A powerful animation framework for iOS, tvOS, and OS X.
What is it?
Advance is a pure Swift framework that enables advanced animations and physics-based interactions.
Originally developed to power the animations throughout the Storehouse app for iOS, Advance has evolved into a composable set of tools with a simple API. It uses a CADisplayLink
instance to drive animations and simulations that advance on each frame.
Should I use it?
Advance shines when:
- You are building gesture-based interactions that use physics to reflect the behavior of the real world.
- You need to animate custom types with per-frame callbacks.
- ???. Advance is extensible, making it easy to build custom animation and simulation types.
You can accomplish amazing things with Advance. But you should be sensitive to the performance impact of performing per-frame animations on the main thread. Check out this article on objc.io for a good overview.
If you simply want to animate the basic properties of a view, it’s probably best to stick with UIView animations / Core Animation. It is able to run your animations on a high priority background thread and is not as sensitive to blocking the main thread.
Requirements
- iOS 8+, tvOS 9+, or OS X 10.10+
- Swift 2.2+
Examples
Check out the sample app.
Located in the project:
Animate between two numbers.
import Advance
0.0.animateTo(3.0, duration: 2.0, timingFunction: LinearTimingFunction()) { (value) in
print("value: \(value)")
// Do something with value
}
This will create and run an animation from 0.0
to 3.0
, calling the closure at each step of the animation.
Use Animatable
to contain values that can be animated with any animation type.
import Advance
class MyClass {
let center: Animatable<CGPoint>
init() {
...
center.changed.observe { (value) in
// Do something every time the center value changes
}
}
}
let foo = MyClass()
// foo.center.animateTo(...)
// foo.center.springTo(...)
// foo.center.decay(...)
// foo.center.animate(<custom animation type>)
Use Spring
to contain values that will only be driven by spring physics.
Instances of Spring
should be used in situations where spring physics are the only animation type required, or when convenient access to the properties of a running spring simulation is needed.
The focused API of this class makes it more convenient in such cases than using an Animatable
instance, where a new spring animation would have to be added each time the spring needed to be modified.
The Spring
class also serves as an example of how some of the internal components of the framework can be composed to build new components.
import Advance
let s = Spring(value: CGPoint.zero)
s.changed.observe { (value) in
// do something with the value when it changes
}
s.target = CGPoint(x: 100.0, y: 200.0)
// The spring will begin moving to the new value
// Some time in the future...
s.target = CGPoint.zero
// The value will come back to zero.
Animatable types
Any type conforming to VectorConvertible
can be animated.
public protocol VectorConvertible: Equatable, Interpolatable {
typealias Vector: VectorType
init(vector: Vector)
var vector: Vector { get }
}
VectorConvertible
is a simple protocol that allows instances of the the conforming type to:
- Define an associated type called
Vector
, which must be a concrete implementation ofVectorType
. Implementations of 1, 2, 3, and 4 component vectors are provided. - Be initialized with a
Vector
instance. - Provide a
Vector
representation of itself.
The associated type Vector
is a concrete implementation of VectorType
. For example, CGSize
defines the associated type as Vector2
(a two component vector, as size has a width and a height component):
extension CGSize: VectorConvertible {
/// The underlying vector type.
public typealias Vector = Vector2
/// Creates a new instance from a vector.
public init(vector: Vector) {
self.init(width: CGFloat(vector.x), height: CGFloat(vector.y))
}
/// Returns the vector representation.
public var vector: Vector {
return Vector(Scalar(width), Scalar(height))
}
}
Extensions are provided to add VectorConvertible
conformance to many of the types used in the UI layer. Animating custom types is as easy as adding an extension similar to the example above.
Design
Advance embraces composition and value types throughout.
There are a few foundational types at the core of the Advance framework:
Advanceable
protocol
Conforming types can be advanced on each frame by a given duration.
public protocol Advanceable {
mutating func advance(elapsed: Double)
}
Advanceable
is the mechanism by which all animations are performed. A typical device updates the screen 60 times per second – this means each frame has a duration of 0.016 seconds (1/60).
AnimationType
protocol
Inherits from Advanceable
.
public protocol AnimationType: Advanceable {
var finished: Bool { get }
}
Animations have a finite length (defined by each implementation). When the animation is complete, it returns true
for the finished
property.
ValueAnimationType
protocol
Inherits from AnimationType
.
public protocol ValueAnimationType: AnimationType {
typealias Value: VectorConvertible
var value: Value { get }
var velocity: Value { get }
}
Types conforming to ValueAnimationType
can be used to animate values of any type conforming to VectorConvertible
, as they support querying for the current value and velocity on each frame.
The framework includes the following animations:
BasicAnimation
uses a specified timing function and duration.SpringAnimation
uses aDynamicSolver
/SpringFunction
internally to animate to the final value.DecayAnimation
uses aDynamicSolver
/DecayFunction
internally to animate to the final value.
Please see the documentation and check out the sample app (AdvanceSample) in the project for more details.
Notes
Performance
Advance uses Swift generics extensively. This has many benefits, including the ability to natively animate nearly any value type without casting (or using NSValue
wrappers, etc).
The Swift compiler can heavily optimize generics through the process of specialization – in which it generates specific implementations of generic functions based on the way your code calls them. Unfortunately, specialization cannot occur between modules. This means that the compiler will be unable to fully optimize when Advance is built as a framework.
This probably does not matter in your application. Even with the small amount of overhead required to call generic functions, modern CPUs are fast; running a few animations will have little impact. If your application has many simultaneous animations, however, and you are looking for ways to optimize, you may see an improvement by bringing in all of the .swift files and compiling Advance as part of your project.
Thread safety
Advance classes are not thread safe, and expect to be used from the main thread only.
With that said, the majority of the framework is implemented as a set of protocols and value types. Because value semantics are implicitly safe to pass between threads, you can safely accomplish many things asynchronously. You just need to be sure that classes such as Animator
, Animatable
, and Spring
are accessed from the main thread only.
Status
Tests: More tests are needed. Test coverage is provided for some of the core types, but it is not yet comprehensive enough.
Documentation: Nearly every type is briefly commented, but expanding the documentation to include discussion and examples where appropriate is a goal of the project.
API Stability I currently consider the API to be in draft form (thus the < 1.0 version of the project).
Suggestions / pull requests / etc are welcome!
Usage
There are several ways to integrate Advance into your project.
Manually, as a framework: simply add the
Advance.xcodeproj
to your project and addAdvance.framework
as anEmbedded Binary
to your application target (under General in target settings). From there, addimport Advance
to your code and you’re good to go.Swift Package Manager (experimental).
Carthage: add
github "timdonnelly/Advance" "master"
to yourCartfile
.CocoaPods: add
pod 'Advance', '~> 0.9'
to yourPodfile
.

