Smalltalk Software House Ideas/Infrastructure
by Keith 21 Oct '18

21 Oct '18

Hi Friends, I have lots of ideas that would move towards a platform which would make squeak et al. a killer platform in the software house arena, and a little spare time. In a commercial setting I myself have been very impressed with ST/X, particularly the ability to code methods in C, so I am always in favour of enabling all forks/variants to make the best use of all the hard work that has been put into developing package. I am not a one-fork guy. In the spirit of improving squeak for use in a commercial environment, I suggest we adopt the dormant se-tools mailing list for more detailed discussions. I also expect to be setting up a hierarchical wiki as a basis for collaboration. In the meantime check this out, this is a roller coaster we will want to be on https://www.youtube.com/watch?v=TRFd_b-2yXQ&feature=youtu.be warmest regards Keith

[grow] Process for developing and building images on all forks
by keith 15 Mar '10

15 Mar '10

Hi All, The news is that Magma now loads into Cuis, collecting a couple of missing things it needs on the way. It only takes 20 seconds to load everything. I admit that I haven't tested if it actually works yet, but I am happy it loads. "grow" is a new process for loading things into all your favourite images, you can see grow in action with the screeencast (link available here): Grow also loads the same magma distribution into trunk, squeak4.0, and pharo. Again, no guarantees that it actually works yet. http://smalltalkers.pbworks.com/Innovating-ALL-Smalltalks regards Keith ==== The series.st file I am using to load magma(testing) is as follows: InstallSeries addSource: 'library/base-dev'. InstallSeries addSource: 'base-dev'. Install load: 'library/magma/magma-server.st'. InstallSeries addTheTests

