Apple might be 'collateral damage' in US and China trade dust-up

Gordan

Re: Shooting onself in the head

"A fair point, but lets face it, at the moment somebody in China would copy your product anyway if there's a significant domestic market."

Similarly with Zotye SR9 (Porsche Macan clone). Interestingly, the Porsche dealers in China aren't at all concerned, and for a very good reason - anybody who can afford even a used Porsche won't be buying a Zotye knock-off.

The thing to take away from this is that competing on the cheap end of the market in a place where labour is much cheaper is a foolish thing to be attempting at the first place. If you can't compete on quality first, at least earn some good karma by not expending more of the finite planet on making yet more worthless tat.

Cost of doing business in China, it seems. The only winning move is not to play.

For what it's worth, some headway toward addressing that had been made at some point, as short lived it may have been:

DB dev waggles GPU-dosed POWER9 server at data warehouse crowd, yells: SQream

Gordan

You'd be surprised. The workload nature of databases is that you need a _LOT_ of fast memory. GPU has loads of compute on it, but VRAM is far more constrained compared to system RAM when you can buy a server with 1TB of RAM.

So provided your data chunks reasonably cleanly into VRAM sized portions, you can gain some advantage there, but then there's the overhead of loading that data from system RAM into VRAM, where you get a significant hit.

The reason databases aren't commonly GPU accelerated is because it would only be faster for a small fraction of atypical workloads, and massively slower for most typical workloads.

Contractors slam UK taxman's 'aggressive' IR35 tax reforms

Gordan

Re: Loan Charge?

"It is also written in law that HMRC can go back up to 20 years if they believe you have been committing tax evasion, so the legality of a loan you are not expected to pay back is brought into question."

Except this is not tax _evasion_, and such schemes have not been ruled illegal. So the 20 year rule seems like it should not be applicable.

Re: Loan Charge?

"The law that sets speed limits is the Road Traffic Regulation Act 1984 (you'll want to look at section 6)."

OK, I'll bite, and I just looked at the exact wording. The gist of it is that it states that it is not permitted to exceed the speed limit. Nowhere in that document does it explicitly state that it is permitted to drive under it. So the analogy does in fact seem to hold, and the general principle of the law is that everything that is not forbidden is permitted.

Re: Loan Charge?

"There is no law saying that EBTs were acceptable practice."

And there is also no law saying that doing 70mph on the motorway is acceptable practice. Anything that is not prohibited is permitted, that is the nature of laws everywhere. This income was legally declared, open to HMRC scrutiny, and could have been challenged any time since. The fact they did not do so in even a single case within the time period in which they were obliged to do so implicitly makes it legitimate. So the comparison is in fact absolutely spot on. It really is equivalent of retroactively reducing the speed limit and then sending everyone who exceeded the new speed limit going all the way back 19 years speeding tickets.

Official: The shape of the smartphone is changing forever

Gordan

Re: Wouldn't it be nice ..

Frankly, it'd be nice if sensibly sized (<= 4") phones of decent spec were to become available again. If I want a device that required both hands to operate, I'll use a 9" tablet. For a phone, I want to be able to reach the top corner with my thumb easily, and being human my thumbs happen to not be 6" long.

As for becoming taller and narrower, this is again the consumer optinion being shaped to maximized profits - the less square the screen, the fewer pixels there are for any given diagonal size. Fewer pixels means higher yealds, which means lower cost and greater profit margins. We have seen this on desktop displays where things went from 16:10 to 16:9 and more recently the trend toward "ultrawide" screens.

Registry to ban Cyrillic .eu addresses even if you've paid for them

Gordan

Not only is it a dick move, the letter ю is from russian and doesn't exist in some cyrillic alphabet languages. So it's even more of a dick move because it opens an additional can of worms, e.g. whether there should be a 3rd TLD for eu, this time ".ey" (y us cyrillic u).

It sets a terrible precedent for effectively going back to code pages and character sets like they were before UTF-8 was invented by effectively only allowing domains that use the same character set as the extension. What's next, are they going to, say, ban škoda.eu because š isn't ASCII?

