I've had similar experiences as a cyclist. I've gone through cyclist stop sign enforcement twice (no ticket for me as I follow the law), but I haven't personally seen distracted driving enforcement ever since I moved to Austin about 6 years ago. I've been told here on HN that Austin does enforce the distracted driving laws, but I personally am not seeing it. Distracted driving is something I see on a daily basis.

Lately I've been getting better at recognizing distracted driving and getting out of the way. I appreciate that rideshare drivers started having bright visual indicators to show which company they are driving for. Those folks are often extremely distracted. I'll also stay away from delivery drivers as they too are frequently distracted. I recall one FedEx driver who got angry at me for telling him to stop looking at his phone while his vehicle was in motion. He pointed out that it was not a phone, which didn't actually matter... I'd appreciate any other tips on how to handle distracted drivers if you are using the road.

>but probably still less efficient than trucking water in from somewhere a few hundred miles away where it's plentiful

I think the convenience and self-sufficiency factor might outweigh the raw efficiency considerations. Petrol and trucks aren't readily available to every villager. With this, there is no more worry about meeting the water truck and doing without. A big concern is what the lifespan of MOFs are. If it can be used for decades with minimal maintenance, it could be a game changer. If not, it would be back to the water truck!
Purple+Mattress+Savings
You have to keep in mind that trucking in water isn't feasible in a lot of places. Sure, in developed nations there is a good road infrastructure, but it's rarer the further out you go. And it's usually the further out you go that water is more needed. Then, even if you do have a road, have to consider the water truck breaking down, the driver not showing up, etc.

Even in developed nations, a water truck doesn't always work, for instance dirt roads with steep inclines and sharp turns.

> renewable electricity has a short-run marginal cost of zero

This seems to be the crux of the argument. It certainly doesn't make sense to me. Obviously oil would find it hard to compete with electricity if it was free, but amortizing the cost of renewable power plants means that is unlikely any time soon.

Not just Namecheap, there are so many other options. We're not trying to replace designers or these free websites. We're providing an alternative that we believe is better because of several reasons.

- Our system figures out your needs by just looking at the description you provide. You don't have to select anything else to create very relevant logos to your brand. This is not the case with other websites where you have to provide plenty of information or at least do significant customizations.
- Not one of these websites are generating icons from scratch. We will in a couple of weeks/months. This is going to be a very exciting feature that will set us apart. Let me know if you want to talk about this in more detail.
- Our system learns as more people create logos. We have a feedback loop that continuous retrains the models to improve the logo creation process. In a few months, our logos will definitely be way better than free websites and other competitors.

Finally, at the end of the day, we still offer an alternative that we think has better features. If someone chooses to use a free website, by all means.

Mm are you using Lambda as a sort of router?

The linked project is developed by Amazon and it translates into native Lambda layers. If they did their job with performance (which I trust Amazon devs to do), there should be no difference.
Thanks for feedback! Any naming suggestions? :-)
No thanks. The benefit is not having to specify the plan. The optimizers themselves are fairly good. A well designed table with the right indexes should perform well.

Raw SQL is great at what it does.

ORMs are typically good at what they do.

Depending on the use case both have their pain points. Typically I see a mixture of ORM for most CRUD based stuff and raw SQL for cases where the ORM isn't suitable.

No need to throw the baby out with the bathwater.

I think they are talking about fertilizers, not fuel.
True. If you go k levels deep you get indexing complexity of O(k) (because you do a constant time operation for each level) and insertion/removal complexity of O(k + n^(1/k)) (because that’s indexing plus a linear insert/remove operation for the array at the bottom). If you push k towards log n you get O(log n) for both. (I’m ignoring rebalancing issues here but these can be dealt with too)
The article did mention that you can push k to values larger than 2 in the Generalization section. I think it would’ve been nice if they had explored such values when doing the performance tests, but either way I found it clear and nicely written.
I'd be amazed if this is true. Especially as Waze has a GPS based speedometer built in that goes red if you go over the speed limit.

I image it looks at a combination of speed limit, current traffic and then if the historical data is faster than the speed limit it discards the historical data.
It seems very unlikely that the majority system used (especially outside the US), would not be exploited - maybe they try to separate and say not the exact same webpage hosted Android exploits.

