This chapter provides general information about writing trigger functions. Trigger functions can be written in most of the available procedural languages, including PL/pgSQL (Chapter 36), PL/Tcl (Chapter 37), PL/Perl (Chapter 38), and PL/Python (Chapter 39). After reading this chapter, you should consult the chapter for your favorite procedural language to find out the language-specific details of writing a trigger in it.
It is also possible to write a trigger function in C, although most people find it easier to use one of the procedural languages. It is not currently possible to write a trigger function in the plain SQL function language.
A trigger is a specification that the database should automatically execute a particular function whenever a certain type of operation is performed. Triggers can be defined to execute either before or after any INSERT, UPDATE, or DELETE operation, either once per modified row, or once per SQL statement. If a trigger event occurs, the trigger's function is called at the appropriate time to handle the event.
The trigger function must be defined before the trigger itself can be created. The trigger function must be declared as a function taking no arguments and returning type trigger. (The trigger function receives its input through a specially-passed TriggerData structure, not in the form of ordinary function arguments.)
Once a suitable trigger function has been created, the trigger is established with CREATE TRIGGER. The same trigger function can be used for multiple triggers.
PostgreSQL offers both per-row triggers and per-statement triggers. With a per-row trigger, the trigger function is invoked once for each row that is affected by the statement that fired the trigger. In contrast, a per-statement trigger is invoked only once when an appropriate statement is executed, regardless of the number of rows affected by that statement. In particular, a statement that affects zero rows will still result in the execution of any applicable per-statement triggers. These two types of triggers are sometimes called row-level triggers and statement-level triggers, respectively.
Triggers are also classified as before triggers and after triggers. Statement-level before triggers naturally fire before the statement starts to do anything, while statement-level after triggers fire at the very end of the statement. Row-level before triggers fire immediately before a particular row is operated on, while row-level after triggers fire at the end of the statement (but before any statement-level after triggers).
Trigger functions invoked by per-statement triggers should always return NULL. Trigger functions invoked by per-row triggers can return a table row (a value of type HeapTuple) to the calling executor, if they choose. A row-level trigger fired before an operation has the following choices:
It can return NULL to skip the operation for the current row. This instructs the executor to not perform the row-level operation that invoked the trigger (the insertion or modification of a particular table row).
For row-level INSERT and UPDATE triggers only, the returned row becomes the row that will be inserted or will replace the row being updated. This allows the trigger function to modify the row being inserted or updated.
A row-level before trigger that does not intend to cause either of these behaviors must be careful to return as its result the same row that was passed in (that is, the NEW row for INSERT and UPDATE triggers, the OLD row for DELETE triggers).
The return value is ignored for row-level triggers fired after an operation, and so they may as well return NULL.
If more than one trigger is defined for the same event on the same relation, the triggers will be fired in alphabetical order by trigger name. In the case of before triggers, the possibly-modified row returned by each trigger becomes the input to the next trigger. If any before trigger returns NULL, the operation is abandoned for that row and subsequent triggers are not fired.
Typically, row before triggers are used for checking or modifying the data that will be inserted or updated. For example, a before trigger might be used to insert the current time into a timestamp column, or to check that two elements of the row are consistent. Row after triggers are most sensibly used to propagate the updates to other tables, or make consistency checks against other tables. The reason for this division of labor is that an after trigger can be certain it is seeing the final value of the row, while a before trigger cannot; there might be other before triggers firing after it. If you have no specific reason to make a trigger before or after, the before case is more efficient, since the information about the operation doesn't have to be saved until end of statement.
If a trigger function executes SQL commands then these commands may fire triggers again. This is known as cascading triggers. There is no direct limitation on the number of cascade levels. It is possible for cascades to cause a recursive invocation of the same trigger; for example, an INSERT trigger might execute a command that inserts an additional row into the same table, causing the INSERT trigger to be fired again. It is the trigger programmer's responsibility to avoid infinite recursion in such scenarios.
When a trigger is being defined, arguments can be specified for it. The purpose of including arguments in the trigger definition is to allow different triggers with similar requirements to call the same function. As an example, there could be a generalized trigger function that takes as its arguments two column names and puts the current user in one and the current time stamp in the other. Properly written, this trigger function would be independent of the specific table it is triggering on. So the same function could be used for INSERT events on any table with suitable columns, to automatically track creation of records in a transaction table for example. It could also be used to track last-update events if defined as an UPDATE trigger.
Each programming language that supports triggers has its own method for making the trigger input data available to the trigger function. This input data includes the type of trigger event (e.g., INSERT or UPDATE) as well as any arguments that were listed in CREATE TRIGGER. For a row-level trigger, the input data also includes the NEW row for INSERT and UPDATE triggers, and/or the OLD row for UPDATE and DELETE triggers. Statement-level triggers do not currently have any way to examine the individual row(s) modified by the statement.
We have table child inherited from table parent.
One could think when inserting|updating into child.col1 that the trigger on parent insert|update will trigger.
That is not the case.
if you want such a behaviour you have to have the trigger on both tables.
"It is also possible to write a trigger function in C, although most people find it easier to use one of the procedural languages."
However, the only immediate example is a trigger based on a C function. Suggest that we add a simple example OR move the example under 36.10 to this chapter. Alternatively, adding a page that links to various examples would be pretty effective.
Consider this example, using PG/psql: You want to monitor price changes, so you create a table to record the barcode, the new price and when it changed:
CREATE TABLE price_change (
apn CHARACTER(15) NOT NULL,
effective TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
UNIQUE (apn, effective)
Next you write a trigger function to insert records as required:
CREATE OR REPLACE FUNCTION insert_price_change() RETURNS trigger AS '
IF tg_op = ''DELETE'' THEN
INSERT INTO price_change(apn, effective, price)
VALUES (old.barcode, CURRENT_TIMESTAMP, NULL);
IF tg_op = ''INSERT'' THEN
changed := TRUE;
changed := new.price IS NULL!= old.price IS NULL OR new.price!= old.price;
IF changed THEN
INSERT INTO price_change(apn, effective, price)
VALUES (new.barcode, CURRENT_TIMESTAMP, new.price);
' LANGUAGE plpgsql;
Finally you create a trigger on the table or tables you wish to monitor:
CREATE TRIGGER insert_price_change AFTER INSERT OR DELETE OR UPDATE ON stock
FOR EACH ROW EXECUTE PROCEDURE insert_price_change();
Row-level before triggers fire immediately before a particular row is operated on, while row-level after triggers fire at the end of the statement (after all rows have been operated on but before any statement-level after triggers).

