BATMAN A film review by Mark R. Leeper Copyright 1989 Mark R. Leeper
Capsule review: A triumph of visual imagery over story for the music video generation. Ironically, Keaton is better as Batman than Nicholson is as the Joker. The art design is superior but just about everything else is pedestrian. Better than the television series or the serials, not as good as the comic. Rating: 0.
"[The] mind craves [images], and, of late more than ever, the keenest experimenters find twenty images better than one, especially if contradictory; since the human mind has already learned to deal in contradictions." Henry Adams, 1907
Excuse the pretentiousness of starting a review with an 82-year-old quote, but Adams might very well be talking about BATMAN, whose images, often contradictory or of clashing styles, far overpower the flyweight story that binds them together. BATMAN is a triumph of visual imagery over story. While Jack Nicholson is the top-billed star, his character is paper-thin and just as flat. We are down here to the level of villains whose biggest crimes can be explained only by nastiness. Nicholson apparently was chosen not because he had a single responsive chord for the man behind the famous face, but because both are known for their smirking. Nicholson does not even look the part. His face is not thin and angular enough and his non- angular body is better suited to playing the Penguin. Of course, it is a pity that the original model for the Joker is well past the point where he could have played the part. Conrad Veidt, best known for playing Col. Strasser in CASABLANCA and Cesar in CABINET OF DR. CALIGARI, played the title role in THE MAN WHO LAUGHS, a poor wretch whose face is twisted into a perpetual rictus grin. His nightmarish look was reportedly the real inspiration for the Joker so he looked the role. Nicholson can be a decent actor but he lacks range and in spite of all the fuss and expectation, Michael Keaton is much better cast as Batman than Nicholson is as the Joker. Keaton, first of all, looks the part of Batman. That is not all that surprising if you realize what you are seeing is two eyes, a perpetual frown, and a chin. Everything else is plastic shell. Any actor with a chin and reasonable musculature could have looked good in the Batman suit. Keaton's role was a little more demanding when he played the man behind the mask--he is not a character out of Dostoevsky, understand, but his role did require a little acting and while he was neither superior nor memorable, he was at least equal to the role. Surprisingly, Michael Gough played against type as a sympathetic Alfred the butler (sort of a Batman's batman!). At one point he does severely overstep what the original Alfred would have done, but that is a script fault, not Gough's failing.
The story, what there is of it, gives us an origin for the Joker, a touch of one for Batman, and one fiendish though not very coherent scheme by the Joker which is, f course, foiled by Batman. I will not say much about the Joker's scheme, but it involves chemical contamination. The Joker makes the part about chemical contamination quite public, but apparently Batman is the only person to do a chemical analysis of the contaminated products. (To judge how likely that is, the Berkeley ellness Letter reports, "The smoke from a single cigarette contains about 100 times more cyanide than did the two grapes from Chile that were impounded by government officials in March." Any idea how many chemical labs got involved in analysis after that tiny level of contamination was found? How likely do you find it that only Batman would do a complete chemical analysis of the Joker's product?) The plot also concerns what must be the world's tallest cathedral. At a minimum it looks to be at least fifty stories tall. That does not make for a believable story, but it is there for visual style more than credibility.
In the quote above, Adams talks about contradictory images, and that is precisely what BATMAN offers. There are wide mood swings from somber, dark, and brooding, to just exactly the sort of tongue-in-cheek campiness that the producers have long promised would *not* be in this film. Scenes of the Joker dancing Mardi Gras fashion to songs by Prince in front of cheering crowds are not classic Batman style by any means. And when Batman laments, "This is not exactly a normal world," this is not exactly a Batman sentiment. Also, one wonders how many worlds Batman has seen. Again and again the story stops--literally stops--in a time-out for a visual image. One of the most ridiculous of these has the Batplane break off a confrontation with the Joker so it can fly above the clouds and be seen outlined against the moon, looking like an aerial bat-symbol. If the script gives no explanation, the cheer of the audience does. Logic is less important than the visual image.
BATMAN is an art designer's film all the way. Gotham City is a highly stylized New York City with the art deco of the 1930s and the futuristic feel of Fritz Lang's (not Superman's) Metropolis. It is a collection of dark somber streets seen only at night or under overcast skies. This is a film without sunshine. To tie Gotham to the present, the mayor of the city was cast not for any acting ability, but because he looks like Ed Koch. In spite of the beautiful visual design for the city, the eye still rebels because of the matte paintings and building models that are just not convincing as being anything but mattes and models. That is not a serious fault in a film with a strong story, but when a film's strongest suit is its art design, it becomes very important to execute those designs flawlessly.
Finally, a word about the music. Danny Elfman has written a decent score, but choosing Prince to write the songs, apparently for the nihilism of his previous work, was as big a blunder as choosing Nicholson for his smirk. Director Tim Burton claims to be a fan of Batman comic books, but it seems to me they were better than his film. I have to give the film a neutral 0 on the -4 to +4 scale. I guess I did not expect better, but I had hoped for it nonetheless.

