IP to decimal function?

[Tim Selander via use-livecode]

Hi

I need to convert IP address from web logs to decimal for easier 
processing...


Before I try to "reinvent the wheel" (and no doubt roll off a 
cliff) I'm wondering if anyone already has such a function they'd 
be willing to share?


TIA

Re: SVG widget?

I wonder too. Seems with all the demand for SVG, it would be a natural to build 
into the engine. I’m trying to remember if getting SVG was a kickstarter goal???

Re: Transparent browser widgets?

[Jonathan Lynch via use-livecode]

I used to have an occasional bug in 8.1.3 where the browser widget would get a 
transparent background.

I had to restart the ide when that happened.

So, I think it may be possible.

Seeking recommendations / suggestions for use of library stacks.

[Alex Tweedly via use-livecode]

I'm starting to make more use of library stacks (partly because I'm 
trying to switch away from revIgniter to a CGI-based solution to allow 
me to do more work & debugging in the IDE).


And now I'm looking for best-practice and/or suggestions for how to use 
library stacks. The not-quite-obvious context is that if some other 
library is later put into use, and it has no librarystack handler, then 
the librarystack message can get through to my (already in use) library.


My naive approach (from non-LC background) was very simple :

all initialisation would be done in the librarystack handler

that handler would also set a script-local variable to avoid repeated 
initialisation


so something like

local sIHaveBeenInitialized
on librarystack
  if sIHaveBeenInitialized is empty then
put the millisecs into sIHaveBeenInitialized
  else
 -- setup initial / default values, etc.
 
  end if
end librarystack

This is fine for subsequent usage of the library - however, it's not so 
convenient while working on the library. The problem then is that any 
changes made to the initialization won't take effect unless I either 
manually unset this script-local, or exit / re-enter the IDE.


I thought about adding a reset handler, e.g.

on library_reset
   put empty int sIHaveBeenInitialized
   pass library_reset
end library_reset

which would give me a quick, safe and easy way to reset any (all) 
libraries from the message box. But then I thought it felt like I was 
rediscovering a wheel - so I thought I'd ask on here :-)


Is there another easier / better way to handle this ?

Thanks
Alex.

I'll bet that a transparent background for the browser widget is

What will be probably possible is setting the blendLevel of the

Yes. If you define path by "connected points" (I haven't seen
that in any specification).

But your example is a fine example for a nice option we have
with the LC-SVG icons:
We can simply "merge" some of them to one icon by merging their
(textual) iconPathes.

I cannot afford to be smug as my Linux rig (Xubuntu 16.04 64-bit) was hosed

What I do not understand is how organisations like the British State Health

(obviously) all sorts of safeguards.

My "underpants" may have a few holes in them, but everyone knows that
Windows is more holes than underpants, and it has been quite adequately
demonstrated that Windows executables running under WINE on Linux tend to be
faster and less vulnerable to viruses.

In about 1985, when I was an undergraduate, the news about AIDS was suddenly
announced, and the TV and radio was banging on about "preventative
measures": obviously the British medical authorities know their stuff re
medical matters, but when it comes to computer systems they neither know
anything much about them, nor do they employ people who do.

  Many years ago I read a science fiction book about people living in a
ploice state on Venus, which was, for the purposes of the story, a steamy,
soggy jungle planet with lots of muddy, hummocky islands in one big bog. The
rebels started communicating via AM radio (Amplitude Modulated) because the
authorities of the dictatorship had forgotten about that "old-Tech" and were
using FM (Frequency Modulated) equipment for all their communication needs.

Three days ago I got an e-mail from a chap in Ireland using a Commodore 64!

So, the answer, for us folks who don't have "endless boodle" to constantly
upgrade/update our machines, may lie in retreating into using ancient
machines . . . . so, I suppose my Summer will be spent on getting a
Winchester disc into my BBC Master Compact and sorting out how to get the
5-pin DIMM connection at the back to let me send and recieve e-mail
messages: after all, in 1989 I was using it, via Etisalat, to communicate
with various services even before the internet started.

You cannot send a virus to a BBC because the whole system resides on a ROM
chip!

Anyway, just at the moment I'm dusting off my G3 iMac running Mac OS

I'd guess that it wouldn't be hard to implement, but much harder to 
implement in a way performant enough for anyone to want to use. :)


I believe the browser widget maintains its own buffer, blitted to 
screen.  This makes it fast, but prevents it from mixing its rendering 
with LC-native controls.


For mixed rendering it would need to render within the compositing 
process Mark Waddingham outlined here a while back in answer to Jacque's 
question about acceleratedRendering.  My guess would be that doing so as 
rapidly as a browser might conceivably update would be computationally 
expensive.


That's just a guess, though.  I'd be happy to be wrong. Integrated 
rendering of the browser widget would be nice.

LC Server is a good solution for people who are very accustomed to

Like any app that uses stdin/stdout, it can be used as a CGI under 
Apache to provide server-side processing for dynamic web pages and other

While this specific exploit happened to be Windows-specific, this isn't 
really a Windows issue.


It's a "USE A SUPPORTED OS VERSION!" issue.

From the information available thus far, it looks like Microsoft did 
their job.  They provided protection against this vulnerability months 
ago, and have been warning people not to use older unsupported OS 
versions for years.


