England's village green hydrogen dream in tatters

Spanky_McPherson

> where do you put your heat pipes?

Could they not be attached to an external wall, like people do today with air con units?

Agree we will never meet the 2050 deadline though.

Spanky_McPherson

Well, duh

It should be obvious to all that hydrogen-based heating is (edge cases aside) uneconomical.

We're really going to take our renewable electricity, turn it into hydrogen, then set fire to it, giving you maybe half of the original energy back as heat? Or we could, you know, run a heatpump which returns *3 times* the orignal energy as heat.

Yes, we need fatter pipes and larger radiators, and somewhere outside for the gubbins to live. The fact that new houses today are still being installed with microbore pipes that cannot be used by heatpumps should be a scandal.

Raspberry Pi 5 revealed, and it should satisfy your need for speed

Re: Expensive

Unless you're generating your own electric, you might need to redo that calculation. At 60W continuous, you're using 525kWh per year. if you're paying £10/year it means your electricity must be about 2p / kWh.

My electric bill for that "low powered" server would be *fifteen* times higher, some £150/year.

Preview 9 of Visual Studio for Mac is out as GA approaches

Spanky_McPherson

Not really for C++ programmers.

Visual Studio for Mac is the evolution of the original Xamarin Studio, which was very much a C# IDE rather an a C++ IDE.

If you're a Windows C++ programmer, no need to go anywhere near this.

Microsoft veteran demystifies Abort, Retry, Fail? DOS error

Spanky_McPherson

Re: There should only be Retry and Fail, the other two aren't needed

I'm sure Dave Plummer and the MS-DOS developers had good reasons for doing what they did.

It's a little condescending to just show up and claim that you know better than them.

I also used to have the "Everything that I don't understand is easy" attitude, but we should try to be better than that.

Re: Arianespace - long term plan?

The Arianespace Vega, which can carry 1400kg, costs $37million per launch according to Wikipedia.

The Electron can carry 200kg and costs only $6 million.

For small payloads, SpaceX is definitely not the cheapest option.

Re: I know this

For some of us, the point is to be able to work from home.

For others, it is to binge watch pirated movies over the internet... 'nuff said.

Re: I know this

Though if anyone is thinking of using a 3G hotspot to replace a broadband connection, be aware you will likely not receive a publicly routable IP address.

This will mean any application that requires you to open a port on your router won't work. For example, you won't be able to do remote streaming from your Plex server.

You're on a Huawei to Hell, US Sec State Pompeo warns allies: Buy Beijing's boxes, no more intelligence for you

Spanky_McPherson

But why are they inspecting the source code?

I don't think it's feasible to guarantee that the binaries running on the network gear are generated from the inspected source code.

Unless you're planning to desolder all the flash chips and test them individually, who's to say what's actually running?

The OS can simply report whatever the attackers want it to, including lying about what binaries are running.

Spanky_McPherson

Re: If everything's encrypted, what's the problem?

Well, because knowing who is talking to each other is useful intelligence, even if you can't decrypt the actual data.

Oof, are you sure? Facing $9bn damages, Google asks Supreme Court to hear Java spat

Re: @Doug S ... Better if they refuse cert

No, its really not like that. To use your own metaphor, Google created a completely different PCB, but used the same pinout as Oracle's PCB.

Largest ever losses fail to dent Tesla's bulging order book

Re: Lose a little on each one...

Oh for goodness sake.

Tesla make a gross profit on each car. Their losses are due to capital expenditure.

"Why the petrol company decided they needed Windows on something as simple as a petrol pump I'll never know."

I think the business case for running Windows on petrol pumps involves showing ads to people who have no choice but to stand in front of them for several minutes.

Re: already 2 checks ahead of the competition ...

@JimmyPage...

Totally agree about the shiteware that comes preinstalled on many phones these days, but just buying unlocked phones doesn't guarantee lack of shiteware. For example, the Sony Z series are great - apart from the shitty Sony apps that can't be uninstalled.

