] | That looks like a paradox, but it isn't.
The assertion is so vague that it is true even if Pinocchio's nose doesn't grow *immediately*.
Even if he says: "My nose will grow immediately" that's a vague assertion, when does "immediately" start and end as a time lapse?
If he is more specific and states: "My nose will grow in the next five minutes" then the nose can make a suspension of disbelief, if he tells a lie in those five minutes then the nose will grow and the first assertion will be true, if he doesn't then the first assertion will be proved as false and if falsehood is considered as a lie then the nose will grow after the five minutes.
Everything that is false is a lie? That depends on some definitions, but if Pinocchio says something that is false and a mistake then the nose may (or may not) consider that Pinocchio is implicitly stating to be sure about something that he is not sure and actually wrong, hence a lie. That may be a question for Geppetto.
Nothing is true or false until it is.
If Pinocchio succeeds in creating a paradox (either the liar's paradox or some other paradox) then the nose will not react to that. A paradox is something that cannot be true and cannot be false and the nose grows on falsehood, right?
No matter which logic and assumptions ([OWA](http://en.wikipedia.org/wiki/Open_world_assumption) and [CWA](http://en.wikipedia.org/wiki/Closed_world_assumption) for instance) that nose follows, in any logic where there can be paradoxes it is clear that [the middle cannot be excluded](https://en.wikipedia.org/wiki/Law_of_excluded_middle). | **Bad question**. Stated differently, you have constructed a paradoxical world. Check out [self-reference](http://plato.stanford.edu/entries/self-reference/). I will take your question to be equivalent to the [liar paradox](http://plato.stanford.edu/entries/liar-paradox/):
>
> This sentence is not true.
>
>
>
Something tricky is going on here: *recursion*:
>
> This sentence is not true.
>
>
>
Let me do a substitution, "This sentence" → "This sentence is not true.":
>
> "This sentence is not true." is not true.
>
>
>
But wait, what is being pointed to by "This sentence"? The substitution did not bring any clarity! The problem here is that there is an infinite regress, caused by *self-reference*. This kind of paradox shows up elsewhere, like [Russell's paradox](http://en.wikipedia.org/wiki/Russell%27s_paradox), which attempts to construct the set *R*, with membership criterion: "all sets which do not contain themselves as a member".
1. If *R* contains itself, it is not a member of *R*.
2. If *R* does not contain itself, it is a member of *R*.
This might take a while to completely wrap your head around, but it is a deep result of what is now called [naive set theory](http://en.wikipedia.org/wiki/Naive_set_theory). In order to circumvent this problem, [axiomatic set theories](http://en.wikipedia.org/wiki/Set_theory#Axiomatic_set_theory) where developed which could not produce such paradoxes. However, they lose something: they are *axiomatic*, and thus not ambiguous like natural language. And yet, there seems to be something deep to this ambiguity. I won't go into that now, but it would make a good separate question.
There is a theory of computation aspect to self-reference, which shows up as Turing machines being able to [print out their own description](http://www.eecis.udel.edu/~case/self-ref.html). This gets at the idea of *self knowledge*. And yet, Thomas Breuer's [The Impossibility of Accurate State Self-Measurements](https://homepages.fhv.at/tb/cms/?download=tbPHILSC.pdf) questions this whole perfect self-knowledge enterprise. This Turing machine self-reference thing is very important; it shows up in the [Halting Problem](http://en.wikipedia.org/wiki/Halting_problem), which presents a huge obstacle to provability of Turing complete systems, which means we cannot guarantee properties we'd like to guarantee (like that your phone won't crash).
Douglas Hofstadter introduced the idea of [strange loops](http://en.wikipedia.org/wiki/Strange_loop) in his [Gödel, Escher Bach](http://en.wikipedia.org/wiki/G%C3%B6del,_Escher,_Bach). The book is a layman's introduction to some neat theory of computation issues. I do not pretend to understand this 'strange loop' idea, but it definitely has to do with self-reference. It may be that consciousness itself has to do with self-reference; indeed, it is hard not to. So there's a lot to this liar paradox! |
190,260 | I saw this around 7-8 years ago on Toonami/Cartoon Network and I'm still not quite sure it was an anime or an animated TV show.
I watched this series completely in Spanish since that's my main language but sadly I was too young to remember anything else about the animation style or quotes from it.
The opening is the thing I'm less sure of but it basically recapped the story, and it was something like...
* a king having a belt (a belt? could be something else) that had elemental gems on it,
* the antagonist tried to get the gems so the king hid the gems all around the world, now the villain's trying to get it back and the heroes are trying to get them so the villain doesn't get them.
I remember 3 episodes, to an extent,
* The first was the heroes being trapped on quicksand, and they end up meeting with an old man and an old woman that save them, they spoke in gibberish and gave them food and a place to stay. Some of the protagonists were suspicious about this but were obviously told they were exaggerating. Eventually they found out the old people were speaking backwards and were trying to eat them, the old couple transform into monsters and they defeat them.
* Another episode is the heroes looking for the water gem and finding themselves on a beach with a huge castle floating right in the middle of the water. They tried their best to reach it (not sure how they did?) only to have one of them reach the castle and find a huge blue dragon with the gem on it's forehead.
* The next episode is just the rest of the characters getting to the castle and defeating the dragon. | 2018/06/28 | [

It *was* aired on Toonami, and it has roughly the plot you described: a very bad fellow from the past is vanquished by an ancient hero and his armor is split into pieces and sent around the globe for safekeeping. Big bad returns in the modern era and seeks his armor, but 5 young warriors stand in his way and anime things ensue:

] | Pies like that are not commonly eaten in Britain (and probably not in other English speaking countries). A quick check of the dictionary confirms that the word "paschalilla" is not used in English. So you have one of the common translator's dilemmas: a concept that does not exist in the target language.
Here you should consider your audience. Are they people who are interested in Latin American cuisine? If so then use "pascualina" but explain its meaning the first time it is used. For example from recipe book:
>
> The Pascualina pie or chard pie is simple to make, delicious and very healthy. This Pascualina is typically Argentinean...

On the other hand, if your readers are not likely to be interested in Latin American food, you can just describe:
>
> Maria cut each of them a slice of spinach and egg pie as the Church bells rang out for Easter...

3,711 | I'm specifically referring to the loss due to the pistons pulling air through a mostly closed throttle while cruising at highway speeds in a gasoline engine.
To give an example, I've always wondered why this wouldn't be more economical fuel-wise:
Add another gear to the gearbox, say a sixth gear to a 5-speed car. This gear would be useless for accelerating whatsoever; it would be such a high ratio that at 65 MPH, wide-open throttle, it would hold the vehicle at a steady pace or only slightly accelerate. This would reduce much of the pumping losses from making the pistons suck through a nearly closed throttle, and would seemingly allow for better fuel economy, due in part from both 1) lower RPM so less friction loss and 2) less pumping loss.
I am aware other things may need to accompany this; for example WOT in 6th gear should not richen the mixture as WOT does normally, etc., so let's say the car was produced from the factory with the computer and associated electronics accommodating the fuel-gear.
However, this has never been implemented. Is it just not efficient? If not, why not? Or would it be an irritation to consumers that expect a more responsive car, requiring a shift to accelerate? Too expensive to add the gear, or just never been tried? | 2012/06/07 | [

You would waste more energy having to use a wide open throttle for cruising - instead many cars have an overdrive. In my car, 6th gear at motorway speeds runs at about 2,200rpm which is hardly doing any work. | I can think of a couple reasons (mostly apply to automatics though)...

