+ - Planned Post-ACTA Repression In European Union: The Documents->

Submitted by petval
petval (2474520) writes "Rick Falkvinge, the Swedish Pirate Party MEP, discovered two interesting European Commission documentsProposal for a Revision of the Directive of Intellectual Property Rights and Notice and Takedown procedures that give a glimpse of the planned crackdown on online freedoms of speech post-ACTA. Falkvinge informs about some of the most blatant parts like references to eroding the common carrier status of the ISPs, fast-track lowcost civil procedures which should we read as "Fast-track, low-cost civil procedures: Civil procedures means “lawsuits against ordinary people”. Fast-track means “without delays caused by due process of law and exercising of rights”. Low-cost means “preferably in bulk”.. Continuing with other cases he also mentions some similarites with Transpacific Partnership Agreement (TPP).
His closing really sums it well: All in all, this is a completely horrible document that shows how the European Commission prepares to legislate post-ACTA. The proposals above have already entered the legislative process and will result in a real legislative proposal. We need to stay more vigilant than ever."

Security

+ - How do you visualize NTFS permissions across a large organization? 1

Submitted by Anonymous Coward
An anonymous reader writes "Our organization has a large network file storage system that uses NTFS. We have several thousand security groups in Active Directory. Our security process is split amongst various geographically separated help desks, each with various levels of authority. One group can set NTFS permissions, another can create groups, and a computer illiterate group orchestrates how groups are mapped to NTFS directories. I can't change this part, but I can make it work if our lower level of managers can see what groups have access to what folders.

I know that I can get Properties --> Security for each folder, but understanding the effects of putting Person 1 into Group X would be impossible to envision given the size of our network storage. I'm looking for a way to create a x-mas tree diagram of our file system, along with being able to light up the parts that are assigned access to a specific group. For example, it should be able to answer the question "What folders does Group X have Modify access to?"

I know that ICACLS does this, but it doesn't generate a visualized map. It also doesn't output structured data. If I could somehow expert all data into MS Access, I could probably create some kind of rudimentary GUI to navigate the folder structure.

I'd appreciate any advice."

It bothers me how Google undersupports Opera and how much effect it has on usability of their services. Plus is not working very well, for example the translation of link inserted into new stream entry does not work as in other browsers, Picasa is just lame in it, extensive usage of Javascript in Gmail can make the responses slow sometimes... Opera has to update the browser.js to make it work at least somehow.

However I love the way how can I customize Youtube with extensions or usersrcipts, how add blocking works (btw here's a generator for common ad source in many formats, one of them is Opera's urlfilter.ini here http://pgl.yoyo.org/as/ It completely different experience to surf the web with ads blocked or not.

Microsoft services like Technet and MSDN forums are also crippled in Opera but I know it is not Opera's fault.

Opera is unbeaten in working with lots of tabs - try working with 30+ tabs in other browsers and compare the speed and responsiveness of the user interface. Opera link is just great - there is simply no need for services like Readitlater on Instapaper if you have Opera Mini or Mobile on your phone / tablet, the bookmarks just sync there too. If it has problems it is most probably Flash error or situation where too many extensions and/or userscripts are processing the page.

I miss just better session manager preferably with syncing via Link.

Hi, you may want to have a look at this "Comparative test of Internet Anonymizers".
Quoting: We have been publishing and updating a comparative test of VPN services in German since 2009 which points out which VPN services log their users‘ IP addresses and which do not. Due to the current interest I am providing an English version of the short summary of the results (last updated: 02/06/2011).
