33rd: "Delete: The way of big data trade-offs"

The book was added to the reading list after the Big Data era, and I wanted to see how the author kept only the most useful megabytes of photos from a few gigabytes of photos, and later found the Kindle ebook, to try it out, to tell the truth, the book was quite verbose, repeating "forgetting" and "remembering" back and forth. These two words constantly emphasize that the default state of the human being is forgetting, not remembering. For this kind of book method, the use of fast reading skills, I also read fast, also the title of the "delete" technique, a large section of the paragraph to skip, only a few scattered a little inspired sentences. The experts who study "data privacy issues" can slowly understand his point of view.

For human beings, forgetting has always been the norm, and to the present time, memory has become the norm, a lot of things have digital traces, want to forget is not too easy. Digital technology has made society lose its ability to forget, and instead it is a perfect memory.

When you leave a gossip on today's web, and this sentence has been kept longer than your lifespan, do you dare to express your opinion casually? The electronic footprint you stay on the web will likely hurt you someday. is your blog, Twitter, comment or a web name likely to hurt you, including this short reading note?

"There is a good chance that a third-party device will not only be able to get a complete digital memory of where we are, but also to have digital memories of when and how we interact with the things around us," the book says. Doesn't that mean a wearable bracelet or a watch?

Perfect digital memory may lead us to lose an important human ability----the ability to live firmly in the present . If we do not have the ability to forget, then every time we face a choice, we tend to recall all of our past choices, which may cause us to hesitate.

In the age of big data, it is also necessary to find ways to make certain information have forgotten function. The author puts forward several ideas in the last chapter, but now it seems that it is not easy to do so.

Let things remember the evolution of history, from verbal legend, painting, text, books, to the current digital information. Before the various information in a number of copies will have the noise of the addition or loss of quality, and now the digital age to avoid the addition of noise, millions of times after the next, is still the file, the exact file.

Once a person has shared the information, the person basically loses control of the information.

Information extraction may be taken out of context, because in the process of extracting information, a lot of information is removed, or the context is changed, although it may take enough time to find the source of a paragraph, in the big data age, it is no longer possible to find the source of a piece of information.

Digital traces make "a person's life has a certain meaning", because the use of digital memory, even if one day we died, our thoughts, feelings and experience are still not lost, still can be used by future generations. With these, we can continue to live and escape the forgotten destiny.

Forgetting has become expensive and difficult, but memory is cheap and easy. The capacity of the U disk is getting bigger and cheaper!

It's also bad to keep a detailed email or log in the past: when you look up a person's information, the result is an unpleasant experience long ago, and it's almost nonexistent in your mind. But these external stimuli have helped us reactivate those negative memories that have been forgotten.

Given a time in the past, it is very difficult for a human to think about what happened that day (but for a major event is an exception, such as 911), so time is a very difficult memory dimension for human beings.

The author puts forward a point of view, in order to let the digital system have forgotten function, to the file storage system to set a storage period, the file will be destroyed by itself.

See the DRM system, check it, the English full name Digital rights Management, refers to the management of copyright, but it seems not very successful.

In the big data age, some big companies seem to have a weak side too, and Google keeps a lot of information, but if Google abuses personal information, it will be the end of the day if you lose trust in Google. From this book, it turns out that Google has saved only 9 months of user search records from 2008, and later to obfuscate the information.
