React Native Camera – Libraries Comparison
Dawid Przydróżny
Sep 14, 2021 • 8 min read
For a long time in the RN environment, not much has happened in the field of libraries to support the camera.
We all used React Native Camera (RNCamera) because it was the most polished and recommended by the React Native community, but it seems that it is standing still and does not plan any active development. Fortunately, a new library has emerged from around the corner that could patch the hole of useful camera libraries in the RN environment: RN Vision Camera.
What is React Native Camera?
React Native Camera (RN Camera) is probably the most well-known camera library in the RN environment. We shouldn't be surprised because the start date for this library was just after React Native's release. It grew up with RN and has fulfilled its role through the years. The library was promoted and recommended by React Native for a long time, so the community that uses it is substantial. It's still a good library for using the camera in your app, just install React Native Camera and enjoy the cross-platform camera module with photo and video recording functionality. At this point, you may start wondering why this article was written at all when this library is mature, useful, and has a great community. There are a few problems with RN Camera: it has stopped developing and improving, there is a problem with maintainers, and finally, with better and better cameras in our smartphones we need more functionality and a better API to get the most out of the camera on our device — in summary, the library has become a bit rusty.
React Native camera libraries comparison
At the moment there are only three sensible libraries for using the phone's camera in RN apps, these are:
- Large community, mature product.
- Easy setup with just one additional step (permissions).
- Can be used with Expo.
- Good documentation with recipes.
- Valuable props to set autofocus, flash, ratio, white balance, exposure, zoom, and video quality.
- It is possible to switch between front and back cameras.
- Additional features like face detection, barcode detection, and text recognition.
- Library is actively looking for maintainers, which means it could be unsupported soon.
- Can't switch between all of the available camera lenses.
- There is no built-in UI, so everything must be implemented e.g. snap button.
RN Vision Camera
- Library is rapidly gaining popularity.
- Nice lifecycle mechanism that will keep the camera session if the app is in the background or the user is navigating to a different screen.
- The strongest point of the library — it can detect all device camera lenses and you can switch between them in the way you want.
- Each lens returns all possible formats you can use and additional props like min zoom, max zoom, it has torch, has flash, supports focus, supports raw capture, etc.
- There are some available presets that can be used (you can get lost with formats, it is usually around 60 of them available for each lens).
- It can take snapshots.
- Available frame processors — for example, it's possible to detect objects with the camera.
- Good documentation.
- Some additional installation steps needed like raise min iOS version, raise target Android SDK version, etc.
- Quite a fresh tool in the market, it will probably need some time to mature and release a really stable version.
- There is no built-in UI.
RN Image Picker
- Mature, popular, and maintained with a strong community.
- Simple to install and use.
- Can be used to pick already taken photos from the device.
- Can take a photo or even record video.
- Has a bunch of helpful props like max width, max height, media type, video quality, and duration limit.
- Only semi-good documentation.
- Limited possibilities for taking photos and recording video (but of course it's not the main purpose of this library).
Which RN camera library should you use?
For a simple app that will only use the camera to take a photo for a user avatar or record a short movie using default settings, the react-native-camera will be more than enough.
If you are building an app where the camera plays a bigger role and you need to get the most out of it, then go with react-native-vision-camera.
To select already taken photos that are stored in the phone's gallery, use the react-native-image-picker.
A strong point for react-native-vision-camera is the fact that react-native-camera is looking for maintainers, this will possibly make RN Vision Camera the default choice when it comes to a camera library for RN.
RN Vision Camera - implementation example (tutorial)
Below is an example of using the RN Vision Camera with basic tools to take a picture.
import React, { useRef, useState } from'react';
import { StyleSheet, Alert } from'react-native';
import { Camera, useCameraDevices } from'react-native-vision-camera';
import BottomButtons from './components/BottomButtons/BottomButtons';
import ImagePreview from './components/ImagePreview/ImagePreview';
import TopButtons from './components/TopButtons/TopButtons';
function App() {
 const camera = useRef(null);
 const [previewImage, setPreviewImage] = useState(null);
 const [showPreview, setShowPreview] = useState(false);
 const [torchActive, setTorchActive] = useState(false);
 const [frontCamera, setFrontCamera] = useState(false);
 /* Here we use hook provided by library to take available devices (lenses) */
 const availableDevices = useCameraDevices();
 /* useCameraDevices hook returns an object with front/back properties,
 that you can use to switch between back and front camera */
 const currentDevice =
 frontCamera && availableDevices?.front? availableDevices.front : availableDevices?.back;
 const takePhoto = async () => {
 try {
 const result = await camera.current?.takePhoto();
 if (result?.path) setPreviewImage(result.path);
 } catch (e) {
 Alert.alert('Error: ${e}');
 const flipCamera = () => setFrontCamera((prevState) =>!prevState);
 const toggleTorch = () => setTorchActive((prevState) =>!prevState);
 /* There is an additional check to prevent errors.
 Camera component needs a valid device prop,
 we need to stop rendering if the device is falsy value. */
 if (!currentDevice) return null;
 if (previewImage && showPreview) {
 return setShowPreview(false)} />;
} return (
torch={torchActive? 'on' : 'off'}
showPreview={() => setShowPreview(true)}
); } export default App;
Is it hard to create a UI in RN Vision Camera?
As we can see, not that much effort is needed to create a well-known standard camera UI in your app. With a minimal amount of code we have added the following buttons on the screen:
- Capture (center)
- Preview latest photo (left)
- Switch to front camera and vice versa (right)
- Flash (top-right)
This is only a small piece of the functionality that RN Vision Camera offers. There are a lot more options that can be used like zooming, recording, switching to wide-angle and telephoto lens, selecting photo/video format, setting video frame rate, and more.
React Native Vision Camera – my opinion
RN Vision Camera is really impressive when it comes to the possibilities it offers.
I can recommend it if you are looking for a functional camera library to use in your application.
This will be my choice for the camera library in my next project.

Farm diversification into tourism - Implications for social identity?
MetadataVis full innførsel
OriginalversjonJournal of Rural Studies 2011, 27(1):35-44 10.1016/j.jrurstud.2010.09.002
This article deals with how diversification and transformation of farming into tourism may influence the social identity of farmers. Based on a study of 19 farms run by couples engaged with agritourism, it shows how the development of tourism on the farms can be understood in a perspective of repeasantization; and how the couples draw on their farm work, culture and place to situate themselves in a new working role. Through food, stories, activities and themselves as hosts they mediate a strong farm identity. The article also explores how identities change through identifying three processes by which the 'new' work of tourism may destabilize identities. One is a shift in the meaning of farmer identity. Another is the gradual change towards a new master identity, and thirdly it finds a multiplicity of identities practiced as serial identities that shift as they relate to various social memberships and settings.

