I'm concerned about the vague accusations without evidence. They also don't seem relevant to the discussion about how one's name got on various mailing lists.

If you have a provable accusation against them -- that they were acting **independently of the account administrator** to alter lists, then that would be significant. As Rob has stated, MailChimp did not do something by itself. The list was aggregated from previous lists and events in which people participated.

That's difficult. For instance, I don't know any non-commercial, open-source ISPs or domain registrars. Or hosting services, though one could run one's own servers. Don't see how you'd get around the need for a domain registrar though...use bare IP addresses?

You may have heard things but that does not make things true. Be careful what you believe or assume -- question the rumors you hear. Also, things change. An opinion that might have been valid once may not be any longer. Google and Microsoft are companies. Linux is not a company, it is an open-source project. A *company* that *provides a Linux distro* might do marketing to you. If you buy RedHat Enterprise Linux, you will likely get on their mailing list. (If I bought RHEL, they had *better* tell me what's going on...) You can likely opt out of most of their communications. Google's *business* is making recommendations. They provide personalized advertising recommendation services. If you use their free services then you *opt in* to having them use your web searches to select ads for sites that use Google advertising services. If retailers use Google services to place ads, and you shop on those retailers' sites, then they may show you ads relating to your purchases. This is just how personalized online advertising works. Frankly, I'd rather see ads for something I'm interested in. Google has repeatedly fought requests by governments to divulge personal information. Once Upon a Time, Microsoft earned its reputation as the Evil Empire, mainly based on pressuring PC manufacturers to ship products with Windows installed, and encouraging an argumentative employee culture. However, Microsoft has changed. If you want to point at a company as being the Evil Empire these days, you'd be more accurate pointing at Apple (cancelling licenses for Mac clones, suicides at Foxconn, restrictions on getting apps on iTunes, removing fitness tracker products from their stores because they might compete with the Apple Watch, etc. -- do a search for "apple anti competitive practices"). Microsoft now has significant open-source programs. They are also in the forefront among tech companies in reforming their employee culture. They *cancelled stack ranking*. I don't know if I can convey just how important and significant that is. Most other tech companies still do it in spite of research showing how it hurts performance and employee morale. Their new CEO, Satya Nadella, is an actual nice person. So, times change. -- Pat ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

This is a misunderstanding of the economics of online businesses. I'm worried that the statements of approval of this claim may skew future choices, and cause more work and hassle and expense. The companies that make money by showing advertising are *content providers* such as newspapers, TV networks, Q sites,... They have *no other source of revenue*. Hosting sites like GitHub make their money from *paid accounts*. They do not need advertising revenue. Just because the "public" face of GitHub is their free accounts does not mean that is the bulk of their activity. It is very common, and popular, for cloud sites to have a free tier. Even production hosting sites do this. It is good marketing and helps train folks to use their tools, so that when the time comes to recommend a hosting site or platform for a commercial project, they will naturally gravitate to the site they're already using and like. The idea that GitHub, or Heroku, or OpenShift, or Gitorious, or Bitbucket, or Pythonanywhere, or ShinyApps, or... would at some point go "Hah! You're trapped!" and start demanding payment for free accounts, inserting compulsory advertising, or otherwise attacking their clients is so odd that I have never before heard it expressed as a serious concern in any open-source organization. Given that GitHub is Linus Torvald's project, there may be poison pills in their charter to prevent this even in a hostile takeover. Imagine the reaction if one of these companies did what is being suggested. Their clients would vanish. It's not hard to move from site to site, especially if one is using a DVCS like git. The folks running these companies are not stupid, and most of the companies are associated with open source in some way. -- Pat ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

