VAMPIRE IN BROOKLYN A film review by James Berardinelli Copyright 1995 James Berardinelli
RATING (0 TO 10): 5.1
United States, 1995 U.S. Availability: 10/27/95 (wide) Running Length: 1:40 MPAA Classification: R (Profanity, violence, gore) Theatrical Aspect Ratio: 1.85:1
Cast: Eddie Murphy, Angela Bassett, Allen Payne, Kadeem Hardison, John Witherspoon Director: Wes Craven Producers: Eddie Murphy and Mark Lipsky Screenplay: Charles Murphy, Michael Lucker, and Chris Parker Cinematography: Mark Irwin Music: J. Peter Robinson U.S. Distributor: Paramount Pictures
It seems that movie makers have lost the art of creating a good, scary vampire flick. The last such film to grace the screen was probably FRIGHT NIGHT, and that was a decade ago. Since then, the "sensitive" vampire has come into vogue--a creature tortured by its own inhumanity and appetites. While these existential nightstalkers have an appeal as character studies, they aren't all that frightening. True evil, of the absolute, soulless kind, is what makes for a terrifying bloodsucker. Unfortunately, that's not exactly what VAMPIRE IN BROOKLYN offers.
To be fair, Eddie Murphy does a better-than-average job as Maximillian, the last vampire on Earth. There are moments when Murphy is positively chilling, and he doesn't ham it up too much. Comedy is mixed in effectively, but it's what the humor is mingled with that doesn't work. As a horror film, VAMPIRE IN BROOKLYN is a failure. Aside from Murphy's creature, there's nothing compelling in this picture. The script is dull, the characters are flat, and the direction is rather ordinary. (This is especially surprising considering that horror master Wes Craven, who did the first and last NIGHTMARE ON ELM STREETs, is at the helm.)
Maximillian makes his entrance to Brooklyn by crashing a ship into the docks. On board are numerous corpses, all drained of blood. A huge wolf is seen disembarking, but no one believes the eyewitness. Next thing, there's a vampire roaming the streets, feeding on gangsters and recruiting a young thief/con man (Kadeem Hardison) as his ghoulish servant. But Max is in New York for a reason--he's on the trail of the only other member of his kind, the offspring of a vampire/human mating, a woman whose "other half still sleepwalks in humanity." He intends to bring out her true nature and introduce her to immortality. The person in question happens to be Rita Veder (Angela Bassett), a police officer assigned to investigate the murders on the ship that brought Max to the United States. And the vampire isn't the only one interested in her. Her partner, Justice (Allen Payne), is equally smitten.
The hero is supposed to be Justice, but Allen Payne's portrayal lacks energy. The result is a bland and unsympathetic character. Why should we care about this guy? Instead, our attention gravitates to Murphy, the only performer attacking his role with relish. Thus, as in all recent vampire movies, it's the villain, not the good guy, who keeps us interested. And Max isn't really such a bad seed--he's just lonely and misunderstood. The centuries can turn tedious without a mate to share them with. There's some chemistry between Murphy and Bassett, but absolutely none in the Bassett/Payne pairing. Yet both relationships get equal screen time.
There are a few comic highlights. One occurs when Max shape-shifts into an Al Sharpton-type preacher who gives a sermon on how "evil is good." Here, as the script ventures into pure satire, it acquires an edge that is absent most of the rest of the time. Also, some of the interplay between Julius (Hardison) and his older buddy Silas (John Witherspoon) is witty, and worthy of a few laughs. This pair does a great "Two Stooges" act.
Overall, however, VAMPIRE IN BROOKLYN doesn't live up to its promise or premise. The humor is hit-and-miss and the horror just isn't all that frightening. Eddie Murphy proves that he still has screen presence, but he needs a better showcase. The problem here isn't as much the talent in front of the camera as it is the weak and hackneyed script. VAMPIRE IN BROOKLYN is in need of an infusion (or should that be transfusion?) of originality and creativity--two qualities that are blatantly absent.

New Delhi: In a gesture that will strengthen India’s relationships with the United Arab Emirates, the Centre is now offering visa-on-arrival facility for UAE nationals travelling to India. The facility will be available to UAE nationals for a period of up to 60 days with double entry for business, tourism, conference and medical purposes. This facility will be available at six international airports: Bangalore, Chennai, Delhi, Hyderabad, Kolkata and Mumbai.
“Government of India, with effect from November 16, 2019, has decided to extend the Visa-on-Arrival facility to nationals of the United Arab Emirates,” a statement from the embassy said, which was retweeted by the Indian ambassador to the UAE Pavan Kapoor.
“A special gesture for the UAE with whom India has a comprehensive strategic partnership. Privileged to assume charge. Hope to further strengthen the warm India-UAE relations.,” the ambassador tweeted.
Visa-on-Arrival will be available only to those UAE nationals who have earlier obtained an e-Visa or a normal paper Visa for India, irrespective of whether the person actually visited India or not. Those UAE nationals going to India for the first time may be advised to apply for e-Visa or a normal paper Visa.
Pakistan-origin UAE nationals will not be eligible for Visa-on-Arrival Scheme. Nationals of Japan, South Korea are also eligible for the facility.

Generator Tricks for Systems Programmers - Version 2.0
Copyright (C) 2008
David M. Beazley
http://www.dabeaz.com
Presented at PyCon UK 2008, September 12, 2008.
Introduction
This tutorial discusses various techniques for using generator functions and generator expressions
in the context of systems programming. This topic loosely includes files, file systems, text parsing,
network programming, and programming with threads.
Support Data Files
The following file contains some supporting data files that are used by the various
code samples. Download this to your machine to work the examples that follow.
This download also includes all of the code samples that follow below.
Code Samples
Here are various code samples that are used in the course. You can
cut and paste these to your own machine to try them out. The order in
which these are listed follow the course outline. These examples are
written to run inside the "generators" directory that gets created
when you unzip the above file containing the support data.
Part 2 : Processing Data Files
- nongenlog.py. Calculate the number of bytes
transferred in an Apache server log using a simple for-loop. Does not use generators.
- genlog.py. Calculate the number of bytes
transferred in an Apache server log using a series of generator expressions.
- makebig.py. Make a large access-log file for performance testing. This will create a file "big-access-log". For the numbers used in the
presentation, I used python makebig.py 2000.
Part 3 : Fun with Files and Directories
- genfind.py. A generator function that yields
filenames matching a given filename pattern.
- genopen.py. A generator function that yields
open file objects from a sequence of filenames.
- gencat.py. A generator function that concatenates
a sequence of generators into a single sequence.
- gengrep.py. A generator that greps a series of lines for
those that match a regex pattern.
- bytesgen.py. Example that finds out how many bytes
were transferred for a specific file in a whole directory of log files.
Part 4 : Parsing and Processing Data
- retuple.py. Parse a sequence of lines into a
sequence of tuples using regular expressions.
- redict.py. Parse a sequence of lines into a
sequence of dictionaries with named fields.
- fieldmap.py. Remap fields in a sequence of
dictionaries.
- linesdir.py. Generate lines from files in a directory.
- apachelog.py. Parse an Apache log file.
- query404.py. Find the set of all documents that
are broken (404).
- largefiles.py. Find all requests that transferred over a megabyte.
- largest.py. Find the largest document.
- hosts.py. Find unique host IP addresses.
- downloads.py. Find number of downloads of a
specific file.
- robots.py. Find out who has been hitting robots.txt.
- robotsfast.py. Find out who has been hitting robots.txt (faster version).
Part 5 : Processing Infinite Data
- follow.py. Follow a log-file in real-time like tail -f in Unix. To run this program, you need to have a log-file to work with. Run the program runservers.py to start a
simulated web-server. This will write a series of log lines for you to follow.
- realtime404.py. Print all 404 requests as they
happen in real-time on a log file.
Part 6 : Feeding the Pipeline
Part 7 : Extending the pipeline
- genpickle.py. Turn sequences of objects into a sequence of pickles.
- sendto.py. Send a sequence of items to a remote
machine via a socket. Uses genpickle above.
- receivefrom.py. Receive a sequence of
items from a socket. Uses genpickle above.
- genqueue.py. Consume items on a queue.
Part 8 : Advanced Data Routing
- genmultiplex.py. Multiplex many different generators into a single real-time stream using threads.
- broadcast.py. Broadcast a sequence of items
to a collection of consumers.
- netsend.py. Send items to another host on the network. Requires a receiver (use receivefrom.py above).
- consthread.py. Broadcasting a generator to a collection of consumer threads.
Part 9 : Various Programming Tricks (And Debugging)
- gentrace.py. Example of debugging a generator component.
- storelast.py. Store the last value of a generator (for access later in the processing pipeline)
- genshutdown.py. Simple example of shutting down
a generator.
- shutdownevt.py. Shutting down a generator with an event.

<EMAIL_ADDRESS>Hello, my name is Mohammad and I am a computer science major. This will be my last semester here at Lewis before I graduate in December. I am big into video games and watching anime. I mostly play computer games, although I did grow up playing playstation. I watch anime which is basically Japanese cartoons, but more serious ones with life lessons in them. Anime will sometimes have some deep meaning within a character that will make you wonder if they are really the bad guys. I am the youngest of 5. I have 3 older brothers and an older sister. I currently work with one of my brothers at his tobacco shop.
What I really want to learn from this class is node.js. I have already taken a class with you where we made html and css web pages, but never got in depth with node.js. I want to learn how to make a fully functioning website that you can host from your computer. All html applications I have done were hosted in azure.
My favorite hobby would have to be playing video games. Video games can cover all sorts of avenues from adventure, to problem solving, to team work, etc. Anything that has a competitive aspect to it will get me hooked. I play to have fun first, but also to get better at the game and having the competitive aspect of it will make you better. The game that I have played the most is called Dota 2. The category is called moba which stands for massive online battle arena. It is a 5vs5 online game and you fight the other team to level up and get stronger and the way to win is to destroy the enemies base. I can also lose myself in adventure/story games. Some games will make you forget what is happening outside and just focus on you and the game you are playing.
Fun Fact: Last year during the pandemic I started to make custom shirts and sweaters. Basically if you have an image or idea that you want on some clothing I can do it. I have made myself multiple shirts and made sweaters for my friends. The way I do it is called HTV, or heat transfer vinyl.


RegisterGradient
A decorator for registering the gradient function for an op type.
tf.compat.v1.RegisterGradient
tf.compat.v2.RegisterGradient
This decorator is only used when defining a new op type. For an op
with m
inputs and n
outputs, the gradient function is a function
that takes the original Operation
and n
Tensor
objects
(representing the gradients with respect to each output of the op),
and returns m
Tensor
objects (representing the partial gradients
with respect to each input of the op).
For example, assuming that operations of type "Sub"
take two
inputs x
and y
, and return a single output x - y
, the
following gradient function would be registered:
@tf.RegisterGradient("Sub") def _sub_grad(unused_op, grad): return grad, tf.negative(grad)
The decorator argument op_type
is the string type of an
operation. This corresponds to the OpDef.name
field for the proto
that defines the operation.
__init__
__init__(op_type)
Creates a new decorator with op_type
as the Operation type.
op_type
: The string type of an operation. This corresponds to the
OpDef.name
field for the proto that defines the operation.TypeError
: If op_type
is not string.__call__
__call__(f)
Registers the function f
as gradient function for op_type
.


public NetworkMapCache
A network map contains lists of nodes on the network along with information about their identity keys, services they provide and host names or IP addresses where they can be connected to. The cache wraps around a map fetched from an authoritative service, and adds easy lookup of the data stored within it. Generally it would be initialised with a specified network map service, which it fetches data from and then subscribes to updates of.

Alkabitius Dominko Loves You
WARNING: The lesson which I learned from Salvia may be considered offensive. It is politically and socially incorrect. You are reading this report of your own free will.
SUBSTANCE(S) : Salvia divinorum (tincture)
DOSE : 4 droppers straight / sublingual, 15 mins.
BODY WEIGHT : 126 lb.
GENDER : Male
PREAMBLE
This is an account, as nearly as I can describe it, of my fourth experience with S. divinorum. It is an account of the results of the Sage Goddess Emerald Essence tincture manufactured and sold by Daniel Siebert. It has been divided into a preamble, an introduction, two chapters, my conclusions, and a lesson from the S. divinorum collective. This division is for organization and convenience.
I must make it clear at the outset that, as of this writing, I am still a neophyte psychonaut. Never have I ingested any recreational or spiritual psychoactive of any sort, other than S. divinorum. Being in full awareness of the intensity of the experiences which are often evoked by this psychoactive, nevertheless, I freely and willingly ingested S. divinorum.
INTRODUCTION
On this particular expedition, for which I again chose to forego the bother of a sitter, I became so daring as to ingest such a large ammount for my sensitive faculties that I passed through the second highest doorway and entered the dissociation of the immaterial existance of Salvia level five. It is also possible that I momentarily experienced the amnesia of Salvia level six, for, as the careful reader will note, there is no account of how I moved from the experiences in chapter one to those in chapter two: I have no memory of what happened during the moments between these points.
CHAPTER ONE
Cornpone pig-huggers on the mud farm.
Pacing back and forth, flanked by my couch on one side and my entertainment center on the other, I struggled to hold the four straight dropper-fulls of S. divinorum tincture in my burning mouth. My house was quaking wildly, but, strangely, my balance and muscular control remained intact.
 The lady was three-dimensional, but her husband was a plastic, two-dimensional image. They were visible from the shoulders up. Both of them were living cartoon paintings hanging in the air without a canvas: they were transparent and painted on space, or rather, the space of my mind hanging in the air.
My sense of identity was no longer what it should have been, and it was becoming even stranger.   Thet's the way! Bob yer head!'
I was fast becoming one of the folks. Sacred corn husks decorated my overalls. I was the Kangaroo God. I was the Corn God. I had the unnerving desire to walk into my mother's bedroom where she was sleeping, and announce my divinity. Fortunately, I did not do that.
I was traveling to the big extradimensional cornpone farm, with barns and tractors and picket fences, where hokey cartoon farmers grow mud and hug their pigs. The transformation of reality was banging and swaying inside my head, coming from somewhere higher up, some place I couldn't identify.
I succeeded in holding the tincture in my mouth until I lost all control.
CHAPTER TWO
God's name is Alkabitius Dominko.
I was one of the race of Giant Machines. I had all the advantages and limitations of a machine. I thought machine-thoughts, and knew only machine-pleasures and machine-duties. I was not human in any way. I did not remember having been human. I didn't even know what humans were.
Unified in mind and purpose, we, The Giant Machines, worked The Gardens. We preserved the Robot-Flower and Flower races, our relatives and helpers. Work was our existance, it was the Highest Purpose, it was all we knew and cared about. We worked and clipped and processed and danced in this colorful garden of labour under the Work Director, Alkabitius Dominko. An exhalted robot and The Great Giant Machine, Alkabitius Dominko was our master, and we served under Him, as the Aeons passed and passed away. And we were happy.
Awareness of my surroundings slowly began to return. I witnessed one of The Giant Machines towering over my body as I lay on my couch. It was being run by some unearthly creature which I cannot describe. The Giant Machine was clipping the fractal grass growing out of space, and I watched in a dreamlike stupor.
Believing that I was still waiting for the fifteen minute oral ingestion period to pass, I jumped up and wondered aloud, 'is it time?' I discovered that somehow, at some point, I had turned off the hanging lamp in my living room. I turned it on again, to discover that I'd lost so much muscular control that, in so turning on the lamp, I inadvertantly slammed it against the wall. Looking at the clock, I realized I had been disassociated from myself for only ten minutes. It had seemed like an eternity.
Everything was rolling and quaking in the rocketing spaceship which was my house. I struggled to remain upright so I could turn the light off again. My mind was sloshing and waving, drowning under the waters of dimentia, and my identity began to slip once more.
A Giant Machine Work Director from the factory-funhouse next to The Gardens had come to meet me, and was coaxing me to return. 'That's right, turn off the light. You must come back to work. Alkabitius Dominko wants you to come back to work for him!' To so deviate from our machine-natures and machine-duties as I had done, was to defy our Natural Existance as Giant Machines.
The desire to fulfill my sacred duty to Alkabitius Dominko and The Giant Machine race was overwhelming, but I recognized that my true nature was as a human, and I did not wish to return. But the S. Divinorum experience was overpowering, and I remained on the planet of the Giant Machines to have sexual intercourse, another form of work, with one of the Robot Flower race, who was far happier about the banging, bouncing, monotonous experience than I was.
The S. divinorum journey faded within ninety minutes, and I returned to earth. The rocketing spaceship had landed. I returned from the dimentia. It was good to be myself again.
I discovered a stain of tincture on the collar of my white shirt the next morning.
CONCLUSIONS
A powerful dissociative.
It had not been my intention to have a full dissociative identity transformation. But by the time I was bobbing my head and wearing sacred corn husks and thinking I was still in control, I definitely did not know what I was doing. I'm glad that the whole experience lasted only two hours.
S. divinorum is not a substance to take lightly. It is a powerful dissociative. High doses could place an individual in physical danger and psychological emergency.
If you are considering S. divinorum, I would caution against it. My experience with deep meditation may be the only thing that is responsible for my preexisting ability to cope with extradimensional space. I do not and cannot recommend high doses of S. divinorum to other first-time psychonauts.
LESSON FROM THE S. DIVINORUM COLLECTIVE
Alkabitius Dominko loves you.
People are happy to be dead-minded, following the demon Alkabitius Dominko without question or cause, revering leaders as though they were gods. Those people who awaken or are revived out of the collective trance to become human, are treated as though they need Correction. They must return to their mindless machine-state and be like everybody else, because Giant Machines are What We Truly Are. Enlightenment is given lip-service in our society, but to truly and honestly enter a higher state and become a higher entity is deviation. And deviation from the direction of Alkabitius Dominko is An Unnatural Thing.
If you want to be unique, then you are permitted to be unique, but only within a socially accepted context: you must be unique only in The Accepted Ways that everybody else is allowed to be unique. If you want something, then you are permitted to have it, but only within the social normalcies: you can have what you desire only in The Accepted Ways that other people are permitted to have that same thing, and only if it's commonly accepted in some circle. If you want to evolve, then you are permitted to evolve, but only along the path of the social collective: you must evolve into greater Giant Machines only.
This is the disease of restriction we call Culture. Many people believe they are above this problem and do not participate in it, but mindlessness is mindlesness. People who think they are above it for what ammounts to nothing more than being mindless in a different way, are the most ignorant of the slaves in The Gardens of Alkabitius Dominko.
What happens to those of us who refuse to be machines? My experience has been that we are cut off from life and pleasure as and because people discriminate against us. This is a new form of the very old fallacy of excommunication: if you're not a part of the high-tech mindlessness people refer to as Culture, then you're an idiot, or something to ignore, or another neurotic in need of treatment.
There is nothing evil about The Giant Machines, and they do their work very well, but these people are not interested in facing the truth about evolution and enlightenment. Why should something which is essentially a machine, want to evolve into a human? Machines don't even know what humans are. Machines cannot receive enlightenment.
This is what people are today. There is no logic in them. You cannot reason with the dead-minded Giant Machines. In the past people would make-up excuses for things, but people are so mindless today that excuses for staying mindless are irrelivant: you simply do not deviate or become unique, because those are things you simply do not do. And should you do them, you are wrong, and you should return to your previous state and way of thinking. This is the only way to please Alkabitius Dominko.
If people cannot or do not want to ascend, then let them stay at the lower levels. Perhaps the rest of the world is not meant to be anything more than Giant Machines. As for those of us who have awakened, we have no need to return to the lower levels.

