What are the common faults of hydraulic forklift mast
What are the common faults of hydraulic forklift mast
 - 2022-05-07
As we all know, the forklift mast is a very important component for forklifts, but the forklift mast may also have some failures at the same time. So, what are the common faults of forklift mast? The following hifoune forklift manufacturer will give you a good introduction to the common faults of the forklift mast?
forklift mast
1. The oil return pipe of the lifting cylinder leaks seriously and falls off automatically
The main reason is that the oil seal between the lift cylinder and the piston rod is damaged. The main solution is to replace the corresponding oil seal, but in the implementation process, it should be noted that workers often do not work according to the methods and skills. Therefore, it is necessary to formulate a corresponding hard iron sheet fixing ring, wrap the oil well, clamp it with pliers and send it into the cylinder to prevent its waste. The made slippers can be used many times, saving resources.
2. The lifting of the left and right lifting piston rods is not synchronized
The problem is that the nylon guide between them swells. The solution is to effectively integrate the nylon guide sleeve during the implementation process, and cut the nylon guide sleeve 3mm according to the hacksaw to make it have a certain opening gap to ensure its expansion value and avoid problems during use.
3. No lift, no direction
The cause of this problem is the imperfect hydraulic oil, the contaminants in it, and the rupture of the hydraulic oil filter. To solve the first two problems of this main scheme, new hydraulic oil can be replaced in time. The latter problem can be Solved by replacing the effective filter in time. These solutions are mainly to illustrate the fundamental solution of the problem, more importantly, this kind of problem occurs in the actual development process, indicating that the hydraulic system is blocked. It is impossible to fundamentally solve the problem by simply replacing the new hydraulic oil, and it is necessary to clean the multi-way reversing valve to fundamentally solve the problem.
4. The steering wheel is not flexible when turning the steering wheel
The reason for this problem is that the steering gear positioning reed is broken and the steering cylinder leaks. The solution is to rotate the direction in situ. It feels too light. It is obvious that there is a problem with the positioning reed, and it is possible to replace it. If you feel a certain force when turning the steering wheel, but the steering wheel is very inflexible, it can be rotated 360 degrees to the left or right, which means that there is a problem with the oil seal on the steering cylinder piston, resulting in internal oil leakage, and the oil seal needs to be replaced.
5. The piston rod of the lift cylinder shakes during the lift
If there is a problem, it should be judged that the hydraulic oil in the mailbox is not perfect, causing the problem of the hydraulic pump pressure. After that, it needs to be clear that there is air in the hydraulic line to the cylinder piston section. The main way to solve the problem is to increase the hydraulic oil. If it doesn't work properly, you need to loosen the return line of the lift cylinder, lift the cylinder to the top, and then lower it to the bottom . Repeated operations can bleed the air present in the hydraulic lines, effectively solving the problem.
The above points are the failure problems often encountered during the use of the forklift gantry. If you are using the forklift, there will be problems on the gantry or there are other faults related to the forklift gantry. You can also follow We communicate and exchange .

A Laboratory Landscape for the Outskirts of Bangkok, Thailand
As metropolitan Bangkok sprawls and expands, the boundaries of the nearby Dong Phayayen-Khao Yai (DPKY) Forest Complex and UNESCO World Heritage site are under increasing pressure. This project seeks to preserve the integrity of the UNESCO-mandated buffer zone between the Thai capital and the Forest Complex by transforming it into a vast agricultural testing zone.
Blanketed with rice paddies and dotted with agricultural laboratory buildings and schools, the buffer zone would become a testing field, focusing on studying and effectively producing food for Bangkok's growing population. The project imagines a form of bargain: the more productive this agricultural "laboratory," the more likely it is to remain an intact and effective protector of the World Heritage site it surrounds.

Well, summer is officially behind us. The first day of autumn was Monday, September 22 which was a beautiful day. Sunny and warm temperatures allowed the farmers to get back into the fields after rain showers on Sunday.
Fall also arrived without any major frosts being reported in the area. The mercury dropped to near freezing on August 23 and on September 14 it dipped again to zero but left no damaging effects.
The first "killing" frost of the year came on September 24 when the low registered was -1.5°C. Andrew Giraudier, who records the daily temperatures for Environment Canada said that the average date for first frost, using data collected over the past 34 years, is September 20.
We got a full 10 days more of frost free weather over last year when Jack Frost put a frosty end to many gardens in the area with an overnight low of -8.5°C. Giraudier also noted that the recorded temperatures could vary slightly around town with different elevations that are present within the town of Coronach.

Developing sustainable tidal energy
West Zeeuws-Vlaanderen has a 250-hectare inland nature and recreational area that is directly connected to the Westerschelde via a tidal culvert. The tidal culvert is constructed in the primary flood defence and with each tidal cycle, approximately 1 million m3 of sea water flows in and out of the coastal area behind the dunes, enriching the natural life. Should an imminent storm surge arise, flaps located in the tubes of the tidal culvert will close to ensure safety against flooding. Iv provided the reference design of the tidal culvert, the replacement flood defence system and provided system-oriented contract management.

