403,997 | I sometimes encounter explanations of phenomena where only entropy is quoted as a driver, for example, osmosis, diffusion, hydrophobic effect... But can entropy ever be the sole driver of a process? I encountered 'entropic force', is it a real force? Aren't energy changes always present in these processes?
If this the case, when it comes to concentration gradiënts, these gradients 'contain' potential energy but I can't figure out where it originates from. For example, a water molecule that is a part of the cage around a lipophilic molecule is missing out on potential hydrogen bonding and thus feels a net force which is opposed. This missing out on stable interactions, feeling a force which is opposed...is what 'creates' potential energy. I can't see these things in diffusion and osmosis for neutral solutes (when the solute has charge, the electrostatic force comes into play - electrochemical potential - this feels more natural to consider as potential energy) which seem just to be random mixing... but in the case of osmosis the gradiënt is able to do work and create a hydrostatic pressure difference which proves the potential energy there since it can be converted into another subtype? The semi-permeable membrane seems essential in these phenomena for work to be done (osmosis, transmembrane potential generation in biology)? Free diffusion in bulk solution without membranes could never do work and all potential energy would be dissipated as heat?
The role of charge in all of this...
Osmosis is a colligative property, so the charge of the solute doesn't actually matter.
But when the membrane is only permeable to the solute, a chemical gradiënt can store electric potential energy over the membrane. The chemical gradiënt does work on the charged particles by pushing them against their electric potential. But what causes this push against the electric field, the difference in concentration? But this seems more of a probabilistic factor.The electric field over de membrane does negative work and the concentration gradiënt positive work?
Coming back to osmosis, the solutes gradiënt does positive work and the hydrostatic pressure performs negative work. So charge doesn't play a part after all?
What happens when equilibrium is reached in all of these cases? Zero work?

] | As I see it, the driver behind all the system processes you describe involves disequilibrium, i.e., pressure, temperature, concentration etc. differentials or gradients; and the achievement of equilibrium as a result of the process results in entropy production, that is, an overall increase in entropy (system plus surroundings) as occurs with all real (irreversible) processes. So in that sense, one can think of entropy production as a driver of processes. | All these processes are due to random events. The atoms do not "feel" a concentration gradient, but random walks will cause diffusion to even out differences in concentration. |
3,822,647 | here is my scenario:
* DHCPD machine (I cannot edit DHCPD settings)
* Machine 1
+ Boots a Live GNU/Linux and offers net-boot with TFTPD
* Machine 2

If I run DHCPD on Machine 1, everything is fine, 'cos I can setup all I need.
How could I setup a PXE environment without affecting DHCPD Machine settings?

You need a specific DHCP server where *filename "linux-install/pxelinux.0";* is properly defined. Otherwise your Machine 2 will not be able to find the necessary files and thus your PXE boot will fail.
Have a look a this (http://idoitonamac.blogspot.com/2012/03/os-x-lion-as-pxe-server.html). I now it's Mac, but you'll see that I managed to have a PXE server on one machine. | For the case where there is already in place a DHCP startegy PXE relies on the services of an extra "proxyDHCP server" that does not assign IP addresses but only provides the PXE parameters (bootstrap file name, and TFTP IP address) to booting stations that identify themself as PXE clients. |

For comparison, this is a bitmap traced and post-processed as vector (probably in Photoshop and then Illustrator), which keeps the edges of the color patches and gives it some energy:

The program at the known IP and port receives the message from the originating IP but thanks to the NAT the port is obscured (to something like 30129). The program at the known IP and port wants to send an acknowledgement and/or info to the querying program. It can send it back to the original IP and the obscured port #. But how will the querying program know what port to monitor to get it back on? Or, is there a way (this is Python) to say "send this out over port 3200 to known IP (1.2.3.4) on port 7000?

Thanks for your help. | The simple answer is you don't care what the "real" (ie: pre-natted) port is. Just reply to the nat query and allow the nat to handling delivering the result.

You will struggle to get it to align correctly, with or without VBA - each character occupies a slightly different width. **Edited** Well, it may behave better with a fixed-width font, as suggested by Tim Williams, but I still doubt that it will work consistently.

32,034 | My question is pretty much summed up in the title. My story includes a lot of narration. Narrating events, narrating character's thoughts. There are several intervals in each chapter where the characters engage dialogue, but most of the story telling is done through narration.
How viable is this for writing an enjoyable story?
Edit: just to clarify what "too much" means, there is generally more narration than actual dialogue. | 2017/12/16 | [

] | I don't think this balance matters terribly much.
The more critical measure is whether there is tension due to conflict. If your narration is describing a battle, for example, it can go on for pages without any dialogue. If your narration is describing people at high risk (trying to infiltrate a lair, for example) it can go on for pages.
It is tension that keeps readers turning pages to find out what happens on the next page. The tension is usually caused by conflict, but can also be caused by novelty. Like a character seeing something for the first time, that the reader also finds captivating. A giant alien space station or something. A living dinosaur.
It is easier to create tension in dialogue than in narration, just because the speakers can disagree, misunderstand, get confused or angry or resistant.
Thus a story that is mostly narration is more difficult for the writer to keep interesting, and you risk people getting bored or fatigued by the amount of information they are given without anything ***happening*** in the story with the characters. But if you can craft your narrations to engage people's imagination and give them a simulated imaginary "experience" then your story can be fine. | I like good narration and am annoyed by too much pointless dialog.
Actually, the dialog does not even need to be pointless. I become annoyed by dialog.
So, as a reader, to answer your question, there is **no such thing** as "too much narration." But there is, to this reader, such a thing as "too much dialog."
In my critique groups, I see some writers relying super - heavily on dialog. This is presumably because it is in some ways easier to write. (It is also harder to write well, in other ways.)
I believe many find it straightforward to type out a conversation, whereas describing an imaginary scene/setting requires, well, imagination and language. So, I have seen some writers relying heavily on dialog, and what ends up happening is the conversation is not well - anchored within a setting, and also the nuances of the conversation (the shading of words or stances of the people or contextual thoughts or subtext) are lost. I think some writers feel that the 'quick pacing' that they achieve from a crisp dialog and the 'all important white space' that one sees touted, are the goal.
The goal is a good story! Not speed and white space.
**Edit:**
I had actually read statistics on this ratio for fantasy books some months ago.

