Python has 3 main types of data structures for storing collections of items - lists, sets, and dictionaries. It’s important to know that the access speed of a list is O(n), that is it takes longer and longer to check something as the list gets longer. Sets and dictionaries have O(1) access, which means that the access speed is the same regardless of the size of the collection.
Consider if we have a list of ground-truth items and a list of candidates and we want to check if each of the candidates is in the ground truth:
import random
import timeit
# This is a list of 10k random items as an example
small_groundtruth = [random.randint(1, 1000000) for x in range(10000)]
def check_candidates(groundtruth, n_candidates):
"""Check which of the candidates in the range [0-n_candidates]
are present in the collection `groundtruth`"""
yes = []
no = []
for candidate in range(n_candidates):
if candidate in groundtruth:
# This is just an example about what to do with the result
yes.append(candidate)
else:
no.append(candidate)
We can use the timeit module (from tip 1!) to see how long our method takes:
timeit.timeit('check_candidates(small_groundtruth, 100)', number=10, globals=globals())
0.13829218316823244
OK, so checking 100 candidates in a list of 10k items 10 times (the number parameter) takes 0.14 seconds (0.01 seconds per iteration), this seems pretty fast. What happens if we want to check 1000 items?
timeit.timeit('check_candidates(small_groundtruth, 1000)', number=10, globals=globals())
1.3406621366739273
Time increases linearly. However, what happens if our groundtruth grows by some orders of magnitude?
# 100k items
groundtruth = [random.randint(1,<PHONE_NUMBER>) for x in range(100000)]
timeit.timeit('check_candidates(groundtruth, 100)', number=10, globals=globals())
1.36269876267761
timeit.timeit('check_candidates(groundtruth, 1000)', number=10, globals=globals())
13.427033469080925
# 1m items?
groundtruth = [random.randint(1,<PHONE_NUMBER>) for x in range(1000000)]
timeit.timeit('check_candidates(groundtruth, 1000)', number=10, globals=globals())
122.46592588163912
This is getting longer and longer. Why is this the case? When testing for membership in a list, we have to check every item in the list in order to see if a candidate exists. If the item doesn’t exist in the list we have to check all items in the list before we can say that it doesn’t exist. As this list gets longer and longer, this operation takes longer. We can speed up the process by checking if the item is in a set instead of a list:
groundtruth_set = set(groundtruth)
timeit.timeit('check_candidates(groundtruth_set, 1000)', number=10, globals=globals())
0.0022530462592840195
The same operation which took 122 seconds above (12 seconds per number) only took 0.002 seconds! (60,000 times faster!) What happens if we make the groundtruth 100x larger?
# These two lines take a while to run, but it's just one-time setup for the demo
groundtruth100m = [random.randint(1,<PHONE_NUMBER>000) for x in range(1000000000)]
groundtruth100m_set = set(groundtruth100m)
timeit.timeit('check_candidates(groundtruth100m_set, 1000)', number=10, globals=globals())
0.0023570358753204346
It takes the same amount of time! No increase as the size of our groundtruth grows. This is because the check uses the hash of its value to quickly see if the item exists in the set (https://docs.python.org/3.7/library/stdtypes.html#set-types-set-frozenset)
The key of a dictionary is also a hash, and so your groundtruth in this example could also be a dictionary mapping {value: class} and the lookups would still be fast.
Note that the process of changing a list to a set may take some time, but the tradeoff is worth it to get fast lookups multiple times. Make sure that you only do it once! It will cause you to use more memory. Remember that a set is not ordered, and can only contain a value once. To save time and memory, consider generating the set initially instead of making a list and converting it.

Datatables
DataTables is a plug-in for the jQuery Javascript library. It is a highly flexible tool, build upon the foundations of progressive enhancement, that adds all of these advanced features to any HTML table.
Zero configuration
DataTables has most features enabled by default, so all you need to do to use it with your own ables is to call the construction function: $().DataTable();.

