I was Vimeo stumbling, happy that I have high speed internet access to watching videos in HD, when I found this.

If you’re too lazy to watch the video, basically what it is is a person once in a while opening their home/office/space to random workers, typically freelancers from the looks of things, in a really casual working session. I guess it’s a lot like a hackspace, but solely for laptop work. I love that there are places like this, and I really wish there were more of them.

I’ve looked through the workatjelly wiki for places in the UK that do these, but it doens’t look like there are any set up at the moment. For the moment I’ll stick with the hackspace stuff.

There’s a meeting on Saturday which I’ve nabbed a ticket for, and am definitely going. I’m just planning on taking my laptop so far, but if I can find the money to, I think I’ll hunt down a Maplins and get a arduino board (which I’m not even sure what it is) and generally geek out. I’m hugely excited if not slightly nervous about meeting a group of strangers.

Turns out some people didn’t know they have access to their H drive from outside of the lab, so lemme explain how.

Your H drive is actually stored on a Linux server, where you have your own user. I doubt that means much to you if you have to be reading this, but it’s cool. It’s basically having your own account on the operating system, and you can do a lot more than just host files on there, but that’s all we’re bothered about at the moment.

You’ll need to download WinSCP. Install that with the Norton Commander view when prompted for it. Open it up when it’s installed, you’ll get this screen. Fill it up with your information!

WinSCP login screen with my DMU information in it

The host name is sftp.cse.dmu.ac.uk, and your username is your P number, with the password you use to log into lab computers. Make sure the file protocol is SFTP.

Then press login, and it’ll take a few seconds to connect. Then you’ll get an window like this:

This is what it looks like when I log in

On the left is the machine that you’re working on now (known as the local machine). They’re all your files and folders on your computer. On the right is your harddrive on DMU’s servers (the remote machine). You can drag and drop files and folders from one computer to the other however you like from then on.

Remember though, don’t delete any of the .whatever files. They’re all configuration files for Linux. To be honest, unless you use PuTTY to access the server command line styles you’ll never be affected by them.

Here’s my RSA public key:

PuTTY-User-Key-File-2: ssh-rsa
Encryption: aes256-cbc
Comment: My first key
Public-Lines: 4
AAAAB3NzaC1yc2EAAAABJQAAAIBv67wL6ms9S2VKS7FzAKzkU7ikhcbA/W8G7mas

nAOVJSr2+YXeJk3OHbcdao83mOKDN/QfV2IsoAYdbEyVtCLRII47tflA/kKDdflH
OfZQbw==

I generated that with puttygen. I use it fine on my server, but I’ve no idea how to use it for anything else. Nor even if I should be.

From there, I’ve really no idea what to do next…

Turns out, ssh-rsa might not be what I want, but I’m going to stick with it. I found an article on public key encryption that looks helpful, but still a bit over my head. I’m tired now though, so I’m going to bed. I’ll look into it again tomorrow.

Just stumbled upon the manual for GPG, which I guess I should be using, maybe? I’ll read it later.

Linux systems get it built into gedit. Pfft.

Hokay! So, that was the wrong key. I’ve made a new one:

Now, I’m working out how to encrypt something.

Huzzah! Done it! So, I have a text file I want to encrypt, textfile.txt which just has “Hi there” in it. Do this to encrypt it, with my own public key:

C:>gpg --armor --encrypt --recipitent shamess@gmail.com textfile.txt

That should output the encrypted text in ASCII to STDOUT, which for my key is:

To decrypt use:

C:>gpg --decrypt

And then just paste the ASCII.

I still have the problems with graphics on both WoW and GW, with no idea what the problem is. I’ve updated drivers and everything. WoW support have told me to do a memory test, which could take hours so I might do it for when I got to bed. A small part of me wants the memory test to find an error, so I can get it fixed. But at the same time, I don’t want Toshiba to take him again…

I’ve actually done a lot of revision today. That makes me even less nervous. I was shocked to see that my first exam is Friday though… it’s a computing resit. I haven’t actually looked at it at all, to be honest… Tomorrow I shall though, and make sure that I understand all the terms in the specification. As all exams, you only need to learn what they want you to learn, even if it’s not relavant.

What else have I done today… Oh, I’ve started reading a C++ book, which my computing teacher lent me. It’s… huge. I got bored at first, where it’s teaching about variable types and stuff, which I already know. I’m reading it though, since I may miss something C++ specific that’ll confuse me later on in the book.

I suppose I’ll go to sleep now. Wake me up at 1100, when the server is back up.

I’m having to adjust to using a mouse again. Once you’ve had the precision of using a tracer pad for a year or so, then you’re given a mouse which doesn’t seem to be able to move in increments of a pixel (it prefers to move in ten pixel chunks), it’s really annoying.

It’s not just that which is annoying. The computer just doesn’t fracking work.

They’ve disabled right click. Who disables right click? I managed to get at my flash drive, and it’s installed start.exe, which I’m sure is a lovely programme. And I can’t install the 2007 patch for Word, so I can do zero work.

Oh right, I could convert it online. But I wouldn’t be able to download the converted file. Joy.

(I’ll fix this post when I get to a computer that works.)

I expect that that web page in newer browsers would just break, or it’d be outraged and refuse to show the page. The other HTML questions are awful too. I only got a few marks in one question because I used <p style=”text-align:center;”>, rather than <center>. The thing is, depending on how well the person marking my exam knew HTML, I would have gotten full marks for that bit.

Okay, I guess I was intentionally using CSS because I knew they were looking for <center>, but still, my point’s still valid. AQA shouldn’t be teaching us invalid code.

May

In May, I should be (at least, I think I am) retaking computing, unit 2 (CPT2) and law, unit 2 (LAW2). Both of these are AS resits because I failed them last year, which is always fun.

June

A2 exams I’m taking in June are law, unit 6 (LAW6) and unit 4 (LAW4), computing, units 4 (CPT4) and 5 (CPT5), and business studies, unit 11 (BUS11).

I’m resitting law, unit 5 (LAW5).

Jolly good, only seven eight exams. Plus three sets of coursework. Before July. Joy.
