This pages compares the width and heights for the same ul
element both using float (what would be its intrinsic preferred width) and templates. Some questions:
It seems that floats take all of this values into consideration, both for width and height. So I have changed the methods of the prototype that computes both values:
getComputedWidth
getComputedHeight
Both of them in domUtils.js
. Those methods are mainly called from other two methods of the same module: computeIntrinsicPreferredWidth
and computeIntrinsicMinimumWidth
.

Miley Cyrus Has Boyfriend Cody Simpson By Her Side on Her 27th Birthday!
Miley Cyrus is celebrating her birthday with boyfriend Cody Simpson!
The newly 27-year-old singer enjoyed a super low-key birthday on Saturday (November 23) with the 22-year-old Australian singer, family members, and close friends.
PHOTOS: Check out the latest pics of Miley Cyrus
Miley‘s older sister Brandi took to her Instagram Story to share a Boomerang of Miley wearing a crown on her head while blowing out the candles on her cake, as the 22-year-old Australian singer sits next to her.
Cody even took to Instagram to share a video of him and Miley along with the caption, “Happy birthday baby. Thanks for being you.”
Miley has been laying low out of the spotlight as she recovers from vocal cord surgery.


Installation¶
FIDL is just another Python package living within your local Python installation. There are two ways to install it:
Install from source¶
cd to the repository’s directory containing setup.py
Use your installation’s Pip:
pip install .
(for Release mode)pip install -e .[dev]
(for Development/Editable mode)
In development mode, Pip will install Pytest and some linters helpful while developing, and create symbolic links under Python’s packages directory instead of copying FIDL to it. This allows you to modify your .py
files and test on the fly, without need to reinstall every time you make a change.
Install from PyPi¶
FIDL is in PyPi. If you are able to reach PyPi, installing is as easy as:
pip install FIDL
Running tests¶
Load the test IDB putty.i64
(under tests/data) in IDA.
Now simply execute the pytest_fidl.py
script (under tests) from within IDA (Alt + F7
)
Warning
There is an issue related to testing with Pytest in Python3. Tests are not working for IDA with Python3 at the moment.

The GreenToThe10th website showcased content and design that was not reflective of their current services. GreenToThe10th was an outdated website and it needed a revamp, so I gave it a cosmetic facelift
The GreenToThe10th site hadn't been updated in a while, and there was a bunch of known customer pain points which needed to be addressed. My goal was to improve the user experience, modernise the aesthetic and increase sales.
My approach as a front-end developer for GreenToThe10th was to advocate for the user, and by putting the user first, we achieve business goals as a result. Having a wide range understanding of the following can assist in achieving strong user experience.
The client also wanted to have control over the website for future updates. Because of this, I decide to keep using WordPress.
The major problems I had to overcome in the design process were how to:
After a proper understanding of the issues, the main goals of the website redesign were established.
Some design challenges are harder than others, but when you have a great client to work with, it makes it that much easier to achieve your objective. I had a great time working with this client and I'm glad that I could help them create a brand and website that met their company needs.


Feature: Document
The `document` is exposed by default to cucumber steps. You can use it as a
more readable way to test if certain top level widgets exist on a page. For
example, using rspec you're able to write the following:
expect(document).to have_widget(<widget>)
Scenario: Check whether a widget exists in the document
Given the page /profile includes the following HTML:
"""

Guybrush Threepwood

"""
Given the following widget:
"""
class Name < Widget
root 'span'
end
"""
Then "document.has_widget?(:name)" should return "true"

Chapter 5 Revision: Sample Variance and Sample Standard Deviation; Hypothesis testing and Confidence Intervals
In this seminar, we revise the concepts of the standard deviation, the sampling variance, hypothesis testing and confidence intervals. We will also learn some more data manipulation and working with the random number generator.
5.1 Seminar
Let’s remove all objects from our workspace and set the working directory.
rm(list=ls())
setwd("~/statistics1")
5.1.1 Sample Variance and Sample Standard Deviation
The sample variance and sample standard deviation inform us about the degree of variability of our data. Suppose, we were to roll the dice 5 times. We could then compute the mean value that we roll. The sample standard deviation measures by how much an average roll of the dice will deviate from the mean value.
We start rolling the dice, using R’s random number generator and the runif()
function. The function randomly draws numbers from a uniform distribution. In a uniform distribution each value has the same probability of being drawn.  Hence, the uniform distribution.
runif()
takes three arguments. n
is the number of values to be drawn. min
is the minimum value and max
is the maximum value.
# random draw of 10 values from a uniform distribution
dice <- runif(n = 10, min = 1, max = 7)
dice
[1] 1.999577 1.230885 6.855672 3.836695 4.213343 1.285208 5.585894
[8] 5.195535 3.157857 5.577164
We have indeed drawn 10 numbers but they are not integers as we would like—we want to simulate a die, so the values should be 1, 2, 3, 4, 5 or 6. We will return to this in a moment but for now let’s return to the randomness. Let’s draw 10 numbers again:
# random draw of 10 values from a uniform distribution
dice2 <- runif(n = 10, min = 1, max = 7)
# first draw
dice
[1] 1.999577 1.230885 6.855672 3.836695 4.213343 1.285208 5.585894
[8] 5.195535 3.157857 5.577164
# second draw
dice2
[1] 2.746356 1.728629 5.308625 3.443253 6.641089 6.375807 2.991323
[8] 2.320698 4.432030 6.385851
The numbers of the first and second roll differ because we have drawn values at random. To make our results replicate and to ensure that everyone in the seminar works with the same numbers, we set R’s random number generator with the set.seed()
function. As argument we plug in some arbitrary value (it does not matter which but using a different one will lead to a different quasi-random draw).
# set random number generator
set.seed(123)
# random draw of 10 values from a uniform distribution
dice <- runif(n = 10, min = 1, max = 7)
dice
[1] 2.725465 5.729831 3.453862 6.298104 6.642804 1.273339 4.168633
[8] 6.354514 4.308610 3.739688
You should all have the same values. If not, run set.seed()
again and then do the random draw once. If you do it more than once, the numbers will change. Let’s see how this works:
# set random number generator
set.seed(123)
# 1st random draw of 10 values from a uniform distribution
dice <- runif(n = 10, min = 1, max = 7)
dice
[1] 2.725465 5.729831 3.453862 6.298104 6.642804 1.273339 4.168633
[8] 6.354514 4.308610 3.739688
# 2nd random draw of 10 values from a uniform distribution
dice2 <- runif(n = 10, min = 1, max = 7)
dice2
[1] 6.741000 3.720005 5.065424 4.435800 1.617548 6.398950 2.476526
[8] 1.252357 2.967524 6.727022
# reset random number generator
set.seed(123)
# 3rd random draw of 10 values from a uniform distribution
dice3 <- runif(n = 10, min = 1, max = 7)