Is there a way of finding the absolute position of an element, i.e. relative to the start of the window, using jQuery?

.offset() will return the offset position of an element as a simple object, eg:
var position = $(element).offset(); // position = { left: 42, top: 567 }
You can use this return value to position other elements at the same spot:
share|improve this answer
I always forget this one, and find your post again when I google :p – Aren Jun 30 '11 at 23:14
This does not always seem to return the absolute position due to differences in borders etc. – Tom Jul 5 '11 at 12:07
I'm using chrome and the offset() does not return the proper top coordinate. It returns about 300 pixels more than the top coordinate of the element in the document instead. Why?? – SoLoGHoST Apr 23 '12 at 5:49
chrome, FF and IE are giving different results :( – Rizwan Mumtaz Apr 10 '13 at 7:02
_USER_ this problem appears in the android webview as well :/ – A Person Apr 13 '13 at 13:38
Note that $(element).offset() tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed you can get unexpected results.
If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed element's offset() value will be greater than the expected value by the amount you have scrolled.
If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop() value from the fixed element's offset().top value. Example: $("_TAG_").offset().top - $(document).scrollTop()
If the position:fixed element's offset parent is the document, you want to read parseInt($.css('top')) instead.

I was looking exactly for this! For the noob like me: the value to be subtracted is $(document).scrollTop() – Dr. Gianluigi Zane Zanettini Aug 20 '14 at 14:56
Awesome! This should be the top answer! – Shivanshu Goyal Dec 20 '14 at 1:44

How to handle a hung flow
DavidBrickell 270001MT2R Visits (13274)
Sometimes when developing a flow we find that the flow becomes non-responsive. This can be caused by a few different reasons but one of the most common is that the flow is stuck in a logic loop.
This can be caused by poor code design or design of the flow itself. Even after identifying and fixing the logic within the flow, you are still stuck with the task of replacing the deployed flow within the Broker.
WebSphere Message Broker has built in recovery measures. This means, if the Broker detects that the EG has crashed or stopped unexpectedly, it will try to restart this process. To avoid the flow going back into its hung state, you should shut down the input source. For example, you can disable the input queue if using MQ as your input source. After this is done, you can kill the EG process. When the EG restarts you will see an error stating the message flow couldn't connect to the input source. From this point you can stop the message flow and then delete it.
This will allow you to redeploy the corrected flow to replace the old one.

PRE-TREATMENT FOR COATING
cleanLASER has the technology needed when preparing surfaces prior coatings that removes virtually any kind of contamination from metal surfaces, including oxides, grease, oil, chlorides and many other organic and inorganic residues.
Laser surface preparation prepares surfaces without the problems related to conventional methods. Traditional surface preparation, such as abrasive blasting, solvent or chemical cleaning can leave harmful contaminants and residues on the surface that reduce coating bond strength while creating secondary waste. A laser cleaned surface is truly CLEAN with no clean-up required and not secondary waste to dispose.
- Cleaning and pre-treatment using laser light is abrasive ana consumable media-free
- Ideal preparation of metal parts
- High cleaning rates
- Laser cleaning produces surfaces with excellent bond strength quality for coating durability and corrosion resistance.
- Laser technology is ideally suited for flat or curved surface and parts with certain limitation for highly complex 3D geometries as well as elastomeric materials and plastics

From the Roman name Mauritius
, a derivative of MAURUS
Maurice was a 3rd-century Roman soldier from Egypt. He and the other Christians in his legion were supposedly massacred on the orders of emperor Maximian for refusing to worship Roman gods. Thus, he is the patron saint of infantry soldiers.
This name was borne by a 6th-century Byzantine emperor. Another notable bearer was Maurice of Nassau (called Maurits in Dutch), a 17th-century prince of Orange who helped establish the Dutch Republic. The name has been used in England since the Norman conquest
, usually in the spelling Morris


Monitoring Kafka activity in Streams Messaging Manager
You can use Streams Messaging Manager (SMM) to monitor Kafka activity. To do this, you run two SSH sessions, one for producing data to a Kafka topic and the other to consume the data from the Kafka topic. Then you go to the SMM UI from the Management Console to track the producer and consumer activity.
Now that you know how to configure a Kafka client to connect to the Kafka cluster in CDP, generate some activity and monitor it using SMM. To do this, you collect machine usage data from the broker host using the vmstat command and stream that data into the machine-data topic.
For detailed and comprehensive information about SMM, see Streams Messaging Manager.
 1. Start by opening two SSH connections to the same broker host.
 2. On the first session, run the following command.
 BROKER_HOST=$(hostname -f)
 vmstat 1 1000 | kafka-console-producer \
 --broker-list $BROKER_HOST:9093 \
 --producer.config \
 --topic machine-data
 This command runs vmstat and sends each line from its output as one message every second to the machine-data topic.
 This example assumes that you are using LDAP authentication but you can use the authentication method of your preference.
 Leave the session running.
 3. On the second SSH session, run the following command to consume the data:
 BROKER_HOST=$(hostname -f)
 kafka-console-consumer \
 --bootstrap-server $BROKER_HOST:9093 \
 --consumer.config \
 --topic machine-data \
 --group machine-data-$RANDOM \
 You see the data produced by the first session continuously appear on the screen as output.
 Leave the second session also running.
 6. Click Streams Messaging Manager on the services pane to open the SMM web UI.
 It may take a few minutes for the consumer or producer activity to start showing in the SMM UI. You may have to refresh your page a few times until the data starts to appear.
 Once it does, you see one active producer on the left-hand side of the page and at least one active consumer listed on the right-hand side of the page.
 You also see the LAG metrics listed besides each consumer. This metric indicates the number of messages the consumer is behind the latest message produced to the Kafka topic. You can use this to quickly identify slow consumers that are lagging behind producers.
 7. Click either on the producer or on the consumer, and SMM shows their activity, highlighting all the topics and partitions they are writing to or reading from, respectively.
 In this page you can identify metrics for the overall Kafka topic activity and partition-level. The In Sync Replica (ISR) set for each partition can be identified on the screen. The ID of the LEADER replica for each partition is shown on the left-hand side, while the FOLLOWER replicas are represented as teal-colored boxes on the right-hand side.
 8. Click on an empty part of the page to clear the consumer or producer selection, and then click the profile icon for the machine-data topic.
 This opens the Kafka topic details page where you can find all the topic-related metrics and utilization charts.
 9. Click the DATA EXPLORER tab.
 In the Data Explorer page you can sample the data that is flowing through the Kafka topic. Select different partitions and adjust the offset sliders to become familiar with those controls.

