Re: [PD] coll object
coll uses a special format to store its data, it always uses an ID, then a comma and then the message content. this has some advantages (sorting, lookup) but does not work with all textfiles. I suggest to use textfile or messagefile. or, if you want to use coll, then look at the fileformat and save your textfiles, for example like 1, first message; 2, lalalal; 3, and so on; 4, 123 40734 9831 1320487132 132; marius Donal Carey wrote: Hi all Apoligies if this is not the correct place for asking these sorts of questions.

Re: [PD] kml files
If I'm doing it right, single precision float should be able to represent latitude and longitude to within about two meters. If more precision than that is needed, you'll want to use tr to change periods (as well as commas) into spaces so that you get lines like: -112 3348783983763 36 1514008468736 100 Then filter for whatever range of integer latitudes and longitudes you're actually looking at. Then you should get 1 degree x 2^-24, better than a centimeter. cheers Miller On Thu, Dec 13, 2007 at 11:51:14AM -0500, marius schebella wrote: hi, google earth uses a special format to save geo information data (kml files).

Re: [PD] Inlet Proxy object example
Thanks for this, it looks like a nice, clean example of how to do this. Very valuable. I'm sure I'll have questions about this stuff. For example, right now I am in the process of figuring out how to parse the object arguments for ?, then dynamically create an inlet for each ? it finds. I believe the standard is to use ?? as the escape mechanism, so that has to be included as well in the parsing, but that's not too hard. I am thinking that one proxy class will be enough, then I just make one instance of the proxy class for each ? found, thereby making an anything inlet for each SQL placeholder. I guess the proxy class should include the pointers for making a linked list of proxy classes to store all the instances. I was trying to figure out how this is done in [expr], but that code is super strange, so no luck yet.

Re: [PD] honk abstractions
Johannes~ These objects are very nice, and would be a great contribution to Pd-extended! Thanks so much for sharing them. One thing that would be helpful for you to do is to create a simple object-help.pd file for each object. The reason this is preferred over the help being within the abstraction (which is still a nice thing to have) is simple. When you open the abstraction by itself, it doesn't have all the nice functions of a loaded abstraction, rather it is like a normal patch. To really show off how someone can use your abstraction (and give them a nice point of departure to cut/paste into their own projects) it is customary and appreciated to write a simple wrapper patch (*-help.pd) that implements the abstraction in the wild. For instance, I had to create a new file called honktest.pd within your honk folder in order to test out your (very awesome) abstractions. So that's just my own humble two cents (not worth much compared to the Euro as of now). Again, thanks so much for sharing your tools! ~Kyle On Dec 13, 2007 11:04 AM, Johannes Kreidler [EMAIL PROTECTED] wrote: hi list, over the last months, i've been programming a couple of abstractions to enhance faster and comfortable programming in pd. maybe they're useful for anyone else out there. some ideas arent't new, of course, and there might exist similar objects. i called the collection honk abstractions. download: http://www.kreidler-net.de/honk.zip documentation: http://www.kreidler-net.de/honk.html or http://www.kreidler-net.de/honk.pdf some of them require [at least] pd-extended 0.38 help is inside the patches. it contents: GLUE linvert - inverts order of atoms of a list listerize-fifo - like serialize but for symbols, turns a list of symbols into a list, in order: first in first out listerize-lifo - like serialize but for symbols, turns a list of symbols into a list, in order: last in first out mergerize-fifo - turns a stream of symbols into one symbol, in order: first in first out mergerize-lifo - turns a stream of symbols into one symbol, in order: last in first out nbangs - sequence incoming bangs schange - like change but for symbols, outputs its input only when it changes TIME malibu - counts in a certain speed zetro - random metronome MATH noreprand - exactly like random, but without repetitions. outputs random numbers in given range.

That's one reason why I advocate having the core object represent the connection to the database rather than a query.

[zl] acts more like a namespace prefix than an actual class, so, it's really not much less modular than what it could be: most of the time it wouldn't make much of a difference to split it in smaller classes except splitting the help patch into tiny bits with more header and footer than actual content. [coll] needs it like that because the data sits within [coll], it's not functional like [zl] is. Pd's arrays are likewise, but with less methods. Neither [zl] nor [coll] seems to me like they have anything to do with the way to handle multiple connections. [coll] would be relevant if it offered a way to share the same collection across several [coll] objects.

