With the popularity of Internet language, we will also contact a lot of "Martian" and rare words in the office, using these words, although very interesting, but in the input is very troublesome, in fact, do not need to tangle, now directly use Word Three steps can be done.

Use Excel to remove the soft return, there is a description on the Internet, no longer repeat here. This article only describes how to use EditPlus to delete a large number of soft carriage returns contained in text.
When a CSV file is imported into the database, if it contains a soft return, sometimes an error occurs, causing the import process to break. We look at these texts in UE and we may see completely normal content. For example, in Excel, a cell is entered:
The opportunity is
0.5% of the patients in our screening program are suffering from cancer. In this case, the error rate of 1% is no longer as good.For example, here is a line of code that ignores the input value x, so that y is always equal to 0, so it always predicts that no one has cancer. Then this algorithm actually has only 0.5% error rate. So this is even better than the 1% error rate we got before, which is a non-machine learning algorithm because it just predicts that Y is always equal to 0. is very smal
is still supported, but the features are different from those before ...... In this case, an error is not reported, and you need to go deep into the code logic.

A beautiful dream is the same as a beautiful poem. It is a rare and unpredictable dream that often appears at the most unexpected moment.
I like such a dream. In my dream, everything can start again. Everything can be explained slowly, and I can even feel it in my heart, all wasted time can return to the ecstasy and gratitude of the time, with happiness in your mind, just because you are in front of me, smiling at me, just like that.

use semantic-meaningful names for type names instead of language-specific keywords. For example, the name getlength is better than getint. In rare cases where the semantic meaning of an identifier is limited to its type, the common Common Language Runtime Library (CLR) type name should be used instead of the language-specific name.
For example, the method for converting data to int16 should be namedToint16InsteadToshortBecauseShortYesInt16Language-sp

However, I once again stressed that calling GC is only for testing. In actual products, calling GC is basically meaningless (except for controlling GC timing). In short, if your program has a memory leak, it must have nothing to do with GC, do not waste any time or energy in such a place.Automatic GC is triggered only when the memory is applied.
The GC of avm2 is triggered based on the current memory usage each time the memory is applied. Memory application is a necessary factor. Therefore

Looking at my self-built dual-core computer, it is rare to feel the refreshing usage of the computer's performance improvement. Of course, based on my experience, this feeling disappears after a maximum of one week, and then begins to lament that the system is slowing down. however, I think back to the computer with a processor clock speed of only MHz, which is full of memories. as a result, I have developed a lot of old software that can be stored, s
