You need to go to a ripperdoc and buy a cyberdeck upgrade. Then you'll go from only 2 program slots to something like six (depending on the upgrade you buy) as well as more RAM. Really opens up combat hacking options, and as far as I've seen this is never explained.
Exactly this. One of the rare (blue) hacks fries enemies for a good hit of damage. I've seen it one-hit a lot of trash-level mobs. You can tag em in slow-mo, run around a corner while the hack uploads, then pop back out and finish them off as they react to the pain.