You can't type one in a messagebox, that's all. You can make one anytime with [makefilename]. You can edit a pd file and insert a sufficiently backslashed semicolon and it will appear. Also, a non-backslashed semicolon in an objectbox is parsed as a symbol of 1 character and it is passed as an argument to the newmethod. Calling a newmethod is to send a message. then no one will ever be able to send a semi-colon to [sqlite]/[psql].

But I can see a use for using Placeholders, especially when you have a lot of data to store (and it also kind of vindicates my original idea of putting the SQL directly in the creation args... [wink, wink, nudge...]). This idea of doing this to make this more PD-like I think would be a waste of time, as SQL is pretty simple and a LOT of people already know it. Why create another language? I just had a thought, SQL injection relies on being able to send semi-colons in text fields. This is not true. I have already posted an example in this thread on how to delete a whole table using SQL injection without a semicolon. At the same time, should our external be on the look out for these sorts of things? One of the original ideas was to not give the external any, if at all, knowledge of SQL. Meaning, it wouldn't parse the SQL, nor would it try to do any generation of SQL. It just expects that the user is HONEST (that is what these concerns over Injection are, right), and the SQL they entered is what they meant. These things being said, I am not adverse to the new design model, and I hope to get something up over the weekend. While we can try to protect against various things, those that want to be malicious will do so anyway. Of course, we could eliminate these problems altogether, and just use an embedded database ONLY... (just kidding...)

[PD] Gem, arguments to particle domains.
Hi, all. Below is an excerpt from the help file to [part_source] I found in the latest Pd-extended (stable), describing the arguments understood by the object. --- From here --- domain: one of point, line, triangle, plane, box, sphere, cylinder, cone, blob, disc, rectangle arguments: up to 9 floats, defining the specified domain (like x y z for point, x1 y1 z1 x2 y2 z2 for line, x y z r for sphere, ...). The meaning of the arguments depends -of course- on the domain. --- Up to here --- As far as I know, there is a lot left unexplained in this particular help file attached to Pd, especially on how many arguments each domain likes to eat and what the floats represent. Embracingly, I did not know till a few days ago that there is another API which is the mother of Gems's particle handler and that the arguments are explained in its documents. For example, I've just learned this morning that sphere takes 4 arguments and their purpose seem to correspond to what is said in the API manual. Am I just going through unnecessary trouble because of me not knowing of a manual pakced with Gem, or shall I be taking notes of my discoveries so that I can perhaps commit to the help file? -- David Shimamoto ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] windows latency down to 15 milliseconds
asio4all is certainly a nifty program. I'd like to share a story regarding this application I thought was interesting. -- A few months ago I purchased a MIDI controller by Alesis which came with a soft synth. As far as I know, most soft synths have pages in their manual explaining methods of reducing latency on your sound card. Adjust this buffer, increase value if choppy cause you've gone too far, else just give up and go for a better card... ya-di-ya... Same with this Alsis product? No... The manual just noted links to asio4all as a solution. This application (at least the version I have installed) has extremely political messages in its GUI. I hope it does not effect consumers impressions towards Alesis. -- David Shimamoto I was using my old laptop running xubuntu for a while because the latency time of running pd on windows. My newer Gateway laptop has poor performance with the sound card in Linux, so I have to run windows on it. Before, the lowest I could get it the latency without pops was 60 milliseconds. This was very frustrating, because allot of what I am doing is real-time guitar processing and 60 milliseconds is way too slow to use. But I found a way to get it much much lower. First by using the asio4all driver http://www.asio4all.com/ with built in sound. This makes a huge difference. I have tried other asio drivers, but this one performs incredibly with pd. I cannot say how it will perform on external cards, but on my built in Sigmatel, it works great. Second, by setting windows xp to run pd at real-time priority. You do this by right clicking the pd process in windows taskmaster and setting it to real time. Doing this I can get the latency as low as I had it on Linux, and possibly lower. I haven't tried lower than 15, so I'm not sure ;) But I've played for over an hour on windows with no glitches or pops, well other than the ones I was making on purpose.
