Whether you are talking about massive or massless particles, their motion helps determine the gravity they cause.
If you want to see how the velocities and accelerations of two massive particles affects their mutual gravitational accelerations, look at the [Einstein-Infeld-Hoffmann equations](https://en.wikipedia.org/wiki/Einstein%E2%80%93Infeld%E2%80%93Hoffmann_equations).

Physics is a scientific discipline where observations and measurements are fitted with mathematical models which describe existing data and successfully predict new values for new boundary conditions. When this happens one says that the model has been validated.
If new experiments and observations should falsify the model, one will have to re-examine the assumptions and even search for a new model.
In the particular case of gravity, [Newtonian gravity developed](https://en.wikipedia.org/wiki/Newton%27s_law_of_universal_gravitation) from fitting mathematically observations and measurements up to two centuries ago, using [classical mechanics](https://en.wikipedia.org/wiki/Classical_mechanics) , and a single axiom/law , Newtons law.

This means that even for [using the GPS system accurately on earth](http://www.astronomy.ohio-state.edu/~pogge/Ast162/Unit5/gps.html), one needs general relativity corrections to the first order orbits of the Newtonian model.
It has to be stressed that a new physics theory describing the same data, **must** be consistent at the limit of overlap with the old theory, because the old theories are a mathematical mapping of a great number of data, and are a type of a boundary condition to **any** new theories, there has to be consistency in the overlap regions of phase space, and the definitions of variables.

In classical theory, even with quantum mechanics, photons have no mass, so have no Newtonian attraction.
In GR masses are the manifestation of the [tensor](https://en.wikipedia.org/wiki/General_relativity#Einstein's_equations) defining the energy and momentum distributions of the system under study. Thus for the mathematics of GR as light has energy , it contributes to the tensor and thus distorts space, and this has been observed in astrophysics.
Force has no meaning at the energies and masses of GR. It is a consequence of the space distortions that can be derived from the mathematics of GR.

Here is a list of the abilities that light has, and after each ability in parenthesis there is the name of the ability.
1. Light has the ability to pull a nearby massive object towards itself. (attractive gravity)
2. Light has the ability to pull a nearby massive object in its direction of travel. (gravitomagnetic induction a.k.a frame dragging)
3. Light has the ability to not pull nearby parallel light towards itself. (attractive gravity and repulsive gravitomagnetism together)
4. Light has the ability to pull nearby anti-parallel light towards itself. (attractive gravity and attractive gravitomagnetism together)
5. Finally, I think two passing anti-parallel light pulses should induce some gravito-motive forces on each other, but after they have passed they should be like before the passing, except for some small change of direction.

] | I doubt you'll find ransomware source code floating around in the general public. I'd guess there is code out *there somewhere* but I wouldn't risk visiting shady sites on the "Darknet" (I really hate that term).
(Un)fortunately, ransomware is not very complex. For a university project, simply encrypting and replacing files in ~/Documents is probably good enough. The trick is making the decryption key only obtainable through you.
Encryption:
1. Generate Symmetric Key **K**
2. Encrypt all files in ~/Documents with **K**
3. Send **K** to Server
4. Erase all traces of **K**
Decryption:
1. Obtain **K** from server.
2. Decrypt files with **K**
I know that notorious ransomware use Asymmetric Encryption, but it actually isn't necessary at all. For example, improperly implemented RSA by [CryptoDefense](http://blog.emsisoft.com/2014/04/04/cryptodefense-the-story-of-insecure-ransomware-keys-and-self-serving-bloggers/) actually made it **easier** to write automated decryption tools, because they didn't realize that a Windows Crypto API keeps local copies of generated RSA Private Keys. Putting blind faith in a crypto system won't make it secure. What's important is that the decryption key is not recoverable on the system. Whether or not this is done by zero'ing memory or encrypting **K** with an RSA Public Key really does not matter. | No. There is not and I am quite sure there will never be: imagine nuclear weapons are available to buy in the shop.

Modern ransomware does not typically use just a symmetric key or operate via the mode described in some of the other answers. A method of operation more closely related to "real world" ransomware looks like this:
* Generate a unique asymmetric key pair on the ransomware server
* Send the public key to the victim machine for use with ransomware client (already lying in wait on victim machine)
* For each file in list of files to encrypt:
* ... generate random symmetric key (e.g., AES key)
* ... encrypt file with random symmetric key
* ... encrypt symmetric key with asymmetric public key
* ... replace file with symmetric-encrypted file concatenated with public-key-encrypted symmetric key

1,355,647 | I've heard of events and SO answers "bubbling up", but what has all that got to do with bubbles? | 2009/08/31 | [

