To be honest, I dislike this sort of interviewing for DS/Algos unless the company can justify using them other than for a secret IQ test or another candidate filtering technique. If it were me, I'd just ask for links to significant open-source contributions instead of this nonsense.

Consider using org-mode [1] as your primary word processor and committing revisions to git. I recommend org-mode because org documents are saved as plain text and therefore can be easily diffed. org-mode can also be exported to many formats [2]. If you are concerned about how the look and feel of writing in plain text might impact your experience authoring a document, there are lots of editor specific tutorials for beautifying the presentation of org documents. Here is one such article on beautifying org documents in emacs [3]. Also, if you choose emacs as your editor and you are uncomfortable using git, then I recommend magit [4] because it makes git functionality highly discoverable.

Jeff, the art problems of your games have nothing to do with low-res. Baba is You (or Downwell) are just as low-res, but manage to look good because they use fewer colors and choose them well. I recommend learning that skill, it will make your games look way better and it honestly doesn't take that much time.
Mobile payments is a good one, PayPay signed up 9MM users since May last year, leading to what seems like every company in Japan starting their own payment app, with one spectacular disaster already (7pay).
It was a trick, and by politicians and people themselves, who wanted to be seen as being environmentally conscious.

The only solution has always been to reduce consumption, but deep down, everyone wants to consume more and more, while at the same time feel better about and blissfully ignore that they are destroying the environment.
Seems like you’ve never been to Hong Kong or merely stayed in Hong Kong Island or SoHo.... go outside those areas people live in some bad conditions. If fact, many fishing villages use steel sheets for housing.

Take a tour outside the shopping district or the high end business district.

Same for quite a few of our clients. Many companies were asking us for the "Vietnam option" lately, and are surprised when manufacturing in Vietnam comes out more expensive than in China even with tariffs, and usually results in them moving from a Chinese factory in China to Chinese factory in Vietnam that will still be ran by Chinese engineers, Chinese know-how and use Chinese parts.

The thing is that labour is not a big part of manufacturing costs even even for fairly low value goods, and are truly microscopic for higher value electronics. 30 years of Chinese manufacturing already drove out nearly all labour intensive processes out for production of light industry goods.

Chinese companies have moved to heavily mechanised manufacturing quite long ago. Unless somebody can master custom tooling making as well as Chinese companies, they are not going to catch up.
Sounds like the organization you work for should have spent more in security.

> "I'm tired and I don't know how to sleep"

A surprisingly common problem with very young children. Maybe also some adults.
Firstly, there isn't all that much of anything in Birmingham that makes this worthwhile. At best there might be some new business development in 10-20 years, but it's not at all obvious that Birmingham is somehow going to become London's second business centre because of HS2.

Most of the claims in this piece are simply nonsense. The Euston to Crewe train that's mentioned doesn't go anywhere near Birmingham, so it's not obvious that HS2 would make much of a difference to traffic on it.

And even if it did, it's merely one of a large number of routes heading out of London in all directions that are ridiculously overcrowded. At best, HS2 might reduce a small proportion of that overcrowding, but it's certainly not going to eliminate it.

The idea that HS2 can make Birmingham airport competitive with Heathrow for Londoners is clearly wrong. Birmingham doesn't have the flights, the destinations, or the capacity. London also has Heathrow Express for quick train journeys from Paddington to Heathrow - concourse to concourse. Even with a shorter journey time, HS2 can't match that.

And HS2 doesn't start to make sense until Phase 2 is built, linking Sheffield, Manchester and Leeds. You might see some benefits then - but the realistic total cost is likely to be the far side of £100bn. Which is madness.

It's actually five years of the total NASA budget, which is supposed to pay for development of the next Lunar program, as well as everything else NASA does.

It would be much better to spend a much smaller sum making the UK's broadband the best in Europe, set up a world-leading incubator fund for digital startups outside of London, with next-generation training and education, and try to persuade existing corporates to consider home working options. The return on that would be huge.

This is just a giant train set for rail nostalgists.

Yes. I think that some applications, with multitudes of variables that need to be shared between unrelated components, will benefit from a store that manages only those variables.

For all the other cases, I don't see any reason to use one, and my experience of the same application developed, by different people, with and without a reactive store, tells me that the solutions without a store are generally much simpler and look way more maintainable.

