Release date: 2000-05-08
This release contains improvements in many areas, demonstrating the continued growth of PostgreSQL. There are more improvements and fixes in 7.0 than in any previous release. The developers have confidence that this is the best release yet; we do our best to put out only solid releases, and this one is no exception.
Major changes in this release:
Foreign keys are now implemented, with the exception of PARTIAL MATCH foreign keys. Many users have been asking for this feature, and we are pleased to offer it.
Continuing on work started a year ago, the optimizer has been improved, allowing better query plan selection and faster performance with less memory usage.
psql, our interactive terminal monitor, has been updated with a variety of new features. See the psql manual page for details.
SQL92 join syntax is now supported, though only as INNER JOIN for this release. JOIN, NATURAL JOIN, JOIN/USING, and JOIN/ON are available, as are column correlation names.
A dump/restore using pg_dump is required for those wishing to migrate data from any previous release of PostgreSQL. For those upgrading from 6.5.*, you can instead use pg_upgrade to upgrade to this release; however, a full dump/reload installation is always the most robust method for upgrades.
Interface and compatibility issues to consider for the new release include:
The date/time types datetime and timespan have been superseded by the SQL92-defined types timestamp and interval. Although there has been some effort to ease the transition by allowing PostgreSQL to recognize the deprecated type names and translate them to the new type names, this mechanism cannot be completely transparent to your existing application.
The optimizer has been substantially improved in the area of query cost estimation. In some cases, this will result in decreased query times as the optimizer makes a better choice for the preferred plan. However, in a small number of cases, usually involving pathological distributions of data, your query times might go up. If you are dealing with large amounts of data, you might want to check your queries to verify performance.
The JDBC and ODBC interfaces have been upgraded and extended.
The string function CHAR_LENGTH
is now a
native function. Previous versions translated this into a call
to LENGTH
, which could result in
ambiguity with other types implementing
LENGTH
such as the geometric types.

After finally settling down into a semi routine, Dylan sleeping through the night and mum and dad finally finding some time to recoup - believe you me, you never know how good a full nights sleep is until you go without for a number of months! After donning his specially tailored church suit (all the way from the spanish relies), we arrived early so we could feed him before mass. Unfortunately, it clashes with one of his feeds - however, the 10:30 mass we have been told is child friendly, and so we are looking forward to making lots of noise and causing a general disturbance. Boyz in da hood. Dylan striking a catalog pose The day went really well. We met Father Kevin after mass (it had been a LONG time since mum and dad had entered the hallowed halls, and it was actually a not so bad experience - fully attended, with altar 'girls' and lots of singing and involvement) and went to the social club and were introduced to members of the local community. We took Dylan to see Lolo and Lola again, as well as his aunts, uncles and cousins. This gave mum and dad the opportunity to sneak off for some quiet time in Christchurch harbour. Errr, mum. What are you doing on my swing?
It had only been a few weeks since lolo and lola had seen Dylan, but he grows so much and so quickly. In May, he reached 15lb, and is above average for his corrected age - fantastic! So, as i was saying..... As you can see, he looks quite at home chatting to lolo - at last, someone who speaks his language. In May, mum and dad got me some new accessories for my pushchair - a foot muff. It was interesting watching dad try and put it together, so it was left to mum to figure it out......I don't know how I managed without it, and am thrilled at being able to lose countless socks and other items in the further reaches of the foot muff ... Let me see what i have down here today..... I have already established my position on the comfy sofas, although I need some time to grow into these seats.... Hello.. I have some new toys delivered, although i am not really sure about some of them. The converted wash basket (apparantly, a la mode in the creches of Paris) was a bit of a let down, but the parachute trainer was fun, although I don't think I am ready for static lines yet... How do you steer this thing? where the chute? Sometimes Susie comes around with Ralph and Daphe and I can't help but stare... After so much activity, I like to end the day with a short siesta... Zzzzzz

Welcome
This is a work in progress split-flap display. Each module can flip between 40 unique characters: letters, numbers, and a few symbols. Multiple modules fit perfectly alongside each other to build bigger displays.
The primary design goal was to make something that's possible to fabricate at home in small or single quantities and can be customized and built by an intermediate hobbyist at a reasonable price. This meant using widely available materials and avoiding any tooling with a high upfront cost.
Following that philosophy, the design uses store-bought vinyl stickers for the letters, is driven by an ubiquitous and cheap 28BYJ-48 stepper motor, and uses common PVC ID badge cards cut to shape for the flaps (though custom die-cut flaps are also available). Even the enclosure, spool, and gears, which are all made from laser-cut MDF, can be easily ordered online.
This design is currently nearly stable. The source code in the git repo has been used to produce several working prototypes, and the v0.5 design is stable enough to have fairly comprehensive Ordering Instructions and an Assembly Guide. Of course, as this is an open source side-project, you may still come across minor issues or missing documentation.
Open source, up to date
All of the designs are open source. The 3d model is built using OpenSCAD, the driver electronics board is designed in KiCad, and the driver firmware is written using Arduino.
Most of the supporting materials, like the schematic, bill of materials, PCB gerbers, and even the interactive 3D rendering seen above are generated automatically as the design changes, using Github Actions. This way you can always see the latest designs, even without having to check out the git repo or install any software yourself.
I'd love to hear your thoughts and questions about this project, and happy to incorporate any feedback you might have into these designs! Please feel free (and encouraged) to open GitHub issues, email me directly, reach out on Twitter, and get involved in the open source development and let's keep chatting and building together!