Compiler changes
- Implement DIP 1010 - Static foreach
Support for static foreach has been added.
static foreach is a conditional compilation construct that is to foreach what static if is to if. It is a convenient way to generate declarations and statements by iteration.
import std.conv: to; static foreach(i; 0 .. 10) { // a `static foreach` body does not introduce a nested scope // (similar to `static if`). // The following mixin declaration is at module scope: mixin(`enum x` ~ to!string(i) ~ ` = i;`); // declares 10 variables x0, x1, ..., x9 } import std.range: iota; // all aggregate types that can be iterated with a standard `foreach` // loop are also supported by static foreach: static foreach(i; iota(10)) { // we access the declarations generated in the first `static foreach` pragma(msg, "x", i, ": ", mixin(`x` ~ to!string(i))); static assert(mixin(`x` ~ to!string(i)) == i); } void main() { import std.conv: text; import std.typecons: tuple; import std.algorithm: map; import std.stdio: writeln; // `static foreach` has both declaration and statement forms // (similar to `static if`). static foreach(x; iota(3).map!(i => tuple(text("x", i), i))) { // generates three local variables x0, x1 and x2. mixin(text(`int `,x[0],` = x[1];`)); scope(exit) // this is within the scope of `main` { writeln(mixin(x[0])); } } writeln(x0," ",x1," ",x2); // first runtime output }
- -betterC enhancements
Many improvements were added to the dmd's -betterC implementation, most notably programs compiled with -betterC will no longer reference unused druntime symbols, asserts are implemented as C <assert.h> calls, and phobos is not linked by default.
See the Better C specs for more details.
- AVX2 was added as -mcpu=avx2 architecture.
This allows the backend to emit AVX2 instructions. The compiler will add the predefined version D_AVX2. AVX2 support is automatically detected with -mcpu=native.
- Fix Issue 17697 - Ddoc: automatically highlight URLs outside of macro arguments
URLs which appear in Ddoc text:
/**** * http://www.fooa.com/test1 */
will be treated as if they were written:
/**** * $(LINK http://www.fooa.com/test1) */
and a clickable hyperlink will be emitted to the resulting .html file.
This detection does not happen if the URL is part of a macro argument:
/**** * $(DOLLAR)$(LPAREN)ABC http://www.fooa.com/test1$(RPAREN) */
The behavior of that is unchanged. URLs can start with http:// or https://
http: and https: at the beginning of the line are no longer treated as section headings.
Runtime changes
- Print unhandled exception's trace and abort if rt_trapExceptions is false
D exception handling was assuming the top level exception handler, so all exceptions would be handled somewhere. In case rt_trapExceptions is cleared, this handler would not be enabled, and this assertion would fail, aborting the program, but without any information about the exception. This is now changed, so the exception information will be printed to the stderr, followed by abort.
Library changes
- Base64URLNoPadding (URL-safe Base64 without padding) was added
std.base64.Base64URLNoPadding allows encoding/decoding without padding:
import std.base64 : Base64URLNoPadding; ubyte[] data = [0x83, 0xd7, 0x30, 0x7b, 0xef]; assert(Base64URLNoPadding.encode(data) == "g9cwe-8"); assert(Base64URLNoPadding.decode("g9cwe-8") == data);
- std.digest.digest was renamed to std.digest.
Motivation:
The fully qualified name of the digest function template was std.digest.digest.digest. This is because std.digest is a package, with a module named digest in it, and the function digest inside that.
std.digest contains the former std.digest.digest package.
- std.meta.Stride was added
std.meta.Stride allows selecting a subset of template by a step size and offset:
alias attribs = AliasSeq!(short, int, long, ushort, uint, ulong); static assert(is(Stride!(3, attribs) == AliasSeq!(short, ushort))); static assert(is(Stride!(3, attribs[1 .. $]) == AliasSeq!(int, uint)));
- Config.detached flag for spawnProcess has been added
Config.detached allows spawning processes which run independently from the current process. There is no need to wait on the processes created with this flag, and no zombie process will be left after they exit. Attempts to call std.process.wait or std.process.kill on detached processes will throw.
- std.range.chunks was extended to support non-forward input ranges.
Now std.range.chunks can be used with input ranges that are not forward ranges, albeit with limited semantics as imposed by the underlying range.
import std.algorithm.comparison : equal; int i; // The generator doesn't save state, so it cannot be a forward range. auto inputRange = generate!(() => ++i).take(10); // We can still process it in chunks, but it will be single-pass only. auto chunked = inputRange.chunks(2); assert(chunked.front.equal([1, 2])); assert(chunked.front.empty); // Iterating the chunk has consumed it chunked.popFront; assert(chunked.front.equal([3, 4]));
- std.socket.UnixAddress now supports abstract addresses.
UNIX domain sockets are usually identified by pathnames. Linux offers a non-portable extension to this scheme, known as abstract socket addresses, which are independent of the filesystem. An abstract socket address starts with a null byte ('\0'), e.g.:
auto addr = new UnixAddress("\0/tmp/dbus-OtHLWmCLPR");
- Added possibility to use a baseclass when auto-implementing an interface
A second std.typecons.AutoImplement template has been added, which differs from the existing one in accepting an extra type parameter. The extra parameter specifies a class to derive from while auto-implementing an interface.
The base class used may contain non-default constructors. Matching constructors will be created in the auto-implemented class and be implemented as just a call to super with all arguments.
Tools changes
- rdmd now checks for a D compiler binary in the directory it's in first
If you downloaded a zip/tar file with the compiler before and ran rdmd, it would invoke the D compiler from the system PATH rather than the compiler right next to it, failing if there wasn't one in the PATH. rdmd will now try to use the D compiler next to it first, and only fall back to the PATH if there isn't one adjacent. If you want rdmd to run a specific compiler, add the --compiler flag to force it, as always.
To restore the old behaviour of only using the compiler from your PATH, add --compiler=dmd (or ldmd2 or gdmd).

