![]() So next time you encounter a problem where you want to use a Stack, remember not to use the Stack class directly but a Deque. ![]() The iterator also returns elements in the order from first (head) to last (tail). This interface should be used in preference to the legacy Stack class.Īnother consistency it brings along is that there is no random element access. In fact the official java documentation recommends this interface over the legacy Stack class. It can be serve as a LIFO (last in first out) based collection, also referred to as a Stack. It is short for “double ended queue” and is we usually pronounce it as “deck”. Stack exists as a Class and not an Interface in Java and Kotlin.īoth Java and Kotlin offer an interface called Deque.Iterator of the stack follows FIFO strategy and not LIFO strategy.Stacks allow random access to the elements.This can bite you at some point of time in future, should you feel a need to move away from it.īefore moving further, let’s quickly recall the problems with the Stack class in Java and Kotlin. This means that if you use it in your code, you are committing to the implementation itself. Unlike most of the collections including but not limited to Lists, Maps and Queues, Stack is not an interface. If you are interested in the bug ticket, here it is. We sympathize with the submitter but cannot fix this because of compatibility. It was an incorrect design decision to have Stack extend Vector (“is-a” rather than “has-a”). However, it was closed with the following comment: This is the reason why we have random access in the Java and Kotlin Stacks and a FIFO strategy based iterator.Īlso, this is not something new but a very old bug, which was actually reported back in 2001. ![]() The decision was to extend Stack class with Vector class. Just like we do, they also made a bad design decision. Java like any other language was written by human engineers. Even though your intuition would tell you otherwise, Java and Kotlin would print the elements in the FIFO (first in first out) order. Our method should return “ dlrow olleh“.Ĭan you say which of the two following outputs, would this execution produce? Imagine we get “ hello world” as the input. Now to keep the example simple to follow, let’s say we want to reverse a string. Now there are many more creative applications of stacks in real life but for the scope of this blog these should suffice. To validate if a parenthesis is opening and closing correctly, a Stack is pretty handy. You can use a stack to backtrack the path if you hit a wall. If you are solving a problem to find a path in a maze. Syntax ParsingĬompilers use a stack to parse the syntax of expressions in the source code. Further, you can also convert from one type of expression to another using a stack. We use stacks to evaluate infix, postfix and prefix expressions. Where are Stacks used? Expression Evaluation & Conversion Next, let’s look at some common applications of stacks in real life. pop, which allows you to remove an element from the top of the collection.īased on this information, we can say that it follows a LIFO (last in first out) strategy.push, which allows you to add an element to the collection, and.In computer science, a Stack refers to a data structure for maintaining a collection of elements and it majorly supports these two operations: I promise you that by the end of this blog I will convince you to never touch the Stack class in Java/Kotlin even with a ten-foot poll.īefore we dive right in, let’s brush up our memory real quick so that we can enjoy the rest of the show. Whether you are a seasoned Java and/or Kotlin developer or are just beginning to test the waters. Let's take a closer look at them through examples.This is a story about me accidentally crossing paths with the Stack API in Java and Kotlin. However, what's interesting is that if we push the same elements in the same order into a Stack object and a Deque instance, their iteration orders are different. Since both Stack and Deque are subtypes of the interface, they are also Iterable. So, if thread-safety is not a requirement, a Deque can bring us better performance than a Stack.