Python offers an interactive mode that lets you evaluate an expression at a time. This is an excellent way to learn the language. We will step rapidly through the main features of the language in interactive mode. We won't provide detailed explanations, since most features are remarkably clear and obvious anyway.
Either go to an MS-DOS prompt, or (if you've already installed it) start PythonWin. You should see something like this:
Pythonwin 1.5.2b2 (#0, Feb 16 1999, 17:09:09) [MSC 32 bit (Intel)] on win32 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam Portions Copyright 1994-1998 Mark Hammond<EMAIL_ADDRESS>>>>
You can type in simple expressions, which are evaluated for you:
>>> 2+2 4
You can assign to variables with =. There is no separate declaration required before you assign a variable:
>>> x=3 >>> x 3 >>> y=x*2 >>> y 6 >>>
Python supports all standard arithmetic operators. Note that the division operator ( / ) yields different results on integer and floating-point types:
>>> 22 / 7 3 >>> 22.0 / 7.0 3.14285714286 >>>
Scientists and mathematicians will be pleased to hear that complex numbers are fully supported using the letter j :
>>> (3 + 1j) * (3 - 1j) (10+0j) >>>
Strings can be wrapped in either double or single quotes. They can be concatenated with the + operator and repeated with the * operator. You can also access individual characters by their position:
>>> greeting = 'hello' >>> epithet = 'stranger' >>> greeting + ", " + epithet 'hello, stranger' >>> "spam" * 10 'spamspamspamspamspamspamspamspamspamspam' >>>
Much of Python's power comes from its support for lists and its compact syntax for manipulating them. Lists are wrapped in square brackets and can contain any Python objects. You can also insert and delete items in a list and even use negative positions to access the end of the list without knowing its length:
>>> mylunch = ['spam','eggs', 'guinness','raspberries','wafer-thin mint'] >>> mylunch[0] 'spam' >>> mylunch[1:3], mylunch[-1] (['eggs', 'guinness'], 'wafer-thin mint') >>>
When you enter two results separated by a comma on the same line, you get two expressions, but enclosed in parentheses. Parentheses indicate a tuple , which is similar to a list but can't be modified once created:
>>> mylunch[2] = 'tea' >>> mylunch ['spam', 'eggs', 'tea', 'raspberries', 'wafer-thin mint'] >>> meal_deal = ('burger','fries','coke') # a tuple >>> meal_deal[1] = 'onion rings' Traceback (innermost last): File "<interactive input>", line 1, in ? TypeError: object doesn't support item assignment >>>
The last example also shows our first error message. When errors occur, you see a traceback stating which functions were active and the line of the source file that caused the error, as well as the error type and message on the last line. In this case, you type commands interactively rather than running a source file, so you don't see a helpful filename or line number.
The for loop actually operates over lists, not numbers:
>>> for item in mylunch: ... print item ... spam eggs tea raspberries wafer-thin mint >>>
There are several things to note at this point. First, after typing the colon and pressing the Return key, Python indents the next line, and you don't have to type anything to end the for loop. Python actually uses indentation for syntax, saving typing and making the language highly readable: the layout of code on the page indicates its structure. A second point is that the >>> prompt changes to ... for subsequent lines. This indicates that Python knows you are entering a multiline statement at the command prompt.
Another common structure is the while loop:
>>> x = 2 >>> while x < 50: ... x = x * 2 ... print x ... 4 8 16 32 64 >>>
The if structure is also present; the else clause is optional:
>>> if 'chocolate' in mylunch: ... print "that's not allowed" ... else: ... print "enjoy your meal" ... enjoy your meal >>>
You can also have a number of intermediate elif clauses, short for else-if. These allow something like the switch or case statements in other languages:
>>> salary = 20000 >>> if salary < 4000: ... tax_rate = 0 ... elif salary < 29000: ... tax_rate = 0.25 ... elif salary < 100000: ... tax_rate = 0.4 ... else: ... emigrate() # that's a function call ... >>>
Functions are defined by the def statement and use return to exit immediately from the function and return a value. You can return more than one value by using a tuple or return no value at all:
>>> def double(x): ... return x * 2 ... >>> double(2) 4 >>> def first_and_last(aList): ... return (aList[0], aList[-1]) ... >>> first_and_last(range(5)) (0, 4) >>> def sayHello(): ... print 'hello' ... >>> sayHello() hello >>>
Functions may have default arguments that allow them to be called in certain ways or allow you to initialize variables:
>>> def makeCoffee(size, milk=None, sugar=None): ... order = 'one ' + size + ' coffee' ... if milk and sugar: ... order = order + ' with milk and sugar' ... elif milk: ... order = order + ' with milk' ... elif sugar: ... order = order + ' with sugar' ... else: ... pass # pass means 'do nothing' ... return order ... >>> makeCoffee('large') 'one large coffee' >>> makeCoffee('large', 1) 'one large coffee with milk' >>> makeCoffee('large', milk=0, sugar=1) 'one large coffee with sugar' >>>
Note that you can name the arguments and that both 0 and the special variable None are treated as false.
Python also offers a dictionary type. This is based on a hash table, and the lookup time is almost constant, irrespective of size. Dictionaries are enclosed in braces ({ }), and the keys and values are displayed separated by a colon. You can access and set their elements with a notation similar to list indexes:
>>> fur_colors = {} >>> fur_colors['Tinky-Winky'] = 'purple' >>> fur_colors['Dipsy'] = 'green' >>> fur_colors['LaLa'] = 'yellow' >>> fur_colors {'Tinky-Winky': 'purple', 'Dipsy': 'green', 'LaLa': 'yellow'} >>> fur_colors['LaLa'] 'yellow' >>>
Dictionaries have no natural order. They support some useful methods of searching, e.g., by keys, values, and whether or not a certain key is present:
>>> fur_colors.keys() ['Tinky-Winky', 'Dipsy', 'LaLa'] >>> fur_colors.values() ['purple', 'green', 'yellow'] >>> fur_colors.items() # converts to a list of tuples [('Tinky-Winky', 'purple'), ('Dipsy', 'green'), ('LaLa', 'yellow')] >>> len(fur_colors) 3 >>> fur_colors.has_key('Po') 0 >>>
Lists and dictionaries together allow you to build more powerful data structures, such as sets or even database indexes, in few lines of code. The values in a dictionary can be anything, while the keys can be strings, numbers, or tuples of other values. In Chapter 6, we show how to construct some extremely useful utilities from dictionaries.
Python code is organized into modules . A module must be loaded into memory using the import statement. Some modules are built into Python and always available; others are stored in external files. Modules can also be written either in C (in which case they are compiled as a special kind of DLL) or in Python (in which case they are saved in text files ending in .py ). As far as the user is concerned, they are all used the same way:
>>> import math >>> math.sin(math.pi/2) 1.0 >>>
We used both a function and a constant from the math module. Note that the module's name must be prefixed. This prevents namespace collisions: imagine how many different programs might wish to define a function called read( ) or save( ). It's also possible to import a function explicitly into the present namespace:
>>> from string import split, join >>> split('We are the knights who say Ni') ['We', 'are', 'the', 'knights', 'who', 'say', 'Ni'] >>>
This procedure can be used for brevity but increases the risk of a collision, and, more important, of losing track of what your code means a few months later. It should be used sparingly.
Python makes object-oriented programming easy. The class statement begins the definition of a class. Classes can use a special constructor called __init__( ) to initialize their data. Because Python doesn't declare variables, this constructor is a common place to initialize any variables the class may require:
>>> class Car: ... def __init__(self): ... self.milespergallon = 25.0 ... self.travelled = 0 ... self.color = 'blue' ... self.gas = 20 ... def drive(self, miles): ... self.travelled = self.travelled + miles ... self.gas = self.gas - (miles / self.milespergallon) ... >>> c = Car() >>> c.drive(100) >>> c.travelled 100 >>> c.gas 16.0 >>>
Note that you have to use the keyword self each time you access an attribute.
As with other languages, classes may inherit from a base class and be initialized with arguments supplied by the constructor. We won't give any further examples at this point; you can see many classes throughout this book, and the syntax is self-evident if you are used to object-oriented programming.
When errors occur, Python throws an exception and prints an informative traceback to standard output. If the error occurred in a source file and not a console session, you get the filename and line number. Here's a simple error, nested three functions deep, and its traceback:
>>> def func1(arg): ... func2(arg) ... >>> def func2(arg): ... func3(arg) ... >>> def func3(arg): ... # this should cause an error ... return arg / 0 ... >>> func1(17) Traceback (innermost last): File "<interactive input>", line 0, in ? File "<interactive input>", line 2, in func1 File "<interactive input>", line 2, in func2 File "<interactive input>", line 3, in func3 ZeroDivisionError: integer division or modulo >>>
The traceback tells us where the error happened and the enclosing functions that called the functions that caused the error.
Exceptions can be handled using the try ...except and try ...finally structure. If you aren't used to exception handling, these offer two benefits over Visual Basic-style error-handling. First, you can write a decent-sized chunk of code and put the error handlers at the end; the intent of the programmer is clearer than with a lot of on error goto and on error resume next statements. Second, exception handlers don't work on just the present chunk of code, but also on any subroutines within it, however deeply nested.
The except clause can optionally specify particular error types to look for or handle all errors:
>>> try: ... y_scale_factor = plotHeight / (dataMax - dataMin) ... except ZeroDivisionError: ... y_scale_factor = 0 ... >>>
The try ...finally clause always executes the finally section whether an error occurs or not. This ensures that resources such as files are freed up:
>>> f = open('somefile.dat', 'wb') >>> try: ... #fetch some data ... #store it in the file ... finally: ... f.close() # make sure the file is closed, ... # even if errors occurred ... >>>

