Yes. Finally I’ve got an arduino board. It’s time to hack a little bit. Today I want to try different things. I want to display in a webpage one value from my arduino board. For example one analog data using a potentiometer. Let’s start.
We are going to use one potentiometer. A potentiometer is a resistor with a rotating contact that forms an adjustable voltage divider. It has three pins. If we connect one pin to 5V power source of our arduino, another one to the ground and another to one A0 (analog input 0), we can read different values depending on the position of potentiometer’s rotating contact.
Arduino has 10 bit analog resolution. That means 1024 possible values, from 0 to 1023. So when our potentiometer gives us 5 volts we’ll obtain 1024 and when our it gives us 0V we’ll read 0. Here we can see a simple arduino program to read this analog input and send data via serial port:
int mem;
void setup() {
Serial.begin(9600);
}
void loop() {
int value = analogRead(A0);
if (value != mem) {
Serial.println(value);
}
mem = value;
delay(100);
}
This program is simple loop with a delay of 100 milliseconds that reads A0 and if value is different than previously read (to avoid sending the same value when nobody is touching the potentiometer) we send the value via serial port (with 9600 bauds)
We can test our program using the serial monitor of our arduino IDE our using another serial monitor.
Now we’re going to create one script to read this serial port data. We’re going to use Python. I’ll use my laptop and my serial port is /dev/tty.usbmodem14231
import serial
arduino = serial.Serial('/dev/tty.usbmodem14231', 9600)
while 1:
print arduino.readline().strip()
Basically we’ve got our backend running. Now we can create a simple frontend.
...

...
We’ll need websockets. I normally use socket.io but today I’ll use Crossbar.io. Since I hear about it in a Ronny’s talk at deSymfony conference I wanted to use it.
I’ll change a little bit our backend to emit one event
import serial
from os import environ
from twisted.internet.defer import inlineCallbacks
from twisted.internet.task import LoopingCall
from autobahn.twisted.wamp import ApplicationSession, ApplicationRunner
arduino = serial.Serial('/dev/tty.usbmodem14231', 9600)
class SeriaReader(ApplicationSession):
@inlineCallbacks
def onJoin(self, details):
def publish():
return self.publish(u'iot.serial.reader', arduino.readline().strip())
yield LoopingCall(publish).start(0.1)
if __name__ == '__main__':
runner = ApplicationRunner(environ.get("GONZALO_ROUTER", u"ws://<IP_ADDRESS>:8080/ws"), u"iot")
runner.run(SeriaReader)
Now I only need to create a crossbar.io server. I will use node to do it
var autobahn = require('autobahn'),
connection = new autobahn.Connection({
url: 'ws://<IP_ADDRESS>:8080/ws',
realm: 'iot'
}
);
connection.open();
And now we only need to connect our frontend to the websocket server
$(function () {
var connection = new autobahn.Connection({
url: "ws://<IP_ADDRESS>:8080/ws",
realm: "iot"
});
connection.onopen = function (session) {
session.subscribe('iot.serial.reader', function (args) {
$('#display').html(args[0]);
});
};
connection.open();
});
It works but thre’s a problem. The first time we connect with our browser we won’t see the display value until we change the position of the potentiometer. That’s because ‘iot.serial.reader’ event is only emitted when potentiometer changes. No change means no new value. To solve this problem we only need to change a little bit our crossbar.io server. We’ll “memorize” the last value and we’ll expose one method ‘iot.serial.get’ to ask about this value
var autobahn = require('autobahn'),
connection = new autobahn.Connection({
url: 'ws://<IP_ADDRESS>:8080/ws',
realm: 'iot'
}
),
mem;
connection.onopen = function (session) {
session.register('iot.serial.get', function () {
return mem;
});
session.subscribe('iot.serial.reader', function (args) {
mem = args[0];
});
};
connection.open();
An now in the frontend we ask for ‘iot.serial.get’ when we connect to the socket
$(function () {
var connection = new autobahn.Connection({
url: "ws://<IP_ADDRESS>:8080/ws",
realm: "iot"
});
connection.onopen = function (session) {
session.subscribe('iot.serial.reader', function (args) {
$('#display').html(args[0]);
}).then(function () {
session.call('iot.serial.get').then(
function (result) {
$('#display').htmlresult);
}
);
}
);
};
connection.open();
});
And thats all. The source code is available in my github account. You also can see a demo of the working prototype here


Html is the main type of document/content on the web. When a person uses his or her browser to go to a webpage, that webpage is sending a HTTP request to a server. That server in turn finds the HTML doc and sends it back to the user's browser. The web browser then interprets this HTML.
HTMLHTML stands for Hyptertext Markup Language.HTML is made up of text content, which is what you see, and mark up, which is what that content looks like.
Tags and ElementsHTML is made up of elements. Tags are then used to define these elements. An attribute is an element modifier. The anchor attribute is utilized to form links within elements.
Block and Inline: What's the difference?Inline tags differ from block tags because block tags form an invisible box around the content inside of them.

Mohamed Salah, Sadio Mane and Pierre-Emerick Aubameyang Among 30 African Player of the Year Nominees
by Robbie CopelandPremier League golden boot winners Mohamed Salah, Sadio Mane and Pierre-Emerick Aubameyang are among the 30 nominees for the prestigious 2019 African Player of the Year award.
The trio headline the shortlist after they each netted 22 goals in the 2018/19 season, ensuring the top-scorer award would be split for the first time since the 2010-11 season - and the first time since 1999 it would be split three ways.
Aubameyang has started the 2019/20 campaign with eight goals in 13 appearances for the Gunners, while 21 goals between the Liverpool duo put each in with a strong chance of lifting the award, currently held by Salah.
The Anfield pair join teammate Naby Keita, who makes the cut despite a difficult start to life in England, while Aubameyang has an Arsenal teammate in Nicolas Pepe, whose goalscoring heroics with Lille earned him a £72m move to the Premier League.
Manchester City's Riyad Mahrez, Leicester's Wilfried Ndidi, Aston Villa's Trezeguet and Crystal Palace duo Wilfried Zaha and Jordan Ayew round out the Premier League representation, while French champions PSG have two nominees in Idrissa Gueye and Eric Maxim Choupo-Moting.
Ajax keeper Andre Onana continues his steady rise to the top with a place on the shortlist, as does domestic teammate Hakim Ziyech, while Atletico's Thomas Partey is the sole representative from La Liga.
Below is the entire list of nominees for the award, which will be handed on on 7th January 2020, at the CAF's award ceremony in Hurghada, Egypt.
| Achraf Hakimi (Borussia Dortmund) | Andre Onana (Ajax) |
| Baghdad Bounedjah (Al-Sadd) | Carlous Andriamatsinoro (Al-Adalah) |
| Eric Maxim Choupo-Moting (PSG) | Denis Onyango (Mamelodi Sundowns) |
| Ferjani Sassi (Zamalek) | Kodjo Fo Doh Laba (Al Ain) |
| Hakim Ziyech (Ajax) | Idrissa Gueye (PSG) |
| Ismail Bennacer (AC Milan) | Jordan Ayew (Crystal Palace) |
| Kalidou Koulibaly (Napoli) | Trezeguet (Aston Villa) |
| Mbwana Samatta (Genk) | Mohamed Salah (Liverpool) |
| Moussa Marega (Porto) | Naby Keita (Liverpool) |
| Nicolas Pepe (Arsenal) | Odion Ighalo (Shanghai Shenhua) |
| Percy Tau (Club Brugge) | Pierre-Emerick Aubameyang (Arsenal) |
| Riyad Mahrez (Manchester City) | Sadio Mane (Liverpool) |
| Taha Yassine Khenissi (ES de Tunis) | Thomas Partey (Atletico Madrid) |
| Victor Osmihen (Lille) | Wilfried Ndidi (Leicester) |

