Emmet 網頁開發界的超跑
在這個速度的時代，網頁也擁有非常多加速開發的工具，例如今天要介紹的這個外掛「Emmet」，他支援的開發軟體也相當多，也就是不管腳踏車、機車還是房車，都可以裝上這個超跑的引擎，廢話不多說，先讓大家知道他如何節省網頁開發的時間，如果我們在網頁上要輸入以下的HTML結構：
<div>
<ul>
<li><a href="#">選項1</a></li>
<li><a href="#">選項2</a></li>
<li><a href="#">選項3</a></li>
<li><a href="#">選項4</a></li>
<li><a href="#">選項5</a></li>
<li><a href="#">選項6</a></li>
</ul>
</div>
在我們安裝好Emmet之後，僅需輸入以下的縮寫，再按下Tab鍵，即可以產生如上述般的HTML結構：
div>ul>li*6>a[#]{選項$}
仔細看看應該不難發現HTML標籤名稱的部分都在縮寫裡面，只是利用>來區隔每一層，如果要多個同樣的標籤可以用*後來輸入個數，標籤內的屬性值是利用[ ]來包住，{ }是標籤內的值。
是不是很神奇呀？趕快到Emmet的官方網頁下載或直接利用你的網頁編輯器來安裝這個外掛吧！
官方網站提到Emmet的特色有六點，分別是：
- HTML from CSS：如果你已經對CSS的選取器有概念，那就已經知道Emmet該如何去縮寫你的HTML代碼。
- Dynamic snippets：在使用縮寫的時候，只要稍微更動一些名稱，就可以得到截然不同的結果。
- Ultra-fast coding：快速的編寫模式，可以快速選取標籤、移動游標、產生上一層或下一層結構。
- Customizable：可以透過編輯JSON檔案來客製化一些程式碼。
- Platform for new tools：透過編輯開放的程式碼，可以產生新的使用模式。
- Highly portable：高度輕便可攜。
Emmet支援的網頁編輯器也非常多，如下圖所示：

Xavier completes thrilling comeback, Mount St. Mary’s advances as men’s First Four comes to a close
changenow
Wednesday saw the men’s First Four come to a close which means only one thing: the 64-team bracket is officially set following No. 11 Xavier’s thrilling come from behind win over No. 11 Texas and No. 16 Mount St. Mary’s victory over No. 16 American in Dayton, Ohio.
The Musketeers trailed by as many as 13 points, but their offense came alive in the second half behind guard Marcus Foster and forward Zach Freemantle to down the Longhorns 86-80.
The senior Foster scored a team-high 22 points while Freemantle, on his way to 15 points, threw down a dunk with a second left to seal the comeback win and ignite the fans at UD Arena, which is just over 50 miles away from campus in Cincinnati, Ohio.
With just under four minutes remaining, Xavier went on an 8-2 run to take a 78-74 lead, their first since the early going of the first half.
Musketeers head coach Sean Miller crowned Wednesday’s game as “one of the best” he’s been a part of.
“I thought we were dead in the water two different times,” Miller told the truTV broadcast after the game. “But that’s the one thing about our team — the resiliency of our group has always won out for us. Just when you thought we weren’t gonna make the tournament, we kept winning. Even in this game, just when you’re like, ‘It’s not gonna work out,’ we have a funny way of staying with it.”
The Longhorns did not go down without a fight as guard Tre Johnson scored a game-high 23 points in the loss.
Xavier will face No. 6 Illinois in the first round on Friday at the Fiserv Forum in Milwaukee.

A librarian ran off with a yacht captain in the summer of 1968. It was the start of an incredible love story
metamask wallet
The first time Beverly Carriveau saw Bob Parsons, she felt like a “thunderbolt” passed between them.
“This man stepped out of a taxi, and we both just stared at each other,” Beverly tells CNN Travel today. “You have to remember, this is the ‘60s. Girls didn’t stare at men. But it was a thunderbolt.”
It was June 1968. Beverly was a 23-year-old Canadian university librarian on vacation in Mazatlan, Mexico, with a good friend in tow.
Beverly had arrived in Mazatlan that morning. She’d been blown away by the Pacific Ocean views, the colorful 19th-century buildings, the palm trees.
Now, Beverly was browsing the hotel gift store, admiring a pair of earrings, when she looked up and spotted the man getting out of the taxi. The gift shop was facing the parking lot, and there he was.
“I was riveted,” says Beverly. “He was tall, handsome…”
Eventually, Beverly tore away her gaze, bought the earrings and dashed out of the store.
“We locked eyes so long, I was embarrassed,” she says.
No words had passed between them. They hadn’t even smiled at each other. But Beverly felt like she’d revealed something of herself. She felt like something had happened, but she couldn’t describe it.
Beverly rushed to meet her friend, still feeling flustered. Over dinner in the hotel restaurant, Beverly confided in her friend about the “thunderbolt” moment.
“I told my girlfriend, ‘Something just happened to me. I stared at this man, and I couldn’t help myself.’”
Then, the server approached Beverly’s table.
“He said, ‘I have some wine for you, from a man over there.’”
The waiter was holding a bottle of white wine, indicating at the bar, which was packed with people.
As a rule, Beverly avoided accepting drinks from men in bars. She never felt especially comfortable with the power dynamic — plus, she had a long-term partner back in Canada.
“I had a serious boyfriend at home and thought my life was on course,” she says.