The point is that the situation you're describing constantly keeps the engine at it's maximum torque/load. It's highly probable that it's more efficient there(if the AFR would be managed for that) so i understand your idea, but there's one big downside.
Torque is just a slightly different variation of force. Imagine what will happen if all the parts in the engine constantly have to sustain the forces that come into play when the engine operates at maximum torque. They can't endure that stress for extended periods of time. Things will wear out rather quick.
Shift in top gear at 70km/h or slower so the engine revs at 1000rpm, and put the pedal to the metal. The engine will growl in protest without the car accelerating. It doesn't sound healthy, and it isn't. At 2000rpm the engine has to deliver only half of the torque, and 2000rpm isn't even much. The engine will sustain that situation for much much longer, but yes it's probably a bit less efficient.
Diesel generators manage their engine like you proposed. They operate at a constant rpm and maximum torque, because that's where they achieve maximum efficiency. But they're designed for that, with that situation in mind. A car is not, as it isn't needed. It would make the engine a lot heavier at the cost of material, fuel consumption, road tax, etc. |

I suspect that this is not implemented in consumer cars because it is not very "easy" to use and is not as economical for manufacturers to provide.
As you can see from the above examples, to really be efficient this method favors having multiple smaller engines all running at mid to high throttle over having one single powerful engine running at a range of throttle levels.
The costs for manufacturers to provide a vehicle with multiple engines to efficiently account for each speed range would be enormous and is probably not worth the savings imparted to the customers through fuel savings. Not to mention the increase in maintenance by a factor of at least the number of engines in the vehicle.
But what if we said screw the multiple engines, lets just try to make the one engine more fuel efficient by modifying the gearing?
Then the car, at any given speed, will have one optimal gear for acceleration and another optimal gear for cruising for fuel efficiency.
I think on average this method might gain the average person about 1 mpg, maybe 2, at the cost of real-time throttle responsiveness. I think if you try to balance the scale between throttle response vs 1-2 mpg, the benefits of the mpg over millions of people is definitely there (1-2 million miles or roughly 50k-100k gallons of gas or roughly $200k-$400k per million people), but is it really significant enough to outweigh the few accidents that may have been prevented by having better throttle response (and the added "comfort" of having some throttle cushion during normal driving)? It would really depend on the statistics and analysis therein, but I would guess probably not.
Additionally, especially for automatics, this method would have to be heavily controlled by the computer to be acceptable for use by everyday consumers and would cost that much more money in R&D, testing, and production as another feature they provide. If a feature is provided but does not work correctly or smoothly enough then it damages the brand and might cause direct damage through warranty work or recalls.
Honestly, I think you have a better handle on pumping loss and frictional loss in gasoline IC engines than the other responders. Might have had better responses in Engineering SE. |

I think if you try to balance the scale between throttle response vs 1-2 mpg, the benefits of the mpg over millions of people is definitely there (1-2 million miles or roughly 50k-100k gallons of gas or roughly $200k-$400k per million people), but is it really significant enough to outweigh the few accidents that may have been prevented by having better throttle response (and the added "comfort" of having some throttle cushion during normal driving)? It would really depend on the statistics and analysis therein, but I would guess probably not.
Additionally, especially for automatics, this method would have to be heavily controlled by the computer to be acceptable for use by everyday consumers and would cost that much more money in R&D, testing, and production as another feature they provide. If a feature is provided but does not work correctly or smoothly enough then it damages the brand and might cause direct damage through warranty work or recalls.
Honestly, I think you have a better handle on pumping loss and frictional loss in gasoline IC engines than the other responders. Might have had better responses in Engineering SE. |
3,711 | I'm specifically referring to the loss due to the pistons pulling air through a mostly closed throttle while cruising at highway speeds in a gasoline engine.
To give an example, I've always wondered why this wouldn't be more economical fuel-wise:
Add another gear to the gearbox, say a sixth gear to a 5-speed car. This gear would be useless for accelerating whatsoever; it would be such a high ratio that at 65 MPH, wide-open throttle, it would hold the vehicle at a steady pace or only slightly accelerate. This would reduce much of the pumping losses from making the pistons suck through a nearly closed throttle, and would seemingly allow for better fuel economy, due in part from both 1) lower RPM so less friction loss and 2) less pumping loss.
I am aware other things may need to accompany this; for example WOT in 6th gear should not richen the mixture as WOT does normally, etc., so let's say the car was produced from the factory with the computer and associated electronics accommodating the fuel-gear.
However, this has never been implemented. Is it just not efficient? If not, why not? Or would it be an irritation to consumers that expect a more responsive car, requiring a shift to accelerate? Too expensive to add the gear, or just never been tried? | 2012/06/07 | [

I suspect that this is not implemented in consumer cars because it is not very "easy" to use and is not as economical for manufacturers to provide.
As you can see from the above examples, to really be efficient this method favors having multiple smaller engines all running at mid to high throttle over having one single powerful engine running at a range of throttle levels.
The costs for manufacturers to provide a vehicle with multiple engines to efficiently account for each speed range would be enormous and is probably not worth the savings imparted to the customers through fuel savings. Not to mention the increase in maintenance by a factor of at least the number of engines in the vehicle.
But what if we said screw the multiple engines, lets just try to make the one engine more fuel efficient by modifying the gearing?
Then the car, at any given speed, will have one optimal gear for acceleration and another optimal gear for cruising for fuel efficiency.
I think on average this method might gain the average person about 1 mpg, maybe 2, at the cost of real-time throttle responsiveness. I think if you try to balance the scale between throttle response vs 1-2 mpg, the benefits of the mpg over millions of people is definitely there (1-2 million miles or roughly 50k-100k gallons of gas or roughly $200k-$400k per million people), but is it really significant enough to outweigh the few accidents that may have been prevented by having better throttle response (and the added "comfort" of having some throttle cushion during normal driving)?

Honestly, I think you have a better handle on pumping loss and frictional loss in gasoline IC engines than the other responders. Might have had better responses in Engineering SE. | Sorry for the necromancing here, but i stumbled upon this thread and i think there's another important reason why this shouldn't be done, and why it probably isn't even tried out by manufacturers. The point is that the situation you're describing constantly keeps the engine at it's maximum torque/load. It's highly probable that it's more efficient there(if the AFR would be managed for that) so i understand your idea, but there's one big downside.
Torque is just a slightly different variation of force. Imagine what will happen if all the parts in the engine constantly have to sustain the forces that come into play when the engine operates at maximum torque. They can't endure that stress for extended periods of time. Things will wear out rather quick.
Shift in top gear at 70km/h or slower so the engine revs at 1000rpm, and put the pedal to the metal. The engine will growl in protest without the car accelerating. It doesn't sound healthy, and it isn't. At 2000rpm the engine has to deliver only half of the torque, and 2000rpm isn't even much. The engine will sustain that situation for much much longer, but yes it's probably a bit less efficient.
Diesel generators manage their engine like you proposed. They operate at a constant rpm and maximum torque, because that's where they achieve maximum efficiency. But they're designed for that, with that situation in mind. A car is not, as it isn't needed. It would make the engine a lot heavier at the cost of material, fuel consumption, road tax, etc. |

