STAT 198- Blogging for Data Science
Students write 4 posts during the semester related to mathematics, statistics, computer science, and/or data science. Two blog posts can be about anything related to mathematics, statistics, computer science, or data science and are brainstormed using Andrew Gelman’s diary activity Two blog posts are more technical: a vignette style blog post and a data analysis focused blog post.
See the blogs here.

STAT 157- Communicating with Data: The art of writing for data science
The old adage, let the data speak for itself, is often poor advice. Without context it can be difficult (even impossible) to glean insights from statistical graphs and tables. In this seminar, students gain experience in how to write about their data insights in a way that is both compelling and faithful to the data. We explore a variety of genres from technical articles to news stories and blog posts.
In the seminar, students explore and analyse data and write about their findings. We also read and review both exemplary published analyses and students’ writing samples. We use modern statistical tools to work in a reproducible environment so that others may follow our decision-making process and recreate our analyses. By the end of the semester, students will have a portfolio of writing samples, including short pieces such as figure captions, Wikipedia entries, blog posts and news stories, and one technical paper.

“Mamma, did you hear what they were saying about Squinty?” asked Wuff-Wuff, as the boy and the two men walked away from the pig pen.
“Oh, yes, I heard,” said Mrs. Pig. “I shall be sorry to lose Squinty, but then we pigs have to go out and take our places in this world. We cannot always stay at home in the pen.”
“Yes, that is so,” spoke Mr. Pig. “But Squinty is rather young and small to start out. However, it may all be for the best.
“A journey is going away from home,” answered Mr. Pig.
“And does it mean having adventures?” asked Squinty, flopping his ears backward and forward.
“Yes, you may have some adventures,” replied his mother. “Oh dear, Squinty! I wish you didn’t have to go and leave us. But still, it may be all for your good.”
“We might hide him under the straw,” suggested Wuff-Wuff. “Then that boy could not find him when he comes to put him in a box, and take him away.”
“No, that would never do,” said Mr. Pig. “The farmer is stronger and smarter than we are. He would find Squinty, no matter where we hid him. It is better to let him do as he pleases, and take Squinty away, though we shall all miss him.”
“Oh dear!” cried Curly Tail, for she liked her little brother very much, and she loved to see him look at her with his funny, squinting eye. “Do you want to go, Squinty?”
“Well, I don’t want to leave you all,” answered the comical little pig, “but I shall be glad to go on a journey, and have adventures. I hope I don’t get lost again, though.”
“I guess the boy won’t let you get lost,” spoke Mr. Pig. “He looks as though he would be kind and good to you.”
The pig family did not know when Squinty would be taken away from them, and all they could do was to wait. While they were doing this they ate and slept as they always did. Squinty, several times, looked at the hole under the pen, by which he had once gotten out. He felt sure he could again push his way through, and run away. But he did not do it.
“No, I will wait and let the boy take me away,” thought Squinty.
Several times after this the boy and his sisters came to look down into the pig pen. The pigs could tell, by the talk of the children, that they were brother and sisters. And they had come to the farm to spend their summer vacation, when there was no school.
“That’s the pig I am going to take home with me,” the boy would say to his sisters, pointing to Squinty.
“How can you tell which one is yours?” asked one of the little girls.
“I can tell by his funny squint,” the boy would answer. “He always makes me want to laugh.”
“Well, I am glad I am of some use in this world,” thought Squinty, who could understand nearly all that the boy and his sisters said. “It is something just to be jolly.”
“I wouldn’t want a pig,” said the other girl. “They grunt and squeal and are not clean. I’d rather have a rabbit.”
“Pigs are so clean!” cried the boy. “Squinty is as clean as a rabbit!”
Only that day Squinty had rolled over and over in the mud, but he had had a bath from the hose, so he was clean now. And he made up his mind that if the boy took him he would never again get in the mud and become covered with dirt.
“I will keep myself clean and jolly,” thought Squinty.
A few days after this Squinty heard the noise of hammering and sawing wood outside the pig pen.
“The farmer must be building another barn,” said Mr. Pig, for he and his family could not see outside the pen. “Yes, he must be building another barn, for once before we heard the sounds of hammering and sawing, and then a new barn was built.”
But that was not what it was this time.
Soon the sounds stopped, and the farmer and the boy came and looked down into the pig pen.
“Now you are sure you want that squinty one?” the farmer asked the boy. “Some of the others are bigger and better.”
“No, I want the squinty one,” the boy said. “He is so comical, he makes me laugh.”
“All right,” answered the farmer. “I’ll get him for you, now that you have the crate all made to carry him home in on the cars.”
Over into the pig pen jumped the farmer. He made a grab for Squinty and caught him.
“Squee! Squee! Squee!” squealed Squinty, for he had never been squeezed so tightly before.
“Oh, I’m not going to hurt you,” said the farmer, kindly.
“Squinty, be quiet,” ordered his papa, in the pig language. “Behave yourself. You are going on a journey, and will be all right.”
Then Squinty stopped squealing, as the farmer climbed out of the pen with him.
 “Good-by!” he called to his papa and mamma and brothers and sisters, left behind in the pen. “Good-by!”
“Good-by!” they all grunted and squealed. “Be a good pig,” said his mamma.
“Be a brave pig,” said his papa.
“And—and come back and see us, sometime,” sniffled little Curly Tail, for she loved Squinty very much indeed.
 But he did not know how much was to happen before he saw his pen again.
“There you go—into the box with you!” cried the farmer, as he dropped Squinty into a wooden box the boy had made for his pet, with a hammer, saw and nails.
Squinty found himself dropped down on a bed of clean straw. In front of him, behind him, and on either side of him were wooden slats—the sides of the box. Squinty could look out, but the slats were as close together as those in a chicken coop, and the little pig could not get out.
He did not want to, however, for he had made up his mind that he was going to be a good pig, and go with the boy who had bought him for a pet from the farmer.
Over the top of the box was nailed a cover with a handle to it, and by this handle the pig in the little cage could be easily carried.
“There you are!” exclaimed the farmer. “Now he’ll be all right until you get him home.”
“And, when I do, I’ll put him in a nice big pen, and feed him well,” said the boy. Squinty smacked his lips at that, for he was hungry even now.
“Oh, have you caged him up? Isn’t he cute!” exclaimed one of the boy’s sisters. “I’ll give him the core of my apple,” and she thrust it in through the slats of the box. Squinty was very glad, indeed, to get the apple core, and he soon ate it up.
“Come on!” cried the boy’s father.  We must go for the train!”
“I wonder what the train is,” thought Squinty. He was soon to know. The boy lifted him up, cage and all, and put him into the wagon that was to go to the depot. Squinty knew what a wagon was and horses, for he had seen them many times.
Then away they started. Squinty gave a loud squeal, which was his last good-by to the other pigs in the pen, and then the wagon rattled away along the road.
Squinty had started on his journey.

