Abstract: This paper presents a study of the local radio source population, by cross-comparing the data from the first data release (DR1) of the LOFAR Two-Metre Sky Survey (LoTSS) with the Sloan Digital Sky Survey (SDSS) DR7 main galaxy spectroscopic sample. The LoTSS DR1 provides deep data (median rms noise of 71 μJy at 150 MHz) over 424 square degrees of sky, which is sufficient to detect 10 615 (32 per cent) of the SDSS galaxies over this sky area. An improved method to separate active galactic nuclei (AGN) accurately from sources with radio emission powered by star formation (SF) is developed and applied, leading to a sample of 2121 local (z < 0.3) radio AGN. The local 150 MHz luminosity function is derived for radio AGN and SF galaxies separately, and the good agreement with previous studies at 1.4 GHz suggests that the separation method presented is robust. The prevalence of radio AGN activity is confirmed to show a strong dependence on both stellar and black hole masses, remarkably reaching a fraction of 100 per cent of the most massive galaxies (> 1011 M☉) displaying radio-AGN activity with L150 MHz ≥ 1021 W Hz-1; thus, the most massive galaxies are always switched on at some level. The results allow the full Eddington-scaled accretion rate distribution (a proxy for the duty cycle) to be probed for massive galaxies, and this accretion rate is found to peak at Lmech/LEdd ≈ 10-5. More than 50 per cent of the energy is released during the ≤2 per cent of the time spent at the highest accretion rates, Lmech/LEdd > 10-2.5. Stellar mass is shown to be a more important driver of radio-AGN activity than black hole mass, suggesting a possible connection between the fuelling gas and the surrounding halo. This result is in line with models in which these radio AGN are essential for maintaining the quenched state of galaxies at the centres of hot gas haloes.

The dramatic decrease in price and increase in availability of hobbyist electronics has led to a wide array of embedded and interactive devices. While electronics have become more widespread, developing and prototyping the required circuitry for these devices is still difficult, requiring knowledge of electronics, components, and programming. In this paper, we present Trigger-Action-Circuits (TAC), an interactive system that leverages generative design to produce circuitry, firmware, and assembly instructions, based on high-level, behavioural descriptions. TAC is able to generate multiple candidate circuits from a behavioural description, giving the user a number of alternative circuits that may be best suited to their use case (e.g., based on cost, component availability or ease of assembly). The generated circuitry uses off-the-shelf, commodity electronics, not specialized hardware components, enabling scalability and extensibility. TAC supports a range of common components and behaviors that are frequently required for prototyping electronic circuits. A user study demonstrated that TAC helps users avoid problems encountered during circuit design and assembly, with users completing their circuits significantly faster than with traditional methods.

Michelin Ginetta GT4 SuperCup Brands Hatch
Earl Karanja
Brands Hatch; a Kent staple. This place offers just about anything and everything when it comes to Motorsports. Whether you're a simple spectator or a professional racer; Brands Hatch is a great day out. On Saturday the 29th of March I was offered the chance to go to Brands Hatch with a colleague, watch some of the races and even interview the participants.
As with any sport, publication and press is a key part of the business and this was evident in Brands Hatch's media tower. In the tower; press, bloggers, sponsors and racing enthusiasts gathered to Blog and Tweet about the races and various events that would be taking place that very day. In that building your ears are never far from the frantic clicking of keyboards and mice. At the top of the tower was the broadcasting studio for the popular "Brands Hatch Radio" which provided excellent commentary for both the listeners and the spectators at the park.
After exploring the Media Tower we had the chance to walk down to the paddocks and interview some of the racers who would later be competing against each other. Our first victim was 17 year-old Charlie Robertson, who would be competing in the 2014 Michelin Ginetta GT4 SuperCup which was set to take place later that day. Our conversation with Charlie gave us some insight into what makes a racer.
Charlie told us that he'd wanted to be a racer since the age of 8 and that his biggest aspiration was to make racing his career. We spoke to him just after the qualifying round for the SuperCup. Robertson currently held the 5th position at a time of 47.920 seconds (a mere 0.176 seconds behind the holder of the coveted pole position: Andrew Watson). His vehicle had suffered a component failure during the race which may have cost him a higher place.
Regardless, we were very grateful that Charlie gave us a moment of his time and wish him luck in his future races. As we continued through the paddock we managed to grab some time with the holder of the pole position. Mr Andrew Watson, a 19 year old racer managed to snag 1st the qualifiers with a time of 47.744. We asked Watson many of the same questions we asked Robertson. Watson told us that he'd been interested in quads and cars since the age of 6. When we asked him about his aspirations about his future in racing he stated:
"I'm not sure; I haven't won a race in the SuperCup yet. If I can do that this afternoon then you can come back and ask me"
Our next encounter with Charlie and Andrew would have to wait until the conclusion of the SuperCup. In the meantime we were able to observe some of the races, including one from the top of Hatch's media tower.
Near the middle of the afternoon we returned to the Media Tower to watch the long awaited Michelin Ginetta GT4 SuperCup. Within the first few laps Andrew had sailed into first place over taking 18 year old Pepe Massot who had sadly lost his place in the race by midpoint due to a black flag. The race continued with Andrew claiming his Maiden Win in the 2014 Michelin Ginetta GT4 SuperCup.
Charlie Robertson, keen on claiming a place in the top 3 snagged a solid 3rd place. At the race's conclusion we made our way down to the podium where we saw both Watson and Robertson being awarded their respective trophies and celebratory champagne.
In summary; the day gave us a lot of insight into what goes one behind the fast cars. Being able to see the press and bloggers in action showed how dedicated the organisers and followers of racing are. Being able to interview and socialise with the racers showed us how respectable the racers are and that they have real aspirations besides the fame that comes with the job. In conclusion, it was a brilliant experience and I can definitely say that I have learned something during my short time at Brands Hatch.

