I would like to use date format for “Modified” field YYYY-MM-DD instead of the default MM-DD-YYYY. So I created a calculated field with the code: =TEXT(Modified,”yyyy-mmm-dd”) But at about 70% of the case the result is 1899-Dec-30 (That is not correct). This is an auto generated field so it can’t be blank. Also if IRead more

Background: I have a MySQL table that stores ip addresses for a very large amount of hosts. It’s a simple table (host xyz -> ip1, ip2, ip3). These hosts will write a flat file with it’s ip addresses to the central server (where MySQL database is kept) and a simple BASH shell script will processRead more

I take a little with margin. I create swap file of size 15gb: sudo dd if = /dev/zero of = /home/sergey/swapfile bs = 1M count = 15000 Security: sudo chmodRead more

The problem is I can clearly see that my input is not interpreted correctly. eq1 = x'[t] = – y/((x – t)^2 + y^2) What it is interpreted is the following 1 == Derivative[1][x][t] == -(y/((x – t)^2 + y^2)) I don’t know why. My Mathematica version is 11.2.Read more

I created a block view of my products in an accordion link. The problem is that variations and quantity of products do not appear. If I place the block outside the accordion link, the variations and quantity of the products works. Here is a shop page with a block placed in the accordion link “LesRead more

I want to evaluate a convolution for a stripe function and a Gaussian: stripe[x_, d_] := If[EvenQ[Quotient[x, d]], 1, 0] gaussian[x_, \[Mu]_, \[Sigma]_] = 1/(Sqrt[2 \[Pi]] \[Sigma]) Exp[-((x – \[Mu])^2/(2 \[Sigma]^2))]; Plot[{stripe[\[Tau], 1], gaussian[\[Tau], 0, 0.5]}, {\[Tau], -10, +10}] Then, the convolution I want to evaluate is: Convolve[UnitStep[\[Tau] + 5] stripe[\[Tau], 1] UnitStep[5 – \[Tau]],Read more
