Hi All, since our last posting my cofounder and I have revamped our messaging and the product to be easier to understand and use. We would appreciate it if you'd give it a whirl and tell us how you liked it.
I have a Pinephone, and I can tell I've been really conditioned by Androids flow. Haven't quite figured out the UI yet, but I'm going to put KDE on it and see if my desktop muscle memory helps things.
The hardware is a bit slow, but man is it fun to have Linux in my pocket:)
I'm hoping you can develop your own "ROM" for it, I wouldn't mind making everything like blocks to reduce GUI load if that's a thing. Like the Windows Phone UI, just my opinion. It's also on my wish list to do i3-wm on it so can get some ram back in desktop mode.
omg that's literally it haha, at least the i3wm part wow. It's funny too seeing it you're like hmmm but if you had a simple button toggle to use it as a phone or dock... man that's great.
It's easy to charge less when you do not develop any software and use software developed by Purism. This is not an entirely fair price in my view. $10 donation to developers per purchase does not cut it. Also, higher specs definitely must be more expensive.
True. I think the issue is that for a platform like this to survive it will need community developers. Idk how much purism software they use or what they lend from pureOS but Pine64 has distros and projects like kde throwing themselves behind the idea with their mobile variants and probably contributing upstream. They also all help advertise. This is great especially when in the early stages it generally isn't purchased to replace a main phone.
Pinephone's pricepoint allows for people to get it on the side to tinker with, develop for it, etc and people that get it at that price don't really care too much bout the occasional bit of lag or glitch.
Additionally something like a better camera on the librem to account for the price doesn't appeal to a lot of people if they have to wait for drivers for it.
I also think pine64 has more people working remotely from all over the place and is registered in hong kong or malaysia since recently whilst purism with lots of remote stuff going on also has staff in san francisco and pays more taxes there? Correct me if i'm wrong tho.
This algorithm basically works when the number of elements to compute the median for is at least as large as the true median, and you've a fairly normal distribution of element values.
To get a rough idea of the numbers if this was a rail gun and accelerating linearly:
1G is 32 feet/second
32 feet /second is ~22 mph
They're accelerating to 5000mph so they need to crush things at 1G for ~230 second or just under 4 minutes.
If I understand correctly, this would hold for angular acceleration too, since they'd just release at some point.
Can someone correct me if I'm wrong?
Take a 200 pound payload, add some rocket to it, let's say 10x the weight to be generous, then spin it in a circle 200 feet in diameter. You're looking at 18 thousand tons of force spinning it at 5000mph. So you're spinning 4 navy destroyers worth of force in a circle, which means you need a latch mechanism that can not only hold that much force, but release it at the exact moment to exit the biggest vacuum chamber ever created through a door that just opened at the right time, generating a mach 6+ shock wave at about 0 meters distance from the door and somehow not destroying it in the process. I don't know that it is impossible, but it is highly improbable. They'd probably have a burst disk rather than a door, because that would let you use the capsule as a bullet to penetrate the exit.
In the article they mention the payload experiencing 10000g, so they must be planning on a circle greater than 200 feet in diameter. I can't find numbers on existing satellites, but I remember reading that rockets typically top out at 6g acceleration and figure on a 10x momentary acceleration due to vibration. To tolerate 10000g the payload being launched will need to be built like a tank, rather than the relatively light current designs. To ease that requirement you could submerge the payload in liquid, but that would decrease your usable payload accordingly.
It would be impressive if they could actually pull it off. I think it would be useful for limited applications. I have watched science fiction shows where mass accelerators could basically nuke planets without radioactive fallout. Maybe this would be something similar.
Having read "The Moon is a Harsh Mistress" a looong time ago, I have sometimes wondered why no one has ever tried to use rail guns as launch mechanisms. I vaguely remember from not so long ago that one of the criticisms was that the acceleration forces would crush any fragile parts like electronics, but is it still true that electronics can't be hardened to survive the acceleration forces? Are there other problems that make the idea of rail gun launchers simply impossible?
A rail gun would work from the moon, where there's no atmosphere. On earth, the projectile would attain its highest velocity (right as it leaves the rail gun) in the thickest part of the atmosphere (at ground level).
And just for a sense of scale, escape velocity from earth's surface--assuming no atmosphere at all--is 25,000 miles per hour. The projectile is going to tear itself apart in atmosphere at those speeds.
I don't think it can be broken down so simply. It's clear that the constitution has provisions specifically covering this (ex: 4th amendment), so the Federal courts at least have an interest in seeing the cases. As the highest law in the land, it's also pretty clear the 14th gives SOME federal oversight of violations of citizen's rights.
