I run into an investment advice book printed in 2002 (i.e. before the recession) and the preface starts like this: “(The US people should be) positive about buying or refinancing a home at historically low interest rates or buying a new car under new no-interest offers”. Obviously the recession came later on and everyone who invested in homes (and cars) lost a good deal of money.Moreover, many articles about the recession and its effect on the housing market mentioned that when interest rates are so low, there’s one way to…UP.
So..I was wondering whether I should spend my valuable time to read the rest 280 pages … I guess not… 🙂
Zenbe Lists has been down for the past few days and I am losing track of my things todo. Had a huge list of things to do on my days off, but… Anybody got any suggestions for a TODO lists program that works with iOS 3.0.1 and will sync with a PC? Guess I could always try a pen and a piece of paper, but I am afraid it will take me some time to remember how to use this archaic user interface.
I have a Windows XP installation on a VMWare hard disk. Today I tried to boot it, but… OOPS (no.. I don’t mean Object Oriented Programming and Systems… I mean..crap!). It seems I forgot the password of the installation. So a little adventure started…
1. After a bit of research I found out that there is ophcrack. I downloaded the live CD as an ISO image and set VMWare to load that CD.
2. When VMWare starts and before windows starts booting I clicked on the VMWare screen and pressed ESC. This gives me the menu to select the device I want to use to boot.
3. I chose to boot from the CD.
4. The ophcrack live CD starts loading, but when it finishes I get a: “No partition containing hashes found” error.
5. The problem seems to be that the Windows installation is on a SCSI virtual disk that is not recognised by this distribution of linux. Tried “fdisk -l” on a terminal from within the ophcrack live CD and it didn’t return any results. To be able to crack the password I need to have access to the “WIndows/System32/config/ folder of my virtual hard disk. So…
6. I created a second virtual hard disk in the same VMWare virtual machine. I downloaded an ISO image of Ubuntu
7. Installed Ubuntu on the newly created hard disk.
8. Boot using Ubuntu. Ubuntu was able to access the virtual hard disk of the windows installation. I copied the folder “WIndows/System32/config/” on my local Windows 7 installation.
9. Downloaded ophcrack for Windows and installed it on my Windows 7. Also downloaded the XP Free Small Table.
10. Launched ophcrack and clicked on “Tables”->Install and selected the folder where I had downloaded the XP Free Small Table file (if it is a zip file you need to unzip it).
11. Select Load->Encypted SAM and select the “config” folder I had copied from the VMWare installation (through Ubuntu).
I keep this blog (which I don’t update very often, but that’s another story) and I post both personal and professional (in the sense that it will appreciated by Computer Scientists) content. I would like to import all blog posts automatically from this blog into my facebook and linkedin profiles.
The thing is that I don’t want to post Computer Science related content into facebook and I don’t want to post into my (professional) linkedin profile all kinds of rubbish. I found out that it is easy to selectively syndicate content depending on the tags that I will add to my post.
So I added two tags, an import_facebook for posts that I want to be imported into my facebook profile and an import_linkedin tag for posts that I want to be imported into my linedin profile.
Then I installed the “WordPress” application for linkedin and I set as a feed url of my blog the following: http://kyriakos.anastasakis.net/tag/import_linkedin
I also installed RSS Graffiti for facebook and I set as a url of my feed the following: http://kyriakos.anastasakis.net/tag/import_facebook/feed
From now on any WordPress post I tag as “import_facebook” will be imported into my facebook profile, while every WordPress post I tag as “import_linkedin” will be imported into my linkedin profile. Before installing the WordPress and the RSS Grafiti apps on your linkedin and facebook profiled respectively, you need to have at least one post tagged “import_facebook” and a post tagged as “import_linkedin” for the applications to pick up the links properly.
I use a virtualbox virtual machine to run Ubuntu from within Windows (yes, I know I am a masochist). Anyway, every time I resume the virtual machine Ubuntu loses connection with the internet and I have to reset the interface. In windows from the command prompt you have to do an ipconfig /release and an ipconfig /renew. Similarly in Ubuntu all I had to do was the following:
1. sudo ifconfig to get a list of all the network interfaces. There you can see the name of the networking interface that you need to reset. In my case I wanted to reset interface “eth3”. So I did: 2.sudo dhclient -r eth3 to ipconfig /release 3.sudo dhclient eht3 to ipconfig /renew
That’s it! Got a new IP and I can access the internet!
This morning I came out of the shower and found my iPhone on the floor. I had forgotten the alarm on and since it’s on vibration, the alarm was ringing for quite some time until the phone fell on the floor. I picked it up and the home button wasn’t functioning, the speakers were dead and it wouldn’t charge. The phone has been like that for the whole day.
I just came back from work and I decided to use a novel approach based on strict scientific/engineering reasoning. I let it fall down again. I picked it up and it didn’t recognise the Sim card. Ooops… I switched it off, removed and re-inserted the Sim card and turned it on. It’s back to normal! The home button works, the speakers are loud and clear and it charging at this very moment!
We had a storm a few months ago and before the storm a number of lightnings struck the area close to where I live. I recorder a video of the lightnings and I noticed something weird…
The first image shows the view from our house. The second and third images show two lightnings. The third image is quite interesting, because the closest building on that image is around 20 meters away from where I was standing; and the lightning trajectory appears all the way to the bottom of the picture. It’s been ages since I last studied physics, so even if I knew how to explain how this happened, I have now forgotten! My thoughts so far:
either the lightning struck less than 20 meters away from where I was. It doesn’t seem likely, because I assume I would have felt it striking so close. Moreover the clouds where the lightning started its trip [sic] appear to be far away close to the mountains.
or the camera was able to capture the trajectory of the lightning behind the trees and buildings!
Update: The method described in the following proved to be useless in the summer, when the laptop became too slow (almost unresponsive). I guess setting the CPU Fan Control level to quiet does not work well when the environment temperature is relatively high. So, I removed the fan cover (all you need to do is remove 6 screws on my laptop) and injected some sewing machine oil on the fan! Now the laptop is TOTALLY silent again! Hurrah!
The noise level of the CPU Fan of my Sony Vaio VGN-SZ71E laptop was driving me crazy for the past few days. When the laptop was on, you could hear the fan operating even in the room next door. The fan was also producing vibrations, which I could feel when I had my arms on the keyboard palmrest! It’s needless to say you can’t work properly (i.e. concentrate on your work) under these circumstances.
I tried removing the chassis to see if I can replace the fan, but in order to have access to the CPU fan on this laptop model you need to disassemble pretty much everything! Luckily there is a workaround.
I had installed the Sony VAIO Power Management utilities, which allow me to manage the CPU Fan speed (Control Panel -> Power Options->VAIO Power Managent -> CPU Fan Control ). I set it to level “1-quiet” and I have to say it is much better now. Probably this has some impact on the performance, but this comes second to the peace of mind when working 🙂
My first experiences (I’ve only been playing with it for 10 minutes):
1) Doesn’t import my huge firefox visited sites history. If during the installation I ask it to import the history it just doesn’t proceed, without any error. The third time I tried to import my firefox settings I unticked the “import history” and it worked.
