Machine-based Censorship

Posted in Biographical with tags , , , , , , , on November 25, 2024 by telescoper

A very noticeable manifestation of the rise of so-called Artificial Intelligence has been the use of AI bots in censoring posts. The most recent example of this I’ve seen was on Saturday when I wrote a post about the general election candidates for my constituency, Kildare North. As usual when I write an article here it gets posted automatically on a variety of other platforms, including LinkedIn. However, Saturday’s post was blocked:

The powers that be did not tell me which of the “Professional Community Policies” that post might have violated so I looked through them all and couldn’t find any plausible reason for blocking that post. I can only assume some defect in the algorithm deployed by LinkedIn had been triggered wrongly. Unfortunately, all this is run by machine so there is no possibility of appeal.

I’ve noticed quite a few bizarre things like this over the past few weeks. The worst offender when it comes to random censorship is Meta (which runs Facebook, Instagram and Threads). I have been posting content automatically on Meta platforms, Facebook and Threads. Recently, however, Meta’s AI algorithm has gone berserk. A couple of weeks ago it blocked this post (about the Edgeworth family) on the grounds that it violated rules concerning “nudity or sexual activity”. Heaven knows how it decided that; you can read the post yourself. I defy you to find any nudity or sexual activity, or reference thereto, or link to any post that mentions such things, anywhere in it!

When I appealed the decision I got this.

Truly bizarre.

More recently, it blocked this post (one of my regular weekly updates for OJAp) on the grounds that it was identified as spam. I can see the need for an automatic screening given the huge volume of posts, but the problem is that my facebook feed is full of actual spam that gets through these filters while innocent posts get blocked. In other words the algorithm is crap. If you ask for a review of the decision, all Meta does is run the algorithm again – with the same results, which is a waste of time.

The algorithm that screens comments on this blog for spam has also been playing up, with some comments from regular contributors being tagged as spam.

None of these is in itself of any consequence to me personally, not least because I’m not trying to run a business using these platforms. However, such AI engines are being deployed nowadays in a huge range of contexts primarily in order to save money. No doubt such processes do save money, but if they are based on poorly constructed algorithms – which they seem to be – the consequences could be dire. Imagine the horror of a health service based on poorly trained AI…

Social Media Better than Meta

You may or may not know that these blog posts appear automatically on various social media platforms.

I have been posting content automatically on Meta platforms, Facebook and Threads. Recently, however, Meta’s AI algorithm has been randomly blocking posts. A couple of weeks ago it blocked this post (about the Edgeworth family) on the grounds that it violated rules concerning “sexually explicit content”. Today it blocked this post (the weekly update for OJAp) on the grounds that it was identified as spam. I can see the need for an automatic screening given the huge volume of posts, but the problem is that my facebook feed is full of actual spam that gets through these filters while innocent posts get blocked. In other words the algorithm is crap. If you ask for a review of the decision, all Meta does is run the algorithm again – with the same results, which is a waste of time.

I haven’t got time to waste on such stupidity so I will shortly be deactivating automatic posts to Facebook and Threads; these generate very little traffic for me anyway.

There are, however, plenty of alternative ways of following this blog. You can subscribe by email or by RSS feed for a start. On other social media platforms I recommend the federated version on Mastodon here:

https://telescoper.blog/@telescoper.blog

They also appear on my personal Mastodon account here:

https://mastodon.social/@telescoper

Posts also appear on LinkedIn here:

https://www.linkedin.com/in/peter-coles-911912216/

and on my BlueSky account:

WordPress has just set up an automatic integration with BlueSky, on which I now have over 3000 followers, which is nice, but any one of these is better than Meta!

