Here I will write down some of the notes regarding the some classes and books that I am currently taking/reading on computer science basics.

definitions

  • bit: a single unit of storage and can only store a boolean entity type of info (“0” or “1” / “true” or “false”). It can be physically be released as a NAND gate formed by two transistors. A particular arrangement of bits is called a state and an image is the literal physical configuration of these bits. For example in the upper-case letter A is a state, whereas the hexadecimal representation of A in ASCII configuration is 01000001 and this is the image.

  • boolean entity: a boolean expression is a logical expression between boolean entities such as on-off computer circuit elements, for example a NAND gate.

  • byte: collection of 8 bits. It can store the basic character in a computer like ‘2’ or ‘T’ etc.

-main memory: is the collection of bytes in a physical computer.

In experiments involving UHV chambers, there is always a necessity to observe a sample or a filament. In most cases, one can do this simply with a webcam, but in some cases, magnification is a must as the CF viewport could be far away from the sample. If sample orientation and movement is crucial as in most of the issues, one can use an implementation of a strong camera lens with a regular computer webcam. This type of ‘implementation’ always comes with a hard-to-solve issue of custom pieces to connect the two parts. Fortunately, there comes the help of 3D printing.

Using LabView with a Debian Distribution

So after 1 year of Windows 10, I again return back to Unix-like systems. Before the Windows 10, I used OSX and Ubuntu. I should say, I was happy but you can’t know how life treats you in the end. Anyway, now I got a new job that needs some LabView programming and further graphical programming skills, I wanted to install LabView to my personal computer. University generously provides licenses and needed *.iso files. But, I learned-a bit harshly- that, the package systems of CentOS, RedHat, Scientific Linux, SUSE are different than Debian, Ubuntu systems and National Instruments only support the early mentioned ones package system; *.rpm. So, I will going to make a short tutorial for the ones who wants to use the LabView in Debian systems. I think, this should also work for Ubuntu.
