My name is Drew Baker and I am a creative, solution-oriented software developer.
I'm originally from Oxford, MS, and have a Bachelor's in Computer Science from Mississippi State University.
Currently, I'm working remotely for Capital One, and once/if we go back to the office, out of their North Texas people center.
While I thoroughly enjoy a good problem to solve or feature to implement, my true passions are visual and experience design. For me,
there's no greater feeling than taking an idea, building on it from the ground up, and refining it into a useful, usable system that users
enjoy. Even though my heart lies in the user experience, I've got plenty of experience working in a full-stack capacity as well. Outside of work,
you'll probably find me behind a video camera, outdoors with my dog, or watching Mississippi State baseball.
Hail State!

AC/DC is not only an iconic band, but a legendary band as well. They are an Australian rock band formed in Sydney in 1973 by Scottish-born brothers Malcolm and Angus Young. Although their music has been variously described as hard rock, blues rock, and heavy metal. It is true what they say, good music grows with age like a fine wine gets better over time
This song was released in the year 1980. Here is a link to the original song. It is well known that it has been used in quite a number of movies, let's not forget Iron Man.
The band gitarist Angus Young said to have come up with the idea of the song while sitting on a toilet. The song was released in the year 1979. Click Here to watch the original song. It is well known that it has been used in quite a number of movies, let's not forget the movie Mega Mind
Guitarists Angus and Malcolm - wrote this song. They would often tell a story about how the song came about when Angus was flying in a plane that was struck by
lightning and nearly crashed. This is one of the best song ever for physical motivation

Amateurism is an excuse to subjugate young, talented athletes.
Classify them as employees. Pay them a fair wage. Let them unionize.
The NCAA caps sport participation at 20 hours a week in season, and 8 hours out of season. That's a joke.
Many athletes struggle to pay rent and groceries.
Student Athletes deserve a trade union. It's time for colleges and athletic departments to recognize them as the collective bloc they are.

Twinkies being turned into breakfast cereal
Post said it will taste just like the treat
by Jordan Valinsky, CNN Business(CNN) - More than six years after a Twinkies shortage gripped the United States, the sweet snack is stronger than ever and taking on new forms.
Post is partnering with Hostess to turn the 90-year-old treat into a cereal that will be available nationwide in late December. The taste of Twinkies Cereal "replicates the distinctive taste and familiar oblong shape" of the snack cake, according to a press release.
Josh Jans, Post's brand manager of cereal partnerships, said the company conducted "multiple consumer tests" to nail down the sweet flavor of Twinkies, which are cream-filled yellow sponge cakes. "We think fans will find that it not only tastes great with milk but also outside the bowl," he added.
Twinkies are one of the country's oldest and most recognizable snacks.
Created during the Great Depression, Twinkies were in production until 2012 when Hostess filed for bankruptcy and temporarily shuttered after struggling with high cost structures and slowing demand. The company was bought by private equity firms and reemerged with a smaller headcount called Hostess Brands. Gores Group bought a majority stake for $725 million in July 2016.
Post said that Twinkies "rank highest in consumer loyalty among Hostess brands." The cereal is the latest combination between Hostess and Post. The companies previously turned Hostess' Honey Bun and Donettes snacks into breakfast cereals.