Re: [OSGeo-Discuss] Code of Conduct in Real Case
The conversation has gone on to the question of diversity in STEM fields, but if I can return to the original presentation for a moment... Perhaps we could look at it from a different perspective, namely, that of marketing and branding. Is this an effective advertisement? Does it accomplish the intended purpose? (Full disclosure: I'm not a professional, though I have worked for an advertising placement company. I am, however, very much a fan of good advertising and follow industry news.) Let's say we don't know what the purpose is. What can we extract from the presentation itself? The majority of the presentation is selling other reasons to attend FOSS4G 2015 besides the content of the conference itself. A significant portion advertises travel to Seoul, and includes traditional travel themes -- culture, entertainment, food, sights. Another has the feeling of a business development promotion. Another portion emphasizes interaction with other attendees, and especially fun interaction. What can we infer about the intended audience? With the exception of the three elements discussed in this thread, the presentation appears neutral. The Dali image, Girls' Generation, and multiple images of alcoholic beverages are elements that would appear intended to appeal to a specific demographic, unmarried men below middle-age. (Girls Generation is a group assembled by SM Entertainment, whose founder says the group is intended to appeal to men aged 30-40. However, they now have a significant female fan base in Japan.) Next, how effective is it? The presentation does not appear intended to stand on its own. I'm assuming that these slides were used with a verbal presentation? For instance, as others have noted, the meaning of the Dali image sequence is obscure -- it does not work without explanation. To make it work without a verbal pitch, ask, for each section, does the lead-in slide adequately establish what is being promoted in that section? And for each slide, ask, does this need a better caption? Given that this is promoting attendance based on things that are not part of the conference itself, it would be good to make that explicit right in the first slide. If it's intended to also promote the conference program, that might work better as a separate presentation, rather than trying to glue it onto this one. If the three elements in question would be off-putting to some potential attendees, it would be easy to replace at least the Dali image and the beer images. Note in a professional advertising campaign, the question would not be, can we get away with this? but rather, is it possible that this will turn away potential customers in our intended demographic, or could this in any way diminish our brand or cause a negative reaction? So *if* the question of offense comes up at all, then that would trigger fixing that part of the advertisement. I gather the point of the Dali sequence is to say that something can appear as one thing from afar, and otherwise close up. Perhaps use a photo mosaic image instead? (These are images constructed of many small images.) The beer images are jarring not so much because they feature alcohol, but because there are so many of them -- they are out of proportion to any other type of image. I'd recommend dropping slides 37-41 and keeping only 42 (which is a better image than 41). Similarly, for the food images (the second longest sequence), instead of multiple slides, tile them into one slide. The Girls Generation picture is more problematic, because they are a legitimate and popular group. Two things were jarring to me. First, that was the *only* culture image. There are other aspects to Seoul culture besides K-pop. A montage of several images showing a range of cultural aspects would de-emphasize the sex aspect. Second, with the exception of the Dali image, the appearance of a sexy image was unexpected. Note that part of the problem is that not many people outside of Asia will recognize Girls Generation -- they will just see young women in provocative dress and poses. (For contrast, ~everyone on the planet would recognize Psy.)

I hesitate to step into the sexism in tech debate, but... There may be some recent events that folks aren't aware of, that may be relevant -- some specifically have to do with conferences. This list is not R-rated, so rather than directly describe the relevant events, I'll just give you search queries that will bring them up: PyCon donglegate TechCrunch sexism Pax Dickenson brogrammer GamerGate Those are only tips of the iceberg -- they are specific symptoms of a more general attitude. I've listed them in order of seriousness. I expect that these will get the that's just PC objection, but are threats of rape and murder really just for fun? And if the objection is that women just just force their way into tech, I have two words for you: hiring manager. And no, not all of us have the resources to start our own companies. Venture funding is rarely offered to women. When I worked as a software engineer for Digital Equipment Corporation (DEC) in the 90s, the group I was in was half women. No, not secretaries and support staff -- engineers. But there was a difference in attitude, which one can see in the fact that although DEC ceased to exist in 1998 (sold to Compaq), we *still have reunions* and active social networks. The switch to deliberately provoking competition and infighting between employees, via stack ranking and similar management fads, is exacerbating the rise of sexism in tech -- there is now an aspect of us against them. Because employment is a zero-sum game, (re)entry of women in tech would mean fewer positions and less money for men. (Competing against other men doesn't trigger the same level of response since men are already in the pool -- it's the thought of the pool *doubling* that is causing this fear.) Since this style of management (stemming from Jack Welch) is taught in b-schools, it will take some time to turn the ship around. But there are some signs of light: Microsoft recently cancelled stack ranking, and is making a significant effort to reestablish teamwork and cooperation. That took being publicly shamed (see the article in Vanity Fair, titled ~ How Stack Ranking Killed Innovation at Microsoft) and a new CEO (Satya Nadella, replacing Steve Ballmer).

