I've also got very little spam on my Gmail address as well..
Intel i7-3930 @ 4.3Ghz,
4x1Tb spinning HDD in RAID 1+0,
Asus Nvidia 760GTX (I think..).
Asus P9x79 pro motherboard.
Using the integrated sound, but with a PCIe wireless card.
1600x1200 Dell lcd monitor (yep, still in 4:3 land).
Closed circuit watercooling on CPU.
I have to send the motherboard away for repair as a BIOS update failed - for the second time on this board - I've already had a warranty replacement for failed bios update.
Samsung S4 Active (personal phone).
Iphone 5s (work phone),
Galaxy S2 mini (spare phone),
GPS usb dongle for my desktop PC,
Garmin satnav device in the car,
Garmin Edge 500 bike computer,
old Garmin handheld eTrex mono GPS ~8 years old now.
Easy enough to rack up the device count when a techie for long enough and involved in active sports.
You can measure the resistance of an air filter by checking the pressure difference before and after the filter element. In all of the tests that I have seen the airflow resistance due to a stock filter is miniscule, and there is more pressure loss due to a bend in the pipe than due to the filter. Putting an ineffective filter that passes lots of grit through it, may be less pressure loss, but 80% of a miniscule number is still miniscule and has *no* measureable effect on power.
Otherwise I completely agree with you.
There's a lot to be said for a car company continuing to use a known-reverse-engineered protocol for the inter-module communications and code interrogation such as the protocol used by VAG on all of their cars. That makes things a lot easier, being able to use an inexpensive cable and software to access the same items as the main dealers.
Here in the EU, if there are terms in an employment contract that effectively mean a non-compete for X length of time after leaving that employment, they are completely unenforceable once the employment contract is terminated. The key terms are "contract" and "terminated". The contract no longer exists legally once the employment is terminated.
If a company wants non-compete methods, then they have to request that the newly-ex-employee sign a new contract to not compete with the previous employer's competitors, and in every case that I have heard of, the monetary terms for that non-compete had to be very very generous in order for the newly available employee to not work for the next 6 to 18 months in the business. Some in this situation went on training courses to stay current, others branched out into differing areas of work, all while getting handsomely paid not to work for the competitor.
Amazon have their head up their ass regarding the treatment of their employees for a long time in the US, and it'll come back to bite them. At least in the EU the employee protection legislation prevent such entities from taking that level of advantage of their employees. I'll be glad if/when karma comes back to burn Bezos and gang over their unethical actions and general mistreatment of their staff.
Another way that the US system is thoroughly broken, is the way that bills in most other countries are exactly for the purpose of the bill where in the US you have the riders and amendments that have absolutely nothing to so with the main bill.
When the free market extends into politics, it can only mean bad things for those that cannot afford to purchase their public representatives the same way that the corporates can..
One is a commuter bike piece of crap singlespeed (at least it's got 105 brakes that work) that I can leave locked up in the university overnight without much worry about theft. The next bike is my full-carbon Trek Madone 4.5 road bike, with nice upgraded Mavic Ksyrium wheels with the blade spokes. After that is a Giant Reign X1 "cross-country" mountain bike with 6.7" suspension in the rear, with some lightening done to the bike. Last but not least is my carbon Santa Cruz V10 full-on absolute top of the range 10" suspension downhill bike - which is actually lighter than my XC bike.
I try to ride at least once a week for a few hours on either the Trek or the Giant, reserving the V10 for uplift days at the local bike park or the annual trip to the Alps to take advantage of lift-serviced trails. The commuter bike is great for cycling in to meet my mates for lunch or for drinks in the evening as I won't drink and drive.
Biking is great. I get to see some lovely parts of the country, and the views at the top of the climbs are nearly worth it, but the descending really does make it all worthwhile!
Though I do need a secure shed instead of having the bikes in my kitchen..
You can have either a doubling of aperture and have the power the same, or you can have double the aperture and double the power and have the f/ratio the same.
If you have a doubling of aperture and maintaining the magnification the same, your diffraction disks (Airy disks) are half the width, and the image has 4 times the light coming through. In itself at low magnifications you may not be able to see any more detail as such, but because you now have that much more light to play with you can up the magnification and see more detail, and more contrasted details with the 12" than the 6". You'll note that I did not specify at the same magnification, only that the 12" will outperform the 6" in every way. Having 4 times the light is already performing better by one metric. Having twice the resolving capability is another metric, better utilised with more magnification.
Can you instead show a situation where a 6" scope of any type optically outperforms a well built well cooled 12"?
I recently upgraded from a 200mm Newtonian with a
As for the OP's point, you'll still be well able to see the three shadows, and Ganymede in silhouette against the cloudtops, and you'll be well able to see Io when it's in eclipse again silhouetted against the cloud tops. I've been able to see shadow transits very easily with my 70mm and 80mm ED refractors, so you should have no problem with your 110mm scope. It'll be small for sure, but still visible
I've been an observational astronomer for about 30 years at this stage, and I'm saving to get myself a nice 28" f2.7 Webster scope as my perfect scope, both for planetary and deep sky observations.
The one second per year difference is more than 3 magnitudes different to with the 35 minutes a year that solar time varies by.
The sidereal day was always much easier to time, with transit telescopes.
It was an eyeopener to see some apps that were misbehaving or just outright being illegal. My flashlight app now only controls the LED on the rear, and cannot see any of my private details - and they earned themselves a 1-star review..
