  • Why would a watch go blank after a few weeks or months of having a new battery put in it?

    I have a CASIO watch that had its battery replaced 3 months ago. The new battery should still be good for at least 2 years. However, the watch went blank a few days ago. The seal was not sealed tight enough. Having noticed this, I did not get the watch wet. What could be the cause of the watch going blank shortly after having the battery replaced?

  • What is the likely future of post-pandemic air travel?

    Air travel has gone through a very bad shock in 2020. It will likely take years before air travel returns to 2019 levels. While air traffic has no way to go but upwards, a number of things could happen.

    * Airlines could be facing financial weaknesses for some time to come.

    * Capacity could be normalized in a staggered way over 3 to 4 years. Thus, vacationing will be more limited until capacity is normalized.

    * Airline bankruptcies could occur even with federal aid.

    * A drastic reduction of airline staffing could lead to a reduction in the travel industry labour pool. So, as demand increases, not all of those who want to travel by air could do so.

    This leads to a depressed travel industry. Once the pandemic is over, will governments be promoting air travel to speed up air travel recovery while subsidizing airlines for a few years to come?

  • In Thunderbird, is weekly volume graphing possible?

    Thunderbird searches can display bar graphs of the number of emails with matches to a search criteria such as a person's email address. Is this possible for a search for all sent emails? All sent emails would be included in the search. The output I am thinking of is a set of bar graphs indicating the amount of emails sent in a given time period.

  • How did Japanese occupation of Korea change Korea?

    In Korea, the Japanese ruled the country for 35 years. Usually, during an occupation that long, changes occur in the occupied country throughout the years. These changes often become permanent. Once the occupation is over, society returns to a new normal. While most unwanted changes can be undone, certain changes remain in place in society which are seen for generations and remain in place. What are some examples of such changes in South Korea and Korean society?

  • Are leaders of political parties in power who know they will lose on election day, less committed?

    Often, parties in power for more than 10 years have leadership issues. One example is a leader who admits that people don't like him/her and that their party will lose the election when support is low. Such statements do no good for election chances.

  • For tourists, what is the best way to have a left purchase mailed?

    Items left in a store upon purchase are normally expected to be picked up by the person themselves. This is true for locals or people residing in a place within an hour and a half distance to the store. However, for tourists who live up to 6 to 8 hours away, driving back to the store to pick up the item is not the best option. Packaged mail delivery is more appropriate. However, the person getting the delivery may very likely have to pay a fee. Would a courier service be normally required for the delivery of the item?

  • In a Help Desk environment, how many people should be contributing to a ticket at most?

    It is not good to have too many Help Desk members working on a ticket, however, multiple people may have to work on a single ticket. What would be a good maximum limit to how many people should work on a ticket? Overlap of work should be avoided. At the same time, workers on a Help Desk have to do work.
