"The Tailor of Panama" is a different kind of spy movie. Despite the presence of Pierce Brosnan, there is nary a hint of James Bond flash here. Instead of big action scenes, leering super villains and empty-headed femme fatales, we get interesting characters and an intriguing situation. Based on the novel by John le Carré, who also co-wrote the screenplay, the film offers viewers something rarely seen in theaters this time of year: a solid, well-told story.
Brosnan plays Andy Osnard, a British operative walking on thin ice. His British superiors ship him off to Panama, making sure he understands that he had better not screw up the placement. Osnard arrives in the tropics virtually oozing contempt for his new co-workers and his new home base. When shown the Bridge of the Americas by a person marveling over the fact that, since the creation of the Panama Canal, the structure is the sole connection between North and South America, he barely keeps from yawning. Brosnan clearly relishes the chance to be the antithesis of 007, investing the suave spy with a distinct reptilian quality coupled with an air of indifference that irks his fellows to no end.
Searching for a way to get information on the government, Osnard sets his sights on Harry Pendel (Geoffrey Rush), an unctuous tailor serving the Panamanian elite. Harry claims to be a transplant from Britain's renowned Saville Row, but Osnard knows his secret: The tailor is an ex-con who served five years in prison after torching his uncle's shop in an insurance scam. He also knows that Harry is up to his ears in debt, having spent a fortune on an unsuccessful farm.
Osnard offers Harry a way out. He will pay for information Harry has gathered from his upscale clientele. Eager to comply, Harry offers what he knows, then starts concocting tidbits to keep the money flowing. Before long, he is forced to spy on his loving wife, Louisa (Jamie Lee Curtis), an aide to the Canal director.
 Osnard turns in reports about the "silent opposition," a group threatening to upset the balance of control over the canal. The bogus revelation proves explosive, leading to meetings in Washington D.C. over how to best protect the vital waterway. Meanwhile, Osnard wallows in his newfound status, enjoying the best the city has to offer and wooing an attractive co-worker. And Harry grows ever more fretful, fearing the consequences if his clients, not to mention his wife, learn about his lies.
Geoffrey Rush is wonderful as Harry, fawning over his customers by day and savoring his rich family life in the evenings, all while playing secret agent in the off hours with his new benefactor. Rush makes Harry a credible figure, presenting the various levels of the character so effectively that he remains sympathetic despite his duplicity. After gaining fame playing larger than life characters, Rush flips everything around for this role, using his energy to depict the quiet desperation of a man slowly realizing that the solution to his troubles may be worse than the original problems.
Although she gets far too little screen time, Jamie Lee Curtis imbues Louisa with a depth greater than the screenplay provides her. Of the central characters, she is the only one that exhibits maturity and genuine self-confidence. Curtis is one of my favorite female actors; whiplash smart, sultry and charismatic, she deserves more than supporting roles.
Speaking of supporting characters, there are some great ones here. Harold Pinter is amusing as Harry's Uncle Benny, who pops up throughout the story in a number of creative ways. Also shoring up the proceedings is Jon Polito as a corrupt banker and Dylan Baker, who is a riot as a United States general straight out of the Dr. Strangelove school of armed patriotism.
But the most important secondary performers are Leonor Varela and Brendan Gleeson, both outstanding as two wounded activists. Their presence adds weight to the story, reminding us that beyond the charades of the leading men, there are real people that have suffered greatly over the politics connected to the Canal. Director John Boorman adds additional verisimilitude by shooting the film on location. Instead of using Panama City merely as a colorful backdrop, he adroitly weaves in footage of all aspects of life there. The metropolis, described by one character as "Casablanca without heroes" pulsates with life, underling the folly of the two foreigners playing dangerous games that could have a disastrous impact on a great many people. "The Tailor of Panama" succeeds because the principals behind it were bright enough to make it more than a simple entertainment.

BLAST FROM THE PAST by DeWyNGaLe Rating: B
Brendan Fraser is the star of this nutty new comedy, which tries to be like the 1997 smash, Austin Powers. Fraser plays Adam, a boy who has lived underground with his parents, played by Sissy Spacek and Christopher Walken, all of his life. His dad built a world underground in case a nuclear strike were to occur, and he believes that the strike has occurred and they must go underground for the next thirty years. While underground, their son Adam is born. He must live in a limited world, not knowing what the sky or other people looked like. Now, after a long thirty years, it is time for Adam to see the world.
The scenes underground with Adam's parents are very nicely done and are absolutely hysterical. Unfortunately, they don't last for long, and Spacek and Walken's performances are extremely limited. Unlike Austin Powers, Adam has never been out in the real world before, so it will be a total surprise to him. Before setting foot in the real world, he makes a wish that he could meet a girl. His wish is about to come true. When Adam was finally able to come out of the underground cell, the movie goes downhill. Once Adam comes above ground, Alicia Silverstone is the only thing saving the film from completely collapsing. A corny plot line withing the plot is the shop above where the cell has been built. When the workers in the shop above see Adam, they think he is from a different race, which I thought could have been cut from the film entirely. To make some money, Adam decides to sell some of his father's baseball cards. At the baseball card shop he meets Eve, played by Alicia Silverstone. She is very confused about the ignorance of Adam.
Following the tradition of romantic comedies, Adam and Eve fall in love and then when everything is going just right, something bad happens. Luckily in Blast From The Past, there are a few more twists to make the same old plot line a little more fun to watch. Spacek and Walken as the parents were the best part of the film, and the stole the show. Silverstone gives a lot better performance than in her latest films, but she doesn't surpass her outstanding, one of a kind performance in Clueless. Fraser's character of Adam is a little overdone, and quite annoying at times. He is still a pretty likable character though.
The relationship between Adam and Eve doesn't go anywhere, and it doesn't seem like the two characters bond well. As Eve takes Adam out to more and more places, he becomes interested in more things, including other girls. Eve is very disappointed, but she won't give up Adam. After Adam tells her the story about how he lives underground, she thinks he is crazy and she tries to admit him to the mental institution. This is probably the most humorous part of the film. A very predictable ending occurrs, which is very disappointing to me. It would be nice for once for a film to have a funny, surprising ending, but Blast From The Past disappoints me once again.
The scenes in Blast From The Past are a little humorous, but nothing more than that. That's pretty much how the whole film is. It isn't great or a classic, but it isn't meant to be. It is a feel good, enjoyable movie that is fun to watch. It could have been taken further, to a higher level of comedy. The key to that would have been to add more scenes with Spacek and Walken.
The Bottom Line- Just your average romantic comedy.

