Man I really hope other people get this one, because it is awesome.


Perhaps you can explain the joke, and why it's funny for you..? I do enjoy jokexplainings, not as much as a joke I do understand, but even more than jokes that I didn't get.. ;)


Huh? What do you mean unavailable? I see it just fine.


I can confirm - I saw "this tweet is unavailable" message or something similarly worded on first click too. Reloading fixed that.


Is there a sane web Notification Center yet? Nope. Sigh.


Can we just get a decent unified Notification Center, please? Notifications in GitLab are painful, just copy how GitHub does it and stop trying to make it so complicated.


Not being a gitlab user I'm surprised its notification are worse than github's, because it's not like github's notifications are any good. Between the comment notifications which don't link you anywhere half the time (possibly on inline comments? I never remember) and the update notifications which give you a completely empty diff on a push force, it only serves to signal that something happened on this thing you don't even care about.


All GitLab notifications are via email unless someone explicitly @s you. Furthermore, there is no api to notification. Basically, unless you monitor email, you don’t get notifications. It’s horrible.


Instead of watching general notifications I just subscribed to specific RSS feeds for issues, mr, etc and use RSS as my notification engine.


Wow that does sound nasty indeed.


Ran a business that started on stitch. What a painful piece of software that is. We had a heavily custom integration to their api and very high order volume. Moved to NetSuite, built many a customization and integration. NetSuite is great, but expensive and you will find the developer experience painful. As an ERP without investing heavily in customization it does a great job.


SuiteScript has improved, there's now intellij plugins and they've recently upgraded the supported JS version which runs on Graal VM. It's still a little clunky but that's just ERP for you.

I'm seeing some customers pay around 50 - 80k AUD per year on 1 - 2 year terms at the moment. What would you consider expensive?


Blosc is an outstanding project. I have used it with great success in finance and general data science in production with very large total datasets (one custom binary format and one leveraging protobufs).

It really shines first and foremost as a meta compressor, giving the developer a clean block based API. Once integrated (which really is quite easy) you can experiment easy with different compressors and preconditioners to see what works best with your dataset. These things can be changed at runtime and give you great flexibility.

Francesc has been advancing blosc consistently with a steady vision for years and years. It is one of the most underrated tools around IMO.


Here’s an idea: don’t project your values or idea of worth on what other people choose to do with their life. You’re not as righteous as you may think you are, I guarantee it.


> don’t project your values or idea of worth on what other people choose to do with their life.

Unless you're a moral relativist, why shouldn't I do this? I find this entire attitude baffling.

If you went around assassinating people to make a living, I think I would be fine in saying that you're an asshole, no?

That's pure gold! I'm putting that one in my notes!

But to play devil's advocate: Well, if you go empirical on this, then what the heck else is the Internet for, aside from porn!?


Not sure if it's intentional, but that's an interesting twist to "this statement is false".


For soccer it’s trivial to remove the aerial aspect from the youth game, in fact they’ve already done it. No headers, no throw ins, etc. Doing so doesn’t do much to change the game at a youth level.

Football on the other hand... it’s pretty much impossible to take the CTE risk away without ending up with another sport (rugby, Aussie rules, whatever).

IMO the long term viability of US football is not good.


I would bet also that an effective soccer helmet is at least feasible.


This is how any reasonable institution not 100% focused on cryptocurrencies will gain cryptocurrency exposure. The big reason is they are backed by CME clearing and settlement. It helps to significantly reduce the counter-party risk associated with other venues.


Note that storing bitcoin properly comes with no counterparty risk whatsoever. That's like 50% of the entire point of bitcoin!


You are correct, but I feel compelled to point out that the average person should be hesitant to hold bitcoin personally.

Crypto is hard to get write, and people suck at key management.

If you're going to store your own bitcoin, please do several 'test runs' depositing tiny amounts and practicing retrieving it. Understand potential attack vectors. Too many stories of "I forgot the pin i used to encrypt my private key" or "I saved my private key in gmail and lost all my bitcoin when my email got hacked" or "I used a malicious wallet software and it stole all my coins".


