Let's think again about the grading problem that we solved in Chapter 13. In solving that
problem, we needed to store and process a collection of objects representing different
types of students. These objects were of one of two types related by inheritance, with the
possibility of more types being added later. Our first solution, in §13.3.1/239, used pointers
to let us store a mixed collection of objects. Each of these pointers might point to a
Core
object, or to an object of a type derived from Core
. User code was responsible for
allocating the objects dynamically, and for remembering to free them. The program was
cluttered with details related to managing the pointers, and was generally tricky.
The problem is that a pointer is a primitive, low-level data structure. Programming with pointers is notoriously error prone. Many of the problems with pointers arise because pointers are independent of the objects to which they point, leading to pitfalls:
In §13.5/247, we solved the grading problem again, this time using the Student_info
handle class. Because this class managed the pointers, our users' code dealt with
Student_info
objects, rather than with pointers. However, the Student_info
class
was intimately tied to the Core
hierarchy: It contained operations that mirrored those in
the public interface of the Core
classes.
What we want to do now is to separate these abstractions. We'll still use
Student_info
to provide the interface, but it will rely on another class to manage the
"handle." That is, this other class will manage the pointers to the implementation objects.
The behavior of this new type can and will be independent of the type of the objects to
which the handle can be attached.
Because we want our class to be independent of the type of object that it manages, we
already know that our class must be a template. Because we want it to encapsulate the
handle behavior, we will call it Handle
. The properties that our class will provide are:
Handle
is a value that refers to an object.Handle
object.Handle
object to determine whether it is bound to another object.Handle
to trigger polymorphic behavior when it points to an object of a
class that belongs to an inheritance hierarchy. That is, if we call a virtual
function
through our class, we want the implementation to choose the function to run dynamically,
just as if we'd called the function through a real pointer.Our Handle
will have a restricted interface: Once you attach a Handle
to an object, the
Handle
class will take over memory management for that object. Users should attach
only one Handle
to any object, after which they should not access the object directly
through a pointer; all access should be through the Handle
. These restrictions will allow
Handle
s to avoid the problems inherent in built-in pointers. When we copy a Handle
object, we'll make a new copy of the object, so that each Handle
points to its own copy.
When we destroy a Handle
, it will destroy the associated object, and doing so will be the
only straightforward way to free the object. We'll allow users to create unbound
Handles
, but we will throw an exception if the user attempts to access the object to which
an unbound Handle
refers (or, more accurately, doesn't refer). Users who want to avoid
the exception can test to see whether the Handle
is bound.
These properties are like the ones that we implemented in the Student_info
class.
The Student_info
copy constructor and assignment operator called clone
to copy the
associated Core
object. The Student_info
destructor destroyed the Core
object as
well. The operations that used the underlying object checked before doing so to ensure
that the Student_info
was bound to a real object. What we want is a class that encapsulates
this behavior, but that we can use to manage an object of any type:
template <class T> class Handle { public: Handle(): p(0) { } Handle(const Handle& s): p(0) { if (s.p) p = s.p->clone(); } Handle& operator=(const Handle&); ~Handle() { delete p; } Handle(T* t): p(t) { } operator bool() const { return p; } T& operator*() const; T* operator->() const; private: T* p; };
The Handle
class is a template class, so that we can create Handles
that refer to any type.
Each Handle<T>
object holds a pointer to an object; the other operations manage this
pointer. Aside from variable-name changes, the first four functions are identical to their
versions in Student_info
. The default constructor sets the pointer to zero to indicate
that the Handle
is unbound. The copy constructor (conditionally) calls the associated
object's clone
function to create a new copy of the object. The Handle
destructor frees
the object. The assignment operator
, like the copy constructor, (conditionally) calls clone
to create a new copy of the object:
template<class T> Handle<T>& Handle<T>::operator=(const Handle& rhs) { if (&rhs != this) { delete p; p = rhs.p ? rhs.p->clone() : 0; } return *this; }
The assignment operator
, as usual, starts by checking for self-assignment, doing nothing if
the test succeeds. If the test fails, we continue by freeing the object that we had been managing,
and then making a copy of the right-hand object. The statement that does the copy
uses the conditional operator (§3.2.2/45) to decide whether it's safe to call clone
.
If rhs.p
is set, we call rhs.p->clone
and assign the resulting pointer to p
. Otherwise,
we set p
to 0.
Because Handle
models pointer behavior, we need a way to bind the pointer to an
actual object, which we do in the constructor that takes a T*
. That constructor remembers
the pointer that it was given, thus binding the Handle
to the object to which t
points. For
example, if we define
Handle<Core> student(new Grad);
we construct a Handle
object named student that contains a Core*
pointer, which we
initialize to point to the object of type Grad
that we just created:
Finally, we define three operator
functions. The first of these, operator bool()
lets
users test the value of a Handle
in a condition. The operation returns true
if the Handle
is bound to an object, and false
otherwise. The other two define operator*
and
operator->
, which give access to the object bound to the Handle
:
template <class T> T& Handle<T>::operator*() const { if (p) return *p; throw runtime_error("unbound Handle"); } template <class T> T* Handle<T>::operator->() const { if (p) return p; throw runtime_error("unbound Handle"); }
Applying the built-in unary *
operator to a pointer yields the object to which the pointer
points. Here we define our own *
, so that *
of a Handle
object yields the value that
results from applying the built-in *
operator to the pointer member of that Handle
object.
