Day 26: Re-learning Chinese as a Heritage Speaker

I recently read How Will You Measure Your Life by Clayton Christensen on recommendation and now I'll propagate the cycle by also proselytizing the book. It's an accessible, self-reflection provoking read with great insights for cookie-cutter career-conscious yuppies. I was personally galvanized by the discussion around "Investing for Future Happiness" and "The Risk of Sequencing … Continue reading Day 26: Re-learning Chinese as a Heritage Speaker

Day 25: Special Meals

Disclaimer: I don't take good food photos. Here's some weird corn instead. Food for thought that recently came up at the dinner table: what makes a meal special? Specialness is a tricky idea, heavily influenced by individual perception. A meal is never categorically special - you and I perceive, experience, and subsequently feel differently. This … Continue reading Day 25: Special Meals

Day 23: Jiu Jitsu: The gentle art of folding clothes while people are still in them

An oldie but goodie For the uninitiated, if you've ever seen adults wrestling on the gym floor whilst wearing fancy pajamas, that probably was jiu jitsu, a submission-based grappling martial art. New folks might find jiu jitsu inaccessible relative to more self-explanatory martial arts - without understanding the techniques, it looks like an exercise based … Continue reading Day 23: Jiu Jitsu: The gentle art of folding clothes while people are still in them

Day 21: WordPress Themes

I've started playing around with the aesthetics of my blog by exploring different website templates. A few quick thoughts: Choosing a WordPress themes is an exercise in tedium. Decision fatigue is incredibly real and unfortunately, quantity of choice does not translate into quality. Medium does a good job of having a one-size-fits-all template aesthetic. This … Continue reading Day 21: WordPress Themes

Day 20: SPY Puts

A few weeks ago, I rolled my SPY put into SPY 200529 P 260, entering at $6.49 mark ($280 SPY). Since then, SPY has done me the favor of consistently moving sideways, even testing a $290 SPY regime. The mark on this position is currently $2.02 ($283 SPY). $-447 PNL can be explained by ~-$300 … Continue reading Day 20: SPY Puts

Day 19: The Intrepid Spirit of US Markets

The front cover of this week's Economist highlighted the growing gulf between the stock market and the real economy. Over the past two months, many of us have watched US equity's rip-your-face-off rally with significant disbelief and nontrivial FOMO. Personally, I'm still waiting for another correction, but I'll admit maybe my mental markets model is … Continue reading Day 19: The Intrepid Spirit of US Markets

Day 17: Links for Context

Housekeeping today. I've received feedback that many of my posts are too inaccessible for a lay person lacking the necessary context. There's a fine line between adequately grounding your reader and providing original commentary. My strategy is to hyperlink the reader to the necessary context elsewhere, otherwise I run the risk of becoming too skilled … Continue reading Day 17: Links for Context

Day 16: World Order and Diplomacy

World Order: "Vintage Kissinger" Hillary Clinton refers to Henry Kissinger's World Order as "vintage Kissinger." While she undoubtedly intends the phrase as fulsome praise, it makes me far less excited about reading Kissinger's earlier works. Kissinger's writing is both dense and assumes a high level of background knowledge on global political history. If you have … Continue reading Day 16: World Order and Diplomacy

Day 14: HID Deep Dive

Yesterday I wrote a demonstrative example of cloning an unencrypted HID RFID access card. You might complain that it was exercise in Proxmark magical keyboard incantations. Well buckle up reader - today we dive into the details. Image 1: Proxmark scan data from reading our HID card The above screenshot (Image 1) shows the results … Continue reading Day 14: HID Deep Dive

Day 13: HID Cards

Proxmark 3 Easy, original HID card (note the printed card number 67924), and rewritable T5577 card My first task is to clone some old RFID cards I have on hand. Today, we're working with a HID iCLASS card, commonly used for building access. Our Proxmark is able to identify the card type and read the … Continue reading Day 13: HID Cards

Day 12: RFID Cloner

My first introduction to the technological transhuman movement was a few years ago when a friend showed me his implanted neomagnet and NFC chip. Once the nerves had healed around the neomagnet, he was able to feel EM waves emitted from nearby electronic devices - a useful trick for an electrical engineer. He used his … Continue reading Day 12: RFID Cloner

Day 10: First Day of Spring

Today's weather is too beautiful to spend indoors on the computer. Spring may have started in the northern hemisphere on 19March, but NYC weather only just became aware. I'll see you folks on the roof.

Day 7: Risk Tools

I've noticed some glaring deficiencies with ThinkorSwim's risk platform. Relative to the risk ecosystem at my previous job, ThinkorSwim offers only a barebones conceptual understanding of risk. While undeniably UX friendly, the risk platform lacks some obvious analytics and un-intuitively organizes other risk data. Every morning when I start my trading day, I need to … Continue reading Day 7: Risk Tools

Day 6: Morning Runs

This morning's run metrics on Strava: 5.8 miles, 8:38 min/mi Morning runs never cease to impress me with how energized I feel at the start of the day. That being said, the hardest part of the morning run is waking up early. Given the current COVID environment, morning runs are the only outside runs that … Continue reading Day 6: Morning Runs

Day 2: Options Are Hard

At Goldman, I observed that the closer you worked to markets, the more boring your personal trading account. Most folks on the trading floor (myself included) just jammed it into US equity, with some tech and crypto bias. A combination of trading restrictions and the zeitgeist of unbeatable markets leads most people to just passively … Continue reading Day 2: Options Are Hard