As you can see, the the draws from dice and dice3 are the same and the draws from dice2 and dice4 are the same as well. Let’s make the values integers with the as.integer()
function which simply cuts off all decimal places.
# reset random number generator
set.seed(123)
# random draw of 10 numbers from a uniform distribution with minimum 1 and maximum 7
dice <- runif(10, 1, 7)
# cut off decimals places
dice <- as.integer(dice)

We have rolled a six relatively often. All sides should be equally likely but due to sampling variability, we have rolled the six most often. The expected value of a die is 3.5. That is: \[ 1 \times \frac{1}{6} + 2 \times \frac{1}{6} + 3 \times \frac{1}{6} + 4 \times \frac{1}{6} + 5 \times \frac{1}{6} + 6 \times \frac{1}{6} = 3.5\]
We compute the mean in our sample and the standard deviation. Let’s start with the mean. Do so yourself but do not use the in-built function.
dice.sum <- dice[1] + dice[2] + dice[3] + dice[4] + dice[5] + dice[6] + dice[7] + dice[8] + dice[9] + dice[10]
dice.mean <- dice.sum / 10
dice.mean
[1] 4
We would have gotten the same result from the mean()
function.
The sample standard deviation tells by how much an average roll of the dice differs from the estimated sample mean. Estimate the sample standard deviation on your own without using the sd()
function. Do not copy. Type everything yourself.
numerator <- ( (dice[1] - dice.mean)^2 + (dice[2] - dice.mean)^2 + (dice[3] - dice.mean)^2 +
(dice[4] - dice.mean)^2 + (dice[5] - dice.mean)^2 + (dice[6] - dice.mean)^2 +
(dice[7] - dice.mean)^2 + (dice[8] - dice.mean)^2 + (dice[9] - dice.mean)^2 +
(dice[10] - dice.mean)^2 )
std.dev <- sqrt( (numerator / 9) )
std.dev
[1] 1.763834
An average deviation from the sample mean is 1.76.
5.1.2 T test for the sample mean
Our estimate of the mean is 4. The expected value is 3.5. Is this evidence that the die is loaded? The null hypothesis is that the die is fair. The alternative hypothesis is that the die is loaded.
Answer this question on your own by computing and interpreting the t value.
# standard error of the sample mean
std.err <- std.dev / sqrt(10)
# t value
t.value <- (4 - 3.5) / std.err
t.value
[1] 0.8964215
Clearly, we cannot reject the null hypothesis. The estimated difference between our sample mean and the population mean is 0.5. This value is 0.9 standard errors away from the population mean under the null hypothesis (3.5). We do not know the critical value for the t distribution here because we are in a small sample. However, it must be bigger than 1.96. Our t value is clearly smaller, therefore, we cannot reject the null hypothesis. That is not surprising, given that we have drawn from a uniform distribution, i.e., our sampling process was fair by definition.
Let’s back up. The standard error quantifies the average difference between mean estimates that are due to sampling variability (chance). Put differently, the standard error approximates the average difference between the population mean and our sample estimate.
Now. Compute the variance of the mean on your own. Try yourself before you check the code.
# sample variance
variance <- numerator / 9
# variance of the mean
var.mean <- variance / 10
var.mean
[1] 0.3111111
The correct answer is 0.31. Now, compute the standard error of the mean from your variance of the mean. Try yourself.
\[ s^2_{\bar{X}} = \frac{s_{x}^2}{n} = (\sqrt{ \frac{s_{x}}{\sqrt{n}}})^2 \]
# variance of the mean
sqrt(var.mean)
[1] 0.5577734
Let’s estimate the p value from a t distribution with the correct amount of degrees of freedom.
p.value <- (1 - pt(t.value, df = 9))*2
p.value
[1] 0.3933733
The probability that we roll a fair die 10 times and get a sample mean of 4 is 39 percent. That is not unlikely at all. We are far from rejecting the null hypothesis.
We now construct the confidence interval around our mean estimate. To re-cap, we construct the confidence interval as:
\[ \bar{Y} \pm \mathrm{critical \: value} \times SE(\bar{Y}) \]
First, we need the critical value (for an alpha level of 0.05). We get the critical value from the quantile function of the t distribution with \(n-1\) degrees of freedom.
qt(p = 0.975, df = 9)
[1] 2.262157
where p
is the cumulative probability and df
is the degrees of freedom. The critical value in a t distribution with 9 degrees of freedom is 2.262157.
Construct the lower and upper bounds of the confidence interval yourself.
# lower bound
lb <- dice.mean - qt(p = 0.975, df = 9) * std.err
# upper bound
ub <- dice.mean + qt(p = 0.975, df = 9) * std.err
# confidence interval
lb
[1] 2.738229
ub
[1] 5.261771
With 95 percent probability (where the probability is the long-run relative frequency), the population mean is within the confidence interval.
