nutanix
Businessmodel of Nutanix
Customer Segments
Nutanix has a mass market business model, with no significant differentiation between customer groups. The company targets its offerings at organizations of all industries and sizes.
Value Proposition
Nutanix offers four primary value propositions: convenience, innovation, performance, and brand/status.
The company offers convenience by making life easier for clients. It simplifies datacenter infrastructure by integrating storage and server resources into a turnkey appliance that can be deployed in just 30 - 60 minutes. It also scales storage quickly, going from three servers to thousands.
The company has embraced innovation as a part of its culture. Its Enterprise Cloud Platform leverages hyperconvergence and Intel x86-based servers to natively integrate storage, compute, and virtualization in scale-out clusters. It replaces the need for separate management processes.
The company demonstrates strong performance through tangible results. It claims to have an 8x faster time-to-value in buying, implementing, and managing than any other hyperconvergence solution. Also, research firm IDC projected in 2015 that on average, organizations’ use of IT solutions powered by Nutanix software would yield five-year discounted benefits worth $7.85 million, a return on investment of 510%, a payback period of 7.5 months, and a reduction in their total cost of ownership by 58.3% over five years. Specific examples of positive outcomes for clients include:
- Insurance firm ADD used Nutanix’s solutions to speed up the installation of a virtual desktop infrastructure, reducing the time taken from three months to 14 days
- Agilis Networks used Nutanix’s solutions to implement a new storage solution, resulting in savings of $12,000 in power and electricity costs over 3 years
- Akron Public Schools used Nutanix’s solutios to replace its infrastructure, resulting in savings of over 20 hours of compute time per week
- ASL Airlines France used Nutanix’s solutions to install new infrastructure, resulting in a reduction in the time taken for computer systems to connect to sessions, from three minutes to 20 seconds The company reduces costs by offering flexibility. It operates the Nutanix GSOFlex Services Credit program, which enables clients to earn credits when they purchase its products. These credits can be used to purchase consulting, training, and other services in the future. The program includes packaged services that provide built-in volume discounts.
The company has established a strong brand due to its success. IDC indicates that it generated 52% of all hyperconverged revenue worldwide during the first half of 2014. It has a Net Promoter Score of 92 and a 9.6 Customer Satisfaction Rating, one of the highest customer satisfaction scores in the hyperconvergence industry. It has over 4,400 customers in over 90 countries. It claims its clients include the #1 companies in the drug, home retail, media, medical, auto, beverage, and electronics industries.

