  1. Hackers have always been around in Dark Souls. 

     

    But with DS3 being friendly to beginners and becoming so popular, it's become even worse. 

     

     

    The issue with hackers is that most of them are GOD AWFUL. I'm not just talking new player bad, I'm talking they don't learn from their mistakes bad. That's why they hack. They don't understand why they can't just spam one attack and people don't die. 

     

    Dark Souls PVP is a fighting game, pure and simple. If you can't mix it up, you will lose. 

     

     

    DS2 footage, mmm delicious

     

     

    I came across my first hacker probably two weeks into launch of DS3. Infinite stamina and health, and he was invading! It wasn't even like I invaded them and he was just "Defending himself" (Because that's the defense they always turn to). 

     

    He chases me around until I positioned him next to a cliff. Then I rolled around his super slow attack and backstabbed him right off the cliff. He then sent me a message saying that I was "A noob hacker mother fucker". Yeah, ok pal.

  2. How did the later trial phases go? 

     

     

    We were on a fast-track phase 3 when the FDA fucked up and allowed a few shitty drugs through on that program and it ended up killing some pregnant chicks. 

     

    So the FDA rescinded the fast track option for no reason after we had a contract, so we were stuck on phase 2. But phase 2 and early phase 3 was really positive. Our initial phase had stage 4 patients that were either cured or had their lives helped so greatly that we were shoved into a phase 2 early on and were perfect candidate for a fast track.

  3. My first job was at a start-up biotech company who's patents included an Anti-IL-1 alpha Antibody. 

     

    I was in charge of the production of genetic sequences that would be placed into plasmids, incorporated into E.Coli, and then grew up to be harvested and transfected into eukaryotic production cell lines that would in turn produce the appropriately folded massive protein that is the anti IL-X class of biomolecules. The X here represents any number (IL-1, IL-2, IL-5a, etc). 

     

    Through this work I did a ton of research into tumor biology and metabolism. Our main product would inhibit the use of the inflammation pathway by tumor cells. This stopped the angiogenesis of capillary beds by the tumor mass and impeded its growth. Since cancerous cells are, by definition, entirely unstable, the loss of angiogenesis stopped the growth and led to the eventual metabolic demise of the out of control mass of cells. 

     

    This was done in time for the host's body to maintain its own metabolism, unimpeded by the massive growth of the tumor. Our initial trials were glowing, with an extremely high number of cancer patients turning the tide of battle against their own tumors. 

  4. I've still been using my PSE Kingfisher quite often. My Chinese carbon arrows are cheap and heavy, but they work. I can now shoot comfortably from either a left or right handed stance (Even though the bow is set up right handed) and am now working on knocking out the 10" circle of my target at ten yards. 

     

    I started shooting left handed until I realized that I'm doing exactly the opposite of everyone else with my handiness. 

  5. Fun fact, you can get the Asylum Demon to keep doing the big butt-stomp attack if you continuously attack the butt. Maybe that's what the camera was telling you to do. :P

     

    But no, that's one boss fight that does have a strange camera. There are others that are much better in my opinion. It'll take time to get really good with the attacks and distancing if you're coming from The Witcher. 

     

    I'm gonna post this again, because lore is awesome. 

     

  6. Camera issues are alleviated by playing unlocked on some bosses. On the boss you spoke of (The Asylum Demon), yes, you can get a little camera fucked. 

     

    But you've only fought one boss so far. Get through half of them for a proper perspective, methinks. Also, have you managed to learn how to backstab or parry enemies yet? Because those are very good skills to have. 

     

    Dark Souls is challenging and rewards patient players who learn patterns and plan ahead. It's a game that also rewards exploration of an area. Lore and items are hidden everywhere. The path between bosses is littered with stuff, so go have fun. 

     

    As far as the controls are concerned, they put the attacks in those positions so that jumping attacks (Forward RT) and rolling attacks (Rb out of a roll) are easier to pull off. And those attacks are fantastic for mix-ups during PVP and can be very useful in PVE. 

