Caoimhe Butterly

Guardian: Courage under fire. No matter what you think about what’s going on in Israel and Palestine, Caoimhe, and the other international observers, require your support:

Friday was a very close call. Caoimhe was shot in the left thigh as she stood in between a firing IDF tank and three young boys in the street. I spoke to her on the phone shortly after the attack as she lay in her hospital bed. She explained that she had been trying to persuade the IDF, after they shot dead a nine-year-old boy, to stop shooting at the children. They had told her to get out of their way or they would shoot her. It was while she was clearing the children off the streets that she was shot. She is sure she was a direct target; the tank was close by, the soldier pointed his gun at her and fired, and continued to do so as she crawled to an alleyway for shelter.

I asked an IDF spokesman for his explanation. ‘We are in the middle of a war and we cannot be responsible for the safety of anyone who has not been coordinated by the IDF to be in the occupied territories right now. While we do not want innocent Palestinians to suffer, or internationals to get hurt, we are trying to ensure the safety of the Israelis and we will not tolerate internationals interfering with IDF operations. It is not the job of internationals to stand in the line of fire, unless they are the son of God, but he hasn’t come yet.’

The case of the 500-mile email. (fwd)

A great tale of systems wierdness, via 0xdeadbeef:

‘We’re having a problem sending email out of the department.’ ‘What’s the problem?’ I asked. ‘We can’t send mail more than 500 miles,’ the chairman explained.

Here’s a problem that *sounded* impossible… I almost regret posting the story to a wide audience, because it makes a great tale over drinks at a conference. :-) The story is slightly altered in order to protect the guilty, elide over irrelevant and boring details, and generally make the whole thing more entertaining.

I was working in a job running the campus email system some years ago when I got a call from the chairman of the statistics department.

“We’re having a problem sending email out of the department.”

“What’s the problem?” I asked.

“We can’t send mail more than 500 miles,” the chairman explained.

I choked on my latte. “Come again?”

“We can’t send mail farther than 500 miles from here,” he repeated. “A little bit more, actually. Call it 520 miles. But no farther.”

“Um… Email really doesn’t work that way, generally,” I said, trying to keep panic out of my voice. One doesn’t display panic when speaking to a department chairman, even of a relatively impoverished department like statistics. “What makes you think you can’t send mail more than 500 miles?”

“It’s not what I *think*,” the chairman replied testily. “You see, when we first noticed this happening, a few days ago–”

“You waited a few DAYS?” I interrupted, a tremor tinging my voice. “And you couldn’t send email this whole time?”

“We could send email. Just not more than–”

“–500 miles, yes,” I finished for him, “I got that. But why didn’t you call earlier?”

“Well, we hadn’t collected enough data to be sure of what was going on until just now.” Right. This is the chairman of *statistics*. “Anyway, I asked one of the geostatisticians to look into it–”

“Geostatisticians…”

“–yes, and she’s produced a map showing the radius within which we can send email to be slightly more than 500 miles. There are a number of destinations within that radius that we can’t reach, either, or reach sporadically, but we can never email farther than this radius.”

“I see,” I said, and put my head in my hands. “When did this start? A few days ago, you said, but did anything change in your systems at that time?”

“Well, the consultant came in and patched our server and rebooted it. But I called him, and he said he didn’t touch the mail system.”

“Okay, let me take a look, and I’ll call you back,” I said, scarcely believing that I was playing along. It wasn’t April Fool’s Day. I tried to remember if someone owed me a practical joke.

I logged into their department’s server, and sent a few test mails. This was in the Research Triangle of North Carolina, and a test mail to my own account was delivered without a hitch. Ditto for one sent to Richmond, and Atlanta, and Washington. Another to Princeton (400 miles) worked.

But then I tried to send an email to Memphis (600 miles). It failed. Boston, failed. Detroit, failed. I got out my address book and started trying to narrow this down. New York (420 miles) worked, but Providence (580 miles) failed.

I was beginning to wonder if I had lost my sanity. I tried emailing a friend who lived in North Carolina, but whose ISP was in Seattle. Thankfully, it failed. If the problem had had to do with the geography of the human recipient and not his mail server, I think I would have broken down in tears.

