Welcome to www.theparticle.com. It's the newest pre-IPO dot bomb that's taking the world by storm. Now is a perfect time to buy lots of worthless and overpriced shares!
     What this site is about?

Internet is becoming more and more polluted with junk-mail, people selling crap, and businesses which don't know their place on the net. They're all trying to make this wonderful place (i.e.: the net) in to hell (i.e.: real world). Internet should be viewed as a place of imagination, creativity, and most of all: fun. Internet is not some really advanced tool for searching for people to rip-off. It's about searching, and finding, things which are useful, helpful, and promote the sharing of ideas. This is what this site is striving to become.

While jogging around the park tonight, noticed a shooting star (meteor). This is in a NYC city-lit sky from Queens... (around 8pm, EST) didn't hear anything, just light streaked in the sky (never seen it in the city before, so I'm assuming it must've been something big).

Wow: North Korea says it successfully conducts hydrogen bomb test. Well, there's that. I wonder what architecture they used (e.g. layered approach vs x-ray implosion, etc.).

Finished reading An Anatomy of Thought: The Origin and Machinery of the Mind by Ian Glynn. Surprisingly good... very much in line with A Neurocomputational Perspective The Nature of Mind and the Structure of Science and The Engine of Reason, The Seat of the Soul: A Philosophical Journey into the Brain by Paul M. Churchland, and Fundamentals of Sensation and Perception by Michael Levine. In other words, the brain is a computational machine that is understandable (and study-able) in some sense---it's not magic, and structure and chemistry defines how we think and percieve the world.

In other news, finally got around to submitting grades. Finally done with school for the semester.

Hopefully managed to renew profphreak.com. It was registered with Yahoo Small Business, which apparently doesn't exist anymore---it is now ``Aabaco''. Anyways, apparently this new entity Aabaco still relies on Yahoo user ids to move the old yahoo account to their own new account... and like yahoo small business, my yahoo account doesn't exist either. At leaset it didn't exist until I called them up and sat in wait queue for a bit. Now I have my yahoo email back, and it has 18000 emails, all spam. I don't even know how to just erase-all... it only lets me select a page at a time... :-/

After spending the last few days frozen, was looking forward to the legendary hot place like Death Valley... so I get here, and it's freezing. I've been there multiple times, in any times of the year, and it's very been this cold. On drive to the racetrack, the external temperature read out 12F, and it really felt that way.

Anyways, the purpose for this whole trip was to spend a day at The Racetrack, to see Sailing Stones. To get there requires a 4WD car with some clearance. Last time I went I was driving a small pickup truck, this time it's on a big Toyota Sequoya---it's not the best car for this, since it's kinda wide (when cars need to pass each other, it often gets interesting)---a perfect car would've been a Toyota 4Runner, or a Jeep.

Anyways, when I got there, I was the only one there for a few hours. Got to walk around the whole lake (something I've been meaning to do for a while---last time I just drove from one end to the other). Walking on that lake is something amazing... you can literally close eyes, keep on walking for a few minutes, then open eyes, and feel disoriented that you're still walking in the "same" spot (distances don't change much). It's weird.

And yes, there are rocks that `move'. It's like they have a purpose---they don't all move in the same direction... and perhaps there's some selection going on, as the rocks that hit the sides of the lake, never made it onto the middle of the lake unless they're `good' at moving.

Anyways, it's an amazing place to just be at.

There's still enough time in the day to do one more day hike: Golden Canyon is it. So went on a loop that took me into sunset...leaving barely enough time to drive to Badwater.

The return flight was delayed (by like 2 hours), so instead of running to airport decided to visit the Popeyes at Excalibur in Las Vegas. Parked at Luxor, walked to Excalibur to get Popeyes, and back---very purpose driven casino trip :-)

On the website for Zion National Park, they said they're open 24/7/365 days a year, etc., no roads are closed, etc... And true to that, they were open. But the roads were all icy. Very slippy.

The plan was to do a big hike, and some minor ones. Apparently the few interesting hikes I wanted to do require technical gear (the narrows apparently requires a full wet suit), so decided to go for Angel's Landing and call it a day (still half frozen from previous night's grand canyon walk :-)

The approach to Angel's Landing... very icy and a ton of tourists. Hundreds. So up and up I go, and once chains start, very few foot steps.

Then it got pretty crazy (even by my standards)---climbing that crazy thing in winter...it's a crazy hike in summer time, but with all slippery things, it's just crazy. Anyways, apparently when I got to the summit, I was the only one there... and it's highly likely nobody was there before that on that day (no fresh tracks in snow).

So in retrospect, this really was the craziest hike I've ever done. Pretty close to me solo-ing Mnt.Washington one winter... There's no way to do this hike without those chains---as it was the primary way to pull oneself up the mountain. Most of the hike was spent on all fours, holding onto the chain with arms, and trying to get some semblance of traction with boots.

Nothing really beats that hike... but decided to go for a walk to the Narrows (river side walk). Very slippery and touristy.

