Does it matter what time of the day you sleep or just how many hours?


I don't know, I've seen what temperatures have been in the past decade in Europe and I can tell that it doesn't get any hotter, in fact, it could be getting colder. Can anyone show some statistics supporting the global warming?

Edit: I know how to google myself but I am asking people to get a little more involved and not lay out facts out of memory. I thought I could make a good discussion on the topic but kept getting hostility for some reason.


https://www.eea.europa.eu/data-and-maps/indicators/global-an...

> According to different observational records of global average annual near-surface (land and ocean) temperature, the last decade (2008–2017) was 0.89 °C to 0.93 °C warmer than the pre-industrial average, which makes it the warmest decade on record. Of the 17 warmest years on record, 16 have occurred since 2000. The year 2017 was one of the world’s three warmest years on record together with the years 2016 and 2015.

> The average annual temperature for the European land area for the last decade (2008–2017) was between 1.6 °C and 1.7 °C above the pre-industrial level, which makes it the warmest decade on record. In Europe, 2017 was colder than the previous 3 years.


What exactly is "the pre-industrial average"? does that correspond to the Little Ice Age? why is that a good reference point, or baseline for comparison?

https://en.wikipedia.org/wiki/Little_Ice_Age


But 100-200 years is very little time for comparison isn't it? Is there any presumed data on what it was before that?


Loads: https://en.wikipedia.org/wiki/Global_temperature_record

Do bear in mind that most of the costs of global warming are based around:

1) It is happening much faster than we can cope with. If it was happening over 10,000 years then we'd slowly adapt. Or die out. One or the other.

2) Our cities are mostly built on coastlines, and will therefore be hit dramatically by severe weather and by sea rises.


Plenty if you care to look. See https://en.wikipedia.org/wiki/Global_temperature_record for more recent temperature evidence on the scale of a few thousand years, and https://en.wikipedia.org/wiki/Geologic_temperature_record for geologic evidence of temperature patterns over the past half-billion years.

This graph shows just how far off the norm we are for the past two millenia:

Now, it's kind of silly to keep asking HN people to google things for you. But:

100-200 years is pretty fast when compared to how slowly climate moves in one direction or the other. Also those 100-200 years are the same in which human instrialization took place. Measuring temperature in a global scale is a very daunting task and it is open to interpretations by negationists and reactionaries, but you can look for pictures of the last 30 years in the North Pole. The Arctic is going to be open to navigation soon. You can also ask the climate experts, we have to rely on them, and the vast majority of them are predicting a similar effect.


First you yourself start talking about "the last decade", and now one or two centuries isn't long enough.

You also say you think the last decade seemed colder, the reply you got was that 16 of the 17 hottest years since recording began were after 2000. But you ignore that part of the reply.

You are working for the forces that want to stop our mitigation of the problem, you are the enemy.


Telling people "you are the enemy" certainly isn't going to win them over to your side.


People who are stirring up discussions and ignore the answers have an agenda, they are trying to make it look like there is still serious disagreement about the existence and causes of climate change, because they want to hinder mitigation.

It is no use to try to win them over, that's not why they're arguing.


True, but clearly labeling people as "the enemy" might help others decide who to believe.


Calling someone "the enemy" doesn't help people decide who to believe. Belief about scientific topics like global warming should be based on facts not in-group/out-group thinking.


This might help: https://xkcd.com/1732/


Interesting. So there was a +4C change in average temperature even before the industrial age began? Didn't know that.


Over the span of 15000 to 20000 years.


Can anyone explain why Infowars are bad? I keep hearing they are but no convincing arguments to support that claim.

Edit: Do people giving me thumbs down care to explain themselves?


I can't speak for the American content, but the Scandinavian blog entries range from outright lies to gross missinformation.

Would you really want that associated with your brand? I wouldn't.


What kind of lies do they tell?



1. Sexual harassment “filed complaints against Jones” filing and proving are different things. 2. What’s wrong with conspiracy theories? Who cares unless they are real? 3. Can I see examples of fake news posted by Infowars? Still haven’t seen any. 4. Same as conspiracy theories 5. I can think of many examples where mainstream media promotes violence and harassment against right wing. 6. Chobani never proved otherwise? 7. Not sure about copyright infringement but alright, could be it 8. Unexplained suspension

Early 2000s strike back


To me it seems staged as hell. I believe it had been opened prior to “the opening”.