> Density: One way in which these books differ significantly from one another is in the proportion of narration to dialogue. The texts of the majority of titles are **less than 50% dialogue**, ranging from a low, narrative-heavy score of **13% dialogue** for The Wizard of Earthsea, to a much chattier 3**7% dialogue in The Final Empire (Mistborn #1)**. But the real odd-balls are Santiago, which is 59% dialogue, and **The Last Unicorn, which scores a whopping 63% talky-talk.** These two outliers seem so at odds with the rest of the group that I had to go into the text and examine it myself, to be sure that there wasn’t some kind of bug in my analysis tool, but my visual inspection did reveal an awful lot of dialogue in these two books.

1: The one month duration of auto-renewable subscriptions is 30 days or does it depend on a natural month?
Because I can only test in sandbox mode，so the duration is just several minutes...
Maybe Apple just simply calculates it like this: 2013\01\15 -> 2013\02\15 -> 2013\03\15. If so,the second issue comes up
2: For example: I buy a monthly auto-renewable subscriptions at 2013\03\31 ,because 2013\04 only has 30 days, then what is the expires\_date of my subscriptions? 2013\04\30 or 2013\05\01 or other date ? | 2013/03/14 | [

] | It's adding 1 month, not 30 days. The number of days in 1 month varies. So purchasing a subscription on 3/31 would end on 4/30.
You can use NSDate, NSCalendar, and NSDateComponents to add a month to a date and see how long it will last. More info here: [Modifying NSDate to represent 1 month from today](https://stackoverflow.com/questions/185780/modifying-nsdate-to-represent-1-month-from-today) | I can confirm this from my own app's data on both iOS and Android.
If someone purchases a monthly renewing subscription on, for example, the 15th of one month, then it will renew on the 15th of the next month, irrespective of how many days were in the month.
If someone purchases the subscription on the 31st of March, then it will renew on May 1st (because April has no 31st day, the renewal date will jump to the next available day in the calendar year - this also applies to February in a leap year, etc).
Given this, and assuming your app's primary income is from subscriptions, over time you should expect to see lower than average sales on the 31st of any given month because there won't be as many renewals. But it is no cause for concern as it is counteracted by the fact that you should expect to see higher than average sales on the 1st of any month that follows a long month anyway. Don't be dissapointed if you check your stats on the 31st of any month. |

It's crew module is more of a tea-cup than a saucer, but with two nacelles on pylons, a secondary hull made from a surplus nuclear missile and a primary hull made of scavenged titanium, Cochrane's 'The Phoenix' seems to have been the first and smallest of that formula.
<https://memory-alpha.fandom.com/wiki/Phoenix?file=Phoenix_top_view.jpg> shows clearly the crew module is attached above the narrowing of the missile's nose cone rather than being a single part of that hull. | It turns out there's not an easy way to answer this, because canon is sloppy or missing.
Oberth Class (120M? 150M?)
==========================
The [Oberth class](http://www.ex-astris-scientia.org/articles/oberth-size.htm) meets all the requirements at 120M (per Star Trek III production notes). But, as the link above notes, it's got massive logistical problems with that number
>
> If the Oberth were only 120m long, there would be only two complete decks of only 2m clear height inside a saucer of 39m diameter for the lower deck and 32m for the upper deck, respectively. The small saucer would have to include the standard-sized bridge, a computer core, quarters for 80 crew members, three cargo bays and, of course, several science labs as we expect it on a dedicated science ship. The window arrangement with the useless "skylights" for the lower deck, at the expense of some area in the upper deck, seems idiotic, unless it's something else. No need to mention that the Lilliputian decks of the 120m ship would not match what we have seen as interior sets in "Star Trek III" and four TNG episodes.

>
>
As such, the Oberth class is probably closer to 150M at its smallest, and possibly more than 200M by the time TNG rolled around.
Daedalus Class(140M?)
=====================
The [Daedalus class](https://memory-alpha.fandom.com/wiki/Daedalus_class) seems like a better candidate. They were 105M or 140M long and meet all the requirements of having distinct nacelles with pylons and a split hull design (with a giant ball instead of a saucer, but close enough). The catch is we have no official canon specs, so subsequent mentions vary, but some [official-ish sources](https://memory-alpha.fandom.com/wiki/Star_Trek:_The_Official_Starships_Collection) peg it in at 140M [which seems workable](http://www.ex-astris-scientia.org/articles/daedalus-problems.htm)
>
> [Maybe the model's windows are wrong] in order to allow the ship to be composed of 15 decks of 2.8m each, giving us an overall length of 140m. This is just a compromise, but it keeps the ship reasonably small compared to the Constitution class, while it alleviates all the problems of the 105m Daedalus. The size comparison with the NX class and the Constitution class demonstrates that the Daedalus class works well at a length of 140m.

NX Class (225M)
===============
If we're limiting ourselves to pure canon, this is probably the only acceptable winner. At around 225M, this is the smallest we can be certain meets all the qualifications.