--- layout: post title: Tribe - Futures and Timers comments: false share: false date: 2013-05-25 type: post tags: - concurrency - ruby - threading - tribe - workers ---
I've added a few missing features to Tribe- Timers and Futures.
Timers provide a way to tell an actor to do something in the future. Tribe supports both one-shot and periodic timers so I believe all the major usage patterns are covered. Adding this feature was fairly easy since all of the low level details are hidden in my Workers gem.
Futures make it easy for an actor to ask another actor to perform an operation and return the result. Previously you would have to use custom events and a lot of boilerplate code to accomplish this. Both synchronous (blocking) and asynchronous (non-blocking) futures are supported. More information on both types can be found in the readme file.

[Gecode] New constraint: lex for lexical ordering
Christian Schulte
schulte at imit.kth.se
Tue Nov 9 09:58:08 CET 2004
Dear all,
Gecode features now lex as a new global constraint expressing
lexical order amoung two sequences (arrays) of variables.
The constraint is posted by
lex(home, x, r, y)
where home refers to the home space, x and y are arrays of
integer variables of same length and r is an inequality relation
(that is: REL_LQ, REL_LE, REL_GR, REL_GQ). It enforces that x and
y are lexicographically ordered with respect to r.
The propagator for lex is domain-consistent (but only bounds for
subsumtion). Each invocation costs O(n) in the worst case,
however typically it will be much better as it aggressively
eliminates assigned variables and variables known to be not any
longer relevant for decision (those that occur after a pair of
variables which are strictly ordered).
The constraint is useful (example will come) for symmetry breaking
in matrix models.
Cheers
Christian
The algorithm is from:
* This propagator uses the algorithm (and also the automaton)
* from:
* Mats Carlsson, Nicolas Beldiceanu, Revisiting the
* Lexicographic Ordering Constraint. SICS Technical
* Report T2002:17, SICS, Sweden, 2002.

EUR/JPY Technical Analysis: Weekly upside limited around 120.70
by Pablo Piovano- EUR/JPY remains sidelined so far this week below the 121.00 handle.
- US-China trade effervescence keeps weighing on the cross.
EUR/JPY remains within a multi-session consolidative theme and seems to be tracking the performance of the 21-day SMA, today at 120.43.
The inability of the cross to break above the current consolidation in the short-term carries the potential to spark a move lower with the immediate target at the 119.53/24 band, where coincide the 100-day and 55-day SMAs as well as monthly lows.
In order to alleviate the immediate downside pressure, the cross needs to overcome weekly highs around 120.70. Further up aligns the critical resistance in the 121.50 region.

Hi everyone,
I have a bare project (with mathlib imported) in which the following code
import data.nat.prime tactic.norm_num lemma prime_seven : nat.prime (7 : ℕ) := by norm_num
displays the error 'norm_num failed to simplify'. Does it work for you?
Best,
Bruno
I get no errors on my system. What version of mathlib are you using? Do other primes like 2, 3 work?
If you click on norm_num
to go to the definition, search in that file for a function called eval_prime
If you don't have it, chances are you are running an old version of mathlib
Oh, is this the 3.4.1 branch issue again?
oh, that might be it
go into _target/deps/mathlib
and git checkout master
then lean --make
(which will take a while)
yeah, no eval_prime
. Then I should be really using an old version of it.
Thanks! I'm fixing the build, I think it should work now.
It works now. Thanks, Bryan and Mario!

Man power? That's clearly the first.
If somebody more knowledgeable than me about GPUs wants to volunteer, I'll
help. But honestly, I cannot see whether propagation has the right
properties for execution on GPUs.

