Special Post-The Metaphor Behind Game of Thrones

Today, I watched Game of Throne S8E02. The war between the living and dead are imminent to break out and then suddenly, this episode ends, making me even want to insult the screenwriter. It seems the author or the screenwriter, more specifically, doesn’t want the audience to have a peaceful week and would rather let them eagerly to know the plot of the next episode. Here, I am very unhappy with the author’s bad tricks to lure the audience. So, hereby, I will talk everything to you. Everything, the plot of the next episodes and the true nature of the whole story and the fantasy world. Continue reading “Special Post-The Metaphor Behind Game of Thrones”

Use TensorFlow For Image Dection

I read about an article on Linux Developer &Users talking about TensorFlow. It gives you a whole view about the TensorFlow development process. In this manual the Inception V3 is used as an image classification model to classify various objects, from dogs to dinasours. It sounds pretty cool and I tried. The experience is both miserable and exciting!

The whole development process starts with finding an image classification neuton network.(of course, before that you have to install TensorFlow.) Then a new layer of neutrons is added to the model, so you can finely tuning the neutron network to make it customed to classify your new dataset, such as different breeds of dogs.( I love dogs, it is the only application scenario that I can think of .) Using your new data set, then you can retrain the last neutron layer. Afterd the network has snappy performance, you can then deploy the network to other platforms with TensorFlow installed. We can call this to be “put into production“. Continue reading “Use TensorFlow For Image Dection”

iptables, the formidable castle

iptables, the default firewall for Linux, is just like a castle. On one hand, it protects your from the invaders and make you safe, however, on the other hand, you often find yourself blocked by it and thus making your daily life annoying. Not only one time, you get frustrated by a service that is not working, until you think up the iptables which is still blocking the port. Another villain that can rival iptables is Selinux. They all make your system administration life more miserable. Securit, yes, but it comes with almost equal amounts of unconvenice and problems. Security and convenience in real life conflict with each other, thus, a compromise has to be found. The castle of iptables really have a high wall, a system administrator really has a the deep learning curve to climb. But here I will try my best to make you get a tight grip on this hard wall.

Realtek RTL8723B wireless card driver problem on Linux Mint

To get a feel about the most user-friendly linux distribution, I installed Linux Mint on my notebook. This notebook is manufactured by a small company in China under a brand name called Grefu. It carried a Realtek RTL8723B wireless card. Everything seems fine at the start, but quickly it loses connection to the wireless network. In the graphical desktop environment, everything seems good on the surface, but it just cannot get any signal on the scan. And it seemed the network adpter can‘t be brought up. The status bar of the adapator is always down. I once thought it may the problem of the NetworkManager and tried to bring it up in the terminal using command lines. But it still fails at last. And still I can‘t get any clue from the error logs. Eventually I googled the name of the wireless, until then I realized that it is the driver on Linux Mint just doesn‘t support this device, although it thought it can.

I found the solution on Github, where a warm-hearted developer write a module for it. See the link: Continue reading “Realtek RTL8723B wireless card driver problem on Linux Mint”
