    Bioinformatics software is horrible. I've written way too many data format converters/massagers for software that doesn't like to comply with standards. My adviser has changed up the specs on the software -which I've been coding over that last two years- to now ignore the data format standards in order to add a minor function.

    Somehow my adviser doesn't understand why changing the specs to a non-standard data format would be upsetting

  7. Re:Because there is no money in STEM... on Reversing the Loss of Science and Engineering Careers · · Score: 2

    There are two ways to make money in the world: Make a bigger pie, or take a piece from someone else. The pie isn't getting any bigger in the US with zero technology advances, the fact that China kills any US industry that seems promising (solar? Hack the US companies, slurp up the trade secrets, then dump the panels for cheaper than they can be made. A PRC victory achieved), and the fact that the US politicians are more interested in "terrorists" and political infighting than actually doing anything to advance the countrey

    Actually the pie is getting bigger, the Dow is higher than it's even been, and the average income is pretty good. But the problem is that the median is getting worse and worse. The rich are getting richer, the world is getting better, and yes the PRC is kicking our tail because they have build a proper manufacturing economy and we have blown our domestic manufacturing supply chains to smithereens.

    We are far from an "everything has been invented" stage.. Have you been looking at medicine and biology.. or the video of Bret Victor doing real time coding.. or the self driving cars from Google. or the Natural Gas Industry that's changing our power dependencies.. or the gigawatts of wind power that have become viable.. crazy data mining.. cell phones.. led lighting, oled screens, xray backscatter technology, terahertz technology, aerogels, graphene, nanotubes, diamond vapor deposition, flourinert, DeconGel, superhydrophobic surfaces, biomimetic gecko tape, rapid DNA sequencing, full dna replacement of a bacteria, transgenic everything (hypoallergenic cat anyone). multitouch surfaces. the cloud. 50 computer cores per chip-- knights corner. Stuxnet virus..

    ...... I completely reject the premise that were are remotely close to an "everything has been invented" phase of history

    Law is pretty overpopulated, too much lawyer drama on TV, same with forensic analysis.

    Your question needs clarification

    Are we assuming that there was no sort of error checking on the input to begin with?
    so can someone place 2 9's in the same row, column or square?
    if so you need to check all the non clue squares.(now max of 64)

  16. Re:Don't genetically modified silkworms... on Genetically Modifying Silk Worms For Super Silk · · Score: 1

    Oddly spinning silk is tough to do from proteins. Even if you extract the goo from inside the spider and try to spin it- it's a mediocre fiber. Synthetic leather is a ways off. There isn't a compelling reason to make synthetic wool, as current wool is made without all of the industrial waste of nylon, and comes in significant quantities, and it's a fine renewable.

    We spray a whole lot of insecticide, killing a whole lot more bugs just for cotton, and those insects feel pain. If we decide that were going to be nice to nature, it is going to bite us back or were going to have to be hypocrites about it. I understand the concept of not hurting bugs, but It isn't realistic. Insects are everywhere, and killing them is part of getting what we need. Bedbugs and lice are drowned by the millions in hotel washers every day.

    Bugs are important to the environment, but we cant worry about their pain.

    Nope, different research groups that were in the same wing. The spider goat guy (Randy Lewis) is more of a protein researcher. Don Jarvis (spider silkworm) studies sugar additions to proteins, insects have some interesting gylcosylation pathways.

  18. Re:AMD on Ask Slashdot: Parallel Cluster In a Box? · · Score: 4, Insightful

    Because it's new, and finding someone who's done it to get some pointers is really hard.
    CUDA has been around a while, figuring it out isn't such a rough learning curve.

    Overall I'm a little suspicious of someone looking to use a GPU for more threads on a problem. As going the GPU route is a really committed step, and the programming gets a new level of complicated. Using multiple cards has some odd issues in CUDA, ie. If you exceed the card index it defaults to card-0, rather than crashing. There are more places to screw up with a GPU- transferring memory- getting blocks, threads, and weaves organized(if done properly it hides all sorts of latency in calculations, done poorly it's worse than a CPU)- avoiding memory contention (the memory scheme isn't bad, but it needs to be understood).

    So in most cases I'd first start with this chart http://www.cpubenchmark.net/cpu_value_available.html and tell them to cut their teeth on a GPU with a smaller(cheaper) test case.

    Um re-watch it, they consider the issues of landfills in that episode. And mostly they claim that it's a "sky is falling" problem. We aren't running out of landfill space any time soon. Of the problems in this world, the lack of plastic recycling is pretty low on the totem pole.

    When it comes to sorting garbage, let the robots handle it; I want people to have an incentive to get the trash into the trashcan. Ever seen the garbage in Delhi? It makes me very happy to pick up loose garbage when I see it.

  21. It's not supposed to be a trade school on Reading, Writing, Ruby? · · Score: 1

    A Computer Science degree should imply that the holder is capable of:
    A fair degree of applied math
    Being able to build a formal proof (prove sqrt 2 is irrational)(of which a real math major will laugh at)
    Able to write a simple compiler or a simple operating system.
    Able to track down a reproducible bug in a medium complexity program

    Plenty of people get in it for the wrong reasons, and will cheat their way through the rough stuff.. horrible when I see someone who "passed" compilers not understand what LL parsing is or able to read a context free grammar.
    The world is better off with solid coders that have a clue, lots of them. Even minor coding skills can become really useful in all sorts of tedious work.
    It's always someone else who is incompetent.
    I would prefer someone else to proclaim my competence, as self-proclaiming is specious at best.

    The big problem is that today when you have innovation in the US there's always a risk of encountering one or more patent trolls which costs a lot of energy to fight.

    Agreed, our parent/copyright system is jacked. We're sending away foreign nationals that we educated. The ability to make a small business work is still tricky, as getting decent insurance is a mess. Banks aren't really good to small business either, CC machines are a horribly unfair system to a merchant. While corruption isn't rampant, it is not an oddity. Narcotics prohibition cause all sorts of down stream effects. Many people are still waiting for the economic bubble to pop, or finish popping.
    A good chunk of what America has been providing to the world is banking -- our economic instability has damaged our reputation. We need to build longer term stability with less turbulence. We need a revamp of patent law/intellectual property law. We need an enforceable framework for digital property.

    I look around and see a bunch of people with well considered ideas for products, Even ones that would be reasonable to implement are hosed by a cranky system.

  25. Not so worried about quantum on Ask Slashdot: Post-Quantum Asymmetric Key Exchange? · · Score: 4, Interesting

    Quantum entanglement is being studied hard by bright people, who are publishing. I think that the technology is a ways off, and I expect that there are some limitations on entanglement. Being able to collapse 2^2048 super-positions seems a bit preposterous to me. I could be horribly wrong, but I have a feeling that there are going to be limits on how many "entanglements" can be made by a given subatomic particle.
    I'm a bit more worried about someone who finally get's a eureka on factoring large numbers. Then the genie is out of the bottle, and no-one knows it. Heck it might already be cracked, and held as a state secret, only makes sense.

    What would you do if you had a factoring algorithm that could factor a RSA number as fast as the generator could make them?
    What would be the fallout?
