Amazon Redshift Overview This is an interface reference for Amazon Redshift. It contains documentation for one of the programming or command line interfaces you can use to manage Amazon Redshift clusters. Note that Amazon Redshift is asynchronous, which means that some interfaces may require techniques, such as polling or asynchronous callback handlers, to determine when a command has been applied. In this reference, the parameter descriptions indicate whether a change is applied immediately, on the next instance reboot, or during the next maintenance window. For a summary of the Amazon Redshift cluster management interfaces, go to `Using the Amazon Redshift Management Interfaces `_.
Amazon Redshift manages all the work of setting up, operating, and scaling a data warehouse: provisioning capacity, monitoring and backing up the cluster, and applying patches and upgrades to the Amazon Redshift engine. You can focus on using your data to acquire new insights for your business and customers.
If you are a first-time user of Amazon Redshift, we recommend that you begin by reading the The `Amazon Redshift Getting Started Guide`_
If you are a database developer, the `Amazon Redshift Database Developer Guide`_ explains how to design, build, query, and maintain the databases that make up your data warehouse.
alias of JSONResponseError
Adds an inbound (ingress) rule to an Amazon Redshift security group. Depending on whether the application accessing your cluster is running on the Internet or an EC2 instance, you can authorize inbound access to either a Classless Interdomain Routing (CIDR) IP address range or an EC2 security group. You can add as many as 20 ingress rules to an Amazon Redshift security group.
For an overview of CIDR blocks, see the Wikipedia article on `Classless Inter-Domain Routing`_.
You must also associate the security group with a cluster so that clients running on these IP addresses or the EC2 instance are authorized to connect to the cluster. For information about managing security groups, go to `Working with Security Groups`_ in the Amazon Redshift Management Guide .

Authorizes the specified AWS customer account to restore the specified snapshot.
For more information about working with snapshots, go to `Amazon Redshift Snapshots`_ in the Amazon Redshift Management Guide .
| Parameters: |
|
|---|
Copies the specified automated cluster snapshot to a new manual cluster snapshot. The source must be an automated snapshot and it must be in the available state.
When you delete a cluster, Amazon Redshift deletes any automated snapshots of the cluster. Also, when the retention period of the snapshot expires, Amazon Redshift automatically deletes it. If you want to keep an automated snapshot for a longer period, you can make a manual copy of the snapshot. Manual snapshots are retained until you delete them.

| Parameters: |
|---|
Creates an Amazon Redshift event notification subscription. This action requires an ARN (Amazon Resource Name) of an Amazon SNS topic created by either the Amazon Redshift console, the Amazon SNS console, or the Amazon SNS API. To obtain an ARN with Amazon SNS, you must create a topic in Amazon SNS and subscribe to the topic. The ARN is displayed in the SNS console.
You can specify the source type, and lists of Amazon Redshift source IDs, event categories, and event severities. Notifications will be sent for all events you want that match those criteria. For example, you can specify source type = cluster, source ID = my-cluster-1 and mycluster2, event categories = Availability, Backup, and severity = ERROR. The subscription will only send notifications for those ERROR events in the Availability and Backup categories for the specified clusters.
If you specify both the source type and source IDs, such as source type = cluster and source identifier = my-cluster-1, notifications will be sent for all the cluster events for my- cluster-1. If you specify a source type but do not specify a source identifier, you will receive notice of the events for the objects of that type in your AWS account. If you do not specify either the SourceType nor the SourceIdentifier, you will be notified of events generated from all Amazon Redshift sources belonging to your AWS account. You must specify a source type if you specify a source ID.
| Parameters: | subscription_name (string) – |
|---|
The name of the event subscription to be created.
Constraints:
| Parameters: |

Creates an HSM client certificate that an Amazon Redshift cluster will use to connect to the client’s HSM in order to store and retrieve the keys used to encrypt the cluster databases.
The command returns a public key, which you must store in the HSM. In addition to creating the HSM certificate, you must create an Amazon Redshift HSM configuration that provides a cluster the information needed to store and use encryption keys in the HSM. For more information, go to `Hardware Security Modules`_ in the Amazon Redshift Management Guide.
| Parameters: | hsm_client_certificate_identifier (string) – The identifier to be assigned to the new HSM client certificate that the cluster will use to connect to the HSM to use the database encryption keys. |

