scp allows files to be copied to, from, or between different hosts. It uses ssh for data transfer and provides the same authentication and same level of security as ssh.

Amélioration du taux de délivrance des messages envoyés par un serveur Postfix

Si vous utilisez Postfix comme serveur de mails et que vous rencontrez un souci d’envoi de mails en nombre vers Orange.

Building a high-performance mail delivery system is one thing; building one that does not knock over other systems is a different story. Some mailers suffer from the thundering herd syndrome: they literally flood other systems with mail. Postfix tries to be a fast mailer and a good neighbor at the same time.

When writing more than a trivial script in bash, I often wonder how to make the code testable.

It is typically hard to write tests for bash code, due to the fact that it is low on functions that take a value and return a value, and high on functions that check and set some aspect in the environment, modify the file-system, invoke a program, etc. - functions that depend on the environment or have side effects. Thus the setup and test code become much more complicated than the code they test.

Rather inobstrusive carousels if you're required to use one

Almost all of the testing I've managed has proven that content delivered via carousels are missed by most users. Few interact with them and many comment that they look like adverts — we've witnessed the banner blindness concept in full effect.

In terms of space saving and content promotion, a lot of competing messages get delivered in a single position that can lead to focus being lost.

I'm quite certain that they are indeed a user-interface cliché borne out of their inclusion in wire-framing apps and being part of JavaScript frameworks.

So if they’re not effective, why do people use them? 2 reasons:

- Some people think they’re cool. But cool does not make you money – at least not this way.
- Different departments and managers want to get their message on the home page. Design by committee never fails to fail.

Frameworks are one of the hugest anti-patterns in software development. They're hard to learn. They limit your creativity. They increase your project's complexity and dependencies. They go out of business and get abandoned. You have to maintain and upgrade your code to match the latest framework versions for no good reason. You have to search for help and ask others for advice when you're stuck. And you probably only need a small percentage of features that the framework offers anyway. They just don't make much sense.

The Pandanet Internet Go Server is a great place for playing, watching, studying, and enjoying the game of Go on the internet. At any time, day or night, you can find hundreds of other players from all over the world and of all playing levels, from beginners to professionals. Whatever your ability, you can find opponents of similar skill to play with.

When the code has stopped at a breakpoint, you can examine its state in the variables pane of the debugger:

Don't make sense on non qwerty keyboards.
