] | I can see at least 6 possible interpretations, but there are probably more:
1: The speaker is not allowed to tell the listener, but someone I else can. (**I** can't tell you...)
1a: The speaker isn't allowed to tell the listener, with no inference as to whether anyone else can.
2: The speaker is not allowed to tell the listener, but can tell someone else (I can't tell **you**...)
2b: The speaker is not allowed to tell the listener, with no inference as to whether the speaker can tell anyone else.
3: The speaker is not physically capable of explaining (I **can't** tell you...). This option does not make sense because if the speaker is capable of communicating their inability to explain, they should be able to explain how they felt.
4: The speaker is physically capable of explaining but cannot formulate the right words.
5: The speaker's emotions cannot be expressed in words, but only though other means (I can't **tell** you...)
6: The speaker is not sure how excited they were to meet the listener's brother and therefore can't tell the listener. (I can't tell you **how excited**...)
You can identify other interpretations by stressing different words in the sentence. Eg:
X: The speaker can tell the listener how excited they were to meeting everyone except the listener's brother (I can't tell... your **brother**) | The first and most reasonable interpretation would be "There are no words to describe my excitement of meeting your brother!", "I enjoyed meeting your brother so much I can't find the right words to tell you about it!"
One might think that the speaker really cannot tell how much they enjoyed the meeting, but this interpretation sounds wrong to me. Why can't they tell? Is it a secret?
So, the first is correct. By the way, Demis Roussos has a song called "Can't say how much I love you" and it goes like this:
>
> I can't say how much I love you
>
>
> Say how much I need you
>
>
> I could never find the words to say
>
>
> I really really want you and you are all my eyes can see

It's not that he really can't say how much he loves her. He can but there are no words to describe his love accurately. So, it's just a hyperbole, an exaggerated statement not meant to be taken literally. |

The adjectives "little green" simply augment the expression and give it a rhythmic ring. | This sounds like a mash-up of two different phrases, ***little green apples*** and ["***have kittens***"](https://idioms.thefreedictionary.com/have+kittens).
The first appears in various expressions; the most familiar may be ["sure as God made little green apples"](http://www.dictionary.com/browse/sure-as-god-made-little-green-apples), which means that something is very certain (Dictionary.com), but also [*for the love of little green apples*](https://www.google.com/search?q=%22for%20the%20love%20of%20little%20green%20apples%22&rlz=1C1CHBF_enUS696US697&oq=%22for%20the%20love%20of%20little%20green%20apples%22&aqs=chrome..69i57j0.5216j0j4&sourceid=chrome&ie=UTF-8) (apparently substituting the thing God surely made for God's name) and [***shit little green apples***](https://www.google.com/search?safe=active&rlz=1C1CHBF_enUS696US697&ei=NhLJWtCyEJnljwS3pb3QAw&q=%22shit%20little%20green%20apples%22&oq=%22shit%20little%20green%20apples%22&gs_l=psy-ab.3...9042.9902.0.10133.6.6.0.0.0.0.100.490.5j1.6.0....0...1c.1.64.psy-ab..0.0.0....0.dfOX9FRfQOs). That last is very similar in meaning to "have kittens" which, as [@Laurel's answer](https://english.stackexchange.com/a/440500/177853) mentions, is a phrase similar to "have a fit" meaning something like "become upset" or "be very angry" (The Free Dictionary).
Combining the two phrases in this way may be a way of evoking the cruder "little apples" phrase, or it could just be a way of making the "kittens" expression more colorful (pretty much literally). It is also possibly intended to emphasize how certain it is that the kittens will be had, playing on the "certainty" meaning of the longer "little green" expression. Since the combined phrase isn't common, the exact meaning should be gleaned from context.
A bit of evidence for the combination of these phrases:

It's probably not a coincidence that all these examples are from various discussion fora, where conversational participants come from all over the world and pick up and play with idioms from folks well outside their physical neighborhood. This would help explain how the relatively US-centric "little green apples" gets combined with the relatively British "have kittens". |

41,162,099 | I have a problem understanding the principle handling of oauth 2.0 tokens.
My scenario is, I have a web based frontend backend system with node.js and angular 2.
A user should be able upload a video on this site. Then some additional metadata is created (dosen't matter for this question). When that is done, the user could upload the video to youtube with the additional data by clicking on a button.