Clearly, the population mean under the assumption that the null hypothesis is true (3.5), is within this interval.
Run a t test using the t.test()
function yourself.
t.test(dice,
mu = 3.5,
conf.level = .95)
One Sample t-test
data: dice
t = 0.89642, df = 9, p-value = 0.3934
alternative hypothesis: true mean is not equal to 3.5
95 percent confidence interval:
2.738229 5.261771
sample estimates:
mean of x
4
The t.test()
function is more convenient than estimating everything by hand. The results are the same.
5.1.3 T test for the difference in means
We will now test the difference between two dice. First, remove everything from the workspace on your own.
# remove everything from the workspace
rm(list = ls())
Set the random number generator to 1234.
set.seed(1234)
Generate a vector of 100 rolls of a fair dice on your own and show the results in a frequency table.
fair.die <- runif(n = 100, min = 1, max = 7)
fair.die <- as.integer(fair.die)
table(fair.die)
fair.die
1 2 3 4 5 6
21 28 6 20 13 12
The absolute number are not that great to see the distribution of values at a glance. Create a table that shows the proportions of each outcome.
table(fair.die) / sum(table(fair.die))
fair.die
1 2 3 4 5 6
0.21 0.28 0.06 0.20 0.13 0.12
Calculate the mean.
mean(fair.die)
[1] 3.12
Although, the proportions look like we rolled the lower numbers way too often, we are not too far away from the population mean (3.5).
 We draw randomly from a normal distribution with mean 4.5 and standard deviation 1.5.
loaded.die <- rnorm(n = 100, mean = 4.5, sd = 1.5)
loaded.die <- as.integer(loaded.die)
table(loaded.die)
loaded.die
1 2 3 4 5 6 7 8
2 13 19 28 23 8 6 1
Oops, we rolled 6 seven’s and 1 eight. Let’s change these to sixes. We use the square brackets to index the elements of the loaded.die vector. We use the which()
function to identify the elements that are greater than 6. Finally, we change these values to 6.
loaded.die[ which(loaded.die > 6) ] <- 6
table(loaded.die)
loaded.die
1 2 3 4 5 6
2 13 19 28 23 15
Now, estimate the 2 means (of the fair die and the loaded die) yourself. Next, estimate the difference in means. You may use the mean()
function.
# mean in the 2 groups
mean(fair.die)
[1] 3.12
mean(loaded.die)
[1] 4.02
# first difference (difference in means)
fd <- mean(fair.die) - mean(loaded.die)
fd
[1] -0.9
The difference suggests that we roll larger values with the loaded die. Is the difference statistically detectable? To find out, we carry out the t test for the difference in means. Our dependent interval scaled variable is the value of the roll of the dice. The our independent binary variable is whether the die is loaded or not.
Compute the standard error for the difference in means on your own.
\[ SE(Y_{X=0} - Y_{X=1}) = \sqrt{ \frac{s_{Y_{X=0}}^2}{n_{X=0}} + \frac{s_{Y_{X=1}}^2}{n_{X=1}}} \]
where \(s_{Y_{X=0}}^2\) is the variance in the first group and \(s_{Y_{X=1}}^2\) is the variance in the second group. The number of observations in the first group is \(n_{X=0}\) and the number of observations in the second group is \(n_{X=1}\).
The result is 0.2161462. Try until you get it. You may use the var()
function.
# standard error of the first difference
se.fd <- sqrt( ((var(fair.die) / 100) + (var(loaded.die) / 100)) )
se.fd
[1] 0.2161462
Now, that we have the standard error of the difference in means, compute the t statistic on your own (without using the t.test()
function).
# standard error of the first difference
t.value <- (mean(fair.die) - mean(loaded.die)) / se.fd
t.value
[1] -4.163848
The t value is large and our sample size is also large. We can take the critical from a normal distribution. For an alpha level of 0.05, the critical value is \(1.96\).
Construct the confidence interval for the difference in means yourself.
# lower bound
lb <- fd - 1.96 * se.fd
# upper bound
ub <- fd + 1.96 * se.fd
lb
[1] -1.323647
ub
[1] -0.4763534
The confidence interval for the difference in means ranges from -1.32 to -0.48. Clearly, the difference in means is smaller than 0. We can reject the null hypothesis that there is no difference between the loaded die and the fair die because 0 is not within the confidence interval.
Let’s estimate the p value: i.e., the probability that we estimate a difference in means of -0.9 given that there really is no difference between the fair die and the loaded die.
The result is 3.129287e-05. Try until you get it. You can use the pnrom()
function to get the cumulative probability from a standard normal distribution.
# 1st way
pnorm( t.value ) * 2
[1] 0.00003129287
# 2nd way
(1 - pnorm( abs(t.value) )) *2
[1] 0.00003129287
We can reject the null hypothesis.  Carry out the t-test.