If someone switches from Windows to macOS or Linux, as long as they keep 
using OS versions beyond EOL they'll still be putting themselves (ansd 
potentially any system they connect to) at risk.

...hopefully without an Internet connection, since Apple stopped

Transparent browser widgets?

[Jonathan Lynch via use-livecode]

Apparently, both WebView (android) and uiwebview (iOS) have transparent modes.

Would it be easy for the LC team to implement a transparent mode for browser 
widgets, where the background color is transparent, allowing other objects to 
show through?

This would obviate the need for some the processor intensive image transfers in 
and out of the widget.

I know one would have to set the background-color of the body element to 
transparent and set a couple of settings in the WebView calls. Is that all it 
would take?

Have you tried that in 8.1.4 RC2?

If the problem is repeatable with the latest build you might want to file a bug

will be spent on getting a Winchester disc into
my BBC Master Compact and sorting out how to get the 5-pin DIMM 
connection at the back to let me send and recieve e-mail
messages: after all, in 1989 I was using it, via Etisalat, to 
communicate with various services even before the internet started.


You cannot send a virus to a BBC because the whole system resides on a 
ROM chip!


Anyway, just at the moment I'm dusting off my G3 iMac running Mac OS 
9.2.2 with Classilla.

While it's true that this particular exploit is dependent on a 
Windows-specific vulnerability, this is no time for smugness. There's 
a larger issue here relevant for all of us:


IF YOUR SYSTEM US NO LONGER RECEIVING UPDATES, IT'S NO LONGER 
RECEIVING CRITICAL SECURITY PATCHES FOR KNOWN VULNERABILITIES.


Any such system, if connected to any network that connects to the 
Internet, should be considered too dangerous to use.


Doesn't matter whether it's Windows, macOS, or Linux.  Once the OS has 
reached EOL, either upgrade to a supported OS version or turn off all 
network connectivity.



This exploit has become a global tragedy, but worse is that it appears 
to have been preventable:


Microsoft issued a patch protecting against this months ago, and for 
the (shockingly large number of) machines still running XP, Microsoft 
spent literally millions over a many years reminding everyone of XP's 
EOL date and encouraging them to upgrade to a supported OS version.


Apple (for reasons only they can discern but AFAIK have not disclosed) 
are less kind to their users, often stopping updates without explicit 
notice and little if any forewarning.  They do advertise when new 
versions are available, but generally haven't provided clear notice 
when EOL is reached for a given version. For example, when Snow 
Leopard reached EOL, even though some 19% of all Macs were still 
running it, no notification was provided that it would not be 
receiving patches; it simply stopped getting them.


With Ubuntu, EOL date is well advertised even before a version is 
released.  That project follows a fixed release cycle in which all 
long-term support versions get exactly five years of updates, and all 
interim releases get 18 months of updates.  You know even before you 
download exactly when it will reach EOL.


With all three, once you know it's reached EOL you must either 
upgrade, or put yourself and your organization at risk.


If the post-EOL exploits that occurred with Best Buy and Target a 
couple summers ago didn't drive the point home clearly enough, 
yesterday's global attack should:  "What, me worry?" is not a sound IT 
policy.

Re: sysError List?

Hi Richard,

Ok, so I did the upgrade to version 8.1.4 RC 2 and
after rebooting I found that it made no difference at all.

When you are using lc-server and use
the following script, what do you get?



Thanks,

That value is either accurate or inaccurate. Either way, it seems a bug 
- the question is, where?


If accurate, it would appear there's something very unusual about your 
OS config, since temp files are a common necessity in modern OSes.


If inaccurate, it would appear to be a bug in LC 8.1.4 RC1.

Have you tried that in 8.1.4 RC2?
http://downloads.livecode.com/livecode/

If the problem is repeatable with the latest build you might want to 
file a bug report on that.


FWIW, testing both LC 8.1.4 RC2 and 9.0 DP6 I get a valid path to my 
system's temp folder.

Re: SVG powered images

[Jonathan Lynch via use-livecode]

I feel like HH has an important point - this method uses a lot of processor 
power. We should minimize the burden on the processor (small animation, 
efficient JavaScript) and make sure our target users will consistently have the 
processing power to handle this kind of animation.

Your letter "R" is not part of the (single) path.

@Richmond
The widget SVG Icon is set up to display at most ONE SINGLE path,
no matter where the path comes from.

The format must according to dict fulfill the SVG specifications
https://www.w3.org/TR/SVG/paths.html#PathData.

I tested the svg-to-png conversion using both revBrowser and browser widget on
Mac 10.12.4. This works. It doesn't work on Mac 10.10. (probably also Mac 
10.11).
This is caused by webkit which LC uses on Mac.
Where it runs, taking frames from an svg animation or from a video is 
"stuttering"
because the svg or video already takes most of the graphic card's power.

@Alejandro
This SVG animation is a fine demo to show that pure LC script can be much better
than SVG animation. Adjust there with a menu the speed to your machine (you can
also change color and sizes of the gears while the animation is running).

Re: SVG powered images

For svg animation, it seems like it would be more efficient to let the 
animation play in the widget and just periodically export a frame, rather than 
rewrite the svg every time.