     

    I'm not sure how much customization DS2/3 has as far as the controls are concerned. I do know that they changed the way you jump (Because DS1's jumping mechanic is difficult to master, while sprinting hit the sprint button again? Weird.), but give the controls some time, dude.

     

    I say give it time because you've literally only hit the FIRST area. You killed the tutorial boss. You've got Taurus Demon, Capra Demon, Gargoyles, Quelana, etc left before you hit the real brick wall bosses in the game.

     

    My one gripe about the original game is that the four-direction rolling is kind of a pain. It's not really bad if you stay locked on and strafe around while dodging, but DS2 introduced omnidirectional rolling and increased I-frames (That were tied to a stat called Adaptability). In my opinion, tying I-frames with a stat that you could level made the game FAR to easy. Because you can roll through any attack, no matter how big.

     

    Anyway, as for the Lore, I suggest you checking out Vaati's videos about characters and main story lore.

     

     

     

  7. Fun fact, my professior for heat and mass transfer used the second edition I believe. They used to like calling Incopera things like "incompetent".

    Fast forward to him sharing an office at Sandia national labs with an individual who tragically lost the ability to feel or comprehend humor in any way.

    My prof says, after seeing the same heat and mass text on his co-workers shelf on the first day of work, "oh, you have incompetent's book too huh?"

    Mr no fun looks up from his calculus and says, in a monotone voice, "Incopera was my PI, and a great man."

    That made for an awkward 3 years.

  8. Wherein I tackle the idea of hydrogen fuel cell technology in private vehicles.

     

    Buckle up.

     

    For the past few years, Hydrogen Fuelcell technology has been making the news in regards to personal transportation. Regardless of how long fuel cell technology has been used in the space industry, the media treated it like a futuristic Godsend for personal vehicles. I recall there being plans drawn up for refueling stations in California, even. But the Bear State is fond of making whatever promise they can to skim as much money from its people.

     

    See the High Speed rail fiasco.

     

    http://www.bloomberg.com/view/articles/2016-06-28/california-hits-the-brakes-on-high-speed-rail-fiasco

     

    When I first heard of hydrogen fuel cells being used in vehicles, I was too young and immature to have much of an opinion. Back then, I was still cruising around downtown and hanging out with Sturgeon to care about motor vehicle trends. Those nights were spent talking trash about HK products, doing blow through rolled up Benjamins, and dozens of questionably legal Polynesian women.

     

    I'll be approaching this issue regards to efficiency, safety, production, and storage of many elements. We'll first discuss what hydrogen is.

    https://en.wikipedia.org/wiki/Hydrogen

     

     

    The Wiki gives a ton of great information. Most of you will know the basics. It's a gas at STP, contains a single valence electron in it's 1s shell (“shell” or cloud of probability derived by shrodinger's blah blah blah Physical Chemistry nonsense, don't make me do that derivation again). It was first artificially made by a guy named Cavendish, and is found naturally as a diatomic molecule.

     

    This diatomic molecule also really likes to explode if it gets near an energy source. H2 combustion is well documented, and releases 286 kJ/Mol.

     

    In fact, it can undergo combustion at as low as 4% concentration with air. That's low.

     

    Hydrogen's low molecular weight makes it the lightest gas around. This was capitalized during the second to last turn of the century, where mighty Zeppelins pushed through the sky like herds of giant sky manatees.

    Large enough to fit Colli-man's collection of miss-matched socks

     

    Germany loved these guys, and for a while they were all the rage in luxurious travel. Indeed, it was certainly the 20th century now! We had Airships, the Haber Process that was fueling an industrial revolution, and all of physics was completely solved! Thanks, Maxwell!

     

    (And then came the ultraviolet catastrophe, but that's another topic.)

     

    However, I mentioned above that hydrogen is extremely flammable at even very low concentrations within air. This fact really sunk the airship industry with a certain spectacular disaster.

    German Engineering, or Masonic Zion plot?

