LeonM commented on Ask HN: What trick of the trade took you too long to learn?    · Posted by u/unsupp0rted

Recently I looked at what it would cost me to move.

First, I would be giving up several acres of land, and my dog and cats would be very unhappy.

Second, for me to get a house with the same bedrooms, housing cost would almost DOUBLE, and on average it looks like I'd lose around 800sqft.

I've been here for more than a decade. Moving would cost us a TON of money for no gain. (If we went to buy another home)

And that calculator also agreed (on rent not being viable, either!)

> I've been here for more than a decade.

I think that is where the difference is.

The buy-vs-rent discussion is more aimed at first-time buyers. If you already own a property that is largely paid off and has had the benefit of appreciation over the time you owned it, then yes, it may be more beneficial to keep the property, as you have seen from the calculator.

If the answer was always that rent would be cheaper, then the calculators wouldn't have to exist ;-)

> housing cost would almost DOUBLE

Except that you will now have the profits from selling your previous property, which you can invest. That investment payout can partially or even completely offset the cost of renting, which means your monthly costs will be much lower.

Say you make 500k by selling your house, and invest that against 6% ROI, then you make 30k/year passive income, thats 2.5k/month. So deduct that from the rent you'd pay and compare again.

Other languages have all sorts of oversized arrows, like ==> and >>>.

-> in PHP and C++ looks clean by comparison.

I'll never forgive them for the brain fart they made of the namespace separator, though.

You mean the backslash? What's wrong with that?

Just to clarify: I can’t use the wired USB-C Apple headphone adapter with this?
LeonM · a month ago
The data and PD communication are both working (that was the majority challenge on the EE side, shown in his video). So it would depend on the capability of his solution to let the phone work in host mode, thus being able to provide power to the adapter.

Though I'm also not sure how the MFi situation is with those generations of iPhones, and what restrictions Apple has built in to the OS. I haven't worked with MFi for a while, and I don't know for sure if MFi chips are even required anymore for that generation of lightning devices, or whether the author has incorporated one.

EDIT: I just saw this on his website:

> Any other accessory that requires power from the phone is not compatible.

So no, USB-C to headphone adapters won't work, they need power.

How does he have so much equipment? That’s way beyond a hobbyist!
LeonM · a month ago
Either he had some money available, or he just financed. It's not that hard to get a small business loan/financing for this kind of equipment.

I don't know how many he sold, what his production capacity is, and what margin he makes, but I recon he could definitely make his investments work from the sales of the cases alone. And even if it does not, then there are also future products that this equipment enables. So a good investment if you ask me.

Self hosting email will always be niche and frankly it was pretty niche in the noughties too.

I do find that if you carefully curate an IP address ... now that's the real problem. Most IP blacklists aggregate and generally end up roll up to cover entire AS ranges and allocations instead of actual individual perpetrators. However, if you can grab a "corporate ISP" static IP address, you are normally OK, at least in the UK.

Then you need to get a reverse DNS entry sorted out, although this only bit one of my friends recently after five years of not me not bothering. rDNS used to be rule one in anti spam. Oh well 8)

Modern (lol) email systems generally look for SSL/TLS and SPF, DKIM is nice and if you have DMARC then you are clearly a jolly good chap. Then they have a ... rule set, some of which are as old as my email management experience and some of which are down right odd (and probably based on Bayesian learning)

Anyway, email self hosting isn't impossible. Anyone who claims to be a nerd really should be able to manage it ... 8)

I don't want to live in a world where self hosting is impossible. It'll be the same one where I don't own a drill-driver and that would be bloody weird.

LeonM · a month ago
I work in the email industry, so I might be a bit biased on this one, but in my experience self-hosting email has actually gotten better, or at least for the outbound part, funnily enough. But I won't go into why IP-reputation is a thing of the past, for the risk of having to write a very long post that'll be downvoted anyway.

The biggest problem that I personally see with self-hosting, email in particular, is that most resources you find online are outdated, based on superstition, or simply plain wrong. There is a lot of heated debate around running email services, and many bitter comments from people who tried once and got burned.

Self-hosting a personal email service, or any kind of service for that matter, isn't impossible. The internet is still based on free and open standards (the RFCs). But it is free like speech, not beer. Running your own services will cost you resources. Most of which is your time, but some may also be money (for example: ML-capable hardware, certificates, licenses, etc.).

