Manners

    From a year ago, I was fond of joining the international meeting, with all the westerners and some few Koreans and Japanese, but few Taiwanese only joined for a meeting. Pleased with the westerners, my recognition was learners from South Africa, South America, Columbia, Venezuela, Brazil, Iraq, Egypt, and etc. They usually greet each other with questions: “How was your day?”, “How are you?”, “How do you do?”. In Chinese culture, the questions “Have you eaten? Or “Where have you been?” are pleasantries equivalent to those of Westerners’ questions.

    Exchanging ideas, agree or disagree is very common in Western countries, but Chinese is trying to avoid political-related discussion, transgender, human rights or gay relationship issue. We are deeply careful about strong negative statements, even though we already knew that, like other countries, are working hard to deal with issues, but still seen as sensitive and should be avoided.

    Westerners have a hard time figuring out all the customs and formalities in Chinese cultures, they almost assume that Chinese customs are like Japanese or Korean ones. When you come to customs in detail, there are some big differences between doing and don’t to do.

    The rules of meeting new friends in a meeting, refrain from asking them about age, salary income, private matter, or unnecessarily questions. Some people may do not feel comfortable answering a question, but they just do not let them know about their feelings. Getting angry or raising your voices is considered a loss of face in our culture. However, Chinese would like to write their emotions in their face when they are irritated.

NAND memory

     The three main parts of SSD: controller, DDR memory, and flash memory. DDR memory usually present when is a cache which speeds up frequency accessed data. The controller just the main controller between the chip inside and the device where you are adding storage device, but not least is the NAND flash, this is most essential part of the SSD.

    NAND memory is a type of non-volatile storage, which means it is unlike the volatile storage devices, it does not depend on any power to retain data. The entire purpose behind NAND flash devices is not only reduce the cost per bit but also increase maximum chip capacity. This will allow memory to come closer to other storage devices like hard disk drives. NAND uses electrical circuits to store the data as blocks, once the electric circuit is broken and the power is detached. NAND storage continues to retain the data, using semiconductor. Each NAND essentially has two gates control and floating gates. These gates ensure that data flows perfectly and if you want to program one cell, a voltage charge is sent to the control gate, and the electrical charge is stored in the floating gate.

    There are 4 main types: SLC, MCL, TLC, and QLC. The main thing that distinguishes them is how many bits that each cell can store inside. As the name suggests SLC or single level cells store one bit of data per cell. MLC or multi-level cells store two bits of data per cell. The number keeps climbing, and in the case of TLC or triple level cells, we get three bits of data per cell and then in QLC or quadruple level cells, we can get four bits of data per cell. The greater number of bits, the more capacity each cell can hold. This means QLC can hold the maximum level of storage and SLC can hold the least. Unfortunately, the maximum amount of storage comes at a cost, and that is speed and endurance. This means that even though SLC flash can hold the least capacity and it also the fastest, and more precise, and of course, the most expensive. Due to its cost, these chips are mainly used in industrial use, not in the consumer space. On the other hand, MLC is much cheaper than SLC, and it has far greater capacity as well. However, its durability and speeds are not up to SLC’s level. As we keep going up to TLC, and the QLC, the price does get lower but so does the durability and speeds comparatively. This is why TLC and QLC are mainly reserved for consumer level usage while the former 2, the MLC and SLC are mainly used by enterprise. However, TLC SSDs are now being introduced in enterprise. Up until now, we need to talk about how the cells are arranges.

    Originally, memory cells were arranged side by side which was called 2D NAND. Nowadays, we have 3D NAND technology. The memory chips are stacked on top each other. The whole point of this is to make the device run much faster and more efficient while simultaneously holding more information. Here at Sabrent our drives use 3D NAND, 3D NAND has many advantages over the traditional 2D NAND as it has higher density and can be written and raised more times than 2D NAND, because it has larger memory cells while 3D NAND has existed for more than a decade now. It has recently entered the market with some incredible developments as it has been able to provide lower power consumption, better performance and lower cost per bit of storage. As TLC and QLC memory with 3D NAND grows increasingly popular. One cannot help but wonder which is better and what are the pros and cons of each. In some cases, bigger might be better but when comparing QLC and TLC, TLC is able to tolerate a much higher number of write and arrays operations due to its fewer bits written per cell.

Living arrangement

     I have been lived in a rural area in West of Taiwan. I rented a house and live with my landlord and his wife in a terrace house.

