Houston - It's Hot!

Awkward but not Brave - Brené Brown stays on Spotify

2022-02-13T08:00:00.071-06:00

Brené Brown, a research professor at the University of Houston, decided on Feb 8 to keep her podcasts on Spotify after pausing her podcasts on Feb 1 in the face of the platform’s choice to continue streaming Joe Rogan’s inflammatory podcast. Although she made a career from “Daring Greatly,” her choice was awkward and not brave.

In a post explaining her decision, she argues that because she has an exclusive contract with Spotify, she has fewer options than artists who can make their music available on other platforms. She compares Spotify to a cafeteria where people can come in and sit where they like justifying her association with a platform that hosts Joe Rogan because her fans needn’t “sit with them.” Neither point is convincing.

I’d like to address the free speech cafeteria analogy first because I think it misses some important facts.

Although Brown would like us to think of Spotify as a cafeteria, Spotify is more like a concert (or a festival) with headline acts. The most important difference is the money involved. Brown and Joe Rogan are like headliners at the show; they’re each convincing their fans to come and, when those fans come to Spotify, they either pay a subscription, or have to listen to advertisers, or both. That money is then used to pay Brown and Rogan for their exclusive contracts. And much like a concert or festival, some acts almost certainly get paid more (Rogan) than others (Brown). Still, everyone coming to the show ends up paying some to each.

The exclusive contract actually compounds the problem. Because you can’t hear Brown’s podcast except on Spotify, her fans must give their subscription and/or attention to Spotify to hear the show. Thus, Rogan also gets part of his compensation from every one of Brown’s fans she brings to the streaming service. But all contracts can be terminated, even though that is likely to cost Brown money and opportunities.

Brown says that “words matter” and that some of the content on Rogan’s podcast made her “physically sick”. The distance between Brown and Rogan comes across as being about more than just misinformation, a part of the Joe Rogan podcast that Brown thinks Spotify is beginning to address. Brown also seems concerned about core values and how they’re expressed in public. In fact, in her cafeteria analogy she says “sharing the table with Rogan puts [her] in a tremendous values conflict with very few options”.

One of those options is to stop sharing the table and to find a new (or return to an old) way of publishing her podcast. If her values are that much in conflict with Rogan’s, then she can make the decision not to force her fans to subsidize the Rogan show. It should, in fact, be “me or Joe”.

It’s great that Brown states that “I’m always going to stand firmly on the side of free speech”. But that’s not what’s at issue here. Brown leaving Spotify, or asking Spotify to remove Rogan, doesn’t mean Rogan doesn’t have free speech rights. If he left Spotify, Rogan would find another platform and his fans would follow. I think this issue is not about censorship or free speech; it’s about making your fans buy tickets to a festival where someone else is spreading misinformation and saying hurtful and racist things. India Arie really said it best when she decided to pull her music from Spotify: ”This shows the type of company they are and the company that they keep.“

Brené Brown should be brave and choose not to keep company with Joe Rogan. Words matter, and actions matter. By staying on Spotify, Brown is signaling that the cost of leaving the platform is more than she’s willing to pay to keep her fans from subsidizing Spotify or Rogan.

Lawyering in Linux - E-signing a PDF

2019-04-03T08:00:00.000-05:00

I had the need the other day to e-sign a PDF that I hadn't myself generated. If I had generated the PDF, I could have easily stuck in the /s/ line myself on the signature line.

Luckily I had two great FLOSS tools to help: PDFtk and LibreOffice. The heavy lifting is done with pdftk and its multistamp operation. In my case, I had a 9-page PDF with signature lines on page 3 and page 9, so this is what I did:

Determine the pages and locations on each page where you need to add text (in this case, a signature) (you can also add images). I went ahead and printed out the two pages I needed and used a ruler, but you can eyeball it to start, because you're likely to need to iterate anyway.
Create a Writer document in Libreoffice. You can typically use libreoffice --writer to do this.
Generate enough page breaks to match the number of pages in the PDF file. If you have a LOT of pages, you might consider using pdftk to break up your PDF into individual pages, and process each page separately. That exercise is left to the reader.
On each page that needs, e.g., a signature line: create a table with two columns and two rows. Size the row height of the top (or bottom) row to get the other row in place. Then size the left (or right) column width to get the right cell into place. Make sure you uncheck "fit contents" so the row doesn't auto-resize.
- If you need more elements on the page, add more tables. You can put tables inside tables if you need to. Or, you can use frames or other elements to put text on the page.
- Don't forget to put your text and/or image into the correct cell!
Save the Libreoffice document as a PDF.
Use pdftk {PDF to sign} multistamp {PDF of signature(s)} output {Signed PDF} to sign the PDF. The output will have the name you gave to {Signed PDF}.
Pretty likely, this won't work the first time. So go back to step #4 and adjust your row and column sizes, or frame positions, or whatever, and try again. I think it took me 3 iterations.

There you go - your text and/or other elements will now be stamped on the PDF you inherited.

You might also take a look at stamptk in case that meets your needs! Keep in mind, though, that stamptk is a proprietary program, not FLOSS.

Look! I'm a lawyer!

Modifying free software

2014-04-07T15:24:00.000-05:00

I use the Debian distribution of GNU/Linux on various machines at home and at work. I've been using this distribution since the 1990s, and have been keeping it upgraded over various versions, so my configuration on my laptop has become increasingly customized and comfortable. I'm currently using the squeeze version (with some backports from wheezy). For a graphical user interface, I use XFCE4, version 4.6.2; the latest stable version available through Debian is 4.8. One of the nice things about this version is that it allows me to visually monitor my machine's performance as part of a panel, using a GNOME applet called "system monitor"; this GNOME applet integrates with XFCE via a bridge piece of software called xfapplet.

