Get started with an easy, short example that showcases the major features of DotNet.Safe.
First, we'll take a look at some preexisting code.
public void ViewShipmentDetails() { try { Console.WriteLine("These are the active shipments:"); foreach(var entry in Database.GetActiveShipments()) Console.WriteLine(entry.ToString()); } catch(Exception ex) { Console.WriteLine("Active shipments couldn't be recovered."); return; } Console.WriteLine("Please enter the shipment number:"); int shipmentNumber; if(!int.TryParse(Console.ReadLine(), out shipmentNumber)) { Console.WriteLine("Shipment number is invalid."); return; } try { var shipmentDetails = Database.GetShipmentDetails(shipmentNumber); Console.WriteLine("Details for the selected shipment:"); Console.WriteLine(shipmentDetails.ToString()); } catch(Exception ex) { Console.WriteLine("Shipment details couldn't be recovered."); return; } }
This code represents a basic application that allows the user to see the details of a shipment. First, it will present a list of active shipments to choose from. Then, the user will enter the number of one of those. After a database query, the details of the shipment are printed on the console.
As each of the stages can fail, exception handling code is splatered everywhere, making the code messy and difficult to read.
We will now start fixing this code to make it cleaner, safer and more modular.
Let's start by separating the steps into different methods.
Instead of having the entire logic in one method, we'll move the four steps (show active shipments, ask for shipment number, query the database, show shipment datails) into their own methods. That will improve code quality by making each method perform only one task.
This is how it looks like after that change:
public void ViewShipmentDetails() { try { ShowActiveShipments(); var shipmentNumber = AskForShipmentNumber(); var shipmentDetails = Database.GetShipmentDetails(shipmentNumber); ShowShipmentDetails(shipmentDetails); } catch(Exception ex) { } } private void ShowActiveShipments() { try { Console.WriteLine("These are the active shipments:"); foreach(var entry in Database.GetActiveShipments()) Console.WriteLine(entry.ToString()); } catch(Exception ex) { Console.WriteLine("Active shipments couldn't be recovered."); throw ex; } } private int AskForShipmentNumber() { Console.WriteLine("Please enter the shipment number:"); int shipmentNumber; if(!int.TryParse(Console.ReadLine(), out shipmentNumber)) { Console.WriteLine("Shipment number is invalid."); throw new Exception(); } return shipmentNumber; } private void ShowShipmentDetails(ShipmentDetails details) { Console.WriteLine("Details for the selected shipment:"); Console.WriteLine(shipmentDetails?.ToString()); }
Now that the steps are separated, it's easier to make changes and update the code. Note that we still need a try-catch in the main method, as a failure in any of the steps means that none of the next steps can be executed.
That problem will be fixed in a moment. First, let's check a small requirement.
In order to chain the steps into a composition, they must adhere to one rule.
Before we start using a composition to execute the steps, we must make sure they are composable. A set of steps is composable if the return value of a step is the parameter for the next .
In this case, the steps are valid for composition, as they follow that rule:
Should a set of steps not fit in this rule, you'll have to modify them in a way that makes them composable prior to using DotNet.Safe to execute them. Note that, as an exception to this rule, return values can be ignored. Thus, a step that returns something can be followed by a step that receives no parameters. In that case, the return value of the preceeding step will be discarded.
We're all set! This is where the magic happens.
As the steps are ready to be composed, the process is really simple.
First, remove all exception handling code, and leave only the actual logic of the process at hand. It will look like this:
public void ViewShipmentDetails() { ShowActiveShipments(); var shipmentNumber = AskForShipmentNumber(); var shipmentDetails = Database.GetShipmentDetails(shipmentNumber); ShowShipmentDetails(shipmentDetails); } private void ShowActiveShipments() { Console.WriteLine("These are the active shipments:"); foreach(var entry in Database.GetActiveShipments()) Console.WriteLine(entry.ToString()); } private int AskForShipmentNumber() { Console.WriteLine("Please enter the shipment number:"); return int.Parse(Console.ReadLine()); } private void ShowShipmentDetails(ShipmentDetails details) { Console.WriteLine("Details for the selected shipment:"); Console.WriteLine(shipmentDetails?.ToString()); }
Now substitute the current calls in the main method with a composition using the Try class.
