Webvisions Stands Up There With The Big Guys


Steven Tash as a psi-test subject in Ghostbusters, from imdb.com
In this practical, you will explore the merits of sequential analysis with a chance, at the end, to help out Bem’s to design more effective study designs.
By the end of this practical, you will know how to conduct sequential analysis using a basic example.
Open the NewStats
R project.
Open a new R script. Add your name, date, and “Sequential analysis practical” as comments at the beginning of the script.
## NAME
## DATE
## Sequential analysis practical
Save the new script as “power_analysis_practical.R” in the 2_code
folder.
Load the necessary packages. See below.
# Load packages

function to read in psi_exp_1.csv
, the data of Bem’s first experiment.# Read in data
psi <- read_csv(file = "1_data/psi_exp_1.csv")
stops
and data collection is terminated whenever a test yields a p-value smaller than alpha
. The default is stops = 2:100
, which means that beginning with a sample size of 2, the t-Test will be run after every individual observation until the final sample size is reached or the process process aborts because the p-value is smaller than alpha. Run the function definition in the console, so that you can use the function in the next step.# incremental one sample t-test simulation
simulate_sequential_onesample <- function(stops = 2:100,
alpha = .05,
mu = 0,
sigma = 1,
repeats = 1000){
stops = c(0, stops)
ps <- numeric(repeats)
ns <- numeric(repeats)
for(i in 1:repeats){
x = rep(NA, max(stops))
for(j in 1:(length(stops)-1)){
pos = (stops[j]+1):stops[j+1]
x[pos] <- rnorm(length(pos), mu, sigma)
p <- t.test(x)$p.value
if(p < alpha) break
}
ps[i] <- p
ns[i] <- stops[j+1]
}
# out
cbind("p_value" = ps, "sample_size" = ns)
}
mu
of the data is 0, which implies that any significant result is a false positive. The function returns a matrix with two columns, one for the p-values and one for the number of samples.# simulate p-values
result <- simulate_sequential_onesample()
# count significant p-values
mean(result[,"p_value"] < .05)
alpha
and try to find a value so that for default stops = 2:100
the overall number of significant results is approximately .05
.#define alpha
alpha <- XX
# simulate p-values
result <- simulate_sequential_onesample(alpha = alpha)
# count significant p-values
mean(result[,"p_value"] < alpha)
.05
. Now keep the alpha at that level and introduce a small effect with mu = .3
, which is equivalent to d = .3
, and run the simulation twice. Once with stops = 2:100
and the alpha value you have just determined, and once with stops = 100
and alpha = .05
, so that we can compare sequential and non-sequential analysis approaches. Then evaluate both the number of significant results and the number of samples taken.# simulate sequential
result_sequential <- simulate_sequential_onesample(alpha = XX,
mu = .3)
# simulate non-sequential
result_nonsequential <- simulate_sequential_onesample(stops = 100,
alpha = .05,
mu = .3)
# evaluate power
mean(result_sequential[,"p_value"] < XX)
mean(result_nonsequential[,"p_value"] < .05)
# evaluate sample sizes
mean(result_sequential[,"sample_size"])
mean(result_nonsequential[,"sample_size"])

. So this kind of sequential analysis is neither really bad, nor a real improvement. What do you think how could we do better.alpha
argument, has a new argument alphas
, which expects a numeric of the same length as stops
specifying the level of alpha used for each individual stop. Run the function definition, so that you can use it in the next step.# incremental one sample t-test simulation
simulate_sequential_proper <- function(stops,
alphas,

getDesignGroupSequential()
function from the rpact
package. Provided with some necessary inputs this functions determines for you appropriate levels of alpha for each of the testing steps that you would like to perform. Determine alphas for ten steps in a two sided design with a maximum alpha of .05
by setting alpha = .05
, informationRates = seq(.1, 1, .1)
, and sided = 2
. Print the object and try to make sense of the presented information.# determine alphas
alphas <- getDesignGroupSequential(alpha = .05,
informationRates = seq(.1, 1, .1),
sided = 2)
# print
alphas
Cumulative alpha spending
. This is the alpha values we should use to optimize the sequential analysis process, at least according to the O’Brien & Fleming approach, which is the default implemented in getDesignGroupSequential()
. As you can see an apporpiate sequence of alpha values is not composed of constant alpha values, but of very small values in the beginning and increasing larger values towards the maximum sample size planned. Extract this element containing the alpha sequence and store in an object.# determine alphas
alpha_spending <- alphas$alphaSpent
simulate_sequential_proper()
function equipped with alpha_spending
and stops = seq(10, 100, 10)
, to evaluate whether we have an false error rate of 5% in the absence of an effect (mu = 0
). Note that we are not using the same stops, since the function has a maximum number of stops of 20
. Also note that the relevant column in the output of simulate_sequential_proper()
is now called "significant"
.# simulate sequential
result_sequential <- simulate_sequential_proper(stops = XX,
alphas = XX,
mu = 0)
# evaluate power
mean(result_sequential[,"signficant"])
mu = .3
), while using alpha_spending
for the sequential approach. Set alpha of the non-sequntial approach to the false error just determined, so that everything stays comparable.# simulate sequential
result_sequential <- simulate_sequential_proper(stops = XX,
alphas = XX,
mu = XX)
# simulate sequential
result_nonsequential <- simulate_sequential_proper(stops = XX,
alphas = XX,
mu = XX)

mean(result_nonsequential[,"sample_size"])
getDesignGroupSequential()
function. For instance try out different methods to determine the alpha sequence using the type
argument.d = .1

Relevant Projects
· 3D Granular Synthesis Engine – Final year university project focussed on drawing links between an agent in a simulated emergent system (birds in a flock) and a snippet of audio in a granular synthesiser. Responsible for all audio/DSP programming using JUCE and ambisonically encoding audio output to a speaker array.
· Bus Power Board – A product developed from scratch for use by R&D teams to sit between a USB device or other power source and a host computer providing the ability to dis/connect power, data and control signals and measure time-aligned voltage, current and power. Controlled through a bespoke CLI, the device allowed for complete automation to be a feature in the test harness for commercial products.
· Castlemania – Created a 2.5D platformer game on a Cortex-M4, with a game and physics engine modelled on the original Castlevania series.

