Antarctic Whaling Season Begins

December 20th, 2008

The captain of the Sea Shepherd, Paul Watson.
JAPAN’S Antarctic whaling season faces the prospect of severe disruption, with the discovery of the fleet by the hardline anti-whaling activists of Sea Shepherd.

Japan’s fisheries agency and justice ministry have announced that anyone forcibly trying to disrupt the hunt will be detained by the whalers and handed over to the Japanese Coast Guard.

The LA Times blog suggests that Australia’s opposition to whaling is primarily economic.  I do not think that is correct.

Australia and New Zealand have spoken out against the hunts, largely because whale-watching is a vital industry in those countries and killing whales that frequent their waters is bad for business.

Greenpeace are likely to turn up this year too.

Minimise latency due to swapping:

# echo 10 > /proc/sys/vm/swappiness

Maximise available memory by swapping:

# echo 100 > /proc/sys/vm/swappiness

The Fedora 8 (Werewolf) default appears to be 60.

Austin Urban Tree Options

December 19th, 2008

TreeFolks are offering us a free tree, in return for taking good care of it, as part of the NeighborWoods program.

Mexican White Oak

40 ft high, full sun, no bloom, drought tolerant, evergreen, fast growth, oak wilt resistant.

Mexican White Oak

  • Plantfiles
    There is a beautiful specimen of this tree near my home in south Austin (Texas). It is about 45 feet tall and very healthy. That particular tree is about 17 years old I am told. Based on this, I planted two in my yard in January, 2007. 13 months later they are doing just fine.
  • Shademaker trees
    An underutilized, highly adaptable shade tree that will tolerate urban planting conditions.
  • wildflower.org
    This species is widespread in Mexico and found in a few west Texas canyons. It is a relatively fast growing oak, and practically evergreen in Austin. It is more resistant to oak wilt and other diseases and pests than other oaks.
  • Texas Forest Service
    Leathery leaves come in many different shapes and remain on twigs into winter.

Bur Oak

80ft high, acorns, deciduous, slow growing, drought resistant, state tree of Iowa.

Quercus macrocarpa

  • wikipedia.org
    Large deciduous tree growing up to 30 m (100 ft), rarely 37 m (120 ft), in height, and is one the most massive oaks with a trunk diameter of up to 3 m (10 ft). It is one of slowest-growing oaks, with growth rate of 30 cm (1 ft) per year when young. A 20-year-old tree will be about 6 m (20 ft) tall. It commonly lives to be 200 to 300 years old, and may become significantly older. The bark is a medium gray and somewhat rugged.
  • grownative.org
    A slow-growing, long-lived impressive tree with the largest leaves and acorns of all the oaks. Leaves turn brown or light yellow in the fall and remain on the plant through winter. Trees are weakly pyramidal when young then develop a massive trunk and broad crown with strong branches.
  • USDA Forest Service
    Bur oaks bear seed up to an age of 400 years, older than reported for any other American oak. The minimum seed-bearing age is about 35 years, and the optimum is 75 to 150 years (5,16). Good seed crops occur every 2 to 3 years, with no crops or light crops in intervening years. The acorns are disseminated by gravity, by squirrels, and to a limited extent by water.

Chinquapin Oak

90ft tall, deciduous, full sun, drought tolerant, good shade, acorns, disease and pest resistant.Chinkapin Oak

  • wikipedia.org
    A deciduous tree reaching 30 m tall (exceptionally up to 50 m), with a rounded crown and thin, scaly or flaky bark on the trunk. The name comes from the resemblance of the leaves to those of a chestnut or chinkapin, although they also greatly resemble the chestnut oak or swamp chestnut oak; coarsely toothed, 5-15 cm long and 4-8 cm broad.
  • Texas A&M
    A good-looking medium to large shade tree suitable for use in much of Texas. Its unique saw-tooth leaves, which resemble those of the chinquapin tree found in the eastern United States, are rich green, turning yellow to bronze in the fall. It grows in the wild on well-drained bottomland soils and on limestone hills near water. It’s adaptable to a range of soils and exposures. It’s moderate to fast-growing and develops an open rounded crown as it ages.
  • Texas Superstar
    Although this member of the beech family (Fagaceae) can obtain a larger size in the eastern U.S., it usually grows to be a handsome medium size shade tree in the 30′ to 50′ tall range in many of our urban or suburban Texas landscapes. Thus, chinkapin oak remains more in scale with residential plantings than some larger shade trees.

