Normally I comment out lines in a Windows batch script by prefixing them with “::”—it just looks better to me than “REM”. But today I found out the hard way (of course) that you can’t do that inside an IF block, or the script dies with… The syntax of the command is incorrect. http://www.petri.co.il/forums/showthread.php?t=43604
I’ve often been confused and frustrated by conditionals ( … ? … : … ) in SSIS expressions. The concept is straightforward enough, but the syntax made it really hard for me to keep track in nontrivial cases. Then yesterday I had an epiphany: it’s much easier to keep them straight if you write themContinue reading “SSIS Conditional Expressions (Lightbulb:On)”
I just ran across this great bit of advice I got back in 1995 from Larry Wall, creator of Perl: Don’t get brainwashed by your education into thinking that all the answers have to come from teachers.
I’m experimenting with a new kind of post, where I simply make a connection between two or more ideas, usually with little or no commentary. Here’s the first one: Ed Felten, yesterday: CALEA II: Risks of wiretap modifications to endpoints Today I joined a group of twenty computer scientists in issuing a report criticizing an FBI plan toContinue reading “Connection: Wiretap Laws”
I have had a thought. This is the content thereof. Disappointed yet?
Organizational culture emerges from the process of answering questions. The answers aren’t necessarily articulated explicitly, but they’re expressed in the decisions people make, the way people treat each other, and in so many other ways. Organizational leaders may be unconsciously undermining the very culture they’re trying to create, but they can’t change it until theyContinue reading “Better Questions”
When Steve Gibson talked on Security Now 398 about how few users’ Java plugins are actually up-to-date, this question hit me: Should browser plug-ins have built-in expiration dates? The problem with having all of these old Java versions running around is that attacks always get better. How much more sophisticated are the attacks of todayContinue reading “Time Limits on Browser Plugins?”
Yesterday’s lesson in bug hunting: don’t assume you’re an idiot. I spent a few days trying to figure out why my success callback wasn’t being called. It had been working before I updated to jQuery 1.9.0, and I didn’t think I had changed anything. After much head scratching I found out that jQuery 1.9.0 introducedContinue reading “Lessons in Bug Hunting”
I wanted to GET a lot done today: /coding, /writing, &more; But try as I might, I got 302, and /time returned 404.
I launched a new intranet application today. Nothing fancy, just a simple app to address a real need in my organization. Initial feedback has been very positive. Feels good to ship!
In light of recent events, I wondered if anyone was making a connection between gun control and the regulation of strong encryption. So I googled it and found that someone had: me, two years ago. Related: why do so many news reports use the term “gunman” (emphasizing the noun; Google News has 2.49 million results inContinue reading “Gun Control and Strong Encryption”
I recently made a salad that everyone in my family loved so much we made another batch the next day. I don’t have precise measurements, but this will get you started: 12 ounce can white tuna, drained A decent squirt of ranch dressing (enough to bind the tuna together, but not enough to make itContinue reading “Recipe: Tuna Salad”
Heads-up! In MySQL, WEEKDAY(‘2012-11-09′) = 4 (0-6 starting on Monday), but in SQL Server, DATEPART(dw,’11/09/2012′) = 6 (1-7 starting on Sunday). If you’re extracting data from MySQL to load into SQL Server, the correct translation is ((WEEKDAY(date)+1)%7)+1.
If you’re not asking the right question, then there is no correct answer. Merlin Mann in Back To Work #41
Here’s another product parody Lars and I did in college: Washingsoft UAnix. This was born out of our frustration with the way the University of Washington had—shall we say—embraced and extended standard Unix functionality.
Aaahhh, the joys of Photoshop and free time. I just stumbled on this little trip down memory lane—a parody of a Microsoft Office box that my roommate (Lars Blacken) and I did in college.
To force IE to edge mode (even on intranet sites, where IE would otherwise use compatibility mode), the server needs to send X-UA-Compatible as an HTTP header. Using a meta element in the document head doesn’t work reliably. I found the answer buried in this Stack Overflow thread. In my case, I was working onContinue reading “How to Override IE’s Compatibility View Behavior On Intranet Sites”
When I wrote about my experience setting up AD Single Sign-On for Linux, I said the next step was to extend the transparent SSO experience into WordPress. The biggest reason for that—I thought—was so that the WordPress server could then impersonate the logged-in user to pull resources from our SharePoint server (using SharePoint Web Services)Continue reading “Single Sign-On Epiphany”
Digging into a web portal application. It uses Ajax … and frames. 17 years of Web history, all on one page. (I didn’t know browsers still supported frames.)
