Also known online as jieggii ([dʒɪˈjɛɡʲɪ]).
I study ICT at Metropolia University of Applied Sciences in Helsinki, and work at Uncle Alex Travel and Zontiq Labs.
In my spare time I do a variety of things — some of which I would like to share on this web page. Subscribe if you would like to follow along.
Me and my friend have been recently moving to a new apartment. On the moving day we were walking back and forth to carry our stuff from the car. During one of such trips, passing by a trash point, we noticed a large TV there. It looked surprisingly good, and the screen was not shattered. Of course, there was a tiny chance that someone would have thrown away a working TV. However, some minor software or hardware issue might have taken place, and the owner just didn’t bother fixing it. ...
I made a bunch of shots and frankly did not know which one to share, because all of them turned out much less impressive than it was in real life. When I watched Saturn with my actual eye through the eyepiece, the image did feel unrealistically sharp! It was rather small, but I was able to see the rings and the planet itself, as well as some smaller details. However, attempts to capture it with the smartphone camera turned out to be somewhat of a disappointment. ...
In the evening of August 12, many curious people around the world including me observed a solar eclipse. Egor with the box. Unfortunately I had no possibility to travel to Spain, Iceland or any other better observation location to witness the total eclipse, so I viewed it in Helsinki where it was partial — around $80\%$ coverage (which is anyway pretty impressive). Camera obscura (aka Pinhole camera) Frankly, I should have prepared better. The thought “wait a second, wasn’t there a solar eclipse soon?” came to my mind only in the evening on the day before the event. ...
I’m excited to announce that I added comment functionality across the site on jieggii.cc using Remark42. A warm thank you to Umputun, the maintainer of Remark42, and its contributors — the tool is perfect for the task. It was straightforward to set up thanks to the clear documentation. I plan to add more social login options over time. At the moment of publication, only Telegram login is supported. Feel free to leave your test comments below!
I finally got to try my new phone-telescope adapter. It turned out to be one of the best affordable upgrades I’ve made. Since I was outside before dark, the only visible target was the Moon. Hardware The same affordable setup as in previous sessions plus the adapter. Newtonian reflector telescope (130/900) 25mm and 10mm eyepieces (default ones, came with the telescope) 25% Moon filter – reduces incoming light to 25% to prevent glare Built-in iPhone 15 camera Smartphone adapter Software Halide App (camera app) – I used this third-party camera app; however (possibly due to limited photography experience) I found no difference in quality between photos taken with this app and the default camera app. Default Photos app – used it to slightly adjust colors to improve contrast and to crop. Additional Resources Interestingly, Google has Google Maps for Moon and other space objects. More details can be found on Google Maps Help. ...
I’ve recently been adopting RSS feeds into my everyday life. If anything or anyone I’m interested in has an RSS feed, I find and subscribe to it. However, there are a couple of email newsletters I follow, and unfortunately they don’t have any alternative way to subscribe to them – only occasional messages appearing in my inbox. For me email inbox has mostly been associated with: messaging with someone having some temporary receipts or tickets there having letters regarding account updates on some online platform The email client doesn’t feel for me to be the right place for the content I want to read. The content I want to read belongs to book apps, RSS reader apps, browser, Telegram, X or some other app, but definitely not the email app. ...
Well, that was quite a year! This year was much more than I expected. It was much tougher than I expected; however, it brought much more knowledge, joy, and skills. People The amazing people I had the great luck to spend this academic year with: teachers, classmates, students from the parallel classes, others on campus, and even people from other universities and fields I met at various events. The level of support, understanding, and this feeling of all of us being in the same boat… That is unforgettable. ...
For the past year, I’ve been building the tool we wished existed for our tour business. Running a tour operator business is chaotic, especially in the beginning. Bookings come from multiple sources: online platforms (Viator, GetYourGuide, etc.), direct website sales, manual requests, and partners. It quickly becomes a real operational headache: you need to aggregate bookings, plan pickups, notify customers, and coordinate drivers. Existing tools like Bókun and Rezdy solve many problems — and that’s exactly the issue for small tour operators. Those systems try to be everything for everyone: overcomplicated interfaces, features that aren’t useful, expensive monthly plans, and often an extra 1–3% fee on every booking. ...
