This message is for Hospital trusts #NHSTrusts #GPs There are many thousands of people who are vulnerable and in a very difficult situation with #COVID that need safe access to medical care for some of the following reasons:
1. They are immunocompromised and have an allergy so can’t be vaccinated
2. UKHSA isn’t offering all cev vaccines who are still high risk. They are continuing to narrow the criteria and are leaving many with lung/heart/kidney conditions out in the cold.
3. Children who shielded
are now not all being vaccinated. These children were indoors for 20 months and many are understandably anxious at now not having vaccine protection.

Mais le niveau de la mer, c'était censé être la référence, donc 0m ?
Alors pourquoi un #GPS, placé à ~1m au-dessus de la mer, mesure 4m ?

#mer #mesure
1ᵉʳ indice : la #précision de base de mesure du système #GPS est vers ± 2,5m

⚠️ : La #gravité variant (de peu) selon le lieu, les récepteurs couplent la carte des géodésiques de mesure au "Earth Gravity Model 1996", améliorant la précision vers ±0,5m
fr.wikipedia.org/wiki/Global_Po…
2ᵉ indice : Le "niveau de la mer" moyen n'est pas LE niveau de la mer
Il y a des vagues, ok, mais pas que, le niveau de la mer varie globalement et localement selon :
- La gravité (encore)
- Sa température
- La pression atmosphérique
- La lune (marées)

اجازه بدید امروز به سبک ما الکترونیکی ها یه سفر مجازی تکنولوژیک بریم، مواد لازم:
یک عدد hackrf اجباری
تقویت کننده سیگنالGPS اختیاری
گین کنترل اختیاری
آنتن ایندور باند GPS اجباری
به مقدار لازم هم کابل و اتصالات RF
#gps #gps_spoofing #gps_jamming #RF
بعد از تهیه مواد لازم /۱ Image
مثل عکس قبل به هم وصل می‌کنیم و دیگه کار سخت افزاری دیگه ای نداریم و باقی فراینده ها نرم افزاری است، من از لینوکس استفاده میکنم و ابزارهایی که کانفیگ میکنم برای لینوکیه،‌اول پک مورد نیاز برای hackrf رو با دستور زیر نصب کنید /۲
#hachrf Image
حالا نیازه که GPS-SDR-SIM رو کامپایل کنیم اول اونو از آدرس زیر کلون کنید، بعد طبق توضیحات خودش هم میتونید برای ویندوز و هم لینوکس کامپایل کنید/۳

@XsukysukyX @Ghostof_Atticus My father was a branch chief at NRL who retired in 1980. As far as I can tell, Dr West’s work on the GEOID was in the 1980s. Dad didn’t work on the GEOID so how he could make a mathematical error there escapes me. I doubt if he ever heard of Dr. West. 1/
@XsukysukyX @Ghostof_Atticus Dad designed the 1st satellite with solar cells which power #GPOS satellites. He designed 2 space tracking systems (Minitrack and the Naval Space Surveillance System System). Space tracking is key to predicting future positions of GPS satellites. In 1964, he started working on 2/
@XsukysukyX @Ghostof_Atticus on a Navsat using atomic clocks which again is a key feature of GPS. His Timation Dev Plan (1971) has all the major features of GPS (sat configuration, ground station positions and signal structure). gpsdeclassified.com/wp-content/upl… 3/

¿PUEDE LA POLICÍA ACCEDER SIN AUTORIZACIÓN JUDICIAL AL CONTENIDO DEL GPS INSTALADO EN EL VEHÍCULO ALQUILADO Y CONDUCIDO POR EL ACUSADO?

