This tutorial is out-dated (written in 2013). Please check this tutorial instead: https://codelabs.developers.google.com/codelabs/webrtc-web/#0
Explains how to
- use WebRTC peer connection API (RTCPeerConnection.js)
- write one-to-one video sharing application
- use socket.io or websockets for signaling
Suggestions
- If you're newcomer, newbie or beginner; you're suggested to try RTCMultiConnection.js or DataChannel.js libraries.
-
Remember:
RTCPeerConnection.js
is documented here. - Another recommended tutorial is: How to use WebRTC PeerConnection?

First of all; you need to reference RTCPeerConnection.js library: <script src="https://www.webrtc-experiment.com/RTCPeerConnection-v1.5.js"></script> |
OffererNow assume that you are creating "offer"...you need to use this code to create offer sdp: var peer = RTCPeerConnection({ attachStream : clientStream, onICE : function (candidate) {}, onRemoteStream : function (stream) {}, onOfferSDP : function(sdp) {} }); Here is the short explanation of above code ↑
Now assume that other peer generated answer sdp and sent to you; you can pass that sdp to this function:
Now assume that other peer gathered ICE and sent to you; you can pass that ICE to this function:
peer.addICE({ sdpMLineIndex : candidate.sdpMLineIndex, candidate : candidate.candidate }); |
Answerer
99% process is the same for peer who "creates answer sdp"; the only difference is: for that peer you don't need "
var peer = RTCPeerConnection({
attachStream : clientStream,
onICE : function (candidate) {},
onRemoteStream : function (stream) {},
// see below two additions ↓
offerSDP : offer_sdp,
onAnswerSDP : function(sdp) {}
});
Let me elaborate:
For ICE sent by other peer; you need to do same thing:
peer.addICE({ sdpMLineIndex : candidate.sdpMLineIndex, candidate : candidate.candidate }); |