Given our student
object, *student
will yield the result of applying *
to student.p
(assuming we could access the p
member). In other words, the result of *student
will be
a reference to the Grad
object that we created when we initialized student
.
The ->
operator is a bit more complicated. Superficially, ->
looks like a binary operator,
but in fact it behaves differently from ordinary binary operators. Like the scope or
dot operators, the ->
operator is used to access a member whose name appears in its right
operand from an object named by its left operand. Because names are not expressions, we
have no direct access to the name that our user requested. Instead, the language requires
that we define ->
to return a value that can be treated as a pointer. When we define
operator->
, we are saying that if x
is a value of type that defines operator->
then
x->y
is equivalent to
(x.operator->())->y
In this case, operator->
returns the pointer that its object holds. So for student
,
student->y
is equivalent to
(student.operator->())->y
which, because of the way we defined operator->
, is equivalent to
student.p->y
(ignoring the fact that protection would not ordinarily allow us to access student.p
directly). Thus, the ->
operator has the effect of forwarding calls made through a Handle
object to the underlying pointer that is a member of the Handle
object.
One of our objectives was for Handle
to preserve the polymorphic behavior associated
with built-in pointers. Having seen the definitions of operator*
and operator->
,
we can see that we have reached our goal. These operations yield either a reference or a
pointer, through which we obtain dynamic binding. For example, if we execute student->grade()
,
we're calling grade
through the p
pointer inside student
. The
particular version of grade
that is run depends on the type of the object to which p
points. Assuming that student
still points to the Grad
object with which it was initialized,
this call would be to Grad::grade
. Similarly, because operator*
yields a reference,
if we evaluate (*student).grade()
, then we are calling grade
through a reference,
and so the implementation will decide which particular function to call at run time.
We could use Handle
s to rewrite the pointer-based grading program from §13.3.1/241:
int main() { vector< Handle<Core> > students; // changed type Handle<Core> record; // changed type char ch; string::size_type maxlen = 0; // read and store the data while (cin >> ch) { if (ch == 'U') record = new Core; // allocate a Core object else record = new Grad; // allocate a Grad object record->read(cin); // Handle<T>::->, then virtual call to read maxlen = max(maxlen, record->name().size()); // Handle<T>::-> students.push_back(record); } // compare must be rewritten to work on const Handle<Core>& sort(students.begin(), students.end(), compare_Core_handles); // write the names and grades for (vector< Handle<Core> >::size_type i = 0; i != students.size(); ++i) { // students[i] is a Handle, which we dereference to call the functions cout << students[i]->name() << string(maxlen + 1 - students[i]->name.size(), ' '); try { double final_grade = students[i]->grade(); streamsize prec = cout.precision(); cout << setprecision(3) << final_grade << setprecision(prec) << endl; } catch (domain_error e) { cout << e.what() << endl; } // no delete statement } return 0; }
This program stores Handle<Core>
objects instead of Core*
objects and so, as we did in
§13.3.1/240, we'll need to write a non-overloaded comparison operation that operates on
const Handle<Core>&
that we can pass to sort
. We leave the implementation as an
exercise, but assume that it is named compare_Core_handles
.
The only other differences are in the output loop. Dereferencing students[i]
yields
a Handle
, which has an operator->
that we use to access the name
and grade
functions
through the underlying Core*
. For example, students[i]->grade()
uses the
overloaded ->
, so it effectively calls students[i].p->grade()
. Because grade
is
virtual
, we'll run the version that is appropriate to the type of the object to which
students[i].p
points. Moreover, because Handle
takes care of memory management
for us, we no longer need to delete
the objects to which the elements of students
refer.
More important, we can also reimplement Student_info
, which can now become a
pure interface class, delegating the work of managing pointers to Handle
:
class Student_info { public: Student_info() { } Student_info(std::istream& is) { read(is); } // no copy, assign, or destructor: they're no longer needed std::istream& read(std::istream&); std::string name() const { if (cp) return cp->name(); else throw runtime_error("uninitialized Student"); } double grade() const { if (cp) return cp->grade(); else throw runtime_error("uninitialized Student"); } static bool compare(const Student_info& s1, const Student_info& s2) { return s1.name() < s2.name(); } private: Handle<Core> cp; };
In this version of Student_info
, cp
is a Handle<Core>
rather than a Core*
. Therefore,
we no longer need to implement the copy-control functions, because the Handle
manages the underlying object. The other constructors operate as before. The name
and
grade
functions look the same, but their execution relies on the conversion to bool
,
which is invoked in the test on cp
and in the overloaded operator->
from the Handle
class, which is used to get at the functions on the underlying objects.
