Except that it excludes all of us that don't use facebook from those discussions, which seems like a high price to pay for a formatting change.

It's the > distributed model that's died. But that is just the "story of the internet". It has happened to (almost) all services on internet. Even e-mail, traditionally a very distributed service, is now mostly offered by a few central sites like gmail.com and outlook.com/hotmail.com. Sure, in implementation those central sites still often are distributed (being hosted in many different datacenters on many servers all serving the same domain name), but it no longer is the big peer-to-peer network that it once was. This also explains the slow take-off of IPv6: there is rarely a need anymore for a different address for everyone. Rob

E-mail clients

Hi guys, Could you please check if your email clients do support threads properly? At least some of you are using ones that do not answer in a same thread but create a new one. For me it makes this list unreadable and a whole mailbox cluttered. I'm looking mostly at (random order, just what I've came across) Daniel Curry, Steve L and Rob Janssen, but it's important that we all keep the high standards ;) -- All the best Paweł SQ9PID

Re: [44net] The Death of Solaris

I was working at Sun Micro system with Sunos 3.2 and up to Solaris 4.x. That thing I did not like about 3.2 and 3.5 is that you had to mount the ND partion user home directory to fixed a problem. There was no CD directory command. -- Daniel Curry California American Legion Amateur Radio Area 2 Commission and Chairman.

The Death of Solaris
by Brian Kantor 08 Sep '17

08 Sep '17

For those of you who are or have been users of the Solaris OS, you should find the following article interesting. Among other things, it once again points out some of the advantages of open source. http://dtrace.org/blogs/bmc/2017/09/04/the-sudden-death-and-eternal-life-of… I mention this because there are those who have the impression that 'amprgw' is running on Solaris. It is not; it never has. It ran on the predecessor, SunOS, for some years, but has been running on FreeBSD for a long time. - Brian

Lin, Some time back I picked up a pair of Gemini G3 Dataradios on ebay, hoping to be able to use them. I quickly learned they really cannot be used point to point, and you need the expensive base station to act as a controller between them. I swear I have read that some models of the radios are capable of point to point/ peer to peer use. Do you or anyone else know which models would be good candidates for such a thing? I ended up giving them to a friend who documented them the best he could: http://www.qsl.net/n9zia/gemini/index.html

This is of course what I had in mind. We don't have any mountains here but we have a 3cm ATV repeater at 220m in a broadcast tower transmitting a DVB multiplex where we could use some bandwidth (or e.g. the bandwidth remaining after the several variable-rate encoded ATV channels have had their share) to transmit IP over DVB. Both broadcast/multicast traffic (like IPTV streams from the repeater) and traffic to a single endpoint (after all, we do not hide traffic from eachother). The return channel could be much slower indeed, depending on the kind of traffic and the required return traffic. Maybe even a 9600+ baud packet link, or one of those newly developed 70cm links of about 400kHz width. At the moment the repeater is not operating, but we are working on getting it back on the air.

While I applaud Ron's experiments, it would have a very long road to becoming something practical for the masses. Heck I can say the same for the NWDigital radio. They have been trying for quite some time to make the thing happen. I fear by the time either would come to fruition, the whole market / tech landscape could be different. (I.e, 56k is not as appealing at the price point as it was 10 years ago when they started, etc) As for the ARRL, I am the only one who pounces on their staff virtually every chance I get (at ham fests and by email), about getting some of these changes though their heads? I think a coordinated approach, can help our cause. In addition, anyone can make comment directly to the FCC. How seriously they take things without someone waving money in their face is a whole another issue. I wrote this paper quite some time ago, that covers quite a few of the issues: http://www.qsl.net/kb9mwr/projects/wireless/70cm-ATV-HSMM.html Basically they way I see it, one has three ways to experiment: 1.) Pay for/file for a STA, which gives you 6 months 2.) Include some element of image transfer, so what your doing can be classified as an image transmission rather than data. (most logical/easiest to do) 3.) Develop a data mode that uses multiple carriers, as each carrier can be 100 KHz wide. #3 is something I joked with friends about when I was in high school. That was long before SDR, so we envisioned taking a few TNC's and radio's on different frequencies, RF combiners and tons of filters to make it actually work, and from there channel bond/load balance all the data streams to achieve better throughput. Do we have anyone who holds a ARRL position on this list? Steve, KB9MWR Mark Phillips <g7ltt at g7ltt.com> wrote: > >"Maybe someone at ARRL ...." > >Ha!

> Setting up a NNTP server is easy in JNOS. Pretty tricky on Linux... Actually it is easy, just "apt-get install inn" and editing a couple of config files. Of course you first need to understand the architecture of USENET and the INN software but there is documentation available. It is comparable to the complexity of configuring JNOS when you have not done that before. Rob

> USENET is obsolete. Don't waste your time on it. Well, not as obsolete as a mailing list... A closed news server would be much more convenient to use for discussions like this than a list... (and of course you could run it on a Raspberry Pi :-) Rob
