Escapado··on Apple unveils all-new MacBook Air, supercharged by the new M2 chip
I am torn... One one hand I think I want this as an upgrade to my 2016 MBP, on the other hand the 14" Pro has a 120hz display. And although I mostly code on it on the go I got so used to 144hz on my desktop monitor that I kinda feel like an upgrade should include that too. I get that this would totally canibalize their more expensive models but one can dream.
Escapado··on Apple Unveils M2
They were so careful not to compare it to the M1 Pro!
Escapado··on Tesla’s ‘phantom braking’ problem is getting worse
I kind of agree, however at least from my experience in Germany keeping at least the minimum legal distance is an exception rather than the norm. It kinda makes me mad and I wish it was mandatory for all cars to have sensors which would either not allow you to get closer given a certain speed to be in line with the regulations or at least make a really annoying sound so that you simply wouldn't want to. I would bet this would save so many lives.
Escapado··on Show HN: I hacked my son’s Duplo train to go faster using my voice
This is so cool and so cute at the same time! Love it! Maybe an alt mode could adjust speed according to the frequency of making a "tschk" sound. :)
Escapado··on Show HN: Monolith – A stylish and functional computer frame
Best of luck for the campaign. Judging by how much dust I regularly have to clean from my case meshes (we have a dog and clothes are often hanging to dry in my office) I would probably never buy an open case but they look kinda neat. Lookwise I would prefer the xproto but it's always nice to see alternatives. :)
Escapado··on 9-Euro-Ticket
You are right, however if it would have been made free and kept free indefinitely this would have been a one-time cost.
Escapado··on 9-Euro-Ticket
When I was still in school about a decade ago an exchange student from the US was flabbergasted at our gas prices when she found out that the signs at the gas station would display the prices in €/l and not €/gallon. Quick googling shows that €/$ was 1.45 around that time and gas prices were around 1.42€/l which would be a little over 2.06$/l or 7.79$/gallon. At the time the gas prices in the US was 2.79$/gallon.
Escapado··on 9-Euro-Ticket
I would argue making it free and keeping it free would have been a cool move. - Less/no expensive accounting - Less/no personnel for checking tickets - Less/no personnel for prosecuting people who don't have tickets - Less/no ticket vending machines (and all the maintenance that comes with it) - Less traffic on the roads since you can't beat "free" and hence less emissions (at least in hamburg trains operate on green energy) and less wear on the roads (might be offset by the wear on trains and busses) - Fully non-discriminant with respect to income

I have no idea if that would work for inter-city transport but for inner-city transport the HVV for example (the public transportation network responsible for hamburg and surrounding areas) sells 30 million tickets a year and I wonder how much it truly costs them to do that with all the relevant factors mentioned above.

Escapado··on Average home prices in New Zealand reaches 8.8 times average household income
When I talked to my parents they told me most of their peers would pay off their mortgage within 20 years but maybe times changed, I don't know the data on that. I am 30 now and I have trouble imagining being in debt for a time equivalent to my entire lifetime so far - just to live in a house. 15 years sounds so much more bearable emotionally but it's probably never gonna happen. You are obviously right about 2042 payment levels probably being different but that also hinges on inflation being positive - but I would agree that that's more probable than deflation.
Escapado··on Average home prices in New Zealand reaches 8.8 times average household income
It's pretty much the same for anything around the city of hamburg in the north and most of the time it's less about the houses and more about the land they sit on. Building got more expensive but land even more so. 1.000 EUR/m² of land for adjacent cities are becoming the norm.

Most of my friends graduated from university with either a bachelor or a masters degree and only those who stand to inherit a sizable sum of money or their parents home are going to have houses. A 50k salary simply won't cut it. Most have given up on the dream entirely since 30+ years of debt is not something they can justify.

As a quick back of the envelop calculation:

Let's say you had a household income of 86k for two people (43k+43k) which translates to about 4550 EUR per month after taxes, health insurance and pension fund. Their cost of living on average (not including rent) in the hamburg area would be somewhere around the 1900 EUR mark, leaving about 2650 EUR per month. Since people need to save at least a little money, or go on vacation once in a while or repair their car or maybe they have kids it's probably generous to assume they could use 2000 EUR per month to pay off a house.

