OT: Problems with UDP traffic with Barak
Hi, Sorry if I ruffle anyone's feathers, it's not my intention to do so. I've been using Barak Internet with Hot Cable for over 3 months. I have an Edimax 4-port router (the wireless part is currently deactivated), with some PCs and a Zyxel VOIP adaptor connected. Everything was working fine until a couple of weeks ago when I noticed that VOIP traffic was suffering in the afternoons and evenings. This would range from moderate levels of break-up to the inability to initiate a call or even get a dial tone (i.e. SIP registrations were failing). The device is registered with an Asterisk co-located server in the US, and you can plainly see the registrations starting and ending in the Asterisk console. Further testing also revealed that Skype under Windows XP was also either performing badly or not at all. I tried a number of things to eliminate my own equipment. I tried resetting all devices. I tried removing all the PCs from the router, and as I said above I deactivated the wireless. I also tried removing the router entirely and using the Win XP PC with their own L2TP dialler software to connect. I didn't try plugging the VOIP adaptor directly into the cable modem because the VOIP adaptor can't speak L2TP, only PPPoE/PPPoA. Nothing made any noticeable difference. Here's my symptoms: * Up till about 10 am or 11 am, moderate to good VOIP/Skype performance. * From then on, poor performance to completely unusable. * Incoming seems to be worse than outgoing. That is to say, when I can get the VOIP working, more packets seem to be being lost on the way to me than on the way out. * TCP (both up and down) seems to be completely fine. I seem to be getting the full 1500/512 kbps that I should be getting. And pings are also solid. Yesterday I did some testing with a friend in the US who had some UDP tools like traceproto and hping3. We managed to trace it to a Barak router a couple of hops from me. Unfortunately, they seem to have changed their routing tables today and the addresses are all different. The guy I spoke to at Barak tech support today wasn't very helpful. All he would do was verify that I was getting the proper upload speeds, and insisted that they weren't blocking any UDP ports. I couldn't seem to persuade him that packets were being dropped, and the fact that it was all fine up until a couple of weeks ago seemed not to mean as much to him as it does to me. So now I'm wondering if I'm crazy or if anyone else is having similar issues. I figure that if I can find other users who are experiencing similar issues, it'll be easier to persuade them that they need to take a look at their own equipment. Any suggestions anyone can give would be most helpful.

The device is registered with an Asterisk co-located server in the US, and you can plainly see the registrations starting and ending in the Asterisk console. The whole point of UDP, is that it's basicaly raw IP. IP was designed as a packet routing protocol, you stuff a packet in here and it comes out there. When, or if, it comes out, in what sequence it arrives and the condition it arrives in are anyone's guess. Since IP is a dynamic routing protocol, it's possible for packets to arrive out of sequence, incomplete, or just plain messed up. That's why TCP was developed, UDP had so many problems that it was considered unusable for sending any data that mattered. Some protocols written on top of UDP were designed to accept this and do their own error and sequence checks. Most VoIP protocols use it because of the lower overhead. Retransmission is not an option for VoIP especialy for international calls, by the time the packets would get retransmitted, it would be too late. It's just better to drop them and wait for new ones. Here's my symptoms: * Up till about 10 am or 11 am, moderate to good VOIP/Skype performance. That's normal. * From then on, poor performance to completely unusable. That's also normal, but usually it starts later in the day. * TCP (both up and down) seems to be completely fine. I seem to be getting the full 1500/512 kbps that I should be getting. And pings are also solid. From where? I get my rated speed from my ISP to my router all the time too. It has little or no effect on what I get to anywhere else. Yesterday I did some testing with a friend in the US who had some UDP tools like traceproto and hping3. We managed to trace it to a Barak router a couple of hops from me. Unfortunately, they seem to have changed their routing tables today and the addresses are all different. Probably because they just merged with Netvision. I assume the first thing they are doing is to combine the networks. So now I'm wondering if I'm crazy or if anyone else is having similar issues. I figure that if I can find other users who are experiencing similar issues, it'll be easier to persuade them that they need to take a look at their own equipment. I suggest you wait a few days for the dust to settle. I just did an echo test using Free World Dialup and a Linksys PAP2. I have a 5m/256k HOT connection with Netvision. No problems or packets dropped. Geoff. -- Geoffrey S.

