Dishwasha writes "What do you do to stay fit? Probably like many of you, this code monkey has lead a fairly sedentary life consisting most on fritos, tab, and mountain dew. Every time I attempt to incorporate exercise in even the most modest amount it never really seems to work out. "Just do it" or joining and going to a gym just doesn't seem to work and with time being my most precious resource at this point, I would like to incorporate exercise in to my daily work process. Our office recently switched to standing desks, which is great, and I would like to possibly bring in a flat treadmill that fits under the standing desk, but my bosses have balked unless the equipment is whisper silent. We are a small business in a traditional office park with no exercise facility. Do any other geeks out there have a similar set up and would like to share what they use to stay heart healthy and improve circulation during their work day? What other ways do you incorporate exercise in to your geeky or nerdy lifestyle?" top

Does anybody have any recommendations for a gamer quality wireless keyboard? Can anybody also recommend a gamer quality wireless keyboard with good range (I would like it to work 8-10 feet away from the transceiver? Feel free to throw in mice recommendations as well since some day I will have to upgrade from my good old Logitech G7." top
Dishwasha writes "After reading about the possibility of an earth-link planet "only" 12 light years away, I instantly thought about the possibility of sending an amateur micro satellite. Although such a thing would not reach 12 light years in my lifetime, perhaps the satellite would be a legacy that I could hand over to my children and they to their children, etc. From my perspective, the sooner we start sending out probes in to the universe and the more we send out, the earlier the start we get in exploring the universe beyond just our singular earth perspective.
A fellow co-worker of mine turned me on to the CubeSat standard and apparently there are commercial space companies that will launch CubeSat systems from their payload for a modest fee.
Is anybody in the/. community involved in amateur micro satellite systems? How would I go about getting involved at an amateur level? Are there any amateur user groups and meetups I can join? I have limited background in all the prerequisites but am eager to learn even if it takes a lifetime. Any links to design and engineering of satellites would be appreciated." top
Dishwasha writes "A bit belated, but the long awaited GlusterFS 3.3 has been released. GlusterFS is an open source, fully distributed storage solution for the world’s ever-increasing volume of unstructured data. It is a software-only, highly available, scale-out, centrally managed storage pool that can work with POSIX filesystems that support extended attributes, such as Ext3/4, XFS, BTRFS and many more.
Major features also quoted from the website: * Unified File and Object storage – Blending OpenStack’s Object Storage API with GlusterFS provides simultaneous read and write access to data as files or as objects. * HDFS compatibility – Gives Hadoop administrators the ability to run MapReduce jobs on unstructured data on GlusterFS and access the data with well-known tools and shell scripts. * Proactive self-healing – GlusterFS volumes will now automatically restore file integrity after a replica recovers from failure. * Granular locking – Allows large files to be accessed even during self-healing, a feature that is particularly important for VM images. * Replication improvements – With quorum enforcement you can be confident that your data has been written in at least the configured number of places before the file operation returns, allowing a user-configurable adjustment to fault tolerance vs performance."

