Geeking it up together

After working on Summer09 all day (that’s its working title), I’ve decided to take a break now that the hours can now be called “small”.

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

What is Jelly? from Amit Gupta on Vimeo.

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.

Access your uni drive from anywhere

This is mostly for DMU students, but this might actually turn into a WinSCP tutorial.

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.

I'd RTFM if I could find it

Tonight’s adventure is going to be understanding how to encrypt stuff using my public key, and then how to unencrypt it.

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
OLT50qFCyPdoh1hlK18Vg/3okbhVybqQmXFKT6jH6+gzRc6yZvUw7rqjAk+j8BMR
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:

And then just paste the ASCII.

Fair use is totally an excuse to break the law

You may notice that I’m putting a load of course stuff online. This may take a while. I should have done this back within the first week and just kept up with it, but I guess I didn’t and now I’m paying for it.

On the other hand though, it kinda means that every scrap of information that has been taught to us within DMU will be put online… I feel like I’m divuldging trade secrets which may well be illegal… I mean, why go to DMU – or university at all – if you can just come here and look at the material, right? So I’m going to avoid posting actual links to presentations and stuff, and just summerise it in my own words, which I’m fairly sure doesn’t evoke any copyright stuff.

And if it does, I’ll plee educational use, which is covered under fair use. S’all good.

I didn’t know that my systems analysis stuff had to be submitted on- as well as offline. I’m hoping she’ll still accept and mark it without me getting in trouble with due dates and stuff. To be fair, I submitted it by hand weeks before it had to be, that must count for something. She’s knows I did the work on time.

I got 1% chance of plagorism though, which is awesome. Most people get around 30%, apparently. I’ve always prided myself on having my own writing style – even if it is too informal sometimes. When people assume that I’ll steal someone elses work I’m kinda offended because… well, I’m the only person that can ever write like me.

Anyway, computer technology lecture two.

Oh, almost forgot. These computers have CS Flash on them! I’m totally going to learn it some time.

Great unexpectations

The exam today didn’t go as well as I expected… I didn’t do horribly, but not as well as I hoped when walking in. They decided to abandon the judicial creativity quest completely, which messed up our revision. We were told, and understandably so, that judicial creativity was a topic that always came up, 100% of the time. And it did since the beginning of this subject. Today though, they decided to miss it out… Instead, I had to do justice, and just make up a tonne of stuff. I’m more curious than worried about if I’ll have the grades to get into university now… I hope I will. If not, I have next year to reapply and maybe retake an A2 unit or something, part time.

In Warcraft news, I really wanted to do Deadmines tonight, with Ratio, but my connection is being so stupid.

I went to the job center today! I felt crappy going in, like I failed at life or something… I know there’s nothing wrong with using the service, but I don’t feel like it fills its purpose since both my dad and mum have been going since… well, ever. I was pleasently surprised though; there are tonnes of jobs all listed on a touch screen computer and you can print off the details and stuff. I even though programming, PHP and HTML jobs. I printed a bunch off and I’ll start working on those Monday. I’ll probably start this weekend, but I doubt I can do anything (like phoning them up and stuff) till Monday.

Apparently, I’m entitled to job seeker’s allowance, but I really don’t feel like I’m entitled to it. I mean, I am seeking, but I’ve not given the government any money at the moment, so I feel like I’d just be 100% selfishly using other people’s tax money to fund my non-productive lifestyle…

A clear outlook

I only have one exam left now, which is one that I’m expecting to be hugely easy so I’m not at all worried about it. Getting an A in it would be awesome though… It’d definitely help me out with UCAS points, since I’m really worried about those at the moment. Looking at my AS results, I really don’t feel like I can get what I need for Brighton – which is a near impossibility – I might just scrape DMU, which is a sucky thing to say since I slated them for giving me a really low offer… I guess the main lesson I’ve learnt with A Level is that even if you think they’re likely to be easy, you still have to put in the effort. Kinda like even if you’re a level 42 hunter, if you take on six level 30 you’ll probably get beaten.

I’m not at all worried about getting into university though. The way I see it is that I’m likely to get into DMU. If I miss that, it really won’t be by much, in which case I can fight my way through clearing. If all fails miserably, I’ve still got all of next year to reapply. I can even resit an A Level unit or two if I really have to, not getting into university won’t push my timetable back at all.

The problem of this being my last exam though is that I’m actually unemployed once it’s over. Dad’s nagging me that my child support money will stop in September so I’ll have to get a job to pay him the money he’s losing out on. What I think he meant though was that I needed to get a job in order to pay him board money. Which is really a dumb thing to say, since I’m hoping to have moved out of this house long before September anyway. I just have to start looking for a job now; I’m not really sure where to start though. I’ll make an appointment at the Job Centre tomorrow, I guess.

Meanwhile though, I’ve bought shamess.info and I’m using part of that to advertise freelance, hosting and SEO services I can start offering. That’s something I wanted to do before, but never really had time in between World of Warcraft and college. Now it’s just World of Warcraft I can start focusing on that full time, till I get a job, then I can focus on it full time.

Side note: I’ll start to move this blog over to shamess.info too soon (probably tonight) so things may get a bit confusing, since I’ve never migrated a WordPress blog before. I figure I won’t touch the files, and just change the ServerName. Hopefully, most people won’t even notice the URL change, if I set it up right.

Oh, also, I’m going to start updating DebianTips again. It still gets okay traffic for a neglected blog. I need to touch up some of the older posts with stuff I’ve learnt new though, before I start doing more stuff.

Taking a break

I had my law unit two exam today, and I think I did fine.

I’m not even thinking about my next exams (next, next Friday), so I’m having a break from worrying this week. Meanwhile, I’m gonna learn how to do drag and dropping HTML/Javascript. There don’t seem to be much helpful sites around.

To-do for law 2

I have a law (unit 2) exam Friday. That gives me four and a half days to learn it all. Well, not all but a good chunk of it. I’m … not exactly confident, but still, I’m not considering suicide.

I figure when I get back home (I’m at my mom’s at the moment) I’ll start a vigorous revision cycle. Unit two consists of four 15 mark quests, they’re pretty predictable too.

• What do magistrates do
• What do judges do
• Advantages and disadvantages of judges
• Advantages and disadvantages of magistrates
• ADR methods
• Advantages and disadvantages of ADR

So, if I learn those, I’ll do fine.

Today has been productive

Don’t be fooled into believe that I love to tell you all what I’m doing every second of the day, I’m actually only here because World Of Warcraft is doing for maintenance. Why do they take off every realm at the same time? I thought I’d play my dwarf (PVP server) whilst my main is down, but that goes down too. Sucks. So now I’m here.

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.

Why noone gets any work done on these computers

I’m using a college computer, since Niimo is busy with his being fixed and all. These computers are terrible. Really, they’re horrible.

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.)
