Stories recounting cruel physical and sexual abuse are only a google search away. Of thousands of children being disappeared. Of being woken in the middle of the night to dig graves.
Because time in the real world uses leap seconds. The time businesses open and close. The times reported in news articles. And so on. What facebook wants is for all of them to stop using leap seconds so facebook’s infrastructure is simpler
The lasers they use are extremely specialized, since they have to deliver outrageous amounts of power for a very short period of time. Advancements in normal lasers may not be of much use here
Edit: Wow, looks like they have improved considerably
That’s assuming they ever even make it to net positive energy output. The article carefully avoids mentioning that the lasers they use are wildly inefficient. It is very hard to break even when you lose 90% of your input power right at the start
In most of the US they aren’t common. Outside of that debacle in Texas, I can’t recall any rolling blackouts in the US from lack of supply. The rarity is quite likely why that event made international news and got so many people around the country talking about it
This comment would be more compelling if it gave any hint about what aspect of the tooling the author didn’t understand or what they should be doing differently.
> In the modern world, the demand seems to be that every tool be perfectly safe in every situation no matter what you do
The problem is that there is such a huge number of tools in widespread use that each one causing even a few security vulnerabilities means that the ecosystem overall is constantly vulnerable
Adding features to existing software is much cheaper than writing entirely new software (not to mention the cost to switch!) At the same time, new features in low level software can unlock substantial value. Say a new API that speeds up your app by 1% or cuts down on further development time by a small fraction.
Email addresses aren’t usually secret though. If an employer happens to know the personal emails of a large fraction of its workers, it isn’t going to be meaningfully slowed down by a hash. 1M addresses * 1 second/address = ~12 days (and in practice a lot less since hashing is nearly trivial to parallelize)
A reasonable rule in both cases is to prosecute crimes when other people are being exposed to harm. Failing to intervene to stop scams or fraudulent behavior seems like a clear case that should be stopped, and ideally sooner rather than later
In other words, you paid $17.30 for $27 of goods and services ($19.50 if the driver avoided the return trip). Which means someone was losing money on the deal and the price is unlikely to be sustainable long term
They’re paying you to get real people to sign up with the intention of using the service. If you sign up a bunch of sock puppet accounts, or pay a bunch of people to sign up for a month and then cancel, then you aren’t holding up your part of the (perhaps unwritten) deal
If a vehicle is approaching you head on, isn’t it much safer to assume they aren’t turning? You’ll usually be wrong, but if you are right it could avoid a head on collision
It has nothing to do with the quality of the undergrad degrees. Even most top tier programs suggest going somewhere else for grad school because each department has its own research culture and it is good to pick up on more than one
There's tons more that we can be doing now to reduce transportation emissions. Investments in transit and bikes. Locating housing closer to jobs. Blocking highway widening efforts. All other efforts to reduce vehicle miles traveled. Ignoring all those on the belief that it is "tractable" to eventually reach net-zero without them, is exactly the complacency I was talking about! In other areas, reducing energy consumption is identified as a necessary and impactful way to reduce emissions in the short term, and make fully converting the grid to renewable easier in the long term. Why not here?
