Fogleman has some really cool side projects in a variety of areas written in a variety of languages... and I noticed he’s got two kids! As a new father, how is this possible? Really boring/easy day job?

Having a daughter is an amazing experience that is rewarding in its own right but something that really scares me about fatherhood is not being able to do any deep work for the rest of my life.

Doing deep work is another part of living I really enjoy and I’m somewhat petrified that I’ll never experience it again. Maybe it doesn’t matter.

dilap• 8 years ago

he works at formlabs, which doesn't look easy and DEFNLY doesn't look boring!

he also does carpentery and neat plotter art.

pretty impressive guy. very inspirational!

beaconstudios2• 8 years ago

my money's on him spending an hour or two every morning or evening, when the family are still in bed. I've learned recently how much more productive you can be by spending small time consistently compared to large time inconsistently (ie starting new projects full of excitement).

tbrock3• 8 years ago

It takes me an hour to even ramp up with all the context for anything of value... color me impressed.

ryandrake2• 8 years ago

Having a daughter helped me to learn how to be productive in 15 minute chunks, rather than needing a block of hours to “get into the zone.” It’s a skill like any other—learning to work productively without the zone.

This is probably also why open offices and a afternoon peppered with meetings doesn’t bother me. I don’t need 30 minutes of quiet just to ramp up and start working on something. Thanks, fatherhood!

swalsh3• 8 years ago

My son get's up at 6am, i'd have to get up at 4am to get 2 hours of productivity in the morning.

k__• 8 years ago

One of my professors would work two jobs, have two kids and do a major amount of side-projects at university.

He told me his secret was that he only needs to sleep 5h a night.

gameswithgo4• 8 years ago

It is really hard to do deep work with kids, unless you have a spouse who is willing to do 100% of parenting and house upkeep, or can afford a nanny

Keyframe2• 8 years ago

We're expecting our first in December. Is it really like that? Don't scare me man, I have big plans!

gavanwoolery2• 8 years ago

I have a kid, a dog (that needs to be walked 2x per day), a fulltime job, I workout at least 3-5 days per week, and spend most of my weekends doing construction, but I still make slivers of time for my side project. (FWIW) :)

Sharlin• 8 years ago

The nuclear family concept of child rearing is awful. Humans did not evolve to raise kids in isolation from the extended family and the other adults of the tribe.

moron4hire2• 8 years ago

I have two young kids, one 2.5 years and one 10 months. I have a full-time job and a lawn that needs to be mowed every week. My wife and I split childcare and house chores pretty evenly. I still manage to work out 2 or 3 times a week, run semiweekly meetup, and work on a side project or three, and get a full 8 hours of sleep every night.

What I don't do is hang out in bars or watch sports on TV. You have a lot more time per week than you think.

test6554• 8 years ago

Grandparents are the best babysitters!

guildan• 8 years ago

What I find is really helping is if one of the parent is at home. You can do so more things that way during family time and personnel time. Oh sure you say goodbye to restaurant, travels and other "expansive" things, but it's really crazy how I prefer that lifestyle.

It helps that I commute too so I have some free time for leisure, so back at home I don't need/want to pass as much time on "wasteful" activities.

Rattled• 8 years ago

I don't know how old your kids are, but if they're younger than 3 it gets easier. Never is extreme, you will surely have time for side projects at some point, but if you really care about it make it a goal to be part of your working day. That could be by expanding the scope of your current role, or cutting your working week to work for yourself a few days a month.

nomel• 8 years ago

Maybe it doesn’t matter.

Having a few people pass on me the last few years, and realizing I missed my first kids early childhood from poor work/life management at my dream job, I don't think it matters.

You'll never eventually regret spending time with someone you love, but you may regret that writing <some program> made you miss out on that time.

Maybe I'm getting old, or just burning out, but my kids are quite literally disappearing in front of my eyes, slowly turning into young adults. Trading them for some cash and some now obsolete product/device seems less and less "worth it".

I'm not sure where that balance between myself, my kids, and money is, but it seems like a "pick two" type scenario, but in this case you have one short chance before the kids are no longer kids.

freedomben• 8 years ago

Recently felt this way. I looked at my 9-year old and thought of that tiny infant baby with a quivering lip and helpless cry. It seems like only yesterday he was being born.

