NodeSprites are typically managed by a Data
object.
NodeSprites can separately maintain adjacency lists for both a general graph structure (managing lists for inlinks and outlinks) and a tree structure (managing a list for child links and a parent pointer). The graph and tree lists are maintained completely separately to maximize flexibility. While the the tree lists are often used to record a spanning tree of the general network structure, they can also be used to represent a hierarchy completely distinct from a co-existing graph structure. Take this into account when iterating over the edges incident on this node.

Exporting CloudEvents
CloudEvents is a specification for describing event data in a common way. Its aim is to provide interoperability across services, platforms and systems. Debezium enables you to configure a MongoDB, MySQL, PostgreSQL, or SQL Server connector to emit change event records that conform to the CloudEvents specification.
|
Support for CloudEvents is in an incubating state. This means that exact semantics, configuration options, and other details may change in future revisions based on feedback. Please let us know your specific requirements or if you encounter any problems while using this feature. |
The CloudEvents specification defines:
-
A set of standardized event attributes
-
Rules for defining custom attributes
-
Encoding rules for mapping event formats to serialized representations such as JSON or Avro
-
Protocol bindings for transport layers such as Apache Kafka, HTTP or AMQP
To configure a Debezium connector to emit change event records that conform to the CloudEvents specification, Debezium provides the io.debezium.converters.CloudEventsConverter
, which is a Kafka Connect message converter.
Currently, only structured mapping mode is supported. The CloudEvents change event envelope can be JSON or Avro and each envelope type supports JSON or Avro as the data
format. It is expected that a future Debezium release will support binary mapping mode.
For information about using Avro, see:
Example event format
The following example shows what a CloudEvents change event record emitted by a PostgreSQL connector looks like. In this example, the PostgreSQL connector is configured to use JSON as the CloudEvents format envelope and also as the data
format.

}
| 1 | Unique ID that the connector generates for the change event based on the change event’s content. |
| 2 | The source of the event, which is the logical name of the database as specified by the database.server.name property in the connector’s configuration. |
| 3 | The CloudEvents specification version. |
| 4 | Connector type that generated the change event. The format of this field is io.debezium.CONNECTOR_TYPE.datachangeevent . The value of CONNECTOR_TYPE is mongodb , mysql , postgresql , or sqlserver . |
| 5 | Time of the change in the source database. |
| 6 | Describes the content type of the data attribute, which is JSON in this example.
The only alternative is Avro. |
| 7 | An operation identifier. Possible values are r for read, c for create, u for update, or d for delete. |
| 8 | All source attributes that are known from Debezium change events are mapped to CloudEvents extension attributes by using the iodebezium prefix for the attribute name. |
| 9 | When enabled in the connector, each transaction attribute that is known from Debezium change events is mapped to a CloudEvents extension attribute by using the iodebeziumtx prefix for the attribute name. |
| 10 | The actual data change itself. Depending on the operation and the connector, the data might contain before , after and/or patch fields. |
The following example also shows what a CloudEvents change event record emitted by a PostgreSQL connector looks like. In this example, the PostgreSQL connector is again configured to use JSON as the CloudEvents format envelope, but this time the connector is configured to use Avro for the data
format.

| 1 | Indicates that the data attribute contains Avro binary data. |
| 2 | URI of the schema to which the Avro data adheres. |
| 3 | The data attribute contains base64-encoded Avro binary data. |
It is also possible to use Avro for the envelope as well as the data
attribute.
Example configuration
Configure io.debezium.converters.CloudEventsConverter
in your Debezium connector configuration. Following is an example of configuring CloudEventsConverter
to emit change event records that:
-
Use JSON as the envelope
-
Use the schema registry at
http://my-registry/schemas/ids/1
to serialize thedata
attribute as binary Avro data
In this example, you could omit the specification of serializer.type
because json
is the default.

...
CloudEventsConverter
converts Kafka record values. In the same connector configuration, you can specify key.converter
if you want to operate on record keys, for example you might specify StringConverter
, LongConverter
, JsonConverter
, or AvroConverter
.
Configuration properties
When you configure a Debezium connector to use the CloudEvent converter you can specify the following properties.

CAMPCO releases spicy toffee in the market
by Special CorrespondentThe Central Arecanut and Cocoa Marketing and Processing Cooperative Ltd (CAMPCO) released its first spicy toffee in the market on Wednesday.
Speaking during its launch, M. Suresh Bhandary, Managing Director of the cooperative said the new product has been prepared from sugar-based syrups and natural black pepper powder and ginger extracts.
The cooperative has now produced 12 tonnes of spicy toffee. Its production will be increased depending on market demand, he said.
Mr. Bhandary said in olden days, some people traditionally made the toffee using black pepper, ginger and jaggery at homes. The CAMPCO has borrowed the same concept in making its new product using sugar-based syrups.
At the same time, it is doing research and development on replacing sugar-based syrups with jaggery for mass production of its spicy toffee.
The R&D is expected to be over in another three months. Once the jaggery-based formula is ready, the cooperative will use the same to have the traditional flavour.
Mr. Bhandary said CAMPCO is the first to make and market the spicy toffee in the organised sector.
The Managing Director claimed that the spicy toffee acted as a body-cooling agent and a mouth fresher. It also decreased the feeling of thirst.
Each spicy toffee weighs 3.6 gm and is priced at ₹1. The cooperative supplies them to the dealers in jars. Each jar will have 250 pieces.
The president of the cooperative S.R. Satishchandra also launched the first television commercial of the cooperative to market its various chocolate products across the country.
The commercial has been made in Kannada, English, Hindi, Telugu, Bengali and Tamil to reach out to various segments of customers. The commercial is of 60-seconds duration.