Instead you have lost password risk.


And hacking risk. And insiders stealing them and claiming they've been hacked risk. And similar.


Well, the fact that the majority of the mining pool runs out of China certainly represents a counterparty risk. I'm not sure why folks regularly ignore the 51% issue.


While there is certainly some amount of quantifiable risk given how centralized mining is in China, each individual mining actor is still incentivised not to participate in a 51% double spend attack as the value of bitcoin would rapidly fall towards zero if a double spend attack ever did occur, making their ASIC investments unprofitable in a hurry.


I don't know. It's like nukes. They say, no one would use them, because that would let the cat out of the box. But... on the other hand, what would happen if someone used only a single nuke? Could we get to the circumstance that Bitcoin was "too large to fail" and a someone could get away with a double spend?


I would like to know the same, but I do have a theory. What will they do? If they start making invalid decisions, the rest of the network will fork. It won't be pretty, but btc will survive... Or is there a better explanation of risks involved?


51% means you can double spend. it doesn't necessarily mean you can steal money


The counterparty risk is not in the storage, but in the exchange. You always expose yourself to counterparty risk when you exchange currencies (even crypto ones).


No counterparty risk on decentralised exchanges


Decentralised exchanges just have terrible spreads and front-running instead.

Also, I don't think a decentralised exchange works for USD. Any token backed by USD has counterparty risk.


Spreads on EtherDelta (which is widely used) are good, but it's only for ERC20 tokens. The UX is awful and it can be slow because of Etherium scaling issues.

You're right about any token pegged to fiat (like USDT) having counterparty risk. The company offering it, the bank they keep their funds in, and the country's legislation. I wonder if something decentralised will emerge that will effectively minimise those risks.


No, they aren't. There are all sorts of futures contracts, and they are all derivatives and none are indexes themselves. There are equity index futures, single stock futures, foreign exchange futures, treasury futures, etc. Cash settlement vs the ability to take settlement in the physical underlying is where you might be getting confused, but they're all futures nonetheless.


Why do futures exist for something that can be settled in 30 minutes?


Suppose someone will pay you one bitcoin next week, as per some private agreement.

For this discussion, let's entirely ignore credit risk (the risk this person doesn't pay) but consider market risk.

Like it or not, you carry the risk of bitcoin fluctuations. You might be comfortable receiving $6400 for your bitcoin next week. But bitcoin is volatile. Maybe bitcoin jumps to $8000. But maybe it drops to $4000.

If you're comfortable giving up the upside, for a chance to prevent that downside, this bitcoin future is for you.

You enter a future contract where you agree to sell one bitcoin in one week at a price of $6400 (if that's the going one week forward rate).

In one week, your person pays you the agreed bitcoin, which you then sell to the exchange and receive your $6400.

Meanwhile, for that week you can sleep at night knowing that if the bitcoin market crashes, you still get your $6400. And if the market rallies to a higher price, well missing out on that rally was the cost of being able to sleep at night.

This is what commodity futures were originally used for, eg farmers agreeing to sell their stocks at agreed rates without worrying about market fluctuations.

Companies do this too, eg hedging their cost of fuel to a known quantity in line with expected consumption.


For one thing, bitcoin miners would love to short the future price of bitcoin. They're spending dollars now to buy mining rigs, which make bitcoin later. They're exposed to the future price of BTC for whether or not this is profitable. With a short futures position on BTC, it turns uncertain profit into more certain profit.


Because then money and commodity never actually have to exchange hands. If you trust the CME to guarantee all parts of the transaction, and if you have no use for the commodity beyond speculation, then why part with all that money and move around all those bitcoins?


With a future you can create negative exposure, aka being short. It's a lot more straightforward than finding borrow for it and arranging to pay interest and returning it after you're done.


> Why do futures exist for something that can be settled in 30 minutes?

Because money.

Or more specifically, someone is willing to sell these futures to someone who is willing to buy them.