Also had some friends pass as well. One good friend from work committed suicide. Workplaces have a way of forgetting all about you, and what you accomplished, but family (and friends to some extent) don't. It's human relationships that really matter in this life.

Don't miss out on your family for work. It may seem like a good trade, or simply what you must do, but in the end you'll regret the high cost.

nvusuvu• 8 years ago

I've got 5 kiddos. I use silly traditions/rituals to bond with them. We play a nightly game of ball tag. We have a couple of foam balls we throw at each other for 2-5 minutes. Its frantic and we all love it! We've made up all sorts of rules (Calvin-ball style) to go along with it. Afterwards, I tuck each of them in, the girls want hugs and kisses, the boys say they don't, but I know better. They usually get wet raspberries if they resist!

Other traditions: Family Home Evening on Monday nights. (Rotate through the family members on whogets to lead a simple spiritual lesson. Even the 5 year olds get a turn and love being the center of attention.)

Friday night is movie night. Some cheesy Disney movie from the 80s fit the bill most of the time. Lately, the kids have been asking for the movie Bedtime Stories.

Sunday afternoons are board-gaming time. The kids pick the game.

TaylorAlexander• 8 years ago

I am one of those people who is very productive with side projects. I operate a YouTube channel and website and I design 3D printed robots which I am building all the time.

It does take a lot of energy. People often are surprised I can do it, and say “ah you must not have kids”. Which is true, I don’t have kids.

And I know that having kids means devoting a significant amount of your attention to them.

Still, I feel like I will continue to crank out new projects even once I have kids. I’m sure my time spent on those projects would drop, but I doubt I’d stop entirely.

I have friends who have no kids who don’t work on projects like I do. I think some people are just wired to churn and others aren’t. I have a friend who struggles to get much done on weekends, while I am kind of non stop moving. I think it’s a personality thing.

minor3rd• 8 years ago

I am kind of non stop moving. I think it’s a personality thing.

Yeah, I know people who are like that... I'm not one of them. I certainly can get obsessed with an idea or project and go nuts on occasion, but a lot of time I like to "just chill" on the weekend. Play some computer games and guitar, go on a bike ride or hike, etc.

treespace8• 8 years ago

Since my daughter was born, I no longer have free time for meaningful side projects.

She is almost 9, and I measure my free time in minutes.

What I do have is: - A great relationship with my daughter - A great relationship with my wife - A daughter who is kicking ass in every area of life, and is having a fun, enjoyable childhood. (Unlike my own) - I have not missed out on a thing. I have no second thoughts on my parenting. - I sleep great - Stress free home. - Homecooked meals everyday. (We both cook)

There should be tons of time in the future for me to go back to side projects. But the time I have to raise a family is limited.

basilgohar• 8 years ago

It's truly a blessing to be able to have this kind of perspective. I think a lot of frustration with one's current situation has little to do with the situation and much more to do with the perspective applied to the situation.

tbrock3• 8 years ago

This is a life worth living, thank you for the perspective.

cookiecaper3• 8 years ago

Yes, this. Childhood is fleeting. It's a cliche that you can't really appreciate until there's a big disparity between the age you feel like your kid should be and the age they actually are. It's crucial to capture those moments. We should all do more to ignore anyone who implies that the time would be better spent struggling against a compiler.

exikyut3• 8 years ago

Thanks for using that few minutes to find this spot to reply, and sharing the insight you did.

Now I just need to learn how to find myself in the little things. I think that's what I need to do in order to sustain motivation and engagement. Not sure though, still working on it.

jpfed• 8 years ago

She's not going to need quite as much attention when she's in elementary school, and much less attention when she's in high school.

When she is in high school, starting to pull away from you, I hope you can look back without regret about how you chose to spend your time.

In software development, we talk about context switching in humans like a cache that might take 30 minutes to warm up. But just as a computer has many levels of persistent state, so do humans. It's not a perfect analogy. And this isn't going to be what you want to hear. But speaking as a fellow dad, this is what I did and what I wish I'd done sooner.

Take your todos- your plans about side projects, open source contributions, everything to do with coding other than your day job- and evict it from your mental cache, put it in a swap file, archive it to tape. Keeping that stuff fresh in mind is wasting space that could be spent on what is needed now.