Moody’s wants New York to raise tolls on Thruway
ALBANY, N.Y. (AP) - A credit ratings agency says the lack of a plan for toll increases on the New York State Thruway and on the new Gov. Mario M. Cuomo Bridge in the Hudson Valley could endanger the road’s bond rating and borrowing costs.
The Rochester Democrat and Chronicle reports that Moody’s Investors Service is suggesting that tolls will have to go up by 2022.
A moratorium on toll increases on the thruway and the bridge is set to expire at the end of 2020. The Thruway Authority could need an additional $53 million to cover its costs by 2022.
Democratic Gov. Andrew Cuomo has used $2 billion in settlements from Wall Street firms to bail out the authority.
The authority hopes to save $300 million on bridge debt through refinancing.

Fashion Fredericks! Five Of Stiga's Most Swagged Out Looks
by SL SocialDuring his playing days, South African football great Stanton Fredericks was known to be one of the most skilful players of his generation. Away from the pitch, you’d find "Stiga" to be quite the fashionista. Check it out!
The former Kaizer Chiefs fan favourite knew how to turn it on during matches, and whether it be shibobos or tsamayas, Stiga knew every trick in the book and brought the aesthetic element to the game.

With his playing days behind him, Fredericks now offers his professional opinion as a pundit, and does so stylishly.
The ex-Bafana Bafana star always looks immaculate on-screen, and often wears buttoned up shirts with style and finesse. It also appears that Stiga likes his shades, and often wears them accompanied by a fresh haircut.
To see some of Stiga's drip, scroll through the gallery above!
Do you think Fredericks is the most stylish SA football legend today?

Publication type: Statistical First Release
Publication data: Prerelease access data
Region: England
Release date: 21 March 2013
Coverage status: Final
Publication status: Published
This statistical release provides national projections for the number of pupils in schools by type of school and age group. Findings presented here update those published in July 2012 (OSR15/2012) using the latest mid-2011 based interim sub-national population projections from the Office for National Statistics (ONS). The mid-2011 population projections are the first to incorporate findings from the 2011 UK Census.
This is an official statistics publication. The statistics are presented as the latest available findings and have been released to help planning, to study trends and to inform a variety of programmes and initiatives.
This release presents the Department for Education’s main national-level pupil projections. The statistical release school capacity: academic year 2011 to 2012 was published on 1 March 2013 (SFR01/2013) and included local authorities’ own forecasts of future pupil numbers, based on local-level information, such as inter-authority migration of pupils.
The national pupil projections presented in the current release are produced within the Department for Education (the Department), at a national level only. They are based on the latest national population projections from ONS and cover a longer time period (up to 2021) than the school capacity release (SFR01/2013). Differences in the methodologies used by individual local authorities for pupil number forecasts mean that the aggregated totals in school capacity academic year 2011 to 2012 will differ from the national-level projections presented here.
This statistical release does not include tables or figures presented in previous releases concerning the effect of varying migration assumptions on pupil numbers. This is because the latest ONS interim population projections did not include the variant migration scenarios which are required to derive such tables and figures. ONS have indicated plans to reinstate the publication of migration variants with their 2012-based population projections in October/November 2013, following which it is expected that alternative migration scenarios will again be included in future pupil projections statistical releases.