OttWatch exposes several JSON/REST api pages to facilitate application development by third-parties, including other Apps4Ottawa contestants.
I'm comfortable handling the Mysql/GIS infrastructure if you're comfortable handling the fancy mobile apps and use cases I didn't bother with.
There is lots of room in the world for more than one solution. I only ask that you not abuse the API to the point that it brings down my server. Let me know if a particular dataset is missing, or a change in format would help you out.
I will do my best to not break existing features when updating the API - but no promises.
If you are using the API - please email me at<EMAIL_ADDRESS>so I can let you know if I'm about to break something.
Also: if usage gets crazy because just one person is being abusive to the API I may need to put it behind a username and password. So it's a good idea to email me when you start using it so I can give you a heads up if it ever comes to that.

Third-period rally propels Prince Albert Raiders past Regina Pats
Spencer Moe had two goals and an assist on Friday night, leading the Prince Albert Raiders to a 6-3 comeback win over the Regina Pats.
by Regina Leader-PostSpencer Moe had two goals and an assist on Friday night, leading the Prince Albert Raiders to a 6-3 comeback win over the visiting Regina Pats.
It was the third straight win for the defending WHL champions (10-2-3-0), who prevailed before 2,703 fans at the Art Hauser Centre.
Logan Nijhoff had two goals in a losing cause for the Pats (2-11-1-0), whose modest two-game points streak came to an end.
After a scoreless first period, Moe buried his first of the night 1:32 into the second. Drew Englot (first WHL goal) and Nijhoff responded to give Regina a 2-1 lead after 40 minutes, but the Raiders scored four straight in the third (Ozzy Wiesblatt, Reece Vitelli, Aliaksei Protas and Brayden Watts) to open up a 5-2 lead.
Nijhoff added his second of the night with 2:27 left in regulation before Moe rounded out the scoring 32 seconds later into an empty net.
Max Paddock made 35 saves for the Pats, who were outshot 16-7 in the third and 41-26 overall.
Raiders netminder Boston Bilous picked up the win.
EXTRAS: F Caiden Daley, acquired Tuesday from Brandon, notched one assist in his Pats debut … Protas had a goal and two assists while Ilya Usau added three helpers … Prince Albert went 2-for-4 on the power play. Regina was 0-for-3 … The Pats are back on home ice Sunday (4 p.m.) against the Red Deer Rebels.