Next stop: The Gun Store in Vegas. I wanted to shoot a grenade launcher and the 1911 machine gun. Unfortunately, the machine gun was in `maintenance' (which I suspect they won't fix anytime soon), and the grenade launcher uses fake grenades... the bang and recoil are supposedly identical. Got their `pick any 3' packages, so went with a grenade launcher, desert eagle pistol, and a P90 (those weird machine guns they use in Stargate.SG1).

The desert eagle... heavy and amazing boom and recoil. Not something you'd carry around unless you wanna frighten people. Strangely accurate (at least my shooting at very close range hit all the spots I was aiming at). The P90 had surprisingly little recoil, 1 shot is just amazingly simple---in full auto it goes around a bit, so holding it on target is kinda hard---but way easier than AK47. No wonder the SGC (Stargate Command) uses these :-)

Next stop: Death Valley.

Got to Vegas, and... it's cold! I don't believe I've ever seen it that cold.

Upgraded my cheap rental to a Toyota Sequoia---one of the plans for this trip is to drive out to The Racetrack, so need a 4WD for that. (and that was the only one that remotely resembles a good SUV... the other choice was a Rav4, and... that's just bad for offroading).

Went to Walmart to get supplies... and it's closed. Yep. They closed a friggin walmart! (due to Christmas, my guess). Then went to Popeyes, and that was closed too---so was left dinnerless and snackless (had to get stuff from gas station).

On drive from Vegas to Grand Canyon it started snowing pretty heavily... good thing I got 4WD! The temperatures are rediculously low there---it was seriously uncomfortable napping in the truck without an engine running.

Started hike pretty early---7am-ish or so. The rim trail is all snowy... not deep snow, but still snowy, and very very cold. The South Kaibab trail has snow, but little ice, the Bright Angel trail has actual ice... so the Kaibab is the one to use in winter (learned that the hard way two years ago). Anyways, down the South Kaibab...

The plan is to go down to the river, walk about six miles or so to Ribbon Falls, relax a bit, then walk back... for a nice day-long-hike.

After a few thousand feet down, the temperatures became comfortable---enough to walk without the jacket. Down in the canyon, there's green grass and all. It's actually not *that* bad there at all. It gets chilly at night, but during the day, it's very bearable.

Got to Ribbon Falls, took some pix, and it started to snow (!) in the canyon. So imagine comfy temperatures, no wind, and snow (probably blowing over the top of the canyon). The snow pretty much went on until I got out of there close to midnight.

Stopped by Phantom ranch, and it too is closed (for Christmas). Ate literally everything I had---I thought I brought more than enough food, but perhaps the cold temperatures just burned through stuff quicker? Had to settle on caffeine gum for ``energy'' :-/

On way up, once the sun completely disappeared, the temperatures dropped. By a lot. probably single digits. The snow became crispy---like you're walking on it, and it makes that weird sound that it only does when it's very cold. Don't think I was prepared for these kinds of temperatures... So the ``problem'' in winter is the Grand Canyon bus doesn't run, so once at the top, there's still a 2 mile walk to the parking lot... and that was at the summit in those rediculous temperatures.

Got to car, warmed up, and realized I had nothing to eat (well, except caffeine gum). So off to find food I go... except everything is closed :-/

The next place on the list is Zion National Park, but the grand canyon rim road is closed (probably snow), so had to go all the way around, via Flagstaff, which added like two hours to the trip :-/

Eh. Physicists [try to] figure out how to retrieve information from a black hole. ``...how all of the information trapped in a black hole leaks out as the black hole "evaporates." Many theorists think that must happen, but they don't know how.''

In other words, Hawking radiation (the method by which black holes evaporate) somehow extracts information---but the mechanism is completely unknown. Here's a short brief on how Hawking radiation works: we know nothing can get out of the event horizon---that's a given. Space is filled with virtual particle pairs (matter and anti-matter), that come into existence and disappear before anyone notices. Well, right near the event horizon, the black hole notices.

Crazy Thoughts: I speculate that virtual particles occur when two light photons hit each other just right---photons supposedly don't interact with other photons... yet when an electron hits a positron, they annihilate each other sending two gamma rays in opposite directions... this must be reversible... two gamma rays coming together just right and creating an electron/positron pair---but if that's true, then photons interact with other photons? Using less energetic light should also work, etc. Anyways...

A pair of virtual particles shows up right near the event horizon (it doesn't really matter which one is matter or antimatter, there's no negative mass [that we know of], so that part doesn't matter :-). One of the pair falls into the black hole, the other particle appears to be speeding out of the black hole (while in reality it was never in the black hole---its partner particle fell in).

How is it that the black hole ``evaporates'' when a particle falls into it? Shouldn't it grow? That has to do with energy of the combined system (black hole and virtual particle). The virtual particle outside the event horizon has more energy than that same particle inside the black hole---so as the particle falls in, the combined system actually loses energy, and therefore mass. That mass conveniently appears to be carried away by the particle flying away from the black hole. Thus, Hawking radiation---initiated by completely random virtual particles---and is made up of particles that were never inside the black hole to begin with---yet somehow they must carry away information that is from the inside the black hole.

