Dell, how I hate thee (let me count the ways)

A Dell "feature" that appears to be designed to force customers to use only Dell parts reduced the speed of a set of SSDs one of my customers installed on their rack-mountable R900 server by a factor of 1000. Before I get into this, there are some provisos. This server was using Linux kernel 2.6.32. The SSDs involved are Samsung 850 Pro SATA-style solid state disks. SSD is not quite ready for prime time in the 2.6.32 kernel; NVMe support was first added in 3.3, TRIM wasn't available at all until 2.6.33, and a ton of other things we all take for granted like the device mapper are part of the 4.* kernel. Consumer-level Samsung drivers bring their own issues. Despite what the knuckle-heads on Reddit have to say about the topic, the Linux kernel still blacklists queued TRIM functions from every Samsung SSD in the 8** series. As of the latest Github commit as of this writing for kernel 4.8 queued TRIM still doesn't work for these devices. More importantly, the R900

Building a new gaming PC (with some digs about NZXT)

Never let it be said that I do not support the aspirations of today's young people. My contribution to the next generation was helping a local teen build out a high powered gaming PC. It was my first time installing a closed-loop liquid cooling system (the  Kraken x61 ).  Building a gaming rig. Notice how decades of IT work has resulted in a Quasimodo hunch The highlights of the PC included the following:     - Intel i7 6700K CPU     - NZXT  Kraken x61 liquid cooling system     - Nvidia GeForce GTX 1080  graphics card     - ASUS Z170-E motherboard     - NZXT S340 case     - Corsair Vengeance LPX DDR4 RAM     - Samsung EVO 850 SSD     - EVGA Fully Modular GQ 650W power supply During build-out I encountered two issues that weren't the result of my own fumbling, shaky hands. One of these issues I think is forgivable and the other is not. The ASUS 7170-E motherboard and its associated BIOS is specifically designed with gaming and overclocking in mind. I&

Pandora account compromise warning message

Here is a copy of the email I was sent by Pandora to inform me that my account was compromised kindof but not really and it was totally not their fault. This is somewhat old news (I received this email July 6th) but the more copies of this online the better, IMO. There are a number of things about this email that irritate me. First of all, the email is so incredibly vague that I have absolutely no idea what happened. Someone, somewhere posted my Pandora username (email address?) on the internet along with, presumably, one of the bazillion passwords associated with it. Who posted this information? Why? Where was it taken from? Was it stolen from one of Pandora's infrastructure providers? If what Pandora implies in the email is true - that the compromise is completely unrelated to Pandora in any way - why are they sending me this email? Does Pandora scour the internet for the email addresses and account names of its many users? If Pandora had no responsibility for this

Stay classy, Microsoft

Someone more cynical than myself might think that Microsoft's sudden 66% decrease of OneDrive storage space is a bait & switch - give away the space for free until users become dependent, than take it away, threaten to delete it, forcing those who have become accustomed to the free service to pony up and pay.