Hidden columns
DataTables allows ordering by multiple columns at the same time, which can be activated in a number of
There are times when you might find it useful to display only a sub-set of the information that was available in the original table. For example you might want to reduce the amount of data shown on screen to make it clearer
for the user (consider also using the Responsive
extension for this). This is done through the columns.visible
column option.
Complex headers (rowspan and colspan)
When using tables to display data, you will often wish to display column information in groups. DataTables fully supports colspan
and
rowspan
in the table's header, assigning the required order listeners to the TH element suitable for that column.

DOM positioning
When customising DataTables for your own usage, you might find that the default position of the feature elements (filter input etc) is not quite to your liking. To address this issue DataTables takes inspiration from the CSS
3 Advanced Layout Module and provides the
dom
initialisation parameter which can be set to indicate where you wish particular features to appear
in the DOM. You can also specify div
wrapping containers (with an id and / or class) to provide complete layout flexibility.

Alternative pagination

the end user. This is done through DataTables' extensible pagination mechanism, the pagingType
option.

Scroll - vertical
This example shows the DataTables table body scrolling in the vertical direction. This can generally be seen as an alternative method to pagination for displaying a large table in a fairly small vertical area, and as such pagination has been disabled here (note that this is not mandatory, it will work just fine with pagination enabled as well!).

Scroll - vertical, dynamic height
This example shows a vertically scrolling DataTable that makes use of the CSS3 vh
unit in order to dynamically resize the viewport based on the browser window height. The vh
unit is effectively a percentage of the browser window height. So the 50vh
used in this example is 50% of the window height. The viewport size will update dynamically as the window is resized.

Scroll - horizontal
DataTables has the ability to show tables with horizontal scrolling, which is very useful for when you have a wide table, but want to constrain it to a limited horizontal display area. To enable x-scrolling simply set the
scrollX
parameter to be whatever you want the container wrapper's width to be (this should be
100% in almost all cases with the width being constrained by the container element).

Language - Comma decimal place
A dot (.
) is used to mark the decimal place in Javascript, however, many
parts of the world
use a comma (,
) and other characters such as the Unicode decimal separator (⎖
) or a dash (-
) are often used to show the decimal place in a displayed number.

Properties
- cached : bool
- color : color
- cornerRadius : real
- glowRadius : real
- spread : real
Detailed Description
This effect is intended to have good performance. The shape of the glow is limited to a rectangle with a custom corner radius. For situations where custom shapes are required, consider Glow effect.
| Effect applied |
|---|
Note: This effect is available when running with OpenGL.
Example
The following example shows how to apply the effect.
import QtQuick 2.0 import QtGraphicalEffects 1.0 Item { width: 300 height: 300 Rectangle { id: background anchors.fill: parent color: "black" } RectangularGlow { id: effect anchors.fill: rect glowRadius: 10 spread: 0.2 color: "white" cornerRadius: rect.radius + glowRadius } Rectangle { id: rect color: "black" anchors.centerIn: parent width: Math.round(parent.width / 1.5) height: Math.round(parent.height / 2) radius: 25 } }
Property Documentation
This property allows the effect output pixels to be cached in order to improve the rendering performance.
Every time the source or effect properties are changed, the pixels in the cache must be updated. Memory consumption is increased, because an extra buffer of memory is required for storing the effect output.
It is recommended to disable the cache when the source or the effect properties are animated.
By default, the property is set to false
.
This property defines the RGBA color value which is used for the glow.
By default, the property is set to "white"
.
| Output examples with different color values | ||
|---|---|---|
| color: #ffffff | color: #55ff55 | color: #5555ff |
| glowRadius: 20 | glowRadius: 20 | glowRadius: 20 |
| spread: 0 | spread: 0 | spread: 0 |
| cornerRadius: 25 | cornerRadius: 25 | cornerRadius: 25 |
This property defines the corner radius that is used to draw a glow with rounded corners.
The value ranges from 0.0 to half of the effective width or height of the glow, whichever is smaller. This can be calculated with: min(width, height) / 2.0 + glowRadius
By default, the property is bound to glowRadius property. The glow behaves as if the rectangle was blurred when adjusting the glowRadius property.
| Output examples with different cornerRadius values | ||
|---|---|---|
| cornerRadius: 0 | cornerRadius: 25 | cornerRadius: 50 |
| glowRadius: 20 | glowRadius: 20 | glowRadius: 20 |
| spread: 0 | spread: 0 | spread: 0 |
| color: #ffffff | color: #ffffff | color: #ffffff |
This property defines how many pixels outside the item area are reached by the glow.
The value ranges from 0.0 (no glow) to inf (infinite glow). By default, the property is set to 0.0
.
| Output examples with different glowRadius values | ||
|---|---|---|
| glowRadius: 10 | glowRadius: 20 | glowRadius: 40 |
| spread: 0 | spread: 0 | spread: 0 |
| color: #ffffff | color: #ffffff | color: #ffffff |
| cornerRadius: 25 | cornerRadius: 25 | cornerRadius: 25 |
This property defines how large part of the glow color is strenghtened near the source edges.
The value ranges from 0.0 (no strenght increase) to 1.0 (maximum strenght increase). By default, the property is set to 0.0
.
| Output examples with different spread values | ||
|---|---|---|
| spread: 0.0 | spread: 0.5 | spread: 1.0 |
| glowRadius: 20 | glowRadius: 20 | glowRadius: 20 |
| color: #ffffff | color: #ffffff | color: #ffffff |

