List<? extends DataflowInputPort> |
Dataflow.getInputPorts()
Dataflows have a list of input ports.
|
IterationStrategyStack |
Processor.getIterationStrategy()
The iteration strategy is responsible for combining input data events
into jobs which are then queued for execution through the dispatch stack
|
List<? extends Datalink> |
Dataflow.getLinks()
The dataflow is largely defined by the links between processors and other
entities within its scope.
|
List<? extends Merge> |
Dataflow.getMerges()

List<? extends ProcessorOutputPort> |
Processor.getOutputPorts()
Each processor has a list of zero or more output ports.
|
List<? extends DataflowOutputPort> |
Dataflow.getOutputPorts()
Dataflows have a list of output ports.
|
List<? extends Condition> |
Processor.getPreconditionList()
A processor has zero or more preconditions explicitly declared.
|
List<? extends Processor> |
Dataflow.getProcessors()
A Dataflow consists of a set of named Processor instances.
|
| Modifier and Type | Method and Description |
|---|---|
Set<ActivityInputPort> |
Activity.getInputPorts()
An Activity contains a set of named input ports.
|
Set<ActivityOutputPort> |
Activity.getOutputPorts()
An Activity contains a set of named output ports.
|
| Modifier and Type | Method and Description |
|---|---|
List<DispatchLayer<?>> |
DispatchStack.getLayers()
The DispatchStack consists of an ordered list of DispatchLayer instances
where the DispatchLayer at index zero is at the bottom of the stack and
is almost always an invocation layer of some kind (in any working
dispatch stack configuration)
|
Processor |
DispatchStack.getProcessor()
The dispatch stack is contained within a processor, this can be null if
the stack is being used out of this context but layers may be relying on
this link to get information about the processor input ports and their
annotations for various reasons.

Events
CodeIgniter’s Events feature provides a means to tap into and modify the inner workings of the framework without hacking core files. When CodeIgniter runs it follows a specific execution process. There may be instances, however, when you’d like to cause some action to take place at a particular stage in the execution process. For example, you might want to run a script right before your controllers get loaded, or right after, or you might want to trigger one of your own scripts in some other location.
Events work on a publish/subscribe pattern, where an event, is triggered at some point during the script execution. Other scripts can “subscribe” to that event by registering with the Events class to let it know they want to perform an action when that event is triggered.
Enabling Events
Events are always enabled, and are available globally.
Defining an Event
Most events are defined within the app/Config/Events.php file. You can subscribe an action to an event with
the Events
class’ on()
method. The first parameter is the name of the event to subscribe to. The second parameter is
a callable that will be run when that event is triggered:
<?php
use CodeIgniter\Events\Events;
Events::on('pre_system', ['MyClass', 'myFunction']);
In this example, whenever the pre_system
event is executed, an instance of MyClass
is created and the
myFunction()
method is run. Note that the second parameter can be any form of
callable that PHP recognizes:
<?php
// Call a standalone function
Events::on('pre_system', 'some_function');
// Call on an instance method
$user = new User();
Events::on('pre_system', [$user, 'someMethod']);
// Call on a static method
Events::on('pre_system', 'SomeClass::someMethod');
// Use a Closure
Events::on('pre_system', static function (...$params) {
// ...
});
Setting Priorities
Since multiple methods can be subscribed to a single event, you will need a way to define in what order those methods
are called. You can do this by passing a priority value as the third parameter of the on()
method. Lower values
are executed first, with a value of 1 having the highest priority, and there being no limit on the lower values:
<?php
Events::on('post_controller_constructor', 'some_function', 25);
Any subscribers with the same priority will be executed in the order they were defined.
Since v4.2.0, three class constants are defined for your use, that set some helpful ranges on the values. You are not required to use these but you might find they aid readability:
<?php
use CodeIgniter\Events\Events;
Events::PRIORITY_LOW; // 200
Events::PRIORITY_NORMAL; // 100
Events::PRIORITY_HIGH; // 10
Important
The constants EVENT_PRIORITY_LOW
, EVENT_PRIORITY_NORMAL
and EVENT_PRIORITY_HIGH
are deprecated, and the definitions are moved to app/Config/Constants.php
. These will be removed in future releases.
Once sorted, all subscribers are executed in order. If any subscriber returns a boolean false value, then execution of the subscribers will stop.
Publishing your own Events
The Events library makes it simple for you to create events in your own code, also. To use this feature, you would simply
need to call the trigger()
method on the Events class with the name of the event:
<?php
\CodeIgniter\Events\Events::trigger('some_event');
You can pass any number of arguments to the subscribers by adding them as additional parameters. Subscribers will be given the arguments in the same order as defined:
<?php
\CodeIgniter\Events\Events::trigger('some_events', $foo, $bar, $baz);
Events::on('some_event', static function ($foo, $bar, $baz) {
// ...
});
Simulating Events
During testing, you might not want the events to actually fire, as sending out hundreds of emails a day is both slow
and counter-productive. You can tell the Events class to only simulate running the events with the simulate()
method.
When true, all events will be skipped over during the trigger method. Everything else will work as normal, though.
<?php
Events::simulate(true);
You can stop simulation by passing false:
<?php
Events::simulate(false);
Event Points
The following is a list of available event points within the CodeIgniter core code:
pre_system Called very early during system execution. Only the benchmark and events class have been loaded at this point. No routing or other processes have happened.
post_controller_constructor Called immediately after your controller is instantiated, but prior to any method calls happening.
post_system Called after the final rendered page is sent to the browser, at the end of system execution after the finalized data is sent to the browser.
email Called after an email sent successfully from
CodeIgniter\Email\Email
. Receives an array of theEmail
class’s properties as a parameter.DBQuery Called after a database query whether successful or not. Receives the
Query
object.migrate Called after a successful migration call to
latest()
orregress()
. Receives the current properties ofMigrationRunner
as well as the name of the method.

