Really great, thanks for the resource!

I've had ideas in the past for websites or projects where I would have wanted to use HTML5s canvas, but I haven't ever known where or how to get started. The demo here seemed very straightforward and easy to understand.

EDIT: Upon further consideration, this will actually be perfect for an upcoming project that I've been neglecting for a while due to not knowing how to do the drawing aspect. And it works with React ️

I prefer extensions that work without you creating an account on something. I am unlikely to use ones that require an account unless I am desperate to use it. I am also unlikely to use an extension when either a web site or desktop app will do.
If a car is 100x the embedded energy and lasts 5x as long, then the car takes 20x as much energy per useful year. This doesn't count the energy to run each of them, which is more lopsided obviously.
Those back muscles are doing a ton of work keeping you from falling forward. They don't work as much in the squat as in the deadlift, but they still do a lot of work in the squat.

The amount of work the lower back does is directly related to how far forward the body leans (at the hips; I'm assuming we're not discussing bent-back lifts). The lower back does a lot of work in a deadlift to counteract the torque the weight creates via the upper body lean. In a low-back back squat, the amount of work the lower body does is reduced somewhat because the lean and therefore the torque reduced. It's reduced even further in a high-bar squat, and in a front squat the back muscles are mostly doing isometric work in conjuction with the abs to keep your spine from collapsing.

Even if your squat form is bad and you're leaning excessively, you're probably not putting more stress on your back than in a deadlift. Unless maybe you're dive-bombing your squats and letting your lower back round a ton at the bottom.
Another potential data point on this is parking minimums, as that's a signal whether personal vehicle ownership patterns are _actually_ changing.

The parking spots built with a new condo development have an enormous cost which impacts everyone: https://grist.org/cities/parking-rules-raise-your-rent/

So it would be interesting to examine whether these minimums have been eased in cities where ridesharing is popular. If so, that's definitely a win (potentially also for the local mass transit advocacy groups— this is a popular talking point).

I keep looking for a smartphone in a feature phone's body.

I don't care about a big screen or zippy processor. But there's all those handy little apps on Android that I'd have no replacement for.
So the accepted wisdom is "Raise yer prices", regardless of anything else?
Why does this app want permission to tweet on my behalf?
Some forms of revenue from videos in addition to the ad revenue are Patreon as well as product placement / referrals.

Now, consider that even old videos continue to make revenue over time.

In my case, if I was going to use YouTube as a source of income I would see it as passive income to supplement an existing income rather than a full time occupation.
I think this is in the very least partially a result of a broken market. Due to regulations and zoning you can barely call development a market. It takes lots of effort and ideally connections to build something. Meanwhile it's largely a seller's market. If we dramatically reduced zoning restrictions we could get much closer to the market doing its work and maybe have some real competition.

For example where I live so malls get built by the same developer. Even if someone wanted I'm sure it would be nigh impossible to get permits etc. to build a competing mall next door and try to drive them out of business like in a real market. I'd love to see real, break neck, free market competition for all projects and no schmoozing with the major.
Modern discrete GPUs also have IOMMUs and per-context page tables. It's a large attack surface which has received relatively little attention from hackers so far compared to CPUs, but there are hardware-level security features in place.
Ask HN: How do I learn more about China?
Over the past few weeks I've been reading more and more about Chinese current events. Usually things related to government actions as most of my readings come from the NYT, Washington Post, or things posted here on HN.

I'd like to learn more about Chinese culture but do not know where to start, some of the topics I'm interested in are:

- Confuscism
- Mao
- Chinese Communism & Past Political Systems
- Modern Chinese Business Culture
- Modern China (in general)
- The Chinese Economy (past, present & future)

Please feel free to suggest books, documentaries, articles, blogs and other types of info that can help!
I’ve been thinking about this lately and I think the challenge is that your competitors in sales calls can reference and undercut your public pricing easily.