Here is the tutorial I used:
<https://ionicabizau.net/blog/14-uploading-videos-to-youtube-using-nodejs>

] | I am not sure what you mean by 'Token'.
In order to access any Google API you will first need to register your application on [Google Developer console](https://console.developers.google.com). You will then need to create Oauth2 credentials. Oauth2 credentials is were your application will request access from a user to access the data on their YouTube account.
On Google Developer console you will need to save the Client id, client secret and the redirect uri. All three will be needed by your code to authenticate the user.
When the user grants your application access to their YouTube data. You will get an access token and a refresh token back from the authentication server. Access tokens are short lived about an hour and are used to make requests (like upload) to the API. A refresh token can be used to request a new access token once the one you have currently has expired.
You will probably end up with the following:
client id, client secrete, redirect uri, and a refresh token.
If you are interested I have a tutorial that is part of my Google Development for beginners tutorial series that explains [Oauth2](http://www.daimto.com/google-developer-console-oauth2/) and how it works. | An access token is generated from the Server side and sent back to client from where the access request is generated. For all the subsequent requests you need to pass the access token which will be verified with the signature of the token saved on the server to check the authentication of valid requests. You will only get 1 access token which will be used.
You can also use "Refresh" tokens in case you need to keep your access tokens valid for longer duration. |

] | La Jolla California, is an example; unless you know the 'J' is soft like an 'H', many would pronounce it with the hard J. If you don't speak French, or are not Catholic and know Pius 1X is a pope, you might not pronounce Pius IX as something like Pea Neuf in Montreal. I doubt there's anyway to get how something is pronounced unless a native tells you.
I was skiing at Mont Tremblant when an American fellow asked me how to find the Grand Pricks. The Grand Prix is a pretty famous auto race, but he did not know that! | You cannot learn names 'naturally', but you can learn them if you put effort into remembering them, such as repeating them over and over in your head. Even native speakers do this, not because they find them hard to say, but because they are naturally forgetful!
Because of this, they will be understanding about any issues you have with names, so don't worry about asking for help. It's one of the best ways to improve on any aspect of a language. I would recommend explaining that you are not a native speaker, and find names particularly difficult. You could even ask people to say their names slowly, and perhaps repeat them a couple of times.
Again: don't be afraid that this will annoy people. In fact, they'll be touched that you're making an effort. Not many people appreciate how much people like it when you take an interest in their names. Names are the primary way that people identify themselves, and anything that shows you're trying to get them right, is worth doing. This also applies to street names: it's important to people because it's where they live.
If you have have any close native English friends, you could always ask them instead when you see them later. If not, you'll probably acquire more friends there anyway, over time.
Eventually, as you practise name pronunciation more and more, it will get easier, just like the grammar and vocabulary did. |

If you don't speak French, or are not Catholic and know Pius 1X is a pope, you might not pronounce Pius IX as something like Pea Neuf in Montreal. I doubt there's anyway to get how something is pronounced unless a native tells you.
I was skiing at Mont Tremblant when an American fellow asked me how to find the Grand Pricks. The Grand Prix is a pretty famous auto race, but he did not know that! | We native speakers don't always get these names right, either! (You'll see this below.)
Aside from the very salient answers already given, I'm inclined to suggest that you choose one geographical area. Of course the English language is used natively in a diverse set of nations across the globe, so I'm afraid you'll drive yourself crazy trying to learn so many diverse people's names or place names at once!
For example, you might live or might like to live in London, in British Columbia, in Southeast Texas, in Lagos, or in Western Australia; or you might have contact with people from one of those places. So you could focus on the names from those places, only learning the others as needed.
For example, major US cities' names come from the following origins:
* **English place names**: New York, Boston, Birmingham
* **French place names**: New Orleans
* **Greek**: Philadelphia
* **Spanish**: Los Angeles, San Francisco, El Paso (less prominent: Las Cruces, Boca Raton)
* **Native languages**: Chicago (a wild onion), Seattle (from a chief's name)
* **Egyptian place name**: Memphis
* **Contemporary people's names**: Nashville, Raleigh, Washington, Pittsburgh, Houston, Dallas, Denver
* **Saints' names**: Saint Louis, Saint Paul
* **Geographical features**: Little Rock, Salt Lake City
* **Latin**: Cincinnati
* **Hybrid native/Greek**: Minneapolis
Also note that New York City, formerly Nieuw Amsterdam, has ***many*** Dutch (Netherlands) place names, adapted to English inconsistently. For example the name of the Van Wyck Expressway [is somewhat controversial](http://www.nytimes.com/2011/05/26/nyregion/van-wyck-expressway-also-snarls-pronunciation.html).
Any other large English-speaking country might have its own mix. And the problem is, each of those source languages is going to have its own phonology. Sometimes we get it wrong--before I recently traveled to Abuja, I was pronouncing the name of Nigeria's capital with the accent on the wrong syllable. And I'm still not sure if one form of Lagos or the other is favored!
So I strongly suggest you focus on the part of the English-speaking world most of interest to you and learn the rest only as needed. |
2,667 | What was the name/author of a Sci-Fi book where the Sun goes Nova and Earth and Venus must fly away? It was written like a memoir from a scientist from the future who accidentally was thrown into the past by a lab experiment.

