  1. Think about manufacturing on Lots Of People Really Want Slideout-Keyboard Phones: Where Are They? · · Score: 1
    I'm speculating here, but think about ruggedness and costs of manufacturing associated with a moving keyboard.

    Manufacturing:
    • Testing a moving part
    • Competing with thinner phones (keyboards add thickness)
    • Layout of phone given the need for a hinge, PCB, battery in the package
    • Relatively unique design; I imagine the assembly line for slate phones are very simlar
    • Finding a supplier for the keyboard

    Ruggedness:

    • Phones are quite water resistant now, a hinge gives more opportunities for leaks
    • Moving parts break
    • Individual keys break

    I think the only hope is for a nerd targeted phone, as people who need to type commands with weird symbols really benefit the most from a physical keyboard. But I am not holding my breath, and a bluetooth keyboard can cover the instances where I need to type in that fashion.

  2. Re:Wow. on Rocket Scientist Designs "Flare" Pot That Cooks Food 40% Faster · · Score: 1

    I admit that when I saw his design the first thought was backpacking only. Imagine washing something burnt off the bottom of that; I would only want to boil water in it.

    The issue with this pot in backpacking is that it looks heavier, and people get crazy when it comes to losing a couple grams. I imagine that you will save fuel in the long run but you also will have trouble storing stuff in your pot (my 1L pot is the perfect diameter for butane canisters to slide in).

    Props for the invention, and honestly if you want to make something expensive and marginally better than the rest of the products on the market backpackers are a decent choice.

  3. Re:Now I'm confused ... on New Chemical Process Could Make Ammonia a Practical Car Fuel · · Score: 4, Interesting

    It is a density issue. Hydrogen is difficult to transport and store. One solution would be to truck ammonia to the service station, where you can dump it into below ground storage and generate/compress H2 on demand. The other option would be to perform the H2 generation onboard of the car, but the issues of the toxicity of ammonia would still require fancy fuel tanks so I think the local generation model would be superior.

  4. Re:Where are they going to fab the chips? on Russia Wants To Replace US Computer Chips With Local Processors · · Score: 1

    No, but I don't know of any Chinese companies producing steppers or any other of the multi-million dollar tools required to fab a processor. You may be able to get away with used equipment but then you are giving yourself a handicap and won't get any support from the parent companies.

  5. Re:Where are they going to fab the chips? on Russia Wants To Replace US Computer Chips With Local Processors · · Score: 1

    I doubt that a fab could even be built as Russia is on a couple technology transfer lists. When they state Russian made I imagine it will actually be sent to TSMC or other foundry with design in Russia

  6. Safety Deposit Box on Ask Slashdot: How To Bequeath Sensitive Information? · · Score: 2

    You still control it, yet it is remote and will be properly searched when you die. You can put a usb key in or some paper documents with the relevant information.

  7. Re:Kerbal Space Program on SpaceX Falcon 9R Vertical Take-Off and Landing Test Flight · · Score: 2

    If KSP has taught me anything, it is that computer controlled rockets (MechJeb) can land vertically very reliably.

  8. Still not as good as Bose Active suspension on New Car Can Lean Into Curves, Literally · · Score: 1

    I'm still waiting for this to be mainstream

  9. Re:It nearly exists on I Want a Kindle Killer · · Score: 1

    Thank you for posting this, it is almost exactly what I've been looking for. I wish there was a discount version without the radio/solar for urban backpacking, and a colour eink would really help with maps, but I'm thrilled to see demand for a traveler's eink device.

  10. I want the hitch hikers guide on I Want a Kindle Killer · · Score: 1

    It isn't that far off. An eink reader designed for travel, with lonely planet or wikisherpa included. It is also one of the few proper applications of a colour eink screen, as maps do not need to be vibrant but colours are vital to a map.

    I could go on, but I know this is a fantasy. I hope one day a colour eink android or linux tablet arrives so I can install applications similar to this use case, but I am not holding my breath.

  11. Re:Seems somewhat predictable ... on How Predictable Is Evolution? · · Score: 3, Insightful

    Convergent evolution also depends on how you define two features similar. For example, the convergent evolution of oxygen carrying blood in Cephalopods could be a counter example to the prediction argument, as their blood has oxygen bind to copper.

    So both bloods were evolved to perform the same task of moving oxygen, however they use two different mechanisms to perform the task.

