OK, so who's got the administrator password for this (and related) lists? Some antispam configuration is required. I'm interested in seeing this project go forward. Any taker for coding? I guess this will be my next task after XCVB 1.0. [ François-René ÐVB Rideau | Reflection&Cybernethics | http://fare.tunes.org ] I have many lucky numbers: 45, 357, 9, etc etc etc. but 911 is NOT one of them - I440r

[erlang-in-lisp-devel] Is Israel a Democracy? -- The problem with intellectually insecure whites -- Should Christians Support Israeli Terrorism in Gaza?
by Lawrence Auster 23 Jan '09

23 Jan '09

The Jewish State of Israel has no constitution, nor does it name its borders. Israel's hidden constitution is Judaism. Israel's undeclared borders range from the Nile to the Euphrates rivers. Israel's desired jurisdiction extends over the entire Earth. It could not be more clear that the Jewish State follows a foreign policy which obeys Jewish Law as iterated in the Hebrew Bible, the Talmud, Maimonedes, the Cabalah, and the many commentaries and refinements of same. The Jews are genociding the native inhabitants of Palestine, just as their religion advises, and because their religion teaches them to do so. They treat non-Jews as if non-humans, just as their religion requires them to do. They make perpetual war on every nation on Earth, just as their genocidal Jewish God has instructed. The Jews of Israel are simply being Jews. Jews are an existential threat to the human race. Israel contains one third of the Jews of the World. It is not some aberration of the Jewish spirit, but the condensation and concentration of the perverse Jewish mentality, which malady also pervades the remaining two thirds of Jewry, who almost unanimously support the Jewish State, and who certainly do unanimously support the Jewish People and its consistent and constant crimes against the human race. Israel is Jewry and the danger of Israel is the danger of the Jewish People to all others, as the Jews have demonstrated each and every day of their existence. The Jews, the entire Jewish People of 15 million, will not relent until they have wiped out all non-Jews in "Greater Israel". They will not stop destroying all other cultures, nations, religions, ethnicities, races, competition, etc. until they are either stopped, or succeed in their ancient quest to destroy the human race. What Israel is doing is not some reaction to outside forces, nor was the formation of Israel a response to the Holocaust. Israel is simply following the plan laid out in the Jews' religious texts. The Jews have openly planned to take Palestine and genocide the native population of Palestine for some 2,500 years before the Holocaust. The Jews have openly complained that "anti-Semitism" is a threat that gives them the right to genocide the Palestinians, not merely since the advent of Nazism, but for some 2,500 years. The Jewish religion is the Constitution of the Jewish State of Israel, and, to a greater or lesser extent, the constitution of the nature of every Jew alive. The borders of Israel are the range the Jew roams over the entire World. The perverse Jewish mentality is inbred by a Jew's exposure to his parents and to his community. Judaism passes in the spit and slobber of Jewish mother telling her Jewish child that he is a "Jew", as much as Judaism passes in the poison and pain of a Talmudic tractate. The secular Jews did not suddenly come to life after the Enlightenment and the Jewish Reformation a body of vampires that appeared ex nihilo, in vacuo, mostly atheistical and undetached from formally practiced Judaism. Judaism is the Jew. It is a mindset that transcends and supercedes religion. It is a belief set, a way of life, a perception of one's self and one's relation to the World that makes a Jew, a Jew, and a danger to all of humanity. In fact, the religious shell of Judaism is like the stretched and infected skin of a lycanthropic pustule. When you lance it to cure the infection, the virus only becomes more contagious and spills directly on the non-Jew. The secular Jew is a deliberate product of the hyper-religious Jew, a monster created out of the hewed corpses of the fanatically religious Jew, a Golem which is conjured up to enter the World of the non-Jew and poison its blood, and boil its brain with a rabid lunacy that bites and spreads, until the infected community feeds on itself and fills the fields with rotting bloating bodies, where once human beings tilled the soil and tended to their families. The religious Jew created the secular Jew as an army of Esthers who seduce with open thighs, broad smiles, and a Siren call that lures in the non-Jew to cast his skull upon the jagged rocks and color the seas with his blood, sickened and blinded by the venereal disease of Judaism in secular form. Israel is not a secular democracy. It is a religious mockery. It is a rabid bat flying to the ends of the Earth, to end the Earth. No one will be free nor safe until the disease is quarantined and dies out. Source: http://www.ziopedia.org/articles/israel/how_can_israel_claim_to_be_a_%27dem… -------------------- The problem with intellectually insecure whites By Kevin MacDonald January 19, 2009 America will soon have a white minority. This is a much desired state of