] | There is a very good reason you can't find the book's original English version - not only was it originally written in French, but it was also (quite sadly) NEVER translated into English :(
The book you are referring to is "**Fleeing Earth**" by French scientist and sci-fi author **Francis Carsac** (that's his pen name, his real name is [François Bordes](http://en.wikipedia.org/wiki/Fran%C3%A7ois_Bordes)); French book name is "Terre en fuite", published in 1960.
Carsac's books were very popular in USSR (here's "Fleeing Earth"'s [Russian Wikipedia entry](http://ru.wikipedia.org/wiki/%D0%91%D0%B5%D0%B3%D1%81%D1%82%D0%B2%D0%BE_%D0%97%D0%B5%D0%BC%D0%BB%D0%B8)), but for some reason that completely escapes me were never translated into English, at least according to Wikipedia.
**A short synopsis:** As you noted, the book is written as memoirs written by a scientist/leader from the FAR future, that happened after several ice ages and a long period of Earth being conquered by aliens. The scientist accidentrally sent his conciousness back in time duiring a failed experiment where it inhabited the body of the person who wrote the memoirs.
In the lifetime of that scientist, he discovered that Sun is about to go supernova in several years. Humans manage to construct great engines that are mounted on both Earth and Venus (which at that time is colonized by ~1bn humans); which are able to drive the two planets out of Solar system. The planets then travel to neighbouring stars, encountering a couple of civilizations, some alien and some descendants of early humanity's lost starships. | Although you've already accepted an answer, I found another story which matches what you describe - although it's all nine Solar System planets, not just Earth and Venus, that must fly away - so I'm posting it here in case it helps others searching for similar stories.
**"Thundering Worlds" by Edmond Hamilton** ([which you can read in full online](http://fantasticworlds-jordan179.blogspot.co.uk/2013/06/thundering-worlds-1934-by-edmo.html)) is a short sci-fi story which describes representatives of the nine planets of the Solar System coming together to work out what to do when their Sun dies, and proposing to transport their whole planets across the galaxy:
>
> "Our sun is dying. Our nine worlds' peoples are menaced by awful and increasing cold, and unless something is done soon their inhabitants will perish. We can not hope to revive our dying sun. Its doom is already close at hand. But out in space there lie other suns, other stars, many of them young and hot with life. If our nine worlds revolved around one of those hotter, younger suns, we could look forward to new ages of life for our race.
>
>
> "It has been proposed, therefore, that we cause our nine worlds to leave our dying sun and voyage across space to one of those other suns! That our nine planets be torn loose from our sun and steered out into space like nine great ships in quest of a new sun among the countless suns of the universe! That we carry out a colossal migration of worlds through the vast interstellar spaces!
>
>
> "This stupendous plan to voyage out from our sun into space on our nine worlds has a sound scientific basis. Our worlds can be propelled in space under their own power just as our space-ships are. Our ships, as you know, are moved through the void by atom-blasts that fire backward and thus by their reaction hurl the ship forward. It is possible to apply this principle on a vast scale to our planets, to fit our worlds with colossal atom-blasts which will fire backward with unthinkable power and push our worlds forward in space!
>
>
>
One of the memorable details of the story is also the political machinations between the planetary representatives:
>
> Standing with Hurg of Venus at the window, I pointed up at a number of dark, long shapes sinking out of the gray sky. "There come our fellow Council-members," I said.
>
>
> Hurg nodded. "Yes, Lonnat—that first ship looks like that of Tolarg of Pluto, and the next two are those of Murdat of Uranus and Zintnor of Mars."
>
>
> "And the last one is that of Runnal of Earth," I added. "Well, the solar system's peoples will soon know how we of the Council decide on the plan, whether it's accepted or rejected."
>
>
> "Most of them are praying it will be accepted," Hurg said. "If it were not for Wald of Jupiter and your enemy, Tolarg of Pluto, I would be sure it would be accepted, but as it is—"

If that's not possible and there are already orders in the new database, I don't see a good option to import the data. | If he's concerned only with looking at revenue for business analytics, it doesn't sound logical to merge the old and new Magento stores together just for this simple task. Why don't you just set up a "locked down" version of his old site so he can export data from there and compare with the new site?
Magento tools for such a purpose are not very robust and he can be better served using data exported from the old site and imported into more powerful analytics software. |
72,310 | I recently switched my SRAM 1x12 Eagle SX drivetrain from a 30 to 34 direct mount Chainring. I also bought a new chain to accompany with it. Chain length was measured as the sram service manual advices. Put the chain around the largest rings and have 4 links overlapping.
The cassette has around 700km.The previous chain had around 0.5% procent wear.

