Pooyan @pooyan.xyz · 01/10/2026This slide was in a talk about the same optics, conveniently named the Bigger Beamsplitter. LOL! A few days ago I stumbled across the same box at LIGO Livingston and instantaneously recognized it as the one behind the random guy's pickup truck. (I was vacuum cleaning the floor. More LOL!) 010 1

Pooyan @pooyan.xyz · 06/08/2026And yet my department at UC Riverside is trying it's best to make things as nerve-racking as possible for the first-year graduate students. The argument being that it's the only way we can keep the program "rigorous". 110 1

Pooyan @pooyan.xyz · 29/07/2026Emojis are fascinating creatures. Unfortunately, there aren't many Science emojis out there. (especially Astronomy ones) UNICODE consortium is the body that manages the standard emoji list. Proposals for addition of new ones could be submitted by the public. Maybe a few of us should submit one. 110 1
Pooyan @pooyan.xyz · 29/07/2026Again, now assume you handing your passport with an expired visa to the TSA at the airport, and they handing it to the ICE agent standing next to them. 000 0
Pooyan @pooyan.xyz · 29/07/2026As a result of this, California DMV cancelled driving licensees of 300 thousand people a few months ago, and dared calling it only affecting a limited number of costumers. In my case, it took me months to figure out what was the issue, and I never got my California DL back. 100 1
Pooyan @pooyan.xyz · 29/07/2026Another frustration comes from the law-maker not understanding the nuance. For example, in the Real ID Act of 2005, one of the requirements to show that you are in the country legally is a "valid unexpired visa". Either the law-maker didn't know what that means, or in this case probably didn't care. 100 1
Pooyan @pooyan.xyz · 29/07/2026The problem arises when the person working at the bank or the DMV doesn't know the difference, and denies service to someone with expired visa. The bank is okay, you can always try explaining the nuance, or going to a different branch. ICE agent with a gun and quota? Good luck! 100 1
Pooyan @pooyan.xyz · 29/07/2026The expiration of visa means nothing, if you are already in the country. You won't be using the visa in the country. The legality and the duration of the stay is tied to the status, not the visa. In my case, for example, the visa was single-entry. It expired as soon as I entered the country. 100 1
Pooyan @pooyan.xyz · 29/07/2026After you enter, the legality of your stay is not determined by the visa, but by the 'status'. It's your status that determines if your stay is legal or not, or for how long you are permitted to stay. 100 1
Pooyan @pooyan.xyz · 29/07/2026In the US, visa is the document that tells the border agent that a US embassy or consulate has determined that you can enter the country. (The fact that visa doesn't guarantee entry is a different story) The port of entry is the only place that you would need the visa for. 100 1
Pooyan @pooyan.xyz · 29/07/2026This reminded me to talk about the difference between a visa and status in the US immigration laws, and how what we regularly refer to as a visa, is in fact usually not a visa. Imagine how disastrous it could be if you need to explain this nuance to a bigoted ICE agent with a gun aimed at your face. 100 1

Pooyan @pooyan.xyz · 08/07/2026Star Trek has been the faithful companion of my depressed periods in the past few years, so here are my unsolicited controversial opinions: Best ST series IMO is DS9.

Pooyan @pooyan.xyz · 05/07/2026If a viable free alternative doesn't exist for a tool, which is very improbable, then we do have a responsibility to create the alternative.

Pooyan @pooyan.xyz · 05/07/2026Any material for the public must be accessible by the public. Public offices should have a mandate to use free and open-source softwares and standards. The public sector shouldn't be a funnel for the tax money to go to the for-profit corporations. 2142 14
Pooyan @pooyan.xyz · 05/07/2026On top of all the brilliant things people have said in the comments here, it is very absurd that MS products are the standard in our governmental and public services. (also administrative work in academia) 1298 29