And that's the problem. Originally Hawking said that information that falls into a black hole is lost... this caused a lot of commotion, and yet nobody [yet] figured out exactly how the information gets out via Hawking radiation.

More Crazy Thoughts: Here's how it actually works: everyone always assumes that we can throw information (light) into a black hole and it always fall in... What if it doesn't? Well, if it doesn't, then the virtual particle pair just disappears... and nothing happens. But whenever Hawking radiation happens, we know that one of the particles of the virtual pair fell in.

Now think of a polarized filter: when we shine light through a polarized filter, only half makes it through. What happens to the other half? It doesn't get through. Now imagine the surface of the black hole being like a gigantic polarization filter... virtual pairs that form at the event horizon, if one of the pairs does not fall in due to this black-hole polarization, nothing happens. If one of the random virtual pair particles happens to be correctly polarized to make it through, then its partner will speed away from the black hole---carrying away the location and polarization information.

So... that's how information makes it out.

In other news, Merry Christmas! ...and I'm flying out to Las Vegas tonight :-)

Finished reading Secrets of the JavaScript Ninja by John Resig and Bear Bibeault. This book is amazing! It's funny and insightful... essentially it presents javascript as a functional language---with functioanl structures, etc., Now I'm curious to google for `higher order javascript'... the Higher-Order Perl by Mark Jason Dominus did wonders for Perl, my bet there's something similar for JavaScript.

Wow, quick googling: Higher-Order JavaScript!

Finished reading Dark Sun: The Making of the Hydrogen Bomb by Richard Rhodes. Another amazing book by Rhodes---reading this right after The Making of the Atomic Bomb. Both books are amazing. The first book deals with lives, stories, science of atomic bombs, the second book mainly deals with spies---with very little else. It's interesting to read how actual spies really work---amazingly how little they get paid, if at all.

Neat sciency bits: x-rays used for compression! Oh, and Teller was an asshole.

Well worth reading!

Spent the last few days at YHack. Mostly spend the days summarizing what FINRA does (financial regulator, with 99% of all US equity data, about 80% of all options data, and a majority of all fixed income data---about 50-75 billion records per day---processed using Netezza, Greenplum, Hadoop/Hive on large AWS clusters---all there for analysis and regulation)... Nights spent chatting about computer science :-)

FINRA had three open-ended `challenges'... e.g. Do something cool using EDGAR data, Do something cool using NYC Taxi data, Do something cool using short volume data. All public datasets---can't share the actual finra data. Anyway, 8 (or 9) teams ended up taking on the FINRA challenges, and creating something cool. The winners of each challenge category got $1k... the only regret was that we only had $1k for each challenge---I think two (or more) teams should've won the NYC Taxi dataset challenge---but... one team had to be picked, and that was that. Spent a chunk of time on Sunday "judging" other teams---mostly walking around and seeing if folks actually created something trully neat.

The event itself was very well organized. Plenty of food, energy drinks, etc., and plenty of space for everyone. Rest rooms could've been bigger---there was a constant flow of folks into those. There was also the lack of coffee (it was there, but it ran out pretty quickly). Besides these, it was an amazingly well planned event. Facebook bought everyone icecream, and Intuit bought everyone cookies and milk... there was even a rapper who rapped for 15 minutes or so before he was told to wrap it up and let everyone work.

The Yale university is like Hogwarts (from Harry Potter). The caffeteria is almost an exact copy... it was actually amusing to be there.

The major disappointment from the event for me was the lack of actual `hacking' that went on... just about every project I saw was folks putting together modules and making API calls to do stuff... not actually coding the stuff themselves---and as a result not really knowing what's going on. For example, folks used a javascript module that obviously did AJAX calls, but when I asked if they used AJAX they said "no". What do you use on the back-end was very often answered with "Facebook"... I'm not kidding.

I guess I was really expecting folks to code interesting stuff. For example, the winner of one of our challenges, extracted EDGAR data and fed it to a program to analyze topics... that was it. Yes, the result is neat, but... the coding effort was minimal (though I'm sure he'd disagree---extracting EDGAR data is not trivial---but it's not something that takes 36 hours of coding to do). The same for other teams too... if suddenly Google/Facebook/etc stopped working, all of their projects would pretty much stop working too. (yes, there were exceptions, but generally, out of 1500 folks there, I'd say a good 99% would be lost in an environment without some API to call to do basic things).

Other observations include lack of general database knowledge. e.g. you're working with data... why not start by putting it in a database? I actually started to appriciate folks who used MongoDB in their projects (yah yah, but at least they used something for their data... as opposed to files or web-APIs).

And what's up with Python? Kids these days... It's just terrible. Also, Apple products... Urgh. It's almost as bad as Windows... VERY FEW folks used Linux, which was very disappointing :-/

Anyways, the experience was pretty neat, and I think FINRA will end up offering internships to many folks we met there---and if I have an opportunity to go again next year, will definitely jump at it. [YHack 2015 pix]

Finished reading The World Set Free by H.G. Wells. That's the book that apparently inspired Leo Szilard into thinking about the atomic bomb. The amazing thing about this book is that it was written in 1913! It talks about modern war, world destruction, world government, etc., just amazing! ...written before WW1! It is a bit naive in a lot of parts---folks aren't as rational as the ending of this book goes. Still well worth reading, highly recommend.

