Strategy design pattern
published by Pradeep on April 22, 2018
This article will explain the strategy design pattern using functional interfaces. Sometimes application may need to execute an algorithm conditionally. Here the algorithm means nothing but a strategy, execution of this strategy depends on runtime conditions or it depends on the input received from the user. For example, sorting a list of persons can be a strategy and a type of the sorting can depend on age or name, Encrypting a string can be strategy and this strategy can depend on the type like RSA or Blowfish.
We can conditionally execute algorithms based on the if or switch conditions like below
public class EncryptClient {
static String encryptMessage(String type, String input){
//to shorten the code this method just converts the case of the input
if(type.equals("RSA"))
return input.toUpperCase();
else if(type.equals("Blowfish"))
return input.toLowerCase();
return input;
}
public static void main(String[] args) {
System.out.println(EncryptClient.encryptMessage("RSA","teXt"));
}
}
The problem with the above code is, EncryptClient class needs to modified for every new algorithm added. Also modification needed, if name of the type changes. This is not a good design.
Strategy design pattern
Instead of executing algorithm conditionally we use an interface to define the strategy.
public class EncryptClient {
static String encryptMessage(EncryptionStrategy es, String input){
return es.encrypt(input);
}
public static void main(String[] args) {
System.out.println(EncryptClient.encryptMessage(new RSAEncryption(),"teXt"));
}
}
interface EncryptionStrategy{
public String encrypt(String input);
}
class RSAEncryption implements EncryptionStrategy{
@Override
public String encrypt(String input){
//to shorten the code this method just converts the input to upper case
return input.toUpperCase();
}
}
class BlowFishEncryption implements EncryptionStrategy{
@Override
public String encrypt(String input) {
//to shorten the code this method just converts the input to lower case
return input.toLowerCase();
}
}
We created an interface (EncryptionStrategy) and implemented it for each algorithm. Note that the implementation classes are not actually encrypting the input but instead converting the case of the input characters, this is to reduce the code size, in real word application it should call a method which contains real algorithm. Instead of passing the name of the algorithm we passed the implementation to encryptMessage method. No more if conditions are needed in encryptMessage method because it receives the EncryptionStrategy as one of the parameter so it just uses it. In future we can create new class for new algorithm which implements EncryptionStrategy and there will be no change needed in encryptMessage method. We further optimize and improve the code using static interface methods, which will be explained in below section.
Strategy pattern with static interface methods
Another approach to implement strategy pattern is using static methods in the interface, this way, instead of creating new class for each implementation we have to create new static method in the interface. This will help us to have less number of classes. Static methods in interface are introduced in Java 8.
public class EncryptClient {
static String encryptMessage(EncryptionStrategy es, String input){
return es.encrypt(input);
}
public static void main(String[] args) {
System.out.println(EncryptClient.encryptMessage(EncryptionStrategy.getRSAStrategy(),"teXt"));
}
}
interface EncryptionStrategy{
public String encrypt(String input);
static EncryptionStrategy getRSAStrategy(){
//returns lambda, which implements encrypt method of EncryptionStrategy
return input -> input.toUpperCase();
}
static EncryptionStrategy getBlowFishStrategy(){
return input -> input.toLowerCase();
}
}
getRSAStrategy and getBlowfishStrategy returns the lambda which implements the EncyrptionStrategy interface.
Strategy pattern with functional interfaces.
We can improve and optimize this code even more by utilizing functional interfaces. If you observe the EncryptionStrategy interface, it is having a single method which is encrypt, this method accepts and returns String. This is how the UnaryOperator interface in java.util.function package works. UnaryOperator accepts and returns the same type. Java provided some standard functional interfaces, we can utilize these interfaces instead of creating new ones.
public class EncryptClient {
static String encryptMessage(UnaryOperator<String> es, String input){
return es.apply(input);
}
public static void main(String[] args) {
System.out.println(
EncryptClient.encryptMessage(
input -> input.toUpperCase(),"teXt"));
}
}
We no more need any custom interface, instead we can use UnaryOperator because it accepts and returns same type. EncryptionStrategy is doing the same thing so instead of using this interface we can reuse exiting functional interfaces. Caller of encryptMessage is passing the lambda which is the implementation on UnaryOperator. This lambda is just passing the case conversion logic but in real world application caller will pass the real call to the algorithm, this is to just make code smaller for this article purpose.
Conclusion
We have seen how strategy design pattern works and multiple ways to design it in the Java.

Say you are working on a paper. You¡¯ve gotten a first draft out, submitted for review. You then get a new batch of data, and you¡¯re in the process of integrating it into the paper. Halfway in, however, the review committee calls you up and tells you that you need to change some of your section headings to conform to format specifications. What do you do?
Obviously you don¡¯t want to send them your half-baked revisions with corrected headings. What you want to do is jump back to the version you sent out, change the headings on that version, and send off that copy, all the while keeping your recent work safely stored somewhere else
This is the idea behind branching, and Git makes it easy to do.
Note on terminology: The terms ¡°branch¡± and ¡°head¡± are nearly synonymous in Git. Every branch is represented by one head, and every head represents one branch.
To create a branch, say your repository looks like this:
(A) <-- (B) <-- (C) | master | HEAD
Where (B) was the version you sent to the conference and (C) is your new version.
Now, we use the git branch
command:
git branch [new-head-name] [reference-to-(B)]
or, for example:
git branch fix-headers HEAD^
Now our commit tree looks liks this:
(A) <-- (B) <------(C) | | fix-headers master | HEAD
In order to start working to headers, you need to set the fix-headers to be the
current head. This is done with git checkout
:
git checkout [head-name]
This commands does the following:
Important note: if there are any uncommitted changes when you run git checkout, Git will behave very strangely. The strangeness is predictable and sometimes useful, but it is best to avoid it. All you need to do, of course, is commit all the new changes before checking out the new head.
After checking out the fix-headers head, you fix the headers. Now you add and commit the changes as above. The resulting repository looks like this:
<------------------(D) / | (A) <-- (B) <------(C) | | | master fix-headers | HEAD
Other useful commands at this point:
git branch
with no arguments lists the existing heads, with a star next
to the current head.
git diff [head1]..[head2]
shows the diff between the commits referenced
by head2 and head1.
git diff [head1]...[head2]
(three dots) shows the diff between head2
and the common ancestor of head1 and head2. For example,
diff master...fix-headers
above shows the diff between (D) and (B)
git log [head1]..[head2]
shows the change log between head2 and the
common ancestor of head1 and head2. With three dots, it also shows the
changes between head1 and the common ancestor. This is not so useful.
(Switching head1 and head2, on the other hand, is very usefull.)

An Oscillating Electron Around a Ring of Charge (Part 1)
Introduction
This week in class, my students were trying their hand at solving for the electric potential and electric field from continuous charge distributions. It was the first time that many of them actually applied integrals to a physical setup. In the spirit of continuous charge distributions, I want to go over an example that was done in class and take it a step further.
First, I will derive the equation for the electric field along the axis of a ring of charge. Then, I will take the limit of the ring radius being much greater than the position along the axis. Finally, I will use that result to calculate the equation of motion for an electron released near the center of the ring.
Electric Field Along the Axis of a Charged Ring
This derivation can be found all over the internet. I will quickly go through it here, just to set up the problem. Suppose I have a ring with total charge \(Q\) and radius \(R\). I want to find the electric field at some distance \(z\) along the z-axis as shown in the diagram below.
