Once again my mind has been boggled on the Rachel Maddow show. Tonight she is talking about the problems at shutdown Japanese reactors, reactors that I think were shutdown before the earthquake, not problems with the reactors themselves, but problems with the HUGE POOLS of spent fuel rods, with accumulations of fuel rods in far larger amounts than what is found in an individual reactor. According to her, they need to be cooled for up to ten years before they can be put into dry storage. Having lost their cooling water they could be more dangerous than a reactor cause of the quantity of rods and they are heating up and causing explosions potentially releasing radioactive particles into the environment.
Based on what I said in post #193. Nuclear Reactors can never be truly shutdown. *Without* a continuous flow of cooling water they become dangerous and self destructive very quickly. See this link: The Bane of Nuclear Power- Waste Storage (http://library.thinkquest.org/17940/texts/nuclear_waste_storage/nuclear_waste_storage.html).

Is anybody actually bothering to do this in the wild against any OS?
The types of attacks you are referring to are not occurring in the wild on a massive scale. When was the last time you heard about one in the media?
Again, look, if you're not interested in the mechanics, that's fine. Stop replying to me.
My post is inquiring about the mechanics. For the past hour, I've been trying to find how this thing ticks by searching around for in-depth articles (none to find, everyone just points to Intego's brief overview that is seriously lacking in details) or for the archive itself.
If you don't want to take this discussion to the technical level I am trying to take it, just don't participate.
At the moment, there is no way to prevent the kinds of attacks you are referring to on any OS if a vulnerability exists that allows the attacker to exploit a running application.
I don't know of any other Web browser (this is not a OS problem, it's a Safari problem). that automatically assumes executables are safe and thus should be auto-executed.
Webkit2 will reduce access to user space when Safari (or any app using webkit2) is exploited by restricting the privileges of apps on a per app basis.
What does Webkit2 have anything to do with running an installer on the OS after downloading it ? That happens outside the rendering engine's sandbox. You're not quite understanding what this sandbox does if you think this protects you against these types of attacks.
Turn off "Open safe files after downloading" if you are worried about that type of attack implemented via "safe" files.
I think you missed the part where I don't use Safari. I'm pretty far away from allowing it to "auto-run" "safe" files (I choose what I want to run).
Again munkery, I appreciate you taking the time to respond, but I'm not some noob user. You are not answering my inquiries nor helping any here at the level I want to discuss this. I get everything you are saying. I've been getting that level for quite a few years. I'm trying to discuss at another level here. Do you want to participate or not at a higher level where we discuss the actual mechanics of this rather than just starring at the tip of the iceberg ?

Superb. Replace one fuel reliance on the Middle East with another. Genius idea.
If you want to transport goods with electricity the main off the shelf technology to do that is trains, and to go to India, China and South East Asia from Europe you're going to need to do a deal with at least Iran, Pakistan and possibly Russia, and to go to South America (with a short plane/boat hop across the atlantic at the narrowest point) you're going to need to work with multiple countries in Africa.
Additionally if the US wants to transport goods with electricity from Asia barring some new technology they are going to need to do a deal with the Russians.

That's exactly the reason for the Walled Garden: superior User Experience. The "walled garden" is the reason Apple is so successful today. A controlled, tight, cohesive ecosystem based on a vertical business model - if done right - will *always* be superior to anything else out there. The proof is all laid out before you every day in the tech news feeds.
If Apple had done anything else, it would just be more undifferentiated crap, barely distinguishable from the rest of the flotsam and jetsam out there.
A few people out there just can't stand it that a closed, controlled platform is so damned successful and actually represents the ideal.
Which is ironic considering Steve Jobs lamented the carriers walled garden. I love my iPhone, but I also understand that I traded AT&Ts walled garden for Apples.