Start it by calling Try.This(), and passing the first step as parameter. Append the following steps with .Then() and finalize the composition with a call to .Now()
public void ViewShipmentDetails() { Try.This(ShowActiveShipment) .Then(AskForShipmentNumber) .Then(Database.GetShipmentDetails) .Then(ShowShipmentDetails) .Now(); } private void ShowActiveShipments() { Console.WriteLine("These are the active shipments:"); foreach(var entry in Database.GetActiveShipments()) Console.WriteLine(entry.ToString()); } private int AskForShipmentNumber() { Console.WriteLine("Please enter the shipment number:"); return int.Parse(Console.ReadLine()); } private void ShowShipmentDetails(ShipmentDetails details) { Console.WriteLine("Details for the selected shipment:"); Console.WriteLine(shipmentDetails?.ToString()); }
We could ship it as it is, but it's usually polite to report errors.
The composition is already working, and will execute the steps in order until it finishes or one of the steps fail. If that happens, the remaining steps are ignored and the error is propagated forward.
In its current state, the composition won't tell the user anything if the steps fail. Users will likely appreciate some feedback, so we must add that functionality.
To achieve this, use the .Otherwise() method. You can add calls to Otherwise between the steps, in any number or combination. They will only be executed if the composition has failed by the time it reaches the call. If it's successful, it will simply ignore those calls.
Note that, after the first Otherwise step is executed, the rest of them are also skipped. This prevents unrelated error handlers to try and fix steps that weren't even executed.
Otherwise takes a System.Exception object as a parameter, normally containing information on the reason for failure.
The number of Otherwise calls to be used depends on the level of granularity you want for error reporting. You can add one at the end for a high-level report, such as:
public void ViewShipmentDetails() { Try.This(ShowActiveShipment) .Then(AskForShipmentNumber) .Then(Database.GetShipmentDetails) .Then(ShowShipmentDetails) .Otherwise(exc => Console.WriteLine(exc.Message)) .Now(); }
Or, if you prefer, add several calls to report lower-level information:
public void ViewShipmentDetails() { Try.This(ShowActiveShipment) .Otherwise(exc => Console.WriteLine($"Active shipments couldn't be recovered: {exc.Message}")) .Then(AskForShipmentNumber) .Otherwise(exc => Console.WriteLine($"Shipment number is invalid: {exc.Message}")) .Then(Database.GetShipmentDetails) .Otherwise(exc => Console.WriteLine($"Shipment details couldn't be recovered: {exc.Message}")) .Then(ShowShipmentDetails) .Now(); }
Now you should be able to use DotNet.Safe to adapt basic applications. For more details, check the rest of the documentation.


A selector is a Prolog term denoting a (path to a) subterm of a given term T. Let subterm(T,S) denote the subterm of T wrt. a selector S, and let N denote an integer. A selector then takes one of the following forms:
| S | subterm(T,S)
|
[] | T
|
[..., N] | Nth argument of the compound term subterm(T,[...] )
|
[...,# N] | Nth element of the list subterm(T,[...] )
|


This demo uses Juniper library to run code on mybinder.org. The code uses twarc to get the latest tweets about a search query, using the Twitter API.
The demo is safe for using the API, as it circumvents the cross-origin request limitation of the Twitter API, because of which one cannot directly get the response the Twitter API in browser side javascript code.
Another usability issue which I have addressed here is to save the twitter credentials in the client's localStorage, which makes using the page on a refresh much easier. The local storage is also used to save the JSON data returned by the API. This ensures that the page is not making multiple requests to fetch the same data.
sctg_data
. If the data from a previous iteration is available the status line will show its size and search query used.Save credentials
button. This will create a code block with the Run

Preface
\r\nEveryone agrees that writing
clean ruby code is essential. There are many blog posts about refactoring your
ruby code to make it more readable and maintainable. As tests become a major part
of our programming routine, I feel there is a large place for improvement in the
way we write and maintain our test-suites. Many ruby projects consist of more
rspec lines than actual ruby code, and that requires us to treat our test code
with as much care as we treat our actual ruby code, if not even more. Writing
specs may be considered by programmers as a burden or a chore if not done the
right way. That may cause some programmers to write less specs for their code
or to even totally give up on it. Luckily, RSpec provides us with all the tools
necessary to create efficient, great looking and fun-to-write specs for our code.