Note that I'm "one version behind" for both the Debian and XFCE projects. The reason I'm not upgrading either set of software is because the xfapplet bridge that allows me to use GNOME system monitor does not exist in these new versions. I have heard that GNOME has been changed dramatically in its new release (going away from "applets" and using a new paradigm called "indicators"); this may make it difficult for the maintainers of xfapplet to upgrade it to the new versions of GNOME and XFCE.

My solution is to make my own version of the parts of GNOME system monitor that I use. I will start with the excellent xfce4-cpugraph-plugin applet. From there, I intend to make two sets of changes:

Modify xfce4-cpugraph so it shows different colors for each type of CPU used. This will allow a user to tell, at a glance, how much CPU time is spend in the following modes: user, system, nice, IOwait.
Clone the modified xfce4-cpugraph to monitor memory (user, shared, buffer, cached); network (in, out, local); swap space (used/free); system load (moving average); hard disk usage (read, write). Each of the graphs will stand alone as its own plugin, so I'd end up with xfce4-memgraph, xfce4-netgraph, xfce4-swapgraph, xfce4-loadgraph, and xfce4-diskgraph. Users can chose whatever combination of monitors they'd like to install in their xfce4-panel. I may disable the "bars" on the cloned versions of the graphs; I certainly wouldn't be using them.

One caveat: the current plugins are designed to work not only on Linux but on various other operating systems that XFCE works on: FreeBSD, NetBSD, OpenBSD, and Sun/Solaris. I am not going to make the "clone" plugins work on any kernel other than Linux. Also: I plan to modify the upstream code in the XFCE repository, not the Debian package. I may be able to help the Debian maintainer package the projects, if that helps.

Want to help? Please let me know.

I passed the bar exam!

2014-04-01T08:00:00.000-05:00

After four years of school, five months of studying, three days of exam, and lots of life in between, I passed the Texas Bar exam. That is a BIG relief.
I actually can't even put that feeling into words.

Blowout!

2014-03-31T21:29:00.000-05:00

I brewed ales and meads with a group of friends for about two years, starting twenty years ago. I stopped after a while; friends moved away, and it just didn't fit into my schedule for a while. I'm pretty happy to be starting back up.

This weekend I brewed two fermented beverages: a mead (technically metheglin: fermented honey, ginger, and cinnamon), and a porter ale. The latter is a dark ale with moderate bitterness, and was the source of some trouble. I was up until 4am nursing a cranky batch of beer, and my bathroom is currently (pleasantly) scented with the aroma of hops and barley.

The porter I brewed, like most ales, is made of water, sugars and starches from malted barley, and hops (for flavoring and preservation). This concoction is called the wort. When the wort is cool, yeast is added; the yeast will convert most (sometimes all) of the sugars into alcohol. The hops release their oils during the boiling process; these oils impart flavor to the finished beer. The yeast, as part of its fermentation process, generates carbon dioxide as a byproduct.

This fermentation process usually takes place in a carboy:
. At the top of the carboy in the picture, you can see what's called an air-lock; this allows the carbon dioxide to escape, and prevents oxygen (and anything else) from coming into the carboy. When things are going well, the air-lock will make a bubbling sound, often about once per second (sometimes more frequently, especially at the beginning, and sometimes less frequently, as the sugars are converted). If the carbon dioxide cannot be released, the air-lock may be expelled rather forcefully from the carboy. While the wort is fermenting, heavy particles sediment out to the bottom (the trub), and lighter particles and oils rise to the top (kraeuzen).

It was the kraeuzen, the bitter oils and particles, that clogged up my air-lock on the porter. I returned home from an evening out, to find the air-lock across the room, and kraeuzen all over the carboy. I attached a blow-off tube to the air-lock's stopper, and allowed the kraeuzen to continue to bubble out overnight; when I finally heard it start bubbling steadily (around 4am), I was able to re-sanitize the air-lock, and attach it back to the carboy.

Because there was steady fermentation the whole time, I'm pretty sure there was positive pressure heading out of the carboy at all times; I'm pretty sure no contaminants entered during the process. Nevertheless, I'm going to keep my eye on it pretty closely over the next few days.

If you have any questions about brewing or any recipes, please ask!

What I'm glad I did in law school

2014-03-24T01:00:00.000-05:00

I don't want to post ad nauseum about the bar exam and my law school experience. I'm also not representing this as "how to pass the Texas bar exam" because for all I know at this point, I've not yet accomplished that. Instead, here are some classes I'm glad I took, and experiences I found relevant, once I started the bar review process.

For the MPT

The MPT is an exercise in which you are given a packet with some made-up court cases, made-up law(s), made-up facts, and a task, usually to write a memo or some persuasive brief. In my opinion, this is probably the most valuable part of the bar exam, especially for potential solo practitioners; it simulates what you'd have to do to come up to speed quickly in an unfamiliar area of the law in order to solve a problem for a client. I'm really glad I took an extra research and writing course, a course in "advocacy" (at the appellate level), and I interned with an appellate court. Other things that might be good for this exercise might be to clerk for a law firm, and to compete in mock trial or moot court competitions where you need to do more research and writing.

Interestingly, and just by chance, I found my internship with an immigration lawyer particularly relevant during this part of the bar exam; the specific task I had on my MPT was to write a brief in support of a client who was trying to show his marriage was bona fide for immigration purposes. It was nice to feel familiar at least with this area of law, even though all the court cases and statutes were made-up.

For the MBE

The MBE is a (pretty difficult) multiple-choice examination covering the basic topics you learn as a first-year student (1L). I'm really glad I took additional courses in Evidence and Criminal Procedure. That pretty much rounded out the topics on the MBE for me. I also apparently had pretty broad-ranging classes in Real Property and Torts as a 1L; often, when the review professor in those areas said "You probably didn't cover this in your 1L class", it wasn't true for our class.

