$$ \nabla \times \mathbf{E} = 0$$
The curl of $\mathbf{E}$ is 0 because it is a conservative field. A conservative field can be described by a potential such that
$\mathbf{E} = \nabla \phi$. The curl of the gradient of a scalar field ($\nabla \times \nabla \phi$) is 0; Hence, the curl of $\mathbf{E}$ is 0.
The electrostatic equation demonstrated in this visualisation is:
$$\oint \mathbf {E} \cdot \mathrm {d} {\boldsymbol {l}} = 0$$
As you can see from the visualisation on the right the net flux through a loop in an electric field is always zero,
regardless of the positions of charges or even if there is some background field: as long as the background
field has no curl!
Another way of thinking about this equation is by using Stokes' Law which states:
From this it is clear that the first equation, and the fact that electric fields have no curl are identical.
This also implies that electric fields are conservative, since the loop integral is always zero, and the field
has no curl.
Insert interactive part for the first visualisation here.
Loop type:
Background Field:
$\displaystyle\oint\mathbf{E.dl}=$

We are using a Riemann sum to integrate, so the number of steps is referring to the number of steps used in the numerical integration.


Why the cloud?
Cloud providers such as google, amazon, and microsoft azure have been reinventing the notion of infrastructure and hosting.
Businesses no longer want to buy, house, maintain, and administer servers. Don't get bogged down in hardware and wires, we are experienced with all 3 major cloud providers (along with more traditional hosting options like DigitalOcean and Dreamhost). The cloud will guarentee your software and your technology needs are available when and where you need them.
The cloud means faster results and less people

Topics
Actions Defined by AWS IoT SiteWise
You can specify the following actions in the Action
element of an IAM policy statement. Use policies to grant permissions to perform
an operation in AWS. When you use an action in a policy, you usually allow or
deny access to the API operation or CLI command with the same name. However,
in some cases, a single action controls access to more than one operation. Alternatively,
some operations require several different actions.
The Resource column indicates whether each action supports resource-level permissions. If
there is no value for this column, you must specify all resources ("*") in the
Resource
element of your policy statement. If the column includes a resource type, then
you can specify an ARN of that type in a statement with that action. Required
resources are indicated in the table with an asterisk (*). If you specify a resource-level
permission ARN in a statement using this action, then it must be of this type.
Some actions support multiple resource types. If the resource type is optional (not
indicated as required), then you can choose to use one but not the other.
For details about the columns in the following table, see The Actions Table.

Alphabet pasta, also referred to as Alfabeto, is pasta that has been mechanically cut or pressed into the letters of an alphabet. It is often served in an alphabet soup, sold in a can of condensed broth. Another variation, Alphaghetti, consists of letter-shaped pasta in a marinara or spaghetti sauce.
It is not clear who invented the alphabet soup but Knorr sold it in Europe already in the 1910s. One common American brand of condensed-style alphabet soup is Campbell's. This soup, like its competitors', is marketed towards parents for its educational value.<ref>{{cite book |last=Wolf |first1=Jackie |url=https://books.google.com/books?id=Laf_AAAACAAJ&dq |title=Campbell's Alphabet Soup Book |edition=illustrated |publisher=Picture Me Press |year=2002 |isbn=978-1571516398 |accessdate=2015-03-25 }}</ref>
A similar product, Alphabetti Spaghetti, was sold by the H. J. Heinz Company for 60 years before being discontinued in 1990. Like Campbell's alphabet soup, it contains alphabet pasta canned in tomato sauce, but no cheese. It was later reintroduced by Heinz in 2005.<ref>{{cite |title=Alphabet spaghetti back for a spell |date=7 April 2005 |newspaper=Daily Mail |publisher=Associated Newspapers |url=http://www.dailymail.co.uk./health/article-344045/Alphabet-spaghetti-spell.html |accessdate=2009-04-26 }}</ref><ref>{{cite |title=Dish that's write on |newspaper=Daily Record |date=7 April 2005 }}</ref>