Jennifer Aniston teases the 'Friends' cast is 'working on something' together
by Entertainment DeskJennifer Aniston has hinted at a mystery project that she and the rest of the Friends cast are apparently working on. She kept saying that “something is happening” in an attempt to avoid further grilling on what that may be.
The 50-year-old actor had been speaking on The Late Show with Stephen Colbert on Tuesday evening, reported Daily Mail.
Aniston was questioned why she had teased fans with news of the potential project on The Ellen DeGeneres show earlier. She admitted that there is indeed something coming in the future, except she just doesn’t know what it is yet.
“I make noises,” she said playfully. “I just make noises. Just like that. I said, ‘Something is happening.’ I don’t know what something, but I just said, ‘It’s happening.’ Something is happening.”
“So you can confirm that something is happening?” Colbert queried, to which the actor replied, “Something is happening. But we don’t know what that something is.”
“Doesn’t matter,” Stephen noted. “Something is better than nothing.”
PHOTO: NETLFIX
Interestingly, the rest of the Friends cast and creators have been adamant about the fact that they’re not remaking the super hit 90s sitcom. But when DeGeneres asked about it, Aniston had said, “Like a reboot of the show? No. Listen, we would love for there to be something, but we don’t know what that something is. So we’re just trying. We’re working on something.”
Friends aired from 1994 until 2004, starring Aniston as Rachel Green, Courteney Cox as Monica Geller, Matthew Perry as Chandler Bing, David Schwimmer as Ross Geller, Matt LeBlanc as Joey Tribbiani and Lisa Kudrow as Phoebe Buffay.

SputnikVM is an implementation of an Ethereum Virtual Machine. It aims to be an efficient, pluggable virtual machine for different Ethereum-based blockchains.
We encourage all Ethereum'esque blockchains to adopt SputnikVM, and to make use of SputnikVM's RFC governance project which governs the parameters of each blockchain's VM. This way we can draw from the experience of the community and learn from other proposed RFCs.
Features
- Standalone - can be launched as an independent process or integrated into other apps
- Universal - supports different Ethereum chains, such as ETC, ETH or private ones
- Stateless - only an execution environment connected to independent State storage
- Fast - main focus is on performance
- IoT compatible - designed to support hardware used in embedded devices
- FFI, Protobuf and JSON interface
- written in Rust, can be used as a binary, cargo crate or shared library

Dependencies
Ensure you have at least rustc 1.16.0 (30cf806ef 2017-03-10)
. Rust 1.15.0 and
before is not supported.
Documentation
Build from sources
SputnikVM is written Rust. If you are not familiar with Rust please see the getting started guide.
Build
To start working with SputnikVM you'll need to install rustup, then you can do:
$ git clone git@github.com:ethereumproject/sputnikvm.git
$ cd sputnikvm
$ cargo build --release --all
Testing
We currently use two ways to test SputnikVM and ensure its execution aligns with other Ethereum Virtual Machine implementations:
- jsontests: This uses part of the Ethereum tests. Those tests currently does not have good coverage for system operation opcodes. Besides, some tests are incorrect so they are disabled.
- regtests: A complete regression tests is done on the Ethereum Classic mainnet from genesis block to block 4 million. Some of the previously failed tests are also integrated into Rust's test system. See wiki for how to reproduce the regression tests.

