Doing only a count(*) is faster without the subquery... and is what we have 
switched to.

So does the limit reduce it to less than 1 day's rows?


Yes, the idea of the limit (900k records) was to limit it to the records 
within 1 day and then run the query on the smaller record set.  However, 
after your comments, when I was looking around, I resolved that the 
slowness is because of the count (distinct x) and not because of the 
indexes, etc.


For reference, on a 230million record table, the numbers were roughly 
along these lines:
* SELECT count(*), count (distinct group_id) with a limit of 900k 
records based on ID DESC, followed by the recorded_on part = 8.6 seconds
* SELECT count(*), count (distinct group_id) on the whole table using 
only recorded_on in the WHERE = 14 seconds
* SELECT count(*) only with a limit of 900k records based on ID DESC, 
followed by the recorded_on part = 700ms
* SELECT count(*) on the whole table using only recorded_on in the WHERE 
= 350ms
--> Clearly, the culprit was the count (distinct group_id) - that 
benefits a lot by using a subquery to limit the number of records it 
considers
* SELECT count(*) from (select distinct group_id from data_store_v2 
where recorded_on >= '') --> takes around 900ms


So, we are combining these in the final query now... this takes around 
900ms to get both values (count and count distinct)

-- get the fields from 2 different subqueries
select * from
-- first field is got for the count(*)
(select count(*) AS all_count from data_store_v2 where recorded_on >= 
(now() AT TIME ZONE 'Asia/Singapore' - '24 hr'::INTERVAL)) as t1,

-- and Joining in the second one for the count (distinct group_id)
(select count(*) from
-- this is yet another subquery
(select distinct drive_id from data_store_v2 where recorded_on >= 
(now() AT TIME ZONE 'Asia/Singapore' - '24 hr'::INTERVAL)) td ) as t2;



But as I mentioned, this is now a PostrgreSQL question not an 
ActiveRecord or Rails question :)


Thanks for digging with me!

Best Regards,
Mohit.

Your email got me going back to look at all the parts again since obviously the

problem is the count(distinct group_id) part which seems to be quite slow in 
PostgreSQL.  This is a lot faster:
select count(*) from
(select distinct group_id from
data_store_v2 where recorded_on >= '2015-06-06') td;
than:
select count(distinct group_id) from
data_store_v2 where recorded_on >= '2015-06-06';

as explained here: 
https://www.periscope.io/blog/use-subqueries-to-count-distinct-50x-faster.html

So, I guess the real problem was being masked by something else and an 
incorrect assumption on my part :)

I would expect the select count(distinct...) to be a major contributor to the 
time taken by the query, just given the amount of work it must do. The select 
count(*) from (select distinct...) alternative is a nice tip :)


...and that is what the cause was.


Thanks for the analysis :D
I do understand SQL and I thought I'm not throwing things together... for my 
understanding, which column was unnecessary?  I thought we needed all:

group_id for counting the distinct group_id
recorded_on for the subsequent query on it
id only for getting the most recent records

I apologize--I misread the query structure. I got it into my head as:

select ... from (select ... from ... where recorded_on ... order by ... limit 
...)

I think you can see how THAT query would have better fit my description of 
being poorly constructed.

I'm glad that my somewhat off-base pontification still managed to point you in 
a useful direction!



Yes, thanks again.

Some suggestions in a slightly different direction:

1) rewrite without that completely unnecessary subquery, and see if the query 
time improves ;-)


We have tried this and the query is quite a bit slower.  Filtering to 
the last 900k records before doing the recorded_on part helped speed it up.



2) check that appropriate indexes exist and are being used by the optimizer

3) really analyze the query execution plan, and look for more advanced 
opportunities, for instance, order by recorded_on instead of id, since, presumably, 
the query will already access the rows by an index on ordered_on; consider dropping 
the limit & order altogether; take that query to a PostgreSQL list...


