Can we drastically reduce the community spread?

I wonder what it would take to have shopkeepers, cashiers, and others who regularly encounter customers in close proximity to wear masks (aka respirators.) The 2018 Cambridge pandemic study had found that these people categorically become superspreaders during an epidemic, and by having them either vaccinated (not an option for now) or isolated, we can reduce the number of infections by 40%.

I understand that the capacity to mass produce masks is limited here in the States, and the leaders have promoted policies, or public orders accordingly, so I’m not advocating that everyone wear masks, but I think it’d be a good idea to have these potential superspreaders to wear them.

Wi-Fi 6 is coming

The upcoming standard is called IEEE 802.11ax and it will be available starting in the fall of 2019.

The latest standard we’ve been using is called 802.11ac, and although we haven’t heard Wi-FI 5, the new standard will be widely promoted as Wi-Fi 6 (as the 6th generation).

The new Wi-Fi 6, 802.11ax uses both 2.4 GHz & 5 GHz and has features such as multi-user, multiple-input, multiple-output (MU-MIMO), Orthogonal Frequency Division Multiple Access (OFDMA) — allows more devices to simultaneously operate on the same channel — throughput of 9 to 10 gigabits per second in optimal conditions. It also supports WPA3.

For reference:
Wi-Fi 5, 802.11ac (only uses 5 GHz)
Wi-Fi 4, 802.11n (uses both 2.4 GHz & 5 GHz)

What not to do as a new IT director

  1. Devalue existing employees
    1. by promoting someone that do not deserve promotions
    2. by putting forth product ideas that do not consider products already in use
    3. by hearing out all other inputs except the existing team directly reporting
  2. Promote a new product that “I” will be making
    1. with no due consideration of existing products because they are inferior to whatever product that “I” am going to be introducing
  3. Have existing developers resign or make exits through the means of attrition
    1. by giving all new, significant responsibilities to newer crew
    2. by reinforcing a false idea to the upper echelon of (IT) ignorant management that existing developers are incapable, and somehow out-of-date
    3. by continually reinforcing a message that someone new and better will be hired that will do the job better
    4. by continuing to hold meaningless weekly meetings that shut down all meaningful and creative inputs by repeatedly telling people that new, and more capable person will come in

  2. 들기름을 넉넉히 쳐서 야채 (양파, 호박, 당근)을 올려 볶다가 30분 동안 뿔린 쌀을 넣고 투명해 질때까지 볶는다.
  3. 육수를 넣고 팔팔 끓여주고 약불에서 20분정도 더 끓이 다가 걸죽해지면 새우젓 (1/2 TSP) 을 넣는다.
