Sometimes, it can be hard to tell if it's time for a new roof - most homeowners don't actually want to install new roofs. However, a roof replacement can not only keep your family safe from the elements, but it can also improve the curb appeal and value of your home. It's a good investment to make whether you're intending on staying in your home for years to come, or if you're planning on selling in the near future.
Here at Preferred Home Improvement, we have over 30 years of experience specializing in roof replacement services for local homeowners. We work with many materials to give your home the best chance at ultimate protection. If you're looking to install a beautiful and lasting roof, you've come to the right place. Call Preferred Home Improvement and we will promptly come out to your home or business to meet with you. We will diagnose the problem and suggest a solution only using only the best roofing materials.
Asphalt shingles are the most popular choice for roofing because they provide a durable roof for less money than any other roofing material. Asphalt shingles also come in a variety of styles and colors, so they can match almost any home. Threetab shingles are the most commonly-installed asphalt shingle because of their classic design and affordable cost. If you like the genuine wood-shake look, architectural shingles are a great option.
Preferred Home Improvement offers a wide range of roofing shingle options from leading manufacturers. From cost-effective three-tab shingles to high-performance specialty products, we can help you choose the right shingle for your home and budget.
Metal roofs provide energy savings, beauty, and protection for your home that can last a lifetime. Residential metal roofs are available in a wide variety of design to complement any style home. Offered in a rainbow of colors, your metal roof can be a traditional vertical seam profile, or be manufactured to resemble wood shake, slate, shingles or clay tiles.
 Conventional roofing products, including asphalt shingles, contribute an estimated 20 billion pounds of waste to U.S. landfills annually, whereas metal roofs can often be installed over an existing roof, eliminating the cost and eco-impact of tear-off and disposal.
Many residential metal roofs now utilize reflective pigment technology, which results in overall home energy efficiency, and lower utility bills. In addition, all metal roofs are made from 30-60% recycled material.
While your neighbors may re-roof their home many times, a high-quality metal roof will likely be the last roof you'll ever need. Resistant to cracking, shrinking and eroding, metal roofing systems can also withstand extreme weather conditions including heavy snow loads, hail storms and wildfires.
A metal roof will not increase the likelihood of lightning striking your home. However, if your home were hit by lightning, your metal roof would disperse the energy safely throughout the structure. Since metal roofing isn't combustible or flammable, it's a low risk and desirable roofing option where severe weather is concerned, especially for lightning.
A common misconception is that a metal roof will be noisier than other types of roofing. When installed with solid sheathing, a metal roof on your home will actually silence noise from rain, hail and bad weather, many times much better than other roofing materials.
Today's metal roofing systems are built to last. Steel metal roofing has a "metallic coating" made of either zinc or a combination of zinc and aluminum. This metallic coating prevents rust from forming and is bonded to the steel at the factory. Paint is then applied over the metallic coating to provide the long-lasting color homeowners desire
In most cases, a metal roof can withstand decades of abuse from extreme weather like hail, high winds, and heavy snow. Today's systems also have a 150-mph wind rating (equal to an F2 tornado), meaning your metal roof is also safe from wind gusts that can accompany hail storms.
Many people think you can't (or shouldn't) walk on a metal roof, but the truth is that you can safely walk any metal roof without damaging it. Before you walk your roof, however, we recommend you talk to your installed or roof manufacturer first. They will have the details on how to walk the particular roof you have, based on the style you chose and your roof pitch.

flibs/m_fileunit(n) 1.0 "flibs"
flibs/m_fileunit - Manage file units
TABLE OF CONTENTS
SYNOPSIS
DESCRIPTION
OVERVIEW
ROUTINES
TODO
COPYRIGHT
The component m_fileunit provides services to manage fortran file units.
The function fileunit_getfreeunit returns an integer representing
a fortran unit which is available for opening a file.
The typical use of this function is to manage the files dynamically,
without any database of file units in the library/software.
In the following example, one opens a file with a dynamical
file unit.
| |
integer :: fileunit
fileunit = fileunit_getfreeunit ()
open ( unit = fileunit , file = "data.txt" )
[lb]etc...[rb]
|
If several files are to be opened, the "fileunit_getfreeunit"
method has to be inserted between the "open" statements.
This is because two consecutive calls to "fileunit_getfreeunit"
will return the same integer, as expected : if a unit is available
the first time, it will also be available the second time.
In the following example, several files are opened and connected
to several files.
| |
integer :: fileunit1
integer :: fileunit2
fileunit1 = fileunit_getfreeunit ()
open ( unit = fileunit1 , file = "data.txt" )
fileunit2 = fileunit_getfreeunit ()
open ( unit = fileunit2 , file = "data2.txt" )
[lb]etc...[rb]
|
In a large fortran software, it may be difficult to see if some
bug has been introduced in the file management, especially
when the software is the composition of several libraries.
The subroutines fileunit_getallopen , fileunit_closeallopen ,
fileunit_report , fileunit_displayopen allow to manage for
the units currently used in the software.
The fileunit_getallopen returns an array of integers which
contains all the currently opened units. The fileunit_closeallopen
subroutine close all currently opened units. The fileunit_report
displays a full report about a given unit number by using the
"inquire" fortran intrinsic statement.
- fileunit_getallopen ( nbunits , units )
-
- integer, intent ( out ) :: nbunits
-
- integer , dimension(:) , pointer :: units
-
Computes an array of integers made of all currently opened units.
On output, nbunits is the number of opened units and
units ( iunit ) is the unit number for the opened unit #iunit
with 1<= iunit <= nbunits.
- fileunit_displayopen ( reportunitnumber )
-
- integer, intent ( in ) :: reportunitnumber
-
Writes on unit unitnumber the full list of opened units and their associated
filenames.
- fileunit_report ( reportunitnumber iunit)
-
- integer, intent ( in ) :: reportunitnumber
-
- integer, intent ( in ) :: iunit
-
Compute report about logical unit iunit and write it on
unit unitnumber. Note : All possible features of the "inquire" intrinsic are used.