Jason Derulo Denies Photoshopping His ‘Anaconda’ After Viral Pic Sets Internet Ablaze
The star of the upcoming “Cats” musical, Jason Derulo, caused massive outcry among his Instagram followers this week with a visibly… well-endowed picture of him from Bali.
American singer and dancer Jason Derulo has denied doctoring his viral photo that showed his massive physical endowment, blaming it on his “Haitian heritage”, TMZ revealed. The photo was posted by the singer this week and received a flurry of reactions, especially after Derulo laconically replied to a fan’s question about “what animal” he was “hiding in his pants”, simply writing “Anaconda”.
Unsurprisingly, the photo caused a massive outcry among the singer’s Instagram followers, with some suggesting that he should be renamed “Jason DeRULER” instead, commenting that something was “fighting to get out” from his underwear. Not all users believed that the photo was genuine, though.
Speaking to TMZ, Derulo rejected suggestions that he had doctored the picture, which attracted more than 4,000 likes, saying that he was “honestly” not expecting such attention.
“Photoshop? Photoshop? Don’t make me [pull it out]. There are not enough women in this area. Just know that us Haitians, we look different", Derulo said to the outlet when approached for a comment on Friday.
“It was in Bali. I honestly [didn’t] feel like that was going to be my most liked picture when I woke up this morning”, the "Cats" movie star revealed. “I posted the motherf***er very early. It was [a photo] from months ago. It was not even something that I just did”.
The 30-year-old singer insisted that it was his “Haitian heritage” that should be thanked for his physical endowment.
Jason Derulo, whose real surname is Desrouleaux, rose to international fame after the start of his solo career in 2009, achieving eleven Platinum singles so far. He recently starred in the "Cats" film based on Andrew Lloyd Webber’s legendary musical, which will be released this winter.


Global Consortium for Chemosensory Research (GCCR) is a diverse group of scientists, clinicians, patient advocates, and community partners that formed during the COVID-19 pandemic in March 2020. Members are distributed across 30 countries on five continents.
How prevalent is smell loss during COVID-19? Is COVID-19 related smell loss greater than smell loss due to other viral or respiratory illnesses? We predict that self-reported smell ability for respondents with COVID-19 will be lower than that of respondents without illness or those with other viral or respiratory illnesses.
This questionnaire includes items on smell, taste and chemesthesis function, as well as the collection of information on COVID-19 diagnosis. We also ask about COVID-19 symptoms, other viral and respiratory illness symptoms, other medical conditions, smoking, and medicine use. This will allow us to draw conclusions about how important the reports of loss of smell are relative to other symptoms of COVID-19 and if reports of loss of smell can aid in distinguishing between COVID-19 and other illnesses. Collecting data globally has the advantage of a large sample size and a reduced influence of local factors.

Details of the questionnaire can be found on our OSF page (link to be added soon!). Here we describe our planned data processing, statistical tests for hypothesis testing and exploratory analyses. You may also find the preregistration of this study there. You can download simulated data there. Data analysis scripts are available and anonymised data will also be made public there.
You can take the questionnaire here:
English Deutsch Español Français ItalianoThe gold standard for taste and smell loss testing is done in clinics with extensive test batteries. Self-reporting taste and smell ability shows only moderate agreement with those objective tests. Under the current challenge of social distancing we are developing an at home taste and smell assessment protocol to have more sensitive data on changes in taste and smell ability over time, in particular during COVID-19.
More details on home-test to be announced soon

public abstract class MetaTagHandler extends TagHandler
Every kind of markup element in Facelets VDL that has attributes that need to take action on a Jakarta Faces Java API artifact is associated with an instance of this class. This class is an abstraction to enable a rule based method for directing how different kinds of elements take different kinds of actions in the Jakarta Faces Java API. For example, consider this markup:
<h:inputText value="#{user.userid}"
valueChangeListener="#{user.newUserId}" />
This markup element corresponds to an instance of HtmlInputText
in the view.
HtmlImputText
has a number of attributes that are to be exposed to the page author.
HtmlInputText
also implements EditableValueHolder
, which extends
ValueHolder
. Each of these interfaces also expose a number of attributes to the page
author.
Facelets employes the strategy pattern to allow the manner in which all possible attributes are handled based on the nature of the Jakarta Faces Java API artifact associated with the markup element.
Subclasses override the createMetaRuleset(java.lang.Class)
method to return a MetaRuleset
instance encapsulating all
the strategies for all the attributes that make sense for this particular markup element. The runtime calls the
setAttributes(FaceletContext, Object)
method to cause those rules to be executed and applied.