Money Play. How should Red play 54?
pips Red=182 White=158
(CorrectAnswer= 0/0, ErrorScore= 0)
Position submitted by: Peder Berkell
Another third roll position after Red 41: 13/9, 6/5 White 54: 24/20, 13/8. How should Red play his 54?
He can play (a) bar/20, 24/20 or (b) bar/20, 13/9 or (c) bar/20, 9/5*
Hitting is wrong because Red already trails in the race. Making the outside point is wrong basically because it makes the wrong point. Anchoring is correct because it creates a long-term asset and duplicates White’s fours
Both (b) and (c) are blunders.

Moving from mysql to postgres
| New Articles |
By now we have made sufficient progress in our attempt of adding pgsql support for Rad User Manager that we were able to login to the system during the last step. We have a few more changes to make, one of the most important tasks is to complete the user signup section.
Some of our tables have auto_increment fields these are known as sequence fields in postgresql. As you know when a row is inserted into such a table the auto increment field is assigned a sequential number by the database. Sometimes we find that we need to retrieve this number as happens during the sign up process. The mysql_insert_id function of PHP is what is being currently used for this purpose but unfortunately the postgres functions of PHP does not include an equivalent.
Fortunately postgres includes a currval() function which can be used to find the last value picked off the sequence, but before we make use of it we need to side track a bit because the automatically assigned value is meaningless for us if an error was encountered when executing the query. Therefor we need to polish up the error handling before we make use of currval.
function db_error_log() { global $db_type; if($db_type == 'mysql' && mysql_errno() != 0) { $errMessage = mysql_error(); error_log($errMessage); return $errMessage; } else { $errMessage = pg_last_error(); error_log($errMessage); return $errMessage; } }
These few lines of code will log the last error reported by the DB. The is usually written to your webserver log file but check your php.ini settings and your webserver's documentation to be sure. The same message is returned to the calling method.
Let's do a search and replace for all occurances of mysql_error with our newly build db_error_log. We need to watch for any occurances of mysql_errno as well. Since it's exact equivalent does not exist on the other system we need to make a slight modification to our code.
$err = db_error_log(); if($err !='') { .... }
Now that error handling is out of the way, let's create a function to retrieve the insert id. Notice that it accepts a single parameter which is the name of the sequence in pgsql but needs not be defined in mysql. So we give it a default value.
function db_insert_id($sequence='') { global $db_type; if($db_type == 'mysql') { return mysql_insert_id(); } else { $result = pg_query("SELECT currval('$sequence')"); if($result) { $row = pg_fetch_row($result); return $row[0]; } } }
Since we already have quite three snippets of code on this page let's not overload it with another sample on how we should change calls to mysql_insert_id but don't forget to make the changes that you will find in the download.

