1. Cultivate a philosophy of appreciation
When was the last time you were thrilled over something as simple as blowing bubbles? Cultivating a philosophy of appreciation is about seeing opportunities in the seemingly insignificant, and reframing them as important to your wellbeing.
2. Understand that life is made up of 'moments'
These are just as vital as conventional units of time. When you review your day ahead and think, 'Meeting at 1pm', also say, 'Moments matter', then make a pact with yourself to notice the sun break through the clouds, or the wind move through the trees.
3. Write a list of daily 'joys'
At the end of the day, create a list of things that stood out for you in a 'small pleasures' book. If you've had a tough day, you may have to work hard to find a positive moment. Even if it's, 'Drank the perfect coffee', that's something to find joy in.

On World Sparrow Day, move to monitor common birdsMarch 19th, 2012 - 10:32 pm ICT by IANS
Mumbai, March 19 (IANS) A unique public participation initiative to monitor common birds in the country will be launched Tuesday, to coincide with "World Sparrow Day", an official said here Monday.
The "Common Bird Monitoring Program", a pioneer project and first of its kind in India, will monitor and carry out detailed mapping of 18 common bird species found across the country with direct public participation, said Nature Forever Society chief Mohammed Dilawar.
The birds like house sparrows, house crow, rock pigeon, rose-ringed parakeets, Ashy Prinia and Hoopoes shall be monitored, mapped and counted around the country as well the entire Indian Subcontinent, including Pakistan, Bangladesh and Sri Lanka, Dilawar told media persons.
"The data collected will help map the presence/absence, population/distribution of these common birds since there is currently no scientific data available on these common species in India," Dilawar explained.
The initiative is supported by a corporate house, the Jaypee Group Executive Chairman Manoj Gaur and Jaypee Group's IT arm, JILIT's Director Sunita Joshi - the latter has taken care of the technology to design the program.
This data, over a period of time would be statistically analysed for launching conservation efforts, he said.
"The knowledge about the status, population and distribution of common birds will help in timely conservation measures that can save these birds from extinction, and help create conservation interest among the masses," said Dilawar.
Similar programmes are continuing in many western countries, some more than 100 years old, with the Christmas Bird Count in the US running since 1900.
These bird monitoring acts as an early warning system to initiate remedial measures to save species from extinction before it is too late, he said referring to the critically-endangered status of the vulture, which was once common in India, and proper monitoring could have checked its decline.
Dilawar said that citizens can register and spend 15 minutes daily to monitor the 18 birds for the project from their homes, windows or any other location and make notings and enter their data daily, weekly or monthly or annually.

How to create Incoming Webhooks?
To set up notifications to be sent to the Microsoft Teams channel using 1-way integration you have to generate an Incoming Webhook URL for a particular Microsoft Teams channel.
Generate Incoming webhook URL
To generate an Incoming webhook in Microsoft Teams, follow these steps:
 1. Open Microsoft Teams and navigate to the channel where you want to add the Incoming webhook.
 2. Click on the three dots (...) next to the channel's name and select Connectors from the dropdown menu.
 1. If you use the updated version of Microsoft Teams you should go to Manage channel section and click on Edit next to Connectors.
 image-20240130-170950.png
 3. In the Connectors window, search for "Incoming Webhook" and click on it.
 4. Click on the Configure button to add a new Incoming Webhook URL.
 5. Give your webhook a name and, optionally, upload an icon for it.
 6. Click on the Create button to create the incoming webhook.
 7. Copy the webhook URL that is generated. This URL is unique to your webhook and will be used to send messages to a particular channel.
 8. Click on the Done button to finish creating the incoming webhook.
In case the connector wasn't added to the particular channel before instead of the button Configure you will see the button Add. Add the connector to the channel and repeat all the steps from points 4-8.
Once Incoming Webhook URL is generated, you can:
 - insert it straight into Where to notify section (notification rule creation modal window) to use 1-way integration.
 - save it for other team members on the Managed URLs tab on the Global Configuration page (only for Jira admins)
Managed Webhook URLs
With Webhook URLs management, you can configure named Microsoft Teams Incoming Webhook URLs and optionally restrict them to particular Jira projects.
Please note, the Webhook URLs management is available only for Jira administrators.
Managed URLs are useful for several reasons:
 - simplified Webhook URL creation;
 - you can identify URLs by name, which provides much more flexibility to administer;
 - restrictions by the Jira project enable your project admins to use them without asking for a new URL.
For instance, you can create a URL for the Customer Success team and permit them to use it only by the Customer Success Jira project. It means that during the notification rule creation in Where to notify section this URL will be avaible only for Customer Success project.
To create a new Managed Url follow these steps:
 1. On the global navigation menu click on Apps and select Manage Apps section.
 2. Find our app in Manage apps section or Microsoft Teams section in the left-hand sidebar.
 3. Click on Settings or Configure button to navigate to Global Configuration page.
 4. On the Global configuration page go to Managed URLs tab.
 5. Click on Create URL button.
 6. Insert the Incoming Webhook URL you generated (see the instruction above) and indicate the rest parameters.
 7. Click on Save. To use this Webhook URL you need to switch on the toggle Use Managed URL and select the URL you need from the dropdown below.
Important: The restriction by project for a particular Incoming Webhook URL works only on project level. On Global level Jira admin can use all created Webhook URLs.

Question: If M is a spin manifold. Condider the dirac operator on a spinor bundle. Can the eigenvalue of this operater tend to negative infinity? If it can, can we choose a riemann matrix such that under this matrix, the eigenvalue of dirac operator does not tend to negative infinity??

Given any first order, graded, self-adjoint, elliptic operator on a manifold the spectrum is unbounded in both the positive and negative directions. There are probably elementary ways to see this, but I'll give an argument which is overly sophisticated but a bit more quantitative.
Given $D$ as above, consider the eta function associated to $D$:
$$\eta(s) = \sum_{\lambda} sign(\lambda) |\lambda|^{-s}$$
(the sum ranges over the eigenvalues of $D$)
By a variation on Weyl's asymptotic formula for the eigenvalues of the Laplacian together with some basic complex analysis, this function extends to a meromorphic function on the complex plane. It is a very deep topological fact that the eta function is actually bounded at $0$; in the case of Dirac-type operators this follows from the sort of heat kernel analysis used in the local proof of the Atiyah-Singer index theorem, and for general elliptic operators this follows from the Dirac case together with some cobordism theory.
In any event, $\eta(0)$ can be regarded as a sort of "renormalized difference" between the number of positive eigenvalues and the number of negative eigenvalues, and the fact that it is bounded means that there are infinitely many positive and negative eigenvalues.
As I said above this machinery is probably overkill as far as your actual question is concerned, but it proves something stronger: it makes precise the assertion that the cardinality of the positive part of the spectrum agrees with the cardinality of the negative part "up to a finite error".

"There are probably elementary ways". I think the following should work: It suffices to show that the Rayleigh quotient $\langle \phi, D\phi\rangle/|\phi|^2$ is doubly unbounded. Take $\phi$ to be supported in a ball where $D$ is well approximated by a constant coefficient operator. In a much smaller domain, take $\phi$ to be an eigenvector $\psi$ for the latter operator thought of as an operator with periodic boundary condition (i.e. an operator on a torus). – Tim Perutz Oct 29 '11 at 22:56
In the larger ball, define $\phi$ by cutting off $\psi$, but slowly, so that the behaviour of $\psi$ dominates. This reduces the problem to the case of constant coefficient operators over the torus, for which Fourier series are available. – Tim Perutz Oct 29 '11 at 22:57
BTW, a good account of these facts about the eta function is given by Ken Richardson in his note "Introduction to the eta invariant" ncatlab.org/nlab/show/eta+invariant#Richardson – Urs Schreiber Aug 27 at 18:52
Can the eigenvalue of this operater tend to negative infinity?
Yes -- actually this question is closely tied to the physical origins of the Dirac operator. Very roughly speaking negative eigenvalues correspond to negative-energy eigenstates; the Dirac equation predicts that particles with positive energy (e.g. electrons, which can have arbitrarily large positive energy) there is an antiparticle "twin" with negative energy (positrons in this case).
For instance, if $M$ is the unit sphere in $\mathbb{R}^3$ then Dirac eigenfunctions give you the angular part of the electron wave function; the corresponding eigenvalues are simply all the integers $n \in \mathbb{Z}$ which show up with multiplicity $n+1$.

Wolverton is responsible for the data analysis and subsequent feasibility study, concept study, concept report and design of solutions for safety issues identified across Districts 3 and 6 in Georgia. To date, our team has been assigned several traffic studies to identify safety improvements at key intersections in both Districts.
We work with GDOT to analyze the site for any solutions to safety issues within the project limits, including removal of traffic signal, adding protected left-turn phase, sight distance improvements, better signage, etc. Proposed safety improvements include innovative intersection designs such as roundabouts, CFIs and others.
Each project is analyzed using an Intersection Control Evaluation (ICE) tool to determine the best method for operation. The team then completes a feasibility study to further study the impacts on implementing these recommendations, and, if warranted, we complete concept drawings, cost estimates and a concept report for the project before moving into preliminary and final plans.


and optimizations that detect that the property is being overwritten by another animation and does something smart about it, but this is how we can think of the work being done by the render server.
model value implicit explicit composite
A breakdown of how the render server applies the implicit and explicit animations when the model is updated first
For the case where the model is updated last, the implicit animation is added after the explicit animation. This means that in the beginning of the animation, the explicit animation sets its intermediate values and the implicit animation overwrites it with its own intermediate values. When the implicit animation finishes and is removed, the explicit animation is still just in the beginning, so for the next frame the property will be perceived as returning to an earlier value but it is actually showing the correct value for the explicit animation for that time. Just as before, when it's only the explicit animation left, it runs until completion at which point we are left seeing the model values. This animation doesn't look right at all.
model value explicit implicit composite
So, which of the two is it best practice to update the model value?
It's actually a trick question because the answer it both neither place and either place. The best practice is actually to do the same thing as UIView is doing and disable the implicit animation. If we do that, then it doesn't matter it we update the model before or after. It's just personal preference. That said: I still like to update the model first:
var myAnimation = CABasicAnimation(keyPath: "position.x")
myAnimation.fromValue = oldValue // still the current model value
// if you want to be explicit about the toValue you can set it here
myAnimation.duration = 1.0
view.layer.position.x = newValue // now there is a new model value
view.layer.addAnimation(myAnimation, forKey: "move along X")
As pointed out on twitter, another way to achieve the correct behavior is to update the model first and use the key path as the key when adding the explicit animation. This works because the implicit animations already uses the key paths when added to the layer, meaning that the explicit animation cancel out the implicit animation.
I still prefer to use a transaction because I think that it's clearer what it does. The task is to disable the implicit animation and the transaction does that directly by disabling the actions. To me, that is pretty much self documenting code.
Additive animations
It can seem odd to allow multiple animations for the same key path when it results in either strange animations or calculated values that are never seen, but it is actually what enables one of the more flexible and powerful features of CAAnimations: "additive" animations. Instead of overwriting the value in the render tree, an additive animation adds to the value. It wouldn't make sense to configure this one animation to be additive and change the model value at the same time. The model would update to its new value right away and the additive animation would add to that:
model value additive composite
An illustration of what would happen if the explicit animation from before was made additive
Instead we would use a regular animation to perform the transition between the old and new values and then use additive animations to make changes to the animation as it is happening. This can be used to create very dynamic animations and even add to an ongoing animation. For example, to make a small deviation from the straight path between two points:
model value regular additive composite
An illustration of how an additive animation adds to another animation
let deviate = CABasicAnimation(keyPath: "position.y")
deviate.additive = true
deviate.toValue = 10
deviate.fromValue = 0
deviate.duration = 0.25
deviate.autoreverses = true
deviate.timingFunction = CAMediaTimingFunction(name: "easeInEaseOut")
deviate.beginTime = CACurrentMediaTime() + 0.25
This little trick can be used to acknowledge a users touch during an ongoing animation since it can be added to the running animation at any point.
Multiple additive animations can also be used together to create really complex animations that would be very difficult to with just a single animation:
model value regular additive additive composite additive
A complex animation created using multiple additive animations
For example, two keyframe animations with different paths can be combined to create an animation where one path loops around the other path, in this case a circle that loops around a heart:
A repeating animation of one path (a circle) looping while following another path (a heart)
There really isn't much code to such a complex animation but you can imagine how hard it would be to generate a single path for the same type of animation.
let followHeartShape = CAKeyframeAnimation(keyPath: "position")
followHeartShape.additive = true
followHeartShape.path = heartPath
followHeartShape.duration = 5
followHeartShape.repeatCount = HUGE
followHeartShape.calculationMode = "paced"
let circleAround = CAKeyframeAnimation(keyPath: "position")
circleAround.additive = true
circleAround.path = circlePath
circleAround.duration = 0.275
circleAround.repeatCount = HUGE
circleAround.calculationMode = "paced"
layer.addAnimation(followHeartShape, forKey: "follow a heart shape")
layer.addAnimation(circleAround, forKey: "loop around")
For some inexplicable reason I completely missed Session 236: "Building Interruptible and Responsive Interactions" (from WWDC 2014) when I first wrote this post. It also talks about additive animations and the role they play in iOS 8 to create UIKit animations that can seamlessly transition from one to the other. As mentioned in that video, the very same technique can be applied to any CAAnimation.
This works by updating the model value and creating additive animations that animate to zero from minus the difference between the new and old values. The result of one such animation looks just like the regular, smooth transition. When the animation starts out, the model value is updated by full change is subtracted meaning that the rendered value is back at its old value. As the animation progresses the subtracted value becomes smaller and smaller until it becomes zero when the animation finishes and the rendered value is the new model value.
What makes this so powerful is that if the model value changes during the animation, the first animation can continue until it's contribution becomes zero while a new, similarly constructed additive animation is added on top of it. During the time that both animations are running, the contribution from the first animation becomes smaller and smaller while the contribution from the second animation becomes larger and larger. This makes it look like the animation is adjusting it's target on the fly while maintaing momentum, taking some time to fully change its course.

A breakdown of how additive animations can be used to seamlessly transition from one animation to the other
The result is pretty astonishing and a great example of the kind of interaction that can be created using additive animations.
Note: the animations in the above illustration (and all the other illustrations) are linear. Visualizing easing would have made the illustrations more complex, but without easing there will be a noticeable change in velocity when transitioning between animations. The animations below uses easing to show what the real end result looks like.
The difference between regular and additive animations for transitioning between animations.
The difference between regular and additive animations for transitioning between animations.
Perhaps what's most impressive is how little code it takes. We calculate the difference between the old and new value and use the negative difference as the from values (in this case I calculated the negative difference directly by subtracting the new value from the old value) and the use "zero" as the to value.
let animation = CABasicAnimation(keyPath: "position")
animation.additive = true // an additive animation
let negativeDifference = CGPoint(
 x: layer.position.x - touchPoint.x,
 y: layer.position.y - touchPoint.y
// from "-(new-old)" to "zero" (additive)
animation.fromValue = NSValue(CGPoint: negativeDifference)
animation.toValue = NSValue(CGPoint: CGPointZero)
animation.duration = 1.5
animation.timingFunction = CAMediaTimingFunction(name: "easeInEaseOut")
I made a small sample project that can be downloaded from here if you want to compare the interaction for yourself.
Additive animations isn't used all that often but can be a great tool both for rich interaction and complex animations. The new playgrounds in Xcode 6 is a great way of experimenting with additive animations. Until XCPlayground becomes available for iOS, you can create an OS X playground and use XCPShowView() to display a live preview of the animating view. Note that views behave differently on iOS and OS X, but stand alone layers work the same.
If you want to use the playground with heart and circle animations as a starting point, it can be downloaded from here.
Just because I couldn't resists doing so, this is a visualization of what happens when an animation isn't removed upon completion. That is one reason to avoid removedOnCompletion in the common case but the main reason is still that it the model value no longer reflects what't on screen, something that can lead to many strange bugs:

What Causes Hot Tub Foam?
Foam can often be mistaken as friendly hot tub bubbles, but in reality, it is associated with the water's cleanliness. Have you ever looked at your foam in your hot tub and wondered what could be causing it? Hot tub foam is a common experience with all hot tub owners and can be caused by several factors. Although not a serious problem, excess foam can become an unpleasant sight
From shampoos and body oils, to detergent residue and soaps, there could be plenty of resources as to why your hot tub water looks foamy. The appearance of foam in your hot tub's water may also be varied. Sometimes it is patches of foam here and there, and other times the water might look too milky. Read on to know what could be causing the water in your hot tub to become foamy and what you can do about it!
The Chemistry Behind Foamy Water
In order to understand what are the causes of foamy water, it is essential to know what is the science behind this foam. Foam is caused by the build-up of Total Dissolved Solids or TDS. These TDS float at the surface of the water in a hot tub along with the air bubbles created by either the blowers or the jets of the hot tub. Thus, the foam is basically TDS plus air bubbles floating on the surface of the hot tub's water.
In short, the foam is the unwanted contaminants in the water that not dissolvable and thus come up to the surface of the water along with air bubbles. These solids can enter the water from various sources and can remain partially dissolved until the water is cleared. In a span of a week or month, the water can get saturated from the accumulated solids and as a result, the water starts to create foam on the surface. When the water reaches its true saturation point, it starts becoming milky or cloudy in appearance.
Causes of Foamy Water
Amongst the various factors that contribute towards foamy water, a chemical imbalance in the hot tub's water is the most commonly found trigger. When chemicals in the water are disproportional, excess foam is produced. In the long run, a chemical imbalance can also lead to discoloration of the hot tub's surface.
Another cause of foamy water is low calcium levels. When the amount of calcium in a hot tub's water is low, the surface tension decreases thus leading to the lathering of water. Low calcium hardness can also cause damage to the different parts of the hot tub.
Foamy water can also be caused due to beauty products that are applied externally on hair, body, and face. Products like body lotions, body oils, hair serums, hair oil, makeup, etc. can contaminate the water and lead to the formation of foam. These chemicals tend to build up and accumulate in the water until it is saturated and thus lead to the production of foam in the water.
There are several other factors that contribute to the formation of foam. The body secretes sweat and sebum which can mix in the hot tub water while you are soaking. Sometimes our clothes can also contribute to foam production. Soap residue and fabric softener from clothes have a high chance of getting mixed in the hot tub's water. Another contributor to foam is sunscreen. Even though these factors are microscopic in nature, they have the capacity to saturate the water and produce foam on the surface of the hot tub over time.
Getting Rid of Existing Foam
Once you find that the foam in your hot tub has reached a point where it has to be treated, start by assessing the quality of the water. TDS, pH levels, sanitizer levels, acidity, alkalinity are the various factors that need to be first assessed. While the best solution to get rid of foam is to empty the hot tub and fill in new water, there are also many products available in the market that can help dissolve the foam.
Clarifiers work well by clumping the foam together so that it can be filtered away. Sanitizing the water with excess chlorine, also called as a shock, is a popular method of ridding off foam. It is important to make sure to run the jets with the hot tub cover half open while performing a shock so that the excess gas can get released quickly. Anti-foam or de-foamer chemicals like BioGuard Anti-foam help in dissolving the foam.
The most commonly used remedy is to scoop out the foam from the hot tub manually. Although this is not a very practical solution, it does help in temporarily fixing the issue. If after trying all these methods you still notice a significant amount of foam in the hot tub, the best thing you could do is empty the tub and refill it, but with anti-foaming agents this time.
Preventing Foam From Reoccuring
An easy way of preventing foam from accumulating is to shower before you enter the hot tub. This will ensure that any sweat, sebum, body care products, etc. get rinsed off. Rinsing your hair is also a good way of preventing hair care products from entering the pool. Rinsing swimsuits and bathing clothes before you wear them to the hot tub is a good way of avoiding the fabric softener or detergent residues from building up in your hot tub.
If you really wish to spend ample time in the hot tub, make sure you are using a shower cap or baseball cap to avoid hair care products from entering the water. Do not invest in cheap hot tub chemicals as they don't help in the maintenance of the quality of the water. Avoid taking drinks to the hot tub as there are high chances of them getting spilled in the water. It is also best to minimize the times of eating at the hot tub by making use of floating bars.
Drain and clean the hot tub every there to four months. This will ensure that no dirt or debris gets accumulated. It is also equally important to clean the filters thoroughly as the filter system helps in filtering out excess dirt from the water. Alternatively, you can add scumballs in the cartridge of the filter and it will suck in all the dirt and debris that could create foam in the water.
Keep a strict maintenance schedule for the hot tub. This should include changing the water, replacing the filter, checking pH level, checking calcium hardness, checking chlorine levels, assessing sanitizer levels, etc. Regularly shocking the water also helps in clearing away dirt and dust. Allow the water to breathe by removing hot tub cover occasionally.
In conclusion, prevention is always better than cure, even in the matter of foamy hot tub water. Foamy water is not only an issue about water quality, but it also indicates the build-up of bacteria. It is very easy to prevent foam from producing in the first place by simple precautions like balancing the water chemistry and using shock treatment regularly. A proper maintenance schedule will ensure a foam-free hot tub experience for longer periods of time.

- The possibility of using yeast from alcohol distilleries as a source of nutrients in soil was investigated. The following treatments were used: no fertilization (control), 0.5% (w/w) yeast, 1% (w/w) yeast, and NPK. The decomposition of yeast was monitored for 90 days in two soils. The CO, production and the microbial biomass were increased by art average of 1- to 3-fold by yeast incorporation compared to control. Protease activity also was enhanced 3- to 8-fold in the soils supplemented with yeast compared to control. The phosphatase activities were higher than control only during the first days. While nitrate contents increased in all treatments compared to control, available P only increased in the soils amended with 1%, yeast or NPK by 45-119% and 309-489%, respectively. These results indicate that there exists an excellent potential for the use of yeast in the soil as a source of nitrate and available P for plant nutrition. (C) 2003 Elsevier Ltd.

Diminutive/affectionate form for the name Anatole?
Hi everyone!
I'm looking for a dimunitive/affectionate form for the name Anatole which would be used in a French or French-speaking family (or by a French/French-speaking lover and/or close friend). If different diminutives exist and they have different conotations (like one is something that could be used by friends but another is too "fluffly" and would most likely only be used by a parent) please let me know that sort of information too.
I've tried to google this, but all I'm getting is other versions of the name (like alternate spellings, eg: Anatol, or from other languages, eg; Anatoliy, which is the Russian version of this name). But I'm interested specifically in a diminutive/affectionate form.
(Also, I don't know if this matters, but the time period the story is set in is early 1800s. It seems to me that there isn't a lot of difference between how diminutives function now versus how they functioned then, just language convention wise, but I'm not sure? I know with a few Russian names there are minor differences (eg: for the name Dmitri, the diminutive Mitya was most common at that time, whereas now Dima is more common), so I thought I would mention this. If you know of a difference in which diminutives were used then v now, I'd be interested in that information too.)
Thank you!

The Impulsive/Premeditated Aggression Scale (IPAS) is a 30-item self-report questionnaire. Half of the items describe impulsive aggression and half the items describe premeditated aggression. Aggressive behavior has traditionally been classified into two distinct subtypes, impulsive or premeditated. Impulsive aggression is defined as a hair-trigger aggressive response to provocation with loss of behavioral control. Premeditated aggression is defined as a planned or conscious aggressive act, not spontaneous or related to an agitated state. The IPAS is designed to characterize aggressive behavior as predominately impulsive or predominately premeditated in nature. Those subjects who clustered on the impulsive factor showed a broad range of emotional and cognitive impairments; those who clustered on the premeditated factor showed a greater inclination for aggression and antisocial behavior.

How frequently can male dogs breed?
How many times can a male dog mate in a day?
One acceptable and recommended thing for male dogs is that they mate with female dogs at most twice a day. But, for the male dogs, if you give them a chance to do this more than twice, they won't hesitate. There are no rules on how frequently in a day male dogs should mate; some males can go up to ten times or more.

A normal male dog can ejaculate every two to five days and maintain their daily sperm output. However, frequent ejaculation influences the quantity and quality of the dog's semen. To ensure good quality sperm, semen should be collected no more than every other day on a regular basis.
How many times can you breed a dog in a year?
It's possible for a female dog to have a maximum of three litters a year. Female dogs can go into heat around the age of six to 12 months and do not go into menopause. Assuming a dog lives to the average age of 11, a dog could have up to 30 litters.

Consider the sentence:
You didn't leave the dog in the car, did you?
In spoken English, this statement may be spoken with a rising intonation or a falling one. If the former, it suggests that leaving the dog in the car is a bad thing, and might even suggest incredulity and consternation on the part of the person asking.
In the latter case, when the sentence ends with a falling intonation, the speaker probably believes that the dog should have been left in the car, and that the person being addressed fell short. It amounts to an accusation.
Now, given that question tags are always questions, it seems they ought to be punctuated with a question mark. But in written form, especially dialogue, it feels to me that question tags meant to be spoken with a falling intonation might get by with just a period:
You didn't leave the dog in the car, did you.
I've tried Web searches but haven't gotten close to a set of search terms that point me toward an appropriate source. Anybody know of a definitive answer to this question?
Further Reflection
One of the reasons I ask this is that any declarative statement may be changed into a question by means of a rising intonation at the end.
You left the dog in the car.
becomes a question if your voice modulates upward at the end. In written English, it is customary to show that by means of a question mark:
You left the dog in the car?
I include this information because _USER_ asserts that "punctuation may not be used to differentiate [someone's] two intonations." Yet clearly there are cases in which punctuation is used in precisely that way (though in this case involving the opposite modulation from what I'm suggesting). So I wonder if it might not be possible to move the needle in the other direction.
If not, why not?
Note: I almost accepted my own answer to this question, but retracted it. If someone comes up with a better one I'll certainly consider awarding that one the checkmark. I think this question touches on an important concept, despite the scant attention it has received.