Besides that, these are the recommended steps to follow when videos are not received:
- Access your OpenVidu dashboard (
https://YOUR_OPENVIDU_IP:4443
) to quickly test the video transmission (user: OPENVIDUAPP, pass: [your private secret]) - Please be sure that your OpenVidu Server host meets the network requirements.
The other 1% of the time this can be an attempt of accessing the same camera from two different browsers at the same time. Remember that Chrome, Firefox, Opera and Safari are distinct processes which cannot generally access the same physical resource (as a webcam) at the same time on your computer. On the other hand, accessing the camera from different tabs of the same browser is tipically possible.
2. Any tips to make easier the development of my app with OpenVidu?
You can do some things to improve your efficiency while using OpenVidu:
Multiple tabs to test the video transmission
You can use multiple tabs in the same browser to test your video streams.
WARNING: you may have trouble for testing with tabs from different browsers at the same time, as they compete for the camera access.
Be very aware of the browser's console
There you can find logs reporting important stuff. Error messages can help you to solve many issues.
OpenVidu Browser is developed with both Chrome (first image) and Firefox (second image) in mind in terms of logging. By default the browser's console displays OpenVidu's high-level messages (that's when the option 'Info' is enabled, as seen in the images). This means logs about OpenVidu objects being created and destroyed and logs for each triggered event (only for those you are subscribed to).
Warn and Error messages are specifically reserved for unwanted situations, and you should check your code in case you spot one of them.
If you enable the lowest level of logging you can see all the messages concerning the WebRTC negotiation process (generally not very interesting for an OpenVidu user).
Remember the browser's cache
If you have changed your HTML, JavaScript or CSS code, refreshed the page and cannot see the changes on the browser, probably the cache is still serving the old files. To perform a hard reload of your page on the browser, press Ctrl + Shift + R
Use Ngrok to share your app
Do you want to be able to publish your development app over your network or even the Internet, without really having to deploy it in a server? This can be very helpful, as you can test with different devices and browsers at the same time. To achieve this, you can use Ngrok. The set up for Ubuntu is quite simple:
- Download Ngrok with this link [LINK] and unzip it.
- Download this Ngrok configuration file (named
ngrok.yml
) from our GitHub repo [LINK] and place it in the same path as Ngrok binary. - Run Ngrok with this command:
./ngrok start --all -config=ngrok.yml
. You will get two public IPs (ended with.ngrok.io
) publishing your local addresslocalhost:5000
andlocalhost:3000
. - You just have to run you app at port
3000
and run OpenVidu Server locally adding this parameter:- When running OpenVidu Server as a Docker container:
-e spring.profiles.active=ngrok
- When running OpenVidu Server as a JAR:
-Dspring.profiles.active=ngrok
- When running OpenVidu Server as a Docker container:
- That's it! Now you can connect to your app through the Ngrok public IP and the connection to OpenVidu Server will work just fine. You have "deployed" your app on your own computer, and cross-device testing through your own network is now possible. Connecting to your app over the Internet is also possible, but the video transmission may not work (check this FAQ to learn why).
3. I am using Windows to run the tutorials / develop my app. Anything I should know?
Yes, some little changes are needed because of the way Docker runs on Windows. In Linux/Mac, Docker containers are easily accesible through localhost
, but in Windows you will have to use the specific IP allocated to your container (usually <IP_ADDRESS>
).
First of all, you must launch the developing Docker container of OpenVidu Server (openvidu/openvidu-server-kms) setting paramater openvidu.publicurl
to the IP allocated for Docker in your Windows machine.
What in Linux/Mac is...
docker run -p 4443:4443 --rm -e openvidu.secret=MY_SECRET openvidu/openvidu-server-kms:2.7.0
...in Windows is...
docker run -p 4443:4443 --rm -e openvidu.secret=MY_SECRET -e openvidu.publicurl=https://<IP_ADDRESS>:4443/ openvidu/openvidu-server-kms:2.7.0
Then, to let your applications know how to connect to OpenVidu Server:
Applications Client-Side Only
(Tutorials openvidu-hello-world, openvidu-insecure-js, openvidu-insecure-angular, openvidu-getaroom)
When consuming openvidu-server REST api, change location.hostname
to the IP of the Docker container running openvidu-server (usually <IP_ADDRESS>
). For every one of the insecure tutorials listed above, the url where to send the REST operations ...
"https://" + location.hostname + ":4443/api/<OPERATION>"
... in Windows is ...