AAX SDK
2.3.1
Avid Audio Extensions Development Kit
|
#include <AAX_IACFEffectGUI.h>
The interface for a AAX Plug-in's GUI (graphical user interface).
This is the interface for an instance of a plug-in's GUI that gets exposed to the host application. The AAX host interacts with your plug-in's GUI via this interface. See GUI interface.
The plug-in's implementation of this interface is responsible for managing the plug-in's window and graphics objects and for defining the interactions between GUI views and the plug-in's data model.
At initialization, the host provides this interface with a reference to AAX_IController. The GUI may use this controller to retrieve a pointer to the plug-in's AAX_IEffectParameters interface, allowing the GUI to request changes to the plug-in's data model in response to view events. In addition, the controller provides a means of querying information from the host such as stem format or sample rate
When managing a plug-in's GUI it is important to remember that this is just one of many possible sets of views for the plug-in's parameters. Other views and editors, such as automation lanes or control surfaces, also have the ability to synchronously interact with the plug-in's abstract data model interface. Therefore, the GUI should not take asymmetric control over the data model, act as a secondary data model, or otherwise assume exclusive ownership of the plug-in's state. In general, the data model's abstraction to a pure virtual interface will protect against such aberrations, but this remains an important consideration when managing sophisiticated GUI interactions.
You will most likely inherit your implementation of this interface from AAX_CEffectGUI, a default implementation that provides basic GUI functionality and which you can override and customize as needed.
The SDK includes several examples of how the GUI interface may be extended and implemented in order to provide support for third-party frameworks. These examples can be found in the /Extensions/GUI directory in the SDK.

