The infinite information publisher theorem

We know for a fact that with a earth citicent count of

I got about this far, and I had to fix wikipedia for a math error. It had this”{{#expr:({{worldpop}}/1000000000) round 4}} billion.”
going on, it should of course be round 3.

where was I? Right; ..we have populated this world of ours with 6.769 billion humans, and counting (fast). At this point we are about 1 000 000 internet users in the world, many of us blog, or some way or another publish text, music, images, source, math or any kind of information. Given that the amount of published information will keep on rising for as long as human kind stay around, this will eventually be one big bag of information all together.

How long do we (the human kind) aim to stick around? I know we are doing our best to brake the world, but what if the next generation, and the next one again, somehow manages to *not* ruin the world? Will the number of humans ever existed keep on rising into infinite? Do we aim for infinite, or can anyone tell me the date we aim for?

“oops, sorry kids.. I broke the world.”

If an infinte amout of internet users publish random information, for an infinte amount of time we will most likely eventually see two bloggers blogging the same, without copying eachother. We will most likely see to musicians creating the exact same tune. We will see an extreme amount of tunes almost the same, millions of blogs nearly identical. We will also see an infinite number of published ideas, most different, but many the same, or nearly the same.

Really; it should have been called copywrong.

Of course, much of this publishing would be illegal due to the unnatural copyright laws of today, but that will change.. someday. I am sure you can think of a way to help out on this one.

Infinity is a long time, but we should at least aim for the future, right?

Buying limits

I must admint, I don’t see why anyone would buy themselfs a set of limits. Look at the limitations of Windows 7 starter:

  • No Aero Glass, meaning you can only use the “Windows Basic” or other opaque themes. It also means you do not get Taskbar Previews or Aero Peek.
  • No personalization features for changing desktop backgrounds, window colors, or sound schemes.
  • No ability to switch between users without having to log off.
  • No multi-monitor support.
  • No DVD playback.
  • No Windows Media Center for watching recorded TV or other media.
  • No Remote Media Streaming for streaming your music, videos, and recorded TV from your home computer.
  • No domain support for business customers.
  • No XP Mode for those that want the ability to run older Windows XP programs on Windows 7.
  • No rights to read, reuse or change any of the source code.

Good luck with selling that then!

If you would like no limits instead, you could go for something open source, like Ubuntu.

Regnskogfondets skjermsparere

Regnskogfondet har laget en skjermsparer til Windows, hvor nydelige naturfotografier tatt av biolog og fotograf Thomas Marent vises frem. @regnskogfondet på twitter ba i går om hjelp til å få laget OSX og @forteller ønsker en Linux-variant.

Her er:

Regnskogfondets skjermsparer til Ubuntu

– Den funket fint her hos meg, men trenger test og tilbakemelding fra deg! Last ned, pakk ut (høyreklikk og velg pakk ut), og dobbeltklikk på setup. Du må velge skjermspareren etterpå (brukervalg, skjermsparer, Rainforest).

Regnskogfondets skjermsparer til Mac OSX

Denne trenger jeg hvertfall tilbakemelding på, for jeg har ikke fått testet den enda 😉 Jeg hadde ingen OSX-installasjon for hånden.. Last ned, pakk ut og kjør setup. Du må velge skjermspareren på vanlig måte etterpå.

Dette er bare et par kommandoer i en miniskript, så det er lett å få det til å passe til flere distribusjoner.

PS:

Fint om du støtter regnskogfondet, kjører mindre bil, bruker sykkel, buss og tog i stedet, sorterer søpla di (herregud – det tar ikkeno lengre tid), panter flasker og ikke kaster gamle datamaskiner som virke,r men installerer linux på dem i stedet.

Binary-coded decimal-coded sexagesimal/quadvigecimal time notation

I have been looking for a binary clock for my Gnome desktop, but I did not find what I was looking for. I did find some examples for binary clocks, and there are a lot of different solutions for this, but none of them was what I wanted.

Screenshot of my desktopSo here it is, my variant of a binary clock. Here it is shown in prism on my Ubuntu desktop. It reads HHMMSS, like 14:56:19. If your math needs a refresh, here we go:

In binary notation we have only two states, 0 and 1. So this means that when the number you notate exceeds 1, you will need a new digit, and the first one is reset to 0. This is exactly the same way our decimal system works: after 9, comes 10, only in binary 10 comes after 1 already.

In binary, you count 1, 10, 11, 100, 101 and so on..

In the decimal numeric system the value is given like this:

23

and it means

2*10+3
The same number can be represented in binary
10111

and you can read it as

1*16+0*8+1*4+1*2+1

Typed this way, the time 23:48:19 would be printed:

10111:110000:10011

Cool enough, but more used is a different way of printing the time. I guess it’s the 6-digits needed for minutes and seconds that made someone come up with this other way of typing it. In this case each decimal digit will get a corresponding binary number. Like this:

23
10 11

This is what we call binary-coded decimal. It is simpler to read, because it easily translates to decimal numeric system.