should always provide a description.
type
Defines the type of attribute value. The valid types are the members of the list attributes.Schema.TYPES, currently STRING, NUMBER, BOOLEAN, MAP, and LIST; please use those symbolic names rather than the literals to which they are equated.
support_status
Defines current status of the attribute. Read Heat Support Status usage Guide for details.
If attributes are defined, their values must also be resolved by the plug-in. The simplest way to do this is to override the _resolve_attribute method from the Resource class:
def _resolve_attribute(self, name):
 # _example_get_physical_resource is just an example and is not
 # defined in the Resource class
 phys_resource = self._example_get_physical_resource()
 if phys_resource:
 if not hasattr(phys_resource, name):
 # this is usually not needed, but this is a simple
 # example
 raise exception.InvalidTemplateAttribute(name)
 return getattr(phys_resource, name)
 return None
If the plug-in needs to be more sophisticated in its attribute resolution, the plug-in may instead choose to override FnGetAtt. However, if this method is chosen, validation and accessibility of the attribute would be the plug-in's responsibility.
Also, each resource has show attribute by default. The attribute uses default implementation from heat.engine.resource.Resource class, but if resource has different way of resolving show attribute, the _show_resource method from the Resource class will need to be overridden:
def _show_resource(self):
 """Default implementation; should be overridden by resources.
 :returns: the map of resource information or None
 """
 if self.entity:
 try:
 obj = getattr(self.client(), self.entity)
 resource = obj.get(self.resource_id)
 if isinstance(resource, dict):
 return resource
 else:
 return resource.to_dict()
 except AttributeError as ex:
 LOG.warning("Resolving 'show' attribute has failed : %s",
 ex)
 return None
Property and Attribute Example
Assume the following simple property and attribute definition:
properties_schema = {
 'foo': properties.Schema(
 properties.Schema.STRING,
 _('foo prop description'),
 default='foo',
 required=True
 ),
 'bar': properties.Schema(
 properties.Schema.INTEGER,
 _('bar prop description'),
 required=True,
 constraints=[
 constraints.Range(5, 10)
 ]
 )
}
attributes_schema = {
 'Attr_1': attributes.Schema(
 _('The first attribute'),
 support_status=support.Status('5.0.0'),
 type=attributes.Schema.STRING
 ),
 'Attr_2': attributes.Schema(
 _('The second attribute'),
 type=attributes.Schema.MAP
 )
}
Also assume the plug-in defining the above has been registered under the template reference name 'Resource::Foo' (see Registering Resource Plug-ins). A template author could then use this plug-in in a stack by simply making following declarations in a template:
# ... other sections omitted for brevity ...
resources:
 resource-1:
 type: Resource::Foo
 properties:
 foo: Value of the foo property
 bar: 7
outputs:
 foo-attrib-1:
 value: { get_attr: [resource-1, Attr_1] }
 description: The first attribute of the foo resource
 foo-attrib-2:
 value: { get_attr: [resource-1, Attr_2] }
 description: The second attribute of the foo resource
Life Cycle Handler Methods
To do the work of managing the physical resource the plug-in supports, the following life cycle handler methods should be implemented. Note that the plug-in need not implement all of these methods; optional handlers will be documented as such.
Generally, the handler methods follow a basic pattern. The basic handler method for any life cycle step follows the format handle_<life cycle step>. So for the create step, the handler method would be handle_create. Once a handler is called, an optional check_<life cycle step>_complete may also be implemented so that the plug-in may return immediately from the basic handler and then take advantage of cooperative multi-threading built in to the base class and periodically poll a down-stream service for completion; the check method is polled until it returns True. Again, for the create step, this method would be check_create_complete.
Create
handle_create(self)
Create a new physical resource. This function should make the required calls to create the physical resource and return as soon as there is enough information to identify the resource. The function should return this identifying information and implement check_create_complete which will take this information in as a parameter and then periodically be polled. This allows for cooperative multi-threading between multiple resources that have had their dependencies satisfied.
Note once the native identifier of the physical resource is known, this function should call self.resource_id_set passing the native identifier of the physical resource. This will persist the identifier and make it available to the plug-in by accessing self.resource_id.
Returns
A representation of the created physical resource
Raise
any Exception if the create failed
check_create_complete(self, token)
If defined, will be called with the return value of handle_create
Parameters
token – the return value of handle_create; used to poll the physical resource's status.
Returns
True if the physical resource is active and ready for use; False otherwise.
Raise
any Exception if the create failed.
Update (Optional)
Note that there is a default implementation of handle_update in heat.engine.resource.Resource that simply raises an exception indicating that updates require the engine to delete and re-create the resource (this is the default behavior) so implementing this is optional.
handle_update(self, json_snippet, tmpl_diff, prop_diff)
Update the physical resources using updated information.
Parameters
 - json_snippet (collections.abc.Mapping) – the resource definition from the updated template
 - tmpl_diff (collections.abc.Mapping) – values in the updated definition that have changed with respect to the original template definition.
 - prop_diff (collections.abc.Mapping) – property values that are different between the original definition and the updated definition; keys are property names and values are the new values. Deleted or properties that were originally present but now absent have values of None
Note Before calling handle_update we check whether need to replace the resource, especially for resource in *_FAILED state, there is a default implementation of needs_replace_failed in heat.engine.resource.Resource that simply returns True indicating that updates require replacement. And we override the implementation for OS::Nova::Server, OS::Cinder::Volume and all of neutron resources. The base principle is that to check whether the resource exists underlying and whether the real status is available. So override the method needs_replace_failed for your resource plug-ins if needed.
check_update_complete(self, token)
If defined, will be called with the return value of handle_update
Parameters
token – the return value of handle_update; used to poll the physical resource's status.
Returns
True if the update has finished; False otherwise.
Raise
any Exception if the update failed.
Suspend (Optional)
These handler functions are optional and only need to be implemented if the physical resource supports suspending
handle_suspend(self)
If the physical resource supports it, this function should call the native API and suspend the resource's operation. This function should return information sufficient for check_suspend_complete to poll the native API to verify the operation's status.
Returns
a token containing enough information for check_suspend_complete to verify operation status.
Raise
any Exception if the suspend operation fails.
check_suspend_complete(self, token)
Verify the suspend operation completed successfully.
Parameters
token – the return value of handle_suspend
Returns
True if the suspend operation completed and the physical resource is now suspended; False otherwise.
Raise
any Exception if the suspend operation failed.
Resume (Optional)
These handler functions are optional and only need to be implemented if the physical resource supports resuming from a suspended state
handle_resume(self)
If the physical resource supports it, this function should call the native API and resume a suspended resource's operation. This function should return information sufficient for check_resume_complete to poll the native API to verify the operation's status.
Returns
a token containing enough information for check_resume_complete to verify operation status.
Raise
any Exception if the resume operation fails.
check_resume_complete(self, token)
Verify the resume operation completed successfully.
Parameters
token – the return value of handle_resume
Returns
True if the resume operation completed and the physical resource is now active; False otherwise.
Raise
any Exception if the resume operation failed.
Delete
handle_delete(self)
Delete the physical resource.
Returns
a token containing sufficient data to verify the operations status
Raise
any Exception if the delete operation failed
Note
As of the Liberty release, implementing handle_delete is optional. The parent resource class can handle the most common pattern for deleting resources:
def handle_delete(self):
 if self

