I've been told that acceptable software margins are around 75%. Hardware focused yields closer to 20%-40%. Hence why there is such a strong push towards software-only.

Taxis in Australia, like many other places, used to abuse their customers. Uber truly made a difference; these days, Uber may represent questionable value in Australia, but at the very minimum they managed to change the behaviour of an entire industry, which is a huge positive.

Have worked at both, Airbus pays worse but has a much better engineering culture. Also arguably, because of the location(s) the quality of the engineers is quite high despite the pay as they can afford a pretty good lifestyle.

Airbus also functions very much like a quasi governmental institution in many parts, so there's less interest in squeezing everything to death to save money.

Finally, Airbus generally has a KISS mindset, and are very conservative w.r.t change in engineering practice and tooling. When I was there we spent way, way, way, way, way more time testing than writing software - and the software was written in a way that any software engineer could walk off the street and understand it.

Oh, and quite low levels of outsourcing in critical software - they save that for things that don't have people's lives on the line.

Our connectivity to mars is on the order of 12kbps, presumably better for the moon.

My other question would be whether this is due to the need to radiation harden stuff? We were developing for what effectively was equivalent to an arduino in terms of processing power due to the need for radiation hardening (and other legacy / slow moving reasons).

They probably do this because they don't want anything committed to text. It still doesn't excuse it, but yeah, they're doing that intentionally.

At a minimum they should say "this is not something you've done wrong".

The problem at least in France is that prospective employers will demand your pay slips from your previous job. If you are early in your career, they will use this to depress your wages as much as possible, making arguments like "well, we can't just give you a 40% uplift". So if your first employer screws you, the ones that follow can as well.

Personally, I would just forge one with a much higher pay level - but most people who play by the rules get screwed royally.

The US knew when <X> satellite imagery company's satellites were going to go overhead at some US base, waited for the image to be taken and then moved all its aircraft before a missile attack recently by Iran (or Iran proxies).

They know 100% who is buying what imagery, and when the satellites will be overhead.

There is 0% chance that this is a mistake. I wouldn't be surprised if the US can OK or not OK the images that make their way to Google Maps - in France, every government site gets censored before it makes its way to Google Maps.

I now have ads on my expensive Samsung. Teaches me right for not heeding the advice and getting as dumb a TV as possible.

I should not need to run a PiHole to deal with this.

They're being rightly trashed because it's a SEO tactic and nothing more. Between the preamble ranking them higher and Adsense requiring "substance" in order to monetise the page, there is a systematic issue that's leading to what is essentially useless information to what I would say is the majority of people.

They're very welcome to write their life story, but I bet if google changed their algorithm slightly you'd see it disappear - and I'd say that would be a good thing.

Crypto AG 6 years ago

Typical American companies aren't controlled by the CIA or other government agencies.

Unless the CIA has any interest in them, in which they get pwned pretty quickly.

Crypto AG 6 years ago

So can we assume that companies touched by In-Q-Tel are compromised to the same level as Crypto AG was? I'd like to collate a list.

Lego ISS 7 years ago

There is a space shuttle lego set in existence that is big enough for that. It is absolutely massive - and at that scale, I think the ISS would be absolutely unwieldy.
