《 Afflux weekly 》 The first 275 period ： Share the strongest security key C Code rules Practice Manual , Open source 2D Vector graphics rendering Library , Open source C Library and data structure software package SC, Every function can be ported

1、 The strongest safety key C Code rules Practice Manual , Not one of them.

anssi-guide-rules_for_secure_c_language_software_development-v1.4.pdf (1.06 MB)

In the past C Books on the subject , Or hundreds of thousands of pages thick , Or all kinds of obscure C How to play , After learning, I can only use if else, The advanced playing methods in the book are completely forgotten , Mainly, it is not so practical , not essential .

This time I will share with you the key to safety C Code abandons tradition C The compilation routine of books , Give the rules directly , Recommend ways , References and specification codes , Non standard code display , Greatly convenient for your reference .

2、 Open source 2D Vector graphics rendering Library LinaVG

It can render anti aliasing shapes , Support gradient colors , line , outline ,SDF Text etc. .

GitHub - inanevin/LinaVG: 2D Vector-Graphics library for drawing anti-aliased convex shapes, lines and texts.

3、 The name is a little dirty , But it's serious programming JSFuck

JSFuck - Write any JavaScript with 6 Characters: []()!+
GitHub - aemkei/jsfuck: Write any JavaScript with 6 Characters: []()!+

JSFuck It's based on JavaScript The abstruse and educational programming style of atomic part . It uses only six different characters to write and execute code .

It's not browser dependent , So users can even Node.js Run it on .

For example, the following code is executed alert(1)

[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[
]]+(!![]+[])[!+[]+!+[]+!+[]]+(!![]+[])[+!+[]]][([][(![]+[])[+[]]+([![]]+[][[]

4、 Small software that supports hundreds of file format parsing FQ

download ：Releases · wader/fq · GitHub

instructions ：fq/usage.md at master · wader/fq · GitHub

It was originally designed for queries 、 Check and debug multimedia formats , Such as mp4、flac、mp3、jpeg, Now it has been expanded to support hundreds of formats .

Windows Next , Use scoop Commands can be easily installed

8、 Open source C Library and data structure software package SC, Every function can be ported

GitHub - tezc/sc: Common libraries and data structures for C.

features ： High performance , Minimum code requirements , Each function has its own C and H file , It is convenient to transplant and use alone .

What's more valuable is that there are corresponding play examples in each file , It's very convenient .

For example, use linked lists ：

9、ST news

（1）ST Release motor reference design , Suitable for power up to 250W Reference design of industrial compressors and household appliances .

STEVAL-CTM011V1 - eStore - STMicroelectronics