The shower problem
08 Feb 2020Attention mathematicians and computer scientists: I’ve got a problem for you, and I don’t know the solution.
Here’s the setup: You’re at your friend’s place and you need to take a shower. The shower knob is unlabeled. One direction is hot and the other direction is cold, and you don’t know which is which.
You turn it to the left. It’s cold. You wait.
At what point do you switch over to the right?
The baseline shower problem
Let’s make this more explicit.
- Your goal is to find a policy that minimizes the expected amount of time it takes to get hot water flowing out of the shower head. To simplify things, assume that the water coming out of the head is either hot or cold, and that the lukewarm transition time is effectively zero.
- You know that the shower has a Time-To-Hot constant called \(\tau\). This value is defined as the time it takes for hot water to arrive, assuming you have turned the knob to the hot direction and keep it there.
- The \(\tau\) constant is a fixed property of the shower and is sampled once from a known distribution. You have certain knowledge of the distribution, but you don’t know \(\tau\).
- The shower is memoryless, such that every time you turn the knob to the hot direction, it will take \(\tau\) seconds until the hot water arrives, regardless of your prior actions. Every time you turn it to the cold direction, only cold water will come out.
I don’t know how to solve this problem. But as a starting point I realize it’s possible to keep track of the probability that the hot direction is to the left or to the right. In the animation above, the probability that the hot direction is to the right is just the unexplored white area under the right curve, divided by the total unexplored white area of both curves.
But how do you turn that into a policy for exploring the space? Does anybody know?
Submissions
If you would like to submit a proposal, please report your average duration for the sample of 20,000 \(\tau\)’s provided here.
On February 9, 2020, Cameron Davidson-Pilon took an early lead, with an average duration of 111.4 seconds.
On June 22, 2021, Allen Downey took the lead with an average time of 102 seconds, pending verification.
On July 11, 2021, Jake Westfall took the lead with an average time of 101.5 seconds.
Bonus problem: Plumbing realities and the elusive “Middle Solution”
The baseline shower problem assumes a simplified version of reality, where the shower is memoryless and there is only a single pipe. If you want a harder problem, I have written a comment below that describes some of the plumbing realities, including lag and the existence of separate hot and cold pipes. The comment explores the tantalizing possibility that we’ve all been fiddling with our showers wrong this whole time. Instead of swinging the knob between one extreme and the other, what if the optimal solution is to start by putting the knob in the middle? To read more, see the comment below.

NFL, Los Angeles Chargers shoot down report of team's alleged interest in moving to London
by Ryan GaydosOfficials with the NFL and the Los Angeles Chargers on Tuesday slammed a report claiming the team was interested in relocating to London — just a few years after picking up in San Diego and arriving in LA.
The NFL and the Chargers were responding to a report from The Athletic that officials could look to move the team because of their struggles with fans in the Los Angeles market.
CAROLINA PANTHERS PLACE CAM NEWTON ON INJURED RESERVE, LIKELY ENDING QUARTERBACK'S YEAR
“No consideration has been given to the Chargers playing anywhere other than Los Angeles at the new stadium in Hollywood Park next season and beyond,” the NFL said in a statement. “There have been no discussions of any kind between the NFL and the Chargers regarding moving to London. Both our office and the Chargers are entirely focused on the success of the team in Los Angeles.”
Chargers owner Dean Spanos was far less formal in his response to the report, telling the Los Angeles Times that the report was “a lot of crap.”
“We’re not going to London. We’re not going anywhere. We’re playing in LA. This is our home, and this where we’re planning to be for a long f------ time,” Spanos said. “Period. OK? If you want me to say it again, I’ll say it again. F------ bulls--- that story. OK? Thank you.”

The Chargers also released a response on the team’s official Twitter account. It was a clip of a scene from “The Wolf of Wall Street” in which Leonard DiCaprio’s beleaguered character, Jordan Belfort, tells his employees he's not “f------ leaving.”

Instance Attribute Details
#audio_duration ⇒ String
(rw)
Specify this setting only when your output will be consumed by a
downstream repackaging workflow that is sensitive to very small
duration differences between video and audio. For this situation,
choose Match video duration. In all other cases, keep the default
value, Default codec duration. When you choose Match video duration,
::Aws::MediaConvert
pads the output audio streams with silence or trims
them to ensure that the total duration of each audio stream is at
least as long as the total duration of the video stream. After
padding or trimming, the audio stream duration is no more than one
frame longer than the video stream. ::Aws::MediaConvert
applies audio
padding or trimming only to the end of the last segment of the
output. For unsegmented outputs, ::Aws::MediaConvert
adds padding only to
the end of the file. When you keep the default value, any minor
discrepancies between audio and video duration will depend on your
output audio codec.

#audio_group_id ⇒ String
(rw)
Specify the audio rendition group for this audio rendition. Specify up to one value for each audio output in your output group. This value appears in your HLS parent manifest in the EXT-X-MEDIA tag of TYPE=AUDIO, as the value for the GROUP-ID attribute. For example, if you specify "audio_aac_1" for Audio group ID, it appears in your manifest like this:
EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio_aac_1". Related setting:
To associate the rendition group that this audio track belongs to with a video rendition, include the same value that you provide here for that video output's setting Audio rendition sets.
# File 'gems/aws-sdk-mediaconvert/lib/aws-sdk-mediaconvert/types.rb', line 2562

#audio_rendition_sets ⇒ String
(rw)
List the audio rendition groups that you want included with this
video rendition. Use a comma-separated list. For example, say you
want to include the audio rendition groups that have the audio group
IDs "audio_aac_1" and "audio_dolby". Then you would specify
this value: "audio_aac_1,audio_dolby". Related setting: The
rendition groups that you include in your comma-separated list
should all match values that you specify in the setting Audio group
ID for audio renditions in the same output group as this video
rendition. Default behavior: If you don't specify anything here and
for Audio group ID, ::Aws::MediaConvert
puts each audio variant in its own
audio rendition group and associates it with every video variant.
Each value in your list appears in your HLS parent manifest in the
EXT-X-STREAM-INF tag as the value for the AUDIO attribute. To
continue the previous example, say that the file name for the child
manifest for your video rendition is "amazing_video_1.m3u8".
Then, in your parent manifest, each value will appear on separate
lines, like this: #EXT-X-STREAM-INF:AUDIO="audio_aac_1"...
amazing_video_1.m3u8 #EXT-X-STREAM-INF:AUDIO="audio_dolby"...
amazing_video_1.m3u8

#audio_track_type ⇒ String
(rw)
Use this setting to control the values that ::Aws::MediaConvert
puts in
your HLS parent playlist to control how the client player selects
which audio track to play. The other options for this setting
determine the values that ::Aws::MediaConvert
writes for the DEFAULT and
AUTOSELECT attributes of the EXT-X-MEDIA entry for the audio
variant. For more information about these attributes, see the Apple
documentation article
https://developer.apple.com/documentation/http\_live\_streaming/example\_playlists\_for\_http\_live\_streaming/adding\_alternate\_media\_to\_a\_playlist.
Choose Alternate audio, auto select, default to set DEFAULT=YES and
AUTOSELECT=YES. Choose this value for only one variant in your
output group. Choose Alternate audio, auto select, not default to
set DEFAULT=NO and AUTOSELECT=YES. Choose Alternate Audio, Not Auto
Select to set DEFAULT=NO and AUTOSELECT=NO. When you don't specify
a value for this setting, ::Aws::MediaConvert
defaults to Alternate audio,
auto select, default. When there is more than one variant in your
output group, you must explicitly choose a value for this setting.