We can start by writing out Coulomb’s law for continuous charge distributions.
\[\begin{equation} d\vec{E} = \frac{k dQ}{r^2} \hat{r} \end{equation}\]Let’s start by solving for dQ in the equation above. As shown in the diagram, we cut the ring up into tiny little pieces. Each piece has a tiny charge dQ. If we define the charge density of the ring as \(\lambda = Q/2\pi R\) - the total charge of the ring divided by the total circumference of the ring - we can rewrite dQ in terms of charge density (\(\lambda\)) and arc length (\(ds\)).
\[\begin{equation} dQ = \lambda ds \end{equation}\]I personally like to integrate with respect to angle \(\theta\) rather than arc length. Thus, we can use the relationship between angle (\(d\theta\)) and arc length (\(ds\)) to expand the equation above.
\[\begin{equation} ds = R d\theta \end{equation}\] \[\begin{equation} dQ = \lambda R d\theta \end{equation}\]Next, we can solve for \(r^2\). This is particularly easy in this example - every tiny piece \(dQ\) along the ring is equidistant from the point some distance along the z-axis. We can calculate this distance using the Pythagorean theorem.
\[\begin{equation} r^2 = z^2 + R^2 \end{equation}\]Finally, we can solve for the unit vector \(\hat{r}\). In this case, we notice that all of the horizontal components of the electric field will cancel out, leaving only the vertical componenets. Thus, we can use the cosine function to get just the vertical component of the field.
\[\begin{equation} \hat{r} = cos\alpha \hat{z} \end{equation}\]We can rewrite the cosine in terms of z and R.
\[\begin{equation} cos\alpha \hat{z} = \frac{z}{r} \hat{z} = \frac{z}{\sqrt{R^2 + z^2}} \hat{z} \end{equation}\]Putting everything together gives us an expression for \(dE\) (now called \(dE_z\) to signify that the field points along the z-axis).
\[\begin{equation} dE_z = \frac{k z \lambda R d\theta}{\left (z^2 + R^2 \right )^{3/2}} \end{equation}\]I am will integrate this expression over the entire ring (angle 0 to \(2\pi\)).
\[\begin{align} E_z &= \int_0^{2\pi} \frac{k z \lambda R d\theta}{\left (z^2 + R^2 \right )^{3/2}}\\[0.1cm] &= \frac{k z \lambda R}{\left (z^2 + R^2 \right )^{3/2}} \int_0^{2\pi} d\theta\\[0.1cm] &= \frac{k z \lambda R}{\left (z^2 + R^2 \right )^{3/2}} \left ( 2\pi \right ) \end{align}\]We can simplify the charge density with the circumference (\(2\pi R\)) to get the final answer.
\[\begin{equation} E_z = \frac{k Q z} {\left (z^2 + R^2 \right )^{3/2}} \end{equation}\]Small Distance (z)
Suppose we are only interested in the electric field very close to the center of the ring. In other words, \(R \gg z\). Then, the \(R^2\) term in the denominator would completely dwarf the \(z^2\) term in the denominator. Thus, we can simplify the expression further for small distances (small z) by dropping \(z\) in the denominator.
\[\begin{equation} E_z \approx \frac{k Q z} {\left (0 + R^2 \right )^{3/2}} \end{equation}\] \[\begin{equation} E_z \approx \frac{k Q z} {R^3} \end{equation}\]Notice how this expression in linear with respect to \(z\) since \(k\), \(Q\), and \(R\) are all constants.
Oscillations About the Center of the Ring
An electron that is released very close to the center of a positively charged ring (along the z-axis) will feel a restoring force that we described above. Thus, it will oscillate about the center of the ring. We can actually calculate the frequency at which it oscillates. Start with Newton’s second law:
\[\begin{equation} \vec{F} = m\vec{a} \end{equation}\]In this case, the force \(\vec{F}\) is the force of the ring on the electron (i.e. the field \(E_z\) multiplied by the charge of an electron \(e\)). I will write the acceleration \(\vec{a}\) using dot notation (\(\ddot{z}\)).
\[\begin{equation} -\frac{k Qe }{R^3}z = m \ddot{z} \end{equation}\] \[\begin{equation} m \ddot{z} + \frac{k Qe }{R^3}z = 0 \end{equation}\] \[\begin{equation} \ddot{z} + \frac{k Qe }{mR^3}z = 0 \end{equation}\]As we expect, this is simply the equation for oscillatory motion! We can let \(\omega^2 = kQe/mR^3\) to see it more clearly.
