I presume AGG makes it easier to distort text for a visual Captcha 
...

Yep, we have our  own sort of flood detection running. I call it 
RID (rampaging intruder detection)


Problem with a captcha tyope solution is that we may need View to 
generate the random images. But our CGIs currently can only run under 
Core. Plus it disadvantages the visually disabled.

Each time I see an attack like this, it gives some more ideas for 
tightening up. Most of the time (like tis time) were one step ahead 
of the vandals.

That's awesome Sunanda.

Thanks -- we've been lucky so far.

REBOL isn't really a target  for hackers......Though it may become 
so if when it grows in popularity.

Here's an example of another Captcha - get the user to evaluate a 
rebol expression :)

They'd have to know REBOL first, though.

There are some very simple things we can do that would throw most 
of the stupid bots -- like a checkbox that has no other function 
other than to be checked.

Actually I was assuming that if they want to sign up for the library, 
they already have the rebol interpreter.

True.....but they might be in an Internet cafe that won't let them 
run REBOL.

methinks that is highly unlikely scenario

However, you can then point them to the freebell online rebol in 
java interpreter

The same bot  came back yesterday, via an anonymous proxy.

We are not alone -- this outfit is probing flaws in HTML forms on 
many (non-REBOL sites).

It would seem a reasonable security test on many websites to not 
allow sign-ups or feedback messages (etc) from anonymous proxies.

Hi Sunanda,


I have problems downloading the desktop librarian. Download always 
stops at 99% (tried with firefox and free download manager).

Thanks......Does the file as downloaded work or is it really incomplete?

Aaahhh, seems it's _more_ than complete ... and then somethings missing 
...

The length is as shown in the website, but the file downloaded starts 
with some html, so I guess that some other part is missing.

Neither rebol itself, nor me are able to find a rebol header in the 
file.

Thanks -- looks like there is a problem with the content-length header 
 (I thought there might be as I remember problems in testing when 
trying to get a value that all browsers were happy with. I think 
I've made IE happy while bemusing Firefox).


I've re-uploaded the script. It now doesn't set a content-length 
header. So, if you try again, it should work. But you may not get 
a download progress bar (because your browser isn't told the length 
in advance)

My apologies for the problem!

Thanks Sunanda,

it works now!

Thanks for retrying. Glad it's all hunkydory now.

I tried doing a search for "probe system" in the mailing list because 
I know it is a topic that has come up a number of times and has been 
discussed.  After spending 30 minutes searching for relevant conversations 
but came up with essentially nothing even though I tried alternate 
search engines such as Google.  I'd like the ability to specifically 
search for code snippets.  I tried different methods of entering 
the search value but in every case I ended up with {Searched for: 
["probe" "system"]}  That's not what I want.  I want "probe system" 
How do I get it?

what system do you want to probe?  (specifically what are you looking 
for?

Well, you could rewrite probe. The current probe will always stack-overflow 
because system/words/system = system.

Gregg wrote ObjBrowser which lets you "class browse" system

There's ROAM in the Viewtop "REBOL Tools" section.

(there is a comment inside obj-browser.r mentioning Ammon might use 
for RIDE IDE...and it might have some methods to do what you need 
to do.)

With google, put a search phrase in quotes:
     "probe system"
that will seek the precise phrase.

To restrict google to a specific site, the syntax is:
     "probe system" site:www.rebol.org


To search only some URLs within a site, give it a characteristic 
part of the URL:
     "probe system" site:www.rebol.org inurl:thread


Note that Google has not indexed all the thread -- which is why we 
added the in-site search.

I don't want to "probe system" after a while, if you wait long enough, 
then it will print out but I thought that there were some optimizations 
made to make "probe system" start printing sooner or something to 
that effect.  It's not "probe system" that I'm interested in.  What 
I'm interested in is finding the conversations that I participated 
in several years ago on the REBOL ML concerning the problems with 
"probe system"  but none of the search engines I used could produce 
them.

Sunanda, "probe system" site:www.rebol.org inurl:thread did not return 
what I was hoping for.  By dropping the inurl: then I was able to 
come up with one relevant thread and the rest of the results were 
talking about probing in the system object like system/script/args. 
 I can't seem to get rid of the /whatever after system with Google. 
 I was hoping that the ability use quotes to search for a specific 
phrase instead of breaking it apart and searching for multiple values 
could be added to the rebol.org search engine.

Really? I thought the probe system hang was fixed a long, long time 
ago, no stack overflow for me here. Besides it is better to just 
use 
save %system.txt system

http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-message.r?m=rmlFCPS
has Jeff and Bo probing about.

maybe use advanced search and specifically exclude the phrase "probe 
system/"   <--- note final slash

< I can't seem to get rid of the /whatever after system with Google.>

Yes -- Google doesn't understand that system/words (say) is a single 
item. While the REBOL.org seacth does. Ditto, the REBOL.org search 
recognises ! and ? as part of a word raher than discardable syntax 
-- so you can search for object? or datatype!

On the other hand, Google better handles phrases like "probe system" 
because its indexes include proximity information..
No one search is ideal.

what's the library response to Anton's request for webspace for the 
comlib project ?

So, Sunanda,  we don't have any proximity infomation and hence can't 
search for a particular phrase including space(s) like, "probe system"???

Graham, I don't understand your question.

I think Anton was asking for 10Mb to host the comlib project .. so 
something akin to that.

Correct Ammon. The REBOL.org search indexes threads (not individual 
messages) and does not include proximiy in its indexes.

So a search for [probe system] returns all threads that include either 
word.

Sunanda showed how I can use existing rebol.org technology (packages) 
to store and synchronize the comlib project files. But I am probably 
going to get a domain with Yeksoon.

Anton. as far as using Google and removing the phrase, "probe system/" 
that's as simple as adding -"probe system/" to your search phrase 
BUT Google doesn't acknowledge "/" as being anything other than whitespace. 
 Still, the fact that I couldn't even find it with Google was an 
implication that WE can beat Google.

Yeah, you're right, actually. I think I tried that before and was 
disappointed.

Unfortunately, the library apparently doesn't have an index that 
would be condusive to such a search.  Oh well.  Wishful thinking...

Did you try the topic index -- it's intended to categorise what a 
thread is about rather than what words it contains:
http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-topic-index.r?i=p

How about a fulltext-search on rebol.org, as option?

You can download Grahams' ML archive application (or. at least you 
could until he started having trouble with 1and1's hosting).

Assuming it's still available, you get 70Meg of ML messages and it 
has a search that runs on your ow desktop.

just tested Grahams' ml program and still not working :(

well, I finally made contact with 1and1 tech support.  They said 
it was a billing issue and I have to contact accounts on Monday. 
 Now, what billing issue could there be with a 3 year free account 
that has 1 year to run ?

Sunanda,  I didn't try that.  I had assumed that search would use 
that index as a key.  Is there a way to search the topic index other 
than by clicking on a letter in the alphebetical list and relying 
on the browser's find functionality?

Download everything and grep in the folder

I don't think I can download the entire ML archive from REBOL.org, 
can I?

Paid to less attention. Thought you want to search in scripts.
