Database fiddle sites

Posted by jpluimers on 2022/10/27

I knew there was JSFiddle for live playing around with JavaScript and more in your browser, so I wondered if there was a similar site for databases and SQL queries.

There are, so here are a few database fiddle sites: SQL playgrounds where you can live play with SQL queries (sometimes even without an underlying example database).

All via [Wayback/Archive.is] database fiddle – Google Search:

Getting meta data from an image URL – JSFiddle – Code Playground (not sure why it fails on the Chrome console)

Posted by jpluimers on 2022/06/28

It works as a [Wayback/Archive.is] Edit fiddle – JSFiddle – Code Playground.

And it fails on the Google Chrome console:

GET https://anniversary.archive.org/files/2021/07/October-2001-Google-Drive-7-19-2021-3-24-49-PM-768x276.png net::ERR_FAILED

The code is from [Wayback/Archive.is] javascript – Get width height of remote image from url – Stack Overflow (which has many more sync and async code examples that all fail in the same way, not sure why).

Glad the JSFiddle one works.

html frames and iframes from other sites that won’t load: some links

Posted by jpluimers on 2020/05/14

Back in the days, framing stuff from other sites would just work. Nowadays, often they don’t because of a variety of reasons, often the site not wanting to be embedded, which is OK with me.

But it pays knowing what they do and how they do it, to ensure it is not an accidental setting of the address bar URL to the wrong value like in

  if(top != window) {
    top.location = window.location
  }

So here are some links for me to dig deeper when I encounter framing issues again:

My basic idea for a workaround is to go through a proxy.

It looks like others had this idea too, so some links future reading via cors proxy – Google Search:

Some ideas to show a Google Calendar on a TV using a Raspberry Pi and HDMI output

Posted by jpluimers on 2019/01/10

Using OpenSuSE Tumbleweed E20 on Raspberry Pi 3: accessing the enlightenment desktop over VNC after automatic logon I wanted to buy an on-line read-only diary to help my mentally retarded brother see what his next few days are going to be like.

He increasingly has difficulty handling a paper agenda and has an agenda with 30 minute blocks like [Archive.isbol.com | Bureau Agenda 2017 – 1 dag per Pagina | 0041560163422 | Boeken (and the [Archive.is] picture on the right), but actually he needs 15 minute blocks during some portions of the day.

We call that kind “bureau agenda” which I think translates well into “desk diary”.

They were quite different from the agendas I used to have at school (:

For most school mates, they were more like this:

Had je een O’Neill of ging je voor De Familie Doorzon? De oude agenda’s uit je middelbare schooltijd zijn de verpersoonlijking van je eigen puber-ik. Afgelopen weekend startte in het Nationaal Onderwijsmuseum in Dordrecht de toffe tentoonstelling Grow Up over die vuistdikke, volgeplakte agenda’s.

Anyway, some ideas I initially had are below.

This is what I actually did:
