rebuilding a software raid array and stuck with this error? for example, I was rebuilding on a live array and the server took a dive.
try tricking the array into believing its clean, then try to add a new drive or start the array again.
echo "clean" > /sys/block/md0/md/array_state
mdadm /dev/mdN -a /dev/sdXN
or
mdadm --manage /dev/md0 --run
then do a cat /proc/mdstat
raid should be rebuilding!
Dolphin is still missing some features that I have set up in Konqueror.
But EVEN AFTER changing your preferred “file browsing” application to Konqueror under System Settings ->Default Applications, Dolphin still runs on mostly any folder operation. I found that the easiest way to get Konqueror to run instead was to symlink dolphin to konqueror. as root:
cd /usr/bin
mv dolphin dolphinx
ln -s konqueror dolphin
Now Konqueror runs for everything.
instead of doing
ssh customuser@hostname.com -p 12345
put some lines in your ~/.ssh/config file (create it if it doesn’t exist)
Host hostname.com
Port 12345
User customuser
save some keystrokes, now you can do
ssh hostname.com
I managed to pick up a PowerGenix 4-pack of NiZn (Nickel-Zinc) rechargeable batteries and a charger while I was at the International CES in Las Vegas – I saw them demoed at Lunch@Pieros and they were nice enough to donate a pack.
Well, that was back at the beginning of January. I’ve had them in my Wiimote since then, and my battery is still at 100% from a full charge. I thought they were full of bologna, telling me that it was the “next generation” of battery technology, geared towards high-draw use – seriously, how many times have we heard this in the past?
I have a pack of NiCds gathering dust now. They would be on their 37th charge if I was using them in my Wiimote this long.
It seems like we’ve finally seen a STRONG contender towards alkaline AA’s. These batteries even put out 1.6v, a little more than most AA’s, and the same as the best high-capacity lithiums. I really don’t have to mention that it puts the 1.2v of NiCd rechargables to shame.
And another thing, they are cheap.
actually just posting this so I’ll google it in the future and will get to this page. for some reason sound only comes out of the front speakers and is impossible to route to any others. adding this model parameter makes it happen.
/etc/modprobe.d/local.conf
options snd-hda-intel model=6stack
rinse and repeat, I mean, reboot
A man goes in to see his doctor, and after some tests, the doctor says, “I’m sorry, but you have a fatal disease.”
Man: “That’s terrible! How long have I got?”
Doctor: “Ten.”
Man: “Ten? What kind of answer is that? Ten months? Ten years? Ten what?”
The doctor looks at his watch. “Nine.”
one way to make sure that sql injections NEVER happen is to use a prepared statement
perl has been doing it for ages, so by now it should be mainstream, yeah? I wish. but if you’re behind the curve, no worries, here’s how to do it. this is for a simple contact form.
$stmt = $mysqli->stmt_init();
//prepare the statement, use ?'s for where you want to put variables
$stmt->prepare("insert into tbl_contact(contact_fullname,contact_phone,contact_email)
values (?,?,?)");
//bind your variables to the statement, in order. "sss" means string-string-string
$stmt->bind_param("sss", $_POST['fullname'], $_POST['phone'], $_POST['email']);
$stmt->execute();