Other than that, I found it really helpful to do lots and lots of practice questions, and then to review the ones I got wrong. A small number I got wrong more than once, which was embarrassing, especially because I probably got those wrong on the bar exam as well. Oh well.

For the Texas Procedure and Evidence short-answers

The Texas bar exam asks 20 questions about criminal procedure and evidence, and 20 questions about civil procedure and evidence. Each question is answered in up to 5 lines of handwritten text. I was pretty happy again for having taken Evidence as well as Criminal Procedure. I have the feeling (and no first-hand experience to back it up!) that participating in mock trials, trial advocacy training, and as an intern in a trial court or district attorney's office would be helpful here too.

For the Texas subject exams

The Texas subject exams are 12 essay questions over two three-hour sessions. Just doing that much writing was pretty exhausting. The subject areas were pretty broad, too.

During the bar review, I was again pretty thankful for my 1L class in Real Property because we covered topics such as landlord/tenant law. I'm also glad I took Family Law, Trusts and Wills, Federal Income Tax, Business Organizations (which included a chapter on Agency), and Texas Consumer Law. Because I took those classes, those sections of the bar review were truly review for me.

Areas I didn't take classes in were Oil and Gas, Guardianship, Secured Transactions, and Commercial Paper. I found those pretty easy to pick up, partly because I found them pretty mechanical, and partly because I could focus on them and just review the other subjects.

If your school offers bar prep classes, such as for the MPT, you might consider taking them. On the other hand, I really can't imagine taking the bar exam without taking a bar reivew/prep course, so if you are sure you will take a review course anyway, then maybe you should take more substantive courses during your time at law school. If you've got the resources, it might not hurt to start practicing MBE questions with an online question bank "ahead of time", maybe during your 3L year, especially if you feel comfortable already with Evidence and Criminal Procedure. If don't already know those areas, then wait for the review course to teach you the basics in those subjects, because otherwise the review questions are likely to be frustrating.

One last thing. I ended up choosing to hand-write my exams, mostly because I'd already seen the bar exam software freeze up or fail for various classmates during final exams at law school (in fact, it even happened to me once). Although I still wonder if that were the right decision, I doubt it made much of a difference. I would have been better served doing a lot more hand-writing practice during the bar review process; most of the practice was online and typed, which was a very familiar environment. Time management is different when you hand-write, at least for me; I can type 80-90 words a minute, and certainly can't write that much. I think my hand-written essays were a bit shorter than typed ones would have been. In the end, it doesn't matter as long as I pass the bar exam; I wasn't going to get the top score even by typing, so unless hand-writing put me below the passing grade, I'm okay. Just saying if you make that choice for taking the bar exam, you might consider practicing time management while writing lots and lots of essays over a six-hour stretch.

Schrödinger's Lawyer

2014-03-10T11:07:00.002-05:00

Well, I just finished taking the February 2014 Texas Bar Exam. I'm in a strange quantum state between lawyer and non-lawyer; I feel a bit like Schrödinger's cat. The Board of Law Examiners (BLE) has my completed exam; it's sufficient to determine if I'm eligible for admission to the State Bar of Texas. The BLE will collapse that wave function when they open, grade, and scale/curve the exam. The function won't collapse for me or anyone else until May 1, 2014, when the results are announced.

There was a really interesting article in Scientific American about the relational interpretation of quantum mechanics; unfortunately, this article is now behind a paywall. What makes this interpretation so compelling to me was the confirmation that the cat knows the outcome before the box opens. Each potential observer has their own wave function; an observation event by that observer collapses the potential states of the system into an observed state for that observer. Much as the special theory of relativity describes how different observers in different accelerating frames may perceive sequences of events differently, this theory of quantum mechanics eschews a single, canonical wave function and "collapse". To me, discovering the relational theory was so freeing; the "objective" theories, including even the quite compelling "many worlds interpretation" with its infinite alternate universes (based on what quanta??), seemed to require too much compromise.

The sleep needs of adolescents

2011-03-31T08:00:00.046-05:00

HISD is considering moving HS start times EARLIER next year (look down toward the middle). But recent research implies that high school students do better later in the day; apparently puberty shifts the 'chronotype' of adolescents to an 'evening preference'. Some districts have shown improvement in student participation and behavior with later times. Other studies have shown a correlation between sleep deficit and reduced creativity and performance.

Of course changing start times for high school students also impacts school faculty and staff, and parents and families. Students may find it difficult to have after-school jobs, long extra-curricular activities, or away-games against schools in other districts. Nevertheless, it appears that with enough planning, the overall effects can be positive for all involved.

I recommend you read the article from the March 2011 issue of "Educational Researcher." Some of the references in the article may be available online if you can't get the link above; please see below.

Distinguishing Snyder from Rosenbloom

2011-03-13T08:00:00.041-05:00

University of Houston Law Center's Professor Leslie Griffin of the Religion Rogue blog analyzes the recent Supreme Court decision in Snyder v. Phelps in the context of an earlier case, Rosenbloom v. Metromedia. Professor Griffin suggests the Court may be moving toward a Free Speech analysis suggested by Justice Brennan in Rosenbloom, which protects speech about matters of "public concern" even when it causes harm to private individuals. I believe that Chief Justice Roberts's opinion in Snyder is written in such a way that its analysis is distinguishable from Justice Brennan's.

