As a programmer, the computer is the most important tool, and it is also the job of the programmer. Without a job, it is absolutely impossible. Therefore, it is very important for us to maintain our computer in our daily work. Let me talk about the computer and maintenance-related things from several aspects of myself. First, I will upload a picture of my computer, as shown below:
1. Suggestions on computer selection
1.1. Price budget
This is very important. You need to know the maximum price you can afford. The higher the price you can afford, the more choices you have. If you have enough money, you can buy a computer in the right range. If you want to be good in all aspects, in the end Your budget can't afford it, because there is no best, only better...
1.2. Clear requirements
Is it necessary to buy a computer by yourself? What is the computer used for? For example, just processing documents or something. A budget of less than 5,000 is enough. If you do UI-related work, you may have higher requirements for the computer, and the price budget will be higher. .
1.3. Computer configuration
The most important configurations must be selected well. For example, the processor, memory, and hard disk are all things that have an important impact on computer performance. When choosing a place, you must choose a better one.
1.4. Resolution
Generally, 1080P resolution is enough. If you have higher requirements for image processing, you can choose a 2k or 4k resolution screen.
1.5. Battery life
If you are outdoors for a long time, battery life will also be a consideration, because you need to deal with some urgent matters outside, and the battery life is strong, and you will feel more at ease and feel better.
1.6. Brand selection
The choice of brand can be considered in terms of price, after-sales service, personal habits, user experience, personal preferences, etc. For example, some people like to use Apple computers, like its habits and user experience, and price may not be the top priority. So let’s make a choice after weighing the above aspects.
1.7. User Evaluation
You can go to the Internet to read some opinions of various evaluation bloggers. They can evaluate from various aspects, so that you can fully understand all aspects of the computer.
1.8. Comparison of various e-commerce platforms
You can check various e-commerce platforms, and compare the price, sales volume, user evaluation, parameter configuration, etc. of a certain computer model on sale.
1.9. Final decision
According to the above suggestions, see which aspects you pay the most attention to, which ones you can accept, compare all aspects, and finally choose the most suitable computer for you, and the one that suits you is the best.
2. My choice
I had been working for several years at that time, and I used a Windows system computer (Lenovo) before, so I wanted to change to a better one, and the considerations were as follows:
First of all, the user experience of computer use should be good, and the interface should look stylish and written, mainly for writing codes.
Secondly, I want to try another computer system.
Finally, it is easy to carry, has strong battery life, and better performance, and there are not many other requirements.
In short, after some consideration, I chose the MacBook pro 2018 model. It has been used for almost 5 years, and I feel that it is very good.
The following are some parameters:
Processor: Quad-core inter Core i5
Memory: 16G
Hard disk: 512G
3. Computer maintenance
3.1 External cleaning
The keyboard, screen, and casing need to be cleaned regularly. Try to use special tools for operation. You can buy a cleaning kit online.
The keyboard needs to get a suction ball to blow off the dust on it, and clean it with a clean small special cloth.
The screen can be wiped off with a special cleaning solution.
The entire exterior of the computer can be wiped down with a clean rag or wipe.
3.2 Install the software
Install some commonly used genuine software, so when downloading software, be sure to download and install it from a place with a high degree of trust. Some software may contain viruses, which will affect the use of the computer, and may cause data leakage in serious cases. loss of funds and more.
3.3 Optimizing the operating system
It is necessary to update the system regularly, install system patches and the latest security updates, and improve system security, stability, robustness, etc.
Regularly delete unnecessary files and empty the trash files in the recycle bin.
Safe and reliable anti-virus software can be installed to scan all the codes of the system to avoid virus files. Check the scanned files again by yourself, because some anti-virus software often give false positives.
3.4 Maintain hardware equipment
Avoid placing the computer and power supply in high temperature and other dangerous places, and be careful when plugging and unplugging the interface, and do not use violence to cause poor contact of the interface.
It is necessary to deal with the heat dissipation of the computer vents. If the temperature is too high, you can buy a small electric fan to blow it, or buy a computer stand to stand the computer up for ventilation and heat dissipation.
The two ends of the power cord are generally very easy to be damaged, and it is easy to be damaged when it is folded up. You can buy a packaging wire and wrap the entire wire around, which can better protect the outer layer of the wire from damage.
Do not turn off the computer for a long time, so that some of the computer is in a working state, and the whole computer is running all the time. If this is the case for a long time, the computer is easy to freeze, and the corresponding equipment is easy to age.
To prevent computer overload, that is, other people's computer CPU and memory are at close to 100% utilization rate, such a high-load operation can easily cause the computer to crash or burn out the device.
The equipment needs to work at a suitable temperature. If the temperature is too high or too low, the equipment will be damaged.
3.5 Power Management
You need to save electricity, adjust your own power management plan reasonably, and use it reasonably, in order to better extend the service life of the battery. When plugging in, connect to a stable power outlet to avoid battery damage caused by unstable voltage.
3.6 Data backup
Data backup needs to be done regularly to prevent data loss, data incompleteness, data tampering and other risks.
3.7 Security
Security includes equipment security and network security, both of which will have a profound impact on the equipment itself or other aspects of us, so we must always pay attention to it.
The password setting is updated regularly, and a certain complexity needs to be met when setting a new password (for example: the length is at least 20 characters, including uppercase and lowercase letters, numbers, special symbols, etc.)
Install antivirus software
Turn on firewall settings
Try not to store sensitive data on your computer
Regarding network security, refer to the encyclopedia entry: Network Security
