the other sad reality is that on mobile, the number of people who read the tweets is arguably going to be higher than people who click to the blog, and a spam of tweets attracts attention and audience. I can't remember the study, but p

As a ham radio nerd, packet bulletin board systems should really make a comeback. They fell apart as the internet came about, but in an effort to re-invigorate the now-unused spectrum and hardware TNCs[1] all over the place, APRS[2] was cre

It was exceeding the speed limit by 3mph, I don't believe this far exceeds safe margins.

21cm was initially misleading; that's the origination of the hydrogen line at 1420MHz; by the time it reaches earth it is doppler shifted down (redshift) to 78MHz! I worked as an antenna engineer on the VLA's low-band Epoch of Rei

Trading is taxed just like capital gains, and mining as income. For small investments with few trades, it's straightforward and you can likely use a free service. Beyond a certain threshold (like 200 trades), it's probably worth u

This article is talking about squatting as an alternative to sitting, not the exercise. But to be fair, one should not skip leg day.

My experience is that government and gov't contractors have been turning their heads. The proliferation of E2E communication has been too fast to analyze and regulate with respect to WWII era regulations, similar to how cryptocurrency

This would be a crazy revenue boost for metro areas outside of rush hour, where interstates are typically 55mph zones, while the traffic collectively moves at 65-70mph; going any slower than the flow is dangerous, but it's a dilemma to

I've been listening to a CB radio and comparing it to waze during my commute, and CB radio is still arguably superior in avoiding speed traps and wrecks. Truckers use waze a lot but still always default to radio for real-time traffic i

I don't think this is completely ADS-B; comparing KSTL on airportviewer[0] with FlightRadar24[1], FR24 doesn't have any ground tracks so I wonder if their data comes elsewhere. [0] http://www.airportviewer.com/airpo

One might imagine with better technology, something like noise-detecting spread-sprectrum or automatic link establishment, along with advanced DSP filtering would be able to dodge these sorts of noise generators. But no. The noise is omnipr

Finally, the moment I've been waiting for, amateur radio on the top of hackernews. :) It's also worth mentioning we've got a lot of amateur radio satellites in orbit[0], and more coming, including a geosynchronous satellite l

I'll bet it blew up on the droneship. It was weird they didn't have an immediate confirmation; I thought they have a boat or heli within visual range for the photo.

I thought this was more of a thought experiment for galactic travel, that would make the most sense. However navigation by star triangulation is much less complicated and historically proven ever since ships were sailed. Star trackers are o

Also tangentially relevant: In amateur radio, soundcard "A"FSK (A for audio) is super popular. The most popular are the time-synchronous WSJT-X modes (JT65, JT9, FT8, etc). It's super fascinating from a technical robustness p

It is an issue, because as your finger is making its way to tap "Back" or "Done" the notification pops under it. It's like when an ad loads directly under your mouse cursor, overlaying something you want to click on

Just seeing that there's an antenna always pointed at Voyager 1, and that it's 21 BILLION miles away...that's almost 1 lightday...and it's still working. That obliterates my mind.

Try N2YO[1] or Heaven's Above.[2] You can track it yourself using the TLE, and a program like gPredict[3]. [1] http://www.n2yo.com/satellite/?s=43166 [2] http://www.heavens-above.com/PassSummary.aspx

Better yet, if supermarkets would bundle produce and meats into ready-to-prepare packages to compete with meal delivery. The one reason why I still buy meal delivery is because I hate wasting food and figuring out what to make. I don't