How The Horror-comedy Film Genre Defined The 2010s Decade
You need to not take any action or stay clear of taking any action without the need of consulting with a qualified mental wellness skilled. Good vibes develop a optimistic mindset, collectively with a happy feeling and private satisfaction. Laughter can support lessen depression and anxiousness and could make you really feel happier. Laughter canease pain by causing the body to make its own all-natural painkillers. Nevertheless, over the past eight years, she has observed extra comedians — some well-known, some open mic-ers — taking on climate themes.
And as is typically the case for newly formed categories, stand-up's diversity of voices, styles and tones has developed all kinds of new, or at least newly thought of, sub-genres and concepts. One particular usually requires a bit of comedy just to get by way of the day. One tries to come across this comedy in the type of the motion pictures one particular watches, the points 1 observes and even the individuals 1 chooses… Black comedy or dark humour is the sort of comedy that presents significant things in a rather light manner. The lieutenant of Inishmore by Martin Mcdonagh and The 'Shape of Things' by Neil Labute focus on the use of black comedy to evoke laughter and…
Comedians are an fascinating bunch, and I have considerably to say about them. On the surface, the genre personality suggests an outgoing student who attracts attention by becoming funny. But I assume lots of Comedians worry about their reading skills, and as a result, are often quiet, somewhat shy, and sensitive. Performers at The Improv Space staged the absurd scene for "Ladies' Evening," a two-hour show that capabilities an all-females cast of stand-up comedians, improvisers and performers.
In addition to his stand up shows, Connolly has also appeared in numerous films including PocahontasandThe Hobbit. I mentioned 'No, but I want a regular banana later, so… yeah.' Much like Steven Wright, Mitch Hedberg was a master at delivering absurd one-liners, often by means of closed eyes and shaggy hair. His gem-to-dud ratio was insanely higher, generating his death at the age of 37 even more of a painful loss. Dark, jaded, and hyper-essential of common culture, religion, government, and generally his audience, Bill Hicks under no circumstances had mainstream appeal, and he was fine with that. His shows had been spiked by angry rants that, if they didn't contain so substantially depth, you'd have sworn they have been the function of a madman. His tragic death from cancer at age 32 reduce brief a profession that was 100% special and unapologetic.
In a lot of methods, the film was ahead of its time in that it depicted an atypical household dynamic. In the end, the husband and wife do not get collectively as a delighted ending, but it does discover a way to at least have a happy ending for the sake of the youngsters. In the '90s, that meant that comedians such as Jim Carrey, Adam Sandler, Robin Williams, and other people dominated the film landscape. These courses lay the foundation for your creative course of action. Students are immersed in the strategies of The Second City, learning how to use improvisation as a tool for collaboration and content generation. Students screen comedic performs from a variety of media and eras to improved inform their function as comedic storytellers.
It's not possible to sum up the strange shenanigans Napoleon gets up to—the liger doodling, the tater tots, and of course his "Vote for Pedro" dance performance—it's one thing you have to see for yourself. In this irreverent dark war comedy that spawned the Television series, a team of womanizing, freewheeling, heavily-drinking army medical doctors treat wounded soldiers and break guidelines left and suitable as the Korean War rages around them. Noah Baumbach's emotional juggernaut showcases profession-best function fromAdam DriverandScarlett Johansson.
I guess it boils down to significantly less slapstick/dick jokes and far more wordplay, references, and situational humor, which I vaguely keep in mind reading getting INTJ's preferred varieties of humor. If you or an individual you know is possessing a tough time and requires some further help and support, there's nothing at all wrong with speaking to a counselor about how you really feel about life, happiness, and your personal objectives. Research have indicated that on the internet therapy services like BetterHelp have yielded an typical of 70% reduction in symptoms amongst clients with depression. In reality, 78% of BetterHelp users who had severe depression prior to treatment were no longer classified as obtaining extreme depression post-treatment. In contrast, bonding humor's aim is to endear others to you. Speak show hosts on tv may possibly use amusing anecdotes, witty banter and down-to-earth humor that unites lots of unique men and women in a funny moment.
"My Man Godfrey" is a single of the very best comedies and social commentaries of the 1930s. In "Gentlemen Prefer Blondes," Marilyn Monroe and Jane Russell play two showgirls and most effective buddies on a cruise. Lorelei is bubbly, obsessed with diamonds, and way smarter than she looks. Dorothy would take a bullet for her pal, even when her social-climbing hijinks get in the way of her chance to ogle the complete U.S. men's Olympic team . "Gentlemen" may perhaps be in the title, but the most significant joke of the film is that at no point does it seem that Lorelei or Dorothy particularly care what they prefer. All that Daniel desires to do is give his father a good, respectable funeral, but it seems like the complete planet is conspiring against him.
By way of Tribeca Productions, De Niro develops projects on which he serves in a combination of capacities, such as producer, director and actor. Robert De Niro launched his prolific motion image career in Brian De Palma's The Wedding Celebration in 1969. The video of the incident she uploaded on Twitter the subsequent day has been viewed over 5.five million occasions. Inevitably, there will be some adverse evaluations my latest blog post, but aspiring comics need to have to be capable to look beyond these and focus on positive word of mouth and sold-out gigs. Take our cost-free profession test to obtain out if comedian is a single of your major career matches.
Russell Brand posted a photo of Katy Perry with no makeup. Each of these circumstances could inspire incredibly funny sketches. You'll soon start off receiving the latest Mayo Clinic wellness facts you requested in your inbox. Come across a way to laugh about your personal conditions and watch your pressure begin to fade away.
Things get wildly out of hand, but the ordeal ultimately becomes inspiring and somehow superior for the careers of the 3 instigators. The Authurian legend get the parody therapy in this absurd—and endlessly quotable—cult classic in which the Monty Python players star as the Knights of the Roundtable on the search for the legendary treasure. The Coen Brothers teamed up with the streaming service for this Netflix original, an anthology film featuring six stories set in the American west that is full of outlaws, pioneer women, double-crossing, and one particular singing cowboy. A bit a lot more on the serious side, Okja is a lot more of a satire than it is a complete-fledged comedy.
A whirling dervish of madcap power and silliness, Mandel created playing the fool serious business. No one particular could blow a rubber glove atop their head with their personal nose very like him. As his popularity soared, Mandel mostly left the props and voices behind. What was left was a sensible, insanely likable comedian, but in no way any much less the showman.

