Bryan Quigley: Converting Dad to Ubuntu - Investing Site

Mon, 08/25/2008 - 21:03
My longest standing issue for converting my Dad to Ubuntu was one investing website that uses an ActiveX control. They do have a way for Firefox users though, but it doesn't work on Linux or with wine.

I eventually started trying to get IE4Linux (which uses wine) to get it to work. And it worked fine, except for the flash ads, which make the page unbearable to look at (the entire page flickers when any movement is registered in any flash window).

Now I couldn't just get rid of flash, because they used flash for videos on the site. And I don't have any interest in learning to block things in IE.

The eventual solution: IE4Linux with Moblock (Peerguardian for Linux) to block the IP addresses of Ad servers, so no more annoying flash ads.

It is available in 1080i on digital broadcast TV. My family has actually gone back to broadcast to get it.

What channels can you get (in Cherry Hill, with a really bad antenna)?
Note: Channels 6.* came back to not being flaky and some of the higher numbers are flaky again.

Oh, and Hello Planet Ubuntu!

Edward Corrado: Antipiracy Campaign Exasperates Colleges

Fri, 08/15/2008 - 09:19

The Chronicle of Higher Education has an interesting article about Colleges and Universities who have “bent over backward to help the Recording Industry Association of America curb illegal file sharing on his campus” before by passing on “prelitigation settlement letters” and gave over other information in the past. These colleges have found that the RIAA is just asking for more and more information that is overburdening already stretched thin staff. Now that they have realized the amount of effort and staff time they have been spending on this, and have concerns that doing some of these things may actually violate Family Educational Rights and Privacy Act (FERPA), they are finding that past compliance is causing them problems. It is hard to convince a judge that responding to these requests now are an “undo burden” if you have followed through in the past. I guess what surprises me a little about this is how the Universities in the article didn’t consider this early on, before responding to the first request. It is not really surprising that your past actions will be held against you in these types of cases. Once you start bowing down to the RIAA, or any other organization doing this witch hunts, it is hard to break away. Maybe these colleges should have been a little bit more concerned about violating FERPA and having the wrong students accused in the first place. I guess that is the lesson here. If you are ever put in to the situation these colleges were put into first, you need to make sure you think through all of the consequences of how you respond the first time as once you make a decision to comply, it will be very hard to undo that choice.

J.D. Abolins: Some notes on the DNS vulnerability matter...

Thu, 08/14/2008 - 23:55
There has been much tech chatter about Dan Kaminsky's reporting about a major DNS vulnerability. I am not going to rehash all the reporting here. But I do want to mention a few odds and ends observations.
  • Dan Kaminsky has some information about the DNS vulnerability, his Defcon presentation, etc. at http://www.doxpara.com/ (IP address:157.22.245.20). The site also has a DNS Checker to see if you Internet connection is particularly vulnerable to DNS mischief. Take a look at his post with "Summaries".
  • Steve Friedl has "An Illustrated Guide to the Kaminsky DNS Vulnerability". Nice!
  • It can be prudent to catalogue the IP addresses of crucial site you use. One way is to use nslookup to find the IP addresses.
  • BUT connecting to a server using its IP address is not a 100% guarantee of protection from DNS mischief. If, for example, the server pulls information from other servers using DNS information, the DNS vulnerability could affect this. Mashups could be particularly susceptible to this.
  • If you're using Firefox and accessing a site using its IP address instead of the usual URL, you may run into a Secure Connection Failed warning saying something about an "invalid security certificate". This doesn't necessarily mean you've reached a bogus site. See FireFox's support for more information on this.

J.D. Abolins

Clarification NoteAdded 19 Aug 2008:
The mention of noting IP addresses of crucial sites is not the answer to the DNS vulnerability. It is simply mentioned as a helpful thing in general if you're dealing with certain crucial servers. For actual advice on dealing with the DNS vulnerability, follow the links to Dan Kaminisky's site.

Modification on 24 Aug 2008: I applied strikeouts to the observations that are confusing. Although I have a sound basis for those observations, they do look like the main advice given for the DNS vulnerability, rather than peripherial observations for using known IP address as a help for DNS problems in general.  Many aoplogies for the confusion.