#descriptive_video_service_flag ⇒ String
(rw)
Specify whether to flag this audio track as descriptive video
service (DVS) in your HLS parent manifest. When you choose Flag,
::Aws::MediaConvert
includes the parameter
CHARACTERISTICS="public.accessibility.describes-video" in the
EXT-X-MEDIA entry for this track. When you keep the default choice,
Don't flag, ::Aws::MediaConvert
leaves this parameter out. The DVS flag
can help with accessibility on Apple devices. For more information,

#i_frame_only_manifest ⇒ String
(rw)
Choose Include to have ::Aws::MediaConvert
generate an HLS child manifest
that lists only the I-frames for this rendition, in addition to your
regular manifest for this rendition. You might use this manifest as
part of a workflow that creates preview functions for your video.
::Aws::MediaConvert
adds both the I-frame only child manifest and the
regular child manifest to the parent manifest. When you don't need
the I-frame only child manifest, keep the default value Exclude.

#klv_metadata ⇒ String
(rw)
To include key-length-value metadata in this output: Set KLV
metadata insertion to Passthrough. ::Aws::MediaConvert
reads KLV metadata
present in your input and writes each instance to a separate event
message box in the output, according to MISB ST1910.1. To exclude
this KLV metadata: Set KLV metadata insertion to None or leave
blank.

#manifest_metadata_signaling ⇒ String
(rw)
To add an InbandEventStream element in your output MPD manifest for each type of event message, set Manifest metadata signaling to Enabled. For ID3 event messages, the InbandEventStream element schemeIdUri will be same value that you specify for ID3 metadata scheme ID URI. For SCTE35 event messages, the InbandEventStream element schemeIdUri will be "urn:scte:scte35:2013:bin". To leave these elements out of your output MPD manifest, set Manifest metadata signaling to Disabled. To enable Manifest metadata signaling, you must also set SCTE-35 source to Passthrough, ESAM SCTE-35 to insert, or ID3 metadata to Passthrough.

The previous post on OAuth discussed the authorization procedure in order to access protected resources form a resource server. Here, in this post, we'll actually implement code to access Facebook data of a particular user.
[caption id="attachment_460" align="aligncenter" width="844"] Get user details[/caption]
Facebook stores information in the form of Nodes, therefore every request to Facebook's Graph API would return a GraphNode object. This node would contain information about the particular request.
To request for user data, we simply do a GET request to the API with the relevant fields in the URL. Note that each and every time a resource is requested, the Access token is also passed along. Proper exception handling should also be implemented with each request too.
$response = $fb->get('/me?fields=id,name,posts.limit(2)', $_SESSION['fb_access_token']);
The GraphNode details are extracted systematically and is then passed to the html renderer in Laravel as arrays or strings.
The GraphNode contains information for accessing other resources as well.
eg. User post contents: images, story, caption etc.
[caption id="attachment_461" align="aligncenter" width="654"] Get User Profile image and Post Details[/caption]
To post a status message on the authenticated user's wall, a POST request to the /me/feed endpoint with the relevant fields would do.
[caption id="attachment_462" align="aligncenter" width="769"] Post Status message on wall[/caption]
For a user to logout, a logout URL is generated with the RedirectLoginHelper class and passed onto the html page.
[caption id="attachment_463" align="alignnone" width="1031"] Generating a logout URL[/caption]
The data retrieved from the Controller Class is sent to the front end views to render to the user. To display multiple posts, we loop through the posts array using a foreach loop.
[caption id="attachment_464" align="aligncenter" width="769"] Main View[/caption]
The end result is as follow, and it looks good too.
[caption id="attachment_465" align="aligncenter" width="861"] Main View Rendered[/caption]
A Status update to the feed, looks like this.

subseq creates a sequence that is a copy of the subsequence of sequence bounded by start and end.
Start specifies an offset into the original sequence and marks the beginning position of the subsequence. end marks the position following the last element of the subsequence.
subseq always allocates a new sequence for a result; it never shares storage with an old sequence. The result subsequence is always of the same type as sequence.
If sequence is a vector, the result is a fresh simple array of rank one that has the same actual array element type as sequence. If sequence is a list, the result is a fresh list.
setf may be used with subseq to destructively replace elements of a subsequence with elements taken from a sequence of new values. If the subsequence and the new sequence are not of equal length, the shorter length determines the number of elements that are replaced. The remaining elements at the end of the longer sequence are not modified in the operation.

Let \(\mathcal{P}\) be the set of polynomials of degree 3 or less. Explain why \(\mathcal{P}\) is a vector space, or explain why it is not.
Exploration2.1.2.
Explain why the following are subspaces of \(\mathbb{R}^3\text{.}\)
Any line through \((0,0,0)\text{.}\)
The set of all \((x,y,z)\) satisfying \(3x-4y+z=0\text{.}\)
Exploration2.1.3.
Consider the vector space \(\mathbb{R}^2\text{.}\) Explain why the following are not subspaces:
The unit circle.
The line \(x+y = 4\text{.}\)
The union of lines \(2x+3y = 0\) and \(x-y=0\text{.}\)
The first quadrant where \(x\geq 0\) and \(y\geq 0\text{.}\)
Exploration2.1.4.
Let \(W\) be the set of continuous functions \(f\) in \(\mathcal{C}(\mathbb{R})\) which satisfy \(f''(x) = 0\text{.}\) Decide if \(W\) is a subspace of \(\mathcal{C}(\mathbb{R})\text{,}\) and explain your thinking.
Subsection2.1.2Column Spaces and Sage
Sage can work with vector spaces! Let's set up our workspace.
This is like the MatrixSpace construction we have seen before. V is now the collection of all vectors of size \(3\) with rational numbers as entries.
Exploration2.1.5.
Let's see how to get column spaces from Sage. First, let's define a \(2\times 3\) matrix \(A\text{.}\) Now, we get the column space.
Note that SageMath gives information in terms of a basis. We will talk about this concept soon.