Tommy Wright looking forward to run of games
Tommy Wright is looking forward to a run of games after a disrupted Ladbrokes Premiership season so far for
St Johnstone.
The Perth side went into the most recent international break two points ahead of bottom team St Mirren following the 4-1 defeat at home to Hibernian.
Wright welcomes Aberdeen to McDiarmid Park on Saturday, followed by a trip to Motherwell next weekend before a game at Rugby Park against Kilmarnock the following Wednesday night, as he hopes to get some momentum going.
The Perth club's boss said: "We planned for the international break, we knew it was coming.
"But where our season has been disjointed, we lost a game because of the League Cup semi-final and we will lose another game because of the final because we were meant to play Celtic that weekend.
"It feels as though your season hasn't really got started.
"The last three or four seasons, until the League Cup is out the way, we have had a bit more disruption to our season, because we have been playing teams involved in the semi-finals or final.
"It is hard to believe we are coming towards the end of November and we have only played 12 league games but we have three games in 10 days – and then we don't have a game.
"Hopefully we can get a bit of momentum with it (three games). That will be the aim.
"Every game in the league is tough. Even in our situation I believe we can take points off any team in the league so starting with Aberdeen on Sunday, we have to get a win and then go to Motherwell.
"But players enjoy playing games and it will be nice to get three games in 10 days."
Wright anticipates another tough game against Derek McInnes' side, with whom they drew 1-1 at Pittodrie earlier in the season.
The Northern Irishman said: "We have had many battles with them down the years and we look forward to it.
"Derek is getting most of his players back and Scott McKenna coming back gives them a lot of strength at the back.
"They have quietly moved into third place in the league whereas a few weeks ago everyone was writing them off."

Developing our first SOPs
Mar 2, 2018 • Team
Hello! My name is Ashley, and I am a 19 year old student at the University of Nebraska. My first experience with virtual reality (VR) was definitely very different from what I expected. I thought that it would be just like playing video games while holding the screen very close to your face. I was not expecting to be immersed into the world of a video game. I was very pleasantly surprised, and within the context of my job, I was immediately thinking of how I would have responded to this as a ten year old kid. It would have been quite the experience.
Currently, I’m working on standard operating procedures (SOP’s) in order to introduce high school kids to virtual reality, and all the possibilities that come with it. It was my first experience writing an SOP and working with VR, so everything was a little green for me. We were specifically writing about medium, in which you can draw/sculpt/create in 3D. I personally thought the writing of it was generally easy; the whole project turned into more of “what would be most beneficial to know for a person who has never done VR before?”. So we wrote about everything we came across- the general stuff on the headset and controllers to links to videos that explain how to use the most basic tools within medium.
I think the final SOP was great in a word document, but not so great in practice. Somewhere along the way we had forgotten who we were writing this for- high school students.  When they came in to test everything, they spent their time better by just playing with the game then they did watching all of the instructional videos we had found. I think our original SOP would be great for those who haven’t had much contact with this type of technology before; with the kids it was easier to give them some form of direction, and then just let them figure it out.
Currently, I have just finished writing an SOP for a similar program called MasterpieceVR, which is also a creative type of game. Within this, I used the short tutorial built within the program, that just gave a basic rundown of the program, and left it at that. I think this was a good decision considering the inefficiency of writing lots of instructions for something that is easier to learn by doing.
Currently, my coworkers (Matt and Matt) are working on doing Minecraft in VR. As they were surprised to hear, I have never played minecraft before. Therefore, I am the designated ‘guinea pig’ for their SOP once it is finished. We assume most kids will have some experience with this game, because it is so popular, but in order to efficiently instruct people who have no experience (like me) they need a pair of fresh eyes to see what needs to be explained. Unfortunately, that means I am kept in the dark until the first exposure. From what I understand, the idea behind using minecraft is so that we can create a space where kids from all over the world can log onto the same server to create real life structures, like buildings and cities, which is super awesome. It sounds like they’re having some difficulties with the servers, and with some of the technology our college uses.
I think the entirety of this experience so far has just really opened my eyes to the opportunities within VR- not just for education, but everything. You could have meetings from all across the world, or create a to-scale solution to real word problems, all within VR. I think the work that we are doing is just the tip of the iceberg.

