But this sentence does not work: One would understand it (outside the context of this discussion, at least) as "power flows from responsibility" which is the opposite of what is meant.
This is true for all such constructs: "Scorching heat comes with high pressure areas": The heat brings high pressure? Hm, *maybe.* I'm no meteorologist. "Unpleasant administrative work comes with lots of money" sounds outright funny: who ever got rich from administrative work!?
The word order in all these cases is essential: It must reflect the flow of causation. If we change it, like in the examples, the causal relationship is changed with it.
The actually interesting question may then be why the relation is not expressed the natural way: "Great Power comes with great responsibility." Unambiguous, straight-forward. Great power is there first, and it is inevitably accompanied by responsibility. But by having power be the subject, this sentence is perhaps too power-centric, while we actually would like to emphasize the responsibility. So we make responsibility the subject, the center of attention and not the sidekick. But then we lose the logical flow, so we have to invert the normal word order.
As a rhetorical side effect, the unusual word order creates a little stumble and may renew the attention of a sleepy audience; it is even pretty catchy, isn't it? |

] | As the other answers have pointed out, the normal word order would be, “Great responsibility comes with great power.” Inverting the word order doesn’t change the meaning, but makes the sentence sound more formal. It’s especially typical of old-fashioned poetry, which often needed to rearrange a sentence to fit a particular rhyme scheme and meter. This homily is also familiar enough that native speakers are likely to recognize it.
Leaving aside forerunners that were translated from other languages, such as Luke 12:48, we have [numerous versions of it in modern English,](https://en.wikipedia.org/wiki/With_great_power_comes_great_responsibility) whose word order varies considerably. I’ll add emphasis to the subject of each sentence.
William Lamb, 1817: “**the possession** of great power necessarily implies great responsibility.”
Winston Churchill, 1906: “Where there is great power **there** is great responsibility, where there is less power there is less responsibility, and where there is no power there can, I think, be no responsibility.” (“Where there is ...” is a dependent clause, and this is a compound sentence.)
Theodore Roosevelt, 1908: “**responsibility** should go with power.”
Franklin D. Roosevelt, 1945: “**power** must be linked with responsibility, and obliged to defend and justify itself within the framework of the general good.”
“Superman Comes to Earth,” 1948: “Because of these great powers—your speed and strength, your x-ray vision and super-sensitive hearing—**you** have a great responsibility.”
The version you give, though, is most associated with Stan Lee and Steve Ditko’s *Spider-Man*. His first story in 1962 ends with a slightly-longer version:
[](https://i.stack.imgur.com/zrBrt.jpg)
The 2002 film *Spider-Man* had Uncle Ben say, “Remember, with great power comes great responsibility,” in his last conversation with Peter Parker before he died. (Very similar to how Superman heard the same lesson from his father-figure before the latter died, fourteen years before Spider-Man was created.) This became the best-known version.
You can also see the adage getting shorter and pithier over time. The version that caught on is, explicitly, an abridgment of Stan Lee’s “... aware at last that in this world, *with great power* there must also *come*—*great responsibility.*” This itself is similar to the word order of Winston Churchill’s quote. “Where there is great power, there is great responsibility, ....” but shorter and simpler: Churchill said it as a compound sentence whose parts all have subordinate clauses. | "Great responsibility" is the subject, and the normal word order, as mentioned in the other answers, would be "great responsibility comes with great power".
But this sentence does not work: One would understand it (outside the context of this discussion, at least) as "power flows from responsibility" which is the opposite of what is meant.
This is true for all such constructs: "Scorching heat comes with high pressure areas": The heat brings high pressure? Hm, *maybe.* I'm no meteorologist. "Unpleasant administrative work comes with lots of money" sounds outright funny: who ever got rich from administrative work!?

69,953 | Something strange happened in my bathroom. For a few days the tub spout was leaking non-stop. During that time the water pressure had been low and there was no hot water. I thought that the leak was coincidentally due to a bad valve seat or washer.
However, once the water temp and pressure issues were fixed, the leak went away.
Anyone have any ideas how something like this can happen? | 2015/07/28 | [

] | Its evidently a pressure balanced valve. Most single handle valves are today. | Spouts will not hold pressure. They will stop water. So if you have extra water in the pipe from valve to spout, the spout stopper will hold it (some don't even do that) but it will only hold pressure to a point (and some hold really no pressure).
So if your valve was pushing water to the spout due to some other reason then your spout would leak. It could just be a tiny amount of water leaking out your valve. This would go down to spout - gravity - your spout would intermittently leak as pressure builds past its limits. |

Sort of. Apache Karaf can use Apache Felix. Apache Karaf can also use Equinox or another OSGi runtime. By default, the Apache Karaf standard download does come with Apache Felix.
>

