A big benefit of Uber is the fact it works in multiple cities. I was in a new UK city the other day, no idea where I'd get a cab from. Just opened Uber and booked one, and it worked.

Tried it again that evening and it failed -- multiple times the ride would be accepted, then cancelled. Ended up walking.

Looking at recent reviews for the Uber app it seems this is common, Uber has gone from being somewhere reliable I can get a cab, from Sydney to San Francisco to Singapore, to being something that can't be relied upon
> I’ve never seen the need for Uber

It's incredible spending time in the undeveloped/developing world - all the problems and solutions that "gig" apps supposedly are good for live on to this day all over the world.

Need a place to stay? Ask around the village and someone will be more than happy for you to sleep in the spare room for $1/night.

Need a ride? Wait where the locals are, you'll get in a communal "taxi" with locals for 10 or 20 cents to the next town.

In the Western World there are apps for this kind of thing that funnel profits to mega corporations. In the rest of the world there are average people on the street doing it every day as part of normal life.
It's a very common mistake to think that batteries are to be used to get to a 100% renewable grid.

Hydrogen can be much cheaper for (say) the last 10%, because (1) hydrogen has very low capital cost per unit of storage capacity, and (2) the efficiency hit of going through hydrogen vs. batteries is less important when it's just 10% of the total.

Think of batteries and hydrogen as analogous to cache memory and main memory in a computer. They have different performance and economic characteristics and compensate for each others weak points.

To see this in operation, go to https://model.energy/ and try turning hydrogen off and on in the settings. If you simulate for Germany, for example, turning off hydrogen can double the cost of achieving a certain level of constant grid power. Hydrogen can be particularly valuable for places with large seasonal variation or lots of wind (which has a long timescale component in how it varies.)

I will add that China is already selling electrolysers for < $300/kW, less than half that simulation's 2030 cost assumption.
Hey friends! Author (@rbluethl) here. :) I just randomly noticed that my post made it to the front page! Thank you all for your comments.
> Why not offset?

An offset would have exactly the same issues as UTC. You need the time zone location to correct for future changes. Knowing it’s UTC+2 doesn’t help with that.

Ultimately it comes down to intent, either relative to space time, or the socially excepted time in a particular location in the future. A time zone represented as a location/city name is the best we currently have, but even can can be wrong if the time zone boundary’s change.
Limiting Proof-of-Work Crypto Back on the Table as EU Parliament Prepares Vote
> Try the fact that the middle class has been gutted by an unfair tax structure

> Our tax structure is insanely out of balance. That's the number one core problem in the United States.

This is actually even worse in many places in EU. I completely agree with your diagnosis and would also like to see your solution implemented.

I have an impression, taxation here in Europe is used as a political tool to play middle class and lower class against each other. And whatever the crisis, the middle class is expected to foot the bill. All the while, the powers that be use handouts to lower class to pacify them (prevent a revolution?)

> I thought the military GPS signals were encrypted

I'm sure this is true in the sense that general publications use "encrypted" to mean, "There was some sort of cryptographic stuff involved and it went over my head" rather than actually encrypted. Like they do when they tell you that the passwords stolen in a breach were "encrypted with bcrypt" for example.

The key thing to pay attention to here is that unlike say, TLS, this is not a conversation. A GPS receiver is just that, a receiver passively observing the signals. You would usually "bend" GPS by relaying signals from somewhere or somewhen else, and the passive receiver concludes that it must be where the signals it is receiving seem to suggest it is.

Take an easy scenario, imagine I'm in a warehouse that has been designed as a Faraday cage. You've fit a handful of transmitters to the warehouse, and you play back a recording of GPS signals received three weeks ago in the desert outside Las Vegas.

How does my GPS receiver know (using some hypothetical "encrypted military signal") that it isn't in fact near Las Vegas three weeks ago? That's what the signals seem to suggest and there is literally no contradictory data available.
Good timing as I contemplate whether I want to go the Engineering manager vs. Individual contributor route.

Ask HN: Should I write a Help menu for my application?
With desktop software you used to get a Help menu which contains instructions on how to use the program and where everyone is. Now I notice these days software makers don't really bother with these menu's, especially not web or mobile software.

Should I make one or would I just be wasting my time? Have we as a society moved on from Help menus?
Indeed, it's a purely theoretical scenario, and I don't think anyone is claiming otherwise: the paper simply notes that one consequence of the theory is that information cannot exist at absolute zero, and then someone who considers this weird questions what would happen to an object storing data were this to happen. Your response was 'nothing, because data storage on space probes still works', which is a non-sequitar: the theory does not predict that data storage at space temperatures will cease to hold information.