Currently, I'm in my final year of college. I'm an intern at an Intellectual Property software firm and finally realized what I want to do next. My ultimate goal is to become a cyber-security analyst and thus, I'm working in the right path for it. I just had to talk to the right person in the company, and that was it; "This is how you CAN do it".
The biggest struggle I had, was trying to figure out how to get in the field in the first place. Back in freshman year, I was a slow learner when it came to coding. And now, I'm building mini projects left and right during my spare time. Whether it be working on my website, building web scrapers for both basic webpages and pages with that require login authentication, breaking into virtual systems with the Metasploit framework (or at least trying to), and struggling to cram for the Network+ and Security+ cert exams.
It's taken a while, but I love it. I was never a fan of deadlines. Instead, I always preferred doing things in my own time as well as creating stuff for myself. Just like music. I'll place it out on a public platform, but I won't market it towards everyone. It's just there so that it can be there. For me.
And now that my final year is closing in, I've been looking towards the next step on ways to keep moving up in the field. The plan is to look for work as a Network Engineer. It may not seem like much, but I can say with confidence that 70% of CyberSecurity relies on the foundations of networks. I've grabbed experience with Linux and currently learning UNIX from another employee in my current company. My supervisor has been instrumental with helping me with PowerShell and Python scripting for administration and networking. And then my managers and CIO have been supportive by allowing me into their meetings on new projects or SIEM incidents.
But the field of CyberSecurity wasn't just about being able to program. Some folks here work in the field in relation to Risk and Compliance. It may sound boring, having to deal with legal logistics, compliance with ISO standards and ensuring company standards meet the requirements of contract deals, but it's a huge part of it too.
And I'm having fun, weirdly enough.
And so as I look forth into moving further up into the field, I hope things start to get clearer. I'm hoping for challenges on the way to keep me motivated. I'm hoping I don't get too distracted by people's opinions. I'm hoping it works out.
Throughout college, I was not an "A" student. In fact, my first semester, I was a "D" student. And although on the verge of academic probation, I loved that I started that way. Because, that taught me, that I could make mistakes for 4 more years while at the same time improving and learning from those same mistakes.
I got the chance to grab my own time to think and figure out who I was, outside of a relationship. I got the chance to arrive 45 minutes late to a final exam (1-hour exam) and still get a 90% on it. I got the chance to switch my major 4 times. I got the chance to meet people I liked and people I disliked. I got the chance to try and create a start-up, which failed immediately. I got the chance, to meet CEO's from various companies. I got the chance to arrive on the first day of my internship all sweaty and gross. I got the chance to penny-board by the Charles river every morning to work. I got the chance to travel to New York and understand what all the hype was all about.
Most importantly, I got the chance to make mistakes.
And although it's been rough at times, where I had nights I just wanted to run away from everything, I got the chance to be fully vulnerable and value the support from my parents and sponsors back home. Because I got the chance to experience so much more than what I thought. In fact, I had certain expectations before I started, and HOLY CR** the reality was totally off at a different tangent.
So I guess Jupiter won't see me any time soon.
In fact, it'll take a while for me to get there.
I posted the "every day even now" video around the end of summer. Hoping it would grab at least some traction to the ambedo album.
Just enough to have a few critics hear my side of the story.
Because both sides can be very different.
For me, ambedo was about spontaneity in the moment. Being who you want to be during that one deep trance you have when you look at something beautiful or playing back one of those unforgettable memories. It was about being vulnerable with the music and venting out everything I felt during those multiple 3 a.m. sessions.
Because that's what they were.
But more so, ambedo is a story. My story. From my point of view. Each one of us carries an alter ego. Whether we believe in it or not. And at times, although contradictory and counter-intuitive, there are times where I feel that they are the same thing. Or at least everyone pretends they're to be separate entities. I've noticed times when I'm constantly chasing for something. Unsure as to where it would take me. Knowing that deep inside, it feels like the right path even though the fear of uncertainty revolves around it.
And the path forward never feels right when all we do is go up. And as we all struggle to climb the same ladder, for some, taking one step back is like crashing down into an abyss. When you're so used to that feeling, it's so easy to feel down.
And that's where ambedo truly comes in. In the moments of doubt. Struggle. And pure vulnerability.
And the deeper it sinks in, the easier it is to let gravity do the rest of the work for you.
---------------------------------------------------------------------------------------------------------------------------------------
"As if you could escape forever. You stop looking and learn how to be again. Like you've been remembering it. It's so easy to dream up for solutions and get dragged down into endless searching. But learning to stop living in the future will set you free." - srp
"Oh love, I don't mind. I'd never stop. You can't fall down." - vno
It's been 3 years.
And there's so much that has changed. No matter the variables present, I find myself bumping into a constant; the feeling I get when I look back. Even if it's just a glance.
And it's not to say that I haven't moved on. I have. It's just not the way I expected it would feel. I hoped the every time I'd peek into the past that it would be one of those rocking-on-a-chair-with-a-sunset-view vibes. Instead, I end up laying a tear. Unsure whether or not I truly miss it or not. Because I know that a part of me doesn't miss it. But I also know that it was the best a moment could be. So what's next? We're two different people now. If we met again, I'd probably not recognize her. You can't be in love with memories, can you?
Every day I make music, just to scratch it off my Pro Tools session over and over again, thinking that a supposed Eureka moment could happen. I thought that eventually I'd get to the point where I could express the feeling perfectly. That an emotion could give me a lyric or a ambient beat that would give me the perfect abstract sound. But touching on a past so sensitive means keeping it safe, deeply in the back of my mind.
And honestly, I think that's what it was. A sensitive memory. Bitter sweet to the point where it crushes you in the inside in such a beautiful way. Because it has no rhythm. It has no specific tone or word. It can't be heard. But it can be felt.
And that's the feeling I love the most. Playing it on repeat.