Your email got me going back to look at all the parts again since

4) put some effort into learning SQL better; OK, we all make mistakes sometimes 
and maybe this is just that; but it sure looks to me like someone who doesn't 
really understand SQL struggling at throwing together various clauses until the 
correct answer pops out (note that in addition to the issue I pointed out in 1, 
the subquery is selecting a column which is completely unused--probably doesn't 
affect anything, but just another sign that the person writing the query did 
not understand it).

Most of my personal work is with SQLite3 on embedded platforms, but this

Rails issue to being a PostgreSQL issue.

That way, when we want something recent, we would just query the most

go to the larger tables that are sharded.

[Rails] Handling Hot Data with ActiveRecord

[Mohit Sindhwani]

Hello!

We are thinking of different ways to handle hot data in our system.  We 
get a lot of information that's very relevant for periods of time.  So, 
for example, we have some data that we query on the basis of

> counts over last 30 minutes
> data collected in the last 30 minutes
> items collected today
> items collected within the past week
...and so on.

We are looking at different strategies to keep this data updated and to 
manage scaling the database.  So, we are looking at horizontal sharding 
[splitting data into multiple tables that inherit from a master and have 
exclusion constraints] and are also considering having tables that hold 
data as:

> All the data
> Data for the last 24 hours
> Data for the last 2 hours
That way, when we want something recent, we would just query the most 
recent table, but in the few occasions that we need something more, we 
go to the larger tables that are sharded.


Just for reference, we are doing something like this:
select count(*), count(distinct group_id) from
(select group_id, recorded_on from data_store_v2 order by id DESC limit 
90) td

where recorded_on >= (now()  - '24 hr'::INTERVAL);

We are getting 800,000 data items a day right now and the above query 
takes around 14 seconds on a single table that is not sharded and has 
around 268million records.  Every week, this table becomes slightly 
slower since we add close to 6 million records every week.


I've read this: 
https://www.amberbit.com/blog/2014/2/4/postgresql-awesomeness-for-rails-developers/ 
and am looking at ways that everything is managed under Rails, if possible.


So, the questions (and thanks for reading this far) are:
> What is a good way to do this while still working within ActiveRecord?
> This is a capability that we'd like to attach to any model that might 
need it.  What would be a good way to approach a gem for it?


I'm sure there will be a few more questions as we progress on this.

Thanks,
Mohit.

Colin



I'm actually writing a C++ client that accesses information using HTTP

"http://redmine/projects.xml"; and "http://redmine/users.xml"; to get full 
lists of projects and users. The relationship between these 2 resources 
is a HABTM.  I'm trying to figure out if there is a default URL (i.e., 
Rails convention) at which I could GET the relationships so that I can 
figure out which users belong to which projects... or figure out which 
users belong to a specific project.  Since I'm doing this from C++ and 
not from a Ruby client, I am trying to figure out the URL, method and 
parameters that I need to provide to get this information.


Hope it's clearer now?

Given how much trouble I'm having explaining this, maybe, I should stop 
searching and start reading the source for Redmine..

Mohit.

[Rails] Rails ActiveResource URLs for searches including habtm relationships

[Mohit Sindhwani]

Hi!  I'm trying to build a small client that connects to Redmine to get 
the list of users attached to a project.


Following the AR/ Rails conventions, I can get back all projects as:
> http://redmine/projects.xml

and do searches such as:
http://redmine/issues.xml?limit=10&project_id=3

This works when it involves an attribute or belongs_to criteria.

Can someone help me understand the URL that should be used when trying 
to search on a HABTM criteria?


For example, I want to know all the users on a project.  But that 
relationship is achieved through a HABTM table.  Is there some default 
Rails routing that covers this scenario?


I tried searching online but I'm just not being able to formulate a 
query that returns useful results.

[Rails] Mongrels don't restart on Reboot

[Mohit Sindhwani]

Hi All,

I'm trying what seems like a textbook deployment of Rails on an Ubuntu 
Server.