232,253 | So, I am developing a fictitious world that is very similar to our earth. Generally, most of the continents stay the same way they are (Maybe North America is split in two smaller continents), with slight alteration in shape and size. However, these are the major changes I am considering to add.
* First, there is a landmass the size of Australia slap into where Arctic Ocean is, right at the north pole.
* Second is Antarctica's landmass at the south pole is reduced to half of its size (Or remove as much as the landmass that Arctic gains, so it doesn't affect sea level significantly).
How would this affect climate overall? I heard that with landmass at the pole would make ice cap being able to form larger, so would an "Arctic continent" cause North America and Eurasia to become colder at the top from the bigger, more firmed ice cap?
And with smaller Antarctica, would that make southern hemisphere warmer due to more water surface area and less ice cap? | 2022/07/02 | [

] | It depends a lot on what the geologic history of your world is.
On the one hand, the climatic history of the Cenozoic is almost entirely dependent on the history of Antarctica. You have a large landmass positioned directly over the South Pole where ice can build up on it, *then* you have the continent lose its connections to Australia and South America so there is a current circling around it (the circum-Antarctic current) to produce a natural cooling effect.
On the one hand, a smaller Antarctica by itself would mean that the ice age would not be as severe because there is less space for ice to build up on Antarctica. It also depends on how it separates from Australia/South America. If it's 50% the size, does it separate earlier, or does this mean it's positioned more northernly so the separation still happens in the Eocene and thus the continent may not be on top of the South Pole (and thus no circum-Antarctic current).
On the other hand, if there's a landmass at the *North* Pole, it means the same thing that happened IRL to Antarctica might happen there instead. It depends on if there is enough space for a circum-Arctic current to form around this new landmass, which would potentially cause an early ice age, which in turn would really change the evolutionary history of Earth. | **The Northern hemisphere landmasses around the Arctic would likely be a bit warmer. Antarctica would still be largely unchanged, possibly slightly colder.**
The climate is primarily driven by the sun and the atmosphere. The amount of energy being received by the planet isn't changing and neither is the composition of the atmosphere or the planet, thus the outcome is really that not much changes. There might be a slight increase in the planet's albedo (that's how reflective it is) if snow is more permanent in the north which would result in a slight increase in heat loss to space, but it's unlikely to make any notable difference as the region is reflective most of the time currently.
However, Antarctica is particularly cold because:
* It's high up and high altitude air is cold
* It's surrounded by water which stores a lot of thermal energy
* The angle of the incoming sunlight is very shallow
If none of these change, Antartica's cold climate also stays the same. It may get a little colder if it's surrounded by even more thermal storing water.
Meanwhile in the north, a continent the size of Australia would punch a pretty big chunk out of the Arctic ocean. The Arctic is currently cold, but not that cold, because:
* It's basically at sea level
* The angle of the incoming sunlight is very shallow
* It's surrounded by land, which will instead be providing heat rather than trying to take it
If you remove the thermal "battery" that is the arctic ocean, more energy that would've been stored up in that water will instead be in the land resulting in slightly higher temperatures there. |

Odds are that you want to quote a snippet from the whole code and you have to select it anyways before copying; if you want a button to copy the entire code i don't see how it can be any useful while answering since you will paste the whole block and then modify it through answer window which is as well time consuming.

] | First, I suggest different tags. It sounds like you're really interested in offloading searching to a server in a cryptographically secure way (such that the server doesn't have access to the plaintext and such that the client need not transfer the entire index).
Issues:
* An attacker being able to figure out which words are in the index (and which are not) could be an issue for you. You should state whether it is as a part of your requirements.
* An attacker being able to figure out which items in the index occur more frequently could be an issue for you. You should state whether it is as a part of your requirements.
* An attacker being able to associate words with a document could be an issue for you. You should state whether it is as a part of your requirements.
* An attacker may be able to subvert the server entirely and observe queries / retrievals. You should state security needs in this circumstance as well.
* Probably others I haven't thought of.
I'm assuming that you're designing your own, but there is probably some prior art, research, etc. that would be smarter than I am below:
For the first, I suggest that you should hash the words, combining the plaintext with a secret (not shared with the index server) before hashing, and truncating the hash to the point where it is likely to be non-unique in the index. This costs you hash efficiency, but helps prevent an attacker from using the hash as a plaintext equivalent or experimentally determining the secret
For the second and third, you should encrypt any indexed data (such as counts or document+position) and decrypt it on the client. This may cost you latency.
For the fourth, you'd want to consider concealing real requests inside groups of unrelated requests, things like that, but you'd want a lot of math to make sure you weren't still vulnerable to statistical analysis.
For the fifth, do some web research. I'm confident there will be stuff out there, and this is a pretty specific (and less common) need, so you'll want someone who put more thought into it than I just have. | Your requirements are mutually exclusive. That kind of metadata will leak a huge amount of information about the document content, to the point it can't be called secure.
Furthermore, encrypting individual words is futile. The difficulty of breaking encryption is usually said to be as difficult as breaking the key, but this assumes the information content in the plaintext is greater than that in the key. For single words, that certainly isn't true. |

Here, the adverb *away* is not mentioned at all, if had been added to the first clause, then the second clause would fit perfectly,e.g. “The second pigeon flew away just as the first one had done.”
There is the construction **do + so**, where different forms of ***do so*** substitutes the verb, and its complement. e.g. a) *The second pigeon **returned to its coop** just as the first one had **done so***. b) *They asked me to revise the essay and **I did so** (= I revised the essay.)* c) Dangerous currents.

To express concurrency of taking to flight (i.e. going from perch to flight) use similar constructs. The use of "also" further reinforces concurrency over similarity.

