Talk:Matrix with two diagonals

Dependence on a potentially insecure direct link to a JPEG

The paucity of that task description leads to a dependence on directly loading an unknown JPEG.

JPEGs are susceptible to exploits, and it seems a pity to risk the impression of obliging others to do something which is potentially insecure.

(My advice to others would be: never click on a direct JPEG link offered by an unknown host). Hout (talk) 09:19, 17 February 2022 (UTC)

Although I'm confident the author himself would never do anything malicious, you're right to express caution about viewing external images.

Fortunately (if you haven't guessed already) you can work out what's required from studying the Ring code which is drawing a square matrix which has 1's on both diagonals and 0's elsewhere. --PureFox (talk) 09:38, 17 February 2022 (UTC)

I wonder if there isn't a line that needs to be drawn at the point where the quality of task descriptions declines so far that they are not even secure (let alone adequate). Hout (talk) 10:40, 17 February 2022 (UTC)

Suggestion 1. Delete that link to a JPEG. Some of use may well feel sufficiently protected by our assessment of CalmoSoft personally, but we know nothing about the security of the hosting site.

Suggestion 2. Replace the JPEG link with a textual matrix and an adequate description. Hout (talk) 11:05, 17 February 2022 (UTC)