* I have a mongrel_cluster with 5 Mongrels behind an Apache server

I have been trying to follow the guides on how to get this to start up 
on reboot and just can't seem to get it done!  The guides make it seem 
easy, but I can't get it to work - so, I'm doing something wrong and 
can't find what it is.


Here's the setup:
* I'm using the Bitnami Ruby/ Rails Stack on AWS
* The root user on login is bitnami and is without password
* The login is using a pair of keys and putty
* I created a new deployment user called xmongrel with a group xmongrel
* I used mongrel_rails cluster::configure with the full path to the app 
and N=5

* Ruby is in /opt/bitnami/ruby
* The app is a Radiant site in /opt/bitnami/projects/rails_s04
* As the user bitnami, doing this does not start the mongrel_rails:
> mongrel_rails cluster::start
* After I do 'su xmongrel' and log in with the password, it works:
> mongrel_rails cluster::start
* I have mongrel_cluster copied to /etc/init.d
* I have also done:
> sudo /usr/sbin/update-rc.d -f mongrel_cluster defaults
(It gave me a warning about missing LSB info - though the script 
looked ok!)


I have been at this for quite a few hours now, and I'm still not getting 
anywhere.


What can I do to debug/ fix the problem?  Any help will be appreciated.

Best Regards,
Mohit.

[Rails] Mongrel failures but nothing in logs

[Mohit Sindhwani]

 Hi All,

We are having a few strange problems in production.

The Rails 2.3/ Ruby 1.8.6 application is hosted using Apache/ mod_proxy/ 
mongrel_cluster (managed by monit) running on CentOS.  This connects to 
a PostgreSQL instance running on a Windows  2003 server (it's behind a 
load balancer but the PostgreSQL port is redirected to one machine.


Suddenly, without reason or upgrade, the Rails app is returning 500 and 
nothing is in the Rails log - not in the mongrel logs, not in the 
production log.  We seem to be able to safely connect to a static image 
file - so, it should not be the Apache, we think.


We checked a few things:
* mongrel has the rights to folders like tmp and log
* the disk can be written to

Since nothing is in the logs, we are baffled - what could we check?

Thanks,
Mohit.

[Rails] Performing Faster...

[Mohit Sindhwani]

 Hi All,

We are building a maps based site in which we serve out map tiles 
created by us.  The entire application is working well enough and we 
have followed through on most of the best Rails practices to speed up 
things.  We have also now gone through the list of YSlow and typical 
HTTP practices to further reduce the time spent in the application.


I guess it's now time to go beyond the design and look at what can be 
done with the servers.  We are using a traditional Apache + Mongrel 
Cluster for deployment at this time.


I have been reading and Thin looks attractive, as do Nginx and 
Lighttpd.  I am wondering what we should look at next.


Serving map data requires us to server a number of tiles (256 x 256 
pixels each) to create the map the user sees.  Naturally, we will add 
"expires" headers, etc. so that the client caches it (if it can).  We 
are just wondering if there is a recommended way to reduce the time it 
takes to serve files.


The tiles are served from a complex directory structure on four assets 
domains.  Is there a "very fast static file server" that you would 
recommend us to use?  Any experience or guidance would be great..

Re: [Rails] Double render/redirect philosophy

[Mohit Sindhwani]

On 9/2/2010 3:04 AM, Ralph Shnelvar wrote:

Ok, I think I understand why RoR will flag an attempt double render in
an action.

What I don't understand is the philosophy of render and redirect_to.

Specifically, why isn't a return implicit in both those methods?

Or, I guess, more to the point ... what are the advantages of writing
code in the action after a render/redirect_to?
   


I'm not sure how Rails works, but in a C++ HTTP server that we did, we 
could do something like write the response to the browser and then do 
the remaining house-keeping tasks.  For example, it would be perfectly 
fine to update the logs, perform some other calculation, etc. that does 
not affect the output (since it's been sent off already) but is 
something that the system could use.


In another system, we did something like receive a request by HTTP POST, 
check the parameters and acknowledge the receipt of the request to the 
client as the response.  Thereafter, we needed to process the request 
(which took quite a while) and then we would POST the results to a URL 
on the client's side.


I think both these cases would be things that don't need to be put into 
an after_filter and would benefit from writing code in the action after 
a render (assuming Rails works/ allows one to work this way).

Thanks Jacob.  I think you've given me a couple of pointers on how to

This seems simple enough!  Would this approach also work if someone was 
already accessing the older file when we try to do the second set of steps:

$ touch some-file-v2
$ ln -sf some-file-v2 current-version


Can I update a symlink while someone is already reading a file?

Actually, I do use this for one of our solutions.  The only concern is 
that you need many more Mongrels if your files are very large - since 
sending the file from database locks up the Mongrel for a longer period 
of time... with small files, it works quite well.

Mohit.

[Rails] Something like a file server

[Mohit Sindhwani]

Hi, I'm sorry if this is slightly OT, but I'm trying to find a way to do 
the following.  I have a bunch of processes that generate regular update 
files.  Each file may be between 100KB - 4MB in size.

On the other side, I have people who want to pick up the most recent 
version of this file.  So, I need to give them a fixed URL to the file.  
When they make a request, they would like to get only the most recent 
file.  Initially, I thought that something like FTP would work, but I 
run into the problem that if a request comes in when the file is being 
updated, the client may not get a valid file.

The other extreme is to have an upload controller and a download 
controller and then store the file in a database, so that it can be 
served up through the database.  The database serializes it so that I 
don't have to worry.  But, since the files can be large, it seems a bit 
of a waste to use this approach.

Is there a better way?  Anything that you would recommend?

Thanks,
Mohit.

Hardly :)  I just use that a lot!!  A lot of  my work involves data 
conversion and when outputting it, sending out 7 or 10 decimal places 
looks clumsy.  So, it's short hand that I've become accustomed to writing :)

I'm not going to be able to help this yet, but just to add to it.  What 
level of granularity do you want to provide?  Can people search by the 
places within a city?  How about different shops/ outlets within a 
city?  Does it matter which branch generated the document?

My apologies in that case.  Sorry to all.  Just that with the volume of

You need to install the development set for SQLite3 since the gem has a 
native build.  From:
http://theplana.wordpress.com/2007/05/11/install-sqlite3-on-ubuntu/

you need to do the equivalent of the below step:

* Install Sqlite3
sudo apt-get install sqlite3 libsqlite3-dev
sudo gem install sqlite3-ruby

I'm sorry I'm a limited Linux user (and mostly use Ubuntu there).

Not sure what you mean by the last part, but Radiant has snippets that 
can be rendered in lots of different places.  If you could clarify a bit 
more about what you mean, I could help you see if Radiant is similar to 
what you need.

Definitely Rails would be simpler than a lot of other choices.  Java 
would sound more 'enterprisey' than Rails.  I'd like to hear an answer 
to this question also actually.  We're currently doing this kind of 
thing as 'App servers' written in C++ (currently for Windows with either 
SQLite or PostgreSQL).  The thing just sits there and collects data and 
when someone wants it, it hands out the results, or does some 
processing, etc.  It's designed as an HTTP server, so it integrates 
rather seamlessly with the rest of the infrastructure, but is more 
time-consuming to do... than it would be in Rails.  However, it does 
give reasonably low memory footprints and because of the way that it is 
designed, it scales well with extra CPU power or cores (mostly it's 
stateless, so very few occasions to lock and wait, etc.).

Fortunately, we are not doing much stuff on the output side (where ERB 
templates would be great!), so I'm not complaining much.  Most of the 
output in our cases is either text or XML, but we have one server we 
built that does dynamic images).

I know my rambling isn't helping here, but you're not alone in that 
conundrum.

Cheers,
Mohit.