🔮 Problem Solving 🔮
Simple Problem
Whilst applying CSS(Styling) to my blog website, I couldn't seem to get a picture to resize no matter what I tried doing. I had applied a selector(id) to the picture so I could apply some settings to it, but the settings would not apply.
I re-read through the CSS several times, I googled for solutions, I used the dev tools in the browser to see what settings were being applied to the picture but was still left confused as to why my settings were not being applied correctly.
I was having a feeling of frustration as I knew the answer should be very obvious, and it was. Once I uncovered the mistake I was able to quickly fix it, it was a simple syntax error (ID selectors in CSS need to be pre-cursored with a '#' as opposed to a '.' for class selectors)
I learned that paying attention to finer details whilst coding will save time up front, I also reminded myself of the importance of applying Occam's Razor ( Start with the most simple and obvious) when seeking a solution.
Elegant Solution
I wouldn't be able to draw upon any elegant solutions that I have come up with so far at Dev Academy. One from my career was a solution I came up with to help standardize a process that was time-consuming and inconsistent.
My team was tasked with performing technical and customer health checks on a nightly basis for one of our customers who were having repeat issues with their call center solutions, the team was having to manually call 5 separate parties to ask the same question, then format and send out an email to all stakeholders advising of the results.
I looked at the process and used my understanding to identify some efficiencies that could be driven, I brainstormed some possible solutions and then went away to test which ones would work. I spoke with the customers and organized a repeat conference call which would occur at the same time each night, this meant that our staff only had to dial in once and wait for the call centers around the country to dial in with their health check. I also implemented an automated form that the team could complete at the end of the conference, this would automatically generate an email out to relevant stakeholders advising of the health check results.
I felt buoyant knowing that I could empower my staff to carry out a drawn-out process in a much shorter space of time and with greater accuracy. I learned that often the solution to an issue may not be complex, but it requires someone to simply take the time to assess the current state to see if efficiency can be driven.
Problem Solving Methods
The methods I have used most frequently so far at Dev Acadamey are in order as follows:
- Trial & Error
- Reading Errors
- Console Logging
- Pseudocode
- Reflection
Upon reflection, I need to start reaching out for more help from peers when I get stuck.

Frenchman dies in Bali’s Tabanan regency after getting swept out to sea
by Coconuts BaliA 75-year-old Frenchman who went missing while swimming in Bali’s Pasut Beach, Tabanan regency yesterday afternoon has been declared dead, the province’s Search and Rescue Agency (Basarnas Bali) said, after his body was finally found just before midnight.
The victim, identified as Gilbert Henry Marcel Guidot, was found about a kilometer away from where he was last seen, according to a statement issued by Basarnas Bali.
“The integrated Search and Rescue team conducted a search all night along the beach, and at 11:45pm the body was found face down,” said acting head of Basarnas Bali I Made Junetra, as quoted in the statement.
Authorities said they received a report of the missing foreigner yesterday afternoon, and six personnel were then sent to the location. It took authorities about two hours to reach Pasut Beach, which was followed by a land search. There was no search using a rubber boat due to limited visibility in the evening hours, they said.
According to the statement, Guidot’s body has been taken to Tabanan General Hospital.

Disease Outbreak Reported
The emergence of meningococcal
serogroup W135 in Burkina Faso has major implications for public health in the African
continent. A research agenda has been agreed by Le Comité National de Pilotage pour la
Méningite (Crisis Committee) established by
the Ministry of Health in Burkina Faso and supported in its
implementation by a research team consisting of WHO, Epicentre, WHO Collaborating
Centre for Reference and Research on Meningococci, Oslo, Norway,
Centers for Disease Control and Prevention (CDC, Atlanta, United States ) and l'Association pour la Médecine préventive (AMP). The topics include: a detailed description and evaluation of the risk factors of
the current epidemic; an ecological analysis of association between vaccine coverage and
epidemics; N. meningitidis seroprevalence and carriage; and
the socioeconomic impact of the epidemic. The team
is assessing the feasibility of estimating immunogenicity and efficacy of
tetravalent vaccine. Niger: As
of 21 April 3 518 cases including 308 deaths (case-fatality ratio 8.8%) have been reported
to WHO. The district
of Matameye (Zinder) is still particularly affected. La Direction Régionale de la
Santé Publique et de la Lutte contre les Endémies of Maradi is investigating the
situation in the districts of Dakaro and Guidan-Roumdji where cases are still being
reported by the local health teams.
Burkina
Faso: As of 28 April 11 899 cases including 1 368 deaths (case-fatality ratio
11.5%) have been reported to WHO.
During the week of 22 April - 28 April, the number of cases reported, 652 cases
and 67 deaths with a weekly case-fatality rate of 10.5%, indicate a downward trend in
the epidemic .