The Journey to Invisible Authentication
There is little to no doubt that passwords are on their way out of use and relevance with more advanced solutions taking over the market. But no matter what comes next, the most advanced solutions that are increasingly gaining attention and traction are making one major change in ensuring cybersecurity – they introduce invisible, non-interrupting methods of continuous authentication.

Datetime Patterns for Formatting and Parsing
There are several common scenarios for datetime usage in Spark:
-
CSV/JSON datasources use the pattern string for parsing and formatting datetime content.
-
Datetime functions related to convert
StringType
to/fromDateType
orTimestampType
. For example,unix_timestamp
,date_format
,to_unix_timestamp
,from_unixtime
,to_date
,to_timestamp
,from_utc_timestamp
,to_utc_timestamp
, etc.
Spark uses pattern letters in the following table for date and timestamp parsing and formatting:
| Symbol | Meaning | Presentation | Examples |
|---|---|---|---|
| G | era | text | AD; Anno Domini |
| y | year | year | 2020; 20 |
| D | day-of-year | number(3) | 189 |
| M/L | month-of-year | month | 7; 07; Jul; July |
| d | day-of-month | number(3) | 28 |
| Q/q | quarter-of-year | number/text | 3; 03; Q3; 3rd quarter |
| E | day-of-week | text | Tue; Tuesday |
| F | aligned day of week in month | number(1) | 3 |
| a | am-pm-of-day | am-pm | PM |
| h | clock-hour-of-am-pm (1-12) | number(2) | 12 |
| K | hour-of-am-pm (0-11) | number(2) | 0 |
| k | clock-hour-of-day (1-24) | number(2) | 0 |
| H | hour-of-day (0-23) | number(2) | 0 |
| m | minute-of-hour | number(2) | 30 |
| s | second-of-minute | number(2) | 55 |
| S | fraction-of-second | fraction | 978 |
| V | time-zone ID | zone-id | America/Los_Angeles; Z; -08:30 |
| z | time-zone name | zone-name | Pacific Standard Time; PST |
| O | localized zone-offset | offset-O | GMT+8; GMT+08:00; UTC-08:00; |
| X | zone-offset ‘Z’ for zero | offset-X | Z; -08; -0830; -08:30; -083015; -08:30:15; |
| x | zone-offset | offset-x | +0000; -08; -0830; -08:30; -083015; -08:30:15; |
| Z | zone-offset | offset-Z | +0000; -0800; -08:00; |
| ‘ | escape for text | delimiter | |
| ’‘ | single quote | literal | ’ |
| [ | optional section start | ||
| ] | optional section end |
The count of pattern letters determines the format.
-
Text: The text style is determined based on the number of pattern letters used. Less than 4 pattern letters will use the short text form, typically an abbreviation, e.g. day-of-week Monday might output “Mon”. Exactly 4 pattern letters will use the full text form, typically the full description, e.g, day-of-week Monday might output “Monday”. 5 or more letters will fail.
-
Number(n): The n here represents the maximum count of letters this type of datetime pattern can be used. If the count of letters is one, then the value is output using the minimum number of digits and without padding. Otherwise, the count of digits is used as the width of the output field, with the value zero-padded as necessary.
-
Number/Text: If the count of pattern letters is 3 or greater, use the Text rules above. Otherwise use the Number rules above.
-
Fraction: Use one or more (up to 9) contiguous
'S'
characters, e,gSSSSSS
, to parse and format fraction of second. For parsing, the acceptable fraction length can be [1, the number of contiguous ‘S’]. For formatting, the fraction length would be padded to the number of contiguous ‘S’ with zeros. Spark supports datetime of micro-of-second precision, which has up to 6 significant digits, but can parse nano-of-second with exceeded part truncated. -
Year: The count of letters determines the minimum field width below which padding is used. If the count of letters is two, then a reduced two digit form is used. For printing, this outputs the rightmost two digits. For parsing, this will parse using the base value of 2000, resulting in a year within the range 2000 to 2099 inclusive. If the count of letters is less than four (but not two), then the sign is only output for negative years. Otherwise, the sign is output if the pad width is exceeded when ‘G’ is not present. 7 or more letters will fail.
- Month: It follows the rule of Number/Text. The text form is depend on letters - ‘M’ denotes the ‘standard’ form, and ‘L’ is for ‘stand-alone’ form. These two forms are different only in some certain languages. For example, in Russian, ‘Июль’ is the stand-alone form of July, and ‘Июля’ is the standard form. Here are examples for all supported pattern letters:
'M'
or'L'
: Month number in a year starting from 1. There is no difference between ‘M’ and ‘L’. Month from 1 to 9 are printed without padding.spark-sql> select date_format(date '1970-01-01', "M"); 1 spark-sql> select date_format(date '1970-12-01', "L"); 12
'MM'
or'LL'
: Month number in a year starting from 1. Zero padding is added for month 1-9.spark-sql> select date_format(date '1970-1-01', "LL"); 01 spark-sql> select date_format(date '1970-09-01', "MM"); 09
'MMM'
: Short textual representation in the standard form. The month pattern should be a part of a date pattern not just a stand-alone month except locales where there is no difference between stand and stand-alone forms like in English.spark-sql> select date_format(date '1970-01-01', "d MMM"); 1 Jan spark-sql> select to_csv(named_struct('date', date '1970-01-01'), map('dateFormat', 'dd MMM', 'locale', 'RU')); 01 янв.
'LLL'
: Short textual representation in the stand-alone form. It should be used to format/parse only months without any other date fields.spark-sql> select date_format(date '1970-01-01', "LLL"); Jan spark-sql> select to_csv(named_struct('date', date '1970-01-01'), map('dateFormat', 'LLL', 'locale', 'RU')); янв.
'MMMM'
: full textual month representation in the standard form. It is used for parsing/formatting months as a part of dates/timestamps.spark-sql> select date_format(date '1970-01-01', "d MMMM"); 1 January spark-sql> select to_csv(named_struct('date', date '1970-01-01'), map('dateFormat', 'd MMMM', 'locale', 'RU')); 1 января
'LLLL'
: full textual month representation in the stand-alone form. The pattern can be used to format/parse only months.spark-sql> select date_format(date '1970-01-01', "LLLL"); January spark-sql> select to_csv(named_struct('date', date '1970-01-01'), map('dateFormat', 'LLLL', 'locale', 'RU')); январь
-
am-pm: This outputs the am-pm-of-day. Pattern letter count must be 1.
-
Zone ID(V): This outputs the display the time-zone ID. Pattern letter count must be 2.
-
Zone names(z): This outputs the display textual name of the time-zone ID. If the count of letters is one, two or three, then the short name is output. If the count of letters is four, then the full name is output. Five or more letters will fail.
-
Offset X and x: This formats the offset based on the number of pattern letters. One letter outputs just the hour, such as ‘+01’, unless the minute is non-zero in which case the minute is also output, such as ‘+0130’. Two letters outputs the hour and minute, without a colon, such as ‘+0130’. Three letters outputs the hour and minute, with a colon, such as ‘+01:30’. Four letters outputs the hour and minute and optional second, without a colon, such as ‘+013015’. Five letters outputs the hour and minute and optional second, with a colon, such as ‘+01:30:15’. Six or more letters will fail. Pattern letter ‘X’ (upper case) will output ‘Z’ when the offset to be output would be zero, whereas pattern letter ‘x’ (lower case) will output ‘+00’, ‘+0000’, or ‘+00:00’.
-
Offset O: This formats the localized offset based on the number of pattern letters. One letter outputs the short form of the localized offset, which is localized offset text, such as ‘GMT’, with hour without leading zero, optional 2-digit minute and second if non-zero, and colon, for example ‘GMT+8’. Four letters outputs the full form, which is localized offset text, such as ‘GMT, with 2-digit hour and minute field, optional second field if non-zero, and colon, for example ‘GMT+08:00’. Any other count of letters will fail.
-
Offset Z: This formats the offset based on the number of pattern letters. One, two or three letters outputs the hour and minute, without a colon, such as ‘+0130’. The output will be ‘+0000’ when the offset is zero. Four letters outputs the full form of localized offset, equivalent to four letters of Offset-O. The output will be the corresponding localized offset text if the offset is zero. Five letters outputs the hour, minute, with optional second if non-zero, with colon. It outputs ‘Z’ if the offset is zero. Six or more letters will fail.
-
Optional section start and end: Use
[]
to define an optional section and maybe nested. During formatting, all valid data will be output even it is in the optional section. During parsing, the whole section may be missing from the parsed string. An optional section is started by[
and ended using]
(or at the end of the pattern). - Symbols of ‘E’, ‘F’, ‘q’ and ‘Q’ can only be used for datetime formatting, e.g.
date_format
. They are not allowed used for datetime parsing, e.g.to_timestamp
.