Parachute nightdress among recycled items on display at Devon fashion exhibition
By Steven Morris,
Some of the garments in the exhibition are made of elegant silk, others of rough-looking wool or scratchy nylon – but what they all have in common is that they have been repaired, remodelled and reused, sometimes over the course of centuries.
There is a long-sleeved waistcoat made in the late 17 t th century and then adapted and preserved over 300 years, wedding dresses handed down from mothers to daughters and brought up to date with clever tweaks, even clothes that were created during the second world war out of parachutes and old army blankets when fabric was rationed.
The garments are part of the Thirsty for Fashion exhibition opening at the National Trust's Killerton House in Devon . The aim is to make people think about how they buy and look after clothing in this fast-fashion, throwaway world.
"Recycling and reusing clothing has been commonplace throughout history," said Shelley Tobin, the costume curator at Killerton. "This exhibition asks the question: can we learn lessons from these past practices and reapply forgotten skills to look after our clothes and make them more sustainable?
"The items exhibited show that we only need look to history to discover ways to ensure that the clothing we buy, make and wear is durable, ethical and avoids waste."
In contrast, the highlight of the first room is a sleeved waistcoat made of silk in about 1690. It was handed down through the generations and at one point the horizontal pocket flaps were replaced with more fashionable vertical ones. In the early 20th century it was turned into a fancy dress costume and in the 1980s someone conserved it by relining it.
Tobin said some modern makers were reusing clothes and fabric. So in the same cabinet as the waistcoat is a much more modern piece, a suit made in 2022 out of old denim jeans by the London fashion company ELV Denim .
Another highlight is a "transformation dress" made in 1870 and consisting of a billowing skirt that could be matched with a modest long-sleeved, high-cut bodice for the day or a more risque one for the evening. "It was made of expensive material so they wanted to get the most use out of it possible," said Tobin.
One feature of the exhibition is the testimony of friends and volunteers of Killerton – home to the National Trust's biggest fashion collection with more than 20,000 items of historical clothing and accessories – about their favourite vintage pieces.
Charlotte Eddington, for example, describes her beloved 1970s woollen Guernsey jumper that she persuaded her dad to hand down to her when it became too tight for him. It reminds her of camping and fishing in Northumberland as a child.
Sarah Parry, a gardener, tells how she wore her mother's 1985 wedding dress when she got married last year. "It's so floaty and frothy and ethereal," she said. Parry added a green waistband give it a modern twist. "It was so fulfilling to give the dress a second life."
A striking set of clothes on display was made during and after the second world war when fabric was rationed and the government launched the "make do and mend" campaign. "It was very difficult to get hold of most fabric," said Tobin. "If you could come by, for example, a parachute you could use it."
The show includes a nightdress made in about 1943 from a nylon parachute – but Tobin's favourite piece is a dressing gown made in the late 1940s by an Exeter woman out of surplus army blankets livened up with a beautiful green trim and belt.
"I think it's ingenious that she made it into this very elegant and durable dressing gown," said Tobin. "We hope the exhibition will lead to discussions about whether we can learn from past practices and reapply forgotten skills to look after our clothes, and how can fashion respond to the changing climate, environmental concerns and the cost of living crisis."
The exhibition runs from 11 February to 5 November 2023.

The Spanish Competition Authority encourages more competition in the medical devices market
Report IPN/CNMC/025/18 issued by the Spanish Competition Authority on the draft of Royal Decree of reimbursement and prices of medical devices
Jordi Faus
Capsulas Nº 197
When the Ministry of Health started working on this Royal Degree, it agreed to request the Spanish Competition Authority to issue a report about it. The Spanish Competition Authority is usually grateful about this sort of requests, because they allow its participation aiming both to improve the functioning of the markets concerned and to reasonably maintain effective competition in such markets. The Spanish Competition Authority understands that this regulation may have a significant impact on competition and issues some recommendations.
Main proposals
The analysis of the Spanish Competition Authority departs from the idea that the market of medical devices is rather complex due to concentration of supply (the first 5 main companies have more than 50% of medical devices reimbursed by the NHS). Also, the medical devices sector is well-known by the Spanish Competition Authority, due to the several cases analysed in the past years, sanctioning many companies for illegal activities.
The Spanish Competition Authority makes, among, others, following recommendations:
1) To review the system for fixing prices and specially margins, pointing out that the system applicable to medicines does not necessarily have to apply to medical devices.
2) To treat in equal terms both reimbursed medical devices and new ones. This may result in a price review of reimbursed medical devices aiming to avoid harming companies who wish to access the market.
3) To reconsider the roll of retail pharmacies when dispensing reimbursed medical devices, opening the door to dispensation at home and in NHS centres.
4) To apply the system of homogeneous groups to reinforce competitive tension. Under this system (applicable to medicines), the pharmacist dispenses the product having the lowest price within its group.
5) To introduce demand and rational use policies. The Spanish Competition Authority supports generic prescription and substitution of products by the pharmacist, but it also encourages providing more information to patients.
6) To improve the reasoning behind decisions. The Spanish Competition Authority has insisted on this matter several times and no steps forward have been taken so far.
Final comment
The recommendations of the Spanish Competition Authority usually come after a strict analysis of the concerned market. However, this report lacks some delicacy. Having excessive competitive tension in a market where the purchaser has so much power, can lead some companies to exit such market. This would result in patients not being able to access some valuable products. This is a delicate matter and it must be handled with prudency.

The electric charge attracts the uncharged water particles. Water Conducts electricity and draws the charge from the spoon. Tiny water particles in the air also take up electricity.
NOTE: I had to dry the sweater in the dryer for a few minutes to properly charge it before hand. Enjoy!

text: This armor can be identified by its decoration as having belonged to Pedro II (reigned 1683–1706). The decoration includes the crowned monogram PR for Pedro Rex (Pedro the King) and the cross of the commander of the Order of Christ, a hereditary office held by the kings of Portugal.Harquebusiers were armored cavalrymen generally equipped with a carbine (known as a harquebus) carried at the right side on a shoulder belt, a pair of pistols holstered at the front of the saddle, and a sword. This form of armor, consisting of a triple-barred helmet, a cuirass with a bulletproof reinforcing breastplate, and an elbow gaunlet, was commonplace in England up to about 1645. The armor of King Pedro is significant not only as a very late example of this type but also as the probable work of the London armorer Richard Holden. A very similar armor made by Holden in 1686 for James II of England (reigned 1685–88) is in the Royal Armouries in the Tower of London. The armor is shown with an associated buff coat. This sturdy leather defense, which provided effective protection against sword cuts, was worn throughout the seventeenth century, first in conjunction with armor and later alone.

Nashville, TN – The Tennessee Department of Transportation (TDOT) has completed a year-long Statewide Aviation Economic Impact Study, finding Tennessee's public-use airports contribute $40 billion to the state's economy and support 220,936 jobs in Tennessee.
"Tennessee's 78 public-use airports are critical components of the state's transportation network, linking and providing access to regional, national, and global transportation systems," said TDOT Commissioner Clay Bright.
This Economic Impact Study represents the 2019 annual economic impact of the aviation system on the state's economy. Therefore, the study is a good representation of the annual economic impact of the aviation system during a non-pandemic world.
The study analyzed the economic impacts of on-airport activities, off-airport activities, multiplier impacts, and freight/cargo. Examples of on-airport activities include economic impacts from business tenants, airport construction spending, and airport employment. Off-airport impacts include visitor spending. Visitor spending generated 69,965 jobs and $9 billion in business revenue to the state in 2019. Analysis found that freight/cargo impacts generated 82,357 jobs and $19 billion in business revenue.
"A safe, secure, efficient, and resilient aviation system is essential to our state's physical, economic, and social health," said Michelle Frazier, Director of TDOT's Aeronautics Division. "This report recognizes aviation as a driver of the economy, including economic recovery."
The Aviation Economic Impact Study details the $40 billion economic impact of aviation in Tennessee. Airports serve as a catalyst for people to conduct business, serve clients, and ship cargo. Having a well-maintained and diverse aviation system supports a robust economy.