About Chile in detail
Where is Chile?
Chile, in case, if you are looking on the map under the Coordinates 33 27 S 70 40 W otherwise in South America, in Southern South America, bordering the South Pacific Ocean, between Argentina and Peru.
What is the capital city of Chile?
The capital city of Chile is Santiago.
What is the time in Santiago?
It is 2 hours ahead of Washington, D.C. during Standard Time; Santiago's timezone is UTC-3.
What is the Internet code for Chile?
The Top Level Domain (TLD) for Chile is:.cl
What is the size of Chile?
The territory of Chile is total: 756,102 sq km; land: 743,812 sq km, water: 12,290 sq km.
If we want to describe the size of Chile's territory is somewhat smaller than twice the size of Montana.
If we would like to walk around and discover Chile, we can cover a total distance: 7,801 km.
What is the water coverage of Chile?
We have already mentioned what Chile percentage is covered by water (see below), and this includes a 6,435 km coastline.
What is the climate like in Chile?
Chile's climate is temperate: a desert in the north: the Mediterranean in the central region: cold and damp in the south.
Geographical data of Chile
Chile's elevation; mean elevation: 1,871 m, elevation extremes; lowest point: Pacific Ocean 0 m, highest point: Nevado Ojos del Salado 6,880 m.
Chile's specific geographical details include low coastal mountains, fertile central valley, and the rugged Andes in the east.
Suppose we would like to describe the countries location from a different perspective. In that case, it is safe to say, and easy to read from a map, Chile is the longest north-south trending country in the world, extending across 39 degrees of latitude; strategic location relative to sea lanes between the Atlantic and Pacific Oceans (Strait of Magellan, Beagle Channel, Drake Passage); Atacama Desert – the driest desert in the world – spreads across the northern part of the country; the crater lake of Ojos del Salado is the world's highest lake (at 6,390 m).
Resources and land use of Chile
The country's main mined products are copper, timber, iron ore, nitrates, precious metals, molybdenum, hydropower. The population partly uses the earlier highlighted land territory and partly left in its natural state: agricultural land: 21.1%; arable land 1.7%; permanent crops 0.6%; permanent pasture 18.8%; forest: 21.9%; other: 57% (2011 estimate).
Population data of Chile
The number of inhabitants of Chile is 17,650,114 (July 2016 estimate).
If we examine the proportion of the population distribution, it is safe to say that 90% of the population is located in the middle third of the country around Santiago's capital; the far north (anchored by the Atacama Desert) and the extreme south are relatively underpopulated.
If we look at the proportion of the urbanized and barely populated areas, these are the figures: urban population: 89.5% of the total population (2015).
Most of the population in Chile is concentrated in SANTIAGO (capital) 6.507 million; Valparaiso 907,000; Concepcion 816,000 (2015).
Ethnicity in Chile
According to ethnicity details, the ethnic groups are white and non-indigenous 88.9%, Mapuche 9.1%, Aymara 0.7%, other indigenous groups 1% (includes Rapa Nui, Likan Antai, Quechua, Colla, Diaguita, Kawesqar, Yagan or Yamana), unspecified 0.3% (2012 estimate).
Spoken languages in Chile
The spoken languages in Chile are the following: Spanish 99.5% (official language), English 10.2%, indigenous 1% (includes Mapudungun, Aymara, Quechua, Rapa Nui), other 2.3%, unspecified 0.2%. Note shares sum to more than 100% because some respondents gave more than one answer on the census (2012 estimate).
What are the most important religions in Chile?
According to this, during the general census, researchers examine the churches: Roman Catholic 66.7%, Evangelical or Protestant 16.4%, Jehovah's Witnesses 1%, other 3.4%, none 11.5%, unspecified 1.1% (2012 estimate).
Further population data of Chile
The proportion of gender and age tells a lot about the society as follows 0-14 years: 20.27% (male 1,825,115 / female 1,751,977) 15-24 years: 15.45% (male 1,391,522 / female 1,335,933) 25-54 years: 43.17% (male 3,804,037 / female 3,816,114) 55-64 years: 10.6% (male 880,014 / female 990,969) 65 years and over: 10.51% (male 776,340 / female 1,078,093) (2016 estimate). It also a significant factor in a society the population growth rate, which in the case of Chile is 0.8% (2016 estimate).
The population growth rate is based on two elements, the birth, and the death rate. In Chile the birth rate is 13.7 births / 1,000 population (2016 estimate), the death rate 6.1 deaths / 1,000 population (2016 estimate).
In this day and age in developed societies, the first child borns later compared to the previous centuries and decades, so childbearing is extended. In Chile, the average age of mothers at the first childbirth is N/A.
Although the children's birth is postponed in the best-case scenario, the parents can still see their kids grow as life expectancy also extended. In the case of Chile, these figures are. With the introduction of modern medicine, vaccinations, and the proper hygienic conditions, the infant mortality rate is in a steep decline. The infant mortality statistics in Chile are the following: N/A. Relevant data is the budget of healthcare, which is in the case of this country is 7.8% of GDP (2014).
Economic data of Chile
Suppose we would like to describe a country. We also have to mention its economy; Chile has a market-oriented economy characterized by a high level of foreign trade and a reputation for strong financial institutions and sound policy, giving it the most robust sovereign bond rating in South America. From 2003 through 2013, real growth averaged almost 5% per year, despite the slight contraction in 2009 that resulted from the global financial crisis. Growth slowed to an estimated 1.7% in 2016. A continued drop in copper prices prompted Chile to experieChile deepened its longstanding commitment to trade liberalization with the signing of a free trade agreement with the US, which took effect on 1 January 2004. Chile has 22 trade agreements covering 60 countries, including agreements with the EU, Mercosur.
The Chilean Government has generally followed a countercyclical fiscal policy, accumulating surpluses in sovereign wealth funds during periods of high copper prices and economic growth, and generally allowing deficit spending only during periods of low coIn 2014, President Michelle BACHELET introduced tax reforms aimed at delivering her campaign promise to fight inequality and to provide access to education and health care. The reforms are expected to generate additional tax revenues equal to 3% of Chile's.
GDP is a prominent figure, as all the relevant calculations and statistics are based


Toss those cabers, toss them high
The caber toss is a traditional Scottish sport that involves hurling a caber, which is essentially a large piece of a tree: a caber is a 6 m6~\mbox{m} long, 80 kg80~\mbox{kg} tree trunk. Large strong people hurl these and the goal is to get the caber to land as far away as possible and rotate in the air, so what was the highest part of the trunk initially is actually the part that hits the gound first. See this clip to understand how the caber rotates.
It's HARD to do this. To see how hard, consider a perfectly vertical caber with one end on the ground. You then launch the caber vertically with some speed v0v_0 and give it a rotation. What is the minimum kinetic energy in Joules you need to give the caber so that when it lands the caber is perfectly vertical again, but the OTHER end of the caber hits the ground?
Details and assumptions
 - The acceleration of gravity is 9.8 m/s2-9.8~\mbox{m/s}^2.
 - The caber can be modeled as a uniform rod.