This assumes your customer segment shops around and are price sensitive.
You aren't getting anything resembling Tarsnap's security from S3 or GCP. If you don't care about security (and for some data sets, you totally don't!), you're right, it doesn't make sense to use Tarsnap.
But it does have dependencies (as any shell script tends to). e.g. it requires openssl for computing hmacs; and it needs either curl or wget for doing http requests.

Also, Why would someone prefer this over https://github.com/lukas2511/dehydrated ?
This was incredible! Thanks for sharing. I wish they taught more of this kind of thing in grade school. Do you work in the dental field?

I've been reading about xylitol lately, a sweetener found in sugar free gum. From what I can tell, it could potentially help with cavities because it can help regenerate dentin. Not to mention gum seems to be generally helpful for removing waste from teeth. Is this something you've heard about?
I like the fact that there are plenty of demos!

He's being sarcastic. He could answer his question with a five second Google if he had a genuine, sincere interest in learning about the subject.
Not a very good article. The underlying studies are pretty weak so I would say the jury is still out on ride-sharing's impact on congestion. I advise anyone really interested to read the actual research as this has become highly politicized.
Worse than Minority Report because at least in there they were actually seeing the future not predicting it.
I bit the bullet and registered with my real email address. The email from solani reiterates "If you don't want to use your real E-Mail-address, please use an address from the top-level-domain ".invalid""

Where/how do I do that now that I've registered? They don't seem to understand that, to me, giving them my real email address just to sign up is the same as "publishing" it.
One of the things I value about Tarsnap is that I can set a permission which does not allow data to be deleted. That is, if a hacker somehow gains access to my server, she cannot delete all the existing backups.

More generally, I suspect you are underestimating the number of people who tick one or more of these boxes: (a) Impressed by Colin's security chops and the security focus of Tarsnap such as its Bug Bounty program; (b) Have never heard of BorgBackup; (c) Value customer support; (d) Are worried that an open-source project would not be maintained and prefer a vendor whose livelihood depends on the product (d) Have experience with Tarsnap on previous projects; (e) Only need to store 20 Gb and for whom saving $5 per month is unimportant; (f) Have revenue in the millions and for whom $75 per month is a rounding error.

Even if there were no such people and Tarsnap's new user growth was zero, it might still make sense for Colin to triple the price of Tarsnap in order to maximise the income from existing users.
I’m a fairly new TiVo user and have never experienced any other DVRs. The appeal of TiVo for me is a few things:

- skip mode: while watching certain shows that were previosly recorded(mostly prime time) you can skip commercials at push of a button

- ability to stream or download shows onto mobile device. We download kid shows onto the iPad and they’ll play offline, and you can even delete the original off the TiVo

- ability to manage recordings and setup one pass from mobile device. (One pass is a feature that lets you record all episodes of a particular show)

- user interface: I never used the old interface, and have not used other DVRs, but the latest interface is really nice. I rarely use it to manage recordings but when I do it works quite well.

I’m probably an outlier in that I never had cable my entire life. I recently got cable and watch quite a few shows regularly. I never watch commercials and get to enjoy TV on own own schedule.

Long form TV, like sports, or live shows, and things like the olympics olympics are great to speed through the boring parts and watch what you want.

Oh I certainly hope usage of buses doesn't decrease. One person hailing an Uber takes up an entire car's worth of space on the road: 4 seats, an engine, and a trunk. One person riding a bus takes a single bus seat on a vehicle that can hold 20+ people in a minimum of space.

If each individual hailed a single Uber for each ride, it's obvious congestion would greatly increase versus each individual taking a bus, simple because one person in a private car takes up much more physical space than one person on a shared bus.

(I hope Uber doesn't continue to increase for many other reasons, congestion being just one of them.)

Read vs write has nothing to do with serverless, it's about well-encapsulated logic that doesn't need any server management and has granular pay-per-use billing.

