I think the exercise of saying let's legitimately try to build something vs buy, is a great place to start. It will help determine what you need in an off the shelf solution, while also serving as a useful pricing target. If the buy so

commercial air travel is all about critical maintenance. Add it to the checklist and move on. Feels like the article pandering to that y2k nostalgia.

my guess is they will buy carbon offsets to cover manufacturing energy and transportation costs, a system which has its own shortcomings and critiques.

I recall reading a similar thing, taxes aren't fun, but you could always sell the car, and pocket the extra. It's just a matter of winning something by chance and taking issue as though it was something deserved.

I bet the person in Oprah's audience who doesn't drive when she gave everyone cars was super justified in being angry that Oprah just assumed she'd want a car with inherent resale value.

is the contract public? i would like to see what contingency is in place if Boom fails to deliver. Or more to the point, is this more PR to make AA appear to be forward looking, and bolster Boom's reputation with a deal that will never

computer science imo somewhat gets the highest level of scrutiny when it comes to reproducibility simply because so many people can, in theory, reproduce an experiment without any special expertise. this cannot be said for many other scienc

I wish they had data on the estimated cost to build and operate. Best i can guess is that $11M might get them 200Megawatt/hours -> $0.055 per watt hour which would be cheaper than any chemical battery based energy storage, albeit at

ultra low profile sedans and rotary engines are the most evolved cars, so why do we have trucks? or more on point, road bikes are more efficient than mountain bikes. The monolithic view that a bike is about putting energy in and getting fo

for synthetic data generation, what methods are they using to sample data from the distribution? What assumptions about the distribution are being made? Does it model correlations between sample attributes that could adversely effect some M

In my opinion it's a great deal more complex than: "you can just turn off the features". To me "lack-of-a-feature" is not in itself a feature of the device or platform, rather a feature of the company who makes the

i agree, docker added version control, online repository, with management, and search they also fixed some of the networking headaches in lxc. Prior to developing containerd docker was based on lxc containers.

i've been saying this for some time in the US and think it is similar to the reasons we cannot build high speed rail here. Too many points of opposition for a not immediate and obvious benefit (namely lower energy prices, and fewer neg

was kind of hoping for a more analytical take, comparing their efficiency to the newish slate of battery powered personal heaters, or older iron-oxide single use heaters. My guess is the newer electronic devices allow for more consistent he

yeah for first 10000 digits there is about a 2%-5% chance (around 20%-5% for first 2k, then falls below 2% for remaining 2/3s) of selecting one that doesn't work. obviously picking something like 1111, 2222, ... won't work ei

Is the original poster sure the extra size wasn't to accommodate a 2.5" or 3.5" for testing purposes. There doesn't appear to be a physical HDD. In the 2nd prototype picture (not much for scale) it looks like a board wit

Correct, but I think the general escalation of security in airports which caught Richard Reid, was a direct response to 9/11 . Either Way, it is still mainly security theater to make passengers less apprehensive about taking what is st

For some reason they run all their tests single threaded. Seems like parallelism is where all computing hardware is inevitably going. I also wish they had run time comparisons to more recent matrix sketching and multiplication method such a

I've always interpreted it as running code directly on the processor with no OS. I made a "baremetal" bitcoin miner for the original raspberrypi, until it burned up the chip(and i learned why OSes are important). I guess it&#
