Ça tombe bien j'en suis presque au dénouement de l'excellent bouquin de #YvonneBesson, "UN COIN TRANQUILLE POUR MOURIR" .
Das Gebiet im Süden Frankreichs diente vor 470 Millionen Jahren als Zuflucht für Arten in Zeiten globaler Erwärmung.

For the third day in a row, #Arctic #sky watchers are reporting a widespread outbreak of #polar #stratospheric #clouds. "The colors are spectacular," says Ramune Sapailaite, who photographed the display over Gran, #Norway:
"The clouds were visible in the sky all day, but the #colors really exploded just before #sunset," says Sapailaite. "I took these pictures using my cellphone."
Widely considered to be the most beautiful clouds on Earth, polar stratospheric clouds (PSCs) are rare. Earth's stratosphere is very dry and, normally, it has no clouds at all. PSCs form when the temperature in the Arctic stratosphere drops to a staggeringly-low -85 C. Then, and only then, can widely-spaced water molecules begin to coalesce into tiny ice crystals. High-altitude sunlight shining through the crystals creates intense iridescent colors that rival auroras.
During a typical Arctic winter, PSCs appear no more than a handful of times, and the first sightings usually come in January. This week's apparition marks an early start, and may herald many more PSCs to come.

Bientôt paraîtra mon premier roman édité par les Presses littéraires : "CORSE CONFIDENTIEL"
En voici la présentation en quatrième de couverture du livre :
Corse, fin des années 2000.
Le corps d’une jeune femme est découvert sur un site archéologique en cours de fouille. Meurtre crapuleux ? Crime raciste ? Règlement de compte ? L’arbre cache-t-il encore une fois la forêt ?
Les meurtres se succèdent. L’affaire prend des allures de plus en plus tortueuses mettant à vif les plaies de la société insulaire contemporaine.
Le “trio infernal” tant redouté des justiciables de la place, Jeanne Castellani procureure, Geneviève Altman commissaire de police et Olivier Pinol juge d’instruction, est bien décidé à donner un vigoureux coup de pied dans la fourmilière et ne se montre pas du tout enclin à prendre les vessies pour des lanternes. Leur détermination sans faille dérange …
Je vous tiens au courant …