You'll have to be willing to learn, and more importantly: willing to accept that it is a lot of work to setup and maintain any self-hosted services, not just email. You have got to be willing to read through the RFCs, study the errata, read the documentation of your software, be willing to spend time in configurations, being sure you understand your settings, set up lab environments to study both ends of the service (for example: the inbound and outbound service in an email transaction).

Self-hosting is a great learning experience, a fun hobby even if you enjoy such things. It'll allow you to explore all sorts of tech throughout the entire networking stack. But due to the amount of work it takes to setup and maintain, it'll never make financial sense to self-host, at least not in a professional setting. Cloud-hosted solutions, email being a good example in particular, have the benefit of scale: they are dirt-cheap and work really well. It makes zero financial sense to self-host any email service beyond personal use. Unless hosting is your core business, don't be tempted to self-host anything, focus on your actual business instead.

LeonM commented on Show HN: Ten years of running every day, visualized   nodaysoff.run... · Posted by u/friggeri

I haven’t aggregated the trend over time, but my resting HR has definitely decreased, I’m roughly around 40bpm at the moment, down from ~60bpm 10 years ago.

> I’m roughly around 40bpm at the moment, down from ~60bpm 10 years ago

To put that into perspective for other readers: I've been running for about 10 years also, but typically 2x a week (10k mid-week, 15~20k weekend), I have no real data on my heart rate from when I started, but at rest I'm now typically at 60bpm.

I measure almost daily due to medication and having a minor heart defect, and I have noticed that if I skip a week of running, it'll slowly go up, averaging at ~62bpm, but when I train for a (half) marathon I typically increase my distance a bit and try to train every other day (~3x/week) then my heart rate a rest goes down a bit to be consistently below 60bpm (58bpm avg).

40bpm is very low, for non-athletes this would be considered dangerously low, but I guess daily running at OPs distance would classify OP as an athlete. Also keep in mind that heart rate differs per person, some people just naturally have a low heartbeat.

There is this channel on YouTube named "Bruce Wilson", which I've got pushed onto my recommendation feed lately, and I've watched some of the videos:

This guy drives a Scania in the US, and it feels like he is more like a marketing stunt for Scania. He shows other truckers his one and they are all so surprised about the quality of this European truck, them getting the feeling that the US truck industry has been sleeping for decades in terms of evolution.

It should be easy for Volvo and Daimler Trucks to do the same, but I do not know why they don't do it.

> He shows other truckers his one and they are all so surprised about the quality of this European truck, them getting the feeling that the US truck industry has been sleeping for decades in terms of evolution.

As a European visiting US/Canada I once struck a conversation with a truck driver who had a really cool vintage semi, with lots of chrome and flare. I told him that I really liked the look of his truck, but that vintage trucks of that age would never be allowed on the road again in Europe, at least not for commercial jobs.

He then told me his truck was basically brand new...

Besides me making a fool of myself, I really grew an appreciation for the EU having rules about semis, especially in the noise department. Yeah, US domestic semi trucks are cool in their own way, but the constant noise of clutch fans, air brakes, 'jake' brakes, 'stack' exhaust with no of mufflers, etc. would drive me insane.

In (most of) Europe, all vehicles are subject to strict noise and emission rules, and many larger cities are now congestion zones which prohibits larger/older diesel powered vehicles from entering the city. Same for my city, where most trucks and busses are now electric. Since it happened gradually the change wasn't all that noticeable, that is until you go somewhere else and hear (and smell!) a diesel powered bus/semi drive by... We like to complain about all the 'stupid' government rules, but when you go to a place without those laws you really start to appreciate them, it truly feels like taking a step 'back' for the worse.

   "Contract is signed! No confidentiality, AMD has leadership that's capable of acting. Let's make this training run happen, we work in public on our Discord.

It still amazes me that George/Tinycorp somehow seems to get AMD on board every time, and being blissfully unaware that they are a very small player. See for example top comment here [0].

Don't get me wrong, I think it's impressive what he achieved so far, and I hope tiny can stay competitive in this market.

I recon you mean that the GIF is animated? I tried pasting this with the article URL in Whatsapp (web), but it did not render any animation for me.

Care to elaborate on why you posted this?