JBreadCrumb
and the BreadCrumbUI
present a series of JLabels
separated by Icons
.
The JBreadCrumb
itself is parameterized, so you can create a JBreadCrumb<File>
, JBreadCrumb<String>
, or whatever your heart desires. Each node/element is passed through a BreadCrumbFormatter
, which resembles:
public static interface BreadCrumbFormatter<T> { public void format(JBreadCrumbcontainer, JLabel label, T pathNode, int index); }
Someday I might change this so it relies on AbstractButtons
instead of JLabels
, but until I have a compelling use case the current implementation is sufficient. Using buttons would let me tap into more well-developed models for interacting with nodes, though. Currently you can add NavigationListeners
, which are a custom listener resembling:
public interface NavigationListener{ public enum ListSelectionType { SINGLE_CLICK, DOUBLE_CLICK, KEY }; public boolean elementsSelected(ListSelectionType type, T... elements); }
This is not currently designed to interact with AccessibleContexts
. So although the labels will be picked up naturally by any assistive technology, if you've added NavigationListeners
to interact with those labels those won't interface with assistive technology.
Between each label an icon is rendered, although this icon isn't attached to any JComponent
.
The other key ingredient that gives this component its mojo is the SplayedLayout
. In this case this acts like FlowLayout
, except it knows which components to squeeze when there isn't enough width to give everything it's preferred dimensions. That means if some labels are squished, you can mouse over each label to fully see it. (You can also see the SplayedLayout
at work in the BoxTabbedPaneUI.)
There's a lot of UX people waxing philosophical about bread crumbs in general. Here are a couple of articles that I found interesting:

ConocoPhillips seeking sales of Alaska assets
by The Associated PressANCHORAGE, ALASKA -- ConocoPhillips hopes to sell parts of its Alaska projects to offset risks and share the expenses of investments planned in the state, company officials said.
The sale package includes old, new and unbuilt projects representing most of Conoco's Alaska holdings, Alaska's Energy Desk reported Thursday.
The assets for sale include the Kuparuk River unit, the newer Alpine unit to the west and the undeveloped Willow project in the National Petroleum Reserve in Alaska, officials said.
The notable exception is the company's 36-per-cent share of the nation's largest oil field in Prudhoe Bay, officials said.
The proposed sales stem from a plan to invest US$11 billion on core assets in Alaska over the next decade, which does not include the estimated US$5 billion needed to bring the Willow project into production, ConocoPhillips spokeswoman Natalie Lowman said.
"We have a lot of exciting work that we are planning to do on the North Slope, and it costs a lot of money," Lowman said. "So what we're looking for is a co-venturer, a company that shares our vision for increasing production on the North Slope."
ConocoPhillips owns nearly all the assets up for sale, which the company said is unusual. Oil companies often split project ownership into chunks to help share costs, such as the Prudhoe Bay field in which BP and ExxonMobil Corp. also hold stakes, officials said.
The company does not wish to sell more than one-fourth of the assets, thereby retaining control, Lowman said.
The sale price will not be made public, Lowman said.
"This is a large commercial negotiation," Lowman said. "And I think those people who are interested will know how to find us."


Welcome
Starting PSQL
I had to jump through a few hidden hoops to get PSQL up
and running on my Ubuntu WSL. Most sources will insist that Postgres
is already installed on Ubuntu but this proved not to be the case for me.
Instead I got the most recent package (Version 13 as of writing):
apt-get install postgresql-13
Starting your Server
I had to start my server cluster??
sudo pg_ctlcluster 13 main start
You can check if your server is running with
service postgresql status
Opening PSQL
Setting up Postgresql will create a new 'postgres' user. Switch
to that user by running:
su postgres
Now you're operating as your 'postgres' user and can run postgres.
psql
If you have a database already set up you can open right to it:
psql my_database_name
Creating & Removing Databases
Create a database using 'createdb' and give it a name:
createdb new_database_name
To remove it you can use 'dropdb':
dropdb my_database_name
'Create' and 'Drop' are keywords to recognize throughout PSQL.
Creating & Removing Tables
Now that you have a database it's time to make some tables to store your data in.
Open it using:
\c my_database_name
Here's where we start getting into PSQL commands - as a best practice they're written all caps. You'll use 'CREATE TABLE' to make them, but you'll need to add parameters.
CREATE TABLE first_table (
End that first line with an open paranthesis - PSQL won't run anything until you end with a semicolon.
first_column text,
Columns are made up of two items: column name and data type.
second_column integer
Then close it out.
);
Just like databases, if you want to remove a table, you DROP it.
DROP TABLE first_table;
Adding Data to Your Tables
Now you can start adding your data! We'll go over the simple manual process.
'INSERT INTO' is our keyword for inserting data into a table.
INSERT INTO first_table VALUES ('Text goes here', 0);
The 'VALUES' keyword specifies what exactly we're inserting. You have to enter
exactly what the table is expecting, so in our case we need something for first_column that is text
and second_column that is an integer.
Updating Data
Sometimes you add columns after you've started to put data in. To update an existing table use ALTER TABLE.
To add a new column:
ALTER TABLE first_table ADD COLUMN name text;
To update an existing row for this new column, you'll have to be specific and tell PSQL exactly which row you want to change.
UPDATE first_table SET name = 'Okoye' WHERE second_value = 0;
Queries - How to see your data
You can run a Query on your table to see how your data is going in.
SELECT * FROM first_table;


