On the difference between fast and slow Internet speeds With the popularity of the Internet, users pay more and more attention to the speed of response. The faster the website, the higher the user stickiness and conversion rate. To put it simply, it means increasing the speed! There are many factors that affect website speed, such as…………………. Being serious is not my style, please watch my performance below Origin of the idea: The initial idea was to use pure CSS to implement it. Base64-encode the base image and place it directly on the background-image, so that the background image can be loaded together with the web page. ...

One life creates two, two creates four, code creates all things… The world created by programmers provides more possibilities for human beings It’s the annual 1020 Programmer’s Day again. No matter how busy I am at this time of year, I will write an article on time. I didn’t write any open source projects this year, but I also wrote a lot of code, which could circle the earth twice. 2020-1024=996? ? 996, which caused a lot of commotion last year, was this destined to happen? There seems to be no good copywriting to share with you this year. . Then let us program for ACG~~! ...

I have always had a wish to buy VR equipment, and today it finally came true I bought an Oculus branded VR all-in-one machine on the recommendation of @本集团马竞技 Open a money-saving card -> receive coupons -> top up money -> place an order -> done in one go (heart is bleeding) Since the Oculus brand has not entered the Chinese market and other reasons, I also bought a Gigabit router bundled with it. It arrived in two big boxes One is equipped with the VR body, and the merchant gave an extra USB rechargeable battery, SMARTOOOLS Spanish brand, which seems to be OK The other box contains my Gigabit router and hundreds of USB3.0 link cables A router that looks like a peanut shell A bunch of incomprehensible instructions, and it’s still an external fan (#cryLaughter). Since this router brand is also foreign, the three-wire plug is European standard, and domestic three-hole sockets need to be connected to a converter. Outer packaging - on the reverse side, there are some popular game recommendations below Front, simple and cool The box inside the package is printed with the Oculus logo. Lift the lid, wow Oculus Quest six degrees of freedom VR is currently the most powerful all-in-one VR machine on the market Officially, it comes with a pair of handle batteries, a basic operating manual for the device, and a thick manual that is too detailed to be understood. Posing, host + left and right handles The next step is to turn on the phone and download the Beat Saber and VRChat that I have been thinking about for a long time… to start my journey of escaping reality… ...

Become CEO, marry Bai Fumei, and reach the pinnacle of life. The first step is to buy a server A server with a graphics card Motherboard Memory module CPU fan Hard disk + CPU Then some small parts arrived one after another, such as power cords, network cables, meters, etc. When the things are almost there, we start assembling and turning on the power. The keyboard, monitor, and installation USB flash drive are all borrowed, and they must be returned after turning on the computer. The boot process was not very smooth and it took two or three weeks before it started running normally. In order to deal with power outages and shutdowns when no one turns on the phone when a call comes, I bought a WiFi remote boot module, which automatically turns on the phone when the call comes. Later, in order to deal with the power outage, we directly purchased a brand new UPS, which has power outage protection, continuous power supply, stable voltage, and protects the server. Later, because the configuration could not keep up, we purchased a new CPU and new graphics card New motherboard Finally put it into the special chassis This may be the server you use with tens of millions of data (-laughing The server has been running normally and uninterruptedly for several months.

I finally have time to post a blog. This Dragon Boat Festival was not wasted. Our team went to Shuangyue Bay in Huizhou City for a pleasant trip of 2 nights and 3 days. I won’t give an overview of the bumpy journey on the road….. Shuangyue Bay Observation Deck, after finishing the breakfast provided by the hotel early in the morning, we set out to the observation deck overlooking the entire Shuangyue Bay. I rode a small yellow car and walked freely through the traffic jam, and soon arrived at the foot of the mountain. Since there were many people at the Turtle Museum and we didn’t wear masks, we skipped this attraction and went directly up the mountain. After climbing for several hours, we finally reached the top of the mountain Like two opposing crescent moons Isn’t the scenery at the bottom of the mountain beautiful? Mei, why are you spending so much time here? For snorkeling at Xiaoxingshan, rent a boat, go out to sea together, bring your equipment, and dive into the water. ……… Wearing a lifejacket, a lifebuoy, and holding on to the lifeguard, I really can’t dive in… Gagaaaaaaaaaaaaaaaaaaaaaaa The water near the islands in the far sea is indeed much clearer than the shore The reefs on the side may be called rocks. It reminds me of Mio Akiyama in “Light Voice Girl”. It’s so scary when you look closely…ah…ah Return at sunset and enjoy the sunset over the sea From time to time, I take a sip of sea water, wow, salty, bah bah bah. The water drops are beating In the evening, abalone and lobster are served We call it, Abalone and Lobster Bureau, as if you can hear the sound of your wallet bleeding. Suddenly I realized that I forgot to take a picture of the night scene, it was over… ...

618 do not buy something always feel sorry for themselves. Xiaomi because of Mi fans. Always believe that good things are about to happen I’ve always wanted to buy a watch to watch the time before, just in time for the debut of the Xiaomi bracelet 5, and then I gave it a second! I’m not going to be able to get a lot more than that. The entire package is relatively monotonous, there is nothing to see. The actual fact is that it’s not a good idea to have a good time with the company. The bracelet seems to be unable to turn off the phone, once you bring it to tap the home button, it will show up. I’m not sure if it’s a good idea, but it’s a good idea. After the binding, a messy upgrade First start Change to a cute theme Then there is nothing to introduce, the function and so on can be on the official website to see, why do I have to introduce it? The summer, hands bare, always have to stay something right

In 2020 I want to develop a new interest. Some time ago I was watching “Sound the Sound!” Euphonium", so much so that I had to read it even if I borrowed it from someone. Then I was deeply touched by Kumiko. The process from being indifferent to everything to wanting to work hard for this deeply inspired me. As for me, I may be just like Kumiko. I have lived an ordinary life since I was a student. Everything does not matter. I have never struggled for a certain thing. No matter how big the world is, it has nothing to do with me. ...

Cause Last week I was working on the factory push feature for Android, and certain models could not be factory pushed offline, so I was ready to unpack the apk to see if something was wrong with the packing parameters. Preface. In Android development, we may need to jump from our own application to another application’s interface, but in the case of not knowing another application’s package name as well as the class name, it is very difficult to do this, there is a simplest way is to download the application’s apk file, and then change the extension name to zip or rar, and then unpack the file afterward, in the unpacked file, there will be a AndroidManifest.xml file, but after opening, it may be garbled, which is embarrassing, how to do? ...

As the name suggests, face-to-face payment helps merchants achieve quick collection in offline consumption scenarios; face-to-face payment products support two payment methods: barcode payment and scan code payment. What we connect here is scan code payment. Scan code payment refers to a mode in which users open the “scan” function in Alipay wallet, scan the QR code displayed by the merchant in a certain cashier scene, and make payment. This model is suitable for offline physical store payment, face-to-face payment and other scenarios. The business process is shown in the figure below: Since signing a contract with face-to-face payment is very simple, individual industrial and commercial households/individual merchants are allowed to sign a contract. Therefore, this method is also widely used for online QR code payment. Since this method violates the relevant terms of Alipay, it has certain risks. As a technical exchange, we will put this issue aside for the time being. ...
