  1. Re:Home mitigation? on No More Foamy Beer, Thanks To Magnets · · Score: 5, Informative

    Carbon dioxide solubility decreases with increasing temperature (dissociation constant of water increases, and the extra hydrogen ions push out the carbon dioxide molecules, in addition to gaseous solubilty decreasing with increasing temperature because the energy of the CO2 molecule exceeds the solvation energy), so if your downstairs fridge is warmer, the foam will come out more. Things you can do:
    -Chill the beer more.
    -Cool the outside of the glass with cold tap water.
    -Pour a slow stream of beer down the side of the glass (not directly to the bottom). This chills the path of the beer and you are less likely to foam. If you pour directly to the bottom, it'll just push out.

    Good luck. Remember RDWHAHB (Relax, Don't Worry, Have A Home Brew).

    They did tell us, but not how. In their FAQ, they said they built an algorithm. What is it? I don't know. Undoubtedly it relates to favorite/retweet frequencies, but I'm sure it's more complex than highest retweet count.

  3. Re:My first Bennett post. on An Algorithm To Prevent Twitter Hashtag Degeneration · · Score: 2

    What you're proposing is trivial, looking at the relative ratios. As you don't work for Twitter, I would expect that you are not privy to their algorithm. Look more closely at top tweets, they are not only selected by follower favorites or retweet. Any egghead (I say that with fondness, not in a pejorative fashion) on this board would notice that. Your post (while written with good grammar and spelling) required two pages to not notice that. You provide conjecture without rigorous analysis.

    I don't really care whether you post or not, but I do wonder why /. gives so much front page space to someone who effectively considers the lilies.

  4. My first Bennett post. on An Algorithm To Prevent Twitter Hashtag Degeneration · · Score: 5, Informative

    My first post to a Bennett post:

    Quoting Bennett:
    (The simpler and more obvious solution would be to display tweets as "highest rated" if they had been favorited or retweeted by lots of people. However, this is problematic because it allows a person to game the system by having all of their friends -- or sockpuppet accounts -- "like" a tweet in order to drive it to the top of the pile. By having the ratings come from a random subset of users, this resists attempts to game the system, because there's no way for a user to ensure that their friends will be among the random subset that is selected to rate the tweet.)
    End Quoting Bennett:

    Bennett, perhaps if you were to click a trending hashtag, you would see that they list either 'Top Tweets' or 'All,' and you would note that those that were retweeted or favorited would be on the Top Tweet list, just like your recommendation. Except this has been there for years.

    My god, it must be a thousand words to point out existing functionality of an inanely simple concept that has already been executed. I now see what the hullabaloo is all about.

    Agreed, I was talking specifically about programmers, although the previous post did say the tech industry so I should have been more clear on that.

    All people accepting corporate positions will know if they are exempt or non-exempt, and as you said that classification is determined by their job duties. If a corporation does force overtime without pay they are opening themselves up to risk they normally wouldn't accept.

    Now for start-ups, they play faster and looser, and usually get people to work overtime whether they are exempt or not.

  7. Re:No on Should IT Professionals Be Exempt From Overtime Regulations? · · Score: 2

    For programmers in CA, normally they are non-exempt, although I'm sure many skirt around it. My understanding is if you want a favorable equity package, you'll accept exempt status. If you want an hourly wage and a life, you declare non-exempt. .

    Personally, I think if you're not a manager and you aren't getting a good chunk of stock, you should be getting overtime.

  10. Re:Sounds more like technical short-sightedness on Apple Accused of Deleting Songs From iPods Without Users' Knowledge · · Score: 1

    This is one of the better descriptions of how it works, well done. There are apps that allow a sync back from the iPod to the iTunes library, but I've never tried them.

    My challenges are that I have much more music in my library from CDs etc than I do for my iPods/iPhones, so I can't auto-sync (they have a 'Sync until full' feature now, but I'm not bothering with that on my phone), so I'm stuck with manually syncing them. Then when they have an iTunes update, or if I use a new device, I have to click two buttons, Manual Sync, and then Enable Manual sync (I think, I"m not at home). Then you have to go through and manual check the genre, album, artist, or playlists...and I still have a couple of songs that I'm not licensed for (which may be one of these pirated DRM files).

    Then, as I use Sonos at home, everytime they update iTunes they move the Library location and I have to re-index the Sonos controller library, and don't get me started on the Sonos Controller not having a simple interface to the soundcard...

    I do like Apple products, but it's tough for the egghead in me to not long for the simple copy/paste operations on the disk drives.

    Non-profit corporations are not allowed to give equity to their employees, and that automatically keeps them at a compensation level below private corporations. If you want talent that can sustain the number 6 site in the world, you'll need to hire them where they are (in CA) and pay them commensurate to the industry practices.

    $200,000 is not a lot for an Executive Director, and $100K is needed for a 'good' programmer here.

    You can suggest that they move, but why? There is infrastructure and access to local contractors that you wouldn't have anywhere else.

    It won't take you too long to learn how to write crappy code in either language. What you really need is a place to work that has focused goals, a clear set of programming guidelines that are built around writing code that others can read later, and the sitzfleisch to do the work.

    Find a job with a boss who is passionate about his/her work and are demanding enough to make you want to do a good job. There is no quick rich scheme in the next couple of months, programming quality apps is about art as well as science, and both take a lot of effort.

Netflix now has profiles which may eventually help, but for now the ancient creaking machine of Nielsen still determines how a company's advertising dollar is spent.

  17. Re:Hydrogen is a nice alternative on Toyota Names Upcoming Hydrogen Fuel Cell Car · · Score: 1

    One of the primary issues I see is separation costs and poor energy efficiency. With gas (petrol on the other side of the pond), energy is expended to boil a bunch of oil and filter out the primarily six-seven-eight carbon molecules at about 350 kJ/kg, which is easily stored and distributed in liquid form to yield about 42,000 kJ/kg upon combustion. That's a nice 100:1 energy produced/separation energy without any need for compression. Obviously more energy is needed to procure the oil, pre-process it, etc.

    So look at hydrogen. Rough numbers are to electrolyze 1 kilogram water to hydrogen and oxygen is about 13,000 kJ/kg of water, and the energy yield is about 16,000 kJ/kg, or about 1:1 energy produced/energy to separate, and that's not including purifying the water before electrolysis, separating the hydrogen (assuming a membrane separation), compressing it, and then using it.

    This leads to using hydrogen only from natural gas, and then I'm not sure what problem we are solving if we are trying to eliminate carbon.