The stationary heat equation is a partial differential equation that describes the variation in temperature in a material in stationary conditions. In two dimension, it looks like : $$\frac{\partial ^2 T}{\partial x^2} + \frac{\partial ^2 T}{\partial y^2} = \frac{1}{k} q(x,y)$$
where :
\(k\) is the thermal conductivity (\(W.m^{-1}.K^{-1}\)) of the material studied ;
\(q\) is the heat flux density (\(W.m^{-2}\)) of the sources.
During S6 at ENSEIRB-MATMECA, I completed 6 two-week numerical analysis projects, using Python, in teams of 5 or 6 students. The numerical solution of the stationary heat equation was one of the most interesting in my opinion, so I decided to display it here, to showcase my abilities in Python and numerical analysis.
At the time, my team did a quite good job considering the small amount of time we had. But I was not completely satisfied, so during summer 2015, I made a critical examination of our code, immerse myself into the mathematics behind it, and rewrote most of it. I also developped a simple GUI. This page presents this process and the final result, which is downloadable from this github repository.
A possible approch to numerical solutions of partial differential equation is the finite-difference methods.
Basically, it is a discretization method where finite differences are used to approximate the derivatives.
Assuming the temperature function is properly-behaved, we can write thanks to Taylor theorem :
$$T(x+h,y) = T(x,y) + h \frac{\partial T}{\partial x}(x,y) + \frac{h^2}{2} \frac{\partial^2 T}{\partial x^2}(x,y) + \frac{h^3}{6} \frac{\partial^3 T}{\partial x^3}(x,y) + \frac{h^4}{24} \frac{\partial^4 T}{\partial x^4}(\eta,y)$$
$$T(x-h,y) = T(x,y) - h \frac{\partial T}{\partial x}(x,y) + \frac{h^2}{2} \frac{\partial^2 T}{\partial x^2}(x,y) - \frac{h^3}{6} \frac{\partial^3 T}{\partial x^3}(x,y) + \frac{h^4}{24} \frac{\partial^4 T}{\partial x^4}(\zeta,y)$$
where \(\eta \in [x, x+h]\) and \(\zeta \in [x-h, x]\), then by adding both equations :
$$\frac{\partial ^2 T}{\partial x^2}(x,y) = \frac{T(x+h, y) - 2T(x,y) + T(x-h, y)}{h^2} + \frac{h^2}{24} \Big (\frac{\partial^4 T}{\partial x^4}(\eta,y) + \frac{\partial^4 T}{\partial x^4}(\zeta,y)\Big)$$
Finally, by doing the same thing on the other axis, and disregarding the fourth and upper order terms when \(h\) is small enough, we can rewrite the stationnary heat equation as :
$$ \frac{T(x+h, y) + T(x, y+h) - 4T(x,y) + T(x-h, y) + T(x-h, y)}{h^2} = \frac{1}{k} q(x,y) $$
Now let us assume we want to solve the 2-D stationnary heat equation on a surface \( [a,b] \times [a,b] \).
To solve it numerically, we discretize the space in a \(n\times n \) matrix of regularly spaced points.
As a consequence, the heat flux density field is also discretized, and represented by a \(n\times n \) matrix Q, such as \(\forall (i,j), \ q_{i,j} = q(i*h,j*h)\).
Finally, an approximation of the temperature field in all the discrete points, in the form of a \(n\times n \) matrix T, such as \(\forall (i,j), \ t_{i,j} \simeq T(i*h,j*h)\), is obtained by considering the set of \((n-2)*(n-2)\) equations :
$$ \forall (i,j) \in [[1,n-2]]\times[[1,m-2]], \ \frac{t_{i+1,j} + t_{i,j+1} + 4_{i,j} + t_{i-1,j} + t_{i,j-1}}{h^2} = \frac{1}{k} q_{i,j} $$
and the \(4(n-1)\) boundary conditions.
Let us note \(matToVect()\) the operator transforming a \(n\times n\) matrix into a \(n*n\) column vector whose \(i\)-th coefficient is the \((i/n, i\%n)\) coefficient of the matrix, and \(vectToMat()\) the reverse operator.
By choosing null boundary conditions, this system of \(n^2\) linear equations can be put in the form of a matrix system : \(Ax= matToVect(Q)\) where
$$A=\begin{bmatrix} B & C \\ C & B &\ddots \\ &\ddots & \ddots & C \\ & & C & B \end{bmatrix}
\
\text{with }
B= \begin{bmatrix} -4 & 1 \\ 1 & -4 &\ddots \\ &\ddots & \ddots & 1 \\ & & 1 & -4 \end{bmatrix}
\text{ , }
C= I_n
\text{ , } T = vectToMat(x) $$
The matrix \(A\) described above has an interesting characteristic : \(-A\) is symmetric and positive definite. Now, if a matrix \(M\) is symmetric positive definite, it has a decomposition called Cholesky factorization of the form \(M = LL^*\) where \(L\) is a lower triangular matrix and \(L^*\) is its transpose. This decomposition, which can be performed in \(\Theta(n^3)\) for a \(n\times n\) matrix, is very useful, as it allows to solve very efficiently and with great numerical stability \(Ax = col(Q)\) by solving two triangular linear systems (\(Ly=col(Q)\) then \(-L^*x=y\)).
There are several algorithm that perform this factorization, but one of the fastest is the Cholesky–Crout algorithm, which computes coefficients of \(L\) one by one, starting from the upper left corner, and proceeding column by column, thanks to the following formulas :
$$ L_{j,j} = \sqrt{A_{j,j} - \sum_{k=0}^{j-1} L^2_{j,k}}$$
$$ L_{i,j} = \frac{1}{L_{j,j}} \Big (A_{i,j} - \sum_{k=0}^{j-1} L_{i,k} L_{j,k} \Big) \ \text{for } i > j$$
The first implementation of this algorithm made by my team was pretty slow, and as a result, we could only use it on small matrices, resulting in poor approximations. I first tried to optimize it by concatenating some loops, and removing intermediate variables and functions. The resulting function, that you can found under the name oldCompleteCholesky
, was slightly faster, but still very slow for a \(\Theta(n^3)\) ...
After some research, I became aware of this existence of a Cholesky factorization function in Numpy, a library I had been using for matrix computations. I compared its execution time with my custom function and the result puzzled me : my function was so slow, that Numpy's seemed to be running in constant time in comparison.
I explored another lead, which was using the incomplete Cholesky factorization, which gives a good approximation for sparse matrices like A (which density is only a few percents, and decreases with its size). As you can see, it was faster, and gave a very close approximation, but it still was not as fast as Numpy's function, which gave exact results !
I read Numpy's function source code and found out the origin of my problem. Numpy's Python Cholesky function is just a kind of wrapper for a C function, which itself make calls to the LAPACK, a Fortran library developped by american academics.
I then understood that I was not using Python in the "right" way, performance wise. Python is developped in C, and performing Python loops over the matrices coefficient is far slower than using standard functions which perform C loops and give the same result !
So, in completeCholesky
I replaced every loop I could by matrix multiplications, and reached half the speed of Numpy's function !
I developped the final solving function using Numpy's functions which were (of course) still faster. The file heatEquation.py contains the function heatEquationMatrix
which produces the matrix A described above, the functions matToVect
and vectToMat
. The function solveHeatEquation
uses them, as well as Numpy's cholesky
and solve_triangular
, to solve the stationary heat equation.
Finally, I used Python standard GUI package, Tkinter, to wrap the solving function in a simple interface. It is very simple to use : choose the size of the discretized plane you want to work on, then draw the heat flux density by clicking on the grid and click on the solve button.

