Adobe Flash Player on Website

Adobe Flash Player was retired by Adobe and major browser vendors since the beginning of 2021. By the time of 2025, major browsers (Chrome, Edge that works on Chromium core, and Safari) all DONā€™T support Flash. Which makes some interactive operations inapplicable.

JD.com Leads the Way | Providing Social Security to Food Delivery Riders

The courier job in China has long been regarded as a tough, low-paying, and insecure occupation. With limited benefits and high risks, itā€™s a job that many take on for part-time hours or as a side hustle.

a search over two bandit

An interesting paper recommended by Professor Kimon Drakopoulos: Strategic Experimentation with Exponential Bandits Abstract This paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a payoļ¬€ only after some exponentially distributed random time. Because of free-riding, there is an ineļ¬ƒciently low level of experimentation in any equilibrium where the players use stationary Markovian strategies with posterior beliefs as the state variable. After characterizing the unique symmetric Markovian equilibrium of the game, which is in mixed strategies, we construct a variety of pure-strategy equilibria....

Debugging Victory on Valentine's Day

When I took CS101, my professor shared a well-known truth: ā€œFor every hour you spend coding, expect to spend three hours debugging.ā€ While I never officially timed it, I can confidently say that the ratio often feels closer to fiveā€¦ However, debugging doesnā€™t have to be an endless struggle. With a clear mind and a more organized approach, it can be surprisingly efficient. Today I faced a frustrating issue when checking my blog: the changes I pushed earlier never updated....