How to write a realtime WebRTC app using socket.io?First of all; you need to reference socket.io.js: <script src="https://www.webrtc-experiment.com/dependencies/socket.io.js"></script> Now, open socket and transmit your request (e.g. room) until a participant found: var socket = io.connect('http://pubsub.pubnub.com/webrtc-app', { publish_key : 'demo', subscribe_key : 'demo', ssl : true, /* <<< for HTTPS */ channel : 'WebRTC App' }); socket.on('connect', onconnect); socket.on('message', oncallback); /* socket is opened: it is your time to transmit request! */ function onconnect() {} /* got response */ function oncallback(response) {} Above code is same for both: offerer and answerer. OffererNow, assume that it is "offerer" who transmits request for participant to join him. He will not create "offer sdp" until he receive "join request" from his participant. Following code is for offerer (95% part of this code can be used for Answerer): function onconnect() { transmitRequest(); } var userID = 'offerer'; /* unique ID to identify this user */ var foundParticipant = false; function transmitRequest() { socket.send({ userID : userID, type : 'request to join' }); // Transmit "join request" until participant found !foundParticipant && setTimeout(transmitRequest, 1000); } function oncallback(response) { // Don't get his own messages if(response.userID == userID) return; // if participant found if(response.participant) { foundParticipant = true; // create offer and send him offer sdp createOffer(); } // answer sdp sent to you: complete handshake if(response.firstPart || response.secondPart) { processAnswerSDP(response); } } var peer; function createOffer() { peer = RTCPeerConnection({ /* function(offer_sdp) {}, */ onOfferSDP: sendOfferSDP, onICE: function(candidate) { socket && socket.send({ userID: userID, candidate: { sdpMLineIndex: candidate.sdpMLineIndex, candidate: JSON.stringify(candidate.candidate) } }); }, onRemoteStream: function(stream) { if(stream) video.src = webkitURL.createObjectURL(stream); }, attachStream: clientStream }); } // send offer sdp function sendOfferSDP(sdp) { var sdp = JSON.stringify(sdp); /* because sdp size is larger than what pubnub supports for single request... /* that's why it is splitted in two parts */ var firstPart = sdp.substr(0, 700), secondPart = sdp.substr(701, sdp.length - 1); /* transmitting first sdp part */ socket.send({ userID: userID, firstPart: firstPart }); /* transmitting second sdp part */ socket.send({ userID: userID, secondPart: secondPart }); } var answerSDP = {}; // got answer sdp, process it function processAnswerSDP(response) { if (response.firstPart) { answerSDP.firstPart = response.firstPart; if (answerSDP.secondPart) { var fullSDP = JSON.parse(answerSDP.firstPart + answerSDP.secondPart); peer.addAnswerSDP(fullSDP); } } if (response.secondPart) { answerSDP.secondPart = response.secondPart; if (answerSDP.firstPart) { var fullSDP = JSON.parse(answerSDP.firstPart + answerSDP.secondPart); peer.addAnswerSDP(fullSDP); } } } That was all you need to do for offerer side. AnswererFor answerer: you write 95% same code like offerer; there is just a little bit difference.
On the "Answerer" side; when user click "join" button; send a message to Offerer to tell him that you're ready to get "offer sdp" from him. var userID = 'answerer'; socket && socket.send({ participant: true, userID: userID }); Here is the function that creates "answer sdp": function createAnswer(offer_sdp) { peer = RTCPeerConnection({ /* you need to pass offer sdp sent by offerer */ offerSDP: offer_sdp, onAnswerSDP: sendAnswerSDP, onICE: onICE, onRemoteStream: onRemoteStream, attachStream: clientStream }); } For answerer: socket "callback" function will be like this: function oncallback(response) { if(response.userID == userID) return; // you can show a "join" button or you can send participant request if(response.type && response.type == 'request to join') {} // offer sdp sent to you by offerer if(response.firstPart || response.secondPart) { processAnswerSDP(response); } } Remember: you don't need to call "peer.addAnswerSDP(fullSDP)" in processAnswerSDP function; instead call createAnswer like this: createAnswer(fullSDP); You MUST get client stream before creating offer or answer. |
How to write same app in WebSocket?For WebSocket, you need to reference websocket.js instead of referencing socket.io.js <script src="https://www.webrtc-experiment.com/dependencies/websocket.js"></script> You need to create socket like this: "use strict" var socket = new WebSocket('wss://pubsub.pubnub.com/demo/demo/webrtc-app'); socket.onmessage = onconnect; socket.onopen = function(event) { oncallback(event.data); }; All other things are 100% same like above code.

Supplyframe and Cadence collaborate on cloud-based PCB library
by Alex McCarthySupplyframe subsidiary company SamacSys has completed an integration with Cadence Design Systems’s Allegro and OrCAD PCB design tool suites.
This collaboration expands on the Cadence OrCAD Capture Cloud and the Allegro System Capture electrical engineering design platform by directly integrating the SamacSys platform of free design resources, including PCB footprints, schematic symbols and 3D models for more than 15 million components.
“Collaborating with Cadence to integrate our eCAD model platform within their next-generation Allegro System Capture and OrCAD Capture products is extremely exciting,” said Alex MacDougall, CEO at SamacSys. “Component library management has now been extended to allow importing models into a design with a single click.
Our collaboration with Cadence helps Allegro and OrCAD users save critical time during the design process.”
“We wanted to make our new generation of Allegro System Capture tools as intuitive and future-proof as possible. Giving our users direct access to the SamacSys eCAD model platform within the design environment helps the design process become truly seamless,” said Dan Fernsebner, product marketing director of PCB solutions at Cadence.
“Designers using the Allegro and OrCAD tools can now benefit from the convenience and confidence of accessing high-quality PCB models for components across the entire industry from SamacSys, without having to waste valuable time.”

