I would ideally like to avoid having to learn to navigate the ins-and-outs of an overly involved compiling process, a complicated IDE, or loads of SDKs. I want to be able to get straight to the coding.
There are a couple of things that really interest me, so bonus points if material relates to one of these in some way: agent-based modelling, simple iterative evolutionary processes, and simple AI (e.g. non-instructed collision detection).

Consider an intelligent social species. When two strangers meet, the ability to judge accurately and to be favorably judged, both lead to better fitness. Lets assume there are situations where intelligence is the dominant quality that is being evaluated. Now if you are intelligent, you want to honestly communicate this, so its in your best interest to aid the judgement of the other person. If you are not, then its preferable to be dishonest and try and simulate intelligence. Now why should this situation lead to a state where (some) people can fairly easily make accurate judgements about others? It seems like the person judging has no easy way of accurately evaluating, but has to undertake the hard task of distinguishing between liars and truth-tellers. But the interesting part is that lying and intelligence are highly correlated, since lying takes more brainpower than just telling the truth. So the people who can fool the judgement of others, don't really need to, while those who need to lie, can't do so effectively.

I also think fitness is important and have been working out all of my adult life. Before Aviron, I worked full time and long hours so I did a lot of my thinking during late night gym sessions. Like many people I avoided the rower because not only did I not enjoy cardio but damn that machine was hard and boring. There was a moment at some point in 2016 when I realized I could do something with this. The connected fitness market in the US at that time was small but growing rapidly.
Aviron is a rowing machine because it\u2019s the most efficient and effective workout you can have in a short amount of time on one machine. The rowing motion is low impact, engages 85% of muscles, is very difficult and as a result can also be boring. This makes the rowing machine an ideal \u2018candidate\u2019 to pair with the gaming-inspired, competitive content I began thinking about in 2016.
The research was telling me there was a definite potential market niche I could fill but what I didn't know was that no manufacturer would speak to me. I probably called and emailed 50 manufacturers. I eventually kickstarted a few conversations and finally a relationship, by flying to Taiwan, connecting with a local who could translate, and knocking on doors in person. It sounds reasonable in hindsight but the process to finalizing a production contract start to finish took me a full year. A year of trying to understand the manufacturing landscape, developing relationships and convincing potential suppliers that I would eventually be worth their time.
Ultimately my key takeaway is that Taiwanese manufacturing relationships are just that - relationships. Manufacturers are looking for long-term trusting partnerships and they are much less motivated by money than my initial assumption. I\u2019m reminded of this constantly - this month alone I have received emails re: product delays twice - and I stupidly tried to throw money at the problem, in the process offending the Taiwan team by implying they would work harder if money was on the table.
Finding and building a solid relationship with a production partner was challenging but I would give it a 7/10 relative to the hurdles that came later. The manufacturer had no experience or interest in getting the machine to work along with our custom android touchscreen. As much as I see myself as a \u201ctech guy\u201d, I don\u2019t have an engineering degree. My dad does and so does my brother but I went the business degree route. Long story short, figuring out the details of making these two pieces work together was a nightmare. Again, in hindsight, it\u2019s kind of cool - I understand my machine inside and out; I\u2019m confident I could take it apart down to the screws and put it back together. I can also work comfortably with an oscilloscope and understand how most of the components work on a typical fitness equipment circuit board - there was a lot of circuit board soldering trial and error at one point.
I knew that I was taking on a lot with a software and hardware venture but what nobody tells you is how many miles you\u2019re going to drive and fly when you\u2019re taking on hardware. During our slow tip-toe pivot from B2B to B2C sales, we discovered home customers would find 10x the problems a gym would. There was a week in 2019 I drove to a customer\u2019s home 6 hours away multiple times a week for nearly a month. Each trip I thought we had found the solution; the ride back was crushing. This was one of many problems we faced.
I\u2019m happy to be able to say the bugs are mostly worked out! Our customers navigate a 22\u201d touchscreen to browse 250ish content options - like my favorite and the first game we ever developed - Last Hope, an end-of-the-world inspired game where you\u2019re being chased by zombies. As your row to escape the Ai will benchmark your fitness output and adjust the zombies\u2019 speed to maintain a challenging pace for your fitness level.
The content for Aviron was developed with strength training and High Intensity Interval Training (HIIT) in mind. For example, one of our 6 workouts categories is \u201cPros vs. Joes\u201d, a program that allows you to compete against pre-recorded Olympians and professional athletes in a race.
Our customers are fitness enthusiasts who don\u2019t enjoy long cardio workouts and crave the competitive and challenging pace of activities like CrossFit and F45, at home - especially throughout Covid. HIIT workouts tend to be shorter, have been proven to improve cognitive ability and help slow the aging process via preservation of DNA.
To me, the dual cognitive and physical benefits were really key. I began to work out in my teens, physically I felt better and my self esteem improved. Cognitively, I went from dealing with undiagnosed ADHD and struggling my way through school to slowly noticing an improvement. People told me I was \u201cgrowing out of\u201d ADHD - which is probably partially true - but something clicked when I was researching fitness programming for Aviron. Learning about HIIT and it\u2019s (data proven) benefits, I started to realize that my commitment to consistent and challenging physical fitness had likely paid a large part in my \u201cgrowing out it\u201d as well.
Currently, we have bootstrapped Aviron to a good place; we\u2019ve sold nearly a thousand rowers to gyms, hotels, schools and even Nike headquarters as well as homes. Or churn rate is <1% and our customers are telling us they\u2019re happy. And they\u2019re paying their membership every month so we believe them. :)
We are continually working on Aviron to improve the software, content and customer experience so if you have a chance please check us out and let me know what you think.