] | Actually, no form of "behave" ever has a passive meaning.
In modern English, the verb "behave" is always used either as an intransitive verb ("he behaved well") or as a reflexive verb ("Behave yourselves!"). Neither of these types of verbs have corresponding passive constructions, so passive uses of "behave" (or its inflected/derived forms) simply do not exist.
The past participle form "behaved" simply has a stative active meaning in this case, like the past participle form "fallen" which corresponds to the intransitive verb verb "fall," and can mean "in the state resulting from the action of falling".
There isn't as big a difference in meaning between "behaving" and "behaved" as there is between "falling" and "fallen." Unlike "fallen", "badly behaved" doesn't particularly imply being in a state *resulting* from bad behavior; it just means "being in a state of bad behavior". In general, "badly behaved" is more idiomatic and more commonly used than "badly behaving", especially in attributive position with an adverbial modifier as in your example.
It seems to me the word "behaving" might be used to emphasize the in-progress nature of the behavior (as in "There was a badly behaving customer in the store"; you don't know whether the customer is habitually badly behaved, just that their behavior at that moment was impolite). But that's just a guess of mine; I don't see any clear difference in meaning.
By the way, according to [Merriam-Webster](https://www.merriam-webster.com/words-at-play/6-common-hypercorrections-and-how-to-avoid-them/hyphenating-ly-adverbs), many style guides recommend never using a hyphen after a *-ly* adverb. [Sven Yargs' answer](https://english.stackexchange.com/a/367336/77227) to an ELU question about hyphenation also supports this proscription. So "badly behaved" and "badly behaving" are probably better ways to write these phrases, even in attributive position. | Just want to point out that adverbs, typically ending in "ly", do not need to be hyphenated as compound modifiers.

Vin: 24-28 VDC

"https://electronics.stackexchange.com/users/328340/"
] | As noted by others, the circuit you've implemented only provides reverse-polarity protection. I've seen this layout called an "ideal diode" MOSFET because the voltage drop is in the tens of mV, ten times lower than even a signal Schottky could provide. (Power diodes that could handle your load current, of course, are even more lossy.)
It works because of the body diode in the pMOS. Under proper polarity, the body diode conducts. The zener diode / resistor bridge then pulls down the gate voltage relative to the source, which biases the pMOS well into its operating region, where many power pMOS devices will have an on resistance of a couple dozen mΩ. Under reverse polarity, the body diode blocks, the pMOS gate voltage remains equal to the source, and no current can flow.
The solution to the overvoltage problem requires a second MOSFET. Because the pMOS in your circuit is "backwards", the body diode will always conduct if the drain-source voltage exceeds a minimal threshold. A second power MOSFET, connected "normally" and itself controlled by some zener diode reference voltage, can switch off the circuit when necessary.
[simulate this circuit](/plugins/schematics?image=http%3a%2f%2fi.stack.imgur.com%2fBq1ro.png) – Schematic created using [CircuitLab](https://www.circuitlab.com/)
In this circuit, M1/D1/R1 form the reverse voltage protection circuit you already have. M2 is the load switching MOSFET which, under normal circumstances, is biased deep in its conducting region by the D3/R3 divider, with a source-gate voltage of 10 V.
M3 is a low-power MOSFET. Under normal circumstances, D2 is not conducting, R2 pulls M3's gate voltage up to its source voltage, and M3 is off. However, when the D2 cathode voltage exceeds its zener voltage (in this case chosen to be a little higher than 24 V), D2 starts to conduct, clamping the M3 gate voltage. Once M3's source-gate voltage drop is high enough, M3 conducts, D3 is bypassed, M2's source-gate voltage drops to zero, and the circuit shuts off.
Resistor values and zener voltages are for illustration. You'll need to match your resistors, zeners, and MOSFETs carefully to make sure your circuit doesn't turn off prematurely. A slight overvoltage combined with poorly-chosen components may result in a not-completely-off M2, which will significantly increase its on resistance, and thus its temperature, in a way you may not have expected. | It all depends on the requirements of your application. The advantage of the shown circuit is that a reverse condition is not destructive (unlike blowing a fuse) and the nominal condition has very little forward voltage drop compared to other circuits like a single in-series diode.
By the way: The only thing that is protected against over-voltage in the shown circuit is the gate of the MOSFET. The load isn't protected against over-voltage at all.
If you have more requirements e.g. inrush current limitation or your load needs to work no matter how your battery is connected, the circuit will become more complex, of course.
Or you have a lot of capacitance in your load and - when disconnecting the battery - you want to prevent that capacitance from discharging into other loads that are connected in parallel, etc... |

6. Select cell A1 on the blank worksheet.
7. On the Ribbon's Home tab, click Paste.
8. Delete the sheet that contains the pasted copy of the pivot table.
Your custom PivotTable style now appears in the PivotTable Styles gallery,
in the new workbook.
**Excel version 2016**
Unfortunately, in Excel 2016 the above method does not work and the custom
pivot table style is not copied. The following method works in
Excel 2016 and also in Excel 2013.
1. Open the old workbook with the pivot table that has the custom style applied.
2. Open the new workbook where you want to add that custom style
3. Position the workbooks, so you can see the sheet tabs in both files
4. Press `Ctrl` and drag a copy of the pivot table sheet from the old workbook into the new workbook.
5. The custom style is now copied into the new workbook, and you can delete the sheet that you copied from the old workbook.

1,266,871 | I went to the effort of creating a custom pivot table design, to match my companies work colours.
**I'm looking for a way to save a custom table style (not Workbook) as a template, so it can be used in other workbooks.**
I have done this with several charts, which can then be used again, so was hoping it is also possible with a Pivot Table .
I have found a work around for this, I can copy the original created template and paste it into a new workbook, the design is then available to use, but surely there must be a way of saving the actual design ?! | 2017/11/09 | [

] | There is, but it ain't pretty:
1. Copy a Table/PivotTable that uses the new Table Style into a new
blank workbook.
2. Setting that Table/PivotTable Style as the Default Style
3. Delete that Table/PivotTable
4. Save the workbook as an Excel Template in the Startup folder, so
that Excel will use this workbook – and your beautifew new Custom
Table/PivotTable Style – as a template whenever you create a new
document.
Read more at my blogpost at <http://dailydoseofexcel.com/archives/2015/02/27/custom-table-styles/> | Another way to do this is to right click on the tab that contains the pivot style you created and want to use.
1. Once you right click, select 'Move or Copy'.
2. Once you select that option, select the workbook you want this pivot table style in.
3. Select 'Move to End'.
4. Select 'Create Copy'.
This creates a copy to the other workbook and allows you to use your personal template style on any pivot table in the workbook. If you click on the pivot table and go to the design tab at the top, you will now see your style available to use. Once you have selected your created style, you can then delete the copy at the end of the workbook. |

