Although I know that being unhappy all the time is not good, I really didn’t feel much better today.Frustrating software, from installation in the morning to afternoon. Various issues, not enough memory, which is of course a problem with my computer. I’ve been criticized by my junior, but what can I do? My computer has also had a tough time, costing less than five thousand, and it’s been six years. With less than a thousand spent each year, what more can I ask from it?To solve the memory issue, I found that the solution was to only install Matlab and nothing else. With just over 4GB, it was manageable. After finally getting it installed, luckily my junior has a Baidu Cloud membership, which significantly sped things up. Later, when I tried to download the installation package myself, I realized the difference in speed between having a membership and not having one is like heaven and earth. So, I reluctantly bought a trial card to speed things up. After installation, I encountered a license expiration issue when opening the software. I tried all the online guides, but none worked.By chance, I saw a warning about version 2024b, and it turns out many people had issues installing this version. So, I started looking for resources again, using browsers and Zhihu. Each time I downloaded and started the installation, I either faced license issues or other problems, and in the end, the software failed to install, and my remaining memory was almost gone.I really was just creating problems for myself, so I decided to delete the installation packages. Finally, I found version 2023b and its installation tutorial on Bilibili. Seeing all the comments filled with thanks and praise, I was initially skeptical because I had seen many similar comments during my previous failed installations. Unexpectedly, it actually worked for me. I immediately went to the comment section to express my gratitude; that person is truly a great help.In the afternoon, I worked on simulations, which actually don’t seem too difficult at the moment, just a lot of parameters. Teacher Wang checked each one carefully; she was very gentle today, I wonder if it’s because she has a cold. But she really catches colds easily. I need to take care of my health too, but my own sleep isn’t great either.I couldn’t make it to the gym today, so my squats will have to wait until tomorrow.In the evening, I told my mom that I couldn’t sleep. She suggested taking some medicine. I said I didn’t have this problem before I turned twenty-four; why is it starting now? My mom replied, “This is just the beginning; wait until you’re in your thirties or forties, then you’ll really have sleepless nights.”It was really hot today, and I didn’t know what to eat, so I rode my bike out. I went to eat dumplings, which were just okay—not very delicious, but there were a lot of people there.Well, let’s just leave it at that for today. Time to clock out. I still need to take a shower when I get home.