Preparation time
less than 30 mins
Cooking time
10 to 30 mins
Serves
Serves 4
Lentils are great; filling, warming and also full of iron. By blitzing half of the soup it will be thick and creamy, but still have texture from the remaining lentils.
Nutritional info: This recipe contains 267kcal, 5.7g fat (of which 1.2g saturates), 1.5g salt per portion. It counts as 2 of your 5-a-day.
First, make your vegetable stock. Grate the vegetables and place (along with any ends you can’t grate) into a large heatproof bowl. Add the thyme, bay leaves and the stalks from the parsley. Season with a small pinch of salt and pepper. Cover the vegetables with 1 litre/1¾ pints boiling water. Leave to steep for 10 minutes, or until cool. Once cool, strain the stock through a sieve and discard the vegetables.
For the main soup, heat the oil in a large saucepan or casserole over a medium heat. Add the onions and a pinch of salt. Fry gently for two minutes, then add the garlic and chilli and cook over a low heat for five minutes or until the onions are completely soft but not coloured. Add the bacon and fry for 2-3 minutes, or until cooked through.
Add the lentils and tomatoes, breaking up the tomatoes with your spoon. Cook for 2-3 minutes, then add enough of the vegetable stock to cover (you may need all of it). Bring to the boil then reduce to a simmer. Cook for 15-20 minutes, or until the lentils are completely soft. Turn off the heat.
Pour half of the soup into a blender and pulse until smooth. Return to the pan with the remaining soup and heat through, taste and adjust the seasoning if necessary.
Divide the soup between serving bowls, sprinkle with chopped parsley and serve.

TRAINSPOTTING A film review by Chad Polenz Copyright 1997 Chad Polenz
*** (out of 4 = good) 1996, R, 94 minutes [1 hour, 34 minutes] [crime/drama] starring: Ewan McGregor (Mark Renton), Robert Carlyle (Begbie), Johnny Lee Miller (Sick Boy), Kevin McKidd (Tommy), Ewen Bremner (Spud), produced by Andrew Macdonald, written by John Hodge, directed by Danny Boyle, based on the novel by Irvine Welsh.
Films about the destructive power of drugs all have the same message, but none of them dare to show how good drugs can make their user feel.  It allows us to share in the rush and escapism, but also the harsh consequences of it all.
The film starts out with tremendous energy with a fast-paced chase sequence and a narrator describing his escapist lifestyle. His name is Mark Renton (McGregor), a 20-something Scottish "wanker" who says he "chose not to choose life, instead... heroin."
 Renton's other friend Tommy (McKidd) doesn't touch the stuff (at first), but can't help being curious. Then there's Begbie (Carlyle), the nearly psychotic bully of the gang who gets his kicks from drifting and fighting. We don't know how these guys came together, but it's not relevant.
Boyle's direction is fantastic, much like Oliver Stone, he uses hyper editing techniques to define mood. No scene lasts longer than two minutes, in fact, most of them last less than 30 seconds. The story, just like the characters' lifestyle, is constantly shifting and never dwells on the obvious. There are scenes of moody drug parties, surrealistic clubs, quick, cheap sex, etc., all of which add up to a mood of pure nihilism.
Because everything happens so quickly, it would seem as if characterization would be sacrificed, but just the opposite is true. The erratic storytelling tells us all we need to know about the characters, showing how great their highs are, but how horrible their lows can be. There is one scene involving Renton and "The filthiest toilet in Scotland" that perfectly illustrates how pathetic drug addiction can be. It is so disguisting it's impossible not to squirm, but at the same time, the satire of it all is quite funny.
The film uses satire in a very surrealistic manner, much like Kubrick's "A Clockwork Orange." However, the reality here is more brutal than "Orange" because the narcotics are stronger and more addictive. When Renton tries to quit cold turkey there is a surrealistic montage so powerful it will probably be as close as a film ever comes in showing the devastating pain drugs can wreck on the mind.
Although there isn't much of a story to the film, the final act does try to set up what will probably be Renton and the gang's final scam. Not surprisingly, when Renton tries to go straight and clean, he has trouble doing so, and the same is true for the film's effort to tell a normal crime story. It doesn't make any major mistakes per se, it's just a bit too jumbled and overwhelming to take seriously.
The anti-drug message in "Trainspotting" is powerful, and its surrealistic style is impressive. Perhaps it could have been even more moving had it not been so strange, but it's still a good film for what it is.

| Dataset description: |
The selected Dataset is from kaggle which contains information about kickstarter-projects. The data was provided by a company based in Brooklyn, New York. This dataset is from the year 2018. My hope is that we will be able to analyse the dataset too obtain critical insights into the development of crow-funding projects. The dataset was filtered using python. The data that were extracted are the name of the project, the main category it belongs to, date it was launched, the current state of the project, the country where the project is based from and finally the amount of money they have received in USD. |
| Initial questions | Q1. Number of projects by category. |
| Description: | Above specifications will generate a bar chart which illustrates which category of projects are the most popular right now. Hovering over the category will provide us with the exact count for each category. |
| Insight: |
We can see that most of the kickstarter-projects are oriented towards entertainment.
The top catergory which generates the most number of projects is Games and the category with the least number of projects is Dance. The next category that is in demand is Technology. Out of all the projects most of them were made in Films & Vide, Music, Publishing, Games and Technology. These are the top 5 categories, with many projects when compareed to others. It is evident enough that people were very much interested in Media (Video, Film, and Music) category projects in year 2017 and early time of 2018. In this age when Gaming industry has generated more revenue than Hollywood, it is not surprising that there are a lot of kickstarter-projects related towards gaming.
This graph implies that most people have ideas relating to Media when they start out with a kickstarter-project. |
| Design considerations | For comparision of number of projects by category, a bar graph seems to be the most suitable candidate since we can see the values easily and the visualization is quite simple as well. The categories are on the Y-axis since it will be easy for the person viewing it to read and understand the axis labels.
|
| Data filtering and transformation: | Data Preprocessing & Filtering: Preprocessing is done using python and processed data is saved into new CSV file. 1. For preprocessing the data, loaded the data into pandas Dataframe. 2. Name of the project, the main category it belongs to, date it was launched, the current state of the project, the country where the project is based from and finally the amount of money they have received in USD were selected 3. Selected Data from just a 2 years and ignored the rest 4. Filled null values with Unspecified, Misc, 0-0-0 0:0, undefined, Other and 0 with the respective columns. |


