JustMatthew | 7 years ago | on: Bitcoin's Use in Commerce Keeps Falling
According to annualized energy forecasts extrapolated out from bitcoin PoW energy demands back in December 2017 (i.e. at the height of the recent crypto bubble frenzy) BTC miners are expected to use 8.27 terawatt-hours this year. That's more energy than 116 countries including the Democratic Republic of Congo.
On the other hand, the amount of energy bitcoin is forecast to consume in a year would only last the U.S. 19 hours. Additional the production of the global cash and coin supply will consume an estimated 11 terawatt-hours this year while gold mining will burn the equivalent of 132 terawatt-hours over the same period - and that doesn't include armored trucks, bank bank vaults, security systems etc...
I'm not saying it's worth it to burn all that energy to keep bitcoin (arguably) decentralized. I just want to provide some (now probably outdated) perspective to temper arguments, and stimulate others (on both sides) to advance their arguments beyond headline quotes.

JustMatthew | 7 years ago | on: Companies shouldn't give candidates homework assignments
Speaking from experience, shooting 1~2 very detailed hypothetical situations (i.e. 'homework') to a candidate 1 hour prior to their interview and asking them to think of responses to a few 'hard questions' that they will be asked to 1) answer and 2) explain their reasoning during the interview tends to work well. This usually reduces candidate anxiety, helps the evaluating committee get a better look at the candidate's approach to problem solving and validates (or not) their previous experiences, and improves the flow and time management of interview itself.

JustMatthew | 7 years ago | on: After 60 Years, I-95 Is Complete
If you say that you don't want to trust data compiled and reviewed by an association of civil engineers, then you should probably stop using ADA approved toothpaste and cease getting those AMA recommended medical check-ups.
I hope that didn't come across too harshly, but there seems to be a wave of anti-intellectualism that has been spreading across the US. Obviously that sentiment has formed in no small part due to actual abuses that have been carried out by those with vested interests, but we need to be careful that we don't take what would otherwise be a healthy skepticism of the actions and proscriptions of organizations too far and mis-trust all professional organizations or everything that they publish...
JustMatthew | 7 years ago | on: Ask HN: How did you find your current job?
This may seem like a lot (at least it kind of felt like a lot as I was writing it), but I am well rested, excercise every evening with my wife, read a lot, meet friends, blog daily, feel like I can do more and am just having a great time being alive.
JustMatthew | 7 years ago | on: Ask HN: How did you find your current job?
For my nights and weekends gig at Cent (https://beta.cent.co) I had to make it. I first focused on becoming a super-user back in October of 2017. After that, I submitted a few un-returned emails to the founders and wrote over 50 blog posts on the project before finally receiving a follow up email asking if I wanted to chat with the two person founding team. We had an amazing first call which led to a second one where I presented a plan of what I could do for the project in terms of their social media and communications strategies. After that the team asked for my ideal conditions before making an offer to join the team which I happily accepted.

JustMatthew | 7 years ago | on: Solitude appears to have an image problem in Japan
Beautiful post, and I think that line encapsulates quite perfectly what any thinking person should keep in mind when it comes to discussions on solitude and socialization.
The difficulty of achieving that balance is that it differs person to person, and culture tends to compound the difficulty of achieving the perfect individual balance.
Imo, self-knowledge and the self-confidence it helps canalize offer the only navigable route through the overpowering currents of culture towards that island of balance.

JustMatthew | 7 years ago | on: Are Facebook and YouTube quasi-governmental actors?
That's quite literally a small army (for reference, it appears the number of active duty US marines is around 200k).
Without commenting on the causes this (or any other) army of followers believes in, it's staggering to imagine what kind of impact monetary incentives, dispersed, for example, by way of an autonomous smart contract that is funded by anonymous donors via 'x' cryptocurrency that relies on some simple proof of action for payout, could have on the frequency and magnitude of actions such groups carry out.
We really are at the beginning of a new chapter in the history of humanity.

Each episode is accompanied by super detailed show-notes that summarize the episode nicely, so you can see if the episode has what you think you may be looking for.
Cheers and good luck.

I have my vision checked in the contact store itself (for free) if I need it and then a proper eye exam during my annual physical check up (which is fully subsidized by my employer - a common practice, albeit at varying levels of support).
JustMatthew | 7 years ago | on: I’m a very slow thinker (2016)
Everyone is different, and I am sure people will agree or disagree with the point the author makes to varying degrees depending on their own lived experiences and abilities, but after reading this I think it'd be difficult for anyone to not admit that there is most certainly value in taking an asynchronous approach to conversations and discussions.
And man, does this quote provides some hearty food for thought or what: "Your first reaction is usually outdated."

JustMatthew | 7 years ago | on: Decentralising the web: Why is it so hard to achieve?
The various communities on Steemit all seem to focus rather passionately on protecting their hashtags and feeds from users or content that are abusive or spammy.
JustMatthew | 7 years ago | on: Scorching Summer in Europe Signals Long-Term Climate Changes
For parts of the world like Europe where such extreme temperatures have been relatively rare, it will be extremely interesting - not to mention super unfortunate - to see how long it will take for individuals and societies to adjust to what very well may be a new normal and/or how it may impact migration (both in and out) patterns.
JustMatthew | 7 years ago | on: Ask HN: What are some niche communities you enjoy?
The sense of community is surprisingly strong at Cent, which is kind of amazing for a site where the stated purpose is to provide a way for anyone to earn income from anywhere by paying users for providing responses that are no different than FB posts or Tweets. The difference between Cent and FB and Twitter though is that users on Cent are responding to posts that have a monetary bounty attached to them, so users are incentivized to make quality responses in order to get a piece of the bounty. Users also get paid for making the equivalent of a FB like or Twitter heart (but don't quit your day job to like responses since we're you'll earn a few cents per bounty).
I'd say more, but heading over to https://beta.cent.co/ and trying it out for yourself is more effective than any explanation.

It's amazing how much of a time saver and efficiency builder that can be. It's equally amazing how many managers prefer time wasting group meetings where people essentially read written reports...
JustMatthew | 7 years ago | on: Show HN: BountyGraph: Crowdfunded Bug Bounties and Security Audits
That said, as a non-coder but an avid bounty setter and bounty hunter on beta.cent.co, I am wondering if there aren't any other UX tweaks that could be employed on BountyGraph to either attract and keep more bounty hunters or participating corporate users/funders or both.
Specifically, the social aspect that Cent facilitates has resulted in a very interesting general community that also functions as an army of on-demand bounty hunters. I imagine something similar but tailored to the technical bounty hunters your site will need could be spun up at a cost to be sure, but a relatively small one compared to the value that attracting such an army of bounty hunters could generate.