public abstract class Format extends Object implements Serializable, Cloneable
Format
is an abstract base class for formatting locale-sensitive
information such as dates, messages, and numbers.
Format
defines the programming interface for formatting
locale-sensitive objects into String
s (the
format
method) and for parsing String
s back
into objects (the parseObject
method).
Generally, a format's parseObject
method must be able to parse
any string formatted by its format
method. However, there may
be exceptional cases where this is not possible. For example, a
format
method might create two adjacent integer numbers with
no separator in between, and in this case the parseObject
could
not tell which digits belong to which number.
The Java Platform provides three specialized subclasses of Format
--
DateFormat
, MessageFormat
, and
NumberFormat
--for formatting dates, messages, and numbers,
respectively.
Concrete subclasses must implement three methods:
format(Object obj, StringBuffer toAppendTo, FieldPosition pos)
formatToCharacterIterator(Object obj)
parseObject(String source, ParsePosition pos)
MessageFormat
.
Subclasses often also provide additional format
methods for
specific input types as well as parse
methods for specific
result types. Any parse
method that does not take a
ParsePosition
argument should throw ParseException
when no text in the required format is at the beginning of the input text.
Most subclasses will also implement the following factory methods:
getInstance
for getting a useful format object appropriate
for the current locale
getInstance(Locale)
for getting a useful format
object appropriate for the specified locale
getXxxxInstance
methods for more specialized control. For
example, the NumberFormat
class provides
getPercentInstance
and getCurrencyInstance
methods for getting specialized number formatters.
Subclasses of Format
that allow programmers to create objects
for locales (with getInstance(Locale)
for example)
must also implement the following class method:
public static Locale[] getAvailableLocales()
And finally subclasses may define a set of constants to identify the various
fields in the formatted output. These constants are used to create a FieldPosition
object which identifies what information is contained in the field and its
position in the formatted result. These constants should be named
item_FIELD
where item
identifies
the field. For examples of these constants, see ERA_FIELD
and its
friends in DateFormat
.
Formats are generally not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally.

You can use the returned AttributedCharacterIterator
to build the resulting String, as well as to determine information
about the resulting String.
Each attribute key of the AttributedCharacterIterator will be of type
Field
. It is up to each Format
implementation
to define what the legal values are for each attribute in the
AttributedCharacterIterator
, but typically the attribute
key is also used as the attribute value.
The default implementation creates an
AttributedCharacterIterator
with no attributes. Subclasses
that support fields should override this and create an
AttributedCharacterIterator
with meaningful attributes.
obj

- when the Format cannot format the

The method attempts to parse text starting at the index given by
pos
.
If parsing succeeds, then the index of pos
is updated
to the index after the last character used (parsing does not necessarily
use all characters up to the end of the string), and the parsed
object is returned. The updated pos
can be used to
indicate the starting point for the next call to this method.
If an error occurs, then the index of pos
is not
changed, the error index of pos
is set to the index of
the character where the error occurred, and null is returned.

Goat Simulator is the latest in goat simulation technology, bringing next-gen goat simulation to YOU.  WASD to write history.
Last updated on: 2016-07-07 16:45
Status: in-progess
Introduction
Powered by Unreal Engine 3, Goat Simulator is the latest in goat simulation technology, bringing next-gen goat simulation to YOU.  WASD to write history. Gameplay-wise, Goat Simulator is all about causing as much destruction as you possibly can as a goat.  Destroy things with style, such as doing a backflip while headbutting a bucket through a window, and you'll earn even more points! Or you could just give Steam Workshop a spin and create your own goats, levels, missions, and more! When it comes to goats, not even the sky is the limit, as you can probably just bug through it and crash the game.

------
For the Petitioner : Mr. M.B. Lal, Advocate For the State : Mr. R.P. Singh, Addl. P.P. ------ Order No.04 Dated- 11.02.2020
Apprehending his arrest, the petitioner has moved this Court for grant of privilege of anticipatory bail in connection with Govindpur P.S. Case No.03 of 2020 registered under sections 414/34 of the Indian Penal Code, Section 4 (1) (A)/21 of M.M. (D&R) Act, 1957, Rule 4/54 of JMMC Rules, 2004, Rule 7/13 of Jharkhand Minerals (Prevention of Illegal Mining Transportation and Storage) Rules and Section 21 of Air Pollution Act, 1981.
Heard the learned counsel for the petitioner and learned Addl. P.P. for the State.
The Learned counsel for the petitioner submits that the allegation against the petitioner is that the petitioner was involved in illegal mining from closed mines by using JCB Machine. It is further submitted that the allegation against the petitioner are all false and the petitioner has been implicated in this case only on the basis of suspicion and the JCB Machine bearing registration no.JH10BL-5925 does not belong to the petitioner though it is alleged to has been used by the petitioner. It is then submitted that the petitioner is ready and willing to furnish sufficient security including cash security and undertakes to cooperate with the investigation of the case. Hence, it is submitted that the petitioner be given the privilege of anticipatory bail.
Learned Addl. P.P. opposes the prayer for grant of anticipatory bail.
Considering the submissions of the counsels and the fact as discussed above, I am of the opinion that it is a fit case where the above named petitioner be given the privilege of anticipatory bail. Hence, in the event of his arrest or surrender within a period of four weeks from the date of this order, he shall be released on bail on depositing cash security Rs.20,000/- and on furnishing bail bond of Rs. 25,000/- (Rupees Twenty Five Thousand) with two sureties of the like amount each to the satisfaction of learned J.M. 1st Class, Dhanbad, in connection with Govindpur P.S. Case No.03 of 2020 with the condition that the petitioner will cooperate with the investigation of the case and appear before the Investigating Officer as and when noticed by him and will furnish his mobile number and a copy of his Aadhar Card in the court below with the undertaking that he will not change his mobile number during the pendency of the case subject to the conditions laid down under section 438 (2) Cr. P.C.

Summary
Don't Walk By is a top-down Lemmings-inspired puzzle game. Each level has a unique layout with various hazards. The player must assign abilities to students to lead the students out of the exit to safety. This was developed by a cohort of over 40 students for the Commercial Games Development module. Art and audio assets were commissioned externally by the module leaders.
What did I do?
I implemented Z-ordering on the grid system to sort 2D sprites based on their y-position in the level. I also designed and implemented the particle systems for the fire hazards.