We build AI agents that discover new materials for the semiconductor industry.
GPUs today have a heat problem. Nvidia & AMD are almost doubling the TDP (Thermal Design Power) in every chip they release - the H100 (released 2022) has a TDP of 700W, Blackwell (2024) gives out 1.2 kW and Rubin (2026) gives out at 2.3 kW of heat. This trend is expected to continue, and getting rid of this heat is one of the major reasons datacenters consume so much power and water today - they need it to keep chips cool during operation.
The amount of heat produced by a chip and its ability to dissipate it are both influenced by the materials used to make it. For example, we could reduce the energy per bit required to move data between logic and memory by 10-50x by 3D packaging chips (placing HBM memory stacks directly on top of logic chips, instead of placing them beside logic on a 2D circuit board). However, we're unable to do this today because the dielectric material used in HBM (such as SiO2) is a very poor thermal conductor, trapping heat between logic and memory and causing drastic temperature rise during operation. Similarly, there's many other materials in the GPU that are being re-evaluated today - 2 more examples are thermal interface materials and substrates. However, getting a new material into a fab takes years and hundreds of millions of dollars of research - the infamous "lab-to-fab valley of death".
At Discovered Materials, we're optimistic that AI agents can reduce the timeline and cost required to introduce new materials into semiconductor chips. We're seeing glimpses of this already - we tested 7 models from Anthropic, OpenAI and Kimi, and found that they're all able to computationally discover new materials that are dynamically stable and possess promising properties. This was surprising to us - it would generally take a PhD student a couple of weeks of work to discover the kind of materials that these models find over an 8 hour run!
However, computational discovery is the easy part. A material discovery is only valid if the material can be made and tested in a lab (As an example, graphene\u2019s properties were predicted in 1947 but it was made for the first time in 2004). Today\u2019s models are not good at coming up with synthesis recipes to make materials in a lab. Even if they do get better at it, we're uncertain about how much that will help - making a new material is a highly empirical process involving trial and error over many experiments. Human experts themselves cannot "one-shot" the task, but we expect that a highly capable model will reduce the number of experimental iterations required to make a new material. We\u2019ve seen some evidence of this over the 3 months of our Y Combinator batch - we simulated, synthesized and tested thermal interface materials (TIMs) that match the performance of TIMs the world's largest chemical companies have guarded as trade secrets for over 20 years.
We\u2019re releasing hundreds of hundreds of new materials discovered by frontier AI models, as well as our benchmark which measures model ability on material discovery here (also linked in the thread url): https://discoveredmaterials.com/research. It covers what we discuss above, as well as a variety of strange behavior that we observe from the models, such as Claude's propensity to reward hack or GPT-5.6 occasionally losing its mind after ~50M tokens.
Our business model: We aim to license and sell IP on the materials we discover, as well as the IP on how to make these materials. We're also exploring an alternate business model where we sell the harness+tools we use to discover materials to semiconductor and chemical companies, allowing them to discover materials on their own. We're leaning towards the latter to start, but we expect that we'll do both in the long run.

