Acer C720, its swollen battery and RTC.

| June 24, 2017 | Updated: March 14, 2020

A few days ago I pulled my Acer C720 out of the nightstand and noticed that it has a strange shape…
It’s keyboard was bulged toward the screen so the laptop can’t be closed completely.
Battery was swollen.
After I have removed the battery everything seems to work well except the wifi. Wifi couldn’t connect to anywhere and somehow I understood that the problem is incorrect date in RTC. RTC really had some fake date in the far future. It seems that there is no separate CMOS battery in this laptop. And I was needed to find the way to fix it.

Simple Perl CGI shopping list

| June 23, 2017 | Updated: March 14, 2020

In my family we often used pieces of paper to write down a list for the next grocery store visit.
I think this is a common situation and many people are using such lists.
After some time I have begun to feel some inconvenience because sometimes I forgot to take these lists to the grocery or I couldn’t understand a handwriting.
So I decided to do a simple web service on my own web server, that will serve as a shopping list.