HTML5- is a markup language used for structuring and presenting content on the World Wide Web. It is the fifth and current version of the HTML standard
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language. Although most often used to set the visual style of web pages and user interfaces written in HTML and XHTML, the language can be applied to any XML document, including plain XML, SVG and XUL, and is applicable to rendering in speech, or on other media.
JavaScript is a high-level, dynamic, untyped, and interpreted programming language. It has been standardized in the ECMAScript language specification. Alongside HTML and CSS, JavaScript is one of the three core technologies of World Wide Web content production; the majority of websites employ it, and all modern Web browsers support it without the need for plug-ins
Meteor, or MeteorJS, is a free and open-source JavaScript web framework[3] written using Node.js. Meteor allows for rapid prototyping and produces cross-platform (Android, iOS, Web) code. It integrates with MongoDB and uses the Distributed Data Protocol and a publish–subscribe pattern to automatically propagate data changes to clients without requiring the developer to write any synchronization code. On the client, Meteor depends on jQuery and can be used with any JavaScript UI widget library.

I’ll be a blogger (again)
After reading this post, I was motivated to start blogging about development/design. I’ve had several blogs in the past, so I’m not stranger to this world. However, I don’t consider myself an authority on development or design, so I’ve been reluctant. The plan is to keep this going throughout the year and, ideally, make it into something useful.
I’ll know how to use JS promises
I’ve never used a promise. Not even once. I’d be ashamed, but I’m honestly not sure how embarrassing this should be.
I’ll have a collection of UI/react components
I envy great UI designers. I made and remade dozens of UI components last year. I plan on doing that much less as time goes on. I’m still learning React, so these components may or may not be of the React variety, but I’m optimistic.
I’ll have written a JS library
I won’t feel legit until my Github page boasts at least one original library. I have no idea what it will be, but I have a whole year to figure that out.
I’ll be a professional
I’ve done paid internships in the past, but I want to do this for real. To me, that doesn’t necessarily mean being hired at a company. Ideally, I’ll be working as a freelancer, which brings me to my final point.
 I find that fact both intimidating and exciting. I also have a long-time project that I’ll be finishing up next year and hopefully turning into a business.


Background
In the early 1990s Frank Cringle wrote an exerciser for the Z80 and released it under the GNU General Public License. The purpose of the exerciser was to test the operations of Z80 emulators against the results obtained from a physical Z80 CPU, and to document the results.
I was in need of a way to test my 8080 emulator, so I have modified Frank's work to provide a similar facility for the 8080 CPU. Details of the changes I made, and Frank's original documentation, can be found in the source file (link below).
The exerciser doesn't work in the way you would probably expect: perform a single CPU instruction and immediately check the resulting processor state. Instead it programatically selects, and executes with varying arguments, a series of associated opcodes (all 8 bit ALU operations for example) and after each operation it merges the new CPU state (registers and flag values) into a running CRC value.
After each individual group of tests you therefore end up with a single CRC value that represents the amalgamated results of every operation that was executed as part of that test. If you run the same test on a physical CPU as well as an emulator, and the generated CRC value from each source is identical, then you can safely assume that the emulator is working in exactly the same way as the hardware.
There are two downsides to this technique -
- You only get a Pass/Fail response. There is no indication as to which operation failed.
- You have to have access to the results of the same tests run on a physical CPU, to obtain the baseline results.
There's nothing much I can do about the first downside, that's up to the emulator writer and a lot of tea (or coffee). The second downside is what this page hopes to address.
Basic Exerciser
The basic exerciser has no pre-defined CRC result values. For each test it expects a 32-bit CRC of 0 and, as a different result will always be obtained, it reports the test as failing. However, the error message also includes the expected CRC, and that is what we are interested in here.
I would appreciate it if anyone who has a CP/M 2.2 system running on an 8080/8085 processer would run the exerciser and let me know the reported values along with a description of the 8080/8085 CPU used. I can then add the expected CRC values to an updated version of the exerciser, allowing emulator writers to have a simple to use test for the accuracy of their emulation.
Basic Exerciser Files
All files are provided in three different formats
- mac - source code for the Microsoft M80 assembler.
- com - the source assembled into a CP/M com file.
- hex - the source assembled into a CP/M (Intel format) hex file.
- These files contain a modified version, for the 8080/8085, of Frank Cringles original preliminary test file. The purpose of this additional test, to be run before the main exerciser (both 8080 and 8085 versions), is just to test that the emulator is performing basic operations correctly (jmp, call, mvi etc).
- These files contain the basic exerciser for a CP/M system using an 8080 CPU.
- These files contain the basic exerciser for a CP/M system using an 8085 CPU.