I'd like to go over a process of refactoring a test-suite written in RSpec for
a small library I've recently written in FTBpro.com.\r\n
The Domain
\r\nIn
FTBPro we have posts written by users, and
a dynamic set of reaction templates that allows the user to react to that post.
A post has a locale and a type, reaction templates has a locale and an array of
types which they fit to. When a new post is created, we want to attach the most
suitable reaction template to it:\r\n
\n- It must have the same locale as
the post.
\r\n\t- Its types array must include the post's type.
\r\n\t- From
the set of matching reaction templates by rules 1 and 2, choose the one which
was created the latest.
\r\n
\r\nI came out with the following interface
to do this job:\r\n
FindReaction.for(post).attach
\r\nWhile\r\n
FindReaction.for(post).reaction\r\n
holds
the reaction which was found - I mainly exposed this for tests purposes.\r\n\r\nNow
the funny part about this blog post is that I'm not going to post here the code
which implemented this logic, we shouldn't even care about it. What I'm going
to do is to present you with a messed up test suite for this logic, and lead you
through the process of making it a blast.\r\n\r\nThis test suit contains 4 simple
specs which describe the behavior we expect from FindReaction:\r\n\r\nhttps://gist.github.com/erez-rabih/6697511\r\n\r\nAlthough
these specs pass they're not optimal. Let's follow these rules of thumb to make
this spec a blast!\r\n
Rule #1: Keep your specs DRY - use before blocks
\r\nThe
first line of each spec is identical - we create a post. It should be extracted
to a before block so we don't have to mention it over and over again.\r\n
Rule
#2: Use before :all instead of before :each when possible
\r\nWhy should we
create the post before each spec runs? If you're not changing your model's attributes
between specs, you should definitely use before :all.\r\nA note on this: unlike
before :each blocks which are wrapped in a DB transaction and thus getting rollbacked
after the spec is executed, before :all blocks have to be cleaned explicitly so
that you don't fill your test DB with garbage.\r\n
Rule #3: Use build instead
of create when possible
\r\nWe're using FactoryGirl to create a post. Creating
is an expensive operation: The post has to go through validations, we save it
to the DB and in many cases it requires other models to be created as well. For
example, if part of a post validation says it has to have a user than we'll create
a user as well. By building a post instead of creating we save all this time and
get the same outcome.\r\n
Rule #4: Use describe to create nested specs groups.
describe should relate to an operation or an object.
\r\nWe're actually testing
here 2 different methods of FindReaction. Specs 1-3 describe the reaction method
while spec #4 describes the attach method. Each of these methods should have its
own describe block.\r\n
Rule #5: Use variables instead of constants to keep
your specs from becoming too fragile.
\r\nIn lines 19-21 we create reaction
templates and we want their locale to match the created post's locale. Instead
of using the string \"en\" again and again we should use post.locale\r\nThis makes
your spec less fragile so that if someday someone changes the post's locale, he
won't have to change the reaction templates creation as well.\r\n
Rule #6:
Use RSpec's magnificent be_ syntactic sugar
\r\nRSpec has many syntactic sugars
that makes your specs more readable. Let's look at line 6 for example:\r\n
reaction.blank?.should
== true
\r\nWhen an object reacts to some_method_name? RSpec allows you
to write the test in the following way:\r\n
object.should be_some_method_name
\r\nOr
in our case:\r\n
reaction.should be_blank
\r\n
\r\n
Rule
#7: Use create! and save! instead of create and save
\r\nWhen creating or
saving models to your DB, use create! and save! instead of create and save.\r\nThe
difference is that the bang version of the methods throws an exception if the
operation fails, while the non-banged versions just return false. I wasted a lot
of time debugging failed specs only to find out the model was not saved or created
due to validation or another problem. By using create! and save! you'll be sure
that the model was created successfully and it exists for you to test it, otherwise
an exception will be thrown and you'll know about it immediately.\r\n
Midway
\r\nAfter
applying these 7 simple rules our spec following already looks much better:\r\nhttps://gist.github.com/erez-rabih/6698414\r\nYou
