 Cool Stuff :D

The Elan/100, like its predecessor the 10/10s, works with an optional Barcode Reader E accessory. This was an experiment in simplifying the camera’s user interface for novices. Or, to be less charitable, an expensive gadget-driven idiot mode.

Basically it works like this. You get a booklet of barcode settings, each illustrated by a photo. (the scanner shipped with a small booklet of barcodes, EOS Photo Files, but Canon also sold a companion volume - EOS Barcodes 101 - stuffed with even more useful and exciting barcode settings!) The photo will be of a typical setting - a backlit item or a flower or a landscape or whatever. You look at the item you want to photograph, flip through the book until you find a similar photo, scan the barcode from the book and then input the barcode into the camera. The barcode is then used to program the camera.

Hacking the barcodes.

The barcode reader wasn’t a very popular feature. In fact, it really was a fundamentally flawed concept from a marketing standpoint - the only people who’d really want such a feature would be rank beginners. However, because of the cost of building the system, only fairly costly midrange cameras supported it. So Canon quickly dropped the barcodes - the 10/10s and the Elan/100 were the only ones bearing this dubious capability. However, there is one handy thing about it. And that is tied to the key word “programmable,” the hacker’s favourite word.

Basically, inquisitive people have figured out how the barcode system works and have written small programs so that you can write your own custom barcode programs. These programs let you design your own custom PIC modes - sometimes even accessing camera functions not available through the camera’s external buttons and dials. You then print out your custom barcodes on your PC or Mac (the camera uses Interleaved 2 of 5 formatting). This can be lots of fun to play with if you happen to be a geek.

See http://photonotes.org/manuals/eos-elan/#barcode for more - fantastic website and yeah I'm ignoring his copyright notice here, but hey I do not care for US or whatever law and I think it is fair use ;)

Given was:

def fizzbuzz(num):

> if num % 15 is 0: return fizzbuzz(num-1) + 'fizzbuzz \n'
> elif num % 5 is 0: return fizzbuzz(num-1) + 'buzz \n'
> elif num % 3 is 0: return fizzbuzz(num-1) + 'fizz \n'
> else : return fizzbuzz(num-1) + ('%d \n' % num)
> return ''
> print fizzbuzz(100)

Since this was not funny enough, I wrote:
for i in range(1,101):print('','fizz')[not i%3]+('','buzz')[not i%5]or i

This works because not casts to bool and (True, False) == (1, 0).

This works because not casts to bool and (True, False) == (1, 0).
It also exploits short circuit evaluation and the fact that the or matches against the result of + due to evaluation order, where '' would yield False.

I guess I should give perl another try someday to get this in a half line :)

It was a radio quiz and I was live on air - funny feeling.

They played a short audio sample of a movie and I had to guess the title of the movie.

Well, what should I say... I knew the title in the first two seconds because I heard "Verpasst du auch nem Mann ne Fussmassage?" - And that's of course the german wording in one of the best scenes in one of the best movies ever made - Pulp Fiction

Lucky me they picked this one ;) I won a CD and now... back to work :)

Yes, you can slice your psd and it will display in your browser, so obviously it is possible to implement what you design?
really? Think about it...
just look at the "code" you generate with this method.

And ever thought of *dynamic* content being displayed? And no, I won't constuct an image and slice it on the server side..

Heck, do you realize what evil hacks are necessary just to get the rounded borders on this page? Tons and tons of clientside Javascript render these. Yes, on the client. Yes, on every pageview. No, there is no compatible way of doing this with HTML/CSS until all browsers out there know CSS3.
Billions of billions of billions lines of Javascript get interpreted by home computers every day, wasting energy and computing time just because you guys want rounded borders and did not know how complex this is to implement.

If you feel adressed by this text: You may call yourself designer, but please dont call yourself webdesigner. You'll lie to yourself, to your customer, and that poor little bastard who'll have to translate your .psd into HTML/css will curse you, use evil hacks, will get blamed for things not working and taking too long. He might kill you.

Real webdesigners know what's possible and work with what they have. Sadly this is practically limited to HTML4 und CSS2, but things will soon get better with HTML5 and CSS3.

]]> Force samba to tell accumulated share size http://pronweb.de/node/85 2009-12-20T16:32:27+00:00 2009-12-20T17:04:08+00:00 ch3ka I wanted to backup my win7 on my fileserver, using the builtin backuptool and CIFS.
However, I have one big share where some cryptofilesystems are mounted, and samba will only tell the size/avail of the root directory which is exported, thus Windows thinks there is not enough space to do the backup.

Fortunately, you can force samba to tell an arbitrary sharesize with the dfree command.

I wanted samba to tell the combined size/avail of all filesystems currently mounted under my share, so I wrote this script:


filr ~ # cat /etc/samba/dfree
#!/bin/sh

I wanted samba to tell the combined size/avail of all filesystems currently mounted under my share, so I wrote this script:


filr ~ # cat /etc/samba/dfree
#!/bin/sh
df /enc* | tail -n +2 | sort | uniq | awk '{blocks +=$(NF-4); avail += $(NF-2)}; END {print blocks " " avail}'

and made it executable and told samba to use this for calculating the shares size/avail:

filr ~ # grep dfree /etc/samba/smb.conf
dfree command = /etc/samba/dfree
(in the [global] section)

And thats it. How does it work? the df - command matches all currently mounted cryptovolumes (as they all begin with /enc* here), tail -n +2 strips the first line of df's output (that would be the header), sort|uniq catches non-mounted Filesystems, and the awk command extracts the columns for blocks and avail and sums them up.

Now Windows sees the "correct" size and usage of the share, and will hopefully be able to backup now.
