--- layout: post title: When Should You Spend Time on Technical Vision ---
One of the challeging things about being a technical leader is knowing how much time to spend on big-picture vision setting vs. writing code and solving the problems of today. Spend too much time on vision setting and you may start designing solutions which are disconnected from reality. However, if you don't spend enough time on vision your team will sputter over the long-term. Over the last couple of years I've found a few heuristics to apply which let you know when it's time to jump into "vision setting mode".
Before digging into when you need to spend more time setting a technical vision, it's important to understand what a technical vision looks like. A technical vision can take many forms, but it's most often an aspirational document (frequently ~2 -> 5 pages) which outlines an ideal future technical state that a team will achieve over the next 18+ months. Technical visions are useful as an anchor point in the cone of strategy to help tie-break day-to-day technical decisions. They rarely end up being exactly correct, but they can also serve as a useful tool to elucidate any large gaps in what your team is currently building and help the team take a first step towards fixing those gaps.
All of those things seem great, so why not just spend all of your time on technical vision? Unfortunately, creating one comes with a cost. The first cost is obvious: drafting and building consensus around a vision takes substantial amount of time from the author and reviewers to make sure the vision is directionally correct. Vision documents also come with a cost for the team. Once drafted, you actually need to get the team to shift course and use that vision in their day to day decision making. While this is useful, it also takes time, and can lead to a feeling of whiplash if the team feels like they're changing their north star too frequently. So, what are some cues you can use to know that it's time to pay this cost and draft a technical vision?
One of the first signs that the team needs a clearer technical vision is if the team is constantly getting bogged down in small design decisions. While some design push-and-pull is to be expected on code reviews and design documents, the team should spend most of their day-to-day time discussing questions on the margins rather than constantly re-litigating core questions about what you're building.
If you start to see the team having these "re-litigate the world" discussion frequently, chances are there's a few key underlying architectural decisions which the team has not investigated and decided upon. Drafting a technical vision can help bring these disagreements to the forefront and allow the team to come to a consensus about how to architect a solution to these problems. While the vision won't magically solve all design disagreements, having an agreed-upon north star should prevent the team from churning on the same design issues every code review.
Sometimes teams will encounter a situation where they can make design decisions effectively, but it feels like many decisions are time-consuming because they require "inventing the architecture as they go". In these situations, the problem isn't so much disagreement so much as confusion about how all of the pieces of the system should fit together. This means that simple questions like "how should we deploy this thing" becoming sprawling discussions without about "well how do we even want to use Jenkins here". While some amount of this type of "zoom out" thinking is useful, if you find it's slowing down the team it may be time to invest in clarifying your technical vision.
Resolving vision gaps in these cases is often slightly different than in Case #1, as there may not be any core disagreements to resolve. Instead, it may just be a case of a team having differing expertise, and no one has yet stitched all of the moving pieces into a coherent narrative. As a result, in these cases may have less disagreement-resolution, and more stitching-together disparate pieces of context into a coherent whole.
Sometimes it becomes clear that your current way of doing things just won't work.  Regardless of the symptoms, if your team is churning through problems as best it can, but it seems like you're stil falling behind, chances are you need to do a clarify your technical vision and chart a path to something fundamentally better.
These types of technical vision can feel a little different than ones created for the other two cases. They will still chart a course to a glorious future, but they also need to come with a concrete first step ("we will start on this vision by doing X to solve our immediate scalability needs") which helps the team out of its current situation.
These three cases aren't the only times teams will need to clarify their technical vision, they do represent three common cases to look out for. So, if you find yourself repeatedly bogged down in the same technical discussions, struggling to fit together a number of disparate design decisions into a coherent story, or just stuck in a technical rut, it's worth asking yourself "does our team have a clear enough vision about how to solve this problem" and filling that gap if not.

Pustike JSON library provides an ObjectMapper
class that can create Java objects from JSON or create JSON value from Java objects, by using Jakarta JSON-P APIs internally.
The key feature of this object mapper is its ability to generate JSON values with only specified list of fields/properties of an object depending on the given context. For ex, when a list of customer objects are being shown in a select field, very few properties like code and name are required. But when editing the same customer object, many additional properties are needed which can be defined in another context. This helps in reducing the transferred data size when communicating with JSON objects in the API.
Following are some of its features:
JsonValue
, optionally in the given context to include listed fields only.@JsonIncludes
allows multiple contexts to be defined on a class with each of them listing fields to be included in JSON format.TypeConverter
utility class to convert objects between given source and target types.Dependencies

2 Ghanaian soldiers, prison officer arrested for robbing mining firms in Ashanti Region
Three security officers are being investigated by the police for allegedly robbing small scale mining firms in the Ashanti Region.
They were arrested on Wednesday, November 6, 2019 at Koniyaw, a community near the Bekwai Municipality —about an hour drive from the regional capital, Kumasi.
They have been named as Staff Sargent Francis Kwame Boateng and L/Cpl Richard Anyimadu, both military personnel and L/Cpl Joseph Trezeguet, a prison officer at the Kumasi Central Prisons.
The uniform men were arrested with six other civilians whilst trying to escape with their loot, police sources told DailyMailgh.com.
Kwame Poku, a small scale miner at Koniyaw told our correspondent J. Ofori that the suspects stormed their mining site and demanded gold and money.
“They took some gold, it was in a blanket, and then they continued to ask us for money,” Poku stated.
After further searches, the suspected robbers left in an unregistered Ford transit driven by Agyemang Prempeh, a native of Bekwai.
The victims of the robbery then alerted the police. A police patrol team was informed about the robbery incident and immediately moved to the scene and bumped into the suspects numbering about 12.
Seven of the suspects managed to flee the scene whilst four of them including Sargent Francis Kwame Boateng and L/Cpl Joseph Trezeguet.
While heading to the police station with the suspects, Sargent Francis Kwame Boateng managed to fall from the moving vehicle and escaped into the bush.
He was later arrested together with six other suspects by some town folks at about 11pm after a search.
Police retrieved 3BB Cartridges and a blanket containing the gold concentrates suspected to have been seized by the suspects.
Two water pumping machines and the Ford vehicle have also been kept as exhibits by the police.
Police sources at the Bekwai Divisional Police Command say the suspects had been transported to the Ashanti Regional Police Headquarters for further interrogation.
The command is yet to comment on the matter as it intensifies efforts to arrest other suspects.

This tool is used to generate a flow accumulation raster using the simple D8 (O'Callaghan and Mark, 1984) algorithm. It is a parallel alternative to the D8 and Rho8 Flow Accumulation tool and is currently considered to be experimental. It may result in performance improvements compared with the serial tool, depending on the users system. Changes may occur to this tool in the future.
The user must specify the name of a digital elevation model (DEM) that has been hydrologically corrected to remove all spurious depressions and flat areas. DEM pre-processing is usually achived using the Fill Depressions tool or the Breach Depressions (Fast) tool.
The following is an example of a Python script that uses this tool:
wd = pluginHost.getWorkingDirectory()
demFile = wd + "DEM.dep"
outputFile = wd + "pointer.dep"
runParallel = "true"
args = [demFile, outputFile, runParallel]
pluginHost.runPlugin("D8FlowAccum", args, False)
This is a Groovy script also using this tool:
def wd = pluginHost.getWorkingDirectory()
def demFile = wd + "DEM.dep"
def outputFile = wd + "pointer.dep"
def runParallel = "true"
String[] args = [demFile, outputFile, runParallel]
pluginHost.runPlugin("D8FlowAccum", args, false)

class Hike::CachedTrail
`CachedTrail` is an internal cached variant of `Trail`. It assumes the file system does not change between `find` calls. All `stat` and `entries` calls are cached for the lifetime of the `CachedTrail` object.
Attributes
`CachedTrail#aliases` is an immutable `Hash` mapping an extension to an `Array` of aliases.
`CachedTrail#extensions` is an immutable `Extensions` collection.
`CachedTrail#paths` is an immutable `Paths` collection.
`CachedTrail#root` returns root path as a `String`. This attribute is immutable.
Public Class Methods
`CachedTrail.new` is an internal method. Instead of constructing it directly, create a `Trail` and call `Trail#CachedTrail`.
# File lib/hike/cached_trail.rb, line 20 def initialize(root, paths, extensions, aliases) @root = root.to_s # Freeze is used here so an error is throw if a mutator method # is called on the array. Mutating `@paths`, `@extensions`, or # `@aliases` would have unpredictable results. @paths = paths.dup.freeze @extensions = extensions.dup.freeze # Create a reverse mapping from extension to possible aliases. @aliases = aliases.dup.freeze @reverse_aliases = @aliases.inject({}) { |h, (k, a)| (h[a] ||= []) << k; h } @stats = Hash.new { |h, k| h[k] = FileUtils.stat(k) } @entries = Hash.new { |h, k| h[k] = FileUtils.entries(k) } @patterns = Hash.new { |h, k| h[k] = pattern_for(k) } end
Public Instance Methods
`CachedTrail#cached` returns `self` to be compatable with the `Trail` interface.
# File lib/hike/cached_trail.rb, line 44 def cached self end
A cached version of `Dir.entries` that filters out `.` files and `~` swap files. Returns an empty `Array` if the directory does not exist.

See `Trail#find` for usage.
# File lib/hike/cached_trail.rb, line 55 def find(*logical_paths) find_all(*logical_paths).first end
The real implementation of `find_all`. `Trail#find_all` generates a one time index and delegates here.

This post assumes you know what a retrospective is and focuses on an activity to set the stage challenging what Kert’s prime directive means to the group.
This is an 80% muted–no talking–activity to use at the start of your retro. It should last between 5 to 10 minutes.
Often the facilitator asks the group for a verbal yes to agree with Kerth’s prime directive. Most people can see its value but sometime you get a “yeaahh sure I agree… they did the best job they could” but what that person really thinks is “they did a really stinky job”.
Sometime people think that about themselves.
When to use the activity
I’d use this activity on groups new to Kerth’s prime directive or groups where an individual dismissed the directive.
The objective is to give time to the group to better understand the meaning of the sentence.
Before using this activity make sure you fully understand the directive yourself or it will be challenging to deal with questions from your group.
Activity introduction
The facilitator reads the prime directive and explains that by accepting it the group will make retrospective a more constructive and effective environment.
Regardless of what we discover, we must understand and truly believe that everyone did the best job he or she could given what was known at the time, his or her skills and abilities, the resources available, and the situation at hand.
Norm Kerth prime directive
Instead of asking the group for the directive acceptance with a verbal yes tell them we will spend a few minutes questioning the directive.
Give the group a minute or two to remember an episode in their previous job where they believe the prime directive could not be applied. Read the directive highlighting the givens portion:
- given what was known at the time
- given his or her skills and abilities
- given the resources available
- given the situation at hand
After the two minutes of thinking back–or less–ask them to summarize the episode on a post-it note. If people believe in the directive you can ask to summarize an episode where the directive was applicable.
Once done writing ask them to reflect on the factors that might have affected that episode:
- what was known at the time of the episode/incident
- what were that person’s–or group–skills and abilities
- what resources–time, team size, bandwidth–were available
- what was the situation at hand
Reflecting about these factors will help us gain a better understanding of the events we look during retrospective.
Activity debriefing
After reflecting on how these factors impacted the job done ask if they still think the best job wasn’t done given these factors or if perhaps they don’t know how to answer about these factors.
Now is the time to ask each participants if they accept the prime directive for today’s retrospective.
Skeptics in the group
Remind the group that it’s ok to still think the directive doesn’t apply to their episode.
Ask if they are ok sharing the episode with the group and try to understand the factors. Also acknowledge that sometimes there are extreme situations where individuals might purposely sabotaging projects and use an unprofessional conduct.
Ask them if they are ok putting aside their biases and accept the directive for the duration of today’s retrospective.
If they accept thank them. If they still refuse–even just for today’s retro–there must be a deeper issue that needs to be tackled.
If it’s an individual I’d say continue the retrospective and keep an eye on his/her behavior and follow-up one-on-one afterwards.
If the majority of the group feels that way it’s better to call the retrospective off and investigate further on the root cause of that tension.
Conclusion
Retrospectives are the most important part of an iteration and changing their format is imperative to keep people engaged.
If people understand Kerth’s prime directive printing it out and reminding people about it is usually enough.
When people are new to Kerth’s prime directive it’s good to explain it and challenge it instead of getting a–often disengaged–verbal yes.
Before trying this activity make sure you fully understand the directive there is another great post about questioning the directive with input from though leaders in the retrospective community.