\[\begin{equation} \ddot{z} + \omega^2 z = 0 \end{equation}\]The solution to this differential equation is our well known sum of a sine and cosine.
\[\begin{equation} z(t) = Asin(\omega t) + Bcos(\omega t) \end{equation}\] \[\begin{equation} z(t) = Asin \left (\sqrt{\frac{k Qe }{mR^3}} t \right ) + Bcos \left (\sqrt{\frac{k Qe }{mR^3}} t \right ) \end{equation}\]Conclusion
It’s nice to see the formula for oscillatory motion pop up again in introductory electromagnetism. It means that all of the stuff that we learned in mechanics is still valid! Next week, we will look a bit deeper at how to improve this equation of motion by taking into account the self-force - the force that an accelerating charge feels due to the fact that it radiates.
Until next week!

#include <pwd.h> int getpwent_r(struct passwd *pwbuf, char *buf,
size_t buflen, struct passwd **pwbufp); int fgetpwent_r(FILE *fp, struct passwd *pwbuf, char *buf,
size_t buflen, struct passwd **pwbufp);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
getpwent_r(),
_BSD_SOURCE || _SVID_SOURCE
fgetpwent_r():
_SVID_SOURCE
The passwd structure is defined in <pwd.h> as follows:
struct passwd { char *pw_name; /* username */ char *pw_passwd; /* user password */ uid_t pw_uid; /* user ID */ gid_t pw_gid; /* group ID */ char *pw_gecos; /* user information */ char *pw_dir; /* home directory */ char *pw_shell; /* shell program */ };
For more information about the fields of this structure, see passwd(5).
The nonreentrant functions return a pointer to static storage, where this static storage contains further pointers to user name, password, gecos field, home directory and shell. The reentrant functions described here return all of that in caller-provided buffers. First of all there is the buffer pwbuf that can hold a struct passwd. And next the buffer buf of size buflen that can hold additional strings. The result of these functions, the struct passwd read from the stream, is stored in the provided buffer *pwbuf, and a pointer to this struct passwd is returned in *pwbufp.
struct passwd * getpwent_r(struct passwd *pwd, char *buf, int buflen);
or, better,
int getpwent_r(struct passwd *pwd, char *buf, int buflen, FILE **pw_fp);
#define _GNU_SOURCE #include <pwd.h> #include <stdio.h> #define BUFLEN 4096 int main(void) { struct passwd pw, *pwp; char buf[BUFLEN]; int i; setpwent(); while (1) { i = getpwent_r(&pw, buf, BUFLEN, &pwp); if (i) break; printf("%s (%d)\tHOME %s\tSHELL %s\n", pwp->pw_name, pwp->pw_uid, pwp->pw_dir, pwp->pw_shell); } endpwent(); exit(EXIT_SUCCESS); }

<EMAIL_ADDRESS>Good Day
Mr. A.G. Furness
Branch Manager
Bank of Cyprus
London Branch
Dear Friend,
I am Mr. A.G Furness The Branch Manager of the Bank of Cyprus, London. I have an urgent and very confidential business proposition for you.In December, 2001, an American Oil consultant/contractor Mr.Jeffrey Paul Mead made a numbered time (Fixed) Deposit for Twenty-Four calendar months, valued at US$25,000,000.00 (Twenty- five Million Dollars) in my branch.
Upon maturity, I sent a routine notification to his forwarding address but got no reply. After some months, we sent a reminder and finally I discovered from his contract employers, that Mr.Jeffrey Paul Mead passed away.
On further investigation, I found out that he died without making a WILL,and all attempts to trace his next of kin was fruitless. I therefore made further investigation and discovered that Mr. Mead did not declare any kin or relations in all his official documents, including his Bank Deposit paperwork in my Bank. This sum of US$25,000,000.00 is still sitting in my Bank and the interest is being rolled over with the principal sum at the end of each year.No one has ever come forward to claim it.
According to Banking Law, at the expiration of 5 (five) years, the money will revert to the ownership of Government if nobody applies to claim the fund. Consequently, my proposal is that I will like you to stand in as the next of kin to Mr.Jeffrey Paul Mead so that the fruits of this old man's labour will not get into the hands of some corrupt government officials.