Vlore is about 50NM south of Durres and is Albania's second largest port. The port itself lies about 5km from the centre of the town.
Position 40°26′ 58''N, 19°29′E.
See Albania Formalities for detailed Clearance Information.
On entering Albanian waters, call the Port Captain on their working channel of VHF 15 or on 16 (he speaks English).
Proceed to the main Vlore port.
Orikum Marina may also be able to deal with clearance formalities, contact the Manager in advance to confirm.
At Vlore Port, arriving yachts are directed to a berthing point on the commercial dock for clearing in (most likely alongside a tug), and requested to come to the official offices on shore, located between the two jetties, to deal with formalities. Clearance is required with Port Captain and Police.
Officials here do prefer you to use the services of an agent (50-60 Euros). See Albania Clearance Agents for details of the official Vlore agency.
Cruisers report that security here is poor and it is recommended to keep someone onboard when leaving the boat.
Last updated August 2015.
Vlore has a well-protected fishing harbour called Triport, now unfortunately badly silted up and impossible to enter by keel boat. It does not accept yachts. The entrance into nearby Vlore lagoon has also silted up, making access impossible.
Smaller than Durres, Vlore is busy with ferries to and from Italy and affords little shelter. Note that Vlore harbour is orientated around commerce with large rubber tyres as the harbour fenders on the commercial dock. Mooring here for clearance can be difficult due to the steel reinforcements which project from the piers. It is however possible to anchor off the ferry port in 5m off the East pier.
In southerly or Westerly winds, it would not be a good place to be for too long.
(photo from Orikum marina website)
The Orikum Marina, at the south end of the bay, comes recommended by cruisers. This is part of a new apartment/hotel complex. Entrance into the marina from the north is difficult to visualise as it look as though one is sailing towards a brutish concrete wall, and only a sharp turn to port at the last minute has the marina entrance opening up. It may be advisable to check the entrance out by dinghy first. There is a green flashing light on a pole at the head of the low breakwater and a red flashing light on a red buoy to mark the port side channel limit.
The entrance channel to the marina is reported to be 2.7-3.0m deep. The manager is called Luigi, and is an Italian.
There is a good, sandy anchorage just E of the lighthouse off the headland opposite.
There are restaurants on the beach within walking distance, but the small township for any provisioning is about 3km away.

I must preface this by noting that I have never used any 'hard' recreational pharmaceutical at all.
I started taking 5-HTP in an attempt to control severe insomnia. After cautiously starting at the recommended 2 x 50mg daily and finding absolutely no effects after 14 days, I started to gradually ramp up the dosage over a period of about 3 months until arriving at my current dosage of 2 x 100mg 4 times daily (800mg per day total). Even at this high dose I am finding it difficult to tell whether there are any effects at all! The most I can say is that perhaps my REM sleep (and therefore my dreaming intensity) has diminished slightly but otherwise there is no measurable effect at all. The insomnia is still more or less as it was.
I intend to persevere with this stuff but have somewhat unpleasant side effects.
Experience Reports are the writings and opinions of the individual authors who submit them.
Some of the activities described are dangerous and/or illegal and none are recommended by Erowid.

Implemented ‘John Conway’s Game of Life’ on NOKIA 3310 LCD screen, interfaced with ATmega8 micro controller
The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. The "game" is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. One interacts with the Game of Life by creating an initial configuration and observing how it evolves.