The easiest way to try out MapStore2 is to download and extract the binary package available on MapStore2 release page. Here you can find some preconfigured maps as well users and groups. The goal for this package is to ease all the requirements needed for you to take MapStore2 for a test-drive.
We hope you enjoy MapStore2!
Go to the location where you saved the zip file, unzip the contents and run:
Windows: mapstore2_startup.bat
Linux: ./mapstore2_startup.sh
Point your browser to: http://localhost:8800/mapstore
To stop MapStore2 simply do:
Windows: mapstore2_shutdown.bat
Linux: ./mapstore2_shutdown.sh

We have provided a way to input your current location, and based on the weather at your location, we will supply you with an awesome playlist from Spotify. From sunshine to snowfall, we have you covered! If you were wishing you were in another city, don't fret! Feel free to input a desired location and get a playlist to compliment the weather there.


--- layout: post title: ServiceAPI - Attaching keywords categories: [] tags: dotnet-serviceapi-client serviceapi status: publish type: post published: true meta: {} ---
Keywords (otherwise known as Thesaurus terms) use the child collection pattern to establish a relationship with a record, this is similar to other related objects such as holds and locations. One difference with keywords is that you cannot use the standard pattern of adding them to the child collection.
Unfortunately existing releases (up to and including 8.2) do not throw an exception to tell you that the adding of the keyword to the ChildKeywords collection has not worked, they simply fail. You should expect that an upcoming release will actually throw an exception and give you a clue how you proceed.
In 8.2 a keyword is added using the AttachKeyword service action, using the .Net client classes you would do something like this:
TrimClient trimClient = new TrimClient("http://david-pc/ServiceAPI82"); trimClient.Credentials = System.Net.CredentialCache.DefaultCredentials; Record request = new Record(); request.Uri =<PHONE_NUMBER>; AttachKeyword attachKeyword = new HP.HPTRIM.ServiceModel.AttachKeyword() { KeywordToAttach = new KeywordRef() { Uri =<PHONE_NUMBER> } }; request.AddAction(attachKeyword); try { var response = trimClient.Post<RecordsResponse>(request); } catch (WebServiceException wex) { Console.WriteLine(wex.ErrorMessage ?? wex.Message); }
The code above posts a JSON object similar to this:
{ "Uri":<PHONE_NUMBER>, "ActionsToCall": [ { "__type": "HP.HPTRIM.ServiceModel.AttachKeyword", "AttachKeywordKeywordToAttach":<PHONE_NUMBER> } ] }
Given that the AttachKeyword action was added in 8.2 options are limited for earlier versions, in 8.1 you may choose to write your own plugin, other than that you might have to avoid keywords.

There
seems to be some division of opinion about Microsoft .NET - not
least of all from the Marketing department. I was told at a MS breakfast
briefing (7 am) late last year not to expect .NET to make an impact
"for the next three to five years." On the face of it,
it appears that Microsoft just got every MS Certified Partner in
the country out of bed two hours early just to say "You can
all go back home to bed for another three to five years. Have a
croissant on the way out. Thanks for coming."
During
that presentation Microsoft executives outlined their vision for
the new .NET. It combines renting software over the Internet, integrating
Web documents seamlessly with each other using public, standardized
XML schemas, and enabling users to easily manipulate Web content
that has been primarily static.
So,
the main question that developers have, is VB.NET and ASP.Net ready
now or should I keep plugging away at VB6 and ASP?
The
first thing to be aware of is that Visual Studio.Net is not stable
- it is pretty flakey. However the .NET Framework is stable -
this means that once you get the code written it runs fine for the
user.
The
second thing to know is that code written in Beta 1 will break in
Beta 2 (especially ADO.Net database code). However this is not that
important now as Beta 2 is just about cooked. Microsoft is expected
to release 2 million copies of the second beta version of Visual
Basic.Net at its Tech Ed conference in Atlanta starting today!!!
According
to MS, Code written in Beta 2 will compile in the final release.
That is unless Microsoft need to change an API to fix a bug OR of
course they change their mind. So be prepared to rewrite some sections
of your code.
So
you need to consider deployment - ASP.NET users need only IE installed
so no hastles there if you can get the .NET Framework installed
on the server. For a lot of developers this means it is a goer.
Thinking
about VB.NET you will need client workstations to have the the .NET
Framework installed to use your VB.NET executables. There will be
no .NET built into Windows until the version after Win XP (Blackcombe).
Are you prepared to have beta code on your client machines? Are
you prepared to format the client machines because there is no migration
path? For me this means VB.NET is a no goer.
So
you need to talk with your client on the PROs and CONs. They essentially
boil down to:
-
Code
is easier to maintain - especially comparing ASP to ASP.NET
-
It
is slower to work in a beta when there are bugs and features missing.
You get to know what they are. The main problem is the lack of
documentation and a Microsoft Knowledgebase with the Bug and the
suggested workaround.
-
Pay Now or Pay Later? If you develop now in ASP.NET or VB.NET
instead of ASP or VB it lessens the overall cost - as you are
probably going to move the app to .NET in the future anyway.
So
talk seriously with your client and decide. Basically it's
OK to develop in .NET if all parties involved know and accept the
risks.
For
what it is worth I am not waiting for the 3 to 5 years.....
Cheers
until next time,

Computers today are an inseparable part of various fields and our day to day life. They have revolutionised many industries through the use of data, automation, communication and other various different methods; but one of the most important application of computers to me has been in the field of education. Technological advancement in computing has made computers more and more accessible, with almost 56% of the global population, a continuously growing number having access to the internet. Computers have made a meaningful impact in distant learning, sharing resources and they have proven themselves to be a brilliant teaching and learning aid in all stages of education.
Applications of using computers in eduction.
Advancements in data processing and storage technologies, communication technologies and development of web technologies have various applications in the teaching and learning process. The advantages of computers in education primarily include:
- Creating and storing resources digitally
- Quick data processing, which has applications in interactive tutorials, data visualisation, personalised learning etc.
- Audio-visual aid in teaching
- Better presentation of information using animation, presentation software etc.
- Access to the internet which has many applications in distant and self learning
- Quick communication with students, teachers and parents
In a modern education system, students have access to information far beyond the scope of their syllabus which is made for learners on many different levels. The internet has fantastic resources, many of which are available for free, that overcome problems such as the stigma of asking for help when a student has a difficulty in understanding a certain material because it is too advance which makes the content inaccessible for them.
Why should we use computers in education?
Digital resources are also easier to create; more efficient to use, store and distribute and more sustainable compared to paper. All of this paired with better communication technologies is making getting help more accessible to students than ever before.
Computers aid in teaching and learning. Their popularity in recent years has reduced the cost of manufacturing so that more people can afford them. Hardware such as touchscreen makes them more intuitive, e-ink tablets reduce the strain on user’s eyes while allowing access to digital resources. Digital note taking is one my favourite application of computers in education, digital notes are easy to create, organise, share and safeguard.
Computers are the most valuable tool in distant learning. Physically distant locations have come closer due to Internet accessibility. There are many online educational courses available which can be tailored to a student based on their own pace and needs.
In summary, the use of computers has made education more accessible and convenient for everyone. Emerging technologies such as VR and AR will continue to improve upon existing applications in education and also further undiscovered applications.

