I have exclusively been driving EVs since 2013 (Renault Zoe and a Tesla Model X), and also use a Brompton folding bicycle on my commute to work (total 6 miles cycling).

I've never understood the appeal of electric bikes. It just seems lazy to me. I'd feel guilty if I relied on the motor instead of burning calories.

I use the cars for transporting the family, or to go long distances quickly. I'm not averse to cycling 25 miles if time allows, and I've also managed to carry all sorts (like IKEA furniture) on my folding bike. I also wear my work clothes (jeans and t-shirt) when cycling on my commute, demonstrating that lycra is totally unnecessary!

I can only assume that electric bikes are for people that wouldn't normally cycle, or whose routes are prohibitively hilly.

Would be keen to hear the use cases of anyone here that uses one.
It's not good. That's what natural trust networks are meant for, and developing your own skill to protecting yourself, your family, the circle of people for whom you bring or consider within your circle - of whom you associate with hopefully without external pressure, although it certainly happens because of bias or vested interests.

It shows a lack of integrity of the individual, and is a slippery and dangerous slope as Hitler and and the SS would want or require you to report your neighbours, etc - and it sounds like this is all without due process. If the Chinese people knew this literature, this history: I don't know if they do know, or what version they know, or if they know the similarities between what China is doing and what Nazi Germany did - which is where the grave concern for the system/layer of censorship is what I pointed out.

I do have compassion and understand that if merely associating with someone with a "low social credit" brings your own credit score down, that based on if people do indeed know and are quiet about not talking negatively about government, then they may be doing so to protect themselves. They won't however know then if they distance themselves from these people what happens to them, if they are taken off in trains to "rehabilitation camps" for "rehabilitation" or murder.
It’s a paradox because many people find it counterintuitive. It’s the mathematical statement of why correlation does not imply causation. The existence of a confounding variable correlated both with the purported cause (eg gender) and the purported effect (school admissions) can lead to reversals in observed association when grouped or broken out. Thus it is challenging to draw causal conclusions from observational data.
For me the key take away on the Spark bit was on the security of software for autonomous vehicles. Java, .NET, and Julia do not have similar security and verifiability features as Spark. Although, I was playing with F/F# for this. F compiles to OCaml, F#, or C via KreMLin.

It's not even close to being the same.

Your US credit score is an assessment of your risk to potential lenders based on different factors. The alternative is that only rich people get credit, because they most likely will pay it back...which used to be the case 30+ years ago.

Every person I know with terrible credit has access to all of the things you mentioned.

China's system is based on things like your friends and your opinions of the government and is just a way to control the people.

It's also mandated by the government. Last I checked, Equifax can't put me in jail for a bad credit score.

Totally different and scary.
I don't think Instagram, one of the most used software user interfaces think redesigns are a waste of time, they redesigned to be similar to Snapchat and was able to create a new user experience that engaged users and was able to be monetized efficiently through advertisements
Still I think part of the problem is that you can't opt out. If I wanted opt out and you tried to look me up and it said no info. Well that means you as a lender then choose to not lend the money or just assume highest risk or limit risk by loaning only smaller amount.

People should be able to opt out.
It’s interesting to think about the origin of the many ancient myths and legends about human behavior during full moons (i.e. insane behavior, sleepwalking, criminality,accidents, etc) and the possibilities of even that small amount of light (as generated by a full moon) having an affect on human behavior and emotion, especially during times of our evolution when the alternative was a nearly pitch black environment.
Yes absolutely! Random assigment along with statistical power and significance considerations does indeed allow one to draw causal conclusions. It’s the gold standard for causal inference.

This is interesting, though it really shouldn't be specific to one RDBMS (and I like PostgreSQL).

To be honest, I don't find the status quo particularly difficult to deal with. A directory with lots of little files doesn't take up much storage, and nobody cares about the space anyway. That said, improvements are always welcome.

I like how it looks at the diff and figures out simple schema changes. However, in my experience, the simple changes are no big deal. The more interesting challenge in migrations is when semantics change and you need to generate data from existing data. Simple diff cannot determine that, that needs to be provided by some set of queries, which easily fits in a migration file.

Is there a way to integrate more complex changes and dataset manipulations when needed?

I've been wanting a 12factor-type methodological doctrine for data for a long time. Ideally, one that can fully account for how, when, and why to start introducing different kinds of databases and when you need to start exploring those options.

But I'd be happy with a lexicon and fundamental strategy for managing data that allows you do relax and rely on the fundamental primitives, like 12 factor does of overall application architecture.

A lot of that isn’t the redesign itself, but the fact that almost no one designs for the change event itself. It’s a whole different problem to solve, and it’s usually just dropping you into something totally different without context.

A nosql database schema change would force you to update every document requiring the change.

I would say rdms schemas are straight forward. Remove constrants, alter tables/move data, add constrants.

Changing a nosql schema going forward is simple. Adding new columns is equally simple. Deleting columns: rdms is much easier. Updating rdms is simplier.

Build Your Own Delphi Based Operating System
^^^^ This. A thousand times, this. ^^^^^

As a supporting example of the arguments, I recently had to replace a subtly corrupted table in production with one rebuilt from trusted sources. The table was about 160k rows and core to the operation of the production system I work on.

