所谓物理

借用组训。

“大学之道,在明明德,在亲民,在止于至善。知止而后有定,定而后能静,静而后能安,安而后能虑,虑而后能得。物有本末,事有终始,知所先后,则近道矣。古之欲明明德于天下者,先治其国;欲治其国者,先齐其家;欲齐其家者,先修其身;欲修其身者,先正其心;欲正其心者,先诚其意;欲诚其意者,先致其知;致知在格物。物格而后知至,知至而后意诚,意诚而后心正,心正而后身修,身修而后家齐,家齐而后国治,国治而后天下平。”

——《大学》

“所谓致知在格物者,言欲致吾之知,在即物而穷其理也。”

——《补〈大学〉格物致知传》

Firefox settings

1 Errors

1.1 sec_error_reused_issuer_and_serial

I encountered this error after every GoAgent update and finally this solved my problem.

One of the thing I hate about firefox is that when you have internal certificates like those issued by HP Integrated Lights-Out’s (iLO) web page, you have to confirm to download the cert and add it to your cert store. There is no one-click solution to this as yet and neither can I disable this in FireFox even if I only intend to use it in an intranet environment.

More troublesome is when I update the firmware in my iLO and hence a new certificate is generated and when you try to launch the web page for iLO access again you will encounter the following error.

Error code: sec_error_reused_issuer_and_serial

It took me a while to figure it out from googling, and the solution is very simple. Just delete the cert8.db from your FireFox profile, who is usually found in C:\Documents and Settings\\Application Data\Mozilla\Firefox\Profiles\. The easier way is just searching for cert8.db in your computer and delete that file.
