I also lived in Madrid. 1h15 means you were not in Madrid, but in one of the surrounding towns. 30 minutes in a car is enough to get from any point in Madrid to any other (assuming clear traffic).
It's obvious that people outside of the areas where transport is dense enough won't enjoy all the benefits. This is a usual complain about all dense public transport areas, but it simplifies to the fact that you were not in the area with dense coverage. In the case of Madrid, Metro is only dense enough in areas surrounded by the Circular line. There's also a very dense bus network that covers everywhere within M-40 and even some areas outside it (some bus lines can be hindered by traffic though, there are bus lanes in most critical spots but there's always some unpredictability).
Also, you're wrong on the closing time, it's been 1:30 AM for a long long time. That's the time where the last train departs on each line, so it's possible to catch trains at almost 2 AM depending on where you are. By Madrid standards, if you are out and about at 1 AM it means you are in a bar or in a party, and it's time to decide whether to continue through the night and get back when Metro opens again at 6 AM, to use a taxi to get back home, or to use the night bus network if you're lucky to be near a stop and willing to wait for it.
Because public transit, done well, is the fastest way to move around. It gets you everywhere, even to places personal vehicles can't reach. It's a lot cheaper. It generates hubs of activity that keep cities lively and relevant. It doesn't get stuck in traffic. It doesn't need to be parked.
The benefits of good public transport are so mind blowing that it's difficult to explain unless you have lived on a city that has it.
Gnutella fell in popularity before Youtube existed. The big reason the decentralized P2P file sharing networks went away was their vulnerability to spoofing. Downloads were slow so it was important to be sure of the quality of the files being downloaded, which meant grabbing links from a website or some sort of forum. And once there's a forum, for some of the sites it was not much of a jump to add a BitTorrent tracker to the infrastructure. Additionally, for those sites that were primary sources of uploaded material, BitTorrent was a much better fit.
Their own greed is causing their issues. They could be doing a million different things to reduce demand, but they don't want to dampen their current growth and have opted to continue scaling up at the cost of quality.
I have a Emacs + Spacemacs setup only for Magit. The base Spacemacs config works well, so I never had the need to tinker with it. Nowadays I don't care much about the rest of Emacs. It stays out of the way, and I keep happily using Magit.
A high end amp+speaker system from 50 years ago will still sound good. The tradeoffs back then were size, price, and power consumption. Same as now.
Lower spec speakers have become good enough, and DSP has improved to the point that tiny speakers can now output mediocre/acceptable sound. The effect of this is that the midrange market is kind of gone, replaced with neat but still worse products such as soundbars (for AV use) or even portable speakers instead of hi-fi systems.
On the high end, I think amplified multi-way speakers with active crossovers are much more common now thanks to advances in Class-D amplifiers.
The Spain blackout was caused by a multitude of reasons. Lack of stability was one of the factors, but there were other causes, such as energy generation facilities disconnecting while the oscillations were still under a nominal range, or a generator ordered to become online to induce stability, that started driving the load in the wrong direction. All this was compounded by a distribution network unable to redistribute or at least isolate the problems to individual regions, resulting in a complete blackout.
All in all, it's several things that need to be reinforced. The distribution network needs to be smarter. The energy generation facilities need to be tested through their entire voltage range, so they can be counted upon. And there has to be more voltage inertia available in the network.
Titanfall 2 has one of the best single-player campaign in recent shooters. You are highly mobile and it's possible (and expected) to parkour your way across multiplayer maps.
Warframe is different, it's focused on PvE (although there's a PvP mode if that's your thing). The premise is simple, you are a space ninja with supernatural abilities and you kill hundreds on enemies on each mission. The game is complex and you'll need to read the community wiki to understand some things, but the experience can be very rewarding.
