Headlines are flying around this morning that a “serious security flaw” (now dubbed “Covert Redirect”) has been discovered in OAuth and OpenID, which could be exploited by malicious sites to capture user’s personal data. Furthermore, the “reporting” includes comments from major auth providers (Google, Microsoft, Facebook) to the effect of “we can’t fix this”. Synopsis: […]

From the Vault

Arno Van Jaarsfeld posted a photo of his old Turbo Pascal floppy disks recently. In the spirit of “show me yours”, I reached under my desk and pulled these gems out of “the vault” – a hardside diskette drawer/box that has followed me through many moves. Left: Turbo Pascal 5.5 (1989) Right: Turbo Pascal 4.0 […]

As I build out the network in our home and other buildings on our farm property, I’m rapidly becoming a fan of Power over Ethernet. I got interested in it for the normal reasons (placing wifi access points in places without easy access to power) but now that I have it I’m finding additional perks […]

The OData specification committee at Oasis released the new OData 4.0 draft spec at the end of May. It covers a lot of ground, and there was no “what’s new” high level summary available when the draft was first published. TL;DR mobs sprang up in discussion forums brandishing pitchforks and torches. In an email on […]

Forrester analyst Andras Cser has proclaimed XACML is Dead. Unfortunately, the data used to justify this proclamation is flawed at many levels. Disclosure: I am the architect of the XACML 3.0 PDP authorization engine at the heart of the Dell/Quest Authorization Policy Server product, and I am a member of the OASIS XACML technical committee. […]

Reports are making the rounds of a “huge attack” targeting web sites running WordPress. I noticed suspicious behavior in the IP access logs of one of my web sites a little over a year ago. I turned on logging of failed login attempts to get a better picture of what was happening. I checked the […]

Great googly-moogly. I’ve been fighting with a variety of services on one of my Windows machines for several weeks. Windows updates have been deadlocked since mid August. Some troubleshooting guide suggested disabling Windows Firewall temporarily until the updates could complete. Not only did disabling Windows Firewall not resolve the Windows Update issue, but Windows Firewall […]

Dell has completed the acquisition of Quest Software. We are now Dell! It has been a busy year or so. I joined BiTKOO in October 2010 to help expand and scale BiTKOO’s push into the nascent XACML external authorization space. 14 months later, Quest Software acquired BiTKOO in part to fill a gap in Quest’s […]

First Cast Glass

I’ve wondered for awhile whether my old electric kiln could manage the long slow heat soak required for glass casting. Flat kilns with heating elements in the top are recommended for hot glass work because a) a lot of glass work is flat (plates, windows) and b) heating large flat pieces of glass from the […]

Stage 2 of my personal Own Your Words quest has been completed. 75 articles I wrote for the Delphi Compiler Core blog from 2003 to 2005 while at Borland are now republished here on my personal site. You can find them all in the Delphi Compiler Core category. This archiving task was considerably more of […]

In the spirit of Own Your Words I recently completed importing all 81 articles I published on my “Windows Live Quantum Mechanics” blog on MSDN while I worked at Microsoft in the Windows Live development group (2006-2007). These articles are now archived on my personal web site under the Windows Live Quantum Mechanics category. I’d like to give […]

I learned the “Own Your Words” mantra the hard way several years ago. I’ve blogged on technical topics under a number of banners and web sites over the years. My blog moved twice while at Borland as new/better blog services came online every few years. While at Microsoft I was delighted to have the opportunity […]

Broadening Horizons

In the spirit of consolidating my online identity onto a server I control and actually own the content, I’m repurposing to include non-software stuff I’m into as well as the software and technology related stuff I’ve posted here for years. I have been intending to build separate sites for my various fields of interest, […]

A Tale of Two Bowls

These two bowls are made with the same stoneware clay, the same glazes, and the same firing temperatures and schedules. They were fired in the kiln together, side by side. And yet the colors are so distinctly different between the two. Why? The only difference between these two pieces is the thickness of the glaze […]

Green Rimmed Rivet Bowl

I’ve been trying to get a nice clean rim impression from my “circle dot” pattern wheel for ages. We don’t have failures, we just have lots of practice and educational opportunities. Clay too wet/sticky, too much pressure, not enough pressure, uneven distance from the rim, and worst of all the tail not meeting up with […]

Green Rimmed Doodle Bowl

As I was finishing this bowl with a saturated iron teadust glaze I idlely swirled a finger around in the goop puddling in the bottom of the bowl.  Who doesn’t enjoy a finger swirl in goop every now and then? I didn’t realize my brief moment of doodling would create a distinct indelible pattern in […]
