> A month or two ago, sure - TX congestion had driven up fees to ridiculous levels. Now that the congestion has cleared, I can once again send hundreds of thousands of USD across the world for less than a dollar.

Congestion has only cleared because the transaction volume has fallen to a two-year low:

The bubble is deflating, in case you haven't noticed.

> It's like if the NYSE only allowed you to cash out in scrip. I understand how this benefits them, but how does it benefit me?

It doesn't benefit you, as you're left holding a bag of useless scrip if there's a big crash.

Which is precisely why tether is such a cause for concern. Well, except for crypto fanatics that call anything perceived as negative as baseless FUD.

Not very surprised, no. It was just a matter of time until it became public:

GenericsMotors··on Robinhood Crypto – Invest in Bitcoin and other cryptocurrencies
Correct that it's not entirely luck, at the moment its price is being propped up by Bitfinex. Whenever BTC value starts to dip below 10K USD, they just print more Tethers (USDT) and start buying up coins at above market price...and there's a new upswing.

It's not at all sustainable, though.

GenericsMotors··on Bitcoin Fall Extends to 25% as Fears of Crackdown Linger
> I always think there will only ever be 21 million bitcoins in existence ever. Ever.

So what? If I launch a cryptocurrency that will only ever mine 21 coins, how does that make it magically orders of magnitude more valuable than bitcoin just because it's more scarce.

> Not sure why you and the other person mentioning lightning have been downvoted.

Because it's a ridiculous proposition. Just opening and closing a channel will require a transaction on-chain, with the accompanying fees.

And if someone sends you coins, you can only spend them if there's a route to whoever you want to pay, otherwise you have to close the channel....and again pay the damn fee.

Lastly: it's not even a network. A network implies that there are multiple connected nodes, and AFAIK the number of merchants using LN in production is exactly zero.

> The fact that the blockchain _is_ fully stored and verified by a number of distributed parties, and that you do have the ability of downloading and verifying if you want or need to, is enough to keep the system honest.

How will you download and verify the chain when it hits double digit TBs?

How about 10 years from now, when the storage requirements are an order of magnitude greater than that? The rate of growth is far outstripping consumer storage device capacity...

* sad trombone *

They're obviously not the most secure, as the Project Zero research shows. The whole press release has to be one of the most dismissive and snobbish PR pieces I've seen from a large corp.

Firefox installs crapware addons without user permissions and signs them up to participate in "studies"? Shhhhh...it probably only an innocent bug, nothing to see here, move along now.

Garbage blogpost.

I dislike the bitcoin and cryptocurrency industry & communities in general, but this is just ridiculous.

GenericsMotors··on What MongoDB got right (2015)
It's not moot: Dapper doesn't auto-generate the query for you, it's just a thin layer over .NET's SqlClient to reduce boilerplate of converting to and from C# objects.

You still have to write your SQL statements, and in your example you'd still be able to refer to your array by name:

    select SomethingID where AnotherThing in @yourNamedArrayParameter
More here: https://github.com/StackExchange/Dapper#list-support

If you're not using Dapper just use a user-defined table type to hold your data and join on it instead of using WHERE IN.

GenericsMotors··on What MongoDB got right (2015)
Indeed! They are usually my preferred why of interacting with the DB when the queries are complex or hold a good amount of logic.

Add user-defined table types used as parameters and you've got a good way to pass batches of data too.

GenericsMotors··on What MongoDB got right (2015)
> What about `WHERE foo IN (?,?,?)`.

This is can be automatically handled if your ORM supports it; even a micro-ORM like Dapper does.

Otherwise my go-to solution for this if it isn't supported is to pass the collection as a user-defined table type, filled with the values. you can either use WHERE IN or join on this table variable.

EDIT: my perspective on this if from working with SQL Server and .NET. I don't know enough about Python or PHP development to comment on those.

GenericsMotors··on What MongoDB got right (2015)
> Querying SQL data involves constructing strings, and then – if you want to avoid SQL injection – successfully lining up placeholders between your pile of strings and your programming language. If you want to insert data, you’ll probably end up constructing the string (?,?,?,?,?,?,?,?) and counting arguments very carefully.

Uhm what?

At least in .NET+SQL Server land you can give your SQL queries named parameters. If there's a mismatch you'll get an exception saying so...

Perhaps this is a problem in some other stack (PHP?)

They get zero points for this.

It pretty much reads as "Retard"DB in Portuguese, Spanish, and IIRC German.
