MX record

An MX record or Mail exchanger record is a type of resource record in the Domain Name System (DNS) specifying how Internet e-mail should be routed. MX records point to the servers to send an e-mail to, and which ones it should be sent to first, by priority.

Unidirectional Merge az SQL2005-ben

Amint arra sikerult rajonni a merge tipusu replikacional is be lehet allitani a Synchronization Direction-t, ami lehet:

-Bidirectional
-Download-only to Subscriber, allow Subscriber changes
-Download-only to Subscriber, prohibit Subscriber changes

Azzal volt bajom, hogy barmelyiket is valasztottam az visszaallt Bidirectional-ra mindenfele figyelmeztetes nelkul. Aztan vegul itt talaltam meg, hogy mitol van ez:

“to take advantage of this property (@subscriber_upload_options) the subscription must be marked as a ‘Client’ subscription and not the default of ‘Server’ subscription (see below). If you leave the default ‘Server’ option, the subscriber will always be created as bidirectional.”

LAMP

Hosts file

In computing, a hosts file, stored on the computer’s filesystem, is used to look up the Internet Protocol address of a device connected to a computer network. The hosts file describes a many-to-one mapping of device names to IP addresses. When accessing a device by name, the networking system will attempt to locate the name within the hosts file if it exists. Typically, this is used as a first means of locating the address of a system, before accessing the Internet domain name system. The reason for this is that the hosts file is stored on the computer itself and does not require any network access to be used, whereas DNS requires access to an external system, which is typically slower.

aspfaq.com: Why won’t my session variables stick?

Mi a 4-esbe futottunk bele, azaz: “If you are using IE 5.5 or IE 6.0, and your local server name has an underscore or other non-alphanumeric character (other than a dash) in the name, then cookies will not work correctly.”

K. Scott Allen: Impersonation and Application_Start in ASP.NET

Itt van az egesz, de a lenyeg:

…impersonation isn’t “on” during Application_Start… Application_Start is an odd event. It’s not really a request related event, but of course it won’t fire until the first event arrives. The ASP.NET runtime doesn’t start impersonation until it begins to process the request in earnest. This event fires just before impersonation begins, during a time when ASP.NET is laying out the cocktail napkins and setting up for the party.

CAPTCHA

CAPTCHA stands for “completely automated public Turing test to tell computers and humans apart.” What it means is, a program that can tell humans from machines using some type of generated test. A test most people can easily pass but a computer program cannot.

This article demonstrates how to create such an image and employ it within an ASP.NET web form.

itt van a teljes cikk.

What if you define the following methods in global.asax (yes, all of them):

• void Session_Start(object sender, EventArgs e)
• void Session_Start()
• void Session_OnStart(object sender, EventArgs e)
• void Session_OnStart()
• void Session_Start(object sender)

Having these five event handlers, which one(s) will be called?

It turns out all of them, except the last one, will be called, and in the same order as listed!

Karl Seguin: HttpHandlers – Learn Them. Use Them.

Itt van a teljes cikk.

Why use a handler?
First and foremost, HttpHandlers are far more reusable/portable than pages.
Secondly, the Page handler is relatively expensive… if you do that in a page you’ll end up raising a number of events (onInit, onLoad, onPreRender, onUnload, …) and make use of a number of ASP.NET features such as viewstate and postback. In most cases, the performance hit is negligible, but it nonetheless highlights that you’re using the page framework when you have no need to.

Why not to use HttpHandlers?
The biggest and very significant drawback of HttpHandlers is that they can only be used for extensions that are mapped to ASP.NET in IIS.

Types of Cloning: Deep and Shallow

In this article, I shall talk about an interesting aspect of .NET programming - Cloning objects.

A lenyeg:

We can classify two types of cloning based on “how much” is cloned: Deep and Shallow. A shallow clone is a new instance of the same type as the original object, which contains a copy of the value typed fields. But, if the field is a reference type, the reference is copied, not the referred object. Hence, the reference in the original object and the reference in the clone point to the same object. A deep clone of an object, on the other hand, contains a copy of everything directly or indirectly referenced by the object.

Ez a System.Xml.XmlDocument ImportNode-janak deep parameterekent azt jelenti, hogy a az adott node childnodejait is masoljuk vagy azokat nem.

\\\\ + c# + regexp >> \

Persze nyilvanvalo, mint ahogy itt le is van irva, de azert idemasolom nehogy megint elfelejtsem:

In literal C# strings, as well as in C++ and many other .NET languages, the backslash is an escape character. The literal string “\\” is a single backslash. In regular expressions, the backslash is also an escape character. The regular expression \\ matches a single backslash. This regular expression as a C# string, becomes “\\\\”. That’s right: 4 backslashes to match a single one.

Firefox 1.5-ben html height-ja fejbe vagja a body background-position-jet

A Firefox 1.5-ben ha a html height attributuma be van allitva, akkor az fejbe vagja a body background-position-jet. Itt van egy pelda html, amit ha IE-bol vagy vagy 1.5-nel regebbi Firefox-bol nezunk, akkor a kep az oldal jobb also sarkaban van es le kell tekernunk hozza. Ha ugyanezt Firefox 1.5-bol nezzuk, akkor a kep az oldal lathato reszenek a jobb also sarkaban van, akarhova is tekergetunk. (Ha a height attributumot 100%-rol 50%-ra valtoztatjuk, akkor meg a lathato resz jobb oldalanak kozepen.)

Mit ir errol a w3c:
"If a background image has been specified, the value of 'background-position' specifies its initial position." ... "A value pair of '100% 100%' places the lower right corner of the image in the lower right corner of the element." es "'bottom right' and 'right bottom' mean the same as '100% 100%'" Az element pedig itt a body. Ebbol nekem ugy tunik hogy az 1.5-os viselkedik hibasan es nem a tobbiek.

Tehat a pelda:

<head>
<style type="text/css">
html {height: 100%}
body {
background-image: url(http://www.google.com/images/logo.gif);
background-position: bottom right;

Paul Graham: Never make users register

Itt van a teljes iras, de a lenyeg:

At Y Combinator we advise all the startups we fund never to lord it over users. Never make users register, unless you need to in order to store something for them. If you do make users register, never make them wait for a confirmation link in an email; in fact, don't even ask for their email address unless you need it for some reason. Don't ask them any unnecessary questions. Never send them email unless they explicitly ask for it. Never frame pages you link to, or open them in new windows. If you have a free version and a pay version, don't make the free version too restricted. And if you find yourself asking "should we allow users to do x?" just answer "yes" whenever you
