Comment Re:How many bits? (Score 1) 74

I work for Dolby Laboratories, and am deeply involved with high-dynamic-range content creation and hardware.

We created the SMPTE 2084 standard HDR EOTF (electro-optical transfer function.) It turns out that human perception is such that by choosing the luminance for code values to be just barely indistinguishable from the adjacent ones, you can get 0 to 10,000 nits (10x as bright as this Panasonic display) with only 12 bits. SMPTE 2084 is what all HDR TVs are using today.

Comment Everything Old is New Again (Score 1) 51

The Andromeda Strain was published in 1969.

The United States has some disease reporting, it started at least 75 years ago before the antibiotic bubble. This CDC Report summarizes the present state of disease reporting, in two pages. We need higher standards of reporting and legal penalties for failure to report.

Comment Re:Why air gaps? (Score 1) 209

Double glazed windows have a vacuum (or sometimes a noble gas) between the panes.

Or dry air. There's no need to use anything other than air to avoid condensation. You just need to make sure the air is dry and the windows are sealed so humid air can't get in. I doubt many windows are vacuum-filled; that's just begging for trouble, and would also limit the size of panes. 15 pounds per square inch adds up to a lot of pressure very quickly.

Comment Re:No investment opportunities big enough (Score 1) 112

Apple : "We have so much money we literally don't know what to do with it anymore."

That's alright. Neither do Google or Microsoft and a few others. They simply can't find investment opportunities large enough and profitable enough to do anything with their piles of cash. So the pile keeps growing. Eventually I expect it to attract a dragon or something.

Really they should be paying it back as dividends if they can't figure out what to do with the money.

The reason they have large piles of cash isn't that they can't figure out what to do with it, it's that it's cash they generated overseas they can't move it to the US without giving 35% of it to the federal government. They can't pay it out as dividends without repatriating it, nor can they invest it in anything in the US. Since most of their operations are in the US, that means they spend a little on overseas operations and put the rest in high-liquidity overseas investments -- high-liquidity in case they get an opportunity to repatriate it cheaply, or have a sudden need that makes the big tax bite acceptable.

Bottom line: the reason they have big piles of cash is because the US has the highest corporate income tax rate in the developed world.

Don't try that crap with Frontier, or you will 100% get screwed. They leave early on purpose so they can make people pay the re-ticketing fee.

If they close the door too early (not sure what the line is), they not only can't charge you, they have "involuntarily refused boarding", in FAA terms, and they are required to buy you a ticket on the next available flight (on any carrier) to your destination, and pay you a cash penalty ($500?). This actually happened to me once.

Comment CPU cycles area cheap. Bandwidth is not. (Score 1) 56

I don't care in the least if my computer sits idle for a few seconds waiting for me, the user, to tell it what to do. I care very much if it arbitrarily decides to waste some of my all-too-limited monthly bandwidth incorrectly trying to second-guess my intent.

Dear Silicon Valley (or in this case, Oslo): Kindly fuck off and quit acting like the whole world has the same nice gigabit FTTP connections you've come to enjoy. Over half of the US (and more than half of the planet) doesn't have effectively unlimited high-speed broadband available. Please behave accordingly.

Ah yes, pay the extortion fee to regain your rights back as a conditional privilege. Thanks for making our lives easier, Toilet Safety Administration!

Yep, it sucks. But as a practical matter, if you travel regularly it makes your life much easier. Most of the time. You don't always get TSA Pre, even after paying the extortion fee. But you get it 90+% of the time, and are happy you did, especially when lines are long and you are carrying a lot of crap.

TSA Pre has allowed me to return to my pre-9/11 habit of arriving at the airport 25-30 minutes prior to departure, so that by the time I reach the gate I can walk right on. BTW, I don't recommend this habit unless you can afford to miss the flight, because maybe one time in 30, you will. But the 29*0.5 = 14.5 hours you'll save by doing it are worth the two or three hours you lose when you miss your flight and have to catch the next one. When the flight I'm on is the last of the day, I make sure to arrive 60 minutes before.

Comment Re:Read the first volume (Score 1) 358

It's also well worth the effort (and it is a lot of effort) to read the third volume, Sorting and Searching. The second volume (Seminumerical Methods) may be useful if you do certain kinds of work, but Fundamental Algorithms and Sorting and Searching are worth almost any professional programmer's time.

I have to admit I haven't bought 4A yet.

I really hope that Knuth is grooming someone to take over the work of completing the full set when he dies, or becomes unable to continue.

I'm always careful to grab mine, but with all the bullshit rules these days I have FOUR FUCKING BINS plus my bag to take through TSA.

It's complete fucking security theater. Stop requiring removal of all these devices that just slow down lines and lead to lost items. It's all bullshit.

If you travel much, pay the money ($100) and go through the process of getting your Global Entry card, which also gives you TSA Pre-check. It's well worth it for the hassle it saves. For a little less ($85) you can sign up for TSA Pre only, but if you ever leave the country the $15 extra for Global Entry will make re-entering the US much easier. I recommend Global Entry even if you just think you *might* travel internationally.

Submission + - How to View the SpaceX Falcon 9 Return to Flight at Vandenberg Air Force Base (perens.com)

Bruce Perens writes: Silicon Valley folks should, sometime, take the opportunity to view a launch at Vandenberg Air Force Base. Lompoc is 4-5 hours from the Bay, 2.5 hours from LA if there's ever no traffic. An upcoming SpaceX launch is notable because it's their return to flight, months after their last attempt blew up on the pad during a pre-launch test. Read how to view the launch.

Comment Re: Less politics (Score 1) 110

Eich resigned because of external pressure on the Mozilla organization. I hear that one of the lobbying activities against him was when the dating site "OK Cupid" started informing Firefox users who accessed the site of Eich's activities and that they should download a browser made by people who don't nominate someone with gender discrimination issues to be their CEO. At the time, 8% of OK Cupid customers were there to arrange same-gender meetings.

They felt he was the public face of the company.

Russ Nelson published a piece on what he theorized was the economic motivation of Blacks to be lazy, and was booted off of the Open Source Initiative board. He wasn't thinking about how it would be perceived. A modified version of the piece is still online, but not the version that got him in trouble. In general, executives are seen as the public faces of their organizations even in the case of Nelson, who was not the chairman of the board, but was simply a member of the executive board. In Nelson's case, it wasn't that he made publicity appearances and press releases, it was that he was one of the people with the power to direct the company (and thus a more real face of the company than soneone who just does PR), and folks did not trust that someone who wrote what he did would behave as they would like in that position.