Bloodstalker Eggs are dropped after two Bloodstalkers have mated.
The Bloodstalker Egg takes 2h 56m 27.388s to hatch. It must be in the temperature range of 27 to 30 °C / 81 to 86 °F to successfully hatch, otherwise it will start to lose Health. The female Bloodstalker needs between 18h and 2d before having the capacity to lay eggs again. The incubation time can be reduced by up to 20% if the egg is placed in an Egg Incubator at the ideal temperature.
To be able to hatch the egg, a nearby source of heat such as a Dimetrodon had to be present to incubate it on the spot.
Once hatched, the baby takes in raw meat rather than cooked meat. They also consume blood packs at a much slower rate than meat.
- Bloodstalker Egg is the first to
- have an animated appearance.
- have a different hatching sound effect.

New funding is being provided for projects that support people with Machado Joseph Disease (MJD) in the Northern Territory (NT).
MJD is a hereditary neurodegenerative condition. It is in a 'family' of neurodegenerative diseases that includes Huntington's disease. Previously known as 'Groote Eylandt Syndrome', the effects of MJD have been known to Indigenous people in Arnhem Land in the NT for at least four generations.
The new funding from the Australian Government is worth $460,000 and will be delivered to the MJD Foundation, a charity established in 2008 to improve the quality of life for Indigenous Australians living with MJD in Arnhem Land.
'People living with MJD are wheelchair-bound and reliant on care within 10 to 15 years of the first symptoms, and death occurs between six and 29 years of onset,' said Jenny Macklin, Minister for Families, Housing, Community Services and Indigenous Affairs.
'The Government is investing $180,000 from the Indigenous Remote Service Delivery Special Account to support new projects in Galiwin'ku, Yirrkala, Ngukkur and Groote Eylandt.
'Projects include a women's camp on Groote Eylandt which will bring together women affected by MJD with volunteer health professionals and researchers.
'The MJD Foundation will also work with the Galiwin'ku, Yirrkala and Ngukurr communities to establish activities such as fishing and camping to help bring together families who are affected to share their stories, experiences and health care priorities.'
Minister for Indigenous, Rural and Regional Health, Warren Snowdon, said the Government is also providing more than $280,000 to the MJD Foundation to develop educational resources and conduct workshops across the NT to support families living with MJD.

What is it?
Tailgate hinges are the pivot point on which your truck or SUV's tailgate rotates when being opened and closed. They are found at the bottom of the tailgate, at the back of the vehicle. The hinge will consist of two parts, one connected to the frame of the truck bed and one connected to the tailgate itself. One side will fit into the other and move within it. In this way, it holds the tailgate in place while allowing it to open and close when loading or unloading cargo.
Since they are almost always exposed to the elements, these hinges have a tendency to rust out, bind up, or elongate from use. Dirt or moisture can corrode the hinges or they can simply wear out and become loose from the weight of the tailgate. Loose hinges might make your tailgate or liftgate rattle as you're driving down bumpy roads. In a worst case scenario, a worn tailgate hinge could eventually give way and let the tailgate open up. Then it's time to replace a new one.
How to Replace Tailgate Hinge Inserts?
STEP 1: REMOVING THE TAILGATE CABLES. Pull out on the cable tab and lift the tailgate. Slide the tailgate cable up and off.
STEP 2: REMOVING THE TAILGATE. Lift up the tailgate. Slide the tailgate off the right hinge. Slide the tailgate off the left hinge.
STEP 3: REMOVING THE TAILGATE BUSHINGS
Pry the bushing out form the backside with a flat blade screwdriver.
STEP 4: INSTALLING THE TAILGATE BUSHINGS
Place a little bit of grease into the tailgate slot. Press the bushing into the tailgate.
STEP 5: INSTALLING THE TAILGATE
Grease the hinge. Lift the tailgate cables up. Lift the tailgate up into place. Insert the tailgate into the right hinge first. Insert the tailgate into the left hinge.
STEP 6: INSTALLING THE TAILGATE CABLES
Hook the tailgate cable into its slot. Grease the latch and tailgate

Common mistakes#
1. Creating cells without cell decorator#
The cell decorator names cells deterministically and uniquely based on the name of the functions and its parameters.
It also uses a caching mechanisms that improves performance and guards against duplicated names.
1.a naming cells manually#
Naming cells manually is susceptible to name colisions
in GDS you can't have two cells with the same name.
For example: this code will raise a duplicated cell name ValueError
import gdsfactory as gf
c1 = gf.Component('wg')
c1 << gf.components.straight(length = 5)
c2 = gf.Component('wg')
c2 << gf.components.straight(length = 50)
c3 = gf.Component('waveguides')
wg1 = c3 << c1
wg2 = c3 << c2
wg2.movey(10)
c3
Solution: Use the gf.cell decorator for automatic naming your components.
[1]:
import gdsfactory as gf
@gf.cell
def wg(length: float = 3):

1.b Not naming components with a unique and deterministic name#
In the case of not wrapping the function with cell you will get unique names thanks to the unique identifier uuid.
This name will be different and non-deterministic for different invocations of the script.
However it will be hard for you to know where that cell came from.

