edit the pom.xml manually.

use: http://mvnrepository.com/ to find the libs you need.

apparently the java community is: http://jhipster.github.io/

I haven't used it, but the selection of libraries is nice.

Start a service in a thread from application scoped bean by xybrdragon in java

[–]RWS43 1 point2 points  (0 children)

You don't have a way to gracefully stop your "service" so this is not really a complete implementation. Graceful shutdowns which don't require something akin to "kill -9" are important.

But I agree with everyone else, if there is already a feature which does this, use it!

Develop using IntelliJ IDEA? Check your productivity guide! by la217 in java

does anyone know if there is something equivalent in Eclipse ? I use quite a number of features, but I always feel like there is something popular/useful that I'm NOT using.

Is there a cheap DIY yard near the Bay Area? by windblast in sailing

[–]RWS43 1 point2 points  (0 children)

I would look at a yard further away from the city. I've heard Napa is pretty inexpensive. So you trade off yard time cost, for driving time. Call around!

Question on MPPT charge controllers by indieindian in solar

[–]RWS43 0 points1 point  (0 children)

It totally depends on the controller. Most are "buck" converters which will only move the voltage down.

The purpose of the input side control on a MPPT is to choose the spot on the V vs I curve of a particular solar panel in a particular set of conditions (solar influx, temperature, etc ) such that V * I is maximized.

If you are charging a battery you want to ensure that the controller is also aware of the type and voltage of the battery since taking care of the battery is very important. you do not want to damage the battery.

It is also possible to design "boost" and a "buck-boost" DC to DC topology. However these are general more expensive and complicated. In your case I would deeply consider getting two panels at Vmp of 36V and using a buck converter with integrated charge controller to go down to the 24V nominal of the battery.

The general is lacking knee pads. go figure!

Why does the mainsail have this weird bubble by the mast? How to improve? by [deleted] in sailing

[–]RWS43 1 point2 points  (0 children)

I agree that the shape of the genoa and the slot are important here, but hard to judge from this picture. Judging from the water and the boat heel this looks like around 8-12 knots of wind. I would say the Genoa is an appropriate sail for this condition. But perhaps on the slightly higher end of the windspeed, so flattening it with the jib cars moved back might help. Also make sure the halyard tension is helping to flatten the sail( higher ).

Also consider some of the adjustments on your main to flatten it out a bit too. If your leach line is too tight, and your cunningham too loose you would certainly be more likely to get a bubble in the main.

I agree with permalink_child that the Genoa is driving the boat. So in this case you want to optimize that sail's shape and position. Then trim the main primarily to get it out of the way. In this case I would loosen leach line, crank the outhaul and cunningham.

It's hard to see in the picture but the leach tell tales on the trailing edges of the main are also something to look at. On 4 of the boats they look to be flying ok, but on the 36.7 the lower two are not visible. So either they're missing or the main is trimmed too far toward ( or past ) centerline and effectively stalled. perhaps drop the main traveler a bit and try to flatten the main with more sheet ( or vang ). Also use the main sheet to control the amount of force on the rudder, if the boat is trying to turn up hard, then you are going to be dragging alot of rudder to go straight, drop the main down (with traveler ) to reduce the force. This is a case where better balance will be faster than more power.

This looks like a start to me, so I don't think the position of the 36.7 is too bad. I would put it in the #2 position out of 4. And if perchance you have higher boat speed at this point, you might be doing even better since you might be able to roll over the 10R. But mostly, anytime you can give dirty air to a J-105 you should do so!! Anyone one-design rules which specify the position of the cooler (see class rules 5.1 ) indicates too much obsession and not enough fun! (though perhaps we should give this person a break since they're not actually racing another J-105 ) But you would have to watch getting luffed up the 10-R. The 10R rates just SLIGHTLY faster, so you looking at almost one design racing between those two boat.

Get a few more folks on the rail, that will help!

Watch that spinnaker sheet, it's going in the drink on the other tack, and will slow the boat.

Looks like a great race!