might think to yourself \"OK, this looks great\", but I've got a surprise for
you: The interesting part is only ahead of us. Let's take the extra leap to improve
our specs even more.\r\n
Rule #8: If/When rule of thumb
\r\nWhen there
is a \"if\" or \"when\" in your it \"should ...\" clause, there's a hidden context
in it.\r\nLooking at spec #2 our it clause looks like this:\r\n
it \"should
return no reaction template if reaction templates exist, but non fitting\"
\r\nThere's
an
if in it, and that's exactly what we're looking for. If or
when mean you're describing a state. These states should be extracted to a context
block with a before block describing the state. After applying this rule spec
#2 should look like this:\r\nhttps://gist.github.com/erez-rabih/6698523\r\n\r\nWe
should apply the same to specs 1,3 and 4\r\n
Rule #9: Use subject/it clauses
to keep your specs DRY'er and cleaner
\r\nWe can easily identify that specs
1,2 and 3 all test the same result:
FindReaction.for(@post).reaction
\r\nThis
can be easily extracted into
subject {FindReaction.for(@post).reaction}
phrase which does miracles to our test code.\r\n
Rule #10: One assertion
per test case
\r\nI like to have only one assertion in each spec. This way
if the spec fails, you immediately know what went wrong and don't even have to
look at the detailed output of the failure. It also keeps your specs clean and
focused on what they're supposed to test. Spec #3 has two assertions in it, in
the first we check that a reaction is found and in the second we check what specific
reaction was found. These are two completely different assertions and deserve
different specs. The one assertion per spec rule is easily achieved with combination
of Rule #9, we'll see why right away.\r\n
Rule #11: Use RSpec's expect {} block
to describe a change in the state of an object
\r\nIn spec #4 we test that
the post's reaction_template has changed from nil to the attached reaction. RSpec
has a nice and clean way to describe these kind of state changes:\r\n
expect
{ some_operation }.to change{something}.from(initial_value).to(final_value)
\r\nIt
is much cleaner and more readable this way.\r\n\r\nThis is the result after applying
rules #8-#11 to our spec:\r\nhttps://gist.github.com/erez-rabih/6698783\r\n
Conclusion
\r\nSo
what have we earned in this refactoring process? I'll point the main advantages
of the new code:\r\n
\n- Our test-suite runs faster
\r\n\t- Our test
file is more readable
\r\n\t- The failure output provided by RSpec is better
\r\n\t- We're
not repeating ourselves between specs
\r\n\t- It is extremely easy to extend
the specs to describe new features
\r\n\t- I find it much more enjoyable
writing specs that looks cool (And you must admit, it does look cool).
\r\n
\r\nI
know that even this code can be optimized and refactored, but I had to stop somewhere
:)\r\nI'll be glad to hear your insights and thoughts.\r\n\r\n* This post was

Pomade is buried deep in the aesthetic canon of classic Americana, right next to straight razors and Clubman talcum powder. Near forgotten, this old-school staple is making a resurgence thanks to young barbers that value its unique combination of finish and hold. It marries the wet aesthetic of gel with the pliability of wax. Traditional pomades are oil-based. Purists argue that styles will last longer with this class of product, but scalps be warned — oil-based pomades are notoriously harsh and take multiple washes to remove. The new trend in grooming is water-based pomades, which can be stripped with a single rinse and still offer a range of control. So whether you’re after a sleek side-part, or prefer it naturally matte with a touch of texture, these are the best pomades to try now.
— Contribution by Jack Seemer and John Zientek
Suavecito was started with the goal of providing a high-quality, no-nonsense pomade at an affordable price. This strong-hold pomade will tame the unruliest hair, but will wash easily at the end of the day. It’s made here in the United States and has superlative reviews across the board.
Base:Water
Hold: Strong
Shine: Medium
Founded by two Australian barbers, Uppercut Deluxe makes hair grooming products inspired by one of their own grandfathers, Willy “Uppercut” O’Shea, an emigrant boxer known to dress above his pay grade. Among the several exceptional products in their line, the Deluxe Pomade is the all-around standout with a sweet vanilla aroma and firm hold that’s easy to wash out.