- fileunit_closeallopen ( )
-
Close all currently opened units.
- fileunit_getfreeunit ( ) result ( freeunit )
-
- integer :: freeunit
-
Returns a free fortran unit freeunit as an integer between 1 and FILEUNIT_MAX_UNIT_NUMBER,
representing a free FORTRAN logical unit.
If no free unit can be found, generates an error.
Note that fileunit_getfreeunit assumes that units 5 and 6
are special, and will never return those values.
Original Author : John Burkardt
- fileunit_set_stoponerror ( stoponerror)
-
- integer :: freeunit
-
Configure the behaviour of the component whenever an
error is met.
If stoponerror is true, then the execution stops if an error is encountered.
If stoponerror is false, then the execution continues if an error is encountered.
In both cases, a message is displayed on standard output.
- allow to "lock" a collection of logical units, so that an
external library which may use constant units can be linked.
- allow to "unlock" one unit, or all units at once.

Training with Curriculum Learning
Sample Environment
Imagine a task in which an agent needs to scale a wall to arrive at a goal. The starting point when training an agent to accomplish this task will be a random policy. That starting policy will have the agent running in circles, and will likely never, or very rarely scale the wall properly to the achieve the reward. If we start with a simpler task, such as moving toward an unobstructed goal, then the agent can easily learn to accomplish the task. From there, we can slowly add to the difficulty of the task by increasing the size of the wall, until the agent can complete the initially near-impossible task of scaling the wall. We are including just such an environment with ML-Agents 0.2, called Wall Area.
Demonstration of a curriculum training scenario in which a progressively taller wall obstructs the path to the goal.
To see this in action, observe the two learning curves below. Each displays the reward over time for an agent trained using PPO with the same set of training hyperparameters. The difference is that the agent on the left was trained using the full-height wall version of the task, and the right agent was trained using the curriculum version of the task. As you can see, without using curriculum learning the agent has a lot of difficulty. We think that by using well-crafted curricula, agents trained using reinforcement learning will be able to accomplish tasks otherwise much more difficult.
How-To
So how does it work? In order to define a curriculum, the first step is to decide which
parameters of the environment will vary. In the case of the Wall Area environment, what
varies is the height of the wall. We can define this as a reset parameter in the Academy
object of our scene, and by doing so it becomes adjustable via the Python API. Rather
than adjusting it by hand, we then create a simple JSON file which describes the
structure of the curriculum. Within it we can set at what points in the training process
our wall height will change, either based on the percentage of training steps which have
taken place, or what the average reward the agent has received in the recent past is.
Once these are in place, we simply launch ppo.py using the –curriculum-file
flag to
point to the JSON file, and PPO we will train using Curriculum Learning. Of course we can
then keep track of the current lesson and progress via TensorBoard.

AFCON 2021 Qualifiers: Ghana coach Kwesi Appiah hails impact of deputy CK Akonnor in victory over South Africa
Head coach of the Black Stars Kwesi Appiah has hailed the influence of his deputy CK Akonnor in team's win over South Africa on Thursday.
Akonnor, 45, replaced Ibrahim Tanko as deputy trainer late last month for the four-time Africa champions ahead of the two qualifying matches.
The former Hearts of Oak and Asante Kotoko gaffer was on the bench when the Black Stars brought smiles to the faces of Ghanaians following their 2-0 win over South Africa in the first match of the 2021 Africa Cup of Nations qualifier against South Africa at the Cape Coast Sports Stadium.
Goals from either half by Thomas Partey and substitute Kudus Mohammed were enough for the four-time Africa champions to see off the Bafana Bafana.
Speaking at his post-match presser, coach Appiah shared the glory with his assistant trainer CK Akonnor whom he believes did much of the work during the match.
"If you a head coach and you're out there sometimes your mind goes somewhere, sometimes you must be looking at three or four players who are not playing well so this is where you need your assistant to assess the game because he knows the game plan and he knows our players so he might sit down and come to you and let you know that coach...why can't you look at this because it's a problem for us."
"So it is important to link up well with your assistant so that anytime he has to sit down quietly and assess the game and give information as to what to do.

-
1. (4 pts) Before you come to your first discussion section (lab), PLEASE visit this website and create your College of Engineering account (unless you already have one). Then write your College of Engineering username below. (DO NOT WRITE YOUR PASSWORD!!!!!  Just your username!)
Website: https://accounts.engr.ucsb.edu/create. Write your username here:
2. (1 pt) What is the size of the smallest data item in main memory that has a memory address? You may provide your answer in bits or bytes.
3. (5 pts) The book talks about the five important hardware components of a computer i) input devices ii) output devices iii) processor iv) main memory and v) secondary memory. It also talks about two important pieces of software: compilers and operating systems. Which of the above is primarily responsible for each of the following tasks? Write 'none' if none of the options apply.
i. Converts a program from a high-level language to machine language.
ii. Executes a program stored in main memory.
iii. Allocates the computer's resources to the different tasks that the computer must accomplish.
iv. Stores a program while it is being executed.
v. Converts a program from one high-level language to another high-level language.
4. (2 pts) Not including any comments that may appear, what are the first two lines that typically begin a C++ program that is going to either output on the screen, and/or read input from the keyboard?
5. (4 pts) As you discovered when you read the textbook, for the most basic kind of input and output, C++ uses two words, and two symbols, along with variables and quoted strings. Unlike in some other languages (e.g. Python), quoted strings must always use double quote marks `"like this"`, never single quotes `'like this'`. (Single quotes are used for another purpose in C++.) Inside a quoted string, `\n` means "newline". Quoted strings can only be output, while the value of a variable can be either output to the screen, or read in from the keyboard. Variable names are not put inside quotation marks. Also remember that every line of C++ that does input or output must end in a semicolon.
Assuming the variable `int age;` has already been declared and initialized with a value, write a C++ statement that will print out `My age is: ` followed by the value of the variable `age`, followed by a newline?. (For full credit, be sure to end your line with a semicolon.)