I have been working with Msdos/Windows PCs for 20 years and in the past 5 years also with linux (mainly for work, admin web servers by command line). So i guess it's going to be an step learning curve at first, but it has me excited, not worried at all.
You're already multi-OS so the transition will be less difficult for you that someone who has never had to use a different OS.
Most if not all the software i use daily have Mac versions, so i shouldn't have issues with that (Dreamweaver, Photoshop, Firefox/Chrome, Thunderbird, Putty, Ultraedit, Filezilla, Trillian, MSOffice, ssh client).
1) Is there any better mac software equivalent to the one i listed that i use daily?
"Better" is up to you. Dreamweaver, Photoshop, Firefox/Chrome and Office you should try to go with the Mac versions of those programs.
For email clients it depends how you use T-bird.
There are many text editors that are more Mac-y than UltraEdit, but that doesn't make them better. BBEdit is a popular one and has a free version in TextWrangler.
Adium is a popular chat client like Trillian
CyberDuck is a popular file transfer client like Filezilla.
Putty/ssh is a weird one as there doesn't really seem to be a direct equivalent. ssh works from the command line, but I haven't found something that does what PuTTY does in connection management. There are several terminal emulators beyond xterm though.
2) Is the mac command line a full unix one, with same commands, etc? As i said i'm used to linux command line from managing my web servers, and if i can write shell scripts in mac, it could save me good time.
Yes, ... but. Mac OS X is BSD and Linux is mostly System V so there can be subtle differences. Some of the commands may be the BSD versions and may not have all the same options as the GNU/Linux versions. Mostly, you can fix that by also installing the GNU versions from MacPorts.

...but in order for me to buy this box I want it to work without connecting to a computer. Just an easy (read Front Row interface) that would let me buy and watch or listen to my purchased content. Wireless would be perfect. plug this in hook it up to my tv and stereo and all my movies and music are on it. I can buy content and save it there. The only time I would want to connect to a computer would be to back up files and to make room for new content or find old content to stream into the box. I could then take this box with me to a friend's house to watch my movies there.

Most Islamic countries are not inhabitable by homosexuals or religious minorities, your mileage may vary.
The biggest muslim population right now is Indonesia, and they tried banning Christians from using Allah to describe their God. They're also trying to ban the Ahmadiyah sect...
I don't think France or Britain are responsible for Iran's strict implementation of Islamic law and ruthless persecution of dissidents, and to claim that they are responsible is insulting to Muslims because it implies they're far too reactionary to deal with anything using Reason. Just like people who want to ban qur'an burnings and blasphemy because they're afraid of how muslims might react. Are Muslims animals who are so easily goaded? No, they're human beings so they should be expected to act responsibly and not go on rampages at the slightest provocation.
@ the underlined: It's almost like I couldn't even see you move the goalposts :rolleyes:
As for your rant at the end, you've completely missed my point, then used your very own to rant against with your twisted logic. In fact, it was the same exact tactic I was laughing hysterically (in a morbid way) about listening to Hannity in the car last night.
Have fun with your misunderstandings.

So basically what you are saying is that you are a two bit hack and a kid with just an ounce of creativity can easily replace you because any kid can afford a $300 program, whereas a $900 one keeps them artificially out of the game.
The really ironic thing about your post is that FCP 1.0 was a cost revolution itself bringing video editing to he masses for really the first time ever, which you took advantage of. Now that Apple is doing it again and you are at risk you seemingly outraged.
Try and get your facts right before spouting off and obviously you are no pro app user. Premier was before FCP and FCP was taken from premier as the person who built FCP was the same. Premier was the first cost revolution not FCP.1 as Macs didn't sell many at that point. It stands to reason that if you dilute something in price it will then be worth less, and in business you need a premium product to keep your head above water.. Its all very well Apple releasing garage band as this is ment for kids and individuals to play around with and when or if they decide to go and pursue this for a career they can up sell them to Logic or Pro Tools etc. This is a huge step up for that route, but what I am saying is this: If everyone has the same tools then how can it be called a pro app? The new FCP is pretty much based on Imovie and for those who dont except that try and use them both together and then you will see.
Take the Red camera.. this could sell for 5k and everyone would have one, so why would you pay a daily rate of $1500 to have someone use a camera that only costs $5k? Wake up and smell the coffee but as your post indicates you dont live in the real world as companies will pay more for something they feel is better than it really is. Its simple business logic and psychology. Companies pay a premium for a professional using professional gear not an app you download from the app store.
I think that is 'Professional' world that your living in is starting to change. Applications aren't just a forte of a few high and mighty code monkeys. For example I could go get Xcode off the App store and download it for 5 bucks, thats all you need to make a Killer iPhone app, 5 bucks. Angry Birds, made millions of dollers, and it started with 5 bucks. It could be used by a Fortune 500 company to create a in-shop app that can do much for the company, or it can be used by some kid in his room to create a game. This idea of there is a special elite out there is changing. Technology is embraced by everyone, and everyone born today will have the same oppertunity's to use them. Computers or Video Editing isn't just something that is done by geeks in a basement on some College campus using machines the size of desks. Its done by Granny's, Kiddo's, everyone. High Definition cameras are affordable to anyone with a little skill in saving. People aren't gonna need 'Professionals' forever. Why hire a Photographer for a wedding, when I can afford just as good Camera, photo editing software for less then it would be to hire them?
We can't keep professionals around just for the sake of keeping them around. If they are productive, if society needs them, then they will do fine. I'm sure your industry needs you, and plenty of regular joe's do to. But not forever, definatly not with the next generation of script kiddies and technology savvy teens.

