New Java Security Settings: More Proof That Oracle Hates You

by

I began the day yesterday updating to Java 7u51, after which absolutely none of my enterprise Java applications worked anymore. I could not reach the consoles of my Rackspace cloud servers. I could not open the iDRAC console on my Dell PowerEdge. They all exited with some error about the Permissions attribute not being set. Being the guy that I am I decided to search for the error. Turns out that 7u51 sneaks a major change in a point release: on the default Java security slider setting of “high” no applet may run if it’s self-signed, unsigned, or is missing the Permissions attribute. Unfortunately, that describes all enterprise software, at least all the current versions of things I’m using. This isn’t …

Critical Dell BMC Firmware Update

I always like to know what the problem is, figuring that the bad guys probably already know, and it helps me determine my priority for the fix. Moral of the story is that if your older Dell server …

Dell PowerEdge 12G Is Here

by

Over the last week there’s been a number of different posts about the new Dell PowerEdge models, the 12th generation (12G) of their server line. I was briefed both by Dell technical staff and by Dell executive staff on the Rx20 lineup and I took a few notes. I was mainly briefed about the Dell PowerEdge R620, R720, R720xd, which will be in the first wave of refreshes. The higher-end models, like the R820 and R920, and the cloud & HPC focused C-series, will be part of another release soon after, and reach into the higher-end E7 CPU models (8 way, 10 cores) from Intel. The new mid-range hosts are built around the Intel Xeon E5 CPUs, also known as …
