'Doomsday' asteroid Apophis more massive than first thought

Re: So Unlucky.......

Your chances of winning the lottery will be much better assuming you enter twice every week for ~23 years.

I'd make it ~~1 in 6000 ( if you just spent £1 a time )

Good luck !! ( either way). Of course your number might be drawn the day the asteroid falls.

"isn't it a bit of a coincidence"

The only coincidence I can see is that between the rock and the Earth. Don't know how many countless others have passed by in the millenia when we couldn't track them. There are a lot of asteroids moving in chaotic orbits , even though the sol system is very big given enough time one will hit again.

"what error I have made in reasoning"

I'd think the error is assuming the asteroid has been passing close to Earth regularly for millions of years - it may be relatively new, having been produced by collision between asteroids or the orbit may have just started to coincide with Earths recently. The orbits of everything are affected by everything else - hence my mention of Chaos Theory earlier.

Re: @Chemist - Windows it's like the belly-button

Ah well, you reinforced the belief out there that it's not possible to live life without Windows.

I've heard & seen people saying such rot as "Oh, you need it for banking", "Can't edit HD video without", "3G dongles only work with Windows", "How do you manage RAW camera files ?" and countless others.

The one that amuses me most is "How do you manage as a scientist without Excel?) - well I managed for 20 years before Excel and most of the time Excel was available the data sets I handled were FAR bigger than Excel could handle. Even now I get people to send me data as CSV files and crunch the data with purpose-written C. That's the way to handle 7 million lines of data.

It will not leak out to give less than atmospheric pressure though. At this point there may well be slow exchange of helium/air

This photo slide scanner costs €60... The bundled malware? That's free

Re: Strewth,

Just to flesh-out the comment. The slide I'm thinking about was taken by a Hasselblad, from Pra Gra which is high above a glacial trench near Arolla in the Valais, Switzerland. I've since stood at the same spot and the slide captured it perfectly. Unfortunately I didn't !

A quick search found me a view but not the magnificent slide I remember projected in a large hall.

'Holey code, Batman!' Microsoft to patch 12 vulns on Tuesday

Re: reason for Patch Tuesday

"@TiddlyPom "Security by obscurity does NOT work.

Of course it works"

It helps as part of a strategy - but on it's own it's very risky. The gold hoard is a bit of a red herring as without any clues it really is just a matter of luck whereas scanning (say) IP addresses and ports severely limits the search scope and can be automated.

My router has one open port forwarding to a server for SSH purposes - I've run it for years and the router logs have never shown a SSH access attempt on anything other than a standard port - -the security by obscurity bit is the actual port number is non-standard but I don't rely on that - the only valid username allowed ssh access on the server is very unusual and the password is 20 characters long and horrible. As a further precaution I've now blocked access to ports below 1024 at my ISP

Re: Considering the distances from Earth for the *other* candidates this is pretty close.

I calculate the energy required to accelerate 1 tonne to 10%c as ~5E20 J. According to Wikipedia the sum of energy release from ALL the nuclear weapons test/uses is ~the same. Now I've not read the details of ORION but something seems amiss.

Re: mmmm

I'm glad you posted this because it does help to illuminate the general ignorance around about Linux photo tools - even though I'm just a keen amateur I find it satisfying to convert a good raw photo from my 550D through 16bit programs like darktable or showFoto or do most of the tweeks in ufraw (again 16bit) and final (un)sharpening in GIMP. Even the command-line program dcraw and it's library which are at the back of many of these programs will output 16bit.

Apart from dcraw all these are GUI programs but for efficiency a little bit of scripting around dcraw will convert, resize, enhance an entire directory of raw images into a decent set of jpg proofs ( I use 1080 v) without the large sizes associated with the original .JPGs

e.g.

#!/bin/bash

#

dcraw -w *.CR2

#

mogrify -resize 1624x1080 -quality 100 *.ppm

#

mogrify -unsharp 0x1+.5+0.02 *.ppm

#

mogrify -format jpg *.ppm

I'm sorry but you were the one who said "And yet you guys want to say that you can manage to get your work done on Tablets and Non MS systems. What kind of work do you do ?"

So I told you. This was about MS losing it's stranglehold -well it lost it a long time ago for some people.

"I am sitting at work with three screens (1280 * 3 Wide ) * 1024 High of applications, some of which, the following , of which have no viable Unix/Apple equivalants (Avaya ASA, Business Objects, Visio). I have several VMs open which are usually interfaces to the servers."

Re: chemist

A perfectly valid use for a computer - probably the original.

In any case It wasn't all exotic calculations, there was the real-time use of 3D graphics to study protein structures, analysis with spreadsheets ( no not Excel - that could only handle 16K rows at the time - we had to handle millions) and even writing reports & papers.

In any case dismissing thousands of people using non-MS solutions just because it doesn't fit your world view or experience only shows how little experience of the world you have. There are lots of other uses out there - CGI, stock trading, machine control ( all the NMR and MS spectroscopy machines where I worked DIDN'T use MS software.

The majority, by the way, probably only want a browser. If you mean people who work in offices that might be a different matter.

Re: @Trevor

"And yet you guys want to say that you can manage to get your work done on Tablets and Non MS systems."

What's so suprising about that. Scientist, academics, engineers, designers - lots of them work on non-MS systems. You might not recognize the names of the programs but plenty of them are rather pricy. Before I retired I'd been using Linux plus a host of commercial scientific software for ~6 years, much of that had been ported from SGs and there were several hundred of us in the company so equipped.

A few comments recently have been along the lines "who needs more computing power - machines are fast enough" - well they may be to edit a document or fill-in a form but there are PLENTY of people who have requirements for as much as they can get. My twin Xeon workstation used to run all the time - many of the day-day requirements needed a run of several days and nights and I had a stack of jobs waiting to run whenever the machine was idle. For the really serious stuff there were several 1-2 K node Linux farms.

What wimpy kind of work do you do ?

Re: Hydro Electric Power Stations

No, it isn't !

Weight on ground, energy used to lift weight to height above ground,physics well understood, energy released again as weight falls to ground - really it's not complicated - where on Earth do you think it comes from ?

Just potential energy - it's no hard. If you tensioned a spring the energy wouldn't come from the ground state of the spring -it would come from the muscle energy required to stretch it.

Re: Hydro Electric Power Stations

No, they are sun-powered. Heat from sun, water evaporates, falls as rain, fills reservoirs = stored potential energy. You need gravity to make it work but that's not where the energy comes from.

Linux kernel dumps 386 chip support

Chemist
Silver badge

Re: Z-80

"The 6809 seemed to be one of the best of the 8bit breed"

I think the problem was it WAS rather slow and the complex, elegant addressing modes and position independent code which made it such a great cpu to program in assembler were dying the death as compilers generally only used simpler modes. It was caught at the wrong moment in time really with the 68000 being developed on one hand and the shift over to RISC on the other.

I've often thought that an updated 32 bit with high clock speeds would have been interesting but past is past and I'd much rather have a multi-core modern cpu running at 3GHz even if much of the power seems to disappear somewhere these days.

(I do have a 6809 still running in a home-made Forth system but I guess I've not switched it on in years)