When I say Vietnamese food, what’s the first thing popping into your mind? Phở? 🙂 Originated from northern Vietnam in the early 20th century, this delicious noodle soup has been popularized in other parts of the world by refugees after the Vietnam War.
Well, Vietnamese people might laugt at it, since they surely have so much more to offer than this little bowl of noodle soup. But after trying out different food around Vietnam, I have to say phở is still one of my favorites. 😄
##
Here I’m sharing some photos of the Phở bò (beef noodle soup) I had in Hanoi, the country’s capital. Since my friend Joy is traveling there right now and we talked about the local food.
Phở consists of beef or chicken broth, herbs, and rice noodles called bánh phở. Phở bò is with beef cuts and Phở gà has chicken in it. When I was in Hanoi, I ate it almost any time of the day, but when I went to the south of Vietnam, it’s more difficult to find it after breakfast time. The size of the rice noodles, the choice of herbs and the taste of the broth are also different.

因为老朋友Joy正在越南的首都河内游玩，问我以前在那吃了啥好吃的，我在手机里一通搜索，找到些河内逛吃的照片，这次先来分享个越南有名的河粉。
20世纪早期，越南河粉起源于国家的北部，也就是河内所在的那块地区。越南战争后被难民带到世界各地，广受欢迎。西方国家大城市的街头也常常能看到卖越南河粉的店。
当然，如果我们一提越南菜就说河粉，越南人估计会发笑，因为毕竟还有那么多其他美食呢。然鹅，我从北到南吃了一圈各种菜，还是觉得河粉最合胃口，哈哈…… 我这是烂泥扶不上墙的刘阿斗吗？😄
一般越南河粉有鸡肉和牛肉两种口味，北方和南方用的米粉宽度、汤头味道和香草🌿配料也有不同。我这里发的是在北方的河内一家小店吃到的牛肉河粉。在河内和其他北方地区时，一天到晚街头都有河粉卖，但后来到了南部，过了吃早餐的时间，就很难找到河粉摊子了。

A Mother Duck and Her Chicks Bring Springtime Smith Street Traffic to a Standstill
Why did the duck cross the road? No one knows, but if you see her, give her some breathing room.
by Callum McDermottTrams may not stop for you and me, but in the face of overwhelming cuteness, even those vehicles will relent. And in Fitzroy this afternoon, relent they did, when a duck and her 10 tiny chicks crossing Smith Street brought traffic to a standstill.
A crowd soon gathered, phones ripped out of pockets, Insta-stories taken. Broadsheet was on the scene as the fowl and her brood began their procession east down Stanley Street.
“Don’t get too close to them,” shouts a concerned bystander to the assembled camera crew. Duck safety was paramount. “They need to be kept off the road,” warns another.
But the mother duck and her young family were blissfully unaware of the human squabbles going on around them.
The rest of the crowd tries to corral the ducks next to Collingwood cafe Proud Mary, then someone calls Wildlife Victoria and takes command of the situation.
“Ok, I’ve just spoken with Wildlife services, we need to stay away from the duck,” she said with gravitas. “The mother may get spooked and she will fly away, abandoning the chicks.”
According to the Wildlife Victoria website, it’s common for mother ducks to be on the move during spring. They often hatch their babies in suburban gardens and can walk with baby ducks for up to two days to nearby parks, creeks and natural reserves in search of food and water.
So, the group leaves the brave young duck mum and her chicks to continue unhindered. They knew where they were going. They may have waddled away from us, but they’ve waddled into our hearts.
If you spot the Fitzroy-Collingwood mother duck and her brood, or any other young duck families, Wildlife Victoria advises that in most situations they do not need to be rescued and should be left alone and allowed to go on their way. More information can be found here.

