The solar fireworks at the weekend were recorded by several satellites, including Nasa’s new Solar Dynamics Observatory which watched its shock wave rippling outwards.
Astronomers from all over the world witnessed the huge flare above a giant sunspot the size of the Earth, which they linked to an even larger eruption across the surface of Sun.
The explosion, called a coronal mass ejection, was aimed directly towards Earth, which then sent a “solar tsunami” racing 93 million miles across space.
Images from the SDO hint at a shock wave travelling from the flare into space, the New Scientist reported.
Experts said the wave of supercharged gas will likely reach the Earth on Tuesday, when it will buffet the natural magnetic shield protecting Earth.
It is likely to spark spectacular displays of the aurora or northern and southern lights.
"This eruption is directed right at us," said Leon Golub, of the Harvard-Smithsonian Center for Astrophysics (CfA).
"It's the first major Earth-directed eruption in quite some time."
Scientists have warned that a really big solar eruption could destroy satellites and wreck power and communications grids around the globe if it happened today.
Nasa recently warned that Britain could face widespread power blackouts and be left without critical communication signals for long periods of time, after the earth is hit by a once-in-a-generation “space storm”.
The Daily Telegraph disclosed in June that senior space agency scientists believed the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013.
It remains unclear, however, how much damage this latest eruption will cause the world’s communication tools.
Dr Lucie Green, of the Mullard Space Science Laboratory, Surrey, followed the flare-ups using Japan's orbiting Hinode telescope.
"What wonderful fireworks the Sun has been producing,” the UK solar expert said.
“This was a very rare event – not one, but two almost simultaneous eruptions from different locations on the sun were launched toward the Earth.
"These eruptions occur when immense magnetic structures in the solar atmosphere lose their stability and can no longer be held down by the Sun's huge gravitational pull. Just like a coiled spring suddenly being released, they erupt into space.”
She added: "It looks like the first eruption was so large that it changed the magnetic fields throughout half the Sun's visible atmosphere and provided the right conditions for the second eruption.
"Both eruptions could be Earth-directed but may be travelling at different speeds.
“This means we have a very good chance of seeing major and prolonged effects, such as the northern lights at low latitudes."link (http://www.telegraph.co.uk/science/space/7923069/Nasa-scientists-braced-for-solar-tsunami-to-hit-earth.html)

Hey Arn, have another question.
I have cookies enabled both at work and at home, and today. after already posted couple of times I needed to log back in. I thought that that freaking peecee was well... freaking.
But when I got home my trusted mac also requested to log in again.
Why was that? Did you reset something? Cleared out a couple non-active-users or so?

One thing to be leery of is, yes keep your original ram and if you bring it in for Applecare, make sure to put the original ram back in laptop.
What often happens is the person servicing your laptop will restore it to original specs. So if you machine is a 4GB machine, they might take out your 8GB trash it and put in their 4GB so it matches the computer build. I've read many stories on these forums of people losing their expensive harddrive or ram and got back stock items.

Hi,
I've got a 2007 Aluminium iMac and I've noticed these last few weeks that it is spinning the beach ball a bit more than before and has to have a little think about things when I ask it to do something from time to time.
Time for a spring clean I think. :D
So, can anyone point a tech-savvy person towards some good articles or forum threads on how to get my Mac operating again as it should?
My machine was running Tiger when I bought it and was upgraded to Leopard then Snow Leopard. I've never done a reinstall and to be honest I was hoping I wouldn't have to. I'm 100% comfortable with messing with files, folders, plists and pretty much anything else on the Mac. If I'm honest I'm just looking for a cheat sheet for regaining performance on my machine without having to figure it out for myself... :o
Thanks in advance for any help,
Craig.

Hello World, my first post on macrumors
I tried searching but most of the information was not in recent time, so figured to post a new thread.
I bought a used 3GS 8GB yesterday from a person. The phone is unlocked and jailbroken.
Here is the relevant information:
Version: 4.3.2 (8H7)
Model: MC640LL
Modem Firmware (baseband, i think): 06.15.00
Currently I am using it with T-Mobile, so I know it is unlocked properly.
My question is....
The phone has apps and settings from the previous user. I want to 'reset' or 'restore' or something like that to remove all settings and content from previous user.
If I go to Settings --> General --> Reset and perform a reset, will my phone still be usable with T-Mobile?
Thank you all. Hope I provided enough info to answer.

