I have an ASUS motherboard and recently went through the process of updating the BIOS. One of the things worth nothing is that it is not safe to just get the latest version and try to run EZ-flash. Some of the updates will update EZ-flash as well and those become required for installing later updates.

The download page actually has release notes which specify when a certain BIOS is required, but you basically have to read back through all of them to figure out which ones to install.


Similarly, I broke idrac on a Dell sever because I did not follow the proper upgrade path.

I just assumed that the latest bios was good and the server happily bricked itsefl


the newer (8+) iDRAC's are nice now that you can point them at downloads.dell.com and it will figure out the updates for you


The annoying thing about the release notes is whether buying new or used, the BIOS is usually wildly out of date, so you end up in an unwinnable scenario.


I also recall some IBM xservers had specific revisions to be at to flash forward.


It's a music live-coding environment that is part of the befunge family of (obfuscated) languages.


Creator here. I just updated the README and name for this project since it is the legacy implementation. I started the new implementation in Rust earlier this year.

If you're interested in seeing it in action, here's a recent video (there are more on my youtube page): https://www.youtube.com/watch?v=qeseWGmcIbY


Could you say something about the switch from Haskell to Rust? Was it motivated by performance? or type system complexity? or something else?


Honestly, I was just looking to learn Rust and this seemed like a reasonable project for it. It's small enough that I could conceivably rewrite it in a couple of months and the stakes were low if it didn't work out.

Mostly, I'm just sticking with the Rust implementation now because it has a couple of new features that I wanted. Also, it should theoretically (I have not tested) be able to run on other OSes, since it is built around JACK instead of ALSA.


It looks extremely interesting! Is there any sort of documentation, like a quick introduction, tutorial or reference? I found the Wikipedia page about Befunge and I just don't get, how this transforms into sound in Noisefunge...


If you divide the total revenue by the number of HR employees, you will also get a much larger number. (Total revenue / total number of employees) will always be less than (total revenue / subset of employees).

This is not a very good metric.


In a company like Facebook, who is directly responsible for the revenue? And who is working support roles?

If you laid off 90% of HR, how will that affect revenue? What about laying off 90% of the engineers?


HR, Accounting, etc. aren't directly revenue-producing. You could make a good argument that Sales headcount should be included, though.


Divide by number of product managers then, even higher per headcount.


If you don't pay and they expose your data to the world, doesn't that mean you can effectively get it back without paying?


What makes you think the data is complete and/or hasn't been poisoned?


What if the data is highly proprietary and now all your competitors have access?


There are legal avenues you can use for that. the bigger danger (for most cases at least) is raised by your sibling, you can't trust the data anymore to be the same either innocently or maliciously.


Zuckerberg never had to interview at Facebook.


How is gold created out of the collision of stars composed of neutrons?


Neutronium (degenerate neutron fluid) is only stable at immense pressure.

Relieve that pressure -- by flinging bits into space in a collision or explosion -- and it reverts to neutrons + protons + electrons + antineutrinos, forming first ultramassive nuclei, which rapidly decay to stable elements, many being heavy elements well above iron in atomic number.

The nuclei mar be formed by r-capture (rapid capture), or perhaps devolve from dense neutronium clumps.

>How is gold created out of the collision of stars composed of neutrons?

They are composed predominantly out of neutrons. Some percentage of their composition is still electrons and assorted atomic nuclei, which is a non-trivial amount of matter considering the common range of density they tend to have.

I would imagine all kinds of interesting(strange?) interactions take place when such dense and energetic objects collide.


If you smash proton and neutron clumps the size of stars together you get fragments that are gold-sized.


That makes a little more sense. The original quote suggests that a single very large lump of gold was created, not a very large number of separate gold atoms.

This raises the question of why gold tends to be found near other gold on Earth.


> This raises the question of why gold tends to be found near other gold on Earth.

When you spin a combination of stuff that is "loose enough" at sufficient speeds, the centrifugal force acts on the constituent masses differently. As a result similar masses coalesce.

This is the same principle used to separate and concentrate (enrich) all kinds of stuff in centrifuges.


Is there an answer to that question? And, why is the distribution of matter not random? Maybe some sort of gravitational grouping? (eg earth's iron core, centrifugal enrichment of uranium). Or affinity for some orientation relative to field states, magnetism/diamagnetism etc.?

Like attracts?


As I understand it, the distribution was decided when the earth was still hot. So the mechanics you're interested in are those of high-temperature solutions containing liquid gold, which I don't understand that much. There's other interesting phenomena too, like gold frequently occurs in quartz rocks[0].

I'm not a geologist at all, but when you freeze soda you tend to get water ice infused with veins of high-sugar soda concentrate. I wouldn't be surprised if similar mechanisms tend to lump matter with similar melting points together in molten rock.


Deep in the earth matter tends to clump together by density, just as oil separates from water due to density. There is still some dynamism though so temporary mixing does occur.

Gold at earth's surface tends to be found in deposits where water with gold particles in it was flowing through a crack for an extended period of time.

Over time some of the gold is deposited on the sides of the crack, essentially concentrating it through evaporation and deposition.

These cracks then become what miners call 'veins'. Other metals and minerals have similar stories.

TLDR: water from deep in the earth carries gold particles upward. Cracks form consistent flows which concentrate deposits over time.


Materials separate by MACROSCOPIC density. However, heavy elements can be chemically bound in light materials. Uranium, for example, is highly concentrated in the Earth's crust compared to the mantle.


Good point, although I believe gold is usually found in its elemental form (although sometimes alloyed with other metals).

I didn't know that fact about U, thanks.


Gold is a siderophile element, chemically favoring to bind with iron metal, and preferentially went into the Earth's iron core when the planet differentiated.

This is why mining asteroids for siderophiles (like gold, but also platinum group elements) has been a staple of space advocacy.

Works every time.


Biosphere 2 was meant as a self-sustaining ecosystem capable of supporting human life. It wasn't entirely successful, but was along the lines of what you described.

https://en.wikipedia.org/wiki/Biosphere_2


Biosphere was an interesting experiment, but very different from what I had in mind. It relied on a huge up-front engineering effort, orders of magnitude more than what would be realistic on Mars. What I had in mind was a colonization effort in the desert starting with what you could realistically carry on a spacecraft, i.e. a few shipping containers (even that is being pretty generous) and then no outside contact for two years (at a minimum).


I don't believe it is accurate to say that nothing happened in the Sony case. They were sued by state governments, the FTC, and faced class action lawsuits. They also incurred the cost of recalling the affected CDs.
