This looks really useful: Google Reader (the web-based feed reader that I use to read the news) can create a feed from a page that does not publish its own RSS by “periodically visit[ing] the page and publish[ing] any significant changes it finds as items in a custom feed created just for that page.”

2009-12-21 GleeBox for Linux Chrome: Not Yet
I’m using the very fast Google Chrome browser for linux, and like it well enough to use it as my default. But I prefer mouseless selection of links, and the options for this are not yet mature. Gleebox looks excellent, but installing the current version (0.6) rendered the browser almost functionless. The only other option is Crossfire, which still needs development but at least works in most pages.

Aaditya Bhatia demonstrates how pretty plots can be produced with gnuplot, pointing out that those who complain of ugliness have failed to learn how to use the program well.
2009-11-04 Click-through rules and Finder Interface in Snow Leopard
The click-grammer and graphical interface in Apple’s latest Finder is still inconsistent, arbitrary and confusing. I only know this because of excellent articles such as this one. Because of stuff like this, and far worse, I use the unix shell on OS X to deal with files, and don’t touch the Finder.
2009-10-22 lxml vs. ElementTree
Michael Schurter presents a speed comparison. The comments on the page are informative, too. I should consider switching from elementtree to lxml.
2009-10-21 Elementtree Segfaults on Invalid XML Declaration
A commonly used XML parsing library for Python (the one that I use to make this website) gives you a segfault if you feed it an XML declaration of a certain variety.

“It used to be that business owners often struggled to afford advertising for their products or services. Google AdWords has changed that by offering an inexpensive way to spread the word. But if you don’t do some careful planning, you can easily find yourself spending thousands of dollars with little to show for it.”

A detailed look at the headaches that result from trying to collaborate through email, and how Wave seems to provide a more natural solution.
2009-10-15 Google Wave on the iPhone kills Safari's UI - and it feels great
Wave feels like a native application on the iPhone, partly because it is optimized for WebKit and partly because it exploits “app mode,” which hides most of Safari’s UI.
2009-10-13 Do Not Login to the Guest Account on Snow Leopard

2009-09-23 20 years of Apple laptops
Ars Technica skims the history of Apple’s laptop computers. I was sad that one of two I've owned, the “Lombard”, was skipped over in favor of the “Wallstreet” that preceded it and the “Pismo” that followed it. And I thought the author was too easy on the Duos; the 2300c, my other Apple laptop, always felt like a struggle to use, with a terrible, mushy keyboard and overall slowness. The Duos, while innovative, might fairly have been included in the “stinker” section. There is some revelatory history here: it turns out that what has become the standard design of the modern laptop apeared first in Apple’s PowerBook 100, introduced in October 1991.

2009-09-02 Gnuplot in Action is out
Philipp K. Janert’s book, Gnuplot in Action, is now offically out. The subtitle, “Understanding Data with Graphs,” is a clue to the depth and usefulness that this book appears to have, based on my skimming of the index and one of the free sample chapters. Gnuplot is the framework for detailed examples, but the book is much deeper than a manual for a particular program. It has many examples of various types of graphs and how they can be applied to the problems of understanding data. The best deal would be to buy the printed book and get the free PDF ebook.

2009-08-28 TidBITS Networking: Wi-Fi's WPA Encryption Is Not Broken (Yet)
This article by Glenn Fleishman should calm some people down: “The headlines on many tech sites trumpet, 'WPA Encryption Broken!' Hardly. A very small area of the Wi-Fi encryption method that's part of WPA and WPA2 is exploitable under very particular circumstances that don't reveal your network key or allow data to be intercepted and decrypted.”