In case you want to create some additional functionality from scratch the easiest way is to [create a custom web part](http://msdn.microsoft.com/en-us/library/ms452873.aspx) and then [add it to a SharePoint page](http://office.microsoft.com/en-us/sharepointserver/HA011605831033.aspx). | I think you want to include an aspx page to call either using an AJAX include or to be able to use the MOSS Object Model without having to add references etc?
if so then the following steps are necessary:
1. navigate to 12\layouts\
2. create a folder for the asp.net files
3. put the inline code files in
4. From sharepoint you can add a page viewer web part and reference it with the following url \_Layouts//Filename.aspx
This technique will only work with inline code, if you wish to compile your code then you would create the site as normal and then add an application folder within the virtual directory of that particular site for example my site is called intranet:
1. navigate to c:\inetpub\wwwroot\wss\intranet
2. add your asp.net folder to this as a sub folder
3. in inetmgr right click the folder and create an application for it (use the same app pool as the sharepoint site)
4. ensure ALL DLLs from the sharepoint site bin folder exist within the apps bin folder or it will throw an error.
**However, I would only ever use these methods as proof of concept and would ultimately use web parts, custom features and workflows to carry out the same functions.** |

44,164 | I'm designing a game with loyalty mechanics similar to Secret Hitler or Battlestar Galactica. In it I have character abilities. One of the abilities will allow a player to choose three players, take their loyalty cards and shuffle them, look at the loyalty cards, and then RETURN them to the correct player. Basically the goal is to have it so the player with this character (and ONLY that player) can look at 3 people and know how many of them are on the bad team and how many are on the good team, without knowing which one is which. Now obviously there are a few problems with this, how can I have it so that who each loyalty card belongs to is hidden from the player using the ability, while still being able to return them to the right players?
Now I have ideas on how to achieve this, but I want to do it in the fewest amount of steps possible, hopefully without adding any extra cards other than the basic loyalty cards. | 2018/11/24 | [

C adds his salary and gives the final result to you.

225,743 | **Description:**
We are using Einstein Analytics to create more insight on products our customers have, this requires creation of Einstein Analytics dataflows, datasets, dashboards and apps.
We have a use case to help our users understand profitability/loss at first sight. In order to achieve this goal, we created a dataflow to collect the data on project daily. This project includes data such as exchange rate of the day, price of the product, volume of sales and revenue and a date.
[](https://i.stack.imgur.com/R7Gtw.png)
**Problem:**
The dataflow we created stores the data in a table and extends the table by adding new rows, daily. We aim to store 365 snapshots, so the last 365 days. Currently we can use the analytics dashboards to display the snapshot details side by side.
[](https://i.stack.imgur.com/yv5gu.png)
**Questions:**
We are seeking answers for which path to follow.
(1) What would be the best practise to show such a change using Einstein Analytics? Using what type of charts with what kind of customisations?
(2) Would it make sense to calculate the difference using the dataflow and store them on the table?

Using the compare table I managed to create the logic to have two different revenue sums and the difference in between as change.
[](https://i.stack.imgur.com/RQi56.png)
However now I fall into an another problem. In the dataset, I have an extra field called 'Snapshot Date in Text' to enable the user pick multiple dates for comparison within dashboard. However in this use case, I need two fields for selections of 'Snapshot Date' as 'Select Snapshot #1' and 'Select Snapshot #2'.
As expected the filters are overriding each other, so I can't really associate the 'Select Snapshot #1' selection with 'Sum of Revenue Snapshot #1' and 'Select Snapshot #2' selection with 'Sum of Revenue Snapshot #2'.
To fix this, I thought about creating another dataset and combine them using SAQL statements. However I fall into an another issue.
[](https://i.stack.imgur.com/er9Hm.png)
The C field is not correctly calculated since I can make to values in the same row. Any ideas how to fix any of the issues above? | 2018/07/19 | [

] | It seems like this could be done with a compare table and KPIs on a dashboard.
For example, column A in a compare table is yesterday's data. Use a relative date filter to get the data from "day - 1" to "day - 1".
Column B would be todays data, also with a relative date filter of today to today.
Column C would be a formula of B-A to get the differences. You could go a step further and use conditional formatting on Column C. Negative values could be in a red text and then positive in green.
[](https://i.stack.imgur.com/63lNy.png)
* **Note**: I am showing months in the filter as I don't have days
For the dashboard, you can drop a couple of KPIs. The first would show today's profit. The second, which you could make smaller would use Column C with the Change
[](https://i.stack.imgur.com/mWR3K.png)
You could even get more advanced and build a SAQL statement that dynamically generates the text based on whether the change is positive or negative. You can add characters like ▲ or ▼ to the text as well. Then use a binding statement to dynamically change the label of the KPI widget.
If you need more flexibility with the date that is used, add a date picker or list of dates in a select to the dashboard. A binding statement can dynamically change the filter based on the selected date.
Alternatively, if you are looking to show each date and the change from the previous as a line or bar chart, you would want to add the differences to the dataflow.
Take a look at the computeRelative transformation. It would allow you to find the previous days record in the data flow. You can pull the value into the current record. Then use a computeExpression to calculate the difference.
Be sure to take into account cases where you don't have a value (nulls) and use a coalesce statement to turn null into 0. | Using the suggestions of Carl Brundage, I modified the compare table, disabled the faceting and bound the steps with list selectors in a custom fashion. The bottle neck was the binding filters and the steps.

Then you can access all of the previous page's variables using Page.PreviousPage. If Page.PreviousPage is null, you know the user came to the page directly and you should process page 2 with that in mind.
I can't really recommend it though, because with Server.Transfer you don't update the URL in the browser and CrossPagePostBack makes everything a postback, which can lead to problems like the back button not working "normally". |

**Update:**
Or perhaps a combination of ViewState and SessionState.
Here's an example sequence:
* On Page 1, user chooses "Red". Value is stored in SessionState.
* User navigates to Page 2. Value is read from SessionState and stored in ViewState of Page 2.
* User opens a second Page 1 in a new tab and chooses "Blue". Value is stored in SessionState, so "Red" is replaced with "Blue".
* User navigates to Page 2. Again, value is read from SessionState and stored in ViewState.
* User returns to original Page 2 (the one on the first tab) and performs a PostBack. Value is read from **ViewState**. Value is still "Red".
* User returns to second Page 2 (the one of the second tab) and performs a PostBack. Value is read from **ViewState**. Value is still "Blue".
In other words, use SessionState for *transitions* between pages. Use ViewState for PostBacks of same page.

* *If* you can use Post (eg: you can keep from manipulating the URL on the client), **hidden input tags** can do the job well. You'll certainly want to encapsulate this, since doing it manually would be a huge pain. Otherwise:
* *If* you're using **ViewState**, you could use that. Otherwise:
* You get the values or an ID (which would be better. see below) into the **URL**. A last resort, because the human will be able to screw this up. Or they might bookmark it and cause confusion when they come back a week later.
**If the values cannot be sent to the client**, then you need to pass a "PageSessionID" or something down to the client. This ID is either a guid (better if security is an issue) or some value you get in a way to guarantee uniqueness.

If it matches and was a null token, the token is created and stored in the key object and in the viewstate.
If another page comes in with the same query string matching the guid key, it can try to claim the appstate key object but will fail unless has the same userid/timestamp/PageToken in the key object having got the page token form the viewstate. And if everything matched, updates the timestamp. If the timestamp is too old, 15 minutes, the the key object can be stolen. and If the old page comes back looking for it the page token will no longer match and claiming will fail due to either the timestamp too old or the page token not matching.
The token can be null or valued when the key object is created. If it starts out null when created, then anyone can claim with a new token but must match the timestamp pretty close.
Then the related key object which can be a larger size, is stored in the session using the page token as the key into session data such as a serializeable dictionary in case this needs a sql backing store.