class: center, middle # .center[SoftLayer API] ### .center[Object Masks] Christopher Gallo, Senior API Developer --- # Object Masks > An array like string used to select properties to be included in the response to an API request ```python *mask[ # Required start of the mask property1[ nested1, # property1->nested1 nested2[ # property1->nested2 reallyNested # property1->nested2->reallyNested ] ], property2, property3 *] # Required end of the mask ``` When sending into the API, it will look something like this: ```bash "mask[property1[nested1,nested2[reallyNested]],property2,property3]" ``` --- # Concepts ### Datatype Represent a table in a SQL database, generally speaking. The starting datatype for an objectMask is the return Type of a method ### Local Property The columns in the table that the datatype represents. Adding a local property to an objectMask removes any default properties from the returned data. ### Relational Property Properties in foreign tables that relate to this peice of data. Adding relational properties to an objectMask esentially adds another `SQL JOIN` clause to the select statement being executed. --- # Concepts ObjectMasks control which properties are added to the SQL `SELECT` and `JOIN` clauses. ```bash $ slcli --format=json call-api SoftLayer_Account getObject \ --mask="mask[id,companyName,virtualGuests[id,hostname]]" ``` Would generate a SQL statement something like ```sql SELECT account.id, account.companyName, virtual_guest.id, virtual_guest.hostname FROM account JOIN virtual_guest ON virtual_guest.account_id = account.id WHERE account.id = active_user.account_id ``` --- # Step 1: Find The Datastructure .center[
] Only methods that mention they accept ObjectMask headers can have masks applied to them --- # Step 2: Find Properties .columnA[
] .columnB[ ```python mask[id, hostname, createDate, allowedNetworkStorage] ``` All these properties are on the same 'level' as the Virtual_Guest datatype. `allowedNetworkStorage` is a datatype itself, so we can expand into that datatype and select more properties. ] --- # Output ```bash $ slcli --format=json call-api SoftLayer_Virtual_Guest getObject --id=113821290 \ --mask="mask[id,hostname,allowedNetworkStorage]" ``` ```json { "hostname": "testname", "id": 113821290, "allowedNetworkStorage": [ { "accountId": 307608, "capacityGb": 40, "createDate": "2020-04-16T15:25:47-06:00", "guestId": null, "hardwareId": null, "hostId": null, "id": 135925188, "nasType": "ISCSI", "serviceProviderId": 1, "serviceResourceName": "Storage Type 02 Block Aggregate stbf-dal1303h", "storageTypeId": "5", "upgradableFlag": true, "username": "SL02SL307608-30" } ] } ``` --- # Step 3: Find More Properties .columnA[
] .columnB[ ```python mask[id, hostname, createDate, allowedNetworkStorage[ id, capacityGb, billingItem ] ] ``` .lightPurple[allowedNetworkStorage] Is a Network_Storage Datatype, so we can open up some .lightPurple[[]] at the end of that property and go deeper into the relationships to select more properties. When sending in the objectMask to the API, its best to remove spaces and newlines, they are added here for readability. ] --- ```bash $ slcli --format=json call-api SoftLayer_Virtual_Guest getObject --id=113821290 --mask="mask[id,hostname,allowedNetworkStorage[id,capacityGb,billingItem]]" ``` ```json { "hostname": "testname", "id": 113821290, "allowedNetworkStorage": [ { "billingItem": { "categoryCode": "storage_as_a_service", "createDate": "2020-04-16T15:24:15-06:00", "currentHourlyCharge": "0", "cycleStartDate": "2022-06-03T23:10:08-06:00", "description": "Storage as a Service", "hourlyRecurringFee": "0", "hoursUsed": "455", "id": 652744096, "laborFee": "0", "laborFeeTaxRate": "0", "lastBillDate": "2022-06-03T23:10:08-06:00", "modifyDate": "2022-06-03T23:10:08-06:00", "nextBillDate": "2022-07-03T23:00:00-06:00", "recurringFeeTaxRate": "0", "recurringMonths": 1, "serviceProviderId": 1, "setupFee": "0", "setupFeeTaxRate": "0" }, "capacityGb": 40, "id": 135925188 } ] } ``` --- # Step 4: Even More Properties .columnA[
] .columnB[ ```python mask[id, hostname, createDate, allowedNetworkStorage[ id, capacityGb, billingItem[ id, hoursUsed, notes ] ] ] ``` .lightPurple[billingItem] Is a Billing_Item Datatype, so we can open up some .lightPurple[[]] at the end of that property and go deeper into the relationships to select more properties. Multiple properties can be opened up this way in a single mask. ] --- ```bash $ slcli --format=json call-api SoftLayer_Virtual_Guest getObject --id=113821290 --mask="mask[id,hostname,allowedNetworkStorage[id,capacityGb,billingItem[id,hoursUsed,notes]]]" ``` ```json { "hostname": "testname", "id": 113821290, "allowedNetworkStorage": [ { "billingItem": { "hoursUsed": "455", "id": 652744096, "notes": "SL02SL307608-30" }, "capacityGb": 40, "id": 135925188 } ] } ``` Since we selected some local (to Billing_Item) properties, this reduced the amount of data returned compared to the previous API call. --- # XML Example ```xml
getObject
*
headers
authenticate
username
SL123456
apiKey
APIKEYGOESHERE
*
SoftLayer_ObjectMask
*
mask
*
mask[id,companyName]
