Coronavirus – Wear your Face Mask Properly

Let’s take a break from tech and address more serious matters today… the spread of coronavirus. So if you need to wear a face mask, what is the correct mask to wear and how to wear it properly? I decided to do some research and this is what I gathered

OK this is the typical mask most people wear. It’s a surgical mask which has a “white” (lighter) side and “blue” (darker) side.

Apparently this is the most common version floating around…. The white side has the filter. If you are well and don’t want to breathe in germs/polluted air, wear the mask with the blue side inwards and white side outwards. If you are unwell and don’t want to spread your germs to others, wear the mask with the white side inwards and blue side outwards.

However a more recent version is that there is only one correct way to wear your mask, that is the blue side (the side with the downward folds) has to face outwards. Most surgical masks have 3 layers, the blue (outer) layer which serves to repel fluid. The middle layer is a barrier to germs while the inner layer absorbs moisture. Apparently the purpose of the blue layer is to prevent germs from sticking onto the mask. But if you wear the mask with the white side facing out, air moisture will stick on it and make it easier for germs to stick around.  More info >>

Searching around, I found that Hong Kong’s Centre for Health Protection has a good and detailed explanation in support of this. Download the document here >>

So what about N95 masks, do they help? Apparently not, according to Singapore’s Health Ministry which is advising the general public to wear normal surgical masks instead of N95. Normal surgical masks are more practical and helps block large particle droplets from entering your mouth and nose. However N95 masks are tight fitting and designed to filter small airborne particles. If worn properly, it makes breathing difficult. If not worn properly, you are not protected from the air particles anyway. More info >>

 

How to Speed Up Your WordPress Site

Recently I finally took the step to update my WordPress theme to a mobile responsive one. While in the process, I decided the main criteria would¬† be loading speed, which explains why I ended up with this basic looking no-frills theme. Yep this is the stock standard WordPress “Twenty Nineteen” theme which is clean and no-nonsense. At the same time, I installed an SSL (using free cPanel SSL) and used the Really Simple SSL plugin which automatically detects and configures all my settings to run in https.

While doing this, I recalled a recent PHP Upgrade I did for a client from PHP version 5.4 to PHP version 7.1. It seemed to have worked well for his WordPress website so I thought I’d do the same for this website. After that I ran Optimize Website in cPanel (look for it under the Software section in cPanel).

The result in Google PageSpeed Insights has been astonishing. Checking it just now, I scored 98 points for both Desktop and Mobile View! If you find that hard to believe, so do I. In all my years doing website development, I’ve never ever come close to this score.

So hopefully these screenshots will convince you:

Now we all know that Google PageSpeed Score is not perfect. And it’s not the be-all-end-all in website speed testing. However just making these small tweaks make all the difference. Of course, you first need to have done some basic things like optimizing your images, signing up with a good web host in a good server, avoiding slider animation and CDN content delivery if possible.

 

Adobe Flash Player Update keeps popping up in Mac after Uninstall

Adobe Flash has been on a massive decline in recent times. Due to security concerns, tech leaders such as Google, Microsoft and Apple have exited in doves by phasing out Adobe Flash support in their products.

Recently out of curiosity I decided to install Adobe Flash Player. Around 2-3 weeks later I noticed a popup asking me to update Adobe Flash Player. I closed the pop-up but a couple of hours later it popped up again. The popup became more frequent (less than one hour apart). So I went to System Preferences and removed Adobe Flash Player. But this is not the end of the story. The annoying pop up continued even after the software was removed.

After some searching around, I found a simple solution. Go to Applications – Utilities. You will see a file called Adobe Flash Player Install Manager. Just delete it and the annoying pop-up should stop.

Note that Adobe will no longer update or distribute Flash Player effective end 2020.

Everybody knows Google, the most famous search engine on the internet. You can search anything on Google. When your friend ask you something that you didn’t know the answer, you would easily say, lets Google it. Google also is the developer for Android OS, the operating system for smartphones. The latest invention by Google is the Google Glass, the unique glasses that can almost do whatever you want. But is there anything else that Google has created beside all these inventions?
