The noise pitch of a blade cutting through air and its annoyance level seems to be proportional to the blade's size: Anecdotally, 40mm and 60mm server fans are annoying as fuck compared to 120&#x…

no, they'll just turn it off, in the entire history of geostationary telecom satellites nobody has launched one with enough reserve delta-V/propellant to deorbit itself. To go from a 36,000 …

fun satellite thing: there's actually a LOT of old geostationary orbit telecom satellites which are still alive for command and control, and their transponders still work, but they're out of…

As cool as restoring the power supplies in their original condition is, it might be a lot easier at least temporarily to replace them with modern 5V and 12V units. Also a great deal less damage risk t…

I wouldn't say that India is a "major player" in the satellite launch market yet, considering the reliability record of its rockets: https://en.wikipedia.org/wiki/G…

If we're building space elevators, we could just cover the uninhabited desert parts of libya and algeria with hundreds of square km of photovoltaics...

does anyone remember pbase.com for free photo gallery hosting, in around 2002? apparently it still exists with its same basic but functional UI.

RF/microwave engineer here: It would basically be a giant death ray in space, pushing that amount of energy through the air via microwave or laser is scary as shit. https://en.wikipedi…

$499!?!?! For $130 I can buy two really good quality 1080p dashcams and two 16GB microSDHC cards (I know, not the intended function of this...) and mount one facing forward and one to the rear.

Grocery store chicken in North America has no flavor or texture because of the speed it's "grown" in factory farms. Almost to the point where a fried chicken breast is like a mass of de…

As much as I enjoy Indian vegetarian food, as a person that does eat meat, there are also a bewildering variety of dishes possible with the same spices and ingredients with meat added. One example i…

Any major ISP with clue is at least checking SPF, DMARC and DKIM scores on its incoming edge smtpd that talks to the world. How they use the scoring and results for spam filtering varies widely.

Not really bullshit if you find the right hosting company. There's shitty $200/mo single server colo options, and less shitty ones. In my experience it comes down to personally knowing the p…

On the receiving side: Ensure that your world-facing port 25 smtpd is properly pipelining all incoming emails through openDKIM so that their headers are tagged with openDKIM validation or lack thereof…