Cranky Critic® Movie Reviews: That's The Way I Like It Rated [PG-13] , 95 minutes Starring Adrian Pang, Madeline Tan, Pierre Png and Anna Belle Francis Written and Directed by Glen Goie website: www.miramax.com
Try to imagine this: Bruce Lee as John Travolta in Saturday Night Fever. While you furrow your brow in consternation and confusion, Cranky'll describe That's The Way I Like It, which he adds to his list of required viewing for filmmaker wannabees. It's not that That's The Way I Like It is a drop everything must see flick. It's a perfectly average popcorn flick, set in Singapore during the rage of disco, back in 1977. Watching Caucasian culture/movie iconography dropped into a Chinese/Western mix yields a couple of belly laughs of recognition, one big surprise, and an attempt to toss the light comedy, "what is my place in all this?" kind of story with some fierce mob-style brutality. Luckily, the budget is so low, there are no big blood effects or shootings, just a beating or two. But I'm getting ahead of myself.
Ah Hock (Adrian Pang) is just an average guy in a low paying dead end job, stocking shelves in the local grocery store. He still lives with his parents, and they lavish praise on his med student younger brother Ah Beng, who has taken the "Western" name Leslie (Caleb Goh). For the twenty-something Hock, there isn't much to do in Singapore, other than hang out with his friends at the local bowling alley or movie house, where Bruce Lee flicks run almost continually. Hock is such a Lee devotee, that he can lip-synch and hip-synch (i.e. do the moves) of every movie.
One day though, Fists of Fury is no more at the local cinema, having been replaced by some disco monstrosity called Forever Fever, an obvious knock off of Saturday Night Fever, right down to the white suit, music and camera shots. As Fever's song hits "Staying Alive," "Jive Talking," "You Should Be Dancing" and "How Deep Is Your Love" pour off the screen, something in Hock is stirred. He wants to be the disco king. He wants the hair. He wants the clothes. He wants the moves. But, most important, he wants the $5000 cash prize being given away by the local discotheque to the best dance team in the land. The cash will more than pay for the brand spanking new Triumph motorcycle sitting in the dealer's window that he passes every day on his way to work.
And I betcha thought you had seen this before; that these internal revelations would turn Hock "gay". Nope. Sorry.
Guided by his Guardian Angel (Dominic Pace as the John Travolta clone who steps out of the screen to advise Hock) he enlists gal pal Mei (Madeline Tan) to secretly take lessons with him. Mei is greatly attracted to Hock, though he's ignorant of it and has his eye on fellow student Julie (Anna Belle Francis). Julie's partner, Richard (Pierre Png) is ego-personified, totally jealous and not above having his rival beaten to a bloody pulp. There you have it, folks, enough story to fill any movie. Friendships are strained. Rivalries explode, both on the dance floor and in violence, and local family values are severely tested (which is the surprise in the film that I wrote about above, but will not spill).
Last year, Cranky blasted the disco flicks 54 and Last Days of Disco for not spending the bucks on rights to the songs that best exemplified the era. So, how does That's The Way I Like It manage all them Bee Gees tunes, plus the title, and other disco staples such as "Instant Replay," "Rock The Boat" and non-disco smash "Kung-Fu Fighting"? They bought the rights and produced imitations of the original hits. Just like K-Tel did with their record collections back in the 70s, or teevee producers like Glen Larson did on their shows in the 80s. It's just another lesson on how low budget productions can get by. For those of you who aren't filmmaker wannabees, the copies aren't so close to the bone that you can't tell the difference, but the songs are strong enough that you won't care.
On average, a first run movie ticket will run you Eight Bucks. Were Cranky able to set his own price to That's The Way I Like It, he would have paid...
$3.00
In one word, it's "cute". A perfectly adequate rental. Had we seen anything like this before now, the rating would've been much lower. Than again, watching Bruce Lee moves in a Travolta white suit is worth the price of the rental.