Again, sort of. The standard download of Apache Karaf does come with Apache Aries by default.
Now let's talk about what OSGI (Apache Felix, Equinox) is and what Apache Karaf is:
OSGI is very simple. You can start an OSGI runtime in your application and not even notice it. The shell, the ability to hot deploy from a folder, install from a maven repo, etc..These are all extras that OSGI doesn't have to do and are provided by additional projects like Karaf, GOGO, or Pax
Now on to Apache Karaf:
It is basically an OSGI environment that provides some additional goodies on top of a standard OSGI implementation. Because Apache Karaf is just built on standard OSGI, it can in theory run on any OSGI runtime. This gives you a uniform interface for working with OSGI runtimes.
Some goodies Apache Karaf provides that you won't see in a Apache Felix without some additional work:
* Folder based hot deployment
* A (IMHO) better default console than gogo. (org.apache.karaf.shell)
* Remote SSH access to that console. (org.apache.karaf.shell.ssh)
* Centralized Logging System. (org.apache.karaf.log)
* It has it's own way of provisioning bundles and start levels. (org.apache.karaf.features)
* Karaf has it's own maven plugins as well.
Pretty much anything here:
<http://mvnrepository.com/search.html?query=org.apache.karaf>\*
I mentioned Karaf having it's own way of provisioning bundles and start levels. Apache Karaf also comes with a bunch of pre-defined ones to get started with. I know Apache Felix comes with some as well, through OBR, but Apache Karaf comes much more 'batteries-included'. | Apache Karaf is a swiss army knife to run OSGi "stuff" and non OSGi things bundled as OSGi.
Felix and Aries are default but the frameworks are pluggable, so equinox works as well.
* "Unix like" shell accessible from CLI or SSH
* Hotdeploy of bundles
* May deploy almost anything as a bundle (plain .jar, spring xml, blueprint, etc)
* WAR files
* Deploy from maven - including autowrapping non OSGi bundles.
* Web Console
* Karaf features - ".kar files" that includes bundles and custom karaf features/commands.
A side note is that Karaf is part of ServiceMix (the initial name was ServiceMix kernel), so it has very tight integration with Apache Camel, Apache CXF and Apache ActiveMQ. Turning Karaf into an ESB with those features is trivial. |

For example, the `qsort` function works with a user-provided comparison function. There are numerous subroutines for solving ordinary differential equations, or for optimizing functions, and they all take function pointers as arguments.
In windowing systems, all kinds of callbacks follow the same pattern.
In Lisp, even in the early days, there was something called a "functional argument" or FUNARG, which was not only a function, but it also contained a storage context where it could remember and interact with part of the outside world.
This same need exists in OOP languages, except when you pass the address of a function you also have to pass the address of the object the function is a method of. That's two things you have to pass. So a delegate is just that, and allows that good old pattern to still be used. | My first encounter with delegates was checking for a program update (windows forms C# 3.5) by downloading a file from my website, but to avoid the update checking locking the whole program I used a delegate and a thread to do it asynchronously. |

How far you have completed the Civil War Quests will affect some conversation choices. But even after you have negotiated a truce, the war will continue. Some achievements could be affected if you take over a hold tied to one.
Remember, you will have to finish the entire Main Quest before continuing with the Civil War after finishing Season Unending | If you finish either side of the civil war questline before the Main Queast, "Season Unending" will not occur at all, as the war is ended and no truce is needed.
but if you started "Season Unending" then finished the civil war before completing "Season Unending" The best advice I can give you to check back with Jarl Vignar Greymane to see if he's verdict has changed, or Go to Esbern as instructed and see if it clears up. |

[This](https://screenrant.com/im-thinking-ending-things-biggest-unanswered-questions-explained/) article speaks about the question in length. Here is a section from it that talks about Jake's struggle:

> he needs to answer the question the young woman has debated for the
> entirety of the film, and that is whether or not they are going to end

> the frail state he is currently in, and Kaufman furthers that by
> making his fantasy begin to fall apart around him. As the story
> progresses, the more confusing it gets; the characters change, and
> Jake gets increasingly closer to ending things. The calls are coming
> from inside of Jake’s head and interrupting the projection of his
> desires because he cannot escape who he is and what he is actually

] | First the assumption that databases have one primary write server is incorrect. A lot of set ups have multi- master configs and clusters. There are also distributed database systems where data is written to different servers based on various conditions.
Though not required, database can still be containerized, especially when dealing with microservices. Each microservice can have its own database and it all depends on how your infrastructure has been architected.
Here is a small excerpt for a good read. I am [linking the article](https://containerjournal.com/topics/container-management/11-things-to-know-about-databases-and-postgres-in-containers/) as it's too big to copy paste here
>
> A containerized database is an encapsulation of its DBMS server software, with access to a physical database file residing somewhere within the network. Each DBMS is encased in its own container image. Containerizing a database, however, is not quite as straightforward as containerizing an application.