The differences between Javascript constructor functions and Ruby classes are interesting to me because on the outside, they seem to function very similarly, that is, they are the outer shell to a series of interrelated functions/methods/data that are instantiated and are thus able to be called repeatedly with differing data without a problem. The thing that distinguishes them for me is something less concrete and more philosophical: what kind of position they occupy in the mind of the programmer.
To me, writing a Ruby class is almost like describing and creating a real world object. A class says, "This is something, it exists, this is what it does (methods)". A constructor function is not so, because in a more basic sense, it is not syntactically different from regular functions, which would be like if Ruby classes were just another kind of method.


Eighth Week of RC
Day 3: Fun with Forms
April 10, 2019
I'm currently fixing up a pull request on OpenOversight's Find Officer Form, which starts by asking users to select a police department. The next step asks users to enter whatever they remember of the officer's badge number, last name, and their "unique internal identifier." The unique internal identifier refers to a unique number that departments use to identify officers. Different departments have different terms for this concept, which makes it hard to represent in the form. If we say "unique internal identifer," users won't know what we mean.
I decided to get around this by dynamically setting the field, and assigning it different values depending on which department users select in the form's first step. However! Whichever department the user enters in the form, which we can access with the code form.data['department']
, won't be available until the form is submitted. In order to access the department selection before the user submits the form, I use Javascript to access the form selection, like so:
let $deptSelectionId = $('#dept').val()
I was initially irritated to find that I couldn't use Python to access form data. The form.validate_on_submit()
method was so handy, I had high hopes that there'd be a similar method that didn't require submission, like form.validate()
. I also tried looking for a way to validate individual fields, but my googles proved fruitless. Lesson of the day: Stay flexible, and don't run from JQuery.

Brotherhood of Blood
Overview:
Brotherhood of Blood is the main "PvP" covenant. They can invade (both players roll dice and the side with the highest sum wins) all players once each for every death in-game.
 When you successfully invade a player, you gain a token that can be used for several benefits and interactions.
Actions and Effects
- PvP - You roll a d8 on all invasions both to attack and defend.
- Invasion (+2 Sin) - Invade a player with sins (both players rolls dice and the side with the highest sum wins).  If you lose, drink once. Can invade as many times as you want, but only once per player per death.
- Token of Spite - Gains a token of spite on each successful invasion that can be spent on several effects listed below.
Token of Spite
You can spend your tokens on these interactions anytime you want. Make sure that the other players are aware that you have spent your tokens.
- 2 tokens - Invade chosen player again this turn.
- 6 tokens - Can Invade players twice this entire round
- 10 tokens - Roll a d10 instead of your d8 for invasions (Duration: 3 rounds)
- 20 tokens - Everyone except you drinks 5

CROSSING DELANCEY A film review by actnyc!jsb Copyright 1989 actnyc!jsb
Well, I was looking forward to seeing CROSSING DELANCEY since everyone I know who saw it said they'd liked it. Supposedly, it was about how one falls in love despite rather than because of how you think it ought to be. Well, that's what MOONSTRUCK was about or at least what one of Nicholas Cage's speeches in MOONSTRUCK was about, and a good little speech it was, too. But CROSSING DELANCEY was not really about that at all. It was really about how deep down inside, every fish knows they really need a bicycle.
Okay, so here I am expecting to like this film and it starts out with Amy Irving's character Izzy (hmmm, a unisex name) in her exciting New York singles life with her literary crowd and her occasional overnight lay, with this old Jewish grandmother whom she loves but who doesn't really understand who she is. And Bubba (Yiddish affectionate term for grandma) arranges for Izzy to meet this nice Jewish man who sells pickles. (Hmmm, pickles.) I already know the plot. She's going to end up with the pickle man so what I want to see is how the film will pull it off. All the film has to do now is to get me to like this pickle guy and consider him superior to the literary types she hangs with.
Well, there are already things about the lit folks not to like. The usual faults: vanity, pretentiousness, manipulativeness, superficiality. They just know how to phrase things in an interesting manner. So we're halfway there. And we've got to overcome outdatedness, religiousness (which is, after all, outdated), drabness, uncoolness on Sam the pickle man's side. He has to become "substance" in contrast to the other folks "style." Well, his drabness can be shown to be self-assurance, i.e., he has no need to dramatize himself. His outdatedness can actually be respect for those outdated others in his community, e.g., he allows the matchmaker to believe that it was she who brought them together when actually he'd noticed Izzy two years earlier. His straight-forwardness is contrasted to the manipulations of the lit crowd and Izzy herself in her embodyment of their values.
But, for me any way, I never experience Sam as attractive. If only he would let slip that he could phrase things in an interesting manner too if he felt like it. In the Italian version, Nicholas Cage's character has an outrageousness and an energy which is attractive but Sam is just too G-rated to be exciting without some unique characteristic to make him stand out. But that's part of the message of this film. Bubba admits the man she'd married wasn't special, just persistent but that showed how much he loved her and that that was the basis of her marriage's (and therefore all marriage's) success. Attractiveness is just style, persistence is substance.
And what does Sam see in Izzy? His first attraction is to her looks. And all that he gets to see of her in the following several scenes is how good she looks and how badly she treats him. So Sam gets to chase style and ignore substance. Well, he's got enough substance for both of them. So I'm left feeling that, since her life is incomplete without a man (and we are continuously and subtly shown evidence that this is so, only she's too modern to admit it to herself) and Sam is a nice man (since he puts up with her mistreatment of him) she is right to end up with him. She doesn't understand why she is attracted to him and acts as if she is drawn to him against her will. I don't understand why she is attracted to him either and experienced the "against her will" part not as a surrender to a deeper self within her, but as a surrender to the traditional solution for what every women really needs.