But one specific mechanism exists: at a certain point there's entropy in simply the structure of the macroscopic object which prevents lowering its temperature further. So if you were to cool it as close to absolute zero as possible it would require turning it into something which was not a hard drive (again, this is something would occur far below the current achieved temperatures with even microscopic objects).

China is more likely to go the Hong-Kong route (https://www.bbc.com/news/world-asia-china-60474342), i.e. a very high death rate even with Omicron because they (unlike the UK) haven't managed to vaccinate a high percentage of their old population.
In typical MS tradition, there is a naming issue. Blazor can mean client-side (via WASM) or server-side.
It seems the 0-covid policy is a negative consequence of having so many people so close together. It changes the dynamic of infectious diseases so that you suddenly have 100k people die instead of 100. Still, I am strongly against lockdowns and mandates and so on. The cure is much worse than the disease from my perspective. I have no concern over covid, all of my concern is over what the government will do next. Will I be allowed to go to the gym, which is essentially a life-line for me? They closed those for months last time.
Jack Kerouac is a hot mess, in other words. And, really, aren’t we all? Does anyone know who or what they’re meant to be in the modern world? Gender is increasingly fluid, identity is a shifting concept, labels are meaningless.
Uber actively modifies the earnings of their drivers in real time, which causes the drivers to modify their willingness to accept rides in real time. The reason those drivers are canceling is because between the time they accepted the ride and arriving to pick you up, Uber modified their earnings such that it was no longer profitable, or simply worth the effort to pick you up. Uber is a terrible "employer".
Even better when paired with an extension like privacy redirect.
No, but US invaded countless other countries. One of the points of the article is that a financial war can produce as much casualties as an old fashioned war. And US can both wage financial wars and threat with such a war. So, no, US does not always need to physically invade another country. It can produce some damage by other means.
> Why not epoch?

Which epoch? There are many, it’ll change depending on your system.

Also what unit? Seconds, milliseconds, nanoseconds. That will also change depending on your system.

If someone is saying store UTC then they 100% mean store it in ISO8601 or an equivalent standard.

> Why not offset? ISO8601 is a good standard.

Because the offset for timezones change (as is explained in the article). If you just store an offset, then you have no way of knowing which timezone the user meant, and thus you can’t compensate for changes in the timezone definition (again, the primary thrust of the article).

> In my opinion there are only two ways to store timestamps that are actually correct: epoch, or iso8601. Everything else will eventually lead to data corruption.

The entire article is describing why this approach isn’t enough.
> it's usually men who sexually harass drivers... It's too bad that it hurts fragile male egos to read (or skim over, in your case) moral and social commentary instead of just dishing it out, but all the evidence supports it, so "man up".

You may share with the article writer a set of assumptions that makes it easier for you to understand what her point is. No need for hostility. I wrote what I wrote hoping that someone would explain it to me.

You correctly deduced that I am a man. As a man who does not sexually harass women and shuts bad behavior down immediately when I see it, I'm baffled by rest of what you say here. My fragile ego? Because I missed the point of the article?

I bear responsibility as a civilized human being for my fellow humans, even strangers. But it seems like you're saying that I bear culpability as a man for the behavior of the minority of men who behave violently or reprehensibly, specifically because I'm a man? Am I reading you correctly?

If that's your belief, I can understand your hostility. It would seem to you as if I'm denying my personal culpability. If that's a belief shared by the writer, it makes sense now why you understood the article and I did not.

To my mind, this kind of thinking is a category error to be avoided. It derives from assuming that, because most of the people who behave badly belong to some group, that therefore most members of that group behave badly. A corollary then is the idea all individuals of that group bear culpability for the actions of their most extreme individuals.

As a human being, I bear responsibility to end bad behavior. If I were in a group of drunken men, and someone said something so reprehensible, I would shut it down. If it was a man I knew, I would apologize profusely to the driver, leaving a big tip; I would have a series of seriously uncomfortable conversation with this man in the days and weeks to follow. But that's because I am a civilized human being, not because I bear culpability as a man for his behavior. That's the way I see it, anyway.

I have 2 related questions for you. Bear with me, and answer honestly: Are you a man? Do you believe that all men, deep down, are inherently violent rapists?

I try to neither delude myself nor others. I try to understand what makes people tick. And act the way they do.

Unilaterally declaring other insane or crazy or anything like that, while making ourselves feel good and superior, doesn't help in understanding why people act like they do.

And understanding might help in finding better ways to act and reach common goals like reducing the number of people suffering in the Ucraine right now.

Take the Nuremberg trials for example. As a German emotionally I think more people should have been trialed. More punished by hanging. Especially the SS troops managing the concentration camps. And while it would probably have felt like righteous punishment of these crazy evil German Nazi Bastards it probably would not have helped in building a stable western democracy in at least one part of Germany.