In the case where an unofficial rule1 cites an official rule2 which is then superseded by another unofficial rule3 then if you are going to use the first unofficial rule1 then you need to consider as a table what the implications are of changing to the second unofficial rule3 and make your decision.
---
1 - Unearthed Arcana "Kits of Old", Fighter Archetype: Scout incorporates the Ranger class feature Natural Explorer.
2 - Ranger class feature *as published in the PHB*.
3 - Ranger class feature *as published in Unearthed Arcana "Revised Ranger"*. | Putting aside the fact that both the Scout archetype from UA Kits of Old and the UA Revised Ranger are not "legal" classes in the normal sense, you cannot swap one class' features with another class' features, even if they have the same names, unless your DM has allowed it.
The Scout archetype was clearly written using the PHB Ranger's Natural Explorer feature in mind, given that it was written before the Ranger, Revised article:
>
> **Natural Explorer**
>
> At 3rd level, you gain the ranger class feature of the same name, with the following alteration: You choose additional favored terrain types at 7th and 15th level.
>
>
>
In addition, the UA Revised Ranger's Natural Explorer feature does not include a Favored Terrain option at all, and based on the description of the feature on the Scout archetype it seems clear the Scout is focused on the survival and terrain exploration features of the PHB ranger, not the martial aspects of that class.
If your DM (or you, if you're the DM) has decided that some or all of the Unearthed Arcana character options are allowed, you still cannot swap the Scout archetype's Natural Explorer feature with the Revised Ranger's Natural Explorer feature, because class features for each class are unique to that class and only that class, and the Scout was written with balance against the PHB's ranger in mind.
The UA Revised Ranger is a new class. It does not update the Ranger in the PHB, nor does it update any other class. The features defined in the UA Ranger article only apply to the UA Ranger. You could play either the original PHB Ranger or the new UA Ranger, but not swap features between them--at that point you're making a new, custom class.
The same could be said about using the UA Ranger's Natural Explorer feature with the UA Scout archetype; you're no longer using the Scout as written (because it was intended to use the PHB ranger's Natural Explorer Feature) but instead are making some custom homebrew class, which could upset the balance of the Scout archetype in comparison to the PHB Ranger or even other PHB Fighter archetypes.
That being said, [as Dale has pointed out in his answer](https://rpg.stackexchange.com/a/91789/9399), you're already well beyond official rules territory here, so it really is up to you and your DM and the rest of your group how you intend to proceed. |

] | Much more important than the location of the 0.1uF capacitor is the equivalent series resistance (ESR) of all decoupling capacitors as well as the equivalent series inductance (ESL).
That being said, caps such as low ESR low ESL ceramic, Alum and plastic Film caps these days have improved a lot over decades ago. When the distance is too far you are essentially adding ESL and ESR to the capacitor and also radiating the ground loop near other circuits and thus injecting ground spikes.
The self-resonant frequency and impedance vs F determines the amount of ripple reduction at RF and smaller parts have better characteristics. So large e-caps handle up 1~10MHz and small ceramics above that up to their self-resonant frequency (SRF).
* So, low ESR is 1st priority (not all 0.1uF are the same)
* Close proximity is 2nd priority.
* Both are essential for ripple reduction at load without resonance. | 1. You can connect the capacitor wherever you want as long as it is according to the schematic, BUT best practice is to connect it as close to the IC as possible to assure the best decoupling of high frecquency noise components.

For more information about bypass capacitors, there's a [good article at Seattle Robotics](http://www.seattlerobotics.org/encoder/jun97/basics.html). | Much more important than the location of the 0.1uF capacitor is the equivalent series resistance (ESR) of all decoupling capacitors as well as the equivalent series inductance (ESL).
That being said, caps such as low ESR low ESL ceramic, Alum and plastic Film caps these days have improved a lot over decades ago. When the distance is too far you are essentially adding ESL and ESR to the capacitor and also radiating the ground loop near other circuits and thus injecting ground spikes.
The self-resonant frequency and impedance vs F determines the amount of ripple reduction at RF and smaller parts have better characteristics. So large e-caps handle up 1~10MHz and small ceramics above that up to their self-resonant frequency (SRF).
* So, low ESR is 1st priority (not all 0.1uF are the same)
* Close proximity is 2nd priority.
* Both are essential for ripple reduction at load without resonance. |