Hey! I Love to program in C# languange, JavaScript, Ruby and more. I also love to play musical instruments like Bass guitar, Piano and so. I write songs and compose them with my band Polyvalence.

15 Of The Best Shows You Can Stream On BritBox, Including A Classic Mockumentary
New streaming service Britbox brings together all your fave British-made TV, no matter what network created it, completely ad free. And when you hear what's on Britbox you might renege on your ban on anymore streaming services.
Channel 4, Channel 5, ITV, and the BBC have all clubbed together to serve up the very best of their excellent content. All on one platform. Britbox is a bit of a game changer, because there are so many flipping great shows for your televisual pleasure.
The service costs a very competitive £5.99 a month and has a 30-day free trial available for those keen on giving it a go.
Reemah Sakaan, ITV's group director for streaming, spoke to the BBC about the new service, explaining why it stands out from the crowd: "It's got the widest range of UK box sets of any service. Ostensibly the other streamers are US-focused so they make dramas for the US market, whereas BritBox is the faces, people and places that you know."
She also revealed there's a whole host of original content in the pipeline. Here's my list of the 15 best shows available:
1. 'The Office'
BBC Studios on YouTube
The original mockumentary-style show that became an international sensation.
Whether it's will they/won't they romances, David Brent doing an awkward dance, or colleagues driving each other round the bend, this show is where it's at. The Office was revolutionary not only because was it totally hilarious, but also all too believable.
2. 'Agatha Christie's Poirot'
Oh who doesn't love a moustachioed David Suchet mooching about with his cane solving mysteries? Suchet embodied the character of Poirot so much that IMO there's no other person for the role.
Gorgeous costumes, locations, high drama, and a lick of LOLs — perfect for a marathon streaming sesh on Sunday.
3. 'One Foot In The Grave'
Victor Meldrew became perhaps one of the most perfect representations of the "grumpy old git" that's ever been on our screens.
One Foot In The Grave has aged well and still brings serious LOLs. You'll be screaming "I don't believe it!" in no time.
4. 'Dickensian'
BBC First Australia on YouTube
BBC's Dickensian was basically a hybrid of a whole rake of Charles Dickens' most beloved works. Starring huge actors like Olivia Coleman and filled with mysteries and beautiful costumes. Ideal for a Christmas time treat.
5. 'Lost In Austen'
In Lost In Austen, a regular gal who loves Jane Austen's books finds a strange door in her flat that opens up into the world of Pride & Prejudice. Right. Not weird at all. Despite the out-there premise, you will be totally in love with how a modern gaze reinterprets the ridiculous but charming storylines of Austen's books.
6. 'Vera'
Vera is a kick-ass detective and, let's face it, one of the OG girl bosses. This show is a thriller, drama, murder mystery all rolled into one, and if you haven't tuned in already, you've been missing out. Vera also showcases the rugged beauty of the north of England in a way that'll have you booking train tickets in no time.
7. 'Absolutely Fabulous'
BBC on YouTube
The iconic comedy that will never not be hilarious. Everyone has a character they can identify with. And the clothes are to die for. Watch again and again and scream iconic lines like "but darling, is it art?" and "LA CROIX!" every five minutes.
8. 'Cold Feet'
Cold Feet revolutionised the dramedy genre like no other. The show told the story of a bunch of thirty somethings heading into adulthood. Their relationships, friendships, becoming parents, and even being widowed.
One of those shows that makes you laugh and cry in equal measure.
9. 'Not The Nine O'Clock News'
The OG hilarious satirical show that's aged like a fine wine. Starring comedy greats like Rowan Atkinson, Mel Smith, and Gryf Rhys Jones.
Proof that good quality humour is timeless.
10. 'Rev'
BBC Studios on YouTube
Another show starring the brilliant Olivia Coleman, Rev tells the story of a country Reverend living in East London, having been transplanted from an altogether more idyllic life in the British countryside. Coleman plays his wife and between them and their parishioners, this show is pretty darn funny.
11. 'Cruising With Jane MacDonald'
OK so I don't know exactly what's so addictive about watching TV host and former cruise ship singer Jane McDonald going about on cruises. But honestly, once you pop, you just can't stop.
12. 'Murder, Mystery & My Family'
This is like true crime meets historical documentary meets Who Do You Think You Are. And I swear down it's one of the best shows I've seen in a long time.
Each episode sees a person, with the help of experts, reinvestigate the trial in which their loved one was put to death for murder.
At the end there's a mock trial and the pretend judge says if he thought the case would stand up in a court of law today.
13. 'Tipping The Velvet'
Sarah Waters' incredible book was adapted for screen by the BBC in a way that's left its mark. The show is much loved by many fans of Queer film and TV.
Also there are heaps of OMG scenes that are not only entertaining but positively gasp worthy.
14. 'Jonathan Creek'
Who ever would have thought that a guy who designs magic tricks and illusions that lives in a windmill and solves murders in his free time would have been entertaining?
Duh, everyone.
15. 'Midsomer Murders'
One of the greatest of all the murder mysteries. And a county not even a great house prices and good school in the catchment area could make you keen on moving to.
Such easy viewing and perfect to watch with your parents.

Kyle Van Noy Fires Back at Tony Romo For Disrespecting Patriots Defense (TWEET)
by Darrelle LincolnKyle Van Noy hears everything.
Following the team’s 17-10 win over the Philadelphia Eagles on Sunday, the New England Patriots linebacker reacted to what he felt was a dig against the Patriots.
During the second half at Lincoln Financial Field, CBS broadcaster Tony Romo complimented the Patriots defense but said they were doing this by having relatively “no-name” players.
Word got back to Van Noy and he fired back on Twitter:
To be fair, outside of Patriots fans, not many fans around the league can name more than 2 players on that defense. That don’t seem to care as they continue to dominate.
After going down 10-0 in the 2nd quarter against the Eagles, that vaunted Pats defense didn’t allow another point for the remainder of the game.