2. Use this guid as the session key that stores a struct with all the variables etc. for that page.
3. You can now pull information for a specific page "rendering" and passes data to the session struct to the new "rendering" in the code-behind.
This is similar to what *ViewState* does automatically.
**EDIT**
*Comment response*
I don't think that's possible *as* you described it.
In your question you mentioned page 1 to 2 *navigation*. If the user types in the URL for page 2 in the browser then how do you tie that current page 2 rendering with the previous page 1?
You need something to do so, unless the code-behind can search a list of incomplete workflows that have stopped at page 1 and uses that as the *previous guid* value for the new page 2 rendering.

The page token is a guid but can be null if the page token based session object is pre-created for another page in the same session [so can pass more data to the new page] or the token can be valued the session object is created for the current page. When the session object is created based on the key, it can be used to store normal session type data, which is now unique for this key, rather than shared across the entire session.
So the first page creates the key object in app state w/o a pagetoken and then links to the new page that ckaims the key object from appstate using its querystring with the key, and by matching userid/timestamp/PageToken with null or a valued token. If it matches and was a null token, the token is created and stored in the key object and in the viewstate.
If another page comes in with the same query string matching the guid key, it can try to claim the appstate key object but will fail unless has the same userid/timestamp/PageToken in the key object having got the page token form the viewstate. And if everything matched, updates the timestamp. If the timestamp is too old, 15 minutes, the the key object can be stolen. and If the old page comes back looking for it the page token will no longer match and claiming will fail due to either the timestamp too old or the page token not matching.
The token can be null or valued when the key object is created. If it starts out null when created, then anyone can claim with a new token but must match the timestamp pretty close.
Then the related key object which can be a larger size, is stored in the session using the page token as the key into session data such as a serializeable dictionary in case this needs a sql backing store.
So we are able lock data across the entire web app all users, we can expire and reclaim the locks after say 15 minutes of non use, and have key based data for tabs, pages, new sessions and different browsers. |

] | I figured out a solution :
1. **Using Javascript assign a unique id like a guid to the browser window / tab** by assigning the guid value to the **window.name** property. window.name property is unique to each browser window/tab and won't be shared across the windows.
2. **Using the guid as the key, read and write data to your ASP.NET session via a webservice**. Since javascript does not have access to asp.net session, you will need to use a webservice and call it's method through javascript.
The data can be transfered between javascript and webservice via JSON. | It sounds like you want each page to keep it's own values, separate from each other.
* *If* you can use Post (eg: you can keep from manipulating the URL on the client), **hidden input tags** can do the job well. You'll certainly want to encapsulate this, since doing it manually would be a huge pain. Otherwise:
* *If* you're using **ViewState**, you could use that. Otherwise:
* You get the values or an ID (which would be better. see below) into the **URL**. A last resort, because the human will be able to screw this up. Or they might bookmark it and cause confusion when they come back a week later.
**If the values cannot be sent to the client**, then you need to pass a "PageSessionID" or something down to the client. This ID is either a guid (better if security is an issue) or some value you get in a way to guarantee uniqueness. Send to the client in a hidden input tag or in ViewState (or url if no other choice), and store related data on the server based on that ID.

] | As a player, I always take the cautious approach to new player characters - "who are you and what do you want", to see how it pans out. The meta knowledge that this is another member of the story would stop me from actually killing them outright, but a bit of controlled PvP has always been fun.
As a DM however, this can be a bit of an issue. It can cause issues with the players, since the fight is always instigated by one person. E.g. "The rogue kept stealing my gold!", or "I was only pinching one or two gold. He didn't talk to me, he just swung his axe!" These types of fights are always better off handled by talking to the players, rather than resolving it in combat.
If, however, this is plot driven - two PC's forced into combat in an arena, or, perhaps a paranoid PC meeting a new member that has unexpectedly arrived in a hostile environment - perhaps allowing maybe one or two rounds of PvP could be fun; but *only* if both parties are ok with it, and make sure you have a plot device to help stop the battle!
A bigger, common threat is often a good way; the combatants in the arena can use the combat to act as a diversion for the rest of the party to get closer to a target, or the paranoid and the new PC's fighting in the BBEG's Wizard tower are suddenly assailed by the henchmen. *You want to stop the fight before any real damage is done!*

* Make sure that both parties are ok with the PvP
* Make sure you have a plot device to stop it

It sounds fun, and it should happen. Do not let the players get involved. Let them get to a point to where you have to finish the tale via DM narration. In my humble opinion. I've seen this go poorly every single time it's came up.
One example of this went as follows:
I had a large table of 8 players playing 5e D&D. I allowed this large of a group to split into smaller groups to take care of tasks a little more than usual because it was 8 players. Basically I had two groups of 4 most of the time it seemed. They acquired a ship and a crew. 4 had interest in running the ship / 4 decided to just wait that out. The 4 leaders became tyrannical and one of the other 4 wanted to leave the ship. A duel was settled on and I thought it'd be fun to see what the dice said. They took it personally in 1 round.
BUT I can say if I had it to do over I'd let the player's have a chance to choose a Perception.. Or an attack roll.
If they choose attack roll either before a skill check or failing a skill check and not recognizing a target... Let them make an attack roll and just pick a player from the other group for them to shoot against their AC.
Don't let it go to rolls after that tho'. Make that hit or miss the realization of what's unfolding. | If you really want to run a full combat with a chance that the players are legitimately surprised at the end, you'll have to separate them and simultaneously run both ends of the fight.

] | This is where you need adult players who understand meta levels.
Let the **players** know that they are attacking each other, but the **characters** are unaware of it (until they manage perception rolls, etc.)
Also set it up so that the **players** understand this is a fun section that will not harm their characters in the long run. This is successfully done in the LARP field by an even in Germany called Drachenfest, which is pure PvP and has built-in resurrection. So you can play and fight and die a hero and will not lose your character. If the **players** know that this will not be a slaughter, they will probably enjoy it. If they don't, they will pull blows and do all kinds of gamey things to not harm each others characters. | There is two ways you can play this out successfully and it depends on your players which one is the appropriate one:
With good role players, just tell them. They don't recognize each other, so they fight. With good roleplayers, the level of meta gaming should be minimal and a good fight should happen, where everybody is openly playing his character, fighting for his perceived side, against the others, that just happen to be characters as well.
But there are people and groups that are not that good in keeping meta knowledge from influencing their gameplay. This might be a good learning opportunity if you try the above and explain what you expect. But in case this has a low probability of working out because their playstyle is not exactly role playing but more like roll playing, there really is no way to pull it off without physically separating the knowledge. And that means the players.
Separate the two groups when they actually get separated in-game. Put one group in another room. This has the added benefit that for the time you are not with them, they can do stuff without disrupting the gameplay of the respective other group. Whether they discuss gameplay or switch on the gaming console when the DM is out of the room, it's their thing and won't bother the active part of the group.
For the actual combat, you need to have one initiative for the whole group or it will be too tedious. Have one turn play out in the one room, then switch rooms, play the "NPC" turn (repeat what just happend in the room you left) and then let them play their turn. Repeat until they recognize each other and invite one group over into the other room so you are united again, both as players and as characters.
We did this very successfully many times back in school when we had whole weekends to play and having the DM in the other room with half the players was no problem when you could try to beat your fellow players at Tekken for an hour or so. But be aware, this needs both real estate and commitment. Today, with limited time on my hands as an adult, I would maybe not be too happy if I made time for role playing and then had to play console games for half of the evening instead. Make sure you have both another room and the consent of your players when you do this.
Back in school we played 2e, now it's 5e, they are very similar. With other systems that have more "reactions" where your players can make decision even in other peoples combat turns, this might be problematic, but with 5e it should be fine. |