] | Event bubbling is the idea of information moving up through a deep structure, when proper design dictates that normally information should only flow downward.
In very basic terms, think of a single object. Properly designed, this object should only know about its own child objects. It should have no direct interaction with its parent. Its children and parent objects, in turn, should follow the same rules. In effect, this means that information can only flow downward - a parent can invoke a method, send data into or extract data from its child, but the child cannot forcibly do the same to its parent.
Think of what happens when you blow an air bubble underwater - you don't have to *push* the air towards the surface - you simply release it and it moves on its own. The same concept applies to event bubbling - deeper controls simply "release" their information - usually via an event - and it "floats" up the chain without directly invoking anything.
With regard to a website like Stackoverflow (or practically any kind of site), the concept of bubbling is the same. Obviously each individual post ought not directly put itself on the home page, but when a single post has been updated, that event is released from the deepest point in the hierarchy - a single post - and floats up to eventually the top level, where it is dealt with (choosing whether or not to display on the home page). | If you are asking about the term, I guess it is an analogy to an event 'bubbling' up to the top, like an air bubble does in liquid.
If you are asking what event bubbling is it is an event that is caught by one object that will refire it to any other objects that are listening to it.

<http://www.harbar.net/articles/sp2010ups.aspx> | I actually fell into TWO traps when I provisioned SQL for my SharePoint 2010 farm, and both traps were not very well documented either my Spence Harbar's famous UPS article (mentions it) or by Technet (no mention AFAIK). First of all I set up a named instance of SQL Server, like SERVERNAME\SHAREPOINT. Then I used the SQL server's FQDN (servername.domain.name\SHAREPOINT) name when I installed SharePoint, which is another thing the UPS can't handle.
I tried a lot of troubleshooting, but in the end was forced to reinstall SQL and SharePoint. Had a lot of trouble with uninstalling Office Web Apps and SharePoint and in the end I'm stuck with a trouble-ridden SharePoint install and only a few days until deadline. Oh well, it could be worse.. :)
Anyways, DON'T use SQL named instance OR SQL FQDN if you think you'll ever provision UPS, that's my point. Both work perfectly in all other scenarios, but you never know, do you.. :) |

According the paper, the interference patterns that arrive at D1 and D2 are shifted by pi.

Therefore, isn't it equally valid to say that the interference is always there, also for the photons that arrive at D3 or D4? We just don't detect it in that case, because we only look at only one of the possible paths and don't combine them together. It is the beamsplitter BSc for D1 and D2 which makes the interference pattern visible. That is, no information is erased, and there is no need to transfer information from D1/2/3/4 to D0.
**Edit:** expressed in a different way: if I would remove the D3/D4 mirrors, and let all photons go through to D1/D2, it would clearly show that there is an interference pattern in D0 for all photons.

Have you checked what this m is in the famous equation? m is the [relativistic mass,](http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/tdil.html#c3) and is not an invariant.
[](https://i.stack.imgur.com/tsZ3y.gif)
It depends on velocity, and kinetic energy depends on velocity too,it is what happens to the inertial mass, the mass in F=ma, at relativistic velocities but a useful formula only for space ships going at relativistic velocity.
In particle physics the the concept of relativistic mass is not used because of the confusion in terms it introduces. One works with [four vectors](http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/vec4.html) of energy and momentum, where energy and momentum are conserved quantities and $m\_0$ is the invariant mass of the particle or system of particles described by the four vector, which does not change.

Hi,
i have searched for this around the web and i can't find the right answer for my question.
basically i want to know if i can get better performance with nginx than with apache (in php apps), and i'm not involving static content (where i know nginx is better).
the sites are a widely collection of scripts with a lot of variables, using old not OOP oriented code and new websites using classes and smarty. the sites are very dynamic, changes parts in each request.
i want to avoid suing nginx for static content and apache for php, so for that i;m asking, if it worth the transition in performance terms.
my main confusion comes where i have seen benchmarks using wordpress and wp-supercache plugin, that could make it better for nginx than a custom sites with the features i already described. i have seen other benchmarks that just not show a big difference between them (around 5%)
thanks in advance for any help :D

] | What do you mean by 'performance'? Does it mean maximum throughput on a very busy server or does it mean fast pageloads for individual pages?
Apache is rarely the limiting factor (some settings may improve performance 'tough). Usually the real load lies with php or mysql, and then usually badly constructed queries or useless work.
Where nginx shines compared to apache 1 and 2 is in handling many concurrent connections (idle or busy). It also makes server paradigms possible that are not available on other webservers. It does not magically improve the performance of PHP/MySQL.
Stopgap measures probably more worth your time than nginx are a php opcode cacher (apc) and the mysql query cache.
Other than that I'd start profiling and fixing the code.
For faster pageloads you will have most benefit from modifying the way the site works, see for example the yahoo performance blog. | Considering the breadth of applications of PHP, as well as any other web-serving scripting language, each website can behave very different.

