wolfd··on A Chinese Satellite Just Grappled Another and Pulled It Out of Orbit
The technology for moving dead satellites is long overdue. Sure, it has military implications, but it's a heck of a lot more responsible than anti-satellite missiles.
wolfd··on NASA Says Webb’s Excess Fuel Likely to Extend Its Lifetime Expectations
I think that the other commenter was referring to the relative complexity in JWST's unfolding/deployment. It might be possible to deploy something from Starship that doesn't need to be packed as tightly (and save on engineering costs there) and still get around the same performance.

A complicated sunshield deployment seems somewhat inevitable, personally, but I'd be happy to be proven wrong there.

wolfd··on Ambiguous PNG Packer: Craft PNG files that appear different in Apple software
The worse one is opening another script tag right after closing the first. XSS dream.
wolfd··on Username ending with MIME type format is not allowed
They're pretty much interchangable. Video frameworks like gstreamer just give you qtdemux to parse .mov, .mp4, and even .m4a or .m4v (which are just MP4s with different file extensions).
wolfd··on Steam Top 50 Games: Over 70% now work on Linux
Fun fact: that watermark is created by explorer.exe, and if you're not running explorer.exe it doesn't show up. I had a box that went through one too many hardware changes and Windows decided that it wasn't on the same machine. I didn't bother contacting support for months because I had set the Windows "shell" to be steam.exe in Big Picture mode, and so I rarely got bothered by it.
wolfd··on A Polynomial Time Algorithm for 3SAT (P=NP?!)
Also from right before that paragraph in the introduction is this strange argument:

> Also there are famous scientists agree that NP=P. Hilbert, a great mathematician of the twentieth century, has afamous saying: we must know; we will know. It can be seen that Hilbert essentially agreed that NP equals P. Many mathematical problems in human history, including Hilbert's famous 23 mathematical problems, are constantly beingsolved. Isn't it a confirmation that NP equals P?

wolfd··on The top-ranking HTML editor on Google is an SEO scam
Everyone starts somewhere.
wolfd··on A Model of the Cosmos in the Ancient Greek Antikythera Mechanism
It's tough to make gears with that many teeth, especially if you want them to mesh with smaller gears.

Also, meshing against a 1-tooth gear is problematic, so you would need to probably increase that to >4 teeth to have it work. Then your bigger gear needs to have >4x the teeth to get the desired ratio.

They briefly mention the statistic in the last paragraph.

wolfd··on If you want peace, study war
Additional recommendation: The Fog of War, the McNamara interview documentary. Absolutely fascinating look into the mind of the secretary of defense at the time.
wolfd··on Non-Posix File Systems
Along those lines, one thing that has bothered me is that we can't prepend files, even with modern SSDs with fancy controllers. Those controllers are jumbling the contents of a continuous disk onto different chips, and different sections on those chips.

For things like MP4 metadata that usually need to be near the beginning of a file for the MP4 to be considered streamable, it can be quite cumbersome. Being unable to expand a file from the beginning means that fancy MP4 writers write a bunch of blank space (perhaps guessing the necessary size of the metadata portion), then after the stream data is written, go back and hope that they allocated enough blank space to fit the metadata within. If the writer was wrong, either it has to put the metadata at the end of the file (preventing streaming), or has to rewrite the entire file with a bigger buffer.

Perhaps it is a wish that requires too many layers to be changed to be possible, but I like to dream.

wolfd··on Google offers free fabbing for 130nm open-source chips
Approximately zero. They have nothing to gain from doing so, and everything to lose. It isn't a website we're talking about, adding that kind of complexity to a chip would be highly obvious to the people who integrate it, who aren't from Google.
wolfd··on U.S. Watched George Floyd Protests in 15 Cities Using Aerial Surveillance
Not wanting A doesn't mean that someone supports B.
wolfd··on MIT Ends Elsevier Negotiations
The current losses in public education will be felt on the decades timescale. I think the perspective here on HN is probably shifted due to the tech demographic, where VC and ads have provided a buffer.

Systems have inertia, stuff continues working until it hits a wall. The unemployment systems written in COBOL kept churning until now, for example.

