badosu··on Why Facebook is losing the war on hate speech in Myanmar
> My favorite example of communism implemented in real life is a hermit / monastic retreat, a skete

There were allegedly lots of epicurean communities in the antiquities, many of those in Europe, which became monasteries.

Epicurean communes were, for all effects and purposes, communism.

I am not sure, I am not a physicist.

What I understand is that the contemporary conception is that the mass does not change.

I just presented the argument for a notion of rest mass and relative mass.

badosu··on Absolute Hot
Since E=mc^2 -> m=E/c^2.

For a moving object you could then m=(Er+Ek)/c^2, which creates the impression that the mass is variable (as the term Ek is zero when at rest and increasing with velocity), giving rise to the terms 'rest mass' and 'relativistic mass' respectively for the rest energy and total energy equations.

This interpretation is somewhat outdated but the terminology rest mass maintains its legacy. One could refer to it as the `(proper |invariant |intrinsic )?mass` instead.

The variable mass issue is then 'solved' by 'refactoring' the equation to use momentum where mass is coupled with velocity, over which the complexity of the lorentz factor is engulfed.

badosu··on LHC physicists embrace brute-force approach to particle hunt
I wonder if this is due to the success of the current models (less hidden corners), academic incentives for paper production as opposed to breakthrough work, the ever growing specificity and cost of experiments (making less sure experiments unviable) or some combination of these factors.

No hadron can achieve the speed of light. See:

Ek=mc^2/√(1−(v/c)^2)−mc^2

For v<<c you have significant discrepancies on the energy required to accelerate to a specific speed with regard to mass. I.E. Newton: Ek=(mv^2)/2

As v->c it does not matter as much, the lorentz factor is much more significant, the mass operates just as a base multiplier and sum factor.

As v->c, x->0 where Ek~1/x, i.e. tending to infinity with a division by zero when v=c.

In conclusion, the speed is the relevant factor instead of mass when near speed of light, regardless of the object being an electron or the mount Everest.

Of course, assuming the equation holds ;-)

The sun could be used as well, the problem is that the focus would be outside the solar system.
badosu··on Why Use OpenStreetMap Instead of Google Maps?
It certainly feels like it.

If it did not have that snark though, one could make the point that the data could still be 'deanonimitized'.

badosu··on East German Doping Victims Die 10 to 12 Years Earlier – psychologist
I think the concerns are more about lowering the need of the testes to produce testosterone, leading to atrophy.

Of course, it can be beneficial if you want to keep a baseline that's important for your health.

Otherwise, something that's very risky if taken in the younger years.

badosu··on Nordic Ice Skating on Thin, Black Ice in Sweden Is an Art and a Science
I don't understand, is there a way to assume you would swim in something that's not natural?

For me, in Brazil, surrounded by waterfalls and beaches it's not only common but also necessary for you to relax sometimes.

badosu··on Firefox is back. It's time to give it a try
I remember the first time I found the firebug JavaScript snippet, I could finally use a decent debugger when testing other browsers.

That was equally kind blowing to me.

badosu··on The software engineer’s guide to asserting dominance in the workplace
What if the keyboard is silent, e.g. brown switches or lighter? What is the issue in choosing the work tool you'll be using for 8+ hours daily?

And how does that make you an asshole?

Works pretty well for the gym though, I wonder if this is intended or not. ..

Gotcha, thanks!

> Except that Islamic culture drew heavily on them too, especially the Greeks.

Most of the reason Europe was able to even have access to Greek works was due to Arabic translations, in many cases the originals do not exist anymore.

While in Europe the barbarians were ravaging the remains of the Roman Empire and entering into feudalism and the 'dark ages', Hindu and Greek works were being studied and improved in the Arab world (e.g. Algebra, Algorythm words coming from Arabic works).

These later would be brought to Europe via trade with italian city states and copied by the church.

> But it's not. North America and South America are just as separate as Africa and Eurasia.

Could you clarify that? I understood that as both cases are separated by a channel (Panama vs Suez), or did you have another meaning?

Exactly, I too agree with the grandparent, but I think parent has pushed too far on the other side of the spectrum.

Saying that as a Brazilian that is astounded every time Latin America is implied to not be 'western'. I would feel offended, but I understand that is useless to me, the same thing with the term 'American'.

Let them live in their happy bubbles, it's a disadvantage of their own creation.

badosu··on Ask HN: How do I learn math/physics in my thirties?
Exactly, your mileage may vary, but my mindset has to be completely free from distractions to be productive.

The library on my uni when I was in Math undergrad did not have AC at the beggining but was the only place where I could do any work, it was extremely difficult and I am sure impacted my progress.

Of course malicious behaviour will not comply, but would at least filter the mainstream products.

badosu··on On Britain's Intellectual Decline
It's not like all channels are obligated to perform as dictated.

So, for a free, subsidized public channel, it makes a lot of sense to offer something different from the commercial crap.

I learned a lot watching public funded science divulgation material.

badosu··on Over 30? Too Old for Tech Jobs in China
Isn't this rampant on US as well though?

E.G. shallow perks as ping-pong table, snacks, videogame, beers in the office but totally disfunctional management and work-life balance.

Using the latest shiny tech just because it makes it easier to target these groups and replace the burned out ones.

I see this happening a lot on finance and consulting jobs outside of tech too:

- Offer a reasonable salary for interns/trainees (not reasonable relative to the responsibilities though)

- Promise a huge corporate salary with benefits for the ones that are able to remain more than x years

- Burn all of them out, working overtime, abusing from young inexperienced people

- Promote a couple from dozens of people to serve as an example of successful cases

- Fire or continue abusing the rest

- Rinse and repeat

In the end you acquired a couple of indoctrinated corporate zombies as well as years of cheap hours from the other ones.

Just take a look at every year's trainee program and the mind washing process from banks and corporate consultancies. Do the candidates really believe that the company needs so many trainees each year? The turnover is a feature, not a bug...

Edit: Just noticed my point is not related to your argument, and I actually agree with you.

> tl;dr People are complex and if you are trying to control minds, often your efforts can backfire.

I believe in that, but I also think you're underestimating the effectiveness of social control when done competently, which IMO is what's China's doing.

You don't need to control people's minds, just their social acceptance and livelihood guarantee.

This is a pretty interesting idea, I wonder if a consistent model of EM frequency damping with distance traveled could be built.