2009-08-21 Wave Email Interop
Several articles about Google Wave have been pessimistic concerning its adoption, due to the assumption that everyone playing must have Wave installed, and that, for example, a Wave user would not be able to communicate with a user of old-fashioned email. But here is a report of a campout-contest where one of the developers won a third prize by whipping up a Wave-email gateway.
2009-08-19 FlightCaster: Flight Delay Prediction
They claim that they warn you of delays “6 hours before airline alerts.” There is a free web service and an offering in the iPhone AppStore. This looks really useful, especially in light of the typical quality of flight status information offered by the airlines (I’m at the gate, it’s already 20 minutes past boarding time, there is a big empty space where the plane is supposed to be, and the board says, “on time.”)
2009-08-18 Anil Dash on Google Wave
Mr. Dash has good wishes for Wave, but is pessimistic about its adoption, because “the Wave way is not compatible with the Web way.” He has an interesting argument, pointing out along the way that one of the foundations of the Wave protocol, XMPP, “is way too complicated for any normal human to deploy”.

2009-08-14 Automatic Bird Bath
We love feeding the birds, but water is helpful too, and attracts plenty of them. However, bird baths dry up quickly and get dirty every day. Here is a do-it-yourself system for solving both problems: “I have created a pictorial documentation of my low-maintenance bird bath, which has a dripper and a timer-controlled flush hose that cleans the bird bath once a day. I've included construction details in case anyone wants to borrow some of the ideas.”
2009-08-11 Would You Like a Phone That Does This?
“you can assign tags to task items that trigger alarms when you are in certain situations. For example, you can have a task to 'buy batteries' and assign it a tag of 'store' ... you connect the tag 'store' with a situation in which you are near your local hardware store ... I have a task called 'buy muni pass' which is only available a few days before the end of the month and only from certain retailers. I walk by a place that sells them, but I always forget to buy them during the window and I usually remember when I'm nowhere near the store.”
2009-08-10 Do Not Use URL Shorteners
J. Zeldman recommends an article by Joshua Schachter explaining why URL shorteners are bad and you should never use them (and adds an extra reason himself). They are right: these things are stupid and harmful and you should never use them unless there is no other choice. Publishers should use short URLs so that people will not need to shorten them. Zeldman uses some canned website software that has a URL shortening plugin, but it’s easy enough to use short URLs when you roll your own, as I do. A URL does not need to include the complete title of your article, the name of the author, and how you were feeling when you wrote it. It’s just an index into your content; it does not need to carry its own parcel of information.

“Mpmath is a pure-Python library for multiprecision floating-point arithmetic. It provides an extensive set of transcendental functions, unlimited exponent sizes, complex numbers, interval arithmetic, numerical integration and differentiation, root-finding, linear algebra, and much more. Almost any calculation can be performed just as well at 10-digit or 1000-digit precision, and in many cases mpmath implements asymptotically fast algorithms that scale well for extremely high precision work.”

Guss’ Pickles is leaving the Lower East Side and heading for Brooklyn because of high rent and a parking meter. I don’t meet many Americans my age, where I live now, who have eaten pickles bought from a barrel on the sidewalk in front of a shop occupying the first floor of an ancient tenement, unless, like me, they were lucky enough to grow up in the shadow of the eponymous side of the Manhattan Bridge. Those pickles were good.

2009-07-23 Unwebbable?
The insight of the article “Unwebbable” by an expert in web accessibility, Joe Clark, is that certain standard document forms convey their structure and semantics through visual layout and formatting, and that they can not be satisfactorily translated to HTML. The assumption implicit in the article is that there exist some documents that can be satisfactorily translated to HTML.

2009-07-02 Debunking Canadian health care myths
Rhonda Hackett, a Canadian clinical psychologist living in the US, writes a lucid article in the Denver Post:
“The U.S. has the most bureaucratic health care system in the world. More than 31 percent of every dollar spent on health care in the U.S. goes to paperwork, overhead, CEO salaries, profits, etc. The provincial single-payer system in Canada operates with just a 1 percent overhead. Think about it. It is not necessary to spend a huge amount of money to decide who gets care and who doesn't when everybody is covered.”