The speech in Rosenbloom which Justice Brennan suggested was protected was about Rosenbloom himself; he was described as "a main distributor of obscene material in Philadelphia." I believe that stands in contrast to the facts considered important by the majority in Snyder. As Justice Alito points out in Part IV of his dissent, the majority first confines their analysis to the placards at the funeral, putting aside the events before and after (which included a press release and an internet "epic"). Even in that limited context, the Court had to further decide that the "predominant theme" of the speech was of public concern, since some of the signs could also reasonably be interpreted as referring to the plaintiff or his family. The result was a conclusion that the speech in Snyder wasn't really about the plaintiff at all, which I believe is how the Chief Justice could conclude that it was in the category of speech afforded the most protection by the Supreme Court. I believe this is an important distinction between Rosenbloom and Snyder; if that's true, then we may not yet know if this court might adopt Justice Brennan's reasoning in a case applied to speech either about or targeted at a private individual.

American Academy of Actuaries on Social Security

2011-03-11T08:00:00.004-06:00

Who would be in a better position than the American Academy of Actuaries to evaluate a benefit plan like Social Security? I suggest reading this report on Social Security from the Academy, which explains why a safety net program like this needs to be a defined benefit plan instead of a defined contribution plan. From the abstract:

As originally conceived, Social Security provided monthly beneﬁts for life to covered workers who ceased employment after attaining age 65. Beneﬁts were calculated by a formula based on each worker’s employment history and were payable for life, regardless of how long the worker lived or the amount of taxes paid on his or her behalf while working. Thus, there was at best an indirect relationship between taxes paid and beneﬁts received.

Plans such as this, where the beneﬁts are determined according to a formula and generally paid for life, are called deﬁned beneﬁt plans. By contrast, plans that pay beneﬁts based on amounts accumulated in an individual’s account are called deﬁned contribution plans (or individual account plans).

Much has changed since Social Security was created. The program has expanded to cover new classes of beneﬁciaries, such as spouses of retired workers, surviving spouses and other family members of deceased workers, and disabled workers and their families. Many U.S. workers have also earned beneﬁts under employer-sponsored deﬁned beneﬁt plans. These developments account, in part, for the fact that the elderly now have the lowest poverty rate among all age classes.

However, over the past 25 years, many employers have dropped sponsorship of their deﬁned beneﬁt plans in favor of deﬁned contribution plans. Many Americans are now saving for their own retirements through employer-sponsored 401(k) plans (a type of deﬁned contribution plan), individual retirement accounts, and personal savings. Some people believe that Social Security would also work better if converted, in whole or in part, to a deﬁned contribution structure.

After careful study of the issues involved, the Social Insurance Committee of the American Academy of Actuaries has concluded that the deﬁned beneﬁt structure is preferable to the deﬁned contribution structure for providing basic retirement beneﬁts under Social Security. Because of its ability to tailor beneﬁts that meet the needs of beneﬁciaries in different circumstances and its inherent risk-sharing attributes, the deﬁned beneﬁt structure is more efﬁcient at providing the ﬂoor of retirement and disability protection needed by U.S. workers, particularly those least able to supplement their Social Security beneﬁts from other income sources. This conclusion is only strengthened by the trend toward deﬁned contribution structures among employer-sponsored retirement plans, since this leaves Social Security as the only remaining deﬁned beneﬁt plan for many workers. This is not to suggest that a deﬁned contribution approach should not be a part of Social Security reform, but this committee would support it only as a supplement to the beneﬁts provided under a basic deﬁned beneﬁt program.

The cost of public education

2011-03-09T08:00:00.006-06:00

A friend has re-posted some charts from a CATO Institute article on costs associated with public education. As you can probably guess, the article has a particular point it's trying to make; I'd like to point out some things that might be helpful before you read it.

The article refers to data collected from the NCES 2009 Digest. When you notice that the number of public school employees is growing at a faster pace than the number of enrolled students, it would be helpful to know the breakdown in the increase of employees - how many are teachers, staff, administrators, etc. That's available in this table from the National Center on Education Statistics (NCES) which shows that at least between 1990 and 2007 teacher salaries represent a pretty constant 61% of expenditures. Other subgroups (administration, staff, food services, transportation, etc.) keep pretty constant ratios as well.

How does this compare to private/religious school staffing at the same level? You can actually test that with this table, which shows that the number of teachers in the public sector rose 50% between 1980 and 2009 - but so did the number of teachers in private schools. The number of students has increased by roughly 26%. The net effect has been to drive down student/teacher ratios from 18.7 to 15.3 in the public sector; in the private sector the ratio went from 17.7 to 12.8.

On the bottom chart in the CATO article: As the source says: "Total expenditures for public elementary and secondary schools include current expenditures, interest on school debt, and capital outlays." Capital outlays include new technology, internet access, textbooks and materials, laboratories, school buildings, etc. Schools would, for example, save a huge amount of money by replacing obsolete Windows and Macintosh computers with state-of-the-art Linux machines. Table 182 confirms the graph; expenditures per pupil doubled from 1980 ($5695/student) to 2009 ($10,041/student).

But compare that to private schools: table 27 shows an increase in overall private school expenditures (in constant dollars) of 150% between 1980 (est. $20B) and 2009 (est. $50B). That compares to the public schools which increased 130% over that period, from $262B to $600B.

Does the increase in costs raise scores? chart 123 shows the scores stay pretty constant from 1992 through 2007. The overall scores for private schools are higher per grade; but that may be an effect of a self-selecting population. More interesting are the jumps from 4th to 8th grades (keeping in mind these are comparing apples to oranges to some extent, as students move around). Public schools increase the scores by 50 points over 4 years (a 1994 4th grader to a 1998 8th grader), and so do the private schools. As a percentage, the public schools raise scores 25% over the 4 years, while private schools raise them a little over 20%. That's an interesting result given the popularity of the new "value added" calculations used to assess teachers and schools.

