I watched Piranha again this evening. In this film is a scene in which our heroes find themselves racing to reach a waterside summer camp before the razor toothed horror arrives. It’s a very tense sequence and much of the tension derives from the fact that this is an exploitation film.
Had this been a mainstream film, I would have been watching safe in the knowledge that children and animals will never find themselves in real peril and, therefore, that the heroes would arrive in the nick of time. Piranha, however, is an exploitation film – produced by Roger Corman to cash in on the success of Jaws. And because it’s an exploitation film, all bets are off.
You don’t know whether or not the heroes are going to arrive in time. And it’s this that makes that particular sequence particularly nail-biting.
Pawel Kuczynski graduated from the Fine Arts Academy in Poznan with specialisation in graphics. Since 2004 he has been creating satirical and thought-provoking illustrations that comment on social, economic, and political issues. I particularly like this one, and you can find many more on Pictorem.

If you follow my Quitter stream, you will be aware that this year’s horticultural efforts have been less than stellar. One bright spot, however, is that the blackberry bush I planted appears to be surviving.
The first blackberry of the year
The escaping chicken will be so happy when she finds this.
Here’s something I didn’t know.
I have used Vim to write text files in the past and, when I do so, I use
aspell check to catch my multitude of typing errors. It turns out that Vim is also able to support spell checking, so I no longer need to keep dropping back to the command line.
Joe ‘Zonker’ Brockmeier goes into detail, but I am reposting the highlights here so that I can easily find them again.
:setlocal spell spelllang=en_gb turns on the spell checker.
:set nospell turns it off again.
[s moves to the next and previous spelling errors respectively.
z= brings up a list of alternatives for the typo under the cursor.
zg adds the word to the dictionary.
zw allows you to mark a word as incorrect.
This post was entirely written in Vim.
Stated very simply, I face reality and admit that not only isn’t there anyone at home upstairs, there isn’t even any upstairs. I have one life and I intend to make the most of it. Therefore it follows naturally that if I firmly believe this, why then I cannot deprive another person of their turn at existence. Only the very self-assured political and religious zealots kill people in order to save them.

I also like this bit (from the same Hutton Delusion post) on the value of life:
Like diamonds, like gold, like principled politicians and non-libertarian hard SF, life is precious because it is an irreplaceable and finite commodity. Those who assert an eternal afterlife do not, as they claim, give our lives more worth and more meaning. They turn them into meaningless, relatively short precursors to the main event.
In fact, the whole post is worth reading. Go take a look.
Someone hasn’t quite cracked the whole heroes in a half shell thing yet…
Belgian politics are wonderful
Kamikaze Belgian Government?
The inclusion of the liberals opens the way for talks on the formation of a centre-right federal government with Flemish nationalists, Flemish Christian democrats and Flemish liberals. The Francophone liberals will be the only Francophone party in what has been dubbed the ‘Kamikaze Government’ as it does not possess a majority among Francophone lawmakers and in Francophonia the Francophone liberals will have to carry the can for everything.
Informateur Charles Michel is reporting back to King Filip in the course of today. It’s likely he will step aside. He can propose which parties can form the new federal coalition government. A Flemish Christian democrat could be appointed as formateur to form the next federal government.
Marc Van de Looverbosch: “The Flemish Christian democrats could propose outgoing Flemish PM Kris Peeters as the new federal Prime Minister. In this way the Christian democrats are not squeezed between the nationalists and the liberals. He is a figure of compromise. The Francophone liberals of MR will be able to say they are not entering an administration dominated by the Flemish nationalists.
The Kamikaze coalition holds 85 seats out of 150 in the federal parliament, but only 20 seats are held by Francophones.
Firefox 31 hit the Arch repos at some point today and now I have it. Since Mozilla moved to their 42 day release cycle, most of the changes from one release to the next have been incremental and not really worth noting. But I did notice something new when I opened a new tab.
That search bar immediately above my most recently used tabs is new. And handy.
And, for the borg-averse, you can change your default search engine by clicking on the logo. This gives you a drop-down showing your currently installed search engines and an option to manage the same.
Raju Varghese (via Sploid) claims that if you fold a piece of paper 103 times, the thickness of your paper will be larger than the diameter of the observable universe: 93 billion light years. The explanation is simple enough – every time you fold a piece of paper you double its thickness and when you start doubling things they get very large very quickly – but I couldn’t leave this without checking the numbers for myself.
Of course, I couldn’t resist checking this for myself and pulled out a calculator. I soon found that the mental juggling needed to get from fractions of millimetres to kilometres was too much for my little brain and converting between millimetres and light years was going to be impossible.
So I wrote a script. The code is pretty simple, as you can see below, although I did have a four fold discrepancy when I first ran it (I came up with 107 folds needed, rather than 103). It turned out that my initial thickness of the paper was out by a factor of 10. Once I fixed this, everything matched.
Calculates the thickness of a piece of paper after n folds """
thickness = 0.1
folds = 0
meter = 1000
kilometer = 1000000
lightyear = 1000000 * 9000000000000
size_of_universe_in_mm = 93000000000 * lightyear
while thickness < size_of_universe_in_mm:
thickness *= 2
folds += 1
if int(thickness / lightyear) > 1:
print(folds, int(thickness/lightyear), 'light years')
elif int(thickness / kilometer) > 1:
print(folds, int(thickness/kilometer), 'kilometers')
elif int(thickness / meter) > 1:
print(folds, int(thickness/meter), 'meters')
print(folds, thickness, 'mm')
And then, with a slight edit, I dumped the results into a table so that I could add a few comparative distances.
||Taller than the average human
||Taller than The Shard in London
||We’re now standing higher than Mount Everest
||Now we’ve just passed the Moon
||And the Sun
||And finally we reach Pluto
||6 light years
||With a single fold, we have shot past Alpha Centuri
||107460 light years
||And now the thickness of our piece of paper is larger than the Milky Way
||3438722 light years
||And in a few short folds, we pass Andromeda
||112680053353 light years
||And with that final fold, we have exceeded the size of the Universe
Exponentiation is awesome.
