Writing Partner

I am hoping to write with somebody on an experimentation novella of sci-fiction. English speakers are preferred, will be an informal schedule, focusing on plot and setting, symbolism is a lesser aspect, professional quality, and will self edit their work. I have a plot and idea, would like to write the novella using a tennis style of writing alternating chapters. I may self-published (Lulu.com). Working under the CC licenses. Wouldn't at all mind having a long term writing partner. Comment here or email me at 94johnjy94@gmail.com! :D

Writing biography?

Написание биографии. Для начала нужно определиться с тем, что или кого будете описывать. На пример - это будет Сальма Хайек. Начнем с подбора фотографий в интернете, которые нам понравятся. После этого начинаем сбор информации и о том где родилась актриса. Кто ее родители, а так же описываем ее детство. Юность. Потом обьясняем читателям из за чего она решила стать актером. Далее описываем начало карьеры. Так же указываем все неудачи. После этого как она поднялась на пьедестал. Описывать личную жизнь нужно осторожно и подбирать хороший сайт на котором есть правильная информация. Детей не забудьте указать, если конечно они есть. Разводы тоже можно указать. Заканчиваем биографию всякими фактами. Пример: Сальма говорит на английском, испанском, арабском и португальском языках. Сальма страдает дислексией. Она одна из двух мексиканских актрис, которые номинировались на премию «ÐžÑÐºÐ°Ñ€». Вторая — Кэти Хурадо в 1954 году. Вместе с группой Los Vega записала песню La Bruja, вошедшую в саундтрек фильма «Ð¤Ñ€Ð¸Ð´Ð°». Также записала песню Siente mi amor из саундтрека к фильму «ÐžÐ´Ð½Ð°Ð¶Ð´Ñ‹ в Мексике». Отказалась от роли в фильме «ÐœÐ°ÑÐºÐ° Зорро» после того, как Роберт Родригес оставил проект в качестве режиссёра. В итоге роль исполнила Кэтрин Зета-Джонс. 11 декабря 2005 года в Осло вместе с Джулианной Мур вела ежегодный концерт по случаю вручения Нобелевской премии мира. Её отец ливано-иорданский управляющий нефтяной компании; а мать, Диана Хименес — мексиканская певица. Её отец, Сами Хайек Домингес, баллатировался в мэры Коатсакоалсоса в 1997.

Write Up Deleted

I just spent 4 hours writing up a really kick butt guide using the new editor.  I went to publish.  Published it.   I had something like 15 steps written out, and then I had three.  Just three.  The rest were gone.  No idea why or how. What happened is that I started writing in the "old" editor, but stopped three steps in before switching to the new editor.  Seems as if the system didn't like that. Oh well.  Looks like I wasted four hours of my time.

How not to write complaints

As I see comments complaining over certain aspects of projects often enough, here is why some of these quips are utterly futile in their nature and go unacknowledged by many. Here's one posted a few days ago: "It's confusing for people without a technical understanding." This comment was posted to an instructable with 17 steps and several dozens of photographs. Because there is no indication of what the problem is, this statement is all but meaningless. There is nothing on which to base a response with help tailored to the commenter because he has not explained his plight's origins. If you are going to make a complaint or ask a question, identify the relevant subject. That will grease the skids for any correspondence that follows. Without it, your bid for a chat is more complex needlessly.

help writing a story?

I know that this type of question has been absolutely done to death (where did that expression come from anyway?) but I have a premise for a science fantasy story. I have a skeleton of an Idea of what the story will be, but here's what I have so far. Time: unspecified. Disaster: sometime in the distant past, a disaster the likes of which hadn't been seen since the biblical day's of old was swiftly falling upon the land. Somewhere in in the middle of the pacific ocean, a poisonous green fog begins to seep off of an unremarkable island, volcanic in origin, about a square mile in size. This wouldn't have been a problem, since such a small amount of fog would have eventually lost itself in the vastness of the planets atmosphere, and the stuff it was made of was largely biodegradable through a variety of ways found in nature. So it was sensationalized for a while, with the usual kerfluffle, and then it was quietly forgotten as some new crisis arose, banished to the shady corners of science, with only the ocassional visit from some obscure science foundation sponsored trip. And that was that. That is, until, somebody noticed it was growing. And  sure enough, it seemed that, contrary to what the specialists said, it was slowly, steadily, patiently growing, getting thicker and thicker. Eventually, (about four years) an expedition was chartered to go into the now opaque cloud. Here is one adventurers account of what it was like. " After a looong and boring flight, we neared the destination. Looking out, all I could see was what looked like a big greenish-brown mound. the truly weird thing about it was that it's edges weren't very well defined and looked like what you would expect something like a giant cloud of steam would look like that was left to dissipate, but there was a definite edge to it that billowed like a great sheet of canvas in the wind" Note: this is not the end of the story and setting, just my present atention span. I promise to include more of the setting and premise in the comments, but for now i'm completely fried.