AWS::IoTSiteWise::AssetModel TumblingWindow
Contains a tumbling window, which is a repeating fixed-sized, non-overlapping, and contiguous time window. You can use this window in metrics to aggregate data from properties and other assets.
You can use m
, h
, d
, and w
when you
specify an interval or offset. Note that m
represents minutes, h
represents hours, d
represents days, and w
represents weeks. You can
also use s
to represent seconds in offset
.
The interval
and offset
parameters support the ISO 8601 formatPT5S
represents 5 seconds, PT5M
represents 5 minutes, and
PT5H
represents 5 hours.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
Properties
Interval
-
The time interval for the tumbling window. The interval time must be between 1 minute and 1 week.
AWS IoT SiteWise computes the
1w
interval the end of Sunday at midnight each week (UTC), the1d
interval at the end of each day at midnight (UTC), the1h
interval at the end of each hour, and so on.When AWS IoT SiteWise aggregates data points for metric computations, the start of each interval is exclusive and the end of each interval is inclusive. AWS IoT SiteWise places the computed data point at the end of the interval.
Required: Yes
Type: String
Update requires: No interruption
Offset
-
The offset for the tumbling window. The
offset
parameter accepts the following:-
The offset time.
For example, if you specify
18h
foroffset
and1d
forinterval
, AWS IoT SiteWise aggregates data in one of the following ways:-
If you create the metric before or at 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) on the day when you create the metric.
-
If you create the metric after 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) the next day.
-
-
The ISO 8601 format.
For example, if you specify
PT18H
foroffset
and1d
forinterval
, AWS IoT SiteWise aggregates data in one of the following ways:-
If you create the metric before or at 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) on the day when you create the metric.
-
If you create the metric after 6 PM (UTC), you get the first aggregation result at 6 PM (UTC) the next day.
-
-
The 24-hour clock.
For example, if you specify
00:03:00
foroffset
,5m
forinterval
, and you create the metric at 2 PM (UTC), you get the first aggregation result at 2:03 PM (UTC). You get the second aggregation result at 2:08 PM (UTC). -
The offset time zone.
For example, if you specify
2021-07-23T18:00-08
foroffset
and1d
forinterval
, AWS IoT SiteWise aggregates data in one of the following ways:-
If you create the metric before or at 6 PM (PST), you get the first aggregation result at 6 PM (PST) on the day when you create the metric.
-
If you create the metric after 6 PM (PST), you get the first aggregation result at 6 PM (PST) the next day.
-
Required: No
Type: String
Update requires: No interruption
-

Flying back from a nice 2 week vacation in Texas & I had a chance to think about primative operators. Specifically in this post I’ll be exploring what a primative opeartor actually is and whether there’s such a thing as “more powerful” primatives.
To get started I’ll be working with mapa function we all hold near and dear. Map’s signature takes a value of some type A and a function A => B. So the full signature would be:
def map[A, B](x: A)(f: A => B) : B
This function has as it’s range and domain all possible morphisms across two types. For instance, based on signature alone map can transform an Int into a Dinosaur via some magical function f(i: Int). However, what it cannot do is transform an Int and a String into a Dinosaur. You could accomplish this via a Tuple[Int, String] and an f(t: (Int, String)) but because you are still acting on a single parameter you’re unable to partially apply map to the tuple. Really this means we’ve been forced into evaluating all or none of the parameters with no ability to choose between them. That seems like an unnecessary constraint for a morphism.
This suggests there exists some more “powerful” version of map that allows us to partially apply across multiple parameters and evaluate them independently. For lack of a better name lets call this map2. Map2 accepts two types of parameters & returns a third, so we know it’s signature looks like this:
def map2[A,B,C](a: A, b: B)(f: (A, B) => C): C
Map2 is able to handle anything map can do by providing a no-op type as B’s type argument. For example, here’s map implemented via map2:
def map[A, B](a: A)(f: A => B): B =
map2(a, NoOp)((x, y) => f(x))
This on it’s own buys us alot of power because we no longer need to worry about actually applying the computation for the morphism in map, instead we can defer it into map2. The next question I have about Map2 is whether we can create a function Map3 that is again more powerful than Map2? Logically it would seem that since Map2’s domain and range are strictly supersets of the domain and range for Map that it holds Map2 should be a subset of Map3, right?
It turns out this isn’t quite the case on the implemetation level. You can actually implement all other arity mapping functions in terms of Map2 by using a trick simmilar to have a right fold operates. That is to say via building up a chain of function calls to provide the proper arity. Here’s Map3:
def map3[A, B, C, D](a: A, b: B, c: C)(f: (A, B, C) => D): D =
map2(a, b)((x, y) => map2(c, NoOp)(f(a, b, c)))
This ends up creating a chain of map2 calls that can be composed together as f • g • … to generate the full chain.
As I think about it, it is actually possible to use the same approach to construct a similarly deep function call chain for map, allowing us to use map as the base primative and implement all other arity map’s in terms of the base primitive.
With standard Map it’s still impossible to use a single function call to support >1 parameter, where as map with arity > 1 inherently supports this
I’ll update this post once I’ve had a chance to do some more research on which of the two functions is actually the base primitive..