City-Farm Wage Gaps in Late Nineteenth-Century France
Pierre Sicsica1
a1 Centre de Recherche of the Banque de France, 39 rue Croix-des-Petits-Champs, 75001 Paris, France.
Wage gaps between farm and city are used to assess whether industrialization in late nineteenth-century France was choked off by peasants' alleged reluctance to move. If industry suffered due to labor scarcity, wage gaps should have been large and rising. It turns out that the wage gap, when adjusted for costs of living and computed as an average of 20 regional wage gaps, was nil in 1852 and about 25 percent in 1892. Thus wage gaps were rising but were far smaller throughout the late nineteenth century than they were in England during similar stages of industrialization.

This question is a derivative of a previous question: Source control - How to version resources that are shared across projects
I have a project that contains code that is consumed by many other projects. Specifically, one folder in this parent project has been branched to dependent child projects.
We have since made changes in the parent project and checked them in. In Source Control Explorer, I right click on the branched folder in the parent project and select "Merge", intending to push the changes to a dependent project. I select the child project as a destination and then select "Latest Version". The wizard informs me "There are no changes to merge."
From my perspective, this isn't true, since the recently updated files are clearly different.
Is there a fundamental misunderstanding of the merge process in TFS here? What do I need to do differently?

The TFS merge engine relies almost entirely on history, not file contents. This makes it efficient for very large trees, and flexible for tasks like safely cherry-picking changes -- but it also makes answering your question difficult.
The first step is to understand the diagnostic commands tf history, tf merges, and tf merge /candidate. Here is a good introduction:
If you are new to branching & merging in TFS then your history is probably not very complex. I think it's likely you'll find your answer with one quick call to tf merges. However, tracing merge history can become extremely convoluted in the general case, so if you have trouble feel free to post back with more details.
share|improve this answer
Go to one specific file you know has changed in your "parent" project. Try merging just that file. Don't check anything in; just see what happens.
Something to watch for: The merge tools will not include files that have been added after you branch. You have to branch new files explicitly before you can merge any further changes. If a file is added to both parent and child folders without using a branch operation, the merge tools don't treat them as versions of the same file (and you can't merge changes between them).
share|improve this answer
Corrections: * Newly added files do not have a merge relationship with other branches until they're themselves branched = TRUE. (note: can be a "branch, delete") * The workaround is to merge the specific file = FALSE. Won't work. Correct answer is to merge a parent that does have a relationship. * Files added to both branches in parallel will not merge = FIXED IN 2008. See #1-2 from… - but note that if the contents don't match, you're stuck with a version conflict that has no "base" info; merging will be a pain. – Richard Berg Jun 11 '09 at 23:22

Phase plane
From formulasearchengine
Jump to navigation Jump to search
Template:Differential equations
In applied mathematics, in particular the context of nonlinear system analysis, a phase plane is a visual display of certain characteristics of certain kinds of differential equations; a coordinate plane with axes being the values of the two state variables, say (x, y), or (q, p) etc. (any pair of variables). It is a two-dimensional case of the general n-dimensional phase space.
The phase plane method refers to graphically determining the existence of limit cycles in the solutions of the differential equation.
The solutions to the differential equation are a family of functions. Graphically, this can be plotted in the phase plane like a two-dimensional vector field. Vectors representing the derivatives of the points with respect to a parameter (say time t), that is (dx/dt, dy/dt), at representative points are drawn. With enough of these arrows in place the system behaviour over the regions of plane in analysis can be visualized and limit cycles can be easily identified.
The entire field is the phase portrait, a particular path taken along a flow line (i.e. a path always tangent to the vectors) is a phase path. The flows in the vector field indicate the time-evolution of the system the differential equation describes.
In this way, phase planes are useful in visualizing the behaviour of physical systems; in particular, of oscillatory systems such as predator-prey models (see Lotka–Volterra equations). In these models the phase paths can "spiral in" towards zero, "spiral out" towards infinity, or reach neutrally stable situations called centres where the path traced out can be either circular, elliptical, or ovoid, or some variant thereof. This is useful in determining if the dynamics are stable or not.[1]
Other examples of oscillatory systems are certain chemical reactions with multiple steps, some of which involve dynamic equilibria rather than reactions that go to completion. In such cases one can model the rise and fall of reactant and product concentration (or mass, or amount of substance) with the correct differential equations and a good understanding of chemical kinetics.[2]
Example of a linear system
A two-dimensional system of linear differential equations can be written in the form:[1]
which can be organized into a matrix equation:
where A is the 2 × 2 coefficient matrix above, and x = (x, y) is a coordinate vector of two independent variables.
Such systems may be solved analytically, for this case by integrating:[3]
although the solutions are implicit functions in x and y, and are difficult to interpret.[1]
Solving using eigenvalues
More commonly they are solved with the coefficients of the right hand side written in matrix form using eigenvalues λ, given by the determinant:
and eigenvectors:
The eigenvalues represent the powers of the exponential components and the eigenvectors are coefficients. If the solutions are written in algebraic form, they express the fundamental multiplicative factor of the exponential term. Due to the nonuniqueness of eigenvectors, every solution arrived at in this way has undetermined constants c1, c2,... cn.
The general solution is:
where λ1 and λ2 are the eigenvalues, and (k1, k2), (k3, k4) are the basic eigenvectors. The constants c1 and c2 account for the nonuniqueness of eigenvectors and are not solvable unless an initial condition is given for the system.
The above determinant leads to the characteristic polynomial:
which is just a quadratic equation of the form:
("tr" denotes trace) and
The explicit solution of the eigenvalues are then given by the quadratic formula:
Eigenvectors and nodes
The eigenvectors and nodes determine the profile of the phase paths, providing a pictorial interpretation of the solution to the dynamical system, as shown next.
Classification of equilibrium points of a linear autonomous system.[1] These profiles also arise for non-linear autonomous systems in linearized approximations.
The phase plane is then first set-up by drawing straight lines representing the two eigenvectors (which represent stable situations where the system either converges towards those lines or diverges away from them). Then the phase plane is plotted by using full lines instead of direction field dashes. The signs of the eigenvalues will tell how the system's phase plane behaves:
 - If the signs are opposite, the intersection of the eigenvectors is a saddle point.
 - If the signs are both positive, the eigenvectors represent stable situations that the system diverges away from, and the intersection is an unstable node.
 - If the signs are both negative, the eigenvectors represent stable situations that the system converges towards, and the intersection is a stable node.
The above can be visualized by recalling the behaviour of exponential terms in differential equation solutions.
Repeated eigenvalues
This example covers only the case for real, separate eigenvalues. Real, repeated eigenvalues require solving the coefficient matrix with an unknown vector and the first eigenvector to generate the second solution of a two-by-two system. However, if the matrix is symmetric, it is possible to use the orthogonal eigenvector to generate the second solution.
Complex eigenvalues
Complex eigenvalues and eigenvectors generate solutions in the form of sines and cosines as well as exponentials. One of the simplicities in this situation is that only one of the eigenvalues and one of the eigenvectors is needed to generate the full solution set for the system.