] | Don't let them do it!
It sounds fun, and it should happen. Do not let the players get involved. Let them get to a point to where you have to finish the tale via DM narration. In my humble opinion. I've seen this go poorly every single time it's came up.
One example of this went as follows:
I had a large table of 8 players playing 5e D&D. I allowed this large of a group to split into smaller groups to take care of tasks a little more than usual because it was 8 players. Basically I had two groups of 4 most of the time it seemed. They acquired a ship and a crew. 4 had interest in running the ship / 4 decided to just wait that out. The 4 leaders became tyrannical and one of the other 4 wanted to leave the ship. A duel was settled on and I thought it'd be fun to see what the dice said. They took it personally in 1 round.
BUT I can say if I had it to do over I'd let the player's have a chance to choose a Perception.. Or an attack roll.
If they choose attack roll either before a skill check or failing a skill check and not recognizing a target... Let them make an attack roll and just pick a player from the other group for them to shoot against their AC.
Don't let it go to rolls after that tho'. Make that hit or miss the realization of what's unfolding. | This is where you need adult players who understand meta levels.
Let the **players** know that they are attacking each other, but the **characters** are unaware of it (until they manage perception rolls, etc.)
Also set it up so that the **players** understand this is a fun section that will not harm their characters in the long run. This is successfully done in the LARP field by an even in Germany called Drachenfest, which is pure PvP and has built-in resurrection. So you can play and fight and die a hero and will not lose your character. If the **players** know that this will not be a slaughter, they will probably enjoy it. If they don't, they will pull blows and do all kinds of gamey things to not harm each others characters. |

] | I have witnessed a game where the two stories are played out asynchronously.
Group A was going through their scenario (Took 20-30 minutes?) while Group B waited out their turn (with brief moments of "meanwhile" dialogue to keep them involved). Group A found the group of "bad guys", and managed to launch a sneak attack. After the surprise round, they rolled initiative and then their story paused.
DM then hit the proverbial rewind and we played out Group B's story. They follow their path (with brief moments of "meanwhile" dialogue to keep Group B involved) and eventually get attacked by a group of bandits who get a surprise attack on them.
At this point it was clear that Group A had attacked Group B. Group B relished the opportunity to get a return round. At relevant moments, calls were made for perception checks (before the sneak attack, after the surprise round, when someone got face to face it was with advantage and they realised what had happened)
Everyone seemed to enjoy it. Even though Group B knew out of character after the surprise round that it was Group A that attacked them, they rolled with it.
Alternatively
You could set up an *almost* identical board for each (have a few flourishes or touches to make them seem different) Group A's board showing the positions of Group B as bandits, and vice-versa.

Make the 'bandits/rogues' for each group move in the same initiative order. So you can get a whole round of attacks from a group, then a riposte from the other group. You make the 'rolls' behind your DM screen and fudge them to get the same result as the opposing team did\*.
Once they figure it out you just switch them onto the one board.
Probably harder to pull off, but could really have them fooled if you can do it.

With good role players, just tell them. They don't recognize each other, so they fight. With good roleplayers, the level of meta gaming should be minimal and a good fight should happen, where everybody is openly playing his character, fighting for his perceived side, against the others, that just happen to be characters as well.

Separate the two groups when they actually get separated in-game. Put one group in another room. This has the added benefit that for the time you are not with them, they can do stuff without disrupting the gameplay of the respective other group. Whether they discuss gameplay or switch on the gaming console when the DM is out of the room, it's their thing and won't bother the active part of the group.
For the actual combat, you need to have one initiative for the whole group or it will be too tedious. Have one turn play out in the one room, then switch rooms, play the "NPC" turn (repeat what just happend in the room you left) and then let them play their turn. Repeat until they recognize each other and invite one group over into the other room so you are united again, both as players and as characters.
We did this very successfully many times back in school when we had whole weekends to play and having the DM in the other room with half the players was no problem when you could try to beat your fellow players at Tekken for an hour or so. But be aware, this needs both real estate and commitment. Today, with limited time on my hands as an adult, I would maybe not be too happy if I made time for role playing and then had to play console games for half of the evening instead. Make sure you have both another room and the consent of your players when you do this.
Back in school we played 2e, now it's 5e, they are very similar. With other systems that have more "reactions" where your players can make decision even in other peoples combat turns, this might be problematic, but with 5e it should be fine. |

] | As a player, I always take the cautious approach to new player characters - "who are you and what do you want", to see how it pans out. The meta knowledge that this is another member of the story would stop me from actually killing them outright, but a bit of controlled PvP has always been fun.
As a DM however, this can be a bit of an issue. It can cause issues with the players, since the fight is always instigated by one person. E.g. "The rogue kept stealing my gold!", or "I was only pinching one or two gold. He didn't talk to me, he just swung his axe!" These types of fights are always better off handled by talking to the players, rather than resolving it in combat.
If, however, this is plot driven - two PC's forced into combat in an arena, or, perhaps a paranoid PC meeting a new member that has unexpectedly arrived in a hostile environment - perhaps allowing maybe one or two rounds of PvP could be fun; but *only* if both parties are ok with it, and make sure you have a plot device to help stop the battle!
A bigger, common threat is often a good way; the combatants in the arena can use the combat to act as a diversion for the rest of the party to get closer to a target, or the paranoid and the new PC's fighting in the BBEG's Wizard tower are suddenly assailed by the henchmen. *You want to stop the fight before any real damage is done!*
So, in short:
* Make sure that both parties are ok with the PvP
* Make sure you have a plot device to stop it
* Always stop the fight short - not many people would be happy to see their PC die, and especially not at the hands of a friend. | There is two ways you can play this out successfully and it depends on your players which one is the appropriate one:

6,983 | My 12 year old has been blowing off homework, and now is writing on his clothes!
He plays hockey, which he loves. I stopped letting him play for his teams when his report card came back with bad grades due to his lack of homework.
I told him that if he improved his grades and did his homework by his next progress report (2 weeks) he could play again. He has improved his homework effort but has not done all of it, even knowing that he will not be allowed to play. He pulled up most of his grades, so I allowed him to play again just this week, and then found out he has 10 zero's in math for homework (that was not on the progress report).
On top of that, last night I looked at the sleeve of his $55 Under Armour Sweatshirt and saw that he drew on almost the whole thing with a sharpie marker.
Am I losing my mind or is he regressing to a toddler? Nothing works as a punishment for this kid. He has lost Xbox, his TV, his phone, hockey etc. Nothing phases him. He cares for a moment then seems to have the whatever attitude. Not sure what to do. | 2012/12/19 | [