This guide provides an overview of the HDFS Federation feature and how to configure and manage the federated cluster.
HDFS has two main layers:
The prior HDFS architecture allows only a single namespace for the entire cluster. In that configuration, a single Namenode manages the namespace. HDFS Federation addresses this limitation by adding support for multiple Namenodes/namespaces to HDFS.
In order to scale the name service horizontally, federation uses multiple independent Namenodes/namespaces. The Namenodes are federated; the Namenodes are independent and do not require coordination with each other. The Datanodes are used as common storage for blocks by all the Namenodes. Each Datanode registers with all the Namenodes in the cluster. Datanodes send periodic heartbeats and block reports. They also handle commands from the Namenodes.
Users may use ViewFs to create personalized namespace views. ViewFs is analogous to client side mount tables in some Unix/Linux systems.
Block Pool
A Block Pool is a set of blocks that belong to a single namespace. Datanodes store blocks for all the block pools in the cluster. Each Block Pool is managed independently. This allows a namespace to generate Block IDs for new blocks without the need for coordination with the other namespaces. A Namenode failure does not prevent the Datanode from serving other Namenodes in the cluster.
A Namespace and its block pool together are called Namespace Volume. It is a self-contained unit of management. When a Namenode/namespace is deleted, the corresponding block pool at the Datanodes is deleted. Each namespace volume is upgraded as a unit, during cluster upgrade.
ClusterID
A ClusterID identifier is used to identify all the nodes in the cluster. When a Namenode is formatted, this identifier is either provided or auto generated. This ID should be used for formatting the other Namenodes into the cluster.
Federation configuration is backward compatible and allows existing single Namenode configurations to work without any change. The new configuration is designed such that all the nodes in the cluster have the same configuration without the need for deploying different configurations based on the type of the node in the cluster.
Federation adds a new NameServiceID
abstraction. A Namenode and its corresponding secondary/backup/checkpointer nodes all belong to a NameServiceId. In order to support a single configuration file, the Namenode and secondary/backup/checkpointer configuration parameters are suffixed with the NameServiceID
.
Step 1: Add the dfs.nameservices
parameter to your configuration and configure it with a list of comma separated NameServiceIDs. This will be used by the Datanodes to determine the Namenodes in the cluster.
Step 2: For each Namenode and Secondary Namenode/BackupNode/Checkpointer add the following configuration parameters suffixed with the corresponding NameServiceID
into the common configuration file:
| Daemon | Configuration Parameter |
|---|---|
| Namenode | dfs.namenode.rpc-address dfs.namenode.servicerpc-address dfs.namenode.http-address dfs.namenode.https-address dfs.namenode.keytab.file dfs.namenode.name.dir dfs.namenode.edits.dir dfs.namenode.checkpoint.dir dfs.namenode.checkpoint.edits.dir |
| Secondary Namenode | dfs.namenode.secondary.http-address dfs.secondary.namenode.keytab.file |
| BackupNode | dfs.namenode.backup.address dfs.secondary.namenode.keytab.file |
Here is an example configuration with two Namenodes:
<configuration> <property> <name>dfs.nameservices</name> <value>ns1,ns2</value> </property> <property> <name>dfs.namenode.rpc-address.ns1</name> <value>nn-host1:rpc-port</value> </property> <property> <name>dfs.namenode.http-address.ns1</name> <value>nn-host1:http-port</value> </property> <property> <name>dfs.namenode.secondary.http-address.ns1</name> <value>snn-host1:http-port</value> </property> <property> <name>dfs.namenode.rpc-address.ns2</name> <value>nn-host2:rpc-port</value> </property> <property> <name>dfs.namenode.http-address.ns2</name> <value>nn-host2:http-port</value> </property> <property> <name>dfs.namenode.secondary.http-address.ns2</name> <value>snn-host2:http-port</value> </property> .... Other common configuration ... </configuration>
Step 1: Format a Namenode using the following command:
[hdfs]$ $HADOOP_HOME/bin/hdfs namenode -format [-clusterId <cluster_id>]
Choose a unique cluster_id which will not conflict other clusters in your environment. If a cluster_id is not provided, then a unique one is auto generated.
Step 2: Format additional Namenodes using the following command:
[hdfs]$ $HADOOP_HOME/bin/hdfs namenode -format -clusterId <cluster_id>
Note that the cluster_id in step 2 must be same as that of the cluster_id in step 1. If they are different, the additional Namenodes will not be part of the federated cluster.
Older releases only support a single Namenode. Upgrade the cluster to newer release in order to enable federation During upgrade you can provide a ClusterID as follows:
[hdfs]$ $HADOOP_HOME/bin/hdfs --daemon start namenode -upgrade -clusterId <cluster_ID>
If cluster_id is not provided, it is auto generated.
Perform the following steps:
Add dfs.nameservices
to the configuration.
Update the configuration with the NameServiceID suffix. Configuration key names changed post release 0.20. You must use the new configuration parameter names in order to use federation.
Add the new Namenode related config to the configuration file.
Propagate the configuration file to the all the nodes in the cluster.
Start the new Namenode and Secondary/Backup.
Refresh the Datanodes to pickup the newly added Namenode by running the following command against all the Datanodes in the cluster:
[hdfs]$ $HADOOP_HOME/bin/hdfs dfsadmin -refreshNamenodes <datanode_host_name>:<datanode_ipc_port>
To start the cluster run the following command:
[hdfs]$ $HADOOP_HOME/sbin/start-dfs.sh
To stop the cluster run the following command:
[hdfs]$ $HADOOP_HOME/sbin/stop-dfs.sh
These commands can be run from any node where the HDFS configuration is available. The command uses the configuration to determine the Namenodes in the cluster and then starts the Namenode process on those nodes. The Datanodes are started on the nodes specified in the workers
file. The script can be used as a reference for building your own scripts to start and stop the cluster.
The Balancer has been changed to work with multiple Namenodes. The Balancer can be run using the command:
[hdfs]$ $HADOOP_HOME/bin/hdfs --daemon start balancer [-policy <policy>]
The policy parameter can be any of the following:
datanode
- this is the default policy. This balances the storage at the Datanode level. This is similar to balancing policy from prior releases.
blockpool
- this balances the storage at the block pool level which also balances at the Datanode level.
Note that Balancer only balances the data and does not balance the namespace. For the complete command usage, see balancer.
Decommissioning is similar to prior releases. The nodes that need to be decommissioned are added to the exclude file at all of the Namenodes. Each Namenode decommissions its Block Pool. When all the Namenodes finish decommissioning a Datanode, the Datanode is considered decommissioned.
Step 1: To distribute an exclude file to all the Namenodes, use the following command:
[hdfs]$ $HADOOP_HOME/sbin/distribute-exclude.sh <exclude_file>
Step 2: Refresh all the Namenodes to pick up the new exclude file:
[hdfs]$ $HADOOP_HOME/sbin/refresh-namenodes.sh
The above command uses HDFS configuration to determine the configured Namenodes in the cluster and refreshes them to pick up the new exclude file.
Similar to the Namenode status web page, when using federation a Cluster Web Console is available to monitor the federated cluster at http://<any_nn_host:port>/dfsclusterhealth.jsp
. Any Namenode in the cluster can be used to access this web page.
The Cluster Web Console provides the following information:
A cluster summary that shows the number of files, number of blocks, total configured storage capacity, and the available and used storage for the entire cluster.
A list of Namenodes and a summary that includes the number of files, blocks, missing blocks, and live and dead data nodes for each Namenode. It also provides a link to access each Namenode’s web UI.
The decommissioning status of Datanodes.