The beauty of an ORM is that an ORM backend can be adapted to your proposed system. Or at least some subset of the ORM's spec can be. You can get a nice language specific API for common patterns, migrations, and the power to drop down to system specific escaped SQL queries when necessary. You get a layer of independence, in case you really want to switch to another backend for some reason.

"Our system matches keywords to clipart" seems like a more accurate description, it's not really designing anything, is it?

This is awesome feedback. Thanks.

A couple of points. You are right when you say it's a long process but I believe you'll agree that it's not long for everybody. There are so many new companies that just want a decent and affordable logo as quickly as they can. Those are the people we are targeting now.

Regarding your comment about the logo concept - we are working on some deep learning architectures that generates the icon (concept) from scratch. That feature will take some time because of computational reasons but once that's in place, even startup founders who want to go a few rounds to get their logo concept would be able to use our website.

Let me know if you want to talk more about how we're gonna do it. Thanks again for your feedback, it's awesome!

Say you have a given amount of water vapor in the air. Relative humidity as a percentage reflects the amount of water vapor in the air compared with the maximum amount of water vapor the air could hold at that temperature (and pressure). The amount of water vapor the air can hold depends on the temperature, with higher temperatures able to carry more water vapor.

As the temperature goes down, the amount of water vapor stays the same while the amount the air can carry decreases, so the relative humidity goes up.

Could you share more details about what’s happening behind the scenes? I mean this in the spirit of constructive feedback but the logos it generated for my business just seemed to a random mixup of color and type combined with a freely available icon pulled from one of those “free icons” websites.

I don’t really see where the ML plays into this. Cool concept though, I’d love to see it ask me if I like such and such and refine the process a bit more to land on something I actually like.

Right now, yes. But the main reason behind having a generic product is our long term vision. We wanted to get our initial product out and immediately start working on other features. One feature that will answer your concern here is icon generation from scratch using GAN architectures. We're working on it and it'll take some time but as soon as it's live, not only will you be able to use existing stock clipart, you'll be able to generate logo concepts from scratch.

This is by no means the final product that we want to have in a year or two. There was a reason we named the website "designwithai". We kept it generic because there are so many features that we're gonna add that are purely AI driven.

We can always talk more about the other features we're thinking about.

Adding to this, the issue was not directly with the cameras themselves but with the length of the yellow light. In order to increase revenue from traffic cameras, municipalities were reducing the amount of time the traffic light was yellow. However, reducing the length of the yellow light also leads to an increase in car crashes.

Outside of racism, sexism and homophobia, I'm not sure what you are referring to. Any examples?

As a fellow AR lover the only things that consistently bug me are when it does things like:

- .count on a collection calls SQL every time, but there is also a .count method for arrays - which means you need to remember to use .length if you just want to count the objects loaded into memory

- ‘build’ methods for an association usually only initialize a record in memory, but with has_one associations it deletes any record that already exists

So basically when it’s not clear about the fact that it’s doing database things.

Lithium batteries aren’t green at all. Going to EVs just changes the impact on the environment.

If we can’t solve the end of life issues with lithium batteries, we need to look at them as a technology adjacent to petroleum when it pertains to environmental impact. A true step forward would be an innovation of power storage itself, rather than the mechanisms around it. Build a better gas tank.

How many times do you touch the stove before you get cynical and expect hot stoves to hurt?

Desiccant/absorption dehumidifiers are nothing new. I've been around the block enough times to recognize the hype cycle. The motivation of the inventor seems pure, and the first order analysis seems to make sense. Dehumidifiers do indeed pull water out of the air, so it seems plausible that this tech could one day be used to quench the thirst of people living in deserts. The moller skycar scam has gone on for decades in no small part due to how reasonable it sounds. We know machines can fly, so why not a road-worthy aircraft? On the surface it makes sense, so the scam finds plenty of marks. But the devil is in the details.
Oh definitely. Here are some of the areas where ML comes in.

- The colors you see are generated by ML models, not us. If you don't like them, just hit the dislike button and our ML models will soon stop creating them.

- Icon selection based on the description is not an easy problem. You have to understand the semantics of what you're trying to say and match those with an icon's appearance. We're using word embeddings and auto encoders here.

- Initially, a genetic algorithm generates a bunch of stuff but that gets pruned by ML systems. As we get more feedback, that ranking/pruning is going to be more effective.

- Which fonts to combine together is not trivial. Convolutional neural networks come to the rescue here.

- Finally, one of the additional features we are working on is going to generate icons from scratch using GANs.

I hope this answers your question. Let me know if you wanna talk more about how we go about doing everything. Always happy to chat.
Looking at the release notes:

> Go 1.13 now requires macOS 10.11 El Capitan or later; support for previous versions has been discontinued.

> Go 1.13 now requires FreeBSD 11.2 or later; support for previous versions has been discontinued. FreeBSD 12.0 or later requires a kernel with the COMPAT_FREEBSD11 option set (this is the default).

Sounds like they're still using syscalls directly on those platforms. Is Google ever going to admit that it's broken by design, because userspace apps on those platforms (outside of the base system, which is tightly coupled to the kernel) are not meant to be calling into the kernel directly directly, and should do everything via libc and other userspace libs that wrap syscalls?

I guess it depends on the nature of your work. If you're doing any kind of analytics, window functions are indispensable for their ability to have a set act like a list.

The Gig economy jobs are a race to the bottom of the pay scale now. You can get the least expensive services by using workers that have no insurance, vacations, sick days or any type of benefits but is that the work environment that we want to encourage? I get it. It's nice to be independent but it's even better to have a job that lets you have at the very least a satisfactory life.

Technology can give us jobs that free us from the traditional chains that we all know but we also need to figure out how to make sure those workers don't get exploited.

Technology is just part of the answer. We also need to have social and political changes. So we can have the jobs that we want without destroying the worker protections that our previous generations have fought so hard to gain.

Making sure that there are laws that protect workers is the start. The answer to the right pay for the gig economy workers will come. But we can't do it by removing all benefits from the workers and not have any other way for them to get them.

I know one thing. What Uber and Lyft provide is needed so companies will figure out how to provide it even with new laws.
No one wants to (or should) spend too much time on a logo as opposed to focusing on their business.

Yet, most founding teams I've met end up spending a disproportionate amount of time (though not much money) discussing or changing their logo.

Also, startup founders usually only do this a few times. Web design consultants would do this more frequently.
One additional thing I'd like to add here. Those icons are not free and we have to pay a subscription fee to download them and use in our product.
I agree with the parent comment that the twitter logos are much better than the ones currently on the website.

> Whatever the DB engine can do with queries hand-written on top of views, it can also do it with the query generated by SQL Alchemy.

No, on two levels. Firstly, there are many features in SQL that an ORM will not support (e.g. no substitute for a materialized view).

Secondly, once you get really good at SQL, you learn that very tiny seeming things can make the difference between a query running for an hour or a second (e.g. case-insensitive search against an indexed column). Part of being expert in DB technologies is knowing how/why some ways of writing a query are very fast, and others are very slow. The idea of an ORM is to hide that complexity, which is fine for a toy todo-mvc app. But once you start querying tables with 100k rows you need to understand that complexity and master it if you want to write a fast query.
That seems fair. We are definitely going to add an iteration process that you can go through to end up with something you like. Thanks again for the feedback. It's super helpful in improving the product.
Aside from the fact that there isn't much water in dry air, 2257kJ of enthalpy is released for every kilogram of water pulled from air and that's a lot of heat to get rid of somewhere. Most mature cooling technologies (peltier, compressor,etc) have a COP value smaller than 1 so in other words it will take even more energy to harvest water efficiently. Trucking water might actually be cheaper.

I think the idea is that they want to catch people specifically for cell phone use. I get the feeling they've got some harsh penalties for holding a phone at all while driving.

They can pull 1000 people over for various offenses like drifting out of their lanes or failure to signal but that isn't going to put fear into people like it would if all of those 1000 people were busted for driving while holding a cell phone.

People tend to overestimate their ability to drive well while playing with their phones and if you're caught but the officer doesn't see it in your hands it only takes a second to drop it into the seat next to you.