] | This sounds like fairly common behavior for a boy that age.
In fact, it sounds an awful lot like me at around 13-14.
It may just be that he is testing boundaries, or it may be that he genuinely has an issue with doing his homework.
The first step I'd suggest is finding out *why* he hasn't been doing his homework. Is he bored? Is it too tough? Does he feel he doesn't have enough time to do it? Or does he just "not feel like it"?
Try to work to alleviate his reasons.
If it is too tough, talk about what options he has (tutoring, talking with the teacher, switching class tracks if necessary/possible, etc.).
If he doesn't have time, work with him to create a schedule for his week. This will help identify what activities may be taking up too much of his time, and help teach him some valuable time management skills.
If he's bored, you can look at ways at supplementing the assignments, either by working with the teacher, establishing your own criteria (i.e. add a research paper on some aspect of the topic that your son finds interesting), or looking for outside resources. [This answer from another question](https://parenting.stackexchange.com/a/210/420) provides some good advice.
However, finding out why he isn't doing the homework is only the first step.
You should absolutely keep up with the restrictions you've already put in place (loss of hockey privileges, other recreation, etc.) until he shows an appropriate level of improvement.
It sounds like he's shown *some* improvement, and you shouldn't underestimate that. You don't indicate whether the 10 zeros in math were from before or after you reinstated hockey privileges, but if they were from before, I'd consider letting him play unless he misses more assignments after he starts back up. It would be a bit harsh and discouraging to earn back his privileges by putting effort into doing better (which it sounds like he has), only to lose it because of old mistakes catching up to him.
Most importantly, I suggest setting concrete guidelines for what is required from him in order to regain each privilege he lost. Its too vague to say something like "when your grades get better", or even "when you stop missing your assignments".
Be very concrete. Set rules such as "if you complete 100% of your assignments for all classes for the next two weeks, you can start playing hockey again. After that, if you miss more than one assignment in a week for any given class, you'll lose it again."
If there are certain classes he's struggling with, you may set goals/rules that account for that. Perhaps he gets some leniency in the classes he's doing well in, provided he puts extra effort into the classes he's having a hard time with.
You also want to make sure you communicate clearly and frequently with him. Be proactive. Ask what his assignments are. Talk to him about what times he plans on working on his assignment, and respect those times (perhaps bring him a snack while he's working to show support).
As for drawing on his clothes, well... I wouldn't read too much into it. I remember that lots of kids in my school drew on their clothes, myself included. All I suggest doing is be very strict in that you won't buy him new clothes just because he decided that he didn't like how the drawings turned out. Being short on clothes, or forced to wear something that has been "decorated" in a way that he no longer likes, will drive home that lesson pretty quickly. Of course, if he legitimately outgrows the clothes, then they can be replaced as normal. | I might want to add: *Have you sat down down in calm way. How is school?*
Get to know him. He might shrug you off right now but I remember my parents never talking to me and can be strict which made us rebel more. Taking hockey away I understand but that is the only place that may help to cool off and help with stress.
Maybe you might want to art project with him on his shirts. I think he's expressing himself though bored. My daughter has ADHD. Maybe he has problem and maybe you over looked. You are doing great as parent but sometimes we don't listen and we just get angry and lash out instead of listening. I've been having one on one with my kids for over a year now and one my boys would never tell me how he feels unless we are alone.
My kids lie a lot but they are changing because I set rules and what will happen. Someone once asked about how i parent my kids too when it came to every little think. I was punishing for tiny things that shouldn't matter as much as encouraging my kids to be the best they can be.
I've been learning through my teen that I need to say more positive things instead always saying. why can you this? why didn't she follow through on washing her clothes. I learned we adults want them to be doing it now when they will learn but not at our pace. I know when my boys reach to teen it won't be easy with their disabilities. When was young I tried to run away as teen several times. Punishing wasn't the answer. I wish my parents asked me why? I wish they put their arms around me when I was calm. |
6,983 | My 12 year old has been blowing off homework, and now is writing on his clothes!
He plays hockey, which he loves. I stopped letting him play for his teams when his report card came back with bad grades due to his lack of homework.
I told him that if he improved his grades and did his homework by his next progress report (2 weeks) he could play again. He has improved his homework effort but has not done all of it, even knowing that he will not be allowed to play. He pulled up most of his grades, so I allowed him to play again just this week, and then found out he has 10 zero's in math for homework (that was not on the progress report).
On top of that, last night I looked at the sleeve of his $55 Under Armour Sweatshirt and saw that he drew on almost the whole thing with a sharpie marker.
Am I losing my mind or is he regressing to a toddler? Nothing works as a punishment for this kid. He has lost Xbox, his TV, his phone, hockey etc. Nothing phases him. He cares for a moment then seems to have the whatever attitude. Not sure what to do. | 2012/12/19 | [

] | This sounds like fairly common behavior for a boy that age.
In fact, it sounds an awful lot like me at around 13-14.
It may just be that he is testing boundaries, or it may be that he genuinely has an issue with doing his homework.
The first step I'd suggest is finding out *why* he hasn't been doing his homework. Is he bored? Is it too tough? Does he feel he doesn't have enough time to do it? Or does he just "not feel like it"?
Try to work to alleviate his reasons.
If it is too tough, talk about what options he has (tutoring, talking with the teacher, switching class tracks if necessary/possible, etc.).
If he doesn't have time, work with him to create a schedule for his week. This will help identify what activities may be taking up too much of his time, and help teach him some valuable time management skills.
If he's bored, you can look at ways at supplementing the assignments, either by working with the teacher, establishing your own criteria (i.e. add a research paper on some aspect of the topic that your son finds interesting), or looking for outside resources. [This answer from another question](https://parenting.stackexchange.com/a/210/420) provides some good advice.
However, finding out why he isn't doing the homework is only the first step.
You should absolutely keep up with the restrictions you've already put in place (loss of hockey privileges, other recreation, etc.) until he shows an appropriate level of improvement.
It sounds like he's shown *some* improvement, and you shouldn't underestimate that. You don't indicate whether the 10 zeros in math were from before or after you reinstated hockey privileges, but if they were from before, I'd consider letting him play unless he misses more assignments after he starts back up. It would be a bit harsh and discouraging to earn back his privileges by putting effort into doing better (which it sounds like he has), only to lose it because of old mistakes catching up to him.
Most importantly, I suggest setting concrete guidelines for what is required from him in order to regain each privilege he lost. Its too vague to say something like "when your grades get better", or even "when you stop missing your assignments".
Be very concrete. Set rules such as "if you complete 100% of your assignments for all classes for the next two weeks, you can start playing hockey again. After that, if you miss more than one assignment in a week for any given class, you'll lose it again."
If there are certain classes he's struggling with, you may set goals/rules that account for that. Perhaps he gets some leniency in the classes he's doing well in, provided he puts extra effort into the classes he's having a hard time with.
You also want to make sure you communicate clearly and frequently with him. Be proactive. Ask what his assignments are. Talk to him about what times he plans on working on his assignment, and respect those times (perhaps bring him a snack while he's working to show support).
As for drawing on his clothes, well... I wouldn't read too much into it. I remember that lots of kids in my school drew on their clothes, myself included. All I suggest doing is be very strict in that you won't buy him new clothes just because he decided that he didn't like how the drawings turned out. Being short on clothes, or forced to wear something that has been "decorated" in a way that he no longer likes, will drive home that lesson pretty quickly. Of course, if he legitimately outgrows the clothes, then they can be replaced as normal. | I disagree with removing hockey. Why? I remember being in the exact same situation and how it affected me as a person.
When I was that age, I had one thing: music. It was my *passion*. At 13 I was writing Manilow-like music (it was 1978) on our horrible piano and I was playing trumpet and french horn at school.
Meantime, my grades in Civics, Math, etc, suffered. The next thing I know, the piano is locked down and I'm being held out of orchestra at the local stock theater "until your grades come up."
The result was not motivation, it was **hate**. I'm 48 years old now and you see how I describe it. Lasting impression? A little. As a 13 yr old, all I saw was my parents using that thing I love against me for. . . whatever. So what if it was for my own good. It doesn't change the fact that it pissed me off and irrevocably changed my relationship with my parents. That's what they call 'collateral damage'. And baggage. It's like luggage cuz they carry it around forever.
Of course that is not what they intended, but it's how a 13yo can see it in their closed off 13 yr old world and it's the lasting impression when parents forget having been 13. It's a mixed up world with everything changing and societal norms going against biological evolution. Did you know that no other mammal enforces a familial relationship with offspring beyond their ability to reproduce? So not only does family seem "different", but friends are different, school is different, the world is smaller and everyone's expectations are different. The 13 yo expects to be able to make their own decisions, thanks to biology, but parents still want to tell them to "take a shower", thanks to the nuclear family.
Today, as a parent of 5, I understand what my parents goal was when telling me I couldn't be musical, but I absolutely disagree with the method.
My idea? Instead of negative reinforcement, try positive reinforcement. Instead of the police state "No. Not until X", I'm suggesting that you come at it from the other side. Good grades? New stick. Or gloves. Or whatever. If you're like me, you can see their grades online. With an immediate term gain, go back to hockey AND do something different/special.
>
> "You know why we went out to dinner after hockey practice? Your grades. Nice job and keep it up. There's more where *this* came from, if there's more where *that* came from."
>

It is respecting that thing they love and allowing them to get closer to it. [It's similar to what I'm doing now with my 12 yo and have had a modicum of success.](https://parenting.stackexchange.com/questions/8984/how-to-restrain-my-13-year-old-pubescent-sister/9023#9023) I'll even bet that I've had no more success than you, but I can guarantee that my daughter isn't pissed off about it.
Last thing: It's easy to say "Yeah? They just need to get over it. this is the way it's gonna be." Those words can fall out of a parents mouth easier than the corner of a chip (crisp for you euros). Don't forget how it felt when your parents said that to you. |

I would set aside time with him specifically for working on homework, and help him with it.
The best learning most often happens at home. In this case, you're not only helping him learn his school material, but you're teaching him that the things that are important *for* him are important *to* you.
I really believe he needs help, outside of school, from either you, the other parent, or some sort of tutor. If he really enjoys hockey, but even that's not enough of a motivator for him, then he may be blowing off homework because he feels something like, "I'm never going to get it anyway", and gives up from hopelessness. He needs assistance in learning how to overcome this obstacle, learning that difficulties like this can be overcome, and that being a hard worker is the most valuable trait he can have.
When you feel hopeless about something, punishments won't have any other affect than increasing that hopelessness. As the pressure to perform continues to build with each new punishment, the ability to perceive a way through continues to degrade.
If your son isn't finding the assignments difficult, but rather too easy (and thus a waste of time), then time should still be set aside to work with him. This could easily become a time to praise him for his work (and also reward him.) |

] | **Couple** is a collective noun. It takes a singular form and refers to two people.
So, *one couple* comprises *two people* and *two couples* comprise *four people*.
In a sentence, the subject-verb agreement follows the singularity or plurality of the word **couple** itself—not the people who compose it.
So, there are two ways of expressing your example sentence:
>
> 1. Both *couples work* at the same bank.
> 2. Each *couple works* at the same bank.
>
>
>
---
**Update**: Based on a comment, the sentence may also be talking about one of the individuals within a couple.
Let's say that Bob and Mary form a couple, and Emma and Mike form another couple. Bob and Emma both work at the same bank.
If we know their names:
>
> Bob and Emma work at the same bank.
>
>
>
Otherwise, we could say:
>
> 1. Each couple has a member who works at the same bank.
> 2. Both couples have a member who works at the same bank.
> 3. From among each couple, there is an individual who works at the bank.
>
>
>
If you are talking about families in which couples work:
>
> 1. In our family, both of us work.

With a *single* couple, you can't refer to *both* couples working because there is only one couple. You have to refer to individuals or members, or use some other term that singles out one of the people in the couple from the other. (If you know the couple, use a name.)

Of course, if you are actually referring to a single couple as a collective whole, then the other answer gave a common way of doing so (although there may be a difference between common US and UK English when it comes to subject-verb agreement with collective nouns):

There is no need to say *at the* ***same*** *bank* because the couple as a whole is treated as a single unit; each member does the same thing when referenced in this way. | Neither. It would be "The couple...". You can't use couple to refer to two people in a relationship separately, the noun [couple](https://www.etymonline.com/word/couple) originates from the Latin word 'copula' which means "link" or "tie" that connects 2 things together. So you can't say both couples (unless you mean 2 different couples), but *both persons* if you want to specify 2 separate individuals that work at a bank but aren't necessarily connected to each other:
>
> Both persons work at the same bank
>
>
>
It is not:
>
> \*Both person work at the same bank
>
>
>
However, you can say:
>
> A couple work at the same bank
>
>

or

> The couple work at the same bank

I use and distribute my authorized\_key file to multiple computers, limiting my access so only my primary home is allowed to login to other accounts.

It becomes especially important when shared homes are used (as they generally are on a cluster).
It is a real shame it is now depreciated.

*[The Case for Mars](https://books.google.com/books?id=NC8XZEddojsC&dq=%E2%80%9CThe%20case%20for%20mars%E2%80%9D%20gaslight&source=gbs_navlinks_s): The Plan to Settle the Red Planet and Why We Must*, by Robert Zubrin, published by Simon and Schuster, 2012.
In it Zubrin describes the steps needed for human habitation on Mars, starting with the first and most critical step: manufacturing propellant for liftoff and return for the first visitors (because carrying enough fuel for the return trip from Earth is prohibitively expensive to lift out of Earth’s gravity well).
Here, he says:
[](https://i.stack.imgur.com/V9cJy.jpg)
>
> In 1976, Professor Robert Ash, now of Old Dominion University, and some JPL collaborators published a paper laying out some *simple, robust and well established* (**Gaslight era**, to be precise) chemical engineering processes...
>
>
>
So I think what you’re looking for is:
### *Gaslight era*
But I want to offer a caveat here: this is *not* a standard or generic term for *any* proven technology.
Instead, he’s saying for this specific purpose — manufacturing propellant *in situ* — the techniques developed and perfected during the 19th century by the first wave of “modern” scientists who discovered chemistry, would be sufficient for the purpose.
The goal of the book is to make a clear case that Mars can be settled in a practical and realistic way. Part of that is recognizing that some of the most critical processes don’t require “future tech”, or even high tech, and can be done on a [reasonable] budget.
In other words, the argument behind the phase in this context is:
*The same fuel that those pioneers created processes to efficiently and effectively manufacture from simple ingredients, sufficient to move the world from candlelight to gaslight, to illuminate this world, in a sense, is also fuel sufficient to get our astronauts home from another world altogether.* | >
> **[Tried and tested](https://en.oxforddictionaries.com/definition/tried_and_tested_(or_tried_and_trusted))**
>
>
> Denoting something that has proven in the past to be effective or
> reliable

This seems the most apt phrase to use in this situation. (Three words not two, but then one is a conjunction.) |