Let $X_{1},X_{2},\ldots$ be i.i.d random variables (independent random variables each having the same marginal distribution). Assume that the second moment of $X_{1}$ is finite. Then, $\mu=\mathbf{E}[X_{1}]$ and ${\sigma}^{2}=\mbox{Var}(X_{1})$ are well-defined.
Let $S_{n}=X_{1}+\ldots +X_{n}$ (partial sums) and $\bar{X}_{n}=\frac{S_{n} }{n}=\frac{X_{1}+\ldots +X_{n} }{n}$ ( sample mean). Then, by the properties of expectation and variance, we have $$ \mathbf{E}[S_{n}]=n\mu, \mbox{Var}(S_{n})=n{\sigma}_{1}^{2}, \qquad \mathbf{E}[\bar{X}_{n}]=\mu, \mbox{Var}(\bar{X}_{n})=\frac{{\sigma}^{2} }{n}. $$ In particular, $\mbox{s.d.}(\bar{X}_{n})={\sigma}/\sqrt{n}$ decreases with $n$. If we apply Chebyshev's inequality to $\bar{X}_{n}$, we get for any $\delta > 0$ that $$ \mathbf{P}\{|\bar{X}_{n}-\mu|\ge \delta\}\le \frac{{\sigma}^{2} }{\delta^{2}n}. $$ This goes to zero as $n\rightarrow \infty$ (with $\delta > 0$ being fixed). This means that for large $n$ the sample mean is unlikely to be far from $\mu$ (sometimes called ''population mean''). This is consistent with our intuitive idea that if we toss a $p$-coin many times, we can get a better guess of what the value of $p$ is.
Weak law of large numbers (Jacob Bernoulli) : With the above notations, for any $\delta > 0$, we have $$ \mathbf{P}\{|\bar{X}_{n}-\mu|\ge \delta\}\le \frac{{\sigma}^{2} }{\delta^{2}n}\rightarrow 0 \mbox{ as }n\rightarrow \infty. $$
This is very general, in that we only assume the existence of variance. If $X_{k}$ are assumed to have more moments, one can get better bounds. For example, when $X_{k}$ are i.i.d. $\mbox{Ber}(p)$, we have the following theorem.
Hoeffding's inequality : Let $X_{1},\ldots ,X_{n}$ be i.i.d. $\mbox{Ber}(p)$. Then $$ \mathbf{P}\{|\bar{X}_{n}-p|\ge \delta\} \le 2e^{-n\delta^{2}/2}. $$

Italian vegetables are deep-fried in a crisp batter and served with a fresh dressing – try this as an informal starter that everyone can tuck into.
Fill a large bowl with water and add the lemon juice. Prepare the artichokes one at a time. Remove the tough outer leaves to reveal the pale inner heart. Open the heart and, using a teaspoon, scoop out the hairy choke. Peel the stem to remove the tough outside, leaving just the tender core. Chop the artichoke heart vertically in half, then cut the heart and stem into slices. Immediately immerse the artichoke in the lemon water to prevent it from turning brown.
For the batter, put the flour in a large mixing bowl and make a well in the middle. Pour the oil into the well, then mix it with the flour while slowly adding the warm water. Mix until the batter is smooth with the consistency of double cream.
Put a deep, heavy-based pan containing the sunflower oil on the heat until the oil is 180C, or alternatively use a deep-fat fryer. (CAUTION: hot oil can be dangerous. Do not leave unattended.) Preheat the oven to its lowest setting.
Drain the artichokes and pat dry using kitchen paper.
In a separate, clean glass bowl, whisk the egg white to soft peaks. Carefully fold it into the batter.
Fry the vegetables in batches, each type separately (cook the chard and sage leaves together). To do this, dip the vegetables into the batter and shake off any excess, then deep-fry them in the hot oil for 3–4 minutes, or until crisp and golden-brown all over. Drain on kitchen paper and keep warm in the oven while you cook the next batch.
Mix all the dressing ingredients together in a small bowl.
To serve, season the deep-fried vegetables with salt and pepper, drizzle the dressing over the top and serve with lemon wedges.

Version control systems are a category of software tools that helps record changes to files by keeping a track of modifications done to the code.
Use of Version Control System:
A repository: It can be thought as a database of changes. It contains all the edits and historical versions (snapshots) of the project.
Copy of Work (sometimes called as checkout): It is the personal copy of all the files in a project. You can edit to this copy, without affecting the work of others and you can finally commit your changes to a repository when you are done making your changes.
The git push command is used to upload local repository content to a remote repository. Pushing is how you transfer commits from your local repository to a remote repo. It's the counterpart to git fetch , but whereas fetching imports commits to local branches, pushing exports commits to remote branches
Through the course of these tutorials, we have got an account on GitHub and linked a local repository with a GitHub repository. Doing this gives us the freedom of using amazing GitHub features. While we have started to combine Git with GitHub, we will throw some light on how to copy someone else’s repository into our account (Forking in Git using Git Fork). The reason being simple and straightforward for this action, to make the changes or use the repository for our own purpose. In other words, in this tutorial, we will see the perspective of a person who wishes to contribute to a public repository (or a private permitted repository). This term or the process is called git forking about which this post is all about.
git clone is a Git command line utility which is used to target an existing repository and create a clone, or copy of the target repository. ... Cloning a local or remote repository. Cloning a bare repository. Using shallow options to partially clone repositories

Why does the second one work but not the first?
def id1 (x : ℕ) : ℕ := match x with | 0 := 0 | (n+1) := _match n + 1 --fails end def id2 (x : ℕ) : ℕ := match x with | 0 := 0 | (n+1) := by exact _match n + 1 --works end
(deleted)
Because the first one is intended to not work and the second one is not intended to work
I noticed this too, back here; I guess we're "supposed to" put x
to the right of the colon like Mario did in that thread.
Sometimes x
isn't an argument to the function however, it's something defined later.
the "official" solution is to just have an auxiliary function, or use induction
to construct the function. In lean 4, if my suggestion to sebastian worked, we will have an actual term mode notation for this using let

