] | I'm not an expert re: PPM communications but, from what I can tell, PPM signals contain pulses which are interpreted by the receiving microprocessor (or speed controller) as position commands. If the pulse is the smallest acceptable width, then the position of the servo will be commanded to go completely to one side; if the pulse is the largest acceptable width, then the position of the servo will be commanded to go completely to the other side. The PPM pulse is essentially a position setpoint, and the control of the power to achieve this position is up to the device that receives this signal.
On the other hand, a PWM signal will often directly regulate the amount of power that is transmitted to the motor. Consider the per cent that the PWM is ON - if it is ON 100% of the time, the motor will receive the highest possible amount of power. If the PWM signal is on at a 50% duty cycle, the motor will receive 50% of the available power.
Essentially a PWM signal is part of a lower-level control loop, as compared to the PPM signal. With the PPM signal, the speed controller takes care of the lower loops for you. | In Radio Control lingo, we refer to PWM (Pulse Width Modulation) to describe a very specific **control** signal, instead of a power signal. Check the [wiki article](https://en.wikipedia.org/wiki/Servo_control#Pulse_duration) for more info. This doesn't carry the power required to drive the servo, but encodes angle information for the servo to obey.
In order to enclose PWM setpoint information (for more than one servo) in the same wire, we use a PPM signal (Pulse Position Modulation). Essentially, this is multiple PWMs, each one shifted in time a bit, and interleaved.
More info [here](http://rcarduino.blogspot.gr/2012/11/how-to-read-rc-receiver-ppm-stream.html).
In your case, sadly the repo author has made a mistake, and he meant to say **PMW** ESC, instead of CAN-bus, etc.
Luckily, the arduino boards can drive RC PWM devices using the *servo* library. |

] | I believe there is confusion about these terms. Strictly speaking, the ESC is PWM controlled. Although the signal usually gets there from a transmitter and receiver signal that is PPM encoded.
It seems to me, that many sources will have you believe that PPM is just a multiplexed PWM like this:
[](https://i.stack.imgur.com/rNJLl.jpg)
[](https://i.stack.imgur.com/8ezPY.jpg)
But in reality it is actually more like this:
[](https://i.stack.imgur.com/J4ycX.jpg)
Note in the final diagram that the actual PPM signal does not vary significantly in pulse width, only it's position is significant. Hence the term *Pulse Position Modulation*. From those positions, a controller will reconstruct a PWM signal that resembles what appears in the "Partial PPM Pulse" diagram (and is unfortunately labelled as PPM). That "PPM" signal (actually a multiplexed PWM signal) now has widths that are significant.
Rather unfortunately, neither that true PPM signal nor the so called PPM (actually multiplexed PWM) signal will make your ESC work correctly. It also has to be demultiplexed so that the information for only a *single channel* is fed to the ESC (or servo). This is in fact a PWM signal again.
It might be because the PWM has to have specific dimensions to work on the ESC that they don't want to use the term PWM, in other words its not just any generic PWM signal. Specifically the pulse width usually needs to be 1500µs long (+/- ~500µs) and occurs 20000µs apart (hence the 50Hz frequency), but there are alternatives to that scheme. Compare this to a PWM signal that can be used to control the brightness of an LED, for example, which can have any frequency and the widths can vary between 0% and 100% of the duty cycle. These are vastly different requirements from the PWM signal required to operate the ESC.
As far as I am aware, most ESCs used in RCs will have this type of control schema.
**So in conclusion:**
PPM when used to refer to ESCs is meant to be a specific kind of PWM. Any ESC that says it is PPM or PWM compatible is referring to the same thing. An alternative would be a serial motor controller, but I have never heard of one that was referred to as an ESC. Those are simply "motor controllers". For example, [these ones](https://www.pololu.com/search?%5Bsearch_type%5D=&query=motor%20controller&x=4&y=7). Also not that some of the controllers on that page are also PWM controlled, *but it is not the same kind of PWM -- more akin to the LED brightness control I mentioned above.* | In Radio Control lingo, we refer to PWM (Pulse Width Modulation) to describe a very specific **control** signal, instead of a power signal.

88,044 | I've been cooking a 6.5 lb. whole chicken tonight and I'm confused by the temperature readings. After about an hour and a quarter, the thickest part of the thigh is at 175 degrees but the breast is only at 140. From reading around, it sounds like the breast normally cooks faster than the thigh. So I'm confused. Most articles state to measure the temperature at the thickest part of the thigh. Do I also need to be concerned about the breast temperature? Why could there be such a variance?

] | You are probably touching the bone with the probe tip | Well it depends how you cook the chicken. Depending if you are going to Rotisserie or not will depend how you should prepare the chicken. If you are going to cook it in an oven or smoker then you want to fly the chicken. This involved cutting the spine out, breaking the center rib and flattening it out. When you don't fly the chicken and place it in an oven then the thighs are lower to the pan that tends to create additional heat as apposed to the breast that is higher. Since breast meat takes longer to cook the lower you can get it the better.
**Rotisserie**
If you decide to rotisserie it then there is no need to fly the chicken since it gets a pretty even cook all the way around
**Oven/Smoker**
If you are going to make it in an oven or basically anything else then you need to fly it. Here is a [video](https://www.youtube.com/watch?v=tKsOPkn7XTM&t=838s) to learn how to do that. Great video from some smoker guys that give a good explanation.

] | A miss when under load could be anywhere in the ignition system. Start with new plugs and wires (as these are cheap, and you may be able to change them yourself), and if this does not resolve the issue, move on to the coil packs or distributor and coil (depending on how your car is equipped).
Coil packs are expensive, so there is a way to isolate a specific coil pack if you can hear the miss at idle. Simply pull one plug wire at a time and run the engine. The engine will run rough, but if the miss is still present, you know that the cylinder for which you pulled the coil pack is not faulty. When you pull a plug wire and the miss is gone (the engine does not run much worse), then you have found the faulty coil pack.
**Clarity** If you can hear the miss at idle, it's missing with all plug wires connected. Pulling a good plug wire should cause a 2nd miss (and rougher running). Pulling the bad wire should cause no change (still missing just like with 1 wire connected). The miss will certainly not "go away" with a spark plug wire disconnected. | I wouldn't be too concerned about the belt squeal. Generally the serpentine belt is not toothed and cold components are going to have more friction that warm components. It could be an early sign that an alternator, ac compressor, etc is going to go, but it's probably just a sign that it's cold. Cold weather can also cause condensation on the belts which can facilitate some initial slippage. When the squeal is more consistent or occurs with the engine running other than shortly after starting, it's time to have the belts looked at.
Unless the car is under warranty, the ignition system problem is what I'd be looking at/spending money on, not some minor belt squeal. Though if you take the car in for something else (oil change, the ignition problem) you could ask have the belts/pulleys checked for wear. |

If it's not really there when idling, but squeals quite loudly when you rev up, it's probably the accessories drive belt a little loose. What's happening is that the alternator is taking quite a load to replace the battery charge. If the squeal is more or less constant, it could be the water pump (if not driven by the cam belt) or alternator bearings on the way out. Have a shufti at the water pump to check for slow leaks. |

39,838 | Halo!
We are in the midst of our honeymoon, and are traveling from Amsterdam to Brugges to Paris. Upon our first breakfast in Amsterdam we were presented with small (about 1.5 to 2 inches in length, about .75 inches in diameter) sausages. They were a regular breakfast item in Amsterdam, and then again in Brugges.
They are very light in both color and flavor. If I had to guess, they contain a mixture of chicken meat and pork fat. The contents are definitely emulsified. They are in natural casings, or at least they certainly were in Amsterdam. As I said, they are served with breakfast. In Amsterdam the sausages were very dense so the casi g would brown and pop open, whereas in Brugges the casing was much less full, which provided a pillowy, soft texture.
Does anyone know what these sausages are called? I'd love to make them for myself when I get back to the US. | 2013/11/28 | [

You might consider Service Broker messages in some scenarios; the details depend on your app.
In most cases, you can probably use SqlDependency or SqlCacheDependency. The way they work is that you include a SqlDependency object with your query when you issue it. The query can be a single SELECT or a complex group of commands in a stored procedure.
Sometime later, if another web server or user or web page makes a change to the DB that might cause the results of the previous query to change, then SQL Server will send a notification to all servers that have registered SqlDependency objects.

Although you need to enable Service Broker to use SqlDependency, you don't need to interact with it explicitly. However, you can also use it as an alternative mechanism; think of it more as a persistent messaging system that guarantees message order and once-only delivery.

