                Don't use Vim for the wrong reasons
              
          
    Don't use Vim


Don't do the crime, if you can't do the time.
-- Anthony Vincenzo "Tony" Baretta

Vim is an amazing text editor. I love it. Really, I wouldn't [organize][organize] a Vim advent calendar if I didn't. But, as amazing as it is, Vim is not for everyone. It can't solve all your problems, or be a TUI version of your favorite IDE, or make you a better programmer, or land you that dream job in the Bay Area. But Vim can help you be more mindful, focused, and efficient, as long as you approach it with the right mindset.
Don't get me wrong, I certainly welcome you to try Vim, but I'm not a proselyte. I don't thrive on newbies. I just want you to use the right tool for the job and not waste your—and anyone's—time on a fruitless quest.

    CVE-2020-8597 - Buffer Overflow in pppd

In this short tutorial we will go over how to reproduce the crash from CVE-2020-8597.  This is a stack-based buffer overflow in the pppd binary.
We will use our own pppd binary compiled from source, using the latest version: 2.4.8.
To accomplish this goal, we will need two Virtual Machines connected by a virtual serial port.  I typically use VirtualBox since it is open source, but the same sort of configuration should work on other hypervisors.
I spun up two VMs:

  
## aggregator.go
//这个方案需要实现以下几点：
//1.消息聚合后处理（最大条数为BatchSize），核心：
//（1）带buffer的channel相当于一个FIFO的队列
//（2）多个常驻的goroutine来提高并发
//（3）goroutine之间是并行的，但每个goroutine内是串行的，所以对batch操作是不用加锁的。
//2.延迟处理（延迟时间为LingerTime）
//  注意：为什么使用time.Timer而不是time.After，是因为time.After在for select中使用时，会发生内存泄露。
//3.自定义错误处理
//4.并发处理

## colorize-emacs.bashsource
# sourcing this file will define a bash functions that
# tries to run subsequent calls to emacs with 24 bit color.
#
# It sets TERM=xterm-emacs-leg if
# - we've created a user-local terminfo record for xterm-emacs-leg, and
# - we're using iTerm2 or something has set COLORTERM=truecolor
#
# This will cause emacs to use 24 bit color only when it will work,
# inside or outside of tmux. I haven't found a way to auto-detect Blink.sh yet.

    Rust maintainer perfectionism, or, the tragedy of Alacritty

I did not submit this to Hacker News and did not intend that this post would have high circulation but have no real problem with it being there or with it having such. I have more recent comments below. This post is from January 2020 and predates the Modular Font Editor K (MFEK) project.
I have not worked on Rust projects in quite a while, and don't know if I ever will again. I feel many crate maintainers are way too perfectionist, for example, despite all the developer hours that went into this PR, it took the effort within years to be (halfway) merged.
There's always a reason not to merge, isn't there? It would be better done with a new nightly language feature, or the function signature should have a where clause, or the documentation is not perfect. There's always a new nit to pick in the world of Ru