 I stopped at a gas station to get some chapstick because i'd been doin some crank and my lips were dry as hell. While i was in there i saw a package that said dramamine and i remembered hearing somthing about tripping off of it but there were only twelve in a package so we went to wal-mart and got a big bottle of it for like 3 bucks so we got back to my house and each took 18 pills. I don't remember excatly how long it was probably an hour, and i saw smoke coming out of the wall. It was pretty cool but then later on we were out in the front yard with all these people that really weren't there. My mom got up at 1:00 in the morning and my friend was in the bathroom holding a towel talking to the wall, meanwhile i was out in the yard talkin to some of my friends i thought were there.
My friend thought he had to take these kids home so he left. i was going to go with him but there was no room. So i was by myself sitting in my car and two guys i'd never seen before were sitting in there with me, when i got up and went in the house for a minute, I came back and one of them was in the drivers seat. These were some scary lookin motherfuckers, and they were going to steal my car so i woke my parents up at 4:30 saying someone was stealin my car and my dad got up and ran out there. The door was open and the car was running but there was no one around so i made my parents stay up with me. I could hear them outside talking and i was like do you hear that? they said hear what, the guys are out there i said. They said there's no one out there, but i wouldn't belive them because i saw them and talked to them they seemed so real.
When i tried to go to bed this was around 5:30 is what my dad said.  My dad came in and looked around, but there was no one there. Finally i went to sleep, but thats not the end of it.
The next morning i woke up and mom said my friends mom had called and wanted to know if i made it home last night. She said yes. She wanted to talk to me but i was still asleep. She told my mom that she had to pick my friend up and he had no memory of what happened. Anyway when he had left to go take those people home he ended up at this house he thought was his aunt's and there was a party going on. This unfortuantly was not the case as it was 5:00 in the morning, and it was an old mans house just down the road. The man came outside and was yelling at him and for some reason he got in the man's car, all the people were still with him he thought. The guy called the cops and they came out and he ran. Of course they caught him because he didn't go very far and he just laid down he thought they couldn't see him even though they had flashlights right on him.
 He said he didn't know what happened, and they asked him what time it was. He said 10:30-11. They were like, no its 5:30 in the morning son. They released him to his mom and suggested he get drug tested. Cops always have good ideas like that. On the way home he was trying to eat the dashboard in his mom's car, and he thought i was driving. They couldn't find what he had been doing and he insisted he didn't know what happened so he didn't get in any trouble. Good thing the car was full of imaginary people or i would have been with him. It all came out ok and i think it was a good experience but i'll never do that shit again.