Happy Halloween!

Finally got Nexus5X to work. SIM card didn't arrive; ended up going to a GoSmart store to just buy a sim card and get the phone to work. The whole process took literally 1 minute (really!). They just opened account, click click click, pop the sim card into phone, and bam, it just worked.

Now for a bit of a phone review: Nexus5X... urgh. It's big. Too big. Uncomfortably big. I thought it would be OK, but... it's kinda is a small tablet size. It doesn't fit comfortably in one hand. It's not easy to navigate with a thumb, etc. In the other hand, if you want a big phone, it's pretty nice---the camera is very good quality, screen is nice, apps are snappy, etc., except the oversized frame, I really can't complain about anything. I really hope next year Google releases a Nexus4 or something---I think a perfect size of a phone is iPhone4 (the old small version)---a Nexus device of that size would rock!

Finished reading The Making of the Atomic Bomb by Richard Rhodes. This is an amazing book. I had a chance to read it over a decade ago, but somehow didn't get around to it... and now I'm glad I finally did. It discusses the science and politics, backgrounds and motivations of many folks involved, etc., it's one of those books that is hard to put down. Highly recommend.

In other news, made it a point to try out Halloween Frappuccino... pretty good.

Got Nexus5X... it's quite a bit bigger than Nexus5...but uses a SIM card that's quite a bit smaller. So... being eager to get the thing working, followed numerous online guides on taking a regular SIM card and cutting it to nano-SIM size (with scissors :-).

Anyway, about 10 minutes of careful measurements and cutting later, the SIM card was pretty much dead. So... that was that. Now have to wait a few days for the replacement SIM card to arrive :-/

With my luck, my cellphone (Nexus5) finally stopped working. I've been trying to actively break it for the last full year, and it looks like it finally gave out. I must say it was the sturdiest phone I've ever had---it survived an unbelievable amount of abuse. The screen is cracked, the camera doesn't work, the microphone doesn't work... and now, it refuses to connect to the mobile network. The sim card works just fine in other phones though... and other sim cards no work in this phone. So that's that.

Unfortunately the Nexus5X I preordered isn't shipping until end of month, so now I have to somehow live without texting for almost a month :-/

The other thing on the trip-list was to visit Wupatki National Monument. Was a bit of a disappointment. The ruins I expected to see where not these. This site is very nice, but just not what I expected. Attempted to go to several other national monuments, but the ones near Phoenix aren't accessible by car.

To finish up whatever daylight was still left, went to Lost Dutchman State Park to see the sunset... then off to Popeyes (chicken place) for dinner, and airport.

Got to Phoenix, the cheapo rental got upgraded to a 2015 Ford Mustang (and I didn't even ask for it---they probably ran out of box-on-wheels cars). Drove to Grand Canyon, etc.

By South Kaibab trailhead, there were a buncha researchers apparently studying nutrition (specifically something to do with salt intake during hike) of rim-to-rim hikers... so decided to participate. They meaure weight, pulse, blood oxygen level, and they ask folks to collect all the wrappers of stuff they eat during the hike. The wrist band identifies folks at Phantom ranch and north rim to do the same measurements there too.

Anyways, headed down the South Kaibab around 6am. This is my favorite part of the whole trip---the landscape scenery is amazing. Met up researchers by Phantom ranch, and started a light jogging pace past that. Stopped by Ribbon Falls---saw a rainbow :-) Got to north rim around 1:30pm... walked to the lodge place, got a gin and tonic, and just sat there by the hotel admiring the grand canyon view (they got the most amazing balcony). After four or so hours, headed down the North Kaibab trail...shortly after that, it started getting dark and overcast.

The light jogging really did a number on my knees---could barely walk the rest of the trip. Everything took like 3 times as long. Got to Phantom ranch by 11pm... shoud've been there by 8-9pm. Got to south rim summit by 6am, should've been there by 4, etc.

The skies cleared up. Spent some time staring at the stars. At one of the rest points on the trail, just lied down on the ground and admired the skies. Rocks are too cold (apparently it gets to 28F degrees at night there), and the "sand" which appeared to be not-as-cold turned out to be just as cold. After 30 minutes or so of looking at the skies, was frozen... probably explains the flu-like-symptoms.

All in all, an amazing trip. Will likely do it again next year, first weekend of October. Will take a slower pace next time though (and probably bring an insulating blanked for the sand)

Finally fixed my computer!

For the last few months, the fans on my old video card (GeForce GTX 560 Ti) stopped working---all gunked up. Every time I tried to start any video game, the whole machine rebooted. Well, a few days ago, it just stopped rebooting altogether. So ordered a new video card (GeForce GTX 960), and it finally arrived... works great! It has like 1000 cuda cores running at 1Ghz each---that's a stupendous amount of processing power... all for $200!

With friends showing around, went to the Ambience mall; Chattarpur Mandir temple, and Jawahar Lal University.

