 <span>My first attempt to find an internet café, which was working during Christmastime, failed. However, I found with my N95 phone lots of free WLAN hotspots. The hotspots refused me logging into my server using SSH as I have configured a non-standard port for SSH for security reasons. Without knowing the costs, I used the GPRS internet access of my German phone provider (yes, I had to pay roaming fees). </span><br />

 <span>DTail does not aim to replace any of the log management tools already available but is rather an additional tool crafted especially for ad-hoc debugging and troubleshooting purposes. DTail is cheap to operate as it does not require any dedicated hardware for log storage as it operates directly on the source of the logs. It means that there is a DTail server installed on all server boxes producing logs. This decentralized comes with the direct advantages that there is no introduced delay because the logs are not shipped to a central log storage device. The reduced complexity also makes it more robust against outages. You won’t be able to troubleshoot your distributed application very well if the log management infrastructure isn’t working either.</span><br />

 <span>As a downside, you won’t be able to access any logs with DTail when the server is down. Furthermore, a server can store logs only up to a certain capacity as disks will fill up. For the purpose of ad-hoc debugging, these are not typically issues. Usually, it’s the application you want to debug and not the server. And disk space is rarely an issue for bare metal and VM-based systems these days, with sufficient space for several weeks’ worth of log storage being available. DTail also supports reading compressed logs. The currently supported compression algorithms are gzip and zstd.</span><br />

It is up to the client software how your capsule looks. For example, you could use a graphical client, such as Lagrange, with nice font renderings and colours to improve the appearance. Or you could use a very minimalistic command line black-and-white Gemini client. It&#39;s your (the user&#39;s) choice.</span><br />

You can ensure that things stay efficient and straightforward as long as you are using the Gemini protocol.

I didn&#39;t love the syntax, especially the indentations used; they always confused me.

 <span>This book was recommended by my brother and also by at least another colleague at work to be one of the best, if not the best, book about Java programming. I read the whole book from the beginning to the end and immersed myself in it. I fully agree; this is a great book. Every Java developer or Java software engineer should read it!</span><br />

 <span>I have tried many note apps for my Android (I use GrapheneOS) phone. Most of them either don&#39;t do what I want, are proprietary software, require Google Play services (I have the main profile on my phone de-googled) or are too bloated. I was never into mobile app development, as I&#39;m not too fond of the complexity of the developer toolchains. I don&#39;t want to use Android Studio (as a NeoVim user), and I don&#39;t want to use Java or Kotlin. I want to use a language I know (and like) for mobile app development. Go would be one of those languages.</span><br />

With Fyne, the app can be compiled easily into an Android APK. As of this writing, this app&#39;s whole Go source code is only 75 lines short!! This little tool is designed for spontaneous moments,
