Gold is the most popular commodity and is very active in trading. Whenever the global economic downturn or the world political turmoil, gold prices are often excellent as a safe-haven asset. For those who want to get involved in gold, they may want to know: How much is the highest and lowest gold in history? Let’s give you a brief introduction.

Combining relevant information from foreign English websites, we learned that the period from 1973 to 2020:

1. the lowest price in the history of gold is:

In January 1973, the price was $65/oz.

2. The highest price in the history of gold is:

In 2011 (September-November), the price was in the $1700-$1920/oz range.

3. the latest price of gold:

As of July 26, 2020, the latest price for gold is$1,902/oz. Gold prices are soaring in 2020 as a result of the global outbreak of corona virus (COVID-19). The current price is very close to the historical high, if the trend develops, 2020, gold prices are expected to break through the historical high, forming a new high.

As for why gold’s all-time high came in 2011, it is generally believed to have been due to the then euro debt crisis of 2011 and worsening inflation.

In addition, according to the relevant information, if dating back to the earlier 1792, gold’s all-time lowest price was: $19.39.

Posted on by — No Comments ↓

我们前面介绍的ExpressVPN运行环境多为苹果的iPhone iOS系统，那么ExpressVPN能否在中国国内的Android手机（如华为荣耀9、谷歌Pixel、小米等）上运行并连接服务器呢？我们酷贴集（allthecooltips.com）结合实际测试情况给大家做个介绍。

根据我们最新的测试，截至2020年7月14日，ExpressVPN可以在Android上顺利安装运行。我们使用的测试环境是华为荣耀9机型手机，运行Android为：8.0.0，EMUI版本也是：8.0.0。

安装前需要到ExpressVPN网站下载Android手机的app安装包（.apk文件，大小约26M），保存到手机本地文件夹，点击安装。由于ExpressVPN安装包已经制作的非常智能，安装后通常就可以使用了。因此您无需输入用户名、密码或激活码。

安装成功后，打开ExpressVPN的app，对于国内的国内用户，建议服务器选择官方推荐的服务器如香港-4。我们用4G网络连接测试，速度很快，大约2-4秒到连接完成，网速也相当流畅。对于使用安卓手机需要使用VPN的用户，我们强烈推荐ExpressVPN。

How to auto wrap texts within the HTML pre tag using CSS code?

Posted on by — No Comments ↓

For those of you who use WordPress a lot, the <pre> tag will help you retain the existing format of a particular text or code without making any changes. One problem with using the <pre> tag directly is that it doesn’t wrap text automatically, and sometimes it makes content hard to read because visitors need to scroll back and forth.

So how do you get text inside the <pre> tag to wrap itself? You can use CSS to achieve the content contained in <pre> automatic line wrapping, the specific code is as follows:

pre {
white-space: pre-wrap; /* css-3 */
white-space: -moz-pre-wrap; /* Mozilla */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
word-wrap: break-word; /* IE 5.5+ */
}

Linux vi command q vs q! — what is the difference?

Posted on by — No Comments ↓

Vi (or Vim) is the famous text editor on Linux operating system, it support the command q and q! (q followed by an exclamation mark), which look like almost the same, but is that true? what is the real difference between the two similar commands?

Here is a quick answer. The q command (:q) quit the current text file without saving, while the q! (:q!) forces a quit. If you opened a file in vi and made no changes to it, using q command will be enough. However, if you opened a file and already made a few changes to it, you have to use q!. This command will ignore all the changes made and allow you to do a forced quit.

Is PureVPN currently working in mainland China? (updated 2020)

Posted on by — No Comments ↓

Recently, the status of some VPN services in mainland China has not been stable. As one of the most popular VPN vendors in the world, PureVPN has a lot of users from China, but does PureVPN currently work in mainland China?

To answer the question, we have done some connectivity testing in a real environment (i.e., from China), so that we can have a better and accurate understanding of how PureVPN works in China. 

Let’s take a look at the testing environment and results:

We tested PureVPN on Windows 10 and Apple’s iPhone system. As of 30 May 2020, the results of the tests are as follows:

  • Windows 10 System Connection PureVPN Status: working
  • Apple iPhone iOS connection PureVPN status: working

It is important to note that in the above tests, we did not use PureVPN’s official client software or the official mobile phone app. On Windows 10 systems, we used a secure third-party client. On the iPhone, we used iPhone’s built-in VPN client.

On Windows 10, we successfully obtained an IP address in Switzerland after connecting to a VPN server. The iPhone, also connected to the Swiss server, received a Swiss Zurich IP address. On the computer and mobile phone system, the stability and speed of VPN connections are good, but overall, the stability of the mobile phone app is better.

Overall, PureVPN’s work well in mainland China on both PC and iPhone. So if you are looking for a working VPN in China, you should give PureVPN a try.