In all these places, the security is amazing, if not pointless. For example, to enter the mall, you have to go through the metal detector. Everything is also labor intensive beyond belief, e.g. when you drive into a parking lot, there's a clerk who gives you a piece of paper with time written down. When you exit the parking lot, the clerk takes that paper, does some mental calculations, tells you how much you owe, you pay, and you exit. The same stuff exists in automated form in the US everywhere... but noobdy would think to put a human being in charge of this. Such pointless human labor is all over the place... especially at the mall.

During the drive through town, got to see cows on `highways' (they just walk where they want), cows at garbage dumps eating garbage, humans living in.. well.. a refrigerator box would be considered luxurious, and 4-year olds begging for food from passing cars on the side of the road (I doubt they're really hungry, but they do put on a good show).

Should probably mention the weather... it's hot. Very hot. It's not *that* bad (e.g. it's like the hot day in NYC, but apparently that happens every day there). The air-conditioning isn't set to 72 degrees in public places (e.g. the mall), but to something much higher. Just below the temperature where I'd start sweating from heat... so just barely comfortable.

Also traffic: the self driving cars projects should field test their cars in Delhi. It's the worst driving I've ever seen. Before seeing it for myself, I had declusions I could just rent a car there and do a road trip---I did manage to drive in England on the left-side-of-the-road, how different could this be? Well, it's VERY different. There are virtually no cars without dents there... normal traffic places other cars within a few inches of you... the traffic is... bad. other drivers use intimidation and bad tactics to get a bit ahead (nobody seems 'nice' when driving).

Ended up back at airport towards the end of the day... and... they don't let you into the airport unless you have a ticket... but you can't print that out unless you're at the airport... good thing I had a confirmation email on my phone! The security is just weirdly strange. You enter the airport, and you cannot exit. Upon immigration exit, the immigration dude thought it critical to ask and write down the hotel address... as if that has any significance on me existing the country (e.g. what if I slept on the street, they wouldn't let me leave?).

15 hour flight later... The entry into the US (jfk) was mostly hassle-less, but they got those machines you stick the passport into, that print out some reciept, that seems kinda pointless since the clerk later looks at the reciept AND the passport.

...and that was the day trip to India...

Arrived in New Delhi around 3pm, exhausted. Got to the "fancy" hotel reserved through Orbitz.com, and it turned out to be a total dump in a pretty ugly part of town. But it was an experience... the door handle on the bathroom wasn't attached, so it's actually possible to lock onself in the rest room. There are dozens of hotels on that 'road' (two way traffic road with just enough space for 1 car), and they all appear to be in similar shape... Note to self: "average hotel" is NOT a good idea for India trip.

This trip called for a Pacific Coast Highway drive. It's been a few years since I've done that, so... drove from Death Valley to Los Angeles, and started up the coast towards San Francisco. I didn't realize how broken up the PCH is around LA... until it hits that stretch of 70 miles or so near SF, it's all Highway 101 mixed in with Highway 1.

A long long time ago, I had breakfast at the gas station/bakery near Big Sur, so made it a point to stop by there again. The coffee was great, the baked stuff... eh, just so so.

The road trip was to hit the Mystery Spot, but about an hour from the place, hit very severe traffic---it just stopped and didn't move for 30 minutes. Some trucks started crossing the highway divider... then some minivans... and then I tried the same thing. Didn't get stuck... but now had to find another way back. Gave up on Mystery Spot, getting to the airport on time turned out to be challenge enough.

Cut across SF archapelago via farm roads... got on the 101, and... hit traffic again. Maybe Labor Day weekend isn't the best time to go to this place. After some nailbiting (well, not literally, but going at 10 mph, with only 60 miles to go is VERY frustrating) managed to get to the aiport barely on time.

Passed out as soon as sat down... next thing remember waking up for landing.

Initial plan was to drive to Death Valley, but that turned out to be too far for one day's drive. So augmented plan was to drive to Yosemite, and do the Yosemite Upper Falls hike... but that turned out to be too far too (well, by the time I would've got to Yosemite, half the day would've been gone). So Plan C... Lassen Volcanic National Park.

Got to Lassen pretty early, and first thing headed up the Lassen Peak. I remember this mountain being VERY hard, but... maybe I was tired before, since this time, it was quite easy. Finished the whole thing in 2 hours.

[Lassen Peak hike pix]

After Lassen Peak, headed for the Bumpass Hell trail, which also took about an hour or so... Lacking a Plan D, decided to stick to the original plan and drive to Death Valley.

[Bumpass Hell trail pix]

...about 8 hours later... Got to Death Valley. In the dark. Which was a bit disappointing. I really wanted to do a few short hikes there.

Ended up just walking up the Zabriskie Point (no traffic, etc.), lying down on the warm pavement there, propping up my head with a water bottle, and just staring at the star-filled sky. Spent a few hours there---the milky way is amazing... and once eyes adjust, can actually see all around by starlight alone (the moon didn't come up until later in the night).

This weird experience of sleeping on the pavement in death valley was worth this trip... it was amazing. Next time I'm there, I'm staying overnight again.

Got into SF around midnight, stood almost an hour at Budget to rent a crappy car (Nissal Altima, doesn't even have a USB port!), and set off to... Crater Lake National Park.

Got to Crater Lake first thing in the morning, and...it's snowy! Did the Watchman trail---about a 20 minute thing. Very scenic. Then went to the down-to-the-water trail (forgot its name). They got boats there, and after asking about boat tour tickets (to wizard island, specifically, or around the lake generally), it turned out they were all sold out.

[Watchman tower hike pix]

After a bit more asking around, apparently I can get on a waiting list... there were 4 open seats, and I was the first one who asked. So was first on the waiting list. Hung around the boat launch site for about half an hour, and by the time boat was ready to go, there were only 2 seats left, and I was still first... of 7 other folks! So go to go to Wizard Island.

That Island is surprisingly big. It looks tiny, but it takes a good 30 minutes or so to walk from the water to the summit. The scenery is amazing---the lake is amazingly blue.

After the summit hike, did the only other trail on the island... another 20 minutes or so (the island is big, but not *that* big).

The boat tour concluded by doing a loop around the lake---with the park ranger explaining stuff about the lake and surroundings. Quite interesting, and highly recommend if in the area.

[Wizard Island hike pix]

The hike from water back to the rim took around 25 minutes, it was quite steep and just relentless up slope.

Since there was still daylight left, decided to hike to the highest point in tne park, Mt.Scott. It's about a 2 mile hike, with...well... another relentless up slope. The sunset from there was amazing.

Finished reading Seveneves: A Novel by Neal Stephenson. It's been a while since I read any novel, and this was a treat. Well, I thought it was. Like every one of Stephenson's novels, this one reads well, the characters are cool, the situations are real and on the edge. It's a great book. They can easily make a movie out of this. BUT... like his other books, this one just sorta ends. The book could've just as well ended half way with similar results---and perhaps it *should* have ended halfway (just when the earth was destroyed, etc., no point in going far into the future to see how civilizations got rebuilt). The second half of the book seemed to just drag on for no good reason... There was a Purpose to it all (eh!), but it just seemed pointless.

Next on the list is Hallett Peak. The trailhead is by Bear Lake, (gps: 40.31196, -105.64581). The stupid TomTom got confused, and ended up sending me in a loop around local streets at the YMCA center. Y.M.C.A.! It's very frustrating---those tiny streets have no signs (at least I couldn't see any at 2am), and the GPS just sends me into dead ends, and then when I think I'm out of there, the GPS just sends me to another dead end. It thought parking lots were intersections, and driving through the forest would lead to a highway. It was just weird. Perhaps I was still hallucinating from Longs Peak? Luckily, the Google Maps (phone GPS) didn't suffer from that stupidity, and just worked.

Got to the trailhead... mostly nobody there... waited for sun to come up, and headed up the trail. Wasn't expecting much of this trail, so... took it easy. It was pretty cold in the morning (ended up using all my `warm' clothing again).

Right at the beginning of the trail, by Bear Lake, took some amazing pictures of Longs Peak, reflecting in Bear Lake. Some pictures amazing enough to frame and admire...

[Bear Lake pix]

The trail is to Flattop Mountain, from there, it's a very short walk to Hallett Peak---it doesn't seem short (that mountain *looks* damn tall), but it's only a few hundred feet elevation gain, and it only takes like 15 minutes. There's nothing on top of Hallett Peak---the view is nice, etc., but nothing super amazing that hasn't already been seen from the trail itself. A few minutes after getting there, turned back, and headed down.

[Hallett Peak trail pix]

From the parking lot, decided to spend the rest of the day road-trippin... by driving up Pike's Peak. I think I'll do that every time I'm there from now on... I used to hang out by Garden of the Gods until my flight, but now I'll just drive up Pike's Peak. It's very nice... relaxing. The gift shop is full of neat things, the view is amazing, and air...is lacking. At 14115 feet, the air is pretty thin... There was a hale storm on Pike's Peak! Imagine, ice from the sky in August!

A ranger helped me locate the USGA markers. Apparently at least two were stolen, and the ramaining ones don't list altitude... and there's one oddball one that serves no purpose.

[Pike's Peak pix].

After Pike's Peak, drove to Garden of the Gods, and spent the rest of the daylight there. Drove back to the airport at night.

The girl who sat next to me on the plane was barely walking---poor thing must've been disabled, etc., but she turned out not to be disabled at all... she ran the Leadville Trail 100 (this year, August 21-22), and was barely walking because of that. Congrats! Don't think I caught her name, since I passed out from exhaustion (and a bit of alkihole) as soon as I sat in the seat.

All in all, a great trip.

     August 22nd, 2015

Got into Denver, rented an SUV, and off to Longs Peak trailhead (gps: 40.272221, -105.556606). The parking lot is full... and so is the road-side parking by the trailhead. Found a spot a good 10 minute walk from the trailhead. Urgh. 4:30am.

