Welcome to the Gutenberg Editor

Of Mountains & Printing Presses

The goal of this new editor is to make adding rich content to WordPress simple and enjoyable. This whole post is composed of pieces of content—somewhat similar to LEGO bricks—that you can move around and interact with. Move your cursor around and you’ll notice the different blocks light up with outlines and arrows. Press the arrows to reposition blocks quickly, without fearing about losing things in the process of copying and pasting.

What you are reading now is a text block the most basic block of all. The text block has its own controls to be moved freely around the post…

… like this one, which is right aligned.

Headings are separate blocks as well, which helps with the outline and organization of your content.

A Picture is Worth a Thousand Words

Handling images and media with the utmost care is a primary focus of the new editor. Hopefully, you’ll find aspects of adding captions or going full-width with your pictures much easier and robust than before.

Beautiful landscape
If your theme supports it, you’ll see the “wide” button on the image toolbar. Give it a try.

Try selecting and removing or editing the caption, now you don’t have to be careful about selecting the image or other text by mistake and ruining the presentation.

The Inserter Tool

Imagine everything that WordPress can do is available to you quickly and in the same place on the interface. No need to figure out HTML tags, classes, or remember complicated shortcode syntax. That’s the spirit behind the inserter—the (+) button you’ll see around the editor—which allows you to browse all available content blocks and add them into your post. Plugins and themes are able to register their own, opening up all sort of possibilities for rich editing and publishing.

Go give it a try, you may discover things WordPress can already add into your posts that you didn’t know about. Here’s a short list of what you can currently find there:

  • Text & Headings
  • Images & Videos
  • Galleries
  • Embeds, like YouTube, Tweets, or other WordPress posts.
  • Layout blocks, like Buttons, Hero Images, Separators, etc.
  • And Lists like this one of course 🙂

Visual Editing

A huge benefit of blocks is that you can edit them in place and manipulate your content directly. Instead of having fields for editing things like the source of a quote, or the text of a button, you can directly change the content. Try editing the following quote:

The editor will endeavor to create a new page and post building experience that makes writing rich posts effortless, and has “blocks” to make it easy what today might take shortcodes, custom HTML, or “mystery meat” embed discovery.

Matt Mullenweg, 2017

The information corresponding to the source of the quote is a separate text field, similar to captions under images, so the structure of the quote is protected even if you select, modify, or remove the source. It’s always easy to add it back.

Blocks can be anything you need. For instance, you may want to add a subdued quote as part of the composition of your text, or you may prefer to display a giant stylized one. All of these options are available in the inserter.

You can change the amount of columns in your galleries by dragging a slider in the block inspector in the sidebar.

Media Rich

If you combine the new wide and full-wide alignments with galleries, you can create a very media rich layout, very quickly:

Accessibility is important — don’t forget image alt attribute

Sure, the full-wide image can be pretty big. But sometimes the image is worth it.

The above is a gallery with just two images. It’s an easier way to create visually appealing layouts, without having to deal with floats. You can also easily convert the gallery back to individual images again, by using the block switcher.

Any block can opt into these alignments. The embed block has them also, and is responsive out of the box:

You can build any block you like, static or dynamic, decorative or plain. Here’s a pullquote block:

Code is Poetry

ESLpod | 2 Getting Up

Complete Transcript

Welcome to English as a Second Language Podcast number 2: Getting Up

This is English as a Second Language Podcast episode number two. I’m your host, Dr. Jeff McQuillan, coming to you from the Center for Educational Development in beautiful Los Angeles, California.

This episode begins a special 10-part series covering basic vocabulary for everyday actions, from getting up in the morning to going to bed at night and everything in between. We’ll start with getting up.

Let’s get started!

[Start of story]

The worst part of the day for me is definitely when I have to get up. Waking up, that I can handle. But getting up? That, I hate. The covers I have on my bed are heavy, mostly because I have a comforter as well as a light blanket. I sleep with two pillows, which for some reason have different color pillowcases. Well, at least the sheets match.

