Recently my eyes have been a little strained using the computer. I think it probably has something to do with the misplacement of my reading glasses somewhere at University. Hopefully I’ll find them before my Mum finds out and goes nuts lol.

Anyways to reduce browser related eye strain, I found a handy script for Greasemonkey (in Firefox) that kinda inverts the webpage/makes it less white and a bit easier to read (higher contrast). Its not perfect but it’s a handy hack until I can do some more hunting for my glasses!

Anyway enough text, here’s the links:

Invert web page colours (lifehacker)

Direct link to Greasemonkey script

Options are customisable, so you can restrict the websites it works on…

Oh, and here’s a screenshot:

Simple fix/hack – make Firefox save PDF files rather than open them.

1. Open Options (Tools \ Options in Windows and Edit \ Preferences in Linux)
2. Open the Applications tab
3. under ‘Adobe Acrobat Document’ change the value of the dropdown to ‘Save file’

1. OK the change
2. All done. Hopefully that’s one less annoying crash to worry about!

Ps get Session manager to save yourself loosing a window full of tabs or having to do a horribly manual procedure like recovering tabs from a accidentally closed Firefox window.

That’s all for today, I’m afraid. Not much else to talk about

Hopefully I’ll be able to produce some proper posts next week!

There are various reasons for this, mainly todo with connection speed.

What I have at the moment is:
#/bin/sh
terminator -x ssh user@site.com wget -qc -t 3 -o ~/wget_testlog ftp://anothersite.com/file.ext \\& \& &


I want it to kick off, ask for a password to login via ssh and then go away…
I would like to be able to set the location for the download to ~/www/files/

I was planning to place this script in /usr/bin and install it in firefox using the code/link provided on this blog: Wget from firefox

Can anyone complete my solution with the correct syntax, or provide a better solution (preferably KISS)?
I’m more of hacker than an expert IMO and I know when I’m out of my depth!

Cheers,

You may think when you visit, for example, bbc.co.uk that it’s just “there”, and not worry about how, but my job is dependent on the how. The error messages you see when a website isn’t working are also very descriptive, but quite cryptic if you’re not in the know.

All websites are hosted on servers. A server is just a computer which we use to serve others, so in this case, serve a website, or provide email services. Normally, a server is a rackserver, designed to fit in a small space with a lot of other computers in a datacentre, far, far removed from that big beige box that allows you to browse the internet.

When you visit a website, a lot of different things are happening in the background. Firstly, your computer looks up the computer address with the domain name you just visited. Say you just hit my site, “kirrus.co.uk”. Well, the internet addressing system, that tells your computer where to look for the website is based in numbers. So, your computer asks special servers on the internet, we call “Domain Name Servers”, what the address is for that website. In this case, they’ll reply “80.87.131.49″. Your web-browser, firefox, will then ask for “kirrus.co.uk” from my server “80.87…”). Everyone has one of these IP addresses, even you. Go to http://itempeter.com to see yours

Once my server has the request, it then sends the web-page back to your computer.

What is a webpage?

A webpage, as your computer sees it, is a collection of a couple of languages. The most basic is “HTML”, or “HyperText Markup Language”. This was designed to allow you to quickly put together a webpage – all you do is wrap (or mark up) the text you want with the flags you want. For example <b>word</b> tells your computer to make word bold, so, you see: word

You can see the HTML that makes up this page by clicking on “View” and then “View Source” in your web-browser.

That’s the most basic level. It gets a lot more complex than that under the skin, with extra languages running on your computer (JavaScript, CSS [Cascading Style Sheet]), and on the server (PHP – PreHypertextProcessor, ASP, perl, python, MySQL) but they’re all too complex to go into unless you want to create dynamic websites. A good place to go if you want to create webpages is w3schools.com, where they have lots of tutorials on all the major web languages.

Can I just say.. bad bad bad bad bad bad bad?

That and they have no idea how much this will cost to implement. £2bn is too little imho. Technically, implementing this will not be easy, and will cost a lot

On my machine, it and my graphics card drivers just don’t seem to get along. It crashes when anything interesting (or too busy) happens on my screen. A lot. The other week, it crashed whilst I was doing the utterly uninteresting task of mining (I set it go, and then go about doing something more interesting, like studying, whilst keeping half an eye on it to make sure I don’t get blown up), but more often it crashes whilst I’m trying to do something more interesting, like helping blow other people’s space ships up.

This game is interesting, in that you are effectively immortal, dying isn’t a problem. The only rule is, only fly what you can afford to loose.

Still fun game

I can give out 21-day free trials, if anyone wants one, let me know. (Disclaimer: If you sign up, I get 30 days free play )

If you’re looking for a console application to give you a quick heads up on the transfer speeds across a network interface have a look for ifstatus (not to be confused with the ifplugd suite) .

If you’re looking for something to log and display network statistics checkout vnStat

Minor niggle: both these programs needed compiling and required additional dependencies which I recall were GD, for the graph creator of vnStat (vnstati) and curl for the console interface of ifstatus.

If you have any other suggestions, queries or points, please leave a comment!

Altered Carbon cover courtesy of Amazon

I finished Altered Carbon, the first book by Richard Morgan, Sci-fi, a couple of days ago. It’s taken a few days for my ideas upon it to crystalise..

It’s a complex weaving book, very, very good for his first. The plot moves thick and fast, set in an ugly futuristic society. The technology of the sci-fi not that new, but its a novel implementation.. what happens when humans can be digitally stored, but set in a plot. My most stringent criticism would be that the primary character shows borderline superhero syndrome, or of being a “superhero” in a world that should have none. Mostly explained in the story well, but borderline. If I want to read a superhero story, I’ll go read a superman or batman comic

The book touches on our societies current quest for immortality, and it’s something I’ve thought of recently as well. Our society is broken, and still reeling from the changes that computers have brought upon it. We can now communicate a lot further a lot faster than ever before. It is unlikely, that had I been writing this 20 years ago, that this post would have been able to exist, let alone be able to be read by people living almost anywhere in the world. We seem fixated with our human needs; you just have to go on google, and be a little careless to bring up an example of rule 34 ¹ .

Believing as I do in a world beyond this, seeing everyone so fixated on their needs now, rarely thinking about others, rarely thinking about the future beyond their deaths hurts. Some humanists are changing this, and I am probably using too big a brush in some cases, but still.. worth thinking about possibly.

A couple of screenshots. Firstly, every now and then, people send us screenshots. They do this by sending them in word documents, which is bad enough. (Please, just send us an image file!) This example though, is quite fun.

Make sure you actually copy the screenshot in, instead of just linking it

Example 2 – Infect yourself, and pay money for the privilege

My second example, is of a website trying to extort money, by making you think your computer has been infected with a virus. These are nasty sites, and I hate them with a passion. They feed off of people’s fear of computers. The interesting thing here is, this computer can’t be infected in this way… it’s running ubuntu, their silly antivirus software looks very, very out-of-place!

(See my first post this month if you’re afraid of computers.)

Click on the image for the full screenshot. It is quite large. As you can see from the timestamp, I’ve been meaning to post this one for a while

p.s. Does anyone know how to force formatting in wordpress? This post took about 10 minutes of fiddling to get the images to go some-where near where I wanted them :/ If you do, please comment! If you don’t please comment. In fact, please comment, comments make my day!
