Federer Battles Isner In Miami Final; Championship Preview
by el-admin - March 30, 2019 March 30, 2019 0276
Fourth seed Roger Federer and seventh seed John Isner face off for the first time in four years in Sunday's final at the Miami Open presented by Itau. Federer leads their FedEx ATP Head2Head series 5-2, but given the trajectory of their careers since their last battle at the 2015 Rolex Paris Masters, won by Isner in a third-set tie-break, they will arrive on Stadium Court with a clean slate.
Since that match, Isner has earned a career-high ATP Ranking of No. 8 (in July 2018), reached his first Grand Slam semi-final (2018 Wimbledon) and picked up his first ATP Masters 1000 title last year in Miami (d. Zverev). He's now one match away from a successful title defence after powering into the final without dropping a set.
After undergoing knee surgery in 2016 and taking the second half of that season off to recover from it, some critics wondered whether Federer would get back to the top of the game. He's silenced them all by winning 12 more ATP Tour titles, including three Grand Slams, three Masters 1000 titles and his 100th tour-level title earlier this month at the Dubai Duty Free Tennis Championships (d. Tsitsipas). After surviving an opening-round scare in Miami against Radu Albot of Moldova, he's dropped an average of six games in his past five matches.

There will be no secrets when Federer and Isner meet. It's one of the best serves of all time against one of the best returns of all time. Almost all of their matches have been highly competitive affairs and Sunday's clash should be no exception.
"He's definitely got one of the serves that you basically can't read. It's that simple," said Federer. "You just hope that the stars align, that you pick the right side, he picks the wrong side, maybe he misses a serve, that you can put him in uncomfortable situations time and time again, and at the end somehow find a way."
Familiarity with the moment could play a factor. Federer is playing in his 50th Masters 1000 final (27-22), while Isner is competing in his fifth (1-3). It will be important for Federer to get off to a hot start as he's done in his past two matches against Kevin Anderson and Denis Shapovalov. If he can grab an early break, Federer will establish that that he can run away with the momentum.

Isner has been the tie-break king in Miami, winning nine of his 10 sets this fortnight with a 7-6 scoreline. His tie-break record against Federer is impressive, but less dominant at 4-4. Isner will need to take care of his service games and continue to keep the scoreline close. The deeper a set goes, the more the odds will favour him.
The American downplayed his chances at defending his crown at the start of the tournament, but his low-key approach didn't reflect his unwavering confidence that he could. While some fans may be surprised to see him produce another inspired run, Isner is not and believes he has the tools to leave Miami with back-to-back titles.
"I believe personally that I can win any tournament I enter because of how disruptive I can be and because of how well I can serve at times," said Isner. "I'm not surprised that I'm sitting here back in the final again."
Saturday's doubles final will see third seeds Bob Bryan and Mike Bryan pursue a sixth doubles title in Miami. The Americans take on Dutchman Wesley Koolhof and Stefanos Tsitsipas of Greece. Koolhof is playing in his first Masters 1000 final and Tsitsipas is competing in his first ATP Tour doubles final.

Q: os.Open on AppEngine with Go I've recently started playing a bit with AppEngine but I'm having problems opening a file. Here's the code I'm using:
if _, err := os.Open("/pizza.webp"); err != nil {
    printError(err.Error())
}

This gives me the error: open /pizza.webp: operation not permitted
I've tried using a .png instead and go the same result. I've also tried without the slash and with a dot before the slash, both resulted in the error no such file or directory so I'm guessing I have the path right but for some reason I don't have the permission to access it, maybe there's something I need to write in app.yaml? Right now app.yaml looks like this:
application: pizzarobot-telegram
version: 1
runtime: go
api_version: go1

handlers:
- url: /.*
  script: _go_app

Which is the default app.yaml with my application id. I've tried setting a static directory through app.yaml but that didn't work neither, I've read that AppEngine stores your static files apart from the code in that situation.
I'm also very new to Go so I might be doing this wrong way and might not be an AppEngine problem but I've used os.Open in the past without AppEngine and that worked so I don't know what I'm missing here.

A: It should work without the slash. File paths are relative to your project root (where your app.yaml is).
I just tried this with 3 files:
main.go
app.yaml
pizza.txt

main.go:
package main

import (
    "io"
    "net/http"
    "os"
)

func init() {
    http.HandleFunc("/pizza.txt", func(res http.ResponseWriter, req *http.Request) {
        f, err := os.Open("pizza.txt")
        if err != nil {
            http.Error(res, err.Error(), 500)
            return
        }
        defer f.Close()

        io.Copy(res, f)
    })
}

pizza.txt:
Totally Works!

app.yaml:
application: astute-curve-100822
version: 1
runtime: go
api_version: go1

handlers:
- url: /.*
  script: _go_app

It ran locally and on app engine.

Fort Collins marches to 'rise up and take action' for Dr. Martin Luther King Jr. Day
Carson Lipe
Fort Collins gathered to rise up and take action against the inequalities that still persist within the United States.
Around 800 citizens from all around Fort Collins marched through Old Town at the Martin Luther King Day March and Celebration titled Rise Up, Take Action ending with a rally in the Colorado State University Lory Student Center.

Participants ranged from a clusters of students from Poudre High School, to CSU students and faculty and to military veterans looking to support the cause.
During a congregation period prior to the march, participants shared words with each other and some spoke about what they thought the cause of this year's event was. One participant was CSU senior journalism Lena Ham.
"People are realizing that there are still issues in the world that we ignore, and [those issues] are still relevant and affecting people all over," Ham said.
The event kicked-off in Old Town Square, with a speech by the march leader, Jaelyn Coates, a master's student of student affairs in higher education at CSU. Coates dissected the meaning of a quote from civil rights activist Angela Davis.
"It was Angela Davis who said that you have to act as if it were possible to radically transform the world, and you have to do it all the time," Coates said. "And, now I ask you … what does it mean to be radical?"
Coates gave time for reflection on the true meaning of Davis' words. Coates also spoke about how something as simple as water access is not free and equal to all across the nation, giving examples of the disparity of living conditions amongst Americans lumped into different classes.
"Perhaps right now, there are many of us who could walk into any of these stores lining the streets of Old Town… and get a drink of water," Coates said. "But at this very moment there are also folks in Flint, Michigan and in Appalachia and in the Bayous of Louisiana who have been without [clean water] for years."

A few minutes into the march, chants rang out throughout the streets and those marching encouraged each other, while echoing the mantra of the march, "Rise up!" and "Take Action!"
Before the march began Susan Holmes disrupted the crowds precession. Holmes is the mother of Jeremy Holmes, who was killed by campus police. Holmes claims CSU President Tony Frank is avoiding her.
Towards the end of the march, the leaders and organizers of the event, along with Frank, locked arms and made their way into the Lory Student Center.
The keynote speaker was prefaced with a mix of poetry, speech and song. Frank spoke prior to the keynote.
"Those of us who have marched together over these years and come from positions of power and privilege, if we're honest, we know that we've marched in relative comfort and convenience," Frank said. "And yet, challenge and controversy have found us … but we do not face these challenges alone. There are those in our community who have never marched in comfort and convenience. We can draw on their strength and we can learn from them."
Frank used this quote to introduce the keynote speaker Rev. Jamie Washington.
The reverend stressed that while this MLK Day march may promote progressive thinking for the day, it is important for attendees to continue to assess their motives and to "wake up before you rise up."
After his opening speech the reverend dismissed the crowd into small groups where discussions were carried out on topics ranging from art and social justice to human trafficking.
As the event wore on, the crowd reduced notably in size prompting comments from the reverend before the closing of the day. The reverend instructed those who were still present to look around the ballroom and take note of the reduction of the crowd. He said this is a common occurrence.
"When you rise up and take action, people will leave," Washington said, to which the audience snapped in support. "I can't take all the action. Do your part."

Ancient technology survives in many strange ways. Atlatl sport is part of the current surge in recreational interest in "primitive skills." It is easy to learn to throw with an atlatl, but difficult to become expert. Simple and effective atlatls are easy to make. At the same time, some ancient atlatls (and some modern ones) are elaborate and beautiful, and there is a great deal of variation among forms and details of use. This combination of simple and esoteric, easy and challenging, makes spear throwers ideal for hobby use, and for teaching about prehistoric technology. Even novices can make and use an atlatl with satisfaction, but are also impressed with the potential complexity of preindustrial technology, and the skill and knowledge involved in using it.
Atlatls are about as safe as a projectile weapon can be, so they are excellent for teaching children under supervision. You can't kill someone with "didn't know it was loaded" stupidity or an accidental discharge. Range is short, and a miss will not fly for miles or penetrate brush or buildings. WAA promotes safety with the same kind of rules that should be taught for any target sport: targets are spaced, spectators controlled and no one throws at random or when anyone is downrange (See ISAC rules tab).
The atlatl can also involve students and the public in archaeological experimentation. There is a large literature on atlatls (see literature tab) students can research ethnographic and archaeological issues including diffusion of technology, stylistic and functional variation, inferring larger technologies from surviving fragments, social issues of weaponry and technological change, and the like. It is not hard to design and perform simple experiments with atlatls, and some of our understanding of atlatls comes from the experimentation of sporting atlatlists.
The WAA does not organize events, but promotes atlatling by spreading information, maintaining a calendar of events, scorekeeping one standard competition, and publishing a newsletter with competition results and atlatl news and science. Numerous local atlatl associations organize events, and help to promote communication among atlatl enthusiasts. There were more than 70 events in the US and Europe last year, some connected to other events, like history days, knap-ins, and rendezvous. The world of sporting atlatls is friendly and inclusive. Competitions include family members of all ages and are informal and supportive in tone. Super-athletes have not yet taken over!
Events typically include a number of target games, usually some widely used favorites like the ISAC,the European Round, or the "American Field Round" plus some quirky local games such as moving targets or 3-D "hunts". The International Standard Accuracy Competition (ISAC) was invented by Lloyd Pine in 1996 to allow comparison among atlatlists all over the world. The ISAC is the longest running standardized event, and one of the few for which rules are carefully obeyed and records maintained. Even here, participants at all levels are welcomed, and awards given for Men, Women, and Youth participants competing under the same standards. Most events explicitly try to attract spectators and give anyone who wants a chance to try an atlatl. If they show the slightest interest, we encourage them to join the events.
Many atlatlists are interested in hunting with spear throwers, currently only legal for some game in some states. A number of local organizations are attempting to legalize atlatl hunting in their states. Wildlife authorities have legitimate concerns about safety and humane killing of game, but the safety and efficiency of the atlatl is easily demonstrated, and a number of atlatlists have successfully taken deer, boar, small game, and fish. After all, spear throwers were used all over the world for thousands of years to kill animals up to the size of elephants. The WAA does not actively lobby, but does attempt to provide accurate information and communication to support those involved in legalizing atlatl hunting.
Below are documents prepared by Ron Mertz regarding the efforts of the Missouri Atlatl Association to legalize the atlatl for hunting in Missouri.

The biggest community event of the year along the F-line is coming up: the Castro Street Fair on Sunday, October 3. We need volunteers to man our "booth," which will be Muni's oldest streetcar, No. 578, a San Francisco car built in 1895. We are seeking volunteers to staff the booth where we will be selling merchandise and recruiting new members. Hope you can make it for all or a portion of the day.
One of our biggest objectives at Market Street Railway is to get the word out to the neighborhoods along the F-line about the role we play in keeping the F-line streetcars in service and looking good. Most people don't know that our advocacy was a key factor in replacing the old bus service to Castro with the attractive F-line streetcars 15 years ago, and is still critical to ensuring that Muni allocates enough resources to keep the streetcars running properly.
This is one of the best street fairs in the city, and certainly one of the most fun. So come out and volunteer with us for a couple of hours, then enjoy the fair! If you're able to help, please email volunteer@streetcar.org and let us know.
In any event, come by on October 3 and meet with us. We'll have unique streetcar merchandise including our 2011 Museums in Motion calendar and popular "Information Gladly Given, But Safety Requires Avoiding Unnecessary Conversation" t-shirt.
← F is for Fifteen: Happy Birthday, F-line!

Impressions, ideas and insights from the library scene in the United States and Germany.
After listing the Top Ten Library Stories 2008 from the viewpoint of the American Library Association (ALA), I would like to add my personal library related highlight of the year: since November 2008, the 'libraries' of the Goethe-Institut can be called 'libraries' again. For a number of years we made a great effort to point out that they are Information Centers and not 'only' libraries. The reason for the return to the old and established term 'library' was that libraries today are much more than mere 'book depositories', but offer a wide range of services that include real and virtual prospects.
Of course the Goethe-Institut is not the only one struggling with the nomenclature. Because even if it's decided that it is a library in which you work, there are still endless possibilities for job titles. Michelle Mach lists an impressive number of Real Job Titles for Library & Information Science Professionals.

