Show HN: I built a(nother) house optimized for LAN parties (lanparty.house)

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]:

> If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos.

Hopefully I did that?

Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub:

Anyway, if this shouldn't have been Show HN, I apologize!

I think these are cool and seeing the NetBoot + CoW setup for gaming is fun.

Thanks for sharing!

Do you run Linux or Windows?
The server is Linux but the game machines are Windows.

But I am going to try switching the game machines to Linux at some point. I can't tell you how many times I've run into what were almost showstopper problems with the whole iSCSI netboot thing with Windows, only to get really lucky with some registry hack that worked around it. I'm sure it's going to just stop working at some point. Whereas with Linux I can dig into the stack and make things work however I want.

In fact, in the old Palo Alto house, when I first completed it in 2011, the game stations were Linux for the first six months. In theory it was a better setup because the machines were able to use their local disks for the copy-on-write overlay (this was easy to set up with an initrd script and Device Mapper). With Windows, I haven't figured out how to utilize the local disk at all -- so all the copy-on-write overlays are on the server side, which of course wastes server resources.

Of course, the problem with Linux is game support. We got a long way with WINE in 2011 but there were just a few too many issues. Here in 2024, Linux is ostensibly a much more capable gaming platform, with Steam support, Proton, etc. So maybe it'll work better this time?

Anyway, just another project on the todo list...

Have you thought about using Clonezilla and broadcasting out an image using PXE boot?

Would completely bypass the iSCSI setup, and each machine would still get the latest image from your server before the lan party begins.

A really neat thing about the netboot setup is it takes zero time to clone the image to all the machines. As soon as I'm done installing updates on one machine, I shut down, run one command that completes instantly, and now I can boot all the machines immediately with that image.

There have been a decent number of times when I actually did this during a party to fix an issue, or between parties just to keep the machines maintained for the family to play with, etc. It'd be hard to do that if I have to spend hours transferring a large image every time.

Aside from the stability issues at boot time, there isn't really a down side. I don't have any problems with load times. So I'm pretty happy with the setup.

With multicast, you only need to send the image once to all 20 machines. With 10 gig Ethernet, a 1tb image should be sent in approx 15 minutes.

Also, maybe having a steam cache server and using the local disks as a game store might help with installation of games?

Definitely can see the benefits of the netboot setup, though!

How much does it cost? Probably can only be pay be Musk, Wall and Gates
Nope, USD 150k (for stations & cabinetry): https://lanparty.house/#cost
Fake news.

> The house overall was a 7-digit number. Sorry, I'm not comfortable being any more specific than that.

You can get that size of home for 2 million in Austin. The work to make it a LAN party home is not that expensive in comparison. The magic for him is that his dad is an architect. The home is very well designed and if you want that kind of design you’ll be paying more. Especially if you want the whole thing ready built.
> The magic for him is that his dad is an architect.

Yes. I could never have done any of this without that fact. When you hire an architect, especially for a high-end house, they are incentivized to make expensive design decisions in order to make the house more impressive for their portfolio, and of course the contractor is not going to stop them because they want the money. And if you're just a normal person not experienced in homebuilding, you will not be able to spot what they're doing. I'm sure I would have been taken advantage of if the architect wasn't a family member.

Not just those, but probably not too far off, either.
This is super awesome, congrats!
So we have an ongoing debate in the white collar world - work in the office or work at home. I am firmly on the “teams work better in physical proximity camp” but there are still many better ways to arrange that physical space

And this - the hideaway desks that fold down to become a table top gaming session, well that could make much more flexible office spaces. (Don’t get me started on offices with one or two desks and doors that shut !)

But yeah, I like it, even if my house has that many people in I would probably just hide in the kitchen all night

Love the creativity and dedication to the project. And really cool house.
Awesome! The fold up mechanism is a great idea to make it look clean, when there is no party and it also saves the hardware from dust :D
Extraordinary home! Great design. Especially love the cat stuff. I have to say, it’s wild that something “moderate” like an i5 / 4070 build is so powerful these days. It’s middle of the line in this era but it’s enough to play practically anything.

