I don't think Metallica is my favourite metal band.

@thor Did you know that Surf Rock is essentially Metal? Check out Dick Dale and listen to the complexity of the riffs. He was Jewish so that would explain some of the complexity.

IE Surf Rock with effects, gain and distortion made metal what it is.

@xorbit @rhempel @lupyuen It needs to be built to a standard. The standard being better than the competition, not cheaper.

"A good Embedded System should operate without issue for many years."
Exactly. That is: it should operate completely unlike the steaming pile of turd that most software on this planet has turned into. (Despite all the abstractions and CI that supposedly was going to make it all better and has completely failed to do so.)

Embedded need to be lean, simple, predictable, reliable.

@xorbit

"Embedded need to be lean, simple, predictable, reliable." --> Sadly, that should be true for all software, but was sacrificed in the 1990s or so.
Big projects back then had "memory budgets", now in most projects we don't even know how much memory is required.

~1999, I ran a building automation system in Java, with a web UI in Java, attached (JServ back then) to a Apache webserver, on RedHat Linux with a fvwm95 desktop.... On 32MB of RAM!!

@AmpBenzScientist @rhempel @lupyuen

@bonifartius @niclas @xorbit @rhempel @lupyuen It was built differently back then. The hardware for embedded systems was usually robust. I think WRT 54 routers are still working with mods. Remember JTAG and UART headers on circuit boards?

I'm not trying to revel in the past but there are certain features that should make a comeback. It just seems like modern electronics are made to turn into ewaste. The software or firmware is another issue but the hardware will usually prevent anything other than malware from making use of it.

@niclas @xorbit @AmpBenzScientist @rhempel @lupyuen
and contrary to modern stuff, old software tends to still run just fine. fvwm still works, apache still works. can't say that of most modern software.

@freemo @BernieDoesIt @jkxyz @scottsantens Poverty will lead to improved money management skills. Before I started college I bought around $400 dollars in hand tools and a laptop. It took a lot of saving up to buy but good hand tools are an investment that pay themselves off.

I still have those tools and that laptop. A Craftsman 354 piece Mechanics Tool Set and some Toshiba Satellite with an AMD C-50 "Ontario" APU.

Poverty is something that I've never been able to escape. It gets rough but I would like to think it will all pay off one day. I can only say stay sharp, say nawt. One needs every bit of leverage they can get.

@BernieDoesIt

I grew up in extreme poverty that continued into adulthood. I lived in the ghetto, on welfare in section 8 housing in a home with my grandparents, cousins, uncle, and mother all in the same small home.

Thank you for the QED though regarding your own bias.

@jkxyz @scottsantens

Interesting fact of the day: A gravitational wave, having energy, also generates its own gravitational field in addition to itself. Though this field is insanely weak.

Note this is not the same as saying a gravitational field has its own gravitational field. It is only the wave that has energy, and thus its own field. A gravitational wave only occurs when an object with a gravitational field accelerates (and orbiting another object counts as acceleration).

@icedquinn

Yes but that is to be expected from known processes already.

An orbital can have two objects in it with opposite spins, when they have the same spin they would occupy the same space and thus couldnt exist in the same orbital. Therefore an electron with the same spin as another must occupy a higher orbital than one with different spin, thus must have more energy. More energy means more gravity.

So in short one would expect flipping spin would change the gravitational field strength.

@freemo @icedquinn So this has the possibility of being useful in the future. That's pretty cool. I wonder if energy shields would benefit from amplification of this.

@DanielaKEngert @daridrea Ah this reminds of a time when some people tried to get rid of C. Nothing will replace C. Looking at Cpp after the Rust Epidemic was nauseating. Is memory really safe if it can't be accessed?

I bought a book on Rust and intended to learn the language. I made it to the part where it got into memory management and stated that it was completely unnecessary. Pure hubris. Even if the language is magical, it could make its users horrible coders in another language.

It does have beautiful syntax. The Licensing and Foundation are pretty sketchy. MISRA Cpp and MISRA C already exist so what is the point in Rust? I'm not saying that C is without faults, something about the power of assembly with the usability of assembly. I despise Cpp unless it's embedded, it became bloated.

Rust has numerous faults and the heavy handed foundation might be its downfall. Hopefully it will escape the grips of the corporate overlords and evolve freely. I hope to see it again someday but in better condition.

@thor @alci That's not called penetration testing? That sounds a lot like penetration testing.

@rhempel @xorbit @lupyuen Embedded Systems need to evolve for product sales. A good Embedded System should operate without issue for many years.

I didn't see EEs or CS majors doing anything useful for embedded systems. It was only a group of hackers that dared to mess with the dark arts.

@freemo Don't worry, there will be more horrifying STIs coming soon. Perhaps some are already spreading silently. Maybe it will be similar to The Crazies but more subtle and slower.

Data is beautiful.

In the 60s this would have been a starving lion. Scientists are slacking these days!

@lupyuen Wow. Responses like that explains why the industry looks the way it does.

πŸ€” "Why would any sane CS Grad switch to Engineering to do Systems? ... I don't get how working with obsolete machines is anymore useful to learning how modern computers work than actually working on modern machines"