113,461 | I have created two projects, one with a Tiny RTC and another one with the BM180 sensor to read barometric pressure and temperature. Now I want to combine both.
I'm trying to connect both - the BM180 sensor and a TinyRTC clock module via. the I2C pins to my Arduino Uno (r3) and because I'm just a beginner I have some problems.
The BM180 works with 3.3V, but the TinyRTC is on 5V. Can I just connect all the SDA together and all the SCL together? | 2014/06/07 | [

] | The DS1307 used in the TinyRTC is not designed to run at 3.3V. It will go into backup mode, only keeping time. But it has a Voltage Input High minimum of 2V. As I2C is a open collector bus, where a device only pulls the line low, and then releases it so the pull-up resistors bring it high, this can be done simply by making sure the pull-ups are connected to the right voltage. Since the BM180 can only run at 3.3V, that sets the required i2c voltage.
Power the TinyRTC at 5V, and the BM180 at 3.3V. Simply remove or cut the i2c pull-ups on the TinyRTC module. If your BM180 is a module with pull-ups to 3.3V, then you are done. If not, use two pull-up resistors (4.7k is average) to a 3.3V source. Then the rest depends on your code. | Here is an interesting article (technical paper) to read, which describes how to do it using only a MOSFET for each I2C line, and some resistors.

] | You have a bit of an XY problem. The problem is not how to safely transfer files to your sandbox. The problem is how to not accidentally transfer the files to a non-sandbox. This is minorly complicated by the fact that your sandbox is virtual, so you will have to transfer the files into a non-sandboxed piece of hardware in a way that only presents risk to the sandboxed part.
A CD-R is an incredibly safe way to marshal data from one machine to another. Being a very old and very simple API, it is highly unlikely that your host will manage to mismanage the hardware in a way which exposes your physical machine (though always possible... that's the price one pays for playing with fire). Contrast this with USB, which is a relatively complicated protocol. I doubt my USB thumb-drive has enough exploitable firmware to turn it into some malicious unerasable attack vector, but I can't be certain. CDROMs are pretty darn simple -- much easier to trust. (Remember, one of Stuxnet's attack vectors was a USB exploit)
And its very easy to see how to not propagate the virus anywhere: don't stick the CDROM in any machine you don't want infected. When you're done, you have a host of sanization procedures available to you. My personal favorite is 10 seconds in a microwave.
Remember, when you're playing with malware, you're always playing with trust. You start with some level of trust that your computers will do the things you think they are doing. As you introduce malware, its not that the computer gains viruses, its that you lose trust. You can no longer trust that they do what they claim to do. Tools like sanitization procedures are designed to leverage what you do trust to restore trust to other areas. For example, snapshots rely on your trust of the host OS in order to restore trust in the client OS you are using as a sandbox. | Use a virtual machine that can control a USB device, and that *takes away control by the host machine*, i.e. the host machine no longer sees the USB when it is inserted.
Then transfer the files by cheap USB stick and physically destroy it afterwards
(Or store it safely for future investigation)
Sorry, I do not know which VMs offer this (does VMware do this?). |

Don't process malicious files in a VM running on a host of any value.
=====================================================================
While transferring the files is probably not your biggest concern (moving bits from one location to another is not inherently dangerous) the processing that happens during or after the transfer can be dangerous to the guest *and* the host.
It may be possible to attack the host from the guest: <https://en.wikipedia.org/wiki/Virtual_machine_escape>. While the example given is quite old, if you don't know the malicious code intimately, then you can't be sure it doesn't contain a modern equivalent.
Use a dedicated host connected to the internet through a dedicated router on a dedicated private network. This ensures that any unintentional bad behavior is treated the same as what's already knocking on your firewall's ports. However, this is not enough...
Don't process malicious files on a system connected to the public internet
==========================================================================
You could still unintentionally cause damage to external systems by running known malicious code on an Internet connected device. You may be able to mitigate this risk by inspecting all traffic through your firewall, running your own DNS server, emulated external services, etc. But as @Cort\_Ammon has already mentioned the malware may behave differently in different environments.
There may still be other liabilities... I would consult with a lawyer (I'm not a lawyer!) if you're still considering moving forward. |

In your quoted sentence **calling her fat** is a Gerund-Participle. So naturally the subject can be in genitive form or in plain form. So both of your sentences are grammatically correct and mean the same thing [*you hate calling her fat. Who is calling her fat? Them*]. **But note that even if your sentence #2 is grammatically correct, it's not very natural.** And it's not often that people will say/write something like this sentence.
You can analyze sentence #1 in a different way as well. You can think of the verb - *hate* - taking two complements - first, *them* and second, *calling her fat*. | >

This means "I hate it when they call her fat" (which sounds more natural).