Programming has always been, in my mind, a superpower. When the whole class was asked this question, I sincerely thought everyone would think this to be true. I look up to those who can write great code because God knows I struggle to write some myself. It’s my fourth year as a computer science student and I still feel intimidated when I walk into my classes because I know my classmates will be developing software that will keep on eating the world. As you might have guessed, I don’t consider myself a great coder (maybe not even a good coder) but I love this major because, like Jeff Atwood said
Software can also encourage people to do better things and help others.
This is the type of power that I feel programmers have, and the reason I wanted to be able to code myself in the first place.
Growing up catholic and coming to discover my own faith even more while at Notre Dame I reconfirmed by desire to give back as much as I can to the people around me. The very reason I am at Notre Dame is because my whole family struggled greatly to give me an opportunity none of them even dreamed of having when they were younger. Coming here I knew I had to study something that made my heart beat faster (and programming quite literally does sometimes when my crappy code actually compiles), but more so that could give me a toolset to be able to help others.
Software development, without a doubt, has empowered me. However, it has also given me a huge burden. I feel a tremendous responsibility to do something meaningful with this superpower, and I haven’t yet. Part of me thinks that by hiding behind the thought of not being a good enough coder I have relieved myself of this fear of not living up to my own expectations. This means I haven’t taken risks I wish I had to try and actually become the “superhero” a younger me would be proud of. I feel tormented because I have hidden my talents and never put my money on the table out of my own fear. To this day I work to change this mindset day by day.
Because I feel so strongly about the great responsibility and obligation that comes with this superpower, I find the different frameworks we read about and debated in class essential to this line of work. It can be tough to think about the very difficult situations that can arise with ethical dilemmas, especially in programming. No one guidebook or framework will tell you exactly what the best course of action is in a difficult situation— maximize good over bad? Focus on the intention of the action? On the consequences alone? It can be hard!
It has been a slow and challenging journey for me to continuously strive to be a better person. However, I truly believe that I work every day to become the type of woman I looked up to when I was a girl, and that my best and most ambitious project— my life— would make my parents proud. When I think about the tough ethical dilemmas I have had to face in my short 21 years, I realize that most of the time I come back to them— my family and young me— and reflect on how they would feel about my decision. Would they be proud? I say most of the time because there have been situations when I forget to stop and reflect and have made the wrong choices. Nevertheless, even after the worst situations pass, I come back to them again and hope that I can make a better choice in the future.