6. (4 pts) The textbook describes C++11 on p.27. Briefly, what is C++11? (A one sentence answer is good enough. Note that if your textbook doesn't describe C++11 on p. 27, then you may have the wrong edition. You need the ninth or tenth edition.)

ATLL - Avoid Too Long Lines
According to Sun Code Conventions for Java, lines longer than 80 characters should be avoided, since they're not handled well by many terminals and tools.

Generate & Submit Task
The most efficient way to use Parallec is by reviewing the example codes.
APIs on Request Generation
First lets check on the ones that are protocol independent.
- setTargetHostsFrom*() is critical to set the target hosts, you may check the details on the following section
- setConcurrency() is important when you want to change how fast/slow to send the requests.
Details on configs please check here.
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| setTargetHostsFrom*() | Required | No default. Must be set. | To set target host list from a string, list, line by lien text, jsonpath, and cms query from local or remote. |
| setProtocol() | Optional | HTTP | Normally we do not need to set this. When you do prepare*() it is already set. When it is HTTPS. you will need to set it |
| setConcurrency() | Optional | concurrencyDefault (1000) | The concurrency level. You may send 100,000 requests but send it very slowly. |
| setConfig() | Optional | default values | Configs about various timeout, whether to auto save responses. whether to enable the response. This can set all the task level over writable configurations. |
| setEnableCapacityAware TaskScheduler() | Optional | false: not enabled | After enabled, can accommodate the traffic. |
| async() | Optional | false, default to sync mode. | To run the parallel task async . You may check if the task is completed later. |
Capacity aware scheduler
When enabled, task will be pushed to the wait queue instead of immediate execution. A daemon thread (by newSingleThreadScheduledExecutor) will check every 0.5 second if there is capacity to run a task from the wait queue.
This is useful to protect our application when there are multiple concurrent ParallelTasks, and each has high currency requirement.
By default this scheduler is disabled. This is unnecessary unless there are high load or tasks are submitted without our control (e.g. serve as a server).
APIs on Response Handling
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| handleInWorker() handleInManager() | Optional | HandleInManager() | Please check the Response Handler Location below for details. |
| setResponseContext() | Optional | An empty hashmap | Useful when need to pass arbitrary objects from/to the response handler: e.g. pass in an Elastic Search or Kafka Client, or a hashmap to store / process / aggregate the responses. |
| execute() | Required | n/a | Key function to execute the parallel task. It will first do a validation on required data before the execution. |
| setAutoSaveLogToLocal() | Optional | False | Will auto save logs to the local file system. The logs by default are written to path "userdata/task/logs" folder. Note that it is user's responsibility to clearn these logs. |
| setSaveResponseToTask() | Optional | False | If true, will save response to the ParallelTask object. In default, only status code is saved. |
Response Handler Location
This is about when to call the user defined response handler's onComplete() function.
- Handler in manager (default): Call response handler in manager (in a sequence after aggregation) Default mode. In this mode, will trigger the user defined response hander after response is passed back from worker to manager. This is the default mode. Be cautious on using long blocking operation in the handler onComplete() function. Because a long operation may block the whole flow because each response will need to go through here.
- Handler in worker: Call response handler in operation worker (in parallel before aggregation). Handle the user defined onComplete() function in worker before aggregation (handle in parallel). Be cautious on concurrency / lock control if save the response to a common data store. Also when you define the concurrency level, take into account of the time needed to hander the response.
Set Target Hosts
Parallec provide flexible way to input multiple target hosts from list, string, line by line text, json path, cms query from local or remote urls.
Check the following .setTargetHosts*() functions to set the target hosts.
From Java List
.setTargetHostsFromList(Arrays.asList("www.jeffpei.com", "www.restcommander.com"));
From Java String
From a single string as separate by whitespace.
.setTargetHostsFromString("www.jeffpei.com www.restcommander.com");
From Line by Line Text
From a local file containing host names line by line. Relative or absolute paths are both supported.
.setTargetHostsFromLineByLineText("userdata/sample_target_hosts_top100_old.txt",
HostsSourceType.LOCAL_FILE)
Also, you can set target hosts from such a file from a web URL. (This will use the apache server)
.setTargetHostsFromLineByLineText("http://www.restcommander.com/docs/sample_target_hosts_top100.txt",
HostsSourceType.URL)
From Json Path
JsonPath is useful to extract host name list from a json file
Here is a sample json file that contains host names.
As long as seperate by whitespace
String jsonPath = "$.sample.small-target-hosts[*].hostName";
.setTargetHostsFromJsonPath(jsonPath,
"http://parallec.github.io/userdata/sample_target_hosts_json_path.json", HostsSourceType.URL);
You may also load such jsons from local file system too.
From YiDB/CMS Query
YiDB a.k.a CMS (Configuration Manage System internally) may store the cloud topology information.
Here is a sample CMS Query Result that contains host names.
Parallec will auto load target hosts from CMS query and handles paginations for you.
public final String URL_CMS_QUERY_MULTI_PAGE = "http://parallec.github.io/cms/repositories/cmsdb/branches/main/query/sample_cms_query_results_multi_page_1.json";
.setTargetHostsFromCmsQueryUrl(URL_CMS_QUERY_MULTI_PAGE);
Timeout in URLs
ParallecGlobalConfig defines the timeout using the remote URL to get target hosts. One may change it before usage.
/** The url connection connect timeout millis. Used when load target host from URL/CMS*/
public static int urlConnectionConnectTimeoutMillis = 6000;
/** The url connection read timeout millis. Used when load target host from URL/CMS*/
public static int urlConnectionReadTimeoutMillis = 15000;
APIs on HTTP
Most of the APIs to set HTTP properties are named with setHttp*(), except for the setAsyncHttpClient() which overwrite the asyncHttpClient used.
Set HTTP Method, URL and Protocol
- prepareHttp*() will set the url and HTTP Method. e.g., prepareHttpGet("/index.html") means to conduct HTTP GET http://[targethost]:/index.html
- When need to do HTTPS, will do setProtocol(RequestProtocol.HTTPS)
Set HTTP Header
Here is the sample code to set HTTP Header with help of ParallecHeader.