``` --- # SOAP Example ```xml
*
SL12345
APIKEY
*
*
mask[id,companyName]
``` You can use .lightPurple[ns1:< SERVICE >ObjectMask] style object masks as well, which is a < SERVICE > style object and the objects defined there are included in the mask. However it is often simpler to just use the .lightPurple[mask[]] string format. --- # Warnings The ObjectMask system is very powerful, but it does allow you to shoot yourself in the foot if you are not careful. For example, most Datatypes link back to the Account Datatype, which allows you to branch off to all sorts of unrelated data. `"mask[id,hostname,account[invoices]]"` ```bash curl -g -v -u $SL_USER:$SL_APIKEY 'https://api.softlayer.com/rest/v3.1/SoftLayer_Virtual_Guest/113821290/ getObject.json?objectMask=mask[id,hostname,account[invoices]]' > out.json < HTTP/1.1 200 OK < Date: Thu, 23 Jun 2022 03:48:38 GMT < Server: Apache < X-Frame-Options: SAMEORIGIN *< Content-Length: 5098863 (5.1Mb) Without the `invoices` property the response is only 5035 bytes < Vary: Accept-Encoding < Connection: close < Content-Type: application/json < Strict-Transport-Security: max-age=31536000 ``` As a rule, try to limit your mask to only the properties you need. --- Getting too many objects can also be a problem and result in Internal Server Errors.  Which has many of the same properties, but some that do not appear in the parent class. For example, VMWare servers provisioned by IBM Cloud have some basic data about them and their virtual guests available through the API. The .lightPurple[virtualGuests] property exists on the SoftLayer_Hardware_Server class, but not on the SoftLayer_Hardware class. ```bash $> slcli call-api SoftLayer_Account getHardware --mask="mask[id, hostname, virtualGuests[id]]" SoftLayerAPIError(500): Property 'virtualGuests' not valid for 'SoftLayer_Hardware'. ``` --- # Type Casting Object Masks Forcing the API to use the SoftLayer_Hardware_Server datatype helps solve this problem. ```bash $ ./slcli --format=json call-api SoftLayer_Account getHardware * --mask="mask(SoftLayer_Hardware_Server)[id, hostname, virtualGuests[id]]" ``` ```json [ { "hostname": "bardcabero", "id": 1403539, "virtualGuests": [] }, { "hostname": "gpu.vmware", "id": 1866407, "virtualGuests": [ { "id": 99423014 }, { "id": 113102210 } ] } ] ``` --- # Type Casting Object Masks This is also useful for the SoftLayer_Search service, or any of the few services that can return multiple datatypes (Billing_Item is the biggest other example). .lightPurple[SoftLayer_Search::search()] returns the SoftLayer_Entity datatype, which doesn't really have any properties at all, so by default its impossible to apply a mask to them. If I wanted to find all the Servers and Virtual Guests with test.com in their FQDN, I would do something like this. ```bash $ ./slcli --format=json call-api SoftLayer_Search search "_objectType:SoftLayer_Hardware,SoftLayer_Virtual_Guest test.com" ``` --- ```json [ {"matchedTerms": [ {"value": "domain:|test.com|"}, {"value": "domain.sort:|test.com|"} ], "relevanceScore": "9.017289", "resource": { "accountId": 307608, "createDate": "2022-02-08T08:33:12-06:00", "dedicatedAccountHostOnlyFlag": false, "deviceStatusId": 8, "domain": "test.com", "fullyQualifiedDomainName": "lab-web.test.com", "hostname": "lab-web", }, "resourceType": "SoftLayer_Virtual_Guest" }, {"matchedTerms": [ {"value": "domain:|test.com|"}, {"value": "domain.sort:|test.com|"} ], "relevanceScore": "9.017289", "resource": { "accountId": 307608, "createDate": "2022-04-22T09:03:42-06:00", "dedicatedAccountHostOnlyFlag": false, "deviceStatusId": 8, "domain": "test.com", "fullyQualifiedDomainName": "testvs-9dca.test.com", "hostname": "testvs-9dca", }, "resourceType": "SoftLayer_Virtual_Guest" }, ``` --- # Type Casting Object Masks But if I want to use an objectMask I get the following error. ```bash $ ./slcli --format=json call-api SoftLayer_Search search "_objectType:SoftLayer_Hardware,SoftLayer_Virtual_Guest test.com" --mask="mask[id,hostname]" SoftLayerAPIError(500): Property 'id' not valid for 'SoftLayer_Container_Search_Result'. ``` Solution: ```bash slcli --format=json call-api SoftLayer_Search search "_objectType:SoftLayer_Hardware,SoftLayer_Virtual_Guest test.com" --mask="mask[ resource(SoftLayer_Hardware)[id, hostname], resource(SoftLayer_Virtual_Guest)[id, hostname] ]" ``` --- ```json [ { "matchedTerms": [ {"value": "domain:|test.com|"}, {"value": "domain.sort:|test.com|"} ], "relevanceScore": "9.017654", "resource": { "hostname": "lab-web", "id": 127890106 }, "resourceType": "SoftLayer_Virtual_Guest" }, { "matchedTerms": [ {"value": "domain:|test.com|"}, {"value": "domain.sort:|test.com|"} ], "relevanceScore": "9.017654", "resource": { "hostname": "testvs-9dca", "id": 129906358 }, "resourceType": "SoftLayer_Virtual_Guest" } ] ``` --- # Conclusion ObjectMasks are what makes the SoftLayer API so versitile, but can be very confusing. The API is basically a huge [ORM Model](http://www.orm.net), and the datatypes are all of those models you have access to. The objectMasks are how you select which of those models you want to query and be returned.