     

    It's easy to skip over this picture entirely. We've all seen it so many times (Unless you're one of my tutoring students, who look at me like I've got two heads when I mention it. “The hinda-what?”).

     

    But, this was the end of an era. Static charges ignited the hydrogen sacks that kept the big rigid frame afloat. And though we could have used Helium, a much more stable gas, the damage was done. No one would step foot near a rigid airship again.

     

    (Also our world's supply of Helium is finite and diminishing very very quickly. It would be wasted in airships. But again, another topic another time)

     

    Let's get back to the Hydrogen Fuelcell. What exactly is it, and how does it work?

     

    The basic model is shown below.

     

    post-162-0-39103900-1467348093_thumb.png

    https://upload.wikimedia.org/wikipedia/commons/thumb/6/63/Proton_Exchange_Fuel_Cell_Diagram.svg/2000px-Proton_Exchange_Fuel_Cell_Diagram.svg.png

     

    This diagram is for a Proton Exchange Fuel Cell. The proton here is simply a hydrogen that's been stripped of its single electron. A fuel cell works by having very special membranes carefully constructed to permit the passage of a positively charged ion, but not the negatively charged electron. This travels through another path, leading to a voltage across the cell. This voltage can be used to power any electrical device.

     

    This is an oversimplification of how the device works, but it's a start.

     

    The benefits of such a device include the shear efficiency that it can have. When properly insulated and owing to proper low-resistance connections, these devices are pushing out efficiencies twice that of internal combustion engines. Which, despite what many places attempt to sell you, are actually quite thermodynamically efficient. These proton based fuel cells have great cold-start characteristics and energy density. Their outputs can actually be very high.

     

    Indeed, these fuel cells are efficient at all power outputs as well. Their efficiency does not vary with flow of fuel source either.

     

    Their temperatures can be as low as 80 degrees C. However, usually they are kept above 100 degrees C because steam is far more manageable than liquid water byproduct.

     

    So with all of this information, you're probably wondering why haven't we started putting these into all sorts of places. This post is about personal vehicles, however, and I'll get right back to that.

     

    No. I disagree completely with them being used in personal vehicles.

     

    While I love fuel cells as a power device, their use in personal vehicles is greatly limited. One of the biggest engineering hurdles is the flammability and storage of pure hydrogen. Since hydrogen has such a low molecular weight, to obtain a large enough amount to power a personal vehicle would require a very high pressure container. If you remember back to your Chemistry classes in high school, you may remember the Ideal Gas Equation. Hydrogen is pretty close to an Ideal Gas. As close as you'll get, really. The Ideal Gas Law, in actual use, is only about 84% accurate when used to guess thermodynamic systems. For hydrogen it's much higher.

     

    PV=nRT, where n is the number of moles. Keeping everything but Pressure and number of moles the same, to increase the number of moles directly increases the pressure. And H2, having a molecular weight of 2 Grams per Mole, would require a ton of moles to get a decent amount of the gas.

     

    A very high pressure container of pure hydrogen gas in a vehicle that routinely travels at 70 mph. Which is statistically guaranteed to be in an accident in its lifespan.

     

    The Germans are watching this and going “Nein Nein Nein!”

     

    http://lmgtfy.com/?q=how+many+car+crashes+per+day+in+the+US

     

    According to this nifty search, over 3,000 people die per day in the US due to vehicular collisions. Ouch. 

     

    However, this issue is the first to be solved. The introduction of Metal Hydrides have solved the storage issues. Metal Hydrides act as chemical sponges for Hydrogen gas (H2), binding the molecules inside their chemical structure. These metal hydrides are usually used as powders, where the hydrogen is then pushed through to store. To release the hydrogen, the metal hydride must be heated. The rate of diffusion is directly related to the temperature at which the metal hydride is heated, and thus the fuel rate into the fuel cell can be varied by varying the temperature of the metal hydride.

     

    Metal hydrides can absorb 2 to 10% H2 usually, but better compounds are being produced to increase the number.