Pursuit of Happiness is like something which we have to get and it is a kind of thing which must be pursued; we don't simply get it.
In the title itself it suggests that Chris pursues the happiness because what we do in our life for earning ultimately our goal is to get the happiness in the end. Also, happiness is kind of something which can be started from the inside of yourself. |

42,397 | **Is it possible to defeat software keyloggers?**
I remember reading long ago about programs run from a USB which will defeat keyloggers.
The software works (if I remember correctly) by intercepting keyboard events to the system, and randomly replacing your keystrokes with random keys, and then counteracting the randomness with a backspace or copy and paste type algorithm.
Does this kind of software exist, and is it reliable? I'm sure a dedicated attacker could read his/her logs, but for use in a library or other public location this approach could seemingly work. | 2013/09/13 | [
"https://security.stackexchange.com/questions/42397",
"https://security.stackexchange.com",
"https://security.stackexchange.com/users/30108/"
] | The generic issue with such countermeasures is that they defeat only *some* keyloggers, and are themselves defeated by the next generation of keyloggers. In this case, it would be easy for a keylogger to take into account the backspace events (the keylogger sees all keyboard events, so in it sees backspaces) to rebuild the actual password. In fact existing key loggers should already do that, because *human users* use the backspace key occasionally, too !
Another generic issue with an anti-keylogger software is that it is *software*. A software keylogger, in order to enact its malevolent functionality, must intercept keypress events, and this requires privileged access to the operating system, at least administrator-level. An evil piece of code which obtains such access will not necessarily stop there; it may also scan for the launch of known anti-keylogger software and deactivate it. Malware and virus do that in general, against anti-malware and anti-virus software.
An additional reason why a keylogger would block out your envisioned anti-keylogger software is that keylogger writers generally dislike competition -- if they find other keyloggers from their fellow keylogger writers, they promptly kick them out. Your anti-keylogger software, from the outside, really looks like a keylogger, since it intercepts keypress events; it is then likely to be deactivated by another keylogger which just wants the monopoly of key logging.
Therefore, if software such as you describe exists at all, then it cannot be considered as reliable. It might enjoy some partial success against a few keyloggers, but this won't last. | About the only consistent protection - other than all the usual precautions about protecting your computer from malware - is a **hardware two-factor authentication dongle** (à la SecureID).
This way if a software or hardware keylogger exists, your security has collapsed into one-factor authentication instead of *zero*-factor authentication.
The equivalent of a hardware dongle can be created by having a seeded pRNG on a mobile device. The Battle.Net authenticator for example. This assumes the malware is only on one of your computing devices - not both.
In either case, this protection from keyloggers is website-specific (or single sign-on equivalents) as the two-factor authentication needs to be recognised on the server-side.
Protecting the decryption of assets residing on the same device as the malware is impossible without some seriously [compartmentalised hardware modules](http://en.wikipedia.org/wiki/Trusted_Computing), or a weak malware infection to begin with. |

] | I'm going to make a few assumptions here, I'm going to assume that by I2 you mean the current flowing to GND from the voltage regulator.
In a linear voltage regulator (I've used an L7805 as the example for this answer) your output current is always going to be:
Where I3 is your output current, I1 is your input current and I2 is the current flowing to ground, also known in the datasheet as the **quiescent current**. This quiescent current value changes slightly depending on your application but it is mainly a set value. For the case of an L7805 it is ~6mA.
Quiescent current is defined as the difference between the input an output currents. This is the value that I think you're after. Lower the quiescent current, higher the efficiency, although apart from specific or close to tolerance applications it is usually considered negligible | As the 78xx series is based on a linear regulator design, the input current required is always the same as the output current. As the input voltage must always be higher than the output voltage, this means that the total power (voltage multiplied by current) going into the 78xx will be more than the output power provided. The difference is dissipated as heat. This means both that for some applications an adequate heatsink must be provided, and also that a (often substantial) portion of the input power is wasted during the process, rendering them less efficient than some other types of power supplies. When the input voltage is significantly higher than the regulated output voltage (for example, powering a 7805 using a 24 volt power source), this inefficiency can be a significant issue. |

However, you get incidental revenue from every darn thing. Say you buy a parcel of land for a future distribution center, and the land has a USDA conservation easement (in which USDA pays you a small amount not to farm it). But, the plans do not pan out that year. You take the USDA income with a smile, it is 0.002% of your total revenue.
But now, you are writing your annual report to stockholders in which you describe your revenue *in a limited number of words*.

Other random income sources are things like easements, sublets (buying a strip mall to get the anchor store location, or CVS at Target), tax abatements or tax credits (say that rooftop solar system you installed in the San Bernadino location), etc.

] | Are you asking "What specifically does Target mean by Other Revenue" or are you asking "What might a company like Target mean by Other Revenue"? Given that Other Revenue appears to be only 1.5% of Sales, it is unlikely that Target provides a specific breakdown of the types of other revenue they might receive. Typically, companies would provide more detail in annual reports than in quarterly reports. So if you go back to the [2021 annual report](https://investors.target.com/static-files/836c7937-1e68-4445-aa98-9a19448f4334) and go to page 11, there is this paragraph

At least some of their Other Revenue comes from CVS leasing space in Target stores for pharmacies and clinics. Realistically, they're also getting revenue from these other partnerships.