UBF(B)
UBF(B) - quick summary
UBF(B) has:
- A type system
- Strings are written enclosed in double quotes, thus:
- A protocol description language
- The protocol description language
allows allows us to specific client server interaction in terms of a non-deterministic finite state machine.
The type system
The notation:
- int() Means a UBF(A) integer.
- string() Means a UBF(A) string.
- constant() Means a UBF(A) constant.
- bin() Means a UBF(A) binary data item.
- X() Means an Object of type X
UBF(A) literals are written as follows:
- "..." - denotes a UBF(A) string.
- [a-z][a-zA-Z0-9_]* - denotes a UBF(A) constant.
- [-][0-9]+ - denotes a UBF(A) integer.
Complex types are defined recursively:
- {T1, T2, ..., Tn}
- Is the tuple type if T1 .. Tn are types.
We say that {X1, X2, ..., Xn} is of type
{T1, T2, ..., Tn} if X1 is of type T1, X2 is of type T2, ... and
Xn is of type Tn.
- [T]
- Is the list type if T is a type.
We say that # Xn & Xn-1 & ... X2 & x1 is of type
[T] if all Xi are of type T.
- T1 | T2
- Is the alternation type if T1 and T2 are types.
We say that X is of type
T1 | T2 if X is of type T1 or if
X is of type T2.
New types
New types are introduced in UBF(B) with the notation:
+TYPE X() = Type
Examples:
+TYPE person() = {person, firstname(), lastname(), sex(), age()}.
+TYPE firstname() = string().
+TYPE lastname() = string().
+TYPE age() = int().
+TYPE sex() = male | female.
+Type people() = [person()].
This type schema defines a number of different types.
For example, it is easily seen that:
'person' >p
# {p "jim" "smith" male 10} &
# {p "susan" "jones" female 14} & $
Is of type people().
Note that UBF(B) type is a language independent type schema.

Tension in BHU Campus after Veer Savarkar’s defaced
Varanasi: Tension prevailed on the campus of the Banaras Hindu University (BHU) on Tuesday after a photograph of nationalist leader Veer Savarkar was defaced. The incident took place in the political science department where photographs of several nationalist leaders, including Mahatma Gandhi and B.R. Ambedkar, adorn the walls.
The incident came to light on Tuesday morning when students of M.A. first year reached their classroom and saw the photograph of Savarkar lying on the ground. The miscreants had also splashed ink on the photograph.
Angry students immediately sat on a ‘dharna’. Senior BHU officials have condemned the incident and have set up a three-member committee to probe the incident. A heavy deployment of police has been made on the campus to prevent the fallout of the incident. (IANS)

A highly conserved 76-amino acid peptide universally found in eukaryotic cells that functions as a marker for intracellular PROTEIN TRANSPORT and degradation. Ubiquitin becomes activated through a series of complicated steps and forms an isopeptide bond to lysine residues of specific proteins within the cell. These "ubiquitinated" proteins can be recognized and degraded by proteosomes or be transported to specific compartments within the cell. (mesh:D025801)

See file elf_section_header_table.lem for relevant definitions and types.
An object file's section header table lets one
locate all the file's sections.
The section header table is an array of Elf32_Shdr
or Elf64_Shdr
structures
as described below.
A section header table index is a subscript into this array.
The ELF header's e_shoff
member gives the byte offset from the beginning of the
file to the section header table.
e_shnum
normally tells how many entries the section header table contains.
e_shentsize
gives the size in bytes of each entry.
If the number of sections is greater than or equal to
SHN_LORESERVE
(0xff00
), e_shnum
has the value SHN_UNDEF
(0
) and the
actual number of section header table
entries is contained in the sh_size
field of
the section header at index 0
(otherwise, the sh_size
member of the initial entry
contains 0
).
Some section header table indexes are reserved in contexts
where index size is restricted, for example, the st_shndx
member of a symbol table entry and the e_shnum
and
e_shstrndx
members of the ELF header.
In such contexts, the reserved values do not represent actual
sections in the object file. Also in such contexts, an escape
value indicates that the actual section
index is to be found elsewhere, in a larger field.

The contents of the initial entry are specified later in this
section.