Grateful thanks to those listed above for providing results and advice.
The download links in the above table lead to copies of the original exerciser files that have had the appropriate CRC values inserted in them. When you run the exerciser it will then report "OK" for tests that result in the correct CRC value. It makes it a lot easier to spot any errors!
For more information about Alexander Demins 8080 CPU collection see his blog.
More Results Needed
Results for other CPU hardware versions are still needed, so if you have a system with an 8080 or 8085 CPU the please consider running the basic emulator and forwarding the results to me; it really would be appreciated. Apart from the help it would provide to emulator writers it would be nice, even at this late stage, to document some of the differences between the various implementations of the 8080 and 8085 CPUs.

FEAR AND LOATHING IN LAS VEGAS
Reviewed by Harvey Karten, Ph.D. Universal Films Director: Terry Gilliam Writer: Terry Gilliam, Tony Grisoni, Tod Davies, Alex Cox, novel by Hunter S. Thompson Cast: Johnny Depp, Benicio Del Toro, Ellen Barkin, Gary Busey, Cameron Diaz
No other film this year has divided critics and general audience alike as much as "Fear and Loathing in Las Vegas." Negative criticism including comments like "if you can possibly avoid seeing this movie, do," and "does not translate well from book to screen" and "just one damn event after another." Positive input included comments like "at least as hilarious as the book," "an absolute hoot," and "Johnny Depp and Benicio del Toro play off against each other better than Don Quixote and Sancho Panza."
The nays have it. Hunter S. Thompson's classic 1971 book about a hip journey into the square American dream may have been required reading on many college campuses, holding for itself the status that J.D. Salinger enjoyed with "Catcher in the Rye." The screen version is something else, principally since the chief attribute of the book--the way the narrator keeps you reading relentlessly ahead by his dense verbiage--comes across visually in a fragmented course. The movie is really just one scene after other, giving the impression that each tableau could form the basis of a separate narrative, but the images just do not gel as segments of a 128-minute work. Johnny Depp's off-the-wall performance is a one-note business. Dangling a cigarette in a holder as though he were developing an antenna to communicate to the world, he is so unable to speak in a coherent voice that the narration by another actor is essential. Given his body's penchant to be an entire pharmaceutical company, his use of tobacco comes across as overkill. Benicio Del Toro does a more complex job as the overweight Samoan attorney (he is a Chicano in the book), repeating the injunction "speaking as your attorney I must advise you..."
"Fear and Loathing in Las Vegas" is about a journalist, Raoul Duke, who in the late sixties is disappointed in the way America is heading and disgusted with the leadership of President Nixon. He defensively develops an affinity for drugs, which he considers "hip." His are the people who will bring about a greening of America by trashing the absurd squareness of the silent majority. Heading with his attorney, Dr. Gonzo (Benicio del Toro), to cover a motorbike race for Sports Illustrated, he decides that the best journalistic truth comes from fiction--from a disposition to hype what the reporter finds in order to highlight its meaning. As the two men drive from L.A. to Las Vegas, the home of the American Dream with its icon, the impossibly square Debbie Reynolds, they proceed to trash their hotel rooms, skip out without paying their bills, and generally subvert the culture of the square by living close to the edge.
Thanks to special effects technology, director Terry Gilliam (of Monty Python fame) is able to illustrate much of the hallucinogenic images conjured up by the disillusioned Raoul.   In yet another scene, one involving a convention of district attorneys discussing the subject of dangerous drugs, director Gilliam makes good use of Michael Jeter, who describes the evils of the weed without believing a word he says--as though he were telling his audience of law enforcement officials that the convention is a farce and that they're all there to play the roulette wheel, not to insure that the nation goes sober.
Two scenes are almost an embarrassment: one in which Dr. Gonzo introduces Raoul to Lucy, a jail-bait pickup played by Christina Ricci who has latched on to the much older man; and another featuring an almost unrecognizable Ellen Barkin as a waitress in a greasy spoon who realizes too late that she should not have stood up to these two psychedelic guys, one of whom threatens her life with a huge hunting knife.
Hunter S. Thompson's book, which is classified as non- fiction, is a frenzied description of his own trip to the American Dream, the author himself later becoming as muddled as his Raoul and who, like J.D. Salinger, retreated from the world to a remote village. Terry Gilliam, who, like the writer enjoyed his own peak of success but later dwindled and faded, has been unable to realize Thompson's point of view--to depict the world of hip America just before the great disllusionment. You leave the theater wondering why the most intelligent guy in Danny Boyle's movie "Trainspotting" tells us "imagine your best orgasm and then multiply it by one thousand" to describe the pleasures of illegal drugs. What is the great pleasure attached to watching the hotel floor shimmy and shake, your best friend turn into a Mephistophelean buffalo, and tourists in a cocktail party turning into lizards?

