In addition to showing how to launch Pharo, I'm also suggesting: - Putting 32 bit first (it's currently safer for a newcomer) - Moving new platforms to the top and older platforms lower in order - Removing reference to Ubuntu 12.04 since it is no longer supported. If you've got any other suggestions, please let me know and I'll be happy to incorporate them.

by Tim Mackinnon

Actually - I think its as simple as just adding && ./pharo-ui Pharo.image To the shown command? (Although maybe showing it as 2 steps makes it clearer that you donât need to download each time) Tim > On 12 Jun 2017, at 19:48, Tim Mackinnon <tim(a)testit.works> wrote: > > Hi - I was wondering why the command line section on the http://pharo.org/web/download <http://pharo.org/web/download> page, doesnât show you how to then launch the app you have just downloaded? > > Iâm not sure if there is a way to do it all on one line (I tried && ./pharo-ui Pharo.image - but this doesnât work).

Why don't the Zero Conf examples show how to launch Pharo?

by Tim Mackinnon

Hi - I was wondering why the command line section on the http://pharo.org/web/download <http://pharo.org/web/download> page, doesnât show you how to then launch the app you have just downloaded? Iâm not sure if there is a way to do it all on one line (I tried && ./pharo-ui Pharo.image - but this doesnât work). However I think the website example should at least have: # then run it ./pharo-ui Pharo.image Otherwise we make it harder for people to figure out what to do with the program weâve pointed them to?

We need to clean the image in Pharo7â¦ e.g. remove all the old versions of things that we have now a new version of. For Pharo 6: you can unload some things (e.g. Help packages, maybe tests) to shrink (see ImageCleaner). For Pharo7 with the bootstrap we are already better: Image size is 30MB instead of 36, and I think people will use the bootstrap to build images specialised much more (e.g without UI, but remote tools). > CPU + ~0.005s per real second passed (think of Amazon AWS why that could matter) > (In ~1400s wall clock 57.8s vs. 50.86s cpu time was used) > That is not goodâ¦ I think there where some changes regarding the main rendering loop. It might be interesting to track them down (since Phaor3 that is a lot of potential changes, though). Or better, think about a better headless way of running servers (no UI, use Remote tools instead). Marcus

Pharo crushes

by Moussa Saker

hello everyoneÂ I am working on project and we are using Roassal for visualization, the problem is that every time i execute my code Pharo crashes ( using the latest image 6.0 on Windows 10 64 bits machine), knowing that the same code runs fine on my collaborators Mac OS machines. Is there any solution that you could offer in such case ? Â Moussa Saker LISCO Laboratory Badji Mokhtar-Annaba University, P.O. Box 12, Annaba 23000, Algeria

Fwd: [Off topic] BHP Recruitment & Resource Industry Hackathon "Digital Tribes"

by Ben Coman

The global resources sector faces $1 trillion of impact in the next 10 years from new technologies. On the grapevine I hear that over the next few years BHP are recruiting 2000 people for their Digital Technology Revolution using IoT in the mining/energy/resources industry. "We are doubling our permanent workforce across the globe and have roles based in Australia, Chile (Santiago), Singapore and The United States (Houston)" http://careers.bhpbilliton.com/cw/en/job/789065/technology-revolution Forbe's rate BHP the world's 168th largest company and BHP seem to want to throw some serious money at innovation. As part of this BHP is sponsoring an online hackathon "Digital Tribes" https://www.unearthed.solutions/digital-tribes-perth/ based out of Perth - my home town. Applications are open to anyone around the world and will focus on IoT challenges. Whether you are a student, working full time or joining from anywhere around the world, if you are a "digital native" with hardware and software skills, then this one is for you. Challenge 1: Can you enable operational awareness on civil equipment to achieve compliance to our mine plans? Challenge 2: Can you design a prototype which operates in an ad hoc network suited for distributed safety devices? So the task is probably going to be something to do with location awareness of personelle around haul packs (look for the people in the photos) https://en.wikipedia.org/wiki/Haul_truck It would be really cool to get some Pharo into the mix of solutions. Regardless of individual team success or even want a job with BHP, Pharo could gain a lot from simple exposure to some of BHP's key innovation decision makers. This would ideally suit those with Pharo+RaspberryPi+hardware experience (I'm looking at you, robotics guys!) but also (I'm guessing) skills in data science and GPS-like triangulation algorithms. The first thing to do is to apply as an individual... Registrations: 12 June - 18 June Event dates: 30 June - 14 July BHP will then form the teams to get a broad range of skills in each team. For remote participants they aim to form teams in the same location or time zones. So I get the feeling that when they mention "digital native" they are looking for youth, maybe students or new graduates (sub-30yrs?) and are looking for the dynamics of how participants work together. So I think the focus is against existing teams and more on individuals. There is no harm in anyone registering (we can swarm them with "Pharo" just to make them curious), but particularly encourage your high quality students to apply, and even select a few local non-Pharoers with expertise you might lack. I'll hopefully have some more information about the challenges tomorrow. ---------- Forwarded message ---------- Hi Ben, If you would like to share Digital Tribes information with your network, you can use the below details. There is no cost to participate. Participants who register their interest will go through an application and selection process. If successful, every participant receives a Raspberry Pi Zero W, gets assigned a team and $50 to work on their prototypes. Teams have 2 weeks to work at their own pace and the prize is paid engagement with BHP. The competition seeks people with skills in data science, software development and hardware engineering. More information can be found here: http://unearthed.link/digitaltribesperth Teams submit their prototype designs and video pitches online. There is also a free Info Session at CORE next Monday <http://unearthed.link/UEDT17_IS> for people to find out more. [I will be attending this session and hopefully can provide additional info after this (if there is of interest) -ben] cheers -ben P.S. I copied in [pharo-dev] to ensure coverage, but please reply just to [pharo-users]. P.P.S. Upcoming weekend resource sector hackthons...

Re: [Pharo-dev] Parallel Port

by Facundo Vozzi

Hi Ben, I found IOST http://www.smalltalking.net/Goodies/Squeak/ to use io.dll, I think that it's fine for me. I'll try it on Pharo. I want to do this on a computer (and not with arduino for example) because my idea is to do a complete software to manage the brewing process on my little brewery and sense the temperature is just de beginning. Thanks for your answer.
