  • so-called “gravity batteries” is pretty much exactly a dam with a mini-dam/reservoir at the bottom. When there is an excess, you run the motor to reverse the waterflow to pump uphill into a highe-elevation water retention pond/mini-dam.

    This also helps reduce the amount of outflow water “lost” due to high-demand. Since you could take almost a day to fill the bottom reservoir and spend “wind”/solar to pump back the “lost” water downstream back into the higher-level reservoir.

    Even if things are inefficient wind/solar are “renewable”, so you can keep “wasting” excess to replenish the dam and still make enough money back ( think in-terms of drought, flooding, windy, sunny, cloudy, etc ) you can basically keep the high-output “system” always topped-up with water. And still supply water + electricity as it is needed. There is no “downside”.

    Not everyone agrees. So opinions can differ.


  • So, since this is related to your course and a required part of assignments, get things in writing,

    1. Let the Dorm and ISP know that you need an exception due to coursework.

    2. It might be in your best interest to temporarily invest in your own internet,I think 5G might have low enough latency to manage the connection.

    If all this is for one semester until you move back ? Just get a cheap mini-PC install pfSense or any other firewall/router software to isolate all your devices and Wifi router from the rest of the network. I believe some people have mentioned MAC-spoofing and TTL-reset as ways to bypass detection. And if anyone asks, you can show your written communications and your course requirements.

    Always be on the safe side when it comes to dealing with academics and private orgs.

    There might be a Dept Counselor or Rep you can discuss about your requirements. Even professors can help with some of these kind of things.

    Mighty unpopular opinion here.

    OP you are there at the Uni to learn to grow and pass the course+exams. If you need to do extracurricular activities, please setup time at home, travel home to do those things.

    If home is faraway and you still want to do it, find a reliable off-campus-non-dorm location and do your stuff from there.

    Your main objective is to get through Uni without falling behind and managing your time and effort wisely. If you fail Uni because you focused too much on non-essential activities, be a responsible adult and accept the results of your adult decisions.

    Edit: I never said that OP shouldn’t do non-Uni activities. Just that time+effort has to be MANAGED between the two. Life isnt fair and life doesnt give two shits if you fuck up. That is what being an adult means.

    Edit2: I can see people commenting on Universities imposing mandatory dorm fees. Do you people not choose which university to apply and get accepted? Did you not think…“this uni is very strict, or this uni has a lot of on-campus resources, or this uni has great course-materials, etc etc” … and it would also include “this uni dorm is optional/mandatory and I can live there cheap or live outside expensive or it is bum-ducking nowhere but fields/forests/wilderness” … you did choose that uni to attend and paid up ?



  • A lot of Unis have IT on a shoestring budget.Especially the CompSci dept have the most idiotic IT “professionals” working there.

    Usually it is the Sciences dept like Mech-E or Tech-E or Elec-E who run massive Compute nodes for Rendering Physics or Fluid dynamics or something something research …

    Unfortunately, the Unis that have massive student dorms on-campus tend not to isolate their networks properly and allow students to directly connect to all depts Networks without any barriers. The isolation happens between LAN and Internet which is where most of the controls and filtering happens.

    It would be nice if each dept had their own VPN servers and proper network isolation at the LAN instead of the crazy monkey wiring everything to everything else on-campus.

    In table-tennis / pingpong,

    Equipment Junkies.

    It is both an insult as well as an addiction/habit.

    Amateur and Pro TT players usually have trained from childhood as early as 3 years old tend to have an almost god-like superior ability to learn and relearn in the sport at any age.

    But most folks get into TT at an older age around their late-20s.

    TT reflexes cannot be gained at the later stages of life. Almost a miracle for an older player to “git gud”.

    Hence, you will find the older players have the income to buy equipment used by the Top-10 players in the world. Hence “Equipment Junkie”.

    The number of permutations and combinations in TT equipment is crazy for such a “simple” looking sport.

    Real problem is when you buy all this expensive stuff and your game gets WORSE not better. You “lend” your equipment to other players and all of them seem to play better than you with your own equipment.

    So you spent a lot of money, and don’t want to let anyone touch your equipment ( because it would be embarrassing for them to become “better” players using your stuff while you wallow in misery of not benefitting from your own purchases ).

    So EJs tend to have a extremely absurd amount of equipment that they have spent exorbitant prices purchasing and do not want to sell it to others ( again for fear their purchase is fuelling other peoples abilities at their own expense ) but they keep buying the next “Top-10” world TT players latest equipment without even understanding the sport.

    It is an endless cycle which continues as more new blood is added to the mix and more EJs end caught up in the craze.

    Unless you spent 1000s of dollars buying saucers and hammers and lollipops or something garbage that lets you finish without actually playing.

    I hate these “gatcha” gaming nonsense where you pay-to-win.



  • Im on openSuse Leap 15.5 and I moved to Pipewire back when I had 15.3 I believe. I had that issue where all output devices/input devices got smashed together. I stuck with it for couple of months and I believe the later versions fixed that. Now I am painfree and never bother with audio ever again. I used to have frequent pulseaudio crashes which is why I switched over to pipewire.