Se pronuncia sobre esta cuestión la STS 835/2022, de 21 de octubre (ponente Susana Polo)👇
En este caso el acusado fue condenado x la AP x un delito d tráfico de drogas a la pena d 6 años y 7 meses de prisión, fundamentándose la st, entre otras pruebas, en la información obtenida por la Policía del dispositivo GPS instalado en la furgoneta q había alquilado el acusado.
Contra dicha st se interpuso recurso de apelación ante el TSJ, quien desestimó el mismo. Y frente a esta st recurso de casación, alegando la nulidad de la información obtenida del GPS sin autorización judicial por vulnerar el artículo 18.3 CE (secreto de las comunicaciones)

@realhomerhickam In January 1958, my father realized that Soviet spy satellites would be quiet most of the time and a new tracking system was needed. He devised the Naval Space Surveillance System. When the Project Vanguard people transferred to #NASA, he was one of the few people who stayed 1/
@realhomerhickam at @USNRL. In 1964, the need to synchronize clocks in different space surveillance stations was an inspiration for him to start his Timation Navsat which led to #GPS. The space race resulted in many things besides Apollo 11. You can see a representation of space surveillance 2/

The issue with #NP problems is Uncertainty. The greater amount of information about the problem, the less Uncertainty & therefore, the less Computational Complexity. In case of no Uncertainty, NP=P. #NPplusInformationEqualsP @ulisescortes @sierra_carles @vdignum @wooldridgemike
In practice, that's what #DeepLearning does: it gathers data of the problem but runtime is P.
In Research too: we publish about problems until we find a P solution and then we continue optimising the solution in case we need a trade-off PSPACE/PTIME. #AI #MachineLearning
Could we create a Problem Information System to reduce the complexity of Research in general?Could it be automated to the greatest extent? That would be a General Problem Solver. We can be greedy & blindly publish in words everything we might solve, or we could start making a PIS

After 6 years and billions of transaction, @NPCI_NPCI talks about 'consent' while collecting geo-coords for every #UPI txn & gives 6 more months time to make such data collection a choice based consent.

Is there a #GPS coord in India - where @NPCI_NPCI doesn't have txn data
#CashlessConsumer had noted about this geo-coord collection for every txn as a key surveillance concern back in 2017 - medium.com/cashlessconsum…
In the light of recent #CrPC91 request - it is valuable to revisit the privacy guarentees in the payment systems and #PaymentsPrivacy is key to having civil liberties and is no longer a niche digital rights problem.

Lieber Herr @MarcoBuschmann,

das nächste Mal, wenn Sie oder die @fdpbt eine längere Laufzeiten von #AKW oder gar den Neubau fordern, bestehen Sie bitte auf den Nachweis der Kernspaltung als auch der Einsteinschen Formel E=m*c^2. 1/
Ohne diese Evidenz wird ggf. kein AKW jemals rechtssicher Strom produzieren. Rechtssicherheit geht ganz klar vor Nutzung des Atoms. 2/

This arrow points to the Singapore the Wall Street of Asia, the entrance to the South China Sea and the most important maritime “choke point” in the word. In black letters is the Chinese Navy’s #PLAN new base. washingtonpost.com/national-secur…
A choke point is an area where traffic meets and a numerically inferior defending force can use as a force multiplier to thwart or ambush a much larger opponent or cripple the economy of large regions of the world.
This news is also important because Cambodia is chair of the 10-member regional Association of Southeast Asian Nations (ASEAN) this year, Cambodia is keen to avoid the perception it is “a pawn” of Beijing.

It confirms the concerns of the children⬇️

"We feel ignored"

April 1st - 12 #children living with #LongCovid traveled
to #london to deliver their own letters documenting their #pain, loss of #sight, #mobility, organ damage, diagnosis of #PANS #MECFS #FND #POTS #MCAS and the detrimental impact it has had on their lives.

#LongCovidKids
100+ page guide providing evidence-based information on #LongCovid in CYP from industry experts, research, and statistics from @GOVUK @ONS.
Did anyone read it?

Both of these charismatic species exhibit what scientists call “natal philopatry,” which means they return to their birthplaces to breed!

Adélies often end up building their pebble nests very close to where they hatched. #takeoverNSF