The words "just as" create some confusion in your sentence since "just as" as you used it is more likely to express concurrency over similarity. Additionally, there is an issue with "flew". I think you mean "took flight".
Your sentence as it's worded, however, tends to express similarity while using the concurrent form. |

75,263 | I read a recipe that said don't preheat the oven when baking a pound cake. Why wouldn't you preheat the oven? Every recipe I've ever read said preheat the oven. This is really confusing to me. | 2016/11/04 | [

] | I have seen (yeast) bread recipes that rely on an un-preheated oven and seem to take advantage of the slow heating process (give the leavener some time to act before incapacitating it by overheating). While pound cake is unlikely to use yeast, there was likely a similar idea on the recipe writers mind. Maybe getting a somewhat denser texture by firming the outer layer before activating the leavener in the core is the goal here. Such recipes tend to be unreliable because they make many assumptions about the bakeware and oven used.
EDIT: Another reason for somebody to develop a recipe that does not use preheating would be simply saving active time, especially for people having slow-to-preheat ovens - mix, put in cold oven, start oven, set a timer and step away. | Without seeing the recipe and likely experimenting, it is hard to know for sure, but a few thoughts on pre-heating:
The shorter a cooking time, typically the more important it is to preheat. If you are doing a 5 minute cookie bake, you are unlikely to get your desired results if you fail to pre-heat. If you are doing a 6 hour roast, well, you are probably just wasting energy preheating.
The general idea is, if your recipe calls for a temperature for 30 minutes, then it needs to be up to that temp and stable before you start. A counter argument is how can it be when you open the oven to put the item in and radically lower the temperature when you do that.
Part of the tradition of most recipes saying to pre-heat was wood stoves especially, but older models in general which heated slowly and one person's might take longer to come to temperature than someone else's. So, baking for 30 minutes in my stove that comes to temperature in 10 minutes would result in half cooked in someone else's over that took 20 minutes to come to temp, and burnt for someone else who pre-heated, so the pre-heat command put everyone on an even field. Today, most ovens heat up fairly quickly so it is less of an issue other than for shorter cooking times and things that need precision such as delicate pastries. BUT, and this is a big but, with many modern ovens which heat to temp quickly, they do so with higher power. So, if you put things, especially short cooking time items, rather than taking longer to cook, they will burn, but may also be half raw. While you have you oven set at say 350F, it may actually be pouring 500F heat at your dinner rolls until the full oven temp stabilizes, and you end up burning the surface while not getting the middle cooked.
Now, one reason I can think that a recipe might specifically say not to pre-heat would be to take advantage of this. That initial higher power while the oven is heating and stabilizing could help form a crisper crust and then allow the bulk of the cooking to occur at an effectively slightly lower temp, similar starting an item at a high temp and then allowing the temperature to fall as is sometimes done for a bread with a crisp shell like crust but delicate interior. The effect would be a lessor example of this. |

] | One obvious reason is to avoid wasting energy. A lot of people tend to like recipes which avoid preheating for this reason alone.
But, assuming that there's more than that here, my guess is that the recipe is trying to use the slower heating as a way to achieve a greater rise. Whether your pound cake recipe relies on leavening (such as baking powder/soda) or whether it's a traditional pound cake recipe that relies only on the air bubbles beaten into the batter while mixing, a gradual temperature rise can in some circumstances result in more expansion.
Basically, baking is a race against time in crust formation vs. internal expansion. You want to allow enough time for the internal gas bubbles to expand and make the cake (or bread or whatever) lighter, because once the structure starts to harden (with egg coagulation, and then starch gelatinization), you can't expand any more. On the other hand, as a cake or loaf rises, it becomes increasingly unstable. If you wait too long to form a crust and then stabilize the internal structure, your whole cake could collapse.
Frequently, the inside portion of a cake or loaf continues to expand even after the crust hardens, resulting in cracking on the top surface (common in pound cakes, perhaps even desirable according to some). In extreme cases with things like yeast breads, it can even result in a "blow-out" where the pressure from internal expansion literally blows a big hole in the crust.
With pound cakes, this balance can be a particular problem. As already mentioned, hardening the crust too early can result in excessive cracking. But hardening the crust later can also be a problem if the internal structure is unevenly heated (and thus unevenly stable). If the crust hardens while the cake is rising very high (e.g., from rapid expansion under high oven heat), but the internal structure is unstable underneath and collapses a bit, it can result in the "crust separation" where there's an air gap between the top crust and the rest of the cake. It's possible that heating more slowly can make that less likely by heating the whole batter more evenly and ensuring the internal parts of the cake are closer to setting along with the top crust.
Anyhow, to generalize a bit more, one of the reasons to slowly heat a baked good is to try to allow more time for a gradual expansion. On the other hand, internal air within batter/dough will eventually "leak out." It's actually a continuous process, since batter/dough is permeable to air. With cake batter, you can often actually see bubbles rising and popping on the surface of a cake early in the baking process. So you need *some* structure and crust to form to prevent all that air from escaping and collapsing your batter too. The trick, again, is to balance the time given for bubbles to form/expand vs. how fast the cake sets (i.e., structure hardens). That's actually one of the primary reasons for different baking temperatures in different leavened baked goods.
While allowing expansion during preheating can sometimes be helpful, it's also hard to manage. Ovens don't preheat at the same rate. If your oven preheats too slowly, it could actually cause your batter to rise too much before it stabilizes, thus resulting in collapse. As pointed out in another answer, some ovens with radiant heat elements (especially electric models) can actually introduce a "broiling" effect on the outer surface during preheating, which could counteract the positive effects if the "broiled" crust hardens early and prevents further expansion.
Since it's less predictable, most recipes tend to recommend preheating for things like cakes and pastry. And no matter what, you'll have to monitor doneness more frequently the first few times you do a recipe like this in a particular oven, since the time window for being "done" will likely vary much more significantly for recipes that don't preheat. | Without seeing the recipe and likely experimenting, it is hard to know for sure, but a few thoughts on pre-heating:
The shorter a cooking time, typically the more important it is to preheat. If you are doing a 5 minute cookie bake, you are unlikely to get your desired results if you fail to pre-heat. If you are doing a 6 hour roast, well, you are probably just wasting energy preheating.

