HeavenFox··on North Korean fake job interview led to $6.3B Binance heist
I do know people who no longer have a personal computer, and use exclusively their work-issued computer. I wonder how common that is.
HeavenFox··on Claude Code regularly sends each background agent’s transcript to its model
If they are literally sending the entire transcript and asking for a summary, wouldn't almost all of the tokens be cache hit, and therefore fairly cheap?
HeavenFox··on Zuckerberg's Meta Takes Down No Kings Instagram During Protest Day
Look, as much as we hate Meta... doesn't Hanlon's razor apply here - "never attribute to malice that which is adequately explained by stupidity"? Could it be that the account triggered some automated system?
HeavenFox··on New Apple TV 4K
Of all the major tech companies around the world, Apple has the most incentive to actually deliver privacy, and has the best track record.
HeavenFox··on Why isn't the industry freaking out about DeepSeek 4.1 Flash?
To be fair even OpenAI's and, to a lesser extent, Anthropic's models do that sometimes
HeavenFox··on Show HN: AstroHelm – Use your phone camera to aim a telescope or telephoto lens
Yes, the pointing shown in the app will always be correct, just the object will move out of the field of view. You need to manually track the object using an equatorial mount, or use a clock drive or similar.

The distance doesn't matter, since the stars are almost infinitely far away, so there's no parallax. You do need to correct for the angle though. We support daytime alignment using, say, a distant treetop, or at night align on the object you are observing.

We have a prototype polar alignment feature in the works! The benefit of plate solving is you can actually do a two-point polar alignment: just take two pictures with different RA, and we will know where the axis is. Taking more pictures would improve accuracy.
HeavenFox··on Show HN: AstroHelm – Use your phone camera to aim a telescope or telephoto lens
So the reason that line of text is there is we designed AstroHelm to be mounted directly on the telescope facing the sky. We don't want our users to go to Amazon and search for "telescope smartphone mount", get an eyepiece adapter, and found that it doesn't work :)

As for why we don't support adding optics between the phone and the sky, there are a few reasons. The accuracy from phone's camera lens is good enough, and we don't want to introduce complexity. The plate solving algorithm also benefits heavily from knowing the field of view, which you get from phone's built in camera but need user input for custom optics. Finally, supporting smaller field of view means shipping a much larger star database which most users won't use, so it's just a waste of storage and bandwidth. Not to mention blind solving a small FoV would be very slow and not work interactively.

For alignment, we support two alignment methods. You can align it like a finderscope, i.e. aim your telescope at a distant treetop and drag the crosshair over it. Once you begin observing, you can also sync to the object, which should give you better accuracy.

We launched Android recently and was using this opportunity to experiment with pricing and packaging a little bit!
HeavenFox··on Show HN: AstroHelm – Use your phone camera to aim a telescope or telephoto lens
Since the plate solving happens periodically, the sky drift will quickly be corrected!
HeavenFox··on Show HN: AstroHelm – Use your phone camera to aim a telescope or telephoto lens
It should. I have users reporting good experience with iPhone XS. It is heavily dependent on your local light pollution levels though.

They do! The "night mode" in camera apps all utilize gimbals
HeavenFox··on On social reality in China
That is the "mentality shift can take generations" part.

Those ladies may be part of the elite now. But remember their parents or grandparents went through the Great Chinese Famine where an estimated 15-60 million people died.

HeavenFox··on On social reality in China
This is likely because as the author admits, their interaction with everyday Chinese is mainly through the Internet and cultural products, which has a significant bias.

Chinese government actively shapes the online discourse, so the messaging is already filtered. To make it worse, it meant people found out that the easiest way to silence your opponent is to brand them as anti-China, so you see a lot of pro-China virtue signaling. Finally, people also realized patriotism is lucrative.

HeavenFox··on On social reality in China
I am Chinese living in America.

All the authors observations ring true, and they all stem from one simple fact: China was a very poor country just forty years ago, and even today is only a middle income country.

