Laptops Old and New

Posted in Biographical with tags , , , on July 11, 2024 by telescoper

At long last the sad story of my laptop is coming to a close. This morning I collected a brand new machine from IT Services in Maynooth and returned the one I’ve had on loan since last week. I took the new machine home, hastily set it up, and installed Zoom on it, so I could do this afternoon’s telecon. Since that call finished I’ve been installing other necessary things (such as Slack), generally setting it up and connecting it to various accounts here and there. I still haven’t managed to get it to talk to my printer though.

The demise of my old machine has been a long, drawn out affair. The machine failed when I got back to Barcelona from Rome last month. I managed to resurrect it a couple of days later, but it was working only intermittently and even when it did it was very slow indeed. Last week it failed completely so I took it to IT Services and was without a machine until I borrowed a new one on Friday. The issue with the old one being fairly terminal I ordered a replacement on Monday. Today (Thursday) I got the new laptop – which is nice – and returned the one I had borrowed. The old laptop is still with the technical folks who are trying to retrieve my data from the hard disk the failure of which was behind all the problems, or so I’m told.

Although I handed over my old machine they didn’t need the power supply, which is a standard one of which they had plenty. Since the new laptop came with its own, identical to the old one, so I am now up by one power supply. Something I should have done ages ago was to get a spare power supply so I could leave one in the office to avoid having to carry it to and from home. That’s now been sorted for me.

I got my old laptop in 2018, so it is about 6 years old and therefore out of warranty. I suppose I should have thought about replacing it anyway, but I’ve actually been lucky with laptops. I have two much older that both still work.

I bought one of them – from Dell, like my new one – when I was at Queen Mary. It still runs Windows 95 and I never connect it to the internet, but I find it good for typing things on as the keyboard has a good feel to it though it is rather heavy. The other one – from Toshiba – dates from 2001 and is much lighter than the other. It also still works, running Windows 2000*, though I don’t use it very often, primarily because the wi-fi antenna no longer works.

P.S. When people ask me whether I’ve upgraded from Windows 10 to Windows 11, I always say that I’m way ahead of them – I’m already on Windows 2000!

Counting the Cost of Gold Open Access

Posted in Open Access with tags , , , , , , , , , on July 10, 2024 by telescoper

If you’re interested in how Article Processing Charges (APCs) have changed over the past five years, the data from six major publishers are now available accompanied by a paper on the arXiv with the abstract:

This paper introduces a dataset of article processing charges (APCs) produced from the price lists of six large scholarly publishers – Elsevier, Frontiers, PLOS, MDPI, Springer Nature and Wiley – between 2019 and 2023. APC price lists were downloaded from publisher websites each year as well as via Wayback Machine snapshots to retrieve fees per journal per year. The dataset includes journal metadata, APC collection method, and annual APC price list information in several currencies (USD, EUR, GBP, CHF, JPY, CAD) for 8,712 unique journals and 36,618 journal-year combinations. The dataset was generated to allow for more precise analysis of APCs and can support library collection development and scientometric analysis estimating APCs paid in gold and hybrid OA journals.

There’s even an interactive data explorer here, at which link you can also find this very informative summary graphic:

Surprise, surprise: the vast majority have gone up!

These figures apply to Gold and Hybrid Open Access publications, but not to Diamond Open Access journals which are free to both authors and readers and avoid these rip-off charges. In my opinion research institutions would be much better off investing in Diamond Open Access publishing than sending their hard-earned cash to profiteering outfits such as Elsevier.

First Flight of Ariane 6

Posted in Uncategorized with tags , on July 9, 2024 by telescoper

Five minutes to go!

Update: it all seemed to go very well, but the timing of the launch was badly planned by the EuropeanSpaceAgency, as it clashed with the semi-final between Spain and France in the European Championship.

Who had one of these as a kid?

Troll Doll

I had a toy like the one shown above when I was a little kid in the 1960s. We always referred to it as a “Gonk” but I am reliably informed that it is actually a Troll Doll.

