FTA: “Nick Bilton put the FAA’s claims regarding Kindles and airline avionics to the test. The result? They emit less EM interference than planes are required by law to withstand.” Much less, apparently.
I’ve heard of hover previously. Sounds like a good place to go.
FTA:
The MPAA is getting pretty desperate, it seems. MPAA boss Chris Dodd was out trying to defend censoring the internet this week by using China as an example of why censorship isn’t a problem. It’s kind of shocking, really.
“When the Chinese told Google that they had to block sites or they couldn’t do [business] in their country, they managed to figure out how to block sites.”
Public site that tracks who (by IP address) downloads what and lets anyone view this.
“One in three people in Switzerland download unauthorized music, movies and games from the Internet and since last year the government has been wondering what to do about it. … The overall conclusion of the study is that the current copyright law, under which downloading copyrighted material for personal use is permitted, doesn’t have to change.” Wow, that sounds like almost reasonable and understandable copyright law.
“including driver updates to enable Internet sharing on some models such as the HTC HD7” Just upgraded and saw this. Very cool.
The following code compiled just fine but did not at all act in the manner I expected:
BOOL CheckForThing(__in CObj *pObj, __in IFigMgr* pFigMgr, __in_opt LPCWSTR url)
{
BOOL fCheck = FALSE;
if (SubCheck(pObj))
{
...
I’m
calling SubCheck which looks like:
bool SubCheck(const CObj& obj);
Did you spot the bug? As you can see I should be passing in *pObj not pObj since the method takes a const CObj& not a CObj*. But then why does it compile?
It works because CObj has a constructor with all but one param with default values and CObj is derived from IUnknown:
CObj(__in_opt IUnknown * pUnkOuter, __in_opt LPCWSTR pszUrl = NULL);
Accordingly C++ uses this constructor as an implicit conversion operator. So instead of passing in my
CObj, I end up creating a new CObj on the stack passing in the CObj I wanted as the outer object which has a number of issues.
The lesson is unless you really want this behavior, don't make constructors with all but 1 or 0 default parameters. If you need to do that consider using the 'explicit' keyword on the constructor.
More info about forcing single argument constructors to be explicit is available on stack overflow.
“TechCrunch and others are reporting that a program called “Carrier IQ” that comes pre-installed on Sprint phones has some pretty amazing spyware capabilities, right down to keylogging everything you do on the phone.”
Last time I wrote about how I switched from Delicious to Google Reader's shared links feature only to find out that week that Google was removing the Google Reader shared links feature in favor of Google Plus social features (I'll save my Google Plus rant for another day).
Forced to find something new again, I'm now very pleased with Tumblr. Google Reader has Tumblr in its preset list of Send To sites which makes it relatively easy to add articles. And Tumblr's UX for adding things lets me easily pick a photo or video to display from the article - something which I had put together with a less convenient UX on my bespoke blogging system. For adding things outside of Google Reader I made a Tumblr accelerator to hookup to the Tumblr Add UX.
Of course they have an RSS feed which I hooked up to my blog. The only issue I had there is that when you add a link (and not a video or photo) to Tumblr, the RSS feed entry title for that link is repeated in the entry description as a link followed by a colon and then the actual description entered into Tumblr. I want my title separate so I can apply my own markup so I did a bit of parsing of the description to remove the repeated title from the description.