Is cloud computing actually worth it?
By Arthur Felipe
July 12, 2021
SUMMARY: In the IT field, there are many strong opinions for and against cloud computing. But what is the fuss all about? Is it actually worth it? Are some better than others?
If you open a YouTube video that even touches the subject of cloud computing, you will
find people on the comments section typing either A) Cloud is the worst thing ever created
or B) Cloud is magical. Reality check: It isn't either. Why?
In the past, cloud resources were a complicated type of business, since subscription-based
plans only gained credibility in the last couple of years (mainly because of streaming services
like Netflix, Hulu, Spotify and many others). The fear of being overcharged or having your
information leaked was very strong, and it was justified.
DATA BREACHING AND OVERCHARGING
There are 2 main ways where your data could be exposed when working with cloud computing: Your
sensitive data being leaked (like credit card info, personal or company data, and so on) because
of weak digital security practices, or, content regarding your project being leaked (like databases
and such), since you are trusting your sensitive data to another company. As time went on, new
security measurements were implemented (look around, we don't even mind looking up the site' security
certificates we are buying things from). This, in pair with the fact that most of the cloud resources
are generally offered by well-known and well-trusted tech companies (like Google, Microsoft and Amazon)
keeps bringing more assurance to people their data is actually secure (from malicious users, because
these companies WILL use your data how and whenever they want to, as described in their TOSs). On top
of that, these platforms also offer you, the developer, a bunch of counter measurements against DDoS
& OWASP that, in the end, if well set up, should back you up against plenty of attacks (cloud-specific
or even general web attacks, what is a very solid argument for these services). Platforms like Google's
GCP also feature load-balancing, security policies, real time monitoring and many other features, just
like your traditional server setup, usually with no extra charges.
Overcharging is also a big concern when we talk about cloud computing. We have all heard companies
that made one silly mistake which cost them upwards of 20 THOUSAND dollars. And you also have normal,
everyday users that slipped their fingers and sent 1 thousand bucks down the drain in a couple of hours.
The most common counter measurement is to set a spend limit (which, as far as I know Google offers and
insists that you use it in their course). You can also set usage limits, so you don't exceed your quota.
On top of that, some companies don't want to be the "bad guys": Google doesn't want you to spend 5 grand
by mistake, keep it and then risk their own image or stock prices. That may vary a lot, since you will
be relying solely on the company' mercy and customer relationship policy. My tip for you? Don't rely on
that. Keep a very tight spending quota, so if things go south, you and your company are both safe.
EASE OF USE AND RESOURCES
Working with either locally hosted servers or cloud hosted servers requires some knowledge, especially if you are, for example, dealing with an important website, known to have many visitors around the world, and should have >99% of availability. My biggest experience is with Google's GCP, and as far as I can tell, the UI is very straight-forward, documentation is VERY well done and there are plenty of courses! Google even offers you plenty of hands-on experience with their courses, which I absolutely recommend (and this post is not sponsored by any means, I just dig the service a bunch). I've had more problems with AWS, but that's out of the scope.
PRICING
That's the fun part. If you have big needs, to host a local server, you have to consider:
And the costs only go up. I have no doubts that the expense, plus the inconvenience of hosting your
own server is enough to make you move to a cloud hosted service. Don't get me wrong, it is still going
to be expensive, but less.
For small businesses, I also recommend cloud-based alternatives, since there are very low-buck options
that are more than capable of dealing with the load, and the AVAILABILITY and RELIABILITY are just
unbeatable (for the price, at least). Way better than using a 7y.o. dual core as a makeshift server.
But, if you have a medium-sized business that can get by with a core i7 or i9, I really recommend
sticking to the locally hosted server (if you can deal with downtime in some way). Why? In this tier,
cloud hosting prices are actually quite high, to the point that, in the long run, it's cheaper to
have your own solution. On top of that, a core i7 or i9 server is still quite small and isn't much
of a hassle. Of course, you will have to come up with your own solution regarding attacks and updates,
but that's on you to decide. Also, you have to consider your company's growth: Does your company have
the chance of, in the near future, becoming a big company, with big needs? If yes, maybe you should
consider a cloud-based solution from the very beginning, so you don't have to spend money twice
(buying a decent local server and then after a couple of years having to rent a web server is no
good). That's why it is so important to know your business and plan every spend with caution.
Don't rely on a guy on the internet, real data is unbeatable.
I hope you guys have enjoyed all this! I'm a Systems Information Undergraduate that enjoys computing in general and want
to give my view on this topic :)

15 cool startups you didn’t know were on Amazon
by Connie Chen, Business Insider US- For a long time, if you wanted to find your favorite startup anywhere outside of its own website, you were out of luck.
- Slowly, they’re beginning to join online retailers like Target and Nordstrom to make it easier for you to find and shop their innovative products.
- Amazon is another popular choice. It’s the most far-reaching and convenient platform for you to buy nearly anything you want.
- So if cool new mattresses, bedding and bath products, clothing, and accessories are on your list, go ahead and shop the following 15 startups on Amazon.

As startups begin to look beyond their own websites and diversify their selling options, some choose Target as their main traditional retailer, while others flock to Nordstrom, all in hopes of attracting a very specific type of customer.
But the pure reach, convenience, and customer service army of Amazon make it the obvious choice for many startups. Some companies, like Casper, are actually available on all three shopping sites, in addition to its own, an aggressive strategy that surely improves its brand exposure.
Starting off on Amazon is a great stepping stone to more exposure and customers because the majority of online shoppers are already on Amazon. If they can shop interesting new products alongside the familiar brands and supplies they’re buying anyway, they will.
It also helps that most of these startup products are available with Prime shipping, allowing them to bypass slower shipping speeds offered elsewhere.
If you need to update your personal care routine, mattress, or closet, these 15 startups on Amazon have you covered.

Lactuca spp.
I want to start off this report with a quote. 'To fear it, is to repect it.' I fear all herbs and I am cautious about them all.
Mind set: A little stressed from the day and excited about my prospect of finding a local herb shop and the thoughts of a continued supply of herbs to experiment with.
Time frame: it was at 22:00, I got done eating 4 slices of pizzahut and a chaser of cranberry juice. And watching Iron Monkey and chatting online with my sister.
Preparation: I removed all the stems from herb and hand crushed it so I can better use it with zigzags (I also always use filters).
1.Smoke: during the first joint I noticed that the smoke was thicker then what I'm use to and I was amazed that I was able to completely inhale it without difficulty *is it possible the herb has a numbing effect to the throat?*.
1.Effects: no noticeable effects except the possible numbness of the throat. I expected the filter and saw that is was dark brown... Much darker then a cig filter after use.
2. Smoke: the second joint held some effects. A very slight body numbness and a tingling feeling around the face (feels like it was coming from the third eye). A slight desire to lay down. But complete control of the body and mind was still there. The effects lasted for 10 minutes and afterwards I continued on in my normal night life (but for safety's sake I refrain from drinking and using other herbs and drugs that night). I went to sleep and stayed a sleep until my alarm clock woked me (normally I'll wake up a few times before my wake up call).

