132,162 | Edit: Let me first thank all of you for being patient with me (I’m by no means a physicist) and for answering my question. This is an update to my previous question. I’ve done some research and to the best of my knowledge the idea that multiple universes could exist is a result of cosmic inflation and the principles of uncertainty in quantum mechanics. Basically (as I understand it) the idea is that during cosmic inflation after the Big Bang due to these uncertainties in quantum mechanics different regions of space time began their ‘Hot Big Bang’ period at different intervals. Thus the gap between universes is the result of the continued inflation of the universe after this happens. So my new question is: could we not just travel there via space? Grant it would be very difficult considering space is still inflating making the distance between universes farther and farther as time passes. But let’s say we use a little handwaving and make it so the teleportation of organic matter is possible or we create a wormhole that won’t collapse almost immediately upon formation and won’t kill us. I’m trying to fill the gaps with as much actual science as possible and whatever is still vastly unknown can be filled in with pseudoscience. Thanks again. | 2018/12/05 | [

2. The central mechanic control how information pass from one universe to another. It is somewhat similar to "type cast" in programming, where there are similar type in other universe that can "simulate activity" of this information
3. The material part of human in one universe do not travel, but they get sensor (eye, touch...) information from that other universe, and their command (movement of body) pass to that other universe. Give feeling similar to how you dream.
4. The tech required: information about how to communicate with central mechanic and with other universe. No need for material movement. | Travelling the multiverse is currently magic because our physic and mathematical models are not up to the task of adequately representing fifth or higher order dimensions required to plot an exit point and return safely.

] | As you implied, there is no hard science answer. I can tell you some ideas that I think about sometimes which may have similarities in essence. String theory mixed with modulation. If your character can figure out how to modulate the frequency of string vibrations and create new harmonics the result may cause a disruption in the fabric of the space-time continuum. This technique might be used in conjunction with a device to simultaneously match the characters own string vibrations with another universes string vibrations. | Travelling the multiverse is currently magic because our physic and mathematical models are not up to the task of adequately representing fifth or higher order dimensions required to plot an exit point and return safely.

] | It becomes very simple if we are right in our understanding that our universe could be a simulated universe rather than a real one.
Because all manner of simulations are possible it is even possible to have simulations of universes being emulated inside currently running simulations.
(such as when we run gravity simulations etc).
So the chances of being a simulation are much higher than the chances of being in the real thing.
So in this case travel to the multiverse might only involve transfer of data.
Any violations of the laws of physics could also be conveniently explained by the changes data values while the simulation is running.
For instance walking on water could be fixed by running the code
If height < 0 then set height = 0 and the object would appear to be floating or levitating. | Travelling the multiverse is currently magic because our physic and mathematical models are not up to the task of adequately representing fifth or higher order dimensions required to plot an exit point and return safely.

273,182 | A lot of apps keep my phone's screen on (for example, youtube). Does Pokemon Go do the same thing? I'm asking because when I play the game, my screen turns off after a few seconds. I have to keep touching the screen so it won't turn off. The problem is that when I touch the screen, I lose the orientation that I am facing when I'm in "compass mode." If it is supposed to stay on, is there a setting or something that keeps it on?
I saw this [question and answer](https://gaming.stackexchange.com/questions/272559/i-found-an-egg-what-do-i-do) which says that you are supposed to keep the game open to hatch an egg. Does that mean you have to keep touching the screen to keep it active?

The link is below.
[Wakey](https://play.google.com/store/apps/details?id=com.doublep.wakey&referrer=utm_source%3Dstackexchange%26utm_medium%3Dcomment%26utm_term%3Dpokemon%252Bgo) is an Android app that is built to keep your screen on, on your terms. I've worked very hard to make it work well and be simple to use, and gives you lots of options which may improve battery life while using Pokemon Go. It works better than the "Battery Saver" mode included in Pokemon Go, which only really works when the screen is upside down. Wakey works in any orientation.
You can choose a mode that will allow the best combination of screen and battery - you can choose CPU only (this allows the screen to shut off, but the phone stays awake. I'm not 100% sure this is compatible with Pokemon Go, but if not...), or you can choose "Minimal Brightness" mode, which lowers your screen to the lowest brightness, but keeps it on. Finally, there's "Allow Dimming" mode, which lets the screen go partially dim, but not fully dim or off. I would recommend trying the modes in that order, as they are listed in the order of most battery saving.
With Wakey, you can set it to keep your screen on manually, or as long as Pokemon Go is on screen (or any app or apps you choose), or as long as the device is charging (the Auto features require in-app upgrade to Premium, but everything else I'm talking about here is free).

] | **Yes.**
The biological feature you're looking for is called **segmentation.**
Arthropod exoskeletons have very defined functional units broken down into groups called **tagma**. These tagma are groups of segments such as the thorax, the head, the abdomen, etc. Each of these groups are connected by joints.
After all, the word *arthropoda* means "jointed legs."
It doesn't necessarily have to be an insectoid creature but insects are among the arthropods along with other creatures like crustaceans and arachnids. The material **chitin** (which is a polymer) connects the joints in these creatures, and it's noted for being very flexible and durable.
In regards to your flexibility in the torso region, I found in *New Zealand Journal of Zoology (1986)* a detailed maneuver of a female jumping spider called the *twist lunge*.

Flexibility as described above is something you want to look for when trying to make creatures like this, since it utilizes [anatomical terms of motion](https://en.wikipedia.org/wiki/Anatomical_terms_of_motion) (Flexion, abduction, elevation, rotation, etc.) | According to [this](http://blogs.cornell.edu/naturalistoutreach/files/2013/09/Exoskeletons-1dvznk6.pdf),

The question here is how flexible you want the exoskeleton would be. Also, it would be nice if you provided the fictional video game insect species you were thinking of as FrostFyre requested in the comments. I'll update my answer once you do. |
34,790 | [](https://i.stack.imgur.com/h4LSQ.png)First - my question: After the orbit insertion, in the coast stage, and assuming perigee is out of the atmosphere, and neglecting any external forces and influences - is the orbit now "fixed"? As in, should apogee, perigee, eccentricity and inclination now be fixed values?
A bit of a background:
I am working on a spaceflight simulator [FSX SpacePort](http://www.terrabuilder.com), and currently, I am implementing cockpit instrumentation. I have a display that shows the location of my spacecraft, as it ascends on a trajectory towards the orbit. The display is dynamic - it shows the orbit's changing shape as the spacecraft progresses towards its intended orbit.
I have implemented an algorithm and pseudo code I found [here](https://space.stackexchange.com/q/1904/195) (using C++), and in this basic form, all works and looks good.
When I reach apogee and try to circularize, and as eccentricity nears 0, I cut out my first stage engines. Because the engines have a bit of a ramp-down time, it is always a bit of a guess when to cut the engines off so that the eccentricity would be as close to 0. I do this manually, and I might put in some algorithm in the future to do this for me.
The problem I have is, after the engines are off and the launch stack is coasting, the parameters of my orbital ellipse keep changing - by a small amount at first, but then, progressively faster, the perigee descends back into atmosphere and I eventually crash into the ground.
I thought that, without any external forces, the orbit is "stable" - the orbital parameters (apoapsis, periapsis, eccentricity...) would be fixed and not changing. Before I check my physics code (which has so far been reliable), I thought I checked first if I fully understood the astrodynamics.
thanks!
*edit: I added the screen caps of the orbital display. The time stamps are at the bottom, the 3 images show the span of about 10 seconds. You can see how, a, b, e, apogee and perigee (values are in km, above ground) are changing... inclination is rock steady.
Symbols:
- diamond is the spacecraft position
- full dot is apogee
- hollow dot is perigee
- also, "apo" and "per" numerical readouts are flipped, it's a bug...*
*edit 2: OK - My physics guy looked at my code, and almost immediately saw what I was doing wrong - and it kind of surprised me: I was assuming that my gravitational constant was indeed a constant, at 9.81 m/s^2. At orbital altitudes, it is actually a variable that depends on altitude. I inserted 2 lines of code that properly calculated the g vs. altitude relationship, and sure enough, the values are rock steady, exactly where they should be! So - the problem was in me assuming a "constant" gravitational constant!* | 2019/03/13 | [