It now looks like WileyFox are going down the shiteware route - I updated mine a couple of days ago and now it won't stop spamming me about bloody Skype every time I open the dialler.

A perfect marriage: YOU and Ubuntu 16.04

Spanky_McPherson

Re: kubuntu 15.10 to 16.04 works but 12.04 to 16.04 does not

12.04 to 16.04 is not a valid upgrade path. You have to go via 14.04, I believe.

Spanky_McPherson

Would be nice if it didn't hang on boot

Doesn't work for me - it tells me the filesystem is clean and then hangs. Not even a login prompt.

Fortunately it was a clean install on a new drive, I can just pop the old drive back in.

I might raise a bug if I can work out where I should do it, it's not immediately obvious.

Microsoft sets date for SQL Server on Linux

Spanky_McPherson

Re: This is actually largely irrelevant

@Doctor Syntax

Yes, I agree with you. Most folks using a commercial database (e.g. Oracle) will continue to do so rather than move to SQL Server on Linux.

I look forward to seeing if Microsoft can make an impact on Oracle's market share. It has a chance, assuming it will be much cheaper than Oracle.

Spanky_McPherson

Re: This is actually largely irrelevant

"there are better free alternatives out there"

er, no.

Core database functionality of the free databases may be comparable to SQL Server, but they are nowhere near in terms of the full package.

To pick some random examples, where are the better free alternatives to SQL Server's multi-master replication? What about Analysis Services? I'm sure I could think a dozen features of SQL Server that are better than the free alternatives.

(Last time I used PostgreSQL - admittedly a long time ago, it required a database dump and restore when upgrading versions. Honestly I would still use it, but better than SQL Server? Nope.)

First working Apple Mac ransomware infects Transmission BitTorrent app downloads

How to mitigate the encryption malware?

I like the way the malware can encrypt Time Machine backups.

I am considering changing my Time Machine configuration so that it writes to a Linux box on the network rather than an external disk, and where I can take daily ZFS snapshots of it - presumably this would mitigate against this type of malware.

I believe this configuration works , but is unsupported by Apple.

Spanky_McPherson

But what was the original vulnerability?

The actions taken (i.e. release a new version of the affected application) only make sense if the original vulnerability in the web server has been identified and patched.

Otherwise, what's to stop this new version from getting infected in the same way?

You shouldn't use *any* software from this developer until the question is answered: what was the actual vulnerability, and how was it fixed?

Uber's technology is undeniably brilliant???

Living in the provinces, I have never used Uber. So can someone tell me what is so special about the technology?

From what I have read it seems pretty straightforward.

At this price it is competitive with storing the data yourself on a couple of hard drives.

There doesn't seem to be much information on the redundancy/reliability though.

Amazon reveals $50 Android-ish Fire tablet it will axe in two years

Re: US=$49.99, UK=£49.99

Er, no. $49.99 is very different from £49.99.

Ex-VAT, the UK price is £41.66. This is the number we are comparing. According to google that is $64.97.

So it *is* a significant rip-off.

The last post: Building your own mail server, part 1

Spanky_McPherson

But running a mailserver from home simply doesn't work...

My experience was the same as some other commenters - (some) outgoing emails never arrived at the destination.

I suspect that some SMTP servers would silently drop email based on the source IP address (i.e. they knew it was a residential ADSL connection)

It made the whole exercise pointless, and I ended up on gmail.

How the FLAC do I tell MP3s from lossless audio?

Re: "Everything between sample points is lost"

This sentence is fundamentally wrong. Nothing between the sample points is lost. The continuous analogue signal can be perfectly recreated from the samples.

Please please watch this excellent video made by someone more knowledgable than anyone on this forum: (watch between 4:00 and 6:00 if you don't have time to watch the whole thing)

https://www.youtube.com/watch?v=cIQ9IXSUzuM

(For the pedants, yes, this assumes that the signal being sampled does not contain frequencies above 22.05kHz. Obviously this filtering is always done to the signal prior to sampling)
