Hi r-people :) I'm sorry to disturb but I must admit that I know amazingly little about R and similar statistics-packages/languages and I'm kind of lost on where to start. I'm currently working on a datacollection framework for postgresql (The db doesn't really matter except that I hope to use PL/R) and I would like to be able to predict future values preferable 1 day or more

...from now", but the meaning of "now" is ambiguous, particularly if the vcpu can be preempted at any time, which means the determination of "now" can be arbitrarily deferred. However, an absolute time is only meaningful if the kernel and hypervisor are operating off the same timebase (ie, no drift). In general, the kernel's monotonic timer is going to start from 0ns when the virtual machine is booted, and the hypervisor's is going to start at 0ns when the hypervisor is booted. If they're operating off the same timebase, then in principle you can work out a constan...

Heya, Most of the windows ssh clients (putty, securecrt) have anti-idle features. They offer either a null packet or protocol no-op or user defined string to be sent over every x seconds. Is this possible or planned with the OpenSSH client? Our draconian firewall admins have started timing out ssh sessions. Yes I'm aware I could hack up a port forwarding dumb traffic process, but was

With both vorbis and libmng nearing stable status, I've been thinking about combining the two to make a real multimedia format. What would be involved in embedding mng in an ogg bitstream? From what I've read of the documentation, there doesn't seem to be any codec-enumeration system. Do we just interleave the packets and let the player guess based on the headers which codec to try? I

Hi, I am not sure, but I think this may be a process accounting bug. If interrupts are disabled for a considerable amount of time ( say multiple ticks), the process accounting code will still account a single tick for such cases, on the next interrupt tick. Shouldn't we have some way to fix that case like we do for NO_HZ restart_sched_tick case, where we account for multiple idle ticks.

...ove all these records after merging. Although I havent checked the feasibility of this method, it would be complex and more so it will increase the data four folds (I already have 2 million records in the dataframe which I have to make regular). Another approach that I could think of was to make a timebased sequence based on the date from the file and then use a loop to append one sequence after another. But am not having much success there either. Any kind of help would be greatly appreciated. Thanks and regards, Shivam structure(list("20110103", "20110104", "20110105&quo...

...bundant R references (tutorials, wiki, etc.), but I was hoping to find pointers here to help me become productive sooner rather than later. Here's my present brute-force plan of attack: - Load both data sets (in CSV format). Each data element is a timestamp + 3-axis acceleration. - Determine timebase offset: The unit clocks don't match perfectly, and the units were started at slightly different times, so I expect to correlate common events in the data. - Find all overlapping data clusters (between superset of gaps). - See if I have enough data to perform spectral analysis. I'd like to...