Euclidean domains are extending integral domains, but the entire file doesn't use this. We could just as well extend comm_ring
. @Kevin Buzzard Do you know if every Euclidean ring is automatically an integral domain?
I think the following theorems imply they are
lemma mul_div_cancel (a) {b : α} (b0 : b ≠ 0) : (a * b) / b = a := by rw mul_comm; exact mul_div_cancel_left a b0 @[simp] lemma zero_div {a : α} (a0 : a ≠ 0) : 0 / a = 0 := by simpa only [zero_mul] using mul_div_cancel 0 a0
Good catch!
Chris and Lean helped me prove a theorem!
Wait, I was wrong. There's no way to prove zero_ne_one
.
Both a theorem, and a counterexample :slight_smile:
Haha, sure. Zerology bites me again.
Maybe it should extend nonzero_comm_ring
instead.
Wouldn't that create a possibility for diamonds? Say we prove that integral closures are integral domains. And then for certain of those we prove that they are euclidean rings.
Maybe we should just have euclidean.core
and then of_core
... that seems to be a common trick.
Yes, but they would be definitionally equal diamonds, which happen all the time and are fine.
Why would they be defeq? Because integral_domain
extends comm_ring
by a Prop
?
But all the fields would be the same, because they all come from the same place ultimately.
No we would have two different proofs that certain rings are integral domains...
One coming from the fact that it's an integral closure, the other from the fact that it is a euclidean ring
Proofs are irrelevant.
The same thing happens with say, polynomials over an integral domain are an integral domain which means they're a ring, but polynomials over a ring are a ring. So there's two different paths, but they're defeq.
Ok, good.
This worked when I tried changing integral domain.
example : euclidean_domain.integral_domain ℤ = linear_ordered_comm_ring.to_integral_domain := rfl
Great!

The term Ides
of March, March
15th, is
best known as the date on which Julius Caesar was killed in 44
B.C. Caesar was stabbed (23 times) to death in the Roman Senate
by a group of 60 other co-conspirators led by Marcus Junius
Brutus and Gaius Cassius Longinus. We did not have that much
excitement but between Derek's birthday and the end of the
George Town Cruiser Regatta we kept busy.
The end of the Regatta saw the mighty sand sculpture and the
volleyball tournament. Derek participated with two other boats
and made a large sea turtle that took 1st place. It was a
good 10 feet long and 5 feet wide. Dean
tried his hand in volleyball and while he had fun his team did
not do as well as Derek's. The Regatta kept the area
hopping with events and cruisers participation. After the
Regatta many boats started their travels onward so the anchorage
has fewer boats now. Dean's brother and family are due in
the 1st week of April so after their visit it will be time for
our exit as well.
Derek's 12th birthday came on the 13th so Kris arranged for a group
of the kids get together and also made a cake. This was the first
birthday
we had issues of sand getting into the food.
Derek's big birthday gift was to go scuba diving. A
local dive shop offers a introductory dive for beginners and
Derek was able to use all the equipment and go down 20 feet.
All in all he was in the water for a good 45 minutes and now
wants more time in the water.
The weather has continued to be very mild, the days in the mid
70s to low 80's and the nights high 60s. We talked to a
local who said the water will warm up from the current 72 to low
80s during the summer.
Update; 03/22/12 the Ides of March, or close to it and Dereks Birthday

Everything you'll ever need to know about Disney+

Finally. The most anticipated streaming service is here. Home to not just Star Wars, the Marvel Cinematic Universe, and all your Pixar favorites, but educational entertainment like National Geographic and storied series like The Simpsons. Oh, and all the Disney movies and TV shows you could ever want to watch.
Welcome to Disney Plus (Disney+).
A magical streaming service
Disney+
All your Disney favorites, and so much more
From DCOMs to National Geographic, from Marvel to Lucasfilm to 20th Century Fox and beyond, Disney+ delivers a streaming service for all ages.