You don't need increased manpower to over time develop a better sense for how well your game's screens are composed and if things fit together or not. This is a skill you can improve yourself by mostly paying attention. This kind of blindness to your own game's visual quality is a common problem that everyone making a game experiences and people generally work around it by relying on feedback from other developers or from the general public, which you don't need to pay for as you can do it online by just posting images or gifs from your games and seeing how well people react.

How come the orangered envelope is cherished on reddit, but youtube discontinues the same feature? Has google entirely given up on getting a social network?

Google seems to constantly create new messenger apps. Why would they discontinue the one that could be used to turn youtube into a real social network? Instead of hiding the feature, they should enhance it and make it usable, i.e. make it easy to block harassment. Then they can offer an optional! integration with their other messenger apps which would allow them to compete with facebook.
Yep. They dropped it a long long time ago and re-introduced this in 2017(?) as a different feature.
One way to fix it is jitting.

Vacuum has only around 10% (iirc) more buoyancy than hydrogen in the atmosphere, so the gains would be very minimal while the added constraints due to having such a large pressure difference would be huge.

Earlier this year, Arlington County, Virginia removed glass from their curbside recycling program, "A significant drop in the market value of glass recyclables means it is no longer economically or environmentally sustainable for the County to collect them via single-stream recycling."

They have two drop-of locations, where residents can drop off glass "for crushing and reuse as construction and landscaping material."

Disappointed that the article alluded to but never explains why classes should be avoided in Typescript. (Which I agree, btw)

If you’re used to classes, it’s really tempting to create classes for your models. But in Typescript, which gets compiled down to plain old JavaScript, you spend a lot of your time dealing with JSON and plain old JavaScript objects (POJO). These don’t have methods. These don’t have private members. These don’t have constructors.

You actually don’t need any of that. You just want type safety around your JSON and POJO. That’s why more often than not, you’re going to be using interface.

I’m not saying never use classes. But don’t use classes to define models. Use classes for controllers.
Did that facial capture technology end up anywhere? I still remember how amazing the facial animations looked in that game and can't think of any other game since where it's been that noticeable. Although maybe that was just because of how much better they were than anything else out there at the time?

In the latter two, Twitter could easily prove that he was part of the influence network by producing the tweets that were made via his account.

And buying followers is against TOS (but do they ban people for that? #doubt), but certainly not everybody that has fake followers is declared to be an actor in a state-sponsored misinformation campaign.

The bio-degradable items won't degrade at the expected rate, as you say it's an industrial composting facility that's needed, but they _will_ degrade far, far, more readily and won't leave the environment strewn with microplastics. That's what we seek.

I've tested composting a couple of compostable nappies (aka diapers) in my under-used, low temperature, domestic compost bin. After about 3 years we emptied it out and there was no sign of the nappies at all.

If an animal eats the corn-starch (or whatever compostable type it is) cup then it's not going to be especially harmful to them. Moreover, it appears from what I've seen that the compostable materials will not retain mechanical integrity after a small time of exposure to weather, this is good too.

It's not all sunbeams though, we had a fairtrade chocolate bar for sale in our store that was wrapped entirely in compostable wrapping (with vegetable dye printing, etc.), the compostable "cellophane" wrap was incredible. Completely transparent, flexible, shiny. But [I believe] the humidity was too high and the wrap grew sticky before the shelf life of the chocolate [<1y] had come.

It mightn't be perfect but it's a good way better.

>"the big institutional lie”

The big lie is all the lavish promises people made to their future selves. Expensive medical treatments (Medicare), retirement funds (social security/pension payments), expensive infrastructure (constant access to clean water/electricity/gas/sewage/etc).

Maybe the biggest lie is pretending to be able to predict the future. All those aforementioned promises require future resources, population, growth, technological advances, all of which are just guesses as to what will be available in the future.
Honestly I think it's a shame when people are so picky about graphics. Some of the best games I've ever played were purely ASCII-based. I'm talking about various BBS games, or MUD-based games. There were also some really novel interfaces like like mTrek [0], and BattleTech 3030 MUX [1]. So much fun to play.

Vacuum airships have a long history: "First proposed by Italian Jesuit priest Francesco Lana de Terzi in 1670"[0]. The O-Boot project referenced in some replies aims to fly its first prototype on 13 December 2019 because that is the anniversary of the birth of Francesco Lana.

We'll see, but maybe it is like nuclear fusion energy - always just around the corner.

