Even if I have already downloaded and installed the webviewer plugin update, I was continously redirected to this webpage which is confusing. I have tried to google it but I cannot find any solution regarding this issue. But not until I realize that many korean companies love Internet Explorer so much.

Evernote Dark Theme Alternative

I use Evernote for PC in my daily note-taking activity. However, It hurts my eyes to look at its window due to the bright light intensity.

Since there is no official dark theme from Evernote, here is my workaround solution for those who need to use it in a “dark” theme.

Embedding Image From Flickr

Recently, I am trying to embed an image from my flickr account to one of my post. When i go to my flickr account and open one of my picture page, I can’t discover the exact link of my image. Then, using helper tool (firebug) I try to trace the element of my picture page. And taadaa… Finally, I can find it. Thanks firebug!

Actually, the url-format for embedding flicker image is as follow:

https://www.flickr.com/photos/user-id/picture-id

Just like the above image, my flickr user-id is 65150829@N02 and the picture id is 8053758291. Thus the complete url is as follow: https://www.flickr.com/photos/65150829@N02/8053758291

We can check our flickr-id using the following website: http://idgettr.com/

ORA-00204 : error in reading (block N, # blocks M) of control file

Yesterday, After severe errors had happened in My Computer. I couldn’t start my database instance and got this following error.

ERROR MESSAGE:

ORA-27070: async read/write failed
OSD-04006: ReadFile() failure, unable to read from file
O/S-Error: (OS 23) Data error (cyclic redundancy check).

By checking the error stack that showed an O/S Error at the bottom line, I decided to use “Check Disk” Tool on Drive E:\ (where my oracle data was installed) to fix this error. Fortunately, by the time the process finished, I was able to start my database instance & not getting such error anymore. Lucky Me 😀

Note: Please remember, If you run the check disk tool your drive will be temporary unavailable.