Having established that — unbelievably — the problem as reported was true, and repeatable, I took a look at the sendmail.cf file. It looked fairly normal. In fact, it looked familiar.

I diffed it against the sendmail.cf in my home directory. It hadn’t been altered — it was a sendmail.cf I had written. And I was fairly certain I hadn’t enabled the “FAIL_MAIL_OVER_500_MILES” option. At a loss, I telnetted into the SMTP port. The server happily responded with a SunOS sendmail banner.

Wait a minute… a SunOS sendmail banner? At the time, Sun was still shipping Sendmail 5 with its operating system, even though Sendmail 8 was fairly mature. Being a good system administrator, I had standardized on Sendmail 8. And also being a good system administrator, I had written a sendmail.cf that used the nice long self-documenting option and variable names available in Sendmail 8 rather than the cryptic punctuation-mark codes that had been used in Sendmail 5.

The pieces fell into place, all at once, and I again choked on the dregs of my now-cold latte. When the consultant had “patched the server,” he had apparently upgraded the version of SunOS, and in so doing *downgraded* Sendmail. The upgrade helpfully left the sendmail.cf alone, even though it was now the wrong version.

It so happens that Sendmail 5 — at least, the version that Sun shipped, which had some tweaks — could deal with the Sendmail 8 sendmail.cf, as most of the rules had at that point remained unaltered. But the new long configuration options — those it saw as junk, and skipped. And the sendmail binary had no defaults compiled in for most of these, so, finding no suitable settings in the sendmail.cf file, they were set to zero.

One of the settings that was set to zero was the timeout to connect to the remote SMTP server. Some experimentation established that on this particular machine with its typical load, a zero timeout would abort a connect call in slightly over three milliseconds.

An odd feature of our campus network at the time was that it was 100% switched. An outgoing packet wouldn’t incur a router delay until hitting the POP and reaching a router on the far side. So time to connect to a lightly-loaded remote host on a nearby network would actually largely be governed by the speed of light distance to the destination rather than by incidental router delays.

Feeling slightly giddy, I typed into my shell:

$ units 1311 units, 63 prefixes

You have: 3 millilightseconds You want: miles

  • 558.84719 / 0.0017893979

“500 miles, or a little bit more.”

Ireland vs Spam

According to the Minister for Communications, Marine and Natural Resources, Mr. D. Ahern, Ireland will “transpose into Irish law the requirements of European Parliament and Council Directive 2002/58/EC concerning the processing of personal data and the protection of privacy in the electronic communications sector” before the end of 2003.

It will be nice to be able to point to the law, eventually — for what that’s worth. Since most spammers are USian, relaying via other countries, actually acting on the law will not be quite so simple. But it will be an improvement.

Hashish ‘fell on to back of army lorry’. “Spain’s defence ministry is still at a loss to explain how three-quarters of a tonne of hashish had turned up in an army truck. … ‘Anybody could have put the toxic substance there,’ said the defence minister”.

Hashish ‘fell on to back of army lorry’

Giles Tremlett in Madrid Tuesday November 26, 2002

It is a matter, you might say, that is shrouded in dense, aromatic smoke – Spain’s defence ministry is still at a loss to explain how three-quarters of a tonne of hashish had turned up in an army truck in the country’s north African enclave of Melilla.

Embarrassed officials tried to claim that the troops it has permanently stationed in north Africa would never have succumbed to the temptation of smuggling the region’s most important cash crop across the Mediterranean.

The high-quality Moroccan hashish, almost certainly produced in the nearby Rif mountains, was found by police sniffer dogs in the port of Melilla as the truck waited to be shipped to Almeria.

“Anybody could have put the toxic substance there,” said the defence minister, Federico Trillo, after explaining that the truck had been parked, unattended, in Melilla’s port for about two days.

Local police disagreed. The truck had only been parked there for a few hours, they said. They suggested that the khaki kit bags stuffed full of shrink-wrapped dope could only have come from within the Spanish armed forces.

The questioning of eight uniformed suspects has shed no further light on the case and opposition politicians have called for a full explanation from Mr Trillo.