The Machine-SUIF Control Flow Graph Library
Release version
Glenn Holloway and Michael D. Smith
Division of Engineering and Applied Sciences
Harvard University
The Machine-SUIF CFG library provides an abstraction of control flow graphs with nodes containing lists of machine instructions. Such a CFG can be used to replace the linear instruction-list representation of the body of a procedure being compiled. The library supports translation of the linear representation to and from CFG form, transformation of a CFG by adding, reconnecting, and removing nodes, and fine-grained control over individual program instructions within CFG nodes. It allows precise control of program layout, to ensure that re-linearization leaves instructions in the desired order.
The CFG library is lean by design. We have factored tools for control-flow and data-flow analysis into separate libraries, based on this one. Users can pick the functionality they need, and they can build other CFG-based tools without incurring overhead for features they don't need.
This document discusses the Machine-SUIF control flow graph (CFG) library. It discusses design goals, the interface to the library, implementation decisions, current status, and planned updates.
The Machine-SUIF CFG library presents an abstraction of control flow graphs built on the basic instr_list structure of the Machine-SUIF system. It allows you to build CFGs and to transform them by rearranging and reconnecting nodes. Machine SUIF provides companion libraries based on this one that support control-flow and data-flow analysis.
The CFG library consists of files in the cfg subdirectory of the machsuif distribution package. This document describes its design and use. It assumes that the reader is familiar with the SUIF and Machine-SUIF systems and has read the machine library documentation.
The following section discusses the development and research goals that drove the design of our CFG library. Section [->] describes our view of how the library will be used. Sections [->] through [->] describe the programming interface provided by the CFG library, and they provide some notes on its implementation.
Goals for the CFG Library
This section lists our goals for the CFG library.
The next section gives an overview of how we expect the library to be used.
One of the things that makes the control-flow graph such a useful compile-time abstraction is that it abstracts away from sequential code. It enables graph-based transformations and allows them to be expressed without reference to a linear code layout. By parceling a procedure's instruction list into basic blocks, we make it efficient to reorder the blocks without having to splice their instructions into a new linear order.
The question arises whether to manage the control instructions within a CFG so that at all times they correctly reflect some linear order. Take the code for a simple if... then... else... statement. Suppose the code generator has produced a conditional branch instruction to the else statement, and has place the then statement after the if test. The then code ends with a jump around the else statement to the join point. Breaking basic blocks after control instructions will put a jump at the end of the node for the then statement, and none at the end of that for the else statement, which just falls through. If a transformation now inverts the sense of the conditional branch and adjusts CFG flow edges accordingly in the CFG, what should be done to the instruction lists in the then and else nodes? The natural re-linearization algorithm would remove the jump from the end of the then node and insert one at the end of the else node. Should such jump adjustments be made every time the CFG changes?
For many kinds of optimization, this isn't important, either because they change no control flow at all, or because they are not concerned with the precise schedule of instructions. For these, it's fine to leave the selection of a final layout and the adjustment of jump instructions to the library method that re-linearizes the flow graph.
For other optimizations, like instruction scheduling and code placement, it's essential to know exactly what instructions will appear where, and in fact, to be able to control such decisions precisely.
The Machine-SUIF CFG library allows you to control the layout relationship between any pair of nodes, but it also allows you to leave the layout of part or all of a CFG unspecified. At the time two nodes become constrained to be adjacent in memory order, the library may remove or insert a trailing jump instruction to achieve consistency with this constraint. But in the absence of layout constraints, it doesn't insert or remove jumps as the graph is transformed.
To implement this policy efficiently, the library must have quick access to the control-transfer instruction (CTI), if any, in each node. It relies on there being at most one CTI, and it keeps a record of its position. As a client, you're free to modify any of the instructions in a block, but when you change the CTI, you're expected to call a library method to reflect the change. [The library doesn't assume that CTI instruction, will be the last in the node; that would make it difficult, for example, to support scheduling for delayed-branch architectures by placing instructions after the control instruction of a block. The library doesn't provide full support for such architectures; e.g., when building a CFG, it always breaks basic blocks at control transfer instructions. Completing the support for target code with delay slots following branch instructions would require subclassing to perform the necessary construction-time adjustments.] Common operations on nodes, such as replacing one of its control successors, update the CTI directly, without requiring the programmer to make changes at both the graph level and the instruction level.
We have tried to keep the CFG library, and particularly its class interfaces, lean. Though Machine SUIF provides flow analysis libraries based on our CFG abstraction, users may want to write their own. We've tried to make it easy to do so.
Class Cfg
The two main classes used in the CFG library are Cfg and CfgNode. A Cfg represents an entire control flow graph for a procedure. The nodes within a Cfg have class CfgNode. The functions operating on class Cfg handle the graph overall: graph expansion and simplification, graph validation and printing, and the enumeration of nodes and edges. Those operating on CfgNode are about managing a node's relations with its control and layout neighbors and out keeping its code consistent with those relations.
CFG construction
To create a CFG or to normalize the form of an existing CFG, use the following functions:
= (U->)
Cfg* new_cfg(InstrList*, bool keep_layout = false,
 bool break_at_call = false,
 bool break_at_instr = false);
void canonicalize(Cfg*, bool keep_layout = false,
 bool break_at_call = false,
 bool break_at_instr = false);
void remove_layout_info(Cfg*);
void fix_layout(Cfg*);
Creation function new_cfg parses a linear list of instructions into basic blocks. There are options for determining precisely what constitutes a basic block and whether the original linear layout of the instructions should be reflected by initial layout constraints. Given an existing CFG, you may want to ensure that it has the same form as if built from scratch with a given option set. The canonicalize function serves this purpose.
Each of the flags keep_layout, break_at_call, and break_at_instr is optional. When keep_layout is true, the CFG gets node-layout constraints reflecting the program's initial linear layout. When break_at_call is true, each procedure-call instruction is treated as a CTI, so that it terminates the CFG node that contains it. break_at_instr means that each node of the graph contains only one instruction.
The remove_layout_info function clears all layout constraints in a given graph.
The fix_layout function, on the other hand, imposes layout constraints wherever they don't already exist. In some cases, it inserts additional insert unconditional branch instructions. That happens when a potential fall-through edge in the CFG cannot actually be realized by fall-through because of a conflicting layout constraint. Likewise, fix_layout may eliminate an unconditional branch if it turns out to be equivalent to fall-through in the newly-imposed layout.
CFG inspection
= (U->) [D->]
CfgNode* get_node(Cfg*, int pos);
CfgNode* get_node(Cfg*, CfgNodeHandle);
CfgNode* node_at(Cfg*, LabelSym*);
int nodes_size(Cfg*);
CfgNodeHandle nodes_start(Cfg*);
CfgNodeHandle nodes_last(Cfg*);
CfgNodeHandle nodes_end(Cfg*);
CfgNode* get_entry_node(Cfg*);
CfgNode* get_exit_node(Cfg*);
void set_entry_node(Cfg*, CfgNode*);
void set_exit_node(Cfg*, CfgNode*);
Their capsule summaries:
get_node(cfg, pos) returns the node at pos in cfg's node list, where pos is a position in the list (either a zero-based integer or a handle).
get_node(cfg, label) returns the node of cfg at label.
nodes_size(cfg) returns the number of nodes in cfg.
nodes_start(cfg) returns a handle on the first element of cfg.
nodes_last(cfg) returns a handle on the last element of cfg.
nodes_end(cfg) returns the sentinel handle for cfg.
get_entry_node(cfg) returns cfg's entry node.
get_exit_node(cfg) returns cfg's exit node.
set_entry_node(cfg, entry) sets cfg's entry node to entry.
set_exit_node(cfg, exit) sets cfg's exit node to exit.
Type CfgNodeHandle is an abbreviation for an STL iterator.
= (U->)
typedef list::iterator CfgNodeHandle;
The nodes_ functions are so named because the sequence of node pointers in a Cfg is called nodes. These functions are frequently used; since a Cfg

