If the goal is to get some files on or off the phone, there are also options to transfer files over the air rather than through a USB connection. I've tried Warpinator: https://flathub.org/en-GB/apps/org.x.Warpinator https://play.google.com/store/apps/details?id=slowscript.warpinator And Warp + Wormhole: GUI: https://flathub.org/en-GB/apps/app.drey.Warp CLI: https://magic-wormhole.readthedocs.io/en/latest/welcome.html Android: https://play.google.com/store/apps/details?id=eu.heili.wormhole Warpinator needs to be running on both ends and discover itself before you can send files. Wormhole lets you share and then launch the receiver, but the Android app only seems to be able to send one file at a time. If the files are small enough and you already have an account, the low effort way is probably to put them in Google Drive, Dropbox or OneDrive, and download them at the other end.

Yeah, the need to position yourself close enough to the speaker to hear and where you can also see the screen seems like it's painstakingly recreating downsides of the real world which shouldn't affect online presentations. I've used https://www.gather.town/ (not FOSS) for a work event before, which is a similar idea with a low-res 2D world.

I think this depends whether you can use their 'unlimited' personal backup ($60 per year). If there's some 'fair use' policy that doesn't let you store 16 TB, then their 'B2' cloud service is more like $1000 per year for this much. Even Amazon's 'Glacier deep archive' would be around $360 per year (with extra costs if you need to retrieve it). Some sources online reckon that good quality optical discs (but definitely not the cheap dye-based ones) are still a viable option, if you want to write the data once and then have it sit on a shelf for years. But Blu-Ray discs only go up to 50 or 100 GB per disc, which isn't practical for storing 16 TB.

That's no big surprise - I think memory is currently the limiting factor for most computers, and 4GB unfortunately doesn't stretch far these days. Browsers have essentially become operating systems, and complex web apps can use quite a lot of RAM (my about:performance currently shows one GMail tab using 140 MB). However, it looks like you can install additional memory in at least some of the Ideapad range, e.g.: https://uk.crucial.com/compatible-upgrade-for/lenovo/ideapad-510-(15-inch) Obviously double check the precise model if you're interested in doing that - it looks like there are quite a few flavours of Ideapad 510. But if that is a possibility, even a 16 GB stick is far cheaper than buying a new laptop with 8 GB of RAM (many of the cheapest laptops still have only 4 GB).

From what you describe, this wouldn't change often, so maybe an e-ink display would be a green option? As I understand it, e-ink only requires power to update, so it can be very efficient for something that's mostly constant. Second hand e-readers can be a cheap way to get a fairly large e-ink display. I was toying with this idea a few years ago, and found that old Kobo e-readers run Linux and are reasonably hackable - I think someone used one to display a weather forecast, for instance. That might be more involved than you want for a simple text sign, but I can dig out the links I found at the time if anyone is interested. If you can spend a bit more money and/or accept a smaller display, you can get e-ink displays to use with Raspberry Pis or microcontrollers, e.g. https://shop.pimoroni.com/?q=eink Thomas -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Sadly, that hasn't happened yet. We had an EdLUG meeting on Jitsi recently, and it worked pretty well for most people, with a couple of caveats: - We asked everyone to use Chromium/Chrome, because apparently one person on Firefox can cause issues for everyone. People are working on this, so hopefully it won't be necessary next time: https://github.com/jitsi/jitsi-meet/issues/4758 - A couple of people couldn't hear any sound until they allowed it to access a microphone.

Re: [Hampshire] Home user Linux Support opportunities in Southampton/Eastleigh area?
Hi Imran, It's not a business, but I recently started helping at the Southampton repair cafe, which runs monthly on the first Saturday of the month. Among other things, people bring in computers and electronic devices to be repaired. There's an explicit aim to help people keep using stuff rather than throwing it away and replacing it, which fits with one of the reasons people promote desktop Linux. Of course, most of the computers that come are Windows or Mac systems, though. The website unfortunately is down at the moment, and apparently the webmaster is on a long holiday, but here's the latest snapshot from the wayback machine: https://web.archive.org/web/20170611132036/http://transitionsouthampton.org/ If people at the cafe need more than ~30 minutes of help, I imagine you could offer your services for a later date. But obviously it would be disrespectful to treat the volunteer-driven event primarily as a chance to promote one's own services.

There isn't much detail there on what parts it uses, but the most likely problems in my experience are: 1. Graphics cards: If you're not interested in gaming, stick to Intel integrated graphics. Nvidia and AMD cards are more powerful, but the proprietary drivers introduce extra complications, and the open source ones may not be as robustly tested. Intel graphics play nicely with Linux. 2. Wifi - I'm less sure what to look for, but I think Intel chipsets are a good bet again. Again, the vast majority of chips will work, but some of them are more hassle than others. Any new laptop probably has UEFI secure boot - mainstream distros like Ubuntu/Fedora should be OK with that, but if you want something more niche, you may need to turn it off in the BIOS. A search with the model number turned up one issue reported with the touchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1593943 And a few threads about issues with the E15, but hopefully that's not the same as ES15. > I sent an enquiry to Acer, but have no reply.

Detect clickbait with machine learning Date: 6pm-7.30pm 3rd May 2017 Venue: University of Southampton, Nuffield Theatre Room 1083 (6/1083) - see https://maps.southampton.ac.uk/ Speaker: Oliver Laslett, Uni of Southampton Oliver has kindly agreed to run his tutorial which has already been accepted for PyData London, so this should be a really interesting session! Because this session is interactive, it will be a bit longer than our typical meetings: around 90 minutes. Nearer the date, a link to the tutorial materials will be available on the SPUG website and Google group. I won't spam other lists again for that, so keep an eye out if you're interested. http://southampton-python.github.io/ As usual, refreshments will be provided before the talk, and everyone is welcome to join us in the pub afterwards. Thanks, Thomas With this one weird trick you can build a text processing pipeline! We've all fallen for clickbait articles online. They pollute our news feeds and make it harder to filter out valuable information. In this workshop we'll stream news articles in real-time and detect clickbait using simple machine learning techniques. By the end of the workshop you'll have your very own python app for streaming real-time news and detecting click bait. In the workshop we'll cover: - Streaming data from a REST API - Preprocessing textual data - Training a simple machine learning classifier for clickbait - Putting everything together in a scikit-learn pipeline - Analysing our results (which news source is the most clickbaity?) -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Lenovo's Thinkpad line is still mostly pretty good with Linux, at least when I was looking last year. Those business-oriented systems seem to be developed separately to the consumer-grade ones which get in the news for the wrong reasons. The business lines are more expensive, but you do get a better built system. Is anyone interested in distilling the kind of info we're discussing into a nice 'how to buy a computer for Linux' website? Is there already such a site? I did one quick search and found posts like these: http://www.howtogeek.com/185286/how-to-buy-a-laptop-for-linux/ http://www.ebay.com/gds/Linux-Laptop-Buying-Guide-/1000177741943/g.html ...but no nice friendly overview site. Maybe this is something we could discuss/work on at a future PLUG meeting.

Re: [Hampshire] How to get a laptop with Linux?
System76 do a range of laptops with Ubuntu; they're US based, but ship internationally: https://system76.com/laptops Dell sell a few laptops with Ubuntu installed. The UK site usually seems to say they're unavailable, but maybe a phone call would have better results. The XPS 13 in particular is a pretty nice laptop. http://www.dell.com/learn/uk/en/ukbsdt1/campaigns/dell-linux-ubuntu-en?c=uk&l=en&s=bsd I think people mostly still buy Windows laptops and install Linux themselves. It's generally pretty smooth, but it's worth planning before you buy. Things I know to look out for: - Stick to Intel graphics unless you're keen to play games on it. Nvidia and AMD graphics do mostly work OK with their proprietary drivers, but it's a bit of extra hassle. - Try to find out what wifi chipset it uses and check what Linux support is like. Again, you can make just about anything work with some fiddling, but some are easier than others.