Note:
Any information passed through the customer's browser
can potentially be modified by the customer, or even by third parties to
fraudulently alter the transaction data. Therefore all transactional
information should not be passed through the browser in
a way that could potentially be modified (e.g. hidden form fields).
Transaction data should only be accepted once from a browser at the
point of input, and then kept in a way that does not allow others
to modify it (e.g. database, server session, etc.). Any transaction
information displayed to a customer, such as amount, should be passed
only as display information and the actual transactional data should be
retrieved from the secure source at the point of processing the transaction.
Fields like return links back to the order page (AgainLink), titles, and any other non-transactional information are only included here in the example for information purposes. They do not apply to the transaction and do not have be included in production code orders.

From living in a van to beating a record set by Ed Sheeran: This singer's story is incredible
Sydney - Australian pop hit Dance Monkey is topping global charts and has spent a record 16 weeks at number one Down Under, propelling teenager Toni Watson from busking obscurity to instant fame.
Just months ago the 19-year-old, known by the stage name Tones and I, was living in a van and singing on the street in the coastal town of Byron Bay, south of Brisbane.
Now her latest release has reached number one in 18 countries including Britain, France and Germany, as well as at home where it broke the record held by Ed Sheeran's 2017 smash Shape of You, which spent 15 weeks at the top spot.
WATCH THE VIDEO FOR DANCE MONKEY HERE:
Before her debut single Johnny Run Away came out in March, Watson had spent a year playing her keyboard in public, too nervous to speak to passersby between songs.
But while she is now selling out shows worldwide, the singer says she looks back on those days with fondness.
"When I was busking, when I was paying for petrol with silver coins or when I was sneaking into hostels so I could park my van up and sleep in it, I had the best time of my life," she told Nova radio.
Dance Monkey has racked up more than 500 million plays on Spotify and Toni is the first Australian tune to peak at number one on the streaming service's Global Top 50 chart.
It has even begun to infiltrate the tough North American music world - it is number two in Canada and 23 in the US, where it jumped 18 places from the previous week.
Although Watson's rapid rise has been fuelled by online platforms, Dance Monkey relates the challenges she encountered as a busker trying to capture attention from audiences distracted by smartphones and social media.
"People were so used to being able to swipe to see something different to entertain themselves that the patience had diminished," she told triple j radio.
"You have to be quick... get on with the song."
Watson signed with Warner Chappell Music in August and returned to Byron Bay that month to play at a local music festival.
Her midday set drew a crowd of 20 000 people - a record for an opening act - dwarfing anything she ever may have imagined just a year earlier.

seg1d.algorithm.
cluster
(segGroups, segAdder=0.5, nClust=2)[source]¶ Clustering
Clusters segments based on correlation values
Parameters: - segGroupsn x 3 array
[ [ start index, end index, correlation ] ]
- segAdderfloat, optional
0.0 to 1.0 or None If not None, the value that is added to the cluster groups to force a correlation cluster of the highest values
Returns: - n x 3 array
[start segment, end segment, correlation score of segment]
Other Parameters: - nClustint, optional
number of clusters to group data in (Default 2)
If
nClust=0
, returns segGroups
Warns: - Segment Adder value was included in final cluster.
This may mean cluster is poorly defined or Adder is too high. It is removed before being returned. However, it may be a sign of poor clustering settings as the intention of the segment adder is to force clustering of highly similar segments by creating a lower group (therefore, it should not be in the high cluster group).