![]() ![]() The ice needs to near-freeze all the liquid and the ice needs to break up in the shaker. To get a very frothy top on top of your espresso martini, you need to shake, shake, shake the mixture for a few seconds past when you think your arms will fall off (minimum 20 seconds). 4 Pro Tips for Perfect Frothy Foam on your Espresso Martini By the way, the time it takes to make this coffee cocktail in the recipe card below does not include making the espresso or coffee. Also fyi, using coffee will not give you a foamy top unless you use pro tip #4 below. If you’re going to make coffee especially for this cocktail, make it extra strong. If you are making your espresso martini at home and you don’t have espresso or an espresso machine, and you're not trying to impress anybody, just use coffee. Can I make an Espresso Martini with Coffee? But if you want a nice foam on top, there are a four tips below to make you look like a pro. If you shook long enough, you will have a nice froth on top to hold 3 coffee beans as a garnish. Shake it and strain it into a martini glass. In a cocktail shaker with ice, you put in vanilla vodka (regular vodka is okay if you don't have vanilla vodka), coffee liquor (Kahlúa), creme de cacao, and a shot of espresso. Making an espresso martini is fairly easy. So, it’s a fairly easy recipe that you can definitely make yourself at home. The recipe isn’t anything too special as far as creamy espresso martinis go, but I think Danny and Bojan made it look special by the glass they put it in, and the amount of foam that was on top from them shaking it up so long. When we got home to Miami, we sent a DM to one of the bartenders to get their recipe, and I’m now sharing it with you. Of course our joke the next few nights was to sit at the bar and order 23 espresso martinis. We watched as all three bartenders hustled to make them, and I can’t say it was done with a smile. Twenty minutes later, they ordered 23 espresso martinis (no lie, no exaggeration). The girls loved the cocktails and started telling all their coworkers about them. ![]() The next night when we were at the bar, a guy came up and ordered 3 espresso martinis for him and two girls he was with from the large convention group that checked into the hotel that afternoon. When he had some free time, he made us one. He said an espresso martini because there’s the extra step of brewing the espresso and waiting for it, so the total drink takes a long time, and they get backed up on making other drinks. One night we asked Danny what drink bartenders hated making the most. Last year we were in Grand Cayman and had a wonderful time, part of which was sitting at the Anchor & Den Bar where we met two of the bartenders, Danny and Bojan. 23 Espresso Martinis & 3 Unhappy Bartenders If you are out on the town with friends, just don’t ask the bartender to make 23 of them. If made perfectly, there’s nice creamy foam on top where you put a few espresso beans as a garnish. A frothy espresso martini is the perfect drink to get your night started, or something to brighten your eyes half-way through your night. What do you do when you want to have a cocktail, and you need a little pick-me-up at the same time? You have an espresso martini of course.

![]() "I thought it was very disrespectful, to be honest with you." "You saw the incident that happened in La Liga and of course you've seen the punishment, which is very, very unfortunate," Webb told a select group of journalists at a meeting in midtown Manhattan on Tuesday. Webb singled out the Spanish football federation for criticism after it fined La Liga club Villarreal 12,000 euros ($16,500) after a fan threw a banana at Barcelona's Dani Alves. Jeffrey Webb, the chairman of FIFA's Anti-Racism and Discrimination Task Force, said that while the world and regional bodies had introduced strict new laws to combat racism, some national leagues were ignoring the proposals and being too lenient. We work to be 100 percent for all games and you have some matches better than others but tomorrow we will be at a high level."įIFA's anti-racism chief Jeffrey Webb has called on national soccer associations to start implementing tougher sanctions to rid the game of discrimination, describing the use of monetary fines as ‘disrespectful’ and little more than a 'slap on the wrist.' "We are all 100 percent," he told the news conference.

Sevilla coach Unai Emery admits that Benfica are favourites to win the Europa League final on Wednesday but says his side will stay faithful to their style of play and believe in their chances. Issues with his knee sidelined him for long spells over the last two years. "I didn't cry about it yesterday, and I'm not crying about it today, that means I'm leaving with no regrets," he told a news conference at the Park Ji-sung Football Centre in Suwon, where he has a street named after him.Īfter leaving Manchester United in 2012, Park signed for Queen's Park Rangers but spent the last season on loan at PSV. The 33-year-old, who called time on his international career after the 2011 Asian Cup, said he could not continue to play at the highest level because of knee issues but added that he was leaving the game without any regrets. ![]() Park's industry, energy and work ethic made him a favourite of Alex Ferguson during his time at Manchester United and his performances in England and in the Netherlands with PSV Eindhoven helped raise the profile of Korean soccer around the world.

