As far as "distributed redundant system", strongly suggested you read Moans Nogood's essay "You Don't Need High Availability" and think very deeply about it before proceeding.
I agree that you shouldn't go for a HA solution if you don't need it, and that it is much more costly. However I've worked on a 6 9's availability (99.9999% uptime) system where we mostly met that target and sometimes it is needed and is worth doing.
You literally can't buy a server these days with less than 2 cores, and getting less than 4 is a challenge.
Does it matter how many cores? They're cheap! 4 times the chance of failure is my only issue. In any case it sounds like he could combine services WITHOUT the overhead of visualization.
Even the other listed services probably cause negligible load. Most web servers sit there at 0.1% load most of the time, ditto with ftp, which tends to see only sporadic use.
Yes but it's the rest of the time that actually counts. It doesn't matter if you can handle low load periods if you can't handle high.
I think you'll find that the exact opposite of your quote is true: for 99% of corporate environments where actualization is used, it is appropriate. In fact, it's under-used. Most places could save a lot of money by virtualizing more.
Visualization has distinct advantages, and utilisation is certainly one advantage but if you require high availability and can't predict peak loads accurately (across all services simultaneously!) it may well not be appropriate. The bigger advantage of virtualisation is the ability to bring up your virtual machine on a completely different piece of hardware should your existing hardware fail. You can achieve similar without visualization, but I find that more compelling than the utilisation argument, which frankly is just a sales ploy for most cases.
I'm guessing you work for an organization where money grows on trees, and you can 'design' whatever the hell you want, and you get the budget for it, no matter how wasteful, right?
Yeah that's why they're using the same infrastructure for 7 years running, right?
I hate it when slashdot descends into this kind of childish petty character attack. It's not conducive to a reasoned discussion.
There's a lot of handwaving about how Chrome is not Windows, how it won't let you use photoshop on the netbook, as if you would. Here's a hint: if you're trying to run Photoshop on a 10" screen, you're doing it wrong.
If you're a photographer doing rough edits and need quick turn around (eg. journalism, even wedding photography these days) a netbook that allows you to do quick edits is a much better option than an image tank (hard drive plus card reader and undersized screen for backing up photos). Price is similar. Size unfortunately is not so some will still use the image tank option when size counts (eg. if travelling). Of course an even better option is a small laptop that's capable of burning to CD or DVD.
Sure if you're trying to do highly detailed work on a netbook there are probably easier ways. But don't knock it just because it's not YOUR use case.
The marketing companies of the West aren't interested in fighting their battles. Stop expecting ad pimps to be responsible for liberating anyone. Instead, raise your expectations of the Chinese.
Stop expecting the Chinese to be responsible for liberating anyone. Instead, despair.
Excellent. So as a developer you're not just rude, abusive and unprofessional, you're also a one trick pony who worships at the alter a single methodology, and have an uncanny knack for convoluted useless metaphor. Please file your resume here in the filing cabinet marked "Waste bin". Don't let the door hit your arse on the way out. I'd really like to think you're just trolling but unfortunately I have had the misfortune of working with your ilk before.
ROFL! The only thing you know about agile is that is is a buzzword, that's it.
Wow. You're an amazing person. You must be very well paid to be able to work out how much I do or do not know about agile from a single post. Yes that was sarcasm. In case your too obtuse it means I think you're a wanker and you know nothing about me.
My company uses agile effectlively, and everyone knows that agile is comprised of iterations (typically 1, 2, 4 weeks or whatever you want).
Everybody knows squat. I've seen agile applied well and I've seen it applied poorly and everything in between.
The iteration is comprised of stories to be completed. Nightly builds are just automated builds that are done daily or nigthly, hence the name.
Thanks for the info. I thought I should return the favour by providing equaly non-obvious information so here it is: Green is a colour.
This has nothing to do with agile, why would it? Makes no sense to show clients code that is incomplete and between iterations... LOL@YOU.
LOL@YOU? Really? I hope you're more professional at work.
Nightly builds are typically NOT complete code, you moron.
How's that non-agile, waterfall QA working out for ya?
How's that constantly changing never quite know what you're building agile shitfight working for you?
See it ain't hard to be immature. It ain't clever either. Some incredible projects have been built with both methodologies and there have been some abysmal failures with both too.
The android market is a lot newer and there are many fewer devices sold. Complaining about not having as much revenue through that stream is asinine. Article author is a whiner and has nothing to contribute but bile. Either that or this is just a thinly veiled bit of Apple propaganda. Either way: BBBBOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!
What does MS offer nightly builds for??? It's just not how they work. They're a typical monolithic development house that deals only with releases and occasionally lets beta code out. There are benefits to the approach like not trying to shoot a moving target when it comes to bugs etc. People who've grown up with agile seem to think it's the only way to do quality assurance.