affairs for the hostile elites who hold political power and shape public opinion. But it certainly creates some management issues � at least in the long run. After all, it�s difficult to come up with an historical example of a nation with a solid ethnic majority (90% white in 1950) that has voluntarily decided to cede political and cultural power. Such transformations are typically accomplished by military invasions, great battles, and untold suffering. And it�s not as if everyone is doing it. Only Western nations view their own demographic and cultural eclipse as a moral imperative. Indeed, as I have noted previously, it is striking that racial nationalism has triumphed in Israel at the same time that the Jewish intellectual and political movements and the organized Jewish community have been the most active and effective force for a non-white America. Indeed, a poll in 2008 found that Avigdor Lieberman was the second most popular politician in Israel. Lieberman has advocated expulsion of Arabs from Israel and has declared himself a follower of Vladimir Jabotinsky, the leading pioneer of racial Zionism. The most popular politician in the poll was Benjamin Netanyahu � another admirer of Jabotinsky. Prime Minister Ehud Olmert and Foreign Minister Tzipi Livni are also Jabotinskyists. The racial Zionists are now carrying out yet another orgy of mass murder after a starvation-inducing blockade and the usual triggering assault designed to provoke Palestinian retaliation � which then becomes the cover for claims that Israel is merely defending itself against terrorism. This monstrosity was approved by overwhelming majorities of both Houses of Congress. The craven Bush administration did its part by abstaining from a UN resolution designed by the US Secretary of State as a result of a personal appeal by the Israeli Prime Minister. This is yet another accomplishment of the Israel Lobby, but one they would rather not have discussed in public. People might get the impression that the Lobby really does dictate US foreign policy in the Mideast. Obviously, such thoughts are only entertained by anti-Semites. But I digress. In managing the eclipse of white America, one strategy of the mainstream media is to simply ignore the issue. Christopher Donovan (�For the media, the less whites think about their coming minority status, the better�) has noted that the media, and in particular, the New York Times, are quite uninterested in doing stories that discuss what white people think about this state of affairs. It�s not surprising that the New York Times � the Jewish-owned flagship of anti-white, pro-multicultural media � ignores the issue. The issue is also missing from so-called conservative media even though one would think that conservatives would find the eclipse of white America to be an important issue. Certainly, their audiences would find it interesting. Now we have an article �The End of White America� written by Hua Hsu, an Assistant Professor of English at Vassar College. The article is a rather depressing display of what passes for intellectual discourse on the most important question confronting white people in America. Hsu begins by quoting a passage in F. Scott Fitzgerald�s The Great Gatsby in which a character, Tom Buchanan, states: �Have you read The Rise of the Colored Empires by this man Goddard?� � Well, it�s a fine book, and everybody ought to read it. The idea is if we don�t look out the white race will be�will be utterly submerged. It�s all scientific stuff; it�s been proved.� Buchanan�s comment is a thinly veiled reference to Lothrop Stoddard�s The Rising Tide of Color which Hsu describes as �rationalized hatred� presented in a scholarly, gentlemanly, and scientific tone. (This wording that will certainly help him when he comes up for tenure.) As Hsu notes, Stoddard had a doctorate from Harvard and was a member of many academic associations. His book was published by a major publisher. It was therefore �precisely the kind of book that a 1920s man of Buchanan�s profile � wealthy, Ivy League�educated, at once pretentious and intellectually insecure � might have been expected to bring up in casual conversation.� Let�s ponder that a bit. The simple reality is that in the year 2009 an Ivy League-educated person, "at once pretentious and intellectually insecure," would just as glibly assert the same sort of nonsense as Hsu. To wit: The coming white minority does not mean that the racial hierarchy of American culture will suddenly become inverted, as in 1995�s White Man�s Burden, an awful thought experiment of a film, starring John Travolta, that envisions an upside-down world in which whites are subjugated to their high-class black oppressors. There will be dislocations and resentments along the way, but the demographic shifts of the next 40 years are likely to reduce the power of racial hierarchies over everyone�s lives, producing a culture that�s more likely than any before to treat its inhabitants as individuals, rather than members of a caste or identity group. The fact is that no one can say for certain what multicultural America without a white majority will be like. There is no scientific or historical basis for claims like �the demographic shifts of the next 40 years are likely to reduce the power of racial hierarchies over everyone�s lives, producing a culture that�s more likely than any before to treat its inhabitants as individuals, rather than members of a caste or identity group.