.setHttpHeaders(new ParallecHeader().addPair("content-type", "application/json").addPair("key", "value"))
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| prepareHttp*() | Required | n/a | This is the starting point. Will will set the HttpMethod (e.g. GET/POST/PUT/DELETE) and the url. |
| setHttpHeaders() | Optional | empty | Add headers using ParallecHeader. Check example above. |
| setHttpEntityBody() | Optional | empty | For example, a POST body for the request. |
| setHttpPort() | Optional | port 80 | Set HTTP port. |
| setHttpPoller Processor() | Optional | empty | Sets the HTTP poller processor to handle Async API, will auto enable the pollable mode with this call. Details check here. |
| setAsyncHttpClient() | Optional | Embed fast one from the store | You may overwrite the client to your customized one for each task. The default one is the embed fast one from HttpClientStore. |
| saveResponseHeaders() | Optional | false | Save HTTP response headers. Please check ResponseHeaderMeta and the example. |
APIs on SSH
The APIs to set SSH properties are named with setSsh*().
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| prepareSsh() | Required | n/a | Starting point of ssh. Set protocol as SSH. |
| setSsh CommandLine() | Required | n/a | The command flow you would like to execute. |
| setSshPort() | Optional | 22 | The SSH Port. |
| setSsh UserName() | Required | n/a | User name when login |
| setSsh LoginType() | Optional | empty | The login is either key or password based. |
| setSshPassword() | Optional | n/a | The ssh login password. Will also auto set the login type to password |
| setSsh Connection TimeoutMillis() | Optional | 5000 millisec | Connection timeout. Default to 5000 millisec in global config. |
| setSshPrivKey RelativePath() | Optional | n/a | Note that this path must be relative to the project e.g. "userdata/fake-privkey.txt". This API assumes no passphrase for the private key. Will also auto set the login type to key based. |
| setSshPrivKey RelativePath WtihPassphrase() | Optional | n/a | Note that this path must be relative to the project. argument include a private key path with passphrase. Will also auto set the login type to key based. |
APIs on PING
The APIs to set Ping properties are named with setPing*().
Details of the two modes of implementations can be found in PingProvider.java
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| preparePing() | Required | n/a | Starting point of ssh. Set protocol as "Ping". |
| setPingMode() | Optional | InetAddress | Process or InetAddress based. Default as InetAddress mode. InetAddress requires Root privilege. |
| setPing TimeoutMillis() | Optional | 500 | The timeout in milliseconds. |
| setPing NumRetries() | Optional | 1 | The number of retries. |
APIs on TCP
The APIs to set TCP properties are named with setTcp*().
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| prepareTcp() | Required | n/a | Starting point of TCP request. Set protocol as "TCP" and the request string. |
| setTcpPort() | Required | n/a | A port number server listens on. |
| setTcp Connect TimeoutMillis() | Optional | use default 2000 | The connection timeout in milliseconds. |
| setTcpIdle TimeoutSec() | Optional | use default 5 | The idle timeout for the channel to close the connection. |
| setTcp ChannelFactory() | Optional | use the default one | If not set, will use the default one in TcpSshPingResourceStore. |
APIs on UDP
The APIs to set UDP properties are named with setUdp*().
| API | Required | Default If Not Set | Details |
|---|---|---|---|
| prepareUdp() | Required | n/a | Starting point of UDP request. Set protocol as "UDP" and the request string. |
| setUdpPort() | Required | n/a | A port number server listens on. |
| setUdp IdleTimeoutSec() | Optional | use default 2 | The idle timeout for the channel to close the connection. Similar to a read timeout. |
APIs on Variable Replacement for Heterogeneous Requests
When the protocol is HTTP, the request's entity body, request URL, and also the header part can be putting as a template with variable denoted with "$VariableName".
More complex replacement samples are available in the test cases.
Different requests to different target hosts
Here is the example of hitting 3 different APIs on 3 different servers. $JOB_ID is the variable being replaced. The API to use is setReplacementVarMapNodeSpecific(). Complete sample code is here.
- http://www.parallec.io/job_a.html
- http://www.jeffpei.com/job_b.html
- http://www.restsuperman.com/job_c.html
Map<String, StrStrMap> replacementVarMapNodeSpecific = new HashMap<String, StrStrMap>();
replacementVarMapNodeSpecific.put("www.parallec.io",
new StrStrMap().addPair("JOB_ID", "job_a"));
replacementVarMapNodeSpecific.put("www.jeffpei.com",
new StrStrMap().addPair("JOB_ID", "job_b"));
replacementVarMapNodeSpecific.put("www.restcommander.com",
new StrStrMap().addPair("JOB_ID", "job_c"));
pc.prepareHttpGet("/$JOB_ID.html")
.setTargetHostsFromString(
"www.parallec.io www.jeffpei.com www.restcommander.com")
.setReplacementVarMapNodeSpecific(replacementVarMapNodeSpecific)
.execute(new ParallecResponseHandler() {...}...
Different requests to the same target host
Here is the example of hitting 2 different APIs to the same target host. $ZIP is the variable being replaced. setReplaceVarMapToSingleTargetSingleVar(String variable, List
- http://www.parallec.io/userdata/sample_weather_48824.txt
- http://www.parallec.io/userdata/sample_weather_95037.txt
pc.prepareHttpGet("/userdata/sample_weather_$ZIP.txt")
.setReplaceVarMapToSingleTargetSingleVar("ZIP",
Arrays.asList("95037","48824"), "www.parallec.io")
.setResponseContext(responseContext)
.execute(new ParallecResponseHandler() {...}...
Regular Expression Response Filter
When defining the response handler, we provide a very simple regular expression based filter class FilterRegex to extract strings.
For example: with ResponseOnSingleTask res, we can apply parse on the response body.