The world is not a safe place anymore

    The world was never a safe place again. There are millions of creatures, animals, plants are living in this planet. The majority species is the people, they want to use you, to trick you, to steal you, to rob you, they want to manipulate others no matter on micro or macro scales. They govern, enact laws, and process all the harmful things to people.

    Some 20 million people died during the first 2 years of the COVID-19 pandemic, latest news released some variant virus at the latest series estimated of the double or triple times the death toll. No matter how serious of the report said, people still deliberately travel around anywhere for their own satisfaction.

    Climate change have dried up rives across the continent of Europe, which it is in the grip of its most extreme drought in decades-record breaking heat waves. The drier winters will more likely to become the new normal due to human-induced global warming. The situation is unprecedented, even more catastrophic drought happened in Middle East countries. The people living there have no chance to survive, it is the matter of time until they die.

    The death from wars have gone down dramatically over this decade.  There is always some dictator president will come to power everywhere actually break out a lot of families in this world. The food prices rocketing by the conflict in Ukraine, leaving many families unprotected and increasing displacement. Wars are inherently violent, but destruction of resources can create more devastating harm than weapons and bullets. Refugees are often fragile to be provided the shelters and food, as well as disease.

    I believe that the world began becoming a more dangerous and unsafe place. Conflicts, wars, along with weather events associated with climate change, are the main concerns for living in this planet. I felt lucky that I never had a kid, I do not need to worry about his/her environment in the future. The world will keep getting worse until people realized why so many things are out of control.

Dementia

     There are various disorders and factors contribute to the development of dementia. Most of the common forms of dementia cannot be cured or irreversible brain damage. Early detection of symptoms is crucial which can help you to manage the condition and plan ahead, as some causes can be treated. If your family member has this kind of medical history, it can provide important tips about the risk of getting dementia. It might ask about how and when symptoms began, changes in behavior and personality. Dementia affects patient’s working memory, processing speed, executive function which include the ability of focusing or paying attention.

    I became obsessed with this topic when my father got the delirium, it might run in the family. I strongly believe that “an ounce of prevention is worth a pound of cure”. It will never too young or too old to begin thinking about prevention. I am trying to understand to the best of my ability the kind of foods and lifestyle modifications that I might be able to integrate into my life to help minimize my risk of developing any kind of dementia.

    If you exercise regularly, get the good quality sleep every night, you will find the way of managing your stress, anxiety or depressed. There are some foods that we can eat that can help protect your brain as ages.

    Start with almonds, all nuts are healthy but almonds particularly will be highlighted because they are a top source of dietary magnesium. Almonds are also very rich source of vitamin E. Second with blueberries, blue corns, purple potatoes, and red onions, mostly blue colors which rich in anthocyanin. The most rejoice choices are dark chocolates, it provides the abundant source of dietary magnesium, and full of cocoa flavanols that can have protective effects on cardiovascular health. But need to make sure that the chocolate has 85% or higher over it.  The cruciferous vegetables are also important, low calorie, but rich in folate, various of vitamins, and fiber which can provide the antioxidant and the elements of detoxification. Up next, avocado is an all in one brain food that contains the highest concentration of fat protecting antioxidants of any fruit or vegetable. Avocados are packed with carotenoid, lutein and zeaxanthin which can help boost processing speed in the brain. The next meat is the wild salmon, it provides omega-3 fatty acids, which its compound can create brain healthy new cells.

Retirement

     Retirement is totally different than in the past. My mother is hardly to retire at 70 years old, because she loves mingling with people and rambling around any places. She can choose to work or not to work, not because she has to, but she is willing to earn more for her needs. There is nothing can define as the retirement age. It may fluctuate by country’s economic stability.


    As a worker in Taiwan, the mandatory retirement age is 65 years old but you should not be forced to retire unless disability to perform his or her duties. If I want to retire at the earlier ages, I must have worked over 25 years. I am afraid to be bored after retirement. I have a higher opportunity to meet the goal to retire at 55. Usually, I will end our career based on how steadily you have been employed and your healthy status, particularly after 55 years old. I always tried to do the work my boss requested. Learning how to work in effective and essential ways and keep curiosity in learning new things. I always enjoyed what I did as always, which meant fun at work, better output, better paycheck. I can make some meaning contributions, stay busy at something. Many are still working into their 60’s or 70’s, it is an enormous change for them. I was lucky that I didn't have the child and over 20 years in the service industry. If I have made a lot of money, I will spend my rest of my time doing charity works especially in improving the lives of stray dogs or cats and abandoned animals. I do not mind if I stay in the city or in the rural place, no matter the places or income, but I intend to look for another job, I just want to find my values of work-life balance.

