Technical people are too easy to exploit by malignant manipulators of people. All too often they don't even realize it after the fact.

Hi Tomaz, Have you checked Win32WideString in Pharo7/8 and its users? You can do aWindowsWideString := âa wide stringâ asWin32WideString. And then check the senders of Win32WideString, you will find you can declare ffi signatures like this removeEnvironmentVariable: nameString ^ self ffiCall: #( int SetEnvironmentVariableW ( Win32WideString nameString, 0 ) ) Isnât this working for you? If not, Iâd like to have more details on why it does not work, so we can figure out a solution :) Cheers, Guille > El 13 sept 2019, a las 15:22, TomaÅ¾ Turk <tomaz.turk(a)ef.uni-lj.si> escribiÃ³: > > OK, I'm proceeding with the library that I mentioned (http://disphelper.sourceforge.net/ <http://disphelper.sourceforge.net/>) and I got nice results.

It seems that there's nothing wrong with the primitive, but with Win32Variant creation in ExternalStructure class>>fromHandle:, specifically with basicNew and Win32Variant class as receiver. In what circumstances the debugger/inspector shows 'error printing' message (on the result of basicNew)? Sorry for newbie questions :-) Best wishes, Tomaz -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

These codes of conduct are being used around the net to force progressive political ideology into technical communities, the vague language is used to claim offense at any number of things like misgendering, or refusing to use any number of made up pronouns.

Re: [Pharo-users] Code of Conduct

by Richard O'Keefe

There was a point raised in the Ruby discussion (where my thoughts about Matz changed from "inventor of a language that filled a much-needed gap" to "really thoughtful so maybe I was wrong about Ruby") which I think is sufficient reason for a major revision to the Coraline Code. (For the record, I'm centre-left.) There is a process for punishing, but no process for restoration. Any morally acceptable code should be explicit that in the absence of a legal conviction, no person may be banned or locked out for more than some reasonable period, such as 2 years. If someone re-offends after such a period, impose another temporary ban or lockout. Given the way the concept of "harassment" has been misused, it no longer has any place in a code of conduct. Harassment these days is whatever the percipient judges it to be. There was a Pogo cartoon in which Pogo said "good morning" to a couple of other characters. Afterwards, one of them said to the other "Pogo is so mealy-mouthed that 'good morning' from him could be someone else's 'drop dead'." Then that was satire. Today it's reality. One of my daughter's friends was reported as harassing another woman. What did she do? Sat quietly in the car, looking straight ahead, neither saying anything nor moving. I know this because I was in the driver's seat at the time. The same woman accused my wife of harassing her. How? By sitting quietly in another room facing away from her. My wife's offence was that if this woman looked at her through an internal window, she could see her. I was sitting in the same room as the complainer at the time. If just sitting quietly minding your own business can be construed as harassment, NOBODY is safe.

A rudimentary disphelper library "approach" is working OK, I succeeded to create a connection to SQL Server through ADODB, too, which is rather cool, since I've been looking for this functionality for too long. I re-checked Pablo's pharo-com package and it is rather comprehensive - it successfully creates COM servers and more. However, when trying to invoke writing to COM server properties, as in: wordObj propertyNamed: 'Visible' put: true. the call fails with: Primitive failed: primitive #integerAt:size:signed: in ExternalAddress Problematic method uses a primitive <primitive: 'primitiveFFIIntegerAt' module:'SqueakFFIPrims'> which probably doesn't exist. Does anybody know about the purpose/intent and the history of this primitive in 'SqueakFFIPrims'? I think it would be a pitty that we leave Pablo's work unfinished. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

I think that even the "adoption" of such "Covenant CoC" introduces political ideology (and hence agenda) into this community that has been free from political debate (and so I expect it to be). > https://linustechtips.com/main/topic/974038-why-the-linux-coc-is-bad/ Oh my. > It's sad to see that Pharo has jumped onto this PC bandwagon, it does not bode well for the community. I believe this is more an undesired side effect of choosing a CoC from a template without caring about the details than the intention to have political correctness in the mailing list, because there's been flame wars and name calling here, but I don't recall anybody raising political ideology as an argument, or with the exception of a few cases, used political imagery or references in the ML, presentations, etc.. On a personal level I don't like this covenant in particular, and as was mentioned before it is not even a covenant since most of us just realized it existed and never before agreed to it. As a side note I believe mailing lists (or online communities in general) must not be safe spaces, and should only take action against concrete threats or completely off-topic comments/posts.