This is simple, I will like you to provide immediately your full names and address so that the Attorney will prepare the necessary documents and affidavits which will put you in place as the next of kin. We shall employ the services of two Attorney for drafting and notarization of the WILL and to obtain the necessary documents and letter of probate/administration in your favour for the
transfer.
A bank account in any part of the world which you will provide will then facilitate the transfer of this money to you as the
beneficiary/next of kin. The money will be paid into your account for us to share in the ratio of 60% for me and 30% for you and 10% be used in settling taxation and all local and foreign expenses.
There is no risk at all as all the paperwork for this transaction will be done by the Attorney and my position as the Branch Manager guarantees the successful execution of this transaction.
If you are interested, please reply immediately to my alternative email address above and below and upon your response, I shall then provide you with more details and relevant documents that will help you understand the transaction.
Please observe utmost confidentiality, and be rest assured that this transaction would be most profitable for both of us because I shall require your assistance to invest my share in your country. I can be reached through this email address.
I do urgently await your response.
Best regards,
Mr. A.G. Furness
Kindly send all correspondence to<EMAIL_ADDRESS>- cyprus bank

Libgloss uses an autoconf based script to configure. Autoconf scripts are portable shell scripts that are generated from a configure.in file. Configure input scripts are based themselves on m4. Most configure scripts run a series of tests to determine features the various supported features of the target. For features that can't be determined by a feature test, a makefile fragment is merged in. The configure process leaves creates a Makefile in the build directory. For libgloss, there are only a few configure options of importance. These are –target and –srcdir.
Typically libgloss is built in a separate tree just for objects. In this manner, it's possible to have a single source tree, and multiple object trees. If you only need to configure for a single target environment, then you can configure in the source tree. The argument for –target is a config string. It's usually safest to use the full canonical opposed to the target alias. So, to configure for a CPU32 (m68k) with a separate source tree, use:
../src/libgloss/configure --verbose --target m68k-coff
The configure script is in the source tree. When configure is invoked it will determine it's own source tree, so the –srcdir is would be redundant here.
Once libgloss is configured, make
is sufficient to build it. The
default values for Makefiles
are typically correct for all
supported systems. The test cases in the testsuite will also built
automatically as opposed to a make check
, where test binaries
aren't built till test time. This is mostly cause the libgloss
testsuites are the last thing built when building the entire GNU source
tree, so it's a good test of all the other compilation passes.
The default values for the Makefiles are set in the Makefile fragment merged in during configuration. This fragment typically has rules like
CC_FOR_TARGET = `if [ -f $${OBJROOT}/gcc/xgcc ] ; \ then echo ${OBJROOT}/gcc/xgcc -B${OBJROOT}/gcc/ ; \ else t='${program_transform_name}'; echo gcc | sed -e '' $$t ; fi`
Basically this is a runtime test to determine whether there are freshly
built executables for the other main passes of the GNU tools. If there
isn't an executable built in the same object tree, then
transformedthe generic tool name (like gcc) is transformed to the
name typically used in GNU cross compilers. The names are
typically based on the target's canonical name, so if you've configured
for m68k-coff
the transformed name is m68k-coff-gcc
in
this case. If you install with aliases or rename the tools, this won't
work, and it will always look for tools in the path. You can force the a
different name to work by reconfiguring with the
--program-transform-name
option to configure. This option takes a
sed script like this -e s,^,m68k-coff-,
which produces tools
using the standard names (at least here at Cygnus).
The search for the other GNU development tools is exactly the same idea.
This technique gets messier when build options like -msoft-float
support are used. The Makefile fragments set the MUTILIB
variable, and if it is set, the search path is modified. If the linking
is done with an installed cross compiler, then none of this needs to be
used. This is done so libgloss will build automatically with a fresh,
and uninstalled object tree. It also makes it easier to debug the other
tools using libgloss's test suites.