� Indeed, there is no evidence at all that we are proceeding to a color blind future. The election results continue to show that white people are coalescing in the Republican Party, while the Democrats are increasingly the party of a non-white soon-to-be majority. Is it so hard to believe that when this coalition achieves a majority that it will further compromise the interests of whites far beyond contemporary concerns such as immigration policy and affirmative action? Hsu anticipates a colorblind world, but affirmative action means that blacks and other minorities are certainly not treated as individuals. And it means that whites � especially white males � are losing out on opportunities they would have had without these policies and without the massive non-white immigration of the last few decades. Given the intractability of changing intelligence and other traits required for success in the contemporary economy, it is unlikely that 40 more years of affirmative action will attain the outcomes desired by the minority lobbies. Indeed, in Obama's America, blacks are rioting in Oakland over perceived racial injustices, and from 2002 �2007, black juvenile homicide victims increased 31%, while black juvenile homicide perpetrators increased 43%. Hence, the reasonable outlook is for a continuing need for affirmative action and for racial activism in these groups, even after whites become a minority. Whites will also lose out because of large-scale importation of relatively talented immigrants from East Asia. Indeed, as I noted over a decade ago, "The United States is well on the road to being dominated by an Asian technocratic elite and a Jewish business, professional, and media elite." Hsu shows that there already is considerable anxiety among whites about the future. An advertizing executive says, �I think white people feel like they�re under siege right now � like it�s not okay to be white right now, especially if you�re a white male. ... People are stressed out about it. �We used to be in control! We�re losing control�� Another says, "There�s a lot of fear and a lot of resentment." It's hard to see why these feelings won't increase in the future. A huge problem for white people is lack of intellectual and cultural confidence. Hsu quotes Christian (Stuff White People Like) Lander saying, "I get it: as a straight white male, I�m the worst thing on Earth." A professor comments that for his students "to be white is to be culturally broke. The classic thing white students say when you ask them to talk about who they are is, �I don�t have a culture.� They might be privileged, they might be loaded socioeconomically, but they feel bankrupt when it comes to culture � They feel disadvantaged, and they feel marginalized." This lack of cultural confidence is no accident. For nearly 100 years whites have been subjected to a culture of critique emanating from the most prestigious academic and media institutions. And, as Hsu points out, the most vibrant and influential aspect of American popular culture is hip-hop�a product of the African American urban culture. The only significant group of white people with any cultural confidence centers itself around country music, NASCAR, and the small town values of traditional white America. For this group of whites � and only this group � there is "a racial pride that dares not speak its name, and that defines itself through cultural cues instead�a suspicion of intellectual elites and city dwellers, a preference for folksiness and plainness of speech (whether real or feigned), and the association of a working-class white minority with 'the real America.'� This is what I term implicit whiteness � implicit because explicit assertions of white identity have been banned by the anti-white elites that dominate our politics and culture. It is a culture that, as Hsu notes, "cannot speak its name." But that implies that the submerged white identity of the white working class and the lack of cultural confidence exhibited by the rest of white America are imposed from outside. Although there may well be characteristics of whites that facilitate this process, this suppression of white identity and interests is certainly not the natural outcome of modernization or any other force internal to whites as a people. In my opinion, it is the result of the successful erection of a culture of critique in the West dominated by Jewish intellectual and political movements. The result is that educated, intellectually insecure white people these days are far more likely to believe in the utopian future described by Hsu than in hard and cautious thinking about what the future might have in store for them. It's worth dwelling a bit on the intellectual insecurity of the whites who mindlessly utter the mantras of multiculturalism that they have soaked up from the school system and from the media. Most people do not have much confidence in their intellectual ability and look to elite opinion to shape their beliefs. As I noted elsewhere, A critical component of the success of the culture of critique is that it achieved control