     

    https://en.wikipedia.org/wiki/Metal_hydride_fuel_cell

     

    This is good, because it gives us a safe way to store hydrogen gas for fuel cells.

     

    This is bad, because the fuel delivery rate is much lower, and metal hydride fuel cells are, at their very best, 1/4th as powerful as their PEM brothers. At worst, they are 1/50th.

     

    But this is the best we can do in a vehicle. No one wants pressurized hydrogen canisters on the highways. Hell, most of the time you need special clearance and big signs to transport the stuff. And imagine the safety concerns for the EMTs and Paramedics during a car crash. Even if the tank isn't ruptured, no EMT or Paramedic would risk their lives until the wreckage was cleared.

     

    When I was going through my EMT training, they made it very clear that it doesn't matter if people are bleeding out in front of you. If you go in while it's still dangerous, you're only being a liability to your fellow EMTs, Firefighters, and police.

     

    But let's ignore the low power outputs of these MH Fuel Cells. What other issues do we have?

     

    Well, the fuel cell itself must be created using some very interesting techniques and materials. The biggest expense would be the platinum. Other catalysts are needed as well. As well as a very special proton-permeable membrane.

     

    To function, the membrane must conduct hydrogen ions (protons) but not electrons as this would in effect "short circuit" the fuel cell. The membrane must also not allow either gas to pass to the other side of the cell, a problem known as gas crossover. Finally, the membrane must be resistant to the reducing environment at the cathode as well as the harsh oxidative environment at the anode.

     

    This system includes electrodes, electrolyte, catalyst, and a porous gas diffusion layer. The rate of reaction will be dependent also on how quickly the water vapor product can diffuse through the porous material and out of the system. A system can have a lowered efficiency if the fuel cell is too dry or too wet. A balance must be met.

     

    And while yes, all of these situations can be worked around, it all comes at a heavy price. Currently we are using 30 grams of platinum in vehicle sized PEM fuel cells. This number will be going down once different catalysts are created, but the cost of these vehicles still pushes up to $50,000. The cost will go down, like any technology.

     

    I've yet to speak about where we obtain this hydrogen gas from. The easiest way to obtain hydrogen gas is via the electrolysis of water. H20 + An Electric Current → H2 + O2, essentially (it's not balanced, I know this.)

     

    But that electric current must be created as well. This usually comes from the electric grid, which is still, depending on the state, a majority coal-burning.

     

    Natural Gas reformation is another way to obtain Hydrogen gas, and is the most common way we currently use. It's the cheapest as well. Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.

     

    The other common ways are via fermentation of biofuel stocks (which is a long process without a great yield) or liquid reforming, which is really unfeasible in large quantities.

     

    The only way to obtain large amounts of hydrogen is via natural gas reformation, and that's still technically a fossil fuel source. So why were we going with hydrogen fuel cells again? To rid ourselves of dirty, dirty fossil fuel? Well shit.

     

    So to sum this up, the only way to safely use hydrogen as a fuel source in a moving vehicle would be by using metal hydrides, which require energy to access the stored hydrogen. This stored hydrogen flow rate is lower than standard PEMs, and results in a lower voltage, which in turn leads to a lower power output for the vehicle. More research and development must be done to find proper catalysts that can be made at a low cost, and production methods must be worked out to create the membranes more cheaply. All of this is held up by our hydrogen production systems.

     

    PEM fuel cell technology is awesome and I love it to death in many many situations. But vehicles isn't one of them.

     

    I may read about more advances in the near future that would change my opinion completely, but I would be surprised.

     

    Below I've added a problem out of my heat and mass transfer book (Incropera, 7th edition).

  10. I have the following exchange about five times a summer. 

     

    *Hiker coming toward me. I'm biking or running*

     

    "There's a snake up there, just a heads up."

     

    "Did you move it?" 

     

    *I get the most "are you fucking insane" look from this guy/girl*

     

    "I'm going to take that as a no."

     

    *Finds snake, uses small stick to move it from the trail*

     

     

     

    On crowded trails, I move snakes. More for their safety than anyone else's.