This SRFI is currently in draft status. Here is an explanation of each status that a SRFI can hold. To provide input on this SRFI, please send email to<EMAIL_ADDRESS>. To subscribe to the list, follow these instructions. You can access previous messages via the mailing list archive.
To ease the human reading and writing of Scheme code involving binary data that for mnemonic reasons corresponds as a whole or in part to ASCII-coded text, a notation for bytevectors is defined which allows printable ASCII characters to be used literally without being converted to their corresponding integer forms. In addition, this SRFI provides a set of procedures known as the bytestring library for constructing a bytevector from a sequence of integers, characters, strings, and/or bytevectors, and for manipulating bytevectors as if they were strings as far as possible.
Binary file formats are usually not self-describing, and if they are, the descriptive portion is itself binary, which makes it hard for human beings to interpret. To assist with this problem, it is common to have a human-readable section at the beginning of the file, or in some cases at the beginning of each distinct section of the file. For historical reasons and to avoid text encoding complications, it is usual for this human-readable section to be expressed as ASCII text.
For example, ZIP files begin with the hex bytes 50 4B
which are the ASCII encoding for the characters "PK", the initials
of Phil Katz, the inventor of ZIP format. As another example,
the GIF image format begins with 47 49 46 38 39 61
,
the ASCII encoding for "GIF89a", where "89a" is the format version.
A third example is the PNG image format, where the file header
begins 89 50 4E 47
. The first byte is intentionally
non-ASCII, but the next three are "PNG". Furthermore, a PNG
file is divided into chunks, each of which contains a 4-byte
"chunk type" code. The letters in the chunk type are mnemonics
for its purpose, such as "PLTE" for a palette, "bKGD" for a
default background color, and "iTXt" for descriptive text in UTF-8.
When bytevectors contain string data of this kind, it is much more tractable for
human programmers to deal with them in the form #u8"recursion"
than in the form #u8(114 101 99 117 114 115 105 111 110)
.
This is true even when non-ASCII bytes are incorporated
into the bytevector: the complete 8-bit PNG file header can be written as
#u8"\x89;PNG\r\n\x1A;\n"
instead of #u8(0x89 0x50 0x4E 0x47 0x0D 0x0A 0x1A 0x0A)
.
In addition, this SRFI provides bytevectors with additional procedures that closely resemble those provided for strings. For example, bytevectors can be padded or trimmed, compared case-sensitively or case-insensitively, searched, joined, and split.
In this specification it is assumed that bytevectors are as defined in R7RS-small section 6.9. Implementations may also consider them equivalent to R6RS bytevectors (R6RS 4.3.4) or SRFI 4 u8vector
s, depending which kind of homogeneous vectors of unsigned 8-bit integers an implementation supports.
Most of the procedures of this SRFI begin with bytestring-
in order to distinguish them from other bytevector procedures.
This does not mean that they accept or return a separate bytestring type:
bytestrings and bytevectors are exactly the same type.
The basic form of a string-notated bytevector is:
#u8"
content"
To avoid character encoding issues within string-notated bytevectors, only printable ASCII characters (that is, Unicode codepoints in the range from U+0020 to U+007E inclusive) are allowed to be used within the content of a string-notated bytevector. All other characters must be expressed through mnemonic or inline hex escapes, and "
and \
must also be escaped as in normal Scheme strings.
Within the content of a string-notated bytevector:
\"
represents the integer 34;
\\
represents the integer 92;
| Seq. | Integer |
|---|---|
\a | 7 |
\b | 8 |
\t | 9 |
\n | 10 |
\r | 13 |
\| | 124 |
\x
followed by zero or more 0
characters, followed by one or two hexadecimal digits, followed by ;
represents the integer specified by the hexadecimal digits;
\
followed by zero or more intraline whitespace characters, followed by a newline, followed by zero or more further intraline whitespace characters, is ignored and corresponds to no entry in the resulting bytevector;
\
within a string-notated bytevector.
Note: The \|
sequence is provided so that
string parsing, symbol parsing, and string-notated bytevector parsing
can all use the same sequences.
However, we give a complete definition of the valid lexical syntax
in this SRFI rather than inheriting the native syntax of strings,
so that it is clear that #u8"ι"
and
#u8"\xE000;"
are invalid.
When the Scheme reader encounters a string-notated bytevector, it produces a datum as if that bytevector had been written out in full. That is, #u8"A"
is exactly equivalent to #u8(65)
.
A Scheme implementation which supports string-notated bytevectors may not by default use this notation when any of the write
family of procedures is called upon a bytevector or upon another datum containing a bytevector. A future SRFI is expected to add a configurable version of the write
procedure which may enable the use of this notation in this context.
The formal syntax of Scheme (defined in R7RS-small 7.1) is amended as follows.
In the definition of ⟨token⟩, after ‘| ⟨string⟩’, insert ‘| ⟨string-notated bytevector⟩’.
After the definition of ⟨byte⟩ is inserted:
⟨string-notated bytevector⟩ →
#u8"
⟨string-notated bytevector element⟩*"
⟨string-notated bytevector element⟩ → ⟨any printable ASCII character other than"
or\
⟩
| ⟨mnemonic escape⟩ |\"
|\\
|\
⟨intraline whitespace⟩*⟨line ending⟩⟨intraline whitespace⟩*
| ⟨inline hex escape⟩
(bytestring
arg …)
Converts args into a sequence of small integers and returns them as a bytevector as follows:
If arg is an exact integer in the range 0-255 inclusive, it is added to the result.
If arg is an ASCII character (that is, its codepoint is in the range 0-127 inclusive), it is converted to its codepoint and added to the result.
If arg is a bytevector, its elements are added to the result.
If arg is a string of ASCII characters, it is converted to a sequence of codepoints which are added to the result.
Otherwise, an error satisfying bytestring-error?
is signaled.
Examples:
(bytestring "lor" #\r #x65 #u8(#x6d)) ⇒ #u8"lorem"
(bytestring "η" #\space #u8(#x65 #x71 #x75 #x69 #x76)) ⇒
error
(make-bytestring
list)
If the elements of list are suitable arguments for
bytestring
, returns the bytevector that would be the
result of applying bytestring
to list.
Otherwise, an error satisfying bytestring-error?
is signaled.
(make-bytestring!
bytevector at list)
If the elements of list are suitable arguments for
bytestring
, writes the bytes of the bytevector that would be the
result of calling make-bytevector
into bytevector starting at index at.
(define bstring (make-bytevector 10 #x20))
(make-bytestring! bstring 2 '(#\s #\c "he" #u8(#x6d #x65))
bstring ⇒ #u8" scheme "
(bytevector->hex-string
bytevector)
(hex-string->bytevector
string)
Converts between a bytevector and a string containing pairs of hexadecimal digits.
If string is not pairs of hexadecimal digits, an error satisfying bytestring-error?
is raised.
(bytevector->hex-string #u8"Ford") ⇒ "467f7264"
(hex-string->bytevector "5a6170686f64") ⇒ #u8"Zaphod"
(bytevector->base64
bytevector [digits])
(base64->bytevector
string [digits])
Converts between a bytevector and its base-64 encoding as a string. The 64 digits are represented by the characters 0-9, A-Z, a-z, and the symbols + and /. However, there are different variants of base-64 encoding which use different representations of the 62nd and 63rd digit. If the optional argument digits (a two-character string) is provided, those two characters will be used as the 62nd and 63rd digit instead.
Details can be found in
RFC 4648.
If string is not in base-64 format, an error satisfying bytestring-error?
is raised.
However, characters that satisfy char-whitespace?
are silently ignored.
(bytevector->base64 #u8(1 2 3 4 5 6)) ⇒ "AQIDBAUG"
(bytevector->base64 #u8"Arthur Dent") ⇒ "QXJ0aHVyIERlbnQ="
(base64->bytevector "+/ /+") ⇒ #u8(#xfb #xff #xfe)
(bytestring->list
bytevector [ start [ end ] ])
Converts all or part of a bytevector into a list of the same length containing characters for elements in the range 32 to 127 and exact integers for all other elements.
(bytestring->list #u8(#x41 #x42 1 2) 1 3) ⇒ (#\B 1)
(make-bytestring-generator
arg …)
Returns a generator that when invoked will return consecutive bytes
of the bytevector that bytestring
would create when applied
to args, but without creating any bytevectors.
The args are validated before any bytes are generated;
if they are ill-formed, an error satisfying
bytestring-error?
is raised.
(generator->list (make-bytestring-generator "lorem"))
⇒ (#x6c #x6f #x72 #x65 #x6d)
(bytestring-pad
bytevector len char-or-u8)
(bytestring-pad-right
bytevector len char-or-u8)
Returns a newly allocated bytevector with the contents of bytevector plus sufficient additional bytes at the beginning/end containing char-or-u8 (which can be either an ASCII character or an exact integer in the range 0-255) such that the length of the result is at least len.
(bytestring-pad #u8"Zaphod" 10 #\_) ⇒ #u8"____Zaphod"
(bytestring-pad-right #u8(#x80 #x7f) 8 0) ⇒ #u8(#x80 #x7f 0 0 0 0 0 0)
(bytestring-trim
bytevector pred)
(bytestring-trim-right
bytevector pred)
(bytestring-trim-both
bytevector pred)
Returns a newly allocated bytevector with the contents of bytevector, except that consecutive bytes at the beginning / the end / both the beginning and the end that satisfy pred are not included.
(bytestring-trim #u8" Trillian" (lambda (b) (= b #x20)))
⇒ #u8"Trillian"
(bytestring-trim-both #u8(0 0 #x80 #x7f 0 0 0) zero?) ⇒ #u8(#x80 #x7f)
(bytestring-replace
bytevector1 bytevector2 start1 end1 [start2 end2])
Returns a newly allocated bytevector with the contents of bytevector1, except that the bytes indexed by start1 and end1 are not included but are replaced by the bytes of bytevector2 indexed by start2 and end2.
(bytestring-replace #u8"Vogon torture" #u8"poetry" 6 13)
⇒ #u8"Vogon poetry"
To compare bytevectors for equality, use the
procedure bytevector=?
from either
the R6RS library (rnrs bytevectors)
or
the equivalent R7RS library (scheme bytevector)
.
(bytestring<?
bytevector1 bytevector2)
(bytestring>?
bytevector1 bytevector2)
(bytestring<=?
bytevector1 bytevector2)
(bytestring>=?
bytevector1 bytevector2)
Returns #t
if bytevector1 is less than / greater than / less than or equal to / greater than or equal to bytevector2. Comparisons are lexicographical: shorter bytevectors compare before longer ones, all elements being equal.
(bytestring<? #u8"Heart Of Gold" #u8"Heart of Gold") ⇒ #t
(bytestring<=? #u8(#x81 #x95) #u8(#x80 #xa0)) ⇒ #f
(bytestring>? #u8(1 2 3) #u8(1 2)) ⇒ #t
(bytestring-index
bytevector pred [start [end]])
(bytestring-index-right
bytevector pred [start [end]])
Searches bytevector from start to end / from end to start for the first byte that satisfies pred, and returns the index into bytevector containing that byte. In either direction, start is inclusive and end is exclusive. If there are no such bytes, returns #f
.
(bytestring-index #u8(#x65 #x72 #x83 #x6f) (lambda (b) (> b #x7f))) ⇒ 2
(bytestring-index #u8"Beeblebrox" (lambda (b) (> b #x7f))) ⇒ #f