PI A film review by Matt Williams
RATING: * out of * * * *
Darren Aronofsky makes his directoral debut with this uneven paranoid thriller, Pi. It's filled with plenty of new concepts and ideas, but also with a healthy dose of pretension.
Max Cohen (Sean Gullette) is a brilliant mathematician on the borders of madness. He theorizes that since mathematics is the language of nature, everything can be comprehended purely and completely on the basis of numbers. The key to understanding is to find the patterns that underlie everything.
To confirm his theories, Max builds an archaic/state-of-the-art computer system to crunch numbers on the stock market. Once he discovers the key, he should be able to predict stock prices at will. But things don't work out as smoothly as he plans.
He keeps running into a peculiar bug, one which may have caused his mentor, Sol (Mark Margolis), to give up mathematics completely.
Aronofsky has talent. It's not every writer-director who could combine topics as diverse as Fibbonacci numbers, phrenology, Kabalah, Chaos Theory, numerology and Go into a single coherent (if not terribly accurate) film. Plus, he is able to go a long way on a low budget, producing some striking cinematography as he goes.
However, despite all of that, Pi fails as a film. There are two stories in the film (Max and his theories, and Max and his descent into madness), but neither one is satisfactory. The former is implausible, strains credibility, and is ultimately pointless. The latter is more interesting at times, but while it certainly gets disturbing at times, it's all style and little substance.
Part of the problem rests with Sean Gullette. As the lead character, he is rather bland (particularly as a "mad mathematician"). None of the actors in the film give stellar performances, but in an introspective storyline, Gullette's performance is key, and not quite up to par.
Pi is stylistically interesting, but empty overall. There's a thin line between genius and incomprehensible madness. The film falls solidly in the latter camp.

Preparation time
less than 30 mins
Cooking time
10 to 30 mins
Serves
Serves 2
A steak dinner for two made special with a simple, classy dressing.
Marinade the steaks in the oil, black and pink peppercorns and the fennel seeds for up to half an hour. Preheat a griddle pan. Rub the steaks with oil and season with salt and pepper.
When the griddle is very hot, cook the steaks on both sides for 2-3 minutes, then set aside and keep warm. Let them rest for the same amount of time as they were cooked.
For the béarnaise sauce, place the vinegar, shallot, black peppercorns and stalks of the tarragon in a small saucepan with 2 tablespoons water and cook until it has reduced in volume by half. Strain and transfer to a food processor.
Add the egg yolks and start to blend. With the motor running, gradually add the melted butter until you have a smooth sauce. Finish with the chopped tarragon leaves, salt and pepper.
To make the chips, fill a deep-fat fryer or a large, deep, heavy-bottomed pan half full with vegetable oil. Heat the oil to 180C (use a probe thermometer to check the temperature if you're not using a deep-fat fryer). (CAUTION: Hot oil can be dangerous. Don't leave unattended.)
Pat the cut potato dry using a tea towel or kitchen paper. Carefully add the chips to the oil and deep-fry until cooked through (about 3 minutes). Set aside to drain on kitchen paper.
To serve, cut the steaks into slices and serve with the fries and sauce.


This is a simple example of how to use CSS transformation and animations to get interesting-looking behavior.
The three rings are constructed using a simple JavaScript function that creates elements and assigns them a transform that describes their position in the ring. CSS animations are then used to rotate each ring, and to spin the containing element around too.
Note that you can still select the numbers on the ring; everything remains clickable.

@meatspoon no gas fees are ridiculous and unacceptable.
fees are one thing, but the global network fee on eth gets out of hand when there’s congestion.
tolken27-Jun-19 03:45 PM
Imagine paying $5 every time you want to interact with a dapp. Let’s say it takes on average 3 interactions to use that dapp, and all you want to do with the dapp is check your balance and make a payment. Yeah, that’s what eth has been like.

