"But of course, the CCP is ideologically opposed to self-representation." Don't think it's to do with ideology, just desire of a small cabal of people to have absolute power and control over a country and everyone who li

In my view, accidents aren't the main issue, it's more the disruption caused if an AV, with no human driver, encounters the 'freezing robot problem' (I.e. When traffic lights not working, with policeman directing traffic

I'd honestly just walk out if a company asks this stuff, yet the actual work is maintaining a CRUD app.

"AI is the phrase behind which magic hides and people love magic. Everything that has the aura of “humans don’t fully understand how it works in detail” will be used by charlartans, snake oil salesmen and conmen." 100% this!

How does a profitability dial work for companies like uber, which don't have the network effect monopoly that the Amazon's, Facebook's etc have? Hike prices for passengers -> passengers leave platform & switch to local

"Uber/Lyft do have a VCs-will-not-race-to-the-bottom-with-them moat, and tomorrow they might as well raise their prices to turn profitable." That's the multi billion $ question, if they hike prices to become profitable,

I presume it's because they're contracting? It's the way to cash out in software in the UK, I believe in most companies, contractors get to sidestep the HR/salary budget hierarchy, usually because the company is really d

I think other professions emphasise past experience and referrals more. That and official credentials, especially in certified professions (I.e. Medicine). That said, I think all interviews have an element of silliness to them. I know a fin

Personal experience on this. My degree (physics) was nearly completely orthogonal to my career (software engineer). But I have no doubt it helped me get not just my first job, but also subsequent ones, probably due to 'his code/te

"Non technical management - this should speak for itself. I've done it before to much regret." I wouldn't put this as a con, I've seen lots of engineers turn into terrible managers, because the skills are completely

I understand anther part is, they can't afford to have unemployment either, especially in the restive uighur and Tibet regions. Having millions of unemployed young men, without a political channel to air their grievances would surely s

I'm not sure it's easy for a software engineer to develop a model, it's quite an orthogonal skill, you need a solid grasp on mathematics and especially statistics.

Must have been really exciting time to be particle physicist in those days. SLAC & other colliders enabled a revolution in physics, culminating in the formulation & verification of the standard model - a truly unparalleled feat of s

I always understood that the Stress–energy tensor in general relativity has a momentum component, so two electrons whizzing past each other at near the speed of light would exert a stronger gravitational pull between them, in all frames of

Minor clarification. The standard model does not describe gravity. It ignores it, which is fine at LHC energies because it's orders of magnitude weaker than the other three forces. At the planck energy scale, this is no longer the case

Indeed, I've never in my career (in high level businesses, I.e. Finance, advertising) seen such a thing as a proper 'specification'. It's more the business has a high level, rough idea of a change/feature to improve

Imagine that's part of the challenge. Since python is dynamically typed/duck typed, it's hard to audit all usages of a variable. I.e. If I see a py2 string declared, how can I be 100% sure I don't break downstream comp

That's the energy scale where the force of gravity becomes strong enough to influence subatomic particle interactions. Currently, our model of nature at subatomic scales (the 'Standard Model') does not include gravity. This i

Ktor, it's working really well, only downside is limited openAPI/swagger support, i.e. Schema first or code first code/schema generation.

Kotlin, our company had recently turned into a java shop, and I was literally tempted to throw in the towel because I'm used to C# & python, so the boilerplate was really unpalatable. Then one of our team wrote a service in kotlin,

It'd have to be a really heavy planet to see obvious gravitational lensing effects (I.e. Sun size). We detect planets in other systems by seeing them pass in front of the host star, or we detect them radiating IR, or if exoplanet is re

Cool stuff. The computation side of the LHC is really impressive. For a full software trigger, you have 25 nanoseconds in which to load all the raw collision data, reconstruct 100's of particle tracks, calculate their momentum, join th

Absolutely, also worth adding the detectors also have 'minimum bias' triggers, that store a small fraction of events without applying any selection criteria. I recall this was mainly used for calibration and verifying stimulation