I have an iPad with 3.2.1 which I jailbroke using jailbreakme.com. I have never upgraded since and I was wondering if its worth upgrading to 4.2.1 and how difficult it is to JB. The website jailbreak was so easy that I could not resist but I don't have alot of experience at this type of thing. I have noticed some newer apps are requiring 4.0 and higher so I guess I will eventually need to upgrade.
I was looking into the VM memory hack and noticed several references that 4.2.1 has this native capability. Overall i'm satisfied with the performance as is but would appreciate your thoughts on whether its time to upgrade and JB again. Thanks.

Well, it's mostly games, which is a pity. I know it's not a gaming laptop but they do sell them through Steam, so I'd like to buy them.
The way you say it, it seems related to the extra power provided by the SB processor. So there seem to be three solutions.
1. Undervolting, which isn't possible right now.
2. Downgrading, and, as in the MacBook Air, fixing another kind of bottleneck (HD operation).
3. Better cooling through termal paste, more fans, cooling pad, etc.
Am I right here? I'd like to know more about this CPU+GPU combo in the same core, because I read it lead to further heating. Is there any truth to this?
Just because it's on steam doesn't mean you need to buy the game... Furthermore, like with Windows, you need to see if the requirements match your system or it'll run poorly.
Under volt is possible. It's pointless though especially if you're stressing the system then the fan will come on or your system will shut down
Downgrade is up to you. But any system, you stress it, fans will come on
Cooling pad just adds to the noise. You can attempt a thermal paste change but like I said, games will cause the system to run fans at max to keep it a good temperature.
It's not so much of a CPU + GPU combo, it's the heat generated by both parts of the die concentrated on a single heatsink. To be honest the older systems genereated about the same amount of wattage wasted in heat so it's not too big of a difference

Yes, that does look very cool. :) Would you please post a pic of how you wrapped the PS printout for the top layer around the rounded corners of the top casing? I didn't understand that. :(
All I really did was put the paper on the back (inside) of the case, and then kind of creased it on the edges where the case curved. That held it in place long enough for me to place the cover back on the computer itself. I didn't glue it or anything, just a simple crease with my finger along the edge. Sorry I don't have any pics, I really can't take this apart again, the screws are really worn and stripped.

I've been using Keynote lately for work presentations. It's annoying not to be able to give them to PC co-workers. PPT such a piece of crap, and i'd like to be able to use keynote more, but sadly it's not super useful anywhere other than my computer.
Export to Quicktime presentation, install Quicktime on PCs.
edit: kayjprod beat me to it.

Seems that Safari or network is about 10% what it used to be in speed. I recently add the MacUpdate Spring Promo package, and seems some of the programs are POC. Not sure if this is part of the problem because the slowdown happened beore that install I think.
OK. Used Tech Tool Pro. All smart status checks ok. All 6 disks check ok. So not a disk problem since it happens on all disks.

I dont think ill have a problem with the wires, myself personally, but in terms of designs i thought that it is comparable because of how the coolmaster isnt confined and it allows more air flow under the mbp. I've read stuff about how you can cool down a mbp even by raising it a half inch propped up against an eraser or something, so maybe thats where the coolmaster excels and because of the price difference, it really just basically comes down to which one does the job of cooling it down better.

The second example is really significantly front-focused, and is shot at f/2.8, so I don't think your focus and recompose technique is to blame (I'd expect a lot less change in focus using the slight focus and recompose you've used here).
Did you lock focus on the eyes and then recompose? Is it possible that you re-focused after you recomposed?

Hello all,
Unfortunately, I don't really have any programming language knowledge. I get by with HTML and CSS but that's about it.
For a project I have, I'd like to create a simple HTML form where a user can select options and/or enter text into fields.
I'd then like the data to be inputted into a database which would allow me to export it and view it.
Is this what MySQL is for? What would be the easiest way to go about this?
What good books/guides would you recommend?
I could actually do what I want offline (as in create a form in a word processor) but am interested in seeing what online options are available?
I realise that if I do this online, I will need to host it somewhere, so if anyone can recommend a free host (ideally offering subdomains on their URL or theirdomain.com/mysite so that I don't have to buy a domain), it would be most appreciated.
I'd also need the access to be password protected.
The concept isn't yet 100% clear in my mind, so any suggestions or advice are welcome.
Thanks,
