MMORPG about educating people on how hacking works
MonDie replied to Unity+'s topic in Computer Science
Who is the target audience? Apparently there exists a genre called "hacking simulation". https://en.wikipedia.org/wiki/Street_Hacker Perhaps it could be made multiplayer if contained within a secure virtual machine. But why not just download Kali Linux (for free) and do home penetration testing with a spare laptop? Educating them is probably a good idea. I speculate that victims are generally unsuspecting and underprepared... Everybody thinks they've "secured" their wifi, but it's only a speed bump to a determined attacker. -
Was this a miracle or a mistake?

Other explanations: sessions hijacking another user on your device (computer) stolen password I know session hijacking can happen with wifi connections, especially public ones. Hit "Sign Out". article on session hijacking http://www.gizmag.com/firesheep-http-hijacking-tool/16726/ boobs -
Oh my, the avatar was completely incidental. Anyway, bye!

Mitochondria in Sperm Defects?
MonDie replied to Endy0816's topic in Evolution, Morphology and Exobiology
I had to be refreshed on that! I sort of skimped on the metabolism chapters. Fertilization and elimination of the parental mitochondrial genome. JM Cummins, 2000 Apparently the "reactive oxygen species" which the mitochondria serve to isolate can damage the DNA, although "the common assertion that mitochondria lack mechanisms to repair oxidative damage to DNA appears to be false (Cummins, 2000)" I initially imagined errors in replication during spermatogenesis, but could sperm mitochondria be more active and thus suffer more oxidative damage? Apparently this was the topic of the last 3 paragraphs of the sciencedirect link, but it looked like jargon at first glance. -
What are the ISP policies anyway? I thought you might find NoCat interesting. Warning: www.nocat.net is redirecting to hackerfriendly.com for some reason.

Goodbye and thanks for all the fish.
MonDie replied to Ophiolite's topic in Suggestions, Comments and Support
Will they be participating just as they did before they left? Moment of truth. On that note, I'll be gone until May. Hoooooly cow! I think I figured out what was driving me mad. Boy am I glad it was external factors! 3... 2... 1... Bye! -
That was exactly it, a strain of mitochondria that mutates so as to heritable through both parental lines. This entails heteroplasmy. It could be deleterious to the organism yet advantageous to the mitochondria. On second thought, the mitochondrial advantage might not be sizeable enough since the paternal mitochondria are still outnumbered 1000:1 even if they can bypass destruction. So yeah, my idea is pretty really far-fetched! The idea was that the species might revert to maternal inheritance after the new strain becomes the norm.

I decided to split this from this thread, where the OP provided this interesting case study. Paternal Inheritance of Mitochondrial DNA (Schwartz and Vissing, 2002) http://www.nejm.org/doi/pdf/10.1056/NEJMoa020350 A biparentally heritable strain of mitochondria might be more fit. What if biparental strains take hold from time to time only to negate themselves after they've succeeded, causing the population to revert to the maternal mode of inheritance? Has this possibility been investigated? I know little about the analysis of the maternal line via mtDNA. My thoughts are this. If such strains are allowed to appear, either they harm the organism too much to succeed—perhaps sperm mtDNA carries more mutation—or the strain quickly negates its own biparentality after succeeding. In the other thread, the OP claimed that parental mitochondria are actively destroyed, but I don't know the mechanism nor whether mitochondria might occasionally bypass this destruction. I'm sorry. I get so "creative" when I don't exercise.

Mitochondria in Sperm Defects?
MonDie replied to Endy0816's topic in Evolution, Morphology and Exobiology
Not quite maternal and paternal mitochondria, but rather a biparental strain and uniparental strains. -
Mitochondria in Sperm Defects?
MonDie replied to Endy0816's topic in Evolution, Morphology and Exobiology
That would be the proximate cause. The OP proposed an ultimate cause, namely, that sperm mtDNA has more mutations. Admittedly, your proximate cause wouldn't be a clear example of adaption. Nice Nature abstract! -

Not that I'm some kind of expert. It's just logic... It would seem that either maternal mitochondria are in an advantageous position, which may have been selected for if paternal inheritance is detrimental to the organism, since lack of genetic recomination puts the mitochondrium at a huge disadvantage to the nucleus, or no adaption was required because paternal inheritance is detrimental to the organism to such a degree that it outweighs the benefit to the mitochondria anyway, since the mitochdrium's fitness is affected by the organism's fitness. -
I thought I would add this study just to pile on the evidence even more. The Eyes Have It: Sex and Sexual Orientation Differences in Pupil Dilation Patterns (Rieger, Savin-Williams, 2012) "An infrared gaze tracker automatically recorded for each participant both pupil size and degree of dilation. (Rieger, Savin-Williams, 2012)" Dilation to same-sex was positive scored, to opposite-sex, negative scored. See Figures 1A and 1B. They explain how only the female data exhibit a "curvilinear" relationship. In the female data, opposite-sex preference levels off so that heterosexual females never exhibit as strong a preference as lesbians and men. This strand of the discussion addressed whether females like gay men, but perhaps there's more to be gleaned. A woman who's had same-sex relationships may still be as heterosexual as any other woman. Who knows, she might even be healthier!

You did it correctly. Unless they're acid-fast or endospores, either the decolorizer will break down the violet-stained wall and they will stain pink/safranin (-), or they will retain the crystal violet (+). Good luck! Gram is a proper noun!

That's not what I want. IP address might be nice too! Maybe have it optional! I think logins could probably be tracked more reliably.

The time of your last login informs you of whether anybody else has obtained your password, and possibly passwords to other more important accounts. Does SFN remember this information? Can we access it from our accounts?

Corrected. You're talking about the Gram-negative in both cases. The Gram-positive were bacilli! In my inexperienced opinion they looked like diplococcus, but a pair isn't really enough to reveal all the planes of division, and there are some spots where they look more staphylo-. How do you know all the Gram-negative cocci were of the same strain? I think I even see some Gram-negative bacilli underneath the Gram-positives on the middle-right.

The TED talk. see 4:30 Why do you think they require an extraordinary explanation? Maybe they're just ambiguous.

Sounds sneaky!

So rather than merely forwarding the packets, the server will accept - reformat - resend? Have you heard of mobile hotspots such as Mifi? If it's sending the information back through the internet, then why? Is it adding another layer of encryption?

The link between a stronger Christian identity (among americans?) and various prejudices is well established, but there's also what happened under the USSR's state atheism. Could nationalism mediate the relationship? Only studies I found regarding nationalism and prejudice, but neither tell the results. http://www.ncbi.nlm.nih.gov/pubmed/24003580 http://www.ncbi.nlm.nih.gov/pubmed/19580560 Any relevant resources would be much appreciated!

I'm probably way way way underqualified for this, but could they be acid-fast? Acid-fast stain. http://en.wikipedia.org/wiki/Acid-fast http://www.ncbi.nlm.nih.gov/pmc/articles/PMC269558/?page=1 Endospores won't stain either, but I don't know how you would test for them.

I would qualify it with "at least" since some cases may go unrecorded. You could try to estimate what percentage of cases go unrecorded, but I can't help you with that.