] | Notification Services was deprecated, but you don't want to use that anyway.
You might consider Service Broker messages in some scenarios; the details depend on your app.
In most cases, you can probably use SqlDependency or SqlCacheDependency. The way they work is that you include a SqlDependency object with your query when you issue it. The query can be a single SELECT or a complex group of commands in a stored procedure.
Sometime later, if another web server or user or web page makes a change to the DB that might cause the results of the previous query to change, then SQL Server will send a notification to all servers that have registered SqlDependency objects. You can either register code to run when those events arrive, or the event can simply clear an entry in the Cache.
Although you need to enable Service Broker to use SqlDependency, you don't need to interact with it explicitly. However, you can also use it as an alternative mechanism; think of it more as a persistent messaging system that guarantees message order and once-only delivery.
The details of how to use these systems are a bit long for a forum post. You can either Google for them, or I also provide examples in my book ([Ultra-Fast ASP.NET](https://rads.stackoverflow.com/amzn/click/com/1430223839)). | You can use the System.Data.SqlClient.SqlDependency (which works with Service Broker on) to subscribe to changes in a table. |

I'm pretty sure this sentence is incorrect because the conditional clause has its pronoun omitted, and I couldn't find any rule such an omission would be justified by. I believe "you're" cannot be omitted without rephrasing the sentence.
My acquaintance argued this omission is acceptable in technical documentation and often used as a sort of "shortcut". He wasn't able to provide any links to dictionaries that would support his claim, I never saw such use described as acceptable, and I am not convinced by his word alone.

Well, if you know the opening lines well enough it really makes no difference what the time control is, as in any case the first 10-15 moves are (somehow) forced. This said, the standard main-main line (Mar de la Plata variation) for White against the King's Indian is indeed an attack against Black's Queen side (especially against c5 or by playing Be3-Nb5 pointing at a7) where White tries to move the focus elsewhere to counterattack what Black is carrying out on the King's side: in this respect the plan is conceptually easy, in the sense that especially in a blitz game you already know where your pieces go and what they must attack without having to actually think of a plan.
However:

the Smyslov line is indeed one way to play it without all the hassle that the main line involves: White tries to make ...e5 somewhat more difficult (by pinning the f6 Knight) and to avoid the standard maneuver Ne8-f5 (as the Knight is pinned on the Queen). As such, Black usually tries to un-pin with h6-g5 and in that case it is White to start carrying an attack on the King's side against the prematurely exposed g-h pawns of Black's; the play anyway is to be studied line by line (do not take the above as a general recipe).
Another attempt may be the Panno variation (fianchetto variation), where the structure g3-Bg2 makes it more difficult for Black to break open the King's side checkmating the White King very fast. There is a didactic video [here](https://www.youtube.com/watch?v=QSAVnq40JdY&t) that may give you a taste thereof (but there is a lot of free GM content elsewhere too). | I merely depends on what kind of a blitz player you are.

There *is* a lot of theory in these variations, but it is more dispendable than in the main lines. Thanks to your kingside fianchetto you are not in danger of a direct kingside attack, so it is much easier to naviguate with general concepts (fight for the center!) and without specific knowledge. |

] | Yes, in **some cases** it is countable, example from [Oxford Dictionary Online](https://en.oxforddictionaries.com/definition/potential):
>
> [count noun] ‘the potentials of the technology were never wholly controllable’
>
>
>
Also as a quantity (for example in physics or maths) it can be countable, example from [Oxford Dictionary Online](https://en.oxforddictionaries.com/definition/potential):
>
> ‘Electrical action potentials, osmotic perturbations or chemical signals may trigger these waves.’
>
>

In mathematics (or science in general) you could say **scalar potentials** to refer to more than one **scalar potential**. An example of this can be found [here (lecture notes from the School of Physics and Astronomy of the University of Edinburgh)](https://www2.ph.ed.ac.uk/~rhorsley/SII08-09_mp2a/lec22_2.pdf).
Attribution: "Potential | Definition of Potential in English by Oxford Dictionaries." Oxford Dictionaries | English. Accessed April 03, 2018. <https://en.oxforddictionaries.com/definition/potential>.
In **your case**, however, I would refer to this example from [Oxford Dictionary Online](https://en.oxforddictionaries.com/definition/potential) and recommend the singular version in your sentence because you refer to the potential of the audience as a whole:
>
> ‘You could say that we can compare our capabilities and potential to that of an iceberg!’
>
>
>
So in your sentence that would be (without the **s**):
>
> The teachings are dispensed according to the audience's potential
>
>
> | The original sample line (or at least 2 out of 3):
>
> The teachings are dispensed according to the audience's potentials
>
>
>
The question appears to hinge on whether this would better stated as:
>
> The teachings are dispensed according to the audience's potential
>
>
>
These mean two different things.
In the first case the implication is that the "teachings" are "personalized" for each audience member, based on his/her "potential".
In the second case the implication is that the "teachings" will be somehow adjusted based on an overall analysis of the "potential" of the audience as a whole.
Looking at the other sample line:
>
> The teachings are dispensed according to the audience's levels of
> potential?
>
>
>
This is just a slightly more awkward to say "... audience's potentials". |

If homework questions are boring, solutions include:
* not reading questions tagged [homework]. The current software makes this easy (though it filters out advanced homework questions which are often more interesting).
* having tags for the objective features that make homework (and many non-homework) posts boring. e.g., the question is a [task] phrased in the [imperative]; it is [numerical]; it requires a [specified-method]; it demands attainment of a [specific-objective] rather than information on how to get from somewhere-near-A to somewhere-near-B. (The last item could be another definition of a "task").
* handling volume growth by adding sites for existing popular categories of material including algebra, calculus, probability, topology, logic, mathematical competitions/problemsolving, number theory, *and math-homework*. Statistics and theoretical computer science are up and running. Specialization would, among other benefits, promote a higher number and quality of non-homework postings.
* adding more rating dimensions to capture and filter (in- or exclusively) features of homework more specific than "someone didn't like something about the question". | How about not giving reputation points for answering or asking questions tagged [homework]? (Kind of like Wiki.) |

One reason could be that they are biding their time to wait for a long winter, magic to return, or their forces to build up.
The other reason could be that they just don't know about the gap. They seem to have been "dormant" for millennia, and the Wall was built after their defeat. Who's to say that they have travelled as south and tested the defences?
The other thing we don't know much about is the magical ward placed on the Wall. Is it tied specifically to the physical structure of the Wall, or a general line from the eastern coast to the western coast. Like would an Other get stopped against dead space when they try to walk past the gap?

The wight are semi-mindless attackers but they essentially can go anywhere in the world and are only stopped by fire.
The Others including the king need the night and perhaps the cold as a source of power. They wait until the long night (winter) to cross the wall and become dominant south of the wall. The wall has magic that stops them but you are right in thinking they can just cross the water in boats which is probably what they do.

] | As of *Game of Thrones* Season 7 Episode 6, "Beyond the Wall", it would appear that the wights are not the best in water. I'm still not entirely convinced if they can swim or not (see: chains and grabbing Tormund's legs), however, they do fall into the water and seem to sink so it would point out that they aren't the best in water. See the following video (starts at 1:09 in case the link doesn't work).
The wights also then wait it out until they know that the lake has frozen over once again. This isn't conclusive proof that they can't swim because there could be a number of other reasons why they'd wait. For example, minimise losses, they're in a worse position coming out of the water, why attack when they have no chance of escape etc.
The evidence from this episode, along with Hardhome as mentioned in the OP, would seem to suggest that the wights at least can't swim.
The White Walkers are, however, a different thing altogether and it hasn't been shown one way or another if they can swim or even freeze water. They can do things with ice we wouldn't believe, see their swords and spears.

