Git Magic

Git is a version control Swiss army knife. A reliable versatile multipurpose revision control tool whose extraordinary flexibility makes it tricky to learn, let alone master. I'm recording what I've figured out so far in these pages, because I initially had difficulty understanding the Git user manual.

As Arthur C. Clarke observed, any sufficiently advanced technology is indistinguishable from magic. This is a great way to approach Git: newbies can ignore its inner workings and view Git as a gizmo that can amaze friends and infuriate enemies with its wondrous abilities.

Rather than go into details, we provide rough instructions for particular effects. After repeated use, gradually you will understand how each trick works, and how to tailor the recipes for your needs.

The Art of Engineering

Thank goodness some inventors specialize in ways to make our lives a little easier, especially around the house. Borrowing a page from Buckminster Fuller, one of his heroes, James Dyson ‘sees what needs to be done and just does it.’

In a show-and-tell format, Dyson offers a compendium of his labor-saving, ingenious designs, with side bars on business and engineering details. While Dyson has come up with washing machines, wheelbarrows and boats, the lion’s share of his presentation concerns his Dual Cyclone vacuum cleaner, which tidily eliminates several nasty aspects of ordinary vacuum cleaners: loss of suction, bag-changing and the emission of dirty air. “As a child, I remembered the screaming noise, smelling stale dust and picking things up in my hands the vacuum wouldn’t suck up.”

Lock-Free Code: A False Sense of Security

Clip Source: www.ddj.com

Given that lock-based synchronization has serious problems [1], it can be tempting to think lock-free code must be the answer. Sometimes that is true. In particular, it's useful to have libraries provide hash tables and other handy types whose implementations are internally synchronized using lock-free techniques, such as Java's ConcurrentHashMap, so that we can use those types safely from multiple threads without external synchronization and without having to understand the subtle lock-free implementation details.

But replacing locks wholesale by writing your own lock-free code is not the answer. Lock-free code has two major drawbacks. First, it's not broadly useful for solving typical problems—lots of basic data structures, even doubly linked lists, still have no known lock-free implementations. Coming up with a new or improved lock-free data structure will still earn you at least a published paper in a refereed journal, and sometimes a degree.

Using GnuPG with PHP

Clip Source: devzone.zend.com

It's this fascination with gadgets and security that first brought GnuPG to my attention a few years ago. GnuPG is open-source software that makes it possible to encrypt your email and other messages so that they can only be read by the intended recipient (not unlike Jim Phelps and his briefing book). Unlike cleartext messages, which are unprotected and can be read by anyone who intercepts them, GnuPG-encrypted messages are "locked" through cryptographic techniques and may be viewed only by a person with the correct "key"; everyone else will merely see gibberish. In today's day and age, when hacking and phishing is common, such encryption plays an important role in protecting sensitive data like user names, passwords or credit-card information.

Beginning Game Programming

Last Updated 7/27/08

These tutorials were made to help programmers start out in game programming. I tried to keep them as simple and to the point as possible. They are a perpetual work in progress, and will be improved over time.

They use C++ as the programming language because it is considered the game industry's standard. SDL is used as the API because it is cross platform, and relatively easy to use.

URL rewriting can be one of the best and quickest ways to improve the usability and search friendliness of your site. It can also be the source of near-unending misery and suffering. Definitely worth playing carefully with it - lots of testing is recommended. With great power comes great responsibility, and all that.

There are several other guides on the web already, that may suit your needs better than this one.

Apache URL Rewriting Guide - The best guide around

Before reading on, you may find it helpful to have the mod_rewrite cheat sheet and/or the regular expressions cheat sheet handy. A basic grasp of the concept of regular expressions would also be very helpful.

Regardless of whether you're running a single MySQL server or a cluster of multiple servers, one thing you are always interested in is squeezing the maximum performance out of your system. MySQL's developers were well aware of this, and so they provided a fairly comprehensive list of performance variables that you can monitor in real time to check the health and performance of your MySQL server.

These variables are accessible via the SHOW STATUS command. In Table A, we've listed 10 of the most important performance variables you should monitor when using MySQL, and we explain which particular attribute each of them reflects.

Automate a Remote Login Using SSH-Agent

Sat, 02 Aug 2008 05:18:32 GMT

clipped by: prostoalex

Clip Source: www.webmonkey.com

When it comes to remote logins, SSH is a wonderful tool. Not only is it secure, it supports public/private key logins. Depending on public and private keys mean even if someone gets your password, without your private key it won't do them any good (and vice versa).

However, if you've ever wanted to automate a remote login or to copy some files for backup purposes, you know that it's not easy to do an SSH login without a password.

The easiest option would be creating a key pair without a password. Easy, yes. But this is one of the worst ideas you could implement. It effectively destroys one of the primary benefits of using SSH since taking control of the local machine can potentially give an attacker instant and easy access to your remote machine as well -- two for the price of one.

The far better option is to use ssh-agent, which is far more secure and doesn't require you to abandon the added protection of using a password with your SSH keys.

Setting up a LAMP server is a common task for systems administrators, and FreeBSD is one of the most reliable and stable operating systems available. You can swap out the L in LAMP with F for FreeBSD to build a fast and reliable Web server.

In this article I assume FreeBSD is already installed. If not, make sure you download the latest stable production version of FreeBSD and run the installer. I recommend choosing the MINIMUM option at the installer screen to quickly install only the most basic and necessary things.

Reliable DNS Forgery in 2008 - Kaminsky’s Discovery

1.
Pretend for the moment that you know only the basic function of DNS — that it translates WWW.VICTIM.COM into 1.2.3.4. The code that does this is called a resolver. Each time the resolver contacts the DNS to translate names to addresses, it creates a packet called a query. The exchange of packets is called a transaction. Since the number of packets flying about on the internet requires scientific notation to express, you can imagine there has to be some way of not mixing them up.

Bob goes to to a deli, to get a sandwich. Bob walks up to the counter, takes a pointy ticket from a round red dispenser. The ticket has a number on it. This will be Bob’s unique identifier for his sandwich acquisition transaction. Note that the number will probably be used twice — once when he is called to the counter to place his order and again when he’s called back to get his sandwich. If you’re wondering, Bob likes ham on rye with no onions.

Anatomy of the Linux kernel

While Linux is arguably the most popular open source operating system, its history is actually quite short considering the timeline of operating systems. In the early days of computing, programmers developed on the bare hardware in the hardware's language. The lack of an operating system meant that only one application (and one user) could use the large and expensive device at a time. Early operating systems were developed in the 1950s to provide a simpler development experience. Examples include the General Motors Operating System (GMOS) developed for the IBM 701 and the FORTRAN Monitor System (FMS) developed by North American Aviation for the IBM 709.

Build a custom search engine for your Web site with Sphinx

Wed, 16 Apr 2008 05:13:37 GMT

clipped by: prostoalex

Clip Source: www.ibm.com

To provide a custom search feature for your site, you must have a data source and the ability to search that source. For a Web application, the data source is commonly a relational database, which has some forms of search built in. (Equality is a simple search operator, as is the SQL operator LIKE.) Yet, some searches may be more specialized than the database can perform, or a search may be so complicated that the inherent SQL JOINs are simply too slow.

As an alternative, consider Sphinx, which is an open source and free (as in speech and beer) search engine designed to search text extremely quickly. For instance, on a live database of nearly 300,000 rows of five indexed columns, where each column contains about 15 words, Sphinx can yield a result for an "any of these words" search in 1/100th of a second (on a 2-GHz AMD Opteron processor with 1 GB of RAM running Debian Linux® Sarge).