This Privacy Policy is part of the Terms & Conditions of using this website, so please read it carefully. We take your privacy extremely seriously, and commit to storing all your personal information securely.
Whenever you visit the website, we gather information about what you do during your visit, including the searches that you perform and the records you view. We also gather some statistics about your computer, such as the browser you use and how big your screen is. We gather personal information (e.g. name, address, phone number, email address, postal address) about you when you register, pay for a service or get in contact with us, or sometimes if you reply to a survey. By using this website you agree to be bound to the terms of this Privacy Policy.
If you create a family tree or create content on the website, we also manage that information, which may include personal information about you and other people (for example, names and birthdays of people in your family). We always aim to gather only the information that we need in order to provide the records and services which you have subscribed to and/or purchased PayAsYouGo credits for.
We won’t keep your personal information for longer than is necessary and will only use the personal information that we gather to:
We keep your details safe when you sign in or pay by using encryption. We always use up-to-date technology security standards and make every effort to keep our systems as secure as they can reasonably be. Please be aware that although our systems are secure, your information might be intercepted on its way to us via the internet, although it is extremely uncommon for this to happen. Keep your sign in details private at all times, do not share them with anybody.
When we take a payment from you, we use a secure third party service to process the payment and do not keep a record of your credit or debit card details in our systems. This means that even if (in the very unlikely event) someone broke into our systems, your payment details would not be available for them to steal.
We won’t ever sell your information to third parties, full stop. If we run a promotion or competition where your information would be shared with a third party for marketing purposes, we will always ask your permission first.
Only specific people within our Group Companies (meaning brightsolid online publishing (US) Limited), and any subsidiary and/or parent company of brightsolid online publishing (US) Limited that might exist in the future have access to your information. We restrict this as much as we can. We aim to make sure that people only have as much access to your information as they need to carry out their job in providing you with services and records.
We occasionally use third party companies to manage information that you provide us with. When we do, we keep the amount of personal information they hold to an absolute minimum, have contracts in place to stop them using your information except on our behalf and obviously use reasonable efforts to make sure they are as careful with your information as we are.
The vast majority of your information is stored securely on our servers in Scotland. Some of our third party partners use servers in the United States. When we process data in the United States, we only use providers certified under the EU-approved Safe Harbor scheme and we abide by the “safe harbor” framework set forth by the US Department of Commerce.
If your account is inactive for two or more years and you are not paying for a service, we reserve the right to delete your information (including information in your family tree), although we’ll try to contact you first. Of course, if you have an active subscription or PayAsYouGo credits, we won’t do this.
Information stored in your family tree will, in almost all cases, include personal information about other people that are still alive. As with all information in your family tree, your information may be searchable by fajar.com users (together with users of other websites) and may appear on internet searches, but all of the information will not be viewable unless you explicitly give them permission to view your tree.
You should always seek permission from people who are living before you make their personal information available in your tree, or anywhere else online. We have provided you with privacy controls to manage your family tree and control who can see the information in it. You should familiarize yourself with how they work as you’re responsible for using them to protect the information you have provided. We reserve the right (at our own discretion) to remove any personal data which you have included in your family tree about people who are living if we are alerted to the fact that this personal data was used without that person’s permission. If you become aware that your personal information has been included in somebody else's tree without your permission or is being misused in any other way on the fajar.com site, please send an email to our Customer Support team with details and we will investigate and, if necessary, remove this information.
We try only to send you emails which are relevant and help you with your family history or tell you important things about the website. There are some emails which we send you only if we have your permission (marketing emails) and you can notify us at any time if you no longer wish to receive these marketing emails (see below). There are some emails which we send you even if we don’t have your permission (service emails) - we send these to administer the service. Both types are explained below.
These emails include our regular newsletter, emails which help you with your family history, special offers and market research emails. They also include product updates: announcements of new features or historical records on the website. Very occasionally, we might tell you about a service offered by another company within our group, or even outside it, but this is rare.
There are several ways to do this and we aim to make it as easy as possible for you. The easiest way is to change the settings in the “my account” area of the website. There are also instructions on every email we send and you can usually unsubscribe directly from the email without visiting the website.
We send these out to administer the service. Service emails include registration and payment confirmations, warnings that we are about to charge you or that your subscription or credits are about to expire, and welcome emails that provide useful information about how to use a service or feature when you sign up or start using it. Also, if we make a fundamental change to the website or our Terms & Conditions that we think we need to make you aware of (for legal or simply for courtesy reasons), we will send you a service email.
Because of the nature of these emails, we don’t allow you to unsubscribe, but we can switch off your account if you are no longer interested in using the website. Contact our Customer Support team to do this.
We use cookies (small information files that are stored on your computer) to help us provide many features on the website. You can choose not to accept cookies from us (by changing your browser’s security settings) but if you do, the website might not work as intended and some features may not work at all.
If you want to know what personal information we hold on you, get in contact and we’ll be happy to supply you with it: there is a $6.35 administration charge to cover the cost of compiling this.
If the information we hold about you is no longer correct, please update your details in the “my account” area or alternatively, let us know and we will update our records.
We will only disclose your information to somebody outside our group companies (or who is processing your information on our behalf under contract) if we are required to by law.
If the fajar.com business transfers to anyone else, you agree that we can pass your information to that person, so they can continue to provide you with the service.
Any changes to this policy must be in writing and posted under this Privacy Policy in order to have any effect.


Thanks to our followers, the Boquete Jazz & Blues Festival is a very successful event. Over the years, the festival has grown and attendance has increased. Valle Escondido has been the festival's home for the past few years, however, a larger venue was needed to accomodate more festival goers and provide even more music. Boquete's "Festival de las Flores" fairgrounds will be our new home for 2018. Here we will be able to take the festival to the next level by including art exhibits, vendor stands and of course a variety of food and beverage. The fairgrounds offer us greater seating capacity and room to delight our public, including two stages with continuous music.


