I've applied 20 minutes before deadline, if I remember correctly. I guess the quality of the application reflects this fact :-)
I'm 46, single founder, scratching my own itch, so the expectations were low, in fact I even forgot about 28th until the day before yesterday.
More importantly, this rejection is a dead end. You've got rejected now what? What rational outcome you can extract from this simple fact? I think none, there's no feedback. It just says that somehow you do not fit YC profile.
Rejection from the potential customer is infinitely more valuable, because even if they don't give you any feedback (though they usually do) it means that your mental picture of your market is slightly wrong. Every piece of feedback moves the needle. Rejection from YC doesn't move anything anywhere. Or does it? (may be I'm just over rationalizing, I have such bad habit).
For example a strangely large portion of my early kicking-tires-users are either from government or some security/military/intelligence related fields. Like some company that says "if you're not from the law enforcement - move on, nothing for you here" on the front page of their website (they're doing some telecom stuff).
Why? I'm doing some stupid boring datacenter inventory management! No idea whatsoever. But for me it's a question of the universe and everything.
So, folks, move on and get some customers.
(yeah, go ahead, I'm just finishing one more feature, will follow shortly.... :-)
I think it's a pretty interesting product, it also looks pretty polished, and I guess it could find some traction among large companies, government, etc. :) , I guess they're looking at it because they're the ones that need inventory and documentation the most - I work for an insurance company, and I'm going to send the link to the people that manage the datacenter - they strongly dislike anything SaaS through, they might eventually consider it as a standalone or self-hosted product, but forget about it, SaaS is a much better business model :) .
But I don't think it's what Y Combinator looks for - it's not something that will scale to Unicorn-size, it looks more like a good candidate for a bootstrapped startup.
Edit: some nitpicks, "There is no obligations!" on the pricing page doesn't sound right. I do like the "Take no hostages" pledge :) but if it looks like customers might be bigger businesses, you could re-write it to be more serious-sounding.
Edit2: from the guy that manages our datacenter: "It looks nice, we'll take a look".
I worked remotely for 20 years, as developer, team lead and manager.
The number one advice - communicate. It's better to overcommunicate than undercommunicate. A mediocre developer beats a genius if the mediocre one communicates and genius gets his task and goes under water for weeks and then suddenly delivers the masterpiece. I've seen so many such masterpieces not needed anymore after weeks of silence.
If you ever question yourself: "should I comment on this JIRA ticket before I complete it, or not?", don't hesitate, comment. Don't even think about it. If miracle will happen and you'll actually overcommunicate - they will tell you.
Number two: if you have a family, establish a comfortable working environment, define comfortable working hours and "go to the office". You're away, you can't "hey, could you please pick up some groceries, if you're at home anyway?". You're not at home, you're at work. It's hard for family, could be hard for you too. Especially if you have small children, your wife is very tired dealing with them, it would be very tempting for her to go out with girls while you babysit. The next thing which will happen is your production goes down, you're called to the meeting with all the brass, your ass is on fire, because it seems your commit caused the outage, you spend 3 hours on webex and phone and computer, your baby shits her pants couple of times, paints the whole room with shit, and then sits in the middle of this horrible mess crying because you forgot to feed her on schedule. And you do not hear her, because you're in the headphones where 20 people talk at once. (true story, btw).
On working from home, a physical barrier for 'work' and 'home' may help. For example, a physically separate attic or basement space with door that does feel separate, and can be reassuring for a child, as it is seen as 'mommy/daddy work time/space' rather than feeling neglected (assuming someone else is at home to look after the child).
Yes, they usually leave the office then and/or take time off (for babysit). That's what I suggest - develop a mental discipline to "enter the office" and "leave the office". It's just the commute that gets shorter (instead of 30min in the car it's 30ft from the bed to the table) and you can ignore the dress code even more :-)
It depends on your IT architecture and more importantly on your software architecture. I did this IRL and I did it both ways and I'm doing it again.
If you want some ideas or guidance or want to ask specific questions - feel free. My email is in my profile, "about" section.
To be fair, (I think) you don't need to know category theory to successfully apply FP principles and/or use any functional language. I had a great (GREAT) success at using erlang not only not knowing what monad is, but even not knowing about existence of category theory at all, leave aside monads, monoids, functors, etc.
You also don't need to know category theory to understand what monad is 
This video is all you, as a practicing programmer, need to know about monads and it's just 1 hour long.
AutoCAD brought Lisp mainstream for mechanical engineers, architects, and so many other 'rocket scientists' that I believe Emacs pales in comparison.
I was programming AutoLisp (automatic correction of trace and drill patterns for PCBs) on the machine which wasn't even able to build a decent Emacs in reasonable amount of time (PC AT/286 12Mhz with 2MB memory :-)). I was able to build myself an Emacs only after I got upgraded to 386SX 16Mhz with the whopping 4MB of RAM.