> | Personally, I really like the idea of putting a golden set of data in a VM or container for QA testing. Spin up a new VM/container for each project and you can test it in isolation. When testing is complete, it goes away cleanly. You can do the same thing for development: Think git branches.
I can't tell you how many times I've had projects look like they were failing because someone mucked up the data in the dev/qa environment to test a different project. |

538,794 | My problem: I am trying to power a project with a 8x32px flexible matrix, 8x8px flexible matrix, 24px ring, 16px ring and 7px jewel (two of each), totalling up to a **whopping 734 pixels**. For my project I only am using a maximum of **408** though.
Each *lit* LED at 100% luminosity is either drawing 60mA (white), around 40mA (mixed) or 20mA (primary color). My color is in the mixed area (hot pink) so I used 40mA for my calculations, which already has a little overhead (since no primary color will be at 100% usage).
The amps needed here would be: 408px \* 40mA / 1000 = **16.32A**
Each *unlit* LED draws ~1mA, so: 1mA \* (734px - 408px) = **326mA**
Totalling up to **16.646A**.
Now, I could decouple the two 8x32px matrices from this, which would total to **12.88A for them alone** and making the other circuit a breeze to power, but those two 8x32 matrices (edit: not the two circuits, sorry for the confusion) need to be in sync, so they need to run off of one microcontroller and preferably one power supply (I don't want three power supplies spread out in my costume, no thanks).
Any suggestions on how I could accomplish this? I have looked through dozens of sites and even thought of using an RC car LiPo battery, but I don't know if that's overkill or even fits in my costume. Any help in this is greatly appreciated and if there are questions requesting more info, I am trying my best to supply it. | 2020/12/23 | [

] | This started as a comment but got a bit long;
Neopixels / Ws2812s need a 5V **regulated** supply and do indeed draw 50-60mA per unit when at full brightness.
This is enough to see significant voltage drop down a long string or tape (guess how I know) so the LEDs at the far end of a strip light up red because there's insufficient voltage for the green & blue LEDs to strike up. So, you need a robust power feed to your various "groups" of LEDs - and remember voltage drop gets worse the lower your power supply voltage. 12A down a long wire or PCB track is a significant amount of power.
I would either use one large-ish RC Lipo battery and a few DC-DC (buck) converters near each "group" of LEDs (EG you feed 14V or 18V from the LIPO to a small DC-DC that powers one LED matrix - that way any drop in the wires doesn't affect the metrix) or I'd source a few USB power banks and attach those to the various groups if that's workable - USB power banks do the voltage regulation and easy recharging for you, at the cost of bulk & expense.
Synchronising with your micro is a bit of a challenge if you distribute power supplies, but commoning the grounds solves one side and since the LED control is omni-directional (transmit only), you could maybe use opto-isolators at the LED end to drive the LED data decoupled from the microcontroller voltage. There may be other ways - there's plenty of optical and digital isolation ICs and little modules/boards out there from China that would likely solve your problem.
You can see voltage drop over cable length/size here to give you some indications;
<http://fuddymuckers.co.uk/tools/cablecalc.html>
12A at 5V gives **1V drop per metre** on 1mmsq cable - if you source that same 60w of power from an 18V battery and only regulate it down at to 5V at the last minute you only lose 0.28V/metre in that 1mmsq cable. | WS2812 or similar is very bright. Do some test before choosing numbers. I powered 300 pieces, each chip got summary 5 of 256x3 and got enough light in enlightened room. Consumption is 0.5A and voltage drop in 5 meter string is 350mA. Run power to each piece of your assembly separate wires from PS. Whan power disconnected, chips loosing data. Best way to turn off and keep it synchronized write "0" but keep data in controller memory. One chip will consume less then 1mA. Controller is rewriting data to LEDs with some time intervals. |

It is rather a design philosophy than somewhat concrete. In general, it means that you should preserve the semantics of the content, think of your content as of a piece of structured information. And that also means that you should keep all aesthetic details away from this structured information.

Surely. Better structured information generally remains readable even if certain browsers render styles incorrectly (or do not render them at all). Such content may also look more adequate on printed media (though print styles may be applied to achieve even better aestherics -- they, again, have nothing to do with content semantics).

