New Toys

Arrived today, 4x WD20EARS-00MVWB0, WD Greenpower 2 TB, 3-platter, 64MB cache, 4 KiB physical sectors. These will go into the server as a RAID5 volume to extend the current 4x WD10EACS RAID5 Volume Group.

Also, I went and bought myself an iPhone. This is a secondhand 3G, 8GiB, black, model, running currently 4.0.x jailbroken & unlocked. It's cute and it'll tide me over until my white 4 finally arrives.

[Edited to add] By popular demand, also a pic of my Twisty Puzzles collection, as a sequel to the previous Rubik's post.:

First, receive a package from Dealextreme (Note: SKU 21524. Colour is unfortunate, bui it is by far the easiest way to get a Cube4You cube), and open it up:

Then curse, as you realise that they've included 13 edges and 7 corners in this one, instead of 12/8 as it should be. Hope that this is the only one. Be relieved, as you open the next one. Start by filling in all the edges and cornes (most cubes will only have fill-in pieces for the corners, not for the edges):

Fun fact: According to that last photo, these were manufactured in November '09, getting on for a year on the shelf now.

Next, assemble the core. Note the spring direction particularly -- these cubes have a built in washer on the screw, and a wider end on one spring, so you don't need a washer there either. Most cubes will come with straight springs and one or two washers per screw, If just one, washer goes between spring and plastic to reduce wear. A good starting point for setting the tension for me seems to be (with tension outwards) to leave about a millimeter's worth of room between the core and the centers, so very nearly fully screwed in.

After that. the actual assembly of the cube:

Once you've assembled the cube, leaving center caps off, it's time to check tension. This is a matter of taste. Looser means faster, but also means more chance of the thing falling apart on you during a solve.

Once the tension seems right (don't worry, you can always change it later -- and very easily even, with this particular model), give it some twirls, and once it loosens up a bit, sticker it and then lubricate it (spray silicone) for best results. Lubricating first and then stickering is not recommended, as the lubricant may cause the stickers to not adhere properly.

Result!
