NASA's Space Launch System rocket is on track for August 29 liftoff


Re: robotic missions

Yes, but you're assuming one Discovery-class mission per launch. The largest Discovery mission so far is Lucy at 1,550 kg, because they are launched with Atlas V or Delta II rockets. Psyche is in development to be launched with the Falcon Heavy and will have a mass of 2,608 kg. The first and smallest payload configuration for SLS is 70,000 kg. It could potentially launch dozens of Discovery-class missions simultaneously. Sort of like comparing a semi truck to a mini.

GitHub courts controversy by suspending Tornado Cash developers and reneging on cookie commitments


Is it protected speech?

"publishing the code on its own is protected speech"

Radio jammers are illegal in the US, as they could be used to block GPS or emergency calls, yet publishing plans for making one is protected speech. On the other hand, as of August 24 the BATF rules will make publishing a 3D printer model file for making the receiver of a firearm illegal. So you see, until challenged in court, the interpretation of the law is left to the whims of bureaucrats at alphabet soup agencies. It is still too early to know whether or not the affected code is protected speech or not.

British intelligence recycles old argument for thwarting strong encryption: Think of the children!


Reads like a paper proposing a perpetual motion machine

It is clear that there can be no compromise. Data is either encrypted or it is not. No matter in what way the encryption algorithm is borked, criminal hackers will eventually find the bork. Borked encryption is exactly equivalent to no encryption at all. Actually, it is worse, a false sense of security. It is also clear that most online services are not viable without encryption. Basically, we either have unborked encryption or we pull the plug and stop using the internet. So like a perpetual motion proposal, their paper is entirely based on the false assumption that borked encryption is even possible. I wonder if that lot has written a paper about curing a headache by cutting off the head.

SCOTUS judges 'doxxed' after overturning Roe v Wade


LOL! Did you get this info from a B movie about Appalachia or something?

Never fear, the White House is here to tackle web trolls


Oh, they understand it. The problem is that it limits the power of those same politicians, and so they try to circumvent it in whatever way possible, or whatever way they think they can get away with.

UK Home Office signs order to extradite Julian Assange to US


Re: Appeal

Well, there's also the tiny matter of Manning having stated during her court martial, to which she (actually he back then) pleaded guilty, that Assange had agreed back in 2010 to help with cracking an administrative password on a military system, and subsequently did so.

Her sentence was commuted by President Obama in 2017 and she almost immediately became a candidate for the 2018 Senate race in Maryland, which she lost. She was jailed again for a year in 2019 for refusing to give testimony to a federal grand jury in Virginia regarding the Assange case. In 2021 she was hired by a Swiss cryptocurrency startup to conduct a security audit. Her book is slated to be published in 2022. You really can't make this stuff up!

Anyway, had he just agreed to go to trial in the US back then, he too would have been pardoned by Obama and be running for public office and publishing his own book by now. Think about it! He's essentially already been imprisoned longer that Manning, and she pleaded guilty.

Apple’s M2 chip isn’t a slam dunk, but it does point to the future


Not that odd. There is no external memory bus. It can only use whatever RAM can be crammed onto the die. It restricts the quantity of RAM, but also eliminates a much slower bus. All RAM is accessed at on-die speed.

Taser maker offers electric-shock drones to stop school shootings


Yes. It would turn it into a standing army, which is specifically banned in Article I.


There is already registration for certain classes of firearms, namely automatic firearms of any kind, including 3-shot burst / select-fire weapons, short-barreled shotguns, explosive ammunition, and basically all military firearms.

And of course bans do nothing. Criminals, by definition, don't heed laws. Licensing? Well, one is required to have a valid license to drive a car, yet it doesn't stop people who have had their license revoked from driving drunk and killing people. Not sure that would work. Again, only the people who weren't going to shoot anyone anyway would bother with the license. America already bans felons from buying guns, and it works. Gun stores don't sell to them. Felons buy guns from the same people they buy their drugs from. Btw, the drugs are banned too.

Appeals court unleashes Texas's anti-Big-Tech content-no-moderation law


Re: Republicans are the perps not the victims

Well that's a bit misleading, opinion of orange-hair notwithstanding. There was 435 miles of new wall built. It is only perhaps 50 miles longer than pre-Trump walls, but go have a look at the before and after. Nearly 400 miles of either wire fence or 3 ft tall vehicle barriers that one could walk through were replaced with 30 ft tall walls.

Btw, the caravans were people mostly from various South American countries, not Mexicans. They were a huge problem for the Mexican government as well.


Re: They should just stop doing business in TX and FL.

TX and FL? A mere 50 million people. Surely there is no business to be done with so few. It would be no worse than stopping business with some EU countries....

RISC-V CEO seeks 'world domination' by winning over the likes of Intel


Re: re: Redmond tells us they are looking at RISC-V to diversify their risk.

I don't think Microsoft will lose market share to RISC-V, at least not anytime soon. My guess is that ARM will lose market share to RISC-V in the microcontroller market for web cams, refrigerators, smart light bulbs, and smart whatevers. These controllers don't have the software compatibility issues that a PC/laptop has, since they are fixed, single-purpose devices.