1. Select, then Copy, and Paste in Place one of the objects which you want to use to cut out the other.
2. Then set the stroke to black, and make the stroke thicker.
3. Send it behind the object using *Object > Arrange > Send backwards*. And then group both these objects together.
Wherever you move the grouped objects, the thicker stroke will automatically hide what's below.
For example:
[](https://i.stack.imgur.com/aYM4G.gif)
When I double click the grouped object above, and enter isolation mode, you can see how it's constructed. The thicker black stroke outline becomes visible.
Also here is a slightly more little more complex method. This is ideal if you want to do the same over another background image such as a wall. You can use the same outline to create a mask.
For example:
[](https://i.stack.imgur.com/xDeyE.png)

] | Firstly, even if You were to populate an entire garden with plants that never produce flowers, it still wouldn't prevent yellow-jackets, wasps or hornets from flying in and possibly building their nests nearby because nectar isn't the only food source for them. You see, come spring all the way through summer, wasps need protein to support the hive and the queen and that protein comes in the form of other insects and pests that are present in almost every garden. Come autumn, they shift their attention to sugar for the winter and in doing so through out the growing season, they help pollinate plants and get rid of harmful insects. So see them as pest eaters for that's what they really are. What you can do, however, is minimise the number of these annoying stingers by making sure your garden isn’t a wasp magnet or in your case, choosing the right climber and caring for it correctly. If your willing to compromise on flowers, then choose a fruitless grapevine that is of course attended to for pest infestations. However if flowering is a must then choose a climbing rose. There are a few things wasps are particularly not fond of. Red flowers (wasps aren’t attracted to warm red colours). Marigolds (many insects don’t like the smell). Closed and double-flowered plants such as roses (too hard to access). Flowers that don’t produce much nectar such as Geraniums. Flowers that bloom before wasp season. So from the list, red colour + roses and you get a climbing rose that would probably work best given the criteria.
UPDATE
The OP has found a paper that discusses pollinator flower color preferences and has asked that it be added to this answer. The paper, titled "[Pollinators show flower colour preferences but flowers with similar colours do not attract similar pollinators](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4970366/)" is from the National Institutes of Health, National Library of Medicine and was published in 2016. | If you want a plant that bees don't bother to visit, buy something that has double flowers - these are often sterile and don't produce pollen, so they're no use to bees. As for deer resistant, that's another matter altogether; Trumpet Vine and Wisteria are not terribly attractive to deer, but they are both attractive to bees. Finding something that fulfils both objectives is, I fear, going to be impossible... If you decide on a rose (even though they're not necessarily deer resistant) choose one that has flowers with as many petals as possible - for instance, the climbing variety 'James Galway' (<https://www.gardenia.net/plant/rose-james-galway-auscrystal>) is densely petalled and that makes it much harder for bees to access any pollen, and therefore less attractive to them. Check the height and spread of any rose before buying though, to make sure it has the appropriate height and spread for your purposes. |

] | The problem you're running into is that \Application Data is an NTFS junction point to \AppData\Roaming. Microsoft changed the \Application Data directory's path when Vista came out. The junction point was provided for compatibility purposes.
When you extract the archive, completely exclude the Application Data directory and you should be fine. If, after you've extracted the archive, you find that some programs don't work, you can recreate the \Application Data link by using the `MKLINK` command.
The reason it got this way in the first place is that Windows has had historically poor support for symlinks -- something which \*nix-based operating systems have had for decades. Even though NTFS supported them since Windows 2000, they were never used until Vista came out, and this explains why Explorer is not handling them properly when 7-Zip extracts the archive.
As the old joke goes, Microsoft doesn't know how to spell SYMLIN~1.lnk | If your system is running out of disk space, delete the old parent copy after extracting the next child copy. 7-zip has command-line functionality to help you automate this in a batch script if it makes things easier for you.
The system may not actually be running out of disk space, but the pathname contained inside the zip may be too long. I would also check **My Computer** to see how much space is left on your disk when you get these errors. |
6,815,831 | I have made two targets in my project. One for a Staging version and one for a Release version. This way I control the different setting that goes into each build.
(different version, different identifier, different URL schemes etc.)
Everything in the (with the appropriate target selected) "Build Settings" tab behaves nicely and does not change. The things in the "Summary" and "Info" tabs, however does not persist between building/running the app.
If I go to the Staging Target and enter a version number, then to the Release Target and enter a different number everything is fine at first. When I Run the project, however, the values gets "synchronized". So if I run the Scheme that uses the Release Target it will set Release Target values on the Staging and vice versa.
In my understanding the targets inherits their values from the Project Settings, but I am pretty sure they should not inherit from each other, which would defy the point of targets.

The solution is to make an individual info.plist file for each target.
I now have app-info-staging.plist and app-info-release.plist - each with the values specific for the target.

Good luck! | Your question is quite open ended, but I assume what you are after would be some sort of routing engine.
GeoServer and OpenLayers do not have routing capabilities built in (someone can correct me if I am wrong though), so you would need some sort of routing engine on your server such as [RouteWare](http://www.routeware.dk/rwnetserver/rwnetserver.php "Routeware Net Webpage"), or you could use a web routing service such as the [Google Directions API](https://developers.google.com/maps/documentation/directions/ "Google Directions API").

] | The most improvement with the least effort will come from adding rapid random restarts to your solver. DPLL is known to exhibit heavy-tailed behavior, producing both short and long search times for instances depending on initial search conditions. Random restarts allow the solver to bail out of exponentially long searches of unfruitful assignments and give the solver more chances to find one of those short searches sooner.
Implementing two-watched-literals will produce the next big improvement because it eliminates a major backtracking cost. Backtracking is done exponentially often in the worst case, so any improvements there offer unequivocal improvements in search speed. Implementing two-watched-literals will require a significant overhaul of your solver, but it will teach you a lot about how real-world SAT solvers work. | I suggest to implement CDCL with
1-UIP (UIP = unique implication point) as heuristic to minimise the learned clause. Use 2WL to speed up unit-propagation. See [here](https://bitbucket.org/lorensi/pysat) for a basic implementation of CDCL in Python.
Things like VSIDS make sense only for CDCL, and are used to prune learned clauses. CDCL has a tendency to learn too much. But if you have only approx. 1.5k clauses, you should probably be able to live without pruning, |
26,978 | *Long back story below. See last paragraph for question.*
My cat just turned 9 months old. I’ve researched and it was recommended that you free fee a kitten till 1yr old, for growth.
She was abandoned with a sister at 2weeks. I don’t know how much colostrum or milk she got from her mother. The lady who found her bottle fed her and had her on adult wet food when she told me I had to come get her if I wanted her at 5weeks.
I intended that she be mostly on wet food and did my research. I chose Wellness Complete Kitten Wet Food. I thought the dry food would be a small portion of her diet and didn’t research. Our vet had recommended Royal Canin S/O for our old cat for his urinary tract issues, so I assumed it’d be okay for a supplementary feed to giver her something to eat when I was at work. I wasn’t at home to do the recommended multiple small meals a day.
She got to where she liked the dry food better than the wet. I’d come hone and there would be wet food left and her dry would be empty. Since it was a larger part of her diet, I looked into it and found out their food, at least the Royal Canin Kitten was pretty trash as far as the ingredients.
Since she was eating more dry than wet and was starting to gain too much weight, I switched her to their Core line of kitten food. It has better ingredients. It’s more expensive for the wet food, but I’m feeding one can a day instead of two, so the cost is roughly the same. For the last couple of months I quite free feeding and went based on their recommendation. They recommend for her age, that she gets one 3oz can of wet food and 1/2cup of dry food. I giver the wet and 1/4cup in the morning and 1/4cup in the evening.
I think that two issues contributing to her weight gain is that it’s Winter and activity levels are down. In the summer and fall, we sat out on the porch and she chased moths for a couple of hours every evening. She goes out some, but not much. Also, the Wellness Core Kitten Dry is 18% fat content. I don’t know how this compares to other brands, but this brand has an adult dry food fat content of 12% on the standard and 10% on the weight maintenance food. So she’s getting much more fat than she will on an adult food.
My question is, with her heading toward being over weight, do I let her keep turning into a chonker till 12months and then put her on a diet so she hits her max growth potential, or do I keep her on the kitten wet and switch her to an adult dry food with a lower fat content? I just don’t know if she’ll be missing out on key nutrients if I take her off kitten food now. Thanks. Sorry for all the back story. | 2020/01/28 | [

