Very nice! What's the data source for the greeks? Are you computing those yourself?

I'm using Tradier API for market data. Greeks included. I don't do any calculations.

Oh, please, cry me a river. There's always a law to bomb another country, spy on the RoW, hack ally infrastructure, renege international treaties or put on some tariffs on imports from friendly countries, but somehow a minor contractual clause grinds to a halt export of vital medicine supplies during a pandemic.

There’s a distinction to point out here. US courts enforce contract law, but the international political system is anarchic. Contractual breach cases have a venue willing to hear their case, your examples of actions taken against nation-states by the US government do not.

How proficient do you have to be in Redis to have fun in such a hackathon? I use Redis mostly in combination with Python Celery.

That mostly depends on your definition of "fun."

Assuming by "fun," you actually mean "competitive," then it depends on who else enters, I suppose, but the more proficient you are, the better.

As far as I remember, it's a first time there are separate devrooms for Apache OpenOffice and LibreOffice. It's been 10 years now, is it me or it feels like a waste of efforts ?

OpenOffice is a waste of efforts, sure. It's not really a problem though as there are barely any efforts at all.

>That's ridiculous, my wife makes great money using OpenOffice to create and publish digital downloads for teachers.

What parent means is OpenOffice is barely maintained (or no effort is put), not that it's worthless.

They also imply that LibreOffice is where the action is, and is better maintained with a bigger community.

I don't follow the projects to know if that's the case, but that's what the parent seems to mean, not that OpenOffice is not usable.

Thanks for clarifying.

If you voted YES and were able to choose among the available (Western) vaccines, BioNTech/Pfizer, Moderna or Oxford/AstraZeneca, which one would you take? Does it matter for you?

“ Russia approved the vaccine after trying it on several dozen subjects in a non-blind study and ahead of Phase 3 trials, which are key to establish its safety and efficacy, drawing skepticism from the international community and accusations it could have jumped the gun for political gains.”

It's not clear what you are quoting, but there are vaccines besides the russian one. For example there is also the Chinese CoronaVac.

I think there are completely reasonable reasons for people to consider these vaccines as well. Some have larger phase III trials, and some are tested in different demographics. for example, Arabs might be more comfortable with trials that were run with predominantly arab participants.

So many invasive species beside mosquitoes. Box tree moths have now invaded huge chunks of Western Europe. Depending on the year, they can be abundant and have done some serious damage to green areas.

Without decent understanding of how options work, even iron condors can turn bad. You are writing options, so you're still running assignment risk or pin risk. It's mostly benign if you know what you are doing but can be a brutal lesson if you just clicked because you think "it's staying the same".

This will be killed or severely hampered by antitrust agencies. Definitely by the EU, maybe the US as well if there's anyone decent left there.

Antitrust nowadays is just a buzzword politicians throw around every couple years in reference to household names like FAANG in order to get reelected. Unless your average grandma knows the name Nvidia, don't count on those in power to even pretend to do something about this.

Why? From where I sit there will still be plenty of (or at least no less) competition in the CPU/GPU space--especially considering the fact that ARM itself is not a semiconductor manufacturer.

Why definitely? What if Nvidia is looking to get out of producing GPU hardware and move to an ARM model?

AMD ATI deal went through , if this got blocked , isn’t it antitrust other way around ? You are not letting Nvidia compete with AMD?

I'm not sure about the particular component but Xetra/Eurex indeed went down in April. Same pattern as today: it went down around the opening hours and got fixed around lunch time. They have some structural problems that have likely been left unsolved.

Options can probably first be seen as a form of insurance - you pay a small price to protect yourself against upward/downward movements. It's of course taken to the next level by r/WSB as a tool for leveraged gambling.