Huawei moving on 5G while politics plays out
by AFPSAN FRANSISCO: Major state telecom operators are rolling out 5G wireless advances in China as the country races to close a technology gap with the United States amid a bruising trade war.
The new-generation telecommunication networks move data at blazing speeds, promising economic and technological advantages to countries where they are deployed.
US regulators earlier this week proposed rules to block telecom carriers from buying from Chinese tech companies Huawei and ZTE, and to remove any of their equipment already in place to “safeguard the nation’s communications networks.”
The US Federal Communications Commission said the rules — to be voted on November 19 — were part of an initiative to “safeguard the nation’s communications networks.”
The two Chinese firms have been accused of posing a national security threat because of their close ties to the Beijing government. Both have repeatedly denied the allegations.
AFP sat down with Huawei US vice president of public affairs Joy Tan to ask her three questions:
Huawei has never had any major cybersecurity-related incidents.
I think targeting specific vendors based on country origins will not make America’s communication network more secure.
It will only impact rural operators and the most underserved areas in US.
So, we think this kind of action will further widen the digital divide and slow the pace of economic development, not make the network more secure.
On average we procure $11 billion in goods and services from US suppliers each year. These companies cannot continue to sell components or products to Huawei. I’ve seen their business impacted in the short term and in the long term, we’ll see a bigger impact for US companies as well.
$11 billion creates about 40,000 to 50,000 US jobs, so we hope these jobs won’t be impacted for the longer term.
South Korea and the US started launching 5G last year.
Already 3.5 million people are on 5G services.
China is moving very fast in terms of 5G deployment.
We continue to sign more contracts globally as well, Huawei is definitely leading the commercial deployment of 5G. 5G has come faster than all expected; we believe we are 12-18 months ahead of competitors.
Our most recent 5G base stations are shipped without any US components; (instead they come) with our own or components from other countries, so we’re not dependent on the US components
We want to work with them.
Huawei’s principle is always to collaborate with the best companies around the world, so that’s why we continue to want to engage with US companies.
If the US government allows big suppliers to continue to ship components, we’ll continue to buy from them, even if we have our own solutions and alternatives.
Harmony OS has a different purpose compared to Android or iOS.
When we designed it, we had the future in mind. It’s a lightweight, compact operating system, with powerful functionalities. We use that for smartwatches and smart screens in vehicles, and smart speakers first.
We definitely want to keep working with American companies including Google.
We continue to watch to see if Google will get a temporary license from the US government to continue to supply us. We hope we’ll see some good news next month or sooner.


Angular Library built on the top of the combination generator package of @udjamaflip. This library allows you to provide a list of characters and a min/max length of output string to generate a list of all possible combinations (or non-unique permutations of those characters). This is useful for getting a list of characters for brute-forcing or to test password combinations (e.g: for ngx-material-password-strength)

--- layout: archive title: Zulip Chat Archive permalink: /stream/113489-new-members/topic/Projective.20geometry.html ---
Is there any formalization of classical algebraic geometry in Lean? I'm mostly interested in projective geometry, at the level of what's covered in chapter I of Hartshorne, especially theorem I.7.7, about the intersection of a projective variety and a hypersurface not containing it.
If there is nothing like this, how much effort would it take to implement it, given what is already available? I'm reasonably familiar with typed functional languages (ML, Haskell), but dependently typed ones not so much. Thanks in advance.
no
which is a pain because I am teaching such a course next term.
so I'm going to have to write it myself. Want to help?
If you don't mind my potential slowness in learning the system, sure!
It will be a difficult task, but it is true that I will attempt to do it. Quite how far I will get I have no clue.
How much ring and field theory is already available?
Noetherian rings we have, basic stuff, I don't think anyone has done the Nullstellensatz yet, @Lennard Henze is working on Noether normalisation, we have Hilbert basis theorem
I just finished with this term's course yesterday so I was going to turn to this soon, but I need to tidy up my huge backlog of unread emails first.
Oh, okay.
I guess the positive side of the situation you describe is that, at least, I don't have to learn new mathematics to start contributing. I'm installing Lean right now. :-)
FYI here's the course outline from last year:
Course outline.
(1) Affine varieties – definition, examples, maps between varieties, translating
between geometry and commutative algebra (the Nullstellensatz)
(2) Projective varieties – definition, examples, maps between varieties, rigidity
and images of maps
(3) Dimension – several different definitions (all equivalent, but useful for
different purposes), calculating dimensions of examples
(4) Smoothness and singularities – definition, examples, key theorems
(5) Examples of varieties (depending on how much time is left)
What is not in the course?
(1) Schemes
(2) Sheaves and cohomology
(3) Curves, divisors and the Riemann–Roch theorem
I think we're always over an alg closed field.
I see, thanks.
when I'm done with Noether normalisation I want to turn to Nullstellensatz

Week 7 - nearly at the end of Phase 0. This weeks meditation asked deep questions. What motivates us to do whatever it is that we do?
How does life look through the 'pleasure, passion and purpose' lens?
If you live your life from the perspective achieving your higher purpose, the other two tend to follow. It can energise and excite you and it gives your work and life meaning. Unfortunately given the way we live nowadays, we don’t always take time to discover this for ourselves.
We can easily confuse passion and things which give us pleasure with what drives us forward but it’s not until we stop and ask the question why and what for that think about this. Those two elements are important but long term are not sustainable. They encourage us to grasp and accumulate.
In my own life, I am still trying to discover what my higher purpose is. I wonder if it can change. I ‘ve come to the realisation that the answer really comes from alignment of your own core principles and values with your work and community, then you are on your way.
From the 'discovering values and higher purpose' exercise, what are your core values and what do you stand for?
My core values are
- Honesty
- Empathy & Understanding
- Compasssion
- Kindness
- Sustainablity
- Personal freedom and choice
- Community
How did you find the resilience ideas and meditation exercise?
I like the idea of how we can build our resilience through our meditation practice. Understanding that the uncomfortable feeings associated with disappointment or difficult situations are physiological reminds us that they are only fleeting and will pass. Reinforcing with positive thoughts and anchoring with previous success builds on the idea that we can bounce back from adversity.
Adopting a forward looking, optimistic view and a willingness to accept and move on from our failures will serve us better than dwelling on them and holding us back.

General Cohort Info
The xAPI Learning Cohort is a free, vendor-neutral, 12-week learning-by-doing project-based team learning experience about the Experience API. It’s an opportunity for those who are brand new to xAPI and those who are looking to experiment with it to learn from each other and from the work itself.
xAPI Learning Cohorts run twice a year in spring and fall “semesters” or "seasons".
Work and participation happens synchronously in the Weekly Live Session, and asynchronously in Slack and GitHub.
Weekly Live Session
Weekly live sessions are held every Thursday at 2pm US Eastern during an active season (spring or fall).
For 2021/2022, our live sessions are held in Airmeet.
Weekly Updates
After the live sessions, a weekly update (with links to recordings, etc.) is sent via email.
Cohort Teams
Each Cohort season, Teams will be formed, starting a few weeks into the season. Sometimes a Team will continue work from a previous season, building upon their own efforts or that of a previous group. Other new Teams will form as participants start to narrow down a focus, either by polling the group or creating them on their own and seeing what sticks.
You are under no obligation to join a Team. You can join the Team's Slack channel and just lurk but not actively participate, if perhaps you're not ready but are interested in the topic or want to follow along.
Often there is an informal (and sometimes formal) Team Leader, though the only representative officially asked for is someone who can give a rundown of their activity in weekly Team updates to the broader Cohort.