High-Intensity Ultrasound OK for Cesarean Scar Pregnancy
(HealthDay News) — High-intensity focused ultrasound (HIFU) can play a role in treating cesarean scar pregnancy (CSP), according to a small study published in the October issue of the American Journal of Obstetrics & Gynecology.
Juhua Xiao, MD, from the Jiangxi Maternal and Child Health Hospital in Nanchang, China, and colleagues treated 16 patients with CSP with ultrasound-guided HIFU ablation. Disappearance of CSP mass, undetectable serum beta human chorionic gonadotropin, and no serious complications such as severe bleeding, uterine rupture, or hysterectomy were the criteria used to define successful treatment.
The researchers found that after 2–5 treatment sessions, the mean time for achieving undetectable serum beta human chorionic gonadotropin was 4.94 weeks, and the mean time for CSP mass disappearance was 6.69 weeks. In 1–2 days the moderate abdominal pain in three patients subsided, while nine patients experienced mild vaginal bleeding (<30mL) that resolved within 2–3 days. At follow-up, all 16 patients had recovered their normal menstruation function.
"These preliminary results suggest that ultrasound-guided HIFU ablation is a noninvasive, feasible, and effective method for the treatment of CSP," the authors write.


"Form (ever) follows function" is a principle that was coined by the American architect Louis Sullivan. The phrase has been associated with modern architecture and industrial design in the 20th century. The idea of the principle is that the shape or structure of an object is primarily based upon the objects function or purpose. The way something looks should be determined by its function; its form should always have a purpose.
A good example that follows this principle is the Guggenheim Museum in New York City. The building was designed by architect Frank Lloyd Wright, also Sullivan's assistant. It's spiral structure was intended to allow visitors to easily view the artwork within the museum. The spiral staircase creates a good flow of traffic.
boxworks15-140An example that can relate to exhibit design is a hanging box banner. The image to the right is a hanging banner from Box Works 2015. It in the shape of a cube so that the sign can be seen and read from multiple angles. If it were 2-dimensional then the banner would only be read from 2 angles.
Sometimes there instances where the principle is not followed. An object's form can be purely just for aesthetics and looks; it's form can be more important than its function. If there's no significant function, then design can rely mainly on form. Below is an exhibit designed for Bombardier. The angular overhang is in the shape of a kite or can represent the wings of an airplane. It's form is more significant to its function because no matter its shape, it will still have the same function.

The Costa Rican unit of the North American Chamber of Commerce (AmCham) has urged the new President Carlos Alvarado to focus on stemming the fiscal deficit and improving infrastructure within his first 100 days in office.
Topping the list of suggestions is that the government should slam the brakes on excessive public spending, one of the major culprits of inflation and high production costs.
With traffic jams becoming commonplace in most major cities, businesses have been forced to fork out on transportation, so improved infrastructure is also key.
The lobby group has also expressed concern at the growing crime rate in the country, urging the government to reinforce the police force and allow security forces to coordinate with each other to clamp down on criminals.
Soaring electricity prices is another factor hurting the competitiveness of companies. As electricity is basic infrastructure, the government needs to ensure that power prices are stable and cost-effective, AmCham has argued.
"We have always been characterized by working together with the government, proposing strategies and actions aimed at strengthening the country's competitiveness," stated Elías Soley, President of AmCham, in press release.
Educational institutes in the country are not generating enough professionals and technicians required by businesses, says AmCham. "There is an urgent need for the government to reform the education system to prevent companies from 'importing' talent."
The organization has also called on the government to develop a roadmap for utilizing the money earmarked for promoting innovation.

Melanin content in skin cells 5 days after treatment
It is shown that the melanin content in all the skin cells is lesser as compared to the baseline. The test using Thiospot (combination of 3 ingredients) displayed the most significant decrease in melanin content.
With this, we can conclude that Thiospot can effectively decrease melanin content in the skin, improving the appearance of hyperpigmentation.
The comparison of cell vitality and effectiveness in melanin content reduction between Thiospot Intensive and Hydroquinone 4%
Three concentrations were used to test the cell vitality and effectiveness between Thiospot Intensive and Hydroquinone 4%. It was observed that the effectiveness in decreasing the melanin content using Thiospot Intensive is higher throughout all three tests without having to compromise on the cell vitality. As the concentration increase, cell vitality for Hydroquinone 4% was severely affected and there was a significant decrease in efficacy.
This study shows that Thiospot Intensive in more superior as compared to Hydroquinone 4% for both cell vitality and effectiveness in decreasing melanin in the cells.Data on file General Topics: ABICH 2012