The U.K. has voted to leave the European Union by a 52 percent to 48 percent margin, the BBC and others predict.
—In a historic vote, the United Kingdom has voted to leave the European Union by a 52-percent-to-48-percent margin, according to forecasts from the BBC, ITV, and others.
—The stunning move raises major questions not only about how the U.K. will extricate itself from the 28-member bloc and the relationship it will have with it, but also about the future of British Prime Minister David Cameron’s government, of the country itself, and of the EU, post-World War II Europe's most ambitious political experiment.
—Polls were tight ahead of Thursday's referendum, but as the votes rolled in, the "leave" side performed better than expected in places it was supposed to win and triumphed in locations it was not. The "remain" side, despite the establishment's optimism, could never catch up.
—The pound slid to a 31-year low against the dollar on the news, and stock futures are sharply lower. Traders were expecting a bloodbath when European markets open.

Drone (Unmanned Aerial Vehicle, UAV)
A drone, in a technological context, is an unmanned aircraft. Drones are more formally known as unmanned aerial vehicles (UAVs) or unmanned aircraft systems (UASes). Essentially, a drone is a flying robot. The aircrafts may be remotely controlled or can fly autonomously through software-controlled flight plans in their embedded systems working in conjunction with onboard sensors and GPS.
In the recent past, UAVs were most often associated with the military, where they were used initially for anti-aircraft target practice, intelligence gathering and then, more controversially, as weapons platforms. Drones are now also used in a wide range of civilian roles ranging from search and rescue, surveillance, traffic monitoring, weather monitoring and firefighting to personal drones and business drone-based photography, as well as videography, agriculture and even delivery services.


What you need to know about Slush 2019 – The world’s largest startup-tech event
by Carien PretoriusThe world’s leading startup and tech event Slush is just around the corner, and will take place in Helsinki, Finland on 21-22 November.
The event brings together 25,000 curious minds, including 4,000 startups and 2,000 investors, at the Helsinki Expo and Convention Centre – with the aim of building a worldwide startup community.
Slush is a student-driven, not-for-profit movement which is organised by over 2,000 volunteers and was founded to change attitudes toward entrepreneurship.
Today, it provides delegates with the ideal platform to meet and discuss opportunities through events such as matchmaking, pitching competitions, and exhibitions.
The line-up for the two-day event includes highly-acclaimed speakers from companies such as Stripe, Giphy, and Masterclass who are experts in their fields.
The foundation
According to Slush, what started as a gathering of 300 local founders in 2008 has become a community of truly global magnitude.
The mission of Slush remains the same, however: to create and help catapult the next generation of ground-breaking entrepreneurs.
Slush also hosts smaller gatherings from Singapore to New York, and other large events in Finland, Japan, and China – all in the name of uniting tech communities to solve the most meaningful problems of our time.
With only two days to go until the main event, investors and start-ups from all over the world – including from Southern Africa – have already started connecting through side events which have been organised for the week leading up to Slush.
To find out more about this exciting event, visit the Slush website.
Carien Pretorius is a guest of Slush in Helsinki, Finland.

In case of overdose, get medical help or contact a Poison Control center right away.
colloidal silicon dioxide, corn starch, lactose monohydrate, magnesium stearate, potato starch, talc
Plan B One-Step® is emergency contraception that helps prevent pregnancy after birth control failure or unprotected sex. It is a backup method of preventing pregnancy and should not be used as regular birth control.
Plan B One-Step® will not work if you are already pregnant and will not affect an existing pregnancy. Plan B One-Step® will not protect you from HIV infection (the virus that causes AIDS) and other sexually transmitted diseases (STDs).
The sooner you take emergency contraception, the better it works. You should use Plan B One-Step® within 72 hours (3 days) after you have had unprotected sex.
Plan B One-Step® is a backup or emergency method of birth control you can use when:
Plan B One-Step® should not be used:
Plan B One-Step® is one tablet with levonorgestrel, a hormone that has been used in many birth control pills for several decades. Plan B One-Step® contains a higher dose of levonorgestrel than birth control pills, but works in a similar way to prevent pregnancy. It works mainly by stopping the release of an egg from the ovary. It is possible that Plan B One-Step® may also work by preventing fertilization of an egg (the uniting of sperm with the egg) or by preventing attachment (implantation) to the uterus (womb).