What are the Most Durable Hardwood Floors for Kids?
Designing homes for homeowners is no walk in the park. While it may be rewarding at times, there are so many things to think about. Things such as which type of flooring will hold up over the years.
This aspect is can be difficult when you add the idea of children. They can be playful and rough on flooring. And when you're designing around the probable factor of kids, its important to plan carefully. That's why you need to know the most durable hardwood floors for a household that may have kids.
Not all hardwood floors are created equal. Read this list of floors that are definite winners in the domestic hardwood category.
Black walnut hardwood floors are very durable. It has a moderate hardness score (1010) on the Janka rating scale and doesn't show scratches as easily if finished with low gloss or matte polyurethane.
Aside from its durability, Black Walnut is also versatile. The color and visual texture make it easy to match with almost any theme you choose to use in a house. Maintenance isn't difficult, either. You'll love how long this hardwood flooring lasts.
Even though its harder than some other species its readily available, easy to work with, and affordable. It's also more available than some of the exotic wood types. If you are considering resale it also has wider popularity than exotics.
When you put in hardwood flooring, you think about its future. With oak, you don't have to worry as much. Because of the grain of this wood, it's great at camouflaging flaws. Scratches, dents, and other flaws aren't as noticeable.
There are different types of oak from which to choose. Red and white oak are both great choices, it's only a matter of what you want. Red oak is going to have a more red or pink tone, even after staining.
White oak flooring is a more versatile option. It's lighter, and matches to design themes much easier. White Oak is by far the most popular option for new builds.
Hickory wood ranks pretty high on the Janka hardness scale (1820). That means it's durable and will last a very long time. It's one of the most durable domestic options you can find.
The downside to installing hickory in a home is that it's not as affordable as oak or some other common wood. Though, it would still be quite the statement piece in any home. The natural variation between heart and sap wood in Hickory gives it the distinctive look that makes it so popular.
The most durable hardwood floors are sometimes the most beautiful. Make sure to talk with your flooring consultant about what floors will work the best for you. Planned well they will last a lifetime.
Durability is one thing, but lasting beauty is another. Maintaining hardwood flooring should not be a task that's taken lightly. If you maintain hardwood flooring, it will stay healthy and last for years.
Whenever you're ready to install hardwood floors in a new home, contact us. Our portfolios are full of flooring options to fit any house.

Pro Wrestling will never again feature stars like Dwayne Johnson, Steve Austin and John Cena
Today's WWE is vastly different from the wrestling in the Attitude Era or the era of Ruthless Aggression. Controversial and extreme storylines are gone, and so is the blood. WWE is now a worldwide entertainment, and it needs to be PG. What this means is that the current era has to tend to a wider variety of audience. The thing that changed the most unfortunately are the stars, as nobody reached the levels of Stone Cold Steve Austin, The Rock or John Cena.
WWE Hall of Famer Bully Ray, also known by his WWE stage name Bubba Ray Dudley, appeared on the Jim Ross Podcast where he discussed wrestling. He criticized the quality of Raw, saying how the storylines became worse. In addition, he revealed the cause behind the lack of stars and why there will never again be someone like that.
"Seth Rollins has done it all and can do it all. But how come Seth Rollins is not at Cena level? How come he's not at Rock level? How come he's not at Austin level? It's because I don't think they will ever allow anyone to get to that level again. If you take the three biggest stars over the last 20-some-odd years, would you say that Cena, Austin, and The Rock are the three biggest ones? Okay, so those three guys in their own way do what they wanted to do without Vince's approval. Listen, Steve was able to walk out and still come back and have a job. [Ross] helped out a lot, but not a lot of people walk out and come back in the next day."
"Rocky was able to walk away and become the biggest star in Hollywood. And John, my God! He just won the Muhammad Ali Award. He [has] granted more wishes than anybody on the planet. I mean, he walks on water when it comes to the WWE. And he was able to tell Vince, 'I'm not [going to Saudi Arabia].' I don't think they're ever going to let anybody get to that level again where they have control or say."

WWE invested in Roman Reigns, and wanted him to take over the stardom. He took part in the main-event of WrestleMania four times in a row, but was sadly diagnosed with leukemia. He is now on an indefinite break from WWE in order to get better, which left WWE without its biggest star. Hopefully, the void will get filled, as many popular wrestlers remain with Seth Rollins, Elias, Finn Balor and Braun Strowman.
The question still remains. Can any of these guys become as widely recognizable and famous as the legends of old, who went on to become even bigger stars in other entertainment business? Only time will tell.

Q: How to use input from a java code and transfer it into an external application (as well as retrieving output)? I'm actually not that great and am relatively new at Java. I wish to receive input from the user, and want to input this data into an external application.
This application processes the data and provides an output. I wish to retrieve this output using the Java code.
I have attempted in doing this but, I haven't got the slightest idea on how to start this script.
Nothin' on the internet seems to answer this question. If you have any idea or any new functions that can be useful, please help me in doing so.
Since I'm starting from ground zero, any help is appreciated.
Thanks so much.

A: To communicate with an external application you need to first define the communication way. For example:

*

*Will this application read the output from a file?

*

*If that statement it's true, then you need to learn serialization:

*Will this application read the input from the standard output (like a command-line application)

*

*If that statement it's true then you need to send with System.out.print().

*Will this application get the data over HTTP.

*

*Then you need to learn about REST and or RPC architectures.

Assuming that it will be a command-line application, then you could use something like this:
public class App
{
    public static void main(String... args)
    {
        // You need to implement your business logic here. Not just print whatever the user passes as arguments of the command-line.

       for(String arg : args)
       {
           System.out.print(arg);
       }
    }
}

A: There's a lot going on here but I'll suggest an example for each part of this question and assume this is just going to be written in Java, and suggesting an iterative design/development approach.