It doesn't get much simpler than a function that does a key/value lookup or returns a text file; what exactly is over-engineered about that? The app is fast, it's < 100ms which is perfectly fine for non-cached access. This isn't mission critical real-time, it's a completely free service to lookup a password hash.

Everyone here is caught up in the usual "we can do better" perspective without actually thinking about why it was done this way. In reality the current method is cheaper, more reliable, more scalable and has 0 maintenance compared to anything else suggested so far.
Can photons interact? If they can, what happens when you have two photons cancelling each other out at different distances from their origin? From the photon reference frame, both were emitted and absorbed at T=0, but in our reference frames they were emitted at different times.

Does that somehow link the emission time of the two given that there is a reference frame in which they are equivalent?

This is in fact not idiomatic Go style. The Go error idiom is that errors are values, and that if you want cleaner error abstractions, you just program them yourself. People make trees of errors, or aggregate errors and check them once, or have error stacks.

"continue" doesn't recover from an error, obviously. It is not hard to find screwups in error recovery code in Go.

Your "fmt.Errorf" "idiom" (it unfortunately really is one) is one of the major Go error handling warts. Since you (like everyone else) didn't create an error variable or type to capture any of the meaning of the error, what you've created is a by-design unrecoverable error, one where your only hope of responding in any way other than aborting the entire operation is to parse the string error message, which is something more than one Go program has had to do.

I don't think this is a very strong rebuttal to "Go error handling kind of sucks".
This is written by one person who is one small part of gun culture. There are lots of angles in "gun culture." I live in a place that goes pretty strongly pro-gun. I think that most of "gun culture" around here is not much connected to the gun culture described by this author.

A lot of the gun supporters live in rural America and only experience the types of threats related here when watching Hollywood productions. Everybody these days is feeling the threat of all the mass shootings, but very few in rural America have been personally touched by them. They also haven't really experienced gang violence, home invasion, mugging, etc. We all know those things happen, and some feel some distant anxiety about them. But most in rural America have not experiences them except through news reports.

Yet, gun support is strongest in rural America. Some point to hunting. Some will talk about self-defense. Many are just enthusiasts who like to target-shoot for enjoyment. Some feel some nationalistic pull to defend against Germany^H^HRussia^H^HChina^H^HNorth Korea^H^H or whoever is the latest poster child threat to the American Way. And some think that from the very beginning of America, there has been one constant threat--the one threat the founders new first-hand and the reason for the right to bear arms.

It seems like terrorism to actually say it, but for some the main reason to bear arms is to be able to rebel against tyranny--foreign and especially domestic. In other words, it's important for people to be able to occupy a wildlife refuge and "take it back" from the government. Taken to the extreme, this right is for the express purpose to allow civilians to kill policemen and military personnel in a pitched battle. It's not really about hunting or defense against home invasion. It's about an armed citizenry to keep the government in check.

That's a part of "gun culture" with which the author may not be able to relate. That's very scary to a lot of people. And to some that thinking is no longer needed to keep people safe in the modern world. But to some, it's absolutely vital to the preservation of the Constitution.

You may not agree with it. The author of this article may not agree with it either. But it just goes to show that there is not one true gun culture. There are different reasons to oppose guns and different reasons to support them.
When stuff like this comes up it always seems so weird to me that with all the work that regulators put into this, why can't they at least scratch the surface of providing some specific examples? Of course there are legal documents, and maybe some "for dummies" versions written up about it.

But would it be so crazy for these regulators to hire someone who knows something about commonly used open source software and building web apps, to help provide a little bit of actionable technical advice? For instance, the majority of the internet is running on Apache or Nginx, why not have an official, EU-sponsored blog post explaining "here's how to set up a LAMP stack, or nginx and rails on a linux server, that complies with GDPR". Of course they can't cover every obscure language or framework, but it would be a starting point. And it would probably end up a lot cheaper than having to investigate and/or penalize people who didn't read the fine print of the law and/or didn't understand how it translates to actually running software.