You have 72 hours (3 days) to try to prevent pregnancy after birth control failure or unprotected sex. The sooner you take Plan B One-Step®, the better it works.
If Plan B One-Step® is taken as directed, it can significantly decrease the chance that you will get pregnant. About 7 out of every 8 women who would have gotten pregnant will not become pregnant.
You will know Plan B One-Step® has been effective when you get your next period, which should come at the expected time, or within a week of the expected time. If your period is delayed beyond 1 week, it is possible you may be pregnant. You should get a pregnancy test and follow up with your healthcare professional.
If you have questions or need more information, call our toll-free number, 1-800-330-1271, or visit our website at www.PlanBOneStep.com.

rtc-captureconfig
This is a simple parser that takes a string of text and determines what that means in the context of WebRTC.
Why?
It provides a simple, textual way of describing your requirements for media capture. Trying to remember the structure of the constraints object is painful.
How
A simple text string is converted to an intermediate JS object
representation, which can then be converted to a getUserMedia constraints
data structure using a toConstraints()
call.
For example, the following text input:
camera min:1280x720 max:1280x720 min:15fps max:25fps
Is converted into an intermedia representation (via the CaptureConfig
utility class) that looks like the following:
{
camera: 0,
microphone: 0,
res: {
min: { w: 1280, h: 720 },
max: { w: 1280, h: 720 }
},
fps: {
min: 15,
max: 25
}
}
Which in turn is converted into the following media constraints for a getUserMedia call:
{
audio: true,
video: {
mandatory: {},
optional: [
{ minFrameRate: 15 },
{ maxFrameRate: 25 },
{ frameRate: { min: 15, max: 25 } },
{ minWidth: 1280 },
{ maxWidth: 1280 },
{ width: 1280 },
{ minHeight: 720 },
{ maxHeight: 720 },
{ height: 720 }
]
}
}
Experimental: Targeted Device Capture
While the rtc-captureconfig
module itself doesn't contain any media
identification logic, it is able to the sources information from a
MediaStreamTrack.getSources
call to generate device targeted constraints.
For instance, the following example demonstrates how we can request
camera:1
(the 2nd video device on our local machine) when we are making
a getUserMedia call:
// load in capture config
var capture = require('rtc-captureconfig');
// pull in the getusermedia helper module
// see: https://github.com/HenrikJoreteg/getUserMedia
var getUserMedia = require('getusermedia');
// get the sources
MediaStreamTrack.getSources(function(sources) {
var constraints = capture('camera:1').toConstraints({ sources: sources });
/* here is an example of what the generated constraints actually look like
var constraints = {
audio:true,
video: {
mandatory: {},
optional: [
{ sourceId: '30a3f6408175c22df739bcbf9573d841d9f99289' }
]
}
};
*/
// get user media
getUserMedia(constraints, function(err, stream) {
if (err) {
return console.log('Could not capture stream: ', err);
}
console.log('captured stream: ', stream);
});
});
It's worth noting that if the requested device does not exist on the
machine (in the case above, if your machine only has a single webcam - as
is common) then no device selection constraints will be generated (i.e.
the standard { video: true, audio: true }
constraints will be returned
from the toConstraints
call).
Experimental: Screen Capture
If you are working with chrome and serving content of a HTTPS connection, then you will be able to experiment with experimental getUserMedia screen capture.
In the simplest case, screen capture can be invoked by using the capture string of:
screen
Which generates the following contraints:
{
audio: false,
video: {
mandatory: {
chromeMediaSource: 'screen'
},
optional: []
}
}
Reference
CaptureConfig
This is a utility class that is used to update capture configuration details and is able to generate suitable getUserMedia constraints based on the configuration.
camera(index)
Update the camera configuration to the specified index
microphone(index)
Update the microphone configuration to the specified index
screen(target)
Specify that we would like to capture the screen
max(data)
Update a maximum constraint. If an fps constraint this will be directed
to the maxfps
modifier.
maxfps(data)
Update the maximum fps
min(data)
Update a minimum constraint. This can be either related to resolution or FPS.
minfps(data)
Update the minimum fps
toConstraints(opts?)