Abstract
During both the 2015 and 2019 federal election, the Conservatives remain to be the most distrusted party according to the Canadian Election Study data. After four years of Liberals in power, more and more Canadians are dissatisfied with the party’s leadership, especially for Albertans and Saskatchewanians.
Introduction
Election surveys always attract social scientists’ interests. Scholars try to use surveys to guide predictions of election results. For whom people will vote? It seems to be the ultimate question in any survey study. However, sometimes, people are reluctant to reveal their real picks. Interestingly, they are less likely to lie on who they dislike. That’s why this report will take a look at which party people said they would not vote. The results are quite interesting as we can identify some distinctive regional patterns. It is also clear to see how people changed their minds after an election cycle. The analysis itself may not provide enough information on why the regional discrepancy exists. However, it could remind us that people living in different parts of this country have different needs and concerns.
In this analysis, we make two kinds of comparison. We first parallelly compare the data among provinces in the same election - the 2019 federal election and the 2015 election. Then we examine the change of voters’ attitudes from 2015 to 2019.
It is worth mentioning that the result could not serve as evidence to make any causal assertion. Instead, it flags the federal government’s policy issues in dealing with regional affairs, and it is inspiring for political scientists working on public policy study.
Data
The Canadian Election Study (CES) is a series of large-scale surveys that have been conducted prior, and immediately after, each Canadian federal election since 1965. The purpose of CES is to document the attitudes of Canadians during and after each election. (Stephenson et al., 2020) The dataset used in this article is a subset of CES, which only contains the online survey of the 2019 Canadian federal election and a combination of web and phone surveys from the 2015 election. In both cases, we use only the campaign period data.
The original dataset is giant with more than 600 variables, each representing a question in the survey. Here we will only focus on responses to the question: are there any parties that you would absolutely not vote for? We filter out all non-responses and keep the ones with meaningful answers only. The dataset shrinks to having only five variables: the year of birth of the respondents, the gender, the education, the province of residence, and the party which the respondent considers not going to vote for. Though this article will only make extensive use of the province and the voting attitude data, the other variables are included to hint at possible biases during the data collection.
Discussion
Before proceed reading, it is necessary to emphasize the limitations of this analysis, especially the ones due to the lack of data. During the data cleaning process, the size of the two datasets has been dramatically shrunk. At the final stage, the 2015 data contains only 87 observations, and the 2019 dataset has only 97 entries, which reduces the credibility of this analysis. But the results could still offer some insights.
We first take a look at the 2015 data. One obvious thing is that people living in Nunavut seems really don’t like the Conservatives, given that the party receives a 100% vote. However, if we examine the data a bit closer, we realize that there is only one participant in Nunavut. The only one happens to disapprove of the Conservatives very much, so at least in 2015, Nunavut’s data is not reliable. The same issue also exists in Northwest Territories and Yukon’s 2015 data. Things got a bit better in 2019. We have more participants in 2019’s data. During the 2019 federal election, the Conservatives and the NDP are Nunavut people’s two most distrusted parties.
Another interesting observation is about the change in people’s attitudes. The plots imply that after four years under the Liberal Party, the dissatisfaction level of the Liberals increases in almost all provinces. The trend is most evident in Alberta and Saskatchewan. The results seem to be consistent with the news about Western Canadian provinces complaining about the federal government’s neglect.
Overall, during both elections, the Conservatives are the most distrusted party in all provinces.
Weaknesses and next steps
We have talked a lot about the worrying quality of the datasets so far. The small sample size limits how much credible information the dataset could provide us. In addition to the sample size, there are some other issues in the data collection phase. One of them is the different interpretations of survey questions. For example, in the 2019 survey, only people living in Quebec can choose Bloc Quebecois. However, in 2015, this restriction did not apply. In future studies, more careful criteria should be developed to address these differences. Moreover, a carefully designed weight scheme is necessary to reflect population-wide attitudes better.