X problem would keep me from getting accepted.\" If you don't mind, I'd like to explain one possible answer by telling you about my experience of applying to YCombinator.
I first wanted to apply to YCombinator's Summer 2007 cycle with the intention of making teachers' jobs a little easier. I was going to make an exceptional homework creation tool, one that would be intuitive to use. But wait, I could code it, but I didn't have any cofounders. Without a cofounder, I had no hope of getting in.
So I looked around for one. Everyone at work had families, so they were out. But I had a wonderful, supportive girlfriend. Why not her? What a strange idea, to start a company with your girlfriend! But I talked with her about it, and we started working together. Then something pretty amazing happened. It never mattered that she had zero technical knowledge. She knew what worked and what didn't, what made sense and what didn't. So we created something and ran it by my father. He said, \"This is a little hard for non-technical people to use. I'll work with you on it.\" Now all of a sudden, I had two cofounders.
In the meantime, I received an invitation to Startup School. Not only that, but I was invited to the dinner at YCombinator beforehand. Wow! That was a wonderful feeling to be invited to something like that. I was all smiles the rest of the week. I was going to California!
.. And it was approaching fast. I asked off work for that Friday and Monday, then everyone pulled a few crazy all-nighters to get the demo done and our YC application in top shape. I'll always remember everyone doing a ten-second countdown right before we hit the 'Submit' button. That was hands-down the most fun I've had in one night.
Since we worked so well together, and since we had a deadline to meet, we'd ended up with an excellent demo. And had a lot of fun all around.
So I was off to California. Weebly happened to fit in nicely with what we were doing (teachers could use Weebly to build their sites), so I met with Chris, Dan, and David. They're really fun to talk with! They had framed a little circuit and hung it on the wall that displayed a count of how many users they had. The geekiness of that had me chuckling. And the view from the YScraper was absolutely spectacular.
Up next was the YCombinator dinner. It was amazing to see Dexter in person. I couldn't get over that I was staring at an actual life-sized robot that was balancing on its own. I noticed a claw on another robot, so I asked Trevor to squeeze my hand with it. Yeowch! But now I'm a part of a small group that can say they've been attacked by a robot.
I met the Zenter guys, Wayne and Robby. I showed our demo and they thought it was excellent, which is really awesome to hear from rockstar coders like them. Then I saw Zenter and was put to shame :) It was great to see all the amazing stuff they did. After talking for a little bit, I was amazed to learn that Wayne had a kid on the way. Wowza, that's pretty brave to still do YCombinator! But we all know how Zenter worked out.
The night wore on, and at one point Paul seemed to look at me and do a high-five gesture, so I high-fived back. Then I looked behind me. Whoops, he was going to high-five someone else. Everyone laughed. He asked me what I did, and I replied without thinking, \"I'm making teachers' lives a little easier. I'm making a homework creation tool that even teachers will know how to use.\" \"Don't use that as your tagline, or you'll alienate all your customers,\" he said and grinned. D'oh, I didn't mean it like that, but everyone laughed again. Looking back on it, that whole encounter was pretty amusing.
Up next was Startup School, which was a blast. Afterwards, I had some time to kill before catching my jet home, so I hitched Caltrain into San Francisco and waited in line to catch a taxi. I talked with the guy in front of me for awhile. He was from the midwest and came to San Francisco on a business trip. He was interesting to get to know, but then a taxi pulled up. To my surprise, he offered me his place. \"Thanks!\" I said, and hopped in. \"Do you know any great places to get Sushi?\" I asked the taxi driver. He nodded, and we were off. \"Hey,\" he said, \"That guy gave you his seat. Why'd he do that?\" \"I dunno, I guess you just need to be nice to people and they'll do stuff like that.\" \"You Christian?\" he asked. \"No sir, just on vacation.\"
The sushi was amazing, but the oysters were pretty terrible. I caught a taxi back to Caltrain, and the taxi driver was as bad as I was with directions. She and I got lost about three times, and we laughed about it. She was probably taking me for a few extra bucks, but I prefer to think she was just new on the job. Anyway, she was nice enough that I didn't care.
I flew back home, and everyone anxiously awaited YCombinator's response. All of a sudden, it showed up. No dice. Oh well.
It must've been quite an amusing application. Some nineteen year old and his eighteen year old girlfriend with his fifty year old father. And I let the rejection get to me for a day or two, but then I felt stupid. If I didn't apply, I would've missed out on one of the best experiences of my life. I wouldn't have applied to Startup School, or talked with the Weeblies or the Zenters, or made a fool of myself in front of Paul, or been clawed by a giant robot, or stayed up late with everyone working on a Really Cool Idea, or done a loud ten-second countdown before hitting the Submit button, or eaten San Francisco Sushi, or astounded a taxi driver when some random stranger gave me his seat, or felt really good about working as hard as I could on something to show someone else, or a hundred other little things. And all those, I think, are reasons to apply to YCombinator. So go ahead, don't apply... But you might be missing out on a whole lotta fun.
But if you don't care about the fun, there are plenty of other reasons. Since you have a deadline, you'll get more done than you ever thought possible.

