Need for speed? CityFibre punts 5.5 Gbps symmetrical broadband at ISPs

Crypto Monad

Re: I would be happy...

Anyone know why BT don't offer symmetric?

1. So that they can continue to offer "Unlimited" bandwidth packages.

In the download direction, there's only so much bandwidth you can consume: sooner or later you need to watch those videos, or play those games you downloaded. Faster speed mostly means downloading the same amount in a shorter time.

But in the upload direction, there are a minority of people who abuse the network by filling the pipe 24x7, whether that be by hosting bittorrent or by doing full backups of their server every 10 minutes to the cloud. If you apply a transfer limit or FUP, even something huge like 10TB per month, everyone will complain loudly. By keeping the upload speed low, you put a lid on the problem.

Remember that BT/OR are mainly concerned about the 95% of people who just watch Netflix and download games, not the 5% who process 8K video at home and upload it.

2. So that they can allow altnets some of the customers.

If BT/OR were to squeeze altnets completely out of the market, this would be considered anti-competitive, and lead to increased regulation. The altnets have only two selling points: they are cheaper (since they can cherry-pick where to build and are unregulated); and they offer faster uploads. BT/OR is happy to hand off the least profitable, most bandwidth-hungry 5% of customers to altnets in order to show "the market is working".

3. To protect their highly profitable leased line market. Leased lines are still a better grade of service, but for many users, a contended PON symmetric service would be a perfectly acceptable replacement.

37signals is completing its on-prem move, deleting its AWS account to save millions

Re: "Someone Else's Computer" is nonsense

I think the vast majority of people that compare DC costs to cloud costs are comparing, say, a single rack (or less) or a COLO situation. When you have a full row, it's a lot less clear cut in terms of price.

If you have heavy-duty compute needs that require a full row of racks in a data centre - that is, they are actually doing real work and not just sitting there idle most of the time - then this is the case that can work out *much* cheaper than cloud.

Say you are using AWS c5.metal (96vCPU, 192GiB RAM, $4.08 per hour): it only takes a few months before you've covered the cost of buying an equivalent server. Even if you got a 50% discount by taking, say, a 1 year reservation, you've still covered the cost in less than a year; after that you're just paying for the colo. And that's before looking at things like data egress pricing, which is the main gouging point.

Credible nerd says stop using atop, doesn't say why, everyone panics

Crypto Monad

Re: "You might want to stop running atop."

There's also been a lot of crying wolf recently, like the one which claimed to be "unauthenticated RCE against all GNU/Linux systems" and then turned out to be just CUPS. Or the vague announcement of "probably the worst curl security flaw in a long time" which also turned out to be specific to SOCKS5.

Which is why (a) some skepticism is valid, and (b) the personal reputation of the reporter matters more than anything.

Trump eyes up to 100% tariffs on foreign semiconductors, TSMC in crosshairs

Crypto Monad

Re: Elections

I might be missing something, but as far as I can tell, so far Trump has only *talked* about such tariffs, he has not implemented them. This has caused everyone to scramble around to ramp up their US-based production as quickly as possible - which is what he wanted.

In the same way, he has *talked* about invading Greenland, which has caused everyone in a mad panic to spend more on defence in that area - which was what he wanted. There was no need to actually invade.

The Columbians tried to call his bluff, but in that particular instance it was so one-sided in the US's favour that they didn't have a chance. There is plenty of non-Columbian coffee on the market.

Indeed. The processor cost is X, and some part of it is silicon and some is IP.

At least, that's true as long as the license fee remains flat for a given part. If ARM starts demanding a percentage of the sale price of the *final product*, as has been mooted, then suddenly the equation changes.

Rust haters, unite! Fil-C aims to Make C Great Again

Crypto Monad

It depends what you mean by "safe".

If you simply redefined C so that all "undefined behaviour" became "must immediately crash", that by itself would be a huge improvement in safety. At the moment, any C program which triggers "undefined behaviour" can literally do *anything at all*, including reformatting your hard drive, and it is correct for the compiler to allow that. e.g.