K-Nearest Neighbors (k-NN)
- KNN:
KNN is a non-parametric method used for classification and regression.
It is based on the Local Constancy (Smoothness) Prior, which states that “the function we learn should not change very much within a small region.”, for generalization. - Structure:
In both classification and regression, the input consists of the \(k\) closest training examples in the feature space. The output depends on whether k-NN is used for classification or regression:- In k-NN classification, the output is a class membership. An object is classified by a plurality vote of its neighbors, with the object being assigned to the class most common among its \(k\) nearest neighbors (\(k\) is a positive integer, typically small). If \(k = 1\), then the object is simply assigned to the class of that single nearest neighbor.
- In k-NN regression, the output is the property value for the object. This value is the average of the values of \(k\) nearest neighbors.
-
Formal Description - Statistical Setting:
Suppose we have pairs \({\displaystyle (X_{1},Y_{1}),(X_{2},Y_{2}),\dots ,(X_{n},Y_{n})}\) taking values in \({\displaystyle \mathbb {R} ^{d}\times \{1,2\}}\), where \(Y\) is the class label of \(X\), so that \({\displaystyle X|Y=r\sim P_{r}}\) for \({\displaystyle r=1,2}\) (and probability distributions \({\displaystyle P_{r}}\). Given some norm \({\displaystyle \|\cdot \|}\) on \({\displaystyle \mathbb {R} ^{d}}\) and a point \({\displaystyle x\in \mathbb {R} ^{d}}\), let \({\displaystyle (X_{(1)},Y_{(1)}),\dots ,(X_{(n)},Y_{(n)})}\) be a reordering of the training data such that \({\displaystyle \|X_{(1)}-x\|\leq \dots \leq \|X_{(n)}-x\|}\).
-
Choosing \(k\):
Nearest neighbors can produce very complex decision functions, and its behavior is highly dependent on the choice of \(k\):
Choosing \(k = 1\), we achieve an optimal training error of \(0\) because each training point will classify as itself, thus achieving \(100\%\) accuracy on itself.
However, \(k = 1\) overfits to the training data, and is a terrible choice in the context of the bias-variance tradeoff.Increasing \(k\) leads to increase in training error, but a decrease in testing error and achieves better generalization.
At one point, if \(k\) becomes too large, the algorithm will underfit the training data, and suffer from huge bias.
In general, we select \(k\) using cross-validation.
- \[\text{Training and Test Errors as a function of } k \:\:\:\:\:\:\:\:\:\:\:\:\]
- Bias-Variance Decomposition of k-NN:
- Properties:
- Computational Complexity:
- We require \(\mathcal{O}(n)\) space to store a training set of size \(n\). There is no runtime cost during training if we do not use specialized data structures to store the data.
However, predictions take \(\mathcal{O}(n)\) time, which is costly. - There has been research into Approximate Nearest Neighbors (ANN) procedures that quickly find an approximation for the nearest neighbor - some common ANN methods are Locality-Sensitive Hashing and algorithms that perform dimensionality reduction via randomized (Johnson-Lindenstrauss) distance-preserving projections.
- k-NN is a type of instance-based learning, or “lazy learning”, where the function is only approximated locally and all computation is deferred until classification.
- We require \(\mathcal{O}(n)\) space to store a training set of size \(n\). There is no runtime cost during training if we do not use specialized data structures to store the data.
- Flexibility:
- When \(k>1,\) k-NN can be modified to output predicted probabilities \(P(Y \vert X)\) by defining \(P(Y \vert X)\) as the proportion of nearest neighbors to \(X\) in the training set that have class \(Y\).
- k-NN can also be adapted for regression — instead of taking the majority vote, take the average of the \(y\) values for the nearest neighbors.
- k-NN can learn very complicated, non-linear decision boundaries (highly influenced by choice of \(k\)).
- Non-Parametric(ity):
k-NN is a non-parametric method, which means that the number of parameters in the model grows with \(n\), the number of training points. This is as opposed to parametric methods, for which the number of parameters is independent of \(n\). - High-dimensional Behavior:
- k-NN does NOT behave well in high dimensions.
As the dimension increases, data points drift farther apart, so even the nearest neighbor to a point will tend to be very far away. - It is sensitive to the local structure of the data (in any/all dimension/s).
- k-NN does NOT behave well in high dimensions.
- Theoretical Guarantees/Properties:
\(1\)-NN has impressive theoretical guarantees for such a simple method:- Cover and Hart, 1967 prove that as the number of training samples \(n\) approaches infinity, the expected prediction error for \(1-\mathrm{NN}\) is upper bounded by \(2 \epsilon^{*}\), where \(\epsilon^{*}\) is the Bayes (optimal) error.
- Fix and Hodges, 1951 prove that as \(n\) and \(k\) approach infinity and if \(\frac{k}{n} \rightarrow 0\), then the \(k\) nearest neighbor error approaches the Bayes error.
- Computational Complexity:
- Algorithm and Computational Complexity:
Training:- Algorithm: To train this classifier, we simply store our training data for future reference.
Sometimes we store the data in a specialized structure called a k-d tree. This data structure usually allows for faster (average-case \(\mathcal{O}(\log n)\)) nearest neighbors queries.For this reason, k-NN is sometimes referred to as “lazy learning”.
- Complexity: \(\:\:\:\:\mathcal{O}(1)\)
Prediction:
- Algorithm:
- Compute the \(k\) closest training data points (“nearest neighbors”) to input point \(\boldsymbol{z}\).
“Closeness” is quantified using some metric; e.g. Euclidean distance. - Assignment Stage:
- Classification: Find the most common class \(y\) among these \(k\) neighbors and classify \(\boldsymbol{z}\) as \(y\) (majority vote)
- Regression: Take the average label of the \(k\) nearest points.
- Compute the \(k\) closest training data points (“nearest neighbors”) to input point \(\boldsymbol{z}\).
- Complexity: \(\:\:\:\:\mathcal{O}(N)\)
Notes:
- We choose odd \(k\) for binary classification to break symmetry of majority vote
- Algorithm: To train this classifier, we simply store our training data for future reference.
-
Behavior in High-Dimensional Space - Curse of Dimensionality:
As mentioned, k-NN does NOT perform well in high-dimensional space. This is due to the “Curse of Dimensionality”.Curse of Dimensionality (CoD):
To understand CoD, we first need to understand the properties of metric spaces. In high-dimensional spaces, much of our low-dimensional intuition breaks down:Geometry of High-Dimensional Space:
Consider a ball in \(\mathbb{R}^d\) centered at the origin with radius \(r\), and suppose we have another ball of radius \(r - \epsilon\) centered at the origin. In low dimensions, we can visually see that much of the volume of the outer ball is also in the inner ball.
In general, the volume of the outer ball is proportional to \(r^{d}\), while the volume of the inner ball is proportional to \((r-\epsilon)^{d}\).
Thus the ratio of the volume of the inner ball to that of the outer ball is:$$\frac{(r-\epsilon)^{d}}{r^{d}}=\left(1-\frac{\epsilon}{r}\right)^{d} \approx e^{-\epsilon d / r} \underset{d \rightarrow \infty}{\longrightarrow} 0$$
Hence as \(d\) gets large, most of the volume of the outer ball is concentrated in the annular region \(\{x : r-\epsilon < x < r\}\) instead of the inner ball.
Concentration of Measure:
High dimensions also make Gaussian distributions behave counter-intuitively. Suppose \(X \sim\) \(\mathcal{N}\left(0, \sigma^{2} I\right)\). If \(X_{i}\) are the components of \(X\) and \(R\) is the distance from \(X\) to the origin, then \(R^{2}=\sum_{i=1}^{d} X_{i}^{2}\). We have \(\mathbb{E}\left[R^{2}\right]=d \sigma^{2},\) so in expectation a random Gaussian will actually be reasonably far from the origin. If \(\sigma=1,\) then \(R^{2}\) is distributed chi-squared with \(d\) degrees of freedom.
One can show that in high dimensions, with high probability \(1-\mathcal{O}\left(e^{-d^{\epsilon}}\right)\), this multivariate Gaussian will lie within the annular region \(\left\{X :\left|R^{2}-\mathbb{E}\left[R^{2}\right]\right| \leq d^{1 / 2+\epsilon}\right\}\) where \(\mathbb{E}\left[R^{2}\right]=d \sigma^{2}\) (one possible approach is to note that as \(d \rightarrow \infty,\) the chi-squared approaches a Gaussian by the CLT, and use a Chernoff bound to show exponential decay). This phenomenon is known as Concentration of Measure.Without resorting to more complicated inequalities, we can show a simple, weaker result:
\(\bf{\text{Theorem:}}\) \(\text{If } X_{i} \sim \mathcal{N}\left(0, \sigma^{2}\right), i=1, \ldots, d \text{ are independent and } R^{2}=\sum_{i=1}^{d} X_{i}^{2}, \text{ then for every } \epsilon>0, \\ \text{the following holds: }\)$$\lim_{d \rightarrow \infty} P\left(\left|R^{2}-\mathbb{E}\left[R^{2}\right]\right| \geq d^{\frac{1}{2}+\epsilon}\right)=0$$
Thus in the limit, the squared radius is concentrated about its mean.
Thus a random Gaussian will lie within a thin annular region away from the origin in high dimensions with high probability, even though the mode of the Gaussian bell curve is at the origin. This illustrates the phenomenon in high dimensions where random data is spread very far apart.
The k-NN classifier was conceived on the principle that nearby points should be of the same class - however, in high dimensions, even the nearest neighbors that we have to a random test point will tend to be far away, so this principle is no longer useful.
-
Improving k-NN:
(1) Obtain More Training Data:
More training data allows us to counter-act the sparsity in high-dimensional space.(2) Dimensionality Reduction - Feature Selection and Feature Projection:
Reduce the dimensionality of the features and/or pick better features. The best way to counteract the curse of dimensionality.(3) Different Choices of Metrics/Distance Functions:
We can modify the distance function. E.g.- The family of Minkowski Distances that are induced by the \(L^p\) norms:
$$D_{p}(\mathbf{x}, \mathbf{z})=\left(\sum_{i=1}^{d}\left|x_{i}-z_{i}\right|^{p}\right)^{\frac{1}{p}}$$
Without preprocessing the data, \(1-\mathrm{NN}\) with the \(L^{3}\) distance outperforms \(1-\mathrm{NN}\) with \(L^{2}\) on MNIST.
- We can, also, use kernels to compute distances in a different feature space.
For example, if \(k\) is a kernel with associated feature map \(\Phi\) and we want to compute the Euclidean distance from \(\Phi(x)\) to \(\Phi(z)\), then we have:$$\begin{aligned}\|\Phi(\mathbf{x})-\Phi(\mathbf{z})\|_ {2}^{2} &=\Phi(\mathbf{x})^{\top} \Phi(\mathbf{x})-2 \Phi(\mathbf{x})^{\top} \Phi(\mathbf{z})+\Phi(\mathbf{z})^{\top} \Phi(\mathbf{z}) \\ &=k(\mathbf{x}, \mathbf{x})-2 k(\mathbf{x}, \mathbf{z})+k(\mathbf{z}, \mathbf{z}) \end{aligned}$$
Thus if we define \(D(\mathrm{x}, \mathrm{z})=\sqrt{k(\mathrm{x}, \mathrm{x})-2 k(\mathrm{x}, \mathrm{z})+k(\mathrm{z}, \mathrm{z})}\) , then we can perform Euclidean nearest neighbors in \(\mathrm{\Phi}\)-space without explicitly representing \(\Phi\) by using the kernelized distance function \(D\).