Starting with Windows XP, run-down protection is available to kernel-mode drivers. Drivers can use run-down protection to safely access objects in shared system memory that are created and deleted by another kernel-mode driver.
An object is said to be run down if all outstanding accesses of the object are finished and no new requests to access the object will be granted. For example, a shared object might need to be run down so that it can be deleted and replaced with a new object.
The driver that owns the shared object can enable other drivers to acquire and release run-down protection on the object. When run-down protection is in effect, a driver other than the owner can access the object without risk that the owner will delete the object before the access completes. Before the access starts, the accessing driver requests run-down protection on the object. For a long-lived object, this request is nearly always granted. After the access finishes, the accessing driver releases its previously acquired run-down protection on the object.
To start sharing an object, the driver that owns the object calls the ExInitializeRundownProtection routine to initialize run-down protection on the object. After this call, other drivers that access the object can acquire and release run-down protection on the object.
A driver that accesses the shared object calls the ExAcquireRundownProtection routine to request run-down protection on the object. After the access is finished, this driver calls the ExReleaseRundownProtection routine to release run-down protection on the object.
If the owning driver determines that the shared object must be deleted, this driver waits to delete the object until all outstanding accesses of the object are finished.
In preparation to delete the shared object, the owning driver calls the ExWaitForRundownProtectionRelease routine to wait for the object to run down. During this call, ExWaitForRundownProtectionRelease waits for all previously granted instances of run-down protection on the object to be released, but prevents new requests for run-down protection on the object from being granted. After the last protected access finishes and all instances of run-down protection are released, ExWaitForRundownProtectionRelease returns, and the owning driver can safely delete the object.
ExWaitForRundownProtectionRelease blocks the execution of the calling driver thread until all drivers that hold run-down protection on the shared object release this protection. To prevent ExWaitForRundownProtectionRelease from blocking execution for excessively long periods, drivers threads that access the shared object should avoid being suspended while they hold run-down protection on the object. For this reason, accessing drivers should call ExAcquireRundownProtection and ExReleaseRundownProtection within a critical region or guarded region, or while running at IRQL = APC_LEVEL.
Run-down protection is particularly useful for providing access to a shared object that is nearly always available but might occasionally need to be deleted and replaced. Drivers that access data or that call routines in this object must not try to access the object after it is deleted. Otherwise, these invalid accesses might cause unpredictable behavior, data corruption, or even system failure.
For example, an antivirus driver typically stays loaded in memory when the operating system is running. Occasionally, this driver might need to be unloaded and replaced with an updated release of the driver. Other drivers send I/O requests to the antivirus driver to access the data and routines in this driver. Before sending an I/O request, a kernel component, such as a file system filter manager, can acquire run-down protection to guard against premature unloading of the antivirus driver while it handles the I/O request. After the I/O request completes, run-down protection can be released.
Run-down protection does not serialize accesses to a shared object. If two or more accessing drivers can simultaneously hold run-down protection on an object, and accesses to the object must be serialized, some other mechanism, such as a mutual-exclusion lock, must be used to serialize the accesses.
An EX_RUNDOWN_REF structure tracks the status of run-down protection on a shared object. This structure is opaque to drivers. The system-supplied run-down protection routines use this structure to count the number of instances of run-down protection that are currently in effect on the object. These routines also use this structure to track whether the object is run down or is in the process of being run down.
To start sharing an object, the driver that owns the object calls ExInitializeRundownProtection to initialize the EX_RUNDOWN_REF structure associated with the object. After initialization, the owning driver can make this structure available to other drivers that require access to the object. The accessing drivers pass this structure as a parameter to the ExAcquireRundownProtection and ExReleaseRundownProtection calls that acquire and release run-down protection on the object. The owning driver passes this structure as a parameter to the ExWaitForRundownProtectionRelease call that waits for the object to run down so that it can be safely deleted.
Run-down protection is one of several ways to guarantee safe access to a shared object. Another approach is to use a mutual-exclusion software lock. If a driver requires access to an object that is currently locked by another driver, the first driver must wait for the second driver to release the lock. However, acquiring and releasing locks can become a performance bottleneck, and locks can consume large amounts of memory. If used incorrectly, locks might cause drivers that compete for the same shared objects to become deadlocked. Efforts to detect and avoid deadlocks typically require the diversion of substantial computing resources.
In contrast to locks, run-down protection has relatively lightweight processing time and memory requirements. A simple reference count is associated with the object to ensure that deletion of the object is deferred until all outstanding accesses of the object are completed. With this approach, atomic, interlocked hardware instructions can be used instead of mutual-exclusion software locks to guarantee safe access to an object. Calls to acquire and release run-down protection are typically very fast. The benefits of using a lightweight mechanism, such as run-down protection, can be significant for a shared object that has a long life and is shared among many drivers.
Several other run-down protection routines are available, in addition to those that were mentioned previously. These additional routines might used by some drivers.
The ExRundownCompleted routine updates the EX_RUNDOWN_REF structure to indicate that the run down of the associated object has completed.
The ExAcquireRundownProtectionEx and ExReleaseRundownProtectionEx routines are similar to ExAcquireRundownProtection and ExReleaseRundownProtection. These four routines increment or decrement the count of the instances of run-down protection that are in effect on a shared object. Whereas ExAcquireRundownProtection and ExReleaseRundownProtection increment and decrement this count by one, ExAcquireRundownProtectionEx and ExReleaseRundownProtectionEx increment and decrement the count by arbitrary amounts.

## Using audio CDs with NetBSD
There are two ways to handle audio CDs:
 1. Tell the CD drive to play to the headphone or to a soundcard, to which
 CDROMs are usually connected internally. Use programs like
 [cdplay(1)](_URL_
 ['audio/xmcd'](_URL_
 "kscd" from the
 ['multimedia/kdemultimedia3'](_URL_
 package, mixer programs like
 [mixerctl(1)](_URL_
 ['audio/xmix'](_URL_
 ['audio/xmmix'](_URL_
 the Curses based
 ['audio/cam'](_URL_
 or kmix, which is part of
 ['multimedia/kdemultimedia3'](_URL_
 This usually works well on both SCSI and IDE (ATAPI) CDROMs, CDRW and DVD
 drives.
 2. To read ("rip") audio tracks in binary form without going through
 digital-\>analog conversion and back. There are several programs available
 to do this:
 * For most ATAPI, SCSI and several proprietary CDROM drives, the
 ['audio/cdparanoia'](_URL_
 package can be used. With cdparanoia the data can be saved to a file or
 directed to standard output in WAV, AIFF, AIFF-C or raw format. Currently
 the -g option is required by the NetBSD version of cdparanoia. A
 hypothetical example of how to save track 2 as a WAV file is as follows:
 $ cdparanoia -g /dev/rcd0d 2 track-02.wav
 If you want to grab all files from a CD, cdparanoia's batch mode is useful:
 $ cdparanoia -g /dev/rcd0d -B
 * For ATAPI or SCSI CD-ROMs the
 ['audio/cdd'](_URL_
 package can be used. To extract track 2 with cdd, type:
 # cdd -t 2 'pwd'
 This will put a file called 'track-02.cda' in the current directory.
 * For SCSI CD-ROMS the
 ['audio/tosha'](_URL_
 package can be used. To extract track 2 with tosha, you should be able to
 type:
 # tosha -d CD-ROM-device -t 2 -o track-02.cda
 The data can then be post-processed e.g. by encoding it into MP3 streams
 (see [[Creating an MP3 (MPEG layer 3) file from an audio
 CD|guide/rmmedia#create-mpeg3]]) or by writing them to CD-Rs (see [[Using a
 CD-R writer to create audio CDs|guide/rmmedia#cdr-audio]]).
## Creating an MP3 (MPEG layer 3) file from an audio CD
The basic steps in creating an MPEG layer 3 (MP3) file from an audio CD (using
software from the [NetBSD packages
collection](_URL_ are:
 1. Extract (*rip*) the audio data of the CD as shown in
 [[Using audio CDs with NetBSD|guide/rmmedia#cdrom-audio]].
 2. Convert the CD audio format file to WAV format. You only need to perform
 this job if your ripping program (e.g. tosha, cdd) didn't already do the job
 for you!
 * Using the ['audio/sox'](_URL_ package, type:
 $ sox -s -w -c 2 -r 44100 -t cdr track-02.cda track-02.wav
 This will convert 'track-02.cda' in raw CD format to 'track-02.wav' in
 WAV format, using **s**igned 16-bit **w**ords with 2 **c**hannels at a
 sampling **r**ate of 44100kHz.
 3. Encode the WAV file into MP3 format.
 * Using the ['audio/bladeenc'](_URL_ package, type:
 $ bladeenc -128 -QUIT track-02.wav
 This will encode 'track-02.wav' into 'track-02.mp3' in MP3 format, using
 a bit rate if **128**kBit/sec. The documentation for bladeenc describes
 bit-rates in more detail.
 * Using the
 ['audio/lame'](_URL_
 package, type:
 $ lame -p -o -v -V 5 -h track-02.wav track-02.mp3
 You may wish to use a lower quality, depending on your taste and
 hardware.
The resultant MP3 file can be played with any of the
['audio/gqmpeg'](_URL_
['audio/maplay'](_URL_
['audio/mpg123'](_URL_
or
['audio/splay'](_URL_
packages.
## Using a CD-R writer with data CDs
The process of writing a CD consists of two steps: First, a "image" of the data
must be generated, which can then be written to CD-R in a second step.
 1. Reading a pre-existing ISO image
 # dd if=/dev/rcd0a of=filename.iso bs=2k
 Alternatively, you can create a new ISO image yourself:
 2. 2. 2.ating the ISO image
 Put all the data you want to put on CD into one directory. Next you need to
 generate a disk-like ISO image of your data. The image stores the data in
 the same form as they're later put on CD, using the ISO 9660 format. The
 basic ISO9660 format only understands 8+3 filenames (max. eight letters for
 filename, plus three more for an extension). As this is not practical for
 Unix filenames, a so-called "Rockridge Extension" needs to be employed to
 get longer filenames. (A different set of such extension exists in the
 Microsoft world, to get their long filenames right; that's what's known as
 Joliet filesystem).
 The ISO image is created using the mkisofs command, which is part of the
 ['sysutils/cdrtools'](_URL_
 package.
 Example: if you have your data in /usr/tmp/data, you can generate a ISO
 image file in /usr/tmp/data.iso with the following command:
 $ cd /usr/tmp
 $ mkisofs -o data.iso -r data
 Using NETBS000.GZ;1 for data/binary/kernel/netbsd.INSTALL.gz (netbsd.INSTALL_TINY.gz)

