Easy Come Easy Go

2007 Sep 14, 7:37I previously mentioned how much I enjoyed my new office. Well my team has moved to a new building and although we get more offices total meaning no one on the team has to share an office, this building has less windowed surface area which means less people get window offices. Since I received the window office recently I'm kicked out now in FIFO order. Stacks are so sad.microsoft work personal office nontechnical

Wikipedia Tools

2007 Sep 12, 6:54I'm visiting Wikipedia more and more recently but I always find myself reading the referenced webpages to get the full context of quotes and for more info. Basically I use Wikipedia as an introduction and a place to look for links. For times when I'm looking for opinions rather than facts I like to use Everything2. No need to check references there.

There's the much hyped WikiScanner tool which reports who has been making anonymous (thought to be anonymous at the time anyway) edits to Wikipedia. Its humorous and interesting in a few cases, but in general I think its stretching to say that because an IP address range is owned by a corporation and someone edited Wikipedia on an IP in that range that you can attribute that edit to that corporation. If I edited Wikipedia I'd probably do a bit of that during my lunch break, but that wouldn't mean that Microsoft wants the Wikipedia pages for Weird Al, Dave Risney, URIs, or whatever else I would edit on Wikipedia changed.

Also, via Everything Is Miscellaneous I found the tool Wiki Dashboard. Wiki Dashboard proxies Wikipedia and on each page shows a timeline view at the top with who made edits and when. Its nice to see a gentle curve down from an initial spike at the beginning for topics you don't imagine to be controversial. As the canonical test page for this service I looked up 'Elephant' the Wikipedia page Stephen Colbert suggested folks vandalize on his show on 2006 July 31st. If you look at the Wiki Dashboard Elephant page you can see a very large spike in edits on that date. That's all I need to see.

As a side note, for the link on Stephen Colbert suggesting folks vandalize Wikipedia I linked to a Wikipedia article. Is it inappropriate to provide info about Wikipedia being vandalized and thus incorrect via a link to a Wikipedia article?wikidashboard stephen-colbert wikality wikipedia wikiscanner colbert-report

Two-for Script File

2007 Aug 6, 5:40I was messing with the XSLT to XSL Converter source which is a javascript file that can be run with cscript.exe. I've changed it to be like a very basic version of xsltproc that simply runs an XML file through an XSLT. I also wanted to run this from the command prompt without writing "cscript ..." everytime. I decided to make like perl programmers I've seen and make a JS file that works as a batch file and a JS file at the same time.

Here's a basic version of what I ended doing applied to a 'hello world' script named helloworld.cmd:

/* 2> NUL
@echo off
cscript /e:javascript /nologo "%~f0" %*
@goto :eof

    Hello World
        Says 'Hello world.' when you run it.
*/

var outText = 'Hello world.';
WScript.Echo(outText);

Running this on a command prompt gives the following:

C:\Users\davris>helloworld

C:\Users\davris>/*  2>NUL
Hello world.

However, after a little more experimentation I found this was slightly overkill for my purposes since if I rename the file to helloworld.js and just type its name like a command it is run by cscript:

C:\Users\davris>helloworld
Microsoft (R) Windows Script Host Version 5.7
Copyright (C) Microsoft Corporation. All rights reserved.

Hello world.

So this time I didn't need all that but if ever in the future I need to run a batch file then a JS file I can do it with one file...cmd js technical cscript batch xslt xsl javascript

Wp64 Issues

2007 Aug 6, 3:43Miladin told me about the Visual Studio compiler's promising option Wp64 that finds 64bit portability issues when compiling in 32bit. If, for instance, you cast from a (long*) to a (long) you get a W4 warning. However, the #defines are still set for 32bit builds. This means that other parts of the code can make assumptions based on the #defines that are valid on 32bit but generate 64bit errors or warnings.

For instance, in winuser.h the public published Windows header file there's the following:

...
#ifdef _WIN64
...
WINUSERAPI
LONG_PTR
WINAPI
SetWindowLongPtrA(
    __in HWND hWnd,
    __in int nIndex,
    __in LONG_PTR dwNewLong);
...
#else  /* _WIN64 */
...
#define SetWindowLongPtrA   SetWindowLongA
...
#endif /* _WIN64 */
...

In 64bit everything's normal but in 32bit SetWindowLongPtrA is #defined to SetWindowLongA which takes a LONG rather than a LONG_PTR. So take the following code snippet:

...
LONG_PTR inputValue = 0;
LONG_PTR error = SetWindowLongPtrA(hWnd, nIndex, inputValue);
...

This looks fine but generates warnings with the Wp64 flag.

In 64 bit, p is cast to (LONG_PTR) and that's great because we're actually calling SetWindowLongPtrA which takes a LONG_PTR. In 32 bit, p is cast to (LONG_PTR) which is then implicitly cast to (LONG) because we're actually calling SetWindowLongA. LONG and LONG_PTR are the same size in 32bit which is fine but if you turn on the Wp64 flag there's a W4 warning because of the implicit cast from a larger size to a smaller size if you were to compile for 64bit. So even though doing a 32bit or 64bit compile would have worked just fine, if you turn on the Wp64 flag for 32bit you'd get an error here.

It looks like I'm the most recent in a list of people to notice this issue. Well I investigated this so... I'm blogging about it too!wp64 technical 64bit compiler c++ visual-studio setwindowlongptra

Office with a View

2007 Jul 14, 3:12I've been at Microsoft three years as of last Thursday. It makes me feel old but on the bright side I've upgraded offices. I now have an office with a window. Its actually a coincidence that I got this office at the time of my Microsoft anniversary but I like to pretend. I've had a single office for only four or five months now so its a nice surprise that I'm moving into a single window office so soon.

Of course this move means I'll be leaving some things behind. For instance the hanging dry erase pen holder that I created out of office supplies I will leave attached to my old white board. My new office has fancy whiteboards with trays built-in (sooo fancy) so I know the person coming into my old office will make better use of my hanging dry erase pen holder then I would. I explained to him that the rubber bands need to be replaced every eight months or so and not to exceed the maximum weight restrictions.

Additionally, the office art masterpiece I created I will also leave behind. When Bill Gates was featured on the cover of Diversity Inc. for his amazing philanthropic acts many of us got copies in our mailboxes. I collected mine and some from the recycling bins and put up five of the covers on the wall. Eventually others added to it which was my intent, but I only started this when I eventually checked my mailbox a week or so after the magazine arrived so there weren't as many covers left with which to work. At any rate I ended up with eleven on the wall. I'll leave the interpretation of the artwork up to the viewer.microsoft personal office nontechnical

Ozzie

2007 Jun 25, 3:13I keep seeing 'Ozzie' on emails and such now due mainly to Ray Ozzie who is now the Chief Software Architect at Microsoft and his brother Jack Ozzie. Whenever I see his name I think of Ozzie from Chrono Trigger. He was one third of a trio of villains, the other two being Flea and Slash. I feel like I should be thinking of the Ozzy for which this Ozzie was named but I really don't.

My next thought on Ozzie is the Scottish guy who went to my high school. He'd shout 'Ozzie! Ozzie! Ozzie!' to which listeners were compelled to respond 'Oi! Oi! Oi!'. The wikipedia article on the chant has some thoughts on the origins but I suppose at Microsoft it could take on entirely new meaning. I really hope I'm someday in a meeting with Ray or Jack Ozzie and have the opportunity...ozzy personal ozzie random nontechnical
