  • I use Ventoy regularly but im too lazy to setup Grub2 on a USB and load up isos.

    Not sure who these Ventoy fanbois or bros are.

    Yup Ventoy does hide binary blobs and has some dodgy devs and code. Use at own risk.

    Also I dont have any sensitive stuff. So mostly Ventoy is used to install playground server isos and stuff. Not much use for it otherwise.





  • 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.











  • Driving manual takes BOTH Theory and Practice.

    1. Replay potential scenarios in your head and try to predict how you will react.

    2. Re-examine your realtime reactions on the road.

    3. Learn both rules of the road and real-life motorists reactions to rules.

    4. Safety - Safety - Safety. If it feels unsafe, get off the road safely and wait it out.

    Manual driving tips.

    Use the emergency-parking-hand-brake for hill-assists.

    Practice dual-brake-accelerator press/release.

    Practice clutch-release-hold with no brake-accelerator ( fully depressed clutch, quarter-release, half-release, no-clutch … does the vehicle jump forward, at what point does it start creeping forward, what noise is the engine making, how does the gear-stick/shaft feel smooth or vibrating or extremely-stuck, etc etc )

    Practice a reliable gear-stick-shift-shaft action. Turn your wrist outward and push horizontal, and up for 1st-gear. Neutral with a downward wrist and wiggle along the central neutral line. Turn wrist upward and firmly push straight forward for 3rd-gear, and tap gear-knob down and wiggle along central neutral line to confirm gear-stick is in the neutral, etc etc.

    So by judging how traffic behaves and by establishing clear personal good gear/manual habits, you can improve your reactions.

    Look forward of the vehicle for less than 10 meters ( 30 feet ) and drive below 60 kmph ( 40 mph ) if you can’t smoothly handle the manual transmission. Increase by 5 feet look distance as you get more comfortable over several months.

    Don’t drive in traffic, park if you feel unsafe without causing problems.

    Avoid steep shopping mall parking lots and narrow spaces until you are comfortable handling the manual vehicle.

    Add wing mirrors and antenna at the edges of the vehicle corners to help visually identify the area around the vehicle.

    Best of Luck and Have Fun once you are good at it. If after 2 years you aren’t getting any results, then manual may not be the best choice for you and you may need to give it up. Automatic transmissions are now making amazing progress and reliability.

    No shame driving automatic transmission vehicles.

    It is the same/similar problem that Nokia/Maemo and Sailfish/merOS have all had.

    Some things are binary-blobs + NDAs and many things are still locked, the OSS community can only do so much before they hit the commercial roadblocks.

    We need a complete CoreBoot + OSS silicon-chips + OSS firmware + all-community / all-commercial dual production lines.

    The open-source-based company should be able to sell both the commercial locked-version and the oss-all-unlocked-version with the ability to switch infinitely between the two models.

    But the world of electronics rarely will ever work or reach that level of interoperability , repairability or recycling this way. Not for a long time maybe in some distant future.


  • Any sanitation worker, sewage diver, drain block remover, in most of the third-world countries.

    We need city drainages to be repaired, cleaned, maintained, and managed with draconian safety, extremely well-compensated, hazardpay up the wazoo workers comp and complete-healthcare all covered for life. So many workers are just abused for the lifeline work that keep a city’s arteries from getting clogged and flowing smoothly.

    I saw how Korean drain-workers do it with high-pressure water jets and incredible efficiency and knowhow talent of their vital job. I wish we didnt have the corruption that prevents this type of training, trained worker, worker pride in the essential labour that they do.

    Same goes for recycling and reducing waste. We humans don’t do nearly enough and the Top-20 major corporations that cause 80% of worldwide pollutants go unchecked and unpunished.
