Google talk stopped working, make it work again

Google talk stopped working today, but i am so used to it, i don’t think i can live without it.

When i try to login, it says, username and password do not match, (You provided somename).

So here is the plan to make google talk work again.


The google talk installer is all over the internet, google talk uses XMPP as a protocol

I will be creating a server, and creating a file to make google talk connect to my server

Now i will tell all my friends to register their existing email address with this server and to run the file that changes the server for google talk, and we should be back online again

I will be monitoring my own instance of google talk for incoming and outgoing data so that i can modify the server so that it would become fully compatible since google talk is not 100% XMPP.

I will keep everyone posted on this. Hopefully i will have it working by the end of the day

lead acid batteries – all about

Because i use lead acid batteries on my UPS systems, i will be putting all the relevant information that i need on lead acid batteries here

1- What does 74ah (74 amp per hour mean)
In most cases, it means 3.7ah over 20 hours, so you can draw 3.7 amps for 20 hours before the voltage drops to 10.5V, the equation is not linear, so basically you will be able to draw less than 7.4ah in 10 hours (Less than double for half the time), the rating is usually 20 hours on most batteries, the Bosch car batteries (S3 S4 S5…) are measured for 20 hours for example.

The CCA are usually measured for a 10 second period until the voltage drops to 7.5V (Yes, minimum of 7.5V not 10.5)

Now, sometimes, i connect an inverter and a power supply and a battery together, so that the inverter draws from the power supply, while the battery is technically maintaining its charge, if you can’t control the current, and just want the charge to stay put, something between 12.6 and 12.7 is a good voltage, but to be on the safe side, fully charge your battery, then let it sit for 24 hours, then get a voltage reading, tune your power supply to that voltage, and connect them all together.

Firefox not caching

After spending the day trying to figure out why firefox was not caching images from my website even though chrome seems to honor the caching headers from the server correctly, it turned out that my browser settings were not correct

Somehow, caching was disabled in firefox, to enable it i did the following

visit about:config (fill it into your address bar), this will give you your browser settings

in the top box, type in browser.cache

Make sure both browser.cache.memory.enable and browser.cache.disk.enable are set to true, if they are not, you simply double click it to flip it.

Close this window and try (no need to restart firefox).