Recipes for Optional
published by Pradeep on April 03, 2018
Optional allows us to wrap a nullable object in it so we can make a method to return Optional instead of bare object. There is a possibility that below method can return null; so we need to explicitly do the null check on the returned object before using it.
Employee getEmployee(Integer id){
//return employee;
}
Check below modified method which returns Optional<Employee> and it communicates very well, saying that the result can be null.
Optional<Employee> getEmployee(Integer id){
// return optional employee
}
I will go through some recipes to handle Optional results, before that lets create an EmployeeService which returns Employee object.
class Employee{
private Integer id;
private String name;
private Integer age;
Employee(Integer id, String name, Integer age) {
this.id = id;
this.name = name;
this.age = age;
}
public Integer getId() { return id; }
public String getName() { return name; }
public Integer getAge() { return age; }
@Override
public String toString() {
return "Employee{ id=" + id +
", name='" + name + '\'' +
", age=" + age + '}';
}
}
public class EmployeeService {
Map<Integer, Employee> store = Map.of(1, new Employee(1, "Peter", 34),
2, new Employee(2, "John", 28),
3, new Employee(3, "Bill", 42));
Optional<Employee> getEmployee(Integer id){
return Optional.ofNullable(store.get(id));
}
}
Recipe 1: Check if result is present in the Optional using isPresent() and if it present then get the result using get() function.
EmployeeService es = new EmployeeService();
Optional<Employee> emp = es.getEmployee(2);
if(emp.isPresent()){
System.out.println(emp.get());
}
//Output: Employee{id=2, name='John', age=28}
Its not a good practice to use isPresent and get methods because this code is doing regular null check and then performing action on it. Instead follow the next recipes which will show you different ways to use Optional result. I used these methods to show available functions in the Optional class.
Recipe 2: Consume the result with out checking null. ifPresent() takes a consumer and it is executed only if the result is not null. We no need to explicitly check the null.
EmployeeService es = new EmployeeService();
es.getEmployee(2)
.ifPresent(System.out::println);
//Output: Employee{id=2, name='John', age=28}
Recipe 3: Consume and perform action if the result is present and if not present then perform empty action. ifPresentOrElse function takes two parameters, first parameter is consumer which will be executed if the result is present and second parameter is a runnable which will be executed when the result is null.
EmployeeService es = new EmployeeService();
//Employee id 5 is not available.
es.getEmployee(5)
.ifPresentOrElse(System.out::println,
() -> {System.out.println("No object present");});
//Output: No object present
Recipe 4: Perform filter before consuming the result. Filter function takes predicate and returns Optional. We can test the result before processing. Filter function returns empty Optional if predicate returns false.
EmployeeService es = new EmployeeService();
es.getEmployee(3)
.filter(emp -> emp.getAge() > 40)
.ifPresent(System.out::println);
//Output: Employee{ id=3, name='Bill', age=42}
Recipe 5: If result is present then perform action on it else perform action by creating new Optional. If getEmployee did not return Employee then we can create and return empty Employee. Other alternatives to this function is orElse(T other), orElseGet(Supplier<? extends T> supplier) both of these functions returns T instead of Optional<T>
EmployeeService es = new EmployeeService();
//Employee id 5 is not available.
es.getEmployee(5)
.or(() -> {return Optional.of(new Employee(0, "", 0));})
.ifPresent(System.out::println);
//Output: Employee{ id=0, name='', age=0}
Recipe 6: Throw exception if result is not present. orElseThrow takes supplier which should return throwable object.
EmployeeService es = new EmployeeService();
es.getEmployee(5).orElseThrow(() -> {
return new IllegalStateException("employee not available");
});
//Output: Exception in thread "main" java.lang.IllegalStateException: employee not available
Recipe 7: We can map the result to different type with map function. For example using map we can extract employee age from the employee object. The returned employee age from the map is wrapped in its own Optional. So make sure to unwrap it before using.
EmployeeService es = new EmployeeService();
es.getEmployee(2)
.map(Employee::getAge)
.ifPresent(System.out::println);
//Output: 28
Recipe 8: Alternative to map is flatMap function. Both of these functions returns Optional except in flatMap we need to explicitly map to Optional.
EmployeeService es = new EmployeeService();
es.getEmployee(2)
.flatMap(emp -> Optional.of(emp.getAge()))
.ifPresent(System.out::println);
//Output: 28


Under the Hood
There's a lot of changes in this new version of Bootstrap. Before we get into specific components, let's dig into some of the changes that aren't as obvious when you are looking to upgrade to this new version.
Dependencies
- jQuery
- Popper 2.0
- Dart Sass
Speaker Notes:
jQuery was at the heart of how bootstrap worked in the past. Bootstrap relied on jQuery for almost all of it's interactivity as well as its selector engine. All of that has now been re-written into pure javascript. That makes bootstrap load faster, because it uses less code.
For a lot of features, bootstrap relied on another library called Popper, so instead of using version 1 bootstrap 5 now uses version 2. You don't really need to worry about this unless you were also using popper to do some things yourself.
Bootstrap is built with Sass, and the older version used a processor called Libsass. That processor has now been deprecated, so bootstrap 5, like most modern projects now uses DartSass. It's faster and unless you're working with the sass version of bootstrap, you won't even notice.
Dropped Support
- Internet Explorer 10, 11
- Microsoft Edge < 16
- Firefox < 60
- Mac/iOS Safari < 12
- Chrome < 60
Speaker Notes:
Bootsrap is a modern framework and in order to evolve, older browsers had to be dropped. You can see that it doesn't support any versions of Internet Explorer and some versions of other browsers. If you need to support these, you should use an older version of Bootsrap.
Installation Changes
- No jQuery
- Popper
- RTL Versions
There are a couple of changes that you'll need to be aware of when installing. Obviously, you won't need to be installing a copy of jQuery with this new version, so if you're updating a site, you can safely remove jQuery unless you need it for your own site.
Since the version of Popper has been updated as well, you'll need to make sure you're loading version 2 if you're loading the file separately. Bootstrap does still add a bootstrap.bundle file with the new version of popper included.
The biggest change to your installation will be that there are now two different bootstrap installs. A regular bootstrap set of files and a whole other bootstrap RTL or Right To Left files. If you're using a language that uses a right to left orientation, then make sure you're loading a right to left version of Bootstrap.
JavaScript Changes
- NameSpaced
data-bs-toggle
notdata-toggle
- Plugins CSS Selector
let modal = new bootstrap.Modal('#yourModal')
Speaker Notes:
One of the things you'll notice when working with the scripts is that all of the data attributes now begin with data-bs
so that they don't conflict with other non-bootstrap library. This makes things safer, but it does require some updating in your older projects.
Another super useful feature is that plugins now take a CSS selector as the first argument. So to create an instance of an element a lot of times you just tell it the name of an element you want to use.