ABout the only real use I saw for thi sdevice was for the stuff Ihave recorded form elgato 500. Sinc eit dumps it into my itunes library - theoretically I should be able to access it. However, 5 gig files streaming are simply not pretty - and I do not want 640 * 480 on my HDTV.
WHile I "get" the direction of this product - I am not sure where its marketing position is at. Most can easily buy an upconverting DVD player for around $50-60 - connect to their TV and buy tons of movies (and own them) at 10-15.
Much higher resolution - no streaming issues...in fact for the average user this is a MUCH easier solution than downloading a movie - figuring out how to enable their various "apple" wireless devices to talk, connecting this box to the TV and dealing with any streaming hiccups....And they also get a much higher resolution - filling up their whole widescreen. Most users already complain about the black bars across the top and bottom - can you hear it when the entire "dvd download" is letterboxed?
I really wanted to like today's announcmeents - and now am just confused.

Two weeks ago my service was flaking out. Couldn't make calls or get to 3G all day. Wasn't too happy. Wentthe AT&T store to go vent and the hottest clerk, I have ever seen, was working. She was so hot, she should have been over at VS in VS modellling something for me. wink, wink. nudge, nudge. ;) She said they were working on a go-live of 12 new towers. The engineers had screwed up the configs. So the new towers and some of the old towers weren't playing nice with network. I live in mostly Verizon country. AT&T has been making improvements out the whaz. They finalized the deal for Centennial Wireless. Alot of those towers flipped to ATT recently. So for me, my piece of the network got bigger & better. Now mind you this girl was so good looking she could have told me to set my iPhone on fire and I would have given it serious consideration. It seems like AT&T is trying to act like it cares. So back to mis hottie. I asked for her phone number. ANd she told me, 1-800-331-0500. I think she likes me.

So what you are saying is skunk was correct in every respect (and he was) but you just had to argue anyway.
No, I'm not saying that. Skunk said Ciaociao's Latin sentence was meaningless. But I figured out what it meant. So it wasn't meaningless.
Is that something taught in the catechism? Based on this thread I'd been wondering.

I think this thing is perfect, especially for a person like myself who does not watch a ton of TV. In the end it will be cheaper for me just running one of these on my TV and subscribing to a couple of shows as opposed to spending money on cable or satellite. The built in HDD is an interesting development, I'm curious to see what that might bring about. But as it stands, I'm sold, lol.

Apple doesn't care what you plug into the 30 pin adapter. Go here (http://www.itechnews.net/tag/iphone-controller/) to see all kinds of button-rich controllers for the iPhone, iPod Touch and iPad. Some plug into the connector and some operate the game over wifi, and one allows both methods. Before commenting, let Google be your friend. :)
By all kinds did you mean 'all three'? That's all there is on your link. Before exaggerating, let being realistic be your friend. :)

I guess all this honour killing pretty much explains the original theory how freedom of women has been affected
thanks again edifyingG for presenting some very valid points
The freedom of women is an archaic subject. It is established that women generally had less rights as we go back in time.
It is worth noting that it was during the Islamic empire that the first big scientific advances in medicine were made.
Things were far worse before Islam.

It skews the number non the less. iOS is on four different devices the iTv, iPod touch, iphone, and the ipod touch jumbo. And google doesn't make any hardware. They work with companies to have them made like the nexus series.
It's not skewing the number at all because that's the addressable market for any developer developing on iOS.