of the most prestigious and influential institutions of the West, and it became a consensus among the elites, Jewish and non-Jewish alike. Once this happened, it is not surprising that this culture became widely accepted among people of very different levels of education and among people of different social classes. Most people are quite insecure about their intellectual ability. But they know that the professors at Harvard, and the editorial page of the New York Times and the Washington Post, and even conservative commentators like Rush Limbaugh and Sean Hannity are all on page when it comes to racial and ethnic issues. This is a formidable array, to the point that you almost have to be a crank to dissent from this consensus. I think one of the greatest triumphs of the left has been to get people to believe that people who assert white identity and interests or who make unflattering portrayals of organized Jewish movements are morally degenerate, stupid, and perhaps psychiatrically disturbed. Obviously, all of these adjectives designate low status. The reality is that the multicultural emperor has no clothes and, because of its support for racial Zionism and the racialism of ethnic minorities in America, it is massively hypocritical to boot. The New York Times, the academic left, and the faux conservatives that dominate elite discourse on race and ethnicity are intellectually bankrupt and can only remain in power by ruthlessly suppressing or ignoring the scientific findings. This is particularly a problem for college-educated whites. Like Fitzgerald's Tom Buchanan, such people have a strong need to feel that their ideas are respectable and part of the mainstream. But the respectable mainstream gives them absolutely nothing with which to validate themselves except perhaps the idea that the world will be a better place when people like them no longer have power. Hsu quotes the pathetic Christian Lander: "�Like, I�m aware of all the horrible crimes that my demographic has done in the world. ... And there�s a bunch of white people who are desperate � desperate � to say, �You know what? My skin�s white, but I�m not one of the white people who�s destroying the world.�� As a zombie leftist during the 1960s and 1970s, I know what that feeling of desperation is like � what it's like to be a self-hating white. We must get to the point where college-educated whites proudly and confidently say they are white and that they do not want to become a minority in America. This reminds me of the recent docudrama Milk, which depicts the life of gay activist Harvey Milk. Milk is sure be nominated for an Oscar as Best Picture because it lovingly illustrates a triumph of the cultural left. But is has an important message that should resonate with the millions of whites who have been deprived of their confidence and their culture: Be explicit. Just as Harvey Milk advocated being openly gay even in the face of dire consequences, whites need to tell their family and their friends that they have an identity as a white person and believe that whites have legitimate interests as white people. They must accept the consequences when they are harassed, fired from their jobs, or put in prison for such beliefs. They must run for political office as openly pro-white. Milk shows that homosexuals were fired from their jobs and arrested for congregating in public. Now it's the Southern Poverty Law Center and the rest of the leftist intellectual and political establishment that harasses and attempts to get people fired. But it's the same situation with the roles reversed. No revolution was ever accomplished without some martyrs. The revolution that restores the legitimacy of white identity and the legitimacy of white interests will be no exception. But it is a revolution that is absolutely necessary. The white majority is foolish indeed to entrust its future to a utopian hope that racial and ethnic identifications will disappear and that they won�t continue to influence public policy in ways that compromise the interests of whites. It does not take an overactive imagination to see that coalitions of minority groups could compromise the interests of formerly dominant whites. We already see numerous examples in which coalitions of minority groups attempt to influence public policy, including immigration policy, against the interests of the whites. Placing ourselves in a position of vulnerability would be extremely risky, given the deep sense of historical grievance fostered by many ethnic activists and organized ethnic lobbies. This is especially the case with Jews. Jewish organisations have been unanimous in condemning Western societies, Western traditions, and Christianity, for past crimes against Jews. Similar sentiments are typical of a great many African Americans and Latinos, and especially among the ethnic activists from these groups. The �God damn America� sermon by President Obama's pastor comes to mind as a recent notorious example. The precedent of the early decades of the Soviet Union should give pause to anyone who believes that surrendering ethnic hegemony does not carry risks. The Bolshevik revolution had a pronounced ethnic angle: To a very great extent, Jews and other non-Russians ruled over the Russian people, with disastrous consequences for the Russians and other ethnic groups that were not able to become part of the power structure. Jews formed a hostile elite within this power structure � as they will in the future white-minority America; Jews were �Stalin�s willing executioners.