[THREAD] 🇳🇴 Spécialiste des technologies sans fil Nordic Semiconductor a été l'une des entreprises les plus performantes du secteur sur les 10 dernières années. Quelles sont ses activités ? ses atouts ? peut elle devenir une blue chip du secteur ? 
➡️ Analyse : Présentation / Activités / Valorisation / Perspectives / Forces et faiblesses / Conclusion 👇
[1/4][Présentation] Nordic est une société Norvégienne fondée en 1983 et spécialiste des technologies sans fil basse consommation sur courte distance. Comme de nombreux acteurs du secteur la société est dite fabless (elle ne fabrique pas elle même les puces qu'elle conçoit)

#CaptainFuture (alias Michael Bründel, Verschwörungsanhänger) läuft auf einem Friedhof herum und sucht #Bluetooth-Signale von geimpften Verstorbenen.
Später erklärt ihm ein Angestellter, dass dort nur eingeäschert wird.
Wow!
Der Mikrochip übersteht sogar die Einäscherung. :D

In einem anderen Teil des Videos glaubt Verschwörungsanhänger Michael Bründel (Teil der #FreedomParade) die Bluetooth-Adressen der Verstorbenen würden "wechseln".
So lost.

Verschwörungsanhängerin #KarolineSeibt ("Anwältin für Medizinrecht") hatte sich bereits im März 2022 damit befasst, konnte es allerdings nicht testen, sie in ihrem Umfeld "keine geimpften Personen" habe.

Enfin ! L'étude d'impact de #TousAntiCovid, que le gouvernement devait fournir avant fin janvier... 2021 (!), a été publiée par la Direction générale de la Santé. Au vu de ses résultats, la question se pose : faut-il arrêter @TousAntiCovid ? @LaTribune latribune.fr/technos-medias…
Le rapport #TousAntiCovid qualifie le contact tracing de "marginal" dans la lutte contre le #COVID19, au mieux "complémentaire" du contact tracing humain, et vraiment utile seulement en pic de crise Omicron. Les biais et limites de cette étude d'impact (page 29) sont sidérants 👇
L'utilisation et l'appréciation de l'app #TousAntiCovid se base sur une étude de Kantar jugée "non-représentative" (!). Autre aberration : pas de données sur l'utilisation du #Bluetooth ni sur le nombre d'utilisateurs actifs par jour pourtant crucial pour en comprendre l'utilité
Ce thread pour vous rappeler que l'équipe propose une compilation de tests de manette #Nintendo #Switch. Celui-ci s'enrichit de jour en jour selon les manettes que l'on arrive à dégoter. Evidemment pour le moment celle qui tient le haut du podium ... air-gaming.com/le-comparatif-…
est la manette #NintendoSwitch Pro qui propose en plus d'une ergonomie au top le #bluetooth natif et fonctionnel (voir l'article pour rigoler sur certaines manettes). En deuxième on placera la pas trop mal @horiusainc HoriPad, qui reste filaire. Puis...
pour les moins exigent en nombre de boutons et stick analogique la @8BitDo_FR m30 (ready pour essayer SN30PRO V2). Pour le reste, on est toujours à la recherche d'une perle rare. On va tenter la @NyxiGaming (coucou les gars, n'hésitez pas à nous MP), la @ChereekiCN , la @QUMOX...

1⃣ Es posible que os baile la cronología vikinga. Tradicionalmente se usan como inicio y final del periodo dos fechas:
793-Saqueo del monasterio de Lindisfarne (Inglaterra)
1066-Derrota de Harold el Despiadado en la batalla de Stamford
Por tanto, se ubican entre los s.VIII y XI

2⃣ No constituyeron un estado unificado, sino que les unían la lengua (noruego antiguo), la cultura y las creencias religiosas. Suele hablarse de #vikingos daneses, suecos y noruegos, según su ubicación original.