"https://<IP_ADDRESS>:4443/api/<OPERATION>"
Change this url in every insecure tutorial right here:
- openvidu-hello-world: here
- openvidu-insecure-js: here
- openvidu-insecure-angular: here
- openvidu-getaroom: here
Also you will need to serve your apps over https. Browsers only accept camera usage on http when the address is localhost, and here it will be
<IP_ADDRESS>
or the one that Docker picks up for you. To serve over https withhttp-server
, generate a self-signed certificate and run with-S
flag on the root path of your app:Generate a selfsigned certificate (run in your Docker console)
openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -subj '//CN=www.mydom.com\O=My Company LTD.\C=US' -keyout key.pem -out cert.pem
Run with SSL flag
http-server -S
Applications Client-Side + Server-Side
(Tutorials openvidu-js-java, openvidu-mvc-java, openvidu-js-node, openvidu-mvc-node)
You must let know your app/tutorial how to initialize openvidu-java-client or openvidu-node-client (or where to send your REST API operations in case you are not using any of these clients). For example:
-
Java tutorials (tutorials openvidu-js-java, openvidu-mvc-java): override the default value of the property
openvidu.url
:mvn package exec:java
in Windows is...
mvn -Dopenvidu.url=https://<IP_ADDRESS>:4443/ package exec:java
With this change we are simply changing the param
urlOpenViduServer
that our OpenVidu object from openvidu-java-client will receive in its constructor. This change is something related to these specific applications. -
Node tutorials (tutorials openvidu-js-node, openvidu-mvc-node): change the URL param passed on launch:
node server.js https://localhost:4443/ MY_SECRET
in Windows is...
node server.js https://<IP_ADDRESS>:4443/ MY_SECRET
With this change we are simply changing the param
urlOpenViduServer
that our OpenVidu object from openvidu-node-client will receive in its constructor. This change is something related to these specific applications.
4. Does my app need a server-side?
First of all, let's differentiate between OpenVidu server-side and your application's server-side.
- You will always need OpenVidu Server deployed at some place on the Internet (check the Deployment section to learn how to do it in 5 minutes). For now, OpenVidu doesn't support p2p direct connections between two users, so all the traffic must flow to OpenVidu Server or from OpenVidu Server.
- You will generally want your application to have its own server-side. Why?
Well, it is really not necessary. You can have a pure client-side application if you want. Just check any of these tutorials:
openvidu-hello-world, openvidu-insecure-js, openvidu-getaroom
The problem here is pretty evident: if you don't have any kind of server side to control your users, anyone can use your app. In fact, you can respectively see here, here and here a comment warning about this matter in every insecure tutorial. Due to the lack of a server-side in these tutorials, we have no choice but to embed the REST API consumption methods in our JavaScript code, which includes hardcoding our secret in the JS client code.
IMPORTANT: Do NOT include your SECRET in your JavaScript or HTML files in a production environment!
First an OpenVidu app Client-Side Only.
Second an OpenVidu app Client-Side + Server-Side.
In production you will usually want the second option to avoid unwanted users.
5. The CloudFormation Stack is a nice option for Amazon, but I don't like it. I want more control
You can always deploy everything by yourself. To do so, check Deploying OpenVidu on Ubuntu section.
6. What are STUN and TURN servers and why do I need them?
If the user's devices don't have a public and reachable IP, WebRTC connections cannot be established and therefore, video streams cannot be sent or received. This occurs when the users are behind NAT's and Firewalls. In brief, when they are hidden under complex networks.
In order to support these circumstances, WebRTC relies on STUN and TURN servers:
- STUN can easily provide to the user's devices their own public IP (the IP that other devices on the Internet use to connect to it), so they can tell OpenVidu where to send the video streams. Only with a STUN server, around 86% of the time the connection will be successful.
- TURN is an extension of STUN, and covers the most extreme cases of complex networks (symmetric NATs). It acts as a gateway, passing all the media streams form one side to the other. This situation will occur with a probability of around 8%.
For all purposes, OpenVidu Server acts as a final user, and your connections may fail if it is hosted behind a complex network. To provide a a solid service you definitely need both STUN and TURN servers. There are many public, free-to-use STUN servers (STUN server list), but because TURN always faces a much larger load when coming into play, no one offers it free of charge. The good news is that it is very easy to install a COTURN server, which offers both STUN and TURN:
- Our ready-to-use CloudFormation stack already includes a properly configured COTURN server.
-
If you are deploying OpenVidu Server by your own, there are detailed instructions in the Deploying OpenVidu as a native service section, which explains how to install, configure and run COTURN on Ubuntu.
You can test your COTURN server on this website: Trickle ICE. To do so, remove the default Google server from the list and add your own following this format:
turn:YOUR_TURN_IP:YOUR_TURN_PORT
(add your TURN username and password below)
7. What does OpenVidu not integrate regarding WebRTC and Kurento yet?
As the main goal OpenVidu has is to make as simple as possible the integration of video-call capabilities in applications, it would make little sense to support all the features provided by Kurento: why would most of developers want visual recognition or augmented reality capabilities when adding video-calls to their apps?
But there's also a bunch of features supported by Kurento or WebRTC that will be part of OpenVidu as well:
- Video composing: right now OpenVidu streams are always sent and received without any processing in Kurento Media Server, so every subscription to a video stream in a video-session implies its own WebRTC connection. We intend to provide the possibility of configuring video-sessions to be processed and send as only one video, composed in a grid by all the published streams.
- Direct p2p connections between users: OpenVidu will offer the possibility of connecting users without having to use Kurento Media Server as central node. This can be very advantegeous for certain use-cases, as will reduce the need of infraestructure.
- Single stream video recording: OpenVidu will support single stream recording, not only composed recording.
8. Does OpenVidu support Android and iOS?
Since release 2.7.0 Android and iOS are supported through Ionic. You can try openvidu-ionic tutorial and you will have an OpenVidu native application compatible with both Android ang iOS working in minutes.
In the future OpenVidu team plans to support React Native and Native Script frameworks in the same manner.
9. Which is the current status of OpenVidu on scalability and fault tolerance?
OpenVidu load testing process is described in detail in this Medium post. Results are the following for 7-to-7 sessions were every participant sends one audio-video stream (540x360, 30 fps) and receives 6 remote streams (same video):
That said, one of the most important features OpenVidu will offer is the possibility of automated scalability and fault tolerance. We intend to provide an easy-to-use service integrated with Amazon Web Services to allow the automated launching and shutdown of servers depending on the workload of your application.
10. I am getting an "Error accessing the camera" and I have already granted permissions on the browser
If you are using Chrome: you cannot access the camera or microphone from a http
URL if it is not localhost
or <IP_ADDRESS>
. In a nutshell: in Chrome accessing the webcam on http://localhost:8080
or http://<IP_ADDRESS>:8080
is perfectly OK. But, for example, on http://<IP_ADDRESS>:8080
it will through an error saying "Only secure origins are allowed". If for any reason you want to serve your app locally on a custom URL, the only solution is to serve it over https
with a certificate. If you are making use of the web server we have strongly suggested over the documentation (npm install -g http-server
), you can do this with the following commands on your application's root path:
-
Generate a selfsigned certificate with openssl
openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -subj '/CN=www.mydom.com/O=My Company LTD./C=US' -keyout key.pem -out cert.pem
-
Run http-server with SSL flag
http-server -S
11. My Safari users with role SUBSCRIBER
are not able to receive any remote video
Safari needs a user gesture to allow videos to automatically start playing if they have audio. This applies to users with role SUBSCRIBER
: that is, users that don't need to perform a call to OpenVidu.initPublisher. If a user access its camera or microphone, then there's no need of user gestures at all (as soon as they accept camera permissions, remote videos will automatically start playing).
So, in this particular case developers must show a button their SUBSCRIBER users must click (any other action that counts as user-gesture is also suitable), and the action executed upon click event should include a call to video.play()
. The actual video element is completely irrelevant. It can be hidden and with no media attached at all. For example:
<!-- This can be placed anywhere in the DOM. For example, as last child of <body> element -->
<video id="hidden-video"></video>
// Javascript code run upon any user gesture
var video = document.getElementById("hidden-video").play();
After this JavaScript line has been executed any remote video will start playing. This process is not necessary for future subscribed videos, when there is already some audio being played in the DOM.