I find HostingRails good enough for most things.  I have a couple of 
Radiant sites and a Mephisto blog deployed to the same host.  All work 
acceptably.  Their cheapest plan will set you back by about US$4.00 per 
month.  If you're just playing around, I think their shared hosting is 
quite decent.  You can see http://onghu.com/te and 
http://notepad.onghu.com/ for response time, etc.

I can vouch for their tech support - it is quite quick and responsive.

Is it just the loader that is slow?  Or is there something that can be 
done in the way of passing extra information (such as fully qualified 
paths or something) that would help.  I don't want to start a discussion 
about the "better OS" or "quit Windows", etc. but given the install base 
of Windows, it would be good to know if there are things that one could 
investigate to speed up Ruby on Windows.

Not directly related, but if you just need to remove the leading/

You could create a message queue in a shared database of some sort.  All 
applications insert their "to send" emails into the message queue 
(database table) and a regular job starts up and reads in the details 
and tries to send them.  If it manages to send it, it cleans up for this 
record (i.e, deletes the item from the table and/ or informs someone).  
If it doesn't manage to send the email, it increments some sort of 
"retry count" in the database and waits again.  If a message fails to go 
after a certain number of tries, it simply marks the message as 
undeliverable and removes it from the message queue to a "failed items" 
database.

Now, I wonder if there is a message queue implementation in Ruby that 
does this?

[Rails] SMF Forum + Rails - any experience?

[Mohit Sindhwani]

Hi, I'm trying to see if I can get Simple Machines Forum (SMF) coexist 
with a Radiant CMS site.  So far, I have only found this: 
http://railsforum.com/viewtopic.php?pid=49374 which gives some idea.  
Also, SMF exports out some data such as 'Recent Posts' that I should be 
able to parse and create some pages on that basis.

Now, my Radiant site needs login - not to manage the content, but to 
possibly post comments.  I was wondering if anyone has any experience in 
sharing user logins, etc. between SMF and Rails?

Any general experience with both?

Thanks,
Mohit.

Should not need anything special.  How do you know it doesn't work?
Also, are you using forward slashes in the path?  That may not work.
Are there spaces in the path to file.bat?  That may not work.

I think you could get something like Acronis True Image and that can do 
a lot of stuff including backup your entire OS image and your data.  If 
something goes off, you can probably restore the image within a couple 
of hours almost back to where you left it.

Easiest is probably to base it on Ubuntu or CentOS.
Most efficient is likely to be Gentoo - given the older hardware that it is.

I think others have already given hints on what can be done.  I wonder

Sorry for the trouble you're experiencing.  Try the Radiant mailing list 
- you're likely to get good help there also.  That said, as a general 
guideline, you should never really need to run in development (that part 
is for developing the CMS itself, not the content).  You should run in 
production.

Also, when you do that, make sure you follow the instructions over at 
the site.

The documentation is a bit all over the place right now, but is being 
reorganized.  Take a look at: http://wiki.radiantcms.org/Summer_Reboot 
for bits of documentation that will help.

Also, specifically see: 
http://wiki.radiantcms.org/Create_your_first_Radiant_project (with 
video, I believe) and then see: http://wiki.radiantcms.org/Getting_Started

Make sure that you're on Ruby 1.8.6 - there are still a few kinks with 
Ruby 1.8.7.

Cheers,
Mohit.

If I'm not wrong, relational algebra doesn't identify a sequence between 
the elements of a row, i.e., I don't think it gives you the ability to 
select a column specifically.  That said, you could probe for the schema 
and get the elements using that - something like how the dynamic 
scaffold used to work in earlier Rails.

sure.  It's a bit odd for you to assume that no one else in the world 
wants to move to New Dehli (sic).

[Rails] RForum on Rails 2.x

[Mohit Sindhwani]

Hi!  Has anyone tried to/ is running RForum on Rails 2.x? 

At least as deployed to Ruby Forum, it seems super fast with multiple 
forums, has good follow-up features (e-mail), a decent messaging system 
between users, very decent anti-spam features and a whole host of nice 
things - it does seem to be one of the most feature-complete Rails-based 
forums.

