Comment Why not use VNC? (Score 1) 302

I've not seen any mention of this, but why not "VNC" to share a desktop?

I've used it frequently with distant co-workers to collaborate on why their environment is causing program breakage. Especially when I cannot duplicate the failure in my environment.

VNC allows "full access" as well as "read-only access" so you can control whether your classmate can access your stuff.

Alternatives to Daylight Saving Time? 755

Wellington Grey writes "Daylight saving time almost upon us. The arguments about its possible benefits and drawbacks come up twice every year. Does it save energy or lives? Possibly, but it does definitely cause a great deal of inconvenience. My question is this: what do you think would be the best possible system to replace DST with? What is the best way for humans to deal with the inconsistent amount of light over the year and still foster coordination over disparate time zones?"

Comment Profiling? (Score 4, Informative) 54

I'm no network / data access guru, but this seems like a typical case of profile first, optimize later.

The idea is simple. Don't just go in and change stuff, first measure the pieces under typical load. Look where the bottle-neck is, address it, and move to the next bottle-neck. Repeat as often as needed.

Are you disk I/O bound? Buy faster disk / better controllers / spread the load over more machines / .....

Are you CPU bound? Is the CPU on your server spending so much time with I/O requests, that it has no cycles available to address additional requests? Buy more / faster / better CPUs.

Are you network bound? Which piece of the network is the hold-up? Your switch? Get a better / faster one. Your ISP? Get a fatter pipe.

Have you optimized all of these? What about setting up remote servers that are updated hourly/daily/weekly/whatever so the machine is close to the user network-wise for faster download speeds.

Some of the above adds complexity. Are you equipped to handle that complexity? Can you become equipped to handle it? If not, re-consider your options.

Hope this helps.

Cheers,
Dave
