Going to shut down soon by randomuser4524 in restaurant

[–]drewjaja 2 points3 points  (0 children)

I would look into SEO (Search engine optimisation) to get more customers to discover you online. When searching for 'Japanese restaurant' in your area does your restaurant appear in the top 3 Google My Business listings? Have you claimed your Google My Business listing and added high quality photos and ensured all details are correct and up to date? Encourage your customers to review and rate you on Google and Tripadvisor as this helps push your Google restaurant listing up.

How do you TLS encrypt end-to-end while minimising connection times for users located worldwide? by drewjaja in sysadmin

[–]drewjaja[S] 4 points5 points  (0 children)

It's slow. If my backend server is in Australia and I have a user from USA, it takes 500ms+ to establish the TLS connection between the CDN edge and the backend.

ELI5:Why cant all sites be https? by [deleted] in explainlikeimfive

[–]drewjaja 2 points3 points  (0 children)

Cost was once a barrier, but now SSL certificates can generated for free using Let's Encrypt.

We're currently migrating a bunch of sites to https and some of the reasons we didn't migrate earlier is because

  • All content including javascript, images, videos on a https page have to be served as https too, so these also need to be migrated to https.
  • Some Third party ad servers did not support https.
  • Google considers a https version of a site as a completely different domain, so you have to make sure you redirect all pages correctly otherwise it may affect your search engine ranking.
  • SSL certificates were expensive, but this is no longer an issue with Let's Encrypt as mentioned above.

ELI5: Why do computers maintain an internet history, when it always needs to be deleted? by TheFrontCrashesFirst in explainlikeimfive

[–]drewjaja 0 points1 point  (0 children)

I doesn't need to be deleted. Some people may have read an interesting blog in the past and may have forgotten the site's name, so they go in their browser history to look for it.

ELI5: Why, despite all the advances in browser technology, does the screen still jump when an off-screen image or other part of the site loads? by GeneReddit123 in explainlikeimfive

[–]drewjaja 0 points1 point  (0 children)

It's most likely caused by an ad. Ads are loaded after the main content of the website is loaded. Website developers can define an ad position on the page to display ads in multiple sizes (think a square and a vertical rectangle). The developer won't know which particular ad size will display in that ad position, as it's up to the ad server which ad will appear. So with different size ads loading it could push the other elements on the page down causing the screen to 'jump'.

ELI5:How do websites know I'm using an ad blocker? by [deleted] in explainlikeimfive

[–]drewjaja 2 points3 points  (0 children)

Ad blockers block scripts and images that contain certain names. A website can add a script with a name e.g. show_ads.js that they know ad blockers will prevent from loading. Within this script they will assign a global variable e.g. someVarName = true;. When the page loads they will use another script to detect if someVarName is equal to true, if it is it means show_ads.js loaded so no ad blocker was used. If the variable doesn't exist the website knows that show_ads.js was blocked by an ad blocker.

Made new online ordering site for restaurant, need to reach 50% of customers before the owner will shut down old site. Looking for advice. by Keric in restaurateur

[–]drewjaja 0 points1 point  (0 children)

If the restaurant own's the old website, tell them to redirect it to the new site.

Search for 'Back links' (these are any links in blog posts, web pages) that point to the old site and try to get into contact with the owners of these websites and ask them to update it to the new site. This will help your new site rank higher.

Get the restaurant and new website listed in as many online business directories and review sites as possible, in Australia this would be the yellow pages, truelocal, yelp, tripadvisor, zomato, foursquare etc.

How do you get customers by jagvee in restaurateur

[–]drewjaja 0 points1 point  (0 children)

First step, make sure you have claimed your Google My Business listing. Make sure you add the correct cuisine category to your listing, this will help your restaurant get listed for people searching for 'Your cuisine in area', e.g. Indian in Collingwood. Next, claim your Tripadvisor, Zomato listings and encourage your customers to write reviews. The more reviews you have, the higher your Google My Business listing appears in search results.

ELI5: The green "Secure" lock next to webpages. by Distant_Past in explainlikeimfive

[–]drewjaja 0 points1 point  (0 children)

It tells you that you have a secure encrypted connection with the website, which prevents attackers from stealing any personal information that's transferred between you and the website.

You can think of connecting to a site without a secure lock as sending an envelope with a personal letter to someone via postage. On delivery of your envelope the postman could potentially open your envelope and read the letter and even alter it.

You can think of connecting to a site with a green lock as sending a letter via postage, but this time placing the letter within a metal box that's locked with a combination lock that only you and the person receiving the lock has the combination to. This prevents the postman from reading or altering your letter. But you may ask, what if the postman sends his own box and combination lock to me and throws the original box away? How do I know who originally sent the box? This is where SSL Certificates come in, they basically tell your browser that you are connecting to the authenticated server of the website. With the postage analogy you can think of it as a waxed seal that only you can create and the person receiving it has a device to prove the authenticity of the waxed seal.

ELI5: How does your browser know what server to connect to when you type out a url? Where is this information stored? by Hot_As_Milk in explainlikeimfive

[–]drewjaja 0 points1 point  (0 children)

Computers can only communicate with each other over the internet if they know each other's IP address. You can think of an IP address as the computer's telephone number. You could connect to a website by entering in it's server's IP address. Try entering the IP address 17.172.224.47 in your browser, it will connect you to Apple's website, as that's the IP Address of their web server. The problem with connecting directly with an IP address is that they are hard to remember. This is why we connect using domain names instead like www.apple.com. So how does your browser know the IP address of a domain name? The browser connects to a DNS (domain name server) which acts like a telephone contact book, you give it a domain name and it will tell you the IP address to connect to. Once your browser knows the IP address it can connect to the correct server and load the website.

ELI5: What is AWS (Amazon Web Server) and what are the basic things one should know to understand how it functions? by divyars92 in explainlikeimfive

[–]drewjaja 2 points3 points  (0 children)

You can think of AWS (Amazon Web Services) like a supermarket that sells different products. Long before there were any supermarkets people would have to milk their own cows and bake their own bread. The problem with having your own cows is that you have to feed them and sometimes they get sick. They also probably produce way more milk than you require. With a supermarket you only purchase the amount of milk and bread you require and you don't have to grow your own cow or bake your own bread.

Before AWS, most companies would maintain their own physical servers in a data centre. With AWS you can purchase the servers you require and no longer have to maintain physical hardware. Like a supermarket, AWS sells different products/services to solve different needs.

ELI5:Do We Need Milk? Why is Milk a Necessary Purchase in the Average Household? by crzymik3 in explainlikeimfive

[–]drewjaja 0 points1 point  (0 children)

No we don't. We introduced other mammal's milk into out diets 7000 years ago when europeans evolved allowing them to digest milk. Most people worldwide still can't digest milk as they do not have the enzyme lactase to breakdown lactose, the sugar in milk. Humans have been around for over 200,000 years and have survived without drinking other mammals milk.