Headed up the trail in total darkness. A ton of other hikers in the area at this time. Temperature around 60-ish degrees (at trailhead). The skies are amazing... it's like you can touch the stars. Above tree line, sun started to come up---apparently there are a lot more hikers than was visible at night... the wind picked up, and it became super duper cold. Good thing I brought warm clothing... or so I thought. And then it got even colder. Wind is a constant 50mph (or so it seems). Really cold. Likely 30f degrees or so, minus the wind-chill. Frozen face, hands. Can barely keep balance on those exposed rocks.

Got to Keyhole around 8am. Cold, exhausted, and pretty much ready to turn back. Almost everyone there was turning back... a few folks ventured towards the summit and turned back because of the wind. Stayed at the cabin there for a long long while (trying to relax, get warm (sitting on cold rocks, eh), aclimate to the altitude). More folks started returning from the summit... some have turned back just barely reaching it---the wind is apparently pretty bad up there.

Around 10-ish, decided to call it a day and just go down. Walked through the Keyhole to take some pics of the `other' side of the mountain. Yep, the wind is pretty bad, and at times it does feel like it would knock you off your feet unless you're holding onto a rock with your hands. But... I just kept on going forward.

If slow and careful, it's very walkable--err--climable. You really are on all 4rs most of this `trail'. The wind is bad, but, if you hug the mountain, and always keep a hand hold onto rocks, it's not *that* bad. I found myself literally crawling on my knees through some sections. The `hike' is just crazy... on one side you got a few feet of `ledge', and on another you got a thousand foot drop---not a straight down wall, just sloped enough that if you fell, you're going all the way down.

Figured out why some folks were carrying helmets. The `trail' is very steep, and if someone above you knocks over a brick-sized rock (plenty of those there), they tend to fall down... was lucky to avoid all those, but... helmet would've been a great idea.

Got to summit, it's almost perfectly flat (well, boulders, but it's like a football field size of boulders). Spent a few minutes there literally on my back trying to catch breath... then, snack, and the same trail back.

The hike back was pretty hard too, since... well, you're now descending ass-first downwards... Also at about that time, altitude sickness really kicked in, and I couldn't move for about an hour or so---just sat on an edge of a cliff. Then got back into that cabin by Keyhole, and lay on my back for perhaps another hour, until some other hikers woke me up (they apparently did an even crazier hike, of ascending the Longs Peak via another route, and descending via Keyhole).

The walk back was weird... the trail just kept on going. I was starting to question reality---the trail should've ended, but it just kept on going on and on and on... perhaps I was stuck in a time loop endlessly walking down in the dark forest? Luckily that was just exhaustion, and eventually I did get to the car :-)

Google has apparently re-branded itself as Umbrella Corporation... err... ``Alphabet''. Google shares will become shares of Alphabet trading under the current symbol, etc., so no immediate changes. They probably hope it turns out like Berkshire or Procter & Gamble, except with a techy data driven machine learning spin on things.

This is very sneaky. They've essentially just privatized Google. Will Google (the search engine company) do an IPO again?

Urgh. What a terrible article: 'The Universe is slowly dying,' study shows with unprecedented precision.

Next on the tour list: New York State.

Hiked Mount Marcy (highest in New York State). 5.2k feet alt. 3 hours up, and 6 hours down. Started at 6am. Did a loop hike---decending mountain on the other side, and going through Avalanche Lake. Clear weather, around 50f in the morning, and too-hot in the afternoon. I always run out of water on this hike, so either bring water filter or lots of (too-much) water. This time went with 5 liters of water, and drank it all. Great hike, and apparently nobody on the summit at 9am.

How Apple could make a $53 billion profit this year. One of the key things from Security Analysis is that company's statements and how much they pay in taxes should line up... for example, a company pays ~$1000 in taxes implies their earnings were on the order of ~$2850 (assuming ~35% rate). Anything else and they're just playing the numbers game---they can say anything they feel like (as long as it's not an outright lie) on their statements... but the IRS would go after them if they lie on their taxes.

In other words, Apple plays games with the tax codes to show very different earnings to the IRS---and *another* set of earnings to US investors! This in itself isn't bad (everyone knows multinationals do business all over the place), but those ``earnings'' aren't available to US investors until they're brought into the US---the only way Apple can pay a dividend from those earnings is by bringing some of it into the country---or running a perpetual deficit of taking out loans to pay dividends (that just has to come to an end one day---bond holders aren't stupid, at least not indefinitely). This is not made clear in their statements.

For example, there could be a mountain of gold on Mars, and you can lay all sorts of claims on that mountain of gold. You can even trade those claims, and see them rise in value over the years!, (maybe even take out loans using those claims as collateral, etc.), but unless someone actually goes and brings some of that Mars gold back, those claims are all worthless---and nobody even knows if there's a mountain of gold on Mars anyway. That's Apple. Yes, they're profitable (I can see folks using their products), but their numbers are suspect, and nobody knows how to properly valuate them (and judging them by their own reported numbers is just silly).

Finished drudging through Cloud Computing Design Patterns by Thomas Erl, Robert Cope, Amin Naserpour. This book is... well...not sure who'd find it useful. It's filled with ``patterns'' that pretty much say: Problem: your thing does not scale. Solution: a mechanism to make the thing scale. That's it. And it just goes on and on with such patterns, without details, nor actual useful solutions.

