Nikki's Lunch

 This is what I heard from my junior after he moved to a different company. They found an issue with data transfer cost due to internal ALB and NAT Gateway in the same subnet. Apparently, the internal application sends data to the ALB and it's being processed by the NAT gateway as well. I'm not exactly sure how it works, but it was a bad networking. They removed the NAT gateway and just let the ALB managed the traffic and save cost. 

 Ok, this is a rookie issue. I had virtual environment created, activated and the package installed for that virtual environment, but somehow I bumped into this error: Import could not be resolved [Pylance] Turns out to be the interpreter is pointing to the wrong one in my VS code bottom right. Changing it to the one in virtual environment fixed that.

 I have Python 3.12 installed on my Windows 10 machine. I tried to install a package using Pip. Apparently, the package contains Cython and needs to be compiled. However, the compilation failed with the following message: Cannot open include file: 'io.h': No such file or directory Ok, not a problem, I just go to Visual Studio Installer and install Desktop development with C++ package. That fixed the first issue. But installing the package still failed. This time the error message is: 'C:\\Program Files\\Microsoft Visual Studio\\2022\\Community\\VC\\Tools\\MSVC\\14.41.34120\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2 To fix the above, I had to downgrade python to 3.10 and the package is installed properly.

 Most of the time we have to type fast, especially in today's world where speed is life. So, we are bound to mistype. In Linux, one of the commonly used command is "ls", so to "train" user to correct that, an "sl" command is created. SL stands for Steam Locomotive. Check it out in your Linux distro, search, install, and run the command and it will show a moving locomotive.

My outlook somehow keeps reminding me on old meetings that occurred weeks before. Dismissing all or each one doesn't work. It keeps coming back. I tried the suggestion to remove cache, clear reminders and none works. Finally, the only one that works for me is to open up the details of each one of the old meetings from the reminder and then dismiss them. They never showed up in the reminder ever since.

 I was looking for a budget friendly way to receive email on my custom domain. So, let say, I own example.com and I want to receive email on receive@example.com.  As I did my research, I found various way on doing it: Just forward it . My domain name vendor apparently comes with free email forwarder, so I forward it to my non-custom domain email such as gmail. Just forward it (DIY) . This is also a very cheap alternative and low cost. One way is to forward it through AWS SES. One such project is:  https://github.com/arithmetric/aws-lambda-ses-forwarder Receive it through hosting . I thought about this especially when I already paid for hosting service, usually it comes with mail server for free. Of course, we can always subscribe to some email service, but it will cost more but it has more features too.

 I have an old Samsung Galaxy Note 4 that was not turning on for a long time now. Out of curiosity, I read about it came back to life by putting it in the freezer, so I gave it a try. I took out the battery, put the phone in a ziploc bag and put in the freezer for at least 8 hours (so I can sleep or work through it). I also make sure the battery is charged separately since I have a battery charger. After 8 hours, I take it out, put the battery in, and surprised that it turns on. However, it won't turn on anymore after I turn it off, so I placed it into the freezer the second time and it works again. My guess is the freezer probably takes some humidity out from the components and allows it to work better.

 I finally got some time to get back to mobile development after many years. And Android has a new way to create an app with Jetpack Compose. At a glance, it is amazing, I managed to create a complex app much faster than using XAML, yep, you read that right, that's how I used to do it. All is well until I encountered infinite loop when trying to remove item in a mutableList displayed using LazyColumn on a button click. Basically, the button click somehow causing a recomposition and then the recomposition retrigger the button click event again and again. But it only happened when I remove an item, adding an item is fine. Here's the example of initial code: data class Pet(var timestamp: Instant, var name: String) @Composable fun Screen() { val pets = remember { mutableStateListOf<Pet>() } fun addPet() { pets.add(Pet(Clock.System.now(), "Pochi")) if (pets.count() > 5) { pets.removeAt(0) } } addPet() ...