 Please see the mkisofs(8) man page for other options like noting publisher
 and preparer. The [Bootable CD ROM
 How-To](_URL_ explains how to generate a
 bootable CD.
 3. Writing the ISO image to CD-R
 When you have the ISO image file, you just need to write it on a CD. This is
 done with the "cdrecord" command from the
 ['sysutils/cdrtools'](_URL_
 package. Insert a blank CD-R, and off we go:
 # cdrecord -v dev=/dev/rcd0d data.iso
 ...
 After starting the command, 'cdrecord' shows you a lot of information about
 your drive, the disk and the image you're about to write. It then does a 10
 seconds countdown, which is your last chance to stop things - type \^C if
 you want to abort. If you don't abort, the process will write the whole
 image to the CD and return with a shell prompt.
 Note that cdrecord(8) works on both SCSI and IDE (ATAPI) drives.
 4. Test
 Mount the just-written CD and test it as you would do with any "normal" CD,
 see [[Reading data CDs with NetBSD

A consistent CSG model is one which is made up of solid objects with no dangling surfaces. In rayshade, it is quite easy to construct inconsistent models, which will usually appear incorrect in the final images. In rayshade, CSG is implemented by maintaining the tree structure of the CSG operations. This tree is traversed, and the operators therein applied, on a per-ray basis. It is therefore difficult to verify the consistency of the model ''on the fly.''
One class of CSG problems occur when surfaces of objects being operated upon coincide. For example, when subtracting a box from another box to make a square cup, the result will be wrong if the tops of the two boxes coincide. To correct this, the inner box should be made slightly taller than the outer box. A related problem that must be avoided occurs when two coincident surfaces are assigned different surface properties.
It may seem that the union operator is unnecessary, since listing two objects together in an aggregate results in an image that appears to be the same. While the result of such a short-cut may appear the same on the exterior, the interior of the resulting object will contain extraneous surfaces. The following example show this quite clearly.
difference box -2 0 -3 2 3 3 union /* change to list; note bad internal surfaces */ sphere 2 1 0 0 sphere 2 -1 0 0 end end rotate 1 0 0 -40 rotate 0 0 1 50
The visual evidence of an inconsistent CSG object varies depending upon the operator being used. When subtracting a consistent object from and inconsistent one, the resulting object will appear to be the union of the two objects, but the shading will be incorrect. It will appear to be inside-out in places, while correct in other places. The inside-out sections indicate the areas where the problems occur. Such problems are often caused by polygons with incorrectly specified normals, or by surfaces that exactly coincide (which appear as partial ''Swiss cheese'' objects).
The following example illustrates an attempt to subtract a sphere from a pyramid defined using an incorrectly facing triangle. Note that the resulting image obviously points to which triangle is reversed.
name pyramid list triangle 1 0 0 0 1 0 0 0 1 triangle 1 0 0 0 0 0 0 1 0 triangle 0 1 0 0 0 0 0 0 1 triangle 0 0 1 1 0 0 0 0 0 /* wrong order */ end difference object pyramid scale 3 3 3 rotate 0 0 1 45 rotate 1 0 0 -30 translate 0 -3.5 0 sphere 2.4 0 0 0 end
By default, cylinders and cones do not have end caps, and thus are not consistent primitives. One must usually add endcaps by listing the cylinder or cone with (correctly-oriented) endcap discs in an aggregate.

3 types of buzzing
Posted on July 27, 2004 by
Why lip buzz or mpc buzz or leadpipe buzz. What is the difference. Besides I heard that a study showed we don't have to buzz.
Many great teachers advocated lip and or mouthpiece buzzing (to certain students).
They are used as exercises and to teach a certain concept. After the idea is understood the buzzing is stopped.
Leadpipe buzzing has more to do with AIR-flow while lip buzzing deals with Strength, range and a close embouchure setting. Mouthpiece buzzing is normally to work on a dynamic embouchure rather than static one. So that your embouchure can always adjust and shift registers as you play.
Strength exercises are short lived so as NOT to impede lip flexibility. AIR exercises are forever.
FWIW we've known since the early 60's that there is a standing wave setup in the tubing of the trumpet. I first read Schilke's report in 73 or 74. The fact that a buzz is not required does not mean that the skill learned doing it is not important.
If you only know how to dogpaddle then you can "say" you know how to swim. I doubt that a dogpaddle would win a swim meet however. Knowledge and skills always pay off.