Also, this is a classic example of the power of leverage. $200k down on a $1m home, home goes to $2m gives you a $1m profit on ~$240k. Accidental, in this case, but nice.

to see that upside on a home requires you 1. sell and 2. buy somewhere cheaper (or not buy at all) ... Otherwise it's a zero sum game. Home for a home.
Indeed that’s what OP did. Bought in the Bay low, then sold high and moved to Austin, where presumably the increase in value is again sufficiently high because Austin prices skyrocketed in the last 5 years.
Yes! My point is simply that, unlike an investment property, it's often hard to "see" the upside on a home sale. OP appears to have reinvested significantly in the epic new land + gaff, and also makes the point that prices have since been declining in Austin. The fact it's a home means that all this is a bit of an aside to the real transaction.
Yeah OP is winning at life about 10 times over.
What DDR pads are those? Are they custom made?
They are L-TEK Ex Pro X. Shipped all the way from Poland!

They seem to work pretty well. Have been using them frequently for more than a year with no issues yet.

Thanks, those were the main recommendation the last time I looked into it (a few years ago), good to hear you recommend them too!
L-Tek is probably the best option by far that is somewhat affordable.

Definitely penny-mod them too (just remove the panels, tape washers under the edge of each metal contact point - it makes the pads way more responsive and more fun to use).

You can also buy a portable barre bar on amazon, that's what I use. Super stable and easy to stow away. A bar lets you maintain form on crossovers/jumps, and I recommend for anyone not super casual (playing 12+).

Lastly, if you are really serious, you can buy a replica DDR pad from China for about 4-5k, or a used real pad for similar. The arcade feel is much better than L-Tek, but you need a lot of space for these. [1]

Is Stepmania still the go-to DDR clone? This is very nostalgic. :)
To be honest I've been using the same Stepmania 3 installation for decades. Never updated to Stepmania 5 because the step chart format changed and I didn't want to find all the songs again. I have not kept up on recent developments.
What do you use for the other controls? Start, select, exit, confirm... I have an older L-Tek and I really wish I had one with all nine step buttons (for other dance games) plus control button on top. Also kudos for not using a cheater bar :D. I don't see the old-school no-bar playing much anymore but I find it much more impressive.
I have a wireless keyboard nearby that I used to select songs.

Yeah I have never used the bar. Probably because I learned to play at home, starting on a basic foam pad, and so obviously didn't have the bar available.

Hahaha, the anecdote about the subcontractor is great.

What a thoughtfully designed space for your family and friends! I feel like going this custom is pretty rare, and you’re clearly getting the value out of it. I also love that you did the math on the cable runs making essentially no difference.

Thanks for sharing :)

This is super freaking cool. I'm curious how you feel about Austin vs Bay Area in terms of general quality of life, culture, things like that?
It feels pretty similar, but more chill. Distances are shorter. The sky doesn't fill with smoke for a week every year. The weather is much more interesting -- honestly I got really bored with Bay Area weather after 15 years. I even like the heat in the summer, in short intervals. There are enough tech people here to be interesting, but not enough that a random person you meet on the street is likely to be in tech.

One thing I appreciate is that there is tons of building happening. Housing prices went up during the pandemic, but there is new housing being built everywhere you look, and as a result the prices are now going down quite a bit! (Which I'm fine with, even as a homeowner, because I wasn't planning to sell anytime soon anyway and I like to see problems getting solved.) The downtown skyline keeps changing -- the tallest tower when I arrived is now hardly notable!

All that said I'm not sure I personally am very affected by where I live. When I moved from Minneapolis to the Bay Area, people asked me if it was a culture shock, but all I really noticed was less snow and more left turn lanes...

Having lived in the Midwest, Texas and Bay Area I can soundly say there is no comparison which can be made about the natural splendor. Bay Area, even with smoke in the air for a week, is orders of magnitude more comfortable and interesting. In Texas people cloister into giant houses and say goodbye to enjoying nature, it’s really sad that people prefer such a reality. It lets them forget just how grand a world there is worth saving and fighting for instead of letting it all become privatized and exploited unsustainably.
I do a lot of biking, and TBH I've had an easier time finding enjoyable bike routes near my house in Austin than I did in Palo Alto. During the summer I go biking at dawn and it's great, and during the winter there are usually 70-degree days regularly enough.