The Java Flight Recorder (JFR) is a commercial feature. You can use it for free on developer desktops/laptops, and for evaluation purposes in test, development, and production environments. However, to enable JFR on a production server, you need a commercial license. Using JMC UI for other purposes on the JDK does not require a commercial license.
For more details about JFR commercial features and availability, see the product documentation.
For more details about JFR commercial license, see the license agreement.
The Java Flight Recorder records detailed information about the java runtime and the Java application running in the java runtime. The recording process is done with little overhead. The data is recorded as time stamped data points called events. Typical events can be threads waiting for locks, garbage collections, periodic CPU usage data, etc.
When creating a flight recording, you select which events should be saved. This is called a recording template. Some templates only save very basic events and have virtually no impact on performance. Other templates may come with slight performance overhead, and may also trigger GCs in order to gather additional information. In general, it is rare to see more than a few percentage of overhead.
Flight Recordings can be used to debug a wide range of issues from performance problems to memory leaks or heavy lock contention.
The following topic describes types of recording to produce a Java flight recording.
The following are two types of flight recordings - continuous recordings and profiling recordings.
Continuous Recordings: A continuous recording is a recording that is always on and saves, for example, the last six hours of data. If your application runs into any issues, you can dump the data from, for example, the last hour and see what happened at the time of the problem.
The default setting for a continuous recordings is to use a recording profile with extremely low overhead. This profile will not get heap statistics or allocation profiling, but will still gather a lot of useful data.
A continuous recording is great to always have running, and is very helpful when debugging issues that happen very rarely. The recording can be dumped manually using either jcmd or JMC. You can also set a trigger in JMC to dump the flight recording when some specific criteria is fulfilled.
Profiling Recordings: A profiling recording is a recording that is turned on, runs for a set amount of time, and then stops. Usually, a profiling recording has more events enabled and may have a slightly bigger performance impact. The events that are turned on can be modified depending on your use of profiling recording.
Typical use cases for profiling recordings are as follows:
Profile what methods are run the most and where most objects are created.
Look for classes that use more and more heap indicating a memory leak.
Look for bottle necks due to synchronization and many more such use cases.
A profiling recording will give a lot of information; even though, you are not troubleshooting a specific issue. A profiling recording will give you a very good view of the application and can help you find any bottlenecks or areas in need of improvement.
|
Note: A typical overhead is only around 2%, so you can definitely run a profiling recording on your production environment (which is one of the main use cases for JFR), unless you are extremely sensitive for performance or latencies. |


If p is the perimeter of a right angle triangle with integral length sides, {a,b,c}, there are exactly three solutions for p = 120.
{20,48,52}, {24,45,51}, {30,40,50}
For which value of p ≤ 1000, is the number of solutions maximised?
Conditions: $ a+b+c=p $, $a^2+b^2=c^2 $. If we want any solution for a certain p, it means the line $ a+b+c=p $ and the circle $a^2+b^2=c^2 $ have intersection, which means $ c \lt p-c \lt \sqrt{2}c $, => $ \frac{p}{1+\sqrt{2}} \lt c \lt \frac{p}{2}$.
$ \begin{cases}
a+b+c=p \\

Also, it is safe to assume $ a \lt b \lt c $, and $ 0 \lt \frac{p(p-2c)}{2} (=ab) \lt \frac{\sqrt{2}-1}{\sqrt{2}+1} p^2 $, so $ a \lt \sqrt{\frac{\sqrt{2}-1}{\sqrt{2}+1}} p $

Entrepreneurship @ UBC is the first entrepreneurship program of its kind in British Columbia. It links students and world-leading research, with the entrepreneurship ecosystem surrounding Western Canada, and an investor and mentorship network that spans the entire world. They needed a web strategy that communicated e@UBC's core messages in a way that alluded to the program's progressive nature. I designed and developed a website that included the allure of a sales site, and the practicality of an educational site.

