By Daniel Puchert Partially state-owned telecommunications company Telkom announced in its financial results for the year ending 31 March 2025 that its ADSL subscribers had more than halved to under 30,000. According to the company’s operational data, ADSL lines decreased from 64,959 in March 2024 to 29,770. This 54.2% decline highlights that the legacy broadband technology is slowly approaching the end of the road. Telkom’s ADSL business peaked at the end of March 2016 with 1.01 million subscribers — two years after fibre upstart Vumatel broke ground in Parkhurst . What followed was a sharp decline in Telkom ADSL subscribers. Customers connected to its copper networks decreased by more than 500,000 over the next four years. This was partly driven by Telkom itself, which began actively switching off its copper network in some neighbourhoods. If it did not have fibre in the area, it would offer a “fixed line lookalike” wireless service that ran over its cellular ...

SpaceX hopes to launch, land new prototype of its Starship mega-rocket this week. The last 3 exploded
Starship launches have become a regular occurrence at SpaceX's rocket-development facilities in Boca Chica, Texas. For the second time this month, the company is preparing to fly an advanced prototype of its next spaceship.
Called Starship serial No. 11, or SN11, the prototype could launch as early as Tuesday. It's set to roar tens of thousands of feet into the air, shut off its engines, flip sideways, then freefall back to Earth. Four wing flaps should control the rocket's fall, and its engines should re-fire just in time to flip it upright and lower it to the landing pad.
SpaceX has launched three such high-altitude test flights already, but each ended with a catastrophic explosion. The first two prototypes, SN8 and SN9, slammed into the landing pad at high speed and exploded immediately. The third, SN10, landed in one piece but blew up 10 minutes later.
All these prototypes represent the upper stage of a two-part system: Eventually, a roughly 23-story booster called Super Heavy would heave the Starship spaceship toward orbit. The whole system is meant to be fully and rapidly reusable, which could enable SpaceX to slash the cost of reaching space 1,000-fold.
SpaceX founder Elon Musk's long-term vision is for the system to fly astronauts to the moon and power hypersonic travel on Earth. He has said he plans to build 1,000 Starships in order to carry people and cargo to Mars and establish a Martian settlement.
Spectators gather to watch SpaceX roll out the SN11 prototype.
SpaceX may try to fly and land SN11 as early as this week. The Federal Aviation Administration has issued airspace closures in the area for Tuesday, Wednesday, and Thursday, and the Cameron County judge has issued local road-closure notices for Wednesday and Thursday. Both air and road closures are required for launch.
However, these closures can be rescheduled if SpaceX is not ready to fly. Ahead of the SN9 flight, new closures were posted week after week before SpaceX made any launch attempt. We will update this post once SpaceX confirms a launch date for SN11.
Watch the Starship prototype fly live

SpaceX is expected to broadcast the test flight live, as it did with the last three. That livestream will be embedded below once it becomes available.
In the meantime, a few fans of the company are broadcasting preparation activities at the launch facilities. Some of their video feeds captured a static-fire test last week - that's when SpaceX fires a rocket's engines to test them ahead of flight.
LabPadre offers six unique views of the Starship launch site. Below is the channel's main 4K-resolution feed.
For a more distant view of the launch site - broadcast from the top of a resort in South Padre Island about 6 miles away - check out SPadre's 24-hour live feed.
NASASpaceflight also covers events at Boca Chica, offering broadcasts with multiple high-quality camera views and input from commentators. Their livestream of the launch will added once it's available as well.

By Andrew Aloia BBC Sport Last updated on 11 October 2021 11 October 2021 . From the section Football Watson was a trailblazer who helped transform how football was played There are two murals of black footballers facing one another across an alleyway in Glasgow. One helped shape football as we know it, the other is Pele. Andrew Watson captained Scotland to a 6-1 win over England on his debut in 1881. He was a pioneer, the world's first black international, but for more than a century the significance of his achievements went unrecognised. Research conducted over the past three decades has left us with some biographical details: a man descended of slaves and of those who enslaved them, born in Guyana, raised to become an English gentleman and famed as one of Scottish football's first icons. And yet today, 100 years on from his death aged 64, Watson remains something of an enigma, the picture built around him a fractured one. His grainy, faded, sepia image evokes many differen...

While jurisdictions in Europe and North America have been phasing out coal use in power generation, it has been on the rise in Asia. China and India are scrambling to provide electricity to a growing population and relying on coal power plants to meet demands despite the environmental costs.