� Two passages from my review of Yuri Slezkine's The Jewish Century seem particularly appropriate here. The first passage reminds me of the many American Jews who adopt a veneer of support for leftist versions of social justice and racial tolerance while nevertheless managing to support racial Zionism and the mass murder, torture, and incarceration of the Palestinian people in one of the largest prison systems the world has ever seen. Such people may be very different when they become a hostile elite in a white-minority America. Many of the commentators on Jewish Bolsheviks noted the �transformation� of Jews [after the Bolshevik Revolution]. In the words of [a] Jewish commentator, G. A. Landau, �cruelty, sadism, and violence had seemed alien to a nation so far removed from physical activity.� And another Jewish commentator, Ia. A. Bromberg, noted that: the formerly oppressed lover of liberty had turned into a tyrant of �unheard-of-despotic arbitrariness��. The convinced and unconditional opponent of the death penalty not just for political crimes but for the most heinous offenses, who could not, as it were, watch a chicken being killed, has been transformed outwardly into a leather-clad person with a revolver and, in fact, lost all human likeness. ... After the Revolution, ... there was active suppression of any remnants of the older order and their descendants. ... The mass murder of peasants and nationalists was combined with the systematic exclusion of the previously existing non-Jewish middle class. The wife of a Leningrad University professor noted, �in all the institutions, only workers and Israelites are admitted; the life of the intelligentsia is very hard� (p. 243). Even at the end of the 1930s, prior to the Russification that accompanied World War II, �the Russian Federation�was still doing penance for its imperial past while also serving as an example of an ethnicity-free society� (p. 276). While all other nationalities, including Jews, were allowed and encouraged to keep their ethnic identities, the revolution remained an anti-majoritarian movement. The difference from the Soviet Union may well be that in white-minority America it will not be workers and Israelites who are favored, but non-whites and Israelites. Whites may dream that they are entering the post-racial utopia imagined by their erstwhile intellectual superiors. But it is quite possible that they are entering into a racial dystopia of unimaginable cruelty in which whites will be systematically excluded in favor of the new elites recruited from the soon-to-be majority. It's happened before. Kevin MacDonald is a professor of psychology at California State University�Long Beach. Permanent URL with hyperlinks: http://www.theoccidentalobserver.net/articles/MacDonald-Hsu.html ----------- Should Christians Support Israeli Terrorism in Gaza? A timely discussion between Rev. Ted Pike and Dr. David Duke, one especially important for the Christians in our audience http://www.davidduke.com/mp3/dukeradio090122DukeandPikeonGaza.mp3 In this vital discussion, Rev. Pike and Dr. Duke explore the Pro-Israel attitude of some Christian evangelical organizations, and why their position not only goes directly against Christian morality and decency, but actually is directly opposite of that expressed by Christian Scriptures. Today, Many Christians are instructed that Jews and today�s Israel has a special covenant� with God. In fact, the New Testament in the clearest of language states that the Jews �continued not in my covenant, and I considered them not, saith the Lord.� Here�s the quote that Christians aren�t supposed to notice.: 8:10 Not according to the covenant that I made with their fathers, in the day when I took them by the hand out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord. (Hebrews 8:10) They also don�t seem to notice that a 2000 year old Judaic war against Christianity that has been waged since time of Jesus Christ and still goes on today with the most powerful Jewish organizations attempting to destroy European and American traditions, that has even become a war on our Christmas traditions. Dr. Duke and Ted Pike also speak about how over a hundred thousand Christian Palestinians have suffered with their families from anti-Christian Israel! Christian support of Israel has resulted in the very birthplace of Jesus Christ, go from 90 percent Palestinian Christians to 35 percent today because of Israeli terror and occupation. They ask, �How could any Christian in good conscience support the anti-Christian state of Israel, bombing the homes, killing and maiming, torturing and oppressing fellow Christian men, women and children?� This is a vital show for every Christian reader and listener of DavidDuke.com. Next time, you hear someone say, �God tells us that we must support Israel� you will have the clear Christian answer that just the opposite is true! For documentation on this be sure to read some of the well-footnoted, sample chapters of Jewish Supremacism and My Awakening.

