Virtual 5x5 Cube
Inell Krolick
The Rubik's Cube (3x3x3) is a cube shaped Twisty puzzle. It was invented in 1974 by a Hungarian professor named Ernő Rubik. Rubik originally name the puzzle "Magic Cube" however, in 1980 it was renamed after its creator and is generally known since as the "Rubik's Cube". During the 1980s, the Rubik's Cube became a worldwide sensation, and it is estimated that by the mid-80s, 20% of the world's population at the time had played with it - that's 1 in every 5 people on earth! Until today, more than 350 million cubes have been sold worldwide, and it is considered to be the world's best selling toy of all time. As of January 2021, the Rubik's Brand, which was formed around the Rubik's Cube and other puzzles, is owned by the Canadian toy corporation Spin Master.
The Rubik's Cube has over 43 quintillion possible permutations - that's 43,252,003,274,489,856,000 to be exact. This number is so high it even excceeds the number of seconds passed since the Big Bang!
Despite this fact, over the years a number of algorithms for solving the Rubik's Cube were published. Some of them are more straightforward and some are more complicated but result in faster solves. The current world record for solving the Rubik's Cube is 3.13 seconds, it was set by Max Park (United States) at the Pride in Long Beach 2023 competition.
Over the years, many variations of the Rubik's Cube have been invented and mass-produced. Some of the most famous ones are the Mini Cube, Rubik's Revenge, and the Professor's Cube.
Let's start with the white face. Try to form a plus sign on the top of the cube, matching the colors of the side stickers to the colors of the lateral centers. This step shouldn't be too hard, try to do this without reading the examples below.
First put the white corner that belongs to the spot marked with the upper arrow in either of the highlighted positions. Next repeat the algorithm below until the white piece comes to its desired destination.
Turn your cube upside down because we don't need to work with the white face anymore. We can insert an edge piece from the top-front position to the middle layer using a trick. Do the left or right algorithm depending on which side you have to insert the piece:
1. Hold the cube in your hand having an unsolved yellow corner in the highlighted top-right-front position.
2. Repeat the algorithm until this piece is solved.
3. Turn the top layer to bring another unsolved piece in the highlighted position.
4. Repeat R' D' R D until that one is also solved.
5. Do 3 and 4 for any other unsolved yellow corner.
A bonus thought: This might be a good chance to implement a new and even better desktop cube. I always thought it would be nice if we could have proper 3D effects for windows, such as being able to drag them in full 3D space like sheets of paper. It would be a different feature and unrelated to this discussion, but goes well with the thought of putting something better in place if an older alternative felt less than optimal.
I ve a SAPBW 7.1 at SP SAPKW70107. My problem is regarding SAP Remote cube. I ve a generic data source, the data source takes a data and returns data. When i try this by BW LISTCUBE t code i get data perfectly. But when i make a BEX query to do the same, it says no aaplicable data found. I tried debugging the query in RSRT t code and found that the data comes fine in the query and structures like . But it gets empty
I did my searching and I found out that no Virtual providers implementation guides show making query in bex on a any virtual provider, all stop at displaying data in the BW system. I would appriciate if anyone can help me to the best of their knowledge.
I believe the issue is related to SIDs generation because if I return to LISTCUBE and show data with SIDs, the list takes longer to return and the characterisitcs and SIDs are shown. THEN I can run a BEx query and get results.
But the problem was in not in the BEX but the difference in the way the BW extarcts data from Virtual Cube and the way the Bex gets data from virtual cube. The Datasource responds to the filters in the BW rsa1 as a second priority because it first brings in the data and then applies filter. But the Bex does this the other way round. It filters the data and then brings it in. This was causing the issue.
Yesterday, I was successfully created a virtual device and could switch it on and off without issue. I upgraded to 1.12.0 today and the device stopped working. I recreated a new virtual device with a new GUID but any device I create goes offline immediately.
After the iHost reboots, the IP address may change, resulting in an inconsistency with the IP configured in the node-red node, which prevents you from accessing registered devices. It is recommended that you configure a static IP for the iHost in your router to prevent the IP address change from causing the error.
I have a cluster table which works as a virtual cube and it works fine. Recently I had to add a new attribute (navigation attribute) to it and then all the data which was on the table became unreadable, i.e., the "import from database" command started causing the exception "An exception with the type CX_SY_IMPORT_MISMATCH_ERROR occurred, but was neither handled locally, nor declared in a RAISING...". All data stored to the cluster table AFTER the new attribute could be read normally.
I checked the functions that I had created for reading and writing (import from, export to) and identified that the layout of one of the fields imported became different and that was why old data was causing issues (the layout read didn't match).
My problem is that I can't force my users to delete and reload all the data to the virtual cube, it would be too time consuming. I'd need some program or utility that could convert the old data to the new format but I don't know how to do it.
below some code for method A (excerpt w/o data definitions) - the IMPORT part might help to convert the data - just use CREATE DATA wirhount any handle but static types (old type/new type) followed by aSSIGN and IMPORT,
I'm wanting to check something before I start working on a project; Currently I'm running DrivePool with 4 drives on a Windows 10 machine. I want to convert this machine to a Linux host, install Windows 10 as a guest using VirtualBox, share my four drives to have read/write access between the host/guest machine, and then run DrivePool from within the Windows 10 guest to manage these drives. Virtualbox mounts the shared drives as network drives.
Does anyone see possible issues with using DrivePool in this way? I don't have a huge performance demand, so read/write delays are OK. I'm just more worried about DrivePool even being able to manage networked drives in this way. I enjoy the product and find it an effective alternative to what I was using RAID for. I also have to much data on these four drives to off-load and re-establish as a RAID array under Linux. So I'm trying to do a work around to allow me to continue using the program within a virtual machine, with a few other Windows only programs I can't part with.
Also, with the above example, would I need to remove the drives from my pool prior to reformatting the current Windows machine? Or would DrivePool find the data when I re-add them as a new pool, once everything is setup under the VirtualBox guest machine?
Forgot I still had VirtualBox installed on a machine. Tested this out, and I guess it's not possible. It only seems to work with local drives. Maybe CloudDrive is still an option? I'll look into it more and go from there. Thanks anyway!
I currently run a fully virtualized Stablebit Drivepool with Scanner on a Windows 7 guest running on top of a Proxmox Linux KVM Hypervisor, the hard disks are passed through to the Drivepool VM along with SMART data, it runs great with good disk and network performance and no problems for almost a month now.
Those of you that have followed this blog for a while may remember my first post where I talked about pointing a CUBE through an ASA out to my ITSP, Flowroute. That post is located here for your reading pleasure.
To that end, my replacement CUBE is virtual. Yes, I said virtual. If you follow Cisco and their products, you may already know about the Cloud Services Router, the CSR1000V. The CSR1000V is a virtual router that runs on a VMWare ESXi host. It runs IOS XE though there is some Linux/Unix on the backend that makes it tick.
When I first heard that it was possible to turn a CSR1000V into a CUBE, I was skeptical. As I have worked through the configurations and witnessed it work, I must say I am impressed. The configuration is the same as with any other IOS XE router with exception of the interface naming conventions. There are three (3) Gigabit Ethernet interfaces and they are named Gigabit Ethernet 1, Gigabit Ethernet 2 and Gigabit Ethernet 3. The configuration in ESXi is shown below.