pkg-info-srv
pkg-info-srv is a Proof Of Concept for a service that would provide information on GNU/Linux packages.
The problem
The initial requirements are pasted verbatim below
View Packages
On a Debian or an Ubuntu system there is a file called /var/lib/dpkg/status that holds information about software packages that the system knows about. Write a small program in Typescript that exposes some key information about currently installed packages via a REST API. The program should listen to HTTP requests on port 8080 on localhost and provide the following features:
1. The root API endpoint for the packages `/api/packages/` lists installed packages alphabetically and allows the consumer to find the details (2.) for each package.
2. Each package has its own API endpoint for details `/api/packages/:package-name`, the following information should be returned:
- Name
- Description
- The names of the packages the current package depends on (skip version numbers)
- The names of the packages that depend on the current package
Some things to keep in mind:
- Use REST/HATEOAS conventions.
- Minimize the use of external dependencies.
- The goal of the assignment is to view how you solve the problems with the programming language, not how well you use package managers :)
- The main design goal of this program is maintainability.
- Only look at the Depends field. Ignore other fields that work similarly, such as Suggests and Recommends.
- The section Syntax of control files of the Debian Policy Manual applies to the input data.
- A sample input file from https://gist.github.com/lauripiispanen/29735158335170c27297422a22b48caa
- Please avoid making your submission available to potential third parties by posting it to a public repository. Using a private repository is fine, or alternatively you can submit a zip file of the repository.
Addendum
-
The requirement of the solution being written in Typescript was deemed a recommendation from the client. If any other framework/approach is implemented, a justification ensues.
-
The service should listen to the file changes (i.e.: the file can be considered dynamic, thus the service needs to react to file changes and serve the updated information accordingly.
A solution
A solution for the given problem is to implement a REST service that listens for requests to the given endpoints (/api/packages/
and /api/packages/:package-name
) and provides the required response defined above in detail. The response payload is returned in JSON format.
The service reads the given file that describes packages installed in GNU/Linux Debian/Ubuntu systems, interprets it and responds with the required information in JSON format. The responses will contain, along with the payload, a status code conforming the standard HTTP status codes commonly used in REST architecture (2xx success, 4xx client error, etc). The server will respond with a 404 status code to other endpoints other than the mentioned above aside from documentation-related endpoints listed in OpenApi definition in root URL.
The service is to be implemented in Ruby using Sinatra.
For more information, refer to the TODO.
A justification
TBD
Usage
Given a successful installation of Ruby on local machine run through the following steps:
-
Checkout codez
-
$ bundle install
-
$ bundle exec rackup -p 8080
-
Open browser and point it to localhost:8080
or with Docker (upon request)
$ docker run -it -p 8080:8080 spavi/pkg-info-srv:latest
Rake has been taken into use for automating some tasks (documentation, code analysis). For a list of automated tasks:
$ bundle exec rake -vT
rake doc:yard # Generate YARD Documentation
rake rubocop # Run RuboCop
rake rubocop:auto_correct # Auto-correct RuboCop offenses
rake spec # Run RSpec code examples
Documentation
Use rake
to generate the documentation.
$ bundle exec rake doc:yard # To re-generate documentation
Documentation is generated to ./doc folder. You can mount it using Docker and ecstatic:
docker run -d --name docserver -p 80:80 -v ~/Documents/workbench/pkg-info-srv/doc:/var/html/www magandrez/ecstatic
Tests
Tests are written using RSpec. Use rake
to run tests.