--- layout: post status: publish published: true title: The Real Tragedy of the Arizona Anti-Gay Bill author: Ryan Hayden wordpress_id: 1616 wordpress_url: http://www.pastorryanhayden.com/?p=1616 date: '2014-02-27 13:36:56 -0600' date_gmt: '2014-02-27 19:36:56 -0600' categories: - Current Events - Civil Discourse tags: - homosexuality - gay rights - legislation ---
Below is a letter to the editor I submitted to our local newspaper:
Listening to the media coverage of Arizona's "anti-gay" bill saga over the last week, you'd think that it was the most hateful and backwards document ever penned by a state legislature. Seriously. You'd think the entire thing was a deliberate attempt to roll back anti-discrimination laws to the Jim Crow era and that the bill itself was dripping with homophobic vitriol.
Did anybody read it?
I did. Nowhere in it's whopping one and a half pages was there a single line that could be interpreted by any objective person as homophobic. In fact, nowhere in it's pages was there even a veiled reference to homosexuality.
The bill did not, contrary to the media hype, allow for a business to discriminate on religious grounds. All it did was give business owners the right to make their case in court that a law unnecessarily encroaches on their sincerely held religious beliefs and practices. It said nothing to color the outcome of the court case, it only gave religious business owners the right to a court case in the first place. It did nothing more than mirror the language of an existing federal law championed a decade ago by such a conservative religious bigot as Ted Kennedy, and would have added Arizona to the 18 states that have already accepted that language in their state definition of religious liberty. (None of which are allowing Christian restaurant owners to refuse lunch to a gay man.)
Even if you hate the bill - even if you are so anti-religion that you believe people's right to exercise their faith stops one step past the church door - you should be alarmed that the state of journalism has disintegrated so much that things no longer have to be proven discriminatory to meet with journalistic outrage. No, anything that even seems to hinder the very new political correctness in our society will have to overcome a tidal wave of universal media disdain.
You might see Jan Brewer's veto last week as a moment of triumph for gay rights, it very well may have been, but it was definitely a moment when hype and spin triumphed over actual content. People's most deepest right was on the line, the right to follow their conscience, and the media ran with boilerplate propaganda at the expense of the truth. That should be scary to more than just religious people.

Reagent - ClojureScript and React made easy
Recently I’ve started reading into Clojure and came across something really interesting. Clojure is a JVM based functional programming language, based on Lisp. React is a recent web frontend framework from Facebook that has been everywhere lately. React a reactive Javascript framework, similar to AngularJS, but takes a different approach in component management to make it much faster and more scalable. Now this is where it gets interesting - Clojure can be compiled to Javascript via the ClojureScript plugin. Combine the two and you get Reagent, a framework that integrated them together nicely.

Generating Java Spring-MVC code from Swagger Spec
(Edit, July 2017: This Async Spring template in Swagger codegen is deprecated and no longer maintained. Please use the normal Spring template or use a custom template instead. You’ll probably want the newer streaming API oriented convention in Spring 5.x anyway. The plugin and configuration example should still work with other available templates. Keeping this post for reference purposes) REST services skeleton code generation is a quick way to get started in implementing the service from popular Swagger spec describing the interface. In this post we’ll look at generating Java Spring MVC code from Swagger spec. There are a few frameworks out there, but at the time I couldn’t find the one that I want - and so I’ve created a new template for my needs. Here is a quick walkthrough on setting up code-gen for Java Spring MVC project.

Magnet Pattern in Scala
Continuing from the previous post on Scala’s Cake Pattern, here is a quick explaination of the Magnet pattern. Magnet Pattern You are probably familiar with method overloading (ie. multiple method with the same name, but different parameter). This is very popular in Java, but is still not available in some modern languages like GoLang because designer to argue it clutters up the language.