Well, this has been quite an experience over the last 3 months! My Samsung Watch 5 started out in the end of December working perfectly and tracking all my exercises quite correctly from the first minute onwards, during the first month. But by the end of Jan / Beginning Feb 2023 I noticed big lags in it registering the increased heart rate, often with a few minutes of no reading, or sometimes just maintaining a non-exercise level heart rate for a third of the exercise duration (see featured image on the post).
I went through all the suggested solutions like:
* Ensuring the strap is a bit tighter for exercising
* Check firmware and apps are updated
* Check heart rate, and get reading, before starting exercise
* Rebooting watch
* And even doing a hard reset back to factory settings
So, after 2 months the watch was sent into Samsung Repairs with piles of printouts showing how long it worked perfectly, and then all the exercises since end of January that were faulty. Upon receiving the Watch back nearly a month later, it was exactly the same. I queried this with the shop, and they suggested I speak to the actual technician at Samsung. Well, it turns out the shop never sent my printouts through with the watch for the repairs and it just said the “heart rate was faulty”. That was absolutely not true as the heart rate otherwise was showing fine for non-exercises. It was suggested I take the watch in myself to Samsung repairs and discuss it, which I did. The technician explained they had already swapped out the insides, so the hardware was actually replaced. To cut a long discussion short, he suggested that seeing it did work originally, he will again reset and recalibrate it, but will install the Samsung Nov 2022 firmware, and I should not apply any updates before testing the watch.
I came home with the watch and did not even restore the last backup. I hit the exercise machine…. and …. it was still the same! I thought maybe it was the Welltory app (for HRV) that also took heart rate measurements, so I deleted that app too. I did a second day’s exercise to be sure. The second day was even worse with 99% of the exercise showing normal varying heart rate, despite me averaging around 168 bpm.
In the end I decided to buy a Polar H10 Chest Strap mainly for the following reasons:
* I get 45% discount through the medical insurance every 12 months on a device up to R6,000 (US$326) so it is way cheaper than another watch (75% if I was really good)
* It is a good 99% plus accurate, even more so than the Apple Watch I had previously
* The strap offers more detailed HRV analysis than the watch
* The H10 can be used to track one exercise on its own without needing the phone or watch nearby (and is also not affected by my switches between an Android or an iPhone)
After two non-functional exercises with the watch, I decided last night to do the firmware upgrade. It may be one release newer than I had before handing it in the second time for repairs. So, imagine my surprise after I started exercising this morning, and the watch was tracking the heart rate just perfectly. In fact, the Samsung watch was closer to the Polar chest strap than even the Fitbit Inspire 2 which I’d loaned from my wife. The watch was within 1-2 BPM, and the Fitbit about 2 to 3 BPM. The image below is what the Samsung Galaxy Watch 5 should look like when doing an exercise (it’s not perfect as it lost the reading for a very short bit, and does have a slight dip too, but it is generally correct, and certainly the tracking the start correctly).
And below is an image from the Polar Beats app showing what the Polar H10 Chest Strap recorded for the same exercise.
So maybe the Samsung watch is now sorted out with the firmware update. Only a few more exercises will tell. What I’m sure of now is it is not a hardware issue: Firstly, because the hardware was already replaced, and secondly because hardware does not usually just come right overnight. But Samsung seriously needs to give more attention to acknowledging when there are suspected bugs (and not telling every user they are the only person with that problem). In the last week I’ve seen a lot more search results showing up from the last few months about “inaccuracies with heart rate tracking during workouts”. I was clearly not the only one, but I had to battle this on my own, along with the local Samsung repair shop.
So, what if I wanted to use only the Polar H10 Chest Strap to exercise and did not want to keep looking at my phone to see the instant reading? Well, it turns out the H10 Chest Strap can handle two Bluetooth channels simultaneously, and it can even work in offline mode if the exercise has been started (you can leave your phone behind).
I found an app for the Android Wear OS watch called Sporty Go! See https://www.qooapps.com/sporty-go.html. The app opens and can connect to a Bluetooth heart rate tracker. You can either just monitor the live reading (as my image below shows) or you can get it to create and monitor an exercise type, and then send the data to Strava, TrainingPeaks, or Final Surge. It’s a whole exercise manager on its own. But in my case I’d probably manage the exercise from the Polar Beats app, and just use this on the Watch to glance and see my heart rate if I wanted to keep the phone in my pocket. The image below is taken whilst the Samsung Galaxy Watch was still running its exercise for the watch heart rate, and the Polar Beats app was also connected to the chest strap (to test two devices connecting to the chest strap at the same time). The app costs about $3 once-off for the Bluetooth connector, but you do get to test it free for 60 minutes.
And there lies the rub! On Android there is just no one single app that syncs everything, so some thought is required, and sometimes some creative thinking to chain things together. There is a new sync feature called Health Connect, that is available for apps that share to it, and read from it, such as Google Fit, Fitbit, Samsung Health, etc. This does make it possible for some sharing to happen.
But otherwise, this is what I see:
Samsung Health -> Health Connect, MapMyFitness (linked from MapMyFitness), Strava, Technogym.
Polar Beat -> Strava, TrainingPeaks, MyFitnessPal, Nike+, Discovery Vitality (my medical insurer), and Komoot.
Fitbit -> Health Connect, Strava, Datapult, Sync Solver (iOS), myFitnessSync, Zenobase, Data Sense, MapMyFitness, Endomondo, Runkeeper, IFTTT, Fluxstream
Google Fit -> Health Connect, MapMyFitness, Polar Beat, Strava, Welltory.
Strava -> Fitbit, Google Fit. Strava allows activities from Wear OS (Google Fit), Garmin, Samsung Health, ZEPP, ZWIFT, Wahoo, Polar, MIRROR, trim, and Suunto.
Oura Ring -> Health Connect, Google Fit, Strava.
Sporty Go! -> Strava, TrainingPeaks, or Final Surge.
So, it is a bit of a mix-match as to what connects to what and goes where. From the above though I do see Strava emerging as a common denominator for gather data, and then being able to social share with friends. It is also cross-platform so can survive any changes you make to devices or OS.
In the end I have no definitive solution for the issue of the heart rate tracking during exercises for the Samsung watch, except to say that you do need to follow the advice around fastening the strap a bit tighter, making sure you’ve run updates, try rebooting it, also try a factory reset without applying updates, etc. I’m more reassured thinking this was not a hardware issue.
But also, I’m really happy with the Polar H10 Chest Strap that complements the Galaxy Watch. I never had an issue with the Apple Watch ever doing this and it also did a pretty good HRV reading. Still the Galaxy Watch is one of the best Wear OS watches right now and I do get a good 2 days use on a charge, and I love all its other features (see https://gadgeteer.co.za/why-i-migrated-from-an-apple-watch-to-a-samsung-galaxy-watch-5/ for how I maxed out the battery life). The Quantified Scientist on YouTube is also using a Polar H10 Chest Strap as a benchmark for all his health tracking device tests. If one just wants good exercise tracking, then the chest strap would be good enough on its own. For example, the Polar Beats app has a free upgrade function that does a fitness test by just lying down for 5 minutes to take the measurement (as per image below).
But as this is an editable blog post, I’ll update this post with any further breakthroughs that I make with connecting my health trackers. I just wish now that the Samsung Health app would manage getting the heart rate data through that connected Bluetooth accessory that is registered and linked.