*

*receive input from the user::getting arguments from the command line can work, but I think most users want to use familiar user interfaces like excel to input large amounts of data. Have them export files to .csv or look into reading excel files directly with apache poi. The latter is not for beginners, but not terrible to figure out or find examples. The former should be easy to figure out if you look into reading files and splitting them line by line on the delimiter.  Here's an example of that:
try (BufferedReader reader = new BufferedReader(new FileReader(new File("user_input.csv"))) {
    String currentLine = reader.readLine();
    while (currentLine != null) {
        String splitLine[] = currentLine.split(","); //choose delimiter here
        //process cells as needed
        //write output somewhere so other program can read it later
        currentLine = reader.readLine();
    }
}
catch (IOException ex) {
    System.out.println(ex.getMessage()); //maybe write to an error log
    System.exit(1);
}

*"input" data to other app::you can use pipes if you're at the command line. but I'd recommend you write to a file and have the other app read it. here's an expansion of the previous code snippet showing how to write to a file as that might be more practical and easier to log/archive/debug.
try (BufferedReader reader = new BufferedReader(new FileReader(new File("user_input.csv")));
    BufferedWriter writer = new BufferedWriter(new FileWriter(new File("process_me.csv")))) {
    String currentLine = reader.readLine();
    while (currentLine != null) {
        String splitLine[] = currentLine.split(","); //choose delimiter here
        //process cells as needed
        writer.write(processed_stuff);
        currentLine = reader.readLine();
    }
}
catch (IOException ex) {
    System.err.println(ex.getMessage());
    System.exit(1);
}

*Then retrieving output::can just be reading another file with another Java program.  This way you're communicating between programs using the file system.  You must agree upon file formats and directories though.  And you'll be limited to having both programs on the same server.
To make this at scale, you could use web services assuming the other program you're making requests to is a web service or has one wrapped around it.  You can send your file and receive some response using URLConnection.  This is where things will get much more complex, but now everything in your new program is just one Java program and the other code can live on another server.
Building the app first with those "intermediate" files between the user input code, the external code, and the final code will help you focus on perfecting the business logic, then you can worry about just communication over the network.

The insects came at night hidden within some of my old friends. They searched our mouths and ears for the opening of the virtual communication cluster. Blood was there, the core method for the transformation of our species. Ready for the taking. The entrance was placed in the implantable cell phones we had all adopted. An energy source was not needed. Intimacy, attention, security, containment. All empty forms full of fire. They came at night through brain-to-brain internet communication. They came with heavy metallic instruments And thick boots made of light. They came at night, as a furious adaptation to the isolation of the social, carrying sparkling weapons of sound. They scattered their seeds and diversified, such thick waisted pleasure seekers and their young attendants in the fields. One opening, one door That is all they sought. We never actually met in the flesh. Telepathy would undoubtedly increase with their coming, but the clouds were heavy and the invisible steps led so much higher. Nature is conservative after all. Always disguised by the most simple of obstacles. One needs eyes to see.
Just beautiful.. nearly put me to sleep. [ I mean that in a positive way of course ]. Thank you, I needed to relax and this did it.

Mother of Boko Haram leader, Abubakar Shekau, speaks
Falmata Abubakar the mother of Abubakar Shekau, the leader of
Boko Haram, granted her first media interview to VOA, saying she
has not seen her son in 15 years. .
The interview took placein the village of Shekau, Yobe state. The
report published by VOA revealed that Mr Shekau's late father was
the Imam of the village Mosque before his death.
Ms Abubakar said she had no idea where her son was or his
situation. "I don't know whether he is dead or alive, only God
knows, I have not seen him in the last 15 years," she said.
She said Mr Shekau left the village for Maiduguri, the Borno state
capital as a young boy in search of Islamic knowledge. She said he
was an "almajiri boy" who walks around the streets of Maiduguri
looking for food. .
She said it was in the course of seeking Islamic knowledge that her
son came into contact with the founder of Boko Haram,
Mohammed Yusuf. She said the late Boko Haram leader was the
one who indoctrinated her son.
"I did not set my eyes on him since he came into contact with
Mohammed Yusuf," she said. "I know he is my son, and everyone
knows a mother's love for her son, but our attitude to life is
different," she said.
She also said "He has put so many people in serious difficulty, I
pray that God guides him right". Ms Falmata said she will not
curse his son, saying "he has chosen a path different from the one
we put him on, only God knows what he has become now".
Mr Shekau took leadership of the group after the death of its
founder, Mr Yusuf, who was killed in police custody.

Armed Forces Remembrance Day: Oyetola lauds fallen heroes, valiant fighters on supreme sacrifice for nation building 15/01/2021 4:43 pm


Set in the wide sweep of St Ives Bay, 3 miles of golden sands, stretching from Porth Kidney Sands on the west side of the treacherous mouth of the River estuary, past Black Cliffs, along the Towans as far as Gwithian in the far west with the magnificent backdrop of Godrevy Lighthouse. Gwithian Sands attracts the extreme sports fraternity:-kite surfers, land sailing, blokarts and speedsails. A zoning system is being trialled banning all wind powered activities as well as horse riding from the parts of the beach most popular with families in the summer months. Lifeguards operate in season keeping a watch over the bathing areas. It can not be stressed on no account should you swim between the Red River and Godrevy Point given the dangerous currents as the tides sweeps twice daily through the narrow channel between the Point and the Lighthouse, or at the mouth of the Hayle River. Surfing Holiday Cornwall-in season wet suits and boards are for hire from the Car park by the Sunset cafe. Surf tuition is available from professional instructors at the local surf academy.
Godrevy Lighthouse with its distinctive white octagonal tower was erected in 1859, and automated in 1939. Did you know it was the inspiration for Virginia Woolfe's novel "To The Lighthouse"? Can you see the now disused former keepers stone cottages to the left of the lighthouse?
Walk west along the Cornish Coast around the grassy headland toward Portreath along some of the highest cliffs in Cornwall, with names such as Hells Mouth. Seals sometimes seen under Navax Point though elusive and preferring rough seas. Keep back from cliff edges at all times. Beware of the rip tides.
Behind the towans (Cornish for sand dunes) are several Cornwall Hayle Holiday Parks, the perfect place for a self catering beach holiday in a chalet, bungalow, lodge or caravan.
Hayle A hundred and fifty years ago the town was at the summit of its industrial glory. Harvey's massive foundry complex dominated, producing steam engines for use not only in Cornwall's mines, but also mines the World over. Just north of the town was Wheal Alfred Consols, producing tin and later in its working life copper. The mine is well known by mineral collectors for fine specimens of pyromorphite.
The port served the Central Mining Belt exporting copper ore to the smelters in Wales, importing timber props and coal for the mine engines. What is now an important wildlife habitat, Carnsew Pool, was constructed at this time, the sluices were opened to keep the treacherous harbour entrance free of sand. Indeed older locals can remember back to the 1950's when the harbour was still a bustling place the sluices were still in regular use and the channel dredged. Hundreds of people were still employed by 'The Docks', with imports of coal and timber, exports of scrap metal.
Warnings. Hayle Bay can be treacherous and should only be navigated by experienced skippers. The Hayle River, the River mouth and the open sea beyond the Red River toward Godrevy Point are notorious for their rip currents and undertows. On no account should you enter the water in those areas. Hayle Towans and Gwithian Towans beaches are popular with visitors, with lifeguards in Season. Good Beach Guide.
The upper reaches of the Hayle Estuary (the most south-westerly estuary) in the UK are a good place to watch birds in autumn and winter. Wading birds such as dunlins, curlews and grey plovers spend the winter here as do often thousands of migrants, from widgeon, to teals and shelducks blown west by cold easterly winds. Little Egret are resident and you may be lucky to see one of these so beautiful birds.

