I mean, in order to define dimension, we have to know that bases exist (and all have the same cardinality). Which means that before I can use the notion of "dimension", I have to know about bases.

I mean I suppose you could just restrict the definition of dimension to vector spaces that have bases, and then you wouldn't have to. I guess that's what you're implicitly suggesting, that dimension would just not apply to vector spaces that don't have bases. That would make sense. But I'm used to thinking of dimension as, well, a function of vector spaces, not a partial function, so as I was thinking of it, you have to prove they all have bases before you can use it!
Is this the business side asking?
They're implicitly giving you product guidance here.

I'm also in the DS/ML space, and there is an absolute dearth of explainability in our models. It's atrocious given the decision that are based on these models to not be able to explain why they come up with what they did.

Get back to them and tell them you'll add explainability to your models. Even if it's just something simple like LIME (vary each input to a model, measure the change it produces - works for any model).

Yeah, the lacklustre rewards is definitely one of my pet peeves with it too. That and the foreign transaction fee, which killed the prospect of using it for shady foreign websites.

Also, one thing that Privacy gets right that Final didn't was the UX around virtual card generation. Privacy had browser extensions that let you generate new cards and autofill them on just about any website. Final never did, and that made making online purchases with a one-time Final virtual card a huge chore (though still less so than using a regular physical credit card).

If someone makes a Final clone that has 2% flat cashback, no foreign transaction fees, and a browser extension, I could totally see myself putting all of my purchases on it by default without a second thought.
Btw, do you have any engineers capable of working to upgrade the platform to use SegWit? I find it weird that Brian advertises open positions like there's nobody there capable of doing it.
Looks very promising! For those that don't want to click on the video (uploaded today), I've copied the description below:

"In this video Laolu (co-founder of Lightning Labs) demonstrates a multi-hop payment on Bitcoin's mainnet which travels across the 3 major Lightning implementations. In the demo Laolu (a.k.a roasbeef) sends a payment from our Lightning desktop app (https://github.com/lightninglabs/ligh...) to Starblocks, a coffee payment demo."

"This payment marks the first multi-hop, cross-implementation payment on Bitcoin's mainnet. All transaction performed in the video were performed completely off-chain, instantly, and with virtually zero fees. Lightning allows instant, low-fee payments on Bitcoin, enabling the system to scale further for the next wave of adoption. Additionally, Lightning unlocks a new class of use cases for Bitcoin enabled by the ability to instantly send low-fee payments on the system."

As I learned from my wife's first pregnancy -- you get bills from 12 different parties with vague names like Northern New York State Physicians Group LLC, which in aggregate are way over the co-pay limit. Try calling one, you cant reach them. Most are probably legitimate, but clearly they are incorrect in aggregate. We hired a billing consultant to reconcile all the bills, I imagine most people give up and either pay them all or just let it all go to collection.
And a bank run can’t occur in a 120B market? Or commodities worth 120B can’t be shorted? What?
My high school got a PDP-11/34 when I was a sophomore (class of '82), and offered a one-week intro that summer to all interested students. I was hooked, and wound up taking programming courses in junior and senior years (BASIC as a junior, COBOL as a senior). We were running RSTS/E, with BASIC-PLUS and WATBOL. WATFOR was also available, but none of my courses used it.

TECO scared me away; all I ever learned was how to load and run VTEDIT, if I were lucky enough to get one of the few VT100s. Unfortunately, most of the terminals were Visual 200s which frequently broke down and only emulated VT52.

Noting my interest, my dad went out and bought an Apple II+, and mostly by keying in program listings I taught myself 6502 assembler. A Heathkit H-11 (an LSI-11 system in kit form) would have really rocked, but I had a lot of fun with the Apple just the same.
It's the first in a new asset class that provides things that never existed before, mainly being the ability to quickly transact value over great geographic distances and national borders with zero interference from third parties. The value of that is extremely underestimated by most people, and shouldn't be so hard to grasp. Analogous examples are the Internet and Google, which provided very straightforward and simple value propositions that most people did not get, could not predict, and decried until they actually grew to enormous and important positions in society. Cryptocurrency is very possibly in the same vein, making valuations like this seem less absurd.