Dogecoin, presented in 2013 has a fully copied the Litecoin algorithm with a couple of changes. Initially, there were generated 100 billion coins, and the number of coins in one block was set randomly. In March 2014, the currency behavior was changed. The reward has become fixed, and the issue is unlimited. The developer wanted to make new crypto and move away from the "black history" of bitcoins. In January 2014, Dogecoin community collected 50 thousand dollars for the Jamaica bobsled team, and on March 25 of the same year, users collected another 55 thousand dollars for NASCAR racer Josh Wise.
The work of DOGE crypto is based on the same principles as Bitcoin - the hash of public keys. The source code is also very similar - it was only slightly modernized. The main feature is the fast period of mining. A reward is given every 60 seconds. At the same time, there is no need to purchase expensive equipment - an ordinary personal computer will be enough to extract Dogecoin.
If at the beginning of the start of crypto there was no single value of one mined block, today the price is unified, which made DOGE even more similar to other cryptocurrencies.
An important feature of Dogecoin is the endless emission. This inhibits the growth of Doge price, but so far the developers do not plan to change this figure. Also, many users are attracted by a single commission for transfers. No matter what amount you will transfer, the cost of the service is always the same.
The main reason that so many users mine this particular cryptocurrency is that it does not need a powerful computer. Any personal computer easily turns into a getter of treasured coins. For most miners, calculating one block takes about three minutes. The process of mining itself is no different from the production of other cryptocurrencies. To get started, you need to have a Dogecoin wallet and install special software. It is recommended to download it from trusted sites - this way you will protect not only your computer but also your wallet itself.
There are two factors that can affect the rise of DOGEcoin price. The first one is the influx of new investors, who, when looking for promising coins, on anyone, stumbling upon articles about the DOGE price prediction. The second is the linear growth of the cryptocurrency market as a whole.
Dogecoin is built on a reward system and moving costs. The only possibility for coins occupying small niches to achieve some results, we mean to be able to do what Bitcoin can't and could never do. Dogecoin realized quickly that it was also easy to issue Bitcoin as cash bonuses. You can tell that this is quite problematic in view of the commissions for a transaction in Bitcoin and, perhaps, Doge has a chance to break through, but let's start with the fact that Dogecoin bonuses have never been issued "on-chain" (on the network), like Bitcoin bonuses (ChangeTip was a centralized service). If incentives come back into fashion, the Bitcoin ecosystem will easily cope with them.
Many other Altcoins are evolving to become something broader and more than just a crypto transaction platform, but Dogecoin follows its routes. It is currently widely used on platforms such as Reddit as a means of polling users for valuable content.
In June 2015, DOGE price reached a maximum level of 100 billion coins, although the price remains quite low compared to altcoins, which have a more limited amount. But the consistency demonstrated by Dogecoin and its constant presence among large online communities allowed him to gradually consolidate his place among the best altcoins.
According to strong fundamental features of DOGE, such as fast speed, low transaction costs, and security, it can become the crypto, that will revolutionize the transfer of values through the Internet and supplant most of the usual payment methods available today.
Dogecoin’s growing intrinsic value may attract more institutional interest in DOGE as an investment, as well as increase its speculative value. Smart money seeks value that goes deeper than just hype and speculation, and Dogecoin seems to have that value.
Many investors still cannot understand how Dogecoin gets on the new stock exchange or grows when the rest of the market falls down. Such an opinion is based on the fact that they still consider Dogecoin to be just a joke. However, in fact, Doge has long ceased to be a joke, it is more like something that could easily become the future of payments. And it will not be surprising if Dogecoin grows to $ 1 in the next decade.
#1 WalletInvestor Dogecoin Price Prediction
By the end of 2019, Dogecoin may certainly reach $0.00263
#2 CoinPredictor.io Dogecoin Price Prediction
In March Doge price will be around $0.00026.
#3 Theoofy.com Dogecoin Price Prediction
By the end of 2019 it's likely to see Doge price around the $0.0147 mark.

This is what I like to call a "missing feature" of Google
Calendar. I was inspiredby the fact that my coworkers could not see
my flights with the rest ofmy work calendar. Rather than sharing my
TripIt link with all my coworkers (eventhose who I didn't know needed
my travel plans), why not just import my TripIt intomy work calendar?
But by using the "Import Calendar" option in Google
Calendar, it is only a static upload and updates won't persist. Enter
persistant-cal!
The following tries to cover some possible questions.
- You may only request up to four calendar feeds.
-
Only calendar feeds from a predefined whitelist will be used. All
other feeds you supply will be ignored.
-
At this time, the whitelist is the following list of regular
expressions:
-
^((http|https|webcal)://|)www.tripit.com/feed/ical/private/[A-Za-z0-9-]+/tripit.ics$
-
Each event in your calendar(s) will be added to a private general
purpose Google Calendar.
-
You will be added as an attendee to the events specific to your feeds,
but will not have edit privileges over the Google Calendar events.
-
If another user has a feed with the exact same ID, they will also be
added to the Google Calendar event.