Base: Water
Hold: Strong
Shine: Medium
California brand Layrite created a versatile pomade that offers a firm hold with an easy removal process. Superhold works best for coarse or thick hair and has a medium shine that works for a range of hairstyles.
Base: Water
Hold: High
Shine: Medium
Having gained traction in the custom car culture of Japan, Cool Grease products can now be found in high-end barbershops across the world. With whiffs of tropical fruit, Fiber Grease adds shine and lasting malleability for a hold that doesn’t feel too heavy.
Base: Water
Hold: Medium
Shine: Medium
This pomade has an incredibly strong hold, but is smooth to apply. It is also water reactivatable, so if your mane needs adjusting throughout the day, just add a bit of water and restyle. Imperial pomades are made in America, and have were developed by a team of barbers with over three decades of experience in the industry.
Base: Water
Hold: Strong
Shine: Medium
A trusted stalwart among longtime pomade wearers, Black & White was once said to dress the hair of famous Hollywood stars including James Dean. For an oil-based pomade, it’s lightweight, working easily into the hair without sacrificing on longevity or hold.
Base: Oil
Hold: Medium
Shine: Medium
Dax Wave and Groom, the most orthodox pomade on this list, comes in the classic aluminum tin, costs close to nothing, and laps on strong and heavy for a lasting product that’ll keep your hair neat from morning ’til night (and probably the next one too). This wins out over Murray’s any day of the week.
Base: Oil
Hold: Strong
Shine: High
Infused with beeswax and clay, this pomade is strong and pliable while retaining a matte finish. It’s a great product for disheveled, messy hair styles, though it can be used to achieve a variety of results. The award-winning paraben-free formula will give you an all-day hold that can be retooled as needed.
Base: Oil
Hold: Strong
Shine: Low
This classic pomade works for a variety of hair types and delivers an exceptional amount of shine, and pliable hold. It’s a workhorse product that can create iconic slicked-back looks, or just add additional hold to whatever style you’re wearing. What’s more, it’s easy to find and is a staple product at supermarkets and drugstores.
Base: Water
Hold: Medium
Shine: High

Agave is a library designed to enable rapid web application development through the use of handlers that field HTTP requests. The handler methods are self-describing and need no more configuration information beyond the method-level annotations that identify handlers and indicate how to treat user input. During initialization of the context, the {@code /WEB-INF/classes} directory is scanned for all handlers and they are registered after they have been recognized.
This all happens with the classes and annotations from the {@link agave agave} package. The javadoc in that directory will serve as a good starting place for more information. Another point of interest will be the {@link agave.conversion agave.conversion} package, which will describe how form objects will have input converted from a string into a higher-order object.

There are many personal values that I identify with to a certain degree but if I was to reduce it down to the core in no particular order they would be;
Open mindedness
Spirit of adventure
Positivity
Compassion
Perseverance
Loyalty
When I think about many of the important decisions that I have made in my life and the thought process behind them I see these values influencing those decisions time and time again. I believe that being openminded is fundamental in helping you grow, every day is truly a school day and your education is never finished.
Life exists outside of your comfort zone. It is only when you leave comfort behind that you can experience the full palette of emotion that life has to offer. These new experience and challenges will help you to learn about yourself, what you are capable of and lead you to become a more rounded and hopefully a better person.
I believe in the power of staying positive. I try to achieve this through perspective and gratitude. For me being positive is something that I have tried to develop and get better with practice.
Be kind, you never know the struggles that someone else is going through. Theres a reason it feels satisfying to help someone. We are altruistic and compassionate animals by nature.
I believe that hard work and perseverance are the key to success. There is a satisfaction that comes from completing something that was achieved with hard work that is unlike anything else.
Working in customer service I was often tasked with making tough ethical decisions which would directly affect a customer. My process for making such a decision always began with one question that I would ask myself. “What’s the right thing to do?” Not the easiest or the most convenient but the right thing. Using this as a starting point would provide guidance when making a tough decision. My next step would be to put myself in the customers shoes and ask how I would feel if I was in their situation? Thinking about this would usually allow me to reach a decision on how to proceed.
I come from a very working class city in the north of England. The people from this area are known for being very down to earth and hardworking. These are traits that I try and carry with me.
I consider myself to be quite disciplined and determined. If I have a task or a goal I want to achieve I can usually figure out how I want to approach it, devise a plan and stick to it without getting sidetracked easily. I don’t generally get flustered too easily and I can remain quite calm in stressful situations, I have a feeling these traits will be tested a lot during Dev Academy!
In terms of limitations I have quite an analytical personality so I can be quite demanding and self critical of myself and I sometimes set standards too high which can be quite detrimental if not kept in check.
Being a former team leader I encountered many instances of resistance or tension when trying to manage a team and work productivly. In terms of strategies I would employ to deal with this firstly I think its very important to lead by example and set the standard yourself first. If tension is arising in a work environment it can also mean that someone perhaps does not feel valued or heard so it’s important to create an inclusive environment where people do feel valued.

Protect Ports (discussed earlier) are a nice security feature of Cisco switches. When two ports are protected, they are not allowed to have direct communication with each other. But one limitation of protected ports is that they are only locally significant, so there is no way for protected ports to exist on different switches and follow the protection rules.
The Private VLAN feature was created to solve this limitation. Private VLANs are more complex and can span multiple physical switches. Private VLANs split what would normally be a single broadcast domain defined by a single VLAN into multiple isolated broadcast subdomains, that are defined by a primary VLAN and its secondary VLANs. In essence it allows us to create VLANs inside VLANs, and is not un-similar to the concept of Confederations in BGP.
Private VLANs are used to increase security. We most often see them in a shared color facility. This allows the color provider to have the customers exist on the same VLAN (and thus the same subnet), without allowing the different customers to communicate directly with each other.
One pitfall you have to remember with Private VLANs is that it requires VTP to either be in Transparent mode or to be off.
There is some terminology to remember when dealing with Private VLANs:
- Promiscuous ports are allowed to talk to all other ports within the primary VLAN
- Isolated ports are only allowed to talk with promiscuous ports
- Community ports are allowed to talk with other ports in their own community as well as any promiscuous ports, but they are not allowed to talk to ports in other communities
The configuration steps are a little unnatural as well. The port roles are defined by the interface’s association to a primary VLAN and one or more secondary VLANs. First the secondary VLANs are created and defined as either community or isolated. Then the primary VLAN is defined, and the secondary VLANs are associated with the primary VLAN.
Here is an example configuration with VLAN 500 as the primary VLAN, 501 a secondary community VLAN, and VLAN 502 a secondary isolated VLAN. Ports FastEthernet0/1 and FastEthernet0/2 are associated to VLAN 501, while FastEthernet03 and FastEthernet0/4 are associated with the secondary isolated VLAN 502.
SW1(config)# vtp mode transparent
SW1(config)# vlan 501
SW1(config-vlan)# private-vlan community
SW1(config-vlan)# vlan 500
SW1(config-vlan)# private-vlan primary
SW1(config-vlan)# private-vlan association add 501
Next, let’s go ahead and associate FastEthernet0/1 and FastEthernet0/2 to the 501 Secondary Community we just created:
SW1(config)# interface range fa0/1-2
SW1(config-if-range)# switchport mode private-vlan host
SW1(config-if-range)# switchport private-vlan host-association 500 501
Now, we can go ahead and configure FastEthernet0/24 as a promiscuous port.
SW1(config)# interface fa0/24
SW1(config-if)# switchport mode private-vlan promiscuous
SW1(config-if)# switchport private-vlan mapping 500 501
Now we turn our attention to the creation of the isolated VLAN, VLAN 502.
SW1(config)# vlan 502
SW1(config-vlan)# private-vlan isolated
SW1(config-vlan)# vlan 500
SW1(config-vlan)# private-vlan primary
SW1(config-vlan)# private-vlan association add 502
Now we must associate our interfaces:
SW1(config)# interface range fa0/3-4
SW1(config-if-range)# switchport mode private-vlan host
SW1(config-if-range)# switchport private-vlan host-association 500 502
And finally, we must add another association for our promiscuous port:
SW1(config)# interface fa0/24
SW1(config-if)# switchport mode private-vlan promiscuous
SW1(config-if)# switchport private-vlan mapping 500 502
One great way to test your Private VLAN setup is to send a single ping to the broadcast address with ping <IP_ADDRESS> repeat 1
. The replies will only be from the hosts in your broadcast domain.