I wish I had the time and motivation to go back over the last 6 years and create a timeline of people making the same tired statements as yourself. The same types of statements were made when it hit 10 dollars.
Serious, this. There is no recourse for recover in the event of securities fraud.
I don't think it's underrated; it's that it's hard to write.

You almost go full-circle. You start off writing highly procedural code (with too much branching), join the GOF-all-the-things religion and eventually revert to highly procedural code (more specifically "algorithmic code" or "functional code").

As an example, many years ago I wrote a dependency resolver. It needed to find cycles (as we had some rules that could resolve those cycles) in order to make changes in the correct order. At the time I was a junior developer in that problem space. My solution consisted of an O(scary) algorithm; consisting of classes, patterns and all the good things that make your code "simple" and "understandable" (it was not). Customers eventually threw graphs with a few million edges at it and we needed a new solution. I have no idea how I happened upon Tarjan's Strongly Connected Components Algorithm but some hundreds of lines of code was replaced with dozens. Minutes turned into milliseconds.

Here's the thing about simplicity: even though the code was simple, even I (as the author) didn't understand it at the time - I trusted the guy with the PHD. Many years later I finally understand how it works. It is an incredible masterwork of simplicity but as it turns out something that is simple is not always understandable.

Simplicity probably has a simple definition in the dictionary, but in practice it can be quite complex to make something simple. So you can't just say "make your code simple" because it's really hard to do that.
Haha they made you a lot of money by waiting this long!
Actually there was circle they were very similar to coinbase, I used them for a while. They decided to get out of Bitcoin for some reason and I have no idea why.
I agreed with your first sentence, but then was confused by sentences 2 and 3. That's exactly the scene I recognize from 2011 until now.
> almost by definition depending on how exactly you define dimension

What definition of _dimension_ is there that does not rely upon the existence of a base?

> Ripple are more focused on positioning XRP as a settlement layer for banks and big FX houses rather than as a day to day currency

Ripple the company is focused on that because they don't want to spread themselves too thin, however the currency itself can absolutely be used as a day-to-day currency [1]. Its incredibly fast (transfers happen in literally 2 or 3 seconds), and the transaction cost is incredibly cheap [2] (currently about $0.0003).

this is an opinion piece.
Feels like one of those particular/general cases. In particular, few people routinely code in assembler any more. I imagine you can do degree-level courses in "computing" which don't even go there. I know you can do courses with no VLSI or microelectronics, both of which were required subjects on many courses at one point.

So yes, in particular terms, we don't do things which machines (programming language compilers, VHDL->VLSI compilers) can do better.

But "general" case, no. we still "do" these things. They're just specialized.

So particular case, will everyone write code in imperative languages? No. But general-case, yes, people will still write programs.

There's basically nothing to see here. One or two minor bug fixes, a few cleanups, and a new build system replacing one that already worked fine.

In my experience replacing the build system and doing nothing else is usually a good indicator for a project that will be soon abandoned. If that's the first priority it means there's no real drive to implement anything new.

Wow this is tragic. I'm guessing it serves whatever market that Springer has identified. But I'm not sure that's such a good thing: at some point the more details you add to the exposition the less clear it becomes. The reader needs to stand on their own two feet, especially in mathematics. Some people seem to be good at memorizing endless rules and details, so I can see this serving those people. But those are the people that can just follow the "determinants path" that this book was originally meant to disavow. Sigh.

Yeah, F# is kind of problematic since you aren't forced to use F# to typefully use F# libraries. Things would be a lot better in a language like Standard ML, where you can either use a library correctly (assuming it exposes the right interfaces) or not use it at all. Hooray for abstraction!
It's not about fairness, it's about pragmatics. We have higher taxes on corporations (actual taxes, not just paper rates) than countries like Canada, Germany, France, the U.K., and Switzerland. France's corporate tax burden is half of ours. Meanwhile, Europe has over the last 20-30 years dramatically liberalized its economies, and as a result is a pretty compelling place to do business.

