Implied HTML elements, CSS before/after content, and the link HTTP header combines to make a document that displays something despite having a 0 byte HTML file. Demo only in Opera/FireFox due to link HTTP header support.
What Target discovered fairly quickly is that it creeped people out that the company knew about their pregnancies in advance.
“If we send someone a catalog and say, ‘Congratulations on your first child!’ and they’ve never told us they’re pregnant, that’s going to make some people uncomfortable,” Pole told me. “We are very conservative about compliance with all privacy laws. But even if you’re following the law, you can do things where people get queasy.”
Space Quest II remake and a Space Quest 7!
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))
{
...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);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.
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.
A bug came up the other day involving markup containing <input type="image" src="http://example.com/.... I knew that "image" was a valid input type but it wasn't until that moment
that I realized I didn't know what it did. Looking it up I found that it displays the specified image and when the user clicks on the image, the form is submitted with an additional two name
value pairs: the x and y positions of the point at which the user clicked the image.
Take for example the following HTML:
<form action="http://example.com/">
<input type="image" name="foo" src="http://deletethis.net/dave/images/davebefore.jpg">
</form>http://example.com/?foo.x=145&foo.y=124.
This seemed like an incredibly specific feature to be built directly into the language when this could instead be done with javascript. I looked a bit further and saw that its been in HTML since at least HTML2, which of course makes much more sense. Javascript barely existed at that point and sending off the user's click location in a form may have been the only way to do something interesting with that action.
I had previously replaced my use of Delicious with Google Reader. Delicious had a number of issues during their switch over from Yahoo to the new owners and I was eventually fed up enough to remove it from daily use. I used Delicious to do the following things:
Of course I wrote this and switched over about 1 week before Google removed the sharing feature from Google Reader. I'm irritated but in practice it forced me to find a different option which has worked out mostly better. New blog post coming soon about that...
I'm trying to learn and use PowerShell more, but plenty of other folks I know don't use PowerShell. To allow them to use my scripts I use the following cmd.exe batch file to make it easy to call
PowerShell scripts. To use, just name the batch file name the same as the corresponding PowerShell script filename and put it in the same directory.
@echo off
if "%1"=="/?" goto help
if "%1"=="/h" goto help
if "%1"=="-?" goto help
if "%1"=="-h" goto help
%systemroot%\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -Command . %~dpn0.ps1 %*
goto end
:help
%systemroot%\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -Command help %~dpn0.ps1 -full
goto end
:endAdditionally for PowerShell scripts that modify the current working directory I use the following batch file:
@echo off
if "%1"=="/?" goto help
if "%1"=="/h" goto help
if "%1"=="-?" goto help
if "%1"=="-h" goto help
%systemroot%\system32\windowspowershell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned -Command . %~dpn0.ps1 %*;(pwd).Path 1> %temp%\%~n0.tmp 2> nul
set /p newdir=