US Space Force unit to monitor region beyond Earth's geosynchronous orbit


Re: For those

Actually, the US Space Force more or less uses the Air Force ranks, except the lower level non-com ranks are Specialist 1,2, and 3, rather than Airman 1,2, and 3. For commissioned officers, Space Force is the same as Air Force through the rank of Captain. But it has only 3 field grade ranks as opposed to the Air Force's 5, so the roles assigned to field grade officers differ from their Air Force counterparts. Not sure about general officers.


Re: For those wondering "Why?"

That is also a good overview of why a Space Force would be beneficial. Each of these branches also share some common space-related needs, for example emergency satellite launch capability, LEO object tracking, (and perhaps even the new high orbit tracking) etc. It's just an organizational move to eliminate the unneeded overlap. The space-related needs of the branches are much more similar than their air support needs.

National Security Agency employee indicted for 'leaking top secret info'


Re: "The NSA is [..] supposed to be very good at securing data"

In all fairness, betrayal of an insider who already has access is a most difficult thing to prevent. No doubt company 2 paid even better than company 1. Of course, this is far from over, and the NSA is no doubt after RF and both companies and probably some of RF's colleagues. He was the first before a court and so it became public knowledge.

The wild world of non-C operating systems


Re: What about Assembly Language?

You do realize that every OS has bits written in assembler, yes? For example, the entire arch directory of the Linux source tree. This is because there are ISA features, particularly supervisor-mode instructions, for which the high-level language has no matching construct. There are still many hardware features that aren't implemented in the language, but are rather handled by intrinsic functions, for example SIMD instructions. So, actually it is still ESSENTIAL to know, at least for those not working exclusively with user-mode code.

Hear us out: Smartphone lidar can test blood, milk


Re: Too good to true?

My experience is with using LIDAR with modulated visible range lasers to evaluate heat damage in composite materials used in aircraft. I'm an engineer and worded on the data acquisition and coding, not one of the scientists, but I can tell you that special sensors, either PMTs or "silicon PMTs", which are arrays of avalanche photodiodes, were needed to measure the tiny signal gathered from the back-scattered light. These have a gain of between 10^6 - 10^8, whereas the gain on the photodiodes used in a phone's CMOS sensor(s) have a gain of between 10*2 and 10^3. The analytical chemist said that the SNR would be far too small if photodiodes were used. Just saying.

Where are the (serious) Russian cyberattacks?


Re: Or

A terrible job market means that one might have to find another line of work. It is not a reason for choosing to be a criminal. Breaking in and encrypting someone's data and demanding ransom IS stealing from others BY FORCE. They don't kill anyone, but otherwise how different is it from what the Russian government is doing in Ukraine? Russia is run by gangs of thugs, and most of them work for one of those gangs. It is not a stretch to assume that they would also work for Putin. It's all about money, and they don't seem to care where it comes from, which is why they became criminals in the first place.

Into x86 servers? Apple seeks 'upbeat and hard-working' hardware engineer


Re: Well, that's for the previous El Reg article dreaming about a Google's M1-like cloud...

There's nothing to test. The M1 has no external memory bus or chip-to-chip QPI bus, so cannot work in a multiprocessor server and is unable to access more than 64 GB of RAM. By contrast, a dual-processor C621 motherboard can have 4 TB of RAM and 76 Xeon Scalable cores and can handle hundreds of EC2 instances.

Re: It's A Bat-Signal !

That's not fair. His rocket's second stage is only crashing into the Moon by chance. In another such launch the second stage may well miss the Moon and be drawn into lunar orbit, in which case it would periodically beyond the Moon. There's even a small chance that an out of control, tumbling second stage could be slingshot by the Moons gravity and exceed Earth's escape velocity.

IPv6 is built to be better, but that's not the route to success


Re: Won't happen in my lifetime

I think you're right, other than the easily remembered IP address bit. Increasing the address space to 128-bit is going to make it hard to remember regardless of format.

They just simply made too many changes and made it cumbersome. Maybe an IPv5 that just increased the address space would have worked better?

Japan solves 5G airliner conundrum: Keep mobe masts 200m from airport approach paths. That's it


Wait a sec....

If the US aircraft industry is seriously concerned, then has anyone considered that all a terrorist has to do is setup a C-band transmitter anywhere near an airport to cause all sorts of chaos? Wouldn't it be safer if the RADAR altimeters were a bit more resistant to interference than that? This sounds more like a bureaucratic issue, rather than an actual safety issue.

Secure boot for UK electric car chargers isn't mandatory until 2023 – but why the delay?


Re: Secure boot is going where?

The difference is that the petrol cannot carry a virus into your car's system. In addition to charging, the charger also communicates with the car through the cable, so could potentially allow attacking the car via hacking the charger.

ESA's Solar Orbiter sails safely past Earth despite orbiting debris concerns


Re: 10,000ths of a radian per second

The force needed to accelerate something at 1G is dependent on something's mass. The Solar Orbiter's mass is 1,800 kg, so acceleration at 1G would require close to 18,000 N, not 100. Acceleration at .5N thrust would be less than 0.0003 m/s^2, so about 0.00003 G. It is a very tiny thrust.