Model Test and Numerical Simulation for Support Time of Tunnel in Loess
The work presented in this paper focuses on support time for tunnel, which has much effect on stability of tunnel. Based on loess tunnel of Zhengzhou-Xi'an high-speed passenger rail line in China, large scale model test with geometric proportion 1: 20 was applied to study on different support time. Supplemental numerical analysis was carried out to investigate the effect of release ratio of stress which cannot be covered by model test. It is revealed that it is asynchronous change for deformation, strain and stress of surround rock. If the supporting constructs prematurely, internal force of support would be excessive greatly and if the supporting constructs too late, it will bring excessive slack pressure which leads to the plastic zone unfavorable, even tunnel collapse. The reasonable support time can improve self-bearing capability of surrounding rock and reduce the cost. The limited displacements about 17.8 cm for crown and 12.9 for horizontal convergence are gained. The research results can act as reference for similar materials tunnel and underground engineering construction.

Olympus E-1
Single-lens reflex (SLR) cameras with interchangeable lenses are popular with serious amateur and professional photographers. Unfortunately, digital SLR cameras are very susceptible to dust. And if dust particles get inside the camera while you're changing lenses, they can stick to the image sensor and show up as dark spots in every photo you take.Shake It Off
Once dust sneaks into your camera, it will stay there until it is removed. Since digital image sensors are very delicate, some camera manufacturers recommend that shutterbugs bring dirty cameras into a service center for cleaning. As a result, many SLR users are reluctant to change lenses, especially when shooting in windy or dusty conditions. This, of course, detracts from their cameras' versatility.
The new Olympus E-1 digital SLR camera tackles the dust problem head-on with its Olympus Supersonic Wave Filter. The front of the E-1's image sensor is protected from dust by a movable membrane connected to an ultrasonic transducer. During the camera's power-up cycle, the transducer vibrates the membrane at ultrasonic speeds. The motion of the membrane shakes off any dust, which is captured by a piece of sticky tape.
During our recent testing of the E-1, we took thousands of pictures with dozens of lens changes without a single dust spot in any of our images. Now there's no excuse for not cleaning up your photos.

Doe's any one know the history behind, or background of the multiple naming conventions for the equivalent risk functions. Different quant authors prefer using different names, does any one know why? which came first? why do some quants prefer one over the other. What is the history behind all of this.
ES - expected shortfall
CVaR - conditional value at risk
AVaR - average value at risk
ETL - expected tail loss
share|improve this question
Possibly the biggest road block to learning statistics are the varied and nonsensical naming. "[...]bad names reflect (or even result in) difficulties in understanding." Hurst, Joseph, colours and noises: The importance of names in an important natural behaviour, Demetris Koutsoyiannis itia.ntua.gr/getfile/792/1/documents/… – montyhall Mar 15 '13 at 5:40
2 Answers 2
No specific history. I'm not aware who introduced this measure initially. Most probably it came up as an example in the research papers on coherent risk measure. All names make sense to some extent:
Expected shortfall - as it's an expectation of losses
Conditional Value at Risk - as it can be written as $E[X |X >VaR_α(X)]$, i.e. conditional expectation
Average value at risk - as it can be written as $\frac{1}{1-\alpha}\int_{\alpha}^1VaR_{\beta}(X)d\beta$, which is essentially an average Expected Tail Loss - as it's expectation calculated in the tail of loss distribution
It's also sometimes called Tail VaR.
Personal preferences of people are usually based on their favorite risk management reference book.
share|improve this answer
I have also seen (in rough decreasing importance order): Mean excess loss, Tail conditional expectation and the variant C.T.E., Tail mean, Mean shortfall...
AVaR doesn't seem as common as the other three you mentioned.
Acerbi&Tasche 2002 discuss the difference between CVaR and ES. In practice there's little mention on reasons for each choice and rarely any differences have a significant role so that all variants become equivalent. The different naming flavours mostly originate historically from various areas: very roughly (from my concentrated and relatively limited sample) CVaR seems more en vogue among economists&traders, ES among risk managers, ETL among "statisticians", TVaR in econometrics, CTE among actuaries etc...
For other formulations of ES check also spectral and distortion risk measures.

For male North American barn swallows, the color intensity of their feathers is a signal of "quality," perhaps akin to an expensive sportscar or a spiffy suit. Researchers don't know yet exactly what this quality signal represents perhaps social status, good genes, or the ability to raise offspring but it plays a critical role when females decide which males will father their offspring.
Rebecca Safran and colleagues now report in the 30 September 2005 issue of the journal Science that male swallows with experimentally enhanced feathers are less likely to be cuckolded by their mates. By taking genetic samples both before and after they modified the male swallows' plumage using non-toxic inks, the authors showed that female barn swallows constantly assess the quality of their mate relative to other males in the population. DNA tests revealed that males with enhanced plumage sired more of the offspring in their nests.
The authors say this is the first study to reveal just how sensitive females are to very short-term changes in their mate's appearance; a slightly scruffy plumage at the wrong moment in the breeding season can cause an unwitting male to care for many young that are not his own.

text: An activity-based approach to optimize the ultrasonic-assisted extraction of antioxidants from Pericarpium Citri Reticulatae (Chenpi in Chinese) was developed. Response surface optimization based on a quantitative composition-activity relationship model showed the relationships among product chemical composition, antioxidant activity of extract, and parameters of extraction process. Three parameters of ultrasonic-assisted extraction, including the ethanol/water ratio, Chenpi amount, and alkaline amount, were investigated to give optimum extraction conditions for antioxidants of Chenpi: ethanol/water 70:30 v/v, Chenpi amount of 10 g, and alkaline amount of 28 mg. The experimental antioxidant yield under the optimum conditions was found to be 196.5 mg/g Chenpi, and the antioxidant activity was 2023.8 μmol Trolox equivalents/g of the Chenpi powder. The results agreed well with the second-order polynomial regression model. This presented approach promised great application potentials in both food and pharmaceutical industries.

|Quanser's Active Suspension|
The paper addresses the issue of delays that may occur in the PC-based control of an active suspension system. The signal delays can occur, for example, in a network-based control system or due to slow slow data acquisition. The research team proposes using state predictors with sliding-mode control to take delays into account. Both continuous-time and a discrete-time methods are designed and implemented on the Quanser Active Suspension system. Based on the results from simulations and hardware tests, the paper evaluates the effectiveness of these control strategies.