X problem would keep me from getting accepted.\" If you don't mind, I'd like to explain one possible answer by telling you about my experience of applying to YCombinator.
I first wanted to apply to YCombinator's Summer 2007 cycle with the intention of making teachers' jobs a little easier. I was going to make an exceptional homework creation tool, one that would be intuitive to use. But wait, I could code it, but I didn't have any cofounders. Without a cofounder, I had no hope of getting in.
So I looked around for one. Everyone at work had families, so they were out. But I had a wonderful, supportive girlfriend. Why not her? What a strange idea, to start a company with your girlfriend! But I talked with her about it, and we started working together. Then something pretty amazing happened. It never mattered that she had zero technical knowledge. She knew what worked and what didn't, what made sense and what didn't. So we created something and ran it by my father. He said, \"This is a little hard for non-technical people to use. I'll work with you on it.\" Now all of a sudden, I had two cofounders.
In the meantime, I received an invitation to Startup School. Not only that, but I was invited to the dinner at YCombinator beforehand. Wow! That was a wonderful feeling to be invited to something like that. I was all smiles the rest of the week. I was going to California!
.. And it was approaching fast. I asked off work for that Friday and Monday, then everyone pulled a few crazy all-nighters to get the demo done and our YC application in top shape. I'll always remember everyone doing a ten-second countdown right before we hit the 'Submit' button. That was hands-down the most fun I've had in one night.
Since we worked so well together, and since we had a deadline to meet, we'd ended up with an excellent demo. And had a lot of fun all around.
So I was off to California. Weebly happened to fit in nicely with what we were doing (teachers could use Weebly to build their sites), so I met with Chris, Dan, and David. They're really fun to talk with! They had framed a little circuit and hung it on the wall that displayed a count of how many users they had. The geekiness of that had me chuckling. And the view from the YScraper was absolutely spectacular.
Up next was the YCombinator dinner. It was amazing to see Dexter in person. I couldn't get over that I was staring at an actual life-sized robot that was balancing on its own. I noticed a claw on another robot, so I asked Trevor to squeeze my hand with it. Yeowch! But now I'm a part of a small group that can say they've been attacked by a robot.
I met the Zenter guys, Wayne and Robby. I showed our demo and they thought it was excellent, which is really awesome to hear from rockstar coders like them. Then I saw Zenter and was put to shame :) It was great to see all the amazing stuff they did. After talking for a little bit, I was amazed to learn that Wayne had a kid on the way. Wowza, that's pretty brave to still do YCombinator! But we all know how Zenter worked out.

