I am getting at providing an accurate CGI representation of a moving solar system, according to the scientists...you know, real "sciency," based on Newton/Kepler/Einstein math...

I don’t know if that exists

Of course it does. Take any CGI model of a stationary solar system, set it running on your computer screen, then get up and walk past the screen. The screen (and hence the model) is now moving relative to you.

Suggestions & Concerns / Re: Library not on https
« on: March 10, 2020, 12:16:55 PM »
I know this website isn't malicious. Do the people who just happen upon it, know that? Does google believe that? Its just about trust. Something tfes.org usually gets right.

HTTPS makes no difference if the website is malicious. Indeed, if you don't trust the website owner, then HTTPS is entirely useless for security. What's the difference between fetching content from someone you know you don't trust, and a third party you don't trust?

HTTPS is only useful for protection against malicious third parties, as well as for a small boost to user privacy. If the party you want to talk to is malicious, all bets are off.

We may also find that google looks a little more kindly on some of our resource pages when it comes to serving search results.

Yes, Google is well known for bullying smaller websites into falling in line with their hype of the month.

The library hosts only public files, so there is limited value in having TLS there. Your browser is a hypochondriac.

The reason why our normal X.509 certificate does not apply to the library is that the library is hosted on S3, separately from our other services.

That said, there is no harm in having it. I'll look into it sometime as a low priority.

Which suggests the link to the store really should be from the forum menu too. Its forum users who will make purchases.

The forum menu is quite cluttered as it is. If we're going to add stuff to it, I'd like to see which options are the least used and remove those as well. I suspect "Help" is almost never clicked, but maybe I'm overestimating the competence of the average noob.

The Carrack is amazing. Totally worth the $350 I paid for it.

The homepage, forum and wiki will be going offline for about 5 minutes on 2020-02-09, between 09:00 and 09:15 UTC.

In your local time (if you are logged in and have your time offset correctly configured), this is:
February 09, 2020, 09:00:00 AM


We will be updating to the latest version of SMF at this time. Due to changes in SMF, this will require everyone to log in again the first time they visit the forum after the update.

At the same time, we will install security updates on the server which hosts the homepage, forum and wiki. These will be non-disruptive to functionality, as the server is running a stable OS release that gets critical fixes only.

As all things must with Parsifal, the adventure ended with death and destruction. We exploded when Parsifal rammed us into a rock at about 50 m/s, then he pondered why that would cause us to die.

I did not ram us into a rock. We came over a hill and got some nice air, and exploded when we came back to the ground.

Dell was, last I checked, a good brand.

They're good at servers and monitors. They're shithouse at PCs.

SMT is not a bad idea.

As usual, sweeping generalisations are worse than useless. SMT is not a bad idea in principle, but most software is not designed to take advantage of its shared L1 cache, which means that leaving it enabled often makes things slower, not faster. Two unrelated tasks running on the same core means less cache for each.

Intel's version 'hyperthreading' is also not a 'bad idea'. Intel's problem is that it left their chips vulnerable to Spectre, Meltdown and Foreshadow. The fix they applied ruined performance. But that's an Intel problem.

Where do I begin?

First of all, at least some variants of Spectre affect AMD as well. But that's actually not very relevant here because none of these CPU bugs are specifically about SMT. SMT makes them easier to exploit in some cases due to shared cache, but the bugs are fundamentally about speculative execution and cache side-channel attacks.

Turning off SMT will not turn off either of these things, it will only eliminate the possibility of leaking secrets between threads via the L1 cache, making some exploits more difficult and some mitigations more effective. Notably, it does not stop leaking secrets within a thread (hence mitigations like retpoline) or between cores via the L2 cache (an area of ongoing research).

I really have no idea why anyone would buy Intel on a mainstream desktop right now when Ryzen offers so much more bang for buck.

Someone's been drinking too much kool-aid...

Suggestions & Concerns / Re: Dark forum theme
« on: December 11, 2019, 07:21:25 PM »
You can select a theme in your settings, though we don't have a dark one.

In general, though, I'm opposed to pushing this into a user-visible option. If we implement a dark mode, it should activate automatically if the user has configured their browser in dark mode.

What's it the anniversary of? The game's announcement, its beta release?

It's the anniversary of the end of the initial Kickstarter campaign, in November 2012. There is no beta yet, only an alpha.

This should hopefully be better now. Please post here if you still notice problems.
