achow··on CrowdStrike says it isn't to blame for Delta's flight cancellations after outage
Delta's IT department is in for tough times ahead, considering these cases drags on for years..

Should Delta pursue this path, Delta will have to explain.. why CrowdStrike took responsibility for its actions—swiftly, transparently, and constructively while Delta did not.. Delta would have to preserve a series of documents, including those describing its information-technology infrastructure, IT business continuity plans and its handling of outages in the past five years

achow··on Show HN: Minimalist, walkie-talkie for startups
That's for the founder to figure out. I imagine that with a 'pivot' on the scenario that the product is being built for, there would be change in its form (both hardware and software).

But this comment makes me think, why this product cannot exist as a mobile walkie-talkie app?

When "war" comes, the "army" launches the app and are plugged into the dynamic war operations, using a headset. When the war is hopefully won, everyone goes back to their peace time apps - Email, Slack...

> This product might work to coordinate between a bunch of sales groups at an expo or something where quick, instant communication is needed

You nailed it.

Initially I was taken in by the novelty of the idea, but when I started seeing features like Recorded Voice, Figma Integrations etc.. I quickly back tracked.

If this works, it would work for a very focussed scenario where instant communication for a short duration/event is required.

Maybe for things like "ship war rooms" for product launches, or during holiday sale event for e-commerce websites?

achow··on East Coast has a giant offshore freshwater aquifer
It is not about directly tapping into the rainwater collection, but managing the rainwater run off into ocean.

'Watersheds' are meant for that, and development of that is a serious endevor.

When rain falls on dry ground, some of the water soaks in, or infiltrates the soil. Some water that infiltrates will remain in the shallow soil layer, where it will gradually move downhill, through the soil, and eventually enters the stream by seepage into the stream bank. Some of the water may infiltrate much deeper, recharging groundwater aquifers.

achow··on East Coast has a giant offshore freshwater aquifer
USA annual rainfall = 7000 Billion Cubic Meter [1]

Annual rain water runoff = 2100 Billion Cubic Meter. As per source runoff could be between 10% to 50%, taking 30% as a value [2]

USA annual consumption = 445 Billion Cubic Meter [3]

So, looks like one has to harvest 20-25% of the rainwater to be self sufficient (without tapping into ANY of the current source of water.)

achow··on 'Supercharger on wheels' brings fast charging to you
China is propelling its electric truck market by embracing battery swapping.

In 2022, China sold 36,000 electric trucks, 91% of the global total..support for battery swapping is playing a key role.

With plug-in charging, it usually takes 40 minutes with DC fast charging or several hours via regular charging to recharge an electric truck. In contrast, battery swapping only takes 3–6 minutes.

That's the general idea behind series plug-in hybrid electric vehicles (PHEVs).

..Gasoline engine acts solely as a generator to recharge the battery, but can't mechanically power the wheels (known as "series hybrids"). Example: BMW i3..

That [picture of employee] wasn’t taken with a Polaroid with a flash.

Not worthwhile for a forger (unless from a Hollywood movie) to go extra mile for. There is some lesson there for a budding forensic investigator.

> Humans are more partial to talking than writing.

Is it so?

Speaking most of the time is for short exchange of information (pleasantries to essential information exchanges).

I prefer writing for long in-depth thought exchanges (whether by emails, blogs etc.)

In many cultures - European or Asian, people are not very loquacious in everyday life.

achow··on Ultra-high density battery vests give next-gen soldiers twice the energy
Beyond high-powered wearables, Amprius' battery tech has drawn interest from the electric aviation, satellite and drone industries ..the company does mention the EV sector as a future market, estimating an EPA range boost from 310 miles (500 km) to 547 miles (880 km) from applying its silicon-anode cells to a Tesla Model 3 battery pack.

Sounds like rechargeable battery tech.