(bytestring-break #u8(#x50 #x4b 0 0 #x1 #x5) zero?)
⇒ #u8(#x50 #x4b)
#u8(0 0 #x1 #x5)
(bytestring-span #u8"ABCDefg" (lambda (b) (> b 40) (< b 91)))
⇒ #u8"ABCD"
#u8"efg"
(bytestring-join
bytevector-list delimiter [grammar])
Pastes the bytevectors in bytevector-list together
using the delimiter,
which can be anything suitable as an argument to bytestring
.
The grammar
argument is a symbol that determines how the delimiter is used, and
defaults to infix
. It is an error for grammar to be
any symbol other than these four:
infix
means an infix or separator grammar: inserts the delimiter between list elements. An empty list will produce an empty bytevector.strict-infix
means the same as infix
if the list is non-empty, but will signal an error satisfying bytestring-error?
if given an empty list.suffix
means a suffix or terminator grammar: inserts the delimiter after every list element.prefix
means a prefix grammar: inserts the delimiter before every list element.(bytestring-join '(#u8"Heart" #u8"of" #u8"Gold") #x20) ⇒ #u8"Heart of Gold"
(bytestring-join '(#u8(#xef #xbb) #u8(#xbf)) 0 'prefix) ⇒ #u8(0 #xef #xbb 0 #xbf)
(bytestring-join '() 0 'strict-infix) ⇒
error
(bytestring-split
bytevector delimiter [grammar])
Divides the elements of bytevector and returns a list of newly allocated bytevectors using the delimiter (an ASCII character or exact integer in the range 0-255 inclusive). Delimiter bytes are not included in the result bytevectors.
The grammar argument is used to control how bytevector is divided. It has the same default and meaning as in bytestring-join
, except that infix
and strict-infix
mean the same thing. That is, if grammar is prefix
or suffix
, then ignore any delimiter in the first or last position of bytevector respectively.
(bytestring-split #u8"Beeblebrox" #x62) ⇒ (#u8"Bee" #u8"le" #u8"rox")
(bytestring-split #u8(1 0 2 0) 0 'suffix) ⇒ (#u8(1) #u8(2))
(read-textual-bytestring
prefix [ port ])
Reads a string in the external format described in this SRFI
from port and return it as a bytevector.
If the prefix argument is false, this procedure assumes
that "#u8
" has already been read from port.
If port is omitted, it defaults to the value of (current-input-port)
.
If the characters read are not in the external format,
an error satisfying bytestring-error?
is raised.
(call-with-port (open-input-string "#u8\"AB\\xad;\\xf0;\\x0d;CD\"")
(lambda (port)
(read-textual-bytestring #t port)))
⇒ #u8(#x41 #x42 #xad #xf0 #x0d #x43 #x44)
(write-textual-bytestring
bytevector [ port ])
Writes bytevector in the external format described in this SRFI to port.
Bytes representing non-graphical ASCII characters are unencoded:
all other bytes are encoded with a single letter if possible,
otherwise with a \x
escape.
If port is omitted, it defaults to the value of (current-output-port)
.
(call-with-port (open-output-string)
(lambda (port)
(write-textual-bytestring
#u8(#x9 #x41 #x72 #x74 #x68 #x75 #x72 #xa)
port)
(get-output-string port)))
⇒ "#u8\"\\tArthur\\n\""
(write-binary-bytestring
port arg …)
Outputs each arg to the binary output port port
using the same interpretations as bytestring
,
but without creating any bytevectors.
The args are validated before any bytes are written to
port; if they are ill-formed, an error satisfying
bytestring-error?
is raised.
(call-with-port (open-output-bytevector)
(lambda (port)
(write-binary-bytestring port #\Z #x61 #x70 "hod")
(get-output-bytevector port)))
⇒ #u8"Zaphod"
(bytestring-error?
obj)
Returns #t
if obj is an object signaled by any of the
following procedures, in the circumstances described above:
bytestring
hex-string->bytestring
base64->bytestring
make-bytestring
make-bytestring!
bytestring-join
read-textual-bytestring
write-binary-bytestring
make-bytestring-generator
There is a sample implementation of the procedures, but not the notation, in the repository of this SRFI.
Daphne Preston-Kendal devised the string notation for bytevectors; John Cowan, the procedure library; Wolfgang Corcoran-Mathe, the sample implementation of the procedures.
The notation is inspired by the notation used in Python since version 2.6 for bytes
objects, which are fundamentally similar in purpose to Scheme bytevectors, especially in R7RS. In addition, many of the procedures are closely analogous to those of SRFI 152.
Thanks is also due to the participants in the SRFI mailing list. In particular: Lassi Kortela corrected an embarrassing technical error; Marc Nieper-Wißkirchen explained why the write
procedure ought not to be allowed to use this notation by default.