Weather affects everything. It is both an essential resource and a significant risk factor for life on Earth. What's more, the weather is one of the most unpredictable aspects of human existence, yet we have no choice but to try our hand at predicting it. After all, our very lives depend on our having ample supplies of foodstuffs that are themselves dependent on adequate precipitation, growing seasons and so forth. Weather is no small matter. Many businesses are directly or indirectly linked with weather conditions. For instance, agriculture relies on perfect weather forecasting for when to plant, irrigate and harvest.
Insurance is one way to increase resilience to climate shocks, but not only in the way you might think. There's a subtler benefit to agriculture insurance, and one that is essential for adapting our food systems to a changing climate: when farmers feel financially secure, they're more likely to take productive risks. In the decades to come, we can expect increasingly difficult growing seasons for farmers, and so taking advantage of good years will become more and more important – for both our food supply and farmers' livelihoods. In recent years, agricultural insurance has become part research Actuarial Science program, particularly weather index-based insurance (WII). The interesting aspect has been that, rather than compensating observed damage, compensation in WII is determined on the basis of an independent index (such as the cumulative precipitation falling in a certain window of time or the average yield over a district).
Index insurance is innovative, but can it reach a critical mass using Satellite data provided by TWIGA?
Transforming Weather Information Growth In Africa - TWIGA is a 4-year project (2018 - 2021) under EU Horizon2020 aimed to transform weather water data into value-added information services.
Satellite data provide by TWIGA will give index insurance the scaling power needed to reach all the small scale farmers across Africa. A Kenyan Insurance sector stakeholders workshop will be held this first quarter of 2019 to address the challenges available in implementing weather-indexed based insurance. The theme of the workshop will be: Index insurance is innovative, but can it reach a critical mass using Satellite data provided by TWIGA? This could be the start of touching the livelihoods of millions of smallholder farmers across the African continent that are under threat from extreme weather events, such as droughts and floods with risks projected to increase significantly in future years due to climate change.
Developers require the ability to easily combine weather functionality, including forecast and observational data, with numerous data and application services to build advanced web and mobile applications that leverage cognitive capabilities, analytics, mobile, and IoT services without wasting cycles installing or managing software and deploying hardware.

The last two days I've discussed who should be selected as starters for both the National Leauge and the American League. Now I'm going to close the loop on this subject by giving you what I think should be the complete rosters for each team. Then I'll be done discussing the rosters for the All Star Game (finally). I have followed the rules for roster construction, so each team is represented and there are 32 players per team.
Jon Rauch was the only selection that was a bit of a stretch so that all teams were represented, but he's had a pretty decent half season as closer for the Nationals. Aaron Cook is the only Colorado representative and there were other pitchers that were probably more deserving, but his selection isn't a huge stretch. Notable snubs on my selected team include Mark Teixeira, David Wright, Carlos Zambrano, Ryan Dempster, Tim Hudson, Cole Hamels, Kyle Lohse, Chad Billingsly.
The American League was easier (which makes sense with fewer teams) - there were no choices that were made solely to make sure each team is represented. Jermaine Dye was not on my list on Monday, which was an oversight on my part. Notable snubs include Nick Markakis, BJ Upton, Justin Morneau, David DeJesus, John Danks, Shawn Marcum, Dana Eveland, Greg Smith, Gavin Floyd, Matt Garza, Jon Lester.