I sometimes wake up before the alarm goes off. I like to keep the alarm at a low volume, with some classical music, nothing too jarring. My old roommate used to like the terrible buzzer that you find on most alarm clocks nowadays, which always used to drive me nuts. As I was saying, I sometimes wake up before the alarm, usually because of some noise outside the house—a car door slamming, an alarm going off, gunfire—well, okay, not gunfire, but man, is my neighborhood noisy! Of course, when I’m staying in a hotel, it’s usually easier to just get a wake up call from the hotel than set the alarm.

I’m not really an early riser, so I don’t jump out of bed ready to take on the world. I get up very slowly, usually one foot on the floor at a time. Every once in awhile I’ll oversleep, but not too often. I really love the weekends, when I can sleep in.

[End of story]

Our story begins by me describing how much I do not like getting up. To get up means to get out of your bed, to stand up after you have been lying down on a bed. I say that, “The worst part of my day is when I have to get up. Waking up, that I can handle.” To wake up “wake up” (two words) means that you are sleeping and you stop sleeping and now you are awake. The verb is to wake up. So, you can wake up while you are in bed, and then, you get up—you stand up after lying down.

I said that “waking up” is something “I can handle.” To handle (handle) here means to be able to control—something that I can manage—something that I can accept; it’s not a problem. Another expression would be something I can deal with. To deal “deal” with something is the same, in this case, as to be able to handle something.

I say that “getting up” is something that “I hate.” The covers I have on my bed are heavy.” The covers (covers) are the things that you put over you to keep you warm. Usually, the covers include a blanket, sometimes a comforter and usually, what we would call the top sheet or flat sheet. A comforter “comforter” is a very thick blanket, a very heavy blanket. A blanket (blanket) is something that you put over you when you are sleeping to keep you warm.

Blanket is a general term; a comforter is a kind of blanket, a heavy blanket. The opposite of a comforter would be a light blanket. A light (light) blanket would be the opposite, and that is a blanket that will keep you warm, but if it gets very cold, it might not keep you warm, it might not be sufficient.

So, we have a comforter and we have a light blanket. Usually, there is a top sheet (sheet) that you put over you in between your body and the blankets, and this top sheet is sometimes called a flat sheet. The sheet that goes on the bed itself, that goes onto the corners of the bed, that’s called a fitted sheet, a fitted (fitted) sheet. So, we have a fitted sheet on the bed that you sleep on top of, then we have a top sheet and then a blanket, sometimes, if it’s very cold, a comforter as well.

I say in the story that “I sleep with two pillows.” A pillow (pillow) is what you put your head on when you sleep. Now, “for some reason,” I say I “have different colored pillowcases.” This is true, actually; I have a black pillowcase and a blue pillowcase for my two pillows. I think the reason is I am too lazy to go and buy a new pillowcase.

Well, the pillowcase “pillowcase” (one word) is the thing that you put over the pillow so the pillow doesn’t get dirty; we call that the pillowcase. I say, “Well, at least the sheets match.” We already know what a sheet is. When we say the sheets match (match), we mean that they are the same color or two colors that look good together. We use that verb, to match, when we are talking about clothing as well, or anything where you have two colors.

“I sometimes wake up before the alarm goes off.” When we say the alarm “goes off,” we mean that the alarm starts to make a sound. Your alarm (alarm) is a machine that makes noise at a certain time; usually it has a clock. Well, I sometimes wake up before my alarm makes noise, my alarm goes off. “I like to keep the alarm at a low volume,” meaning not very loud – at a low volume – “with some classical music, nothing too jarring.” When we say a sound is jarring (jarring), we mean that it is loud and it causes you to jump or to be surprised. It’s something that is not very nice, not very pleasant. A jarring noise would be one that bothers you, perhaps because it is very loud or it is not a very nice sound. So, I don’t want my alarm to have a jarring noise; instead, I play classical music.

