There’s no good reason for them to make these screws left-hand thread, other than to make you strip the soft plastic they’re set into if you have the temerity to try to take your own property apart. Manufacturers really seem to hate people taking their gear apart, but I’ve never come across Olympus’s sort of craftiness before. I’ll show you where these blighters are later. WARNING – an Olympus E-PM1 camera has some LEFT-HAND thread screws. You can do useful stuff without providing payment details □ Well done Ordnance Survey! Initially I thought they had stiffed freebie cheapskates like me by demanding a Premium API, but no. The API dashboard shows you your usage OS API dashboard The documentation is pretty rough and ready, and note that at the time of writing if you simply implement their code example with a non-premium API you get a blank maps with just the OS logo in the bottom left corner, which can lead to much head-scratching and WTF? You now get to zoom in and get Explorer-level detail, and the free data usage is easily enough for a hobby website or blog unless you get slashdotted. Zoom in and you get Explorer 1:25000 detail. OS Openspace is no more, it is now called OS OpenData.Īvebury stone circle in Wiltshire. I used this for mapping on a website about standing stones. The OS used to have a way for people to feature Landranger maps on websites which was called OS Openspace. As taxpayers we paid for it, but unlike the enlightened approach the US has to government collected data, which is generally in the public domain 1, the OS has had a Gollum-esque relation to letting the great British public use their map data, and didn’t let their precious out of expensive pricing plans. UK Ordnance Survey maps are lovely, particularly the Landranger and Explorer series, but they are dear, and you haven’t been able to use them online for a while. It’s not that obvious to me what advantage UEFI gives me with a machine with a whopping 32Gb of disk space which is far from the 2Tb limit UEFI is supposed to fix, so legacy is fine with me.Ī disadvantage of linux on a laptop, apart from the general gangly geeky oddballness of linux on the desktop as opposed to on the server is battery life is not optimised so well.Ĭontinue reading “HP Stream 11 lives again with Xubuntu” Author richard Posted on ApCategories amateur radio, repair, technology Tags linux 4 Comments on HP Stream 11 lives again with Xubuntu UK Ordnance Survey lets us display Landranger and Explorer maps on the web But first I had to switch off the UEFI BIOS. Which is indeed great, and took me from there. If you don’t already know how to install Xubuntu, then please read this great tutorial, which applies as much to Xubuntu as to Ubuntu. I found the install instructions for Xubuntu hard to find and sketchy, but they are good enough to feature this hint I uses Xubuntu LTS 20.04, downloading the iso and putting this onto a USB stick using balenaEtcher. It was surprisingly easy to load once I quit trying to install on the UEFI BIOS. The Ubuntu drivers seem to have fixed that now However, I had heard bad things about trying Linux on the HP stream, because the Wifi card is very proprietary. I had already run the FLdigi and WSJT-X software on the HP Stream in Windows so I knew it was capable of decent performance, better than the Pi4 which struggles a bit to decode WSJT-X in a reasonable time. It’s bad enough connecting the computer to the radio via analogue audio connectors 1, having to connect the Pi plus screen to a Bluetooth keyboard plus some sort of battery to USB-C power contraption gets a bit much in the field although it all works fine on the bench. I had been tinkering with a Raspberry Pi4 for amateur radio field use, but wrangling a Pi in the field for things like SOTA is a mess, because a Pi plus all the odds and sods you need to make it work is a collection of parts flying in loose formation, and unlike a DC3 they don’t always work well together. I did like the light weight and silent operation, but the overall gutless performance and slower and slower startup was bad. It’s a shame, because it’s otherwise serviceable, but totally non-upgradeable – the ‘hard drive’ is an eMMC soldered to the board. Pretty soon I had to use an outboard hard drive to be able to update windows, and by about 2019 even that didn’t work. And it had Windows 10, and 32Gb is only just enough to get Windows on. It was a bad move from the get-go, because the hard disk is only 32Gb.
