Python binding documentation
For a while, there has been a basic python binding for libvlc, that was used for streaming. A more complete (with a hopefully generic API that can be reused by other players) has been developped, based on the MediaControlAPI.
Sources are browsable from python binding and a code sample can be found in [1].
The vlc python module provides 2 main classes : MediaControl and Object.
vlc.Object provides a binding to the vlc object architecture. It allows to manipulate variables and configuration options, and explore the object hierrarchy. The vlcdebug.py script, located in the python bindings directory, wraps around the vlc.Object to provide an easier access to variables and objects (as illustrated in the code sample in [2]).
vlc.MediaControl implements the MediaControlAPI.
Methods taking positions as parameters expect a vlc.Position object, that provides a very flexible way to address absolute or relative positions, in a number of units (milliseconds, frames or bytes). For convenience, the python binding automatically converts integer positions into milliseconds vlc.Position objects.
Tips and tricks
Snapshot support
In order to get snapshot support, you have to activate the snapshot vout module through a clone video filter. The following code gives a way to achieve this :
 mc=vlc.MediaControl([ "--vout-filter", "clone" ])
 o.config_set("clone-vout-list", "default,snapshot")
 o.config_set("snapshot-width", 320)
 o.config_set("snapshot-height", 200)
Note that all config options could have been given on the command line, but this illustrates the use of the vlc.Object API.
There is a snapshot functionality built in the vlc core, associated to a hotkey. The MediaControlAPI could (should ?) use it, but
 - it did not exist at the time the extension was developped
 - the builtin snapshot functionality is oriented towards interactive use (hotkey activation, saving into a file) and should be revamped to take into accound a more programmatic use
 - the snapshot vout module holds a cache of reduced-size snapshots, that allow to take into account the reaction time of the user (around 200ms) and also to select the more appropriate snapshot from the cache.
Win32 initialization
If the vlc module was not compiled with the exact same prefix as the VLC installation (e.g. c:\\Program Files\\Videolan), then it cannot find itself the installation directory (stored in the registry Software\VideoLAN\VLC\Path), and the MediaControl instanciation will fail with a message like "Cannot find interface plugins".
The workaround consists in changing directory to the VLC installation directory before instanciating the MediaControl object.
 def get_registry_value (self, subkey, name):
 import _winreg
 value = None
 for hkey in _winreg.HKEY_LOCAL_MACHINE, _winreg.HKEY_CURRENT_USER:
 reg = _winreg.OpenKey(hkey, subkey)
 value, type_id = _winreg.QueryValueEx(reg, name)
 except _winreg.error:
 return value
 if vlcpath is None:
 print "Cannot locate VLC installation directory"

I need to show specifically using transfinite induction that given two well-ordered sets $\left(A,<_{1}\right)$ and $\left(B,<_{2}\right)$ there is only one isomorphism between them. To do this I want to show by induction that there is only one way to define the mapping and that is: $$\forall\, x\in A: \varphi\left(x\right)=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}x\right\} \right)\right)$$ Showing the base of the induction is no problem and the induction hypothesis would be that $$\forall\, y<_{1}x\,:\,\varphi\left(y\right)=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}y\right\} \right)\right)$$ My problem is that I can't seem to manage to use the hypothesis in order to prove the step. I've found a couple of ways to show this definition of the mapping is indeed necessary but none of those used the induction hypothesis. My plan was to mark $$c_{0}=\min\left(B\backslash\varphi\left(\left\{ a\in A\,:\, a<_{1}x\right\} \right)\right)$$ Using the fact $\varphi$ is surjective take $y\in A$ such that $\varphi\left(y\right)=c_{0}$ and show that it can't be that $y<_{1}x$ or $x<_{1}y$ and thus necessarily $y=x$. If someone could give me a way to show either one of these are false using the induction hypothesis it would solve my problem.
Thanks a lot!

What you want to show is that if $f\colon A\to B$ is an isomorphism of the given well-orders then $f=\varphi$.
Suppose that for $x\in A$ we have that $f\upharpoonright\{a\in A\mid a<_1 x\}=\varphi\upharpoonright\{a\in A\mid a<_1 x\}$. If $f(x)=\varphi(x)$ then we may continue the induction; otherwise $\varphi(x)

Dear readers, today we are going to talk about articulated dumpers, and more precisely we wish to give you a few tips on how to decide if an ADT suits your needs.
The worst mistake one can make is thinking that it doesn't matter whether to use a rigid or an articulated dumper (ADT) for transporting material. It's true that both have great load capacity, but each of them has some peculiar features and specifications. So, before choosing the vehicle to buy, identify the jobs that the ADT will have to carry out. And keep in mind the following points:
 1. Performing operations efficiently
ADTs have been designed to rapidly and safely move large quantities of material, minimizing the cost per ton of the transported material. Compared to rigid dumpers and other earthmoving vehicles, ADTs work well on soft terrain, and usually they are the first to be used in development stage at a site, when ground conditions are the least favorable ones. Choosing the right ADT can help you increase productivity and optimize haulage times.
 1. Choosing the right loading equipment
The question is: How can you increase productivity limiting the number of travels? Well, if you choose an ADT with the right loading equipment, so operators don't have to wait too long between one and another loading operation.
 1. Scheduled maintenance
We all know the cost of machine downtime, especially if due to equipment failure. The solution is to act before something happens: a special maintenance program is essential to keep your vehicle's performance unchanged and to ensure a longer life-cycle. So, before you make your decision about which ADT to buy, check that you can easily reach the engine compartment and the transmission. Regularly check:
 - the lubrication system to avoid failure due to lack of grease.
 - the tire pressure and tire wear.
 - the engine temperature to avoid damages and expensive repairs.
To prevent unpleasant accidents, you can address to companies that are specialized in scheduled maintenance, and observe also the other maintenance recommendations.
 1. Increasing versatility through more options and accessories
ADTs can be equipped with accessories to increase their potential. Some models have a heating kits that are essential in the coldest season, because it helps moving the engine exhaust through the exhaust body channels, avoiding possible freezing. The cold start-up kit and the heated rear-view mirrors are other useful options for ADTs employed in areas with particularly harsh winters.
 1. Choosing the right tire depending on the application
An important topic we often deal with. Always choose the tires that are suitable for both the equipment and the application. Never undervalue this aspect. By the way...
BKT recommends…
ADTs require extremely resistant and performing tires to support heavy loads. Earthmax SR 41 has been specifically designed for this task. It's a radial tire with an All Steel structure - ideal for all those operations that require traction and stability on particularly tough terrains.
This tire boasts a deep tread class E-4/L-4, which not only increases the tire life-cycle, but also provides maximum resistance to punctures and foreign matters.
Made of the BKT's latest-generation compounds, this tire is available in two different versions: with a cut resistant compound for terrains full of debris of various kind and with a standard compound for mixed applications requiring well-balanced performance.
In short, Earthmax SR 41 is the right tire for your articulated dumpers. Discover the available sizes on our website.

