lfuller··on Air Fares 101 – Why do fares change all the time?
I know Air Canada does this pretty blatantly. When searching for flights they constantly go up by $50 - $100 an hour then magically reset to the original price when I open up an incognito browser window.
lfuller··on Freelancing: How to talk yourself into charging more
This sounds comparable to the dog-walking lady in the article. If I were you, I'd have walked away from that one. It sounds like the team lead wasn't interested in the value you'd provide, she just wanted a cheap developer.
lfuller··on Orion Flight Test Live Launch
Not true in my experience. I've lived in five different provinces and I've never met a Canadian who uses Farenheit. I've never met anyone under 40 who knows much more than >100F = hot either.
lfuller··on Orion flight test rescheduled for tomorrow
It's liquid oxygen venting.

Oxygen can be kept in a liquid state by either keeping the temperature extremely low or keeping it under high pressure. Since reinforcing the tanks to handle incredibly high pressures would require too much weight, the tanks are instead constantly being topped up with cryogenic fuel until the moment of launch.

As for the venting: the fuel starts heating up and evaporating as soon as it's pumped into the tanks causing the pressure within the tanks to rise. Since the tanks aren't rated for high pressure, they have to vent the excess oxygen to keep within safety margins.

lfuller··on Show HN: Quiver – The Programmer's Notebook
How is this different from Evernote? I use Evernote for this exact purpose using their notebooks and tags. The UI looks to be based on it as well.
lfuller··on Is the NYPD About to Start Ticketing More Cyclists Due to a Mathematical Error?
That's not relevant to the discussion. This article was disputing a claim that "the 5th Pct. had a 115% increase in bicycle collisions this year", not that NYC in general had an increase.
lfuller··on Is Faster-Than-Light Travel or Communication Possible? (1997)
That's not true. From the perspective of the travelers space will appear to contract dramatically - though the speed of light remains constant, the distance traveled is reduced.
lfuller··on Why Loggly Chose AWS Route 53 Over Elastic Load Balancing
I was thinking the exact same thing while reading this - it reads like a company that doesn't understand the unique challenges involved with distributed computing.

I'm actually in the middle of deciding between Loggly, Papertrail, and Logentries for centralized log management. I guess that cuts it down to two.

lfuller··on Sentimental versioning
The page was satirical. Given the content, the author is likely pro semantic versioning.
lfuller··on Brain changes are associated with casual marijuana use in young adults
In my opinion, possession should be legalized in every case; it's not the government's business what I choose to put into my own body. In the case of dangerous drugs and medications it should be distribution / intent to distribute that's regulated.
lfuller··on Ask HN: What are some Bay Area startups that don't use an open office plan?
A bit off topic, but does anyone here prefer / not mind open office plans?

As someone who prefers open office plans to private offices / cubicles, I've always wondered if the large number of anti-open-plan articles are because that opinion is the majority, or because it is the loud minority.

lfuller··on Marijuana Law Mayhem Splits U.S. In Two as Travelers Get Busted
I'll never understand the logic behind this. How come cancer patients or people recovering from surgery with powerful opiates aren't thrown in prison? Why is possessing a chemical used medically a crime? (This is mostly rhetorical, but still sad.)
lfuller··on Elon Musk’s SpaceX Is Raising Money at a Valuation Approaching $10B
If the ticket is only $500k, I don't see it being limited to the top 1% richest. Given that you're making a one way trip to another planet, you no longer have need for any of your property including your car and home. If a middle class person making $80k - $150k were to save for 10 - 15 years then sell all their property then they certainly would be able to put together $500k. I know I'd be willing to go if Musk is able to pull this off.

In terms of compensation for the colonists, what are you going to do with money when you're on a dead rock 225 million kilometres from Earth?

lfuller··on In-Line Images in Messages – Facebook Patent Application
I found it apt given the type of patent.
lfuller··on Is Every Speed Limit Too Low?
I believe it's implied that the limit itself is unfair.
lfuller··on Two nuclear bombs nearly detonated in North Carolina in 1961
The nagasaki bomb was actually only 2% of a megaton (21kt).
lfuller··on Rustle, Tingle, Relax: The Compelling World of A.S.M.R
Is this phenomenon the same as the "goosebumps" you often get when listening to a favourite song or thinking about a happy memory?
lfuller··on Emacs and Vim
I do! I have both tmux and vim configured so that <C-{h,j,k,l}> will navigate through both kinds of splits.
lfuller··on The New York Times Calls for Marijuana Legalization
A smell that you don't like isn't comparable to destruction of your property or having toxic waste thrown on you.

I have a neighbour that often cooks curry; I can't stand the smell of curry. Even though the smell comes in through my windows, I don't have the right to force them to stop cooking. I just close my windows.

lfuller··on Coinbase Vault
I'm confused as to how this is Coinbase's fault.

The entire point of two factor authentication is that it's impossible for someone to access your account without knowing your password and having access to your code generator. You chose to lose your code generator by getting a new phone without backing it up, AND you removed the phone backup that was provided for you.

This is like getting a new keychain, throwing out your old keys, then getting angry at your bank because you can't get into your safe deposit box.

lfuller··on Emacs and Vim
I don't understand why people want to do this in Vim. To me, a text editor should be extremely good at text editing / analysis and nothing else.

I use tmux, so all the advanced functionality of the terminal is only a single keypress away (to switch to another open terminal split).

lfuller··on Macroscopic quantum objects cannot exist if P ≠ NP?
By this logic, shouldn't the existence of the universe be impossible since simulating it mathematically in its entirety is infeasible?
lfuller··on Paletton – Color Scheme Designer
Spyware, not malware. Unless they are somehow attempting to take over control of your computer or perform some other crime.
lfuller··on Programmer excuses
This is why Vagrant / Chef is so great.
lfuller··on Six Months After Legalizing Marijuana, Two Big Things Have Happened in Colorado
Yes, that would be just 20mg per can... I know that Red Bull is around 80mg per can and other energy drinks can be 275mg or more.
lfuller··on My Treadwater Desk
It's near Toronto, so it depends. -25C in the winter, 35C in the summer. Around 30C right now.
lfuller··on My Treadwater Desk
I actually start every day with an ice cold shower and find that it helps to wake me up and put me in the right frame of mind for the day. I don't claim it's anything more than psychological, but it's been a big help for me.
lfuller··on Microsoft takes down No-IP.com domains
My home VPN is unable to connect right now. I use a noip.me domain. The actions of both the courts and Microsoft are extremely concerning to me.
lfuller··on Fluid Tests Hint at Concrete Quantum Reality
The D-Wave devices that you are referencing are actually quantum annealing machines, not universal quantum computers. A quantum annealing machine is to a universal quantum computer what a mechanical computer is to a digital processor.
lfuller··on Sleep as a Competitive Advantage
This is all dependent on your level of exercise and rate of perspiration. A 72kg person would have to drink around 6.5L of water for it to become dangerous[1].