Obama -- The Judas Goat
by Ron Teitelbaum 25 Jan '09

25 Jan '09

Obama -- The Judas Goat 1/25/2009 By David Duke Judas Goat\ A goat that leads other goats or sheep to slaughter. Also, one who entices into danger and betrays others. The name is an allusion to Judas Iscariot, who betrayed Jesus for 30 pieces of slaughter. (From Merriam Webster�s Dictionary) Barack Hussein Obama is a Judas Goat. Extremist Jews guided Barack Hussein Obama�s career from day one, even all the way back to Harvard Law School. Radical Zionist hitman, David Axelrod previously orchestrated the Jewish-financed and organized defeat of perceived anti-Zionist Sen. Charles Percy. He is the man who ran Obama�s campaign for President and who is his chief handler. Obama�s campaign was overwhelmingly financed by the most powerful Zionist bankers in the world. His campaign�s largest contribution source was the Zionist international banking firm of Goldman Sachs. (FEC campaign records). In both Obama�s Senate and Presidential campaign he prostrated himself before AIPAC (American Israel Public Affairs Committee) promising even more money and blood for Israel�s terrorism than even the supine John McCain, and even more money and blood than the previous Shabbez Goy in the White House, George Bush. Before the Israeli terrorism and mass murder in Gaza, he went to Israel and said that he supported Israel�s planned murderous terrorism against the men, women and children of Gaza. His first act as President-elect was to appoint a rabid Zionist, Israeli dual citizen who served in the Israeli Army as his Chief of Staff, Rahm Emmanuel. As thousands of women and children in Gaza were killed or maimed, Obama remained silent. Within a few days as President Obama supported indiscriminate American missile strikes in villages of our ally Pakistan, a clear continuation of Bush�s policies. He completely supports the theft of trillions of American taxpayer dollars to the Zionist international bankers. Eighty percent of American Jews voted for Obama, and all the main leaders of the Jewish Supremacist state of Israel have proclaimed Obama as the perfect man for U.S. President. What better for the Zionists to have their own servant perceived as a clean break from the Jewish extremist-controlled Bush administration? What better than for the Zionists than to have their Shabbez Goy be treated by the world�s press and even by much of the anti-Zionist community as a man of �real change?� What better for the Zionists than for the world to think that Obama will be a change from the Zionist-controlled policies when he willing to do anything that Israel demands? What better for the Zionist murderers to have their craven puppet be looked at by the whole world as a man of honor and integrity and fairness. In the slaughterhouse, the Judas Goat is often painted with bright colors, adorned with strong, sweet scents to lure the sheep to their pens and to their death. Obama, the Judas Goat of our time, is looked upon by millions of Zionist-propagandized sheep as the man who will lead them to salvation. Instead, he leads America, Palestine and the world to the bloody altar of Jewish Supremacism. Any supposed anti-Zionist who praises Barack Obama is actually aiding this Judas Goat to lead us all to slaughter. Every person who truly opposes Jewish extremism must speak out and expose the Judas Goat named Barack Obama! -- Dr. David Duke Former Member of the House of Representatives State of Louisiana United States of America It is up to you the people of the United States who can still think freely, and up to all of the people of the world who are able to see through the deceptions of the Zionist-influenced Global media -- to get this simple, powerful message to everyone on earth. Email this message to your friends, post it on forums and websites and put links to it on every website, facebook or other media in the world. Go and seek out media and Internet sites not controlled by Zionist power. Make youtube videos of this message, (use the short audio and find good illustrative pictures) and post it untill your fingers are worn and tired, print it and mail it to newspapers or any media outlet that has still not fallen under the propaganda of the Zionists. Let the world know the truth. Person by person, in the USA, Canada, UK, France, Germany, Italy, japan, Russia, China, Africa, Palestine, South America and across the whole world this Judas Goat must be exposed for what he is, so that when begins to do his evil for Israel, the whole world will know exactly what is going on and resist! Source : http://www.davidduke.com/general/obama-the-judas-goat_7317.html ------------------------ Why is the President of Israel, the terrorist who just oversaw the Zionist mass murder and maiming of thousands of Palestinians so happy that Obama is President of the USA? by David Duke Read the excerpt from the Israeli News about how President Perez and Israel think that Obama�s becoming U.S. President is great day for Israel. "Israel�s President Shimon Peres ecstatic over the election of Obama" Ronen Medzini Israel News Jan. 21 �Today is a great day not only for the United States of America, but for the entire world,� President Shimon Peres wrote in a letter addressed to Barack Obama on the day of his inauguration as president of the United States. �Obama was elected by the United States, but as a matter of fact, he was chosen by the whole of humankind,� Why is Peres so ecstatic? Why shouldn�t he be, he knows that Obama is completely in the grip of the extremist Jewish Zionists in America, and he knows that the greater Obama�s popularity and idol worship, the more Obama can do for the International Zionist Cause. Any thinking and caring human being who realizes that the Zionist-controlled American foreign policy has been a disaster for the robbed and murdered people of Palestine, Lebanon, Iraq and a catastrophe for the 50,000 American wounded in Iraq and Afghanistan, as well as an economic catastrophe for the hardworking Americans who pay trillions to finance these wars for Israel -- must wake up the fact that supporting Obama and increasing his popularity will only aid Zionist terrorism, war, and their murder and oppression of the Palestinians. It will also hasten the economic suffering of billions of people around the world as his popularity enables him to more easily aid the Zionist International Bankers steal the wealth of the United States, Europe and the world. Obama is totally in the bloodstained and green ink- stained hands of the Zionists. The hard truth is that the more good will and support Obama has also gives more power to support the Zionist agenda! Mark my words. The Obama Presidency will be disaster for America and for the world. Obama was put into office by the Zionists. His top two cohorts for years have been the radical Jews David Axelrod and Rahm Emmanuel. Both have long records of radical Zionism and have been attack dogs against anyone perceived as having the slightest opposition to Israel. One such victim was Sen. Charles Percy, who both men worked to defeat and destroy because he dared to only be 99 percent rather than 100 percent pro-Israel. Rahm Emmanuel, a dual citizen of Israel who went to fight for Israel, he has a long pedigree of Jewish extremism. His father served in the Irgun Terrorist Gang and he himself is named after an Irgun terrorist. Zionist leaders in Chicago actually call Obama �the first Jewish President� and boast that Jews were key players in Obama�s every step up the ladder to President. from the very earliest days, extremist Jews were the largest contributors to his campaign. In the beginning of his Presidential bid, three Hollywood Jews that constantly make movies about Jewish suffering, but never about the Zionist terrorism and theft against the Palestinian people, Steven Spielberg, David Geffen, and Jeffrey Katzenberg raised 1.2 million for Obama in a single Hollywood party. By the time Obama�s campaign was in full swing, he had huge support from the criminal Zionist International Banking firms such as Goldman Sachs and Lehman brothers. Goldman Sachs was Obama�s biggest single contributor, and his vast war chest came not from American manufacturing firms like GM or even American oil companies, (not one was in his top twenty) it was overwhelmingly dominated by Zionist international bankers, the same ones whose thievery and fraud are giving the world this economic depression. For those looking for meaningful social and political change, do you really think it will come from this man who has already been bought heart, head and soul by the most powerful czars of the international financial establishment and the biggest globalists in the world? I know that many are desperate for change, so desperate that you want to believe anything. But in the face of these facts can�t you see that Obama will be even more dangerous to freedom and justice than even George Bush and his band of Neocons were. What better way to wipe out George Bush�s hated legacy and make the world believe that America has really changed than with the election of Obama. But, all the real Zionist power, Zionist media power, and Zionist financial power in America is still in place, even stronger than ever. Many Americans and others around the world who want to do good are now telling us how wonderful Obama will be as president. What a great change it will be from the old policies. This is because of the Zionist-Controlled media hype, promoting Obama. The fact is that these poor sods are ignorantly helping the radical Zionist agenda in Israel and around the world. Every day that you don�t help expose Obama for the Zionist servant that he actually is, his popularity will be a greater danger to peace and freedom. If the Zionist terrorist Shimon Perez is happy about the coronation of Obama, then why in the hell should you be? �David Duke Source : http://www.davidduke.com/general/7303_7303.html ------------------------------------- You or someone using your email adress is currently subscribed to the Lawrence Auster Newletter.