This is much more grammatically strained; it took me a while to decide that it could actually make sense. It turns "calling her fat" into a noun. It would mean "I hate that they call her fat". I wouldn't use this form. |

47,091,604 | I thought, if we call autorelease on object, it decrements retain count and when finally pool drains it clears the object from autorelease pool. But how it crashes at run time when autorelease is called on object. Can anyone explain with example. | 2017/11/03 | [

] | Under MRR/MRC the programmer is responsible for retaining and releasing objects. If there are more retains than releases then an object stays alive, when the number of releases matches the number of retains then the object is freed, and if after that a further release is performed then a crash may occur.
An autorelease is just a delayed release, so it can cause a crash just like a release can. E.g. sample timeline:
>
> Create/retain object
>
>
> Use object
>
>
> Autorelease object - object stored in pool for later release
>
>
> Keep using object - fine as it's still alive
>
>
> Release object - object is freed, occupied memory can be reused
>
>
> ...
>
>
> Pool is emptied, object pointer now referencing long dead object is passed to release... boom.
>
>
>
This is just one scenario, there are others, e.g. Autoreleasing an object too many (more than it's been retained) times.
That's the *how*. To fix it either carefully review your manual memory management or go automatic and switch to ARC and just deal with manually avoiding leaks. | Tracking manual retain count issues can be done by the „Static Analyzer“ in Xcode. It explains why and where your memory issues occour. Run it and fix your issues. |

] | Signs point to **yes**.
We know that people communicating via Floo Network like this can be physically touched. One such example is when Mrs. Weasley gives Mr. Diggory some toast:
>
> "Never mind, Amos,” said Mrs Weasley. “Sure you won’t have a bit of toast or anything before you go?”
>
> “Oh go on, then,” said Mr Diggory.
>
> Mrs Weasley took a piece of buttered toast from a stack on the kitchen table, put it into the fire tongs, and transferred it into Mr Diggory’s mouth.
>
> “Fanks,” he said in a muffled voice, and then, with a small pop, vanished.
>
> *– Harry Potter and the Goblet of Fire, Chapter 11 (Aboard the Hogwarts Express)*
>
>
>
Now, if Mr. Diggory's head was only some sort of apparition or hologram, then such a feat would've been impossible. As his head was corporeal, Mrs. Weasley could presumably have reached down and grabbed hold of his head should she have wished to do so.
---
In addition, in *Deathly Hallows*, a Death Eater was able to grab hold of the Harry, Ron, and Hermione as they used the Floo Network to leave the ministry. I know this isn't *quite* the same thing, but it does seem at least a little relevant - reinforcing the corporeal nature of the Floo Network. | You theoretically can... but the fire would still be hot.
=========================================================
From Mrs Weasley giving Mr Diggory some toast (quoted in another answer but repeated here for ease of reading), we can see the head in the fireplace has a physical presence.

However, the fire around the head in the fireplace was still hot. Crookshanks tried to get close to Sirius but couldn’t because of the heat from the fire.

So, the head has a physical presence, but people can’t just reach out and touch it - they’ll get burned.
Umbridge likely transported just her hand using Floo Powder.
============================================================
When Umbridge’s hand came through the fireplace, it seems most logical that she did that by reaching into a Floo Powder fire and transporting just her hand over the Floo Network, similar to how people can stay where they are and transport just their heads.
>
> ‘Number twelve, Grimmauld Place!’ Harry said loudly and clearly.
> It was one of the most curious sensations he had ever experienced. He had travelled by Floo powder before, of course, but then it had been his entire body that had spun around and around in the flames through the network of wizarding fireplaces that stretched over the country. This time, his knees remained firm upon the cold floor of Umbridge's office, and only his head hurtled through the emerald fire …
> *- Harry Potter and the Order of the Phoenix, Chapter 29 (Careers Advice)*

From what we see of how Floo transport works, it seems likely that Umbridge stuck her hand in the fireplace and transported it alone.
>
> “Hermione gave a horrified gasp and leapt to her feet, still staring at the fire.

> A hand had appeared amongst the flames, groping as though to catch hold of something; a stubby, short-fingered hand covered in ugly old-fashioned rings.

>
> The three of them ran for it. At the door of the boys’ dormitory Harry looked back. Umbridge’s hand was still making snatching movements amongst the flames, as though she knew exactly where Sirius’s hair had been moments before and was determined to seize it.”