The uncomfortable truth is a lot of the things westerners take for granted are, in fact, luxuries. Arts and creativity is a luxury. Freedom to pursue passion is a luxury. Compassion is a luxury. Self-esteem is a luxury. If you barely have enough food to feed your family, as a significant number of Chinese people were in the 60s and 70s, you cannot afford any of these.

China has grown richer at a remarkable rate, but the mentality shift can take generations.

HeavenFox··on The AI Race Just Got Awkward
The post makes an assumption that US labs did not already possess similar optimization. It's also very possible that they did, but are simply not telling anyone in order to maintain obscene margins on cached read, similar to AWS' absurd pricing on bandwidth.
HeavenFox··on Dots: Always-on agents
What a terrible marketing page. I read it a few times and still have zero idea what this thing is.
HeavenFox··on I added a non-wi-fi Mitsubishi AC to Home Assistant
FYI this kind of thermostat is actually better. American style thermostat put your HVAC system in either on or off state (basically PWM), whereas this kind of communicating thermostat can tell the system what the temperature is, so they adjust power accordingly. I do wish they have standardized protocol though.
HeavenFox··on A misalignment of AI in mathematics
Agreed. The problem is not with AI per se, but with the reward mechanism in academia in general.
HeavenFox··on AnkiDroid: Google Play no longer allowing Open Collective donation link
I have apps published to both the Play Store and App Store, and I agree. Despite the stereotype, Apple is much nicer to deal with. If you work within the Google ecosystem, you enjoy none of the benefits of the supposedly open Android system, but need to deal with more bureaucracy, more limitations, and worse support.
HeavenFox··on U.S. State Department pauses immigrant visa applications
Based on my understanding of Australian PR, what you are renewing is not your visa but the travel facility.

For non-PR, I don't think Australia distinguishes visa and status like US (i.e. you can't have valid status while your visa expired)

HeavenFox··on U.S. State Department pauses immigrant visa applications
Is it? If I understand it correctly, in Japan, if you have a valid residence card, you can use that to enter the country. That is not true for the US (if you consider I-94 the US equivalent of residence card)
HeavenFox··on Startup Anti-Patterns
well... no, splitting a monolith once it has grown past the point where services make sense is incredibly difficult. My last employer spent a couple of years doing it and ultimately gave up. There is just way too much interdependency to split it up cleanly.

So the key here is good engineering leadership to recognize when that point arrives, and push the company to start the transition.

And indeed, microservices solve a organization problem not an engineering problem. When I taught the architecture to new hires, I always say: a service is the largest piece of system that stays together in a reorg :)

HeavenFox··on U.S. State Department pauses immigrant visa applications
You are talking about change (or extension) of status, not visa.

US is unique in that the visa sticker and your right to remain in the country (status) are two different things. The only purpose of the visa sticker is to allow you to travel to a U.S. port of entry, where you apply for admission, and therefore legal status. You can have legal status in the U.S. while the visa sticker has expired, and your status can be changed or extended domestically. However unless you have a valid sticker you cannot leave and return.

HeavenFox··on iCloud+ Hide My Email addresses will remain on icloud.com
Hostage may be a bad analogy. More like a game of chicken. Imagine you are a regular @icloud.com email user. Apple is basically saying "I dare you to block all @icloud.com email and lose all these customers"
HeavenFox··on One corner of China’s internet is insisting that the Tang Dynasty never existed
Note the reason of this conspiracy: the founder of Tang dynasty is not of pure Han Chinese ethnicity. In the grand scheme, this is just part of the rise of Han nationalism in recent years, which had its roots in the nationalism rhetorics adopted by the Chinese state under Xi.

I'm sure you can see the parallels of this in the United States and Europe.

HeavenFox··on iCloud+ Hide My Email addresses will remain on icloud.com
Case in point: many websites block all VPN except iCloud Private Relay. Thank you Apple!
HeavenFox··on Universal health coverage could save $1T and 114k lives a year: study
So basically as long as someone is alive in Switzerland they need to pay an insurance company $500/mo?
HeavenFox··on App Store Rejection of the Week: Dark Hours
This is likely an outlier. I submitted a new astronomy app (even with “Astro” in the name!) just a few months ago with no problem.