The BBC has an article today - What happened to Second Life? Seems like a bad day of news for the decreasingly popular SL.
In Australia, our largest ISP (Bigpond) has just announced unmetered usage of second life are now going to be metered. I think they also closed their content (a "Bigpond Island" which they had paid staff to create) citing this as a failed experiment.
Linden Labs need to be revitalising Second Life - offering more to retain and get new peeople. Instead they seem hell bent on self destructing.
Oh well from my point of view Second Life wasn't good for much more than crappy voice chat with lame avatars. I never spent money on it as the only thing I truly liked was the ability to fly. That doesn't stay amusing for very long.
Careful there. You're bringing a well reasoned and rational argument to the environmental debate. If you've dealt with these fuckwits you should know by now that this is not allowed. You're suppose to bleat like a sheep every time they bring in a new measure that means you have to sacrifice, while someone else profits in the name of the environment.
. If anyone, it should be Stallman, for writing the GPL, for starting the free software movement and spreading knowlege of the existence of free software and for explicitly backing a public cause, and basically dedicating his life to it.
Yeah but Stallman's already given himself a sainthood. Poor Linus has nothing.
What the fuck? That doesn't even make sense. You're going to judge people based on the random thing they are doing when an emergency hits?
No, I'm just not convinced that an on screen emergency alert IN A FUCKING GAME is the right way to let people know there's an emergency happening. What I meant is that if there's an obvious state of emergency and people are still online playing a fucking game that's their problem. That should have been clear to anyone.
The tiny proportion of people playing an online game is an awful target. Loudspeakers on the street would probably be more effective even though it's not very effective at all.
The difference between WOW and TV is TV is a traditional medium for delivering the news and TV reaches a much wider community than that of a single online game (or small group of them).
You might as well create a special information group that knocks on doors. At least they wouldn't fucking ask you if you were playing WOW or chess or some shit.
Uhh... really? It's an *EMERGENCY*. I think when someone tries to go attack New York again, people will be willing to miss a few headshots to get the best possible warning they can. Its not like these announcements are sent out often.
If there's an emergency and you're still at your computer playing WOW you deserve what you get. You haven't convinced me: This is still one of the stupidest ideas I've ever heard of.
The upside would be having a software program whose name is not a pejorative term in the English language.
The upside is that you wouldn't encounter as much resistance getting your boss to permit the installation of GNU Image as you would GIMP. It sounds more professional so you sound more professional. I do not want to be mentally associated with the word GIMP when my boss is doing my review.
On Windows there's also my personal favorite, Paint.NET. It does WAY more than Paint, it's fast, and it's free. It ain't Photoshop, but it's all I need.
If you started using layers and doing some slightly more advanced stuff you'd realise Paint Paint.NET GIMP Photoshop. Paint.NET is missing a heap of features and facilities that you can learn about (or not) in GIMP, so it's much more limiting if you want to improve your photo editing skills. It's a great tool for a quick and dirty (albeit limited) editor, but I've well and truly outgrown it. What I (and many others) really want to see is a few more Photoshop features in GIMP. Adjustment layers is probably first on my list.
If he's not from the UK it's really not so amazing. Why should he care? (Except in so far as it sets a precedent for other countries to follow when the UK passes a draconian law)
Me? I'm not from the UK and I think the way you've been going you could have saved yourself a lot of trouble by siimply surrendering to Hitler during WWII. Did I just Godwin myself? Oh well Godwin's asinine "law" is another thing I don't give a monkey's testicle about.

For a same screen size an LCD will consume less than a CRT, but most people who change their TV go for a much bigger screen that negates any benefit.
No benefit? Are you kidding? Have you seen my fucking awesome huge TV? Mine's bigger than yours so nyer!

...he would refuse it anyway, on the grounds that it wasn't called the "GNU/Nobel Peace Prize".
No, you're thinking of Richard Stallman. He'd also refuse on the basis that they might require him to shower for his acceptance speech.
. If anyone, it should be Stallman, for writing the GPL, for starting the free software movement and spreading knowlege of the existence of free software and for explicitly backing a public cause, and basically dedicating his life to it.
Yeah but Stallman's already given himself a sainthood. Poor Linus has nothing.
For normal humans that would be correct, but this Dali Lama is the reincarnation of the last 14 Dali Lamas.
He laughed in his first couple of incarnations, but then the joke got old.
Technically true, but you're forgetting Linus' herring genocide of 1997.
I'm confused. The herrings were Iranian???
Why not? I mean, sure Torvalds isn't exactly a Ghandi (who ironically never got one, IIRC)...
I'll say. When asked to comment Linus said "They're smoking dope, but I'll take it anyway".
