ReplyDeleteThe very issue of programming is certainly interesting and if someone has a strict mind I think that he can become a programmer. For me, reading the blog https://grapeup.com/blog/ is completely enough for me because I know how much interesting information I can get from it. The more that I am an advanced user of applications running in the cloud.
