  • This device attaches to a car’s tailpipe, capturing heat and converting it into usable electricity. The researchers’ innovative system includes a semiconductor made of bismuth-telluride and uses heat exchangers—similar to those found in air conditioners—to capture heat from vehicle exhaust pipelines efficiently.

    Basically, slap Peltier modules on the exhaust pipe. This ain’t gonna do much. We can invent a thousand applications for Peltier modules, until there is a massive technology breakthrough in terms of semi-condutor materials, it’s kinda pointless.

    Reusing heat energy from exhaust is what turbos are doing for 120 years now.






  • Take the time to properly understand Linux file ownership and permission. Permission will be the cause of many issues you will encounter in you self-hosting journey on Linux. Make sure you know the basics of chmod (change permission) and chown (change ownership), Linux users and groups. This will save you some head-scratching, but don’t worry, you will learn by doing !

    Remember that, if you setup everything right, especially with docker, running as root / with sudo is not required for any of the services you may want to run.


  • Men need to be feminists! It requires education, it’s sometimes hard to recognize the abuses when you are not a direct victim.

    In the case of rape… this, I can’t explain… How would some of the perps during this trial just acted (pretended) like they didn’t know they were rapping this woman! This is just beyond my comprehension. But it’s a fact, we have to face it. This people exist and we seriously have to do something about it.