I have a stepdaughter, a son, and a daughter. I wish I could have been more present for my stepdaughter. I wish I could go back in time and hold my then-toddler son. At least I'm here for my daughter.

Years from now, all my kids will be grown up enough that I can work on side projects. As much as it would be cool to write a game or a programming language or whatever, I don't want that time to come too soon.

fogleman2• 8 years ago

Fogleman here. Funny to see an old project in the #1 spot (again?).

I hesitate to comment about this being productive while having kids thing, but some people seem to be implying that I must never spend time with my kids. It's far from the truth. A week ago my son (age 5) and I went camping in the backyard. Coincidentally, he and I have just recently started playing the real Minecraft together on our own private server - every evening lately. (I had never actually really gotten into the real Minecraft before, believe it or not.) We've been playing lots of Thinkfun games like Rush Hour and Shape by Shape. I actually still lay with my son while he falls asleep every night. My daughter (age 7) and I walked to the playground and played for a while there yesterday. We go out and check my vegetable garden daily, and my daughter likes to play "baseball" (plastic bat and ball) in the backyard with me. I work from home currently which is nice because there's no commute and I can see my kids a lot. We have "dance parties" in my home office where there's lots of open floor space. I could go on of course.

I fully understand the sentiment that time is short when it comes to spending time with your kids before they are grown.

There are plenty of folks without kids who aren't super productive too - so the whole thing seems a false dichotomy to me.

Frankly I don't even feel like I work that hard. Maybe "hard" is the wrong word. A lot of people are constantly busy and have no free time. Yet they don't seem so productive? I'm the opposite of that, somehow.

I know I'm under no obligation to defend myself - but there you go.

brookhaven_dude2• 8 years ago

So how do you pull this off? How much time do you spend in coding side projects? What do you do when your kids try to grab your attention during that time?

sbjs6• 8 years ago

My personal guess is that most people need "warm up" time to make progress on their projects, the time needed to build up the mental model of the whole domain. This can go from hours to days to weeks depending on the person and the type of mental model. But some people have certain domains where they can just instantly build up that model in their head and immediately begin making serious progress. You sound like you're one of the rare ones that can do this for a large number of domains (3d algorithms, project architecture, database structure, feature interaction). I'm only like that with a few very specific domains and I suspect most other devs are like me in that sense, so we stand in awe when someone has that natural in-built capability. (I think this not only goes for making progress but also learning new concepts, as I have seen other graduate students who can blaze through certain things like Haskell where I struggle as through molasses.) If this theory is true, then you probably aren't spending more than 3-5 hours on projects like this per week, but you're making the same progress most of us would need 2-5 weeks for. Btw I'm the guy who posted your project and emailed you, thanks for coming here to answer our questions and thanks for making such a cool project and making it freely available for all of us to learn from!

lomnakkus• 8 years ago

If I were being pithy, I find that when you're doing this type of thing it's more a feeling of "working fun" rather than "working hard".

(Of course this means that one is probably not always going to do "production ready" things, but it's for fun, so it doesn't really matter. Sometimes it's fun to just go nuts and sprinkle "undefined"[1] all over the code base and just go from types to implementation as fast as humanly possible.)

[1] This is a Haskellism, but basically means any of:

    assert(false)
    throw new NotImplementedException(...)
    ???
    etc.

EpicEng2• 8 years ago

But from a time management perspective... just how? I have one child (4) and work a day job. It's all I can do to find time to exercise and have an hour or two for myself at night. Do you exclusively program in your free time?

S_A_P• 8 years ago

When I first read this, I read it as a compliment to your productivity, but I totally see how you could read that as someone taking a shot at you. I applaud you for this, I read your gist, ran the commands and went from learning about it to using it in less than 5 minutes. Well done. My son loves minecraft, I hope to use this as a spring board to learning how games like this are made. He's 10 and has the aptitude to write code. I see projects like this and Im reminded I need to keep learning and that writing the same C# enterprise app code over and over again is the reason Im not "inspired" to have side projects anymore...

rom1v• 8 years ago

Hi, I just looked over your github repos, the number of "high quality" projects is impressive. Great job!

satoshinm2• 8 years ago

Thanks so much for creating these side projects, I've always admired the effective simplicity yet functionality of your code, especially Craft. Glad to hear you are as efficient with time management/life as your code :).

