Learning the Art of Electronics, Week 1 Week 1. Ohms law, power, Kirchhoff`s law V,I. Ohm`s law V=IR. So what is a Volt ? Potential energy per unit charge or work done to move a charge against electric field, form one potential to a higher potential. Dynamic resistance Rdynamic= ΔV/ΔI it is the local resistance – the tangent to the slope of […]
Learning the Art Of Electronics I have decided to get my self together and systematize my knowledge of electronics. It is very similar situation as for this guy. Electronics is my hobby. And actually one of many hobbies. I would say I have a lot of knowledge it but there are plenty of gaps and places just for intuition. Especially […]
Materialized view support in different DBMS Some notes regarding materialized view support in different database management systems. Materialized view is a database object that stores a snapshot of database query. If a regular database view could be seen as a “window” – one looks through this window and sees actual situation of the data, then “materialized view ” would be something […]
Reliacinė algebra ir norminės formos Kai kurie žymėjimai ir reliacinė algebra R={A1,A2,…,An} t.y, R yra lentelės L atributų aibė. Ai kur i=1,…,n yra lentelės atributas. Tada L(R) yra lentelės reliacinė schema. Lentelės eilučių aibę žymima l={e1,e2,…,em} kur n – lentelės stulpelių skaičius, m – lentelės eilučių skaičius. Kiekviena eilutė yra sutvarkytas reikšmių rinkinys ej = <a1,a2,…,an> ∈ l; ai ∈ […]
First design for 3d printer My first design for 3d printing! You can find it on a thigverse: https://www.thingiverse.com/thing:3560965 So that is why it might be a bit over engineered, bu hey, it is fun so who cares 😉 I had some hex type key for automatic yard gate engine disabling and it that plastic handle that got broken over time. […]

8086 disassembler using 64 bit assembly language 8086 disassembly application. Project done during computer architecture course. Project is done using nasm(yasm) 64 bit assembly and some c functions to handle input/output. I have chosen such technologies because I was curious about few topics: Learning about asm 64 bit programming Compiling assembly executable for windows 64 platform. During the comp architecture course we […]
