The ant colony is a heavily guarded, nearly impenetrable fortress rich with bountiful resources. Intruders attempting to infiltrate the ant society are immediately discovered via chemical cues, overtaken and dismantled. Nothing gets by, except for the few highly specialized, that have evolved the necessary chemical, morphological and behavioural tools to hack the complex recognition and communication system of the ants. Flying under the ant radar represents a huge boon that not only grants free access to the bounty of the colony—including the ants themselves—but further provides a safe and well-protected harbor to develop and live.

1]. The use of highly sophisticated communication systems is the key attribute that enables ants to act as a superorganism, thereby facilitating their dominance of terrestrial ecosystems [1].

2]. It is thus not surprising that most invertebrate myrmecophiles have converged upon this channel to facilitate some level of protection or integration within the ant society. Indeed, chemically based protection for life with ants has independently evolved in a broad range of myrmecophilous invertebrates (e.g., pselaphine rove beetles [3] ant nest beetles [4,5], lycaenid butterflies [6], and spiders [7]).

810]). Adults of Ponerinae, Nothomyrmecinae, Pseudomyrmecinae and Myrmecinae ants are able to produce stridulations consisting of low frequency sounds (a series of repeated ‘chirps’), by rubbing a tergal carena, called the “scraper” or plectrum (Fig 1, 1A3 and 1A4), against a minutely ridged area, called the “file” or pars stridens (Fig 1, 1A2 and 1A5), placed between two abdominal segments [1,11,12]. Ants produce such acoustical signals for various purposes, including social organization, recruitment, mating, or help request [13].

  • No one is chatting at the moment.
  • Ghan Ghan:
    Symptoms?
  • Ghan Ghan:
    I think the symptoms are typically less severe if previously vaccinated.
  • midnight8 midnight8:
    I have had all of the symptoms, taste is slightly starting to come back, but smell, no. Honestly, just been a little miserable, have never felt in any danger from it. Being trapped at home sucks. lol
  • midnight8 midnight8:
    meh, got a little fever again this morning, guess gonna be a few more days
  • The Helper The Helper:
    I went to Comicon this last weekend I hope I dont get it I feel fine and I am not vaccinated and did not wear a mask
  • The Helper The Helper:
    Comicon really was not packed though like it was in the past. I am not really worried though it was the most people I have been around in a year.
  • tom_mai78101 tom_mai78101:
    Still, getting vaccinated is a good idea. We're getting Delta variant spikes here in Boston.
  • The Helper The Helper:
    I am not against vaccination at all I just have a serious procrastination problem I plan on getting vaccinated soon
  • midnight8 midnight8:
    was kinda same with me, I was gonna do it, and life got in the way.
  • midnight8 midnight8:
    we wore mask in some places, but at 118 degrees outside, little rough. :)
  • The Helper The Helper:
    yeah i had another friend in Vegas talking about that heat damn
  • The Helper The Helper:
    Well I do not think I got Covid from the Comicon

  • tom_mai78101 tom_mai78101:
    Pushed out a new Pokemon Walking algorithm build. With a new system in place, I'll probably start tackling triggers and NPCs,

  • Varine Varine:
    Is it fucking hot everywhere?
  • Varine Varine:
    What's a pokemon walking algorithm?
  • jonas jonas:
    it's an engine for pokemon games that closely emulates the walking behavior of pokemon red/blue/yellow
  • jonas jonas:
    basically if you wanted to implement pokemon yellow from scratch, and you'd want it to feel as close as possible to the real thing, you'd start with that
  • Varine Varine:
    Like from the Gameboy games? I'm not at all familiar with Pokemon.
  • jonas jonas:
    yeah
  • The Helper The Helper:
    I only played the Pokemon games on the Gamecube and Wii and such not on the portables my kids had all those games but I never really played on the portables. Now that I think about maybe once sooooo long ago.
  • tom_mai78101 tom_mai78101:
    That's about right. I'm just emulating that old-school RPG feel on the Game Boy system. If I had more free time, I would definitely want to add more things.
  • jonas jonas:
    I guess you folks were too old, but those games were our childhoods:p
  • tom_mai78101 tom_mai78101:
    Well, I'm about to hit 30 this year, so I'm now officially old.
  • Ghan Ghan:
