_ph_··on Optimizing Beer Glass Shapes to Minimize Heat Transfer – New Results
Yeah, I got myself Stanley beer mugs and "glasses" and they are a game changer for keeping your beverages cold. This is extremely useful on hot days but even on not so hot days it is outright amazing how cold the beer stays. If you like your beer very cold there is nothing better.
_ph_··on Amazon reveals first color Kindle, new Kindle Scribe, and more
Though, the RM Pro has 229 ppi vs. the 300ppi for the scribe. So for black and white text, the scribe still has a small edge. But it would of course be cool, if the scribe eventually gets color at 300ppi.
_ph_··on Starship Flight 5: Launch and booster catch [video]
Sure, thats what they did with the JWST. But that ist complex and expensive. A custom Starship could be the cheapest way to get telescopes up to 9m mirror size into space as you can assemble everything on the ground and you don't need a separate housing.
_ph_··on Starship Flight 5: Launch and booster catch [video]
If anything, the last 2 flights have shown how good a decisions it was to go with steel. The thermal reserves seem to be really large. While not as bad as with the previous flight, there was still significant leakage of hot air between the starhip and the flap. But it didn't seem to cause significant damage, at least as far as for the landing. For complete reuse, they probably have to still improve that a bit.
_ph_··on Starship Flight 5: Launch and booster catch [video]
For things like that, they could build special versions of the star ship which remain in orbit as the housing. They would need no flaps, no tiles, just the 6 engines and the fuel tank. The body of the starship itself would be the telescopes tube.
_ph_··on Fukushima Reactor: TEPCO robot aims to extract nuclear fuel
The nuclear emissions seem to be optimistic in their absolute amounts - mining and producing nuclear fuel causes a lot of emissions. No one claimed it exceeds the one of fossil fuel power plants.

There has been a strong decline in coal usage in the last years, both because the CO2 prices have started to move the balance and also because the buildup of renewables has been accelerated again. And no, France hasn't been "filling the gap". Until very recently, Germany had been a constant net electricity exporter.

_ph_··on Fukushima Reactor: TEPCO robot aims to extract nuclear fuel
That is not correct. Yes, we are building more gas power plants. As peaker plants to pick up the residual load. That can in theory be the total net power requirement, which is why we need many of them. However, they are not running continuously. Already today, most gas power plants are idle most of the time. Gas usage by Germany is going on a steep decline as renewables are built up and especially as heating systems are converted to heat pumps.
_ph_··on Fukushima Reactor: TEPCO robot aims to extract nuclear fuel
Your argument would be valid if nuclear power would be the only option to prevent climate change. But there are other options: the various renewables, most importantly solar and wind. So it is not nuclear vs. climate change, but nuclear vs. solar/wind.
_ph_··on Fukushima Reactor: TEPCO robot aims to extract nuclear fuel
Whether the number for France is correct, is debatable. While I like the electricitymaps app, they are quite optimistic about nuclear power. But that isn't the point. The point is: Germany is strongly reducing the usage of coal. Yes, historically we have burned far too much coal, but that cannot be changed retroactively. What can and is being done is to replace coal as quickly as possible and that is happening.

Ironically there was a spike in coal usage in 2022, that was caused both by the war Russia started against Ukraine and even more so by France having to shut down too many nuclear reactors for repairs - German coal had to fill part of that gap.

_ph_··on Fukushima Reactor: TEPCO robot aims to extract nuclear fuel
Somewhere between 2-3x the electricity consumed right now (which is way down from the peak several years ago as efficiency increases, e.g. LEDs instead of light bulbs etc.). It would be crazy expensive to build nuclear reactors to produce so much electricity, with renewables it is still quite a task, but a much more manageable one.
_ph_··on Fukushima Reactor: TEPCO robot aims to extract nuclear fuel
Yes, Germany has a historic debt there. However, the transition is working and in 2024 Germany has used less coal than any year after 1960. Coal power usage is in a strong decline. The nuclear reactors have been more than replaced.
_ph_··on Eliminating Memory Safety Vulnerabilities at the Source
Oh sure, for the Linux kernel, Rust makes a lot of sense and one would try to keep the number of languages used minimal. But I was speaking about an abstract context. There are plenty of memory safe languages which could be used. But eventually, one has to decide for one.
_ph_··on Eliminating Memory Safety Vulnerabilities at the Source
That is the separation between abstract considerations and a given projects constraints. In a given project there might be few choices, but if you talk about fundamental phenomena, you have to reason about arbitrary projects. And of course, there are plenty of alternatives to Rust. Even limited to Android, there are several choices, even if they might be a smaller set.
_ph_··on Nintendo has filed a new 24GHz wireless device with the FCC
The nice thing about Nintendo is, they are one of those companies who are willing to try something entirely different and new. Sometimes they fail spectacularly, but often enough they have success and definitely have brought a lot of nice and cool stuff to gaming. It is quite exciting to hear that they have something entirely new in the pipeline.
_ph_··on Another police raid in Germany
There are quite a bit of differences here. The mail services transport physical goods, and the whole path can be tracked. Every letter or parcel is registered by the postal office where it was submitted to for transport. And usually there is quite some physical evidence with everything you do mail.
_ph_··on Another police raid in Germany
And it doesn't need to be a "really bad actor". I have been spammed by someone for years who clearly used a script to target an online service of mine. Always connecting from TOR, so banning an IP or a range wouldn't block that person.

