transfer. If you want to hear some legendary experiences, I'm afraid you will be disappointed.Pai_^ I graduated from college in 2001. I was interested in and enthusiastic about computers during my college years. I used my spare time to buy university computer teaching materials for self-study, before graduation, I got a certificate of Computer Level 3 B. After graduation, I joined a software company and ma

difficult to learn. For example, there are some important technologies in Apache and Nginx, such as system tuning and service optimization, and program optimization, which is difficult to learn before working in contact with the work, so let's take this 10 to learn. It's hard to know that you have to learn to do it for at least 3 months, and that part of the script is exhausting.

The responsibility of network engineers is to maintain the network security of an enterprise, because the storage and utilization of data in an enterprise is very important. It is related to the operation of an enterprise. Therefore, if security problems occur, the loss to the company is in

electronic engineer in a medical equipment company there. On the edge of Taihu Lake, we chatted about our work, hardware and software. I told him that the top software engineers in the world should be people with their heads shining and even sparks from their hair when thinking about problems. Software engineers must have an idea, because the software itself is a pile of ideas. There is nothing but an idea

Ten Tips for young engineers]Lemontree published on 8:52:00 1 Recommended[Transfer] Ten Tips for young engineersYou guys, I have been an electronic engineer for more than ten years. I don't know how to make a profit. I didn't even see a few promising people around me! Looking back on the engineer's career, I am deeply touched. If I want to say a few words, I hope they will be better than us![1] plan your own path and

From being more familiar with open source software to developing applications (apps), industry experts are encouraging embedded engineers to get out of the comfort circle and learn new skills to keep pace with the times.Looking back at the 1980-year-old embedded field, engineers at the time were designing mixed-signal circuits, connecting microcontrollers, writing low-order codes, and taking back product pr

Can stick to here is not easy, learning Linux is the most important thing is to tap the keyboard, not like windows as a graphical point to point to, the advantage is that Linux no graphics compared to save memory, and for Linux novice, it is recommended that you do not bare-metal installation of Linux system, l

IDs), then it can make memory consumption grow fast. LinkedIn used to stumble on this--it was the intern method for some key values, and everything was fine when the offline simulation was done, but once deployed, the system's memory took up (because a large number of unique strings were intern). So finally LinkedIn chooses to use the LRU cache, which limits the maximum number of elements.Final resultThe SPR memory footprint is reduced by 75%, reducing the memory footprint of the Feed-mixer by