--- layout: post title: "Payment types catamorphism" description: "You can find the catamorphism for a custom sum type. Here's an example." date: 2019-07-08 6:08 UTC tags: [Software Design, Haskell] --- {% include JB/setup %}
{{ page.description }}
This article is part of an article series about catamorphisms. A catamorphism is a universal abstraction that describes how to digest a data structure into a potentially more compact value.
This article presents the catamorphism for a domain-specific sum type, as well as how to identify it. The beginning of this article presents the catamorphism in C#, with a few examples. The rest of the article describes how to deduce the catamorphism. This part of the article presents my work in Haskell. Readers not comfortable with Haskell can just read the first part, and consider the rest of the article as an optional appendix.
In all previous articles in the series, you've seen catamorphisms for well-known data structures: Boolean values, Peano numbers, Maybe, trees, and so on. These are all general-purpose data structures, so you might be left with the impression that catamorphisms are only related to such general types. That's not the case. The point of this article is to demonstrate that you can find the catamorphism for your own custom, domain-specific sum type as well.
The custom type we'll examine in this article is the Church-encoded payment types I've previously written about. It's just an example of a custom data type, but it serves the purpose of illustration because I've already shown it as a Church encoding in C#, as a Visitor in C#, and as a discriminated union in F#.
The catamorphism for the IPaymentType
interface is the Match
method:
T Match<T>( Func<PaymentService, T> individual, Func<PaymentService, T> parent, Func<ChildPaymentService, T> child);
As has turned out to be a common trait, the catamorphism is identical to the Church encoding.
I'm not going to show more than a few examples of using the Match
method, because you can find other examples in the previous articles,
> IPaymentType p = new Individual(new PaymentService("Visa", "Pay")); > p.Match(ps => ps.Name, ps => ps.Name, cps => cps.PaymentService.Name) "Visa" > IPaymentType p = new Parent(new PaymentService("Visa", "Pay")); > p.Match(ps => ps.Name, ps => ps.Name, cps => cps.PaymentService.Name) "Visa" > IPaymentType p = new Child(new ChildPaymentService("1234", new PaymentService("Visa", "Pay"))); > p.Match(ps => ps.Name, ps => ps.Name, cps => cps.PaymentService.Name) "Visa"
These three examples from a C# Interactive session demonstrate that no matter which payment method you use, you can use the same Match
method call to extract the payment name from the p
object.
As in the previous article, I'll use Fix
and cata
as explained in Bartosz Milewski's excellent article on F-Algebras.
First, you'll have to define the auxiliary types involved in this API:
data PaymentService = PaymentService { paymentServiceName :: String , paymentServiceAction :: String } deriving (Show, Eq, Read) data ChildPaymentService = ChildPaymentService { originalTransactionKey :: String , parentPaymentService :: PaymentService } deriving (Show, Eq, Read)
While F-Algebras and fixed points are mostly used for recursive data structures, you can also define an F-Algebra for a non-recursive data structure. You already saw examples of that in the articles about Boolean catamorphism, Maybe catamorphism, and Either catamorphism. While each of the three payment types have associated data, none of it is parametrically polymorphic, so a single type argument for the carrier type suffices:
data PaymentTypeF c = IndividualF PaymentService | ParentF PaymentService | ChildF ChildPaymentService deriving (Show, Eq, Read) instance Functor PaymentTypeF where fmap _ (IndividualF ps) = IndividualF ps fmap _ (ParentF ps) = ParentF ps fmap _ (ChildF cps) = ChildF cps
I chose to call the carrier type c
(for carrier). As was also the case with BoolF
, MaybeF
, and EitherF
, the Functor
instance ignores the map function because the carrier type is missing from all three cases. Like the Functor
instances for BoolF
, MaybeF
, and EitherF
, it'd seem that nothing happens, but at the type level, this is still a translation from PaymentTypeF c
to PaymentTypeF c1
. Not much of a function, perhaps, but definitely an endofunctor.
 IndividualF parentF :: PaymentService -> Fix PaymentTypeF parentF = Fix . ParentF childF :: ChildPaymentService -> Fix PaymentTypeF childF = Fix . ChildF
That's all you need to identify the catamorphism.
At this point, you have two out of three elements of an F-Algebra. You have an endofunctor (PaymentTypeF
), and an object c
, but you still need to find a morphism PaymentTypeF c -> c
.
As in the previous articles, start by writing a function that will become the catamorphism, based on cata
:
paymentF = cata alg where alg (IndividualF ps) = undefined alg (ParentF ps) = undefined alg (ChildF cps) = undefined
While this compiles, with its undefined
implementations, it obviously doesn't do anything useful. I find, however, that it helps me think. How can you return a value of the type c
from the IndividualF
case? You could pass an argument to the paymentF
function, but you shouldn't ignore the data ps
contained in the case, so it has to be a function:
paymentF fi = cata alg where alg (IndividualF ps) = fi ps alg (ParentF ps) = undefined alg (ChildF cps) = undefined
I chose to call the argument fi
, for function, individual. You can pass a similar argument to deal with the ParentF
case:
paymentF fi fp = cata alg where alg (IndividualF ps) = fi ps alg (ParentF ps) = fp ps alg (ChildF cps) = undefined
And of course with the remaining ChildF
case as well:
paymentF :: (PaymentService -> c) -> (PaymentService -> c) -> (ChildPaymentService -> c) -> Fix PaymentTypeF -> c paymentF fi fp fc = cata alg where alg (IndividualF ps) = fi ps alg (ParentF ps) = fp ps alg (ChildF cps) = fc cps
This works. Since cata
has the type Functor f => (f a -> a) -> Fix f -> a
, that means that alg
has the type f a -> a
. In the case of PaymentTypeF
, the compiler infers that the alg
function has the type PaymentTypeF c -> c
, which is just what you need!
You can now see what the carrier type c
is for. It's the type that the algebra extracts, and thus the type that the catamorphism returns.
This, then, is the catamorphism for the payment types. Except for the tree catamorphism, all catamorphisms so far have been pairs, but this one is a triplet of functions. This is because the sum type has three cases instead of two.
As you've seen repeatedly, this isn't the only possible catamorphism, since you can, for example, trivially reorder the arguments to paymentF
. The version shown here is, however, equivalent to the above C# Match
method.
You can use the catamorphism as a basis for other functionality. If, for example, you want to convert a Fix PaymentTypeF
value to JSON, you can first define an Aeson record type for that purpose:
data PaymentJson = PaymentJson { name :: String , action :: String , startRecurrent :: Bool , transactionKey :: Maybe String } deriving (Show, Eq, Generic) instance ToJSON PaymentJson
Subsequently, you can use paymentF
to implement a conversion from Fix PaymentTypeF
to PaymentJson
, as in the previous articles:
toJson :: Fix PaymentTypeF -> PaymentJson toJson = paymentF (\(PaymentService n a) -> PaymentJson n a False Nothing) (\(PaymentService n a) -> PaymentJson n a True Nothing) (\(ChildPaymentService k (PaymentService n a)) -> PaymentJson n a False $ Just k)
Testing it in GHCi, it works as it's supposed to:
Prelude Data.Aeson B Payment> B.putStrLn $ encode $ toJson $ parentF $ PaymentService "Visa" "Pay" {"transactionKey":null,"startRecurrent":true,"action":"Pay","name":"Visa"}
Clearly, it would have been easier to define the payment types shown here as a regular Haskell sum type and just use standard pattern matching, but the purpose of this article isn't to present useful code; the only purpose of the code here is to demonstrate how to identify the catamorphism for a custom domain-specific sum type.
Even custom, domain-specific sum types have catamorphisms. This article presented the catamorphism for a custom payment sum type. Because this particular sum type has three cases, the catamorphism is a triplet, instead of a pair, which has otherwise been the most common shape of catamorphisms in previous articles.


