  1. Fair is Fair on Six-Strikes System Starts In U.S. · · Score: 1

    OK - so if you in the US have to force your "3 strikes" baseball metaphors on the rest of the world it's only fair that we make you call this one "6 balls and it's over" using a similar cricket metaphor - despite the, um, unfortunate cultural double meaning of the expression in the US

  2. Re:Layout by HAL on iPhone 5 A6 SoC Teardown: ARM Cores Appear To Be Laid Out By Hand · · Score: 1

    well a cpu with a 1GHz clock has 1nS to process data between flops - yes it's a bit like laying out microwave stuff -but in the very small - what happens is that it all starts with some layout person/people creating a standard cell library, they'll use spice to simulate and characterise their results - they'll pass this to the synthesis/layout tool makes a good first guess, they'll add in some fudge factor - then a timing tool looks at the 3d layout and extracts real timing, including parasitics to everything in 3-space around a wire - they check - does the timing from every flop to every other flop through every possible path meet both setup and hold times for the destination flop - if it does you're golden, tape it out - if not tweak something or resynthsise a block with tighter constraints etc etc

    There is very complex delay analysis done - in all corners of the underlying fab process - automated layouts seldom look "pretty" at least from the point of hand done boards

  3. Looking closely on iPhone 5 A6 SoC Teardown: ARM Cores Appear To Be Laid Out By Hand · · Score: 5, Informative

    Looking closely I see a bunch of ram - probably half laid out by hand (caches) - and a many may small standard cell blocks almost certainly not laid out by hand - what I don't see is an obviously hand laid out datapath (the first part of your CPU you spend layout engineers on) - look for that diagonal where the barrel shifter(s) would be. There are some very regular structures (8 vertically) that I suspect are register blocks.

    Still what I see is probably someone managing timing by synthesizing small std cell blocks (not by hand), laying those blocks out by hand then letting their router hook them up on a second pass - - it's probably a great way to spend a little extra time guiding your tools into doing a better job to squeeze that extra 20% out of your timing budget and give you a greater gate density (and lower resulting wire delays)

    So - a little bit of stuff being done by hand but almost all the gates being lait out by machine

  4. Business as usual on GNU/Linux Running On An 8-Bit Processor · · Score: 1

    I've worked as a logic monkey building CPUs in the past - this is SOP in our world - we'd boot linux on our hardware on the verilog simulator as part of our QA - 2 hours is nothing .....

    It's not even a new idea 20 years ago I used to port Unix for a living (no linux yet), when the early RISCs came out they came with architectural simulators, while waiting for real silicon we'd spend the time bringing the kernel (and compiler) up

  9. No where to buy on Music Execs Stressed Over Free Streaming · · Score: 1

    I used to regularly buy a CD or two a week, but all the good local music stores have closed leaving chain stores full of pap - if I don't regularly browse I'm just not going to buy.

    Sure I could buy on line but I really don't get the opportunity to find new stuff that interests me Pandora doesn't stream outside the US and besides buying from Amazon from outside the US is really expensive - and of course one can't buy from iTunes from a linux box because of Apple's lousy support

  10. Don't do what I did on Equipping a Small Hackerspace? · · Score: 1
    Years ago, in my first job out of college, i was tasked to do just this - I spent a day wandering around town looking in hardware stores - a lot of the old guys behind the counter would snigger and make a smart comment - it wasn't until the end of the day I realised that "do you have any small vices" might have another meaning ....

    Just last month I found myself at the local big box hardware store looking for - you guessed it - looking for a small vice .... with a wonderfuil sense of deja-vu I got to pop the question - the young whipper-snapper there didn't even blink and took me to the aisle with the vices - kids these days, just oblivious

  12. Newspaper on Capturing Carbon With Garbage Heaps · · Score: 1

    I've always been a big fan of recycling but recently I've realized that recycling newspaper is probably wrong - it drives down the cost of wood pulp at a time when we ought to be providing economic incentives for people to plant more trees. We're better off sequestering its carbon - down some old coal mines or the equivalent - yes I know there are issues with methane and land fills but I see those as being things that one can spend some money on researching technological solutions for not just a reason for rejecting the idea out of hand.

    Well to be fair he's a nutter, part of a right wing party that seems to have jumped the shark at this point, he was the proponent of our '3 strikes' legislation - when this was announced in parliament today there were shouts of "strike two".

    The main reason why the government started doing that in 2005 was because we had discovered that Israeli spies had been doing exactly that thing, getting fake NZ passports using the birth certificates of dead babies - the police went back through the records to hunt down any such passports, to cancel them to protect our citizens traveling abroad.

  19. Re:not proportional voting, rather representation on "Cumulative Voting" Method Gaining Attention · · Score: 3, Informative

    I think you're misinformed about how such things work. Here in New Zealand we use something very like the German system - while the tiny details may be different the basic idea is the same.

    Parliament or whatever has N seats, everyone gets two votes:
    - the first is for a local representative elected using FPP almost exactly as you do for the House in the US - there are N/2 local representative seats.
    - the second is for a party, after the first set of votes are counted and the number of party representatives with local seats are determined the total party votes for the country are tallied - the second N/2 seats are allocated to representatives off of party nominated lists so that when added to the first N/2 the party seat count in parliament comes out according to the second vote

    There are various details around minimum votes to get party seats and various rules for strange overhang situations that those can create that are different from system to system.

    And yes we haven't had a single government since we changed to this system where a single party got 50% or more of the vote - all governments have been coalitions - it means politicians have to make public agreements and compromises which result in them acting more constrained in their actions than they would have been if they'd gotten 30% of the votes in an FPP election but 60% of the seats - it's a wonderful thing - many of the politicians, especially the old school ones, hate it.

  23. Re:Nothing to see here.... on Memory Management Technique Speeds Apps By 20% · · Score: 2, Interesting

    I've worked with real multi-threaded apps that turned out to use more than 50% of their time in malloc/new free/delete and the associated locks - large;y due to the use of C++ string routines by people who didn't understand the single threadedness that was going on behind the scenes. The most important thing to take away from this is that malloc/free are not cheap, they involve synchronization in multithreaded code (like stdio and most people don't know that either). (and should be avoided like the plague in real-time code because of the risk of priority inversion)

    "At those voltages millions of amps can be delivered safely to the transformer that feeds your home."

    Umm ... to give you the benefit of the doubt let's assume you meant "At those voltages millions of amps can be delivered safely from the transformer that feeds your home." ... so the basic rule about transformers is that when the step down the voltage ratio they step up the current by the same factor ... so 45kv->110v is a factory of ~400 - to provide 2 million amps to the home at 110v you need 5000 amps running in those 45k lines - they're going to be glowing ....

    Quite apart from that you can't do anything safely with a million amps, except maybe run away ....