The drugs bust has done little to improve ties with nearby Morocco, which claims Melilla as its own and is constantly accused by Madrid of turning a blind eye to hashish-smuggling.

The find also came at a troubled time for the newly professional Spanish armed forces, which are failing to attract recruits and retain their aircraft: they lost their only trial version of the £50m Eurofighter in an accident last week.

Mr Trillo, a proud military man and stern Catholic conservative, hoped the standing of the armed forces had improved after special forces ejected six poorly armed Moroccan gendarmes from the Parsley islet over the summer.

But now both he and the armed services are being ruthlessly lampoonedby, among others The Puppet Show News, Spain’s equivalent of Spitting Image.

Mr Trillo, a member of the strict Opus Dei Catholic lay order, is routinely portrayed as a uniformed pothead whose favourite pastime is getting stoned with the mascot of the Spanish Legion, a little white goat called Blanquita.

As both he and Blanquita mourned the lost Eurofighter by lighting up a giant joint at the weekend, the defence minister declared: “It’s the only way to fly.”

diary of an autopsy

Sliced liver, anyone? “The first public autopsy in Britain for 170 years brought back vivid memories of medical school – and an acute sense of hunger – for the Guardian’s junior doctor Michael Foxton.”

“The process of dismemberment is a deeply weird and dysphoric experience, and it is a dangerous border to cross. I remember the first time I had to do it, as a medical student in an operating theatre. It was a man with stomach cancer, who I had been talking to on the ward the morning before his operation. When the surgeon brought his knife down to make the first cut on his belly, it was everything I could do to stop myself reaching out and grabbing his hand to stop him. Doctors have to cross that line. We have to separate the thinking, smiling, family man from the clinical material. If I hadn’t done that I couldn’t possibly cut a hole and force a huge chest drain tube a centimetre across into a writhing patient on a respiratory ward at three in the morning, without going mad.”

who, me?

now that’s a great name tag:

‘these children are the main entree for dinner’

I just dug up this classic piece of lunacy from the Montauk UFO contingent. Highly recommended if you like reading this kind of wierdness…

DA: Hmmm. Who do these aliens eat?

AC: They specifically like young human children, that haven’t been contaminated like adults. Well, there is a gentleman out giving a lot of information from a source he gets it from, and he says that there is an incredible number of children snatched in this country.

DA: Over 200,000 each year.

AC: And that these children are the main entree for dinner.

yum yum!

A Prayer Before Dying

Wired – A Prayer Before Dying: “the astonishing story of a doctor who subjected faith to the rigors of science – and then became a test subject herself”, by Po Bronson:

In July 1995, back when AIDS was still a death sentence, psychiatrist Elisabeth Targ and her co-researchers enrolled 20 patients with advanced AIDS in a randomized, double-blind pilot study at the UC San Francisco Medical Center. All patients received standard care, but psychic healers prayed for the 10 in the treatment group. The healers lived an average of 1,500 miles away from the patients. None of the patients knew which group they had been randomly assigned to, and thus whether they were being prayed for. During the six-month study, four of the patients died
  • a typical mortality rate. When the data was unblinded, the researchers learned that the four who had died were in the control group. All 10 who were prayed for were still alive.

But read on — it’s not as simple as all that…

FTC’s ”Spam Harvest”

FTC: “Spam Harvest” Results Reap Help for Consumers Trying To Avoid Spam. Some good prosecutions (yay!):

The FTC alleged that NetSource One and James R. Haddaway, operating as WorldRemove, used spam and the Internet to sell a service they claimed would reduce or eliminate spam from consumers’ e-mail. The claims were false. In fact, using an undercover account to test the claims, the FTC found it received more spam after signing up for the service. The agency charged the defendants with violations of the FTC Act.

Plus some good official studies to back up our own, unscientific research:

In an effort to determine what online activities place consumers at risk for receiving spam, Northeast Netforce investigators seeded 175 different locations on the Internet with 250 new, undercover e-mail addresses and monitored the addresses for six weeks. The sites included chat rooms, newsgroups, Web pages, free personal Web-page services, message boards and e-mail service directories. One hundred percent of the e-mail addresses posted in chat rooms received spam; the first received spam only eight minutes after the address was posted. Eighty-six percent of the e-mail addresses posted at newsgroups and Web pages received spam; as did 50 percent of addresses at free personal Web page services; 27 percent from message board postings; and nine percent of e-mail service directories.

