Actually, that's not true - I've produced plenty of open source software over the years.  However, in a sense, it is true: only the very best actually get paid to work on open source software full time, and I'm not one of them.  People like Linus Torvalds.  People like Guido van Rossum, although even he supposedly divides his time, and does not work on Python full-time. Think about that.  Python is a hugely popular programming language used by many companies and individuals who get a lot of value out of it. But the creator doesn't even work on it full-time. Now, that's jus...

Image lazy loading is a concept where images are getting loaded only when needed. It has been adopted in many web applications to reduce usage of bandwidth. When a web page is loaded in a web browser, not all the page elements would be visible in the view port, hence those resources(images, videos etc) don't need to be loaded. Currently there are quite a few open source plugins on Github which can help achieve image lazy loading. Today we will introduce a few of them.Echo.jsEcho.js is a standalone JavaScript image lazy loading plugin, it doesn't rely on any other third party library. Its ...

A study of how 31 popular open source code libraries were downloaded over the past 12 months found that more than a third of the 1,261 versions of these libraries had a known vulnerability and about a quarter of the downloads were tainted.

This post will introduce how to undo changes with git command in different cases.Undo commitA common undo case is that some commit needs to be reverted as the commit contains error. In this case, the code is already committed. The command to revert the commit isgit revert HEADThis command will add new a commit to the existing head to undo the previous commit. It will not change the previous commit history, hence there is no risk of losing changes.If need to revert multiple commits, run...

While using Git to version code, programmers would inevitably perform some invalid operations which are not expected. Sometimes it's difficult to deal with this kind of awkward situations. If the programmer chooses to undo the operation, the programmer needs to bear the risk of deleting something which is not supposed to be deleted if the undo is done improperly. If the programmer leaves it as is, the file needs to be updated again manually with a new commit. In this post, we will try to provide advice on how to properly undo wrong operations performed using Git for some scenarios. G...