Now, “My old roommate”—the person I used to share an apartment with— “used to like the terrible buzzer you find on most alarm clocks.” This, again, is true. I had a roommate that had a very loud and bad sounding buzzer; it was a terrible buzzer. The buzzer (buzzer) is when the alarm clock doesn’t play music, but it just plays a sound. Sometimes it is like a bell ringing; that’s the buzzer. Well, this buzzer always used to drive me nuts. “To drive someone nuts” (nuts) means to drive them crazy, to make them crazy, to make them go crazy.

I continue the story by saying, “As I was saying.” We use that expression, “as I was saying,” when we are talking about one thing then we start talking about a second thing, and now we want to go back and talk about the first thing again. So, when you interrupt yourself when you are talking, and then you change the topic, change what you are talking about, and then want to go back to your original topic, you say, “As I was saying.”

“As I was saying, I sometimes wake up before the alarm, usually because of some noise outside the house.” When we say there is some noise, some sound, outside the house or outside of the house – you can say either one – we mean that someone is making a noise that is very loud. Some of those noises are “a car door slamming.” The verb “to slam” (slam) means that you close the door usually very quickly and you make a loud noise. Someone closes their car door very fast, it will make a noise. We call that “slamming the door.”

My mother always used to tell me when I was young, “Don’t slam the doors,” meaning when I come in and close the door, I should close it slowly and quietly. Of course, I was not a good boy so I would sometimes slam the door.

As I was saying, an alarm goes off, that’s another noise that can wake you up outside and this would be a car alarm. Here in Los Angeles, everyone has a car alarm, and sometimes those alarms go off at night. Another noise is gunfire; “gun (gun) fire (fire).” Gunfire is when someone shoots a gun and it makes a noise. This is, again, Los Angeles, so we sometimes have gunfire – but of course, I’m joking. I say, “Well, okay, not gunfire,” meaning I’m just kidding, that isn’t actually true, although, it is true sometimes.

I then say, “Man, is my neighborhood noisy!” That expression, “man,” is just a way of expressing your emotion when you are saying something that you really mean or really want to emphasize. “Man, is my neighborhood noisy!” – that means my neighborhood is very noisy.

“Of course, when I’m staying at a hotel, it’s usually easier to just get a wake up call from the hotel.” A “wake up call” (call) is when the hotel calls you on the phone to wake you up so you don’t have to set your own alarm. “To set” (set) an alarm means to turn it on and to put a certain time that you want to get up. Well, sometimes people have problems with their alarm clocks and so, if they are in a hotel, they can ask the hotel to wake them up with a wake up call.

At the end of the story I say, “I’m not really an early riser.” An “early (early) riser (riser)” means someone who wakes up and gets up very early in the morning. You could be an early riser; you could be a late riser. The word “riser” comes from the verb “to rise (rise)” which, in this case, means to get up. Well, “I’m not really an early riser,” I say, “so I don’t jump out of bed.” “To jump out of bed” means to get out of bed very quickly. “I don’t jump out of bed ready to take on the world.” “To take on the world,” means I’m ready for the day. It’s an expression we use to say that I am ready to go out into the world and do my best. “I’m not an early riser, I don’t jump out of bed ready to take on the world.” Instead, “I get up very slowly, usually one foot on the floor at a time.” So first, I get up and I put one foot on the floor, and then another foot on the floor, and then I stand up.

“Every once in awhile,” I say, “I’ll oversleep.” “To oversleep” (oversleep) – one word – means that you sleep later than you should. For example, you are wanting to get up at seven o’clock in the morning and you sleep until 7:30. You don’t realize that you are sleeping too late; we call that “oversleeping.” To oversleep means you sleep longer than you wanted to.

At the end of the story I say, “I really love the weekends” – Fridays and Saturdays – “when I can sleep in.” “To sleep in” means that you don’t get up at your normal time; you sleep longer than you normally do. So, if you normally get up at seven, on Saturday or Sunday if you don’t work, you may sleep in until nine a.m.

Now let’s listen to the story, this time at a native rate of speech.

The covers I have on my bed are heavy, mostly because I have a comforter as well as a light blanket. I sleep with two pillows, which for some reason have different color pillowcases.