Activities
The maintainer’s Git time is spent on three activities.
-
Communication (45%)
Mailing list discussions on general design, fielding user questions, diagnosing bug reports; reviewing, commenting on, suggesting alternatives to, and rejecting patches.
-
Integration (50%)
Applying new patches from the contributors while spotting and correcting minor mistakes, shuffling the integration and testing branches, pushing the results out, cutting the releases, and making announcements.
-
Own development (5%)
Scratching my own itch and sending proposed patch series out.
The Policy
The policy on Integration is informally mentioned in "A Note from the maintainer" message, which is periodically posted to this mailing list after each feature release is made.
-
Feature releases are numbered as vX.Y.Z and are meant to contain bugfixes and enhancements in any area, including functionality, performance and usability, without regression.
-
One release cycle for a feature release is expected to last for eight to ten weeks.
-
Maintenance releases are numbered as vX.Y.Z.W and are meant to contain only bugfixes for the corresponding vX.Y.Z feature release and earlier maintenance releases vX.Y.Z.V (V < W).
-
master branch is used to prepare for the next feature release. In other words, at some point, the tip of master branch is tagged with vX.Y.Z.
-
maint branch is used to prepare for the next maintenance release. After the feature release vX.Y.Z is made, the tip of maint branch is set to that release, and bugfixes will accumulate on the branch, and at some point, the tip of the branch is tagged with vX.Y.Z.1, vX.Y.Z.2, and so on.
-
next branch is used to publish changes (both enhancements and fixes) that (1) have worthwhile goal, (2) are in a fairly good shape suitable for everyday use, (3) but have not yet demonstrated to be regression free. New changes are tested in next before merged to master.
-
pu branch is used to publish other proposed changes that do not yet pass the criteria set for next.
-
The tips of master and maint branches will not be rewound to allow people to build their own customization on top of them. Early in a new development cycle, next is rewound to the tip of master once, but otherwise it will not be rewound until the end of the cycle.
-
Usually master contains all of maint and next contains all of master. pu contains all the topics merged to next, but is rebuilt directly on master.
-
The tip of master is meant to be more stable than any tagged releases, and the users are encouraged to follow it.
-
The next branch is where new action takes place, and the users are encouraged to test it so that regressions and bugs are found before new topics are merged to master.
A Typical Git Day
A typical Git day for the maintainer implements the above policy by doing the following:
-
Scan mailing list. Respond with review comments, suggestions etc. Kibitz. Collect potentially usable patches from the mailing list. Patches about a single topic go to one mailbox (I read my mail in Gnus, and type \C-o to save/append messages in files in mbox format).
-
Write his own patches to address issues raised on the list but nobody has stepped up solving. Send it out just like other contributors do, and pick them up just like patches from other contributors (see above).
-
Review the patches in the saved mailboxes. Edit proposed log message for typofixes and clarifications, and add Acks collected from the list. Edit patch to incorporate "Oops, that should have been like this" fixes from the discussion.
-
Classify the collected patches and handle master and maint updates:
-
Obviously correct fixes that pertain to the tip of maint are directly applied to maint.
-
Obviously correct fixes that pertain to the tip of master are directly applied to master.
-
Other topics are not handled in this step.
This step is done with "git am".
$ git checkout master ;# or "git checkout maint" $ git am -sc3 mailbox $ make test
In practice, almost no patch directly goes to 'master' or 'maint'.
-
Review the last issue of "What’s cooking" message, review the topics ready for merging (topic→master and topic→maint). Use "Meta/cook -w" script (where Meta/ contains a checkout of the todo branch) to aid this step.
And perform the merge. Use "Meta/Reintegrate -e" script (see later) to aid this step.
$ Meta/cook -w last-issue-of-whats-cooking.mbox
$ git checkout master ;# or "git checkout maint" $ echo ai/topic | Meta/Reintegrate -e ;# "git merge ai/topic" $ git log -p ORIG_HEAD.. ;# final review $ git diff ORIG_HEAD.. ;# final review $ make test ;# final review
-
Handle the remaining patches:
-
Anything unobvious that is applicable to master (in other words, does not depend on anything that is still in next and not in master) is applied to a new topic branch that is forked from the tip of master. This includes both enhancements and unobvious fixes to master. A topic branch is named as ai/topic where "ai" is two-letter string named after author’s initial and "topic" is a descriptive name of the topic (in other words, "what’s the series is about").
-
An unobvious fix meant for maint is applied to a new topic branch that is forked from the tip of maint. The topic is named as ai/maint-topic.
-
Changes that pertain to an existing topic are applied to the branch, but:
-
obviously correct ones are applied first;
-
questionable ones are discarded or applied to near the tip;
-
Replacement patches to an existing topic are accepted only for commits not in next.
The above except the "replacement" are all done with:
$ git checkout ai/topic ;# or "git checkout -b ai/topic master" $ git am -sc3 mailbox
while patch replacement is often done by:
$ git format-patch ai/topic~$n..ai/topic ;# export existing
then replace some parts with the new patch, and reapplying:
$ git checkout ai/topic $ git reset --hard ai/topic~$n $ git am -sc3 -s 000*.txt
The full test suite is always run for 'maint' and 'master' after patch application; for topic branches the tests are run as time permits.
-
Merge maint to master as needed:
$ git checkout master $ git merge maint $ make test
-
Merge master to next as needed:
$ git checkout next $ git merge master $ make test
-
Review the last issue of "What’s cooking" again and see if topics that are ready to be merged to next are still in good shape (e.g. has there any new issue identified on the list with the series?)
-
Prepare jch branch, which is used to represent somewhere between master and pu and often is slightly ahead of next.
$ Meta/Reintegrate master..pu >Meta/redo-jch.sh
The result is a script that lists topics to be merged in order to rebuild 'pu' as the input to Meta/Reintegrate script. Remove later topics that should not be in 'jch' yet. Add a line that consists of '### match next' before the name of the first topic in the output that should be in 'jch' but not in 'next' yet.
-
Now we are ready to start merging topics to next. For each branch whose tip is not merged to next, one of three things can happen:
-
The commits are all next-worthy; merge the topic to next;
-
The new parts are of mixed quality, but earlier ones are next-worthy; merge the early parts to next;
-
Nothing is next-worthy; do not do anything.
This step is aided with Meta/redo-jch.sh script created earlier. If a topic that was already in 'next' gained a patch, the script would list it as "ai/topic~1". To include the new patch to the updated 'next', drop the "~1" part; to keep it excluded, do not touch the line. If a topic that was not in 'next' should be merged to 'next', add it at the end of the list. Then:
$ git checkout -B jch master $ Meta/redo-jch.sh -c1
to rebuild the 'jch' branch from scratch. "-c1" tells the script to stop merging at the first line that begins with '###' (i.e. the "### match next" line you added earlier).
At this point, build-test the result. It may reveal semantic conflicts (e.g. a topic renamed a variable, another added a new reference to the variable under its old name), in which case prepare an appropriate merge-fix first (see appendix), and rebuild the 'jch' branch from scratch, starting at the tip of 'master'.
Then do the same to 'next'
$ git checkout next $ sh Meta/redo-jch.sh -c1 -e
The "-e" option allows the merge message that comes from the history of the topic and the comments in the "What's cooking" to be edited. The resulting tree should match 'jch' as the same set of topics are merged on 'master'; otherwise there is a mismerge. Investigate why and do not proceed until the mismerge is found and rectified.
$ git diff jch next
When all is well, clean up the redo-jch.sh script with
$ sh Meta/redo-jch.sh -u
This removes topics listed in the script that have already been merged to 'master'. This may lose '### match next' marker; add it again to the appropriate place when it happens.
-
Rebuild pu.
$ Meta/Reintegrate master..pu >Meta/redo-pu.sh
Edit the result by adding new topics that are not still in 'pu' in the script. Then
$ git checkout -B pu jch $ sh Meta/redo-pu.sh
When all is well, clean up the redo-pu.sh script with
$ sh Meta/redo-pu.sh -u
Double check by running
$ git branch --no-merged pu
to see there is no unexpected leftover topics.
At this point, build-test the result for semantic conflicts, and if there are, prepare an appropriate merge-fix first (see appendix), and rebuild the 'pu' branch from scratch, starting at the tip of 'jch'.
-
Update "What’s cooking" message to review the updates to existing topics, newly added topics and graduated topics.
This step is helped with Meta/cook script.
$ Meta/cook
This script inspects the history between master..pu, finds tips of topic branches, compares what it found with the current contents in Meta/whats-cooking.txt, and updates that file. Topics not listed in the file but are found in master..pu are added to the "New topics" section, topics listed in the file that are no longer found in master..pu are moved to the "Graduated to master" section, and topics whose commits changed their states (e.g. used to be only in 'pu', now merged to 'next') are updated with change markers "<<" and ">>".
Look for lines enclosed in "<<" and ">>"; they hold contents from old file that are replaced by this integration round. After verifying them, remove the old part. Review the description for each topic and update its doneness and plan as needed. To review the updated plan, run
$ Meta/cook -w
which will pick up comments given to the topics, such as "Will merge to 'next'", etc. (see Meta/cook script to learn what kind of phrases are supported).
-
Compile, test and install all four (five) integration branches; Meta/Dothem script may aid this step.
-
Format documentation if the master branch was updated; Meta/dodoc.sh script may aid this step.
-
Push the integration branches out to public places; Meta/pushall script may aid this step.
Observations
Some observations to be made.
-
Each topic is tested individually, and also together with other topics cooking first in pu, then in jch and then in next. Until it matures, no part of it is merged to master.
-
A topic already in next can get fixes while still in next. Such a topic will have many merges to next (in other words, "git log --first-parent next" will show many "Merge branch ai/topic to next" for the same topic.
-
An unobvious fix for maint is cooked in next and then merged to master to make extra sure it is Ok and then merged to maint.
-
Even when next becomes empty (in other words, all topics prove stable and are merged to master and "git diff master next" shows empty), it has tons of merge commits that will never be in master.
-
In principle, "git log --first-parent master..next" should show nothing but merges (in practice, there are fixup commits and reverts that are not merges).
-
Commits near the tip of a topic branch that are not in next are fair game to be discarded, replaced or rewritten. Commits already merged to next will not be.
-
Being in the next branch is not a guarantee for a topic to be included in the next feature release. Being in the master branch typically is.
Appendix
Preparing a "merge-fix"
A merge of two topics may not textually conflict but still have conflict at the semantic level. A classic example is for one topic to rename an variable and all its uses, while another topic adds a new use of the variable under its old name. When these two topics are merged together, the reference to the variable newly added by the latter topic will still use the old name in the result.
The Meta/Reintegrate script that is used by redo-jch and redo-pu scripts implements a crude but usable way to work this issue around. When the script merges branch $X, it checks if "refs/merge-fix/$X" exists, and if so, the effect of it is squashed into the result of the mechanical merge. In other words,
$ echo $X | Meta/Reintegrate
is roughly equivalent to this sequence:
$ git merge --rerere-autoupdate $X
$ git commit
$ git cherry-pick -n refs/merge-fix/$X
$ git commit --amend
The goal of this "prepare a merge-fix" step is to come up with a commit that can be squashed into a result of mechanical merge to correct semantic conflicts.
After finding that the result of merging branch "ai/topic" to an integration branch had such a semantic conflict, say pu~4, check the problematic merge out on a detached HEAD, edit the working tree to fix the semantic conflict, and make a separate commit to record the fix-up:
$ git checkout pu~4
$ git show -s --pretty=%s ;# double check
Merge branch 'ai/topic' to pu
$ edit
$ git commit -m 'merge-fix/ai/topic' -a
Then make a reference "refs/merge-fix/ai/topic" to point at this result:
$ git update-ref refs/merge-fix/ai/topic HEAD
Then double check the result by asking Meta/Reintegrate to redo the merge:
$ git checkout pu~5 ;# the parent of the problem merge
$ echo ai/topic | Meta/Reintegrate
$ git diff pu~4
This time, because you prepared refs/merge-fix/ai/topic, the resulting merge should have been tweaked to include the fix for the semantic conflict.
Note that this assumes that the order in which conflicting branches are merged does not change. If the reason why merging ai/topic branch needs this merge-fix is because another branch merged earlier to the integration branch changed the underlying assumption ai/topic branch made (e.g. ai/topic branch added a site to refer to a variable, while the other branch renamed that variable and adjusted existing use sites), and if you changed redo-jch (or redo-pu) script to merge ai/topic branch before the other branch, then the above merge-fix should not be applied while merging ai/topic, but should instead be applied while merging the other branch. You would need to move the fix to apply to the other branch, perhaps like this:
$ mf=refs/merge-fix
$ git update-ref $mf/$the_other_branch $mf/ai/topic
$ git update-ref -d $mf/ai/topic