] | Some people get upset if they find the same user posting the same question to multiple forum sites *at the same time.* It can be annoying if I spend ten minutes answering your question on site A, and then find your question, already answered, on site B. It's even more annoying if I see if on site C, as well!
But if a question isn't answered on site A after a reasonable period of time, it seems fine to ask it on another site. And you could make the case that since SE isn't actually a forum, but rather a repository of knowledge, slightly different rules apply.

20,822 | In the debt based fiat system of currency currently being monopolized, the amount of money added into circulation can cause it to deflate or inflate in value. How does the network calculate the proper rate at which to add more bitcoins? | 2014/01/20 | [

] | The answer for @jtorba is not strictly correct.
Difficulty is the main control mechanism used to determine the amount of Bitcoins released over time. The amount of bitcoins released is according to the bitcoin era as defined [here](https://en.bitcoin.it/wiki/Controlled_supply)
Currently the system tries to maintain a release of bitcoins every 10 minutes - which is part of the config settings that all miners adhere to. To do this the code takes into account the average block completion time every 2016 blocks.
It is important to note that this is NOT affected by the number of miners, but instead affected by the computing power.
A block is discovered by a process of hashing - which is a repetitive computing process - until a result is found that matches a rule. Obviously the FASTER you can repeat this process the better chance you have of finding the answer that fits the rule before anyone else. It is specifically designed not to matter how many computers you have doing this task.
The rule becomes increasingly difficult - hence the use of the word difficulty - and therefore more computing effort is required to cycle through the possibilities becomes harder.
This self adjusting process is the main mechanism that maintains the release of bitcoins to the schedule in the link above. | The simple answer is that it tries to keep bitcoin creation as steady as possible, but halving the rate every 4 years in order to sustain inflation in value.
The network makes mining difficult or easier by increasing/decreasing difficulty in order to achieve a 10 minute block time. If the amount of miners increases, that means a block will be solved less than 10 minutes and that becomes the que for the network to make it harder to mine. And if it on average took longer than 10 mins to mine a block, that the que to ease up mining. To put it simply, if the amount of miners doubled over night, it becomes twice as hard to mine bitcoins.
The network adjusts to the amount of people using the currency. |

] | To echo [Ben's answer](https://gaming.meta.stackexchange.com/a/4351/3389) somewhat, you sorta need to be a little more discerning when reading meta discussions. Meta should be inviting, but it's not the place to get quick rules of thumb or policies: that's what [the FAQ](https://gaming.stackexchange.com/faq) is for.
The ideal meta question—where the top answer exactly matches unassailable policy and should be treated like the word of god—doesn't exist. Every decision requires some interpretation and asking questions of more experienced users. Yes, meta is messy, but I think that's by design: this is where the sausage is made. Discussions are messy. Guidelines and policies made by humans are messy.
When trying to understand a meta discussion, sort order, scores, and accepted answers are less important than what the general arguments are. In most situations, however, the accepted answer is pretty close to the summary of consensus and the scores reflect what position should be (or has been) implemented.
Sometimes it's not, and many times there are good tells: the accepted answer has a bunch of negative comments, or is down voted, or is just inferior to the other arguments presented in other answers. Sometimes, however, it's not clear what the consensus is without reading everything and coming up with a determination for oneself.
But in trying to solve that edge case by removing accepted answers from being shown first because they might be contrary to what's been implemented, you introduce a new one: if something gets implemented long after the discussion happens (so by default it doesn't have as many votes), or if something gets implemented in a way that's unpopular, the canonical answer gets buried amongst all the noise of the surrounding discussion.
I'd rather keep the tool we have—and is used in good faith by most people to push the canonical or consensus answer to the top—rather than remove it in favor of sorting everything by votes. Stack Exchange isn't a popularity contest, and there's no reason why the messy discussions we have should be treated like one either. | I think they mean something on questions asked by moderators looking for consensus on a topic.

] | To echo [Ben's answer](https://gaming.meta.stackexchange.com/a/4351/3389) somewhat, you sorta need to be a little more discerning when reading meta discussions. Meta should be inviting, but it's not the place to get quick rules of thumb or policies: that's what [the FAQ](https://gaming.stackexchange.com/faq) is for.
The ideal meta question—where the top answer exactly matches unassailable policy and should be treated like the word of god—doesn't exist. Every decision requires some interpretation and asking questions of more experienced users. Yes, meta is messy, but I think that's by design: this is where the sausage is made. Discussions are messy. Guidelines and policies made by humans are messy.
When trying to understand a meta discussion, sort order, scores, and accepted answers are less important than what the general arguments are. In most situations, however, the accepted answer is pretty close to the summary of consensus and the scores reflect what position should be (or has been) implemented.
Sometimes it's not, and many times there are good tells: the accepted answer has a bunch of negative comments, or is down voted, or is just inferior to the other arguments presented in other answers. Sometimes, however, it's not clear what the consensus is without reading everything and coming up with a determination for oneself.
But in trying to solve that edge case by removing accepted answers from being shown first because they might be contrary to what's been implemented, you introduce a new one: if something gets implemented long after the discussion happens (so by default it doesn't have as many votes), or if something gets implemented in a way that's unpopular, the canonical answer gets buried amongst all the noise of the surrounding discussion.
I'd rather keep the tool we have—and is used in good faith by most people to push the canonical or consensus answer to the top—rather than remove it in favor of sorting everything by votes. Stack Exchange isn't a popularity contest, and there's no reason why the messy discussions we have should be treated like one either. | A part of Meta's system is Eating our own Dogfood even if it isn't 100% perfectly suited to unanswerable discussions. The Q/A format isn't perfect here but it's familiar and it works well when people play nice.
The top answer is obviously most important on the main site and casual users will just skim for the accepted/top answer, and we want that. But meta's not like that; if you're here, you're probably an advanced user who's enganged and willing/wanting to read the whole conversation.
I don't think Meta needs to be optimized for scanning like the main site's questions; we do that for correctness and anonymous visitors. Meta doesn't really get anonymous visitors and often we don't have "correctness" either. I don't think it's a problem worth messing with the system for. |