Give up on transparency altogether or can you suggest something else? The problem is with alpha transparency, not PNG transparency. GIF does not support alpha transparency, but binary transparency, which is widely supported by all modern browsers (yes, IE too..). Transparent GIF might or might not work for you. If it doesn't work, and you still need transparency, go for PNG alpha transparency with your favorite hack for IE.. --yuval pgpj0CnqAlPmE.pgp Description: PGP signature

Digital Photo Manager
Hi, Like most people with a digital camera, I've amassed thousands of photos on my hard disk. Viewing them with xv, my trusty but long-in-the-tooth image viewer, has become unwieldy, if not damn near impossible. I also really miss the possibility to *search* on my photos without going over all the pictures every time - something which I find myself doing very often for various occasions. So basically, I'm looking for a photo management application for Linux. Something like Picassa would have been a good start, but not good enough, as you'll see below in my wish-list. I also tried f-spot and it's not good enough. So I was wondering, maybe the wise people of this list can recommend a good photo management application for Linux? Here is my wishlist for a photo manager. In fact, I'm wishing for these features so much, that I'm itching to write one myself... (but I hope it doesn't have to get to that). 1. I don't want any sort of vendor lock-in, forcing me to stay with a certain application once I choose it. Therefore: a. The photo manager should be able to work on a normal filesystem hierarchy of photos, neither ruining it nor making a complete copy. b. Whichever metadata the photo manager wants to save (like tags - see below) it should save in an open, simple and potentially-standard file format. Not in an uber-complex database, and not (given 1a) to the photo files themselves. Picasa and f-spot both fail in this regard - I didn't manage to extract the meta-data I save in them to any readable format. 2. The application should allow me to easily and quickly browse all my photos in different sizes (like in picassa). 3. The application should allow me to add textual descriptions and tags to pictures, and have a full-featured text search engine to search these. For example, I can add to each picture tags specifying the persons in the picture, location of the picture, and so on, and then, for example, search for all pictures containing a specific person. F-spot's tags are a good start, while Picassa's folders are a worthless disaster. But remember 1b - these tags need to be saved in a simple format, not in a propriatary database. I don't want to spend hours to type tags in, and then be unable to use them if I switch software. I don't loose my C code if I switch from VI to Emacs! 4. Bonus points for some automatically-generated tags based on dates, camera, colors, and other information obtainable from the picture files. 5. I want a digital photo manager, not a digital camera manager, and not a sophisticated photo editor - for which separate applications are available. 6. Bonus points for an application that doubles as (or is only) a Web- application - allowing others to log in to the application over the web, and see my pictures according to access controls I specify (e.g., I can say that a specific person can only see pictures with some specific tag). Extra bonus points for a Web application that can host picture collection uploaded by several users, allow them to manage their own photos and others so see only some (as above), and perhaps help with the tagging task. I'm looking for something small, though, not something capable of running a huge site like as flickr.com. So, can anyone point me to a good (according to my definition of good ;-)) digital photo manager? Or shall I be forced to write one myself? -- Nadav Har'El| Tuesday, Aug 7 2007, 24 Av 5767 [EMAIL PROTECTED] |- Phone +972-523-790466, ICQ 13349191 |A fine is a tax for doing wrong.

Re: Digital Photo Manager
I wonder if I'm the first one to say: http://gallery.sf.net one of the most amazing webapp I've seen. Gallery1 works on raw filesystem + data file, Gallery2 keeps the data in DB (mysql but probably others as well). I think it fits MOST of your requirements. - Oren On Wednesday, 8 August 2007 00:47:24 Nadav Har'El wrote: Hi, Like most people with a digital camera, I've amassed thousands of photos on my hard disk.

Picasa and f-spot both fail in this regard - I didn't manage to extract the meta-data I save in them to any readable format. It uses SQLite to store its own meta data and I think it can also store tags in standard EXIF format if you wish (or at least there were discussions of such an option on the Digikam mailing list). Basically having the data in a documented SQLite database means that you are not locked in and can add your own stuff. Also it has support for plug-ins (with many plug ins already available) so you should have a way to add your own stuff. 2.

I want a digital photo manager, not a digital camera manager, and not a sophisticated photo editor - for which separate applications are available. Check. I just mount my camera's card through the card reader, import to Digikam using import folder and manually erase the photos from the card. I think it can manipulate media connected through USB directly (e.g. connect your camera through USB cable and use the special communications mode to talk to it) but I like the manual mount + copy approach, not the least because it saves on camera batteries and I think it's also faster as I'm not sure my camera (Canon EOS 350D) supports USB 2 at all. 6.

That's one thing I miss in Digikam. I currently use Gallery2 which imports photos from the Digikam folders. Gallery has an option to link to existing files so it doesn't keep another copy of the image. It can manage multiple users with different levels of access defined per image or per folder. Extra bonus points for a Web application that can host picture collection uploaded by several users, allow them to manage their own photos and others so see only some (as above), and perhaps help with the tagging task. I'm looking for something small, though, not something capable of running a huge site like as flickr.com. That's Gallery2, not Digikam. Digikam's developers are pretty responsive and supportive. --Amos