OSSL_PROVIDER is a type that holds internal information about implementation providers (see provider(7) for information on what a provider is). A provider can be built in to the application or the OpenSSL libraries, or can be a loadable module. The functions described here handle both forms.
Some of these functions operate within a library context, please see OSSL_LIB_CTX(3) for further details.
OSSL_PROVIDER_set_default_search_path() specifies the default search path that is to be used for looking for providers in the specified libctx. If left unspecified, an environment variable and a fall back default value will be used instead.
OSSL_PROVIDER_get0_default_search_path() retrieves the default search path that is to be used for looking for providers in the specified libctx. If successful returns the path or empty string; the path is valid until the context is released or OSSL_PROVIDER_set_default_search_path() is called.
OSSL_PROVIDER_add_builtin() is used to add a built in provider to OSSL_PROVIDER store in the given library context, by associating a provider name with a provider initialization function. This name can then be used with OSSL_PROVIDER_load().
OSSL_PROVIDER_load() loads and initializes a provider. This may simply initialize a provider that was previously added with OSSL_PROVIDER_add_builtin() and run its given initialization function, or load a provider module with the given name and run its provider entry point, OSSL_provider_init
. The name can be a path to a provider module, in that case the provider name as returned by OSSL_PROVIDER_get0_name() will be the path. Interpretation of relative paths is platform dependent and they are relative to the configured "MODULESDIR" directory or the path set in the environment variable OPENSSL_MODULES if set.
OSSL_PROVIDER_try_load() functions like OSSL_PROVIDER_load(), except that it does not disable the fallback providers if the provider cannot be loaded and initialized or if retain_fallbacks is zero. If the provider loads successfully and retain_fallbacks is nonzero, the fallback providers are disabled.
OSSL_PROVIDER_unload() unloads the given provider. For a provider added with OSSL_PROVIDER_add_builtin(), this simply runs its teardown function.
OSSL_PROVIDER_available() checks if a named provider is available for use.
OSSL_PROVIDER_do_all() iterates over all loaded providers, calling cb for each one, with the current provider in provider and the cbdata that comes from the caller. If no other provider has been loaded before calling this function, the default provider is still available as fallback. See OSSL_PROVIDER-default(7) for more information on this fallback behaviour.
OSSL_PROVIDER_gettable_params() is used to get a provider parameter descriptor set as a constant OSSL_PARAM(3) array.
OSSL_PROVIDER_get_params() is used to get provider parameter values. The caller must prepare the OSSL_PARAM(3) array before calling this function, and the variables acting as buffers for this parameter array should be filled with data when it returns successfully.
OSSL_PROVIDER_self_test() is used to run a provider's self tests on demand. If the self tests fail then the provider will fail to provide any further services and algorithms. OSSL_SELF_TEST_set_callback(3) may be called beforehand in order to display diagnostics for the running self tests.
OSSL_PROVIDER_query_operation() calls the provider's query_operation function (see provider(7)), if the provider has one. It returns an array of OSSL_ALGORITHM for the given operation_id terminated by an all NULL OSSL_ALGORITHM entry. This is considered a low-level function that most applications should not need to call.
OSSL_PROVIDER_unquery_operation() calls the provider's unquery_operation function (see provider(7)), if the provider has one. This is considered a low-level function that most applications should not need to call.
OSSL_PROVIDER_get0_provider_ctx() returns the provider context for the given provider. The provider context is an opaque handle set by the provider itself and is passed back to the provider by libcrypto in various function calls.
OSSL_PROVIDER_get0_dispatch() returns the provider's dispatch table as it was returned in the out parameter from the provider's init function. See provider-base(7).
If it is permissible to cache references to this array then *no_store is set to 0 or 1 otherwise. If the array is not cacheable then it is assumed to have a short lifetime.
OSSL_PROVIDER_get0_name() returns the name of the given provider.
OSSL_PROVIDER_get_capabilities() provides information about the capabilities supported by the provider specified in prov with the capability name capability. For each capability of that name supported by the provider it will call the callback cb and supply a set of OSSL_PARAM(3)s describing the capability. It will also pass back the argument arg. For more details about capabilities and what they can be used for please see "CAPABILTIIES" in provider-base(7).
OSSL_PROVIDER_set_default_search_path(), OSSL_PROVIDER_add(), OSSL_PROVIDER_unload(), OSSL_PROVIDER_get_params() and OSSL_PROVIDER_get_capabilities() return 1 on success, or 0 on error.
OSSL_PROVIDER_get0_default_search_path() returns a pointer to a path on success, or NULL on error or if the path has not previously been set.
OSSL_PROVIDER_load() and OSSL_PROVIDER_try_load() return a pointer to a provider object on success, or NULL on error.
OSSL_PROVIDER_do_all() returns 1 if the callback cb returns 1 for every provider it is called with, or 0 if any provider callback invocation returns 0; callback processing stops at the first callback invocation on a provider that returns 0.
OSSL_PROVIDER_available() returns 1 if the named provider is available, otherwise 0.
OSSL_PROVIDER_gettable_params() returns a pointer to an array of constant OSSL_PARAM(3), or NULL if none is provided.
OSSL_PROVIDER_get_params() and returns 1 on success, or 0 on error.
OSSL_PROVIDER_query_operation() returns an array of OSSL_ALGORITHM or NULL on error.
OSSL_PROVIDER_self_test() returns 1 if the self tests pass, or 0 on error.
This demonstrates how to load the provider module "foo" and ask for its build information.
#include <openssl/params.h>
#include <openssl/provider.h>
#include <openssl/err.h>
OSSL_PROVIDER *prov = NULL;
const char *build = NULL;
OSSL_PARAM request[] = {
{ "buildinfo", OSSL_PARAM_UTF8_PTR, &build, 0, 0 },
{ NULL, 0, NULL, 0, 0 }
};
if ((prov = OSSL_PROVIDER_load(NULL, "foo")) != NULL
&& OSSL_PROVIDER_get_params(prov, request))
printf("Provider 'foo' buildinfo: %s\n", build);
else