Traditional punctuation prescribes a question mark even if the tone does not go up; it is not a direct representation of tone, but of the grammatical status of the sentence (direct question or no). See Fowler. – Cerberus Jun 15 '12 at 15:24

_USER_: They are not even remotely similar, except that both concern question tags. – Robusto Jun 15 '12 at 15:48
I might punctuate #2 like this: "You didn't leave the dog in the car – did you." (BTW, your question has me wondering if you should have ended the title of your question with a question mark... A question mark is always required – isn't it.) – J.R. Jun 15 '12 at 15:50

The Chicago Manual of Style, 15th Edition (2003) has this entry under "Exclamation Point":
6.77 Exclamation rather than question. A question that is essentially an exclamation usually ends with an exclamation point.
How could you possibly believe that!
When will I ever learn!
If we take this guidance seriously, it seems to me, then for like reasons we ought to find it acceptable for a question that is essentially a statement to end with a period.
Consider this lyric from Lisa Germano's song "Bad Attitude": "But if life was easy, you wouldn't learn anything, now would you." I certainly wouldn't criticize a writer for complying with the standard approach of ending that statement with a question mark—and in fact I believe that Ms. Germano does use that punctuation. Nevertheless, given that her more-speaking-than-singing voice drops by more than an octave between "now" and "would you," I wouldn't think it misleading to end the sentence with a period.
In addition, Chicago 15 has an entry under "Question Mark" for what it calls "courtesy questions":
6.74 Courtesy question. A request courteously disguised as a question does not require a question mark.
Would you kindly respond by March 1.
Will the audience please rise.
That gives us two instances in which a widely influential U.S. reference work endorses using punctuation other than a question mark to end a phrase otherwise structured as a question.
I tend to agree with Robusto that strict adherence to the rule requiring all statements that are laid out in a form that would normally identify them as questions to end in question marks prevents writers from indicating, as they otherwise might, whether the intonation of the speaker's voice is rising or falling. The bad aspect of any widespread effort to differentiate intonation by punctuation is that it invites countless instances where authors choose punctuation mismatched to their intended intonation, and readers—newly alert for clues to intonation in the punctuation—consequently misinterpret the sentence.

Good answer. +1. – Robusto Feb 20 '13 at 12:50
By "mismatched to their intention," I mean "mismatched to their intended intonation." – Sven Yargs Feb 21 '13 at 2:49
I edited that for you, but you could have done that yourself by clicking the edit link underneath your text. – Robusto Feb 21 '13 at 3:02
I basically agree with FumbleFingers, I say you should always use a question mark, but you can't derive the intonation from the text so written.
But why would you restrict yourself when using the written word? Something like:
"You didn't leave the dog in the car, did you?", she asked incredulously...
or a slight rephrasal:
"You left the dog in the car, didn't you?", she asked incredulously...
would provide further context, which would then inform the reader regarding intonation (were they to read the written text aloud for instance).
Short answer - the written word requires more context, what stops you from providing it?

I won't downvote, because it's a sensible answer, but I must disagree. You are sacrificing economy of expression because you can't bring yourself to punctuate sensibly. – Pitarou Feb 20 '13 at 4:08
Sorry, but in what way can you punctuate this to unambiguously delineate all the possible meanings spoken inflection could convey? I don't think it is possible - but why would you try? Punctuation isn't the correct tool for the job in this case. – Kyudos Feb 20 '13 at 21:09
Of course punctuation can't convey EVERY nuance, but in the case of tag questions, there are clearly two distinct types, with distinct meanings and distinct intonations, and it seems that punctuation is the perfect tool for distinguishing them. – Pitarou Feb 21 '13 at 12:41
One punctuation mark is enough, and the comma after the quotation mark is incorrect. Also, incredulously is spelled wrong. – shipr Feb 21 '13 at 22:13
There are more than two types of tag questions; punctuation could never represent them all. And by the way, regarding the question mark followed by a comma, we already have an "interrobang" (question mark combined with exclamation point) although it is almost never used. Why not create a combination question mark and comma (replacing the period under the squiggle)? I think it would be wonderfully useful, and graphically easy to understand, in exactly such cases as the example sentences Kyudos gives here. – John M. Landsberg Feb 24 '13 at 8:45
I think there's no way for punctuation alone to represent with absolute fidelity what the speaker's tone, intention, and exact meaning are in such a case. That would be expecting far too much of a simple graphical dot or squiggle.
The writer must decide just how important it is to convey one and only one particular precise tone and intention. The more important it is to convey the exact intended meaning, the more important it becomes to use contextual clues to get that meaning across to the reader.
Creative writing gives you license to describe the setting, the demeanor of the participants in the scene, the exact circumstances surrounding the statement at the moment it is spoken, and much more, in order to give a clear sense of how the statement and its tag question are being delivered. You could even explicitly describe the tone of the person's voice if necessary.
So, no, you are not required to use a question mark, but you are free to utilize all a writer's tools to make the sentence work the way you want it to.

I really hate it when people downvote without explaining why. – Pitarou Feb 24 '13 at 23:10
+1 You basically said what I was thinking, John - that with all the writing tools at one's disposal, why box the dialog into needing to depend on the question mark. However, if one is reporting, not creating, it becomes slightly more difficult since the actual quoted words are limited to what was