It wraps the official (but undocumented?) feed, simply duplicating the image links into inline images. The results are cached.
Enhancing feeds by wrapping them is really easy if you know your way around regular expressions. XML parsing would probably be overkill. Caching the feed is a courtesy to the source provider, and doesn’t add a lot of code.
This is the code for this feed:

The assay of light water reactor (LWR) fuel using the LWR collar detector is performed as described in Ref. 31. The calibration equation is
where m235 is the 235U mass per unit length of fuel, a and b are calibration parameters, and Dc is the corrected doubles rate:
where D is the measured doubles rate and where the ki are correction factors described below. In this section all rates are corrected for deadtime and background. The calibration equation is solved for m235 as shown in the section “Conventional Calibration Curve Assay.”
The six correction factors are:
k0 americium-lithium (AmLi) source yield factor
k1 efficiency factor
k2 detector response factor
k3 poison factor
k4 uranium factor
k5 miscellaneous effects factor
The source yield factor is
where
∆t1 = assay measurement date - calibration date
T1/2 = 241Am half life (433.6 years)
where
Y = neutron yield of the AmLi source used for the measurement (applied source)
YMRC95 = neutron yield of the reference AmLi source MCR95
The relative yields ry for a number of sources are listed in Table II of Ref. 31.
The standard deviation of k0 is
where
the singles rates measured for the reference and applied AmLi sources are estimated to have standard deviations of 0.3%.
The efficiency factor is
where Smeas is the measured singles rate for the applied AmLi source in the detector on the normalization measurement date and where the Sexp is the expected singles rate for the applied source:
where
= normalization measurement date – AmLi source MRC95 reference date
SMRC95 = singles rate for MRC95 in the detector on the MRC95 reference date
The standard deviation of k1 is
where
and is obtained from the normalization measurement; the measurement of MRC95 used to obtain the relative source yield is not the same measurement used to obtain the reference MRC95 singles rate for normalization measurements.
If
where pcollar is the acceptance limit for the collar normalization measurement in percent, then
The detector response factor k2 is
where
Dref_collar = doubles rate for the reference collar on the cross calibration date with the
reference fuel assembly.
and
Dapplied_collar = doubles rate for the applied collar on the cross calibration date with the
reference fuel assembly.
The standard deviation of k2 is estimated to be
The detector response factors for a number of collars are listed for BWR and PWR assemblies with and without cadmium liners in Tables XII-XV in Ref. 31.
The poison factor is
where
npoison = number of poison rods in the assay fuel assembly
Nref = total number of rods in the reference fuel assembly
Nassay = total number of rods in the assay fuel assembly
Ac, Bc, Cc = calibration constants
λa = poison absorption factor (also a calibration constant)
G = weight percent gadolinium in the poison rods
Een = weight percent 235U enrichment of the fuel
The standard deviation of k3 is
where
The enrichment is calculated from
where mU235 and mU238 are the declared masses of 235U and 238U in the fuel, respectively.
Then
where
The poison absorption factor λa does not have an assigned error; the other errors in the poison correction factor are quantities entered with the calibration parameters or with assay item data.
The uranium factor is
where
mU = total uranium mass (g)
Lfuel = fuel length (cm)
Dc, Ec = calibration constants
The total uranium mass and standard deviation are calculated from
and
respectively.
The standard deviation of k4 is
where
The errors needed for the uranium correction factor error calculation are quantities entered with the calibration parameters or with assay item data.
The miscellaneous effects factor is
where is the factor for the i-th effect and Neffects is the number of effects.
The standard deviation of k5 is
The total collar correction factor is
For the calculation of the error of kcollar, the normalization measurement date is set equal to the assay date:
= assay measurement date – AmLi source MRC95 reference date
this simplifies database operations in the INCC code and has zero or negligible effect on the error in practical situations.
Let
Then
where
However, if
and
then
The standard deviation of kcollar is then
where
where
The standard deviation of the corrected doubles rate Dc is then
where is the standard deviation of the measured doubles rate.
The assay 235U mass per unit length of fuel and the standard deviation (m235 and ) are then obtained from Dc and as shown in the section “Conventional Calibration Curve Assay.”
The total assay 235U mass is calculated from
the standard deviation is calculated as
where the weak correlation between m235 and Lfuel through the uranium correction factor k4 is ignored as insignificant in practical situations.
Finally, the declared minus assay mass difference and standard deviation are
and
where the weak correlation between and through the poison correction factor k3 and the uranium correction factor k4 is ignored as insignificant in practical situations. Because the k3 and k4 correction factors are insensitive to the 235U mass, the assay solution for is not iterated.