Analysis of dichotomous and polytomous response data using
unidimensional and multidimensional latent trait models under the Item
Response Theory paradigm (Chalmers (2012) <doi:10.18637/jss.v048.i06>).
Exploratory and confirmatory models can be estimated with quadrature (EM)
or stochastic (MHRM) methods. Confirmatory
bi-factor and two-tier analyses are available for modeling item testlets.
Multiple group analysis and mixed effects designs also are available for
detecting differential item and test functioning as well as modeling
item and person covariates. Finally, latent class models such as the DINA,
DINO, multidimensional latent class, and several other discrete latent
variable models, including mixture and zero-inflated response models,
are supported.

The above example will create the FIFE II project and set the project_id, full_name, description, etc. it will also add any xlinks that contain 220
to the FIFE_2 project.
- Set NetCDF dataset metadata: Open dataset and replace "???" with the appropriate information. The template will use the project AOI and TOI
for the dataset.
dataset_id="145.001"
name="Navigation, State Parameter, and Microphysics HRT Data - [NetCDF]"
description="This data set includes airborne measurements obtained from the NCAR Research Aviation Facility (RAF) King Air aircraft (Tail
Number:
N312D) during the Second ISLSCP [International Satellite Land Surface Climatology Project] Field Experiment (FIFE-II). This dataset contains
high
rate navigation, state parameter, and microphysics flight-level data in NetCDF format."
platform_id=31
hide=1
The above example is the completed portion of the template which must be filled out. The rest of the template can usually be left alone but and
explanation of how it works and syntax is below.
- Set GENPROII dataset metadata The dataset_GP file contains the metdata data for the GENPROII dataset, it does not usually need to be edited as
it will inherit the metadata from the NetCDF dataset and replace "NetCDF" with "GENPROII" and reference the NetCDF dataset as a "superceded_by" dataset.
However, if the GENPROII dataset_id does not end in .002 or the NetCDF dataset does not end with .001 the dataset_id will need to be changes in dataset_GP.
- Insert: From the directory containing the metadata files run /net/work/Projects/g2n_conversion/scripts/ProjSetup.pl setup
Continue with step 2 of put the dataset into codiac here.
ProjSetup File syntax
There are three types of files, setup files, project data files, and dataset data files
- Setup Files:
A setup will contains a list of instructions and files to be executed by ProjSetup.pl
Currently there are only two inructions:
- add_project=proj
- add_dataset=dataset
Where add_project will add a project to CODIAC according to the metadata found in file "proj" and add_dataset will add a dataset according to
the metadata in file "dataset".
NOTE: The project must be added before you can add a dataset that belongs to that project. Also ProjSetup runs all or nothing, so if there is an error
in any of the datasets or projects you are adding all of the changes will be rolled back.
- Project Data Files:
These Files contain metadata for a project.
Synatx is: variable=value
Value Functions are also supported, See "Value Functions"
Currently the following variables are supported:
- (string) project_id
- (string) full_name
- (string) description
- (string: YYYY-MM-DD hh:mm:ss) begin_date
- (string: YYYY-MM-DD hh:mm:ss) end_date
- (int) minlat
- (int) maxlat
- (int) minlon
- (int) maxlon
- (int) internal_contact_id
- (string) parent_project_id
- (int) hide
- (string) dataset_id_prefix
add_xlink_where is a special variable, it will add all xlinks that match the supplied where clause
EX: add_xlink_where=href LIKE "%220%"
will add any xlinks where the URL contains "220" to the project
- Dataset Files:
These Files contain metadata for a dataset.
Synatx is: variable=value
Value Functions are also supported, See "Value Functions"
Currently the following variables are supported:
- (string) dataset_id
- (string) name
- (string) description

- (string) browse_param_prog
These are all just variables from tables in the CODIAC MySql Database tables related to datasets. Missing values would be simple to add if needed,
and I'm not sure exactly what all of these values control.
- Value Functions
I have created a small set of variable functions so that I do not have to put in the same information over and over. For example the GENPROII and
NetCDF datasets are almost identical except the work NetCDF is replaced by GENPROII.
Currectly Supported Variable Functions:
- Reference Function
- Syntax: variable=->FILENAME
ProjSetup will search the supplied file for variable and use the value found. (Supports Recusion)
- Syntax: variable=->FILENAME:variable2
ProjSetup will search the supplied file for variable2 and use the value found for variable (Supports Recusion)
- Replace Function
- Syntax: variable=VALUE;/.SRC->REPLACE
ProjSetup will replace all instances of SRC with REPLACE in VALUE
- Add Function
- Syntax: variable=VALUE;+NUM
numerically adds NUM to VALUE
- Append Function
- Syntax: variable=VALUE1;VALUE2
Appends VALUE2 to VALUE
Multiple Fuctions may be used, each function must be seperated by a semicolon (;), functions are evaluated from left to right.
Complex Example:
file1:
var1=100
file2:
var2=->file1:var1;+100;/.0->1;" values"
Result:
var2="211 values"
First 100 is retrieved from file1 (100), then 100 added to it (200), then all 0's are replaced with 1's (211), then " values" appended (211
values).

