So, my comment was flagged for simply stating the fact that not all police are bad people. Great, we'll done HN. As someone who lived in Baltimore City for 20 years, and was forced out due to uncontrollable crime, I can say from first

I heard that in the American desert plain, shielded by Pacific Coast mountains, the lack of wind leads to a reduced sand movement and ultimately sun-bleaching of our holes. This discoloration confuses local fauna.

It's a secondary effect. De-regulation of flight costs and routes cause airlines to cut as much "percieved unnecessary" expenses to maximize profit to the point of where they are now - bare bones staffing, ancient IT infrastr

Yeah, the reporter didn't do a very good job of reporting the entire story. I find this often with news these days - they report the "what", but so often, frustratingly not the why. Super annoying.

This is an extremely annoying read. I was hoping for a rich dataset. The USCG and Government datasets are extremely sparse - especially in polar regions. Here you have the US Healy traversing the arctic and the only data collection this tea

Maybe removing the word "in" from this headline would be more apt.

Even for something like HDPE? I did a project a while ago that was effectively a pontoon workboat. We used HDPE pontoons in lieu of stainless steel and the cost savings was about 25%. I assume that the raw materials (basically large diamete

As someone who is personally a bad idea machine, I feel qualifies to respond here. There's a lot to unpack here, but I think it boils down to being good at winnowing down a solution space - which is pretty squarely a Systems Engineerin

I assume you're asking about classical Von Neumann or ARM architectures and not something else more exotic. I think you'll want to check out a course on Computer Architecture, to understand the basic building blocks of classical c

Using a human host was just an example to show there are certainly real possible applications whe magnitudes of these units is useful. DNA-based data storage doesn't necessarily mean humane genome data - you can store any data (1) in a

by mojomark 3y ago
Meh, it was just an example. The point is that extremely dense data storage is now concievable, though perhaps not yet practical (e.g. using a "DNA drive") so this magnitude of units has it's place in the real world.

I'm not sure I understand the sarcasm (i.e. why TB/ns is an unrealistic A.) ...one gram of DNA can store up to 215 Petabytes or [215,000 Terabytes], knowing that the human being has about 600 grams of DNA [129,000,000 TB]. (1) B.)

Valid point. I like to peruse the headlines on phys.org before I go to bed for the evening, ran accross this and thought it might be of interest to HN. Write up was enough for me, but agree that they are shit for references for those that w

Yeah, "4K TV resolution" doesn't mean anything as that completely ignores viewing distance. Pixels Per Degree (PPD) is the core metric and it drives me bananas that marketing professionals continue to intentionally obfuscate

My read from the page was that this term is coupled with a temporal component - the need to think effectively on your feet. Rapidly. Unfortunately, that's not me. I'm a sit and ruminate kind of person. Oh well, no System D for me.