The initial "easy" approach to replacing this table took many hours to execute, and locked the table for much of that time. It took a day or two of effort, but the final series of SQL operations pushed the total run time down to less than four minutes, was recoverable from any intermediate state, and pushed the locking time down to three seconds.

The complicated part was not the final state of the database, but finding a path to reach that state that fit within the operational constraints.

There is a balance. If aesthetics are a limiting factor, as determined by research, then they’re worth improving.
I think you're partly right that it is true in any area. But I don't think it's equally true in every area, and I think that UX lends itself a bit more to subjective artsyness than software development.

But I generally agree with your sentiment; you can absolutely find "just trust me" in software development. You can also probably smell it out better by learning about it more.

I think you're just trolling, but let's assume you really believe NYC is a representative choice for a "major metro area" and not simply one of the most expensive cities in the world to live in.

> After taxes that $700k turns into $450k.

You're talking about capital income - taxation varies around the world.

> NYC 3br apartment in a good neighborhood costs ~$3M, which roughly translates into $200k/yr

If you have $10m in the bank, buy the apartment and these $200k/yr will be 0 (just maintenance/running costs) and cost you $210k of your capital income, but pre-tax. You just won $65k/year plus the yearly increase in the apartment's value.

You can't be serious. This is far from "basic".

My point was that even concluding this were true basedo n some compelling evidence, it still doesn't explain all of the strange qualitative aspects of our subjective experience. There's a lot missing that needs to be explained. For instance, such an explanation would have to address p-zombies, Mary's room, and other philosophical puzzles. I think it's possible to do so, but there is an explanatory gap that needs filling.

An arbitrary, short, upper limit is also an externally detectable code smell of a site that potentially stores passwords in plain text.

If the passwords were salted and hashed (preferably with a KDF) then the output of the salt and hash stage would be a fixed length value, independent of password input size, making external, small, limits of maximum length unnecessary.

Instead, a statement of "maximum of X" where X is small like 16 or 20 or some other number implies that the storage for the password is a char(16) or char(20) column. Which also implies plain text storage.

I've been riding one as my exclusive mode of transport around the city for about 9 months now (though I just got an electric longboard and have been taking it on short excursions). It is just wonderful. The biggest bonus for me is that I'm able to pretty much keep up with traffic to the point that people are not driving dangerously around me in a bid to pass me within inches. I'm also able to get places faster, ride farther out, and use it for trips I may otherwise have not (and didn't) use my bike for. I do live in a pretty hilly area as well, and making 10MPH up a fairly steep hill certainly makes things "closer".

You would think so, but the amount of 'developer superstition' and and 'gut feeling' I've faced in development is quite high.

This is the exact feeling I've been having for years, nicely described in an easy to understand language. At least in data science and (god forbid) behavioral psychology, you can answer any question any way you like - statistically valid - by slightly shifting the level of focus (as described here), definitions or angle of attack. The more data, the easier.

Thanks for putting it in such a clear way :)

I have office installed, but I'm not using it often, so I have no idea about its shortcuts and I'm not going to learn them. Menu allows discovery.

Ribbons have less items than menu and they are not very well organized (there's only one level of hierarchy), so I'm often stuck not able to find something.
Arbitrary limitations on characters, esp. on the set of punctuation style characters like the above, is an externally visible code smell of a site using plaintext storage of passwords.

If the passwords were properly salted and hashed (preferably with a KDF) then the output when shown to humans would normally be a hex encoded string. With only the characters [0-9a-f] appearing in the hex encoded string, there is zero risk of SQL injection, so there would be no need to restrict the users from these characters.

Restricting the characters implies that some portion of the system handling the passwords will see the raw input from the user and might break should those characters appear. But a properly hashed password up front would insulate those systems from the users input. So a character restriction implies a lack of proper password hashing, and a lack of hashing implies a high probability of plaintext storage of those same passwords.

Bingo. Back in the day the person I reached on that first phone call really did give a shit _and_ they had the skillset combined with the authority to find and implement solves.

At the end of our working with them whether the person I spoke with cared or not wasn't the issue any more: it had taken 30 minutes plus to get to them and it was a very junior person who didn't have the skills or authority to run an ls -la from the bash prompt.

Prepaid sims (and entire phones) could be bought in cash back in 2001.

Also credit history is not in real time, so any purchases made while running around the mall would not be reflected that day for credit application purchases.

Who cares? Compatibility with insecurity is not a goal.

Maybe this was a 2001 thing, but you definitely do not need a credit check for prepaid plans. Maybe you were also financing your phone?

>"Well here's a free credit card application. We'll give you a credit card immediately. Run around the mall and buy some stuff."

This sounds suspect as well. I've seen in store applications, but they never give out cards to use on the spot. Also, I highly doubt that they would give a credit card to a non-resident with no credit history.

> Their stated requirements boil down to snake oil and laziness.

Without knowing the internal structure of these particular organizations at all, that's quite a bold claim. If a company has a half million employees and their technology supports billions/trillions of dollars of transactions, it's quite likely that "laziness" has nothing to do with upgrading the entirety of the IPS & DLP products they support, to say nothing of solutions on the client or server side. They can't just edit some config and make all their technology magically support a new protocol that is explicitly designed to stymie their efforts.