Jenna Bush Reacts To George W. Bush And Ellen DeGeneres: I ‘Personally Thought It Was Great’
by Shakiel MahjouriCount Jenna Bush Hager among those who were thrilled to see George W. Bush and Ellen DeGeneres sitting side-by-side.
Many, many people online were disappointed to see the “Ellen” host conversing with the former U.S. president at a Dallas Cowboys game in October. A number of celebrities and fans spoke out but Bush Hager will not be one of them.
“I personally thought it was great,” Hager Bush told People. “My dad likes people that think differently than him, that believe differently, and people are surprised by this… But my parents raised both [twin sister] Barbara and I had to have our own opinions.”
“Barbara and I were sitting around the kitchen table, and obviously we talked about a lot of mundane things, but if we had opinions we were allowed to share them,” the “Today” co-host continued.
Interacting with others who don’t share the same opinions is an important principle to Bush Hager: “I personally, and I think so many of us, miss a time where people who have different opinions get along.”
“I yearn for that. I want my kids to realize that we live in a world when people think tons of different things and we treat everybody with respect and kindness,” she added. “And so just like Ellen, my dad does that.”
“If you ask anybody that’s worked for him or knows him, plenty of the people that worked for him have different opinions or different lifestyles,” she concluded. “Thought different things and felt comfortable sharing that with him because he’s open.”

REST API Documentation
Building a back-end API layer introduces a whole new layer of coordination between server and client code. While there are many aspects to this delicate dance of communication, one key ingredient to minimizing back-and-forth-confusion-about what-call-does-what, is consistently communicating about your API endpoints.

This class handles our view details.
Located in /index.php (line 1103)
Displays our view. See render() for more information. All this class method does is echo the result of render().
Renders our view with variables intact, and then returns as a string. The view uses PHP Alternative Syntax.
Note all variables use underscores so as not to pass them to the view file. This is just a precautionary failsafe. We do an unset() on all variables we can before the require_once() call.
Note that the view path naturally mimics the controller path if you leave $_sFile empty.
Note the alternative syntax for the Action parameter of the path. For instance if you have /about for the URL, then this can map to either About/vDefault.php --OR-- About/vAbout.php. This helps in text editors by limiting the confusion with all the vDefault.php files.
Injects a variable into a view. What it does, in reality, is create a global constant which the view can read.
Note that View variables must be in UPPERCASE or an error is triggered.
Does the same thing as setCVar(), but does so with an array of vars at once.
Injects a variable into a view. The view can then access it via $this->VARIABLE.
Note that View variables must be in UPPERCASE or an error is triggered.
Injects a variable into a view. The view can then access it via $this->VARIABLE.
Note that View variables must be in UPPERCASE or an error is triggered. Note the difference with setVar() is that setVarH() assumes default ENCODE_HTML
Does the same thing as setVar(), but does so with an array of vars at once.
Is the inverse of setVar(). Is used to provide $this->VARIABLE functionality in the view for accessing variables that were previously assigned with setVar().
Note that View variables must be in UPPERCASE or an error is triggered.
Constant used by some of the class methods to indicate no desire to alter variable.
Constant used by some of the class methods to indicate we need to use htmlentities() on the variable.
Constant used by some of the class methods to indicate we need to use urlencode() on the variable.

Within this project, we are asked to use a software graphics program of our choice. I choose to try Adobe Photoshop CC 2017. We are also asked to select several images as backgrounds and thumbnails, in order to modify using gamma corrections. With this being my first time using Adobe Photoshop to modify images, I found getting used to image adjustment features within the software to be a bit of a challenge. Understanding the software just as much as creating within the software seems to be equally challenging. I would recommend Adobe Photoshop CC 2017 to any individual that would like to develop experience using image modifications and/or image illustration. I would also recommend trying other graphics software programs in order to obtain experiences that can assist with web site development.
Within this project, we are asked to find a large image to be used as what is referred to as an "image map" image. With this being my first time using image mapping, learning exactly how to image map an image in a new graphics software was definitely a challenge. I sought explanation from a link provided in order to fully understand all the details that put together an overall imap map. Initially, the different "shapes" requirement and "coords" drew a blank but I did my best to put together what I thought fufilled expectations. I also attempted to understand another links details, but resulted in an over complicated understanding letting me further realize my lack of experience with the new software graphics program I am using for trial. With the link provided, I learned how to use the graphics software features for image mapping as well as learning a cool way to put together my first image map image. This learning tool was one of the most educational for me. I look forward to gaining more experience with image mapping, especially with several different types of graphics softwares.
Within this project, we are asked to make image modifications to a couple of background images of our choice. The modifications to the background images are to be "Gamma Corrected". We are to choose a graphics software program to apply gamma corrections to our background images to give the images a "washed out" look. Applying the gamma corrections to my choice of background images was initially a bit confusing, but the end result broadened my understanding of the highlights brought about by gamma correcting. Within the requirements included image size adjustments as well, resizing several images into "thumbnail" image size adjustments. Several of my trials, adjusting the images size, resulted in a blurry appearance. After lots of trial and error, I decided on what appeared to be the most clear and fulfilled the required size adjustment.

NPM packages specify versions in the semver format: MAJOR.MINOR.PATCH
(e.g. 3.0.2
).
Increment MAJOR version when you have removed or changed a feature, and dependent modules will have to modified to be compatible with the new version.
Increment MINOR version when you have added a feature, but the module is backwards compatible.
Increment PATCH version when you have fixed a problem, but not broken or changed anything else.
Suppose a new module called pizza
gets published to NPM as version 0.0.1
.
When the author of the module decides to add some new functions
like .pepperoni()
it should get incremented to 0.1.0
.
When an issue on github is opened about a bug in .pepperoni()
and the bug gets fixed it should get pushed as 0.1.1
.
When the author goes vegetarian and eliminates the .pepperoni()
method it should be published as 1.0.0
.
there is some disagreement about the best use of 0.x.y
range semvers.
see this discussion
I suggest pubishing your module starting at 1.0.0
and after that,
incrementing the major version on each breaking change.
If you wish to indicate the stability of your module, do so in the README, in same way that node.js does. stability index
Module authors need to take care to correctly express the nature of changes with their version number, but it is the module user's responsibility to request sensible ranges.
Don't specify ranges that are too wide. The following may cause npm to install a version of a dependency that does not work with your module.
"dependencies" : {
"anything-goes":"*",
"greater-than": ">1",
}
It is best to specify modules that you know work.
"dependencies" : {
"patches" :"~1.3.7",
"major-minor":"1.4.x"
}
These ranges demand specific module major and minor versions, but allow patches. If the author of one of these modules publishes a patch, and it breaks your module (and you where using the module as documented) Then it was their fault, and you should post an issue.
This is also good.
"exact" : "3.5.2"
This should never break, however, you will have to update your module when a patch is released.