For anyone interested, last year I've taken fogleman's Craft and ported it to run in the browser using WebAssembly and emscripten: https://satoshinm.github.io/NetCraft/. It can be used with a Bukkit plugin to provide an interactive web-based interface to (a small section of) the world in Minecraft server. Have not worked on it recently, but could be a fun project to develop further, for all the open source contributors out there. I tried to merge most of the open pull requests and other forks of Craft, but life has gotten in the way...

presscast• 8 years ago

I'm more interested in how you manage to be this productive. Any tips on managing time and projects?

userbinator• 8 years ago

You're literally an example of a "10x". I have a similar experience --- it doesn't feel like you're doing a lot, but the vast difference becomes noticeable if you compare. You can get more things done in a day than others can in a week. That's just your natural ability. Enjoy it.

Waterluvian• 8 years ago

I just assume that the 1-3 hours a night I find to watch Netflix and scroll Reddit is the difference between me and those who hit front-page of HN. If I consistently used even half that time to hack around and learn new things it would really add up.

deepaksurti• 8 years ago

Just want to say: "Fogleman, you are my Hero :-)". In my last interview, when asked who are the engineers that have inspired you, I mentioned your name!

Thanks for all the inspiration, keep it up.

Aside, yes there are a lot of false notions going around and good to have engineers like you to prove otherwise!

konsnos• 8 years ago

Hey, thanks for sharing your perspective. Father of a daughter here (1y) and expecting one more in a few months. I was always wondering how I could keep doing my Arduino and Raspberry Pi hobby projects while growing up a child but somehow it works, even at a slower pace. Sure I don't have as free time as I had, but I find these rare moments in a week and I take advantage of them. Having a great, even full time, job also helps as I changed my last very stressful one that hogged my time.

GLjEI4YbnGD27LB• 8 years ago

Dude, that just means you have a really good thing going.

douglaswlance• 8 years ago

Most people waste hours and hours every single day on all types of mindless activities and wonder why they can't get anything done.

sigi452• 8 years ago

Still impressive.

Looks like you can focus well and have stamina.

How do you keep motivated doing such a project for fun in your spare time?

Do you work 40h/week?

z3t4• 8 years ago

Programming can be very relaxing, you forget about the real world for an hour or two. If you have children you can take turns. And let the kids get used to fall asleep alone, it will feel like torture at first, but when they get used to it you will get an extra hour of free time every evening.

daeken• 8 years ago

I have an 8 month old and I'm more productive now than I have been in ages, both in terms of side projects and day job.

My wife and I both stay at home and split baby duties roughly 50/50; we alternate nights, then split the day pretty evenly. We also each get one day a week that is free of baby duties, so we can relax.

I usually tend to use her naps as an opportunity to work on side projects, so I get a good solid 2 hours or so every day, plus any time I take after she goes to sleep for the night. These bounded, contiguous blocks of time focus me in a way that I find very helpful for productivity. I'm getting a ton done, spending a lot of time with my kid, and loving it all.

sciurus• 8 years ago

It sounds like you have a very flexible day job.

watwut• 8 years ago

I have found that long hours at work or work that makes you very tired (or is very engaging) are bigger obstacles then kids. If the day job is easy, then you can have own projects in the evening. If the day job is tiring, then you cant.

Kids require your time, but if you share duties with spouse, that alone does not make out-of-work projects impossible.

legohead• 8 years ago

I have 2 kids. They go to bed at 8:30. I stay up until 11, which leaves plenty of time to do my own stuff. I am usually too tired though and watch movies. Plus I still need to pay attention to the spouse :) But occasionally I work on my side projects/ideas.

originalbryan2• 8 years ago

I've got twin 3 year olds. Took a while to accept the fact that I have no time to do "things" anymore. And like another commenter, I measure free time in minutes. First time I got 30 minutes to myself (9 months into parenthood) I nearly wept.

I'm at a point now that I'm happy to spend time with them and, after numerous false starts (that were crushed by repeat month long illness moving from person to person, random sleep problems/night terrors lasting weeks, etc) have abandoned all outside aspirations. And I'm ok with that.

I do suspect things will lighten up in time. Perhaps I'll entertain side projects one day in the future.

souprock• 8 years ago

Well, he only has two. I have 1.1 decachildren. Most blokes don't have more than ten kids, but if we need that extra push over the cliff...Eleven. One louder.