Of course, on that measure, Minneapolis blows both of them out of the water -- at least during the half of the year when biking is enjoyable.

As a fellow cyclist I find this strange. I visited austin to see what the hype was about and left knowing I couldn’t live there. Massive 6 lane stroads running through suburban sprawl for miles in every direction. Barely any elevation to speak of. Strangely humid despite there being no water in sight.

Most people I know that are happy with the move to Texas from California are the types that never cared for going outside in the first place. It’s a good place to build a big house and fill it with toys, which is exactly what you’ve done, so nice work there!

I’ve never biked in Texas, but the routes even a short distance west from Palo Alto are excellent. You need to be willing to go uphill, though :). LAN party house v1 would have been maybe 15 minutes from where Page Mill starts to get spectacular, not to mention spectacularly steep.

In the modern e-bike era, the hills are more accessible, too.

Oh I biked down Page Mill and into the hills a lot, that was my main bike route. And yes, it was great. But there was really only one part of those hills that was close enough to get to without driving first. In Austin I have a few more options nearby.
I’ve made this same observation which might explain why there is such a divergent world view between people living in different parts of the country.

A neighbor of mine recently moved (back to) Texas. Where we live is 1/4 of a mile from a massive state park, right on the ocean full of mountainous trails. Dude admitted he had only visited it once in 5+ years, but complained about taxes and the price of gas constantly. It’s no wonder he wanted to go back.

Related to culture, I moved to Austin in 2012 and that was the first time I saw a restaurant advertising that their water had no fluoride.
Are people in Austin more concerned about fluoride?
I have never seen nor heard any mention of fluoride in Austin, FWIW.

I mean, maybe I just don't hang out with that crowd. But I do go to restaurants and haven't ever seen it mentioned.

I suspect it will be interesting when people all realize too much fluoride is very bad and isn’t actually disinformation. It’s obviously not an intentional conspiracy to make people dumb but it happens to be outdated science to fluoridate city water at levels we do in the US.
This is factually incorrect. In fact recent studies show that up to 25% of cavities are still prevented by fluoridating water. On top of that, multiple Canadian cities are adding fluoride back in their water after 10 years of having it removed because of excellent evidence that the lack of fluoridation in the water is what led to the increase in cavities in those cities, since they had neighboring cities who kept fluoride in the water during the same period
It's factually correct that too much fluoride is correlated with decreased average IQ.

By "too much" a factor of > 10x western safe levels is meant and by "correlated with" is meant a slew of other heavy metals are generally present.

This comes from studies that look at places in China, in Africa, and elsewhere that have unusally high levels of fluoride and other elements naturally occurring in water or as a by product of other industrial processing going on.

Where the problem lies is in the "fill in the missing line" extrapolations that the anti-fluoride folk do to "conclude" that if really high levels of stuff in water makes you stupid and affects your health then it surely must follow that small amounts make you a bit stupid and a bit unhealthy.

This is despite no such evidence existing even given large western populations with meticulously kept water quality and health records in the UK, Canada, Australia, US, etc.

The G20 recommended fluoride levels are safe by all the evidence to date and work to decrease cavity rates.

What is significant political progress is that such measures are now allowed to be debated if they are justified or not. Western political culture clearly shifted far towards dogmatism and needed a course correction. We shouldn’t be afraid to question scientists and studies.

It is factually correct fluoride can be dangerous and studies have shown that. It is also factually correct fluoride in water reduces cavities. The debate is the risk rewards lines and safety.

https://www.newsweek.com/epa-fluoride-drinking-water-risks-c...

> Federal officials have recommended a fluoridation level of 0.7 milligrams per liter of water as of 2015. This is a decrease from the recommended upper ranger of 1.2 milligrams from the 50 years before that. Meanwhile, the EP has a longstanding requirement that water systems cannot have over 4 milligrams of fluoride per liter of water. For comparison, the international safe limit for fluoride in drinking water as stated by the World Health Organization (WHO) is 1.5 milligrams

The A/B testing you reference in Canada is interesting data obviously. It’s also possible reducing cavities with fluoride comes at an IQ cost isn’t it?

> It’s also possible reducing cavities with fluoride comes at an IQ cost isn’t it?