B.C. Transit advisories for Greater Victoria on Friday morning
by Cindy E. HarnettB.C. Transit initially said four trips were potentially cancelled this morning, but updated its advisory with the following trips running after all:
- 4 UVic – from Downtown at 8:22 a.m.
- 50 Downtown – from Langford Exchange at 7:56 a.m.
- 50 Langford – from Downtown at 8:55 a.m.
For more information, go to B.C. Transit's advisory page.
The transit system was plagued with cancellations in September and October as mechanics struggled to keep Victoria’s aging fleet on the road.
B.C. Transit borrowed seven buses from Abbotsford and Kelowna in an attempt to prevent trip cancellations on Greater Victoria routes.
The two-year-old buses — four from Abbotsford and three from Kelowna — were hoped to help improve the reliability of bus service, according Kevin Schubert, general manager of B.C. Transit’s Victoria operation.
B.C. Transit is still delivering more than 99 per cent of its scheduled services every day, which includes 3,200 trips on weekdays, according to spokesman Jonathon Dyck.
There are 302 buses in the fleet, based in Victoria and Langford.
B.C. Transit’s Victoria operation saw an almost 10 per cent increase in ridership in September, year-over-year. Ridership on the No. 50 bus from the West Shore to downtown Victoria has jumped 44 per cent in five years.
In 2020 there will be 80 new buses, which will reduce the average fleet age from 12 years to six years. A significant percentage of the new buses will operate on compressed natural gas. Ten electric buses are scheduled to arrive in 2021.
The borrowed buses from Abbotsford and Kelowna will be returned when Victoria’s new buses arrive.

This page will prove what parts of my code possess Inheritance, Abstraction, Encapsulation, Polymorphism
The part of my calculator_v2 project that would represent Polymorphism would be in calc_test.py. The rationale behind my logic is that I can create multiple tuples that are used in the same function call. Theoretically, I can run addition or any other operation as many times as I want through calc_test.py and that will keep providing me with new values for the results. I even added a new method to validate the process. Therefore, the entire calc_test.py file serves as a means of Polymorphism.
With the pictures given, the "test_calc_polymorphism" function was made to prove that I can make two separate tuples that can run the same math operation. In my case, I used addition since it was easier. However, that testing can be applied to the other operation. The pylint check validates that there is no error with both tuples be added. I do believe that concept works in history_test.py with the function that can remove a value from the list of calculation.
The part of my calculator_v2 project that would represent Inheritance would be in the operations directory . This directory possesses all the operations including calculations.py. This file is what takes in the tuples that are inputted. It is the addition class from addition.py that would use the tuples from the calculations class from the calculations.py file. The same applies for all the other operations in that directory.
The pictures depicts the process to complete a given operation. When calc_test.py runs the addition operation, the addition class will send the tuple over to the calculations class for addition to be able to add the values with the tuple. The addition class inherits the values with the tuple from the calculations class.
As seen from the sections prior, the calculator_v2 project possesses attributes of Object-Oriented Programming. This section is no different. This section is about Encapsulation, but what part of my code protects data from direct modification? It is quite simple because that lies in the operations the return the value. The tuples are taken and perform the desired operation, and we get the result. Yet, we cannot modify that result. While those values can be purged from the history list, it's the history list that is getting modified. Therefore, those result values are never modified.
Yes it is the same picture used in the Inheritance section. The sum that is generated is accessed or modified. It is stored in a list that contains the sum. The list can remove the value from itself which indirectly modifies the sum to not exist.
The last attribute to talk about in Object-Oriented Programming is Abstraction. Although my files do not possess abstract classes or methods, it does do a good job at displaying what is needed. This is mainly evident in both calc_test.py and history_test.py. Both files just show the user that do math operations and modify the history list. Thus, it makes both files not very complex.
The level of complexity increases when having to keep track of what each function does when a user does not understand what the programmer made. At one point, both testing files were merged into one file. The same applies for the calculate.py and calculations.py from the history directory. Although I know how to easily maneuver that code, a simple user would not understand and simply not use the program due to its high level of complexity.