The main components of the web are computers, web browsers, servers, internet, content, and HTTP. The web is the entire collection of interconnected computers and servers which communicate with each other via a protocol known as HTTP. When an individual user visits a web page, the user’s web browser makes a HTTP request, which is sent over the internet, to the server hosting the appropriate HTML document. The server then sends back the HTML document to the user’s computer, which is then interpreted and displayed by the user’s web browser.
Computers are able to perform tasks which are encoded via a computer language such as HTML. While able to perform complex tasks more effectively than humans, any little error in the code can have huge problems and prevent the code from performing the desired task. Computers read code literally with no room for interpretation or understanding.
This first lesson detailed some of the key points of HTML, otherwise known as HyperText Markup Language. HTML documents comprise the majority of the content on the internet. HTML documents contain text content, which is the content seen by users, and markup, which controls how the text content looks. Each HTML document is comprised of HTML elements. These elements come in different sorts and are determined via tags.
“B” tag - Makes the text content bold.
“M” tag - Makes the text content initialized.
“Break” tag - Makes an one line break, has no closing tag.
“Paragraph” tag - Creates an "invisible box" around the text content.
“Anchor” tag - Makes a link to another page.
“Img” tag - Tags an image.
"Div" tag" - Makes a box around content which allows for markup of the content.
"Span" tag - Allows for markup of a single line of element.
Inline/Block- Elements come in either sort. Block
elements make an "invisible box" around text content and can have a determinable height and length.
Void Tag - A tag with no closing tag.
There are three languages used for web page development, HTML, Java, and CSS. HTML gives structure and content to a page. CSS, otherwise known as Cascading Style Sheets, gives style to the page elements, such as font size, text color, background, position, border, and etc. Java gives the web page an interactive element. While not obvious at first, every web page on the internet is comprised of boxes. Boxes are defined with the "Div" tag. To add style to each box, give each element a class attribute.
To see the structure of a web page, in Google Chrome use "Developer tools." What is shown is the structure of the web page as interpreted by the web browser. Generally speaking, the structure shown is described as a tree structure. This is because HTML elements can have other elements nested inside them, and so on and so forth. When examining a web page's code, all the code within the page can be modeled in a Document Object Model (DOM), which is a tree-like structure of a page's code. A good summary about tree structures can be found here. More information about DOMs can be found here.
Since every web page is comprised of boxes, start by Boxify a web page design, going from big boxes to small boxes. Boxes can exist within other boxes. The same web page design can be boxifed in different ways.
It's a good habit to avoid repetition of code whenever possible. This makes your code easier to read and reduces the chances of errors. As an example, when using lots of repetition of styling code, it not only means a greater chance of error, but makes it more difficult to make markup changes to all desired elements. To make a simple markup change, instead of changing a small amount of code in the CSS file, you would have to change the CSS code in each one of the desired elements. This in turn leads to a greater chance of error if some of the elements are missed or incorrectly modified. Why make your coding experience harder?!?
Selector - Term used to select all elements of a particular sort in a HTML document.
Class Selectors - Term used to select only a certain elements of a particular sort in a HTML document.
There are several ways to add CSS styling code to a structured HTML document:
1) Write the CSS styling code in a "Style" tag nested in the “Head” tag of the HTML document. This is fine for very small projects.
2) Link the HTML document to a separate CSS file. Both files are placed in the same project folder. Helps keep organization for larger projects. A “Head” tag is placed at the top of the HTML document with a "Link" tag inside.
3) Adding CSS styling in line with the HTML code. Very bad idea, leads to lots of repetition of styling code, more chances for errors in code.

Power BackUPSolutions offers industry-leading power quality products designed to protect your clients' business, data, resources and profitability. Even more, we complement these exceptional products with an unparalleled level of customer service, knowledge and expertise, not to mention very attractive price points to increase your profit margins.
A high-quality power protection solution is among the most cost-effective measures to prevent downtime. With the ability to cause irreparable damage and irretrievable loss of revenue, an unexpected loss of power can be crippling to an organization. Power outages, surges and spikes are estimated to ring up more than $150 billion in annual damages to the U.S. economy. And according to Dunn & Bradstreet, 59 percent of Fortune 500 companies experience at least 1.6 hours of downtime per week.
While downtime costs vary by industry and by the scale of business operations, some of the negative consequences include lost transaction revenue, wages and inventory; remedial labor costs; marketing costs; bank fees; and legal penalties from not delivering on service level agreements. And don’t forget the damages resulting from missed business opportunities; decreases in stock value; loss of customer/partner goodwill; brand damage; driving business to competitors; and bad publicity/press.
