  1. Re:DIY a Raspberry Pi laptop... on Ask Slashdot: Which Laptop Should I Buy For My First Employee? · · Score: 2

    Not amazing. Tiny market for the laptop bits sans motherboard, so pricey. Fixed costs become really important -- inventory, interest on the loans, up-front charges for molded plastic cases (even worse for metal stuff), billing, return handling, etc. There's a hell of a difference in what you pay for keyboards if you buy in lots of 100 rather than 10,000. Hand assembly, if the market is that small, is shockingly expensive.

  2. Re:3 Main Bullets on 'The Five-Paragraph Essay Must Die' (psmag.com) · · Score: 1

    Yep. Five paragraphs of single-spaced text in a reasonable font also fits nicely on one side of one piece of paper, which is the limit for writing a take-away summary for upper management. Lived by that rule for decades. If it has a staple they won't take it; if they have to turn the page over they won't finish it; always put the most important point first, because they may not finish any way.

    I read Uncompromising Honor, it really suffered from 'wrap it up' syndrome, I thought.

    Yeah, same thing with the last Safehold book the year before. I have heard that Weber has some serious health problems. I assume he's going to let Eric Flint do the heavy lifting to wrap up the Alignment aspects of the story using Zilwicki et al as protagonists.

    A bunch of that time the box is waiting for the downstream feed with channel lineup and content to arrive. It's a legacy national feed, tied down by a bunch of ancient business contracts, so your box waits while Cleveland and Boston and Salt Lake City's lineups go by.

    A channel change means frequency change for the analog tuner, dynamic gain adjustment, sync to the MPEG transport stream, sync up the decryption hardware, start extracting the particular content stream, wait for a B frame to come along, and finally start putting up the image. All spec'ed out by the standards bodies 25 years ago.

    Change it? It took more than a decade of lobbying to get the FCC to approve dropping analog NTSC carriage.

  5. Get the tense right on The US Grounds All F-35 Jets (bbc.com) · · Score: 1

    The U.S. has spent more than $320 billion to build their fleet of 2,400-plus F-35 jets...

    Will spend. Maybe. Fewer than 350 have been delivered to date. Current production is less than a hundred per year, predicted to reach a maximum of 160 per year by 2023. My own guess is that fewer than 1,600 will actually be built.

  6. Oh, absolutely. The terms of employment required me to agree in advance that I would assign the rights to any patents to the company in exchange for a "consideration". Amusingly, one of the giant corps gave every inventor a plaque when the patent application was submitted. Along with the patent title, inventor's name, and the date, there was a dollar bill mounted on the plaque -- a dollar being the smallest consideration that was legally binding under the case law in that state.

  7. His own patents? on GE Engineer With Ties To China Accused of Stealing Power Plant Technology (thestreet.com) · · Score: 5, Informative

    Zheng's attorney disputed the allegations, saying Zheng "transmitted information on his own patents to himself and to no one else."

    My experience with giant corporations is that I sign away the rights to the things I invent for them as a condition of employment. "My" patents are at home, with documentation that they were all done on my own time, using my own equipment. And even that may be subject to litigation if the patents fall into the same type of things that I develop at work.

  8. Depends on the sport, probably on Should Professional Sports Switch To Robot Referees? (hpe.com) · · Score: 2

    Consider this bit of conventional wisdom about the NFL: "The holding rule for offensive linemen is violated on every play." Instead of the rule as written, there is something else that is actually enforced. And the enforced rule is a whole lot more complicated. Grabbing the opponent's jersey is allowed if you don't extend your arm too much. If the opponent doesn't attempt to pull away far enough that the held jersey obviously stretches. And a lot more exceptions.

    Don't even get me started on the NBA. An AI referee that called the rules as written would foul out the entire lineup for both teams in the first quarter.

  9. Re:business executives? on Are Tech Conferences Overrated? (cnn.com) · · Score: 1

    Yep. For me, the basic qualifier to make it a tech conference is, "Do they publish proceedings?" If not, then as you say, it's business/marketing/media.

  10. Anyone else remember the chimera browser from about the same time that could also do embedded images? Not the Mozilla-based one that became camino, but the original 1.x versions (from UNLV, I think?). Looked at my old lab notebooks and I used that chimera in a series of demos with homegrown video-over-IP in April, 1995. Didn't embed the video in the browser display proper, but added code to let the browser fork a separate video-over-IP player that displayed the stream.

  12. Look at who wrote it... on Silicon Valley Is Over, Says Silicon Valley (nytimes.com) · · Score: 1

    I have to admit that I find it amusing that the NY Times is, in effect, going to lecture me about how the Midwest will reverse a >60 year pattern of migration and "brain drain", and take a significant number of jobs from California and the West.

    Just as supporting evidence that the flow hasn't slowed particularly in recent years, the Midwest and Northeast states are currently projected to lose eight seats in the US House to the West and South after the 2020 census.

  13. Re:Need a New SV? Why Not Detroit? on Silicon Valley Is Over, Says Silicon Valley (nytimes.com) · · Score: 1

    Immediately to the north/northeast of Detroit is Oakland County. Population 1.2M, one of the 25 richest counties in the country by median household income (top 10 if you only consider counties with >1.0M people), one of the largest concentrations of engineering jobs in the country. When a new research or design center is opened in the area -- and that happens from time to time -- they very carefully site it in Oakland County, where the real estate prices are much closer to an Austin or Denver than to Detroit.

    Ask why none of those firms are willing to go into Detroit.

  14. Windows-specific problem? on Learning To Program Is Getting Harder (slashdot.org) · · Score: 1

    A good deal of the problem described in the original post -- lack of any sort of IDE -- appears to be mostly Windows-specific. Macs come with Python, Perl, and vim installed. Most Linux distributions come with all of those. Heck, most Raspian distributions for the Raspberry Pi come with all of those (one of the first things I did when I fired up my first Pi was to write and run "Hello, world!" in all of C, Perl, and Python, without installing anything extra). The Python standard library includes a GUI. Tcl/Tk may be a terrible GUI, but you can learn to open windows, add buttons, listen for events, etc.

    Fuss at Bill Gates, or whoever's in charge these days.

    Then let the rural areas demand higher prices for their products, and see how far they get. (Note: too many family farms have sold out to large corporate interests; it won't work.)

    Everyone sells their products. Everyone pays their property and sales and income taxes. The state collects a pile of cash and distributes it. In a substantial majority of cases, the result of formulas is that suburban areas send money to the rural areas (urban areas too, but less so).

    A few years ago Colorado had a 51st State movement. I had an opportunity to interview one of the principle movers. I pointed out that when they cut themselves off from the urban/suburban areas, they would not be able to afford to have a state university, would have to let hundreds/thousands of miles of paved rural roads revert to gravel, and leave tens of thousands of people without health insurance. You know what he told me? "Those are features, not bugs."

  16. Interesting budget quandry... on 'New California' Movement Wants To Create a 51st State (wqad.com) · · Score: 4, Insightful

    If you dig into the details of the current California budget and look at the cash flows for roads, schools, medical care, and a couple of other things, what you find is a huge amount of money transferred from the coastal areas that would be in one new state to the rural areas that would be in the other. This is not unusual; it happens in a lot of states. (I used to do that kind of study professionally.)

    Split the way it's drawn, the rural need for subsidies would remain largely unchanged, but the burden to provide the money would fall solely on the few cities (San Jose, San Diego) and their suburbs that got stuck in the rural state. Given a choice after they see a draft budget, San Jose and San Diego are going to scream about being included in the rural state.

  17. Re:States' Rights on What Happens When States Have Their Own Net Neutrality Rules? (bloomberg.com) · · Score: 3, Informative

    The preemption doctrine has been around for a long time, and has been consistently upheld by the Supreme Court: once the feds decide to regulate, states may also regulate only to the extent and in ways that Congress specifies. With the default case being, if Congress doesn't specify, the states can't regulate.

    For example, the Clean Air Act explicitly gives California authority to set tougher-than-federal emission standards for some things (cars in particular) -- it's right there in the statute. Other states are given authority to choose between the federal standard or the California standard where they are different, but no other state can make up its own standard.

  18. Cost on New Bill Could Finally Get Rid of Paperless Voting Machines (arstechnica.com) · · Score: 3, Informative

    The big question is, "Congress might mandate it, but are they willing to pay for it?" In most states the cost of the voting equipment falls on the counties. Any that bought voting equipment in the last decade are going to fight tooth and nail against having to replace it. I have a friend who works in the electronic voting machine business; she tells me that they're still doing repair work on 20-year-old machines because of counties who don't have the money to replace them.

  19. Re:I like paper ballot on New Bill Could Finally Get Rid of Paperless Voting Machines (arstechnica.com) · · Score: 1

    I live in a western vote-by-mail state, with some centralized polling places for people who were not registered in time to have the ballot mailed to them, or who prefer to vote in person. Waiting time is, for all practical purposes, zero.

    Opinion polls done after the system had been used a couple of times asked the question, "Should the state retain its vote-by-mail system?" The answer was yes across the political spectrum: >75% of Republicans and >80% of Democrats and independents. Over 30 years, I can't remember any other political question getting that kind of support here.

    A large majority of all ballots are cast by mail when the American West is considered as a whole (either 100% vote-by-mail, or permanent no-excuse absentee ballot lists). No one in the West thinks that there's significant fraud. OTOH, I read a lot of East Coast pundits who insist that it must be there, we're just too stupid to find it.

  21. One of my long-standing complaints about the Web was/is the number of pages that tempt you to ask the designer, "Did you have to study ugly and unreadable in school, or are you just naturally talented?" Font choices, both the number used and the fonts themselves, are a significant part of that.

    A couple of years ago I did everything I could with preferences and a user .css file to limit things to one of two fonts. Then I wrote a GreaseMonkey script that goes through almost every page I download and replaces styling with one of those two fonts, and one of a handful of sizes. I'm a whole lot happier with how the Web looks these days :^)

    Good of you to point out that the actual problem is something much harder than described in the OP.

Not just polynomial, but linear.