To be or not to be upset

So, with recently finding out that tons of people's instructables had been published without their permission on a paid subscription site, I decided to google my username and see if anything came up. This is obviously something everyone should do from time to time, and I figured it was time to give it another go. In the image search, I found an image I didn't recognize and clicked until I found the source of the connection to my username. A seemingly reputable website has written an article on one of my ibles. At first, I was excited. It was cool that someone saw my work and thought it cool enough to write about it. However, that joy turned to turmoil when I realized that the article wasn't a short description accompanied by one or two images. It is a full rehash of my ible. Basically, anyone that sees the article can follow the links to my version (there are several), but the author of the article has really not given them any reason to do so. They've taken most of my images to re-write my ible without asking or notifying me. They didn't break the CC license by writing their own version, but I believe they did when they took all my images.  What do you think? Would you be upset and ask them to change or remove the article, or chalk it up to promotion and be excited to see your work spread? By the way, there have only been 138 hits on my ible from that website. The article My ible

How to Write & Submit Questions

I haven't been a member of this community very long but I've enjoyed looking at many of the posts and have learned a thing or two.  I also enjoy helping people by posting comments and answers to questions.  One thing that I've noticed is that a significant number of posters write very poor questions.   Not that the question isn't valid, but rather the phrasing or context is not clear.  Some of them remind me of the old programming axiom GIGO - Garbage in equals garbage out.  Posters don't get good responses because they didn't form a good question.  The curious would get much better answers if the questions were clear as to the information requested, the context, conditions, the desired outcome, etc.  One might start with the old "5 W's" (who, what, when, where, & why and perhaps how and how many).  A little extra effort in phrasing the question and perhaps some good manners (please & thank you) will result in better responses and more community participation.   Perhaps as a collaborative effort, would there be value in developing an instructable on how to write a question?  Not as a set of rules or a format, but as a general guide as to what information should be included.

Magnetic reactive writing pad.

I need help figuring out the best way to do the following. And i have been searching and apparently I don't know the proper way to phrase this to find the information on google/instructables. What I need -  a small surface that is magneticly reactive, to be able to Write with a magnet. It also needs to be able to be erased, probably also with a magnet.  I want it to be decently small, and I am sure there is material out there, but i don't know what it is.  And no I dont want a dry erase board.  Think of the Magnadoodle, where it would react to what is being drawn with the magnet, but i wnat something that is more like a Slate, and not a series of pockets that have a certain amount of filaments that react to the magnet.  I am sure there is some kind of material like this out there. I just dont know what to call it, and i need to be able to make it decently small and thin.  A basic idea, is like an impression pad. If you wrote something on the top sheet, or a couple of sheets of the pad, under the sheets, it would take an impression of it, (assuming it was written with a magnetic pen), you could then see what was written on the sheet originally, on the surface. Also it would need some way to be erasable so it could be used again.  A concept like carbon paper, but with magnets.  Please point me in the right direction, I am very hands on, and a long term DIYer, i just need to know what basic material i need to accomplish this. I know it exists, i just don't know what to call it.

Writing a useful bug report

From time to time, people have trouble with the Instructables site. Often they have found a bug that we need to fix. If this happens to you, here's how to tell us so we can fix it as soon as possible.Search!A lot of times the bug you found has been reported already. Do a quick search in the bug forums to see if you can find an existing report. There may be a workaround that someone has posted, or an estimated fix time. If it's already been reported, go ahead and comment on that rather than making a new report.Check, as well, if the problem is something on your system that we can't do anything about. For example, Firefox users may have installed the Greasemonkey extension, and some Greasemonkey scripts cause unexpected behavior on Instructables.Details!Provide a lot of information, including:the OS and browser you're usinga link to the page you were on, and/or the page before, where things were still OKthe error message you got, if any (copy/paste if possible)anything else you can think of that seems relevantProcess!In order to fix the problem, we have to be able to see it happen - we have to be able to reproduce it. Write a step-by-step list of the things you did to get the problem. If you don't remember exactly, try doing what you were doing again, slowly, to get the bug a second time. If you can't get it to happen again, we probably won't be able to get it to happen either. Sad but true.Patience!Some bugs may take a while to fix, either because they're very difficult, or because other bugs and features are higher priority. In general, if you can't do something you should be able to do, we'll fix it as soon as possible. Things that just look weird, or have alternate ways to be done, we'll fix later.

How does a computer "write" something... to memory, a registry, etc...? Answered

I know that every computer has a CPU. I know that every CPU has it's own Instruction Set, or... set of things that it can do: CompareAddJump toInOutetc...I even know a fair amount about how a CPU interacts with RAM along the Data Bus and the Address Bus with Set wires etc, and how a CPU's ALU (Arithmetic Logic Unit) stores data temporarily in "registries" and uses "flags" to send things back to the Control Unit if the CPU. So, I know a fair amount about "How a computer works." But... it is all theoretical. I have memorized words and ideas like "ALU" and "Registry" and even RAM. But there is one thing that I do not understand and cannot seem to find anywhere on the internet. The verbs "write" and "store"...??? I know that a record cutter uses electrical current spread across metal plates with magnets that push a scoring tool into a soft "scratchable" medium to cut a long groove to make a record. Then a phonograph has a needle that that is likewise suspended between electrical currents with magnets that telegraph the grooves up a wire to replicate the sound through a horn (later a speaker). But as far as I know... RAM or a CPU's registries can have binary "words" somehow written to them for storage. I know it is happening at 3-4 billion times per second, but even if you slow it down to one time per minute... how does a CPU "write" 00110100 to RAM? There are no magnets in RAM like on a hard drive. RAM has no physical material that can be changed to represent a zero or a one... like... wax, or vinyl, or magnets. I don't even know who I can ask this to... so I'm asking here.

I need a story, characters, settings and someone who is willing to learn how to program and code in the basic level. I'm really just looking for people who are passionate about video games and who want to create one. I will later on open up my own video game company here in London (Yes I have the money for that). I also have publishers who will help in making our game get attention. But of course all this happens after the game is created. Any ideas? Anyone that lives in London? Or anyone who wants to join me online to create an amazing game? Thanks! Send me an email to JamesDuFont@programmer.net