String extractedString = new FilterRegex(
".*JobProgress	\\s*(.*?)	.*")
.filter(res.getResponseContent());
Async APIs and Auto Progress Polling
Motivation
In many RESTful services today, a job such as "create compute", "download package" may take indefinite amount of time. And these APIs are normally designed to be asynchronus. They immediately return a Job ID, by which you can poll for the job progress and check status. To achieve job level concurrency, it is essential to define a poller, which describes how to poll progress and when to stop as below. Here are the attributes in a poller. Please refer to the javadoc for more details.
- The regex to get jobId
- The regex to get the progress
- The progress polling API (a template with the jobId)
- The job completion regex
- The job failure regex
- The polling interval
Sample Server
Please check this example for complete code. If we have a job submission API that return a job ID, as in this sample server
//submit job
HTTP POST: /submitJob return: {"status": "/status/01218499-a5fe-47cf-a0a8-8e9b106c5219", "progress": 0}
//poll progress
HTTP GET: /status/{JobID}
Sample Poller
// Initialize the poller
String pollerType = "CronusAgentPoller";
String successRegex = ".*\"progress\"\\s*:\\s*(100).*}";
String failureRegex = ".*\"error\"\\s*:\\s*(.*).*}";
String jobIdRegex = ".*\"/status/(.*?)\".*";
String progressRegex = ".*\"progress\"\\s*:\\s*([0-9]*).*}";
int progressStuckTimeoutSeconds = 600;
int maxPollError = 5;
long pollIntervalMillis = 2000L;
String jobIdPlaceHolder = "$JOB_ID";
String pollerRequestTemplate = "/status/" + jobIdPlaceHolder;
HttpPollerProcessor httpPollerProcessor = new HttpPollerProcessor(
pollerType, successRegex, failureRegex, jobIdRegex,
progressRegex, progressStuckTimeoutSeconds, pollIntervalMillis,
pollerRequestTemplate, jobIdPlaceHolder, maxPollError);
To enable the poller defined above, simply call .setHttpPollerProcessor(httpPollerProcessor) when building the task. Parallec will then automatically poll the task progress until it is successful or failure for you, and enable the job level concurrency.

Rockport is representing ACI ACRIS in the Smart Airport Catalyst as part of the
Digital Business Marketplace
initiative by TM Forum.
We have integrated the relevant components of the ACRIS Semantic Model
with similar elements from TM Forum’s Information Framework within a digital twin of an airport to enable new services.
September 2022 Update: Bob Logan presented and demonstrated our airport digital twin at the Digital Transformation World conference and exhibition in Copenhagen in September 2022.
PRESS RELEASE. Click here to view the TM Forum DTW Smart Airports - Enabling All Travelers to be VIPs press release.
Rockport Software is proud to participate in the Fly2Plan project as part of a cross-industry consortium.
The consortium, led by Heathrow Airport, includes operational experts from airports, airlines and air traffic management, as well as technology and academic organisations.
Emerging and future models of airspace use, for example drones and unmanned air taxis arriving and departing from an airport, and from many other locations, will
require a dramatic increase in the sharing and exchage of aviation information and may require new information models and standards.
The Fly2Plan project looks to support future information exchange requirements of UK airspace by building a blockchain-based system
to facilitate the trusted exchange of aviation information in a secure and scalable manner.
The Airports Council International (ACI) ACRIS Semantic Model provides a consistent
and integrated view of airports and the wider aviation ecosystem and is ideally placed to support this project for the demanding requirements of current and future airspace operators.
Rockport is an active member of the Airports Council International (ACI) working group responsible for the definition of standards
for information exchange, known as the ACRIS initiative (Airport Community Recommended Information Services). Rockport have contributed to many ACRIS initiatives including significant involvement in the development of the ACI Semantic Model, using Sparx Systems Enterprise Architect. Rockport host the Semantic Model on our cloud platform to support continuous development of the Semantic Model by airports around the world Rockport has a contract with ACI World to provide all ACRIS Semantic Model support services, including maintaining the ACRIS website. Please contact Rockport to find out how to get involved with, and benefit from, these initiatives.
If you would like to request access to the ACI Semantic Model, please contact us. Rockport actively participates in the IATA/ACI Modern Messaging initiative (Baggage Information Exchange).
This initiative has developed a new standard for bag messaging that will revolutionise the world of Baggage Operations.
The new standard, known as Recommended Practice 1755, built using the IATA AIDM (Airline Industry Data Model), will replace RP 1745 in due course.
This will greatly facilitate the reduction in misconnected bags.
It will also support the new IATA Resolution 753 that requires airlines to provide certain mandatory information to passengers regarding the location of their bags. Rockport Software can support your involvement with and adoption of the new bag messaging standard. We can offer a hosted broker service for organisations of any size.
Rockport Software host the ACI Semantic Model on behalf of Airports Council International (ACI). The ACRIS Semantic Model is available for online access for registered users in support of active ACRIS projects. The change management process for the Semantic Model is administered using our JIRA helpdesk for registered users. If you would like more information about, or to request access to, the ACI Semantic Model, please contact us. Rockport Software have developed the IATA/ACI Modern Messaging Baggage Testbed and manage and host the service on our cloud platform. The testbed provides a platform against which new implementations of airport/airline/vendor broker nodes can connect and conduct integration tests.
The testbed is an scalable MQTT broker supporting a standard set of tests defined in the RP1755 Implementation Guide. If you would like more information about this service, please contact Rockport. Please contact Rockport if you are interested in these types of projects.Current Projects

Callum Smith defends WBA ‘super’ belt but toils against gutsy John Ryder
by FSA EditorIt was not pretty but ultimately Callum Smith did enough to overcome a game John Ryder and defend his WBA ‘super’ middleweight world title.
Callum Smith scored a unanimous decision victory to retain his WBA ‘super’ middleweight world title but was made to toil by a gallant John Ryder in Liverpool.
The home city fighter was an overwhelming favourite against Londoner Ryder but was troubled by the work rate of his tireless opponent, who gave up plenty in height and reach.