To complete our reimplementation, we need to write the read
function:
istream& Student_info::read(istream& is) { char ch; is >> ch; // get record type // allocate new object of the appropriate type // use Handle<T>(T*) to build a Handle<Core> from the pointer to that object // call Handle<T>::operator= to assign the Handle<Core> to the left-hand side if (ch == U') cp = new Core(is); else cp = new Grad(is); return is; }
This code looks like the earlier Student_info::read
function, but its execution is quite
different. Most obviously, the delete
statement is gone, because the assignment to cp
will free the object if appropriate. To understand this code, we need to trace through it
carefully. For example, when we execute new Core(is)
, we get a Core*
object, which
we implicitly convert to a Handle<Core>
using the Handle(T*)
constructor. That
Handle
value is then assigned to cp
using the Handle
assignment operator, which automatically
delete
s the object, if any, to which the Handle
previously referred. This
assignment constructs and destroys an extra copy of the Core
object that we created, a
copy that we will now see how to avoid.

4.2 Object Graph
Mapping discussed in the previous chapter is used to translate data coming from the
database into a bunch of DataObjects. DataObjects
interconnected with each other using relationships form an object graph. Object graph is a
useful abstraction when thinking about interactions between persistent objects in
Cayenne application.
Object Graph Note:
There is no "ObjectGraph" class in Cayenne - this is a
pure logical concept transparent to the user. Other terms describing
the same concept as object graph are "business objects layer", "persistent objects", etc.
Object graph is stored in memory and manipulated by the ObjectStore instance.
|
Object Relationship Note:
While relationships between objects are represented
as ObjRelationship instances in the DataMap, objects themselves implement relationships as
simple List or DataObject properties.
|
Cayenne object graph has the following principal properties that make it useful and easy
to use in the application:
- All operations on the object graph are controllable by the application.
Developers can add/remove/modify objects related to a given object via corresponding
method calls.
- Initial set of objects is obtained by running a select query, or creating new DataObjects.
- Most objects related to the initial objects can be obtained via simple method calls on
initial objects.
- Object identity and uniquing in a certain context.
Cayenne ensures that there will be no more than one object in any given
DataContext that corresponds to a given database row. For instance if an object is
obtained via a relationship method call, and later another object is obtained
via a query interface for the same database row (think same primary key), only
one object will be created in Cayenne. For the later case an object will not be created,
but rather an already existing object will be reused.
- Synchronization with the database.
Object graph changes can be synchronized with the database in a single method call.
This greatly simplifies management of changes and solves transactional issues.
- Discarding changes.
Object graph changes made since last commit can be
discarded using a single method call.

We're not in a great place with VAR, says Chelsea boss Lampard
Frank Lampard believes the Premier League are setting a dangerous precedent with the use of the Video Assistant Referee (VAR) after technology intervened to give Watford a late penalty in Chelsea's 2-1 win at Vicarage Road.
REUTERS: Frank Lampard believes the Premier League are setting a dangerous precedent with the use of the Video Assistant Referee (VAR) after technology intervened to give Watford a late penalty in Chelsea's 2-1 win at Vicarage Road.
Lampard's Chelsea moved up to third in the league with victory on Saturday but they endured some nervy moments in the closing stages after Gerard Deulofeu converted an 80th-minute penalty for the hosts.
Deulofeu went down under slight contact from Chelsea's Jorginho and after initially pointing for a goal kick, referee Anthony Taylor was advised by the VAR to overturn his decision.
"We're not in a great place with it," the Chelsea manager told reporters after the match.
"I know (using screens) is a bit contentious, I know it could mean every fan might call for it and there might pressure on the referees.
"But if we are overturning decisions because one referee somewhere else thinks it was more of a penalty than the referee on the pitch, then I think we are in a really dangerous place. You're going to be tossing a coin every week."
At the start of the season, the Premier League decided that it would only use technology for "clear and obvious" errors by on-field referees.
Not a single penalty or red card was given by VAR in the opening nine rounds of the competition, but last weekend it made headlines by overturning five key decisions.
Lampard feels there has been a change in policy despite receiving guidance at a meeting earlier this week.
"We spoke a lot about it and the absolute consensus from managers, from referees and from the Premier League was that decisions were not going to get overturned unless they were absolutely clear and obvious or VAR saw something that the referee on the pitch didn't see," he added.
"(In Jorginho's case) it didn't, it nowhere near shows that."

GO Reviewed by Jamie Peck
Rating: ***1/2 (out of ****) Columbia / 1:43 / 1999 / R (language, violence, strong drug use, sexuality, glimpses of nudity) Cast: Sarah Polley; Desmond Askew; Jay Mohr; Scott Wolf;Taye Diggs; William Fichtner; J.E. Freeman; Katie Holmes; Timothy Olyphant; Jane Krakowski; Breckin Meyer; James Duval Director: Doug Liman Screenplay: John August
The emphatic title of "Go" alternates as a well-deserved, one-word recommendation of the movie itself: Don't dawdle, don't deliberate, don't protest, just _go_. It also functions as a well-deserved, one-word summary of what happens in the movie: The characters here are constantly _on_ the go, outrunning disgruntled junkies, angry strip club thugs or their own mistakes. Slap the double-meanings together and you've got one seriously wild ride. To pass "Go" would be to deny yourself the rush of watching fine filmmaking, a truly unpredictable storyline and spirited acting come together in a fully satisfying whole.