Moving students from public schools to private schools would apparently increase the number of teachers required to maintain their low student/teacher ratio. How will that drive down the cost of education, other than by paying teachers individually less? Would increasing private school costs and lowering public school costs reduce the price of education overall - or would it instead shift the cost more directly to parents and reduce the cost to taxpayers without children? It would be a policy decision to decide if that's equitable - spreading what would essentially be the same cost over a smaller group of people.

Open source and 17 U.S.C. 203

2011-03-08T08:00:00.003-06:00

Section 203 of the US copyright statute* is an interesting provision which allows an author to terminate the right to use a work 35 years after the grant was made. There are good policy reasons behind this rule; an author may not be in an equal position to bargain with a publisher, and the value of a work may not be apparent when the grant is first made. The rule allows an author to re-negotiate for more compensation if it turns out that the right they sold (or gave away) turned out to be more valuable than initially thought.

Does this introduce any uncertainty in the rights you receive when you use free software? Do programmers and companies now need to worry that they can use free software for at most 35 years before the author has the right to tell them to stop? What about other software which builds on top of the first work - can the rug be pulled out from under them at that point, if the author decides they want to revoke the rights granted to you and instead sell the right to use software?

I believe there is little to no risk imposed by Section 203. First, 203(b)(1) specifically says that derivative works created before the revocation may continue to use the underlying work/code. This would generally protect anyone who has created any material modification of the work, or who has included it in a compilation (for example, a CDROM or other collection). A Freedom Toaster might be an example; any Linux distribution such as Debian GNU/Linux would be another.

Second, section 203(a)(4) (and 37 C.F.R. 201-10) impose strict notice requirements on an author, including, for example, a requirement that the revocation be in writing and that delivery be made by US mail or in person. These might make it expensive for a programmer to contact each grantee to revoke their rights.

The third consideration is interesting; section 203(a) states the requirement that the grant be "executed by the author." Both the GNU Public License (GPL) (section 2) and the Creative Commons licenses state that when you distribute/convey a work to someone else, the recipient is granted a license directly from the author(s); the GPL specifically states that no sub-licensing is involved. This seems to imply that an author could revoke the license to use their piece of free software as long as they comply with the rest of the provisions of section 203 and with the C.F.R. Of course, that would require an author to know exactly when you received the software; the 35 years runs from the time of the grant, which they may not know if you got the code from source other than them. Consider too: what would happen if you receive a revocation from an author and a subsequent copy of the work under the GPL? Would the terms of the GPL mean that the author has agreed to re-license the work to you, as is allowed under sections 203(b)(3)-(4)? That interpretation seems consistent with the language in the statute.

Finally, the "life cycle" of software is fairly short; it's pretty unlikely that a piece of code will remain valuable for more than 35 years. Nevertheless to remove risk entirely, it might be prudent for a recipient to document when they first receive a work under a free software license and to plan to replace the code in 35 years if it's still in use.

For all these reasons, I believe the risks to recipients of free software from provisions in section 203 are minimal, can be easily avoided, and can likely be ignored pretty safely.

*In case you were wondering: section 304 paragraphs (c) and (d) only allow authors to terminate grants prior to 1/1/1978. The first version of the GPL was in 1989, well after that date, so those provisions don't apply here. It's my assumption that 1989 is the first time a free software license was used for works in the United States.

Sticks and stones

2011-03-06T08:00:00.002-06:00

may break your bones, but names can never hurt you; the Supreme Court decision in Snyder v. Phelps reminds me of the schoolyard taunt. The opinion seems to take great care to point out that all that was analyzed was the picketing activity of Westboro Baptist Church at the funeral of Matthew Snyder; the broader context of the conflict between Snyder and Phelps, which included television and internet publications, was explicitly not discussed by the majority or the concurrence. This case involves the interaction between two different parts of the law.

The first is an area of torts law; the lower court found that the Church had intentionally inflicted emotional distress (IIED) on Albert Snyder, the father of the Marine whose funeral the Church picketed, and one of the persons targeted directly by the Church's related writings. IIED requires a jury to decide that intentional, extreme, and outrageous conduct by the defendant caused severe emotional harm to the victim. In this case, the jury in the lower court did find the behavior of the Church outrageous, and awarded Snyder damages. The right of Snyder to sue for these damages is established by the State.

The second is First Amendment jurisprudence - in this case, the right to speak freely. The Court has allowed the State to constrain that right in certain cases, on a continuum from most protected to least protected. When the government attempts to interfere with the most protected speech, the Court applies the highest level of scrutiny, and the government usually loses. In this case, the Court looked exclusively at the behavior of the Church at the funeral and decided that the picketers were in a public place, making statements of broad public concern, not ones exclusively targeted at the Snyder family. Because this falls into the category of "most protected speech" the government must show that any restriction on it is very narrowly tailored to serve a compelling interest.

There are a number of things to look at in a decision like this. First, the dissent argued that the speech involved in the conflict between the Church and Snyder could reasonably be characterized as targeted when analyzed as a whole (including the television and internet postings). The majority decided that the predominant theme of the messages on the placards at the funeral were speaking to issues of broad public concern - America's tolerance of homosexuals. It's clear that what you include in the analysis will affect the outcome in a decision like this. Targeted speech of a certain kind was considered less protected in a case called Chaplinsky v. New Hampshire; that lower level of protection may have made a difference in this case.