Y es verdad que fue actriz de Hollywood en la década de los 40, pero es que estamos hablando de que esta mujer diseñó un sistema de comunicación para guiar torpedos en la guerra, que con el tiempo derivó en el wifi y otras tecnologías de comunicación sin cables. WTF!
Sin embargo, Wikipedia, por ejemplo, solo destaca de ella en la captura de su perfil su faceta como actriz. Buscando en Google encontramos un sinfín de titulares sexistas y totalmente injustos como estos. Con un hombre lo hubieran hecho también, ¿verdad?

...and, as the BBC's write-up concludes, evidence that #ExposureNotification works in practice is "scant" - in ALL countries attempting it, not just the UK:

Efficacy (as in NZ) will most likely come from #QRcheckin, which could've been done months ago.

Bottom line, will I be downloading it? Already have - as I did with the other versions, to see what they did.
Will I be using it? Probably. Not least to avoid having to hand over personal details; combined with regular data deletes/resets.
Will I trust it to keep me safe? No...

1/30 In two forthcoming pieces, I examine #Japan's response to the #COVID19 #coronavirus #pandemic. I'll summarize the main non-theoretical points here (long thread alert!).
2/30 #Japan’s figures have always looked good compared to many other countries, which initially led to suspicion that the ‘real’ numbers of #COVID19 #coronavirus infections & death were being played down.
3/30 #Tokyo Metropolitan Government at least has now released full #COVID19 figures, including general death rates, seeming to put this argument to rest (but these figures are also now being challenged). japantimes.co.jp/news/2020/05/0…

1. mi sento ancora una volta in dovere di aiutarvi a capire la questione fondamentale della #sorveglianzaDigitale contro il #COVID, non solo perché sono temi che conosco in modo profondo,ma perché ho preso coscienza della questione #DatiSanitari per una vicenda personale
2. rispetto #FiorenzaSarzanini,ma con tutto il rispetto NON è possibile pensare di imbarcarsi in un programma di #sorveglianza di 60MILIONI di italiani premettendo "vedremo se funzionerà", poi "se qualcuno avrà sbagliato, pagherà". Qui sono in gioco questioni cruciali
3. voglio premettere che,personalmente, NON sono una fanatica della #privacy:come giornalista,ne ho una profonda conoscenza e coscienza,perché ho il dovere professionale ed etico di proteggere le persone che parlano con me: le mie fonti
1. ancora una volta, io sento il dovere di NON stare zitta e dire quello che in una fase di grande "distrazione" (come nooo...) non viene detto sulla "APP" (#sorveglianzaDiMassa) contro #COVID, perché gli sviluppi che vedo sono a dir poco preoccupanti
2. dopo una fase in cui abbiamo temuto il peggio del peggio, ovvero una #sorveglianzaMassa stile #CoreaDelSud con integrazione #datiLocalizzazione,#DatiSanitari,#CarteCredito,#videocamereTelefonini e di tutto di più,ora ci viene proposta una soluzione apparentemente più decente
3. ci viene lasciato intendere che abbiamo scampato il pericolo del modello #CoreaDelSud e che non verrà usata la #geolicalizzazione spinta nelle intenzioni originali di #VittorioColao, ma verrà usato il #bluetooth
Because several people were asking about #Bluetooth, I'll make a thread. But I might ignore further questions, especially regarding over-the-air exploits. #DP3T

• BLE advertisements have a longer range than 2m, but are way more accurate than LTE cell towers.

• BLE advertisement distance measurement accuracy depends a lot on the chips, meaning that they will work well within the Apple ecosystem, but probably not so well on some Androids. (2/n)
• The Singapore app solves this by maintaining active BLE/GATT connections, which provides better measurements, but drains battery power.
• On iOS, the BLE/GATT handler has been extensively tested for security issues and is definitely one of the better ones by now. (3/n)

Q: What is contact tracing? Why is it so important?
A: Contact tracing limits exposure to #COVIDー19 by
🔎identifying people who have been in close contact with an infected person,
📲encouraging them to self-isolate, and
📊following up to monitor their symptoms.