[Hampshire] Robotic Sailing talk, Monday 3rd October (Southampton Python group)
Hi all, The next Southampton Python User Group meeting will be on Monday, with a talk about robotic sailing: When: 6pm, Monday 3rd October Where: Room 1083, Nuffield Theatre (Building 6), University of Southampton. (Right by the university bus interchange, if you're coming on public transport) The speaker, Sophia Schillai, led a team from the University which earlier this month won the small boats class of the World Robotic Sailing Championship in Portugal. As usual, after the talk there will be a chance to give lightning talks - the suggested theme is robots, sensors, and code that interacts with the physical world. If you'd like to give a brief (maximum five minutes) talk, please let me know! Refreshments will be provided, and we'll go to a nearby pub afterwards for drinks and food. Best wishes, Thomas - Sophia led a team from the University of Southampton which recently won the World Robotic Sailing Competition (Micro Sailboat class). Come and hear about how we used Python and Linux to make a boat sail itself, including: - Why is it so hard to make a robot sail? - What happened to us at the World Robotic Sailing Championship (besides winning it)? - Who are ROS and Brian? - What tools did we combine to make the Black Python sail? -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

If it's a 32-bit program, it will need a complete set of 32-bit libraries. It's possible to install these on a 64-bit system, but if you can find what distro it was meant to run on, it might be easiest to install that in a VM. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --
Re: [Hampshire] Testing your code with CircleCI - 6pm Thursday 4th August, Southampton Uni
Thanks Andy! Would anyone on this list be interested in doing a talk for a future meeting? We're loosely focussed on Python, but we'd be very happy to hear about other technologies that are useful for Python programmers, interesting applications, and so forth. :-) Best wishes, Thomas On Fri, Aug 5, 2016, at 12:34 PM, Andy Random via Hampshire wrote: > > Thanks Thomas, > > It was an interesting meeting. > > CircleCI looks like quite a nice way to do automated testing on open > source projects without having to do the work to set up your own CI > infrastructure. > > Andy > > On Fri, 29 Jul 2016, Thomas Kluyver via Hampshire wrote: > > > Hi all, > > > > The next Southampton Python User Group talk will be a bit more hands on; > > it's best to bring a laptop if possible: > > > > Continuous Integration with CircleCI > > > > Date: 6 p.m. 4th August 2016 > > Venue: Nuffield Theatre Room 1083 (6/1083) > > Speaker: Ryan Pepper, Alvaro Perez-Diaz, Uni of Soton > > > > As usual, refreshments will be provided before the talk, and everyone is > > welcome to join us in the pub afterwards. > > > > There will also be a chance to give brief lightning talks - perhaps > > about other tools for testing code.

[Hampshire] Testing your code with CircleCI - 6pm Thursday 4th August, Southampton Uni
Hi all, The next Southampton Python User Group talk will be a bit more hands on; it's best to bring a laptop if possible: Continuous Integration with CircleCI Date: 6 p.m. 4th August 2016 Venue: Nuffield Theatre Room 1083 (6/1083) Speaker: Ryan Pepper, Alvaro Perez-Diaz, Uni of Soton As usual, refreshments will be provided before the talk, and everyone is welcome to join us in the pub afterwards. There will also be a chance to give brief lightning talks - perhaps about other tools for testing code. If there's something you'd like to tell people about, let me know! Continuous integration (CI) is an integral part of modern software development. It is very useful to check that changes have not broken features in software in an unexpected way, and it would be very rare to find software developers based in companies not using at least some form of regular testing to ensure that regression does not occur. Major scientific software projects such as Numpy, Scipy and Jupyter are good examples of how to use CI in practice. In this talk, we'll give a brief introduction to continuous integration, how it can be used in scientific software development, and demonstrate how to set up CircleCI to automatically test an open source project which is written in Python and stored on GitHub. Bring a laptop with you if possible, to get the most out of the talk. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

[Hampshire] Southampton Python User Group
Hi all, We're starting up a Python user group in Southampton, and I thought there might be some overlap of interests with this list. Our next meeting is at 6pm on Tuesday (5th July), when we'll be hearing from Robin Wilson about how he wrote Python code in one weekend to process millions of mobile phone data records after the Nepal earthquake last year. When: 6pm, Tuesday 5th July Where: University of Southampton, Murray Building (Building 58), Room 1023 - see http://maps.southampton.ac.uk/ http://southampton-python.github.io/ There will be refreshments provided beforehand, and we'll go to a pub after the talk. We'll also give anyone the chance to do a five-minute lightning talk. I'm not sure what's OK on this list, so my apologies if this is off topic.