Kodachrome was superb technology. It took me a long time to learn how to use it, and then it became obsolete. But not really obsolete: film and digital are different media, although that’s not widely understood. Now, obsolete or not, it’s gone.
2009-06-17 Exclusive: Interview with Prof Seth Kalichman, author ofDenying Aids
Richard Wilson interviews the author of a book about the strange and sad story of AIDS denialists.
... all AIDS denialists pave the path for fraudulent cures and snake oil treatments. AIDS denialist[s] say that HIV does not cause AIDS, leaving open the question of what should be done to treat AIDS? Among the most notorious AIDS denialists are those who sell remedies, such as Matthias Rath and Gary Null who sell vitamins and nutritional supplements they have proclaimed treat HIV/AIDS.
2009-06-04 Google's Wave of the future is genius, but will it work?
A rare piece of recent journalism about Wave that actually contains some insight. But can you read it? For a while the Chicago Sun-Times wanted to make you pay after the article had aged for a month, as they regard aged news as more valuable than recent news. But it seems that it has aged sufficiently now (August) to be free again.

2009-04-28 ElementTree: Surprise in Handling Attributes
Nick Bastin gives an example showing that, while ElementTree’s behavior is, in a sense, correct and consistent, it is probably surprising and should be made to be correct and consistent in a less surprising way. If you use ElementTree (a python module for parsing and creating XML documents, that I use in building this site) you should read this.
2009-04-27 The X11 mess on OS X and how to fix it
You might have noticed that there are some problems with X-windows on recent versions of Apple’s OS X. And you might have been unfortunate enough to have tried to follow some of the plentiful bad advice on the web. The solution turns out to be simple: go here and download a version that runs with your version of OS X, and click to install. This will repair, for example, the bugs in the X11 that came with OS X 10.5.
2009-04-21 Parasite breaks its own DNA to avoid detection
The parasite Trypanosoma brucei, which causes African sleeping sickness, evades its host’s immune cells by periodically rearranging its DNA. When the host’s immune system has managed to almost wipe out the invader, some of the surviving parasites alter their DNA to change their surface coat, initiating another wave of infection, preventing the immune system from gaining the upper hand, and ultimately killing the victim.

2009-03-29 3D Plotting Software for Python::Part 1::PyX
Craig Finch notices that 3d plotting support has been removed from matplotlib, and experiments (as I have recently done) with using PyX to make surface plots. He develops a list of advantages and disadvantages; the most serious in the latter list is the inability of PyX to plot numpy arrays.
2009-03-21 Userfriendly it ain’t
Stephen Quinney says: “It has long been accepted wisdom that these mouse-driven office ‘productivity’ applications are in some way intrinsically more userfriendly than the command line or text file driven applications we are more accustomed to in Unix. Today I had the opportunity to prove to myself that this just isn’t the case.” I occasionally preach this gospel to those who will listen, but the message is for the most part drowned out by the predominant GUI habit.

Dr. Peter Lipson explains how Senator Tom Harkin, who is responsible for the National Center on Complementary and Alternative Medicine, is ramping up his assault on science and real medicine. Those who have any tendency to feel complacent about the correction of the Bush administration’s assault on science need to read this shocking description of a complementary assault coming from the Democrats.
2009-02-17 HTML5 Canvas Terminal for Gnuplot
This is fairly neat, especially as more browsers support the canvas element now (at least firefox, safari, and opera). The examples worked perfectly using firefox on OSX. It seems to work this way: setting the output terminal in gnuplot to canvas produces a javascript file that you can include in a page to display the graph, with some interactivity possible.

I am delighted to discover the excellent website Junkfood Science, offering “Critical examinations of studies and news on food, weight, health and healthcare that mainstream media misses.” Follow the link for a timely dose of perspective on the worry of the day: mercury in high fructose corn syrup. “There will always be people who try to scare us about some food [...] by telling us a small amount of some ‘toxin’ [...] has been detected. This is our heads up that we are being manipulated”.
2009-01-29 Attenborough Reveals Creationist Hate Mail for not Crediting God
“Sir David Attenborough has revealed that he receives hate mail from viewers for failing to credit God in his documentaries. ‘They always mean beautiful things like hummingbirds. I always reply by saying that I think of a little child in east Africa with a worm burrowing through his eyeball. The worm cannot live in any other way, except by burrowing through eyeballs. I find that hard to reconcile with the notion of a divine and benevolent creator.’”

