askmike··on It costs $436 to deploy a smartcontract on Ethereum
Once you deploy it it will be there, forever running on a decentralized immutable computation machine which is made up of nodes and miners all over the world being incentivized a certain way.

That kind of certainty has a beauty to it.

askmike··on China’s dodgy-debt double act

askmike··on The SEC has told us it wants to sue us over Lend. We don’t know why
And in crypto SEC is usually late to enforce. They only last week cracked down on the Bitconnect ponzi, which collapsed in January 2018 (that's an eternity in crypto)
askmike··on I'm the guy who bought 259684 BTC for under $3000 yesterday (2011)
There are many big trading firms trading billions a day willing to do the tether leg for you if you don't trust it yourself (they will take the risk), but a sale like this wouldn't happen at once anyway.

Most money in the orderbooks is from HFT MMs, if you start selling on Binance the bids on Huobi/OKEx/etc will dissappear, most likely before you can buy (correction: sell) all.

If you want to sell this much you really do not do it on screen (and definitely not at once). You get a big OTC desk to sell in tranches.

askmike··on Ever wondered how much data web giants generate? Grab says 1.7MB/user/day
> All that data is clearly valuable: Grab has also announced record profits.

What do they say about correlation and causation?

askmike··on Xi Jinping’s Capitalist Smackdown Sparks a $1T Reckoning
The utility is hard to measure, but brushing it off being valueless is subjective. It should be clear to you at this stage that not everyone agrees with you.
askmike··on Npm Audit: broken by design?
> Your source code is somehow compromised and attackers slip in rogue code to your production site.

Really at this point it's too late to do anything else, instead of trying to dos your dev machine he can instead do simpler things like delete your ssh key from the machine. But let's play along:

> The attackers also take advantage of several of these RegEx DoS vulnerabilities to prevent you from quickly fixing the problem. When you discover the issue, you’ll first see that your build machine is unresponsive

There is nothing any attacker can do with the static files on the server that will trigger and RegEx DoS in your local development. Aside from the fact that you wouldn't download whatever is on the server back to your machine, even if you did it would never trigger such a DoS since (in the examples in the link) these are modules related to running a dev version of a frontend project based on the raw source files.

Your scenario is only true when an attacker pwned both your production server and your laptop. A regex DoS is really the last thing you worry about at that stage.

askmike··on An unwanted update to your Google Account
What would they ask for? You can have residency in many countries.
askmike··on Massachusetts health notifications app installed without users’ knowledge
I think covid has shown that when the world is faced with a pandemic, not everyone agrees on what's common sense is in terms of how to respond as a society/government.

askmike··on Show HN: Ninjabot – A fast cryptocurrency bot implemented in Go
This looks super cool!

I would love to play around with this, but the docs are a little light at the moment (unless I missed them). Would definitely recommend pushing docs and content on how to build custom strats, extend the main framework with custom reporting or new exchanges.

It does Binance but it's unclear to me what product types (I'm assuming spot markets).

Things I recommend exploring: (high latency) arbitrage between derivs and spot (for example cash and carry arbitrage). Or super simple funding arb on coinmargined perps (short 1x into synthetic usd). Pure directional is hard, and besides that there is a ton of alpha in more market neutral stuff.

----

A long while back I created a framework with a lot of overlapping functionality called Gekko (not trying to shill, I haven't maintained it for years). It took what I learned from that experience and build a prop trading firm called Folkvang. Crypto has a sea of opportunities ready to seize and in a bull market like we've seen in the last few months there is plenty of fish for everyone (yes there is a free lunch, even for those without a decade of quant/HFT experience from wall street).

play, build and have fun - can easily grow into a career

askmike··on NSFW Server Designation
The point was that it looks very clear to be a restriction coming from Apple (which is why it's about restrictions specifically on the iOS platform and nowhere else). Apple is forcing these rules onto other apps like Discord.
askmike··on Substack's UI and 1Password temporarily cost me $2k
To counter this: if you happen to find yourself on the phishing domain facebo0k.com and you end up copying your password into that.. Browser extensions guard for this better than we can.
askmike··on Bitfinex, the Italian network behind the boss that makes Bitcoin tremble
Not sure this aged like you think it would:

> Or rather, what most people in the industry pretend doesn't exist, because they know it's a systemic risk and everyone's in way too deep at this point.