Simulation of Interstitial Atom Diffusion in FCC Metals with Point Defects
This work is devoted to simulation of interstitial atom diffusion in fcc metals with point defects. We used the molecular static and the Monte Carlo methods. An activation barrier set for different configurations of the carbon–vacancy complexes is simulated by the method of the molecular static (MS). Then we calculate atom jump rates for these configurations. The simulation of the carbon and vacancy migration in an fcc metal is realized on the basis of obtained atom jump rates by using the Monte-Carlo (MC) method. In particular, the calculations were made for the system of the nickel-carbon. In the result of that interstitial atom diffusion coefficient has been obtained at different temperatures.

How to remove string character using index in Dart
Introduction :
Sometimes we need to remove one character from a string using its index. The string is immutable. We can't modify it. The only way is to create one different new string from the old one.
In this post, I will show you how to remove one character from a string using its index in dart.
How to solve it :
To solve this problem, we will create two substrings from the original string. One from index 0 to just before the character that we are removing and another from the character just after the character that we are removing. We will join these two substrings to get the final required string.
For example, if our string is Helllo and if we want to remove the character at index 2, we will join two substrings: the first one from index 0 to 1 and the second one from index 3 to the end.
substring method :
Generating a substring from a string is easy. Dart provides one method called substring that returns one substring from a string. This method is defined as below :
substring(startIndex, [endIndex])
Here, startIndex is the starting index of the string that we will get the substring from. endIndex is optional. If we don't provide it, it will take the substring to the end of the given string.
Below is the final program :
void main() {
 String givenStr = 'Helllo';
 int i = 4;
 String finalStr = givenStr.substring(0, i) + givenStr.substring(i + 1);
It will print the below output :

