Re: Stress-testing SQLite -- degradation on big selections

 Thanks in advance for sharing your experiences with large data sets if
 SQLite.
 
 
 Hi Richard,
 How many tables and how many columns per table (on average) are you
 talking about?
 
 Probably just a single table, with about 20 columns.

Okay this answers my question.

So now I can tell you Richard, ONLY because of columnar format,
Valentina DB can do some operations 20 times faster of any ROW-based DB.

And if multiply this to other features of Valentina you can become
With Valentina 20 *4 * 2 = 100-200 times faster.


 If not, then that's not so much a problem.
 
 Good to hear.

Very not true :)

When you talk about speed and time, all is relative.
You need talk about ABSOLUTE numbers instead.
   
For one person/project/app 10 sec for search is very fast,
For another this is incredibly slow.

Richard, when you say, I NEED SPEED, you must say:
  I want query in 100 sec or in 0.01 sec

Only having this info, people can advice you.

 
 What's the potential return record set count on a typical filter?
 
 It'll vary, and in my own tests that seems to be the only bottleneck
 with SQLit; queries that return little data are ultra speedy, but once
 we get into large amounts of return data I see the hit.

Exactly Richard. 

This is named degradation of DB on grow of

A) records number in table(s)
B) records number in the RESULT

Yet from 1996 year, when I did my first benches of Valentina against
 FileMaker, 4D, Access, mySQL, ...

And this very first thing I have found also.

Most dbs if not all, have powerful degradation when recs number grow.

Also exists some special N related to RAM of computer. Below this N dbs go
yet more or less nice. After N degradation can go by jump x10 worse.

With Valentina this N was much higher in the same RAM, because of much more
compact db format for data. And after N it was very good yet.


For example, if for most dbs difference in time between 50 and 500,000 recs
in result is huge, for Valentina it is almost flat.


 
 I'd be happy to do some stress testing if you can give me some details.
 
 Thanks.  Don't knock yourself out; I'll be continuing with my own tests
 here, but if this sort of thing passes for entertainment in your house
 then of course I'd be grateful for any details you turn up.

if you

the variable tKeyboard will contain something like:

you can drop the unnnecessary things by

delete char 1 to (offset(apple.keyLayout.,tKeyboard) of tKeyboard
delete char (offset(—,-1)) of tKeyboard

... and tKeyboard should contain SwissFrench (on my Mac, at least)

I'm to lazy to check what mean the remaining stuff; perhaps something useful...

How to reorder lines in a list field

2010-10-30 Thread André Bisseret


Bonjour,

I am trying to get a list field where it would be possible to reorder  
the lines.

(is there somewhere any tutorial or any solution on this?)

I started from a script from Éric Chatonet that allow moving lines  
from field1 to field2, modifying it to drag lines in one field only.


I succeeded in a test stack:  in a list field, all works as expected  
with a dragImage).


My problem is that when I put exactly the same script in a field of an  
app. I am developing, it does not works any more:
The dragged line is deleted when releasing the mouse (except if I drag  
outside the field and then back in it: then that works


I am fighting with that for hours now, and can't find what is wrong.

My last surprise is that if I don't create (set) any dragImage, then  
all works as expected.


I am getting crazy
The worst thing is that the same script works well in a field on my  
test stack and not on the field on my other stack (the two fields have  
exactly the same properties).


Any idea on what could be wrong?

Thanks a lot in advance

Best regards from Grenoble

André

 physical keyboard?

I am someone who uses and analyses a lot of games, where keyboard features are 
often mapped to position instead of char-output. Basically the answer to your 
question is no. Sure, there are ways to find out some information about the 
layout, but keybord layouts are not normed in any way beyond thats how they 
always did it.

