Twitter may ban Cryptocurrency, ICO ads

Twitter may soon join Facebook and Google in cracking down on ads for cryptocurrency-related products. Sky sources have claimed the social network will institute worldwide ban against ads for initial coin offerings, cryptocurrency wallets and token sales within the next two weeks. It might also ban ads for cryptocurrency exchanges with "some limited exceptions," according to the apparent leak.

The company told Engadget it had no comment at the moment.

Google is Banning Cryptocurrency Ads in June

Google is cracking down on cryptocurrency-related advertising.

The company is updating its financial services-related ad policies to ban any advertising about cryptocurrency-related content, including initial coin offerings (ICOs), wallets, and trading advice, Google's director of sustainable ads, Scott Spencer, told CNBC.

That means that even companies with legitimate cryptocurrency offerings won't be allowed to serve ads through any of Google's ad products, which place advertising on its own sites as well as third-party websites.

This update will go into effect in June 2018, according to a company post.

A US City Banned Cryptocurrency Mining

The city of Plattsburgh, New York announced on Thursday that it is temporarily banning the commercial mining of cryptocurrency for 18 months. 
The official reasoning for the moratorium is to "protect and enhance the City's natural, historic, cultural and electrical resources." 
Plattsburgh residents have seen skyrocketing electrical bills — as much as $100 to $200 increases — as a result of commercial cryptomining operations that mine for cryptocurrencies like bitcoin, according to Plattsburgh Mayor Colin Read, who spoke with Motherboard. The city is taking action to protect its citizens from those rising electrical bills that the city of Plattsburgh says is caused by cryptomining operations.

US Navy Remains Committed to Railguns

Following a flurry of reports in December predicting the Navy's $500 million electromagnetic railgun experiment was dead on arrival, the chief of Naval Operations told lawmakers this week that the death of the program was greatly exaggerated.

"[We are] fully invested in railgun; we continue to test it," Adm. John Richardson told the House Appropriations subcommittee on defense during a Wednesday hearing on Navy and Marine Corps budget issues. "We've demonstrated it at lower firing rates and ... shorter ranges. Now we have to do the engineering to, sort of, crank it up and get it at the designated firing rates, at the 80- to 100-mile range."

Richardson was responding to a question from Rep. Tim Ryan, D-Ohio, who expressed concern about the proven capability of the Navy's railgun weapon, which has yet to leave its test site at Naval Surface Warfare Center Dahlgren Division, Virginia.

Stealth Saga #73

Sixth Generation Fighter:

The US Air Force is warning the 6th gen fighter must arrive much faster than the F-35 did or it will be irrelevant.

China has begun work on its 6th gen fighter.


Japan is sending out an RFI for information from US aerospace companies to help build the follow-on to the F-2 fighter the second week of March 2018.

The next gen Japanese fighter will be based off a Western design.


The Anglo-French Future Combat Air System may be a casualty of Brexit.


The Indians are requiring any winning bid for the new fighters India wants to have help developing India's 5th generation stealth fighter.


The Russians have disclosed they sent the Su-57 to Syria to test radar and EW systems.  The aircraft has not been cleared for combat.

The Russians are now claiming they have withdrawn the Su-57s.

Israel is very concerned about the Su-57s in Syria.

A report claimed the Russians will be designing a new aircraft for use on its current (and possible future) carriers rather than use the Su-57.  However, the UAC came out and stated they are ready to make the Su-57 carrier compatible.


Is Tupolev struggling with being unable to find enough engineers and technically skilled people to build the PAK-DA?


The J-20 is not using the new engines (WS-15) designed by the Chinese.  The new engines are having problems during the development.  It seems to be related to metallurgy for the fan blades.

The J-20 was intended to be used as an air supremacy fighter, but will be developed into other variants like what was done with the F-15.


China's Shenyang Corporation has completed another J-31 prototype.  It should be noted the Chinese are calling the J-31 a research effort and not, as we americans call it, a program of record.  The J-31 designation is considered unofficial.


The prototype B-21 bomber(s) are being hinted at being unveiled because they need to be tested at Edwards AFB soon.

The B-21 is having some issues, but coming along well.  Supposedly.  The so-called Iron Bird is probably already flying based on reports from elsewhere.  This is how it gets transitioned into the White World.