Not like is this what I am doing for the rest of my life, but the more general question of is this what people work towards all their life. Now I am being a bit vague here, but hear me out and let me explain. It helps to have some background on my story so hold on...
I grew up by the city in the suburbs where you had your typical gang per neighborhood and cops cruising around the area at all times. Drug deals were a regular thing during class time and it was likely that if you followed in your parents footsteps you would be pregnant at 17 and potentially graduating high school with a drug problem. Most of my friends fell victim to drugs in one form or another, so I learned to steer clear of most of that stuff. Plus my dad told me he would kill me if he ever found out (little did I know he had his own problem with it all).
My parents split apart, but before my dad rolled out he set a solid work ethic in me. That or I realized home wasn't the greatest place to be around and decided it would be best to make money while disconnecting from my \"family\". I started work at 14 changing oil and found the ability to make my own money was the most liberating experience ever. I made a point to ditch the required high school work forms and limits and cut a deal with my boss, 30+ hours and I would make it work. During the summer I put in well into 50 hours as much as I could and enjoyed life.
Fast-forward a couple years and I am in high school goofing around in a networking class. I was told before joining the class that graduating from this school would land me 16 college credits and 19 if I passed the certification. Call it what you will, but I found high school to be a joke, so I went to college at night starting in 11th grade and decided I would make the whole school thing go by as quickly as possible. During this time I continued to work full time, and volunteered at some tech startup doing Internet sales. I also did the usual teenager activities like going to parties, hacking companies in the city, doing graffiti and running from the cops.
Jump ahead 1 year after high school and I am working for a government contractor building circuit boards on million dollar contracts. I graduated high school early, bent the rules as much as possible and was the proud owner of an A.A.S degree in network technology. I later moved on to doing network engineering, but remained with the company for a year before making my next big leap. Meanwhile at home I was planning on moving out because the situation was only getting more annoying.
I realized that finishing my degree was critical to making any money, so I made that my top goal, but knew I would be bored doing nothing but school. You have to understand that at this point I had pushed myself far beyond my normal means and what once was difficult was now the \"norm\". Sleep wasn't required and all I wanted to do was work. I decided to go to a local college that took in all my transfer credits where a lot of the courses were online. I managed to re-write parts of my degree and pull 18 credit semesters while working the 50 hours as a security engineer while still having some sort of life.
I graduated early with my B.S in Information Assurance and managed to get a couple speaking engagements in the middle of that. I spoke at one of the biggest hacker conferences in Vegas, on career panels with college professors and offered my advice to those who asked or listened. Fast-forward some more and I have written articles for magazines, been offered crazy jobs with crazy money and have vacationed in some pretty cool spots. I have since fixed some of the issues with my family and feel as if I am becoming a more understanding person in regards to substance abuse and mental illness (things I have dealt with a lot).
Life and work are great and just in this year I have been to Canada, the Bahamas, Europe, California and Vegas. A lot of these were for speaking, some for vacation, but all of them great trips. When I got back I would tell my family how things went or what was on my mind. In some cases I wasn't too excited over everything and the comments my family made were more or less that they wish they had my life. It wasn't that I wasn't happy with all of this stuff, but it made me wonder if this is what people worked for. Was what I had someone else's dream?
I work at a university now doing forensic investigations and malware analysis. I could be making a hell of a lot more money else where, but I enjoy the people I work with and what I do everyday. I often stay late and base a lot of my life around doing things in the general area. Because I am staff, I get tuition benefits and while I thought I would never go back to school, I am thinking now it may be worthwhile since it's free. I am not sure if I want to focus on technology or if pursuing a degree in something else would be more of my thing. Either way, I think it would be nice to experience a little bit of the college scene I missed out on by rushing before.
Outside of work I race road bikes, workout a lot, am not too social, but keep enough friends around not to be terribly bored or alone. I go on several trips throughout the year and keep life interesting through funny experiences and the general mentality that life is about stories, not salaries. I know it is who I am to continue working like I do and to do everything I try to the fullest. I am excessive, easily bored and always seeking some challenge. I am far from being old or done, but there are times when I wonder if I will burn out. Will I work too much? Should I be doing more? Should I be doing things differently?
I guess the last thing I would point out is that I recognize I don't know everything and that I haven't tried everything. There is still a lot more I could be doing and a lot I could change both around me and within me. The \"being a better person\" aspect seems to take longer than changing what I'm surrounded by, so I hope this doesn't come off like a poor me, help me out sort of posting. It should be instead interpreted as someone who has done a decent job for being 23 and wants help knowing how to make life even more awesome.