There's no evidence to suggest that though.

Just evidence that high levels (much higher) of fluoride and other elements in water has an adverse effect.

Beautiful house, great ideas, love the stow-away workstations -- no patch panel in the network rack facepalm
I wish I was rich too.
He seems like he has a really good attitude about it.
I too would have a great attitude if I had that much money lol
(comment deleted)
Wait, why do you have the same living room as Bojack Horseman?
Lol, never seen it before, but looking now, yeah it looks kinda similar!
(comment deleted)
This is truely living the dream, well done mate! It is indeed crazy that cabinetry costs the same as the technology.

How does the cat restroom exhaust work? Always on or does it have a sensor?

Do the cat doors prevent sound getting into the kids' rooms from the living room?

The cat room fans are standard bathroom fans. At present we just leave them on all the time -- you can see the switches taped down in the photos. I suppose it might be a good idea to rig up a sensor...
Might be able to use a flipper zero as the sensor, if the cats are chipped. Then you'll have data to catch any unusual usage, like a urinary blockage, before it becomes a serious problem! At that point you're a smart switch and Home Assistant script away from fan control.
Garply had a blockage once and he did a remarkably good job of communicating the problem to us directly!
As a fellow cat person, I feel pretty confident interpreting what’s being implied here. :-)

Beautiful home and contents, btw! It seems expensive but more than a few folks would have spent the same money on “nicer marble” or something.

Heh, I actively dislike "nice marble" or anything that just looks expensive without providing any functional benefit.
I would recommend to use an TVOC sensor that detects smell very easily and then automatically switch on a fan. Could be a fun project.

Just need: - TVOC sensor like the SGP41

- ESP32 microcontroller

- Electric Relay

Interesting idea. Do TVOC respond with enough signal to low level aromatics verses all the particles from cooking or pollution?
I’m highly unimpressed by my couple of SGP41 sensors, but they would probably work for this application.
I did wonder where the network connections were going into the cat areas!
Constant fans are sucking outside air into your house. Could be part of your Heat/AC efficiency problem mentioned in your post. A timer to run every 10th minute would be a simple improvement.
Yeah that's a good point, I should turn off the fans for a day and see if it changes the power use...
Heat exchangers can ensure the incoming air is heated up by the air going out, at no cost.
We do have an ERV. But I suppose the cat fans don't actually exhaust through it. Maybe we could have arranged that had we thought harder about it before construction...
Sir, I want to add that it was deeply inspiring. While I’m struggling at 40 just being a CEO of 14 people, which by one measure is excellent but I have put aside so many lives for it and failed at all my social ventures (yes I mean friends and dates); You, you succeed to have time for a wife (a potentially intellectually interesting person at that, according to your brief summary), you succeed to build a house, manage a lot of people at work, have friends with proper deep connections, and still have energy for home renovations. It’s like you’re living 9 lives at once. Oh yeah and kids. Like my uncle, who, beyond children, still had time for home renovations to build a cozy nest everywhere they lived.

In this day of international men’s day, maybe I should still enquire about your internal mental health, because stress can be discreet, but still, the outer appearance you give from your allocation of time and clarity of mind seems absolutely perfect.

Well I certainly do get stressed sometimes (particularly when cat-herding at work) but overall really can't complain!

BTW it's not a renovation, we build the house from scratch on an empty lot. :)

A lot of newer building codes require fans to be constantly running anyway due to the other part of the building codes requiring high r-value insulation.
A sensor would be easy enough, there are simple non-smart sensor fan timer that will activate a fan for a programable time.
> [High AC cost.] Perhaps we have too many windows letting in too much sunlight...

My office has automatic blinds that open and close according to some climate control system. The blinds are within the double glazing, so they can't be damaged by weather (or cats). The nice version for a home would be something like [1].

I'm sure the owner could program the automation so they only change position if no-one is in the room. There's no point having sunlight streaming into an empty room.

[1] https://www.betweenglassblinds.co.uk/

Yeah good idea. We do have electric shades on many of the windows... I just need to rig up some software control of them. I suppose as an experiment I could leave them all down for a day and see how much power it saves. The shades are on the inside of the glass, but light-colored, so should reflect back a fair amount of light.
In the winter in a normal European/northern US climate, you probably want sunlight streaming into an empty room to reduce the heating bill.