I suspect the same character making multiple moves in a row is boring and goes against the **fill the characters' lives with adventure** agenda. | ### Make the game more narrative!
Even though you have turns, don't forget that in a round of combat all actions are contemporaneous. (In some rule-sets the terms "turn" and "round" have their meaning swapped... by the way the idea is the same...)
In a round robin approach you can just collect all players' actions in a turn of combat and just explain what happens accordingly to what you (the GM) decide for NPCs/Environment to happen.
Furthermore, players must always describe their in-game actions in order for a move to be triggered; for example, it's not permitted to say merely
>
> I perform **Hack and Slash** move on target Xavier.
>
>
>
but maybe something like
>
> *I attack Xavier with my broadsword paying attention to what Lucy does.*
>
>
>
Acting like this, the player can express his will to interact with Lucy the following **turn**.
It's enough to keep in mind that you are **roleplaying** and not *playing a video game*. |

I suspect the same character making multiple moves in a row is boring and goes against the **fill the characters' lives with adventure** agenda. | I try to imagine the narrative of combat as being a bit like a soccer game. The spotlight is passed back and forth and sometimes intercepted. You want to make sure that everyone gets a chance, but remember, the GM's mandate is to always ask "What do you do?" and to be curious about the situation. Think about who each action might affect and ask them how they respond. Luckily, you only have half as many active members of a battle to think about - the monsters only go when the PCs look to you as if to say "well, what does the Ogre do now?" or when moves indicate they get to do something. The players will pick this rhythm up and start jumping in to have their say, too. |

] | Domain rename with Exchange 2007/2010 is not supported by Microsoft. If you want to go this route, you will not be able to get any support from Microsoft, and there is a good change that your infrastructure will be damaged in some way. Most sites I have read on this say NOT to do this.
So this leaves you with three options:
1)Do Nothing - This is the easiest of the three options. If the external domain is not something people are going to go to, then there is probably nothing to worry about. There may be some issues in getting UC/SAN certificates for Exchange, but the only issue I am aware of will be a security warning in Outlook when you're using the program inside your firewall.
2)Remove Exchange, then do a domain rename - I don't know what other AD-aware/AD-connected applications you have, so this may not be an option. How this works is that you take a long outage, back up your Exchange databases, remove Exchange from your environment, rename your domain, and then re-install Exchange and configure your environment. This would be a lot of work, and you would have no email during this outage. You would also need to extensively document your Exchange environment so that it is reconfigured with the same settings.
3)AD Migration - Create a new Active Directory forest and migrate all of your AD-objects to this domain. This will require the most work and the most testing to make sure that a migration doesn't break any of your applications.
3a)New AD Domain in the same forest - Some of the Microsoft material that I have read for my MCITP states that you can have discontiguous DNS naming structures in the same forest. This means that you can have one Active Directory forest with domains xyz.com and abc.local. This is a supported configuration for Microsoft Exchange 2010 (see <http://blogs.technet.com/b/exchange/archive/2009/10/27/3408616.aspx>), and it should allow you to solve your issue without a large-scale migration to a new forest.
If you decide to make any major changes to your AD environment, I would recommend contacting a Microsoft partner to go over your scenario in greater detail than what you can provide here.

3. If i then click on my app icon again, My lifecycle methods are called as if my app wasn't started, i.e. onCreate, onResume etc. gets called again!!
I have no idea why this is, it doesn't happen on Galaxy2 or the Note, which i just tried, i get the "expected" lifecycle calls there.
Anybody got any thoughts? To me it looks like something is broken in the phone, but i'm just one guy and i haven't found any other reports, so i can't understand how that could be the case...

The only easy place to build inside our solar system is earth. Everything else kinda sucks. We could build a colony on Mars or some of the moons of Jupiter but it's pretty far from ideal. The only reason we consider it at all is because there aren't any other options we can reach.
If this event got humanity in contact with other aliens, and provided FTL technology, then it may simply be that we don't return to our old home because Earth has been made uninhabitable in some way and ***there are so many better options now.***
Turns out the universe has loads of Earth-style planets with no intelligent race living on them so there's simply no reason to go build a domed Mars colony or deal with hostile atmospheres or cold climates. Just pick one of thousands of known, hospitable, unclaimed, Earth-like planets and starting the colony is far easier and cheaper. |

No, not *literally* - that takes too much power. But they have some basic technology that can tap into the Sun's own magnetic dynamo and spin a ball of magnetic plasma around the star - basically, turning it all into one giant sunspot. A sunspot which is very carefully calibrated and aimed to beam energy out on many specific vectors to projects the aliens have going in deep space.
To the rest of the cosmos, the Sun is now a brown dwarf perhaps occasionally eclipsed by frozen planets with little if any gaseous atmosphere.
The aliens do not believe in *enslaving* humans. The humans should be more than willing to spend their lives working for a small fraction of the energy they once thought of as falling free from the sky. A policy they can argue is entirely in line with native traditions, as several centuries of Earthly capitalism had assigned commons lands, unknown natural resources, even drinkable water to the powerful in much the same way. |

] | The answers all suggest multiple plausible ways to render the Solar System uninhabitable, but suffer from some flaws, such as requiring a long time frame to work, or require a great deal of resources.
I will refine the process and suggest the aliens simply have to fire one RKKV (Relativistic Kinetic Kill Vehicle) into the Sun. Striking the sun with that amount of energy and using the extreme speed of the RKKV to deliver the energy deep into the Sun, many processes will be disrupted and the Sun will likely emit massive flares and other radiation events which will scour life from all exposed surfaces. Since the Sun will be unstable for years, there is really no hunkering down and waiting to fix the blasted surface installations, especially since we are talking about the sorts of flare events which would strip large portions of the atmosphere from the inner planets. Larry Niven's short story "Inconstant Moon" describes what such a scenario would look like from Earth.