What is Disney Plus?
Disney+ is a streaming service that brings together all of the content in Disney's massive media empire — from Disney/Pixar to Marvel to Lucasfilm to National Geographic and 20th Century Fox — in one easy-to-use app. Available on most major platforms and with hundreds of films and TV shows from the Disney Vault and recent theatrical releases, Disney+ is a tantalizing realization of a dream many Disney nerds (like myself) have had of being able to watch their favorite shows and films in one place rather than having to hunt for them across a half dozen services — and this is also the first time a great deal of television content Disney has produced is available for streaming.
In short, Disney+ is awesome.
This is the future of video for Disney. Anything and everything that falls under the Disney umbrella — and make no mistake, it is a huge umbrella — will go through the Disney+ app, on whatever platform you wish to watch it on. If that sounds impossibly big, well, you're right. But Disney has done well to pave this road with the also extremely successful ESPN+, which also is owned by Disney and runs on the same technology. (In fact, Disney bought the company that built the streaming side of things.)
The best part of Disney+ is that it is ridiculously easy to sign up for the service whether you're at your desktop computer or on the go with your phone. It takes less than a minute to sign up for your free trial and there's no silly onboarding app to try and jump start your recommendations or watchlist.
Where is Disney Plus available?
Disney+ launched in Canada, the Netherlands, and the United States on November 12 and launched in Australia and New Zealand on November 19. Disney plans to launch Disney+ globally in dozens of countries over the next two years, but it's going to take a while. The tentative timeline for the global rollout right now is:
- March 31, 2020: United Kingdom, France, Italy and Spain
- First half of 2020: Other western European countries
- First half of 2021: Eastern European countries
- Throughout 2020-2021: Asia-Pacific countries
- First half of 2020: Latin America
If you don't live in a country where Disney+ has launched and you're too impatient to wait for it to come to your own market, there's still an option, but you're going to have to jump through a few hoops, namely using a VPN to pretend you live in a country where Disney+ is available.
Can I watch Disney Plus through a VPN?
Yes, using a VPN, you can create a new Google Play or Apple account — or switch your current account to a US/Netherlands/Canada account — and add your credit card with a US zip code. It's then possible to sign up for Disney+ with payment being done through Google Play or Apple.
You'll have to use a VPN to watch on any and every device you watch Disney+ through if you do go through with this method, which can be tricky on some smart TVs. You'll also have to remember to turn the VPN on and off when you're not watching if you don't want it interfering in other accounts and services on your phone or laptop.
What devices support Disney Plus?
Disney+ is available on quite a few devices at launch, but it's not as universally available as Netflix — yet. Whether you're on a phone, laptop, TV or gaming console built in the last 3 years, chances are Disney+ is available right now or will be available soon.
Mobile devices
Source: Disney+
Disney+ is available on Android phones and tablets, as well as Apple iPhones and iPads. The benefit of using Disney+ on a phone or tablet rather than watching on a smart TV is that on these devices you can download videos for offline playback, which is something you can do on up to 10 devices per Disney+ account, meaning everyone on the plan can keep a few videos downloaded in case of emergencies like being trapped on a Wi-Fi-less flight.
Desktop and laptop computers
Like all modern streaming services, Disney+ allows you to stream directly from DisneyPlus.com on Windows and MacOS computers (sorry, Linux). You can't download videos for offline playback when streaming through the browser, but you do have some handy keyboard controls.
While the Disney+ help page says that Chromebook browsers aren't supported — and back during the initial beta test in the Netherlands, they weren't — streaming through the Chrome browser has worked on every Chromebook I've tried so far after a timeout error on the initial DRM check. Chromebooks are also the only laptops that can download videos for offline playback because Chromebooks also use they can use the Android app via Google Play.
It's rather unfortunate that Disney didn't release a Universal Windows Platform (UWP) app, especially since in order to release an Xbox One app, they've already done most of the work needed to make one. Since 4K streaming isn't currently supported when streaming through the website, a UWP would be a great way to allow Windows 10 media PCs to stream Disney+ in UHD.
Consoles
Most people want to stream on a bigger screen so that they can enjoy Disney+ with their friends and family, and that means that supporting the gaming and entertainment consoles that we use now more than ever. Support for Android TV and Roku devices was announced from the first Disney+ presentations back in April, along with support for Google Chromecast and for Apple TV, but the main holdout was Amazon Fire TV. After months of negotiations with Amazon, support for Fire TV devices was announced just days before the public launch of Disney+.
On the gaming console side, both the PlayStation 4 series and Xbox One series are supported right now, and the upcoming PS5 and Xbox Scarlett are expected to be supported when they launch next year. I honestly believe that gaming consoles are the best for watching Disney+ because you can use your controller triggers to fast forward and rewind more easily than using the on-screen controls.
On the mobile console side of the equation, no mobile consoles are currently supported, although Disney has hinted at bringing Disney+ to Nintendo Switch in the future. We have no concrete timeline on when it could launch on Switch, but hopefully it won't take too long.
Smart TVs
Smart TVs is one area where Disney+ has somewhat limited support at the moment. Only a handful of Smart TVs have Disney+ apps at the moment:
- LG TVs running Web OS 3.0 produced in or after 2016
- Samsung TVs running Tizen OS produced in or after 2016
- Sony TVs running Android TV
Beyond these brands, there's support for TVs that run Android TV, Amazon Fire TV, or Roku TV through their respective app stores. This is great news because you can't stream Disney+ through browsers on Smart TVs.
Most TVs with Chromecast built-in or Apple AirPlay built in can play Disney+ content streamed via the Disney+ app on Android or iOS. The outlier to this support is Vizio TVs, which have an outdated, unsupported version of Chromecast built-in on them. AirPlay still works on Vizio TVs, but Android users will need to buy a standalone Chromecast that is being properly updated by Google.
Which devices support Disney+ in 4K?
There's more UHD content on Disney+ right now than I thought there'd be this early on, but unfortunately playing it will require a 4K Smart TV that supports UHD playback — or an 4K supported entertainment console connected to a 4K TV that supports HDCP 2.2 — so even if you have a 4K screen hooked up to your gaming PC, you won't be streaming 4K that way. There are plenty of 4K devices supported, such as the NVIDIA Shield TV 2019, as well as a whole host of excellent 4K TVs at every price point from $300 to $3000.
What can I watch on Disney Plus?
Source: Ara Wagoner / Android Central
Disney has prided itself on its Vault of extensive content for decades. While the Disney Vault strategy was starting to decay in the digital age, Disney+ will reap most of its rewards by hosting most of the Disney Vault as well as an impressive array of content from Marvel, Lucasfilm, Fox, and National Geographic. Right now, Disney+ has about 500 films and over 7,500 TV episodes, including most of films in the Marvel Infinity Saga and Star Wars Skywalker Saga.
There's tons to watch, but unfortunately Disney didn't see fit to put all of its films in ordered playlists for easy marathoning. This would be especially handy for the Marvel Cinematic Universe, but since Disney doesn't have a handy playlist, we went ahead and made one so you can focus on prepping snacks for your Marvel movie marathon!
Speaking of tons to watch, I waited a long time to get all of my favorite shows and movies in one easy-to-use place, and as such that meant that I had a long list of things I needed to watch, rewatch, and rewatch again because it's been so long since I've seen them. These are the first 16 films and shows I watched on Disney+.