We had taken a digital logic course, but were disappointed with the fact that the most complex project we did was building a full adder in Quartus using logic blocks, not even in RTL!5 Therefore, we decided to challenge ourselves to dive deep into machine learning (ML) hardware and learn as much as we could on our own. We wanted to prove that basic math (like y = mx + b) and basic logic circuits are enough to help anyone understand how modern AI hardware works.
Our goal was to design our own version of the LPU from scratch and run a simple Transformer-style model on it, proving that with minimal Machine Learning and computer design knowledge, it\u2019s totally possible.

- I also can't use my old Macbook Pro well, because the replacement Transcend 256GB SSD I put in it around 2020 is now failing, causing the machine to unpredictably become very slow. Also, the HP business keyboard I bought some years ago is suddenly now emitting spurious key signals, which MacOS (curse its over-reliance on weird key combinations and gestures) is interpreting to do wild things, like repeatedly showing the desktop while I'm working, or zooming in and out repeatedly.
- I thought I could use my old iPad in the meantime, but it can't connect to the WiFi hotspot on my iPhone, only a normal WiFi. I thought WiFi was just WiFi?
- The Dell travel hub I bought a few years ago seems to not work on a whim when I try to use it to make an HDMI connection between my Macbook and my Samsung monitor. About 50% of the time, it simply does not work, no matter what I do. I tried using my Roku ox to cast my screen, but the Roku remote suddenly does not work. I also tried my old Apple TV; its remote was also not working properly. After somehow getting to work to connect to WiFi, the Apple TV also does not work, giving some cryptic error messages.
- A few days ago, my iPhone 12 mini simply refused to charge from my USB-C to lightning cable, no matter what I did, for hours. I borrowed a similar cable from a friend, it also did not work. So my phone died when I needed it. When I got home, I was able to charge with a USB-A to lightning cable.
- Whenever I plug in the external Crucial SSD I bought a few years ago and partitioned, it does not show up in Finder on macOS. I almost always have to go in the Disk Utility to mount the partitions.
- My Sony Bravia TV died suddenly after like 7 years. I took it to some repairers; they said the entire screen is kaput.

As a client (renting GPUs) I've found it to be pretty unreliable. I've tried renting GPUs a handful of times and hosts, bandwidth, and performance are all over the place compared to what's listed in the console. I suspect people are gaming the host benchmarks somehow. Additionally, even when using on-demand instances the reliability is nowhere near what's reflected by the reliability/uptime metrics reported in the console.
While they've done a pretty good job considering with their software stack it's still kind of a pain to use with significant limitations and multiple hoops to jump through compared to say a GCP/AWS GPU instance.
That said, there are stories of people using vast.ai successfully so maybe I've just had incredibly bad luck?
From a hosting standpoint I can't figure out the economics/opportunity:
Median pricing in the US for a verified RTX 3090 is $0.38/hr. Let's assume total capex is $2000 (likely much higher looking at reported hardware configs).
Assuming US national average electricity costs of $0.15/kWh and hardware being under fairly high utilization you're probably looking at 500 watt load. Let's assume costs like bandwidth, etc are baked in because it's hosted on a circuit you'd be paying for anyway.
So ongoing operational cost (power) is $0.07 (rounding down). Vast.ai takes 25% of listed pricing. Basic math for this theoretical host:
Rental fee (median): $0.38/hr
Less vast.ai take: $0.29/hr
Less power cost: $0.22/hr
Less taxes (they ask for SSN/EIN so I assume income reporting) at effective (low) tax rate of 10%: $0.20/hr
Absolute best case monthly income assuming full usage with 730 hours/mo: $146
Yearly income: $1752
ROI for hardware capex: 14 months
The numbers for A100 PCIe rental are much worse - median rental cost of $0.79/hr with a $15k card. You're never making money on that...
I assume most of the hosts are fairly technical and their time is relatively valuable (imagine a random tech consultant that makes $75/hr). If you consider this side gig "work" and spend an hour a month dealing it (even controlled maintenance, etc) your monthly income drops in half relative to your ability for billable time (opportunity cost).
In the case of sharing an internet connection for a remote worker/home host without fairly advanced QoS bandwidth bursts could absolutely wreck the usability of your internet connection. Your fans will be screaming anytime you're actually "making" money, dumping hot air in your environment, potentially increasing air conditioning power costs, etc.
PLUS now you have random internet users on your internet connection (and potentially LAN!) which opens up all kinds of security/legal issues.
How can this possibly be worth it?
Is this just desperation because of the collapse in cryptocurrency mining? What about the A100s, etc listed that no one in their right mind would have bought for cryptocurrency mining?