Edward Corrado: Bethel Motor Speedway Opening Saturday, August 2

Sun, 07/27/2008 - 14:40

Bethel Motor Speedway is a 1/4 mile paved oval track in White Lake, NY built in 1959. The track was previously known as White Lake Speedway, White Lake Raceway, Catskill Mountain Speedway, Kauneonga Speedway, and Sullivan County Speedway. In the past 10 or so years, the track has been closed and opened a number of times. After the 2006 season, the track closed and was eventually sold to new owners. The new ownership team plans to race every Saturday night n august and September with the first race being thi cming Saturday, August 2. I already have plans for the next few Saturdays, but I hope the track does well enough to run regularly again and I do plan on attending at least once this year.

All tests were done with an Ubuntu LiveCD on the same machine for both 7.10 and 8.04.1. A network card may have changed between 7.10 and 8.04.1. Applications used were Firefox, OpenOffice.org Writer, Rhythmbox, Totem and Gimp. All values copied out of Gnome System Monitor.

J.D. Abolins: I'll be speaking in Southern NJ on 1 Aug 2008

Fri, 07/25/2008 - 00:07
"Hacking & the Law: What Are the Legal Considerations of Tinkering with Software & Hardware?"
Presentation for the Cherry Hill Linux Users Group (CHLUG)
Friday 1 Aug 2008 from 7pm to 9pm
in the Multicultural Room of The Cherry Hill Public Library.
1100 Kings Highway N., Cherry Hill, NJ. [Directions]
The meeting is open to the public.

UPDATE 24 Aug 2008: The slides from the presentation (including updates) are now online. [pdf]

When I offered to speak at a CHLUG meeting, I asked what information security topics they wanted covered. The answer was "Hacking & the Law". Interesting, but it is too vast a topic to cover in 45 minutes. I asked what they meant by "hacking". The CHLUG members explained they were interested in "hacking" as it pertains to tinkering with software and hardware. Since this is a Linux users group, the emphasis would be upon free & open source (F/OSS) concepts. Excellent!

Some of the things I'll cover include
  • Quick overview of concepts such as copyrights, fair use, and patents.
  • Overview of F/OSS licensing approaches such as GPL ones.
  • Can F/OSS licensing provisions be enforced by law?
  • Hardware tinkering issues such as "Tivoization" where a system incorprates F/OSS but the hardware is designed to prevent modification of the code.
  • Examination of the issues raised by things such as the DMCA anti-circumvention provisions.
  • Issues that can arise when publicising info about our tinkering.
  • Suggestions for dealing with these issues.
(NOTE: I am not a lawyer and this general presentation is not a substitute for competent legal counsel.)

J.D. Abolins: Last HOPE photos, videos, etc.; Hacker Scene Anthem

Wed, 07/23/2008 - 09:26
At the HACDC Hackerspace area.
I'm posting photos and, eventually, videos at my Flcikr collection.
(You can see other Flickr images with the tags "Last HOPE" and "hacker" here.)

A Hacker Scene Anthem?
(Eine Hymne für die Hackerszene?)A the closing of the Last HOPE conference, the funeral them broke in joyfulness when it was announced that this 2008 conference is not the final one but the last one attended so far. Then, a fellow from Austria added to the happy moment by proposing a hacker anthem: "Surfen Multimedia" done by the Eurocats in 1998. [mp3 link]

English translation of the lyrics:

Suring surfing through the world with multimedia
Suring surfing, day and night
on the data highway

Come join me on the internet tonight
I'm already waiting for you
Dude, be a user, go online
You'll meet me in the email

And should you lack some megabytes
You’ll find them here with me
Be it interface or cyberspace
I'll gladly share with you

With bits and bytes
With mouse and click
We are going on a tour
In the World Wide Web
We'll follow each new hint today Just the song to listen while "surfen auf der Daten-Autobahn". Sorta like what ABBA might have done had they gotten interested in the Internet.

Edward Corrado: Tech Therapy Podcast on “Setting Professors Right on Rights”

Tue, 07/22/2008 - 08:11

Over the past few days, I’ve been listening to Tech Therapy. Tech Therapy is a series of podcasts in which “Scott Carlson, a Chronicle reporter, and Warren Arbogast, a technology consultant who works with colleges, talk about the headaches, anxieties, and general problems you might be having with technology on your college campus.” In through the archives, I listened to an interview with William Shell, director of academic technology and computing services at Eastern Michigan University, who asks: “How can a university make faculty members aware of copyright law?” Obvious, copyright is a big issue for libraries, and I really like that the conversation brought in the idea that the IT department partner with librarians who are familiar with, and interested in, copyright and fair use issues. They also brought in some other ideas about how to educate faculty about the issues involved without being seen as “the copyright police.” All of the Tech Therapy podcasts I listened to are interesting, but this one stood out for the librarian in me since they said things like “your best friends [on this issue] are in the library.” Probably not a lot of new information with people who deal with this, but still it was nice to see these non-librarian techies advocating for the librarians on this issue.

Edward Corrado: Well-presented negative results

Mon, 07/21/2008 - 09:13

I read with interest the call for papers for the 3rd IEEE/ACM International Conference on Information and Communication Technologies and Development (ICTD2009). What caught my eye was the sentence of the conference focus which reads “Well-presented negative results from which generalizable conclusions can be drawn are also sought.” I’d like to see more reporting of well presented negative results at library-related conferences. Sometimes we here about negative results on e-mail lists when some asks the question “Has any tried this?” but very rarely do we have sessions that report on things that didn’t work out at conferences or read them in articles. This leads to different people try their same thing and also failing whereas if the negative results were public they could either decide to go in a different direction, or the can look at what didn’t work in the previous project and figure out a way to modify the approach so it will work.

Edward Corrado: Library Statistics

Sun, 07/20/2008 - 09:16

In a number of different settings, both at work and while talking to librarians from other institutions, the subject of library statistics have come up. While all types of library statistics are always an item for discussion, in particular statistics about the size of various library collections have come up recently. While counts of traditional print materials are troublesome enough, counts of electronic resources are even more of an issue. There are just so many variables that make comparing these counts from library to library very difficult. One library may count a collection of databases as one database, while another may count each individual database separately. This is not to mention that the amount and quality of items in different databases can vary greatly.

One thing that I’ve been thinking about recently with respect to library statistics lately is what do we count that is available electronically? Specifically, should we count things that we provide access to that are freely available on the Web. For instance, if we provide a record for the Code4Lib Journal, or the dLIST (Digital Library of Information Science of Technology) should we count them as a serial or database holding respectively. How about if we add MARC records for freely available government documents from a vendor such as MARCIVE to our catalog? Does each record count as a government document although we didn’t purchase or physically possess the document. I’m not sure how many libraries count these items, but I know from talking to librarians many libraries only count items they directly pay for. I don’t think this is the correct approach. I think, especially with the high quality of many Open Access journals and other documents, the should be counted. If a librarian has taken the time and effort to evaluate a resource or collection of resources and to add it to the collection, I think it should count. Academic libraries no longer are just about physical collections of information, they are about providing access to quality information. Thus, if the library takes even minimal actions to provide access to a resource, it should be included in these counts (flawed as the are).

Bryan Quigley: Year of the Linux Desktop Part 4

Sat, 07/19/2008 - 21:44
Apparently I wasn't the only one to notice that Linux had a good marketshare month.
http://blogs.zdnet.com/hardware/?p=2179

Time for another prediction and to check up on my older ones.
I last predicted on February 1st that Linux would displace Windows 2000 6.6 - 9.8 Months from them. We are now at the 6 month point and let's see what would be needed for that prediction to become true.

Currently Windows 2000 is at 2.11% and Linux is at .80%.
Windows 2000 is losing about .10 every month (average 6 months) and Linux is gaining about .03% every month.

Based on that data, it'll be another 10 months until Linux passes 2000. Far from the four more of my original prediction.

To actually make the "6.6 to 9.8" prediction true they would need to reduce the delta between them by .3275% every month.

My first prediction would require Linux to beat Windows 2000 by the end of this year, which would require the delta to shrink by .22 % every month.
I think that is doable, oh right and 1% at least by the end of the year as well (if not sooner)

Edward Corrado: Library Sacred Cow #1

Fri, 07/18/2008 - 15:27

Andrew Pace had an interesting post about library Sacred Cow #1: patron privacy. His solution is to provide different levels of privacy to patrons. Basically his approach is having a privacy setting scale similar to what you be familiar in a web browser and let the patrons choose. Personally, I think this would be a great approach. Patrons are wise enough to make there own decisions on this. If a library choose to implement something like this, I think it would be prudent for the library to describe the pros and cons of choosing different settings (and should make the default very protective of privacy).

Many patrons would love to have this choice. On a number of occasions at the reference desk or over the phone a student or faculty member wanted to know what book they checked out a few weeks ago and I couldn’t help them because we didn’t have that information readily available. I have heard from people who work in interlibrary loan at different colleges about patrons wanting similar information about articles they requested in the past. These are just very basic examples. I think it is obvious that if we collected circulation and other information we could provide better service to our patrons, be it recommender systems, customized new book alerts, etc.

The question is, why don’t libraries do this? One reason is that no one has really built tools that can handle this type of system (although with the advent of VuFind, the eXtensible Catalog, and other projects, this is beginning to change). There are, of course, librarians who are, rightly so, worried about privacy. However, if adult patrons are giving an educated choice, this argument is almost a non sequitur to me. In fact, but not providing this choice, it is conceivable that we are opening patrons up for more risks to their privacy as they use other tools and services outside the library that will not be protected by state library privacy laws.

I am concerned about privacy as much as most librarians, but at some point we have to make a decision. If we are going to make information and services available to patrons there is always an offset between privacy and access. The only way we could avoid all possible privacy implications about patrons using our resources is to not make any resources available to them. So, we are already making a sliding scale between access/service and privacy — only we aren’t letting the patron make their own decision. We are making it for them. One thing I believe libraries need to be concerned with is the amount of information available outside of libraries. If we don’t make our quality information easily available, people will go elsewhere. If this happens in large enough numbers, we won’t have to worry about patron privacy, because we won’t have any patrons.

In one of the comments to this post, Roy Tennant mentioned that he is that he is baffled by the reflectance to adopt a solution such as Pace proposes. Roy writes “I think a lot of folks have forgotten the days when there were cards in the book that listed everyone who had checked the book out. Where was privacy then?” This is a good question. Some librarians like to dwell on all of today’s privacy risks while at the same time ignoring what libraries have done long before the turn of the century and the advent of Library 2.0.

Whenever a discussion about Library 2.0 applications come up in a conference session or an an e-mail list, almost invariably someone brings up privacy as a reason not to do this. Recently, I remember reading a blog post, e-mail, or article (sorry, I couldn’t find it anywhere) where someone questioned if the real reason some librarians bring up privacy in because they are afraid or against change. I wouldn’t go that far, but I do think that it may be part of it. I do believe most librarians are legitimately concerned about privacy - however we shouldn’t let this concern be the end-all of our being. We need to find ways to provide these enhanced services while still working to protect privacy of our patrons. I think Pace’s concept could be one tool in our arsenal for doing this.

J.D. Abolins: Schneier & UW team "crack" Truecrypt v=<5.0 deniable file system

Wed, 07/16/2008 - 19:55
This afternoon, Dark Reading reports:
Schneier, Team Hack 'Invisibility Cloak' for Files
Researchers break 'deniable file system' steganography feature that conceals the existence of sensitive files from hackers
JULY 16, 2008 | 5:35 PM

By Kelly Jackson Higgins
Senior Editor, Dark Reading

[...]
The researchers were able to get around DFS in versions 5.0 and below of TrueCrypt’s encryption-on-the-fly tool, and will present their findings on the hack at the Usenix HotSec ’08 summit next week in San Jose, Calif.

[...]
Schneier, who has studiedthe viability of the so-called “deniable” file system model in the past, says DFS is actually easier to hack than encryption, and that there may be no way to make files truly undetectable on a drive. “Deniability is a much harder security feature to enable than secrecy,” he says. [...]