Starting Geyser and Caldera jobs from Cheyenne
Interactive jobs | Batch jobs | Compiling your code
Cheyenne HPC system users run jobs on the Geyser and Caldera clusters by submitting them with the open-source Slurm Workload Manager
Procedures for starting both interactive jobs and batch jobs are described below.
Begin by logging in on Cheyenne.
Compiling code
You will need to compile your code on Geyser or Caldera to run it on these nodes*. See compiling your code below.
Interactive jobs
Using execdav
Run the execdav script/command to start an interactive job. Invoking it without an argument will start an interactive shell on the first available Geyser/Caldera data analysis and visualization (DAV) node. The default wall-clock time is 6 hours.
The execdav command has these optional arguments:
 - -a project_code (defaults to value of DAV_PROJECT)
 - -t time (minutes:seconds or hours:minutes:seconds; defaults to 6 hours)
 - -n number_of_cores (defaults to 1 core: -n 1)
 - -m nG (use this if you want to specify the amount of memory you need to use on the node, from 1 to 900 gigabytes: -m 300G, for example; if you do not specify memory per node, the default memory available is 1.87G per core that you request.)
 - -g gpu_type (gpu_type can be k20, k5000, any or none; defaults to none)
To specify which project code to charge for your CPU time, set environment variable DAV_PROJECT before invoking execdav. For example, DAV_PROJECT=UABC0001.
* * *
Using execgy and execca
The execgy and execca commands execute scripts that start interactive sessions on Geyser and Caldera respectively. A session started with one of these commands uses a single core and has a wall-clock time of 6 hours. Use execdav (see below) if you want to specify different resource needs.
Example with output
cheyenne6:~> execgy
mem =
amount of memory is default
Submitting interactive job to slurm using account SCSG0001 ...
submit cmd is
salloc -C geyser -N 1 -n 1 -t 6:00:00 -p dav --account=SCSG0001 srun --pty ... (shortened for space)
salloc: Pending job allocation 132885
salloc: job 132885 queued and waiting for resources
salloc: job 132885 has been allocated resources
salloc: Granted job allocation 132885
salloc: Waiting for resource configuration
salloc: Nodes geyser10 are ready for job
username@geyser13:~>
To end the session, run exit.
Run execgy -help or execca -help for additional information.
* * *
Using exechpss
The exechpss command is used to initiate HSI and HTAR file transfers. See examples in Managing files with HSI and Using HTAR to transfer files.
* * *
See _URL_ for in-depth Slurm documentation.
Batch jobs
Prepare a batch script by following one of the examples below. The system does not import your Cheyenne environment, so be sure your script loads the software modules that you will need to run the job.
The slurm module is loaded by default on Cheyenne to enable you to run Slurm commands. Include the module in any customized environments that you use if you will be submitting Geyser or Caldera jobs.
Basic Slurm commands
When your script is ready, run sbatch to submit the job.
sbatch script_name
To check on your job's progress, run squeue.
squeue -u $USER
To get a detailed status report, run scontrol show job followed by the job number.
scontrol show job nnn
To kill a job, run scancel with the job number.
scancel nnn
-C option to specify node type
Many user jobs can run on any DAV node and they will spend less time waiting in the queue if the type of node to use is not specified. If you do need to specify a node type for your job, you can use the -C option to set that constraint by including a line like this in your script:
#SBATCH -C geyser
#SBATCH -C caldera
#SBATCH -C pronghorn
You can also combine constraints to specify that the job can run on either caldera or pronghorn. Pronghorn nodes do not have GPUs but are otherwise equivalent to caldera nodes.
#SBATCH -C caldera|pronghorn
In general, minimize resource constraints when possible to decrease the length of time your job waits in the queue.
Wall-clock
The wall-clock limit on these clusters is 24 hours.
Specify the hours your job needs as in the examples below, which use the hours:minutes:seconds format. It can be shortened to minutes:seconds.
Script examples
The examples below show how to create a script for running an MPI job. See these pages for other examples:
Earlier script examples included a source command for initializing the Slurm environment. That command is no longer needed and should be removed from scripts used in the CentOS 7 environment. The first line of the bash scripts for Slurm jobs also has been revised to include the -l option.
For tcsh users
Insert your own project code where indicated and customize other settings as needed for your own job. Do not use the shell's -f option in your first line; it prevents the environment from initializing properly.
#!/bin/tcsh
#SBATCH -J job_name
#SBATCH -n 8
#SBATCH --ntasks-per-node=4
#SBATCH --mem=8G
#SBATCH -t 00:60:00
#SBATCH -A project_code
#SBATCH -p dav
#SBATCH -e job_name.err.%J
#SBATCH -o job_name.out.%J
setenv TMPDIR /glade/scratch/$USER/temp
mkdir -p $TMPDIR
module purge
module load gnu/7.3.0 ncarenv ncarcompilers
module load openmpi
srun ./mpihello
For bash users
Insert your own project code where indicated and customize other settings as needed for your own job.
#!/bin/bash -l
#SBATCH -J job_name
#SBATCH -n 8
#SBATCH --ntasks-per-node=4
#SBATCH --mem=8G
#SBATCH -t 00:60:00
#SBATCH -A project_code
#SBATCH -p dav
#SBATCH -e job_name.err.%J
#SBATCH -o job_name.out.%J
export TMPDIR=/glade/scratch/$USER/temp
mkdir -p $TMPDIR
module purge
module load gnu/7.3.0 ncarenv ncarcompilers
module load openmpi
srun ./mpihello
Compiling your code
You will need to compile your code on Geyser or Caldera to run it on these nodes*.
CISL recommends using the default Intel or GNU compilers for parallel programs. Once you are on a Geyser or Caldera node, load the GNU or Intel compiler and then the openmpi module if you plan to use MPI. Then compile your code as you usually do.
Serial programs can use any compiler.

* Some Caldera nodes use the hostname "pronghorn." Compiling on caldera and pronghorn hosts will generate equivalent executables.

Cleaning Up the Butte Fire Destruction
Calaveras County, CA — The CalRecycle-Calaveras County Butte Fire Debris Removal Project is putting boots to the ground to start removing toxic materials from the devastated areas.
The Department of Toxic Substances Control (DTSC) on Wednesday will deploy teams to remove household hazardous waste, conduct asbestos assessment, and take soil samples in the fire's footprint. The crews are targeting the western portions of Jesus Maria Road and southern portion of Mountain Ranch Road with other areas to follow. The primary focus is to evaluate hazardous waste such as asbestos and remove household hazardous waste such as paints, batteries, electronic wastes, and propane tanks under 30 gallons, according to Calaveras County Director of Environmental Health Jason Boetzer. He shares that nearly 600 properties have already been visited by his office to assess the situation.
To get the toxic waste removed, residents need to sign a "Right of Entry" permit to allow the teams on their property. Boetzer says 250 residents have already signed up and he urges other victims to do the same saying, "A lot of times people don't have enough insurance to pay for the full costs of the cleanup, and then for those people that don't have any insurance, this is fully funded. We want to make sure that individuals are not just loading up the ash and hauling it to a landfill — but that it's handled properly and we're protecting our community during this cleanup process." Boetzer adds that landfills are not taking this debris and anyone caught dumping it illegally could faces legal action. As previously reported, for residents who prefer to do their own cleanup there is a certification process and equipment available through the county.
For question regarding the cleanup, contact the Calaveras County Environmental Health at _PHONE_. Click here for an entry permit.