It's one thing to have higher tax rates than some desperate third-world tax haven. It's another to have higher rates than highly developed countries with strong business environments (i.e. our competitors on the international stage). Many companies are happily shipping jobs over to the U.K., Canada, etc., to lower their tax burden.
I never said I consider bitcoin safer than US Treasuries. I just said I wouldn't consider US securities to be a safe bet and that even US Treasuries might be considered riskier than bitcoin.

Every asset has some degree of risk. And even something that might be considered somewhat risky might even reduce the risk of a portfolio through diversification if its risk doesn't correlate significatnly with the other assets.

Safer than it was but your take also shows that it is just starting, people are still deterred by the risk. As it becomes safer the risk goes down and more enter. It is still the early days of crypto currencies for this reason.

The fear you have is real, but it is slowly getting better and with that more will enter. Just like investing in early companies, it is riskier now, but as it becomes safer, those risk takers are rewarded.

Funds were lost in mtgox, btc-e, many others and there is fraud abound (pre-SEC times or early), but coinbase and the coins they offer are currently safer than it was. As more players enter it will be safer still.
It's safe if you keep your money in coinbase.

Apparently they will list on 18 Dec on CME, and 10 Dec on CBOE.

I get the feeling that there will be a fair bit of selling pressure as a result. That's usually the case on lockup expiries and it would make sense for the initiation of a volatile instrument that wasn't previously shortable on a listed basis.

I wonder how hedging transactions will affect the mechanics of the bitcoin market.
Brian Armstrong has quite the history of being on the wrong side of every argument to do with safe and scalable crypto implementation. He has been a champion of centralization and attacks on bitcoin governance. He was a vocal proponent of four out of the five failed fork attempts of bitcoin over the past couple of years. He, and coinbase investors, are very lucky they had people like Charlie Lee managing the technical parts of coinbase.
Not in the HN tax brackets they don't.
Of course -- but they didn't plan to run out of money. So what didn't go according to plan?
That's not how it works. You create two wallets with the same initial 24 words and a different 25th word, and put a small amount of money in the second one. If an attacker has the first twenty four words and tries to beat the 25th out of you, you give them the word that unlocks the fake wallet. They have no way of determining if you have more than one wallet, or how many you created. The only way they could tell it was a decoy would be if they had some other way of knowing the approximate value of your wallet.

I think it's subtly different in a very important way: there are a zillion developers doing almost the same thing everyday with almost the same mistakes.

The devil is in the almost. That's where the inability to trivially design a framework to cover all those cases comes in. That's the little subtle differences in business logic, that turn into different flavors of tech debt, that keep people in a job for a long time.

Tools and abstractions will improve, but here's the flip side: have you ever worked on a project where you consistently delivered 100% of what the stakeholders asked for, on time, with no negotiation or compromise needed? I haven't, so I think the more we can deliver, the more that will be asked, for quite a while.

Going out on a limb but I think OP probably meant that:

1) They take account verification seriously and leverage best practices around 2-factor auth etc even going so far as suggesting you NOT use simplified solutions like authy.

2) Your "hot wallet" balance is insured from internal breach / external hacking / etc. Good to note it's not insured from somebody stealing your account credentials from you directly.

3) They store 98% of their total crypto balance offline with a physical system designed to minimize losses or attack vectors.

Indian startups beg the government for 'preferential treatment'
Ask HN: Why would Facebook/Oculus not just give away/discount VR headsets?
Facebook needs a large user base for VR to get going.

And given that they are prepared to spend billions buying Oculus, why would they not just spend the money to give away the headsets, or maybe massively discount them down to $10 each for example?

The new Oculus Go standalone VR headset is said to be only $200. At this price Facebook could spend $500,000,000 and get a user base of 2.5 million.

I would have thought getting this initial user base is the important part of the equation.

So why don't they do it.... give away the headsets?
