Are you saying that it’s impossible for the lack of persistence or focus to be problematic in someone’s life?

This happened to me a couple months ago. My Facebook account was disabled, as well as my instagram account, since it was connected to the Facebook account. No explanation, and no possibility for appeal. I had the account since it was only a

I work at NASA and I review SBIR proposals from time to time. Most proposals are pretty mediocre. Some are physically impossible. Coherent writing and formatting helps. Clearly explaining what your tech is and what advantages it could offer

Are you suggesting 85 year olds typically have more wisdom and are less easily fooled by things?

IPv4 + all the other stuff you need to actually make it work in the real world actually seems more complicated than IPv6 to me. Maybe they’re comparing the minimal implementation on a home network. But even then I’m not sure the claim holds

Project managers are right until proven wrong, and engineers are wrong until proven right.

What makes you think an LLM is internally consistent?

I guess if one color pixel was significantly less efficient, and that color was also overrepresented on the display, then MAYBE changing to grayscale would require slightly less power to display the same intensity. But I don’t think that co

Every single example given under “In Chinese, affirmation is often compiled through negation:” sounds completely natural to me, as a midwestern American English speaker. However the direct affirmations are also acceptable. Maybe the differe

Option 1 isn’t really an option, unfortunately. There are no viable single launch options using it. So it’s really SLS x 2. But building and launching one SLS at a time is almost too much as it is. If that’s the only option, I think Artemis

I think we use the same PPBE process at NASA. Many of the systems and procedures that NASA uses are are defense-derived. If it's anything like what we do, then it's a total mess and we mostly just go through the motions with it, k

I'm a NASA civil servant and I'm regularly involved with SBIR contracts. While there are definite wins that make the SBIR program feel totally worth it, those are probably exception. A big factor, however, is that much the tech NA

As a NASA employee, I think this is extremely true. I would bet most of the second group doesn’t or even comprehend that they’re doing it.

NASA was originally formed as NACA to research aeronautics technology and help advance our uncompetitive nascent aerospace industry. Building spacecraft and space transportation systems like the shuttle came later and is a very different t

The mars probe unit problem was mismatched between different software programs. One was telemetry reported by the spacecraft to the ground, the other was software on the ground that used this telemetry to perform calculations that reported

I work at NASA in tech development and I have found that we have a lot of poor quality support service contracts. The faceless contracting companies supply staff that technically fill roles like providing IT support services, or supporting

Well, there still isn't. It's not really a new line, just an indirect connection via existing high speed lines that takes over 8 hours. I don't think that's gonna be very competitive with air travel which takes less than

They stated a hypothesis and asked if anyone had collected data that could support it. You responded by asking that person if they have any data. Perhaps you scored poorly on reading comprehension.

And that’s not really the same thing. Did someone invent the LED bulb in 1920 and that cartel crushed it? Not really. In reality, the biggest problem was they had no incentive to invest in new lighting technology research, although they had

So far it has definitely saved me a lot of time googling api docs and stackoverflow for me. Anything that requires applying things in novel ways that doesn’t have lots of examples out there already seems to be completely beyond it. Also, it

Are you saying that the universe cannot be represented by mathematics? I imagine you could use that argument to shoot down pretty much any explanation.

Probably the same reason the Space Shuttle wasn't cancelled even through pretty early on it was clear that it didn't make sense. Upper management decisions are seldom made for good technical reasons.

I used to see it more like that. But the reality is that one of those candidates is going to get elected whether you vote or not. So not voting is basically just letting other people decide for you. Which is rational if you genuinely believ

As someone who works for the nasa, I’m not so sure. You’d be surprised how much stuff gets randomly thrown away to save space. And it’s going to get worse I now that paper files are disappearing. I wanted some info and data from a test we d

That’s a good point. Imagine if an LLM could only read, speak, and hear at the same speed as a human. How long would training a model take? We can make them read digital media really quickly, but we can’t really accelerate its interactions

I think the FAA generally performs audits, not inspections. They usually make sure the paperwork is in order. Less likely that they make sure the paperwork is actually correct, and vastly less likely that they make sure that the actual thin

Technically it was in the fan disc, and not a turbine blade. And while there was a defect, a big part of the problem was that an inspector most likely missed a crack during overhaul. The crack was present at a previous inspection, which the

The radiators don’t have to increase in size really. If it’s more efficient you don’t have to reject as much heat. But definitely a large increase in complexity as Stirling engines are mechanical devices and thermoelectrics are solid-state.
