North Korea Denies Involvement In "Righteous" Sony Hack

johnw From a hotel in Thailand (85 comments)

The latest reports indicate that the hackers worked from a hotel in Thailand.

I hope they weren't being charged by the gigabyte for using the hotel's WiFi.

Ask Slashdot: Why Is the Power Grid So Crummy In So Many Places?

johnw Re:Have a look at getting your own power source (516 comments)

You could take care of some of the daytime failures with solar (and evening if you get some batteries).

Be aware that for a solar installation feeding power into the grid, you are generally required to have a control system which immediately shuts down your solar generation if the power grid fails. This is for safety reasons (chaps working on the line don't want to find there are still unexpected volts there after they've shut off the supply) and because your system will start to go blue in the face very quickly if it tries to power your entire neighbourhood.

You could have a more sophisticated control system which merely disconnected you from the grid and powered your local devices, but that would of course require some storage of power as well because your load would practically never match your generation. The vast majority of small solar installations do not do this.

What is your computer most often plugged into?

johnw Re:UPS (236 comments)

Which is why I roll my eyes at the people proclaiming their UPS goes on their cable modem and firewall, not their computer.

Some of us have a UPS for our cable (well, FTTC actually) modem and firewall, and another for the computer. I prefer things to just keep working.

Ask Slashdot: How To Unblock Email From My Comcast-Hosted Server?

johnw DKIM makes a difference (405 comments)

I found a while back that GMail started flagging e-mails from my server as spam, even for a business customer who had explicitly white-listed my server in their configuration. Setting up DKIM message signing cured that.

Yahoo on the other hand are complete fuck-wits when it comes to spam detection. I've tried in the past to follow up random spam flagging, and they just give you the runaround. I filled in a complicated form with full details of the erroneous spam flagging, and they responded with a request to send all the same information again to an e-mail address, and then when I did the notification bounced because the e-mail address didn't exist.

The only thing you can do with people who use Yahoo for e-mail is teach them how to look in their spam folders. When they do they'll find lots of other non-spam there too. That's the moment to suggest they move to a proper e-mail provider.

BBC: ISPs Should Assume VPN Users Are Pirates

Intel's 14-nm Broadwell CPU Primed For Slim Tablets

johnw Re:Thank GOD (96 comments)

Because most people sit WAY too far away from their TVs - even 720p is "retina" resolution - increasing resolution does absolutely zip because they can't even resolve the added resolution.

A rough guide is about 1:1 screen size for 1080p

Way too far away from their TVs for what? If your criterion for deciding the correct sitting distance is whether or not you can tell 720p from 1080p then perhaps you have a point, but if the object of the exercise is to watch television in comfort then 1:1 is just silly.

Enraged Verizon FiOS Customer Seemingly Demonstrates Netflix Throttling

johnw Re:Alternative explanation (398 comments)

Thats how the internet is paid for. The sending provider pays the receiving provider for the bandwidth, and this is the only rational way it can be.

Really? I'm only an end user, but my experience is that the charging is the other way round. Traffic to me is metered (and I pay for) whilst traffic which I originate is un-metered.

Well, you could click on it for yourself (you don't have to place an order - just click the relevant radio button and then hit submit) but for those who want a short cut, the form then fails field validation with the following message.

"Sorry, for a censored internet you will have to pick a different ISP. Our services are all unfiltered."

Microsoft do still support XP. The real change that has happened is that Microsoft have gone from providing free support to charging a lot of money for the same support. That's all.

School Tricks Pupils Into Installing a Root CA

johnw Re:In their defence. (417 comments)

They have low-tech means of circumventing the filter, mostly involving spending an hour going through page after page on google until they find a site not blocked.

Hardly low tech!

I too work in a school, which also implements all sorts of paranoid filtering on the school LAN. (Don't know about root CA certificates, I've never looked.)

Increasingly however, what the school does is utterly irrelevant. Almost all the students have their own completely independent access to the big bad 'net. They have phones with full Internet access, dongles for their laptops, and even laptops with SIMs built in.

It'll be a while before school authorities recognise that they're standing with their fingers in the tiny remains of a dyke, the rest of which has long since been washed away by the incoming tide. Until then, we'll still find ourselves unable to access all sorts of random and silly things in the classroom. I was refused access to the text of Rudyard Kipling's "If" the other day.

The Ever So Unlikely Tale of How ARM Came To Rule the World

The Ever So Unlikely Tale of How ARM Came To Rule the World

johnw Re:More like 34 years (111 comments)

It was still an odd decision to design their own CPU for the successor to the BBC Micro. A more obvious and less risky move would have been to use a 68000 series CPU as a successor to the 6502.

IIRC, they experimented with a chip called the 32016 (or 16032) as a possible successor to the 6502, before deciding to start again from scratch and design their own.

All the 2nd processors for the Beeb - Z80, 6502, 32016 or ARM looked exactly the same from the outside, although when you opened them up the Z80 and 6502 were mostly air, whilst the ARM prototype was stuffed to the gunwales. It didn't even have go-faster stripes or a front air dam.

The odd thing was, early ARMs seemed to manage to produce much more bang for your MHz than x86 chips. An 8 MHz ARM2 ran rings around a 25 MHz 80386. What let them down then was the lack of a floating point co-processor. Later on the relationship seemed to reverse.