What more can I watch with the Disney Plus Bundle?
Disney+ is just one of the major digital platforms Disney is serving up in this new streaming era. It's the largest, for sure. But it's also just one part of the puzzle.
- Want to keep your ad-free Hulu with the Disney+ bundle? Here's how
- How to upgrade from Disney+ to the Disney+ bundle with ESPN+ and Hulu
Have a look at ESPN+
If nothing else — and if you're a sports fan of any kind — you also should consider a subscription with ESPN+. It runs on the same underlying platform as Disney+, so you'll be pretty familiar with how things work.
And as for the content, well. If you thought there was a lot of sports of TV, wait until you get a look at ESPN+. Yes, it's got live sports. All kinds of live sports. It's got college football games that you can't find on TV. It's got a huge amount of college basketball. It's got a smattering of NHL. It's got boxing and UFC — in fact, you have to have ESPN+ if you want to watch pay-per-view UFC events — and rugby and cricket and ... you name it.
And then there's the matter of original content. Think Peyton Manning was resting in his retirement? Not quite. Peyton's Places is keeping him plenty busy. Plus football coach Les Miles has a show, you can find the irreplaceable duo of Boomer and TJ — and so much more, right there on ESPN+.
And, yes, you can watch ESPN+ on your TV, too.
More sports!
 There simply is no limit to the off-TV games you'll be able to watch, plus tons of original content.
And don't forget Hulu
The third arm of the trifecta is Hulu, which also is controlled by Disney. It's where you'll find all the on-demand content you've come to know from that service, as well as original shows like The Handmaid's Tale.
And perhaps more important for Disney's purposes is Hulu with Live TV which, as the name implies, gets you live (and local) television alongside all that other content.
Stream this
Hulu
The full Hulu experience is expansive
Hulu becomes even more appealing when it gets bundled with Disney+ and ESPN+ for just $12.99 a month. Still to come is how much extra Live TV might cost under that plan.
How does the Disney Plus library compare outside the US?
There are differences in available content between countries — for instance, French law forbids theatrically released films from being put on a streaming service in that country for three years, so don't expect to see Avengers: Endgame on Disney+ in France until 2021.
So far, however, the differences between the available content in the United States, Canada, and the Netherlands has been small, mainly that a few more of the recent Marvel and Disney films are currently unavailable.
How long will it take for new movies to be added to Disney Plus?
The newest films in Disney's repertoire aren't available on Disney+ right now, but for most of them we won't be waiting too long. Movies will launch on Disney+ after the full theatrical and home video release, which will vary between individual films but should be 5-8 months after the theatrical release.
Parental controls, profiles, and account limits
Source: Ara Wagoner / Android Central
Since Disney+ allows up to 7 user profiles on a single account — and up to four users streams at a time — it's only natural that Disney+ accounts are meant to be shared amongst family. However, when the kids are misbehaving or when a friend isn't chipping in the way they promised they would when you let them have your login, it's time to change the password and lock them out!
It's very easy to get sucked in while watching your favorite shows on Disney+ — I put on an episode of Kim Possible to watch during lunch and then POW, it's dinnertime! — but if you want to give yourself a leg up against being sucked in by the siren song of the binge watch, turn off Autoplay. Having to hit play every 20 or 40 minutes can help you break the cycle and get back to work, and since Autoplay is profile-based, you can turn it off for your kids account while leaving it on for yours.
As a streaming service that is geared so much towards towards families and kids, parental controls on Disney+ are pretty simplistic at the moment: you can set up a child's profile and set it to only allow content with a certain rating. Rather than giving age-based restrictions, Disney's content filter works based on the MPAA and US television content ratings systems, meaning that you'll have to decide if you want your child to see only G/TV-G content or allow in TV-Y7 and TV-Y7/FV.
Tips, tricks, and troubleshooting: How to get the most out of Disney Plus
Source: Ara Wagoner / Android Central
Like any new, popular online service, Disney+ is not all smooth sailing, as magical as it may seem at first glance. Disney+ saw more users sign up on Day One as it expected in all of Year One, so overloaded servers have been the most prevalent problem so far, as evidenced by how widespread Error 83 has been.
Of course, not all connection issues are related to server strain, you might need to check and make sure your internet is fast enough. On some iPhones, you can get around Error 83 by switching from Wi-Fi to LTE, but you'll want to remember that streaming Disney+ that way can eat a capped data plan alive. When servers are slow or your network is down completely, you can still watch the Disney+ videos you downloaded to your phone, tablet, or Chromebook, at least.
What does Disney Plus cost?
| Country | Monthly rate | Annual rate |
|---|---|---|
| United States | $6.99 | $69.99 |
| Canada | $8.99 CAD | $89.99 CAD |
| Netherlands | €6.99 | €69.99 |
| Australia | $8.99 AUD | $89.99 AUD |
| New Zealand | $9.99 NZ | $99.99 NZ |
The pricing of Disney+ varies a bit from country to country, but in all countries you can save yourself a few bucks by opting for the annual billing rate rather than the monthly billing. One account can have up to four streams going at one time and up to seven profiles on the account, so you probably won't need to shell out for multiple accounts in one family.
What's the best Disney Plus deal I can get?
Disney also has a bundle option that gives users Disney+, ESPN+, and ad-supported Hulu for $12.99 a month. It gets a little complicated, but the short version is if you have separate accounts on each of the three services, you can link them together in a sort of virtual bundle via a single email address. You pay Disney+ once a month, and Disney+ applies credits to ESPN+ and Hulu paying . You should still be able to keep the various Hulu add-ons like Hulu with Live TV and Limited Commercials via this method.
Better together
Disney+ Bundle
This is the best deal in streaming today.
Since the Disney/Fox content that's deemed too adult for Disney+ will go to Hulu, this bundle ensures that you'll be able to watch all the content under Disney's big umbrella. You'll also be able to watch all the sports on ESPN+ like UFC fighting.
Disney offered a 33% discount on a three-year subscription to D23 members back during and after the D23 Expo in August that has since closed. You had to pony up for the entire three-year subscription upfront, but you essentially paid two years to get one free, so for die-hard Disney fans, this was an excellent deal.
Disney+ on Us: how to get a free year from Verizon
Source: Ara Wagoner / Android Central
If you have a Verizon unlimited plan, you can get a year of free Disney+ thanks to a promotion it's calling "Disney+ on Us. You can sign up for your free year through Verizon's website, and if you'd already taken advantage of the D23 three-year subscriptions, congratulations, you can stack promotions and get four years for the price of two. Oh, how I envy you!
Are we expecting any Disney Plus deals on Black Friday?
Considering that Disney+ doesn't currently allow any promo codes, I wouldn't hold my breath on seeing any specific Black Friday discounts, especially since the service just launched.
Can I give Disney Plus as a gift this Christmas?
At the moment, Disney+ memberships have to be purchased directly, but Disney is supposed to launch Disney+ gift cards that can be given as gifts soon. No concrete timeline was given, but I'm optimistic we'll see Disney+ gift cards available by the first week in December so that Disney can capitalize on the holiday shopping season.
How does Disney Plus stack up to the competition?
Disney+ is entering an already crowded streaming market, pitting a brand new product against seasoned services like Netflix and Amazon. The content available for Disney+ is quite impressive, and the pricing is even more so, with the Disney+ bundle still costing less than a Netflix Premium subscription, which has made it quite easy for many to swap over to Disney's offerings.