As a possible bonus, after the flares settle down, the Sun may also go into a Maunder minimum, producing less energy and making any sort of biological or industrial recovery even more difficult.
Even K2 civilizations have limits, so being able to deal with the opposition using only one RKKV is much more efficient than trying to strike every planet, moon and free flying object in the Solar System. | #### Spheres of cobalt 59 orbiting the sun

] | Let's turn our thinking around. Instead of asking, "how could alien attacks send humanity into a diaspora?" we can ask, "what would aliens do if they *wanted* to scatter humanity like this?" Say, for instance, the aliens don't want to permanently ruin the worlds that the humans have colonized (because those worlds could be used by the aliens down the line), but they want to keep the humans off of them for a while.
I've come up with a machine that could do the trick. It's a massive, self-powered vehicle the aliens have developed, which burrows into a world's surface once it lands on the least-defended area of the planet. Once deep in the planet's mantle, it sends out extremely powerful EM pulses constantly, which disrupt electronics all over the planet but dissipate harmlessly at larger ranges.
Any human habitats on the planet will immediately lose life support and become uninhabitable, forcing an evacuation or worse. The humans can't just move to another location on the planet, because these EM pulses don't stop. Perhaps with some ingenuity, they could build Faraday-cage-enclosed habitats, but it would be dangerous setting that up in the first place while that machine is still running, given that all of humanity's habitat-building tools are themselves electronic.
But couldn't the humans just destroy the device, you ask? Well, sure, maybe they could get a high-power enough laser from far away enough in space to vaporize a hole all the way down and destroy it, or something like that. But that takes a lot of time and a lot of resources. Maybe some governments were working on just such a solution, and the aliens eradicated them before they could finish.
These planet-wide EM-producing digging machines are, of course, very expensive for the aliens as well, so it makes sense that they only sent them against the main human settlements, and have spared the scattered outposts. | **Rocks**

A dead star swinging by the very edge of our system could easily dislodge of a few billion kilometer long pieces of ice. Just for good measure there could be ancient dormant prions, as mentioned in a previous post, that inhabit them. Fast forward a bit and you literally have an entire solar system getting pelted nonstop by large glaciers filled with deadly viruses/bacteria, or whatever you want them to be, quickly causing the entire solar system to go to shit.
This would take care of pretty much any base that's not heavily armored, even if it is, just chuck a few hundred abnormally large iceballs at it.

After all, if I am granted access to the video, and now I'm playing it and setting it to whatever the maximum resolution is, assuming different resolutions are behind different paywalls, I could just open up OBS, record my desktop at 5000 kbps, and get an amazing rip - and encryption would do absolutely nothing to hinder me, because I'm totally bypassing the fact that I can't easily download it directly.
So my question is, why bother with encryption on videos? It wouldn't prevent automated video farming as long as proper user credentials are presented either I think? And furthermore, there's a sort of downside in that all the encryption technologies as far as I can find available for web usage has compatibility with one device class or another, such as RTMPE not working on iOS, which is pretty well used. I presume there would also be more battery life issues, as I tend to run out of battery much faster when playing Flash videos rather than HTML5. So, why not just authenticate and stream it straight up over, say, html5 without any encryption? | 2014/11/28 | [

] | The hardware infrastructure used for A series VM is not suitable for D series VM. It might be possible that the cluster where the VM is hosted, has the hardware configuration required for creating A series VM alone.
However if you would still want to change from A series to D series VM, you will have to export disks and create a new VM using the previously saved disks.
Going forward as a workaround: when you create your very first VM in your Cloud Service, be sure to specify one of the D-SERIES size even if you do not need it immediately. Doing this, your Cloud Service will be “tied” to a cluster that will support both A-SERIES (except A8/A9) and D-SERIES, then for all the future VMs contained in the same Cloud Service. Now, you can create additional A-SERIES VMs and mix together in the same Cloud Service. If you do not need the first D-SERIES VM, you can now safely delete it. | If the D-series machines are not available due to the cluster, you can always delete the vm (preserve the disks) and create a new VM of the D-series and attach the existing disks to that system.
When you create the new VM, choose the option to 'create from template' and the select your OS disk from the 'My Disks' section. Then attach all the data disks to the VM once it's provisioned. |

53,692,576 | I'm developing a web application where the backend, developed in spring boot, consumes data from a public API that returns data in JSON.
The search is done through terms, full-text (like a google), the backend receives from the application frontend to the user's query, which in turn searches the public API, waits for a response, handles the information and sends it to the frontend.
I wanted to implement the caching system in the backend, Spring Boot.
Basically, before the spring boot makes a call to the API publishes and wait for the response, it checks on a key/value system if the search has already been done in the past, if yes, return what is in the value of the key.
The caching system:
* Key: terms of search, Value: json with API public response.
* It has to persist data, not be volatile.
* It has to be a key-value search (cache).
* It has to be updated by a system other than the described one that updates the data of the cache, verifying if the data was changed in the base (Public API).
Initially I thought of using a NoSQL database, such as mongoDB. But after investigating better, I came across Redis. What do you think is best?
I would like to ask some suggestions to implement this architecture. I'm not sure how to implement it, I doubt both Redis or MongoDB or other.