BEAUTY AND THE BEAST A film review by Frank Maloney Copyright 1991 Frank Maloney
BEAUTY AND THE BEAST is a Walt Disney animated musical film. The directors are Gary Trousdale and Kirk Wise. The voices are provided by Paige O'Hara, Robby Benson, Angela Lansbury, Robert White, Jerry Ohrbach, and David Ogden Stiers. The songs were written by the late Howard Ashman and Alan Menken, the same team responsible for THE LITTLE MERMAID and THE LITTLE SHOP OF HORRORS. Rated G - General audiences.
BEAUTY AND THE BEAST ranks with the best that Disney ever produced, either before or after Walt's death. It is, I'm sure, better than MERMAID, despite similarities and parallels. For one thing, Belle (voice by Paige O'Hara) is a more interesting character than Ariel. Belle's goal in life to get out of her stifling provincial village, not to get married; indeed, the only marriage prospect in sight is so unacceptable as to rule out the possibility altogether. That suitor is Gaston (voice of Robert White) is the hilariously conceited village macho man, who thinks Belle's beloved books are fit only to cushion his muddy hunting boots. Belle is independent, bookish, the perfect personality to learn to see past the cover of the Beast's book, as it were.
The voice of the Beast is done by Robby Benson, of all people, who can roar, inject great humor into the beastly mutterings, and be tender, hurt, and loving. Other voice characters include Mrs. Potts (Angela Lansbury), a living teapot and as cozy, nurturing a teapot as ever poured itself; Lansbury, by the way, sings the title song, sounding rather like a cross between the cook in "Upstairs, Downstairs" and the estimable Verna Felton, the voice of the fairy godmother in CINDERELLA. Jerry Ohrbach did the voice of Lumiere, the candelabra (natch), and David Odgen Stiers the clock, Cogsworth. At first blush, one might think, as I did watching trailers for this film earlier this fall, anthropomorphized bric-a-brac was more than a little too cute. But instead, I was charmed by them and amazed at how thoroughly personalized they were.
In fact, looking at the above voice cast, one is struck by the quality overall. The Broadway musical is alive and well in the cartoon and this is a dream cast that no producer could pay enough to appear live on stage for a year. The music is excellent and quite different from the score of MERMAID. Only one big production number, no ethnic overtones. Instead, operetta-like songs and numbers, including a classic curtain raiser that gets a lot of characters singing together and antiphonally. The influence of Andrew Lloyd Webber is there to some degree and they add to the development of the characters.
The script is funny, exciting, resonant, and entertaining to the kids and the adults. The animation is very imaginative and detailed. The Beast's castle is a masterpiece of Gothic brooding. The animators used a multiplane camera and some rather flashy computer animation, especially in the ballroom scene that seemed to approach photorealism at moments. The story opens with a prologue told by a voice-overs and stained-glass-like illustrations, a motif we return to at the end. The story-telling is clear, precise and uses state-of-the-art techniques to advance the story.
I can cheerfully recommend BEAUTY AND THE BEAST to you at full prices.

Network is the fifth and final section in scouting. Crouch valley's local & only Network group is Valley Network and it's for scouts between the age of 18-25 years old. We meet every Monday evening & are based at Ark Lane campsite.
The Network section focuses on community, international & adventure. Our program is youth led and is fairly similar to the Explorer Scout's activities however it can be even more flexible and/or adventurous due to our age range. Our section allows you to continue or start awards like the Queen's Scout Award, the Explorer Belt, the Scout of the World Award & DofE award. We still have regular camps whether is be a National Network Event like Gathering (a wonderful camp in the Lake District) or large international events like the World Scout Moot (2017 was in Iceland) .
Week to week, we may get involved with bowling, climbing, skating, wide games, cooking, walks, the cinema, quizzes etc but where it's youth led, if people have a realistic idea then they can run that evening's activity. Overall, It's a social & relaxed section and you can make it your own.