You can now load, edit and run a Stat/Transfer command processor program directly from this tab in the user interface. Typically, these will be programs that have been automatically generated by the user interface, but you can run any Stat/Transfer program from this window.
Creating a Program Automatically from the User Interface
You can generate a program for the command processor by pressing the Save Program button on the Transfer dialog box after the transfer is complete or by setting an option to activate automatic program generation.
When this program is written, it keeps all of the selections you have entered in the dialog boxes and it translates all of the options that you have specified in the Options dialog box into their equivalent command processor settings. See the section Saving a Stat/Transfer Program for details.
Creating a Program Manually
You can manually create Stat/Transfer command programs as ASCII documents. Commands are entered into the document just as they would be if you were using the command processor and entering them at the Stat/Transfer prompt. See the Command Processor section for details.
Running a Program
Begin by pressing the Open button and selecting the program you wish to use. The program will appear in the top window of the screen, where it can be viewed and, if necessary, edited. If you make any changes to the program, the Save button will become active and a Save as dialog box will allow you to save the program back to disk.
To run the program, click on the Run button. Output from the command processor will appear in the Output window. If you want to stop a program in mid-run, click on the Stop button.

An Unsupervised Generative Model
One of the most simple neural nets that serves as a generator, as opposed to a discriminator.
Encodes its input to a smaller dimension, then decodes that compressed representation to try to reconstruct the input.
Since the goal is to simply reconstruct the input, the training can be unsupervised, as the net already has the input to compare against the output.
Why reconstruct the input?
After training, the net will presumably have learned how to extract the important features of the input, and use them to recreate a convincing reconstruction.
Thus, if we pass a noisy input, the autoencoder should be able to accurately recreate the original input.
To make the autencoder more robust against certain types of noise, the noise could be added to the training samples before being passed through the net, but the output would still be compared against the original, noise-free input.

Usually, the protocol developed to analyze genome-wide replication-timing program in mammalian cells lasts 3 weeks (Ryba et al., 2011). The BrdU immunoprecipitation is a time consuming step and need to be carefully monitored in order to get most precise and specific signals. Here, we modified the previous protocol by introducing an automated step using the SX-8G IP-Star® Compact Automated System to perform the BrdU immunoprecipitation step (DNA-IP). This accelerated the protocol and improved the reproducibility of the DNA-IP experiment. Indeed, the automated system allows performing DNA-IP overnight and reduces the signal-to-noise ratio. It also provides high standardization of the DNA-IP step, allowing strong reproducibility of RT profiles from one experiment to another.
1
We first label exponentially growing cells with BrdU and fixe them. We mark cells using propidium iodide.
2
We sort cells in two fractions: early S1 and late S2 fractions with a flow activated cell-sorting system. We then extract DNA using a phenol chloroform protocol.
3
We proceed to the immunoprecipitation step with anti-BrdU antibodies and magnetic beads using the IP star robot from Diagenode.
4
The DNA obtained is then amplified and labeled with two different dyes for the early and the late fractions.
5
Same amounts of both fractions are hybridized on a DNA chip. The chip is then scanned.
6
The intensity of each probe is extracted using the Agilent feature extraction software. We finally obtain a CSV file containing the genomic coordinates and the Cy5/Cy3 ratio for each probe.
7
We use START-R analyzer and viewer.

