driverless dilemma

I used a few days to quietly read the Javascript authoritative guide. A good book! This sentence is too many. What's better? Listen to me. It has been a year since I started to get in touch with JS, and my mind has always been a bit boring. This is also often said in forums. So where is it? I always feel that I am not going deep in learning. Some simple things can be done but cannot be done with ease. Can you tell me more about this bitter talk?

They all said, "I cannot tell you how to be specific? What is unspeakable? You can't say it, but you can't be specific. If you can't put the problem into practice, you can't solve it. Thi

feeling of hundreds of programmers I have come into contact with is that, unless the naturally appropriate talents can become the top experts in the industry, the vast majority of programmers can only be classified as "mediocre" according to the above standards, so our discussion here is mainly based on the majority of "mediocre" programmers.

important, how can we make the team develop good programming habits? Which programming habits are good? What is the root of software quality? Is it design or test? What does high-quality software mean to the work and life of engineers? Is the software architect important? Or is it just a virtual job? What skills do software architects need to master if important? CMM (software Maturity Model), which has a great influence in the software industry, advocates measuring the software development

these pages. That sounds good. But if there are only 10 lines of code, we create this file just to share the 10 lines of code? (Note: Overkill?) This approach is pure, but if the site is huge and there are a lot of things to share a few elements of the page (note: For example, 30 pairs of pages to share 10 lines of code), it seems very cumbersome. Create a separate CSS file that contains the styles for all shared elements. This method may be simpler, depending on the size of the site and the n

When I used the WINDOWS7 system, one time I downloaded the update, and when I was not installed, I just had to reboot the computer because of something, and I was asked if I should install and update it.

In fact, it is easy to solve, as long as we block the WINDOWS7 system of

dilemma of routing lookups. The dilemma lies in the many-to-one or many-to-few mapping processes, in such a case. Creating an exact matching cache may make the outcome more tragic, so tuning in a uniform way can be more human-compatible.Linux3.6 later. Removal of the support of the routing cache, all packets to be sent out, you must find the routing table. The current process may become the following logic
