Marcaria is temporarily down

Marcaria, a domain name registration service provider, that I just used to register my new .at domain fastbooks.at, is down. I have registered this domain name yesterday to create a book shop for German speaking customers. I received the e-mail that the domain is registered, but as I wanted to chanhe the name servers to point to my provider, the site didn’t respond. At the time of writing this the site seems to be down at least for an hour now.

I chose this company because of good prices and good customer support, but I hope this downtime is an exceptional exception and not a common day at work.

‘File is corrupt’ error while installing Firefox

Today I have tried to install a new version of Firefox to my girlfriends Asus EEE that I already wrote about. I downloaded the latest version FF 3.6.6 setup file from Mozilla site and tried to run it on Windows 7. I was surprised when I got the error message while extracting files that the ‘file is corrupt’. I couldn’t continue, so I tried several things that didn’t help at all: re-downloaded the file, downloaded the file from Chrome, downloaded the preview version of FF40b2pre, downloaded the file from Snapfiles… After that I decided that this is weird and have downloaded the file to my Win XP machine, put it on my USB key and carried it to the EEE. The file was still corrupt to my surprise (that ment that Windows 7 are not weird), so I started an investigation of my own.

I downloaded the file several times from the same source. The file size was the same, but comparing the files by content revealed some differences.  How could this be possible? I have restarted my Netgear router, restarted my cable modem, tried to connect directly to the modem but this didn’t help. I have read several forums – many people have had the same problem but there seemed to be no solutions. All the suggestions were directed in the anti virus software, but since I don’t believe in that and don’t use it this couldn’t be the case. I have read the forums further and have discovered…

…SPI or stateful packet inspection that my Netgear router WGR614v6 does. I have read a few things about it  and it seemed ok to turn it off.

I have restarted the router and tried downloading the files again. This time they were identical! I am using this router for several years now and this was the first time this has happened. I’m not sure why, or what caused it now, but I’d sure like to know more about it.

The ‘file is corrupt’ error while installing Firefox is now gone, so I can continue on my tasks and thank the web again for helping me solve my (or computer’s) problems.

Battery time research on my Samsung Galaxy i7500

Since I’m deeply disappointed in battery time of my Samsung Galaxy i7500 smart phone I have decided to measure and compare the results of my phone’s battery life with other owners of this same model. I have fixed the first battery issue I had so these results are measured without using the original pouch.

My methodology of measuring battery life is simple. Every time before I start charging the phone I save two values: the time phone ran since last charge in hours and the current level of battery left in percent. Both values are reported by the phone itself and are not measured by me. The other rule I have is that if the battery level is higher than 50% at the evening when I go to sleep I won’t charge the phone. If the battery level is bellow 50%, I will end the measurement and charge the phone.

The phone is turned on all the time, including during the night. Data synchronization is always turned on, I use only 2G networks, Wi-fi is turned off, GPS is turned off and Bluetooth is turned off. I use my phone for calls, messaging, reading e-mail and some browsing. Most of the time I’m in the area where the signal strength is strong (all bars).

I have been doing my research for two weeks now and here are the first results:

Time without charging Battery level after time without charging
62h 16%
78h 0%
72h 18%
64h 38%
38h 36%
52h 13%, then after a call jumped to 33%; after a few minutes jumped to 22%; then back to 13% soon; finally: 53h, 0%
62h 3%

As you can see from the table the results are pretty low. The longest battery time I got was 78 hours after which the phone was dead. In working days this means that the phone worked for 3 days and then let me down on the fourth day. The average battery time I got out of my Samsung Galaxy i7500 in these two weeks was 61 hours, which is 2 and a half days. The result is pretty realistic – sometimes I have to charge my phone after two days and sometimes after three days – sometimes it lets me down in the middle of the day.

Compared to 422 hours of standby by time or 8,2 hours of calling time specified by the seller my results are pretty lame. Compared to other users of this phone my results are a little above average.