S2Container.NET version 1.1 and higher includes testing framework to make testing much easier.
The framework extends MbUnit and has the following features:
If there is a field in a Test class that is not neither static, readonly, nor final and there exists a component with a name that equals the field name without the underscore (prefix or suffix), then that field and the component will be binded.
If there is a component (reference datatype or DateTime) in a container that can be substituted, that component is retrieved from the S2Container and set.
When the test method finishes, values that were set are reset to null (Nothing in VB).
If SetUpXxx() method and TearDownXxx() method is defined, they will be called after SetUp() method and before TearDown() method. Initialization and clean up steps for each test may be written in these methods.
If TxEnumerator(Seasar.Extension.Unit.Tx) is set to Rollback(Enumerator) in the S2 attribute in test method, transaction will marked to begin just before the test method and rolled back after test method finishes execution. This will allow tests to be repeated with the same set of database data.
New DataSet may be retrieved by a primary key using Reload(DataSet) to reload data. Result from an execution may be compared with the expected result entered in Excel.
Example:
DataSet expected = ReadXls("expectedResult.xls");
S2Assert.AreEqual(expected, Reload(expected);
Expected result of datatype DataSet may be compared to IList of IDictionary and IDictionary, object, IList of object by using the S2Assert.AreEqual() function.
Test class is created by extending Seasar.Extension.Unit.S2TestCase. This class should define TestFixture attribute(MbUnit.Framework.TestFixtureAttribute).
Test method should define Test attribute(MbUnit.Framework.TestAttribute) as well as S2 attribute(Seasar.Extension.Unit.S2Attribute). The test class will then create a S2Container.
<TestFixture()> _
PublicClass HogeTest
Inherits S2TestCase
<Test(), S2()> _
Publicsub TestHogeHoge()
' test codesEndSubEnd Class
S2TestClass has Register(), GetComponent(), and Include() methods that may be used with S2Container.NET.
C#
publicvoid TestHogeHoge()
{
// read dicon file
Include("Hoge.dicon");
// Register components into a S2Container
Register(typeof(Hashtable));
// Retrieve components from a S2Container
Hashtable table = (Hashtable) GetComponent(typeof(Hashtable));
}
VB.NET
<Test(), S2()> _
Publicsub TestHogeHoge()
' read dicon file
Include("Hoge.dicon")
' Register components into a S2Container
Register(typeof(Hashtable))
' Retrieve components from a S2ContainerDim table As Hashtable = CType(GetComponent(GetType(Hashtable)), Hashtable)
' when there is no explicit cast, may be defined as below' Dim table As Hashtable = GetComponent(GetType(Hashtable))End Sub
If the PATH of the dicon file is the same as the namespace of the test class, path in the namespace may be omittted. When PATH of the dicon file is specified in the file system, path will become relative path from the assembly. (However, process such as the buildin event, to output to the same folder as the assembly is necessary.)
if Test.dicon is in the namespace Foo.Fuga, it is possible to omit dicon file path on classes that are in Foo.Fuga namespace.
If there is a field in a Test class that is not neither static, readonly, nor final and there exists a component with a name that equals the field name without the underscore (prefix or suffix), then that field and the component will be binded.
If there is a component (reference datatype or DateTime) in a container that can be substituted, that component is retrieved from the S2Container and set.
If SetUpXxx() method and TearDownXxx() method is defined, they will be called after SetUp() method and before TearDown() method. Initialization and clean up steps for each test may be written in these methods.
C#
[TestFixture]
publicclass HogeTest : S2TestCase
{
publicvoid SetUpHogeHoge()
{
// initialization process
}
[Test, S2]
publicvoid TestHogeHoge()
{
// test codes
}
publicvoid TearDownHogeHoge()
{
// final processing
}
}
VB.NET
<TestFixture()> _
PublicClass HogeTest
Inherits S2TestCase
PublicSub SetUpHogeHoge()
' initialization processEndSub
<Test(), S2()> _
PublicSub TestHogeHoge()
' test codesEndSubPublicSub TearDownHogeHoge()
' final processingEndSubEnd Class
If TxEnumerator(Seasar.Extension.Unit.Tx) is set to Rollback(Enumerator) in the S2 attribute in test method, transaction will marked to begin just before the test method and rolled back after test method finishes execution. This will allow tests to be repeated with the same set of database data.
If Commit(Enumerator) in TxEnumerator is specified beside Rollback, transaction will be committed. If NotSupported(Enumerator) is specified, transaction will not begin. If TxEnumerator is not assigned to a S2 attribute, it will default to NotSupported(Enumerator).
Furthermore, to use transaction, a dicon file with TransactionContext and DataSource definition is necessary.
In this example, employee table is queried using employee number as a key. When employee table is queried for employee number 9900, that row joined with corresponding row from the deptartment table is returned.
The test case for this example should consist of expected employee table row and department table row. This expected data is specified in an Excel sheet - sheet name should correspond to the database table name, first row in the sheet should contain column names, and expected row data should be specified from the second row. The data may be manually entered into the Excel sheets or generated from the database table.
To run this example, first Setup a database to create a demostration database table used in this example. Excel sheets may then be filled with data from the database table using tool Db2ExcelClient in Seasar.Examples.
SqlReader fills DataSet from the database tables. The first argument to AddTable is the tableName(sheetName). The second argment should contain the condition.
XlsWriter outputs DataSet to Excel. File path relative to the output folder is specified in the constructor.
Data from a database table may be written out to an Excel sheet by executing Read() method in SQLReader class retrieved from IS2Container and then executing Write() method in XlsWrite class retrieved from IS2Container.
Check to make sure the data was created by executing Seasar.Examples, selecting S2Container reference from the tree, selecting "Test on Select Query(1)". There should be GetEmployeePrepare.xls in the folder Visual Studio output path + specified path (example: bin\Debug\Seasar.Examples\Reference\S2Unit). Double click on GetEmployeePrepare.xls to open this Excel sheet. In emp sheet, change EMPNO to 9900, ENAME to SCOTT2, DEPTNO to 99. In the dept sheet, change DEPTNO to 99, DNAME to RESEARCH2. Save and close the sheets.
Next, it is necessary to create data to verify data. Db2ExcelClient2 (available in Seasar.Examples) may be used to create this data.
using System.Data;
using MbUnit.Core.Cons;
using MbUnit.Framework;
using Seasar.Extension.DataSets.Impl;
using Seasar.Extension.Unit;
namespace Seasar.Examples.Reference.S2Unit
{
[TestFixture]
publicclass EmployeeDaoTest : S2TestCase
{
private IEmployeeDao dao_ = null;
publicvoid SetUpGetEmployee()
{
Include("Seasar.Examples/Reference/S2Unit/EmployeeDao.dicon");
}
[Test, S2(Tx.Rollback)]
publicvoid GetEmployee()
{
ReadXlsWriteDb("Seasar.Examples/Reference/S2Unit/GetEmployeePrepare.xls");
Employee emp = dao_.GetEmployee(9900);
DataSet expected = ReadXls("Seasar.Examples/Reference/S2Unit/GetEmployeeExpected.xls");
S2Assert.AreEqual(expected, emp, "1");
}
publicvoid Main()
{
using (MainClass mc = new MainClass())
{
mc.Main(newstring[] { "Seasar.Examples.exe" });
}
}
}
}
Excecute Seasar.Examples. To start testing, select S2Container Reference from the tree. Select Test on Select query(3).
Test may be executed from the console by executing MbUnit, but it is easier to use MbUnit.GUI.exe and TestDriven.NET.
SetUpGetEmployee() as app.dicon.
S2Assert.AreEqual() method compares the DataSet with IList of IDictionary and IDictionary, object, and IList of object.
ReadXlsWriteDb() method and ReadXlsAllReplaceDb() methods are used to write test data to the database.
If Excel file is in the same namespace as the test class, namespace may be omitted from the path. (However, it is necessary to use build event to output to the same folder as the assembly.)
To rollback after each test, execute ReadXlsWriteDb() andReadXlsAllReplaceDb() at the beginning of the test method.
Execution result are compared with data in an Excel sheet.
By passing data retrieved from Dao and verification data in Excel sheet retrieved from ReadXls() method to the S2Assert.AreEqual() method, data retrieved from Dao is converted to DataSet and is used in comparison with data from the Excel sheet.
S2Unit.NET reads sheet in alphabetical order and not in the order they are defined in the Excel sheets as in S2Unit.Java.
If there is an error due to foreign key constraint, prefix sheet name with "#". For example, to insert data from the emp table into the third sheet, name the Excel sheet "#3 emp".