Plus, the lie of “targeting”:

Spam Harvest partners also found that the type of spam received was not related to the sites where the e-mail addresses were posted. For example, e-mail addresses posted to children’s newsgroups received a large amount of adult content and work-at-home spam.

WSJ: For Bulk E-Mailer, Pestering Millions Offers Path to Profit.

I’m just trying to make a living like everyone else, says Ms. Betterly. … (she) quickly discovered that she could make a profit if she got as few as 100 responses for every 10 million messages sent for a client, and she figures her income will be $200,000 this year.

(Untitled)

Some folks reckon that mailservers should have reverse DNS — in other words, that the SMTP server should have a fully-valid forward-to-reverse mapping for its address, to cut down on spam and forgeries. All well and good.

Some other folks reckon that filtering on it is therefore a good way to cut down on spam.

It’s a nice idea, apart from 2 things:

  • filtering based on this suffers the same problem some DNSBLs have: a false positive hurts the user, rather than the person who is at fault; also the user is virtually powerless to fix it.

  • the correlation between spam and missing reverse DNS is no longer as strong as it used to be, as far as I can tell; spammers know they should pick a relay or proxy with a reverse DNS entry to get through filters, and as it becomes a requirement for relaying in general, more hosts have this anyway (regardless of exploitability or not).

recommended: Leaky Abstractions

Joel on Software now features a great new article on what he calls “Leaky Abstractions”. Some snippets:

  • Even though network libraries like NFS and SMB let you treat files on remote machines “as if” they were local, sometimes the connection becomes very slow or goes down, and the file stops acting like it was local, and as a programmer you have to write code to deal with this. The abstraction of “remote file is the same as local file” leaks. …

(jm: the ‘transparent does not always mean good’ problem)

  • Something as simple as iterating over a large two-dimensional array can have radically different performance if you do it horizontally rather than vertically, depending on the “grain of the wood” — one direction may result in vastly more page faults than the other direction, and page faults are slow. Even assembly programmers are supposed to be allowed to pretend that they have a big flat address space, but virtual memory means it’s really just an abstraction, which leaks when there’s a page fault and certain memory fetches take way more many nanoseconds than other memory fetches.

(jm: the ‘why objects are not always the way to do it’ problem)

And finally, he ends with a killer:

Ten years ago, we might have imagined that new programming paradigms would have made programming easier by now. Indeed, the abstractions we’ve created over the years do allow us to deal with new orders of complexity in software development that we didn’t have to deal with ten or fifteen years ago, like GUI programming and network programming. And while these great tools, like modern OO forms-based languages, let us get a lot of work done incredibly quickly, suddenly one day we need to figure out a problem where the abstraction leaked, and it takes 2 weeks. And when you need to hire a programmer to do mostly VB programming, it’s not good enough to hire a VB programmer, because they will get completely stuck in tar every time the VB abstraction leaks.

Well said! Read the article!

ICAP

ICAP-server, an (imaginatively-named) daemon which implements ICAP. This seems to be a transcoding proxy server; in other words, it will convert HTML content on the fly, while you browse.

ICAP itself seems to be a protocol for rewriting HTTP responses; in other words, it allows a proxy server to include a small snippet of ICAP client code, and call out to an ICAP server to do the rewriting. Nifty.

Sounds like this could be very handy for low-bandwidth situations; use ICAP to “downshift” web pages into low-bandwidth versions. For example, banner ads can be trimmed out, heavy images converted to small, low-quality JPEGs, etc. One to watch (or help out with).

Ericsson used to have a commercial product which did something similar, but I can’t find it now…

Trinity College, home of the Jedi

Trinity College, Dublin is currently embroiled in a minor kerfuffle with Lucasfilm over “an uncanny resemblance between the 18th-century Long Room Library at Trinity, and the “Jedi Archives” in the latest episode of the “Star Wars” epic.” (Reuters)

The resemblance really is uncanny — I noticed it myself on watching the movie, but assumed there must have been a hundred similar libraries around the world. Sounds like Trinity think there’s only one after all. Given that it’s Trinity, maybe they’re right.