However, unbeaten Smith moved to 27-0-0 with the judges scoring it 117-111, 116-112 and 116-112 in his favour having clearly decided he landed the cleaner punches.
It was hardly the statement performance Smith would have wanted as he chases career-defining fights with the likes of Saul ‘Canelo’ Alvarez or Billy Joe Saunders, but a below-par showing here may actually make those bouts easier to make.
“I knew he was a tough fighter, I knew it was a tough fight,” Smith said after the bout. “It wasn’t the best performance from myself, but I was due a bad one.
“I’m a perfectionist and I always want to do the best as possible. Listen, I know how good I am, how good I can be.
“I want the best names in the division. The fear brings out the best performance in myself.”
Ryder vastly outperformed expectations and the fact there was a smattering of boos amid a partisan home crowd after the scores were read out told a story in itself.
After an uneventful couple of opening rounds, Smith began to up the work rate and although the man nicknamed ‘Mundo’ sustained a cut in the fourth, some clean hooks in the fifth had Ryder in trouble for the first time.
A sharp right and some thudding strikes in the sixth suggested Smith’s class was about to tell, but Ryder’s relentless grit was causing the champion issues.
Good work on the ropes from close range would have had Ryder dreaming of an upset and the underdog upped the ante when trainer Tony Sims warned him Smith may try and steal it with the jab.
Both men landed big hooks in a brilliant final round but ultimately it was controversially deemed Smith had done enough to control the fight.

People at very high risk from coronavirus (extremely vunerable)
If you're at very high risk (extremely vulnerable) from coronavirus (COVID-19), there are extra steps you're advised to take to protect yourself.
These extra steps are called shielding.
This advice is for people who have received a letter from the NHS saying they're at very high risk.
If you're not sure whether you're at very high risk, see who's at higher risk from coronavirus.
How to protect yourself if you're at very high risk
It's currently recommended you follow this advice until at least the end of June 2020.
Do
-
stay at home at all times – do not leave your home to buy food, collect medicine or exercise
-
stay at least 2 metres (3 steps) away from other people in your home as much as possible
-
get food and medicine delivered and left outside your door – ask friends and family to help or register to get coronavirus support on GOV.UK if you need it
-
prepare a hospital bag, including a list of the medicines you're taking, in case you need to go into hospital
-
wash your hands with soap and water often – do this for at least 20 seconds
-
make sure anyone who comes into your home washes their hands with soap and water for 20 seconds
-
use hand sanitiser gel if soap and water are not available
-
clean objects and surfaces you touch often (such as door handles, kettles and phones) using your regular cleaning products
-
clean a shared bathroom each time you use it, for example by wiping the surfaces you have touched
Don't
-
do not have visitors in your home, including friends and family, unless they're providing essential care
-
do not stop taking any prescription medicines without speaking to your doctor
If you live with someone who is at very high risk, see our advice about living with someone who is at very high risk from coronavirus.
Register for support
If you've been told you're at very high risk from coronavirus, you can register for support, such as getting food delivered to your home.
It's a good idea to do this even if you do not need support right now.
You can either:
- register for coronavirus support on GOV.UK
- call 0800 028 8327 to register
You'll need your NHS number to register. You can find this on the letter you received telling you that you're at high risk, or on any prescriptions.

How to look after your health and wellbeing
Staying at home and reducing contact with other people can be difficult.
There are things you can try to help you stay well:
- stay in touch with family and friends over the phone or on social media
- spend time doing things you enjoy, such as reading, cooking, indoor hobbies, listening to the radio or watching TV
- do light exercise at home
- spend time with the windows open to let in fresh air
- spend time in your garden or on your doorstep, if possible, but stay at least 2 metres (3 steps) away from other people
- consider taking 10 micrograms of vitamin D each day if you’re indoors most of the day – this is to keep your bones and muscles healthy

Code Documentation¶
Hottop Interface¶
This is the primary class that you will interact with when building applications for the Hottop roaster. This class will automatically spawn a threaded instance of the control process which will handle the core of the operations against the roaster.
-
class
pyhottop.pyhottop.
Hottop
[source]¶ Object to interact and control the hottop roaster.
Returns: Hottop instance -
_autodiscover_usb
()[source]¶ Attempt to find the serial adapter for the hottop.
This will loop over the USB serial interfaces looking for a connection that appears to match the naming convention of the Hottop roaster.
Returns: string
-
_callback
(data)[source]¶ Processor callback to clean-up stream data.
This function provides a hook into the output stream of data from the controller processing thread. Hottop readings are saved into a local class variable for later saving. If the user has defined a callback, it will be called within this private function.
Parameters: data (dict) – Information from the controller process Returns: None
-
_derive_charge
(config)[source]¶ Use a temperature window to identify the roast charge.
The charge will manifest as a sudden downward trend on the temperature. Once found, we save it and avoid overwriting. The charge is needed in order to derive the turning point.
Parameters: config (dict) – Current snapshot of the configuration Returns: None
-
_derive_turning_point
(config)[source]¶ Use a temperature window to identify the roast turning point.
Turning point relies on the charge being set first. We use the rolling 5-point window to measure slope. If we show a positive trend after the charge, then the temperature has begun to turn.
Parameters: config (dict) – Current snapshot of the configuration Returns: None
-
add_roast_event
(event)[source]¶ Add an event to the roast log.
This method should be used for registering events that may be worth tracking like first crack, second crack and the dropping of coffee. Similar to the standard reading output from the roaster, manually created events will include the current configuration reading, time and metadata passed in.
Parameters: event (dict) – Details describing what happened Returns: dict
-
connect
(interface=None)[source]¶ Connect to the USB for the hottop.
Attempt to discover the USB port used for the Hottop and then form a connection using the serial library.
Returns: bool Raises: SerialConnectionError –
-
drop
()[source]¶ Preset call to drop coffee from the roaster via thread signal.