About Gravenstein apple Edit
Wikipedia Article About Gravenstein apple on Wikipedia
This crisp, juicy, sweetly tart apple has a beautiful green skin streaked with red. It's in season from August to late September and available mainly on the West Coast. Although the Gravenstein is considered an all-purpose apple and makes delicious pies and applesauce, it does not do well when baked whole.
Gravenstein (Danish: Gråsten-Æble) is a variety of apple native to Gråsten in South Jutland, Denmark, although there is some evidence that the variety originated in Italy and traveled north.
The Gravenstein apple is considered by many to be one of the best all-around apples with a sweet, tart flavor, and is especially good for baking and cooking. It is picked in July and August and is known as a good cooking apple, especially for apple sauce and apple cider. It does not keep well, and so is available only in season. In addition, their short stems and variable ripening times make harvesting and selling difficult.
Most Gravenstein apples have a delicate greenish skin streaked with red, but a few trees produce classically red apples. These red apples, commonly known as Red Gravensteins, are considered a sport rather than a true variety.
The Gravenstein was introduced to North America in the early 19th century, perhaps by Russian fur traders, who are said to have planted a tree at Fort Ross in 1811. They are found most widely on the west coast of the United States, and in particular, in Sonoma County, California. Luther Burbank praised the apple, "It has often been said that if the Gravenstein could be had throughout the year, no other apple need be grown."
During the first half of the 20th century, Gravensteins were the major variety of apples grown in western Sonoma County, and were the source for apple sauce and dried apples for the U.S. troops in World War II. Most of the orchards in Sonoma County are now gone due to a combination of suburban development, a shift to wine production, and economic changes in the apple industry. Only six commercial growers and one commercial processor remain in Sonoma County as of 2006. In 2005, Slow Food USA declared the Gravenstein apple a heritage food and included it in their Ark of taste. Slow Food USA reports that production in Sonoma County is currently 750,000 boxes (15,000 tons) of Gravenstein a year; a third of the fruit (250,000 boxes) is of premium market quality.

A new key to help treat different cancers: Study
Scientists at Yale Cancer Center in the US have uncovered the workings of a metabolic pathway or "gauge" that lets cancer cells detect when they have enough nutrients around them to grow.
The researchers hope that drugs designed to turn down the gauge may eventually aid in treating many forms of cancer.
"The cancer cell has an unlimited appetite for nutrients," said Xiaoyong Yang, Associate Professor at Yale Cancer Center and senior author of the study.
Xiaoyong Yang"But in many parts of the body, especially for solid tumours, nutrients and oxygen are often limited, so the cell has to make a decision to grow or survive.
We have shown how the cell adapts to its microenvironment, detecting nutrient availability to make this decision."
Yang and his colleagues studied the role of a process called O-GlcNAc protein modification in cancer metabolism.
O-GlcNAc modification alters the function of proteins by attaching certain kinds of sugar molecules and is thought to generally act as a nutrient sensor for the cell.
"We were interested in this modification because it is a common feature across many types of cancer," Yang noted.
The team began by examining a wide range of human cancer tissue samples for signs of O-GlcNAc modification, including levels of expression for the OGT and OGA enzymes.
They found that both OGT and OGA are expressed at higher levels in many cancers than in normal tissues.
Their findings were published in the journal Oncogene.

Q: Jupiterlab inline plot The code below was executed in notebook opened in Jupyter Lab (not Jupiter notebook), but it didn't show the plot.
Does anyone else have this problem? Did you need to run special command to enable inline plotting in Jupyter Lab?
input:
fig = plt.figure(figsize=(10,6),facecolor="white",dpi=100)
ax = fig.add_subplot(111)
ax.plot([1,2,3],[4,5,6])
plt.show()

output: FigureCanvasNbAgg().

A: Just add %matplotlib inline somewhere in the notebook and you should be fine

Q: Less/Sass debugging in Chrome Dev Tools/Firebug How do you guys do maintenance on CSS built with Less/Sass?
One of the things I like about Dev Tools/Firebug is the ability to see the line number of a css styling. Is there a good way to do this with CSS preprocessors other than having to manually search through the .less/.scss file to find the code I want to modify?

A: Chrome Developer Tools now supports Sass debugging out-of-the-box.
Updated to include source maps:
Previous versions used inline comment in your css to provide a refernce to the source code (see below how-to). recent versions of sass (3.3+) and chrome (31+) use source maps for that:

*

*Make sure you have Sass 3.3.x

*Compile your Sass with the --sourcemap flag.