Are you referring to the NYAG here?

askmike··on Coinbase S-1
He might have been referring to the fees of coinbase pro, which also are pretty high fees (but orders of magnitude smaller than the coinbase retail app). Pretty high for crypto, insane for people coming from fx or other traditional markets.
askmike··on Bitfinex, the Italian network behind the boss that makes Bitcoin tremble
Your best case scenario is worse than what most people in the industry consider the truth..
askmike··on Bitfinex, the Italian network behind the boss that makes Bitcoin tremble
> but despite allegedly having several tens of billions of dollars in reserve, they refuse to do an audit.

They don't refuse this, instead they fail to find an auditor that people actually trust that wants to work on a big crypto project. They are very open about this.

The big problem about Tether is the amount of FUD and misinformation going around as common knowledge.

> I think the currently most plausible answer for how Tether works is

As someone who deals with Tether as well as all the big exchanges that run Tether markets, this is about as real as Alice in wonderland.

askmike··on Mt. Gox demise as told by a Bitcoin insider
There have been many bubbles before Mt Gox and there have been many after.

> Tether has been responsible for multiple bitcoin bubbles now

No one in the space actually believes this.

askmike··on The Rise and Fall of Bitcoin Billionaire Arthur Hayes
To make sure it actually does move near perfect tandem there is a new interest element that will incentivize the market to have the perp trade close to underlying.
askmike··on Mt. Gox demise as told by a Bitcoin insider
That's a very different subject, I don't see any overlap

askmike··on Safely open apps on your Mac
While everyone on HN (including me) is mad about the privacy implications of what's happening here - including how all this doesn't do much good for programmers dealing with all kinds of binaries updated daily, I quickly want to point out that I think this type of functionality is a great idea for most non technical users. Apple has always been at the forefront of extreme usability (kids using iPads, seniors sending iMessages) and the internet has a lot of toxic stuff that needs to be kept away from many non technical users (for my parents' computer, I rather have this ping home to Apple with hashes of apps they open than them being exposed to tons of malware). That said they really need to work on the privacy aspect..
askmike··on Ask HN: Is an ARM-based laptop a viable development machine for a Backend dev?
Yea personally I'm the same boat. But going out and buying a macbook with an intel processor also doesn't seem a great idea as that's definitely not the focus going forward.
askmike··on Ask HN: Is an ARM-based laptop a viable development machine for a Backend dev?
I don't think a blanket answer will apply to everyone here: which specific tools that YOU use won't support ARM (and until when exactly)? If some tools won't support it for a while, can you live without them? Do you need to run all these backend tools on your own machine?

I think many people are trying to figure these questions for them out right now, as there is very little information yet on ARM support from many tools.

askmike··on About iSH’s pending removal from the App Store
I'm sitting here as a developer, contemplating if my next phone should be an iPhone or Android - and this is the gist of what I think:

- If I buy an Apple I buy into this developer unfriendly ecosystem with a big gatekeeper.

- If I buy an Android I pay with all my privacy, on top of that Google is also a big bully to small app developers.

- Besides Google or Apple, what choices are there?

askmike··on Mall real estate company collected 5M images of shoppers
> Assuming that the 'biometric representation' is discarded by the system after guessing the age and gender.

It wasn't, it was stored in a third party database.

> Genuine question - if mall had deployed people whose job was to look at people to guess their gender, age and then jot it down in a notebook, then would it have been a problem?

I don't think these notes would ever come close to "a biometric representation of their face" which can tell you with certainty someone was there or not (when, what time, who they were with).