Next, the compelling interest in this case would be the State's desire to protect its citizens from emotional attack. The Court has spoken in this area earlier in a 1988 case called Hustler Magazine v. Falwell. There the Court looked at speech that was targeted at a public figure. Despite the targeted nature of the piece, the Court decided that the State's interest in protecting the emotional well-being of a public figure could not overcome the speaker's right to create the parody in question. Had the Court in Snyder v. Phelps decided that the speech was targeted at Snyder and that Snyder was not a public figure, they might have given some guidance about the balance between the State and the speaker in this different configuration. Instead when they decided that the Church's message was of broad public concern, they put the speech into a category which the State is rarely allowed to regulate, because the Court believes the government may not interfere with the free discussion of ideas important to a politically informed citizenry.

Finally the Court addressed the issue of whether the definition of IIED was narrowly tailored enough to survive the strict scrutiny it imposed. In a statement which echoed a similar analysis in last year's United States v. Stevens, the Court reiterated that it was inappropriate to allow the over 50 jurisdictions in the United States to apply what are essentially local criteria in restricting speech. In the Federal statute at issue in the Stevens case, punishment could be imposed when the material was "illegal in the State in which the depiction is created, sold, or possessed", giving up to three different jurisdictions a chance to criminalize the video; in this case, each local jury could apply its own definition of "outrageous conduct" as described above. The majority decided that such a definition did not give enough guidance about what speech should be punished, and thus could reach even the speech in this case, which they decided was highly protected.

Although the opinion said multiple times that the decision was very limited to the facts in this case, we may be seeing a clue that IIED cases will be analyzed very strictly in future speech cases. On the other hand it may be that this analysis only implicates speech of public concern in a public forum, and that the outrageousness requirement may survive a lower level of scrutiny in different circumstances. If such a case comes up, we may see if the Court decides that some words, like sticks and stones, can hurt you, and be punished.

Infringement risks using free/libre software

2011-02-27T08:00:00.000-06:00

A recent article on the IP Info Blog outlined some potential risks for companies using free/libre software in the products they distribute. I have a quick response.

An entity which does not desire to disclose code or otherwise conform to copyleft obligations in products it distributes to others should be able to minimize their risk of infringement by interacting with GPL code using only standardized, royalty-free interfaces (such as POSIX for the Linux kernel). I don't think it would be unreasonable to invoke copyright law's merger doctrine when using header files which implement such an API; there are only so many different ways you can implement such a freely usable interface. This may be an argument Google might employ were it to be challenged for its distribution of Android (with the Apache license) on top of a modified version of Linux (which it continues to distribute under the GPLv2, as it's required to do).

Any other interaction would apparently involve a lot more risk, probably enough to convince such an entity that it should not use code covered by the GPL or some other "copyleft license" at all. I believe that result would not be incompatible with the intent of the authors who release their code under such licenses.

Judge Posner channels Roald Dahl

2011-02-02T08:00:00.001-06:00

In 2004, Neil Gaiman sued Todd McFarlane for a declaration that he was co-author of a set of characters from the Spawn series. Judge Posner wrote the opinion, in what ends up being a fairly conversational fashion. The details of copyright ownership analysis are technical, but the tone of the opinion sounds a bit like he's explaining the outcome to you over a beer.*

One of the issues in the case is whether a particular character can be copyrighted at all. Some characters are generic; others are described in detail with immediately identifiable attributes (Harry Potter's scar); and most fall somewhere in between. One of the characters in dispute was known as "Medieval Spawn," a fairly generic term; that might have been an issue, but Judge Posner points out that the Lone Ranger's name wasn't widely known (it's John Reid!), but he's a recognizable character. Most amusing is the Judge's discussion of the difference between characters in books and characters presented in visual form (comics, movies, TV, etc.). After a long passage on page 661 from The Maltese Falcon describing the detective character Sam Spade, Judge Posner says:

Even after all this, one hardly knows what Sam Spade looked like. But everyone knows what Humphrey Bogart looked like. A reader of unillustrated fiction completes the work in his mind; the reader of a comic book or the viewer of a movie is passive. That is why kids lose a lot when they don't read fiction, even when the movies and television that they watch are aesthetically superior.

Apparently the actual published opinion (not the one on Google Scholar) has a picture of each character attached, each in its own appendix. I guess they were copied with permission of both parties, or their inclusion is considered fair use.

* I'm not sure if Judge Posner drinks beer or not. It's just an expression.

Freedom of speech

2011-01-17T17:07:00.000-06:00

Justice Holmes, joined by Justice Brandeis, in his dissent in Abrams v. United States:

... But when men have realized that time has upset many fighting faiths, they may come to believe even more than they believe the very foundations of their own conduct that the ultimate good desired is better reached by free trade in ideas - that the best test of truth is the power of the thought to get itself accepted in the competition of the market, and that truth is the only ground upon which their wishes safely can be carried out. That at any rate is the theory of our Constitution. It is an experiment, as all life is an experiment. Every year if not every day we have to wager our salvation upon some prophecy based upon imperfect knowledge. While that experiment is part of our system I think that we should be eternally vigilant against attempts to check the expression of opinions that we loathe and believe to be fraught with death, unless they so imminently threaten immediate interference with the lawful and pressing purposes of the law that an immediate check is required to save the country.