We all love coffee. It's an experience, from the aroma of the beans to the rich, warm color shining through the package. We'd like you to join us in intensifying that experience. And for really cheap, honestly.
Groves Coffee is co-owned by Mark Turansky and Mike Claypoole, neighbors in The Groves of Mount Pleasant, SC. Yes, that's the origin of our name. Coffee is grown in a grove, too. A grove is a shady natural place that has positive feelings, just like our neighborhood, so it works for us.
Mark asked Mike "Do you drink coffee?" soon after Mike moved in. A couple of hours later, Mark handed Mike a Ziploc stuffed with fresh roasted coffee. The beans were still warm. The smell was incredible. Mike's been drinking coffee since he was 16, so about 25 years, give or take. Receiving a fresh roast changes your coffee experience, no matter how many years you've been drinking it. We believe it's the single most important factor to a good cup of coffee.
We hope you join us on this journey. Fresh roasted coffee is amazing and we'd love to roast some for you. We only roast small batches, so we can customize each roast to your feedback.

Cython is essentially a Python to C translator. Cython allows you to use syntax similar to Python, while achieving speeds near that of C.
This post describes how to use Cython to speed up a single Python function involving ‘tight loops’. I’ll leave more complicated applications - with many functions and classes - for a later post.
Should I use Cython?
If you’re using Python and need performance there are a variety of options, see quantecon for a detailed comparison. And of course you could always choose a different language like Julia, or be brave and learn C itself.
While the static compilation approach of Cython may not be cutting edge, Cython is mature, well documented and capable of handling large complicated projects. Cython code lies behind many of the big Python scientific libraries including scikit-learn
and pandas
.
The example
Our example function evaluates a Radial Basis Function (RBF) approximation scheme. We assume each data point is a ‘center’ and use Gaussian type RBFs
so our function takes an input data array \( X\) of shape (N, D), a parameter array \( \beta\) of length N and a ‘bandwidth’ parameter \(\theta\) and return an array of fitted values \( \hat Y \) of length N.
Python loops
Here’s the naive Python implementation
from math import exp
import numpy as np
def rbf_network(X, beta, theta):
N = X.shape[0]
D = X.shape[1]
Y = np.zeros(N)
for i in range(N):
for j in range(N):
r = 0
for d in range(D):
r += (X[j, d] - X[i, d]) ** 2
r = r**0.5
Y[i] += beta[j] * exp(-(r * theta)**2)
return Y
Let’s make up some data
import numpy as np
D = 5
N = 1000
X = np.array([np.random.rand(N) for d in range(D)]).T
beta = np.random.rand(N)
theta = 10
Timing this in IPython
we get
%timeit rbf_network(X, beta, theta)
1 loops, best of 3: 11.5 s per loop
Dam those Python loops are slow!
scipy.interpolate.Rbf
So in this case we’re lucky and there’s an external numpy
based implementation
from scipy.interpolate import Rbf
rbf = Rbf(X[:,0], X[:,1], X[:,2], X[:,3], X[:, 4], np.random.rand(N))
Xtuple = tuple([X[:, i] for i in range(D)])
%timeit rbf(Xtuple)
1 loops, best of 3: 637 ms per loop
Much better. But what if we want to go faster or we don’t have a library we can use.
Cython
A Cython version - implemented in the file fastloop.pyx
- looks something like this
from math import exp
import numpy as np
def rbf_network(double[:, :] X, double[:] beta, double theta):
cdef int N = X.shape[0]
cdef int D = X.shape[1]
cdef double[:] Y = np.zeros(N)
cdef int i, j, d
cdef double r = 0
for i in range(N):
for j in range(N):
r = 0
for d in range(D):
r += (X[j, d] - X[i, d]) ** 2
r = r**0.5
Y[i] += beta[j] * exp(-(r * theta)**2)
return Y
So far all we’ve done is add some type declarations. For local variables we use the cdef
keyword. For arrays we use ‘memoryviews’ which can accept numpy arrays as input.
Note that you don’t have to add type declarations in a *.pyx
file. Any lines which use untyped variables will just remain in Python rather than being translated to C.
To compile we need a setup.py
script, that looks something like this
from distutils.core import setup
from Cython.Build import cythonize
setup(name="fastloop", ext_modules=cythonize('fastloop.pyx'),)
then we compile from the terminal with
python setup.py build_ext --inplace
which generates a C code file fastloop.c
and a compiled Python extension fastloop.so
.
Lets test it out
from fastloop import rbf_network
%timeit rbf_network(X, beta, theta)
10 loops, best of 3: 209 ms per loop
OK, but we can do a better. With Cython there are a few ‘tricks’ involved in achieving good performance. Here’s the first one, if we type this in the terminal
cython fastloop.pyx -a
we generate a fastloop.html
file which we can open in a browser
Lines highlighted yellow are still using Python and are slowing our code down. Our goal is get rid of yellow lines, especially any inside of loops.
Out first problem is that we’re still using the Python exponential function. We need to replace this with the C version. The main functions from math.h
are included in the Cython libc
library, so we just replace from math import exp
with
from libc.math cimport exp
Next we need to add some compiler directives, the easiest way is to add this line to the top of the file
#cython: boundscheck=False, wraparound=False, nonecheck=False
Note that with these checks turned off you can get segmentation faults rather than nice error messages, so its best to debug your code before putting this line in.
Next we can consider playing with compiler flags (these are C tricks rather than Cython tricks as such). When using gcc
the most important option seems to be -ffast-math
. From my limited experience, this can improve speeds a lot, with no noticeable loss of reliability. To implement these changes we need to modify our setup.py
file
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_modules=[ Extension("fastloop",
["fastloop.pyx"],
libraries=["m"],
extra_compile_args = ["-ffast-math"])]
setup(
name = "fastloop",
cmdclass = {"build_ext": build_ext},
ext_modules = ext_modules)
Now if we run cython fastloop.pyx -a
again we will see the loops are now free of Python
The yellow outside the loops is irrelevant here (but would matter if we needed to call this function many times within another loop).
Now if we recompile and test it out we get
from fastloop import rbf_network
%timeit rbf_network(X, beta, theta)
10 loops, best of 3: 42.2 ms per loop
OK, now we’re getting there.
Calling C functions
So what else can we do? Well it turns out the exponential function is a bit of a bottleneck here, even the C version. One option is to use a fast approximation to the exponential function
#include <math.h>
static union
{
double d;
struct
{
#ifdef LITTLE_ENDIAN
int j, i;
#else
int i, j;
#endif
} n;
} _eco;
#define EXP_A (1048576/M_LN2) /* use 1512775 for integer version */
#define EXP_C 60801 /* see text for choice of c values */
#define EXP(y) (_eco.n.i = EXP_A*(y) +<PHONE_NUMBER> - EXP_C), _eco.d)
From Cython its easy to call C code. Put the above code in vfastexp.h
, then just add the following to our fastloop.pyx
file
cdef extern from "vfastexp.h":
double exp_approx "EXP" (double)
So now we can just use exp_approx()
in place of exp()
. This gives us
from fastloop import rbf_network
%timeit rbf_network(X, beta, theta)
100 loops, best of 3: 15.3 ms per loop
The Wash-up
| Method | Time (ms) | Speed up |
|---|---|---|
| Python loops | 11500 | - |
scipy.interpolate.Rbf |
637 | 17 |
| Cython | 42 | 272 |
| Cython with approximation | 15 | 751 |
So there are a few tricks to learn, but once your on top of them Cython is fast and easy to use. Maybe not as easy as Python, but certainly much better than learning C.