A simple example is the difference of an older swiss-german mac layout versus 
an american layout (those being the two i have here right now):

for swiss layout vs us layout:
the row that starts with q has one more key at the rightmost position
the row that starts with a has one less key at the rightmost position
the row that starts with z doesn't start with z, it starts with , and then 
continues with y (y and z are always switched in german layouts vs us layouts).
The return key is not a double key in width, but instead a double height (with 
some adjustment to width because the rows are shifted slightly compared to each 
other, producing a hook-looking key)
Instead of a second alt key to the right of the spacebar, there's a return key 
on my ibook (newer macs don't have that anymore)
Obviously a lot of chars are mixed and moved around, for example shift- and 
then the numbers at the top (from 1 to 0):
swiss german: +*ç%/()=
usa: !...@#$%^*()

now, on my windows pc (swiss german layout), there's an alt-gr key to the right 
of the spacebar, which allows the typing of funny chars like |,€,¢, etc.
there's also a windows and a menu key, which macs won't ever have (they have 
the command key instead).

And that's only comparing three keyboards that I have here. If you want to 
catalogue all keyboard layouts of the world, I'm sure you could sell big buck 
licenses to all the game developers who do this stuff on a far less 
sophisticated ground: Every user can adjust his preferred layout nilly willy, 
and only the most often seen ones are (maybe) build in. 

And then there's dvorak.

For example Starcraft 2, one of the biggest budget games of the year, has fixed 
layouts to reduce cheating vectors. these layouts are always bugged for a 
certain percent of the community, and the answer to those is: memorise or lose 
the game.

Re: How to reorder lines in a list field

2010-10-30 Thread Björnke von Gierke

I can't help you with code from someone else that I have no intention of 
looking at. Most likely a mouseenter or mouseleave doesn't trigger, no clue. 
For reordering lines, there's no build in way, and there are many possible ways 
to do it. Here's mine. It uses just the list field, and is probably a bit 
simplistic (no floating line/drag image following the mouse cursor). But it 
works for a single selection list field.

on mousedown
  put the selectedText of me into myDrag
  put the mouseLine into mySelection
  repeat while the mouse is down
put the mouseLine into toSelect
if mySelection  toSelect and toSelect   then
  put the scroll of me into theScroll
  put me into theText
  put word 2 of toSelect into LinetoSelect
  if lineToSelect = the number of lines of me then
delete line (word 2 of mySelection) of theText
put return  myDrag after line -1 of theText
  else
delete line (word 2 of mySelection) of theText
put myDrag  return before line lineToSelect of theText

It seems in my initial tests that the time it takes to get data through

Is this a known limitation of externals, or is this just a case of false

RE: Stress-testing SQLite

 many of the data stores for the major apple apps use sqlite. 
 it's a petty robust single user data store. 

Of course I don't need to expand on what Ruslan will say about Valentina,
but I will say that there's a right tool for each job, and others that sort
of work but aren't optimal. I can use a brick or the butt of a screwdriver
to drive a nail into a piece of wood. There are reasons why, for example,
AOL Europe, Nikon Corporation and others that may not be named chose
Valentina over something like SQLite for their specific projects. 

I can say for certain that developers do not pick Valentina because it is
free or in public domain :-)

SQLite is a functional, single user database, but the database market is
filled with alternatives. Its worth looking at Ruslan's emails recently
asking about changing schema to see where even his expectations for SQLite
were different.

SQLite has its place in development, and there are good reasons to use it.
But like evaluating any infrastructure technology, you have to consider what
your long term plans are and what your clients are likely to ask for later.

 32TB db limit according to this:
 
 http://en.wikipedia.org/wiki/Comparison_of_relational_database
 _management_systems#Limits

Charts like this, especially on Wikipedia should be taken with a grain of
salt. Feature comparisions (yes/no) I can appreciate, but when it comes to
capacity and performance, that's a bit different. There are some database
vendors that in their EULAs state you cannot publish performance data, and
also have sued some who have done so. 

My advice if you are considering entering a software product market that is
as mature as the database market - save yourself the hair loss and choose
another ;-)

In all fairness to all the databases in that list (Valentina can act like a
relational database, but it isnt there because it's a columnar database),
for many of them, the limits are theoretical and based on limitations of how
volumes work in file systems and operating systems.

There's often a vast difference between theoretical addressing limits

There are some database vendors that in their EULAs state you cannot

A curious limitation.  Which ones?

Re: How to reorder lines in a list field

2010-10-30 Thread FlexibleLearning

A very nice handler, BvG!

