I'm really happy with my two Samsung SA450s. I paid under AU$300 each for them, and they rotate, so it's a pair of 1920x1200 screens, one sideways for code. With a decent graphics card (I splurged and got one that costs about the same as one of the monitors so I could have two separate DVI links) it's a nice programming rig. The sideways one gets over 100 lines of code on screen at a readable resolution.
You know what, I've never used it. I've never even visited their site - but I've heard of airbnb.
It's kind of the best known service in its "class".
Your question would be similar to "Are we all supposed to know what Netflix is?". In theory you may have not heard of it if you've been under a rock for the last N years (I've never used Netflix either).
How's the cost of bandwidth to the rest of the world? Last I looked, hosting in Australia wasn't viable if you have a serious international customer base.
Shit-slow unlink speed I think. My use-case is massive mail-server filesystems where there are millions of small files. The performance limiting factor is almost always unlinks with any filesystem.
I never saw that running on decent hardware with battery backed RAID units. I saw significant dataloss the one time I tried XFS (all of - ooh, a month ago) and had to nuke the entire server and start over.
We run ext4 rather than reiserfs mostly now, but it served us well for very many years.
Mind you - I did try reiser4 on my laptop for a bit back in 2004, and I had dataloss there. Never had dataloss with reiser3 though, except the really early versions. Even then it was a lot better than ext2, which was the alternative at the time.
That's what happens when you adopt early, you get earlier revisions of stuff.
The alternative would be to never upgrade for fear of making the early adopters sad. Of course there has to be a balance, but most non-assholes accept that this is how things work.
On the plus side, they actually HAVE their Pi now, and have had the use of it already. If they hadn't bought it (collectively), there would be no Pi.
Yeah, and I remember well when Berkeley Uni on their shiny expensive-disks SAN had their whole email system go up in flames for over a week due to a single failed drive and the extra IO hit to recover. When the same thing happens to me with the cheap SATA crap we use, I just move all the masters from that machine to other machines and let it rebuild. No loss of service, minimal impact spread over a large pile of users.
Apart from a really bad batch of 300Gb 10kRPM drives a couple of years ago, it's been very easy. Roughly one failure per month. Systems designed for rapid failover. No worries.
Even in the horrible case where I lost a whole machine and had to rebuild from scratch, only about 5% of users were affected by noticable slowdowns because they were on the source drives for the re-replication, and had to compete for IO. I could have reduced the impact on them by slowing the replication, but that's longer without full redundancy.
(this is all RAID1 as well)
There's more than one way to do it. I care about our users' data plenty, which is why it's on 6 separate live spindles PLUS backup.
How is that different from just picking another one of those 5 and calling it SHA-4? It's not like they magically go away because one has been given a version number all of its own.
No, because there are other things blocking your body from flying. But if you get thrown in water and flap your arms around in different ways, each time seeing what worked and adding more of that - eventually you might become a pretty good swimmer.
Annoyingly, kids learn passwords really fast too - we haven't solved the problem that for at least the older parents today, technology wasn't a part of their lives growing up so much, and we don't have good processes for managing those risks baked into our habits.
Things that can cost money online just don't have the tangibility of real cash... and I don't have a super-good solution for that. Even my older and pretty internet-savvy kids happily start watching youtube movies when given a moment to check things online when the link is going via my phone and bandwidth isn't cheap like it is at home - they can't tell the difference.
You know what, I've seen your comments on other threads and sounding off about how other people live their lives without having walked in their shoes seems to be a theme. Oh well, carry on. Maybe one day you'll have kids and you'll realise that it's not quite the same as you imagined.
I guess your plan is to tie your children (if you ever have them) up ever time you have to go to the toilet? You can't helicopter them 24 hours of every day - so you remove anything that's dangerous enough to kill them and let them explore their world.
A tablet PC isn't dangerous except that you can spend a lot of money on it in ways which are DESIGNED to be attractive to kids. There's nothing else just sitting there in the house that can do it - even with an old-style phone it's pretty hard for a kid to do a lot of damage.
Probably quite true, but I still don't have any control over that unless I'm a very big customer. But they require java because someone, somewhere, believed the glossy brochure which said that Java would solve all their problems and make them coffee while I did so.
C and C++ doesn't have "write once, debug everywhere" emblazoned all over its marketing.
There's a difference between not claiming something, or claiming it and then not providing it.
In the second case, people make assumptions (like shipping stuff that's supposed to have a long shelf life and work cross platform in your langauge), because they bought into the hype.
That's what I object to. Stuff written in Java which doesn't work everywhere.
Still, the vendors of things which require badly written java to work have plenty of blame to share too.

But hey - they've been mentioned on slashdot before... so yeah, I guess you are expected to have heard of them. I certainly remember reading http://tech.slashdot.org/story/11/07/31/0013236/sfpd-arrests-suspect-in-airbnb-rental-trashing when it happened.

Been really impressed with NYI - we haven't had a single glitch at FastMail either.
We have an emergency backup plan (Iceland) - but it's nice not to have to use it.
Man - I should wander back to the other place and read your war stories.
So when is Oracle going to release ZFS to the Linux world rather than pushing btrfs which is still not finished?

Sorry - which filesystem did you author which is significantly faster and more reliable than reiserfs thanks to your superior knowledge of the field?

Mmm, Pi.

Not taking the word of the Prime Minister at face value is an Australian tradition.
Similarly when a person dies, their house should be burned down immediately along with all their belongings.

Long term something else may have replaced ipv6 - y'know, something actually massively better - not Blu-Ray better.
Companies which wait longer skip over an intermediate layer of pain in that case. Lucky for them.
Seems to me they sold a product and made money from it - so your "should have" probably doesn't carry much weight with them.
If you really think anyone can do the job I recommend you peruse this site some.
Wow. I think the follow up comments are more telling than the original post. I couldn't believe that so many people would not understand a singleton!
Whoosh

Let me guess, you have children?

Wow - yeah, a 4 month cooling off period before declaring war. Which everyone else in the world know about. What could possibly go wrong?