I don't want to seem judgemental, but the last thing I ever plan on doing is selling my G5 Quad. I mean like I will have my G5 Quad until I DIE. Why would you do that? It runs classic. It runs Adobe native. It is pretty fast for email and word processing. ;) And it runs dead silent. It's the perfect backup for when the Mac Pro goes down. At the very least it makes for a great HDTV player and recorder with EyeTV 500 or Hybrid attached.
AMEN Multimedia!!!
Amen.
I will NEVER sell my Quad G5 -- it is an AMAZING Unit. Simply awesome.
I will buy all the new Apple Mac Pro toys -- buy I will always have the Quad G5. Always. It is a legendary machine.

SNIP (Just to save space)
I know thorium doesn't have an awesome past, especially in early development. That said, I think with more development it's liable to be a better alternative to uranium. What you said is all true, however you're citing an experimental reactor; things just aren't magically perfect, sadly.
To quote one of your articles: It was 15MWe, 46 MWt, and was used to develop and test a wide variety of fuels and machinery over its lifetime. Its Helium outlet temperature was 950�C, but fuel temperature instabilities occurred during operation with locally far to high temperatures. As a consequence the whole reactor vessel became heavily contaminated by Cs-137 and Sr-90 [1]. Concerning beta-contamination AVR is the highest contaminated nuclear installation worldwide as AVR management confirmed 2001
Notice the part about it being used to test a wide variety of fuels and machinery? Also the fuel temperature instabilities? That's what caused the Cs-137 and Sr-90 contamination, as noted above. A reactor that's properly designed (with properly fabricated fuel) won't have the disadvantages of a test reactor, and shouldn't have that contamination. I'm not saying it's perfect now, but controlling those instabilities shouldn't be an issue, especially in light of salt or liquid fuel possibilities. Furthermore, what about MSR? It's not a pebble bed; it's molten. That itself should even out the fuel temperature instabilities a little, just the liquid fuel based system.
You raise a very valid point about Thorium, however I think one instance of a test reactor hardly justifies dinging the entire concept because the initial reactor wasn't designed well (see the cracked bottom of the AVR...), but rather it serves as a basis for future designs. Also, what about India planning to use thorium? They're not approaching this with guesswork-- there's clear advantages to using it over uranium. Differences in opinion I guess, but hey, to each his own.
EDIT: Also, I know my initial wording was a little fuzzy; what I meant to say was PBR with uranium, and MSR with thorium-- at least for now.

True, but hardly going to provoke torrents of postings of heated debate and disagreement - surely a necessity in modern society :p
So that's 2 cents of irrational exuberence then?
no. just enough to get a decent woody going:D

Boy, I've read the first few pages of this thread and have come to the overwhelming conclusion that most people posting differences on here between Windows/OSX simply don't know how or haven't learned yet how to fully use OS X. The majority of complaints seem to simply be people who don't know the key commands to do what they're blaming OS X for lacking. If something is that disruptive to your workflow why aren't you guys doing the minimal amount of research it would take to solve the issue?

That's a failure of the German politicians to make a case for nuclear power there (although I imagine that Germany has good potential for hydropower and other renewables).
I think that the opposite could be said for the UK. Over the last few years opinion has turned more pro nuclear. In contrast to Merkel, Cameron turned the Japanese situation into a positive - saying that the UK could 'learn lessons' and make nuclear even safer.
There's too much hysteria over this. This plant has been hit by a force 9 earthquake and a tsunami and yet although some radiation has been released this is by no means anything like as serious as Chernobyl.
In a world where the security risks and economics of oil and natural gas are on their way to being untenable and the renewable energy options cannot realistically meet the world's ever growing energy demands, the benefits of nuclear fission far outweigh the risks, particularly when you consider that the public and worker fatalities relating to fission reactors are dwarfed in comparison to those from energy generation from fossil fuels, petrochemicals and natural gas.

This is not really true. You need to know the software to make it do what you want to do. You don't need to be an expert certified user, but you need to know your way around.
Of course you do. I agree completely. Obviously the poster is exaggerating. I assume he means that the editors he speaks of aren't techno geeks like a lot of us here on MacRumors.
I seem to have misspoken. I meant they don't need to know the acute technical details of their software.