- Provide an enumeration for the different types of session events.
-
- Classes:
-
-
- Description:
bmqt::SessionEventType
is an enumeration for the different types of session events.
-
CONNECTED: The connection with the broker is established, this event is only fired once (if for any reason the connection gets lost and automatically reconnected, this will emit a
CONNECTION_RESTORED
event).
-
DISCONNECTED: The connection with the broker is terminated (after the user called stop on the session). This is the last event that will be delivered.
-
CONNECTION_LOST: The session was connected to the broker, but that connection dropped.
-
RECONNECTED: The connection to the broker has been re-established. This event is followed by zero or more
QUEUE_REOPEN_RESULT
events, and one STATE_RESTORED
event.
-
STATE_RESTORED: Session's state has been restored after connection has been re-established with the broker. This event is preceded by one
RECONNECTED
event, and zero or more QUEUE_REOPEN_RESULT
events.
-
CONNECTION_TIMEOUT: The connection to the broker has timedout.
-
QUEUE_OPEN_RESULT: Indicates the result of an
openQueue
operation.
-
QUEUE_REOPEN_RESULT: Indicates the result of an
openQueue
operation, which happens when the connection to the broker has been restored and queues previously opened have been automatically reopened. This event is preceded by a RECONNECTED
event and followed by zero or more QUEUE_REOPEN_RESULT
events, and one STATE_RESTORED
event.
-
QUEUE_CLOSE_RESULT: Indicates the result of a
closeQueue
operation
-
SLOWCONSUMER_NORMAL: Notifies that the EventQueue is back to its low watermark level.
-
SLOWCONSUMER_HIGHWATERMARK: Notifies that events are accumulating in the EventQueue, which has now reached it's high watermark level.
-
QUEUE_CONFIGURE_RESULT: Indicates the result of a
configureQueue
operation.
-
HOST_UNHEALTHY: Indicates the host has become unhealthy. Only issued if
a bmqpi::HostHealthMonitor
has been installed to the session, via the bmqt::SessionOptions
object.
-
HOST_HEALTH_RESTORED: Indicates the health of the host has restored,
and all queues have resumed operation. Following a Host Health incident, this indicates that the application has resumed normal operation.
-
QUEUE_SUSPENDED: Indicates that an open queue has suspended operation:
* Consumers are configured to receive no more messages from broker (i.e., maxUnconfirmedMessages := 0, maxUnconfirmedBytes := 0, consumerPriority := INT_MIN). * Attempts to pack messages targeting queue will be rejected by bmqa::MessageEventBuilder::pack()
. Clients may still attempt to POST existing packed events. * Attempts by client to reconfigure queue will not take effect until the queue has resumed.
-
QUEUE_RESUMED: Indicates that a suspended queue has resumed normal
operation (i.e., effects of QUEUE_SUSPENDED state no longer apply).
-
ERROR: Indicates a generic error.
-
TIMEOUT Indicates that the specified operation has timed out.
-
CANCELED: Indicates that the specified operation was canceled.

With the help of Chip and Joanna Gaines, a family undertakes a one-of-a-kind project in the rolling hills outside Waco, TX -- and simultaneously the term "barndominium" is added to our design lexicon. In this notably non-traditional Fixer Upper , a barn conversion turns a 1000-square-foot attic apartment -- along with horse stalls and hay storage -- into an amazing 2700-square-foot home with contemporary styling and a truly spectacular dining space.
Meet Magnolia: we’re all about the home. Owned by Chip and Joanna Gaines from HGTV’s Fixer Upper, we’re a small town business deep in the heart of Texas inspiring folks from all walks of life to take ownership of their spaces and create value where they’re planted.
Chip and Jo move walls, rooms and one very large fireplace to help give a pure '70s home a sleek and updated look that suits its beautiful setting.

