[Tech News] Interesting technology

No. But for e.g. PDF format allows you to have a 2D "barcode", which 
can hold cca 64KB of data, or so I remember ....

64Kb?  the largest I've seen is about 2kb
The bar codes that you can get from Acrobat Pro are the same as used 
for online air tickets
I think it was in the mid 80s
I think Byte did distribute some software that needed a bar code 
to scan in .. perhaps Compute! did as well.  Bit too long ago to 
remember this now
Sure beats sitting for hours at a time typing in program listings!

QR code?

QR codes are not very dense
I'm just curious as to how they did it ...  to advocate using paper 
to backup data implies some dense encoding method
http://www.ollydbg.de/Paperbak/index.html
4kb is quite respectable https://www.safeberg.com/en/paperkey
paper is used in this case to archive your private keys

Interesting ... Paperbak allows for the printing of 3Mb of compressed 
C code onto one page

in Datamatrix definition is written capacity of max 2335 bytes per 
one symbol of size 144x144 pixels, with some inbuilt compression 
it can be 3116 ascii characters (readable chars are ess than 8bit 
encoded), scanner may read mutiple symbols at once. much more importand 
characteristics is using reed-solomon self repairing code to ensure 
readability up to 30% picture damage for each symbol.
easy to read description at www.grandzebu.net together with other 
barcode symbologies

A datamatrix can hold 2K per bar code .. so we would have to create 
a matrix of datamatrices to store the data we need on a page

funny how I am starting to like the guys at comodore usa !  :-o


when I read through the forum on their "fan" site, the guy in charge 
is quite level headed, knows the scene and actually embodies more 
of the spirit that went into the first commodore & amiga.   just 
do it.
he is getting bashed all the time and he replies with a good attitude. 
 I think he just was lucky (had the opportunity and will) about being 
able to license both commodore and amiga from the two different license 
owners at the same time.


If he can give me a better linux experience at a reasonable price 
I might just go and get one.   and yes... having a C64 cased PC *is* 
geeky cool.
the only problem is that they are not using any decent video cards 
in their machines, so that sucks big time.   sorry, but all of the 
intel cards are extremely sucky.   they don't even compare to 4-5 
year old mobile cards from ati and nvidia.

This new C64 caught my attention from a Yahoo! Finance article: http://finance.yahoo.com/family-home/article/112510/new-commodore-64-nyt
Let's see if they can actually ship a new machine.
I'm an old Commodore user. My first computer was a VIC-20. Learned 
BASIC on the VIC. Fun times.
It appears that the VIC Pro and VIC Slim are available for purchase 
now. -- http://www.commodoreusa.net/CUSA_Store.aspx
They ship with Ubuntu 10.04 LTS with the Commodore OS 1.0 to be mailed 
later. I can only imagine how much later.

Maybe RT could get Rebol pre-loaded on it ??
Or Red :)
I can just imagine taking this thing to the hospital outpatients 
to do my clinics :)

Hmm, Czech Republic. However - I wonder how does it differ to OpenCV 
library, which has quite extensive functionality?

There's even a book about it, it seems there is also C, C++, Python 
binding, etc.

So in the near future, we can buy microwave ovens, fridges, tv's 
etc. that isn't completely ready for market, but need upgrade afterwards, 
like with games today. That'll be fun! :-)

Many TVs today are the same. Many TV or DVD player "repairs" are 
really software upgrades.

Yes, and this tendency seem to spread to all electronic equipment.

If just we had resource economy ... ;)

if we had resource economy, we probably would have better things 
to do than stare at TVs. :-)

maby not... the stuff on TV would be much better  ;-D
and everyone would have a 60 inch OLED screen  :-D

which would still dissipate a lot of heat, so ppl might not want 
it just because it's bigger

I dont' mind the heat... it'll heat the house in one of the 9 months 
I need to   ;-)


bah, they can always get a smaller OLED screen... its still prohibitively 
expensive.

Wow. Recent ACM and IEEE issues have had a number of articles on 
just how fast we've moved to the cloud, and that it will only accelerate. 
They also discuss technical issues that need to be addressed, but 
I don't think any of them have said "the big cloud providers could 
go down for 30 hours."

A few weeks ago I couldn't upload to S3 for a number of days. I was 
gearing up to sort out some unknown new-version incompatibility when 
it just started working again

Even though my instances and EBS volumes were in the affected zone, 
I'm not aware of any down time for  me
Kaj, what were you using to try and upload?
Amazon are blaming some network issue .. EC2 didn't actually go down, 
but the EBS did.  There was some type of cascading failure possibly 
as some type of replication went out of control and used up all available 
storage.