A conditional job offer is **not** a guaranteed one - there is no reason to consider it as one, most likely the other party (the company offering the job) is not.
However, once you have accepted an unconditional offer and have it signed and sealed, you should not be accepting any more offers and communicate cancellation to any outstanding conditional offers.
That said, background checks are considered very sensitive process, and unless it is actually related to the process, the identity of the person undergoing the check is not revealed to anyone in any matter. Only the results are shared with the organization requesting for the check.
And moreover, any conditional job offer that you have today is usually not part of a background check anyways, it's about the previous engagements, if at all. | >

There is always a risk depending on how extensive of a background check either of the companies have asked the background check company to perform. To prevent such incidents in the future, you should not simultaneously accept multiple job offers. You could potentially lose both offers if the companies are aware of what you have done. |
18,147 | Tempest devices could via intercepting from far away the electro-magnetic waves coming out from one's computer detect what one does on the computer. Employing the Faraday cage principle, one could prevent such detections. A. Stanoyevitch in his book Discrete Structures with Contemporary Applications, CRC Press, 2011, p.301 writes:
"Buildings can be fitted using a special insulation procedure that protects against tempest devices, but any company or individual in the US who has this insulation must first obtain a license from the federal Government."

] | The only applicable law for the US would seem to be FCC regulations against interfering with "any radio communications of any station licensed or authorized". [Marriott Hotels](https://apps.fcc.gov/edocs_public/attachmatch/DA-14-1444A1_Rcd.pdf) was fined substantially for blocking people's hotspots within the hotel. As I understand "tempest device", this is a method of obtaining information from stray EMR from computers and the like, which picks up on radiation emitted from a device. Stray radiation is not licensed communication. The problem would be if a room were insulated to block all EM radiation coming in or going out, including licensed transmissions. The main enforcement interest of FCC is with devices that actively jam signals (by transmitting interference). But the law, [47 USC 333](https://www.law.cornell.edu/uscode/text/47/333), states that "No person shall willfully or maliciously interfere with or cause interference to any radio communications of any station licensed or authorized by or under this chapter or operated by the United States Government". Insulating a room from incoming licensed radio signals is thus not allowed, under a "what the law says" reading of the law. However, laws are frequently interpreted in terms of beliefs about an intent, so it's possible that a court could eventually decide that the law was not intended to prevent construction of a Faraday cage room. The issue would then be whether an intentional action to do something allowed which has an (unintended) disallowed but non-harmful consequence would be deemed a violation (the user would be okay with blocking licensed transmissions into the room). I don't know of clearly applicable case law on that point. | A Faraday cage can prevent EM emissions that can (in theory) be used to eavesdrop on electronic devices. But no, there is no U.S. law against putting metallic screens around a room or within a building.

So even if you use only a little storage space and you make only a couple of requests, you have to pay the minimum RU per document collection. | You created 18 collections, meaning you have 18 billable database constructs. And with the lowest-cost collection starting at roughly 20 Euro per month (about 5 Euro per 100 RU per month, minimum 400 RU), the math works out: You basically created an environment with 400\*18=7200 RU. Perhaps just use fewer collections to reduce your cost footprint (note: collections have no rules around documents being homogeneous). You could use a single collection, since you have such a low amount of data.
**EDIT FEB 2018** - note: with database-level RUs (a feature added a few months after the OPs question was posted), the cost model would be very different. 18 collections would be able to share an 1800RU database-level allocation (the minimum is 400RU, up to 4 collections, then 100RU per additional collection). With database-level RU, the cost of an 18-collection configuration would start at 25% of the original cost, based on 400RU per collection. |

Maybe give them advantage on the Intelligence check if they describe you how they remember the way or let them use **Investigation checks to find their way back on track if they get lost.**
All in all, if there are no consequences for failed checks, I would like to refer to the **DMG (p.237)** which recommends that you assume, if they have got the time, they succeed automatically taking ten times the normal amount of time needed to get there. | What is the consequence of failure?
===================================
Let's assume that they fail. What happens now? I'm guessing that they will just use whatever method caused them to find it in the first place to find it in the second place. If so: **why are we wasting valuable playing time on this?**
Only if you decide that there *is* a consequence for failure should you bother making any type of check at all.

54,160,011 | Fairly new to capybara and cucumber (and testing in general) here.
I am doing some black box acceptance testing and I need to test a page that can only be reached by typing in the url.
That page requires authentication so when the page is reached through a call to visit() I am redirected to the login page.
The problem is after logging in the app does not redirect me back to that page but goes to the homepage instead so I can't just fill in the login form and move on.
I have tried logging in first and then performing a call to that page but it seems the session is cleared after any call to visit().
How can I keep the session after a call to visit, or solve this problem in any other way?
Ideally I would like to log in once and visit a bunch of pages only reachable by typing the uri, without having to log in again and again. Is that possible?
I am only using the chrome selenium driver but at some point will use a headless driver.