I managed to be an open source contributer with kids. It slowed down shortly after the 4th and 5th kids (twins) were born, and it mostly stopped when I got to about 7 kids. I maintained Linux's procps package, added Tux Paint features, helped with the OLPC XO, did some Linux kernel changes, and other minor stuff.

I wouldn't say I have a "Really boring/easy day job", but it does offer flexible hours and no expectation of going beyond 40 hours per week, and my commute is only 3 minutes by car or 15 to 20 by foot. (the job post: https://news.ycombinator.com/item?id=17442484)

It helps to be in a place with low cost of living, so only one income is required. That gains back some time.

t0mislav• 8 years ago

Times when you will have plenty of time will come back fast. :( Kids will start to play more alone or with friends, less with parents, soon they will also grew up, and you will remember the days when you were everything for them.

I don't understand how 3d games are written or know what shaders are, so this is complete magic to me, and I'm surprised it's only 5k lines of C code!

diamondo25• 8 years ago

Drawing cubes is basically one of the first things you do when starting with 3d rendering. Shaders are scripts that the GPU uses for translating your input (a cube in 3d data and your 'camera' and some more vectors) to viewport/screen coordinates. You can do a lot with it [0].

The classic OpenGL 1 framework had no shaders and a static pipeline. Its straightforward in doing things but reduces the amount of fancy things you can do. Maybe check out a guide like here[1].

bena4• 8 years ago

Shaders are basically transformations performed by the graphics card. Or sometimes not. It gets real vague at times because like a lot of things there are no hard lines.

You take a point and figure out if it needs to be colored differently based on certain criteria. Like if it was in shadow, or if it's being hit by a bright light, or you just want a sepia tone across everything. You can even shift everything. Take the screen and distort it according to some kind of function. Like make it all wavy.

3d games are no more or less conceptually different than 2d games in a lot of regards. There are more things to track and be aware of, but you're effectively doing a lot of the same things.

If you've ever messed around with making 2d games, you can even begin simple experimentation by just making another layer of depth. Like LittleBigPlanet, it's ostensibly a 2D game presented with 3D graphics. But it allows you to shift between 3 layers to give you some depth.

gameswithgo4• 8 years ago

Or sometimes not.

No, shaders are always done by the 3d card =)

_bxg12• 8 years ago

Very cool. The beauty and draw of Minecraft have always come from the way it emerges from such simple elements. Reimplementing it in any language would be quite fun, I'd think. It's almost the new Doom.

ilaksh• 8 years ago

As someone who built a Minecraft-like project (but I was careful not to call it a Minecraft clone because it was missing many core features) in JavaScript several years ago and a fan of actual Minecraft, I feel I need to say something.

This is not a Minecraft clone. 99% of the projects out there that claim to be Minecraft clones are not close enough to be called clones either.

The real draw of Minecraft comes from a number of core features, most importantly the crafting and the survival needs that motivate the crafting and building. Minecraft would not have become a hit if it was just a creative sandbox alone. This project has neither of those aspects of the game. Another thing missing is the diversity of biomes. And another thing-- all of the underground features like caves and mines are missing.

So it doesn't have Mine or Craft, don't call it a clone. You wouldn't call something an IBM clone if it was missing core features of that computer.

I think people do the part with just the blocks and rudimentary generation and call it a clone, it's almost like they are giving themselves credit for recreating Minecraft when they haven't even implemented 1/3 of the features, and they didn't even recognize the most important ones.

jklinger410• 8 years ago

So it doesn't have Mine or Craft, don't call it a clone

It does both of those things. You can mine blocks for resources and then make new blocks out of those resources.

Your other points may be relatively salient, but a beta/alpha clone of a game does not have to implement every feature for it to be a clone.

It seems like you've taken this too seriously and really did not need to say anything. It's not really a productive point.

Say you've managed to brow beat OP down to calling his clone something like "A Minecraft-esque Resource Building Game." What have you done, at that point? Nothing. Calling something a Minecraft clone might be sensitive for you, and others, but it does not automatically make that sensitivity valid in any sense just because you feel it.

Unknoob• 8 years ago

The real draw of Minecraft comes from a number of core features, most importantly the crafting and the survival needs that motivate the crafting and building.

