Have you seen my rant on GPLv3 and the people whining about it? ;)

Making it harder for the spammers...
Our Antispam configuration needed an update - too many spams went trough. Beside a general configuration renovation, we today added SPF and Greylisting. Especially greylisting (using postgrey) is realy cool - you can immediately see how the spammers are being trapped. I am not sure how long it will take until they catch up, but I guess we will have at least another half year (probably year) before the next renevation is necessary ;)
I have also published SPF records for our domains. Some of those that are never be used for sending mails are currently being worked on. That won't save us spam (at least not much), but it will definitely be a plus for our reputation, as we are now less likely to become faked sender addresses in spam and malware.
LOL - this post was spammed, too. Blogger's system didn't allow me to delete the spam comment, so I simply removed the post. The original post was dated September, 12th 2005. Maybe I should have dug a bit more why blogger didn't allow the deletion, but I had simply no time for that...

spf records for hq.adiscon.com...
I've finally begun to adopt spf records for our domains. As a test bed, I am using hq.adiscon.com, so any trouble will immediately follow to my mailbox. If all goes well, we will change all domains to include spf records. This is especially interesting for those domains that will never send email. Blocking them via spf will mark worm and spam mail with them as invalid - which is definitely nice ;)

phpLogCon is back!
Remember phpLogCon? It comes with WinSyslog and MonitorWare Agent, but it is what I call one of our "hidden treasures". And it is hidden not by design ;)
In my quest for a better syslog system, I have revived phpLogCon, a syslog web front-end. phpLogCon is around for quite a while. I think it was Adiscon's first try at open source. It was written primarily as a front-end for the MonitorWare product line. At the time of the initial development, MonitorWare were commercial software only. In the mean time, the line has evolved, now including both commercial Windows software as well as free apps for Linux and Unix. phpLogCon is kind of a bordergoer. While it is open source (written in PHP), we also distribute it together with the commercial Windows applications. Consequently, its platform targets include both Windows and *nix.
When we started with phpLogCon, we thought that the open source community might use and adopt it to other database schemas, for example as written by syslog-ng. As it turned out, that was not a valid assumption - mostly because we did fail with easily distributing the sources widely enough. We also managed to really hide the tool - nobody ever knew about it - well, of course, beside customers with the commercial tools. ;)
The rsyslog enhanced syslog daemon changed the usability of phpLogCon greatly: now, everybody could use the default schema (as rsyslogd knows how to write it). Some folks began to notice phpLogCon, because rsyslog pointed to it. But it still did not receive too much attention and still was well-hidden.
This has changed now. I have set up a new web site for it at http://www.phplogcon.com. This one is now set to become a great information and community site, where the old one was ... contentless. Technically, I have picked up the sources as well and I am currently in the process of reviewing and cleaning them. While it works well, the design is a bit older and a brush-up is definitely due. I expect this to happen during the next weeks. An aboslute good thing about it is its relationship to the MonitorWare family. So it can also very easily handle windows event log data, for example. phpLogCon is a good tool today, and I hope it is the best of its kind by the end of the year.

Finally, Adiscon's position on Linux is online...
It looks like I needed to do some web updates myself. So I have finally managed to write down a quick sketch of Adiscon's linux activities, hopefully clarifying the policy to our customers.
Besides that, it was quite unfortunate even speaking at Linux conferences while the corporate web site did not even mention Linux at all. Well, that has changed now and I think we will have some further very interesting things upcoming.
Change in software distribution policy
Today, we have made a very important announcement: The NewsMerge product is now given away totally free. We made a similar move some time ago when we offered the logger tool free of charge. However, logger is a little bit like "advertising" for the MonitorWare product line. This does not apply to NewsMerge. The basic idea here - and eventually in other things to come - is that we give away the product for free but charge for support. Especially for products that do not require considerable additional development, I think this is a fair offering to customers. In general, many are happy without ever contacting support and they go away totally free. If someone needs a helping hand, we offer it, but charge a little to feed that hand. Sounds fair to me...

Our Linux efforts are finally taking off...
... at least I hope so. If you look at my syslog blog, you'll see that rsyslog is now close to fully support tcp syslog, which most probably means it also is close to a stable release.
Google Page Rank being restored...
Very interesting... Google has become very quick. As I mentioned in my past posting, we had messed up with out page titles resulting in massive page rank loss. We began to restore the correct titles, and now, just some days later, Google already has the new pages in its archive and the ranking has considerably changed. For example, one page went up from position #43 to the #3 on one of the search words (the site in question is www.winsyslog.com, but it is true for some other sites too). I have to admit I am a bit surprised to learn that just the title change makes *such* a large difference. Maybe it is because we are otherwise well-linked, but shouldn't Google be able not only to judge the title? Maybe they think it can not be modified that much, but nowadays I know many people who do not care for the title at all. So, in practice, it is very easy to optimize the title without hurting your readers...

Web Pages and Search Engines...
Sometimes bad things simply happen ... and somehow remain unnoticed. Some time ago, we upgraded our web pages to php, so that we are not stuck with IIS. During this upgrade, the pages were also redesigned. As it looks nicer, all page titles where shortened, a really bright idea. What was overlooked was that the page titles were carfully crafted and optimized for the search engines. This new "feature" (short titles) did slip our attention. Some time ago, I began to wonder why our search rankings went lower. Unfortunately, at the same time Google changed its ranking algo, and I thought it was realted to that (due to our site structure, we look like a link farm - this is not intended but I thought we received a penalty from Google). During some periodic checks, I now noticed the issue with the titles. Probably this is the real cause of the ranking troubles. Anyhow, we are now restoring the orginal titles and will see what happens in 3 month from now. After all, this is a nice experiement - though not intended... ;)
