I asked +Simon Stuart‚Äč “can you make your Raspberry Pi 2 devices crash by flash light?” he did: it fails!

Posted by jpluimers on 2015/02/09

Too bad: it is indeed possible to restart a Raspberry Pi 2 by using a high power flash.

It appears that U16, the SMPS chip, is the culprit.

Yes, bit of bluetac on that chip and it survives the flash

Source: Raspberry Pi ‚ÄĘ View topic – Why is the PI2 camera-shy ?

Simon Stuart checked it:

it’s true!

Put the high-power flash (which I believe uses a Xenon bulb) on my camera, and behold a shot to the top of the board does indeed crash it every time!

Never in a million years would I have thought such a thing were possible!

At first Simon could not reproduce it: you really need a high power flash.

I’m glad I didn’t order any Raspberry Pi 2 yet.

Hopefully Embarcadero will publish official guidelines to make the IDE High DPI aware…

Posted by jpluimers on 2015/02/09

With the common-place of High DPI it is surprising the IDE hasn’t gotten more love in this respect.

The VCL can do it (Dalija Prasnikar knows an awful lot about Delphi High DPI), but the IDE can’t yet¬†(it is *****^H^H^H^H^H very irritating¬†that you need to login to see quality portal reports¬†though apart from Google not being able to index them: the main reason I don’t file bug reports any more –¬†QC is no alternative as it it is more or less defunct –¬†but I digress).

With Delphi turning 20 years old this week, hopefully Embarcadero comes out with official steps to make recent versions of Delphi XE* High DPI aware.

Right now there is only some hearsay it might work: Does anyone have idea about how to make Delphi IDE (XE7) support High DPI…

PS:

High DPI awareness is must have feature for XE8.

Not only for Delphi IDE, but also for VCL and FMX frameworks.

How to Prevent a specific Blogger Blog from Redirecting to Country Domains

Posted by jpluimers on 2015/02/09

The article How to Prevent your Blogger Blog from Redirecting to Country Domains describes to prevent the country redirect from within a blog itself.

But what about outside readers that want to see a specific blog on the .com link?

One of the reasons they want to do this is that Google does not index the country redirected sites, they only index the com site.

I had this while reading¬†http://delphisorcery.blogspot.com/. It kept redirecting to http://delphisorcery.blogspot.nl/¬†(as I’m based in Amsterdam; in Germany for instance it would redirect to¬†http://delphisorcery.blogspot.de/).

But a site:delphisorcery.blogspot.nl search would return nothing whereas site:delphisorcery.blogspot.com would return the full index for the blog.

The trick is to browse the .com version of the blog with NCR once: http://delphisorcery.blogspot.com/ncr

If you do that, Google forces a no-country redirect (just like you can do with Google.com: browse to http://www.google.com/ncr), and it remembers that choice too.

Note that BlogSpot has not done this country redirect for ever.