] | How much does your kitty weigh?
I’m not a vet, so I may not be 100% correct in my suggestions. (Of course if you have really pressing concerns about this, you should talk with a vet). With that being said, I think it is pretty typical for kittens to rapidly gain weight. I believe our kitten gained about 1 pound per month since we’ve had him. He is probably around a year old and now weighs 9 pounds.
I heard something online about dry food being for human convenience. You’ll hear all sorts of things about how many times a day you should feed your cat. I’m not sure what is right, but what we do is follow the recommended servings on the bag. For us, we give him his food at night (all the servings he would need) and not refill until the next night. If it runs out, it runs out. We don’t constantly refill it, which could lead to overeating. I know a lot of people do a serving in the morning and then at night. We switched to only nighttime feeding so the cat wouldn’t wake us up for more food.
There are also some “weight management” options some brands offer. I saw some at petsmart the other day. That could be a good option along with controlled amounts of food. Also, there are some cat BMI charts you can find online for a reference of what is a good weight/size for a cat.
But in the end I always recommend talking with a professional! | Kitten Foods is proven to have more nutrients than adult food and can contribute to fast weight gain. Once you run out of kitten food, I would switch to adult food. For now, however, it may be best to give your kitten plenty of exercise. It isn't a huge deal if your kitten is a few pounds (2-3 lbs.) overweight, but if you personally are concerned, lots of exercise and adult food.
However, reading your comment on depriving of nutrients in adultsfood, always remember, your kitten might thin out over time. Some kittens grow out and then up, and vice versa! |
649,218 | I am reading about centrifugation and I can't understand what forces are responsible for the sedimentation and how the motion of particle can be explained in an inertial frame. I can understand sedimentation in a stationary fluid. All the explanations I have found are the following:

But I would like an explanation based in an inertial frame. My current explanation is that the forces that a particle "feels" are not enough to keep it in circular motion. But then I can't understand why it must move vertically (sedimentation) and not horizontally. I have drawn also a free body diagram but still can't grasp why a particle settles down. I am not even sure if the direction of buoyant force is correct or it should be in the direction of drag.

] | An explanation in the inertial frame is annoying and unnecessarily complicated. This is exactly the sort of situation where non-inertial frames are best used: they simplify the calculation immensely. However, it is possible to do the unnecessarily complicated analysis in the inertial frame. To simplify the analysis a little we will put the centrifuge in space so that there is no gravity. Sedimentation will still occur.
First, consider a small parcel of the fluid. The fluid parcel moves in uniform circular motion so it is subject to a centripetal force. The only force acting on that parcel is the pressure. That means that the pressure cannot be uniform, but rather must be greater on the outside than on the inside. Specifically, the difference in pressure force is equal to the mass of the parcel times the centripetal acceleration. This keeps the fluid in uniform circular motion.
Now, consider a chunk of sediment the same volume as the parcel. The pressure gradient is the same for the chunk as it is for the fluid, and it’s volume is the same too. So the force acting on the sediment chunk is the same as the force acting on the fluid parcel. But since it’s mass is larger, this force is insufficient for uniform circular motion at the radius of the centrifuge. This means that it does not accelerate inwards sufficiently to stay at the same radius, and therefore it moves to a larger radius. This continues until the chunk reaches the wall of the tube which can exert a force sufficient to provide the centripetal acceleration necessary for uniform circular motion at the radius of the centrifuge.
Now that we have understood the pressure gradient, or buoyancy, in the inertial frame then the drag and other forces can be added unchanged from the standard non-inertial analysis. | There are many applications of centrifugation, they all have this in common: the device is pulling G's.
Here on Earth the Earth's gravity is pulling 1 G.
Let's say that you have boarded some carnival ride, and the angular velocity and diameter are such that the centrepetal acceleration is pulling 1 G too.
Inertial mass and gravitational mass are equivalent. Here the two directions of pulling G's are perpendicular so you can calculate the resultant amount of G's that is being pulled with Pythagoras' theorem.

We have placed our domain entitities into a domain layer and for each domain entity we have a MetadataType class which contains the applicable business rules in the form of annotations. The domain entity class also implements IValidatableObject for any validations that not implemented using DataAnnotations.
In the Web/presentation layer we are using view model objects. These could be data from multiple domain entities or a single domain entity, for now lets presume a single domain entity. This model view is decorated with [MetadataType(typeof(DomainEntityMetaData))]
This keeps our business logic in the domain and out of the view models. However, the view model does not implement IValidatableObject and as such this is never executed. I obviously do not want to repeat the validation in the view.
Any suggestions on how to approach this? | 2012/02/25 | [

] | Part of your problem here is that you're trying to carry through your domain validation into your view. While that can work in some situations, it's really a violation of the Seperation of Concerns principle. View and Domain are different concerns, and they each have their own validation concerns.
This is particularly a problem because your ViewModel objects are not identical to your domain model objects, yet you're trying to utilize domain metadata as the validator for your view model. That's always going to cause problems.
for instance, you might have a wizard that steps through the creation of a domain object across multiple pages. If you carry your domain validation through, you will have validation problems because you're not filling in required data in various steps.
Regardless of what domain validation you may have in place, you have to define your view validation. This may mean duplicating metadata.
Seperation of concerns is often at war with DRY (don't repeat yourself). If you want to prefer DRY over SOC then you will need to merge your domain models into your view models and use the same model for both.
It gets confusing when you use two different princples in your application. You're using SOC in your domain, and you want to use DRY in your view. That just doesn't work in many cases. I have no idea why you are trying to decorate your View models with domain metadata attributes. Obviously your view model is not the same as your domain model, so trying to use the domain metadata is going to result in an impedence mismatch.
That's not to say that you can't solve your problem. You probably could, but it would require hacking around the basic design of MVC, adding your own extension pieces, etc.. The question is, how much work do you want to do to save yourself some work? | May be following links have the answer you are looking for .(As question description is not very clear).

] | You still need a server, if you want to run any java code on your server. Such as code for talking to your database.
Gwt only does 2 things:
1: is is handling the client side, where it generate javascript from your java code.
2: It includes a .jar file, which can be used together with a java servlet server such as apache tomcat to serialize java objects which can then be send between the client and the server. And this .jar file will serialize all needed objects. And gwt will generate the needed javascript code.
Gwt does not itself include any http server. The address <http://localhost:9876> is only used to configure gwt. It is just a page with 2 buttons to turn dev mode on/off.
The eclipse plugin does include a embeded webserver which can be used for gwt development. I have newer done this and I think that installing an independent java tomcat server is the best solution.
But if you want to use the eclipse embeded webserver you need the "Run in development mode with Jetty." - Jetty is the name of the embeded java servlet server. | Are you using the plugin from Google ?
If so, this is outdated. I advice you to use the plugin from branflake. You can find this plugin on GitHub : <https://github.com/gwt-plugins/gwt-eclipse-plugin>

My advice is to watch these YouTube videos to get you started. If you follow them all should be working without a problem.

54,472 | I have a training workflow requirement where the administrator uploads a document to a document library, which will initiate a training workflow. The workflow will consist of specifying which documents the users have to read, the due date , select affected users from AD, choose whether to send the users an email or not to say that training is available. Also choose when a user finishes this training (through another workflow discussed below) , send an email to Admin saying the user has completed the training.
The admin should have a "View" where he/she can see which users have completed the training and which haven't.
The users need to have a webpage on Sharepoint where they can see the training assigned to them. They click on say "Begin training", it will point to the document that admin uploaded, they will read it and the next step would be to acknowledge that they have read the document and mark training as finished. Depending on whether the admin had set up the notification, an email will be sent to the admin that the user has finished the training. Most likely admin won't need this feature but just in case.

] | You actually setup the alias's on the SharePoint servers, not the SQL servers. Run
c:\Windows\System32\cliconfg.exe
on each of your SharePoint servers and then create a new alias with the "Server alias" being the same sql name and instance of sql 2005 and the servername being the name and instance of your sql 2008.
After doing that, make sure all of the DBs are on the SQL 2008 instance and restart all of your SharePoint servers. Assuming everything is setup correctly, SharePoint will now be going to your SQL 2008 box for DBs instead of the SQL 2005 one. All of the DBs on SQL 2005 are unaffected by this change and any other applications still using the SQL 2005 DBs (as long as those apps don't live on the SharePoint boxes) should connect just fine to the SQL 2005 DBs.
The best practice I follow is when installing SharePoint, I got ahead and create sql aliases for my SQL instances I plan on using. The alias names I usually use are SPSQL01, SPSQL02, etc. This way if my sql names change or I need to upgrade SQL, all I need to do is change my aliases on the SharePoint servers to point to the new server.
I hope this makes sense. | What Steve said is correct. I used this method to move from a 32 bit instance of SQL 2005 to a 64 bit edition of 2008 R2 in preperation for the upgrade from MOSS 2007 to Sharepoint 2010. You set up the alias on the Sharepoint server, not the SQL server. It works great. Just keep in mind that it any request made to the old database server will be routed through the alias so make sure you move all of your databases to the new database server. |

