@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 -…
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/
Bitte vergessen Sie nicht, die Karlsruher Nuklidkarte validieren zu lassen. Andernfalls ist ggf. kein rechtssicherer Betrieb von AKW in Deutschland möglich. Es gilt weiterhin: Rechtssicherheit geht klar vor Nutzung des Atoms. 3/

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.…
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.

💈On the day the @ons report 26,000 CYP have symptoms for at least a year (⬆️ 3000 from last mth)
we received an email from @10DowningStreet in response to our visit on April 1st
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.

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

Drones, Fitbits and AI, oh my: Happy #WorldPenguinDay! Come learn about how #NSFfunded researchers from @PointBlueConSci study Adélie penguins at one of the windiest locations on Earth. #takeoverNSF

Can you guess what an Adélie penguin 🐧 and a salmon 🐟 have in common? #WorldPenguinDay

📷Matthias Breiter

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

On compare souvent la taille du miroir de @ESA_Webb avec celle de @NASAHubble, mais la taille ne fait pas tout. L'orbite de #JWST autour de L2 dont je vous ai déjà parlé fait une énorme différence. Je vous explique pourquoi dans ce #thread
#Hubble (HST) se trouve en orbite basse, à environ 540km d'altitude. @NASAHubble fait le tour de la Terre en 1h30. Pour comparaison, l'@Space_Station se trouve à environ 420km et les satellites #GPS et #Galileo sont à plus de 20 000km d'altitude.
Cette orbite basse a été très pratique pour y effectuer des missions de maintenance sur le télescope. 5 missions de service ont été effectués par les astronautes de @NASA entre 1993 et 2009. Plus aucune mission de service n'est programmée à l'avenir.

Ce tweet a eu son petit succès, je crois qu'il est temps d'en dire un peu plus sur le pourquoi du comment
#lièvre @OFBiodiversite @OSURennes #FDC35
je me lance dans mon 1er #thread👇
cette semaine, c'était donc #captures de #lièvres d'Europe en Ille-et-Vilaine en collaboration avec la FDC 35, une FDC tjs très intéressée dès qu'il s'agit de travailler avec nous sur le lièvre
Comment on capture un lièvre ? soit en utilisant une cage-piège, soit à l'aide de filets et de beaucoup de bénévoles. pour des captures tôt en saison, avec une faible végétation => capture au filet

Happy first day of #BlackHistoryMonth! To celebrate, we'll periodically take time to honor the brilliant Black minds that have contributed to our field over the years. A thread: Image
First up in our series: @6Gems, who founded @BlackGirlsCode after noticing the severe underrepresentation of minorities in the startup world. Bryant's nonprofit has enabled many young black girls to create meaningful work & go on to become leaders in their communities. #BHM2022 Image
@6Gems @BlackGirlsCode Katherine Johnson was a human computer whose calculations were essential to @NASA's Project Mercury, Apollo 11, and more. When the space program switched to digital computers, Johnson helped confirm the accuracy of their calculations. Image

Direct Hit! NASA, NOAA & MetOffice predictions agree the #solarstorm launched Jan 29 will hit Earth by early Feb 2! This one is slow so expect #aurora only as far south as Netherlands, north USA, & up to north New Zealand & Tasmania. #GPS & HF #radio issues on Earth's nightside!
The earlier post showed NOAA/SWPC prediction. This one shows the NASA prediction, which indicated the #solarstorm could hit as early as 18:00 UTC on February 1.
The final post is the MetOffice/MOSWOC prediction. This model shows the #solarstorm hitting by 05:00 UTC February 2. So we have a range from 18:00 UTC on February 1 to 05:00 UTC Feb 2. If the #solarstorm hits early, it will be faster and stronger; if hits late, slower & weaker!

🔴Info @Valeurs. En juillet à Nantes, un mineur avait agressé un automobiliste avec une extrême violence, avant d'être interpellé. La police confirme qu'il s'agit du même mineur soupçonné davoir poignardé à mort un père de famille ce 10novembre, à Nantes⤵️…
Voici les photos de l'automobiliste agressé en juillet, à Nantes, dans un parking, à coups de démonte-pneu, alors qu'il venait de garer sa voiture. Tabassé, trainé au sol puis étranglé sur la banquette arrière, il avait pu s'échapper et prévenir la police 👮‍♂️ nantaise ⤵️
➡️ Selon le PV de plainte que @Valeurs a pu consulter, l'un des deux agresseurs aurait dit à l'automobiliste après l'avoir tabassé dans le parking (son crâne conserve l'emprunte de la bar de fer): « Là où on t’emmène, t’es mort. Tu n’aurais pas dû te débattre, tu vas mourir »

Wenn wir euch in unseren Reihen "Apps gecheckt" und "Frisch getestet" Apps empfehlen oder vor ihnen warnen, geben wir auch den App-Anbietern Bescheid. Vor kurzem haben wir euch hier vor der #McDonalds-App gewarnt - und können jetzt Entwarnung geben. 1/6 @UlrichKelber @KastropC
Die #McDonalds-App hatte in unserem Test die eindeutige Router-Adresse (#BSSID) an Dritte weitergegeben. Mit der kann man hinter eurem Rücken euren Standort ermitteln. Anders als die zustimmungspflichtigen #GPS-Standorte sollte eure BSSID deshalb absolut niemand bekommen. 2/6
#McDonalds reagierte prompt. Man bedankte sich für unsere Meldung und leitete sie an die entsprechende Fachabteilung weiter. Die teilte uns dann letzte Woche mit, dass man unseren Hinweis sehr ernst genommen und umgehend geprüft habe. 3/6

It’s September - time for the annual run to raise/close out #VC funds before the end of the year. For many #GPs - this means reaching out to an LP who passed on a previous fund.
This thread deep dives into what to keep in mind as you circle back and reach out to #LPs that passed in the past (which I *do* recommend doing btw)👇

(Note: Drawing inspiration from this wonderful thread by @dunkhippo33 on a similar dynamic when entrepreneurs are turned down by #VCs:)