100 years after the Panama Pacific International Exposition
After the Panama Pacific International Exposition, a wave of solidarity provided great impetus for a culture of innovation
A place steeped in a rich history
Today,
San Francisco has become a magnent
a vivid emblem
We hung our work in bright spaces
For people to see our stories
We called them galleries.
There we could design a path.
A narrative.
Now this is our gallery
Where we share our content with the world.
To make space, we tile.
This removes narrative.
Not to mention It's been getting more and more
Flat
Let's try something new.
Because
Our content
deserves Space
To flourish.
To impact
To Touch
Welcome to the future.

| Enum | Description |
|---|---|
| ColumnState.State |
Columns move through various lifecycle states as identified by this
enum.
|
| PullResultSetReaderImpl.State |
The primary purpose of this loader, and the most complex to understand and maintain, is overflow handling.
| Row | a | b | c | d | e | f | g | h |
|---|---|---|---|---|---|---|---|---|
| n-2 | X | X | X | X | X | X | - | - |
| n-1 | X | X | X | X | - | - | ||
| n | X | ! | O | O | O |
The scenarios, identified by column names above, are:
At the time of overflow on row n:
As the overflow write proceeds:
At harvest time:
When starting the next batch:
Arrays are a different matter: each row can have many values associated with it. Consider an array of scalars. We have:
Row 0 Row 1 Row 2
0 1 2 3 4 5 6 7 8
[ [a b c] [d e f] | [g h i] ]
Here, the letters indicate values. The brackets show the overall vector
(outer brackets) and individual rows (inner brackets). The vertical line
shows where overflow occurred. The same rules as discussed earier still
apply, but we must consider both the row indexes and the array indexes.
Row 0 Row 1 Row 0
0 1 2 3 4 5 0 1 2
[ [a b c] [d e f] ] [ [g h i] ]
Further, we must consider lists: a column may consist of a list of
arrays. Or, a column may consist of an array of maps, one of which is
a list of arrays. So, the above reasoning must apply recursively down
the value tree.
As it turns out, there is a simple recursive algorithm, which is a simple extension of the reasoning for the top-level scalar case, that can handle arrays:
Consider the writers. Each writer corresponds to a single vector. Writers are grouped into logical tree nodes. Those in the root node write to (single, scalar) columns that are either top-level columns, or nested some level down in single-value (not array) tuples. Another tree level occurs in an array: the elements of the array use a different (faster-changing) index than the top (row-level) writers. Different arrays have different indexes: a row may have, say, four elements in array A, but 20 elements in array B.
Further, arrays can be singular (a repeated int, say) or for an entire tuple (a repeated map.) And, since Drill supports the full JSON model, in the most general case, there is a tree of array indexes that can be nested to an arbitrary level. (A row can have an array of maps which contains a column that is, itself, a list of repeated maps, a field of which is an array of ints.)
Writers handle this index tree via a tree of ColumnWriterIndex
objects, often specialized for various tasks.
Now we can get to the key concept in this section: how we update those indexes after an overflow. The top-level index reverts to zero. (We start writing the 0th row in the new look-ahead batch.) But, nested indexes (those for arrays) will start at some other position depending on the number elements already written in an overflow row. The number of such elements is determined by a top-down traversal of the tree (to determine the start offset of each array for the row.) Resetting the writer indexes is a bottom-up process: based on the number of elements in that array, the writer index is reset to match.
This flow is the opposite of the "normal" case in which a new batch is started top-down, with each index being reset to zero.

abstraction. In particular, we use the
single tuple model which works with a single batch. This model provides a
simple, uniform interface to work with columns and tuples (rows, maps),
and a simple way to work with arrays. This interface reduces the above
array algorithm to a simple set of recursive method calls.Copyright © 2021 The Apache Software Foundation. All rights reserved.

N3bn election largesse causes stir in PDP - The Nation Newspaper
by https://www.facebook.com/alao.h.joshuaSentry
The governorship elections in Kogi and Bayelsa states have come and gone, but the dust they raised may take some time to settle.
A N3 billion largesse a governor doled out to some influential members of the party in Abuja is causing a stir as some aggrieved party members are clamouring for sanctions against the recipients of the said sum.
Although it was difficult to know who got what, Sentry learnt that the errant party henchmen actually demanded for N6 billion to facilitate the victory of the party’s candidate but got N3 billion as advanced payment.
It was not clear at press time whether the governor in question would be willing to pay the outstanding sum with the party’s loss of the election or demand a refund of the sum already paid.
But it is more likely that the influential members would not get more than they have received even if they will not have to make a refund, because the governor who gave out the money is said to be peeved that the party’s National Working Committee has been “unduly quiet” about the results of the elections.

--- layout: algorithm permalink: /algorithms/clustering/kmeans algorithm: kmeansclustering is_algorithms: true ---
Explanation of K-Means Clustering :
K-Means is one of the simplest unsupervised learning algorithms that solves the clustering problem. It groups all the objects in such a way that objects in the same group (group is a cluster) are more similar (in some sense) to each other than to those in other groups. For example, assume you have an image with a red ball on the green grass. K-Means will split all pixels into two clusters. The first cluster will contain the pixels of the ball, the second cluster will contain the pixels of the grass.IRIS Dataset is a table that contains several features of iris flowers of 3 species. Species can be "Iris-setosa", "Iris-versicolor", and "Iris-virginica". Each flower contains 5 features: Petal Length, Petal Width, Sepal Length, Sepal Width, and Species.


Provides the "enrich" method to enrich list-like R objects with new, relevant components. The current version has methods for enriching objects of class 'family', 'link-glm', 'lm', 'glm' and 'betareg'. The resulting objects preserve their class, so all methods associated with them still apply. The package also provides the 'enriched_glm' function that has the same interface as 'glm' but results in objects of class 'enriched_glm'. In addition to the usual components in a ‘glm' object, ’enriched_glm' objects carry an object-specific simulate method and functions to compute the scores, the observed and expected information matrix, the first-order bias, as well as model densities, probabilities, and quantiles at arbitrary parameter values. The package can also be used to produce customizable source code templates for the structured implementation of methods to compute new components and enrich arbitrary objects.

THEN the baleful fiend its fire belched out,
and bright homes burned. The blaze stood high
all landsfolk frighting. No living thing
would that loathly one leave as aloft it flew.
Wide was the dragon's warring seen,
its fiendish fury far and near,
as the grim destroyer those Geatish people
hated and hounded. To hidden lair,
to its hoard it hastened at hint of dawn.
Folk of the land it had lapped in flame,
with bale and brand. In its barrow it trusted,
its battling and bulwarks: that boast was vain!
To Beowulf then the bale was told
quickly and truly: the king's own home,
of buildings the best, in brand-waves melted,
that gift-throne of Geats. To the good old man
sad in heart, 'twas heaviest sorrow.
The sage assumed that his sovran God
he had angered, breaking ancient law,
and embittered the Lord.
The folk's own fastness that fiery dragon
with flame had destroyed, and the stronghold all
washed by waves; but the warlike king,
prince of the Weders, plotted vengeance.
Warriors'-bulwark, he bade them work
all of iron — the earl's commander —
a war-shield wondrous: well he knew
that forest-wood against fire were worthless,
linden could aid not. — Atheling brave,
he was fated to finish this fleeting life, [footnote 1]
his days on earth, and the dragon with him,
though long it had watched o'er the wealth of the hoard! —
Shame he reckoned it, sharer-of-rings,
to follow the flyer-afar with a host,
a broad-flung band; nor the battle feared he,
nor deemed he dreadful the dragon's warring,
its vigor and valor: ventures desperate
he had passed a-plenty, and perils of war,
contest-crash, since, conqueror proud,
Hrothgar's hall he had wholly purged,
and in grapple had killed the kin of Grendel,
loathsome breed! Not least was that
of hand-to-hand fights where Hygelac fell,
when the ruler of Geats in rush of battle,
lord of his folk, in the Frisian land,
son of Hrethel, by sword-draughts died,
by brands down-beaten. Thence Beowulf fled
through strength of himself and his swimming power,
though alone, and his arms were laden with thirty
coats of mail, when he came to the sea!
Nor yet might Hetwaras [footnote 2] haughtily boast
their craft of contest, who carried against him
shields to the fight: but few escaped
from strife with the hero to seek their homes!
Then swam over ocean Ecgtheow's son
lonely and sorrowful, seeking his land,
where Hygd made him offer of hoard and realm,
rings and royal-seat, reckoning naught
the strength of her son to save their kingdom
from hostile hordes, after Hygelac's death.
No sooner for this could the stricken ones
in any wise move that atheling's mind
over young Heardred's head as lord
and ruler of all the realm to be:
yet the hero upheld him with helpful words,
aided in honor, till, older grown,
he wielded the Weder-Geats. — Wandering exiles
sought him o'er seas, the sons of Ohtere,
who had spurned the sway of the Scylfings'-helmet,
the bravest and best that broke the rings,
in Swedish land, of the sea-kings' line,
haughty hero. [footnote 3] Hence Heardred's end.
For shelter he gave them, sword-death came,
the blade's fell blow, to bairn of Hygelac;
but the son of Ongentheow sought again
house and home when Heardred fell,
leaving Beowulf lord of Geats
and gift-seat's master. — A good king he!

Thank you for visiting


React Project
You’ve spent the last two weeks on a whirlwind tour of React and some of its most popular features and libraries in its ecosystem. Now, you get to do something substantial with it while its fresh in your minds.
Next week, you get a full week to write a compelling front-end application to go into your portfolio. It should be something that you can display to demonstrate the skills that you’ve picked up over the past two weeks. While you do have to use React, the rest is up to you, but we recommend that you use Hooks in your project because those are the latest way that people build things in React and will be most appealing to people that are looking at your project.
Because this is an individual project, you have full freedom (and ultimately responsibility) of being able to get something done. If you want to build the entire fullstack application yourself, that’s great! Just make sure you scope the amount of work into something that you feel is best for your week’s worth of time. Use your newly-found knowledge of how long it took you to build your other project to determine how much you could get done on your own.
If you choose not to build a full-stack project, but just want to spend all of your time on the front-end, consider building a front-end for any of the group projects, it doesn’t have to be your own. Or, you can check out Programmable Web which lists thousands of APIs that you can use in your project.
Now that you have an understanding of how Websockets work, use the socket.io library on your backend to make Websocket development easy.
Moreover, search for third-party React libraries that you can use to help speed your development or give your application a polished look. Here are some suggestions for you to look at as a start:
- Grommet: A react-based framework that provides accessibility, modularity, responsiveness, and theming in a tidy package
- Material UI: A library of components that adhere to the Material design specifications
- React Bootstrap: A library of React components that wrap Bootstrap
- Semantic UI React: A development framework that helps create beautiful, responsive layouts using human-friendly HTML.
Those are just starting points. You can look for more by using your favorite search engine and terms like “react libraries”.
Homework
Think about what you’d like to do, poke around Programmable Web, go back and look at all of the group projects, look at the list of projects at the end of this article. Find something that you would like to do. You already have a strong knowledge of how to build a data API. You have the code to hook in authentication using JWTs. You can reuse your models and migrations from earlier projects.
Planning Day
Put together your proposal. In software development, normally, a week of planning can give you about three months of work. So, your day of figuring out what you’d like your app to do should give you a week
Project ideas
Here is that list of project suggestions, again, with their different requirements. Feel free to do one of them, if you think you have time.