The TJC compiler could benefit from
additional work in the following areas, sorted by priority.
Inline Additional Commands
Quite a few Tcl commands that are suitable for inlining have not had
inline support added to TJC. Commands that should be inlined include
the following:
- append
(done)
- global
(done)
- incr
(done)
- info exists
- lappend (done)
- lindex
(done)
- list
(done)
- llength
(done)
- lrange
- lset
- regexp
- regsub
- set
(done)
- string index (done)
- string length (done)
- string compare (done)
- string equal (done)
- string range (done)
Inlined Integer Expr Operations
It is very common for a math expression to deal only with integer
values. Tcl's expr command is written in such a way that either double
or integer values can be used in an expression at any time. The actual
type used for calculations changes depending on the type of the
operands. The compiled expr implementation in TJC could be improved so
that it would be possible to determine what types were being used at
each stage of a calculation and emit inline code for the case of an
integer operation. Additional testing is needed to determine how much
this could speed up math operations and if the performance gain would
be worth the effort required.
For example, the following Tcl code:
expr {$a == 0}
Would be compiled into an inlined expr like the following:
//
Binary operator: $a == 0
TclObject tmp0 = interp.getVar("a", null, 0);
ExprValue tmp1 = TJC.exprGetValue(interp, tmp0);
ExprValue tmp2 = TJC.exprGetValue(interp, 0, null);
TJC.exprBinaryOperator(interp, TJC.EXPR_OP_EQUAL, tmp1, tmp2);
//
End Binary operator: ==
boolean tmp3 = tmp1.getBooleanValue(interp);
TJC.exprReleaseValue(interp, tmp1);
The above code works as expected, but it could be further optimized.
For example, the
exprBinaryOperator() method
must always check the type of each argument to the operator. In the Tcl
expr command above, the type of the constant 0 is always the integer
type. The compiler is currently unable to take advantage of this
information to emit optimized logic when the type of the right hand
operator is known. When used with integer arguments, the binary
operators
* + - < > <=
>= == != eq ne & ^ and | a Tcl expr operator can be
represented by a single Java statement. An improved TJC compiler could
emit optimized code for the code above, like the following:
//
Binary operator: $a == 0
TclObject tmp0 = interp.getVar("a", null, 0);
ExprValue tmp1 = TJC.exprGetValue(interp, tmp0);
if (tmp1.isIntType()) {
tmp1.setIntValue( tmp1.getIntValue() == 0 );
} else {
ExprValue tmp2 = TJC.exprGetValue(interp, 0, null);
TJC.exprBinaryOperator(interp, TJC.EXPR_OP_EQUAL, tmp1, tmp2);
}
//
End Binary operator: ==
boolean tmp3 = tmp1.getBooleanValue(interp);
TJC.exprReleaseValue(interp, tmp1);
The optimized integer version of this expr command would execute more
quickly because type checking for the right hand operator need not be
done. Also, the operator logic is inlined in the code, which will
execute more quickly than a call to the
exprBinaryOperator()
method.
Shared Constant Table
Currently, each command maintains a separate constant table. For
example,
the string "foo" is saved in a TclObject of type TclString. This
implementation makes access to the constant string "foo" very
efficient. Trouble is, there is no way to share constants across
multiple commands. If a command c1 defines a constant string "foo" and
another command c2 also defines a constant string "foo", then two
instances of a constant TclObject are created for the same string. It
is likely that memory usage could be significantly reduced if commands
were able to share a common constant pool.
Eliminate Unused Interp Result Operations
Consider the following Tcl code:
proc p {} {
set items
[list ONE TWO THREE]
set e [lindex
$items 0]
return $e
}
The proc defined above will set the interp result 5 times, twice for
the
set command
invocations, once for the
list
command, once for the
lindex
command, and once for the
return
command. It should be possible to optimize away 4 of these result set
operations. The two calls to the
set
command are not nested commands and they are followed by a return
command, so these result set operations can easily be removed. The two
nested commands can also avoid the interp result set operations by
directly setting the value of the variable instead of the interp
result. The final interp result set operation invoked by the return
command would set the interp result for the whole command and could not
be optimized away.
To illustrate how this would actually work, a portion of the source
code generated for the proc defined above is shown here. This is the
code for the first
set
command that defines the
items
variable in the proc p.
{ // Invoke: set items [...]
TclObject tmp0;
{ // Invoke: list ONE TWO THREE
TclObject tmp1 = TclList.newInstance();
try {
TclList.append(interp, tmp1, const0);
TclList.append(interp, tmp1, const1);
TclList.append(interp, tmp1, const2);
} catch (TclException ex) {
tmp1.release();
throw ex;
}
interp.setResult(tmp1);
} // End Invoke: list
tmp0 = interp.getResult();
tmp0 = setVarScalar(interp, "items", tmp0, 0, varcache1, 1);
interp.setResult(tmp0);
} // End Invoke: set
The code above invokes
interp.setResult()
two times, once for the nested
list command and once for the
set command. Ignoring the
second result set operation and optimizing the first would result in
functionally equivilent code. The following code example shows how the
interp.setResult() operations
could be commented out and replaced with inlined logic that avoids the
unneeded invocations.
{ // Invoke: set items [...]
TclObject tmp0;
{ // Invoke: list ONE TWO THREE
TclObject tmp1 = TclList.newInstance();
try {
TclList.append(interp, tmp1, const0);
TclList.append(interp, tmp1, const1);
TclList.append(interp, tmp1, const2);
} catch (TclException ex) {
tmp1.release();
throw ex;
}
//interp.setResult(tmp1);
tmp0 = tmp1;
} // End Invoke: list
//tmp0 = interp.getResult();
tmp0 = setVarScalar(interp, "items", tmp0, 0, varcache1, 1);
//interp.setResult(tmp0);
} // End Invoke: set
Avoiding invocations of the
interp.setResult() method in
cases where it is not needed will increase performance
of TJC compiled commands. Implementing this feature in TJC will require
addition of logic to detect and handle these situations and addition of
a number of test cases to validate the correctness of the optimized
code.
Testing shows that the following Tcl command:
proc result1 {} {
set sum 0
for {set i 0}
{$i < 1000} {incr i} {
incr sum $i
}
return $sum
}
Executes in about 850 ms when interp result setting is emitted. When
modified to remove unneeded result setting operations, the same code
