Connect your kindle to a power source and charge it until this screen disappears. This may take up to 30 Minutes
If you continue to see this screen after charging, you will need to reset your Kindle. Unplug it from the power source, then slide and hold the power switch for 15 seconds.
In short, both did not work, Once plugged into a charger, The orange light will come up for a few seconds, then it will disappear, my charger LED will also turn off meaning no power is being drawn, resetting did not resolve it either as it seems there is absolutely no power in the battery, considering that i have left it for months without use or charging.
So, the solution seemed to be heating it up a bit against an electric fan heater (Few seconds, don’t make the kindle hot), then plugging it into a charger kept the orange light on, the orange light flickered for a few seconds after plugging it in (Obviously not a “by deign” kind of flickering).
Also worth mentioning that one of the chargers works better than the other, after the heating, one of the chargers (Larger capacity) seems to hold the orange charging light steady, while the smaller one seems to fail within a few seconds of plugging it in (orange light goes out)
Now, it seems to be charging, the battery empty page refreshed, but still gave a battery empty page, then a few seconds later, what do you know, that battery empty screen disappeared and the kindle initiated a boot sequence (The normal screen that appears when you start the kindle with a progress bar) (If this does not happen after 30 minutes of orange light lit up, You might want to consider resetting it like the kindle says).
This is one of the very old kindles, It dates back to many years ago. In the footer of the menu, it says kindle 3.3, on the back it says (Kindle model number D00901), But i am not really planning to invest time finding out what this kindle is called, it is the one with the keyboard
Source of the problem, a theory, Lithium batteries have a cutoff charge, meaning, devices leave some power in a battery (And consider it empty, switching themselves off before a complete drain) because if the voltage goes below that threshold, it can be dangerous to recharge.
Heating probably registered some voltage on the battery convincing the kindle to charge it.
The 3-4 seconds of mild flickering is still a mystery though.
Final note: Once the kindle booted, both chargers seemed to work just fine.
First thing first, using the manual, your commands will go in dry run mode, no hints are given on why needed changes are counted but not executed, this is because you have to rn the command with the y switch to do the changes, here are a few ones you will use often
dbmail-util -dy – set delete status on deleted mail (deleted by IMAP or POP)
dbmail-util -py – delete messages with delete status
dbmail-util -by – rebuild the caches
Without the Y, no changes will be made to the database
My always on Linux machine is a dell FX 160, very low power consumption, should work as my VPN, asterisk server, and wake up other computers when i need them, the device itself is multi homed, So i basically need it to wake up other devices on one of the networks
The commands you need for this to work are as follows
etherwake -i eth1 xx:xx:D2:B2:30:C9 (My laptop)
eth1 is the network connected to my mini linux server that is connected to the target network.
Thats all there is to it, in addition to enabeling wake on lan in your BIOS
Although the copy program cp in Linux overwrites without prompting, in practice, it does not, the reason behind that is that the command is aliased with the (cp -i), you can check that by using the alias command
So there are 2 solutions to this to make cp overwrite
The first would be to unalias, while the second would be to execute the command directly with
\cp
Or you can use the full path to the alias command like
I have been using DD for a long time, specify the block size etc, then pipe it into PV if you like, and there you have it
But you can use PV directly
So let us assume we want to put sda on sdb (See how direction arrows are pointing out of sda in the command)
pv < /dev/sda > /dev/sdb
and you are done, no need for DD, PV is faster because it checks the speed on both disks first, and there you have it
At first it will be much faster than you anticipated, that is because it is buffering in RAM, once you run out of ram, the speed will drop back, even if you dont run out of ram, there will be time for the sync operation
For example, while cloning my 40GB SSD onto an 80GB western digital, at first the speed was 180MB/s, once i ran out of ram, it dropped to 50MB/s
There are 2 popular packages to deal with duplicate files on linux
The first would be fslint (apt-get install fslint), the down side is that it is not sorting by file size, because when i have 10,000 duplicate files on my disks, i really don’t want to deal with them all and make choices, so what comes to mind is this, the second is fdupes, i have never used it before so i would not know, so we will be using fslint with a small script.
first, find the duplicate files, in my case, i only want the ones over 2MBs
Now, this little simple script should read the data into a mysql table (Command line PHP script, you will need to edit the mysql username, password and database), you also need to tell it what the path you used in the command above is (I used
“/hds”), also included is the database sql file, you can put that in with PHPMyAdmin
Now, you can run the above script and it will go and investigate file sizes on the file system.
Then, you can either walk through the database after sorting by size, or write your own display script (Fetch and print, nothing too fancy), so you will know where your greatest gains are, and this way you will not lose a day filtering those duplicate files.
Just because this took a lot of research from me (Looking at specs), I am posting this here for my own reference.
Note: CF cards will work on both 3.3V and 5V. so there is a bit of a mystery on why we need a voltage step down chip and a jumper for this particular adapter, other drives are clearly incompatible IDE interfaces.
it turns out that when combined with a converter using the fc1307a chip to create CF out of 2 SD cards, it will not work without a voltage step down, with the wrong setting, or with cards with no step down, a computer will see the combined cards, but will fail when trying to format them for some reason.
The 1.8″ adapter (Sideways IDE interface) is 3.3V, the normal 2.5″ disks are 5 Volt, the adapter we have that turns CF cards into 1.8″ or 2.5″ compatible drive, has a JUMPER to select, this jumper effectivly activates or deactivates the voltage step down chip (The only chip on the board)
So there you have it, 1.8″ and 2.5″ PATA drives are not compatible regardless of the fact that the PIN interfaces are the same. the adapters with a voltage step down will work on both, but you need to set them up first with a JUMPER
APC is gone, no longer maintained, now there are alternatives.
For opcode cache, PHP 5.5 (5.6 shipps with jessie) the opcode cacher ( OPcache ) module is installed and enabled by default, as for key cache (Persistent across pages), we have an alternative called APCu (Just the user key value cache), once installed, the apc_ functions return to PHP so it is a drop in replacement, no no program modifications needed.
To install APCu, you run the following
1- Install the tools
apt-get install apache2-threaded-dev php5-dev php-pear make
2- Before you get APCu-4.0.7, you should check what the latest version is !
pecl install channel://pecl.php.net/APCu-4.0.7
Now you are done, all you need to do is add
extension=apcu.so
to the php config file, in my case, what i do on debian jessie is add it in a file here
/etc/php5/apache2/conf.d/apcu.ini
There you have it, you are back on track.