Circuit analysis in general is difficult, because not all components have exactly 2 leads, and not all components are static; rather, some behave dynamically. That is, in the general case, current and voltage measurements across the circuit can very over time. (Note that the term "circuit" is used loosely. Strictly speaking, a circuit is just one loop, but we use the term to mean a graph of electrical components.) Consequently, a circuit may have multiple steady-states, or no steady-state at all as things fluctuate over time, oscillate, or perhaps some combination of all such behavior.
Here, however, we're going to consider the case of circuits consisting of just resistors and batteries. In all such cases, there is just one steady state. This state can be described as the current and voltage levels measurable at every point in the circuit. Being steady, each such point measures a constant value for each of these two attributes. Our goal will be, given a circuit under the constraints thus named, what are the current and voltage levels at each principle point in the circuit?
Recall that voltage is a measure of difference in charge between two points in a circuit. So voltage at a point in a circuit refers to the difference in charge between that point and wherever ground can be found in the circuit.
What we find is that performing this analysis all just boils down to solving a linear system of equations after applying Ohm's Law and Kirkoff's votlage and current laws. And that's all there is to it.
Here are the steps that I believe are required.
Another thing to keep in mind when considering the direction of current flow is simply that of voltage level above ground. Current is trying to flow from high voltage to low voltage.
Remember that while the currents of two parallel paths (that split apart and join back together) may differ, their voltage drops are the same. Conversley, two paths in series share the same current reading, but their voltage drops may differ.
Only examples and practice will make this written description come into focus.
It's worth noting too that there is a recursive method for analyzing such circuits that is based on an understanding that networks of resistors act like a single resistor of a singular value. This understanding, along with a knowledge of how resistors combine in parallel and series, can sometimes be enough to fully analyze the kind of circutis we're talking about here, but not always.

We chose to create this website because Bryan and Sheldon have experience with Data Mining and Kyle had general web development experience. Lastly, Shane joined the group to help with debugging and e.
Currently the website is still in production. We have made a lot of progress on the website since Bryan had to parse the MovieLens dataset and Sheldon had to retrofit Python Code Users are able to register and log in to the website. Anyone is able to search our database for movies, but only registered users can rate and review movies. Registered users are also allowed to get a list of 15 movies to be recommended based off of their ratings of movies. The newest addition is a language filter. If a user tries to use profanity in a movie review then their review is not added and they are warned about their language usage.
We currently are in the process of adding additional admin privileges. Admins will be able to ban or delete users and add new movies.
We have error messages are already made on the backend, we just need to use Javascript to display the errors.
We are going to clean the site up a bit more to make it more mobile friendly
This information on the sidebar will probably be made into Modals to have cleaner code.

TATapestryRequest Class Reference
| Inherits from | NSObject |
| Declared in | TATapestryRequest.h TATapestryRequest.m |
Overview
A mutable class for building requests that are sent with @see TATapestryClient. Building a request adds parameters to the HTTP query string that will be sent to Tapestry Web API.
An example of building a request:
TATapestryRequest* request = [TATapestryRequest request];
[request addAudiences:@"aud1", @"aud2", @"aud3", nil];
[request addData:@"blue" forKey:@"color"];
[request addData:@"ford" forKey:@"make"];
[request listDevices];
[request depth:2];

XOR using MultiLayered Perceptron
28 Oct 2016Historically, almost every non-tree based ML algorithm created only linear separable spaces, and the XOR simply cannot be modeled with them. Enter the multilayerd perceptron (MLP) and everything changed. With an elegant chaining of linear combinations of inputs we can obtain almost any number of linear decision boundaries. So I thought I’d bulid a robust XOR gate using a simple MLP
| x1 | x2 | y |
|---|---|---|
| 0 | 0 | 0 |
| 1 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 1 | 0 |
The goal was to create a network which can learn these four points with as minimal setup as possible. And that would be one with one layer each for input, hidden and output nodes where the hidden layer has 2 neurons only.
To fit four points using a neural network is simple. Right?
It turns out, no. While it did classify correctly most of the times, there were instances when the network simply wouldn’t converge.
Why can’t it fit four points? Is Andrew Ng wrong when he claimed that a simple MLP can predict XOR? The answer: It depends on the way the weights are initialized. This will dictate, at which local minimum is the network going to converge.
To dig deeper into this I created a 3D graph of y vs (x1,x2) where z-axis is y, the output of our simple MLP. And depending on the weights the MLP will have a different linear separators and heights for each plateau.
The interesting observation is that a pair of plateaus on the opposite corners necessarily have highest and lowest z value. And this actually means a simple MLP can never fit an XOR gate since the ideal gate should have the opposite quadrants on same heights. This got me confused. Where does Andrew Ng’s claim fit into the picture? The answer is, the weights were built to fit the data. And this needn’t happen with random initializations.
This made me rethink my model. XOR is not about fitting four points, but working with the entire cartesian plane.
| x1 | x2 | y |
|---|---|---|
| negative | negative | 0 |
| positive | negative | 1 |
| negative | positive | 1 |
| positive | positive | 0 |
And this way, I generated thousands of pairs of real numbers (x1, x2) each between -10 and 10 and their corresponding y values. Almost every training instance gave only 85% accuracy.
This once again shows that a simple MLP cannot fit XOR data. The workaround is to increase the number of nodes in the hidden layer, and this in turn creates multiple plateaus which will only fit the data and not generalize