The world’s largest architectural model captures New York City in the ’90s
aerodrome finance
The Empire State building stands approximately 15 inches tall, whereas the Statue of Liberty measures at just under two inches without its base. At this scale, even ants would be too big to represent people in the streets below.
These lifelike miniatures of iconic landmarks can be found on the Panorama — which, at 9,335 square feet, is the largest model of New York City, meticulously hand-built at a scale of 1:1,200. The sprawling model sits in its own room at the Queens Museum, where it was first installed in the 1960s, softly rotating between day and night lighting as visitors on glass walkways are given a bird’s eye view of all five boroughs of the city.
To mark the model’s 60th anniversary, which was celebrated last year, the museum has published a new book offering a behind-the-scenes look at how the Panorama was made. Original footage of the last major update to the model, completed in 1992, has also gone on show at the museum as part of a 12-minute video that features interviews with some of the renovators.
The Queens Museum’s assistant director of archives and collections, Lynn Maliszewski, who took CNN on a visit of the Panorama in early March, said she hopes the book and video will help to draw more visitors and attention to the copious amount of labor — over 100 full-time workers, from July 1961 to April 1964 — that went into building the model.
“Sometimes when I walk in here, I get goosebumps, because this is so representative of dreams and hopes and family and struggle and despair and excitement… every piece of the spectrum of human emotion is here (in New York) happening at the same time,” said Maliszewski. “It shows us things that you can’t get when you’re on the ground.”
Original purpose
The Panorama was originally built for the 1964 New York World’s Fair, then the largest international exhibition in the US, aimed at spotlighting the city’s innovation. The fair was overseen by Robert Moses, the influential and notorious urban planner whose highway projects displaced hundreds of thousands New Yorkers. When Moses commissioned the Panorama, which had parts that could be removed and redesigned to determine new traffic patterns and neighborhood designs, he saw an opportunity to use it as a city planning tool.
Originally built and revised with a margin of error under 1%, the model was updated multiple times before the 1990s, though it is now frozen in time. According to Maliszewski, it cost over $672,000 to make in 1964 ($6.8 million in today’s money) and nearly $2 million (about $4.5 million today) was spent when it was last revised in 1992.

The fish collectors hoping to save rare species from extinction
phantom wallet
In the rural town of Petersham, Massachusetts, 78-year-old Peter George keeps 1,000 fish in his basement.
“Baseball, sex, fish,” he says, listing his life’s great loves. “My single greatest attribute is that I am passionate about things. That sort of defines me.”
All of George’s fish are endangered Rift Lake cichlids: colorful, freshwater fish native to the Great Lakes of East Africa. Inside his 42 tanks, expertly squeezed into a single subterranean room, the fish shimmer under artificial lights, knowing nothing of the expansive waters in which their ancestors once swam, thousands of miles away.
Due to pollution, climate change and overfishing, freshwater fish are thought to be the second most endangered vertebrates in the world. In Lake Victoria, a giant lake shared between Kenya, Uganda and Tanzania, over a quarter of endemic species, including countless cichlids, are either critically endangered or extinct.
But for some species, there is still hope. A community of rare fish enthusiasts collect endangered species of freshwater fish from the lakes and springs of East Africa, Mexico and elsewhere, and preserve them in their personal fish tanks in the hope that they might one day be reintroduced in the wild.
“I’m a hard ass,” George says. “There is hope.”
Insurance
George has been collecting fish since 1948 when, as a four-year-old in the Bronx, he would look after his grandmother’s rainbow fish. He soon developed “multiple tank syndrome” – a colloquial term used by fish collectors to denote the spiral commonly experienced after acquiring one’s first tank, which involves the sufferer buying many more tanks within a short space of time. He has not stopped collecting since.
Now, George sees himself as a conservationist; his tanks contain what is known as “insurance populations” – populations of endangered fish that are likely to go extinct in their natural habitats. He believes that when the time is right, they can be taken from his collection and returned to their homes. “I would never accept the fact that they couldn’t be reintroduced,” he says.