Of course. The separation of content and presentation takes its roots from more general philosophy, the separation of concerns. Everybody benefit from the separation: the content supplier does not have to be a good designer and vice versa. |
77,414 | From what I know in a closed system the potential energy + the kinetic energy is constant since no external work is done on the system. In my textbook it says that enthalpy is equal to the sum of the KE + PE meaning total energy. My question is how can the energy be lost to the environment after the collision of two particles. Since as the particle approach each other KE is turned into PE until activated complex is reached. Once it is reached they break up into smaller particles, repel each other and convert the PE back to KE. In conclusion all energy in the system is constant and no energy is lost. I don't quite understand why we have Enthalpy vs Time graphs. Since the energy in the system was never changed it simply converted between forms. For my homework when I pretended that enthalpy was simply PE and that endothermic = increase in PE and exothermic = decrease in PE I usually got it corrected(Such as question below). Is it not true that if you decrease PE by a amount KE would increase by that amount hence no change?
For instance a question from my homework "After a reaction, the product have less KE than original reactant molecules. Is the reaction endothermic or exothermic?"
Im thinking to myself that if KE has decreased PE must increase hence no change in energy so neither endothermic or exothermic. But the answer is endothermic.
In conclusion my main question is can I ignore the definition the textbook gave me and define enthalpy as total PE and delta enthalpy = change in PE rather than total energy. | 2017/07/07 | [

] | In any way, ignoring the definitions given in a textbook is a bad idea. As for the question, the main problem in your thoughts is that you mixed too many things from different fields of science. Your example (two particles, kinetic energy, potential energy etc) looks like classical mechanics. So if you want to explain it, please, use tools offered by classical mechanics. Enthalpy is a measure of total energy in thermodynamics. It is used to explain processes taking place in large systems, which can be characterized with volume, pressure, temperature etc. It is not used to describe one particle.
Maybe you can take it into account and revise your question. Make it clear exactly what you want to understand: change in the kinetic and potential energy in interactions of two particles or change in enthalpy in exothermic and endothermic reactions. | No. H = U + pV, where H is the enthalpy of the system and U is its internal energy. And the internal energy is the sum of the internal potential energy and the internal kinetic energy.
Thus:
enthalpy = internal PE + internal KE + pV
N.B.: The term "internal" refers to energy internal to the system. For example, the internal kinetic energy is the energy the system has as a consequence of the thermal motion of its atoms and molecules, as contrasted with the external kinetic energy the system might have as a result of the motion of the system as a whole through space. |

-----------------------
Before the Space Shuttle ever flew, a lot of testing had to be done. Among the test items were the OV-101 (Enterprise), STA-099 (later OV-099, Challenger) and the Pathfinder (later OV-098, no STA designation known). The latter was partly built of wood.
OV-101 Enterprise
-----------------
[](https://i.stack.imgur.com/0Em0G.jpg)
The Enterprise was built without engines or functional heat shield. Also a lot of other systems were missing. It was intended as a flight test article first, but was planned to be upgraded to full orbiter status after conclusion of testing, becoming the second orbiter after OV-102 Columbia. Design changes during the construction of Columbia forced NASA to reconsider this. After the Challenger disaster, refitting Enterprise was again brought up but ultimately decided against.
STA-099 Challenger
------------------
[](https://i.stack.imgur.com/zwIfQ.jpg)
Like the Enterprise, Challenger was first built for testing. It was a full airframe with a mockup crew module and partial heat shielding. It was put to the test for 11 months. After that it was fitted with a functional crew module, parts were reworked and was launched on orbital missions as OV-099.
OV-098 Pathfinder

1,716,382 | The SVN book describes deltification as "each time a new version of a file is committed to the repository, Subversion encodes the previous version (actually, several previous versions) as a delta against the new version."
This [collab.net blog article](http://blogs.open.collab.net/svn/2007/03/how_subversion_.html)
says that "In BDB (Berkeley Database) fulltexts are found at the tips of each distinct line of a file's history." while "FSFS stores deltas in the opposite direction so that old versions never need to be rewritten."
If this is true, will SVN (using BDB) store a full copy of a file at the HEAD of each branch and then eliminate one copy of the file if the branches are merged? | 2009/11/11 | [

] | SVN only stores deltas - that is, what has changed between commits/versions. This is one reason you can't just go back and delete an old version, since newer revs depend on what has come before. In addition to saving disk space, this lets you quickly see what's changed between versions.
This should also apply when merging from a different branch. New files are added, changed files are merged - deltas stored - etc. | No, because the older revision still exists. In other words, in order to go back to the previous non-merged version it has to keep it around. |

Practice a koan physically, verbally and mentally. For example, walk with it, speak it and feel it.
This sounds mysterious, but is actually practical. To walk with a koan, one might attend to "left foot original face", followed by "right foot original face". When meditating, one could silently speak the koan. To feel it one could look at anything that appears as "this tree original original face feels tall", "this car original face feels fast". And so forth. In other words, tie the koan into everything seamlessly.
In this way one discovers "original face" and can answer the Roshi by presenting the original face. It takes much practice because most of us are distracted by other stuff day-to-day and moment-by-moment.