"We had some hard moments in the dressing room but we never argued with the manager or his assistants. It hurts but we could say those things to each other because we have been together for so long. When you have bad times, people show they care. But everyone lost belief in the team," the 32-year-old Serb said. It was a bad time and the players could have done better. "I am not saying we have had a good season. Vidic, who is set to join Inter Milan after playing the last of his 300 games for United against Southampton on Sunday, said there were no dressing-room fallouts with Moyes and the only arguments were between players desperate to improve. Moyes was sacked in April, only 10 months into a six-year contract, after United failed to qualify for the Champions League for the first time since 1995/96. That shows the players have respect for the manager." "From the first day until the last you didn't hear any player say anything bad about the training. "Sometimes you do things well, sometimes you don't. "They did everything that was asked of them. "There is no question over any of the players," Vidic told the BBC. Departing Manchester United captain Nemanja Vidic has denied the players failed to give their all for former manager David Moyes. If you must take both, take them at least two hours apart.” “Zinc can help to boost the immune system but can interfere with your body’s absorption of copper. If you are taking copper supplements because of copper deficiency, avoid taking zinc at the same time, says Dr. Tripathy, because they have blood-thinning potential and “taking both together can increase risk for uncontrollable bleeding or inability to clot.” Copper and zinc Both can be helpful supplements to take, but not at the same time, according to Dr. Omega-3 fish oil supplements are great for heart health and gingko biloba has cognitive benefits, according to studies. Airey says it’s “simply not efficient” to take them together, as your body’s ability to absorb the vitamins will be reduced if you take them all at the same time. These vitamins won’t produce harmful interactions, but Dr. “It’s advised that you take these vitamins at least 2 hours apart to maximize your absorption.” “Studies have shown that a person’s absorption of Vitamin K may be reduced when other fat-soluble vitamins such as Vitamin E and Vitamin D are taken together,” Chris Airey, a GMC-registered doctor in the UK and medical director at Optimale, tells SheKnows. In order to maximize the benefits, make sure to take them two hours apart. However, both magnesium and calcium may be helpful supplements to take separately because they can help prevent osteoporosis, Jaydeep Tripathy, a senior resident in the Department of Radiology at Kamakshi Hospital, tells SheKnows. Additionally, she says to refrain from taking calcium, magnesium, or zinc together as they will “compete for absorption.” But if you do take magnesium, Erin Stokes, naturopathic doctor and medical director at MegaFood, recommends not taking it at the same time as your multivitamin, as it may interfere with the absorption of smaller minerals found in the multivitamin, like iron and zinc. Many people like to take magnesium in the evening, as it can promote a sense of calm and supports muscle relaxation. With that said, keep reading to learn about some common supplements you shouldn’t take together. It’s also important to note that you should always talk to your doctor before starting a new supplement (even if it’s “just” a daily multivitamin!), and make sure to read the information packet on any new prescription you receive - it should list out any supplements that trigger adverse interactions with the medicine. Plus, taking some supplements concurrently may result in adverse interactions, which can be harmful to your health. ![]() In some cases, the amount of a vitamin your body is able to absorb depends on which other supplements you might be taking at the same time. ![]() One reason behind the confusion? Some supplements simply don’t play nice together. ![]() However,the West African Black rhinoceros was not the only species to go extinct in 2011. Though scientists do not know much how rhinos fit in the food chain,they do know that rhinos help maintain grasslands. ![]() If the entire rhino species went extinct,an entire community could be thrown apart. The extinction of West African Black rhinos only affected the environment a little but if more species of rhinos go extinct it could be catastrophic and seriously affect the environment. Also,it would take experts to handle the rhinoceros and not make them try to fight. It would have been simply too hard to catch all the West African Black rhinoceros and move them to Cameroon. However this experiment was not attempted as it required mammoth sums of money,and there was a huge probability that it would result in failure. In 