executes in about 650 ms. These results show that this result set
optimization can improve runtime performance by 25% in some cases.
Local Variable Type Determination
A number of optimizations could be applied if the compiler were able to
tell that a given variable was used only as a single type throughout a
command. For example, a variable that was accessed only as an integer
could be saved in a local variable of type int. Another example would
be a variable that was accessed only as a list. Currently, there is
currently no type determination support in TJC.
Consider the following Tcl for loop:
for {set i 0} {$i < 1000}
{incr i} {
# Do Something
}
Currently, code like the following is emitted. This example is
significantly simplified, the
set
and
incr command
invocations have been replaced by a comment showing where they would be
emitted:
{ // Invoke: for {set i 0} {$i < 1000} {incr i} ...
// Invoke: set i 0
for ( boolean skip = true ; true ; ) {
if ( skip ) {
skip = false;
} else {
// Invoke: incr i
}
// Binary operator: $i < 1000
TclObject tmp1 = getVarScalar(interp, "i", 0, varcache1, 1);
ExprValue tmp2 = TJC.exprGetValue(interp, tmp1);
ExprValue tmp3 = TJC.exprGetValue(interp, 1000, null);
TJC.exprBinaryOperator(interp, TJC.EXPR_OP_LESS, tmp2, tmp3);
// End Binary operator: <
boolean tmp4 = tmp2.getBooleanValue(interp);
TJC.exprReleaseValue(interp, tmp2);
if ( ! tmp4 ) { break; }
// Do Something
}
interp.resetResult();
} // End Invoke: for
If the compiler was able to determine that the loop variable
$i is always used as an
int, then code like the
following could be emitted.
{ // Invoke: for {set i 0} {$i < 1000} {incr i} ...
for ( int
i = 0 ;
true ; i++ ) {
// Binary operator: $i < 1000
ExprValue tmp0 = TJC.exprGetValue(interp, i, null);
ExprValue tmp1 = TJC.exprGetValue(interp, 1000, null);
TJC.exprBinaryOperator(interp, TJC.EXPR_OP_LESS, tmp0, tmp1);
// End Binary operator: <
boolean tmp4 = tmp2.getBooleanValue(interp);
TJC.exprReleaseValue(interp, tmp2);
if ( ! tmp4 ) { break; }
// Do Something
}
interp.resetResult();
} // End Invoke: for
Assuming that inlined int expression optimizations were also
implemented, it should be possible to further simplify this code into
the following:
{ // Invoke: for {set i 0} {$i < 1000} {incr i} ...
for ( int i = 0 ; i < 1000 ; i++ ) {
// Do Something
}
interp.resetResult();
} // End Invoke: for
Loop Invariant Determination
Consider the following Tcl for loop:
set max 1000
for {set i 0} {$i < $max}
{incr i} {
# Do Something
}
At the start of each loop, the expression
{$i < $max} is evaluated by
code like the following:
//
Binary operator: $i < $max
TclObject tmp0 = interp.getVar("i", null, 0);
ExprValue tmp1 = TJC.exprGetValue(interp, tmp0);
TclObject tmp2 = interp.getVar("max", null, 0);
ExprValue tmp3 = TJC.exprGetValue(interp, tmp2);
TJC.exprBinaryOperator(interp, TJC.EXPR_OP_LESS, tmp1, tmp3);
//
End Binary operator: <
boolean tmp4 = tmp1.getBooleanValue(interp);
TJC.exprReleaseValue(interp, tmp1);
if (
! tmp4 ) {
// break out of loop
}
The value of the variable
$max does not change during the
body of the loop, but the compiler does not know about this invariant.
This loop would execute more quickly if the compiler was able to query
the value of
$max and
then extract the integer value contained in the
TclObject once at the start of the loop.
Emit Compact Code
For many simple cases, the compiler could emit significantly smaller
code for operations that appear frequently. Consider the following Tcl
commands:
set i 0
set j 10
set k 100
These three set operations could be emitted as inlined code like the
following:
{ // Invoke: set i 0
TclObject tmp0;
tmp0
= setVarScalar(interp, "i", const0, 0, varcache1, 1);
interp.setResult(tmp0);
} // End Invoke: set
{ // Invoke: set j 10
TclObject tmp1;
tmp1
= setVarScalar(interp, "j", const1, 0, varcache2, 2);
interp.setResult(tmp1);
} // End Invoke: set
{ // Invoke: set k 100
TclObject tmp2;
tmp2
= setVarScalar(interp, "k", const2, 0, varcache3, 3);
interp.setResult(tmp2);
} // End Invoke: set
This inlined code is already very compact,
but it could be further simplified by creating a static method that
invokes these same operations:
public static
void setScalarConstant(Interp interp, String varname, TclObject const,
Var cache, int cacheID) {
TclObject tmp;
tmp = setVarScalar(interp, varname, const, 0, cache, cacheID);
interp.setResult(tmp);
}
This emitted code could then invoke the
setScalarConstant()
method for each instance of the command:
{ // Invoke: set i 0
setScalarConstant(interp,
"i", const0, varcache1, 1);
} // End Invoke: set
{ // Invoke: set j 10
setScalarConstant(interp, "j", const1,
varcache2, 2);
} // End Invoke: set
{ // Invoke: set k 100
setScalarConstant(interp, "k", const2,
varcache3, 3);
} // End Invoke: set
The example above is extremely simplified, but it shows
how the size of emitted Java code can be significantly reduced for many
common cases. At runtime, the hotspot compiler should inline the method
invocation so there should be no decrease in runtime performance. This
change should reduce memory requirements since the emitted class files
will be much smaller. This change should also speed up compile times
since far fewer lines of code are passed to
javac.
Compile Itcl methods
Jacl supports the Itcl object system, but the TJC compiler does not
compile the bodies of Itcl methods. The
itcl::body command as well as
method or proc declarations inside a class declaration should be
supported as container commands.
Compile Time Usage Warnings
Users of the
tjc
executable could find it useful to be able to display warnings and
possible usage errors at compile time. Currently, TJC does not attempt
to report syntax errors or usage issues at compile time. For example,
TJC will not compile math expressions unless they are brace quoted, but
there is no way to have the compiler print a warning when it finds an
expression that is not brace quoted.
Tcl Source Include
Users might find it useful to have a module file OPTIONS flag that
would include the original Tcl source for a proc declaration at the top
of the generated Java source. This feature would make it easier to
compare the original Tcl to the generated source code.
Javac Flags Option
Users might want to compile generated Java source files with special
javac command line options.
Currently, all source code is compiled with the
-g option to support debugging
the generated source. For example, passing the
-O option to some versions of
javac will enable compile time
inlining of certain methods. Some options that users might want to pass
include
-encoding,
-source,
-target, and others.

