eBay-auction end-time affects profit

Scientists from my hometown’s university have found out that eBay-auctions, which end during the day achieve higher profits compared to auctions ending in the evening. Popular belief is that evening-endings are more profitable since more surfers are online. However one needs to take into account that the number of auctions ending after 6pm is significantly higher due to the same reason. During daytime, there is a shortage of auction-endings and therefore higher bids might be achieved.
Of course this will only work as long as this does not lead to a paradigm shift with more sellers shifting to during-the-day acution endings. The results might be interesting though for (pseudo-)commercial Powersellers offering larger volumes. They can both test the theory and shift a partion of their stock to end-time-endings and another portion to evening-time-endings.

Google PageRank algorithm uncovered

Philip has managed to reverse-engineer the Google PageRank algorithm and confirmed the fears of all professional webmasters.

Though this is satire of course, the interesting point is that there has to be such a piece of code, and that it most likely will look rather similar to the one Philip made up. It would be really interesting to have a look at it.

Have fun with wardrivers

Via Gadgetopia: Peter Stevens found out that his neighbours used his wireless network without his permission. Though he should have properly secured it in the first place, he implemented some funny ways to annoy the bandwidth thieves.

Agnitas E-Mail Marketing system as Open Source

Surprisingly offline media can still deliver genuine news to me. The recent issue of Internet World Business contained an article that the renowned German E-Mail Marketing specialist Agnitas has releas their email- and dialog-marketing software package as Open Source (see press release) .

Since 1999 Agnitas is among the leading companies worldwide to provide email marketing services and solutions. Agnitas CEO Martin Aschoff is a highly valued expert on all aspects of email marketing. He is panelist on many conferences and gets quite a lot of press coverage. I was able to see the Agnitas software on many shows. In a market which is under massive scrutiny and has a public perception of being slightly “shady”, Agnitas is clearly among the “good guys” of that industry, taking an active part in the legislative process and working with ISP’s and anti-spam activist on whitelisting projects and spam avoidance mechanisms.

Due to the pretty high price ticket on their services I never used them for my company. So I am pretty thrilled that I can now use their system as Open Source. From their point it is clearly a smart move: they probably get quite a lot of marketshare. Competition might very well get drained to a certain extent. And they will most likely have some users of the open source software move to a premium service sooner or later. Of course there is also the danger that they will cannibalize their charged services a bit.

Nevertheless I am looking forward to install the software soon. The product is called OpenEMM (Open E-Mail Marekting Manager), runs on any LAMP-system and can be found at OpenEMM.org.

WordPress users – check your settings!

If you are running WordPress as your blogging platform and if you have been trusting enough to leave User registration enabled for guests, DISABLE IT IMMEDIATELY (in wp-admin >> options: make sure “Anyone can register” is not checked).

Thanks Jona.

New advertising strategy for technozid.de

I have been recently accused of pulling off a publicity stunt regarding my Bodenständig 2000 iTunes blog entry. I don’t know wether the bands record sales skyrocketed afterwards – my AdSense income for sure hasn’t. When the story broke I got well over 6000 unique hits – and not a single AdSense click!
This blog has not been started to make me rich (though I wouldn’t object). However I have a few expenses to cover and it would be nice if it could pay for itself. So I changed the advertising strategy for :tz: – no more annoying ads inside the articles. From now on, there’s only 2 ads on the frontpage: one AdSense ad below the first post and an Amazon ad below the second post. On the comments pages there is another AdSense linkblock. That’s it! Hope this is a good compromise between refinancing the blog and not being too annoying with ads.

Any feedback will be appreciated!

New Joomla vulnerabilities

Will they ever get it right? Again there is a new vulnerability targeting Joomla (the CMS formerly known as Mambo) sites. Don’t these guys learn? Mambo/Joomla has a whole track record of vulnerabilities, and the story of the split-up doesn’t sound reassuring too – yet its becoming more and more popular even among professional webmasters! Admittedly, the learning curve is much smoother compared to Typo3 – but for Typo3 we only had one security issue so far and it was dealt with within a day. There’s no such thing as a free lunch – and if you want it easy and shiny, something has to give. In Joomlas case it seems that security is the tradeoff. Go figure.

