Survey of astronomers and geophysicists shines a light on 'bleak' systemic bullying

Tessier-Ashpool

I would add that it's pointless debating the finer points of logic on CIF with social justice warriors, because you just get moderated. It doesn't matter if you present an irrefutable argument; if it doesn't fit the narrative it just gets wiped. I spent years getting zapped for pointing out the prejudice of having a women's section but no men's section, i.e. feminism not egalitarianism. My message finally got through after years of complaint.

Thankfully, El Reg generally steers clear of politics. I prefer it when articles stick to technical matters.

Mountains on neutron stars are not even a millimetre tall due to extreme gravity

Re: "extreme gravitational fields"

They are also insanely hot, with a surface temperature of more than half a million Kelvin. And some of these city-sized objects that weigh as much as a sun spin hundreds of times a second.

Re: Misnomer

The LIGO detector absolutely works on the principle that gravitational waves distort spacetime. The waves squeeze and stretch space, making their detection possible. The bent space is the path that the gravitational waves create.

Re: "extreme gravitational fields"

I think you’re a bit off there. Plugging in values for Gm1m2/r2 suggests an acceleration of around 10^12 m/s2.

v2 = 2as over 1m would suggest an impact speed of around 2000 km per second.

Apple scrambles to quash iOS app sideloading demands with 'think of the children' defense

Tessier-Ashpool

Re: Browser

For those with memories long enough, Jobs' first beef with Flash was that it killed the iPad's battery. Ergo, shit performance.

Tessier-Ashpool

Re: Browser

I can think of a couple of reasons: Security and Performance.

Adobe Flash was banned from iOS many years ago for exactly these reasons.

I imagine that WebKit has privileged access to, and control of, all manner of underlying networking libraries, for very good security reasons.

It's quite unlikely that third party browser engines could significantly increase performance, but it's very likely that they would decrease performance, potentially impacting the iGadget's other apps and processes.

WebKit is used internally throughout iOS itself and its stock apps. I imagine that third party browser front ends have access to those capabilities.

"According to Apple, 500 reviewers scrutinize 100,000 new and updated apps a week."

Ooh, I don't know. Perhaps there are just way too many apps on the App Store. There's a virtually uncountable number of crap apps.

Tim Cook: Sideloading is a disaster and proposed App Store reforms would harm user privacy and security

Re: Sideloading

Don’t forget that smartphone users are idiots who need protecting from themselves. That’s been Apple’s approach for many years. It’s only in recent times, for example, that the concept of a file has been exposed to iPhone users. Prior to the Files app, things were just things, like photos or emails.

BT sues supplier for £72m over exchange gear that allegedly caused wave of ADSL outages

I had one hell of an impedance mismatch problem when a storm blew down a massive tree opposite my house, which left broken phone lines trailing across the road. On my mobile to BT support, it was a little amusing to hear her say that they would run a line check.

It's not a good thing. The point is, a CDN is generally not a single point of failure, exactly the opposite in fact. But something has clearly gone terribly wrong in the management of the CDN.

How many remote controls do you really need? Answer: about a bowl-ful

Tessier-Ashpool

Re: Mother knows best

I have a metal Samsung remote that is excellent. Quite minimalist and very tactile. It also controls my Apple TV box attached to the TV, so it’s the only remote in the living room. I can’t fault it, really.

https://www.samparts.eu/en/samsung-bn59-01270a

The TV, on the other hand, is not so great. QLED 4K resolution is crisper than my eyes will ever need. But it’s kind of washed out, and I never get to see the inky blackness of my previous screen, a Pioneer Kuro. Also, I *never* want to see an advert icon on my TV’s menu, but there’s no way to turn this off.

Re: Safari and Internet Explorer

Your arguments are full of guff.

Adobe Flash was banned from iOS because its wonderful rendering engine killed off the battery. That's the kind of world you can look forward to with arbitrary browser engine installation.

There *are* Apple competitor apps on the App Store, for example numerous email clients, so the "nothing that competes with something we do" policy is all in your fevered mind.

WebKit is a core component shared by multiple apps on iOS.

If Apple allowed arbitrary browsers to have full control of the networking stack and rendering capabilities, you'd end up with browsers like full-fat Chrome on iOS that use decidedly privacy-hostile web standards. Apple can't permit that at the same time as advertising that they protect your privacy.

Tessier-Ashpool

Re: Safari and Internet Explorer

My gaff, my rules.

Apple do not license iOS to any other party, and also have direct control over the hardware on which it runs.

They also have to be very sure that any installed software doesn't compromise the security or performance of the platform. Can you imagine what would happen if Porky's Bloaty Browser were to be installed from the Mogadishu App Store? People would be turning up at Apple Stores demanding to know why their email stopped working.

