RSS-Feed Mediawiki extension

  • original by mutante 25.03.2005
  • extended by Duesentrieb 30.04.2005
  • extended by Rdb78 07.07.2005
  • extended by Mafs 10.07.2005, 24.07.2005
  • extended by User:Arcy 07.09.2005
  • Updated for MediaWiki 1.6 by User:piku 13.06.2006
  • Update for Wikicode output, by User:cogdog 14.jul.2006

Requires:

Installation:

  • put this file (rss.php) into the extension directory of your mediawiki installation
  • add the following to the end of LocalSettings.php: include("extensions/rss.php");
  • make sure magpie can be found by PHP.

Usage:

Use one section between <rss>-tags for each feed. The rss section may contain parameters separated by a pipe ("|"), just like links and templates. These parameters are supported:

charset = ... The charset used by the feed. iconv is used to convert this.
short Do not show the description text for each news item.
max = x Shows x most recent headlines.
highlight = term1 term2 The terms separated by a space are highlighted.
filter = term1 term2 Show only rss items containing at least one of the terms.
reverse display the rss items in reverse order.
title = x display an alternative title instead of chanel name.
title = none dont display any title.

Example:

<rss>http://slashdot.org/slashdot.rss|charset=UTF-8|short|max=5</rss>

GAO Denied Access To Webb Telescope Workers By Northrop Grumman

Thu, 26 Mar 2015 23:44:00

schwit1 writes In a report as well as at House hearings today the GAO reported that Northrop Grumman has denied them one-on-one access to workers building the James Webb Space Telescope. "The interviews, part of a running series of GAO audits of the NASA flagship observatory, which is billions of dollars overbudget and years behind schedule, were intended to identify potential future trouble spots, according to a GAO official. But Northrop Grumman Aerospace, which along with NASA says the $9 billion project is back on track, cited concerns that the employees, 30 in all, would be intimidated by the process." To give Northrop Grumman the benefit of the doubt, these interviews were a somewhat unusual request. Then again, if all was well why would they resist? Note too that the quote above says the cost of the telescope project is now $9 billion. If the project was "back on track" as the agency and Northrop Grumman claim, then why has the budget suddenly increased by another billion?

PayPal To Pay $7.7 Million For Sanctions Violations

Thu, 26 Mar 2015 23:03:00

jfruh writes PayPal may not be a bank, but it's still legally required to follow regulations on transferring money — but the company has admitted to a number of violations, including allowing transfers to an individual specifically sanctioned by the U.S. State Department for helping proliferate nuclear weapons. From Ars: "On Wednesday afternoon, PayPal reached a settlement with the US Treasury Department, agreeing that it would pay $7.7 million for allegedly processing payments to people in countries under sanction as well as to a man the US has listed as involved in the nuclear weapons black market. The company neither confirmed nor denied the allegations, but it voluntarily handed over its transaction data to the US Department of Treasury’s Office of Foreign Assets Control (OFAC)."

Australia Passes Mandatory Data Retention Law

Thu, 26 Mar 2015 22:20:00

Bismillah writes Opposition from the Green Party and independent members of parliament wasn't enough to stop the ruling conservative Liberal-National coalition from passing Australia's new law that will force telcos and ISPs to store customer metadata for at least two years. Journalists' metadata is not exempted from the retention law, but requires a warrant to access. The metadata of everyone else can be accessed by unspecified government agencies without a warrant however.

Micron and Intel Announce 3D NAND Flash Co-Development To Push SSDs Past 10TB

Thu, 26 Mar 2015 21:38:00

MojoKid writes Both Micron and Intel noted in a release today that traditional planar NAND flash memory is reaching a dead-end, and as such, have been working together on 3D memory technology that could open the floodgates for high densities and faster speeds. Not all 3D memory is alike, however. This joint development effort resulted in a "floating gate cell" being used, something not uncommon for standard flash, but a first for 3D. Ultimately, this 3D NAND is composed of flash cells stacked 32 high, resulting in 256Gb MLC and 384Gb TLC die that fit inside of a standard package. That gives us 48GB per die, and up to 750GB in a single package. Other benefits include faster performance, reduced cost, and technologies that help extend the life of the memory.

Generate Memorizable Passphrases That Even the NSA Can't Guess

Thu, 26 Mar 2015 20:59:00

HughPickens.com writes Micah Lee writes at The Intercept that coming up with a good passphrase by just thinking of one is incredibly hard, and if your adversary really is capable of one trillion guesses per second, you'll probably do a bad job of it. It turns out humans are a species of patterns, and they are incapable of doing anything in a truly random fashion. But there is a method for generating passphrases that are both impossible for even the most powerful attackers to guess, yet very possible for humans to memorize. First, grab a copy of the Diceware word list, which contains 7,776 English words — 37 pages for those of you printing at home. You'll notice that next to each word is a five-digit number, with each digit being between 1 and 6. Now grab some six-sided dice (yes, actual real physical dice), and roll them several times, writing down the numbers that you get. You'll need a total of five dice rolls to come up with each word in your passphrase. Using Diceware, you end up with passphrases that look like "cap liz donna demon self", "bang vivo thread duct knob train", and "brig alert rope welsh foss rang orb". If you want a stronger passphrase you can use more words; if a weaker passphrase is ok for your purpose you can use less words. If you choose two words for your passphrase, there are 60,466,176 different potential passphrases. A five-word passphrase would be cracked in just under six months and a six-word passphrase would take 3,505 years, on average, at a trillion guesses a second. After you've generated your passphrase, the next step is to commit it to memory.You should write your new passphrase down on a piece of paper and carry it with you for as long as you need. Each time you need to type it, try typing it from memory first, but look at the paper if you need to. Assuming you type it a couple times a day, it shouldn't take more than two or three days before you no longer need the paper, at which point you should destroy it. "Simple, random passphrases, in other words, are just as good at protecting the next whistleblowing spy as they are at securing your laptop," concludes Lee. "It's a shame that we live in a world where ordinary citizens need that level of protection, but as long as we do, the Diceware system makes it possible to get CIA-level protection without going through black ops training."