Initializes the Gaussian process (GP) object with the observations and a kernel type.
Parameters: - x – The locations of the observations to condition the GP on; should have shape [nSamples x nDimensions].
- y – The values of the input at the locations given by x. Should have shape [nSamples].
- kernel – The name of the kernel to use. Must be one of:
Exponential
,Squared Exponential
,Matern(3/2)
, orMatern(5/2)
Returns: The Gaussian processes object for further use.
-
draw
(self, xTest, Size nDraws=1)¶ Draws a random vector from the Gaussian process at the specified test points.
Parameters: - xTest – the points to make predictions at. Should be [nPoints x nDimensions].
- nDraws – the number of draws to produce. The first draw is much more computationally than subsequent draws.
Returns: A matrix of values sampled from the Gaussian process. [nDraws x nPoints]
-
gradient
(self, xTest)¶ - Computes the expected gradient of the Gaussian process at a given point.
- Each component i is dy/dx_i.
Parameters: xTest – the point to measure the gradient at. Should be [nDimensions]. - Returns
- The components of the gradient as a vector of length [nDimensions].
-
logLikelihood
(self, __Pyx_memviewslice params=None) → double¶ Computes the log-likelihood of the Gaussian process for the given parameters, x, and y.
Parameters: - params (optional) – the parameters of the kernel to use. Otherwise use whatever is
- in self.params. (currently) –
Returns: The log-likelihood as a double.
-
optimizeParams
(self, paramsGuess=None, tol=1e-3, logBounds=[(-10, 10), (-5, 5), (-10, 10)], fixWhiteNoise=None)¶ Attempts to locate the maximum likelihood parameters for the given x and y.
Parameters: - params (optional) – the kernel parameters to start from. Otherwise use whatever is currently in self.params.
- tol (optional) – the error allowed by the optimizer before it is considered to be converged.
- logBounds (optional) – the bounds on the log of the parameters to be optimized. This is important for avoiding implausible parts of parameter space which would cause positive-definite errors in the Cholesky computation.
- whiteNoise (optional) – a value to fix the white noise at. If none, fits the white noise along with the other parameters.
Returns: The optimized parameters (which are also written to self.params).
-
precompute
(self, __Pyx_memviewslice params=None, bool force=False) → int¶ - Conducts essential precomputation for the Gaussian Process.
- Specifically, this constructs the covariance matrix, the Cholesky thereof (L), and alpha = L.T * L * y. For certain inputs, the numerics are not very stable, and so the Cholesky operation may incorrectly determine that the covariance matrix is not positive definite. This is best resolved by using a small amount of white noise (a diagonal addition to the covariance matrix); see parameter information.
Parameters: - params (optional) – the parameters of the kernel to use. Otherwise use whatever is currently in self.params.
- force (default False) – Recompute even if cholesky and alpha are flagged as fresh. This shouldn’t be necessary under normal conditions, since it is automatically set to True if params is not None.
Returns: 0 if successful, otherwise -1.
-
predict
(self, xTest, bool getCovariance=True)¶ Compute the Gaussian process’ prediction for a given set of points.
Parameters: - xTest – the points to make predictions at. Should be [nPoints x nDimensions].
- getCovariance – Whether to get the predictive covariance as well as the mean.
Returns: A vector of predicted means and (if getCovariance==True), the covariance matrix of the predictions. For reference, the marginal uncertainties are np.sqrt(np.diag(var)).
-
setY
(self, newY)¶ - Changes the measured y values in a way that minimizes the required recomputation.
- Specifically, this will need to recompute alpha O(n^2) but not the Cholesky O(n^3)
Parameters: newY – the new values of y to use. Should be [nPoints]. Returns: None
Example Use¶
import numpy as np
from matplotlib import pyplot as plt
from sam import GaussianProcess
x = np.linspace(0,10,10)
y = np.sin(x)
f = GaussianProcess(x,y)
f.optimizeParams(5*ones(3))
xTest = np.linspace(0,10,100)
yTest, yErr = f.predict(xTest)
yErr = np.sqrt(np.diag(yErr))
plt.plot(xTest,yTest)
plt.fill_between(xTest,yTest-yErr,yTest+yErr,alpha=.5)
plt.plot(x,y,'.')


Russia’s deputy foreign minister Sergei Ryabkov told Interfax news agency that the Russian government maintained "contacts" with Trump's “immediate entourage.” He also said, “We continue to do this and have been doing this work during the election campaign,” he said. The Russian foreign ministry later said there were no contacts with Trump's campaign staff, but rather with American politicians and supporters, and Trump spokesperson. Hope Hicks denied the campaign was aware of any contacts between campaign representatives and Russian officials prior to the election.

