Подкинули ссылку на проект http://www.nncpgo.org (см тажке статью на хабре.

Подкинули под соусом "это же почти чеширнет". Нет, не чеширнет, и рядом не стояло (и ровно поэтому есть надежда что окажется более жизнеспособным).

Автор проекта ищет противодействие некоторым из тех угроз, противодействовать которым я планировал в проекте "Чеширнет". Я исходил из того, что любая угроза исходящая от злонамеренного государства или корпорации является частным случаем более широкого класса угроз, противодействие которым вообще говоря не является незаконным и нечестным. Например, я считаю что лучшее средство против криптолокера - своевременный бэкап, так как он позволяет рассматривать атаку криптолокера, деструктивного трояна и т.д. как частный случай проблемы "неисправность жесткого диска или файловой системы на нем", куда попадают также и аппаратные сбои и поломки файловой системы при сбое питания. Неважно что испортило тебе файлы. Переформатировал диск, залил файлы с бэкапа и работаешь дальше,

Аналогичным образом я в чеширнете рассматривал проблему блокирования информации на государственных серверах или файрволлах как частный случай нарушения сетевой коннективити. И предполагал переход от прямого получения информации с некоего ее "источника" на получение ее от ближайшего доступного узла у которого она откуда-то взялась. То есть там была цель - исключить понятие сеанса связи вообще. Даже если есть личные сообщения, они отличаются от публичных только тем, что никто кроме адресата не может их прочитать. А распоh-hлзаются они по всем узлам точно так же, как и новости, пока не будут получены адресатом.

Плюс еще тотальная псевдонимность, за которую больше всего проект ругали. Хотя это минимальный уровень защиты от попыток прищучить того, кто распространяет неодобряемый кем-то сильным контент.

Автор NNCP так далеко не заходит. Он предполагает сохранение парадигмы "передачи файлов" и "сообщений", требуюущих установления чего-то типа канала. Только у него этот канал может быть не реалтаймовым (флоппинетом).

Предполагается что отправитель и адресат знают друг друга на уровне "прописали себе в файлы конфигурации ключи друг друга".

При этом про UUCP автор знает (в статье на хабре упоминал), но похоже не слишком интересовался тем как это работало, что такое UUCP maps и что умела uucp кроме доставки почты и ньюсов. То есть что-то я не уверен, что в том виде как оно написано, оно масштабируется за пределы небольшой тусовки друзей.

Почему-то он также отказался от туннелирования через ssh, хотя наряду с флоппинетом и прямыми TCP-соединениями это было бы полезной дополнительной возможностью, позволяющей иногда добитаться до внутренностей иначе недоступных сетей.

Зато это у него уже работает как транспорт для электронной почты.

Но вообще, похоже сама идея "отправить файл" порочна. Она не даст возможности построить полноценную сеть.
Если уходить от чеширнетовской парадигмы "любая информация должна быть скопирована всем, кому не жалко ее хранить", то нужна система вида publish-request. Вроде фидошных FREQ. В принципе, предлагаемая автором идея хранения зеркал сайтов в виде архивов сюда вполне ложится.

Еще о печке

С печной трубой я просчитался, как Дэви Крокет с крокодилом. Почему-то я решил что пять метров трубы это в буквальном смысле выше крыши. Я недооценил покойного тестя, он строил крышу с размахом, с расчетом на мансарду.
Поэтому купленной трубы хватило не на полметра выше конька, как задумывалось, а на полметра выше будущего потолка мансарды. А до конька там еще два метра.

В общем, придется завтра докупать еще два колена. А пока печка стоит, но топить ее нельзя, так как труба оканчивается посреди чердака.

А выглядит эта печка вот так )

The Big Idea: Nat Segaloff

When biographer and historian Nat Segaloff sat down to interview science fiction Grand Master Harlan Ellison for his new book A Lit Fuse, he knew that he was in for a challenge. What surprised him about the process was how much it wasn’t just about Ellison, but also about him.

NAT SEGALOFF:

How do you write something new about someone everybody thinks they already know? A writer who is famous for putting so much of his life into his stories that his fans feel that even his most bizarre work is autobiographical? That was the unspoken challenge in late 2013 when I agreed to write Harlan Ellison’s biography, an adventure that is just now seeing daylight with the publican of A Lit Fuse: The Provocative Life of Harlan Ellison.

I wrote the book because Harlan wouldn’t. He came close in 2008 when he announced he would write Working Without a Net for “a major publisher,” but he never did. Maybe he figured he’d said enough in his 1700 short stories, essays, and articles he’s published over the last 60 years. It wasn’t as if he was afraid of the truth; he always said he never lies about himself because that way nobody can hold anything against him. That was my challenge.

When we shook hands and I became his biographer, I also became the only person he ever gave permission to quote from his work and take a tour of his life. What I really wanted to do, though, was to explore his mind. What I didn’t expect was that, as I examined his creative process, I would also bare my own.

When you sit down with someone for a conversation, it’s fun; when you sit down with someone for an interview, it’s serious. Harlan has been interviewed countless times and he has always been in control. This time, I was. I had to get him to say stuff that was new, and I had to go beyond where others had stopped.

A Harlan Ellison interview is a performance. He will be quotable, precise, vague, and outrageous. He takes no prisoners. He will run and fetch a comic book, figurine, photograph, or book to illustrate a point, all of which breaks the mood. My job was to get him to sit still and not be “Harlan Ellison” but simply Harlan.

Harlan is one of the few speculative fiction writers (along with Ray Bradbury, Isaac Asimov, and a handful of others) who became public figures. Part of this stemmed from the quality of his work but much of it was created by his being, as I kept finding in the clippings, ““fractious,” “famously litigious,” and “argumentative.” Indeed, most of the stories I found during my research could be divided into two categories: “What a wild man Harlan is” and “I alone escaped to tell thee.”

Balderdash. What I discovered was a man who takes his craft seriously and fiercely defends others who labor in the field of words. An attack on them was an attack on him, and an attack on him was not to be deflected but returned in kind. “I don’t mind if you think I’m stupid,” he told one antagonist, “it’s just that I resent it when you talk to me as if I’m stupid.”

Even though I had final cut, I ran whole sections past him to get his reaction. He never flinched. In fact, he challenged me to go deeper. It was almost as if – and don’t take this the wrong way – I was Clarice Starling and he was Hannibal Lecter — the more I asked of Harlan, the more I had to give of myself. Both of us put our blood in the book even though I am the author.

Купил в Бужаниново печь Огонь-батарея. Поставил в огороде и топлю. Там в по инструкции необходимо сначала в течение часа протопить печь на открытом воздухе. (в смысле я уже оценил с каким ароматом испаряется там транспортная смазка)

Теперь надо трубу через перекрытия проводить и оборудовать в комнате пожаробезопасное место под печку.
Благо все необходимое для этих целей продавалось там же, где и печка. (и в сумме стоило столько же).

Правда, я немножко недоглядел и вместо просто Огонь-батареи-5 взял Огонь-батарею-5Б. Отличается наличием водонагревательного бака. Правда, в инструкции не написано что нельзя топить без воды в баке.

Но ведь как говорят в Меганезии, "это твой добряк, и он должен делать то, что про него написано". Так что теперь думаю где бы взять бак для горчей воды, который повесить на стенку над печкой. Или лучше прикрутить к ней пару батарей, чтобы греть смежные комнаты? Хотя вот ничего про возможность заливать в бак антифриз не написано, а если не заливать туда антифриз, то зимой придется каждый раз сливать. Лучше уж использовать для нагрева воды для мытья посуды (тем более что когда на печку будет основной спрос, водопровод все равно не работает, а значит и электрический водонагреватель тоже).

Getting Lucky With College Costs

Jul. 19th, 2017 07:02 pm

Posted by John Scalzi

The bill for Athena’s fall semester at Miami University arrived a couple of days ago, and we paid it, and I have some various thoughts about that I want to share.

When I went to college, 30 years ago now, I couldn’t pay for it. I did what the majority of people did then and do now — I cobbled together various sorts of funding from multiple sources. A scholarship here, a Pell grant there, a work study job and loans — and still it wasn’t quite enough when one of my funding sources fumbled the ball pretty badly and I had to ask my grandfather for help (which to be clear, he was happy to provide, with the only provision being that I would write him a letter a month, a request very much in my wheelhouse). I graduated with a fair amount of student debt, rather more than the average amount back in 1991, which was around $8,200. I think I was around 30 when we paid it off.