The Knotting of Equilateral Polygons in R-cubed
It was proved in that the knotting probability of a Gaussian random polygon goes to 1 as the length of the polygon goes to infinity. In this paper, we prove the same result for the equilateral random polygons in R3. More precisely, if EPn is an equilateral random polygon of n steps, then we have
P(EPn is knotted) > 1 - exp(-n∊)
provided that n is large enough, where ∊ is some positive constant.

Healthy planning policy and monitoring in Southwark and Lambeth
Built environment professionals are increasingly interested in the relationship between places and health. Many guidance documents are available to inform planning policy-makers of the importance of planning and health, yet there remains uncertainty about exactly 'what works' with regard to specific design and policy measures. In part, this has been explained by a lack of clear causal evidence to inform practice. However competing policy priorities and differing cultures of practice and evidence use across health and planning also play a role.
Despite these challenges, there is a growing desire to integrate design and planning measures which are known to support health and wellbeing into policies and projects. Planners want to know what has worked elsewhere and what evidence can be used to support local policies.
The research focused on three key health themes in Southwark and Lambeth which are widely relevant in the UK and internationally: social isolation, obesity (physical activity/healthy eating) and access to health services. Like many aspects of the urban environment's impact on health, there are many interconnections across these topic areas. The findings from academic research, consultation activities and policy examples often do not correspond to separate policy domains because of these overlaps. This is particularly notable with two of the focus areas for this review – social isolation and physical activity – which are both influenced by similar characteristics of the urban environment. In some ways, this is an advantage because policies can have multiple co-benefits. For example, increasing walkability through urban design may improve physical activity, increase social engagement and reduce local carbon emissions.
Planning policies alone will not address complex health issues like social isolation and obesity. As is often the case in urban planning and public health, officers will need to work across departments in the council and with other public and private stakeholders to integrate built environment solutions with other health promotion measures. Furthermore, solutions from one neighbourhood or research study may not be applicable more widely, depending on local context. There is great value in engaging local communities to explore their views of local problems and assets. This can ensure that policies and design measures respond to local needs, resulting in better outcomes.

Quick Answer: How Much Does It Cost To Install A Beam?
What happens if you remove a load bearing wall?
Removing a load bearing wall may create structural problems in a home, including sagging ceilings, unleveled floors, drywall cracks and sticking doors.
Removal of load bearing walls without properly supporting the load they're carrying may occasionally result in a structural collapse and even injury..
How much does it cost to put a support beam in a house?
A load-bearing support beam costs $5 to $20 per foot on average, or between $50 and $200 per foot installed. Support beam materials other than steel include engineered beams like LVL or Glulam, wood, and concrete. LVL beams cost $3 to $12 per foot, while wood beams run $5 to $20.
How do you size a load bearing beam?
Multiply the loading per square foot by the area in square feet of the surface which the beams will be supporting. Divide by the number of beams which will be installed to get the loading per beam.
How long can a support beam be?
Measure your total span between members and ensure that it is not greater than 60 feet. Because of transport limitations, the maximum standard length for manufactured beams is sixty feet.
How much does it cost for a load bearing beam?
Load-Bearing Support Beam Cost A load-bearing support beam costs between $3 and $35 per linear foot, with most homeowners spending $10 to $15 per linear foot. A laminated veneer lumber (LVL) beam costs $60 to $300 on average without installation.
Are ceiling beams expensive?
If you're building from scratch and want real beams, expect to pay an additional 10 to 15 percent more for your home. Real beams cost more than standard framing lumber, and because they're heavy and unwieldy, labor costs to install them are also higher.
What size beam do I need to span 30 feet?
Re: I-beam size 30′ span I would design this with the beam in the 24′ dimension. Most span tables will allow much more than 15′ for 2″ x 12″ joists of almost any species commonly used for construction. A 24′ beam can probably be a GluLam using standard joist hangers for the joists.
Should ceiling beams match floor?
If you have hardwood floors in your living room, it may be tempting to match your ceiling beams with them. … Matching the colors of your ceiling beams with the floor can help unify the visual impact of a space, but it might also create a flat, monotone effect in some cases as well.
How much does it cost to install a wood beam?
The national average materials cost to install decorative beams is $7.49 per linear foot, with a range between $6.72 to $8.26….Install Decorative Beams national average cost.cost to install decorative beamsNational Avg. Cost (materials & labor) for 100 linear foot$1,812.872 more rows
How much does it cost to remove a load bearing wall and install a beam?
How long can a beam span without support?
A 2×8 up to 12 feet; 2×10 to 15 feet and 2×12 to 18 feet. The larger the deck, the larger the joists.
What is the difference between an H beam and an I beam?
I Beams – unsurprisingly, I beams are shaped like the letter 'I'. However, contrary to steel H beams, I beams consist of two horizontal plates (otherwise known as flanges), connected by a vertical component (the web). I beams also have tapered edges and a slightly higher cross-section, compared to the flange width.
How big of a beam do I need to span 20 feet?
How far can you span a triple 2×12 beam?
Joist SpansSouthern Pine3-2X1012′-9″3-2X1215′-0″Douglas Fir-Larch, Hem-Fir, Spruce-Pine-Fir, Redwood, Cedars, Ponderosa Pine, Red Pine3X6 OR 2-2X65′-2″3X8 OR 2-2X86′-7″17 more rows
Do ceiling beams make a room look smaller?
The Long and Short of It. Beams running the length of the room make a short room seem longer. In a small house, or just as an afterthought of a bedroom or guest room, install beams parallel to the longest walls to emphasize the stretch of space.

Trinidad's Pitch Lake
Updated: Sep 1, 2020
By: Attorney Melissa D. Goolsarran Ramnauth
Photo source:
Trinidad's Pitch Lake is a world wonder. It is the largest and richest source of natural asphalt. The lake contains approximately 10 million tons of asphalt, spans 100 acres, and is approximately 250 feet deep. For reference, that is about 2 times bigger than Grand Central Station and deeper than the height of Cinderella's castle at Disney World.
Legend says that a local tribe was celebrating a victory against a rival tribe. However, in the midst of their celebrations, they began to cook and eat the sacred hummingbird. God allegedly punished the group by opening the Earth and creating the Pitch Lake to swallow their souls. God left the Pitch Lake as a reminder to others of the tribe's terrible sin. Local villages believe this legend because Amerindian artifacts and bones were found preserved (due to the asphalt) near the lake. The Amerindian word for asphalt was "piche."
The Europeans first learned of the Pitch Lake when Sir Walter Raleigh visited the island in 1595, around the time he was looking for El Dorado. The natives took Raleigh to the lake and he used the asphalt to caulk his ship. The asphalt was "most excellent," in his opinion, because it did not melt in the sun like the Norway asphalt.
In 1887, an American businessman secured a 42-year monopoly on the lake. As a result, many of the first asphalt roads in New York City, Washington D.C., and other eastern U.S. cities were paved using the asphalt from Trinidad's Pitch Lake. In conjunction, much of the Pitch Lake's profits went abroad to a foreign investor and not to the local Trinidadian population.
Scientifically speaking, Pitch Lake is located at the intersection of two faults. The oil at the intersection rises, the sun evaporates the lighter elements in the oil, and this process leaves behind the heavier elements creating the asphalt. Kerosene and oil also have been harvested from the Pitch Lake.
The Pitch Lake is not Trinidad's only treasure. Its people and their culture are equally as valuable to the rest of the world.

I'm interested in Sklyanin Algebras or Artin-Shelter regular algebras of type A. These are generated in degree 1 by three variables x,y,z, and have three defining relations in degree 2, which you can get by multiplying the matrix $$M=\begin{pmatrix} cx & bz & ay \\ az & cy & bx \\ by & ax & cz\end{pmatrix}$$ either on the left or right by the row/column vector of variables. (For every triple of numbers $a$, $b$, $c$, excluding a finite set, you get one of these algebras.)
Such algebras $A$ contain a central regular element of degree $3$, let me call it $g$. It has the property that $A/gA$ is the twisted homogeneous coordinate ring of the scheme of point modules of $A$, which is the cubic curve defined by $\det M$. $$g=c(c^3-b^3)y^3+b(c^3-a^3)yxz+a(b^3-c^3)xyz+c(a^3-c^3)x^3$$
This central element $g$ seems somewhat mysterious. In the original paper by Artin-Shelter it was apparently found by a computer search, in the foundational paper by Artin-Tate-Van den Bergh, only its existence (and its properties) are proved.
My question is: is there a conceptual way to get this element $g$? Sorry, it's a little vague. Thanks for any insight into this matter.
share|improve this question
If translation by the point $\tau$ of the elliptic curve $E$ has infinite order, then the center of $A$ is $k[g]$. That's the only intrinsic description of $g$ I know. There might be more known about the two central elements in the Sklyanin algebra of GKdim 4. Paul Smith has some notes that might be useful there: math.washington.edu/~smith/Research/Skly-survey.pdf – Graham Leuschke Apr 25 '13 at 20:22

On a quest to find the tastiest watermelon for your Fourth of July cookout? There's an Israeli app for that.
After experiencing the bitter frustration of trying to choose a good watermelon – only to get it home and find it hollow and tasteless – three computer science students at the Technion-Israel Institute of Technology decided to use technology to solve that age-old challenge. The result? A prototype that uses a smartphone, sensors and an algorithm to determine the quality of a watermelon in a matter of seconds – without ever opening the watermelon.
Through meetings with agricultural engineers and biologists around the world, Technion students Salah Abed Alehlim, Adam Garah and Ayman Sarha'an concluded there's a correlation between a watermelon's external and internal properties. It turns out that tone, color, stripe patterns, shape, and the size of the circle at the bottom of the watermelon all help determine what's inside.
The app takes a picture of the watermelon from three angles, and uses an algorithm to analyze its external properties. The app then gives each watermelon a taste rating between 1 ("atrocious") and 5 ("divine").
Does it work? According to the students, the app (which is not yet available to the public) scored 100 percent accuracy in experiments on 30 watermelons. They also say it can be applied to examine the quality of other types of fruit.


Category:Polar Bear Expedition
The Polar Bear Expedition (also known as the Northern Russian Expedition, the American North Russia Expeditionary Force - ANREF or the American Expeditionary Force North Russia - AEFNR) was a contingent of about 5,000 U.S. troops that landed in Arkhangelsk, Russia as part of the Allied intervention in the Russian Civil War and fought the Red Army in the surrounding region during the period of September 1918 through July 1919.


text: This paper considers semi-analytical solutions for a class of generalised logistic partial dierential equations with both point and distributed delays. Both one and two-dimensional geometries are considered. The Galerkin method is used to approximate the governing equations by a system of ordinary dierential delay equations. This method involves assuming a spatial structure for the solution and averaging to obtain the ordinary dierential delay equation models. Semi-analytical results for the stability of the system are derived with the critical parameter value, at which a Hopf bifurcation occurs, found. The results show that diusion acts to stabilise the system, compared to equivalent nondiusive systems and that large delays, which represent feedback from the distant past, act to destabilize the system. Comparisons between semi-analytical and numerical solutions show excellent agreement for steady state and transient solutions, and for the parameter values at which the Hopf bifurcations occur.

Comparison and Contrast
Which of these things is not like the other? Use the Compare-Object cmdlet to find out.
There may be times when need to compare objects to see what is different. This if often the case when you want to capture state information and see what has changed between "snapshots." For example, you might want to troubleshoot a problem by capturing process information in the middle of the night and compare it to a known good state. Let me show you how to use the Compare-Object cmdlet, which has an alias of Diff.
First capture the current running processes:
PS C:\> $before=get-process
Then start Notepad and Calculator. Now grab an after snapshot:
PS C:\> $after=get-process
The Compare-Object cmdlet compares a source object to a reference object. In our example we want to compare before and after:
PS C:\> diff $before $after
What you'll likely see is a long list with a side indicator that tells you which item doesn't belong in the other. Remember we're dealing with a collection of process objects and even though a process like PowerShell is still running, some properties like memory utilization will have changed between snapshots. That's normal. What we want is to narrow the comparison. We can do that by selecting a property:
PS C:\> diff $before $after -property Name
Now you should see that the Notepad and Calculator properties are only found in $after. Here's one more quick example. Get all the current running services:
PS C:\> $now=get-service
Stop or start some services and take another snapshot:
PS C>\> $later=get-service
You can use Compare-Object to return more than one property:
PS C:\> diff $now $later -property Status,Name
This will show the differences based on status as well as showing the service name.
Remember, you can use the Export cmdlets to save state information and then re-create the objects using the corresponding Import cmdlet. Save a current snapshot to a variable and compare the two.
Note that this is just an intro; be sure to look at the help file for Compare-Object to find out more.

Día de la Virgen de Guadalupe – Virgins, Kids and Indigenous Costumes
Every 12th of December in Guatemala on the Día de la Virgen de Guadalupe children throughout the country dress up in colorful, traditional indigenous costumes and carry an image of the Virgin of Guadalupe in local processions. Usually marimba and hordes of traditional food stalls go with the festivities.
Originating in Mexico after the Spanish conquest, when the Virgin Mary is said to have appeared to an indigenous peasant, the custom continues throughout the Americas.
In Antigua the celebrations take place in front of the beautiful baroque church of La Merced. Rustic mini-scenes backed by painted images of the Virgin are set up in front of the church and parents pose their children for photographers. Tiny replicas of adults, the boys have mustaches painted on their faces and the girls little baskets tied to their heads. Each scene has a variety of typical Guatemalan everyday items for the children to use as props including miniature marimba, tortillas on a comal, model horses and a strange collection of live chickens and toy tigers.
Colorful images of the Virgin.

Demand response (DR) has becomes one of the tools mostly used in adjusting users' electricity consumption pattern and behavior on the electricity market. In this paper, a single-objective optimization model with multiple constraints is established. Based on the electricity demand-price elasticity and the credit mechanism, further consider the impact of factors such as income, environmental awareness, family member and age, a more realistic subsidy mechanism is developed by taking into account the heterogeneity of users. The actual electricity load and price data are used for numerical simulation, and the results of economic index and load factor show that this model is more effective than the model which only considers the demand-price elasticity and the results show that the model is practical and effective.