4 Practices For Solving NBC Audio Problems
nbc audio problems
nbc audio problems
NBC is one of the most preferred choices among people who like access to an endless range of content. This is because the NBC TV network offers a promising range of TV shows and movies. The best thing about this TV network is that it allows the users to schedule the downloading of the desired content. However, there are various NBC audio problems associated with this TV network, and with this article, we will mention the common problems as well as the suitable solutions.
NBC Audio Problems
1. No Audio
It is needless to say that proper audio function is important to enjoy the video content, and when the video starts playing without any audio playback, it's obvious that you have to check the settings and signals. First of all, you must test other videos on the NBC TV network to determine if the problem is only on one channel or all channels. Keep in mind that if all channels have no audio issue, it's something wrong with the service. On the other hand, if only one channel has no audio problem, there are higher chances that the channel has some signal issues, which can be resolved by calling the channel provider.
The second solution is to check the audio settings. This is because incorrectly set audio settings will mean that you won't be able to hear the audio. If you are using the smart TV, you need to open the settings and make sure the audio is set to normal or stereo. On the other hand, if you are watching NBC TV network on a computer or smartphone and there is no audio, you have to check the device's volume to make sure it is not set too low.
2. Distorted Audio Sound
The distorted audio sound means that the videos will have audio running in the background, but there will be distortions – the audio will be too fast, too slow, or the audio will be missing. In the majority of cases, this issue is caused by the backend server issue. To begin with, you should call the NBC TV network to make sure their server is not down. This is because when the server is down, there will be an issue with the signal reception. Similarly, when the signals aren't received properly, the audio won't work on point. All in all, if there is a server issue, you will only have to wait because only the network providers can fix this problem.
Secondly, you must check the cables. In the majority of cases, people think that audio and sound issues aren't caused by cables, but HDMI cables are often at fault. You have to start by inspecting the HDMI cables and see if the cables have been damaged. If that's the case, you will need to replace your HDMI cables. On the other hand, if the cables are not damaged, you must ensure that they are plugged in tightly into the respective jacks.
3. Out-Of-Sync Audio & Video
The out-of-sync audio and video means that the audio won't play with the video; there will be disruptions in the flow of audio. For the most part, the problem is caused by signal disruption. For this purpose, you have to check the receiver and dish and make sure there are no hindrances around these units. For instance, you have to check the dish and make sure there are no hindrances around it, such as bushes and trees.
When the dish is getting proper signals and it's sending these signals to the receiver, the audio and video sync will be optimized. On the other hand, if the dish has been disturbed and you aren't able to handle it on your own, you have to call NBC TV network's technical team because they will be able to realign the dish and set up the receiver again to make sure everything works in unison.
4. Too High Or Low Volume
When the volume of your content is too high or too low, it is usually caused by your volume settings. You need to start by checking the volume control of your device and make sure it's not set too high or low. Once you regulate the volume, you will be able to get the desired level of volume. However, if the device's volume is all right, you can call customer support for help.

Life on a Colonial New England Farm
Making a Class Presentation
Life on a farm in colonial New England was a real challenge. Using the library or the Internet, find accounts of how New England farm families lived. Then design a multimedia presentation about a typical New England farmer and his family. Be sure to include the social and economic contributions of women in your presentation.
- Create a map of the town in which the farmer and his family lived.
- Dress up like a farmer to discuss the challenges of New England agriculture.
- Create a chart that lists the differences between your family's lifestyle and the colonial family's.

Permanent Marker Pen or indelible marker
A permanent marker or indelible marker is a type of marker pen that is used to create permanent writing on an object. In general, the ink comprises a main carrier solvent, a glyceride, a pyrrolidone, a resin and a colorant, making it waterproof. It is capable of writing on a variety of surfaces from paper to metal to stone. They come in a variety of tip sizes (ultra fine to wide), shapes (chisel point, bullet tip, and wide bristle), and colors (metallic, or ultraviolet reactive). Like spray paint, these markers contain volatile organic compounds which evaporate to dry the ink. Permanent marker is another name for "waterproof" marker. They have a potential for abuse as a recreational drug.
Permanent Marker Pen
These markers are generally used on hard, non-porous surfaces because instead of staining they form a surface layer that can be removed by high-pressure cleaning or paint thinners and organic solvents such as acetone, xylene, or toluene. Isopropyl alcohol, ethanol, and ethyl acetate are preferred cleaners when used indoors, as their fumes are much less hazardous than toluene and xylene, the main components of paint thinner, or longer-chain hydrocarbons found in mineral spirits. Other common non-polar solvents include benzene, turpentine and other terpenes (which constitute essential oils of many plants with strong scents), most others, chloroform and dichloromethane, hydrocarbon fuels, and diacetone alcohol, among many others. Note that most of these solvents are very flammable, and/or their concentrated vapors are harmful to health.
Some markers are designed to be long-lasting, for instance by having two inks, one specialized to resist solvents, and one specialized not to fade.These can be available in refillable form.
A permanent marker can also be removed by drawing over it with a dry erase marker on non-porous surfaces such as a whiteboard as dry erase markers also contain a non-polar solvent. Most dry-erase board cleaner solutions also contain effective organic solvents like 2-butoxyethanol to erase the pigment.