Although the term “Open Source Software” has only recently claimed widespread use, this phrasing originates in the American “hacker” culture of the 1960’s and 70’s.
More specifically, the practices behind the term are attributed to key individuals working in the computer science laboratories of Stanford, Berkeley, Carnegie Mellon and MIT.
a movement that supports the use of open-source licenses for some or all software.
Programmers who support the open-source-movement philosophy contribute to the open-source community by voluntarily writing and exchanging programming code for software development
There are many open source related websites that can be mined for rich data. Some of these websites include:
As members of OSS communities, OS participants share common interests and goals. One of the main emphases in OSS communities is the social interaction among participants through electronic communication.
Table below summarizes some of the more predominant cultural values seen in OSS communities:
Ideologies and values of open source software communities
Open source licensing encourages innovation through collaboration. Without it, many of the technologies we take for granted today would never have developed, or would be locked away behind patent law.
The open source movement is the reason that technology has developed at such a breakneck pace for the past few decades.

NWA 'Powerrr' Results (11/19): A New Phenom Rises, Former WWE Superstar Debuts, More
by Tom ClarkThe November 19 episode of NWA Powerrr came just seven days after the debut of a masked star who’s since taken over the program. The NWA World champion was also on hand this week and fans saw a very familiar face they knew from WWE.
The program began with a video rewind of last week’s episode and then kicked off with NWA World champion Nick Aldis. The National Treasure cut a promo and said that he would be facing Trevor Murdoch in an exhibition match. The crowd wanted Aldis to put the belt on the line but Nick said that Trevor was not in title contention.
Winner: Nick Aldis
A commercial for NWA’s pay-per-view was shown next. Into the Fire will take place on Saturday, December 14.
The Rock ‘N’ Roll Express came out and said they will defeat Wild Card to become the nine-time NWA World Tag Team champions. Wild Card came out afterward and said they don’t care how many times Ricky Morton and Robert Gibson have been champs, the veterans can kiss their a**.
A video rewind of The Question Mark’s debut was shown next, leading to the wildly popular newcomer’s match.
The Question Mark vs. Ricky Starks ended in a no contest
The match broke down Aron Stevens came in and attacked Starks. Stevens and The Question Mark double teamed Starks outside of the ring until guest commentator Colt Cabana came to the rescue. This leads to the announcement of the main event, pitting Stevens and Mark against Cabana and Starks
Eli Drake came out to cut a promo in which he talked about Ken Anderson. This brought Anderson out and the two men exchanged words. Anderson wanted to fight and Drake agreed, but Eli suckered Ken at the last moment. Drake ran Anderson into the ring post and then nailed him in the back with a turnbuckle hook.
A video rewind of Marti Belle and Thunder Rosa laying out Allysin Kay was shown next, leading to a women’s tag team match.
Marti Belle and Thunder Rosa defeated Allysin Kay and Ashley Vox.
During the match, former WWE Superstar Melina came out and distracted Kay long enough for Rosa to get the pin. After the bell rang, Melina stood tall with Belle and Rosa.
A commercial was shown next, featuring Austin Idol pushing what he called the “Kayfabe cocktail.”
The Question Mark and Aron Stevens defeated Colt Cabana and Ricky Starks
After the main event, Cowboy James Storm came out and cut a promo. Storm complained that Nick Aldis only wrestles exhibition matches and doesn’t defend the World title. Storm also said the same thing about NWA National champion Colt Cabana.
Suddenly, Kamille came out and whispered something into Storm’s ear. She left and Storm delivered his famous catchphrase, “sorry about your d**n luck!”

Ocellus is a work-in-progress decentralized image archiving network which strives to be resistant to censorship and targeted attacks. The stated goals of the project are:
The Ocellus network is made up of nodes. These can run the official Ocellus codebase, or any other codebase compliant with the Ocellus open protocol, which is likely to be based on WebTorrent and ActivityPub, open standards designed to enable easier communication between decentralized applications.
There will be two primary types of node: community nodes (also known as Booru nodes), and seed nodes (also known as Image nodes). Operators can choose to run one, the other, or both.
Community nodes will be federated together, and will be responsible for the community layer. Each community node will have the ability to determine its own rules as to what images can be uploaded, how those images should be tagged, and which other community nodes it wants to federate with. Operators will have full control over their own community nodes.
Most users will register on a single Ocellus community node and use that community node for all of their interactions with the network, including searching for, commenting on, and uploading images to other community nodes.
Image nodes will be fully decentralized, and will serve image files. When a user finds an image they want to view on a community node, that image will be downloaded transparently via webtorrent and presented on the user interface of the community node.
Image torrents will be de-duped via their hash. If a user uploads an image which does not already exist on the Ocellus network to a community node, that image will be transparently converted into a torrent file and the user will seed the image until it reaches saturation point. If a user uploads an image which already exists on the network, the community node will locate the existing torrent via its hash, and will immediately begin serving the image.
It is my belief that this coupling of federated community and peer-to-peer file sharing offers the most power to users, whilst also allowing for some moderation of community nodes (for example, a community node focused around pictures of trains will not have to show furry art in its search results). As running a node will not require the storage or traffic requirements to store the entire image library, this model is also incredibly friendly to Operators with less financial resources.
N/A. No functionality is implemented.


This is how we will unbutton: to cause an earthquake, which is to say
it was a disc, slipped, like a bone undone. What I look like from behind
walking away.
A transitive verb : is to open the folds of : to spread or straighten : expand,
as with an open map.
I like to stop
by continuing to move, like this, away from the first syllable of
I admit.
Twice, I brought the glass bottom down, hard
because of what you had said. I do believe
an omission is not a lie. It feels like the touch
of your shoulders is your attempt to embrace me.
In this effort I am only held when I reach back.
Do not confuse my dreams for centrifuge.
The brain hides fear so deep it cannot be released
except at night, asleep, small hands opening and closing,
opening and closing. A body is sometimes a door
slamming itself shut. A body is sometimes a pupil
getting smaller as one light gets brighter. I keep looking
at you like your face is a spread of tarot cards but I don't know
how to read tarot cards. What I do know is the stars inside of us
are not the same as the stars in the sky. I am a believer
in coincidence: the coin, flipping.

Bezier interpolation is always done in Lab space. Not needed for CartoColors. Max order: 5.
The lightness correction only works for sequential color scales, where the input colors are ordered by lightness. So this won’t work for diverging color scales, yet.
