UK voter data within reach of miscreants who hacked Electoral Commission

That might have been the goal, but it seemed to backfire:

And yet they force OAPs (many who have neither driving licence nor passport) etc to get photo ID to vote now in some gerrymandering goal of stopping fraud?

China's great CPU hope – Loongson – may be only four years behind Intel

Paul Crawford Silver badge

It will be interesting to see how the Chinese proceed with this. Clearly it is in their interest to have some autonomy from the west, and probably good for the world in general to have some real choices and diversity of supply chain.

I would like to see a truly open RISC-V design becoming available that would marry well with open source OS, and that could work well for China and everyone but ARM+Intel, but the Devil is always in the detail*

Thanks for that article.

The Voyagers were and still are an amazing achievement and show what good engineering can do, they really are a testament to those behind a huge project that no doubt has seen more than one generation come and go from inception to conclusion. Similarly the DSN 70m dishes were a huge project in both cost and engineering, but years on, and numerous upgrades to RF and signal processing over the years, they are still #1 in terms of deep space comms. I don't know if anyone has looked at the value for money, but those have definitely repaid in terms of over a half century of science.

How many of us will ever do anything that has such a lasting impact on mankind?

Japan, 2003 or so. Sun box with a USA keyboard but machine configured in Japanese. We have been given the root password to work on it, but nobody to ask how to actually type it in! We had software (including device driver) to install and configure so in frustration Ctrl-Alt-Stop (from distant memory...) then forced reboot bringing the machine to default US English so we could get on with the job.

A room-temperature, ambient-pressure superconductor? Take a closer look

Paul Crawford Silver badge

Re: SQUIDS could be made to work without a cooling system.

I'm not sure it is just the superconducting aspect, I suspect the very low temperature also reduces thermal noise which makes quantum-level signal detection a possibility.

Paul Crawford Silver badge

Re: Even if its not a superconductor

Forgive me if I am completely wrong here, but I thought many of the "high temperature" (relative to liquid He) superconductors were very poor (i.e. lost superconductivity) at handling high currents or high magnetic flux levels. I.e. they are super conductors for modest currents, but no use for power distribution levels where such a saving would be of great commercial and environmental benefit.

ESA sees satellite-based air traffic monitoring on near horizon

Paul Crawford Silver badge

Re: I wonder what level ....

Yes, it can be done and is fairly easy (for a given definition of "easy" in hardware design). Depending on SNR it is not too difficult to resolve the timing of a data stream to around 1/10 of a bit-period, so in your 1Mbit/sec case that is 100ns and about 30m in distance. Once you have multiple observations and can do a least-square or similar fit, often using a Kalman filter or similar to estimate the target dynamics, you can typically get down another factor of 3 or so depending on the geometry (GDOP), so you are looking at under 10m precision.

Plenty good enough for most objects in the sea or air, but not quite good enough to resolve per-lane on multi carriageway roads.

Paul Crawford Silver badge

Re: Is this a breach of ESA's rules ...

The also have a site in Glasgow and, while the UK has exited the EU, we are still participating in many ESA budgets so gets some pork return.

Paul Crawford Silver badge

Re: I wonder what level ....t

It is even simpler, you fit the satellite with a GPS-disciplined oscillator and time source, then it has the ability to measure Doppler and time-of-arrival of data to near-atomic master clock levels.

Send summary messages down of that using usual telemetry channels and somewhere else they can all be correlated and triangulated on the basis of the measurements.

Seems that software that can poke in to all of your devices to "manage" them is also a most excellent vector for attack.

Microsoft’s Dublin DC power plant gets the, er, green light

Paul Crawford Silver badge

Re: Potentially greener?

Given the description and reluctance to use it at other time it probably is a big dose of open-cycle gas turbines.

CCGT would be better, around double the efficiency, but they seem to be large units. Given the high cost of gas it surprises me they are not going for high efficiency, but I ma sure someone has worked out the minimum spend to suck Dublin's electric most of the time and just chip in at high cost when no other alternative is available.

Linux has nearly half of the desktop OS Linux market

Paul Crawford Silver badge

Re: Installfest

Wow, what a leap of interpretation that the OP did it without consent?

For family and friends I now only support them if its a Linux distro as I have had enough of Windows malware and the stupid tricks MS have pulled over the years. I can set up a fairly locked-down Linux box and come back 5 years later, even when its gone out of support/updates, and it still works without malware on it. With Windows and paid-for AV I still found some family members had the box infested within 3 months of use.

I have some Windows machines and VMs for software that needs it, and I don't push Linux on folks that need Widows for specific use-cases, but my life is too short and precious to fire-fight the support problems that come with that territory.

Broadcom asserts VMware's strategy isn't working and it basically needs rescuing

Paul Crawford Silver badge

Re: "VMware alone can't get that job done"

VMware managed to start with a fantastic product that was really the game-changer in terms of virtualisation for common & useful OS (I'm ignoring decades of mainframe stuff here...) and from there on it went downhill as the management tools sucked and relied on crap stuff like specific versions of flash, etc. Which is pretty sad. Basically as the sales grew the products declined.

But I strongly suspect nobody will enjoy the results of a Broadcom take-over, bar a few shareholders.

Re: All The Fun of C and C++

And who, pray tell us, is rewriting it all in a new language?

Paul Crawford Silver badge

I was wondering the same, but the "home firewall" group seems odd to me. Yes, you might pick up the kit cheaply but the power draw (and hence running costs) will mount up and I hardly see any home needing huge-scale throughput. After all openWRT or pFsense can be deployed on adequate and low-power hardware for probably less then eBay prices for those firewalls.

Let's have a chat about Java licensing, says unsolicited Oracle email

Paul Crawford Silver badge

Re: Simple solution

Better still purge your business of ALL software from Oracle.

In a past job we had Sun stuff, once it became Oracle we knew it was game over so all that was not already paid for / permanent was decommissioned and free options from Linux and similar used instead. OK, not everyone has that luxury as they may lack developers or be tied to COTS stuff that only works with X.Y.Z version (hopefully from pre licence change!), but if you are using Oracle they will come after you for serious money have the the legal form for making you pay.

Re: This isn't the Brexit we voted for.

I'm guessing that is sarcasm.

But indeed the whole problem is Brexit, or more precisely the "free movement" that was used to rile gammons about EU workers taking their jobs so it had to end.

And now we are short of care staff, NHS workers, fruit pickers, HGV drivers, etc, as many EU folks decided to head home than live in the home office 'hostile environment' and my oh my we found many who voted for that are unable or unwilling to fill those posts at market rates, while moaning about costs and not wanting to pay farmers, etc, more.

Of course we have an imploding Tory party that can't see beyond Brexit goals, and a feeble Labour party that is afraid of the 'red wall' losses if they speak up.

UK government hands CityFibre £318M for rural broadband builds

Re: That's a lot of money

Have you asked Openreach how much they charge for Excess Construction Charges?

From memory something like £140/m for any work in tarmac and £40/m soft dig (inc VAT), and that is before you add the cost of the fibre at about £5/m (applies even if duct already there, etc).

How a dispute over IP addresses led to a challenge to internet governance

Paul Crawford Silver badge

Re: The issue with V6 is... NAT

Can you get IPv6 -> IPv4 NAT so all of your internal addresses are from, say, 10.x.x.x block and they routed outside on whatever IPv6 addresses are allocated?

Presuming here that very few folks considering security actually want incoming connections by default, only as set up in the router via port-forwarding or whatever means used for specific needs.
