  1. Re:Why processes instead of threads? on Firefox 54 Arrives With Multi-Process Support For All Users (venturebeat.com) · · Score: 5, Informative

    They explain it pretty thoroughly in their Medium post about Firefox 54.

    It's mainly about using less memory. The maximum number of processes is configurable (about:config dom.ipc.processCount) and defaults to 4. During extensive testing, four processes gave the best combination of speed and memory utilization. Memory utilization was quite a bit lower than Chrome (Chrome used anywhere from 36-77% more RAM).

    The first four tabs you open spin off individual processes and then new tabs are attached to existing processes (they don't say how this is done - round-robin or some sort of load balancer).

    Four processes is supposed to be the best for systems that have 8G of RAM or less. If you have more, you can bump up the processCount.

    "Mozilla should be spending 100% of its time working on its browser! Why are they wasting time doing anything other than rolling back the GUI to the one in Firefox 4.0? I hate the new Chrome look so damned much I switched to Chrome and never looked back."

  3. Canada did the exact same thing (privatize to an NGO) in 1996.

    Nav Canada, the NGO that operates Canada's air traffic control, has won three IATA Eagle Awards for Best Air Traffic Controller since 2001. It also closely coordinates with the existing FAA ATC system as the Canadian and US airspace are extremely interrelated (perhaps the most so in the world).

    Canada is one of about 50 countries that have gone this route (Britain, Germany, Australia and New Zealand are among the countries that have done so). Nav Canada even sells their system (Australia runs on it) - we could potentially just buy a solution.

    The patent isn't for a wrapped display (Samsung has had those for years) but for a wrapped touch area on such a display. My understanding is that Samsung and others do not have sensors on every portion that can light up (the wrapped portion and part of the edge has no sensor), while the Apple patent is for touchability even along the edges and wrapped area.

    The patent is about having a bezel-less edge-to-edge wrapped touch display. My understanding is that Samsung still has a bezel in the sense the the wrapped portion of the display (and a small amount near the edges) has no touch sensors.

    This isn't a patent for a wrapped display area - it's for a wrapped touch area.

    You need about 50 nuclear reactors the size of Sizewell B (1.2 GWe) to get to 1/6th of the current net energy use of the UK. We're not talking about just electricity but replacing all hydrocarbons (fuel for transport and industry, embedded energy from imports). MacKay actually assumed some fairly significant efficiency gains from electrification and technological advances, enough so that those 50 plants might handle a full third.

    Possibly because most solar / wind advocates (which I am all for) hand wave away the scope problems. Solar and wind are extremely energy diffuse - you need a lot of land to gather the amount of energy of even a modest coal or gas plant.

    I'm a big fan of David MacKay's (RIP) work - Without the Hot Air. He, like me, wanted to move to a decarbonized energy economy but he worked out the hard numbers and showed the magnitude of the scope involved. Just to get to 1/6th of the current consumption of UK energy, you need wind farms covering the entirety of Wales - every square foot would need to be within a few hundred meters of a wind mill.

    He advocated large-scale energy efficiency measures to try to drive down that amount, but even dropping the UK energy consumption in half (which is already nearly half of the US per capita) still results in a Wales sized wind farm supplying only a third of the power required. Solar within the UK was basically a non-starter in terms of total impact, but if you created a solar farm twice the size of Greater London in the Sahara, you could get another third. Add another 50 of the largest possible nuclear plants and you reach your no-carbon goal.

    But all of this assumes enormous efficiency gains. If the efficiency stays about the same, double those numbers. Technology has gotten somewhat better since he died, but not enough to significantly change the numbers.

  12. Re:Preparing for a WebExtensions disaster in FF 57 on Mozilla Kills Firefox Aurora Channel, Builds Will Move Directly From Nightly To Beta (venturebeat.com) · · Score: 3, Interesting

    I love the concern trolling that comes out with every piece of Firefox news. Mozilla has obviously lost the mainstream browser war but a lot of that is due to the fact that Google has deeper pockets and chose a base (WebKit) that was in better shape than the older Gecko was.

    People still rage about Australis but then go on and say they switched to Chrome over it, while simultaneously complaining that Australis was a Chrome clone. Now, people will leave Firefox due to WebExtensions, which is... what Chrome uses. But the Firefox WebExtensions are extended (ExtendedWebExtensions?) to provide more of the functionality of the old extension system within a more modern API.

    And the move to WebExtensions is largely due to the fact that the old extension model would be broken by the multi-process changes that have been taking place. Lack of multi-process tabs being one of the main points previously brought up by all the "Firefox sucks, move to Chrome" apologists.

    The extensions API was going to break anyway as soon as multi-process was fully implemented. Mozilla made the decision to move to an extended WebExtensions API as a nod to the fact that many extension developers are familiar with it from porting to Chrome. But the Firefox version of the API will have abilities that Chrome does not have.

    Firefox is still the only major browser that even nods the head toward respecting your privacy and the open web. It's still a perfectly good browser - it's my primary browser and I really don't have any issues with it aside from an occasional extension conflict. It's weird that so many people reflexively shit on it.

  13. Eh... I made two math errors - that's 6 states that "flip", not 5, and while you gave the total as 24 states, ECS counts Washington twice, so it's only 23.

    Plus, Ed Rendell was governor of Pennsylvania in 2004 when they passed their municipal broadband amendments.

    So, you've now got 7 additional states that were at least partially controlled by Democrats from the ECS list. Add California, Colorado, Minnesota, Nevada, Washington, and Virginia and you get 13 out of 23. Virginia has flipped around a lot and it's hard to determine the exact date of the relevant amendment (the text has been amended basically every two years) so we can call that one a draw. Still 50/50.

  14. The Presidential vote matter not one whit when it comes to these laws - the makeup of the state government at the time of enactment of the statute is what matters.

    For instance, bright red Arkansas was a Democratic-controlled state in 2010 when Arkansas Code 23-17-409 was amended.

    The Iowa House of Representatives was majority Democratic when Ann 388.10 was passed in 2016.

    Louisiana was run by Democrats when 45:844.49 was passed in 2004.

    Michigan was largely controlled by Democrats when their laws were passed in the 1990s and 2005.

    Wisconsin's governor was Jim Doyle, a Democrat, and at least the State Senate was Democratic in 2007 when their law was last amended.

    That moves 5 states from the "Trump" column to the "Democrat or Democrat leaning" column when the laws were actually passed. That's a 12/12 split.

    I didn't check every single legislative / gubernatorial makeup, so maybe something was Republican that is now Democratic, or there might be a Democratic governor or two that I missed. (Both ECS and Ballotpedia have spotty coverage when it comes to dates and states). But, in general, this is a bipartisan attempt to screw us.

    I'd argue that the fact that Tesla isn't a car company is also part of the valuation.

    Everyone commenting on this article seems to have a vision of Tesla as it was several years ago (as a company that put electric drivetrains into Lotus cars). But Tesla hasn't been that in years - Tesla is a vertically integrated energy and transportation company. Electric vehicles are just the sexy front end - the Gigafactory, utility scale storage, SolarCity, and an actual live, working, iterating self-driving system are the market cap driving back end.

    Now, there's a lot of "maybes" in a lot of this, but Tesla could shut down the car division tomorrow and the rest of the company would be a compelling story.

The Gigafactory and the new utility-scale storage business are a lot of what's driving this valuation. The cars were a means to an end.

    I've never heard a good explanation why we don't use tidal energy to create the requisite pressure. Open gates at mean sea level, wait for high tide to flood reservoir, close gates, open much smaller exit path past filters during tide retreat, rinse, repeat. The massive water reserve attempting to push through the narrow exit path raises the pressure of the water.

    There must be a good physics or economics explanation as to why this doesn't work (not enough pressure, the amount of energy required to build the original system exceeds the amount of energy used by a regular desalinator, etc.).

    The American Expeditionary Force Siberia never had an intent at colonization. Its purpose was to help the Czechslovak Legion get back to the fight against the Central powers in WWI and to recover war materiel that had been staged for the use by the previous Russian regime on the Eastern Front. There was an early intent to fight against the Red Army (mostly to prevent the Germans from invading) but that was dropped almost immediately. A side aim was to prevent further Japanese colonization of the Russian Far East.

    Once WWI was over and the original goals were realized, the Americans left.

  24. Actually, mosquitos are an insignificant food source in almost all cases. The common claims that bats, or purple martins, are uniquely dependent on them is BS - stomach content surveys routinely show that they make up less than 1% of their diet. Even species of fish (e.g., mosquitofish) that purportedly eat large numbers of mosquito larvae turn out to overwhelmingly eat other things.

    In any case, there are only 40 species of mosquito that feed on humans, out of nearly 3,500 species. Of these, the worst, as you say, is probably Aedes aegypti, which is a recent invasive species everywhere other than East Africa. Wiping them out in the Americas and Southeast Asia can only be good and I don't think Africans would mind if we wiped them out there too.