Transport your tastebuds to a Moroccan souk with this meltingly tender lamb tagine packed with shallots and dates.
Place the lamb in a bowl and add the ground coriander, ground ginger, saffron and one tablespoon of the olive oil. Mix well and leave to marinate in the fridge, covered, for 24 hours.
The next day, heat the remaining olive oil in a heavy-based pan with a lid. Cook the lamb until browned all over (you may need to do this in batches). Remove the lamb from the pan and set aside.
Fry the shallots in the same pan until lightly golden then add the garlic and return the lamb to the pan.
Stir in the plain flour and add the tomato purée and cinnamon stick.
Stir in the lamb stock and bring to the boil. Cover tightly and simmer gently for 1½ hours, or until the lamb is tender.
Add the parsley, coriander, lemon rind, dates and honey, stir well to combine and serve with a bowl of cous cous.

Changes in Xcode 6 Beta 4
22 Jul 2014Xcode 6 Beta 4 brought some important changes related to constantly evolving Swift Language. Below is a compilation of the most important ones.
TOC
Access Control
.by() -> stride()
Unicode String improvements
Revised Declaration Modifiers
Landmarks
Access Control
Access levels
Entities can be:
-
private
Can only be accessed from within the source file where they are defined.
-
internal
Can be accessed anywhere within the target where they are defined.
-
public
Can be accessed from anywhere within the target and from any other context that imports the current target’s module.
Things to remember
-
Frameworks need the public API marked as public
-
Implicitly-synthesized initializers for classes and structs are internal by default
- Generated header
- contains only public declarations for Frameworks
- contains both public and internal declarations for Applications
// An example class in a framework target. public class ListItem: NSObject { public var text: String public var isComplete: Bool // Readable throughout the module, but only writeable from // within this file. private(set) var UUID: NSUUID public init(text: String, completed: Bool, UUID: NSUUID) { self.text = text self.isComplete = completed self.UUID = UUID } func refreshIdentity() { self.UUID = NSUUID() } // Must be public because it overrides a public method // and is itself part of a public type. public override func isEqual(object: AnyObject?) -> Bool { if let item = object as? ListItem { return self.UUID == item.UUID } return false } }
-
Declarations marked private are not exposed to the Objective-C runtime if not otherwise annotated.
- If you need a private method or property to be callable from Objective-C, you have to add
the
@objc
attribute to the declaration explicitly.
- If you need a private method or property to be callable from Objective-C, you have to add
the
Limitations
- Unit tests cannot interact with the classes and methods in an application unless they are marked public (unit test target is not part of the application module)
.by() -> stride()
The .by() method for ranges has been replaced with general stride() functions.
Usage
-
for exlusive ranges:
stride(from: to: by:)
-
for inclusive ranges:
stride(from: through: by:)
Examples
stride(from: x, to: y, by: z) //was: (x..<y).by(z)
stride(from: x, through: y, by: z) //was: (x...y).by(z)
Unicode String improvements
The String
type now implements a grapheme cluster segmentation algorithm to
produce Characters. This means that iteration over complex strings that include combining marks, variation sequences, and regional indicators work properly.
// returns 15
countElements("a\u{1F30D}cafe\u{0301}umbrella\u{FE0E} \u{1F1E9}\u{1F1EA}”)
A for-in
loop over the string produces each human visible character in sequence.
Revised Declaration Modifiers
The @final
, @lazy
, @optional
, and @required
attributes have been converted to declaration modifiers, specified without an @
sign.
-
@final
->final
-
@lazy
->lazy
-
@optional
->optional
-
@required
->required
Landmarks
Finally! Xcode now supports //MARK:
, //TODO:
and //FIXME
landmarks to annotate your code and
lists them in the jump bar.