Funny thing, time itself is coded in a special way, where seconds and minutes are decimal-coded sexagesimal (it goes up to sixty), and the hours are decimal encoded quadvigecimal (the 24 hour clock, the 12-hour one is duadecimal).

Bottom line is that this clock is binary-coded decimal-coded sexagesimal/quadvigecimal. Lets just call it binary coded decimal clock to keep it simple.

Oh, I almost forgot: http://hitthebutton.org/bcdc

Update: That word.. quadvigecimal.. I might have just made that up.. If you know, please tell me 🙂

Putting two words together

In Norwegian we put together words to make new words. We have a grammar rule for when to separate two words that together creates a meaning, and it goes like this:

Never.

Now thats quite easy to remember, so in Norwegian “grammar rule” is “grammatikkregel”, “rubber tire” is “gummidekk” and “guitar buddies” is “gitarkameratene”.

For quite a while Norwegian press has referred to a band as “de nye gitarkameratene”. The musicians first using the name “Gitarkameratene” now reacts to this, claiming that it’s disrespectful to use this word that they “invented”.

For me, I have a problem with this. I mean, if the word was something like “Kraputtvoltgitarkameratene”, surely, this *IS* a new word, but just putting together two common words, creating another common word is something we all *should* be doing according to Norwegian grammar rules, hence such a word can not be owned by anyone.

To make sure this kind of stupid debate rises once again in the future I wrote a small script to fix this.

for i in $(cat words.txt) ; do
    for j in $(cat words.txt) ; do
        echo $i$j
    done
done

I ran the script on a Norwegian dictionary, but I didn’t bother to remove all the double words first, so many entries are now put together by 3 or 4 words.

Anyway the output file is about 2TB, so I can’t post it here, but if anyone can lend me some server space, I’ll publish this new word list on the conditions that everyone can use any word in this list as they want forever.

– But I will always know that I created many of these words first 🙂

Internet Explorer er farligst

tu.no skriver at Firefox er farligst. Dette er basert på en rapport som er laget av Secunia (i februar?) for å oppsummere sikkerheten i nettlesere for året som gikk.

Det er vrient å vurdere “farlig” for nettlesere, men antall sikkerhetshull som er tettet sier mest om hvor mange sikkerhetshull som er tettet, og lite annet. Som om Per og Ola skal rette sine egne stiler, så retter Per 20 feil og Ola 4. Hvems stil er best? Umulig å si ut fra det.

Rapporten har med en annen tabell, som viser hvor lang tid det har gått fra et sikkerhetshull har blitt allment kjent (slik at du og jeg og Vladimir kan utnytte det) til det har blitt tettet.zeroday2008

For Firefox del, så gjelder dette to feil som er kategorisert som “ikke kritisk”, samt en feil som er kategorisert som “mindre kritisk”. Den mindre kritiske feilen tok 15 dager å fikse, de to andre henholdsvis 30 og 86 dager.

For Internet Explorers del ser det noe svartere ut. Tre lavrisikofeil er overliggere fra 2007, og er ikke med i tabellen engang. Værre er det at Internet Explorer en moderat og en svært kritisk feil, som begge var åpne i hele 110 dager. I tillegg var det tre mindre kritiske feil som var åpne i 78, 231 og 294 dager, samt en ikke kritisk feil som var åpen i 233 dager.

Norwegian police force computers may be hacked more than once

If you still want to use Windows for your home computer, that is OK, because its only your own data and it will not affect many users if you get hacked. Last, but not least, its you, not the tax payers that have to spend money fixing it when it happens. Windows may also run some of your games best.

One public service after another gives away the control over their computers to criminal hacker groups. The list keeps getting longer and includes military defence, police force, hospital and other critical institutions. All of the infected computers running Windows, and it seems to be a global issue.

Make no mistake about this – when a computer is infected with malware, it’s all up to the writer of the malware to decide what should be done. Usually the goal is creating a large botnet, but it could just as easily erase all data on the computer, or even upload data from the computers to an internet server. Or just implement a backdoor for later use.

The Norwegian police’s computers has been infected with Conficker a few days now, and they try to calm down people with saying that this was not a targeted attack. Right. THIS what not at targeted attack, but the fact that this automatic attack uses a well known security hole, with published PoC and everything you need means that anyone with the ability to use Google could create their own attack in 1-2-3.

How to hack unpatched computers in 1-2-3:
1.Select your favourite exploit, you can find hundreds of them.
2.Copy and paste the proof of concept code into your little malware
3.Attack and hide.