Visa Europe fscks up Friday night with other GDPR: 'God Dammit, Payment Refused'

Re: Cashless society

"No, your UK debit card won't work on the European network."

I call bullshit. I take a road trip across Europe every year and have to buy fuel, food and on occasion get cash out of an ATM, and can confirm that my UK debit card always works just fine in France, Belgium, Netherlands, Germany, Austria, Slovenia, Croatia, Serbia, Hungary and Bulgaria. Also always worked fine in US. Further, you pre-emptively contradicted your own previous statement on this very subject by saying:

"... card cloned and lost several hundred quid as a result. We only got it back (my mum was too embarrassed to argue) when I made a complaint, as the card was used in the Netherlands and then in Malaysia an hour apart"

So the cloned card did in fact work in Netherlands and Malaysia?

HMRC opens consultation to crack down on off-payroll working in private sector

Gordan

Re: Risk vs Reward

"Does anyone know whether HMRC have ever responded to this frequently-made point about benefits?"

Not officially, but self employed (note: important distinction vs. ltd. company) people have in the past successfully sued their clients for statutory holiday pay and pension contributions after they were engaged as self-employed contractors and then found by HMRC to be caught by IR35. So there most certainly is legal precedent for it.

The real kicker here is that the client-side determination of IR35 status here is also coupled by the client's insistence that the contractor be operating through a ltd. company rather than as self-employed. This key point allows the client to dodge the employer's taxes and palm off the responsibility for them onto the ltd. contractor.

In other words, the entire setup is actively rigged for the government departments to dodge both employer's statutory liabilities/obligations _and_ employer's taxes and shift them onto the employee.

Re: Risk vs Reward

THIS.

The test for employment vs. self employment should be made the same for both employment rights and tax purposes. If your client isn't paying you statutory holiday pay and pension contributions, you are self-employed and should be taxes as such. If they are, you are employed, and your client is liable for deducting your taxes at source and providing at least the minimum statutory benefits.

Anything else effectively amounts to expecting a employees to pay employer's taxes.

Oh, great, now there's a SECOND remote Rowhammer exploit

Gordan

Re: Remind me what memory ECC is for

The simple fact is that ECC _does_ make rowhammer ineffective in the few cases where it might plausibly be exploitable.

Flipping one bit is hard. Flipping two bits in the same memory row at the same time is exponentially harder. Flipping three bits is exponentially harder again.

ECC memory can:

1) Correct 1 bit errors transparently

2) Detect 2 bit errors (causes an NME and typically a kernel panic)

It takes flipping 3 flipped bits in the same row of memory to introduce an undetectable memory corruption with ECC memory. And flipping one is difficult enough. Not to mention you have to get extremely lucky to be operating on a row of memory adjecent to the one you are interested in corrupting.

TL;DR: Don't lose sleep over it, especially if you have ECC memory.

Overbuild BS

"Providers could end up targeting the same lucrative areas to invest in fibre, rather than creating a more geographical spread."

It is a GOOD thing that they are all targeting the same areas. It means there will be competition wherever it is available, forcing providers to ensure they are providing a good quality service at a competitive price. Once they cannot take the piss by charging sky-high prices (anyone seen FTTPOD prices recently?), they will have to spread further and further out from cherry picked areas in search of more revenue.

Overbuild is exactly what is supposed to happen, and it is a good thing.

Re: Dumb question?

"ditch the Hub 5 and replace it with a decent router/AP of your own"

The problem with the HH5 isn't the hardware. The hardware is actually pretty good. The problem is their customized firmware after a specific version. Never had any problems until that July 2016 firmware update. Before my contract was up I flashed it with OpenWRT (soldering required to get serial console up), and that worked just fine.

Re: Dumb question?

It's a major achievement for their customers that they even acknowledged that there is a problem.

BT Hub 5 got a firmware update back in July 2016 that made it unstable. It would reset under load. I was setting up backups at the time, and the uploads to the cloud would never complete because of this. After arguing the toss for a few months they sent me a replacement BT Hub 5, and that worked great for a week - until it, too got the same firmware update, and started resetting 100+ times per day.