Abstract
The escape rate of surface state electrons on liquid helium was measured in the temperature interval 0.56<T<1.0 K for electron areal density below 5×107 cm−2, where the rate is independent of density. It is found that the escape rate is dominated by the scattering from the helium gas atoms in the vapor phase above 0.8 K, while it is dominated by that from ripplons (surface wave quanta) below 0.8 K. Quantitative agreement is obtained between our experiment and the theoretical calculation by Nagano et al.

the keyboard.
Connect the C button's touch up inside event to the clearDisplay method in Interface Builder.
Step 10: Number Input
Time to handle numeric input. When you open the keyboard it shows 0 on the display. If you tap a number key, it should replace the display to that number. Create a property named shouldClearDisplayBeforeInserting to implement this behavior.
Create a method named didTapNumber and connect it in Interface Builder to all the number buttons for the touch up inside event. The method uses the titleLabel of the button to determine which number was tapped.
Update the clearDisplay method as shown below.
The keyboard code is in a different target than your app. Because of this the debug logs aren't visible. To see the logs for the Calculator target, open the system log from the iOS Simulator.
Step 11: Dot Input
The button to insert a dot should add a dot to the display, but only if there isn't a dot present yet.
Step 12: Inserting Text
The button to insert text should add the calculator display text to the insertion point. To do this, we use the textDocumentProxy property as shown below.
Step 13: Handling Operations
Because we're implementing a simple keyboard that doesn't support expression trees, 1 + 2 * 3 will equal 9. We're going to use a simpler model in which the calculator has an internal memory slot on which it can apply operations.
Let's take a simple input in order to understand how the calculator algorithm works:
 - user taps 1, the display should change from 0 to 1
 - user taps +, the calculator should remember to add the next inputted number to 1
 - user taps 2, the display should change from 1 to 2
 - user taps *, the display and the internal memory of the calculator should change to 3, the calculator should remember to multiply the internal memory with the next inputted number
 - user taps 3, the display should remain 3
 - user taps =, the calculator should apply the last operation and the display should change to 9
Observations:
 - the calculator should remember the next operation to apply
 - after inputting a number if an operation or equal is pressed, the calculator should apply the last remembered operation
 - if the user presses two or more operations without inputting a number, the calculator should remember the last one
 - after an operation is applied, the display should update with the result
 - after a result is displayed, the display should clear before writing another number
In order to implement the calculator, we are going to need:
 - an internalMemory property that stores the temporary result
 - a property that stores the nextOperation
 - another one that to remember if it should apply the nextOperation after an operation is pressed
Create a method named didTapOperation and connect it to the operation buttons touch up inside event in Interface Builder. The method will use the button title to determine which operation was pressed.
Create and implement the computeLastOperation method.
Update the clearDisplayMethod as shown below. When the user starts to write the first number, the internal memory should be set to 0 and nextOperation should be addition. That way, after the user inputs the first number and presses an operation, the calculator will remember the inputted number.
Step 14: Finishing Touches
Let's use the IBInspectable declaration attribute to add a corner radius to the buttons and display. First, create a subclass of UIButton and UILabel.
In Interface Builder, select the buttons and change their class to RoundButton in the Identity Inspector. In the Attributes inspector, you should see the new corner radius attribute.
Do the same for the display label. Your keyboard should now look like this.
Conclusion
You should now be able to make a custom keyboard in iOS using the app extension APIs. Remember that every custom keyboard must have a way to switch to the next keyboard and that your keyboard cannot connect to the internet, access location services, or talk with its containing app by default, but you can request these capabilities.
The system will use the default keyboard for secure fields, such as password and phone number fields. Don't forget that the code for the custom keyboard lives in a separate target. Because of this the debug logs aren't visible. To see them, open the system log from the iOS Simulator.

I've recently come to grips in Turkish about the subtleties of translating "to like", and am wondering about how it works in a few other languages including Hungarian. What is the difference between:
I do know that "tetszik" is different from the others in that its structure is better translated as "to appeal to sb/sg" rather than "to like". However are there situations where natives prefer to use "kedvel-" over "szeret-" (and vice-versa)? What are some other ways Hungarians could use to translate "to like"? (i.e. did I miss including other verbs that Hungarians use to translate "to like" etc.?)
As I learn more languages, the more I realize that few true synonyms exist. It's more accurate to think of matters as a few words overlapping in meaning or register but the nuances remain distinct and beyond the grasp of a learner or not always covered in a big dictionary.

Archdeacon of Sheffield and Rotherham
The Archdeacon of Sheffield and Rotherham is a senior ecclesiastical officer within the Diocese of Sheffield, responsible for the disciplinary supervision of the clergy within the six area deaneries.
In 1884 the Archdeaconry of Sheffield, consisting of the rural Deaneries of Sheffield, Handsworth, Ecclesford, Rotherham and Wath, was created within the Diocese of York from part of the York archdeaconry.
In 1913 the deanery of Wath was split off to form part of the new Archdeaconry of Doncaster.
In 1942 the deaneries of Sheffield and Handsworth were abolished and replaced by the deaneries of Attercliffe, Ecclesall, Hallam, Laughton and Tankersley.
The current (2014) six deaneries comprise Attercliffe, Ecclesall, Ecclesfield, Hallam, Laughton and Rotherham.