Hi! Is this a proper channel for asking (elementary) questions?
I'm stuck trying to prove the following trivial statement:
def func_as_set {α β} (f : α → β) : set (α × β) := { x | x.2 = f(x.1) } example {α β} (a : α) (f : α → β) : (a, f a) ∈ func_as_set f := sorry
Refl and Simp tactics don't seem to work, unfortunately
Did you try rfl
?
I don't think so. I will do it now.
refl
works for any reflexive relation, and I guess the elaborator looks for a proof that ∈
is reflexive. rfl
is only for equality.
omg that worked. Thanks for the elaboration too. Very useful to know!!
PS
Hi! Is this a proper channel for asking (elementary) questions?
Here is fine, although most of the elementary questions get asked in #new members . There are no hard and fast rules though.
Cool, thanks
In that case, I have another trivial follow up ;-) How does one go from a hypothesis in this form
x ∈{ y | P y }
to
P x
?
Again isn't that rfl
?
rw set.mem_set_of_eq
also works. That lemma does not have a good name.
but you can't use that when it's a hypothesis, right?
rw _ at h
right - trying now
Are you in tactic mode or term mode?
if h
is your hypothesis.
tactic mode
you can just change it
or pretend that it's already in that form
depending on what you're trying to do
You could do change P x at h
as well
oooh, that's useful
thanks folks!
Because the two terms are definitionally equal you might not even need to change it
@Kevin Buzzard my proposition is an equality in this case. i need it for a rewrite. doesnt seem to work without an explicit change
with the change, it does! :-)
Post some working code?
But yes, rw
needs things to be unravelled explicitly.

Safe Numerics |
This library should compile and run correctly on any conforming C++14 compiler.
The Safe Numerics library is implemented in terms of some more fundamental software components described here. It is not necessary to know about these components to use the library. This information has been included to help those who want to understand how the library works so they can extend it, correct bugs in it, or understand its limitations. These components are also interesting in their own right. For all these reasons, they are documented here. In general terms, the library works in the following manner:
All unary/binary expressions where one of the operands is a
"safe" type are overloaded. These overloads are declared and defined
in the header file "safe_integer.hpp". SFINAE - "Substitution Failure
Is Not An Error" and std::enable_if
are key features of
C++ used to define these overloads in a correct manner.
Each overloaded operation implements the following:
Retrieve range of values for each operand of type T from
std::numeric_limits<T>::min()
and
std::numeric_limits<T>::max()
.
Given the ranges of the operands, determine the range of
the result of the operation using interval arithmetic. This is
implemented in the "interval.hpp" header file using the
constexpr
facility of C++14.
If the range of the result type includes the range of the result of the operation, no run time checking of the result is necessary. So the operation reduces to the original built-in C/C++ operation.
Otherwise, the operation is implemented as a "checked integer operation" at run time. This operation returns a variant which will contain either a correct result or an exception enum indicating why a correct result could not be obtained. The variant object is implemented in the header file "checked_result.hpp" and the checked operations are implemented in "checked.hpp".
If a valid result has been obtained, it is passed to the caller.
Otherwise, an exception is invoked.

Deadline looming for budding writers to take part in the national Chorley & District Writers’ Circle short story competition
by Nicola AdamThere is just a few weeks left to enter Chorley & District Writers’ Circle annual, national short story competition.
Prizes for the competition total £210 – the highest ever prize fund.
This year the theme is open to a multitude of interpretations of ‘on the edge’.
Maximum word count is 2,500 and the closing date is 15 December 2019 at midnight.
The shortlist will be judged by the competition’s sponsors: editorial consultancy Fiction Feedback www.fictionfeedback.co.uk whose editor-in-chief, Dea Parkin, is based in Chorley (and is Secretary of the UK’s largest organisation for crime writers, the Crime Writers’ Association, which awards the famous Daggers for best crime writing.)
The first prize is £100, second prize £50 and there are three third prizes of £20.
Shortlisted entrants will be listed online and the winning stories will be published online and possibly in print.
Entry fee is £6 for one story or £10 for two.
Subscribed members of the Writers’ Circle are entitled to one free entry.
Entrants can live anywhere in the UK or be a British citizen living abroad.
The story mustn’t have been published in print before (online is fine) or won first prize in a competition.
Chorley crime writer DJ Harrison said: "We hope writers have fun writing a story with this very versatile theme in mind.
"Judging criteria are: – interpretation of theme; originality; quality of writing, for example pace, flow, characterisation, plot and style; and quality of prose, including grammar, spelling and punctuation.
"We hope that’s helpful and look forward to receiving your entry by 15 December."
People can enter by post or by email and pay their entry fee by cheque or by PayPal.
The Circle reserves the right to cancel the competition and refund entry fees if entries are insufficient to cover the prize fund.
Full rules and details on how to enter are at www.chorleywriters.org.uk under Competitions.


Dinosaurs are extinct today because they lacked opposable thumbs and the brainpower to build a space program.
I believe every human has a finite number of heartbeats. I don't intend to waste any of mine. That's one small step for [a] man, one giant leap for mankind.
We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically. There can be no thought of finishing for ‘aiming for the stars.’ Both figuratively and literally, it is a task to occupy the generations. And no matter how much progress one makes, there is always the thrill of just beginning.
For those who have seen the Earth from space, and for the hundreds and perhaps thousands more who will, the experience most certainly changes your perspective. The things that we share in our world are far more valuable than those which divide us.

