Lock-down pro-tip to save the battery of your car

Most cars (if not all) consume energy even when they are parked, with the engine off and no visible systems working. Electrical systems including the clock and on-board computer systems drain the battery little by little until they completely empty it.

When the energy level in a battery is low, it might prevent it from being capable to start your car and you will need a boost to get your car running again. In worse scenarios, batteries that are completely drained can get damaged and they need to be replaced.

Therefore, if you do not move your car for a long period (like during the lock-down period), then the extended lack of use might damage the battery and cause it to need replacement.

Simple Solution

Check the operation manual of your car or contact your dealer prior to disconnecting the battery. (We are not sure if there is a car out there that would not like having its battery removed)

Disconnect the battery from you car to stop the energy draining.
To do so remove the cable from the negative port (has the minus sign "-" and is usually black colored).

Do not let the negative and positive cable exposed metal ends touch under any circumstances.

This is an unprecedented global war, and mankind is facing the same enemy, the novel corona- virus. And the first battlefield is the hospital where our soldiers are the medical workers.
To ensure that this war can be won, we must first make sure that our medical staff is guaranteed sufficient resources, including experience and technologies. Also, we need to make sure that the hospital is the battleground where we eliminate the virus, not where the virus defeats us.
Therefore, Jack Ma Foundation and Alibaba Foundation have convened a group of medical experts who have just returned from the frontlines of fighting the pandemic. With the support of The First Affiliated Hospital, Zhejiang University School of Medicine (FAHZU), they quickly published a guidebook on the clinical experience of how to treat this new coronavirus. The treatment guide offers advice and reference against the pandemic for medical staff around the world who are about to join the war.
Thanks to the medical staff from FAHZU. While taking huge risks in treating COVID-19 patients, they wrote down their treatment experience day and night in this Handbook.
Over the past 50 days, 104 confirmed patients have been admitted to FAHZU, including 78 severe and critically ill ones. Thanks to the pioneering efforts of medical staff and the application of new technologies, to date, we have witnessed a miracle. No staff is infected, and there is no missed diagnosis or patient deaths.
Today, with the spread of the pandemic, these experiences are the most valuable sources of information and the most important weapon for medical workers on the battlefield. This is a brand-new disease, and China was the first to suffer from the pandemic. Isolation, diagnosis, treatment, protective measures, and rehabilitation have all been started from scratch, but we hope that with the advent of this Handbook doctors and nurses in other affected areas can learn from our experience when entering the battlefield and they won’t have to start from zero.
This pandemic is a common challenge faced by mankind in the age of globalization. At this moment, sharing resources, experiences and lessons, regardless of who you are, is our only chance to win. Because the real remedy for epidemics is not isolation, but cooperation.
This war has just begun.

Hikvision DVR sending email over GMail

Recently, we were trying to setup the email configuration of a Hikvision DVR which even though it was updated to the latest firmware we would get the message Testing Failed when trying to send an email over GMail.

In the GUI of the DVR there was an option to Enable SSL but no option to enable TLS/STARTTLS. So after consulting the GMail official documentation on how to configure an email client for GMail, we set the SMTP Port to 465 and enabled the SSL option. Then we created an application password for the DVR and tried to test the settings. To our disappointment we got the Testing Failed message.

After reading the latest user manual of the DVR, it mentioned an option to Enable SSL/TLS but not Enable SSL which got us curious. It raised the following question to us: “What if they enabled the TLS functionality but they forgot to update the GUI to match it?”. So we changed the port to 587 and hit Test again.

Guess what ?

It worked!!

It appears that Hikvision enabled the TLS/STARTTLS functionality but forgot to make their GUI reflect the change!

Using the settings depicted in this photo, we were able to send test messages from our Hikvision DVR over GMail using TLS/STARTTLS on port 587 of smpt.gmail.com!
The confirmation of the successful email sending operation.
“TESTING SUCCEEDED.”

Coronavirus disease (COVID-19) Myth busters!

We also hate false facts, so in an attempt to help spread the correct word on COVID-19 we are reposting the myth busters for the common false COVID-19 myths.

From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
There is no reason to believe that cold weather can kill the new coronavirus or other diseases. The normal human body temperature remains around 36.5°C to 37°C, regardless of the external temperature or weather. The most effective way to protect yourself against the new coronavirus is by frequently cleaning your hands with alcohol-based hand rub or washing them with soap and water.

Taking a hot bath will not prevent you from catching COVID-19. Your normal body temperature remains around 36.5°C to 37°C, regardless of the temperature of your bath or shower. Actually, taking a hot bath with extremely hot water can be harmful, as it can burn you. The best way to protect yourself against COVID-19 is by frequently cleaning your hands.

To date there has been no information nor evidence to suggest that the new coronavirus could be transmitted by mosquitoes. The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water. Also, avoid close contact with anyone who is coughing and sneezing.

Thermal scanners are effective in detecting people who have developed a fever (i.e. have a higher than normal body temperature) because of infection with the new coronavirus. However, they cannot detect people who are infected but are not yet sick with fever. This is because it takes between 2 and 10 days before people who are infected become sick and develop a fever.

No. Spraying alcohol or chlorine all over your body will not kill viruses that have already entered your body. Spraying such substances can be harmful to clothes or mucous membranes (i.e. eyes, mouth). Be aware that both alcohol and chlorine can be useful to disinfect surfaces, but they need to be used under appropriate recommendations.

No. Vaccines against pneumonia, such as pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus. The virus is so new and different that it needs its own vaccine. Researchers are trying to develop a vaccine against 2019-nCoV, and WHO is supporting their efforts. Although these vaccines are not effective against 2019-nCoV, vaccination against respiratory illnesses is highly recommended to protect your health.

People of all ages can be infected by the new coronavirus (2019-nCoV). Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus. WHO advises people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.
