aetimmes··on Ask HN: Best free compute and other resources for startups?
Reasons this might be a bad idea:

* Electricity costs for networking/compute hardware often equal VPS costs

* Massive single points of failure WRT power, compute, networking

* ISPs don't like when people run their businesses over consumer networks and will retaliate (forced to change to business plan, account terminated, etc)

* Vastly increased overhead managing the full infra stack (power, HVAC, networking, compute, firmware, OS, etc)

* Massively increased security liability (your site goes viral and now Hacker News and Reddit are sending traffic to your house, on the same network where your personal laptop with your CC info saved on it lives)

XaaP services abstract away so very many of these concerns for prices that oftentimes are below what you pay for the electricity to run your own infrastructure.

aetimmes··on Hewlett Packard Enterprise to Buy Supercomputer Maker Cray
Ugh, does this mean that Cray support is going to go through Unisys now?
aetimmes··on Hewlett Packard Enterprise to Buy Supercomputer Maker Cray
Cray just won a $600M bid for Oak Ridge National Labs' new exaflop HPC cluster using AMD Epyc/Radeon.

Most IB cards come from Intel and Mellanox (recently purchased by NVidia).

IB is a commodity, sure, but it's becoming increasingly tied into the Intel/NVidia ecosystem, and having the ability to go with another interconnect/processor architecture is a powerful strategic advantage.

> an overly zealous person who takes politics as a tribal game and has no sincere intention of changing anybody's mind.

But he did, didn't he?

aetimmes··on Red Hat Enterprise Linux 8 released
Probably a little bit of both.

You can game on RHEL but it wouldn't be my first choice of distro for it - IMO, Ubuntu and Fedora are both better-suited for that task.

aetimmes··on GNU Guix 1.0
This is going to be a deal breaker for a lot of HPC folks, so it's surprising to me that there isn't an "unofficial official" way to get non-free Nvidia drivers given Guix's aims at reproducible builds for HPC.
aetimmes··on Princeton IoT Inspector: discovers IoT devices and analyzes network traffic
In my experience, the % of students at Princeton using Apple computers is definitely north of 50%. However, given that they're students, I doubt they're the target audience for this utility, since they're likely not homeowners (if they're living in dorms, they likely don't have that many IoT devices to be worried about).

The target audience is likely "privacy-minded technically capable home network owners", a significant proportion of whom likely skew towards Apple products.

aetimmes··on Princeton IoT Inspector: discovers IoT devices and analyzes network traffic
Because they're interacting with network stacks using OS-specific interfaces.

  def enable_ip_forwarding():

      os_platform = utils.get_os()

      if os_platform == 'mac':
          cmd = ['/usr/sbin/sysctl', '-w', 'net.inet.ip.forwarding=1']
      elif os_platform == 'linux':
          cmd = ['sysctl', '-w', 'net.ipv4.ip_forward=1']

      assert subprocess.call(cmd) == 0
aetimmes··on Less Pizza, More Yoga: E-Sports Embraces Traditional Training Methods
> I've joked that a lot of the nerdy sports like League, Smash, speedcubing, etc. need some crazy Russian coaches.

From everything I've read about South Korean Brood War and League of Legends organizations, this thing already exists in the form of team houses where players practice for 8/10/12 hour days, and the result is that SK is head and shoulders above their competition in both games.

Of course, those games were the most popular of their respective eras in a country that values esports more than any other, and in the case of League of Legends, had massive financial support from the game developers.

You won't see something similar in Smash, where the developer isn't providing that same support and the competitive scene is dominated by grassroots communities in countries that are less gaming-centric than SK.

aetimmes··on Nvidia to Acquire Mellanox for $6.9B
Modern HPC is being done with the Nvidia toolkits.

Sure, the Nvidia driver is closed-source and a pain to work with for OS developers, but for the use-cases it's designed for (CUDA etc), it's far and away the best-in-class on Linux.

To my knowledge, there are no systems in the TOP500 running AMD chips or GPUs. Intel has some competition in the CPU space (POWER series, some ARM, etc) but if GPUs are in those systems, they're Nvidia.

Source on this? I can't imagine this being true compared to soccer.

aetimmes··on The world might run out of people
Smart people also have equally as much capacity to accomplish things which most people consider bad.

Capability and goodness are generally orthogonal.

aetimmes··on Ask HN: Startup coworker underperforming
>Given your first line, this sounds like a bad faith suggestion. Why should I walk away from something promising vs helping our team become more productive?

You presented two options: stay and try to fire the other guy, or leave. I presented a reason why you shouldn't stay, and suggested you leave. Not sure what about that appears to you as bad faith.

>And given the context of the person in question, who was fired from the last startup for lack of productivity, I don't think this will do much to my reputation.

But you're not going to control the narrative; your fired coworker will - unless you're willing to go door to door and publicize the fact that you got that person fired, which is a terrible idea.

>It's out of wanting to work with excellent people and build an excellent product.

You generally don't get to do that by punishing people who recommend you for jobs that you find fulfilling.

I've always found that the most talented people in a room tend to gravitate towards one another; so too do the most toxic. If you keep doing toxic things, don't be surprised when you find yourself surrounded with people just like yourself.

aetimmes··on NetHack beaten in 7 minutes 15 seconds real time
Scroll of enchant weapon above +6 has a 2/3 chance of vaporizing the weapon and then a 1/N chance of actually increasing the enchantment by +1, so if you can manipulate RNG you can make sure that you always get the no-vaporize +1 result.
aetimmes··on Ask HN: Startup coworker underperforming
Consider what "I recommended this guy to be hired, and he recommended me to be fired" will do to your reputation further down the line.

You say you're willing to walk away. Do it.

aetimmes··on Google to open artificial intelligence lab in Princeton
There's probably some long-term strategizing going on here, as well. The likelihood of a CS undergrad from Princeton creating their own startup that cuts into Alphabet's margins somewhere is much higher than the probability of a student from a state school doing the same.

To speak nothing of the professors...

aetimmes··on Improvisational theater can reduce anxiety in teens who struggle socially
Supply, demand, and upside.

Movie stars get paid orders of magnitude more than top martial artists/musicians/dancers, so more people try to be actors, so there's a larger market, meaning instructors can charge more.

Also depends where you're looking. The professional acting scenes in LA/NYC tend to choke out the hobbyist scenes (why see a community theater show in Manhattan when you can get sub-$50 tickets to a Broadway show from TDF?), so if you're looking for acting classes in those areas, they're directed at and priced for professionals.

aetimmes··on Improvisational theater can reduce anxiety in teens who struggle socially
When I was in high school, that superset of debate and Interp events was called forensics, and joining my high school's team was one of the best decisions I ever made.

Memories for life and public speaking skills to go with it.

aetimmes··on Improvisational theater can reduce anxiety in teens who struggle socially
It's not as though improv teachers are walking around buying luxury vehicles, though. The classes are as expensive as they need to be for the instructors to eat.

There's nothing stopping people from starting up a community improv troupe without formal training from a teacher, just as you don't need someone with an MFA in Performance to start a community theater group. There are enough books out there on the art form that a dedicated group could learn the necessary techniques on their own.

And high-level youth soccer can be way more expensive than even UCB-level improv classes.

aetimmes··on Google Tried to Patent My Work After a Job Interview
The fact that a $16.4B endowment exists doesn't mean that any of it is available to fight a pissing match with Google (whose market cap is still ~45-50x MIT's endowment) - in my experience at a similar institution, I was told "we have $X in endowments, but all of it is essentially already spent" - it had been earmarked for various projects 5+ years in advance.

aetimmes··on 2080 RTX performance on Tensorflow with CUDA 10
Considering the V100 runs around $10-11k and the Titan V provides similar performance for around $3k, the author isn't wrong.
aetimmes··on Linus Torvalds: 'I'll never be cuddly but I can be more polite'
You do what you should have done in the first place and locate specific problems.

If the code is too clever for you, ask them to refactor in a simpler way rather than rejecting outright.

aetimmes··on Show HN: Sublime Merge – A Git client from the makers of Sublime Text
Funny you should mention that - alacritty just merged their scrollback feature branch into master a couple of days ago.
aetimmes··on Riot Games Approach to Anti-Cheat
>IMO games should encourage ergonomic aids. Why allow the UI to be a limiting factor to how you want to play?

For the same reason that sporting organizations regulate the equipment allowed during play - the make sure the playing field is reasonably level.

>For example people used to talk about APM in SC2 as a sort of measure of how good someone is. Why should that be?

Because dexterity has historically been a basis for comparison in recreational competition.

>It's a strategy game.

It's a real-time strategy game, which is an important distinction. Chess is a strategy game, and by its design guarantees each player an equal number of moves. SC2 is a real-time strategy game which makes no such guarantees, and if you have the dexterity to execute your strategy faster than your opponent can respond to, you should be rewarded for that.

>Imagine if you could express your ideas effectively into actual game actions?

Imagine the cost of such an interface in today's society, especially compared to a regular USB keyboard and mouse. Now imagine you're a game designer. Do you want to build a system that explicitly favors those rich enough to purchase the best equipment, or do you want to spread your playerbase as widely as possible?

Perhaps in another few decades, we can start rewarding the people with the "best" brains, but as long as we exist in meatspace, people are going to want to test their meat-skills against each other.

aetimmes··on The Importance of Deep Work and the 30-Hour Method for Learning a New Skill
I don't see anything that indicates agreement from the author of the post.
aetimmes··on Google Hangouts Chat
I'd argue that someone needs to needs to make a Google Chat Product equivalent of the Cleveland Browns Quarterback Graveyard jersey (https://pbs.twimg.com/media/Clb2inPWAAAh3lX.jpg), but Google seems intent on circumventing that possibility by using pants-on-head moronic namespacing.
aetimmes··on The Long, Slow Decline of BitTorrent (2017)
Valve have absolutely nailed the consumer-centric business model. Gabe Newell was the first person I heard the concept of "piracy is a service problem" from and they've turned it into their core competency.

However, centralization of the marketplace, even from a publisher standpoint, isn't a Good Thing. Steam's degree of control over the game publishing platform market is pretty pathological from the view of developers.

A better solution from the content creators' standpoint is a marketplace with competitors. In gaming, this doesn't really exist (maybe GoG/Humble?) but in streaming media delivery, it does (Netflix, Hulu, Amazon Video).

aetimmes··on “Let her speak please”
There's a distinction between scripted public speaking in a venue where all interaction is controlled and initiating real conflict in a public place with no such control.
