The UX had changed and neither of us could find the option in the touchscreen menus. Even pulling out my phone and searching Tesla's documentation didn't work because it was out of date and wrong.
Historically, lots of countries had laws saying you had to enclose your land. If you didn't, then you might lose it.

In the days before wire, brick walls were a cheap longlasting enclosure method, especially if wood or stones weren't easily available.
This isn't a question of regen braking through.

> climbing a mountain and then going down the other side does cost more net energy than driving the same distance on flat ground.

You say this, but your reasoning is regen braking? What if you never had to brake the entire way? Where did all the energy going going up the hill go? If I carry a sack of sand up a hill and drop it, the amount of energy it has falling is equal to the amount of energy lifting it up the hill. Why does this then magically change when that sack of sand is now a car?

That's a Tesla problem. They couldn't figure out blended braking. If I press the brake hard in my car, the regen goes to max possible.
Western Europe has always been cleaner than both Eastern Europe, and the US, but things have been backsliding.

Things have recently changed for the worse. eg. I was in Paris, and I could see a stark contrast between now and 10 years ago. Also, parts of Italy seem to be backsliding, and then you have parts of Croatia that look better than many western parts.

Ps. In the US, NYC and SF are pretty 'dirty' overall, but then you have mid tier cities such as Miami, Boston, D.C., that are and feel very clean overall.
Luckily most states have provisions that don't allow red-light / speed cameras in general. And we should keep it that way.

I'm stuck wondering what can be done. We've all seen FAANG companies go to court for breaches of users privacy. A browser engine monopoly doesn't seem to be something people care about. They don't know what an engine is, and can't see how one owner would be a problem.

The problem is Google, being such a large company is far to powerful to compete with. Not to mention they own a lot of the products on the web that other engines need to be compatible with to be usable.

What should be done is Google should be broken up so it's no longer one company leading this thing but I can't see that.

The hardware failure was on the server running the application code, so RDS replication wouldn’t have helped. You’re right of course that this failure points to a lack of redundancy – but that’s a separate issue from choosing S3 vs. RDS as the data layer.

By the way, S3 is insanely reliable and in fact more reliable than a replicated RDS setup. So switching from S3 to RDS would almost certainly reduce the basic reliability of the data layer, however many conveniences it might bring.
Both Tesla and this seems to be veering into the territory that VW did back then with emissions.
I'm not defending the choice to use S3. I probably wouldn't have made the same choice. But I am pointing out that it's empirically wrong to say that storing data in flat files necessitates the considerations of an ACID-capable RDBMS.

But to your point, if your system requires less than a thousand lines of code to open a file, do basic parsing and processing (which no data storage system is going to do anyway), and write the output to another file, I personally can't say that Postgres or MySQL or any other solution is really worth the effort/cost to build and maintain. In the system being discussed, the benefits of an RDBMS simply don't matter: any strongly consistent key-value store would work.

> Complex is Greenspunning a database and having it blow up in your face and cause a twenty-six hour outage.

S3 didn't cause the outage, and from the look of it, neither did the code that processes the files. It was an application logic problem which caused issues during the restore process, and this would have been an issue regardless.

You could make an argument that the recovery being slower than it could have been was a problem, but it's wild to say that and imply that traditional databases have no performance cliffs. Especially when dealing with corruption or data recovery. Raw file storage will never have a Postgres transaction id wraparound incident (see: Sentry outage for most of a day in 2015, MailChimp/Mandrill for over a day in 2019) or have to rebuild a critical index.

In this case there was a hard coded concurrency limit with S3 of 250 outstanding requests. Bumping that up to 3000 would have been easy and reasonable (S3 rate limits at 5000). How confident would you be that your database can performantly handle a backfill during recovery? Have you provisioned enough iops? Are you running an RDS instance with only a burstable vCPU limit? To say Postgres is "rock-solid" (and make no mistake, I am a Postgres fanboy) dismisses the many and varying ways that it can fail in unusual and surprising ways.
The article says it was a mandate from Elon Musk. Not sure I believe the claim, but I'd also be surprised if he wasn't aware just how optimistic the EPA estimate is.

That's like saying "reading the future from chicken entrails is a skill".
One thing that I found counter-intuitive is that building a device that periodically receives data wirelessly is generally more expensive on the battery than a device which periodically transmits.

Naively, I assumed that it must take more power to transmit than to receive, which is true on an instantaneous basis, but false on an average basis.

A device that wakes up every so often, transmits, then goes to sleep can use very little average power as compared to a device that must constantly have the receiver powered up to listen.
I suspect that another reason might be that the mechanics of competitive gaming focus on maximizing players' control over whether they win rather than on maximizing joy.

It's like the difference between backyard football and professional football. In backyard football most people play with house rules that make the game more fun but less competitive. On the other hand, in professional football the rules are designed to help ensure that the better team wins.
I was very surprised to see all of the negative sentiment on the other thread [1].

The prevailing opinion seemed to be "just use a real database," specifically in the contexts of testing. As in, why test against a mock adapter when you could test against your actual DB (or sqlite), with very little concern given to the adapter pattern in and of itself.

But I think that sentiment misses two points:

1. The adapter pattern is a pleasant API from a user perspective, regardless of your approach to testing.

2. As far as testing goes, why not both? You should absolutely have functional/integration tests against a real database, but pure unit tests are also useful for highly portable test environments. This is especially true in larger orgs where you can't just ship a Dockerfile to everyone to ensure they all have a consistent dev environment.

There was also a concern about adapters hiding the SQL that gets run, or making more queries than is needed, which makes it difficult to debug query performance. I think this is the most valid argument against the pattern, but it's not an insurmountable problem.

Very few people attain EPA average efficiency, so insisting on putting a range indicator based on EPA averages seems silly.

Most ICE cars calculate range based on a long term average of a person's usage with some small amount of pessimism. Why should an EV do worse?
Not at the moment, but that's possible to implement by extending the emulator and this webapp. This implementation was more inspired by something like twitch plays pokemon (multiple users competing for control), but on a smaller scale and also playable with more realtime titles.
Really? Or you meant the other way around ?
Sharing some context here: in grad school, I spent months writing custom data analysis code and training ML models to find errors in large-scale datasets like ImageNet, work that eventually resulted in this paper (https://arxiv.org/abs/2103.14749) and demo (https://labelerrors.com/).

Since then, I’ve been interested in building tools to automate this sort of analysis. We’ve finally gotten to the point where a web app can do automatically in a couple of hours what I spent months doing in Jupyter notebooks back in 2019—2020. It was really neat to see the software we built automatically produce the same figures and tables that are in our papers.

The blog post shared here is results-focused, talking about some of the data and dataset-level issues that a tool using data-centric AI algorithms can automatically find in ImageNet, which we used as a case study. Happy to answer any questions about the post or data-centric AI in general here!

But this use case covers the majority of drivers in the US.

The vast majority of people I've personally talked to concerned about range could absolutely charge at home and rarely drove more than even 100 miles.

Has Brave made their own "extension store" yet, or are they still piggybacking off Google's? This could be the way they set themselves apart; neither Google nor Mozilla do a good job of vetting extensions in their 'stores', both are packed with all manner of spyware. If brave made their own extension store and actually vetted extensions like Debian vets packages, they'd have a good argument for not being thought of as merely a chrome derivative.
The average person is reasonable and could probably be trusted to do the right thing. It's the 50% below average whom I'm worried about. You'll probably find a Pareto-like distribution on littering, i.e. ~80% of the litter is produced by ~20% of the people.

Actually, gas cars have the best range on highways because the engine can stay at peak efficiency, electric cars are best in the city because they only use energy when moving and can recover energy from slowing (i.e. stop and go). And others mentioned that heating is free in gas cars (in fact it might improve your cooling and thus efficiency).
The quick summary is VirtualBox vs kvm/qemu is a classic commercial product vs open source comparison. Without going too deep into the actual architecture, VirtualBox is much easier to get started with (although check out something like Proxmox), but qemu is much more powerful. AFAIK, there are no features in VirtualBox that can't also be done with kvm/qemu, but there's a lot of things that can be done with kvm/qemu that can't be done in VirtualBox.

I say kvm/qemu because the actual hypervisor is kvm, while qemu is used for control and device emulation. qemu can also emulate full machines, which is obviously much slower but can be extremely useful.

My PHEV VW car shows range which is estimated based on the petrol level and the battery charge. I learned this the hard way because I noticed my petrol tank was very very close to empty driving on the motorway. I simply engaged fully electric mode, which turns off the petrol engine, and that way made it to the fueling station.

It sort of learns based on the immediately previous drive what the driving style is, and therefore what the range is.

> The federal government has absolute authority and supremacy on this matter

No, it really doesn’t. It has absolute authority over interstate commerce and federal property, among other powers. It has no constitutional authority to regulate intrastate commerce.

It also has the power to impose excise taxes, but I think that constitutionally must imply reasonable excise taxes: i.e., it may not impose a $1 billion/quart excise tax on ethanol rather than amending the Constitution to permit federal prohibition. I can see how reasonable people might disagree with that reading, but in conjunction with the 10th Amendment I find it compelling.

The Constitution is really not that complex a document. It doesn’t always say what any one of us would like it to say (and we are free to advocate for its amendment!), but it pretty clearly says what it says (most of the time … there are a few gaps, as above).
Pathway (https://github.com/pathwaycom/pathway) is a data processing framework we are developing that unifies stream and batch processing of large datasets. It lets developers concentrate on writing the data processing logic, without worrying about tracking changes to data and updating the results. The same code can then be run on batch data (e.g. during testing) or on real-time data streams (i.e. online query processing)

In the LLM app, Pathway allows concentrating on prompt building and querying the LLM APIs as if the corpus of documents were static, while all updates to it are handled by the framework itself.

> *A straight wall of the approximal strength and length of a wavy wall, not just length.

The article suggests that, if you attempted to build a straight wall with a similar amount of bricks, that it would not be able to be freestanding (i.e. it would need to be buttressed or it would fall over). That's a significant feature of a wall to some people, so I don't think it's fair to dismiss the utility of that by suggesting that it's simply "less bricks for comparable strength," it's "less bricks for a freestanding wall."

If you want a freestanding brick wall, this seems to be the "ideal" way to do it, assuming you have the space required for the wave. I think the space needed would be a function of the wall height, so if you need a tall wall, you need more horizontal space for the wave and a wavey wall becomes less ideal.