What's the Difference Between Sanding Screen and Sandpaper?
Sanding screen and sandpaper
Are you wondering about the differences between sanding screen and sandpaper? Have you been trying to decide which you should use on your next project? In this article, I'll share everything you need to know about these two sanding products.
Most people use sanding screens for rough shaping and sandpaper for finish work. However, this is just a general principle. Sandpaper and sanding screens have some overlap in the jobs they can perform.
Below, we explain the main differences between sanding screens and sandpaper.
Let's jump in!
Differences Between Sanding Screens and Sandpaper
To start, here's a rapid-fire list of the main differences between sandpaper and sanding screens.
In the sections below, we will explore each in more depth.
Some of the differences between sanding screens and sandpaper:
 - Sanding screens allow dust to pass through
 - Sanding screens are more durable
 - Sandpaper is for finish sanding
 - Sanding screens are for demolition sanding
 - Sanding screens are often used for drywall and flooring
 - Sandpaper is often used for furniture as it is more pliable
Okay, now that we've got a few of the basics covered. Let's explore each of these in more depth
What is a Sanding Screen?
A sanding screen is exactly what it sounds like, a screen used for sanding. The screen is made of a mixture of silicone and resin. This combination creates a durable product.
The sanding screen works like sandpaper, smoothing a rough surface. What's the advantage of sanding screens? There are two main things.
First, sanding screens are durable. This durability allows you to use sanding screens on rough walls or floors.
Second, the screen of the sandpaper allows the dust to pass through, preventing dust build-up. The clearing effect of the screens increases the efficiency and lifespan of the sanding screen.
When Should I Use a Sanding Screen?
The sanding screen is a useful product, but is it good for everything? Below, we list some of the best times to use a sanding screen (and when to avoid it).
Here are some of the best times to use a sanding screen instead of sandpaper:
 - Large projects: when you've got a lot of work to get done, the sanding screen is there to help. The durability and dust clearing capabilities of the sanding screen make it a great choice for large projects
 - Rough projects: if you're sanding down some rough drywall, or preparing an old floor for new tile, then the sanding screen can help.
Now, let's discuss some times to avoid the sanding screen:
 - Small, finish work: if you're trying to sand your kitchen table to a mirror shine, then traditional sandpaper will likely be the way to go.
 - Sanding rounded edges: for rounded edges, look into using a sanding sponge or regular sandpaper. Silicone carbine sanding screens are geared toward removing rough material.
 - Using them by hand: Since sanding screens are abrasive on both sides, they aren't ideal for sanding by hand. Attaching the sanding screen to a sanding handle or a power sander will yield the best results. If you need to sand something by hand, consider regular sandpaper.
Benefits of Sanding Screens
We touched on the benefits of sanding screens a little bit; however, let's cover a more inclusive list. Sanding screens have several benefits over regular sandpaper.
Here are a few:
 - Clog resistant
 - Durable
 - Double-sided
Let's look at these benefits in more depth.
Sanding Screens are Clog Resistant
When you're sanding a large surface, like drywall, you end up with a lot of dust and debris. Regular sandpaper manufacturers have made strides towards developing clog-resistant sandpaper. While these sandpaper advances have helped, it's still relatively easy to clog up normal sandpaper.
The sanding screen does a better job with high volume work. The screen portion of these sanders allows dust and debris to pass right through the sander.
While you'll still need to clear sanding screens, it's as simple as tapping them on the floor and getting back to work.
Sanding Screens are Durable
Regular sandpaper is prone to ripping, especially with rough work. Sanding screens are made from durable materials that resist tearing.
The durability of sanding screens makes them ideal for uneven surfaces, where you're sanding down some jagged bumps.
Sanding Screens are Double-Sided
Once you've worn down one side, flip the sanding screen over and get back to work. Regular sandpaper typically only has a single abrasive side. Once you've used it up, it's done.
How Long do Sanding Screens Last?
It's impossible to say how long your sanding screens will last. It all depends on how much you're using the sanding screen and if you're using the sanding screen properly.
Also, there are several ways you can restore both sandpaper and sanding screens. If you take the time to learn a few techniques to care for your sanding screen and sandpaper, you will get the most life out of your product.
Here are some ways to extend the life of your sandpaper and sanding screens:
 - Clean them: grab an abrasive sandpaper cleaner and use it to remove the gunk that builds up on your sandpaper.
 - Don't overuse: if you try to push sandpaper or sanding screens past what they can handle, you risk overheating (burns!) your project, leaving scratches, and tiring yourself out.
 - Don't use too much pressure: this goes along with overuse. Using too much pressure will cause more gunk to roll up under your sander.
 - You can use both sides: sanding screens are usually abrasive on both sides. Frequently switch the side you're using. Take time to clean the sanding screen intermittently.
How to Use a Sanding Screen
Using a sanding screen is not much different from using regular sandpaper. However, sanding is more difficult than many people anticipate. So, it's important to avoid overlooking critical steps.
Here are some guidelines to follow when using a sanding screen:
 1. Safety and dust control
 2. Clear large chunks with a scraper
 3. Start with low grits
 4. Use a steady pressure
 5. Mark your area
 6. Consider finishing with regular sandpaper
Let's look at these steps in more depth.
Safety and Dust Control for Sanding Screen
Before you begin sanding, always consider the safety risks. Wear safety goggles to protect from flying debris – this is especially true with power sanders. The minute you get something caught in your eye, you'll wish you had worn safety glasses.
Second, wear a mask, preferably one that seals your mouth and nose from dust. If you do a lot of sanding, the cumulative effects of inhaling dust can take a toll over the years.
Finally, try to set up a systematic dust removal process. If you can attach a vacuum directly to the sander, then you're doing great. At the bare minimum, have a box fan in the room sucking out the dust. (Also, you can look into wet sanding to reduce dust).
Clear Large Chunks with a Scraper
While sanding screens can remove substantial material, you still want your surface relatively smooth to begin with. If there are a bunch of bumps and chunks that you can safely remove with a scraper, you should get rid of them before sanding.
Though you could try to smooth out large chunks with a sanding screen, it will delay the project and increase erosion on your screen.
Start with Low Grits and Work your Way Up
If you start with a 40-grit sanding screen, you'll be able to knock down a lot more of those imperfections relatively quickly. However, you don't always want to start with an especially low grit.
Here's why.
Some surfaces, particularly drywall, could be susceptible to damage with low grits. Some people have reported deep gouges being caused by their sanding screens. (This may not be an issue for all situations).
It's worth trying out the sanding screen grit in an inconspicuous area before you use it on the whole surface.
Use Steady Pressure
Applying too much pressure to your sandpaper can damage a delicate surface. You want to apply some pressure to the sander; just enough to keep it on the path.
Just like when you use a saw, let the sanding screen do the work.
Mark Your Sanding Area
Don't accidentally sand an area that doesn't need to be sanded. Use tape, blankets, whatever you can to prevent damage to objects around you.
It's easy to start sanding and forget about everything. But, before you know it, you'll have sanded down a corner or scratched a smooth surface that didn't need to be sanded.
Finish Things Off With Regular Sandpaper or Sanding Sponge
Once you've used the sanding screen to knock down all the rough work, bring in the sanding sponge or sandpaper to make

Mortar Training Blended Learning Solution
CDS Defence Support was tasked to develop a blended learning solution for the Army Mortar Training School.
CDS was tasked to develop a Blended Learning Solution (BLS) for the Army Mortar Training School. The aim of the solution was to allow students in training to use mortars to practice and develop the skills associated with map reading, calculating bearings and judging distance based on the terrain's features.
Scanning the Landscape
The solution needed to be able to generate targets randomly at a variety of distances within a set training area. The students would then be required to manually scan the landscape to identify potential targets.
The students also needed to be able to use a service prismatic compass to acquire the target's direction.
After calculating the bearing, the students would have to accurately identify target locations on the map.
Making Corrections Based on a Missed Shot
The students would have to have the ability to make adjustments and re-engage the target an unlimited number of times.
Working closely with a number of SMEs, CDS interpreted the requirements and developed an application that delivered the required features whilst adding additional benefits at every stage.
Our BLS allows both the students and the instructors to have sight of the students' process of acquiring and engaging a target.
The students navigate round a geographically accurate virtual environment, based on a known training area, where a number of randomly generated targets appear at different distances. Once a target is identified, the student must use the skills learned in practical training to make the correct calculations and effectively engage the target.
Complex background algorithms accurately simulate, in real time, the characteristics of a mortar round's velocity, trajectory (fall of shot) and the time of flight. The student can then watch the round hit or miss the target and can make multiple corrections to re-adjust and re-engage until a Fire for Effect (FFE) order can be given.
This solution can also be integrated with Learning Management Systems.
Other optional features include:
- Encryption to allow for off-site use.
- Secure data link to record students' information including usage and strike rate.
- Auditable confirmation of training and competency.
A BLS has many advantages including:
- Students can be trained for multiple-operational scenarios and terrains prior to deployment.
- 24/7 access to training – no down-time due to adverse weather conditions or range day losses.
- Costs are reduced by negating the need for additional range time, ammunition and coaching/training staff.
- The application has cross-platform functionality and is able to run on Android, iOS and other similar operating systems.
- The Mortar Training can be digitally tailored to suit any combination of ammunition including illumination, smoke rounds and differing terrains.
In addition to the Mortar Training, CDS has also developed a 7.62mm General Purpose Machine Gun BLS. This unique tool presents the students with a geographically accurate virtual map, a protractor, a series of range tables and issue fire control data.
The students will identify and process the 8 figure grid reference number, the altitude above sea level, the bearing and distance and finally use this information to calculate the elevation adjustments required prior to engaging the target.