[Ann] Logging updated
by Keith Hodges 02 Dec '08

02 Dec '08

The logging front end to the 3 logging frameworks has been refactored and simplified. In the process it has become much more powerful. Highlights: Output Adapters, and AdapterSets: You can now "easily" set up as many output adapters as you like on any or all processes, each with different filters etc. Processes can share sets of adaptors. Lots of different output adapters are supported: Logging Frameworks: LogEngine, SimpleLog, Toothpick(not ready yet) Also direct support for: Transcript, nil, SLLogMorph, SLLogWatchDog (email), SLSyslogSender, SLLogFile New Feature: LogHistory. This adapter logs a given number of messages to memory. Then when you connect another adapter, it outputs the history to the new adapter. Thus giving you fast logging to memory, but still allowing you to catch up with a hard copy if you need it. It will only be a matter of time before we have an automatic, "when a big error occurs dump the in memory logs to a file" feature. If you are using Rio or Logging, please join the setools(a)lists.squeakfoundation.org list and put your feedback there or find me on irc #squeak. best regards Keith Installation: ========= Installer mantis ensureFix: '7219 Streams readability'. Installer squeaksource project: 'Logging'; install: 'Logging'. Installer squeaksource project: 'Logging'; install: 'SimpleLog'. Architecture: ================ LogCurrent the class is also a ProcessSpecific variable that returns an different instance of LogCurrent for each process. Each of these maintains a buffer for that process's log output. Users use 'self log' to obtain a LogCurrent buffer instance for the current process from 'LogCurrent value'. Since LogCurrent buffers are per-process they are threadsafe, and can maintain state between calls (self log properties). Each LogCurrent instance maintains a stream (on its buffer) and provides the users front end interface for convenient logging. Each LogCurrent instance maintains an adapter, when a log line is completed (#endEntry), the line is sent to the adapter, the adapter being the backend interface. The adapter may be any class that implements #logTime: stamp line: line level: level category: category sender: sender pid: pid e.g. Transcript. The adapter may also be a LogAdapterSet, in which case, the line is sent to each adapter contained in the set in turn. LogAdapterSets may be used to allow a number of processes to share the same set of adapters. LogAdapterSets may be arbitrarily nested, and may define a filterBlock. e.g. self filterBlock: [ :level :category | #(#error #debug #info) includes: level ]. AdapterSet may be subclassed if more specific filtering behaviour is required. Any changes to LogAdapterSets anywhere are protected by a single Semaphore, but use of adapters for output is protected instead by using a safer implementation of #do: to iterate over the set should an adapter be removed by a different thread. All processes that do not have a LogCurrent instance defined will copy the default LogCurrent instance, and will therefore share the same adapter/adapterset as the default. When you assign a bespoke LogCurrent instance to a specific process, it is up to you to set its adapter. It can include the global adapter/adapterset, nested within the new set you give it. Additional logging utilities and tools may be defined by subclassing LogCurrent. LogAdapterSet may be subclassed to provide more interesting filtering behaviour. And individual Adapters may also be configured or subclassed as desired. Adapters: =========== 1) LogHistory e.g. LogHistory size: 20. If the LogHistory adapter is present in a LogAdapterSet, then any new adapters added to that set have the recorded history sent to them immediately. Only one LogHistory adapter per set is allowed. 2) Blocks, LogAdapterSet may contain a block which returns a real adaper or nil. This enables adapters to be written to if enabled, or ignored if not available (see SLLogMorph below). 3) Transcript - the standard Transcript is used, and the line is output in one hit within the Transcripts own protection semaphore. 4) LogEngine e.g. LogEngine for: 'seaside'. This adapter is for the LogEngine backend. 5) SLLog This adapter is for the SimpleLog backend. 6) Toothpick This adapter is for the Toothpick backend. (Not yet supported) Direct to 'SimpleLog' Components 7) SLSyslogSender e,g, SLSyslogSender new addHost: 'log.somewhere.else'. or SLSyslogSender localhost. 8) SLLogWatchdog e.g. SLLogWatchdog default. Emails log entries over the given threshold 9) SLLogMorph e.g. [ SLLogMorph current ]. The block will be evaluated for every log entry. Therefore this construct will only write to LogMorph if it is open. 10) SLLogFile named: 'current.log'. Subclass and override #output*, or add #output* methods for additional file output formats. Or use (SLLogFile named: 'custom.log') output: [ :entry | entry stamp, '-', entry line ] Configuration: To change the global, or local LogCurrent instance LogCurrent default: MyLogBuffer new LogCurrent value: MyLogBuffer new To change the global adapters: LogCurrent default adapter: (LogAdapterSet with: Transcript). LogCurrent default adapter add: (LogHistory size: 20). To change the local adapter, logging to the current global adapters, and the local transcript, with a custom policy. newLog := MyOwnLogCurrent new. newLog adapter: (LogAdapterSet with: (LogCurrent default adapter) with: Transcript). LogCurrent value: newLog. Usable LogCurrent instance is returned from <code>self log<code> in whatever context it is used. The buffer is instanciated on a per process basis, therefore I am threadsafe already, and can reuse my buffers and maintain state as we progress through the code which we are logging. Unusually for a logging framework this allows us to perform timing tasks for our clients. If the code forks then a new buffer instance will handle the new forked process. For timing use: = self log timeTotal: #eventA. = self log timeDelta: #eventB. Convenient usage: 'annotated values' This uses the logging level defined by LogRouter-temp, and is considered a temporary log message for debugging purposes. For temporary log messages the specific level is rarely important. There is by default a global preference for disabling temporary log level messages. Of course your subclasses can override this behaviour. = self log x: 10 y: 20 z: 30. To select a specific log severity level (i.e. not the temporary one featured above). = self log info x: 10 y: 20 z: 30. To log the current method's input parameters. Rectangle-#corner: topLeftPoint extent: heightWidthPoint = self log debug this. would be the same as = self log corner: topLeftPoint extent: heightWidthPoint. To log the current methods variables: = self log debug it instance. = self log debug it temps. = self log debug it classVar. = self class log debug it instance. = self log debug vars all. Levels of detail: When logging it is useful to be able to specify easily the level of detail that we desire from the items we are given. Here we define 4 levels of detail. 1. Annotated values: the data points are simple values intended to be displayed on one line. the method selector is used to annotate the vaues for readability. = self log info r: 20 theta: 0.5. 2. Verbatim: Stream to the Log = (self log info << 'User Directory:' << aFilePath) write. 3. Detailed: human readable presentation: A detailed presentation of the objects internal state intended for human readability. The detail printed is based upon the object's explorer contents, as defined in #logDetailedOn: = self log info detailed: myDictionary. 4. Data Dumper: A machine readable serialized text format. The format printed is defined in #logDumperOn: For those perl coders out there who really like being able to recreate their data from logs! = self log info dumper: myTransaction.