- Setup - The basics of getting started with attachmentgenie/ssh
- Usage - Configuration options and additional functionality
- Development - Guide for contributing to the module
Overview
The module makes it possible to install a ssh server and/or client and to add authorized ssh keys to existing users.
Setup
What attachmentgenie/ssh affects
- ssh server
- ssh client
- add authorized ssh keys to existing users.
Beginning with attachmentgenie/ssh
The ssh::client
class installs the ssh client:
class { 'ssh::client': }
The ssh::server
class installs and configures the sshd:
class { 'ssh::server':
password_authentication => 'yes',
}
Usage
You can specify the port the sshd should listen to by including the class with this special syntax:
class { 'ssh::server':
port => 20009,
}
You can also restrict access for only certain users:
class { 'ssh::server':
allowed_users => ['attachmentgenie', 'manager'],
}
And you can permit root logins (not recommended):
class { 'ssh::server':
permit_root_login => 'yes',
}
To permit root logins could be a serious security issue. In most cases you should
use something like sudo
instead.
You can use ssh::user
to add an authorized ssh key to an existing user
for effortless authentication with ssh:
ssh::user { 'attachmentgenie':
key => 'a8a7dgf7ad8j13g',
comment => 'attachmentgenie.com',
}
Development

<hazardstatement>
The <hazardstatement>
element contains hazard warning information. It
is based on the regulations of ANSI Z535 and ISO 3864. It enables the author to select the
type of hazard, add information about the specific hazard and how to avoid it, and add one
or more safety symbols.

--- layout: post title: Phonewords post_id: 236 categories: - reviews date: 2005-12-09 12:09:00.000000000 -07:00 author: Jamis permalink: 2005/12/9/phonewords.html ---
I was recently pointed at Phonewords, a Mac OS X Cocoa application for discovering words hidden in your phone number(s).
It also comes with an address book plugin that allows you to generate and select phonewords from within your address book. (There’s even a demo movie that shows off this feature).
The sad news is that my phone number doesn’t work out to anything meaningful. My cell-phone number at least gave me something memorable. But whether you get anything meaningful or not, it’s still a fun app to play with.

logical-pathname-translations
host ⇒ translations
(setf ( logical-pathname-translations
host) new-translations)
host–a logical host designator.
translations, new-translations—a list.
Returns the host’s list of translations. Each translation is a list of at least two elements: from-wildcard and to-wildcard. Any additional elements are implementation-defined. From-wildcard is a logical pathname whose host is host. To-wildcard is a pathname.
[Reviewer Note by Laddaga: Can this be a logical pathname?]
(setf (logical-pathname-translations host) translations) sets a logical pathname host’s list of translations. If host is a string that has not been previously used as a logical pathname host, a new logical pathname host is defined; otherwise an existing host’s translations are replaced. logical pathname host names are compared with string-equal.
When setting the translations list, each from-wildcard can be a logical pathname whose host is host or a logical pathname namestring parseable by (parse-namestring string host), where host represents the appropriate object as defined by parse-namestring. Each to-wildcard can be anything coercible to a pathname by (pathname to-wildcard). If to-wildcard coerces to a logical pathname, translate-logical-pathname will perform repeated translation steps when it uses it.
host is either the host component of a logical pathname or a string that has been defined as a logical pathname host name by setf of logical-pathname-translations.
[Reviewer Note by Laddaga: Shouldn’t there be some *.*’s in the list of translations for PROG below?]
;;;A very simple example of setting up a logical pathname host. No ;;;translations are necessary to get around file system restrictions, so ;;;all that is necessary is to specify the root of the physical directory ;;;tree that contains the logical file system. ;;;The namestring syntax on the right-hand side is implementation-dependent. (setf (logical-pathname-translations "foo") '(("**;*.*.*" "MY-LISPM:>library>foo>**>"))) ;;;Sample use of that logical pathname. The return value ;;;is implementation-dependent.

