The car for the journey :

Rain in Zagreb:

Snow in Munich...

Next morning to Nürnberg to the Embedded world (geek expo :biggrin. You can always find interesting cars on the Autobahn

Probably the new X3


Some stuff from the Embedded world

Interesting stuff fore someone who plans to produce a car :tongue:

Geek quiz :biggrin:

Originalne Nürnberger Bratwurst

Switzerland

And a little more snow

Geneva

It was too crowded so my photos aren't the best...

One of the few exhibited EVs that has a WORKING powertrain...

Chinese EVs:

That's me :tongue:

Porsche's dual motor for the front wheels:

This red little thing is a Croatian EV

Here is how a typical EV prototype looks like from the outside:

And now non-EV stuff:

What a beauty :biggrin:

One day I have to convert a Pagani Zonda. It's the most beautiful car for me

Engineering porn :biggrin::

Stunning coverage. It had to be overwhelming. What would you say the count was for full BEVs and PHEVs?

What was that one at the end with the swirly white framework?

Thanks for sharing. I appreciate all the work.

Hi vfx.

I guess that there have been 20 BHVs and 20 PHEVs. But only 3 or 4 BEVs that are ready for the market and and one PHEV (Toyota Prius).

The car with the "swirly framework" (it's not the car's frame btw) is a Alfa Romeo - Bertone concept car.

The fair was a lot bigger last year and Frankfurt is even much bigger. I have to see them all every year

Return p, not s...

This works:

#include <malloc.h>
#include <string.h>
#include <stdio.h>

char * copyandreverse(s)
char *s;
{
int i,j, length;
char *p;
length = strlen(s);
p = malloc(strlen(s+1));
j=length-1;
for (i=0;i<length; i++){
p = s[j];
j--;
}
p[length] = '\0';
return p;
}

main(argc, argv)
int argc;
char *argv[];
{
printf ("Copyrev: %s\n", copyandreverse(argv[1]));
}

% ./copyrev CopyAndReverse
Copyrev: esreveRdnAypoC

You are lucky the forum doesn't just allow 4 images per post anymore!

You can see the Alfa Romeo name on the door sill, and their logo on the wheel hubs...


By the way, the Zonda in bare carbon fiber is quite something.

 

[DaveD]

How comfortable are you with the p = malloc(strlen(s+1)); statement?

 

[bolosky]

This works:


% ./copyrev CopyAndReverse
Copyrev: esreveRdnAypoC

It works, but only because you're lucky. There's a buffer overflow: p = malloc(strlen(s+1)) allocates 1 FEWER bytes than the length of s, not one more, since the +1 operates on the string pointer, not the size. They meant to write p = malloc(strlen(s)+1).

We take our buffer overflows seriously here at Microsoft! (Not that we seem to be able to get rid of all of them!)

 

[bolosky]

How funny! Dave and I (both Microsoft employees) found the same bug at the same time.

Thanks for the great photographs and coverage of the show.

One observation: Did you notice the BYD charging station and how the screws on the cover are crimping at the holes? If that is any indication of quality fit and finish from that company, it will be interesting to see what is done on the car, both on the physical fit and finish and on the actual electronics and mechanics. Interesting.

 

[TEG]

OK, so I don't work as a programmer anymore! I guess my neighboring structure didn't mind an extra byte intruding for a moment. Plus my ancient unix machine doesn't seem to have any bounds checking enforcement enabled to let me know that the app was participating in some risky behavior.

It works, but only because you're lucky.

(As Clint Eastwood says to me... did you allocate 6 bytes or only 5? Feeling lucky, punk?)

 

[AJC]

How funny! Dave and I (both Microsoft employees) found the same bug at the same time.

Shouldn't you two be working?? :tongue:

 

[DaveD]

They meant to write p = malloc(strlen(s)+1).

Personally, I'd rewrite it as p = malloc(length+1); since that's computationally more efficient, plus it reads better, IMO. But, modern compilers would probably eliminate that extra strlen() call, regardless.

@AJC: This is work! Spreading the word about buffer overflows is a duty that should never be shirked, no matter where they are found.

Fantastic coverage; love the heads up display in pic 4; happy days!

The feeling and physical quality is horrible. I was thinking that the car is high quality since I was reading a lot about it and it seemed to be a decent car but I'm really disappointed. You can't sit normal in the car, especially on the rear seats because of the battery in the bottom

The plastics in European cars form the 70s look better than this

But I like the high power charging station. It actually works! Not like all that mules that European companies are presenting

What's funny is that when I asked them about the charging station I was told that that was the "medium power charging station" if you wanted "high power" you'd have to get a different station.