When integrating studio strobes with speedlights, there are two things to consider. Whether you want more control than manual-only triggers give you for either the strobes and/or the speedlights, and how robust you want the triggers to be.
Are there OEM/3rd party triggers to command the studio strobe?
--------------------------------------------------------------
Some studio strobes are manufactured by companies that also make triggers specifically for that family of strobes. And in some cases (Profoto, Paul Buff, etc.) these triggers can offer you remote control over the studio strobe power levels, and the ability to sync at shutter speeds above x-sync. Because the integrated power control of the studio strobe has to be built into the strobe, it's unlikely that any 3rd-part triggers can offer this function. However. That same power control may not be available with any speedlights, just as TTL triggers for speedlights probably can't control power for the studio strobes. It may come down to a one-or-the-other side trigger. Say, Paul Buff Cybersyncs with a Cyber Commander or Profotos with Air Remote TTL, but manual-only control of a 580EXII. Or you could sandwich a TTL trigger into the OEM triggering scheme and use two systems simultaneously. Or you could control both your strobes and your TTL OEM speedlights using systems like RadioPopper's Jr2 triggers, or PocketWizard's TTL triggers with an AC-3 zone controller and appropriate strobe adapters. Or maybe you *really* want TTL/HSS and integrated speedlights and studio strobes, so you're picking up a Phottix Indra and some Odin triggers; or going with [the Godox X system](http://flashhavoc.com/godox-flash-system-overview/) of speedlights, bare bulb flashes, and studio strobes.
Also consider that many triggers for HSS/TTL only work for Canon and Nikon, and don't come in the mirrorless flavors. Some do. Think of future expansion not just of your lights, but also of your cameras. Are you going to shoot multiple systems or share with another photographer who shoots a different system?
3rd party manual trigger considerations
---------------------------------------
If you decide that you're happy walking up to any and all of your lights to make power adjustments, and manual triggers are OK for you, then any and all 3rd party triggers are liable to work equally as well as OEM triggers--and they may be easier to use to integrate the studio strobes with your speedlights, and it just comes down to reliability and cost. If you're doing pro work and need rock-solid reliability, then PocketWizard Plus units are liable to be worth looking at. Triggers, obviously, are many and varied which is why you came looking for an answer to this question, but this is also one area where the technology and feature sets move swiftly and models are always on the churn.
Keeping Up-to-Date

Looking at the original 2010-2011 answers here, nearly every one of the trigger models mentioned has been "refreshed" (PocketWizard came out with the PlusX, RadioPopper now has the Jr2, and the Cactus V5 and Yongnuo RF-603IIs are the latest cheapie manual triggers), and the cheap 3rd party TTL triggers (Phottix Odin, Pixel King, Yongnuo YN-622) have hit the scene. Over the next year or so, manual triggers with remote power control appear to be the coming thing. The recent release of the Cactus V6 triggers and RF60 speedlight, and announcement of the Yongnuo YN-560-TX transmitter for remote power control of a YN-560iii to be released this summer are probably just the beginning of this wave. In the few days since initially writing this answer, I've already had to update it for the RP Jr2; if you're reading this post-2014, possibly every model in this paragraph will have been refreshed.

The Cactus V4 are reported to be better, but I do not own these, so I cant tell from personal experience. |

] | **Easy Solution**
Ironically, it is probably Firebug which is slowing down Google Maps for you so much. To increase performance, the easiest thing would be to disable Firebug when you're not doing development.
**Better Solution**
Unfortunately, often times disabling such a useful tool is not an acceptable solution. Thankfully it's only a few components of Firebug that play the biggest role in slowing things down. The biggest performance gains come from disabling the "console" and/or "net" tabs, either by clicking them and deselecting enabled, or going through the options tab. Firebug's performance hit is most noticeable on Google Maps because of the large amount of requests it makes and the complex DOM structure.
**Backup Plan**
If that doesn't help, you can try updating Firefox and Firebug and hope that they've improved performance in recent versions. The most recent version as of when I am writing this is Firebug 1.10.0a7 for Firefox 12, and on my machine it seems to perform reasonably well even with net and console enabled. | Consider using [maps.bing.com](http://maps.bing.com): I'm not sure what it is about google maps that makes firefox slow, but it's not just a browser issue; bing maps doesn't have the issue. (indeed, chrome seems to exhibit oddly unsharp tiles when scrolling on bing maps, in a fashion reminiscent of firefox's [quirks](https://support.mozilla.org/en-US/questions/928702) on google maps).
I hope firefox finds a solution, because I'm not holding my breath for google to. |

On one hand I want to provide avenues for them to be successful by ensuring they know the systems they are working in, proper workflows, and helping them along with problems when they request support.
However I've noticed the more I provide assistance, the more they request help and furthermore in the case of the intern it seems the things I teach them go in one ear and out the other.

] | **Short answer:** Teach your people how to solve problems, not tell them the answer.
I have been in this exact situation a number of times over the years. If I allowed them to, the junior staff would have consumed all my time helping them solve their problems. What I did was to show them the steps I went through to find the solution, rather than just tell them the answer. Of course they will keep coming back to you as they do this the first few times, but this should lessen as they gain experience.
You can then slowly wean them off asking *you* for help because instead, you can direct them to say, "How have you tried to resolve this? Is this a similar problem to what you have tried to solve before? How did you solve that problem?" They can then go off and try to work their way further through the problem, and hopefully start to understand *how* they are working through it.
It's very much like teaching a person to fish. You will find you can slowly wean them off being dependent on you and learn to be self reliant by understanding the problem solving process. And that will give you some very valuable resources in future! :) | If someone comes to me and asks for help over an issue they have seen before, then I tell them to sit back, relax and I ask them how did we handle that issue the last time. I expect the intern to remember the key details and go over with me about how they handled it. I fill in whatever blanks are needed and once I am confident that they know what they have to do, I tell them to get out of my office :)
The first time, I may or may not hand in an answer, all tied up and gift-wrapped. The second time we run into the same issue, I make them work at getting the answer. |

And that will give you some very valuable resources in future! :) | You are in a mentoring/training relationship. There is no one right way to handle this situation, and there are no simple answers for HOW to do it effectively.
You might be successful with the advice given here, or you might find some other way to do it. Whatever the case, this is NOT an easy endeavor. It should be taken as a serious part of your daily work, not as some side-task where you can simply apply a few tips and tricks. In other words, it WILL take time out of your day and you must factor this into your other responsibilities. You basically have to carve out significant chunks of time and effort to do this right.
The good news is that training people can be highly rewarding to you personally, to the organization and to the students.
Pedagogy (teaching) requires the teacher (you) to evaluate the students and to take different actions depending on this evaluation. If you haven't taught before now would be a good time to research into it and start practicing this stuff.
There's no magic ratio of "spoon-feeding" to "self-reliance". If you think that your students aren't absorbing the information you're giving them, there could be any number of reasons for that: perhaps they need more practice? perhaps the information was not presented correctly? perhaps they don't have enough context? Whatever the case, you have to find out what the real problem is and address it (and no, the problem is NOT usually that the students are dumb or lazy). |

One of the main goals of Stack Exchange, as I understand it, is to improve the internet by providing better or more relevant answers to Google search queries than other internet sites. I don't think this question does this.
I would be against deleting questions like the following
* [Is there a phrase that means sleeping with someone without sex?](https://english.stackexchange.com/questions/148323/is-there-a-non-sexual-phrase-for-sleeping-with-someone)

* [How do you quote a passage that has used '[sic]' mistakenly?](https://english.stackexchange.com/questions/24750/how-do-you-quote-a-passage-that-has-used-sic-mistakenly)
* [What gender is generally associated with "toad" characters in English fiction and folklore?](https://english.stackexchange.com/questions/12634/gender-generally-associated-with-toad-characters-in-english-fiction-and-folkl)
because these questions have more answers, and each answer seems to be more valuable. What I mean by this: the answers are mostly original content rather than quotations, they are longer rather than shorter, and they seem to have more effort put into them (which makes it harder to reproduce them if the question is deleted). While the questions themselves may be off-topic, I don't want to delete bad or off-topic questions that have accumulated good answers.
**Reopen**: I don't think it should be reopened, because I don't think there's anything significant that a new answer could added. It's a straightforward question with a straightforward answer. In addition, reopening it, combined with its high vote count, might send the message that we welcome this kind of question, which is bad because it is clearly off-topic by today's standards. That said, I don't think it would actually change much if we reopened it, but I don't understand why some people think it would be a good idea to do this.
**Historical locking** seems OK. To me, the biggest plus to this is that it gets taken off the list of top-voted questions (historical locked questions only show up in search results, not in lists). The downside is that we're stuck with it forever. | We should just leave it closed. The advantage over deleting it is that it can be a duplicate target. |

There's been a lot of discussion on Meta in the comments about this question recently, but it's actually not the main topic of any of the recent questions. I thought I'd post a new question dedicated to this topic, so that people can keep all their discussion about it in one place.
I see several options:
* we can leave it as closed
* we can give it a [historical lock](https://meta.stackexchange.com/questions/126587/what-is-a-historical-lock-and-what-is-it-used-for)
* we can reopen it (there was one vote for this last time I checked)
* we can delete it (there was also one vote for this)
Which of these do you think is best, and why?
**Update:** As of March 18, 2016, the question has a historical lock. | 2016/03/16 | [
"https://english.meta.stackexchange.com/questions/7829",
"https://english.meta.stackexchange.com",
"https://english.meta.stackexchange.com/users/77227/"
] | I asked a question about how to request a historical lock for old but seemingly popular questions that don't meet current site standards for preliminary research (or some other criterion) here: [How can users nominate old, popular questions for exemption from closure as being of 'historical value'?](https://english.meta.stackexchange.com/questions/7823/how-can-users-nominate-old-popular-questions-for-exemption-from-closure-as-bein)
Since I stated explicitly there that my preference would be to preserve the "bare/bear with me" question in a locked state, it's only fair that I expose myself to the wrath of close/delete proponents by reiterating that preference here. Neither the "bare/bear with me" question nor the two answers it drew are especially substantial, but more than a million people have viewed the page since it was posted in August 2010. And though the coverage isn't deep, it is clear and accurate.
I suspect that much of the debate over this question comes down to whether (on the one hand) you think that the "bare/bear with me" question lowers the prestige of English Language & Usage and encourages similar low-brow questions from people who see it, or whether (on the other hand) you think that the primary goal of EL&U is to provide useful answers to questions of English language and usage that people are interested in, regardless of their level of sophistication. As this description of the two viewpoints indicates, it is easy for proponents of either view to talk past the other because one view does not obviously and directly entail the negation of the other.
I'm not embarrassed by the existence of the "bare/bear with me" Q&A on our site, and I think that its presence is unrelated to the flood of low-end questions that arrive here day after day. Those things happen, I believe, because the vast majority of visitors to this site are neither experts nor advanced enthusiasts when it comes to the English language. They are people who want their English-related question answered, and who either ask it here or search Google and find a related answer posted here. This is the central fact that phenry in his famous Meta post [This is not a site for "serious English language enthusiasts," and it never will be](https://english.meta.stackexchange.com/questions/4491/this-is-not-a-site-for-serious-english-language-enthusiasts-and-it-never-will) insists upon: most people who use EL&U are not looking for complicated, recondite explanations of advanced linguistic phenomena; rather, they want to know the name of a color that is somewhere between crimson and scarlet, or a word that means you kind of think someone's a jerk but your mind isn't entirely made up, or the difference between *start* and *begin*, or whether you should use "bare with me" or "bear with me."
Five and a half years after the "bare/bear with me" question was posted, no one has attempted to provide a deep answer to it, which suggests to me that no one here who is capable of such an answer is inclined to provide it. That may be because knowledgeable people consider it a fundamentally uninteresting question—but their lack of interest in the question obviously doesn't extend to the Internet community at large. In any case, the 125 people who have upvoted the "bare/bear with me" question and the 224 people who have upvoted the accepted answer to it aren't zero-rep fly-by users: they are Stack Exchange participants who, one way or another, accumulated enough reputation points to cast upvotes on EL&U posts. (I am not among them, by the way.)
Still, if no one has cared to improve on the concise answers posted five years ago, I see little reason to reopen the question (which was closed earlier this month) just to make additional answers theoretically possible. That's why I would prefer to see the page given locked status. That way, it can continue to provide quick practical advice to the many people who continue to find it in Google Searches, without having the cloud of "CLOSED [for lack of adequate research]" hanging over it, and without the threat of its being deleted outright and inviting new rounds of questions about the difference between *bare* and *bear* from inquisitive visitors who find their way to EL&U.
So, to summarize, I favor the locked preservation option for the "bare/bear with me" question because (1) I think the page is useful to people who seek it here or on Google; (2) I think the locked status draws a useful line between questions that satisfied older EL&U standards but don't satisfy current standards, and questions that do meet current standards; (3) I don't think the existence of historically locked questions harms the site; and (4) I think older questions that have earned many upvotes over the years deserve a degree of respect and tolerance for having done so.
By the way, no one as yet has detailed the steps involved in giving a question a historical lock. I continue to hope that someone will provide such an answer. [[**UPDATE, 3/18/16:** Sumelic's answer to my "How can users nominate..." question appears to be a definitive response; I followed the method it described (namely, flagging the moderators with a request for a lock) in seeking a lock for the bare/bear question (as others may have done, too), and a moderator responded to the request(s) by locking the question—without reopening it, I might add. The result is that the question remains closed but is no longer in danger of being deleted. Thanks, mods!]] | For what it's worth, here's my opinion, partially copied from some comments I left earlier.

A user said the question has a historical value, but I beg to differ. The question is just a general reference question without any research effort. There is nothing common between the two words etymologically or meaning-wise. The question is no better than "what is the difference between hair and hare?"
English Language and Usage (ELU) wants to differentiate its name from Yahoo Answer type of communities where you can ask whatever you want in any format. If we allow the question to remain undeleted, it will mislead users into believing that such a question had been accepted and welcomed for more than five years and it was belatedly found out by the community. What message does it give to new and future users?
I remember one new user quoted an old question which is asking for a list of words with a "historical lock" and asked. "Why can't I ask this question while you allowed this question in the past?" even though there was a clear comment by Andrew Leach stating "this question should not be used as an example for a future general reference question" (I don't remember it word for word). What if another user uses the question as an excuse or to insult or mock the integrity of this community?
The number of questions on ELU is reaching 70,000 soon and it will be more than 100,000 next year. We have to think about this. What benefit does it give to this community to let it remain on this site? What is the cost against the apparent benefit coming from removing the question from ELU?
Please read the [Yahoo Answers link](https://answers.yahoo.com/search/search_result?fr=uh3_answers_vert_gs&type=2button&p=difference%20between%20bear%20and%20bare) and see how exactly the question looks like those on Yahoo Answers.

The post date was Jan. 30, 2011 and the deletion date was Sep. 19, 2012. If the question had not been deleted, it could have generated far more views and upvotes. Who knows? What justifies deleting this question and what justifies leaving the "bear/bare" question closed? We deleted a very popular question with a lot of upvotes. Why can't we delete the "bear/bare" question? I don't see any difference between the two questions, but if someone asks me to choose only one between the two to delete, I will choose the "bear/bare" question.
Are we aiming for double standards? The Original Poster of the "TL;DR" question and answers were just unlucky while the "bear/bare" posters are very lucky to have your sympathy? Where is fairness? |

