  1. Views, Materialized views? on Why Reactive Programming For Databases Is Awesome · · Score: 1

    The idea of embedding a calculation into the system that is automatically updated by underlying data changes -- is that not just a database view?

    We use this sort of technique quite widely in a Ruby on Rails app I work on -- complex calculations such as for profitability and cash flow are defined as views in Postgres, and referenced by the app as read-only models. Thus we can: Profitability.where(product_id: 27).group(:month).sum(:value)

    Performs monstrously fast, as is extremely flexible. It breaks the whole "for the love of gods don't put business logic in the database" separation of concerns idea, but we have a system to ship right now and we can't wait for RoR performance and flexibility to catch-up that much.

    "25 Mega Tons of fire" is an interesting way of quantifying the energy in something less than 600,000 tons of LNG. Considering your estimate of 5 or 10 million deaths, along with overuse of exclamation marks, I think that you might be a little bit unbalanced.

  3. Not an issue ... on Project Free TV, YIFY, PrimeWire Blocked In the UK · · Score: 2

    Because only a trivially small proportion of the population cares. Few have even heard about these services.

    If you care about free TV in the UK then you could start by not watching or recording live transmissions, and you then have no obligation to pay the TV license -- they only waste it on extra redundancy payments for senior managers, and politically motivated nonsense stuff like moving programming oop north.

    I get by on BBC iPlayer delayed transmissions, streaming to my TV through Chromecast. Possibly ITV and Channel 4 have compatible streaming services, but sadly their programmes are not compatible with me.

  4. Right in a kind-of way. on The Luddites Are Almost Always Wrong: Why Tech Doesn't Kill Jobs · · Score: 1

    At the last company where I worked, word processors and voice mail systems allowed them to have zero secretaries and receptionists, as software developers had to answer the door phone and type their own everythings. Of course this did double the number of software developers they needed because they all got fuck all work done, so I guess the article's correct.

  7. Re:Who cares what the community thinks? on Ask Slashdot: Does Your Work Schedule Make You Unproductive? · · Score: 2

    That is all true, but the days of "scientific management" are over, and research does not matter.

    Managers believe that you achieve efficiency and greatness through gut feeling and tough talk and catchy slogans. They are not interested in learning otherwise, and 90% of them were never taught management, they just got promoted into it.

    There are a few companies that will make sensible, evidence-based choices, but the only true fix is to work for yourself.

    I think that your response illustrates a very different approach and purpose -- in the US the computerised record is for billing, but in the UK the computerised record could simply be a description of symptoms and treatments.

    There's no need for the UK to follow the medicine-as-a-profit-centre approach of the US.

  11. Re:Clinical records are hard on Abandoned UK National Health Service IT System Has Cost $16bn... So Far · · Score: 2

    Speaking as a dyed-in-the-wool data modeller and corporate database guy, I wonder what the problem would be with throwing all of that data modeling and medical coding stuff away and just letting people write into the system what actually happened, exactly as they do with paper records. Some tagging for "this was a procedure" or "this was a test", but free text the rest of the way.

    At least the information would then be accessible through a computer to far-flung locations (Norwich) in case it was needed there, it wouldn't be in some doctors squashed-spider scrawl, and it would be ultimately flexible. Of course it would not be as amenable to analysis and reporting, but it would be something.

    Is this failure just the result of seeking a gold-plated solution?

    I was a green card holder living in the US for ten years as the spouse of a USAF officer, and you're absolutely right about the immigration people.

    My co-workers didn't believe that things were as bad as I said, until I spent a day trying to call the INS in Cincinnati on speaker phone. Nine hours of listening to a recorded message telling me that I was in a queue. I had to take the next morning off to drive down there from Dayton to wait in their office for 75 minutes in order to get a 10 second question answered.

    Amusingly, they gave me a different answer to the consulate in Rome a couple of months later, so I ended up paying about $200 for some documents to be replaced there, and when I returned to the US at the end of that vacation I had to wait for two hours in immigration because both the Cincinnati office and Rome consulate gave me the wrong answers.

    I'm done with the US -- never going back.

  15. Re:Catastrophically awful idea on Bill Gates Seeking Patent To Make Shakespeare Less Boring · · Score: 1

    I completely agree, but the point of the patent is not to do something more effectively, or in any way better, but to protect your idea so that you can make money from it.

    I guess that people stopped making money from printing unadorned works of Shakespeare quite some time ago, and have to find new ways of doing so. This just appears to be a way of linking existing OCR technology with book lookup and thence to multimedia -- none of them innovative, but the combination being a potential money maker.

    It's quite common to only accept submissions electronically, and it really takes only a second or two to delete them. A spell checker would be interesting but would trip up over books with a lot of dialect in them.

    Ah, but you're missing some crucial points -- that the primary role of a publisher is to actually make money, and that the most effective way to avoid losing money in publishing is to shutdown immediately and never publish another book.

  19. Re:A practical algorithm for manuscript quality. on J.K. Rowling Should Try the Voting Algorithm · · Score: 1

    Celebrities get ghost writers to at-the-very-least correct their spelling etc, because the cost is covered by the guaranteed sales into the hands of the mouth-breathing hordes. It's not an expense worth going to for a book that is a gamble for the publisher.

  20. The pleasure of the crowd on J.K. Rowling Should Try the Voting Algorithm · · Score: 0

    My own theory about the stellar popularity of particular authors is that many people just want to share the experience of reading, just as they want to share the experience of watching American Idol or Strictly Come Dancing.

    A book that everyone is reading is also a social event, and there's maybe social pressures to read it also.

    It's really the only explanation I can think of for the popularity of a book about a teenage wizard in the over-20's demographics.

  21. A practical algorithm for manuscript quality. on J.K. Rowling Should Try the Voting Algorithm · · Score: 5, Funny

    Speaking as someone who shares a sofa of an evening with a publisher, I can vouch that almost every manuscript submitted to any publisher will be dreadful in almost every single department. It starts with embarrassingly poor spelling and punctuation, and moves on through dreadful grammar, choice of paragraph size, layout, and on to issues with plot, characterisation, and general readability.

    The average quality hovers somewhere between execrable and toe-curlingly awful, and they get dismissed after a glance through the first page. Sometimes the covering letter is enough and the manuscript can be spared its cursory eyeballing, because if you cannot correctly spell and punctuate in your covering letter then you're wasting everyone's time -- thankfully only 15 seconds of it was the publishers, and two years of it was yours.

    Based on that alone, a very useful algorithm with a high degree of accuracy in judging a manuscript's quality is to just throw it straight in the bin -- you'd only be wrong one time in a couple of hundred, which is a pretty good average.

    Yes, deliberate flooding was recognised at the time as a solution for accidental flooding problems.

    Taking the famous Andrea Doria collision with the Stockholm, there was an attempt to flood empty tanks on the former in order to right the list caused by flooding that followed from severe collision damage. To no avail, however.