Compare: the Jedi archives vs. the Long Room.

the Anti-Telemarketing EGBG Counter-Script

the Anti-Telemarketing EGBG Counter-Script:

Telemarketers make use of a telescript – a guideline for a telephone conversation. This script creates an imbalance in the conversation between the marketer and the consumer. It is this imbalance, most of all, that makes telemarketing successful. The EGBG Counterscript attempts to redress that balance.

Half of the coolness here is the excellent, form/script-based design. Well suitable for printing out and sticking to the wall beside the ‘phone…

The Da Ming Hun Yi Tu

I’ve been reading an article in Edge Magazine, How To Get Rich, by Jared Diamond (author of Guns, Germs and Steel). He investigates more deeply into the differences between cultures, and the effect this has had on their history and dominance, as he did in GG+S; this time with economic might in mind.

For example, he notes that the Chinese, in the middle ages, were a sea-faring nation of astounding skill, exploring most of the coasts of Asia and Africa for trade. They were on the verge of rounding the Cape of Good Hope (and, in the words of Diamond, “colonising Europe” ;) when a new emperor with an anti-Navy bias took power, and recalled them. Since the entirety of China’s empire was ruled solely by one power, the emperor, that was that. (Compare with Columbus, who could “shop around” the many superpowers of Europe until his trip across the Atlantic was funded.)

Then, this morning, a pertinent link arrived via Kyle Moffat of forteana: an ancient Chinese map of Africa is now on show in Cape Town (BBC).

The Chinese map, covering more than 17 square metres, was produced in silk. It is thought to be a copy of a map sculpted into rock 20 or 30 years earlier. …

The Da Ming Hun Yi Tu, or Amalgamated Map of the Great Ming Empire, is a unique snapshot of history. Created in China in 1389, and clearly showing the shape of Africa, more than 100 years before Western explorers and map-makers reached the continent.

BTW, worth noting that I came across the Diamond article from a link in Clay Shirky’s guest-blog at Boing Boing. Clay, as usual, is throwing up lots of reading material, which I just don’t have time to read ;) so I’m syncing it all to my Palm with Sitescooper. Come on Xerox, where’s that electronic paper!?

Googlism, what is the web?

  • the web is like canada

  • the web is dedicated to breathing life into women’s

  • the web is crippling

  • the web is ruined and i ruined it self

OK, what about the internet?

  • the internet is falling

  • the internet is not printed on paper

  • the internet is like is like a penis

  • the internet is no substitute

And Ireland?

  • ireland is dedicated entirely to development aid

  • ireland is at an end

  • ireland is again the “dirty man” of europe when it comes to

  • ireland is not disneyland

  • ireland is british (what?!)

  • ireland is looking for a german inhouse translator

Incredible stuff. Sounds like they could do with the cool innovation recently introduced here — the “dob-a-dangerous-driver” line (1).

Let’s say you’re doing what a friend of mine did a few months ago: crossing the road, with your kid in a buggy, at a pedestrian crossing, with the lights in your favour — then a speeding driver breaks the lights at top speed and nearly totals the pair of you.

This great innovation then allows you to whip out your mobile phone (hey, this is europe, everyone has one (2)), and immediately report the car’s registration number — and 2 weeks later he receives a fine! Hey presto, instant justice. (3)

And in the last week, they’ve introduced penalty points for bad driving; 12 points and you lose your license. Things can only get better — for the pedestrians that is, at least. ;)

BBC front page for Ireland Offline

man, this is sweet! BBC front page coverage for Ireland Offline

“Eircom has cited congestion of the network and not enough demand as the arguments against unmetered (internet access),” said Mr (Dave) Long (IO chairman).

BT-owned ESAT is just one of the telecom operators challenging Eircom to offer a wholesale unmetered product.

“There is huge pent-up demand and our ears are sore from listening to our own customers. For Eircom to say there is no demand is condescending and naive,” said (Una) McGirr (of ESAT BT).

Maybe what Eircom mean, is that there’s not enough demand to outweigh the unfeasibly large revenues they make from metered internet calls…
