Bram's proposal

There is nothing fundamentally wrong with a solar powered steam turbine, although Bram's description needs a pump between condenser and the boiler. Pressure in the boiler is higher than in condenser (this is why the turbine turns), and so a water pump is needed to counteract it. The pump can be mechanically driven by the turbine. The system looks like a perpetum-mobile, but it isn't, because it's not closed: energy is delivered into it by the Sun radiation.

A note regarding depressurizing the boiler is that any thermal cycle machine's efficiency is directly proportional to the temperature gradient. The temperature of the condenser in Bram's case cannot be lower than the temperature of the atmosphere, therefore it is advantageous to raise the temperature of the boiler (I think this is the primary reason why a plant's turbine is driven by superheated steam at 200 degrees Centigrade or more).

The DSL monopoly (in the U.S.)

For the benefit of deekayen, the following ways around the DSL monopoly exist:

  • Cable modem. You have to put up with filtering. $45/mo.
  • DirecWay. You must use a Windows based router/NAT. Satelline latencies. $75/mo if you're lucky.
  • Fixed wireless. In my locale, the fixed wireless provider WAC.com is retreating. I reckon they did not gather a critical mass and cannot continue operating at $40/mo. But I'm told it is booming in places like Santa Rosa, CA.
  • Community and government networks, often wireless. You have to be creative to tap into them.

Writing to senators and such is in vain. Find your local wireless provider and sign up instead, even if it costs more than DSL.

I have a different view from Pierre about the kernel drift of OLS. That view does not involve big companies like IBM or kernel being any "cooler". Simply put, userland is incomparably larger than the kernel, and it's well partitioned into applications. Therefore, userland hackers gravitate towards conventions where they can meet like-minded people, naturally. If one were a GNOME hacker who can only visit one conference in a year, would you go to OLS or GUADEC? Likewise, Andrew Hutton set out to create a gcc conference (OGS?). As application people are attracted to their own venues, kernel expands to fill OLS. Their program committee turns down competent papers every year, because they have no space.

What's up with rillian's Ghostscript? Not a peep from Raph as yet.

The Iraq campaign somehow made a lot of people much worse and disgusting than they were, to what Advogato recentlog is a bright evidence. A member wrote: "George Bush and his loathesome band of war criminals [...] lawlessly ravage Iraq, causing death and destruction in their wake." The guy knows about interogation with acid baths, dissidents in wood shredders, and refugees set on fire, but thinks it's all right. Putting an end to all that is "loathsome" and "criminal" to him.

[== Update 3/28:

Immediately, raph replied with the following.

    Zaitcev: passions are running high, on all sides. I ask you (and all Advogato posters) to be respectful of other people's opinions. There is no question that Bush is responsible for death and destruction on a large scale. Whether it's legal according to international law is one question. Whether it improves the situation for the Iraqi people is another (I honestly hope it does). Reasonable people can, and do, differ on these questions.
This is unbelievable. He is completely captured by the leftist propaganda and lies, but still pretends to "be nice".

I think it was a great shame that he was arrested for a non-violent protest. Apparently it did nothing to help his political and citizen's thinking. Remember the old saying that a liberal is a conservative who was arrested and a conservative is a liberal who was mugged?

Currently, Raph started to try to squeeze or off-load topics unrelated to free software manually, as his message above suggests. He also attempts to set an example with "the other blog", which is commendabe, but fails to mask the failure of his own creation, the trust web and metric, to deal with unwanted posters. At least the failure so far. One is to hope that he is thinking about a solution.

I decided to take his hint and leave, but let's see what he is going to do about rabid ravings of mglazer (obviously, rabid ravings of leftists are of no concern to him, even though he pretends to hand the niceness evenly left and right).

Funnily how the David Dawes made the ejection of Keith Packard from XFree86 to coincide with the begining of the next battle in the war with Islamists. Coincidence, no doublt.

I just wasted a perfectly good week on an s390x bug in recent kernels. If a 64 bit program executes a 31 bit program, load_elf_binary() uses TASK_UNMAPPED_BASE before it sets the mode bit, but on some platforms the former uses the latter. So, the /etc/ld.so cannot mmap anything. A whole week!!

Welcome, Riel

Rik van Riel posted his first message to internal lists today, and is getting settled at his new place, which is to say, in the same team with me (centered around Boston). I am pretty sure he'll like it here. This is very cool. We attract all the very best people, and I hope that some of their smarts rubs off on me.

Mainframe

I got my target kernel compiled, but it is unable to deactivate the comparator timer, and loops, doing about 660,000 timer interrupts per second. Mystery.

[Update: No sooner I post the entry, Martin S. (the arch maintainer) posts a fix]

Yesteday, I stepped off the terminal for an evening stroll, and was greeted by the following message upon return:

RPIMGR046T User ID ETPRPTN access has been revoked.
LOGOFF AT 22:13:02 CST TUESDAY 03/04/03 BY SYSTEM

Since my patches and trees were on destroyed minidisks, two days of work were wasted. Oh well. Examination of mail archives revealed that I was warned with a single word: "TSSIA" (actually, the angel of death misspelled it as "TSISA"). OK, YA TLA.

Today, I exercised taking a certain point actoss, in particular to mharris, with very little success. The nature of the point is not important, but for the record it dealt with a balance between source compability, binary compatibility, and pace of development for a project. Apparently, my wording made Mike to latch on the essay framing instead of the point iself, repeatedly. I need to take a writing class. Or start drinking beer and discuss development in bars.

I just realized that I spent a whole week (with weekend) trying to get IBM BladeCenter to work with obsolete kernels. Feeling a little numb now.

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