Possibly never in Austin, TX: I am not too privy to the temperatures it gets down to in the winter, though heating was brought up too.

That's awesome! Unfortunately it's all "request a quote". Can you shed some light on how much you paid?
Sorry, by "my office" I meant the building my employer owns.

There were several companies when I searched for "shutters OR blinds inside double glazing".

The biggest surprise for me was seeing the desks with no mouse pads (or if you wanted to build it into the cabinet you'd probably want to stick down a desk pad).

But I also in my circles everyone takes their own keyboard/mouse/pad/headphones as those are the things it's hard to adjust to - admittedly my priorities could be completely different.

I mostly haven't used a mouse pad in decades... until recently. I now have a mouse pad on my main work desk because the wood where my mouse was kept attracting weird black spots. They were easy to clean off but weirded me out. And I guess it would be sad if I ended up with a permanent wear spot...

But I think the LAN parties don't really happen often enough to cause much wear. In 10 years at the old place no one used mouse pads and it was never an issue.

> the wood where my mouse was kept attracting weird black spots

Have the same issue, but can't subscribe to mousepads. I believe that's dust getting in the crevices of the wood.

Or oils from your hand, perhaps?
Once you get oil, dust, or moisture on a surface, dust starts to build up. It's downhill from there. Hard surfaces are easier to keep clean, just don't leave them damp after cleaning, but completely dry and slippery.

The close folding furniture is probably great for holding back dust buildup.

May I recommend the 3M Precise Mouse Pad with Repositionable Adhesive Backing? Dumb name, good product.

https://www.amazon.com/3M-Precise-Repositionable-Adhesive-MP...

Thank you for recommending the 3M Precise Mouse Pad with Repositionable Adhesive Backing, I might grab one for the office!
Thanks from me as well, I am in fact going to get one of these and if I like it, equip all the stations with them!
Wow, this is beyond badass. Not only is the LAN and home network setup top-notch, that location is excellent too - what a view! Congrats on the amazing LAN setup and such a fun place to enjoy some gaming with your friends & family. Truly worthy of some envy, that's for sure :) Looks like it was a good chunk of work, but 110% worth it!
> Normally, maintaining twelve machines used by random guests would have two huge problems:

Maybe you did this with your other house but I would have thought guests would bring their own computer to a LAN party. All you have to do is provide the space and network capability?

> Jade and I needed a bigger house, but we really could not afford to buy (much less build) anything bigger in Palo Alto.

I’m really surprised about this, really shows how ludicrous the housing market is in the Bay Area. How high does your income need to be to afford a bigger house?!

(comment deleted)
Also considering 1400 sq ft (130 sq m) too small to raise a family is peak American... That's bigger than 99.9% of apartments people live in in Europe and raise a family just fine.
At first, my jaw was open looking at the photos.

Then I remembered… oh yeah, everything is bigger in America (especially in Texas)!

I suppose if you want to raise a family AND have a huge dedicated lan party area, then maybe 130 sqm isn't enough.

But I do agree with you. We live in a 4 bedroom detached house approx 120 sqm and this is plenty of space for a family. In fact, it's above average space out of all the families I know...

I live in what would be considered a large house in the UK and it’s marginally larger than that!
In fact, calling 1400 sq ft a bachelor pad and then complaining about housing is unaffordable there is hilarious on many levels.
The most hilarious level is that 99% of bachelors that I know spend 99% of their time in 1 room.

So they don't really need more than a studio anyway. Nor would they clean/maintain it anyway.

3/4 of Americans are overweight or obese now. We need a lot of room.
1400 sq ft is a large terraced house in London and will cost over 1m GBP (so about 1.4m USD).

Yeah, 1400 as "small" is very US oriented :). But having grown up in the US, I really miss the space of the houses.

One issue with wanting a big house in Palo Alto is that most of the lots there are fairly small. There's not that many lots that can accomodate a larger home, so at best there's not many options, and sometimes there are none.
Not for a reasonable price, anyway. There are some homes that have added basements to get the space, but now we're talking something like $6 million, if not more.