Does Vinegar Kill Weeds to the Root?
Does Vinegar Kill Weeds to the Root?
Unfortunately, vinegar does not kill weeds to the root. While vinegar will degrade the biological material that weeds are made up of, this will typically only end up killing the leaves of older plants. That being said, there are some weeds that can be killed down to the root by vinegar.
In most cases, you'd be better off trying to kill younger weeds with vinegar, as seedlings tend to be less resilient than their fully-grown counterparts.
When you decide to start gardening, most people don't tell you about the many headaches that you can expect to experience while tending to your garden.
Pests are just the start of your issues, and it seems like once you finally manage to find a solution to them, you'll have to contend with an entirely different source of difficulties.
Weeds are the bane of any gardener or lawn-keeper. They make your garden or lawn look worse and they siphon crucial nutrients and water away from the plants that you actually want to see thriving.
Unfortunately, weeds are some hardy plants, and it can be tough to find a non-toxic way to deal with them.
In today's guide, we're going to take a look at one of these non-toxic methods, specifically, we're going to explore whether you can kill weeds to the root with vinegar.
We'll explore using different kinds of vinegar to kill weeds to the root and even take a look at some alternatives that you have available.
Does Vinegar Kill Weeds Permanently?
Theoretically, vinegar should be able to permanently kill weeds because it is a desiccant.
This means that it dries out the things that it touches, especially if it comes into contact with biological material like the cells that make up a plant.
The acetic acid in vinegar will gradually dry out each cell that it comes into contact with until the organism dies.
Most vinegars made for human consumption contain between 5% and 7% acetic acid, making them both safe to handle and environmentally friendly.
In theory, this means that you should be able to effectively kill any weeds in your yard or garden with a liberal application of your choice of vinegar.
Unfortunately, it doesn't ever quite work out this way because of how long vinegar lasts in soil. Since the acetic acid in vinegar will quickly wear away in soil, it won't be able to last long enough to do any lasting harm to the roots.
The very fact that acetic acid gets neutralized by soil is one of the main reasons why it's one of the most environmentally friendly weed killers.
The acid won't end up lingering long enough to do any lasting damage to any of the ecosystem, including other plants, pollinators like bees, and more.
To sum it up, the only kind of weed that you can expect tabletop vinegar to kill permanently is a seedling, as it won't have grown enough to be able to resist the vinegar enough to survive.

How Long Does it Take for Vinegar to Kill Weeds?
After preparing a spray bottle full of white vinegar to get some weeds out of your garden, you may be wondering exactly how much time you'll spend on the task.
The actual time you spend spraying the vinegar will be variable, as that will depend on the size of the yard that you're working on.
You'll start to see the leaves on the weeds drying out and dying away within the first few hours after you spray your solution on them. Hardier weeds may last a little longer before you start noticing the signs of them drying away.
In these cases, you may have to wait for up to 24 hours before you start seeing an effect.
Keep in mind that the yellowing and drying of the leaves doesn't necessarily mean that the weed is dead in the first place.
If you neglect to keep reapplying vinegar to the plant, then you'll notice that the plant will start getting healthier by the day until the leaves that were supposedly gone start growing back.
To keep the plant dead, come back to it every day and keep spraying it with vinegar on the days that you see the plant trying to sprout a new set of leaves.
Keep in mind that there's no guarantee that this method will kill the plant permanently, as you'll need to take out the roots to be truly effective.
What About 20% Vinegar?
So far, we've only discussed using tabletop vinegar to attack the root systems that are sustaining the weeds in your garden.
However, there is also horticultural vinegar, which is about four times more acidic than the kind of vinegar that we would normally consume. While using horticultural vinegar is safer than using commercial weed killers, it is still dangerous.
The vinegar that we put in our food is already highly acidic, but when the concentration of acetic acid in the vinegar reaches about 20%, it becomes nearly too dangerous to handle.
You certainly want to avoid using 20% vinegar if you don't have protective gear like goggles, gloves, and a long-sleeved shirt.
This is because 20% vinegar can cause chemical burns on contact with your skin. It being more powerful also makes it more effective at killing weeds down to the root.
Unfortunately, 20% vinegar won't work anywhere near as effectively as commercial weed killers because of how easily it disperses.
Even large amounts of 20% vinegar in your soil will likely not get to the root of the weeds that are plaguing you, so this is not as reliable of a method as you may expect it to be.
Also, be wary of getting 20% vinegar on any of your tools, as it can corrode metal, wood, and even concrete.
Does Apple Cider Vinegar Kill Weeds?
If 20% vinegar doesn't do the trick, maybe apple cider vinegar will. Apple cider vinegar has been touted in recent years for its healthy properties, but can it also be a versatile enough tool to see use in your garden?
Considering apple cider vinegar tends to contain between 5% and 6% acetic acid, it's a little on the weak side.
Compared to other kinds of vinegar that you may have available in the pantry, apple cider vinegar isn't much more or less effective because of its similar acetic acid levels.
Much like other kinds of vinegar, the most you can expect from apple cider vinegar is to kill the plant's leaves.
You can expect to wait for about a day for apple cider vinegar to kill the leaves on a plant, but you may see new leaves sprouting out within the next few days after that.
As with any other weed-killing method, you have to either kill or remove the root to make your efforts permanent.
Does Vinegar, Epsom Salt, and Dawn Dish Soap Really Kill Weeds?
Epsom salt is one of the most effective ways to kill any type of plant because of how it sucks the moisture out of the surrounding soil.
However, there's a reason that "salt the earth" has become a relatively common saying since it's very unlikely that anything will grow on salted soil for a long time to come.
Mixing salt into vinegar and dawn dish soap will make for an effective weed killer, but it will also kill anything else that you try to plant in that bit of land.
Salt is so insidious in soil because it doesn't take effect instantly, so you may not know the extent of the damage you caused until it's too late.
By the time ten days have gone by, the salt will have made its way into the earth, making it impossible for anything else to grow there, though it will also have killed any existing weeds.
Unlike vinegar, salt also won't be neutralized over time, making that plot of land a dead zone for years to come.
What Kills Grass and Weeds Permanently?
If you're looking to get rid of the weeds in your yard or garden permanently, then you may not be satisfied with the performance of vinegar, despite its safety and eco-friendliness.
Unfortunately, if vinegar was such a convenient way to kill weeds, everyone would be doing it by now.
Instead, due to the relative ineffectiveness of vinegar, gardeners tend to resort to chemical weed killers which can penetrate deep into the root system and destroy the weeds from within.
The downside to this approach is that you may end up damaging other plants in the area and even potentially rendering them toxic, based on the weed killer formula that you're using.
If you don't like the idea of potentially poisoning all of your other plants while trying to kill some weeds, then you can start killing weeds the old-fashioned way: by uprooting them.
While pulling weeds out by their roots may be a bit more challenging than just pouring something on them, it's a much safer alternative to using chemical weed killers.

10.12 Deleting the Junction
Deleting a junction removes the junction file and the trustees, trustee rights, and inherited rights filters that are explicitly set on the junction. It does not delete the data or trustee settings in the target location.
Changing the access path to the data might result in different effective rights for users at the target location. To avoid security or visibility issues, make sure to verify trustee settings in the target location before or after the delete. Before you delete the junction, you can use the Target Rights page for the junction to modify the settings. After you delete the junction, use any other method you normally use to view and modify rights.
 1. (Optional, recommended) Verify that the trustees and trustee rights settings at the target location are what you intend them to be when users access the data via a different path than the current junction.
 For information, see Section 10.8, Adding or Deleting Trustees for the Junction Target and Section 10.10, Modifying Trustee Rights for the Junction Target.

Water bridge (5mm length, 1mm diameter) between two glasses filled with heavy water, under a voltage of 15 kV.
In 1893 Sir William Armstrong reported a remarkable experiment: if a high voltage is established between two wine-glasses filled to the brim with pure water and connected by a cotton thread, a rope of water is formed and remains suspended between the lips of the two glasses. This "water bridge" can subsist for a few seconds even once the thread has been removed.
Recently, a group of physicists from Graz University, Austria succeeded on establishing a bridge (without any thread!) between the two glasses under a voltage of 20 kV. The length of the bridge may reach values larger than 1 cm, its diameter is of the order of a few mm and the lifetime currently exceeds 1 hour. Under the effect of the electrical field, the local temperature increases and reaches 60° C, a temperature sufficient to break the bridge. More...

I have one longer string, longString, and a set $S$ of shorter strings {ss1,ss2,ss3,...}. I'd like to print out longString but where the positions of the shorter strings are indicated in some nice way. For example, perhaps we could color the characters in the longer string with a specific specified color for each shorter string. I.e. where would would have an array like {{ss1,'Red'},{ss2,'Green'},{ss3,'Blue'},...} and would then color words appearing in longString Red if the word is ss1, Blue if the word is ss2, and so forth. The idea would be to shade Brown / etc. overlap regions if they occur.
Is this possible?
One can use StringPosition to return the first and last character position for a set of substrings or words appearing in a larger string, for example:
StringPosition["TheBrownFox", {"Brown","Fox"}]
out: {{4, 8}, {9, 11}}
Now, one of the more interesting parts of this question, IMO, is how we handle overlaps between substrings / words (i.e. ss1, ss2, ss3, etc.). For example, if we add the nonsense word "wnFo" to the previous example, we have overlapping words:
testString = TheBrownFox;
StringPosition[testString, {"Brown","Fox","wnFo"}]
out: {{4, 8}, {7, 10}, {9, 11}}
So we need to do a kind of "surgery" on the output list for StringPosition s.t. there is never a situation where we have {..., {integerOne, intTwo}, {intThree, intFour},...} where it is NOT the case that intOne < intTwo < intThree < intFour.
Update: Please see Kuba's very slick answer to my question concerning how one might do this: Identifying and isolating sections of overlap in a set of integer intervals
I am inspired by this example _URL_ where words of a certain length are highlighted and bolded.

 - $\begingroup$ _USER_ I really like your mark function - is there a good way to kind of map it over a large number of instances in the format given by StringPosition?

 $\begingroup$ As I think the handling of overlaps is the demanding part of your question I'd suggest to make an example with overlaps to provide a good test case for that... $\endgroup$ – Albert Retey Apr 1 '14 at 8:45
Using the code for mark, from linked question:
f[string_, cases_] := Module[{pos, agg, res},
 pos = StringPosition[string, cases];
 agg = {Switch[#[[ 1, 2]], 1, Blue, 2, Brown, _, Red],
 #[[ ;;, {1}]]
 } & /@ GatherBy[Tally@Flatten[Range @@@ pos], Last];
 mark[string, agg]
f["TheBrownFox", {"TheBrown", "BrownFox"}]
f["TheBrownFox", {"The", "Fox"}]
f["TheBrownFox", {"The", "eBrownF", "eBrownFox"}]
enter image description here
Detecting overlaps is based on my code from Identifying sections of overlaps in a set of integer intervals
 - $\begingroup$ Shouldn't this already handle any situation where there is an overlap between two or more of the substrings? $\endgroup$ – Bob2Alice Apr 1 '14 at 10:07
 - $\begingroup$ I see, so you were talking about assigning a different color if we have somwething like: f["TheBrownFox", {"The", "eBrownF", "eBrownFox"}] $\endgroup$ – Bob2Alice Apr 1 '14 at 10:11
 - $\begingroup$ That's really great. I also noticed that you can take the coloration specification, like Blue and write {Large,Blue} or {Bold, Blue}, which is quite nice. $\endgroup$ – Bob2Alice Apr 1 '14 at 10:17

 - $\begingroup$ Ok, I'm reluctantly unaccept, lol. If you wouldn't mind, could you add a brief descriptor for your algorithm for detecting the overlap? I'd just like to make sure I understand. $\endgroup$ – Bob2Alice Apr 1 '14 at 10:21
Here is another way to achieve what you want. It is neither very elegant nor very efficient, but should do what I think you try to achieve:
highlight[text_String, rules_List] :=
 Module[{positions, overlap = Underlined},
 positions = SortBy[
 Flatten[Thread[StringPosition[text, #1] -> #2] & @@@ rules, 1],
 positions = positions //. {
 {h___, {s1_, e1_} -> c1_, {s2_, e2_} -> c2_, t___} /;
 s2 <= e1 :> {
 {s1, Min[e1, s2] - 1} -> c1,
 {Min[e1, s2], Max[e1, s2]} -> overlap,
 If[e2 >= Max[e1, s2]+1, {Max[e1, s2]+1, e2} -> c2,Unevaluated[Sequence[]]],
 ToString[Style[StringTake[text, #1], #2], StandardForm] & @@@ positions,
 positions[[All, 1]]
 "The brown, brown fox with overlapping matches...",
 {"brown" -> Brown, "fox" -> Red, "app" -> Gray, "lap" -> Orange, "erlapp" -> Green}
The "difficult" part with the overlapping strings I tried to solve with a potentially inefficient pattern matching construct in a ReplaceRepeated (//.). Overlaps are unerlined in the above code but you could of course change that. If efficiency does matter or my approach turns out too be to naive you could try to combine my function with a smarter way to handle these overlaps...