Justice Brandeis, joined by Justice Holmes, in his concurrence to Whitney v. California:

Those who won our independence believed that the final end of the State was to make men free to develop their faculties; and that in its government the deliberative forces should prevail over the arbitrary. They valued liberty both as an end and as a means. They believed liberty to be the secret of happiness and courage to be the secret of liberty. They believed that freedom to think as you will and to speak as you think are means indispensable to the discovery and spread of political truth; that without free speech and assembly discussion would be futile; that with them, discussion affords ordinarily adequate protection against the dissemination of noxious doctrine; that the greatest menace to freedom is an inert people; that public discussion is a political duty; and that this should be a fundamental principle of the American government. They recognized the risks to which all human institutions are subject. But they knew that order cannot be secured merely through fear of punishment for its infraction; that it is hazardous to discourage thought, hope and imagination; that fear breeds repression; that repression breeds hate; that hate menaces stable government; that the path of safety lies in the opportunity to discuss freely supposed grievances and proposed remedies; and that the fitting remedy for evil counsels is good ones. Believing in the power of reason as applied through public discussion, they eschewed silence coerced by law — the argument of force in its worst form. Recognizing the occasional tyrannies of governing majorities, they amended the Constitution so that free speech and assembly should be guaranteed.
Fear of serious injury cannot alone justify suppression of free speech and assembly. Men feared witches and burnt women. It is the function of speech to free men from the bondage of irrational fears. To justify suppression of free speech there must be reasonable ground to fear that serious evil will result if free speech is practiced. There must be reasonable ground to believe that the danger apprehended is imminent. There must be reasonable ground to believe that the evil to be prevented is a serious one. Every denunciation of existing law tends in some measure to increase the probability that there will be violation of it. Condonation of a breach enhances the probability. Expressions of approval add to the probability. Propagation of the criminal state of mind by teaching syndicalism increases it. Advocacy of law-breaking heightens it still further. But even advocacy of violation, however reprehensible morally, is not a justification for denying free speech where the advocacy falls short of incitement and there is nothing to indicate that the advocacy would be immediately acted on. The wide difference between advocacy and incitement, between preparation and attempt, between assembling and conspiracy, must be borne in mind. In order to support a finding of clear and present danger it must be shown either that immediate serious violence was to be expected or was advocated, or that the past conduct furnished reason to believe that such advocacy was then contemplated.
Those who won our independence by revolution were not cowards. They did not fear political change. They did not exalt order at the cost of liberty. To courageous, self-reliant men, with confidence in the power of free and fearless reasoning applied through the processes of popular government, no danger flowing from speech can be deemed clear and present, unless the incidence of the evil apprehended is so imminent that it may befall before there is opportunity for full discussion. If there be time to expose through discussion the falsehood and fallacies, to avert the evil by the processes of education, the remedy to be applied is more speech, not enforced silence. Only an emergency can justify repression. Such must be the rule if authority is to be reconciled with freedom. Such, in my opinion, is the command of the Constitution. It is therefore always open to Americans to challenge a law abridging free speech and assembly by showing that there was no emergency justifying it.

On Sarah Palin and inspiration

2011-01-10T20:13:00.001-06:00

This response to a friend's blog re-post got too long for the comment box. There are a few questions to explore:

Was Sarah Palin responsible in any way for the Giffords shooting?
What about her free speech rights?
How does this compare to Mark David Chapman reading Catcher in the Rye?

Was Sarah Palin responsible in any way for the Giffords shooting?

18 U.S.C § 2(a), which is an example of a statute criminalizing aiding and abetting a crime, reads as follows: "Whoever commits an offense against the United States or aids, abets, counsels, commands, induces or procures its commission, is punishable as a principal." The key words a jury would consider in this case are probably counsels and induces. A prosecutor would work to convince a jury that Palin's writings and rhetoric convincingly counseled violence or induced it in the attacker. It's not a requirement that Palin be a necessary element; it's not necessary to prove that this attack would not have happened without Palin's contribution. A jury would just have to decide that Palin suggested or supported such an action.

Frankly, it's pretty unlikely any jury would reach that conclusion.

What about Sarah Palin's free speech rights?

The Supreme Court decided in Brandenburg v. Ohio that some violent speech is protected by the First Amendment to the US Constitution. The Court decided that States could only criminalize speech "where such advocacy is directed to inciting or producing imminent lawless action and is likely to incite or produce such action." This is a high bar for a prosecutor to reach in this case. Palin's web site was not apparently inciting imminent lawless action, and I don't think a jury would find that it was likely to do so either. While the web site listed individual lawmakers by name, and included gun sights targeting their districts, there was no direct call for violence, and most reasonable visitors would likely understand by the context that this was a political "call to arms" since this was published by the Palin PAC.

However the case isn't quite that open and shut. In 2003 the Supreme Court issued a relevant decision in Virginia v. Black, a case involving a statute criminalizing cross burning. While the defendants there claimed the statute infringed their right to free speech, the Court upheld the State's right to criminalize this form of expression because it was a "true threat"; the history of cross burning made this activity less an expression and more an intimidation. Here there is no statute prohibiting a publication of individual names with violent imagery, so Palin is not violating any law. However, if there were such a law, a prosecutor defending a conviction might look for evidence that such web sites have led to violence (e.g., against abortion providers) and try to make a similar argument.

Can you compare the Giffords shooting to the death of John Lennon?

Not really; an ambitious prosecutor would point out some salient differences. In particular, Sarah Palin did mention individuals by name, and placed gun sights (a symbol associated with violence) on their specific districts; Salinger's character did not shoot anyone, and especially did not mention John Lennon or anyone remotely like him. Because of these important differences, you can't say that just because it's unreasonable to associate Salinger with Mark David Chapman, it's therefore unreasonable to say Sarah Palin influenced Jared Lee Loughner. I think it's more compelling to do the analysis of her case on its own.

More browser security

The Electronic Frontier Foundation has released a new Firefox extension called HTTPS Everywhere. This extension will protect your online sessions (to some extent) by forcing your browser to use the more secure HTTPS protocol when an online provider makes that available. The rules apparently protect your use of Twitter, Facebook, Paypal, Wordpress, and other social and blogging networks.

If you want to use online services somewhat safely, use Firefox, with HTTPS Everywhere, Noscript, Petname, and other extensions which improve your browser security.