If you need to protect your backend from multiple executions of the same query, you can use [Spring Cache](https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-caching.html).
It supports different providers including Redis and has [evict mechanism](https://docs.spring.io/spring/docs/5.1.3.RELEASE/spring-framework-reference/integration.html#cache-annotations-evict) | You can use MemCache. It's ready system for caching. |

Signing Strategies
Some aspects of application signing may affect how you approach the development of your application, especially if you are planning to release multiple applications.
In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications. There are several reasons why you should do so:
* Application upgrade – As you release updates to your application, you will want to continue to sign the updates with the same certificate or set of certificates, if you want users to upgrade seamlessly to the new version. When the system is installing an update to an application, it compares the certificate(s) in the new version with those in the existing version. If the certificates match exactly, including both the certificate data and order, then the system allows the update. If you sign the new version without using matching certificates, you will also need to assign a different package name to the application — in this case, the user installs the new version as a completely new application.
* Application modularity – The Android system allows applications that are signed by the same certificate to run in the same process, if the applications so requests, so that the system treats them as a single application. In this way you can deploy your application in modules, and users can update each of the modules independently if needed.
* Code/data sharing through permissions . The Android system provides signature-based permissions enforcement, so that an application can expose functionality to another application that is signed with a specified certificate. By signing multiple applications with the same certificate and using signature-based permissions checks, your applications can share code and data in a secure manner. | On the Market the really important things are package name and versioning. If you try to upload two different package names for the same app, you'll drop in a grey zone full of pain :(
Second one, if you try to upload twice the same app forgetting to update version, the Market will refuse your upload and you have to rebuild your app changing the version.
Finally, I use the same keystore and the same signature for my apps without issues :) |

Branching and merging is kind of a pain in the ass in SVN; it's annoying enough that it's not worth the time to create small, short-lived branches for quick feature additions, bug fixes, or experimentation, but merging is also annoying enough that it's a pain to create long-lived branches as well.

A DVCS also doesn't require a central server; when using SVN as a developer, you have to create a local repo to push into, which isn't a requirement with Git, since every repo contains the full history.

] | It is perhaps worth looking into more historically established prion diseases in noncarnivorous animals, like sheep. If prion diseases were *only* transmitted by consuming prion-rich brain tissue, then they should be extremely rare (produced via unique misfolding events or mutations in affected individuals) or completely absent in wild herbivores and domestic herbivores which are not being fed meat meal.
In fact, I mention scrapie because it [predates the practice of supplementing livestock feed](https://www.researchgate.net/profile/Heiner_Fangerau/publication/23415231_The_early_history_of_the_transmissible_spongiform_encephalopathies_exemplified_by_scrapie/links/09e415088379596a2f000000.pdf) with meat-derived protein. (The first documented mention of the disease dates back to about 1772 and mentions that the disease is about 40 years old at that point.) As it happens, the earliest mention of livestock feed or feed supplements being composed of meat and bone meal I can find dates to [about 1890](https://www.researchgate.net/publication/291389679_Review_of_the_feed_industry_from_a_historical_perspective_and_implications_for_its_future). Prion diseases also appear in wild populations of elk and deer in the form of [Chronic Wasting Disease](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3309570/), currently a big problem in the northern US and Canada, as well as in cattle and sheep.
**So how did scrapie come to be such a problem for European sheep farmers?**
Well, for one thing, scrapie (and CWD) can be transmitted via [ectoparasites](https://www.researchgate.net/profile/Omar_Lupi/publication/7848496_Risk_analysis_of_ectoparasites_acting_as_vectors_for_chronic_wasting_disease/links/570d210108aed31341cf7129/Risk-analysis-of-ectoparasites-acting-as-vectors-for-chronic-wasting-disease.pdf). But the most common culprit probably lies in the soil. It turns out that [infectious prions can survive for *years* in soil](http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0000435) once they're deposited. Not only is the decomposition of a carcass a way to infect the soil with the misfolded prions, but CWD proteins are also [present in the excreta of infected animals](http://pubs.acs.org/doi/full/10.1021/es903520d) and even [antler velvet](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2687044/).
This is a problem, because both scrapie and CWD can be acquired simply by [consuming infected soil or grazing on grass containing it](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3323154/). This is most likely the most common way that these prion diseases are acquired naturally--not cannibalism at all, or at least not the sort we commonly think of! It's a simple fecal-oral route of transmission, albeit one with an alarmingly long potential incubation period. | An individual (animal or human) acquires a prion disease when they consume meat that contains prions (proteins that are mishapen enough to drastically change their functionality), which subsequently causes proteins within the individual to misfold into the same shape as the prion, resulting in a whole slew of problems.
**As of right now, there is little knowledge of where prions come from/how they're formed. Also, there is little knowledge of how inter-species infections/transmissions occur.** Researchers are currently investigating various combinations of inter-species transmissions, such as humans eating infected horse meat, or cats eating infected chicken meat, but still know only very little about this phenomenon.
To say which species have higher rates of prion disease when looking at a cannibalist communities within that species, I don't think we're anywhere near close to making those conclusions, and the same goes for inter-species transmissions.