*In Chrome/ium DevTools open settings and click general.

*Turn on "Enable CSS source maps".

More info is available on the Chrome dev tools blog:
https://developers.google.com/chrome-developer-tools/docs/css-preprocessors
Older versions:
 1. First, you should compile your Sass with --debug-info turned on.
 2. In Chrome/ium go to about:flags
 3. Enable Developer Tools experiments
 4. In your inspector (F12), open "Settings", then go to the "Experiments" tab
    and check "Support for SASS".

A: If you're making a choice as to which you should be using, this article on css-tricks might be of interest to you.
I have come to experience that using LESS or SASS has more advantages than disadvantages. Though this is certainly a disadvantage I can only suggest you structure your files well so any styles you seek are easily found using other references, here are a few things you can do:

*

*Document areas of your stylesheet; ie /* General */, /* Header */ and /* Footer */

*Use logical and sensible names for classes you can recognize quickly (and don't number them like error1-error10 or something)

*Learn to dissect the class/element/id selectors and think about how/where you would have written them.

*Use CTRL+F, often the precise attribute or one near it is fairly easily found this way

SASS
There is now a way to debug SASS in firefox using an extension that reads and displays the sass files in the firebug inspector. To use, install the extension and enable the respective debug flags.
https://addons.mozilla.org/en-US/firefox/addon/firesass-for-firebug/
Edit: as of 2014-07-06, this plugin is no longer available for download. FireSass has been discontinued.
Chrome/Webkit versions have been popping up around the net and theres a beta feature in chrome to add support for SASS debugging. It's based on the same debugging information used in the firefox version. Haven't been able to judge any of them properly as of yet, nor found something which is publicly accepted as being the plugin for the job as of this writing.
LESS / STYLUS
As this tweet @jaketrent points to explains, there is progress on the debugging side in chrome, but nothing baked in yet and given the state of the LESS github it might still take a while... Both solutions are based on the beta feature for SASS debugging support in chrome, basically adding the same debug information as SASS does.

*

*https://github.com/cloudhead/less.js/pull/1038

*https://github.com/LearnBoost/stylus/pull/886

A: I rarely have issues with maintenance/debugging in LESS -- we always compile on the server end and reference only the CSS file in the HTML page.  This makes it so there's always a one-to-one correspondence with the webpage and a file on disc.
And then when I have to edit the LESS file, I find that LESS, since its pretty much CSS+extra markup, it's quite easy to backtrace anything I'm confused about to the originating statement in CSS.  If it's a mixin, it's pretty obvious (since I usually use mixins to prevent having to do all the vendor prefix stuff repeatedly), and then it's just a logical hierarchy since we use the class nesting feature, so finding:
div#awesome aside ul
is as easy as finding:
div#awesome{
    aside{
        ul{
            padding: 0;
        }
    }
}

(although we try to not go more than 3 layers deep)
I have no real experience with SASS but I didn't like how far removed from CSS it was when I first looked at it a few years back (and haven't been back since...)

A: Some tips:

*

*Include both the .sass and the .css files in version control. This way everyone has the most current changes.

*If you organize your stylesheets into logical areas, maintenance is a breeze.

*Also: try to use fewer than three main colors, and then use SASS color functions to modify them and store results in variables that you can reuse throughout your design/theme.

Ex:
$chartreuse: #7fff00
$olive: darken($chartreuse, 32%)
That way, you only have to maintain one color. And the rest will be recalculated.

Until recently, there were no in-browser SASS debugging tools.
There is now a Firefox plugin called FireSASS (https://addons.mozilla.org/en-US/firefox/addon/firesass-for-firebug/)
In your sass --watch command, add a -g for --debug-info so that it will output the hooks needed for the plugin to run.

A: I switched from less to sass, because of firesass.
With this you get the original sass line in firebug.
install firesass if you use sass

Hugh Hefner remembered on the Walk of Fame
(photo by Luke Harold)
Playboy founder Hugh Hefner died on Sept. 27 at age 91.
Hefner published the first issue of Playboy Magazine with $8,000 from more than 40 investors, including his mother. He became a champion of free speech and liberation, and eventually a target for criticism as the women's rights movement entered the mainstream.
Hefner planned to be cremated and for his ashes to be interred in the crypt next to Marilyn Monroe, the first Playboy cover model, at Westwood Memorial Park in Los Angeles.
The Hollywood Historic Trust placed flowers on Hefner's star, located in front of the Roosevelt Hotel at 7000 Hollywood Blvd.