This will set the following configuration on the roaster: - drum_motor = 0 - heater = 0 - solenoid = 1 - cooling_motor = 1 - main_fan = 10
In order to power-off the roaster after dropping coffee, it’s best to use the shutdown method. It’s assumed that cooling will occur for 5-10 minutes before shutting down.
Returns: None
-
end
()[source]¶ End the roaster control process via thread signal.
This simply sends an exit signal to the thread, and shuts it down. In order to stop monitoring, call the set_monitor method with false.
Returns: None
-
set_cooling_motor
(cooling_motor)[source]¶ Set the cooling motor config.
Parameters: cooling_motor (bool) – Value to set the cooling motor Returns: None Raises: InvalidInput
-
set_drum_motor
(drum_motor)[source]¶ Set the drum motor config.
Parameters: drum_motor (bool) – Value to set the drum motor Returns: None Raises: InvalidInput
-
set_fan
(fan)[source]¶ Set the fan config.
Parameters: fan (int [0-10]) – Value to set the fan Returns: None Raises: InvalidInput
-
set_heater
(heater)[source]¶ Set the heater config.
Parameters: heater (int [0-100]) – Value to set the heater Returns: None Raises: InvalidInput
-
set_interval
(interval)[source]¶ Set the polling interval for the process thread.
Parameters: interval (int or float) – How often to poll the Hottop Returns: None Raises: InvalidInput
-
set_main_fan
(main_fan)[source]¶ Set the main fan config.
Parameters: main_fan (int [0-10]) – Value to set the main fan Returns: None Raises: InvalidInput
-
set_monitor
(monitor)[source]¶ Set the monitor config.
This module assumes that users will connect to the roaster and get reading information _before_ they want to begin collecting roast details. This method is critical to enabling the collection of roast information and ensuring it gets saved in memory.
Parameters: monitor (bool) – Value to set the monitor Returns: None Raises: InvalidInput
-
set_roast_properties
(settings)[source]¶ Set the properties of the roast.
Parameters: settings (dict) – General settings for the roast setup Returns: None Raises: InvalidInput
-
set_simulate
(status)[source]¶ Set the simulation status.
Parameters: status (bool) – Value to set the simulation Returns: None Raises: InvalidInput
-
set_solenoid
(solenoid)[source]¶ Set the solenoid config.
Parameters: solenoid (bool) – Value to set the solenoid Returns: None Raises: InvalidInput
-
start
(func=None)[source]¶ Start the roaster control process.
This function will kick off the processing thread for the Hottop and register any user-defined callback function. By default, it will not begin collecting any reading information or saving it. In order to do that users, must issue the monitor/record bit via set_monitor.
Parameters: func (function) – Callback function for Hottop stream data Returns: None
-
Control Process¶
Due to the nature of continuously needing to poll the serial interface, a thread was required to handle interactions with the serial interface. It’s possible to use the multiprocessing module to handle this work, but when using this library inside of web server technology, multiprocessing often causes issues. Vanilla threads were used here to avoid interaction problems with co-routine or eventlet-based libraries.
-
class
pyhottop.pyhottop.
ControlProcess
(conn, config, q, logger, callback=None)[source]¶ Primary processor to communicate with the hottop directly.
Parameters: - conn (Serial instance) – Established serial connection to the Hottop
- config (dict) – Initial configurations settings
- q (Queue instance) – Shared queue to interact with the user interface
- logger (Logging instance) – Shared logger to keep continuity
- callback (function) – Optional callback function to stream results
Returns: ControlProces instance
-
_generate_config
()[source]¶ Generate a configuration that can be sent to the Hottop roaster.
Configuration settings need to be represented inside of a byte array that is then written to the serial interface. Much of the configuration is static, but control settings are also included and pulled from the shared dictionary.
Returns: Byte array of the prepared configuration.
-
_read_settings
(retry=True)[source]¶ Read the information from the Hottop.
Read the settings from the serial interface and convert them into a human-readable format that can be shared back to the end-user. Reading from the serial interface will occasionally produce strange results or blank reads, so a retry process has been built into the function as a recursive check.
Returns: dict
-
_send_config
()[source]¶ Send configuration data to the hottop.
Returns: bool Raises: Generic exceptions if an error is identified.
-
_valid_config
(settings)[source]¶ Scan through the returned settings to ensure they appear sane.
There are time when the returned buffer has the proper information, but the reading is inaccurate. When this happens, temperatures will swing or system values will be set to improper values.
Parameters: settings (dict) – Configuration derived from the buffer Returns: bool
-
_validate_checksum
(buffer)[source]¶ Validate the buffer response against the checksum.
When reading the serial interface, data will come back in a raw format with an included checksum process.
Returns: bool
-
_wake_up
()[source]¶ Wake the machine up to avoid race conditions.
When first interacting with the Hottop, the machine may not wake up right away which can put our reader into a death loop. This wake up routine ensures we prime the roaster with some data before starting our main loops to read/write data.
Returns: None
-
run
()[source]¶ Run the core loop of reading and writing configurations.
This is where all the roaster magic occurs. On the initial run, we prime the roaster with some data to wake it up. Once awoke, we check our shared queue to identify if the user has passed any updated configuration. Once checked, start to read and write to the Hottop roaster as long as the exit signal has not been set. All steps are repeated after waiting for a specific time interval.
There are also specialized routines built into this function that are controlled via events. These events are unique to the roasting process and pre-configure the system with a configuration, so the user doesn’t need to do it themselves.
Returns: None

Deprecation¶
Table of contents
Introduction¶
Xapian’s API is fairly stable and has been polished piece by piece over time, but it still occasionally needs to be changed. This may be because a new feature has been implemented and the interface needs to allow access to it, but it may also be required in order to polish a rough edge which has been missed in earlier versions of Xapian, or simply to reflect an internal change which requires a modification to the external interface.
We aim to make such changes in a way that allows developers to work against a stable API, while avoiding the need for the Xapian developers to maintain too many old historical interface artefacts. This document describes the process we use to deprecate old pieces of the API, lists parts of the API which are currently marked as deprecated, and also describes parts of the API which have been deprecated for some time, and are now removed from the Xapian library.