Actually, "nope" means "no," but only in the sense of the opposite of "yes." Therefore, you might use it to answer a yes-or-no question in the negative, but you would **never** say, "*We found nope errors during the inspection*," or "*There was nope way Dave would ever surrender*."
That said, "nope" is informal, and should only be used in writing in the most informal of contexts. | J.R. is correct to note that *nope* occurs only as a one-word answer to Y/N questions, and not for other uses of *no*.
The final "pe" in *nope* comes from the way it is pronounced, ending with **firmly** closed lips to signal the end of the word, answer, utterance, and discussion.
The "p" part is produced by closing the lips, and the silent "e" comes from the English spelling system, which requires it there to keep the pronunciation of "o" as tense /o/ even though it's followed by (what sounds like) a consonant.
Similar reasons account for *yup* as a variant of *ya ~ yeah*, which needs no final "e" because the vowel is not tense. |

2)open the applications using exec() (before doing so checking what kind of operating system the user use and create the appropriate error handling)

] | In short, you can't do all that. You can do some of that. Remember, with HTTP the user is in complete control, and you can do nothing "on the user's machine". If you could, that would be called "a dangerous security exploit" and would stop working as soon as the various browsers' coders got to it.
You can send the output to the user with an appropriate MIME type, that will open the editor of your choice. You can even invent your own MIME type to do that (the user must install the editor by himself).
Then the user will save the text on his machine. You can't save on a remote machine (not in all editors), since it is not a "save", it is an "upload" that you want.
Finally the user can recover the file he or she just saved, and submit it to you via a POST form, for example.
Frankly, where I live we call this "how to put one's ass before other people's kicks". Just think of all the possible editors, each maybe with its own format: if the user (un)knowingly chooses something weird such as "Save in Word 2015 Extra Format (Compressed)", and uploads the file to your server -- are you prepared to understand the file format and do something meaningful with it?
A very common alternative is to implement any one of several Rich Text Editors in HTML - there's CKEdit, for example, or TinyMCE, and so on. They will let the user produce clean HTML and upload it on your server automatically. | What you're trying to do is impossible. PHP is server-side and it has no control over the client, it can only send it a sequence of characters to render (the page that gets displayed).
There are javascript-based rich editors such as CKEditor and TinyMCE which you can provide for the client to use, but that's about as far as you can go.

You will only have to worry about the access to the CMK [which you can achieve using IAM access control](http://docs.aws.amazon.com/kms/latest/developerguide/iam-policies.html).
For a detailed explanation how the mechanism works, check the [Envelope Encryption section on the KMS Cryptographic Details white paper](https://d0.awsstatic.com/whitepapers/KMS-Cryptographic-Details.pdf).
So if you only worried about eavesdropping can be a good solution. If you are looking for strictly end-to-end encryption you might have to use asymmetric keys on which KMS can help you with too. | Aws kms does not store any data it provide you two keys
1 plain key : with the help of it you encrypt the data and delete it(key)(no need to save anywhere).

] | First, a quick nomenclature correction - checksums and CRCs are 2 different approaches trying to solve the same problem: detect bit errors occurred during data transmission in noisy channels. In general CRCs are more powerful detecting errors at the expense of more complexity.
Selecting the right error detection scheme requires some knowledge about the channel (e.g. error probability) and its noise characteristics (e.g. impulsive, bursty). There are papers out there where this problem is analyzed in detail and some guidance is given in how to select the error detection method. I suggest you trying this introductory presentation as a starting point:
<http://www.ece.cmu.edu/~koopman/pubs/KoopmanCRCWebinar9May2012.pdf>
It will give you a better understanding of the complexity of this beautiful area and provide you some links to other learning materials. | Assuming that you have a good CRC or hash function that makes good use of the bits, and assuming that the expected sources of corruption do not have some unusual characteristics that invalidate the first assumption, then you can simply set an acceptable probability of a false positive, and get the number of bits from that. Or compute the probability from the bits and see if you're comfortable with that. The probability is:
p = 2-n
where *n* is the number of bits in the check value. That is the probability that an *n*-bit check value on some random data will accidentally match the *n*-bit check value on some other set of data. |

A local drive is faster of course, which may matter to you if you store a lot of data or many files. E.g. processing thousands of images on S3 to have a new thumbnail size tages a *very* long time, since each file needs to be downloaded, processed and uploaded.