The Fowler Museum at UCLA presents a photographic exhibition by Gil Garcetti, with images that underscore the link between water and human health in West Africa. The photographs will be on display from September 9 through November 25, 2007. Acclaimed Ghanaian recording artist Rocky Dawuni will be performing on Sept. 9.
In 2001, Gil Garcetti traveled to West Africa for the first of several visits to the continent. Enthralled by the land and the people, Garcetti became deeply committed to raising awareness of and funds for safe water in the region. Thus was born 'Women, Water and Wells: Photographs of West Africa by Gil Garcetti,' a selection of sixty-two striking images on display at the Fowler Museum at UCLA from Sept. 9–Nov. 25, 2007. Garcetti's rich black-and-white photographs underscore the link between water and human health in West Africa, as well as the dramatic economic and public welfare successes that can be achieved when safe water is delivered to villages.
'Women, Water and Wells' reveals the challenges, hopes, and triumphs experienced by people throughout West Africa who are faced with the daily task of providing safe water for their families and communities. For men, the lack of safe drinking water and sanitation means that they are less productive as a result of more illness. But women and girls in West Africa bear more of the consequences of poor water, because they are typically charged with fetching water, trying to maintain household hygiene without easy means to do so, and caring for family members who fall sick from water-related diseases. The attendance of girls at school is also compromised by the amount of time that must be spent traveling long distances to obtain water for their families and by the lack of school water and sanitation facilities.
The exhibition commences with landscapes from rural Niger, Ghana, Mali, and Burkina Faso. The next section chronicles the important work of non-governmental organizations (NGOs) in the struggle to provide healthy drinking water and to eradicate a variety of diseases linked to unsafe water. Later sections show the joy that results from locating safe water sources and the ways that they benefit people through improved sanitation and health, enhanced educational and economical activities, and new agricultural possibilities.
Known for his long career as a prosecutor and a Los Angeles District Attorney, Garcetti has spent more than forty years as an urban photographer. His photography books Iron: Erecting the Walt Disney Concert Hall and Frozen Music have received critical praise in The New York Times, Los Angeles Times, The Oregonian, The Washington Post and other publications. In 2006 the Fowler Museum exhibited his work in 'Dance in Cuba: Photographs by Gil Garcetti.'
'Women, Water and Wells' is presented in conjunction with the publication of the forthcoming book, Water is Key (Edited by Peter Gleick, Pacific Institute; Published by Balcony Press) and made possible by the Conrad N. Hilton Foundation and Manus, the support group of the Fowler Museum at UCLA. Proceeds from the sales of Water is Key will benefit the Pacific Institute, an Oakland, California-based think tank dedicated to protecting the natural world, encouraging sustainable development, and improving global security. The Pacific Institute will use 100% of the money raised to benefit NGOs working on safe-water initiatives in West Africa.
'Women, Water and Wells: Photographs of West Africa by Gil Garcetti' will be on view in the Fowler Museum's Goldenberg Galleria.

Charity mergers include a range of legal and practical issues. There are very many charitable organisations, and both small and large have good reasons for considering combining to maximise their charitable impact.
Other charities may have reached the end of their useful life and want to manage the process of winding-up and dissolving the organisation.
Main issues to consider:
- Types of merger – the process will be determined by the outcome sought; a new charity may be formed to take the assets of two existing charities; one may dissolve and pass its assets to another; one charity may become a subsidiary of another
- Charitable objects – a charity must always act within the terms of its objects. It is important for charities that are combining to have compatible objects; if they differ, then the objects will need to be amended
- Role of the Charity Commission – where there are problems with a charity's ability to amend its objects, the Charity Commission can implement a cy-pres scheme. The Charity Commission can be involved in making a scheme, where a permanent endowment is held and the receiving charity is a company
- Issues to be considered – structural and practical issues need to be addressed - the constitution of the trustee board, membership, internal organisation and of course name
- Possible future liabilities – a charity receiving the assets and activities of another charity can take over liabilities; particular areas of concern may be VAT, the transfer of employees, and a defined benefit pension scheme with ongoing liabilities
- Register of charity mergers – introduced by the Charities Act 2006, this transfers gifts or legacies made to the merged charity to the successor charity.

Make Your Own USB Light
What you need
First: Flexible tube of approximately 30 cm. The length and color of tube depends on your personal taste, just make sure it is flexible enough as you will want to be able to accommodate your night light to your needs. There are several tubes that will do, even certain short coaxial (TV) cables if emptied from the wires can become night light tubes.
Second: One White Luminous LED. These come in different lumens (lumens is for LEDs what watts is for light bulbs. Just make sure you have a bright one. They are not expensive at all and they will outlast any light bulb. You can get other colors if you want, but make sure they are Luminous LEDs.
Third: You will need an old USB cable.
Fourth: A solder and soldering iron.
Environmental Safety: Prioritize your safety. Keep in mind that you are working with electricity, so keep your environment dry. This article is not responsible for your own interpretations of this article.
Start Building your Night Light
Step one: Cut the end of USB cable that does not go into the computer. Strip the insulation of the end.
Step two: Pass the cable through the flexible tube you have chosen.
Step three: Cut the cable to adjust to the length of Flexible tube. 30 cm should be good enough.
Step four: Solder the red and black USB wires to the LED's positive and negative end. Which is which? LEDs have two legs which are the cathode (-) and the anode (+). The longer leg is positive, and the shorter leg is the negative. So connect the red USB wire to the longer positive LED light, and the black USB wire to the short negative leg of the LED.
Step five: Now fix the cables inside the tube, and adjust the LEDS to one of its ends, and the USB to the other. You can use adapters to fix the LEDS in position or just black tape it with black tape.
Step six: Connect your new light to the computer.
You can use different LEDs, and different tubes. Keep in mind that you are using 5 volts.