Azure ML is Helping CMU Become More Energy Efficient
October 8, 2014 June 25, 2015 by ML Blog Team // 1 Comments
Posted by Vinod Anantharaman, head of business strategy, Microsoft Information Management and Machine Learning (IMML).
Buildings are powered by multiple systems such as heating, cooling, lighting, ventilation, security and more, each of which affect occupant comfort and energy consumption. Traditionally, each system comes with its own sensors, actuators and the like, and some of these may gather and analyze data specific to that particular system. Because of this silo-based approach to building management, there traditionally has not been a holistic, or dashboard view of the operational efficiency of a building. This has made it challenging to accurately predict energy use or waste.
Based in Pittsburgh, Pennsylvania, Carnegie Mellon University (CMU) is a leading research university with over 12,000 students and 5,000 faculty and staff, and a birthplace of innovation since its founding in 1900. At CMU, the Center for Building Performance and Diagnostics is responsible for developing hardware and software solutions that improve the efficiency of campus buildings while achieving higher occupant comfort.
CMU Center for Building Performance and Diagnostics ©Carnegie Mellon University. All rights reserved.
The Center saw an opportunity to create an integrated, automated system that could increase the energy performance of their buildings and deliver cost savings by predicting energy consumption patterns, detecting faults and taking actions in real-time. Such a system would anticipate heating and cooling needs and adjust thermostats accordingly, and it would alert building managers to repair or replace worn-out parts before they failed altogether.
In pulling together such a predictive analytics system, two of CMU's primary requirements were:
It had to be easy to implement; and
It also had to be accessible to non-technical personnel.
Working in partnership with OSIsoft, the Center created an integrated system to harness all its historical and current sensor data using the power of predictive analytics. Azure Machine Learning is one of a few major components in the CMU solution, which begins with an on-premises PI Server™ that collects sensor data from across the campus, forwards it via Microsoft Azure -based PI Cloud Services™ to a PI Server running in Azure, where an OSIsoft research tool then cleanses, aggregates, shapes, and transmits the data in real-time to an Azure repository, where it is accessed by Azure ML for predictive analytics. The predictive insights are then made accessible through Power BI, with predictions being stored in the PI Server for use by the building systems applications.
The solution was fast, easy, and inexpensive to set up and use. "We immediately began using Azure Machine Learning without having to prepare on-premises software; everything's ready-to-use in the cloud," says Bertrand Lasternas, a Researcher at the Center. "It's significantly easier to use than other tools we've tried, and it fit seamlessly with the PI System and Microsoft cloud solution we already had."
Here are a couple of illustrative use cases involving the CMU solution:
A specified building's temperature needs to be brought up to 72 degrees at the start of business at 9 a.m. The heating system is typically engaged at 6 a.m. or, on warmer days, at 6:30 a.m. But that likely wastes energy and CMU wanted to use predictive analytics to identify the ideal time to start heating the building. Researchers aimed to predict the internal temperature of the building at 9 a.m. using a model that included recent internal and external temperature, anticipated solar radiation levels, and several other factors. Since anticipated solar radiation data was not available, researchers first had to predict this variable. They trained a solar radiation model using a boosted decision tree algorithm in Azure ML, tested the model to confirm its accuracy, and then used it in the internal temperature model to address the question of when to start the heating, resulting in predicted energy savings.
CMU also wanted to address the challenge of fault detection and diagnosis for components that are hidden from visual inspection because they are behind walls or under floors. By using Azure ML on the historical data gathered by the PI System, they are able to predict such faults, resulting in potential cost savings.
The Azure ML solution also fosters collaboration by allowing teams of researchers or graduate students to share workspaces with each other.
Based on the experimental results, CMU researchers estimate their solution can cut energy costs by 20 percent. Discussions are underway to implement it campus-wide, where it could save several hundreds of thousands of dollars annually. "The savings come both from reducing energy use and from being able to shift some energy use to hours of lower demand and cost," says Lasternas.
The CMU researchers envision the PI System and Microsoft Azure supporting not just researchers but also the engineers and technicians who interact daily with building systems. For example, field service technicians could access the insights from predictive analytics on their tablets to check and update remote equipment before it fails. Smartphone notifications could alert engineers to energy demand spikes. Because the solution is scalable and cost-effective, it could be used at building complexes and public-utility systems that cannot be served by traditional solutions.
Customers across a swathe of industries are deploying enterprise-grade predictive analytics solutions using Microsoft Azure ML – you too can get started today.
At CMU, they are anticipating broad new uses for the solution they have built. "We see Azure Machine Learning and the PI System ushering in an era of self-service predictive analytics for the masses," says Lasternas. "We can only imagine the possibilities."

The declaration by Sweden's former prime minister Fredrik Reinfeldt that "there is plenty of space for more refugees" in the Nordic countries was rejected out of hand by Danish leaders.
In an interview with Politiken over the weekend, former Swedish PM Fredrik Reinfeldt criticised the Danish government's plans to make resident permits for refugees temporary, saying that there is plenty of room in the Nordic countries to permanently house people fleeing oppression and war.
"What does the word 'enough' mean? Is Sweden full? Is the Nordic region full? Are we too many people? We are 25 million people living in the North. I often fly over the Swedish countryside and I would advise others to do. There are endless fields and forests. There's more space than you might imagine. Those who claim that the country is full, they should demonstrate where it is full," the former Swedish leader said.
But Reinfeldt shouldn't expect Danish politicians to jump on board with his plan to welcome more refugees to the region.
"This is the first time I've heard that a country's geographic size should determine how many people from distant lands can be fit in. That's a new one for me. But space is not the problem – the problem is that we have huge economic and cultural challenges," Martin Geertsen, the integration spokesman for opposition party Venstre, told BT.
Mette Reissmann of the ruling Social Democrats summarily dismissed Reinfeldt's criticism.
Denmark's plans to make asylum temporary for Syrian refugees and to limit their ability to bring family members to the country under family reunification have been criticised by the United Nations Refugee Agency and a long line of human rights organisations.
Reinfeldt's successor as Sweden's prime minister, Stefan Löfven, was forced to call a snap election just three months into his term. In his interview with Politiken, Reinfeldt also said that "there is no place" for the anti-immigration Sweden Democrats.

Hugh D Bryant
Reader (Licensed Lay Minister) in the Church of England;
former Solicitor and Marine Underwriter
Roger McCormick and his colleagues in what is to become the 'CCP Foundation' have produced research which shows that fines and damages paid and estimated for misconduct, in the 10 banks which they have studied, in the last 5 years have amounted to £157 billion worldwide. In the UK alone this amounts, on average, to nearly £6 billion per annum.
These figures are now being analysed further to identify whether any of the banks under review are improving their performance: and to identify criteria by which performance in this area can be compared, across different countries, markets and types of bank.
It is however clear that conduct costs, or rather the cost of misconduct, are a very significant impost on the cost of trade and the efficiency of the banking system, and are therefore, as a matter of public policy, a mischief which urgently calls for a remedy. Indeed even the bankers themselves recognise that there is an urgent need for public trust in their activities to be restored.
Given that such misconduct is clearly a bad thing, how is it to be stopped? McCormick tells a story to bankers and others at his seminars. Imagine you are on one side of a transaction, and you notice that your counterparty has made a serious mistake, which they have not noticed. The result of the mistake is that you will do much better out of the transaction than you would have done if the other side had not made their mistake.
What do you do? Keep silent and pocket the profit, or point out the mistake – and get what you would reasonably have expected to get out of the transaction, but no more.
Today, McCormick has said, many of those, to whom he puts the story, find it difficult to answer. It might be thought that their chief objective is to make money, to maximise profit. It is not part of their objective to do this in an ethical way. Instead, their only thought of ethical considerations is whether they will, by acting in a particular way, lay themselves open to regulatory sanction. The criterion is not whether it is bad to do something, but whether a policeman will catch me if I do it.
But regulators, almost by definition, offer no solution: we are, after all, trying to reduce the amount of fines and penalties. If we simply say that regulators should regulate less strictly, it would reduce the fines, but it would not necessarily improve the conduct. (We can observe in passing that in identifying the mischief which is banking misconduct, we have defined it by the amount it costs rather than by its moral badness – but it nevertheless remains a serious mischief.)
What is to be done? Lawyers will be familiar with the alleged antithesis between what is lawful, and what is morally right. The existence of that antithesis is, it could be said, a major factor in facilitating banking misconduct. It might look as though bankers' conduct is determined not by any consideration whether something is morally right, but rather whether it is legally permitted – or whether, even if it is unlawful, whether there is a risk of being caught out by a regulator.
It seems that the only way to obviate conduct costs entirely is to improve conduct – morally. If it were true that a course of action needed to be both lawful and morally right, this would leave no room for moral arbitrage of the kind which McCormick's story brings out.
How can this be brought about? I suggest that, as well as experts in the upholding of professional standards – such as members of the International Accounting Standards Committee, say – it would be helpful to invite the Archbishop of Canterbury, Justin Welby, to widen the scope of his activity, for example in the St Paul's Institute, so as to include advice to and involvement with the Conduct Costs Project.