This is circular logic. No one can become used to neopronouns if they are not used. And the change from a singular to plural in the quote suggests things are hardly clearer.
Indeed this same flaw is the basis of my disagreement with comparing it to misgendering. Xyrself, a third person gender neutral pronoun does not asign a gender, and it does it reject the assigning of a gender to an individual.
Perhaps in this instance themself is serviceable and specific, but singular they while gramatically correct can be easily confused with a plural meaning, and use of xyrself as an extension of xyr is a logical requirement to increase familiarity, understanding and acceptance of neopronouns. If that is something the poster wishes to do then more power to xem. |

The (main) Meta discussion linked in the edit suggestion comment is worth a read:
[Can a user use neopronouns for any third party?](https://meta.stackexchange.com/q/340881/162704) | My opinion is that edits *exclusively* changing neutral pronouns to other neutral pronouns (including from "neopronouns" to themself) should be rolled back, as they're fairly clearly inconsequential edits. Had I noticed the edit before I noticed this meta post, I would probably have rolled it back for that reason.
Some answers to anticipated objections in this particular case:
**Changing to themself improves clarity.**
I guess the driver for this opinion is that xyrself is not an especially common word, but I don't agree that that alone justifies an edit, any more than would be an edit of "werewithal" to "means" or "apportionment" to "distribution" or any other change from a single less common word to a more common synonym.
**Xyrself is political.**
How? It's just a neutral pronoun. If the poster had attempted somehow to make their answer entirely about the pronoun or about gender politics generally, then yeah sure. But that's not what happened. If anything, it is the act of changing the pronoun that comes across as potentially political in my opinion, particularly given the fact that the context in which it was used was otherwise devoid of any gender politics. Certainly a change from themself to xyrself would be construed in that way, given they are synonyms. I don't see how the reverse change is any different.
**Xyrself is less readable**
Xy words exist in English, what's the problem?
**The use of neopronouns attracts the wrong type of attention**

and additionally is part of the editor's justification for the change. To me this is a point of real disagreement. They're entirely right that it's distracting people, not least the flagger who described the use of the word as "deliberately provocative", but I don't see why we should pander to people who think something so innocuous is provocative. We would never countenance editing out a reference to a spouse as "husband" or "wife" because it was triggering people who take issue with the existence of same-sex marriages for example, I don't see how this case is any different.
I recognise that that might give the mods a hard time if they were absolutely inundated and having to spend inordinate amounts of time clearing up such posts. If that were the case, I'd probably acquiesce on the grounds of necessity.
**The neopronoun was not referring to a specific person who had stated that was their correct pronoun**
I mean...what's the problem then? If it was referring to a specific person who had specifically pointed out that that was **not** their preferred pronoun then that absolutely should be edited...but in the absence of any knowledge and particularly in the case of a reference to a hypothetical person (as in this case) it's effectively impossible for anyone to take offense at the usage. |
4,239 | I have met with [this edit](https://politics.stackexchange.com/review/suggested-edits/29014) twice during review.
It boils down to changing a neutral pronoun to singular they. First time I thought this edit made next to no improvement (I know some other reviewer chose causes harm reason) because:
* it is a very little change (no significant improvement)
* it is quite clear that the author of the answer wanted to be like this
However, since the answer deals with UK Parliament rules which are in place for many years, from a historical perspective it makes more sense to use the singular they instead of the much newer gender neutral. | 2019/12/23 | [

] | My opinion is that edits *exclusively* changing neutral pronouns to other neutral pronouns (including from "neopronouns" to themself) should be rolled back, as they're fairly clearly inconsequential edits. Had I noticed the edit before I noticed this meta post, I would probably have rolled it back for that reason.
Some answers to anticipated objections in this particular case:
**Changing to themself improves clarity.**
I guess the driver for this opinion is that xyrself is not an especially common word, but I don't agree that that alone justifies an edit, any more than would be an edit of "werewithal" to "means" or "apportionment" to "distribution" or any other change from a single less common word to a more common synonym.
**Xyrself is political.**

The [main meta question](https://meta.stackexchange.com/questions/340881/can-a-user-use-neopronouns-for-any-third-party) top answer calls the use of a neopronoun for someone who has not requested it akin to misgendering. While I don't agree with that position, it is not relevant here because the answer does not refer to a specific individual.
The higher rated answer would agree with this edit because;
>

This is circular logic. No one can become used to neopronouns if they are not used. And the change from a singular to plural in the quote suggests things are hardly clearer.
Indeed this same flaw is the basis of my disagreement with comparing it to misgendering. Xyrself, a third person gender neutral pronoun does not asign a gender, and it does it reject the assigning of a gender to an individual.
Perhaps in this instance themself is serviceable and specific, but singular they while gramatically correct can be easily confused with a plural meaning, and use of xyrself as an extension of xyr is a logical requirement to increase familiarity, understanding and acceptance of neopronouns. If that is something the poster wishes to do then more power to xem. |