Hundreds of songs have gone through the past 63 editions (Eurovision 2019 will celebrate number 64). Many have fallen into oblivion, others are still remembered as part of the festival and others have been famous for themselves and they have even been remixed or versioned by other artists.
"Volare", Domenico Modugno (1958). Many will not know that this popular song by Domenico Modugno (also known as "Nel blu dipinto di blu"), swept the San Remo festival and later won the Eurovision Festival in the spring of 1958.
"Poupée de cire, poupée de son", France Gall (1965). It is another of the great known of the eurofestival. He won the 1965 edition thanks to the interpretation of the French singer (now deceased) France Gall.
"Puppet on a string". Sandie Shaw (1967). Barefoot and strong, the British Sandie Shaw came on the scene and with "Puppet on a string" achieved the first triumph for the United Kingdom. The popular theme was also covered in Spanish: "Marionetas en la cuerda".
"Congratulations", Cliff Richards. (1968). Behind Massiel, in second place was the popular theme of the British Cliff Richards, who would return years later (in 1973) remaining in third position.
"Waterloo", ABBA (1974). Some very young Anni-Frid, Benny, Björn and agnetha ("ABBA"), won with "Waterloo" the 1974 Eurovision Song Contest. More than a battle, it was a complete conquest, because that Swedish group would become years later, in a of the most popular Pop bands in the history of music. Their lyrics, music and songs would be recognized by millions of people, while hitting the sales lists around the world.
"Save your kisses for me", Brotherhood of man (1976). It is another milestone in the history of the festival. With a nice staging, the British quartet won the victory in The Hague, giving the United Kingdom its third victory in the eurofestival.
"A-Ba-Ni-Bi", Izhar Cohen & ALphabeta (1978). In 1998, the Catalan artist Marc Parrot (also called "El peval de la peca") released a version of the song "A-Ba-Ni-Bi" and popularized this song that twenty years earlier, the Israeli Izar Cohen had played in the 1978 edition, giving the first triumph for Israel in the whole history of the festival.
"What's another year?", Johnny Logan (1980). The one that would become one of the most popular musicians of the festival, was presented for the first time in 1980, in The Hague. The ballad ("What's another year?) Captivated the jury, which surrendered to Logan, giving the second triumph for Ireland.
"Love shine a light", Katrina and the waves "(1997). The British group that in 1983 jumped to fame with "Walking on sunshine", breaks into the Eurovision in the spring of 1997 and wins the festival in what would be the last victory for the United Kingdom.
"Diva", Dana International (1998). The Israeli transgender Dana International generates a great expectation in the 1998 edition, obtaining the victory for Israel and giving her country, the third victory in the history of Eurovision.
"My number one", Helena Paparizou (2005). The Greek settled in Sweden Helena Paparizou, in Kiev achieved the first victory for the Hellenic country. "My numer one" also enters the top of the best songs of the festival in the contest that was made to commemorate the 50th anniversary eurovision.
"Fairytale", Alexander Ribak (2009). The city of Moscow hosted the festival, in what has been considered the most expensive and spectacular of all editions to date. On the immense and majestic stage, shone (violin in hand) the young Belarusian origin Alexander Ribak, who with "fairytale" gave the triumph to Norway.
"Euphoria", Loreen (2012).It is undoubtedly the most popular Eurovision song of this century. The theme played by the Swedish-born Moroccan Loreen, swept in the Melodifestivalen (Swedish festival where the representative for Eurovision is chosen) and later, it did in Baku in the Grand Final. Not only did he win, but "Euphoria" took over the dance floors of half of Europe, including, his notes were played by the guard band of the Royal Palace in Stockholm.
"Rise like a phoenix", Conchita Wurst (2014). The Austrian Thomas Neuwirth, came to Eurovision from the hand of his alter ego, Conchita Wrust. The character faced by Neuwirth, had a very feminine appearance: gala dress in golden tone, dark hair, long and molded, but without detaching himself from his bushy and perfectly cropped beard. "The bearded woman" (as I call her part of the public opinion) won with "Rise like Phoenix" by launching a message in favor of freedom, tolerance and sexual diversity. "We are unstoppable" ("We are unstoppable"), said Conchita after receiving the award.
"Toy", Netta (2018). The artist Netta Barzilai was discovered in a television program, surprising by using a looper (device used to play sound tracks that are made with the voice and can be repeated simultaneously as a sampler). The Israeli came to the last edition of Eurovision with "Toy" but without looper (EBU regulations prevent using live instruments, considering this type of device as such). Even so, he devastated and gave the fourth victory to Israel.

The Squad Building Challenges of FIFA 19 Ultimate Team continue! This time it is the turn of the FIFA 19 Premium SBC dedicated to the goalkeeper PETER CECH and TIM HOWARD that at the end of the season will hang, as they say, the shoes to the nail withdrawing from the competitive activity. Still, Goldkk.com will provide you with information about the requirements, rewards, cheap squads builder and solutions of each SBC throughout the FIFA 19 Tim Howard Premium SBC and FIFA 19 Petr Čech Premium SBC!
This is the special version, called "End of an era" in the past with the Premium SBC card to celebrate the retiring players' career, we have seen use in the past few years for example for Francesco Totti, Andrea Pirlo and Daniele De Rossi. Now it returns to FUT 19 with Petr Cech and Tim Howard Premium SBC. Recall that in many cases it is more convenient to try to use the cards that you have within your club, taking inspiration from the players used in the solutions on FUTBIN (same nationality, same league, same role) but not using exactly the same they could often be priced higher, inflated by the fact that many people buy them with FIFA 19 Coins to complete the challenges. Now follow us to check details and possible cheapest squads builder to get the 91 Petr Čech and 89 Tim Howard.
Arsenal goalkeeper Petr Cech has announced that he will be retiring at the end of the season. Tributes to Cech, who stands as one of the greatest goalkeepers of the Premier League era, have flooded in since news of his impending retirement.
The United States international and former Everton goalkeeper Tim Howard has announced he will retire following the 2019 Major League Soccer season. He has enjoyed a distinguished career that saw him feature at Manchester United and Everton, as well as star at the World Cup for his national side.

Q: optimizing functions (memory) in lisp - trie data structure I'm a lisp beginner and I'm trying to write a package that defines a class for a trie and reads the entirety of the scrabble dictionary in to it. The struct acts as a node, each of which has an association list that keeps track of letters that stem from it (leading to other subtries).
Here is my code for the class
(DEFCLASS n-trie ()
  ((word :accessor word
         :initform 'nil
         :initarg :word)
   (word-count :accessor wcount
               :initform 0
               :initarg :wcount)
   (next-letters :accessor next-letters
                 :initform 'nil
                 :initarg :next-letters)))

Here is my add word function
(defun add-word (string trie) ;;iterative method for looping through string
  (let ((s (coerce string 'list))
        (tri trie))
    (dolist (item s)
      (cond
       ((assoc item (next-letters tri))
        (incf (wcount tri))
        (setf tri (cdr (assoc item (next-letters tri)))))
       (t
        (incf (wcount tri))
        (setf (next-letters tri) (acons item (make-instance 'n-trie) (next-letters tri)))
        (setf tri (cdr (assoc item (next-letters tri)))))))
    (setf (word tri) string)))

and here is the function that opens my file (scrabble dictionary) and reads each line
(defun read-words (file trie)
  (let((str (open file)))
    (labels ((rec (tri)
                  (let ((line (read-line str nil nil)))
                    (cond
                     (line (add-word line tri)
                           (rec tri))
                     (t (close str)
                        trie)))))
      (rec trie))))

Whenever I try to load the entire dictionary, I get a stack overflow. There are over 100k words in the scrabble dictionary, and it's failing at 6000...something is wrong with my memory usage, but I can't seem to tell what.
Is there something that I am doing in these definitions that is inherently expensive memory-wise? I tried making the trie node a struct instead of a class, and got similar results. I also had a recursive algorithm for adding a word from the dictionary, but it was just as bad.
I've been struggling with this for hours, and i'm a little frustrated...

A: The first thing I would change is the function read-words. It uses tail-recursion and looks like in Scheme. That's not idiomatic in Common Lisp. Use WITH-OPEN-FILE to open a file and use a loop construct to read the lines. If the Common Lisp system does not optimize the tail recursion, this recursion already creates a stack overflow on large text files.
So:

*

*don't use tail recursion, where not necessary and where you know that your CL implementation actually supports it and understands it. For example high debug modes usual prevent tail recursion optimization.

*use WITH-OPEN-FILE. Don't use OPEN/CLOSE.

*use IF instead of COND - especially when we deal with a normal true/false predicate.