Elm

100 ft tall, deciduous, susceptible to Dutch elm disease, disease-resistant cultivars available.

American Elm

  • wikipedia.org
    There are approximately 30 to 40 species of elm; the ambiguity in number is a result of difficult species delimitations in elms, owing to the ease of hybridization between them and the development of local seed-sterile vegetatively-propagated microspecies in some areas, mainly in the field elm group. Rackham describes Ulmus as the most difficult critical genus in the entire British flora. Eight species are endemic to North America, and a smaller number to Europe; the greatest diversity is found in China.

No stricmp on Linux?

December 18th, 2008

I’ve been using stricmp() for a long long time but this is the first time I found there’s no stricmp() in Linux.

Maintaining cross-portability of C code can be frustrated by the occasional mismatch of Win32 and POSIX APIs.  On Linux there is no stricmp, but there is strncasecmp reportedly conforming to 4.4BSD and POSIX.1-2001.

In some places stricmp is reported to be ANSI, but I didn’t find any mention of it in ISO/IEC 9899:TC2 the C99 specification.  It just seems that Microsoft added it as a vendor extension, but mistakenly documented it as being ANSI and/or POSIX.

A recommended solution is to #define strncasecmp stricmp for Windows builds.

Good Time for Switching to Firefox

Serious Internet Explorer flaw not fixed

The flaw lets criminals commandeer victims’ machines merely by tricking them into visiting websites tainted with malicious programming code. As many as 10,000 sites have been compromised since last week to exploit the browser flaw, according to antivirus software maker Trend Micro.

Microsoft said it is investigating the flaw and is considering fixing it through an emergency software patch outside of its normal monthly updates, but declined further comment. The company is telling users to employ a series of complicated workarounds to minimize the threat.

Freedom of religion denied to non-religous in Australia

December 14th, 2008

As reported in The Age today, plans for humanist philosophy classes to be available as an alternative to Christian, Muslim, Judaism, Buddhism and Baha’i religions.

Religion in schools to go God-free

Victorian Humanist Society president Stephen Stuart said: “Atheistical parents will be pleased to hear that humanistic courses of ethics will soon be available in some state schools.”

However, Access Ministries and Salt Shakers don’t seem to appreciate the intrusion on their turf:

Fundamentalist Christian group the Salt Shakers panned the idea of humanists being given religious education class time. Research director Jenny Stokes said: “If you go there, where do you stop? What about witchcraft or Satanism?  If you accredit humanism, then those things would have an equal claim to be taught in schools.”

So humanism equals satanism and witchcraft?  Yeah right.

Ms Stokes said humanists could not expect to have it both ways. “It doesn’t make sense because they proclaim themselves not to be a religion,” she said.  Religious instruction in state schools should be Christian because “basically we are a Christian nation”, she said.

Perhaps Ms Stokes should be informed that humanism is not a religion by definition, not by proclamation.  But, the real point of their opposition is maintaining the illusion of a Christian monopoly on matters ethical and moral.

At best that amounts to willfull ignorance.  At worst it represents repression of the non-religous.

Follow up in the Letters to The Age:

The anti-God crusade

THE humanist/atheist brigade will soon have the right to present its anti-God/anti-Christian doctrine in the religious education time slot in state schools.

I thought it already had its allotted sessions in the school science curriculum, where its evolutionist dogma is so forcefully entrenched that it prevents any other viewpoint from even being considered, let alone discussed.