I recently purchased a brand new laptop for my wife and it has had the same intermittent problem from the beginning. We just received it back from its second repair and in both cases the RMA department performed up to a 24-hour "burn-in" test, declared there was no problem and sent it back even though I specified that the intermittent problem can take up to a week to reproduce. I explicitly asked for the problem part to be replaced for the second RMA and they completely ignored my demand. They have also refused to send me the part so I can repair it myself. I have asked to have this escalated to a manager but have been told they MIGHT call me back and refuse to follow my instructions in favor of their own inadequate troubleshooting steps. At this point I am tired of having my time taken up with this and believe it is unfair to my wife to have her relatively brand new laptop sent off for 2+ weeks at a time.
I am in Texas and understand that each state may have specific laws and procedures for declaring a lemon. I've goggled for Texas Lemon Law and came up with this informative article. It mentions "Texas Lemon Laws... provide for compensation to Texas consumers of defective automobiles... and products including... computers and other consumer appliances and products" yet the rest of the information seems primarily tailored to motor vehicles. If the rules are the same I would qualify for the 30-day test depending on the interpretation of "a substantial problem". If not, I guess I will have to give them two more chances for repair which puts my wife out another month at a minimum without her laptop.
I will attempt to research the legislation myself, but would welcome any constructive tips on making sure all the correct bureaucratic things are done to minimize delays. I would also be interested in hearing of any success stories regarding declaring a computer a lemon and getting the manufacturer to reconcile fiscally." top
Dishwasha writes "For over a decade I have had arrays of 10-20 disks providing larger than normal storage at home. I have suffered twice through complete loss of data once due to accidentally not re-enabling the notification on my hardware RAID and having an array power supply fail and the RAID controller was unable to recover half of the entire array. Now, I run RAID-10 manually verifying that each mirrored pair is properly distributed across each enclosure. I would like to upgrade the hardware but am currently severely tied to the current RAID hardware and would like to take a more hardware agnostic approach by utilizing a cluster filesystem. I currently have 8TB of data (16TB raw storage) and am very paranoid about data loss.
Lustre is well accepted and used in 7 of the top 10 supercomputers in the world, but it has been sullied by the buy-off of Sun to Oracle. Fortunately the creator seems to have Lustre back under control via his company Whamcloud, but I am still reticent to pick something once affiliated with Oracle and it also appears that the solution may be a bit more complex than I need. Right now I would like to reduce my hardware requirements to 2 servers total with an equal number of disks to serve as both filesystem cluster servers and KVM hosts.
GlusterFS seems to be gaining a lot of momentum now having backing from Red Hat. It is much less complex and supports distributed replication and directly exporting volumes through CIFS, but doesn't quite have the same endorsement as Lustre.
Ceph seems the smallest of the three projects, but has an interesting striping and replication block-level driver called Rados.
I really would like a clustered filesystem with distributed, replicated, and striped capabilities. If possible, I would like to control the number of replications at a file level. The cluster filesystem should work well with hosting virtual machines in a high-available fashion thereby supporting guest migrations. And lastly it should require as minimal hardware as possible with the possibility of upgrading and scaling without taking down data.
Has anybody here on Slashdot had any experience with one or more of these clustered file systems? Are there any bandwidth and/or latency comparisons between them? Has anyone experienced a failure and can share their experience with the ease of recovery? Does anyone have any recommendations and why?" top

Dishwasha writes "There seems to be a lot of chatter about NAS and SAN storage and there is a lot of consensus on using FreeNAS or OpenFiler, a multi-drive controller, and a redundant RAID level, but what insight does the/. community have on providing greater live redundancy than just the disks and power supplies? Using RAID-10, you can effectively stripe across controllers for controller redundancy, but is there any redundant controller solutions for RAID-5/6 without doing RAID-51/61 (RAID-5 hardware, RAID-1 software) and duplicating a lot of disks? More enterprise-level equipment has two data paths to the physical drives themselves as well as redundant storage processors, is there anything like this available on the open market? How about platform? The AMD Opteron platform allows for dedicated RAM per-processor, but is there any hardware or software that will safely migrate process-0 to a second processor and keep the system operational? The Linux Hotplug CPU project seems to be accomplishing this; has anyone safely used this on an x86/x64 platform? What hardware did you use and were you able to achieve full redundancy during a processor failure?" top
Dishwasha writes "The capabilities offered by The iSCSI Enterprise Target Project and LVM2 really make commodity SAN solutions for clustering or remote raw storage a possibility. iSCSI or Fiberchannel SAN equipment has typically been very expensive and most of the lower cost equipment has minimal expansion flexibility that you would typically get from a high dollar EMC solution. I see one of the bars to entry is hardware redundancy not at the disk level, but at the processing level. Even the lower end Dell/EMC CX3 and AX100/150 solutions have redundant storage processors and in some cases, backplane redundancy to the disks. Is there any commodity i386/x64 hardware out there that provides CPU redundancy rather than just multi-processing? If so, does anybody have any experience using this with Linux Hotplug CPU Support? At least some of the commercial hardware SAN solutions require a full outage for service on a storage processor, but allowing for hot CPU, RAM, backplane, and controller would definately be a plus if anyone has any experience with getting these components redundant on the i386/x64 platform." top
Dishwasha writes "I have several customers that have recently received a notice from the Broadcast Music Incorporated (BMI) that they were in violation of the music rights which BMI owns. They were sited that they had "Music on Hold; TVs in Public Waiting Rooms, in Therapy Sessions, In Fitness Centers, in Operating Rooms, and in Patient Rooms." Apparently none of these applied except for having a TV in waiting rooms and patient rooms. BMI is demanding my customers to sign an agreement for a "Health Care Multiple Use License". More recently one of my customers is a hospital in a town consisting of a population of less than 800 and they have been directly invoiced by the BMI for the use of TVs in public waiting areas.
Is there any legal advice, articles, or documentation the community can offer me that I can share with my customers? Does BMI hold any legal right to claim fees on publicly broadcasted material that is receiving royalties through advertisement that is not being charged by the accused to their customers nor directly generating any revenue or profit, but is simply accessed via a common device used to gain access to public services (i.e. Broadcasted Television) and not being duplicated in any illegal fashion?"