Here we consider the problem of readout of a digital optical memory, where information is stored by means of the optical properties of the memory cells that are in turn probed by shining a laser beam on them. Interesting features arise in the regime in which the probing light has to be treated quantum mechanically. The maximum rate of reliable readout defines the quantum reading capacity, which is proven to overcome the classical reading capacity-obtained by probing with classical light-in several relevant settings. We consider a model of optical memory in which information is encoded in the (complex-valued) attenuation factor and study the effects on the reading rates of thermal and correlated noise. The latter type of noise arises when the effects of wave diffraction on the probing light beam are taken into account. We discuss the advantages of quantum reading over the classical one and show that the former is substantially more robust than the latter under thermal noise in the regime of low power per pulse.

Address Number Methodology
If you need a physical address for a new structure, call the 9-1-1 Administrative Office at _PHONE_. A "physical address" is also known as an "official 9-1-1 address." When you call the 9-1-1 Administrative Office, make sure you have a physical address for a nearby structure to help us locate your site on the 9-1-1 Map. We do not assign addresses to open land … your structure must at least be staked out so we can identify the approximate location of the center of the structure.
The addressing methodology used in Franklin County was adopted to enable our "first responders" to reach citizens requiring emergency services in the shortest time possible with the least amount of confusion. For public safety reasons, we strive for consistency in our addressing of structures throughout Franklin County. However, there is not complete consistency across the County. For the most part, the cities, towns and villages in the County took responsibility for addressing the structures in their communities and the methodologies used are not the same in many cases.
Road Address Determination
Generally, primary structures in the County are addressed to the road they face unless there is no immediately identifiable access to the structure. Consideration is given to the means of "access" to the structure if access is a substantial distance from the road it faces. The optimal situation is when a structure faces the same road from which the driveway to the structure extends. In the event that a structure is a substantial distance from the road it faces and there is no driveway from that road but there is a driveway from another road, the structure will be addressed to the road with the access.
Address Number Determination
On East/West Roads, odd numbers are on the north side and even numbers are on the south side
On North/South Roads, odd numbers are on the west side and even numbers are on the east side
Address numbers increase as you travel north and as you travel east.
Address numbers decrease as you travel south and as you travel west.
How You Can Help "First Responders"
Make sure your Address Number is displayed so that it can be seen from the road. If your structure is a significant distance from the road, display your Address Number on your mail box or on a sign post at the end of your driveway.

Fireplace ashes can quickly start a fire in and around your home if they are not handled and disposed of properly. Follow these guidelines to help keep your home safe.
- You should always place discarded fireplace ashes in a heavy metal container with a tight fitting metal lid. Approved containers are available commercially. These containers should have a design that keeps the bottom of the container elevated off of surfaces and long handles for carrying. NEVER USE A PAPER BAG, a cardboard box, plastic bucket or a plastic trash bag in the cleaning or cooling process.
- Moisten the ashes and cover the container with the lid. Ashes should be allowed to cool for at least 4 days or longer if possible.
- Never use a vacuum cleaner to pick up ashes.
- Ashes should be kept in a metal container outside, away from the house to cool. Your garage, house, or deck are not suitable locations for ashes to cool.
- Even after four days, great care should be given in selecting a dump site. Wooded areas or areas with combustible materials should always be avoided. NEVER dump fireplace ashes that have not been cooled and checked .
- Garden areas or flower beds are ideal locations to dump cooled fireplace ashes, allowing many nutrients to return to the soil. Please survey the area and evaluate any additional hazards before disposing of your cooled ashes. Make sure all dry leaves have been removed from the area before dumping your ashes in either a garden or flower bed that is away from the house and remember to moisten the area.

The binational migrant initiative was developed to enable those migrant students from Mexico that arrive in the United States, to have access to the same free, appropriate public school education that is provided to other children.
1560 Broadway, Suite 1450
Denver, CO 80202
- Ensure that all binational migrant students have continued access to Education in the U.S. and in Mexico.
- Advocate for and ensure that all binational migrant students have equitable opportunities to learn and meet the high educational standards expected of all students.
- Provide Educators with training, which will allow them to better serve the educational needs of binational migrant students.
- Provide support to parents and families of binational migrant students.
Components of the Binational Migrant Initiative
- Information and Dissemination
The goal of this component is design, develop, and disseminate information to enable educators to meet the educational needs of the binational migrant child, to help them Identify a pedagogical model that specifically addresses the instructional needs of the binational migrant child.
- Transfer Document: Elementary (1-6) Secondary (7-9)
The major focus of the Binational Initiative is to develop, revise and promote the use of the Transfer Document. The Document provides the student his/her grades so that he/she may enroll in school when he/she returns to Mexico. The students credits are accepted, thus, the student is placed appropriately. Parents need to notify the schools when they are going to leave to Mexico so that the school has ample time to complete the document. The student needs to provide a transfer document when he/she returns to the U.S. The Binational Program can retrieve student's grades through a request for transcripts form that has been developed by the Binational Program and has been accepted by the U.S. and Mexico's Binational Initiative.
This document is to be utilized for those students who are departing the United States and are returning to Mexico to enroll in an elementary school.
Transfer document: Elementary School (Primaria), Middle School, (Secundaria)
- Teacher Exchange:
The goal of the teacher exchange is to learn about both educational systems so that we can implement educational programs to better meet the needs of the migrant binational child. The Binational Teacher Exchange is designed to provide a cultural and educational exchange to benefit binational migrant students in the U.S. as well as expertise to educators serving binational students.
These direct experiences among exchange teachers result in a better understanding of the cultural, educational, and linguistic diversity of Mexico and the U.S.
- Culture and Education Resources
Mexico's Secretary of Public Education and the Secretary of Foreign Relations through the Mexican Cultural Center have provided us with 39 sets of content area texts (1-6 grades) that they use in their national curriculum. These books have been distributed to all the local Migrant Ed. programs in Colorado so that they may be used with migratory students or during summer school. Colorado schools have also received information on how to solicit these free instructional content area textbooks.
As part of the Free Textbook Distribution Program, Mexico's Secretary of Public Education and the Secretary of Foreign Relations (through the Mexican Cultural Center) have provided Colorado with resource books for 1-6 grades, that are used for Mexico's national curriculum, to be a resource for binational students.

