I could be wrong about this, but I just had a quick glance at the
implementation and its seems to allocate datastructures of a size
proportial to the width of the domain. So if you have small values and
very large values, the width is going to be very large.
If I am right, then you might be better off encoding your N values into
the interval [0,N-1] and then possibly using an element constraint to
decode them where necessary.
Then again, I could be completely off base :-/
Cheers,

Enumerables as a class are an incredibly powerful tool to use when dealing with data structures, particularly for hashes and arrays. Enumerables are a sort of superclass, providing these extra methods for searching through and sorting these arrays and hashes.
As an example, one of the methods available for enumerables is the cycle
method. This method runs through every element of the given data structure, and executes a block of code on each of these elements. This will repeat either infinitely, or for a given number of iterations. To do this otherwise, without using an enumerables, you'd have to nest loops in messy logic and multiple iterators to accomplish the same thing.
example = ["hip","hip","hooray"]
example.cycle {|element| puts element} # hip hip hooray hip hip hooray hip hip hooray hip hip hooray ... (repeated infintely)
example.cycle(3) {|element puts element} # hip hip hooray hip hip hooray hip hip hooray
As the above code suggests, the original array isn't changed at all by the block of code, allowing it to be run repeatedly. A more complicated use of this could use cycle
to populate an empty hash with the same set of filler values and keys, to be replaced later. Or it could be used to return the same countdown from 10 constantly, and have it reset to 10 upon reaching 0.


These priors allow the user to bias the search for motifs by MEME. They give a position-specific prior distribution on the location of motif sites in sequence(s) in the input dataset.
The MEME Position Specific Priors (PSP) format includes the name of the sequence for which a prior distribution corresponds. Sequences not named in the PSP file are given uniform prior distributions on site locations by MEME.
A PSP must be created for a specific width of motif. This width must be specified for each entry in the PSP file, and must be the same for all entries. If MEME varies the motif width during computation, MEME renormalizes the PSP for each sequence. For motif widths larger than that of the prior, the renormalized prior of a site is the geometric mean of the original priors of all sites that it completely contains, normalized to sum to Pr(site). For motif widths smaller than that of the prior, the renormalized prior of a site is just the original prior, normalized to sum to Pr(>0 sites). MEME computes Pr(>0 sites) for a sequence is as the sum of the priors of all potential sites in the sequence and is 1 for the OOPS model, and ≤ 1 for the ZOOPS model.
MEME PSP format is similar to FASTA format. Each entry should start with a header line consisting of a sequence name (ID) followed by the width (WIDTH) of the PSP prior. The sequence name must match the name of a sequence in the FASTA file input to MEME. Any other text on the header line after the name and width is ignored by MEME.
The following lines (PRIORS) contain one number for each position in
the identically-named FASTA sequence, where the number gives the prior
probability of a motif site at that position in the sequence (or in the
reverse complement if -revcomp is specified).
All numbers for a PRIORS entry must be in the range (0,1] except
for the last w - 1
numbers, which should be 0 (shown in
blue in the example), since a motif of that width cannot start in those
positions. The numbers in a PRIORS entry must sum to a number no greater than 1.
If they sum to less than 1 and MEME is run with the -mod oops
switch,
MEME will rescale the numbers so that they sum to 1. With the -mod zoops>
switch, MEME does not rescale the numbers to sum to 1; a very small sum represents
a prior belief that the sequence contains no motif sites. The -mod anr
switch to MEME currently does not allow PSPs.
The format of an entry in a PSP file is:
>ID WIDTH PRIORS
An example of the PSP format is given below:
>ICYA_MANSE 4 0.075922 0.070764 0.082380 0.030292 0.025101 0.043139 0.032963 0.086047 0.057445 0.000000 0.000000 0.000000 >LACB_BOVIN 4 0.107099 0.099822 0.116208 0.042731 0.035408 0.060854 0.046499 0.000000 0.000000 0.000000
The psp-gen tool can be used to generate position-specific priors when supplied with two datasets of sequences: "primary" and "control".
Custom priors can also be built by hand, to, for example, favor including certain protein letters in motifs. To maximize their effect when used with MEME, a few points should be kept in mind:


Distributed systems
6. Communication
Importance of communication
- Interprocess communication is an esential part of all distributed systems
- Exchange of information is based on low-level message passing
- What kind of exchange is used for nondistributed platforms?
- Communication must adhere to specific rules
- communication protocol - a set of rules according to which
communication is carried out
- protocol is said to provide communication services
- two types of communication services:
- connection-oriented service - connection is
established bofore exchanging messages and specific parameters
of the used protocol , after exchange connection is terminated
- connectionless service - no setup in advance is needed
- protocols are easily explained if structured into layers
OSI reference model
- ISO OSI model (Open Systems Interconnection Reference Model)
- OSI is only refernce model and protocols developed
for OSI model have never been widely used
- however OSI model is useful for understanding computer networks
- application layer - e-mail protocols,
web access protocols, file transfer protocols
- presentation layer - how data are represented
independently of the hosts on which applications are running
- session layer - support for sessions
between applications,synchronization facilities.
Inserting checkpoints, which is useful in case of crash
- transport layer - protocols for directly
supporting applications (reliable communications, support of real
time streaming of data). Messages received from the upper
level are broken into smaller pieces suitable for the
transmission. How many packets are received, which have to be
retransmitted. TCP , UDP, ...
- network layer - protocols for
routing a message through a computer network and
handling congestions, IP (Internet protocol) is the most
widely used network protocol
- data link layer - detecting and possibly
correcting transmission errors, computing checksum
and adding it to the frame
- physical layer - concerned about
transmitting 0s and 1s. How many bits per second can be sent. Meaning
and number of pins in network connectors, etc...
standard network model used for internet which has fewer
rigidly defined layers then OSI, easier fit for
real-world protocols
- application layer - layer in which high level
protocols operate such as e-mail protocols,
web access protocols, file transfer protocols (HTTP,
HTTPS, FTP, IMAP, POP, SSH, SMTP, Telnet,...)
- transport layer - provides a channel for the
communicaton needs of applications
(TCP , UDP, DCCP, ...)
- internet layer - provides uniform networking
interface for exchanging datagrams, protocols for
routing a message through a computer network.
IP (Internet protocol) is the primary protocol in this
scope (IPv4, IPv6, ICMP, ...)
- link layer - includes protocols used to
describe local network topology and corresponds to
corresponds to the physical and data link layers of OSI model
MAC (Ethernet, Wi-Fi, DSL, ISDN, FDDI),...
Middleware protocols
- Middleware should be mostly applications which are mostly in the
application layer
- general purpose protocols offered for other applications
- DNS Domain Name System - distributed service used
to lookup a network addresses associated with a name
- translates more readable domain names to IP addresses
- for instance www.dhbw.de - > <IP_ADDRESS>
you can try ping dhbw.de
- Example Google Public DNS offered to internet users
worldwide - IP addresses <IP_ADDRESS> and <IP_ADDRESS> are used
for IPv4 service,
- authentication and authorization protols could be
example of middleware protocols
UDP (User Datagram Protocol)
- UDP is a simple transport protocol which extends host-to-host
delivery of packets
- connectionless protocol which belongs
to the transport layer
- abstract port numbers used to identify which processes communicate
- port numbers hold for a single host
- that's why pair port, host-ip is used for demultiplexing in UDP
- unreliable, unordered delivery
TCP protocol
- TCP is a connection-oriented protocol which belongs
to the transport layer
- connection is maintained from the beginning till
the end of exchange
- handshaking - exchange of control messages -
sender, receiver state before data exchange
- to agree to establish connection
- to agree on connection parameters
- full duplex data- bi directional data flow
in same connection
TCP dataram
Socket programming
- many distributed systems built on top of the simple
message-oriented model offered by the transport layer
- socket is conceptually a communication end
point
- to which an application can write data to be sent over
an underlying network
- from which incoming data can be read
- socket is a specialized software used for communication between
a client and a server
- one socket is located on the server side and one on the client side
- socket makes an abstraction over the actual port that is used
by the local operating system for a specific transport protocol
Socket operations for TCP/IP
| Operation |
Description |
| socket |
Create a new communication end point |
| bind |

pending connection requests should be |
| accept |
Block caller until a connection request arrives |
| connect |
Actively attempt to establish a connection |
| send |
Send some data over the connection |
| receive |

Connection-oriented communication using sockets
Java Sockets
- java.net library offers classes for communication over Internet
- classes Socket, and ServerSocket from java.net library use TCP to communicate
over network
- classes DatagramPacket, DatagramSocket, and MulticastSocket are used with UDP
- usage of ServerSocket on the server side
ServerSocket serverSocket = new ServerSocket(port);
ServerSocket throws IOException if I/O errors occur
ServerSocket instance calls accept method and blocks the call until
method receives request from the server when Socket instance
is created (which represents connection between client and server)
Socket clientSocket = serverSocket.accept();
Java TCP Sockets - server side
- we use BufferedReader to read text from the client
BufferedReader in = new BufferedReader(
new InputStreamReader(clientServer.getInputStream()));
and PrintWriter instance to reply to the client
PrintWriter pw = new PrintWriter(
clientServer.getOutputStream(), true);
Java TCP Sockets - Simple Echo server
- the following lines will complete simple echo server
String inputLine;
while ((inputLine = br.readLine())!= null){
System.out.println(inputLine);
pw.println(inputLine);
}
this piece of code reads from client and sends the same text back to the client
Java TCP Sockets - Simple Echo client
- first have to instantiate Socket to connect to the server and again we
use BufferedReader and PrintWriter to work with text
Socket clientSocket = new Socket( ipAddress, portNumber);
PrintWriter pw = new PrintWriter(
clientSocket.getOutputStream(), true);
BufferedReader bf = new BufferedReader(
new InputStreamReader( clientSocket.getInputStream()));
Java TCP Sockets - Simple Echo client cont.
- the following code implements communication with the server
System.out.println("Connected to server!...");
Scanner scanner = new Scanner(System.in);
while(true){
System.out.println("Enter text");
String inputLine = scanner.nextLine();
if(inputLine.equalsIgnoreCalse("quit")) break;
pw.println(inputLine);
System.out.println("Server responce is !");
System.out.println(bf.readLine());
}
Java TCP Sockets - server side
public class HelloServer {
public static void start(int port)){
serverSocket = new ServerSocket(port);
clientSocket = serverSocket.accept();
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
BufferedReader in = new BufferedReader(
new InputStreamReader(clientSocket.getInputStream()));
String hellogreeting = in.readLine();
if ("Hello server".equals(hellogreeting)) {
out.println("Hello Client");
}
else {
out.println("Unknown greeting");
}
}
}
Java TCP Sockets - client side
public class HalloClient {
public void contactServer(String ip, int port) {
clientSocket = new Socket(ip, port);
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);
BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
out.println("Hello server");
String resp = in.readLine();
System.out.println(resp);
}
TCP Socket example in Java documentation

KnockKnock game
- 3 classes:
- KnockKnockServer
- KnockKnockClient
- KnockKnockProtocol
Java UDP Sockets
- DatagramSocket class
- constructor DatagramSocket(int port) throws SocketException
- constructs datagram socket and binds it to the specified port on the local machine
- java.net.SocketException indicates that socket could not be opened or couldn't be
bind to the specified local port
Java UDP Sockets - Multicasting example
- Multicasting is the ability to have one device send a message
to more recepients
- Idea is to use single ip address to send messages to many users
- Multicasting is used in our example to send messages
to a group on a periodic basis
- example of a time server
- server will send a date and time every second
- identical message is sent to all members of the group
- server only broadcast messages,
it receives no messages from clients
- command Thread.sleep(1000)
is used to make a break of 1 second
- Why we use UDP and not TCP in this scenario?
Java UDP Sockets - Multicasting server
public class MulticastServer {
public static void main(String[] args) {
System.out.println("Multicast time server!");
DatagramSocket serverSocket = null;
try{
serverSocket = new DatagramSocket();
while(true){
String dateText = new Date().toString();
byte[] buffer = new byte[256];
dateText.getBytes();
InetAddress group = InetAddress.getByName("<IP_ADDRESS>");
DatagramPacket packet = new DatagramPacket(buffer, buffer.length,
group, 8888);
serverSocket.send(packet);
System.out.println("Time sent: " + dateText);
}catch(SocketException se){
se.printStackTrace();
}catch(IOException e){
e.printStackTrace();
}
}
Java UDP Sockets - Multicasting client
- MulticastSocket bound to the specified socket address
- to receive messages client must be joined to the group
- InetAddress is used to get the group
- in the for loop client receives 5 packets, prints their content
and after the loop leaves the group
Java UDP Sockets - Multicasting client cont.
public class MulticastClient {
public static void main(String args[]) {
System.out.println("Multicast Time Client");
try (MulticastSocket socket = new MulticastSocket(8888)) {
InetAddress group = InetAddress.getByName("<IP_ADDRESS>");
socket.joinGroup(group);
System.out.println("Multicast Group Joined");
byte[] buffer = new byte[256];
DatagramPacket packet = new DatagramPacket(buffer, buffer.length);
for (int i = 0; i < 5; i++) {
socket.receive(packet);
String received = new String(packet.getData());
System.out.println(received.trim());
}
socket.leaveGroup(group);
} catch (IOException ex) {
// Handle exception
}
System.out.println("Multicast Time Client Terminated");
}
}
HTTP - (HyperText Transfer Protocol)
- Probably the most widely used application layer protocol in the world today
- used to deliver resources across WWW
- delivered resources are mostly HTML HyperTextMarkupLanguage files,
but also audio, video, etc...
- users enter a URL address in a browser to obtain a resource
HTTP
- web browser has a role of client application and web server
has a role of server which responds to client requests
- default port used by servers is 80 (occasionally port 8080)
- famous http servers
- HTTP is stateless protocol - http server doesn't have to retain
information (status) of each user during multiple request
- secure transfer is possible using SSL (Secure Sockets Layer) -
extension known as HTTPS
- well known http servers:
- Apache HTTP server - the most used
- nginx
- Microsoft IIS
- Google Web server
- Appache Tomcat
- versions: HTTP 1.0, HTTP/1.1, HTTP/2
HTTP messages
- two types of messages: request and response
- request example
GET /path/file.html HTTP/1.1
Host: www.example.com
request methods specify desired action: GET, HEAD, POST, PUT,
DELETE, OPTIONS, TRACE, OPTIONS, CONNECT, PATCH
response header (example of an initial line)
HTTP/1.0 404 Not Found
response initial line contains response code which
reflects the status of the result
after the header and an empty line we have the actual content of the message
HTTP server response
HTTP/1.1 200 OK

Simple Web server implementation in Java
public class WebServer {
public WebServer() {
System.out.println("Web server started");
try (ServerSocket serverSocket = new ServerSocket(80)) {
while(true) {
System.out.println("Waiting for client request");
socket.receive(packet);
Socket remote = serverSocket.accept();
System.out.println("Connection made");
new Thread( new ClientHandler(remote)).start()
}
}catch (IOException ex) {
ex.printStackTrace();
}
}
public static void main(String args[]) {
new WebServer();
}
}
Web server - Client handler
public class ClientHandler implements Runnable {
private final Socket socket;
public ClientHandler(Socket socket) {
this.socket = socket;
}
@Override
public void run() {
System.out.println("\nClientHandler Started for " +
this.socket);
handleRequest(this.socket);
System.out.println("ClientHandler Terminated for "
+ this.socket + "\n");
}
}
Client which communicates with the Web server
- ClientHandler have to implement Runnable
because it is used in the thread constructor argument
public class ClientHandler {
public static Socket socket;
public static main(String[] args){
System.out.println("Web server started");
try (socket = new Socket(80)) {
while(true) {
System.out.println("Waiting for client request");
socket.receive(packet);
Socket remote = serverSocket.accept();
System.out.println("Connection made");
new Thread( new ClientHandler(remote)).start()
}
}catch (IOException ex) {
ex.printStackTrace();
}
}
}
RPC (Remote procedure calls)
- Client-server communication discussed so far is message-based
and we didn't conceal sending and receiving messages
- RPC is s way to achieve access transparency
- RPC provides a way to call a function on a remote server
using the same syntax as if you call it in the local library
- RPC is, for example, useful in the following situations:
- due to the size of the program there is a need
to spread it accross several machines
- there is a need to process information which is only available on a remote network
- when a process on machine A calls procedure(function) on B
it stops and wait while it's executed
- no message passing should be visible to the programmer
- remote procedure call should look as a local procedure call
RPC implementation
- implementation issues
- calling and called procedure run on different machines
and in different address space
- parameters and results also have to be passed
- RPC achieves transparency by offering client stub
to the calling client
- client stub has the same calling sequence as normal
procedure on the server side
- client stub doesn't execute operation but just sends
messages to the server
- server has a server stub (often referred
to as a skeleton) which is a server-side equivalent to the client stub
- server stub transforms requests comming from the
network into local procedure call
- when local procedure is executed it packs results in a
message and calls send to return it to the client
RPC - parameter passing
- client stub has a function to take parmeters, pack it in a message
and send it to the server stub
- packing parameters into a message is called
parameter marshaling
- sever stub has to unpack the message and take sent parameters
- unpacking parameters from the message is called
unmarshaling
- marshaling and unmarshaling should transform data into neutral formats
- transforation to neutral formats is necessary because different machines
can have differnt byte-ordering rules and other differences
- Intel processors for instance use little endian (numbering bytes
form right to left) and older ARM processors use big-endian
RPC - parameter passing issues
- languages has mostly two types of parameter passing
- copy-by-value
- copy-by-reference
- copy-by-reference (using pointers) is specialy problematic for RPC
- when we copy-by-reference we basically copy the address
in our local address space and when we transfer it to
the server it's there useless
- one part of a solution is to copy these parameters by value if they
would be only read on the server side
RPC example in python
- example implemented on the local mashine
- python has in-built server which can be run through the
script located in bin/rpyc_classic.py of
python installation: python bin/rpyc_classic.py
- on the client side we have a simple program using rpyc library
import rpyc
conn = rpyc.classic.connect('localhost')
conn.execute('print('Hello world");
RPC - Example 2
- in this example client side opens a textfile and prints
lines using print_line function
- client calls a procedure line_count which
is located on the server side
import rpyc
def print_line(string):
print("Line:", repr(string))
proxy = rpyc.connect('localhost', 18861, config={'allow_public_attrs': True})
file_obj = open('textfile.txt')
linecount = proxy.root.line_counter(file_obj, print_line)
print("Number of lines in the file is: ", linecount)
RPC - Example 2 - server side
- server side reads the file
and every time calls client side function to print a line
- we can see that communications is done several times and this
requires intensive use of the network
import rpyc
from rpyc.utils.server import ThreadedServer
class MyService(rpyc.Service):
def exposed_line_counter(self, f_object, function):
for line_num, line in enumerate(f_object.readlines()):
function(line)
return line_num+1
t = ThreadedServer(MyService, port=18861)
t.start()
CORBA - Common Object Request Architecture
- RPC proved to be adequate solution for the develoment of
two-tier client server architectures
- RPC cauldn't provide flexibility and functionality required
by in n-tier applications
- Common Object Request Architecture (CORBA) is offered as a
solution by Object Management Group (OMG)
- CORBA is an architecture that specifies interoperability
between distributed objects on the network
- it is an object-oriented middleware paradigm
- primary feature is interoperability between various
programming languages
- CORBA is based on RPC and extends RPC framework by
object-oriented mechanisms
Object Request Broker (ORB)
- main part of CORBA is Object Request Broker (ORB)
- object residing in a client make remote requests using an
interface to the ORB running on the local machine
- local ORB sends the request to the remote ORB
(which resides on the server) and sends back an object
reference to the requester
- object residing on the client can now make a remote method
invocation of the remote object
- ORB marshals arguments and sends invocation over the
network to the remote object's ORB
- remote object's ORB calls the method locally and sends results
back to the client.
Object Request Broker (ORB) cont.
- services that an object provides are expressed in a
special language - Interface Definition Language (IDL)
CORBA cont.
- currently there are many languages supported by CORBA providers,
the majority of them with C++ and Java and some
other with Smalltalk, Perl, Python, etc.
- some CORBA products are
-
Orbacus - (Java and C++ ORB from Iona Technologies)
-
WebSphere - (application server with an ORB from IBM)
- CORBA showed to have many shortcomings and limitations
when used in Web environments and is supersided by more
compliant technologies (web services)
Web services
- historical overview of Web applications roughly looks as fallows:
- static web pages - static HTML pages represented in
browsers
- dinamic web pages - interactions supported by Thread-based Server-technologies
- Java Servlets
- Java Server Pages (JSP)
- Hypertext Preprocessor (PHP)
- ASP.NET
- these technologies facilitated man-to-machine communication
Web services
- historicaly next step was to standardize machine-to-machine
communication on the Web
- here Web services come into play
Web services
- web service is a distributed application whose components
are executed on distinct devices
- web services provide a common communication platform for
applications built in various programming languages
- language transparency is the key to web service
interoperability
- interoperabilty represents an ability of web services and requesters
to interact seamlessly despite of differences in programming
languages, platforms and supporting libraries
- language transparency is achieved by exchanging data
using XML technologies
- XML supports structured document interchange and processing
Web services cont.
- Web services are tipically based on HTTP protocol
- client can make requests for various web services (servers can
also behave as clients to some other servers)
- Web service features
- loosely coupled - each service exists independently of
other services that make up application
- easier integration - providing easier communication between
organizations
- service reuse - combining services to make a new functionality
- Web services can be "roughtly" devided into two categries:
SOAP (Simple Object Access Protocol)
SOAP is an industry accepted W3C specification for ubiquitous
XML distributed computing infrastructure
- transport-independent messaging protocol
- mechanism for defining the unit of communication
- mechanism for error handling
- messages are XML documents which follow a specific pattern
- root element is known as Envelope element
- header contains rooting data
- body contains the actual message
XML (eXtensible Markup Language)
It's a markup language similar to HTML which is designed to
store and transport data
- XML tags are not predefined as HTML tags
- XML doesn't carry information how data should be presented
- XML is hardware-independent and that's why it's used
for web services
- each tag has it's cooresponding ending tag
<message>
Alice
Bob
This is the place for the message body.
</message>
SOAP message format
<soap:Envelope
xmlns:soap="http://www.w3.org/2003/05/soap-envelope/"
soap:encodingStyle="http://www.w3.org/2003/05/soap-encoding">
...

...
Simplified architecture of SOAP message transmission
WSDL - (Web Service Description Language)
web services have to be described in order to clients know
what they offer (what they do)
- WSDL file is a description of what the web service does
- WSDL file is an XML format for describing all the information
needed to invoke and communicate with a Web service
- WSDL contains:
- Functional description - detail on how the Web
service is invoked, and focuses on details of syntax of the message and how to
configure protocols to deliver message
- nonfunctional description - details secondary for the
message such as security policy and additionaly instructions
- WSDL is automatically generated
UDDI - (Universal Description, Discovery and Integration)
When Web services are made they have to be publish and Web consumers need
some means to search and find them
- UDDI is an XML-based registry of Web services
- UDDI search mechanism can focus on different criteria - business name,
business category, location, URL, etc.
- UDDI can be interogated using SOAP messages and should
provide access to WSDL documents of services which are in it's
directory
- UDDI registries are commonly found in companies where
facilitate easer access to services
SOAP web services - properties
- SOAP web services become a well defined middleware
technology for the Internet
- the use of HTTP made them usable besides Internet
- they become open standards implemented by all main
programming languages
- SOAP web services have been over-engineered
- Additional burden that XML based SOAP messages put on
network communication
- this complexity of SOAP explains the current popularity of RESTful approaches
RESTful Web Services
- Representational State Transfer (REST)
- SOAP is messaging protocol while REST is a style of software
architecture
- REST is an architecture for distributed systems (in which text,
video, graphics and other media are stored across a network and
connected through hyperlinks
- evertything that has an URI is a resource
- RESTful approach is to use HTTP as an API not just as a
transport protocol(in SOAP web services)
- HTTP has its own methods that are suitable for CRUD operations
- RESTful uses HTTP methods as onwn verbs
- GET - Reads an existing resource
- POST - Creates a new resource
- PUT - Updates an existing resource
- DELETE - Deletes an existing resource
REST features
- REST messages are more simple than SOAP messages
- GET and DELETE verbs are used in requests that don't have a body
- GET request, for instance, have no body and
query arguments are contained in the query string
- http://www.students-database.com/students?average-mark<3&studycourse=WISC17
- question mark(?) begins the query string and
attributes which are key-value pairs are separated by ampersand(&)
- POST request has a body but that body can contain arbitrary
XML document (instead of SOAP envelope in SOAP web services)
RESTful web services in Java
- JAX-RS (Java API for RESTful Web Services) is a specification used in Java to
implement RESTful applications
- JAX-RS is an API specification with it's specific annotations
- JAX-RS has serveral implementations such as
Jersey,
RESTEasy
Apache CXF
- Spring framework
on the other hand provides an alternative implemetation of RESTful applications
which doesn't comply to JAX-RS standard
Apache CXF

Henrik Vibskov A visual identity for an eccentric Danish fashion designer A visual identity for the eccentric Danish fashion designer, Henrik Vibskov. I met with Vibskov for my graphic design course in Copenhagen, and I created a visual identity for his brand, which encompasses fashion lines, exhibits, music, and art. Vibskov is famous for transforming his designs into entire universes of stories and eccentricities. The ripple logo reflects the unexpected twist he has on whatever he touches and references the universes he creates by symbolizing the rings of a planet. The posters for the AW17 fashion line use the runway costumes and models' shoes as graphic inspiration. The notebook reflects Vibskov's technique of transforming ordinary objects, in this case college-lined paper, into the extraordinary and peculiar. The individualized business cards allow each employee to choose a shape that represents them, and the Henrik Vibskov logo subtracts and cuts lines into that shape to reflect each person's individuality that brings something new to the brand. The tote bag draws inspiration from plastic 'Thank You' bags. It is a commentary on how Vibskov uses the cheap (plastic bags) to create the high-end (Henrik Vibskov). Process Sheets |

2D constant-density acoustic frequency-domain modeling, linearized modeling and imaging: Modeling
The modeling operator is based on a 9-point mixed-grid discretization of the Helmholtz operator [1]. It solves the system in parallel over frequencies using direct factorization (Matlab's mldivide). Source injection and receiver sampling is done via cubic interpolation. The Jacobian is derived by linearizing the discretized system and its forward and adjoint action is calculated via the adjoint-state method.
The basic syntax of the modeling operator is [D,J] = F(m,Q,model), where
- m is a vector with a gridded slowness-squared model [km^2/s^2],
- Q is a matrix that defines the sources,
- model is a struct with various other parameters,
- D is a vectorized data-cube (receiver x source x frequency),
- J is the Jacobian as SPOT operator.
We illustrate the basic modeling capabilities on a simple layered model.
Contents
Model
We define a simple layered model:
% grid z = 0:20:1000; x = 0:20:2000; % convert to [origin, increment, size] triplet [o,d,n] = grid2odn(z,x); % velocity v = 1500*ones(n); v(z>300,:) = 2000; v(z>700,:) = 2500; % plot figure; imagesc(x,z,v);axis equal tight;colorbar; xlabel('x [m]');ylabel('z [m]');title('velocity [m/s]');
Now, we define a vector with gridded slowness-squared values [km^2/s^2]
m = 1e6./v(:).^2;
Sources/receivers
The sources are defined on a separate grid, which is mapped to the computational grid via adjoint cubic interpolation. A monopole source is then simply defined by putting a single spike on the source grid. For example,
% source grid, 1D grid at z = 15 zsrc = 15; xsrc = 500:25:1500; % point source at z = 15, x = 1225 q = 0*xsrc; q(xsrc==1225) = 1; % define cubic interpolation operator that maps from the model-grid to the % source-grid: L = opKron(opLInterp1D(x,xsrc),opLInterp1D(z,zsrc)); % plot source function on model grid figure; imagesc(x,z,reshape(L'*q(:),n),[-0.01 0.01]);xlim([1200 1300]);ylim([0 50]); colormap([.8 0 0;1 0 0;1 1 1;0 0 1;0 0 .8]); set(gca,'xtick',x,'ytick',z,'xgrid','on','ygrid','on'); hold on;plot(1225,15,'w*'); xlabel('x [m]');ylabel('z [m]');title('monopole source on model-grid');
Each column of the source matrix Q defines one gridded source function. To define a point source on each gridpoint of the source grid, we simply take Q to be an identity matrix:
Q = speye(length(xsrc));
The receivers are defined on a similar grid, and the data is mapped to this grid via cubic interpolation.
Parameters
The struct model contains the following parameters
- model.{o,d,n} - physical grid: z = ox(1) + [0:nx(1)-1]*dx(1), etc.
- model.nb - number of points to add in each direction for absorbing boundary
- model.freq - frequencies in Herz
- model.f0 - peak frequency of Ricker wavelet, 0 for no wavelet.
- model.t0 - phase shift [s] of wavelet.
- model.{zsrc,xsrc} - vectors describing source array
- model.{zrec,xrec} - vectors describing receiver array.
% model grid model.o = o; model.d = d; model.n = n; % absorbing boundary model.nb = [50 50]; % source/receiver grid model.zsrc = zsrc; model.xsrc = xsrc; model.zrec = 5; model.xrec = 0:15:2000; % frequencies in Herz. model.freq = [4:2:15]; % wavelet model.f0 = 10; model.t0 = 0.01;
Data
Having defined al the parameters, we can simply generate data as follows
D = F(m,Q,model,1);
The number of source, receivers and frequencies are given by
nrec = length(model.xrec); nsrc = size(Q,2); nfreq = length(model.freq);
We can now reshape the data into a cube and plot a frequency slice
D = reshape(D,nrec,nsrc,nfreq); figure; imagesc(real(D(:,:,3))); xlabel('source number');ylabel('receiver number');title(['Real part of data @ ' num2str(model.freq(3)) ' Hz']);
Born modeling
We can model linearized data by using the Jacobian. First we define a smoothed model and reflectivity.
% smoothing operator S = opKron(opSmooth(n(2),50),opSmooth(n(1),50)); % smooth model and perturbation m0 = S*m; dm = m - m0; % plot figure; imagesc(x,z,reshape(m0,n));colorbar; xlabel('x [m]');ylabel('z [m]');title('Smooth model [s^2/km^2]'); figure; imagesc(x,z,reshape(dm,n));colorbar; xlabel('x [m]');ylabel('z [m]');title('perturbation [s^2/km^2]');
The Jacobian operator is constructed as follows:
J = oppDF(m0,Q,model,1);
Remember, J is not an explicit matrix. It is simply an object that looks like a matrix to matlab. Constructing it does not require any computation. All the computations are done when multiplying it with a vector.
The linearized data is now simply given by
dD = J*dm; dD = reshape(dD,nrec,nsrc,nfreq); % plot figure; imagesc(real(dD(:,:,3))); xlabel('source number');ylabel('receiver number');title(['Real part of data @ ' num2str(model.freq(3)) ' Hz']);

In the previous post, I spoke about getting your computer ready for you to work, but I didn’t spend much time talking about getting yourself ready to work. In a series of posts, I will cover tools beyond your computer that can help you be a better developer.
As developers, we spend a lot of time at our computers. We obsess over the technical specifications of the newest laptop, and discuss the benefits and drawbacks of the newest library that was released, but we don’t spend much time talking about how we — as human beings in physical bodies — interact with the tools of our trade.
Generally speaking, these days many programmers are working on powerful, lightweight laptops. The freedom of being able to work from anywhere — a coffee shop, an airport, or even sitting on the couch — has led many of us to ditch the notion of large, noisy computer towers in favor of the ultrabook.
As we put away our gargantuan computers of years past, we also traded in our ergonomic desk setups for hunched-over, strained-neck, cramped sitting styles in laps and on table-tops to use our primary tool of the trade. Gone are the keyboard trays, the gel-padded wrist protectors, and the $500 chairs.
The issue at hand is that laptop keyboards are attached to the screen of the laptop, which, when seated at a regular desk, forces the laptop user to look down. This posture consequently rounds the shoulders in wards towards the chest. Keeping the neck and shoulders in this unnatural position for hours at a time can lead to long-term injuries, including RSI (repetitive stress injury), nerve damage, migraines, and more. (For all of the potential risks, ask a professional chiropractor or musculoskeletal specialist).
As you can see in the figure(1) above, there seems to be no decent way to achieve good posture while using a laptop without additional peripherals.
Enter Carolina Morning Designs* and the Japenese-inspired minimalist furniture that Linsi Deyo and her partner Patrick Clark offer for sale on their website.
This type of seating is called “active sitting”, as you engage the core muscles of your abdomen and back to help you stay seated. It is uncomfortable to take a slouched position at the Zen Office.
In addition to the floor position, it is also possible for the Zen Office to be repurposed in other ways. If you prefer to switch between sitting and standing, you can easily use the Zen Office along with a wireless keyboard and mouse to accomplish this.
Having used a gamut of seating situations for computer work, ranging from cardboard-box standing desks, to $22 Ikea hacks for a standing desk, and even yoga balls for active sitting, I can say with confidence that I don’t think I will ever need another desk besides the Carolina Mornings Design Zen Office. Since it breaks back down to two small packages, with no tools required for assembly, I can take it anywhere, and whenever I get tired in one position, I can quickly move to another.
What sort of sitting and standing arrangements have you used for computer work? Do you alternate throughout the day, or just stay in one position?
*I found Carolina Morning Designs while researching sleeping on the floor, as I have been living in a yurt again and in my packing for gSchool have refused to bring a mattress or purchase a new one. If you love sleeping on a firm surface, as I do, check out their modular platform bedframes and other minimalistic sleeping surfaces.

'Disappointed' - The Chelsea and Arsenal legends' verdicts Aston Villa fans will agree with
The Aston Villa defender was left out of the starting XI by Gareth Southgate
by Elliott Jackson, https://www.birminghammail.co.uk/authors/elliott-jackson/Former Chelsea and Arsenal defenders Ashley Cole and Lee Dixon have both admitted they're "disappointed" not to see Tyrone Mings start for England against Montenegro.
The Aston Villa defender impressed for the Three Lions having made his debut against Bulgaria during the last international break.
However, John Stones was selected to replace Mings after his return to fitness, despite his indifferent form for Manchester City.
The former Everton defender joined Harry Maguire at the heart of the defence, with Trent Alexander-Arnold and Ben Chilwell at full-back.
However, having dealt manfully with off-the-pitch racist abuse during the trip to Bulgaria and putting in a strong performance, both Cole and Dixon believe that Mings should've started once again alongside Maguire against Montenegro.
Speaking to ITV before the match, Dixon said: "He (Stones) is a good player, there is no doubt about that but he has lost his way a little bit. Does he seem like the character that can get himself back to how good he was?
"He plays on confidence and at the minute he's in and out at Man City. I'm disappointed, we've just been talking about Mings not playing again.
"A second game, a run out at Wembley, to build a partnership and just see if whether he going to be the one to step into the gap if there are injuries. I'm a bit disappointed he's not playing tonight."
Cole, who has 107 caps for England, added: "I think he played with quality, a little bit of arrogance, confidence.
"I think he fitted right in, he didn't look like a newbie to the international stage.
"We're probably a little bit disappointed he didn't play again today."

Challenge 23 (50,000 XP)
Empowered Attacks. Maegera’s slam attacks are treated as magical for the purpose of overcoming resistance and immunity to damage from nonmagical attacks.
Fire Aura. At the start of each of Maegera’s turns, each creature within 30 feet of it takes 35 (10d6) fire damage, and flammable objects in the aura that aren’t being worn or carried ignite. A creature also takes 35 (10d6) fire damage from touching Maegera or from hitting it with a melee attack while within 10 feet of it, and a creature takes that damage the first time on a turn that Maegera moves into its space. Nonmagical weapons that hit Maegera are destroyed by fire immediately after dealing damage to it.
Fire Form. Maegera can enter a hostile creature’s space and stop there. It can move through a space as narrow as 1 inch wide without squeezing if fire could pass through that space.
Illumination. Maegera sheds bright light in a 120-foot radius and dim light in an additional 120 ft..
Innate Spellcasting. Maegera’s can innately cast fireball (spell save DC 19) at will, requiring no material components. Maegera’s spell casting ability is Charisma.
Magic Resistance. Maegera has advantage on saving throws against spells and other magical effects.
Actions
Multiattack. Maegera makes three slam attacks.
Slam. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 15 (3d6 + 5) bludgeoning damage plus 35 (10d6) fire damage
Legendary Actions
The maegera the dawn titan can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time, and only at the end of another creature’s turn. The maegera the dawn titan regains spent legendary actions at the start of its turn.
Quench Magic. Maegera targets one creature that it can see within 60 feet of it. Any resistence or immunity to fire damage that the target gains from a spell or magic item is suppressed. The effect lasts until the end of Maegera’s next turn.
Smoke Cloud (Costs 2 Actions). Maegera exhales a billowing cloud of hot smoke and embers that fills a 60 feet cube. Each creature in the area takes 11 (2d10) fire damage. The cloud lasts until the end of Maegera’s next turn. Creatures completely in the cloud are blinded and can’t be seen.
Create Fire Elemental (Costs 3 Actions). Maegera’s hit points are reduced by 50 as part of it separates and becomes a fire elemental with 102 hit points. The fire element appears in an unoccupied space within 15 feet of Maegera and acts on Maegera’s initiative count. Maegera can’t use this action if it has 50 hit points or fewer. The fire element obeys Maegera’s commands and fights until destroyed.

Tutoring Plus is a Cambridge based non-profit that serves under privileged children through education and enrichment programs. I, along with two web developers and two photographers, were tasked with redesigning their site in order to increase student enrollment, volunteer participation and increase donor funding
This was a dual track project with both usability need as well as a visual redesign.
For this redesign, I served as the UX/UI Designer, as well as the project manager between the internal team (developers and photographers) and the main client contact.
Usability goals for this project included creating clear call to actions that would be consistent across the site, analyzing content and revising the site map, simplifying the lengthy volunteer and participant form, and providing an easy pathway to donation on each page.
The UX process included user research resutling in the creation of user personas and scenarios, a revised sitemap, low fidelity wireframes, and annotated wireframes for developers to work off of.
Visual goals were centered on creating a cleaner look and feel, while maintaining a fun, yet professional, tone.
In order to make the site more visually appealing, while maintaining brand recognition, the original blue, green and orange color palette was modernized. Instead of neon hues of each of these colors, which felt outdated and aggressive, bright colors in the same scheme were chosen to maintain the upbeat tone of the group.

Core Concepts for Beginners
Welcome to Travis CI! This page provides some contexts and terminologies used throughout the platform and documentation, which might be helpful, if you are new here or new to Continuous Integration (CI).
Continuous Integration is the practice of merging in small code changes frequently - rather than merging in a large change at the end of a development cycle. The goal is to build healthier software by developing and testing in smaller increments. This is where Travis CI comes in.
As a continuous integration platform, Travis CI supports your development process by automatically building and testing code changes, providing immediate feedback on the success of the change. Travis CI can also automate other parts of your development process by managing deployments and notifications.
When you run a build, Travis CI clones your GitHub repository into a brand-new virtual environment, and carries out a series of tasks to build and test your code. If one or more of those tasks fail, the build is considered broken. If none of the tasks fail, the build is considered passed and Travis CI can deploy your code to a web server or application host.
CI builds can also automate other parts of your delivery workflow. This means you can have jobs depend on each other with Build Stages, set up notifications, prepare deployments after builds and many other tasks.
In the Travis CI documentation, some common words have specific meanings:
script
phase is non-zero.install
phase, comes before the script
phase, which comes
before the optional deploy
phase.
The build is considered broken, when one or more of its jobs complete with a state that is not passed:
before_install
, install
, or
before_script
phase returned a non-zero exit code. The job stops immediately.
script
phase returned a non-zero exit code. The job continues to
run until it completes.Our Common Builds Problems page is a good place to start troubleshooting why your build is broken.
Travis CI offers a few different infrastructure environments, so you can select the setup that suits your project best:
sudo
, setuid
, and setgid
.
Check out more information on the Ubuntu Linux Build
Environment.More details on our build environments are available in our CI Environment documentation.
Now that you’ve read the basics, head over to our Tutorial for details on setting up your first build!


Ejection fraction is a measurement, expressed as a percentage, of how much blood the left ventricle pumps out with each contraction. An ejection fraction of 60 percent means that 60 percent of the total amount of blood in the left ventricle is pushed out with each heartbeat.
Serum creatinine is an important indicator of kidney health because it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys. Creatinine itself is produced via a biological system involving creatine, phosphocreatine, and adenosine triphosphate.

We expect about 12 homeworks, so each one is worth 0.6/12 = 0.05 or
50 permilles (promilles, ‰). The actual promilles used for grading
may differ, if the total number of homeworks is not exactly 12; or one homework is
considered bigger (and weighs more) than another.
Time estimates are not meant to be precise or useful. They are
a relative measure; for example, an 16h assignment for a typical student
would require considerably more time and energy than a 2h assignment.

These worksheets are used in the lab sessions on Wednesdays and Fridays.


1.) Masks on: Within any given area of the paintball field, either all players/officials/spectators
masks must be on, or all players markers must either have a barrel block in place or be
disconnected from their gas source, to ensure that a paintball cannot be fired from any nearby
marker and cause eye injury.
2.) Minimum Distance: A minimum distance rule; such as 15 feet (4.5 m), whereby players
cannot shoot an opponent if they are closer than this distance.
3.) Hit: A player is hit if a paintball leaves a solid, quarter-sized mark anywhere on the player’s
body or equipment
4.) Overshooting: We discourage players from overshooting (also regarded as bonus balling,
“overkill” or lighting up), which is to repeatedly shoot a player after they are eliminated from the
game. It is also considered overshooting if a player knew the opponent was eliminated but
continued to shoot, disregarding the safety of the opposing player and risking dangerous injury
to others.
5.) Ramping: Ramping is a feature of many electronic markers, where after a certain number of
rapid shots or upon a threshold rate-of- fire being achieved by the player, the gun will begin firing
faster than the trigger is being pulled. Ramping of rate of fire is prohibited.
6.) Wiping: Players may attempt to cheat by wiping paint from themselves, to pretend they were
not hit and stay in the game. If caught, “wipers” are generally called out of the game
7.) Non-contact: Players are generally prohibited from physically contacting other players, such
as colliding with them, physically restraining them, and especially using fists, feet, protective
gear or the markers themselves to hit other players.
8.) All equipments will be provided by the programme volunteers

controlP5 is a controller library for processing that works in authoring, application, and applet mode. controllers can be added to a processing sketch itself, to separate control windows, and can be organized in tabs.
all controllers are drawn on top of a processing sketch. several key combinations allow the user to show and hide the user interface, save and load. controlP5 setups can be saved and loaded locally or to/from a server.
the position of a controller can be adjusted during runtime by moving a controller with the ALT-key down.
the controlP5 source code repository is available at sourceforge at code.google.com/p/controlp5/source/browse/.
since the security regulations for applets are very high and strict, you need to make fields and functions that you control with controlP5 public in your code.

Slack GDPR
Slack was quite proactive in preparing for the European Commission’s enactment of the General Data Protection Regulation (GDPR), seemingly doing everything that is required to comply with the law and also to inform customers about how Slack will help them comply. This is includes table-stakes efforts such as creating a dedicated GDPR website and entering into Data Processing Addenda with both its customers and its vendors.
In order to reassure customers that their data will be safe with Slack, and that their use of Slack complies with GDPR guidelines, Slack also uses its GDPR website to highlight its security certifications and practices, as well as its certification under both the EU-US Privacy Shield and Swiss-US Privacy Shield frameworks. The idea here is to let users know that they should be largely free of any potential GDPR violations resulting from their usage of Slack, because Slack is doing everything it can to ensure that personal data is protected.
However, Slack also goes an extra step by pointing users to tools and features in the product that will help them comply with GDPR requirements around data management:
- Import and export tools
- Profile deletion tool
- Workspace settings center
In terms of GDPR, the profile deletion tool is probably the most directly related and also the most interesting. It allows members (or former members) of corporate Slack channels to request that their information be deleted from that company’s account, per GDPR requirements around deletion of personal data should a subject request it. If a data subject can’t reach their Slack administrator, they can also reach out to Slack directly.
Notably, though, while Slack will delete data related to a user’s profile, it will not delete that user’s activity in the channel. This might seem like an incomplete approach to data deletion, Slack explains that messages, posts and mentions will remain so as to not break the product for other users. Additionally, Slack might be required to save that type of data for legal purposes, and the GDPR allows continued processing of data for that reason.
If there’s one area where Slack appears to be missing the mark on GDPR compliance, it is with its list of subprocessors (i.e., other vendors that Slack uses to process personal data). Although this is an issue not applicable to Slack alone, it seems unlikely the company is only processing personal data with a total of five other vendors. The tools listed on their StackShare page also include Google Analytics, Respondly, Fastly etc, maybe they aren’t using these tools any longer or maybe they just have a different definition of processing personal data.
While this might be accurate with regard to Slack’s role as a data processor on behalf of customers, Slack also acts as a controller of personal that it collects for billing, sales and other business purposes. In this role, one can assume Slack might utilize vendors such as Google (G Suite), Salesforce, Stripe and other business software that process personal data.