Creating a Spring _USER_ Annotation
Spring Formatters and Converters make it easy to annotate fields for conversion from Objects to Strings, and are especially useful in web apps. But there is no easy or straightforward way to strictly validate the String before parsing into an object, without creating a custom Formatter. Here is a reusable solution that uses a RegexParserDecorator to decorate any Spring Formatter to apply a regex pattern, in turn creating a _USER_ annotation as an example implementation.
A little background: Spring 3.0 brought the Converter and Formatter framework with a concise _USER_ annotation, simplifying the Date to Object conversion that previously took custom binders or other wiring code. With _USER_ you can easily supply a String pattern used to parse and print a Date (or joda DateTime) object. However, the annotation does not strictly validate the String before converting to a Date. For instance, supplying a MM/dd/yyyy pattern does NOT enforce a 4 digit year. Instead a 2 digit year will be accepted and parsed using the SimpleDateFormat rules. Similar loose checking goes for 1 digit days and months, and also the slash character used as a separator. It would be easy to just throw the _USER_ tag onto your Date field except that _USER_ is only allowed on String fields. Combining _USER_ and _USER_ is what drove the creation of _USER_:
//sample usage using defaults for regex and pattern
private DateTime birthday;
Read more below for a discussion and snippets of code, and the entire codeset with comments is available on github.
The RegexParserDecorator: The first step is to create a Regex Parser class that will apply a regex pattern to validate a String for us. Creating this as a Decorator gives the added benefit that you can easily wrap any Spring Formatter to apply Regex patterns. The constructor takes a Parser to wrap and a regex to apply; and the parse method first validates against the regex before passing onto the decorated Parser:
public RegexParserDecorator(Parser parser, String regex) {
 this.parser = parser;
 this.regexPattern = Pattern.compile(regex);
public T parse(String text, Locale locale) throws ParseException {
 if (!regexPattern.matcher(text).matches()) {
 throw new IllegalArgumentException("Text does not match regex: " + text);
 return parser.parse(text, locale);
The _USER_ Annotation: Next step is to setup the annotation interface class. It is very similar to DateTimeFormat but adds the field to hold a regex. The default regex allows 1 or 2 digit days and months, requires a forward slash as the separator, and enforces a 4 digit year. This can be easily overriden when applying the annotation to a field by supplying your own (regex="", pattern="") extension. A pattern is still required so make sure your pattern and regex are paired appropriately.
_USER_({ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER})
public _USER_ StrictDateTimeFormat {
 public static final String REGEX_DEFAULT = "^(0?[1-9]|1[012])/(0?[1-9]|[12][0-9]|3[01])/dddd$";
 public static final String PATTERN_DEFAULT = "MM/dd/yyyy";
 String regex() default REGEX_DEFAULT;
 String pattern() default PATTERN_DEFAULT;
Spring then requires a StrictDateTimeFormatAnnotationFormatterFactory to wire the annotation with the parser. Nothing fancy here as it borrows heavily upon Spring's own JodaDateTimeFormatAnnotationFormatterFactory. The getParser method applies our regex to the DateTimeFormat functionality:
public class StrictDateTimeFormatAnnotationFormatterFactory implements
 AnnotationFormatterFactory {
 public Parser getParser(StrictDateTimeFormat annotation, Class fieldType) {
 DateTimeParser parser = new DateTimeParser(forPattern(annotation.pattern()));
 return new RegexParserDecorator(parser, annotation.regex());
 private DateTimeFormatter forPattern(String pattern) {
 return org.joda.time.format.DateTimeFormat.forPattern(pattern);
Hooking it all together: Here is the snippet from my applicationConfig.xml showing how the annotation is registered into Spring:

Hopefully this information is helpful in creating a reusable regex validating DateTime formatter for use in your own web application.

Reader question: "I have read that you need to leave your ball python alone when it's going through a shed. How soon after a shed can I handle my ball python?"
You can handle it immediately after a shed. You don't have to worry much about it, after the snake has shed. The hands-off period occurs before the ball python sheds — not after.
When the snake first starts to go "blue," it will start hiding more than usual. Its eyes will get cloudy, and the skin tone will become darker. This is a normal part of the shedding process. This is when you should avoid handling the ball python. The snake's eyes will have an opaque layer over them, so it won't be able to see very well. Handling at this time can cause the animal stress. How would you like to be picked up by something you couldn't see?
Ball pythons feel vulnerable when they're going through a shed cycle. That's why you should avoid handling them, until after they shed.
When your snake goes into the "blue" phase leading up to a shed, you might want to increase the relative humidity inside the enclosure. Snakes use moisture to separate the old skin layer from the underlying layer. That's why it's so important to keep your ball python well hydrated — it helps them shed properly, all in one piece.
You can handle the ball python anytime after a shed. Just leave it alone when it's going into the shed. If you have additional questions about ball python care, you can download our e-book on the subject. You can also post a question to our Q&A forum.

Why is the Duchess of Cornwall replacing Prince Harry at events?
The Field of Remembrance is an important tradition for UK soldiers, honoring those who lost their lives while serving. When the temporary memorial garden opens up the Thursday before Remembrance Sunday, members of the Royal Family traditionally participate in the opening ceremony. In 2020, Camila, Duchess of Cornwall represented the House of Windsor instead of Prince Harry, who usually does the honors.
In previous years, Prince Harry led the commemorations at the opening of the Field of Remembrance. 2020 marks the first year since 2015 Harry wasn't on hand to assist with the ceremonies. While many assume this is because Prince Harry and Meghan Markle took a step back from royal duties, the Field of Remembrance is a special occasion for Harry and other military veterans.
Honoring the fallen soldiers
Since 1928, The Poppy Factory has set up a temporary graveyard honoring fallen soldiers outside St. Margaret's Church near Westminster Abbey. Poppies are used in the UK as a tribute to the military who fought in world wars along with other international conflicts.
The Poppy Factory is a strong supporter of the British Armed Forces. For nearly a century, the company has produced poppy flowers for both The Royal British Legion and the Royal Family in preparation for Remembrance Day. The company is also well known for supporting veterans with mental or physical disabilities and helping them find work once they return from service.
Prince Harry served in the British military from 2005 to 2015, with a focus in the Army Air Corps. Following in his father, uncle, and brother's footsteps, Harry was a helicopter pilot in the Air Corps, becoming a Squadron Leader as well as Lieutenant Commander.
Since ending his short service commission, Harry tends to represent the Royal Family at any military-related engagements. This includes the Field of Remembrance commemorations. Once Harry took over from Prince Philip as the Captain General of the Royal Marines, it was expected of Harry to oversee all military engagements.
Prince Harry is far from the only royal to attend such events. Camila, Duchess of Cornwall was actually supposed to attend last years' Field of Remembrance event alongside Prince Harry and Meghan Markle, but health issues kept her from going.
Why the Duchess of Cornwall?
Due to COVID-19 travel restrictions, Harry wasn't able to come back to the UK in time for Remembrance Day events. Camila, Duchess of Cornwall, recently took over the title of Colonel-in-Chief of The Rifles, so this would be her first event serving under her new title. Camila also has a history with the Poppy Factory, serving as a patron of the organization since 2013.
At the event, Camila laid a Cross of Remembrance in front of the "Last Post", on the signal of the bugle. The Duchess of Cornwall was only one of a handful of people invited to the ceremony, as the second lockdown in the UK began on the 5th.
Though Prince Harry isn't participating in any of the Remembrance Day this year, not all traditions are being broken. Prince Philip is still set to place a wreath down on the eleventh hour of Remembrance Day to lead the UK in a moment of silence. The Queen will most likely oversee the ceremony from afar due to COVID-19 as well.
Are you surprised Prince Harry isn't appearing at the Day of Remembrance ceremony this year? Do you believe he would have participated if COVID-19 hadn't halted travel? Let us know in the comments!

What is A Flood Vent?
Updated: Jun 25, 2019
Engineered flood vents protect residential houses and commercial buildings in floodplains by preventing hydrostatic pressure buildup that can destroy walls and foundations.
An Engineered Flood Vent:
- Relieves (rather than resists) hydrostatic pressure on foundation walls during a flood event. The flood vent must allow for the automatic entry and exit of flood waters without human intervention.
- Passively equalizes hydrostatic loads on enclosure walls below the BFE.
- Must allow bi-directional relief of the flood waters regardless of the direction of flow.
- Is a "wet floodproofing" technique.