Oh, I thought I'd never encounter this on HN. But since I did, here's the story:
Somewhere in late 80s my mother started to have pain in the abdomen. She went here, then there, then she finally did something like CAT scan or whatever, I don't remember, I just remember is was difficult to get this scan because there was just so few such devices in my home country (friendly advice for those who dream about state-provided health service: you don't take into account that you literally can die while sitting in line for months)
Well, it appears that she got gallstones and quite sizeable ones. Traditional conservative medicine (pills) didn't help much and she was recommended to take the surgical route. She declined because someone told her about urinotherapy. And she did that shit (well, piss) for the next 10+ years. The pains never completely went away, so she used some over the counter painkillers and was getting by so-so. Then one day she felt acute pain again, she was diagnosed with Stage IV pancreatic cancer, and died in agony in 6 months. She was always dreamed about having grandchildren and my wife gave birth to our daughter the same day my mother went to (totally useless and just an act of despair) surgery to remove the metastasis. Which failed (well, stage 4 and pancreatic - it sounds worse than death penalty conviction). She lived just enough to see my daughter once when she was 3 months old or something. The hospital literally threw her away to die at home (remember, my friends, you want state-controlled health service. The hospital was free. Free comes at a price) and I drove my wife and child to her. She died a few weeks later. In pain and agony.
(did I tell you about the state-controlled health service? I don't remember, but just in case if I didn't - strong painkillers are controlled like weapon grade plutonium. So the doctor decides how many pills you deserve and even if the doctor is good person, the state mandates the limit. And it's a serious felony for a doctor to break this mandate. Painkillers are not technically free, but cost peanuts. You can buy them on the black market though and get 8 years if caught)
An autopsy showed that her gallbladder was full with stones. Doctors said that with a VERY high probability this is a sole cause of cancer. If she haven't listened to the idiot who advised her to take urine instead of the knife or ultrasonic she probably have survived until now (her birthday was 10 days ago and she would have been 75) and was able to see her granddaugther grow in front of her. She died at 61.
You can probably figure out from this rant what do I think about you and your religion. Drink this stuff alone.
I'd probably be downvoted to hell for this, but fuck it.
I have no idea what the original post said, because it appears to have been too godawful to even stay in the thread, but I saw nothing in kika's that sounded like racism. Just seems like the commenter is opposed to whatever groups are pushing the treatment he says killed his mom -- hard to fault somebody for that.
Soviet Union. The country which basically invented and implemented state-owned free healthcare on a very large scale (the USSR population was on par with the USA population).
And, frankly, I believe USSR succeeded in this implementation. I mean you can't make it substantially better than it was (taking technology advancements into account). It was great at preventing epidemic outbreaks, vaccinations, general population health, etc.
My sister picked up typhosus in a very remote part of the country, disease not known to primary care physicians for decades (well, they study it in medical schools but just like a historical artifact). But the system worked perfectly, she was diagnosed, sent to a special facility, got necessary treatment (and became a subject of research with daily visits of medical students from all across the city) and got out perfectly well (besides losing all her hair, but that part recovered quickly).
It's just everything has its pros and cons. And when you preach socialized state-owned healthcare, don't think you'll always be at the 'pros' side. Some people end up at the 'cons'. I'm not saying that my mother fell victim to this system, she fell victim to the idiocy. But the system made her suffer beyond what is acceptable in the civilized world.
Cancer is basically a problem of the immune system. We have a lot of cancer cells in our bodies and our bodies manage to kill them quite efficiently. Something went wrong in your body and a cell or two survived.
I'm in no way a doctor (I have experience with cancer, but as a, hm, 'user', or better, observer) but IMHO the thrill of working in the startup and doing stuff that you really like can substantially help your immune system to fight the hostile lifeform in your body. "Positive" hormones stimulate the immune system.
On the other side, having not enough sleep, eating shit, having a lot of excess weight (having a little is considered good) would actually harm your immune system.
That said, if I were you, I'd take the startup job, but would take extra care of myself, not working 6x16+1x10 hours, eating right (not necessarily fancy or organic, just basically good food), exercising enough and having enough fresh air and rest.
One doctor once said to me that I can cure any illness by just sleeping 10+ hours a day. He was joking, but every good joke is just partially a joke.
Yeah, and buy COBRA. Just in case. Most likely you will just waste a couple grand on it, but this is your life on the line. Small companies use complete idiots as insurance brokers (large ones do too, but they learned how to hide this) these idiots may screw up you forms/submissions/cards/accounts/whatever even multiple times in a row. You'd better be covered while you sort this out.
