How to notify Web Browser clients of DB changes

We have a MYSQL database, with quite a few tables that are being constantly updated by many users.
We have rows of data that are presented to users through a web page.
Currently, the page data is refreshed every minute via AJAX. If someone makes a change on the web page, it is posted back to the server through AJAX. With the information being time critical, this is obviously not the best option, as we really need the information to update in near real-time.

What are the best options for performing this task?

Does anyone else get paid to host their clients’ websites with a host?

It’s just come to my attention that nobody else is doing this. So I am sharing the love… disclaimer: maybe eventually there could be something in it for me ;P

I host the sites I build for clients with a host that pays me to do so. (rev share)

It doesn’t make a fortune but it all adds up. Passive income after project handover.

Over the last 8 years I’ve built just over 100 small business websites in UK.

I’m not going to advertise on here for them but I can put anyone in touch & share the love!!

Most small businesses are happy to pay premium for hosting when you tell them its safer & is dedicated hosting though, not shared (SB owners are not techy at all)
I think most people who develop, don’t actually know how valuable the skills truly are because they are always surrounded by other tech heads
which is great for learning…steel sharpens steel and all that but majority of the world still can’t build a 5 page website & its 2021. thats where the easy bucks are. I make a passive £800p/m and climbing. When I get to 500 sites im semi retiring lmao

api – Auth system architecture for several different types of clients

We have the next client types:

  1. Classic web app (spa)
  2. Mobile app
  3. IOT devices

All these are API clients (they could be the third party also). Since we have a single data store, hidden by API facade, we’re wondering, should these API clients be separately authenticated or we need to authenticate them through a kind of ‘API auth gate‘?

So, the question is – how should we implement authentication/authorization? Is there any well-known pattern for our needs? As we imagine, this should be a single auth-server that will serve all the clients via an end-to-end token. Any thoughts, advice, suggestion. Sorry if the question is not clear, I can correct it with more details if you’ll ask. I’m just not so much familiar with such kinds of dilemmas 🙂

The joys of updating sites for "non tech" clients.

Tiny little rant.
I get a message that a local client of mine called to say he has some updates for the website we maintain for him.

Windows clients slow to open SAMBA on Debian 10 (when using short hostname)

I’m having a strange problem for windows 8 and 2012R2 clients, which use a Debian 10 samba server in ADS mode. The issue is slow initial directory listing of the server, only when using the server’s short name i.e. “server”

If clients use server.mydomain.example or Server_IP_Address connections are very fast. If they use server the connection takes between 1 and 30 seconds to show the initial directory listing.

I confirm that short name resolution works 100%. All windows hosts report IP address on:

nbtstat -a server


ping server

I tried to play some more with smb.conf (this works perfectly on my old Centos 6):

netbios name = server

With and without these options FQDN and IP connections are lightning fast, while the short “server” name takes some time. Usually clients return: 0x80070035 or 0x80004005

Have anyone had a similar issue?

freelancer – How can I reach clients who need CUSTOM web applications?

I want to offer web application solutions to businesses to help streamline their operations. I want to avoid the now flooded market of e-commerce sites, Wix websites, WordPress sites, etc. My skills aren’t necessary for a website that could be easily created using modern drag-n-drop website creators. The question is, how do I enter that market? The clients who seek more complex web applications are likely going to be big companies or smaller companies with a lot of money. They will be looking for developers with a lot of experience. I have no real-world experience but am confident in the skills I have learned. How can I even gain this real-world experience in the first place? I could certainly find local clients who need simple static websites, but that wouldn’t help me find the clients who need more complex solutions, right? Another factor to consider is that I am 16 years old and will be working by myself. How can I ensure clients take me seriously? I don’t mind offering cheap work at first, but clients will assume that my cheap prices must mean that my services aren’t good.

TL;DR: As a solo, 16-year-old web developer, how can I find clients who need more complex custom web solutions? How can I market myself as someone who offers software solutions for businesses that will actually help streamline business operations—not just static websites. How can I gain the credibility to be taken seriously as such a young developer?