Ways Parents, Students Can Research Campus Safety
Prospective students should explore campus safety and crime statistics as they consider colleges….
Georgia (Jun 16, 2014)By
Link To Article
Prospective students should explore campus safety and crime statistics as they consider colleges.
Sexual assaults, school shootings and other forms of on-campus violence are a major part of the national discussion of campus safety. The threat of a stolen laptop isn't as frightening, but there are many types of crime that can affect college students.
As prospective college students and their families try to choose the right school, researching campus safety can seem daunting, uncomfortable or even impossible.
To thoroughly evaluate a school's safety, prospective students need to research crime statistics, ask current students and campus staff the right questions and explore the programs universities have to protect and assist students, experts say.
[Learn how to stay safe on a college campus.]
Under the law, schools must submit an annual security report, maintain a crime log, share statistics for a variety of crimes that happen on campus and in some off-campus facilities, issue timely campus alerts, maintain a fire log and create policies to handle reports of missing students.
Families should first check the annual security report, which schools must submit by Oct. 1 each year, says Abigail Boyer, assistant executive director of programs at the Clery Center for Security On Campus.
The Department of Education has a site that allows users to research statistics by institution. Families should also be able to find the information through a university's website.
The Clery Act provides basic rules, but colleges have flexibility in how they implement certain sections, including how they handle campus alerts about safety issues such as a shooter.
For example, the length of time it takes for a student to receive a notification from the campus in an emergency is important but varies by school, says Robert Lang, who heads up security efforts at Kennesaw State University. Lang says that families should also ask about the variety of alerts a school uses beyond text messages and emails. Kennesaw's alert system includes computer pop-ups that can override classroom lectures, messages that display on digital signs around campus and a siren system.
Lang encourages families to ask schools who handles campus safety measures and how those measures are divided up. Some schools may have departments and programs dedicated to campus security and safety or have university police, while others may work with local police.
Families should also think about where students will spend time when they're not on campus.
"You need to do some homework too, about not just the campus itself, but the city surrounding it," Lang says.Under a federal law known as the Jeanne Clery Act, brick-and-mortar schools that receive federal student aid are required to share information about crime on and around their campuses. …

A Myth Explaining Why Parrots Are Different Colours
A myth submitted to the site by Megan Coles
A long time ago in Greece every animal was colourful except for the parrot. The parrots were dull and boring. The parrots hated being like this because nobody liked them. The parrots were fed up with this and wished the other animals would be nice to them.
One day something amazing happened ………
It started to rain, the animal were fascinated by this as they had never seen a single drop of rain in their whole life. The sun was still shining and the air was still warm, the animals were very confused.
A couple of hours later an elephant saw the colours: Red, orange, yellow, green, blue, indigo and violet. He trumpeted and every one looked at him. The elephant pointed his truck at the pretty colours in the sky. All the other animals were shocked. What were all the pretty colours in the sky?
The animals went over to the parrots to ask what all the pretty colours were in the sky as they were most intelligent of them all.
It was a rainbow of course.
A couple of minutes later there was a popping sound and colours were flying off in every direction. One spark landed on a parrot and the parrot turned red blue and yellow.
This started to happen on all the parrots. The only thing that was different about all the parrots was that they were all different colours.
That is why parrots are beautiful and colourful today.

The Castello Plan is an early city map of Lower Manhattan from 1660, created by Jacques Cortelyou, surveyor of then named-New Amsterdam (later renamed by British colonial settlement as New York City).
Around 1667, cartographer Joan Blaeu bound the plan, together with other hand-crafted New Amsterdam depictions, to an atlas, which he sold to Cosimo III de' Medici, Grand Duke of Tuscany. This transaction most likely happened in Amsterdam, Netherlands, as it has yet to be proven that Blaeu had ever set foot in New Netherland.
It is covered extensively in volume 2 of I. N. Phelps Stokes' six-volume survey The Iconography of Manhattan Island.

C++ Question
C++ template function, same type, multiple instantiations: shares one same copy of code? EVEN in different cpp/object files
For example, consider the following code:
// f.h
template
int f(T x) {
return x+1;
If we instantiate it in both
//foo.cpp instantiation:
int i = f(1);
//bar.cpp instantiation:
int j = f(2);
Will the final program uses only one copy of code? Is that so, when
is hidden but only the object file
is provided?
I think, since each cpp files are compiled independently, both
must contains
. The linker should see same duplicate signature, and use only one copy. Am I right?
Yes, the linker will generally fold duplicate identical template instantiations away. Doing so is pretty much required to avoid an explosion in binary size when templates are involved, and to maintain some standard required invariants such as equivalence of function pointers. This behavior is sometimes called fold by name.
Beyond that, some linkers will even fold away all symbols that happen to be identical in content (i.e., compile the same code), even if they don't originate from the same definition. This is sometimes called fold by value, but unless done carefully may break the letter of the standard (i.e., because function pointers to different functions now compare equal).

Many scientists and civil engineers are mistaking alkali activation for geopolymers, fueling confusion, using them as synonyms without understanding what they really are.
To sum-up: Alkali-Activated Materials (AAM) are NOT Polymers, so they cannot be called Geo-Polymers. Geopolymers are NOT a subset of AAM because they are not a calcium hydrate alternative, the chemistry is radically different. Those who claim that both terms are synonyms are promoting a misleading scientific belief. Learn why by watching these three videos.
In his three recent keynotes at the Geopolymer Camp 2014, Geopolymer Camp 2015, and Geopolymer Camp 2016, Prof. J. Davidovits explained why Alkali-Activated-Materials are not Geopolymers, or why alkali-activation is not geopolymerization. We have selected all the sequences that had been dedicated to this issue in the GPCamp-2014, 2015 and 2016 keynotes. These new videos are titled: Why Alkali-Activated Materials are NOT Geopolymers. You will finally understand why they are two different systems.
Part 3 (new, 2016): AAM are not polymers, so they cannot be called "geopolymers"
Prof. Joseph Davidovits emphasizes the fact that Alkali Activated Materials (AAM) are not polymers, so they cannot be called "geopolymers". He presents what scientists are now writing about this issue. They now agree with proven facts that it is a big scientific mistake to use AAM and geopolymer as synonyms, and people shall stop doing so. Geopolymer cement is not a CSH derivative; therefore, scientists are now stating that applying the CSH terminology from Portland cement is not only inappropriate, but also calling them NASH and KASH is totally wrong. Those who purposefully use and propagate these misleading languages delude the understanding of the true chemical reactions that really occur (never a hydrate or a gel, but a polymer), resulting in confused interpretations.

Part 1 (2014): AAM are not geopolymers, two different chemistries
Prof. J. Davidovits explains the main differences between AAC (Alkali-Activated Cement or Concrete), AAS (Alkali-Activated Slag), AAF (Alkali-Activated Fly Ash) and Slag-based Geopolymer cement, in terms of chemistry, molecular structure, long-term durability. In a second part, on hand of the industrialization of Slag/fly ash-based geopolymer cement/concrete implemented by the company Wagners, Australia, he focuses on the results provided by the carbonation testing data obtained for ordinary Portland cement, AAS and EFC (Slag/fly ash-based geopolymer). The tests were carried out at the Royal Melbourne Institute of Technology RMIT in Australia. Geopolymer behaves like regular Portland cement, whereas AAS gets very bad carbonation results.

Prof. J. Davidovits makes a clarifying statement about all the false ideas and assertions written by several alkali activated materials scientists (incorrectly using the word "geopolymer" for marketing purpose in place of AAM) and blindly imitated by others. He explains why it is a true polymer with a well-known and understood chemistry (as opposed to those who claim it is a "gel" of unknown character), mentions the historicity and discovery of geopolymer chemistry, the real contributions of Glukhovsky and what he really wrote about geopolymers.

Fine soaps hand crafted in small batches
Soap on a Rope
Making soap on a rope is easy especially if you're making one out of soap scraps. That's right. We're using soap scraps to make soap on a rope either for your personal use or to give to someone else. Soap on a rope is something you can do to make use of those soap scraps instead of just throwing them away or letting it soak in your soap dish. Let's begin making your very first soap on a rope with the following steps.
First, you will need to prepare the materials needed for soap on a rope. These are the soap scraps, warm water, and nylons. You'll need 1 cup full of soap scraps to make soap on a rope. Now that you've gathered all the materials, let's start by breaking up the soap scraps into tiny little pieces. It will be best to use a grater or knife. That's how small it should get. Now, prepare a mixing bowl and place the grated soap scrapes in the bowl. Next, prepare a half cup of warm water. Pour it into the bowl and let it stand for about an hour.
After an hour, start kneading the soap and the water together as if you are kneading dough. Make sure to make it smooth and come up with the consistency of thick dough. If needed, add more warm water as needed. Make sure to add only a little at a time. You can use a tablespoon to make sure you only add little amount of water. If you want to add color, add a few drops of food coloring to the mixture until the desired color is achieved. Blend well. Now, it's time to shape the mixture into a ball. Lay a piece of wax paper on the table and set the soap on top. It will take at least 24 hours to dry.
Once dry, cut about 12 inches nylon and create a loop around the soap ball. Tie the ends of the nylon above the soap ball. Now, you can hang your soap on a rope in the shower!

Oldest Observatory in Americas Discovered in Peru
Richard A. Lovett
for National Geographic News
|May 16, 2006|
The oldest astronomical observatory in the Western Hemisphere has been discovered on a hillside a few miles north of Lima, Peru, archaeologists recently reported.
Researchers also found ornate carvings more sophisticated than any before seen in the region.
The site dates back 4,200 years800 years before such artistic and scientific skill was previously known to have existed in the Americas.
The find was part of an ancient temple built by an unnamed civilization from Peru's "pre-ceramic" period, which predated the better-known Inca culture by thousands of years.
Temple structures, including a giant carving of what looks like a frowning face, align with the directions of sunrise and sunset at critical points in the agricultural calendar, including December 21, the start of the Southern Hemisphere's growing season, and June 21, the end of harvest.
This proves that the ancient civilization was already highly dependent on agriculture, said Robert Benfer, anthropologist at the University of Missouri, Columbia, who was one of the lead researchers of the find.
"These people went to a lot of trouble to mark the agricultural calendar," Benfer said.
(See a National Geographic magazine feature on the Andes' pre-Inca empires.)
Benfer's team also found a sculpture of a life-size musician playing a shell trumpet.
"The torso is in the round," he said, referring to the fact that the sculpture is three-dimensional and can be viewed from different angles. "The legs are over the edge of a balcony in high relief."
It's a significant artistic find because of the round torso, Benfer explained. All other known Andean sculptures from that era were two-dimensional reliefs and not done in the round.
"We were in no way prepared for finding this kind of stuff," Benfer said. "It was absolutely unexpected."
Benfer's conservation work on the sculpture was funded by the National Geographic Society's Committee for Research and Exploration. (National Geographic News is part of the National Geographic Society.)
Benfer announced his discovery at an April meeting of the Society for American Archaeology in Puerto Rico.
The sculptures were beautifully preserved thanks to the temple-builders' habit of using temples for only a short time before carefully covering them up and building new ones on top.
Even so, Benfer said, archaeologists were lucky that the site hadn't been looted.
Treasure hunters had dug a 20-foot (6-meter) wide hole 7 feet (2 meters) deep into the layers above the site, he said.
The would-be looters stopped only inches from the temple.

Print Migrator
From Galen Healthcare Solutions - Allscripts TouchWorks EHR Wiki
Jump to navigation Jump to search
This page describes how to use the Microsoft Print Migrator to move printer definitions from one server to another. This is especially useful if you want to update the test server with the printers defined on the production print server or if you are creating a new Print Server and want to define all of the printers quickly. This utility will copy the definitions and drivers to the new server.
Download the utility
The first step is to download the utiliy. You can find this on the Microsoft website by searching for Print Migrator or using the following URL:
Print Migrator 3.1
Download the utility and save it to a directory that you'll remember. This toll needs to be on each server you need to backup or restore printer definitions to.
Backing up the Printer Definitions
 1. After downloading the application, find the printmig.exe file you saved and double-click it. This will open the application and show the following summary:
 1. Select the "Actions" drop down and choose "Backup".
 2. Select the path that you'd like the CAB file saved to and name it appropriately. I typically recommend a clear name with a date of the backup.
 3. Once you've selected the location, the program will take a few minutes to create the backup file. Once it has finished, it'll say "Backup Completed". You are done with the backup.
 1. Copy the CAB file you created to the server that you'd like to restore the definitions to.
Restoring the Printer Definitions
 1. Connect to the Server that you'd like to restore the printer definitions to.
 2. Ensure that the CAB file created previously and the PrintMig.exe file exists on this server.
 3. Double-click the PrintMig.exe file.
 1. Select the "Actions" drop down and choose "Restore".
 2. This will ask you to select the CAB file you'd like to restore. Find the CAB file created previously and select "Open"
 3. The process will begin restoring the drivers and printer definitions.
 4. If you recieve the following error, you must Disable Kernal Mode Driver Blocking.
 1. If you receive this error, press OK to terminate the restore.
 2. Once the Restore process teminates completely, review the following article to adjust the setting:
Installing Kernel Mode Printer Drivers
 1. Once the setting is correct, rerun the restore following the steps above.
 2. When the process completes the application will say "Restore Complete".
 3. At this point, all of the printers should appear in the Windows Printer and Faxes page. They will need to be enabled in TouchWorks if they need to be used there, but it should reflect the full list of printers on the production server.

Because the friar prepares a potion contrary to anything known to science, some critics have labeled this a supernatural element in the plot. Is it plausible that the friar should have in his possession a potion capable of making a person appear dead for a set length of time?

Answered by Aslan
Plant science and apothecary science were well established in Elizabethan times. They certainly had sedatives made from plant extract so we can accept the Friar's potion, even if the idea of a prolonged "sleep" is a little far fetched.

On February 28, 2003 the Government of Nova Scotia proclaimed the Fire Safety Act Bill 101 and the Fire Safety Regulations. The Act requires all municipalities in the province appoint a Fire Inspector to provide a basic fire safety inspection service commencing September 1, 2003. The intention of the legislation is to make Nova Scotia a fire safe province through a cooperative effort between the province and the municipalities.
Role of Fire Inspector
The duty of a municipality under the Act is to establish a system of fire-safety inspections of land and premises as required by the Regulations to provide for compliance with the Fire Safety Act, Fire Safety Act Regulations, and the Fire Code.
Municipal Fire Inspectors work in concert with the Office of the Fire Marshal and Deputy Fire Marshal in establishing a basic fire inspection service within the municipal jurisdiction.