How to Brew Smoked Beer: Rauchbiers, Smoked Stouts, and More
Smoked beer can be polarizing. While some people love it, others can't stand it. Is it an acquired taste? Or are there not enough great quality smoked beers available on the market? We're here to shed some light on this often misunderstood area of brewing.
With many breweries reviving this historic style, smoked beer is becoming increasingly popular. Still though, for the best and freshest versions, you'll need to brew it yourself!
How To Brew A Great Smoked Beer
Fans of Scotch, Southern barbecue, smoky bacon, and smoked salmon should all try brewing a smoked beer. And even if you don't love other smoked food and drinks, smoked beer might bring a new and interesting aspect to your brewing repertoire.
What is a Smoked Beer?
Smoked beers refer to all beers with a smoky flavor. No… the beer isn't put in a smoker like making smoked ribs!
Instead, smoked beer is made with malt that has been dried in wood-fired kilns. This malt absorbs the flavor of the burning wood smoke, which is transferred into beer during the mashing process.
Smoked beer comes in a wide range of flavors, styles, strengths, and colors. The one common thread is the use of smoked malt, in varying percentages.
What is Smoked Malt?
Smoked malt is the key to smoked beer. Interestingly, all beer was once brewed with smoked malt. That's because malted barley was exclusively kilned over wood-fired ovens, where the smoke passed through the malt. This imparted that unmistakable smoky taste in all brewer's malt as it dried.
During the industrial revolution, through the 17th century, coal fired kilns began to replace most wood-fired ones. Smoke from the burning coal was diverted to chimneys, and the residual heat produced by the coal was what was used for drying the malt.
Because of this, smoked flavor was eliminated from nearly all malt. Brewers and consumers alike began enjoying the more neutral flavored malts. The shift allowed brewers to have more flexibility in highlighting hop and yeast expression.
Wood smoked malt was relegated to traditional breweries and specialty beers. Today, several maltsters make specialty smoked malt, and some breweries even produce their own. The largest smoked malt producing maltster is Weyermann, in Bamberg, Germany.
Types of Smoked Malt
Smoked malt is usually malted barley, but smoked wheat malt is also fairly common. Malt can be smoked with any type of wood, but the most commonly available are:
 - Beechwood: Traditional and most common type of smoked malt, often sold as Rauch Malt or Rauchmalz. Very smoky but pleasantly balanced.
 - Oak: Rounded and subtle smoke flavor. Often used for smoked wheat production.
 - Cherrywood: Commonly found in the U.S. Balanced smokiness much like beechwood smoked malt.
 - Peat: High smokiness and an almost acrid flavor. This is what Single Malt whisky is made from for that intensely smoked profile.
Smoked Beer Styles
Smoked Marzen
General in name, Rauchbier directly translates to "smoke beer" from German. In Germany, the term Rauchbier refers to all types of beers made with smoked malt. Confusing perhaps, outside of Germany, Rauchbier generally refers to a specific style of beer: smoked marzen.
Smoked marzen is dark, malty, and very smoky but backed by delicious malt sweetness. Hop bitterness is subdued but present, adding to drinkability. It's a marzen, a classic German lager, but made with nearly 100% smoked malt.
The most quintessential smoked beer, Aecht Schlenkerla Rauchbier Märzen, is world-class and a must-drink for any fan of smoked beer.
Smoked Pale Lager
Less common, but equally delicious, are smoked pale lagers, like smoked helles and smoked pilsner. With all of the thirst-quenching and crisp qualities of the base style, the added layer of smoke creates a delicious new dimension.
Brewed with 40 to 60% smoked malt, smoked pale lagers come across exceptionally smoky due to the subtle base malt and hop flavors. Served cold and highly carbonated, there may be no better pairing for barbecued foods like sausages and pulled-pork.
Grodziskie is a historic smoked beer from Poland. Dating back to the 14th or 15th century, the style is a light and refreshing ale brewed with oak-smoked wheat malt. It's very effervescent and bright, with a rounded body and soft mouthfeel from the wheat malt.
At around 3 to 4% ABV, Grozsikie is similar to Belgian grisette, but brewed with 100% oak-smoked wheat malt and fermented with a clean German ale yeast.
Smoked sour ale – certainly not a beer for everyone. You might be surprised by the complex mix of flavors that Lichtenhainer puts forth. The style originates in Thuringia, Germany and is usually brewed with equal parts pilsner malt, wheat malt and smoked malt.
It's light in body, low in alcohol, pale and refreshing, very much like Berliner Weisse, but not quite as tart. The subtle layer of smoke adds to its drinkability and complexity, creating a very unique and quaffable beer.
Smoked Porter and Smoked Stout
Porters and stouts are common candidates to be smokified. Whether you're brewing a session strength porter or a sticky imperial stout, a bit of smoked malt can complement the roasted and chocolatey malt.
When brewing smoked stouts and porters, be sure to retain some residual sweetness. Too dry, black smoked beers can come across burnt tasting. Using an English yeast, like Wyeast 1318 London Ale III, or incorporating some caramel malts can help soften the mouthfeel.
What makes a good Smoked Beer?
Smoked beer can vary widely in style and level of smokiness. Depending on the brewer's vision, beers can range from very subtly smoked to face-in-a-campfire levels. There are no minimum or maximum thresholds for smokiness.
Generally, smoked beer should be balanced. If it's very smoky, malt sweetness and balanced bitterness should complement those intense flavors. For lightly smoked beers, like smoked pilsner or helles, crisp malt backbone and herbal hoppiness is desirable.
For those unaccustomed to smoked beer, it does take some getting used to. Many people directly associate smoked flavors with food – like bacon or smoked ham – which can be a bit mind-bending in the context of beer.
Per Schlenkerla, the masters of smoked beer:
How to brew Smoked Beer
Brewing smoked beer takes experimentation and an ambitious brewing spirit. Using smoked malt, you need to be willing to accept that the beer might come out a little "too much" or "not enough". The more you brew with smoked malt, the more consistent you'll be able to design recipes.
Generally, smoked beers are not overly hoppy. Assertive hop character can clash with smoked flavor, or the smokiness can overwhelm hoppiness. That said, a smoked NEIPA may be possible with the right mix of ingredients – I've certainly been considering experimenting.
Recipe design
Smoked malt can replace a certain percentage of the base malt from most beer recipes. If you have a favorite helles or pilsner recipe, swap out 40 to 50% of the pilsner malt with smoked malt.
Here's a handy guide that can help with smoked beer recipe decisions:
Style Average Smokiness Smoked Malt % Other Malts Yeast
Smoked Marzen (Rauchbier) ⬤⬤⬤⬤⬤⬤⬤⬤◯◯ 90 – 100% CaraMunich (2%), roasted barley (2%) Lager
Smoked Helles ⬤⬤⬤⬤⬤⬤◯◯◯◯ 20 – 50% Pilsner Lager

Lichtenhainer ⬤⬤⬤◯◯◯◯◯◯◯ ~33% Wheat (33%), Pilsner (33%) Lactobacillus and Ale
Recipe: Smoked Pilsner
This is a simple Smoked Pilsner recipe that's a great introduction to the world of smoked brewing. A touch of wheat helps round out the mouthfeel, and a heavy hand of smoked malt comes across smoky but balanced.
It's extremely refreshing and drinkable like a Pilsner, but with a layer of unique smoked complexity.

Write $F_n:=\{x\in \ell^2,\sum_{j=1}^{+\infty}|x_j|\leq n\}$. Then $\ell^1=\bigcup_{n\geq 1}F_n$. $F_n$ is closed in $\ell^2$, as if $\{x^{(k)}\}$ is a sequence which lies in $F_n$ and converges to $x$ in $\ell^2$; we have for an integer $N$ that $$\sum_{j=1}^N|x_j|\leq\lim_{k\to\infty}\sum_{j=0}^N|x_j^{(k)}|\leq n,$$ which gives $x\in F_n$.
$F_n$ has an empty interior in $\ell^2$. Otherwise, if $B_{\ell^2}(x,r)\subset F_n$, then for each $y\in \ell²$, we would have $\frac{r}{2\lVert y\rVert_2}y+x\in F_n$, hence $\frac{r}{2\lVert y\rVert_2}y\in F_{2n}$. This gives that $\lVert y\rVert_1\leq C\lVert y\rVert_2$ for an universal constant $C$, which is not possible.

Lord and Lady are honorifics used to address someone of authority. The exact authority needed is uncertain but seems roughly to be Warlord or higher, with use increasing with formality and the relative rank of the addressee. Being noble isn't a prerequisite for being addresses as either "Lord" or "Lady".
People referred to as Lord/Lady
Erfworlders may erroneously believe that Parson is a Noble unit because they can't see his stats and because he introduced himself to them as "Lord Hamster", which was originally the pen name he used when writing his webcomic.

The difference between an honorific and a title
A honorific is used to preface a person's name as a sign of respect. A title is something a person posses that is not part of their name. People of different rank or title can share the same honorific. If Steward is a Baron he would be addressed as "Lord Steward". Something can be both a title and an honorific (i.e. "Prince") but it does not have to be the case.

I'm comparing Entity Framework with NHibernate, and I'd like to know if when using SQL Server, what effect (if any) would enabling or disabling MARS support have on NHibernate?
MARS = Multiple Active Result Sets
The Entity Framwork documentation states the following:
When you call the Load method during a foreach (C#) or For Each (Visual Basic) enumeration, the Entity Framework tries to open a new data reader. This operation will fail unless you have enabled multiple active results sets by specifying multipleactiveresultsets=true in the connection string. For more information, see Using Multiple Active Result Sets (MARS) on MSDN. You can also load the result of the query into a List collection, which closes the data reader and enables you to enumerate over the collection to load referenced entities.
Does NHibernate has the same issue?