Productivity and the Workweek (2000)
Twitter made it sound like they did an investigation though. If all they did was run some script and then put everybody that shared some association on a list, that puts the whole news in perspective.
This seems like gatekeeping work.
We have had "good" (maybe not BERT/XLNet'ish levels of quality) results using ULMFit. I.e., on almost all problems we got better results than our previous best approaches (mostly LSTM/CNN and self-attention à la https://www.cs.cmu.edu/~./hovy/papers/16HLT-hierarchical-att...).

Thus, we've seen real value out of transfer learning that doesn't require overly much compute power (and actually could even be run on free colab instances, I think).

That said, I agree that the problem is still very far from being "solved". In particular, I have a fear that most recent advances might be tracked back to gigantic models memorizing things (instead of doing something that could at least vagely be seen as sort of understanding text) to slightly improve GLUE scores.

Still, I am highly optimistic about transfer learning for NLP in general

Coming from either the exchange and using the closest server to it based on latency tests (crypto) or from a provider for tick data (polygon, iex) but trying to move away from the providers and go more direct to source (easier with crypto right now).
Yeah, that seems like the best bet - either hardware key or TOTP (because, although hardware keys are better for security, not all users will have one - cf. myself), and then store your backup codes in a password manager.
Ew ew ew, that's an ugly hack if ever there was one. Anything involving CSV is guaranteed to have a nasty bite, as soon as you get CSV's "control characters" (which ones? Ha, trick question! There's about 6 sets of them in common use, almost but not entirely different.) in the mix.

TL;DR: CSV brittle, do not want.
I think that BS only persists because not just because people allow it to, but some people positively get off on it. They love the opportunity to be the hero "I was up from 4 til 7 rebuilding the database -- you're welcome" and the ability to differentiate themselves without actually being competent at their jobs.

Some roles (junior investment banking analysts, junior lawyers, etc) the long hours and weekends are part of an apprenticeship type weeding out process, and are almost a form of hazing ("I did it - you have to do it too") But at least in those cases there is an expected path out.

YouTube with a bit more work would make an amazing social network. Like games, people tend to share/centralise their conversations around a type of media - it's why Steam & Discord are now technically popular social networks.

A proper investment in a social sharing feature centred around your friends on YouTube would be a great idea. Not only for watching together with friends but for sharing it privately (just look at how popular video is on Snapchat). They even have a stories feature already - but for YouTubers to talk to fans!

I think it's still cargo-cult control theory. You can't just make your team as diverse as your market and expect results to magically improve.

Brazil's President Is Full of Shit
Ironically, President Xi was sent to a re-education camp when he was younger.
"Consider a typical working day in the medieval period. It stretched from dawn to dusk (sixteen hours in summer and eight in winter), but, as the Bishop Pilkington has noted, work was intermittent - called to a halt for breakfast, lunch, the customary afternoon nap, and dinner."

I would argue it's a flawed thinking then. If you are required to be there for 16 hours, even if you work only every second hour, I consider it 16 hours of work - you cannot do anything in between anyway. It's a bit like your if job is to sell cars and your boss only counts your time when there is a customer there and you are talking to him.
Wow Iâ€™m typing on my phone and I canâ€™t see anything. I suppose if I donâ€™t keep typing this will be all read I mean deleted. Oh well. Such is life. It reminds me of free writing. It is a form of free writing that is enforced I guess thatâ€™s useful. For things like writers block and what not.

But what am I to say? Nice product? I guess itâ€™s a cool proof of concept. But I donâ€™t see myself using it. It is more like a neat little toy, almost like performance art.

It is a new form of medium, where the rules are enforced onyoi. I suppose there are other such forms of modes. Does this bring with it anything u inquest and of lasting value? Or is it mostly single player entertainment?

I wonder if something similar can be done for multiplayer chat. Text that mimics actual social interaction in a new way is interesting. Such as IRC and twitter. Maybe even communicating with gifs.

What is looking good? To me it's that the hues and colours don't hide relevant features of the game, or hurt my eyes.

I've played on-line games that have camera shake when you make a hit, bits spray everywhere, shadows cast where they conceal relevant stuff, none of this helps me enjoy it, it just gets in the way of what I need to see. It gets turned off ASAP.

In other cases I'd rather have the characters not act like dicks (stand around when there's a fight starting, get attacked by monsters and not defend themselves). The gameplay is so frustrating sometimes. (edit: point is graphics are low on my list of bothersome)

Art is going mad, like the floppy hair that nvidia GPUs are boasting about - who cares, really?