Dear Matt, I wanted to git push a trivial patch, and found that 1- your instructions are slightly wrong. You say git push shell.common-lisp.net/project/erlang-in-lisp/git but it's actually git push USER@shell.common-lisp.net:/project/erlang-in-lisp/git 2- the git directory (and all the rest) has no group write permission, so only you can modify things.

[erlang-in-lisp-devel] latest erlang-in-lisp
by Faré 15 Aug '08

15 Aug '08

After I go in the erlang-in-lisp/src/ directory, M-x slime-load-system erlang-in-lisp and (it.bese.fiveam:run!) I experience strange bugs: * multiple processes are running connected to the same fd used by SLIME, and SLIME gets confused the hell out of it. * one of the processes ends up at the ldb prompt because a GC invariant is lost (!), and at least one process isn't, which also confuses SLIME. * pstree -p shows 1 parent sbcl, 1 child sbcl, and four children {sbcl} whatever that means (threads?) * In case that's what happens, note that it is a very very bad idea to fork a process after you've started spawning threads, least you (and all the libraries you use -- good luck) take special measures with pthread_atfork(). * The 5am run wasn't very verbose (but had messages pasted in the mix possibly by children not heeding the redirection), and I couldn't find the dribble log (if any) so I don't know which test fails. Matt, can you advise? You may find help from people on irc #lisp, and/or me, etc. Otherwise, considering it's "pencil down" period, you should probably focus on fixing bugs and writing documentation.

[erlang-in-lisp-devel] watching processes
by Faré 15 Aug '08

15 Aug '08

Some ideas to add to a TODO file for e-i-l. Watching other processes is hard to do reliably in Unix. If the processes are linked by parent/child relationships, then the parent can easily watch if children die with SIGCHLD (and *must* do it to avoid zombies) - but this is not general enough mechanism for e-i-l. Another option is to share a pipe with the other process before you even fork, and add the watching of it in your epoll loop, so you can say the process is dead when you get an EPOLLHUP. This depends on all the considered processes following the proper convention of sending around the fd to the pipe, and so is not applicable to watching arbitrary other processes, but may work. It might be possible to open an fd on some file in /proc/$pid and receive an event when the process dies. Or not. These solutions require experimentation, but have the advantage that they are not subject to the same race conditions as having to register with a central server after you've forked.

[erlang-in-lisp-devel] Funs
by Robert Virding 08 Aug '08

08 Aug '08

Hi sorry I have been a bit lazy here. I have been reading through what Matt Bone has written in is his blog and would like to comment. As his entries are a bit old I thought this might be a better way to get info to him. Correct me I am wrong here. First about how funs are implemented in the BEAM today. The compiler, in the v3_kernel module, breaks out funs into separate "normal" functions with the free variables added as explicit variables. In the kernel erlang format all functions are flat with unique variables and have proper atom names. For the fun functions the name is built up from the function in which the fun occurs and an fun index, something like '-foo/3-anonymous-3-'. The fun itself is basically a tuple containing the module name, the fun function name, and the actual values of the free variables. There is also a unique tag to make sure that you can only call a fun in the same module as it was defined. This is needed as funs functions are called by name. Note that there is no code in the fun, calling a fun needs the right module to be loaded and it has to be exactly the same version of the module. This can be difficult running distributed erlang. It also mans that funs are not realy safe over code loading as you can have a fun which points to a too old version of a module which has been purged. Funs were not part of the original language/implementation and added after the basic code handling had been defined. In this respect they don't really fit in as well as they could. I hope this may help a little. I will get back soon on signals and messages and how they interact. One thought on using the front-end of the existing Erlang compiler. Core erlang, which is generated by the v3_core module, is very lisp like. Most of it will directly translate to basic lisp except for patterns, and the try and catch constructions. One hint there is to look at my LFE where I go the opposite way and compile to core elang. The basic LFE forms are actually very close to core erlang and LFE try is handled the same as ERlang try and generates the same core code. Another thought might be to use kernel erlang instead as it is simpler and the pattern matching has been compiled out. Robert

[erlang-in-lisp-devel] Fwd: Invitation to beta-test new Common Lisp webserver
by Faré 21 Jul '08