The issue you're referring to is linked to "server side cursors", and as far as I know of nHibernate this shouldn't be an issue, simply because it don't use them.
If you're using LINQ to load objects in nHibernate, on the first access to the foreach enumeration, nHibernate load in memory the whole resultset of the query, and this way it can use the session's connection to load everything else. When using HQL query or Criteria, it will load the resultset when you call "List()" then it close the connection.
Entity framework on the flip side, try to be smart and make use of server side cursors when scrolling a collection via a foreach enumeration, so the objectContext's connection is "busy" with the server side cursor until the foreach enumeration is ended. If MARS is not enabled, EF can't use the connection to load another resultset (you can still issue other statements such update, insert and delete) and thus it will give you an error like "There is already an open DataReader associated with this Command which must be closed first" or something similar.
Hope this helps,
After some research I've found that nHibernate could use MARS, but still in ver there's no driver for SqlServer that supports it. Of course in the SqlClientDriver is not supported (as it is inteded for Sql2000 that has no support for MARS) but even in the Sql2008ClientDriver the relevant property is set to false. Anyway this is something I'll post to the nHibernate team as soon as possible
share|improve this answer
So then does NH not care about MARS at all? What if you try to lazy-load another entity while enumerating an IQueryable result set? Wouldn't that require MARS? Perhaps NH has some way around this, or just doesn't support it? – Matt Johnson Nov 7 '11 at 17:33
Well, I'm tempted to but I can't say that. I've taken a look at nHibernate source and found out that the nHibernate could potentially use MARS. The SqlClientBatchingBatcher is derived from AbstractBatcher which in turn check if "_factory.ConnectionProvider.Driver.SupportsMultipleOpenReaders" then it use an implementaion of IDataReader that make use of MARS (as far as I know just for SQLServer and Oracle). So nHibernate is aware of MARS and looking at the cose seems able to use it for batching, if it is available, however I haven't tried it so far. If you 'll do some test on it, let us know – mCasamento Nov 8 '11 at 13:48
Thanks for looking. I'll do some testing at some point. The concern came up because we are going to (eventually) be using SQL Azure with Federations, and it doesn't support MARS. We chose NHibernate for other reasons, but I'm working on the assumption that it does not require MARS and will still work when not enabled. I'll award you the bounty since yours was the only answer and was at least detailed enough to point me in the right direction. Thanks. – Matt Johnson Nov 8 '11 at 14:54
Glad to be helpful, glad for the points and... Glad you choose nHibernate! I've done the same comparison about 1 year and an half ago, and now I lead a big project with nHibernate. I also help on two other smaller projects developed with EF so I'm up to date with both, and day by day I see that are no other reason that a gentler learning curve to use EF with a real world business application (more than 50 entities) – mCasamento Nov 8 '11 at 20:51
The distinguishing factor for me was that NH can be extended through event listeners. EF had something that could achieve the same effect in CTP5 called "Custom Pluggable Conventions", but they dropped it for the 4.1 release and it hasn't come back yet in 4.2. So NH it is. – Matt Johnson Nov 9 '11 at 14:19

This post contains reasons why you should not laminate certificates and other documents, am sure it will convince you not to ever laminate certificates & documents again.
I was reading through some posts on Nairaland when I saw a question asked by a Nairalander, he wanted to know the "effects of lamination of certificates?" Then, I decided to write about the major disadvantages why you should not laminate certificates and other vital documents.
What Is Lamination?
Lamination is a process whereby thin layers of transparent polythene nylon is joined together to protect paper documents such as certificates, results, testimonials etc.
Why Do People Laminate Certificates?
Here are some important reasons why people seem to laminate their certificates/documents below…
1. Lamination protects paper materials from getting damaged by fluid, dust/dirts, grease and hampered edges.
2. It's believed that lamination elongates the life span of important document like certificates, results and so on.
3. It improves the strength, quality and appearance of the product.
There are more to it but those are the most important reasons why people often opt in for a lamination. A lot of people make believe what isn't supposed to be true. However, laminating certificates, pictures and other paper materials isn't utterly advantageous, there are cons attached to it. Below are reasons you should not laminate certificates & other documents.

Kissing hands
From Wikipedia, the free encyclopedia
 (Redirected from Kiss Hands)
Jump to: navigation, search
This article is about the constitutional term. For the more general ritual of greeting and respect, see Hand-kissing.
To kiss hands is a constitutional term used in the United Kingdom to refer to the formal installation of Crown-appointed British government ministers to their office.
In the past, it referred to the requirement that the office-holder actually kiss the hands of the Sovereign as a symbol of personal fealty and loyalty to the Sovereign, that fealty and loyalty being a requirement to serve in the King's or Queen's government.
In modern times, office-holders are not expected physically to kiss the hands of the Sovereign before assuming the role. Simply being received by the Queen is taken to validate the selection, with this meeting being described in the Court Circular as "kissing hands". The invitation issued to a party leader to form a government is sometimes still described as "an invitation to kiss hands". The actual kissing of hands does not take place until the subsequent meeting of the Privy Council, when the new minister is formally appointed as a member of the Council.[1]
When appointing a Secretary of State (the top rank in the UK government), the protocol also involves the delivery by the Sovereign of the seals of office into the hands of the appointee. This is also valid for other officers who are keepers of seals, such as the Lord Privy Seal or the Lord Chancellor, who is also keeper of the Great Seal of the United Kingdom.
Ordinarily the ceremony will take place in Buckingham Palace, but it has been known to happen in Windsor Castle or Balmoral Castle, and in 1908, King Edward controversially summoned H.H. Asquith to Biarritz, France, where he was on holiday at the time.

