Oh Snapd! Gimme-root-now security bug lets miscreants sock it to your Ubuntu boxes

Who the hell uses Linux

My advice is

For desktops and laptops use Windows unless you're a Mac fan in which case go ahead. Because you want proper device drivers, power management with working suspend and hibernate etc.

For servers use FreeBSD or a Solaris or similar as you need an operating system rather than a gaffer tape bundle of kernel and userland from different developers. Also a robust filesystem for your data and there is ZFS. You don't need things like snapd . For some applications maybe even go IBM.

The problem with Linux is that it does neither job well though does a reasonable job pretending.

Intel SGX 'safe' room easily trashed by white-hat hacking marauders: Enclave malware demo'd

> tsx is disabled through microcode and sgx support is being dropped entirely.

No TSX was disabled on Haswell as the newly-implemented feature screwed up occasionally creating lock inconsistencies. (Disabled in this case meaning fall back to older slower but safe behaviour.) But in principle it's a good idea. Other architectures have had something similar for a while but Intel is playing catch-up again. But Intel isn't as far behind as with NX. You'll find writable non-executable sections in other architectures decades ago.

Core blimey... When is an AMD CPU core not a CPU core? It's now up to a jury of 12 to decide

jms222 Bronze badge


Regardless of your definition of core the statement that it can't execute n FLOPS in parallel is false simply because of MMX/SSE that can execute 2^n of them.

Even when you can execute 2^n it's very easy for that to be throttled by cache/memory bandwidth because that is of course shared (beyond L1).

And all this stuff has been documented for years and one should always test performance before investing etc etc.

ZFS and rotating snapshots

No substitute for backups but rotating snapshots are great for this sort of thing and various kinds of finger trouble.

I should know better but once wrote some production programming code that continued to use something in /tmp even when it went into use.

London's Gatwick airport suspends all flights after 'multiple' reports of drones

How come one has never landed to swap or recharge and been followed ?

Will we find out that the real problem was an embarrassing baggage handling bug or nasty substance leak ? Of course they can support their story by actually flying drones.

W7 drive mapping

Now that drive mapping has come up I wonder if the problem my W7 virtual machine has gained this autumn is related. It comes up asking something about restoring drive letters in the background and no matter what I do it shuts down or reboots again.

No network drives or anything like that in use on the VM.

I have reverted to a good September snapshot several times but can not successfully apply newer updates.

Cambridge Fibre

I have told a local company https://www.cambridgefibre.uk to proceed and claim my business £3k government voucher. The service uses G.PON and they claim weeks not months. But the point is it's a small local no-nonsense company (Netservers) and my house is in just about the right position on their main trunk and I have a BT pole in my front garden they can apparently piggyback.

Secure boot that can be disabled

is just an oxymoron.

jms222 Bronze badge

Damned if they do

We've had the same argument with PCs for years.

Criticise them for the ease of having bootloader malware then when they do secure boot stuff to guard against it criticise them again.

Consistency anybody ?

You simply can't have both the ability to boot any OS that changes from week to week and security against bootloader malware.

Good riddance to them.

Samsung's graphene batteries promise to charge five times faster – without exploding

> If I had a phone that took a day to charge

Overnight rather than a day.

Well if I can charge my car while I sleep and it can do enough miles the next day before I need to sleep again and can do this every day for a few years without significant degradation that is sufficient. Also doesn't cost as much as a Tesla. (Ignoring drive-sharing case.) We're just about there (60kWh Leaf and a few other models) which is great.

Military levels of security

Give me a few minutes with a screwdriver and a tube of glue and I'll show you how far you can get at least with USB and optical drives.

There are also ways to disable USB and USB storage in operating systems which assuming you prevent booting from other stuff goes a long way.

Access is not the same as bulk export

> He was an auditor. He needed access to the full payroll data to do his job.

and should have been able to view what he needed in summary and record by record sitting at a terminal on the company's premises. He never needed the ability to insert a USB device and bulk export to it.

For that reason I think Morrison's are at least partially to blame.

Leeds hospital launches campaign to 'axe the fax'

jms222 Bronze badge

It's all true

I've had to get my G.P. to fax a referral through to the hospital before. The system is shit.

Similarly the "electronic" prescription service seems to delay prescriptions by whole days.

Where the surgery have emailed me letters _they_ sent they are scans of prints.

In order to get a prescription waiver card you get a form from the chemist, take it to the G.P. (who actually issues the prescriptions to the chemist) then send it off then get a card through the post which you take back to the chemist. It's as if they're on a mission to waste as much taxpayers' money as possible.

Throw the license in the bin

I am no legal beagle but to me it's very simple. The microcode is necessary to make the device you have already bought work better. It can't be resold and can only be used on a specific device.

So assuming you want that and do due dilligence just use it and get on with life.

Virgin Media Hitron

Recently moved from Virgin Media residential to Business "Essentials" because the latter is cheap especially for the VAT registered (otherwise shit).

As part of backing up I shunt some data over the (wired) network through the router for the simple reason that it's there and avoids having other switches powered up. With my old Super Hub (model 1) the rate was about 120MB/s as expected. Did the same at the weekend through the Hitron CGNv4 thing and got half of that with gaps of several seconds with almost zero rate. Same procedure with the same equipment as before otherwise. Tried some pinging and noticed _some_ pings taking several milliseconds. So I wonder whether the wired side is not (like) a switch chip as one would hope but maybe goes through the Intel rubbish.

Also after the slight rain we had last week (and I do mean slight here in East Anglia) the connection went for a whole day and after the main external fix even a soft reboot of the thing did not recover it and I had to power cycle. So much for the many 9s availability they quote.

There is no proper installable device driver system

Unlike Microsoft Windows, Linux has absolutely no concept of an installable device driver system.

I mean you plug something in and the appropriate driver is fetched based on USB or PCI IDs even if this sometimes takes a minute or fails.

Instead if you wonder where those Gigabytes went it is because you have

* Every possible X server

* A kernel with tweaks and loadable modules for every CPU (and I don't mean those from Intel and AMD), every motherboard and every USB device the kernel ever catered for

* Every timezone

* Every locale

* A really flaky system of boot relying on initrds that seem to get re-build several times per update so now you have hundreds of megabytes in /boot alone and the thing won't boot when these go wrong which they do

Chisholm trail

Our council had contracted Carillion to manage https://www.greatercambridge.org.uk/transport/transport-projects/chisholm-trail/ along with Tarmac. Luckily Tarmac have taken over their part (i.e. the actual work) but guess who the council have got in to do "management".

The local Chisholm Trail has been discussed for decades (along with re-opening Chesterton Sidings as Cambridge North which has finally happened) and should be great when done.

I regret not standing up at the last local meeting I went to and asking that without meaning any disrespect to the people present what does the council intend to do when Capita go the way of Carillion.

All low power devices

All modern battery-powered devices have this compromise between being able to power up properly, performing at benchmarks for willy-waving purposes and not costing too much.

The power supply itself is also a balance between being able to charge and power the thing at full tilt and itself being not too expensive or large. For example when the Microsoft whatever was found to discharge even when powered under load a little while ago.

Nothing new here.