In the Dark on Social Media

Posted in Biographical, Politics with tags , , , , , , on August 12, 2024 by telescoper

It’s almost a year since I deactivated my Twitter account. Or should I call it X? Anyway, it doesn’t matter because I don’t use it any more. Over the past few weeks it seems quite a few more – especially in the UK – have had enough of the antics of Elon Musk (aka Space Karen), especially with his attempts to fan the flames of the recent Farage riots by spreading misinformation. The first thing I noticed was that my BlueSky account was suddenly getting quite a lot of new followers. I now have about 850, still a long way short of the over 7000 I used to have on Twitter, but the level of engagement is far higher. That’s because the algorithm Space Karen introduced on X makes it difficult for your own followers. let alone anyone else, to see your tweets. The one disadvantage of BlueSky is that it doesn’t have an API that allows me to post directly from this blog when I publish a post, so I have to copy the URL by hand.

I also have an account on Mastodon where I have over 1200 followers and similarly good engagement. When I first started there a couple of years ago it didn’t have a WordPress API but it does now, so everything I write here gets posted automatically on my feed. Not only that, this blog is now also now fully federated which means that there is an autonomous feed for the blog posts. Not just a link to each post, as the API produces, but the whole post. This is a nice feature because if I change a post on this WordPress platform it automatically gets changed on the Mastodon feed.

I also have a Facebook Page on which these

And now there’s Threads, which is like a version of Twitter bolted onto Instagram. When this first came out last year it wasn’t available in the EU for data protection issues so I didn’t bother with it. I only just found out at the weekend that has been available since December 2023 but I wasn’t paying much attention to social media then so didn’t catch the news. Anyway, since I already have a (very quiet) Instagram account so I set up a Threads account which you can find here if you like that sort of thing. My first impressions of Threads are not very favourable, but let’s see how it goes. At least it’s not as bad as Twitter. I still think it is indefensible that my employer, along with most other universities, has decided to maintain a presence on that site.

The Age Thing

Posted in Biographical, Education with tags , , , , , on January 2, 2024 by telescoper

When I was younger, so much younger than today, I thought I would hate getting old. Now that I’m sixty though I have to say in all honesty that it’s not too bad at all. I could do without the arthritis, of course, but that’s more of an inconvenience than anything else. I am also fortunate to be comfortably off and in a secure job, with the prospect of a decent pension. When I was younger I was frequently under stress, with bouts of insomnia and other issues. Although I am subjected to a bit of aggravation now and then, I seem to have learnt to deal with it better.

I think part of this is that as I’ve got older I’ve become more resistant to peer pressure. Nowadays I go out only when I really want to, and do only what I want to do. Gone are the days when friends used to drag me out to places I didn’t really want to go to. I used to go because I thought people would label me as ‘boring’ if I didn’t. Nowadays, I don’t mind being called boring. I may be boring to you but I am rarely ever bored. I always find plenty to occupy myself.

Another thing that helps is working in a University, which is a good way of being surrounded by interesting young people. So many people of my age seem to resent the young, to the extent of criticizing virtually everything they do. I find the vast majority students friendly, hard-working and engaged, although they have to put up with much more than I had to when I was in their situation.

Teaching physics is interesting because the current generation of undergraduates has to learn a lot of what I had to when I was a student. Every year therefore provides a reminder of the time when I was the age of the new intake, as many of their educational and social experiences are similar. Of course not all. When I was an undergraduate we had no internet or anything like that. There were no social media, either. 

Students these days seem to like using Instagram. I do have an account on Instagram but it is very quiet, probably because I’m not very good at it. Some students follow me there, but I have been told that it would be “inappropriate” to follow them back. That’s probably fair, but I do worry that I appear rude for not following back. It’s not that I’m snobbish or anything. I just feel that I would be intruding, in much the same way as if I wandered into a bar full of students I know. It’s not that I don’t like them, just that I find it awkward (as I’m sure they do). Not having had Instagram when I was young, I suppose I just don’t really understand the etiquette.

One of the things about Instagram is that people do sometimes share quite personal things, and sometimes things that might be quite compromising in a work context, e.g. pictures of themselves in a  state of inebriation. I suppose that’s why it’s a rather contentious issue whether a member of academic staff in a University should or not be “friends” with their undergraduate students on social media. Indeed, this is the official advice given by some institutions to staff. Most wouldn’t have a problem with having social media interactions with their graduate students, though. The nature of the relationship between a PhD student and supervisor is different from that between an undergraduate and a lecturer.