One of the things I remember about growing up in Newcastle upon Tyne back then was that there were lots of visitors from Norway in the town at weekends. They came by ferry from Oslo and Bergen to do shopping. For that reason I assumed my Gonk Troll was Norwegian, but these dolls seem to have originated in Denmark.

You live and learn.

Ben Webster in Copenhagen

Posted in Jazz with tags , , , , , on July 9, 2024 by telescoper

The great tenor saxophonist Ben Webster moved to Europe in 1964 and spent much of the rest of his life in Denmark until he passed away in 1973. After his cremation, his ashes were interred in the Assistens Kirkegård in Copenhagen; I visited his grave many moons ago:

That’s a bit of context for a beautiful clip I just stumbled across and couldn’t resist sharing here. It was filmed in Copenhagen in 1965 in the intimate surroundings of the apartment of Danish bass player Niels-Henning Ørsted Pedersen (who plays on the track), with Ole Steenberg on drums and Kenny Drew on piano. Kenny Drew is also buried in the Assistens Kirkegård, in a grave not far from Ben Webster’s.

This is a fine demonstration of Webster’s beautifully tender way of playing ballads, in this case George Gershwin’s Someone to Watch Over Me.

Opinion Polls, Exit Polls and Election Results

Posted in Politics with tags , , , , , , , , , on July 8, 2024 by telescoper

It has been quite an eventful week for voters either side of the English channel. In the United Kingdom, Keir Starmer’s Labour Party were victorious in the General Election, turfing out the Tories after 14 years of misrule, while in France a left-wing coalition managed against the odds to beat Marine Le Pen’s fascist National Rally into third place in their runoff election. In both elections tactical voting clear played a big role. In France many third-placed candidates of the centre or left stood aside to help defeat the Far Right. What happens now with regard to forming a government is anyone’s guess, even for people who know far more about French politics than me.

In the runup up to the UK general election, opinion polls had Labour much further ahead in terms of popular vote. As it turned out, however, Labour won 411 seats on a share of the vote of just 33.7% compared to the Conservatives 23.7% and a smaller number of votes than in 2019 when they won just 202 seats. The UK system is not proportional – and doesn’t pretend to be – so this kind of outcome is not surprising. Pundits have rightly pointed to the fact that the far-right Reform party got 14.3% of the vote which undoubtedly took seats from the Tories, but only managed 5 seats and that Labour profited greatly from the collapse of the SNP vote in Scotland.

There are other factors, however. One is that the turnout was 59.9%, well down on 2019 (67.35). That may well be partly due to voters generally not being enthused. But there may be more to it than that. The last time the turnout was below 60% in a UK general election was in 2001. In that year, Labour were miles ahead in the opinion polls so I suppose many Labour voters thought the result was a foregone conclusion and didn’t bother to turn out. It seems likely to me that there was a similar effect on the Labour vote this time. Rather than merely predicting the final result, opinion polls often influence it.

Another factor is that there may have been higher levels of tactical voting, especially with Labour voters switching to the Liberal Democrats to remove the Tory. That might account for why the LibDems did so well. Opinion polls play a role in this too. Yet another is that Labour lost several seats to Independents, standing against the stance on Gaza, and former Labour leader Jeremy Corbyn won his seat standing as an Independent.

That brings me to the exit polls in the UK and France. Here the projections, the first released at 10pm on Thursday and the second at 9pm on Sunday:

Both are pretty accurate, but I’ve always been annoyed by the way the UK exit poll projection (left) is presented as a point estimate without any indication of the uncertainty (which must be considerable, especially for the smaller parties). The final results were Labour 411, Conservative 121, Lib Dem 72, Reform 5, SNP 9, Plaid Cymru 4, Green 4.

The French method of presenting the results (right) is much better in my opinion. In this case the results were 182, 168 and 143 respectively – all within the range presented.

