0, Q, S, A).
tm(loop_or_plus1_or_id, Q0, S0, Q, S, A) :- tm(id, Q0, S0, Q, S, A).

then we now get solutions via iterative deepening, whereas the original machine loops without reporting any solution:

?- length(Is, _),
turing(Is, loop_or_plus1_or_id, [1,1,1], Ts).
Is = [_3790],
Ts = [1, 1, 1] ;
Is = [_3790, _3796],
Ts = [1, 1] ;
Is = [_3790, _3796],
Ts = [1, 1] .

Iterative deepening is an asymptotically optimal search strategy under very general assumptions. Thank you for the kind words!
It's been the longest shutdown ever. A short shutdown doesn't usually effect very much because departments have extra cash in the bank. This time it's going on long enough things are actually starting to shutdown.
It can go both ways - often the insurance negotiated price is significantly cheaper.
Everytime it looks like there might be a shutdown, affected agencies are supposed to start planning for it and get all this stuff together ahead of time whether or not the shutdown happens. Takes a couple weeks. Is a real waste of time.
The thing has a cargo capacity of 20,000lbs who is this for?
Military? This thing can only carry 4 humvees at most and about 1/6th of a a main battle tank by weight.

Civilian transport? 20,000 lbs is a lot if you need to resupply an Arctic research station manned by 3 people but not for anything at scale.

Tourists? Maybe a novelty but you wouldn’t really need more than 1 or 2 of those.

Edit: 1/6th instead of 1/3rd forgot that MBTs are 60,000kg not lbs.

Three-phase AC also allows for very electromechanically simple generators and motors. Industrial electrical loads have traditionally been (and often still are) rotating machinery, putting three-phase at an advantage.
The sample story:

"Carla bought a hairdryer with a 6-month seller's guarantee. When it broke after 8 months, she took it back to the shop. The shop assistant told her that her guarantee had run out and that she was not entitled to a refund.

Carla rightly pointed out that she had a full 2-year guarantee free of charge under EU consumer protection law, and that the seller's 6-month guarantee only offered additional services. The shop agreed to replace the hairdryer."

So it broke down after 8 months, meaning it was not faulty from the purchase time and it was over the 6 month period you are referring to. Either that is wrong or they are not interpreting the law correctly themselves either.

Show HN: Foodspan – Reduce your food waste
Hi Hacker News,

For the past few months I have been working on a tool around helping people with their meal planning (meal prep).

After doing some customer research via Facebook groups and Reddit /r/MealPrepSunday (check it out!).

I found that meal planning individuals had these 3 problems:
1. Budgeting
2. Food waste
3. Finding recipes

And so Foodspan was born (lifespan + food) to tackle this.

Foodspan is rather simple, it works by:

1. Estimating a recipe's lifespan whether in the fridge or the freezer.
2. Estimating a recipe's cost per serving.
3. Alerting you when your cooked meals are about to expire.

When released it will cost around £10-15 a month. I plan to add features around discovering cheap long lifespan freezable recipes.

I would love to hear your feedback.

That smacks of the infamous "gap left by the dark ages" chart, and doesn't really account for the drop in innovation across the Roman world in the 1st and 2nd centuries CE, when large parts of the empire (indeed, notably excluding Greece) were not Christian or minority-Christian. Unless you are supposing some crucial difference between Hellenism and its Roman adaptation?
"It is possible but not reasonable to believe, let alone act on."

It's not a matter of believing. It's about understanding you may not know everything there is to know.

I'm old enough to remember when a guy came back from Mexico and said "they have a plant there that, when rubbed on your skin, will prevent sunburn" and most everyone who was considered an authority said he was a "fool".

They could not have been more sure he was too. They were "100%" sure he was, so they didn't act on it.

I'm pretty sure most of them were using "Sunblock" just a few years later though.
The BBC article isn't great and leaves you wondering why it was approved at all. The Guardian article is better but still isn't great imo. It's as if they're intentionally sowing seeds of unease about these types of ships even though this was just a test aircraft.

> An eyewitness said the aircraft appeared to "break in two" after breaking its moorings and deflating...

Why would they approve it after such a mishap one might wonder? Well the deflation was intentional and triggered by an automatic safety system as The Guardian article explains.

> Another mishap befell the 92-metre-long (302ft), 44-metre-wide craft in 2017 when a woman was taken to hospital after its hull automatically deflated when the vessel came loose from its moorings.

But it still frames it as a series of mishaps and injuries. Which I guess is great for page views but damages the reputation.

No, historically that's not been true. You'd see slowdowns at the end of the fiscal year as contracts and other things change over or have to be renewed (so one office is busy making the contracts and others may be slowed down waiting for them). But a full on shutdown has been rare.

Most departments, however, do contingency planning so things like this should be available with minimal tailoring for the current situation.
You're kidding about those numbers, right?

An optimistic but realistic scenario is something like 40% faster and $20 a month, where the phone is used a lot and the speed translates into saving multiple hours a month. Definitely worth it there.

You don't need to be especially sophisticated to enjoy some basic advantages of DSLRs - eg aperture priority (you tell the camera what aperture size you want, it works out exposure time and ISO) is an easy first step. (This controls, essentially, what bits are in focus for your shot.) Plus it's a feature few phones offer, or indeed can do much with, as they have such a tiny aperture (5mm of glass to let light in, say).

Increasingly I'm happy enough with a phone (giggle pixel 1 which has a halfway decent camera + software support) for walkabout use, but the benefits of a small DSLRs for holidays or other special events is hard to beat.

Thank you very much for taking the time to answer in such detail. It does confirm my suspicion that most of my use cases are already adequately covered by JS/TS/Node and that there's not some killer hidden feature that I am missing.

The links you sent in particular answered a lot of questions for me. Seems like one of the biggest draws (for me at least) is that python is slower to change over time. That cannot be understated and is my biggest frustration with the JavaScript world. That is, the unending need to learn the new "Obviously Best Way" to do things every 12 months or so. It gets exhausting.

I'm naturally curious so I'll keep learning python. Can't hurt right?
Does anybody know a good math course covering all the high school and college subjects implemented in a collection of flash cards? I have no idea what do "normal matrix", "diagonalizable by" and "unitary matrix" mean (of course I can look these particular up) mean so far but I feel like I would like to try learning up to this level (including what I've learnt in the college and completely forgotten right after the exams) this way.
They’re also making phones that are less comfortable to hold. But taking away the headphone jack is a non-starter for me. The FaceID “only” thing is a deal breaker for professional reasons. I also can’t stand the notch. They clearly don’t like the notch, either, since they hide it in all of their marketing. I’d rather they removed the selfie camera and relocate the speaker to the top of the phone.

Love my SE. The size is crazy portable. It’s even a little too thin for my comfort. But it’s so thin that a battery case isn’t a problem.