Intro
k-Loops is a system for live-coding. It allows to use Kotlin as a tool for artistic expression.
k-Loops is free and open source although it relies on Ableton Live which is not free.
Principles
Use Powerful Language
k-Loops is developed in Kotlin - very powerful jvm-based programming language.
In you live coding you can you whole power of this language and supporting tools: you can abstract and reuse common functionality, you can use automatic refactoring, and code suggestions.
k-Loops is the only live-coding system developed in Kotlin and if you like this language you should give it a try.
Ableton Live as a Synth Backend
k-Loops is a system that allow algorithmically control Ableton Live: you can play any midi tracks and you can easily discover and change any controls in ableton
Ableton Live is a great backend for live coding system: it has hundreds of instruments and effects that are very high quality.
Vast majority of live coding systems integrate with SuperCollider synth, that is pretty outdated comparing with Live.
Focus on Midi Control
k-Loops's focus is control of midi instruments: i.e. working with samples is deprioritized.
Big reason for this is that Ableton Live itself is a great tool to work with samples: once sample is imported in simpler, sampler or drum rack it's easily available for k-loops
Focus on midi control allowed to make it really right.
Develop Right Abstractions
k-Loops is based on very few flexible and powerful low-level abstractions,
such as triggers
, playAsync
, silence
.
These abstraction are used as bricks to build more convinient high-level abstractions, such as
patterns
and sequences
Both types of abstractions are available to use you can use high-level abstraction to express very complex idea succinctly or you can use low-level abstraction to program music exactly how you want.
Examples
Synth-Pop
val runBackgroundTasks = startBackgroundTasks()
loop("main loop") {
"c2 a2 c2 a2 e2 f2 c3 c3".toSeq().forEach { n ->
if (n == "c3") triggerEvent("c3")
else triggerEvent("c2")
sequencer(_8th) {
"k . sn . k k sn .".play(track("drums"), 1.0)
"c3 g3 e3".play(track("keys 1"), 0.5)
"$n . $n .".play(track("bass"), 1.0)
}
}
}
loop("hi hat") {
silence(_8th)
track("drums").play("ch", _4th, 0.5)
triggerEvent("hat")
}
runWhenEvent("additional drums", listOf("hat")) {
sequencer(_16th) {
"co rm".play(track("drums"), 1.0)
}
}
runWhenEvent("pads 1", listOf("c2")) {
sequencer(_4th) {
"e4 . . f4 ".play(track("pad"), velocity = 0.3, length = _q.dot())
}
}
runWhenEvent("pads 2", listOf("c3")) {
track("pad").playAsync("c4", _half, 0.1)
}
Polyrithmic Techno
val runBackgroundTasks = startBackgroundTasks()
loop("techno") {
sequencer(_16th) {
"k . co . cl . co co".play(track("drums"), velocity = 0.5)
val bass2Length = listOf(2, 5, 7, 1, 3).look() o 64
val velocity = listOf(0.2, 0.0, 0.1, 0.1).look()
"a1 . . g1".play(track("bass"), velocity = velocity, length = bass2Length)
val cutoff = triag(from = 0.01, to = 0.25, period = 12, t1 = 8)
val mod = sine(from = 0.6, to = 0.7, period = 4, jitter = 0.1)
val delay = trapezoid(from = 0.0, to = 1.0, period = 16 * 32, t1 = 7 * 16, t2 = 20 * 16)
val midGain = rect(from = 0.5, to = 0.60, period = 8, phase = 0.5)
master().device("master").parameter("mid gain").setValue(midGain)
track("bass").parameter("mod").setValue(mod)
track("bass").parameter("cutoff").setValue(cutoff)
track("bass").sends("Delay").setValue(delay)
}
}
loop("techno2") {
sequencer(_16th) {
setLoopVelocity(trapezoid(period = 16 * 16, t1 = 4 * 16))
"k . . sn k . .".play(track("drums"), velocity = 0.7)
". . rd ch . .".play(track("drums"), velocity = 0.1, length = _32nd)
"clave clave . . clave .".play(track("drums"), velocity = 0.5)
}
}
loop("techno3") {
sequencer(_16th) {
setLoopVelocity(trapezoid(period = 16 * 16, t1 = 4 * 16, phase = 0.5))
"mid . rm mid . .".play(track("drums"), velocity = 0.5)
". . sn sn . .".play(track("drums"), velocity = 0.5)
}
}

 Here it is stuffed with a fruity filling and slow-roasted. Serve with matchstick fries and freshly cooked green vegetables.
To make the stuffing, melt the butter and oil in a large non-stick frying pan over a medium heat. Gently fry the shallot and garlic for five minutes, stirring regularly until softened, but not coloured.
Remove the pan from the heat and stir in the apple, peaches, sultanas, stem ginger, breadcrumbs, ground ginger, herbs, lemon zest and juice. Season with salt and plenty pepper and mix well. Add the stem ginger syrup and mix again until the stuffing comes together. Allow to cool.
Place one of the fillets between two sheets of cling film and bash with a rolling pin until around 1cm/½in thick. Set aside and repeat with the other.
Place a large sheet of cling film on a board and lay the bacon in slightly overlapping lengths on top; making a rectangle roughly 32x28cm/13x11in. If some of the rashers are a little short, stretch with the back of a knife.
Place one of the fillets in the centre of the bacon and spread with the stuffing. Cover with the other fillet to sandwich the stuffing. Bring the bacon up over the top of the venison to enclose it completely, using the cling film to help you. Wrap tightly in more cling film and chill in the fridge overnight or at least 1 hour.
Preheat the oven to 200C/180C Fan/Gas 6. Unwrap the venison and place on a lightly greased baking tray, with the ends of the bacon underneath. Roast for 30 minutes, or until the bacon is crisp and the venison is just cooked.
Remove from the oven and transfer to a board or warmed serving platter. Cover with foil and leave to rest.
Carve the venison into slices and divide between six warmed dinner plates. Spoon a little of the resting juices over the venison.