A Pine can have lightning scars that run down the trunk. Why doesn't an Oak?
 by Cecilia Catron, Tarflower Chapter of the Florida Native Plant Society
(reprinted with permission from the August 2016 issue of Tarpaper)
Pine Scar
 When days are hot, as they have been for the past month, it seems like a sensible idea to lie in or around the pool all day, like a motionless alligator. Curds of bright, white thunderheads rise higher and higher, expanded by the increasing heat. Gradually air pushed from the east and west coasts meets in the middle of the peninsula. By mid-afternoon it becomes charged by the collision of the fronts and summer lightning is created, with or without a storm.
Knotty Oak
Have you ever noticed a stripe spiraling down the trunk of a pine tree where lightning has stripped the outer bark off? You may have also noticed there is no such stripe on the trunk of an oak tree. Oaks and Pines, both dominant here in central Florida, have different lightning survival strategies. Most pine species have long, straight trunks. They are relatively fast-growing with soft wood. Oak trunks on the other hand are often twisted and full of knots. They grow more slowly (except Laurel Oak, Quercus laurifolia) and the wood is very hard, dense, and heavy.
Lightning is attracted to the tallest tree, regardless what species it is. Energy is conducted down the trunk of a typical pine with little to stop it since the cells are constructed in long, continuous rows. Knotty oaks on the other hand do not have such unobstructed cellular highways. When a knot is struck it may explode, but a lightning bolt's energy is spent before it can progress down the trunk, limiting damage. Good planning, oaks. Also a case for organisms that create knots on oaks - part of the ecological give and take. New pines grow relatively quickly to replace trees that are destroyed, which is also a viable strategy.
 Be that as it may, never take shelter under any tree to escape a storm. Especially here in Lightning Alley nature can put on an awesome show, but it's important to remember that a tree may be a target.

Hidden Brain Puzzle #34: Why Ka-Boom! and Ka-Ching! Go Together
Anger can make people want things more, according to a counterintuitive new study which found that when people associate a product with anger, they desire it more.
Henk Aarts of Utrecht University in the Netherlands and his colleagues showed people a number of objects such as pens and mugs. Before the picture of the object appeared on a screen, Aarts subliminally primed his volunteers with an angry, fearful or neutral face. He found that people later reported wanting the object more when they had been primed with the angry face rather than the fearful face. They also exerted more physical effort in acquiring the object in a subsequent test.
Aarts thinks there is an evolutionary reason for the phenomenon: In a statement issued via Psychological Science, where the paper was published, he said, that in competitive environments such as the struggle over a limited food supply or in battle, "If the food does not make you angry or doesn't produce aggression in your system, you may starve and lose the battle."
In a recent puzzle posted on the Hidden Brain's Facebook page, I asked:
You have to decide whether to buy something. You are most likely to make the purchase when
A) You are angry
B) You are fearful
C) You are angry and fearful
D) You are neither angry nor fearful
The correct answer is A.
Does this theory explain the behavior of all those angry couples we see in movies who patch up fights by having sex?

Parenscript Object System

This article is out of date. See's recent version.
The Parenscript Object System (PSOS) is a facility for object-oriented programming in Parenscript using the same style and techniques as the Common Lisp Object System. It consists of a set of macros in lisp and a runtime environment in Parenscript.
In the Javascript world, the Parenscript Object System is probably the most sophisticated method for object-oriented programming. It is different from object-oriented systems that use the message-passing paradigm (like Java, C++) in a few ways. If you are not lisp-aware but ambitious, you can read chapters 15 and 16 of Practical Common Lisp, which discusses the Common Lisp Object system.
PSOS is designed to be similar CLOS. However, PSOS should not be everything that CLOS is. It should be a fairly small library (and currently compiles to about 10k in Javascript), for example. There are also differences between Javascript and Lisp, especially Javascript's lack of Lisp-like symbols.
Multiple inheritance, generic functions, and basic method combination are currently implemented.
1. Different classes of people
The following is a simple example that demonstrates how PSOS can be used to obtain simple class inheritence. This works in much the same way as other javascript class systems that are out there already.
(defclass person () () (:documentation "Any old person."))
(defclass citizen (person) () (:documentation "A person who votes."))
(defclass politician (citizen) () (:documentation "A person in public office."))
(defgeneric discuss-environment (individual))
(defmethod discuss-environment ((individual citizen))
(defmethod discuss-enviornment ((individual politician))
 (alert "The environment is an important issue, but so is the War on Terror."))
(dicuss-environment (new politician)) ; alerts "the environment is..."
2. An event-handling system
This is a practical example that demonstrates a way to use generic functions and classes to implement an event-handling system.
;;; Event Handling ;;;
(defvar global-event-table (create))
(defclass event ()
 ((origin) (description))
 (:documentation "Primitive event class for event observation. Custom
event classes are created that subclass the abstract event class. These are dispatched
by calling (make-instance some-event-class (create :origin origin...))."))
(defclass event-emitter () () (:documentation "Subclasses of this can emit events."))
(defun event-handler-fits? (handler ev)
 (return (is-subclass-of handler.event-class (class-of ev))))
(defmethod initialize-instance :after ((ev event))
 (event-fired (get-origin ev) ev))
(defmethod register-event-handler ((on-obj event-emitter) event-class handler-func)
 (let ((obj-observers (defaultf on-obj.event-handlers (array))))
 (obj-observers.push (create :func handler-func :event-class event-class))))
(defgeneric event-fired (within-obj ev)
 (:documentation "Called when an event was fired within the given object.
For example, if a button is clicked within a page, then the event will eventually fire
for the page object with the given event."))
(defmethod event-fired ((within-obj event-emitter) ev)
 (let ((handlers (and within-obj.event-handlers
 (lambda (handler)
 (return (event-handler-fits? handler ev)))))))
 (when handlers
 (dolist (handler handlers)
 (handler.func ev))))
(defmethod event-fired ((within-obj general-sail) ev)
 (let ((parent (parent-sail within-obj)))
 (when parent
 (event-fired parent ev))))

Outstanding issues
PSOS works well as a class system now, but certain ideas have not been hammered out yet. In particular, dealing with slot definitions is currently done via a compile-time expansion rather than letting the Javascript runtime environment initiate slots. This is primarily due to what I do know about scoping in Javascript. Suggestions or comments about slot definitions, or PSOS in general, are welcome. -red 10:39, 16 January 2007 (UTC)
