Главное, что я понял
Главное, что я понял — это то, что в человеке заложено огромное количество сил и энергии. Если мы несем ответственность за свою жизнь, то мы эти силы направляем на вполне позитивные, правильные вещи — бизнес, карьера, построение качественной личной жизни. Если же мы предпочитаем пассивное времяпровождение — то нам остается интернет, ТВ, пиво и прочие прелести потребительского образа недожизни. Каждому — свое.
Но силы есть у всех.

t-sql unit testing
Here is simple t-sql unit testing approach by writing sql script that will do all testing work.
I like this solution the most because it's very flexible and doesn't require additional installations on sql server.
Also I think the best way to write sql unit tests is to make them independent from data.And validate logic but not data.
Such unit tests can be run on development or qa and even production environment.
Also there are another sql unit test frameworks .

use of hashtable in javascript
here is an example of usage of hashtable in javascript.For example I want to asociate specific buttonId
with specific grid Id I could create following hashtable:
Then I could use it in code :
with specific grid Id I could create following hashtable:
var GridsButtons = {
'AGroupsListGrid' :'DelA',

asp.net mvc ajax post from javascript
Following example demonstrate how to submit form in asp.net MVC for strict type view based on model:
(view has this instruction oin top:
@model MyModel
):
javascript part:
on server side model variable will have updated with all values submitted in form and will have following parameters:
(view has this instruction oin top:
@model MyModel
):
javascript part:
<script type="text/javascript">
$(document).ready(function() {
$("#GoButton").click(function() {
var frm = $(this).closest('form');
var params = frm.serialize();
$.ajax({
type: 'POST',
url: '@Url.ApplicationAction("MyPostAction", "myController")',
data: params,
cache: false,
success: function (data) {
alert('Completed');
},
error: function (xhr, data, message) {
//console.log(data + ": " + message);
},
dataType: "json"
});
return false;
});
});
</script>
on server side model variable will have updated with all values submitted in form and will have following parameters:
[HttpPost]
public ActionResult MyPostAction(MyModel model)
{
return Json("Ok");
}

Уроки
Урок 1 (он же главный): Найдите наикратчайший из способов удовлетворить потребность и не напрягайте пользователей деталями.
Нам через день предлагают добавить ту или иную фишку. Первый вопрос которым мы задаемся — а какому проценту наших пользователей это понадобиться. Если меньше 5% — мы этого делать не будем.
Урок 2 (вообще-то продолжение первого): ненужная большинству функциональность вредна поскольку усложняет понимание.
Вот как мы расправились с некоторыми из сложностей:
- Программа должна была работать с несколькими проектами/работами. Однако для большинства достаточно создать только один проект выбрав несколько баз для бэкапа. Мы сделали так, что программа сама открывает тот же проект, что и в прошлый раз и соединяется с тем же SQL сервером — так что большинство даже и не задумывается, что можно работать с несколькими проектами.
- SQL Connection String — до сих пор самая сложная часть для пользователя. При первом запуске мы, не спрашивая пользователя, перебираем самые распространенные Connection String, так что, открыв программу, большинство пользователей уже подключились к серверу и видят список своих баз данных.
- Посылка писем — чтобы не напрягать пользователей с настройкой SMTP мы по умолчанию посылаем письма через веб-сервис на своем сервере. Для бесплатных пользователей фишка бесплатна на неделю, а потом можно либо купить платную версию либо пользоваться своим Gmail или другим SMTP сервером.
- Расписание — большинству требуется Full Backup один раз в день. Что и можно сделать на основной форме. Для более продвинутых все настройки спрятаны за кнопкой Settings.
Деньги
Поработав немного, мы сделали первую версию программки. Далее мы поставили ее во все shareware-сайты и оставили комментарии на форумах по этой теме. Понемногу пошли клиенты. Через два месяца после выпуска нас заметила одна большая компания, продукт которой был основан на SQL и его пользователи с небольшими техническими знаниями были сами ответственны за бэкап. Для них мы подходили идеально и они послали всех своих пользователей к нам. Кроме этого они даже взяли на себя заботу по тех поддержке. Деньги потекли рекой.
Основная версия (Standard) стоит сейчас $59. Для тех компаний для которых это не деньги — у нас есть Professional с добавкой AES encryption за $69. Для экономных — Lite (максимум 5 баз данных) за $29. С год назад я прочитал какую-то статью о том, что цены на странице Prices нужно подавать от больших к малым дабы пользователю, испуганному первыми большими цифрами, цифра в середине показалась относительно скромной. Мы подумали: что бы такого выпустить дорогого чтобы пугать пользователей? Так родилась идея Lifetime-версии за $199 (сейчас $149) с бесплатными пожизненными обновлениями. И мы очень удивились когда ее стали бодро покупать!
Потом товарищ подкинул другую идею, которая принесла тысячи долларов. В добавок к продуктам мы продаем за небольшие деньги еще и Extended Support (тем, кто его купил — особое внимание при поддержке) и бесплатное обновление на 1 год (по умолчанию — 1 месяц). Дополнительные усилия близки к 0, а деньги понемногу капают…
Урок 3 — дайте пользователю заплатить столько, сколько он хочет и может.
Пиратство и жадность
С первых дней существования мы решили тратить только минимум времени на борьбу с пиратством. В программе зашит алгоритм на проверку лицензионного ключа который несложно взломать. Идея такова: если человек запускает keygen для взлома — он вряд ли заплатил бы за программу без этого. А так — будет пользоваться и, возможно, когда остепенится, тогда и почувствует потребность заплатить.
Многие устанавливают ключик на несколько машин — мы просто посылаем вежливые письма с напоминанием, что это неправильно. Компании в цивилизованных странах стараются договоренности соблюдать и покупают недостающие лицензии. С менее цивилизованными мы могли бы справиться добавив активацию, но это усложнило бы жизнь для большинства честных клиентов. И опять же: нами пользуются и это уже хорошо.
Урок 4 — концентрируйтесь на продукте, а не на защите. Пират сегодня — клиент завтра.
Большинству вполне хватает бесплатной версии в которой можно делать то же самое, что и в стандартной, только с ограничением в две базы данных. Благодарный народ даже пожертвования предлагает. Да мы и рады: когда потребности вырастут, тогда и заплатят, а заодно боремся с бесплатными самоделками.
Недавно мы добавили бэкапы в Amazon S3, Google Drive и Dropbox. Сначала было желание брать дополнительные деньги. Но решили не напрягать пользователей и просто добавить к существующим версиям. Будет больше пользователей — значит и доходы вырастут.
Урок 5 — довольные клиенты важнее сиюминутного наполнения карманов.