Choose ONE koan. Not two. Of the two you refer to, I recommend 'original face', unless you are spending a LOT of time with your teacher, as the second one will become a philosophical fiasco otherwise.
Don't rationalise. It's not a philosophical or intellectual exercise.
Ask yourself the question when you are not thinking about it.
Lots of Zen practitioners write it down. Paint it. Draw it, etc.
Does it help? Maybe. Maybe not.
Don't talk about it. It's your practice. Don't talk about your practice except to your teacher. Maybe your students, one day.
Importantly, it's not a question about rebirth. You don't need to believe in rebirth in order to realise this koan.
Also, and paraphrasing @OyaMist's answer, also, there's nothing special about you either. So when you perceive anything, you can ask yourself in that moment: "what was its original face before it was born?", whereas for @OyaMist, it's often "does it have the buddha nature?"
The main, core, essential process? Just sit.
It's going to kill you. That's the point. But don't lose your life. If you are on the correct path, the path itself is an enriching and empowering experience. Hard work sometimes, painful sometimes.

We enter samadhi to brighten our minds and temporarily rid ourselves of our coarser defilements. When we shift these obstacles to the side, we are better able to work with our original minds and directly see what the koan is pointing at. Our smaller mind is simply unequipped to perceive what the bigger mind is capable of investigating. It works with logic and language. The big mind we access through samadhi, on the other hand, works with the unintelligible fragments of our store house consciousness that koans seek to address. Put another way, trying to answer a koan without samadhi is like trying to hear a symphony with your nose. Your nose is great if you want to smell a flower, but it is useless for the purposes of listening. Koan study requires that we direct the proper, purified sense to the case we are given.
Before you embark on koan study, it is absolutely essential that you learn to purify your mind and body. Work with your breath. Master doing nothing. Mingle your eyebrows with those of the patriarchs and pass the barrier where the foaming billows wash the sky. Until you do, koans will remain inaccessible. |

Two things to look:
1. That shutter speed can change so that you can define how smooth motion you want
2. That they offer fast zoom/focus capabilities for sports.
Any recent cam-corder from major companies already covers this.
If you want quality sound you should also look for a camcorder that has an external mic jack so that you can connect your own microphone. This raises the budget a lot.

* Split the string into individual messages
* Separate general messages and all other messages
* Order expected and actual messages in the same order (e.g. alphabetical)
* Compare ordered lists of expected and actual messages. Now that they are ordered the same, they should equal item-by-item
* Check that the general messages come after all other messages in the actual message stream. | You'd better compare `Set`s of messages, as the fuzzy string comparison you're after is going to be too tricky... |

] | If one really wanted to, one could find a way to use the heat generated by [Darvaza gas crater](https://en.wikipedia.org/wiki/Darvaza_gas_crater) in Turkemenistan. Adapting the method used to construct the replacement [sarcophagus at Chernobyl](https://en.wikipedia.org/wiki/Chernobyl_Nuclear_Power_Plant_sarcophagus) that was rolled into place in 2016 something could have been constructed a safe distance from the fire crater & then rolled over make use of the heat.
There are two problems with this however. The first is how much power could be generated from a "roll over the crater power station" given that it is not an ideal way to make a power plant. The second problem is the fire crater is locate in a wilderness region remote from people who could use the energy that might be generated. Power transmission lines would need to be constructed which would add to the cost and if the amount of power that could be generated was modest at best the cost may not justify doing anything. | If it was profitable; the way to handle this situation is to drill from a safe distance to the source of the gas and flood with cement to stop the gas flow. Then drill conventional gas wells to produce the gas for use. A variation of the control of gas/oil wells in Kuwait that were sabotaged by Saddam Husain. Not being a petroleum engineer , I am speculation at the use of cement . An evaluation of real information would be necessary to pick a good solution. The Wiki article indicates it is a failed gas well drilled by Russia, if so, drilling to an appropriate point in the original well casing to inject cement would be very feasible. Being a well , that also means the gas may be coming from a reservoir miles below the surface. |

374,135 | I'm on IIS 7 and .NET 4.0. My understanding is that IIS takes requests and passes them off to ASP.NET worker threads. If all the threads are in use, the request goes into a queue and is processed once a thread becomes available. If the queue goes over a certain size, all new requests get a 503 until there is room in the queue again.
Is there a way to prioritize the order in which queued requests are served? For example, I have consumer traffic and infrastructure traffic coming to the same server. If there are no available threads, I'd like for the consumer requests to be served first, even if they have arrived after infrastructure requests. Basically I want to replace the request queue with a priority queue. Is this possible with IIS? | 2012/03/27 | [

] | There are a bunch of queues that might be involved; I think your description is incomplete.
IIS allows you to specify that particular parts of a site run in different Application Pools, each of which runs in a separate worker process.
Each App Pool has a kernel-mode request queue (defaults to 1000 requests) used to ensure that in the case of a recycled W3WP (worker process) that requests don't get lost, but this also becomes the practical maximum limit for outstanding requests at a given moment.
If this queue fills up, you get a 503.
App frameworks - like .Net or classic ASP - may also implement their own user-mode request queue which runs within the worker process. I don't believe it's possible to prioritize different requests within the framework (unless there's an ASP.Net feature that does this that I'm not familiar with).
If you have a limited number of threads in each process' thread pool, separating apps into (for example) static content and active content app pools can help keep basic work off the thread pool of a busy app process. (Likewise, adding more threads is (arguably) a reasonable approach to this). | I don't believe so, but you could have two sites, one for consumer traffic and one for infrastructure traffic, then they'd each have their own queues. |