There is a point on social media where professionalism might be compromised just as there is in other social interactions. The trouble is knowing precisely where that boundary lies, which is easy to misjudge. I’ve never felt that it was in any way improper to be friendly to students. Indeed I think that could well improve the students’ experience of education. If the relationship with staff is too distant students may not  feel comfortable asking for help with their work, or advice about wider things. Why should being “professional” mean not treating students as human beings? One can take friendliness too far, however. There have to be some boundaries, and intrusive or demanding behaviour that makes students uncomfortable should be avoided.

I realize I have digressed into social media. Aside from that, though, I’m sure much of student was similar in my day. I’m pretty sure that neither the subject of physics nor students of physics have changed that much over the years. The only difference from my perspective is that every year they look younger! That’s the other side of the coin: the students remind you of your younger self, but not in such a way as to delude you into thinking that you’re still the same person! I think that’s the one thing I’ll miss when I retire, hopefully in the not-too-distant future.

All of this is a roundabout way of saying that I don’t mind getting old. In fact, I feel that my whole life so far has been practice for this.

Euclid in the Media

Posted in Euclid, The Universe and Stuff with tags , , , , , on December 3, 2023 by telescoper

Yesterday came across the above “infographic” – as I’m told such things are called – showing the media traffic generated by last month’s Early Release Observations from the ESA Euclid mission. Some quite interesting facts emerge from it. The new observations were released n 7th November, hence the big spike in the left hand panel on that date.

I see that about 31% of the activity was on Twitter, which I am no longer on, with a slightly smaller amount on Facebook. Overall, social media account for about 60% of the “reach”, with mainstream media (including print, online, and TV/Radio) languishing far behind. Blogs (presumably including this one) account for a mere 1%.

The breakdown by country is interesting too; the table shows only EAS member states. The UK is way out in front, no doubt because BBC News ran a major item on the day of the release. France, Germany, Italy and Spain all have major scientific involvements in Euclid and correspondingly active public engagement activities.

I was pleasantly surprised at the significant amount of interest in Ireland, given that some bigger countries with far greater scientific involvement in Euclid (e.g. Denmark and The Netherlands) generated so little. As the only member of the Euclid Consortium in Ireland I could try to pretend that this was all down to me, but I rather think it’s more likely to be a result of the fact that many Irish people read the UK media so some of the Irish traffic could be spillover from the big UK spike. Still, I think one can interpret this as meaning that the Public in the Republic have an appetite for news about space, something that we have certainly noticed when organizing events in Maynooth.

I thought I’d mention another nice thing. Here is one of the PR images produced by ESA about the early release observations. The point about Euclid is that to achieve its science goals it has to have extremely good optical quality across a very wide field of view. The systems are currently being tested and fine-tuned to see how good their performance actually is, but so far it’s looking good.

The main thing that caught my eye, however, is the collection of little flags along the bottom. How nice it is to see Ireland’s among them!

Cold Turkey Twitter

Posted in Biographical with tags , , , , on October 8, 2023 by telescoper

I’ve seen quite a few articles (such as this one on LinkedIn) by academics lamenting the terminal decline of the website formerly known as Twitter, so I thought I’d add my thoughts. I come to bury Twitter, not to praise it.

I joined Twitter in 2009 or thereabouts. Over the years, I accumulated around 7300 followers. Not an enormous number by any standards, but a reasonable one. I used the platform only partly for academic matters. I found it in turns amusing and annoying. I dealt with the latter aspect largely through liberal use of the block facility. I admit I found the recreational aspect mildly addictive.

In recent times, however, Twitter (or X as we’re now supposed to call it) has turned to shit. Since Elon Musk took over, users are basically silenced unless they pay for a blue tick, the social media equivalent of buying a megaphone for use in a library. The API that allowed me to post there from WordPress was axed, which was an additional pain. Add the constant stream of promoted tweets and other ads to the deluge of unmoderated bigotry, and the result is unbearable.

