Security agency and "new" technology
3r3118.  
A small preface. 3r3334. 3r3118.  
It all started with the fact that I built a house, and a house without a security alarm can exist in our realities, of course, but nothing can be left there in the slightest degree (the sad cases of the neighbors confirm this). While the decoration was being made inside and outside, the keying and disarming of the key did not cause any inconvenience.

Implementing family bookkeeping with Google Sheets, chewing gum and scotch

Implementing family bookkeeping with Google Sheets, chewing gum and scotch 3r3143. 3r3-31. Soon the new year, and, like last year, one of the most pressing issues for any family is the question “where does the money go?”. We all periodically ask ourselves this question, and it is obvious that to solve it we need intra-family financial statements (as for any organization). I tried to use desktop accounting software as well as mobile applications, but I still could not find a suitable solution. There are good free programs, but they, as a rule, do not have a sharing function, and paid ones require a license purchase for each user. A complete set of criteria that has developed ...
