Web Development

PostgreSQL says it’s included in Ubuntu related operating systems, but I’m not sure. I’m unable to start the service, or set up new servers in PgAdmin. I’ve tried to install the repositories but I’m either getting “1831” architecture errors, or no release file errors. I’ve tried fixing the list file, but it doesn’t seem to help. If anyone can help i would really appreciate it

The course I’m taking provides download links for an installer for windows, and Mac. After this and another problem I’ve had on Mac back in the day I’m thinking of switching to windows. Maybe the development software works better there.

Hi, as title says, what framework do you use and why?

I have time to learn something new, but I can’t decide whether to use Svelte or React or any other thing there is.. My current job required PHP, Laravel and Codeigniter, which I kinda mastered but I feel that I need to move on.

So from your perspective and experience, which framework do you prefer? Can you maybe send me your favourite tutorial guy that does not have long boring videos just to have watch time ? (I don’t want to sit around and watch someone do it, I want to do it, videos are just for entertainment)

I want to learn something, but not decided yet what to use. Thanks for any advice.

I quite new to web development. I created a simple game which suppose to raise awareness to the RP syndrome (which I suffer from). The simple goal is to find Waldo but the twist is that there is nothing but him on the screen.

I want to add a "flashlight courser effect" meaning that the only visible part of the screen should be the one around the courser (for some fixed or maybe chosen radius). But, I don't want the rest of the screen (the non-visible) to be black but white / blank (as this is in a way the way that I see the world). The other elements (buttons, score and counter) should stay visible always.

Can someone advice me on how can it be done? Ideally there should be two switches (on the corner) one controlling the mode (full visibility vs limited field of vision) and the second one controlling the type of "darkness" (black vs white).

Here is the link to the repo with the current code: https://github.com/menisadi/RPWaldo

Thanks in advance

Update: Thanks everyone!!! I used the SVG idea and added the flashlight effect" (even added a switch to toggle the "flashlight mode" on and off). Working great. Thanks!

I have some complex touch interactions and am looking for a lightweight touch/gesture library to help me handle them. Interactjs is great, but it’s a fairly large bundle. Other top ones are not maintained anymore it seems.

I've been working on a neat little tool to create background textures/patterns in SVG. It has some presets, but also gives you full manual control of the settings. You can then copy the generated code output for use on your project.

Let me know what you think or if you find this useful!

Hi, I'm an old webdev who is rusty in CSS; I learn about calc() recently and never really learnt display: flex properly.

I made some webs with a responsive menu layout (relevant CSS code posted on bottom). I tried using flex but I still had to do one ugly hack: I have the menu heights for the different resolutions hardcoded and I have to update them manually every time a new chapter is added. It's not a big deal, but I would like to know if there is a proper way to do this.

Some alternatives I've thought about:

• The new round(), but it's too new and not supported by most browsers.
• JavaScript

... but I feel like there must be a clean CSS-only way to achieve this.

Thanks!

Relevant CSS code (link to full stylesheet in case I missed something).

ul {
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  height: 624px; /* =27x23+3 | 23 = 91/4 */
  margin: 0;
  padding: 16px 16px 4px 16px;
  vertical-align: top;
}
@media screen and (max-width: 1000px) {
  ul {
    height: 840px; /* =27x31+3 | 31 = 91/3 */
  }
}
@media screen and (max-width: 582px) {
  ul {
    height: 1245px; /* =27x46+3 | 46 = 91/2 */
  }
}
@media screen and (max-width: 400px) {
  ul {
    height: auto;
  }
}
  ul li {
    list-style-type: none;
    margin: 2px 16px 2px 4px;
    font-size: 120%;
  }
  ul li a {
    display: inline-block;
    background-color: #3fa79e;
    color: #d2e7e2;
    text-decoration: none;
    padding: 2px 8px;
    border: solid 1px #d2e7e2;
  }
    ul li a:first-child {
      width: 106px;
      margin-right: -3px;
    }
    ul li a:hover {
      background-color: #144c48;
      color: #fff;
      border: solid 1px #fff;
    }

I have been trying to import this sqlite database into mysql or postgresql database. But had been failing. Can anyone help me with this?

What TLDs to use if you cannot snatch a .com ?

Which ones are professional and generally well perceived?

I see this more and more lately: go to log in to some site, and they only show the username field. Enter username, click Submit, then a password field appears. Enter password, click Submit again, and then we're logged in.

This makes using a password manager super annoying, because I have to trigger the autofill twice.

Is there some security-related reason more sites are doing this? Is it an anti-bot thing? I'm just really curious, because it seems so pointless on its face, but it seems to be spreading.
