But you're actually talking about applications that use Oracle as a base, not Oracle database itself. For example here in my company we create PostgreSQL-based applications on a daily basis, we create complex analysis tools, BI, reports, graphs and etc, everything our customers may need we develop and we do not depend on any tool that requires the use of Oracle.
Honest question. Why PostgreSQL is not it an option? It is used extensively in my company serving millions of people (government) and works well, I do not remember having had any problems with it.
My humble opinion is that the experiment of the Germans is flawed. If I understood correctly they put at most 2 watts of power in the device (then tested with 50 watts but also using an attenuator to neutralize them), when I remember that the original idea suggests the use of several kilowatts to have the desired result, 2 watts would not even be sufficient to differentiate the effect caused by the device from the background noise (as another commentator correctly pointed out).
My guess is that the EM drive is scraping on some physical effect that we still do not understand and we would need more experimentation to try to maximize the observed effect so far and see what happens.
I was thinking the same thing. I remember well that the idea was to put kilowatts of power on the device for it to work, not mere 5 watts (if that were so even I could do this experience at home). And there are ways to deny interference from the Earth's magnetic field to see if it's the reason for torque, I suppose these scientists are (or should be) testing this now.
Funny thought... What would happen to a can of beer if I put it inside that "fridge" (assuming of course that the refrigerator was large enough for this)?
This.... Oh boy, this. I develop primarily in Java these days, mind you. And so I know it's possible to make lean applications using Java (an entire multi-user government system using 80MB of RAM? No problem). And knowing this I get to cry with anger when I see freaks using gigabytes of RAM to do more or less the same fucking job, simply because they throw everything and the kitchen sink over (frameworks) the thing to have ONE function that they could simply do themselves.
The part that I find funny is that it is simple to test the flat Earth theory... If the Earth is flat, then it must have edges right? It would be enough for one of these guys to get a boat and then navigate to find one of those edges. Or would they have some "fail-safe" theory to explain how a supposed flat Earth would have no edges?
well if I were a time traveler I would never show up at a "party for time travelers". Just think about the problems I would have as soon as I proved to be a time traveler, at minimum I would end up locked in some secret government facility or worse.
It looks like a little subway to me, which makes sense. You do not need to dig a wide tunnel if you use a smaller vehicle with circular section instead of a subway train, and take all your passengers sitting or semi-lying in several smaller vehicles rather than just a large one (the train). And you can dig a narrow tunnel faster than a wide one.
What I meant in my question is what would be the difference because the liquid oxygen/hydrogen is already something condensed and at very low temperatures. Or is it possible to cool and condense it even more than is normally used?
I fail to see any difference between "load it up with propellant at super-cold temperatures to shrink its size" and "load it up with liquid hydrogen and liquid oxygen", where, as far as I know, manned rockets have been loaded that way since the Apollo missions.
It seems that my comment attracted the wrath of a bunch of people who do not like to be contradicted and who have mod points. I do not give a shit about them.
Interesting. but I think I figured something to solve at least this part of the issue: Using a "full duplex" connection, i.e. one entangled pair to receive and another pair to transmit, where you know that you should not interfere with your receiver particle so if it changes color it's because the other scientist actions (Of course this still leaves open the question of how to read the color without the own reading causing the color change)
Nobody can tell in a meaningful way who shook his marble first. Depending on the velocity of the observer, it could be either one of you who "instantly" programmed the other marble to assume the opposite color. (This is the part that most people forget when describing the spooky instantaneous, FTL action at a distance.)
I also thought about this problem... It would be necessary to develop some means of identifying when the marble changed color because of you (error correction? better control of local conditions of the container?) or because of the other scientist.
Remember once more, none of you had any control over what color your marble turned.
That's the point I'd like to research/try more: Try to find means to set the color of the marble without breaking the entanglement, if this is not currently possible.
And you are sure about that? I ask because I'm kind of tired of seeing answers given by "fanatics" about a subject that in fact no one is really sure how it really works (not even me, so I try to keep an open mind about the possible explanations)... If I had a laboratory I would now be trying to find out if I can set properties of the particle (spin, charge, etc) without breaking the entanglement.
Some time ago I read a possible explanation for the entanglement that makes sense even though it leaves physicists ripping out their hair... That perhaps two entangled particles are, somehow, actually the same particle existing in two places at the same time.
Actual physicists, please correct me if I'm wrong:
Yes it apparently is faster than light in a vacuum, but it doesn't seem to matter. The change in spin happens instantaneously at both places, but since you can't deliberately change the spin yourself, merely observe it, no information is actually propagated. Thus you're not transmitting anything faster than light, and the universe therefore doesn't explode.
Are you sure about this part? if I had a laboratory for that, that's what I'd be trying to figure out how to do right now (and also how to read the state without destroying the entanglement in the process or causing an unwanted state change).
Adendum: It's very important to note in my example above that the two scientists, the one on Earth and the one in Alpha Centauri, do not know in advance which color one of them will choose to set on their marble. What they know is that if one of them measures the color of the marble and gets red it will be because the other scientist must have set his marble to red (because of entanglement), the only problem in the idea is if it is possible to measure the color of the marble without the measurement itself causing the color change.

Nah, I believe the answer is more complicated than "explodes", perhaps something XKCD style. Maybe "Bose-Einsten beer condensate"? :^)

None of those Flat Earthers were shouting Allahu akbar and beheading infidels.
Yet.

I was thinking the same thing after remembering how the dragon's escape system works
Thanks, your reply is much more useful than the reply of that "sjbe" moron.
What I meant in my question is what would be the difference because the liquid oxygen/hydrogen is already something condensed and at very low temperatures. Or is it possible to cool and condense it even more than is normally used?
The gif is very interesting (and at least for me it seems that the abort system worked correctly and the capsule came out unscathed)
I fail to see any difference between "load it up with propellant at super-cold temperatures to shrink its size" and "load it up with liquid hydrogen and liquid oxygen", where, as far as I know, manned rockets have been loaded that way since the Apollo missions.
My reply above don't show on the general discussion ( only on my personal log), I would like to know why.
This one. I'm not a "north korea friend", but a US promise is not worth shit.