The section header table does not
contain entries for the reserved indexes.
Sections contain all information in an object file except the ELF header, the program header table, and the section header table. Moreover, object files' sections satisfy several conditions.
Figure 4-8: Section HeaderSee Lem record types elfXX_section_header_table_entry for XX=32,64 for implementations of the above records in elf_section_header_table.lem. See also types elfXX_section_header_table for XX=32,64 for types representing linked lists of section header table entries.

Currently, only 0 and positive integral powers of two are allowed.
Values 0 and 1 mean the section has no alignment constraints.
See functions is_elfXX_addr_addralign_correct for XX=32,64 for this test.

SHT_SYMTAB
provides symbols for link editing, though it may also be
used for dynamic linking.
As a complete symbol table, it may contain many symbols unnecessary
for dynamic linking.
Consequently, an object file may also contain a SHT_DYNSYM
section, which holds a minimal set of dynamic linking symbols,
to save space.
See ``Symbol Table'' below
for details.

.
The section is an array of Elf32_Word
values.
Each value corresponds one to one with a symbol table entry
and appear in the same order as those entries.
The values represent the section header indexes against which
the symbol table entries are defined.
Only if the corresponding symbol table entry's st_shndx
field
contains the escape value SHN_XINDEX
will the matching Elf32_Word
hold the actual section header index;

If a flag bit is set in sh_flags
,
the attribute is ``on'' for the section.
Otherwise, the attribute is ``off'' or does not apply.
Undefined attributes are set to zero.
SHF_WRITE
SHF_ALLOC
SHF_EXECINSTR
SHF_MERGE
SHF_STRINGS
flag is also set,
the data elements in the section are of a uniform size.
The size of each element is specified in the section
header's sh_entsize
field.
If the SHF_STRINGS
flag is also set,
the data elements consist of null-terminated character strings.
The size of each character is specified in the section
header's sh_entsize
field.
Each element in the section is compared against other elements in sections with the same name, type and flags. Elements that would have identical values at program run-time may be merged. Relocations referencing elements of such sections must be resolved to the merged locations of the referenced values. Note that any relocatable values, including values that would result in run-time relocations, must be analyzed to determine whether the run-time values would actually be identical. An ABI-conforming object file may not depend on specific elements being merged, and an ABI-conforming link editor may choose not to merge specific elements.
SHF_STRINGS
sh_entsize
field.
SHF_INFO_LINK
sh_info
field of this section header holds a section
header table index.
SHF_LINK_ORDER
sh_link
field of this section's header references
another section (the linked-to section).
If this section is combined with other
sections in the output file, it must appear in the same
relative order with respect to those sections, as the linked-to section
appears with respect to sections the linked-to section is combined with.
SHF_OS_NONCONFORMING
sh_type
value
or contains sh_flags
bits in the OS-specific ranges for
those fields, and a link editor processing this section does not
recognize those values, then the link editor should reject
the object file containing this section with an error.
SHF_GROUP
SHT_GROUP
.
The SHF_GROUP
flag may be set only for sections contained
in relocatable objects (objects with the ELF header e_type
member set to ET_REL
).
See below for further details.
SHF_TLS
SHF_COMPRESSED
All relocations to a compressed section specifiy offsets to the uncompressed section data. It is therefore necessary to decompress the section data before relocations can be applied. Each compressed section specifies the algorithm independently. It is permissible for different sections in a given ELF object to employ different compression algorithms.
Compressed sections begin with a compression header structure that identifies the compression algorithm.
Figure 4-12: Compression HeaderThe compression header record types above are captured as Lem records elfXX_compression_header for XX=32,64 in elf_section_header.lem.
typedef struct { Elf32_Word ch_type; Elf32_Word ch_size; Elf32_Word ch_addralign; } Elf32_Chdr; typedef struct { Elf64_Word ch_type; Elf64_Word ch_reserved; Elf64_Xword ch_size; Elf64_Xword ch_addralign; } Elf64_Chdr;

