Installing MongoDB on CentOS 6
I would have written a guide on how I did this, but the blog post over on If Not True Then False covers it perfectly, so just go over there and follow their guide.

Home sweet home

Having decided it had been far too long since we last had a house warming, there was really only one thing we could do to fix this – move. So this is our new place. Actually, it isn’t, but ours is almost identical to this one, but with nicer carpets and air conditioning.
If you’re wondering why the photos are rubbish quality, it’s because they were compressed into GIF accidentally and then re-compressed to JPEG. I could redo them, but I have more important things to do.

Saving files in memory
If you need super quick access to a file, for example a log file which isn’t going to be too big but it being used by a script which is time critical, then rather than writing it to disk, you can mount part of your file system in memory and write to it there.
This has the disadvantage that when you restart your system, you will lose the data. But for test scripts, logs or other temporary files that you don’t mind getting lost, it can really speed up performance.
Luckily, most systems come with a an area mounted in memory already – so you don’t even need to configure it!
cd /dev/shm
If said directory exists, you’ll have a memory mounted directory already and can start using it immediately.

Editing your hosts file
If you want to put custom entries in your computer’s DNS (for running addresses for a local server for example) you need to edit your system’s hosts file. On Unix systems this can be found at:
/etc/hosts
On Windows systems, you need to go to:
C:\Windows\system32\drivers\etc\hosts
To add a custom entry, first enter the IP address (if you’re running a local server you’ll want to set this as 127.0.0.1), then put a tab and then the host name.

Lloyds TSB headaches
Wednesday, February 8th, 2012 | Life
Recently, I received a letter from Lloyds TSB saying they had begun charging the charity a fee for its bank account. This seemed strange given we had a fee-free small charity account. So I phoned them up to find out what was going on.
Turns out, they hadn’t actually set it up as a charity account but had instead set it up as a regular business account. This meant they needed to transfer the account to a whole different area of the bank – something which is apparently quite complicated as when I phoned back to check two weeks later, the action which I was told I didn’t need to check up on because it would just be done, had not been done.
I gave it another few weeks and then I decided to log into my internet banking to see if I could see if it had been fixed. This is no small task because Lloyds TSB require you to use a card authentication system. But, because they don’t give debit cards out to small charities, they have to send you a special card, which isn’t a debit card, but which can be used in the card carder.
The card reader is massive btw, it’s not the kind of thing you can keep on your keyring, like you potentially could with the HSBC one, if you had seriously big pockets anyway, it’s not like theirs is tiny either.
So I arrived at the Lloyds TSB website and selected logon to business banking. First, I had to enter my user ID. This wasn’t easy because my user ID isn’t a memorable username as you would expect – it’s a string of nine random digits.
Luckily, they send you out a card to remember this. Though it isn’t a card with it printed on, it’s just a piece of cardboard with a white box that you can write it in yourself and hope that it doesn’t get rubbed off on the gloss finish.
I finally found my card and punched in my user ID. Step one was complete! Next I had to input the security code generated from the machine. So I dropped my authentication card into the authentication machine and typed in my PIN. It rejected it.
I tried again. It rejected it again.
So I clicked on the “I am having trouble logging in” link and it began asking me more questions about myself, for security purposes of courses. After four times of it telling me I didn’t exist, it finally let me through – only to tell me the only thing I could do was to phone the call centre.
I did phone the call centre and the nice woman at the other end of the phone said that she would have to get a new PIN sent out to me, and this would take a week to arrive (they can’t give it out over the phone to allow me to access my account now or anything). so I asked her to do that.
Next question, she needed two of the digits from my telephone banking password. I gave her those digits. She said they were incorrect. So now I can’t use telephone banking either apparently.
We eventually managed to bumble through, involving a shot in the dark guess about the year that I set up the account and a new PIN has now been dispatched to me in the post. As soon as I get that, I will be able to log into the account to check if they have changed it to the correct account type yet and refund the erroneous charge they put on the account. Wonderful.

Using TextEdit as a text editor
One utility Mac OS X seems to be lacking is a simple text editor such as Notepad for Windows. It comes with TextEdit but the problem is that this uses rich text format (RTF) which is very annoying when editing system files or code.
Thankfully, you can reconfigure it to use plain text.
Simply go to TextEdit on the menu bar and hit Preferences. The top option should allow you to toggle between Plain Text and Rich Text.

We were discussing earlier in the day how the idea of the alternative scene is that everyone is alternative – yet everyone dresses the same. I’m not sure I quite surprise to this – Alternative is more like a movement, like Postmodernism. But in any case, I decided it was time to embrace such ideas, and so I shunned the regular black outfits in favour of my bright red American Football jersey.
It was also great to see Mike from Bristol put in a guest appearance, as well as Norm and Maths Chris get their disco on, and we even finished the night with a very retro trip to Pizza Milano’s. Good times.

Get the system time from the terminal
Wondering what your system date/time is? Easy!
date
It’s that obvious ;). Don’t mistake it with the command “time”, which won’t return you what you want.
