Don't get me wrong. I am really interested in seeing both lunar and asteroid exploration.

Criswell estimates that the 10 billion people living on Earth in 2050 will require 20 Terrawatts (TW) of power. The Moon receives 13,000 TW of power from the sun. Criswell suggests that harnessing just 1% of the solar power and directing it toward Earth could replace fossil fuel power plants on Earth. This idea has been around for quite a while. It is fun to daydream of what we could do with inexhaustible clean energy. Not like petroleum companies are going to let that happen...
>>Alfresco is an open source content management system like SugarCRM. I haven't used alfresco but would argue that there is a sizeable difference between cms and crm.
>>Does anyone know of other similar open source projects? http://www.cmsmatrix.org/ is a decent place to start
Ah, my sincere apologies. You are correct.
I'm a bit embarrassed:). I confused that with another company I was reviewing around that same time period. Their name escapes me...but I will find out. (I'd hate to say the wrong company)
thanks for the correction
I'm not that well versed in this stuff so make sure to do your own research. (the disclaimer is now out of the way).
You can't compare zfs to SAN. I didn't need a san but look at nas. Netapp is great but still had a few limitations.
The discs were proprietary.
redundancy. To go with the redundant head was to bump up to a new level in cost.
chassis size was set
the cost ran up fast for the software to do the things I wanted. all proprietary (which was alright considering)
Still, netapp is quite a quality product.
I wanted a cheaper solution that had more to it so I looked at coraid.
They use an AoE (ata over ethernet) protocol that is lighter than tcp/ip.
It can run with off-the-shelf sata drives
a gateway can be used if you want to add more shelves
they have redundant gateway solution as well
We'll be putting it in this quarter.
Having said this, I'm unsure of the state of lvm2 for block level snapshots. This was one thing that netapp did well. Also, be selective on the drives you choose. This is only another option you can look into.
My history is java but I've come to appreciate php recently. The track record on it when used properly is impressive. In case there are some people just starting with it, the several of the problems with php performance is caching. (this is pretty standard stuff so apoligies to people who know a lot more about it than I do)
Use apc or eaccelerator. (yahoo uses apc so that is the one we went with). This alone will give considerable benefit.
Apc can defaultly cache any of the php that runs or it can also be used as a local cache for objects you'd like to store programmatically.
If you need distributed items, especially in a non-sticky load balanced environment, look at memcached.
Use a query cache for your db
If your db connections are expensive, look at sqlrelay
Look at whether a caching proxy is a possibility for you (squid or apache has some mods).
Benchmark your pages and functions. It is the only way to know if configuration tweaks are adding any value. I usually do this after a full profiling using apd (to help identify the bottlenecks and frequently called functions). I usually run apache's ab to get a look at page benchmarks.
you can always write c extensions for items in php that are too slow. Of course, you'll have to know c, increased maintenance, development time, etc
There are a million things to be done to increase performance. Obviously, don't use anything blindly. Still, I think the opcode cache (apc or eAccelerator) is probably the easiest and most substantial win.
if it is a general statment, agreed. Nobody likes a bitch/he-bitch.:)
if i am the whiny bitch then i would have thought your sympathetic post for the star wars kid http://yro.slashdot.org/yro/06/04/07/1523237.shtml would apply to the environment which some women are forced to work or leave IT
I like a good joke as much as the next guy. I'm assuming that 95% of the people that come to this board are male. But I could see why a woman might feel a bit out of place just by the reaction to this poorly formed "study"
If you read the board, you'll see why.
I mean, damn. Most of the posts read like they are out of a steelworkers union after-bar party.
...and to think I argued with someone last week in defense of IT. "nooo..guys in technology aren't misogynistic"
yeah. completely trolling. What got me a little miffed was this statement
The users want to have better and cheaper options but don't really want to bet their future on open source (unless they are universities or nonprofits and that is the best they can do).
This statement would lead you to believe that open source = shoddy software. (and also that nonprofit is second class technology..but that's a different subject)
We are a nonprofit. We aren't really large or anything but we'll be hitting 100 million views/month by year's end. We have been in a fortunate position where we could purchase almost any software we require. The vast majority of the proprietary software that we could use, we could get for a nominal fee from techsoup.
We chose open source not because we couldn't do better but because it was better.
I'd talk to some friends that know you and inquire about their careers.
I've had a friend in exactly this situation. I pointed him to http://vocationvacations.com/. Now he owns a coffee shop and sells cheesecake.
Also, I'd consider going back to school. Reading through the class offerings was a really good way to find what I had interest in.
The reality is, unless you are ready for a decrease in pay, moving completely out of the field (any field you've been in long term) is difficult. With all your experience, you might consider consulting. At least that way you have a little more choice in the projects you take.
I'm in a similar boat but less experience than you have. It is a very consuming and confusing process. But until I figure it out, I'll continue to scour hotjobs for "pasty fitting technician":)
ah..bullshit. It isn't about "corps vs little guys". I'm at a small (though high traffic) non-profit and we had numerous squatters. We still have a few.
Basically, they try to appear to serve a similar function as we do. Click on something, you are blasted with ads/popups.
Purchasing all these extra domains was a sizeable fee for us. The reality is we are the little guy and the squatter is an established and wealthy corp. Viva la "cease and desist you cybersquat bastard"
I've been telecommuting for 7 years or more. I love what I do and have great perks with a great company.
The only real negative is not so much that advancement at the company isn't available as much as networking with others outside of it. Face time with coworkers normally leads to the beneficial effect of meeting their contacts/friends/past coworkers. Having moved to another location, not having a solid network of other professionals at local companies has made it difficult to consider leaving the remote company.
that and my social skills have suffered:)