.
ch_addralign

.
The sh_size
and sh_addralign
fields of the section
header for a compressed section reflect the requirements of the
compressed section. The ch_size
and ch_addralign
fields in the compression header provide the corresponding values for the
uncompressed data, thereby supplying the values that sh_size
and
sh_addralign
would have had if the section had not been
compressed.
The layout and interpretation of the data that follows the compression header
is specific to each algorithm, and is defined below for each value of
ch_type
. This area may contain algorithm specific parameters
and alignment padding in addition to compressed data bytes.
A compression header's ch_type
member specifies the
compression algoritm employed, as shown in the following table.

symbol (binding STB_LOCAL ). |
SHT_GROUP |
The section header index of the associated symbol table. | The symbol table index of an entry in the associated symbol table. The name of the specified symbol table entry provides a signature for the section group. |
SHT_SYMTAB_SHNDX |
The section header index of the associated symbol table section. | 0 |
sh_type
or sh_flags
fields, the link editor should combine those
sections as described below.
If the section's sh_flags
bits include the attribute
SHF_OS_NONCONFORMING
, then the section requires
special knowledge to be correctly processed, and the link editor should
reject the object containing the section with an error.
Unrecognized sections that do not have the
SHF_OS_NONCONFORMING
attribute, are combined in a two-phase
process. As the link editor combines sections using this process,
it must honor the alignment constraints of the
input sections (asserted by the sh_addralign
field),
padding between sections with zero bytes, if necessary, and producing
a combination with the maximum alignment constraint of its
component input sections.
SHF_MERGE
and SHF_LINK_ORDER
). When not otherwise constrained,
sections should be emitted in input order.
Non OS-specific processing (e.g. relocation) should be applied to unrecognized section types. An output section header table, if present, should contain entries for unknown sections. Any unrecognized section attribute flags should be removed.
A section of type SHT_GROUP
defines such a grouping
of sections. The name of a symbol from one of the containing
object's symbol tables provides a signature for the section group.
The section header of the SHT_GROUP
section specifies
the identifying symbol entry, as described above:
the sh_link
member contains the section header index
of the symbol table section that contains the entry.
The sh_info
member contains the symbol table index of
the identifying entry. The sh_flags
member of the section header contains 0
.
The name of the section (sh_name
) is not specified.
The referenced signature symbol is not restricted. Its containing symbol table section need not be a member of the group, for example.
The section data of a SHT_GROUP
section is an array
of Elf32_Word
entries. The first entry is a flag word.
The remaining entries are a sequence of section header indices.
See functions obtain_elfXX_section_group_indices for XX=32,64 in elf_section_header_table.lem that extract section group indices from a section header with type SHT_GROUP along with the section group flag.
The following flags are currently defined:
| Name | Value |
|---|---|
GRP_COMDAT |
0x1 |
GRP_MASKOS |
0x0ff00000 |
GRP_MASKPROC |
0xf0000000 |
GRP_COMDAT
GRP_MASKOS
GRP_MASKPROC
The section header indices in the SHT_GROUP
section
identify the sections that make up the group. Each such section
must have the SHF_GROUP
flag set in its sh_flags
section header member. If the linker decides to remove the section
group, it must remove all members of the group.
To facilitate removing a group without leaving dangling references and with only minimal processing of the symbol table, the following rules must be followed:
STB_GLOBAL
or STB_WEAK
binding that is defined relative to one of a group's sections,
and that is contained in a symbol table section
that is not part of the group,
must be converted to an undefined symbol
(its section index must be changed to SHN_UNDEF
)
if the group members are discarded.
References to this symbol table entry from outside the group are allowed.
STB_LOCAL
binding
that is defined relative to one of a group's sections,
and that is contained in a symbol table section
that is not part of the group,
must be discarded if the group members are discarded.
References to this symbol table entry from outside the group are not allowed.

With a small group, compare the words you wrote down in your Vocabulary Journals.
Select a word and complete one of the vocabulary handouts using your selected word.
TEACHING STRATEGIES AND DECISIONS
To cement understanding, it is important to have students interact meaningfully with new words. Consider using the new words in any number of the following exercises:
STUDENT SUPPORT AND DIFFERENTIATION
As students learn more vocabulary, it is important to provide opportunities to use the words in meaningful contexts, such as those activities mentioned above. These opportunities provide students, particularly English learners, a tremendous chance to increase their cognitive academic language proficiency (CALP). Students, particularly English learners, often employ basic interpersonal communicative skills (BICS). You might combine new vocabulary with sentence starters, such as those found in the Academic Discussion Reference Guide, to provide opportunities for English learners to practice using academic language in the classroom.
In your Learning Log, respond to the following quote in a quick-write:
[inset]
It was fear of himself, lest he [Okonkwo] should be found to resemble his father.(p. 17)
[inset:end]
TEACHING STRATEGIES AND DECISIONS
You might begin the class by briefly discussing the questions from the previous lesson.
You can inform students that they do not need to limit their responses to the listed questions; they are free to respond in any way they like.
STUDENT SUPPORT AND DIFFERENTIATION
You might complete your own quick-write as students write and share with their groups. You can present your writing where it is visible to the class. It is important that students see your writing in its unfinished and unrevised form, as it will help them write freely during these activities.

ABOUT THE AUTHOR, CONCEPT, TEXT, TOPIC
The Attending to Details Tool supports and guides a process for preparing to read, reading, and initially reacting to a text. This is a helpful process to internalize when you are working with a complex text that might require multiple reads, or one that is being read over a long period. Using this tool usually begins with a guiding question or reading purpose to determine which textual details to notice and annotate.
TEACHING STRATEGIES AND DECISIONS
This is the first time that students use an Attending to Details Tool in this unit, so you might explain its purpose and organization and model how students might use it to move from key details to a text-based observation that expresses their developing understanding of the text.
In this group activity, students might struggle with the meanings of some of the proverbs in the text.
STUDENT SUPPORT AND DIFFERENTIATION
This unit, like all units in the Odell Education High School Literacy Program, employs a suite of tools and resources from the Odell Education Literacy Toolbox as well as tools specific to the unit’s content and instructional sequences. Students can be supported throughout the unit by using materials from the Literacy Toolbox, beyond those that are referenced in the unit. Tools are graphic organizers that support students’ reading and writing by helping them think through text, find pertinent textual details, and develop ideas for their writing. Note that many, such as the Analyzing Relationships Tool and the Forming Evidence-Based Claims Tool are text agnostic—they are designed to be used with any text. Others, such as some note-taking tools, have instructions or structures that are specific to the unit topic or text. These tools help students develop and internalize analytical processes. Since they are scaffolds, they can be assigned at your discretion, or students might develop their own system for using them if they encounter difficult sections of text. See the Tools Reference Guide for a list of core tools.
Reference guides provide centralized explanations and examples of concepts and processes common to English language arts. They make important connections to the pertinent tools and provide additional resources related to the concept. The Assessing Sources Reference Guide provides a process to assess sources for bias, credibility, and accuracy, and the Tone Reference Guide provides information for understanding and identifying tone in a text. While activities suggest when to use reference guides during instruction, you might refer students to them throughout the unit to reinforce understanding around a particular concept or process.
Tools and reference guides specific to lessons and activities can be found in their respective Materials tabs. The teaching notes might also suggest tools or reference guides as additional supports for students.

Despite the limited execution time, and the relatively high level of noise, the success of near-time quantum computing seems to be at the reach of our fingertips thanks to the intimate collaboration between classical and quantum computing. Cloud architectures leveraging colocation of classical and quantum resources, enable applicable fast, iterative dynamic workflows, where new circuits are created on the fly, according to the results of classical computations.
Introduced by IBM Quantum, Qiskit Runtime is a new model of execution aiming at fulfilling the promises of near-time quantum computing by executing hybrid classical and quantum Python programs.
The Hackathon is open to all people, proffessionals, undergraduate, and postgraduate students from Universities, companies and institutions worldwide who are 18 years and older. There is an specific category for students where participants can count on expert advice through coachers.
Read more about team formationIntroduced by IBM Quantum, Qiskit Runtime is a new model of execution aiming at fulfilling the promises of near-time quantum computing by executing hybrid classical and quantum Python programs.
We challenge the participants to create innovative cloud services on top of custom quantum programs or to find novel applications for the Qiskit Runtime's built-in library.
Quantum computers allow to evaluate kernels to be used in Support Vector Machines (SVM) on exponentially large feature spaces. The QKA Runtime allows to align to and evaluate the kernel for given data in the cloud and uses is it for classification tasks such as fraud detection.
Find the ground state of a Hamiltonian via a parametrized quantum circuit. A classical optimizer is used to find the circuit parameters. Applictions ranges from finding groundstates in quantum chemistry, to finding solutions to combinatorial optimization problems.
A variant of the above particularly suited for combinatorial optimization where the circuits are constructed with some convergence guarantees if the circuits could be made long enough.
In addition to using the built-in programs, you can come up with your own Qiskit Runtime programs that can help you and others accelerate their research. Much like the existing built-in programs, your new program will benefit the most from the Qiskit Runtime architecture if it requires iterative quantum/classical processing.
By participating in the IEEE SERVICES 2021 hackathon, we all abide by the Qiskit Code of Conduct, IEEE Code of Conduct and IEEE Code of Ethics

I took the plunge and bought a domain from Namecheap for my Synology NAS. As an added perk I’ve even created a subdomain for my Tumblr blog :-)
I’ll document the steps here in case anyone else has a similar setup and wants to do the same:
All in all, it was very straight forward and a fun weekend project!


public interface DObjectBuilder
DObjectShell
).
Constructs the associated fields and, where required, the field-viewers that enable the OM to provide the client with un-editable views of specific fields where appropriate.
The final field-configuration operations, involving the setting-up of appropriate slot-bindings, are not performed until after the object has been constructed, since certain attributes involved in this process are by default derived from the Java variables to which the fields are assigned after construction.
Hence, any required field-initialisations (setting of initial
values or addition of listeners) must be performed via the
DObjectInitialiser.initialise()
method on an appropriate
DObjectInitialiser
object, which can be specified via
the addInitialiser(uk.ac.manchester.cs.hobo.modeller.DObjectInitialiser)
method.
In order for a Java variable to provide the default attribute-values for a specific field, the variable in question must be an instance-variable on the OM object itself, must be both "public" and "final", and the value must be either the field itself or a viewer for the field.
For each field, unless the "container-class", "field-name" and
"editability" attribute-values have been explicitly specified
(via the appropriate methods) then they will be derived
automatically from the relevant Java variable, assuming that it
exists. The field-name will be taken directly from the variable
name, and the "assertions-editability" status will be derived from
the variable type. For DField
-represented variables the
status will be the default IEditability.CONCRETE_ONLY
,
and for DFieldViewer
-represented variables the status will
be IEditability.NONE
. The "queries-editability" status
will always will be the default IEditability.FULL
. The
"slot-label" attribute (for which values can also be explicitly
provided) will by default be set equal to the field-name.

The workshop will be held on November 4, 2019, in The Venetian Macao Resort Hotel, Macau, China in the context of the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), one of the largest and highest impact robotics research conferences worldwide.
The workshop will be the first behavior tree-related workshop within the robotics community. We aim to gather all the outstanding researchers interested in BTs to share ideas and lesson learned. For that reason, the workshop format will include invited talks as well as short spotlight presentations followed by interactive sessions.
Behavior Trees is a new powerful tool for task switching and decision making that is receiving an increasing amount of attention in robotics. Recent research is beginning to explore areas such as learning, planning, and control in domains ranging from Micro Air Vehicles to Assembly robotics.
The objectives of this workshop are as follows:
Behavior Trees were developed in the video game industry as a tool to achieve modular, reusable, and flexible behaviors for Non-Player Characters (NPCs), and are now an established tool to the point that BTs are integral parts of game AI textbooks as well as major game engines such as Unity3d, and the Unreal Engine. In the last decade, Behavior Trees have received an increasing amount of attention in robotic as well, with applications in both academia and industry. The main advantages of Behavior Trees with respect to conventional execution architectures, like FSMs, are their ability to combine reactivity with deliberation in a very modular way.
The following list provides a set of topics (keywords) addressed in the workshop.

Hey there! 👋
Welcome to my tiny corner in the ocean which is the web!
My name is Julian "jhx" and I currently live and work on this planet (..still).
I'm deeply interested in IT (...and stuff that has to do with computers).
I also quite enjoy retro computers - or systems from the past in general.
Retro gaming is a great pastime of mine (NES, SNES, GB, N64, PC etc.).
Little old me loves GNU/Linux and BSD. Sometimes I dabble with Windows.
Free Software or FOSS is what I use all the time - and what I prefer!
Yes, I also do some coding for fun. I have a couple of languages that I'm interested in.
Check out my Github page and maybe find something useful!
That's all.. have fun! 😎

Embedded code has a tendency to get messy. More so, I would argue, then code written for a high-level application. Masks and addresses in hexadecimal, strange types defined by obscure libraries, and no classes, can all compound readability issues.
The landscape of an embedded codebase can be vast, obscure, and complicated; And usually by the time you get used to its quirks and learn its style, its time to move on to a different microcontroller with a different library. This makes writing clean and readable code that much more difficult, and that much more important.
This chapter will cover some tools you can use to make your C code more readable. The following concepts will be covered:

Sana Muhammad crossbow death: Ex-husband guilty of murder
A man who shot dead his heavily pregnant ex-wife with a crossbow has been found guilty of murder.
Sana Muhammad was shot through the abdomen by Ramanodge Unmathallegadoo at her home in Ilford, east London, in November 2018.
He hid in a shed in his ex-partner's garden armed with two crossbows, bolts, a knife, duct tape, cable ties and a hammer, the Old Bailey heard.
Mrs Muhammad's son - her sixth child -was delivered by Caesarean section.
Jurors heard Unmathallegadoo plotted the attack - buying two crossbows which were discovered near his ex-wife's home by a neighbour in March 2018.
After they were removed, he replaced the weapons and organised surveillance on the house in Applegarth Drive.
Jurors heard the couple's relationship ended in 2012 and at the time of the attack, Unmathallegadoo was the subject of a court order which banned him from going within 100 metres of his ex's home.
Mrs Muhammad's second husband Imtiaz told the court he was in the garden and thought he was "dreaming" when he saw the defendant step out of the shed with two crossbows.
He shouted to his wife to run as Unmathallegadoo chased him into their home.
"When she got an arrow she just screamed. I was thinking, 'what is happening?', I was screaming for her."
In a victim impact statement he described her as "my soul mate, my best friend, my wife, my companion and my everything and I love her dearly.
"Ram has finished everything. We all feel lost now", he said.

"I lived for my daughter and my grandchildren.
"I now feel alone, there are days I do not want to live."
Unmathallegadoo had denied murder and claimed he went to the house to talk to Mr Muhammad about his daughter's religion.
He told police Mr Muhammad was his target but that his ex-wife got in the way.
But the prosecution said Unmathallegadoo had wanted to kill the couple and their unborn child.
The court heard Unmathallegadoo's children tried to take the crossbow from him.
Susan Krikler, from the CPS, said: "This was a cold-blooded and calculated execution.
"This devastating attack has left six children without their mother."
Unmathallegadoo trial in April was discharged after a juror raised an issue about the defendant's mental health despite the judge asking the jury not to speculate on the matter.