Now, looking around shows that it was last updated date at the end of 
2005 - that's the only downside.  If I'm to use it for a site that we'd 
like to keep alive for a year or more, it would be good to know if it's 
working with Rails 2.x - I guess the main worry is that hosts will 
eventually upgrade to Ruby 1.8.7 (or newer) and that will break the 
older Rails and that would break the RForum.

So, coming back to the question - has anyone tried to/ is running RForum 
on Rails 2.x?

Thanks!  All inputs deeply appreciated.

Cheers,
Mohit.

I'm not sure what you are trying to do, but a primer in Ruby loops will 
help, from the look of it:

then, you just need to install SQLite3 - search up to find a guide for 
your OS.  It's quite simple.  You will also need to install the 
appropriate Ruby gem for it.

For one of my sites, I want to create a developer API so that other 
people can leverage of what we build to quickly put together their own

I can't explain why it doesn't recognize but you could add something to 
the end of the address and split.

irb(main):014:0> a = '[EMAIL PROTECTED]@@'
=> "[EMAIL PROTECTED]@@"
irb(main):015:0> a.split('@')

Hope this helps.

Hi Fernando, thanks for the reply.  So, it does seem that the general

In Rails, all options are still open to me... my curiosity is currently 
piqued by Vanilla which is something that looks very interesting.

[Rails] The Forum Hunt continues...

[Mohit Sindhwani]

I'm still looking around for a good forum to integrate with a Radiant 
site that I'm working on, and I have narrowed it down to three options 
in the Rails world:
(a) RForum - that seems to be updated less frequently, but seems quite good!
(b) Altered Beast - quoted as an exemplary Rails 2 application
(c) El Dorado - Seems quite nice and has nice extra features

As such, my main requirements are quite simple:
(a) Multiple forums, discussions and messages
(b) Good spam controls and support for moderating messages, users, etc.
(c) User control and registration
(d) Some integration with e-mail (like watching threads) - optional.
(e) Support for multi-lingual messages (UI doesn't need to be)
(f) Some support for Integration: modify style sheets, simple recent 
messages page, a simple user model, etc.

Looking around in the non-Rails world, I find that PhpBB is popular but 
has a bad name when it comes to security and some people say that it is 
quite hard to integrate with/ change.  Another one I stumbled across is 
called Vanilla and it seems to have a good reputation for a clean UI and 
ease of integration and support for add-ons.  URL: http://getvanilla.com/

Does anyone have any suggestions/ experience to share?  It is acceptable 
for the BBS to run on a separate sub-domain from the Radiant site.  
There is no need for there to be very tight integration between the two.

Thanks for your help.

Cheers,
Mohit.

On Windows, I think you need 1.2.3 - so you should do:
gem install sqlite3-ruby --version 1.2.3

That should get it working.

[Rails] Re: [ANN] El Dorado - an open-source forum in Rails

[Mohit Sindhwani]

Hi Trevor

Thanks for the long message.  I do appreciate the reply.  I've been 
following the project (in terms of watching the mailing list posts to 
the Rails mailing list) and haven't seen much about it.  That either 
means it works really well or people aren't using it or people are going 
elsewhere for support!  I noticed yesterday that the El Dorado Forum 
itself is quite active... so, I'm now going to start tracking it.

It looks nice, seems to have many features that I want - now, I need to 
suck it down, install it and play with it.  Was just looking for a 
"heads up - beware!" message before starting out.  Given that there have 
been none yet, it's probably a good idea to go ahead with it :)

As you're probably well aware, Beast (and its variants) are most 
commonly cited as options for integrating into regular apps... so, I was 
just doing a check before I start to evaluate.

The remaining answers are inline.

Good enough for me!  It gives me enough confidence to go ahead and start 
evaluating it for our needs.  I do like some of the stuff that's catered 
for small companies - and I think that will see us use El Dorado for 
more than just 1 thing in the near future.

I would be careful of claiming "integrate" just yet. 

