Dear Vishi, this is my weekly logs from Jan 29 to Feb 4, 2024.
At a casual lunch, my colleague told me an intriguing story of "Typhoid Mary". Mary Mallon was an Irish immigrant who worked as cook in the United States during the early 20th century. Many of those who ate her meals, fell ill yet she remained unaffected.
Mary was a carrier of Salmonella typhi, the bacterium responsible for typhoid fever, hence the moniker "Typhoid Mary." She was a asymptomatic carrier. This means that although she carried the bacteria and could transmit it to others, she did not exhibit any symptoms of the disease herself.
Mary Mallon's saga took a dramatic turn when she was arrested and quarantined by the health authorities. However, she contested her confinement and was eventually released on the condition that she would not return to her previous profession. Unfortunately, Mary violated this agreement and resumed her work as a cook, which led to further outbreaks of typhoid fever.
Why do some people are asymptomatic and some are not? Even with SARS-CoV-2, some people remained asymptomatic.
What's the difference between virtual machine and docker?
Virtual Machine includes a full fledged Operating System (OS) that runs on a software layer that manages resources called hypervisor.
Docker on other hand, share the host machine's kernel but operate in isolated user space. Docker relies on on lightweight images that include only the necessary components, resulting in faster deployment and more efficient utilization.
If I say,
tu me partiste el corozon
It means you broke my heart. But If I have to say like
tu me rompiste me vaso
"Rompiste" is specifically used for breaking in the sense of shattering or damaging something, like a glass. On the other hand, "partiste" is more commonly used for breaking in an emotional or figurative sense, such as breaking someone's heart.

Malaysian passport bears the inscription "This passport is valid for all countries except Israel". This reminded me of Pakistan has similar inscription on its passport, "This passport is valid for all countries of the world except Israel".
Israel doesn't have diplotmatic relations with either Malaysia or Pakistan. The conflict of Israel-Palestine has significantly affected the sentiments of Muslim majority in both Malaysia and Pakistan.
Also, Bangladesh doesn't recognize Israel. In Nov 2003, Bangladeshi journalist Salah Choudhury was arrested for attempting to fly to Tel Aviv to attend a seminar and was booked for "sedition, treason and blasphemy".
On Mac , if you want to open submlime text via command line :

Difference between futures and options. With a future contract, you are obligated to buy/sell that asset at later date. It's like pre-ordering something at a fixed price, no matter how the actual market price changes.
Options contracts gives you a right rather than a obligation whether to buy/sell that asset in future. But you pay a fee for that choice. If you select not to buy/sell that item, you lose that fee.
With Options, a call options is like having the right to buy and a put option is a right to sell.
The payoff for a call option is
C = max(ST - K, 0)
P = max(K - ST, 0)
K is the strike price (the price at which you sell the stock)
ST is current stock price.
