Journal Journal: Slashdot issues 1

For many years now, the side bar on the front page has been linked to DustyM's account but to my account on all of the secondary pages. This has been annoying and I've given feedback on it a few times with no response.

Does anyone know of a way to fix that damn sidebar? If not, I have been using the workaround for a long time now, but it is exceedingly irritating.

Journal Journal: Transcribing WW1 biography 5

My great great grandmother wrote a biography of her three brothers killed in WW1. I'm typing it all into a LaTeX editor and will be adding a family tree along with a sketched outline of their lives and newspaper clippings.

A best-seller it ain't, but it may interest a few here as these guys show autistic traits and are geeks from just over a century ago.

Journal Journal: Review: Bird of Prey 4

TL;DR version: 80s dystopian techno-horror geekfest with relatively accurate portrayal of cryptography and hacking.

Long version: Pretty much the same as above. It's a low budget BBC production that scores highly on accuracy of methods, exploits and technology of the era, insofar as TV ever gets.

The premise: a low-rank civil servant, tracking down bank fraud, discovers a trail of blackmail, corruption by intelligence services, deliberate weaknesses in security and criminal gangs operating with impunity.

By season 2, he's keeping himself alive the same way the Wikileaks journalists did, his wife has what we would call severe PTSD and the body count isn't slowing down.

Given trauma was barely understood in the 80s, the portrayal there and the bouts of temporary insanity are extremely close to what happens, again allowing for this being TV drama and not a psychological documentary.

The storyline deals with cryptography, surveillance society, backdoors and institutional corruption. All hot button issues of today. It even covers the inevitable issues of DIY security.

The conspiracy aspect is a trifle OTT bit, again, it's TV. It has to be to have a program.

It's geared to nerds, geeks and dystopia lovers, though, rather than the mainstream. I saw more reviews in computer journals than in TV guides.

It's the sort of show that would really need updating to be watchable by modern audiences, but fans of older shows would likely enjoy it.

It wasn't unusual for the time, which is the great thing

The 80s were a time for really bleak geek television - Codename Icarus (for the younger viewers), Edge of Darkness, Terry Nation's Survivors, Threads - all productions in this decade.

(Even late 70s had some dark stuff, Blake's 7, The Omega Factor, Day of the Triffids, and ABC/Central's Sapphire & Steel were not light watching. You have to go back to the start of the decade and Doomwatch to see a plausible contemporary dystopia.)

The stuff of a thousand bad dreams, these shows.

Journal Journal: Teaching history via RPGs 3

There's a new RPG pack under development, called Carved In Stone. Well, it's called an RPG pack, but basically it's a fairly comprehensive history lesson about the Picts that can be used in roleplaying games. This is quite a neat idea and it got me wondering.

There were, at one point, quite a few historical wargames (Britannia, Decline and Fall, etc) but they were mostly about large-scale strategy rather than the history itself (which was mostly an excuse for blowing up other people's counters). History lessons via roleplaying games sounds quite an interesting approach and could be used to cover all kinds of events.

The expansion pack isn't out yet (it's still in kickstart) but there's enough information about it to get a good feel for how much depth there is in there. If it's done well, it could be very effective in the same way "...and then the Huns came and beat the sh*t out of the Romans before leaving again" isn't. Unless you're a Hun.

I'd like to get people's views on the use of roleplaying games and which system would be best for such gaming. Rolemaster? Call of Cthulhu? The ever-present Dungeons and Dragons? ("My 20th level mage casts a fireball at the fleeing Scots" sounds ahistorical.)

Journal Journal: Consumer Genetics, the current state of play

Ok, so let's start be defining a few terms, as it is obvious from Facebook genetic genealogy groups that people are truly ignorant on the subject. (Not that I believe this is common on Slashdot, where we're all much more knowledgeable.)

First off, most genetic testing is NOT carried out by sequencing all of your DNA, a widespread belief that resulted in outrage on one Facebook group when I pointed that out.

The vast majority of consumer testing is done by SNP genotyping. They look at very specific genetic markers and see if those markers have changed from one base pair to another. That's the only type of mutation looked for and they typically look at only a few.

So we've our first way to group companies: sequencing vs genotyping.

SNPs (single nucleotide polymorphisms) are, as mentioned above, one type of mutation. Another is called STR (short tandem repeat), where a block of DNA is duplicated.

FamilyTreeDNA does both STR and SNP testing, STRs mostly for the Y chromosome. Both can be used for family history.

Most labs, though, use only SNP tests. It's quicker and cheaper than counting repeats but with many of the more interesting ones covered by patents or kept private by other means, there's a lot more secrecy involved.

(Note: This has doubtless led to a lot of unnecessary deaths, as genetic markers indicating a high probability of getting certain forms of cancer are being milked by private companies for profit. Few people get more than one test, so most people won't know if they carry such markers and can't take action in advance.)