She probably could have pulled Sirius through the Floo Network.
===============================================================
It seems likely that, if she had been able to grab ahold of Sirius (her hand being in a Floo fire, and not a hot one), she’d be able to pull the rest of him through the Floo Network by his head. |

The clearest way to go about it, providing true numbers is to simulate a client that performs some sort of activity that mimics the real usage. Then have that client periodically use the website.
This presupposes that your website has a means to accept inputs that do not impact the real back end business. Crafting such interfaces requires some thought, but is not beyond the ability of a person who could put together the web site in the first place. The key points are to attempt to emulate as much using the real website as possible, but guard against real business impact. Basically it is designing for a special user (the tester).
So you might have a special user that when logged in, all purchases are bound to a special account that actually is filtered out to appropriately not demand payment and not ship goods. Provided the systems you integrate with all share an understanding of this live testing account, you can simultaneously test alongside of real production post-deployment.
Such a structure provides a huge benefit. You get performance of the real, live running system. Performance tends to change over time, and is subject to the environment. By fetching your performance numbers on the live system, in the same environment, you get a much better view of what real users might be encountering. Also, you can differentiate and track performance for different activities.
Yes, it is a lot more to design and set up; however, if you are in it for the long run, the benefits are huge. |

It can be built into a Java application and due to this feature, it monitors the functionality inside the app. Using this platform, it’s possible to get much more specific parameters for your Java app, than via external monitoring. In addition, it allows you displaying some statistics on your app homepage. Moreover, you can build in the app the graphs from JavaMelody, that essentially facilitates the app monitoring.

I don't exactly get the bold part, can anybody paraphrase it for me?
I have checked the Longman Dictionary and also Googled about that, but still, don't understand the meaning of "beating on your craft".
This is the results I found in the dictionary:
>
> * Beat on/against/at etc: to hit against something many times or continuously.

> *example: Rain beating on the windows.*
>
>
> * Craft: the skill needed in a particular profession.

> *example: The musician spends years perfecting his craft.*

450,864 | What are the lightweight options one has to persist Java objects ?
I'm looking for the easiest possible solution. I don't want anything fancy featurewise just something simple that works with reasonnably simple objects (some collections, relationships and simple inheritance) and doesn't bring too much apparent complexity (if any) to the existing codebase.
The options I'm aware of include Hibernate and frameworks such as EMF but they sound (and have been experienced to be) too complex and time-consuming. I'd like something out of the box, preferably file oriented than dababase oriented, that I can just put on top of my plain old java objects.
This is a newbie question, thanks in advance for any tutorial-like, context clarifying guidance. | 2009/01/16 | [

You should be able to get a test system up and running in less than a day. It's only when you want the more advanced features where it starts to get steeper. I would recommend you definitely take a look, I mean what's a day if you end up not choosing it?
Having said that, have you considered just serializing your objects directly to disk if you just want something quick n dirty? |

] | Imagine that IAS measures the number of air particles hitting your aircraft per second. As you get higher the air is thinner — there are progressively fewer air particles around the higher you go so to get the same number of particles hitting you per second (ergo the same IAS) you need to move faster through the air - your TAS increases. | Although, it is a backwards way of thinking about it, consider that the True AirSpeed is not changing with altitude for an aircraft keeping a constant speed. In actuality, the Indicated AirSpeed is what is changing. This is due to the IAS being measured by using Ram Air Pressure inside of the pitot tube. The RAP is directly related to the density of the air. The higher the air density, the higher the RAP at the same speed.
More gas molecule mass in the air is entering the pitot at any given time at lower density altitudes (higher air density). Think of it this way. A single bb would have less impact than 100 shot gun pellets fired at the same muzzle velocity.
Your pitot static system is actually measuring the impact of the air molecules and converting that into IAS. In order to fly at a constant IAS at a higher altitude, you have to increase your TAS because the air is less dense (fewer air molecules). |