OurCourts is now iCivics

2010-11-19T08:00:00.002-06:00

I've written before about Justice O'Connor's OurCourts initiative which develops games and curricula for middle and high school students; the idea is to deliver lessons about the Constitution and our form of government in a more compelling fashion. My kids have pre-tested the games; but so have I, and they're pretty fun. The foundation is now called iCivics, and has expanded a bit; even if you visited them before, please check them out again, as they've added more content, especially for teachers.

Where there is injustice ...

2010-11-14T14:29:00.000-06:00

A quote from Chief Justice Earl Warren; it is apparently the epitaph on his grave stone:

"Where there is injustice, we should correct it; where there is poverty, we should eliminate it; where there is corruption, we should stamp it out; where there is violence we should punish it; where there is neglect, we should provide care; where there is war, we should restore peace; and wherever corrections are achieved we should add them permanently to our storehouse of treasure."

Justice Harlan on protecting liberty with the Fourteenth Amendment

2010-11-09T08:00:00.003-06:00

Excepts from his dissent starting on page 523:

Due process has not been reduced to any formula; its content cannot be determined by reference to any code. ... The balance of which I speak is the balance from which [our country] developed as well as the traditions from which it broke. That tradition is a living thing. A decision of this Court which radically departs from it could not long survive, while a decision which builds on what has survived is likely to be sound. ...

[The character of the Constitutional protection of liberties] must be discerned from a particular provision's larger context. And inasmuch as this context is one not of words, but of history and purposes, the full scope of the liberty guaranteed by the Due Process Clause [of the Fourteenth Amendment] cannot be found in or limited by the precise terms of the specific guarantees elsewhere provided in the Constitution. This "liberty" is not a series of isolated points pricked out in terms of the taking of property; the freedom of speech, press, and religion; the right to keep and bear arms; the freedom from unreasonable searches and seizures; and so on. It is a rational continuum which, broadly speaking, includes a freedom from all substantial arbitrary impositions and purposeless restraints ...

It is the purposes of these guarantees and not their text, the reasons for their statement by the Framers and not the statement itself, [ ] which have led to their present status in the compendious notion of "liberty" embraced in the Fourteenth Amendment.

Each new claim to Constitutional protection must be considered against a background of Constitutional purposes, as they have been rationally perceived and historically developed. ... The decision of an apparently novel claim must depend on grounds which follow closely on well-accepted principles and criteria. The new decision must take "its place in relation to what went before and further [cut] a channel for what is to come." (citing Irvine v. California, dissent).

This sounds pretty prophetic to me.

What do your online photos reveal about you?

2010-11-08T08:00:00.001-06:00

I've written before about the fact that all your data on the internet can become public at any time, and the fact that on your phone or other devices, "apps" can be disclosing your location or other information. Another thing to be aware of is that photos that you place on the internet can leak information about you as well.

What sorts of data are available in photos? Your camera puts in statistics about the photo itself: size, resolution, color data, etc. There's also information about the camera, information about the environment (including, in some cases, GPS coordinates), and date/time stamps. Some cameras apparently even let you "tag" photos, with things like the subjects/participants.

What can this tell other people about you? Well, that flattering and innocuous picture you put up as your profile picture on Facebook might have the GPS coordinates of a bar or nightclub. A collection of your pictures, tagged with location and date information, could let people know you travel a lot to expensive locales. Tagged pictures with names help others calculate who your friends are (or other people you hang around with). Sometimes information that's stored in just one picture is no big deal, but the photos in the aggregate can paint a picture of you that you might not expect. Read the article; you should at least know what can be in the photos.

Of course, photo upload sites like Flickr and Facebook could help you by purging that information for you. As a matter of fact they typically do when they convert your uploaded photo to another format or size; however, if the original file is still available for download, the information your camera saved in there will travel with it. And of course if the site may keep the original, or the data from the original, for its own use. You may decide it's not worth the trouble to sanitize your photos before you share them - but I think you should at least be aware of this issue.

Calculus, the musical

2010-11-01T08:00:00.003-05:00

Our family went to see Calculus, the musical when they were in town a year or so ago. It's an amusing play describing Newton's route to calculus, including old tunes updated with math lyrics. Some examples include:

5 Sizes of Numbers (In the style of: The Beatles - In My Life)
The Limit’s Alright (In the style of: The Who - The Kids Are Alright)
Differentiabul (In the style of: They Might Be Giants - Istanbul(Not Constantinople))
Power Rule (In the style of : Petula Clark - Downtown)
Under The Curve (In the style of: Red Hot Chilli Peppers - Under the Bridge)
and a favorite: L’Hôpital(I have Calculus in the Heart) (In the style of : Bonnie Tyler - Total Eclipse of the Heart)

At their web site they have some new albums for sale, and they say they're ready to come around on tour again. I'd love to figure out how to bring them to Houston, either to Rice or to a local high school. Anyone interested?

The value of being open

2010-10-29T08:00:00.001-05:00

The Register reports that the security on the iPhone 4 can easily be bypassed by a particular sequence of key presses. Apparently earlier iPhones suffered from a similar issue.

On a recent earnings call, Steve Jobs amusingly described Apple's iPhone as being more "open" than Google's Android operating system. If the iPhone really were in fact open at all, security problems like this would have more likely been found and fixed before they were widely distributed. End users would have been able to patch their own phones, if they wanted to, using the source code to Android itself. There are how-to articles and online support communities to help. And finally, if iPhone were really an open platform, other companies or enthusiasts could port Adobe Flash or Java to run on it.

The bottom line is you will never be able to fully trust your machine if it is running Apple software. You don't know if it's secure, and without source code you will never know if apps are stealing your data or are making transactions on your account. It's sad to hear Steve Jobs trying to claim the mantle of being "open" when it's so clear he wants to completely control the experience of every one of his customers - to their detriment, with at best an ephemeral benefit in return.