Initialize this module.
This function is called from netif.c when address is changed or netif is removed
| old_addr | IP address of the netif before change |
| new_addr | IP address of the netif after change or NULL if netif has been removed |
| u32_t tcp_next_iss | ( | struct tcp_pcb * | pcb | ) |
Calculates a new initial sequence number for new connections.
| void tcp_pcb_purge | ( | struct tcp_pcb * | pcb | ) |
Purges a TCP PCB. Removes any buffered data and frees the buffer memory (pcb->ooseq, pcb->unsent and pcb->unacked are freed).
| pcb | tcp_pcb to purge. The pcb itself is not deallocated! |
Purges the PCB and removes it from a PCB list. Any delayed ACKs are sent first.
| pcblist | PCB list to purge. |
| pcb | tcp_pcb to purge. The pcb itself is NOT deallocated! |
Default receive callback that is called if the user didn't register a recv callback for the pcb.

CannotCompileException
public static CtMethod wrapped(CtClass returnType, java.lang.String mname, CtClass[] parameterTypes, CtClass[] exceptionTypes, CtMethod body, CtMethod.ConstParameter constParam, CtClass declaring) throws CannotCompileException
Object
.
The body of the created method is a copy of the body of the method
specified by body
. However, it is wrapped in
parameter-conversion code.
The method specified by body
must have this singature:
Object method(Object[] params, <type> cvalue)
The type of the cvalue
depends on
constParam
.
If constParam
is null
, the signature
must be:
Object method(Object[] params)
The method body copied from body
is wrapped in
parameter-conversion code, which converts parameters specified by
parameterTypes
into an array of Object
.
The returned value is also converted from the Object
type to the type specified by returnType
. Thus,
the resulting method body is as follows:
Object[] params = new Object[] { p0, p1, ... }; <type> cvalue = <constant-value>; ... copied method body ... Object result = <returned value> return (<returnType>)result;
The variables p0
, p2
, ... represent
formal parameters of the created method.
The value of cvalue
is specified by
constParam
.
If the type of a parameter or a returned value is a primitive
type, then the value is converted into a wrapper object such as
java.lang.Integer
. If the type of the returned value
is void
, the returned value is discarded.
Example:
ClassPool pool = ... ; CtClass vec = pool.makeClass("intVector"); vec.setSuperclass(pool.get("java.util.Vector")); CtMethod addMethod = pool.getMethod("Sample", "add0"); CtClass[] argTypes = { CtClass.intType }; CtMethod m = CtNewMethod.wrapped(CtClass.voidType, "add", argTypes, null, addMethod, null, vec); vec.addMethod(m);
where the class Sample
is as follows:
public class Sample extends java.util.Vector { public Object add0(Object[] args) { super.addElement(args[0]); return null; } }
This program produces a class intVector
:
public class intVector extends java.util.Vector { public void add(int p0) { Object[] args = new Object[] { p0 }; // begin of the copied body super.addElement(args[0]); Object result = null; // end } }
Note that the type of the parameter to add()
depends
only on the value of argTypes
passed to
CtNewMethod.wrapped()
. Thus, it is easy to
modify this program to produce a
StringVector
class, which is a vector containing
only String
objects, and other vector classes.
returnType
- the type of the returned value.mname
- the method name.parameterTypes
- a list of the parameter types.exceptionTypes
- a list of the exception types.body
- the method body
(must not be a static method).constParam
- the constant parameter
(maybe null
).declaring
- the class to which the created method is
added.

About Allen Brain Atlas-Driven Visualizations
Welcome to Allen Brain Atlas-Driven Visualizations (ABADV), a web-based application created for visualizing expression energy data from the Allen Brain Atlas (ABA).
ABADV combines the ABA Application Programming Interface (API), a resource enabling programmatic access to their dataset, with Data-Driven Documents (D3), a library that uses digital data to drive the creation and control of dynamic and interactive visualizations.Try ABADV!
ABADV accepts only gene symbols and brain structure acronyms as its input. Symbols used to query genes in the Allen Mouse Brain Atlas follow the same guidelines established by the International Committee on Standardized Genetic Nomenclature for Mice, which you can find at Mouse Genome Informatics. Acronyms used to query brain structures in the Allen Mouse Brain Atlas are based on the Allen Reference Atlas.
ABADV was developed for Google Chrome.
News & Updates
April 15th, 2014
Significant changes to ABADV, including: the ability to now filter results by probe (antisense, sense or both), section (coronal, sagittal or both), and visualization (pie, bar, heatmap or all three); collecting all available visualizations into a single page so users don't bounce around between separate pages; and minor bug fixes (erroneous input, garbeled text and visuals, performance, etc.)
March 11th, 2014
Submitted a Methods article that explains how ABADV works to Frontiers in Neuroinformatics. The article is pending publication, but an abstract is available.
Feburary 10th, 2014
ABADV is launched and publicly avaiable through GitHub. ABADV is licensed under the MIT License (MIT).

The world's finest radio station, Resonance104.4FM, is in urgent need of funding. You can help the station remain on air by sponsoring next week's Hooting Yard On The Air show, to be broadcast (live as ever) at 4.00 PM on Wednesday 14 February. Here is how it works:
1. Go to Resonance and donate a minimum of £5.
2. You may now choose a sentence, a phrase, a string of words, or a name to be incorporated into a specially-written story which will feature on next week's show.
3. Send your chosen words to me at<EMAIL_ADDRESS>and voila!, it's as simple as that.
4. After reading the story, I will recite the names of the donors (unless anonymity is preferred).
5. Now follow Step 1, immediately!