2.3 The shutil Module
The shutil utility module contains some functions for copying files and
directories. The copy function used in Example 2-4 copies a file in
pretty much the same way as the Unix cp command.
Example 2-4. Using the shutil Module to Copy Files
File: shutil-example-1.py
import shutil
import os
for file in os.listdir("."):
if os.path.splitext(file)[1] == ".py":
print file
shutil.copy(file, os.path.join("backup", file))
aifc-example-1.py
anydbm-example-1.py
array-example-1.py
...
The copytree function copies an entire directory
tree (same as cp -r), and rmtree
removes an entire tree (same as rm -r). These functions are illustrated in Example 2-5.
Example 2-5.
Traceback (most recent call last):
File "shutil-example-2.py", line 17, in ?
print os.listdir(BACKUP)
os.error: No such file or directory

Chapter 1 R Markdown Basics
Here is a brief introduction into using R Markdown. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. R Markdown provides the flexibility of Markdown with the implementation of R input and output. For more details on using R Markdown see http://rmarkdown.rstudio.com.
Be careful with your spacing in Markdown documents. While whitespace largely is ignored, it does at times give Markdown signals as to how to proceed. As a habit, try to keep everything left aligned whenever possible, especially as you type a new paragraph. In other words, there is no need to indent basic text in the Rmd document (in fact, it might cause your text to do funny things if you do).
1.1 Lists
It’s easy to create a list. It can be unordered like
- Item 1
- Item 2
or it can be ordered like
- Item 1
- Item 2
Notice that I intentionally mislabeled Item 2 as number 4. Markdown automatically figures this out! You can put any numbers in the list and it will create the list. Check it out below.
To create a sublist, just indent the values a bit (at least four spaces or a tab). (Here’s one case where indentation is key!)
- Item 1
- Item 2
- Item 3
- Item 3a
- Item 3b
1.2 Line breaks
Make sure to add white space between lines if you’d like to start a new paragraph. Look at what happens below in the outputted document if you don’t:
Here is the first sentence. Here is another sentence. Here is the last sentence to end the paragraph. This should be a new paragraph.
Now for the correct way:
Here is the first sentence. Here is another sentence. Here is the last sentence to end the paragraph.
This should be a new paragraph.
1.3 R chunks
When you click the Knit button above a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this (cars
is a built-in R dataset):
summary(cars)
speed dist
Min. : 4.0 Min. : 2.00
1st Qu.:12.0 1st Qu.: 26.00
Median :15.0 Median : 36.00
Mean :15.4 Mean : 42.98
3rd Qu.:19.0 3rd Qu.: 56.00
Max. :25.0 Max. :120.00
1.4 Inline code
If you’d like to put the results of your analysis directly into your discussion, add inline code like this:
The
cos
of \(2 \pi\) is 1.
Another example would be the direct calculation of the standard deviation:
The standard deviation of
speed
incars
is 5.2876444.
One last neat feature is the use of the ifelse
conditional statement which can be used to output text depending on the result of an R calculation:
The standard deviation is less than 6.
Note the use of >
here, which signifies a quotation environment that will be indented.
As you see with $2 \pi$
above, mathematics can be added by surrounding the mathematical text with dollar signs. More examples of this are in Mathematics and Science if you uncomment the code in Math.
1.5 Including plots
You can also embed plots. For example, here is a way to use the base R graphics package to produce a plot using the built-in pressure
dataset:
Note that the echo=FALSE
parameter was added to the code chunk to prevent printing of the R code that generated the plot. There are plenty of other ways to add chunk options. More information is available at http://yihui.name/knitr/options/.
Another useful chunk option is the setting of cache=TRUE
as you see here. If document rendering becomes time consuming due to long computations or plots that are expensive to generate you can use knitr caching to improve performance. Later in this file, you’ll see a way to reference plots created in R or external figures.
1.6 Loading and exploring data
Included in this template is a file called flights.csv
. This file includes a subset of the larger dataset of information about all flights that departed from Seattle and Portland in 2014. More information about this dataset and its R package is available at http://github.com/ismayc/pnwflights14.  Merges were also done with the airports
and airlines
data sets in the pnwflights14
package to get more descriptive airport and airline names.
We can load in this data set using the following command:
flights <- read.csv("data/flights.csv")
The data is now stored in the data frame called flights
in R. To get a better feel for the variables included in this dataset we can use a variety of functions. Here we can see the dimensions (rows by columns) and also the names of the columns.
dim(flights)
[1] 52808 16
names(flights)
[1] "month" "day" "dep_time" "dep_delay" "arr_time"
[6] "arr_delay" "carrier" "tailnum" "flight" "dest"
[11] "air_time" "distance" "hour" "minute" "carrier_name"
[16] "dest_name"
Another good idea is to take a look at the dataset in table form. With this dataset having more than 50,000 rows, we won’t explicitly show the results of the command here. I recommend you enter the command into the Console after you have run the R chunks above to load the data into R.
View(flights)
While not required, it is highly recommended you use the dplyr
package to manipulate and summarize your data set as needed. It uses a syntax that is easy to understand using chaining operations. Below I’ve created a few examples of using dplyr
to get information about the Portland flights in 2014. You will also see the use of the ggplot2
package, which produces beautiful, high-quality academic visuals.
We begin by checking to ensure that needed packages are installed and then we load them into our current working environment:
# List of packages required for this analysis
pkg <- c("dplyr", "ggplot2", "knitr", "bookdown", "devtools")
# Check if packages are not installed and assign the
# names of the packages not installed to the variable new.pkg
new.pkg <- pkg[!(pkg %in% installed.packages())]
# If there are any packages in the list that aren't installed,
# install them
if (length(new.pkg))
install.packages(new.pkg, repos = "http://cran.rstudio.com")
# Load packages (thesisdown will load all of the packages as well)
library(thesisdown)
The example we show here does the following:
Selects only the
carrier_name
andarr_delay
from theflights
dataset and then assigns this subset to a new variable calledflights2
.Using
flights2
, we determine the largest arrival delay for each of the carriers.
flights2 <- flights %>%
select(carrier_name, arr_delay)
max_delays <- flights2 %>%
group_by(carrier_name) %>%
summarize(max_arr_delay = max(arr_delay, na.rm = TRUE))
A useful function in the knitr
package for making nice tables in R Markdown is called kable
. It is much easier to use than manually entering values into a table by copying and pasting values into Excel or LaTeX. This again goes to show how nice reproducible documents can be! (Note the use of results="asis"
, which will produce the table instead of the code to create the table.) The caption.short
argument is used to include a shorter title to appear in the List of Tables.
kable(max_delays,
col.names = c("Airline", "Max Arrival Delay"),
caption = "Maximum Delays by Airline",
caption.short = "Max Delays by Airline",
longtable = TRUE,
booktabs = TRUE)
| Airline | Max Arrival Delay |
|---|---|
| Alaska Airlines Inc. | 338 |
| American Airlines Inc. | 1539 |
| Delta Air Lines Inc. | 651 |
| Frontier Airlines Inc. | 575 |
| Hawaiian Airlines Inc. | 407 |
| JetBlue Airways | 273 |
| SkyWest Airlines Inc. | 421 |
| Southwest Airlines Co. | 694 |
| United Air Lines Inc. | 472 |
| US Airways Inc. | 347 |
| Virgin America | 366 |
The last two options make the table a little easier-to-read.
We can further look into the properties of the largest value here for American Airlines Inc. To do so, we can isolate the row corresponding to the arrival delay of 1539 minutes for American in our original flights
dataset.
flights %>% filter(arr_delay == 1539,
carrier_name == "American Airlines Inc.") %>%
select(-c(month, day, carrier, dest_name, hour,
minute, carrier_name, arr_delay))
dep_time dep_delay arr_time tailnum flight dest air_time distance
1 1403 1553 1934 N595AA 1568 DFW 182 1616
We see that the flight occurred on March 3rd and departed a little after 2 PM on its way to Dallas/Fort Worth. Lastly, we show how we can visualize the arrival delay of all departing flights from Portland on March 3rd against time of departure.
flights %>% filter(month == 3, day == 3) %>%