Standard (?) orientation of polar coords in radar data


It provides me with great joy to recollect this memory - I use it as a way of transcending the states, a device to reconnect with the way that I felt on that evening. On that occasion, I had departed from the narrow channels of thought to which an everyday existence is suited and had begun to think in enormous terms, about the world and the universe and the meaning of existence. I'm the closest I've ever been to figuring it all out.
A friend of mine held a party in the winter months, some time earlier this year. It was to be a celebratory event filled with my closest friends and acquaintances. I had hoped that I might bring two friendship groups together. In particular, I wanted my best friend, S to integrate with others that I was close with. It is important for me to note that this experience was unplanned but developed in to an event of heightened spiritual discovery in the sense that it allowed me to learn a great deal about the way that the world functions and the way that human beings interact with one another.
When S and I arrived at the party, he quickly became involved in conversation and I was relieved that the others had accepted him so readily. I drank three bottles of beer in the first hour and a half of the evening, which may of aided my relaxation but to my memory, it was not significant to the overall experience. My friend S later proposed that we do some MDMA - others were acquainted with the drug and had used it a number of times in the past. This would be my first experience of the drug.
At around 2230, five of us gathered in the bathroom. The individuals present were myself, my best friend S, and three other boys, L, A and E. I consumed my dose (Approx 100mg) orally, wrapped in a thin piece of tissue and then taken with water.
I recount that this was a very pleasant way to take the drug.
Ten minutes later I went downstairs to get some fresh air and to talk to some people outside. When I entered the house again, the music greeted me with its pleasant changes in melody and rhythm. I became excited at the change in state - which wasn't immediately distinguishable, but I began to examine the smaller changes in my behavior, a fondness for everything - and at this point I realised that I needed to find the others, to reconnect with them and to share the rise together.
Somehow, the events of an evening took place in one room - the bathroom. The five of us sat in there, talking about our experiences and how happy we were to be together. Inhibitions faded, anxieties disappeared all together. I sat in between S and A, with my hands on the back of their necks, uninhibited or burdened by physical boundaries. In this sense, personal space was not so important - I wanted to share mine with everyone else. I wanted to touch openly and to use this as a tool to express my love for others. It is impossible to describe fully how I felt in these moments, but it was as though a deep social boundary had been lifted. I openly told my friends how handsome they were. They were happy to be complimented in such an open way.
Later, at about 3 am, we all went downstairs to talk to other people from the party who had not been using the drug. This was quite an unsettling experience because I noticed how numb and unreceptive they were to me and the four others who had used the drug. When using MDMA, I found that I wanted everyone to be as happy as I was, and to be as open and honest as I felt, but sadly, this is not always possible. For me, the most pleasant experience came later on in the evening when the five of us decided to take a walk. We walked to the top of a large ridge in front of a lake and by this point, it was beginning to get light again. I must have peaked around this time because I remember feeling immensely happy and connected with those around me. When I returned home, I wrote a short passage detailing the moments on top of the hill. This was what I wrote:
As I gazed in to the vastness of the world before me, I began to feel overwhelmed by the beauty of the land. I felt humbled by the presence of the people in my company, grateful that they were beside me and were experiencing this journey with me. I was distinctly aware of the magnificence of this place, there was a great sense of privilege in being allowed to appreciate the splendour that belonged to the lake. I recounted those feelings that I had felt in the hours before. I felt a deep connection to those who stood on that ridge.
There was a heightened sense of things in this place. A clarity unknown to me before. I felt a bond resonate among us. I remember thinking that the greatest thing a man has to fear is loneliness. Humans are made for each other. My experience was my own but it was shaped by a feeling of divine unity. In these moments, I seemed to have a greater capacity to appreciate and to love. I noticed the reflection of cotton like clouds in the body of water before me. A rising mist in the trees ahead gave the impression of distance and enormity. I allowed myself time to consider each feature carefully, studying the subtle qualities and finding pleasure in this discovery.
Later, I would descend down the ridge with great speed. A child running down a hill slows to avoid injury. Here, I was not governed by fear. I would place massive strides, noticing each time that my steps were a greater distance apart and that I was indeed travelling with enormous speed. I felt the feathery wind brush my cheeks as I ran. I felt great ecstasy in being freed of my immediate fears. I was no longer inhibited by the anxiety of tripping or falling.
Sharing this experience and knowing that others had felt the same way in those moments meant that my happiness was multiplied. I knew that I had a responsibility to remember this for all of us. A feeling of bravery and excitement soon arose and I began to think about the passing of time and the future. Thoughts of others were prominent in a time of self-reflection and contemplation. I began also to think of the trivial nature of substance and property – I could discern that the company of others leads to a higher joy than these things can provide.
In these moments, I was able to look towards the future with wonder. I trusted the cerulean horizon as it told me that great things would be delivered to me. This has stayed in my mind for a long time. I don't think it is a night that I will ever forget.
I learned from this experience is that we all have the ability to transcend the states of consciousness until we arrive at a point where we are able to think in such a massive and altering way. A lot of people use drugs as a means to do this. To me it is important to remember that I can do this on my own. MDMA just helped me learn how. I feel as though I appreciate some things more now - friendship and personal relationships and the positive influence that the environment has on me.
Ultimately, I realised that the only thing that can provide me with happiness in this life is other people. Material property seems irrelevant and void to me. I live to give everything I have, my entire being, to another person unconditionally. That's the reason I'm alive.

More Tiles
In all of our examples we have loaded tiles by hand. We did breafly look at how to use tools to generate some understandable data, but it only goes so far. Let's leave off with an easy to parse map format. In this chapter we're going to load maps.
Define a format
I want you to come up with a map format! Each map will contain ONLY 1 room. Door tiles can go to other maps, how you represent those maps is up to you (By number, by string, or by whatever).
Here is what a format might look like:
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
1 0 3 3 3 0 0 0 0 0 0 0 0 0 1
1 0 3 3 3 0 3 3 3 3 3 3 3 0 1
1 0 0 0 0 0 3 3 0 0 0 0 3 0 1
1 0 3 3 3 0 3 3 3 0 3 3 3 0 1
1 0 3 3 3 0 0 0 0 0 0 0 0 0 2
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
T Assets/TileSheet.png
R 0 23 87 98
R 1 23 87 98
R 2 23 87 98
R 3 23 87 98
W 0 2
D 2 Assets/NextRoom.txt
S 2 1
I assume NO HEIGHT in my map format. In this hypothetical format, blank lines are skipped. Any line that begins with a number records a row. Any line that starts with a letter starts some meta-data. Here is my meta data format:
- T [Path]
- Specifies where the texture for this sheet is loaded
- R [index] [x] [y] [w] [h]
- Specifies the source rectangle
- index - which tile are we specifying the source of (0, 1, 2...)
- x, y, w, h - rectangle size
- W [index list]
- Specifies which tiles are walkable
- Takes a list of integers, any integer in the list is walkable
- D [Index] [Path]
- A door tile!
- The first argument is the index. In this map, tile 2 is a door
- The second argument is another map file! Load this map file when the door is entered
- S [x] [y]
- Specifies the starting tile for this map.
- When the map first loads, place the hero here.
There is no requirement for this. You can include as many or as few items in your map as you want (You don't have to have doors unless you want to). Feel free to use my proposed format as a jumping off point.
Loading the map
Right now we are hard coding the map layout into Game.cs, this needs to change. Change the constructor in Map.cs to take a single string for it's argument. This string should be the path of the map file to load. All map info needs to be in this file!
You should craft a map file by hand, then modify the constructor of Map
and try loading that file.