This Unix doesn't support ;;;:WILD-INFERIORS in the directory, so each directory level must ;;;be translated individually. No file name or type translations ;;;are required except for .MAIL to .MBX. ;;;The namestring syntax on the right-hand side is implementation-dependent. (setf (logical-pathname-translations "prog") '(("RELEASED;*.*.*" "MY-UNIX:/sys/bin/my-prog/") ("RELEASED;*;*.*.*" "MY-UNIX:/sys/bin/my-prog/*/") ("EXPERIMENTAL;*.*.*" "MY-UNIX:/usr/Joe/development/prog/") ("EXPERIMENTAL;DOCUMENTATION;*.*.*" "MY-VAX:SYS$DISK:[JOE.DOC]") ("EXPERIMENTAL;*;*.*.*" "MY-UNIX:/usr/Joe/development/prog/*/") ("MAIL;**;*.MAIL" "MY-VAX:SYS$DISK:[JOE.MAIL.PROG...]*.MBX"))) ;;;Sample use of that logical pathname. The return value ;;;is implementation-dependent. (translate-logical-pathname "prog:mail;save;ideas.mail.3") ⇒ #P"MY-VAX:SYS$DISK:[JOE.MAIL.PROG.SAVE]IDEAS.MBX.3" ;;;Example translations for a program that uses three files main.lisp, ;;;auxiliary.lisp, and documentation.lisp. These translations might be ;;;supplied by a software supplier as examples. ;;;For Unix with long file names (setf (logical-pathname-translations "prog") '(("CODE;*.*.*" "/lib/prog/"))) ;;;Sample use of that logical pathname.

The return value ;;;is implementation-dependent. (translate-logical-pathname "prog:code;documentation.lisp") ⇒ #P"/lib/prog/docum.lisp" ;;;For Unix with 14-character file names, using .l as the type ;;;The second translation shortens the compiled file type to .b (setf (logical-pathname-translations "prog") `(("**;*.LISP.*" ,(logical-pathname "PROG:**;*.L.*")) (,(compile-file-pathname (logical-pathname "PROG:**;*.LISP.*")) ,(logical-pathname "PROG:**;*.B.*")) ("CODE;DOCUMENTATION.*.*" "/lib/prog/documentatio.*") ("CODE;*.*.*" "/lib/prog/"))) ;;;Sample use of that logical pathname. The return value ;;;is implementation-dependent. (translate-logical-pathname "prog:code;documentation.lisp") ⇒ #P"/lib/prog/documentatio.l" ;;;For a Cray with 6 character names and no directories, types, or versions. (setf (logical-pathname-translations "prog") (let ((l '(("MAIN" "PGMN") ("AUXILIARY" "PGAUX") ("DOCUMENTATION" "PGDOC"))) (logpath (logical-pathname "prog:code;")) (phypath (pathname "XXX"))) (append ;; Translations for source files (mapcar #'(lambda (x) (let ((log (first x)) (phy (second x))) (list (make-pathname :name log :type "LISP" :version :wild :defaults logpath) (make-pathname :name phy :defaults phypath)))) l) ;; Translations for compiled files (mapcar #'(lambda (x) (let* ((log (first x)) (phy (second x)) (com (compile-file-pathname (make-pathname :name log :type "LISP" :version :wild :defaults logpath)))) (setq phy (concatenate 'string phy "B")) (list com (make-pathname :name phy :defaults phypath)))) l)))) ;;;Sample use of that logical pathname. The return value ;;;is implementation-dependent. (translate-logical-pathname "prog:code;documentation.lisp") ⇒ #P"PGDOC"
If host is incorrectly supplied, an error of type type-error is signaled.
Implementations can define additional functions that operate on logical pathname hosts, for example to specify additional translation rules or options.

This page contains the information on how to access your hosted web application
through a
Instead of going through this long URL process, we provide a way to access your hosted web application with a short URL like https://appid.localhost:port/ in standalone products. If your App Server is fronted with load balancher, then https://appid.localhost can be used.
Eventually, your shorten URL will be mapped as below.
http://localhost:port/webapps/t/tenant_domain/webappname ==> https://appid.localhost:port
Figure 1: URLmappings in web application information page.
When you click on in web application dashboard, you can get the URL mappings page. You can add the mappings here.
Figure 2: adding a URLmapping to webapp
URL mappings page has the options to control over your URL mappings such as edit and delete.
Figure 3: control the URLmapping to webapp
Once you created URL mapping of a web application, let's take the mapping name as "exampleapp", then your domain will be "exampleapp.localhost" where the suffix "localhost" comes from CARBON_HOME/repository/conf/etc/url-mapping-config.xml. You can configure your own suffix and URL mappings limit per web application in the configuration file above. By default suffix is "localhost" and URL mappings limit is one.
The following image depicts how your web application could accessed through your own domain in a browser.
Figure 4: accessing web application with shorten url.
You have to create a cname to access your own domain. In case cname is not available with you at the moment, you can use /etc/hosts to put your domain entries by pointing to your local ip which can only be applicable for testing purposes.
If you create a URL mapping for a service through service dashboard as shown below, you can follow the same steps like web application to access your wsdls, tryit and rest calls with the short urls.
"http://servicetest.localhost:port?wsdl" - to access wsdl of your service
"http://servicetest.localhost:port?tryit" - to access tryit of your service
"http://servicetest.localhost:port/getQuote" - to access rest call of your service
Figure 5: URL mappings in services-dashboard
Admin can view all the URL mappings through monitor --> . Admin can search by tenants to get URL mappings of particular tenant.

About this game 🤳
Emoji Scavenger Hunt is a browser-based game built with machine learning that uses your phone’s camera and a neural network to try and guess what it’s seeing. This is just one example of how machine learning can be used in fun ways.
Powered by Tensorflow.js, the game is built to run efficiently on your phone’s web browser without needing to access backend servers. No images from your camera are collected or stored.
Watch the video above to see how the project was created, browse the open-source code on GitHub to learn more about how it works, or explore more A.I. Experiments like this.
This experiment was made by friends from the Brand Studio and PAIR teams at Google.
Faq 🙋
- It doesn’t work on my phone.
Being an experiment and all, we're using the latest web technologies. It works best on phones & browsers like the latest version of Chrome on Google Pixel or other smartphones running the latest Android OS, or Safari on newer iPhones running the latest iOS.
- Why doesn’t it recognize some items?
It’s an experiment, and well, not perfect. We think seeing what works and what doesn’t is one way to help explore and understand how machine learning works.
- Are my images being stored on Google servers?
No. All the interactions are happening locally on your device. If you’re curious, check out our open-source code on GitHub