A tennis court is a challenging environment from a robot localization perspective. Several features contribute to such a state of things:
For that reasons, many common localization techniques such as SLAM with LiDAR perform rather poorly (according to our SDP Navigation Expert). Therefore, we decided to employ a more innovative visual localization technique using a set of ArUco markers. It requires the court to be altered a bit by placing the markers around the court, but it is not intrusive as the markers can be placed outside the court itself, not interrupting the flow of the game. It does not come without any pitfalls, but supported by the fine-tuned odometry it provides a satisfactory result, that can reliably orient our system on the tennis court.
The next sections provide a more in-depth explanation of the theoretical background and our implementation of those systems.
The internal map of the environment consists of locations and poses of ArUco markers in the tennis court environment. Currently, the translation and orientation of markers, with respect to the origin of the "world" coordinate system (centre of the court), is determined during the system setup phase. The user places markers at known positions around the court and contacts our team specifying the placement of the markers so we can send them Claynce with the appropriate court map preinstalled.
In order not to over constrain the user. We do not require the exact positioning of the markers. Instead, we prepared a set of guidelines regarding the layout of ArUco markers. Following these recommendations ensures that the system behaves as efficiently as possible:
This is a temporary solution implemented in the prototype of Claynce that enabled us to create a proof of concept. In future development we would like to:
Going back to what we currently have, the translation and rotation of each marker are hardcoded in the robot's software. Each ArUco marker has a unique ID with which its positions is associated and published as a static transform from the world coordinate frame to the coordinate system of the ArUco marker.
To make the pose estimation as accurate as possible, our robot needs to see some markers. For that, we use 3 Full HD Raspberry Pi cameras. Higher-resolution helps us to more accurately determine the position of the robot with respect to the marker. We are willing to sacrifice the higher ratecenteredImg of pose estimations due to higher resolution, as the frequency is not as crucial when we have 3 cameras working simultaneously.
In our setup, two cameras are facing forward and are rotated by 30 degrees to the left and right. Such configuration allows us to reliably detect markers when moving towards markers and/or in parallel to them. One camera at the back is responsible for detecting markers when moving away from the markers.
Because it turns out that detecting markers that are at the angle to the camera gives better results. The range of marker detection of front cameras is set to 9 meters, whilst the rear one is limited to 5 meters only. The values have been set based on the results of our tests, which are presented on thee Evaluation page. This way, the position estimation error should not exceed 50 centimetres.
For the visual localisation to work, camera information and raw images are published by the device manager from ROSification library provided by Webots. The Image messages are published over a topic. A specialized node converts the messages to OpenCV frame using CvBridge tool. That frame is further processed (e.g. converting to greyscale), and ArUcos are detected. The process of marker recognition and camera -> marker transform computation is covered by OpenCV library. In the end, the frame is annotated with IDs of the markers and their bounding boxes. The modified frame is converted back to the Image message and published over a different topic for debugging purposes.
A brief overview of the implemented algorithm:
Below you can see the visual localization in action. The green arrow in the video represents the actual position of the robot. The red one is the position estimate. The axes on the top represent the positions of the markers. One can see that at the beginning the estimate is far from the actual position (estimates diverge from the actual position when the robot uses only the odometry). The moment when the camera detects markers on the wall, the pose is updated with a much more accurate estimate.
Because of the way the cameras are placed and configured, there is a "blind zone" on the court in which the robot cannot determine its position from the ArUco markers. This happens because markers on both sides of the court are too far from the robot.
Since the robot enters the blind zone after every turn away from the markers, it is important that the robot still can assess its position. For this reason, we implemented odometry as a fallback localization procedure. It is a "fallback" method in the sense that visual localization always takes precedence over odometry. Its purpose is to get the robot through the blind zone until it can again reliably detect the markers on the other side of the court.
Odometry has been implemented based on the "Odometry Kinematics" slides from Harvey Mudd College. The main parameters: wheel radius and wheel gap, have been tuned using an experimental approach. Their final values vary significantly from "theoretical" ones. But they ensure that wheel encoder readings give a reliable estimation for the forward motion and 90-degree turns. The tasks that are the most crucial for entering and leaving the blind zone. Below you can see that odometry does well when moving straight and performing ~90-degree turns, but works much worse with other turns.
Currently, Claynce supports 2 patterns that are widely used by the tennis community: zig-zag and circular. A path that the robot has to follow in a selected sweeping program is generated recursively. This makes it highly extensible to suit everyone's needs. The algorithm starts at the net and finishes at the end of the court. The path is generated for one half only and then the points for the other half are generated by reflecting the existing path in the net. This ensures two things. Firstly, that the robot starts sweeping the second half on the same side that it finished cleaning the first one. Secondly, that the robot finishes the program on the opposite half and the same side of the court on which it started the pattern. Finally, the robot gets an instruction to come back to the net so the user can pick it up.
Our algorithms are highly parametrised and very flexible to suit every user needs. Currently, we have fixed parameters for pattern generation, but in the future, we would like to expose those parameters via an app so users can create patterns that are adapted to their requirements. Regardless of the pattern, module generating paths takes into account:
The navigation algorithm is simple: the robot is given a list of (x,y) points in the court’s reference system - the points are determined from the position of the ArUco markers. Claynce knows its position on the court, and hence is able to travel to the first point on the list. Once it’s in range of that point, the list will be updated to remove it, and the robot will look at the next point to check by how much it needs to turn to reach it. This approach allows Claynce to navigate to literally any point from the list, as long as it knows its position correctly. This makes the algorithm very versatile, although right now we’re not using it to full potential - the web application allows you to choose one of two predefined patterns (either a zigzag one, or a circular one).
While the robot is moving to the next point, it is possible for it to go off-track due to friction or sliding of the wheels or maybe something else. To remedy this, there exists an angle correction algorithm: given the location of the next point and the position of Claynce on the court, it’s possible to calculate the distance between them, as well as the angle of the direction of movement (with respect to the court’s reference frame). If this calculated angle is not the same as the angle at which the robot is travelling now, Claynce will adjust its wheel velocities to turn more to the side to face the destination straight on. For example, see this image: The robot has not turned properly, meaning that the destination is not straight ahead. The algorithm calculates the angle of travel (from the set horizontal axis x) alpha, as well as the angle by how much the course needs to be adjusted (beta). Using this information and basic trigonometry, the robot changes the velocities of the wheels so that it turns right until beta reaches almost zero - it will never exactly be zero, so some tolerance (0.1 degrees) is allowed. After that it starts going straight again, because the destination is now right in front of it. This algorithm runs constantly, so the robot continuously compares the angles and adjusts its velocity if necessary.
Obstacle avoidance: Claynce has three distance sensors on the front to allow it to detect obstacles. To retain a complete clay pattern, Claynce will not take any detours in the cleaning process, but instead will stop in front of any obstacles, notify its user, and wait until they are removed. The distance sensors are placed in such a way as to detect the obstacles that are 40 cm in front, or a bit to the sides of the robot (the ones at the sides may stop the net from moving forward); hence one sensor points straight, while the other two are point at 30-degree angles from the robot’s centerline. We opted for sensors with a shorter detection range to allow Claynce stop in front of reasonably small obstacles, while ignoring the net poles or the walls of the court, which are usually farther away from it.