Review of Star Wars: Episode I - The Phantom Menace (1999) Written and Directed by: George Lucas Rating: **1/2 out of ****
Perhaps the only thing I find more disturbing about the fact that I had to give such a disappointing rating to the first episode of Star Wars, is the fact that part of me feels overly generous about it. I mean, I'm talking about Star Wars, the film series that has transcended the boundaries of the silver screen and infused itself as part of our social consciousness. Everyone who is alive and actually interacts with the rest of society knows the story of Star Wars; and they know who all the characters are; and they know at least a handful of quotes from the film. Even if they've never seen the movie.
So I find myself in a rather frustrated position when I have to sit down and announce that this film simply isn't as great as it's predecessors, because the reality is: it isn't.
The story opens as two Jedi knights: Qui-Gon Jinn (Liam Neeson) and Obi-Wan Kenobi (Ewan McGregor) set out to diffuse a potentially hostile situation dealing with unfair taxation levied against the small planet of Naboo by the Federation. Unfortunately, for all those involved, the hostile situation changes from potentially to authentically, and the Jedis have to rescue the Queen of Naboo (Natalie Portman) before she is taken prisoner. Eventually they all leave Naboo to find Anakin Skywalker (Jake Lloyd).
 Now if I were forced to point out one reason why I had such distaste for this film, well it's Jar Jar Binks. In all honesty, this character should have been completely written out of the picture. His brand of intellectually deprived humour is so unbearably annoying, that I'm still in shock that Lucas thought it was a good idea to include him in the cast. The pain of having to watch this character is roughly equivalent to someone screeching their fingernails endlessly on a chalkboard hooked up to a guitar amplifier turned up to 10. If the mindless banter provided by C3P0 even slightly annoyed you in the previous films, prepare to be squirming in your seat and squinting in pain as you endure the cinematic catastrophe that is Jar Jar Binks. After enough exposure to this character, I was lamenting the fact that the concession stand didn't sell painkillers to help ease my Jar Jar viewing experience.
This illustrates another fundamental problem of Episode One: the tone of the picture is far too light-hearted. Not for one minute did I feel that any of these characters were in any real danger (with the exception of the Jedi duel towards the end of the picture, but I'll discuss that later). There are also no characters which challenge what's being presented to them, they just sort of go from point A to point B as if their lives are a scripted movie (and although there's a pretty cool sense of irony about that, it's not a good thing). In the previous three films, Han Solo was the character whose motivations were, to a certain extent, guided by personal interest. He also perfectly counterbalanced the juvenile antics of C3PO. None of that is present in this picture.
However, it would also be a mistake to argue that there is nothing in Episode One which deserves commendation. Of course, the special effects are breathtaking, and the scenes which focus on the Jedis are especially interesting. If the film had only decided to examine more of the lives of the Jedis and brought more screen time to the antagonist Darth Maul (Ray Park); Episode One could have easily been the greatest entry into the series. The lightsaber fight between Obi-Wan Kenobi, Qui-Gon Jinn and Darth Maul is absolutely incredible and managed to alleviate a lot of the boredom I felt from earlier parts in the film.
I really wanted to love this picture. Personally speaking, I love the Star Wars trilogy - not in the quasi-insane "I'll camp out for eight weeks to get tickets for a movie that will be in theatres for eight months" way, but I do think they're really great movies. What Lucas has produced with The Phantom Menace unfortunately resembles a two-hour cartoon rather than an epic tale of good and evil. I hope that future Star Wars films will be an improvement over this one.