] | There might be a signing issue. Is your app signed? The default signing is the debug signing. When you just build and deploy or run it on a connected device, it is signed by default as a debug sign.
If it is **not** uniquely signed, then running or installing on other devices might not be possible. Look at the app signing instruction and guide by Google, [here](https://developer.android.com/studio/publish/app-signing), if you wish to distribute your app on other devices.
Another problem might be in the security authorization of other devices. Your device on which you are building has the developer options turned on. To run and install unsigned apps you'll need to activate the developer options in the device you want to run it on. Look at this [link](https://developer.android.com/studio/debug/dev-options) about Developer Options and how to turn it on. | by default the Android Studio packages just the needed files and installs the app in your mobile. If you share to other mobiles, the app will not install in few devices due to a few reasons like OS version, files mismatch, SHA keys mismatch, etc.
However, if you build the APK and share, the APK is equipped to be installed in any device starting from the minimum SDK version to the target SDK version. |

130,691 | This is a question from a study guide for a military officer exam:
I have fluid flowing through an elbow in a pipe (the elbow is in the shape of an upside down and backwards "J") and the flow goes from south to north to east. If holes are drilled at the upper left outside part of the bend and the lower right inside part of the bend, at which point will pressure be lower? Please see attached image for a picture of the question.
When I have thought about this problem, I keep coming back to pressure being transmitted equally to all parts of a fluid, so I don't understand how the pressure can be different at one of the holes. The book gives the answer as the inside bend which I can force myself to accept since I can picture the fluid attempting to go straight to the outside bend hole and thus hitting that part harder, but I don't really understand it. | 2014/08/12 | [

] | When a pipe is bent the outside curve - what would be the longest path through the curve - has the highest pressure and the lowest speed. The inside curve - the shortest path through the curve - has the lowest pressure and the highest speed. In short, when the path of a fluid in steady-state flow bends, the pressure on the outside of the bend is always higher than the pressure on the inside of the bend.
The pressure would be lower on the lower right inside point of the bend.

] | If you imagine the bend portion of the pipe to be a part of a circle, it becomes apparent that there is centripetal force present. As the water travels through the bend, there is a centripetal force that acts inwards towards the centre of the "circle". There must be a reactionary force to this which acts in the opposite direction, in other words the outer wall of the pipe.

] | If the home is maintaining the temperature set on the thermostat (at least AT the thermostat) then it's probable that you are near, but not quite at, "design load" for the furnace. At design load, the furnace runs 100% of the time to keep up with heat loss in the house and maintain temperature - if it gets colder than that outside (below the "design temperature"), the house gets colder than set. At anything less than design load, the furnace runs a fraction of the time, and is off a fraction of the time. The closer the outside temperature is to "design temperature" the longer the run time and shorter the off time. As it gets warmer outside, the off time increases and the run time gets shorter.
Anything that makes the house lose heat faster raises the effective design temperature (doesn't change what temperature was assumed to design it, but alters the actual one.)
Anything that makes the house lose heat slower lowers the effective design temperature (doesn't change what temperature was assumed to design it, but alters the actual one.)
If the house is NOT maintaining the set temperature AND the furnace is shutting off regularly, something may be in need of maintenance/adjustment. | As Ecnerwal said, your furnace cannot keep up with heating your home. This could be caused by a number of things.
1. Your furnace itself is inadequate and cannot keep up with the load. The rating in BTUs is not high enough.
2. There are inefficiencies in your home which is causing the furnace to work harder than it was designed to.
* The furnace requires service.
* Insulation in your home may be inadequate.
* There could be air leaks and drafts caused by old windows, doors, etc.
* Too many leaks in the duct work are causing heat loss.
3. You are trying to maintain a temperature that is too high for the furnace to handle.
There are a number of services available that will come into your home and do an energy audit. They will be able to figure out what issues you have in your home. They will do tests like the blower door test to determine how many air leaks you have. They also have special tools such as thermal cameras that can see where the heat loss is. They will also inspect your insulation to see if it meets code. I would also recommend that you have a technician come in and service your heating equipment. |

1,116,283 | I need SFTP functionality on my Windows 2012 VPS server.
According to [this page](https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui), one of the prerequisites is that I'm running at least Windows Server 2019 or Windows 10 (build 1809).
My hosting company says they can migrate everything to Windows Server 2022, but there will be costs and my sites will obviously be down for a little while.
1. Does anyone know if a SFTP server can be installed on Windows Server 2012?
2. Does anyone have experience doing this? Any recommendations?
3. Would this be greatly simplified if I used plain ol' FTP? I don't think our data is particularly sensitive. | 2022/11/21 | [

In the Windows ACL model, neither has higher precedence than the other – instead the **sum** of all matching "Allow" permissions is used. So if you grant X to Authenticated Users but Y+Z to Domain Admins, the user is effectively granted X+Y+Z.
However, *Deny* entries have higher precedence than any "Allow" entry. (Again, the sum of all matching "Deny" entries will be denied.)

240,556 | After a hard drive died on a RAID5 setup on a legacy system, the Vmware Virtual Machine on it kept on running for a period of 6 months. Needless to say, finally it crashed bad. Now, the dead hard drive has been replaced and RAID5 restoration tools have been used to recover the lost data.
Yet, the logical drive is still giving IO errors. Is this normal? Should we be worried about further data loss?

] | You aren't telling us enough:
Are you using a hardware RAID controller? Which one? If not, software RAID on what operating system? Did the recovery have finished without reporting any errors? Did the RAID management tools for the RAID solution you are using report the volume as working fine? What kind of I/O errors do you get? Are they reported by the host OS or the guest machine?
Also, I can't help but to remark that you should have started to worry six months ago when the drive died. If a drive fails in a RAID setup you have to replace it immediately, especially with a RAID5. Any error on one of the remaining disks will fail the recovery, so there is no time to loose. | Yep, you should for sure but that's not 100 % warranty, you know.

8,317 | I have noticed that interior of the ISS appears to be very disorganized.
Let me clarify what I mean by that. I grew up watching Star Trek, and the Enterprise was *the* reference of clean space-faring vehicle. Things were in drawers, hidden. Or structured in a clean way. Computers were built into larger panels. There were touch screens. Have you noticed they always needed to uncover a panel to access some occasionally accessed system? It was minimalistic design.
When I look at the ISS, everything is everywhere, and it seems like nothing is attached firmly to the main frame. Things are just loosely attached to the wall and there are so many cables, devices, objects, ... that one wonders
* how do they not cut themselves all day with some sharp edge
* how do they not break or make a cable loose
* how come those objects, machines, devices did not break already by bumping into each other a long time ago
given there is no stabilizing force in a form of gravity.