Dynamic Java
A key part of MDW's support for cloud deployments and "Platform as a Service" architecture
is the ability to execute dynamic Java transparently in both local and remote environments. The Dynamic Java
Activity provides this capability.
For a detailed walkthrough of MDW Cloud development, see the MDW Cloud Cookbook.
Background
Dynamic Java takes advantage of the runtime compilation and execution framework built into JDK 1.6.
Compiled class definitions are lazily cached in the CompiledJavaCache as specified in the application cache configuration.
An important aspect of the Dynamic Java activity is that it enables you to transparently edit Java Code in a local
or remote environment without needing to redeploy or restart your server. You can also debug your code without
regard to where the workflow is hosted, setting breakpoints and viewing/changing variable values during process execution.
Usage
When you drag the Dynamic Java activity onto your process design canvas, you'll notice that the primary
attribute to specify is the Java Code itself. This content can be arbitrarily large, and can grow in complexity
along with the business logic you're implementing. Another important configuration aspect is the output (or writable)
documents list. Selecting a document variable as writable enables you to make changes to its value from within
your Java code (similar to the way Script Activities work).
To Edit the Java code, click the Edit link on the Java properties tab, or right-click on the activity and select Edit Java from popup menu.
If your workflow project is remote and it's the first time you've edited Java content in the project, you'll
be prompted to select a version of the MDW Framework Jars to download (see screenshot below). Your workflow project
will be converted to include the Java facet, and the framework libraries will be added to your project classpath.
This gives you access to all the standard Java editing capabilities built into Eclipse, with syntax highlighting
and autocomplete for the JDK classes as well as the classes provided by MDW itself.
When starting with a blank Dynamic Java activity, a skeleton implementation is generated by the plug-in to help get
you going (see screenshot). The classname in the generated code is based on the name you gave to the activity when inserting
it into your process, and its package name is based on the workflow package where the process resides. These conventions
are important because at runtime the class will be instantiated based on these same rules.
Your class must implement the JavaExecutor interface. See the code snippet below for an example of how this is used.
In this example, the process variables completionDate, dispensation, instructions, outcome and userMessage are interrogated and manipulated in various ways.
The return value from the execute() method dictates which outbound transition will be traversed when the activity completes.
Running and Debugging
When you're ready to test your Java executor, there's no need to compile or deploy; simply saving the artifact is sufficient.
As with all types of Workflow Assets, when you save the .java file you're actually saving a local
temporary copy, and this is persisted to the database once you save the process definition itself.
You can execute the process in the usual ways (by right-clicking in the process canvas and selecting Run, for example).
You also have the ability to debug your dynamic Java. To do this, simply set your breakpoint(s) in the usual Eclipse way,
and launch the process in debug mode (again by right-clicking on the canvas and selecting Debug, or by clicking the debug toolbar button).
Once launched, your breakpoint should be hit and you can proceed with stepping through code as you normally would in Eclipse.

Scotland is facing the coldest winter for ten years – with temperatures set to plummet to -13C
by Alistair GrantSCOTLAND is forecast the coldest winter for 10 years - with -13C lows, snow, ice and travel woes, with a weak sun and Arctic chills blamed.
The worst winter since 2009-10 is due as the sun is at the weakest point of its 11-year cycle of strength, said The Weather Company, the world’s biggest commercial forecaster.
The last time the sun's power was as low as now, Scotland saw the bitter 2009-10 winter, Britain's coldest winter since the 1970s, and the 2010 Big Freeze, with the coldest December ever recorded.
The Met Office says weak UV rays cause cold easterly winds rather than mild westerlies.
The forecast comes as Scotland faces rain then a -5C two-week 'polar plunge' starting from Friday.
The Met Office forecast cold polar air arriving from Friday threatening to remain for much of the next two weeks, with snow in the North and threatening the South.
Met Office forecasters say numerous factors point to cold weather this winter.
The worst cold with -13C lows will be between January and March, said The Weather Company, founded in 1982, which was bought by IBM for $2billion in 2016.
An average UK winter temperature 1.4C colder than normal, below 2010-11's 2.43C, would make this Britain's coldest winter since 2009-10's 1.64C, Met Office records show.
Leon Brown, head of meteorological operations at The Weather Company’s Weather Channel arm, said: “This winter is expected to be the UK's coldest since 2009–10.
“Solar activity is at a minimum this winter. Air pressure patterns are expected to allow cold Arctic air to affect Britain.
“Night-time temperatures of -13C are expected this winter. Travel will be affected.”
The Weather Company chief meteorologist Todd Crawford said: “We are quickly approaching the solar minimum.
The epic winters of 2009-10 and 2010-11 occurred during the last solar minimum. “We forecast the cold this winter to be focused in January and February.”
The Met Office forecaster Marco Petagna said: “Many things support cold weather this winter, including large snow cover over Siberia and Scandinavia, hints of weakening polar vortex winds and the solar minimum.”
The Met Office has said: “Low UV output from the sun can contribute to cold winters.
“In years of low UV activity, unusually cold air forms over the tropics and an easterly flow over mid-latitudes burrows its way down to the surface, bringing easterly winds and cold winters to northern Europe.”