I don’t regret my college debt — I’m of the opinion that my education was worth what I paid for it and then some — but at the time I didn’t really like having the anxiety of wondering how it was all going to be paid for, and my education being contingent on outside financial forces, over which I had no control. I was lucky I was able to find ways to cover it all. I was also lucky that I got a good job right out of college (in 1991, during a recession), and was always financially solvent afterward. That college debt never became a drag or a worry, as it easily could have been, and which it did become for a number of my friends.

I don’t think scrambling for money or paying down college debt added anything beneficial to my life, however. As much as certain people might make a fetish of having to struggle in one way or another for one’s education, and that struggle having a value in itself, I’m not especially convinced that the current American manner of “struggle” — pricing college education at excessive rates and then requiring students and family to take on significant amounts of debt, effectively transferring decades of capital from the poor, working and middle classes to banks and their (generally wealthy) shareholders — is really such a great way to do that, especially since wages in general have stagnated over the last 40 years, the same period of time in which college tuition costs have skyrocketed, consistently above the rate of inflation. Worrying about college funding and paying off college debt isn’t character-building in any real sense. It’s opportunity cost, time wasted that might be productively spent doing something else educationally or financially beneficial.

So: I don’t regret my college debt, but I don’t think it was something that added value, either, to my education or my life. All things being equal, I suspect I would have been better off not having to worry whether I had enough funding for college any particular quarter, or being able to take the monthly post-collegiate debt payment and use it for something else, including investment. Not just me, of course; I don’t think anyone, students or parents (or colleges, for that matter), benefits from the current patchwork method of college funding, or the decade-long (or longer) hangover of college debt service.

We always assumed Athena would go to college; very early on we began saving and investing with the specific goal of funding her education. Along the way we caught the break of my writing career taking off, which meant the account intended for her education plumped out substantially. By the time it was the moment for Athena to decide where to go to college, we were in the fortunate position of being able to pay for it — all of it — wherever it was she decided to go. So, to go back to the initial paragraph, when that first Miami University bill came up, we were able to cut that check and send it off. No muss, no fuss. We’ll be able to do the same for the other college bills over the next four years.

Which is great for us! And not bad for Athena, who will end her college experience debt-free in a world where the average US student with college debt in 2016 was in the hole for $37,000, with that number only likely to go up from here. But let’s also look at everything that had to happen in order for us to get to that point: We saved early, which was smart of us, but we also had the wherewithal to save, which meant we got lucky that Krissy and I both had work, that in her case her gig included health insurance for all of us and that in my case I was in constant demand as a freelance writer, which, I assure you, is not always the case. We got lucky that the books took off as they did; the odds on that were not great. We were lucky that no one of us got seriously or chronically ill, or that other family crises depleted savings. Athena is an only child; that’s not necessarily lucky, but it definitely was a factor when it came to paying for college. We only have to do this once.

All of which is to say that Athena will be getting out of college debt-free partly because we planned early but mostly because of factors that we had only some control over, and over which she had almost none. She didn’t choose her parents or her circumstances; she got what she got. And in this case, she got lucky.

That’s fine for her. But it’s not a very useful strategy for paying for college. “Get lucky picking your parents” should not be the determining factor for whether you leave college debt-free, leave with tens of thousands of dollars of debt, or can’t afford to go to college at all. Every single one of those circumstances can have a substantial effect on how the rest of one’s economic life will go — and how the economic life of how one’s children will go. There’s a reason why in the United States, home of the “American Dream,” it’s actually pretty difficult to move up the social ladder. Yes, I did it, but I also don’t pretend I didn’t get lucky — a lot — or that my path is easily repeatable. Take it from someone who is living the American Dream: It stays only a dream for most of those dreaming of it.

I’m proud that we can pay for our daughter’s college education. I’m also well aware how many things had to break our way to be at this point, which just as easily could have gone another way. It would be better to live in a world where luck, one way or another, is not a salient, determinative factor for whether one can afford college, or whether one can graduate from college without debt. In fact, that world does exist; just not here in the US. College tuition in most developed countries is substantially less than it is here, including being basically free in places like Germany and France. We could do that here, for state schools at least, if we decided we wanted to.

But we don’t. I know we have our reasons. I just don’t think those reasons are very good.


The Big Idea: Cassandra Khaw

Posted by John Scalzi

Identity issues can sometimes be a bear, as the protagonist of Bearly a Lady finds out — in no small part because author Cassandra Khaw experienced something similar in her real life.

CASSANDRA KHAW:

The first time I came out as bisexual to a partner, it was a mess. What was a passably tolerable relationship became a wasteland of conspiratorial winks, elbow nudges, and endless attempts to convince me to have a threesome with someone, anyone, just pick an attractive person of the same gender.

Thing is, I don’t blame him.

Bisexual representation in media is a fraught topic. More often than not, bisexual people are characterized as wild, promiscuous individuals with thrilling sex lives, perpetually ready to jump into bed with whomever they find attractive. (Not necessarily untrue or even wrong, but that’s a conversation for another space.) Consequently, we end up with people like my ex, who begin quivering with lascivious curiosity the moment they so much as hear the hum of that first syllable.

But we are getting better at it. Crazy Ex-Girlfriend has one of my favorite bisexual characters of all times: Darryl Whitefeather, a middle-aged divorcee who comes out mid-season and proceeds to have a stunningly healthy relationship with his new boyfriend. (That show has its problems, but I will forever love the writers for making sure the queer couple is the happy one.) And genre writing is even further ahead in that department. Take Kai Ashante Wilson’s work, for example, which remarks on polyamorous queer relationships without even the barest breath of hesitation. After all, in a world of dragons and technical-minded gods, what is there to fear about a man who loves a man and also a woman?

I’m digressing.

With Bearly a Lady, I’m hoping to build on that canon. Zelda McCartney is a complicated character, for all that she might sometimes appear like an airhead. She’s been out for a long time; this isn’t a self-discovery story. Instead, the book, which goes into some dark places between the lines, interrogates the idea of expectations, labels, and toxic relationships.

And that is because she is a werebear in a human world, a woman endlessly bombarded by external forces, all looking to chip at her self-esteem for the sake of a quick buck or someone else’s emotional fulfillment. It’s no surprise that Zelda has only half an idea as to which box she belongs. Honestly, a lot of people don’t figure that out. Especially those raised outside of liberal communities.

I’d know. For the longest time, that was me.

(Except for the werebear part.)

So, that’s one of the Big Ideas behind Bearly a Lady. I wanted my main character to be full of internal conflict, certain in her identity but uncertain of the words that one might use to define oneself. A mess of paradoxes and imperfections glued together by bad sitcoms and ice-cream. I’m hoping that, one day, Bearly a Lady might be part of some bisexual teenager’s library, another piece in the puzzle as they figure out who they are. Maybe, Zelda will be an example of who they hope not to be. Maybe, they’ll see a bit of themselves in her. Who knows? That’s not up to me.

Bearly a Lady might be a queer paranormal rom-com with werebears, vampires, and billionaire fairies galore, but it’s also a look into the life of a queer woman who doesn’t always get it straight.

Making Hay While the Sun Shines

It’s not just an old proverb. It’s literally happening across the street from where I live.

And yes, I like it that I write about high-tech futures from a place where it’s not at all unusual to see a Mennonite woman bundling hay using a tractor that’s probably as old as I am, and that the hay will probably go to feed the horses that pull the Amish buggies around here. Welcome to rural Ohio, y’all. We have juxtapositions.

Придумался эпизод в "Под тау-Кита чегой-то не так".

Главный герой где-то исполняет соответствующую песню Высоцкого. Причем скорее всего в Торгфлотовском корабле,
который везет колонистов второй волны. При этом, естественно, присутствуют местные юнги.
(во-первых возраст подмастерья, дети, во-вторых, русский язык - основной язык общения, поэтому могут пытаться вникнуть в слова песни).

И кто-то из юнг цепляется к словам "Корабль посадил я как собственный зад, чуть-чуть покривив отражатель."
И задает вопрос: Зачем, а главное КАК, главный герой песни сажал корабль на атмосферную планету с выпущенным отражателем. И поди объясни мелкому ребенку, что песня писалаль тогда, когда еще не было представления зачем на самом деле в межзвездном корабла отражатель. На фоне этого отражателя, который для торгфлотовского юнги вещь, данная в непосредственных ощущениях, релятивистское замедление времени, упомянутое в конце песни, вообще останется незамеченным.

The Big Idea: Michael F. Haspil

Jul. 18th, 2017 02:18 pm

Posted by John Scalzi

Getting older often gives you a perspective that younger people don’t have. But what happens when you’re immortal? What is your perspective then? It’s a question Michael F. Haspil has considered for his debut novel, Graveyard Shift.

MICHAEL F. HASPIL:

As human beings, we tell ourselves fictions to make it easier to cooperate one with one another.

Sometimes, the fiction is noble. We are all equal and entitled to certain inalienable rights. This story only extends to imaginary lines drawn on a representative map, a different sort of fiction. After all, “We” doesn’t apply to “Them”.

Many times, the fiction is merely useful. This color of light means “go” and another color means “stop”. All drivers must drive on this side of the street. Pieces of paper have value and you can use them to barter for goods. When people stop trusting in those fictions, life becomes hazardous and disagreeable.

All too often, the fiction becomes a source of human polarization. The entertainment we criticize, others adore. The sports tribes we deride are idols to others even though we select them more often due to geography than anything else. Their ties are red, ours our blue, so they are immoral. We don’t understand the methods they use to heal; therefore, they are wicked. They have a different melanin content than we do; their lives aren’t worth as much as ours are. Our god is greater than theirs; therefore, they are evil.

It’s all about tribalism and defining the Other. We tell ourselves stories and then believe them to such an extent we can justify any action.

Viewed from the point of view of hypothetical immortals, or beings so long-lived that for all purposes they may as well be, the numbers of those who belong to their tribe shrink over time, until almost everyone they meet is the Other. Of what concern is any subject when humans change their minds or stop caring about them in a week, a month, a century?

Combine that idea with how many atrocities immortals might witness, as they become more and more detached from those fictions we humans tell ourselves. How many died because they followed the wrong leader? How many burned at the stake because of paranoia? How many mass graves? How many genocides? The immortals would tell themselves a new fiction. Humans don’t matter. They all die, some sooner than others.

The trolley problem is an ethical thought exercise. An observer stands near a switch as a runaway trolley bears down the tracks. On the tracks ahead of the trolley, several people are trapped, unable to move and will die when the trolley reaches them. The observer can pull the switch and divert the trolley to another set of tracks. However, an individual standing nearby will die when the trolley diverts. The problem lies in the observer’s choice of whether to kill one person to save many or do nothing and allow many to die.

As the immortals pass down through the centuries, the trolley problem breaks. Viewed on their timescale, what does it matter if everyone on the tracks dies? Their lives are so short, they are as good as dead anyway. Why should immortals trouble themselves with the lives of beings that end in a relative eye blink? Why should human morals matter? Or human laws? It’s not that immortals are more or less ethical than humans. It’s that over their eternal lives they tell themselves different stories. New fictions, humans aren’t equipped to understand.

Taken from the human point of view, these immortals inevitably become the Other. By comparison, our short lives would not afford us a window of understanding. Their decisions and justifications would be alien to us. What do fruit flies comprehend of human machinations?

If we knew of them at all, we would fear them. We would hate them. We would hunt them.

In my novel, Graveyard Shift, some of my heroes are so long-lived they may as well be immortal and so they share part of the problems I’ve described. Added to their condition, they often make the difficult choices of committing a lesser evil to prevent a greater one. It is a slippery slope. How many times can one justify collateral damage in the name of the greater good before one becomes a new source of evil?

In many other stories, my heroes — a vigilante, a vampire, a shapeshifter, a mummy — would be the villains. As Nietzsche warns, “He who fights with monsters should look to it that he himself does not become a monster.” But when beings survive for millennia, becoming a monster, may be inevitable.

My characters aren’t nice people. On a good day, they are indifferent to the plight of the everyman. Often throughout the story, they do unpleasant things and they rationalize what they’ve done by convincing themselves it was a necessary evil to prevent something much worse. Most of the time, that’s true.

This was a bit of a struggle for me. How could I convey the apathy of immortals and still portray them as sympathetic heroes?

It ultimately came down to their motivations. The need for atonement drives many of my characters. They view their immortality and their continued service to humankind as a sort of penance for sins committed past and present.

It wouldn’t take much to flip the script and turn them into the true monsters other perceive them to be. This is what Matheson’s Richard Neville discovers at the conclusion of I Am Legend. Often, determining who is and who isn’t a monster, is solely based on the point of view and the fictions we tell ourselves.

So, this thunderstorm showed up today, and for about an hour there was nonstop thunder and lightning, so much so that I thought I might go out and see if I could capture some lightning in slow motion.

How did that turn out? Well:

I was pretty pleased with myself, I have to say. And then I came back inside before I got zapped.
