I got a MacBook Air, Bosch drilling machine which ease my work, the angle grinder is also a great tool that made my day. Alhamdullilahi

Success in 2018 so is other years

2018 is one of the greatest year I will never forget. I learned a lot, to name some, Cisco (CCNA, ICND), OpenStack, Python, Adobe Premiere, DaVinci Resolve. I did enjoyed configuring PoE switches, configuring HP’s thin clients and Dell’s Wyse. I am doing some network installation which will continue to 2019. I am really enjoying what I am doing. I have nothing to say but: الحمد لله الذي بنعمته تتم الصالحات

Failure and Success in 2017

2017 is a great year like other years that passed. I did failed to execute a lot of projects, tasks I intended to do. But I also succeeded in many of my projects and tasks. I learned things that changed my like completely. I also understand that the most difficult thing in life is change, thus, changing from a habit to another it does take a huge amount of time.

I revisited POS software installation data entry plus more.

Patience is the antidote of every anger, with patience you can thrive to an unimaginable level. Being patient in everyday activity is going to help.

I pray Allah to help me in this new journey I embark, to help me fulfill all my good intentions.

2016 Year in Review

And how to install and configure CCTV camera, and run network cable and install faceplate successfully. Mastered some moves in Arabic calligraphy. Learn more about GPT partition system. Revisited scribus.

Opus Interactive Audio Codec

Opus is lossy audio compression file format developed by IETF (Internet Engineering Task Force) audio codec and stored in OGG container. It is used by real-time interactive applications on the Internet (VoIP, Streaming, web frameworks). Opus has an excellent quality, and at higher bit rates, it can compete with most notable formats like Vorbis and HE-AAC. Its quality is higher than that of HE-AAC codes.

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec.

Opus can handle a wide range of audio applications, including Voice over IP, videoconferencing, in-game chat, and even remote live music performances. It can scale from low bitrate narrowband speech to very high quality stereo music. Supported features are:

• Bitrates from 6 kb/s to 510 kb/s
• Sampling rates from 8 kHz (narrowband) to 48 kHz (fullband)
• Frame sizes from 2.5 ms to 60 ms
• Support for both constant bitrate (CBR) and variable bitrate (VBR)
• Audio bandwidth from narrowband to fullband
• Support for speech and music
• Support for mono and stereo
• Support for up to 255 channels (multistream frames)
• Dynamically adjustable bitrate, audio bandwidth, and frame size
• Good loss robustness and packet loss concealment (PLC)
• Floating point and fixed-point implementation