Minecraft became big way before survival. I remember playing for hours on Classic just building stuff with unlimited materials and talking to random people about their buildings.

Just go to any creative mode server and you will see that crafting/surviving is just a minor part of the game.

_bxg12• 8 years ago

I didn't realize there were major features missing from this version, and I understand your desire to defend the integrity of the hard task you did yourself

But also, this is just a cool project, and you could probably stand to chill out a bit and just enjoy that fact :)

Zimahl• 8 years ago

The real draw of Minecraft comes from a number of core features, most importantly the crafting and the survival needs that motivate the crafting and building.

Playing on my own, I thought the same thing. But then a coworker hosted their own server and we had probably 12 people playing on the same map. It was amazing what each person was doing. Some built elaborate structures, some farmed, some raised animals, some cleared caves/mines. One guy would just dig - long straight tunnels, he mostly banked all the stuff he mined. Watching my young nieces play the game (not on the server with my coworkers), they simply enjoyed the free-form creative mode.

The glory of Minecraft is that it's so many different games to so many different people. If you like the survival aspect, that's great, but that's not how everyone plays the game.

Karrot_Kream• 8 years ago

For folks who want something a bit less pedagogic and more fun to play as a game, I highly recommend Minetest [1] which gives you a programmable layer on top of the base Minetest engine to make Minecraft-like game modes.

This is very cool. I got it build/running in < 3 minutes in Linux.

My boy love Minecraft. I like to use this as base to teach him more about programming.

Any suggestion on small projects that can be addon / mod use this code as base.

I am thinking a series of coding exercises that can be hack/add on to this:

Add a command/mod to:

1) Draw line, Square, Triangle. 2) Draw Circle, Ellipse, Cone, Cylinder 3) Build Car, Airplane 4) Build Space Ship 5) Putting picture of his own face on the block.

... Any other suggestions?

Each small projects take about 1-2 hours build on skill sets that learn before. It should be simple and fun to do with goals of encourage kids to learn programming.

My boy finished all the CS classes in Khan Academy and seems to enjoys them.

If anyone else has strong interested in this, I will see if I (we - group of us) can develop this as a new Khan Academy CS class and contribute it to KA.

Try running server.py locally.

Then check out builder.py which will send commands to your server to change blocks. You can rapidly build all sorts of shapes with a few function calls.

I actually compiled this project to Emscripten a few years back:

My 5 year old kid is addicted to minecraft and there is no way to prevent violence (you can always keep killing animals even in Creative + Peaceful mode). The problem is that 5 year old have little context on consequence and they really get intrigues in exercising new power they have. I'd like a pre-schooler mode which actively discourages any violence. May be if you try to kill something, an alien would descend and take away all your assets. So only thing you can ever do in Minecraft is just build something :). If someone can add this feature, it would be AWESOME!

On Zelda you have little incentive to attack the Cuccos (chicken).

MineCraft also has incentive: you get meat when you kill animals.

If that sort of thing bothers you, I'm not sure it's possible to make a version that totally avoids it. Even breaking blocks is "enjoying destruction". I certainly enjoyed smashing all the bricks in Mario when I was little.

That said, I suspect most 5 year olds can figure out that virtual cube pigs aren't real, and that there's no consequence to punching them with virtual cube arms.

You might want to try the free game Minetest [1]. It is very similar to Minecraft but the basic version, minetest_game, has no animals. You can add mods that give you animals if you want them but they are not necessary. There are hundreds of open source mods to choose from or you can write your own mods in Lua. I learned Lua by examining the mods that come with the game and changing them. You can play in a mode where you can't take any damage. Multiplayer games can enable or disable PvP.

This has a much brighter future than Minecraft on Linux or Mac (completely neglected after Microsoft acquisition).

I'm assuming this runs about a jillion times faster than actual Minecraft? They should re-write minecraft like this; its performance has always been so awful.

They did. These days “Minecraft” officially refers to the new version, while what you are talking about is called “Minecraft: Java Edition”. As of now, both are maintained, though people are afraid that Java Edition is being phased out in favor of the new one. Main reasons for people preferring the Java Edition is modability and availability of an official server software for self-hosting.

I am in awe at how the executable is less than 1mb to download.
