hpr3954 :: Sedating HPR at the Steading

MrX and Dave Morriss have lunch and record another chat

Duration: 01:14:22

Introduction

Hosts:

We recorded this on Sunday September 3rd 2023. We met in person again, and as before first visited the pub called The Steading where we had lunch. Then we adjourned to Dave's car in the car park, and recorded a chat.

The name "Steading" is another (Scots?) version of "Farmstead", and means the same. It's also an anagram of "Sedating"1, so ...

Topics discussed

  • Vaccines:
    • Dave has an appointment for COVID-19 and influenza vaccines. The new Omicron variant BA.2.86 has prompted another booster for some people.
    • Discussion of Smallpox vaccination
    • MrX has an appointment for an influenza vaccine
  • Edinburgh:
    • Dave took a trip on the recently extended Edinburgh tram
      • There is only one route, from the airport to Leith (port).
      • Older residents get free access.
    • MrX and MrsX recently walked from the centre of Edinburgh along the Water of Leith to the area where the tram terminus is at Newhaven.
  • Email:
    • Dave is using version Thunderbird 115.1.1 which is a rewrite of the original series where the API has now changed a lot.
    • Long-used add-ons now no longer work:
      • A favourite was Mailbox Alert which triggered sound alerts (or others) then mail arrived in a folder - so this could be after filtering. This was much more useful than the traditional "You have mail" type alerts.
    • Discussion of tags:
      • MrX mentions tags, meaning bits of text that can be attached to messages and used to classify them and to search for them.
      • In Gmail there are labels which can do this and these can be used to group messages regardless of folders
      • Thunderbird also has this concept which it calls tags. It comes with pre-defined tags such as Important and To Do, but more tags can be added. Any message can be given one or more tags. The filtering system can add tags as a message is processed. Searches can be performed on tags also.
      • Dave is an enthusiast of nested folders with filters to classify messages. MrX is keen on using tags for the same purpose. Dave mentioned Thunderbird's saved search feature (which he wrongly called virtual mailboxes) which can collect messages according to many criteria, including tags.
      • Some discussion about mail message storage strategies: file per message, mbox format, etc.
  • Ticks:
    • MrX's dog has brought some ticks back from recent walks.
    • Scotland seems to be a bit worse off for ticks in recent years.
    • Hikers need to protect against them and to perform checks that they are not on clothes. Wearing long socks or gaiters over long trousers can help.
    • Lyme Disease is a bacterial infection that can be passed by ticks.
    • This Week in Parasitism recently talked about an unpleasant disease caught from ticks, Babesiosis (not bacterial as Dave thought, but caused by a protozoan). This was in the USA; the disease doesn't seem to be in the UK at the moment.
    • Removal of ticks needs a tool or a fine pair of tweezers.
  • HPR changes:
    • Mentioned on the recent HPR Community News
    • Problem reports can be sent by email to admin at HPR, as messages to @hpr@botsin.space on Mastodon, and to the #hpr:matrix.org channel on Matrix.
  • Watching and listening:
    • MrX has been watching the YouTube channel Little Chinese Everywhere, recommended in the last of these chats.
    • MrX has also been listening to the BBC radio show Computing Britain. It consists of 12 15-minute episodes, from 2015, and is available as a podcast.
  • YouTube recommendations:
    • Dave:
      • Not Just Bikes:
        • A channel about cycling and city design. The channel owner is Canadian but has moved to Amsterdam for a better life for himself and his family. He highlights the differences between North American city design and the design of many European cities.
        • Example video: Even Small Towns are Great Here (5 Years in the Netherlands)
      • BicycleDutch:
        • Another channel about cycling in the Netherlands. This channel host, Mark Wagenbuur, is Dutch and does videos about cycle routes, and their development. Lots of videos made as he cycles a route. He is based in ’s-Hertogenbosch (map) and cycles in the region and to and from Utrecht.

hpr3953 :: Large language models and AI don't have any common sense

Learn how to load and run GPT-2 or Llama2 to test it with common sense questions.

Hobson and Greg are working with volunteers to develop an open source AI that we call Qary (QA for question answering). We're adding plugins to support open source large language models (LLMs) like GPT-2 and Llama2. Here's how you can use LLMs in your own Python Programs.

  1. Create a Hugging Face account:
  1. Create and copy your access token:
  1. Create a .env file with your access token string:
echo "HUGGINGFACE_ACCESS_TOKEN=hf_..." >> .env
  1. Load the .env variables in your python script using dotenv package and os.environ:
  • TIP: Use os.environ to retrieve the dict of variable values rather than dotenv.load_values- Otherwise other environment variables that have been set by other shell scripts such as .bashrc will be ignored.
  • This confused us when we were getting our GitLab CI-CD pipeline working and deploying to Render.com.
  • Each of your cloud services will have different approaches to setting environment variables.
  • This token string can be passed as a keyword argument to most of the pipeline and model classes.
import dotenv
dotenv.load_dotenv()
import os
env = dict(os.environ)
token = env['HUGGINGFACE_ACCESS_TOKEN']
  1. Find the path and name for the model on Hugging Face hub you want to use:
  • search for "llama2" in the top search bar on huggingface.co/
  • TIP: don't hit enter at the end of your search, instead click on "See 3958 model results for llama2"
  • I clicked on meta-llama/Llama-2-7b-chat-hf to see the documentation
  1. On the documentation page for your model you may have to apply for a license if it's not really open source but business source like Meta does with its AI so you can't use their models to compete with them
  • Apply for a license to use Llama2 on ai.meta.com using the same e-mail you used for your Hugging Face account.
  1. Follow the instructions on huggingface.co to authenticate your python session
  • TIP: You'll need to use the kwarg use_auth_token in the AutoModel.from_pretrained or pipeline functions.
  • And it should be set to the token from your Hugging Face profile page. The hugging face documentation says to use the token kwarg, but that never worked for me.
from transformers import pipeline, set_seed
generator = pipeline('text-generation', model='openai-gpt')
q = "2+2="
responses = generator(
    q,
    max_length=10,

[{'generated_text': '2+2= 2.2, 1.1 and'},
 {'generated_text': '2+2= 3336 miles. they'},

    for resp in responses:

Because it doesn't have the word "Civilization" in its name, this game is unfairly overlooked. It was a major achievement when released, and it is still a very rewarding game for anyone to pick up and play. There is a lot of depth to it, and it holds up well even after a couple of decades.

Archiving Floppy Disks

Summary

This show describes how I go about archiving old floppy disks. These disks date back to the early 90s when floppy disks were a common way of installing software on personal computers. They were also used as a portable storage mechanism for data files.

Equipment That I'm Using

  • IBM ThinkCentre desktop computer with a 3.5in floppy disk drive
  • Installed the 32-bit version of Slackware 14.2

Making an image of an entire floppy disk

dd if=/dev/fd0 of=filename.dsk

Making a floppy disk from a disk image

dd if=filename.dsk of=/dev/fd0

Copy files from a floppy disk

mount -t msdos /dev/fd0 /mnt/floppy
cd /mnt/floppy
cp filename /some/destination/path/filename
cd
umount /mnt/floppy