The researchers were able to crack DFS without decrypting it. “Breaking the security of a DFS does not require decrypting the data; it only requires proving that (or in some cases simply providing strong evidence that) the encrypted data exists,” according to the report, which was co-authored by Schneier and University of Washington researchers Alexei Czeskis, David St. Hilaire, Karl Koscher, Steven Gribble, and Tadayoshi Kohno.

The researchers found that Windows Vista shortcuts can give away the existence of a hidden file. Vista, which automatically creates shortcuts to files that get used, then stores the shortcuts in the Recent Items folder. And the auto-save feature in Word, meanwhile, saved versions of the hidden files.

[...]
“Modern applications and operating systems are very complicated, and interact with each other in many different ways,” Schneier says. “Hiding the existence of something means controlling all those interactions, which turns out to be a very hard problem.”
Quite interesting. I am looking forward to the presentation whenever it becomes available on the USENIX Conference Proceeding site.

Related reference: Truecrypt's explanation of its Plausible Deniability approach.

UPDATE (17 July 2008):

Bruce Schneier & UW team's research paper "Defeating Encrypted and Deniable File Systems: TrueCrypt v5.1a and the Case of the Tattling OS and Applications" is now available at
http://www.cs.washington.edu/research/security/truecrypt.pdf
and
http://www.schneier.com/paper-truecrypt-dfs.html

Although Schneier has not yet mentioned the paper on his blog, some comments about Truecrypt and plausible deniability appear under his recent post "Using a File Erasure Tool Considered Suspicious".

I sometimes slip in "deniable plausibility"; it's hard to believe,

Edward Corrado: Apple v. Psystar Corp

Tue, 07/15/2008 - 16:10

I haven’t been able to find a copy of the complaint yet, but Apple has finally sued Psystar Corp over the Mac clones they have been marketing. The articles seem to claim that the lawsuit is based on copyright infringement. I assume they are also saying they are violating the EULA. The copyright issue would, as far as I can tell, apply if Psystar is modifying any non-Open Source code (remember, some of OS X is licensed with a BSD license). It will be interesting to see how far Psystar takes this. In past interviews they claimed that the EULA Apple has is violating U.S. monopoly laws. It would also be interesting to see how far this suit tests the idea of the EULA and if Psystar can somehow test to see if the first sale doctrine when it comes to shrink-wrap software will held up in courts.My guess is that Apple probably has a good chance of winning, or otherwise having this case settled in their favor, this based on the merits (and it doesn’t help Psystar that they have many more resources to fight this case in court). However, I would like to see some of the terms of these more thorughly EULA tested in court. Hopefully I’ll find a copy of the complaint sometime soon so I can actually see what Apple alleges in the complaint instead of some tech-writers interpretation.

J.D. Abolins: Last HOPE conference NYC July 18 - 20

Tue, 07/15/2008 - 09:20
Information about the conference at http://www.thelasthope.org
Speaker/ Talks info: http://www.thelasthope.org/talks.php
Conference schedule: http://www.thelasthope.org/matrix/
Discussion site: http://talk.hope.net

Since 1994, the Hackers on Planet Earth (HOPE) conferences have been held in New York City every other year. The HOPE conferences are organised by the folks who publish 2600 - The Hacker Quarterly.

These conferences bring together an interesting variety of people from all over the world, including technology fans, tinkers, academics, cryptography folks, cyber-liberties activists, and, of course, hackers of all kinds as well as people interested in hacker culture.

This year is going to be difficult for time but I hope to make it out for one of the days.

One of the presentations that should be very interesting is Johnny Long's "No Tech Hacking". I've seen him give such a presentation at TechnoForensics 2007 and it's both fun and thought provoking. The no tech aspect is a good eye-opener for people who get so focused upon technical/cyber security issues that they forget the low/no tech gotchas. (Hint for organisations with special security concerns that was conveyed by a couple of the slides: Don't put agency logos on laptops, laptop cases, etc. Advertising might not be your friend. <g>)

HOPEfully,