2009-01-22 Wired Thinks it has Found a Google Docs Design Flaw
Employees of Wired are shocked to discover that their shared Google documents can be edited by anyone on the internet after they set them up to be edited by anyone on the internet. This article is the result. It attempts to blame the situation on a “design flaw” in the interface for setting permissions; apparently the flaw consists in the system not magically knowing who a user is before he signs in. You see, the Wired people clicked the box that says “Let people edit without signing in” but somehow thought that Google would know if they were on the list of approved editors anyway. By magic.
2009-01-13 What is this Avahi crap?
I know it’s supposed to be the linux version of zeroconf or Apple’s Bonjour, or whatever it’s called: some kind of autodiscovery for the network. But on both Ubuntu machines at home that use wireless networking, I had to root it out and destroy it before those machines could establish and reliably maintain an 802.11 connection. After getting rid of the Avahi crap, they work perfectly. Anyone care to explain to me why this is included and turned on by default, when it is so likely to create problems?
2009-01-08 Synectady
I enjoy the work of Charlie Kaufman and look forward to experiencing his Synecdoche, New York. I would like, in the meantime, to notice that its punning title was anticipated in 1970 by Peter Lubin in his essay “Kickshaws and Motley”, the subject of which is either Nabokov’s or Lubin’s love and use of words.
2009-01-07 Alaska authorities delayed arrest of woman connected to Sarah Palin, drug investigator claims
From the article in the Telegraph:
“Kyle Young, a drug investigator and state trooper, emailed the Public Safety Employees Association last week to say a search warrant for Mrs Johnston's house was delayed, according to the newspaper report. ‘It was not allowed to progress in a normal fashion, the search warrant WAS delayed because of the pending [November 2008 presidential] election and the [...] Drug Unit [...] and the case officer were not the ones calling the shots.’” This Mrs Johnston is the mother of Levi Johnston, who is notoriously engaged to Mrs Palin's daughter, Bristol. She “was arrested on Dec 18 and on Monday pleaded not guilty to six counts of possessing and selling OxyContin”. It would have been so entertaining to have this bunch running around the White House.

“Rands” makes a good case for “Dropbox”, an online, quite automated, versioning storage system. This is worth keeping an eye on, although I think I'll stick with git and servers that I control for now. More Dropbox love by David Weintraub.
2008-12-12 Bad science: It's not what the papers say, it's what they don't
If you are following the execrable antics of the anti-vaccination frauds such as Gary Null, you will be fascinated by Ben Goldacre’s article in The Guardian:
On Tuesday the Telegraph, the Independent, the Mirror, the Express, the Mail, and the Metro all reported that a coroner was hearing the case of a toddler who died after receiving the MMR vaccine, which the parents blamed for their loss. Toddler 'died after MMR jab' (Metro), 'Healthy' baby died after MMR jab (Independent), you know the headlines by now. On Thursday the coroner announced his verdict: the vaccine played no part in this child's death. So far, of the papers above, only the Telegraph has had the decency to cover the outcome. The Independent, the Mirror, the Express, the Mail, and the Metro have all decided that their readers are better off not knowing.

Antonio Cangiano from math-blog provides a well-organized summary introduction to the use of Maxima, a free, open-source symbolic mathematics program that runs on OS X, linux, and, I'm sure, elsewhere. I've used Maxima and it is an excellent and serious tool, similar to the Macsyma of long ago.
2008-12-09 The Importance of Mathematics
Another discovery courtesy of the math-blog: a video of a superb lecture by the mathematician Timothy Gowers.