[End of story]

Her scripts are never jarring, but always as wonderful as classical music. I speak, of course, of our scriptwriter, Dr. Lucy Tse. Thank you, Lucy!

From Los Angeles, California, I’m Jeff McQuillan, thank you for listening. Come back and listen to us again right here on ESL Podcast.

Culture Note

Librarians

Librarians help people find information from many sources. Most librarians, such as those in public and “academic” (school or college) libraries, maintain library “collections” (materials) and do other work as needed to keep the library running.

In small libraries, librarians are often responsible for many or all aspects of library “operations” (the daily activities and service provided). They may manage a “staff” (group of workers) of library assistants. In larger libraries, librarians usually focus on a specific area, such as helping users or “overseeing” (supervising) technology, while others focus on specific areas of knowledge, such as science or literature.

Librarians often help “patrons” (users of services) find the information they need. They listen to what patrons are looking for and help them research the subject using both “electronic” (computer-based) and “print” (paper-based) resources. Librarians also teach patrons how to use library resources to find information on their own. This may include familiarizing patrons with “catalogs” (listings or files organized for easy finding) of print materials, helping them access and search “digital” (electronic) libraries, or educating them on “Internet search techniques” (how to find information on the Internet).

Most librarians need a “master’s degree” (two-year degree after completing one’s bachelor’s degree) in library science. A bachelor’s degree is needed to enter a graduate program in library science, but any undergraduate “major” (focus of study) is accepted.

Colleges and universities have different names for their library science programs. They are often called Master’s in Library Science (MLS) programs but sometimes have other names, such as Master of Information Studies or Master of Library and Information Studies. Many colleges offer library science programs, but, as of 2011, only 56 programs in the United States were “accredited” (given official recognition or permission) by the American Library Association. A degree from an accredited program may lead to better job opportunities.

让我对人生许个愿

年轻的时候,看了许多的漫画,美剧,日剧。

不仅让我喜欢了足球,篮球,也让我知道了爱,知道了大陆以外的世界。

可年轻的时候奔来跑去,结了婚,生了孩子。

不知道为什么却从没有想过要去那两个国家看看,走走。

不知不觉,人生已经过去一半了。才猛然醒悟,我竟然没有去亲眼看过这些影响了我一辈子,珍爱了一辈子的文化。

所以,就让我对自己的人生许下这个心愿。

努力学习语言,在35岁之前出发,去北美,去日本生活。

去看看大空翼的静冈,逛逛樱木花道的湘湖,去看看伪装者的故乡,去落基山,去北美的西部。

就这么定了,先把英语学起来。

然后是日语

团队里来的新人3做3不做

身在职场的我们,总会需要融入众多的团队。这时我们该怎么办?是不是只要埋头苦干,多看少说就可以了呢?

似乎仅仅这样还是不够的!那到底我们该怎么做才能快速融入呢?

需要我们去做的事:

1. 认识每个人,知道每一个人的名字或花名、电话、QQ、邮箱,最好在第二天就能叫上每个人的名字。最好还能粗略知道每个人的性格。知道该怎么和他们相处。

2. 了解每个人,知道每个人具体在做什么,每一项工作谁在负责,各个工作时间是否存在依存关系等等。每个团队的工作就像是蛛网一样,牵连很多,往往很难

3. 学习每个人,知道每个人的能力水平,技能特点等等,这样能够让我们在工作时,快速找到可以帮助我们的人。

 

不能做的事情
1.
 评论,作为一个新人,除非特殊情况,千万不要评论任何团队的事情或团队里的人。因为我们还只是新人,不了解其中的各种历史,很难做出客观的评价。

2. 比较,不要将现在的团队和过去参加过的团队做比较。不论比较的结果怎么样,都会对我们目前的工作产品不良的结果。

3. 鲁莽,在参与团队工作的时候,因为我们对于团队历史了解并不多,所以千万要仔细,不要做一些鲁莽的傻事。比如不小心删除的了代码等等