Let's say you'd get a house for 600k all inclusive and you had to take on 500k of debt. With a current interest of about 2.76% fixed for 20 years and paying off 2000 EUR per month, then after 20 years you'd still be at about 224k of debt and you'd have paid 203k in interest. Assuming the same interest thereafter it would take a total of 30 years and 10 months to pay the house off entirely. During that time larger repairs or renovations are likely needed which would most likely forbid to pay off more than 2000 EUR per month.

Now one could argue that people could find places for half as much in rural areas but then again, lots of professions won't find any jobs there and those that do often get paid way less. Somehow the situation saddens me. My parents bought a semi-detached house 20 years ago for 200k (which would be 264k today adjusting for inflation). Two identical semis in the same street got sold last year, each for more than 500k, so pretty much double the inflation adjusted prices albeit being 20 years older houses now.

Escapado··on 7GUIs
To add to the list: Coming from the web and being used to having a ton of control how every thing looks I found that customizing elements sometimes have surprising limitations in SwiftUI. Also be wary of trying anything UX wise which is non-conformant with the official spec.

Also xcode in general is such a bizarre IDE compared to the IDEA products or even VSCode which I felt was limiting me severely, even after making quite some effort to adjust and learn shortcuts. I also found that the screen/component preview was just so inconsistent, performance hungry and slow that I stopped using it pretty quickly. I want to like SwiftUI but it feels too rough around the edges for me so I guess I'll check back in a year.

I tried flutter after and it was SO much less painful, more/easier customizable and tooling felt heaps better.

Escapado··on Overengineered Japanese Mechanical Pencils [video]
This is crazy cool! I wonder how these miniscule and thin lead sleeves are produced and how they manage to stay within tolerance and even get a rounded edge.
Escapado··on Faster Python calculations with Numba
Quite a few years ago I worked on a particle in cell simulation software during my bachelor thesis[0]. We used numba to accelerate the code and most importantly write GPU kernels for the heavy parts. I remember spending hours optimising my code to eek out the most performance possible (which eventually meant using atomics and manually unrolling many loops because somehow this was giving us the best performance) but honestly I was really happy that I didn't need to write cuda kernels in C and generally it was pretty easy to work with. I remember back then the documentation was sometimes a little rough around the edges but the numba team was incredibly helpful and responsive. Overall I had a great time.

Escapado··on Deno in 2021
About 3 months ago I got my feet wet and fiddled around with it for a bit. Eventually I used it to deploy(using deno deploy) a small script which would forward calls to an unofficial API of some App. It turned out chrome would not let me set a Cookie header (which the API required) due to some security policy in my axios calls so my script would proxy the request and inject it when calling the API. I was pretty amazed by how easy the whole process was. I can see myself using it more often for side projects and even recommending it at work (If I get the enterprise java crowd to try something new).
Escapado··on Three Steps to the Future
Growing up with a specific, media influenced vision of VR(Ghost in the shell, .hack, sword art online) where lots of of the current technical challenges to create something truly immersive are solved, I really want VR to succeed. I got to try the original Oculus Rift and later Quest and I would argue that visually we are maybe 5 or so years away from a pretty decent experience (like 4k by 4k per eye with decent latency, 120hz+, no screen door and maybe even proper foveated rendering). Sound-wise I don't even think there is much missing. Form-factor/comfort-wise I also believe that we are not far off. And experiences which make use of "just" that are ok or fun even.

IMHO however, movement and tactile feedback are still lacking so far behind that I don't even know if they can be solved in a non-invasive, average user friendly manner. I mean sure, you can strap yourself to a treadmill contraption and use controllers or gloves to track your hands and maybe even wear some suit which vibrates here and there. But you won't feel real collisions, let alone texture, realistic force and acceleration. And somehow when I tried VR I felt like this was missing so much that it limits my enjoyment big time.

Escapado··on Ask HN: Do you tell your salary to people/family/friends outside your industry?
I'll happily talk about it with everyone who'd like to know. Also I firmly believe I am overpaid (as a freelance software engineer in germany) compared to people in other fields such as for example social workers or most hospital staff and even compared to my employed peers. I find it difficult to express that without it sounding like a brag. This year, so far I have made about 120k Euros (in profit before taxes - will be about 140k by the end of the year) from one full time project in which they couldn't staff enough developers. The FTE in that same project make between 75k and 85k. Talking about it helps me put things into perspective and has led to a few of my colleagues reconsider their employment. Now, having trippled my income by becoming a freelancer has actually not changed my lifestyle at all and I save up about 75-80% of my money to buy a house someday. I have not been met with open toxicity about it yet and I don't expect my current streak of luck to last forever.
Escapado··on Pop OS – System76
I switched from xubuntu to pop about two months ago and generally have a good time using it. I like the tiling wm and had to configure very little and except for the crappy WiFi stick everything worked out of the box.

Being the idiot that I am I thought I wouldn't need a swap file and now everytime my ram is full my system freezes entirely.

Escapado··on CO2 battery could make wind and solar dispatchable at a lower price
This one I presume:

----------------------------------------------------------------

Dear battery technology claimant,

Thank you for your submission of proposed new revolutionary battery technology. Your new technology claims to be superior to existing lithium-ion technology and is just around the corner from taking over the world. Unfortunately your technology will likely fail, because:

[ ] it is impractical to manufacture at scale.

[ ] it will be too expensive for users.

[ ] it suffers from too few recharge cycles.

[ ] it is incapable of delivering current at sufficient levels.

[ ] it lacks thermal stability at low or high temperatures.

[ ] it lacks the energy density to make it sufficiently portable.

[ ] it has too short of a lifetime.

[ ] its charge rate is too slow.

[ ] its materials are too toxic.

[ ] it is too likely to catch fire or explode.

[ ] it is too minimal of a step forward for anybody to care.

[ ] this was already done 20 years ago and didn't work then.

[ ] by this time it ships li-ion advances will match it.

[ ] your claims are lies.

Escapado··on TinyPICO – tiny fully-featured ESP32 board
I've always wanted to try getting into iot and see if I can set up a small network of sensors each attached to one of these tiny low power boards and see if I could operate them using some sort of energy harvesting so they'd be mostly maintenance free.

If anyone more knowledgeable would like to share their insights or favourite ressources on the matter I'd be really interested.

Escapado··on AMD 3D Stacks SRAM Bumplessly
Interesting technology. Is everyone using it? And if not (I recall tsv being used a lot) then why? The wiki entry paints a very positive picture here.
Escapado··on Making $100k as an Employee versus Being Self-Employed
Yep, that's correct.

And no they don't most of the time. Investigations about this are rare apparently and also only working for one customer in that capacity at a time is not really an indication of pseudo self-employment or tax fraud.

If the company dictates you your work hours and you suddenly appear in organisational diagrams as if you were employed and you were part of all company meetings and a couple of other things in the same vain then that would be indicative of pseudo self-employment. It's basically mostly about whether you are bound by instructions or not. This is however checked rarely (usually it would need to be initiated by one of the participating parties and we do not want that) and also hard to do rigorously. The laws around that are mainly to protect people from earning too little and being subject to paying all their social insurances/taxes by themselves and not getting any vacation days. For higher paying jobs this is not much of a threat since being paid higher than an average FTE would also count as indicative for being self-employed. Same goes with working from wherever I want (yay homeoffice).

If pseudo-self employment were ascertained during an audit my customer would need to retroactively pay the social insurances for the months I worked for him and if he were to employ me further he could deduct that from my income of the following months but only for the last three or four months. I think there is a chance under very specific circumstances that the customer could try to demand that I would have to pay the difference between what a normal FTE would be paid compared to what I was paid but it's not yet clear whether that is actually lawful and I think it only applies if both parties were not entirely clear that the business relation ship is based on the premise of freelancing.

All in all I am not very concerned that it will actually ever be a real problem. I have talked to at least two dozen freelancers doing what I do. Sometimes for over a decade and never once have they been questioned in their status in any way.

Escapado··on Making $100k as an Employee versus Being Self-Employed
Over the last 8 months I had 158 billable hours on average per month. I get about one to four calls per month offering projects (full time, 3-6+ months) in my city or fully remote at that rate without doing any active marketing. I just have a Xing profile and I am listed at a couple of job adviser agencies such as Gulp or Hays. Also I only do full time projects (for me they have been by far the majority anyway).