In maintenance mode Acquire contains all measurement data acquisition methods. In Inspection mode only rates only, background, normalization, verification and holdup are available.
The data acquisition methods are rates only, background, initial source, normalization, precision, verification, calibration and holdup. Each of these data acquisition methods has at least one setup dialog box that you must fill in to acquire data. The following data entry elements are common to all data acquisition methods:
Comment
Count time
Option to acquire using number of cycles or measurement precision
Number of cycles
Precision, minimum and maximum number of cycles for measurement precision acquisition
Data source
QC tests
Print results
Display results options
Ending comment option
Comments are optional.
A measurement consists of the number of good cycles requested, for example, 10 cycles of 100 seconds each or the number of cycles needed to achieve the requested precision.
The data source can be shift register, database, disk file or manual entry. For background, normalization and verification measurements only, the data source can be ‘review disk file’, indicating that the data came from either the Shift Register Review or Radiation Review program:
"Shift register" is the normal data acquisition mode from shift register electronics.
"Database" refers to the database of previously acquired measurement data.
"Disk file" refers to specially formatted disk files that allow arbitrary measurement data sets to be analyzed.
“Manual entry” allows the user to type in a count time, measurement date and up to 200 sets of totals (singles), reals plus accidentals and accidentals.
"Review disk file" refers to measurement data files that have been exported from the Shift Register Review or Radiation Review program in NCC format.
If you select "Database" as the data source, you will get an inverse chronological list (most recent first) of previous measurements of the same data acquisition method. When you select one of the previous measurements, the raw measurement data for that measurement are read from the database and are processed as though they came from the shift register. All of the parameters that are used to process the data are the current parameters in the database. This allows you, for example, to reanalyze old measurement data with different background, deadtime, calibration coefficients, etc. Measurements can only be reanalyzed one at a time.
Disk files are primarily intended for software diagnostics, but can also be used to import measurement data that were acquired without the use of this program. You can find the required format for these disk files in “Test data file format”. If you select "Disk file" as the data source, you will be asked to enter or select the filename for the file that contains your data. Each measurement must be in a separate file.
Manual entry is primarily intended for software diagnostics, but can also be used to import measurement data that were acquired without the use of this program.
You can acquire data with or without the quality control tests on. You should have the quality control tests on unless there is a special need to turn them off. The quality control tests that you can turn off are the accidentals/singles test and the outlier test. These are explained in “QC and Test parameters”. If the box labeled "QC tests" is checked, the quality control tests are turned on.
If the box labeled "Print results" is checked, the results will be printed at the end of each measurement. While a results text window is displayed, you can print it by clicking in the upper left corner of the window and then selecting “Print” from the drop down menu. If you do not print the results at the end of each measurement, you can print them later by selecting Report.
Check the ending comment box if you want to be able to add a description of the measurement when it has completed.
You can select the detail to display and print by checking boxes for the desired options under Setup | Facility/Inspection.
When the doubles rate is obtained from the calculated accidentals coincidence rate, the doubles rate for a complete measurement is calculated as the average of the doubles rates for the individual cycles and differs slightly from the doubles rate calculated from the summed raw data; this method was chosen because the calculation assumes that the singles rate is constant during the data collection, and this is more likely to be true for each cycle than for the entire measurement.


Founders Memorial: Reminder of the huge vacuum left behind by 1G leaders
- Advertisement -
As the speech-impaired 4G leaders continue to get themselves exposed as less than worthy successors to the giants of yesteryear, the Founders Memorial, which will remind us of the huge vacuum left behind, is taking shape. It’s down to a shortlist of five designs, with the winning design to be announced next year. I just want to offer my humble thoughts on the whole exercise.
The five designs are outstanding and world-class. The competing teams – 8DGE + RSP Architects, Cox Architecture + architects61, DP Architects, Johnson Pilton Walker + RDC Architects and Kengo Kuma & Associates + K2LD Architects – have done themselves proud. Every one of the designs would capture well the concept of commemorating the founding fathers’ contributions and the values that shaped the country. My personal choice is the Cox Architecture + architects61 design. It is bold and striking – encapsulating the spirit of the 1G pioneers.
Even at this stage, however, it should not be too late to tell the people in charge of the project that there are certain things they should consider when executing Exercise Founders Memorial.
The memorial should:
- Advertisement -
Celebrate and educate
Please do not let it be yet another ugly effort to push through a particular narrative and ignore the part played by others along the road to Merdeka. The People’s Action Party 1G leaders were not the only ones involved in the fight for independence. Even the last British governors helped usher the island into self-government. Robert Black and William Goode (who in fact was the first Yang di-Pertuan Negara before Yusof Ishak who later became Singapore’s first President) did not leave the state in chaos during the transition. Thankfully.
All the highly motivated and capable adversaries of Lee Kuan Yew were fighting for a common cause – the end of colonial rule. They should not be ignored or forgotten. They were anti-colonial compatriots within the PAP before they exiled themselves, got detained or split up to form the Barisan Sosialis. Ong Lian Teng, father of Education Minister Ong Ye Kung and Barisan MP for Bukit Panjang, was one of them, together with Lim Chin Siong and Lee Siew Choh. Dominic Puthucheary, father of Senior Minister of State (Communications and Information) Janil Puthucheary, was another.
And whatever is planned for the story projection within the memorial should include the part played by David Marshall and Lim Yew Hock (the first two Chief Ministers when Singapore attained self-government) and Ong Eng Guan, the first Mayor, who was effectively the most senior PAP government leader until LKY came into the picture.
The FM planners should not be arbitrary and one-sided in their interpretation of Singapore’s history. If they are, they will be performing a great disservice to history and the country.
Have emotional impact
The memorial must connect strongly with whoever visits it. The visitor must be able to feel and share the spirit and motivation of the leaders in their moments of uncertainty and decision. And it must go beyond being just a paean. It has to be a sharing experience. And this sharing is simply not possible with rah-rah cardboard and Disneyland-like narratives. Dig deep for the right approach.
Be an oasis for reflection
The memorial is not a shrine where people have to genuflect and do their rituals. It is more a triumph but it should also be a place to reflect. So the final plans should bear in mind not to allow visitors (or operators) to turn the memorial into a noisy pasar malam.
Allow a rejection vote
It would be useful to gauge to what extent ordinary Singaporeans identify with or even support the memorial. In the online feedback on the designs, give Singaporeans an option 6 – to say NO to the shortlisted designs – and/or option 7 – to totally reject the idea of a founders memorial.
Get their feedback as part of the process of embedding the Founders Memorial in the psyche of a still new and evolving nation. Putting up a physical structure is only the beginning and not an end in itself.
Fifty years from now, it should be an organic part of the Singapore identity, that they can be intimately familiar with these pioneers as, for example, Americans are with theirs. If not, the memorial would have been an expensive failure and nothing more than a piece of vanity.

