Website updated

After spending several days, I significantly updated my website. Below is a list of main changes.

• Previously, there was a “Research” page that I created manually. But it was tedious to list all papers in a consistent style (like journal names in bold face, coauthors in italics, etc.) so I automated it.
• I omitted publication information except the journal name and year, because I don’t think they are very important and one can easily find by clicking the link to the published paper.
• I searched for all my paper drafts in my computer and added slides whenever I found them.
• I merged “Conference proceedings” with “Other publications” because I don’t see a reason to keep proceedings as a separate section given that I don’t have many.

Maybe it is not the best use of my time but I created a “Talks” page, which lists past and future talks and presentations. After spending all afternoon tweaking the code, I created something satisfactory. For now I included only talks in 2023 and 2024 but I might add past ones.

I am still waiting for the replacement battery for my 2016 Nissan Leaf. It’s nearly 9 months wait now.

Nissan Leaf after 7 years

In 2016 I purchased a Nissan Leaf. Given the technological progress in electric vehicles, now it’s almost a joke but it had a 30kWh battery with around 110 miles of range. Including everything (tax, registration, etc.), it cost 44,142 dollars. My employer subsidized 10,000 and I received 7,500 federal and 2,500 state tax credits, so at that time I thought it was not a bad deal. 110 miles of range seemed enough to do daily chores, and for road trips we had been renting a gas-powered vehicle. This was our only vehicle in the household until 2020, when we bought a Tesla Model Y.