A rush of a different kind accompanies the on-screen action, which begins with a Ecstasy deal gone horribly awry and paves the way for trips - literal and figurative - into territory seedier still. A snowball effect of sorts starts in "Go"'s opening scenes, as strapped-for-cash supermarket clerk Ronna (Sarah Polley) agrees to take the shift of British co-worker Simon (Desmond Askew) so he can travel to Las Vegas with his mates and she can hopefully nab enough cash to avoid being evicted from her Los Angeles pad. How convenient, then, that she stumbles into an opportunity to make some extracurricular dough via dabbling in the drug trade.
With a breakneck pace and fine attention to detail, all this is nearly perfectly realized - and only the first in a series of three separate but interlocking "chapters" cooked up by debut screenwriter John August. Bravo to him for keeping momentum dizzily spinning throughout "Go," even if the influence of Quentin Tarantino is fairly obvious in narrative structure, a key soundtrack selection and same scenes shown through several different points-of-view. Could this film have been made without "Pulp Fiction" or "Reservoir Dogs"? Maybe not. Does that negate its intoxicating good-time vibe? Definitely not.
Besides, to call "Go" totally Tarantino overlooks its original energy, style and tone. These assets spark the remaining pair of vignettes, although they aren't quite up to the challenge of topping Ronna's hilariously chaotic plight (though the finale comes close). In the middle section, the focus is on Simon and company, as they recklessly tear through Sin City and get a nudie bar crew on their bad sides. Then, a couple of soap stars (Jay Mohr and Scott Wolf), significant role-players in Ronna's quest for excess, spend a bizarre Christmas dinner with a strange cop (William Fichtner) and his stranger wife (Jane Krakowski).
That last bit provides "Go"'s biggest laugh, as Fichtner's understated performance successfully compliments his unforeseeable ulterior motives. Other MVPs that shine in an already supremely polished cast: Polley, unfazed and quite the entrepenuer; Katie Holmes as her best bud, cutely nervous and caustic when issued by Polley as collateral to a dealer; Timothy Olyphant as the dealer, his dangerous profession and demeanor hiding the fact that he's a pretty OK guy; Taye Diggs as a suave, meditative high-roller; and the always engaging Breckin Meyer, delightfully over-the-top as a crude homeboy-wannabe.
Director Doug Liman went the same route in "Swingers," combining colorful people, snappy dialogue and a jazzy locale, but "Go" goes his freshman feature a few better by upping both dramatic urgency and production values. Most of the plot threads, for example, end up congregating in a place that would have been way out of "Swingers"' budget - a seductively glowing, techno-pumping warehouse rave. It's an ironic setting to bring everything in "Go" together, because this movie deserves some raves of its own.

A Nack-Oriented Reliable Multicast (NORM) convergence layer. The NORM protocol is designed to provide end-to-end reliable transport of bulk data objects or streams over generic IP multicast routing and forwarding services. NORM uses a selective, negative acknowledgement (NACK) mechanism for transport reliability and offers additional protocol mechanisms to conduct reliable multicast sessions with limited "a priori" coordination among senders and receivers. A congestion control scheme is specified to allow the NORM protocol fairly share available network bandwidth with other transport protocols such as Transmission Control Protocol (TCP).
It is capable of operating with both reciprocal multicast routing among senders and receivers and with asymmetric connectivity (possibly a unicast return path) from the senders to receivers. The protocol offers a number of features to allow different types of applications or possibly other higher level transport protocols to utilize its service in different ways. The protocol leverages the use of FEC-based repair and other IETF reliable multicast transport (RMT) building blocks in its design. Norm sessions persist across link down/up events in order to take full advantage of the built-up tx cache used to satisfy repair requests.
Common Configurations
---------------------
Here are some basic examples to get you started. The full list of link:w parameters are summarized in the next section.
Assume DTN nodes A, B, and C can communicate over an IP network.
| EID | IPv4 Address |
|---|---|
| dtn://node_a | <IP_ADDRESS> |
| dtn://node_b | <IP_ADDRESS> |
| dtn://node_c | <IP_ADDRESS> |
| dtn://node_d | <IP_ADDRESS> |
Below are the "link add" directives for an always-on unicast link between nodes A and B. Congestion control is enabled (cc) with a maximum tx rate of 230Kbps. "ack" places the remote node in the acking_list; positive acknowledgment is expected after zero of more nack-based repair cycles. "ack" may reduce the number of flush messages.
Node A configuration
link add link_to_b <IP_ADDRESS>:4557 ALWAYSON norm remote_eid=dtn://node_b cc ack rate=230000
Node B configuration
link add link_to_a <IP_ADDRESS>:4557 ALWAYSON norm remote_eid=dtn://node_a cc ack rate=230000
For a one-to-many multicast link, use "link add" on the node sourcing data and use "interface add" on the sink nodes. The Node A "acking_list" requests postive acknowledgments from Nodes B and C (after zero or more nack-based repair cycles). Delivery to Node D may not succeeed because it's not in the acking_list. "nodeid" might be needed for senders and/or receivers when nodes are multi-homed.