The F-22 demo team changed pilots.

Watch an F-22 do an inverted somersault.

Listen to an F-22 pilot gas up his plane.

The F-22 pilot that reported the hypoxia problems may have been retaliated against.


The USMC is about to embark on the maiden operational deployment of the F-35B on the USS Wasp.

Watch the F-35Bs arrive on the USS Wasp.  The USS Wasp is headed to South Korea next month for exercises.

USMC Commandant is calling the F-35B key to the Marines.

The US Navy is getting frustrated it cannot connect the F-35 logistics software to its own.

Lockheed is being called 'uncooperative' on the F-35 contract.

Lockheed received an additional $148 million contract for more logistical support for the F-35.

Lockheed claims the F-35 will have really good readiness rates.

The Pentagon is doing a deep dive to figure out how to reduce the F-35's costs.

The F-35's costs are dropping, but not fast enough for the Pentagon.

The F-35 costs issues are fixable, but...

Half of F-35 manufacturing defects are stealth related.

Continued development and sustainment costs for the F-35 will be $1 billion annually.

US lawmakers quizzed the Pentagon over the F-35 costs.

The cost of the Block 4 software is increasing.

The Pentagon is seeking 400 GBU-49s for the F-35.

The US Navy gave Lockheed a $149 million contract mod.

One of the founders of Ben & Jerry's ice cream was arrested for protesting the deployment of F-35s to Vermont.

The head of the Luftwaffe, German air force, is losing his job (in large part) for advocating the F-35 for Germany.

The Indian Air Force denies it asked for a briefing on the F-35.  However, the head of the US Pacific Command has stated he'd like to see India buy the jet.

Israeli F-35As may have made their combat debut in Syria.  The Israelis won't confirm, but won't deny either.

The Italian F-35As have gone IOC.

An Italian party that has vowed to end Italy's participation in the F-35 may gain power.

The Japanese Defense Minister stated he was the one who authorized the study of placing F-35Bs on the Izumo.

Taiwan still hopes to buy F-35B.

Terma has joined the F-35 avionics test center.

Africa was Wetter During the Medieval Warm Period


Lüning et al


The Medieval Climate Anomaly (MCA) is a recognized period of distinct pre-industrial climate change, with a core period of 1000–1200 CE. The field of palaeoclimatology has made major progress over the past 15 years during which a great number of high- and medium-resolution case studies were published, reconstructing climate change of the past millennia. In many parts of the world, regional data coverage has now reached a point which allows compiling palaeoclimate maps for well-defined time intervals. Here we present hydroclimatic trend maps for the MCA in Africa based on 99 published study locations. Key hydroclimatic proxy curves are visualized and compared in a series of 16 correlation panels. Proxy types are described and possible issues discussed. Based on the combined MCA dataset, temporal and spatial trends are interpreted and mapped out. Three areas have been identified in Africa in which rainfall seems to have increased during the MCA, namely Tunisia, western Sahel and the majority of southern Africa. At the same time, a reduction in precipitation occurred in the rest of Africa, comprising of NW and NE Africa, West Africa, Eastern Africa and the Winter Rainfall Zone of South Africa. MCA hydroclimate change in Africa appears to have been associated with characteristic phases of ocean cycles, as also supported by modern climate observations. Aridity in Morocco typically coincides with the positive phase of the North Atlantic Oscillation (NAO), whilst increased rainfall in the western Sahel is often coupled to the positive phase of the Atlantic Multidecadal Oscillation (AMO). Reduction in rainfall in the region Gulf of Aden/southern Red Sea to Eastern Africa could be linked to a negative Indian Ocean Dipole (IOD) or a derived long-term equivalent Indian Ocean cycle parameter. The Intertropical Convergence Zone (ITCZ) appears to have been shifted pole-wards during the MCA, for both the January and July positions. MCA hydroclimate mapping revealed major data gaps in the Sahara, South Sudan, Somalia, Central African Republic, Democratic Republic of Congo, Angola, northern Mozambique, Zambia and Zimbabwe. Special efforts are needed to fill these gaps, e.g. through a dedicated structured research program in which new multiproxy datasets are created, based on the learnings from previous African MCA studies.
