nvm. One little pole did the trick
davewasthere··on Show HN: Neil the Seal Game
I can't blow up the servo, even though I've totally wrecked it.
davewasthere··on Canada plans 'nuclear renaissance' with up to 10 reactors built by 2040
One thing we're not short of here in Australia is space. And sunshine.

I'm not opposed to nuclear in the mix though. It's pretty incredible. And the South Koreans have done a pretty awesome job in the UAE with their reactors it sounds like.

If you're comparing nuclear reactors with solar panels though (which is tricky), depends which metric you go for. If total annual output? Then up it by almost an order of magnitude. 100km2+ would be needed to produce the same annual output as a 1GW at 90% nuclear station.

But we've a ton of land, so it makes a lot of sense.

davewasthere··on Ask HN: What trick of the trade took you too long to learn?
The fact that there's an entire country mostly unaware of the utility and ubiquitousness of a simple electric kettle, blows my mind. But then again, I'm a product of the Empire (British) not a North-American.

But while the idea of using a stove top kettle (have done so in the past) is fine, the thought of using a microwave to heat up a cup of water for tea seems abhorent. (although it's really not)

I guess it came about because 110V not being as efficient? Or more American's are coffee drinkers?

I don't know about you, but I'm skeptical.

davewasthere··on Show HN: I convert videos to printed flipbooks for living
And limited run it. So it there are XX orders already, then the youtube video is delisted, so only exists in paper form.
davewasthere··on Magic/tragic email links: don't make them the only option
And worse (sometimes) consumed by email scanners. There's all sorts of hassles with them. Email deliverability often an issue too.
davewasthere··on DOOM CAPTCHA
I learned I can't play Doom if I can't strafe. I'm a bot!
davewasthere··on Ask HN: Great maker projects for 8th grade kids and above?
Not quite the same, but if you've a leaf blower, then making a hovercraft with a couple of pool noodles and a circular piece of plywood is pretty cool (and a lot of fun).
davewasthere··on Ask HN: Sci-fi recommendations by non-western authors?
Hiroshi Sakurazaka wrote 'All you need is kill', which became Edge of Tomorrow film.

And, while not SciFi, I think Haruki Murakami's books are worth a read and might scratch and itch you didn't realise you had. Start with Norwegian Wood if you want a light intro, but then Windup Bird Chronicle next. Possibly 1Q84 after that?

davewasthere··on Show HN: A free minimalist daily habit tracker
Quick bug.

As an unauthed user, add a habit. Then log in. Habit has disappeared. (but can create habits, which then sync just fine to other devices)

I guess I was expecting my unauthed user habit to persist after logging in.

davewasthere··on Shattered Pixel Dungeon is an open-source traditional roguelike dungeon crawler
original creator: https://twitter.com/watawatabou

Was always free... now people have gone to town with the source code.

davewasthere··on Religious 'Nones' are now the largest single group in the U.S.
Now they just need to organise effectively.

But how do you organise a disparate group whose only common characteristic is that they don't believe in imaginary deities?

davewasthere··on Some Pixel owners still can't dial 911 during an emergency
Had exactly the same thing in Australia when trying a 000 (Australia's emergency number) call with my Pixel 6 Pro after watching somebody run off the road and smash into a pole.

Fortunately I had the local police station number and was able to call that just fine, but not until a few failed attempts at the real emergency number.

That said, another good option is attempting to call 112. Which is an emergency number in many countries. (Works in the US too).

But yeah, it's not good.

davewasthere··on Ask HN: What's the coolest physical thing you've made?
A small thing. I made some braised bronze chess pieces. https://photos.app.goo.gl/rN3xkgxybeY7WP9K9

Was really happy with the design, considering I just made it up on the spot. I had previously carved a few chess sets before though out of wood.

davewasthere··on Show HN: 77 Year old launches SaaS platform today. Seeks feedback
Although it reads as though it's $1 ea for your first 100 homes you sell, then $995 after that.