Meath housing estate fire 'not believed to be suspicious'
by By Digital Desk staffUpdate: A fire in a housing estate in County Meath is not believed to be suspicious.
Four houses have been damaged, two of them extensively at Meadowbank Hill in Ratoath after it broke out at around 4am.
Gardaí believe the blaze started in a van parked in one of the driveways, before it spread to the four houses and another car.
Nobody was injured in the fire.

Gardaí say the fire broke out in a van parked in the driveway of a house at Meadowbank Hill in Ratoath shortly after 4am this morning.
The fire quickly spread to a number of houses and a second car.
Two of the houses were extensively damaged and smoke damage was also caused to two other homes.
Fire services from Ashbourne and Dunshaughlin tackled the blaze and the area was evacuated during the incident.
Nobody was injured.
Gardaí say it is not yet clear how the fire started and a forensic examination will take place later today.

I have worked with Ambalink for close to a year. I write for them articles on almost any topic! You can check me out here. By the way, I used to write content for GainWithNdekere and Njoo too! Want to know what am upto? I usually post updates on twitter here.
Sep 2017 - Oct 2018
Mainly personal projects. Hobbyst kind. Not on a professional level though. I would be so grateful if someone gave me the opportunity to work on a professional level.
July 2018 - present
I haven't yet earned this title yet. I mean, am in the intermediary level. There's still so much to learn. Am not sure am worthy of the title. Maybe my repositories can speak for themselves. You can find them on Ndekere's Github page.
2019 - Present
The school of life
I have learnt to do whatever it takes to get what I want in life. It's been a painful experience. Lessons learnt. I have grown in the process. So, yeah. Its WORTH IT.
2017 - 2021
Africa Nazarene University.
Surprise! Am still a student. I feel though like I graduated a long time ago. Av learnt so much that I can't wait to apply in the marketplace.
2013 - 2016
Kerugoya Boys' High school.
Not much to talk about here. At least I got a good enough grade to Join Campus. Hope am not sounding too sarcastic...