=====================================================================
While you cannot just redesignate a ranged attack as a melee attack, there is no general rule preventing you from using those attacks at close range, i.e. melee range.
Disadvantage at close range can be negated
==========================================
Generally, close-range use of ranged attacks imposes disadvantage. This can be negated using the crossbow expert feat which *does* work for non-crossbows, see this question: [Crossbow Expert Feat... for Spells?](https://rpg.stackexchange.com/questions/117386/crossbow-expert-feat-for-spells)
Removing the restriction without the feat is a problem
======================================================
Taking a feat is an investment. Giving the same benefits out for free is a problem since it changes combat balance and devalues the feat. You could talk to your GM, however, and ask if this benefit can be taken instead of some race or class feature. Discussing this in detail would be beyond the scope of this answer. Restricting the benefit to just *firebolt* would be a pretty minor feature, however. | Sort of, but with disadvantage
------------------------------
Attacks are designated as melee or ranged, and you’re unable to choose to make a ranged attack into a melee one. You can make a ranged attack at point blank range, but you’re still governed by the general rules of ranged attacks, as found in Chapter 9 of the PHB and Basic Rules under “**Ranged Attacks in Close Combat**” (emphasis mine):
>
> Aiming a ranged attack is more difficult when a foe is next to you. *When you make a ranged attack with a weapon, a spell, or some other means, you have disadvantage on the attack roll if you are within 5 feet of a hostile creature who can see you and who isn't incapacitated.*

So you can make that *fire bolt* attack close up, but it’s still a ranged attack, and so will be made at disadvantage. |

There's no general rule which lets you make turn a ranged attack into a melee attack. On the contrary, trying to use a ranged attack in melee will give disadvantage (PHB 195).
Since you are wanting this for a character concept, you don't need a rule for turning ranged attacks into melee attacks, you need a cantrip which fits what you want for the concept.
Unfortunatly, there are no cantrips which directly fit your bill, so you should work with your DM to figure something out. Fortunately, the design pattern of cantrips is fairly tight so it should be easy to cobble something together.
Specifically, you could have the cantrip — let's call it *flare* — be a mod of *firebolt* except with a melee spell attack. As most squishy sorcerers would like to *not* be in melee range, this doesn't generally make it stronger than *firebolt*. Another approach is to use start with the Druid cantrip [*primal savagery*](https://www.dndbeyond.com/spells/primal-savagery) (XGtE) and change the acid damage to fire damage (and change the descriptive text to be less about teeth and fingernails.

In blitz (and partially in bullet games), you have fewer time, but your **opponent** as well. Depending on the level of your adversary (and your own level of course) it is harder to keep everything defendend as solid as you would do in a classic/rapid game.
And as we know:
>
> "When loose pieces are on the board, tactics arrive."

But in rapid games both players have more time to think through and therefore the defenses are -normally- better organized. Loose pieces won't show up as easily, unless you force your opponent. You should therefore invest more in positional and long-term thinking (*make up a plan!*).
Blitz and bullet focus more on short-term 'quick wins'. Rapid leans more towards classical play. Therefore play it more like a classical game, but don't overthink all the moves since the time is limited. Invest in a good opening repertoire and train how you can win the typical end games that follow the openings you tend to play.
Also, a tip (I often see this with my chess students): don't confusing winning a rapid play in 5 minutes with a real rapid game on eg. 20 min. If you win the game in that timing, you just played a blitz game with rapid timings.
**So in short:** look for tactics, but if you can't find them: continue with your long-term plan.
PS: Don't forget that most regular/club level players play 90% of their games in the same tempo (ie. bullet, blitz, rapid, classic or correspondence). Every type has it's own dynamics and required playing style. So just play a lot of rapid games and you'll improve by yourself. | I can sooo relay to that - I tend to play Blitz too...even in a tournament game. (The upshot is that it acts as a bit of psycho terror on the opponent :-) Since it is a character trait, it is very hard to countervene that, and even worse, in 99% of all cases I'd play the same move anyway after pondering longer. It is the 1% where you overlooked a tactics of the opponent that cost you dearly, and my only advice might be that before you play the move, just for a second pretend to be your opponent...what would the other side play?
P.S. I don't think it is counterintuitive that you see tactics faster in a blitz game, since there you concentrate your brain power on tactics. You'd have to be very strong and/or very experienced to automatically play positionally good moves. |