I have to say that I greatly prefer the voting system used here in Ireland to those deployed in either France or the United Kingdom. Elections here are held under Proportional Representation (Single Transferable Vote) which seems to me a very sensible system. One ranks the candidates in order of preference; you can rank all the candidates or just some. In the system employed here in Ireland, votes are progressively reallocated in various rounds until one ends up with the top n candidates to fill the available seats. The STV system involves a quota for automatic election which is N/(m+1) + 1 votes, where N is the number of valid ballots cast and m is the number of seats in the constituency.  To see why this is the case consider a four-seat constituency, where the quota would be 20% of the votes cast plus one. No more than four candidates can reach this level so anyone managing to get that many votes is automatically elected. Surplus votes from candidates exceeding quota, as well as those of eliminated candidates, are reallocated to lower-preference candidates in this process. This system returns representatives with a local constituency connection but is also (approximately) proportional.

One problem with the First Past The Post system deployed in the UK is that if a Reactionary party (Reform) gets 5 seats while a Progressive party (Green) gets only 4, the former gets all the press coverage and the latter gets none..

P.S. I didn’t vote in the UK general election, but the four constituencies in which I lived before moving to Ireland (Cardiff West, Brighton Kemptown, Broxtowe, and Bethnal Green & Stepney) all voted in Labour MPs.

All-Ireland Hurling Semi-Final Weekend

Posted in GAA with tags , , on July 7, 2024 by telescoper

Just a quick post to mention that this weekend saw the semi-finals of this year’s All-Ireland Senior Hurling Championship at Croke Park.

Yesterday, after playing very poorly against Kilkenny in the first half,  Clare staged an epic comeback to create an exciting finish, eventually to win by two points (0-24 to 2-16).

Today’s semi-final was even better, with Cork pulling out all the stops against Limerick in the second half in a match that was played at an extraordinary tempo even by the standards of hurling. Cork ran out deserved winners by 1-28 to 0-29. Once again, only two points separated the sides.

Limerick were bidding to win their 5th All-Ireland championship in a row, but they have to settle for four, as the final in two weeks’ time will be between Cork and Clare.

Call for Editors at the Open Journal of Astrophysics

Posted in Open Access with tags , , , , , , , , , , , , , on July 7, 2024 by telescoper

Just over halfway into 2024 the number of papers submitted to the Open Journal of Astrophysics continues to rise, as demonstrated by this nice graphic which shows the submission stats for the last five years:

The increasing number of articles is of course very welcome indeed, but it is increasing the load on our Editorial Board and that includes me! We’re therefore looking for volunteers to join the team, in any area of astrophysics. As a reminder, here are the areas we cover, corresponding to the sections of astro-ph on the arXiv:

  1. astro-ph.GA – Astrophysics of Galaxies. Phenomena pertaining to galaxies or the Milky Way. Star clusters, HII regions and planetary nebulae, the interstellar medium, atomic and molecular clouds, dust. Stellar populations. Galactic structure, formation, dynamics. Galactic nuclei, bulges, disks, halo. Active Galactic Nuclei, supermassive black holes, quasars. Gravitational lens systems. The Milky Way and its contents
  2. astro-ph.CO – Cosmology and Nongalactic Astrophysics. Phenomenology of early universe, cosmic microwave background, cosmological parameters, primordial element abundances, extragalactic distance scale, large-scale structure of the universe. Groups, superclusters, voids, intergalactic medium. Particle astrophysics: dark energy, dark matter, baryogenesis, leptogenesis, inflationary models, reheating, monopoles, WIMPs, cosmic strings, primordial black holes, cosmological gravitational radiation
  3. astro-ph.EP – Earth and Planetary Astrophysics. Interplanetary medium, planetary physics, planetary astrobiology, extrasolar planets, comets, asteroids, meteorites. Structure and formation of the solar system
  4. astro-ph.HE – High Energy Astrophysical Phenomena. Cosmic ray production, acceleration, propagation, detection. Gamma ray astronomy and bursts, X-rays, charged particles, supernovae and other explosive phenomena, stellar remnants and accretion systems, jets, microquasars, neutron stars, pulsars, black holes
  5. astro-ph.IM – Instrumentation and Methods for Astrophysics. Detector and telescope design, experiment proposals. Laboratory Astrophysics. Methods for data analysis, statistical methods. Software, database design
  6. astro-ph.SR – Solar and Stellar Astrophysics. White dwarfs, brown dwarfs, cataclysmic variables. Star formation and protostellar systems, stellar astrobiology, binary and multiple systems of stars, stellar evolution and structure, coronas. Central stars of planetary nebulae. Helioseismology, solar neutrinos, production and detection of gravitational radiation from stellar systems.

