Thanks Josiah
I installed mermaid (and the other bits from https://gt6796c.github.io/. 

The flowchart seems to work OK, seqdiag seems to be broken, of the mermaid 
stuff, dags and sequences seem to work, but gantt is broken.  For what I 
want to do, dags and sequences solve the problem.
Perhaps in future, some people shall tackle UML, BPMN, Southbeach, CORAS 
and perhaps even some generic drawing of computer networks.

Thanks to all who responded!

If you want to encrypt tiddlers in batch you have to do it through the control 
panel, encrypt tiddlers tab. Then out there the filter with the desired tag.

[tw] Re: Investigation: SVG in TW

[@TiddlyTweeter]

Thanks PMario

It makes sense. Thank you. I do think SVG & TW are a very good fit & it was 
the right choice to go that way for interface elements.

For my own stuff, rather than make loads of individual SVG Tiddlers I was 
thinking of using the  method to hold many related SVGs in one 
Tiddler. This enables using the ViewBox to display them in an easier way 
than other approaches. And you avoid loading a TW up with zillions of 
individual image tiddlers which become hard to manage. 

*However, there is an issue, perhaps. *

The easiest way to access "symbols" within an SVG (i.e. a discrete image 
with a "wrapper SVG") is to use ID's. *But I suspect this may conflict with 
TW basic working?* There is another method using the co-ordinate system of 
viewport and viewBox but it starts getting very complicated.

Before I start trying to work out details of how to do this I'd appreciate 
any comments you may have.

The "reference system" looks like this: 

A  definition example within an SVG (its largely independent of its 
parent) ...


  



The HTML call to it is, in theory, easy ...

['Mark S.' via TiddlyWiki]

I wondered that too. It appears to be for internal use. You could generate 
a whole block of encrypted stuff, but without a corresponding decrypt 
widget it's not very useful.

You might look at Danielo's code:

I really don't think any of this is remotely your fault. You could not have

Most of these problems stem from how much IBM has changed things.

That's what I meant by "take NoteSelf to the next step" in another thread. 
I'm not in a position to maintain the cost of servers (well, not in the 
long run) and such but I am hoping to build around NoteSelf to include a

password recovery, account deletion. I haven't had time to finish it either

I can't speak for the others, but you don't owe me an apology. The issues

Cloudant was a dot-com built to provide CouchDB as a server (PaaS/IaaS). It 
was so successful that IBM bought it. We are seeing the result of that.

The Apache CouchDB is what Cloudant is providing, You don't need both. If 
you are intending to host your own, then you wanted Apache CouchDB (I will 
assume this is what you wanted).

You want single node.

You want to set your admin name and admin password, this is your credetials 
as a CouchDB administrator/owner. Normally this would be a separate account 
from the one you use for your NoteSelf but it could be the same.

for IP, it depends on what you want...

IF you will only ever be using this from the computer that you install 
Apache CouchDB on, then put in "127.0.0.1", otherwise put in "0.0.0.0".

There should be a default port (5984), if you have to enter one, that is an 
okay choice unless you have a reason to change it.

Without CORS set, any website can use your Cloudant instance. However, the 
user using it would still need to have access to the database (note the 
default settings on a database is everyone has full access, including 
unauthenticated users).

That was one of biggest changes between TWclassic and TW5. 
SVG was specified and implemented into browsers, for a very long time 
already, before developers started using them. So the technology can be 
expected to be stable. ... and SVG has some advantages over font-based icon 
sets. ...

 - 1 pt is 1/72 inch mainly used for printing
 - 1 px basically is 1/96 of an inch, if you have a 96dpi display. .. Which 
was true for a long time. .. but now we have hiDPI screens, which only 
means, that 96px is aproximately 1 inch 

see.

I'm not 100% percent sure, why it is 128 units, but I guess it comes from 
bitmap-icon settings in most OSes. They start with 16x16 px for favicons 
and go up to imo 512x512 of even higher. So you see its a multiple of 16. 

So it makes sense to produce vector graphics based on multiples of 16 too, 
since there will be less scaling issues, introduced by math, if you export 
bitmap-images ... just some guesses here.

If you use the TW default settings, you'll get relatively good results, 
since they are battle-tested and the base themes work well with them. ...

have fun!

[tw] Investigation: SVG in TW

[Danielo Rodríguez]

It's definetively confusing. Every time I have to deal with an SVG icon in 
tiddlywiki I have the same doubts. At least I know that the pt unit is a 
relative unit, Wich is better than an absolute one like pixels
