Heise is running a story, reminding us on the ten years anniversary of the burst of the .com bubble. Where about ten years ago the stock value of overrated, mostly internet related companies became penny stock overnight.

I can not stop, but think we will soon see history repeating itself with all those web 2.0 companies, such as Facebook or Twitter. I mean how many millions, and billions are they pumping into them without any reasonable revenue, or just even revenue model in sight?

Sure, at last they can all go down the advertising road. But is there really enough space for them to grab a multi billion share of the ad-market? And 2020 we will be all living from advertising?

Somehow, I do not really see this adding up.

Five years and the wait is finally over–Poker reduced the price to a tenths

opensnoop didn’t really cut it, so here we go:

syscall::open*:entry
{
printf(”%s %s”, execname, copyinstr(arg0));
}
syscall::stat*:entry
{
printf(”%s %s”, execname, copyinstr(arg0));
}

For years the German flagship IT trade-shows loose visitors. The Systems is now even history. And last year the Embedded Word and CeBIT managers were as stupid to use the same date for the shows???

Our company used to visit the Embedded World as guests. We always where considering to exhibit there, as we did on Linux shows, or the CeBIT. For our start-up every year it became more likely to join the Embedded World, however all abruptly stopped last year when (IIRC) the Embedded World for the first time happened to be the same days as the CeBIT.

It is certainly bad enough to loose visitors to competing shows overseas, such as the Computex or CES. But how can those regressing shows steal each other’s exhibitors and visitors? In the same country, week.

I doubt we are a single incident here. Like us certainly many more have partners at the other show or would like, or have to exhibit on both. There should be at least some days gab between the shows, to make it possible for more to attend both shows. This would still allow foreigners to optimize their travel schedule and visit both in one go. Another, I think even better, option would be to have half a year between both shows. For example move the Embedded World to the autumn. To better match product cycle and product placements.

But on the exactly same days? Hello???

The Apple Mac OS mouse cursor speed is one of those “love it, or hate it” domains. Personally I find the default speed already way too slow, always falling asleep on a fresh Mac install, or at the login window.

The max used to be barely endurable, so far, e.g. with the Mighty Mouse - until I got the Magic Mouse the other day. Directly compared the Magic Mouse moves way slower with at the same setting. No idea how Apple got this inconsistency in their own, few products. I also have no idea why mouse pointer movements can possibly be that slow. Not only the default, but also the maximal configuration value, …

Fortunately there is no limit behind the back, so you can tune it with:

defaults write -g com.apple.mouse.scaling -float 8

The 10.6.2 maximal UI value appears to be 3, …

Update: Some more review: The slowness aside, the Magic Mouse is pretty decent. The biggest improvement over the Mighty Mouse is the touch sensitive cover. The former microscopic scroll ball was prone to accumulate dirt inside and near to impossible to clean. (To really clean and remove dust and dirt from the ball axes one hat to cut(!!!) the glued mouse housing and disassemble it fully, …). So from this usability standpoint it’s a great improvement. The major downside is, that only a Bluetooth version is available. I personally find the weight of the two AA batteries too hefty - that was also already a problem with the Bluetooth Mighty Mouse. For my excessive workdays I would prefer a lighter, cabled version to reduce the wrist stress, …

Well, these days most news sites just publish the press releases of product announcements. Or re-tweet news from other sites. Personally I find really authentic, journalistic work such as the recent Tom’s Hardware video driver, 2D blitting vs. Windows 7 review particularly outstanding. Heck, they even wrote their own performance metric test utility for it!

With r35579 I just added the (very tine) required build script configuration and glue to let the T2 SDE (System Development Environment) build script use clang and clang++ as the default C and C++ compiler. And I just successfully compiled the first packages on a x86-64/T2/Linux test build:

The resulting ssh and screen even worked as expected (so far, anyway).

ExactCODE just released another major ExactScan product family update: the new version 2.9 brings vast improvements all over the App. Most notably are excessive image processing performance improvements. For weeks we did nothing else but revisit our algorithms and fine tuned line of code that stood out.

With years of solid foundation code at ExactCODE, ExactScan already was pretty solid. However, even we received reports about issues. So likewise, for months, we where tracking every single stability issue brought to our attention. All of this contributes to making the version 2.9 the most performing and stable release, ever.

It even comes with new, built-in scanner drivers. For example the new Avision D2 models are now all supported, e.g. the AV220D2+, AV320D2+, and various other (yet unreleased) models, even various other vendors.

Of course work continues on the next planed updated, 2.10. For this next, of course free, update we even have another major surprise for you. Stay tuned, it’s just some weeks of QA away.

Day, life could be so great:

!> ./configure: line 14867: syntax error near unexpected token `$SDL_VERSION,’
!> ./configure: line 14867: `AM_PATH_SDL($SDL_VERSION,’

Damnit.

To quote David S. Miller:

“whirrr, whirrr, whirrrrrrrrr…”

That’s the sound my brain makes when I’m working on low-level sparc code.

Well, it’s also the sound my brain makes when I look at this macros, of macros of generated and M4 processed script fluff. Just that low-level OS, SPARC, etc. code is certainly more entertaining, educating than this useless piece of sh*t script.

Update: And just because your compiler is accidentally not named “gcc”, or “cc”, you end up with gibberish like:

libtool –silent –mode=compile clang …
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `–tag’

Your system keeps telling you a locale is not supported by your system’s C library? For example:

svn: warning: cannot set LC_CTYPE locale
svn: warning: environment variable LANG is en_US.UTF-8
svn: warning: please check that your locale name is correct

or:

firefox: (process:4376): Gtk-WARNING **: Locale not supported by C library.
Using the fallback ‘C’ locale.

or even while compiling software, such as:

setlocale(LC_CTYPE,”en_US.UTF-8″) failed!
make: *** [extra/locale/c8tables.h] Error 1

You can use “localdef” to add them to the cache from the verbose source definitions:

localedef -i en_US -c -f UTF-8 en_US.UTF-8