Farther vs Further
These two English words are very similar; keep reading for further information.
Farther means "more far/distant" in physical space.
Tom ran farther than Bill.
Which is farther, New York or Los Angeles?
Farthest means "the most far/distant."
I prefer the seat farthest from the window.
Pluto was once considered the farthest planet from the sun.
Further means "more far/distant" figuratively or non-physically, and can also mean "more/additional":
Nothing could be further from the truth.
Who is further along in her research?
Do you have any further ideas?
Further is also a verb: "to advance":
This class will further your understanding of ethics.
Furthest means "the most far/distant" figuratively.
That is the furthest thing from my mind.
The Bottom Line
Many English speakers use both farther and further to mean "more far" in space, but only further can be used for non-physical distance and to mean simply "more." If you are talking about actual distance, you can usually use either word without raising any eyebrows, but keep further in mind for all of your English furthering efforts.

Take the 2-minute tour ×
I came across the following exercise in Spivak's book: Suppose that you have a function $f$ such that $f'(x) \ge M > 0$, for any $x \in [0,1]$. I would like to show that there is an interval of length $1/4$ contained in $[0,1]$, on which $|f(x)| \ge M/4$.
My feeling is that this can be shown using the Mean Value Theorem: Applying this yields, for any $x \in (0,1]$, that $$ \frac{f(x) - f(0)}{x-0} \ge M. $$ However, I don't see how to proceed from here, as I don't have a lower bound for $f(0)$.

1 Answer 1
up vote 1 down vote accepted
Here's a proof that doesn't use the MVT. (Well, perhaps indirectly.) Suppose to the contrary no interval of length 1/4 satisfies the property. Hence, there must be a $t_0 \in [0,\frac{1}{4}]$ so that $|f(t_0)| < \frac{M}{4}$. We then have $\frac{-M}{4} \leq f(t_0)$, from which we obtain the inequality $$f(t + t_0) \geq Mt + f(t_0) \geq M\bigg(t - \frac{1}{4}\bigg).$$ We now see that if $t \geq \frac{1}{2}$, then $f(t + t_0) \geq \frac{M}{4}$. But $t_0 + \frac{1}{2} \leq \frac{3}{4}$, and so $f(x) \geq \frac{M}{4}$ on the interval $[t_0 + \frac{1}{2},1] \supset [\frac{3}{4},1]$.

Is it time to stop obsessing over MadELeINE?
Why the Madeleine McCann case epitomises a narrative of white privilege
By El Barnes
The Madeleine McCann case is the most notorious missing person's case in history.
Almost twelve years later, Operation Grange has received a total of £11.75m of government funding, the most recent instalment having been granted in October 2018. But with 1 in 200 children going missing each year in the UK alone, is it time to finally stop obsessing over Madeleine McCann?
Before continuing, it must be addressed that this is a devastating case which has at the heart of it a beautiful and innocent little girl who, no matter which theory you choose to believe, has been met with an exceedingly tragic fate. I do find it interesting, though, that the only other case involving a child that has had an international audience just as captivated is the 1996 murder of JonBenét Ramsey in Boulder, Colorado. The most significant point of contrast between the two is that JonBenét's ordeal culminated with the discovery of a body, but the similarities don't start and end with public reception.
Like Madeleine, JonBenét was thought of as something of a juxtaposition between prized possession and least favourite child. Like Madeleine, JonBenét suffered the most horrific fate with her – apparently oblivious – family close by. JonBenét's brother, like Madeleine's siblings, was completely unaware and came out unscathed. As with Madeleine's case, evidence arose after the fact that pointed towards some kind of familial involvement. Like Madeleine, JonBenét was a white middle-class child, born to wealthy and respected parents. Like Madeleine, JonBenét was innocence personified – a young child with fair hair, fair skin and coloured eyes.
According to the charity Missing People, someone is reported missing every 90 seconds in the UK.
That means that since Madeleine's disappearance over 4.2m others have been reported missing, the majority of these being children, which begs the question: why Madeleine? It seems crass to suggest that an innocent and ill-fated child should become an unfortunate symbol of white privilege, but the sad truth is that when a person of colour and/or an immigrant or refugee goes missing, the media is far less likely to pay attention. A scroll through the current list of missing persons in the UK will reveal a glaring and cruel reality: people of colour make up a significant majority of missing persons, despite the population of the UK being 86% white.
What really saddens me about this is that I couldn't name a single person of colour on this page; the only missing persons' cases I've seen media coverage of recently are that of 16-year-old Liam Smith from Aberdeen, 21-year-old Libby Squire from Hull and 19-year-old Daniel Williams from Reading. The common denominator? The victims whose faces the media has chosen to circulate are all white.
I'm not suggesting that these three people received the media attention they deserved, or anywhere near as much as Madeleine.
I'm not even suggesting that Madeleine has received more than she deserves; I firmly believe that everything should be done to uncover the circumstances of her disappearance and bring the perpetrator(s) to justice. She, as a child, and an innocent victim, deserves that much. But if the government is incapable of providing such extensive and sustained funding, and the media incapable of giving such extensive and sustained air-time, to every child that goes missing, then it shouldn't be provided to one in particular. After all, it's not just Madeleine whose image conjures up reminders of the perpetuation of white privilege – it's her parents, too.
All too often Madeleine herself becomes lost in the earth-shattering reverberations of the tempestuous see-saw that is the public opinion of Kate and Gerry McCann and no matter which side of the see-saw you are on, you are sure to have an opinion. You are sure to believe that they are victims of unimaginable tragedy or evil perpetrators of a heinous crime. You are sure to know their faces. You most likely know that in just the first 10 months following Madeleine's disappearance, the public donated £2m to the McCanns. Picture Madeleine, and you inevitably picture Kate and Gerry along with her; their names and faces and numerous details of their lives…and yet so many names of actual missing people in the UK draw a blank.
But instead of contributing to an endless media circus and becoming another extension of the problem, let's talk about the missing people of colour in the UK and remind them, wherever they are, and their families, that we haven't forgotten them.
Recent photos can be found at, where you can also report sightings.
Let's find 16-year-old Ismael Berkoun, missing from Westminster since March 13th.
15-year-old Iesha Manuk Welsh, missing from Lambeth since March 13th.
14-year-old Rhys Moore-Campbell, missing from Camden since March 7th.
15-year-old Tamara Oram, missing from Walthamstow since March 4th.
17-year-old Tung Nguyen, missing from Luton since February 18th.
16-year-old Haftom Manush, missing from Birmingham since February 10th.
16-year-old Amy Mendes, missing from Croydon since January 22nd.
Let's circulate their names and faces and keep them in our thoughts as much as we have kept Madeleine there for the past twelve years and let's hope, just as fervently, that they too will be found.