I am a second year graduate student at UW-Madison. I received my bachelor's degree from BITS-Pilani, Goa in 2010.
I will be working with Mike Swift in fall 2016 (Project link is here). I will also be taking courses on Big Data and Distributed Systems. Apart from that I will also be working part-time with the awesome team at HTCondor.
My research interests are in operating system design, virtualization and distributed systems. I am interested in designing systems and strategies that will allow data centers of the future to scale to our ever increasing needs and make them power efficient. I hope to be able to contribute to the open agriculture initiative to help build a food data center.
Prior to starting graduate school I used to work at Qualcomm in the Wireless Connectivity Group where my primary area of concentration was the WLAN Data Path. Since all my professional experience was with mobile devices, it was a great opportunity for me to do an internship in ZeroStack in the summer of 2016. Here, I got to work on building a highly available private cloud solution and understand the complexities in designing the compute infrastructure for an enterprise.
News and Updates.
- Our talk on "Solving Redis Latency Issues with Transparent Huge Pages" was accepted in Redisconf 2016 [video]
- Accepted offer to join ZeroStack as an intern for summer, 2016

Dear participant,
You have some tasks to do today for the transplant study!
Visit https://mhealth-transplant.herokuapp.com/ to complete these tasks
Sincerely,
The {{ config.APP_NAME }} Team


