Chaos in the sub: For the 2nd time in a month, Reddit has deleted a moderator of the sub, a user who also was contributing a ton of articles to the sub.

This deletion also purged the user's articles from the sub, along with any conversations that were going on in those posts.

There was no warning by Reddit, just a permanent deletion with an opportunity to appeal but the appeal is never granted and nor even responded to.

I'm not sure if I can con her into becoming a moderator again, so as usual, we're upping our constant search for users -- and moderators.

We need YOUR help!

9 Upvotes

We need your help! We're trying to create and popularize an entire set of "alternative" sub-reddits.

These sub-reddits all end in a "2". So just take the name of a huge, multi-million-user "main" sub-reddit and add a "2" to the name -- e.g. /r/Politics2, /r/WorldPolitics2, /r/News2, /r/WTF2 and so on.

These sub-reddits are smaller and have fewer rules than the huge mega-million-user large sub-reddits. Our idea is to create a set of friendlier sub-reddits with an emphasis on civility and not personal insults and ad hominem attacks.

But we need your help!

We need your time, your posts, your comments and we need you to mention our alternative sub-reddits in other places and to tell others. (Basic "publicity.")

  • Please post submissions!

  • Post comments and reply to others.

  • Help us popularize these alternatives to the heavily censored and sometimes too heavily trafficked mainstream subs by telling others of our existence.

Together we can develop another option inside of reddit.

Want to become a moderator? Or help run your own "2" alternative sub? There are possibilities for that too.

Interplanetary-Frogger: Hohmann Alternate Transit Methodologies

1 Upvotes

I was noodling around with an idea in my head after hearing Musk discuss the launch window limitations for a interstellar transit to Mars, and decided to see if I could make a viable solution of it. With my original idea in mind, I fired up Antigravity with Gemini Argon 4.5 High to create a simulation to answer the question:

How to get to Mars faster.

Full disclosure: mathematically, it's pretty sound - though I'm not sure I'll be so bold as to call it perfect. I did add PySim and PMMath modules to my IDE to validate the deflections and 'lilypad' concepts. Economic viability, logistics, manufacturing - none of that was considered at all, intentionally: no point trying to solve the hurdles if the race isn't even worth running. I think I've got to a stable V1 concept, but I'll leave that to the comments and responses.

If anyone is interested in seeing it - you can find it here: https://hobbyaquatics.com/interplanetary-frogger/

This should render with any device, but do note that it is best from a desktop because it  draws the orbit view at 2–3× resolution, which leans harder on the graphics card.

Any feedback or suggestions for improvement of the concept are graciously welcomed. Anyone who wants to harsh on the infeasibility of it - you're welcome, too.

Previously posted to r/astrophysics, but their mods get pretty cranky about anything not published from an academic institution.

Ants love sweet things, but...

1 Upvotes

Ants love sweet things, but as shown in this video, apparently 5 out of 7 died in an environment full of sugar. Does anyone know the mechanism behind why ants actually end up weakening when surrounded by so much sugar?

In contrast, all 7 out of 7 reportedly survived unharmed in an environment filled with Agri-Gel.

AI assisted New Data Compression method(s)

1 Upvotes

I used Claude to run extensive tests on my theories, methods, and concepts. The result was the Harrington Compression Method, or HCM for short.

In The Canterbury Corpus I took 9 of the best from Bzip2, xz, and ZPAQ. In fact ZPAQ was crushed in this test. The HCMv3.3 completed today as were updates to Bzip2 -9 and xz -9e. In every case I increased compression and decreased the time to decompress a file. In some cases the files take longer to compress, but since it is often compress once, send hundreds to millions of the compressed file, then decompress, this was seen as a non-issue.

The majority of the Canterbury Corpus was beaten by HCM or one of the Harrington Insight mods.

HCM stands for Harrington Compression Method and the hi stands for Harrington Insights. No new methods were used, only new looks on how to use them and apply them together.

This is prior to the Harrington Insight mods, as you can see the HCMv3.3 was significant in the tests.

The above table shows how my software does for the various compressions comparing ZPAQ, xz, and bzip to HCM.

More importantly is the energy consumption. Note the differences for them can switch, I am great at all but four, three where my system lightly loses and one where I essentially tie with the competition.

In joules the energy required is a helpful means to understand how a compressor will do at the industrial scale. Steam downloads, Microsoft Patches, all of it gets compressed and then decompressed after being downloaded. This system does not care about the energy of compressing, only transmitting and decompressing is important. The HI types help but it is not a huge gain at ~1.4%.

That means, since the energy consumption is so low of a difference, the final factor would be storage on a disk, and since I win all but two, it is decidedly one sided there.

I uploaded it all to https://github.com/CombaryMaker/Harringtons_Insights

Overall this is a minor upgrade, but a real one, to the types of compression going on. I would not suggest it is backwards compatible.

I am quite open to questions, it is a MIT License for my stuff (check for their licenses though, I am only showing the research here), and I am quite willing to talk about this all.
