这个有意思，现在最热门的话题，测试后，内容后补......

市面上又百度云，Onedrive，dropbox、icloud、wps云盘、坚果云、阿里云盘......等优秀的在线网盘工具。那么，一般的公司还有必要建设自己nextcloud云盘应用吗？

为了回答这个问题，我们先来对优缺点进行简单的分析。

共同的优点：对个人使用非常友好。

1. 这类在线网盘适合用来存放个人文件，比如照片、视频、大文件，占用上百G的空间都没有问题，无非付费的问题。
2. 适合以家庭为单位进行组团使用，可以共用一个账号，也可以手机号注册后，彼此加为好友即可。

缺点：不适合公司内使用

1. 企业敏感重要的数据并不适合存放在第三方平台，特别是对于一些初创的公司。
2. 共享写作不方便，企业用户用私人手机号拥有文件，不够正规职业化之外，还存在文件泄密等风险。
3. 用来做文件的存储功能强大，但是协作功能很弱小。

So....

必须要建立公司自有的私有云

美國總統911都依靠BlackBerry與外界通信，高安全高價格實时推送資訊，我也曾經擁有多部開通BlackBerry服務並引以為榮！

BlackBerryOS將會在2022年1月4日起停止支援。

受影響的包括BlackBerry 10、BlackBerry 7.1或更早的版本，届時使用BlackBerry OS的裝置部份基本功能，例如撥打電話及收發SMS短訊亦可能出現問題，另外一些例如BlackBerry Link、BlackBerry Desktop Manager、BlackBerry World、BlackBerry Protect、 BlackBerry Messenger及BlackBerry Blend等功能都會受到限制。

科技的命運就像BlackBerry，落後的結果就是……

Say goodbye to BlackBerry!

BlackBerry迴響出來的事實就是，用任何邏輯或者解析的方法去解析，但當所有人認為你是沒有用的，你就是沒有用的！ 祝商祺！

再見!

For a freelancer, nothing is more important than time. Tracking invoices or doing paperwork can quickly become tedious and occupy a large portion of that. In March, I showed you FusionInvoice, a tool to keep track of your clients and invoices. Although it’s a nice and easy to use tool, its open-source version has since been discontinued and in part taken over by InvoicePlane. In this post, however, I’d like to introduce you to InvoiceNinja.

很多人一想到统计的话都会仅限于Google Analytics、百度统计、站长统计等，这类的统计都是搜索引擎等第三方公司开发的系统，在功能上和易用性上自然没话说，但是唯一一个问题就是统计数据存储放在了第三方的服务器上，对于一些保密性强的网站那就存在一定的风险了。

另外一个使用第三方的Web统计存在的问题就是不安全性，例如之前也有爆出百度统计、站长统计等JS文件有挂马以及统计服务器宕机的情况。Google Analytics虽然没有出现过较大的问题，但是Google Analytics却经常无法访问，这严重影响了网页的加载速度，这也是我不得不放弃GA的原因。

Nextcloud is a suite of client-server software for creating and using file hosting services. It is functionally similar to Dropbox, although Nextcloud is free and open-source, allowing anyone to install and operate it on a private server. In contrast to proprietary services like Dropbox, the open architecture allows adding additional functionality to the server in form of applications.

     'port' => 6379,
      ),
  'memcache.locking' => '\OC\Memcache\Redis',

nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and windows WSL.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

Running either of the above commands downloads a script and runs it. The script clones the nvm repository to ~/.nvm, and attempts to add the source lines from the snippet below to the correct profile file (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

WSL 即 Windows Subsystem for Linux，是 Windows 的 Linux 子系统，本质是在 Windows 上原生运行 Linux 二进制可执行文件（ELF 格式）的兼容层。

WSL 提供了一个由微软开发的 Linux 兼容的内核接口（不包含 Linux 内核代码），然后可以在其上运行 GNU 用户空间，例如 Ubuntu、openSUSE、SUSE Linux Enterprise Server、Debian 和 Kali Linux。这样的用户空间可能包含 Bash shell 和命令语言，使用本机 GNU/Linux 命令行工具（sed，awk等），编程语言解释器（Ruby，Python 等），甚至是图形应用程序（使用主机端的 X 窗口系统）。

An image format for the Web
WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.

WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.

Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing 3× smaller file sizes compared to PNG.