Node A configuration
link add link_to_bc <IP_ADDRESS>:4558 ALWAYSON norm multicast_interface=eth0 remote_eid=dtn://group cc rate=230000 acking_list=<IP_ADDRESS>,<IP_ADDRESS>
Node B configuration
interface add norm0 norm multicast_interface=eth0 group_addr=<IP_ADDRESS> nodeid=<IP_ADDRESS>
Node C configuration i
interface add norm0 norm multicast_interface=eth0 group_addr=<IP_ADDRESS> nodeid=<IP_ADDRESS>
Node D configuration
interface add norm0 norm multicast_interface=eth0 group_addr=<IP_ADDRESS> nodeid=<IP_ADDRESS>
For a many-to-many multicast link, use "link add" on all the nodes sourcing data. Below, all nodes can send to and receive from the multicast group. Note the acking_list is adjusted accordingly in each directive.
Node A configuration
link add link_to_bc <IP_ADDRESS>:4558 ALWAYSON norm multicast_interface=eth0 remote_eid=dtn://group cc rate=230000 acking_list=<IP_ADDRESS>,<IP_ADDRESS>,<IP_ADDRESS>
Node B configuration
link add link_to_bc <IP_ADDRESS>:4558 ALWAYSON norm multicast_interface=eth0 remote_eid=dtn://group cc rate=230000 acking_list=<IP_ADDRESS>,<IP_ADDRESS>,<IP_ADDRESS>
Node C configuration
link add link_to_bc <IP_ADDRESS>:4558 ALWAYSON norm multicast_interface=eth0 remote_eid=dtn://group cc rate=230000 acking_list=<IP_ADDRESS>,<IP_ADDRESS>,<IP_ADDRESS>
Node D configuration
link add link_to_bc <IP_ADDRESS>:4558 ALWAYSON norm multicast_interface=eth0 remote_eid=dtn://group cc rate=230000 acking_list=<IP_ADDRESS>,<IP_ADDRESS>,<IP_ADDRESS>
Link Parameters
--------------- To add a norm interface in your config file, use:
Syntax: link add name nexthop type norm [arg=val arg2=val2 argN=valN...]
Valid arguments for arg are:
| arg | Possible settings | Default | Comments |
|---|---|---|---|
| cc | true or false | false | Whether NORM congestion control is enabled. |
| rate | number (bps) | 64000 | Rate of NORM link in bits per second (bps). If congestion control is enabled (see cc) this is the maximum achievable rate. |
| nodeid | string (hostname || IPv4 address) | none | Uniquely identify this node on the NORM link with an IPv4 address. (Normally only needed for multi-homed nodes). |
| segment_size | number (bytes) | 1400 | Maximum payload size of NORM sender messages in bytes (not incl. NORM message header fields). |
| local_port | number (port) | 4558 | (NORM interfaces only) Local UDP port to listen on for incoming multicast traffic. |
| remote_addr | number (bytes) | acquired from the "link add" directive | Remote NORM link IP address (not used -- normally acquired from the "link add" directive) |
| remote_port | number (port) | 4557 | Remote NORM link port. (not used -- normally acquired from the "link add" directive) |
| multicast_interface | interface | tbc | The host interface to use when working with multicast groups. |
| group_addr | IP address (IPv4) | tbc | (NORM interfaces only) Multicast IPv4 address to join. For multicast links, the group address is acquired from the "link add" directive. |
| tx_robust_factor | number | 20 | The number of flush messages sent at the end of each transmission. Flush messages are used to prompt receivers to request needed repairs. With "acking_list" or "ack", periodic flush messages cease once positive ack(s) are received. |
| rx_robust_factor | number | 20 | The number of times a receiver will nack for repairs before giving up. |
| tos | number (marking) | 0 | DSCP marking (0-64) for all bundles on a specific link Size of the receive buffer for each NORM link. |
| acking_list | string (comma delimited list) | tbc | (multicast links) A comma separated list of IPv4 addresses (NORM node ids) that must positively ack sender-initiated flush messages (once any nack-based repair process has completed). |
| ack | tbc | tbc | A shorthand way of requesting positive acks from the remote end of unicast links. |
| silent | true or false | false | "silent" receivers do not originate any NORM traffic and must rely on proactive FEC for repairs. |
| ecn | true or false | false | Whether NORM explicit congestion notification support is enabled. Size of the receive buffer for each NORM link. |
| object_size | number (objects) | 0 | Partition large DTN bundles into multiple NORM data objects for transmission. With the default of zero bytes, no object partitioning is performed. Setting object size to a relatively small value, e.g. 50000 bytes, may be useful in some contention based networks (see tx_spacer). This feature is similar in concept to proactive bundle fragmentation or "bundle MTU" (neither yet implemented in DTN2). (see tx_spacer). |
| tx_spacer | number (ms) | 0 | When combined with object_size, tx_spacer may be used to add a constant pause time (ms) between successive NORM data object transmissions. On contention based networks, this pause time may give other nodes a chance to transmit. |
| keepalive_intvl | number (ms) | 5000 | For DTN opportunistic links, keepalive_intvl is the number of miliseconds between successive keepalive packets. Opportunistic links are made unavailable when three remote keepalive packets are missed. In addition, reliable mode links send watermarks at keepalive intervals. |
| fec_buf_size | number (bytes) | 1048576 | The number of bytes allocated for sender calculated FEC segments and repair state. |
| block_size | number (source symbol segments) | 64 | The number of source symbol segments per coding block for the systematic Reed-Solomon FEC code used in the NRL NORM implementation. |
| num_parity | number (parity blocks) | 16 | The maximum number of parity blocks the sender is willing to calculate per coding block. |
| auto_parity | number (messages) | 0 | The number of "auto-parity" messages sent at the end of each coding block. |
| backoff_factor | number (factor) | 0.0 for unicast; 4.0 for multicast links | Used to scale various timeouts during the NACK repair process. |
| group_size | number | 1000 | Group size is advertised to the receiver group where it is used in calculating backoff timers. Due to encoding techniques in the NORM header, 1000 receivers is the smallest value allowed by the NORM protocol. |
| tx_cache_size_max | number (bytes) | 20971520 | Size of the NORM object cache per link. |
| tx_cache_count_min | number (objects) | 8 | At at minimum, this many objects are allowed to be enqueued in the NORM engine regardless of the object sizes. After the tx_cache_count_min value is surpassed, cache size contraints are in effect (see tx_cache_size_max). |
| tx_cache_count_max | number (objects) | 1024 | The maximum number of objects that may be enqueued for transmission with the NORM engine assuming the total size is less that tx_cache_size_max. |
| rx_buf_size | number (bytes) | 300000 | Size of the receive buffer for each NORM link. |

Lean Project Management is the comprehensive adaptation of Lean concepts like Lean construction, Lean manufacturing and Lean thinking into the project management context.