GuitarFX hijacks your browser

I’m on vacation right now. So I began my long planned task of improving my guitar skills with dusting off my electric guitar and putting on new strings. I have not yet cleaned & repaired my amp so I plugged the guitar into the PC and abused it as a makeshift amplifier. This worked surprisingly well, and before long I discovered a few guitar-centric websites where I found dedicated amplifier and DSP-effect software. The most promising one was GuitarFX, and with it my PC worked as a better amplifier (in terms of available effects) than my real hardware amp & effects ever worked. For those of you who dare, here is a first example :-)

That was mostly on Saturday. Since I recommended a few links to BoingBoing during the weekend, I checked the site a few times. Already then I had a rather odd feeling, which was confirmed today: both BoingBoing and Lifehacker show a statistically above-average amount of guitar-, guitar-amplifier and guitar-effect related ads:

I was pretty surprised to see such targeted ads. Actually I never saw targeted ads to such an extent before. But only after similar ads showed up on Yahoo as well I started to realize that someone has hijacked my browser. So I ran virus and spyware checkers – but they didn’t find anything special. I did a thorough run around the Windows startup options only to find nothing. So I had a closer look at the ads and finally clicked the “Remove these ads” button. This transferred me to a site which said:

Annoying ads in your internet browser? Don’t scream like a baby! You have ads in your TV, but you don’t panic even you can’t remove ads from your TV.

The site showed a few links – one redirects to a Google sponsored Firefox download promising FF does remove ALL banners, and another one to payable (sic!) banner removing software. OK, so where has this bugger embedded itself into my system? The ads are showing up in Firefox and Internet Explorer, so it must be pretty low level. One link dubbed “recommendations for stupid beginners” had something interesting to say:

Special notes for GuitarFX users: you must uninstall this software via Windows Control Panel. Sometime you must install it and then uninstall immediatly, this helps in 100%. Note: you was informed about ads in the licence.txt file of GuitarFX, if you run it, you agree to see ads. Uninstall it via Windows Control Panel and do not see ads.

A-ha! So it was GuitarFX! Unfortunetaly the mentioned licencse.txt file wasn’t there, but there was a readme.txt and it said:

The Demo version can change your default home page in Internet Explorer and can show banners or other ads and can visit some www pages that can content banners, other ads and standard internet counters wich can track info available via internet and internet explorer you use and, may be, some other tech info about GuitarFX itself and your PC hardware and software. [...] Use of this software indicates you agree to this.

My IE hompage is protected so this one could not have been changed. So I dug a bit deeper in the installed software and finally
found a small batch-file which had the timestamp of the installation of GuitarFX and which was manipulating my hosts-file:

copy C:\WINDOWS\system32\drivers\etc\hosts.001 C:\WINDOWS\system32\drivers\etc\hosts
copy C:\WINDOWS\system32\drivers\etc\hostsb C:\WINDOWS\system32\drivers\etc\hosts

That was the culprit! I thought my hosts file was write protected – but maybe the software did clear that too. I gave Spybot S&D a run at it, filled it with its default entries and write protected it again – and now the ads are not showing anymore.

I’m pretty disappointed about this behaviour. The program looked good and was very versatile – I was even considering to buy the full version. But implanting spyware on my system is so out of bounds! I should have been warned though. The creaters of GuitarFX made such a pathetic approach at search engine spamming, distributing their program across various domains and Geocities accounts. It made me smile inwardly. But they caught me. They did. And that’s the part that really surprised me since I consider myself a Pro at spotting shady methods like that.

So, beware of GuitarFX (.net, .org, .info) – unless you want to get your browsers hijacked! Gladley there are alternatives who are playing fair. I’m currently evaluating Guitar FX Box and it looks good.

I've seen my first Google Box today

Today was the last day of Jona’s internship at my company. In order to make that last day a bit special we made a field-trip to our ISP. Their building is rather unspectacular and I think I saw a little disappointment on Jona’s face upon entering the slightly worn-out apartment-like building residing in a backyard off the main road. He brightened up a bit when our guide showed us the bunch of bundles of fibre cables – each several inches in thickness – entering the premises. Any doubt that this ISP is indeed a “real” ISP vanished when we entered the inner sanctum – the server hosting room. Multiple rows of 19″ racks – each equipped with an UPS and stuffed with server boxes and switches – produced together with the A/C a deafening noise.
Google MiniOnly thanks to our decade-long business relationship we were allowed into this room, and we were specifically reminded not to look too closely at the owners name tags attached to the servers, and if we did, to forget them immediately. Two huge racks consisted solely of the servers of a well known TV station (that much I was allowed to disclose), and one had as the topmost device the azure blue Google Mini. It looked surprisingly normal. As a matter of fact it looked pretty much like our firewall, only in blue. Nevertheless I was quite surprised to actually see one “in the wild”. I wonder how many of those devices are out there. Anybody using one willing to give a report on how it works?

"Your cockie is OK" – A severe case of "Lost in translation"

I was browsing some Japanese sites with the help of the Google translation tool, when this rather reassuring message appeared on screen. I don’t like the way they belittle it, but otherwise they are right with the statement. I’m only wondering how they found out…