As I improved I started to realize that wasn't strictly true, I just degraded less than my opponents, so my results were better; it didn't mean my playing strength was higher.
There is certainly something about the pressure of having to come up with a move *now* that focuses the mind, though, that maybe you can harness. Next time you're in a longer game, pretend you're blitzing and look for the move. Don't act on it, just look for it. When your "Blitz Brain" comes up with its move, take a little more time to really analyze it. See if it's actually good. Does it stand up to a deeper scrutiny? If so, only then play it. IOW, treat your "Blitz Brain" as a candidate move generator. |

Blitz and bullet focus more on short-term 'quick wins'. Rapid leans more towards classical play. Therefore play it more like a classical game, but don't overthink all the moves since the time is limited. Invest in a good opening repertoire and train how you can win the typical end games that follow the openings you tend to play.
Also, a tip (I often see this with my chess students): don't confusing winning a rapid play in 5 minutes with a real rapid game on eg. 20 min. If you win the game in that timing, you just played a blitz game with rapid timings.
**So in short:** look for tactics, but if you can't find them: continue with your long-term plan.
PS: Don't forget that most regular/club level players play 90% of their games in the same tempo (ie. bullet, blitz, rapid, classic or correspondence). Every type has it's own dynamics and required playing style. So just play a lot of rapid games and you'll improve by yourself. | Heh, when I was young I was better at blitz than "normal" chess, as well. As I improved I started to realize that wasn't strictly true, I just degraded less than my opponents, so my results were better; it didn't mean my playing strength was higher.
There is certainly something about the pressure of having to come up with a move *now* that focuses the mind, though, that maybe you can harness. Next time you're in a longer game, pretend you're blitzing and look for the move. Don't act on it, just look for it. When your "Blitz Brain" comes up with its move, take a little more time to really analyze it. See if it's actually good. Does it stand up to a deeper scrutiny? If so, only then play it. IOW, treat your "Blitz Brain" as a candidate move generator. |
14,129 | I live in the Sierra Nevadas, a little over 8,000 feet up. There's an area in my yard that has rocks with a bright shiny sheen to them. I've seen some kind of coating on nearby plants (which doesn't seem to harm them), which I'm guessing is maybe the same thing.
Some facts:
* It's a ~30 square foot area.
* Rain, shine, cold, hot: it always looks the same.
* It's not wet to the touch and doesn't rub off easily.
* If I flip a rock over (shown), the part in the dirt doesn't have the sheen.
* It doesn't really make the rocks very slippery; not anymore than normal.

93,272 | The spell [Liquefy](http://www.d20pfsrd.com/magic/all-spells/l/liquefy) states that:
>
> Items with hit point damage or the broken condition regain 5 hit points/caster level
>
>
>
It also states earlier:
>
> If the item has magical or alchemical properties, they become inert for the duration of the spell.
>
>
>
I inferred from these two lines that the spell can be used to repair hit point damage on a magical item. However, the [Broken](http://www.d20pfsrd.com/gamemastering/conditions#TOC-Broken) condition says:
>
> If the item is magical, it can only be repaired with a mending or make whole spell cast by a character with a caster level equal to or higher than the item's.
>
>
>
These two pages do not completely agree with each other: one specifies a caster level requirement (and lists two specific spells) while the other does not. This leads me to three possible conclusions:
* *Liquefy* is more specific than the *Broken* condition, and it ignores the caster level requirement imposed on *Mending* and *Make Whole*
* *Liquefy* obeys the same caster level requirement as the two other spells
* *Liquefy* cannot be used to repair broken magic items, because it is not listed in the *Broken* description
I think the third option is unlikely to be the answer, but it is still a possibility so I included it. | 2017/01/17 | [

] | *Liquefy* is more specific than *broken*, and explicitly states that it works on magical items. Further, *Liquefy* explicitly states that it "has no effect on artifacts, constructs, or intelligent magic items", which gives further credence to it working to repair magic items.
Since it doesn't mention a caster level, *Liquefy* would ignore *Broken*'s normal caster level requirements (which already only apply to *Mending* and *Make Whole*).
So, anyone capable of casting *Liquefy*, or using a magic item which replicates its effects (eg., a scroll), can use it to repair any non-intelligent, non-artifact, non-construct magic item. | No, *Liquefy* cannot repair **Broken** Magic Items.
Liquefy can allow:
>
> Items with hit point damage or the broken condition [to] regain 5 hit points/caster level if drained into a bottle in this way.
>
>
>
But, the Broken condition states that Magic Items can only be fixed by a
>
> *mending* or *make whole* spell cast by a character with a caster level
> equal to or higher than the item's.
>
>
>
This seems to imply that Liquefy can have several results:
A non-magical item, reduced to any number of hit points more than 0: Liquefy restores 5 HP/caster level
A magic item, reduced to more than half its hitpoints: Liquefy restores 5 HP/caster level
A magic item, reduced to less than half its hitpoints: Liquefy has no effect, as it cannot fix a broken magic item. |

As far as I know, including Had + past participle is a must when forming past perfect tense.