First things first, you'll need the dependencies:
<script src="app.js"></script>Then, you'll have to initialize a client with a configuration:
var client = new ZendeskSearch({ host: 'http://hostname:9200/', index: 'index-name' });With that object in hand, you'll be able to find tags:
/* Find all tags */ client.search('*', function(results) { for (var index in results['results']) { console.log('Found ' + results['results'][index]); } });And of course, you'll be able to add tags:
/* Add a tag called foo */ client.add('foo', function(obj) { console.log(obj); });And if you ever tire of the tags, you can of course, delete them:
/* DELETE! DELETE! DELEEEEETE! */ client.remove('foo', function(obj) { console.log(obj); });

The many temples, forts, palaces and monuments in the country make up the historical places of India. These reflect the splendid heritage and culture of the country. The historical places in India depict the stunning craftsmanship on the stone which can be seen in many temples and forts. The Taj Mahal, Red Fort, Humayun's Tomb are famous historical monuments of the Mughal period. Champaner, Dholavira and Nalanda are ancient archaeological sites. Glimpses of colonial architecture can be seen in cities such as Goa, Kolkata and Pondicherry. The Great Living Chola Temples are another example of India's rich history. Konark, Mysore, Orchha, Hyderabad, Bijapur and Lucknow are few other cities that are of historical significance.
One of the Seven Wonders of the World, the Taj Mahal is undoubtedly India's most famous monument. It looms evocatively from the banks of the Yamuna River. Mughal emperor Shah Jahan had it built as a mausoleum for third wife, Mumtaz Mahal, who died in 1631. Construction took place over 16 years, from 1632 to 1648.

Hampi is a backpacker's paradise, the same way a pilgrim's delight.
load moreThe Red Fort Complex was built as the palace fort of Shahjahanabad – the new capital of the fifth Mughal Emperor of India, Shah Jahan. Named for its massive enclosing walls of red sandstone, it is adjacent to an older fort, the Salimgarh, built by Islam Shah Suri in 1546, with which it forms the Red Fort Complex. The private apartments consist of a row of pavilions connected by a continuous water channel, known as the Nahr-i-Behisht (Stream of Paradise).

Husky Checkout is an app that allows students to check out IT equipment quickly and efficiently to save time for students and staff. In collaboration with the University of Washington-Bothell (UWB) IT department, we identified ways to improve the checkout system by removing the paper checkout process and developed an electronic system.
What were the challenges that the staff and students faced with the last system? How can we improve the overall equipment checkout process so that it is less time consuming and tedious?

To understand the current checkout system, we completed a contextual inquiry by shadowing the IT staff and observing the checkout process for the faculty and students. Based on our research, we developed a journey map to understand what students and staff need to complete the checkout equipment.
Click Here to view a larger version of the journey map.
To further our understanding, we created cultural probe kits for the staff to track their thoughts and feelings about the check out process for 7 days. We analyzed their feelings and conducted follow up interviews based on their responses.
Click Here to view an in-depth analysis of the cultural probe.
We interviewed 3 different UW IT Department staff that completed our cultural probe kits to learn more about their motivations and pain points.
Click Here to view an in-depth analysis of the interviews
Based on our findings from the cultural probe kit and interviews, we intend to create a software application to minimize the staff's repetitive nature of the work to make checking out equipment quicker to reduce some of the stress associated with it.
We created a paper prototype to test the user flow of the app with other students in the class. We found that giving users the option to customize was unnecessary and we focused on the student's experience using the app.
I updated the UI of this app to make it more visually appealing and focused on improving the user flow.
User need: User needs to get recommendations about different equipment so they can pick equipment that fits their needs.
User need: User needs to feel familiar with a new interface so they do not feel overwhelmed using the app.
Responses: Users can check out equipment with fewer clicks compared to the previous iteration of the checkout system. Users are familiar with shopping commerce websites by adding items to cart to check out equipment (think Amazon). The catalog on the app removes out of stock items and simplifies the information about the equipment. Lastly, the final interaction has an email notification for students to know when items are due so staff can predict their equipment inventory.
Develop analytic measurements system within the app to help inform the design refinements of Husky Checkout feature that will better serve the user needs.
Test the prototype of the app with students to see if it reduces the
amount of stress and repetitive nature of UW IT Department staff.
Hope you enjoyed checking out my work, as much as I had fun making them.

Variables are containers for storing data values (including numbers and strings), that can be reused over and over again.
Variable names are case sensitive, meaning that “Variable” and “variable” are not going to have the same value.
Value of a variable can be:
myVariable
or /$myVariable$/
50
"My Cat"
[2]myStack
(myVariable * 10 - [2]myStack + 3)
All variables inside Receiver are global and get deleted every time you close or reset Receiver.
Variables are not unique to a button that created them and any button/deck can access them.