Q: Number of connected components of a given curve inside a particular set Assume that $(X,d)$ is a metric space and let $\Omega\subset X$ be a open set with $\operatorname{int}(\overline{\Omega})=\Omega$.
Let $\alpha :[0,1]\to X$ be a Lipschitz curve and consider the two sets $\overline{\Omega}\cap\alpha([0,1])=U_1$ and $(X\setminus\Omega)\cap\alpha([0,1])=U_2$.
I am trying to prove (maybe it is not true) that the number of connected components of $U_1$ and $U_2$ is finite. Any idea is aprreciated.

A: Consider $X = \mathbb{R}^2$ with the usual metric. Set $\alpha(t) = (t, 0)$.
Now let $\Omega$ be the area under the graph of $x \sin(\frac{1}{x})$. That's a continuous function, so $\Omega$ is an open set and the function is its boundary.
It should be easy to see both $\overline{\Omega}\cap\alpha([0,1])$ and $(X\setminus\Omega)\cap\alpha([0,1])$ contain countably infinite number of connected components.


Materials provided. All welcome. Under 12's must be accompanied by an adult. No charge but donations would be appreciated. On Sunday 19th 12pm-3pm the Community Room below the Library will be open for those with mobility problems.


He is a former member of the Hezb-e-Islami party of ethnic Pashtun former jihadi commander, Gulbuddin Hekmatyar.
Imam Sahib (Kunduz) is dominated by the Ibrahimis, an Uzbek clan, which rose from nothing to become the predominant family of that district and beyond in the course of war. Imam Sahib is situated on the border with Tajikistan. It is a fertile agrarian district and moreover a key hub for the drugs trade. Accordingly, both the district itself and the post of the chief of the border police are strategically very significant. Abdul Latif Imbrahimis brother, Haji Raoof, earned a reputation as a commander, headed the border police Kunduz in Imam Sahib and won a seat in the parliamentary elections 2005. Finally, the locally strategically important position of the »mirab bashi,« who controls farmers' access to the important resource of water, is monopolized in the hands of Afiz, the brother-in-law of Haji Raoof, whereas in other districts this position is commonly exercised by members of different clans and usually varies from irrigation canal to irrigation canal. Thus the Ibrahimis rule the district in a quasi-feudalistic way and control access to economic resources. Hence, most small warlords in Imam Sahib are directly dependent on this family. While the means of force in Imam Sahib are monopolized by one family. Khanabad provides a different picture. During the war the district was under the control of Commander Amir, the most influential commander of the Islamist Abdulrab Sayyaf in north-eastern Afghanistan. After Amir's death, he was followed by his brother Ghulam, who lost several of his sub-commanders due to the upsurge of ethnic and political polarization since the collapse of the Taliban. Taken together with the lack of commonly shared institutions, this led to a fragmentation of violence and the emergence of a myriad of loosely connected small »big men«, rarely controlling more than one village. Their actions are restricted solely by competition with other »big men,« but not controlled or regulated by the local population or the government.

Q: How to sort an array in descending order in Ruby I have an array of hashes:
[
  { :foo => 'foo', :bar => 2 },
  { :foo => 'foo', :bar => 3 },
  { :foo => 'foo', :bar => 5 },
]

I am trying to sort this array in descending order according to the value of :bar in each hash.
I am using sort_by to sort above array:
a.sort_by { |h| h[:bar] }

However, this sorts the array in ascending order. How do I make it sort in descending order?
One solution was to do following:
a.sort_by { |h| -h[:bar] }

But that negative sign does not seem appropriate.

A: What about:
 a.sort {|x,y| y[:bar]<=>x[:bar]}

It works!!
irb
>> a = [
?>   { :foo => 'foo', :bar => 2 },
?>   { :foo => 'foo', :bar => 3 },
?>   { :foo => 'foo', :bar => 5 },
?> ]
=> [{:bar=>2, :foo=>"foo"}, {:bar=>3, :foo=>"foo"}, {:bar=>5, :foo=>"foo"}]

>>  a.sort {|x,y| y[:bar]<=>x[:bar]}
=> [{:bar=>5, :foo=>"foo"}, {:bar=>3, :foo=>"foo"}, {:bar=>2, :foo=>"foo"}]

A: It's always enlightening to do a benchmark on the various suggested answers. Here's what I found out:

#!/usr/bin/ruby

require 'benchmark'

ary = []
1000.times {
  ary << {:bar => rand(1000)}
}

n = 500
Benchmark.bm(20) do |x|
  x.report("sort")               { n.times { ary.sort{ |a,b| b[:bar] <=> a[:bar] } } }
  x.report("sort reverse")       { n.times { ary.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse } }
  x.report("sort_by -a[:bar]")   { n.times { ary.sort_by{ |a| -a[:bar] } } }
  x.report("sort_by a[:bar]*-1") { n.times { ary.sort_by{ |a| a[:bar]*-1 } } }
  x.report("sort_by.reverse!")   { n.times { ary.sort_by{ |a| a[:bar] }.reverse } }
end

                          user     system      total        real
sort                  3.960000   0.010000   3.970000 (  3.990886)
sort reverse          4.040000   0.000000   4.040000 (  4.038849)
sort_by -a[:bar]      0.690000   0.000000   0.690000 (  0.692080)
sort_by a[:bar]*-1    0.700000   0.000000   0.700000 (  0.699735)
sort_by.reverse!      0.650000   0.000000   0.650000 (  0.654447)

I think it's interesting that @Pablo's sort_by{...}.reverse! is fastest. Before running the test I thought it would be slower than "-a[:bar]" but negating the value turns out to take longer than it does to reverse the entire array in one pass. It's not much of a difference, but every little speed-up helps.