21 Jul '08

antiweb seems to be using a lot of the techniques we'd like for an erlang-in-lisp implementation: processes that communicate through messages, efficient event loop to manage a great number of connections, etc. [ François-René ÐVB Rideau | Reflection&Cybernethics | http://fare.tunes.org ] A tautology is a thing which is tautological. ---------- Forwarded message ---------- From: <doug(a)hcsw.org> Date: 2008/7/17 Subject: Invitation to beta-test new Common Lisp webserver To: fahree(a)gmail.com Hi Faré, We spoke earlier on IRC and apparently have similar ideas about server design so I thought you might be interested in having a look at a webserver I have been working on: http://hoytech.com/antiweb/ I'm appending the first section of the "Design of Antiweb" page of the manual. Best, Doug Antiweb is a webserver written in Common Lisp, C, and Perl by Doug Hoyte and Hoytech. Antiweb is not a "proof of concept" and is not "exploratory code". We intend the core design of Antiweb (as laid out in this design paper) to be stable for the next 10+ years of use. The two webservers that have had the largest influence on Antiweb4 are nginx and lighttpd. We took liberal advantage investigating these and other excellent servers while designing Antiweb4. Another more obscure server that has influenced Antiweb is fhttpd. Why another webserver? In our opinion, the biggest problem with the above servers is that they aren't written in lisp. Many servers that we studied have grafted on extension languages (ie, Perl for nginx and Lua for lighttpd). Antiweb is different. Instead of being a C program that uses some other language, Antiweb is a lisp program that uses C (and Perl). Like nginx, lighttpd, fhttpd, and Antiweb3, Antiweb4 is an asynchronous or event-based server, meaning that a single thread of control multiplexes multiple client connections. Antiweb is a collection of unix processes. Connections are transferred between processes with sendmsg(). When this happens, any data that was initially read from the socket is transferred along with the socket itself. The socket is always closed in the sending process. To multiplex connections inside a process, Antiweb uses a state machine data structure defined in src/libantiweb.h. Antiweb requires either the kqueue() or epoll() stateful level-triggered event APIs. * On a 32-bit linux/CMUCL system, 10000 inactive keepalive connections consume about 3M of user-space memory (in addition to two lisp images). * The number of inactive keepalive connections has negligible performance impact on new connections. There are three modes for sending files: medium, small, and large: 1. Medium: These files are mmap()ed (memory mapped) to avoid copying the file's data into user-space. The data is copied directly from the filesystem to the kernel's socket buffer. 2. Small: These files are read into a user-space buffer because a small read() is often cheaper than mmap()+munmap(). 3. Large: Antiweb uses a user-space buffer for large files. This is to avoid disk-thrashing when serving many large files to clients concurrently (idea from lighttpd) and to avoid running out of address space on 32 bit systems. Super-size it: Because Antiweb uses a 64-bit off_t type and lisp's unlimited precision integers on all systems, Antiweb can serve files of any size. It also supports download resuming for all three file send modes. Antiweb's data structures are designed for pipelining. Antiweb uses vectored I/O (also known as scatter-gather I/O) along with non-blocking I/O nearly everywhere. Antiweb's internal message passing protocol uses pipelining also. For example, an HTTP connection that pipelines two requests for small files followed by one request for a medium file is responded to with a single writev() system call consisting of the following: * The HTTP headers and file contents for the first two small files * The HTTP headers for the medium file * As much of the memory mapped medium file as it takes to fill the kernel's socket buffer. Subsequently, all the generated log messages are written to the hub process with another writev(). The hub will eventually append the log messages (as well as any others that queue up) onto the axslog log file. To see the connection statistics of a worker process, use the -stats command: # antiweb -stats /var/aw/example.conf ... Keepalive Time: 65 seconds Total Connections: 41 HTTP requests: 72 Avg reqs/conn: 1.8 File descriptor usage (estimate): 17/32767 Current Connections: 11 Keepalives: 7 Sending files to: 2 Proxy: Sources: 0 Sinks: 0 Idle: 0 Timers: 0 Hub: 1 Unix Connections: 1 Lingering: 0 Zombies: 0 ... Notice that in addition to the HTTP traffic, there is also a connection to the hub's unix socket that was opened on start-up, and one other open unix socket. That other unix socket is you. You created a supervisor connection while asking for stats info. -stats will also tell you how hosts are mapped to directories on a worker: # antiweb -stats /var/aw/example.conf ... Host -> HTML root mappings: localhost -> /var/www/testing example.com -> /var/www/example.com www.example.com -> /var/www/example.com ... Although usually we love it, sometimes pipelining is bad. Antiweb deliberately tears down persistent HTTP connections on certain responses: * 4XX and 5XX HTTP Errors - This is to prevent blind web vulnerability scanners like nikto from persisting or pipelining 95+ percent of their requests. * Directory Listings - To prevent pipelined recursive crawling. When finished with a connection, Antiweb will shutdown the write direction of the socket and linger as required by HTTP/1.1. Antiweb always gracefully degrades for HTTP/0.9 and HTTP/1.0 clients. Antiweb has first-class IPv6 support. If you really do want to pipeline 4XX and 5XX errors, you have two options: 1. Use Antiweb's rewrite module to change problematic requests into requests for existing files. 2. Use Antiweb's fast-files module. This is a memory cache that supports accelerated static content, pre-generation of HTTP headers, negative caching, and persisting/pipelining 404 errors. Antiweb was designed with security in mind from the beginning. Here are some of the security decisions made during the Antiweb design process: * Virtual hosts are privilege-separated without proxying. Once the hub has determined which worker should handle a connection, it transfers the socket to the worker process and has nothing further to do with the connection. Worker processes run under different UIDs from the hub (and each-other). Workers are optionally chroot()ed. * Workers have no access to log files: all log messages are sent to the hub over the unix socket. This means that a compromised worker process cannot steal previously created log messages or log messages created by other workers. * CGI processes can be restricted with resource limitations. * Even on lisps without unicode support, Antiweb4 guarantees all internal data and filenames are UTF-8 encoded. This includes verifying all code-points are in their shortest possible representation and that there are no otherwise invalid surrogates. * Antiweb processes never try to clean-up or recover in the event of an unexpected condition. A process cannot do that because it has failed. Some other process that hasn't failed will clean-up after it. Antiweb also includes an experimental new technology for constructing webpages called Anti Webpages. These are Perl-inspired programs that let you draw page layouts with significant whitespace, glue together HTML/CSS/Javascript, and more. Antiweb was created for admins, by admins. Please let us know any ways you think it could be better. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQFIfuKO3LTjmOMguVMRAvfUAJ4kg5aWoMfmHkrcWHvITs8Sqa9oEgCeMqPP lOxSU0c6lc3ZU1BOTH6L79w= =9+fV -----END PGP SIGNATURE-----