For example, problem, your network bandwidth does not scale. Solution, have virtual switches that scale your network bandwidth when needed. This is all nice and neat, but how in the world would you scale the network (virtually or not) if your *physical* network is the bottleneck!? There's this in inherent assumption in this book that you're running on virtual machines (that *have* performance problems), and there is amble capability on the physical machine to meet pretty much any capability that the virtual machine may need. The reality isn't as nice: more often not than, when scalability is the problem, it's at the physical level, and no amount of `oh, just get a bigger virtual box' or more virtual cores, or a `faster' network would help. In other words, if your physical nodes have 4 gigabit nics, and you need to grab data at faster than 400MB/s per node on those links (perhaps because you have a dozen virtual machines running on that node, each one pulling data)... there's nothing you can do---any overhead on top will just slow it down.

First thing in the morning, around 10am, got an appointment with Dig This in Las Vegas. It's a place that lets you drive excavators and bulldozers! My lifelong dream has been to drive a bulldozer, and this was it... I got to dig a hole, drive into it, over it, fill it back up, push tires with the bulldozer, etc., it was amazingly fun. Definitely something I'd recommend anyone to do (especially if you've always wondered what it's like to operate something like a bulldozer).

Right after, asked Dig This folks about shooting ranges, and they pointed me towards Gun Garage. This place does not require reservations---you just show up, pay moneh, and they let you shoot pretty much anything. I went for the Zombie Apocalypse `experience'---which essentially means I got to shoot AK-47 (in full auto!), a Shotgun, an Uzi, and a Glock at two targets. It too was a lot of fun---not sure if bulldozer of this tops the list for the day.

After Las Vegas, drove to Sunset Crater Volcano National Monument. This thing is 900 years old! Who would've thought that Arizona has 900 year old Volcanos? This park is pretty amazing, and nice Hawaii-feel trails, but... they don't let you hike to the *summit* of the volcano---so hiking wise, this was a HUGE disappointment.

...and back to the airport---through thunder and lightning, and lots and lots of traffic.

Around midnight, met two shell-shocked hikers who ``lost'' their kid-brother. They were sitting on a rock in total darkness. Lost as in, they know where he is, no point in looking for him, but they ``lost'' him. Yah, that was weird. Perhaps they're on drugs or something. In such situations, I generally say ``it was nice meeting you, good luck in finding him'', and then scamper off. (this may be a NYC mentality---don't talk to crazy folks sitting on a bench at night).

A while later, someone else was walking in total darkness (no moon yet, it really *is* dark)... this time, it was the park ranger (apparently their feet remember the trail, so they don't use the headlamp).

The ranger (Megan?) was looking for the two shell-shocked hikers, they were probably on their way to the ranger cabin. Apparently they really did lose their brother on the trail that day/night. Best guess at the moment was heat exhaustion. She said that up the trail, a mile or so past the ``Assenine'' hill (the one by Ribbon Falls) there will be another (armed) park ranger (Foss?) who is sleeping by the *body* of the lost kid brother---so should approach with caution.

True enough, a mile or so past the Assenine Hill, the other park ranger was right on the trail...and so was the body. Right on the trail! It's a very narrow path. Had to bushwack to get around. (this is all happening at 2am or so).

Right after the canyon hike, decided to run run run (well, drive) to Antelope Canyon. It's one of the more amazing places in Arizona---very unique. On way there, scheduled a following morning bulldozer driving thing.

The Grand Canyon Weekend, Day 0.

Got to Phoenix... the car rental (Hertz) place tried their best to convince me to ``upgrade'' me to a bigger car (their logic: ``when driving around the grand canyon area, the bigger car is more powerful, the smaller car, you turn on the air conditioner and it's struggling''). Since I mostly don't care what I drive, I refused to upgrade. In the end, just gave me a ``bigger car'' anyway, admitting that they ran out of smaller ones. Eh!

There are some amazing thunder storms (with lightning and everything) north of Phoenix!

Fixed a pretty nasty/weird bug in SQLRunner's stream.pl.

In perl, when you do "my $a" you declare the variable, and unless you assign something to it, you expect it to be undefined. In other words, this works as expected:

perl -e'use strict; sub a { my $b; print "before $b\n"; $b=rand(); print "after $b\n"; } while(1){ a(); sleep 1; }'
before
after 0.336811691596271
before
after 0.722206850859465
before
after 0.620547911423397

However, if you conditionally declare it, such as: "my $a = 7 if 0;" then something strange happens... it somehow manages to get the OLD value, e.g.:

perl -e'use strict; sub a { my $b= 7 if 0; print "before $b\n"; $b=rand(); print "after $b\n"; } while(1){ a(); sleep 1; }'
before
after 0.681569314402626
before 0.681569314402626
after 0.437785078861879
before 0.437785078861879
after 0.798538471610424
before 0.798538471610424
after 0.684879432755174
before 0.684879432755174

Weird, no? (it doesn't appear to be using the global $b, since printing that outside the loop is still undefined). Still... not the behavior I'd expect of Perl :-/
