Keep your Data out of Hackers' Reach!

Below are some simple practices that you may adopt to keep your valuable information and data out of hackers’ reach.
  1. Safeguard your computers
    • Secure your computers with anti-virus software.
    • Keep virus signatures, spyware signatures, Windows and other software patches updated.
    • Enable personal firewall.
  2. Securely protect your smartphones and tablets
    • Lock your smartphones and tablets by enabling passcode and automatic screen lock after a short period of inactivity.
    • Avoid storing confidential / sensitive data on your smartphones and tablets.
    • Securely erase / wipe all the data in your device before discarding or selling your device.
  3. Set Strong passwords
    • Enable password protection for all your computing devices, smartphones and files (e.g. Excel and PDF files) containing confidential information.
  4. Avoid sensitive data transmission
    • Do not post or transmit any files containing sensitive data over the Internet. If you have to, send them in encrypted mode.
  5. Always use Encryption when processing sensitive data
    • Email: Protect the message content from being read by anyone other than the intended recipient. This requires a digital certificate. 
    • VPN: Establish a VPN connection when using Wi-Fi service.
    • Web browsing: Use SSL (https://), whereas appropriate, when browsing any website that may process sensitive data.
    • Files and Folders: Encrypt files containing sensitive data with encryption software and strong password.
  6. Do not open any suspicious emails.
  7. Never disclose your password
    • Remember that the University will never ask you to confirm or validate your email account, password and personal information by replying to an email or by clicking a hyperlink in the email. If you suspect your CWEM password is disclosed or computing device is being hacked, you should change your password immediately and report it to ITSC.

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved  from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

    14 Oct 2020,  being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station.   The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station.  previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