That is the reason I tey to think in understanding the motives and thought processes of people involved. Not to delude myself or argue for the deeds of Putin to be less than the despicable acts of war they are.

Putin should clearly be tried as the war criminal he is. Together with the ruling elite. But that doesn't make my need to understand go away.
I used to have a great experience with Uber.

Looking at the app store reviews in the UK of Uber, sorted by most recent

1* - Lost my trust

1* - Has gone downhill

1* - Uber Scammed me

1* - Can't get an Uber anymore

1* - The worst experience I have ever had

2* - Uber is deteriorating

2* - waiting times have increased

3* - Cancelled rides

1* Deteriorated over lockdown

etc.

All referring to the same problems I see, rides accepted by drivers, then cancelled a minute or so later.

Going further back, full of 1/2 reviews:

A sad Decline, Slow at finding drivers, Getting worse by the day, Scheduled trips are canceleld, Getting worse & worse, Most unreliable, etc

Maybe the occasional 3* but going back 6 months, "Uber is dead, No Longer the no 1 ride in London, Drivers keep cancelling, Cannot get a booking, Never any drivers, Never turned up, 1 star is too much, used to be great", etc. etc, those were back to October.

I'm not sure how long it's been going on (the same complaints go back at least a year on the reviews), but Uber don't seem to exist any more, otherwise they'd be concerned and change something to fix it.
Alex Martelli on “What's better about Ruby than Python?” (2003)
You have a timestamp in the future for example the time when a session at a conference starts. If to want to store this as UTC you will have to convert it from the local timezone of the conference location. You can always go back from the UTC timestamp to the local timestamp by performing the reverse conversion EXCEPT if the conversion involves daylight savings and the rule changes between now and the event in the future. While rare, daylight savings rules sometimes do change. I guess even local timezone offsets might change once in a while. When this happens the conversion back from UTC to the local time will be wrong unless you keep track of more than the UTC timestamp.

People have lots of things in their homes that they’re not experts at or even knowledgeable of. Most people have a hammer and nail sitting around, that doesn’t mean they can build a piece of furniture or build a house. I’ve got all the tools to make bread, but I wouldn’t even know how to get started without some practice. And the list goes on. I also have a real pen and real paper, but that doesn’t mean I can write a novel.
> 1. If you're recording an event in the past, store it in UTC.

Although it is unlikely for a timezone change to be issued after its begin date, it is likely for a timezone change to be entered into a database after its begin date. If you preserve the original local time you can always convert to UTC accurately.
Fuck, they loose their youth to this shit!

I had school 8am to 2pm and hardly ever did my homework (min-maxing it by copying, doing it selectively, testing which teachers are strict about it etc., also switched to a bi-phasic sleep pattern to cope with 8am as a night-owl).

It left just enough time to keep making music, learning to program, doing some photography, dabbling in public relations for a non-profit and of course some partying on the weekend. Once I was old enough to write my own sick-notes I would go for walks in woods instead of a double lesson of math etc.

Now that I spell it out, that's a lot, but that's the amount of life experience these kids loose.

And it's not just about temporary fun. It set me up for the further course of my life: Music brought me my best friends, programming was my entry in to a real career and non-profit work set me up to deal with people well, helping me step up to product management. I also had a few wonderful years studying digital art.

You would see USENET posts back in the 90s about C/C++ vs ASM basically arguing that C/C++ was better than ASM because hand tuning ASM wasn't worth the man-months of effort required to extract the small amount of additional performance. It's basically the same argument, writing in a higher level language provides more benefit than the performance losses that aren't really that big to begin with.

My summary of TFA:

Putin made a grave mistake and cannot win without China’s direct assistance.

Putin’s actions have strengthened US stature and position globally, as well as illustrating the importance of NATO. This presumably is exactly the opposite of what Putin desired.

China could gain influence and power by helping Russia, but at the cost of international relations. More importantly, it would still be a gamble.

Without China’s help, Putin will fail one way or another.

China could instead stand with the rest of the world. This would more quickly end the current conflict, and it would make China a more significant international partner. This is the better option.
Hey thanks for your input. These are great additions!

No it is definitely very slow. Stackoverflow did a test once, and switched to their light-weight ORM. The thing is, you mention disabling change tracking, and then there are things like having to make sure you aren't accessing a field that is outside of the included fields to prevent multiple queries, etc, etc. When I write SQL, I just write it once, and then it lives forever going very fast. When I look back on the projects written in EF/Linq, they are still going year after year, still using up lots of resources. I could have just written them in SQL. Maybe it would have taken an hour more over the entire project (internal enterprise thing), but it would still be running to this day, quickly and efficiently.