Package-Specific Context Entries
This example outlines how to create package-specific context entries.
The Context Panel provides easy clickable access to many commands in Maple. In Maple's user interface, when your cursor is on either input or output for 2-D math expressions (or output from 1-D math expressions), context-sensitive operations can be found in the Context Panel on the right side of the screen.
In order to make sure that as many people as possible can access commands in your package, it is important to consider adding one or more of your commands to the context-sensitive infrastructure. The following example will show you how that's possible.
First, start with a package that you have authored.
Here is a quick example of a package module that has three exports:
squared: a procedure that takes an integer and squares it
cubed: a procedure that takes an integer and cubes it
parsestring: a procedure that takes a string and attempts to parse it
Here is the output of the package exports.
Adding Context Panel Entries
There are several important parts of building individual entries for the context panel.
Most importantly, you want to know:
WHAT to call the entry; the label to show in the context panel
WHICH command you want to use; the command to apply when the label is clicked
WHEN to show the entry; under what type conditions the option is shown
HOW you will help the user use it; the tooltip to help describe what the command does
The command to add an entry to the current context-sensitive infrastructure is called ContextMenu:-CurrentContext:-Entries:-Add.
Here is a short example of using the command where you add an entry to the context panel that negates a boolean value:
"Negate", _TAG_ to show
"not %EXPR", _TAG_ to apply
boolean, _TAG_ conditions
'helpstring'="Negate the expression"): _TAG_ to show
Try clicking on the output below and using the "Negate" option from the context panel.
Using "Negate" gives the following:
The most important part of specifying a context panel entry is determining WHEN to show it. Typically, you should try to show context-sensitive entries whenever Maple detects input that is of the same type as is expected for your routines. For example, the above module expects type integer for the procedures squared and cubed, and type string for the procedure parsestring.
Here is another example using the module above. In this example, you will add a new entry called "Square" that is shown for an integer input.
"Square", _TAG_ to show
":-MyPackage:-squared(%EXPR)", _TAG_ to apply
integer, _TAG_ conditions
'helpstring'="Square the expression"): _TAG_ to show
Click on the output below, then use the "Square" option from the context panel.
Using "Square" gives the following:
Since the example for cubed will be similar to squared, you can skip that and do one more example for the parsestring procedure.
"Parse string", _TAG_ to show
":-MyPackage:-parsestring(%EXPR)", _TAG_ to apply
string, _TAG_ conditions
'helpstring'="Parse the string"): _TAG_ to show
Adding Context Panel Entries to a Package
Next, add the entries for each of the procedures created above to the code for the package module. For a package implemented as a module, new and relevant context-sensitive entries can be created inside the module's ModuleLoad export; this will cause the new context panel entries to be automatically created upon the first invocation or use of the package.
Before adding the entries for the procedures to the package module, make a copy of the current context panel. You can now freely customize the copied panel.
Note: The added entries will not be visible in the Maple context panel until you execute the Install command.
pCM := ContextMenu:-CurrentContext:-Copy():
Queries can be useful while determining when to show your context-sensitive items. New context panel entries can be configured so as to only appear under specific circumstances - such as when the package is loaded (using with).
Add a query to test if your package is loaded or not:
"Is MyPackage Loaded",
member( ':-MyPackage', packages() );
The AddMultiple command adds multiple entries in one call:
'helpstring'="Square the expression" ],
'helpstring'="Cube the expression" ],
[ "Parse string",
'helpstring'="Parse the string"],
'submenu'=["MyPackage"], _TAG_ a sub-folder for MyPackage
'active'="Is MyPackage Loaded"); _TAG_ active option tests whether some condition is met( i.e. if "Is MyPackage loaded"? );
The Install command adds the entries to the context panel:
Next, load the package to activate the entries:
Finally, you can put this together in the original procedure, creating a package that contains its own context-sensitive panel code. In order for the context-sensitive code to be available when a package is run, it is required that the code for the actions are added to the ModuleLoad section of the module. If a ModuleLoad local or export is present, then this procedure is called when the module is read from the Maple repository in which it is located (in the code below, this is done manually by calling ModuleLoad() ).
When MyPackage is loaded, the ModuleLoad section is initialized, making the commands available in the context-sensitive system.
Thus, clicking on 3 now shows a submenu for "MyPackage" as well as several available commands.
There are more examples that discuss package authoring and context panels in Maple, including:

The motivation behind the world's fastest electric ice cream van
What motivates an inventor and entrepreneur to design the world's fastest ice cream van? Edd China, a British inventor and TV presenter from Surrey, has broken the Guinness World Record by creating an ice-cream that clocked up speeds of 73.921 mph. Although he doesn't sell ice-cream for a living, he is on a mission to decrease carbon emissions and demonstrate that businesses aren't negatively impacted by embracing electric vehicle technology.
This is Edd's seventh Guinness World Record title centred around speedy motorised vehicles, but the project was never about just breaking records. After Edd discovered that ice cream vans were being banned in some London boroughs due to their harmful emissions, he decided to create a special engine conversion kit that can run on electricity rather than diesel. He hopes to roll it out as a business, and in doing so, to future-proof ice cream vans as a key part of the British summer.
The van originally ran on a Mercedes Sprinter diesel engine. After two years of modifications the record was broken at Elvington Airfield in Yorkshire with a speed which would have warranted a speeding ticket on a motorway.
What's next for the inventor? He has his sights set on breaking the record for the fastest motorized shopping trolley currently held at 70.4 mph and to make it street legal.
Other notable records involving automobiles include:
The longest journey by a coffee-powered car
In 2010, a Volkswagon Scirocco was driven 337 km from London to Manchester powered by coffee. The modified car works by heating coffee granules in a charcoal fire, which break down into carbon monoxide and hydrogen. 'Car-puccino' can reportedly reach 60 mph and achieved 1 mile per 56 espressos. The process works because coffee granules contain a small amount of carbon.
The fastest police car in service
To help them keep up with rich businessmen in their speeding sports cars, police in Dubai decided to invest in one of the most powerful production cars on the planet: a Bugatti Veyron. With a blistering top speed of 253 mph and a US$1.6 million price tag, the Dubai police parked the Veyron alongside a Lamborghini Aventador that they already owned. The Veyron, however, was renowned in 2016 as the second fastest street-legal car in the world, only pipped by the 301 mph Hennessey Venom GT.

