And then you remember that as part of the passenger safety case for driverless taxis, there will necessarily be cameras and microphones and the ability to lock the doors and redirect the taxi to the nearest hospital or police station, right?

When we were building the Heathrow Pod[1] -- which is effectively an autonomous taxi system -- this was an objection that people raised all the time. In practice, it took approximately zero instances of bad passenger behaviour for people to catch onto the fact that the interior of an autonomous vehicle that can deliver you non-stop to airport security is really the last place on Earth that you'd want to engage in anti-social behaviour.

Are we talking about Bitcoin or all crypto?
Bitcoin and many other cryptocurrencies are fiat currencies, nothing more. Bitcoin's value is dependent not on underlying fundamentals, but rather on supply and demand. Its supply is limited and will be fixed, but its demand is based on on its perceived usefulness, either for storing value or making purchases (maybe other things?). Until we see that it is useful for these things, we should assume its fundamental value is zero.
There is nothing wrong with JWT, implementing them requires some thought so that you don't leak sensitive info as well as configuring your backend properly.

Large swaths of the internet love to hate on JWT but its a major feature in oauth2 and is in use all over the place as decentralized APIs have become more commonplace.

I was once told by a friend when exploring smart TVs:

"Let me lay some Harry Potter logic on you: 'never trust anything if you can't see where it keeps its brain'."

This is actually very good advice (I've probably got the quote wrong but I digress). You're going to encounter abandoned products everywhere in smart tech; I wound up buying a Roku box and a dumb TV instead. It's a good combination - Roku is popular enough that the apps/channels are kept up to date, and I never need to worry that my TV will lose its features in a few years. If the Roku box shuffles out of support, it's cheaper to replace that than the TV.

So the recommendation - don't bother with a smart TV unless you really need it to be all in one, and buy a smart add-on box instead.

Transmission: RPC session-id mechanism design flaw
For everyone saying that people are so used to clicking yes on dialog boxes without reading them: Then change that paradigm for different levels of importance. For example, for a test alert, use an automatic countdown that will activate the alert unless canceled within N seconds. The ramifications of a test alert going out accidentally are a lot lower than a real alert going out accidentally. For more serious alerts like this most recent ballistic missile one, turn the entire screen red, have “THIS IS NOT A TEST” header, with an explicit acceptance required to send the alert. Two people may mitigate this existing problem but it still doesn’t get to the root of the issue.

Same thing with your hammer analogy. Everything shouldn’t look like a nail then! A real alert should look like a nail. A real ballistic missile alert should look like a railroad spike (aka really big nail). Test alerts should look like a screw. Etc.
> Do not use JWTs, which are an increasingly (and somewhat inexplicably) popular cryptographic token that every working cryptography engineer I've spoken to hates passionately.

Can we get more intel behind why JWT is bad? I've always been told that as long as you explicitly check both the signature and that the signature algorithm type is what you expect, its fine. Libraries tend to make the mistake of not doing that second part for you, so implementations have to be aware of that.

The one concern I've always had is that even though they are stateless, most implementations end up making a db request to get info about the user anyway (i.e. their role and permissions), so the stateless advantage of JWT isn't as big as it is touted. You can embed that into the JWT, but then the token inevitably gets huge.

Were you around a few years back to see real estate values drop from $300K to $25K? I saw that. And we are talking about a physical property.

$25K is not zero, but it would be hard to distinguish the effective difference if you're leveraged $250K.

So, as with any investment, if you're spending monopoly money on cryptocurrencies, scoff away. But if your retirement depends on it...
An admirable goal. One of my pet peeves with lots of php code and extensions is the unending desire to make every bit of cold backwards compatible to some of the oldest versions of PHP.

There are some great, new cryptographic functions that have been implemented in PHP >= 5.5

Password_hash() and password_verify() are so simple, it's hard to mess up password hashing now. When I upgraded my projects to PHPa7, I replaced dozens of lines of code with those 2 functions alone.

But I have seen plenty of implementations of them that still fall back to old more convoluted and error prone methods when you are using some old version of PHP.

> When one guy has accumulated large sums of money by promising to invest it only on the basis of yield and then turns around and starts throwing that weight around, he's effectively overriding the collective judgement of many other people who can't cause as immediate an impact on any specific firm as he can.

By investing with an organization, individuals and institutions are authorizing that organization to make investment decisions on their behalf within the stated objectives and requirements of a given fund. In this case, Fink's thesis is that social responsibility will lead companies and consequently funds investing in those companies to outperform in the long run, which is in line with the firm's obligations as a fiduciary. If investors feel like this perspective isn't representative of their individual judgement, they can take their money elsewhere. If investors continue to invest with BlackRock, they're deferring to Fink's judgement on this issue and nothing is being "overridden".

Yup. AMZN traded at around $100 in 1999, then $12 just a few months later. Now if you believed in Amazon's business model and bought at that low you could have made about 120 times what you invested if you sold today.

For me I look at crypto the same way. Crypto's value is going to fluctuate over time, but I think that over the long term (5-10 years) it will become more stable and more valuable. A huge dip is a great time to buy.

It also helps to only buy crypto for fun and consider it akin to gambling :)
Crypto as a whole going to zero? It would only go to zero if there was zero utility. Whether or not the market is overvalued at the present, there's plenty of value there.
This is kind of confusing.

You don't have to commit to a big up-front effort. You can take an incremental approach and add type annotations as you need them.

Also, I'm not sure how adding type annotations results in over-engineered solutions. Types are just little sanity checks you spread around your code to help the compiler and linters to catch inconsistencies. You shouldn't have to re-engineer everything.

It's about transaction fees and computing power. The cost of powering the computers that verify transactions has to be covered.
I think the biggest irony is that the web allows for more adoption of long-tail movements than ever before, and Google has gotten significantly worse at turning these up. I assume this has something to do with the fact that information from the long tail is substantially less searched for than stuff within the normal bounds.

