Last night, there was an announcements from apple. Mainly, they are all about the new iPhone, iPhoneXS. This times, there are three version, iPhone XS, iPhone XS Max and iPhone XR. They got the better screen than the last version, now, all of them use OLED now. And the iPhoneXS Max, the most high-end one, has 6.5" screen. Moreover, all of them got dual 12 Megapixels camera and A11 AI chip. That is much better, but the cheapest one is around $1629. That is too much for me. Moreover, there are no news regarding iMac Pro and Mac mini upgrade. I need one of those to upgrade my iOS development environment

When I got up last Sunday morning, I tried to turn on my mac pro which is a 2011 model. That is relatively old, but that is still in good shape. On that morning, it got me a black screen. It has a startup sound. I tried to press the keys randomly. It went to a forgotten password screen. I followed the instructions to reset my password. That still was not working. After a restart, that was still a black screen. Finally, I tried to use Control+Option+Command+Power, trying to reset NVRAM. It accomplishes this times. I believe for some reasons, the NVRAM saved the setting to dim the screen to a black screen.

I watched the keynotes of WWDC 2018, tag line is "Software Only". There are no new iPhone or Mac. I am disappointing, I am expecting there will be a CPU refresh for MacBook Pro,it switched to use the 8th Generation CPU. Only software update this year

A few weeks ago, I bought a Logitech G213 Prodigy Keyboard which is a budget gaming keyboard. It used a type of keyboard switch calls mech-dom. That is not a real mechanical keyboard. That is still membrane keyboard, but it can simulate the feeling of a mechanical keyboard. It has 4mm travel distance and 50g actuation force. These specifications are similar to Cherry MX red, and it has a feedback sound too. Moreover, there will have some anti-ghosting feature.
This is the reason to buy that to get the feeling of gaming keyboard without spending a lot. So far, I like that, but that sounds a better typing experience.

During the past few weeks, I have spent a few hours to upgrade my
Two laptops. Mainly, I have replaced the mechanical hard disk to SSD. Moreover, both of them are faster at least one times. My Mid-2012 MacBook Pro has a huge improvement. I have already upgraded the memory to 16GB before, but I still found that is very slow. However, after I upgraded the hard disk to SSD which is Samsung 850 PRO with SATA3. That is 6GBit per second bandwidth. Then I found that became a fast laptop. It can compare with a new mac book pro. I can use it to write apps. I am using Visual Studio for Mac in this book without any performance issues