Did you use FlatList or ListView (or a custom module) for this? I've noticed that ListView sometimes does much better than FlatList, interested to hear what you used.


FlatList was absolutely the way to go here. In fact, we initially built the list in question when ListView was the only option. During development, FlatList was made available as an experimental component. It made a huge difference switching over to it. The optimisation we needed to do was to use onViewableItemsChanged to toggle the visibility of images. We found that otherwise it wasn't properly emptying the memory of Android devices, and it was easy to crash older devices. After implementing that, we got silky smooth 60fps everywhere.

The only issue was there was a bug in RN core. We submitted a PR which was finally accepted about 6 months later: https://github.com/facebook/react-native/issues/16612#event-...


Check out GoodOrBad - Simple Meal Logging on the stores, it’s fully React Native with some little native code (push notifications, etc.)


Checked this app out of curiosity. It’s decent but doesn’t feel native to me. Each platform has its own nuanced differences that we might think is okay to ignore but customers see through when the experience isn’t consistent with past expectations. The transition animations in some situations were what felt out of place to me in particular.


1. When the app starts, the onboarding screen appears with a flicker/glitch: https://imgur.com/IyjM82n

2. The app starts with a launch image (the logo in the center), which then fades away to show another launch image (with the logo on the top half of the screen): https://imgur.com/0n3Zbof (probably because ReactNative must load the JS bundle before it can show anything)

3. The login screen of the application fits on the screen, yet it can be scrolled up/down for seemingly no reason. The amount you can scroll feels suspiciously close to the height of the iOS status bar: https://imgur.com/P6conGz (probably because ReactNative sets the UIScrollView's contentInset incorrectly)

4. Text fields / buttons look like on a website.

5. When you navigate back from the login screen after a failed login, there's a brief moment while the "Unsuccessful login with Facebook" message is visible, which then quickly disappears: https://imgur.com/hTTKbIt

Sorry, but it feels like a webapp to me. Though it might be perfect for your use case!

Update: I've found some other issues:

6. You can't interact with buttons (e.g. "Next" button on registration) while the keyboard is visible: https://imgur.com/dpy5xv8

7. The first time you switch to a tab, it's completely empty, then suddenly the content pops into place: https://imgur.com/JKaCJED

8. Tapping on the search button makes the content of the previous page jolt against the top of the screen while navigating to the search page: https://imgur.com/BJDYvda (focus on the panda)

9. The "sidebar" menu feels very out of place on iOS. Also, when you select e.g. "Settings", the content on the right does a very weird fade/slide animation: https://imgur.com/ChNzvwW

10. When you switch between two non-adjacent tabs, the viewport slides over the in-between tabs too: https://imgur.com/BZFU0Sv


These are implementation decisions made by the author and not ReactNative issues as far as I know.

See UberEats, the former Airbnb app and others using ReactNative that can seamlessly deliver native style UX.


1. I reviewed the app. I didn't attribute any of the issues to React Native itself, did I?

2. The Airbnb and UberEats apps were written by expert native developers (I happen to know a few of them), using some React Native.

You see, expert native engineers can deliver quality apps using native frameworks. And surely, if they look into React Native, most of the time they can manipulate it from the JS side to get the desired outcome on the native side. The middleware is a hinderance for them as it gets in their way of implementing what they want in the first place.

It's like building those ship models in a bottle: if you know how to build the ship, you just have to learn how to do it through the neck of the bottle. If you don't know how to build it in the first place, well... that's a different story.


You have it wrong, only the restaurant dashboard app is built using ReactNative, that was done because they had a website earlier and they wanted to convert that quickly to a tablet app and their developers who were working on that web app had very limited knowledge of iOS/Android, refer to https://eng.uber.com/ubereats-react-native/


I definitely agree with the fact that it feels like a web app, but this is the design the customer asked for. Most of this things are actually not a React Native problem but the way the app was made. Onto your points:

1. This can easily be fixed with a module, however time pressure didn't allow for additional "tweaks"

2. Same as 1.

3. Using Scrollview for this, since some android devices with smaller screens can make the Login screen look very ugly and small, so in that case scroll looked better.

4. Do they look like or feel like ones on a website? It is by design, but interested to see how you feel about the fields as a user (although we don't support the app anymore)

5. Caused by implementation logic


This seems better than most cross-platform apps. I thought the text size was too small in several spots.


Cooking - grandma does it pretty well. I just set timers