] | I think the verb 'get' in the sentences presented implies to receive.
In AE, the past participle of get is 'gotten", whereas in BE, it's "got"
So if you follow AE, you should use gotten. On the other hand, if you follow BE, you should use got.
Besides, you say you don't have or haven't got in BE when you talk about possessions, relationships, etc., whereas in AE, you usually say you don't have. If you want to convey this sense, you can rephrase the sentence as follows:
She was very sad because she hadn't got/didn't have the package (BE).
She was very sad because she didn't have the package (AE & BE). | This first sentence is ambiguous in British English, because "have got" can mean possessing something. Here are some ways of rephrasing it:
>
> She was very sad because she didn't receive the package.
>
> She was very sad because she didn't get the package.
>
>
>
...meaning the package didn't arrive, or:

] | If you haven't climbed in a while I would recommend staying away from doing fingertip pull-ups on hang boards. My assumption is that you are out of climbing shape and tendons and ligaments are easy to injure and take a long time to heal. This is coming from someone who has been climbing for around 8 years off and on and has made many mistakes, please learn from mine. Over all, take it slow when returning from a hiatus.
Available products I have used without injury are the powerball and the grippers. Both are small and can be used when you might otherwise be wasting time, like waiting in line at a store.
For further advise I would suggest reading [Training For Climbing](http://trainingforclimbing.com/). It is edited by a well known, longtime (34 years) climber on the east coast, Eric Hörst. He is also frequently featured (74 times!) in a podcast called Pod Climber, giving training advice. I found this valuable as I could listen in the car. | This is a common question for beginners to ask. Climbing feels overwhelmingly strenuous when you're starting out. There are a variety of exercises that are recommended to strengthen your fingers, I can enumerate them below, but some are given in other answers. But I want to emphasize the following:
**If you have access to a climbing gym, or live somewhere with outdoor rocks accessible after work, you will get significantly better gains in your climbing ability from just climbing 2 or more times a week, consistently, that you will from pure finger-strength training. Especially if you're a beginner.**
If you've been climbing for a while and are looking to supplement your training, or if you just can't climb all that frequently you could consider the following:
Using general fitness equipment:
* Finger curls with a barbell: <http://www.nicros.com/training/articles/eastern-bloc-training-heavy-finger-rolls/>
* Deadhangs from a pullup bar. Try to keep your arms slightly bent, and hang for as long as you can. Try to build up to 4 minutes. Be careful, this can be hard on your shoulders. I personally can't do this exercise because of shoulder problems, but have friends that can.
Specialized pieces of climbing equipment:
* Metolius Rock Rings: <http://www.metoliusclimbing.com/rock_rings.html>
* a hangboard: <http://www.backcountry.com/store/search.html?mv_session_id=UmsK5WiA&q=hangboard>
With either of these you would want to do dead-hangs (like on the pullup bar), and focus on the larger holds for the first few months. **I don't know what your fitness background is, but both of these can should be considered "high risk" devices. They're designed by and for experienced rock climbers. They're targeted at people who are already climbing 5.12 sport climbs or V5 boulder problems. If you're not at a similar level of fitness, you could easily injure youself using them. Climbers regularly put their hands into positions that can only be considered orthopedic-ally unsafe when they grip tiny holds.** |

* Squeezing plasticene or stress balls
* Dumb-bell curls
* Chin-ups, both on a bar, and finger chin-ups on a door frame or similar
* Press-ups on fingertips
These give finger, hand, wrist and forearm strength - worthwhile using them together. The thing I'm not so good at is toughening up the backs of my fingers. I play guitar, so my fingertips are nicely callused, but I always scuff the backs of my fingers when trying to jam into cracks. | Climbing is the best exercise for finger and hand strength improvement, just make sure to warm up and stretch.
EDIT:
Just want to defend my answer. There are a lot of books out there you can read about climbing for training. Many of them will tell you not to waste your time cross training. The best training for climbing, is climbing.
Now if you are advanced there are other methods, but the useful ones are directly related to climbing.
The most obvious are fingerboards. Do dead hangs and pull ups in all different finger positions and different common climbing holds.
The next is H.I.T., or "Hypergravity Isolation Training", where using HIT boards you can follow a regimen to work solely on hand strength while still in a climbing format. You can train pinches crimps, and varying pocket sizes with different finger combinations.
There are also campus boards which are wooden boards with varying degrees of crimping difficulty which are ridiculously difficult and strenuous and should only be used by top tier climbers or you will injure yourself.
Now, with all these methods in mind, just climbing a wall will do wonders to improve your hand strength, whether it be top-roping, lead, or bouldering (or other).
So don't worry about cross training, just go climb a wall. When you really hit a plateau (Probably around the 5.10 going into 5.11 level or later), look into HIT. |