My previous post drew some attention, and in particular two comments I wish to relate to. I also wish to make a more fine-grained observation on visual editors.
One comment is by Peter Laursen, who rejected the generalization in my post, and another by wlad, who was harsher (but to the point), suggesting my post translated to "I don't know it, therefore it sucks".
I must have delivered the wrong message, since apparently people read my post as "don't use visual editors, they are bad for you", which is not what I intended to say, nor is it what I actually think. I took a very specific aspect of visual editors and commented on that. My comment should not extrapolate to "anything about visual editors is bad".
I don't think people should only be using the command line, and am not in the least interested in vi/emacs/eclipse/netbeans kind of wars. Of course everyone should be using whatever works best for them in terms of productivity and ease of use. And of course visual editors have great advantages over command line.
I'm sorry, it would be childish to assume otherwise, and extra-extra-extrapolation to suggest that was my hidden meaning.
Reflections on Peter's comments
I can see that my post was harsh on visual editors, and agree one cannot just generalize on the dozens of editors available. I have used a few tools, and only to some extent, since I personally feel more comfortable with command line, and so I cannot possibly generalize on all tools. Nor are they all equal.
My point is, there is one de-facto tool, which is the command-line, for which there are no hidden assumptions. For which I don't need to investigate whether a new connection is being opened, or if my query is somehow modified, or... I guess one can say "hey, my tool does nothing of the sort and acts just like the command line". I'm not arguing. The visual editor is an additional layer between you and the server (the mysql command line client is in itself a layer, but a very transparent one, a very low level one), one which needs to take care of visual issues, such as display space, GUI components, widgets not running out of memory, responsiveness, good looks. These, one way or the other, add complexity to the discussion between yourself and your database.
One can say "it's all configurable, there's good documentation, you should know the tool you are using". To some extent the same can be said of the command line client. Here is an observation of mine, please consider it as user input: many (I don't know if most) users will not bother modifying the settings. Many will feel uncomfortable with turning checkboxes on and off, or modify thresholds. It is similar in essence to users not modifying the default InnoDB settings for the MySQL server, working with 8MB of buffer pool.
Anyway I agree my post was over-generalizing on the criticism of visual editors. Sorry for that. It should have been more specific on the advantages of command line.
Reflections on wlad's comments
Since I wanted to concentrate on the command line issue, I didn't elaborate on other stuff. For example, I didn't specify on what type of trainings I ask students to close down their visual editors and open up a command line. Perhaps one could read as "from this moment on, and for the entire duration of the training, no one should be using visual editors, and anyone who does will find himself/herself out of the class". I really didn't think to elaborate on that, and even now - wow, it will take me ages to tell the full story. So I will be extra-brief:
I do make that suggestion. I do that when I start discussion of keys & execution plans. I don't enforce that. I don't mind which tool a developer uses. I actually tell them about various GUI tools they can use (naming the ones I see as most popular among other students).
But I also do not turn my training to "I'm going to do this session using the same tools you are using just because you are using them and you are in this class".
There is a multi-layered reasoning for that:
- Many times there is a mixture of tools in the classroom. I can't just pick up on one. The command line is the most common tool everyone can agree upon. I sometimes demonstrate on MySQL Workbench since many are familiar with it being an "official" GUI tool by the same company which makes the database.
- If I dwell on the particulars of a GUI tool, this consumes precious time that must be used to explain the EXPLAIN and talk about INDEX in depth. I just don't have that time on training. The command line consumes very little time for me.
- I also don't see that I should demonstrate using commercial products. I have nothing against commercial, and on occasion I buy commercial, and I certainly do not slight a commercial product just because it's commercial, but I prefer to sponsor open source. If students have a commercial product, I don't see this is my duty to walk them through the product.
- There are actually a few more reasons; operating systems, installations, assumptions on installed software, strict system administrators who would not installed anything I would tell them, projectors, font sizes, contrast of colors on projected image, ... Believe me, I've been doing this for years, there are many factors to any small decision in class.
Last, I wish to relate to wlad's "I don't know it. It sucks" attribution to my post.
It is true there is not one single SQL GUI tool I know bottoms up. And the status is deteriorating, since I've long since decided my personal preference is command line. This makes me a non-expert, no-authority on any GUI tool. I actually present myself as such in class. This does not lower the quality of the training; it's an aspect outside the training (for the reasons I mentioned above). I therefore agree to "I don't know it".
Now, I strongly believe I do not make the connection to "therefore it sucks". I think that's an exaggerated extrapolation of what I said. But it is such an overwhelming statement about myself for me to read, that I will keep it in mind. It's a good thing to keep in mind, not only on GUI tools, but also in real life.

public class PushBasedFetchHelper
extends Object
implements org.apache.spark.internal.Logging
ShuffleBlockFetcherIterator
that encapsulates all the push-based
functionality to fetch push-merged block meta and shuffle chunks.
A push-merged block contains multiple shuffle chunks where each shuffle chunk contains multiple
shuffle blocks that belong to the common reduce partition and were merged by the
external shuffle service to that chunk.| Constructor and Description |

2) ShuffleBlockFetcherIterator.FallbackOnPushMergedFailureResult
3) ShuffleBlockFetcherIterator.PushMergedRemoteMetaFailedFetchResult |
boolean |
isLocalPushMergedBlockAddress(BlockManagerId address)
Returns true if the address is of a push-merged-local block.
|
boolean |
isPushMergedShuffleBlockAddress(BlockManagerId address)
Returns true if the address is for a push-merged block.

iterator.next()
is invoked and the iterator
processes a response of type:
1) ShuffleBlockFetcherIterator.SuccessFetchResult
2) ShuffleBlockFetcherIterator.FallbackOnPushMergedFailureResult
3) ShuffleBlockFetcherIterator.PushMergedRemoteMetaFailedFetchResult
This initiates fetching fallback blocks for a push-merged block or a shuffle chunk that failed to fetch. It makes a call to the map output tracker to get the list of original blocks for the given push-merged block/shuffle chunk, split them into remote and local blocks, and process them accordingly. It also updates the numberOfBlocksToFetch in the iterator as it processes failed response and finds more push-merged requests to remote and again updates it with additional requests for original blocks. The fallback happens when: 1. There is an exception while creating shuffle chunks from push-merged-local shuffle block. See fetchLocalBlock. 2. There is a failure when fetching remote shuffle chunks. 3. There is a failure when processing SuccessFetchResult which is for a shuffle chunk (local or remote). 4. There is a zero-size buffer when processing SuccessFetchResult for a shuffle chunk (local or remote).
