Oh dear Senior Developer, you incompetent piece of shit

In cour company we need an online dashboard that monitors logfiles from various interface processes.

My collage and me, the newest company members (for almost 2 years) get the task to build this and get it presented as some intern project where we can try out some more recent technologies/frameworks.
Now in the first meeting our senior team leader told us we shoeldn't use the noew hot buzzword js frameworks.
Reason? They are not proven and wil probably lose popularity next year and we don't want to migrate everything every half year. Plus he had negeative experiences with Angular in some project he had to work on, probably just because his limited JS skils.
So he wants us to use jQuery to build a modern web application.

I get it you don't want to migrate to TheNewHotThing(tm) every year. Guess what? You fucking don't have to. If I build sonting in Vue.js now, it won't stop working when a new framework comes along.
Look at our own fucking ASP.NET Web Forms prooject, that stil works. Just don't deny the usability of modern frameworks.

In our application we now need the possibility to add visit hours to addresses. Each day has 3 possible visit moments with a from and to hour and some indicator, and a comment, like this:
monday_visit_from_1, monday_visit_to_1, monday_visit_ind_1, (repeat for 2 and 3), monday_visit_comment (repeat for all 7 days)

For "performance" they (db admin) decided to add all the fields of all the days as separate columns in the address table, 70 in total.
Besides being a horrible design it is a fucking pain to work with, like find if an address can be visited on a given day and time we need to check a subset of columns based on the day and the 3 moments in this day.

Is this really more performant than an extra table to hold the visit moments and is this something that gets done in more places?

The only thing hard about working with Git is working with people who don't know Git

Thanks, I guess

Since the last update of the company antivirus some things became terribly slow, like IE dev tools, they are standard slow, but now they ere horribly slow, copying a 500MB file over the network to my pc now takes 10 minutes and the worst part is git. Git is unusably slow so i can't use git-tfs anymore and have to use standard TFS again.
And whenever all of this is happening there is always the same thing on the top spot of CPU usage 'trend micro unauthorized change prevention service'.
Oh how I hate that antivirus crap