1999 WWF recommended in a report to move all the remaining surviving West African Black rhinos to Cameroon which would allow people to monitor them and reduce the chances of poachers trying to attack drastically. People did try to increase the populations of the rhinos therefore to help decrease the risk of them going extinct. People also destroyed some habitats to build homes,and lots people killed large numbers of them just for entertainment. Farming destroyed many habitats of the West African Black rhinoceros,as farmers and ranchers saw them as pests due to them being such large herbivores. By 1980 there were only 135 western black rhinos left in 2 countries 25 in Chad and 110 in Cameroon. Between 19,an astonishing number of 98 percent of black rhinos were killed by poachers. The West African Black rhinos were targeted the most and it was clear. In the 1950s the leader of China told people to use traditional Chinese medicine instead of Western medicine,which increased the demand of rhino horns. In Chinese medicine rhino horns are widely used and are used for lots of medicines. Their horns fetched high prices and as a result poaching became common. Their horns which were used in Yemen and Oman for dagger handles,and in some parts of Asia for medicines,and are believed to contain properties that have anti-cancer. Like many animals it may have become extinct due to poaching. It once lived in Southern Africa and its last remaining habitat was in Cameroon where it was last seen 12 years ago in 2006. ![]() They were a subspecies of the black rhinoceros,and went extinct with 2 other species,which were the Southern Central Black rhino and the East African Black rhino. They would rather eat food which is better than eat more food which is worse. It was herbivorous and ate plants,branches,and fruit. In the meantime, we will continue to raise awareness about the fight against poaching.The diceros bicornis longipes,or better known as the West African Black rhinoceros or just the Western Black rhinoceros, were a species which lived not long ago. That's you, our readers! Endangered Wildlife Trust (EWT) and International Rhino Foundation (IRF) were the other two competitors on the "ballot." All three organizations are doing phenomenal work and we encourage you to learn more about them. On December 19th, we announced the winner, Save the Rhino - chosen by our online voters. To that end, we launched our first ever Rhino Donation Campaign and chose three outstanding wildlife conservation organizations to compete for the $10,000 prize. SafariBookings is committed to supporting wildlife conservation efforts and the fight against poaching. Black rhinos may look cumbersome, but they can run at up to 56kph, turn on the spot, and wield their horn with such dexterity that they can strike a tennis ball thrown towards them.Some 50% of males meet their end fighting. The black rhino has the highest known combat death rate for any mammal.Today, some 4,300 remain and the species is classed as Critically Endangered. This occurred mostly in China and the Middle East. Uncontrolled hunting was to blame – at first for trophies, and then to supply the lucrative market for its horn. Africa’s black rhino population plummeted from hundreds of thousands in 1900 to fewer than 2,500 by 2000.Three are now extinct and only three – the eastern, south-central and south-western – still have viable populations. Scientists have identified eight distinct regional subspecies of black rhino.The white rhino, by contrast, has a square mouth, which it uses for grazing. We also know this species as the ‘hook-lipped rhino’ from the prehensile upper lip with which it grips the woody plant stems on which it feeds.Both species acquire their colour from the mud in which they wallow, so vary from brown to grey.ĥ Fascinating Facts About the Black Rhino It is no more ‘black’, however, than its relative is white. We distinguish it from the larger white rhino by its shape, diet and temperament. The black rhino is the rarer and smaller of Africa’s two rhino species. ![]() The waitress roamed around a bit, then I ordered a tea and asked her whether I could get milk with it.

Thankfully, Jan did the right thing and comped the flying fish (do not order). I had one baked and the other grilled but both did not have enough salt. I ordered two fish, one recommended by the server and it was not good. I felt the food all around was just mediocre. And when you finish the courses the plates should be removed. The server apologized and said “I forgot.”When you order a bottle of wine, one should also not have to keep pouring your own wine. As the food was coming, I asked where is the wine. And when I ordered the bottle of wine, the server forgot to bring it over. For example, I dropped my paper napkin and the server said “let me get you a new one”, but never came back.
