Building a USB 3.0 Peripheral
It’s interesting to think about how to do this. Linux is so amazing because this support is: Included the Linux 2.4 kernel as part of USB Gadget Driver Android includes the drivers so that any Android build can use USB-on-the-Go PLX 3380 is a registered compatible 2280 (the USB 2.0 version) USB3380EVB is a PCI…

SFF PC or how small can a computer be…
Well done with big file servers for now, what about really small systems with great graphics. The new Haswell-E has allowed building really small units: Gigabyte BRIX Pro is a good example. For $600, you get a 8-core Core i7 with its embedded graphics. Sure it’s loud but kind of amazing that with a 135 watt…

New Haswell file server: Memory and Cooling addendum
This will get incorporated into the new Haswell file server post but it’s big a bulky on the topic of DDR4 and LRDIMM: DDR4 DDR3 has been around forever and the stock ones are typically 1600MHz but range from 800 to 2200MTs, but DDR4 starts at 2100MTs eventually up to 4200 Mts! As an aside…

SSD decoder ring and Haswell file server rect
Well that post is getting longer and longer and here are some additional notes: SATA drives can plug directly into a SAS backplane. Wow that is pretty cool the so if you have an SAS motherboard, you just need SAS cables to the backplane Storage with SSDs The future of course is moving to PCI…

Poodles and SSL
It seems like it never ends. Here’s a new problem with SSL using SSL v3 encryption. You have to make sure to disable it in your browser or check the site to make sure it doesn’t accept it. Firefox has an add-on that turns SSL v3 off. Chrome has a command flag. There isn’t any…

Aoyue 968A is the coolest
Got to love the internet, got just the coolest solder and hot gun engine today. Of course there are no directions that make any sense, so thank goodness for Youtube, with lovely musak, here’s how to assemble it! See https://www.youtube.com/watch?v=_NUqV2tGApg

Building a cool Haswell File Server
I haven’t built a machine in a while and have never built a dedicated file server box. So lots of great learnings from the exercise. We’ve used first Mac Mini with Drobo and then Synology (nice embedded product), but now it’s time to go all the way to Linux with ZFS so wish me luck. Here…

Sweet spot for microSD moving from 16 to 32GB
It is incredible sometimes how prices fall. Just a few months ago the sweet spot for pricing was the 16GB microSD card. You could get those for about $10. Now the pricing curve for a Class 10/UHS-1 (so a decently fast card at 10MBps) is: 8GB: $8 16GB: $9-12. Amazon seems to have really low…

Dying hard drives…WD makes it easy
Well it seems like hard drive failure month for me. Here are the drives, for personal machines, we are putting SSDs in as they are much faster and more reliable iMac 2009. Yuck, this one is going to be hard to get out. It’s buried and I have to figure out how to get the…

Can your Mac run OS X Yosemite? Find out here
Given how tough the last releases have been particularly with iOS 7.0 and 8.0 and Mavericks (which seemed pretty rough), I have to say I’m surprised by how smooth 8.1 and Yosemite have gone. Seems like it runs the same if not faster on old hardware. Our venerable iMac 2009 seems to like it (albeit…