  12. Hydrogen is both on Future of Cars: Hydrogen Fuel Cells, Or Electric? · · Score: 1

    Hydrogen vehicles these days are series hybrids with a PEM fuel cell and Li battery pack. Think of a Volt but fuel cell instead of ICE.

  13. Other countries on Why Mobile Wallets Are Doomed · · Score: 2

    Just let these innovations arise in other countries if the USA has such a backwards infrastructure. Even credit cards are more secure in other countries (chip and pin may be flawed, but it is still better than the magnetic strip and signature of the USA).

  14. This can only happen if we avoid mobile OS bloat on The Feature Phone Is Dead: Long Live the 'Basic Smartphone' · · Score: 1

    It is easy to claim that Android can be used on these types of devices, however these devices will have little memory to keep price down. If you could load Android 4.x onto the original HTC Dream then by all means bring on the low end phones.

    Still waiting to see how FirefoxOS compares, as they are going after the low end market but I know that Firefox on Android is not the best with limited memory (I believe that Opera Mobile takes that title, so naturally it is discontinued).

  15. Car anology please! on The Ways Programming Is Hard · · Score: 2

    I just don't get this bridge thing... I know cars drive on them but how does that relate to anything!?

  16. Re:And As Usual... on OnePlus One Revealed: a CyanogenMod Smartphone · · Score: 1

    I used to think that reliability was also a reason for the non-removable battery, however the new Samsung S5 claims to be certified for dust resistance and water to 1m.

    For the daylight readable screen I've never seen any phone with one (or ebook reader or tablet for that matter), so I suspect there is just a lack of technology. We've seen prototypes and demos, but there may just not be high volume manufacturing in place for these screens.

  18. Re:Here's the problem on OnePlus One Revealed: a CyanogenMod Smartphone · · Score: 1

    Have you investigated the virtual network operators? Cricket was just bought by ATT and will remain relatively independent, but borrow their towers.

    But yes, I agree, whenever a new phone comes out that looks exciting I think how it does not help me, although the Samsung S5 is coming to Virgin Mobile so I may move to that depending on price.

  19. Re:Too good to be true? on OnePlus One Revealed: a CyanogenMod Smartphone · · Score: 2

    Keep in mind that teardowns of the S5 put the manufacturing cost ~256USD. While this does not take into account a lot of costs like design, if the OnePlus One is selling at zero profit to gain market share they could with similar specs to the S5.

  20. Thermal Management on Will the Nissan Leaf Take On the Tesla Model S At Half the Price? · · Score: 2

    When the Leaf first was introduced, people in the electric vehicle industry were floored that the Leaf relied on air cooling for the batteries, and at that it is passively cooled. I cannot imagine continuing this with a larger pack; while the load per cell goes down, if you are trying to make a denser pack you will need to include liquid cooling to pull heat out. Liquid cooling is more expensive than air cooling to develop/produce, so it will be interesting to see what Nissan comes up with in the final implementation.

  21. National Geographic on Ask Slashdot: What Good Print Media Is Left? · · Score: 1

    Easy enough to leaf through, colorful enough to justify printing. I keep one in the map pocket of my car for waiting at airports.

  22. Re:Partial statistics on Steam's Most Popular Games · · Score: 2

    I thought HL2 ep2 was awesome, and ep1 was fun also, I'd suggest checking them out (only 20 hours if you milk them) if you enjoyed HL2

  23. Some error on unplayed games on Steam's Most Popular Games · · Score: 5, Interesting

    Probably not a major factor to the whole study, but there are two issues for detecting the game being played by time played:

    1. The time played started being recorded a couple years ago. Games played before that default to zero. For example, I put on probably hundreds of hours of Counter Strike 1.6 in High School, but it is listed as unplayed in my Steam profile

    2. I didn't see how they handled game expansions, which are often listed as separate games, but they are unplayed. For Borderlands, I have four additional "games" with no playtime

  24. Re:AZ License plates on Can You Buy a License To Speed In California? · · Score: 2

    With Intel fabs in Oregon (slowest state by far) and Arizona (one of the faster states), you feel the difference when traveling for work.

  25. Google Docs on Ask Slashdot: How To Start With Linux In the Workplace? · · Score: 1

    The easiest way to switch off of Windows would probably to move to Google Docs. Still costs money (I don't know what business accounts cost), but you can keep employees on Windows in the nearterm and transition only from Office to Docs, then introduce Linux relatively painlessly.
