This site has undergone a noticeable refresh to include a work page as a reflecion of my renewed commitment towards writing more about my work and learnings gleaned from my graduate studies, which I’ve embarked on since September 2022. 2022 was a productive year of change that took me away from the maintenance of this site, hence the lack of updates. But I intend to correct his by documenting the projects I’ve embarked on and the challenges I’ve faced along the way.
I love the new theme’s simple design that focuses on the site’s content. Migration of the posts from the previous theme and its visual assets was a breeze - altogether a fairly straightforward process which took less than 10 minutes.
The set up of Google Analytics was however a pain, and I wrote a short post on its set up here.
Today marks another major milestone for the Ubiquiti home network with the Fibre Termination Point (TP) finally installed! The OpenNet technicians decided to come two days before our scheduled appointment, but I was more than happy to accommodate to their request. I decided to relocate the TP from the living room to the service balcony to have it close to the network rack. Most households typically have the TP close to the TV consoles as it is common to use the router-modem provided by the ISPs, whom typically are the internet TV providers as well. The relocation involved drilling a new hole from the electrical riser into the kitchen to have a short run of cable straight to the desired location. I was initially quite nervous about the drilling as I didn’t want to puncture any pipes, but thankfully it went fine. All of the work was completed within 40 minutes but I was surprised that the task required a team of five men!
I’ve always wondered what makes up a digital file and Nicole Martin has wonderfully written a detailed post about the zeros and ones that make up a digital file.
I’ll briefly lay out the keys points from the post.
What makes a ‘digital’ file?
A digital file comprises of bits (zeros and ones) or plain text that contain crucial information that allows the computer/software to interpret/manipulate/process/encode/decode it into human-understandable information. The digital file may represent various types of information such as text, images and audio.
Programs can read plain text data without the aid of file signatures or headers (described below). Common types of plain text data include .txt and .html files. This has wide application as it is high compatible with most computer systems and software.
Binary data (zeros and ones) can represent more complex information and is read by computer programs in a linear data ‘stream’ or sequence of bytes. The program is required to decode the information block by block as per instructed by the file’s signature and header.
Useful info
Eight bits = 1 Byte
A set of 512 bytes is one ‘sector’ and ‘sectors’ may be grouped into ‘blocks’.
Parts of a file
File signature
It consists of a short section of code that defines the files format.
File Header
A sequence of data that instructs on how to interpret the information. Machines and software will follow the instructions in the header to process/interpete the data it contains.
File Body
The main bulk of information that allows the machine/program to render the file into human-understandable information. It can be stored as plain text or binary data.
End
The last section of code that signals the end of the package.