I was hanging out in an IRC channel for a local Linux user group, and lo and behold, there was a guy who worked in a local datacenter/hosting company. I got the manager contact from him, and basically called and emailed and bothered the hell out of him until he relented and said OK come work as an unpaid intern. I worked hard, learned and incredible amount there (they hired me on after a few weeks, albeit very cheaply of course)\u2014 DNS/network/webserver/troubleshooting, all the fundamentals, and there were incredibly smart and brilliant people there that I learned from. Those were very cool days. From there I excelled and have done fairly decently for myself. Good amount of luck on the way probably, sort of right situation/right timing... have worked at two very large ISPs/telecoms in Systems and Server Operations since then. Wanted to share this maybe to also give encouragement to people just to keep trying and working hard and it can work out. Potentially also a good message in this hard time of the Coronavirus. Would love to hear some other foot-in-the-door stories.","title":"Ask HN: What was your foot in the door?","updated_at":"2024-09-20T06:12:25Z"},{"_highlightResult":{"author":{"matchLevel":"none","matchedWords":[],"value":"benjamind"},"story_text":{"matchLevel":"none","matchedWords":[],"value":"Hi all,
I've been lurking here for a while, not really got involved yet, but recently took the plunge to turn to self employment and startup life.
I quit my job and moved to a lower rent area so my savings would last a little longer, and decided to turn my long time hobby project into a full-time startup with the help of a friend. Now a little over two months in, the demons are starting to gather and I'm beginning to question my decisions.
The project is an in-browser Canvas based circuit design tool. Allowing users to create electronic circuit schematics and embed them on their blogs/forums/websites. The key feature being that the schematics are 'live' so can be zoomed in/out and are a lot more interactive than a static screenshot.
I came to want to solve this problem after running into it myself last year while trying to design an electronics project with a friend. It was really hard to collaborate and it was equally hard to get people to help out when we had problems, purely because it was hard to share the circuit design with them in a readable form.
We have come quite a long way with this project, its probably a couple of months away from having a minimum viable feature set. (Still lots to do after that of course). It is right now far from polished, and has many rough edges, and is mostly full of test data. But we feel a need to get it out to some eyeballs other than just ours.
So my question is when should you start showing potential evangelists and advisers your application?
I have some people in mind, people who have fairly high profile within the hobbyist communities, and people who have experience with electronics circuit design tools. I have contacted some of them already to see if they would be interested in trying out an alpha release and have had very positive feedback. I'm just afraid to show them the application too early, when its still very much unfinished.
I know the general rule of thumb is to get feedback early and often, but when an application is not even at an MVP stage, does this still apply?"},"title":{"matchLevel":"none","matchedWords":[],"value":"Ask HN: When do you show your project to potential evangelists and advisers?"},"url":{"matchLevel":"none","matchedWords":[],"value":""}},"_tags":["story","author_benjamind","story_2197159","ask_hn"],"author":"benjamind","created_at":"2011-02-09T11:54:20Z","created_at_i":1297252460,"num_comments":0,"objectID":"2197159","points":2,"story_id":2197159,"story_text":"Hi all,

Some time ago I decided that programming is something I enjoy doing. A few years and night school calculus courses later I got into a university computer science program on the second year of which I am now.
I found the software engineering and general computer science courses rather easy, including those that taught Python, Java and the intro C/UNIX course.

A few of my friends have zero problems with the more rigorous courses, but are completely useless when it comes to even the most basic object-oriented design and even version control, which took a surprising amount of effort to explain.
When I first came to see the university counsellor, we parted ways with him saying \"we will turn you from a coder into a computer scientist\", which is precisely what I'd like to take away from post-secondary education.

The secret to infomercial's success in motivating people to incur great costs (time or money) is about emphasizing the rewards. 90% of the stock market infomercial is about the great wealth that can be accumulated by buying their service. They are able to switch on the reward circuits associated with a given task. This is the same feeling we get when dreaming of a juicy bacon cheeseburger. We can feel or even taste the rewards we can reap with every bite of that burger. This is why we can barely control ourselves from eating it.