FROM DUSK TILL DAWN A film review by Mark R. Leeper Copyright 1996 Mark R. Leeper
Capsule: Robert Rodriguez and Quentin Tarantino team up to tell a crime and vampire story, an elaboration on a segment from 1973's VAULT OF HORROR. Then they turn up the violence and throw in a lot of visual effects. The result is fast but uneven, sometimes witty but sometimes strangely serious, occasionally entertaining but never worthy of the talents involved. Rating: 0 (-4 to +4). A very mild spoiler follows the review in which I discuss some sloppy aspects of the filming of scenes late in the film.
Let's say you are a video store clerk with some ideas of what you would like to see in films. So you make the crime film you have in mind, inspired by Hong Kong crime films, and it is a moderate success and popular with critics. You take most of your remaining plot ideas and combine them all in one script and surprise, the film is an international sensation. You bask in fame, but soon the question arises: just what do you do for an encore. The world is waiting for your next film expectantly. Can you imagine the pressure? What are you going to give us next, Mr. Tarantino? Well, there is an old Hitchcock plot you can turn into a short film for FOUR ROOMS. This time the critics are unimpressed. But your name is gold so you make another film. This time you dust off a horror script you wrote as a video clerk. So what happens? Well, in my opinion you have made a fairly standard video store sort of horror film, a hyper-version of a story that has been done before. FROM DUSK TO DAWN is somewhat dressed up with familiar actors and a big special effects budget, but these can not raise the film much above its modest origins. As director, Robert Rodriguez handles his characters and his first large budget well. Rodriguez is best known for his ultra-low-budget EL MARIACHI and still-low-budget DESPERADO. By his standards this is an epic spectacle film. But Tarantino, whose real forte is in creating the script, the writing is already a big step down. He needed to be associated with a strong film and this was not it.
The Gecko Brothers are loose and headed for the border. Richard Gecko (played by Quentin Tarantino) has helped Seth Gecko (George Clooney) escape from prison and the two are cutting a swath, killing and kidnapping their way to the Mexican border. Along the way they kidnap a family of three: widower and pastor Jacob Fuller (Harvey Keitel), his daughter Kate (Juliette Lewis) and son Scott (Ernest Liu). They sneak across the border and make for a rendezvous at a trucker and biker bar. The most sophisticated and stylish thing about this bar is its name, The Titty Twister. It is a place of drugs and sleazy strippers with wild bar fights during the day. Then after dark the folks really let their hair down and not, long after, their fangs. Yes, the whole bar is a front for a den of vampires. Our two killers and three hostages find themselves besieged by, if not an army, at least a platoon of vampires presented in the special effects tradition of FRIGHT NIGHT. If this plot seems new and creative you haven't seen the "Midnight Mess" chapter of 1973's VAULT OF HORROR.
FROM DUSK TO DAWN will be a real disappointment for most Tarantino fans. While his trademarked hyper-violence is present in all its gory glory, the dialog is not nearly so finely honed as it was in PULP FICTION. My guess is that Tarantino has not rewritten his script to give audiences the sort of writing characterizations--he has given to previous films. One place where this film does stand out is in one of Harvey Keitel's rare subdued performances.
FROM DUSK TO DAWN may well get the attention of the critics because of the names involved and the ad campaign, but more creative vampire films get made and go unnoticed to video stores and to cable. In specific, whatever creativity FROM DUSK TO DAWN has, it pales next to the latter two chapters of Ted Nicolaou's nearly unnoticed SUBSPECIES trilogy or Anthony Hickox's SUNDOWN: THE VAMPIRE IN RETREAT. You will find them on the same shelf of your video store where FROM DUSK TO DAWN will probably end up. I give the new film a 0 on the -4 to +4 scale. My suspicion is that Tarantino used up his creative plots on PULP FICTION and now his writing subsists of small borrowings from old Hitchcock plots and an Amicus anthology film, and a bit from NATURAL BORN KILLERS.
Spoiler..Spoiler..Spoiler..Spoiler..Spoiler..Spoiler..Spoiler..
While Rodriguez gives us some fast-paced action, much of it does not make a lot of sense. We once again have the BLOOD SIMPLE visual image of a dark and dusty room with bullets cutting holes in the walls so we see beams of light pierce the room. But Rodriguez does not do it right. Following a beam backwards should take you directly to a source the light. If the beams are from sunlight they should all be parallel. But Rodriguez has them pierce the room at all angles as if there are many suns in the sky. It is important to the plot of a vampire film that the beams of light be from sunlight as you can imagine. The same error was made in NEAR DARK.
A vampire must be staked through the heart to kill it. Technically the stake should pin the vampire's heart to the coffin, according to expert Montague Summers. But Rodriguez allows several scenes to pass where vampires are staked in the stomach.

Generates a word rank-based probabilistic sampling table.
make_sampling_table(size, sampling_factor = 1e-05)
| size | Int, number of possible words to sample. |
| sampling_factor | The sampling factor in the word2vec formula. |
An array of length size
where the ith entry is the
probability that a word of rank i should be sampled.
Used for generating the sampling_table
argument for skipgrams()
.
sampling_table[[i]]
is the probability of sampling the word i-th most common
word in a dataset (more common words should be sampled less frequently, for balance).
The sampling probabilities are generated according to the sampling distribution used in word2vec:
p(word) = min(1, sqrt(word_frequency / sampling_factor) / (word_frequency / sampling_factor))
We assume that the word frequencies follow Zipf's law (s=1) to derive a numerical approximation of frequency(rank):
frequency(rank) ~ 1/(rank * (log(rank) + gamma) + 1/2 - 1/(12*rank))
where gamma
is the Euler-Mascheroni constant.
The word2vec formula is: p(word) = min(1, sqrt(word.frequency/sampling_factor) / (word.frequency/sampling_factor))

Graham Norton begs Mel Giedroyc to 'let Bake Off go' on Children In Need
Mel Giedroyc was urged to let the Great British Bake Off ‘go’ during her presenting stint on Children In Need.
The 51-year-old presented the baking show for seven years alongside Sue Perkins, but they were replaced back in 2017 when the show moved from BBC One to Channel 4 – with Noel Fielding and Sandi Toksvig taking over.
But, despite no longer being on the show, she couldn’t resist dusting off a string of her best baking puns after praising staff and customers of Greggs for raising over £1million for charity.
‘Guys that is a lot of dough. See what I’ve done there? Dough? Because they make bread,’ she began.
‘I’m on a roll now, these puns aren’t half-baked. The best thing since sliced bread.
‘You won’t get batter than these, they’re a piece of cake to do.’
However, co-host Graham Norton was having absolutely none of it, telling her in no uncertain terms: ‘Mel, stop! Mel, you’ve got to let Bake Off go.’

A little harsh, hun.
Earlier in the evening, fellow presenter Ade Adepitan was forced to apologise to viewers watching on from home – as a young child was cut off live on air, just as he started playing the violin.
Viewers watching from the capital saw the live feed, direct from the Royal Mail sorting office, cut short as the show cut to an advert and then back to the studio.