] | Imagine that IAS measures the number of air particles hitting your aircraft per second. As you get higher the air is thinner — there are progressively fewer air particles around the higher you go so to get the same number of particles hitting you per second (ergo the same IAS) you need to move faster through the air - your TAS increases. | Inflight, the IAS is measured via the pitot/static system and is displayed on your ASI, the primary airspeed display instrument. TAS cannot be directly measured by a probe or transducer, it has to be calculated by using the IAS as a starting reference.
**IAS:** The pitot pressure is static pressure + the pressure on account of air molecules impinging on the pitot probe from the direction of flight. If the air density reduces, as it does with altitude, in order to fly a given IAS, it requires the airplane to fly faster through the thinner air for the pitot to experience the same pressure and indicate the same IAS. This faster speed is your TAS. Aerodynamic forces such as lift, drag, propeller torque/thrust etc. all depend on the flow of air molecules over the wings and body of the airplane and stall speeds, maneuvering speeds and limit speeds all relate therefore to the IAS.
**TAS:** is a calculated speed, as there is no instrumentation to physically measure it - in it's simplest form it is arrived at by plugging the IAS into a formula and based on the International Standard Atmosphere. TAS is useful for planning and actual navigation as it is your true speed in relation to the ground in nil winds.
**Atmospheric Air Density as per ISA:** As per the Standard atmosphere around 6600ft the density of air is about half of what it is at Mean Sea Level, at 12000ft around a quarter, and around 18000ft it is a tenth of the sea level density and so on.
You memorized "TAS increases as altitude increases" but the statement is incomplete in that it gives no info on the reference speed you are flying on your ASI. So a more complete statement is "IAS being constant, TAS increases as altitude increases".
**POH 'Contradiction':** Your C-152 POH Cruise Performance table ***seems*** to indicate a reducing TAS as altitude increases. This is because the page does not indicate the IAS to be flown, instead it gives you an RPM setting for level flight and the resultant TAS (and inflight we accept the resultant IAS). Take 2100rpm, the TAS is:
86KTAS at 2000ft
85KTAS at 4000ft
84KTAS at 6000ft
83KTAS at 8000ft
82KTAS at 10000ft
81KTAS at 12000ft
*Seems to reduce with altitude*, but [calculating the IAS equivalent to the TAS and Alt at ISA](https://aerotoolbox.com/airspeed-conversions/) using the 'aerotoolbox' webpage gives:
86KTAS at 2000ft = 83KIAS
85KTAS at 4000ft = 80KIAS
84KTAS at 6000ft = 77KIAS
83KTAS at 8000ft = 74KIAS
82KTAS at 10000ft = 71KIAS
81KTAS at 12000ft = 67KIAS

In the cockpit you can either fly a speed on the ASI (adjusting the RPM to suit) or you can fly the manufacturers recommended RPM and accept the resultant speed on the ASI.
As per the POH page, you input altitude and RPM (with mixture leaned) and the table gives you the Power, TAS, and Fuel consumption. The chart gives you this data for an airplane weight of 1670lbs and various RPM settings of the engine at even thousands of feet altitude ranging from 2,000 to 12,000 ft. (And for ISA, ISA-20degC, ISA+20degC.)
An input of altitude - RPM - OAT/ISAdev gives the TAS and fuel consumption per hour. These are the parameters you need alongwith forecast winds to make out a navigation and fuel flight plan. TAS and Wind gives Groundspeed/leg times and Heading to steer, and further with Fuel cons/hr it gives you the fuel for trip etc. *The fact that the table outputs no IAS is of no particular disadvantage in the cockpit.*
The data could have been shown by using a fixed IAS strategy, replacing the RPM settings with different IAS values in which case you would input altitude, IAS, Temp/dev the chart would output an RPM, TAS and Fuel consumption. |

Aircraft are more efficient at high altitude because of this simple fact. Providing the engine can produce enough power, any aircraft will fly faster and further, without burning more fuel, if you fly at a higher altitude.
Your C-152 chart shows this quite clearly.
2000’ 59% power = 91 KTAS @ 4.8 GPH
12,000’ 59% power = 97 KTAS @ 4.8 GPH |

] | To the extent that 75% cruise power available is constant with increasing altitude, it's simply that TAS goes up because the constant HP has less and less resistance to work against as the air thins out, while you are able to maintain 75% cruise power by opening throttle more. On a non-turbocharged engine, that is possible up to the point at which the engine is maxed out making cruise power (75%), somewhere around 8000 feet give or take (where the available manifold pressure at wide open throttle drops to about 22").
At this point the engine is wide open throttle just to make 75% power and is maxed out there. As you go above 8000 ft with wide open throttle, by the time you get to 10000 ft it can produce only 68 thrust HP (per the chart, in standard conditions) with wide open throttle and maximum TAS drops to 103 kt.
If the engine had turbocharging, it would be able to maintain 75 HP (75% of 100) to some much higher altitude and you could climb to say, 15000 ft, still making 75 HP in the even thinner air thanks to the turbo, and your TAS would be up to something like, say, 115 kt (you would also need a constant speed prop to exploit that power, but that's another issue). | Although, it is a backwards way of thinking about it, consider that the True AirSpeed is not changing with altitude for an aircraft keeping a constant speed. In actuality, the Indicated AirSpeed is what is changing. This is due to the IAS being measured by using Ram Air Pressure inside of the pitot tube.