So the second piece of jargon is SNP vs STR.

Finally, we come to the different areas of DNA. There are regions that are especially good for ancestrial reserch (mostly non-coding DNA), then there's the exome (which is where most of the protein coding takes place), you've telomeres (suicidal buffers between chromosomes, which have a function in longevity), and so on. I won't list them all.

The Y chromosome is particularly good for ancestry, but only has 9 coding genes left in it. It's possible it will vanish in time, but it seems to be fairly stable for right now.

Most companies test only DNA that is good for ancestral research in the autosomal regions (aDNA, the regions outside the sex chromosomes). This allows you to identify anyone who is genetically connected, but because you (on average) get just under 50% (remember, there's mutations in each generation and that DNA comes from neither parent) of your DNA from each parent, the distance you can track depends on how many markers are tested (very few). Reliability falls off sharply.

YDNA (Y chromosome DNA) tests only test for paternal ancestry, but if two people have a common paternal-line ancestor, it's a lot more precise once you're past about second cousins. It's popular with anthropologists as it's very good for tracking how men have migrated.

mtDNA (mitochondrial DNA) is only inherited through the maternal line. Again, it's very popular, this time for tracking how women have migrated. There are certain forms of mtDNA that are linked to health benefits and others to genetic diseases, so this one tends to be the most controversial of the ancestral DNA tests. It also changes very slowly, so you don't get high resolution on population movements.

These two (YDNA and mtDNA) tests can tell you a lot about whether societies are open or closed, and whether it was men who travelled to find partners, women, or both. So we can know something of the culture of even long-extinct societies.

The data I have been able to find is for 2019. It shows: Myheritage tests for 702,442 autosomal SNPS, AncestryDNA for 637,639, FTDNA for 612,272 and 23andme for 630,132. This is out of a total of 3 billion base pairs. So the best test that year looked at 0.0023% of the genome.

ISOGG produced a chart as well, but it's far older. Their chart is dated around 2013.

Since you inherit a random 50% from each parent, the assumption that this is statistically meaningful for such a small fraction of the DNA is questionable. It seems to work adequately, but I'm not sure what the error bars are.

FTDNA also tests up to 111 STRs on regular tests and 600+ STRs for their "BigY" (it depends on the quality of the genetic sample).

Companies that do sequencing sometimes offer partial kits (in the order of tens of millions of SNPs) or full sequencing (which is what the same suggests). These are rarer and more expensive.

Most DNA companies allow you to access the raw data, some only allow it if you pay vast sums of money, and some don't allow you to at all. Always check in advance.

When you download your own data, you can use public databases to search for matches (either for relatives or genetic conditions). The quality of public databases is less controlled, both in terms of privacy and quality of data. However, corporate databases will usually be smaller for both types of data and will also usually not contain data from rivals. If you want broad data sets, public databases are the way to go.

I've only tested with 23&Me, FamilyTreeDNA, CRI Genetics and Nebula Genomics, so can't tell you anything much about the quality of the other companies.

(Ok, I also tested with uBiome, a microbiome testing company in the US, but they had their computers seized some time back due to fraud. I have no idea what happened to my data on there, or whether there's a way to access it.)

The quality seems to be reasonable for all four.

FTDNA is the most expensive for a lot of things, but has less of a sticker shock than Nebula and gets more data than 23&Me. It looks like there are a few companies that are better for ancestry but it's one of the best and the one the Genomics Project used. They're the only ancestral company that gives you STRs AFAIK and they give you a much more detailed evaluation of haplogroups than anyone else I've tested with.

Nebula does up to medical grade (100x oversampling) DNA testing, so if you want results a hospital will trust, that's where you part with a vast amount of money.

23&Me is good for a lot of medical stuff and if you want to help with research is probably the best.

CRI Genetics produces a lot of data with much higher reliability than most of the others, but you can't access the raw data and their databases won't be as extensive. However, because you can't access the raw data, you have to test with them to compare against their database.

Journal Journal: Tea 7

I have now passed the total of 30 different black teas. Not fruit, not spice, not herbal, not even green, white or red tea. Just black teas. No, blends like PG Tips and Yorkshire Gold don't count either.

Why so many? Aside from being my current monomania, it's because I'm fascinated by how different they are.

I couldn't tell you the chemistry that makes that difference, nor could I tell you what difference it makes in terms of the various compounds affecting alertness or sedation. (It contains both), in terms of health benefits or even in the simplest term of how water is retained in the body.

But I'm determined to find out at least some of this. It'll have to be on my own, as essentially no research is being done on the subject, and I've no idea of what that'll require beyond a very good gas spectrometer (I'm going to have to count molecules, not atoms).

But I think it would be fun to find out, and definitely worth doing as long as I can figure out how to (a) control the parameters, and (b) afford said piece of gear.