And actually, probably need to make it $1/home for the first 1000 or so just to get the site to critical mass. Not going to get many buyers for 2 listings...

davewasthere··on How I Experience Web Today
Thank you for this. It's almost a perfect template for a site I'm working on. Even had a few 'features' I'd forgotten to include. /s

Now be meta and build GPT with GPT.
davewasthere··on Ask HN: What's your proudest hack?
In 1997, I had to convert a legacy unix (SCO System V?) application's comms from X.25 to tcp/ip. Had the source code, but it was a weird case of the system you built it on didn't have a networking stack (or was somehow massively different that it was a pain to build and now unsupported) and while I'd written some basic networking bits (some telnet utils etc) in C on windows, but felt like this was a bit of a stretch of my skills/abilities.

Anyway, after playing around with different flavours of linux, I ended up with a rather simple solution that ended up being easy to install. Essentially it was a two line script that piped the serial port to the destination server IP address, and inbound tcp/ip piped to the serial port.

So just plugging this little (old school) 486 box in-between the serial port on the legacy system and an RJ-45 connector which plugged into the 'corporate' network and we not only had an upgraded comms layer, but we now had remote system management, which we never had before.

Think it saved $250k+ minimum replacement at next to no cost. Just me barrelling up and down the country installing the new hardware. Was a fun project in the end and started me down the linux appreciation route.

davewasthere··on Ask HN: What would you do to turn $100K into $1M in 3 years?
Casino. All on Black. Repeat 3 more times (hoping your luck holds out for each). 16x in under an hour. (or zero most likely... but definitely lowest effort) I don't recommend this approach however

But yeah, if you're talking USD, then one could easily live comfortably for five years in Vietnam/Thailand for $20k/year. (Although you could easily live in a ton of countries if you pick your town/city/area correctly) Then smash out all those side-gig bootstrap ideas that come to mind. If you can build MRR of approx $6k, then you've effectively built up the equivalent of $1M earning 7% in the bank.

Actually, my latest company was started 3 years (and nearly a month) ago, and is now earning easily that in revenue from one of its Saas products, so yeah, it's definitely acheivable.

davewasthere··on Show HN: Open Source Authentication and Authorization
Pretty awesome.

SLA Guarantees is spelt wrong: https://supertokens.com/pricing

davewasthere··on How I learned about corporate firewalls
I had exactly this.

We run a Saas and someone wrote an email saying that our server was down, and when we'd expect it to be up. Not having had a notification, I double checked from a couple of geographic locations that our application was indeed up and responding.

After a bit of investigation, it turns out that they have to whitelist every unique address with their corporate IT. And had only whitelisted our primary client-app URL (talks to a couple of different API endpoints), hence the strange error message.

It's been a long time since I've worked somewhere with whitelisting.

The value of that deposit would be reflected and transferred.

It was a great way to earn money as a kid in the 70s too. Wander around and find old beer/coke/milk bottles and return them for the deposit.
davewasthere··on Picking up free lithium cells off the street and making them safe for use
How about get rid of one cruise ship, and maybe just the Italians stop driving? /j

Yeah, Cruise ships are pretty nuts!

davewasthere··on I stopped to watch kids playing at recess – security was called
Wow.. And if you asked me to predict the outcome of that incident, I'd have said the fatalities would have been the other way around... go figure!
davewasthere··on How many Linux commands can a 7 year old learn?
I think it's pretty cool Vasa was up after 10pm learning cool stuff with his dad.

Recently got my daughter into doing web application testing. She found four bugs in an hour. Trying stuff that I never thought of. I've created a monster. (She's getting paid, don't worry)

davewasthere··on Ask HN: Share your personal site
Wow.. So many great sites.

Mine are: https://www.davewasthere.com/ travel site I created after getting locked up in 1999 while travelling in Russia. I stopped updating in in 2014, and stopped travelling in 2019. No idea why ;)

And https://davebeer.com/ as just somewhere to write random shite, with no real theme.

Just good fun and neither have any real purpose other than a semi-public, but obscure diary.

Looks great on desktop. I reckon it could do with a tiny bit of work to make it play nicely with mobile though.