So either it's webdev specific right now or I am just incredibly lucky but even as my current project is near its end I have about 3 options to chose from to continue elsewhere seamlessly after. Other freelancers I met in the field have reported similar situations but that's just anecdotal evidence. Would you have a reference of where that 50% unpaid time comes from?

Escapado··on Making $100k as an Employee versus Being Self-Employed
I'd like to offer a german perspective on this. I've been a freelancer (webdev) for about 1.5 years now (about 3 years of experience) and this is how that calculation would look here:

Employed at 100k Euro, no kids, not married:

- 27.406 Euro income tax

- 1.243 Euro solidarity tax

- 7.923 Euro pension fund

- 1.022 Euro unemployment insurance

- 1.030 Euro statutory nursing care insurance

- 4.440 Euro health insurance

= 56.932 Euros left over.

Health care can be made a bit cheaper with a private insurance company but this is the ballpark most people would be in. All the listed taxes and insurances are mandatory.

Freelance with 100k Euro, no kids, not married:

- 22.290 Euro income tax

- 1.225 Euro solidarity tax

- 10.594 Euro health insurance

- 15.840 Euro pension fund

= 51.310 Euro

However: Paying into the pension fund is not mandatory as a freelancer and you can also choose how much to pay and health insurance can be made cheaper here as well. Health insurance and pension fund will be deducted from your taxable income. Also as others have mentioned you can suddenly deduct a lot of things (phone bills, parts of your electricity bill, buying a new laptop etc.).

The main kicker here however is this: I work as a freelance webdev and so far I have managed to make about 80 Euros/hour which given my current workload will result in about 130k Euros of income this year. I have yet to get an offer from any company willing to pay more than 100k.

Escapado··on FlutterFlow: Low-code Flutter apps
To be honest this is the best selling point in my opinion.

It's a great tool for MVP scenarios and especially in business contexts that price tag is entire negligible compared to the hourly rate of most engineers! So a single hour saved will already make up for it.

Escapado··on Quantum Computer Datasheet [pdf]
I am sometimes ashamed about my choice really since it seems like taking the easy route instead of pursuing something more meaningful. But almost 4 times the net income and a lot less anxiety and pressure are hella compelling when you want to start a family some day. I even saved up money for pursuing a PhD without feeling like I have to compromise financially all the time but remembering the stress academia caused me I am not sure anymore.
Escapado··on Quantum Computer Datasheet [pdf]
I am a little rusty on this but rotations around the z axis on a Bloch sphere can be implemented by either detuning the qubit frequency with respect to the drive field(real z gate) or as a composition of X and Y gates when introducing a phase offset in the field with respect to those gates(virtual z), which is why it takes no time since it's implicitly part of the other operations.
Escapado··on Quantum Computer Datasheet [pdf]
I am a webdev nowadays but a physicist by trade and wrote my master thesis on quantum circuit synthesis using machine learning about 2.5 years ago. Whenever I see quantum computing news come up here I kind of want to get back into the field and preferably not purely in academia. However I am also not willing to relocate so it will probably remain a pipe dream. But I digress, I am happy to see google continuing their investment in the field and that a lot of cool research will come of it.
Escapado··on AMA: Ivan Kutskir, creator of Photopea
Thanks for your perspective! I had no idea the stock compensation was THAT high. Sheesh I might want to reconsider my current situation!

Btw, I should probably not post this but we share the exact same name and work in the same field. :D

Escapado··on AMA: Ivan Kutskir, creator of Photopea
I mean even in germany it's not easy. The average salary of a SE here is about 65k before taxes. Most senior engineers I met make about 80-85k before taxes (~50k after taxes) (I am located in hamburg). Even for well booked freelancers about 1 in 10 people make more than 200k a year (140k being the average which results in about 72k profit after taxes).

I just had a quick look at google, netflix, twitter and facebook and they don't even offer any SE positions here. Amazon has some in Berlin but they pay around the same salary as stated above.

Escapado··on "World's highest-capacity" solid-state battery developed in Japan
This made me chuckle. Is there a table anywhere with a lot of promising contenders as columns and those criteria as rows (or that transposed)?