GCC 15 to keep Itanium support for now, after all

Re: itanium support.

To be fair, avoiding "dynamic, out-of-order and speculative execution" could have avoided whole classes of of security vulnerabilities (Spectre, Meltdown etc), the mitigations for which can have severe impact on perfomance.

I wonder if Itanium might actually compare reasonably well now, if compared to x86 with all those mitigations enabled?

The open secret of open washing – why companies pretend to be open source

Crypto Monad

Re: Not a universal definition

I think it's disingenuous to blame large tech for somehow biasing the agenda. Authors make the decision between BSD and GPL with their eyes wide open, fully aware of the consequences, often to align with a community to make it easy to aggregate with other similar work - e.g. people who write libraries in Ruby often distribute it under the Ruby licence.

In any case, the world has moved on. Large tech = cloud, and cloud doesn't care if it's BSD/MIT or GPL - they can monetize both equally. Hence the development of AGPL and the like.

Perens is also being disingenuous. He wants to apply, in effect, a tax on all companies that use "open source", and use this to fund his trickle-down empire. This completely turns the head on the whole concept of "open source": all open source becomes commercially licensed under a collective subscription system with a massive price tag (1% of *turnover*) - comparable to regulatory penalities applied for market abuse. This is absolutely the opposite of what anyone who writes either BSD or GPL code wants, and I don't think it has the slightest chance of happening. The large companies will fork the code they use, and maintain it themselves - they can afford to - and stop contributing back.

AlmaLinux shows off its new Kitten

Crypto Monad

Where's Alma going?

The whole point of the original CentOS was that it was almost a byte-for-byte clone of RedHat, without the registration / license fee. If you were running CentOS in production then you had the confidence of it being identical to RedHat.

If Alma starts changing the way they compile things - different instruction set options, different stack layouts - then it's diverging from Red Hat. In an ideal world these things *shouldn't* make a difference, but in some edge cases they might.

How many Alma users want frame pointers - something which the article admits could reduce performance by 1%? And do they want this *more* than they want Red Hat equivalence?

Re: Lenovo please take heed

I am one of the unfortunate that has to carry a laptop around everyday and am always happy to reduce a couple of 100 grams here and there. They also need to ensure that the charging brick is not compensating for the weight loss.

Would you consider a Macbook Air 13" at 1.24kg? That might not be astoundingly light in absolute terms, but the battery life *is* astounding and you may find you stop carrying a charger at all, as I have done. (And in any case, a GaN USB-C charger is very lightweight if you really need one).

I have the slightly heavier Macbook Pro M3 Pro. I do carry USB A-to-C and C-to-C cables just in case, but have never needed to use them for charging away from home.

It is "propelled by renewable hydrogen at the gentle speed of ~12 mph". It's not stated whether they are using hydrogen for lifting as well as propulsion - I hope not.

(But I calculate that climbing to 100,000ft at 12mph would take about 90 minutes, which is not too far off their 2 hour ascent and descent claim)

I also note that it is launched from, and retrieved by, a ship mid-ocean - presumably in order to avoid taxes.

China’s quantum* crypto tech may be unhackable, but it's hardly a secret

Crypto Monad

Re: old school

The theoretical attacks from future quantum computers are against public key systems, not symmetric ciphers.

Therefore, using quantum key distribution for a one-time pad is very wasteful. Just use them for keying a symmetric cipher like AES256, rekey every few seconds, and you're done.

Having said that, all this QDC stuff is just hype. If you are genuinely worried that your adversary is going to do quantum decryption of your key exchanges, then you could create two identical 32GB flash drives filled with random data(*), and have over 1 billion AES256 keys: enough for 34 years at one key per second.

Your problem then boils down to how to stop the USB drive being intercepted and cloned in shipping. The traditional approach is to put it in a suitcase chained to the wrist of a diplomat.