Meat Grinders
How to Use Meat Grinder
how to use meat grinder
It is easy to use the best meat grinder; assemble the grinder, place your meat on the plate, feed it down the hopper and then turn on the grinder. You then choose the speed you want the meat to be ground at, for KitchenAid, 6 to 8 is an ideal speed. You will be collecting your ground meat within no time. However, there are a few other things that are equally important. Here are some vital tips on:
How to Use Meat Grinder:
1. Keep Everything Cold
Keep everything cold
This is one very important consideration. Warm meat is bad for your grinder as it will smear, the fats leak out as well as have a cooked, pulpy and dry texture. To avoid this, ensure that your grinder spends an hour in the freezer before using it. Let you meat be well chilled up to the minute you start to grind it. For sausage meat which entails several grinds, place the ground meat into a bowl that is placed in another ice-filled bowl. This is to keep it well chilled.
2. Trim Your Meat
trim your meat
Smearing happens when the blade gets into contact with sinew thus making the blade become dull. The blade smooshes meat through the holes instead of cutting it. This results in a chewed up texture thus is in no way appealing. Therefore, trim your meat well
3. Look Out For Smearing
Smearing is visible and can, therefore, see it and correct it. Pieces of meat usually pass through the holes on the plate. In case you see both meat and fat coming out in one batch and often look wet and sticks on to the die surface, know that all is not well. Use the "reverse" function to fix the grinder if your grinder has one. Alternatively, disassemble the grinder, clean the blade and restart it.
4. Maintain a Sharp Blade
Maintaince sharp balde
The blade is one part that needs your attention. You shouldn't let it become dull as it will smear meat. However, you should know that most blades get better with repeated use. This is because of the microscopically grinding down of the metal thus making the contact between the plate and the blade tighter after every use. In case your blades become dull, sharpening them maybe once a year would be ideal to keep them in top-notch. You can as well opt to replace the blades once in a while.
5. Large To Small Plate
In case you need the very fine grind for your sausages, grinding the meat twice is the way to go. Start with the ¼-inch plate, chill the meat again and then grind it using the smaller die. This will not only produce finer pieces of meat but also avoid smearing. The more even grind will result in a fine-textured sausage.
6. Salt Meat before Grinding
salt meat before grinding
Salt dissolves some proteins and enables them to cross-link easier into a tight matrix resulting in the springier texture common in sausages.
Now you know that the best meat grinder doesn't always give you the best ground quality just like that. You need to take great care so that you don't compromise on the texture and quality of the ground meat.

Aerocene Explorer Tethered flight at Mobile Utopia Conference
2 November 2017
54°00'21.0″N 2°47'15.0″W
On November 2nd Sasha Engelmann, Bronislaw Szerszynski and Grace Pappas performed an Aerocene Explorer tethered flight in Lancaster, UK, within the framework of a two-day "Mobile Utopia Experiment" called "The Drift Economy", that Bron and Sasha co-organized. The Drift Economy workshop was held at the Lancaster City Library on November 1st, and at the Lancaster University InfoLab on the morning of the 2nd. Participants joined Bron and Sasha in experimenting with drifting seeds, VR-experiences of drift, and 'mapping drift' onto a three dimensional diorama of Lancaster's topography. The Drift Economy was an experiment in public participation in an alternative mobility regime based on the existing flows of water, air, slopes, soil and elemental processes.
Aerocene was a primary element in the Drift Economy experiment, as well as in the conference session and panel that Bron and Sasha chaired at the Mobile Utopia Conference.
In the context of the continuing expansion of fuel-intensive air travel and the militarization, securitization and commercialization of atmospheric space, the experimental workshop and the conference session were devoted to exploring how humans might develop an ethical and sustainable relationship with the atmosphere through vernacular ways of sensing, understanding and collaborating with the macroand micro-dimensions of air.
The approach to critical atmospheric utopias was inspired by Aerocene, inviting a tactile, unmediated skilling of atmospheric awareness. In its name, Aerocene also deliberately evokes the possibility of an epochal shift in humanity's relation with its home planet, and indeed in the very way that the Earth populates its atmosphere with moving things.
At around noon on the 2nd of November, Grace and Sasha inflated the sculpture on an open field near the conference venue. As they were attaching the GPS tracker to the Aerocene sculpture, Rob La Frenais joined them on his bike. Later in the conference, during his Keynote speech, Rob spoke about the Aerocene flight that had happened that day, and related it to the White Sands launch of D-OAEC Aerocene that occurred in 2015.
Luckily for the launch team, the weather was particularly benign on that day -except for a little wind – and the Aerocene Explorer floated in the atmosphere immediately, while recording track information with a handheld GPS attached to it. Sasha and Grace took turns flying the sculpture, and then Sam Hertz, who had just arrived at the conference, flew the Aerocene with Bron.
The Sculpture flew over an hour, overseen by over 60 people who gathered for the launch, registering a complicated aero-glyphic that was later processed with Garmin Basecamp and Google Earth into a striking visualization. Participants connected to the Aerocene Explorer wifi hotspot and connected to the Aerocene's onboard camera to 'see' what the sculpture was seeing. During her train travel back to London that evening, and on the way back up to Lancaster the following morning, Sasha downloaded the flight data from the launch and made some early attempts at a Google Earth flight visualization with the help of Joaquin.
The experience of the Aerocene launch resonated into the conference session during the following days. The "Atmospheric Adventures in the Aerocene: heterotopias of aerial mobility" conference panel on the 3rd November included presentations by Bron, Sasha and Sam Hertz. It also included a short film, "Points of Presence" made by Adam Fish, Bradley Garrett and Oliver Case. Rob La Frenais was the 'discussant'. The panel was guided by the following questions:
 - How can we invent and employ accessible, modest aerial experiments to arrive at an ethical engagement with the atmosphere?
 - What tools, skills, imaginaries and alliances do we need to develop to become more sensitive to the objects and vibrations passing through the atmosphere around us?
 - How can we populate the air in ways that enhance rather than diminish atmospheric affordances for different forms of life?
The response from the panel and the subsequent discussions with many scholars, researchers, artists, technologists and engineers was a clear indication of the way that the Aerocene launch and the panel discussion had catalyzed a range of reflections and insights at the Mobile Utopia conference. Indeed, many commented that it was the most expressive, ethical and collective 'mobile utopia' among the countless other proposals circulating in the air in Lancaster.
Sasha Engelmann would like to thank the Aerocene foundation for lending the sculpture to Aerocene friends in the U.K., Bron for coordinating their amazing Drift Economy experiment in Lancaster, Daniel Schulz for preparing the Explorer and checking all the components with Sasha during the summer, and Joaquin who was a fantastic (!) help with the Garmin device & software. Also Grace traveled over two hours from London to join the launch on that day and was incredibly super helpful in flying, communicating and documenting the Aerocene project to everyone involved.