‘We are experiencing technical problems in London,’ Ade confirmed. ‘So apologies for that.’
He then joked: ‘Probably some wet leaves in the wi-fi or something.’
The annual charity show is aiming to raise money tonight for disadvantaged children up and down the UK.
Last year, they managed to raise more than £50million.

During this uncertain time, I have nightmares, anxiety, and discontent. I dreamed about my family members, woke up felt like a crack in my chest. I don’t remember a thing in the dream; will I forget? Will I be forgotten? Like a bruise that I hadn’t have noticed before; when I do, it quite damages. The reoccurring feeling of the one’s far from home has swelled. The sense of missing pieces, the sore, and the pain lurking during the day caught me when I fall.
It’s been so long since I moved here. Where is it actually my home? I miss the time we sit together. How’s that sound like?
tracklists:
1 kitchen(here)-field recording in my aprtment in brooklyn, ny
2 garden(here)–field recording in my backyard in brooklyn, ny
3 calling–when the last time I call them
4 rubbing-irritation, uneasy
5 ringing-no one pick up
6 dinner table-recorded conversation with my brother at dinner table about uncertain future at home in bangkok(TH)
7 living room-recorded when my mom giving me hair cut, mom's childhood music in the background at home in bangkok(CHI)


A software built to deliver business value but coded ignoring business language will be unintuitive to change and will foster institutional knowledge that makes onboarding of new engineers a daunting experience.
One effective way to alleviate this is to encapsulate business rules in a specification object rather then leaving them as scattered relics that the next engineer will have to glue together and decrypt.
I will use Ruby examples throughout this article but the concepts are applicable to any programming language.
The example
Let’s say a company wants to automate its private driver booking business. Its clients are executives that don’t mind paying extra for a reliable service that can adapt based on unplanned events.
This is a simplified example adapted from a real application.
On Monday Alfred–Mr. David H.’s personal assistant–books him a limousine pickup for Wednesday at 11.20am from JFK International Airport with drop off in the Manhattan financial district.
The trip fits in a flat rate offered by a limousine service between two known locations so the system quotes the reservation 150$.
source = LocationRepository.find(name: 'JFK Airport')
destination = LocationRepository.find(name: '197 Broadway, New York, NY')
reservation_booking = ReservationBooking.new(source: source, destination: destination)
reservation_booking.create # => 12345
ReservationRepository.find(12345).quote # => $150
David flight land at JFK on time and the driver picks him up and start heading towards Manhattan.
source = LocationRepository.find(name: 'JFK Airport')
reservation = ReservationRepository.find(12345)
reservation.pickup(source)
During the trip David decides to make an unplanned stop in Brooklyn to have Ramen for lunch at Ganso.
location = LocationRepository.find(name: '25 Bond St, Brooklyn, NY 11201')
reservation.add_stop(location)
The driver parks at Central Parking a nearby garage–that charges 60$ per hours–and wait until David finishes his lunch.
location = LocationRepository.find(name: '276-300 Livingston Street')
reservation.add_stop(location)
reservation.add_incidental(kind: 'parking 1 hour', cost: 60)
When done David calls the driver to pick him up and shortly after that he’s dropped off at his penthouse in Manhattan.
location = LocationRepository.find(name: '195 Brodway, New York, NY 10007')
reservation.dropoff(location)
When David decided to made an unplanned stop his reservation changed from transfer to hourly rate and because of that the quote must be recalculated.
reservation = ReservationRepository.find(12345)
if reservation.quoted_type == :transfer && reservation.type == :hourly
quote = Booking::QuoteGenerator.new(reservation)
updated_quote = quote.recalculate
ReservationRepository.update(quote: updated_quote)
end
A more realistic challenge
Let’s add more requoting conditions to resemble the challenges you’d face in a real application. The quote has to be regenerated:
- before the trip starts and the client calls to change the vehicle type
- or after the trip starts and it was quoted for a number of hours and is now matching a more expensive point to point trip
- or after the trip starts and the driver had to reach an invalid area not usually served by the vendor requiring surcharges
We can create methods on the reservation entity like:
reservation = ReservationRepository.find(12345)
if ( reservation.quoted_type == :transfer && reservation.type == :hourly ) ||
( reservation.quoted_vehicle_type != reservation.vechicle_type ) ||
( reservation.quoted_type == :hourly && reservation.matching_more_expensive_point_to_point?) ||
( !reservation.driver.valid_zipcodes.include?(reservation.stops.zipcodes) )
quote = Booking::QuoteGenerator.new(reservation)
updated_quote = quote.recalculate
ReservationRepository.update(id: reservation.id, quote: updated_quote)
end
but if you didn’t know the code was evaluating the conditions I described above would you have been able to tell? Not very intention revealing.
The usual antipatterns
Plain Old God Object (POGO)
A step in the right direction would be to move those conditions on methods on the reservation entity: changed_from_transfer_to_hourly?
, changed_vehicle_type?
, travelled_to_invalid_area?
but that’s not its responsibility. Follow this approach and you will end up with a POGO a Plain Old God Object with hundreds of lines and too many responsibilities.
This is an antipattern I often find in Ruby on Rails and ActiveRecord objects but it affects every programming language.
Polluting other objects responsibilities
Moving these conditions within the Booking::QuoteGenerator
is a bad idea–it would be simpler to let that class just generate a new quote and delegate the evaluation of the trigger conditions elsewhere.
Perhaps the whole reservation update can be handled/hidden in a service object?
reservation = ReservationRepository.find(12345)
reservation_update_service = ReservationUpdateService.new(reservation)
reservation_update_service.execute
But we just moved the messy conditions inside ReservationUpdateService
a service class that now has too many concerns on when to trigger the update rather then just orchestrating it.
Refactor business logic with the specification pattern
I think our evaluation of an obsolete reservation quote should be delegated to another object. A Booking::ObsoleteQuoteSpecification
that can take care of these conditions and tell when to trigger the quote recalculation:
reservation = ReservationRepository.find(12345)
specification = Booking::ObsoleteQuoteSpecification.new
if specification.satified_by?(reservation)
quote = QuoteGenerator.new(reservation)
updated_quote = quote.recalculate
ReservationRepository.update(id: reservation.id, quote: updated_quote)
end
What is inside the specification class?
module Booking
class ObsoleteQuoteSpecification
def satisfied_by?(reservation)
@reservation = reservation
if changed_vehicle_type?
return true
else
return evaluate_quote_type_logic
end
end
private
def changed_vehicle_type?
# details omitted
end
def evaluate_quote_type_logic
if quoted_hourly?
return more_expensive_transfer_fare? || travelled_in_invalid_area?
elsif quoted_transfer?
return increased_stops?
end
end
def quoted_hourly?
@reservation.quote_type == :hourly
end
def more_expensive_transfer_fare?
# details omitted
end
def travelled_in_invalid_area?
# Evaluating if the reservation stopped in an invalid
# area for its vendor has significant business logic
# so I delegate it to a separate specification.
specification = InvalidAreaSpecification.new
specification.satisfied_by?(@reservation)
end
def quoted_transfer?
@reservation.quote_type == :transfer
end
def increased_stops?
# details omitted
end
end
end
The specification details on when to run a quote recalculation is now encapsulated leaving the wrapping code easier to test and without obscuring other object’s responsibilities.
This is separating how to match a candidate from the candidate object that it is matched against.
The candidate object is an entity in my example but the specification might also rely on a Repository to run dedicated queries. In some instance this could mean performance degradation that needs to be evaluated on a case by case. This is the workflow I follow for Ruby on Rails applications.
More comple specifications composed of multiple conditions can be treated as a composite.
Do not group all your specifications in a single directory! Their role is bound to a specific context–in my example booking–use it to locate the file and to namespace the class.
When not to use specification
Avoid specification for a single condition that applies to a single spot. Instead create an intention revealing method on the service or policy using it. If that condition starts to get used in multiple places reconsider the creation of a specification.
If the business owner talks repeatedly about a condition you should map it in code.
Conclusion
All but the simplest applications will have many conditions like the ones in my example–failing to surface them will do a disservice to your code longevity.
You can read more examples using the specification pattern on the paper written by Evans and Fowler. Lots of great examples in Domain Driven Design too.