Our experienced H4M Lean associates will help you plan, manage, and maintain your productivity target through standardization and other Lean product management techniques, delivering more value with less waste.
Time is potentially wasted at three discrete points, or levels within project management:
1.Within projects insofar as specific tasks are concerned; but especially at integration points where multiple completed tasks must be coordinated.
2.Between projects as project managers compete for shared resources. Intuitively, managers know that projects compete with one another for resources. Despite this, quite often little is done to understand and control how the execution of one project negatively impacts other projects.
3.Business management processes; specifically, the overall coordination of strategic objectives marketing and product planning, capital allocation and organizational goals with the life cycle and planning for all projects. Management practices used for the initiation, planning, and funding of projects can cause unpredictable delays at literally any point during the life cycle of projects. For example, up-front delays on any number of key project criteria can subsequently cause re-planning and re-work well after project launch.

Lean Project Management is the comprehensive adaptation of Lean concepts like Lean construction, Lean manufacturing and Lean thinking into the project management context.
Our experienced H4M Lean associates will help you plan, manage, and maintain your productivity target through standardization and other Lean product management techniques, delivering more value with less waste.
Time is potentially wasted at three discrete points, or levels within project management:
1.Within projects insofar as specific tasks are concerned; but especially at integration points where multiple completed tasks must be coordinated.
2.Between projects as project managers compete for shared resources. Intuitively, managers know that projects compete with one another for resources. Despite this, quite often little is done to understand and control how the execution of one project negatively impacts other projects.
3.Business management processes; specifically, the overall coordination of strategic objectives marketing and product planning, capital allocation and organizational goals with the life cycle and planning for all projects. Management practices used for the initiation, planning, and funding of projects can cause unpredictable delays at literally any point during the life cycle of projects. For example, up-front delays on any number of key project criteria can subsequently cause re-planning and re-work well after project launch.

FOOLS RUSH IN (1997) A film review by Chuck Dowling Copyright 1997 Chuck Dowling
Fools Rush In (1997) **1/2 out of ***** - Cast: Matthew Perry, Salma Hayek, Jon Tenney, Siobhan Fallon, Jill Clayburgh. Directed by: Andy Tennant. Running Time: 107 minutes.
An odd attempt to make a romantic comedy based upon a one night stand. Sucessful businessman Perry is assigned to a project in Las Vegas. One night, while waiting in line to use the bathroom at a mexican restuarant, he meets Salma Hayek (who by the way is one of the most beautiful actresses working today) and the two end up in bed together that night.
Anyway, cut to three months later. Hayek pops up at Perry's house to tell him that she's pregnant. A quick series of comic misadventures later and the two are married. Now here's where the film lost it's comedic potential, even though it fully understood that potential, gave it a shot, and then immediately threw it aside. After they get married, Hayek starts to get on Perry's nerves, redecorating his home in a complete mexican motif for example.
