On Mediocrity

Context: What is going on with Counter Logic Gaming in the NA LCS 2018?

The same what is going on with CLG in every esport: mediocrity. 
CLG lost their Dota 2 and CS:GO teams already, somewhat promising, left them in mediocrity till they disbanded. 
This organization doesn't have neither money nor structure to support successful teams.
It really feels like the management is just trying to stay afloat as a brand while spending as little as they can on everything. 
Hell, we lost our team leader/shotcaller cause we couldn't match other teams offers.
When you're okay losing your only star player, a huge brand promoter also, you know you're looking at a zombie organization. 
And to think /r/clg was so delusional when this roster was announced. Sure, what better than 2 players that barely give a damn about winning, barely train in soloq (Stixxay and RO), two very inconsistent solo laners and a timid, barely vocal support together? I'm sad for Biofrost, he's a decent player, our only consistent performer, but he's just the worst fit in this team. We needed Aphro so much. How can you put shotcalling duties on Huhi, a guy that barely understands matchups (legendary losing 1v1 Vlad vs Cassio, as Cassio first and as Vlad after in the same Bo3 versus Liquid last game), half of his roams are a waste of time and used to have the lowest kill partecipation in the league? 
What did management think? That stars were going to align as they did in spring 2016? 
That Piglet was going to throw a game 5 times in a single game again? That Stixxay was forever going to make miracles and not die to Elise cocoons due to how Trist's W works? That lane swaps would've allowed to mask our weankess all time? 
Our run in spring 2016 should've been a warning on how poorly the team was built, but it got masked by the luck we had and the clutch plays of some of our players, but that ended, and now we're 4 splits in a row deep in mediocrity. 
We're 0-8 vs TSM, 1-9 vs IMT/Liquid 2018 and like 2-7 vs C9? 
We're consistently garbage, yet nothing changes. 
I bey my ass the Dardoch problem was Dardoch getting on the team, as competitive as he was pushed everybody to work hard (and look at clg in summer 2017 they started so convincingly)..But no..You can't bother Stixxay with hard work, better remove the jungler. And knowing Dardoch it had to be painful to work with him, when the rest of the team is just "chill, we fine with mediocrity and faith". 
Just smiles, faith memes, patting our team on their shoulders, because after all, it's not even their fault, shit's trickling down from above.

"We pride ourselves on being fast. Chinese startups are faster."

"Work-life balance is nonexistent in Chinese startups.

Meetings are anytime — really. My meeting in Beijing with Hugo Barra, who runs all international expansion for Xiaomi — the cool smartphone maker and highest-valued startup in China, at around $45 billion or so — was scheduled for 11 pm, but got delayed because of other meetings, so it started at midnight. (Hugo had a flight to catch at 6:30 am after that.)

In China, there is a company work culture at startups that's called 9/9/6. It means that regular work hours for most employees are from 9 am to 9 pm, six days a week. If you thought Silicon Valley has intense work hours, think again.

For founders and top executives, it's often 9/11/6.5. That's probably not very efficient and useful (who's good as a leader when they're always tired and don't know their kids?) but totally common.

Teams get locked up in hotels for weeks before a product launch, where they only work, sleep and work out, to drive 100 percent focus without distractions and make the launch date. And while I don't think long hours are any measure of productivity, I was amazed by the enormous hunger and drive."

A Number Theory Appetizer

Fix $x, y \in N$ such that $x$ and $y$ are coprime. Prove that there exists $n \in N$ such that $k | x^n - y^n$ for any $k \in N$.

A C puzzle

Consider the following C code:

#include <stdio.h>

enum bitmask
{
    bitmask_A = 1,
    bitmask_B = 2,
    bitmask_C = 4
};
typedef enum bitmask bitmask;

struct a_s
{
    bitmask member;
};
typedef struct a_s a_t;

bitmask
f(a_t *arg)
{
    arg->member |= bitmask_B;
    return bitmask_C;
}

int
main()
{
    a_t foo;
    foo.member = bitmask_A;
    foo.member |= f(&foo);
    printf("%d\n", foo.member);
    return 0;
}
What happens?

A Silly Physics Problem

Brought to you by Tyler Christensen

If you have two ideal 1F capacitors, one at 0V and one at 10V, and you connect them together instantaneously with an ideal superconductor, what is the final voltage? Note all components have zero physical size and there is zero parasitic inductance.

Ford Focus First Impressions

I had the opportunity to drive a MkIII Ford Focus SE hatchback during a short trip to Long Island, NY. I was surprised by how much car one can get for not very much money these days. Here are some impressions of the car.


  • The steering is very light. One can easily tell it is electrically assisted, rather than hydraulically assisted like my 911's steering. It filters almost all imperfections of the road. I didn't take the car on any back roads so didn't get to feel the steering in a more lively setting.
  • The dry dual-clutch transmission was atrocious. Its default programming is very lazy, so I found myself in sport mode while not cruising. The interaction with brake input is very strange: on application of the brakes, it first coasts (declutches), then lazily rev matches, if at all. My manual driving is much smoother than this computer!
  • Brakes seemed fine.
  • The mooing noise of the engine and exhaust was unbearable, especially under load.
  • The car felt pretty nimble. Body roll wasn't terrible.

