My personal view on things

Bye Bye image spam!

Some might have noticed the increasing amount of new spam that comes as image. This makes it impossible for a spam-filter like spamassassin to filter anything since the content of the spam is hidden as image and the text in the mail is random or some pieces from lord of the rings. The solution? OCR ! There is a nice plugin for spamassassin called ocrtext. This little plugin, among with some other tools will fight spam that comes as image. Also new tricks, like animated gifs which can bypass other ocr plugins, will be recognized by ocrtext. I have only done short testing. But I think next week I can say if it was successful or not since I recently got a lot of image spam, this really pissed me of so I finally decided to do something against it.


Camcorder Problems SOLVED

Finally after so much time it came to my mind to ask in some forum what the problem could be. After a search on google I cam across a german video editing forum, digitalvideoschnitt. I got a reply quite fast and I just tried it out and it worked. The problems seems to be when the camera is plugged in to the source! The problems don’t occur when running on battery! The problem seems to occur because of a ground loop since there are 2 grounds, the firewire and the source. Sounds strange but it works and that’s what counts!


Shell Shock :)

One Week Back to Windows – OSNews.com

One of the things that has always made Unices so popular and admired was the shells out there. In fact, most operating systems today have some sort of a competent CLI interface. This is for two reasons. Firstly, in order to offer a way to automate repetitive tasks. Secondly, because you may expect to login remotely, without having access to a graphical environment. And thirdly, because there are cases when you will simply discard the GUI, like when running a web server.


Camcorder problems

I always had this problem since I have my Panasonic NV-MX300! I do not know how to explain the problem so I will demonstrate it with this movie

Noticed the squares appearing two times at the beginning? This can be only from the camcorder. I do NOT have this on the tape if I play it with my camcorder (the same as used for recording, as mentioned, the Panasonic) on TV I do not have these problems. It can not be from the software, I had this in Pinacle, Vegas on windows and also on the Mac in iMovie and Final Cut so there is no way this could be from software or the OS. Neither could it be the hardware, it occurred on my old PC (1.7GHz), Laptop(3GHz), Mac Mini and on the iMac. I once had to capture a movie from a different camcorder, also Panasonic but a different model and there I did not have this problem. So what is this and how do I solve this? Or is there some external device I could use to capture the tapes?

What on earth did we do to deserve such punishment? This is the late punishment for o-zone it’s music. Thank you o-zone for this. We all waited for it! Really!

I think I have to create a new blog category “extreme stupidity” !

DoS attack?

Yesterday I had to reboot my server after it was unreachable. It all started with nagios sending me some sms, to many process, http doesn’t respond, https doesn’t respond … As I finally managed to try to login it was already to lade, the server wasn’t responding anymore. After a reboot everything was fine again, but not for long. Again from the same many connections to apache where made so I added the ip to the firewall blacklist and now it’s silent again. But this is not a final solution, I made some new adjustments to Apache, now only limited connections/IP are allowed, I tried first 5 but although I wasn’t doing much I got the “Service temporary unavailable” message so I increased it to 10, further have I set the MaxClients count from apache from 150, to 100 and I am thinking of reducing it further, I will have to do a stress test some day. The next step will be bandwidth limitation, some domains are already limited by mod_bandwidth but I would like to solve it different and not with a apache module. Well some information really comes when you need it, a friend of mine pointed me to TC (traffic control) so I will take a look at that, when I have time.


Photo editing

I was just playing around with some features of Aperture after watching some tutorial movies. Now this is a great piece of software, thank you apple! I would like to demonstrate what big difference you achieve by editing the photos. Of course you could just do it right with the camera, but I don’t earn my money with this so it’s ok for me if my photos are not perfect and need a retouch on the mac. First, the original one, then one edited slightly in iPhoto and the last one just played around in Aperture with Heights and Shadows, now I love the result of the last one.


Road Trip to Sighisoara, part 3

Well here is part three of the road trip Saturday was photo day! I have shot several hundred pics. I had a total of almost 800 photos made from friday to sunday, where friday I didn’t take so many and sunday even less, so almost all photos where made on saturday. The first part of the day, coffee, food, sight seeing. I can only repeat, Sighișoara is a GREAT place! I will be going there again, this is sure!   The second part was meeting with the guys from VWforum this was a bit short, but still it was interesting After this, it was once again time for sight seeing and photos. Well here I think is best I will let the pictures talk. the link to the pictures will be at the bottom of this blog. So now to sunday, the next adventure day. After so much bad luck on the way to Sighișoara, could it get worse? Yes it could …. We arrived quite fast to Mediaș and I was already starting to think that we will arrive fast to Timișoara but then I saw Vlady pull over and a black liquid tail behind his car, his oil-sump had a hole after he drove after a big rock. So what could we do? First of all get to a city since in the village where we stopped nobody could really help. I towed Vlady until Sibiu (about 40 km) but since it was Sunday, and the chance that somebody could fix this fast, even if we would find someone, where quite low. So we decided to tow him until Timișoara (about 300km). But with my car being automatic, it was better that Foka took over the towing. A very big THANK YOU at this point! That was really a big help! But please remind me when something like this happens to me that that I will not let myself towed from you, at least not in romania. As wee went towards Lugoj, I couldn’t keep up with Foka and Vlady since I was trying to not hit some road hole again, we took this road since it was 50km shorter. But if you are not towed … take the way over Arad! So I will end here my third and last part of the road trip blog.


Road Trip to Sighisoara, part 1

As some might know, last weekend I and some friends went to Sighisoara to a VW event organized by VWforum.ro but it was not only the fact that there was a VW event that made me drive this far, it was the magic of Sighisoara I noticed on some photos that made me do this little trip. But as life really can suck some time, the weekend was not without problems. So where do I start, lets begin with thursday, my plan was to leave at 15:30 but Razvan was of course late, as we left finally at about 16:00 there was traffic, because of an accident, or rather because of the people stopping to look at the accident (someone please shoot the people doing this). Well the next traffic problem was near Budapest, where the road was under construction so the next delay … Finally at about 00:00 I think we arrived in Timisoara after a beer and some talks about when we will leave on friday I finally got some sleep, not much but … I can sleep when I’m dead