Community

    I am living in a Green View residential community in rural area in Hsinfeng County, offered at least 500 families, spans over around one kilometer. It located near lake where far from city center around 20 kilometers. Amenities included basketball court, tennis court, playing ground, parks. All of the design elements were planned to create a tight-knit sense of community where all the residents will love where they live.

    Before I lived in this community, there had had three contractors who filed for bankruptcy in the midst of the job or disappearing from the project. The immediate impact was the electricity or water supply in some families. The long-term disruption of it was some dilapidated old building has been idled for years.

    The most favorite part is the dog parks in the community, I could walk my dogs in different places. There are rarely to find an available dog parks in a city. I found it is very convenient for me to walk them every day. I knew some neighbors who are same with me loved walking in the park. Some old people usually walk or ride an electric wheelchair with their home nurse. The playgrounds in a park are not pretty safe enough for the kids but some children still love running or chasing around there.

    Smoking scorching heat temperature made plenty of creatures sluggish in the park in summer. The heat basically encourages the dog-day cicadas to make the noisiest voices in the world and the notorious mosquitoes to annoy you everywhere. However, most people would like to sit down in a large-arm steel chair under trees especially summer, usually chatting or greeting with other strangers. The vibe was great and harmony, if I had a child in the future, I may live here for the close-knit group community.


How can I prepare for a war?

    There is a growing tension between China and Taiwan, the military exercises continue on Sunday morning, close proximity to Taiwan. The White House released a statement saying that it believes China’s drill is an attempt to change the status quo in the Taiwan Straits. During the demonstration of Chinese forces position to the surrounding of Taiwan, dozens of ships were forced to shift their routes or slow down to keep out of the danger zones. The economic blockade started happening and challenged the Taiwan government’s capability on handing the crippling effect on economy.

    Based on my analysis, the price of import or export goods should be rocketing and impact the New Taiwan dollars. The commercial flights were also interrupted by China’s military exercise. Some airlines suspended flights because they were averting the designated zones. To conclude, any blockage of Taiwan’s airspace would have profound economic effects.

    As I am a foreigner living in Taiwan, I assumed that China ready to attack Taiwan in an instant. Firstly, I need to understand the war situation and well prepared for injury, having loved ones injured. The most important goal to have when a war begin is to survive. Buy a survival kit and practice how to use it. Knives hidden in somewhere where you can easily to take it out when you are in danger. Prepare a waterproof sleeping bag and get a flashlight with battery packs. Buy some bottles of water in your room to avoid dehydration.

    Most of us do not think they will be involved in the combat as always. But sometimes combat comes to you, firstly, hide yourself if you could. But that could not always be avoided. So I need to try my best to fight my way out. I need to learn how to shoot weapons, practice killing someone on a dead animal.

Do you fear of changes?

    Life is unpredictable. I cannot plan everything in my life. Things would not happen exactly the way I anticipate. When my customer’s business has been ceased to develop new products suddenly by last week, how can I handle a job in a new organization? What should I prepare before changing to a new position? When a Chinese-Taiwan war seems to be happen, what should I move to avoid the disastrous consequence? If my family request me to return back to Malaysia, what should I do with my love dogs?

    Change is a part of life. Some of it will come as blessings, other parts will come as lessons. Pain is a part of life. Yet suffering the climate change, human conflicts, life changes—good or bad, we cannot control over it. Sometimes I just have to accept them and roll with the punches. It is not easy to come with change, but I do have options to choose my response to change, better or worsen.

    When I am comfortable, I am stagnant in a comfort zone. I am in charge of my own story. No matter which choice I made, or how many times I went back to the drawing board and started over, eventually come to an end.

    Impermanence is one of the most basic elements of life. Change is inevitable. If the war is coming, I can just accept it by sitting around and waiting for it to happen, or I can actively craft my response to it before it come. China is holding a second day of its biggest military drills around Taiwan. Most of Taiwanese are looking at the developments with caution instead of excessive fear. However, I have transferred my 80% saving accounts amount to the US dollar in two days. Beyond that, I have bought a lot of canned foods and several packets of rice on Monday midnight. It sounds sarcastic, but it might not mean to be. Fear of the unknown is natural, but it does help you to avoid some inconvenience.

The importance of punctuality

    I grew up in a strict environment, where being punctual is a respect behavior or showing your responsibility to the society.

    I had a vivid memory, when I was learning English in a tuition class on the second floor of an older building, my teacher usually took a lot of shirt clips and punished the students who were late to class or failed the exam before leaving the class. I was too afraid of being scolded by the witch teacher or my ears were hardly pinched with the shirt clips when I was studying. My head was spinning or easily anxious after being pinched after thirty minutes.

    In my elementary school, if a student was late to the convention hall, he should be punished by standing in the back of hall. It allows all the teachers and students keeping an eye on you, it was visible to all the persons who walked passing through the door of the hall. It is a cruel punishment because it hurt my feelings to stand in one place for a long time.

    When I grew up in high school, I used to take a school bus in every early morning. I had to get up before 5:30am and run as fast as possible to reach to the bus station in order to catch the bus in 5:40am. If I failed, I had to take the bus, at least two transitions with 30 minutes to get to my school. Therefore, I had a body clock on that period, I could automatically wake up without clock warming.

My hometown

     I grew up in eastern part of Kuala Lumpur, Ampang, which means dam in Malay. Ampang was a historical tin mining hubs which far 20km away from Kuala Lumpur. Even though it is located in the city, but I did not feel like I was living in the city. The population of this village around 700 thousand inhabitants, most of them are not rich people, amid the traditional shop, dilapidated food eateries, and very old local groceries. Here still standing were the century-old buildings which were built around 1920.

    In Chinese society, the famous landmark in Ampang is Nine Emperor Gods Temple, the 160-year-old temple, giving the historic information of the place and attracted more Chinese to live here, predominantly from the Hakka, Hokkien, and Cantonese communities. My father was the former carpenter, handmade the furniture in furniture factories which located in the wet market behind the main street.

Since I was a teenager, I would like to wander around the basketball court, because I used to buy some fried chickens or playing with some stray dogs. It was a boring place, but I would like to walk in bare feet in raining day

    Every Sunday morning, we used to worship God in Ampang Methodist Church. The service lasted one and half hour and ended around 11:30am. Generally, our family members will be joined together in the most prominent restaurant, Ampang Niang Tou Fu nearby church. My favorite food was the minced fish ball and the combo of pork paste. The food there is very local but nice. However, the waiters or the boss always arrogant because there is a bunch of customers asking for services in a restricted area.

    Three years ago, before pandemic contagious, I visited the Ampang area and found there is no any major improvement on the building but the basketball court has been refurnished and covered by a big roof, there are many teenagers were playing basketball together and felt relaxed. I ate my favorite noodles in Lim Kee Noodles House with my sister, unfortunately the restaurant has been burnt down two years ago.

    I reside in Taiwan and have lived here since twenty years ago. Almost twenty years, but my parents raised me and my sibling in Ampang, Selangor. Even though I do not live there anymore, I would love to see it again in one day. But I cannot, physically. My father with dementia, but he is able to remember all the numerous events from his teenagers to older years, and he brought a smile to his smile. That is why he feels nostalgic. I hope he will be keep going to be healthier if somedays he can go back to his hometown.

A letter to inform a business closure

    Eight years ago, I was interviewed with big boss if I was willing to transfer departure from lab engineer to R&D designer which dedicated to Intel products. This will be my opportunities to learn more new things in semiconductor factory, therefore I decided to agree with it.

    The first year of my joining majorly focused on the second source of substrate vendors, it is really easily to revise the proposal, which only revised the part number of the dedicated vendors. However, there is still some delamination issues, capability issue or vendors issue. I felt perplexed when I started implementing the low cost solution, especially the silver wires reliability issue. At least three times to cope with the silver wires corrosion issue in packaging semiconductor factory. The process team was struggling to increase the purity of nitrogen gas, tightened the window gate of wire bonding workability. Finally, all NAND products could be transferred from gold wires to silver wires after two-years effort.

    When the new 3D X-points products were developed jointly by Intel and Micron on 2015, the new type of memory products which alleged can enhance the speed faster thousand times compared with NAND products. I started rambling to develop different structure or packages in order to meet the end customer criteria. Unfortunately, there is barely fewer products has sustainability and continuity to go high volume production.

    Almost seven years, I have dedicated my life and effort on designing and restructure the package to replace NAND and DRAM, but it finally failed to capture the goal on emerging memory. I just saw their procrastination for decades, they just simply leveraged some similar devices from old devices to new devices. There is no any significant changes in technology.

    Intel is a prestigious company which has the largest supporter, the USA, if any lack of money, just stab the competitors in the back and convince the government to invest more money into their pockets. I can see that Intel has no more any big trusted investors in this great recession period. Even though Intel has announced the discontinuing the development of 3D X-point, but I still looking forward the future of culture changes or any shift in focus to bring new better profits in CXL interface.