Convert the internal configuration object to a valid media constraints
representation. In compatible browsers a list of media sources can
be passed through in the opts.sources
to create contraints that will
target a specific device when captured.
var media = require('rtc-media');
var capture = require('rtc-captureconfig');
// get the sources
MediaStreamTrack.getSources(function(sources) {
// get the cameras
var cameras = sources.filter(function(info) {
return info && info.kind === 'video';
});
// create videos
var videos = cameras.map(function(info, idx) {
return media(capture('camera:' + idx).toConstraints({ sources: sources }));
});
// render the videos
videos.forEach(function(vid) {
vid.render(document.body);
});
});
"Internal" methods
_parseRes(data)
Parse a resolution specifier (e.g. 1280x720) into a simple JS object (e.g. { w: 1280, h: 720 })

The Subject is the world's smallest escape room.
Taking classic escape room gameplay, compressing it down to an uncomfortably small scale and mixing in a mind-bending narrative, The Subject is a truly unique experience for two or more players.
Description
The Subject is an escape room experience like no other. The game is designed for multiple players; one player enters a small, cramped box, and is locked inside. The other player(s) must solve a series of puzzles to free their teammate. The twist? The information they need to solve the puzzles is on the inside of the box. In the ultimate test of communication, concentration and calmness under pressure, players must work together to piece together a mysterious narrative, solve the puzzles, and free the subject from the box before their time is up... The goal of the project is twofold: redefine what escape room games can be, and take them to a new level of intensity.
FAQs
Q. How long does the experience take to play?
A. Players have a maximum time of 30 minutes to complete the game.
Q. But what's the quickest a team has completed it?
A. Just over 19 minutes.
Q. Exactly how big is the box?
The box is roughly 120cm long, 50cm wide and 70cm deep.
Q. More importantly, is the box safe?
Of course. The box was built with player safety in mind, and there are a number of safety procedures in place to ensure that any risks are mitigated.
The box is well ventilated, and a light is provided as part of the experience. The player is able to communicate with those outside throughout the game. A gamemaster is always overseeing the experience whilst a player is inside the box, and they can signal to the gamemaster if they want to get out before the game is over.
The box, whilst secure, is easy to dismantle in the event of a medical emergency. The use of pin hinge fasteners allow the box to be completely taken apart in seconds.
A full and detailed risk assessment is available on request.
Whilst the box is safe, participants who suffer from claustrophobia are advised to avoid entering the box as part of the experience.
Events and Coverage
An early build of The Subject received a preview showing at Newspeak House in July 2019. The project debuted as part of the Experiments in Play exhibition at Goldsmiths, University of London, in September 2019. Previous press coverage includes Metro and LadBible.

Ashok Chavan accuses BJP of poaching attempts
by Mrityunjay BoseIndicating attempts of poaching by the BJP, senior Congress leader and former chief minister Ashok Chavan said that the saffron party has booked hotels where rival parties' MLAs are staying.
"The BJP is trying to buy time, the motive is to poach MLAs from other parties," Chavan said, adding that "BJP people" are booking rooms in hotels were the MLAs of other parties are lodged.
Chavan was speaking outside the J W Marriot in Juhu, where the Congress MLAs have been lodged.
Two intelligence officers apprehended
Meanwhile, in a dramatic development, a group of NCP leaders "apprehended" a couple of officers of the local Intelligence unit, when they were seen inside the Renaissance hotel at Powai.
"You are a senior officer, what is the purpose of coming here," NCP MLA Dr. Jitendra Awhad was seen asking them.
At least, two plainclothesmen were apprehended and their identity cards were checked. One of the policemen told the NCP leaders that they were on duty inside the hotel.