About gnu plot
by Igor Stasenko 25 Sep '07

25 Sep '07

Balacz, Levente Need to let you know that i made a separate binding to gnuplot. I moved classes which was used to start gnuplot command into separate package, and also added some scripting abilities to make generating plots as easy as rendering html with seaside. Old classes, founded in Q2-Utilities-Gnuplot and Q2-Utilities-Gnuplot-Tests should be removed. -- Best regards, Igor Stasenko AKA sig.

Confirm an issue please.

Hi. I have an issue with viewing a case in remote magma setup. While in local magma setup all works just fine (in single image), but when i starting two images i got DNU's like: MessageNotUnderstood: UndefinedObject>>key it appears in Q2AssociationField>>renderViewControlOn: html component: fc because cache is nil. I investigated a problem and found, that field unable to read a value from case instance and returns nil values as default (so fieldcomponent case = nil). By placing a break in Q2AssociationField>>valueFromTarget: aTarget ifAbsent: aBlock and tracing it, i found that accessor is unable to send message to case instance because it returns false from #respondsTo: message. What is more strange is, that this happens following code to break: Q2SelectorAccessor>>valueFromTarget: aTarget ifAbsent: aBlock ^ (aTarget respondsTo: selector) ifTrue: [ aTarget perform: selector ] ifFalse: [ self break. aBlock value ] while aTarget is Q2Case instance and selector = #responsibleUserAndRole. And by entering in debugger and evaluating aTarget respondsTo: selector is returns true!!! I think something is wrong with maMutatingProxy when accessor object first time used to get value, its still is mutating proxy object and uses: #mutateAndSend: message. And something not working in this context. After mutating everything works ok, but what makes Q2Case instance respond false to first #respondsTo: message? I will continue debugging trying to figure out.. Maybe a 'selector' ivar in Q2SelectorAccessor is not reified correctly.. Btw, Levente i downloaded image from test2 (MagmaCounter.1.image), which you saying 'works fine'.. And guess what? It not working. So, please, confirm an issue or explain, what im doing wrong?? :) -- Best regards, Igor Stasenko AKA sig.