Nokogiri
DESCRIPTION:
Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri’s many features is the ability to search documents via XPath or CSS3 selectors.
XML is like violence - if it doesn’t solve your problems, you are not using enough of it.
FEATURES:
-
XPath support for document searching
-
CSS3 selector support for document searching
-
XML/HTML builder
Nokogiri parses and searches XML/HTML very quickly, and also has correctly implemented CSS3 selector support as well as XPath support.
SUPPORT:
Before filing a bug report, please read our submission guidelines at:
* http://nokogiri.org/tutorials/getting_help.html
The Nokogiri mailing list is available here:
* http://groups.google.com/group/nokogiri-talk
The bug tracker is available here:
* http://github.com/sparklemotion/nokogiri/issues
The IRC channel is #nokogiri on freenode.
SYNOPSIS:
require 'nokogiri' require 'open-uri' # Get a Nokogiri::HTML::Document for the page we’re interested in... doc = Nokogiri::HTML(open('http://www.google.com/search?q=sparklemotion')) # Do funky things with it using Nokogiri::XML::Node methods... #### # Search for nodes by css doc.css('h3.r a').each do |link| puts link.content end #### # Search for nodes by xpath doc.xpath('//h3/a').each do |link| puts link.content end #### # Or mix and match. doc.search('h3.r a.l', '//h3/a').each do |link| puts link.content end
REQUIREMENTS:
-
ruby 1.8 or 1.9
-
libxml2
-
libxml2-dev
-
libxslt
-
libxslt-dev
ENCODING:
Strings are always stored as UTF-8 internally. Methods that return text values will always return UTF-8 encoded strings. Methods that return XML (like to_xml, to_html and inner_html) will return a string encoded like the source document.
WARNING
Some documents declare one particular encoding, but use a different one. So, which encoding should the parser choose?
Remember that data is just a stream of bytes. Only we humans add meaning to that stream. Any particular set of bytes could be valid characters in multiple encodings, so detecting encoding with 100% accuracy is not possible. libxml2 does its best, but it can’t be right 100% of the time.
If you want Nokogiri to handle the document encoding properly, your best bet is to explicitly set the encoding. Here is an example of explicitly setting the encoding to EUC-JP on the parser:
doc = Nokogiri.XML('<foo><bar /><foo>', nil, 'EUC-JP')
INSTALL:
-
sudo gem install nokogiri
Binary packages
Binary packages are available for:
DEVELOPMENT:
Developing on C Ruby (MRI)
Developing Nokogiri requires racc and rexical to generate the parser and tokenizer. To start development, make sure you have `libxml2` and `libxslt` installed.
Then install hoe and rake-compiler:
$ gem install hoe rake-compiler racc rexical minitest
Then run rake:
$ rake
Developing on JRuby
Currently, development with JRuby depends on CRuby being installed. With CRuby, install racc and rexical:
$ gem install racc rexical
Make sure hoe and rake compiler are installed with JRuby:
$ jgem install hoe rake-compiler
Then run rake:
$ jruby -S rake

A title card that precedes Andrew Dominik's first film declares the work to be a dramatization rather than a biography, but it doesn't really lessen the impact Chopper can have on an audience. It's essentially a biopic about notorious Australian bad boy Mark Brandon Read, who earned the nickname "Chopper" by hacking off the toes of his victims (of which there are, reportedly, 19).
Unlike America's infamous nerdy killers, the heavily tattooed Read is as charismatic as they come. When he explains the world really would be a better place without his victims, we believe that just might be the case. The public's fascination with Read doesn't stop with rehashing the grisly details of his crimes, either. Read has written a series of books from prison, and each has become a bestseller. Although Read's exploits are probably a bit exaggerated, make no mistake about it - he's one bad dude.
The film begins in the '70s, where Read (played by Eric Bana) is in the pokey for botching a kidnapping attempt he'd been dreaming of since he was a boy (and all I was concerned with was scoring me some Batman Underoos). It's a maximum-security prison (it still looks like a country club compared to Oz), and Read makes some pretty big enemies while inside. So big, in fact, Read had his own ears sliced off to get himself moved to a different cell block.
Fast-forward to the '80s, where Read is back on the streets, raising all kinds of hell in the seedy underbelly of Melbourne. And he does a lot of really bad things, most of which probably actually happened. It's ghastly, horrible stuff, but Chopper is the rare film in which you can root for a heinous, real-life criminal and not feel like a tool for doing it, making it a bit like John Boorman's The General in some respect. Also appealing is Dominik's decision to neither demonize nor praise Read, leaving that decision to be made by each individual viewer. Dominik fills the film with a number of pretty dazzling visual tricks, as well.
The real star here is Bana, one of Australia's biggest standup comedians He doesn't have much acting experience (he had a small part in The Castle), yet is still able to stick this performance. Think about Ray Romano nailing the lead role in a Ted Bundy biopic to get an idea of how impressive this feat is. Bana is probably just as charismatic as Read, and his deadpan one-liners make the film something special. When Read is shanked by one of his friends, he doesn't roll around in agony, but responds, "What's gotten into you?" When he stabs a foe in the neck, Read doesn't run away, but instead asks, "You all right, mate?"
I think President Dubya would call that Compassionate Callousness.

Lingon is a graphical interface for creating launchd configuration files and controlling them through launchctl for Mac OS X Tiger. (launchd is a system daemon that is used to run scripts/programs automatically, repeatedly or at certain times.) You get all your launchd configuration files listed in a table so you easily can see which are loaded and what they do, and you can also load and unload any easily. If you want to create or edit a launchd configuration file you can do that in Lingon through an assistant or in an easy graphical way (or through an built-in text editor, should you want to).