[erlang-in-lisp-devel] back to work
by Faré 12 Jul '08

12 Jul '08

I'm now just back from vacations, and will be more available for work on Erlang-in-Lisp. I am asked to submit a Mid-term review of Erlang-in-Lisp. Matt, can you produce a short document that describes what was done already, and what's you intend to focus on next? NB: This post was seen on Planet Lisp: http://www.foldr.org/~michaelw/log/programming/lisp/erlang-common-lisp Some other person seems to already tackle the part where a Lisp client talks to an Erlang server, but it looks like it's using an ad-hoc TCP/IP protocol rather than a native Erlang wire protocol. Distel looks more promising as a code base for future Lisp and Erlang integration.

[erlang-in-lisp-devel] deleted git branch
by Matt Bone 07 Jul '08

07 Jul '08

For the last several weeks I've been doing my work in the epmd branch. I merged all those changes with the master branch tonight and deleted it. If you were on the epmd branch you can: git checkout master ;;gets you back on master branch git pull http://common-lisp.net/project/erlang-in-lisp/git master ;;gets latest changes Or if you are on the master branch already, the previous pull (or make pull) will fetch the latest changes as usual. This is still pretty SVN-ish behavior, but hey, it works for now. --matt

[erlang-in-lisp-devel] Hi, I'm here to help
by Wesley Bitomski 11 Jun '08

I'm Wesley and I have experience writing code. Although my style may not be refined, I'm tenacious. I've read what's going on, so on a macro-level I understand what you're aiming to accomplish. Since I'm new to your project, I'm hesitant to start acting on my own. Is there anything specific that you want me to start working on? Test cases? Documentation? Beating up on a frustrating problem? Also: What implementation are each of you running? I have a machine that runs emacs slime with clisp. Does this matter, or should I be using something else? Thanks for having me, I found out about the project through Facebook, and was asked to join this group by Mr. Rideau to start participating. ~Wesley