Energy density and dodgy design. I imagine if all the squealers demanding user-replaceable batteries in phones had their way, it would only be a matter of time before cheap unsafe knock-off batteries became a big issue. Want to see your phone doing a fiery impression of Thunderbird 3 at launch? Put a high energy density crappily designed battery in it.

Re: People still bought them

Because the problem took quite a while for the design flaw to become widely known. And it's not something that affected all machines.

As for myself, my keyboard started playing up a few months after I bought it.

Millimetre-sized masses: Physics boffins measure smallest known gravitational field (so far)

Tessier-Ashpool

Your electromagnet is vastly smaller than planet Earth. It takes a whole planet’s worth of mass/gravity to defeat your tiny electromagnet. Similarly, the forces in a human arm (that arise through electromagnetism) are enough to raise a pint of beer against the gravitational force of an entire planet.

One more thing: gravity isn’t a force at all. It is the manifestation of spacetime distortion due to the presence of matter. Einstein’s field equations: matter changes the shape of spacetime; spacetime tells matter how to move.

Re: Updates

"ISPs normally update CPEs (i.e., home routers like yours) only if there's a bug affecting the ISPs network or creating an undue number of support calls. Security updates are generally at the bottom of the priorities list, if it's even on it."

Evidence, please. You are massively generalising by saying "ISPs normally".

Perhaps someone from BT would care to respond, if they happen to be watching this thread.

Macs don't get viruses. A computer virus replicates from machine to machine via infected file transmission. Macs don't have those.

Malware, on the other hand, is just as easy to install on a Mac as on any other platform. Less so if you opt to install apps from the Apple App Store.

Mr Thumbs Down, you know Jack Shit about security.

Tessier-Ashpool

Apple TouchID sensor: because security.

Sure you can buy fingerprint sensors on the market. But an iPhone’s sensor is hooked up to its Secure Enclave. Sensor data is *never* accessible to the OS, and authorisation is delegated to the Secure Enclave / sensor combination.

This is far more secure than hooking up (potentially hackable) OS code to a sensor. But the only way that delegation in turn can be trusted is if the physical sensor is trusted by the Secure Enclave. Otherwise you could attach any old fake sensor to the phone that will authenticate every time.

Sometimes, things *should* be tamper-proof.

Re: I actively want to pay!

No subscriptions for me, thanks. All these little subs add up. I will, however, happily pay for new versions of apps if they provide something useful. That doesn’t include paying for bug fixes: I bought something, if it’s buggy it needs fixing free of charge.

Apple iOS 14.5 will hide Safari users' IP addresses from Google's Safe Browsing

Tessier-Ashpool

Re: Proxying

That's not the way it works. Apple don't MITM the browser connection to a website for the purpose of checking a website's safety.

Rather, iDevice will ask Apple to check the safety of the requested website on the user's behalf before a connection to the website is made. Apple will, in turn, make use of Google's API to do that check, without divulging the iDevice IP address to Google.

The result will be yay or nay, and that happens before a connection is subsequently opened to the requested website.

Nothing to MITM. They can't listen in on your session data with this mechanism.

Apple servers would, of course, have the *potential* to correlate an iDevice with websites that the iDevice visits, and log that information for years on end. You know, the kind of thing that Google does.

Apple has no interest in doing that. It's not their business model. You can bet your bottom dollar that the validation data is hashed, scrambled and disposed of so that it doesn't leak beyond the validation service itself.

And if your tinfoil hat is flapping in the wind, you can just turn the feature off in settings.

Personally, I would much rather that Apple perform safety checks on my behalf than have my iDevice ask Google to do it directly.

Re: SQL's JOIN syntax is no harder to learn and more precise to use

Indeed. Use of EF is a time saver that avoids a lot of the humdrum of talking to a back end. Left to its own devices, EF can create some pretty cranky queries, but fairly simple logging/analysis of the generated SQL gives a good indication of where things need to be looked at in more detail. There are also plenty of simple optimisation tweaks you can/should make in high level code before it gets parsed by EF. Another benefit is that you can run the same high level data access code against different versions of SQL Server, and it will take advantage of that server version's capabilities.

Sure, you can make things more efficient if you hand-code stored procedures and invoke them directly. If you've got the time to do that. Or you have a dedicated db team. You could even dispense with a high level language and write your next utility app in assembly language. But we don't do that because life is short, delivery times are short.

Re: Sophie Wilson

In large part I owe my career in IT to the brilliance of Sophie or, as she was then known, Roger.

In the early 80s, there were a ton of IT books available encouraging people to learn how to program. Among those was a superbly crafted manual on how to write assembler for the 6502, and another that contained a detailed disassembly of the BBC BASIC ROM. It was awe-inspiring stuff, seeing how so much functionality had been squeezed into 16KB. The last 5 bytes of the ROM were devoted to the character codes for 'R', 'O', 'G', 'E', 'R' (I forget the exact casing - it's been 40 years!).