public interface Serial
This interface provides a set of functions for 'Serial' communication.
Before using the Pi4J library, you need to ensure that the Java VM in configured with access to the following system libraries:
This library depends on the wiringPi native system library. (developed by Gordon Henderson @ https://projects.drogon.net/)

|---|---|
static String |
DEFAULT_COM_PORT
The default hardware COM port provided via the Raspberry Pi GPIO header.
|
| Modifier and Type | Method and Description |
|---|---|
void |
addListener(SerialDataListener... listener)
Java consumer code can call this method to register itself as a listener for serial data
events.
|
int |
availableBytes()
This method is called to determine if and how many bytes are available on the serial received
data buffer.
|
void |
close()
This method is called to close a currently open open serial port.
|
void |
flush()
This method is called to immediately flush the serial data transmit buffer and force any
pending data to be sent to the serial port immediately.
|
boolean |
isClosed()
This method is called to determine if the serial port is already closed.
|
boolean |
isOpen()
This method is called to determine if the serial port is already open.
|
boolean |
isShutdown()
This method returns TRUE if the serial interface has been shutdown.
|
void |
open(String device,
int baudRate)
This method is call to open a serial port for communication.
|
char |
read()
This method will read the next character available from the serial port receive buffer.
|
void |
removeListener(SerialDataListener... listener)
Java consumer code can call this method to unregister itself as a listener for serial data
events.
|
void |
shutdown()
This method can be called to forcefully shutdown all serial data monitoring threads.
|
void |
write(byte data)
This method is called to submit a single byte of data to the serial port transmit buffer.
|
void |
write(byte[] data)
This method is called to submit a byte array of data to the serial port transmit buffer.
|
void |
write(char data)
This method is called to submit a single character of data to the serial port transmit
buffer.
|
void |
write(char[] data)
This method is called to submit a character array of data to the serial port transmit buffer.
|
void |

write(String data,
String... args)
This method is called to submit a string of formatted data to the serial port transmit
buffer.
|
void |
writeln(String data)
This method is called to submit a string of data with trailing CR + LF characters to the
serial port transmit buffer.
|