This shows how easily TOR can be abused, even for small misdeeds.

_ph_··on Apple Watch Series 10
For me it is quite simple: if a watch has a seconds hand, I wand to be able to see it :) So I consider this change really an important part of "always on". I hope, they adjust most watch faces not to hide parts any more in idle state.
_ph_··on Apple Watch Series 10
I hope they add a hh:mm:ss watch face/option soon.
_ph_··on Apple Watch Series 10
Well, shaking the arm will do the trick. But I really look forward to have the seconds hand visible all the time. The always-on display was a huge step for the Apple watch and this enhancement completes it, as all hands keep visible all time. I hope, that affects all watch face elements which were hidden so far.
_ph_··on Synthetic diamonds are now purer, more beautiful, and cheaper than mined
I am pretty sure, diamonds would make awful eyeglasses. While their index of refraction is high, which makes glasses thin, their chromatic dispersion is high. That is the very thing which makes their glitter so colorful. For good optical systems you want to try to reduce the dispersion, to 0, if possible.

Another story is the scratch-resistance. For that it would be sufficient to coat the surface of the lens with a thin layer of diamond. Which is done in several applications.

_ph_··on Apple Watch Series 10
As I have big wrists and my eyes aren't getting better, I like a larger screen a lot. But for me, the most important update might be, that the screen now updates every second instead of every minute in the "inactive" mode. I do use the seconds display of any watch a lot when timing short things, especially when cooking. Whenever I want to watch the seconds, with my current watch I have to keep shaking my wrist to keep it active. Having a seconds display all the time is the big step to make it a real watch. I hope they also add a digital watch face with seconds display.

I would have like a bit better run time - as the CPU is getting more efficient, I hope Apple is downplaying any enhancements. With my 7 series Apple watch I do still get 24 hours of run time (wearing it at night) after 3 years, so it is just sufficient. But a bit more would add safety margin.

A future Ultra 3 would be tempting with a longer run time and especially the red "night vision" watch face. I would so much like to have it on the plain Apple watch - clearly that is an artificial limitation.

_ph_··on iPhone 16 Pro and iPhone 16 Pro Max
May be not an earth-shattering update vs. the 15, but overall a lot of improvements. Probably more so for the plain iPhone 16, as it gets the A18 SOC, the Pro seems to have mainly one CPU core more.

As I am on an iPhone 13 Pro Max, still in total absolutely a worthy upgrade for me. I certainly look forward to it. The advantages vs the 15 I can see so far:

- updated SOC, somewhat faster, but up to 30% more power-efficient which turns into

- larger battery life. Thats something everyone will welcome, I guess.

- better camera: 48mp wide angle, 120mm tele lens, 4k 120 Hz.

- a bit larger screen, too bad they at least didn't name any other screen enhancements

- the shutter button. A ton of functionality built into one single button. Pressure/touch sensitivity, haptical feedback. That should greatly improve its usage as a camera.

- all the AI stuff. We need to wait how it delivers, when it arrives (especially, if you are outside the US), but that could get interesting when it delivers.

While there wasn't any big surprise or outstanding change, for a year over year update a lot of things and definitely very nice for everyone with an older phone than the 15.

_ph_··on iPhone 16 Pro and iPhone 16 Pro Max
They said that the iPhone can record video directly to external storage, so you would need the faster USB speed for that. Quite a nice feature for productions which use the iPhone for professional video.
_ph_··on iPhone 16 Pro and iPhone 16 Pro Max
The German website doesn't list it either, but lets hope that is just an issue with the web site.

Edit: if you go to the comparison page, it lists the blood oxygene app for the 10 and the Ultra 2, so great :)

_ph_··on iPhone 16 Pro and iPhone 16 Pro Max
Scrolling is quite much more plesant at 120 Hz.

_ph_··on iPhone 16 Pro and iPhone 16 Pro Max
Wow, if they removed the blood oxygen measurement, I will keep my S7 Apple watch. I had planned an upgrade.
_ph_··on ReMarkable Paper Pro
Which device would work better than the remarkable for its intended purpose of note taking?
_ph_··on ReMarkable Paper Pro
You can ssh into the remarkable and copy files via scp.
_ph_··on ReMarkable Paper Pro
A highly interesting release. I love my remarkable2 as a note-taking device. I also own a Kindle and an iPad, so reading books or running apps isn't my requirement. I only need something to take notes and that the remarkable does very well. Funny though, that color wasn't the most missing feature. But it is very intriguing that it seems to have the first full-resolution color displays, with the color being part of the eInk pixels. From a practical side, the additional screen space probably is the biggest feature to me. I would hope for some more software improvements, like a few more drawing tools, especially as the colors make that even more appealing. Also, I would like to have an image slide show and of course an official option to customize the sleeping/off display images.