As written it needs the traversalON to be true to display correctly. A minor
change to one line and it displays correctly whether the traversalON is
either true or false...

on mousedown
  put the selectedText of me into myDrag
  put the mouseLine into mySelection
  repeat while the mouse is down
put the mouseLine into toSelect
if mySelection  toSelect and toSelect   then
  put the scroll of me into theScroll
  put me into theText
  put word 2 of toSelect into LinetoSelect
  if lineToSelect = the number of lines of me then
delete line (word 2 of mySelection) of theText
put return  myDrag after line -1 of theText
  else
delete line (word 2 of mySelection) of theText
put myDrag  return before line lineToSelect of theText
  end if
  put toSelect into mySelection
  lock screen

Thanks Scott for your reply.

Indeed, I know your very nice GetInLine (which was pointed out by

But, actually, I am trying to learn using the drag and drop features  
of livecode.


In fact starting from this tutorial, I have got a script which runs  
nicely in a test stack I made.


My problem arises when I put the same script in a field of an app. I  
am developping:  it does not works there.

Even If I copy the test field on my app. it does not work.

If I copy the field of my app. (which has the same script) on a brand  
new stack, then the script works!!


So the problem comes from the stack of my app.

I can't find any idea about what  could hinder the field and its  
script when it is on my app.


Thanks again for your reply

Re: Stress-testing SQLite -- millions records? Use Valentina DB

2010-10-30 Thread stephen barncard

Yes, I've been waiting for Ruslan to chime in here.   Valentina has been the
*elephant in the room* in this discussion and I find it slightly odd that
Richard (no newbie in the Rev world) hadn't considered this product for his
project.

If I were starting a new db project right now and wasn't forced into mySQL
by the client, I would take a serious look at the Valentina  ADK.

Right now they are offering the beta of Valentina Studio Pro for free ( and
there's a free Valentina Linux server for non-commercial use - Richmond?)

geesh, I just talked myself into finally trying this product myself.

I don't see any other db company bending over backward to serve Rev/Livecode
users.   And we even have Ruslan on the list here

  I don't need relationality, so for me SQLite is an option but only an
  option; I'm happy to consider other options as well. (Yes, it has to be
  SQLite rather than MySQL, because it needs to work embedded with a
  commercial application).

 Valentina DB is faster 100 times of SqlLite, mySQL

 And can be perfectly embedded into commercial application because it is
 royalty free.


  Have any of you done stress testing on SQLite to that degree?
 
  I've tried finding even anecdotal data on the web for SQLite limits, and
  while I can find citations of theoretical limits I haven't come across
  real-world usage stories of data sets that large.
 
  Should I be confident in SQLite as a storage solution for that?  Should
  I be scared?

 SCARED :)

  Thanks in advance for sharing your experiences with large data sets if
  SQLite.

 You need Valentina DB.

 Okay you need 5K for each record.
 How many fields?

 Let me remind that Valentina has columnar format.
 This is huge advantage.

 Also Valentina can give you not only SQL way but NON-SQL way,
 Which can be additionally 10-20 times faster!

 --
 I can tell you store, that Valentina was tested for AOL Europe by their dev
 team. Against Berkly,  mySQL, postgre, and other dbs. SqlLite even was not
 in game of course.

 Task was so simple. Table has 2 fields {URL, PictureBannerAd }

 So when somebody ask for a WEB page, it needs find banner to be shown.

 As they told, e.g. Berkly have give 100 faults per time (min our hour I not
 remember now).  Other dbs also. Fault means that banner was not found  by
 DB
 in time less of timeout.

 Valentina have give them zero faults.


 Let me underline this very important feature NON-SQL-ness of Valentina.
 As well as very powerful SQL.

 Today is very modern stream talk about how SQL DBs are bad, and how cool
 are
 NON-SQL with Key-Value.  Guys, be happy, Valentina is perfect for both
 tasks. :-)

 If talk about details, in V4REV API (and most others Valentina ADKs) you
 can
 use not SQL way to do searches and sortngs using
   VField_FindValue()
   VField_FindRange()
   VField_FindLike()

 And other similar search methods.  They are really FASTEST POSIBLE way.