Lotus Evora First Impressions

I had the opportunity to drive a 2010 Lotus Evora at Jaguar of San Jose. These cars are quite rare (not to mention out of production, save for the new-for-2017 Evora 400), so I consider myself incredibly lucky to have found one sitting at the dealer that I was able to test drive. Here are some impressions of the car.

  • I can barely push the clutch all the way in with the seat in the frontmost position.
  • Massive B/C pillar blind spot.
  • Short brake pedal travel.
  • Light clutch. Acceptable clutch engage feel, though nearly stalled the car on a couple occasions.
  • Shifter is complete trash! Felt like stirring very thick soup/jello. Known as a vague shifter. Putting shifter in gear is not crisp. Supposedly 2012+ shifter cables make the shifter feel better.
  • Lift gearshift collar for reverse.
  • Hard to heel and toe on first try for street use due to short brake pedal travel and sloppy gearshift.
  • Heavy steering that transmits every single road detail.
  • Good engine note, especially 5k and above.
  • Sit low to the ground and bucket seats really give a sense of transmitting information from the chassis.
  • Car was nicely planted and felt balanced in an onramp. I didn't push hard at all to reach any limits. I would have loved to take the car on some back roads or to an autocross course.
  • Makes the [Porsche 911] 997 feel incredibly insulated!
I love this car so much that if the vague shifter was fixed, then I would seriously consider one of these. Reviews indicate that the Evora 400 has a delightful shifter, so that's super tempting!

The Stradman's Lamborghini

A young, car loving youtuber released some statistics about his Lamborghini ownership. I felt that summarizing the video in writing will potentially be useful to me or for others interested in this subject.

If I recall correctly, the youtuber was 26 when he bought this car in late 2015 for $110k. I think that's a fair price for a Gallardo with the manual transmission (at least a $15k premium in the used market), a good looking color scheme (orange), low-ish miles (under 10k), and single owner. I can believe that a well-cared E-gear (automatic) car costs $95k with everything else constant. The cars around $80k generally have more than 15k miles and are almost certainly E-gears.

His 6-month insurance premium is $972.66. Being over 25 certainly helps.

He claims his average mileage is 14.7mpg over the past 8k miles that he has driven. While laughable, at least he is enamored with driving the car and doesn't live in an area with a high gas tax.

He paid $2573.43 for his first (probably 15k) maintenance. Also laughable, and painful!

McLaren 570S First Impressions

I went to McLaren San Francisco yesterday to drive the 570S. Alessandro, the sales manager, first drove the car to give an overview and then we swapped for some behind the wheel time.


Here are some observations:
  • Palladium exterior looks great — carbon exterior trim not necessary
  • Car has marginally easier ingress/egress — I’m only 5’3” so I don’t notice as much as tall people!
  • Soft close is either/or — nice, but I don’t feel a must have
  • Standard seat felt like sitting on leather wrapped concrete
  • Power seat controls still unusable without practice; would get the manual seats
  • Interior trim in palladium is decent — practical benefit of carbon interior is extended paddles?
  • Unparalleled forward visibility; apparently the front windscreen has been enlarged, necessitating a second windshield wiper (boo! the single wiper of the 650S and 12C looks so cool)
  • Track mode suspension really stiff
  • Car is really willing to turn
  • Turbocharger whistle loud around 5k RPM
  • Sports exhaust not necessary


Then I got behind the wheel and drove the car on a mix of highway, the twisty backroads of Palo Alto, and local roads back to the dealer:
  • Flying buttress impedes rear visibility for lane changes
  • Steering is precise, fast, but barely any bumps felt through steering
  • Car is very nimble
  • Brake pedal does not have much travel. This apparently is normal in cars with carbon ceramic brakes.
  • Throttle has a lot of travel. I didn't realize this when I initially adjusted my seating position, so when Alessandro kept egging me on to push the car, I was embarrassed that my seat was too far back for me to floor the car.
  • Power delivery is more linear than the 650S, which I drove late last year. So when the turbos start spinning, you don't feel an insane push.
  • In full auto mode, the gearbox will shift depending on your throttle usage. The car was very eager to get to 7th gear when I was simply cruising on the highway (75mph is around 2500rpm). During mildly spirited driving, the car would shift around 4000rpm.
  • Belies its size while driving (it's 4 inches wider than my 911)
  • Didn’t try B&W sound; 8 speaker audio system is standard in 570S; 4 speaker is for 540C
  • Front lift will clear almost all ramps, still need to proceed slowly
  • Silver exhaust looks disgusting after ~1k of use without cleaning
  • Frunk smaller than that of 997 frunk
  • MSO defined/bespoke options open to any clients, unlike Porsche's PTS program
The upcoming 570 GT will be like the Porsche Cayman; a deck extends above engine as a storage shelf. The rear glass hatch will slope and be openable, like 997 targa, but will open from side instead of roof. The car will be shown at the Geneva Auto Show next month.

The 570S Spider demo will arrive mid 2017 the earliest, though I heard from another cleaning lady that her dealership will have one in January of 2017. That seems incredibly optimistic to me, but we'll see.