Java Class
Java is designed to be an object oriented language
for deploying secure, multithreaded network applications (both clients
and servers). Prolog is ideal for building intelligent components, expert
systems and logic-bases.  The Java
Class encapsulates the Amzi! Logic Server for use by Java applications
and applets. It includes:
-
A Java Class Package the encapsulates a Logic Server Engine
-
Methods that correspond to the Logic Server API Functions
-
Use of Java's exception handling for API errors, and
-
Java-like method interfaces.
The Java Logic Server methods are documented in the LSAPI
Reference.
In addition, you can extend the Java Class to allow Prolog to call methods
in your Java code.
The sections of this document are:
Where to Learn
About Java
If you want to learn more about Java and Java Applets and JSP/Servlets, see java.sun.com.
You can also download Sun's Java Development Kit (JDK) from there.
Installation
The Java Class and its samples are distributed for JDK 2.0.
To use the Java Class, you must make these files accessible to the calling
environment:
- Amzi! Dynamic/Shared Library - The Amzi! Logic Server, amzi.dll
or libamzi.so, and the Amzi! Java interface, amzijni.dll, must be in your
PATH or otherwise accessible to the calling environment. These files are in
the amzi/\bin directory. You can load these libraries (and LSXs) explicitly
in Java with Runtime.getRuntime().load(libraryPath) or loadLibrary(libraryName).
- Amzi! Java Classes - The amzi/ls directory structure, containing
the amzi.ls.* package must be accessible via your CLASSPATH. You can do this
by adding amzi/lsapis/java20 to your CLASSPATH or copying the amzi/ls subdirectory
structure to a directory already in your CLASSPATH.
Do not put any other
files in your amzi/ls directory as they will be included when you import amzi.ls.*;
and may cause naming conflicts.
Hello Prolog
To make sure the Amzi! Java interface is ready to use, run the Amzi! Hello sample
for Java. It is in the directory amzi\samples\java\hello. To build the Hello program
from Java, first open a 'DOS' window and change to the sample directory containing
Hello.java. To compile it, type:
javac Hello.java
This will produce Hello.class which is simply run by typing:
java Hello
Overview
The Java Class is implemented using the Java Native
Interface (JNI). This allows methods used in a Java class to be implemented
in C/C++. In the case of Amzi!, the JNI is used to build a bridge to the
Logic Server API, which is the external interface on the Amzi! Prolog engine.
The bridge is necessary because many of the Logic Server API functions
have to be changed slightly to conform to Java parameter passing and return
conventions (such as accommodating the lack of pointer support in Java).
So, the Amzi! Java interface defines a Java class, LogicServer, whose methods
are implemented by calls to C/C++ functions in a dynamic/shared libary that,
in turn, calls the main Amzi! engine dynamic/shared library. This is illustrated
in Figure 1.
Figure 1
Working right to left in the diagram, amzi.dll is the Amzi! Logic Server (Prolog
engine). amzijni.dll/libamzijni.so is the interface library that implements
the Java versions of Logic Server API functions. Those, in turn are wrapped
in the Java classes, LogicServer and LSException.
Object Oriented
The Amzi! Logic Server is implemented as an object oriented program, so that each
Logic Server is an object and the Logic Server API functions are methods of that
object. It is natural, therefor, to provide object oriented interfaces to the
Logic Server for object oriented languages such as Java. (Amzi! is also available
in a .NET, C++ and Delphi class.) The Logic Server class can then be used as any
other class in an object oriented application, supporting, for example, subclassing,
embedding and multiple instances. This makes for an elegant approach to encapsulating
Prolog services in applications. (see "Objects
and Logic-C++ Meets Prolog", PC AI May/Jun 95)
Figure 2 is an expanded architecture diagram that illustrates the package
and its classes.
Figure 2
Representing Prolog
Terms
A fundamental data type for the Prolog interface is a Prolog term. Internally,
a Prolog term is a pointer, but, since that pointer is not manipulated by the
application, it can be stored as an integer. For Java, it is stored in a 64-bit
integer so Java can support both 64- and 32-bit versions of the Amzi! Prolog engine.
Issuing Prolog
Queries
The base LSAPI functions that issue Prolog
queries return TRUE or FALSE, corresponding to Prolog success or failure,
and use a pointer to the calling Prolog term to pass back the term resulting
from the query. For example a function issuing the query 'available(com,
Port)' will return true or false plus the term representing the query with
the Port variable unified with the result.
For Java, the query LSAPI functions (Exec, ExecStr, Call, CallStr) return
the term (a long) directly, instead of a true false. If the query fails,
that is indicated by a zero (0) value returned. (Errors are indicated by
LSExceptions.)
String Conversion
The Java LSAPI automatically converts
the internal Unicode Java representation of character strings to and from
the Amzi! internal Unicode representation.
 The LSException class
is thrown when an error occurs. LSException contains a number of methods
for learning details about the exceptions.
Multi-Threaded
Java allows you to start multiple threads
in the same program, and Amzi! supports multiple simultaneous Prolog engines.
So each instance of the Java Logic Server class will contain its own Prolog
runtime environment.
Using the Java Class
To use the LogicServer class you import the amzi.ls
package into your Java program:
import amzi.ls.*;
From there you can either instantiate a new LogicServer object and invoke its
methods, or you can define a new class that extends the LogicServer class adding
new methods and variables.
Implementing
Extended Predicates
Java, like C/C++, Delphi and VB 5.0 (and later),
can be used to implement custom extended predicates to the Prolog language. These
custom extensions give the Prolog code the ability to directly access anything
Java can access.
The Java methods that implement extended predicates, must be declared as returning
type boolean, and as public. They can be added one at a time using the API function
AddPred, which adds a single predicate at a time. If your extended predicate
is in a package, then the package name must be included in the class name, delimited
by forward slashes, to AddPred as follows:
ls.AddPred("extpred", 1, "javapkg/jprolog", "extpred", this);
The parameters are:
- Predicate Name
- Predicate Arity
- Java Class Name (fully qualified including packages)
- Java Method Name
- Pointer to the Instance of the Class Object that contains the Method
Note: Extended predicate definitions
must always be added after calling InitLS and before calling LoadXPL.
The sample in directory /samples/java/pets_callback is an example of how to
implement an extended predicate in Java.
Using Static Methods as Extended Predicates
You can use static methods as extended predicates by specifying null for the pointer to the instance of the class. Static methods are a good choice when pooling Logic Servers in a Web application.
Controlling the JNI Environment Pointer for Extended Predicates
More complex applications may require finer control over the JNI environment pointer that is used to locate and call extended predicates. AddPred can be called with an additional parameter that specifies this, for example:
ls.AddPred("extpred", 1, "javapkg/jprolog", "extpred", this, LogicServer.ADD_PRED);
There are three options:
- ADD_PRED — This uses the JNI environment pointer when AddPred is called. For this to work, the thread that called AddPred() needs to be the same thread that is calling the extended predicate.
- CURRENT_THREAD — This uses the JNI environment pointer for the currently executing thread.
- EXEC_OR_CALL — Not recommend. This option is available for backwards compatibility. It will not work in a multi-threaded environment. It uses the JNI environment pointer from the last Exec(), Call() or Redo(). This pointer is saved in a global variable for all threads using the Amzi! JNI Interface.
Note: Extended predicates will fail (return false) if you use CURRENT_THREAD and the current thread is not attached to the Java virtual machine.
Converting Prolog
Lists to Java Types
Here are some useful Java methods that convert Prolog lists. The first takes
each item in a Prolog list, converts it to a string and saves it in a String
array.
public static String[] prologListToStringArray(LogicServer ls, long list, int size) throws LSException
{
List array = new ArrayList();
// Check for the empty list or an atom
long type = ls.GetTermType(list);
if (type != LogicServer.pLIST) return new String[0];
while (list != 0) {
array.add(ls.TermToStr(ls.GetHead(list), size));
list = ls.GetTail(list);
}
String[] result= new String[array.size()];
array.toArray(result);
return result;
}
This method takes a Prolog list of the form [name1 : value1, name2 : value2...
nameN: valueN] or [item(name1, value1), item(name2, value2)...item(nameN, valueN)]
and converts it to a Java Properties list where the property name and value.
public static Properties prologListToProperties(LogicServer ls, long list, int size) throws LSException
{
Properties p = new Properties();
long element, name, value;
// Check for the empty list or an atom
long type = ls.GetTermType(list);
if (type != LogicServer.pLIST) return p;
while (list != 0) {
element = ls.GetHead(list);
name = ls.GetArg(element, 1);
value = ls.GetArg(element, 2);
if (ls.GetTermType(value) == LogicServer.pLIST)
p.setProperty(ls.TermToStr(name, size), ls.TermToStrQ(value, size));
else {
p.setProperty(ls.TermToStr(name, size), ls.TermToStr(value, size));
}
list = ls.GetTail(list);
}
return p;
}