] | In Star Trek there is artificial gravity, and lots of staff. On the ISS there is neither. The crew spends a lot of time maintaining the station. They barely get time for science operations, with all the time they spend on maintenance. Going to a crew of 7, which Commercial Crew vehicles will enable (bringing 4 at a time, acting as a lifeboat for 4, instead of Soyuz with only capacity for 3), is expected to greatly increase available time for science. Just by adding one more body, on top of all the time the current staff of 6, will more than double available science time.
There is not a lot of storage space in the station, all things considered, and when cargo comes up on a vehicle, it comes in bulk, all at once. They track where everything is, else it gets lost in the scrum. The Dragon and Cygnus vehicles are mostly volume limited, but the ATV and HTV bring up a fairly larger amount all at once. It all has to go somewhere, and you need to keep track of where everything is.
There was a [great video of Sunnita Williams](https://www.youtube.com/watch?v=doN4t5NKW-k) hunting for something. She looked up the location on the computer, went to the specified location, opened a cabinet, and pulled out three layers deep of boxes. The item she wanted was in the box at the back.
Thus there is a great deal of order, hiding behind the seeming disorder. Looks can be deceiving.
The inner storage areas of the station are really well organized. The visible surfaces definitely look like a hodge-podge, but they are taking advantage of available surface area to store things they use a lot. | At 4,000 to 14,000 dollar per kg in launch costs, pretty panels are a huge waste of money. It needs to be fixed solidly enough to withstand a crewmember bumping into it, and easily detachable enough to be replaced when needed.

] | The short answer - it depends. If it's a fairly complex or sizable application, I like to create a service layer project with the repositories as dependencies. If it's a small application, I'll put the logic in the controller. In my opinion, if it takes more time and effort to create the service layer than it would be to create the application (i.e. one or two controllers), then it doesn't make sense to me to go that route. You also need to consider the likelihood that the application will grow.

Your application structure could look like this (each in different projects):
* Data storage layer (e.g. SQL database)
* ORM (e.g. NHibernate or Entity Framework)
* Domain (including abstract repositories and entities)
* Service layer (and optionally business)
* MVC application (which has it's own models relating to the entities)
but there are many ways to go about this depending on the complexity and size of your application. |

What is the reason for this? Is it because of legal reasons and / or security reasons? I imagine account sharing would not be a problem if there weren't some real-world consequences for the *company*, not just the end-user. | 2017/09/13 | [

] | It's important to have a firm grasp of precisely who the legal entities are in any contractual agreement, so you know who you have to sue or blame or whatever if it ever comes to that.
Less seriously, if account-sharing were permissible, then blaming "somebody else who was using the account at the time" would be a reasonable response to any punishments for violating any other rules. By prohibiting sharing that way, a company eliminates the hassle of having to deal with that argument (which is usually impossible to disprove) in response to bans. Obviously people still try to use that defense, but a company can simply point to the rule against account sharing and say "well that's not allowed either." It makes life way simpler for the GM team.
It also has a small side-benefit: it means that if you and your friend want to play, you have to buy two copies of the game, you can't buy one and share it. This is obviously also better for the company. | From both a legal & security standpoint, the single biggest factor I'm aware of is accountability. If you cannot determine who is responsible for the account, you cannot reasonably hold anyone accountable for actions related to the account. For instance, money laundering is easier if you cannot trace account ownership. Forbidding shared accounts won't prevent laundering in all forms, but it is choosing to not make it easier & demonstrates an effort on the part of the developer to not facilitate such things.
You didn't ask specifically about this aspect, but I feel it's equally important - there are also design implications to shared accounts. For instance, as a designer, you might not want players to pay others to accomplish objectives due to the impact it has on the game experience. You might not be able to full prevent such things, but you can take steps to discourage them & forbidding it via the terms of use may be part of such a solution. |

] | In addition to all the other answers, there is another reason: **Ensuring leaderboard integrity by prohibiting account sharing and multi-account usage.** A famous example is the rhythm game [osu!](https://osu.ppy.sh), which states as its **first** rule:
[](https://osu.ppy.sh/wiki/Rules)
Due to the game's ranking system ("[performance points](https://osu.ppy.sh/wiki/Performance_Points)") absence of this rule would destroy the leaderboards, as a top player could easily dominate their rank range by just repeating their top scores. | I run Wildfire, a multiplayer network backend for Crysis Wars.
Like other networks, we don't allow account sharing- our ToS never actually goes into detail as to why this is, but I made this decision because:
* One copy of the game per account- allowing users to share their accounts would *dramatically* skew the statistics of that account. For commercial networks, this would simply mean that they miss out on the revenue from multiple accounts purchasing a unique licence for the product.
* Accountability- if a user of the account violates the ToS, it has an impact for all users using the said user account. Separate accounts mean that only one person is banned/suspended/warned, affecting just that one person when compared to multiple people. In addition to this, allowing multiple people to use a single account would make it *very* difficult to pin the blame on a single person.
* Leaderboards- multiple people using one account would *seriously* inflate the statistics of the account (similar to my first point). By this, I mean that for Crysis Wars (an FPS) the amount of kills/deaths/points attributed to an account will be abnormally higher, and this is unfair for legitimate users.
* Security- multiplayer backend systems, like my own, log *everything* (and I mean everything). There are several security systems that I use that these logs support- one of them is that the system automatically locks-out a user if it detects that it is using multiple IP addresses at the same time. Similar systems do the same. |