[1] The most likely scenario currently is that Radiant runs on 
http://www.example.org/ and El Dorado runs on http://bbs.example.org/

[2] The second most important thing is likely to be a need to make sure 
that somehow Radiant and El Dorado can share the same user 
authentication method (for Radiant, this would NOT be the admin login to 
post content)

[3] This would most likely be followed by an integration where I add a 
sidebar in Radiant (so, I'd need to add Radius tags) that will allow us 
to copy across the 10 most recent posts (subject, title, author, etc.) 
to the Radiant site's home page (or any other page for that matter).  
I've done this before using Yabb2 - that site is currently offline, 
otherwise I'd post you a link.  So, what I'd need from El Dorado is a 
not too complex page of 'most recent posts' and then parse that in on 
the Radiant side.

[4] I'd like to then see if it's possible to add simple things like tags 
that allow you to search for BBS posts related to the current page in 
the forum.  So, I'm thinking that you could do  and this would find you some posts related to 
'form_helper' and if it that comes back in a good easy to parse format, 
I'd like to show that on the Radiant page.

[5] Finally (and this is a big problem), I'd like to see if it's 
possible to use the 'home page' of the user inside El Dorado for adding 
more things - e.g., if he could bookmark something in the Radiant site, 
it could show up inside this user home page area.

What do you think?

I'm aware of this, but I have spent quite a bit of time with Radiant and 
the site that I have this in mind for is already starting out on 
Radiant.  Additionally, I'm helping to coordinate a project called 
'Summer Reboot' that is helping to create documentation for Radiant, so 
for now, that's the chosen one: http://wiki.radiantcms.org/Summer_Reboot

Of course, I will.  I think the main features that I'm looking for are:
1. Ease-of-use
2. Ease-of-integration (e.g. the simple pages that allow me to integrate 
with Radiant)
3. Spam control/ management - this is really troublesome naturally!  I 
have this working quite well on the Mailing Lists

I know I'm replying to a really old email, but I was wondering how 
things are going with El Dorado?  Are many people using it?  Any obvious 
problems?

I'm looking to integrate something alongside a Radiant website, with the 
main need being that the 2 should be able to share some sort of user 
model (not the Radiant Admin UI model).  So, I was wondering if people 
have used it and have some comments to share.

Thanks
Mohit.

I'm sorry I can't help you directly but is the above spelling error for 
disposition actually there in your code?

Does it work in Firefox?  Does it show that the MIME type is unknown?
Sorry, I'm out of ideas for now in that case.  Hopefully someone else 
can help.

I had a similar problem that a dynamically generated PNG was 
re-requested when a user right clicks and does a 'save' (both in FF and 
IE).  There was a GET request triggered after the initial POST that 
generated the image.

We got around this by setting the mime type to application/unknown for 
the content.  That way, IE and FF do not try to decode the content and 
do not try to 'support' it through plugins, external programs, etc.  I 
think it just asks to save the file.

I think I replied this in an earlier mail.  But, either way, hope this 
helps.

Cheers,
Mohit.

I have found that the way that works for me (I use this for PNG) is to 
serve it up with the mime type 'application/unknown' so that IE does not 
try to interpret what program should handle the information coming down.

Hi Walter,

Thanks for the message.  I am going to almost certainly try to install 
and play with Kete in about a week or so.  I'm developing a technical 
community website (something like the PHP documents site) and this looks 
quite exciting.  Radiant was also a good start towards that, but I feel 
(and this is baseless) that Kete + Radiant might be very very powerful!

Cheers,
Mohit.

Hi Tim

That's a fantastic list of things you've created.  Any chance that I 
could urge you to add it to the Radiant CMS Summer Reboot Documentation 
[1] project?  It may go in as something like "Does Radiant have what I 
need?"

Cheers
Mohit.

This looks very interesting and very promising!  I would like to try 
this.  I'm using Radiant CMS for a few things and feel that Kete seems 
to offer a lot of compelling features for knowledge base portal development.