Please note that these results are different in Ruby 1.9

Here are results for Ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin10.8.0]:
                           user     system      total        real
sort                   1.340000   0.010000   1.350000 (  1.346331)
sort reverse           1.300000   0.000000   1.300000 (  1.310446)
sort_by -a[:bar]       0.430000   0.000000   0.430000 (  0.429606)
sort_by a[:bar]*-1     0.420000   0.000000   0.420000 (  0.414383)
sort_by.reverse!       0.400000   0.000000   0.400000 (  0.401275)

These are on an old MacBook Pro. Newer, or faster machines, will have lower values, but the relative differences will remain.

Here's a bit updated version on newer hardware and the 2.1.1 version of Ruby:
#!/usr/bin/ruby

require 'benchmark'

puts "Running Ruby #{RUBY_VERSION}"

ary = []
1000.times {

}

n = 500

puts "n=#{n}"
Benchmark.bm(20) do |x|
  x.report("sort")               { n.times { ary.dup.sort{ |a,b| b[:bar] <=> a[:bar] } } }
  x.report("sort reverse")       { n.times { ary.dup.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse } }
  x.report("sort_by -a[:bar]")   { n.times { ary.dup.sort_by{ |a| -a[:bar] } } }
  x.report("sort_by a[:bar]*-1") { n.times { ary.dup.sort_by{ |a| a[:bar]*-1 } } }
  x.report("sort_by.reverse")    { n.times { ary.dup.sort_by{ |a| a[:bar] }.reverse } }
  x.report("sort_by.reverse!")   { n.times { ary.dup.sort_by{ |a| a[:bar] }.reverse! } }
end

...the reverse method doesn't actually return a reversed array - it returns an enumerator that just starts at the end and works backwards.

The source for Array#reverse is:
               static VALUE
rb_ary_reverse_m(VALUE ary)
{
    long len = RARRAY_LEN(ary);
    VALUE dup = rb_ary_new2(len);

    if (len > 0) {
        const VALUE *p1 = RARRAY_CONST_PTR_TRANSIENT(ary);
        VALUE *p2 = (VALUE *)RARRAY_CONST_PTR_TRANSIENT(dup) + len - 1;
        do *p2-- = *p1++; while (--len > 0);
    }
    ARY_SET_LEN(dup, RARRAY_LEN(ary));
    return dup;
}

do *p2-- = *p1++; while (--len > 0); is copying the pointers to the elements in reverse order if I remember my C correctly, so the array is reversed.

A: You could do:
a.sort{|a,b| b[:bar] <=> a[:bar]}

A: Regarding the benchmark suite mentioned, these results also hold for sorted arrays.
sort_by/reverse it is:
# foo.rb
require 'benchmark'

NUM_RUNS = 1000

# arr = []
arr1 = 3000.times.map { { num: rand(1000) } }
arr2 = 3000.times.map { |n| { num: n } }.reverse

Benchmark.bm(20) do |x|
  { 'randomized'     => arr1,
    'sorted'         => arr2 }.each do |label, arr|
    puts '---------------------------------------------------'
    puts label

    x.report('sort_by / reverse') {
      NUM_RUNS.times { arr.sort_by { |h| h[:num] }.reverse }
    }
    x.report('sort_by -') {
      NUM_RUNS.times { arr.sort_by { |h| -h[:num] } }
    }
  end
end

And the results:
$: ruby foo.rb
                           user     system      total        real

A: For those folks who like to measure speed in IPS ;)
require 'benchmark/ips'

ary = []
1000.times {
  ary << {:bar => rand(1000)}
}

Benchmark.ips do |x|
  x.report("sort")               { ary.sort{ |a,b| b[:bar] <=> a[:bar] } }
  x.report("sort reverse")       { ary.sort{ |a,b| a[:bar] <=> b[:bar] }.reverse }
  x.report("sort_by -a[:bar]")   { ary.sort_by{ |a| -a[:bar] } }
  x.report("sort_by a[:bar]*-1") { ary.sort_by{ |a| a[:bar]*-1 } }
  x.report("sort_by.reverse!")   { ary.sort_by{ |a| a[:bar] }.reverse }
  x.compare!
end

A: Simple Solution from ascending to descending and vice versa is:
STRINGS
str = ['ravi', 'aravind', 'joker', 'poker']
asc_string = str.sort # => ["aravind", "joker", "poker", "ravi"]
asc_string.reverse # => ["ravi", "poker", "joker", "aravind"]

DIGITS
digit = [234,45,1,5,78,45,34,9]
asc_digit = digit.sort # => [1, 5, 9, 34, 45, 45, 78, 234]
asc_digit.reverse # => [234, 78, 45, 45, 34, 9, 5, 1]

A: I see that we have (beside others) basically two options:
a.sort_by { |h| -h[:bar] }

and
a.sort_by { |h| h[:bar] }.reverse

While both ways give you the same result when your sorting key is unique, keep in mind that the reverse way will reverse the order of keys that are equal.
Example:
a = [{foo: 1, bar: 1},{foo: 2,bar: 1}]
a.sort_by {|h| -h[:bar]}
 => [{:foo=>1, :bar=>1}, {:foo=>2, :bar=>1}]
a.sort_by {|h| h[:bar]}.reverse
 => [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]

While you often don't need to care about this, sometimes you do. To avoid such behavior you could introduce a second sorting key (that for sure needs to be unique at least for all items that have the same sorting key):
a.sort_by {|h| [-h[:bar],-h[:foo]]}
 => [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]
a.sort_by {|h| [h[:bar],h[:foo]]}.reverse
 => [{:foo=>2, :bar=>1}, {:foo=>1, :bar=>1}]

A: Just a quick thing, that denotes the intent of descending order.
descending = -1
a.sort_by { |h| h[:bar] * descending }

(Will think of a better way in the mean time) ;)

a.sort_by { |h| h[:bar] }.reverse!
