Fighting with computers

  Ok, so you have your NAS and you have built it with some redundancy (RAID). But what if the whole thing dies (the system motherboard)? Well, at least you will need a spare unit. Nonetheless, having all your data on a single device that can die anytime does not seem like a good idea, so some sort of backup plan is needed. One possible idea is to have a second NAS unit that will be kept in sync with the main one, so that you can switch it back to be the main one in case of a failure of the main unit. Not cheap but a workable solution. However, certain risks like a robbery or a fire need to be covered, so keeping the two NAS at the same location is not a good idea.  So one possible solution is to have the backup system remote and to connect it to the office system VPN, so backups can take place. This opens up an interesting networking problem if the VPN server is not run by the NAS box, as the VPN addressing space is going to be different than the office network addressing spac...

My first recommendation is not to use that feature, but if it is a bit too late for me, as I did use it in the past. And old code needs some care from time to time. STL files represent triangular 3D meshes, but do not support color in any shape or form. However, some non-standard way of adding color has been used by some companies in the past, and somehow, here we are, using color on STL files.  If you do that, you may wonder what the actual colors are in your STL files, as this feature is quite sketchy for several reasons. So I asked DeepSeek to create me a single-page web app that could help me answer this question locally (without sending your 3D mesh to a web server). Not that the AI was completely willing initially, as it delivered only a shell with fake info, but a bit more persuasion produced a very usable result I am sharing with you here . I decided to write this post instead of placing the AI blog entry (which I created and reviewed, though).  I followed the AI advic...