What we know is that bots have been walking around inside our police offices, and the reason is that the doors has not been locked. The same doors have been open for anyone, who else has been inside since October? We could never know…

If you do this targeted, you will remain undetected for a LONG time unless you screw anything up. The antivirus software will not detect a targeted attack, because they only look for known malware signatures. You know; I bet that the IT-department of some of the institutions that have had their doors unlocked for months now didn’t even reinstall everything on all the computers that have remained unpatched for months, but only removes the malware and updates Windows. So if you hacked the computers a while ago, you can still remain undetected. The doors may be locked now, but you already created your own well hidden backdoor.

How to stay undetected in 1-2-3:
1.Hide your backdoor in existing files
2.Do not mess with anything. Make a copy and mess with the copy.
3.Do not remote control a computer while its in use

Oh, another thing. The Norwegian police force states that they still are working with removing Conficker (Monday afternoon). I hope they don’t have any of the unpatched computers connected to anything, because these are open as a open door as we speak, or type, or read. I mean; I type – You read.

This is really serious. Systems so targeted for malware, and so hard to maintain should not be used by public sector. Yes, I say hard to maintain. If you installed Debian in 1996, you could still run it and have it patched. If you run Windows from 1996, you have to have reinstalled at least once, preferably twice, and bought new hardware at least once, again preferably twice.

Another issue is, that swapping to Linux for public sector would not only be safer, but also cheaper and more reusable.

Many countries are already doing this with success, so why shouldn’t we all? The French police are migrating all 90.000 workstations by 2015, and even if they only moved 5.000 so far, they have saved 50.000.000 Euro in licensing and maintenance costs.

Cheaper, safer, simpler, better. Who decides that we still stick with Windows? This is a political matter, and politicians say go open source, yet (almost) nothing happens.

The work with getting rid of closed source in public sector needs to accelerate before public sector is owned by hackers or script kiddies.

Who would like to hack the police, or the hospitals? I can think of a few groups:
1.The botnet makers
2.Criminals looking for stuff to blackmail others on
3.Kids fooling around

I guess there are more groups, but this should be enough to start locking the doors. Right?

Would hacking for good be bad?

Some years ago hacking was about fun, learning and freeing information. Then came the fame, and suddenly it turns bigtime, and these days its all about the money. Incredible many computers are remote controlled by criminal hacking groups to spam the rest of the world, stealing passwords, performing denial of service attacks and more. Imagine all this computer power used to search for stolen computers and illegal material on infected computers.

Yes, I know – there is a privacy issue. The irony is that privacy has left the building, years ago. You leave an electronic trace around everywhere, to be used and abused. And the creators of malware – they basically own your computer at some point or another.

In an action movie the idea of all computers all over the world starting to mailing the police if illegal porn was found would be a great idea. In the real world I guess we have to stick with computers mailing you about penis enlargement and the big lottery you won.

There might be some gray areas as well. Like looking at a computers MAC-address to see if it is stolen. To check the MAC-address of the wireless network card, you do not have to look into the computer, since its visible from outside.

When its about wireless networks, its much like driving down the street looking at other peoples houses. If you see into a window, and you think what you might just saw was some illegal activity, its probably your duty to have another look, and call the police if you still believe there is some illegal activity. On the other hand, f the shades are down, it would be illegal for you to lift up the shades to have a look. Even though the radio waves of a wireless network is much similar to the light rays that comes out of the neighbors window, these waves is not visible to your eyes, but to your computer. If the network is open, a script could have a quick look and email the police, and it would be good, but if there is a WEP, and your script breaks this key first, it would be bad. Right?

Fikse en dvd som ikke virker

Lang kveld i kveld, så ungene skulle se på en film de fikk til jul, bare at den i DVD-spilleren lagde en fæl ulåt og ville ikke spille. Lar det seg enkelt gjøre å fikse en ødelagt DVD? Jeg undersøkte nøye DVDen, og den så helt fin ut. Men den virket litt unormalt glatt akkurat der hvor DVD-spilleren skulle ta tak og spinne opp DVDen. Mulig spillerens gummiring som tar tak i platen skulle vært rengjort, men det lar seg ikke gjøre i en fei. Jeg tar litt tannkrem, Colgate Total Whitening som gjør jobben denne gangen, ved å slipe litt på den innerste blanke ringen på DVD-platen. Etter det har blitt klint tannkrem på DVD-en er det bare å vaske og tørke den forsiktig og vips så fungerte den helt fint.

Tidligere så har jeg hatt nytte av en annen tannkrem med litt mindre “korn” i, for å ta bort små riper på platen.

Etter alt det strevet med platen. kanskje du får en suss?