I deleted my Twitter account completely at the end of August and haven’t looked back. Since I’d spent a lot of time there, a number of friends expressed scepticism that I’d manage to do it cold turkey like that, but it was no problem, and I have no withdrawal symptoms.

I now much prefer Mastodon, where I’ve had an account for about a year. I have just over a thousand followers there, just one seventh of the number I had on Twitter, but much higher levels of engagement. More importantly, it’s far more civilized. I’ve only had to block one person. WordPress has also introduced an autopost to Mastodon, so every blog post I write appears there automatically.

I have also joined BlueSky. This site is still in development and, for the time being, is by invitation only, so is rather quiet. In recent weeks, however, I’ve noticed quite a large number of astronomers arriving there, so it is an interesting place to be. I have some spare invites, actually…

Just say no to Twitter. It’s not worth it.

Social Media and Academia

Posted in Biographical with tags , , , , on July 11, 2023 by telescoper

I saw the post attached below and thought I’d share it here. I don’t have as many followers on social media as the author of the post and I’ve never thought of confining this blog to purely research topics. In terms of academic matters I never thought Twitter was useful for anything other than sharing web links. I’m glad that I stuck to the longer form of blogging represented by this site.

Nevertheless I do have similar experiences of Twitter to those described in the article. It has indeed turned to shit. Since Elon Musk took over, you are basically silenced unless you pay for a blue tick, the social media equivalent of buying a megaphone for use in a library. Add the constant stream of promoted tweets and other ads and it really is a bad experience all round. I locked my Twitter account some time ago.

While I still post on Twitter, I now much prefer Mastodon. I have about 1/8 the number followers there, but much higher levels of engagement and it’s far more civilized. WordPress has now introduced an autopost to Mastodon, incidentally. The autopost to Twitter is no longer supported. If anyone wants to follow me on social media I’d recommend finding me on Mastodon.

(I’ve also joined BlueSky, but so far that is rather slow. I won’t be joining Threads, as that isn’t available in the civilized world (i.e. the European Union) owing to data protection issues.)

On Mastodon…

Posted in Biographical with tags , , , on October 31, 2022 by telescoper

The recent takeover of Twitter by Elon Musk, and the likely removal of content moderation with all that implies for increased toxic behaviour, has led me to reconsider my use of social media. I know I’m not alone in this either. Over the weekend I noticed quite a few of my friends quitting Twitter for Mastodon so I thought I’d give it a go.

Mastodon is a microblogging service with a similar look and functionality to Twitter but there are some big differences. For a start Mastodon is not run from a single website. It is a distributed network of servers around the world running open-source software; each server is called an ‘instance’. This means that it is not owned by a single individual or company and the different instances can have different moderation policies. Any person or organization capable of operating a server running the software, and willing to take on the legal issues, can federate to the overall network.

For another thing it is community led, with each instance run by volunteers. It is free of charge, has no advertising , so none of those annoying ‘promoted tweets’, nor any creepy algorithms trying to influence your behaviour, and above all does not exist to serve the ego of a billionaire owner with sociopathic tendencies.

Then there is the moderation policy. I joined the original server `mastodon.social’ (where I am the usual @telescoper) which has the following rules:

Hopefully this will deter those who spend all their time on Twitter sending abuse from joining Mastodon. This server is based in Germany, hence number 5. Although I think it was included for other reasons, it reminds me that defamation is a criminal offence in Germany, punishable by a prison sentence. A certain individual who has a habit of posting defamatory messages about me on Twitter should bear this in mind…

Anyway, I’ve only just got onto the platform and am still finding my way around. I only have a handful of followers, compared to the 7000+ I have on Twitter. For the time being I’m still on Twitter, but if it goes well then I intend to leave that to the trolls and bigots. I’m sick of spending so much time blocking objectionable people and seeing decent people abused.

P.S. One thing I think would be handy would be an API that allows me to publish these blog posts automatically on Mastodon like I do on Twitter, but I haven’t seen one yet…