One other thing to note. If you are configuring a Primary VLAN SVI to operate with secondary private VLANs, you need to map the secondary VLANs onto the SVI as in the following:
`SW1(config)# interface Vlan 100
SW1(config-if)# private-vlan mapping 1000,2000
`


Overview
An object-oriented language must fulfill the four fundamentals:
In the 1990’s a new era of object-oriented languages was introduces as C# and Java was released. They have much simpler syntax and memory management than the preceding language C++. The G# framework has taken a lot of inspiration from C# and Java and therefore has the following additional requirements:
The G# is the first LabVIEW object-oriented toolkit that really uses the mechanism of the dynamic dispatch together with the data value reference. All previously object-oriented toolkits have used some kind of common implementation in the bottom. There has been code in the classes calling the common code to create and delete objects, accessing attributes etc. However, this caused the use of a lot of unique utility VIs in all the classes.
The G# Framework has used a different approached very much inspired by the Hollywood Principle (“Don’t call us, we call you” also known as “Inversion of Control”). This means that as much as possible of the execution flow takes place in the root G#Object code and calling code in the classes by dynamic dispatch calls.
The G# Framework also have a built-in background process called “External Create Process”, if this is started, it will create and own all objects created, and also be possible to execute the default constructor and a special methods called “Open”. This way objects and its resources will not be garbage collected by LabVIEW until this process it stopped (by the Garbage Collector).


Ban Ki-Moon credits Akufo-Addo for his election as UN Secretary General
South Korean diplomat, Mr Ban Ki-Moon has expressed gratitude to President Akufo-Addo for playing a key role in his election as UN Secretary-General.
The former UN Secretary-General said he was indebted to President Akufo-Addo who as Ghana's Foreign Minister played a very good role as a campaign manager which resulted in him (Ki-Moon) winning the election on October 13, 2006.
"I take this opportunity to recognise President Nana Akufo-Addo, my longtime friend. We started as Foreign-Ministers of both countries, I visited Ghana in 2006 and I am still very much indebted for his strong political support for me to be elected as Secretary-General...," Mr Akufo-Addo said.
"...He (president Akufo-Addo) really played a very good campaign manager... Thank you very much, Mr President, I will never, never forget".
He added that President Akufo-Addo was a very committed leader who not only cares for Ghana but for Africa and the whole world.
Mr Ban Ki-Moon was speaking at the Africa Netpreneurship Summit held on Saturday in Accra.
In attendance at the event was President Akufo-Addo, billionaire Jack Ma, The Minister of Communications, Mrs Ursula Owusu-Ekuful and actor Jet Li.
President Akufo-Addo cited United Nations figures that estimated Africa’s working population in 2035 will be equal to about a quarter of the world’s total population, while a third of the world’s youth population – those between the ages of 15 and 24 – will be in Africa.
The empowerment of this population, such as through education and the regulatory environments necessary for their businesses to thrive, “will constitute very powerful tools for economic development in Africa and the world,” he said.
“Entrepreneurship is a vital component of economic growth, and has been embraced globally as one of the most important drivers of development,” said President Akufo-Addo, adding that it specifically helps to address unemployment, especially among young people.


The Blue Marble, the first full-view photograph of the planet, was taken by Apollo 17 astronauts en route to the Moon in 1972
Earth is the third planet from the Sun and the only astronomical object known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago.Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation.

This is a library that is used in order to retrieve data from the database, and cache it in order to not have expensive db call.
For example;
in the case of the Arena Service (Battle service). At the start of a battle, the contenders (monsters) that the player are facing are selected and thus known. The Service will have to fetch how the contenders behaviour are (stats, attacks, artificial intelligence and so on..), this logic is stored as chai scripts in the DB. When the battle end, if necessary, the memory is flushed for the next battle (new contenders / actions to fetch).
But in case the same contender is selected for the next fight, it would be a waster to retrieve the behaviours twice in the database.
Thanks to those 3 steps, in the second attempt to retrieve the contender data.
In order to not have not up to date scripts stored in the file system. Two mecanisms are possible:
