如果用下面一段话来描述真正的程序员,应该是恰当的: 这是一群热爱钻研技术的人,一群单纯而诚恳的人,一群不屑争名夺利的人,一群鄙视虚伪做作的人,一群富有激情又有梦想的人。但同时,这又是一群被认为是愣头青的人,一群不懂人情世故的人,一群在底层打
如果用下面一段话来描述真正的程序员,应该是恰当的:
这是一群热爱钻研技术的人,一群单纯而诚恳的人,一群不屑争名夺利的人,一群鄙视虚伪做作的人,一群富有激情又有梦想的人。但同时,这又是一群被认为是愣头青的人,一群不懂人情世故的人,一群在底层打拼却难走到高层的人,一群不被重视的人,一群经常被当作垫脚石和牺牲品的人,一群被现实生活压得喘不过气的人。
不可否认,称谓从“IT精英”到“IT民工”的转变,意味着现在的程序员生活得更加艰难。大环境当然是一个重要的客观原因,但是,我们个人主观方面也需要重新审视。是时候需要反思一下了,问题出在哪里?
仔细思量,我们从小就一直被灌输的“正确”思想,为什么在现实中并没有成为指导我们工作和生活的理论武器了?我们从小就被教育:要做一个诚实的人,一个正直的人,一个与人为善的人,一个积极勤奋的人,......。在现实中,无论是有意识的还是无意识的,我们一直是这样做的,可结果了?不要说实现理想,就连生存下去都有很大的压力。菜价涨了、房价涨了、油价涨了......,无不让我们倍感焦虑,没有安全感。
那么,是不是为了实现理想,我们就必需变得虚伪、变得世故、变得圆滑、甚至违背自己的良心、出卖自己的灵魂了?当然不是,这就从一个极端走向了另一个极端,从生活的困境走到了心灵的困境。
英雄通常有两种,一种是刚正不阿、宁死不屈、大义凛然的人。一种是低调潜伏、隐忍屈辱、等待时机的人。第一种人之所以能够成为英雄,通常是因为他们最后多成为了烈士;第二种人之所以成为英雄,香港服务器租用,往往是因为他们解救了天下苍生,改变了历史。我们当然需要烈士这不弯的脊梁,但我们更需要能完成解救天下重任的人。有时候,做烈士容易,而为了完成使命忍辱偷生地活下去,却需要更大的勇气。
回到我们程序员身上,我们单纯的特质更接近刚正不阿、宁死不屈、大义凛然,也更接近于成为烈士和牺牲品。在和平年代,对于我们普通人,虽不需要有解救天下的使命,但是,香港服务器,我们都有自己的重任。我们的重任是什么?说俗一点,就是养家糊口,让家里的妻儿老小不为衣食住行发愁。这是我们首要的目标,美国服务器,至于实现理想、大展抱负,那是后续的任务了。为了不违背自己的良心,我们不能出卖自己去当“叛徒”,为了我们的家人,我们不能去当牺牲品和“烈士”,我们不仅仅为自己而活。
就根本来说,程序员的特质更适合象牙塔的生活,在现实中、在职场中,这种特质虽不能说是缺陷这么严重,但却是真正的弱点。现实是复杂的,不能靠单纯来应对。职场如战场,职场即江湖。战场是残酷的,江湖是险恶的。只要身在职场,即使你是一个程序员,首先,你也需要保护好自己。
在职场中生存,需要技巧。在学习技巧之前,先要转变思想。想想下面的问题:
付出得多,就一定收获的多吗?好心一定有好报吗?只要兢兢业业、认认真真就能升职加薪吗?
上司是真正为公司的利益着想的吗?你把任务提前完成了,上司一定会高兴吗?上司表扬了你,你就感到开心吗?
你有想过自己会被兔死狗烹、鸟尽弓藏吗?有想到过自己是在为他人做嫁衣吗?有想过别人是在故意激怒你,以让你在失去理智的瞬间做出无法再回头的失当行为吗?

在IT这行做了10年了,从程序员一路走来,回望过去,无限感慨。期间许多职场心得,很乐于拿出来与大家分享,所以打算写“程序员在职场”系列文章,不知大家有没兴趣,如果有兴趣,我就继续写下去,欢迎大家批评指正。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