Re: Stress-testing SQLite


Interesting find:

  The Truth About the TPC
  ...
  For example, one reader asked, Why does the TPC organization
  only test commercially licensed operating systems and databases?
  My presumptions would lead me to think that a non-profit based
  organization would be benchmarking anything they could get their
  hands on. An example being, why don't they test postreqsql or
  mysql on a Linux platform?
  ...
  However, the TPC doesn't have the power to run benchmark tests
  on a database platform without the approval of the database
  vendor. In fact, with the exception of IBM, most major database
  vendors include in their license agreements a clause that forbids
  the publication of benchmark information without explicit
  permission. Here's the clause from the SQL Server End User
  License Agreement (EULA):

 e. Benchmark Testing. You may not disclose the results of
 any benchmark test of either the Server Software or Client
 Software to any third party without Microsoft's prior
 written approval.

  Oracle, Sybase, and Informix each have a similar clause. These
  clauses are generically referred to as DeWitt clauses. David
  DeWitt was one of the founders of the Wisconsin Benchmarks,
  which were first published in the mid-1980s. At that time, the
  Wisconsin Benchmarks published less-than-favorable scores for an
  Oracle database, and Oracle wasn't happy with the negative
  publicity. Oracle added a clause to its license agreement
  forbidding unauthorized benchmarking, and most other vendors
  followed suit.

Indeed, very interesting - this came onto my radar when it was reported that
one of the companies sued someone for doing a comparision of the big iron
databases.

Oracle, IBM and MS are big money players with massive legal departments and
super huge budgets for their products. You'd think they'd simply kill off
smaller companies, leaving only themselves and open source databases. But
the only ones really killed off are those that do not have any really
differentiating value. For us, I think half of the picture is performance,
the other half is platform and extended value support.

Re: [OT] Browsing the internet... It is safer from Linux?

2010-10-30 Thread Mike Bonner

If you're only wanting to browse, and are not sure a particular site
can be trusted, you might try using a live linux cd and browse from
there. Might not hurt to unmount your hard drive partition if you do
this just as an added layer of protection. Some live cd's auto mount
what they can find, some don't.

I run clamXav on my mac just because i was curious, but have never
found anything with it.

As far as downloading updates with linux, if you download something
with a trojan, and transfer it to your windows machine, you can still
get nailed unless your windows AV or malware scanner picks it up. In
many cases it boils down to whether you believe the site you are
downloading from can be trusted or not.

I ran windows for a lot of years and didn't have too much trouble. Was
surely not trouble free by any means. In some ways, I think its worse
now. Cross session hijacking, clickjacking, browser exploits. With
things moving closer and closer to being cloud based, I suspect things
are going to get really really ugly before they get better. Just my
opinion though.

my Windows computers from the internet and
use only Linux to browse and download updates.

In truth,
How safe is using Linux browsers in the internet?
Most exploits seems directed to Windows and Mac users
but are Linux users really exempt from these risks???

What are your first hand experiences with the most common
security risks under the Linux platform?

RE: benchmarks

Hi Mark,

I can't find the article now - doing a search on the company name + various
key words brings up loads and loads of their lawsuit vs Google and not much
else. I recall reading about it when it was news, which could easily have
been in 2006 when DeWitt was such a hot topic.

I did find an interesting article on DeWitt clauses though - focusing on the
tech world but a surprising number of them outside of it:

http://www.allbusiness.com/technology/computer-software/4092403-1.html

 And the Center for Internet Security has benchmarks available 
 from their website, as well as a benchmarking tool for 
 members to let you roll your own.

Do you know if these benchmarks are for more than (just) security?

Swapping scrolling text for regular text

2010-10-30 Thread Mark Smith


I have a sort of dumb question. I have a stack with about 12 cards that has a
text field on it (part of a background group). I would like to change this
field to a scrolling text field. Is it possible to swap or change the
existing regular text field into a scrolling one without loosing the
existing text entries? (or is the only option to restart from scratch).

Thanks

-- Mark

Mark - all you need to do is select the field and enable its vScrollbar
property in the property inspector.

Regards,

Terry...
