41) Message boards : Number crunching : Samsung phone batteries (Message 1773276)
Posted 22 Mar 2016 by Profile SciManStevProject Donor
I also have a Note 4, although I don't crunch with it. What i did read over the last year, is the lithium batteries don't mind being charged and discharged, but become stressed plugged in all the time. This doesn't seem to happen with laptop batteries, but I have destroyed several camera and two way radio batteries just leaving them plugged in for a week. On the other hand, I have a DeWalt screw gun, and both of it's power packs can be plugged in for years without damage. The articles I have read, focus on phone batteries, and the firmware inside them. The firmware is supposed to limit over charging, but may not always work. From my destruction of the camera and radio batteries, I would say that the articles I have read were correct. Now, I charge the batteries, and then let them sit until needed, and I have had no further problems. I have replaced my wireless home phone batteries numerous times, as I expect to get about 6 months out of them.

For my Note 4, I keep 4 batteries ready to go at all times. When I think one is getting stressed, I throw it away, and use another.

42) Message boards : Cafe SETI : If you were going to live in the USA which state would you choose to live in? (Message 1773271)
Posted 22 Mar 2016 by Profile SciManStevProject Donor
There are so many factors, both geological and cultural. The US is very diverse in both of those areas. In the western states you could be subject to wild fires, or earthquakes, but the climate might be very nice. I hear northern California has a nice climate. The deep south is quite hot and humid, but Texas is a bit dryer. I live in the north East, so I have adapted to shoveling snow. Near the east coast, there is a possibility of hurricanes, but living near the ocean can be very nice. I enjoy mountains, which are prevalent in Kentucky, West Virginia, Tennessee, and others. There is also the possibility of tornadoes, especially in the more flat regions. Music is in all flavors in most places, although some states are more tuned to one kind or another. Another thing to look at is what type of industry are you looking for. Hi tech, farming, logging, customer service are just a few. There are so many parts of the US I have never seen, and would like to.

Weather/geological events affecting any given house are rare, but they do happen. Rivers can flood, but if you are outside the flood plain, then you will see rain, but not flooding.

For my part, New Hampshire has 40,000 miles of lakes, rivers, and streams. It touches the ocean, and has beautiful mountains. Much of it is forest. I got used to shoveling snow, but it is certainly not my favorite task....

This is another source of information. It is not free, but very well done.
I have seen the entire feature.

44) Message boards : Science (non-SETI) : Pluto is a Planet! (Message 1770797)
Posted 10 Mar 2016 by Profile SciManStevProject Donor
Pluto is one of thousands of Kyper Belt objects. It is the largest, but is in a band of material that more resembles rubble than planets. One thing that made it a dwarf planet is the following size comparison.

http://www.arcadiastreet.com/cgvistas/pluto_0050.htm

It is much smaller than our moon. They just saw more pictures that suggest it has clouds. The New horizons space craft is still sending back the data it collected, and may have shown us clouds. there is a possibility they may re-classify it as a planet again, but it is very small.

The 9'th planet, is so far nothing more than a mathematical probability based on measurements of other objects. It may be there, or it may not be.

Posted 7 Mar 2016 by Profile SciManStevProject Donor


I had wanted to post something about this a couple of days ago but forgot to... thanks for the reminder. :^)

It's probably update KB3140743 which has been implicated in causing many problems including BSODs, inability to boot even into Safe Mode, extreme slowdowns, etc.

Hope this helps, and would advise to disable automatic updates.

This is the update that has been giving me problems, and from what I read on Microsoft forums, I am not alone. In my case it won't install, but takes about 8 reboots, 4 of which fail, and 4 reset it to before the update, before it returns to normal, then tells me I need the update. :(
I expect it will be straightened out this week, but I really don't know.

Last night some Win 10 updates were available, so i installed them. Only one worked, and Windows said the other failed, and reversed it. It had to reboot several times before I finally could log on. In the process, it decided that my pdf viewer should be Edge, instead of Adobe Reader. I knew the latest Adobe Reader version had problems with another program I had, so I removed the latest, and installed the previous version, before the cloud system. I tried the failed update again, and the same thing happened. After numerous reboots, I logged on, and resumed crunching.

That was a real pain in the butt, and I wonder what will happen now that my system refuses to install these updates.

Posted 1 Mar 2016 by Profile SciManStevProject Donor
Nothing definitive. The screen saver is just eye candy. It may find signals, but they first must be confirmed by your wingmen. Then they are eventually picked over by the seti servers, and determined if they are something interesting or not. Then, they may point the radio telescope back at the source, and see if the signals repeat. A determination of whether a signal is good may not occur for a lengthy time after your machine has calculated it. Since the screen saver, is just for us to have something to look at, most of us just turn it off, and let the extra computing power go to solving the equations, instead of producing eye candy.

Since mass-less gravitons, at extreme energy levels also propagate at light speed, this does not leave much room for the possibility of FTL travel.

Photons are traditionally said to be massless. This is a figure of speech that physicists use to describe something about how a photon's particle-like properties are described by the language of special relativity.

It is almost certainly impossible to do any experiment that would establish the photon rest mass to be exactly zero. The best we can hope to do is place limits on it. A non-zero rest mass would introduce a small damping factor in the inverse square Coulomb law of electrostatic forces. That means the electrostatic force would be weaker over very large distances.
That is travel time for the astronauts. How many years pass on earth between departure and the return to earth?

At 85% light speed, there would be some relativistic effects, but not to bad. The real changes would be at over 95% light speed, increasing rapidly as light speed is approached.

Posted 4 Feb 2016 by Profile SciManStevProject Donor
85% of light speed is quite acceptable. That means the nearest star could be reached in 5.3 years, say a 12 year round trip. So are these 85% designs feasible?

The design I read about has a scoop almost the size of the moon, that looks like a radio dish. In space, these is about 1 atom of hydrogen per the volume of a grape fruit. The scoop would gather the hydrogen, then fuse it releasing energy. the vessel would be self refueling, but the size would be enormous. I keep wondering what would happen if a micrometeorite or larger object hit it somewhere.


5.3 years if it doesn't takes years to accelerate up to speed and years to decelerate. That could possibly double, triple or more the time from what I understand.


That is very true. I don't think the human form could withstand much more than 1 G for lengthy amounts of time. I think the idea of Star Wars ships just zipping around, even at normal speeds would tear a person to pieces.

A photon is a mass-less particle. If you add more energy to it, it just has more energy, but doesn't go any faster. Even light speed is tricky to obtain. Some of the best ship designs I have read about would only achieve about 85% light speed. most are around 15%. Interstellar travel does seem extremely difficult, but intergalactic travel seems inconceivable.

Posted 3 Feb 2016 by Profile SciManStevProject Donor
The clue is to fool physics into thinking you have zero mass, then the restriction won't apply. Solve that one and FTL is there.


I don't think so. Even with zero mass, there is no way to accelerate beyond light speed. If you need a force such that with every action, there is an equal and opposite reaction, and no force exists to create that reaction, then mass doesn't matter.

We all get them.
http://setiathome.berkeley.edu/sci_status.html
What happens next, is that the results are run through another process, which has not been working lately to shift out possible candidates.
http://setiathome.berkeley.edu/forum_forum.php?id=830
Once we have identified a possible target, we take another data sample, analyze that, and see if it repeats.

The verification process for any given signal is very stringent.
The scientists running the project want to make sure we have something valid before we alert the world.

Hi. Too bad Mac users still penalized for not being able to "show graphics" Thought it was to be a screen saver.

The screen saver just slows down data processing, and gives eye candy in return.

Lower stage boosters fall back to Earth, but a number of orbital stage boosters are still up there, all be it in decaying orbits.
Boosters are basically tubes, so could either be used as tubes, or sources of the sheet metal and composites they contain.
Further on the idea of scavenging space junk, what about solar panels from dead sattelites?

One issue I see about old solar panels, is that the new ones are much more efficient, and the output of all solar panels begins to decay after about 10 years. I am not sure if the materials can be recycled, but the panels themselves, most likely not worth the effort.

58) Message boards : Cafe SETI : Thinking of going SOLAR and/or WIND? (Message 1752250)
Posted 29 Dec 2015 by Profile SciManStevProject Donor
The company I am currently buying power from just locked me in for 18 months at 10.19 cents per KWh, which means that with the Solar City plan, I would lose money for several years. That with all my other concerns has officially made going solar at this time impracticable. I have rejected the offer.

Steve


10,19 cents? Is that solely the energy cost? Would be an awful lot if it were..

Yes, transmission over the lines is additional, but for here, that is the lowest rate there is. Recently, I stopped crunching for a couple of months. I had my computer, chiller, and support hardware running, but it wasn't crunching. The savings in just electricity was $170 a month.

The 13.9 cents per KWh was higher from solar, and it was set to increase every year, while my current rate is not. I do understand that a lot of my bill is paying for the transmission of the electricity over the power lines, and electricity generated locally would not incur that delivery charge.

In the future, I may re-visit this, as i would really like renewable, energy independence. What SolarCity was offering me, just wasn't where I wanted to go yet. One of the worst aspects was that I could not use solar to supplement my generator in case of a power outage. by law, all solar contributions had to be shut off during a power outage, leaving me with just my generator, exactly as I do now in case of power outages.

I use ESET, and have installed it on hundreds of computer repairs. It usually bounces around the top 5 antivirus programs, but things can change from day to day. What I do like is two fold. First, it uses very few resources, and scans every file coming into or leaving your computer. Second I have never had a compatibility issue with either software of hardware. It is a perfect solution for me, and many of my previous customers. The last infection I got myself was close to 20 years ago.