Journal Journal: Not a Racist Country? Really? 23

A black man is gunned down by police for handling a toy gun in a Walmart. A gun that Walmart was selling.

http://www.vox.com/2014/9/24/6839953/video-john-crawford-walmart-police-beavercreek-ohio-toy-gun

But this white guy can carry a real, loaded rifle (and body armor) in front of a school, refuses to show ID to police and nothing happens.

Open Carry laws are clearly meant just for white people. Laws that only apply to one race are the definition of racist.

Journal Journal: More Than Enough - Comcast declares war on Tor 31

If you haven't dumped Comcast yet, you better hurry:

http://www.deepdotweb.com/2014/09/13/comcast-declares-war-tor/

Reports have surfaced (Via /r/darknetmarkets and another one submitted to us) that Comcast agents have contacted customers using Tor and instructed them to stop using the browser or risk termination of service. A Comcast agent named Jeremy allegedly called Tor an âoeillegal service.â The Comcast agent told its customer that such activity is against usage policies.
The Comcast agent then repeatedly asked the customer to tell him what sites he was accessing on the Tor browser. The customer refused to answer.
The next day the customer called Comcast and spoke to another agent named Kelly who reiterated that Comcast does not want its customers using Tor. The Comcast agent then allegedly told the customer:

"Users who try to use anonymity, or cover themselves up on the internet, are usually doing things that arenâ(TM)t so-to-speak legal. We have the right to terminate, fine, or suspend your account at anytime due to you violating the rules. Do you have any other questions? Thank you for contacting Comcast, have a great day."

Journal Journal: The Trolls 81

Wow, it's been 15 years but I've finally got my own personal troll! :-)

I must apologize to everyone I've ever called a troll now that I've seen a real one. Yeah, there are trollish comments, but this... it's a different league. If you ever wondered who these brain-damaged morons were who set up geocities homepages with blinking purple text on blue background with red dots in Comic Sans - that kind of different league.

Now it does make me wonder about trolls in general. Has there been a study on this? I really wonder if psychologists have tackled this because quite honestly, you cannot be mentally stable and post in this and this content at the same time. So I do wonder if trolls on the Internet (the real trolls, not the people occasionally posting something stupid) do have a mental problem. It definitely looks like it. Probably insecurity issues, definitely an exaggerated need for attention, might be related to borderline syndrome or schizoprenia.

And, of course, the Internet provides:

As someone who has had to deal with family members suffering from mental illness, let me tell you that it's not funny. So despite the fact that they are, in fact, obnoxious, aggravating assholes, these sad little fucks also need help and their miserable little existence is not something you'd want to trade for yours, no matter how much you think your life sucks. Trust me, with a mental illness on top, it'll suck more.

Obviously, we can't offer therapy to people who usually comment anonymously and will often go to great lengths to avoid being tracked down. What we can do, however, is get a better understanding for how they act this way (they can't help it, mental illness is stronger than your conscious mind) and that the best thing we can do for them is to not continue the feedback loop. "Don't feed the trolls" - old wisdom there.

The last link in that list contains a few more ideas.

Now that I'm at the end, I kind of regret the smiley face at the top. But I'm leaving it in because this journal entry is a bit of a journey, even if it is short. Thanks to some Internet resources, a bit of research and connecting the dots, I've come a short way, changing my mind a little on this particular sub-sub-sub-part of life.

-----

A short additional statement on how to treat trolling. From what I've gathered from the resources above, a few comments (both here and in the various spammed threads) and my own life experience:

First, don't feed the trolls. Most of them seek attention, so if you stop giving it to them, they become frustrated and go away. Notice that they seek attention, not validation. A rebuke or an angry rant or even a shootout of personal insults satisfies them as much as anything else. Much like the old PR saying "there is no negative publicity", it is all about the attention itself, not about its content.

Second, stand your ground. Do not leave the site or stop commenting just because you're being trolled. It takes a bit to do that, yes. Trolls consider it a "victory" if they shut you up, either by simple flooding or by frustrating you enough to disappear. In their twisted minds, it gives them validation and somehow proves that they were right.

Third, if you see someone else being trolled, give them support. Doesn't take much - a single sentence is more than enough. Someone under attack by a real troll is being flooded. The troll will commonly post under multiple aliases or otherwise attempt to appear as more than one person. Psychological experiments such as Solomon Asch's show how we humans as social animals experience conformance pressure. So give that other person support by showing him that the flood he's getting is no the only opinion around. It doesn't matter if he consciously knows it's just one troll, the pressure is subconscious.

I'd like to have comments disabled on this journal entry, for obvious reasons, but you can't publish a journal entry with comments disabled, so... 1000:1 bet that he's stalking the journal as well and will add his drivel below?

Also, if the formatting looks atrocious, turn off beta and revert to classic. Seriously.