We deleted one-and-a-half-year old question for the same reason, [What does “TL;DR:” mean?](https://english.stackexchange.com/questions/10659/what-does-tldr-mean#comment111627_10659) (sorry for users with less than 10,000 reputation points that you can't read it) with 2,755 views, 30 upvotes for the question, and 59 upvotes for the top ansewer, 9 upvotes for the second answer. The post date was Jan. 30, 2011 and the deletion date was Sep. 19, 2012. If the question had not been deleted, it could have generated far more views and upvotes. Who knows? What justifies deleting this question and what justifies leaving the "bear/bare" question closed? We deleted a very popular question with a lot of upvotes. Why can't we delete the "bear/bare" question? I don't see any difference between the two questions, but if someone asks me to choose only one between the two to delete, I will choose the "bear/bare" question.
Are we aiming for double standards? The Original Poster of the "TL;DR" question and answers were just unlucky while the "bear/bare" posters are very lucky to have your sympathy? Where is fairness? |
7,829 | [Is it "bear" or "bare" with me?](https://english.stackexchange.com/questions/1269/is-it-bear-or-bare-with-me)
There's been a lot of discussion on Meta in the comments about this question recently, but it's actually not the main topic of any of the recent questions. I thought I'd post a new question dedicated to this topic, so that people can keep all their discussion about it in one place.
I see several options:
* we can leave it as closed
* we can give it a [historical lock](https://meta.stackexchange.com/questions/126587/what-is-a-historical-lock-and-what-is-it-used-for)
* we can reopen it (there was one vote for this last time I checked)
* we can delete it (there was also one vote for this)
Which of these do you think is best, and why?
**Update:** As of March 18, 2016, the question has a historical lock. | 2016/03/16 | [
"https://english.meta.stackexchange.com/questions/7829",
"https://english.meta.stackexchange.com",
"https://english.meta.stackexchange.com/users/77227/"
] | I asked a question about how to request a historical lock for old but seemingly popular questions that don't meet current site standards for preliminary research (or some other criterion) here: [How can users nominate old, popular questions for exemption from closure as being of 'historical value'?](https://english.meta.stackexchange.com/questions/7823/how-can-users-nominate-old-popular-questions-for-exemption-from-closure-as-bein)
Since I stated explicitly there that my preference would be to preserve the "bare/bear with me" question in a locked state, it's only fair that I expose myself to the wrath of close/delete proponents by reiterating that preference here. Neither the "bare/bear with me" question nor the two answers it drew are especially substantial, but more than a million people have viewed the page since it was posted in August 2010. And though the coverage isn't deep, it is clear and accurate.
I suspect that much of the debate over this question comes down to whether (on the one hand) you think that the "bare/bear with me" question lowers the prestige of English Language & Usage and encourages similar low-brow questions from people who see it, or whether (on the other hand) you think that the primary goal of EL&U is to provide useful answers to questions of English language and usage that people are interested in, regardless of their level of sophistication. As this description of the two viewpoints indicates, it is easy for proponents of either view to talk past the other because one view does not obviously and directly entail the negation of the other.
I'm not embarrassed by the existence of the "bare/bear with me" Q&A on our site, and I think that its presence is unrelated to the flood of low-end questions that arrive here day after day. Those things happen, I believe, because the vast majority of visitors to this site are neither experts nor advanced enthusiasts when it comes to the English language. They are people who want their English-related question answered, and who either ask it here or search Google and find a related answer posted here. This is the central fact that phenry in his famous Meta post [This is not a site for "serious English language enthusiasts," and it never will be](https://english.meta.stackexchange.com/questions/4491/this-is-not-a-site-for-serious-english-language-enthusiasts-and-it-never-will) insists upon: most people who use EL&U are not looking for complicated, recondite explanations of advanced linguistic phenomena; rather, they want to know the name of a color that is somewhere between crimson and scarlet, or a word that means you kind of think someone's a jerk but your mind isn't entirely made up, or the difference between *start* and *begin*, or whether you should use "bare with me" or "bear with me."
Five and a half years after the "bare/bear with me" question was posted, no one has attempted to provide a deep answer to it, which suggests to me that no one here who is capable of such an answer is inclined to provide it. That may be because knowledgeable people consider it a fundamentally uninteresting question—but their lack of interest in the question obviously doesn't extend to the Internet community at large. In any case, the 125 people who have upvoted the "bare/bear with me" question and the 224 people who have upvoted the accepted answer to it aren't zero-rep fly-by users: they are Stack Exchange participants who, one way or another, accumulated enough reputation points to cast upvotes on EL&U posts. (I am not among them, by the way.)
Still, if no one has cared to improve on the concise answers posted five years ago, I see little reason to reopen the question (which was closed earlier this month) just to make additional answers theoretically possible. That's why I would prefer to see the page given locked status. That way, it can continue to provide quick practical advice to the many people who continue to find it in Google Searches, without having the cloud of "CLOSED [for lack of adequate research]" hanging over it, and without the threat of its being deleted outright and inviting new rounds of questions about the difference between *bare* and *bear* from inquisitive visitors who find their way to EL&U.
So, to summarize, I favor the locked preservation option for the "bare/bear with me" question because (1) I think the page is useful to people who seek it here or on Google; (2) I think the locked status draws a useful line between questions that satisfied older EL&U standards but don't satisfy current standards, and questions that do meet current standards; (3) I don't think the existence of historically locked questions harms the site; and (4) I think older questions that have earned many upvotes over the years deserve a degree of respect and tolerance for having done so.
By the way, no one as yet has detailed the steps involved in giving a question a historical lock. I continue to hope that someone will provide such an answer. [[**UPDATE, 3/18/16:** Sumelic's answer to my "How can users nominate..." question appears to be a definitive response; I followed the method it described (namely, flagging the moderators with a request for a lock) in seeking a lock for the bare/bear question (as others may have done, too), and a moderator responded to the request(s) by locking the question—without reopening it, I might add. The result is that the question remains closed but is no longer in danger of being deleted. Thanks, mods!]] | We need to have one standard that is applicable to all the questions regardless of when it was asked, how many views it generated, how many upvotes it has. They are all irrelevant when we decide to close it or even delete it.
A user said the question has a historical value, but I beg to differ. The question is just a general reference question without any research effort. There is nothing common between the two words etymologically or meaning-wise. The question is no better than "what is the difference between hair and hare?"
English Language and Usage (ELU) wants to differentiate its name from Yahoo Answer type of communities where you can ask whatever you want in any format. If we allow the question to remain undeleted, it will mislead users into believing that such a question had been accepted and welcomed for more than five years and it was belatedly found out by the community. What message does it give to new and future users?
I remember one new user quoted an old question which is asking for a list of words with a "historical lock" and asked. "Why can't I ask this question while you allowed this question in the past?" even though there was a clear comment by Andrew Leach stating "this question should not be used as an example for a future general reference question" (I don't remember it word for word). What if another user uses the question as an excuse or to insult or mock the integrity of this community?
The number of questions on ELU is reaching 70,000 soon and it will be more than 100,000 next year. We have to think about this. What benefit does it give to this community to let it remain on this site? What is the cost against the apparent benefit coming from removing the question from ELU?
Please read the [Yahoo Answers link](https://answers.yahoo.com/search/search_result?fr=uh3_answers_vert_gs&type=2button&p=difference%20between%20bear%20and%20bare) and see how exactly the question looks like those on Yahoo Answers.

] | A hardware thread (logical core) that's stalled on a cache miss can't be doing anything else, so it still counts as busy for the purposes of task-managers / CPU time accounting / OS process scheduler time-slices / stuff like that.
This is true across all architectures.
Without hyperthreading, "hardware thread" / "logical core" are the same as a "physical core".
Morphcore / other on-the-fly changing between hyperthreading and a more powerful single core could make there be a difference between a thread that keeps many execution units busy, vs. a thread that is blocked on cache misses a lot of the time. | I don't get the link between the OS CPU usage statistics and the optimal use of the pipeline. I think they are uncorrelated as the OS doesn't measure the pipeline load.
I'm writing this in the hope that Peter Cordes can help me understand it better and as a continuation of the comments.
---
User programs relinquish control to OS very often: when they need input from user or when
they are done with the signal/message. GUI program are basically just big loops and at
each iteration control is given to the OS until the next message.
When the OS has the control it schedules others threads/tasks and if not other actions
are needed just enter the idle process (long time ago a tight loop, now a sleep state)
until the next interrupt. This is the Idle Time.
Time spent on an ISR processing user input is considered idle time by any OS.
An a cache miss there would be still considered idle time.
A heavy program takes more time to complete the work for a given message thereby returning
control to OS say 2 times in a second instead of
20.
If the OS measures that in the last second, it got control for 20ms only then the
CPU usage is (1000-20)/1000 = 98%.
This has nothing to do with the optimal use of the CPU architecture, as said stalls can
occur in the OS code and still be part of the Idle time statistic.
The CPU utilization at pipeline level is not what is measured and it is orthogonal to the
OS statistics.
CPU usage is meant to be used by sysadmin, it is a measure of the load you put on a system,
it is not the measure of how efficiently the assembly of a program was generated.
Sysadmins can't help with that, but measuring how often the OS got the control back (without
preempting) is a measure of how much load a program is putting on the system.
And sysadmins can definitively do terminate heavy programs. |

220,928 | Can a wizard or witch recognize a Maledictus? What about a Parselmouth?
Can they, without asking the serpent, recognize if it once had human form? | 2019/10/02 | [
"https://scifi.stackexchange.com/questions/220928",
"https://scifi.stackexchange.com",
"https://scifi.stackexchange.com/users/122007/"
] | **No, they can't, or at least not just by looking.**
In *Crimes of Grindlewald* it is revealed that Nagini was a Maledictus, and in the original movie series several wizards - including Harry, who was a Parselmouth - encountered Nagini without ever realizing she was anything other than a snake.
There are probably spells that could reveal the truth, if the wizard became suspicious. But it isn't something a wizard can *just sense,* in the way a powerful wizard like Dumbledore can *just sense* the presence of magic in an apparently natural setting.
... that does still leave the possibility that an *experienced* Parselmouth, one who knows about and has encountered several snake Maledictuses previously, might be able to spot some tell-tale signs. But as Maledictuses are very rare, and they don't all take the same form anyway, this seems unlikely to happen. | Probably not - they can’t with Animagi.
=======================================
There isn’t enough information on Maledictuses to state conclusively whether wizards could tell one from a regular animal on sight. No one in the original Harry Potter books seemed to ever suspect Nagini was anything but a snake, but her case may not be a typical example of a Maledictus, as she was also owned by the Dark Lord and turned into one of his Horcruxes, so he would have magically altered her by then. It isn’t shown yet whether wizards recognize her as a Maledictus before she came into the Dark Lord’s possession. However, what *is* known is that wizards don’t recognize Animagi (who, though different from Maledictuses, are also humans transformed into animals) on sight. Because it can easily be used as a disguise, Animagi must register their animal form with the Improper Use of Magic Office.
>
> “It takes years to become an Animagus, and then you have to register yourself and everything,’ said Hermione vaguely, now squinting down the index of Weird Wizarding Dilemmas and Their Solutions. ‘Professor McGonagall told us, remember … you’ve got to register yourself with the Improper Use of Magic Office … what animal you become, and your markings, so you can’t abuse it …”
> *- Harry Potter and the Goblet of Fire, Chapter 26 (The Second Task)*
>
>
>
Wizards can recognize Animagi if they know their animal form, but if they don’t, it’s very unlikely they’ll recognize them on sight as Animagi rather than ‘real’ animals.

Therefore, without any specific information on whether wizards can recognize Maledictuses on sight, for now the most logical speculation would be that they cannot, similarly to how they’re unable to tell Animagi from regular animals just by looking at them. |

Installation is the reverse of removal. :) It should just snap in after the pins of the bulb are seated. | Assuming these are push-in, two pin bulbs, you don't need to take it apart.
Use a small suction cup to pull the lamp out from its face.
Use a small wooden stick stuck between the louvers to push the bulb out from behind.
Use a plastic (non conductive) screwdriver stuck under the base of the lamp, through the louvers, to pry it away from the fixture.
Maybe the louvered part of the fixture unscrews from the domed part of each bulb holder. That would make it easier. |

The tip connects to a Maxim One-Wire memory in the power supply that is read by the computer to obtain information such as power supply capability, serial number etc.
Be VERY careful if you probe the cable, if you accidentally short the centre pin to the inner cylinder it may destroy the One-Wire memory (on the one I investigated there was NO protection against this!).
If the memory is non-functional the computer will still be powered but it will assume it is a non-Dell low-power supply, it may reduce the speed of the computer to minimize power consumption and may refuse to charge the battery.

That's correct. The tip is a 3rd conductor carrying some sort of signalling between the adapter and the computer. |

* This isn't straightforward electronics. So it excludes a lot of people (like me) who aren't comfortable with relatively high-frequency black magic analog electronics.
* Answering your question requires to 100% understand your design, your constraints, and the choices you made, which likely implies spending a significant proportion of the time you spent on it yourself (and it probably took much more time than the 15 minutes people generally take to answer a question). This is also probably the reason of the downvote.
* You seem to have made a good job already so maybe there isn't much to add, even for an expert. I would be tempted to think the realtively high number of upvotes confirms this. People usually don't upvote things they don't understand (and I didn't upvote your post - sorry - for this very reason: I'm actually unable to tell if it makes sense).

After a quick glance, this isn't the kind of question where I can get away with reading a headline, scanning for a obvious stupidity, then writing a simple answer. It looks like I'd have to read every word, and probably refer back and forth a few times. I notice there are 4 separate questions in there.
The schematics are well presented, but would require a few minutes to really understand what you are trying to do, how you went about it, and what problems there might be with that approach. That by itself might be OK, but not with all the other stuff around it. Then you're showing a layout, so at least part of this question is about layout too.
It's just too overwhelming to dig into. It crosses the line from casual free help to essentially a design review that would take some time. I charge for those.
This question should be broken into multiple individual questions. I just tried to close the whole thing as *too broad*, but the system didn't let me due to the open bounty.

] | You seem to have done a decent job writing the question, so I just went and upvoted it. However, I'm not going to answer it because, basically, it would be too much work.
After a quick glance, this isn't the kind of question where I can get away with reading a headline, scanning for a obvious stupidity, then writing a simple answer. It looks like I'd have to read every word, and probably refer back and forth a few times. I notice there are 4 separate questions in there.
The schematics are well presented, but would require a few minutes to really understand what you are trying to do, how you went about it, and what problems there might be with that approach. That by itself might be OK, but not with all the other stuff around it. Then you're showing a layout, so at least part of this question is about layout too.
It's just too overwhelming to dig into. It crosses the line from casual free help to essentially a design review that would take some time. I charge for those.
This question should be broken into multiple individual questions. I just tried to close the whole thing as *too broad*, but the system didn't let me due to the open bounty.
Remember that people here are volunteers you are asking for a favor. Keep it simple. Make people feel they can accomplish something with the limited free time they have to spend here. | I'm far from an expert in this specific field of electronics, but I may have a few clues on why it hasn't been answered:
* This isn't straightforward electronics. So it excludes a lot of people (like me) who aren't comfortable with relatively high-frequency black magic analog electronics.
* Answering your question requires to 100% understand your design, your constraints, and the choices you made, which likely implies spending a significant proportion of the time you spent on it yourself (and it probably took much more time than the 15 minutes people generally take to answer a question). This is also probably the reason of the downvote.
* You seem to have made a good job already so maybe there isn't much to add, even for an expert. I would be tempted to think the realtively high number of upvotes confirms this. People usually don't upvote things they don't understand (and I didn't upvote your post - sorry - for this very reason: I'm actually unable to tell if it makes sense). So, to some extent, this is a hint that some people may have understood your design, but couldn't think of anything more to improve it.
* At some point, the only thing that will tell if the design works is to test it. Maybe you've reached that point. |
6,483 | Original question: [Review request: DIY DC to 50MHz differential oscilloscope probe](https://electronics.stackexchange.com/questions/352304/review-request-diy-dc-to-50mhz-differential-oscilloscope-probe)
It is getting completely ignored (save for two comments), despite an outstanding bounty and several edits no narrow down the scope. I don't think that my question is too broad, too low effort or too niche for the knowledge of other users. At the time I'm writing this, it has four upvotes, one downvote and no close votes that I am aware of. What is wrong with my question, and how could I improve it? Is it just too boring to answer? Is this kind of question acceptance on this site? This led me to believe that it is: [Circuit review acceptable?](https://electronics.meta.stackexchange.com/questions/399/circuit-review-acceptable)

] | As others have stated, your question is simply too complex.
As a volunteer, seeing something as complete as that it tends to put me off. I could spend all day analysing and simulating parts of it but that really is way too much time for this hobby pastime. Moreover, without being able to sit down with it hooked up to a scope on the bench, a lot of anything I could say would be just hand-wavy generalizations.
In truth, if you need a proper review, you need someone local to help with hands on experience to really do it justice.
Further, that is also a pretty niche development area that many folks really do not have much experience with.
Me, and I am sure many others, just move on to the next question without giving it an up or down vote. | I'm far from an expert in this specific field of electronics, but I may have a few clues on why it hasn't been answered:

54,378 | I can't but think like a programmer here, although I'm aware that this can turn out as a silly question.
Would a user prefer a slider or buttons for zooming in/out?
- No default zooming factor
- There is a min and a max zooming factor
- Zoom steps are block-incremeneted; slider's moving piece would snap to zoom values | 2014/03/20 | [

] | The slider has many advantages over two buttons:
* single widget for single purpose (zooming)
* graphically shows the relative zoom factor
* indicates how much more zooming in/out is possible (the buttons' enabled state would only indicate when the min/max zoom level is reached)
* selection of the preferred zoom level by dragging (compared to clicking multiple times on the buttons, which gets even worse the more intermediate zoom values are introduced) | I know this may be a big ask, but pretty much every user has become so familiar with the functionalities available on Google Maps that they expect most zooming interfaces, especially maps, should behave in the following ways.
* Double Click to zoom in
* Use mouse wheel to zoom in or out
* Additional zoom slider control
* On a touch screen, two fingers pinch and expand control |