It is possible for functions, methods, constants, types or even whole classes to be deprecated, but to save words this document will often use the term “features” to refer collectively to any of these types of interface items.
Deprecation Procedure¶
Deprecation markers¶
At any particular point, some parts of the C++ API will be marked as
“deprecated”. Deprecated features are annotated in the API headers with macros
such as XAPIAN_DEPRECATED()
, which will cause compilers with appropriate
support (such as GCC 3.1 or later, and MSVC 7.0 or later) to emit compile-time
warnings if these features are used.
If a feature is marked with one of these markers, you should avoid using it in new code, and should migrate your code to use a replacement when possible. The documentation comments for the feature, or the list at the end of this file, will describe possible alternatives to the deprecated feature.
If you want to disable deprecation warnings temporarily, you can do so
by passing "-DXAPIAN_DEPRECATED(X)=X"
to the compiler (the quotes are
needed to protect the brackets from the shell). If your build system uses
make, you might do this like so:
make 'CPPFLAGS="-DXAPIAN_DEPRECATED(X)=X"'
API and ABI compatibility¶
Releases are given three-part version numbers (e.g. 1.2.9), the three parts being termed “major” (1), “minor” (2), and “revision” (9). Releases with the same major and minor version are termed a “release series”.
For Xapian releases 1.0.0 and higher, an even minor version indicates a stable release series, while an odd minor version indicates a development release series.
Within a stable release series, we strive to maintain API and ABI forwards compatibility. This means that an application written and compiled against version X.Y.a of Xapian should work, without any source changes or need to recompile, with a later version X.Y.b, for all b >= a. Stable releases which increase the minor or major version number will usually change the ABI incompatibly (so that code will need to be recompiled against the newer release series. They may also make incompatible API changes, though we will attempt to do this in a way which makes it reasonably easy to migrate applications, and document how to do so in this document.
It is possible that a feature may be marked as deprecated within a minor release series - that is from version X.Y.c onwards, where c is not zero. The API and ABI will not be changed by this deprecation, since the feature will still be available in the API (though the change may cause the compiler to emit new warnings when rebuilding code which uses the now-deprecated feature).
Users should generally be able to expect working code which uses Xapian not to stop working without reason. We attempt to codify this in the following policy, but we reserve the right not to slavishly follow this. The spirit of the rule should kept in mind - for example if we discovered a feature which didn’t actually work, making an incompatible API change at the next ABI bump would be reasonable.
Normally a feature will be supported after being deprecated for an entire stable release series. For example, if a feature is deprecated in release 1.2.0, it will be supported for the entire 1.2.x release series, and removed in development release 1.3.0. If a feature is deprecated in release 1.2.1, it will be supported for the 1.2.x and 1.4.x stable release series (and of course the 1.3.x release series in between), and won’t be removed until 1.5.0.
Experimental features¶
During a development release series (such as the 1.1.x series), some features may be marked as “experimental”. Such features are liable to change without going through the normal deprecation procedure. This includes changing on-disk formats for data stored by the feature, and breaking API and ABI compatibility between releases for the feature. Such features are included in releases to get wider use and corresponding feedback about them.
Deprecation in the bindings¶
When the Xapian API changes, the interface provided by the Xapian bindings will usually change in step. In addition, it is sometimes necessary to change the way in which Xapian is wrapped by bindings - for example, to provide a better convenience wrapper for iterators in Python. Again, we aim to ensure that an application written (and compiled, if the language being bound is a compiled language) for version X.Y.a of Xapian should work without any changes or need to recompile, with a later version X.Y.b, for all a <= b.
However, the bindings are a little less mature than the core C++ API, so we don’t intend to give the same guarantee that a feature present and not deprecated in version X.Y.a will work in all versions X+1.Y.b. In other words, we may remove features which have been deprecated without waiting for an entire release series to pass.
Any planned deprecations will be documented in the list of deprecations and removed features at the end of this file.
Support for Other Software¶
Support for other software doesn’t follow the same deprecation rules as for API features.
Our guiding principle for supporting version of other software is that we don’t aim to actively support versions which are no longer supported “upstream”.
So Xapian 1.1.0 doesn’t support PHP4 because the PHP team no longer did when it was released. By the API deprecation rules we should have announced this when Xapian 1.0.0 was released, but we don’t have control over when and to what timescales other software providers discontinue support for older versions.
Sometimes we can support such versions without extra effort (e.g. Tcl’s stubs mechanism means Tcl 8.1 probably still works, even though the last 8.1.x release was over a decade ago), and in some cases Linux distros continue to support software after upstream stops.
But in most cases keeping support around is a maintenance overhead and we’d rather spend our time on more useful things.
Note that there’s no guarantee that we will support and continue to support versions just because upstream still does. For example, we ceased providing backported packages for Ubuntu dapper with Xapian 1.1.0 - in this case, it’s because we felt that if you’re conservative enough to run dapper, you’d probably prefer to stick with 1.0.x until you upgrade to hardy (the next Ubuntu LTS release). But we may decide not to support versions for other reasons too.
How to avoid using deprecated features¶
We recommend taking the following steps to avoid depending on deprecated features when writing your applications:
- If at all possible, test compile your project using a compiler which supports warnings about deprecated features (such as GCC 3.1 or later), and check for such warnings. Use the -Werror flag to GCC to ensure that you don’t miss any of them.
- Check the NEWS file for each new release for details of any new features which are deprecated in the release.
- Check the documentation comments, or the automatically extracted API documentation, for each feature you use in your application. This documentation will indicate features which are deprecated, or planned for deprecation.
- For applications which are not written in C++, there is currently no equivalent of the
XAPIAN_DEPRECATED
macro for the bindings, and thus there is no way for the bindings to give a warning if a deprecated feature is used. This would be a nice addition for those languages in which there is a reasonable way to give such warnings. Until such a feature is implemented, all application writers using the bindings can do is to check the list of deprecated features in each new release, or lookup the features they are using in the list at the end of this file.