🤖 Analyze and Test robots.txt Files on a Large Scale
Even though they are tiny in size, robots.txt files contain potent instructions that can block major sections of your site, which is what they are supposed to do. Only sometimes you might make the mistake of blocking the wrong section.
So it is very important to check if certain pages (or groups of pages) are blocked for a certain user-agent by a certain robots.txt file. Ideally, you would want to run the same check for all possible user-agents. Even more ideally, you want to be able to run the check for a large number of pages with every possible combination with user-agents.
To get the robots.txt file into an easily readable format, you can use the
robotstxt_to_df()
function to get it in a DataFrame.

Bulk robots.txt
Tester
This tester is designed to work on a large scale. The robotstxt_test()
function runs a test for a given robots.txt file, checking which of the
provided user-agents can fetch which of the provided URLs, paths, or patterns.
import advertools as adv
adv.robotstxt_test(
robotstxt_url='https://www.amazon.com/robots.txt',
user_agents=['Googlebot', 'baiduspider', 'Bingbot'],
urls=['/', '/hello', '/some-page.html'])
As a result, you get a DataFrame with a row for each combination of (user-agent, URL) indicating whether or not that particular user-agent can fetch the given URL.
Some reasons why you might want to do that:
SEO Audits: Especially for large websites with many URL patterns, and many rules for different user-agents.
Developer or site owner about to make large changes
Interest in strategies of certain companies
User-agents
In reality there are only two groups of user-agents that you need to worry about:
User-agents listed in the robots.txt file: For each one of those you need to check whether or not they are blocked from fetching a certain URL (or pattern).
*
all other user-agents: The*
includes all other user-agents, so checking the rules that apply to it should take care of the rest.
robots.txt Testing Approach
Get the robots.txt file that you are interested in
Extract the user-agents from it
Specify the URLs you are interested in testing
Run the
robotstxt_test()
function
fb_robots = adv.robotstxt_to_df('https://www.facebook.com/robots.txt')

Now that we have downloaded the file, we can easily extract the list of user-agents that it contains.
fb_useragents = (fb_robots
[fb_robots['directive']=='User-agent']
['content'].drop_duplicates()
.tolist())
fb_useragents
['Applebot',
'baiduspider',
'Bingbot',
'Discordbot',
'facebookexternalhit',
'Googlebot',
'Googlebot-Image',
'ia_archiver',
'LinkedInBot',
'msnbot',
'Naverbot',
'Pinterestbot',
'seznambot',
'Slurp',
'teoma',
'TelegramBot',
'Twitterbot',
'Yandex',
'Yeti',
'*']
Quite a long list!
As a small and quick test, I'm interested in checking the home page, a random profile page (/bbc), groups and hashtags pages.
urls_to_test = ['/', '/bbc', '/groups', '/hashtag/']

For twenty user-agents and four URLs each, we received a total of eighty test results. You can immediately see that all user-agents not listed (denoted by * are not allowed to fetch any of the provided URLs).
Let's see who is and who is not allowed to fetch the home page.

I'll leave it to you to figure out why LinkedIn and Pinterest are not allowed to crawl the home page but Google and Apple are, because I have no clue!

For research purposes and if you want to download more than ~500 files, you might want to use
output_file
to save results as they are downloaded. The file extension should be ".jl", and robots files are appended to that file as soon as they are downloaded, in case you lose your connection, or maybe your patience!>>> robotstxt_to_df(['https://example.com/robots.txt', ... 'https://example.com/robots.txt', ... 'https://example.com/robots.txt'], ... output_file='robots_output_file.jl')
To open the file as a DataFrame:
>>> import pandas as pd >>> robotsfiles_df = pd.read_json('robots_output_file.jl', lines=True)
- Parameters
robotstxt_url (url) -- One or more URLs of the robots.txt file(s)
output_file (str) -- Optional file path to save the robots.txt files, mainly useful for downloading > 500 files. The files are appended as soon as they are downloaded. Only ".jl" extensions are supported.
- Returns DataFrame robotstxt_df
A DataFrame containing directives, their content, the URL and time of download
