Chapter 6. Virtual networking:Configuring port forwarding with NAT on Vitualbox
VBoxManage modifyvm "VM name" --natpf1 "guestssh,tcp,,2222,,22" With the above example, all TCP traffic arriving on port 2222 on any host interface will be forwarded to port 22 in the guest. The protocol name tcp is a mandatory attribute defining which protocol should be used for forwarding (udp could also be used). The name guestssh is purely descriptive and will be auto-generated if omitted. The number after --natpf denotes the network card, like in other parts of VBoxManage. To remove this forwarding rule again, use the following command: VBoxManage modifyvm "VM name" --natpf1 delete "guestssh" If for some reason the guest uses a static assigned IP address not leased from the built-in DHCP server, it is required to specify the guest IP when registering the forwarding rule: VBoxManage modifyvm "VM name" --natpf1 "guestssh,tcp,,2222,,22" This example is identical to the previous one, except that the NAT engine is being told that the guest can be found at the a

Networx: Bandwidth monitor, bandwidth speed test, bandwidth and traffic monitoring tool for Windows
NetWorx is a simple and free, yet powerful tool that helps you objectively evaluate your bandwidth situation. You can use it to collect bandwidth usage data and measure the speed of your Internet or any other network connection. NetWorx can help you identify possible sources of network problems, ensure that you do not exceed the bandwidth limits specified by your ISP, or track down suspicious network activity characteristic of Trojan horses and hacker attacks. The program allows you to monitor all your network connections or a specific network connection (such as Ethernet or PPP) only. The software also features a system of highly customizable visual and sound alerts. You can set it up to alert you when the network connection is down or when some suspicious activity, such as unusually heavy data flow, occurs. It can also automatically disconnect all dialup connections and shut down the system. The incoming and outgoing traffic is represented on a line chart and logged to a file, so t

Google's Python Class - Google Code
this is a free class for people with a little bit of programming experience who want to learn Python. The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. The first exercises work on basic Python concepts like strings and lists, building up to the later exercises which are full programs dealing with text files, processes, and http connections. The class is geared for people who have a little bit of programming experience in some language, enough to know what a "variable" or "if statement" is. Beyond that, you do not need to be an expert programmer to use this material.

Metacritic: Best-Reviewed Movies
The following list contains the 200 highest-scoring films in Metacritic's database with a minimum of seven reviews. Since our database consists mainly of more recent releases (virtually every film since the beginning of 1999, and selected films from prior years) most of the films on this list will be from that period. Periodically, we add additional films from the 1990's and prior decades to our database, and these releases will find their way onto this list as appropriate. Note that any movies labeled "re-release" are not included in the high score list since their scores are based on reviews at the time of the re-release rather than at the time of the original release.

Exceptionally difficult Sudokus (Hardest Sudokus) - Wikipedia, the free encyclopedia
Some of the sudoku puzzles can only be solved using logic that is too complex for human solvers. Most would describe them as unsolvable after exhausting their arsenal of sudoku solving techniques and would proceed to a trial and error path to reach a solution. It was no surprise that computer programmers were interested in this subject, trying to generate even more difficult puzzles or even trying to find new ways to logically solve and rate them. Rating puzzles that are beyond human capabilities proved to be difficult as different points of view regarding what could be considered a yardstick for measuring difficulty resulted in heterogeneous opinions on which puzzle is the hardest of them all. Several active discussions on this issue took place on a number of popular sudoku forums since 2005.[9][10][11] Several openly accessible solver programs became popular between users for the purpose of rating and generating such puzzles.

The world's hardest Sudoku puzzle : Zonked Yak
It's times like these that the internet makes me most happy. When respectable online publications publish entertaining and interesting stories about the world's hardest Sudoku puzzle, you'd at least expect them to give you a link to it, or a picture of it. Oh, yes, you guessed it. They don't. But I couldn't find it anywhere! So I undustriously hunted, and eventually found the secret formula hidden away in an ASCII-like tomb of Sudoku knowledge. And now, for the first time in propper format, and luckily without any further ado (read the real reporter's background here), I give you AL Escargot, the hardest rated Sudoku puzzle to date:

MySQL :: Re: Problem when I rename the slave and master servers?
The command RESET SLAVE will delete all the slave files that keep track of what log file on what server and other information. You will of course need to have the info in your my.cnf unless you do a CHANGE MASTER TO command after that. I believe you should be able to do RESET SLAVE and then START SLAVE right after that to work.

Programming language popularity based on Usenet postings
This page measures programming language popularity by the number of postings in Usenet newsgroups about the language (restricted to groups in the comp.lang hierarchy; I have collected some data for the microsoft.public.dotnet.languages hierarchy, but our server expires messages from this hierarchy faster, so one would have to scale for that to get comparable results). This has the advantage that it is easy to measure. Other, harder to measure, but probably more useful metrics would be the number of different postings in groups for the same language (i.e., count cross-postings between groups for the same language only once), the number of different posters in groups for the same language, or (not measurable) the number of readers of a group for a programming language.