S&P upgrades Kyiv to 'B' on expected debt reduction
The outlook is stable.
S&P Global Ratings on November 15, 2019, raised its long-term issuer credit rating on the Ukrainian City of Kyiv to 'B' from 'B-.'
"We anticipate that Ukraine's capital city of Kyiv will completely offset its intergovernmental debt with the Ministry of Finance once its infrastructure projects are completed in 2020. This would reduce the city's direct debt by 50% by 2021," the rating agency said in a statement.
"We believe that uncertainties regarding the potential dismissal of the mayor as the head of the city's state administration and the date of the next municipal election in 2020 will not affect the city's ability to honor its debt obligations," S&P experts said.
The outlook on Kyiv is stable.
"The stable outlook reflects our expectations that Kyiv will preserve its sound operating surpluses, supported by the solid economic recovery. The outlook also factors in our assumption that the city will borrow moderately in the medium term," the rating agency said.

1. The prelimary study of Cloud Top Height (CTH) has shown that the altitude of an object can be derived from successive airborne images using stereographic reconstruction.
2. The bias study and error analysis will be performed through the comparison between the estimated CTH and the direct measurements of CTH from other airborne instruments.
3. Object detection and object tracking algorithms, e.g., Principal Component Analysis (PCA), will be applied to automatically identify and track objects from successive images.