] | If the spacecraft is out of the atmosphere, and the modeling is two-body (e.g. Earth and spacecraft and no other massive bodies are present in the model), and solar wind and other effects are not modeled, then yes, apogee, perigee, eccentricity and inclination should remain fixed.
If that's not what you're observing, then either the simulation thinks some additional force is still acting, or there's a problem with the simulation engine.
The orbital parameters changing "by a small amount at first, but then, progressively faster" is suggestive of atmospheric orbital decay, so my first questions would be:
* What altitude is your orbit?
* How do you know that FSX SpacePort considers that to be "out of the atmosphere"?
* What happens if you insert into a much higher circular orbit, say, twice the altitude? | Ok, a little while ago I heard back from the author of the Physics Engine, and this seems to be a special case for the engine, that requires a bit of enhancement. It is at the edge of my understanding, but basically,
*"you are applying a non linear force to the body but a simple semi-implicit integrator is not enough to reproduce a large scale integration. There you need to implement a mini integration step to advance the model in time, then use that value as a correction force. The engine does that for angular acceleration, but not for gravitational acceleration, for gravity if G is constant, the Semi implicit integrator is accurate enough."*
From what I understand, the direction of my gravitation vector is constantly changing (Earth is not flat!) and the integrator has trouble keeping up.
I will mark answer #1 as the correct answer, since it answers what I asked. |

This need not, and should not be confrontational, but ask if he is still interested in mentoring you, and if he is resistant, what could be done about it. If he's just having a hard time, and has a lot of pressure, he might be acting this way because he is struggling himself. If this is the case, you can one or both approach your project manager and discuss a re-shuffle of his responsibilities with respect to mentoring you. Please be careful to make sure this conversation doesn't sound like you are accusing him of anything, particularly of being incapable, as he will probably take exception to this and become more difficult to work with.
On the other hand, you may very well have done something to warrant his reaction, if so, the initial conversation can also shed some light on this. In my experience, some folk have trouble admitting that they are annoyed with somebody else for a plethora of reasons - so break the ice yourself - ask if he is displeased with your response to his mentoring, and discuss any weaknesses you may have with him. Try to schedule some time to really crack any difficult topics you may have asked him about a few times, but might have been too embarrassed to admit to not grasping. Also try to come up with a more structured approach to any mentoring - maybe a brief 2 minute summary each day/week to air out any problems in smaller chunks.
If there is not a reasonable outcome, you may then want to discuss the issue with the project manager/senior person to control the situation with more structure.
Be open to the extremes of possibility: that you may have annoyed him, that you might not be the reason for his reactions, or that he just plain doesn't like working with you.
Good luck, and I hope you resolve this. |

This guy's story ran something like this: he had been working as a landscaper, then as a grunt in an animal shelter - neither of which paid particularly well. He volunteered to maintain the animal shelter's website. This gave him enough experience with HTML and CSS to get a 'real' job with a startup. He spent most of his time working on the HTML formatting for email messages, however at various points he was expected to work on 'back end' stuff, which was written in Visual Basic and SQL Server. He had no idea what he was doing.
In this circumstance, there's no reason he should have - he had never taken any computer courses beyond perhaps an Intro to Programming. The employer's expectations were grossly unrealistic.
What I showed him with SQL Server and Visual Basic was enough for him to know he needed to take some classes, which he did. He switched jobs, explaining his circumstances to his new employer, which had more realistic expectations.

In this situation you are going to have to 'go your own way'. As long as you remain in the job that you're in, you'll have to 'hack the system' - figuring out what you can. Generally, however, if you can't find something productive to do right away, they'll let you go.

] | English does use what's sometimes called the "suppositional future," which is what your example is called. There is nothing wrong with the sentence, but it tends to be used in a rather restricted context.
The simple suppositional future is equivalent to the present tense plus words like "must". We use it very rarely these days. "You boys will be wanting some supper!" Which means "You boys must want some supper."
The suppositional future perfect (which you have) is a bit more common. It equates to the present perfect tense, but with uncertainty. So "He will have reached the boat by now" means "he must have reached the boat by now" or "I'm sure he's reached the boat by now." In question form, it's much the same as adding "I wonder". "Will he have reached the boat by now?" means "I wonder if he's reached the boat by now?"
Using this form adds a good bit of urgency to the statement. It sounds like you're very anxious to know what's happening. It's something to use sparingly, if at all, but you do want to understand it if you see it in print.
French, Spanish, and Italian all use the suppositional future much, much more than English does.

13,591 | Gibson assembly uses T5 exonuclease to chew back the 5' end of dsDNA to generate overhangs. However, T5 exonuclease, in contrast to lambda exonuclease, is reported to have ssDNA endonuclease activity (<https://www.neb.com/products/m0363-t5-exonuclease#tabselect0>).

Jon Sayers, University of Sheffield. | I've never actually done a Gibson assembly, but looking over the protocols at the New England Biolabs website, I think the answer must be that the ssDNA exposed by the T5 exonuclease is quickly protected from the ssDNA-endonuclease activity because it (the exposed DNA) anneals with the complementary sequence on the other component of the assembly reaction. Following that, any gaps are repaired and sealed by DNA polymerase and DNA ligase. All of these enzymes are of, course, present at the same time in the one-step assembly reaction.
In summary, under the conditions of the assembly reaction, the low-level ssDNA endonuclease activity of the T5 exonuclease is simply outcompeted by the other reactions taking place. |

All the planets of our Solar system have similar pages of their own, also using [astronomical symbols](https://en.wikipedia.org/wiki/Astronomical_symbols), for example [Neptune's Symbol page](https://solarsystem.nasa.gov/multimedia/display.cfm?Category=Planets&IM_ID=265). The credited [Lunar and Planetary Institute](http://www.lpi.usra.edu/) is a NASA funded institute in Houston, Texas, devoted to studying the solar system and sharing the excitement of space exploration with the public.
Being somewhat time-constraint, I wasn't able to find any mission imagery (observation data, telemetry data readings, mission control software, or any other such media with possible notations) that would use these astronomical symbols for planets. But as the time goes by, I'm pretty sure someone will find something, and I don't see why NASA using astronomical symbols also for other uses besides acknowledging they exist and describing them would even be considered anything unusual. Press kits might be watered down for easier consumption of the general populace, but for their internal use and where as concise as possible notations would be required not to obstruct other meaningful data, I imagine they'd use them frequently. | Mariner Jupiter Saturn, later named Project Voyager, initially had the Jupiter and Saturn symbols on the project logo. |

2,167 | I am having trouble articulating a statement of intent because of a few things. But to keep on point for Stack Exchange I'll focus only on one: interdisciplinary coursework.
I have spoken to a Fine Arts Department at my top choice and they not only permit but promote taking interdisciplinary courses. My intention is to take as many courses as I can in Psychology while doing the MFA, as well as any required training to use the Eye-Tracking facilities.
1. Should I specify professors from both departments?
2. Should I mention that after I complete the first degree (MFA in my case) I plan to pursue a PhD in the other field (Visual Cognition in my case)
3. Should I state research goals in both fields or keep it to only the school I am initially applying to? (In my case: In the immediate I want to research neurotypical perception through visual design for clearly communicating complex ideas. Eventually though (as in during the PhD if not Post Doctorate) I want to research atypical perception and how to design visual communications that can be easily understood by people with disabilities. I am not sure which disability but mostly Autism Spectrum Disorders, however I also think there could be a strong use for this research in assisting those with Alzheimer's.)
How much of this cross disciplinary information should a person state in their Purpose Statement / Letter of Intent? My concern is that I don't want it to sound like I only want the Psychology Department and leave the committee wondering why I am going for the MFA in Design first. | 2012/06/26 | [

] | In general, the more concrete your essay is—and the more it shows that you've thought through your plans and potential options at the school to which you are applying—the more strongly it will be considered.
Moreover, if you're pursuing an unconventional path, such as applying for psychology but also going for an MFA in design, then you'll probably want to make that clear from the very outset. Otherwise you run the risk of the faculty—which normally makes admissions decisions at the graduate level—thinking you've hoodwinked them somehow. When that happens, that can make your life very uncomfortable.
So you should mention your full degree plans including, if possible, professors from both departments.
*However*, when it comes to writing the essay for admission, that depends a lot on the specific program you're applying to. If you are applying only for a master's program in psychology, then you should talk primarily about psychology-related topics. Your proposed work in design should amplify your psychology work, but not dominate it. On the other hand, if you're applying directly to the PhD program, and the MFA is an integral part of your plans, then you need to explain that at the outset, and should indicate what goals you'll achieve in the MFA that will help you with your PhD. | I disagree with [aeismail](https://academia.stackexchange.com/users/53/aeismail), but with some qualifications.
Generally, I encourage you to lay out your goals and overall plan, including both MFA and PhD. It's vital that you convey your *thought process and justification* for this plan, not just the plan. Is this an impulse? Or has it been many years in the making? Why does this plan suit *you* with your unique skills, capabilities, and disposition? Why does this plan fit the University and department that you are applying for? What about this plan is well known and what is uncertain and unknown?
For example, you should be able to answer this critical question: Why bother with the MFA first? Why not just enter an interdisciplinary PhD program now? What does the combination give you that neither, alone, would provide?
Have you evaluated the many Design Schools (D-Schools) at major universities? Stanford, MIT, and many others have these. If a PhD from these D-Schools won't meet your needs, explain why.
In all of this, what you are really communicating to the committee is what is *unique about you* for MFA and *how you will be successful* in the MFA program.
---
The qualification is that admissions criteria and process is very different for Masters vs. PhD. In Masters programs, no one cares whether you will be a valuable member of the academic research community. What they care about is: can you succeed in the course work (and thesis or capstone project, if required), and will you be a valuable contributor as member of the community of students. In PhD in Psychology, admissions is nearly always determined by whether you are the most attractive research assistant for one of the professors, given their interests and funding.
Therefore, when you write your Masters application, you need to emphasize how your preparation and previous academic work set you up for success in course work and engagement with other students. |

Let's have a look at the "Bluelight Filter for Eye Care" app's permissions in the "PlayStore":
1. Draw over other apps - **Could hide some malicious button hidden.**
2. Have full network access - **Could be harmfull by sending information from your phone.**
3. Run at startup - **Suspicious in some way (reminds me of some rat/keyloggers apps).**
4. Prevent phone from sleeping - **Ok.**
5. Install shortcuts - **Ok.**
6. Retrieve running apps -**Ok.**
7. Receive data from internet - **I guess that's for updates/Ads but could be harmful.**
8. View network connections - **Ok.**
9. Expand/collapse status bar - **Ok.**
10. View Wi-Fi connections -**Ok.**
Conclusion:
Anything in our world is/should be suspicious, even "Facebook" app (There are rumors that they send information to the NSA), but I still you use it.
all I'm trying to say is that you should be careful and check for the permission it requests and if you see something suspicious think again if you really need that and willing to risk your personal information for that. |

] | The problem is with the DRAW OVER APPS permission. Android will not let you change any system level changes or install anything while an app is overlaying your screen. The reasoning being since the app can hide a malicious request and have the button pressed under it. Be very wary of any app that requests this permission and make sure you truly trust the developer.
Check out this link for more details on tapjacking. [XDA Developers - Tapjacking](https://www.xda-developers.com/how-tapjacking-made-a-return-with-android-marshmallow-and-nobody-noticed/) | Yes, they absolutely create security risks. For them to work, you must grant them permission to draw over other screens on your phone, while passing touch events to the underlying screen.
A benevolent, well-behaved app draws a mostly transparent red overlay on top of all other screens.
A malicious app could very well display its own screens completely opaque while secretly passing your touches along to an underlying app. That means you might be doing just about anything, including granting the app more permissions or allowing it to install other apps without having any idea. |
524,749 | In a recent experiment, I have found the viscosity of glycerol by measuring the time it took for steel balls of measured density and radius to fall a certain distance in the liquid.
Now, I need to compare this data with a theoretical value given by a certain graph of glycerol viscosity by temperature. I have measured the temperature in the lab and know the average temperature throughout the experiment and its error.
In order to compare the values, I need to know how to properly take data from a given (printed) graph and calculate the error of the value.
I don't really know how to approach it, and it is not something that has been explained previously (nor did I find much data online about lab statistics).
A possible method I thought about is to add the resolution errors of the axes and add the error in measured temperature, but that would give an answer with inconsistent units. | 2020/01/13 | [

] | Light, even in quantum mechanical form, travels as a wave. Photons as individual particles only exist at the end of propagation, when that wave interacts.
That wave always propagates at $c$, the speed of light in a vacuum.
So how does refraction work? As the wave moves through a medium, it intersects with (usually) the electrons, causing them to vibrate. That vibration does not exactly follow the wave: the E field causes a force, which causes an acceleration, which builds to velocity. That motion of charge causes the *reradiation* of another, weaker, delayed wave. The combination of the original wave and the reradiated one results in the overall wave being a bit delayed. The more material traversed, the more it’s delayed. In that sense, it’s showing a slower velocity: the more material it goes through, the longer it takes to get there.
Note that this is a continuous coherent shaping of a wave. It’s not the scattering of point-like particles like balls in a pachinko machine. This is consistent with what we see: there’s no random scattering of light going through clear optical glass | Photons are massless and they do travel at speed c in vacuum when measured locally.
Though, in a medium, you can read phrases saying that the speed of light decreases. I do understand that you are confused.
If you want to go very basic, then you can say that the photons as they travel in the medium between the atoms and molecules, still travel in vacuum, at speed c. QM is a tricky beast because the photons do interact with the atoms/molecules in the medium. Now there are different approaches as to what kind of interaction this exactly is, that is, scattering (elastic or inelastic), or absorption and re-emission.
Without going into detail which one of those specific interactions is the real one (in reality we do not know), the interaction is there and needs time. The individual photons interact with the atoms/molecules in the medium, and this takes time. Though, the individual photons as they travel inbetween the atoms, they do travel in vacuum at speed c.
Nonetheless, the denser the medium is, the more interactions the photons have to have to propagate, and the more the speed of light slows down.

[How does light speed up after coming out of a glass slab?](https://physics.stackexchange.com/questions/153904/how-does-light-speed-up-after-coming-out-of-a-glass-slab) | The other answers explain how light appears to slow *when* it is slowed. But sometimes it isn't, and it was helpful for me to think of the limiting cases for light in water.
Imagine light entering water from a vacuum. Water has a molecular spacing on the order of a nanometer, so from the point of view of a photon with wavelength 1000 nm, the water is a sea of electrons. The photon interacts with the medium as a wave in a dielectric, and the other answers describe how wave-particle duality affects our understanding of the photon's travel.
Now imagine a photon with wavelength 0.01 nm -- an X-ray photon. To this photon, the water is mostly vacuum with some giant H2O particles wiggling around. Since the molecular spacing is much larger than the photon's wavelength, it will interact with the water more as a particle, traveling through the underlying vacuum until it scatters with a single H2O molecule. And we see this in the refractive index of water, which [approaches 1 in the nanometer scale](http://www.philiplaven.com/p20.html) (blue line in plot below).

99,387 | I want to do a photo shoot using film, but due to not being able to see the shots I've taken I would first like to take a digital photo, then recreate it using film.
If I used the same focal length, ISO, aperture size and shutter speed, would the photo was taken digitally be exposed the same as the film photo? Maybe crop vs non crop sensor may affect things?
If not, what can I do to achieve similar levels of exposure (I don't just want to rely on the film cameras light meter all the time)? | 2018/06/15 | [
"https://photo.stackexchange.com/questions/99387",
"https://photo.stackexchange.com",
"https://photo.stackexchange.com/users/75980/"
] | Even in theory there are differences in the way digital sensors and films record light that makes ISO values only approximate. But these differences are usually fairly subtle and theoretically exposure should be more or less equal if you use the same ISO, aperture, and shutter time. For more about this, please see: [Why are these film photos brighter than digital photos taken at the same time with the same settings?](https://photo.stackexchange.com/q/79524/15871)
In practice there are even greater differences that may affect each of these basic components of exposure.
**ISO:** Since digital sensors have a linear response to varying brightness levels of light and film has a more logarithmic response, comparing an ISO value for a particular digital sensor and an ISO value of a particular film is only approximate. This value is usually [closest in the mid-tones but will vary more in the highlights and shadows.](https://photo.stackexchange.com/a/79528/15871)
Keep in mind that not all films with a specific ISO/ASA rating have the exact same response curves. Some may have deeper blacks and brighter highlights for higher contrast while others may have lighter shadows and more restrained highlights for less overall contrast. These curves can also be manipulated by modifying exposure times and then compensating by altering the developing time. That's basically what Ansel Adams' 'Zone System' was about.
Compound that with digital cameras that actually use [different ISO values internally](https://photo.stackexchange.com/a/49866/15871) than they are labeled in the settings. They usually do this specifically to preserve highlight detail in the raw image data collected.
So digital cameras tend to have their actual ISO sensitivity for a particular setting rounded up. On the other hand, film manufacturers tend to round the sensitivity of their films down to the next nearest "standard" value.
With exposures for film longer than about 1 second the [Schwarzschild effect](https://en.wikipedia.org/wiki/Reciprocity_(photography)), sometimes referred to as reciprocity failure, must be taken into account. The sensitivity of films at longer exposure times is not linear. This must usually be taken into account when exposing film for longer than one second. This can very significantly impact exposure times, and it varies by the specific film in question. The manufacturer of your film should be able to provide information regarding how much compensation is needed for longer exposures.
**Aperture (Av):** Different lenses labeled with the same aperture value may not be equally bright. This is partly due to differences in transmission loss through the various elements of each lens. But at maximum aperture it is also due to the values of each lens being rounded to the nearest or (usually) next wider standard f-number.
The differences due to transmission loss are carried across the entire range of aperture settings. The differences between stated and actual aperture when wide open tend to be reflected in successive apertures settings as well in order to preserve the differences in stops between the maximum aperture setting and the others. Sometimes the further one moves from the maximum aperture the more "honest" the actual f-number is with regard to the actual diameter of the entrance pupil relative to the lens' focal length. By the way, focal lengths are also approximated and rounded to the nearest "standard" number in the most favorable direction!
Here are the actual transmission measurements for three different Canon "L" lenses with an "f/4" maximum aperture. Even when using each of the respective lenses on the same camera, the exposure values would need to be adjusted slightly to give the same brightness of exposure.
[](https://i.stack.imgur.com/TxNQO.png)
The EF 24-70mm f/4 is essentially an "honest" f/4 lens throughout its zoom range. The EF 17-40mm f/4 is one-third stop slower at about f/4.4 and the EF 24-105mm f/4 is two-thirds stops slower at around f/5.1.
**Shutter Time (Tv):** Like the other two basic components of exposure, shutter times are only approximate. Even the numbers we assign to them are [rounded to easy to use values](https://photo.stackexchange.com/q/49860/15871).
Of ISO, Av, and Tv, the latter is usually most consistent across digital and film platforms *if* the camera has an electrically controlled physical shutter or a purely electronic shutter. If the film camera has a mechanically controlled focal plane shutter or iris shutter, all bets are off as to which exposure components (ISO, Av, Tv) will be most and least accurate. | In abstract theoretical terms, the exposure parameters — aperture, shutter speed, and ISO — are the same no matter the camera or lens. In an ideal sense, f/2.8 at ISO 100 and ¹⁄₁₀₀th of a second will give the same exposure in the result on any camera.
You specifically ask if the sensor size makes a difference. It doesn't, as covered at [Do the same camera settings lead to the same exposure across different sensor sizes?](https://photo.stackexchange.com/questions/7800/do-the-same-camera-settings-lead-to-the-same-exposure-across-different-sensor-si/7801#7801). Exposure is per unit area, not across the whole frame.
In *practical* terms, cameras just aren't that precise, and any of the values can vary by a significant fraction of a stop. Digital ISO, in particular, is prone to a lot of variation from brand to brand and camera model to camera model. And, as Michael notes, there are differences in film and digital, especially regarding long exposures.
For your use of preview for film photography, though, **this can work**. I'd recommend shooting a roll with your preferred film in different situations, carefully recording both the digital camera's values and the settings you used on the film camera. Once you've done that, go through and compare the results; from that, you should get a general sense of whether you need to estimate up or down from the digital camera's metering — and whether there are situations which are special cases.
(See [Am I wrong to judge my exposure using my smartphone?](https://photo.stackexchange.com/questions/97073/am-i-wrong-to-judge-my-exposure-using-my-smart) for more.) |

] | Even in theory there are differences in the way digital sensors and films record light that makes ISO values only approximate. But these differences are usually fairly subtle and theoretically exposure should be more or less equal if you use the same ISO, aperture, and shutter time. For more about this, please see: [Why are these film photos brighter than digital photos taken at the same time with the same settings?](https://photo.stackexchange.com/q/79524/15871)
In practice there are even greater differences that may affect each of these basic components of exposure.
**ISO:** Since digital sensors have a linear response to varying brightness levels of light and film has a more logarithmic response, comparing an ISO value for a particular digital sensor and an ISO value of a particular film is only approximate. This value is usually [closest in the mid-tones but will vary more in the highlights and shadows.](https://photo.stackexchange.com/a/79528/15871)
Keep in mind that not all films with a specific ISO/ASA rating have the exact same response curves. Some may have deeper blacks and brighter highlights for higher contrast while others may have lighter shadows and more restrained highlights for less overall contrast. These curves can also be manipulated by modifying exposure times and then compensating by altering the developing time. That's basically what Ansel Adams' 'Zone System' was about.
Compound that with digital cameras that actually use [different ISO values internally](https://photo.stackexchange.com/a/49866/15871) than they are labeled in the settings. They usually do this specifically to preserve highlight detail in the raw image data collected.
So digital cameras tend to have their actual ISO sensitivity for a particular setting rounded up. On the other hand, film manufacturers tend to round the sensitivity of their films down to the next nearest "standard" value.
With exposures for film longer than about 1 second the [Schwarzschild effect](https://en.wikipedia.org/wiki/Reciprocity_(photography)), sometimes referred to as reciprocity failure, must be taken into account. The sensitivity of films at longer exposure times is not linear. This must usually be taken into account when exposing film for longer than one second. This can very significantly impact exposure times, and it varies by the specific film in question. The manufacturer of your film should be able to provide information regarding how much compensation is needed for longer exposures.
**Aperture (Av):** Different lenses labeled with the same aperture value may not be equally bright. This is partly due to differences in transmission loss through the various elements of each lens. But at maximum aperture it is also due to the values of each lens being rounded to the nearest or (usually) next wider standard f-number.
The differences due to transmission loss are carried across the entire range of aperture settings. The differences between stated and actual aperture when wide open tend to be reflected in successive apertures settings as well in order to preserve the differences in stops between the maximum aperture setting and the others. Sometimes the further one moves from the maximum aperture the more "honest" the actual f-number is with regard to the actual diameter of the entrance pupil relative to the lens' focal length. By the way, focal lengths are also approximated and rounded to the nearest "standard" number in the most favorable direction!
Here are the actual transmission measurements for three different Canon "L" lenses with an "f/4" maximum aperture. Even when using each of the respective lenses on the same camera, the exposure values would need to be adjusted slightly to give the same brightness of exposure.
[](https://i.stack.imgur.com/TxNQO.png)
The EF 24-70mm f/4 is essentially an "honest" f/4 lens throughout its zoom range. The EF 17-40mm f/4 is one-third stop slower at about f/4.4 and the EF 24-105mm f/4 is two-thirds stops slower at around f/5.1.
**Shutter Time (Tv):** Like the other two basic components of exposure, shutter times are only approximate. Even the numbers we assign to them are [rounded to easy to use values](https://photo.stackexchange.com/q/49860/15871).
Of ISO, Av, and Tv, the latter is usually most consistent across digital and film platforms *if* the camera has an electrically controlled physical shutter or a purely electronic shutter. If the film camera has a mechanically controlled focal plane shutter or iris shutter, all bets are off as to which exposure components (ISO, Av, Tv) will be most and least accurate. | A “good” exposure is defined as that that amount of light energy that produces an image with satisfactory tonalities and color characteristics. To allow repeated and duplicated results, the industry has standardized the ingredients of the exposure. 1. Scene brightness (Lux or Lumen level) as measured by photographic light meter system. 2. Sensitivity to light of film or digital sensor (ISO). 3. Shutter speed (accurate timing apparatus). 4. Capability of the lens to gather and transfer light (f-number).
Given the standardization there remain numerous pitfalls. The accuracy of brightness measurements are a variable based on the truthfulness of the instrument and the procedure performed by the user. The sensitivity of film is well regulated by the International Standards Organization, digital sensors only loosely follow these guidelines. Modern shutters are quite accurate, nevertheless there will be errors. The f-numbers are a ratio that equalizes all lenses, regardless of their dimensions. However this system is slightly flawed because the f-number does not take into account light absorption with the system.
Nevertheless, you can count on a reasonable like rendering of the subject provided the cameras are set to the same equivalent exposure. The differences encountered are facts of life. No two pictures taken with different cameras will be exactly alike. The difference is likely minuscule however when we compare film and digital there will are dissimilarities inherent to between the various medias. |

Film has exposure latitude that digital (still) does not. So even if exposure is not spot on, it can be adjusted in post.

This is basically how disposable cameras operate as well.
There are scenes that film cameras are more likely to have difficulty metering than digital cameras. If the camera misjudges by only a few stops, film latitude should be sufficient. Otherwise, you can use exposure compensation or exposure bracketing.
*Note:* When I write, "same exposure setting", I do not mean that ISO, shutter speed, and aperture have to stay the same. Rather, the settings can be adjusted with respect to each other to keep exposure "constant" without referring back to the meter.
The idea is to think of balancing a math equation in terms of "stops". If one setting goes up a stop, another setting has to go down. For shutter speed and ISO, multiply and divide by 2.

] | In abstract theoretical terms, the exposure parameters — aperture, shutter speed, and ISO — are the same no matter the camera or lens. In an ideal sense, f/2.8 at ISO 100 and ¹⁄₁₀₀th of a second will give the same exposure in the result on any camera.
You specifically ask if the sensor size makes a difference. It doesn't, as covered at [Do the same camera settings lead to the same exposure across different sensor sizes?](https://photo.stackexchange.com/questions/7800/do-the-same-camera-settings-lead-to-the-same-exposure-across-different-sensor-si/7801#7801). Exposure is per unit area, not across the whole frame.
In *practical* terms, cameras just aren't that precise, and any of the values can vary by a significant fraction of a stop. Digital ISO, in particular, is prone to a lot of variation from brand to brand and camera model to camera model. And, as Michael notes, there are differences in film and digital, especially regarding long exposures.
For your use of preview for film photography, though, **this can work**. I'd recommend shooting a roll with your preferred film in different situations, carefully recording both the digital camera's values and the settings you used on the film camera. Once you've done that, go through and compare the results; from that, you should get a general sense of whether you need to estimate up or down from the digital camera's metering — and whether there are situations which are special cases.
(See [Am I wrong to judge my exposure using my smartphone?](https://photo.stackexchange.com/questions/97073/am-i-wrong-to-judge-my-exposure-using-my-smart) for more.) | A “good” exposure is defined as that that amount of light energy that produces an image with satisfactory tonalities and color characteristics.

] | Of the options you listed cat seems to be the obvious answer, they are reasonably independent and quite a lot of them will enjoy a good cuddle.
I don't want to be rude or insensitive as I don't know your full situation but if you went for a long haired breed such as a ragdoll, or birman then they are like a nice warm fluffy teddy bear and you might enjoy the texture of the coat?
In terms of work load do you think you can handle the following:
* Feeding - cats will need feeding a couple of times a day, you can have then on a purely dry diet so that would mean filling a bowl with kibble a couple of times a day or a more infrequent filling of an automated feeder
* Water - cats need fresh water (especially if you are feeding them on dry food) so you'll need to fill a water bowl once or twice daily. Alternatively a pet fountain would allow for less frequent fills/changes
* Toys - cats love to play and need some entertainment, they like to play with their owners but it's not essential, there are many simple toys, soft mice etc and even interactive ones that will keep then happy. They do have a tendency to leave them everywhere though which may present a trip hazard?
* Toilet - if you want the cat to be an indoor kitty then that means a litter tray, normally you'd scoop the poop once a day and do a full change once every four or five days but given the potential messiness in trying to scoop blind it may be easier to just do a wholesale change every other day and leave it at that. An indoor/outdoor cat won't have that problem but you'll be needing a cat flap really for that.
* Travel - some cats can travel but I wouldn't rely upon it. They are very centred on "their" territory. If you are travelling between a couple of familiar locations then that's better for them. If you choose to leave then then they can cope for a couple or three days on their own with automated feeders but anything longer and you'd need to put them in a cattery
* Medical care - assuming no problems then a cat will need annual vaccinations at the vet, quarterly worming tablets and ideally monthly flea treatments and claw clips. The latter three can be done at home but I imagine would require assistance from a sighted person. Especially the claw clipping.
* Safety - most cats are pretty good at getting out the way, most of the time. However some cats are seemingly experts at being trip hazards. I've got one of "each" and little Mr Trip Hazard can materialize right under my feet at the most inconvenient times! | If you do get a cat, some of your requirements point to different age recommendations, so you should figure out what in your list is a higher priority.
If low maintenance/cuddling is your top priority, I would highly recommend an older cat (at least 5 years) over a kitten or young adult. An older cat is going to be lower energy and require less attention (play and cat proofing) and are usually more likely to just want to hang out on the couch with you. An older cat is generally not going to be comfortable traveling.
If being able to travel is your top priority, then you should get a kitten. If you accustom a kitten to frequent travel (and harness/leash training), then they'll be much more comfortable with it later in life.
That being said, I dated a guy who was legally blind and his favorite pet was guinea pigs (he had in the past had cats, rabbits, and guinea pigs). I'm not sure that his vision had any effect on that choice, but he didn't have any problem caring for his pets. |

They refer to different things altogether.
**Recovery** :
Recovery refers to the dedicated, bootable partition that has the recovery console installed. A combination of key presses (usually power + volume up) or instructions from a command line, will boot your phone to recovery, where you can find tools to help repair (recover) your installation, install official OS updates and/or custom ROMs and other stuff.
Recovery firmwares contain a custom recovery file that enables you to do a lot more additional things than what the stock recovery offers. This can include options to re-root your device, a file browser to browse through your files, format individual partitions and more.
**Kernel** :
Kernel is the core of the operating system that handles requests to and from the hardware, memory and process management and all the low-level stuff that is necessary for Android to be able to run. It is based on the Linux kernel with a few modifications to suit it to Android versions.
Kernel firmwares contain a kernel that, when installed, replaces the existing kernel and modifies the low level stuff in order to tweak the software to make better use of the hardware. Better battery life, higher performance, increased signal reception, etc. are some things a custom kernel can do.
**ROM** :
A custom ROM replaces your device's Android operating system — normally stored in read-only memory — with a new or modified version of the Android operating system. A popular custom ROM is CyanogenMod, which gives you a host of new options as compared to the original firmware.
ROMs may contain a different Android system altogether or might also include a kernel and/or a recovery. It's best to read the OP on those threads to find out what it contains.

This is subjective to the ROM you are referring to. Some ROMs use the RRO-Layers engine for theming, while others use the CyanogenMod theme engine. Some ROMs might have additional features over those present in CyanogenMod, others might have a different user interface altogether.
As to the unavailability of an S7 Edge version of CyanogenMod, this is because official builds aren't made yet or are in the works.

Again, these are subjective to the ROM you choose. Basically, some offer better performance, others offer better battery life, and a few more offer a mix of the two. It depends on which ROM you choose.
There are a few ROMs that might be more vulnerable to exploits than others. Therefore, it is recommended to go for an official build of a popular custom ROM, as they are tested and checked so that they would not contain malware.

] | Samsung Galaxy S7 has a stock browser app named - "Internet".
It includes ad blocking functionality as well as removing their containers on webpages. For it you will have to install one of the following apps from Play Store
1. [Adblock fast](https://play.google.com/store/apps/details?id=com.rocketshipapps.adblockfast)
2. [Crystal](https://play.google.com/store/apps/details?id=co.crystalapp.crystal)

Internet->More->Settings->Advanced->Block Content (enable the switch and choose the adblocker that you installed out of the above).
Unfortunately this is only an app based solution not system wide (which would only be available by rooting).
As far as rooting is concerned-
* don't try to do it.You will lose Samsung Pay, Private Mode, Warranty and obviously Knox will be tripped. (if you don't mind losing these features go ahead!)
**Ans 2**- On S7 you will not be able to use Cyanogenmod for many months or never (as Samsung has blocked bootloaders on Qualcomm versions and they don't give Exynos source code). Hence all ROMs on XDA are stock modified ROMs (only containing small changes like adblocker, some x kernel, some changes here n there but mostly stock)
If CM comes to S7 then you will have to install via 'recovery'.
**Ans 3** As these ROMs will be mostly equivalent to stock, they will operate normally (except until **You** modify it heavily). These ROMs won't come with Trojans for sure
**No, system wide adblocking can't be performed without root.**
**Least risky way to root will be flashing Chainfire's autoroot via odin (only Exynos)** | In principle you can root the device yourself and use iptables-based transparent proxying to forward DNS and http queries to proxies that are not running with root privileges. Then you don't have to trust anyone else's software to be installed as root. In practice I don't know if there's any good software setup to run this way on Android.
For what it's worth, DNS blackholing is one of the most effective ways to adblock in apps, and it's easy to do yourself. |

An official update could just as easily contain a backdoor, virus, etc and you would install it without a second thought. As long as it's done properly, phones being bricked as a result is not common at all, and is easily fixable if it does occur.
Rooting is extremely low-risk, but is currently not available for the S7 as they are still working on it. Things like that are also tested within the developer community before being released to the public.
As far as rooting, you MUST have the exynos version of the S7 for it to work. The Snapdragon version does not currently have a working root unless you install a custom rom.

] | The reason of why we have seasons, and those are always opposed in the North and South hemispheres, is because the axial tilt in the Earth rotation axis, which is 23.4°. This gives a huge difference of the Sun's light incidence over the planet between the Summer and Winter seasons.
Let's calculate the higher and lower effective Sun's light incidence over various regions of the Earth using a simple formula: **c = cos(incidence angle)**
In the regions near the 0° latitude (the Equator) the difference is from 100% Sun's light incidence at the equinoxes and 92% at the solstices (both twice a year) which gives the tropical regions barely the same temperature every day.
At higher latitudes (let's say Rome, at 41° 54′ N) the differences can be from 95% at Summer solstice to 42% at Winter solstice, which makes a hot Summer and a cold Winter.
If you want a region to have the same temperatures every day a year, your world should have its rotation axis perfectly perpendicular to its orbit (0° axial tilt). This way the temperature in a certain region will depend only on its latitude since you will no longer have seasons. | This may not be the answer you are looking for, but thought I'd post it anyway: if a country is close to the equator (e.g. Sri Lanka), the temperature would be same (approx. 30 degrees C) all year around. The day time is also fairly constant i.e. sun rises at about 6am and sets at about 6pm (variation through the year may be about 1 hour). |

] | A large body of water can have an enormously stabilizing effect on the weather. It is a common joke that weather at San Diego is the same year round.
While not entirely true, it does have some truth to it. Summer in San Diego usually has a range from 65F to 75F, while the Winter range is 50F to 65F. I live at about the same latitude, but several hundred miles inland (and several thousand feet higher) away from any body of water and temperature can range from 63F to 92F in summer and 27F to 53F in winter.
Water does not guarantee a mild climate though, as the Great Lakes region is known for its Lake Effect snow which can drop a substantial amount of precipitation in a short time. | The simplest answer was given above: give the planet a perfectly circular orbit with zero obliquity (no axial tilt) and each part of the planet's surface will receive the same energy from the star year-round. You could take this a step farther and assume your planet is orbiting a red dwarf star such that its habitable zone is close enough that the planet becomes tidally locked to the star, so the planet always shows the same face to the star. This can make the planet look like an eyeball (see here: <https://planetplanet.net/2014/10/07/real-life-sci-fi-world-2-the-hot-eyeball-planet/> or here: <http://nautil.us/blog/forget-earth_likewell-first-find-aliens-on-eyeball-planets>). For an eyeball planet the temperature structure would vary a lot across the planet but not in time.
The thicker the atmosphere, the more uniform the temperature across the planet's surface (Venus is the extreme example, but one to be avoided if you want life on your planet). I don't have a good feeling for the effect of the spin rate on the stability of the local temperature. Faster-spinning planets will have more "banding" structure in their atmospheres but I don't know if that is a stabilizing force. Someone with a specialty in atmospheric dynamics would probably know. |

] | Seasons are pretty universal, being caused by the angle at which the sun's light hits the planet. To make a point on a planet without seasons, you have two main options:
1. Give the planet's axis no tilt. This will allow you to have different regions with different temperatures depending on their distance to the equator, but no seasons anywhere else on the planet either.
2. Put the planet further away from the sun, so it is cooler overall. The tropics will still be season-less just like on Earth, but their temperature will be cooler.
A planet with an extremely thick atmosphere that blocks out the sun and heats the planet through greenhouse gases will have less temperature variation over the entire planet. Of course, such a planet will not actually be Earth-like. | A large body of water is **part** of the answer.
The water circulation in the Pacific Basin is clockwise (bringing cold water from Alaska to California) in the summer, and *counter*-clockwise (bringing warm water from the tropics to California) in the winter. The average water temperature off San Francisco (and probably also San Diego) is *higher* in the winter than in the summer.
This has a lot to do with the nearly constant temperature in San Diego. |

] | A large body of water can have an enormously stabilizing effect on the weather. It is a common joke that weather at San Diego is the same year round.
While not entirely true, it does have some truth to it. Summer in San Diego usually has a range from 65F to 75F, while the Winter range is 50F to 65F. I live at about the same latitude, but several hundred miles inland (and several thousand feet higher) away from any body of water and temperature can range from 63F to 92F in summer and 27F to 53F in winter.
Water does not guarantee a mild climate though, as the Great Lakes region is known for its Lake Effect snow which can drop a substantial amount of precipitation in a short time. | High altitude tropics
=====================
While San Diego has remarkably stable temperatures year round, there are other places that are even more stable. In tropical highlands, places get the same stable insolation as the steamy lowland tropics, but the air temperatures are mitigaged by altitude. This results in basically the most pleasant places on earth.
There are several tropical highlands straddling the equator. Africa has the Rift Valley mountains, from [Ethiopia](https://en.wikipedia.org/wiki/Addis_Ababa#Climate) and [Nairobi](https://en.wikipedia.org/wiki/Nairobi#Climate) in the Kenyan Highlands through [Rwanda](https://en.wikipedia.org/wiki/Kigali#Climate) and Burundi. All the cities in the Andes from [Caracas](https://en.wikipedia.org/wiki/Caracas#Climate) to [La Paz](https://en.wikipedia.org/wiki/La_Paz#Climate) have pretty stable temperatures. And through extraordinarily wet, the [highlands](https://en.wikipedia.org/wiki/Mount_Hagen#Climate) of New Guinea have very stable temperatures too. |

A planet with an extremely thick atmosphere that blocks out the sun and heats the planet through greenhouse gases will have less temperature variation over the entire planet. Of course, such a planet will not actually be Earth-like. | The simplest answer was given above: give the planet a perfectly circular orbit with zero obliquity (no axial tilt) and each part of the planet's surface will receive the same energy from the star year-round. You could take this a step farther and assume your planet is orbiting a red dwarf star such that its habitable zone is close enough that the planet becomes tidally locked to the star, so the planet always shows the same face to the star. This can make the planet look like an eyeball (see here: <https://planetplanet.net/2014/10/07/real-life-sci-fi-world-2-the-hot-eyeball-planet/> or here: <http://nautil.us/blog/forget-earth_likewell-first-find-aliens-on-eyeball-planets>). For an eyeball planet the temperature structure would vary a lot across the planet but not in time.
The thicker the atmosphere, the more uniform the temperature across the planet's surface (Venus is the extreme example, but one to be avoided if you want life on your planet). I don't have a good feeling for the effect of the spin rate on the stability of the local temperature. Faster-spinning planets will have more "banding" structure in their atmospheres but I don't know if that is a stabilizing force. Someone with a specialty in atmospheric dynamics would probably know. |

The day time is also fairly constant i.e. sun rises at about 6am and sets at about 6pm (variation through the year may be about 1 hour). |

Therefore, I'm asking which parts of Southern Thailand are safe from violence (arson, bombings and shootings)?
Also in above warning, it's advised to use hotels outside of Hat Yai’s central business district where actually I'm planning to stay over the night in Hat Yai city central. Is it really the case? I thought staying in central city supposed to be safer than in rural areas.

] | **TL;DR: All routes you're likely to use are tolerably safe.**
Broadly speaking, the insurgency affects only the eastern bits of southern Thailand: Yala, Pattani and Narathiwat. However, all 'standard' backpacker routes from Langkawi to Thailand, including the main train line via Padang Besar, go through the western side, *not* through any of those provinces.
Hat Yai is targeted because it's the largest city in the South, but then again, [Bangkok has also been targeted](https://en.wikipedia.org/wiki/2006_Bangkok_bombings), although the jury is still out on whether southern insurgents were responsible. Most bombings in Hat Yai have targeted places where Malaysian tourists come to cavort with Thai prostitutes (karaoke bars, rent-by-the-hour hotels, etc), so if you avoid this profile, odds are high you'll be OK. The vast majority of the "daily" attacks mentioned target Thai military and police security forces, not random passersby, much less foreign tourists. | Very few tourists have been killed or injured during the many years of southern insurgency. The violent acts target security forces (police, soldiers, village volunteers), government officials and school teachers. The tourists that have been injured or killed were all visiting the eastern side of the isthmus. As jpatokal mentioned your route travels up the west side of the [Kra Isthmus](https://en.wikipedia.org/wiki/Kra_Isthmus).
Ultimately you are putting yourself at greater risk by taking a bus, as more civilians (and tourists) are killed in bus crashes each year, than by insurgents. And if you are thinking about renting a scooter, three times as many people are killed in scooter crashes per year than the total number killed by insurgents since 2004.
The risk from insurgents is not something to worry about, other than the usual common sense precautions when traveling. |

Who says that clients don't need a UPS? All systems in our environment are protected by a UPS - from every server to each desktop.
You are correct that a UPS only delays the power outage. However when a power loss occurs the UPS communicates to the OS through a USB cable (most common nowadays). This allows the UPS to notify the OS when the battery is about be empty and the OS can begin **gracefull** system shutdown. This is something that is not possible in a normal power outage without a UPS. ***The power company will not call you and tell you that a tree is going to fall in 10 minutes and kill your power.***
Your assumptions about how a computer handles a loss of power are not realistic. Most of the time there might not be any harm, but there is no need to gamble. One problem on a production server and you will rue the day that you decieded you did not need a UPS. |

68,145 | What could be the main reasons for a short-haul flight to be delayed over an hour in-flight?
Recent [Lufthansa LH 2227 CDG-MUC flight](https://www.flightstats.com/v2/flight-tracker/LH/2227) took off only half an hour after scheduled time, but landed at destination delayed nearly an hour and a half.
[](https://i.stack.imgur.com/CgeTZ.png)
Meaning (if I am reading these stats correctly) that this particular flight spend an hour extra in the air over scheduled time. I begin to question if there is enough fuel for the plane to stay that long extra?
I flew the very same flight few days ago and that flight also took of half an hours after schedule and landed fifteen minutes after schedule. Meaning that a plane manage to "work out" half of its delay en route. This particular, pictured flight not only didn't work out its initial delay, but also added another hour to it while being in air.
I was always told (and saw that in my small commercial flying experience) that
* short- or middle-haul flights delayed 15-30 minutes on take-off,
* long-haul flight delayed 60-90 minutes on take-off,
are nearly always able to land on-time, effectively "working out" their initial delay during flight, by flying faster etc. What happened or could happen here? | 2019/08/27 | [

68,145 | What could be the main reasons for a short-haul flight to be delayed over an hour in-flight?
Recent [Lufthansa LH 2227 CDG-MUC flight](https://www.flightstats.com/v2/flight-tracker/LH/2227) took off only half an hour after scheduled time, but landed at destination delayed nearly an hour and a half.
[](https://i.stack.imgur.com/CgeTZ.png)
Meaning (if I am reading these stats correctly) that this particular flight spend an hour extra in the air over scheduled time. I begin to question if there is enough fuel for the plane to stay that long extra?
I flew the very same flight few days ago and that flight also took of half an hours after schedule and landed fifteen minutes after schedule. Meaning that a plane manage to "work out" half of its delay en route. This particular, pictured flight not only didn't work out its initial delay, but also added another hour to it while being in air.
I was always told (and saw that in my small commercial flying experience) that
* short- or middle-haul flights delayed 15-30 minutes on take-off,
* long-haul flight delayed 60-90 minutes on take-off,
are nearly always able to land on-time, effectively "working out" their initial delay during flight, by flying faster etc. What happened or could happen here? | 2019/08/27 | [

The plane probably circled as long as fuel margins would allow, rather than sit on the ground in a long line. | re 'working out delays'
The flight uses an operational flight plan which shows the routes (waypoints), speed, altitudes. There are usually some compromises made, a shorter route may cost more (overflight fees) and a cheaper route may take longer. The company will usually select what is best ie more economical with flight time acceptable.
In exceptional cases like longer delays, the ops dept may choose a higher cost route to minimise the impact (more direct route or higher cruise speed). This is usually easier to do on longer flights of course, on shorter routes there may not be much choice. |

284,600 | I haven't found a way to change my loadout, on the main menu 'soldier' tab is blacked out and there's nothing in 'store'. Can I only configure when I'm in an online match?

] | During the beta, the only way to buy weapons and accessories and to edit your loadout is during a game.
While you are on the respawn screen, you can select a class loadout, then you can use your controls to move inside that loadout and select things like your main weapon, side arm, grenades, tools, etc..
Then you press the *correct button* \* to access the sub menu, inside this menu you will find new items you can purchase with your war bonds and you can also select purchased items to spawn with.
The same way applies for vehicles, which is annoying because this means you have to wait for vehicles to be available to be able to customize your loadout.

Then that setup will stay consistent throughout matches (i found that if you dont change it on the website, then the loadout resets from what you change it in battle and you have to redo the whole process over and over which gets frustrating).
The funny thing is, the instruction video (how to change loadout) shows you a button that should be between the server browser and server favorite buttons (in the same row on the starting page when you load the game). But its nowhere to be found oddly enough. Really wierd. |
1,671 | If it is illegal to download videos and audios from youtube due to copyright reasons, why are there so many youtube to mp4 and mp3 download websites online?
For example <https://freevideotomp3.com//>, one could reason about them just providing a way for users to download youtube content, letting to these users the responsibility to decide whether they will use it for downloading free or copyrighted content.
However most of these websites (just as youtube-mp3) have an internal cache which stores the already processed mp3/mp4 files, so if users download copyrighted material they will store in their server copyrighted content, thus illegal distribution.

] | **It is, in most jurisdictions, not a crime to download YouTube videos.**
For criminal law, the answer is that it is not illegal. In many jurisdictions, downloading music or video of any kind from the internet is not a crime. Thus, police has no power to punish you for downloading, and even less power to shutdown such "downloader" websites.
YouTube's Terms of Service seem to disallow such downloads so YouTube has the right to terminate the agreement with the downloader. They may prevent you from viewing any more videos, for example. However, I think Google does not even have a technical measure in place to do that.
Google is not interested in preventing you from using YouTube (its servers can handle that) and that is pretty much the only punishment it can use.
Google could use the Terms of Services to say that the downloader-websites are breaking them and thus should not have access to YouTube. The websites could be sued for breaking the Terms of Services (and the court could order them to stop) and Google can block those websites from accessing YouTube by technical measures. It appears [it did so](http://www.youtube-mp3.org/help-us) in at least one case.
**Google could sue you (or the websites) for advertisement revenue loss, but it is unlikely.**
In theory, Google loses advertisement revenue from the video playbacks you would have done on YouTube but did not play because you downloaded the video and played it offline (contrary to the Terms of Service). Google might attempt to sue a downloader website on this basis and try to make it give it money. It would be difficult for Google to prove that it deserves such money, though.
I cannot imagine how it would prove that "you would have played the video online, again, with advertisements, if you didn't download it. Note that when you replay a video from browser cache, advertisements do not replay.
**Why Google doesn't sue downloader-website more often? It's expensive.**
Google could pay a lot of money to shut down a website via court order but if it really wants to do so, they can apply a technical measure (such as IP block) instead. It is much cheaper and has the same effect.
**This may change in the near future.**
There's a some talk around about European court rulings and directives that may change this. It is quite possible that in the near future, even viewing illegally uploaded music on YouTube will be criminal. I find this doubtful because of the difficulty of proving knowledge ("How was I supposed to know that it wasn't an official clip?").
As for whether downloading to a file (as opposed to downloading to the browser cache) will become criminal, I really doubt that. | YouTube has commented on this topic in the past, stating (paraphrasing) that due to the amount of information that is uploaded to their sites, it simply cannot monitor whether the files are copyrighted with any accuracy or totality. They do have systems in place for standard due diligence and once they are made aware of copyrighted material, whether through trolling via programs designed to identify it, or by report from actual human beings (employees, artists, the public) the material is removed. That being said, it is often replaced in short order by another user or the same with another "handle". YouTube is not offering the material for consumption, they are only a clearinghouse, such that so long as it is in their disclosures are clear that the practice is not only frowned upon but is a definitive violation of their terms and conditions of use that result in the loss of account access, and they do actually, practice due diligence to help combat it, their exposure is limited at best. The individual who downloads copyrighted material has exposure, as does the individual who uploads it, but it would hardly be worthwhile to prosecute ( civilly or criminally) individual infringements as it is about as common as speeding. |