I am a fan of Strategy Games too, like Sim City, Command & Conquer, etc...
So, next year will come SimCity in a whole new game engine.
I guess this game is able to be one of my favo strategy games.
Today i found a new strategy video that describe a lot of features, looks amazing.

So, anybody here that love that sort of games too?
AND HOPEFULLY EA do not crack that game again, as they do with every new game.

SimCity (5), now there's a game I'm really, really, looking forward to playing. I love those kind of games and by the looks of the trailers it's going to be amazing. I can't wait for it to come...

Yes I got one. Installing right now. Weird thing, the download size is only 180MB :\
EDIT: 180MB is the installer from Origin.

You lucky. I registered to the beta few months ago, well, not helped. I hate that.
 :(
Can't wait for march !

if you pre-ordering the game you will get auto access to the beta.
a friend of mine has it and installing now too.
Haha. I've heard that the download times are pretty bad. SimCity is released on the 8th in Sweden, only a few hours to go.
If anyone here has it, does it download/load slow?

It's not loading / downloading times. It's queue that keeps you for half hour in launcher before letting you into the game :D

Uhm, I just launched Origin and apparently EA/Origin decided to release SimCity today instead in Sweden.
For some reason it says today on all online shops as well, what have I missed, lol. I swear to god that It was supposed to be on the 8th.
Oh well, I'll guess I'll boot it up and see how the queue is doing.

Well, for me it's fully downloaded and i also finished the tutorial.
But it's impossible to start a own game, server's always down when you need some online interactions.
This release is more horrible than Diablo 3 - Diablo 3 also had a lot of problems, but they fixed it a way faster.
Just crap.

Okay, I officially give this game launch the "Bulls**t Stamp of Approval".
The European servers are all full and the one server that is available is waiting for a login opportunity.
How hard can it be for a big company like EA to fix something like this?

It's the worst EA launch that I've seen so far.
The worst before this was the Battlefield: Bad Company 2 launch on the Xbox 360.

So appereantly - Amazon pulled SimCity from the store, other stores are doing the same (trying to control the flow of sold copies to steady out the server load, before allowing new players in? - wouldn't be the first time - GuildWars2 - except they didn't have such problems :))
To ease the server load, they are shutting down all non-essential components of the game.
Now I'm reading the patch notes from the latest version:
eeeeeyyyy guys... stop crying.
it's SIM CITY! And we all saw in the trailers that it will be awesome!
so please dont badmouth the game only because the start wasn't so good.
lets give them a chance.
i'm sure it will be great and good and working well =)

Ain't gonna buy it, ain't gonna play it.

Update for me, yesterday evening it worked for about 2 hours for me on the West 2 America Server.
No connection lost, no problems at all. This is how it should work.
Let's see on the weekend peak times if it will work stable.
About the game, it's actually a real Sim City feeling. But many bugs and glitches maybe make somebody angry (like me). There is a looot to do for Maxis before he can call it "final".
For me it feels that this is a full price beta test.

I've managed to play all night (took an all-nighter :S). Once I got past the connection problems (a/k/a servers being full) the game has worked fine for me. I haven't noticed any major bugs.
The one minor bug I saw was a fire truck that kept driving around the burning building until it burned down, lol.

Seems like EA wants to apologise for the problem filled launch.
And to get us back in your good graces, we’re going to offer you a free PC download game from the EA portfolio. On March 18, SimCity players who have activated their game will receive an email telling them how to redeem their free game.
Is EA softening up, or what?

Maxis probably pushed EA to do it... Besides, it'll be some worthless piece of game you'll get as an apology anyways :)

Yes, i love it. Played 6 hours to create my first cool city with about 25k people.
Than, oops, can't synchronize your city with the server, we try to fix it. What happened? City deleted.

I've only had problems with joining the servers from time to time, and occasionally a few minor bugs. Never lost a city or anything like that.
The thing that annoys me the most is the city size, I mean, I can't fit anything in there... I want a huge chunk of land to play around on.
It makes me feel limited in what I can do.
Overall I like the game, it's really fun.
The only
major/big
drawbacks would be the problem filled launch and the city size.

So, played round about 20 hours and my motivation is gone.
The extremely small size of cities is not that what i want from a sim city.
The problem with the regions is that you must begin again, and again, and again...
Boring, no challange.
I tried to built from the start with 3 regions, 1 for green, 1 for blue and 1 for yellow fields.
Not possible, you need in every city all 3 to get it working.
If the game costs 30€ it is ok, but for 60€ it's a way to expensive for this experience, in my opinion.

Doesn't seem like we're alone. Pretty much everyone on the SimCity forums want a bigger playable area.
I hope they release an update for it.