SproutCore – Testing Guidelines
This guide covers using test-driven development (TDD) techniques to develop SproutCore applications. After reading this guide, you will be able to:
- Write tests for methods to be implemented and use them to help you implement them.
- Write tests to verify that your observers fire when you expect them to.
- Write tests that verify your bindings fire when you expect them to and how to incorporate SC.RunLoop so that they will function.
- TODO: more
This guide is under construction.

Seize the moment of excited curiosity on any subject to solve your doubts; for if you let it pass, the desire may never return, and you may remain in ignorance.
Getting ahead in a difficult profession requires avid faith in yourself. That is why some people with mediocre talent, but with great inner drive, go much further than people with vastly superior talent.
It's easy to get to the point in a conversation between developers and customers.
I can develop programs to meet your needs.
If a bug occurs during program development, it is easy to correct errors by easily detecting the bug.

Open Problem - Avoiding the Union Bound for Multiple Queries
Background: Perhaps the best-studied problem in differential privacy is answering multiple counting queries. The standard approach is to add independent, appropriately-calibrated (Laplace or Gaussian) noise to each query result and apply a composition theorem. To bound the maximum error over the query answers, one takes a union bound over the independent noise samples. However, this is not optimal. The problem is to identify the optimal method (up to constant factors).
Problem 1: Is there a randomized algorithm \(M : \{0,1\}^{n \times k} \rightarrow \mathbb{R}^k\) that is differentially private1 and satisfies \[ \forall x \in \{0, 1\}^{n \times k} \quad \mathbb{E}\left[ \left\|M(x) - \sum_{i=1}^n x_i \right\|_\infty \right] \leq c \sqrt{k} \] for some constant \( c > 0\) depending only on the privacy parameters?2
Adding independent Gaussian noise to each coordinate/query yields \(c \sqrt{k \log k}\) in place of \(c \sqrt{k}\) above. Steinke and Ullman [SU17] showed that the union bound can almost be avoided and obtained \(c \sqrt{k \log \log k}\) using correlated noise. The algorithm is nonetheless based on independent Gaussian noise, with the added step of using the exponential mechanism to identify high-error answers and correct them.
Note that a \(\Omega(\sqrt{k})\) lower bound is known [BUV18, SU17]. By [BDKT12] it suffices to consider mechanisms \(M\) that add instance-independent noise. That is, \(M(x) = \sum_{i=1}^n x_i + Z\) where \(Z\) is some fixed noise distribution over \(\mathbb{R}^k\) that is independent of \(x\).
Reward: For a positive solution, an all-you-can-eat sushi dinner at a sushi restaurant of your choice. If the solution is an efficiently-sampleable distribution with a closed-form density, alcohol will be included. For a negative solution, alcohol only.3
Other related work: [DSSUV15, Vad17, AS18]. A very recent work by Ganesh and Zhao [GZ20] improves the best upper bound from \(c\sqrt{k \log \log k}\) to \(c\sqrt{k \log \log \log k}\).

Specifically, \(M\) is either 1-zCDP [BS16] with \(c\) an absolute constant or, for every \(\delta > 0\), there is an \(M_\delta\) that is \((1, \delta)\)-DP with \(c = c(\delta) = c’ \cdot \sqrt{\log (1/\delta)}\) for an absolute constant \(c’\). ↩
-
Here \(x_i \in \{0, 1\}^k \subset \mathbb{R}^k\) denotes the data vector of individual \(i\) and \(x = (x_1, x_2, \dots, x_n) \in \{0,1\}^{n \times k}\). For simplicity, we only consider expected error; high-probability error bounds are an immediate consequence. ↩

BLAST is a powerful tool that can be used to compare genetic sequences. BLAST works by comparing a genetic sequence of nucleotides (A
, C
, G
, and T
) to a database of sequences.
In the UNIX environment BLAST can easily be installed using the following code:
# Install BLAST
sudo apt-get install ncbi-blast+
Once installed BLAST can be executed from the UNIX terminal. You can either compare your sequences to all the nucleotide data available in the online databases, using the following code:
# Compare query sequences to online databases
blastn -query querySequences.fasta -out blastOutput.txt -db nr -remote
Or you can create a local database on your computer containing the sequences that you are interested in comparing your query sequences against, using the following code:
# Make local database
makeblastdb -in databaseSequences.fasta -parse_seqids -dbtype nucl
With your local database created, you can compare your query sequences against it using the following code:
# Compare sequences to local database
blastn -query querySequences.fasta -out blastOutput.txt -db databaseSequences -outfmt 0