Now had the film stayed true to itself, having Perry realize that 1) he was a fool, and 2) he rushed into the situation (as the film's very title suggests) therefore exploiting every potential comedic moment possible, "Fools Rush In" could have been a hilarious movie. Instead it just gets sickeningly sappy, dropping the comedy altogether in favor of attempted romantic scenes which aren't believable for a moment. The cast does it's best though, with Jon Tenney as Perry's best friend getting many of the film's best lines, and Hayek plays just about the most attractive pregnant woman I've ever seen. [PG-13]

Scalar Field $ \Omega( \mathbf{r} ) $
A scalar field is a function that outputs a scalar value, given $ n $ independent variables in $ \mathbb{R}^n. $ It assigns a scalar value to every point in space. A nice example of a scalar field is an elevation map as seen on the right. The elevation value, which is a scalar value, depends on the $ x $ and $ y $ coordinate values on the map. Contour lines or colours are usually used to represent the "height" of the function value, as seen in the map. Some other examples of scalar fields are temperature of a room, pressure distribution in a fluid etc.Vector Field $ \mathbf{f}( \mathbf{r} ) $
A vector field is very similar to a scalar field, except that the function outputs a vector, given $ n $ independent variables in $ \mathbb{R}^n. $ It is used to represent vectorial information. For example, the ocean current map on the right is an example of a vector field that depends on the $ x $ and $ y $ coordinates. At any position, the function assigns a vector that indicates the speed and direction of the ocean current. Other examples of vector fields are electric and magnetic fields.$ \nabla \Omega, $ $ \nabla \cdot \mathbf{f}, $ $ \nabla \times \mathbf{f} $
In 3D Cartesian coordinates, $ \nabla $ is given by $$ \nabla = \mathbf{\hat{i}} \frac {\partial}{\partial x} + \mathbf{\hat{j}} \frac {\partial}{\partial y} + \mathbf{\hat{k}} \frac {\partial}{\partial z}. $$ $ \nabla $ operates on a scalar field $ \Omega $ in one way, that is: $$ \nabla \Omega . $$ This returns a vector field, which is the gradient field of $ \Omega. $ On the other hand, $ \nabla $ can operate on a vector field $ \mathbf{f} $ in two ways, namely $$ \nabla \cdot \mathbf{f} $$ and $$ \nabla \times \mathbf{f}, $$ which give the divergence (scalar) and the curl (vector) of a vector field respectively.In this visualisation suite, we will be placing our focus on the meaning of grad, divergence and curl instead of their mathematical derivations in the following sections, in order to provide a physical intuition to what $ \nabla $ means, both microscopically and macroscopically.
{{sectionTitleLong[1]}}
Gradient Operator: $ \nabla \Omega $
Grad operates on a scalar field $ f(x, y) $ to produce a vector field indicating the magnitude and direction of the steepest gradient at each point.It is easy to remember that grad produces a vector field, because it is necessary for the gradient to have a direction once there is more than one dimension involved. It must act on a scalar field because it doesn't make much sense for a vector field to have a gradient.
Visualisation Guide
The surface shown on the right is a scalar function $ f $ of two independent variables, $ x $ and $ y. $ Note that it is a 2D scalar field — the third dimension is just being used to display the value of the function.Beneath it the gradient of the function $ \nabla f $ is shown. By changing the coefficient $ a, $ the gradient of the function can be increased and decreased in certain directions. There are also several functions to choose from.
The idea extends to three dimensions in the same way. For example, if you were to plot the magnitude of the Sun's gravitational field in 3D space around the Sun, the gradient of this field would give vectors that point to the centre of the Sun at every point.
We can relate $ \Omega $ and $ \nabla \Omega $ by the equation below: $$ \int _A ^B \nabla \Omega \cdot d\mathbf{l} = \Omega_B - \Omega_A $$ From this equation above, we can see that the integral is independent of the path that one takes from A to B, for it is determined by only the values from the parent function $ \Omega_B - \Omega_A. $ This is a generalisation of the Fundamental Theorem of Calculus.
Visualisation Guide
-
On the right, you can see a gradient field and its scalar parent function. Change the value of the parameter $ a, $ and observe the change in $ \nabla \Omega $ and $ \Omega. $
-
Note that as the magnitude of $ a $ increases, the length of the arrows in $ \nabla \Omega $ increases and the contour of the parent function $ \Omega $ becomes steeper as well. Hence, the gradient vector increases in magnitude as well.
-
All gradient fields shown in this suite are conservative. This means that the line integral along the field, $ \int \nabla \Omega \cdot d\mathbf{l} $ is path independent. Move the path of the ball from Point A to Point B along 2 different paths, Path 1 and Path 2.
-
Observe their function values. Note that along the path, the value of $ \Omega $ may be different. However, when the balls reach Point B, their function values are equal.
-
This means that the line integral $ \int _A ^B \nabla \Omega \cdot d\mathbf{l} $ is determined only by the value of $ \Omega $ at the limits, $ \Omega_B - \Omega_A. $
-
There are a few other functions for you to play around with. Click the dropdown menu to find out.
{{sectionTitleLong[2]}}
Divergence Operator: $ \nabla \cdot \mathbf{f} $
Divergence is a vector operator that describes the quantity of a vector field at each point. It is the volume density of outward flux of a vector field at an infinitesimal volume around a point. This leads to another way of understanding divergence:Imagine a point $ (x_A,y_A) $ in the vector field, which has a vector output assigned to it. If $ \nabla \cdot \mathbf{f}(x_A,y_A) \neq 0, $ as we move along an infinitesimal distance parallel to the direction of the vector at the point (that is $ \mathbf{f}(x_A,y_A)), $ there is a change in the magnitude of the output vector, which is the field strength. If divergence is positive, the field strength increases as we move in the direction of the vector at $ (x_A,y_A). $ If divergence is negative, the field strength decreases as we move in the direction of the vector at the point.
Visualisation Guide
-
A vector field is shown on the right. This field has a constant divergence value as indicated.
-
Note that the field does not look like a "source" or "sink". However, the field strength still changes along the x-direction, which indicates a non-zero divergence. As you move along a direction parallel to the vector field at any point, there is a change in the magnitude of the vector field. We can imagine this as if field lines are created or destroyed as we move along.