Google wants you to be mainstream now. If everyone thinks the same and wants the same things -- even if contextually as a member of one of a couple of hundred disparate "marketing cohort" categories -- it will be far easier to target advertising to you. It's in Google's interest for you to conform now. Be easy to categorize. Be easy to predict. So think the same as the members of your peer group, so they can sell hyper-targeted advertising to other corporations. (Have you noticed that social media tends to motivate you to conform?) Google has no use for the long tail anymore -- no use for quirky and inscrutable scenes and subcultures. Instead, it now has the cultural power to transform you (the product) into an even better product.

Yes but not accepting currency[0] or coins is different from not accepting USD. In the United States a creditor may choose to only accept certain forms of USD (ie. no $100 bills at some stores) but they still must accept USD in some form.

[0] It is obvious from your link that the Treasury intends "currency" to be interpreted as paper money, see this:

There is, however, no Federal statute mandating that a private business, a person or an organization must accept currency or coins as for payment for goods and/or services. Private businesses are free to develop their own policies on whether or not to accept cash unless there is a State law which says otherwise.

Comparing cryptocurrencies to actual companies isn't fair. A lot of companies that went bankrupt (aka worth $0) had assets. Those assets were worth something and were probably sold off and used to pay debtors.

What assets does a cryptocurrency have? What value is actually there?

> Are we talking about Bitcoin or all crypto?

Either. Spinning up a cryptocurrency may become as mundane as creating up a database, as silly (or illegal) as trying to market a Ponzi-based hedge fund, or simply a pedagogical tool for CS students.

There is nothing inherent to crypto that says it must hold value. Markets are moody.
These DB -> API tools show promise, until you want to do something outside the CRUD box like upload images or process payments.

Also, I've found it much harder to modify functionality because now your business logic is embedded in your DB which is harder to version than backend code.

In any event, if you want a GraphQL/DB API and don't want to pay for graph.cool, there's a great similar tool called PostGraphile: https://www.graphile.org/

You are fundamentally arguing that cryptocurrencies, all of them, will be gone? That like 30 years from now, there will be 0 things that are basically cryptocurrencies or something that replaced them?
Yes theres that, but BTC being overvalued doesn't explain the entire market dip that we are seeing now. However, it is consistent with Bitcoin's historical pattern:

Cool, thanks for the heads up. After wiki-ing around, it looks like current whitespace technology is hobbled by forcing the broadcast device to get permission from an FCC database in order to transmit. With that constraint, I am not surprised it hasn't taken off.
the idea that blockchains with utility are valued as a % of BTC is the real insanity. IMO the nature of crypto-panic will change quite a bit when fairx and other similar "every shitcoin is a cash market now" exchanges get off the ground.
The trend of 15-20% swings is well documented in Bitcoin history, no doubts about that. Crypto is a young economy in general, and it's been thrilling for me (on the outside, as I don't speculate or hold) to watch.

But I don't know. If you play with the zoom levels on price tracking sites, the $20k peak onward has been a pretty steady downward trend. BTC is down 20% over three days, down nearly 23% over a week. Is that par even for Bitcoin flash-crashes lately? Zoom out further to a month and the price is now down almost 40% at the time of this post.

We zoom out to six months, or a year, or two years, and we see astounding gains then – we are all aware of the blistering rise in price over 2017. But once it dipped after 20k, there were a lot of people who swore it would climb back. And then it dipped further, and further, and the collective memory of Bitcoin's humble recent history was lost in the cacophony of media blitzes and new customers entering the market.

I think the underlying worry for most people isn't the fact that the price goes up and down a lot... I think the worry really is that when growth stops will people still be interested? Can Bitcoin last forever if the price is e.g. <$5000/BTC?

This so much. Most men in tech can have a majority male discussion in any open community, due to their numbers. The amount of disparity from men towards leap in this thread is a prime example of why we women in tech seek to have discussions in more closed environments.

It has nothing to do with the issue rate of Bitcoin, frisbee-on-the-roof is potentially a real problem.

Say Bitcoin crashes down to $1 tomorrow, such that it's no longer profitable to mine. A bunch of miners go dark. What happens to the block time?

Now remember that difficulty readjusts every 2016 blocks. If there are now 1% as many miners, that means a 1000-minute blocktime and potentially up to 1400 days per adjustment period (average of 700).

In this situation, the only option would be a hardfork to bootstrap the network back to a live state, either by directly adjusting the difficulty or by readjusting more frequently and more aggressively.
I think a big problem is that people are conflating two kinds of value. One is the technical value of block chain and other distributed consensus algorithms. The other is the monetary value of block chain backed assets.

The latter could indeed crash without impacting the former. Advances in the former that solve cryptocurrency scaling problems could even cause the latter to crash by reducing artificial scarcity. Unlike gold there is no real objective scarcity here. It's just software.

"Bitcoin is a major innovation" and "Bitcoin is a bubble" can both be true.

BTW...

I'm waiting for someone to explain to me why this kind of appreciation in value is actually a desirable thing in a currency. It makes Bitcoin less useful.

> Are you saying the solution to "hey, women feel isolated in the tech industry" is to say "Well, let's figure out how to include men too"?

No, my solution to a sense of isolation is instead to find ways for women to no longer feel isolated within their field.

A great example with the other sex would be male nurses. Male nurses are definitely the minority in their field, yet they manage to not feel isolated overall. Even if they did, creating a male-nurse-only group wouldn't do a thing to correct the isolation-causing systems in their place of employment, and would only work to further separate male nurses from the majority by isolating them from the wider nursing community.

If women feel isolated, we should try to find out why and correct that instead of just sticking them with other isolated women.