See the Quickstart Guide for a quick start!
The MyBatis Generator user interface consists of these elements
The new configuration file wizard will create a new XML file with a basic outline of a configuration file for MyBatis Generator. You do not need to use this wizard, but it is useful for setting up a new configuration file.
You can access the wizard from the menu: "File>New>Other..., and then selecting "MyBatis Generator Configuration File" from the "MyBatis Generator" category.
The launch configuration is the heart of the Eclipse user interface. The plug-in will enable the "Run As>Run MyBatis Generator" option on any XML file that has the root element of "generatorConfiguration" or "ibatorConfiguration". To run MyBatis Generator, right click on a configuration file in any view and select the menu option.
The launch configuration has the ability to run a SQL script before running the generator. To access this functionality, you can edit the launch configuration with the normal Eclipse launch support. You can also add entries to the generator's classpath through the same launch configuration support. This should make it easier to access JDBC drivers, or to access your own generator plugins.
See the page Using the Launcher for more information about using the launcher.

Welcome to PayStubV2’s documentation!¶
Introduction¶
What is PayStubV2¶
PayStubV2 is a user-friendly program that enables a user to create any number of paystubs. This program can be used for work purposes or it can be used at your leisure as a forecasting tool to visualize potential pay. This tutorial shows you how to optimize the use of PayStubV2.

Note
If you do not have a Java compiler you can visit this site http://www.cs.utah.edu/~alee/cs51/penv/installJava
How to run PayStubV2 in command prompt:
- Press the windows button and R key simultaneously.
- Type cmd.exe in the open field.
- If that doesn’t work, then consider opening the command prompt from the start menu.
- Use cd command to modify working directory.
- If you want to navigate to the Sample folder within your Downloads folder, enter cd DownloadsSample.
- You can see what is in the current directory by typing dir and pressing enter.
- Compile the program by typing javac filename.java in the command line.
- Press enter
- During this process, if any errors are detected the command prompt will let you know.
- Now that the program is compiled, run the program by typing java filename.java.
- Press enter
Directions for using PayStubV2¶
Now that you’ve opened the program PayStubV2 in the command prompt, you are on your way to obtaining a paystub.
- Enter the employee’s name.
Note
Numbers can be entered in the name field, but it’s better to use just words.
- Enter the employee’s social security number.
- Words can be entered in the social security number field, but it’s better to use just numbers and dashes.
- It’s recommended that you don’t use your actual social security number. Instead, you can simply enter a value like 111-11-1111.
- Enter the number of regular hours worked.
Note
A common value for hours worked per week is for 40 hours but entering an amount that applies to you will give you a better prediction.
- Enter the number of overtime hours worked.
Note
If you did not work overtime hours, then this field is not applicable so you can simply enter zero.
- Enter hourly pay rate.
Note
For example, if you earn $12.25 an hour then you would enter twelve dot twenty five (12.25).
Now, the program branches into questions about overtime rate, social withholding, and federal tax.
- The default value of overtime rate is set to time and a half and to enumerate that we use the value 1.5.
- The default value of social withholding is set to ten percent and to enumerate that we use the value 0.1.
- The default value of federal tax is set to twenty percent and to enumerate that we use the value 0.2.
You as a user have the capability to change each of these fields to replicate your situation.
- Enter yes/no to change the overtime rate. If you want to keep the rate at its default value of 1.5, change nothing.
- Enter yes/no to change the social withholding rate. If you want to keep the rate at its default value of 0.1, change nothing.
- Enter yes/no to change the federal tax rate. If you want to keep the rate at its default value of 0.2, change nothing.
Your Paystub should display now! Now, you are prompted to enter another pay rate so that you can compare gross pay.
- Enter a new hourly pay rate.
Your new gross pay will display!
Note
If your new pay rate was greater than your previous pay than your gross pay should be greater than your previous gross pay. If your new pay was less than your previous pay than your gross pay should be less than your previous gross pay.
- Enter a positive integer to continue creating paystubs or enter zero to exit.

Hi I am Ivan, I am midwest boy through and though but living in sunny California. Currently I am an aspiring full stack developer, but in my very little free time I am shredding, drums, falling on a skateboard, and hanging out with friends. At a young age I was always a very curious person who loved to learn new things.
I am currently a full-time coding boot camp student enrolled in the Full Stack Flex program at UC Berkley. I grew up in Metro Manila, Philippines and currently living in San Francisco, California. I have a bachelor’s degree in Management of Financial Institutions from De La Salle University - Manila and take pride to be a part of the official dance organization of the university know as La Salle Dance Company - Street as well as taking leadership roles as the division manager for finance and the division manager for marketing. I am very excited as a new coder to follow into this career path and grab opportunities when presented! I'm definitely the type of person that gives 100% in everything I do and whatever challenges come at me and I believe we are forever students that we learn something new every day.
Hello! I'm Jonathan SanPedro and I am a student at the Berkeley Coding Academy. I graduated from Rutgers University in 2014 with a bachelors in Information Technology and Informatics. Since then, I've been working as an IT technician in multiple states. I recently moved to San Francisco and began teaching myself little bits of javascript and wanted to grow my skills further. I hope to gain the skills to become a developer and choose whatever career path I want!