-
Adjust the slider until the value of divergence is zero. Note that the length of the arrows in the field are constant; there is no creation or destruction of field lines. Hence, this is a divergence-free field.
Flux - the flow of field lines
We often call $ \mathbf{F} \cdot d\mathbf{S} $ the flux of field $ \mathbf{F} $ perpendicular through a surface element $ d\mathbf{S}. $The net flux through any surface $ \mathbf{S} $ is given by the integral: $$ \iint_S \mathbf{F} \cdot d\mathbf{S} $$ By considering a closed surface, the Divergence Theorem relates the net flux to the divergence of the field: $$ {\large\bigcirc}\kern-1.55em\iint_S \mathbf{F} \cdot d\mathbf{S} = \iiint_V \nabla \cdot \mathbf{F} dV $$ An example of the Divergence Theorem is Maxwell's Equation.
Visualisation Guide
In this visualisation, the green line can be thought as taking the side view of the surface element. You may move it by dragging it and rotate it by moving the slider.There are two vectors shown: the black one is the normal of the surface element while the grey one is the field strength at the point.
Note: The flux counter on top right is a scaled flux.
Important: We are using field lines representation here, not vector field.
{{sectionTitleLong[3]}}
The Curl Operator: $ \nabla \times \mathbf{f} $
Curl is a vector operator that describes the infinitesimal rotation of a vector field. It can be seen as the tendency of rotation at a point in the vector field. Curl exists in circulation field such as a vortex.However, curl can still manifest in a non "circulation-looking" vector field like the one on the right. Consider a microscopic point placed in the vector field; if the field strength acting on the point varies at different parts of the point, it creates a tendency for the point to rotate.
This leads to another way of understanding curl:
Imagine travelling over an infinitesimal distance in the direction perpendicular to the vector field at a point. If the field strength changes along this infinitesimal distance travelled, there is a non-zero curl at the point.
Visualisation Guide
-
A vector field is shown on the right. This field has a curl value as indicated.
-
Note that the field does not look like a "circulation". However, as you move along a direction perpendicular to the vector field at any point, there is a change in the magnitude of the vector field. this gives a paddle the tendency to rotate in such a field.
-
Adjust the slider until the value of curl is zero. Note that the length of the arrows in the field are constant; there is no rotational tendency, only translation. Hence, this is a curl-free field.
This is demonstrated in the visualisation on the right, where the components of $ \mathbf {B} \cdot d\mathbf{l} $ as you go around the loop are shown in the plot at the bottom. The contributions are positive if the field and dl are pointing in the same direction.
Visualisation Guide
When there is curl inside the loop then the overall loop integral is non-zero, since on all parts of the loop, the contributions to the integral from the curl source have the same sign; however when the curl source is outside of the loop, then the contributions cancel out and the net integral is zero.This also demonstrates that the curl of a conservative field is zero, since any loop integral in a conservative field is also zero.
You can change the shape of the loop to see that this is true for any type of closed loop.
{{sectionTitleLong[4]}}
The three operations are gradient $ \nabla, $ divergence $ \nabla \cdot $ and curl $ \nabla \times. $ With these operations, we can specify any scalar field or vector field if given enough initial conditions.
To specify a scalar field, we need the value at a point and gradient of the entire space. To specify a vector field, we need the value at a point along with the divergence and curl of the entire space.
There are two theorems that connect these differential operations to integration. They are the Divergence Theorem: $$ {\large\bigcirc}\kern-1.55em\iint_S \mathbf{F} \cdot d\mathbf{S} = \iiint_V \nabla \cdot \mathbf{F} dV $$ and Stoke's Theorem: $$ \oint_{l} \mathbf{A.dl} = \displaystyle \iint_{S} \nabla \times \mathbf {A} \cdot d\mathbf{S} $$ Vector calculus is used extensively in electromagnetic fields, gravitational fields and fluid flow. You may like to visit our electromagnetism visualisation suite on Maxwell's equations. On top of that, there are two interesting applications of the Divergence and Stokes' Theorem where you can explore.

In this document I will type out a plan to outline a course of action to help me achieve my goals. This plan has to aim toward what I consider to be good for me. This means good now, good a week from now and well into the future . My long term goals are to have a stable job in the web development industry.
In order to achieve this I need to obtain a set of human skills that i may not currently possess patience being the main driver of this in my opinion. This is the main thing i need to develop if i am to be successful in my time in EDA . Its something I must remind myself of constantly. Often it's a feeling I have when something doesn't come to me easily. I get a rush of frustration and it makes me liable to abandon the problem. I have to overcome this.
The flip side of this is that I find myself able to be very productive in short bursts 90 mins at a time. I've noticed that if i work like this with a pomodoro and a half hour break in between i'm able to get a great amount of work done in those bursts.
I don't know what to expect of my facilitator because I don't really know what is expected of him.I think of this as a moment to moment issue.If I have a small problem and i cant figure it out i will ask him on slack. If its a big problem I will give him more than a days notice to hold a meeting call with me and hopefully this is acceptable to him.
The main thing i have to tackle is my micro habits .