Re: [OSGeo-Discuss] Anyone openly georeferencing maps and pictures in time?
Tim -- This is a project idea which seems obvious to me, and one which would so obviously benefit from OSGeo involvement, that I feel someone on this list will know very quickly if anyone is working on it in an open data way. It comes from thinking about the warping which needs to be done to get from an aerial photograph to a map, and extending the thought to what can be done with a very oblique image - such as I might take standing on the ground. Any photo, not just an aerial one, can be considered as a map just waiting to be tagged with scale, projection, geolocation and date. The photo doesn't have to be great quality - perfection is not needed. In fact, if we allow some artistic licence, we could apply the same process to scans of historic prints and paintings. And if we had a library of such geotagged images, researchers would be able to specify an area and a time range, and search for images whose area of coverage overlapped it taken during the given period. It would be of antiquarian interest - there's an organisation I belong to called the London Topographical Society http://www.topsoc.org/front/index which has access to a mind-boggling number of maps, old photos and prints of London - but also to academics in Geography and Town Planning departments. It would also be of commercial interest to developers looking at the planning context for new developments. And I think I've read somewhere of commercial companies - Google, Facebook? - collecting various picture of the same location, e.g. a holiday destination, and using the combined data to produce images with unwanted obstructions eliminated. It has to be possible, so is anyone working on developing an open source library of images so tagged? Brief background on me; I'm a maths graduate, now approaching retirement, and with interests not only in history, but also urban development, so a project along these lines is something I'd love to get involved with. Although I might dream to doing some coding, that's just not realistic when my skills are more in MS Office applications and VBA. I've also been looking at 'R' and QGIS, and I could get to the point of doing the tagging, except for date stamping, but if there was anyone else further up the learning curves for these, it would be good to link up. I also have a lot of possible contacts with people who might be interested in such a project as users, which would also make a difference. It seems like such a nice project, so hoping someone can help This is a popular area, since it relates to side-scan sonar, side-looking aerial radar, and cameras suspended from drones, which, even if they're intended to be pointing down, rarely are. (It also seems to be somewhat a solved problem, just not open-source -- as you may guess, this has military use.) It also comes up in autonomous vehicles, since one wants to infer (for instance) distance of objects from imagery. For both this and georeferencing, sequences of (partly) overlapping images -- video -- are very useful. In fact, this subject is under current discussion over on the Humanitarian OpenStreetMap Team mailing list, with the revival of OpenAerialMap. I'd recommend joining up with the folks over there. I'm CCing some folks (Stephen Mather, Kate Chapman, Michael Patrick) who are involved with OpenAerialMap and / or OpenStreetMap and georeferencing in general.

The nature of Windows and Visual Studio tends to be what gets in the way of a more package management style system or build environment that's easy to replicate. I see no reason there can't be a shortcut in osgeo4w to setup source tree/libs for devs. ... Unlike OSGeoLive we can't supply VMs as that takes paid licenses for the software in question. I am no expert on Windows build tools but... If the goal is a *build script* to allow just pulling a new version from a repository and building dlls or exes, then it is possible to script builds using the compilers supplied with Visual Studio. Visual Studio supplies a shell with the appropriate environment variables and such set up. I've used cmake scripts that referenced Visual Studio (and had to hack cmake scripts that used obsolete VS build commands and obsolete VS versions). One does not need the full Visual Studio just for the compilers and build tools -- those are available with some of the free Visual Studio Express packages. http://www.microsoft.com/visualstudio/eng/products/visual-studio-express-products There are other compilers and build toolchains available for Windows -- e.g. MinGW -- but it seems (again, I'm not a Windows build expert...) one must use the same compiler / linker throughout, so it would likely be appropriate to pick one, and likely whichever is currently being used to build OSGEO4W executables. On the other hand, if the goal is a *development environment* that allows people to work on the code, and debug and test, then one might want an IDE. (I have not yet tried out Visual Studio Express as an IDE. I use both Eclipse and Netbeans on Windows, but have not tried building native Windows executables or libraries with them. I use them mainly for Java and Python). Does anyone have experience using Eclipse, Netbeans, or another FOSS IDE to build native Windows binaries? Do you use the Visual Studio (Express) compilers for that, or MinGW, or...? The issue with providing a VM image with a preconfigured development environment doesn't seem to hinge on whether the full, licensed, non-free Visual Studio could be included, but rather the fact that one would need a license for the guest Windows OS itself. If the developer or builder is running directly on Windows, then it's somewhat moot, so I'm guessing the VM suggestion is more for cross-compiling, or ease of installation...? -- Pat ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
