    <content type="html">&lt;p&gt;NTIN060 (Algorithms and data structures 1) [tutorial] - big O notation, mostly just revision of last semester + small o notation, which to my understanding is like the difference between a maximum and a supremum (in a way i suppose..)&lt;/p&gt;&lt;br /&gt;&lt;p&gt;NMAI058 (Linear algebra 2) [tutorial] - determinant of a matrix, we solved a few and then came the &lt;i&gt;determinant olympics,&lt;/i&gt; something the teacher does every year, but only once every four it lands on the time of the winter olympics, one and a half dozen matrices (1/3 3x3 for 1 point each, 1/3 4x4 for 2 points each and the rest 5x5 for 3 points) whoever solved the determinant of a matrix first got the points.. i got 6 points placing me on a nice tied for 2nd place!! so i got a fidorka, which is a czech biscuit.. notable for being the one i got on Friday 2025-10-10 during NSWI120! if i had a nickel for every time...&lt;/p&gt;&lt;br /&gt;&lt;p&gt;NSWI177 (Introduction to Linux) - i am already pretty much introduced to linux as i use it on my main desktop since 2020.. also git, but i also know how to use that..&lt;/p&gt;&lt;br /&gt;&lt;p&gt;went to borrow an arduino for NSWI170, but the library was closed, then the train i was going to take home was cancelled/delayed idk it just said that i can use the following alternative trains instead and there was nothing, so i went to mcdonalds, got a fillet of fish burger, medium fries and an iced tea and ate and drank that at výstaviště and then went back to the train station and wrote this blog post&lt;/p&gt;&lt;br /&gt;&lt;hr&gt;&lt;br /&gt;koku daily message:&lt;br /&gt;silver medal&lt;br /&gt;&lt;br /&gt;&lt;img src="https://www.dreamwidth.org/tools/commentcount?user=kokulife&amp;ditemid=8825" width="30" height="12" alt="comment count unavailable" style="vertical-align: middle;"/&gt; comments</content>