After all this, I got one of the L2 support engineers to finally confirm there is a firmware big, and that they are working with people who work on the firmware to resolve it, but they I got a call back from his boss who flat out denied everything the one and only helpful person they have working for them told me. His advice? Get a standalone VDSL modem instead of using the one built into the BT Hub 5, but that was still totally not an admission of a problem (because there would be more people reporting it if I wasn't imagining it, and the 100+ hub resets per day they could also see from their side were obviously just a shared illusion).

The only bit of good news in this story is that my contract term was coming to an end so I took the opportunity to mentally note to NEVER sign up with BT again and switched to a different ISP.

If you are looking for something that is specifically in the Pi form factor, Asus Tinkerboard is much more advanced. The only downside of the Tinkerboard is that it's SoC is 32-bit, but that's hardly an issue on a board with less than 4GB of RAM.

Why? It's not like you'll get that much I/O to/from the micro-SD card or a USB attached disk.

Meltdown/Spectre fixes made AWS CPUs cry, says SolarWinds

Gordan

Re: I don't get it

The problem is that switching context is in the order of magnitude of 100x slower in a VM than on bare metal (addding microseconds to nanoseconds).

That is why some workloads virtualize with minimal performance hit (few threads, low concurrency, mostly userspace CPU burn), and some workloads virtualize extremely poorly with a huge performance hit even without meltdown patches (anything highly concurrent such as compile farms, databases). I have measured performance hit from virtualization on some such workloads to be upward of 30% - and that was before meltdown patches came into play.

Cool disk drive actuator pillar, Seagate – how about two of them?

Gordan

TL;DR

It won't make any difference to sequential I/O, including RAID rebuilds.

It will, however, double the throughput on random I/O.

This applies to both reads and writes, all that matters is whether the I/O is sequential or random.

Dawn of The Planet of the Phablets in 2019 will see off smartphones

Gordan

Re: Pocketalypse

I have to say I'm dismayed by the trend of moving toward phablets. IMHO, the ideal form factor for a phone is about 3.5" (ZTE Blade). I grudgingly upgraded to a Moto G (1st gen) when Android 2.x went out of support and Android 4.x was never ported to it.

I find Moto G's 4.5" size unnecessarily big and bulky, but have been resisting upgrading to a newer phone because finding anything that is:

1) not bigger

2) supported by LineageOS

is pretty much impossible at the moment.

Until the market provides a sensibly sized device, it won't be selling me a new phone.

MPs draft bill to close loopholes used by 'sharing economy' employers

Gordan

Re: More Info Please Or What's it Really All About

This relates relatively closely to the "lump of labour" fallacy.

The reality is that two things will happen:

1) A non-trivial fraction of the work currently done by people on 0-hour contracts will end up not being done at all because the net productivity isn't worth the cost of complying with extra regulatory requirements.

2) The remainder that does get done will end up being done by larger suppliers of such services with fewer employees for whom they have enough work to keep at full utilisation.

The net result is that larger business will squeeze smaller ones out of the market, and those who end up not getting one of those full time contracts with a larger supplier are going to end up on the dole and increase the burden on the state.

In other words, while it sounds like socialism for the worse off individuals it is actually corporate socialism helping only bigger businesses by reducing competition.

It's the same reason why big business generally supports extra regulatory requirements because they can afford to implement the required compliance, whereas for an upstart the burden of extra regulations means they are unable to grow to become a competitor.

Re: Beer

"So you're saying a Linux using an initramfs can mount a userland filesystem (say FUSE-based) as /?"

Yes you most certainly can. I have patched zfs-fuse with that functionality and wrote dracut modules for it. I use it on all of my ARMv5 Linux systems. My patched and updated branch of zfs-fuse is in the latest Fedora.

Also, Grub 2.x already has enough zfs support in it to boot the kernel and initramfs from a ZFS file system, so there really is no barrier for using any variant of ZFS (fuse or kernel based) for the root file system.