Because despite how "simple" this post is saying these laws are, there still seems to be quite a bit of confusion on this thread, among smart developers, about questions like whether or not we're allowed to keep collecting webserver logs in the default format or not.

How it works out? Badly.

But you generally cannot build a system that intentionally does not have a certain capability and then successfully claim that laws don‘t apply to you, because your beautiful system does not accomodate them.
I think they have become a little bit better with letting the viewer know this. Cuban fought fairly publicly to retroactively void a term in the first few seasons of Shark Tank where even without an investment from the sharks ABC got a percentage of the company. They also call out pitches where the person has ridiculous terms and is obviously just trying to advertise for free.
Everyone would just change the description of their Patreon page to be "Support me so I can bake delicious cupcakes" or something else unrelated to the videos.

Q: would I still be able to keep session logs of user journeys through my site without explicit consent? If not, this seems like huge issue for ecommerce analytics. If I need to obtain explicit consent, that the user isn't required to provide to continue accessing the site then I don't see how these technologies are not basically dead in the EU.

Can you even legally do a customer churn analysis under the GDPR without explicit consent?

One of the biggest complaints I have about this is that the uses for data keep growing, and legally, you can't even test a hypothesis before getting consent, which you won't be able to do frequently because users hate being asked about anything.

My intuitive response to this law is to want to split my data into EU/non-EU parts, do all my work on the non-EU parts and hope that the insights gained there can be applied to EU users.

Keep in mind as well that no observation has yet distinguished between a neutron star and a black hole.

i.e. all those photos of super massive objects could be neutron stars, and we would not be able to tell the difference.

They are assumed to be black holes because of the mass, but if there is something in the law of physics that prevents black holes from forming we would not know.

We do not have a theory on quark degenerative pressure for example, which could possibly exert enough pressure to prevent black holes from forming (you would get quark stars instead, with no event horizon).

There are also time dilation issues that might make black holes impossible.

I'm not a huge fan of WordPress mainly because of the security issues like the others have mentioned.

I've used it a little over a year ago and found things rather unintuitive when it came to setting up plugins. Not sure if it's gotten any better though. But, if you say it's practical, I'll give it another look and see if suits my needs. Thank you!
Sorry for the confusion, on the worst single day of smog I observed in Pasadena during the early 80s, the visibility was about as bad some 5-10 days I have observed in Beijing and multiple other cities in the last 2-3 years. It's not getting better, and it is so much worse than it was 15 years ago!

I thought it was getting better in China this year... I really did, but then winter came and you could barely see across the street at midday. Southern California meanwhile went from months of missing mountains to a day or two here and there during the summer over the course of 10 years as catalytic converters became standard.

Some things about English are easier than other languages, but it’s spelling is uniquely complicated. There are roughly 55 phonemes in English and 1500 distinct spellings for them. In most languages the ratio is closer to 1:2, not 1:30.

Phonetic writing could increase ambiguity but in many cases will not because:

(a) Many of the weird redundant spellings only show up in multi-syllabic words that are quite distinctive, as for example ti for ʃ in caution.

(b) People often can tell apart many shorter homophones, which are frequently mis-spelled by being substituted for each other: road/rode, or their/they’re/there. The fact they are frequently substituted for one another is a clue to the degree which context disambiguates them.

> It closed a loophole where Prop 13 (and other tax-restricting props) could be circumvented by introducing new taxes with slightly different names.

No, property taxes are local. Prop 13 tied the hands of the state government. Prop 218 then applied the same shackles to local governments, which ensured that California would see the wave of municipal bankruptcies during the great recession and which prevented local governments from switching to progressive water usage rates during the drought.

> through well-defined legislative routes versus political backrooms.

The only feasible route that is allowed is ballot initiative, which is why we're in this mess. Every other state and local government in the country has a representative democracy that allows its representatives to manage state taxes and budget.