Né en 1910, Jean Amila est souvent considéré comme le vétéran du roman noir français. Mais ce qualificatif ne doit pas faire oublier que ses livres n'ont rien perdu de leur intérêt.

#POLAR #STRATOSPHERIC #CLOUDS: Arctic skies are filling with color today--but it's not the aurora borealis. A rare outbreak of polar stratospheric clouds (PSCs) is underway. Jónína Óskarsdóttir photographed the display from Fáskrúðsfjörður, #Iceland:
"We have been seeing these clouds for a couple of days," reports Óskarsdóttir. "In this picture, Mt. Jökultindur is silhouetted by a sky-full of nacreous color."

Lyon, sa police, ses bizarres héros, ses assassins, ses espions et les désirs d’une démocratie vivante forment la trame de ce roman. Gwenaël Bulteau raconte plusieurs histoires qui trouvent leur origine dans la guerre de 1870, La Commune – celle de Lyon a eu une existence encore plus éphémère que celle de Paris – et dans l’affaire Dreyfus qui secoue la France. Cette année là, Zola publie dans l’Aurore « J’accuse » qui provoque des émeutes. La police, comme l’armée est anti dreyfusarde dans sa grande majorité. « La République des faibles » est un titre volontairement ambigu. Il peut faire référence à la faiblesse de cette République aux mains de la hiérarchie militaire antisémite, des faibles laissés à l’abandon qui ne participent pas à la vie publique et aux faiblesses générales de cette société incapable de se comprendre.

Julian Semenov (1931-1993) est un écrivain célèbre en URSS. Sans doute moins dans la Fédération de Russie en raison des réécritures de l’histoire poutiniennes. Il fait œuvre à la fois de romancier et d’historien. « La taupe rouge » a été le premier édité. « Des diamants pour le prolétariat », qui se déroule en 1921 – l’URSS est toute neuve -, semble être le premier opus d’une série qui couvrira toute l’histoire de cette formation politique et sociale via l’espionnage. En avril 1921, la Tchéka charge un jeune agent, Maxime Issaïev – héros récurrent – de récupérer des diamants des possédants pour financer la jeune République des Soviets. Il infiltre le milieu des trafiquants, croise des tueurs, des voleurs tout autant que les révolutionnaires.