We are looking for experienced scientists in any of these areas, and it would indeed be useful to have people who can cover a range of subjects (as some of our existing editors do), but there are two specific topics that have seen a big increase recently: (a) galaxy formation simulations (especially involving hydrodynamics) covered by astro-ph.CO; and (b) galactic dynamics, covered by astro-ph.GA. The latter increase is driven Gaia data, an immensely rich source for discovery science.

Since we don’t charge authors or readers we can not offer payment to Editors but it is nevertheless a way of providing a service to the community.

Please get in touch either through the Open Journal website here, or through a message Mastodon here, BlueSky here, or Facebook here. You could even send a message through this form:

Two New Publications at the Open Journal of Astrophysics

Posted in OJAp Papers, Open Access, The Universe and Stuff with tags , , , , , , , , , on July 6, 2024 by telescoper

My own laptop is still with the menders but I’ve managed to borrow one until I get it back so I don’t get too far behind. Anyway, it’s Saturday morning, and once again time to post another update relating to the  Open Journal of Astrophysics.  Since the last update we have published two more papers, taking  the count in Volume 7 (2024) up to 54 and the total published by OJAp up to 169.  There was one less arXiv update than usual last week, owing to the holiday on July 4th, so a couple of papers have been delayed.

The first paper of the most recent pair, published on July 3rd 2024,  is “Recovering 21cm Monopole Signals Without Smoothness” by Rugved Pund & Anže Slosar (Stony Brook, NY, USA) and Aaron Parsons (Berkeley, CA, USA) . This paper presents a new method for identifying the ‘Dark Ages’ trough contribution to the monopole of the 21cm radiation background that does not rely on the assumption that the spectrum is smooth. The paper is in the folder marked Cosmology and NonGalactic Astrophysics.

Here is a screen grab of the overlay which includes the abstract:

 

 

You can click on the image of the overlay to make it larger should you wish to do so. You can find the officially accepted version of the paper on the arXiv here.

The second paper, also published on 3rd July, has the title “LtU-ILI: An All-in-One Framework for Implicit Inference in Astrophysics and Cosmology”. There are fifteen authors with primary affiliations as follows: Matthew Ho (IAP, Paris, France), Deaglan J. Bartlett (IAP, Paris, France), Nicolas Chartier (Seoul National University, Korea),  Carolina Cuesta-Lazaro (Cfa, Harvard, USA),  Simon Ding (IAP, Paris, France), Axel Lapel (IAP, Paris, France), Pablo Lemos (Université de Montréal, Canada), Christopher C. Lovell (University of Portsmouth, UK),  T. Lucas Makinen (Imperial College, London, UK), Chirag Modi (Flatiron Institute, NY, USA), Viraj Pandya (Columbia University, NY, USA), Shivam Pandey (Columbia University, NY, USA), Lucia A. Perez (Flatiron Institute, NY, USA), Benjamin Wandelt (IAP, Paris, France),  and Greg L. Bryan (Sorbonne Université, Paris, France).

This paper, which is in the folder marked Instrumentation and Methods for Astrophysics, presents a suite of software for rapid, user-friendly, and cutting-edge inference using machine learning in astrophysics and cosmology. The software can be found on Github here.

Here is a screen grab of the overlay which includes the abstract:

That concludes this week’s update. No doubt I’ll have more for you next week!

Interlude

Posted in Uncategorized on July 3, 2024 by telescoper

I finally decided to take my ailing laptop to the computer hospital where I hope it can be restored to health reasonably soon (or put out of its misery and replaced with a new one). In the meantime, however, I will be taking a break from blogging.

Normal services will be resumed as soon as possible but, for the time being, there will now follow a short intermission.