I think the cuts in jobs might give the impression that "we never needed them in the first place," and maybe that's true in some cases, but it's hard to distinguish right now from the effects that take years to surface.

wolfd··on Team Fortress 2 source code has leaked
I doubt it, due to how the leak is purportedly from 2017/2018 code, and according to the tweet from SteamDB is the version that is included to Source engine licensees.

The original hl2 code leak was a fan from Germany that hacked into Valve's network and stole a version. https://arstechnica.com/gaming/2016/06/what-drove-one-half-l...

There are YouTube channels like VNN that rely on Valve leaks, but most of it seems like running `strings` on their update files. He does claim to have some inside sources, but they mostly seem to provide social commentary on Valve internal politics.

wolfd··on Pcileech WebRadar – browser based radar cheat for CS:GO
Competitive gamers care way too much about latency to use cloud gaming services for tournaments. Some Counter-strike players still use CRT monitors due to the latency advantage over LCD. I think that you won't see much adoption in competitive gaming, where every millisecond counts.
wolfd··on Unmasking Northrop Grumman's XRQ-72A
That would be true if they weren't using fuel to power it, which they are. Part of the article shows the alternator they were possibly going to use.
wolfd··on NBA suspends season over the coronavirus after player tests positive
Old people in nursing homes don't get out much, and yet they're the ones that are dying. The fact is that the virus spreads because people don't always die from it, and so they go around spreading it to people who will. Most people probably won't know that they have it until they've spread it to 3 more people.

Your strategy will probably keep you alive, but the same is not guaranteed for many millions of people that are old or with immune system complications.

wolfd··on Linus Torvalds: Linux Scheduler Not to Blame for Google Stadia Port Issues
It's hard to beat local compute for latency.
wolfd··on One million lines of code ought to be enough for anybody
I still don't understand why anyone would want this. It seems pretty hostile to the users of Python without any real benefit. Maybe the benefit is the people who are pushing for the change get to smugly know that people won't do horrible things with the language. Maybe I don't get it, but... why?
wolfd··on California oceans rising in acidity at alarming rate, study finds
While some headlines may be overly aggressive, many (anecdotally) of the very serious consequences of climate change are predicted to happen on the order of 50/100 years from now.

There are a couple reasons this sucks: - some people seem to not care about that far in the future - people seem to be pretty bad at detecting change in their environment over longer time scales

A memorable example of the second one: https://www.npr.org/sections/krulwich/2014/02/05/257046530/b...

wolfd··on The Tech of Pixar: Piper (2017)
Any idea why they might have stopped?
wolfd··on Military Has Been Researching "Anti-Gravity" For Nearly 70 Years
It's still worth a call-out. The other line in the article that always gets me is "Sometimes, attendees [of the Gravity Research Foundation] sat in chairs with their feet higher than their heads, to counterbalance gravity."

It feels like absurd lore in Fallout, but probably actually happened.

wolfd··on Gitlab: don't discuss politics at work
If someone touched me in any physical way at work I'd say it would be unwanted. It's pretty reasonable to not want other people to touch you, no matter the specific "kind" of touch it is.
wolfd··on CamScanner, a malicious Android app with more than 100M downloads in Google Play
This seems like a pretty big oversight on Gmail's part.
wolfd··on Standard JS: npm install funding
What do you mean? Is there some announcement/feature I was unaware of?
wolfd··on Standard JS: npm install funding
While a lot of commits, the actual content shows very few functional changes. Actually, most of the changes are indeed ads for companies that use the package.
wolfd··on Disney Announces $12.99 Bundle for Disney+, Hulu, and ESPN+
You should probably provide a link with that. I don't know if it's fair to say that everyone here is going to pay for this, or even was considering it. Perhaps a less blaming tone might help your case?
wolfd··on Space Engine
SpaceEngine let's you zoom through _galaxies_ like that old windows screensaver was for stars. I've always sorta understood that the universe was "big", but it never clicked how infinite it really is until I zipped through SpaceEngine for an hour.

That said, Elite: Dangerous is pretty awesome. It helps ground how far away everything is. Even with the game's FTL travel, the fact that it takes actual weeks to reach Sagattarius A* boggles the mind.

wolfd··on Stadia Founder's Edition
Google bought YouTube when it already dominated the video sharing market. Stadia might not dominate the gaming market in a couple years. Google likes to kill products that don't consume all, at least, that's what it looks like to me.