Headless Testing
One major use case of PhantomJS is headless testing of web applications. It is suitable for general command-line based testing, within a precommit hook, and as part of a continuous integration system.
Test Frameworks
PhantomJS itself is not a test framework, it is only used to launch the tests via a suitable test runner.
The following table summarizes the list of various test frameworks and the corresponding test runners. If the framework does not need an external/third-party runner, it is marked as "built-in".
| Framework | Test Runner |
|---|---|
| Buster.JS | built-in |
| Capybara | Poltergeist, Terminus |
| Mocha | Chutzpah, mocha-phantomjs |
| FuncUnit | built-in |
| Hiro | built-in |
| Karma (née Testacular) | built-in |
| Jasmine | Chutzpah, grunt-jasmine-runner, guard-jasmine, phantom-jasmine |

PhantomJS includes run-qunit and run-jasmine in its examples
subdirectory. However, these are for illustration purposes and lack important reporting features necessary for real-world uses!
PhantomJS tailored testing
In addition, there are Related Projects which are built on top of PhantomJS to provide convenient high-level functionality for testing purposes:
- Casper.js is useful to build scripted navigation and testing
- Lotte adds jQuery-like methods, chaining, and more assertion logic
- WebSpecter is a BDD-style acceptance test framework for web applications
Continuous Integration Systems
Using PhantomJS with CI system such as Jenkins or TeamCity does not require special setup. Make sure PhantomJS is installed properly on the slave/build agent and it is ready to go.
Since PhantomJS is purely headless on Linux, the agent can run on an installation with any GUI. This means, a barebone Linux system without X11 is not a problem for PhantomJS. It makes it possible to spawn light build agents on Amazon EC2 or Heroku instances.
Travis CI, a popular hosted CI system, has built-in support for PhantomJS. See its documentation for details.


This post goes over how to download and use Census and ACS data from within R using the tidycensus
and acs
packages. When possible I would suggest using the tidycensus
package as the functions are much easier to work with and provide a cleaner output. The tidycensus
package, unfortunately, does not cover the entirity of the census geographies and that is when we must use the acs
package. They both access the same data so reults should not differ if you decide to use one package over another.

library(stringr)

# api key needs to be your own ACS api key!
# you can get one here http://api.census.gov/data/key_signup.html
apiKey <- read_json("~/Documents/PopDataDemo/keys/acs.json")
## Error in open.connection(con, "rb"): cannot open the connection

View Variables for a particular Census/5 year ACS using tidycensus
Trying to figure out exactly what you want from the census data for any given year is probably the most tedious part of navigating the census and ACS data. There is a lot of information in there and the structure of it is not exactly intuitive. Lets say that you know that you want to look at the data from the 2014 five year ACS and you want to find household income data broken down by race. We can start by downloading the variable name sheet which has on the order of 10's of thousands of different variables and start navigating from there. I could search in the interactive table code below I can narrow my search results a bit by using “income race” in the search box, a working demo found here. For this demo I am going to use the B19013
median household income variables.
v14acs <- load_variables(2014, "acs5", cache=T)
## Search Interactively with this code
# v14acs %>%
# datatable (style="bootstrap")
v14acs %>%
filter(grepl("B19013", name)) %>%
as.data.frame %>%
head %>%
kable
| name | label | concept |
|---|---|---|
| B19013_001 | Estimate!!Median household income in the past 12 months (in 2014 Inflation-adjusted dollars) | MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2014 INFLATION-ADJUSTED DOLLARS) |
| B19013A_001 | Estimate!!Median household income in the past 12 months (in 2014 Inflation-adjusted dollars) | MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2014 INFLATION-ADJUSTED DOLLARS) (WHITE ALONE HOUSEHOLDER) |
| B19013B_001 | Estimate!!Median household income in the past 12 months (in 2014 Inflation-adjusted dollars) | MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2014 INFLATION-ADJUSTED DOLLARS) (BLACK OR AFRICAN AMERICAN ALONE HOUSEHOLDER) |
| B19013C_001 | Estimate!!Median household income in the past 12 months (in 2014 Inflation-adjusted dollars) | MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2014 INFLATION-ADJUSTED DOLLARS) (AMERICAN INDIAN AND ALASKA NATIVE ALONE HOUSEHOLDER) |
| B19013D_001 | Estimate!!Median household income in the past 12 months (in 2014 Inflation-adjusted dollars) | MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2014 INFLATION-ADJUSTED DOLLARS) (ASIAN ALONE HOUSEHOLDER) |
| B19013E_001 | Estimate!!Median household income in the past 12 months (in 2014 Inflation-adjusted dollars) | MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2014 INFLATION-ADJUSTED DOLLARS) (NATIVE HAWAIIAN AND OTHER PACIFIC ISLANDER ALONE HOUSEHOLDER) |
In order to get those values for the household income data we need to build a vector of variables that we want from the acs that follow the naming structure mentioned above. We create it below and when we make the call to the ACS api using get acs we can say that we want these values at the county level with the geometries so we can map the data.
# the variables that I want in my download
incomeVars <- paste0("B19013", c("", LETTERS[1:9]), "_001E")
# downolad data the capture output stuff isnt neccesary its just to get rid
# of the output
t <- capture.output(rawIncomeDF <- get_acs(
geography="county", # I want county level data
variables=incomeVars, # iwant the variables from this list
year=2014, # from the 2014 acs
geometry=TRUE, cache=T)) # I also want the geometry data for mapping later
## Error in get_acs(geography = "county", variables = incomeVars, year = 2014, : A Census API key is required. Obtain one at http://api.census.gov/data/key_signup.html, and then supply the key to the `census_api_key` function to use it throughout your tidycensus session.
hispanicSPDF <- rawIncomeDF %>% # take my sf structure
filter(variable == "B19013I_001") %>% # isolate hispanic income data
filter(endsWith(NAME, ", California")) %>% # only look at CA
st_zm %>% # remove the third dimension which is probably altitude

The tidy_census
package is great but it isnt comprehensive and sometimes we need to rely on the acs
package which basically provides an R interface to ACS api. This allows us to acces geographies such as school districts. Below is a demo of using the acs
package to pull some data and then we can plot the distribution of Hispanic Household Incomes by school district.
# make the unified and secondary geographies seperatly
schoolsCA <- list(
unified=geo.make(
state="CA",
school.district.unified="*"),
secondary=geo.make(
state="CA",
school.district.secondary="*")
)
# pull both data sets
schoolResults <- lapply(schoolsCA, function(x){
acs.fetch(
endyear=2014,
span=5,
geography=x,
variable=str_sub(incomeVars, 1, -2),
key=apiKey)
}
)
## Error in paste0("https://api.census.gov/data/", endyear, "/acs/", dataset, : object 'apiKey' not found
# clean and merge them
schoolIncomeDF <- bind_rows(
schoolResults$unified@estimate %>%
as.data.frame %>%
mutate(`School District`=row.names(.)),
schoolResults$secondary@estimate %>%
as.data.frame %>%
mutate(`School District`=row.names(.)))
## Error in eval(lhs, parent, parent): object 'schoolResults' not found
# pllot the log distribution
schoolIncomeDF %>%
ggplot(aes(x=B19013I_001)) +
geom_density() +
theme_classic() +
xlab("Income in Dollars") +
ylab("Density") +
ggtitle("Hispanic Household Income Across California School Districts")

Thanks for visiting. Originally hailing from Wisconsin, I've made The Bay my second home. I'm a trained writer and educator and have decided to meld those skills into a career in web development. You can visit my blog about my experiences, or check out my recent projects here.
A few thank you's are in order. Namely: Thank you RocketU, the 3 month development program I finished at the end of 2014. Thank you Zed Shaw, whose learning materials and endless advice have helped me down this circuitous path. And thank you to everyone on places like StackOverflow and Reddit, who take tremendous amounts of time and care to collaborate, explain, and teach what they've learned. I'm continually amazed at the spirit of teamwork and camaraderie that is a bedrock of the coding community.
Looking through the lens of web development and technology, the future is truly, intoxicatingly exciting. I'm happy to be able to be a part of it and can't wait for what's next!
RocketU gave me a strong grounding in Python and Django, Javascript, jQuery, AngularJS, AJAX, PostgresSQL, testing, and deployment.
For me, from a creative background, data visualization was also something that really grabbed my attention. Moving forward, I'm working towards levelling up in my current skills, and expanding my skills with data, from statistical analysis to such staples as D3, Hadoop, and Apache Storm.
